Abstract
Description
Technical Field
[0001] This utility model relates to the field of glue applicators, and in particular to a glue scraping device for a glue applicator. Background Technology
[0002] A glue applicator, also known as a coating machine, glue scraper, or automatic glue sprayer, is a mechanical device that evenly applies liquid glue to the surface of textiles, cardboard boxes, or leather. Glue applicators come in various forms, including drum glue applicators, double-acting glue applicators, and double-station lifting glue applicators. Furthermore, glue applicators are widely used in plywood production processes. Their working principle involves evenly applying the required amount of adhesive to both sides of dried and cut plywood cores for subsequent core arrangement and assembly. An automatic glue applicator system is a new type of mechanical system formed by combining mechanical, actuator, information processing, interface, and software components under the guidance of electronic technology, from a systems perspective. A fully automatic glue applicator consists of a mechanical system (mechanism), an electronic information processing system (computer), a power system (power source), a sensing and detection system (sensors), and an actuator system.
[0003] Existing glue applicators, when needing to control glue thickness and prevent glue overflow during subsequent bonding, require a glue scraper to spread the glue evenly. However, as the scraper moves, excess glue tends to accumulate on its surface. With continuous movement, this accumulated glue overflows onto the outside of the scraper, resulting in uneven glue width and affecting the accuracy of the application. Utility Model Content
[0004] To address the aforementioned problems, this application provides a glue scraping device for a glue applicator.
[0005] To achieve the above objectives, this application provides the following technical solution: a glue applicator scraping device, comprising a base, an X-axis slide table disposed on the base, and a Y-axis slide table mounted on the X-axis slide table. The Y-axis slide table is provided with a lifting seat that can move along the vertical direction. The bottom end of the lifting seat is provided with a scraper frame that can move synchronously with the Y-axis slide table. The front and rear sides of the scraper frame are provided with anti-overflow plates with an arc-shaped structure.
[0006] The scraper frame is equipped with a drive unit that can drive the anti-overflow plate to rotate. Both anti-overflow plates are equipped with pressure structures on the side away from the scraper frame. When the anti-overflow plate adjusts the distance between itself and the scraper frame, the pressure structures move synchronously in extension and retraction.
[0007] Furthermore, the Y-axis slide is provided with a vertically distributed electric lead screw and a limit rod distributed parallel to the electric lead screw. A drive seat is installed on the electric lead screw, and the drive seat is sleeved on the limit rod. The lifting seat is installed on the side of the drive seat away from the electric lead screw. When the drive seat moves toward the base, the lifting seat descends synchronously until the glue scraper contacts the glue.
[0008] Furthermore, the drive unit includes a guide shaft that passes through two anti-overflow plates. The guide shaft is mounted on the lifting seat, and a synchronous wheel one is provided on the part of the guide shaft located on the side of the lifting seat. The synchronous wheel one is connected to a synchronous wheel two via a synchronous belt. The synchronous wheel two is provided with a drive shaft that is coaxially distributed with it. A drive motor that can control the rotation of the drive shaft is provided on the outside of the lifting seat.
[0009] Furthermore, a limiting groove is formed on the surface of the guide shaft, and an outwardly protruding limiting block is provided on the anti-overflow plate. When the anti-overflow plate adjusts the distance between itself and the scraper, the limiting block slides inside the limiting groove.
[0010] Furthermore, the pressure structure includes an intercepting ring sleeved on the end of the guide shaft. Each intercepting ring is provided with a pressure spring on the side facing the overflow plate. Each pressure spring is provided with a pressure block on the end facing the overflow plate. The pressure block is sleeved on the guide shaft and fits against the overflow plate. When the overflow plate moves away from the scraper, the pressure block moves synchronously until the pressure spring contracts.
[0011] Furthermore, the scraper has a U-shaped structure, and both ends of the scraper have the same slope.
[0012] In summary, the technical effects and advantages of this utility model are as follows:
[0013] This invention, through the design of an anti-overflow plate, ensures that the glue accumulates on the inner side of the anti-overflow plate during the continuous movement of the glue scraper, effectively preventing uneven glue surface width caused by glue overflow and improving the accuracy of the glue scraping operation. The anti-overflow plate is rotatable, allowing the glue adhering to its surface to be scraped off, leaving the glue at the end of the glue scraper, effectively reducing glue residue and facilitating cleaning operations, thus reducing the difficulty of cleaning.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example: Reference Figure 1-6 The illustrated glue applicator includes a base 1, an X-axis slide 2 mounted on the base 1, and a Y-axis slide 3 mounted on the X-axis slide 2. The Y-axis slide 3 has a lifting seat 4 that can move vertically. In actual operation, the X-axis slide 2, carrying the Y-axis slide and the lifting seat 4, moves above the raw material. Subsequently, the lifting seat 4 descends closer to the raw material. The bottom of the lifting seat 4 has a glue scraper 5 that moves synchronously with the Y-axis slide 3. When the lifting seat 4 descends to a designated position, the glue scraper 5 contacts the glue. As the lifting seat 4 and the glue scraper 5 move synchronously with the Y-axis slide 3, the glue scraper 5 can smooth out excess glue, maintaining a smooth surface and ensuring a consistent glue thickness.
[0024] As the glue scraper 5 moves continuously, it will push the glue flat. Therefore, excess glue tends to accumulate at the end of the glue scraper 5. As the glue scraper 5 moves continuously, in order to prevent the glue accumulated at its end from moving to both sides and causing uneven glue surface width, anti-overflow plates 6 with an arc structure are provided on the front and rear sides of the glue scraper 5.
[0025] The anti-overflow plate 6 ensures that the glue accumulates inside the anti-overflow plate 6 during the continuous movement of the glue scraper 5, effectively preventing uneven glue surface width caused by glue overflow and improving the accuracy of the glue scraping operation.
[0026] After the glue scraping operation is completed, a drive unit is provided on the glue scraper 5 to rotate the glue-proof plate 6 in order to clean the glue inside the anti-overflow plate 6. At the same time, in order to completely clean the surface of the anti-overflow plate 6, the contact surface between the glue scraper 5 and the anti-overflow plate 6, and the gap between them, a pressure structure is provided on the side of both anti-overflow plates 6 away from the glue scraper 5. When the distance between the anti-overflow plate 6 and the glue scraper 5 is adjusted, the pressure structure extends and retracts synchronously.
[0027] like Figure 3 , Figure 4 As shown, the Y-axis slide 3 is equipped with a vertically distributed electric lead screw 31 and a limiting rod 33 distributed parallel to the electric lead screw 31. A drive seat 32 is mounted on the electric lead screw 31 and is sleeved on the limiting rod 33. A lifting seat 4 is installed on the side of the drive seat 32 away from the electric lead screw 31. The operation of the electric lead screw 31 can drive the drive seat 32 to move up and down. When the drive seat 32 moves towards the base 1, the lifting seat 4 connected to it descends synchronously until the glue scraper 5 comes into contact with the glue.
[0028] Specifically, such as Figure 5 , Figure 6 As shown, the drive unit includes a guide shaft 7 that passes through the two anti-overflow plates 6. The guide shaft 7 is mounted on the lifting base 4, and a synchronous roller 8 is coaxially distributed on the portion of the guide shaft 7 located on the side of the lifting base 4. The synchronous roller 8 is connected to a synchronous roller 9 via a synchronous belt 10. A drive shaft 11 is coaxially distributed on the synchronous roller 9. A drive motor 12 that can control the rotation of the drive shaft 11 is located on the outer side of the lifting base 4. Therefore, after the glue scraping operation is completed, the PLC control system controls the drive shaft 11 to rotate. Under the connection of the synchronous roller 8, the synchronous belt 10, and the synchronous roller 9, the guide shaft 7 can rotate synchronously, thereby driving the two anti-overflow plates 6 to rotate synchronously.
[0029] As the anti-overflow plate 6 rotates along the guide shaft 7, the glue adhering to its surface can be scraped off, leaving the glue at the end of the glue scraper 5, effectively reducing glue residue and facilitating cleaning operations, thus reducing the difficulty of cleaning.
[0030] Furthermore, such as Figure 5 , Figure 6 As shown, if it is necessary to control the movement of the spill guard 6 to further clean the surface of the spill guard 6, the contact surface between the scraper 5 and the spill guard 6, and the gap between them, it is necessary to control the sliding of the spill guard 6. A limiting groove 74 is formed on the surface of the guide shaft 7, and a limiting block 61 protruding outward is provided on the spill guard 6. When the distance between the spill guard 6 and the scraper 5 is adjusted, the limiting block 61 slides inside the limiting groove 74. The combination of the limiting block 61 and the limiting groove 74 allows the guide shaft 7 to smoothly drive the spill guard 6 to rotate without affecting the movement of the spill guard 6.
[0031] The pressure structure includes an intercepting ring 71 sleeved on the end of the guide shaft 7. Each intercepting ring 71 has a pressure spring 72 on the side facing the spill-proof plate 6. Each pressure spring 72 has a pressure block 73 on the end facing the spill-proof plate 6. The pressure block 73 is sleeved on the guide shaft 7 and fits snugly against the spill-proof plate 6. In its natural state, the combination of the pressure spring 72 and the pressure block 73 maintains a tight connection between the spill-proof plate 6 and the scraper 5. When the spill-proof plate 6 moves away from the scraper 5, the pressure block 73 moves synchronously until the pressure spring 72 contracts, creating a gap between the spill-proof plate 6 and the scraper 5. This allows for cleaning of the surface of the spill-proof plate 6, the contact surface between the scraper 5 and the spill-proof plate 6, and the inner side of the gap between them, improving the comprehensiveness of the cleaning work.
[0032] It is worth mentioning that the glue scraper 5 in this application has a U-shaped structure, and both ends of the glue scraper 5 have a slope structure with the same inclination. During the movement of the glue scraper 5, the slope structure can accommodate excess glue.
[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
