Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric production technology, specifically a nonwoven fabric cutting device. Background Technology

[0002] In existing technologies, there are two main methods for cutting nonwoven fabrics. One method involves using a cutter to cut the nonwoven fabric into strips according to size requirements during the winding process, and then winding the strips back together. The other method involves first winding the nonwoven fabric and then using a cutting device to cut the large roll of nonwoven fabric into strips according to size requirements.

[0003] The equipment used for the second type of cutting method is usually called a fabric strip cutter. The fabric strip cutter typically places a roll of non-woven fabric on a rotating roller, and then uses a high-speed rotating cutter to cut the non-woven fabric roll into small segments. Since the roller and the non-woven fabric roll have a certain weight, both ends of the roller need to be supported by roller seats to ensure that the roller rotates smoothly and does not rotate centrifugally. At the same time, since the non-woven fabric roll needs to be placed on or removed from the roller frequently, the roller seats need to be disassembled and reassembled frequently, wasting a lot of time and resulting in low fabric cutting efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a nonwoven fabric cutting device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a non-woven fabric cutting device, including a fabric strip cutting machine, a roller seat is provided on the corresponding frame inside the fabric strip cutting machine, the roller seat is used to support the central shaft of the corresponding roller in the fabric strip cutting machine, the roller seat includes a rotating shaft, a swing arm and a roller support seat, the rotating shaft is rotatably mounted on the frame, the roller support seat is transitionally connected to the rotating shaft through the swing arm, and two roller support rollers for supporting the central shaft of the roller are symmetrically arranged on the roller support seat.

[0006] The frame is also fixed with a lock body in the form of a column. The lock body is arranged coaxially with the rotating shaft.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figure 1 and Figure 2 As shown, a nonwoven fabric cutting device includes a fabric strip cutter 1.

[0017] The fabric strip cutting machine 1 is existing technology. For ease of understanding, the main structure of the fabric strip cutting machine 1 is briefly described below: The fabric strip cutting machine 1 mainly consists of a frame 11, a roller 12 and a cutting machine 13. The roller 12 is rotatably mounted on the frame 11, and a drive motor for driving the roller 12 to rotate is also mounted on the frame 11. The cutting machine 13 is slidably mounted on one side of the roller 12, and the cutting machine 13 can slide laterally and longitudinally in the horizontal plane.

[0018] The common sliding method for the cutting machine 13 is a connection of linear guide rails and sliders. For example, a mounting base is mounted on the frame 11 via linear guide rails and sliders that slide laterally. The cutting machine 13 is mounted on the mounting base via linear guide rails and sliders that slide longitudinally. In this way, the cutting machine 13 can move both longitudinally and laterally within a horizontal plane on the frame 11. Of course, the frame 11 is also equipped with a drive mechanism for driving the lateral sliding of the mounting base, and the mounting base is equipped with a drive mechanism for driving the longitudinal sliding of the cutting machine. Both drive mechanisms are usually driven by lead screw motors.

[0019] The frame 11 is also equipped with a drive motor for rotating the roller 12. The wound nonwoven fabric is placed on and fixed to the roller 12. Driven by the drive motor, the roller 12 rotates the nonwoven fabric roll, while simultaneously controlling the cutter 13 to approach the nonwoven fabric roll. Under the cutting action of the high-speed rotating blade of the cutter 13, the nonwoven fabric roll is cut. The rotation of the roller 12 ensures that the nonwoven fabric roll rotates during cutting, allowing it to make uniform circumferential contact with the cutter, guaranteeing a clean cut.

[0020] Typically, the fabric strip cutting machine 1 also includes a PLC controller for automatically controlling the rotation of the roller 12 and the cutting and movement of the cutter 13. The above is a brief description of the main structure of the fabric strip cutting machine 1 for ease of understanding. The above content is an introduction to the main structure and functions of the fabric strip cutting machine 1. The above structure and functions belong to existing technology; other detailed structures and functions will not be elaborated upon here.

[0021] Specifically, in this embodiment, the frame 11 of the fabric cutting machine 1 is provided with a roller seat 2 for supporting the roller shaft 12. The roller seat 2 includes a rotating shaft 21, a swing arm 22 and a roller support seat 23. The rotating shaft 21 is rotatably mounted on the frame 11 corresponding to the fabric cutting machine 1. The roller support seat 23 is transitionally connected to the rotating shaft 21 through the swing arm 22. Two roller support rollers 24 for supporting the central axis of the roller shaft 12 are symmetrically arranged on the roller support seat 23.

[0022] like Figures 3 to 13 As shown, a columnar lock body 3 is also fixed on the frame 11. The lock body 3 is coaxially arranged with the rotating shaft 21. A lock groove 31 is provided on the side of the lock body 3 facing the rotating shaft 21. The lock groove 31 consists of a locking part 311 and an adjusting part 312. A lock head 25 is provided on the rotating shaft 21, extending into the lock groove 31. The shape of the lock head 25 is consistent with the shape of the locking part 311. A through hole 33 communicating with the adjusting part 312 is provided on the side of the lock body 3 facing away from the rotating shaft 21. A lock cap 4 is slidably provided on the outer side of the lock body 3. The sliding direction of the lock cap 4 is the extension direction of the axis of the lock body 3. A lock block 41 is provided inside the lock cap 4. The lock block 41 passes through the through hole 33 and extends into the adjusting part 312. Driving the lock cap 4 away from the rotating shaft 21 can disengage the lock block 41 from the adjusting part 312.

[0023] Working principle: When it is necessary to add or remove nonwoven fabric rolls from roller 12, the locking cap 4 is first driven to move away from the rotating shaft 21 along the axis of the locking body 3. During this process, the locking block 41 inside the locking cap 4 moves accordingly and gradually disengages from the adjusting part 312 in the locking groove 31. After the locking block 41 is completely disengaged from the adjusting part 312, since the locking head 25 is only consistent with the shape of the locking part 311 and is not restricted by the locking block 41 at this time, the locking head 25 can rotate into the adjusting part 312. Then, the rotating shaft 21 can drive the swing arm 22 and the roller support seat 23 to rotate around its own axis, thereby causing the roller support wheel 24 to rotate and move away from the roller 12. At this time, the side of the roller 12 facing the roller support seat 2 is suspended, which facilitates the addition or removal of nonwoven fabric rolls. After adding or removing nonwoven fabric rolls, rotate the shaft 21 to a suitable angle so that the locking head 25 rotates back into the locking part 311 of the locking groove 31. Then push the locking cap 4 to move towards the shaft 21. The locking cap 4 drives the locking block 41 through the insertion hole 33 into the adjustment part 312, and finally makes the locking block 41 lock into the locking part 311. At this time, the locking head 25 is restricted in the locking part 311 by the locking block 41, and the shaft 21 cannot rotate, thereby ensuring that the position of the roller seat 2 is fixed, so that the roller seat 2 remains stable during the operation of the entire nonwoven fabric cutting device, ensuring the normal operation of the nonwoven fabric cutting work.

[0024] Furthermore, such as Figure 8 As shown, a limiting groove 32 is provided around the side of the locking groove 31 facing the roller shaft 12. The limiting groove 32 is designed to be a circular groove with a diameter that matches the central axis of the roller shaft 12. The limiting groove 32 is used to accommodate a part of the rotating shaft 21. The limiting groove 32 can play a precise positioning role, ensuring that the locking head 25 is accurately aligned with the locking part 311 of the locking groove 31. At the same time, the limiting groove 32 can also provide a certain support and stability for the rotating shaft 21, reduce the shaking of the rotating shaft 21 during rotation, and improve the stability of the entire roller shaft seat 2 structure.

[0025] Furthermore, such as Figures 9 to 12 As shown, the lock body 3 is provided with a guide groove 36, and the lock cap 4 is provided with a guide post 42 that slides in cooperation with the guide groove 36. When the lock cap 4 is driven to slide along the axial direction of the lock body 3, the guide post 42 slides in the guide groove 36, which further ensures the straightness and accuracy of the sliding of the lock cap 4 and avoids the lock cap 4 from deviating during the sliding process, which would affect the cooperation accuracy between the lock block 41 and the lock groove 31.

[0026] Furthermore, such as Figure 7 , Figures 11 to 13As shown, a guide hole 34 coaxially arranged with the lock body 3 is provided through the lock body 3. A guide rod 5 that slides with the guide hole 34 is provided inside the lock cap 4. A limit cap 51 is provided at the suspended end of the guide rod 5. A second limit groove 35 for accommodating the limit cap 51 is provided on the lock body 3 and around the guide hole 34. An obstacle hole 26 for the limit cap 51 to pass through is provided on the lock head 25. After the lock cap 4 is pulled outward so that the limit cap 51 is inserted into the second limit groove 35, the lock block 41 is completely disengaged from the adjustment part 312. Under the limiting action of the second limit groove 35 on the lock block 41, the lock cap 4 is prevented from continuing to move outward, ensuring that the lock cap 4 will not be disengaged from the lock body 3 due to excessive pulling. The function of the clearance hole 26 is to provide passage space for the limit cap 51, avoid interference between the limit cap 51 and the lock head 25, ensure that the lock cap 4 can slide smoothly along the axis of the lock body 3 and allow the lock block 41 to enter the adjustment part 312 normally.

[0027] Specifically, such as Figure 10 and Figure 13 As shown, the lock cap 4 is provided with a threaded hole 43, and the guide rod 5 is provided with a thread that cooperates with the threaded hole 43. The lock cap 4 and the guide rod 5 are connected by a threaded connection. The purpose of the threaded installation is to realize the detachable connection between the guide rod 5 and the lock cap 4, so as to facilitate the disassembly and assembly of the lock body 3 and the lock cap 4.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
