[0046] The utility model will be described below with specific embodiments, but it is not limited to the utility model.

[0047] Example one

[0048] As Figures 1-3As shown, in this embodiment, the rubber cutting and slicing device provided includes a rack 1, a support 101 is fixed to the upper middle part of the rack 1; a cutting table 4 is arranged directly below the support 101, and a cutter groove 401 is formed in the side wall of the cutting table 4; wherein, a cutting assembly 5 is arranged on the support 101, the cutting assembly 5 includes a lower pressing block 501 and an upper pressing block 502, the lower pressing block 501 is slidingly connected to the support 101 and used for pressing the rubber sheet during cutting; the upper pressing block 502 is arranged above the lower pressing block 501, a first spring 503 is arranged between the upper pressing block 502 and the lower pressing block 501, the upper end of the first spring 503 is connected to the side wall of the upper pressing block 502, and the lower end of the first spring 503 is connected to the side wall of the lower pressing block 501; a cutter seat 504 is arranged on the upper pressing block 502; a cutter blade 505 is mounted at the lower end of the cutter seat 504; an oil cylinder 506 is fixedly installed on the support 101, and the output shaft of the oil cylinder 506 is connected to the side wall of the upper pressing block 502.

[0049] Wherein, a through groove 5011 is formed in the lower pressing block 501, and the lower end of the cutter blade 505 can penetrate the through groove 5011 and cut the rubber on the cutting table 4.

[0050] An input assembly 2 and an output assembly 3 are arranged on the rack 1, and the input assembly 2 and the output assembly 3 are respectively located on the two sides of the cutting table 4; the input assembly 2 includes a conveying belt 201, the conveying belt 201 is rotationally connected to the rack 1 through two supporting rollers 202, and a motor for driving one supporting roller 202 to rotate is arranged on the rack 1; the structure of the output assembly 3 is the same as that of the input assembly 2.

[0051] A plurality of guide rods 10 are slidingly connected to the support 101, and the lower pressing block 501 and the upper pressing block 502 are slidingly sleeved on the guide rods 10.

[0052] The cutter blade 505 is fixedly installed at the lower end of the cutter seat 504 through a plurality of bolts.

[0053] The process of cutting rubber is as follows:

[0054] The rubber sheet is conveyed to the cutting table 4 via the conveyor belt 201 of the input component 2. The hydraulic cylinder 506 is activated, and its output shaft pushes the upper pressure block 502 and the blade 505 downwards. The upper pressure block 502 is connected to the lower pressure block 501 via the first spring 503, causing the lower pressure block 501 to also move downwards. Once the lower pressure block 501 has pressed the rubber sheet firmly onto the cutting table 4, the output shaft of the hydraulic cylinder 506 continues to push the upper pressure block 502 and the blade 505 downwards, gradually compressing the first spring 503. At this time, the lower pressure block 501 gradually presses the rubber sheet firmly onto the cutting table 4. Simultaneously, the lower end of the blade 505 slides downwards within the through groove 5011 of the lower pressure block 501. After the lower end of the blade 505 passes through the through groove 5011, the blade 505 cuts the rubber sheet on the cutting table 4. After cutting, the hydraulic cylinder 506 retracts and resets, and the cut rubber sheet is output via the output component 3.

[0055] Example 2

[0056] like Figure 2 As shown, based on Embodiment 1, in order to stably transport the rubber sheet to the cutting table 4, a feeding assembly 11 is provided between the cutting table 4 and the input assembly 2. The feeding assembly 11 includes a lower wheel 1101, a pressing frame 1102 and an upper wheel 1103. The lower wheel 1101 is rotatably connected to the frame 1; the pressing frame 1102 is provided on the frame 1 and located above the lower wheel 1101; the upper wheel 1103 is rotatably connected to the pressing frame 1102; wherein, a gap for transporting rubber is provided between the lower wheel 1101 and the upper wheel 1103.

[0057] Multiple connecting rods 12 are fixed on the frame 1. The pressing frame 1102 is slidably sleeved on the connecting rods 12, so that the pressing frame 1102 can move stably in the vertical direction without deviation or tilting. A third spring 13 is provided on the connecting rod 12 for pressing the pressing frame 1102 downward. The function of the third spring 13 is to provide a continuous downward elastic force for the pressing frame 1102, thereby ensuring that the upper wheel 1103 can always be in close contact with the rubber sheet, reducing the shaking and deviation of the rubber sheet during the conveying process.

[0058] Example 3

[0059] like Figure 1 and Figure 3 As shown, based on the above embodiment, in order to further improve the efficiency of the blade 505 in cutting rubber, the blade holder 504 is slidably connected to the upper pressure block 502 by the second spring 6, an inclined block 7 is provided on one side of the blade holder 504, and a pressure roller 9 is rotatably connected to the side wall of the lower pressure block 501 by the support platform 8.

[0060] When the upper pressure block 502 slides downward relative to the lower pressure block 501, the pressure roller 9 slides to one side of the knife holder 504 through the tilting block 7.

[0061] The slope of the inclined block 7 enables the generation of a pushing force to one side when the pressure wheel 9 is in contact with it, thereby guiding the slide of the knife seat 504 and the blade 505 accordingly. The side wall of the lower pressing block 501 is rotatably connected with the pressure wheel 9 through the support 8. During the cutting process, it can effectively contact the inclined block 7 and generate the expected pushing force.

[0062] The cooperation: when the cutting action starts, the upper pressing block 502 drives the knife seat 504 and the blade 505 to slide downward. At this time, the pressure wheel 9 is in contact with the slope of the inclined block 7, and gradually generates a pushing force to one side as the knife seat 504 slides downward. This pushing force not only makes the knife seat 504 slide along the upper pressing block 502, but also makes the blade 505 have a sliding action to one side while cutting the rubber. It helps to reduce the resistance and friction during the cutting process, so that the blade 505 can cut the rubber sheet more smoothly, thereby improving the cutting efficiency.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate and not to limit the technical solutions of the present application. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present application can still be modified or replaced by the equivalent, without departing from the spirit and scope of the present application. Any modification or partial replacement should be covered in the scope of the claims of the present application.
