Description

Technical Field

[0001] The invention relates to the technical field of cloth winding, in particular to a warp knitted cloth winding and splitting mechanism. Background Art

[0002] Fabric winding mainly refers to winding the fabric from one side into a cylindrical or conical roll of a certain diameter for subsequent processing, transportation and storage.

[0003] Patent No. 201910793708.X proposes to wind up a whole roll of fabric into multiple rolls of fabric, but the existing fabric winding and unwinding mechanism has a complex structure and is difficult to install. It generally requires the whole roll of fabric to be installed on the fabric roll roller, and then the two ends of the fabric roll roller are fixed on two roll seats or unwinding seats, which is difficult to install and disassemble. In addition, the fabric winding and unwinding mechanism is set to be easy to install and disassemble, and it is still necessary to open and remove the rolled fabric, and then install and tighten the new roll roller. The structure is more complicated, and the fabric roll roller cannot be installed and disassembled too simply. In addition, if the cloth is not handled properly when it is rolled, the edges of the cloth may roll up or wrinkle, and the end faces of the cloth may also be uneven. Even if the cloth is rolled up, it is difficult to meet the requirements of rolling up. The cloth needs to be aligned with the reel roller and a stable straightening effect needs to be generated to avoid the deviation of the cloth. However, during the rolling and rolling process, the cloth needs to be wound onto different reel rollers, and it is difficult to control the degree of tension. Based on this, it is necessary to solve the problem of facilitating the removal and placement of the reel rollers and the problem of uneven end faces of the cloth. Summary of the invention

[0004] The object of the present invention is to provide a warp knitted fabric winding and splitting mechanism to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a warp knitted fabric winding and rolling mechanism, comprising an outer bracket and a winding portion arranged on the outer bracket, the winding portion having two groups of support ends, multiple groups of support portions distributed circumferentially between the two groups of support ends, the multiple groups of support portions can be extended and retracted inward and outward, and a winding roller is clamped between the multiple groups of support portions, the winding roller is used to roll up the fabric, and the rolled fabric is supported on the inner side of the multiple groups of support portions.

[0006] Furthermore, a transmission shaft for supporting the cloth is fixed to the upper end of the outer bracket.

[0007] Further, the support end includes a limiting inner ring and a limiting outer ring, both of which are fixed on the outer bracket, the limiting inner ring is sleeved inside the limiting outer ring, and the axes of the two coincide, and a gusset plate is distributed on the circumference of the inner side of the limiting inner ring, and the support part is slidably arranged in the gusset plate, so that the support part can slide;

[0008] A frame plate is fixed on the outer side of the limiting inner ring of the support end on one side, a winding motor is fixed on the outer side of the frame plate, and the output end of the winding motor cooperates with the winding roller.

[0009] Furthermore, a polygonal shaft is integrally formed at the output end of the winding motor, and the end of the winding roller has a polygonal opening. The polygonal shaft cooperates with the polygonal opening to drive the winding roller to rotate.

[0010] Furthermore, the support part includes symmetrically arranged sliding frames, which are symmetrically slidably clamped into the buckle plates on both sides respectively, and support springs are fixed between the ends of the sliding frames and the limiting outer rings, and the support springs are used for supporting. A horizontal axis is fixed between the symmetrical sliding frames, and the outward side of the horizontal axis has a recess, and a support shaft body is rotatably installed in the recess of the horizontal axis, and the support shaft body is used for squeezing the rolled cloth.

[0011] Furthermore, an annular groove is provided at the end of the support shaft body, a plurality of slits are provided inside the support shaft body, the slits are connected to the annular groove, a plurality of circumferentially distributed transverse grooves are provided on the outside of the support shaft body, an inclined hole is provided in the transverse groove, and air blown out from the inclined hole is used to smooth the fluff on the cloth in one direction, and an air inlet hole is provided on the outside of the sliding frame on one side, and the air inlet hole is connected to the annular groove.

[0012] Furthermore, an inner ball is rotatably mounted inside the support shaft, and the support shaft extends from one side of the inner ball. The support shaft is used for squeezing with the cloth.

[0013] Furthermore, the outer wall of the support shaft is roughly configured, and the length of the support shaft is greater than the width of the cloth to be rolled.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0015] 1. The polygonal opening at the end of the winding roller cooperates with the polygonal shaft of the winding motor to wind up the fabric. The wound fabric can be directly taken out of the winding roller horizontally, which is convenient for direct placement.

[0016] 2. During the winding process of the winding roller, the outer side of the rolled fabric is supported by the supporting part, so that the rolled fabric is prevented from becoming loose, the winding roller is prevented from deviating during rotation, and the edge of the fabric is prevented from rolling up or wrinkling. This can make the rolled fabric fit better and ensure that the fabric remains tight during the winding process to avoid gaps or looseness.

[0018] 4. The gas moves out from the inclined hole, producing a lateral blowing effect on the cloth that is about to contact the supporting shaft, causing the fluff on the cloth to tilt roughly to one side to a certain extent. The fluff is squeezed during the cloth winding process, which makes it easy to shape the fluff on the cloth. The fluff is roughly shaped in one direction, which can improve the appearance of the cloth. After the cloth contacts the inner ball, there is a gap around it, which can make the gas move and avoid blockage. The inner ball can be rotated under force, making it easy to drag the winding roller out after winding. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-Figure 10 The present invention provides a technical solution: when the rolled fabric is easy to be divided into rolls, in order to facilitate the installation and removal of the fabric, it is easy to cause unstable tension control, resulting in local wrinkles and slack. In addition, when the rolled fabric is divided into rolls, the edge of the fabric is easy to roll up or wrinkle during the installation and removal of the fabric, and the end surface of the fabric may also be uneven. For this reason, a warp knitted fabric winding and dividing mechanism is proposed, including an outer bracket 1 and a winding portion 3 arranged on the outer bracket 1, the winding portion 3 has two groups of support ends 31, and multiple groups of support portions 32 are circumferentially distributed between the two groups of support ends 31. The multiple groups of support portions 32 can be retracted inside and outside, and a winding roller 36 is clamped between the multiple groups of support portions 32. The winding roller 36 is used to roll up the fabric, and the rolled fabric is supported on the inner side of the multiple groups of support portions 32. The multiple groups of support portions 32 are used to support the rolled fabric and keep the winding roller 36 stable. The support portion 32 It helps to maintain the balance of the winding roller 36, ensures that the cloth can be evenly and tightly wound around the shaft, assists in adjusting the tension of the cloth during the winding process, prevents the cloth from breaking due to excessive tension or loosening due to insufficient tension, and improves the winding efficiency.

[0033] like Figure 2 As shown, a transmission shaft 2 for supporting the cloth is fixed to the upper end of the outer bracket 1, and the cloth is wound around the transmission shaft 2 to support the cloth.

[0034] like Figure 4As shown, the support end 31 includes a limiting inner ring 311 and a limiting outer ring 313, both of which are fixed on the outer bracket 1, and the limiting inner ring 311 is sleeved inside the limiting outer ring 313, and the axes of the two coincide. A buckle plate 312 is distributed on the inner side of the limiting inner ring 311, and the support part 32 is slidably arranged in the buckle plate 312 so that the support part 32 can slide. The functions of the limiting inner ring 311 and the limiting outer ring 313 are to support the support part 32 so that the support part 32 can slide. It expands outward and resets under the action of the support spring 322, so that the support part 32 supports the winding roller 36 to compact the wound cloth. The multiple groups of support parts 32 compact the wound cloth over a wider range. In addition, the winding roller 36 maintains a stable rotation during rotation to avoid deviation and uneven winding of the cloth. In particular, when the winding roller 36 can be removed directly, in order to facilitate the removal of the winding roller 36, multiple groups of support parts 32 are provided for support to maintain stability.

[0035] like Figure 5 As shown, a frame plate 33 is fixed on the outside of the limiting inner ring 311 of the support end 31 on one side, and a winding motor 34 is fixed on the outside of the frame plate 33. The output end of the winding motor 34 cooperates with the winding roller 36. During the winding process, the winding motor 34 drives the winding roller 36 to rotate, so that the winding roller 36 rotates during the winding process, so that the cloth is pulled and winding is achieved.

[0036] like Figure 5 As shown, the output end of the winding motor 34 is integrally formed with a polygonal shaft 35, and the end of the winding roller 36 has a polygonal opening 37. The polygonal shaft 35 cooperates with the polygonal opening 37 to drive the winding roller 36 to rotate. The output end of the winding motor 34 can directly cooperate with the winding roller 36, based on which the winding roller 36 can be directly removed, which facilitates the installation and disassembly of the winding roller 36 that has completed winding, thereby improving efficiency.

[0037] like Figure 7As shown, the support portion 32 includes symmetrically arranged sliding frames 321, and the symmetrical sliding frames 321 are respectively slidably clamped in the buckle plates 312 on both sides. A support spring 322 is fixed between the end of the sliding frame 321 and the limiting outer ring 313. The support spring 322 is used for supporting. A horizontal axis 323 is fixed between the symmetrical sliding frames 321. The side of the horizontal axis 323 facing outward has a recess. A support shaft body 325 is rotatably installed in the recess of the horizontal axis 323. The support shaft body 325 is used to squeeze the rolled cloth. The support shaft body 325 is in direct contact with the rolled cloth. In addition, the supporting function is achieved, and the support shaft 325 can rotate to avoid sliding friction with the cloth. As the winding diameter of the winding roller 36 increases, the support shaft 325 gradually moves outward to squeeze the support spring 322, and the distance between the support shaft 325 and the support shaft 325 gradually increases. The elastic force generated by the compression of the support spring 322 increases, which increases the contact force between the support shaft 325 and the wound cloth, and the winding linear speed increases, which can ensure that the support shaft 325 maintains a certain degree of squeezing the wound cloth to avoid loosening of the cloth.

[0038] like Fig. 9 As shown, an annular groove 326 arranged in an annular manner is provided at the end of the support shaft body 325, and a plurality of slits 327 are provided inside the support shaft body 325, and the slits 327 are connected with the annular groove 326. When the support shaft body 325 rotates, the slits 327 are kept connected with the annular groove 326 to realize uninterrupted air intake. A plurality of circumferentially distributed transverse grooves 328 are provided on the outside of the support shaft body 325, and inclined holes 329 are provided in the transverse grooves 328. The air blown out of the inclined holes 329 is used to smooth the fluff on the cloth in one direction. An air inlet hole 324 is provided on the outside of the sliding frame 321 on one side, and the air inlet hole 324 is connected with the annular groove 326. The gas moving inward from the air inlet 324 passes through the annular groove 326 and enters the slit 327, and is discharged from the inclined hole 329. The moving gas is also in a state of inclined motion. When the cloth is rolled up, the cloth will be clamped between the winding roller 36 and the support shaft 325. The cloth close to the support shaft 325 will be blown by the inclined gas, causing the fluff of the cloth to tilt in one direction. When the fluff is squeezed by the rolled cloth, it has unidirectionality, making the cloth more beautiful. In addition, when the cloth is squeezed by the support shaft 325, the transverse groove 328 will not be blocked, so that the gas can move from the transverse groove 328 to maintain the stability of the outward moving airflow.

[0039] An inner ball 320 is rotatably installed inside the support shaft 325. The support shaft 325 extends from one side of the inner ball 320. The support shaft 325 is used to squeeze the cloth. The inner ball 320 separates the cloth and the support shaft 325 to a certain extent. After the cloth contacts the inner ball 320, there is a gap around them, which can enable gas to move and avoid blockage.

[0040] The outer wall of the support shaft 325 is rough, and the length of the support shaft 325 is greater than the width of the cloth to be rolled up. The support shaft 325 can rotate as the cloth is rolled up to avoid sliding friction and damage to the cloth.

[0041] The working principle of the present invention is as follows: the winding roller 36 is sleeved between multiple groups of circumferentially distributed support parts 32, and the polygonal opening 37 at the end of the winding roller 36 cooperates with the polygonal shaft 35 of the winding motor 34, so that the winding motor 34 drives the winding roller 36 to rotate, and also limits the winding roller 36 to keep it horizontal, so that the cloth is wound up, and the wound cloth can be directly taken out of the winding roller 36 horizontally, which is convenient for direct taking and placing;

[0042] When the winding roller 36 is winding the cloth, the outer side of the wound cloth is supported by the support part 32, and as the diameter of the wound cloth increases, the support part 32 will squeeze the support spring 322 outward, so that the wound cloth is not loosened, and the winding roller 36 is clamped during winding to prevent the winding roller 36 from deviating during the rotation process and causing the cloth edge to roll up or wrinkle. In addition, the winding roller 36 is clamped during the winding process, so that the wound cloth can be more closely attached, ensuring that the cloth remains tight during the winding process to avoid gaps or looseness.

[0043] In addition, when the cloth is wound onto the winding roller 36, it is clamped by the wound cloth and the support portion 32. The clamped cloth is squeezed, which can prevent the cloth from being deformed due to uneven tension. The outer support portion 32 can provide a uniform squeezing force, so that the cloth is subjected to uniform tension during the winding process, thereby preventing the cloth from being deformed and the edges of the cloth from rolling up or wrinkling.

[0044] In addition, the air is transported from the air inlet 324 by the air pump, so that the air moves out from the inclined hole 329. In the process of the air moving outward, the cloth that is about to contact the support shaft body 325 is blown sideways, so that the fluff on the cloth is tilted to one side to a certain extent. In the subsequent cloth winding process, the fluff is squeezed, which makes it easy to shape the fluff on the cloth. The fluff is roughly shaped in one direction, which can improve the appearance of the cloth. Among them, the function of the inner ball 320 is to space the cloth and the support shaft body 325 to a certain extent, so that the cloth contacts the inner ball 320 and the support shaft body 325. At the same time, after the cloth contacts the inner ball 320, there is a gap around it, which can make the gas move and avoid blockage. The inner ball 320 can rotate. When the winding roller 36 is dragged out after winding, the inner ball 320 can be rotated under force to reduce the friction with the support shaft body 325, so as to facilitate the dragging out of the winding roller 36 after winding.
