Description

Technical Field

[0001] The present invention relates to the technical field of rubber sheet production, and specifically to a production conveying device for fireproof rubber sheets. Background Art

[0002] A fireproof rubber sheet (hereinafter referred to as rubber sheet) is a functional material prepared with rubber as the matrix by adding flame retardants and high-temperature resistant fillers. It has excellent flame retardancy, high-temperature resistance, and insulation performance, and is widely used in fields such as building fire isolation, interior decoration of rail transit, and protection of power equipment. Rubber sheets are usually made through processes such as mixing, calendering, vulcanization, and cooling. Finally, the completed rubber sheets are wound and packaged by a conveying device for convenient subsequent transportation and storage.

[0003] When conveying rubber sheets, they are usually conveyed to a winding roller by conveying rollers. After the rubber sheets are wound to a preset coil diameter, they are cut, rewound, and packaged manually or by a rewinding device. A tensioning roller is arranged between the conveying roller and the winding roller to tension the rubber sheets to ensure that the rubber sheets are closely attached layer by layer, which is beneficial for subsequent packaging and transportation.

[0004] However, the above rubber sheet conveying process has the following problems: 1. The rubber sheet deflects: The rubber sheet may deflect in the front-back direction during the conveying process, resulting in uneven edges of the wound coil, which in turn affects the subsequent packaging of the rubber sheet. In some cases, it may even be necessary to stop the machine and correct the deviation of the rubber sheet, leading to a reduction in the conveying efficiency of the rubber sheet.

[0005] 2. The rubber sheet is over-tensioned: Due to the certain thickness of the rubber sheet, the radius of the rubber sheet roll increases rapidly. As the winding radius of the rubber sheet increases, the tensioning force of the tensioning roller on the rubber sheet also increases, resulting in a risk that the rubber sheet may be over-stretched or even broken, thereby reducing the quality of the rubber sheet. Summary of the Invention

[0006] To solve the above technical problems, the present invention adopts the following technical solutions. A fireproof rubber sheet production and conveying device includes a conveying and winding machine, on which a tensioning unit is installed, and also includes a deviation rectifying unit, a flattening unit and a guiding unit; the tensioning unit includes a gantry fixedly installed in the middle of the upper end of the conveying and winding machine.

A tensioning roller is rotatably installed on both the front and rear sides of the connecting frame. The tensioning adjustment group is used to adjust the tension of the tensioning roller; the deviation rectifying unit is used to correct the front and rear positions of the rubber sheet. The deviation rectifying unit includes two deviation rectifying baffles arranged symmetrically before and after and distributed outside the tensioning roller.

The lower end of the inclined plate inclines to the left and is an elastic telescopic structure. The lower end of the inclined plate is hinged with a flattening plate for flattening the rubber sheet.

When the rubber sheet is skewed, the pressing group makes the deviation rectifying baffle push the rubber sheet, and at the same time the pulling group cooperates to pull the rubber sheet to complete the position deviation rectification of the rubber sheet; the pressing group, the deviation rectifying baffle and the pulling group form a dynamic deviation rectification mechanism; the guiding unit is arranged on the right side of the tensioning unit and is used to prevent the rubber sheet from being skewed again.

[0007] Preferably, the tensioning adjustment group includes a hydraulic rod fixedly installed in the middle of the inner top wall of the gantry. The lower end of the hydraulic rod is fixedly installed with a lower pressing plate. Between the upper end of the lower pressing plate and the gantry, there are a plurality of guiding rods connected. The lower end of the lower pressing plate is connected to the upper side of the connecting frame through a plurality of elastic tensioning rods arranged evenly in the front and back. The elastic tensioning rod is a telescopic structure.

[0008] Preferably, the pressing group includes a fixing plate fixedly sleeved outside the tensioning roller. On the opposite sides of the two fixing plates, there are pressing plates installed through a plurality of reset springs arranged evenly in the circumferential direction. And the pressing plate is movably sleeved outside the tensioning roller. On the opposite sides of the two pressing plates, there are a plurality of L-shaped matching rods arranged evenly in the circumferential direction fixedly installed.

[0009] Preferably, on the front and rear inner walls of the connecting frame, there are a plurality of matching blocks arranged evenly in the circumferential direction fixedly installed. The side of the matching block away from the connecting frame is set as an inclined surface matching with the matching rod.

[0010] Preferably, on the opposite sides of the two pressing plates, there are a plurality of elastic pressing rods arranged evenly in the circumferential direction fixedly installed. The fixed ends of the elastic pressing rods slide through the corresponding fixing plates in the front and back, and the telescopic ends of the elastic pressing rods are fixedly connected to their corresponding deviation rectifying baffles.

[0011] Preferably, the reciprocating group includes a reciprocating plate slidably mounted on the left side of the connecting frame in the front-back direction. The lower end of the reciprocating plate is fixedly connected to the inclined plate. The reciprocating plate is mounted on the threaded rod by means of threaded fit, and the threaded rod is rotatably connected to the connecting frame. The front end of the threaded rod penetrates through the connecting frame and is fixedly connected to the output shaft of the reciprocating motor fixedly installed outside the connecting frame.

[0012] Preferably, the pulling group includes a square sliding sleeve slidably sleeved on the end of the ironing plate in the front-back direction. A top extension spring is connected between the inner wall of the square sliding sleeve and the end face of the ironing plate. The lower end of the square sliding sleeve is fixedly installed with a lifting plate having an L-shaped structure.

[0013] Preferably, the pulling group further includes two elastic connecting columns symmetrically arranged in the front-back direction and fixedly installed at the lower end of the ironing plate. The elastic connecting columns are of telescopic structure. The lower ends of the elastic connecting columns are fixedly installed with pulling plates. Tightening wheels are rotatably connected to the opposite sides of the two pulling plates, and friction plates are provided at the rotational connection of the pulling plates and the tightening wheels.

[0014] Preferably, two limiting plates symmetrically arranged in the front-back direction are fixedly installed on the left side of the connecting frame, and the opposite sides of the two limiting plates are in contact with the corresponding square sliding sleeves.

[0015] Preferably, the guiding unit includes a connecting plate fixedly installed on the right side of the connecting frame. A yielding plate of elastic telescopic structure is fixedly installed on the lower side of the connecting plate. The lower end of the yielding plate is arranged obliquely to the right and is hinged to a square frame. Two groups of guiding wheel sets symmetrically arranged in the front-back direction are rotatably installed on the upper and lower inner walls of the square frame. The guiding wheel sets include a plurality of guiding wheels evenly arranged in the left-right direction.

[0016] The beneficial effects of the present invention are as follows: 1. When the rubber plate is deflected in the front-back direction, the present invention pushes the deflected side of the rubber plate by setting a deviation rectifying unit, and at the same time pulls the side of the rubber plate away from its deflected side through the pulling group, and applies a flattening force pointing away from its deflected side to the rubber plate through the moving ironing plate. The deviation rectification of the position of the rubber plate is completed by the cooperation of the pushing force, the pulling force and the flattening force, and a dynamic position deviation rectification mechanism is formed during the conveying and winding of the rubber plate, so as to prevent the rubber plate from being deflected in the front-back direction, thereby improving the winding quality and efficiency of the rubber plate.

[0017] 2. The present invention tightens the rubber plate downward by setting a tensioning unit. As the winding diameter of the wound rubber plate increases, the tensioning unit is controlled by the tensioning adjustment group to synchronously reduce the tension of the rubber plate, preventing the rubber plate from being overstretched or even broken, thereby ensuring the quality of the rubber plate.

[0018] 3. The present invention prevents the rubber plate from being deflected again by setting a guiding unit, thereby further ensuring that the edges of the wound coil are flush, improving the winding quality of the rubber plate, and ensuring the conveying efficiency of the rubber plate.

Specific Embodiments

[0029] The embodiments described below are exemplary and are only used to explain the present invention and should not be construed as limiting the present invention. For those embodiments where specific technologies or conditions are not indicated, they shall be carried out according to the technologies or conditions described in the literature in the field or according to the product specifications.

[0030] Refer to Figure 1 、 Figure 2 and Figure 8 , a production conveying device for a fireproof rubber sheet, comprising a conveying and winding machine 1, a tensioning unit 2 for tensioning the rubber sheet is installed on the conveying and winding machine 1, a deviation rectifying unit 3 for rectifying the front and rear ends of the rubber sheet is installed on the tensioning unit 2, a flattening unit 4 for flattening the rubber sheet is installed on the left side of the tensioning unit 2, and a guiding unit 5 for preventing the rubber sheet from being secondarily skewed is installed on the right side of the tensioning unit 2.

[0031] It should be noted that the conveying and winding machine 1 includes a base, a conveying roller assembly and a winding roller assembly. The conveying roller assembly is installed at the left end of the upper side of the base, and the winding roller assembly is installed at the right end of the upper side of the base. The conveying roller assembly is used to convey the rubber sheet to the right, and the winding roller assembly is used to wind the rubber sheet. Moreover, the winding roller of the winding roller assembly is installed on the winding roller assembly in a detachable manner, so that the rubber sheet wound to a preset coil diameter can be changed by manual or an external rewinder.

[0032] The present invention is used to convey the rubber sheet, and as the coil diameter of the wound rubber sheet increases, the present invention can synchronously reduce the tension force on the rubber sheet, thereby preventing the rubber sheet from being overstretched or even broken, ensuring the quality of the rubber sheet. At the same time, the present invention can also prevent the rubber sheet from being skewed in the front and rear directions, ensuring that the edges of the wound coil are flush, thereby improving the conveying efficiency of the rubber sheet.

[0033] Specifically, first, the end of the rubber sheet is sequentially wound around the conveying roller assembly, the tensioning unit 2 and the winding roller assembly of the conveying and winding machine 1, and the end of the rubber sheet is fixed to the winding roller of the winding roller assembly through an existing fixing structure. Then, the tensioning unit 2 is controlled to tension the rubber sheet downward and adjust the tension force applied to the rubber sheet. Next, the conveying roller assembly of the conveying and winding machine 1 is started to convey the rubber sheet to the right, and the winding roller assembly of the conveying and winding machine 1 is started to wind the rubber sheet. The flattening unit 4 and the deviation rectifying unit 3 cooperate to prevent the rubber sheet from being skewed in the front and rear directions, and the guiding unit 5 can prevent the rubber sheet from being secondarily skewed, making the edges of the coil wound by the winding roller assembly flush. And as the coil diameter of the wound rubber sheet increases, the tension force applied by the tensioning unit 2 to the rubber sheet synchronously decreases. When the rubber sheet is wound to the preset coil diameter, the winding roller of the winding roller assembly for winding the rubber sheet is removed by manual or an external rewinder, and a new winding roller is replaced, and the above operations are repeated, thereby continuously conveying and winding the rubber sheet.

[0034] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 8, the tensioning unit 2 includes a gantry 21 fixedly installed in the middle of the upper end of the base. The inner top wall of the gantry 21 is provided with a U-shaped connecting frame 23 through a tensioning adjustment group 22. A tensioning roller 24 is rotatably installed on both the front and rear sides of the connecting frame 23. The tensioning adjustment group 22 is used to adjust the tensioning force of the tensioning roller 24. A driving member 25 is connected between the front end of the tensioning roller 24 and the connecting frame 23.

[0035] It should be noted that the driving member 25 in the present invention includes a motor and a motor frame. The output shaft of the motor is fixedly connected to the tensioning roller 24, and the motor is fixedly connected to the connecting frame 23 through the motor frame. The tensioning roller 24 is driven to rotate by starting the motor.

[0036] The tensioning unit 2 is used to tension the rubber plate; specifically, first, the end of the rubber plate is sequentially wound around the conveying roller assembly of the conveying and winding machine 1, the lower side of the tensioning roller 24, and the winding roller assembly, and then the tensioning adjustment group 22 is controlled according to the performance of the rubber plate to drive the tensioning roller 24 to move downward through the connecting frame 23 so that the tensioning roller 24 tensions the rubber plate downward. When the rubber plate is conveyed and wound, the driving member 25 is controlled to drive the tensioning roller 24 to rotate synchronously. As the winding diameter of the wound rubber plate increases, the tensioning adjustment group 22 is controlled to synchronously reduce the tensioning force of the tensioning roller 24 on the rubber plate, thereby preventing the rubber plate from being overstretched or even broken and ensuring the quality of the rubber plate.

[0037] Refer to Figure 2 and Figure 4 , the tensioning adjustment group 22 includes a hydraulic rod 221 fixedly installed in the middle of the inner top wall of the gantry 21. A lower pressing plate 222 is fixedly installed at the lower end of the hydraulic rod 221. A plurality of guide rods 223 are connected between the upper end of the lower pressing plate 222 and the gantry 21. The lower end of the lower pressing plate 222 is connected to the upper side of the connecting frame 23 through a plurality of elastic tensioning rods 224 arranged evenly in the front and rear. The elastic tensioning rod 224 is a telescopic structure; wherein, both the front and rear sides of the connecting frame 23 are slidably connected to the gantry 21 through guide plates.

[0038] The tensioning adjustment group 22 is used to adjust the tensioning force of the tensioning roller 24 on the rubber plate; specifically, the hydraulic rod 221 is controlled to move the lower pressing plate 222 downward, and then finally drive the tensioning roller 24 to move downward. The tensioning roller 24 tensions the rubber plate downward. As the lower pressing plate 222 moves downward, the elastic tensioning rod 224 is compressed, and the compression amount of the elastic tensioning rod 224 is proportional to the elastic force generated by it (following Hooke's law F = kx) Therefore, by controlling the compression amount of the elastic tension rod 224, the tension force of the tension roller 24 on the rubber sheet can be adjusted. As the coil diameter of the wound rubber sheet increases, the hydraulic rod 221 is controlled to drive the lower pressing plate 222 to move upward synchronously, reducing the compression amount of the elastic tension rod 224, thereby reducing the tension force of the tension roller 24 on the rubber sheet, preventing the rubber sheet from being overstretched or even broken, and ensuring the quality of the rubber sheet. It should be noted that the hydraulic rod 221 can accurately respond to the change in the coil diameter through sensor feedback, and dynamically adjust the position of the lower pressing plate 222 to maintain an appropriate compression amount of the elastic tension rod 224.

[0039] Refer to Figure 2 , Figure 4 and Figure 8 , the deviation rectifying unit 3 includes two deviation rectifying baffles 31 arranged symmetrically before and after on the outer side of the tension roller 24, and extrusion groups 32 are connected between the back sides of the two deviation rectifying baffles 31 and the tension roller 24.

[0040] Refer to Figure 1 , Figure 3 and Figure 8 , the flattening unit 4 includes an inclined plate 42 installed on the left side of the connecting frame 23 through a reciprocating group 41. The lower end of the inclined plate 42 is arranged to incline to the left and is set as an elastic telescopic structure. The lower end of the inclined plate 42 is hinged with a flattening plate 43, and pulling groups 44 for pulling the ends of the rubber sheet are installed at both the front and rear ends of the flattening plate 43; among them, a first torsion spring is installed at the hinge joint between the inclined plate 42 and the flattening plate 43, and both the first torsion spring and the elastic telescopic structure of the inclined plate 42 have relatively small elastic forces, so that the flattening plate 43 does not press down on the rubber sheet.

[0041] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8 , the deviation rectifying unit 3 is used to cooperate with the flattening unit 4 to rectify the deviation of the rubber sheet; specifically, when the end of the rubber sheet bypasses the lower side of the tension roller 24, at this time the rubber sheet is located between the two deviation rectifying baffles 31, and the flattening plate 43 is always adaptively attached to the upper side of the rubber sheet under the action of its hinge with the inclined plate 42 and the elastic telescopic structure of the inclined plate 42 (at this time the rubber sheet between the conveying roller assembly and the tension roller 24 is in an inclined state). When the tension roller 24 rotates, the tension roller 24 drives the deviation rectifying baffles 31 to rotate synchronously through the extrusion groups 32, and at the same time the extrusion groups 32 drive the two deviation rectifying baffles 31 to reciprocate inward and outward synchronously (i.e., reciprocate back and forth). At the same time, the reciprocating group 41 is started to drive the flattening plate 43 to reciprocate back and forth through the inclined plate 42, so that the flattening plate 43 flattens the rubber sheet, ensuring the flatness of the rubber sheet surface, and the pulling groups 44 arranged along the moving direction of the flattening plate 43 can synchronously pull the ends of the rubber sheet, ensuring the complete flattening of the rubber sheet.

[0042] When there is no skew of the rubber sheet in the front-back direction, when the two deviation rectifying baffles 31 move towards each other to the limit position, both of the two deviation rectifying baffles 31 only slightly contact the front and rear ends of the rubber sheet, playing a role of continuously limiting the rubber sheet in the subsequent process; when there is a skew of the rubber sheet in the front-back direction, taking the rubber sheet skewing forward as an example to illustrate: when the rubber sheet skews forward, when the deviation rectifying baffle 31 in the front moves towards the middle of the tensioning roller 24, it can push the front end of the rubber sheet. At the same time, cooperating with the flattening operation of the flattening plate 43 and the pulling operation of the pulling group 44 located at the rear, the position deviation rectification of the rubber sheet is completed, and thus the continuous dynamic position deviation rectification of the rubber sheet can be realized.

[0043] Refer to Figure 4 , the extrusion group 32 includes fixing plates 321 fixedly sleeved on the outer side of the tensioning roller 24. On the opposite sides of the two fixing plates 321, extrusion plates 323 are installed through a plurality of circumferentially uniformly arranged return springs 322, and the extrusion plates 323 are movably sleeved on the outer side of the tensioning roller 24. On the opposite sides of the two extrusion plates 323, a plurality of circumferentially uniformly arranged L-shaped structure cooperating rods 324 are fixedly installed; on the front and rear inner walls of the connecting frame 23, a plurality of circumferentially uniformly arranged cooperating blocks 231 are fixedly installed. The side of the cooperating block 231 away from the connecting frame 23 is provided with an inclined surface that cooperates with the cooperating rod 324; on the opposite sides of the two extrusion plates 323, a plurality of circumferentially uniformly arranged elastic extrusion rods 325 are fixedly installed. The fixed ends of the elastic extrusion rods 325 slide through the corresponding fixing plates 321 in the front and rear directions, and the telescopic ends of the elastic extrusion rods 325 are fixedly connected to their corresponding deviation rectifying baffles 31.

[0044] It should be noted that the elastic extrusion rod 325 is provided with a relatively large elastic force. When the deviation rectifying baffle 31 abuts against the skewed end of the rubber sheet, at this time, under the elastic force of the corresponding plurality of elastic extrusion rods 325, the driving force exerted by the deviation rectifying baffle 31 on the end of the rubber sheet can overcome the tension acting on the rubber sheet, the frictional force existing between the rubber sheet and the tensioning roller 24, and the elastic force of the rubber sheet itself, ensuring that the deviation rectifying baffle 31 can push the skewed end of the rubber sheet.

[0045] The extrusion group 32 is used to drive two deviation-correcting baffles 31 to extrude the front and rear ends of the rubber plate; specifically, when the tensioning roller 24 rotates, the tensioning roller 24 finally drives the deviation-correcting baffle 31 and the extrusion plate 323 to rotate synchronously through the fixing plate 321 and the elastic extrusion rod 325. The extrusion plate 323 drives the matching rod 324 to rotate synchronously. When the matching rod 324 contacts the inclined surface of the matching block 231 and continues to rotate, the matching rod 324 drives the extrusion plate 323 to move towards the middle of the tensioning roller 24 under the action of the inclined surface of the matching block 231, compresses the return spring 322 and drives the elastic extrusion rod 325 to move synchronously. Moreover, multiple matching rods 324 can be matched with the inclined surfaces of the corresponding matching blocks 231 synchronously, increasing the stability when the extrusion plate 323 moves. The extrusion plate 323 drives the deviation-correcting baffle 31 to move towards the middle of the tensioning roller 24 through the elastic extrusion rod 325. Before the deviation-correcting baffle 31 contacts the rubber plate, the elastic extrusion rod 325 does not expand or contract; when the deviation-correcting baffle 31 corrects the position of the deflected rubber plate, taking the rubber plate deflecting forward as an example: when the rubber plate deflects forward, at this time, the deviation-correcting baffle 31 in the front contacts the front end of the rubber plate and pushes the front end of the rubber plate under the action of the corresponding multiple elastic extrusion rods 325. At the same time, cooperating with the flattening operation of the flattening plate 43 and the pulling operation of the pulling group 44 at the rear, the position correction of the rubber plate is completed. And when the matching rod 324 and the matching block 231 are separated, the extrusion plate 323 drives the two deviation-correcting baffles 31 to return to the initial position under the action of the return spring 322. And there are multiple matching blocks 231, so that the two deviation-correcting baffles 31 can continuously move in and out synchronously, forming a dynamic position correction mechanism, achieving the effect of preventing the rubber plate from deflecting in the front and rear directions.

[0046] Refer to Figure 3 , the reciprocating group 41 includes a reciprocating plate 411 slidably mounted front and rear on the left side of the connecting frame 23. The lower end of the reciprocating plate 411 is fixedly connected to the inclined plate 42. The reciprocating plate 411 is mounted on the threaded rod 412 by means of a threaded fit. And the threaded rod 412 is rotatably connected to the connecting frame 23. The front end of the threaded rod 412 penetrates through the connecting frame 23 and is fixedly connected to the output shaft of the reciprocating motor 413 fixedly mounted outside the connecting frame 23.

[0047] The reciprocating group 41 drives the flattening plate 43 to reciprocate back and forth through the inclined plate 42; specifically, start the reciprocating motor 413 to drive the threaded rod 412 to rotate forward and backward reciprocally, so that the threaded rod 412 drives the reciprocating plate 411 to reciprocate back and forth through the threaded fit, and then the reciprocating plate 411 drives the flattening plate 43 to reciprocate back and forth through the inclined plate 42.

[0048] Refer to Figure 3 、 Figure 5 、 Figure 6 and Figure 8, the pulling group 44 includes a square sliding sleeve 441 that slides back and forth on the end of the screed board 43. A jacking spring 442 is connected between the inner wall of the square sliding sleeve 441 and the end face of the screed board 43. A lifting plate 443 with an L-shaped structure is fixedly installed at the lower end of the square sliding sleeve 441, and inclined surfaces are provided on the opposite sides of the two lifting plates 443; two elastic connecting columns 444 arranged symmetrically before and after are fixedly installed at the lower end of the screed board 43. The elastic connecting column 444 is a telescopic structure, and a pulling plate 445 is fixedly installed at the lower end of the elastic connecting column 444. Tightening wheels 446 are rotatably connected to the opposite sides of the two pulling plates 445, and friction plates are provided at the rotational connection of the pulling plate 445 and the tightening wheel 446. The opposite sides of the two pulling plates 445 are both provided with outwardly convex arc-shaped structures. It should be noted that the friction plate has a relatively small frictional force.

[0049] When the tightening wheel 446 and the screed board 43 cooperate to clamp the end of the rubber plate and pull the rubber plate, under the action of the friction plate, a certain resistance acts on the rotational connection of the tightening wheel 446 and the pulling plate 445, so that the tightening wheel 446 can stably cooperate with the screed board 43 to apply a certain pulling force to the clamped end of the rubber plate; when the rubber plate does not deflect, the tightening wheel 446 does not cooperate with the screed board 43 to clamp the rubber plate, and the tightening wheel 446 only contacts the rubber plate. Then, during the forward and backward movement of the tightening wheel 446 along with the screed board 43 (during this process, the pulling plate 445 does not contact the inclined surface of the lifting plate 443), due to the rubber plate itself having a certain elasticity and there being a frictional force between the tightening wheel 446 and the rubber plate, at this time, the frictional force at the rotational connection of the tightening wheel 446 and the pulling plate 445 is overcome, and the tightening wheel 446 will rotate, thereby preventing the rubber plate that was not originally deflected from deflecting due to the movement of the tightening wheel 446.

[0050] Refer to Figure 3 , two limit plates 232 arranged symmetrically before and after are fixedly installed on the left side of the connecting frame 23, and the opposite sides of the two limit plates 232 are both in contact with the corresponding square sliding sleeve 441.

[0051] Refer to Figure 3 、 Figure 5 、 Figure 6 and Figure 8, the pulling group 44 is used to pull the end of the rubber plate; specifically, before the end of the rubber plate bypasses the lower side of the tensioning roller 24, the rubber plate passes through between the pulling plate 445 and the flattening plate 43. At this time, the pressing wheel 446 and the rubber plate do not come into contact. When the flattening plate 43 reciprocates back and forth, the square sliding sleeve 441 in the moving direction of the flattening plate 43 remains stationary under the blocking action of its corresponding limiting plate 232 all the time, and the corresponding top-extending spring 442 of this square sliding sleeve 441 will be compressed and contracted by the moving flattening plate 43. The other square sliding sleeve 441 moves synchronously with the flattening plate 43 and the corresponding pulling plate 445 gradually moves away from the lifting plate 443. The flattening plate 43 drives the pulling plate 445 to move synchronously through the elastic connecting column 444. Correspondingly, when the outer convex arc end of the pulling plate 445 (the pulling plate 445 corresponding to the contracted top-extending spring 442) continues to move after contacting the inclined surface of the corresponding lifting plate 443, it will move towards the direction close to the flattening plate 43 under the action of the inclined surface of the lifting plate 443 and compress the elastic connecting column 444. Furthermore, the pulling plate 445 drives the pressing wheel 446 to move towards the direction close to the flattening plate 43 and cooperate with the flattening plate 43 to clamp the end of the rubber plate. Then, as the flattening plate 43 continues to move, the pressing wheel 446 and the flattening plate 43 cooperate to pull the end of the rubber plate to make the rubber plate move back and forth. After the outer convex arc end of the pulling plate 445 moves from the inclined surface of the lifting plate 443 to the horizontal upper end surface of the lifting plate 443, the pressing wheel 446 and the flattening plate 43 keep clamping the end of the rubber plate to pull the rubber plate, while the pressing wheel 446 corresponding to the pulling plate 445 that gradually moves away from the lifting plate 443 does not clamp the rubber plate.

[0052] When the rubber plate deflects back and forth, the deviation rectifying unit 3 and the flattening unit 4 cooperate to correct its position; specifically, taking the example that the rubber plate deflects forward: when the rubber plate deflects forward, the front deviation rectifying baffle 31 abuts against the front end of the rubber plate and pushes the front end of the rubber plate under the action of the corresponding plurality of elastic pressing rods 325. At the same time, the rear pulling plate 445 drives by the flattening plate 43 and cooperates with the inclined surface of the lifting plate 443 to make the rear pressing wheel 446 and the flattening plate 43 cooperate to clamp the rear end of the rubber plate and pull the rear end of the rubber plate backward. And when the flattening plate 43 moves, it will apply a backward flattening force to the rubber plate. Furthermore, under the cooperation of the pushing of the front deviation rectifying baffle 31, the flattening of the flattening plate 43, and the pulling cooperation of the rear pressing wheel 446 and the flattening plate 43, the position deviation rectification of the rubber plate deflecting forward is completed. The two deviation rectifying baffles 31 continuously move in and out synchronously while cooperating with the back-and-forth movement of the flattening plate 43, forming a dynamic position deviation rectifying mechanism to prevent the rubber plate from deflecting in the front and back directions.

[0053] It should be noted that while the screed plate 43 drives the pull plate 445 and the lifting plate 443 located at the rear to move backward, during the period when the inclined surfaces of the pull plate 445 and the lifting plate 443 cooperate to move the abutting wheel 446 located at the rear upward, the rear end of the rubber plate is always within the range where the abutting wheel 446 and the screed plate 43 cooperate to clamp. The action of the deviation correction baffle 31 pushing the rubber plate can be controlled by means of the existing technology to be synchronized with the action of the abutting wheel 446 and the screed plate 43 cooperating to clamp and pull the rubber plate, so as to efficiently correct the position of the rubber.

[0054] Referring to Figure 2 , Figure 7 and Figure 8 , the guiding unit 5 includes a connecting plate 51 fixedly installed on the right side of the connecting frame 23. A yield plate 52 with an elastic telescopic structure is fixedly installed on the lower side of the connecting plate 51. The lower end of the yield plate 52 is arranged obliquely to the right and is hinged with a square frame 53. Two groups of symmetrically arranged guiding wheel sets 54 are rotatably installed on the upper and lower inner walls of the square frame 53. The guiding wheel set 54 includes a plurality of guiding wheels evenly arranged from left to right. Among them, the square frame 53 is made of a lightweight material, and a torsion spring two is installed at the hinge between the square frame 53 and the yield plate 52. Both the torsion spring two and the elastic structure of the yield plate 52 have relatively small elastic forces, so that the square frame 53 will not press down on the rubber plate.

[0055] The guiding unit 5 is used to prevent the rubber plate from being deflected again. Specifically, when the end of the rubber plate bypasses the lower side of the tension roller 24 and then passes through the square frame 53, when the rubber plate moves, the guiding wheel set 54 can limit the front and rear ends of the rubber plate to prevent the rubber plate from being deflected again. And under the hinge action between the square frame 53 and the yield plate 52 and the action of the elastic telescopic structure of the connecting plate 51, the inclination angle of the square frame 53 can be automatically adjusted adaptively with the change of the inclination angle of the rubber plate between the tension roller 24 and the winding roller assembly, so that the guiding wheels of the guiding wheel set 54 can always limit the front and rear ends of the rubber plate.

[0056] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
