Description

Technical Field

[0001] This application relates to the field of slicing cotton towels, and more particularly to a slicing device for cotton towels. Background Technology

[0002] Soft towels are nonwoven fabrics made from fibers such as cotton and viscose, processed using nonwoven processes such as spunlace and then cut into dry towel products of different sizes, which are commonly used for people's daily cleaning and care.

[0003] Currently, Chinese utility model patent CN220994684U discloses an integrated device for slicing and discharging cotton towels. The device includes a workbench, a mounting frame fixed above the workbench, a drive motor externally mounted on the mounting frame, a movable block below the mounting frame, an electric telescopic rod mounted at the bottom of the movable block, a fixed block below the electric telescopic rod, a fixed frame mounted on the side of the fixed block, a movable rod connected internally to the fixed frame, a handle fixed to one end of the movable rod, a movable plate fixed to the outer wall of the movable rod, a spring fixed to the side of the movable plate, and a mounting groove internally formed in the fixed block, with a fixed seat connected inside the mounting groove. This utility model facilitates the disassembly of the slicing mechanism, thereby improving maintenance efficiency.

[0004] The general production sequence of soft towels is rewinding, edge pressing, punching, trimming, glue spraying, slicing, and flattening. Before the slicing operation, the soft towel has already been rewound into a long strip of paper with three or four layers. Directly slicing the soft towel can easily cause the soft towel to move relative to the slicing mechanism, resulting in burrs at the cut and multiple layers of varying lengths, leading to low production quality. Utility Model Content

[0005] In order to reduce the movement of the soft towel relative to the slicing mechanism during the slicing process, this application provides a slicing device for the soft towel.

[0006] This application provides a slicing device for soft towels, which adopts the following technical solution:

[0007] A slicing device for a soft towel includes a frame, a conveying mechanism, and a slicing mechanism. The slicing mechanism includes a slicing blade, a mounting frame, a slicing cylinder, a pressure plate, and a clamping spring. The mounting frame is slidably connected to the frame in a direction close to or away from the soft towel. The slicing cylinder is used to drive the mounting frame to move. The slicing blade is disposed on the frame. The pressure plate is slidably connected to the mounting frame in a sliding direction. The clamping spring is used to keep the soft towel pressed before the slicing blade cuts it. The conveying mechanism is used to transport the soft towel toward the slicing mechanism.

[0008] By adopting the above technical solution, the conveying mechanism is used to drive the soft towel to move from the frame towards the slicing mechanism. When the soft towel moves to the slicing mechanism, the piston rod of the slicing cylinder extends, the mounting bracket moves towards the soft towel, and the pressure plate abuts against the soft towel until the compression spring contracts. At this time, the multi-layer soft towel structure is clamped on the conveying mechanism. Then, the piston rod of the slicing cylinder continues to extend until the slicing blade cuts the soft towel, completing the cutting of the soft towel. During the cutting process, the multi-layer soft towel is pressed tightly on the conveyor belt, reducing the movement of the soft towel relative to the slicing mechanism, reducing the generation of burrs on the soft towel after cutting, improving the uniformity of the cut soft towel, and greatly improving the quality of the soft towel.

[0009] Optionally, the slicing mechanism further includes a mounting component for mounting the slicing blade. The mounting component includes a mounting block and a mounting spring. The mounting frame has a mounting hole for placing the slicing blade. The mounting block is slidably connected to the mounting frame along a direction perpendicular to the thickness of the slicing blade. The slicing blade has a locking groove for the mounting block to engage. The mounting spring is used to hold the mounting block in the locking groove.

[0010] By adopting the above technical solution, the slicing blade needs to be replaced periodically after long-term use. The operator can move the mounting block away from the snap-fit ​​groove to overcome the elasticity of the mounting spring, and the slicing blade can be taken out from the mounting hole. After the new slicing blade is placed in the mounting hole, the operator releases the mounting block, and the mounting block enters the snap-fit ​​groove under the action of the mounting spring, thus completing the replacement of the slicing blade. The mounting component has a simple structure and is easy for operators to operate.

[0011] Optionally, the conveying mechanism includes a conveyor belt, two conveyor rollers, and a conveyor motor. The two conveyor rollers are distributed along the transport direction of the towel. The conveyor rollers are rotatably connected to the frame. The conveyor belt is sleeved on the conveyor rollers. The conveyor motor drives the conveyor rollers to rotate.

[0012] By adopting the above technical solution, when the soft towel needs to move toward the slicing mechanism, the conveyor motor drives the conveyor roller to rotate, the conveyor roller drives the conveyor belt to move, and the conveyor belt drives the soft towel to move. The conveyor mechanism has a simple structure and is easy to maintain.

[0013] Optionally, the frame is provided with an adsorption element for reducing the movement of the soft towel relative to the conveyor belt. The conveyor belt has several through holes evenly distributed on it. The adsorption element includes an adsorption frame, an adsorption pump, and a filter box. The adsorption frame is located between the conveyor belts and abuts against the inner sidewall of the conveyor belt. The adsorption pump is used to generate negative pressure inside the adsorption frame. The filter box is located between the adsorption frame and the adsorption pump and is used to reduce the entry of lint from the soft towel into the adsorption pump.

[0014] By adopting the above technical solution, the slicing mechanism requires the conveying mechanism to be stopped when cutting the soft towel. Therefore, the conveying mechanism needs to operate intermittently. Intermittent operation can easily cause the soft towel to move relative to the conveyor belt due to inertia, resulting in a change in the cutting position. The adsorption component is used to reduce the movement of the soft towel relative to the conveyor belt. The adsorption pump creates negative pressure in the adsorption frame. The adsorption frame, through the through holes of the conveyor belt, allows the soft towel to be adsorbed onto the surface of the conveyor belt, increasing the friction between the soft towel and the conveyor belt and reducing the movement of the soft towel relative to the conveyor belt. During the adsorption process, the lint on the soft towel will enter the adsorption frame. The filter box reduces the amount of lint entering the adsorption pump, extending the service life of the adsorption pump.

[0015] Optionally, the frame is provided with a guiding mechanism for guiding the soft towel to enter the slicing mechanism at the same position. The guiding mechanism includes two guide plates, an adjusting screw, and a linkage. The two guide plates are distributed along the width direction of the soft towel and are slidably connected to the frame along the width direction of the soft towel. The length direction of the adjusting screw is parallel to the sliding direction of the guide plate, and the adjusting screw is threadedly connected to the frame. The adjusting screw is rotatably connected to one of the guide plates, and the linkage is used to drive the two guide plates to move closer to or further apart from each other.

[0016] By adopting the above technical solution, the guiding mechanism guides the soft towel smoothly into the slicing mechanism, ensuring that the soft towel is positioned in the center of the slicing blade, thus ensuring even force distribution on the slicing blade and extending its service life. Since the soft towel comes in various sizes, the operator can adjust the guiding plate according to the size of the soft towel. The operator rotates the adjusting screw, which causes the guiding plate to slide along the width of the soft towel. Through the linkage, the guiding plates can move closer and further apart. The adjusting screw has a self-locking effect and allows for precise adjustment, resulting in a reasonable structure.

[0017] Optionally, the linkage includes two linkage racks and a linkage gear. The two linkage racks correspond to two guide plates. The length direction of the linkage racks is parallel to the sliding direction of the guide plates. The linkage gear is rotatably connected to the frame. The two linkage racks are located on both sides of the linkage gear, and the linkage racks mesh with the linkage gear.

[0018] By adopting the above technical solution, when the operator rotates the adjusting screw, the adjusting screw drives the guide plate to move, the guide plate drives the corresponding linkage rack to move, the linkage rack drives the gear to move, and the linkage gear drives another linkage rack to move in the opposite direction. At this time, the two guide plates move in opposite directions, realizing the positioning and guidance of soft towels of different sizes. The linkage structure is simple and requires no additional operation to realize the relative movement of the two guide plates.

[0019] Optionally, an inclined plate is provided at one end of the guide plate away from the slicing mechanism, and the distance between the inclined plates on the two guide plates gradually decreases along the transport direction of the soft towel.

[0020] By adopting the above technical solution, the inclined plate makes it easier for workers to feed stacked soft towels into the space between the guide mechanisms without needing to accurately align them between the two guide plates. The inclined plate guides the towels smoothly into the space between the two guide plates.

[0021] Optionally, the inclined plate and the guide plate transition smoothly.

[0022] By adopting the above technical solution, the inclined plate and the guide plate transition smoothly, reducing the risk of the soft towel rubbing against the connection point and causing wrinkles, thus improving the quality of the soft towel.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The pressure plate and clamping spring are used to press the soft towel firmly before the slicing knife cuts it, so that the slicing knife can cut the soft towel neatly and reduce the burrs on the soft towel;

[0025] 2. The suction element is used to keep the soft towel moving with the conveyor belt at all times, reducing the displacement of the soft towel from the conveyor belt caused by inertial movement;

[0026] 3. The guiding mechanism is used to always feed the soft cloth to the same position of the slicing assembly, so that the slicing blade is subjected to uniform force and the service life of the slicing blade is extended. Attached Figure Description
