[0001] This utility model belongs to the field of film processing technology, specifically a calender for processing thermoplastic polyurethane films. Background Technology

[0002] Thermoplastic polyurethane film is a film material made of thermoplastic polyurethane elastomer. Thermoplastic polyurethane elastomer is an elastomer that combines the properties of rubber and plastic. It is made by polymerization of diisocyanate, polyol, and chain extender. A calender is an indispensable key piece of equipment in the processing of thermoplastic polyurethane film; its main function is to extrude and stretch the thermoplastic polyurethane material through calender rolls to form a film with a certain thickness and width.

[0003] In the prior art, the calendering rolls of some calenders are mounted on fixed supports, and can only be adjusted slightly by a limited mechanical structure. This makes it difficult to meet the processing requirements of films of different thicknesses. This design limits the versatility and adaptability of the calender and makes it unable to flexibly handle a variety of production tasks.

[0004] Therefore, this utility model provides a calender for processing thermoplastic polyurethane films. Utility Model Content

[0005] To address the shortcomings of existing technologies and solve the problem that some calenders have calender rolls mounted on fixed supports, which can only be adjusted by a limited mechanical structure, making it difficult to meet the processing requirements of films of different thicknesses, this design limits the versatility and adaptability of the calender and makes it unable to flexibly handle a variety of production tasks.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A calendering machine for processing thermoplastic polyurethane film, comprising a base plate, wherein a calendering mechanism is provided on the base plate, and the calendering mechanism includes:

[0007] A calendering assembly includes a pair of first sliding grooves on a base plate, a first sliding block slidably connected within each first sliding groove, a vertical plate fixedly connected to the top of each first sliding block, a first rotating rod rotatably connected to the vertical plate via a first rotating hole, a first locking block fixedly connected to one end of the first rotating rod, a fixed roller placed between the pair of first locking blocks, a second sliding groove on the vertical plate, a second sliding block connected within each second sliding groove, a second rotating rod rotatably connected to the second sliding block via a second rotating hole, a second locking block fixedly connected to one end of the second rotating rod, a movable roller placed between the pair of second locking blocks, a first motor fixedly connected to the side wall of the vertical plate via a first L-shaped rod, the output end of the first motor being drivenly connected to the first rotating rod, and a lifting assembly for driving the movable roller to rise and fall on the vertical plate.

[0008] An adjustment component, located at the bottom of the base plate, is used to adjust the position of a pair of first sliding blocks;

[0009] Support components are installed on top of the base plate to support a pair of upright plates.

[0010] Preferably, the support assembly includes a pair of concave frames fixed to the top of the base plate, a support rod fixed between the opposite sidewalls of the pair of concave frames, and a pair of upright plates slidably connected to the pair of support rods through guide holes.

[0011] Preferably, the lifting assembly includes a first bevel gear fixedly connected to a first rotating rod, an electric push rod fixedly connected to the side wall of the upright plate by a fixing block, and a second bevel gear fixedly connected to the base end of the electric push rod, the second bevel gear meshing with the first bevel gear.

[0012] Preferably, a third bevel gear is fixedly connected to the telescopic end of the electric actuator, and a fourth bevel gear is fixedly connected to the second rotating rod, wherein the fourth bevel gear meshes with the third bevel gear.

[0013] Preferably, the adjustment assembly includes a second motor fixed to the bottom of the base plate via a pair of second L-shaped rods, the output end of the second motor is provided with a drive rod, and the top end of the drive rod is fixed with an adjustment rod.

[0014] Preferably, both ends of the adjusting rod are rotatably connected to connecting rods via a first rotating shaft, and the end of the connecting rod away from the adjusting rod is rotatably connected to the bottom of the first sliding block via a second rotating shaft.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. The calender for processing thermoplastic polyurethane film of this utility model, by rotating a first rotating rod, drives an electric push rod to rotate through a first bevel gear and a second bevel gear. The rotation of the electric push rod, in turn, drives a second rotating rod to rotate through a third bevel gear and a fourth bevel gear. This causes the moving roller and the fixed roller to rotate relative to each other to calender the film. The electric push rod can extend and retract, and the distance between the moving roller and the fixed roller can be adjusted. This solves the problem in the prior art that it is difficult to meet the processing needs of films of different thicknesses. This design limits the versatility and adaptability of the calender and makes it unable to flexibly cope with various production tasks.

[0017] 2. The calender for processing thermoplastic polyurethane film of this utility model uses a motor to drive a drive rod to rotate, which in turn causes a fixed adjusting rod to rotate. This allows the first sliding block to slide in the first sliding groove via a connecting rod, thereby moving a pair of upright plates relative to each other. Then, the fixed roller and the moving roller are clamped and fixed by the first and second locking blocks, which makes it convenient for workers to replace the moving roller and the fixed roller.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figures 1 to 4As shown in the figure, a calendering machine for processing thermoplastic polyurethane film according to an embodiment of the present invention includes a base plate 1, on which a calendering mechanism is provided. The calendering mechanism includes a calendering assembly, including a pair of first sliding grooves 2 opened on the base plate 1, a first sliding block 3 slidably connected in the first sliding grooves 2, a vertical plate 4 fixedly connected to the top of the first sliding block 3, a first rotating rod 5 rotatably connected to the vertical plate 4 through a first rotating hole, a first locking block 6 fixedly connected to one end of the first rotating rod, a fixed roller 7 placed between the pair of first locking blocks 6, and a second sliding groove 8 opened on the vertical plate 4, the second sliding groove 8 being connected to... There is a second sliding block 9, and a second rotating rod 10 is rotatably connected to the second sliding block 9 through a second rotating hole. A second locking block 11 is fixed to one end of the second rotating rod 10. A moving roller 12 is placed between a pair of second locking blocks 11. A first motor 13 is fixed to the side wall of the upright plate 4 through a first L-shaped rod. The output end of the first motor 13 is driven and connected to the first rotating rod 5. The upright plate 4 is provided with a lifting assembly for driving the moving roller 12 to rise and fall; an adjustment assembly is provided at the bottom of the base plate 1 for adjusting the position of a pair of first sliding blocks 3; and a support assembly is provided at the top of the base plate 1 for supporting a pair of upright plates 4.

[0026] During operation, the movable roller 12 can be moved by a pair of second sliding blocks 9, which makes it difficult to meet the processing requirements of films of different thicknesses. This design limits the versatility and adaptability of the calender and makes it unable to flexibly cope with various production tasks.

[0027] The support assembly includes a pair of concave frames 14 fixed to the top of the base plate 1, support rods 15 fixed between the opposite side walls of the pair of concave frames 14, and a pair of upright plates 4 slidably connected to the pair of support rods 15 through guide holes.

[0028] During operation, a pair of support rods 15 provide limiting support for a pair of upright plates 4, thereby improving the stability of the pair of upright plates 4.

[0029] The lifting assembly includes a first bevel gear 16 fixedly connected to the first rotating rod 5, an electric push rod 17 fixedly connected to the side wall of the upright plate 4 by a fixing block, a second bevel gear 18 fixedly connected to the base end of the electric push rod 17, and the second bevel gear 18 meshing with the first bevel gear 16.

[0030] The telescopic end of the electric actuator 17 is fixedly connected to a third bevel gear 19, and a fourth bevel gear 20 is fixedly connected to the second rotating rod 10. The fourth bevel gear 20 meshes with the third bevel gear 19.

[0031] During operation, the rotation of the first rotating rod 5 drives the electric push rod 17 to rotate via the transmission of the first bevel gear 16 and the second bevel gear 18. The rotation of the electric push rod 17, in turn, drives the second rotating rod 10 to rotate via the transmission of the third bevel gear 19 and the fourth bevel gear 20. This causes the moving roller 12 and the fixed roller 7 to rotate relative to each other to calender the film. The electric push rod 17 can extend and retract, and the distance between the moving roller 12 and the fixed roller 7 can be adjusted. This solves the problem that the existing technology is unable to meet the processing requirements of films of different thicknesses. This design limits the versatility and adaptability of the calender and makes it unable to flexibly cope with various production tasks.

[0032] The adjustment assembly includes a second motor 21 fixed to the bottom of the base plate 1 by a pair of second L-shaped rods. The output end of the second motor 21 is provided with a drive rod 22, and the top end of the drive rod 22 is fixed with an adjustment rod 23.

[0033] Both ends of the adjusting rod 23 are rotatably connected to the connecting rod 24 via the first rotating shaft. The end of the connecting rod 24 away from the adjusting rod 23 is rotatably connected to the bottom of the first sliding block 3 via the second rotating shaft.

[0034] During operation, the motor drives the drive rod 22 to rotate, which in turn rotates the fixed adjusting rod 23. This allows the first sliding block 3 to slide within the first sliding groove 2 via the connecting rod 24, thereby causing the pair of upright plates 4 to move relative to each other. Then, the first locking block 6 and the second locking block 11 clamp and fix the fixed roller 7 and the moving roller 12, making it convenient for workers to replace the moving roller 12 and the fixed roller 7.

[0035] Working principle: The movable roller 12 can be moved by a pair of second sliding blocks 9, which is difficult to meet the processing requirements of films of different thicknesses. This design limits the versatility and adaptability of the calender and cannot flexibly deal with the problem of multiple production tasks.

[0036] By using a pair of support rods 15 to limit and support a pair of upright plates 4, the stability of the pair of upright plates 4 can be improved.

[0037] Rotating the first rotating rod 5 drives the electric push rod 17 to rotate via the transmission of the first bevel gear 16 and the second bevel gear 18. The rotation of the electric push rod 17, in turn, drives the second rotating rod 10 to rotate via the transmission of the third bevel gear 19 and the fourth bevel gear 20. This causes the moving roller 12 and the fixed roller 7 to rotate relative to each other to calender the film. The electric push rod 17 can extend and retract, and the distance between the moving roller 12 and the fixed roller 7 can be adjusted. This solves the problem that the existing technology cannot meet the processing requirements of films of different thicknesses. This design limits the versatility and adaptability of the calender and cannot flexibly cope with various production tasks.

[0038] The motor drives the drive rod 22 to rotate, which in turn rotates the fixed adjustment rod 23. This allows the first sliding block 3 to slide in the first sliding groove 2 via the connecting rod 24, thereby driving the pair of upright plates 4 to move relative to each other. Then, the first locking block 6 and the second locking block 11 clamp and fix the fixed roller 7 and the moving roller 12, making it convenient for workers to replace the moving roller 12 and the fixed roller 7.
