Description

Technical Field

[0001] This invention relates to the field of fabric processing equipment technology, specifically to a self-adjusting fabric roller slitting device. Background Technology

[0002] In the production and subsequent processing of textile fabrics, it is usually necessary to cut whole rolls of fabric into rolls of different lengths according to actual usage requirements to meet packaging, transportation, and subsequent processing needs. Most existing fabric roller slitting equipment is designed for fabric rollers of fixed specifications. When it is necessary to process fabric rollers of different lengths or diameters, it is usually necessary to manually adjust the limiting mechanism or replace the adaptable parts. This adjustment process is not only cumbersome but also time-consuming, reducing production efficiency.

[0003] Meanwhile, some existing equipment lacks effective end-position limiting structures during the cloth roller rotation cutting process, or the limiting structure has a limited adjustment range. When the specifications of the cloth roller change, it is easy to have insufficient adaptability, which causes the cloth roller to move axially or shift during the cutting process, thereby affecting the cutting accuracy and processing quality.

[0004] In addition, the existing equipment commonly uses rigid limiting methods. When the cloth roller undergoes a small displacement due to vibration, force changes or cutting resistance changes during rotation, the rigid limiting structure is difficult to compensate for. This can easily cause problems such as cloth roller deformation under pressure, increased cutting deviation, and accelerated wear of limiting components, affecting the stable operation of the equipment.

[0005] Therefore, it is necessary to provide a self-adjusting fabric roller slitting device that can adapt to fabric rollers of different lengths and diameters and can achieve automatic adjustment and elastic compensation limit, so as to solve the problems existing in the prior art. Summary of the Invention

[0006] The purpose of this invention is to provide a self-adjusting fabric roller slitting device to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a self-adjusting fabric roller slitting device, comprising: a base frame, an active roller rotatably connected to the base frame, a toothed disc fixedly connected to one end of the active roller, two first slide blocks slidably connected to the base frame, and a driven roller rotatably connected between the two first slide blocks; Two electric cylinders are fixedly installed on the base frame, and the telescopic ends of the electric cylinders are respectively connected to the corresponding first slide blocks for transmission. Rotate the positive and negative threaded rods connected to the base frame; Two second slides are respectively threaded onto the reverse threaded portions on both sides of the positive and negative threaded screw; A support rod fixedly connected to the top of the second slide; A limiting plate is provided at the end of the support rod; A servo motor is fixedly installed at one end of the base frame, and the drive end of the servo motor is connected to the forward and reverse threaded screw transmission. The space between the active roller and the driven roller is used to place the fabric roller, and the two electric cylinders are used to drive the first slide to move in order to adjust the distance between the active roller and the driven roller. The two second slide blocks can move synchronously towards or away from each other under the drive of the positive and negative screw rods, so as to drive the two limit plates to adjust the distance and abut against the two ends of the fabric roller respectively; A buffer adjustment assembly is provided between the limiting plate and the support rod so that the limiting plate can move elastically along the length of the support rod. The electric cylinder adjusts the distance between the driving roller and the driven roller, and the positive and negative threaded screws drive the limit plate to adjust the position synchronously, so as to realize the automatic adaptation of cloth rollers of different lengths and diameters, improve the cutting stability and application range, and reduce the amount of manual adjustment work.

[0008] Preferably, the buffer adjustment assembly includes a connecting arm, a threaded rod, a buffer spring, and a nut. The connecting arm is fixedly connected to the side of the limiting plate facing the support rod. The threaded rod is fixedly connected to the limiting plate and passes through the support rod. The buffer spring is sleeved on the outside of the threaded rod. The nut is threadedly connected to the end of the threaded rod. The connecting arm, threaded rod, buffer spring, and nut constitute a buffer adjustment assembly, which enables the limiting plate to have elastic compensation capability, absorb displacement changes during the fabric roller cutting process, improve limiting stability, and reduce impact.

[0009] Preferably, the buffer spring is located between the support rod and the limiting plate, and continuously applies an elastic preload force toward the fabric roller to the limiting plate; By continuously applying preload to the limiting plate through the buffer spring, the limiting plate is kept in contact with the end face of the fabric roller, maintaining reliable positioning during the slitting process and reducing axial movement of the fabric roller.

[0010] Preferably, the nut is used to adjust the initial position of the limiting plate relative to the support rod and to disassemble and replace the buffer spring; The initial position of the limit plate and the spring compression can be adjusted by adjusting the nut, which can adjust the buffer range according to different working conditions and facilitates the disassembly and replacement of the buffer spring.

[0011] Preferably, two first slide rods are fixedly connected to the base frame, and two second slide blocks are slidably connected to the corresponding first slide rods; The second slide block is guided and supported by the first slide rod, ensuring that the second slide block moves stably in the predetermined direction.

[0012] Preferably, two second sliding rods are fixedly connected to the base frame, and the two second sliding rods are respectively disposed on both sides of the corresponding support rod, and the limiting plate is slidably connected to the corresponding second sliding rod; The second slide bar guides and constrains the limiting plate, ensuring that the limiting plate moves smoothly in a straight line.

[0013] Preferably, the length of the limiting plate is greater than the maximum adjustment stroke of the driven roller, so as to ensure that the limiting plate can still limit the two ends of the fabric roller after the driven roller moves.

[0014] Preferably, a mounting base is fixedly installed on the base frame. The mounting base is used to install a fabric roller cutter to perform a cutting operation on the fabric roller between the drive roller and the driven roller.

[0015] Preferably, the top of the base frame has two pairs of oppositely arranged sliding openings, and the two first sliding blocks are slidably connected to the corresponding sliding openings.

[0016] Preferably, the toothed disc is used to be connected to an external drive mechanism via a toothed chain to drive the active roller to rotate the fabric roller.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: Firstly, by driving the first slide block to move via an electric cylinder, the distance between the active roller and the driven roller can be automatically adjusted, which can quickly adapt to cloth rollers of different diameters. At the same time, by using a servo motor to drive the positive and negative threaded rods to drive two sets of limit plates to adjust the distance synchronously, the automatic positioning of cloth rollers of different lengths can be achieved, thereby improving the applicability and adjustment efficiency of the equipment and reducing the amount of manual adjustment work. Secondly, it adopts an elastic limiting structure with a buffer spring, which can compensate for and absorb the slight axial displacement of the fabric roller during the cutting process, avoiding the squeezing deformation and cutting deviation caused by rigid limiting. At the same time, the buffer spring can be quickly disassembled and replaced with a nut, improving the convenience of equipment maintenance and long-term operational stability.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-9 The present invention provides a technical solution: a self-adjusting fabric roller slitting device, comprising: a base frame 1, the top of the base frame 1 having two pairs of oppositely arranged sliding openings, two first sliding blocks 3 respectively slidably connected to the corresponding sliding openings, a driven roller 4 rotatably connected between the two first sliding blocks 3, a driving roller 2 rotatably connected to the base frame 1, one end of the driving roller 2 being fixedly connected to a toothed disc 6; two electric cylinders 5 corresponding to the first sliding blocks 3 are fixedly installed on the base frame 1, the extension and retraction ends of the two electric cylinders 5 being respectively connected to the corresponding first sliding blocks 3, for adjusting the distance between the driving roller 2 and the driven roller 4.

[0023] The base frame 1 is rotatably connected to a positive and negative threaded rod 9. The positive and negative threaded rod 9 is threaded to two sides of a second slide block 10. The top of the two second slide blocks 10 is fixedly connected to a support rod 11. The end of the support rod 11 is provided with a limiting plate 12. A servo motor 18 is fixedly installed at one end of the base frame 1. The servo motor 18 drives the positive and negative threaded rod 9 to rotate forward or backward, so as to realize that the two limiting plates 12 move closer or further away synchronously.

[0024] Two first slide rods 7 are fixedly connected to the base frame 1, and the second slide block 10 is slidably connected to the first slide rods 7; two second slide rods 8 are also fixedly connected to the base frame 1, and the limiting plate 12 is slidably connected to the second slide rods 8 to improve motion stability.

[0025] The limiting plate 12 is fixedly connected to the connecting arm 13 on the side facing the support rod 11. The threaded rod 14 is fixedly connected to the middle of the limiting plate 12. The threaded rod 14 passes through the support rod 11 and extends to the other side. The threaded rod 14 is fitted with a buffer spring 15. The end of the threaded rod 14 is threadedly connected to a nut 16. The distance between the limiting plate 12 and the support rod 11 can be adjusted by adjusting the position of the nut 16, and the buffer spring 15 can be installed and removed at the same time.

[0026] A mounting base 17 is fixedly installed on the base frame 1. The mounting base 17 is used to install the fabric roller cutting machine.

[0027] A specific application of this embodiment is as follows: When in use, firstly, control the two electric cylinders 5 to extend and retract synchronously according to the diameter of the fabric roller to be processed, drive the two first slide blocks 3 to move, thereby adjusting the distance between the active roller 2 and the driven roller 4, so that the fabric roller can be stably placed between the active roller 2 and the driven roller 4. Then, the servo motor 18 is started to drive the positive and negative threaded screws 9 to rotate, which drives the two second slide blocks 10 to move synchronously towards each other or away from each other, so that the two limit plates 12 respectively abut against the two ends of the fabric roller and complete the length direction positioning. Then, the drive roller 2 is driven to rotate by the external toothed chain drive mechanism connected by the toothed disc 6. The drive roller 2, in conjunction with the driven roller 4, drives the fabric roller to rotate. At the same time, the cutting machine installed on the mounting base 17 performs slitting operation on the fabric roller. During the cutting process, when the fabric roller experiences a small range of axial displacement due to vibration or force changes, the limiting plate 12 can compress the buffer spring 15 under the guidance of the threaded rod 14 to provide elastic compensation, thereby continuously maintaining stable limiting of both ends of the fabric roller. When the buffer spring 15 becomes fatigued or the preload needs to be adjusted, the buffer spring 15 can be replaced or adjusted by unscrewing the nut 16 to ensure the long-term stable operation of the equipment.
