Technical Field

[0001] The utility model relates to the technical field of packaging, in particular to a capping device for a packaging barrel. Background Art

[0002] Our company produces a liquid product. First, it is filled into a plastic packaging bag, heat-sealed, and then the packaging bag is placed into a plastic packaging barrel for secondary packaging. The purposes are as follows: Firstly, it can enhance the protection of the liquid product. Since the capacity of a bag of liquid product is 3 liters to 5 liters and the volume is relatively large, if only the packaging bag is used for packaging, the packaging bag may be punctured due to accidental situations during transportation or sales. Secondly, using the packaging barrel for secondary packaging can enhance the aesthetics of the packaging. Thirdly, it is convenient for storage. The problem is that after the packaging bag is placed into the packaging barrel, the lid is manually covered on the packaging barrel, and then a hammer is used to repeatedly strike the lid several times to complete the installation of the lid. The above process relies on manual labor and needs to be improved. Content of the Utility Model

[0021] As Figure 1 , Figure 2 shown, this embodiment provides a packaging barrel capping device, including a first motor 1, a rotating plate 2, a pressing block 3, a pull rod 4, and a limiting cylinder 5.

[0022] Specifically, as Figure 2 , Figure 3As shown, the limiting cylinder 5 is vertically arranged and fixed on the support plate, the support plate is fixed on the first bracket, a vertical rod 31 is arranged on the top of the pressing block 3, the vertical rod 31 passes through the limiting cylinder 5 upward, the vertical rod 31 slides up and down to fit the limiting cylinder 5, the lower part of the pressing block 3 is used to place the packaging barrel, the outer diameter of the pressing block 3 is larger than the outer diameter of the packaging barrel, the first motor 1 is arranged on the first bracket, the output shaft of the first motor 1 is connected to the rotating rod 11, the rotating rod 11 is fixedly provided with a collar 12, and the outer side of the collar 12 is provided with two A toggle rod 13, the two toggle rods 13 are symmetrically positioned, a ring 21 is provided at one end of the rotating plate 2, and a base 22 is provided at the other end of the rotating plate 2. The ring 21 is rotatably matched with the rotating rod 11, and the ring 21 is located between the ring 12 and the first motor 1. A cylinder 23 is provided on the side wall of the rotating plate 2. When the ring 12 rotates, the toggle rod 13 is used to toggle the cylinder 23. The pull rod 4 is located above the vertical rod 31, and the top end of the pull rod 4 is rotatably connected to the base 22, and the bottom end of the pull rod 4 is hinged to the top of the vertical rod 31.

[0023] How to use: Figure 2 From the perspective, the first motor 1 continues to drive the ring 12 clockwise, and the toggle rod 13 will toggle the cylinder 23 clockwise, thereby prompting the turn plate 2 to rotate clockwise. When the turn plate 2 passes the 12 o'clock direction, it moves downward under the action of gravity of the pressure block 3, thereby quickly pulling the turn plate 2 clockwise, and then the turn plate 2 stops at the 6 o'clock direction, waiting for the toggle rod 13 to toggle the cylinder 23 clockwise again. Note that the installation task of the cover is completed when the pressure block 3 moves downward.

[0024] In order to make the pressing block 3 move downward more quickly, Figure 4 As shown, in this embodiment, a spring 51 is provided in the limiting cylinder 5, and a convex plate 311 is coaxially provided on the vertical rod 31. The diameter of the convex plate 311 is larger than that of the vertical rod 31.

The lids are located within the area surrounded by the four limiting rods 81. The power source of the lifting table 71 can be a cylinder, an oil cylinder or a hydraulic drive. The lifting table 71 is used to move the stacked lids upward as a whole. The second motor 72 is arranged on the second bracket. The output shaft of the second motor 72 is connected to one end of the cantilever 73. The lifting assembly 74 is arranged at the other end of the cantilever 73. The bottom of the lifting assembly 74 is connected to the suction cup 75. The power source of the lifting assembly 74 can be a cylinder, an oil cylinder or a hydraulic drive. The lifting assembly 74 is used to adjust the height of the suction cup 75. The suction cup 75 is provided with a vacuum adsorption assembly for adsorbing the lids. When the cantilever 73 rotates, it is used to move the lid above the packaging barrel.

[0026] The usage method is as follows: Use the conveying table 6 to convey a packaging barrel to the lower part of the pressing block 3; Use the lifting assembly 74 to move the suction cup 75 downward. After the suction cup 75 adsorbs a lid, it moves upward to reset; Use the second motor 72 to drive the cantilever 73, so as to move the lid above the packaging barrel; Use the lifting assembly 74 to move the suction cup 75 downward, so as to cover the lid on the packaging barrel; After the suction cup 75 releases the lid, it moves upward to reset. Use the second motor 72 to drive the cantilever 73 in the reverse direction. After the cantilever 73 resets, the pressing block 3 moves downward to complete the installation task of the lid; The lifting table 71 moves the stacked lids upward as a whole, so that the suction cup 75 can adsorb the next lid.
