A fabric unwinding and edge stripping device

Abstract

The present invention provides a fabric unwinding and edge stripping device, comprising two symmetrically structured edge stripping device bodies, symmetrically mounted on either side of a fabric unwinding frame and provided with guide slots; the side portions of the fabric are inserted into the guide slots. The guide slots not only guide the fabric during operation, preventing it from tilting during operation, but also prevent an edge expander on the fabric from being blocked by the slot walls when it reaches the slots and falling off the fabric, thereby preventing it from affecting fabric cleaning and drying.

Description

Technical Field

[0001] The invention relates to the technical field of fabric production equipment, in particular to a fabric unwinding and edge stripping device. Background Art

[0002] After weaving, fabrics are usually rolled up for storage. During the weaving process, the fabric will carry some loose hair and some small particles. If these small particles are not cleaned, they will affect the quality of the fabric during subsequent processing, such as printing and dyeing. On the other hand, the particles that are easily shed during the printing and dyeing process will enter the dye solution, causing a significant impact on the dye solution.

[0003] Therefore, the woven fabric needs to be cleaned and dried before it can be processed. When the fabric is cleaned and dried, it needs to be unwound first. In order to improve the cleaning effect of the fabric, the fabric must be kept straight and the side edges cannot curl. Therefore, when the fabric is unwound, an expander is clamped on the side of the fabric. Figure 14 As shown, the edge expander is made of steel springs or bamboo pieces, and is fixed to the side of the fabric in a clamping manner through its elasticity.

[0004] Washing and drying the edge expander along with the fabric not only affects fabric quality but can also damage the equipment. Therefore, the edge expander must be removed before entering the cleaning process. Currently, this removal is typically done manually, which is labor-intensive, as the fabric moves rapidly, and the edge expander can cause cuts to the hands. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to solve the technical problem that the traditional manual removal process of the edge expander on the unwinding fabric has high labor intensity and high risk.

[0006] The invention provides a fabric unwinding and edge stripping device, comprising two edge stripping device bodies with symmetrical structures, which are symmetrically installed on both sides of a fabric unwinding frame and provided with guide grooves; the fabric side parts are inserted into the guide grooves.

[0007] The guide groove is not only used to guide the fabric so that the fabric will not tilt during operation, but also when the edge expander on the fabric runs into the guide groove, it will be blocked by the guide groove wall and fall off the fabric, thereby avoiding affecting the cleaning and drying of the fabric.

[0008] Since fabric widths vary, in order to adapt the present invention to fabrics of different widths, the distance between the edge stripper bodies is adjustable. Specifically, a horizontally arranged bidirectional screw rod is provided on the frame, and the edge stripper bodies are respectively mounted on screw rod nuts on both sides of the bidirectional screw rod.

[0009] Since the position of the conventional stripper body is unstable when the spacing is adjusted, further improvements are made to solve this problem. Specifically, a horizontally arranged rectangular tube is provided in the middle position of the frame, a sleeve is sleeved on the rectangular tube, and the stripper body is fixedly connected to the sleeve.

[0010] Since the grease on the bidirectional screw rod easily contaminates the fabric, this problem is further improved and solved. Specifically, the bidirectional screw rod and the screw rod nut are hidden in the rectangular tube;

[0011] A notch is provided on the lower side of the rectangular tube, and the connecting bolt passes through the sleeve and the notch in sequence and is threadedly connected with the screw nut.

[0012] The specific structure of the guide groove is as follows: the edge stripper body includes two nylon blocks that are symmetrically arranged and elastically connected, and the gap between the nylon blocks constitutes the guide groove.

[0013] Since the fabric is easy to shake in the guide groove, which will affect the stability of the fabric operation, further improvements are made to solve this problem. Specifically, the edge stripper body also includes a plate frame, a plurality of U-shaped grooves are provided at the bottom of the plate frame, and the nylon block is connected to the plate frame through the U-shaped groove; the nylon block is connected to the plate frame through a spring, thereby exerting pressure on the fabric.

[0014] Since fabrics vary in thickness, to adapt the present invention to fabrics of varying thicknesses, a screw is provided on the nylon block in this embodiment. The screw passes through the plate frame, and the spring is sleeved onto the screw. The screw is also threadedly connected to an adjustment nut for adjusting the length of the screw extending from the plate frame. The adjustment nut is mounted on the outside of the plate frame, and by turning the adjustment nut, the spacing between the nylon blocks can be adjusted.

[0015] Since the spring is made of steel and is directly connected to the nylon block, it will cause damage to the nylon block, so further improvements are made to solve this problem. Specifically, the inner end of the screw is integrally connected with a baffle and a connecting rod, and the connecting rod is integrally injection-molded with the nylon block. The two ends of the spring respectively abut against the baffle and the plate frame.

[0016] Furthermore, the nylon blocks are arranged obliquely and tilted toward the direction of fabric movement. In this way, the friction of the nylon blocks on the fabric will form a force component toward the outside of the fabric, which will form a tensile force on the fabric to both sides, making the fabric smoother during movement and less likely to curl.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0034] Example 1:

[0035] like Figure 1 and Figure 4 As shown, the present invention is a fabric unwinding and edge stripping device, comprising an edge stripping device body 1 symmetrically mounted on both sides of a fabric unwinding frame 2.

[0036] like Figure 9 、 Figure 11 and Figure 13 As shown, the edge stripper body 1 includes a frame 12, which is a frame with an open top and a through slot at the bottom. The opposite end of the frame 12 is also open. Two symmetrically arranged nylon blocks 11 are installed in the frame 12, with a gap between the two nylon blocks 11 to form a guide slot. Figure 2 As shown, the side of the fabric is inserted into the guide groove.

[0037] The stripper body 1 is provided with guide rollers on both the upper and lower sides, and the fabric passes through the upper guide roller, the guide groove and the lower guide roller in sequence. The upper guide roller guides the fabric into the guide groove.

[0038] The guide groove is not only used to guide the fabric to avoid tilting during operation, but also when the edge expander on the fabric runs to the guide groove, it will be blocked by the nylon block 11 and fall off the fabric, thereby avoiding affecting the cleaning and drying of the fabric.

[0039] Example 2:

[0040] Compared with the first embodiment, the difference is: Figure 7 and Figure 8 As shown, a horizontally arranged bidirectional screw 3 is mounted on the frame 2, with its two ends rotatably connected via bearings. A handwheel is mounted on one end of the bidirectional screw 3. The edge stripper body 1 is mounted on screw nuts 4 on either side of the bidirectional screw 3. By turning the handwheel, the spacing of the edge stripper bodies 1 can be adjusted, making the present invention suitable for fabrics of varying widths.

[0041] Example 3:

[0042] Compared to the second embodiment, the following differences are noted: a horizontally arranged rectangular tube 21 is positioned in the middle of the frame 2, with fixed bases on either side. Cover plates are bolted to the bases, securing the rectangular tube 21 by clamping the bases and cover plates together. A rectangular sleeve 22 is sleeved onto the rectangular tube 21, which slides on the rectangular tube 11. The frame 12 is fixedly connected to the sleeve 22. The sleeve 22 and rectangular tube 21 not only stabilize the position of the edge stripper body 1 but also guide its movement.

[0043] Example 4:

[0044] Compared with the third embodiment, the difference is: Figure 5 and Figure 6As shown, the bidirectional screw 3 and screw nut 4 are both hidden in the rectangular tube 21. The rectangular tube 21 has a notch 23 on its underside, and a connecting bolt 24 passes through the sleeve 22 and the notch 23 in sequence and is threadedly connected to the screw nut 4. This arrangement prevents the grease on the bidirectional screw 3 from contaminating the fabric.

[0045] Embodiment 5:

[0046] Compared with the first embodiment, the difference is: Figure 10 As shown, the bottom of the frame 12 is provided with multiple U-shaped slots 13 that connect to the through slots. The U-shaped slots 13 are perpendicular to the through slots. Bolts pass sequentially through the U-shaped slots 13 and the nylon block 11. Nuts secure the nylon block 11 in place, preventing it from bouncing during fabric movement. The U-shaped slots 13 allow for adjustable positioning of the nylon block 11 and provide the necessary displacement space for its elasticity. The nylon block 11 is connected to the frame 12 via springs 18, which apply pressure to the fabric, preventing it from wobbling within the guide slots and affecting its stability.

[0047] Example 6:

[0048] Compared with the fifth embodiment, the present invention differs in that a screw 14 is provided on the nylon block 11, which passes through the plate frame 12. A spring 18 is sleeved on the screw 14, with its ends respectively abutting the nylon block 11 and the plate frame 12. An adjusting nut 15 is also threadedly connected to the screw 14 for adjusting the length of the screw 14 extending from the plate frame 12. The adjusting nut 15 is mounted on the outside of the plate frame 12. By turning the adjusting nut 15, the spacing between the nylon blocks 11 can be adjusted, thereby making the present invention suitable for fabrics of varying thicknesses.

[0049] Embodiment seven:

[0050] Compared with the sixth embodiment, the difference is: Figure 12 As shown, the inner end of the screw 14 is also integrally connected with a baffle 16 and a connecting rod 17, which is integrally injection-molded with the nylon block 11. The two ends of the spring 18 respectively abut against the baffle 16 and the plate frame 12. This arrangement can avoid the steel spring 18 being directly connected to the nylon block 11 and causing damage to the nylon block 11.

[0051] Embodiment 8:

[0052] Compared with the first embodiment, the difference is: Figure 3 As shown, the nylon block 11 is arranged obliquely and tilted toward the direction of fabric movement. In this way, the friction of the nylon block 11 on the fabric will form a component force toward the outside of the fabric, which constitutes a tensile force on the fabric to both sides, thereby making the fabric smoother during movement and less likely to curl.

[0053] With the above-described preferred embodiments of the present invention as a guide, and with reference to the above description, relevant personnel are fully capable of making various changes and modifications without departing from the technical scope of this invention. The technical scope of this invention is not limited to the contents of the specification and must be determined according to the scope of the claims.
