Description

Technical Field

[0001] This utility model relates to the technical field of wet wipe production equipment, specifically to a cutting device for wet wipe processing. Background Technology

[0002] Wet wipes are widely used in personal care, household cleaning, and medical hygiene due to their portability and ease of use. During the production process, edge-cutting equipment is used to cut the wipes to ensure they are sized correctly and have neat edges.

[0003] Because wet wipes are made of soft material, they are prone to deviation during conveying and cutting. This deviation leads to uneven cutting lines and even incomplete cuts, affecting the quality of the finished product. Existing edge-cutting equipment uses pressure rollers to compress the wet wipes during transport, but these rollers only act at the conveyor belt input end. The cutting area lacks a dynamic clamping device to stabilize the position of the wet wipes. At the moment of blade cutting, the wet wipes may shift or wrinkle due to uneven force, resulting in uneven cut edges and even dimensional deviations, affecting subsequent packaging and use. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a cutting device for processing wet wipes, so as 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 cutting device for processing wet wipes includes support plates arranged opposite each other, a cutting table between the support plates, a conveyor belt located behind the cutting table between the support plates, a cutting groove on the cutting table, a movable support frame above the cutting groove, a rotating disc cutter extending into the cutting groove on the support frame, lifting pressure plates on both sides of the cutting groove, a lifting assembly for driving the pressure plates to rise and fall on the cutting table, a movable L-shaped limiting plate opposite to the side of the cutting table away from the conveyor belt, and a moving assembly for driving the L-shaped limiting plate to move above the cutting table.

[0007] Furthermore, the lifting assembly includes vertical blocks positioned opposite each other on both sides of the cutting groove. Each vertical block has a circular cavity with an open bottom. A push rod extends through the cutting table and into the circular cavity below the cutting table. A spring for pushing the push rod downward is provided inside the circular cavity. A displacement groove communicating with the circular cavity is opened on the side of the vertical block. Both ends of the pressure plate extend into the displacement groove and are connected to the outer wall of the push rod.

[0008] Furthermore, there are rotating rods located below the top rods between the support plates, and a rotating disk is provided on the rotating rods corresponding to the top rods. Multiple arc-shaped grooves are evenly spaced along the circumference on the rotating disks.

[0009] Furthermore, one end of the rotating rod extends from the support plate, and the end of the rotating rod extending from the support plate is provided with a sprocket. A chain is provided between the sprockets, and a first motor for driving the rotating rod to rotate is provided on the support plate.

[0010] Furthermore, the movable component includes a mounting bracket disposed between the support plates, a round rod disposed on the mounting bracket, a movable block disposed opposite to the round rod, a connecting rod connected to the lower end of the movable block and an L-shaped limiting plate, and a turntable disposed on the round rod for driving the round rod to rotate.

[0011] Furthermore, the mounting bracket has a groove, and the round rod has a locking disc at the groove. The pressure plate near the mounting bracket has a bent rod that extends into the groove, and the bent rod in the groove has an annular surface that can fit with the locking disc.

[0012] Furthermore, an installation frame is provided above the cutting groove, a sliding block is provided inside the installation frame, a lead screw is provided on the installation frame and threadedly connected to the sliding block, a second motor is provided on the installation frame for driving the lead screw to rotate, a moving groove is provided at the bottom of the installation frame, the upper end of the support frame extends into the installation frame through the moving groove and is connected to the sliding block, and a third motor is provided on the support frame for driving the disc cutter to rotate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, when the wet wipe is conveyed to the cutting table to be cut, the pressure plates on both sides of the cutting groove can be lowered under the drive of the lifting component to press the wet wipe on both sides of the cutting groove. The rotating disc cutter driven by the support frame moves laterally along the cutting groove to cut the wet wipe into segments, preventing the wet wipe from moving when the cutting blade cuts it, which would cause the cutting edge to be uneven or the size deviation to occur.

[0015] 2. In this utility model, the L-shaped limiting plate is driven to move by the moving component, so that the L-shaped moving plate is moved to a position that matches the width of the wet wipe, so that the wet wipe passes between the L-shaped limiting plates and is limited to prevent the wet wipe from deviating on the cutting table and causing the cutting position to be uneven.

Detailed Implementation

[0022] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0023] The following is in conjunction with the appendix Figures 1-5 This embodiment will be described in further detail.

[0024] Please see Figures 1-5 This embodiment of a wet wipe processing edge-cutting device includes support plates 100 arranged opposite each other, a cutting table 101 between the support plates 100, a conveyor belt 102 located behind the cutting table 101 between the support plates 100, a cutting groove 103 on the cutting table 101, a movable support frame 104 above the cutting groove 103, a disc cutter 105 extending into the cutting groove 103 and capable of rotation on the support frame 104, lifting pressure plates 106 on both sides of the cutting groove 103, a lifting assembly for driving the pressure plates 106 to rise and fall on the cutting table 101, a movable L-shaped limiting plate 107 opposite to the side of the cutting table 101 away from the conveyor belt 102, and a moving assembly for driving the L-shaped limiting plate 107 to move above the cutting table 101.

[0025] In this embodiment, the cutting table 101 is fixedly connected between the support plates 100. When the wet wipe is conveyed to the position to be cut on the cutting table 101, the pressure plates 106 located on both sides of the cutting groove 103 can be lowered under the drive of the lifting component to press the wet wipe on both sides of the cutting groove 103. The rotating disc cutter 105 driven by the support frame 104 can move laterally along the cutting groove 103 to cut the wet wipe into segments, preventing the wet wipe from moving when the cutting blade cuts the wet wipe, which would cause the cutting edge to be uneven or the size deviation to occur.

[0026] In this embodiment, during the cutting of the wet wipes, one side of the wet wipes is located on the conveyor belt 102, so that the cut wet wipes can be transported along the conveyor belt 102 for further processing.

[0027] In this embodiment, the L-shaped limiting plate 107 is moved by the moving component, so that the L-shaped moving plate is moved to a position that matches the width of the wet wipe, so that the wet wipe passes between the L-shaped limiting plates and is limited to prevent the wet wipe from running off-center on the cutting table 101, resulting in an uneven cutting position.

[0028] Please see Figures 1-5 In this embodiment, the lifting assembly includes vertical blocks 200 disposed on both sides of the cutting groove 103. The vertical blocks 200 have a circular cavity with an open bottom. A top rod 201 is provided below the cutting table 101, penetrating the cutting table 101 and extending into the circular cavity. A spring 202 is provided in the circular cavity to push the top rod 201 downward. A displacement groove 203 communicating with the circular cavity is provided on the side of the vertical blocks 200. Both ends of the pressure plate 106 extend into the displacement groove 203 and are connected to the outer wall of the top rod 201.

[0029] In this embodiment, the vertical block 200 is fixedly connected to the cutting table 101 on both sides of the cutting groove 103. The top rod 201 is slidably arranged in the circular cavity. The two ends of the pressure plate 106 are fixedly connected to the top rod 201. The pressure plate 106 is slidably arranged between the pressure plate 106 and the displacement groove 203. The top rod 201 is pushed down by the spring 202, which can drive the pressure plate 106 to move down to press the wet wipe.

[0030] Please see Figures 1-5 In this embodiment, a rotating rod 204 located below the top rod 201 is provided between the support plates 100. A rotating disk 205 is provided on the rotating rod 204 corresponding to the top rod 201. A plurality of arc-shaped grooves 206 are evenly spaced along the circumferential direction on the rotating disk 205.

[0031] In this embodiment, the rotating rod 204 is mounted on the support plate 100 via bearings, and the rotating disk 205 is fixedly connected to the rotating rod 204. The rotating rod 204 drives the rotating disk 205 to rotate, so that the bottom end of the top rod 201 can reciprocate between the arc-shaped groove 206 and the outer wall of the rotating disk 205. When the bottom end of the top rod 201 extends into the arc-shaped groove 206, the spring 202 pushes the pressure plate 106 downward to press the wet wipe. When the bottom end of the top rod 201 moves from the arc-shaped groove 206 to the outer wall of the rotating disk 205, the top rod 201 moves upward, driving the pressure plate 106 upward, releasing the pressure on the wet wipe, so that the cut wet wipe can be conveyed by the conveyor belt.

[0032] Please see Figures 1-5 In this embodiment, one end of the rotating rod 204 extends out from the support plate 100, and the end of the rotating rod 204 extending out from the support plate 100 is provided with a sprocket 300. A chain 301 is provided between the sprockets 300, and a first motor 302 for driving the rotating rod 204 to rotate is provided on the support plate 100.

[0033] In this embodiment, a rotating rod 204 is driven to rotate by the first motor 302. With the arrangement of the sprocket 300 and the chain 301, the rotating rods 204 arranged opposite each other can rotate synchronously, so as to simultaneously control the pressure plates 106 on both sides of the cutting groove 103 to rise and fall at the same time.

[0034] Please see Figures 1-5 In this embodiment, the movable component includes a mounting frame 400 disposed between the support plates 100. The mounting frame 400 is provided with a round rod 401. A movable moving block 402 is provided opposite to the round rod 401. The lower end of the moving block 402 is provided with a connecting rod 403 connected to the L-shaped limiting plate 107. The round rod 401 is provided with a turntable 404 for driving the round rod 401 to rotate.

[0035] In this embodiment, the mounting frame 400 is fixedly connected to the support plate 100. The round rod 401 is mounted on the mounting frame 400 through a bearing. The round rod 401 is provided with a bidirectional thread. The moving block 402 is threadedly connected to the round rod 401. The upper end of the connecting rod 403 is fixedly connected to the moving block 402, and the lower end is fixedly connected to the L-shaped limiting plate 107. The turntable 404 is fixedly connected to the round rod 401. The turntable 404 drives the round rod 401 to rotate, which can drive the moving blocks 402 to move closer or further away from each other, thereby driving the L-shaped limiting plate 107 to move closer or further away from each other, so as to limit the wet wipes according to the width of the wet wipes and prevent the wet wipes from deviating.

[0036] Please see Figures 1-5In this embodiment, the mounting bracket 400 is provided with a groove 405, and the round rod 401 is provided with a locking disc 406 corresponding to the groove 405. The pressure plate 106 near the mounting bracket 400 is provided with a bent rod 407 that extends into the groove 405. The bent rod 407 located in the groove 405 is provided with an annular surface 408 that can fit with the locking disc 406.

[0037] In this embodiment, the locking disc 406 is fixedly connected to the round rod 401, and the bent rod 407 is fixedly connected to the pressure plate 106. Friction pads are provided on the outer wall and the annular surface 408 of the locking disc 406. When the pressure plate 106 presses the wet wipe for cutting, the pressure plate 106 can drive the annular surface 408 to press the outer wall of the locking disc 406, locking the round rod 401 and preventing the round rod 401 from rotating due to accidental rotation of the turntable 404 during cutting. This would cause the L-shaped limiting plate 107 to shift, preventing the L-shaped limiting plate 107 from limiting the wet wipe and causing the wet wipe to deviate, resulting in an uneven cutting position.

[0038] Please see Figures 1-5 In this embodiment, a mounting frame 108 is provided above the cutting groove 103, a sliding block 109 is provided inside the mounting frame 108, a lead screw 110 is provided on the mounting frame 108 and threadedly connected to the sliding block 109, a second motor 111 for driving the lead screw 110 to rotate is provided on the mounting frame 108, a moving groove is provided at the bottom of the mounting frame 108, the upper end of the support frame 104 extends into the mounting frame 108 through the moving groove and is connected to the sliding block 109, and a third motor for driving the disc cutter 105 to rotate is provided on the support frame 104.

[0039] In this embodiment, the support plate 100 is provided with a support column for supporting the mounting frame 108. The sliding block 109 is slidably disposed in the mounting frame 108. The support frame 104 is fixedly connected to the sliding block 109. The second motor 111 drives the lead screw 110 to rotate, which can drive the sliding block 109 to move, thereby driving the disc cutter 105 to move laterally to cut the wet wipes. The third motor is used to drive the disc cutter 105 to rotate to cut the wet wipes.

[0040] In use, this invention adjusts the spacing of the L-shaped limiting plates 107 according to the width of the wet wipes, allowing the wet wipes conveyed to the cutting table 101 to pass between the L-shaped limiting plates 107, thus limiting the wet wipes and preventing them from deviating on the cutting table 101. When cutting the wet wipes, the first motor 302 drives the rotating disk 205 to rotate, and the spring 202 drives the top rod 201 to descend, causing the pressure plate 106 to move down and press the two sides of the wet wipes. Then, the second motor 111 drives the rotating cutting blade to move laterally along the cutting groove 103 to cut the wet wipes, avoiding the wet wipes from deviating during cutting and causing uneven cutting. After cutting, the first motor 302 continues to drive the rotating disk 205 to rotate, causing the top rod 201 to move up. The upward movement of the top rod 201 causes the pressure plate 106 to move up, releasing the pressure on the wet wipes, allowing the cut wet wipes to move with the conveyor belt 102 for the next processing step.

[0041] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
