Description

Technical Field

[0001] This invention relates to the field of composite material processing equipment technology, and in particular to a composite material winding device. Background Technology

[0002] Fiber-reinforced resin matrix composites possess characteristics such as high specific strength, high specific stiffness, light weight, and corrosion resistance, and their excellent performance in reducing product weight has led to their widespread application in aerospace, shipbuilding, and automotive industries. However, high manufacturing costs and long processing times reduce the processing efficiency of composite materials. Therefore, composite winding mechanisms with lap splicing and tension adaptive adjustment functions have shown significant engineering application value.

[0003] Chinese Patent Application No. 201210282693.9 discloses a thermoplastic composite material winding device. The steps of using the thermoplastic winding device of this invention are as follows: First, the composite fiber pre-impregnated material on the yarn frame is pulled onto the mandrel and fixed via a yarn guide plate. A certain tension is controlled according to the process, displayed and adjusted by a tension meter. Then, external heater A12, infrared heater B13, and infrared heater C14 are turned on. Infrared heaters A12 and B13 are used to heat and melt the pre-impregnated material, while infrared heater C14 is used to heat the mandrel, causing the pre-impregnated material wound on the surface of the mandrel to melt. This allows for better bonding between the pre-impregnated material melted by infrared heaters A12 and B13 and the pre-impregnated material substrate melted by infrared heater C14, resulting in a high-quality wound product. Because thermoplastic resin cools and cures quickly, the heat-insulating head can reduce the temperature loss of the molten pre-impregnated material. Then, the winding angle and winding trajectory of the entire winding process are controlled by program-controlled mandrel speed, trolley speed 1, and drum rotation angle. Gears, servo motors, and rolling bearings a7 and b8 are used to control and drive the rotation of the drum. This winding equipment is suitable for composite fiber pre-impregnated materials.

[0004] Regarding the aforementioned technologies, when using this thermoplastic composite winding equipment, a tension meter is used to display and adjust the tension of the output material. The tension meter is an instrument that measures the magnitude of the mutual traction force between the inside of the wire mesh and the contact body of the fixed wire mesh when the wire mesh is subjected to tension. However, since the composite material is a strip material, the tension meter cannot adjust the tension of the output material, which ultimately leads to a reduction in the winding quality of the composite material. Summary of the Invention

[0005] To address the aforementioned technical problems, the present invention provides a composite material winding device, comprising:

[0006] Support frame.

[0007] The feeding roller, rotatably connected to the support frame, is used to hold the material roll for discharge.

[0008] The tension roller is rotatably connected to the support frame and is located on one side of the feeding roller.

[0009] The first guide roller is rotatably connected to the support frame and is located between the feed roller and the tension roller.

[0010] The second guide roller, rotatably linked to the support frame, is positioned on both sides of the tension roller, along with the first guide roller, and is used to press the material roll onto the surface of the tension roller.

[0011] The first magnetic powder brake has its output shaft fixedly connected to the tension roller on the same axis. By controlling the torque of the tension roller, the tension of the material belt can be adjusted.

[0012] To achieve the above objectives, the present invention is implemented through the following technical solution: the material roll is coaxially fixed to the unloading roller, so that the material strip of the material roll is pulled out and successively passes around the first guide roller away from the tension roller, passes around the tension roller away from the first guide roller, passes around the second guide roller away from the tension roller, and finally pulls out the material strip for winding. The first guide roller and the second guide roller are set on both sides of the tension roller, pressing the material strip of the material roll onto the surface of the tension roller. During the output of the material strip, the torque of the tension roller rotation is controlled by a magnetic powder brake, thereby adjusting the tension of the output material strip.

[0013] Compared with the prior art, the present invention has the following advantages: the contact area between the tension roller and the surface of the material strip is large; the torque of the tension roller is controlled by the magnetic powder brake; the tension roller is pulled by the friction force of the tension roller on the surface of the material strip, thereby controlling the tension of the material strip, accurately adjusting the tension of the output material, and improving the winding quality of composite materials.

[0014] A further preferred embodiment includes:

[0015] The support base is slidably connected to the support frame.

[0016] The third guide roller is rotatably connected to the support base and is located on the side of the second guide roller away from the tension roller.

[0017] The fourth guide roller, rotatably connected to the support frame, is used to press the material roll onto the surface of the third guide roller.

[0018] The pressure sensor, connected to the support base on one side and the support frame on the other side, is used to detect the pressure of the material strip on the surface of the third guide roller. It is electrically connected to the first magnetic powder brake, thereby adjusting the output torque of the first magnetic powder brake by the pressure of the material strip on the surface of the third guide roller.

[0019] Using the above technical solution, after the material strip is output from the second guide roller, it passes around the third guide roller away from the second guide roller, then passes around the fourth guide roller away from the second guide roller, and is then pulled out for winding. The second and fourth guide rollers are set on both sides of the tension roller, pressing the material strip of the coil onto the surface of the third guide roller. When the tension of the material strip increases or decreases, the tension of the material strip is transmitted to the surface of the third guide roller, generating pressure on the third guide rail. The third guide roller drives the support seat to slide relative to the support frame. The support frame transmits the tension of the material strip to the pressure sensor. The pressure sensor controls the first magnetic powder brake to adjust the torque of the pressure roller rotation based on the change in the material strip tension, thereby controlling the tension of the material strip in real time according to the change in the material strip tension, so that the tension of the material strip is kept in a stable state.

[0020] A further preferred embodiment includes:

[0021] The second magnetic powder controller has its output shaft fixedly connected to the feeding roller on the same axis, and is used to adjust the torque of the feeding roller.

[0022] Using the above technical solution, the second magnetic powder controller controls the tension of the material belt by controlling the torque of the feeding roller, and works in conjunction with the first magnetic powder brake to control the tension of the material belt winding as a whole.

[0023] A further preferred embodiment includes:

[0024] The lower heating plate is fixedly installed on the support frame.

[0025] The upper heating plate is movably connected to the support frame and is used to work with the lower heating plate to heat the material strip joints, thereby heating and connecting the two material strip joints.

[0026] Using the above technical solution, when the material roll is used up, a new material roll is replaced, and the joint of the two material rolls is placed between the lower heating plate and the upper heating plate. The upper heating plate and the lower heating plate are used to clamp and heat the material rolls, thus thermally connecting the two material rolls and improving work efficiency.

[0027] A further preferred embodiment includes:

[0028] The discharge rack is slidably connected to the support frame.

[0029] The discharge roller is rotatably connected to the discharge frame and is used to support the material belt.

[0030] The driving component is connected to the discharge rack and is used to drive the discharge rack to slide, thereby moving the discharge roller and changing the position of the material belt discharge.

[0031] Using the above technical solution, the drive component drives the discharge frame to move, the discharge frame slides and drives the discharge roller to move, and the discharge roller pushes the material belt to move, thereby changing the discharge position.

[0032] A further preferred embodiment includes:

[0033] The first rotating ring has its inner hole rotatably connected to the first guide roller, and its outer ring is rotatably connected to the support frame.

[0034] The first magnetic block is slidably connected to the first rotating ring, and the sliding direction is along the radial direction of the first rotating ring, and it contacts and cooperates with the support frame.

[0035] The first elastic element has one end connected to the first rotating ring and the other end connected to the first magnetic block, and is used to apply force to the first magnetic block so that the first magnetic block abuts against the support frame.

[0036] The second magnetic block is slidably connected to the support frame, and its sliding direction is along the axis of the first rotating ring. It is used to apply an attractive force to the first magnetic block so that the first magnetic block is separated from the support frame.

[0037] The second rotating ring has its inner hole rotatably connected to the second guide roller, and its outer ring is rotatably connected to the support frame.

[0038] The third magnetic block is slidably connected to the second rotating ring, with the sliding direction along the radial direction of the second rotating ring, and it contacts and engages with the support frame.

[0039] The second elastic element is connected at one end to the second rotating ring and at the other end to the third magnetic block. It is used to apply force to the second magnetic block so that the third magnetic block abuts against the support frame.

[0040] The fourth magnetic block is slidably connected to the support frame, and its sliding direction is along the axis of the second rotating ring. It is used to apply attraction to the third magnetic block so that the third magnetic block is separated from the support frame and fixedly connected to the second magnetic block.

[0041] The third rotating ring has its inner hole rotatably connected to the fourth guide roller, and its outer ring is rotatably connected to the support frame.

[0042] The fifth magnetic block is slidably connected to the third rotating ring, and the sliding direction is radial along the third rotating ring (25), and it contacts and cooperates with the support frame.

[0043] The third elastic element is connected at one end to the third rotating ring and at the other end to the fifth magnetic block. It is used to apply force to the fifth magnetic block so that the fifth magnetic block abuts against the support frame.

[0044] The sixth magnetic block is slidably connected to the support frame, and its sliding direction is along the axis of the third rotating ring. It is used to apply attraction to the fifth magnetic block so that the fifth magnetic block can be separated from the support frame.

[0045] A driving device is connected to the second magnetic block to drive it to slide. It is also connected to the fourth magnetic block to drive it to slide. Finally, it is connected to the sixth magnetic block to drive it to slide.

[0046] Using the above technical solution, after prolonged use, the frictional force between the first guide roller, the second guide roller, and the fourth guide roller and the support frame will gradually increase. Therefore, the rotational speed of the first guide roller will differ from that of the second and fourth guide rollers, causing friction in the material belt. At this time, the driving device drives the second magnetic block to move. The second magnetic block moves into the inner hole of the first rotating ring. Under the attraction of the second magnetic block, the first magnetic block moves, the first elastic element deforms, and the first magnetic block separates from the support frame. The first rotating ring can then rotate relative to the support frame, thereby reducing the frictional force between the first guide roller and the support frame. The driving device then drives the fourth magnetic block to move. The fourth magnetic block moves into the inner hole of the third rotating ring. Under the attraction of the fourth magnetic block, the third magnetic block moves, the second elastic element deforms, and the third magnetic block separates from the support frame. The second rotating ring can then rotate relative to the support frame, thereby reducing the frictional force between the second guide roller and the support frame. The drive device drives the sixth magnetic block to move. The sixth magnetic block moves into the inner hole of the third rotating ring. The fifth magnetic block moves under the attraction of the sixth magnetic block. The third elastic element deforms and the fifth magnetic block separates from the support frame. The third rotating ring can rotate relative to the support frame, thereby reducing the friction between the fourth guide roller and the support frame. Finally, the rotation speed of the first guide roller is the same as the rotation speed of the second guide roller and the fourth guide roller, avoiding wear on the material belt due to different rotation speeds.

[0047] More preferably, the driving device includes:

[0048] The pusher blocks are fixedly connected to the second magnetic block, the fourth magnetic block, and the sixth magnetic block, respectively.

[0049] The fourth elastic element is connected to the push block at one end and to the support frame at the other end. It is used to apply force to the support frame so that the push block moves closer to the first rotating ring, the second rotating ring, and the third rotating ring.

[0050] The limit block is fixedly connected to the push block.

[0051] The stop block abuts against the push block and slides with the support frame, with the sliding direction being different from the sliding direction between the push block and the support frame.

[0052] The drive component, connected to the stop drive, is used to drive the stop to slide.

[0053] Using the above technical solution, when the limiting block and the stop block abut, the second magnetic block moves away from the first magnetic block, the fourth magnetic block moves away from the third magnetic block, the sixth magnetic block moves away from the fifth magnetic block, the fourth elastic element is in a deformed state, the driving component drives the stop block to slide, the stop block separates from the push block, the fourth elastic element applies force to the push block, the fourth elastic element drives the push block to move, and the push block drives the second magnetic block to move, the fourth magnetic block to move, and the sixth magnetic block to move.

[0054] More preferably, the driving component includes:

[0055] The first pulley is coaxially and fixedly connected to the fourth guide roller.

[0056] The second pulley is coaxially and fixedly connected to the second guide roller.

[0057] The third pulley is coaxially and fixedly connected to the first guide roller.

[0058] The fourth pulley is rotatably connected to the support frame and is located on the side of the third pulley away from the second pulley.

[0059] The fifth pulley is rotatably connected to the stop block and is located on the side of the first pulley away from the second pulley.

[0060] The transmission belt has one end connected to the fourth pulley and the other end connected to the fifth pulley. The first pulley, the second pulley, and the third pulley are located between the two ends of the transmission belt, and successively contact one side of the belt body and separate from the other side of the belt body.

[0061] The fifth elastic element, with one end connected to the stop block and the other end connected to the support frame, is used to apply force to the stop block, causing the fifth pulley to move away from the fourth pulley.

[0062] Using the above technical solution, during the material conveyor belt discharge process, the belt drives the first, second, and third pulleys to rotate. When the speed of the first pulley is less than that of the second pulley, the length of the transmission belt between the first and second pulleys increases. The transmission belt pulls the fifth pulley, causing the fifth elastic element to deform. The fifth pulley then moves the stop block, making the speed of the first pulley equal to that of the second pulley, thus avoiding wear on the belt due to the difference in speed. When the speed of the first pulley is greater than that of the second pulley, the first pulley pulls the second rotating pulley through the transmission belt, making the speed of the first pulley equal to that of the second pulley, thus avoiding wear on the belt due to the difference in speed. Similarly, the speeds of the second and third pulleys can be kept the same, and the speeds of the first and third pulleys can also be kept the same, ultimately making the speeds of the first, second, and third pulleys equal.

[0063] A further preferred embodiment is that the transmission belt is a synchronous belt, the first pulley is a synchronous pulley, the second pulley is a synchronous pulley, the third pulley is a synchronous pulley, the fourth pulley is a synchronous pulley, and the fifth pulley is a synchronous pulley.

[0064] By adopting the above technical solution, there will be no slippage between the synchronous belt and the synchronous pulley, further ensuring that the speeds of the first pulley, the second pulley, and the third pulley are the same.

[0065] A further preferred embodiment is that the lower heating plate and the upper heating plate are hinged together.

[0066] In summary, compared with the prior art, the present invention has the following advantages: The material roll is coaxially fixed to the unloading roller, allowing the material strip to be pulled out sequentially, passing over the first guide roller away from the tension roller, then around the tension roller away from the first guide roller, then around the second guide roller away from the tension roller, and finally pulled out for winding. The first and second guide rollers are positioned on both sides of the tension roller, pressing the material strip of the roll against the surface of the tension roller. During the material strip output process, the torque of the tension roller's rotation is controlled by a magnetic powder brake, thereby adjusting the tension of the output material strip. The tension roller has a large contact area with the material strip surface. By controlling the torque of the tension roller through the magnetic powder brake, and through the frictional force of the tension roller on the material strip surface, the tension roller is pulled, thereby controlling the tension of the material strip, accurately adjusting the output tension, and improving the winding quality of the composite material.

Detailed Implementation

[0077] The following is in conjunction with the appendix Figure 1-9 The present invention will be described in further detail below.

[0078] Fiber-reinforced resin matrix composites possess characteristics such as high specific strength, high specific stiffness, light weight, and corrosion resistance, and their excellent performance in reducing product weight has led to their widespread application in aerospace, shipbuilding, and automotive industries. However, high manufacturing costs and long processing times reduce the processing efficiency of composite materials. Therefore, composite winding mechanisms with lap splicing and tension adaptive adjustment functions have shown significant engineering application value.

[0079] Chinese Patent Application No. 201210282693.9 discloses a thermoplastic composite material winding device. The steps of using the thermoplastic winding device of this invention are as follows: First, the composite fiber pre-impregnated material on the yarn frame is pulled onto the mandrel and fixed via a yarn guide plate. A certain tension is controlled according to the process, displayed and adjusted by a tension meter. Then, external heater A12, infrared heater B13, and infrared heater C14 are turned on. Infrared heaters A12 and B13 are used to heat and melt the pre-impregnated material, while infrared heater C14 is used to heat the mandrel, causing the pre-impregnated material wound on the surface of the mandrel to melt. This allows for better bonding between the pre-impregnated material melted by infrared heaters A12 and B13 and the pre-impregnated material substrate melted by infrared heater C14, resulting in a high-quality wound product. Because thermoplastic resin cools and cures quickly, the heat-insulating head can reduce the temperature loss of the molten pre-impregnated material. Then, the winding angle and winding trajectory of the entire winding process are controlled by program-controlled mandrel speed, trolley speed 1, and drum rotation angle. Gears, servo motors, and rolling bearings a7 and b8 are used to control and drive the rotation of the drum. This winding equipment is suitable for composite fiber pre-impregnated materials.

[0080] Regarding the aforementioned technologies, when using this thermoplastic composite winding equipment, a tension meter is used to display and adjust the tension of the output material. The tension meter is an instrument that measures the magnitude of the mutual traction force between the inside of the wire mesh and the contact body of the fixed wire mesh when the wire mesh is subjected to tension. However, since the composite material is a strip material, the tension meter cannot adjust the tension of the output material, which ultimately leads to a reduction in the winding quality of the composite material.

[0081] Based on the above-mentioned technical problems, the applicant has conceived the following technical solutions:

[0082] When the belt drives the tension roller to roll, the torque of the tension roller is controlled by the magnetic powder brake, thereby controlling the tension of the belt.

[0083] Based on the above concept, the applicant has proposed the technical solution of this application, as follows:

[0084] A composite material winding device, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 as well as Figure 9As shown, it includes: a support frame 1; a feeding roller 2, rotatably connected to the support frame 1, used to hold the material roll 41 for discharge; a tension roller 3, rotatably connected to the support frame 1, located on one side of the feeding roller 2; a first guide roller 4, rotatably connected to the support frame 1, located between the feeding roller 2 and the tension roller 3; a second guide roller 5, rotatably connected to the support frame 1, and located on both sides of the tension roller 3, respectively, used to press the material strip 40 of the material roll 41 onto the surface of the tension roller 3; and a first magnetic powder brake 6, whose output shaft is coaxially fixedly connected to the tension roller 3, and which adjusts the tension of the material strip 40 by controlling the torque of the tension roller 3.

[0085] To achieve the above objectives, the present invention is implemented through the following technical solution: A material roll 41 is coaxially fixed to the unloading roller 2, causing the material strip 40 of the material roll 41 to be pulled out sequentially around the first guide roller 4 on the side away from the tension roller 3, around the tension roller 3 on the side away from the first guide roller 4, around the second guide roller 5 on the side away from the tension roller 3, and finally pulled out for winding. The first guide roller 4 and the second guide roller 5 are positioned on both sides of the tension roller 3, pressing the material strip 40 of the material roll 41 against the surface of the tension roller 3. During the output process of the material strip 40, the torque of the tension roller 3 is controlled by a magnetic powder brake, thereby adjusting the output tension of the material strip 40. The tension roller 3 has a large contact area with the surface of the material strip 40. By controlling the torque of the tension roller 3 through the magnetic powder brake, and through the frictional force of the tension roller 3 on the surface of the material strip 40, the tension roller 3 is pulled, thereby controlling the tension of the material strip 40, accurately adjusting the output tension, and improving the winding quality of the composite material.

[0086] Specifically, it also includes: a support base 7, slidably connected to the support frame 1; a third guide roller 8, rotatably connected to the support base 7, located on the side of the second guide roller 5 away from the tension roller 3; a fourth guide roller 9, rotatably connected to the support frame 1, used to press the material strip 40 of the material roll 41 onto the surface of the third guide roller 8; and a pressure sensor 10, connected on one side to the support base 7 and on the other side to the support frame 1, used to detect the pressure of the material strip 40 on the surface of the third guide roller 8, and electrically connected to the first magnetic powder brake 6, thereby adjusting the output torque of the first magnetic powder brake 6 by the pressure of the material strip 40 on the surface of the third guide roller 8.

[0087] After the material strip 40 is output from the second guide roller 5, it passes around the third guide roller 8 away from the second guide roller 5, then passes around the fourth guide roller 9 away from the second guide roller 5, and then the material strip 40 is pulled out for winding. The second guide roller 5 and the fourth guide roller 9 are set on both sides of the tension roller 3, pressing the material strip 40 of the material roll 41 onto the surface of the third guide roller 8. When the tension of the material strip 40 increases or decreases, the tension of the material strip 40 is transmitted to the surface of the third guide roller 8, generating pressure on the third guide rail. The third guide roller 8 drives the support seat 7 to slide relative to the support frame 1. The support frame 1 transmits the tension of the material strip 40 to the pressure sensor 10. The pressure sensor 10 controls the first magnetic powder brake 6 to adjust the torque of the pressure roller rotation based on the change in the tension of the material strip 40, thereby controlling the tension of the material strip 40 in real time according to the change in the tension of the material strip 40, so that the tension of the material strip 40 is kept in a stable state.

[0088] Specifically, it also includes: a second magnetic powder controller 11, whose output shaft is coaxially and fixedly connected to the feeding roller 2, used to adjust the feeding torque of the feeding roller 2. The second magnetic powder controller 11 controls the tension of the material belt 40 by controlling the torque of the feeding roller 2, and works in conjunction with the first magnetic powder brake 6 to control the overall tension of the winding of the material belt 40.

[0089] Specifically, it also includes: a lower heating plate 12, fixedly installed on the support frame 1; and an upper heating plate 13, movably connected to the support frame 1, used to cooperate with the lower heating plate 12 to heat the joint of the material strip 40, thereby heating and connecting the joints of the two material strips 40. When the material strip 40 on the material roll 41 is used up, a new material roll 41 is replaced, and the joint of the two material strips 40 is placed between the lower heating plate 12 and the upper heating plate 13. The upper heating plate 13 and the lower heating plate 12 are used to clamp and heat the material strip 40, thermally bonding the two material strips 40 together, thus improving work efficiency.

[0090] Specifically, it also includes: a discharge frame 14, slidably connected to the support frame 1; a discharge roller 15, rotatably connected to the discharge frame 14, used to support the material strip 40, pressing the material strip 40 against the core mold surface, squeezing out excess air bubbles between layers, and improving the interlayer bonding quality of the material strip 40; and a drive component 16, drivenly connected to the discharge frame 14, used to drive the discharge frame 14 to slide, thereby moving the discharge roller 15 and changing the discharge position of the material strip 40. The drive component 16 drives the discharge frame 14 to move, the discharge frame 14 slides and drives the discharge roller 15 to move, and the discharge roller 15 pushes the material strip 40 to move, thereby changing the discharge position.

[0091] Specifically, it also includes: a first rotating ring 17, whose inner hole is rotatably sleeved with the first guide roller 4, and whose outer ring is rotatably connected to the support frame 1.

[0092] After prolonged use, the friction between the first guide roller 4, the second guide roller 5, and the fourth guide roller 9 and the support frame 1 gradually increases. Therefore, the rotational speed of the first guide roller 4 is different from that of the second guide roller 5 and the fourth guide roller 9, which causes friction on the material belt 40. At this time, the driving device drives the second magnetic block 20 to move. The second magnetic block 20 moves into the inner hole of the first rotating ring 17. The first magnetic block 18 moves under the attraction of the second magnetic block 20. The first elastic element 19 deforms, and the first magnetic block 18 separates from the support frame 1.

The fifth magnetic block 26 moves under the attraction of the sixth magnetic block 28. The third elastic element 27 deforms and the fifth magnetic block 26 separates from the support frame 1. The third rotating ring 25 can rotate relative to the support frame 1, thereby reducing the friction between the fourth guide roller 9 and the support frame 1. Finally, the rotation speed of the first guide roller 4 is the same as the rotation speed of the second guide roller 5 and the fourth guide roller 9, avoiding wear on the material belt 40 due to different rotation speeds.

[0093] Specifically, the driving device includes: a push block 29, which is fixedly connected to the second magnetic block 20, the fourth magnetic block 24, and the sixth magnetic block 28, respectively. A fourth elastic member 30, one end of which is connected to the push block 29 and the other end of which is connected to the support frame 1, is used to apply force to the support frame 1 to move the push block 29 closer to the first rotating ring 17, the second rotating ring 21, and the third rotating ring 25. A limiting block 31 is fixedly connected to the push block 29. A stop block 32 abuts against the push block 29 and is slidably connected to the support frame 1, with the sliding direction being different from the sliding direction between the push block 29 and the support frame 1. A driving assembly is drivenly connected to the stop block 32 to drive the stop block 32 to slide. When the limiting block 31 abuts against the stop block 32, the second magnetic block 20 moves away from the first magnetic block 18, the fourth magnetic block 24 moves away from the third magnetic block 22, the sixth magnetic block 28 moves away from the fifth magnetic block 26, the fourth elastic element 30 is in a deformed state, the driving component drives the stop block 32 to slide, the stop block 32 separates from the push block 29, the fourth elastic element 30 applies force to the push block 29, the fourth elastic element 30 drives the push block 29 to move, the push block 29 drives the second magnetic block 20 to move, the fourth magnetic block 24 to move and the sixth magnetic block 28 to move.

[0094] Specifically, the drive assembly includes: a first pulley 33, coaxially and fixedly connected to the fourth guide roller 9; a second pulley 34, coaxially and fixedly connected to the second guide roller 5; a third pulley 35, coaxially and fixedly connected to the first guide roller 4; a fourth pulley 36, rotatably connected to the support frame 1, located on the side of the third pulley 35 away from the second pulley 34; and a fifth pulley 37, rotatably connected to the stop block 32, located on the side of the first pulley 33 away from the second pulley 34. A transmission belt 38 has one end sleeved with the fourth pulley 36 and the other end sleeved with the fifth pulley 37. The first pulley 33, the second pulley 34, and the third pulley 35 are located between the two ends of the transmission belt 38, sequentially contacting one side of the belt body and separating from the other side of the belt body. A fifth elastic element 39 has one end connected to the stop block 32 and the other end connected to the support frame 1, used to apply force to the stop block 32, causing the fifth pulley 37 to move away from the fourth pulley 36.

[0095] During the material discharge process of belt 40, belt 40 drives the first pulley 33, the second pulley 34, and the third pulley 35 to rotate. When the speed of the first pulley 33 is less than the speed of the second pulley 34, the length of the transmission belt 38 between the first pulley 33 and the second pulley 34 increases. The transmission belt 38 pulls the fifth pulley 37, causing the fifth elastic element 39 to deform. The fifth pulley 37 drives the stop block 32 to move, so that the speed of the first pulley 33 is equal to the speed of the second pulley 34, thus avoiding damage to belt 40 due to the difference in speed. Wear is prevented when the speed of the first pulley 33 is greater than that of the second pulley 34. The first pulley 33 pulls the second rotating pulley through the transmission belt 38, so that the speed of the first pulley 33 is the same as that of the second pulley 34. This avoids wear on the material belt 40 due to different speeds. Similarly, the speed of the second pulley 34 can be kept the same as that of the third pulley 35, and the speed of the first pulley 33 can be kept the same as that of the third pulley 35. Ultimately, the speeds of the first pulley 33, the second pulley 34, and the third pulley 35 are all the same.

[0096] Specifically, the transmission belt 38 is a synchronous belt, the first pulley 33 is a synchronous pulley, the second pulley 34 is a synchronous pulley, the third pulley 35 is a synchronous pulley, the fourth pulley 36 is a synchronous pulley, and the fifth pulley 37 is a synchronous pulley. There will be no slippage between the synchronous belt and the synchronous pulleys, further ensuring that the rotational speeds of the first pulley 33, the second pulley 34, and the third pulley 35 are the same.

[0097] Specifically, the lower heating plate 12 and the upper heating plate 13 are hinged to each other.

[0098] Working principle and process

[0099] Please combine Figures 1-9The principle and process of the present invention are described in detail below: The material roll 41 is coaxially fixed to the feeding roller 2, so that the material strip 40 of the material roll 41 is pulled out and successively passes around the first guide roller 4 away from the tension roller 3, passes around the tension roller 3 away from the first guide roller 4, passes around the second guide roller 5 away from the tension roller 3, and finally pulls out the material strip 40 for winding. The first guide roller 4 and the second guide roller 5 are set on both sides of the tension roller 3, pressing the material strip 40 of the material roll 41 onto the surface of the tension roller 3. During the output process of the material strip 40, the torque of the rotation of the tension roller 3 is controlled by the magnetic powder brake, thereby adjusting the tension of the output of the material strip 40. After the material strip 40 is output from the second guide roller 5, it passes around the third guide roller 8 away from the second guide roller 5, then passes around the fourth guide roller 9 away from the second guide roller 5, and then the material strip 40 is pulled out for winding. The second guide roller 5 and the fourth guide roller 9 are set on both sides of the tension roller 3, pressing the material strip 40 of the material roll 41 onto the surface of the third guide roller 8. When the tension of the material strip 40 increases or decreases, the tension of the material strip 40 is transmitted to the surface of the third guide roller 8, generating pressure on the third guide rail. The third guide roller 8 drives the support seat 7 to slide relative to the support frame 1. The support frame 1 transmits the tension of the material strip 40 to the pressure sensor 10. The pressure sensor 10 controls the first magnetic powder brake 6 to adjust the torque of the pressure roller rotation based on the change in the tension of the material strip 40, thereby controlling the tension of the material strip 40 in real time according to the change in the tension of the material strip 40, so that the tension of the material strip 40 is kept in a stable state. The second magnetic powder controller 11 controls the tension of the material belt 40 by controlling the torque of the feeding roller 2, and works in conjunction with the first magnetic powder brake 6 to control the overall tension of the material belt 40 winding.
