Description

Technical Field

[0001] This utility model relates to the technical field of label paper production equipment, specifically a tension control mechanism for label paper production. Background Technology

[0002] In the production process of label paper, tension control is one of the key factors affecting the quality of label paper. When label paper goes through multiple processes such as coating, printing, and slitting, it needs to maintain appropriate tension to ensure the flatness, dimensional accuracy and printing effect of the label paper. Therefore, it is particularly important to develop a tension control mechanism for label paper production.

[0003] A paper tension control mechanism, as described in reference announcement CN206654592U, includes a roller, a first drive shaft, a second drive shaft, a tension adjuster, a third drive shaft, a fourth drive shaft, a fifth drive shaft, a printing paper roll, a blanket, and a feed inlet. This tension control mechanism sets the roller to rotate counter-clockwise, while the second, third, fourth, and fifth drive shafts all rotate clockwise. The tension adjuster regulates the tension of the printing paper and dyed fabric, ensuring uniform tension of the printing paper and dyed fabric at the feed inlet, thus improving the overall tension of the printing paper and dyed fabric. The tape is conveyed to precisely, tightly, and smoothly overlap the printing paper and dyed fabric before being fed into the space between the roller and the tape, preventing wrinkling during the overlap. The printing paper and dyed fabric then begin the printing operation as the roller rotates. The printing is regular, the printing effect is good, the printing efficiency is high, the structure is simple, and it is convenient, quick, and practical to use. It has a high yield rate and low cost. As can be seen from the above, although this tension control mechanism can be well applied, it is usually not convenient to assist in the rolling and transfer of label paper, and therefore it is not easy to wind and store the label paper. Further improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide a tension control mechanism for label paper production, so as to solve the problem that although the tension control mechanism mentioned in the background art can be well applied, it is usually not convenient to assist in the rolling and conveying of label paper, and thus it is not easy to wind and store the label paper.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tension control mechanism for label paper production, comprising a machine base, a cabinet at the top of the machine base, take-up and untake-up rollers rotatably mounted on both sides of the cabinet surface, a first positioning frame inside the cabinet at each position of the take-up and untake-up rollers, a first motor mounted on the outer wall of the first positioning frame, one end of the first motor penetrating the first positioning frame and connected to one end of the take-up and untake-up rollers, a first guide roller rotatably mounted on the cabinet surface above one of the take-up and untake-up rollers, and a fifth guide roller rotatably mounted on the cabinet surface above the other take-up and untake-up roller. Guide rollers, and component racks are installed on the cabinet surface on one side of both the fifth guide roller and the first guide roller. A first tension roller is rotatably installed on the inner wall of the component rack. A second positioning frame is provided inside the cabinet at the position of the component rack. A second motor is installed on the outer wall of the second positioning frame. One end of the second motor is connected to one end of the first tension roller. A second tension roller is rotatably installed on the inner wall of the component rack below the first tension roller. A control panel is installed on one side of the machine table surface. The output terminal of the microcontroller inside the control panel is electrically connected to the input terminals of the first motor and the second motor, respectively.

[0006] Preferably, a third tension roller is provided above the first tension roller, and movable grooves are provided on the inner walls of the mounting frames on both sides of the third tension roller. The movable grooves allow for movable placement at both ends of the shaft.

[0007] Preferably, the third tension roller is internally connected to a shaft, and top seats are provided on both sides of the top of the mounting frame. The shaft allows for the movable placement of the third tension roller.

[0008] Preferably, both ends of the shaft pass through the movable groove and are fitted with shaft caps. The mounting bracket at the bottom of the top seat is equipped with springs to apply downward elastic pressure to the abutment.

[0009] Preferably, the end of the spring away from the top seat is equipped with an abutment, the bottom end of which contacts the top end of the shaft. By abutting the bottom end of the abutment against the top end of the shaft, the gap between the third tension roller and the first tension roller can be adaptively adjusted by the elastic pressure of the spring.

[0010] Preferably, a third guide roller is rotatably mounted at the center of the cabinet surface, and a second guide roller is rotatably mounted on the cabinet surface on one side of the third guide roller. The arrangement of the second and third guide rollers is used to guide and control the tension of the label paper.

[0011] Preferably, a fourth guide roller is rotatably mounted on the cabinet surface on the side of the third guide roller away from the second guide roller. The fourth guide roller is used to guide and control the tension of the label paper.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the tension control mechanism used in label paper production not only improves the convenience of label paper winding and unwinding, but also achieves the purpose of automatically regulating the tension of the label paper, and ensures the tension control effect of the tension control mechanism on the label paper when in use.

[0013] (1) By placing the label paper on the outer wall of the take-up and unwind roller on the left side, and inserting one end of the label paper into the guide component on the surface of the cabinet and connecting it to the outer wall of the take-up and unwind roller on the right side, when the two first motors drive the two take-up and unwind rollers to rotate clockwise, and the two second motors drive the two first tension rollers to rotate clockwise, the take-up and unwind roller on the left side will unwind the label paper, the two first tension rollers will assist in rolling and conveying the label paper, and the take-up and unwind roller on the right side will rewind the label paper, thereby improving the convenience of taking up and unwinding the label paper.

[0014] (2) The label paper is sequentially passed above the first guide roller, below the second tension roller on the left, above the first tension roller on the left, below the second guide roller, above the third guide roller, below the fourth guide roller, above the first tension roller on the right, below the second tension roller on the right, and above the fifth guide roller. When the label paper is moved from the outer wall of the left take-up roller to the outer wall of the right take-up roller, the guide component composed of the first guide roller, the second tension roller, the first tension roller, the second guide roller, the third guide roller, and the fourth guide roller can perform multiple guiding operations on the label paper, thereby achieving the purpose of automatically controlling the tension of the label paper.

[0015] (3) The two ends of the shaft are movably set inside the movable groove. Because the spring has good elasticity, it applies downward elastic pressure to the abutment, so that the abutment abuts against the top of the shaft. When the tension of the label paper increases due to speed fluctuation or thickness change, the spring is compressed and the third tension roller moves up to release the pressure. Conversely, the spring extends and the third tension roller moves down to increase the pressure, thereby maintaining the constant tension of the label paper, thus ensuring the tension control effect of the tension control mechanism on the label paper when in use.

[0027] On both sides of the surface of the cabinet 3, take-up and untake-up rollers 4 are rotatably installed. Inside the cabinet 3 at the position of the take-up and untake-up rollers 4, a first positioning frame 11 is provided. A first motor 12 is installed on the outer wall of the first positioning frame 11. One end of the first motor 12 passes through the first positioning frame 11 and is connected to one end of the take-up and untake-up rollers 4. A first guide roller 6 is rotatably installed on the surface of the cabinet 3 above one take-up and untake-up roller 4. A fifth guide roller 7 is rotatably installed on the surface of the cabinet 3 above the other take-up and untake-up roller 4. A component rack 8 is installed on the surface of the cabinet 3 on one side of the fifth guide roller 7 and the first guide roller 6. A first tension roller 15 is rotatably installed on the inner wall of the component rack 8. A third tension roller 17 is provided above the first tension roller 15. Movable grooves 20 are provided on the inner walls of the component rack 8 on both sides of the third tension roller 17.

[0028] In use, the movable groove 20 is provided to allow for movable placement at both ends of the shaft 19;

[0029] The third tension roller 17 is internally connected to a shaft 19, and top seats 21 are provided on both sides of the top of the component holder 8.

[0030] In use, the third tension roller 17 is movable by setting the shaft 19;

[0031] Both ends of the shaft 19 pass through the movable groove 20 and are fitted with shaft caps 18. Springs 22 are installed inside the mounting bracket 8 at the bottom of the top seat 21.

[0032] In use, the spring 22 is provided to apply a downward elastic pressure to the abutment 23;

[0033] A stop 23 is installed at the end of the spring 22 away from the top seat 21, and the bottom end of the stop 23 contacts the top end of the shaft 19;

[0034] In use, the bottom end of the abutment 23 abuts against the top end of the shaft 19 so that the elastic pressure of the spring 22 can adaptively adjust the distance between the third tension roller 17 and the first tension roller 15.

[0035] Inside the cabinet 3 at the position of the component rack 8, there is a second positioning frame 13. A second motor 14 is installed on the outer wall of the second positioning frame 13. One end of the second motor 14 is connected to one end of the first tension roller 15. A second tension roller 16 is rotatably installed on the inner wall of the component rack 8 below the first tension roller 15. A control panel 2 is installed on one side of the surface of the machine base 1. The output terminal of the microcontroller inside the control panel 2 is electrically connected to the input terminals of the first motor 12 and the second motor 14, respectively.

[0036] In this embodiment, the label paper is first sequentially passed above the first guide roller 6, below the second tension roller 16 on the left, above the first tension roller 15 on the left, below the second guide roller 9, above the third guide roller 10, below the fourth guide roller 5, above the first tension roller 15 on the right, below the second tension roller 16 on the right, and above the fifth guide roller 7. When the label paper is moved from the outer wall of the left take-up roller 4 and wound onto the outer wall of the right take-up roller 4, the guiding component composed of the first guide roller 6, the second tension roller 16, the first tension roller 15, the second guide roller 9, the third guide roller 10, and the fourth guide roller 5 performs multiple guiding operations on the label paper to automatically adjust the tension of the label paper. Then, the label paper is wound and placed on the outer wall of the left take-up roller 4, and one end of the label paper is passed through the guiding component on the surface of the cabinet 3 and connected to the outer wall of the right take-up roller 4. When the two first motors 12 drive the two take-up rollers 4 to rotate clockwise, When the two second motors 14 drive the two first tension rollers 15 to rotate clockwise, the left take-up and unwrap rollers 4 will unwrap the label paper, and the two first tension rollers 15 will assist in rolling and conveying the label paper. The right take-up and unwrap rollers 4 will rewind the label paper to improve the convenience of rewinding and unwinding the label paper. Finally, the two ends of the shaft 19 are movably set inside the movable groove 20. Because the spring 22 has good elasticity, it applies downward elastic pressure to the abutment 23, so that the abutment 23 abuts against the top of the shaft 19. When the tension of the label paper increases due to speed fluctuations or thickness changes, the spring 22 is compressed, and the third tension roller 17 moves upward to release the pressure. If the tension of the label paper decreases due to speed fluctuations or thickness changes, the spring 22 extends, and the third tension roller 17 moves downward to increase the pressure to maintain a constant tension of the label paper. This ensures the tension control mechanism's effect on the tension control of the label paper, thus completing the use of the tension control mechanism.
