Description

Technical Field

[0001] This utility model relates to the field of wet wipe production technology, specifically a cutting tool for wet wipe production. Background Technology

[0002] Paper towels are everyday cleaning products made from ingredients such as pure water, spunlace nonwoven fabric, and propylene glycol. They are widely used for wiping the face, hands, or cleaning the skin. Their softness and high absorbency make them an essential item in household and personal care. In the production process of wet wipes, to ensure that each wipe can be used individually and maintains hygiene, it must be precisely cut. This process is usually completed at a specific station on the wet wipe production line, where specialized equipment cuts the continuously produced wet wipe material to predetermined dimensions.

[0003] In existing technology, during the cutting process of wet wipes, the uncut wet wipe material moves laterally from one side to the other on the cutting table, a process driven by a traction device. When the wet wipe reaches the preset cutting position, the traction device stops working, and then the cylinder drives the cutter to move rapidly downwards, achieving a quick cut of the wet wipe. To ensure a good cutting effect, a certain downward movement is usually set at the cut to allow the cutter to completely penetrate the material. For example, Chinese patent CN202223486141.8 discloses an automatic cutting and receiving device, which includes a first cutting component and a second cutting component. Each component includes a support platform, a first driving cylinder located on the upper side of the support platform, a pressing block connected to the output end of the first driving cylinder, and a second driving cylinder located on the periphery of the support platform near the channel side, along with a cutter at its output end. This design relies on the coordinated action of two cylinders: one is responsible for pressing the wet wipe material, while the other performs the actual cutting action.

[0004] However, while the aforementioned cutting methods can meet production needs to some extent, existing technologies still have some significant limitations. First, the need for two independent cylinders to perform the pressing and cutting tasks separately complicates the entire process, increasing equipment costs and maintenance difficulty. Second, the dual-cylinder operation mode is prone to synchronization problems, affecting cutting accuracy and efficiency. Furthermore, traditional cutting devices lack effective buffering mechanisms, failing to adequately absorb the impact force generated during cutting. This can not only lead to uneven edges on the wet paper towels but also accelerate blade wear, shortening their lifespan. Utility Model Content

[0005] The purpose of this invention is to provide a cutting tool for producing wet paper towels, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cutting tool for producing wet wipes, comprising: a support frame, a cylinder fixedly installed in the middle of the support frame, a connecting block fixedly connected to the output end of the cylinder, the bottom of the connecting block fixedly connected to the cutter, and arc-shaped pressure plates provided on both sides of the cutter, the bottom of the arc-shaped pressure plates being lower than the bottom of the cutter.

[0007] The top of the curved pressure plate is fixedly connected to the T-block. The top of the T-block is fixedly connected to the connecting frame via a large spring. A guide post is fixedly connected to the top of the connecting frame. The top of the guide post is slidably fitted inside the support frame. A buffer assembly is provided between the connecting block and the connecting frame.

[0008] Preferably, the support frame has mounting holes at both ends of the bottom and limit holes on both sides of the top surface of the support frame, and the limit holes are slidably connected to the guide column.

[0009] Preferably, guide blocks are fixedly connected to the two inner side walls of the top of the support frame, and guide columns are sleeved inside the guide blocks and slidably connected to the guide blocks.

[0010] Preferably, a guide strip is fixedly connected inside the connecting frame, and guide grooves are opened on both sides of the T-block, with the guide strip and the guide grooves being slidably connected.

[0011] Preferably, the connecting block and the cutter are fixedly connected by the cooperation of angle steel and bolts, and the bottom blade of the cutter is 0.2-5cm higher than the bottom arc surface of the arc pressure plate.

[0012] Preferably, the buffer assembly includes a connecting rod, one end of which is fixedly connected to the connecting block, and the other end of which is slidably sleeved on the limiting rod.

[0013] Preferably, both ends of the limiting rod are fixedly connected to the connecting frame, and a buffer spring is fixedly installed between the end of the connecting rod near the connecting frame and the connecting frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. Through the coordinated action of the support frame, cylinder, and buffer assembly, the cutter is ensured to move smoothly and accurately during the cutting process. The buffer assembly between the connecting block and the connecting frame effectively improves the stability of the entire motion system, allowing the cutter to cut into the material more gently when it comes into contact with the wet paper towel, reducing deviation or deformation caused by sudden pressure, and ensuring consistency and accuracy in every cut.

[0016] 2. The buffer spring absorbs the impact force generated during the cutting process, reducing direct collision and wear between the cutter and the wet paper towel material. This design not only protects the blade but also reduces maintenance costs and ensures long-term stable operation.

[0017] 3. The curved pressure plate pre-presses the wet paper towel before the cutter, preventing it from shifting or wrinkling during cutting, thus improving the cutting effect. At the same time, the curved pressure plate design reduces adhesion between the wet paper towel and the plate, making it easier for the paper towel to detach and further ensuring neat and aesthetically pleasing edges after cutting.

[0018] 4. The cutting blade for this wet wipe production does not require a separate cylinder to connect to the curved pressure block to press the wet wipe for cutting. Instead, the same cylinder drives both the cutter and the pressure plate to press the wet wipe, simplifying the cutting process. Attached Figure Description

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Example 1: Please refer to Figure 1 - Figure 4This utility model provides a technical solution: a cutting tool for producing wet wipes, comprising: a support frame 1, which provides stable support for the entire device; a cylinder 2 fixedly installed in the middle of the support frame 1, the cylinder 2 being located on the top side of the middle of the support frame 1 and electrically connected to an external terminal control device; a connecting block 3 fixedly connected to the output end of the cylinder 2; the bottom of the connecting block 3 fixedly connected to a cutter 4; arc-shaped pressure plates 5 provided on both sides of the cutter 4, the bottom of the arc-shaped pressure plates 5 being lower than the bottom of the cutter 4; the side of the cutter 4 being slidably connected to the side of the arc-shaped pressure plates 5; the top of the arc-shaped pressure plates 5 being fixedly connected to a T-shaped block 6; the lower surface of the T-shaped block 6 abutting against the cutter 4; the top of the T-shaped block 6 being fixedly connected to a connecting frame 8 via a large spring 7; a guide post 9 fixedly connected to the top of the connecting frame 8; the top of the guide post 9 being slidably fitted inside the support frame 1; and a buffer assembly 10 provided between the connecting block 3 and the connecting frame 8.

[0026] This wet wipe cutting blade is used on a wet wipe production line. It is mounted on both sides of the cutting line via a support frame 1. By extending the output end of a control cylinder 2, the cylinder 2 drives the connecting block 3 downwards. The downward movement of the connecting block 3 allows the cutter 4 to cut the wet wipe. Simultaneously, a buffer assembly 10 installed between the connecting block 3 and the connecting frame 8 provides cushioning during cutting, allowing the blade to cut more gently into the material when it contacts the wet wipe. This reduces deviation or deformation caused by sudden pressure, ensuring consistency and accuracy in each cut and extending the blade's lifespan. Before the cutter 4 falls onto the wet wipe, the lower surface of the curved pressure plate 5 is lower than the bottom of the cutter 4. During the cutting process, the curved pressure plates 5 on both sides pre-press the wet paper towel. As the cutter 4 continues to move downward, the curved pressure plates 5 are connected to the connecting frame 8 by the T-block 6, which compresses the large spring 7, thereby improving the cutting quality. At the same time, the guide column 9, which is fixedly connected to the connecting frame 8, slides in the support frame 1, improving stability. During the cutting process, the bottom of the cutter 4 is lower than the lower surface of the curved pressure plate 5. In the cutting line, the wet paper towel production cutting tool does not need to be equipped with a separate cylinder 2 for connecting and pressing the wet paper towel for cutting. Instead, the same cylinder 2 drives both the cutter 4 and the curved pressure plate 5 to press the wet paper towel, simplifying the cutting process.

[0027] Example 2: Based on Example 1, mounting holes 11 are provided at both ends of the bottom of the support frame 1. The mounting holes 11 facilitate the fixed installation of the support frame 1. Limiting holes 12 are provided on both sides of the top upper surface of the support frame 1. The limiting holes 12 are slidably connected to the guide post 9. The limiting holes 12 limit the guide post 9. Guide blocks 13 are fixedly connected to the two inner side walls of the top of the support frame 1. The guide blocks 13 further limit the guide post 9. The guide post 9 is sleeved in the guide block 13 and slidably connected to the guide block 13. A guide strip 14 is fixedly connected inside the connecting frame 8. Guide grooves 15 are provided on both sides of the T-block 6. The guide strip 14 is slidably connected to the guide groove 15. The sliding connection between the guide groove 15 and the guide strip 14 improves the stability of the movement of the T-block 6, thereby improving the stability of the movement of the arc-shaped pressure plate 5. The connecting block 3 and the cutter 4 are fixedly connected by the cooperation of angle steel 16 and bolts. The bottom blade of the cutter 4 is 0.5-2cm higher than the bottom arc surface of the arc-shaped pressure plate 5.

[0028] Before the cutter 4 falls onto the wet paper towel, the blade of the cutter 4 is 0.5-2cm higher than the lower surface of the curved pressure plate 5, so the curved pressure plate 5 will pre-contact the wet paper towel. As the cutter 4 continues to move down, the curved pressure plate 5, connected by the T-block 6, is limited by the guide strip 14 and guide groove 15 in the connecting frame 8, causing the T-block 6 to squeeze the large spring 7, thus compressing the large spring 7. In addition, the guide block 13 and the support frame 1 guide the guide column 9, thereby improving the stability of vertical movement. This allows the curved surface at the bottom of the curved pressure plate 5 to pre-press the wet paper towel, preventing the wet paper towel from moving during the cutting process. The pressed wet paper towel is also less prone to wrinkling, improving the cutting effect. Furthermore, the curved surface at the bottom of the curved pressure plate 5 can reduce the adhesion between the wet paper towel and the curved pressure plate 5, making it easier for the wet paper towel to separate from the curved pressure plate 5.

[0029] Example 3: Based on Example 2, the buffer assembly 10 includes a connecting rod 17. There are two connecting rods 17 arranged symmetrically about the central plane of the connecting block 3. One end of the connecting rod 17 is fixedly connected to the connecting block 3, and the other end of the connecting rod 17 is slidably sleeved on the limiting rod 18. The limiting rod 18 guides and limits the connecting rod 17, thereby improving the stability of the movement of the connecting block 3 and thus improving the stability of the cutter 4. Both ends of the limiting rod 18 are fixedly connected to the connecting frame 8. A buffer spring 19 is fixedly installed between the end of the connecting rod 17 near the connecting frame 8 and the connecting frame 8.

[0030] By incorporating two symmetrically arranged connecting rods 17 in conjunction with the limiting rod 18, this design effectively improves the stability of the connecting block 3 during movement, thereby making the cutter 4 more stable and precise during cutting, significantly enhancing cutting accuracy and the dimensional consistency of each wet tissue. Simultaneously, the buffer spring 19 absorbs the impact force generated during cutting, reducing direct collisions and wear between the cutter 4 and the wet tissue material, extending the tool's lifespan and reducing maintenance costs. Furthermore, the guiding and limiting design of the connecting rods 17 and the limiting rod 18 ensures the smoothness of the cutting process, preventing tearing or unevenness at the edges of the wet tissue, and guaranteeing neat and aesthetically pleasing edges for each wet tissue.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
