Description

Technical Field

[0001] This utility model relates to a mask cutting device, belonging to the field of mask production technology. Background Technology

[0002] A face mask is a hygiene and epidemic prevention product, generally worn over the mouth and nose to filter the air entering the mouth and nose, thereby blocking harmful gases, odors, droplets, viruses, and other substances. It is made of materials such as gauze or paper. Face masks have a certain filtering effect on the air entering the lungs. Wearing a face mask is very effective when respiratory infectious diseases are prevalent or when working in dusty or polluted environments. Face masks can be divided into air-filtering face masks and air-supplying face masks.

[0003] In the current mask production and cutting process, the rotation speed of the mask fabric needs to be constantly adjusted during the conveying process to prevent the fabric from loosening or tearing due to stress. However, this method is complicated to operate, and it is difficult to quickly disassemble and replace the unwinding and rewinding equipment, which reduces the convenience of mask cutting and processing. In addition, when using a cutting roller, it is not convenient to quickly pass and fix the end of the fabric, and there are certain safety hazards when it is handled manually. Furthermore, it is difficult to effectively flatten the fabric during the cutting process, which can easily lead to wrinkles and reduce the quality of mask cutting and processing. Utility Model Content

[0004] The purpose of this invention is to provide a mask cutting device to solve the problems mentioned in the background art.

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

[0006] A mask cutting device includes a support frame, an output roller, and a take-up roller. The output roller is rotatably connected to the upper left inner side of the support frame, and the take-up roller is rotatably connected to the upper right inner side of the support frame. Mask fabric rolls are wrapped around the outer sides of both the output roller and the take-up roller. A rotating cutting roller is rotatably connected to the middle inner position of the support frame. A lifting cutting roller is provided above the rotating cutting roller. A discharge conveyor belt is rotatably connected to the lower right end of the support frame. A leveling roller is provided to the left side of the lifting cutting roller. The leveling roller is rotatably connected to the support frame. Guide clamping rollers are rotatably connected to both the left and right inner sides of the support frame.

[0007] Furthermore, a motor is fixedly connected to the upper right front side of the support frame, and a rotating chuck is fixedly connected to the rear end of the output shaft of the motor. The rotating chuck is slidably connected to the output roller.

[0008] Furthermore, a disassembly screw is spirally connected to the upper right side of the rear end wall of the support frame, a sliding chuck is rotatably connected to the front end of the disassembly screw, and a first turntable is fixedly connected to the rear end of the disassembly screw.

[0009] Furthermore, a pawl is rotatably connected to the upper front end of the unwinding roller, and an inner ratchet is slidably connected to the outer side of the pawl. The inner ratchet is fixedly connected to the support frame, and a torsion spring is provided on the surface of the rotating shaft between the pawl and the unwinding roller.

[0010] Furthermore, a fixed top frame is fixedly connected to the upper middle position of the support frame, and an adjusting screw is screwed to the middle position of the fixed top frame. A second turntable is fixedly connected to the upper end of the adjusting screw, and a lifting sleeve is screwed to the lower outer side of the adjusting screw. A lifting frame is fixedly connected to the lower end of the lifting sleeve. The lifting frame is rotatably connected to the lifting cutting roller. A limit telescopic rod is fixedly connected to the upper outer side of the lifting frame, and the limit telescopic rod is fixedly connected to the fixed top frame.

[0012] The beneficial effects of this utility model are:

[0013] This invention utilizes an output roller to unwind mask fabric rolls, and a take-up roller, powered by a motor, to rewind the cut fabric rolls. A rotating and lifting cutting roller enables continuous, one-time forming and cutting of the fabric rolls, improving the automation of mask cutting. It also allows for the recycling of waste materials. A ratchet and internal ratchet prevent excessive loosening of the output roller, ensuring the straightness of the fabric during transport and improving cutting quality. Rotation of the first turntable causes a screw to move the sliding chuck back and forth, facilitating the adjustment of the output and take-up rollers. This invention utilizes guide rollers to guide the fabric during disassembly and replacement. The rotation of the rotating cutting roller causes the gear set to drive the lifting gear and the lifting cutting roller to rotate in opposite directions. Simultaneously, a pulley system drives the leveling roller to rotate, facilitating the leveling of the fabric and preventing wrinkles that would reduce the quality of mask cutting. The rotation of the second turntable causes the adjusting screw to move the lifting sleeve up and down. Under the limiting action of the telescopic rod, the lifting frame can move the lifting cutting roller up and down, thus facilitating the passage of the mask fabric end through the rotating and lifting cutting rollers, improving the cutting effect of the mask fabric.

The rotating cutting roller 5 and the lifting cutting roller 6 enable continuous, one-time forming and cutting of the mask fabric roll 4, improving the automation of mask cutting and allowing for the recycling of waste materials. The ratchet 15 and internal ratchet 16 prevent the unwinding roller 2 from becoming excessively loose, ensuring the straightness of the mask fabric during transport and improving cutting quality. The rotation of the first turntable 14 causes the disassembly screw 12 to move the sliding chuck 13 back and forth, facilitating the unwinding process. Roller 2 and take-up roller 3 are disassembled and replaced. The guide clamping roller 9 guides the fabric. The rotation of the rotating cutting roller 5 causes the gear set 23 to drive the lifting gear 25 and the lifting cutting roller 6 to rotate in opposite directions. At the same time, the pulley set 24 drives the leveling roller 8 to rotate, so as to level the fabric and avoid wrinkles that would reduce the cutting quality of the mask. The rotation of the second turntable 19 causes the adjusting screw 18 to move the lifting sleeve 20 up and down. Under the limiting action of the limiting telescopic rod 22, the lifting frame 21 can drive the lifting cutting roller 6 up and down, so as to facilitate the passing of the mask fabric end through the rotating cutting roller 5 and the lifting cutting roller 6, thereby improving the cutting effect of the mask fabric.
