[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformation under very small external force. It can return to its original shape after the external force is removed. Rubber is divided into natural rubber and synthetic rubber according to the raw materials. According to the form, it is divided into block raw rubber, latex, liquid rubber and powdered rubber; latex is a colloidal aqueous dispersion of rubber; liquid rubber is a rubber oligomer, which is generally a viscous liquid before vulcanization; powdered rubber is latex processed into powder to facilitate batching and processing. Rubber products are widely used in various aspects of industry or life. Rubber can be formed into rubber sheets by plasticating, mixing, calendering or extruding, which need to be cut for subsequent use;

[0003] In the prior art, when cutting a rubber sheet, the rubber sheet is usually manually moved to a cutting position and then a cutting device is controlled to cut the rubber sheet. However, in this case, a high cutting accuracy is required for the device, and the movement of the rubber sheet needs to be manually controlled. Utility Model Content

[0004] In view of the problems raised by the above background technology, the purpose of the utility model is to provide a rubber sheet cutting device.

[0005] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0024] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0025] like Figure 1-2 As shown, a rubber sheet cutting device comprises a conveying mechanism 2, a translation mechanism 11 is installed on one side of the top of the conveying mechanism 2, a moving seat 103 is connected to the power output end of the translation mechanism 11, a cylinder 102 is assembled and connected below the moving seat 103, a cutting knife 101 is assembled and connected to the power output end of the cylinder 102, a cutting table 3 is installed below the cutting knife 101 of the conveying mechanism 2, and a limit assembly 4 is provided above the cutting table 3;

[0026] The limiting assembly 4 includes a positioning member 401 and a positioning plate 402. The positioning member 401 is fixedly connected to the cutting knife 101. When the cutting knife 101 is working, the positioning member 401 is slidably connected to the positioning plate 402. A cutting groove 403 is provided in the middle of the positioning plate 402. Two springs 404 are assembled and connected between the positioning plate 402 and the cutting table 3. The two springs 404 are located at both ends of the positioning plate 402 and the cutting table 3. Telescopic rods are provided in the two springs 404.

[0027] According to the technical solution of this embodiment, when cutting the rubber sheet, the end of the rubber sheet is first moved to one side of the cutting table 3, and then the conveying mechanism 2 is started. After the position of the rubber sheet to be cut is moved to below the cutting knife 101, the conveying mechanism 2 stops, and then the cutting knife 101 is controlled by the cylinder 102 and the translation mechanism 11 to cut the rubber sheet. The rubber sheet is located above the cutting table, and then the conveying mechanism is continued to be controlled to transport the rubber sheet, and the cutting position of the rubber sheet is moved to below the cutting knife, and then the next cutting is performed; the limit assembly 4 is used to limit the cutting device when cutting, The rubber sheet is fixed, and the positioning member 401 is used to fix the rubber sheet only when the cutting knife 101 is working. The positioning member 401 cooperates with the limiting component 4 to fix the rubber sheet. When the cutting knife 101 cuts the rubber sheet, the cutting knife 101 drives the positioning member 401 to move downward, and the positioning member 401 presses the positioning plate 402 downward, the spring 404 contracts, and the positioning plate 402 fixes the rubber sheet. The telescopic rod is used to limit the height of the positioning plate 402 to fall. The width of the cutting groove 403 is greater than the width of the rubber sheet. The cutting knife 101 can complete the cutting of the rubber sheet when it moves back and forth.

[0028] The translation mechanism 11 includes a reciprocating screw 111, which is spirally connected to the moving seat 103. Connecting blocks 114 are assembled and connected at both ends of the reciprocating screw 111. Fixed rods 115 are fixedly connected to the lower sides of the two connecting blocks 114. The fixed rods 115 are fixedly connected to the conveying mechanism 2. A motor 112 is assembled and connected to one side of the connecting block 114. The output shaft of the motor 112 is transmission-connected to the reciprocating screw 111. A limiting plate 113 is fixedly connected to the top of the connecting block 114, and the moving seat 103 is slidably connected to the limiting plate 113.

[0029] In this embodiment, the motor 112 drives the reciprocating screw 111 to rotate. When the reciprocating screw 111 rotates, it drives the moving seat 103 to move, so that the moving seat 103 drives the cutting knife 101 to cut the rubber sheet.

[0030] The conveying mechanism 2 includes a support frame 203 , and both ends of the support frame 203 are assembled and connected with electric rollers 201 , and the two electric rollers 201 are drivingly connected with a conveyor belt 202 .

[0031] In this embodiment, the conveying speeds of the two motorized rollers 201 are consistent, and the motorized rollers 201 can be controlled to start and stop at any time. When the motorized rollers 201 are controlled to rotate, the conveyor belt 202 conveys the rubber sheet.

[0032] The cutting table 3 is fixedly connected to the support frame 203 , and the cutting table 3 is located above the conveyor belt 202 .

[0033] The positioning member 401 is a U-shaped frame, and the cutting blade 101 is located in the middle of the U-shaped frame.

[0034] In this embodiment, the distance between the two sides of the U-shaped frame and the cutting knife 101 remains unchanged. When the cutting knife 101 cuts the rubber sheet, the U-shaped frame descends and contacts the positioning plate 402. When the positioning plate 402 cannot descend, the U-shaped frame cannot continue to descend and can only descend to a fixed height.

[0035] The cross section of the cutting table 3 is trapezoidal, and a square groove 301 is provided in the middle of the cutting table 3 . The square groove 301 and the cutting groove 403 have the same shape and size.

[0036] In this embodiment, both sides of the cutting table 3 are inclined surfaces, which can reduce the friction force on the rubber sheet when it moves above the cutting table 3, making it easier for the conveyor belt 202 to drive the rubber sheet to move. The square groove 301 is used to allow the cutting knife 101 to cut through the rubber sheet without contacting the cutting table 3.

[0037] Working principle: When cutting the rubber sheet, first move the end of the rubber sheet to one side of the cutting table 3, then control the electric roller 201 to drive the conveyor belt 202 to transport the rubber sheet, and when the cutting position of the rubber sheet moves to below the cutting knife 101, then start the motor 112 to drive the reciprocating screw 111 and the cylinder 102 to control the cutting knife 101 to cut the rubber sheet. The stroke of the reciprocating screw 111 is equal to the width of the cutting groove 403, so when the motor 112 is working, the cutting knife 101 will only move in the cutting groove 403 to cut the rubber sheet. To perform cutting, the cylinder 102 controls the cutting knife 101 to move downward. When the two sides of the U-shaped frame fixedly connected to the cutting knife 101 contact the positioning plate 402, the U-shaped frame drives the positioning plate 402 to move downward, and the positioning plate 402 compresses the spring 404. When the spring 404 is no longer compressed, the cylinder 102 no longer moves downward, and the cutting knife 101 cuts the rubber sheet. The setting of the square groove 301 of the cutting table 3 enables the cutting knife 101 to completely cut the rubber sheet, but does not contact the surface of the cutting table 3, thereby reducing the wear of the cutting knife 101.

[0038] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
