Abstract
Description
Technical Field
[0001] This utility model mainly relates to the field of tube conveyor technology, specifically to a tube forming pressure roller control device for a tube conveyor. Background Technology
[0002] In the tube forming process of a tube conveyor, the pressure roller, as the core component that directly acts on the tube, determines the forming quality of the tube by precisely controlling its angle and position. The pressure and contact angle requirements of the pressure roller vary significantly for tubes of different diameters and materials during the tube forming process, and need to be flexibly adjusted according to real-time processing needs.
[0003] Traditional pressure roller control devices have simple adjustment mechanisms and mostly use a single manual adjustment method. This not only makes it difficult to achieve synchronous and precise control of angle and position, but also results in low adjustment efficiency. It is difficult to adapt to the diverse needs of pipe forming processes, often leading to quality problems such as roundness deviation and surface damage in the pipes. Meanwhile, the traditional device has obvious structural defects, and the connection stability between the components is insufficient. During power transmission, lag or jamming is prone to occur. In long-term, high-frequency adjustment operations, interference between components occurs frequently, which not only affects the control accuracy but also aggravates equipment wear, shortens service life, increases maintenance costs, and affects the efficiency and stability of the pipe forming operation of the pipe conveyor. It cannot meet the needs of modern industrial production for high-precision and high-efficiency pipe forming equipment.

[0020] See attached document Figure 1-5A tube forming pressure roller control device for a tube conveyor includes a gantry frame 1, and multiple pressure roller assemblies 2 are respectively arranged inside the gantry frame 1. The multiple pressure roller assemblies 2 are distributed at the upper end and both sides of the gantry frame 1. An angle adjustment drive mechanism 3 is connected to the rear end of the pressure roller assembly 2. The pressure roller assembly 2 is connected to the gantry frame 1 through multiple adjusting screws 4. A limiting block 5 is also provided on one side of the adjusting screw 4 and is fixedly connected to the outer wall of the gantry frame 1.
[0021] The gantry frame 1 is composed of an integrally formed panel 101 and a positioning plate 102. This integral design ensures the overall structural strength and stability of the gantry frame, and can withstand various forces during the operation of the pressure roller assembly and the pipe processing. Positioning plate 102: Threaded through holes 103 are provided at the positions corresponding to multiple adjusting screws 4. The adjusting screws 4 are connected to the gantry frame 1 by threaded engagement with the threaded through holes 103, thereby providing support and adjustment basis for the position adjustment of the pressure roller assembly 2. By rotating the adjusting screws 4, the relative position of the pressure roller assembly 2 on the gantry frame 1 can be changed to adapt to the needs of different pipe diameters and different pipe forming processes. Panel 101: Each panel 101 has a clearance groove 104 corresponding to the pressure roller assembly 2, and the pressure roller assembly 2 is embedded in the clearance groove 104. The clearance groove 104 provides installation space for the pressure roller assembly 2, allowing it to be reasonably arranged inside the gantry 1. On the other hand, when the pressure roller assembly 2 is adjusted in angle or moved in position, the clearance groove 104 can prevent structural interference between the pressure roller assembly and the gantry 1, ensuring the smooth operation of the pressure roller assembly 2 and ensuring the continuity and stability of pipe processing.
[0022] The pressure roller assembly 2 is a key component that directly acts on the pipe. Its structural design and functional realization determine the quality and efficiency of pipe processing. The pressure roller assembly 2 includes a pressure roller 201, which is rotatably connected by a swing arm 202. The ends of the two swing arms 202 are connected to a bearing plate 203. The front end of the bearing plate 203 is provided with a hinge end 204 that is hinged to the swing arm 202. A rotating shaft 205 is provided between the hinge end 204 and the swing arm 202. An extension boss 206 is provided on one side of the hinge end 204, and the extension boss 206 is connected to the adjusting screw 4.
[0023] The pressure roller 201 presses and shapes the tube by rotating. During the tube forming process of the tube conveyor, the pressure roller 201 contacts the surface of the tube. As the tube moves, the pressure roller 201 rotates synchronously, providing the necessary pressure and guidance for tube forming, ensuring that parameters such as the roundness and straightness of the formed tube meet the process requirements. The pressure roller 201 is rotatably connected by a swing arm 202, which provides a movable joint for adjusting the posture of the pressure roller 201. With the swing of the swing arm 202, the pressure roller 201 can change its position. The angle and position of the swing arms 202 are adjusted to adapt to the needs of different pipe diameters and different pipe forming stages for the posture of the pressure roller. When the pipe diameter changes or when fine processing is required on different parts of the pipe, the swing arms 202 can drive the pressure roller 201 to adjust flexibly, ensuring that the pressure roller 201 always acts on the pipe with a suitable angle and pressure. The ends of the two swing arms 202 are connected to the bearing plates 203. The bearing plates 203 integrate the installation and connection of multiple functional components, providing a fixed and support base for the swing arms 202. At the same time, the front end of the bearing plates 203 is provided with a hinge end 204 that is hinged to the swing arms 202. Through the hinge structure, the swing arms 202 can rotate flexibly relative to the bearing plates 203, thereby driving the pressure roller 201 to adjust the angle. A rotating shaft 205 is provided between the hinge end 204 and the swing arms 202, providing a rotation center and support for the rotation of the swing arms 202, so that the swing arms 202 can swing flexibly around the rotating shaft 205, thereby achieving precise control of the angle of the pressure roller 201. When the angle adjustment drive mechanism 3 is operating, the linkage components 302 can adjust the angle of the swing arm 202 and the pressure roller 201 by acting on the rotating shaft 205. An extension boss 206 is provided on one side of the hinge end 204. The extension boss 206 is connected to the adjusting screw 4. When the adjusting screw 4 is rotated, the adjusting screw 4 can push or pull the pressure roller assembly 2 as a whole through the connection with the extension boss 206, so as to realize the position adjustment of the pressure roller assembly 2 on the gantry 1, thereby changing the relative position and pressure between the pressure roller 201 and the pipe to meet different pipe forming process requirements.
[0024] The angle adjustment drive mechanism 3 is the power and transmission system for achieving precise angle control of the pressure roller assembly 2. It mainly consists of a geared motor 301 and a linkage component 302. The geared motor 301 is fixed to the support plate 203, providing power output for angle adjustment. The geared motor 301 has a speed reduction and torque amplification function, converting the high-speed rotation of the motor into a low-speed, high-torque output suitable for adjusting the angle of the pressure roller assembly 2. This ensures sufficient power to smoothly drive the pressure roller assembly 2 to change its angle when adjusting the pressure roller 201, while also precisely controlling the rotation speed and angle to meet the precision requirements of different processes for pressure roller angle adjustment. The linkage component... 302 includes a synchronous belt and synchronous pulleys connected to the rotating shaft 205 and the drive end of the geared motor 301, respectively. When the geared motor 301 is running, the synchronous pulley at its drive end rotates. Through the transmission action of the synchronous belt, it drives the synchronous pulley connected to the rotating shaft 205 to rotate, thereby causing the rotating shaft 205 to rotate. Ultimately, the angle of the swing arm 202 and the pressure roller 201 is adjusted. The synchronous belt drive has the advantages of accurate transmission ratio, smooth transmission, and low noise. It can ensure the accuracy and stability of power transmission during the angle adjustment process, making the angle adjustment of the pressure roller 201 precise and controllable, and meeting the high-precision control requirements of the pressure roller angle during the tube forming process of the tube belt machine.
[0025] One end of the adjusting screw 4 is connected to the extension boss 206 of the pressure roller assembly 2, and the other end is engaged with the threaded through hole 103 of the positioning plate 102. The operator can rotate the adjusting screw 4 and use the screw transmission principle to make the adjusting screw 4 move back and forth in the threaded through hole 103, thereby pushing or pulling the pressure roller assembly 2, realizing the position adjustment of the pressure roller assembly 2 on the gantry 1. It can quickly change the relative position and pressure between the pressure roller 201 and the pipe, adapt to the processing requirements of different pipe diameters and different pipe forming stages, and at the same time, it can assist in the fine adjustment of the angle of the pressure roller assembly 2 to a certain extent. It works in conjunction with the angle adjustment drive mechanism 3 to achieve more flexible and precise pressure roller control.
[0026] A limiting block 5 is provided on one side of the adjusting screw 4 and is fixedly connected to the outer wall of the gantry frame 1. The main function of the limiting block 5 is to limit the adjustment stroke of the adjusting screw 4. When the adjusting screw 4 is rotated to move the pressure roller assembly 2, the limiting block 5 can prevent the adjusting screw 4 from moving excessively, so as to avoid the pressure roller assembly 2 from colliding or interfering with the gantry frame 1 or other components due to excessive movement of the adjusting screw 4, thus ensuring the safety and stability of the device operation. At the same time, it can also help the operator to quickly identify the adjustment limit position when adjusting the position of the pressure roller assembly 2, thereby improving the convenience and reliability of operation.
[0027] In summary, the tube forming pressure roller control device of the tube conveyor uses the gantry frame 1 as the core support. The clearance groove 104 of the panel 101 accommodates the pressure roller assembly 2, and the threaded through hole 103 of the positioning plate 102 cooperates with the adjusting screw 4. In the pressure roller assembly 2, the pressure roller 201 is connected to the bearing plate 203 via the swing arm 202. The angle adjustment is achieved by the hinge end 204 and the rotating shaft 205. The position is adjusted by the adjusting screw 4 connected to the extension boss 206. The geared motor 301 of the angle adjustment drive mechanism 3 outputs power, which is transmitted to the rotating shaft 205 through the linkage component 302. The adjusting screw 4 can flexibly change the position of the pressure roller, and the limit block 5 avoids over-adjustment. All components work together to accurately control the angle and position of the pressure roller, meet the tube forming processing requirements of the tube conveyor, and ensure the tube forming quality and stable operation of the device.
