Technical Field
[0001] The utility model relates to the technical field of wet wipe production, in particular to a wet wipe edge trimming device for wet wipe production. Background Art
[0002] In the field of wet wipes production, with the continuous growth of market demand, the requirements for wet wipes production efficiency and product quality are becoming increasingly stringent. The traditional wet wipes trimming process often relies on relatively simple equipment or a large amount of manual operation. With the development of production technology, some simple mechanical trimming devices have begun to appear, but these devices have relatively single functions. Some trimming devices can only achieve basic cutting functions and lack pre-treatment of wet wipes, such as smoothing operations. As a result, the edges of the wet wipes are easily uneven due to wrinkles during cutting, resulting in a high scrap rate. In addition, these traditional mechanical devices are extremely inconvenient in replacing and maintaining the cutting blades, and often require professional technicians to spend a lot of time disassembling and installing them. Therefore, we have launched a new wet wipes trimming device for wet wipes production. Utility Model Content

[0008] By adopting the above technical solution, it can be ensured that the U-shaped frame moves along a specific trajectory during the movement, thereby playing a guiding role.
[0009] Preferably, the left portion of the outer surface of the bidirectional screw is rotatably connected to the inner left wall of the front fixing groove through a bearing, and the guide rod is fixed inside the rear fixing groove.
[0010] By adopting the above technical solution, the bidirectional screw can smoothly rotate around its own axis, and the bearing can effectively reduce the friction during the rotation process.
[0011] Preferably, the trimming mechanism and the U-shaped frame are fixedly connected together.
[0012] By adopting the above technical solution, the trimming mechanism can move synchronously with the movement of the U-shaped frame.
[0013] Preferably, the trimming mechanism includes a fixing frame, and a second telescopic cylinder is fixedly installed on the upper front and upper rear parts of the fixing frame, and the output ends of the two second telescopic cylinders are commonly provided with a mounting frame, and the front end of the mounting frame is provided with a T-shaped slot, and the interior of the T-shaped slot is movably connected to the cutting knife through a T-shaped block, and the right end of the mounting frame and the right end of the T-shaped block are both provided with four threaded holes, and the interiors of the two corresponding threaded holes are commonly provided with bolts.

[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] 1. The wet wipes are continuously transported to the device for processing via a conveyor belt. During the smoothing process, the controller precisely controls the two first telescopic cylinders to drive the U-shaped frame downward, allowing the smoothing and pressing rollers to quickly and accurately adhere to the wet wipes. Combined with the motor-driven rotation of the bidirectional screw and the guiding effect of the guide rod, the two H-shaped frames are forced to move away from each other, achieving efficient smoothing of the wet wipes to the left and right sides. This greatly improves processing efficiency and can smooth a large number of wet wipes in a short period of time, meeting the high-efficiency requirements of industrial production. The trimming mechanism can accurately move to the predetermined positions on the left and right sides of the wet wipes with the U-shaped frame. When trimming, the controller activates the four second telescopic cylinders on the left and right to drive the cutting knife downward for cutting, making the trimmed edges of the produced wet wipes neat and standardized, thereby improving product quality.
[0019] 2. The cutting knife is detachably connected to the T-slot through a T-block and bolts. When the cutting knife is worn or needs to be replaced with a cutting knife of different specifications according to different production requirements, the operator only needs to remove the four bolts on the corresponding side to easily remove the cutting knife from the T-slot. Then, the new cutting knife is inserted into the T-slot with a T-block and fixed with four bolts to complete the installation operation. The convenient disassembly and installation method greatly shortens the equipment maintenance time and reduces the difficulty of equipment maintenance, enables the equipment to quickly resume production, and improves the overall operation efficiency of the production equipment.

[0028] See also Figure 1-4 , the utility model provides a technical solution:
[0029] A wet wipe trimming device for wet wipe production comprises a cutting table 1, a mounting groove 2 is provided in the middle of the upper end of the cutting table 1, a conveyor belt 3 is provided inside the mounting groove 2, hydraulic cylinders 4 are provided at the four corners of the lower end of the cutting table 1, support legs 5 are fixedly installed at the lower ends of the four hydraulic cylinders 4, support pads 6 are provided at the lower ends of the four support legs 5, a mounting cover 7 is provided at the upper end of the cutting table 1, fixing grooves 8 are provided at the front and rear parts of the inner upper wall of the mounting cover 7, a smoothing and pressing device 9 is provided between the two fixing grooves 8, and a trimming mechanism 10 is provided on the facing surfaces of the two smoothing and pressing devices 9.
[0030] In this embodiment, the smoothing and pressing device 9 includes a guide rod 90 and a motor 91. A bidirectional screw rod 92 is fixedly installed at the output end of the motor 91. The left and right outer surfaces of the guide rod 90 and the bidirectional screw rod 92 are both movably installed with an H-shaped frame 93. The upper front and upper rear ends of the two H-shaped frames 93 are both fixedly installed with a first telescopic cylinder 94. The output ends of the two first telescopic cylinders 94 adjacent to each other are both provided with a U-shaped frame 95. A smoothing and pressing roller 96 is provided inside the two U-shaped frames 95. The front and rear ends of the two U-shaped frames 95 are both provided with a limiting block 97. The lower front end and the lower rear end of the two H-shaped frames 93 are both provided with a limiting groove 98; the U-shaped frame 95 is slidably installed inside the limiting groove 98 through the limiting block 97; the left outer surface of the bidirectional screw rod 92 is rotatably connected to the inner left wall of the front fixed groove 8 through a bearing, and the guide rod 90 is fixed inside the rear fixed groove 8.
[0031] Through the above scheme: when smoothing is required, by opening the two first telescopic cylinders 94 on the left and the right, the two smoothing pressing rollers 96 are driven to move downward and tightly adhere to the wet wipes below, and then the motor 91 is started, and its output end will drive the bidirectional screw rod 92 to rotate around its own axis. As the bidirectional screw rod 92 rotates, the two H-shaped frames 93 will move away from each other according to the rotation direction of the thread on the bidirectional screw rod 92 and the guidance of the guide rod 90, so as to facilitate the smoothing pressing rollers 96 to smooth the wet wipes to the left and right sides, and finally the smoothing pressing rollers 96 stay on the left and right sides of the wet wipes to press for subsequent operations.
[0032] In this embodiment, the trimming mechanism 10 is fixedly connected to the U-shaped frame 95; the trimming mechanism 10 includes a fixing frame 101, and the upper front and upper rear ends of the fixing frame 101 are both fixedly installed with a second telescopic cylinder 102, and the output ends of the two second telescopic cylinders 102 are commonly provided with a mounting frame 103, and the front end of the mounting frame 103 is provided with a T-shaped slot 104, and the inside of the T-shaped slot 104 is movably connected with a cutting knife 105 through a T-shaped block, and the right end of the mounting frame 103 and the right end of the T-shaped block are both provided with four threaded holes 106, wherein the insides of the two corresponding threaded holes 106 are commonly provided with bolts 107; the cutting knife 105 is detachably connected to the T-shaped slot 104 through the T-shaped block and the bolt 107.
[0033] Through the above scheme: the two trimming mechanisms 10 move to the left and right sides of the wet wipes along with the U-shaped frame 95. When trimming is required, the four left and right second telescopic cylinders 102 are opened by the controller, so as to facilitate the two cutting knives 105 to move downward for cutting. During cutting, the two cutting knives 105 are located at the upper left and right parts of the cutting table 1, so that the conveyor belt 3 will not be damaged during cutting. When the corresponding cutting knife 105 needs to be disassembled, the cutting knife 105 can be taken out of the T-shaped slot 104 by disassembling the four bolts 107 on the corresponding side, which is convenient for quick disassembly. Then the new cutting knife 105 is clamped in the T-shaped slot 104 through the T-shaped block and fixed with four bolts 107, which can be installed, which is convenient for quick installation and disassembly and easy to operate.
[0034] It should be noted that the present invention is a wet wipe trimming device for wet wipe production. During use, after the wet wipes are conveyed to the bottom of the smoothing and pressing device 9 by the conveyor belt 3, the two first telescopic cylinders 94 are turned on by the controller. The output ends of the two first telescopic cylinders 94 drive the U-shaped frame 95 to move downward, so that the smoothing and pressing rollers 96 are close to the wet wipes below. By starting the motor 91, the motor 91 drives the bidirectional screw rod 92 to rotate. According to the thread rotation direction of the bidirectional screw rod 92 and the guiding effect of the guide rod 90, the two H-shaped frames 93 move away from each other, and then the wet wipes are smoothed to the left and right sides by the smoothing and pressing rollers 96. Finally, the smoothing and pressing rollers 96 stop on the left and right sides of the wet wipes to press, in preparation for subsequent trimming. The trimming mechanism 10 moves to the left and right sides of the wet wipes with the U-shaped frame 95. When trimming, the controller turns on the four second telescopic cylinders 102 on the left and right, driving the two cutting knives 105 to move downward for cutting. Because the cutting blade 105 is located at the left and right parts of the upper end of the cutting table 1, it will not damage the conveyor belt 3. When the cutting blade 105 needs to be replaced, the four bolts 107 on the corresponding side are removed, the cutting blade 105 is taken out from the T-shaped slot 104, and the new cutting blade 105 is inserted into the T-shaped slot 104 with a T-shaped block, and then fixed with four bolts 107 to complete the installation and removal operations.
