Description

Technical Field

[0001] The utility model relates to the technical field of coating mechanisms, in particular to a glue coating mechanism for grey board paper. Background Technique

[0002] Grey board paper is a kind of cardboard made from recycled waste paper and belongs to an environment-friendly packaging material. It is widely used in fields such as packaging boxes, advertising boards, file folders, photo frame backboards, luggage, hardcover books, storage boxes, samples, lining boards, puzzles, and partitions. A glue coating mechanism for grey board paper is a device specifically used to evenly coat glue on grey board paper. Through a series of carefully designed components and technological processes, this mechanism ensures the uniform distribution of glue on grey board paper, thereby improving the quality and efficiency of subsequent processes.

[0003] In the existing utility model patent "A Glue Coating Mechanism for Grey Board Paper" (Publication No.: CN220697235U), through the set hydraulic cylinder structure, its working downward pressure drives the driving roller to work in combination with the driven roller to clamp and fix the grey board paper. Subsequently, the driving roller works and rotates to convey the grey board paper forward. Due to the clamping effect of the driving roller and the driven roller, the grey board paper is not easy to slide during the conveying process. At the same time, the spring in the buffer cylinder can reduce the pressure on the grey board paper by deforming when the downward pressure applied by the driving roller is relatively large, preventing it from deforming due to excessive pressure.

[0004] In the existing device, a liquid outlet groove is set to drain the glue onto the driving roller. In the existing technical solution, there is no mechanism for closing and opening the liquid outlet groove, resulting in the continuous dripping of glue when loading and unloading grey board paper. A large amount of glue accumulates on the surface of the driving roller, causing the thickness of the next coating to become thicker, and further resulting in the problem of reduced coating quality. Therefore, a glue coating mechanism for grey board paper is needed to improve the above problems. Summary of the Utility Model

[0005] In order to solve the problem that in the existing technical solution, there is no mechanism for closing and opening the liquid outlet groove, resulting in the continuous dripping of glue when loading and unloading grey board paper, a large amount of glue accumulates on the surface of the driving roller, causing the thickness of the next coating to become thicker, and further resulting in the problem of reduced coating quality, the utility model provides a glue coating mechanism for grey board paper to solve the above problems.

A liquid outlet groove is arranged at the bottom of the storage tank, and the liquid outlet groove contacts the rubber plate.

[0015] As a preferred solution of the present utility model, a motor is installed on the side wall of one of the sliding blocks, and a driving roller is installed on the power output shaft of the motor. One end of the driving roller is rotatably arranged on the side wall of the other sliding block.

[0016] As a preferred solution of the present utility model, a scraping frame is installed between the two sliding blocks. The scraping frame is in a "U" shape, and the scraping frame is in contact with the outer wall of the driving roller.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0031] Embodiment: Please refer to Figure 1-7 A glue coating mechanism for grey board paper as shown, including a working platform 1, a control panel 2, a connecting frame 3, a hydraulic telescopic rod 4 and a coating assembly 5. A connecting frame 3 is installed on the top of the working platform 1. A hydraulic telescopic rod 4 is arranged at the central position on the top of the connecting frame 3. The telescopic shaft of the hydraulic telescopic rod 4 penetrates through the connecting frame 3 and extends to the lower part of the connecting frame 3. A coating assembly 5 for glue coating is cooperatively installed on the telescopic shaft of the hydraulic telescopic rod 4. A sealing assembly 6 is cooperatively installed with the coating assembly 5. A control panel 2 is installed on the side wall of the working platform 1;

[0032] Furthermore, the control panel 2 is used to control the start of the electrical equipment used in the device;

[0033] The coating assembly 5 includes a connection frame 501 and a storage box 508;

[0034] The sealing assembly 6 includes an insertion block 601 and an installation frame 602;

[0035] Insertion blocks 601 are respectively installed above the left and right sides of the connecting frame 3, and installation frames 602 are respectively arranged on both sides of the bottom of the storage box 508;

[0036] On one side of the inner wall of the installation frame 602, a second spring 605 is installed. The other end of the second spring 605 is installed with a moving block 604. On the lower sides of the two mutually approaching sides of the two installation frames 602, moving grooves 603 are respectively opened. A connecting rod 606 is slidably arranged in the two moving grooves 603. The two ends of the connecting rod 606 are respectively installed with moving blocks 604;

[0037] Furthermore, the connecting rod 606 slides in the moving groove 603 to limit the moving direction of the moving block 604

[0038] A closing plate 607 is installed on the side wall of the moving block 604, and a rubber plate 608 is installed on the top of the closing plate 607;

[0039] Furthermore, when the rubber plate 608 and the closing plate 607 move towards the liquid outlet groove 509, the rubber plate 608 is squeezed between the rubber plate 608 and the liquid outlet groove 509. The rubber plate 608 will undergo a certain elastic deformation and close the liquid outlet groove 509.

[0040] In this embodiment, specifically refer to Figure 1 、 Figure 3 and Figure 5 , a plug-in block 601 is slidably installed in the inner cavity of the installation frame 602, and the plug-in block 601 abuts against the moving block 604;

[0041] Furthermore, one side of the moving block 604 is designed in an arc shape, which is convenient for when the plug-in block 601 is inserted into the installation frame 602, it abuts against the moving block 604 to move;

[0042] Furthermore, when the plug-in block 601 is inserted, the moving block 604 will move towards the direction of the second spring 605. While the moving block 604 is moving, it will drive the connecting rod 606, the closing plate 607 and the rubber plate 608 to move towards the liquid outlet groove 509 and close the liquid outlet groove 509.

[0043] In this embodiment, specifically refer to Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 7 , a connecting frame 501 is installed on the telescopic shaft of the hydraulic telescopic rod 4. Symmetric sliding grooves 502 are opened at the top of the connecting frame 501. The connecting frame 501 is in an inverted "U" shape. Installation grooves 504 are respectively opened on the two inner side walls of the inner cavity of the connecting frame 501. First springs 505 are respectively installed at the top parts of the two installation grooves 504. The other ends of the two first springs 505 are respectively installed with sliding blocks 506. The two sliding blocks 506 are respectively slidably arranged in the corresponding installation grooves 504. A storage box 508 is installed at the top of the inner cavity of the connecting frame 501. A liquid outlet groove 509 is arranged at the bottom of the storage box 508. The rubber plate 608 contacts the liquid outlet groove 509;

[0044] Further, when in use, the glue is injected from the inclined opening at the top of the storage tank 508, and the glue in the storage tank 508 will flow down along the liquid outlet groove 509 onto the driving roller 503;

[0045] One side of the top of the storage tank 508 is designed with an inclined angle, which is convenient for better injection of the glue into the storage tank 508.

[0046] In this embodiment, specifically refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 7 , a motor 507 is installed on the side wall of a sliding block 506, a driving roller 503 is installed on the power output shaft of the motor 507, and one end of the driving roller 503 is rotatably arranged on the side wall of the other sliding block 506;

[0047] A scraping frame 7 is installed between the two sliding blocks 506. The scraping frame 7 is in a "U" shape, and the scraping frame 7 is in contact with the outer wall of the driving roller 503;

[0048] Further, the motor 507 drives the driving roller 503 to rotate. Since the driving roller 503 is in contact with the scraping frame 7, the scraping frame 7 will scrape the surface of the driving roller 503, achieving the benefit of evenly applying the glue on the surface of the driving roller 503.

[0049] In this embodiment, specifically refer to Figure 1 and Figure 5 , a scraping plate 10 is slidably installed in the inner cavity of the storage tank 508. The scraping plate 10 is in an overall "concave" shape, and the two protruding ends of the scraping plate 10 are respectively slidably arranged in the sliding grooves 502;

[0050] Further, pulling the scraping plate 10 to slide in the sliding groove 502, by scraping the scraping plate 10 in the storage tank 508, the benefits of accelerating the descent speed of the glue in the storage tank 508 and cleaning the residual glue on the inner wall of the storage tank 508 are achieved.

[0051] In this embodiment, specifically refer to Figure 1 and Figure 5 , the two protruding ends of the scraping plate 10 extend upward and extend above the connecting frame 501, and anti-slip lines are respectively arranged on the two protruding ends of the scraping plate 10;

[0052] Further, the design of the anti-slip lines is convenient for the staff to move the scraping plate 10 better.

[0053] In this embodiment, specifically refer to Figure 1 and Figure 2, a groove 8 is provided at the center of the top of the working platform 1, and a driven roller 9 is rotatably installed in the groove 8. The driven roller 9 and the driving roller 503 are located in the same vertical plane;

[0054] Furthermore, the cooperation between the driven roller 9 and the driving roller 503 facilitates the movement of the grey board paper.

[0055] When a grey board paper glue coating mechanism is working, first, the electrical equipment in the device is powered on;

[0056] During use, the glue is injected from the inclined opening at the top of the storage tank 508, and the glue in the storage tank 508 will flow down along the liquid outlet groove 509 onto the driving roller 503;

[0057] At the same time, the motor 507 is started to drive the driving roller 503 to rotate. Since the driving roller 503 is in contact with the scraping frame 7, the scraping frame 7 will scrape the surface of the driving roller 503, achieving the benefit of evenly coating the glue on the surface of the driving roller 503;

[0058] Furthermore, the hydraulic expansion link 4 is started to drive the entire coating assembly 5 to descend for coating. As the connecting frame 501 descends, the driving roller 503 will first come into contact with the grey board paper. During the descent of the driving roller 503, the first spring 505 and the sliding block 506 connected to the first spring 505 will play a certain buffering role for the driving roller 503, avoiding excessive extrusion of the grey board paper by the driving roller 503 and causing damage to the grey board paper;

[0059] After the coating is completed, the hydraulic expansion link 4 is used to drive the entire coating assembly 5 to move upward. At this time, the two mounting frames 602 installed on the storage tank 508 will move upward together. As the mounting frame 602 moves upward, the plug-in block 601 will be inserted into the mounting frame 602. Since the moving block 604 is arc-shaped, when the plug-in block 601 is inserted, the moving block 604 will move in the direction of the second spring 605. While the moving block 604 moves, it will drive the connecting rod 606, the closing plate 607, and the rubber plate 608 to move in the direction of the liquid outlet groove 509 and close the liquid outlet groove 509. When continued use is required, the hydraulic expansion link 4 is used to drive the coating assembly 5 to move downward, so that the plug-in block 601 moves out of the mounting frame 602. At this time, under the action of the second spring 605, the moving block 604 will drive the connecting rod 606, the closing plate 607, and the rubber plate 608 to reset, thereby opening the liquid outlet groove 509, achieving the benefit that the device can control the start and pause of the glue dripping according to needs during use;

[0060] Pull the scraping plate 10 to slide in the sliding groove 502. By scraping in the storage tank 508 with the scraping plate 10, the benefit of accelerating the descent speed of the glue in the storage tank 508 and cleaning the residual glue on the inner wall of the storage tank 508 is achieved.

[0061] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
