[0025] The slicing assembly 5 includes a mounting frame 501 disposed on the top of the base 1, a fixed shaft 502 is disposed on the inner wall of the mounting frame 501 via a rotating shaft, and a motor 505 for driving the fixed shaft 502 to rotate is fixedly disposed on one side of the mounting frame 501;

[0026] The outer end of the fixed shaft 502 is provided with a plurality of blades 506 , and the blades 506 are inlaid with cotton cloth 507 . The slicing assembly 5 also includes a cotton rope 504 , and the cotton rope 504 passes through all the cotton cloth 507 . Both ends of the cotton rope 504 are provided with oil storage tanks 4 filled with lubricating oil, and the lubricating oil can be absorbed by the cotton cloth 507 through the cotton rope 504 .

[0027] A blade 506 is installed at the outer end of the fixed shaft 502, and the spacing between any two adjacent blades 506 is equal, so as to cut large pieces of thermoplastic polyurethane elastomer, hereinafter referred to as TPU. The large piece of TPU is placed on the front side of the slicing component 5, and the fixed shaft 502 is driven to rotate by the motor 505 and drives the blade 506. The blade 506 rotates downward and cuts the TPU from the upper side to slice it. During this process, the cotton cloth 507 embedded in the blade 506 contacts the inner wall of the TPU incision during the cutting process, and the rear half of the cotton cloth 507 is provided with a cotton rope 504. The cotton rope 504 absorbs lubricating oil from the inside of the oil storage tank 4 and transports the lubricating oil to the cotton cloth 507. The cotton cloth 507 stained with lubricating oil applies the lubricating oil to the incision of the TPU, thereby playing a lubricating role during the cutting process, reducing the friction of the blade 506 during the cutting process, and making the cutting more labor-saving.

[0028] A detachable cover plate 6 is provided at the top of the oil storage tank 4, and one end of the cotton rope 504 passes through the cover plate 6 and extends to the inside of the oil storage tank 4. One end of the cotton rope 504 is immersed in the lubricating oil inside the oil storage tank 4, so that the cotton rope 504 can absorb the lubricating oil inside the oil storage tank 4 and transport the lubricating oil to the cotton cloth 507.

[0029] The blade 506 is provided with two clamping plates 503 by bolts at one end facing the fixed shaft 502, and the blade 506 is clamped between the two clamping plates 503. The clamping plates 503 are fixed to the outer end of the fixed shaft 502, so that the blade 506 can be detachably installed on the outer end of the fixed shaft 502, and the blade 506 can be disassembled and replaced very conveniently.

[0030] In order to disassemble, replace or overhaul the entire slicing assembly 5, Figure 1 , Figure 4 As shown, the mounting frame 501 is provided with two through slots, and the top of the base 1 is provided with two connecting shafts 8 through a rotating shaft. The top ends of the two connecting shafts 8 penetrate the mounting frame 501 through the through slots and are fixed with a baffle 7, so that the mounting frame 501 is installed and fixed on the top of the base 1.

The mounting frame 501 and the slicing assembly 5 can be fixed as a whole on the top of the base 1 using the baffle 7 and the connecting shaft 8. After the baffle 7 is rotated to a position overlapping with the through slot, the baffle 7 and the connecting shaft 8 can both pass through the through slot, thereby separating the slicing assembly 5 from the base 1.

[0032] In order to fix the TPU during the cutting process, Figure 1 , Figure 3 As shown, a plurality of support frames 2 are fixedly provided on the top of the base 1 , a fixing assembly 3 is provided on the rear side of the support frame 2 , and the thermoplastic polyurethane elastomer to be sliced ​​is fixed on the top of the support frame 2 .

[0034] A plurality of pressing plates 303 are fixedly provided on the front side of the fixed beam 302 . The pressing plates 303 correspond to the support frames 2 one by one and are arranged on the top of the corresponding support frames 2 . The large block of thermoplastic polyurethane elastomer is clamped and fixed on the top of the support frame 2 through the pressing plates 303 .

[0035] The large piece of TPU to be cut is placed on the top of the support frame 2, and the TPU is supported by the support frame 2. Then, the fixed beam 302 is pulled downward by the cylinder 301, thereby driving the pressing plate 303, so that the pressing plate 303 is pressed downward on the top of the TPU, thereby pressing and fixing the TPU. During the cutting process, the blade 506 passes through the gap between the pressing plate 303 and the support frame 2, thereby slicing the TPU.

[0036] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model.
