Description

Technical Field

[0001] This utility model relates to the field of production equipment, and in particular to a glue cutting device for an adhesive applicator. Background Technology

[0002] An adhesive applicator is an automated device used to apply adhesive tape to products. The tape cutting device is a component of the adhesive applicator and is usually required to cut the tape before it is applied to the product. Traditional tape applicator cutting devices lack the pressure applied to the tape during cutting, making it difficult to cut the tape quickly and efficiently due to its flexible nature. Therefore, improvements are needed. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a tape-cutting device for an adhesive applicator, comprising a frame and a unwinding reel. The unwinding reel is mounted on the frame, and a rotating shaft passes through its center. A drive motor is mounted at the end of the rotating shaft and is also mounted on the frame. A retaining plate and a cutter are symmetrically arranged diagonally below the unwinding reel. A first cylinder is mounted at the rear end of the retaining plate and is also mounted on the frame. A second cylinder is mounted at the rear end of the cutter and is also mounted on the frame. Pressing devices are provided on the left and right sides of the cutter and the retaining plate. Each pressing device includes a first fixing plate and a second fixing plate. A third cylinder is mounted on the first fixing plate, and a pressure plate is mounted at the front end of the third cylinder. Two supports are arranged parallel to each other on the second fixing plate, and rollers are mounted at the front ends of the supports. A connecting belt is provided between the two rollers.

[0004] Preferably, the front end of the pressure plate is covered with a rubber layer.

[0005] Preferably, the first and second fixing plates of the two pressing devices are arranged in opposite directions.

[0006] Preferably, the abutment plate has a cutting groove, which is configured in a V-shape.

[0007] Preferably, a length sensor is provided between the unwinding reel and the pressing device, and the length sensor is mounted on the frame.

[0008] The beneficial effects of this utility model are: the structure of this utility model is reasonable and easy to use, and it can easily and effectively press and fix the adhesive. Furthermore, it can facilitate the simple and quick cutting of the adhesive with a cutter, thus improving the efficiency of cutting the adhesive with a cutter. Attached Figure Description

[0013] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0014] Unless otherwise stated, any feature in this specification may be replaced by other equivalent or similar features. That is, unless otherwise stated, each feature is merely one example of a series of equivalent or similar features.

[0015] like Figure 1 , 2 The adhesive cutting device for an adhesive applicator shown includes a frame 1 and an unwinding reel 2. The unwinding reel 2 is mounted on the frame 1. A rotating shaft 4 passes through the center of the unwinding reel 2. A drive motor 3 is installed at the end of the rotating shaft 4 and is mounted on the frame 1. A retaining plate 7 and a cutter 9 are symmetrically arranged diagonally below the unwinding reel 2. A first cylinder 6 is installed at the rear end of the retaining plate 7 and is mounted on the frame 1. A second cylinder 8 is installed at the rear end of the cutter 9 and is mounted on the frame 1. Pressing devices are provided on the left and right sides of the cutter 9 and the retaining plate 7. The pressing devices include a first fixing plate 14 and a second fixing plate 10. A third cylinder 15 is installed on the first fixing plate 14. A pressure plate 16 is installed at the front end of the third cylinder 15. Two supports 13 are arranged parallel to each other on the second fixing plate 10. Rollers 12 are installed at the front end of the supports 13. A connecting belt 11 is provided between the two rollers 12.

[0016] The front end of the pressure plate 16 is covered with a layer of rubber.

[0017] The first fixing plate 14 and the second fixing plate 10 of the two pressing devices are set in opposite directions.

[0018] The abutment plate 7 has a cutting groove, which is configured in a V-shape.

[0019] A length sensor 5 is provided between the unwinding reel 2 and the pressing device, and the length sensor 5 is mounted on the frame 1.

[0020] During use, the adhesive roll to be unwound is installed on the unwinding reel 2. The drive motor 3 drives the rotating shaft 4 to rotate, further driving the unwinding reel 2 to unwind. During this process, the length sensor 5 will sense the length of the unwinding adhesive roll in real time. At the same time, the pressure plate 16 of the pressing device is in a state away from the adhesive, while the roller 12 and the connecting belt always remain in contact with the adhesive to make the adhesive more stable during the traction and conveying process.

[0021] When the length sensor 5 senses that the unwinding length of the adhesive has reached the preset length, the drive motor 4 will stop the unwinding of the adhesive, and the third cylinder 15 will drive the pressure plate 16 to move forward until the adhesive is pressed and fixed between the pressure plate 16 and the connecting belt 11. After the adhesive is fixed, the first cylinder 6 and the second cylinder 8 will simultaneously push the abutment plate 7 and the cutter 9 forward to approach the adhesive until the cutter 9 is inserted into the cutter groove in the abutment plate 7, thereby completing the cutting of the adhesive by the cutter 9.

[0022] The beneficial effects of this utility model are: the structure of this utility model is reasonable and easy to use, and it can easily and effectively press and fix the adhesive. Furthermore, it can facilitate the simple and quick cutting of the adhesive with a cutter, thus improving the efficiency of cutting the adhesive with a cutter.

[0023] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
