Description

Technical Field

[0001] This utility model relates to the field of glue machines, and in particular to a glue machine for the production of paper hooks. Background Technology

[0002] Packaging is the general term for containers, materials, and auxiliary materials used in the distribution process to protect products, facilitate storage and transportation, and promote sales, according to certain technical methods. It also refers to the operational activities involving the application of certain technical methods in the process of using containers, materials, and auxiliary materials to achieve the above objectives. As a product within the packaging field, packaging boxes have been widely used in various sectors. Different packaging boxes are suitable for different products. In certain situations, such as when exhibiting, packaging boxes often need to be hung to achieve a specific effect, thus requiring the use of hooks. Currently, the hooks used on packaging boxes are generally paper hooks, which are more environmentally friendly than plastic hooks.

[0003] Currently, in the production process of paper hooks, the sandwich bonding stage typically uses screen printing technology. This method is not only inefficient but also prone to problems such as glue overflow, false bonding, and delamination. Therefore, the application of screen printing in the sandwich bonding of paper hooks is unsatisfactory. Glue application machines, which use glue to apply adhesive, can significantly improve production efficiency. However, current glue application machines generally use very long glue rollers, which are unsuitable for paper hook production due to the relatively small area requiring glue application. Therefore, improvements are urgently needed to enhance production efficiency and product quality. Utility Model Content

[0035] The base 10 includes a base plate 11, a front shell 12, a rear shell 13, and two frame shells 14. The front shell 12 and the rear shell 13 are both disposed on the base plate 11 and arranged front to back.

The rear shell 13 is provided with a guide stop block 15 for guiding the paper hook input. The guide stop block 15 is disposed on the top surface of the rear shell 13 with its position adjustable left and right. There are two guide stop blocks 15 arranged at intervals from left to right, and the width between the two guide stop blocks 15 is adapted to the width of the paper hook. The two frame shells 14 include a fixed shell 141, a first mounting block 142, a second mounting block 143, and a third mounting block 144; the first mounting block 142 is located inside the fixed shell 141, the second mounting block 143 is located inside the fixed shell 141 and above the first mounting block 142, and the third mounting block 144 is located inside the fixed shell 141 and above the second mounting block 143.

[0036] The glue tank 20 is disposed inside the base 10; in this embodiment, the glue tank 20 is disposed on the substrate 11, and the front shell 12 covers the glue tank 20. The glue tank 20 has a square structure.

[0037] The lower rotating roller 30 is rotatably disposed within the base 10 and suspended above the glue tank 20. In this embodiment, both ends of the lower rotating roller 30 are rotatably mounted on the two frame housings 14, specifically, the end of the lower rotating roller 30 is rotatably mounted on the first mounting block 142. Furthermore, both ends of the lower rotating roller 30 are fixed to the lower gear 31, which is located within the frame housing 14.

[0038] The upper rotating roller 40 is rotatably disposed within the base 10 and located above the lower rotating roller 30. In this embodiment, the upper rotating roller 40 is located directly above the lower rotating roller 30. Both ends of the upper rotating roller 40 are rotatably mounted on the two frame housings 14, specifically, the ends of the upper rotating roller 40 are rotatably mounted on the second mounting block 143. Both ends of the upper rotating roller 40 are fixed with upper gears 41, which are located within the frame housing 14 and mesh with the lower gear 31.

[0039] The glue-applying cylinder 50 is mounted on the lower rotating roller 30 and rotates with it. The outer diameter of the glue-applying cylinder 50 is larger than that of the lower rotating roller 30, and the length of the glue-applying cylinder 50 is smaller than that of the lower rotating roller 30. Part of the glue-applying cylinder 50 extends into the glue tank 20. In this embodiment, the glue-applying cylinder 50 is detachably mounted on the lower rotating roller 30 for easy replacement as needed. Two glue-applying cylinders 50 are spaced apart along the length of the lower rotating roller 30.

[0040] The glue-applying cylinder 60 is mounted on the upper rotating roller 40 and rotates with it. The outer diameter of the glue-applying cylinder 60 is larger than that of the upper rotating roller 40, and the length of the glue-applying cylinder 60 is shorter than that of the upper rotating roller 40. The glue-applying cylinder 60 is located above the adhesive cylinder 50 and close to the dipping cylinder 50 to pick up the glue from the dipping cylinder 50. Part of the glue-applying cylinder 60 protrudes outside the machine base 10. In this embodiment, the glue-applying cylinder 60 is located directly above the dipping cylinder 50. The glue-applying cylinder 60 is also detachably mounted on the upper rotating roller 40. The length of the glue-applying cylinder 60 is the same as the length of the dipping cylinder 50, so that it can be replaced according to actual use needs. Two glue-applying cylinders 60 are spaced apart along the length of the upper rotating roller 40 to apply glue to both sides of the paper hook simultaneously.

[0041] The pressure roller 70 is mounted on the base 10, above the upper rotating roller 40. A gap 71 is formed between the pressure roller 70 and the glue-coating cylinder 60, which is adapted to the paper hook and allows the paper hook to pass through. In this embodiment, both ends of the pressure roller 70 are rotatably mounted on the two frame housings 14, specifically, the end of the pressure roller 70 is rotatably mounted on the third mounting block 144. A pinion 72 is fixed to both ends of the pressure roller 70, located inside the frame housing 14 and meshing with the upper gear 41. Two pressure rollers 70 are arranged front and rear, respectively located on the front and rear sides directly above the upper rotating roller, to better press down on the paper hook.

[0042] In addition, the second mounting block 143 is adjustable in position relative to the first mounting block 142. The first mounting block 142 is provided with a first adjusting screw 145 to control the up and down position of the second mounting block 143, so as to adjust the gap between the glue applicator 60 and the glue dipping cylinder 50. Furthermore, the third mounting block 144 is adjustable in position relative to the second mounting block 143. The top of the fixing shell 141 is provided with a second adjusting screw 146 to control the up and down position of the third mounting block 144, so as to adjust the size of the gap 71 and better adapt to paper hooks of different thicknesses.

[0043] The working principle of this embodiment is described in detail below:

[0044] First, sufficient glue is injected into the glue tank 20 so that a portion of the glue-dipping cylinder 50 remains submerged in the glue. Then, the paper hook is fed in from the rear side of the gap 71. During the feeding process, the upper surface of the paper hook comes into frictional contact with the pressure roller 70, causing the pressure roller 70 to rotate. Then, the pinion 72 drives the upper gear 41 to rotate, causing the upper rotating roller 40 to rotate. The glue-applying cylinder 60 rotates with the upper rotating roller 40. At the same time, the upper gear 41 drives the lower gear 31 to rotate, causing the lower rotating roller 30 to rotate. The glue-dipping cylinder 50 rotates synchronously with the lower rotating roller 30. Thus, both the glue-dipping cylinder 50 and the glue-applying cylinder 60 rotate synchronously. The glue-dipping cylinder 50 continuously dips into the glue tank 20, and then the glue-applying cylinder 60 dips into the glue on the glue-dipping cylinder 50. Meanwhile, the lower surface of the paper hook comes into contact with the outer surface of the glue-applying cylinder 60, thereby applying glue to the lower edge of the paper hook. After the glue application is completed, the paper hook is output along the arc-shaped guide surface 121.

[0045] The key design feature of this invention is that by setting the glue-dipping cylinder and the glue-applying cylinder on the lower rotating roller and the upper rotating roller respectively, during the production of paper hooks, only the glue-dipping cylinder and the glue-applying cylinder have glue on them, thus fixing the glue application position. This is suitable for applying glue to paper hooks, ensuring uniform glue application and preventing defects such as glue overflow or peeling, thereby reducing quality problems of paper hooks. At the same time, compared with screen printing technology, production efficiency is greatly improved, increasing efficiency by more than 10 times, bringing convenience to production operations.

[0046] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
