Description

Technical Field

[0001] This utility model relates to the field of cutting devices, specifically a cutting device for irregular shapes of foam plastics. Background Technology

[0002] The foam plastic irregular shape cutting device is an automated or semi-automated machine specifically designed to precisely cut various foam plastics such as EPS, EPE, and PU into non-standard and irregular shapes such as arcs, irregular parts, and customized contours. It can effectively solve the problem of complex shaping processing that is difficult to achieve with traditional straight cutting, and is currently widely used in many industries such as product packaging, building materials, children's toys, and home furniture.

[0003] Existing technologies generate a large amount of waste foam and lack a timely disposal mechanism, which occupies working space and is prone to causing fires. Large-sized waste foam lacks effective disposal methods, is prone to jamming or being unable to be collected, and is lightweight and fluffy, making it difficult to collect in a concentrated manner. Utility Model Content

[0004] The purpose of this invention is to provide a special-shaped cutting device for foam plastics, which has the advantages of avoiding the fire hazard that may be caused by the long-term accumulation of flammable foam, a classification and processing mechanism for foams of different sizes, improving the efficiency of the whole process from the generation to centralized treatment of waste foam, and preventing foam from entering the air and forming dust pollution, thus solving the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A special-shaped cutting device for foam plastic includes a worktable, a first slot at the upper end of the worktable, a first funnel block fixedly connected to the upper end of the worktable, a connecting pipe fixedly connected to the lower end of the first funnel block, a second funnel block fixedly connected to the lower end of the connecting pipe, limit mechanisms on both sides of the upper end of the worktable, a crushing mechanism on the inner wall of the connecting pipe, a storage box slidably installed on the inner wall of the first slot, and a fan fixedly connected to the inner wall of the storage box.

[0007] Preferably, the limiting mechanism includes side baffles fixed to both sides of the upper end of the worktable, a second slot is opened at the upper end of the side baffle, an electric cylinder is fixed to the lower end of the inner wall of the second slot, and an extension plate is fixed to the output end of the electric cylinder.

[0008] It is worth noting that the electric cylinder adjusts the height of the side baffle according to the size of the waste foam, and the side baffle prevents the crushed waste foam from falling into the outside of the device.

[0009] Preferably, the limiting mechanism further includes two third slots opened at the upper ends of the side baffle and the extension plate, a fourth slot is opened on the side wall of the third slot, a first motor is fixedly connected to the inner wall of the fourth slot, a rotating column is fixedly connected to the output end of the first motor, and two limiting blocks are fixedly connected to the side wall of the rotating column.

[0010] It is worth noting that the first motor drives two limit blocks to rotate, and when the two limit blocks rotate, they press the waste foam onto the upper part of the worktable.

[0011] Preferably, the crushing mechanism includes four connecting blocks fixed to the inner wall of the connecting pipe. The four connecting blocks are fixed to a fixed block at their close ends. A fifth slot is opened at the upper end of the fixed block. A second motor is fixed to the inner wall of the fifth slot. A blade is fixed to the output end of the second motor.

[0012] It is worth noting that large pieces of waste foam are shredded using a blade, and the shredded foam then falls into the storage box through a connecting tube.

[0013] Preferably, the inner wall of the storage box is fixed with a protective shell, and the fan is located inside the protective shell.

[0014] It is worth noting that the foam is drawn into the storage box by the fan, and the protective shell protects the fan to prevent the foam from affecting its normal operation.

[0015] Preferably, the upper end of the connecting tube is fixed to the funnel nozzle of the first funnel block, the second funnel block is inverted, the funnel nozzle of the second funnel block is fixed to the lower end of the connecting tube, and the funnel opening of the second funnel block is in contact with the upper end of the storage box.

[0016] It is worth noting that the purpose of the first funnel block is to allow more waste foam to fall into the storage box through the connecting pipe, while the second funnel block narrows the fan's air intake, which can increase negative pressure.

[0017] Preferably, a hole is provided through one side of the workbench, through which the storage box slides inside the workbench.

[0018] It is worth noting that the storage box is installed and removed through holes, making it easy to remove the waste foam inside.

[0019] Preferably, the blade is located inside the first funnel block, and the upper end of the blade is higher than the funnel mouth of the first funnel block.

[0020] It is worth noting that the upper end of the blade is higher than the funnel mouth of the first funnel block to prevent the foam from being too large or the funnel mouth from being too small, so that the foam cannot enter the funnel mouth and can be crushed by the blade.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] This utility model:

[0023] 1. Activate the electric cylinder according to the size of the waste foam. The electric cylinder pushes the extension plate to transfer the waste foam completely to the workbench, preventing the waste foam from accumulating directly in the cutting area. Subsequently, the waste foam is quickly processed by components such as fans and blades, cutting off the chain from accumulation to the generation of hidden dangers at the source and eliminating safety risks.

[0024] 2. The first motor drives the rotating column to rotate, continuously pressing the large foam onto the upper part of the workbench to prevent it from escaping the side baffle. After the large foam is compacted, it will come into contact with the blades on the workbench, and the blades will crush the large foam. The crushed foam particles will still be sucked into the collection box by the negative pressure generated by the fan, ensuring that all waste foam is collected and there is no spillage. There is no need to disassemble other components. After taking it out, the waste foam in the collection box can be centrally processed. The operation is convenient and greatly improves the efficiency of subsequent processing. Attached Figure Description

[0032] To address the problems of existing technologies that generate large amounts of waste foam with a lack of timely disposal mechanisms, occupy workspace, and are prone to fire, as well as the lack of effective handling methods for large-sized waste foam which is prone to jamming or inability to be collected, and the difficulty in collecting lightweight and fluffy foam, the following technical solutions are proposed. Please refer to [link / reference]. Figure 1-5 ;

The upper end of the connecting pipe 4 is fixedly connected to the funnel nozzle of the first funnel block 3. The second funnel block 5 is inverted. The funnel nozzle of the second funnel block 5 is fixedly connected to the lower end of the connecting pipe 4. The funnel opening of the second funnel block 5 is close to the upper end of the storage box 8. A hole is provided through one side of the workbench 1. The storage box 8 is slidably located inside the workbench 1 through the hole.

[0034] The limiting mechanism 6 includes side baffles 61 fixed to both sides of the upper end of the worktable 1. A second slot 62 is opened at the upper end of the side baffles 61. An electric cylinder 63 is fixed to the lower end of the inner wall of the second slot 62. An extension plate 64 is fixed to the output end of the electric cylinder 63. The limiting mechanism 6 also includes two third slots 65 opened at the upper ends of the side baffles 61 and the extension plate 64. A fourth slot 66 is opened on the side wall of the third slot 65. A first motor 67 is fixed to the inner wall of the fourth slot 66. A rotating column 68 is fixed to the output end of the first motor 67. Two limiting blocks 69 are fixed to the side wall of the rotating column 68.

[0035] The crushing mechanism 7 includes four connecting blocks 71 fixed to the inner wall of the connecting pipe 4. The four connecting blocks 71 are fixed to a fixing block 72 at their close ends. A fifth slot 73 is provided at the upper end of the fixing block 72. A second motor 74 is fixed to the inner wall of the fifth slot 73. A blade 75 is fixed to the output end of the second motor 74. The blade 75 is located inside the first funnel block 3, and the upper end of the blade 75 is higher than the funnel mouth of the first funnel block 3.

[0036] Working principle: First, the device is placed at the existing cutting end, and the existing robotic arm cuts the foam. After the foam is cut, a large amount of waste foam will be generated and accumulated. If it is not cleaned up in time, it will cause a huge safety hazard. The size of the cut waste foam is used to open the electric cylinder 63. The output end of the electric cylinder 63 pushes the extension plate 64 to move upward, so that the waste foam can be placed intact on the upper end of the workbench 1. Then, the first motor 67, the second motor 74 and the fan 9 are turned on. The fan 9 sucks the small particles of waste foam into the inside of the storage box 8 through the connecting pipe 4. The first motor 67 drives the rotating column 68 to rotate. When the rotating column 68 rotates, it continuously presses the large foam on the upper end of the workbench 1 to prevent the large foam from falling out of the middle of the two side baffles 61. When the rotating column 68 presses the large foam down, the large foam comes into contact with the blade 75. The blade 75 crushes the waste foam. The crushed foam is sucked into the inside of the storage box 8 by the fan 9 to prevent the waste foam from overflowing. After use, the storage box 8 is taken out through the hole in the side wall of the workbench 1 and the waste foam inside the storage box 8 is collected and processed.
