Description

Technical Field

[0001] The utility model relates to the field of non-woven fabric production and manufacturing, in particular to a non-woven fabric slitting device. Background Art

[0002] Non-woven fabric, also known as non-woven fabric, is a kind of fabric that is not made by traditional textile process. It is a flat non-woven fabric made by melting, stretching, and then rapidly cooling and solidifying polymer slices. Since the production process does not require spinning and weaving, it is named "non-woven". Non-woven fabric is widely used in medical and health care and industrial packaging fields because of its uniform structure, light weight, good softness, good air permeability and moisture absorption.

[0003] After non-woven fabrics are produced, they need to be cut to meet the needs of different sizes. The traditional technology uses manual cutting. The size of the non-woven fabrics cut in this way is not uniform, the precision is poor, and it is time-consuming and labor-intensive. With the development of science and technology, people began to promote slitting devices. However, in the existing technology, the slitting of non-woven fabrics is mostly done by pushing the pushing mechanism first, and then cutting by the cutting mechanism. This will result in uneven cutting and lack of continuity. The cutting mechanism and the pushing structure need to work closely together, which requires the control of precision instruments, resulting in an increase in the production cost of the cutting equipment and the maintenance cost of the later equipment, which is a heavy burden for some small manufacturers.

[0004] In view of this, it is necessary to improve the above defects. Utility Model Content

DETAILED DESCRIPTION

[0021] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 7 As shown, the utility model proposes a non-woven fabric slitting device, which includes a support plate 1, a connection part 2 is fixedly connected to the top of the support plate 1, and a bottom block 3 and a bottom block 2 4 are fixedly connected to both sides of the connection part 2, and a longitudinally arranged middle axis 1 5 and a middle axis 2 6 are respectively inserted in the bottom block 1 3 and the bottom block 2 4, and an eccentric wheel 1 7 and an eccentric wheel 2 8 are fixedly connected to the rear ends of the middle axis 1 5 and the middle axis 2 6, respectively, and the eccentric orientations of the eccentric wheel 1 7 and the eccentric wheel 2 8 are consistent, so the eccentric wheel 1 7 and the eccentric wheel 2 8 can rotate synchronously, and in order to drive them to rotate, the utility model passes through the eccentric wheel 2 8 at the rear end of the middle axis 2 6 and is fixedly connected to a motor 28, and a motor seat 29 is fixedly connected to one side of the motor 28, and the motor seat 29 is fixedly connected to the support plate 1. When the motor 28 is powered on, the driving of the eccentric wheel 2 8 can be completed.

[0024] At the same time, the outer parts of the eccentric wheel 1 7 and the eccentric wheel 2 8 are respectively sleeved with a bearing part 1 9 and a bearing part 2 10, and the bearing part 1 9 and the bearing part 2 10 are connected to each other by a connecting part 2 11. Therefore, when the eccentric wheel 2 8 is rotated by force, the eccentric wheel 2 8 will make a circular motion around the central axis 2 6 due to the influence of the eccentricity, and correspondingly, it will drive the bearing part 2 10 to make a circular motion, thereby driving the bearing part 1 9 to make a synchronous circular motion. At this time, the eccentric wheel 1 7 will also make a synchronous circular motion. Since the central axis 1 5 is fixed on the eccentric of the eccentric wheel 1 7, the circular motion of the eccentric wheel 1 7 will drive the eccentric to rotate, thereby driving the central axis 1 5 to rotate.

[0025] Next, the front ends of the middle shaft 1 5 and the middle shaft 2 6 are respectively fixedly connected with a rotating plate 12 and a rotating plate 2 13, and the front bottoms of the rotating plates 12 and 13 are respectively fixedly connected with an inserting shaft 14 and an inserting shaft 2 15. Due to the circular motion of the middle shaft 1 5 and the middle shaft 2 6, the rotating plates 12 and 13 will respectively drive the inserting shaft 14 and the inserting shaft 2 15 to rotate synchronously, and the front end of the inserting shaft 14 is rotatably connected with a movable receiving seat 16, and the front end of the inserting shaft 2 15 is fixedly connected with a trapezoidal gear 2 17, and the front end of the movable receiving seat 16 is plugged with a horizontally arranged rotating shaft 18, and the two ends of the rotating shaft 18 are respectively fixedly connected with a cutting portion 19 and a trapezoidal gear The first 20, the trapezoidal gear 1 20 is located on the side close to the second trapezoidal gear 17 and meshes with it, so when the plug shaft 14 makes a circular motion around the middle axis 1 5, it will drive the mobile receiving seat 16 to make a synchronous circular motion, and the plug shaft 15, the trapezoidal gear 17 and the rotating plate 13 are all fixed, so the relative position of the rotating plate 13 relative to the trapezoidal gear 17 is unchanged, and the rotating plate 13 makes a circular motion relative to the middle axis 2 6, so the trapezoidal gear 17 also realizes rotation, and because it meshes with the trapezoidal gear 1 20, the rotation of the trapezoidal gear 17 can drive the rotating shaft 18 to drive the cutting part 19 to rotate, thereby realizing cutting. The side of the mobile receiving seat 16 close to the plug shaft 15 is fixedly connected with a rotating fixed seat 30, and the plug shaft 15 is inserted into the rotating fixed seat 30, so the movement of the trapezoidal gear 17 and the mobile receiving seat 16 is linked.

[0026] Then, the front middle part of the mobile receiving seat 16 is fixedly connected with an L-shaped downward positioning shaft 21, and the positioning shaft 21 is sleeved with a positioning seat 22. The front end of the positioning seat 22 is fixedly connected with a mobile clamping frame 23 used in conjunction with the cutting part 19, and a clamping structure 24 is arranged in the mobile clamping frame 23. The bottom end of the mobile clamping frame 23 is slidably connected with a slide seat 25, and the bottom end of the slide seat 25 is fixedly connected with a base 26, and one end of the base 26 close to the cutting part 19 is fixedly connected with a discharge channel 27. A cutting groove 35 used in conjunction with the cutting part 19 is provided on the side of the mobile clamping frame 23 close to the cutting part 19. Therefore, during the circular motion of the mobile receiving seat 16, a lateral and vertical displacement will be generated, and the lateral displacement will drive the positioning seat 22 to move back and forth laterally, and with the clamping and loosening of the clamping structure 24, the non-woven fabric roll inside can be pushed. When the non-woven fabric roll is pushed to the tail, the cutting part 19 just falls down, and the cutting is completed. The process repeats itself over and over again to achieve synchronization of pushing and cutting.

[0027] The clamping structure 24 includes a push-pull plate 31 arranged at the front end of the mobile clamping frame 23, and telescopic cylinders 32 are fixedly connected to both sides of the rear end of the push-pull plate 31. The telescopic cylinders 32 are fixedly connected to the front end of the mobile clamping frame 23, and push-pull shafts 33 fixedly connected to the push-pull plate 31 are arranged on the adjacent sides of the telescopic cylinders 32 on both sides. The push-pull shafts 33 pass through the mobile clamping frame 23 and are fixedly connected to the clamping plate 34.

[0028] It should be specially noted here that the components described and identified in the text and drawings of the utility model are the key components constituting the utility model, and the remaining non-key components or obvious prior art components, such as screws, nuts and other connectors, and technical features similar to the prior art are not shown. However, this does not mean that the above-mentioned components do not exist in the utility model, nor can it be interpreted as a practical limitation on the utility model.

[0029] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
