Description

Technical Field

[0001] This utility model belongs to the field of dust collection by cutting, and specifically relates to a dust collection device with a protective structure. Background Technology

[0002] Slitting equipment is a mechanical device that cuts wide sheets of paper, mica tape, or film into multiple narrow strips of material. In modern industrial production processes, slitting equipment is widely used for cutting rolls of materials such as paper, film, and fabric.

[0003] However, the slitting process generates a large amount of debris, dust, and other impurities. If these impurities are not treated in time, they can easily scatter in the production environment, affecting the normal operation of the equipment and the cleanliness of the production environment. In addition, dust accumulation in the air may pose a threat to the health of operators. Therefore, the application of dust collection devices has become inevitable. However, when using traditional slitting dust collection devices, the process of replacing the cutter is often cumbersome, requiring a lot of time and effort to disassemble and install. Moreover, the dust collection device may become clogged due to dust accumulation, making subsequent cleaning very troublesome, affecting the normal operation of the equipment, and reducing work efficiency.

[0004] Therefore, a cutting and dust collection device with a protective structure is proposed, which features convenient blade replacement, reduced risk of pipe blockage, easy disassembly and assembly, and convenient maintenance. Utility Model Content

[0005] To overcome the problems of cumbersome blade replacement, easy clogging of dust collection devices, and inconvenience in later maintenance of existing slitting and dust collection devices.

[0006] The technical solution of this utility model is as follows: a cutting and dust collection device with a protective structure, including a box; a collection component is provided on the upper part of the inner wall of the box, the collection component includes a first pipe, a cylinder, a transparent cover, a dust suction port, a filter screen and a disc, the first pipe is fixedly connected to the upper part of the inner wall of the box, the cylinder is threadedly installed on the lower end of the outer wall of the first pipe, the transparent cover is fixedly connected to the lower end of the cylinder, the filter screen is provided inside the transparent cover, the disc is fixedly connected to the lower outer wall of the filter screen, the upper end face of the disc is in contact with the lower end face of the transparent cover, the dust suction port is threadedly installed on the lower outer wall of the transparent cover, the side wall of the disc is fixedly connected to the inner wall of the dust suction port, a cutting component is provided in the upper middle part of the inner wall of the box, and a transmission component is provided in the middle of the box.

[0007] Preferably, the cover plate is removed using screws, and the film passes through the second slot at the front of the housing, over the upper end of the second tension roller. Since a semi-circular block is fixed to the upper inner wall of the second slot, damage to the film during sliding is prevented. Then, the film passes around the outer walls of the three first tension rollers and exits through the second slot at the rear of the housing. Subsequently, the cutter is installed on the inner wall of the U-shaped slot, and the distance between the cutter and the film is adjusted. Since the U-shaped slot and the threaded groove are interconnected, the cutter is fixed using bolts passing through the threaded groove. This simple operation facilitates easy replacement of the cutter. Then, close the cover. When the film begins to slide, turn on the air pump. When the film is cut by the cutter, most of the dust generated is sucked into the suction port. The dust passes through the suction port, filter, cylinder, first pipe, second pipe and third pipe, and finally reaches the first collection box. The filter inside the transparent cover will block larger dust particles, preventing the pipes from getting blocked, which would make subsequent processing troublesome and affect work efficiency. This solves the problems of cumbersome cutter replacement, easy blockage of the dust collection device and inconvenience of later maintenance in the existing cutting and dust collection device.

[0008] Preferably, the collection assembly also includes an air pump, a second pipe, a third pipe, and a first collection box. The air pump is located on the right side of the outer wall of the box. The air inlet of the air pump is fixedly connected to the second pipe. The other end of the second pipe passes through the outer wall of the box and is fixedly connected to the right end of the first pipe. The air outlet of the air pump is fixedly connected to the third pipe. The other end of the third pipe is fixedly connected to the first collection box. In use, by turning on the air pump, the dust and impurities inside the first pipe are sucked into the second and third pipes and finally reach the first collection box for collection, which is convenient and quick.

[0009] Preferably, the cutting assembly includes a support column, a first fixing block, a second fixing block, a U-shaped groove, a threaded groove, a bolt, and a cutter. The support column is fixed to the upper part of the inner wall of the housing, and multiple first fixing blocks are fixed to the outer wall of the support column. A second fixing block is fixed to the side wall of the first fixing block. A U-shaped groove is formed through the upper end of the second fixing block, and a threaded groove is formed through the side wall of the second fixing block. The U-shaped groove and the threaded groove are interconnected. A bolt is threaded onto the inner wall of the threaded groove, and a cutter is movably installed on the inner wall of the U-shaped groove. The other end of the bolt passes through the threaded groove and fits against the side wall of the cutter. In use, the cutter is placed into the inner wall of the U-shaped groove, and the bolt is rotated. Because the U-shaped groove and the threaded groove are interconnected, the other end of the bolt will fit tightly against the side wall of the cutter and fix it. Disassembly and assembly are simple, and the cutter can be easily replaced.

[0010] Preferably, the transmission assembly includes a first tension roller and a film. Three first tension rollers are fixedly connected to the middle of the inner wall of the housing. The positions of the first tension rollers are arranged in a triangular pattern. The film is slidably installed on the outer wall of the first tension rollers. In use, the film slides on the outer wall of the first tension rollers. Since the positions of the first tension rollers are arranged in a triangular pattern, it helps to maintain the stability of the film during the movement process and reduces the possibility of the film deviating or running off course during the transport process.

[0011] Preferably, a second slot is provided through the front and rear side walls of the box. A semi-circular block is fixed to the upper end of the inner wall of the second slot, and a second tension roller is fixed between the left and right inner walls of the second slot. In use, when the film passes through the upper end of the second tension roller and the lower end of the semi-circular block, the side walls of the second tension roller and the side walls of the semi-circular block can prevent the film from being damaged.

[0012] Preferably, a second collection box is movably installed on the lower end of the inner wall of the box. The upper end of the second collection box has multiple through holes, and the left end of the second collection box has an arc-shaped groove. During use, some of the dust generated by cutting will fall freely and enter the interior of the second collection box through the through holes for collection.

[0013] Preferably, a third slot is provided through the lower left end of the box. The inner wall of the third slot is adapted to the outer wall of the second collection box. A door is hinged to the inner edge of the third slot. A cover plate is fixed to the upper end of the box with screws. When in use, the second collection box can be taken out for cleaning by opening the door. The operation is simple. The upper end of the box and the cover plate are fixed with screws, which is convenient for disassembly and maintenance of internal parts.

[0014] The beneficial effects of this utility model are:

[0015] 1. By installing the cutter on the inner wall of the U-shaped groove and adjusting the distance between the cutter and the film, and since the U-shaped groove and the threaded groove are interconnected, the cutter is fixed by bolts passing through the threaded groove. The operation is simple; if replacement is needed, simply rotate the bolts to remove the blade. Disassembly and assembly are simple, solving the problem of cumbersome cutter replacement in existing slitting and dust collection devices.

[0016] 2. By turning on the air pump, when the membrane is cut by the cutter, most of the dust generated is sucked into the suction port. The dust passes through the suction port, filter screen, cylinder, first pipe, second pipe, and third pipe, finally reaching the first collection box. The filter screen inside the transparent cover blocks larger dust particles, preventing pipe blockage, which would complicate subsequent processing and affect work efficiency. A small amount of dust that falls will pass through the through hole and enter the interior of the second collection box for collection. The second collection box can be removed for cleaning by opening the door. The operation is simple. The top of the box and the cover are fixed with screws, which is convenient for disassembly and maintenance of internal parts. This solves the problem that the existing cutting dust collection device is prone to blockage during use and is inconvenient for later maintenance.

[0017] 3. During use, the film slides on the outer wall of the first tension roller. Since the position of the first tension roller is triangularly distributed, it helps to maintain the stability of the film during movement and reduces the possibility of the film deviating or running off course during transport. When the film passes through the upper end of the second tension roller and the lower end of the semicircular block, the side walls of the second tension roller and the side walls of the semicircular block can prevent the film from being damaged.
