Description

Technical Field

[0001] The utility model relates to the technical field of alcohol cotton pad processing, in particular to a shearing device for the production and processing of alcohol cotton pads. Background Technique

[0002] Alcohol cotton pads are generally made of clean cotton dipped in about 75% medical alcohol solution. The alcohol cotton pads used for traditional Chinese medicine cupping are generally dipped in alcohol solution with more than 90%.

[0003] In the prior art, the Chinese utility model content with the publication number of CN213447795U discloses an alcohol cotton pad shearing and separating device, including a bearing plate. A concave plate is fixedly connected to the top end of the bearing plate. A fixed plate is arranged at the bottom of the inner cavity of the concave plate. A cutting blade is fixedly connected to the bottom end of the fixed plate. The middle part of the top end of the fixed plate is hinged with a linkage push rod. A turntable is arranged at the top of one side of the linkage push rod. The side of the other side of the turntable is rotationally connected with the top of the linkage push rod. A driving mechanism is arranged on the other side of the turntable. A rectangular through hole is opened in the middle of the top end of the bearing plate. A bearing mechanism is arranged in the inner cavity of the rectangular through hole. By rotating the turntable, the linkage push rod is driven to rotate and move up and down, so as to drive the fixed plate to move up and down in the inner cavity of the concave plate, so that the cutting blade at the bottom end of the fixed plate can move up and down in a reciprocating manner, so as to realize equidistant shearing of the non-woven fabric placed on the bearing mechanism, improve the working efficiency, and save the tediousness and high difficulty of manual shearing.

[0004] In the above technical solution, by driving the fixed plate to move up and down periodically inside the concave plate, the cotton pads are divided by the cutting blade. When the first cutting blade and the second cutting blade move downward and contact the conveyor belt to divide the cotton pads, because the conveyor belt is soft, it is difficult for the cutting blade to cut the cotton pads on the conveyor belt, and at the same time, the cutting blade is easy to damage the conveyor belt, and the cotton pads cannot be separated and disconnected, affecting the shearing efficiency of the cotton pads.

A translation component 13 for moving the installation plate 8 is arranged in the inner cavity of the through groove 7;

[0023] Through the cooperation of the driving roller 2 and the conveying belt 5, it is convenient to convey the cotton pads. At the same time, during the conveying process, the driving rollers 2 on both sides can limit the cotton pads, and the cutting knives 3 on the driving roller 2 in the middle position can cut the cotton pads to form strip-shaped cotton pads. The strip-shaped cotton pads are continuously conveyed and are sheared again by the rotating shearing knife 11 in cooperation with the support table 17. During the slitting process, the shearing quality can be guaranteed, the phenomenon of unable to cut off can be avoided, and at the same time, the size of the shearing can be adjusted, which can improve the shearing efficiency of the cotton pads.

[0024] The driving component 6 includes a worm 61 rotatably installed on the inner side of the fixed frame 1 through a support seat. A worm gear 62 meshing with the worm 61 is fixed on the outer side of the driving roller 2. A driving motor 63 is fixed on the outer side of the fixed frame 1. The output shaft of the driving motor 63 penetrates to the inner side of the fixed frame 1 and is fixed with a driving bevel gear 64. One end of the worm 61 penetrates the support seat and is fixed with a driven bevel gear 65 meshing with the driving bevel gear 64. The driving motor 63 drives the driving bevel gear 64 to rotate, and then the worm 61 is driven to rotate by the driven bevel gear 65, and the three groups of driving rollers 2 are synchronously driven in cooperation with the worm gear 62, which is convenient to convey the cotton pads through the conveying belt 5.

Through the arrangement of the support table 17, it is ensured that the shearing knife 11 has sufficient supporting force to shear the cotton sheet.

[0029] During specific use, the cotton sheet to be cut is placed between the driving roller 2 and the conveyor belt 5. Then, the driving motor 63 is started. The driving motor 63 drives the driving bevel gear 64 to rotate. Then, the driving bevel gear 64 drives the driven bevel gear 65 to drive the worm 61. Subsequently, the worm 61 drives the driving roller 2 to rotate through the worm gear 62. The driving roller 2 presses the cotton sheet, and with the cooperation of the conveyor belt 5, the cotton sheet is transferred to the right. During the transfer process, the slitting knife 3 on the driving roller 2 at the middle position preliminarily cuts the cotton sheet to form strips. Then, the strip-shaped cotton sheet continues to be conveyed to the right. Then, the servo motor 12 drives the tool holder 10 and the shearing knife 11 to rotate through the rotating shaft 9, and cooperates with the support table 17 to cut the strip-shaped cotton sheet again, cutting the cotton sheet into small pieces.
