DETAILED DESCRIPTION

[0027] In order to clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods and in conjunction with the accompanying drawings.

[0028] Reference Figure 1-Figure 3 , double-sided composite molding equipment for asphalt waterproofing membrane, including a frame 1, a tensioning mechanism 2, a limiting mechanism 3, a transmission mechanism 4 and a pressing device 5: The frame 1 is used as a mounting base, on which a first rotating shaft 11 is rotatably arranged, and a feeding roller 111 for providing a carcass 6 is sleeved on the first rotating shaft 11; The tensioning mechanism 2 is used to tension the carcass 6, and includes a movable block 21, a second rotating shaft 22, and a tension roller 23. The movable block 21 is provided with two movable blocks 21, and the two movable blocks 21 are slidably mounted on the frame 1. A first spring 211 is connected between the movable block 21 and the frame 1. Both ends of the second rotating shaft 22 are rotatably connected to the two movable blocks 21, and the tension roller 23 is fixedly sleeved on the second rotating shaft 22. The limiting mechanism 3 is arranged on the frame 1 and is used to limit the rotation of the first rotating shaft 11; The transmission mechanism 4, two ends of which are respectively matched with the second rotating shaft 22 and the limiting mechanism 3, is used to control the limiting mechanism 3 to limit the rotation of the first rotating shaft 11 or release the limiting mechanism 3 from limiting the rotation of the first rotating shaft 11; The pressing device 5 is arranged on the frame 1 and is used for pressing the asphalt onto the carcass 6 .

[0029] In the present invention, the carcass 6 is made of thermoplastic polyolefin material, and the frame 1, tensioning mechanism 2, limiting mechanism 3, transmission mechanism 4 and pressing device 5 cooperate to realize the function of real-time control of the feeding speed according to the tension of the carcass 6 during the processing, thereby achieving the effect of adjusting the tension of the carcass 6, ensuring that the carcass 6 is in a taut state during the processing, avoiding wrinkles and overlaps of the carcass 6 due to slipping or jamming during the processing, thereby solving the problem of uneven asphalt thickness on both sides of the carcass 6 due to wrinkles and overlaps during the processing of the carcass 6.

[0030] The frame 1 is also provided with a rotary driver 12 for providing damping to the first rotating shaft 11. The rotary driver 12 is preferably a retention motor, a stepping motor or an AC motor. The rotary driver 12 and the pressing device 5 are electrically connected to the controller; the two ends of the carcass 6 are respectively connected to the feeding roller 111 and the winding roller (not shown in the figure). During processing, the molding equipment is started, and the controller sends a signal to the rotary driver 12 and the pressing device 5. After the rotary driver 12 is started, damping is applied to the first rotating shaft 11, and the carcass 6 is pulled through the winding roller to control the transmission of the carcass 6. When the carcass 6 passes through the pressing device 5, the pressing device 5 extrude the two sides of the carcass 6 respectively, and extrude the modified asphalt to the two sides of the carcass 6. During the processing, if the tire body 6 becomes loose, the pressure on the tension roller 23 is reduced, and the movable block 21 and the tension roller 23 rise under the elastic force of the first spring 211, further tightening the tire body 6. At the same time, the movable block 21 drives the limiting mechanism 3 through the transmission mechanism 4 to hinder the rotation of the first rotating shaft 11, thereby avoiding wrinkles and overlaps of the tire body 6.

[0031] Reference Figure 4-Figure 7 : The limiting mechanism 3 includes a locking wheel 31 and a movable seat 32; the locking wheel 31 is fixedly mounted on the first rotating shaft 11; the movable seat 32 is slidably mounted on the frame 1, and a return spring 321 is provided on the movable seat 32, and the two ends of the return spring 321 are respectively connected to the movable seat 32 and the frame 1; when the locking wheel 31 cooperates with the movable seat 32, the movable seat 32 will limit the rotation of the locking wheel 31.

[0032] The present invention realizes the function of limiting the rotation of the first rotating shaft 11 through the locking wheel 31 and the movable seat 32, so as to achieve the effect of quickly stopping the feeding of the feeding roller 111, thereby avoiding wrinkles or overlaps of the tire body 6. During the processing, when the tire body 6 is loose, the pressure on the tension roller 23 is reduced, and the movable block 21 and the tension roller 23 rise under the elastic force of the first spring 211, further tightening the tire body 6. At the same time, the movable block 21 overcomes the elastic force of the reset spring 321 through the transmission mechanism 4, drives the movable seat 32 to move toward the locking wheel 31, thereby limiting the rotation of the locking wheel 31, fixing the first rotating shaft 11 through the locking wheel 31, stopping the feeding of the tire body 6, thereby avoiding wrinkles and overlaps of the tire body 6.

[0033] Reference Figure 1 and Figure 4 The transmission mechanism 4 includes a transmission rod 41, which is rotatably mounted on the frame 1, and one end of the transmission rod 41 is provided with a block guide rail 411; the second rotating shaft 22 is slidably matched with the block guide rail 411; when the movable block 21 moves up, it drives the second rotating shaft 22 to move up synchronously, and the second rotating shaft 22 drives the block guide rail 411 to make the end of the transmission rod 41 away from the block guide rail 411 overcome the elastic force of the first spring 211 to push the movable block 21 to move.

[0034] The present invention connects the movable seat 32 and the tension roller 23 through the transmission rod 41 and the block guide rail 411, so as to achieve the effect of automatically limiting the rotation of the feeding roller 111 through the movement of the tension roller 23. During the processing, when the tire body 6 is loose, the pressure on the tension roller 23 is reduced, and the movable block 21 and the tension roller 23 rise under the elastic force of the first spring 211, further tightening the tire body 6. At the same time, the second rotating shaft 22 pushes the transmission rod 41 to rotate through the block guide rail 411. When the transmission rod 41 rotates, the end away from the block guide rail 411 overcomes the elastic force of the return spring 321, pushing the movable seat 32 to move toward the locking wheel 31, so that the movable seat 32 cooperates with the locking wheel 31 to limit the rotation of the locking wheel 31, fixes the first rotating shaft 11 through the locking wheel 31, stops the feeding of the tire body 6, and thus avoids wrinkles and overlaps of the tire body 6.

[0035] Reference Figure 4-Figure 6 : The transmission mechanism 4 includes a guide assembly 42, the guide assembly 42 includes a guide shaft 421, the guide shaft 421 is arranged on the transmission rod 41, and the guide shaft 421 is located at one end of the transmission rod 41 away from the block guide rail 411; an arc guide rail 422 is opened on the frame 1, and the guide shaft 421 slides with the arc guide rail 422.

[0036] The present invention ensures the rotation stability of the transmission rod 41 through the cooperation of the guide shaft 421 and the arc guide rail 422. When the tension roller 23 and the movable block 21 move upward under the elastic force of the first spring 211, the transmission rod 41 is driven to rotate. At this time, the transmission rod 41 drives the guide shaft 421 to rotate, so that the guide shaft 421 slides along the arc guide rail 422, and the movement of the guide shaft 421 is guided and restricted by the arc guide rail 422, so as to ensure the rotation stability of the transmission rod 41, thereby improving the operating stability of the molding equipment and avoiding the rotation of the transmission rod 41 from being offset or misaligned.

[0037] The limiting mechanism 3 in the present invention can adopt the following two structural forms: The first structural form: reference Figure 4-Figure 7: The limiting mechanism 3 includes a first locking assembly 33, which includes a locking block 332 and a second spring 333; the locking block 332 is slidably mounted on the movable seat 32; a locking groove 331 cooperating with the locking block 332 is provided on the locking wheel 31; the two ends of the second spring 333 are respectively connected to the locking block 332 and the movable seat 32.

[0038] The locking groove 331, the locking block 332 and the second spring 333 cooperate to lock the feed roller 111 and prevent the feed roller 111 from rotating. During the molding process, when the tire body 6 becomes loose, the pressure on the tension roller 23 is reduced, and the movable block 21 and the tension roller 23 rise under the elastic force of the first spring 211, further tightening the tire body 6. At the same time, the second rotating shaft 22 pushes the transmission rod 41 to rotate through the block guide rail 411. When the transmission rod 41 rotates, the end away from the block guide rail 411 overcomes the elastic force of the reset spring 321, pushing the movable seat 32 to move toward the locking wheel 31, and the movable seat 32 drives the locking block 33 2, when the locking block 332 contacts the locking wheel 31, it is squeezed by the locking wheel 31, and the second spring 333 contracts. When the locking block 332 is aligned with the locking groove 331, the locking block 332 is inserted into the locking groove 331 under the elastic force of the second spring 333, and then the locking block 332 and the locking groove 331 cooperate to limit the rotation of the locking wheel 31, and the first rotating shaft 11 is fixed by the locking wheel 31, so that the feeding of the tire body 6 is stopped, thereby avoiding wrinkles and overlaps of the tire body 6.

[0039] The second structural form: reference Figure 8-Figure 10 :The limiting mechanism 3 includes a second locking assembly 34, a docking assembly 35 and a transmission control assembly 36; the second locking assembly 34 includes a guide rod 341, a control ring 342 and a third spring 343; the guide rod 341 is installed on the frame 1; the control ring 342 is rotatably connected to the locking wheel 31, and the control ring 342 and the guide rod 341 are slidably matched, and the locking wheel 31 can slide along the axial direction of the first rotating shaft 11; the two ends of the third spring 343 are respectively connected to the control ring 342 and the frame 1; the docking assembly 35 is arranged on the locking wheel 31 and is used to connect the locking wheel 31 and the frame 1; the transmission control assembly 36 is arranged on the movable seat 32 and is used to drive the control ring 342 to move.

[0040] The function of limiting the rotation of the second rotating shaft 22 is achieved by the cooperation of the guide rod 341, the control ring 342 and the third spring 343. The locking wheel 31 cooperates with the first rotating shaft 11 through the keyway, so that the locking wheel 31 can slide along the axial direction of the first rotating shaft 11 while keeping synchronous rotation with the first rotating shaft 11. During the molding process, when the tire body 6 becomes loose, the pressure on the tension roller 23 is reduced, and the movable block 21 and the tension roller 23 rise under the elastic force of the first spring 211 to tighten the tire body 6. At the same time, the second rotating shaft 22 pushes the transmission rod 41 to rotate through the block guide rail 411. When the transmission rod 41 rotates, it overcomes the elastic force of the return spring 321 at the end away from the block guide rail 411, and pushes the movable seat 32 to move toward the locking wheel 31. The movable seat 32 drives the control ring 342 to move toward the frame 1 through the transmission control component 36, and the control ring 342 drives the locking wheel 31 to move. When the locking wheel 31 is tightly fitted with the frame 1, the locking wheel 31 and the frame 1 are connected through the docking component 35, thereby limiting the rotation of the locking wheel 31, fixing the first rotating shaft 11 through the locking wheel 31, stopping the feeding of the tire body 6, and thus avoiding wrinkles and overlaps of the tire body 6.

[0041] Reference Figure 8-Figure 10 : The docking assembly 35 includes a docking column 351 and a fourth spring 352; the docking column 351 is slidably mounted on the locking wheel 31; a docking groove 353 that cooperates with the docking column 351 is provided on the frame 1; both ends of the fourth spring 352 are respectively connected to the docking column 351 and the locking wheel 31.

[0042] The present invention realizes the function of connecting the locking wheel 31 and the frame 1 through the cooperation of the docking column 351, the fourth spring 352 and the docking groove 353. When the tire body 6 is loose, the pressure on the tension roller 23 is reduced, and the movable block 21 and the tension roller 23 rise under the elastic force of the first spring 211, further tightening the tire body 6. At the same time, the second rotating shaft 22 pushes the block guide rail 411, and then pushes the transmission rod 41 to rotate. When the transmission rod 41 rotates, the end away from the block guide rail 411 overcomes the elastic force of the return spring 321, pushing the movable seat 32 to move toward the locking wheel 31. The movable seat 32 drives the control ring 342 to move toward the frame 1 through the transmission control assembly 36. The control ring 342 is driven by the transmission control assembly 36 to move toward the frame 1. The control ring 342 drives the locking wheel 31 to move. When the locking wheel 31 is tightly fitted with the frame 1, the docking column 351 is squeezed by the frame 1, and the fourth spring 352 contracts. As the first rotating shaft 11 and the locking wheel 31 rotate, the docking column 351 is stuck in the docking groove 353 under the elastic force of the fourth spring 352. Through the cooperation between the docking column 351 and the docking groove 353, the rotation of the locking wheel 31 is restricted, and the first rotating shaft 11 is fixed by the locking wheel 31, and the feeding of the tire body 6 is stopped, thereby avoiding wrinkles and overlaps of the tire body 6.

[0043] Reference Figure 8 and Fig. 9: The movable seat 32 is provided with an oblique protrusion 361; the control ring 342 is provided with an oblique notch 362 that cooperates with the oblique protrusion 361; during the movement of the movable seat 32 toward the control ring 342, after the movable seat 32 contacts the control ring 342, the oblique protrusion 361 on the movable seat 32 squeezes the control ring 342, driving the control ring 342 to move toward the frame 1.

[0044] The present invention realizes the function of driving the control ring 342 to move by means of the oblique protrusion 361 and the oblique notch 362 . When the second rotating shaft 22 and the movable block 21 move upward, the second rotating shaft 22 pushes the block guide rail 411, and then pushes the transmission rod 41 to rotate. When the transmission rod 41 rotates, it overcomes the elastic force of the return spring 321 at the end away from the block guide rail 411, and pushes the movable seat 32 to move toward the locking wheel 31. The movable seat 32 drives the oblique protrusion 361 to move synchronously, and the oblique protrusion 361 squeezes the oblique notch 362 on the control ring 342 to drive the control ring 342 to move toward the frame 1. The control ring 342 drives the locking wheel 31 to move. When the locking wheel 31 is tightly fitted with the frame 1, the docking column 351 is squeezed by the frame 1, and the fourth spring 352 contracts. As the first rotating shaft 11 and the locking wheel 31 rotate, the docking column 351 is stuck in the docking groove 353 under the elastic force of the fourth spring 352, and the rotation of the locking wheel 31 is limited by the cooperation of the docking column 351 and the docking groove 353.

[0045] Reference Figure 4 A third rotating shaft 13 is rotatably mounted on the frame 1 , and the third rotating shaft 13 is located between the first rotating shaft 11 and the second rotating shaft 22 . A guide roller 131 is fixedly mounted on the third rotating shaft 13 .

[0046] The direction of the carcass 6 is adjusted by the setting of the third rotating shaft 13 and the guide roller 131, thereby improving the adjustment efficiency of the tension roller 23 on the tensioning degree of the carcass 6, further ensuring the adjustment ability of the tensioning mechanism 2 on the carcass 6, and maintaining the tensioning degree of the carcass 6 during operation to stabilize the processing quality.

[0047] The present invention also provides a method for double-sided composite molding of asphalt waterproofing membrane based on the double-sided composite molding equipment of asphalt waterproofing membrane, comprising the following steps: S1, start the laminating device 5 to perform extrusion lamination on the carcass 6; S2, when the carcass 6 is loose, the movable block 21 and the tension roller 23 tighten the carcass 6 under the elastic force of the first spring 211, and at the same time, the movable block 21 controls the limiting mechanism 3 to start through the transmission mechanism 4, so that the limiting mechanism 3 limits the rotation of the first rotating shaft 11; S3, after the carcass 6 is tightened again, the movable block 21 is reset, and the limiting mechanism 3 releases the rotation restriction on the first rotating shaft 11; S4. When the carcass 6 becomes loose again, steps S2-S3 are repeated until the double-sided composite molding of the asphalt waterproofing membrane is completed.
