Description

Technical Field

[0001] The utility model relates to the technical field of calendering technology of a calender, in particular to a calender pad cloth recycling mechanism. Background Art

[0002] Steel cord, the tire's internal skeleton, is made from hundreds of strands of steel cord calendered and coated with rubber. Steel cord is typically quite wide. After being cut and butted at specific angles, the steel cord is formed into components such as the carcass cord and belt plies for tire blank production. Currently, steel cord is double-sidedly laminated with polyethylene film during the calendering process before being wound. This double-layer polyethylene film prevents adhesion between the wound cord layers while maintaining surface adhesion, meeting tire manufacturing process requirements.

[0003] While double-layer film lamination meets production and process requirements, the production cost of a single tire using double-layer film is high. To reduce production costs, some steel cord specifications are now produced with only one side of the film. However, the unlaminated side of the cord comes into contact with multiple rollers on the production equipment during the production process, resulting in a loss of surface adhesion. Inspections have shown a significant difference in surface adhesion between laminated and unlaminated steel cords, making it difficult for unlaminated steel cords to meet process requirements. Utility Model Content

[0004] In view of the shortcomings of the existing technology, a calender pad recycling mechanism is proposed to solve the problem in the above background technology that the cord surface without film is in contact with multiple rollers on the production equipment during the production process, resulting in loss of surface viscosity.

[0005] To achieve the above objectives, the present invention proposes the following technologies:

[0006] A calender pad cloth recycling mechanism includes a stripping component and a bonding component. The stripping component is arranged between a cloth storage station and a curling station to strip the pad cloth on the curtain cloth before curling. The pad cloth is wound on the stripping component and the bonding component. The bonding component is located between the calender and the cooling station to drive the pad cloth stripped by the stripping component to be bonded to the curtain cloth again.

[0007] Furthermore, the stripping assembly includes a first stripping roller located above the curtain, the lower roller and the upper roller of the first stripping roller are respectively located on the inner and outer sides of the padding cloth, and the first stripping roller is matched with the calender linkage line speed to stably strip the padding cloth on the curtain.

[0008] Furthermore, the laminating assembly includes a laminating roller located above the curtain cloth, the padding cloth is located between the curtain cloth and the laminating roller, and the laminating roller is matched with the calender linkage line speed to stably drive the curtain cloth to move while laminating the curtain cloth and the padding cloth.

[0009] Furthermore, it also includes a conveying roller, which conveys the padding stripped from the curtain by the first stripping roller so that the laminating roller can laminarize the padding with the curtain to realize the recycling of the padding.

[0010] Furthermore, a storage groove is provided between the first peeling roller and the conveying roller to store the pad cloth peeled off by the first peeling roller, so that the conveying roller can convey the pad cloth to the laminating roller. The storage groove is located above the cloth storage station, and the width of the storage groove is not less than the width of the pad cloth.

[0011] Furthermore, a guide roller group is provided between the conveying roller and the laminating roller, and the guide roller group guides and tensions the padding conveyed by the conveying roller to ensure that the padding is evenly laminated to the curtain fabric through the laminating roller.

[0012] Furthermore, the guide roller group includes a first guide roller arranged at the same height as the conveying roller, and a floating roller is provided between the first guide roller and the conveying roller. The floating roller can move in a vertical direction to change the tension of the pad cloth to achieve tensioning.

[0013] Furthermore, the guide roller group also includes a second guide roller and a third guide roller located below the first guide roller. The second guide roller and the third guide roller are arranged horizontally at intervals and a correction device is provided between the two to guide the padding during transportation to ensure that the padding and the curtain are evenly fitted.

[0014] Compared with the prior art, the comprehensive effects brought by the utility model include:

[0015] By setting a laminating component to laminate the padding on the surface of the curtain, and using a stripping component to strip the padding before the curtain is rolled up, the cyclic movement of the padding is realized to laminate and strip the single side of the calendered curtain, and the padding is laminated and conveyed with the steel cord. The padding replaces the curtain in direct contact with the guide roller and is stripped before the curtain is rolled up, and then runs to the laminating component for lamination again, realizing cyclic lamination and stripping, effectively reducing the surface viscosity caused by the friction between the steel cord laminated with a single layer of film and the rotating rollers, so that the surface viscosity of the steel cord meets the process requirements, reduces the amount of film used, and greatly reduces the production cost.

[0018] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making any creative efforts are within the scope of protection of the present invention.

[0019] In this document, the directions or positional relationships indicated by terms such as "upper", "lower", "left", "right", and "top" are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0020] like Figure 1 As shown, a calender pad cloth recycling mechanism includes a stripping component and a bonding component. The stripping component is arranged between the cloth storage station 1 and the curling station 2 to strip the pad cloth 4 on the curtain cloth 3 before curling. The pad cloth 4 is wound on the stripping component and the bonding component. The bonding component is located between the calender 5 and the cooling station 6 to drive the pad cloth 4 stripped by the stripping component to bond with the curtain cloth 3 again.

[0021] By setting a bonding component to bond the padding 4 to the surface of the curtain 3, and by using a peeling component to peel the padding 4 before the curtain 3 is rolled up, the cyclic movement of the padding 4 is realized to bond and peel off the single side of the calendered curtain 3, and the padding 4 is bonded and conveyed with the steel cord 3. The padding 4 replaces the curtain 3 in direct contact with the guide roller, and is peeled off before the curtain 3 is rolled up, and is run to the bonding component again for bonding, realizing cyclic bonding and peeling, effectively reducing the surface viscosity caused by the friction between the steel cord 3 bonded with a single layer of film and the rotating rollers, so that the surface viscosity of the steel cord 3 meets the process requirements, reduces the amount of film used, and greatly reduces the production cost.

[0022] Furthermore, due to the use of the recyclable pad 4, there is no need to replace the film, which reduces the labor intensity of the operator.

[0023] Specifically, the calender pad cloth recycling mechanism in this embodiment is based on the calender, cooling drum, cloth storage roller and winding device included in the existing calendering production line. By setting structures such as a peeling component and a bonding component and combining with a control program, the cyclic bonding and peeling actions of the pad cloth 4 on the surface of the curtain cloth 3 are realized.

[0024] Preferably, the padding cloth 4 in this embodiment is made of polyester mesh padding cloth, which has good tear resistance and tensile resistance. The padding cloth 4 is thermoplastically bonded from head to tail to make the whole section of padding cloth 4 ring-shaped. The polyester padding cloth 4 is wound from the bonding section through the cooling drum, cloth storage roller, peeling assembly, etc., and at the same time circulates and is bonded and separated from the steel cord 3 on one side to maintain the surface stickiness of the padding cloth 3 that is not bonded with the film.

[0025] In the calender pad cloth recycling mechanism of this embodiment, the stripping component includes a first stripping roller 7 located above the curtain 3, and the lower roller and upper roller of the first stripping roller 7 are respectively located on the inner and outer sides of the pad cloth 4. The first stripping roller 7 is matched with the calender linkage line speed to stably strip the pad cloth 4 on the curtain 3.

[0026] Specifically, the first peeling roller 7 is arranged above the horizontal conveying section of the curtain 3, and the lower roller of the first peeling roller 7 is tangent to the curtain 3 to ensure that the padding cloth 4 is tightly fitted with the lower roller and thus stably peeled. The upper and lower rollers of the first peeling roller 7 are driven by a variable frequency motor. The rotation speed of the first peeling roller 7 is consistent with the winding speed setting of the winding station 2. When the curtain 3 is wound, the first peeling roller 7 rotates synchronously to peel the padding cloth 4.

[0027] Preferably, in this embodiment, the upper and lower rollers of the first peeling roller 7 are both sponge rollers, with a hard rubber center and a sponge outer layer. The sponge rollers have strong friction and good wear resistance when in contact with the polyester cloth 4. The upper and lower rollers of the first peeling roller 7 are in close contact, and the polyester cloth 4 is peeled off after passing between the upper and lower rollers.

[0028] The calender pad cloth recycling mechanism of this embodiment also includes a conveying roller 9, which conveys the pad cloth 4 peeled off from the curtain 3 by the first peeling roller 7 so that the laminating roller 8 can laminarize the pad cloth 4 and the curtain 3 to achieve the recycling of the pad cloth 4.

[0029] Specifically, the upper and lower rollers of the conveying roller 9 are driven by a variable frequency motor. The rotation speed of the conveying roller 9 is consistent with the conveying speed of the steel cord 3. The upper and lower rollers of the conveying roller 9 are sponge rollers. The center of the roller is hard rubber and the outer layer is wrapped with sponge. The sponge roller has strong friction and good wear resistance in contact with the polyester padding 4, ensuring the smooth transportation of the padding 4.

[0030] In the calendering machine pad cloth recycling mechanism of this embodiment, a storage groove 10 is provided between the first peeling roller 7 and the conveying roller 9 to store the pad cloth 4 peeled off by the first peeling roller 7, so that the conveying roller 9 can convey the pad cloth 4 to the laminating roller 8. The storage groove 10 is located above the cloth storage station 1, and the width of the storage groove 10 is not less than the width of the pad cloth 4.

[0031] A pad storage groove 10 is provided to store the peeled pad 4 for easy transportation via the conveying roller 9. The storage groove 10 is located above the production line platform and is higher than the first peeling roller 7. Preferably, the width of the storage groove 10 is 10 mm larger than the width of the polyester pad 4 to prevent the pad 4 transported via the first peeling roller 7 from being significantly skewed.

[0032] Preferably, a second peeling roller 16 is arranged between the first peeling roller 7 and the storage tank 10. The second peeling roller 16 is located on the side wall of the storage tank 10 close to the first peeling roller 7. The upper and lower rollers of the second peeling roller 16 are driven by a variable frequency motor. The second peeling roller 16 rotates synchronously with the first peeling roller 7 and the winding station 2. When the first peeling roller 7 moves synchronously with the winding, the second peeling roller 16 also moves synchronously to transport the polyester pad 4 peeled off by the first peeling roller 7 to the pad storage tank 10.

[0033] In the calender pad cloth recycling mechanism of this embodiment, the laminating component includes a laminating roller 8 located above the curtain cloth 3, and the pad cloth 4 is located between the curtain cloth 3 and the laminating roller 8. The laminating roller 8 is matched with the calender linkage line speed to stably drive the curtain cloth 3 to move while laminating the curtain cloth 3 and the pad cloth 4.

[0034] Specifically, the laminating roller 8 is located between the calender 5 and the cooling drum, and the upper surface of the calendered curtain fabric 3 is laminated with the padding cloth 4. The surface of the laminating roller 8 is the padding cloth 4, and the outside of the padding cloth 4 is the curtain fabric 3. Through the above-mentioned setting, the laminating roller 8 is tensioned to achieve the laminating of the padding cloth 4 and the curtain fabric 3. The polyester padding cloth 4 is in contact with the steel curtain fabric 3 for lamination, and is driven by the steel curtain fabric 3 to be transported forward, thereby protecting the side of the curtain fabric 3 that is not laminated with the film, and preventing the surface from contacting the subsequent roller group and causing the viscosity to decrease.

[0035] In the calender pad cloth recycling mechanism of this embodiment, a guide roller group is arranged between the conveying roller 9 and the bonding roller 8. The guide roller group guides and tensions the pad cloth 4 conveyed by the conveying roller 9 to ensure that the pad cloth 4 is evenly bonded to the curtain fabric 3 through the bonding roller 8.

[0036] By setting up a guide roller group, multiple guide rollers guide and support the annular pad cloth 4, and transport the polyester pad cloth 4 to the laminating roller 8, so that the polyester pad cloth 4 is tensioned for transportation.

[0037] In the calender pad cloth recycling mechanism of this embodiment, the guide roller group includes a first guide roller 11 set at the same height as the conveying roller 9, and a floating roller 12 is set between the first guide roller 11 and the conveying roller 9. The floating roller 12 can move in the vertical direction to change the tension of the pad cloth 4 to achieve tensioning.

[0038] A floating roller 12 is set between the horizontal conveyor roller 9 and the first guide roller 11. The speed of the conveyor roller 9 is automatically adjusted by the position height of the floating roller 12 on the polyester padding 4, so that the tension of the polyester padding 4 before laminating is uniform and stable, which plays a role in adjusting the tension of the padding 4 between the conveyor roller 9 and the first guide roller 11, and is used to adjust the speed of the conveyor padding 4 and the steel cord 3 before laminating, so that the speeds of the two are consistent and stable; when the floating roller 12 is in a high position, the speed of the conveyor roller 9 is slightly faster, and when it is in a low position, the speed of the conveyor roller 9 is slightly slower; the weight setting of the floating roller 12 and the position of the floating roller 12 are associated with the speed of the conveyor roller 9.

[0039] In the calender pad cloth recycling mechanism of this embodiment, the guide roller group also includes a second guide roller 13 and a third guide roller 14 located below the first guide roller 11. The second guide roller 13 and the third guide roller 14 are arranged horizontally at intervals and a correction device 15 is provided between the two to guide the pad cloth 4 during transportation to ensure that the pad cloth 4 is evenly fitted with the curtain fabric 3.

[0040] The deviation correcting device 15 is located between the second guide roller 13 and the third guide roller 14, and plays the role of correcting the deviation and positioning of the polyester pad 4 being transported before lamination, so that the polyester pad 4 is transported and positioned in the center of the curtain 3 to avoid deviation.

[0041] After the deviation correction, the polyester pad 4 is continuously conveyed to the laminating roller 8 for laminating the pad 4, and the polyester pad 4 is peeled off at the peeling roller, and the laminating and peeling actions form a closed loop.

[0042] Preferably, the deviation-correcting device 15 adopts existing technology, and its specific structure and principle are not described in detail here.
