Description

Technical Field

[0001] This invention relates to the field of rubber strip production technology, and more specifically to a rubber production winding device and method that facilitates adjustment of winding slack. Background Technology

[0002] Rubber strips are a common type of rubber product. During production, rubber strips are generally made into long strips, which are then rolled up by a winding roller. When in use, they are cut to the appropriate length according to actual needs.

[0003] According to publication (announcement) number CN110790054B, published (announcement) date 2021.01.05, a rapid winding device for producing rubber strips is disclosed, including a workbench, a cleaning device, a winding device, and a motor. The cleaning device is fixedly installed at the front end of the workbench, and the winding device is installed at the rear end of the workbench. The motor is installed at the left end of the winding device through a motor mount. The cleaning device includes a fixed frame, a cleaning inner wheel, and a cleaning outer wheel. Fixed frames are symmetrically installed on the left and right sides of the front end of the workbench. The cleaning inner wheel is installed on the upper end of the fixed frame through a pin, and the cleaning outer wheel is fixedly installed on the upper end of the fixed frame. The axis of the cleaning outer wheel coincides with that of the cleaning inner wheel. The rubber strip passes through the cleaning inner wheel and exits from the cleaning outer wheel. The gap between the cleaning inner wheel and the cleaning outer wheel is used to clean the rubber strip. The device uses the gap between the inner cleaning roller and the outer cleaning roller to clean the rubber strip, ensuring that the surface of the rubber strip is thoroughly cleaned. After cleaning, the rubber strip comes into contact with the winding roller, and the first and second clamping frames press the rubber strip during winding to prevent it from loosening and falling off during the winding process.

[0004] In the prior art, including the aforementioned patent, when performing the rubber strip winding operation, one end of the rubber strip is usually fixed directly to the winding roller, and the winding roller is driven to rotate. The winding roller winds up the rubber strip. However, during the winding process, the tensile force on the rubber strip is constantly changing, and the tension of the rubber strip wound on the winding roller is also different, resulting in a different amount of rubber strip that a single winding roller can wind up. Summary of the Invention

[0005] The purpose of this invention is to provide a rubber production winding device and method that facilitates the adjustment of winding slack, aiming to solve the problem that the different tension of the rubber strip wound by the winding roller leads to different amounts of rubber strip wound.

[0006] To achieve the above objectives, the present invention provides a rubber production winding device that facilitates adjustment of winding slack, comprising a frame on which:

[0007] A take-up roller has a fixing groove for fixing the end of the rubber strip;

[0008] The tensioning assembly includes clamping rollers symmetrically and movably mounted on the frame and cooperating to clamp the rubber strip, wherein:

[0009] The two clamping rollers move to stretch the rubber strip, and the two clamping rollers rotate synchronously with the take-up roller to keep the tension of the rubber strip constant when the take-up roller takes it up.

[0010] Preferably, the tensioning assembly includes a movable block movably mounted on the frame, on which a squeeze roller is movably disposed, and the movable block reciprocates in a direction parallel to the axis of the take-up roller.

[0011] Preferably, the tensioning assembly includes a mounting plate movably mounted on the frame, a reciprocating lead screw rotatably mounted on the mounting plate, and a through hole adapted to the reciprocating lead screw on the movable block.

[0012] Preferably, a drive assembly for driving the tensioning assembly to move relative to the take-up roller is movably disposed on the frame.

[0013] Preferably, the drive assembly includes a movable rod movably mounted on the frame and in close contact with the take-up roller, the movable rod being pushed and moved by the rubber strip to drive the tensioning assembly to move.

[0014] Preferably, the movable rod is provided with a first rack, the tensioning assembly is provided with a second rack, and the frame is provided with a second gear that meshes with the first rack and the second rack respectively.

[0015] Preferably, a first telescopic rod is provided between the tensioning assembly and the second rack.

[0016] Preferably, the take-up roller is provided with a first sprocket, the reciprocating screw is provided with a second sprocket, and a first chain is provided between the first sprocket and the second sprocket.

[0017] Preferably, a tensioning wheel is movably disposed on the frame to keep the first chain taut.

[0018] A rubber production winding method that facilitates adjustment of winding slack includes the rubber production winding device for facilitating adjustment of winding slack as described above, and further includes the following steps:

[0019] S1. Pass the end of the rubber strip through the clamping roller and insert it into the take-up roller;

[0020] S2. Adjust the distance between the tensioning assembly and the take-up roller according to the specified tension for the rubber strip winding;

[0021] S3. The take-up roller rotates to take up the rubber strip and drives the clamping roller to reciprocate in a direction parallel to the axis of the take-up roller;

[0022] S4. The rubber strip pushes the movable rod away from the take-up roller, and drives the tensioning assembly to move away from the take-up roller.

[0023] S5. After the rubber strip is wound up, cut the rubber strip and tie the rubber strip on the winding roller.

[0024] In the above technical solution, the present invention provides a rubber production winding device and method that facilitates adjustment of winding slack, which has the following beneficial effects: When winding rubber strips, the end of the rubber strip is passed between two clamping rollers and inserted into a fixed groove on the winding roller. The winding roller fixes the end of the rubber strip, and the clamping roller clamps the rubber strip. Then, the distance between the clamping roller and the winding roller is adjusted according to the tension specified when winding the rubber strip. The clamping roller stretches the rubber strip to keep the rubber strip at a constant tension. Then, the winding roller and the clamping roller are driven to rotate synchronously. The length of the rubber strip released by the clamping roller is the same as the length of the rubber strip wound by the winding roller, so that the tension of the rubber strip wound by the winding roller remains constant.

Detailed Implementation

[0037] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0038] like Figure 1-9 As shown, a rubber production winding device and method for easy adjustment of winding slack includes a frame 1, on which:

[0039] The take-up roller 11 has a fixing groove 116 for fixing the end of the rubber strip;

[0040] Tensioning assembly 12 includes clamping rollers 124 symmetrically and movably mounted on frame 1 and used to clamp the rubber strip, wherein:

[0041] The two clamping rollers 124 move to stretch the rubber strip, and the two clamping rollers 124 rotate synchronously with the take-up roller 11 to keep the tension of the rubber strip constant.

[0042] Specifically, when winding up the rubber strip, the end of the rubber strip is first fixed on the winding roller 11, and then the winding roller 11 is driven to rotate, and the winding roller 11 winds up the rubber strip. This is existing technology and will not be described in detail.

[0043] Furthermore, a fixed side plate 111 and a movable side plate 112 are respectively provided on both sides of the take-up roller 11. A fixed block 117 extending into the fixed groove 116 is symmetrically provided on the movable side plate 112. An insertion block 113 extending into the take-up roller 11 is provided on the movable side plate 112. Multiple locking rods 114 are movably provided on the insertion block 113 to lock it onto the take-up roller 11. A drive disc 115 for driving the multiple locking rods 114 to move is rotatably provided on the insertion block 113. The drive disc 115 is provided with a planar thread, and the locking rods 114 have openings that are flush with the planar surface. The threaded groove, the insertion block 113 is specifically a triangular prism and has a ramp on the side wall away from the movable side plate 112, the frame 1 is equipped with a motor for driving the take-up roller 11 to rotate; when taking up the rubber strip, the end of the rubber strip is passed between the two clamping rollers 124 and inserted into the fixing groove 116 on the take-up roller 11, then the movable side plate 112 is installed on the take-up roller 11, the fixing block 117 on the movable side plate 112 is inserted into the fixing groove 116, and the ramp on the front side of the fixing block 117 is inserted into the gap between the end of the rubber strip and the fixing groove 116 (to... Figure 9 According to the plan, the left side of the fixing block 117 is the front side. The triangular prism-shaped fixing block 117 is inserted into the fixing groove 116, so that the middle part of the end of the rubber strip is recessed, and the end of the rubber strip is fixed on the take-up roller 11. The clamping roller 124 clamps the rubber strip. Then, the distance between the clamping roller 124 and the take-up roller is adjusted according to the tension specified when the rubber strip is wound. The clamping roller 124 stretches the rubber strip to keep the rubber strip at a constant tension. The motor drives the take-up roller 11 and the clamping roller 124 to rotate synchronously. The length of the rubber strip released by the clamping roller 124 is the same as the length of the rubber strip wound by the take-up roller 11, so that the tension of the rubber strip wound by the take-up roller 11 remains constant.

[0044] Furthermore, in the above embodiments, an electric telescopic rod can be installed on the frame 1, and the tensioning component 12 can be movably installed on the output end of the electric telescopic rod. When it is necessary to adjust the tension of the rubber strip between the clamping roller 124 and the take-up roller 11, the electric telescopic rod is driven to extend, changing the distance between the clamping roller 124 and the take-up roller 11, thereby changing the tension of the rubber strip between the clamping roller 124 and the take-up roller 11. Alternatively, a rack and a gear meshing with and driven by the rack can be installed on the frame 1. When it is necessary to adjust the tension of the rubber strip between the clamping roller 124 and the take-up roller 11, the gear rotates, causing the rack to move, which in turn causes the tensioning component 12 to move, changing the distance between the clamping roller 124 and the take-up roller 11, thereby changing the tension of the rubber strip between the clamping roller 124 and the take-up roller 11. Other structures that can be obtained by those skilled in the art based on common technical knowledge are also acceptable.

[0045] In the above technical solution, when winding the rubber strip, the end of the rubber strip is passed between the two clamping rollers 124 and inserted into the fixing groove 116 on the winding roller 11. The winding roller 11 fixes the end of the rubber strip, and the clamping rollers 124 clamp the rubber strip. Then, the distance between the clamping rollers 124 and the winding roller is adjusted according to the tension specified when winding the rubber strip. The clamping rollers 124 stretch the rubber strip to keep the rubber strip at a constant tension. Then, the winding roller 11 and the clamping rollers 124 are driven to rotate synchronously. The length of the rubber strip released by the clamping rollers 124 is the same as the length of the rubber strip wound by the winding roller 11, so that the tension of the rubber strip wound by the winding roller 11 remains constant.

[0046] When winding the rubber strip, the take-up roller 11 still has the problem that the rubber strip cannot be evenly wound on the take-up roller 11, which affects the capacity of the take-up roller 11. As a further embodiment of the present invention, the tensioning assembly 12 includes a movable block 123 movably mounted on the frame 1, and a squeezing roller is movably disposed on the movable block 123. The movable block 123 reciprocates in a direction parallel to the axis of the take-up roller 11.

[0047] Specifically, when the take-up roller 11 rotates to take up the rubber strip, the movable block 123 moves back and forth along the direction parallel to the axis of the take-up roller 11, so that when the take-up roller 11 takes up the rubber strip, the landing point of the rubber strip on the take-up roller 11 changes continuously, so that the rubber strip is evenly taken up on the take-up roller 11.

[0048] As a further embodiment of the present invention, the tensioning assembly 12 includes a mounting plate 121 movably mounted on the frame 1, a reciprocating screw 122 rotatably mounted on the mounting plate 121, and a through hole adapted to the reciprocating screw 122 on the movable block 123.

[0049] Specifically, the axis of the reciprocating screw 122 is parallel to the axis of the take-up roller 11, and a guide rod 128 is provided between the movable block 123 and the mounting plate 121. The guide rod 128 can prevent the movable block 123 from rotating relative to the mounting plate 121.

[0050] Furthermore, as the take-up roller 11 rotates to take up the rubber strip, the reciprocating screw 122 rotates, driving the movable block 123 and the extrusion roller to move back and forth in a direction parallel to the axis of the take-up roller 11. This causes the landing point of the rubber strip on the take-up roller 11 to change continuously when the take-up roller 11 takes up the rubber strip, so that the rubber strip is evenly taken up on the take-up roller 11.

[0051] As the take-up roller 11 winds up the rubber strip, the diameter of the take-up roller 11 continuously increases, and the distance between the surface of the take-up roller 11 and the clamping roller 124 becomes closer and closer. This results in a decrease in the tension of the rubber strip between the take-up roller 11 and the clamping roller 124. As a further embodiment of the present invention, a drive assembly 13 for driving the tensioning assembly 12 to move relative to the take-up roller 11 is movably disposed on the frame 1.

[0052] Specifically, while the take-up roller 11 is taking up the rubber strip, the drive assembly 13 drives the tensioning assembly 12 to move away from the take-up roller 11, so that the distance between the surface of the take-up roller 11 and the clamping roller 124 remains approximately constant, thereby ensuring that the tension of the rubber strip between the take-up roller 11 and the clamping roller 124 remains approximately the same.

[0053] As another embodiment of the present invention, the drive assembly 13 includes a movable rod 131 that is movably mounted on the frame 1 and closely attached to the take-up roller 11. The movable rod 131 is pushed and moved by the rubber strip to drive the tensioning assembly 12 to move.

[0054] Specifically, ramps are provided on the side walls of the movable rod 131 on both sides.

[0055] Furthermore, while the take-up roller 11 is taking up the rubber strip, the rubber strip on the take-up roller 11 will push the movable rod 131 to move away from the take-up roller 11, thereby driving the tensioning assembly 12 to move away from the take-up roller 11, so that the distance between the surface of the take-up roller 11 and the clamping roller 124 remains approximately constant, thereby ensuring that the tension of the rubber strip between the take-up roller 11 and the clamping roller 124 remains approximately the same.

[0056] As another embodiment of the present invention, a first rack 132 is provided on the movable rod 131, a second rack 133 is provided on the tensioning assembly 12, and a second gear 134 is provided on the frame 1 to mesh with the first rack 132 and the second rack 133 respectively.

[0057] Specifically, while the take-up roller 11 is taking up the rubber strip, the rubber strip on the take-up roller 11 pushes the movable rod 131 to move away from the take-up roller 11. Then, the movable rod 131 drives the first rack 132 to move upward. The first rack 132 drives the second rack 133 to move through the second gear 134 that meshes with it. The second rack 133 drives the tensioning assembly 12 to move away from the take-up roller 11, so that the distance between the surface of the take-up roller 11 and the clamping roller 124 remains approximately constant, thereby ensuring that the tension of the rubber strip between the take-up roller 11 and the clamping roller 124 remains approximately the same.

[0058] As another embodiment of the present invention, a first telescopic rod 135 is provided between the tensioning assembly 12 and the second rack 133.

[0059] Specifically, the first telescopic rod 135 is a threaded telescopic rod.

[0060] Furthermore, before the take-up roller 11 takes up the rubber strip, the first telescopic rod 135 can be rotated to extend it. The first telescopic rod 135 drives the tensioning assembly 12 to move away from the take-up roller 11. The clamping roller 124 on the tensioning assembly 12 pulls the rubber strip so that the tension of the rubber strip is within the specified range. At this time, the take-up roller 11 can perform the take-up operation.

[0061] As another embodiment of the present invention, a first sprocket 136 is provided on the take-up roller 11, a second sprocket 137 is provided on the reciprocating screw 122, and a first chain 139 is provided between the first sprocket 136 and the second sprocket 137.

[0062] Specifically, when the take-up roller 11 is driven by the motor to rotate and take up the rubber strip, the first sprocket 136 on the take-up roller 11 rotates synchronously. The first sprocket 136 drives the second sprocket 137 to rotate through the first chain 139. The second sprocket 137 drives the reciprocating screw 122 to rotate. The movable block 123 on the reciprocating screw 122 moves back and forth in a direction parallel to the axis of the take-up roller 11 so that the rubber strip is evenly wound on the take-up roller 11.

[0063] As another embodiment of the present invention, a tensioning wheel 138 is movably provided on the frame 1 to keep the first chain 139 taut.

[0064] Specifically, a tenon block is slidably mounted on the frame 1, a spring is installed between the tenon block and the frame 1, and a tensioning wheel 138 is rotatably mounted on the tenon block.

[0065] Furthermore, as the tensioning assembly 12 moves away from the take-up roller 11, the second sprocket 137 also moves away from the first sprocket 136. At this time, the second sprocket 137 pulls the first chain 139, and the first chain 139 pulls the tensioning wheel 138 upward. The spring is stretched, keeping the first chain 139 taut so that the first chain 139 can transmit power.

[0066] As a further embodiment of the present invention, a limiting plate 14 for pushing against the movable side plate 112 is rotatably provided on the frame 1. A pin 141 for fixing it to the frame 1 is movably provided on the limiting plate 14. A first gear 125 is provided on each of the two clamping rollers 124, and the two first gears 125 mesh with each other. A square shaft 126 is movably provided on the mounting plate 121. A cylindrical block 127 is provided at both ends of the shaft 126. The cylindrical block 127 at the first end of the shaft 126 is rotatably mounted on the mounting plate 121. A third sprocket 147 is provided on one of the cylindrical blocks 127 of the shaft 126. A reciprocating screw 122 A fourth sprocket 148 is provided on the upper part, and a second chain 149 is provided between the third sprocket 147 and the fourth sprocket 148. A reciprocating screw 122 is provided, and a second telescopic rod 142 is provided on the limiting plate 14. A mounting box 143 is provided on the second telescopic rod 142, and a movable plate 144 is provided on the mounting box 143. A spring is provided between the movable plate 144 and the mounting box 143. A plurality of cylindrical blocks 127 on the movable plate 126 and support sleeves 145 on the end of the reciprocating screw 122 are respectively used to limit the second end of the shaft 126 and the end of the reciprocating screw 122. A third telescopic rod 1311 extending into the interior of the limiting plate 14 is provided on the movable rod 131.

[0067] Specifically, the take-up roller 11, the fixed side plate 111, and the movable side plate 112 are all provided with grooves arranged in a circumferential array. The grooves on the take-up roller 11, the fixed side plate 111, and the movable side plate 112 are combined to form multiple placement slots 118 for placing ropes. Multiple rollers 146 for forming the fixed side plate 111 and the movable side plate 112 are movably arranged on the frame 1, which can reduce the energy required to rotate the take-up roller 11.

[0068] Furthermore, when winding up the rubber strip, the end of the rubber strip is passed between the two clamping rollers 124 and inserted into the fixing groove 116 on the winding roller 11. Then, the movable side plate 112 is installed on the winding roller 11, and the fixing block 117 on the movable side plate 112 is inserted into the fixing groove 116. The slope on the front side of the fixing block 117 is inserted into the gap between the end of the rubber strip and the fixing groove 116. The triangular prism-shaped fixing block 117 is inserted into the fixing groove 116, so that the middle part of the end of the rubber strip is recessed, and the end of the rubber strip is fixed on the winding roller 11. The clamping roller 124 clamps the rubber strip. The drive disk 115 is rotated, and the flat thread on the drive disk 115 pushes the locking rod 114 to extend out from the insertion block 113 and insert into the winding roller 11, fixing the movable side plate 112 on the winding roller 11. Then, the rope for binding the rubber strip is fixed into the placement groove 118, and the clamping roller 124 clamps the rubber strip.

[0069] Push the limiting plate 14 to make it stand up, insert the pin 141 to fix the limiting plate 14 to the frame 1, pull the second telescopic rod 142 so that the support sleeve 145 on the movable plate 144 is aligned with the end of the reciprocating screw 122 and the cylindrical block 127 on the shaft 126. The movable plate 144 moves under the action of the spring, and the end of the reciprocating screw 122 and the cylindrical block 127 on the shaft 126 are respectively inserted into the corresponding support sleeve 145 to support the reciprocating screw 122 and the shaft 126. Pull the third telescopic rod 1311 on the movable rod 131 so that the third telescopic rod 1311 is inserted into the limiting plate 14. The third telescopic rod 1311 cooperates with the first rack 132 to restrict the movable rod 131 to move only up and down, and reduce the deformation of the movable rod 131 when it is pushed.

[0070] Then rotate the first telescopic rod 135 to increase the distance between the clamping roller 124 and the take-up roller 11. The clamping roller 124 stretches the rubber strip so that the tension of the rubber strip is within the predetermined take-up tension range. The second telescopic rod 142 also extends synchronously with the first telescopic rod 135. When the tensioning assembly 12 moves away from the take-up roller 11, the second sprocket 137 also moves away from the first sprocket 136. At this time, the second sprocket 137 will pull the first chain 139. The first chain 139 pulls the tensioning wheel 138 to move upward. The spring is stretched so that the first chain 139 is kept taut so that the first chain 139 can transmit power.

[0071] The motor drives the take-up roller 11 to rotate, and the take-up roller 11 winds up the rubber strip. The first sprocket 136 on the take-up roller 11 rotates synchronously. The first sprocket 136 drives the second sprocket 137 to rotate through the first chain 139. The second sprocket 137 drives the reciprocating screw 122 to rotate. The movable block 123 on the reciprocating screw 122 moves back and forth in a direction parallel to the axis of the take-up roller 11. The extrusion roller also slides on the square shaft 126 to make the rubber strip evenly wound onto the take-up roller 11. The multi-lead screw 122 drives the fourth sprocket 148 to rotate synchronously. The fourth sprocket 148 drives the third sprocket 147 to rotate via the second chain 149. The third sprocket 147 drives the square shaft 126 to rotate via the cylindrical block 127. The square shaft 126 drives the extrusion roller and the first gear 125 to rotate. The two first gears 125 rotate synchronously, driving the two extrusion rollers to rotate synchronously, releasing a fixed length of rubber strip to the take-up roller 11, so that the tension of the rubber strip wound by the take-up roller 11 remains constant.

[0072] When the take-up roller 11 takes up the rubber strip, the rubber strip on the take-up roller 11 pushes the movable rod 131 to move away from the take-up roller 11. Then the movable rod 131 drives the first rack 132 to move upward. The first rack 132 drives the second rack 133 to move through the second gear 134 that meshes with it. The second rack 133 drives the tensioning assembly 12 to move away from the take-up roller 11 so that the distance between the surface of the take-up roller 11 and the clamping roller 124 remains approximately constant, thereby ensuring that the tension of the rubber strip between the take-up roller 11 and the clamping roller 124 remains approximately the same.

[0073] After the rubber strip winding is completed, pull the rope out of the placement groove 118 and tie the rubber strip on the winding roller 11. Cut off the excess rubber strip, move the movable plate 144 to separate the support sleeve 145 on the movable plate 144 from the reciprocating screw 122 and the cylindrical block 127. At this time, the movable plate 144 can be separated from the tensioning assembly 12. Shorten the second telescopic rod 142, pull out the third telescopic rod 1311 on the movable rod 131 from the limiting plate 14, pull out the pin 141, rotate the limiting plate 14 so that the limiting plate 14 no longer blocks the movable side plate 112, rotate the drive disc 115 to drive the locking rod 114 back into the insertion block 113, remove the movable side plate 112 from the winding roller 11, separate the fixing block 117 from the end of the rubber strip and no longer fix the rubber strip. At this time, the tied rubber strip can be removed from the winding roller 11 for the next winding operation.

[0074] This invention also provides a rubber production winding method that facilitates adjustment of winding slack, comprising the following steps:

[0075] S1. Pass the end of the adhesive strip through the two clamping rollers 124 and insert it into the fixing groove 116 on the take-up roller 11. Then install the movable side plate 112 onto the take-up roller 11. Insert the fixing block 117 on the movable side plate 112 into the fixing groove 116. Insert the slope on the front side of the fixing block 117 into the gap between the end of the adhesive strip and the fixing groove 116. Insert the triangular prism-shaped fixing block 117 into the fixing groove 116 to make the middle part of the end of the adhesive strip concave. Fix the end of the adhesive strip onto the take-up roller 11. The clamping roller 124 clamps the adhesive strip. Rotate the drive disk 115. The flat thread on the drive disk 115 pushes the locking rod 114 to extend out from the insertion block 113 and insert into the take-up roller 11. Fix the movable side plate 112 onto the take-up roller 11. Then fix the rope for binding the adhesive strip into the placement groove 118. The clamping roller 124 clamps the adhesive strip.

[0076] S2. Push the limiting plate 14 to make it stand up, insert the pin 141 to fix the limiting plate 14 to the frame 1, pull the second telescopic rod 142 so that the support sleeve 145 on the movable plate 144 is aligned with the end of the reciprocating screw 122 and the cylindrical block 127 on the shaft 126. The movable plate 144 moves under the action of the spring, and the end of the reciprocating screw 122 and the cylindrical block 127 on the shaft 126 are respectively inserted into the corresponding support sleeve 145 to support the reciprocating screw 122 and the shaft 126. Pull the third telescopic rod 1311 on the movable rod 131 so that the third telescopic rod 1311 is inserted into the limiting plate 14. The third telescopic rod 1311 cooperates with the first rack 132 to restrict the movable rod 131 to move only up and down, and reduce the deformation of the movable rod 131 when it is pushed.

[0077] S3. Then rotate the first telescopic rod 135 to increase the distance between the clamping roller 124 and the take-up roller 11. The clamping roller 124 stretches the rubber strip so that the tension of the rubber strip is within the predetermined take-up tension range. The second telescopic rod 142 also extends synchronously with the first telescopic rod 135. When the tensioning assembly 12 moves away from the take-up roller 11, the second sprocket 137 also moves away from the first sprocket 136. At this time, the second sprocket 137 will pull the first chain 139. The first chain 139 pulls the tensioning wheel 138 to move upward. The spring is stretched so that the first chain 139 is kept taut so that the first chain 139 can transmit power.

[0078] S4. The motor drives the take-up roller 11 to rotate, and the take-up roller 11 winds up the rubber strip. The first sprocket 136 on the take-up roller 11 rotates synchronously. The first sprocket 136 drives the second sprocket 137 to rotate through the first chain 139. The second sprocket 137 drives the reciprocating screw 122 to rotate. The movable block 123 on the reciprocating screw 122 moves back and forth in a direction parallel to the axis of the take-up roller 11. The extrusion roller also slides on the square shaft 126 to make the rubber strip evenly wound on the take-up roller 11. The reciprocating screw 122 drives the fourth sprocket 148 to rotate synchronously. The fourth sprocket 148 drives the third sprocket 147 to rotate via the second chain 149. The third sprocket 147 drives the square shaft 126 to rotate via the cylindrical block 127. The square shaft 126 drives the extrusion roller and the first gear 125 to rotate. The two first gears 125 rotate synchronously, driving the two extrusion rollers to rotate synchronously, releasing a fixed length of rubber strip to the take-up roller 11, so that the tension of the rubber strip wound by the take-up roller 11 remains constant.

[0079] S5. The rubber strip on the take-up roller 11 pushes the movable rod 131 to move away from the take-up roller 11. Then the movable rod 131 drives the first rack 132 to move upward. The first rack 132 drives the second rack 133 to move through the second gear 134 meshing with it. The second rack 133 drives the tensioning assembly 12 to move away from the take-up roller 11 so that the distance between the surface of the take-up roller 11 and the clamping roller 124 remains approximately constant, thereby ensuring that the tension of the rubber strip between the take-up roller 11 and the clamping roller 124 remains approximately the same.

[0080] S6. After the rubber strip winding is completed, pull the rope out of the placement groove 118 and tie the rubber strip on the winding roller 11. Cut off the excess rubber strip, move the movable plate 144 to separate the support sleeve 145 on the movable plate 144 from the reciprocating screw 122 and the cylindrical block 127. At this time, the movable plate 144 can be separated from the tensioning assembly 12. Shorten the second telescopic rod 142, pull the third telescopic rod 1311 on the movable rod 131 out of the limiting plate 14, pull off the pin 141, rotate the limiting plate 14, and the limiting plate 14 will no longer block the movable side plate 112. Rotate the drive disk 115 to drive the locking rod 114 back into the insertion block 113, remove the movable side plate 112 from the winding roller 11, and separate the fixing block 117 from the end of the rubber strip. The rubber strip is no longer fixed. At this time, the tied rubber strip can be removed from the winding roller 11 for the next winding operation.

[0081] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
