Description

Technical Field

[0001] The present application relates to the technical field of scraping glue, and in particular to a paper hook automatic pre-folding box wall scraping glue and edge scraping device. Background Art

[0002] Paper boxes are a type of packaging material that is widely used in daily life. Paper boxes are favored by consumers for their lightness, aesthetics and recyclability. With the improvement of consumer awareness, consumers and product manufacturers have increasingly higher demands for the advantages of paper boxes themselves. Paper boxes usually include a box body, which is used to place products. The paper boxes are hung on display racks so that the products can be displayed and sold. In order to realize the hanging display of the box body, paper hooks are adhered to the box body, and the paper hooks are provided with through holes for the display rack to pass through. The display rack hooks the paper hooks through the through holes to realize the hanging display of the paper boxes.

[0003] The existing Chinese utility model patent with announcement number CN201559840U provides a machine-made paper box integrated portable hook, which is mainly composed of a box body, a socket and a integrated portable hook.

[0042] The specific structure of the paper box 20 and the paper hook 10 can be referred to Figure 4 and Figure 5The paper hook 10 includes a hook portion 101 and a connecting portion 102. The paper box 20 includes a paper box body 201 and a laminating paper 203. A strip hole 202 that matches the hook portion 101 is opened on one side of the paper box body 201. The laminating paper 203 is installed above the side of the paper box body 201 close to the strip hole 202. The hook portion 101 of the paper hook 10 is inserted into the strip hole 202 on the paper box body 201, and the laminating paper 203 is moved into the paper box body 201, so that the laminating paper 203 is rotated 180° so that the laminating paper 203 is in contact with the inner wall of the paper box body 201.

[0043] Reference Figure 3 and Figure 6 The clamping fixture 3 includes an upper clamping plate 31, a lower clamping plate 32, a connecting plate 33, and two connecting posts 34. The lower clamping plate 32 is fixedly mounted on the second rotating disk 22. The two connecting posts 34 are fixedly connected to the connecting plate 33. A connecting port for the connecting posts 34 is provided on the second rotating disk 22. The two connecting posts 34 pass through the connecting port and are slidably connected to the second rotating disk 22. The upper clamping plate 31 is fixedly connected to the bottom of the connecting plate 33, and the upper clamping plate 31 cooperates with the lower clamping plate 32. A connecting pipe 35 connected to the connecting port is installed below the second rotating disk 22. A spring plate 36 is provided at the bottom of the connecting post 34. An elastic spring 37 is sleeved on the connecting post 34. The two ends of the elastic spring 37 are respectively connected to the connecting pipe 35 and the spring plate 36. The elastic spring 37 is in a compressed state and can always exert a downward elastic force on the spring plate 36. Several groups of jacking components 38 for lifting the connecting columns 34 are installed on the support bracket 21. The jacking components 38 correspond one-to-one to the clamping tooling 3. The jacking components 38 include a jacking cylinder 381 and a jacking plate 382. The jacking cylinder 381 is fixedly connected to the support bracket 21, and the jacking plate 382 is fixedly connected to the piston rod of the jacking cylinder 381. The length of the jacking plate 382 is greater than the distance between the two connecting columns 34 on the corresponding connecting plate 33.

[0044] When the clamping fixture 3 moves to the position of the hopper assembly 4, the lifting cylinder 381 is activated, the piston rod of the lifting cylinder 381 extends, the lifting plate 382 moves upward, and the connecting column 34 is lifted upward, so that the upper clamping plate 31 and the lower clamping plate 32 move away from each other. At this time, the elastic spring 37 is still in a compressed state, pushing the hook part 101 of the paper hook 10 between the upper clamping plate 31 and the lower clamping plate 32. Then the piston rod of the lifting cylinder 381 is retracted, and the lifting plate 382 moves downward; under the action of gravity and the elastic spring 37, the spring plate 36, the connecting column 34 and the upper clamping plate 31 move downward, and the upper clamping plate 31 and the lower clamping plate 32 clamp the paper hook 10. The elastic spring 37 always applies a downward elastic force to the spring plate 36 to ensure the stability of the upper clamping plate 31 and the lower clamping plate 32 clamping the paper hook 10. In the above process, the upper clamping plate 31 moves up and down through the lifting and lowering movement of the connecting plate 33.

[0045] Reference Figure 3 and Figure 7 The hopper assembly 4 includes a support plate 41, a hook hopper 42 and a pushing assembly 43. The support plate 41 is located on the support bracket 21.

Adjustment is made, the pushing cylinder 431 is located between the support plate 41 and the hopper bottom plate 434, a movable plate is installed on the piston rod of the pushing cylinder 431, the movable plate is fixedly connected to the ejection bottom plate 432, and the ejection pressure plate 433 is fixedly installed on the side of the hook hopper 42 close to the second rotating disk 22, and a space is left between the ejection pressure plate 433 and the hopper bottom plate 434 for the paper supply hook 10 to pass through, and the ejection bottom plate 432 is located between the ejection pressure plate 433 and the hopper bottom plate 434, and the piston rod of the pushing cylinder 431 reciprocates, causing the ejection bottom plate 432 to reciprocate, pushing the paper hook 10 in the hook hopper 42 toward the clamping tooling 3.

[0046] A lower pressure plate 45 is also movably provided in the hook silo 42, a detection port 421 is provided on the side wall of the hook silo 42, and an identification sensor 44 is provided on the outer wall of the hook silo 42 and installed at the position of the detection port 421. When the paper hook 10 in the hook silo 42 is pushed toward the clamping tool 3, the lower pressure plate 45 applies downward pressure to the paper hook 10, so that the lowest paper hook 10 is in contact with the bottom plate 434 of the silo, thereby improving the stability of the paper hook 10 in conveying to the clamping tool 3.

[0047] During the downward movement of the lower pressure plate 45, the identification sensor 44 continues to detect. When the identification sensor 44 identifies the lower pressure plate 45, the identification sensor 44 is electrically connected to the controller. The identification sensor 44 sends a no-material signal to the controller. The controller is electrically connected to an alarm module. The alarm module can be a sound alarm or a photoelectric alarm for reminding the staff. After receiving the no-material signal, the controller sends a working signal to the alarm module to promptly remind the staff to add paper hooks 10 to the hook hopper 42.

[0049] A mounting plate 7 is provided on the support bracket 21, a moving cylinder 71 is provided on the mounting plate 7, an abutment plate 72 is installed on the moving cylinder 71, and the abutment plate 72 is provided with inclined surfaces 721 at the upper and lower ends of the side close to the second rotating disk 22, and an abutment column 56 abutting against the corresponding inclined surfaces 721 is provided on the upper movable frame 53 and the lower movable frame 54, and a support 55 is provided on the same side of the upper movable frame 53 and the lower movable frame 54, and a tension spring 57 is provided between the two supports 55, and the tension spring 57 is always in a stretched state, exerting an elastic force on the two supports 55 to move closer to each other, and the abutment plate 72 is connected to the movable rod 61 by a connecting rod 63.

[0050] When the clamping fixture 3 holding the paper hook 10 moves to the first pre-folding assembly 5, the moving cylinder 71 is started, the abutment plate 72 moves, and the moving rod 61 moves away from the clamping fixture 3. The tension spring 57 in the stretched state will move the upper moving frame 53 and the lower moving frame 54 closer to each other through the support 55. The upper moving frame 53 moves along the upper guide rail, and the lower moving frame 54 moves along the lower guide rail, so that the negative pressure head 51 is located at the upper and lower sides of the paper hook 10. At this time, the connecting part 102 of the paper hook 10 is close to the hook part 10. 1, the negative pressure head 51 is connected to the air pump through the connecting pipe, and the surface of the connecting portion 102 is adsorbed by the negative pressure head 51. Then, the moving cylinder 71 is activated, the abutment plate 72 moves, and the moving rod 61 moves toward the clamping tool 3. Under the action of the inclined surface 721, the two pillars 55 move away from each other, so that the upper movable frame 53 and the lower movable frame 54 move away from each other. At the same time, the opening member 62 is located between the two connecting portions 102 on the paper hook 10, and the two connecting portions 102 on the paper hook 10 are opened.

[0051] Reference Figure 3 The second pre-folding component 8 includes two squeezing plates 81, a driving cylinder 82, and a first bidirectional cylinder 83. The driving cylinder 82 is fixedly mounted on the supporting bracket 21. The first bidirectional cylinder 83 is fixedly connected to the piston rod end of the driving cylinder 82. The two squeezing plates 81 are respectively mounted at both ends of the first bidirectional cylinder 83. When the clamping tool 3 holding the paper hook 10 moves to the position of the second pre-folding component 8, the driving cylinder 82 is started. The two squeezing plates 81 are located between the two connecting parts 102. The first bidirectional cylinder 83 is started. The two squeezing plates 81 move away from each other. The driving cylinder 82 is started. The two squeezing plates 81 moves toward the clamping tooling 3, so that the two squeezing plates 81 are respectively located on the upper side of the upper clamping plate 31 and the lower side of the lower clamping plate 32, and the first bidirectional cylinder 83 is started. The two squeezing plates 81 approach each other, and the connecting portion 102 of the paper hook 10 is bent and stretched under the joint action of the two squeezing plates 81 and the upper clamping plate 31 and the lower clamping plate 32. Then, the driving cylinder 82 is started to move the two squeezing plates 81 away from the clamping tooling 3, and the connecting portion 102 of the paper hook 10 rebounds, so that the angle between the connecting portion 102 of the paper hook 10 and the hook portion 101 is 90°.

[0052] Reference Figure 1 and Figure 10As the second rotating disk 22 rotates, the clamping tooling 3 moves between the second pre-folding assembly 8 and the hopper assembly 4. A material picking station 12 is left between the second pre-folding assembly 8 and the hopper assembly 4. A transfer mechanism 9 is installed between the fixed bracket 1 and the supporting bracket 21.

The piston rod end of the working cylinder 93 is provided with two working plates 94 facing the upper station 12 of the first rotating disk 11. Figure 10 As shown, two working plates 94 are integrally arranged with a spaced-apart arrangement, with a friction cloth 95 wrapped around one of the working plates 94. Before the transfer mechanism 9 passes the hook portion 101 through the strip-shaped hole 202, the working cylinder 93 is activated to position the two working plates 94 outside the strip-shaped hole 202 of the carton body 201. The transfer mechanism 9 then passes the hook portion 101 of the paper hook 10 through the strip-shaped hole 202 of the carton body 201. During this process, the hook portion 101 of the paper hook 10 is inserted between the two working plates 94. Due to the contractility and friction of the friction cloth 95, after the paper hook 10 is inserted into the two working plates 94, the working cylinder 93 is activated, and the piston rod of the working cylinder 93 is retracted. The friction cloth 95 then applies force to the paper hook 10, allowing the connecting portion 102 of the paper hook 10 to better fit the glue-coated portion of the inner wall of the carton body 201, thereby ensuring the connection between the paper hook 10 and the carton body 201.

The blowing nozzle 145 faces the laminating paper 203 of the carton body 201. The pressing cylinder 143 is installed on the connecting bracket 141 and is located above the workstation 12 of the fixed bracket 1. The piston rod of the pressing cylinder 143 is fixedly connected to the scraping plate 146.

[0055] After the hook portion 101 of the paper hook 10 is inserted into the strip hole 202 of the carton body 201 through the transfer mechanism 9, the first rotating disk 11 continues to rotate, moving the carton 20 equipped with the paper hook 10 to the position of the shoveling mechanism 14, and the air blowing nozzle 145 blows air to blow the covering paper 203 on the carton body 201 toward the inside of the carton body 201, starting the shoveling cylinder 142, and the push plate 144 of the shoveling cylinder 142 pushes the covering paper 203 toward the inside of the carton body 201. Then, the downward pressure cylinder 143 is started, and the scraping plate 146 moves downward, so that the laminating paper 203 is attached to the inner wall of the carton body 201. The laminating paper 203 completely covers the connecting portion 102 of the paper hook 10. Since there is a colloidal solution between the connecting portion 102 of the paper hook 10 and the inner wall of the carton body 201, when the paper hook 10 is connected to the carton 20, the colloidal solution is easily squeezed out from between the connecting portion 102 of the paper hook 10 and the inner wall of the carton body 201, affecting product quality. By completely covering the connecting portion 102 of the paper hook 10 with the laminating paper 203, the colloidal solution is prevented from overflowing from the edge of the connecting portion 102 and causing adverse effects.

[0056] The implementation principle of the automatic pre-folding box wall scraping and edge-scraping device for paper hooks in the present application is as follows: a paper box 20 is placed on a work station 12 on a first rotating disk 11, a colloidal solution is dripped onto the inner wall of the paper box 20 by a glue-spreading and scraping mechanism 13, and the colloidal solution on the inner wall of the paper box 20 is flattened by an edge-scraping mechanism 14; when the paper hook 10 is in the hook hopper 42, the connecting portion 102 is parallel to the hook portion 101, the clamping tool 3 clamps and fixes the connecting portion 102 of the paper hook 10, and the connecting portion 102 of the paper hook 10 is fixed by the first pre-folding component 5 and the second pre-folding component 8. The paper hook 10 is bent and stretched toward the hook portion 101. Due to its resilience, the connecting portion 102 is perpendicular to the hook portion 101. A strip hole 202 is provided on the side wall of the paper box 20. The paper hook 10 is placed in the paper box 20, and the hook portion 101 is passed through the strip hole 202 of the paper box 20. The connecting portion 102 contacts the inner wall of the paper box 20. The paper hook 10 is connected to the inner wall of the paper box 20 through the colloidal solution. The covering paper 203 is attached to the inner wall of the paper box body 201 through the shoveling mechanism 14. The covering paper 203 completely covers the connecting portion 102 of the paper hook 10.

[0057] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
