Description

Technical Field

[0001] This utility model relates to the field of cutting machine technology, and more specifically, to a foam cutting machine. Background Technology

[0002] A foam cutting machine is a specialized piece of equipment used for cutting foam materials. Foam materials, due to their lightweight, softness, and durability, are widely used in shoe insoles, packaging, sporting goods, and other fields. Through advanced technology and design, foam cutting machines can efficiently and accurately complete the cutting of foam materials, improving production efficiency and product quality.

[0003] Existing foam cutting machines first cut the pattern to be cut, and then remove the cut foam to take out the part that needs to be removed. However, if the area to be removed is too small, it is difficult to remove the waste by hand and it is easy to damage the foam that needs to be used. Therefore, a new solution is needed to solve the problem that the waste to be removed from the foam is too small to be easily removed. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a foam cutting machine, which is equipped with a device to facilitate the removal of excessively small waste parts from the foam.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a foam cutting machine, including a worktable and a cutting device slidably connected thereto. The worktable has several through slots extending through its thickness. A support platform is provided below the worktable, and a sliding rod is slidably connected to the support platform. A top-feeding device is slidably connected inside the sliding rod. A driven rod is provided above the worktable, and a storage box is slidably connected inside the driven rod. The driven rod and the sliding rod are fixedly connected by a connecting rod. The connecting rod has a cavity, and a driving device is rotatably connected inside the cavity, with its two ends fixedly connected to the storage box and the top-feeding device respectively. The rotation angle of the driving device is proportional to the moving distance of the storage box and the top-feeding device. An adjustment groove extending through the width of the connecting rod is provided on the inner wall of the cavity. An adjustment rod fixedly connected to the top-feeding device is slidably connected inside the adjustment groove. When the adjustment rod abuts against the inner top surface of the adjustment groove, the length of the top-feeding device entering the storage box is at its maximum value.

[0006] The present invention is further configured such that: the driving device includes a rotating shaft and a first traction rope and a second traction rope; the rotating shaft is rotatably connected to the inner wall of the cavity; one end of the first traction rope is fixedly connected to the top material device and its other end is fixedly connected to the end of the rotating shaft away from the cutting device; one end of the second traction rope is fixedly connected to the storage box and its other end is fixedly connected to the end of the rotating shaft close to the cutting device.

[0007] The present invention is further configured such that: the feeding device includes a moving block and a feeding pin; the moving block is fixedly connected to one end of the traction rope away from the rotating shaft; two limiting plates with grooves are fixedly connected on both sides of the feeding pin along the width direction of the sliding rod on the moving block; the feeding pin is slidably connected to the inner wall of the groove; and the feeding pin is fixedly connected to one end of the adjusting rod.

[0008] The present invention is further configured such that: the storage box has a feed inlet facing the workbench, a rotating plate that shields the feed inlet is rotatably connected to the inner wall of the feed inlet, and a limiting strip is fixedly connected to the bottom surface of the storage box below the feed inlet.

[0009] The present invention is further configured such that: the top surface of the sliding rod is recessed inward to form a T-shaped sliding groove; the moving block is slidably connected to the inner wall of the sliding groove and the outer peripheral wall of the moving block is in contact with the inner wall of the sliding groove; the inner side wall of the sliding groove away from the connecting rod is recessed inward to form a first receiving groove; an elastic element is fixedly connected to the side of the first receiving groove away from the connecting rod; and the other end of the elastic element is fixedly connected to the moving block.

[0010] The present invention is further configured such that: a T-shaped moving groove is formed by an inward recess on the bottom surface of the driven rod; the storage box is slidably connected to the inner wall of the moving groove by a slider, and the outer peripheral wall of the slider is in contact with the inner wall of the moving groove; a second receiving groove is formed by an inward recess on the inner side wall of the moving groove away from the connecting rod; an elastic element two is fixedly connected to the side of the second receiving groove away from the connecting rod; and the other end of the elastic element two is fixedly connected to the slider.

[0011] The present invention is further configured such that the height of the adjustment groove is greater than the maximum value of the distance between the bottom surface of the storage box and the ejector pin.

[0012] In summary, this utility model has the following beneficial effects: A foam cutting machine first cuts and removes small patterns that need to be removed. The upper and lower sides of the worktable are respectively equipped with a material ejector for ejecting waste and a waste collection box. The rotating shaft in the connecting rod, along with traction ropes one and two, allows the ejector pin and the collection box to move simultaneously by the same length. The sliding groove and recess in the material ejector device allow the ejector pin to move horizontally and vertically, respectively, and prevent the ejector pin from shifting upwards, ensuring that the ejector pin moves smoothly. The device pushes waste material out of the foam and into the collection box for safekeeping, preventing it from falling onto the workbench and affecting the normal operation of the cutting device. The elastic components one and two are designed so that when the traction ropes one and two apply tension to the moving block and the collection box, they are stretched. When the tension disappears, they rebound due to their elastic deformation properties, thus generating tension on the collection box and the moving block respectively, returning them to their initial positions and preparing them for the next waste collection cycle, thereby improving the reliability and stability of the equipment.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] A foam cutting machine, such as Figures 1-5 As shown, the device includes a workbench 1 and a cutting device 2 slidably connected thereto. The cutting device 2 cuts the foam on the workbench 1. The workbench 1 has fixing devices on both sides for securing the foam during operation. When the cutting device 2 cuts, it first cuts the small patterned parts that need to be removed. A support platform 4 is provided below the workbench 1, and a sliding rod 5 is slidably connected to the support platform 4. The support platform 4 provides support for the sliding rod 5, and has a sliding track on the support platform 4 to facilitate the sliding rod 5 sliding along the length of the workbench 1. A top-feeding device is slidably connected inside the sliding rod 5. The top-feeding device can be adjusted along the workbench 1 by sliding within the sliding rod 5. The position of the worktable 1 in the width direction is adjusted to match the movement of the worktable 1 in the length direction, positioning it below the waste material to be ejected. A driven rod 6 is installed above the worktable 1, and a storage box 7 is slidably connected inside the driven rod 6. The storage box 7 is used to collect small waste materials ejected from the foam by the ejector device, preventing the waste materials from falling onto the worktable 1 after being ejected and affecting the normal operation of the cutting device 2. The driven rod 6 and the sliding rod 5 are welded together by a connecting rod 8. A cavity 9 is opened inside the connecting rod 8, and a drive device is rotatably connected inside the cavity 9, with its two ends fixedly connected to the storage box 7 and the ejector device, respectively. A handle extending out of the cavity 9 is welded to the side of the drive device away from the worktable 1. The operator can then... Applying a pushing force to the handle causes it to rotate clockwise. At this time, the storage box 7 and the top-loading device move simultaneously by the same distance, and the distance they move is proportional to the rotation angle of the drive device. An adjustment groove 10, extending through the width of the connecting rod 8, is provided on the inner wall of the cavity 9. An adjustment rod 11, welded to the top-loading device, is slidably connected within the adjustment groove 10. The operator applies a pulling force to the adjustment rod 11, causing the top-loading device to move in a direction perpendicular to the worktable 1. The sliding rod 5 initially remains at one end of the worktable 1 along its length. When small scrap pieces cut from the foam need to be processed, the operator applies a pulling force to the connecting rod 8. External force causes the driven rod 6 and sliding rod 5 to move to the bottom of the channel 3 corresponding to the waste to be processed. Then, the operator holds the handle and makes the drive device move clockwise to adjust the position of the top material device and the collection box 7. The collection box 7 can help the operator determine the position of the top material device under the workbench 1. Finally, the adjusting rod 11 is pulled to make the adjusting rod 11 move the top material device upward to push the waste out and into the collection box 7, so that the waste is collected into the inside of the collection box 7. The height of the adjusting channel 10 is greater than the maximum value between the bottom surface of the collection box 7 and the ejector pin 16, ensuring that the ejector pin 16 can enter the collection box 7 during the upward movement.

[0022] like Figures 1-3As shown, the drive device includes a rotating shaft 12 and two traction ropes, 13 and 14. The rotating shaft 12 is rotatably connected to the inner wall of the cavity 9. One end of the traction rope 13 is attached to the top material device and drips molten metal onto it. After the molten metal cools, the traction rope 13 is connected to the top material device. The other end of the traction rope 13 is connected to the end of the rotating shaft 12 away from the cutting device 2 in the same way. One end of the traction rope 14 is connected to the storage box 7 after the molten metal cools, and the other end is connected to the rotating shaft. The end of 12 near the cutting device 2 is connected in the same way. When the operator applies a pulling force to the rotating shaft 12 to make the rotating shaft 12 rotate in a clockwise direction, the length of the first traction rope 13 and the second traction rope 14 wrapped around the rotating shaft 12 increases, thereby applying a pulling force to the top material device and the storage box 7, causing the top material device and the storage box 7 to move simultaneously toward the direction of the connecting rod 8, and the storage box 7 and the top material device move the same distance, thereby moving the storage box 7 and the top material device to the corresponding position of the waste that needs to be processed.

[0023] like Figures 2-6 As shown, the ejector device includes a movable block 15 and an ejector pin 16. The movable block 15 is welded to the end of the traction rope 13 away from the rotating shaft 12. The traction rope 13 changes the position of the ejector pin 16 by pulling the movable block 15. Two limiting plates 18 are integrally formed on both sides of the ejector pin 16 along the width direction of the sliding rod 5 on the movable block 15. The side of the two limiting plates 18 that is close to each other is recessed inward to form a groove 17. The groove 17 allows the ejector pin 16 to slide on its inner wall to move in the height direction. The groove 17 can limit the trajectory of the ejector pin 16 and prevent the ejector pin 16 from deviating when moving upward, thus preventing it from successfully ejecting the waste material from the foam. The ejector pin 16 is welded to the end of the adjusting rod 11 away from the connecting rod 8. When the connecting rod 8 is pulled, the adjusting rod 11 drives the ejector pin 16 to move upward and push out the waste. The storage box 7 has a feed port 19 facing the worktable 1. A rotating plate 20 that can cover the feed port 19 is rotatably connected to the inner wall of the feed port 19. A limiting strip 28 is fixedly connected to the bottom surface of the storage box 7 below the feed port 19. The limiting strip 28 can restrict the rotating plate 20 to rotate only upward and not downward. When the ejector pin 16 pushes out the waste and pushes the rotating plate 20 to rotate, the waste enters the interior of the storage box 7. When the waste is completely inside the storage box 7, the ejector pin 16 is moved downward. At this time, the waste will be separated from the ejector pin 16 and stored in the storage box 7 due to the obstruction of the rotating plate 20.

[0024] like Figures 4-6As shown, the top surface of the sliding rod 5 is recessed inward to form a T-shaped sliding groove 21. The moving block 15 is slidably connected to the inner wall of the sliding groove 21, and the outer peripheral wall of the moving block 15 is in contact with the inner wall of the sliding groove 21. The shape of the moving block 15 and the sliding groove 21 allows the moving block 15 to move along a fixed trajectory. The bottom surface of the driven rod 6 is recessed inward to form a T-shaped moving groove 24. The storage box 7 is slidably connected to the inner wall of the moving groove 24 via the slider 25, and the outer peripheral wall of the slider 25 is in contact with the inner wall of the moving groove 24. The inner wall of the T-shaped moving groove 24 can provide support for the storage box 7, so that the storage box 7 can be connected to the driven rod 6 without falling off. The inner side wall of the sliding groove 21 away from the connecting rod 8 is recessed inward to form a first receiving groove 22. An elastic element 23 is welded to the side of the first receiving groove 22 away from the connecting rod 8. The elastic element 23 is set as a disc spring. The other end of the elastic element 23 Welded to the movable block 15, the inner wall of the movable groove 24 away from the connecting rod 8 is recessed to form a second receiving groove 26. An elastic element 27 is welded to the side of the second receiving groove 26 away from the connecting rod 8. The elastic element 27 is set as a second disc spring. The other end of the elastic element 27 is welded to the slider 25. Both the first elastic element 23 and the second elastic element 27 are set as springs. When the first traction rope 13 and the second traction rope 14 apply tension to the movable block 15 and the storage box 7 respectively, the elastic element 23 and the second elastic element 27 will be stretched as the storage box 7 and the ejector pin 16 move. When the tension from the first traction rope 13 and the second traction rope 14 on the storage box 7 and the movable block 15 disappears, the elastic element 23 and the second elastic element 27 rebound due to their own elastic deformation properties, thereby generating tension on the storage box 7 and the movable block 15 respectively, causing the storage box 7 and the movable block 15 to slide away from the connecting rod 8 and return to the initial position.

[0025] Working Principle: A foam cutting machine first cuts small patterns to be removed from the foam. The foam is then fixed in place at the location with the through groove 3, corresponding to the parts to be cut. After the small patterns are cut, the operator pushes the connecting rod 8 to move the ejector pin 16 and the storage box 7 to the corresponding position of the through groove 3. Then, the operator holds the handle to rotate the rotating shaft 12 clockwise, increasing the length of the first traction rope 13 and the second traction rope 14 wound around the rotating shaft 12. This causes the first traction rope 13 and the second traction rope 14 to exert a pulling force on the moving block 15 and the storage box 7, moving the ejector pin 16 and the storage box 7 closer to the connecting rod 8 and below the waste material. Next, use the other hand to apply a pulling force to the adjusting rod 11, causing the adjusting rod 11 to slide upward on the inner wall of the adjusting groove 10. The adjusting rod 11 drives the ejector pin 16 to move upward, lifting the waste material. After the waste material is lifted, it pushes the rotating plate 20 into the storage box 7. When the lower surface of the waste material is higher than the highest point of the rotating plate 20 at that time, the ejector pin 16 is moved downward. At this time, the rotating plate 20 blocks the waste material from moving downward, thus keeping the waste material in the storage box 7 for storage. After completing the steps, release the handle. The ejector pin 16 and the storage box 7 move away from the connecting rod 8 and return to the initial position under the pulling force generated by the rebound of the elastic element 1 23 and the elastic element 27.
