Description

Technical Field

[0001] This utility model relates to the field of cotton towel processing equipment, specifically a transverse slitting device for spunlace cotton towels. Background Technology

[0002] Spunlace cotton towels are nonwoven products made from natural cotton fibers or viscose fibers through a high-pressure spunlace nonwoven process. The high-pressure micro-water jets cause the fibers to entangle without the need for chemical adhesives, forming a soft and strong fiber web structure. Medical-grade products also undergo high-pressure steam sterilization.

[0003] In the existing technology, CN215051558U describes a transverse slitting device for spunlace cotton towels, belonging to the field of mechanical technology. It includes a main structure with supports at both ends of its bottom. Support rods are mounted on the top of each support, and a support rod is mounted on one side of each pair of adjacent support rods. Multiple sets of electrically operated telescopic rods are evenly installed at the bottom of the support rods. This invention uses a sleeve rod, under the elastic potential energy of an elastic element, to push a pressure plate to support the top of a guide roller and to compress and support the spunlace cotton towel on the surface of the guide roller. When the spunlace cotton towel moves under force, it generates a pushing force on a rolling ball, causing the ball to roll inside the rolling groove under the dynamic action of the spunlace cotton towel. The notch provides sufficient space for the cutter to cut, while simultaneously providing stable support for the cut edge of the spunlace cotton towel, preventing it from fraying due to the cutting force, resulting in a neater slitting edge for the spunlace cotton towel.

[0004] Existing transverse slitting devices for spunlace cotton towels require bolts or other fixing methods to secure the slitting device to the machine body during use. However, this makes disassembly and maintenance of the slitting device extremely inconvenient after it is fixed. Therefore, a transverse slitting device for spunlace cotton towels is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, such as the inconvenience of disassembling common slitting devices after installation on the machine body, this utility model proposes a transverse slitting device for spunlace cotton towels.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a transverse slitting device for spunlace cotton towels, including an assembly base, a fixing bolt rotatably connected to the inner surface wall of the assembly base, an insertion block slidably connected to the inner surface wall of the assembly base, a fixing body fixedly connected to the top of the assembly base, an adjusting screw threadedly connected to the inner surface wall of the fixing body, a knob fixedly connected to one end of the adjusting screw, a limit block rotatably connected to the other end of the adjusting screw, a limit block slidably connected to the inner surface wall of the fixing body, one end of the limit block being inserted into one side of the insertion block, and a support frame fixedly connected to the top of the insertion block.

[0007] Preferably, a sliding track frame is fixedly connected to the top of the support frame. The inner surface of the sliding track frame is provided with a sliding groove. A servo motor is installed on the side of the sliding track frame. A guide screw is fixedly connected to the output end of the servo motor. The guide screw is rotatably connected to the inner surface of the sliding track frame.

[0008] Preferably, the outer wall of the guide screw is threadedly connected to a guide slider, the guide slider is slidably connected to the inner wall of the sliding track frame, a hydraulic device is installed at the bottom of the guide slider, and a limit groove is formed on the inner wall of the guide slider.

[0009] Preferably, a fixing block is fixedly connected to the output end of the hydraulic device, and the fixing block is fixedly connected to a limit rod via a guide slider.

[0010] Preferably, the bottom of the fixing block is fixedly connected to the abutting main block, and the inner surface of the abutting main block is fixedly connected to the telescopic rod.

[0011] Preferably, the output end of the telescopic rod is fixedly connected to an inner slider, and the inner slider is fixedly connected to an abutting spring through an abutting main block.

[0012] Preferably, a transmission gear is rotatably connected to one side of the inner slider, and a track meshes with the outer wall of the transmission gear.

[0013] Preferably, a blade holder is fixedly connected to the bottom of the fixing block, and a metal blade is fixedly connected to the bottom of the blade holder.

[0014] The advantages of this utility model are:

[0015] This utility model achieves the effect of separating the assembly base and the plug-in block by setting a separate design and using a fixed body and a limiting block for limiting and fixing. This allows the plug-in block and the cutting device to still be separated after the assembly base is limited and fixed, solving the common problem that the cutting device is inconvenient to disassemble when installed on the machine body.

[0016] This invention uses a track and transmission gear, along with an inner slider and a stop spring, to allow the track to stop at the top of the soft towel, thus limiting the cutting area of ​​the soft towel and solving the problem of wrinkles forming during the cutting process.

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

[0024] This application discloses a transverse slitting device for spunlace cotton towels.

[0025] Reference Figures 1-5A transverse slitting device for spunlace cotton towels includes an assembly base 1. A fixing bolt 2 is rotatably connected to the inner wall of the assembly base 1. A plug-in block 3 is slidably connected to the inner wall of the assembly base 1. A fixing body 23 is fixedly connected to the top of the assembly base 1. An adjusting screw 24 is threadedly connected to the inner wall of the fixing body 23. A knob 25 is fixedly connected to one end of the adjusting screw 24, and a limiting block 14 is rotatably connected to the other end of the adjusting screw 24. The limiting block 14 is slidably connected to the inner wall of the fixing body 23. One end of the limiting block 14 is inserted into one side of the plug-in block 3. A support frame is fixedly connected to the top of the plug-in block 3. The device works by separating the assembly base 1 and the plug-in block 3. The design utilizes a limiting block for positioning, allowing the insert block 3, which is slidably connected to the assembly base 1, to slide freely out of the assembly base 1. When the knob 25 is rotated, the adjusting screw 24 rotates and moves along the inner surface of the fixed body 23. Simultaneously, because the limiting block 14 is rotatably connected to the adjusting screw 24, the limiting block 14 moves inside the fixed body 23 and engages with one side of the insert block 3 for positioning. When the limiting block 14 positions the insert block 3, it can fix the cutting device. When the limiting block 14 no longer positions the insert block 3, the insert block 3 can be separated from the assembly base 1, facilitating the separation of the cutting device.

[0026] Reference Figure 1 and Figure 2 A sliding track frame 5 is fixedly connected to the top of the support frame 4. A sliding groove 7 is provided on the inner surface of the sliding track frame 5. A servo motor 6 is installed on the side of the sliding track frame 5. A guide screw 8 is fixedly connected to the output end of the servo motor 6. The guide screw 8 is rotatably connected to the inner surface of the sliding track frame 5. Through the setting of the servo motor 6 and the guide screw 8, the servo motor 6 can drive the guide screw 8 to rotate on the inner surface of the sliding track frame 5. The design of the sliding track frame 5 can play the role of guiding the cutting.

[0027] Reference Figure 2 and Figure 3 The outer wall of the guide screw 8 is threadedly connected to the guide slider 9, which is slidably connected to the inner wall of the sliding track frame 5. A hydraulic device 10 is installed at the bottom of the guide slider 9, and a limit groove 15 is opened on the inner wall of the guide slider 9. Through the setting of the guide slider 9, the guide screw 8 can rotate, and because the guide slider 9 is threadedly connected to the guide screw 8, the guide slider 9 can move within the sliding track frame 5 in a limited position.

[0028] Reference Figure 3 and Figure 4The output end of the hydraulic device 10 is fixedly connected to a fixing block 12. The fixing block 12 is fixedly connected to a limit rod 11 through a guide slider 9. By cooperating with the fixing block 12, the hydraulic device 10 can cause the guide slider 9 to descend as a whole after it is started, and the limit rod 11 can be used for limiting.

[0029] Reference Figure 3 and Figure 4 The bottom of the fixed block 12 is fixedly connected to the abutting main block 13, and the inner surface wall of the abutting main block 13 is fixedly connected to the telescopic rod 19. The telescopic rod 19 can be freely extended and retracted. At the same time, the descent of the fixed block 12 will synchronously drive the abutting main block 13 to descend.

[0030] Reference Figure 3 and Figure 4 The output end of the telescopic rod 19 is fixedly connected to an inner slider 21. The inner slider 21 is fixedly connected to an abutting spring 20 via an abutting main block 13. The telescopic rod 19 is set in conjunction with the abutting spring 20 so that the descent of the abutting main block 13 will cause the inner slider 21 to slide inside the abutting main block 13. At the same time, the telescopic rod 19 is in a contracted state, and the abutting spring 20 will be compressed by force.

[0031] Reference Figure 3 and Figure 4 A transmission gear 22 is rotatably connected to one side of the inner slider 21. The outer wall of the transmission gear 22 meshes with the track 18. Through the meshing of the transmission gear 22 and the track 18, the track 18 can still move freely after it abuts against the soft towel. With the above structure, the pressure provided by the abutment spring 20 to the track 18 after compression is within 15N, thereby achieving abutment limit while also fixing the soft towel.

[0032] Reference Figure 2 and Figure 3 The bottom of the fixing block 12 is fixedly connected to the blade holder 16, and the bottom of the blade holder 16 is fixedly connected to the metal blade 17. By setting the metal blade 17, the blade holder 16 can be lowered as a whole, and the soft towel can be cut by the metal blade 17.

[0033] Working Principle: The separation design of the assembly base 1 and the plug-in block 3, along with the use of limiting blocks for positioning, allows the plug-in block 3, which is slidably connected to the assembly base 1, to slide freely out of the assembly base 1. Rotating the knob 25 causes the adjusting screw 24 to rotate and move threadedly along the inner surface of the fixed body 23. Simultaneously, because the limiting block 14 is rotatably connected to the adjusting screw 24, it moves within the fixed body 23 and engages with one side of the plug-in block 3 for positioning. When the limiting block 14 positions the plug-in block 3, it secures the cutting device. When the limiting block 14 no longer positions the plug-in block 3, it allows the plug-in block 3 to separate from the assembly base 1, facilitating the separation of the cutting device. The servo motor 6 drives the guide screw 8 to rotate along the inner surface of the sliding track frame 5. The sliding track frame 5 guides the cutting process. The guide slider 9 further guides the rotation of the guide screw 8. Furthermore, because the guide slider 9 is threadedly connected to the guide screw 8, the guide slider 9 can move within the sliding track frame 5. With the hydraulic actuator 10 and the fixing block 12 in place, the hydraulic actuator 10, when activated, allows the guide slider 9 to descend as a whole. Simultaneously, the limiting rod 11 provides a limiting position. With the telescopic rod 19 and the abutment spring 20 in place, the descent of the abutment block 13 causes the inner slider 21 to slide within the abutment block 13. At the same time, the telescopic rod 19 is in a retracted state, and the abutment spring 20 is compressed. Through the engagement of the transmission gear 22 and the track 18, the track 18 can still move freely after abutting against the soft towel. With the above structure, the pressure provided by the compressed abutment spring 20 to the track 18 is within 15N, thus achieving both abutment limitation and fixation of the soft towel. With the metal blade 17 in place, after the blade holder 16 descends as a whole, the metal blade 17 can be used to cut the soft towel.

[0034] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
