Description

Technical Field

[0001] The invention relates to the technical field of rubber plate production, in particular to fireproof rubber plate production and conveying equipment. Background Art

[0002] Fire-resistant rubber sheet (hereinafter referred to as rubber sheet) is a functional material with rubber as the matrix, prepared by adding flame retardants and high-temperature resistant fillers. It has excellent flame retardancy, high-temperature resistance and insulation properties, and is widely used in building fire isolation, rail transit interior, power equipment protection and other fields. Rubber sheet is usually made through mixing, calendering, vulcanization and cooling processes. Finally, the finished rubber sheet is rolled and packaged by conveying equipment to facilitate subsequent transportation and storage.

[0003] When conveying rubber sheets, the finished rubber sheets are usually conveyed to the winding rollers through conveyor rollers. After the rubber sheets are wound to a preset roll diameter, they are cut, rolled and packaged manually or by roll-changing equipment. A tensioning roller is provided between the conveyor roller and the winding roller to tension the rubber sheets, ensuring that the layers of the rubber sheets are tightly fitted, which is convenient for subsequent packaging and transportation.

[0004] However, the conveying process of the above-mentioned rubber sheets has the following problems: 1. The rubber sheets may be skewed: The rubber sheets may be skewed in the front-to-back direction during the conveying process, resulting in uneven edges of the rolled sheets after winding, which in turn affects the subsequent packaging of the rubber sheets, and may even require the machine to be stopped and the rubber sheets to be corrected, resulting in reduced conveying efficiency of the rubber sheets.

[0005] 2. Excessive tensioning of the rubber sheet: Since the rubber sheet has a certain thickness, the radius of the rubber sheet roll increases rapidly. As the rolling radius of the rubber sheet increases, the tensioning force of the tensioning roller on the rubber sheet also increases, resulting in the risk of the rubber sheet being overstretched or even broken, thereby reducing the quality of the rubber sheet.

DETAILED DESCRIPTION

[0029] The embodiments described below are exemplary and are only used to explain the present invention, and are not to be construed as limiting the present invention. If no specific techniques or conditions are specified in the embodiments, the techniques or conditions described in the literature in the art or the product instructions shall be followed.

[0030] See Figure 1 、 Figure 2 and Figure 8 A fire-proof rubber sheet production and conveying equipment includes a conveying and reeling machine 1, a tensioning unit 2 for tensioning the rubber sheet is installed on the conveying and reeling machine 1, a correction unit 3 for correcting the front and rear ends of the rubber sheet is installed on the tensioning unit 2, a smoothing unit 4 for smoothing the rubber sheet is installed on the left side of the tensioning unit 2, and a guide unit 5 for preventing the rubber sheet from secondary deflection 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 upper left end of the base, and the winding roller assembly is installed at the upper right end 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 up the rubber sheet. The winding roller of the winding roller assembly is detachably mounted on the winding roller assembly so that the rubber sheet wound to a preset diameter can be changed manually or by an external winding machine.

[0032] The present invention is used for conveying rubber sheets, and as the roll diameter of the rolled rubber sheet increases, the present invention can simultaneously reduce the tensioning force on the rubber sheet, thereby preventing the rubber sheet from being overstretched or even broken, thereby ensuring the quality of the rubber sheet. At the same time, the present invention can also prevent the rubber sheet from being deflected in the front-to-back direction, ensuring that the edges of the rolled material are flush after being rolled, thereby improving the conveying efficiency of the rubber sheet.

[0033] Specifically, the end of the rubber sheet is first passed through the conveying roller assembly, the tensioning unit 2 and the winding roller assembly of the conveying and winding machine 1 in sequence, and the end of the rubber sheet is fixed to the winding roller of the winding roller assembly through the existing fixing structure. Then, the tensioning unit 2 is controlled to tension the rubber sheet downward and adjust the tensioning force applied to the rubber sheet. Then, 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 smoothing unit 4 and the correction unit 3 cooperate to prevent the rubber sheet from deflecting in the front-to-back direction, and the guide unit 5 can prevent the rubber sheet from deflecting twice, so that the edges of the roll wound by the winding roller assembly are flush, and as the roll diameter of the wound rubber sheet increases, the tensioning force applied to the rubber sheet by the tensioning unit 2 is synchronously reduced. When the rubber sheet is wound to the preset roll diameter, the winding roller of the winding roller assembly that winds the rubber sheet is removed manually or by an external roll changing machine, and a new winding roller is replaced. The above operation is repeated to continuously convey and wind the rubber sheet.

[0034] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 8The tensioning unit 2 includes a gantry 21 fixedly installed in the middle of the upper end of the base. A U-shaped connecting frame 23 is installed on the inner top wall of the gantry 21 through a tensioning adjustment group 22. Tensioning rollers 24 are installed on the front and rear sides of the connecting frame 23 for rotation. 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 motor output shaft and the tensioning roller 24 are fixedly connected, and the motor is fixedly connected to the connecting frame 23 through the motor frame, and the tensioning roller 24 is driven to rotate by starting the motor.

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

[0037] See 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, and a lower pressure 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 pressure plate 222 and the gantry 21, and the lower end of the lower pressure plate 222 is connected to the upper side of the connecting frame 23 through a plurality of elastic tensioning rods 224 evenly arranged front and back, and the elastic tensioning rods 224 are a telescopic structure; wherein, the front and rear sides of the connecting frame 23 are connected to the gantry 21 for sliding up and down through the guide plate.

[0038] The tensioning adjustment group 22 is used to adjust the tensioning force of the tensioning roller 24 on the rubber sheet; specifically, the hydraulic rod 221 is controlled to move the lower pressure plate 222 downward, and then finally drives the tensioning roller 24 to move downward. The tensioning roller 24 tensions the rubber sheet downward. As the lower pressure plate 222 moves downward, the elastic tensioning rod 224 is compressed. The compression amount of the elastic tensioning rod 224 is proportional to the elastic force it generates (following Hooke's law F = kxTherefore, by controlling the compression of the elastic tensioning rod 224, the tensioning force exerted by the tensioning roller 24 on the rubber sheet can be adjusted. As the roll diameter of the wound rubber sheet increases, the hydraulic rod 221 is controlled to synchronously move the lower pressure plate 222 upward, reducing the compression of the elastic tensioning rod 224 and, in turn, the tensioning force exerted by the tensioning roller 24 on the rubber sheet. This prevents the rubber sheet from being overstretched or even broken, thereby ensuring its quality. It should be noted that sensor feedback can be used to precisely respond to changes in roll diameter, dynamically adjusting the position of the lower pressure plate 222 to maintain the appropriate compression of the elastic tensioning rod 224.

[0039] See Figure 2 、 Figure 4 and Figure 8 The correction unit 3 includes two correction baffles 31 symmetrically arranged front and back on the outside of the tensioning roller 24 , and an extrusion group 32 is connected between the two correction baffles 31 and the tensioning roller 24 on opposite sides.

[0040] See Figure 1 、 Figure 3 and Figure 8 The smoothing 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 be tilted to the left and is set to an elastic telescopic structure. The lower end of the inclined plate 42 is hinged with a smoothing plate 43, and the front and rear ends of the smoothing plate 43 are both equipped with a pulling group 44 for pulling the end of the rubber plate; wherein, a torsion spring 1 is installed at the hinge of the inclined plate 42 and the smoothing plate 43, and the torsion spring 1 and the elastic telescopic structure of the inclined plate 42 both have a small elastic force, so that the smoothing plate 43 will not squeeze the rubber plate downward.

[0041] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 8 When the tension roller 24 rotates, the tension roller 24 drives the deflection-correcting baffle 31 to rotate synchronously through the extrusion group 32, and the extrusion group 32 drives the two deflection-correcting baffles 31 to move back and forth synchronously (i.e., move back and forth), thereby starting the reciprocating group 41 to drive the smoothing plate 43 to move back and forth through the inclined plate 42, so that the smoothing plate 43 smoothes the rubber sheet to ensure that the surface of the rubber sheet is flat, and the pulling group 44 arranged along the moving direction of the smoothing plate 43 can synchronously pull the end of the rubber sheet to ensure that the rubber sheet is thoroughly smoothed.

[0042] When the rubber sheet does not deflect in the front-to-back direction, when the two correcting baffles 31 move toward each other to the extreme position, the two correcting baffles 31 only slightly contact the front and rear ends of the rubber sheet, which plays the role of maintaining the continuous limit of the rubber sheet in the future; when the rubber sheet deflects in the front-to-back direction, take the forward deflection of the rubber sheet as an example: when the rubber sheet deflects forward, the correcting baffle 31 located in the front can push the front end of the rubber sheet when moving toward the middle of the tensioning roller 24, and at the same time cooperate with the smoothing operation of the smoothing plate 43 and the pulling operation of the pulling group 44 located at the rear to complete the position correction of the rubber sheet, thereby realizing continuous dynamic position correction of the rubber sheet.

[0043] See Figure 4 The cam 324 is pressed against the top of the cam 326 to push the cam 328 in the direction of the left end of the cam 329, so that the cam 328 can be locked to the stop position when the cam 329 is locked.

[0044] It should be noted that the elastic extrusion rod 325 is provided with a large elastic force. When the correcting baffle 31 contacts the deflected end of the rubber plate, the correcting baffle 31, under the elastic force of the corresponding multiple elastic extrusion rods 325, exerts a pushing force on the end of the rubber plate, which can overcome the tensioning force acting on the rubber plate, the friction between the rubber plate and the tensioning roller 24, and the elastic force of the rubber plate itself, thereby ensuring that the correcting baffle 31 can push the deflected end of the rubber plate.

[0045] When the cam 324 is in the unlock state, the locking cam 325 is in the unlock state, and the locking cam 326 is in the unlock state, so that the locking cam 326 is locked. When the cam 325 is in the forward position, the cam 326 is in the forward position and the cam 327 is in the forward position, so that the cam 326 will not move in the reverse direction and the cam 328 will not move in the reverse direction.

[0046] See Figure 3 The reciprocating group 41 includes a reciprocating plate 411 that is slidably mounted 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 threaded fitting, and the threaded rod 412 is rotatably connected to the connecting frame 23. The front end of the threaded rod 412 passes through the connecting frame 23 and is fixedly connected to the output shaft of the reciprocating motor 413 that is fixedly mounted on the outside of the connecting frame 23.

[0047] The reciprocating group 41 drives the smoothing plate 43 to move back and forth through the inclined plate 42; specifically, the reciprocating motor 413 is started to drive the threaded rod 412 to rotate back and forth, so that the threaded rod 412 drives the reciprocating plate 411 to move back and forth through the threaded engagement, and then the reciprocating plate 411 drives the smoothing plate 43 to move back and forth through the inclined plate 42.

[0048] See Figure 3 、 Figure 5 、 Figure 6 and Figure 8The pulling assembly 44 comprises a square sleeve 441 that slides forward and backward over the end of the smoothing plate 43. A spring 442 is connected between the inner wall of the sleeve 441 and the end surface of the smoothing plate 43. An L-shaped lifting plate 443 is fixedly mounted on the lower end of the sleeve 441. The two lifting plates 443 have inclined surfaces on their opposing sides. Two symmetrically arranged elastic connecting posts 444 are fixedly mounted on the lower end of the smoothing plate 43. These posts are telescopic structures, and pulling plates 445 are fixedly mounted on their lower ends. Opposing sides of the two pulling plates 445 are rotatably connected to retaining wheels 446. Friction plates are installed at the rotatable connection between the pulling plates 445 and retaining wheels 446. The opposing sides of the two pulling plates 445 are each configured as an outwardly convex arc. It should be noted that the friction plates exhibit low friction.

[0049] When the pressure wheel 446 and the smoothing plate 43 cooperate to clamp the end of the rubber plate and pull the rubber plate, under the action of the friction plate, the rotation connection between the pressure wheel 446 and the pulling plate 445 is subjected to a certain resistance, so that the pressure wheel 446 can stably cooperate with the smoothing plate 43 to apply a certain pulling force to the clamped rubber plate end; when the rubber plate is not deflected, the pressure wheel 446 does not cooperate with the smoothing plate 43 to clamp the rubber plate, and the pressure wheel 446 only contacts the rubber plate. Then, during the period when the pressure wheel 446 moves back and forth with the smoothing plate 43 (in this process, the pulling plate 445 does not contact the inclined surface of the lifting plate 443), since the rubber plate itself has a certain elasticity and there is friction between the pressure wheel 446 and the rubber plate, the friction at the rotation connection between the pressure wheel 446 and the pulling plate 445 is overcome, and the pressure wheel 446 will rotate, thereby preventing the rubber plate that was not deflected from being deflected due to the movement of the pressure wheel 446.

[0050] See Figure 3 Two symmetrically arranged limit plates 232 are fixedly installed on the left side of the connecting frame 23, and the opposite sides of the two limit plates 232 are in contact with their corresponding square sliding sleeves 441.

[0051] See Figure 3 、 Figure 5 、 Figure 6 and Figure 8The pulling group 44 is used to pull the end of the rubber sheet; specifically, it passes the end of the rubber sheet around the underside of the tensioning roller 24, allowing the rubber sheet to pass between the pulling plate 445 and the smoothing plate 43. At this point, the retaining wheel 446 and the rubber sheet do not come into contact. As the smoothing plate 43 reciprocates back and forth, the square sleeve 441 in the direction of movement of the smoothing plate 43 remains stationary due to the blocking action of its corresponding limit plate 232. The extension spring 442 corresponding to this square sleeve 441 is squeezed and contracted by the moving smoothing plate 43, while the other square sleeve 441 moves synchronously with the smoothing plate 43, and its corresponding pulling plate 445 gradually moves away from the lifting plate 443. The stroking plate 43 drives the pulling plate 445 to move synchronously through the elastic connecting column 444. When the convex arc end of the corresponding pulling plate 445 (the pulling plate 445 corresponding to the contracted extension spring 442) contacts the corresponding lifting plate 443 inclined surface and continues to move, it will move toward the stroking plate 43 under the action of the inclined surface of the lifting plate 443 and compress the elastic connecting column 444, thereby causing the pulling plate 445 to drive the pressing wheel 446 to move toward the stroking plate 43 and mate with the stroking plate 43. The end of the rubber sheet is clamped together, and then as the smoothing plate 43 continues to move, the clamping wheel 446 and the smoothing plate 43 cooperate to pull the end of the rubber sheet to make the rubber sheet move forward and backward. After the 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 clamping wheel 446 and the smoothing plate 43 maintain the clamping of the end of the rubber sheet to pull the rubber sheet, and the clamping wheel 446 corresponding to the pulling plate 445 that gradually moves away from the lifting plate 443 does not clamp the rubber sheet.

[0052] When the rubber sheet deflects forward and backward, the correction unit 3 and the smoothing unit 4 cooperate to correct its position; specifically, take the rubber sheet deflecting forward as an example: when the rubber sheet deflects forward, the correction baffle 31 located in the front contacts the front end of the rubber sheet and pushes the front end of the rubber sheet under the action of the corresponding multiple elastic extrusion rods 325. At the same time, the pulling plate 445 located at the rear, driven by the smoothing plate 43, cooperates with the inclined surface of the lifting plate 443 to make the clamping wheel 446 located at the rear and the smoothing plate 43 cooperate to clamp the rear end of the rubber sheet and pull the rear end of the rubber sheet backward. When the smoothing plate 43 moves, it will apply a backward smoothing force to the rubber sheet, and then, under the push of the correction baffle 31 located in the front, the smoothing of the smoothing plate 43, and the pulling cooperation of the clamping wheel 446 located at the rear and the smoothing plate 43, the position correction of the rubber sheet deflected forward is completed. The two deviation-correcting baffles 31 continuously and synchronously move inward and outward and cooperate with the forward and backward movement of the smoothing plate 43 to form a dynamic position deviation-correcting mechanism to prevent the rubber plate from deflecting in the forward and backward directions.

[0053] It should be noted that the smoothing plate 43 drives the pulling plate 445 and the lifting plate 443 located at the rear to move backward. The inclined surfaces of the pulling plate 445 and the lifting plate 443 cooperate to cause the rearward pressure roller 446 to move upward, while the rear end of the rubber sheet is always within the clamping range of the pressure roller 446 and the smoothing plate 43. By utilizing existing technology, the movement of the correcting baffle 31 pushing the rubber sheet can be synchronized with the movement of the pressure roller 446 and the smoothing plate 43 to clamp and pull the rubber sheet, thereby efficiently correcting the position of the rubber sheet.

[0054] See Figure 2 、 Figure 7 and Figure 8 The guide unit 5 includes a connecting plate 51 fixedly installed on the right side of the connecting frame 23, and 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 tilted to the right and hinged with a square frame 53. Two groups of guide wheel groups 54 symmetrically arranged front and back are rotatably installed on the upper and lower inner walls of the square frame 53. The guide wheel group 54 includes a plurality of guide wheels evenly arranged left and right; wherein, the square frame 53 is made of lightweight material, and a torsion spring 2 is installed at the hinge of the square frame 53 and the yield plate 52. The torsion spring 2 and the elastic structure of the yield plate 52 both have a small elastic force, so that the square frame 53 will not squeeze the rubber plate downward.

[0055] The guide unit 5 is used to prevent the rubber sheet from being deflected twice. Specifically, after the end of the rubber sheet is passed around the lower side of the tensioning roller 24, the end of the rubber sheet is passed through the square frame 53. When the rubber sheet moves, the guide wheel group 54 can limit the front and rear ends of the rubber sheet to prevent the rubber sheet from being deflected twice. Under the hinged action of the square frame 53 and the yield plate 52 and the elastic telescopic structure of the connecting plate 51, the inclination angle of the square frame 53 can be adaptively and automatically adjusted as the inclination angle of the rubber sheet between the tensioning roller 24 and the winding roller assembly changes, so that the guide wheels of the guide wheel group 54 can always limit the front and rear ends of the rubber sheet.

[0056] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
