Description

Technical Field

[0001] This utility model relates to the field of adhesive coating equipment technology, and in particular to an adhesive uniform applicator for a paper mounting machine. Background Technology

[0002] A laminating machine is a specialized piece of equipment used in paper processing. Its core function is to precisely bond two types of paper with different materials or properties together through processes such as gluing, laminating, and pressing, forming a composite cardboard that combines an aesthetically pleasing appearance with strong rigidity and load-bearing capacity. This provides the basic material for subsequent processes such as carton forming, gift box production, and book cover processing. Based on their level of automation, laminating machines can be divided into manual, semi-automatic, and fully automatic types. Fully automatic laminating machines are also equipped with precise positioning systems, correction devices, and quality inspection functions, effectively improving lamination accuracy and production efficiency. They are widely used in industries such as packaging printing and paper packaging.

[0003] However, existing technologies suffer from several drawbacks. First, the uniformity of adhesive application is difficult to control. Excessive adhesive in some areas can lead to paper wrinkles, adhesive overflow, and contamination of subsequent processing components. Conversely, insufficient adhesive in other areas can result in weak bonding and delamination, significantly reducing the finished product yield, increasing rework costs, and severely impacting the appearance and performance of the mounted paper. Second, the paper feeding system suffers from significant instability. Uneven pushing force and irregular rhythm during paper transport can cause paper accumulation and blockage of the channel, requiring a shutdown for cleaning before production can resume. Furthermore, missed pushing and idle running can occur, leading to material shortages on the production line. This not only disrupts the overall processing rhythm but also extends the single production cycle, significantly reducing output per unit time and failing to meet the efficiency requirements of mass production. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a uniform glue applicator for a paper mounting machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a uniform glue applicator for a paper mounting machine, comprising a fixed frame and a material frame. A rotating shaft is rotatably connected to the center of the fixed frame, and a cam is fixedly connected to the outer wall of the rotating shaft. A positioning rail is fixedly connected to the bottom end of the material frame, and a sliding seat is slidably connected inside the positioning rail. A swing rod is slidably connected to the bottom end of the sliding seat, and a fixed seat is rotatably connected to the bottom end of the swing rod. A sliding wheel is provided on the outer wall of the swing rod, and the sliding wheel is slidably connected to the outer wall of the cam. A tension spring is provided on the side wall of the swing rod, and the other end of the tension spring is fixedly connected to the positioning rail. A coating roller is provided on one side of the material frame, and a drive roller is provided between the material frame and the coating roller.

[0006] Preferably, a servo motor is fixedly connected to the outer wall of the fixed frame, and the output end of the servo motor is fixedly connected to the drive roller.

[0007] Preferably, the output end of the servo motor is provided with a transmission belt, and the servo motor is connected to the rotating shaft through the transmission belt.

[0008] Preferably, a positioning frame is fixedly connected to the outer wall of the fixing frame, the applicator roller moves under the guidance of the positioning frame, and a handle is fixedly connected to the outer wall of the applicator roller.

[0009] Preferably, the bottom end of the fixing frame is provided with a column, and the bottom end of the column is provided with a shock-absorbing pad.

[0010] Preferably, a material discharge trough is fixedly connected to the outer side wall of the fixing frame, and a storage box is provided at the bottom of the material discharge trough.

[0011] Preferably, the outer wall of the sliding seat is provided with lubricant, and the bottom end of the material frame is provided with a guide groove, and the sliding seat slides inside the guide groove.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the servo motor synchronously drives the drive roller and the rotating shaft through the transmission belt. The cam of the rotating shaft, in conjunction with the tension spring, causes the swing rod to drive the sliding seat to push the paper at a time. The paper is smoothly conveyed to the coating roller by the drive roller. The coating roller is positioned by the positioning frame. It ensures uniform coating by storing glue in the internal cavity and allowing glue to seep through the bottom fine hole. It can also be adjusted by the handle and glue can be replenished by the sealing plug. The sliding seat is lubricated to reduce resistance. The overall operation is convenient and the coating quality is guaranteed.

[0013] 2. In this utility model, the servo motor drive realizes the synchronous paper pushing, paper feeding and gluing. The sliding seat pushes the paper in a timed and quantitative manner to avoid paper accumulation or missed pushing. After gluing, the paper falls into the storage box through the feeding trough. There is no need for frequent manual material collection, which reduces manual intervention, greatly shortens the single gluing cycle, effectively improves the production efficiency of paper mounting and gluing, and is suitable for batch processing needs.

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein, and therefore the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a uniform glue applicator for a paper mounting machine, including a fixed frame 1 and a material frame 3. A rotating shaft 10 is rotatably connected to the center of the fixed frame 1. A cam 14 is fixedly connected to the outer wall of the rotating shaft 10. A positioning rail 11 is fixedly connected to the bottom end of the material frame 3. A sliding seat 12 is slidably connected inside the positioning rail 11. A swing rod 13 is slidably connected to the bottom end of the sliding seat 12. A fixed seat 15 is rotatably connected to the bottom end of the swing rod 13. A sliding wheel 18 is provided on the outer wall of the swing rod 13. The sliding wheel 18 is slidably connected to the outer wall of the cam 14. A tension spring 17 is provided on the side wall of the swing rod 13. The other end of the tension spring 17 is fixedly connected to the positioning rail 11. A coating roller 8 is provided on one side of the material frame 3. A drive roller 4 is provided between the material frame 3 and the coating roller 8.

[0019] The specific settings and functions of this embodiment are described below. Material frame 3 is a container inside the laminating machine for storing paper. Paper to be laminated is stacked inside material frame 3, and a positioning rail 11 is provided below material frame 3. A sliding seat 12 slides within the positioning rail 11 to push out the bottommost piece of paper. An opening is made on one side of material frame 3, and the thickness of the opening is slightly greater than the thickness of the paper. A protrusion is provided at the top of the sliding seat 12, allowing it to pass through the opening and contact the paper, thus pushing out the paper box drive roller 4. The drive roller 4 has two sections, upper and lower. The end of the paper is sandwiched between the two drive rollers 4, allowing the rotating drive roller 4 to further push the paper out. During the outward pushing process, the paper always contacts the coating roller 8. The bottom end is provided with fine holes for adhesive penetration, and the inside of the coating roller 8 is provided with a cavity for storing adhesive. After a period of use, the sealing plug on the outside of the coating roller 8 needs to be opened periodically, and adhesive needs to be replenished into the cavity of the coating roller 8 in a timely manner. The time interval for the sliding seat 12 to push out the paper is controlled by the rotating shaft 10. The outer periphery of the rotating shaft 10 is equipped with a cam 14, and the top of the swing rod 13 is limited by a tension spring 17, so that the sliding wheel 18 is always in contact with the outer surface of the cam 14. Every time the cam 14 rotates once, it can cause the swing rod 13 to rotate inward. The swing rod 13 drives the top sliding seat 12 to slide and push out the paper. Then the swing rod 13 rotates outward to reset, and the sliding seat 12 moves outward to prepare for the next paper to be pushed out.

[0020] Example 2: Figure 2 , Figure 3 and Figure 4 As shown, a servo motor 5 is fixedly connected to the outer wall of the fixed frame 1, and the output end of the servo motor 5 is fixedly connected to the drive roller 4. A transmission belt 6 is provided at the output end of the servo motor 5, and the servo motor 5 is connected to the rotating shaft 10 through the transmission belt 6. A positioning frame 9 is fixedly connected to the outer wall of the fixed frame 1, and the applicator roller 8 moves under the guidance of the positioning frame 9. A handle 7 is fixedly connected to the outer wall of the applicator roller 8. A column is provided at the bottom of the fixed frame 1, and a shock-absorbing pad is provided at the bottom of the column. A material discharge trough 2 is fixedly connected to the outer wall of the fixed frame 1, and a storage box is provided at the bottom of the material discharge trough 2. Lubricant is provided on the outer wall of the sliding seat 12, and a guide groove 16 is opened at the bottom of the material frame 3. The sliding seat 12 slides inside the guide groove 16.

[0021] The overall effect of this embodiment is that a servo motor 5 is set on the outside of the fixed frame 1. The servo motor 5 drives the drive roller 4 and the rotating shaft 10 to rotate simultaneously through the transmission belt 6. During the rotation of the drive roller 4, the paper sandwiched in the middle gap is pushed outward so that the paper passes evenly through the bottom surface of the coating roller 8, so that the paper and the glue seeps out of the fine holes at the bottom of the coating roller 8 and combine, thus realizing the glue application action. During the rotation of the rotating shaft 10, the swing rod 13 is driven to swing back and forth. Each swing of the swing rod 13 can push the paper at the lowest end of the material frame 3 outward once, thus realizing the effect of timed and quantitative glue application of the paper in one go.

[0022] The operating method and working principle of this device are as follows: The servo motor 5 on the outside of the fixed frame 1 drives the drive roller 4 and the rotating shaft 10 to rotate simultaneously via the transmission belt 6. The cam 14 on the outside of the rotating shaft 10 rotates accordingly. Because the top of the swing rod 13 is limited by the tension spring 17 and the positioning rail 11, the sliding wheel 18 on its outside is always in contact with the cam 14. Every time the cam 14 rotates, it drives the swing rod 13 to swing back and forth, thereby driving the sliding seat 12 to slide in the positioning rail 11 and guide groove 16 at the bottom of the material frame 3. The top protrusion of the sliding seat 12 passes through the material frame. 3. The opening contacts the paper, pushing the bottom end of the paper towards the drive roller 4; the end of the paper is clamped by the upper and lower drive rollers 4 and further pushed out, during which it contacts the coating roller 8 guided by the positioning frame 9. The coating roller 8 stores glue in the internal cavity and seeps glue through the bottom fine hole to achieve paper glue coating; after glue coating, the paper can fall into the storage box through the feeding trough 2, and the sliding seat 12 has lubricant on the outside to reduce resistance. The bottom column of the fixed frame 1 has shock-absorbing pads to buffer. After completing one timed and quantitative paper glue coating, all parts are reset, and this process is repeated to complete the paper mounting and glue coating process.

[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
