Description

Technical Field

[0001] The present invention relates to the technical field of insole cutting devices, and specifically relates to a foamed insole cutting device. Background Art

[0002] ‌A foamed insole is an insole made of foamed material, which has good cushioning, shock absorption and support performance, and can provide a comfortable shoe-wearing experience. The foamed insole is usually made of foamed polyester or foamed polyurethane, has high toughness and elasticity, and can be customized according to different sole shapes and thicknesses. During the production of foamed insoles, rectangular materials need to be cut to obtain the shape of the insole.

[0003] However, in a traditional cutting device, after a piece of material is placed, it will enter the inside of the cutting machine for cutting. After cutting, the fabric will move out from the inside of the cutting machine, and then the staff manually separates the cut insoles and waste materials. Only after the separation is completed can the next piece of material be placed and the cutting work of the next piece of material be carried out. This process is time-consuming and not convenient for rapid cutting, resulting in low cutting efficiency. Moreover, when the cutting die contacts the material instantaneously during the cutting process, a certain impact force will be generated, which will not only produce a large amount of noise, but also the cutting die under a large impact force is prone to damage. In addition, the tabletop of a general cutting device is small and cannot temporarily store the material before cutting and the insoles after cutting, thus being inconvenient to use.

Four synchronous pulleys 301 are fixedly connected to one side inside the connecting frame 2, and four synchronous pulleys 301 are also fixedly connected to the other side inside the connecting frame 2. The same synchronous belt 302 is wound around the four synchronous pulleys 301 on the same side of the connecting frame 2. A first connecting plate 303 is fixedly connected to the synchronous belt 302. The tops of the two first connecting plates 303 are fixedly connected to the same first joint plate 304. A second connecting plate 305 is fixedly connected to the synchronous belt 302. The tops of the two second connecting plates 305 are fixedly connected to the same second joint plate 306. Two sliding plates 307 are slidably connected to the second joint plate 306. The tops of the two sliding plates 307 are fixedly connected to the same third joint plate 308. A guide shaft 309 is fixedly connected to the bottom end of the sliding plate 307. Two vertical plates 311 are fixedly connected to the inside of the connecting frame 2. The bottom end of the second joint plate 306 is slidably connected to the tops of the two vertical plates 311. A guide groove 310 is provided on the vertical plate 311. The guide shaft 309 extends into the adjacent guide groove 310 and is slidably connected to the vertical plate 311. Two motors 312 are respectively installed on both sides outside the connecting frame 2. The output shaft of the motor 312 is fixedly connected to the adjacent synchronous pulley 301. The top surfaces of the first joint plate 304 and the third joint plate 308 are on the same plane. The overall cross-section of the first connecting plate 303 is in an L-shaped structure. The overall cross-section of the second connecting plate 305 is in an L-shaped structure. The positioning structure 6 includes a support plate 601 and a first guide post 602. Two support plates 601 are respectively fixedly connected to both sides of the material loading plate 5. Two first guide posts 602 are slidably connected to the support plate 601. One end of the adjacent two first guide posts 602 is fixedly connected to the same baffle 603. A first screw 605 is threadedly connected to the support plate 601. One end of the first screw 605 is fixedly connected to a driving knob 604. The other end of the first screw 605 is rotatably connected to the baffle 603. A retaining piece 606 is slidably connected to the baffle 603. A second screw 607 is fixedly connected to the retaining piece 606. A fixing knob 608 is threadedly connected to the second screw 607. One side of the fixing knob 608 abuts against the baffle 603. The overall cross-section of the support plate 601 is in an L-shaped structure. The overall cross-section of the retaining piece 606 is in an L-shaped structure. That is, the material to be cut can be placed through the material loading plate 5. During the process of placing the material, it can be resisted by the two baffles 603 and the two retaining pieces 606, so as to facilitate the positioning of the material, ensure that the material is in the same position on the material loading plate 5 every time after being placed, thus facilitating subsequent cutting. And by holding the driving knob 604 and rotating the first screw 605, the rotation of the first screw 605 will drive the baffle 603 to move,By providing two first guide posts 602, the baffle 603 can be guided for movement, and the fixed knob 608 can be rotated at the same time. When one side of the fixed knob 608 is not tightly against the baffle 603, the baffle 606 can be moved to change its position on the baffle 603. By adjusting the positions of the two baffles 603 and the two baffles 606, materials of different sizes can be positioned, thereby effectively improving the flexibility of use. During the cutting process, when the material on one of the carrier plates 5 moves to the bottom end of the cutting die 805, the other material that has not been cut can be placed on the other carrier plate 5, and the other carrier plate 5 can be placed The tray 403 is placed on the carrier plate 5, and the placement groove 404 is provided to play a positioning role for the material carrier plate 5. When the material on one of the material carrier plates 5 is cut, the two motors 312 can be started at the same time. The output shaft of the motor 312 rotates to drive the adjacent synchronous wheel 301 to rotate. The rotation of the two synchronous wheels 301 will respectively make the two synchronous belts 302 move synchronously. The movement of the synchronous belt 302 will drive the second connecting plate 305 to move away from the cutting die 805, and at the same time drive the first connecting plate 303 to move toward the cutting die 805. The movement of the two first connecting plates 303 will drive the first connecting plate 304 to move, and the movement of the first connecting plate 304 will drive the other The other material carrier plate 5 at the top moves toward the bottom end of the cutting die 805, and the movement of the two second connecting plates 305 will drive the second connecting plate 306 to move, and the movement of the second connecting plate 306 will drive the two slide plates 307 to move, and the two slide plates 307 will drive the third connecting plate 308 to move, and the third connecting plate 308 drives one of the material carrier plates 5 at its top to move away from the cutting die 805. When the slide plate 307 moves, the guide shaft 309 at the bottom end of the slide plate 307 will move inside the guide groove 310. When the guide shaft 309 moves at the inclined position of the guide groove 310, the slide plate 307 will slide on the second connecting plate 306, so that one of the material carrier plates 5 can be moved. The material plate 5 and the other material carrier plate 5 are staggered during the relative movement to avoid collision. When the positions of the two material carrier plates 5 are swapped, the output shafts of the two motors 312 stop rotating at the same time. Then the staff can remove one of the material carrier plates 5 from the tray 403 and repeat the above operation. Since the other material carrier plate 5 can move to the bottom of the cutting die 805 while one of the material carrier plates 5 moves out from the bottom of the cutting die 805, the waiting time can be effectively shortened, and the cut insole and waste can be separated during cutting, thereby effectively shortening the cutting time and improving the cutting efficiency.

[0023] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7As shown, the buffer structure 4 includes connecting columns 401 and buffer springs 402. Four connecting columns 401 are fixedly connected to the first connecting plate 304, and four connecting columns 401 are also fixedly connected to the third connecting plate 308. Buffer springs 402 are sleeved outside the connecting columns 401. The same tray 403 is slidably connected to four adjacent connecting columns 401. A placement groove 404 is provided on the tray 403. The material loading plate 5 is engaged with the placement groove 404. One end of the four buffer springs 402 at the top of the first connecting plate 304 abuts against one of the material loading plates 5 and the other end abuts against the first connecting plate 304. One end of the four buffer springs 402 at the top of the third connecting plate 308 abuts against the other material loading plate 5 and the other end abuts against the third connecting plate 308. The overall cross-section of the connecting column 401 is in a T-shaped structure. The cutting structure 8 includes a support base 801 and a hydraulic cylinder 802. The support base 801 is fixedly connected to the top of the machine base 1. The hydraulic cylinder 802 is installed on the top of the support base 801. The bottom end of the hydraulic cylinder 802 is fixedly connected to a mounting seat 803. A cutting die 805 is installed at the bottom end of the mounting seat 803. Four second guide columns 804 are fixedly connected to the top of the mounting seat 803. The second guide columns 804 are slidably connected to the support base 801. The cutting die 805 is located directly above the third connecting plate 308. That is, when the material is at the bottom of the cutting die 805, the hydraulic cylinder 802 can be started. When the hydraulic cylinder 802 extends, it will drive the mounting seat 803 to move. By setting the four second guide columns 804, the mounting seat 803 can be guided in its movement, thus ensuring the stability of the movement of the mounting seat 803. The movement of the mounting seat 803 will drive the cutting die 805 to move towards the material. During the process of the cutting die 805 contacting the material, the tray 403 will slide on the four connecting columns 401, and the four buffer springs 402 will contract simultaneously. Therefore, it can play a buffering role, reducing noise and also reducing the probability of damage to the cutting die 805, thus being more convenient to use.

[0024] Specifically, as Figure 1 and Figure 2As shown, the placement structure 7 includes a storage board 701 and a first connecting block 702. Two storage boards 701 are provided on both sides of the machine base 1. Two first connecting blocks 702 are fixedly connected to the bottom end of the storage board 701. The first connecting block 702 is rotatably connected to the second connecting block 703, and the second connecting block 703 is fixedly connected to the machine base 1. Two third connecting blocks 704 are fixedly connected to the bottom end of the storage board 701. The same connecting shaft 705 is rotatably connected between the two third connecting blocks 704. Two support rods 706 are fixedly connected to the connecting shaft 705. Two grooves 707 are provided on both sides of the machine base 1. The end of the support rod 706 is located inside the groove 707 and abuts against the machine base 1. The top surface of the storage board 701 is flush with the top surface of the machine base 1. The support rod 706 is perpendicular to the connecting shaft 705, that is: the uncut materials and the insole after cutting can be temporarily stored by the two storage boards 701, so it is more convenient to use. And when the cutting device is not needed, the support rod 706 can be rotated. Since the two support rods 706 are fixedly connected to the same connecting shaft 705, when one of the support rods 706 is rotated, the other support rod 706 also rotates accordingly. When the ends of the two support rods 706 are disengaged from the inside of the groove 707, the storage board 701 can be rotated towards the machine base 1. Therefore, when the cutting device is not used, the two storage boards 701 can be folded and stored on both sides of the machine base 1, so as to reduce the space occupation and improve the space utilization efficiency.

[0025] When the present invention is in use, the material to be cut can be placed on the material carrier plate 5. In the process of placing the material, the two baffles 603 and the two baffles 606 can be used to block the material, so as to facilitate the positioning of the material and ensure that the material is in the same position of the material carrier plate 5 each time after placement, so as to facilitate subsequent cutting. The first screw rod 605 is rotated by hand-held driving knob 604, and the rotation of the first screw rod 605 will drive the baffle plate 603 to move. The two first guide columns 602 can guide the baffle plate 603. At the same time, the fixing knob 608 can be rotated. When one side of the fixing knob 608 is not tightly against the baffle plate 603, the baffle plate 606 can be moved to change its position on the baffle plate 603. The positions of the two baffles 603 and the two baffles 606 can be adjusted to position materials of different sizes, thereby effectively improving the flexibility of use. During the cutting process, when the material on one of the carrier plates 5 moves to the bottom end of the cutting die 805, the other uncut material can be placed on the other carrier plate 5, and the other carrier plate 5 can be placed on the tray 403. By setting the placement groove 404, the carrier plate 5 can be positioned. When the cutting of the material on one of the carrier plates 5 is completed, the two motors 312 can be started at the same time. The output shaft of the motor 312 rotates to drive the adjacent synchronous wheel 301 to rotate. The rotation of the two synchronous wheels 301 will respectively cause the two synchronous belts 302 to move synchronously, and the movement of the synchronous belt 302 will The second connecting plate 305 is driven to move away from the cutting die 805, and the first connecting plate 303 is driven to move toward the cutting die 805. The movement of the two first connecting plates 303 will drive the first connecting plate 304 to move. The movement of the first connecting plate 304 will drive another material carrying plate 5 at its top to move toward the bottom end of the cutting die 805. The movement of the two second connecting plates 305 will drive the second connecting plate 306 to move. The movement of the second connecting plate 306 will drive the two slide plates 307 to move. The two slide plates 307 will drive the third connecting plate 308 to move. The third connecting plate 308 drives one of the material carrying plates 5 at its top to move away from the cutting die 805. When the slide plate 307 moves, the guide shaft 309 at the bottom thereof will be inside the guide groove 310. When the guide shaft 309 moves at the inclined position of the guide groove 310, the slide plate 307 will slide on the second connecting plate 306, so that one of the material carriers 5 and the other material carrier 5 can be staggered during the relative movement to avoid collision. When the positions of the two material carriers 5 are swapped, the output shafts of the two motors 312 stop rotating at the same time, and then the staff can remove one of the material carriers 5 from the tray 403 and then repeat the above operation. Since the other material carrier 5 can be moved to the bottom end of the cutting die 805 while one of the material carriers 5 moves out from the bottom end of the cutting die 805, the waiting time can be effectively shortened, and the cut insole and waste can be separated during cutting.Thereby effectively shortening the cutting time and improving the cutting efficiency; When the material is at the bottom of the cutting die 805, the hydraulic cylinder 802 can be started, and the extension of the hydraulic cylinder 802 will drive the mounting seat 803 to move. The four second guide pillars 804 can guide the mounting seat 803, thereby ensuring the stability of the movement of the mounting seat 803. The movement of the mounting seat 803 will drive the cutting die 805 to move toward the material. During the contact between the cutting die 805 and the material, the tray 403 will slide on the four connecting pillars 401, and the four buffer springs 402 will shrink at the same time, so as to play a buffering role, reduce noise and also reduce the probability of damage to the cutting die 805, so that it is more convenient to use. The two storage plates 701 can be used to temporarily store uncut materials and insoles after cutting, making it more convenient to use. When the cutting device is not needed, the support rod 706 can be rotated. Since the two support rods 706 are fixedly connected to the same connecting shaft 705, when one of the support rods 706 is rotated, the other support rod 706 also rotates accordingly. When the ends of the two support rods 706 are disengaged from the inside of the groove 707, the storage plate 701 can be rotated toward the base 1. Therefore, when the cutting device is not in use, the two storage plates 701 can be folded and stored on both sides of the base 1, thereby reducing space occupancy and improving space utilization efficiency.
