Description

Technical Field

[0001] The utility model relates to the field of auxiliary equipment for tire production, in particular to a laminating assembly and a laminating device for a compressible sound suppression member. Background Art

[0002] When the applicant was developing special equipment for manufacturing silent tires with sound suppression members (such as silent sponges, silent foams, etc.) provided on the inner wall of the tire, it was found that in the existing laminating assemblies for laminating the sound suppression members to the inner wall of the tire, the sound suppression members were directly wound into a roll and placed inside the laminating assembly, and then the laminating assembly with the sound suppression member was moved into the tire for lamination. Since the sound suppression member has a certain thickness, when the sound suppression member is wound into a roll, the volume of the wound sound suppression member is relatively large. When manufacturing tires of different specifications, due to the use of sound suppression members with different thicknesses, the volume of the wound sound suppression member is also different. Therefore, when the existing equipment manufactures tires of different specifications, different-sized laminating assemblies need to be replaced to adapt to the thickness of different sound suppression members. During the replacement of the laminating assembly, cables, air pipes, etc. all need to be reconnected, resulting in a long and complex changeover time. Summary of the Invention

[0025] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings.

[0026] See the appendix Figures 1 to 10 As shown, the present utility model discloses a fitting assembly 1 for a compressible sound suppression member (hereinafter referred to as the fitting assembly. The sound suppression member described in the present utility model can be a soundproof sponge or a soundproof foam, etc. Hereinafter, only the sponge is taken as an example for illustration), including a sponge curling drive source 10 and a sponge curling shaft 11 connected to the sponge curling drive source 10; a backing cloth curling drive source 20 and a backing cloth curling shaft 21 connected to the backing cloth curling drive source 20; further including a speed regulating element 30 and a roller shaft 31 connected. The speed regulating element 30 and the roller shaft 31 can be connected through a coupling 32. A backing cloth roll formed by winding a backing cloth 22 is provided on the backing cloth curling shaft 21. One end of the backing cloth roll is arranged on the backing cloth curling shaft 21, and the other end of the backing cloth roll is arranged on the sponge curling shaft 11 after passing through the roller shaft 31. Further included is a fitting head device 50 for conveying the sponge 41. The fitting head device 50 is arranged on one side of the backing cloth 22 and is on the same side as the rotation center of the sponge curling shaft 11 (the rotation center of the sponge curling shaft 11 described in the present utility model is the center of the sponge curling shaft 11). The fitting head device 50 can be aligned with the part of the backing cloth 22 between the roller shaft 31 and the sponge curling shaft 11, so as to convey the sponge onto the backing cloth 22 between the roller shaft 31 and the sponge curling shaft 11. Optionally, the speed regulating element 30 is an encoder.

[0027] During use, the mat curling drive source 20 drives the mat winding shaft 21 to rotate to unwind the mat 22. The sponge curling drive source 10 drives the sponge winding shaft 11 to rotate, thereby driving the mat 22 to wind around the sponge winding shaft 11. During the process of the mat 22 being transferred from the mat winding shaft 21 to the sponge winding shaft 11, the fitting head device 50 conveys the sponge 41 of a fixed length to the mat 22 on the side close to the sponge winding shaft 11. The sponge winding shaft 11 drives the mat 22 to wind, thereby driving the sponge 41 to wind around the sponge winding shaft 11 together with the mat 22. The sponge winding shaft 11 drives the sponge 41 to curl to compress the sponge 41, and through the winding of the sponge 41 and the mat 22 layer by layer, the sponge 41 is compressed layer by layer, thereby reducing the volume of the sponge 41, enabling the fitting assembly 1 to wind sponges 41 of different specifications and thus being applicable to tires 42 of different specifications. Within a certain range, the different compression degrees of the sponge 41 can be adjusted by adjusting the torque of the sponge curling drive source 10. When the sponge is fitted inside the tire 42, the sponge curling drive source 10 drives the sponge winding shaft 11 to rotate in the direction opposite to the rotation direction during sponge curling, thereby driving the sponge 41 wound around the sponge winding shaft 11 to unwind. The mat curling drive source 20 drives the mat winding shaft 21 to rotate in the direction opposite to the rotation direction during sponge curling to wind up the mat 22. And by setting the speed regulating element 30 and the roller 31, since the sponge 41 is wound together with the mat 22, the curling speed of the sponge 41 is the same as the curling speed of the mat 22. Since the mat 22 is wound through the roller 31, the rotation speed of the roller 31 can reflect the curling speed of the mat 22, that is, the rotation speed of the roller 31 can reflect the curling speed of the sponge 41. When curling the sponge 41, the control system (not shown) sets a curling speed. The speed regulating element 30 detects the rotation speed of the roller 31 and feeds it back to the control system. The control system compares the detection result with the curling speed set by the system and adjusts the sponge curling drive source 10 and the mat curling drive source 20, so that the roller 31 always maintains the same rotation speed during the sponge curling process, that is, the sponge 41 always maintains the same curling speed during the curling process. When unwinding the sponge 41, the control system sets an unwinding speed, and the unwinding speed is matched with the rotation speed of the tire 42. The speed regulating element 30 detects the rotation speed of the roller 31 and feeds it back to the control system. The control system compares the detection result with the unwinding speed set by the system and adjusts the sponge curling drive source 10 and the mat curling drive source 20, so that the roller 31 always maintains the same curling rotation speed during the sponge 41 curling process, that is, the sponge 41 always maintains the same unwinding speed during the unwinding process.That is, the rotation speed of the roller shaft 31 is detected and adjusted in real time by the speed control element 30, so as to ensure that the curling speed is consistent during the curling process of the sponge 41, and the unwinding speed is consistent during the unwinding process of the sponge 41, so that the curling speed during the curling process of the sponge 41 and the unwinding speed during the unwinding process of the sponge 41 will not change due to the change of the diameter of the material roll, and the stretching and stacking during the fitting process of the sponge 41 will not be caused, thereby improving the fitting quality of the sponge 41.

[0028] As Figure 3 shown, as the first embodiment of the present invention, at this time, the fitting head device 50 is arranged between the roller shaft 31 and the sponge curling shaft 11, specifically aligned with the part of the backing cloth 22 between the roller shaft 31 and the sponge curling shaft 11, and the rotation center of the sponge curling shaft 11 and the fitting head device 50 are both located at the lower right of the backing cloth 22. When in use, the backing cloth curling drive source 20 drives the backing cloth curling shaft 21 to rotate clockwise to unwind the backing cloth 22, and the sponge curling drive source 10 drives the sponge curling shaft 11 to rotate clockwise, so as to drive the backing cloth 22 to wind around the sponge curling shaft 11. The fitting head device 50 conveys the sponge 41 to the backing cloth 22 between the roller shaft 31 and the sponge curling shaft 11, and the sponge rotates to the sponge curling shaft 11 together with the backing cloth 22, and is curled and compressed at the sponge curling shaft 11.

[0029] As Figure 4 shown, as the second embodiment of the present invention, at this time, the fitting head device 50 is arranged between the backing cloth curling shaft 21 and the sponge curling shaft 11, specifically aligned with the part of the backing cloth 22 between the roller shaft 31 and the sponge curling shaft 11, and the rotation center of the sponge curling shaft 11 and the fitting head device 50 are both located at the upper left of the backing cloth 22. When in use, the backing cloth curling drive source 20 drives the backing cloth curling shaft 21 to rotate counterclockwise to unwind the backing cloth 22, and the sponge curling drive source 10 drives the sponge curling shaft 11 to also rotate counterclockwise, so as to drive the backing cloth 22 to wind around the sponge curling shaft 11. The fitting head device 50 conveys the sponge 41 to the backing cloth 22 between the roller shaft 31 and the sponge curling shaft 11, and the sponge 41 rotates to the sponge curling shaft 11 together with the backing cloth 22, and is curled and compressed at the sponge curling shaft 11.

[0030] The sponge coiling shaft 11 of the present utility model can be set as a two - part structure that can be connected, so as to place one end of the backing cloth 22 inside the two - part structure to fix the backing cloth 22, or a detachable pressing piece (not shown) can also be provided on the sponge coiling shaft 11 to fix one end of the backing cloth 22. Similarly, the backing cloth coiling shaft 21 can be set as a two - part structure that can be connected to fix the other end of the backing cloth 22, or a detachable pressing piece (not shown) can also be provided on the sponge coiling shaft 11 to fix the other end of the backing cloth 22.

[0031] The backing cloth 22 of the present utility model is reusable. When the sponge 41 is curled, the sponge coiling shaft 11 and the backing cloth coiling shaft 21 rotate in direction A to wind the backing cloth 22 from the backing cloth coiling shaft 21 onto the sponge coiling shaft 11; when the sponge 41 is unwound and attached to the inner wall of the tire 42, the sponge coiling shaft 11 and the backing cloth coiling shaft 21 rotate in the direction opposite to direction A to wind the backing cloth 22 from the sponge coiling shaft 11 onto the backing cloth coiling shaft 21, so as to repeatedly use the backing cloth 22. Since the laminating assembly 1 of the present utility model is used for the production of tires 42 of different specifications, that is, the lengths of the curled sponges 41 are different. If the curling of the sponge 41 starts from a certain position in the middle of the backing cloth roll 22 (that is, at this time, part of the backing cloth 22 has been wound on the sponge coiling shaft 11), there may be a problem that the backing cloth 22 is not long enough during the curling process of the sponge 41, that is, part of the sponge 41 has not been completely wound, and there is no more spare backing cloth 22 on the backing cloth coiling shaft 21. As Figure 3 shown, therefore, in order to ensure that the backing cloth 22 for curling the sponge 41 is sufficient each time, the laminating assembly 1 further includes a zero - position detection switch 60. The zero - position detection switch 60 is arranged opposite to the sponge coiling shaft 11. The zero - position detection switch 60 is used to detect whether the backing cloth 22 on the sponge coiling shaft 11 is in the initial position (when in this initial position, there is almost no backing cloth 22 on the sponge coiling shaft 11). When each unwinding of the sponge 41 is completed and ready to start curling the next sponge 41, if the zero - position detection switch 60 detects that the backing cloth 22 on the sponge coiling shaft 11 is not in the initial position, the sponge curling drive source 10 drives the sponge coiling shaft 11 to rotate, and the backing cloth curling drive source 20 drives the backing cloth coiling shaft 21 to rotate, to rotate the backing cloth 22 on the sponge coiling shaft 11 onto the backing cloth coiling shaft 21 so that the backing cloth 22 on the sponge coiling shaft 11 returns to the initial position before curling, thereby ensuring that the backing cloth 22 is sufficient during the curling process of the sponge 41.

[0032] As Figure 1 and 2As shown in the figure, the laminating head device 50 of the present utility model includes a first pressure roller assembly 51 and a second pressure roller assembly 52. The first pressure roller assembly 51 and the second pressure roller assembly 52 are connected by a connecting rod assembly 53. The first pressure roller assembly 51 includes a first pressure roller shaft 511 and a first pressure roller 512. The first pressure roller 512 is fixedly arranged on the first pressure roller shaft 511 and can rotate synchronously with the first pressure roller shaft 511. The second pressure roller assembly 52 includes a second pressure roller shaft 521 and a second pressure roller 522. The second pressure roller 522 is fixedly arranged on the second pressure roller shaft 521 and can rotate synchronously with the second pressure roller shaft 521. One end of the connecting rod assembly 53 is rotatably arranged on the first pressure roller shaft 511, and the other end of the connecting rod assembly 53 is rotatably arranged on the second pressure roller shaft 521. The first pressure roller 512 and the second pressure roller 522 are linked by a first synchronous transmission device. Specifically, the first synchronous transmission device includes a first synchronous pulley (not shown) and a second synchronous pulley (not shown) linked by a first synchronous belt 541. The first synchronous pulley 541 is fixedly connected to the first pressure roller 512, and the second synchronous pulley is fixedly connected to the second pressure roller 522. It further includes a sponge conveying driving mechanism connected to the first pressure roller shaft 511. The sponge conveying driving mechanism is used to drive the first pressure roller 512 to rotate and drive the second pressure roller 522 to rotate through the first synchronous transmission device, so as to convey the sponge 41.

[0033] Specifically, the sponge conveying driving mechanism includes a conveying driving source 71 and a first transmission device 72 driven by the conveying driving source 71. Preferably, the first transmission device 72 includes a synchronous belt and a synchronous pulley mechanism and a gear transmission mechanism connected. The synchronous pulley includes a third synchronous pulley 7212 and a fourth synchronous pulley 7213 linked by a second synchronous belt 7211. The gear transmission mechanism includes a first gear 7221 and a second gear 7222 meshed. The driving end of the conveying driving source 71 is connected to the third synchronous pulley 7212. The fourth synchronous pulley 7213 and the first gear 7221 are coaxially arranged and can rotate synchronously. The second gear 7222 is fixedly connected to the first pressure roller shaft 511. When the conveying driving source 71 drives the third synchronous pulley 7212 to rotate, it drives the fourth synchronous pulley 7213 to rotate through the second synchronous belt 7211. The fourth synchronous pulley 7213 drives the coaxially arranged first gear 7221 to rotate. The first gear 7221 drives the first pressure roller shaft 511 fixedly connected to the second gear 7222 to rotate through the meshed second gear 7222, so as to realize the function of the laminating head device 50 for conveying the sponge 41.

[0034] As Figure 2As shown, further, the laminating head device 50 further includes a first material guide plate 55 and a second material guide plate 56 arranged in parallel with the first synchronous belt 541. The first material guide plate 55 and the second material guide plate 56 are detachably arranged on the connecting rod assembly 53. When the sponge 41 is conveyed on the laminating head device 50, it is conveyed within the range defined by the first material guide plate 55, the second material guide plate 56, and the first synchronous belt 541. A component for increasing friction (not shown, such as patterns, protrusions, etc.) may be provided on the surface of the first synchronous belt 541 in contact with the sponge 41, so as to increase the grasping force on the sponge 41 and prevent the sponge 41 from slipping during the conveying process. When the sponge 41 is conveyed, it can be conveyed close to the first material guide plate 55 or the second material guide plate 56 for better positioning. Further, a plurality of rows of rotatable rollers 57 may be provided between the first material guide plate 55 and the second material guide plate 56 to further define the conveying space of the sponge 41.

[0035] As Figure 1 As shown, the laminating assembly 1 of the present utility model further includes a first side plate 81, a second side plate 82, and a guard plate 83 which are connected. The first side plate 81 and the second side plate 82 form a material roll accommodating chamber. The sponge curling drive source 10, the backing cloth curling drive source 20, the conveying drive source 71, and the speed regulating element 30 are all arranged on the first side plate 81. Preferably, one ends of the sponge curling drive source 10, the backing cloth curling drive source 20, the conveying drive source 71, and the speed regulating element 30 are all arranged on the side of the first side plate 81 away from the material roll accommodating chamber. The sponge coiling shaft 11, the backing cloth coiling shaft 21, the roller shaft 31, and the first pressing roller shaft 511 all penetrate through the first side plate 81 and are arranged in the material roll accommodating chamber, so that the sponge can be wound and unwound in the material roll accommodating chamber. Further, the other ends of the sponge coiling shaft 11, the backing cloth coiling shaft 21, the roller shaft 31, and the first pressing roller shaft 511 are rotatably arranged on the second side plate 82.

[0036] As Figure 2As shown, the bonding assembly 1 of the present utility model further includes a swing drive mechanism and a push rod assembly 92. The swing drive mechanism is fixedly connected to the connecting rod assembly 53 through the push rod assembly 92, and is used to drive the connecting rod assembly 53 to rotate around the first roller shaft 511, thereby driving the bonding head device 50 to rotate around the first roller shaft 511. After the sponge 41 is wound up by the bonding assembly, the bonding head device 50 rotates around the first roller shaft 511 to receive the bonding head device 50 close to the material roll accommodating chamber, so as to reduce the volume of the entire bonding assembly 1 and make it easier to place the bonding assembly 1 inside the tire 42. When the sponge 41 is bonded to the inner wall of the tire, the swing drive mechanism drives the bonding head device 50 to rotate out of the material roll accommodating chamber for sponge 41 bonding. Preferably, the bonding head device 50 is arranged at one end of the first roller shaft 511 close to the second side plate 82, and there is a position on the second side plate 82 that roughly matches the shape of the bonding head device 50 after folding, so as to fold the bonding head device 50 to this position on the second side plate 82. Since the second side plate 82 is the side that first enters the tire, when the sponge is bonded to the inner wall of the tire by the bonding assembly 1, the position of the second side plate 82 inside the tire 42 is almost flush with the position where the sponge 41 is bonded to one side of the tire, thereby further reducing the space occupied by the bonding assembly 1.

[0037] Specifically, the swing drive mechanism includes a swing drive source 911 and a second transmission device 912 driven by the swing drive source 911. Preferably, the second transmission device 912 is a multi-stage gear transmission mechanism, including a third gear 9122 and a fifth gear 9123 respectively meshed with the fourth gear 9121. The third gear 9122 is connected to the swing drive source 911, and the fifth gear 9123 is rotatably arranged on the first roller shaft 511. The fifth gear 9123 is fixedly connected to the push rod assembly 92. When the swing drive source 911 drives the third gear 9122 to rotate, it drives the fifth gear 9123 meshed with it to rotate, thereby driving the push rod assembly 92 to rotate around the first roller shaft 511, and further driving the connecting rod assembly 53 fixedly arranged with the push rod assembly 92 to rotate around the first roller shaft 511, and then driving the entire bonding head device 50 to rotate around the first roller shaft 511.

[0038] The uniform curling and uniform unwinding of the sponge 41 of the present utility model are realized by detecting the rotation speed of the roller shaft 31 when the pad cloth 22 drives the roller shaft 31 to rotate during the curling and unwinding process of the sponge 41. Therefore, it is necessary to ensure that the pad cloth 22 does not slip on the surface of the roller shaft 31 during the conveying process. Preferably, the surface of the roller shaft 31 is rough, so as to increase the friction between the pad cloth 22 and the roller shaft 31. The surface of the roller shaft 31 can be provided with knurling or protrusions, etc. As Figure 1As shown, further, a rotatable third pressure roller 33 may be provided on the surface of the roller shaft 31. The third pressure roller 33 is in contact with the roller shaft 31 and is used to press the backing cloth 22 tightly against the surface of the roller shaft 31, so that the backing cloth 22 is in full contact with the surface of the roller shaft 31, thereby ensuring that the roller shaft 31 rotates driven by the backing cloth 22 during the conveying process, and further ensuring that the control system can accurately regulate the speed during the curling and unwinding processes of the sponge 41.

[0039] As Figures 5 to 10 is the working principle diagram of the laminating assembly of the present utility model. When the laminating assembly 1 curls the sponge 41, as Figures 5 to 7 shown, the swing drive source 911 drives the laminating head device 50 to rotate around the first pressure roller shaft 511, so that the first synchronous belt 541 of the laminating head device 50 is aligned with the backing cloth 22 between the sponge coiling shaft 11 and the roller shaft 31. The conveying drive source 71 drives the first synchronous belt 541 to rotate in the direction B, and conveys the sponge 41 to the position of the backing cloth 22 along the direction B; meanwhile, the sponge curling drive source 10 drives the sponge coiling shaft 11 to rotate in the direction A, and the backing cloth curling drive source 20 drives the backing cloth coiling shaft 21 to also rotate in the direction A, so that the backing cloth 22 moves from the backing cloth coiling shaft 21 to the sponge coiling shaft 11. When the backing cloth 22 moves, the sponge 41 moves to the sponge coiling shaft 11 together with the backing cloth 22, and the sponge 41 is curled and compressed at the sponge coiling shaft 11; as Figure 8 shown, after the sponge 41 is curled, the swing drive source 911 drives the laminating head device 50 to rotate around the first pressure roller shaft 511, so that the laminating head device 50 is retracted to the second side plate 82, and the volume of the laminating assembly 1 becomes smaller and is placed into the tire 42; as Figure 9 and 10 shown, subsequently, the second pressure roller assembly 52 laminates the sponge 41 to the inner wall of the tire 42. The sponge curling drive source 10 drives the sponge coiling shaft 11 to rotate in the direction opposite to the direction A to unwind the sponge 41, and at the same time, the backing cloth curling drive source 20 drives the backing cloth coiling shaft 21 to rotate in the direction opposite to the direction A to wind the backing cloth 22 onto the backing cloth coiling shaft 21 for recycling. The conveying drive source 71 drives the first synchronous belt 541 to rotate in the direction opposite to the direction B to convey the sponge 41 towards the inner wall of the tire 42, and cooperates with the rotation of the tire 42 to completely laminate the sponge 41 to the inner wall of the tire 42. During the curling and unwinding processes of the sponge 41, the speed regulating element 30 monitors the rotation speed of the roller shaft 31 in real time, compares the detected speed with the preset speed through the control system, and adjusts the backing cloth curling drive source 20 and the sponge curling drive source 10 in real time to regulate the rotation speeds of the sponge coiling shaft 11 and the backing cloth coiling shaft 21, so that the speed of the roller shaft 31 is consistent with the preset speed, thereby ensuring that the curling and unwinding speeds of the sponge 41 are always uniform.

[0040] AsFigure 11 As shown in the figure, the present utility model also provides a fitting device 100 for applying a sound suppression member to the inner wall of a tire, which includes a bracket 200 and a tire fixing device 300 disposed below the bracket 200. The tire fixing device 300 is used to receive the tire 42 conveyed by a conveyor belt or a manipulator, center and fix the tire 42, and then convey the tire 42 to a predetermined fitting position; then, the fitting assembly 1 disposed on the frame 200 receives the sponge 41 and curls the sponge 41, moves the curled sponge 41 to the inner wall of the tire 42 (the front-back or left-right movement of the fitting assembly 1 can be realized through structures such as a ball screw and a slide module), and fits the sponge 41 to the inner wall of the tire. The sponge described in the present utility model can be an ordinary sponge or a sponge with an adhesive backing.
