Description

Technical Field

[0001] This invention relates to a double-headed tin foil applicator. Background Technology

[0002] Beverages are processed liquids intended for human consumption, which can be drunk directly or diluted with water in a certain proportion, such as soft drinks, juices, and tea. Beverage packaging types include bottles, cans, and bags. To prevent dust accumulation, a sheet of aluminum foil is attached to the cap after filling and sealing. Current foil-attaching mechanisms mostly rely on manual labor or robotic arms to handle the beverage cans and foil sheets for positioning, before the foil sheet is applied to the can, resulting in relatively low processing efficiency.

[0027] like Figure 1-2 As shown, the present invention provides a double-headed tin foil applicator, comprising:

[0028] Conveyor belt 1 is arranged in a horizontal direction. Side baffles 2 are provided on the front and rear sides of conveyor belt 1. The distance between the side baffles 2 matches the outer diameter of tank body 16.

[0029] The base plate 3 is located at the rear of the middle of the conveyor belt 1. The lower part of the base plate 3 is fixed to the base 8 by the column 7. A conveyor turntable 5 is provided above the base plate 3. A guide block 4 is provided on the outer side of the conveyor turntable 5. Positioning grooves 51 are uniformly machined along the circumferential direction at the edge of the conveyor turntable 5. The shape of the positioning grooves 51 matches the tank body 16. A channel for the tank body 16 to pass through is formed between the conveyor turntable 5 and the guide block 4 (see...). Figure 3The conveyor turntable 5 is arranged in a clockwise direction to form a feeding station 52, a tin foil sealing station 53, and a discharging station 54. The feeding station 52 and the discharging station 54 extend above the conveyor belt 1. The guide block 4 is fixed to the base plate 3 by bolts. The guide block 4 is machined with a guide groove 41 on the side facing the conveyor belt 1. The conveyor turntable 5 is located inside the guide groove 41. The lower center of the conveyor turntable 5 is connected to a cam divider 6. The cam divider 6 is installed on the base 8. The height of the base plate 3 is flush with the conveyor belt 1. There are two through holes 31 machined below the tin foil sealing station 53 and on the base plate 3. The lifting block 14 is slidably located in the through holes 31. The bottom of the lifting block 14 is connected to a lifting cylinder 15. The lifting cylinder 15 is installed on the base 8.

[0030] A foil sealing mechanism 10 is located above the foil sealing station 53. The foil sealing mechanism 10 includes a positioning sleeve 103. The lower part of the positioning sleeve 103 is provided with a groove 104. A vacuum suction cup 105 is embedded in the middle of the top wall of the groove 104. A heating ring 106 is provided at the edge of the top wall of the groove 104. The foil sealing mechanism 10 also includes a fixing plate 101. The upper part of the positioning sleeve 103 is connected to the fixing plate 101 through an elastic telescopic rod 102.

[0031] The tin foil storage mechanism 11 is located to the left of the tin foil sealing mechanism 10. The tin foil storage mechanism 11 includes multiple vertically arranged limiting rods 112, with a base plate 113 at the bottom of each limiting rod 112. Tin foil sheets 13 are stacked between the limiting rods 112. The tin foil storage mechanism 11 also includes a fixing plate I 111, with a through groove 1111 machined in the middle of the fixing plate I 111. The limiting rods 112 are evenly distributed along the inner edge of the through groove 1111 via mounting positioning blocks 114 (see [reference]). Figure 5 );

[0032] The foil feeding mechanism 12 is located below the foil storage mechanism 11. The foil feeding mechanism 12 includes a movable positioning plate 124, with a vacuum suction cup I 125 on its upper part. The foil feeding mechanism 12 also includes a push cylinder 123, which is connected to the rear of the positioning plate 124. The push cylinder 123 is mounted on the slider 122 and slides against the vertical plate 9 via a slide rail 121 (see [reference]). Figure 4 The slider 122 is connected to the side push cylinder 126 on the left side. The lower part of the upright plate 9 is fixed to the base 8. The fixing plate 101 and the fixing plate I111 are both fixedly installed on the upright plate 9.

[0033] This device achieves a fully automated online tin foil sealing process for the tank through the coordinated operation of a conveyor belt, conveyor turntable, tin foil storage mechanism, tin foil feeding mechanism, and tin foil sealing mechanism. It is accurate in positioning and effectively improves work efficiency.

[0034] In practical use, the invention will be described in conjunction with the accompanying drawings for ease of understanding;

[0035] Each rotation of the conveyor turntable moves one workstation. In this embodiment, each rotation of the conveyor turntable carries away two cans. During operation, the cans are arranged in a row on the conveyor belt and move from left to right. When a can moves to the left side of the conveyor turntable, as the turntable rotates, the can is embedded into the positioning groove at the edge of the conveyor turntable and moves to the base plate until the can moves below the tin foil sealing mechanism. At the same time, the tin foil feeding mechanism completes one tin foil feeding process, with the tin foil sheets stacked and placed between the limit rods. The edge of the foil sheet is limited by the bottom support plate. The initial position of the foil feeding mechanism is directly below the foil storage mechanism. The top-push cylinder drives the positioning plate to move up, and the vacuum suction cup I picks up and positions the bottom foil sheet. Then, the top-push cylinder drives the positioning plate to move down and reset. The side-push cylinder pushes the top-push cylinder and the positioning plate together to the right until they are below the foil sealing mechanism. The top-push cylinder then drives the positioning plate to move up again, and the vacuum suction cup I pulls the foil sheet into the groove at the bottom of the positioning sleeve. The vacuum suction cup inside the groove picks up and positions the foil sheet (see...). Figure 6 Vacuum suction cup I, after detaching from the tin foil, first moves downwards and then to the left to reset; the lifting cylinder drives the lifting block to lift the can upwards, and the upper part of the can extends into the groove of the positioning sleeve, with the upper part of the can contacting the tin foil (see...). Figure 7 The vacuum suction cup loosens the tin foil sheet, and then the heating ring heats the tin foil sheet. After the tin foil sheet is heated, it covers the upper part of the can. After the tin foil sealing process is completed, the lifting block drives the can to move down and reset. The can is rotated out from the bottom plate onto the conveyor belt along with the conveyor turntable. The can is then moved to the right by the conveyor belt to discharge the material.
