Description

Technical Field

[0001] The present invention relates to the technical field of sponge cutting, in particular to a foaming sponge cutting device and a cutting method thereof. Background Art

[0002] Foam sponge is a porous, lightweight material with thermal insulation, sound insulation, sound absorption, and shock absorption properties. It is widely used in construction, refrigeration, transportation, water rescue, and various packaging applications. The production process of foam sponge significantly impacts its performance. Typical production processes require cutting the sponge to the appropriate size and dimensions. Using a sponge cutting device instead of traditional manual cutting can significantly save time and labor costs. This device is not only suitable for large-scale cutting tasks in industrial production, but can also be used for small-batch, customized, and diversified products, improving production efficiency and quality.

[0003] Existing sponge cutting devices usually adopt an assembly line type, which cuts the sponge during transportation through a combination of a conveyor belt and a cutting machine. However, this cutting method is prone to produce burrs, and if the sponge is subjected to uneven force during transportation, the cutting knife may also be offset during cutting, resulting in deviations in the size and shape of the sponge. Therefore, staff are required to additionally check the cross-section of the sponge after cutting to prevent burrs and size deviations from affecting the product effect. Such additional trimming of the sponge will result in a waste of manpower and time costs. Summary of the Invention

[0010] As a preferred solution of the foam sponge cutting device described in the present invention, the scraping mechanism includes: a second motor, a roller assembly installed on the output end of the second motor, a first gear rotatably connected to one side of the roller assembly and a second gear on the other side, a first rack meshed on the surface of the first gear and a second rack meshed on the surface of the second gear, and the first rack is fixed on one side of the cutting platform; the scraping mechanism includes: a third rack fixedly installed on one side of the cutting platform, a third gear meshed on the surface of the third rack, a fourth gear rotatably connected to one side of the third gear, a fourth rack meshed on the surface of the fourth gear and a blanking plate fixedly connected to the fourth rack.

[0013] As a preferred solution of the foam sponge cutting device of the present invention, one side of the second rack is fixedly connected to the push plate, and the push plate is slidably connected in the collecting chamber.

[0014] The cutting method of the foam sponge cutting device as described above comprises the following steps: Step 1: placing the sponge body to be cut on a conveyor belt, conveying it forward through a conveying unit, and starting a hydraulic rod to drive the blade downward after reaching a fixed frame to preliminarily cut the sponge into squares. The cut square sponge is conveyed to an operating table, and the electric push rod is started to move the positioning unit upward, and then the second motor is started to drive the roller assembly to rotate, so that the first gear and the second gear rotate synchronously. When the first gear rotates, it drives the first rack downward, thereby driving the cutting platform downward. When the second gear rotates, it drives the second rack to move, thereby driving the push plate to move into the collection chamber. Step 2: When the cutting platform moves down, the third rack on the other side moves down, driving the third gear to rotate, and then driving the fourth gear to rotate, so that the fourth rack drives the blanking plate to move outward. At this time, due to the withdrawal and movement of the blanking plate during transmission, the position of the cut square sponge will be offset. When the cutting platform moves down halfway, the positioning unit will be activated to adjust the offset sponge. Step 3: When the cutting platform moves down, press the control button to contract the spring, driving the control rod to move backward. At this time, the rotation of the connecting rod drives the fixed rod to deflect, which in turn drives the turntable to rotate slightly, so that the four adjustment rods rotate and drive the four positioning blocks to move inward. The positioning blocks abut the four sides of the square sponge to position it in the center of the operating table. When the cutting platform continues to move down past the control button, the spring is unloaded and drives it to rebound, causing the four positioning blocks to move outward and no longer abut the sides of the square sponge, making it easier for the cutting unit to remove burrs; Step 4: During cutting, the cutting platform is pressed on the square sponge to fix it, and then the third motor is started to drive the rotating rod to rotate, thereby driving the first bevel gear and the third bevel gear to rotate synchronously. The first bevel gear drives the meshed second bevel gear to rotate, thereby driving the threaded rod and the bevel gear set to rotate, so that the four threaded rods rotate synchronously, thereby driving the cutting blade on the threaded rod to move, so that the cutting blade can simultaneously cut and clean the four side burrs of the square sponge. When the third bevel gear rotates, it can drive the fourth bevel gear to rotate, and through the meshing of the chain, it drives multiple drive gears to rotate synchronously, thereby rotating the two fan blades, generating adsorption force on the cut burrs, so that they fall into the collection chamber; Step 5: After cutting, the second motor rotates in the opposite direction to move the cutting platform up. At this time, the second rack drives the push plate to move in the opposite direction to push the burrs and debris accumulated in the collection chamber out of the discharge port. At the same time, the fourth rack drives the discharge plate to move in the opposite direction to push the cleaned square sponge into the collection box. When the collection box is full, pull it out and replace it with a new collection box so that the first magnetic block and the second magnetic block are adsorbed. The new collection box can be fixed on one side of the cleaning box.

[0015] Beneficial effects of the present invention: The present invention proposes a foam sponge cutting device and a cutting method thereof. The cutting method in this scheme is mainly realized by a foam sponge cutting device composed of a conveying unit, a positioning unit, a control unit and a cutting unit. The sponge is cut into a square by the conveying unit and placed on an operating table.

The entire process is completed through the mechanical coordination of the positioning unit, the control unit and the cutting unit, which is convenient for processing the burrs and bevels of the sponge after cutting, and prevents errors and labor intensity caused by manual operation, reducing waste of manpower and time costs.

[0028] Reference Figures 1 to 7 , is an embodiment of the invention, providing a foam sponge cutting device and a cutting method thereof, the cutting method using a foam sponge cutting device, the device comprising a conveying unit 100, a positioning unit 200, a control unit 300 and a cutting unit 400, the method comprising the following steps: Step 1: Place the sponge body 1041 to be cut on the conveyor belt 104, and convey it forward through the conveying unit 100. After reaching the fixed frame 105, start the hydraulic rod 106 to drive the blade 107 to move downward, and preliminarily cut the sponge into squares. The cut square sponge is conveyed to the operating table 1013, and the electric push rod 201 is started to move the positioning unit 200 upward. Then, the second motor 301 is started to drive the roller assembly 302 to rotate, so that the first gear 303 and the second gear 304 rotate synchronously. When the first gear 303 rotates, it drives the first rack 305 to move downward, and then drives the cutting platform 307 to move downward. When the second gear 304 rotates, it drives the second rack 306 to move, and then drives the push plate 3061 to move into the collection chamber; Step 2: When the cutting platform 307 moves downward, the third rack 308 on the other side moves downward, driving the third gear 309 to rotate, and then driving the fourth gear 310 to rotate, so that the fourth rack 311 drives the blanking plate 312 to move outward. At this time, due to the withdrawal and movement of the blanking plate 312 during transportation, the position of the cut square sponge will be offset. When the cutting platform 307 moves halfway down, the positioning unit 200 will be activated to adjust the offset sponge. Step 3: When the cutting platform 307 moves downward, it presses against the control button 207 to contract the spring 2072, driving the control rod 206 to move backward. At this time, the rotation of the connecting rod 205 drives the fixed rod 204 to deflect, thereby driving the turntable 203 to rotate slightly, so that the four adjusting rods 208 rotate and drive the four aligning blocks 209 to move inward. The aligning blocks 209 abut against the four sides of the square sponge to position it at the center of the operating table 1013. When the cutting platform 307 continues to move downward past the control button 207, the spring 2072 is not forced to rebound, so that the four aligning blocks 209 move outward and no longer abut against the sides of the square sponge, making it easier for the cutting unit 400 to remove the burrs. Step 4: During cutting, the cutting platform 307 is pressed on the square sponge to fix it, and then the third motor 401 is started to drive the rotating rod 402 to rotate, thereby driving the first bevel gear 403 and the third bevel gear 408 to rotate synchronously. The first bevel gear 403 drives the meshed second bevel gear 404 to rotate, thereby driving the threaded rod 405 and the bevel gear set 406 to rotate, so that the four threaded rods 405 rotate synchronously, thereby driving the cutting blade 407 on the threaded rod 405 to move, so that the cutting blade 407 can simultaneously cut and clean the four side burrs of the square sponge. When the third bevel gear 408 rotates, it can drive the fourth bevel gear 409 to rotate, and the engagement of the chain 4092 drives the multiple driving gears 4091 to rotate synchronously, thereby rotating the two fan blades 4093, generating an adsorption force on the cut burrs, so that they fall into the collection chamber; Step 5: After cutting, the second motor 301 rotates in the opposite direction to move the cutting platform 307 upward. At this time, the second rack 306 drives the push plate 3061 to move in the opposite direction to push the burrs and debris accumulated in the collection chamber out of the discharge port. At the same time, the fourth rack 311 drives the discharge plate 312 to move in the opposite direction to push the cleaned square sponge into the collection box 1017. When the collection box 1017 is full, pull it out and replace it with a new collection box 1017 so that the first magnetic block 1015 and the second magnetic block 1016 are adsorbed. The new collection box 1017 can be fixed on one side of the cleaning box 1011.

[0029] The conveying unit 100 includes a conveying frame 101, a first motor 102 installed on one side of the conveying frame 101, a conveying roller 103 and a conveyor belt 104 installed on the output end of the first motor 102, a fixing frame 105 fixedly installed on the conveying frame 101, a hydraulic rod 106 fixedly installed on the fixing frame 105, and a blade 107 detachably connected to the transmission end of the hydraulic rod 106 by a fixing bolt; a cleaning box 1011 is fixedly connected to one side of the conveying frame 101, a collecting chamber is provided in the cleaning box 1011, and a discharge port is provided on one side of the collecting chamber; a conical frame 1012 is fixedly connected to the inner side wall of the collecting chamber, and the conical frame An operating table 1013 is fixedly connected to the top of 1012; a mounting plate 1014 is fixedly connected to the back of the cleaning box 1011, and the third motor 401 is fixedly installed on the mounting plate 1014; a first magnetic block 1015 is fixedly connected to one side of the cleaning box 1011, and a second magnetic block 1016 is adsorbed on the first magnetic block 1015, and the second magnetic block 1016 is fixedly connected to one side of the collection box 1017; a handle 1018 is fixedly connected to the other side of the collection box 1017, and a movable frame 1019 is fixedly connected to the bottom of the collection box 1017; a sponge body 1041 is placed on the conveyor belt 104.

[0030] During use, the sponge body 1041 is transported forward by the conveyor belt 104. During the transportation process, the blade 107 is driven downward by the transmission end of the hydraulic rod 106 to cut the sponge body 1041. When the blade 107 is rusted, it can be replaced by the fixing bolt. The cut burrs and debris can be collected and processed by the cleaning box 1011. The adsorption effect of the first magnetic block 1015 and the second magnetic block 1016 facilitates the connection between the collection box 1017 and the cleaning box 1011.

[0031] The positioning unit 200 includes an electric push rod 201, a lifting frame 202 fixedly mounted on the transmission end of the electric push rod 201, a turntable 203 rotatably connected to the lifting frame 202, a fixed rod 204 fixedly connected to the center of the turntable 203, a connecting rod 205 rotatably connected to one end of the fixed rod 204, a control rod 206 rotatably connected to one end of the connecting rod 205, a control button 207 fixedly connected to the top of the control rod 206, an adjusting rod 208 rotatably connected to the edge of the turntable 203, and a positioning block 209 rotatably connected to one end of the adjusting rod 208; a telescopic rod 2071 is fixedly connected to the back side of the control button 207, a spring 2072 is sleeved on the surface of the telescopic rod 2071, and one side of the spring 2072 is fixedly connected to one side of the lifting frame 202.

[0032] During use, when there is no square sponge on the operating table 1013, the transmission end of the electric push rod 201 contracts and drives the positioning unit 200 to move downward to prevent the positioning block 209 from affecting the transportation of the sponge. When the square sponge has been transported to the operating table 1013, the sponge is centered by moving the cutting platform 307 in coordination with the positioning unit 200, and the telescopic rod 2071 supports the spring 2072 to prevent the spring 2072 from moving downward due to gravity and driving the displacement of the control button 207.

[0033] The control unit 300 includes: a cutting platform 307, a discharge mechanism and a scraping mechanism, and the discharge mechanism, the scraping mechanism and the cutting platform 307 work synchronously. When the cutting platform 307 descends, the discharge mechanism and the scraping mechanism are initialized synchronously. When the cutting platform 307 rises, the discharge mechanism pushes the material and the scraping mechanism scrapes off the burrs under cutting. The scraping mechanism includes: a second motor 301, a roller assembly 302 installed at the output end of the second motor 301, a first gear 303 rotatably connected to one side of the roller assembly 302 and a second gear 304 on the other side, and a first rack 300 meshing with the surface of the first gear 303. 5 and a second rack 306 meshing with the surface of the second gear 304, the first rack 305 is fixed to one side of the cutting platform 307; the scraping mechanism includes: a third rack 308 fixedly mounted on one side of the cutting platform 307, a third gear 309 meshing with the surface of the third rack 308, a fourth gear 310 rotatably connected to one side of the third gear 309, a fourth rack 311 meshing with the surface of the fourth gear 310 and a blanking plate 312 fixedly connected to the fourth rack 311; one side of the second rack 306 is fixedly connected to the push plate 3061, and the push plate 3061 is slidably connected in the collecting chamber.

[0034] During use, the second motor 301 drives the cutting platform 307 to move downward, the push plate 3061 moves to the left, and the blanking plate 312 moves to the left away from the operating table 1013. When the cutting is completed and the cutting platform 307 moves upward, the push plate 3061 moves to the right to push out the burrs, and the blanking plate 312 moves to the right to push the cut square sponge into the collection box 1017.

[0035] The cutting unit 400 includes a third motor 401, a rotating rod 402 installed at the output end of the third motor 401, a first bevel gear 403 rotatably connected to the surface above the rotating rod 402, a second bevel gear 404 meshed with the surface of the first bevel gear 403, a threaded rod 405 rotatably connected to one side of the second bevel gear 404, a bevel gear set 406 rotatably connected to one end of the threaded rod 405, a cutting blade 407 threadedly connected to the surface of the threaded rod 405, a third bevel gear 408 rotatably connected to the surface below the rotating rod 402, and a fourth bevel gear 409 meshed with the surface of the third bevel gear 408; one side of the fourth bevel gear 409 is rotatably connected to a driving gear 4091, the surface of the driving gear 4091 is meshed with a chain 4092, and one side of the driving gear 4091 is rotatably connected to a fan blade 4093.

[0036] During use, the cutting unit 400 is driven by the third motor 401 to operate, so that when the four cutting blades 407 cut the four sides of the square sponge, the fan blades 4093 rotate to generate adsorption force on the cut debris and bevel edges, and suck them into the collection chamber to prevent the debris from flying and making it inconvenient to collect.

[0037] It is worth noting that the entire device is controlled by a controller. Since the controller is a commonly used device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

10. A foam sponge cutting method, using the foam sponge cutting device according to claim 9, characterized in that: The method comprises the following steps: Step 1: placing the sponge body (1041) to be cut on the conveyor belt (104), conveying it forward through the conveying unit (100), and starting the hydraulic rod (106) after reaching the fixed frame (105) to drive the blade (107) to move downward, and preliminarily cutting the sponge into squares. The cut square sponge is conveyed to the operating table (1013), starting the electric push rod (201) to move the positioning unit (200) upward, and then starting the second motor (301) to drive the roller assembly (302) to rotate, so that the first gear (303) and the second gear (304) rotate synchronously, and when the first gear (303) rotates, it drives the first rack (305) to move downward, and then drives the cutting platform (307) to move downward, and when the second gear (304) rotates, it drives the second rack (306) to move, and then drives the push plate (3061) to move into the collection chamber; Step 2: When the cutting platform (307) moves downward, the third rack (308) on the other side moves downward, driving the third gear (309) to rotate, and then driving the fourth gear (310) to rotate, so that the fourth rack (311) drives the blanking plate (312) to move outward. At this time, the position of the cut square sponge will be offset due to the withdrawal and movement of the blanking plate (312) during transmission. When the cutting platform (307) moves down to halfway, the positioning unit (200) will be activated to adjust the offset sponge. Step 3: When the cutting platform (307) moves downward, it presses against the control button (207) to contract the spring (2072), driving the control rod (206) to move backward. At this time, the rotation of the connecting rod (205) drives the fixed rod (204) to deflect, thereby driving the turntable (203) to rotate slightly, so that the four adjustment rods (208) rotate and drive the four positioning blocks (209) to move inward. The positioning blocks (209) abut against the four sides of the square sponge to position it at the center of the operating table (1013). When the cutting platform (307) continues to move downward past the control button (207), the spring (2072) is not subjected to force and drives it to rebound, so that the four positioning blocks (209) move outward and no longer abut against the side edges of the square sponge, making it easier for the cutting unit (400) to cut off the burrs. Step 4: During cutting, the cutting platform (307) is pressed on the square sponge to fix it, and then the third motor (401) is started to drive the rotating rod (402) to rotate, thereby driving the first bevel gear (403) and the third bevel gear (408) to rotate synchronously. The first bevel gear (403) drives the meshed second bevel gear (404) to rotate, thereby driving the threaded rod (405) and the bevel gear set (406) to rotate, so that the four threaded rods (405) rotate synchronously, thereby driving the cutting blade (407) on the threaded rod (405) to move, so that the cutting blade (407) can simultaneously cut and clean the four side burrs of the square sponge. When the third bevel gear (408) rotates, it can drive the fourth bevel gear (409) to rotate, and through the meshing of the chain (4092), it drives the multiple driving gears (4091) to rotate synchronously, thereby causing the two fan blades (4093) to rotate, generating an adsorption force on the cut burrs, so that they fall into the collection chamber; Step 5: After cutting, the second motor (301) rotates in the opposite direction to move the cutting platform (307) upward. At this time, the second rack (306) drives the push plate (3061) to move in the opposite direction to push the burrs and debris accumulated in the collection chamber out of the discharge port. At the same time, the fourth rack (311) drives the discharge plate (312) to move in the opposite direction to push the cleaned square sponge into the collection box (1017). When the collection box (1017) is full, it is pulled out and replaced with a new collection box (1017) so that the first magnetic block (1015) and the second magnetic block (1016) are adsorbed. The new collection box (1017) can then be fixed on one side of the cleaning box (1011).
