Description

Technical Field

[0001] This utility model relates to the field of fabric spreading machines, specifically a fabric bucket power roller with a rubber sleeve. Background Technology

[0002] A fabric spreading machine, also known as a fabric laying machine, extension machine, or fabric spreading machine, is used to lay fabric layer by layer on a spreading table according to process requirements. These process requirements include the spreading length, the number of spreading layers, alignment of the fabric ends between layers, alignment of the selvage edges, and a flat (tension-free) fabric surface. As is well known in the industry, fabric spreading and cutting play crucial roles in garment production. Only well-formed cut pieces can yield finished garments that meet specifications; conversely, if the cut pieces are irregular, even the best sewing equipment and sewing workers cannot produce high-quality garments. Fabric spreading is the preceding step to fabric cutting, and its quality affects the entire production process.

[0003] For example, our company's patent with authorization announcement number CN206126421U discloses a fabric spreading machine suitable for knitted thin fabrics. It includes a frame, a fabric hopper, a fabric unwinding wheel, a fabric unwinding groove, a front column roller, a head pressing device, and a feeding wheel. The feature is that an arc-shaped fabric spreading tube with an upward arch in the middle is provided in front of the fabric unwinding wheel. An inclined slide plate is provided above the fabric unwinding wheel and the fabric unwinding groove. The fabric spreading tube, the slide plate, and the front column roller are arranged from high to low. The head pressing device includes a head seat. The pressing wheel is fixed on a pressing rod. The pressing rod installed on the head seat can be adjusted in angle through the slot at the tail. The pressing wheel presses the fabric towards the feeding wheel from the inside.

[0004] In the aforementioned patent, the fabric moves from top to bottom without passing through the unwinding wheel and unwinding groove. Instead, the fabric passes through the spreading tube and transition plate, allowing it to extend to both sides, thus effectively spreading the fabric and facilitating the fabric spreading action. This invention is applicable to the processing of knitted thin fabrics; however, the aforementioned patent has a drawback: typically, a power roller is present in the unwinding groove to drive the fabric roll to rotate, thereby assisting in the spreading of the fabric. Generally, this power roller is a smooth shaft, and in actual use, the smooth shaft is prone to slippage when in contact with relatively smooth fabric, resulting in poor performance.

[0005] Therefore, it is necessary to improve such a structure to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of this invention is to provide a cloth bucket power roller with a rubber sleeve to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A cloth bucket power roller with a rubber sleeve includes a roller shaft, a roller, and a rubber sleeve. The two ends of the roller are fixedly connected to the roller shaft via end caps. The end caps are fixed to the roller shaft via shoulders and retaining springs, and the two symmetrically arranged end caps further fix the roller. The outer wall of the roller has several evenly spaced slots. The inner wall of the rubber sleeve has several evenly spaced locking blocks, and the rubber sleeve and locking blocks are integrally formed. Each slot and locking block corresponds to a specific slot. The rubber sleeve is fitted onto the outer wall of the roller, and the locking blocks are engaged within the slots. Each slot includes a V-shaped guide opening, and the bottom of the guide opening has a circular locking portion. The guide opening and the locking portion overlap, such that the width of the opening of the locking portion is between the radius of the locking portion and two-thirds of its radius. The locking blocks are fitted into the slots, and each locking block also includes a V-shaped portion and a circular portion.

[0009] Furthermore, the roller has openings at both ends, and the inner wall of the opening at one end of the roller has an abutment stepped groove, with the inner end of the end abutting against the end of the abutment stepped groove; at the same time, a through hole for the roller shaft to pass through is opened at the center of the end; a shoulder is provided on the roller shaft near the inner side of the through hole, and a retaining spring groove is provided on the roller shaft near the outer side of the through hole, with a retaining spring engaged in the retaining spring groove, and the inner side of the retaining spring abutting against the end.

[0010] Furthermore, the roller shaft has square ends for fixing to the transmission components.

[0011] Furthermore, a limiting ring is provided at the outer end of the end, wherein the limiting ring is grounded with the end of the rubber sleeve, thereby preventing the rubber sleeve from coming off from both ends of the roller.

[0012] Furthermore, the outer diameter of the limiting ring should be greater than the outer diameter of the roller and less than the outer diameter of the rubber sleeve.

[0013] Furthermore, the surface of the rubber sheath may also be covered with adhesive-backed fleece.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model uses a rubber sleeve to cover the surface of the roller, which can increase the friction between the power roller and the fabric, thereby preventing slippage when the power roller comes into contact with the fabric.

[0016] At the same time, the rubber sleeve is fixed by the cooperation of the slot and the snap block to prevent the rubber sleeve from slipping relative to the roller, and it is also convenient to replace the rubber sleeve after it ages.

[0017] Furthermore, compared to using glue to fix the rubber sleeve, this solution will not leave any glue residue on the roller surface after replacement. Attached Figure Description

Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0026] Please see Figure 1-7 The cloth bucket power roller with a rubber sleeve includes a roller shaft 1, a roller 2, and a rubber sleeve 3.

[0027] The two ends of the roller 2 are fixedly connected to the roller shaft 1 through the end head 4;

[0028] Specifically, the roller 2 has openings at both ends, and the inner wall of the opening at the end of the roller 2 is provided with an abutment stepped groove 201. The inner end of the end 4 abuts against the end of the abutment stepped groove 201. At the same time, a through hole 401 for the roller shaft 1 to pass through is opened at the center of the end 4. The roller shaft 1 is provided with a shoulder 101 near the inner side of the through hole 401, and a retaining spring groove 102 is provided near the outer side of the through hole 401. A retaining spring 103 is engaged in the retaining spring groove 102, and the inner side of the retaining spring 103 abuts against the end 4.

[0029] The end 4 of this utility model is fixed to the roller shaft 1 by a shoulder and a retaining spring, and the two symmetrically arranged end 4 then fix the roller 2.

[0030] In this design, square heads 104 are provided at both ends of the roller 1 for fixing to the transmission components.

[0031] The outer side wall of the roller 2 is provided with a plurality of slots 5 evenly spaced apart;

[0032] The inner wall of the rubber sleeve 3 is provided with a plurality of snap-fit ​​blocks 301 evenly spaced, and the rubber sleeve 3 and the snap-fit ​​blocks 301 are integrally formed.

[0033] The slot 5 and the snap-fit ​​block 301 are set in a one-to-one correspondence. The rubber sleeve 3 is sleeved on the outer wall of the roller 2, and the snap-fit ​​block 301 is snapped in the slot 5.

[0034] The slot 5 includes a guide opening 501 with a V-shaped cross-section, and a snap-fit ​​part 502 with a circular cross-section is provided at the bottom of the guide opening 501. Part of the guide opening 501 and part of the snap-fit ​​part 502 overlap, such that the width of the opening of the snap-fit ​​part 502 is between the radius of the snap-fit ​​part and two-thirds of the radius.

[0035] Meanwhile, the snap-fit ​​block 301 is configured to cooperate with the snap-fit ​​slot 5. The snap-fit ​​block 301 also includes a V-shaped portion 302 and a circular portion 303.

[0036] During assembly, the circular portion 303 of the snap-fit ​​block 301 enters the opening of the snap-fit ​​portion 502 through the guide port 501, and then the circular portion 303 is squeezed into the snap-fit ​​portion 502. At this time, the V-shaped portion 302 is located inside the guide port 501.

[0037] In this scheme, a limiting ring 402 is also provided at the outer end of the end 4, wherein the limiting ring 402 is grounded with the end of the rubber sleeve 3, thereby preventing the rubber sleeve from coming off from both ends of the roller 2; the outer diameter of the limiting ring 402 should be greater than the outer diameter of the roller 2 and smaller than the outer diameter of the rubber sleeve.

[0038] When using this utility model, the rubber sleeve 3 is put on the roller 2. At this time, the snap-fit ​​block 301 has not been fully pressed into the slot 5. After the rubber sleeve 3 is put on, the snap-fit ​​block 301 is pressed from the outside of the rubber sleeve 3 to fully press the snap-fit ​​block into the slot 5. Then the end is installed on both ends of the roller 2, and finally the roller shaft is fixed by snap-fit ​​spring.

[0039] In some embodiments of this solution, the surface of the rubber sleeve 3 may also be adhered with adhesive-backed fleece. This can be used to prevent static electricity generated by friction between the rubber and certain fabrics.
