Description

Technical Field

[0001] This utility model specifically relates to a microfiber fabric winding device. Background Technology

[0002] In the production and processing of microfiber fabric, winding is one of the key processes. A winding device is needed to neatly wind the continuously produced microfiber fabric for subsequent storage, transportation, and further processing. The core component of existing microfiber fabric winding devices is the winding roller. Traditional winding rollers often have fixed clamping structures or can only perform a single clamping function, which has significant technical defects: Firstly, when the clamping structure is fixed and protruding, the fabric is tightly adhered to the roller surface after winding, lacking a pre-reserved gap. This makes it difficult to directly unwrap the fabric along the roller's axial direction, and forced unwinding can easily cause edge wear and wrinkling of the microfiber fabric, affecting product quality. Secondly, some winding rollers' clamping structures cannot flexibly retract inward to loosen, requiring additional tools to loosen the fabric after winding. This operation is cumbersome and inefficient, failing to meet the needs of rapid unwinding in large-scale production. Utility Model Content

[0003] In view of the defects of the existing technology, the technical problem to be solved by this utility model is to provide a microfiber cloth winding device. A microfiber fabric winding device includes a winding roller, characterized in that: the winding roller includes a roller body and a clamping structure; one side of the roller body has an inwardly recessed mounting groove along its axial direction; the clamping structure is movably disposed within the mounting groove and can movably protrude outward from the outside of the roller body or be movably accommodated within the mounting groove; wherein, the clamping structure includes a slider and two clamping blocks; the mounting groove has symmetrical inclined surfaces on both sides, the distance between the two inclined surfaces being smaller on the outside and larger on the inside with the center of the roller body as the center; the two clamping blocks are symmetrically disposed on the slider and can move relatively closer or further apart; a first spring is provided between the two clamping blocks to drive the two clamping blocks to maintain a relatively far moving tendency; the slider is movably disposed within the mounting groove and can reciprocate towards the opening of the mounting groove; the movement of the slider causes the two clamping blocks to respectively abut against the inclined surfaces and move relatively closer; one end of the roller body is provided with a driving member that can drive the slider to move.

[0004] In one embodiment, the driving component includes a driving ring that is rotatably fitted onto one end of the roller body via a threaded engagement, a fixed shaft is provided at one end of the slider, an inclined groove is provided through one side of the driving ring, and the fixed shaft is movably disposed within the inclined groove.

[0005] In one embodiment, grooves are recessed on the inner sides of the two clamping blocks respectively, and the two ends of the first spring respectively abut against the grooves.

[0006] In one embodiment, a connecting shaft is provided at the center of one end of the roller body, the drive ring is threadedly fitted onto the connecting shaft, and a locking member is provided on the connecting shaft to lock the drive ring from rotating.

[0007] In one embodiment, the locking member includes a locking ring, a limiting groove is recessed inward along the axial direction on one side of the connecting shaft, the locking ring is movably sleeved on the connecting shaft, and a flange that can cooperate with the limiting groove extends on the inner side of the locking ring. A plurality of locking teeth are evenly distributed along the circumference on the outer side of the driving ring, and a plurality of locking grooves that can engage with the locking teeth are evenly distributed along the circumference on the inner side of the locking ring.

[0008] In one embodiment, the locking member further includes a second spring, and the connecting shaft has a protrusion. The second spring is sleeved on the connecting shaft and located between the protrusion and the locking ring. In summary, the advantages of this utility model over the prior art are: This invention utilizes the combination of a roller body and a movable clamping structure. When the clamping structure protrudes outward, it can reliably clamp the end of the microfiber fabric, ensuring that the fabric does not shift or slip during the winding process. After winding is completed, the clamping structure retracts inward to release the fabric, and a pre-reserved gap is formed between the fabric and the roller body after retraction. This completely solves the problem of the fabric being tightly attached to the roller body and difficult to remove in traditional winding rollers. The fabric can be quickly removed along the roller body axis, avoiding damage to the fabric during disassembly and improving the efficiency of winding and subsequent processes.

Detailed Implementation

[0010] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1 to 4The present invention preferably provides a microfiber fabric winding device, including a winding roller. The winding roller includes a roller body 1 and a clamping structure. One side of the roller body 1 has an inwardly recessed mounting groove 2 along its axial direction. The clamping structure is movably disposed within the mounting groove 2 and can movably protrude outward from the outside of the roller body 1 or be movably accommodated within the mounting groove 2. The clamping structure includes a slider 3 and two clamping blocks 4. The mounting groove 2 has symmetrical inclined surfaces 5 on both sides, and the distance between the two inclined surfaces 5 is approximately centered on the center of the roller body 1. The roller body 1 has a smaller outer diameter and a larger inner diameter. The two clamping blocks 4 are symmetrically arranged on the slider 3 and can move relatively closer or further apart. A first spring 6 is provided between the two clamping blocks 4. The first spring 6 drives the two clamping blocks 4 to maintain a relatively far movement tendency. The slider 3 is movably arranged in the mounting groove 2 and can reciprocate towards the opening of the mounting groove 2. The movement of the slider 3 causes the two clamping blocks 4 to respectively abut against the inclined surface 5 and move relatively closer. One end of the roller body 1 is provided with a driving component 7 that can drive the slider 3 to move.

[0011] Specifically, in the initial state, the clamping structure is located within the retracted mounting groove, and the two clamping blocks are relatively far apart. The operator inserts one end of the microfiber fabric to be wound into the opening of the mounting groove and places it between the two clamping blocks. The driving component drives the slider to move along the mounting groove towards the opening. Since the inclined surfaces on both sides of the mounting groove are set in a "smaller outside and larger inside" configuration (with the center of the roller as the center), during the movement of the slider, the two clamping blocks abut against the corresponding inclined surfaces respectively. The lateral squeezing force generated by the inclined surfaces overcomes the opening force of the first spring, pushing the two clamping blocks relatively close and protruding outward from the outside of the roller, thereby clamping the end of the microfiber fabric and ensuring that the fabric does not loosen during winding.

[0012] When the detachment or disassembly state is required, the drive component reverses and drives the slider to retract inward along the mounting groove. The two clamping blocks move with the slider and are released from the pressure of the inclined plane. The first spring recovers its deformation and releases its elastic force, driving the two clamping blocks to move away from each other and retract into the mounting groove. The clamping structure releases the microfiber cloth. At this time, a reserved gap is formed between the wound cloth and the roller surface, and the operator can directly disassemble and detach the cloth along the roller axis.

[0013] Furthermore, the driving component 7 includes a driving ring 8 that is rotatably sleeved on one end of the roller body 1 through a threaded engagement, a fixed shaft 9 is provided at one end of the slider 3, and a slanted groove 10 is provided through one side of the driving ring 8, with the fixed shaft 9 movably disposed within the slanted groove 10.

[0014] Specifically, the drive ring of the drive component is threadedly fitted onto one end of the roller body. When the drive ring is rotated, the threaded fit converts the circumferential rotation of the drive ring into linear movement along the axial direction of the roller body. The fixed shaft at one end of the slider is movably embedded in the inclined groove of the drive ring. When the drive ring moves axially, the inclined structure of the inclined groove generates a thrust on the fixed shaft, which in turn drives the slider to reciprocate along the mounting groove, thereby realizing the outward convex clamping or inward retraction release of the clamping structure.

[0015] Furthermore, there are corresponding recesses 11 on the inner sides of the two clamping blocks 4, and the two ends of the first spring 6 respectively abut against the grooves 11.

[0016] Specifically, the grooves on the inner sides of the two clamping blocks provide an installation reference for the first spring. The two ends of the first spring abut against the two grooves respectively, ensuring that the spring is fixed in its installation position. When the clamping blocks are squeezed closer to each other by the inclined plane, the first spring is compressed and stores elastic potential energy. When the clamping blocks are released from the inclined plane, the first spring releases elastic potential energy and applies a reverse thrust to the clamping blocks through the grooves, driving the two clamping blocks to maintain a relatively far movement tendency, ensuring the reset reliability of the clamping structure.

[0017] Furthermore, a connecting shaft 12 is provided at the center of one end of the roller body 1, and the drive ring 8 is threadedly fitted onto the connecting shaft 12. The connecting shaft 12 is provided with a locking member 13 that can lock the drive ring 8 from rotating.

[0018] Specifically, the drive ring is threaded onto the connecting shaft at one end of the roller body. When the drive ring is adjusted to the target position (clamping or retracted state), the locking component is activated and restricts the circumferential rotation of the drive ring. Since the drive ring and the connecting shaft are threaded, after the rotation of the drive ring is locked, its axial position remains fixed, thereby keeping the slider and clamping structure in their current state and preventing clamping failure due to loosening of the drive ring during the winding process.

[0019] Furthermore, the locking member 13 includes a locking ring 14, a limiting groove 15 is recessed inward along the axial direction on one side of the connecting shaft 12, the locking ring 14 is movably sleeved on the connecting shaft 12, and a flange 16 extends on the inner side of the locking ring 14 to cooperate with the limiting groove 15. A plurality of locking teeth 17 are evenly distributed along the circumference on the outer side of the driving ring 8, and a plurality of locking grooves that can engage with the locking teeth 17 are evenly distributed along the circumference on the inner side of the locking ring 14.

[0020] Specifically, the locking ring is movably sleeved on the connecting shaft, with its inner flange embedded in the limiting groove of the connecting shaft. The limiting groove restricts the circumferential rotation of the locking ring, allowing it to move only axially along the connecting shaft. The evenly distributed teeth on the outer side of the drive ring and the evenly distributed grooves on the inner side of the locking ring are mutually compatible. When the locking ring moves towards the drive ring, the grooves and teeth engage, and the mechanical engagement of the teeth restricts the circumferential rotation of the drive ring, achieving locking. To unlock, the locking ring is pulled axially along the connecting shaft, separating the grooves and teeth, allowing the drive ring to rotate freely. The locking ring and drive ring can be magnetically attracted to each other, keeping them in a tight fit, thus maintaining the engagement of the teeth and grooves.

[0021] Furthermore, the locking member 13 also includes a second spring 19, and the connecting shaft 12 is provided with a protrusion 20. The second spring 19 is sleeved on the connecting shaft 12 and located between the protrusion 20 and the locking ring 14.

[0022] Specifically, the second spring is sleeved on the connecting shaft, with its two ends abutting against the protrusion of the connecting shaft and the locking ring, respectively. In its natural state, the second spring is compressed and generates elastic thrust, pushing the locking ring to move along the connecting shaft axis toward the drive ring, so that the groove of the locking ring and the teeth of the drive ring are always engaged and locked. When unlocking is required, the operator pulls the locking ring away from the drive ring, compressing the second spring and separating the groove from the teeth. After unlocking, the locking ring is released, the second spring returns to its deformation and pushes the locking ring to reset, thus re-locking.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
