Description

Technical Field

[0001] This utility model relates to the field of adhesive coating equipment technology, specifically an adhesive coating equipment for the production of packaging paper bags. Background Technology

[0002] Paper packaging bags are an indispensable item in our daily lives, and they are widely used in shopping, packaging, and storage.

[0003] The production of paper packaging bags typically involves steps such as gluing, sealing, and cutting. After these steps are completed, the packaging bags undergo quality inspection to ensure that each stage meets standards. Next, they are folded, packaged, and prepared for shipment to various retail outlets or direct delivery to consumers.

[0004] The applicant discovered that during the gluing process of paper packaging bags, the wound packaging paper needs to be conveyed to the gluing area first. However, as the thickness of the packaging paper on the rollers gradually changes during conveying, it alters the paper's movement path, affecting the tension of the packaging paper during gluing and consequently reducing the quality of the finished product. Therefore, we propose a gluing device for paper packaging bag production. Utility Model Content

[0005] The purpose of this invention is to provide a device that can adjust the tension of packaging paper during transportation, thereby solving the problems mentioned in the background art.

[0018] By adopting the above technical solution, it is possible to guide the packaging paper body without contacting the area to be coated with glue.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] Firstly, by setting up a packaging paper body and an adjustment component, the height of the top roller is adjusted by driving the slider through the threaded throttle in the adjustment component, thereby realizing the tension adjustment of the packaging paper body during conveying. This allows for a quick response when the thickness of the packaging paper on the roller affects the movement path of the packaging paper, avoiding the phenomenon that changes in the tension of the packaging paper affect the quality of the finished product during the glue coating process.

[0032] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below.

[0033] Please see Figure 1 , Figure 3 and Figure 5The diagram illustrates a gluing device for producing packaging paper bags, comprising a processing table 1 and a packaging paper body 101. The top of the packaging paper body 101 has a gluing area 102, which is U-shaped. A gluing assembly 2 is installed at the center of the top of the processing table 1. The gluing assembly 2 includes a drive motor 201, which is fixedly connected to the processing table 1. The output end of the drive motor 201 is connected to a rotating roller 203 via a first transmission belt 202. The wrap angle between the first transmission belt 202 and the rotating roller 203 is ≥120°. A gluing sheet 2031 is fixedly installed on the outer wall of the rotating roller 203. The perimeter of the gluing area 102 is equal to the perimeter of the gluing sheet 2031. The bottom of the gluing sheet 2031 contacts the top of the packaging paper body 101. The gluing sheet 2031 and the gluing area 102 are in contact. 2. The processing table 1 is on the same horizontal plane and has the same cross-section. A fixed seat 204 is fixedly installed on the top of the processing table 1 near the rotating roller 203. The fixed seat 204 limits the rotating roller 203. A glue-applying roller 205 is rotatably connected to the inner side of the fixed seat 204. The outer wall of the glue-applying roller 205 is in contact with the outer wall of the glue-applying sheet 2031. A glue box 206 is fixedly installed between the fixed seat 204 and the glue-applying roller 205. The glue box 206 contains glue liquid. The bottom of the glue-applying roller 205 is in contact with the glue liquid inside the glue box 206. When the packaging paper body 101 is coated with glue, the rotation of the rotating roller 203 drives the glue-applying sheet 2031 and the glue-applying roller 205 to rotate simultaneously. This causes the glue-applying roller 205 to carry out the glue liquid inside the glue box 206 and evenly apply it to the outer surface of the glue-applying sheet 2031.

[0034] When applying glue to the packaging paper body 101, the packaging paper body 101 is conveyed to the bottom of the rotating roller 203. Then, the first transmission belt 202 is started. Driven by the output shaft of the first transmission belt 202, the first transmission belt 202, the rotating roller 203, the glue coating sheet 2031 and the glue coating roller 205 are rotated synchronously. The glue coating roller 205 applies the glue liquid inside the glue box 206 to the glue coating sheet 2031. As the packaging paper body 101 comes into contact with the glue coating sheet 2031, the glue coating sheet 2031 applies the glue liquid it is attached to to the glue-to-be-glued area 102 on the top of the processing table 1, thereby completing the rapid glue application operation of the packaging paper body 101.

[0035] Please see Figures 1-4In the figure, an adjustment component 3 is installed at one end of the top of the processing table 1. The adjustment component 3 includes a mounting base 301. There are two mounting bases 301, which are fixedly installed on both sides of the top of the processing table 1. The mounting base 301 has a groove 3011 inside. A slider 302 is slidably connected inside the groove 3011. The inner sides of the two sliders 302 are rotatably connected to the top roller 303. The outer wall of the mounting base 301 has an opening on the side near the top roller 303 for the top roller 303 to move up and down. A threaded handle 304 is threadedly connected inside one of the sliders 302. One end of the threaded handle 304 passes through the interior of the mounting base 301 and is rotatably connected to the mounting base 301. Pressure rollers 305 are fixedly installed on both sides of the top of the processing table 1 near the top roller 303. The pressure rollers 305 are rotatably connected to the processing table 1. The packaging paper body 101 is wound on the pressure rollers 305 and the top roller 303.

[0036] When adjusting the tension of the packaging paper body 101, the threaded handle 304 is manually rotated, causing the slider 302 to move horizontally downward under the rotation of the threaded handle 304 and the limit of the groove 3011. This causes the packaging paper body 101 to move downward synchronously, shortening the path of the packaging paper body 101 during transportation. The pressure roller 305 smooths the top roller 303, and the threaded handle 304 in the adjustment component 3 drives the slider 302, thereby realizing the height adjustment of the top roller 303. This achieves the tension adjustment of the packaging paper body 101 during transportation, enabling a quick response when the thickness of the packaging paper on the roller affects the movement path of the packaging paper, and avoiding the phenomenon that the change in the tension of the packaging paper affects the quality of the finished product during the glue coating process.

[0037] Please see Figure 1 and Figure 5 In the figure, a guide component 4 is installed at the top of the processing table 1 away from the adjustment component 3. The guide component 4 includes a limiting seat 401. Guide rollers 402 are provided on both sides of the top of the processing table 1 near the rotating roller 203. The bottom of the guide roller 402 is in contact with the top of the packaging paper body 101. The guide roller 402 is gear-shaped. The gap between the guide rollers 402 is larger than the cross section of the U-shaped area to be glued 102. There are three guide rollers 402. Two guide rollers 402 are rotatably connected to the limiting seat 401. The other guide roller 402 is rotatably connected to the fixed seat 204. The rotating roller 203 is connected to the two guide rollers 402 through the second transmission belt 403. The wrap angle between the second transmission belt 403 and the two guide rollers 402 is ≥120°. One of the guide rollers 402 is connected to the other guide roller 402 through the third transmission belt 404. The wrap angle between the third transmission belt 404 and the other guide roller 402 is ≥120°.

[0038] When the packaging paper body 101 is conveyed, the drive motor 201 drives the rotating roller 203, and under the transmission of the second transmission belt 403 and the third transmission belt 404, the three guide rollers 402 are driven to rotate synchronously. Through the contact between the guide rollers 402 and the surface of the packaging paper body 101, the packaging paper body 101 is effectively guided before and after the glue coating. This not only realizes the basic glue coating operation of the packaging paper body 101 without consuming additional energy, but also ensures the stability of the packaging paper body 101 during the conveying stage. This saves energy and improves the energy utilization rate, thereby reducing the operating cost of the device.
