Description

Technical Field

[0001] This invention belongs to the field of pipe winding technology, and in particular relates to a pipe winding device that is resistant to pressure and tension. Background Technology

[0002] In the production line of flexible pipes such as plastic pipes and rubber pipes, winding is an important process before the finished product leaves the factory. Traditional winding equipment mostly uses mechanical tension adjustment or manual assisted sealing, which is difficult to meet the production requirements of high efficiency, no damage and automation.

[0003] Most winding equipment uses contact-type swing arms or tension rollers, which can easily scratch or locally squeeze the surface of the pipe. At the same time, after the pipe is cut to a fixed length, the existing equipment often requires a separate end sealing operation. The separation of processes leads to low efficiency, and poor sealing can easily cause gas leakage inside the pipe and end collapse, affecting product quality.

Detailed Implementation

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0031] Please see Figure 1 and Figure 2 The present invention is a pressure-resistant and tension-resistant pipe winding device, including a main frame 100. The main frame 100 includes a base frame 101 and an upper frame 102 fixedly connected to the top of the base frame 101. A mounting base plate 103 is fixedly provided on the front side of the upper frame 102, and an installation port 103a is opened on the front side of the mounting base plate 103. A winding mechanism 300 is installed on the top of the base frame 101; The front side of the mounting base plate 103 is equipped with a conveying mechanism 200 and two spaced-apart receiving roller groups 500, and the two receiving roller groups 500 are located between the conveying mechanism 200 and the winding mechanism 300. The two receiving roller groups 500 are arranged between the conveying mechanism 200 and the winding mechanism 300 mounted on the front side of the mounting base plate 103 to form a continuous support path and prevent the pipe from being locally squeezed and deformed due to gravity. Tension control mechanism 400 and sealing and cutting mechanism 600 are also installed on the front side of mounting base plate 103. Tension control mechanism 400 is disposed between conveying mechanism 200 and receiving roller group 500 away from winding mechanism 300. Sealing and cutting mechanism 600 is disposed between two receiving roller groups 500 and is accommodated in mounting opening 103a. The tension control mechanism 400 includes a fixed protective cover 401 fixedly connected to the front of the mounting base plate 103. An upper photoelectric sensor 402 and a lower photoelectric sensor 403 are fixedly installed on the front of the fixed protective cover 401 and are arranged collinearly in the vertical direction. The tube to be wound is located between the upper photoelectric sensor 402 and the lower photoelectric sensor 403. The upper photoelectric sensor 402 and the lower photoelectric sensor 403 monitor the sag of the tube in a non-contact manner and provide real-time feedback on the tension status to avoid excessive tension that could cause the tube to stretch.

[0032] Specifically, the upper photoelectric sensor 402 and the lower photoelectric sensor 403 non-contactly monitor the sag changes of the pipe and feed the real-time tension signal back to the electrical control box 700. The electrical control box 700 then adjusts the operating speed of the conveying mechanism 200 and the winding mechanism 300 to keep the pipe tension constant and avoid the pipe from stretching due to excessive tension or sagging and squeezing due to insufficient tension.

[0033] Example 1, please refer to Figures 1 to 6 The conveying mechanism 200 includes a drive shaft 201 rotatably connected inside the mounting base 103 and collinearly arranged in the vertical direction, and a protective cover 202 fixedly connected to the back of the mounting base 103. Two drive shafts 201 are respectively fitted with conveying rollers 203 and transmission gears 204. The two conveying rollers 203 are located on the front side of the mounting base plate 103, and the tube to be wound is clamped between the two conveying rollers 203. Two transmission gears 204 are located on the back of the mounting base plate 103 and inside the protective cover 202. A conveying drive motor 205 is fixedly connected to the back of the protective cover 202. A drive gear 206 is fixedly connected to the output end of the conveying drive motor 205. The drive gear 206 meshes with one of the transmission gears 204. The meshing transmission between the transmission gear 204 and the drive gear 206 causes the two conveying rollers 203 to rotate synchronously in opposite directions, so that the pipe is subjected to uniform force and the conveying speed is stable. The winding mechanism 300 includes a horizontally movable slide 301 fixedly connected to the top of the base frame 101. A column 302 is fixedly connected to the top of the movable seat of the horizontally movable slide 301. A mounting support 303 is fixedly connected to the top of the column 302. A rotating shaft 304 is rotatably connected inside the mounting support 303. A winding reel 305 is fixedly connected to one end of the rotating shaft 304. A winding wheel 306 is movably sleeved on the outside of the winding reel 305. The free end of the winding reel 305 is threaded. A locking bolt 307 is connected to fix the take-up reel 306; a take-up drive motor 308 is fixedly connected to the back of the mounting bracket 303, and the other end of the rotating shaft 304 is fixedly connected to the output end of the take-up drive motor 308. The horizontal moving slide 301 of the take-up mechanism 300 drives the take-up reel 305 to move back and forth, which cooperates with the take-up drive motor 308 to drive the take-up reel 306 to rotate, so that the pipes are neatly arranged. The locking bolt 307 facilitates quick replacement of the take-up reel 306.

[0034] In this embodiment, the vertical sag of the pipe is monitored non-contactly by the upper photoelectric sensor 402 and the lower photoelectric sensor 403. When the pipe sags due to gravity and blocks the lower photoelectric sensor 403, the electrical control box 700 determines that the tension is too low and immediately increases the winding speed or decreases the conveying speed. When the pipe floats upward due to excessive tension and blocks the upper photoelectric sensor 402, the electrical control box 700 determines that the tension is too high and immediately decreases the winding speed or increases the conveying speed. When the pipe is between the two sensors, the tension is normal, and the electrical control box 700 dynamically adjusts the conveying mechanism 200. The operating speed of the winding mechanism 300 keeps the pipe tension constant, preventing excessive tension from causing stretching or insufficient tension from causing sagging and compression. At the same time, the conveying drive motor 205 drives the drive gear 206 to mesh with the transmission gear 204, driving the two conveying rollers 203 to rotate synchronously in opposite directions to stably convey the pipe. The winding drive motor 308 drives the winding wheel 306 to rotate, which, together with the horizontal moving slide 301, drives the winding shaft 305 to move back and forth, so that the pipe is subjected to uniform force and neatly arranged during the winding process, effectively preventing local compression and stretching deformation. In addition, the locking bolt 307 facilitates quick replacement of the winding wheel 306.

[0035] Example 2, please refer to Figure 3 , Figure 7 , Figure 8 , Figure 9 and Figure 10 Based on the first specific embodiment, the receiving roller assembly 500 includes a fixed base plate 501 fixedly connected to the front of the mounting base plate 103. Two fixed rotating shafts 502 are fixedly connected to the front of the fixed base plate 501. Receiving wheels 503 are rotatably connected to the outside of the two fixed rotating shafts 502 respectively, and the tube to be wound is passed between the two receiving wheels 503. The sealing and cutting mechanism 600 includes a back plate bracket 608 fixedly connected to the back of the mounting base plate 103 and two movable brackets 602 located inside the mounting opening 103a and arranged symmetrically in the upper and lower parts. The backplate bracket 608 is internally fixedly connected to a moving mechanism 601 for driving two moving brackets 602 to move in opposite directions. Two parallel mounting crossbars 604 are respectively installed on the opposite side of the two moving brackets 602. Heating sealing plates 605 for heating and welding pipes are respectively fixedly installed on the opposite side of the two vertically opposite mounting crossbars 604. The moving mechanism 601 drives the two moving brackets 602 to move in opposite directions synchronously, causing the heating sealing plates 605 on the mounting crossbars 604 to press against each other, which can quickly complete the heat sealing of the pipe ends. Two movable supports 602 are fixedly connected to the opposite sides of a cutter holder 606. A cutting blade 607 is detachably installed inside each of the two cutter holders 606. The cutting blade 607 inside the cutter holder 606 is detachable for easy replacement or sharpening. Cutting and sealing are integrated into the same mechanism, and the action is smooth and efficient. Four buffer damping rods 603 are respectively installed on the opposite side of the two movable supports 602; The buffer damping rod 603 includes an outer sleeve 603a fixedly connected to the corresponding movable bracket 602. A movable rod 603b is movably sleeved inside the outer sleeve 603a. A buffer spring 603c is installed inside the outer sleeve 603a and is located between the movable rod 603b and the corresponding movable bracket 602. A mounting crossbar 604 is fixedly connected to the free end of the corresponding movable rod 603b. The buffer spring 603c inside the outer sleeve 603a of the buffer damping rod 603 is compressed when pressed to form an elastic buffer. The moving mechanism 601 includes a guide slide plate 601a fixedly connected inside the back plate bracket 608. Two opposing racks 601b are slidably connected to the inner walls of the guide slide plate 601a. ​​Sliding seats 601c are fixedly connected to the opposite sides of the two racks 601b. The moving bracket 602 is fixedly connected to the outside of the corresponding sliding seats 601c. A moving drive motor 601d is fixedly connected to the center of the back of the guide slide plate 601a. ​​A connecting gear 601e is fixedly connected to the output end of the moving drive motor 601d. Both racks 601b mesh with the connecting gear 601e. A fixing bracket 104 is also fixedly connected to the front side of the mounting base plate 103. A pipeline length detector 800 for detecting the moving length of the pipe is fixedly installed on the outside of the fixing bracket 104. The pipeline length detector 800 on the fixing bracket 104 detects the conveying length of the pipe in real time, so as to realize fixed-length winding and fixed-length cutting. Two electronic clamps 900 for clamping and fixing the cut tube are also fixedly connected to the front side of the mounting base plate 103. The two electronic clamps 900 are located on both sides of the sealing and cutting mechanism 600. The two electronic clamps 900 clamp the tube to prevent the tube from springing back or shifting after cutting. An electrical control box 700 is installed inside the base frame 101. The electrical control box 700 is electrically connected to the conveying mechanism 200, the winding mechanism 300, the tension control mechanism 400, the sealing and cutting mechanism 600, and two electronic clamps 900, respectively, and is used to control the timing and coordinated operation of the pipe conveying, tension adjustment, winding, cutting and sealing and clamping actions.

[0036] In this embodiment, the pipe conveying length is detected in real time by the pipe length detector 800 on the fixed bracket 104 and fed back to the electrical control box 700. When the cumulative length reaches the preset value, the electrical control box 700 pauses the conveying mechanism 200, starts the two electronic clamps 900 on both sides of the sealing and cutting mechanism 600 to clamp the pipe respectively, and then controls the moving mechanism 601 to drive the two moving brackets 602 to move towards each other: the moving drive motor 601d drives the connecting gear 601e to rotate, and the connecting gear 601e simultaneously drives the two racks 601b to slide in the opposite direction along the guide slide plate 601a. ​​The racks 601b are driven by the sliding seat 601c. The two movable supports 602 move towards each other, causing the upper and lower opposing heating sealing plates 605 to press together to complete the heat sealing, preventing gas leakage into the pipe and keeping the pipe full. Then, the cutting blade 607 in the cutter seat 606 cuts the pipe. The buffer springs 603c in the four buffer damping rods 603 on each movable support 602 are compressed when they close to form an elastic buffer, avoiding rigid impact. The two receiving roller groups 500 form a continuous support path between the conveying mechanism 200 and the winding mechanism 300, preventing the pipe from being locally squeezed and deformed due to gravity. This allows for the rapid completion of fixed-length cutting and sealing, improving work efficiency and sealing quality.
