Description

Technical Field

[0001] This utility model relates to the field of tissue paper production technology, and in particular to a slitting device for the production and processing of cotton soft towels. Background Technology

[0002] Cotton soft towels, a type of nonwoven fabric product made from fibers such as cotton and viscose through nonwoven processes like spunlace, have become a new environmentally friendly alternative to paper towels, cotton pads, and face towels due to their softness, excellent absorbency, and lint-free properties. They are widely used for daily cleaning and care of adults and infants. In the production and processing of cotton soft towels, slitting is a crucial step, requiring the cutting of large rolls of cotton soft towels into dry towels of specific sizes.

[0003] Currently, most common cotton towel slitting devices use slitting blades or slitting discs for cutting. However, due to the softness and resilience of cotton towels, several problems often arise during the slitting process. When the slitting disc is not sharp enough, the cut edges of the cotton towels are prone to tearing. This not only severely affects the appearance quality of the cotton towels, leading to a higher defect rate and increased production costs, but also results in uneven edges during subsequent use, negatively impacting the user experience.

[0004] Therefore, it is necessary to provide a slitting device for the production and processing of cotton towels to solve the above-mentioned technical problems. Utility Model Content

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please refer to the following: Figures 1 to 4 A slitting device for cotton towel production includes: a frame 1, a roller assembly 2, a drive assembly 3, a slitting assembly 5, a mounting plate 6, and a waste assembly 7. The roller assembly 2 is mounted on the frame 1 to maintain the tension of the cotton towel during transport. The drive assembly 3 is mounted on the frame 1 to drive the punching assembly 4 and the slitting assembly 5 to punch and slit the cotton towel. The slitting assembly 5 is mounted on the frame 1 to slit the cotton towel. Two mounting plates 6 are provided, one on the front and one on the back of the frame 1. The waste assembly 7 is mounted on the frame. The bottom part is used to collect waste material from the edges of the cotton soft towel after slitting. It also includes a punching component 4, which is set on the frame 1 and located to the left of the slitting component 5. It is used to punch holes before slitting the cotton soft towel to facilitate subsequent slitting work. After the cotton soft towel enters the frame 1 through the unwinding device, it passes through the roller group 2 to ensure its tension. Then it enters the punching component 4 to punch holes in the slitting line in advance, and then enters the slitting component 5 for slitting. The waste material from the edges of the cotton soft towel enters the waste component 7, and is then rolled up by the take-up roller 203 in the roller group 2.

[0021] refer to Figure 1 , Figure 3 , Figure 4The punching assembly 4 includes: a lifting rod 401, punching needles 402, two contact plates 403, two cams 404, a transmission gear 405, a spring 406, and a fixing plate 407. Multiple sets of punching needles 402 are provided, all fixedly connected to the lifting rod 401, and are used to punch holes in the cotton towels before cutting. The two contact plates 403 are fixedly connected to both sides of the lifting rod 401. The two cams 404 are mounted on the frame 1 and positioned above the contact plates 403. A transmission gear 405 is fixedly connected to each cam 404. One end of the spring 406... The other end is fixedly connected to the bottom of the contact plate 403, and the fixed plate 407 is fixedly connected to the fixed plate 407. The fixed plate 407 is set on the frame 1. When the cotton towel passes under the punching assembly 4, the drive assembly 3 drives the transmission gear 405 to rotate, which in turn drives the cam 404 to rotate. After the cam 404 rotates, due to the eccentricity of the cam 404 itself, the spring 406 plate at the bottom of the contact plate 403 is compressed, the contact plate 403 moves down, which in turn causes the lifting rod 401 to move up and down, driving the punching needle 402 to punch holes in the cotton towel.

[0022] refer to Figures 1 to 3 The slitting assembly 5 includes a slitting roller 501, two transmission gears 502, and a slitting disc 503. The slitting roller 501 is mounted on the frame 1, and the two transmission gears 502 are fixedly connected to the slitting roller 501. Multiple slitting discs 503 are provided and are all fixedly connected to the slitting roller 501. When the cotton towel passes through the slitting assembly 5, the drive assembly 3 drives the transmission gears 502 to rotate, which in turn drives the slitting discs 503 on the slitting roller 501 to rotate, thereby slitting the cotton towel.

[0023] When the motor 301 drives the rotating rod 302 to rotate, the drive gear 303 in the middle of the rotating rod 302 also rotates. This drive gear 303 meshes with the transmission gear 502 of the slitting assembly 5, driving the transmission gear 502 to rotate, which in turn causes the slitting roller 501 to rotate. Multiple slitting discs 503 fixed on the slitting roller 501 then rotate, slitting the perforated cotton towel. During the slitting process, the cotton towel breaks smoothly along the perforation points, avoiding edge tearing.

[0024] The drive assembly 3 includes a motor 301, a rotating rod 302, and two drive gears 303. The motor 301 is fixedly connected to the mounting plate 6 on the front of the frame 1. The rotating rod 302 is fixedly connected to the drive end of the motor 301. The two drive gears 303 are respectively fixedly connected to the middle part of the rotating rod 302 and the end away from the drive end of the motor 301. The drive gear 303 at the end away from the drive end of the motor 301 meshes with the first transmission gear 405. The drive gear 303 in the middle of the rotating rod 302 meshes with the second transmission gear 502. After the motor 301 is started, the rotating rod 302 rotates, which drives the two drive gears 303 to rotate. Through meshing, the first transmission gear 405 and the second transmission gear 502 rotate, thereby driving the slitting roller 501 to rotate and move vertically to the lifting rod 401.

[0025] On the mounting plate 6 on the back, there is also a rotating rod 302 and two drive gears 303. The transmission gear 502 on the back of the slitting roller 501 drives one of the drive gears 303 on the back to rotate. The rotating rod drives the other drive gear 303 to rotate. Through meshing, the transmission gear 405 rotates, which in turn drives the cam 404 on the back to rotate, so as to ensure that the lifting rod 401 rises and falls in parallel on both sides and avoid the lifting rod 401 from getting stuck when it rises on one side.

[0026] The frame 1 includes: a base plate 101, two side plates 102, a piercing groove 103, a cutting groove 104, and a support frame 105. The base plate 101 is fixedly connected to the side plates 102. Two mounting plates 6 are fixedly connected to the front and rear sides of the side plates 102. The lifting rod 401 passes through the side plates 102 and is slidably connected at the through point of the side plates 102. The piercing groove 103 is opened on the base plate 101 and is located below the piercing assembly 4 so that the piercing needle 402 can pass through and avoids it from hitting the base plate 101 and causing movement interference. The cutting groove 104 is opened on the base plate 101 and is located below the slitting assembly 5 so as to prevent the slitting disc 503 from cutting the base plate 101. The support frame 105 is fixedly connected to the bottom of the base plate 101 and is used to support the mounting device.

[0027] refer to Figure 1 , Figure 2 The roller assembly 2 includes: a first pressure roller 201, a second pressure roller 202, and a take-up roller 203. Both the first pressure roller 201 and the second pressure roller 202 are located inside the frame 1. The first pressure roller 201 is located to the left of the punching assembly 4, and the second pressure roller 202 is located to the right of the slitting assembly 5, so that the first pressure roller 201 and the second pressure roller 202 can press the cotton soft towel tightly, maintain the tension of the cotton soft towel, and ensure that the punching assembly 4 and the slitting assembly 5 can work normally. The take-up roller 203 is located to the right of the second pressure roller 202, and two rollers are provided for cross-winding the slitting cotton soft towel.

[0028] The waste component 7 includes a waste outlet 701 and a waste guide plate 702. There are two waste outlets 701, which are located at the bottom of the base plate 101. The waste guide plate 702 is fixedly connected to the bottom of the base plate 101 and is located below the waste outlets 701. After the cotton towel is cut, the waste material at the edge enters the waste guide plate 702 through the waste outlets 701 and is guided to the outside of the device.

[0029] The working principle of the slitting device for cotton towel production and processing provided by this utility model is as follows:

[0030] Motor 301 starts, driving the rotating rod 302 to rotate, which in turn causes the drive gear 303 on the rotating rod 302, away from the driving end of motor 301, to rotate. This drive gear 303 meshes with transmission gear 405, driving transmission gear 405 to rotate, thereby causing the cam 404 fixed on transmission gear 405 to rotate. Due to the eccentricity of the cam 404, during rotation, it compresses the spring 406 at the bottom of the contact plate 403, causing the contact plate 403 to move downwards, which in turn causes the lifting rod 401 to move up and down. The needle 402 fixed on the lifting rod 401 then punches holes in the cotton towel slitting line. After punching, the cam 404 continues to rotate, the spring 406 returns, causing the lifting rod 401 to rise and reset, ready for the next punching operation.

[0031] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
