Description

Technical Field

[0001] The present application relates to the field of wet wipes folding, and in particular to a wet wipes folding machine with high working efficiency. Background Art

[0002] Conventional wet wipes folding machines often cannot achieve batch continuous folding operations when folding wet wipes, resulting in reduced folding efficiency.

[0003] At present, a Chinese utility model patent with announcement number CN220011489U has announced a cleaning wet wipes slicing and folding machine, including a workbench, a slicer, a reset device and a conveyor. The slicer and the reset device are arranged on the workbench, and the conveyor is located on the side of the workbench away from the slicer. A groove is provided on the workbench, and a folding plate is rotatably connected in the groove. The pressing plate is installed on the workbench through a rotating component and is located on the side of the groove close to the folding plate. The driving component drives the folding plate to rotate, and the wet wipes to be folded are cut by the slicer and sent to the folding plate. The driving component drives the folding plate to rotate, and the rotation of the folding plate drives the wet wipes to be folded on the pressing plate. Then the rotating component drives the pressing plate to rotate clockwise, and the wet wipes slide off the pressing plate and are transported by the conveyor, thereby achieving the folding effect of the wet wipes and avoiding damage to the wet wipes due to friction.

[0004] Since the folding plate needs to be reset after folding the wet wipes, the next wet wipe cannot be folded during this process. Therefore, the slicer needs to be stopped synchronously during the reset process, resulting in a long folding operation time for the wet wipes and poor efficiency. Summary of the invention

[0005] In order to improve the efficiency of wet wipes folding, the present application provides a wet wipes folding machine with high working efficiency.

[0006] The present application provides a wet wipes folding machine with high working efficiency, which adopts the following technical solution: A wet wipes folding machine with high working efficiency comprises a frame, a rotating wheel, a plurality of folding devices and a driving motor, wherein the frame is located between a wet wipes slicer and a conveyor, the rotating wheel is rotatably connected to the frame, the driving motor is used to drive the rotating wheel to rotate, the folding device comprises a folding plate, a pressing plate and a rotating member, the folding plate is arranged on the rotating wheel, and the rotating member is used to drive the pressing plate to rotate and fold the wet wipes located on the folding plate and the pressing plate.

[0007] By adopting the above technical solution, after the wet wipes slicer completes slicing of the wet wipes, the wet wipes are transported to the folding device, the driving motor drives the rotating wheel to rotate, and the rotating wheel drives the folding device to move. During the rotation of the rotating wheel, the rotating member drives the pressing plate to rotate, and the pressing plate and the folding plate fold the wet wipes. After that, the folded wet wipes are sent to the conveyor. At this time, the rotating member drives the pressing plate to rotate in the opposite direction, so that the pressing plate moves away from the folding plate. During this process, the remaining folding devices on the rotating wheel are used to receive the wet wipes cut by the subsequent wet wipes slicer. The subsequent reset time of the pressing plate and the folding plate does not affect the discharge speed of the wet wipes slicer, and the wet wipes slicer does not need to stop, and the efficiency of wet wipes folding is greatly improved. Optionally, the folding device also includes a connecting member for connecting the folding plate and the pressure plate, the connecting member includes a connecting plate, a first gear and a second gear, one end of the connecting plate is rotatably connected to the folding plate, the other end of the connecting plate is arranged on the pressure plate, the first gear is arranged on the folding plate, the second gear is rotatably connected to the pressure plate, the first gear is meshed with the second gear, and the rotating member is used to drive the second gear to rotate.

[0008] By adopting the above technical solution, the rotating member drives the second gear to rotate, the second gear is meshed with the first gear, and one end of the connecting plate is rotatably connected to the folding plate, and the other end of the connecting plate is rotatably connected to the pressure plate. Therefore, the second gear can rotate around the first gear, and the pressure plate rotates toward the folding plate. The folding plate can rotate to a state parallel to the pressure plate, and the connecting member makes the rotation of the pressure plate more reasonable.

[0009] Optionally, the rotating member includes a rack, a rotating motor and a reciprocating screw, the rack is slidably connected to the pressure plate, the rack is meshed with the second gear, the length of the reciprocating screw is parallel to the sliding direction of the rack, the reciprocating screw is rotatably connected to the pressure plate, the rack is threadedly connected to the reciprocating screw, and the rotating motor is used to drive the reciprocating screw to rotate.

[0010] By adopting the above technical solution, the rotating motor drives the reciprocating screw to rotate, the reciprocating screw drives the rack to move, the rack is meshed with the second gear, the second gear rotates relative to the first gear, and the second gear can drive the pressure plate to move in the direction of the folding plate until the pressure plate and the folding plate fold the wet wipes. The reciprocating screw can drive the rack to move back and forth. After the wet wipes are folded, the rotating motor does not need to change the direction, the reciprocating screw can drive the rack to slide in the opposite direction, and the pressure plate is reset. The rotating part has a simple structure and is easy to operate.

[0011] Optionally, the diameter of the second gear is greater than the diameter of the first gear.

[0012] By adopting the above technical solution, since the pressing plate and the folding plate need to fold the wet wipes, the pressing plate and the folding plate approach each other until they remain parallel during the folding process, that is, the pressing plate rotates 180° relative to the folding plate, and the rotating part also rotates with the pressing plate during the transmission process. The diameter of the second gear is greater than the diameter of the first gear, so that the rack cannot contact the first gear, and the structure of the rotating part is more reasonable.

[0013] Optionally, a first adjustment member for adjusting the position of the wet wipes is provided on the folding plate, and the first adjustment member includes a transmission belt, two transmission rollers, a transmission motor and an infrared detector. The two transmission rollers are distributed along the transportation direction of the wet wipes, and the transmission rollers are rotatably connected to the folding plate. The transmission belt is sleeved on the transmission rollers, and the transmission motor is used to drive the transmission rollers to rotate. The infrared detector is used to detect the position of the wet wipes, and the infrared detector is electrically connected to the transmission motor.

[0014] By adopting the above technical solution, the wet wipes slicer transports the wet wipes to the folding machine after completing slicing. During the transportation process, there is always a situation where the folding line of the wet wipes is not located between the folding plate and the pressing plate, the folded wet wipes cannot be aligned, and the folding effect of the wet wipes is not good. The position of the wet wipes is detected by an infrared detector. When the position of the wet wipes does not meet the requirements, the infrared detector can drive the drive motor to start, the drive motor drives the transmission roller to rotate, the transmission roller drives the transmission belt to rotate, and the wet wipes are moved by the transmission belt until they meet the folding requirements. The first adjustment member improves the folding effect of the wet wipes.

[0015] Optionally, a negative pressure box is provided on the folding plate, and the negative pressure box is located inside the transmission belt. The transmission belt is evenly distributed with through holes connected to the negative pressure box. The folding device also includes an adsorption member used for the negative pressure box to generate negative pressure and allow the wet wipes to be adsorbed on the transmission belt.

[0016] By adopting the above technical solution, one part of the wet wipe is located on the pressure plate and the other part of the wet wipe is located on the folding plate. During the rotation of the pressure plate, the wet wipe will be displaced as the pressure plate rotates. Therefore, during the rotation of the pressure plate, the adsorbent generates negative pressure in the negative pressure box. The negative pressure box keeps the wet wipe in contact with the transmission belt through the through hole, thereby reducing the displacement of the wet wipe due to the rotation of the pressure plate during the folding process, and further improving the folding effect of the wet wipe.

[0017] Optionally, the adsorption component includes a push rod, a sealing disk, a tube body and a connecting tube, the tube body is arranged on the pressure plate, one end of the connecting tube is connected to the tube body, and the other end of the connecting tube is connected to the negative pressure box, the sealing disk is slidably connected to the tube body, and the push rod is used to drive the sealing disk to slide.

[0018] By adopting the above technical solution, the staff pushes the push rod, which drives the sealing plate to move in the tube body. After the air pressure in the tube body becomes smaller, negative pressure is generated in the negative pressure box through the connecting pipe, and the wet wipes are adsorbed on the transmission belt through the through holes on the transmission belt, reducing the displacement of the wet wipes during the folding process.

[0019] Optionally, the adsorption part also includes a first bevel gear, a second bevel gear and a screw, the first bevel gear is coaxially arranged with the second gear, the first bevel gear is arranged on the second gear, the length of the screw is parallel to the length direction of the push rod, the screw is rotatably connected to the pressure plate, the push rod is threadedly connected to the screw, the second bevel gear is coaxially arranged with the screw, the second bevel gear is arranged on the screw, and the first bevel gear is meshed with the second bevel gear.

[0020] By adopting the above technical scheme, during the rotation of the pressure plate, the second gear rotates relative to the first gear, and the second gear drives the pressure plate to rotate relative to the folding plate. While the second gear rotates, the second gear drives the first bevel gear to rotate, the first bevel gear drives the second bevel gear to rotate, the second bevel gear drives the screw to rotate, the screw drives the push rod to move, and the push rod drives the sealing disk to move in the tube body, so that the air pressure in the tube body becomes smaller, and negative pressure is generated in the negative pressure box. The wet wipes are adsorbed on the transmission belt through the through holes on the transmission belt. The adsorption element does not need to be operated by the staff. In the process of folding the wet wipes by the pressure plate and the folding plate, the position of the wet wipes relative to the pressure plate remains unchanged, thereby improving the folding effect of the wet wipes. In the process when the wet wipes need to be separated from the folding device and enter the conveyor, the pressure plate rotates in the direction away from the folding plate. At this time, the adsorption element operates in the opposite direction, so that the air pressure in the negative pressure box becomes larger, and the through holes on the transmission belt blow the wet wipes, making it easier for the wet wipes to enter the conveyor.

[0021] Optionally, the connecting pipe is a hose.

[0022] By adopting the above technical solution, since the adsorption component is located on the pressure plate, the negative pressure box is located on the folding plate, the pressure plate can rotate relative to the folding plate, and the connecting pipe is a hose, the structure is more reasonable.

[0023] Optionally, the height of the conveyor is lower than the height of the rotating wheel axis, and when the height of the pressure plate is higher than the rotating wheel axis, the pressure plate is always in a horizontal state and the pressure plate is close to the folding plate.

[0024] By adopting the above technical solution, the folding plate rotates with the rotating wheel, and the pressure plate rotates relative to the folding plate. Relative to the frame, the folding plate is driven by the rotating wheel to approach the pressure plate in a horizontal state and fold the wet wipes. In this process, the adsorbent reduces the movement of the wet wipes relative to the folding plate and reduces the occurrence of the wet wipes detaching from the folding plate. After the wet wipes are folded, the folding device rotates with the rotating wheel until the height of the pressure plate is lower than the axis of the rotating wheel. At this time, the rotating part drives the pressure plate to move away from the folding plate. At this time, the wet wipes are located on the pressure plate. Under the opposite action of gravity and the adsorbent, the wet wipes fall onto the conveyor whose height is lower than the axis of the rotating wheel.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. Several folding devices are arranged on the rotating machine, which realizes the folding operation of wet wipes at multiple stations, reduces the occurrence of the slicer downtime, and improves the working efficiency of wet wipes folding; 2. The first adjusting member is used to adjust the position of the wet wipes delivered by the wet wipes slicer to the folding device. Adjusting the position of the wet wipes can improve the folding effect and quality of the wet wipes; 3. The adsorbent is used to adsorb the wet wipes on the transmission belt when the pressure plate rotates toward the abutment plate, and is used to blow the wet wipes when the pressure plate rotates away from the abutment plate to facilitate the wet wipes to enter the conveyor.
