Description

Technical Field

[0001] The utility model relates to the technical field of pearl cotton rolling and cutting devices, in particular to a pearl cotton rolling and cutting device which can prevent wire drawing. Background Art

[0002] Pearl cotton is a new type of environmentally friendly packaging material. It is composed of countless independent bubbles produced by physical foaming of low-density polyethylene. During the production process, a winch is needed to reel it up. After reeling, the pearl cotton needs to be cut using a reeling and cutting device for the next reeling.

[0003] When the existing pearl cotton rolling and cutting device is used, the pearl cotton is first rolled up, and then the cutting device is used to cut it after the rolling is completed. The cutting device usually drives the blade to cut the pearl cotton by moving up and down. However, the existing cutting device is prone to wear when the blade is used for a long time, making the blade uneven, thereby causing wire drawing and entanglement in the pearl cotton cutting process, resulting in poor cutting effect, and then it needs to be regularly inspected and replaced. During the replacement process, the locking screws need to be frequently disassembled, making the disassembly more cumbersome, resulting in the cutting device cannot be used in time, thereby reducing the overall factory efficiency of the pearl cotton. Therefore, in view of the above problems, we propose a pearl cotton rolling and cutting device that prevents wire drawing and entanglement. Summary of the invention

[0004] The utility model aims to provide an anti-wiredrawing pearl cotton winding and cutting device to solve the problem that the existing cutting device is prone to wear when the blade is used for a long time, making the blade uneven, thereby causing wiredrawing during the pearl cotton cutting process, resulting in poor cutting effect, and then it needs to be regularly inspected and replaced. During the replacement process, the locking screws need to be frequently disassembled, making the disassembly more cumbersome, resulting in the cutting device cannot be used in time, thereby reducing the overall factory efficiency of the pearl cotton.

[0010] Preferably, the number of the compression springs is two, the number of the connecting rods is two, the fixed rod has an inverted "T" shape, the right end of the fixed rod passes through the cutting knife, and the inner side of the elastic rubber protrusion fits tightly with the outer side of the cutting knife.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] In the utility model, by arranging a compression spring, a connecting rod, a fixing rod and an elastic rubber protrusion, when the cutting knife needs to be replaced during regular inspection, the fixing rod is pulled outward so that the right end of the fixing rod leaves the cutting knife, and then the cutting knife is pulled out downward to disassemble the cutting knife. After the disassembly is completed, the cutting knife is replaced and the new cutting knife is put back to its original position. At this time, the elastic rubber protrusion squeezes and fixes the outer side of the cutting knife, and then the fixing rod is loosened. The compression spring provides a reverse force to drive the connecting rod and the fixing rod to move rightward, so that the fixing rod passes through the cutting knife to fix the cutting knife again. The device is convenient to disassemble and install, does not take much time, enables the cutting device to be used in time, and improves the whole operation of the pearl cotton. The factory efficiency of the whole body is improved, and at the same time, the uneven blade caused by the wear of the cutting knife causes the drawing of the pearl cotton cutting, so as to improve the cutting quality of the pearl cotton. The cutting device is composed of a limit plate, a connecting block, a cutting knife, a compression spring, a connecting rod, a fixing rod and an elastic rubber protrusion. The limit plate presses the pearl cotton on the cutting table, so that when the cutting device cuts the pearl cotton, the wrinkles of the pearl cotton are reduced, the cutting effect is better, and the drawing is reduced. By setting a second motor and a screw, the second motor drives the screw to rotate, and the screw drives the cutting device to slide left and right as a whole through the connecting assembly and the second electric telescopic rod, so that the cutting device cuts the pearl cotton, and the left and right sliding has a better cutting effect on the pearl cotton.
