Manufacturing method of milk powder tank lid opening device

The invention relates to a lid opening device, in particular to a milk powder can lid opening device.



Background technique:

Milk powder is a powder made by removing water from milk, and it is suitable for storage. Fresh milk or goat's milk as raw materials, frozen or heated method to remove almost all of the water in the milk, add appropriate amounts of vitamins, minerals and other processed foods after drying, milk powder is generally made of metal cans It is convenient to carry. Milk powder can be used for brewing and drinking, making coffee milk, ice cream, etc. The above manufacturers' stores will need a lot of milk powder, and in order to ensure the tightness of the milk powder tank, it needs to be tightly closed after using the milk powder to avoid milk powder. It expires or lumps early, so opening the lid of the milk powder container is more laborious.

At present, tools such as knives or spoons are usually inserted between the lid and the top of the milk powder can, and then the can opening tool is pushed down with the top edge of the milk powder can as a fulcrum to pry the lid open. It is necessary to gradually pry open multiple points. Efficiency It is low, and the lid can be easily deformed, which affects the sealing effect of the milk powder can.

In addition, because the gap between the lid and the top of the milk powder tank is very small, it is easy to slip when pry open with a tool such as a knife, resulting in hand injuries.

Therefore, we have designed a milk powder can lid opening device that can quickly open the lid of the milk powder can, and can ensure that the lid is intact and not deformed when it is opened, and it is not easy to hurt the hands when the lid is opened.

Then pull the u-shaped handle 70 upward to move, so that the milk powder can lid can be opened.

Embodiment 2

Please refer to FIGS. 1 and 3, a milk powder can lid opening device, which includes a first ring 1 and a sliding plate 2. The left and right sides of the bottom of the first ring 1 are provided with sliding plates 2 and a plug plate. 3. The sliding shaft 5 and the cover opening assembly. A sliding plate 3 is provided at the bottom of the sliding plate 2. The sliding plate 3 is connected to the sliding plate 2 by bolting. The sliding plate 2 is provided with an inclined groove 4 and the inclined groove 4 is 45. The sliding shaft 5 is slidably fitted in the chute 4, and the first ring 1 is provided with a lid opening component, which is used to open the milk powder tank lid.

When the milk powder can needs to be opened, the user places the plug plates 3 on both sides against the outer edge of the top of the milk powder can and is located on both sides of the lid, and then operates the lid opening assembly to insert the plug plate 3 into the lid and the milk powder can. Between the gaps, then hold the milk powder can with your other hand, and open the lid by the lid opening assembly, which is easy to operate.

Please refer to FIGS. 1 and 3. The cover opening assembly includes a clamping rod 8, a second ring 9, a connecting base 10, a guide rod 12, a supporting base 13, a special-shaped connecting frame 14, a second spring 15, and a grip 16 And the limit assembly 11, the left and right sliding plates 2 are provided with clamping rods 8 symmetrically on the sides, the clamping rods 8 are perpendicular to the sliding plate 2, a second circular ring 9 is arranged below the first circular ring 1, and the top of the second circular ring 9 is left and right There are connecting bases 10 on both sides. The top and bottom of the left and right connecting bases 10 are provided with a limiting component 11. The limiting component 11 is used to restrict the upward movement of the clamping rod 8. The clamping rod 8 is initially located in the limiting component 11. There are guide rods 12 on the left and right sides of the ring 1, the guide rods 12 are perpendicular to the first ring 1, the guide rod 12 and the connecting seat 10 slide-fit, and the left and right sides of the second ring 9 are provided with support seats 13, The support base 13 is located on the outer side of the connection base 10. The left and right support bases 13 are rotatably provided with a special-shaped connecting frame 14, one end of the special-shaped connecting frame 14 is connected to the sliding shaft 5, and the connection between the connecting base 10 and the special-shaped connecting frame 14 is A second spring 15 is connected, and the left and right sides of the second ring 9 are provided with grip handles 16.

When the cover of the milk powder tank needs to be opened, it is inserted from the top of the milk powder tank through the inserting plate 3, and the top of the inside of the connecting seat 10 is abutted against the top edge of the milk powder tank, thereby limiting the downward movement of the lid opening assembly. Hold the top of the milk powder tank and be located on the outside of the lid. The user holds the left and right grips 16 and presses down, and then presses one end of the special-shaped connecting frame 14 with his finger, so that the special-shaped connecting frame 14 uses the support 13 as an axis. The heart oscillates, the sliding shaft 5 moves, and the second spring 15 stretches. Under the action of the limiting component 11, the upward movement of the clamping rod 8 can be restricted, and the sliding plates 2 on both sides pass the sliding shaft 5 and the chute 4 When they are close to each other, the clamp rods 8 move within the limit assembly 11, and then the plug plates 3 on both sides are moved closer to each other and inserted into the gap between the lid and the milk powder can. At this time, the clamp rods 8 are separated from the limit assembly 11 and used. The person continues to press the special-shaped connecting frame 14, and the special-shaped connecting frame 14 drives the sliding plate 2 to move upward, thereby pulling the cover out through the inserting plate 3, and the guide rod 12 plays a guiding role. In this way, the inserting plate 3 can be more accurately inserted into the cover. Between the milk powder container and the hand You can open the lid while holding the milk powder tank, which makes the operation more convenient.

Please refer to FIG. 2-3. The limit assembly 11 includes a connecting plate 111, a wedge-shaped block 114, and a torsion spring 115. A connecting plate 111 is provided on the top of the connecting base 10, and the connecting plate 111 is vertically arranged. A first groove 112 is vertically opened, and the clamping rod 8 is initially located in the first groove 112. A second groove 113 and a second groove 113 are provided on the connecting plate 111 on the front and rear sides of the first groove 112. A wedge-shaped clamping block 114 is rotatably provided on the inner and upper parts, and a torsion spring 115 is connected between the wedge-shaped clamping block 114 and the inside of the connecting plate 111.

When the special-shaped connecting frame 14 uses the support base 13 as the axis to drive the sliding shaft 5, the two-sided wedge-shaped blocks 114 can restrict the upward movement of the clamping rod 8. When the two sliding plates 2 move closer to each other and the clamping rod 8 moves out of the first groove At 112 o'clock, the slide plate 2 can be moved upward by the slide shaft 5. After the special-shaped connecting frame 14 is loosened, the special-shaped connecting frame 14 is reset under the action of the second spring 15, thereby driving the slide plate 2 and the clamping rod 8 to reset. When the clamping rod 8 is reset downward, the two wedge-shaped clamping blocks 114 are pressed to the first position. The two grooves 113 swing in the direction and the torsion spring 115 is compressed. After the clamping rod 8 is completely reset, the torsion spring 115 drives the wedge-shaped clamping block 114 to reset and restrict the clamping rod 8 again, which facilitates subsequent cover opening work.

The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited to this. Any person skilled in the art can easily think of changes or replacements within the technical scope disclosed by the present invention. It should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
