DETAILED DESCRIPTION

[0018] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1-Figure 8 A cutting device for processing sports rubber products shown in the figure comprises a base 1, a mounting frame 101 is arranged on the top of the base 1, a groove 102 located below the mounting frame 101 is opened on the top of the base 1, a cutting mechanism 2 is arranged on the surface of the mounting frame 101, and a limiting structure 3 is arranged on the surface of the base 1; the cutting mechanism 2 comprises a mounting plate 202 arranged on the inner side of the mounting frame 101, a hydraulic push rod 201 is arranged on the top of the mounting frame 101, the output shaft of the hydraulic push rod 201 passes through the mounting frame 101 and is fixedly connected to the top of the mounting plate 202, a cutting knife 203 corresponding to the groove 102 is arranged on the bottom of the mounting plate 202, an auxiliary component 21 is arranged between the cutting knife 203 and the mounting plate 202, and a positioning component 22 is arranged on the surface of the mounting plate 202; wherein, the auxiliary component 21 comprises a mounting block 215 fixedly connected to the bottom of the mounting plate 202, the bottom of the mounting block 215 is fixedly connected to the top of the cutting knife 203, and the width of the mounting block 215 is smaller than the width of the cutting knife 203.

[0020] By starting the hydraulic push rod 201, the mounting plate 202 can be driven to move downward. During this process, the mounting block 215 drives the cutting knife 203 to move downward to cut the rubber placed on the base 1, so as to facilitate subsequent processing and production of the required sporting goods.

[0021] like Figure 1-Figure 8As shown, a connection box 211 is fixedly connected to the top of the mounting plate 202, an extrusion plate 214 is slidably connected to the inner wall of the connection box 211, a first spring 212 is fixedly connected between the top of the extrusion plate 214 and the inner wall of the connection box 211, an adjustment cavity is formed between the top of the extrusion plate 214 and the inner wall of the connection box 211, an air inlet hole 213 connected to the adjustment cavity is provided on the surface of the connection box 211, and a second one-way valve is provided inside the air inlet hole 213.

[0022] The mounting block 215 has evenly distributed connecting channels 218 formed inside, and both sides of the mounting block 215 have exhaust holes 219 connected to adjacent connecting channels 218 formed therein, and a first one-way valve 217 is disposed inside the connecting channel 218 .

[0023] Two symmetrically distributed baffles 216 are fixedly connected to the bottom of the extrusion plate 214 , and the lower ends of the baffles 216 penetrate the connection box 211 and the mounting plate 202 in sequence and shield the mounting block 215 .

[0024] The inner wall of the connection box 211 is fixedly connected with uniformly distributed conduits 2110 . The upper ends of the conduits 2110 penetrate the extrusion plate 214 and communicate with the adjustment cavity, and the lower ends of the conduits 2110 are communicated with the adjacent connection channel 218 .

[0025] The first one-way valve 217 and the second one-way valve are both relatively mature components in the application of existing technology and will not be elaborated on here. The first one-way valve 217 allows the gas to pass through the connecting channel 218 in one direction and be discharged through the exhaust hole 219, and the second one-way valve allows the external air to enter the interior of the regulating chamber in one direction through the air inlet hole 213.

[0026] In the process of driving the cutting knife 203 to move downward, the cutting knife 203 can gradually pass through the rubber after cutting the rubber. At this time, the bottom of the baffle 216 is blocked by the rubber so that it cannot continue to move downward, and the cutting knife 203 continues to move toward the inside of the groove 102, so that the baffle 216 gradually shrinks to the inside of the connecting box 211. In this process, the squeezing plate 214 can be driven to move upward and compress the air stored in the regulating chamber, so that the internal air can be introduced into the inside of the connecting channel 218 through the conduit 2110, and discharged through the exhaust hole 219, so as to perform jetting at the cutting position to reduce the heat during the cutting process causing the rubber to adhere to the surface of the cutting knife 203 or the cutting knife 203 and the rubber to adhere again after the rubber is separated, affecting the separation. When the cutting knife 203 is reset, the squeezing plate 214 can be driven to reset under the action of the first spring 212. At this time, the internal space of the regulating chamber is restored, and the air pressure is lower than the external air pressure due to the discharge of the internal air. Under the action of the air pressure difference, the external air is stored in the regulating chamber through the air inlet hole 213 and the second one-way valve for reuse.

[0027] like Figure 1-Figure 8 As shown, the positioning assembly 22 includes two connecting plates 221 fixedly connected to both sides of the mounting plate 202 and symmetrically distributed, a pressure frame 224 is provided at the bottom of the mounting plate 202, and the top of the pressure frame 224 is fixedly connected with evenly distributed connecting rods 222, and the upper ends of the connecting rods 222 pass through the adjacent mounting plates 202 and are provided with expanded portions.

[0028] A second spring 223 is sleeved on the surface of the connecting rod 222, the upper end of the second spring 223 is fixedly connected to the bottom of the connecting plate 221, and the lower end of the second spring 223 is fixedly connected to the top of the pressing frame 224; During the cutting process, the pressure frame 224 can contact the rubber before the cutting knife 203, so that when the mounting plate 202 continues to move downward, the pressure frame 224 can be blocked by the rubber and drive the connecting rod 222 to pass through the connecting plate 221 and compress the second spring 223 to strengthen the limitation around the rubber cutting point, improve the positioning effect, and avoid the situation where the traditional positioning point is far away from the cutting point and the cutting position is offset due to the rubber's own deformation ability.

[0029] like Figure 1-Figure 8 As shown, the limiting structure 3 includes a guide rod 301 fixedly connected to one side of the base 1, and a bidirectional screw rod 302 symmetrically distributed with the guide rod 301 is arranged on the other side of the base 1. A limiting plate 306 is arranged on the top of the base 1, and two guide columns 305 symmetrically distributed are arranged on the surface of the limiting plate 306. The lower end of the guide column 305 passes through the limiting plate 306 and is fixedly connected with a mounting seat 303. The mounting seat 303 on one side is threadedly connected to the surface of the bidirectional screw rod 302, and the mounting seat 303 on the other side is slidably connected to the surface of the guide rod 301.

[0030] A third spring 304 is sleeved on the surface of the guide column 305, one end of the third spring 304 is fixedly connected to the surface of the mounting seat 303, and the other end of the third spring 304 is fixedly connected to the bottom of the limiting plate 306; By rotating the bidirectional screw rod 302, the positions of the two limit plates 306 can be adjusted under the action of the mounting seat 303 and the guide rod 301, so as to adapt to rubbers of different sizes, so as to facilitate preliminary clamping by the limit plates 306, thereby improving the application range of the device. The third spring 304 in the accompanying drawings is in a stretched state. Under normal circumstances, the third spring 304 drives the limit plates 306 to be close to the surface of the base 1, so as to achieve the effect of using the limit plates 306 to limit the rubber placed on the surface of the base 1.

[0031] Working principle: The limiting structure 3 is used to achieve the effect of preliminary limiting the rubber placed on the surface of the base 1. By starting the hydraulic push rod 201, the mounting plate 202 can be driven to move downward. During this process, the mounting block 215 drives the cutting knife 203 to move downward to achieve cutting of the rubber placed on the top of the base 1, so as to facilitate subsequent processing and production of the required sporting goods. During the cutting process, the cutting knife 203 can gradually penetrate the rubber after cutting the rubber. At this time, the bottom of the baffle 216 is blocked by the rubber so that it cannot continue to move downward, and the cutting knife 203 continues to move toward the inside of the groove 102, so that the baffle 216 gradually shrinks to the inside of the connecting box 211, and in this process, it can drive the extrusion plate 214 to move upward and compress The air stored in the regulating chamber allows the internal air to be introduced into the interior of the connecting channel 218 through the conduit 2110 and discharged through the exhaust hole 219, thereby jetting air to the cutting position to reduce the heat during the cutting process that causes the rubber to adhere to the surface of the cutting knife 203 or the cutting knife 203 to re-adhere to the rubber after separation from the rubber, affecting the separation. When the cutting knife 203 is reset, the extrusion plate 214 can be driven to reset under the action of the first spring 212. At this time, the internal space of the regulating chamber is restored, and the air pressure is lower than the external air pressure due to the discharge of the internal air. Under the action of the air pressure difference, the external air is stored in the regulating chamber through the air inlet hole 213 and the second one-way valve for reuse.
