Description

Technical Field

[0001] The invention relates to the technical field of cloth winding, in particular to a grey cloth positioning and winding operation device. Background Art

[0002] Grey cloth refers to cloth that has been woven but has not yet been dyed, printed or otherwise finished. After weaving is completed, in order to facilitate the storage, transportation and subsequent processing (such as dyeing, printing, etc.) of the grey cloth, it needs to be wound into a tube of a certain thickness as required.

[0003] During the winding process, the uniformity and neatness of the grey fabric winding will be affected by the quality of the grey fabric surface and the tension of the grey fabric. When there are wrinkles on the surface of the grey fabric, it may lead to uneven winding during the winding process, and the original slight wrinkles may become more obvious and difficult to remove due to pressure during winding; when the tension of the grey fabric winding is low, it is easier to have the problem of winding slack, and too high tension may cause the grey fabric to be over-stretched and cause additional deformation.

[0020] 5. The flattening mechanism adopted by the present invention has the functions of clamping and limiting the base fabric up and down, leveling it, smoothing it from the middle to both sides in the horizontal direction, and clamping and fixing it on both the front and back sides.

It is connected through a pulley mechanism (the pulley mechanism is not shown in the figure), in which one of the cylinders 23 is connected to an external driving source; the side end clamping group includes an upper rotating shaft 24 which is slidably installed between the frames 20 and arranged alternately with the roller group, a lower fixed shaft 25 is arranged below the upper rotating shaft 24, and the lower fixed shaft 25 is fixedly installed between the frames 20, and clamping rollers 26 located between the frames 20 and symmetrically arranged are rotatably installed on the upper rotating shaft 24 and the corresponding lower fixed shaft 25, and the axis of the clamping roller 26 is parallel to the axis of the upper rotating shaft 24, and a linkage part 27 for making several upper rotating shafts 24 slide synchronously is provided on the frame 20. The grey cloth passes from right to left in sequence between two conveying rollers 21 arranged symmetrically in the upper and lower parts of the roller group. The spiral protrusion on the cylinder 23 contacts the lower end surface of the grey cloth, and the grey cloth passes between the corresponding two clamping rollers 26 on the corresponding upper rotating shaft 24 and the lower fixed shaft 25. In the initial state, the corresponding two clamping rollers 26 do not clamp the side ends of the grey cloth. Then the grey cloth passes between the tensioning shafts 31, and finally the end of the grey cloth is fixed on the winding core fixed by the three-flower chuck. The positioning plate 22 on the conveying roller 21 can implement preliminary positioning of the grey cloth to prevent the grey cloth from being skewed and causing the grey cloth to be rolled up evenly, which directly affects the quality of the grey cloth.

[0034] See also Figure 1 , Figure 7 , Figure 8 and Fig. 9The linkage part 27 includes a C-shaped plate 270 installed at the end of the upper rotating shaft 24. The two vertical sections of the C-shaped plate 270 are telescopic structures and the telescopic sections are slidably connected to the corresponding guide rods. A toothed plate 271 is installed at the lower end of the C-shaped plate 270 through an inverted L plate. The toothed plate 271 is slidably connected to the frame 20. One side of the toothed plate 271 is meshedly connected to a gear 272 rotatably connected to the frame 20. The plurality of gears 272 are controlled by a transmission member to rotate synchronously. The upper end of the frame 20 is divided into an inclined section 1, an inclined section 2, and a horizontal section connected between the inclined section 1 and the inclined section 2. The inclined section 1 and the inclined section 2 are connected to each other. Segment 2 and the horizontal segment form an inverted U-shaped structure, and the inclined segment 1, the inclined segment 2 and the horizontal segment each correspond to three gears 272, and the three gears 272 form a group, two of the gears 272 in the same group are meshed, and the transmission member includes a belt 1 273. One of the two meshed gears 272 and the remaining gear 272 in the same group are connected by a belt 1 273. The two non-meshing gears 272 corresponding to the horizontal segment are connected by a belt 2 to the other gears 272 with the same rotation direction, and any gear 272 is connected to an external drive source.

[0035] After the wiring operation of the grey cloth is completed, the cylinder 23 is driven by the external driving source connected to the cylinder 23 and the pulley mechanism to rotate. Since the thread directions of the two sections of the spiral protrusions on the cylinder 23 are opposite, the two rotating spiral protrusions can cooperate to generate a stroking force from the middle to both sides of the grey cloth. The stroking force is used to improve the flatness of the grey cloth, so as to ensure that the clamping roller 26 clamps the side ends of the grey cloth in a flat state, and ensures that the grey cloth is conveyed and wound flatly and stably. Then, the cylinder 23 is stopped from rotating, and the gears 272 are rotated synchronously by the cooperation of the external driving source connected to the gear 272 and the belt 1 273 and the belt 2. The rotation directions of the two meshing gears 272 in the same group are opposite, and the other gear 272 rotates in the same direction as one of the two meshing gears 272. The rotating gears 272 are meshed with the toothed plates 271, and all the toothed plates 271 slide downward. The toothed plates 271 drive the corresponding L-plates to drive the U-shaped plates 270 to move downward, and the vertical section of the U-shaped plates 270 is elongated, and the non-retractable part of the U-shaped plates 270 drives the corresponding upper rotating shaft 24 to move downward, and the upper rotating shaft 24 drives the corresponding clamping rollers 26 to move downward, and the clamping rollers 26 on the upper rotating shaft 24 and the corresponding lower fixed shaft 25 cooperate to clamp the ends of the grey cloth, but the grey cloth between the clamping rollers 26 can still be transported from right to left in real time with the cooperation of the winding end 1 and the corresponding unwinding equipment. After the clamping roller 26 clamps the side end of the grey cloth, the motor drives the three-claw chuck and the winding core to rotate synchronously to wind the grey cloth, and the corresponding unwinding device unwinds synchronously. At the same time, the cylinder 23 continues to rotate. During the winding of the grey cloth, the tensioning shaft 31 and the conveying roller 21 rotate synchronously with the conveying of the grey cloth. The upper and lower corresponding clamping rollers 26 are used to clamp the side ends of the grey cloth to achieve secondary positioning of the grey cloth, avoid position deviation of the grey cloth, improve the neatness and uniformity of the grey cloth winding, and thus improve the winding quality of the grey cloth. During the winding, the spiral protrusions on the cylinder 23 can smooth the grey cloth from the middle to both sides in real time, improving the winding quality of the grey cloth.

[0036] As the winding operation proceeds, the winding thickness of the grey cloth on the winding core increases. To avoid excessive tension of the grey cloth, the electric push rod 32 can gradually and slowly or intermittently push the connecting block 33 to move the slide column to the upper left along the inclined groove, and then move the tensioning shaft 31 along the inclined groove. In this way, the tensioning degree of the grey cloth is adjusted according to the winding thickness of the grey cloth, and the grey cloth is prevented from being stretched and deformed due to excessive tension while ensuring that the grey cloth is tightly wound.

[0037] See also Figure 1 , Figure 3 , Figure 5 , Figure 7 , Figure 8 and Fig. 9A smoothing group 28 is provided between the upper rotating shaft 24 and the corresponding lower fixed shaft 25 for smoothing the grey cloth from the middle to both sides before the clamping rollers 26 clamp the grey cloth. The stroking group 28 includes a bidirectional lead screw 280 located above the upper rotating shaft 24 and rotatably installed between the frames 20. The bidirectional lead screw 280 is provided with two threaded sections with opposite thread directions, and inner sleeves 281 are threadedly installed on the two threaded sections. An outer sleeve 281 is rotatably sleeved on the outer side of the inner sleeve 281, and an inverted L-shaped frame 282 is symmetrically installed on the outer side of the outer sleeve, and a stroking roller 283 located between the corresponding upper rotating shaft 24 and the lower fixed shaft 25 is rotatably installed between the lower ends of the inverted L-shaped frame 282. A guide rod fixedly connected to the frame 20 is slidably installed on the upper end of the inverted L-shaped frame, and a plurality of bidirectional lead screws 280 are connected by synchronous transmission members 284; the synchronous transmission member 284 is composed of a sprocket mounted on the end of the bidirectional lead screw 280 and a chain belt matched with the sprocket transmission, and one end of one of the bidirectional lead screws 280 is fixedly connected to the conveying shaft of a transmission motor installed on the frame 20 through a motor seat.

[0038] Before the clamping roller 26 clamps the side end of the grey cloth, while the cylinder 23 rotates, the transmission motor, chain belt and sprocket cooperate to make several bidirectional lead screws 280 rotate synchronously. The rotation of the bidirectional lead screw 280 makes the inner sleeve 281 thereon rotate and move from the middle part of the grey cloth to the side end of the grey cloth. The inner sleeve 281 drives the outer sleeve and the inverted L-shaped frame 282 to move synchronously. Limited by the guide rod, the inverted L-shaped frame 282 and the outer sleeve only move along the axial direction of the bidirectional lead screw 280. The inverted L-shaped frame 282 drives the caressing roller 283 to move. The caressing roller 283 moves along the upper end surface of the grey cloth. The caressing roller 283 and the lower fixed shaft 25 cooperate to implement a caressing process on the grey cloth from the middle part to both sides, so as to further improve the flatness of the grey cloth. After the caressing roller 283 passes over the side end of the grey cloth, the upper rotating shaft 24 moves downward again.

[0039] See also Figure 1 , Figure 2 , Figure 5 and Figure 6The winding end 1 is provided with a conforming group 10 for implementing circumferential elastic pressing, and the conforming group 10 includes a plurality of pressing plates 11 equidistantly distributed along the circumference of the core. The number of the pressing plates 11 is three and they are distributed within a range of 180 degrees. A guide column 12 is installed at one end of the pressing plate 11 away from the center of the core. The guide columns 12 slide together and are installed through an open ring plate 13. The open ring plate 13 is arranged between the brackets. The guide column 12 is connected to the inner ring wall of the open ring plate 13 by a spring sleeved thereon, and the open end of the open ring plate 13 faces to the right. The open ring plate 13 is provided with a distance limiting member 14 for limiting the sliding distance of the guide column 12. The distance limiting member 14 includes a horizontal T-shaped plate 140 installed at the end of the guide column 12 away from the corresponding pressing plate 11. The horizontal T-shaped plate 140 is slidably installed in a return frame 141. The return frame 141 is installed on the outer wall of the open ring plate 13. The side end of the return frame 141 is provided with a plurality of plug holes arranged equidistantly along the radial direction of the open ring plate 13, and a distance limiting rod 142 is inserted into any one of the plug holes. The horizontal T-shaped plate 140 is located between the corresponding distance limiting plate and the outer wall of the open ring plate 13. During the process of rolling the grey cloth, the pressing plate 11 can always be pressed on the surface of the grey cloth with the cooperation of the guide column 12 and the spring, and the rolled grey cloth is subjected to circumferential pressing and limiting, so as to further ensure the compactness of the rolled grey cloth. As the thickness of the rolled grey cloth increases, the pressing plate 11 is subjected to a driving force directed to the outside of the winding core, and the pressing plate 11 drives the guide column 12 to move radially along the open ring plate 13 and compress the spring. When the guide column 12 moves, it will drive the horizontal T-shaped plate 140 to move synchronously. When the horizontal T-shaped plate 140 is blocked by the distance limiting rod 142 and cannot move further, the rolled grey cloth reaches the required thickness. Before the grey cloth is cut and the winding core is removed, the pressing plate 11 can implement stable circumferential pressing and limiting on the grey cloth roll to prevent the rolled grey cloth from loosening. By adjusting the position of the distance limiting rod 142, the pressing plate 11 can adapt to the pressing and limiting of grey cloth rolls with different rolled thicknesses.

[0040] See also Figure 6 A vertical plate 15 is installed on the left end of the bracket, wherein the front end of the fixed bracket is fixedly installed with a track rod 16 symmetrically installed up and down, the open ring plate 13 is fixedly installed between the track rods 16, and the left end of the vertical plate 15 on the sliding bracket is provided with a through hole corresponding to the track rod 16. After the winding core is fixed by the three-jaw chuck, the track rod 16 is inserted into the corresponding through hole. The cooperation between the track rod 16 and the through hole is utilized to improve the overall stability and connection strength of the winding end 1, thereby facilitating the improvement of the quality of the grey cloth winding.
