Description

Technical Field

[0001] The utility model relates to the technical field of film sampling, and specifically, to a TPU film sampling device. Background Art

[0002] TPU is called thermoplastic polyurethane elastomer rubber, which is mainly divided into polyester type and polyether type. It has a wide hardness range (60HA - 85HD), is wear-resistant, oil-resistant, transparent, and has good elasticity. It is widely used in daily necessities, sports goods, toys, decoration materials and other fields. Halogen-free flame-retardant TPU can also replace soft PVC to meet the environmental protection requirements of more and more fields. An elastomer refers to a polymer material with a glass transition temperature lower than room temperature, a fracture elongation rate > 50%, and good resilience after the external force is removed. Polyurethane elastomer is a special and large category in elastomers. The hardness range of polyurethane elastomer is very wide, and the performance range is very wide. Therefore, polyurethane elastomer is a kind of polymer material between rubber and plastic, which can be heated and plasticized, and there is no or very little cross-linking in its chemical structure. Its molecules are basically linear, but there is a certain physical cross-linking. This kind of polyurethane is called TPU. For the mechanical testing of TPU film, the applicable requirements and standards are the same as those of conventional mechanical testing, following ASTM, ISO, GB, etc. In the testing standards, mechanical testing involves tensile strength, elongation at break, 300% modulus, tear strength, etc. When testing these subjects, both transverse and longitudinal directions need to be tested, and samples for testing need to be sampled.

[0003] In the existing process of casting and forming TPU film, it is stretched, wound and flattened, and the film surface is neat. There is a certain tensile force during the winding of TPU film. Moreover, TPU film belongs to a high molecular elastomer. When it is pulled, cut and folded, two reactions will occur to TPU film: 1. Tension release; 2. Molecular movement.

[0004] Secondary crystallization and setting will occur during the long time of stacking, resulting in dead folds that cannot be restored at room temperature.

[0005] In view of the problems in the related art, no effective solution has been proposed yet. Summary of the Utility Model

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] According to an embodiment of the present invention, a TPU film sampling device is provided.

[0030] Embodiment 1;

An auxiliary component 3 is provided on the sampling component 2 for assisting in sampling the TPU film. A controller 4 is provided on one side of the fixed frame 1.

[0032] Embodiment 2;

[0033] As Figures 1 - 9 shown, a TPU film sampling device according to an embodiment of the present invention, the sampling component 2 includes four fixed slots 201 and four movable slots 202;

[0034] The diameters of the four fixed slots 201 are set to 3.5 cm, and the diameters of the four movable slots 202 are set to 10 cm. The fixed slots 201 and the movable slots 202 are symmetrically arranged on the fixed frame 1. A dispensing roller 203 and a winding roller 204 are respectively arranged in the fixed slots 201, and a first guide roller 205 and a second guide roller 206 are respectively arranged in the movable slots 202. Two counters 207 are arranged on the second guide roller 206 through a hoop. The two counters 207 are used to obtain the sampled meterage.

[0039] In practical applications, in order to better ensure the further limiting of the unwinding roller 203 and the winding roller 204, the second threaded rod 302 is rotated by rotating the second adjusting handle 6, and then the second threaded rod 302 drives the adjusting plate 303 to move up and down for adjustment to limit the unwinding roller 203 and the winding roller 204;

[0040] When it is necessary to sample the TPU film on the unwinding roller 203 onto the winding roller 204, the motor 307 is started by the controller 4, then the output shaft of the motor 307 drives the first adjusting wheel 308 to rotate, and then the second adjusting wheel 310 is driven to rotate through the transmission belt 309, so that the first moving wheel 305 rotates, and then the unwinding roller 203 and the winding roller 204 are driven to rotate through the cooperation of the second moving wheels 306 and the auxiliary wheels 304, so that the TPU film on the unwinding roller 203 is wound onto the winding roller 204;

Then, the adjusting seat 313 is moved on the third threaded rod 312, and the second limiting block 315 is moved onto the unwind roller 203 and the winding roller 204. Then, by turning the fourth adjusting handle 8, the fourth threaded rod 314 is driven to rotate, so that the second limiting block 315 moves, thereby performing deviation correction and limiting treatment on the TPU film to be sampled and the sampled TPU film.

That is, when it is necessary to sample the TPU film on the unwind roller 203 to the winding roller 204, the motor 307 is started by the controller 4. Then, the output shaft of the motor 307 drives the first adjusting wheel 308 to rotate, and then the second adjusting wheel 310 is driven to rotate through the transmission belt 309, so that the first moving wheel 305 rotates. Then, the unwind roller 203 and the winding roller 204 are driven to rotate through the cooperation of the second moving wheel 306 and the auxiliary wheel 304, so that the TPU film on the unwind roller 203 is wound onto the winding roller 204. During the rotation process, the sampled TPU film can be guided by the first guide roller 205 and the second guide roller 206. During the guiding process of the second guide roller 206, the length value of the TPU film to be sampled is monitored by the counter 207, so that the sampled meter number can be obtained.
