Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for paper mounting machines, and in particular to a paper tension stabilizer for paper mounting machines. Background Technology

[0002] During the operation of the paper mounting machine, the tension stability of the paper directly affects the mounting quality. If the tension is unstable, it can easily lead to paper wrinkles, shifts, or tears, affecting the product qualification rate.

[0003] However, in the existing technology, the traditional paper tension adjustment device of the mounting machine mostly adopts mechanical lever or manual adjustment method, which has problems such as low adjustment accuracy, slow response speed and poor stability. It is difficult to meet the needs of high-speed and high-precision mounting operations, and the adjustment parts are prone to loosening after long-term use, resulting in tension control failure. Utility Model Content

[0004] The purpose of this invention is to solve the problems of low precision, poor stability, and slow response of traditional paper tension adjustment devices in existing paper mounting machines, which cannot meet the requirements of high-quality paper mounting operations. Therefore, a paper tension stabilizer for paper mounting machines is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a paper tension stabilizer for a laminating machine, comprising a support roller for contacting paper, an adjustment mechanism rotatably connected to one side of the support roller, the adjustment mechanism comprising a base, an electric cylinder, a connecting end, and a positioning rod, the base being fixedly installed inside the laminating machine, the positioning rod being rotatably installed at the top of the base, the electric cylinder being fixedly installed at both ends of the positioning rod, the connecting end being fixedly installed at one end of the piston rod of the electric cylinder, and the two ends of the support roller being rotatably connected to the connecting end.

[0006] Preferably, a servo motor is fixedly installed on one side of the base, and the servo motor is located below the positioning rod.

[0007] Preferably, the output end of the servo motor is fixedly connected to a worm gear, and the worm gear is perpendicular to the positioning rod.

[0008] Preferably, a worm gear is fixedly installed on the outer wall of the positioning rod, and the worm gear is arranged in a vertical position.

[0009] Preferably, the worm gear meshes with the worm.

[0010] Preferably, the support roller, electric cylinder, and positioning rod form a rectangular frame structure, which rotates with the positioning rod as the origin during use.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, by setting an adjustment mechanism consisting of a base, an electric cylinder, a connecting end, and a positioning rod, and forming a rectangular frame structure that can rotate around the positioning rod, the precise extension and retraction of the piston rod of the electric cylinder drives the support roller to move stably, thereby achieving rapid adjustment of paper tension, improving the response speed and stability of tension control, and effectively avoiding problems such as paper wrinkling and deviation.

[0013] 2. In this utility model, by adding a servo motor, a worm gear, and a worm, the precise control characteristics of the servo motor, combined with the meshing transmission of the worm gear, enable fine adjustment of the positioning rod angle, further improving the accuracy of the support roller position adjustment. At the same time, the self-locking function of the worm gear structure can prevent the positioning rod from rotating accidentally, enhancing the reliability of the device and meeting the needs of high-speed and high-precision paper mounting operations.

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1: As Figure 1 , Figure 2 and Figure 3As shown, this utility model provides a paper tension stabilizer for a laminating machine, including a support roller 1, which is used to contact the paper. An adjustment mechanism 2 is rotatably connected to one side of the support roller 1. The adjustment mechanism 2 includes a base 21, an electric cylinder 22, a connecting end 23, and a positioning rod 24. The base 21 is fixedly installed inside the laminating machine. The positioning rod 24 is rotatably installed on the top of the base 21. The electric cylinder 22 is fixedly installed at both ends of the positioning rod 24. The connecting end 23 is fixedly installed at one end of the piston rod of the electric cylinder 22. The two ends of the support roller 1 are rotatably connected to the connecting end 23. The support roller 1, the electric cylinder 22, and the positioning rod 24 form a rectangular frame structure, which rotates with the positioning rod 24 as the origin during use.

[0021] The specific setup and function of this embodiment are described below. The support roller 1 is used to contact the paper to support and conduct the paper. The base 21 is fixedly installed inside the mounting machine, providing fixed support for the entire adjustment mechanism 2. When the paper tension needs to be adjusted, the electric cylinder 22 drives the connecting end 23 to move through the extension and retraction of the piston rod. The connecting end 23 then drives the support roller 1, which is rotatably connected to it, to move. At the same time, the rectangular frame structure composed of the support roller 1, the electric cylinder 22, and the positioning rod 24 rotates around the positioning rod 24 as the origin, changing the contact position and contact force between the support roller 1 and the paper, thereby realizing the adjustment of the paper tension. By setting up the base 21, the electric cylinder 22, the... The adjustment mechanism 2, consisting of the connecting end 23 and the positioning rod 24, forms a rectangular frame structure with the support roller 1, electric cylinder 22, and positioning rod 24 rotating around the positioning rod 24 as the origin. Combined with the precise extension and retraction of the piston rod of the electric cylinder 22, it drives the connecting end 23 and the support roller 1 to move stably, thereby precisely adjusting the contact state between the support roller 1 and the paper. This effectively ensures stable paper tension and avoids paper mounting quality problems caused by unstable tension. Meanwhile, the base 21 provides a stable installation foundation for the adjustment mechanism 2, and the rotational installation of the positioning rod 24 ensures smooth adjustment. The coordinated work of all components improves the reliability and practicality of the stabilizer, meeting the paper mounting machine's requirements for stable paper tension control.

[0022] Example 2: Figure 2 and Figure 3 As shown, a servo motor 25 is fixedly installed on one side of the base 21. The servo motor 25 is located below the positioning rod 24. The output end of the servo motor 25 is fixedly connected to a worm gear 27. The worm gear 27 is perpendicular to the positioning rod 24. A worm wheel 26 is fixedly installed on the outer wall of the positioning rod 24. The worm wheel 26 is set in a vertical state and meshes with the worm gear 27.

[0023] The overall effect of this embodiment is as follows: during operation, the servo motor 25 starts and drives the worm gear 27 to rotate. Because the worm gear 27 meshes with the worm wheel 26, the rotation of the worm gear 27 drives the worm wheel 26 to rotate. The worm wheel 26 is fixed on the positioning rod 24, which in turn drives the positioning rod 24 to rotate around the top of the base 21, thereby adjusting the angle of the positioning rod 24. Together with components such as the electric cylinder 22, the position of the support roller 1 is adjusted. By adding the servo motor 25, worm wheel 26, and worm gear 27, and utilizing the precise control characteristics of the servo motor 25, combined with the meshing transmission of the worm wheel 26 and worm gear 27, the positioning rod 24 can be precisely driven to rotate, achieving fine adjustment of the angle of the positioning rod 24. This improves the accuracy and stability of the position adjustment of the support roller 1. Furthermore, the worm wheel 26 and worm gear 27 structure has a self-locking function, which can prevent the positioning rod 24 from rotating unexpectedly due to external forces during operation, ensuring the reliability of tension adjustment. The synergy of each component enhances the control accuracy and working stability of the adjustment mechanism 2.

[0024] The device's operation and working principle are as follows: During use, the support roller 1 contacts the paper to support and conduct the paper. When paper tension needs adjustment, the electric cylinder 22 moves the connecting end 23 via the extension and retraction of its piston rod. The connecting end 23 then moves the support roller 1, which is rotatably connected to it, thus changing the contact position and contact force between the support roller 1 and the paper, achieving initial adjustment of the paper tension. For finer adjustment, the servo motor 25, fixedly mounted on one side of the base 21, is activated. The servo motor 25 drives the worm gear 2, fixedly connected to its output end. 7. Rotation: Because the worm 27 meshes with the worm wheel 26 fixedly installed on the outer wall of the positioning rod 24 in a vertical state, the rotation of the worm 27 drives the worm wheel 26 to rotate, which in turn drives the positioning rod 24 to rotate around the top of the base 21, thereby adjusting the angle of the positioning rod 24. This adjustment, together with the extension and retraction of the electric cylinder 22, adjusts the position of the support roller 1, further precisely adjusting the paper tension. Moreover, the meshing structure between the worm wheel 26 and the worm 27 has a self-locking function, which can prevent the positioning rod 24 from rotating unexpectedly due to external force during operation, ensuring stable and reliable tension adjustment.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
