Description

Technical Field

[0001] This utility model relates to the technical field of cotton sheet cutting machines, specifically an automatic counting cotton sheet cutting machine. Background Technology

[0002] Medical absorbent cotton pads are a type of medical absorbent cotton, distinguished only by their shape. They are a primary hygiene material used in the medical industry for wound dressing, protection, and cleaning. Before leaving the factory, medical cotton pads are cut to the required size and then packaged in boxes or bags. The quantity of cotton pads per box or bag is determined according to customer requirements.

[0003] An existing patent (publication number: CN209382395U) discloses an automatic counting cotton sheet cutting machine, including a frame, a cutting table horizontally arranged at the upper end of the frame, a rectangular opening on the cutting table, an offset platform inside the opening, and the height of the lower surface of the offset platform being higher than the height of the upper surface of the cutting table. A pusher assembly is provided on one side of the opening for pushing cotton sheet groups onto the offset platform. The machine also includes a cutting assembly, which is suspended between the pusher assembly and the offset platform by a support member. Below the offset platform is a drive assembly that drives it to reciprocate in a direction perpendicular to the pushing direction of the cotton sheet groups. The drive assembly drives the offset platform to reciprocate at intervals to offset multiple cotton sheet groups sequentially. The distance that the cylinder drives the offset platform to move is limited by a limit sensor to prevent the cylinder from driving the offset platform to move excessively.

[0004] However, the above technical solution still has certain defects. During the use of the above technical solution, the cutter can only cut the cotton sheet once each time it moves up and down. This may result in the cotton sheet not being completely cut off due to wear of the cutter after it is cut, resulting in poor cutting effect and requiring rework in the later stage, which affects production efficiency. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide an automatic counting cotton sheet cutting machine to solve the technical problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic counting cotton sheet cutting machine, including a support frame, a cutting mechanism fixedly connected to the top of the support frame, the cutting mechanism including a side plate, the side plate fixedly connected to the top of the support frame, a blade slidably connected to the side wall of the side plate, a sliding frame fixedly connected to the top of the blade, a motor fixedly connected to the top of the side plate, an infrared counter located next to the motor fixedly connected to the side wall of the cutting mechanism, the output end of the motor fixedly connected to the side wall of a cam, and the output end of the motor offset from the center of the cam, two sets of conveyor belts fixedly connected to the side of the side plate away from the blade, the two sets of conveyor belts being obliquely arranged on the side wall of the side plate.

[0007] As a preferred embodiment of this invention, a collection frame is fixedly connected to the side wall of the bracket, and the collection frame is located below the blade.

[0008] As a preferred embodiment of this utility model, a tensioning mechanism is fixedly connected to the top of the bracket. The tensioning mechanism includes two sets of sub-frames, which are fixedly connected to the top of the bracket, and a guide roller is rotatably connected between the two sets of sub-frames.

[0009] As a preferred technical solution of this utility model, a set of rotating arms is rotatably connected to the side walls of the two sets of sub-frames, and a torsion spring is provided at the connection point between the rotating arm and the sub-frame.

[0010] As a preferred embodiment of this utility model, two sets of tension rollers are rotatably connected between the two sets of rotating arms, with the two sets of tension rollers respectively close to the top and bottom ends of the rotating arms.

[0011] As a preferred embodiment of this utility model, the outer walls of the two sets of tension rollers abut against cotton sheets, the top of the cotton sheets are attached to the outer wall of the guide rollers, and the end of the cotton sheets extends from the inside of the side plate to the side near the blade.

[0012] As a preferred technical solution of this utility model, two sets of air collection chambers are fixedly connected to the side wall of the sub-frame. The two sets of air collection chambers are located on the upper and lower sides of the cotton pad, respectively, and multiple sets of fans are fixedly connected inside each set of air collection chambers.

[0013] In summary, the present invention has the following main advantages:

[0014] 1. This utility model pushes the cotton sheet to the required length so that the cutter can cut the cotton sheet smoothly. Each up-and-down reciprocating motion of the blade can cut the cotton sheet on both sides, thus ensuring that the cotton sheet is completely cut during the cutting process. It is not easy for the cotton sheet to be partially connected without being completely cut, which ensures the cutting effect, avoids rework in the later stage, and improves production efficiency.

[0015] 2. This utility model uses a torsion spring to drive the rotating arm to rotate, which causes the tensioning roller to tighten the cotton sheet to be cut. This keeps the cotton sheet flat when it enters between the two sets of conveyor belts, avoiding wrinkles when the cotton sheet is cut by the blade, which would affect the quality of the cut cotton sheet. This ensures the size of the produced cotton sheet and improves the yield. Attached Figure Description

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] The embodiments of this utility model will be described below based on its overall structure.

[0026] An automatic counting and cutting machine for cotton sheets, such as Figures 1 to 5As shown, the device includes a support 1, a cutting mechanism 3 fixedly connected to the top of the support 1, a side plate 301 fixedly connected to the top of the support 1, a blade 302 slidably connected to the side wall of the side plate 301, a sliding frame 303 fixedly connected to the top of the blade 302, a motor 305 fixedly connected to the top of the side plate 301, an infrared counter 6 located next to the motor 305 fixedly connected to the side wall of the cutting mechanism 3, the output end of the motor 305 fixedly connected to the side wall of the cam 304, and the output end of the motor 305 offset from the center of the cam 304, two sets of conveyor belts 306 fixedly connected to the side of the side plate 301 away from the blade 302, the two sets of conveyor belts 306 being obliquely arranged on the side wall of the side plate 301, and a collection frame 2 fixedly connected to the side wall of the support 1, the collection frame 2 being located below the blade 302.

[0027] The motor 305 drives the cam 304 to rotate, causing the cam 304 to rotate eccentrically around the output end of the motor 305, thereby continuously pushing the sliding frame 303 to move back and forth. This causes the sliding frame 303 to drive the blade 302 to slide back and forth. During the up-and-down movement of the sliding frame 303, the sliding frame 303 is counted once each time it passes the infrared counter 6. During the up-and-down movement of the blade 302, the two sets of conveyor belts 306 hold the cotton sheet 5, and under the push of the conveyor belts 306, the cotton sheet 5 extends out from inside the side plate 301, so that the cotton sheet 5 is cut by the blade 302. After the blade 302 cuts the cotton sheet 5 downwards, it cuts again at the same position on the cotton sheet 5 when the blade 302 slides upwards, thus ensuring that the cotton sheet 5 is completely cut off.

[0028] Please refer to this carefully. Figure 2 , Figure 3 and Figure 4 A tensioning mechanism 4 is fixedly connected to the top of the support 1. The tensioning mechanism 4 includes two sets of sub-frames 401, which are fixedly connected to the top of the support 1. Guide rollers 402 are rotatably connected between the two sets of sub-frames 401. A set of rotating arms 403 is rotatably connected to the side walls of each of the two sets of sub-frames 401. A torsion spring is provided at the connection point between the rotating arm 403 and the sub-frame 401. Two sets of tensioning rollers 404 are rotatably connected between the two sets of rotating arms 403. Near the top and bottom of the rotating arm 403, the outer walls of the two sets of tension rollers 404 abut against cotton sheets 5. The top of the cotton sheets 5 is attached to the outer wall of the guide roller 402, and the end of the cotton sheets 5 extends from the inside of the side plate 301 to the side near the blade 302. Two sets of air collection chambers 405 are fixedly connected to the side wall of the sub-frame 401. The two sets of air collection chambers 405 are located on the upper and lower sides of the cotton sheets 5, respectively. Multiple sets of fans 406 are fixedly connected inside each set of air collection chambers 405.

[0029] The conveyor belt 306 pushes the cotton sheet 5 through the side plate 301. When the cotton sheet 5 is subjected to a certain traction force, the cotton sheet 5 drives the rotating arm 403 to flip through the tension roller 404, causing the rotating arm 403 to flip and torsion spring. When the cotton sheet 5 is in a relaxed state, the torsion spring rebounds and pushes the rotating arm 403 to flip in the opposite direction, causing the tension roller 404 to flip in the opposite direction, thereby tightening the cotton sheet 5 and keeping the cotton sheet 5 in a taut state at all times.

[0030] In use, by pushing the cotton sheet 5 to the required length, the cutter can smoothly cut the cotton sheet 5. Each reciprocating motion of the blade 302 can cut the cotton sheet 5 on both sides, thus ensuring that the cotton sheet 5 is completely cut during the cutting process. It is not easy for the cotton sheet 5 to be partially connected without being completely cut, which ensures the cutting effect, avoids rework later and improves production efficiency. The parts not involved in this device are the same as or can be implemented by existing technology.
