Description

Technical Field

[0001] This utility model relates to the field of adhesive roller technology, and in particular to an adhesive roller for an adhesive applicator. Background Technology

[0002] A glue applicator, also known as a coating machine, glue scraper, or automatic glue sprayer, is a mechanical device mainly used to apply liquid glue to the surface of textiles, cardboard boxes, or leather. The glue applicator roller is a key component of the glue applicator, used to evenly spread the glue on the surface of the workpiece.

[0003] There is a glue-applying roller for a glue applicator (authorization announcement number: CN220634999U). This type of roller wears out over time, requiring regular disassembly and maintenance. Traditionally, the roller is installed using bolts at both ends. While this method provides good stability, it is cumbersome, requiring screwdrivers and other tools, and hinders quick installation and removal. Therefore, we propose this invention to solve the aforementioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a glue-applying roller for a glue applicator, which solves the aforementioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A glue-applying roller for a glue applicator includes a mounting shaft and a glue-applying roller body. The glue-applying roller body has a shaft groove. Two cylinder locking grooves are formed on the inner walls of both ends of the shaft groove. The mounting shaft has two protruding strips that are inserted into the shaft groove of the glue-applying roller body. Both ends of the mounting shaft have in-situ grooves. Two circular chambers are formed inside the mounting shaft. A locking plate is installed in each circular chamber via a spring-loaded connection mechanism. The in-situ grooves have a rotating groove and a shaft locking groove. The locking plate is rotatably inserted into the shaft locking groove. A pulling mechanism is provided on one side of the locking plate.

[0007] Preferably, the in-situ groove, the rotating groove, and the shaft locking groove are connected, and the in-situ groove and the shaft locking groove are arranged perpendicularly.

[0008] Preferably, the elastic connecting mechanism includes a circular plate, a connecting rod, and a spring. The circular plate is movably installed inside the circular chamber. One end of the connecting rod is fixedly installed on one side of the circular plate, and the other end of the connecting rod extends movably into the in-situ groove and is fixedly connected to the corresponding locking plate. One end of the spring is fixedly installed on one side of the circular plate, and the other end of the spring is fixedly installed on the inner wall of one side of the circular chamber. The elastic connecting mechanism can realize the translational position adjustment of the locking plate.

[0009] Preferably, the in-situ groove, rotating groove, and shaft locking groove are adapted to the locking plate; when the locking plate is inserted vertically into the in-situ groove, it facilitates the insertion and fitting of the glue-applying roller body into the mounting shaft; when the locking plate is inserted horizontally into the shaft locking groove and the cylinder locking groove, it achieves the locking and fixing of the glue-applying roller body onto the mounting shaft.

[0010] Preferably, the pulling mechanism includes a side plate and a U-shaped connecting plate, and two side plates are fixedly installed on one side of the locking plate, with a U-shaped connecting plate fixedly installed on each of the two side plates.

[0011] Preferably, the two side plates on the locking plate are symmetrically arranged, and the side plates and the inner wall of the U-shaped connecting plate are translatably attached to the outer wall of the mounting shaft; by pulling the U-shaped connecting plate outward, the side plates can drive the locking plate to adjust its translational position.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This glue applicator uses a glue applicator roller. After inserting the two protruding strips on the mounting shaft into the shaft groove of the glue applicator roller body, pulling the two locking plates outward causes the two sets of connecting rods and circular plates to move outward, causing the two springs to deform and compress. Then, after turning the two locking plates to ninety degrees and releasing them, the two locking plates, under the elastic force of the two springs, are inserted into the corresponding shaft locking grooves at both ends of the mounting shaft and the corresponding cylinder locking grooves in the shaft groove inside the glue applicator roller body. This achieves the fixed installation of the glue applicator roller body on the mounting shaft, enabling quick and easy installation of the glue applicator roller body. Attached Figure Description

[0020] Example: Refer to Figure 1-4 A glue-applying roller for a glue applicator includes a mounting shaft 1 and a glue-applying roller body 2. The glue-applying roller body 2 has a shaft groove 3. Two cylinder locking grooves 4 are formed on the inner walls of both ends of the shaft groove 3 on the glue-applying roller body 2. Two protruding strips 5 are provided on the mounting shaft 1. The two protruding strips 5 on the mounting shaft 1 are inserted into the shaft groove 3 of the glue-applying roller body 2. In-situ grooves 6 are formed at both ends of the mounting shaft 1. Two circular chambers 7 are formed in the mounting shaft 1. Locking plates 11 are installed in the circular chambers 7 through a spring connection mechanism. Rotary grooves 12 and shaft locking grooves 13 are formed on the in-situ grooves 6. Locking plates 11 are rotatably inserted into the shaft locking grooves 13. A pulling mechanism is provided on one side of the locking plates 11.

[0021] Furthermore, the in-situ groove 6, the rotating groove 12, and the shaft locking groove 13 are connected, with the in-situ groove 6 and the shaft locking groove 13 being arranged perpendicularly.

[0022] Furthermore, the elastic connection mechanism includes a circular plate 8, a connecting rod 9, and a spring 10. The circular plate 8 is movably installed inside the circular chamber 7. One end of the connecting rod 9 is fixedly installed on one side of the circular plate 8, and the other end of the connecting rod 9 extends movably into the in-situ groove 6 and is fixedly connected to the corresponding locking plate 11. One end of the spring 10 is fixedly installed on one side of the circular plate 8, and the other end of the spring 10 is fixedly installed on the inner wall of one side of the circular chamber 7. The elastic connection mechanism can realize the translational position adjustment of the locking plate 11.

[0023] Specifically, the in-situ groove 6, the rotating groove 12, the shaft locking groove 13 and the locking plate 11 are adapted to each other; when the locking plate 11 is inserted vertically into the in-situ groove 6, it is convenient for the glue-applying roller body 2 to be inserted into the mounting shaft 1; when the locking plate 11 is inserted horizontally into the shaft locking groove 13 and the cylinder locking groove 4, the glue-applying roller body 2 is locked and fixedly installed on the mounting shaft 1.

[0024] Furthermore, the pulling mechanism includes a side plate 14 and a U-shaped connecting plate 15. Two side plates 14 are fixedly installed on one side of the locking plate 11, and a U-shaped connecting plate 15 is fixedly installed on each of the two side plates 14.

[0025] Specifically, the two side plates 14 on the locking plate 11 are symmetrically arranged, and the side plates 14 and the inner wall of the U-shaped connecting plate 15 are translatably attached to the outer wall of the mounting shaft 1; by pulling the U-shaped connecting plate 15 outward, the side plates 14 can drive the locking plate 11 to adjust its translational position.

[0026] During use: During the installation of the glue-applying roller body 2, insert the two protruding strips 5 on the mounting shaft 1 into the shaft groove 3 of the glue-applying roller body 2. Then, the operator pulls the two U-shaped connecting plates 15 on the two locking plates 11 outwards, causing the locking plates 11 to move the connecting rod 9 and the circular plate 8 outwards. At this time, the spring 10 is compressed by force, causing the two locking plates 11 to move outwards to the corresponding rotating groove 12. Then, rotate the two locking plates 11 to ninety degrees, causing them to deflect ninety degrees. Finally, release the two locking plates 11, and the two springs... Under the elastic force of 10, the two deflected locking plates 11 are inserted into the corresponding shaft locking grooves 13 at both ends of the mounting shaft 1. At the same time, one end of the locking plate 11 is also inserted into the corresponding cylinder locking groove 4 in the shaft groove 3 inside the glue coating roller body 2. In this case, the glue coating roller body 2 can be fixedly installed on the mounting shaft 1 by adjusting the two locking plates 11 after deflection of 90 degrees. This allows for quick installation of the glue coating roller body 2, which is simple and quick to operate and avoids the need to use auxiliary tools such as screwdrivers. It is convenient to quickly install or remove the glue coating roller body 2.
