Description

Technical Field

[0001] The present invention belongs to the technical field of width expanding rollers, and particularly relates to a novel width expanding roller, a processing method of the novel width expanding roller, and a dyeing and finishing device. Background Art

[0002] The textile industry is a traditional pillar industry of China's national economy. As a major textile country in the world, the domestic textile industry in China shows an overall continuous growth trend. Therefore, there is still a large demand for various equipment used in the textile industry. In the process of textile production, such as textile, printing and dyeing, film manufacturing, and printing processes, width expanding rollers are required to unfold, flatten, and remove wrinkles from fabrics. The width expanding roller mainly provides a thrust to the fabric on both sides of the roller through the width expanding wires wound around the roller body, so as to achieve the effect of spreading the fabric. The width expanding wires are mostly round wires or semi-circular wires. Round wires or semi-circular wires have a certain spreading effect on hard fabrics. However, due to the need to ensure the conduction effect, the pitch of the round or semi-circular width expanding wires is generally relatively large. When used for expanding light fabrics, the light fabrics are prone to deformation on the width expanding roller and thus generate wrinkles. Therefore, they are not suitable for light and soft fabrics. To solve this problem, width expanding flat wires suitable for light fabrics have gradually emerged in the prior art. However, like round wires or semi-circular wires, the wire heads of the width expanding flat wires are prone to scratching the fabric.

[0003] The width of the width expanding flat wire is much larger than that of the round wire or semi-circular wire. Therefore, it is not suitable to hide the wire head by drilling holes in the roller body. The utility model patent with the patent number CN202023317482.3 and the name of a width expanding wire and a spreading roller discloses that grooves are opened on the spreading roller so that the wire heads of the width expanding wires are located in the grooves, and a protective sleeve is sleeved outside the grooves. The protective sleeve can wrap the sharp wire heads inside the protective sleeve. The protective sleeve itself is smooth, and the fabric will not be damaged when contacting it, playing a protective role for the fabric. However, in addition to the grooves affecting the strength of the roller body, sleeving the protective sleeve outside the grooves will cover part of the width expanding wires, affecting the spreading effect. Summary of the Invention

[0004] To solve the drawbacks of the above-mentioned prior art, the present invention discloses a novel width expanding roller, which adopts the following technical solutions:

[0005] A novel width expanding roller includes a roller body. The roller body is provided with a first width expanding wire and a second width expanding wire with opposite winding directions. One end of the first width expanding wire close to the second width expanding wire is a first wire head, and one end of the second width expanding wire close to the first width expanding wire is a second wire head.

[0010] Further, when the second support surface and the fourth support surface are arc surfaces, the arc length from the top end to the bottom end of the second support surface is 0-40 mm, preferably 10-30 mm; the arc length from the top end to the bottom end of the fourth support surface is 0-40 mm, preferably 10-30 mm.

[0011] Further, the heights of the first spreading filament and the second spreading filament are 1-20 mm, preferably 2-10 mm; the widths of the third support surface and the fifth support surface are 0-40 mm, preferably 2-20 mm; one end of the first spreading surface and the second support surface close to the roller surface is connected through a first mounting surface, one end of the second spreading surface and the fourth support surface close to the roller surface is connected through a second mounting surface, and the widths of the first mounting surface and the second mounting surface are 1-50 mm, preferably 5-30 mm.

[0013] The present invention also discloses a processing method for a new type of width expanding roller, which includes the following steps: winding the first width expanding wire and the second width expanding wire from the middle of the roller body to the end of the roller body in sequence, and fixing the first wire head and the second wire head at preset positions on the surface of the roller body before winding; covering the connecting piece on the roller surface between the first width expanding wire and the second width expanding wire, and connecting the first wire head and the second wire head to the connecting piece.

Detailed implementation mode

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0027] Embodiment 1

[0028] As Figures 1-7 shown, this embodiment discloses a novel width - expanding roller, including a roller body 1. The roller body 1 is provided with a first width - expanding wire 2 and a second width - expanding wire 3 with opposite winding directions. One end of the first width - expanding wire 2 close to the second width - expanding wire 3 is the first wire head, and one end of the second width - expanding wire 3 close to the first width - expanding wire 2 is the second wire head; the first width - expanding wire 2 extends along the roller surface in the first direction from the first wire head, and the second width - expanding wire 3 extends along the roller surface in the opposite direction of the first direction from the second wire head; a connecting piece 4 is arranged between the first width - expanding wire 2 and the second width - expanding wire 3, and the connecting piece 4 covers the roller surface between the first width - expanding wire 2 and the second width - expanding wire 3, and the first wire head and the second wire head are connected to the connecting piece 4. By arranging the connecting piece 4 between the first width - expanding wire 2 and the second width - expanding wire 3, the roller surface between the first width - expanding wire 2 and the second width - expanding wire 3 is filled, so that there is no depression between the first width - expanding wire 2 and the second width - expanding wire 3, avoiding the deformation and wrinkling of lightweight fabrics in the middle of the width - expanding roller due to lack of support; by connecting the first wire head and the second wire head to the connecting piece 4, the scratching of the fabric by the exposed first wire head and second wire head is avoided.

[0029] The connecting piece 4 in this embodiment is composed of one, two or more supporting parts. The number of supporting parts is the same as the number of the first width - expanding wire and the second width - expanding wire. The first wire head of one first width - expanding wire and the second wire head of one second width - expanding wire are connected to one supporting part of the connecting piece. As Figure 3 shown, the supporting part includes a first end 41 and a second end 42, and the width of the supporting part gradually decreases from the first end 41 to the second end 42. When the connecting piece 4 is composed of one supporting part, as Figure 2 shown ( Figure 2 is the front view of the connecting piece 4, and the dotted line is the part blocked), the first end 41 and the second end 42 of the supporting part are connected to form a ring; when the connecting piece 4 includes two or more supporting parts, as Figure 4As shown, the support parts are connected end to end to form a ring. Here, the end-to-end connection means that the first end 41 of the support part is connected to the second end 42 of the adjacent support part. The depression between the first spreading wire 2 and the second spreading wire 3 with opposite winding directions shows a trend of gradually narrowing width. By setting the width of the support part to gradually decrease from the first end 41 to the second end 42, the shape of the connecting part 4 is adapted to the shape of the depression between the spreading wires, and the depression between the first spreading wire 2 and the second spreading wire 3 can be effectively filled.

[0030] In this embodiment, the thickness of the connecting part 4 is 1 - 10 mm. Preferably, the thickness of the connecting part 4 is the same as the height of the first spreading wire 2 and the second spreading wire 3, so that the outer surface of the connecting part 4 (the outer surface of the connecting part 4 is the surface of the connecting part 4 away from the roller surface) and the outer surface of the spreading wire (the outer surface of the spreading wire is the surface of the spreading wire away from the roller surface) are on the same plane, enabling the soft and light fabric to be laid flat on the middle part of the roller as much as possible, further avoiding the generation of creases. Further, one end of the connecting part 4 away from the roller is the first support surface 5. The roughness of the first spreading wire 2, the second spreading wire 3, and the first support surface 5 is 0.02 - 0.8 μm. The spreading wires and the first support surface are relatively smooth, avoiding abrasion of the fabric.

[0031] As Figures 5-7 shown, the first spreading wire 2 of this embodiment includes a first spreading surface 6 and a second support surface 7 arranged oppositely. One end of the first spreading surface 6 and the second support surface 7 away from the roller surface is provided with a third support surface 8; the second spreading wire 3 includes a second spreading surface and a fourth support surface arranged oppositely. One end of the second spreading surface and the fourth support surface away from the roller surface is provided with a fifth support surface; the second support surface 7 and the fourth support surface are inclined surfaces or arc surfaces, and the second support surface 7 and the fourth support surface are arranged oppositely. The second support surface 7 and the fourth support surface play a role in conducting and supporting the fabric during the spreading process. When the second support surface 7 and the fourth support surface are inclined surfaces, the conduction effect is optimal; when the second support surface 7 is an arc surface, it can be an upward convex arc surface or a downward concave arc surface (as Figure 7 shown). The arc length from the top end to the bottom end of the second support surface 7 is 0 - 40 mm, preferably 10 - 30 mm; the arc length from the top end to the bottom end of the fourth support surface is 0 - 40 mm, preferably 10 - 30 mm.

[0032] The distances from the first support surface 5, the third support surface 8, and the fifth support surface to the roller surface are the same, thus ensuring that the middle part of the fabric is always on the same plane during the unfolding process.

[0033] The height of the first spreading wire 2 and the second spreading wire 3 is 1 - 20 mm, preferably 2 - 10 mm; the width of the third support surface 8 and the fifth support surface is 0 - 40 mm, preferably 2 - 20 mm.

[0034] One end of the first spreading surface 6 and the second supporting surface 7 close to the roller surface is connected through a first mounting surface 9. One end of the second spreading surface and the fourth supporting surface close to the roller surface is connected through a second mounting surface. The widths of the first mounting surface 9 and the second mounting surface are 1-50 mm, preferably 5-30 mm. When the first spreading wire 2 and the second spreading wire 3 are wound around the roller body 1, the first mounting surface 9 and the second mounting surface are used to contact the roller surface.

[0035] A first limiting surface 10 is further provided between the second supporting surface 7 and the first mounting surface 9. A second limiting surface is further provided between the fourth supporting surface and the second mounting surface. The first spreading surface 6 of adjacent first spreading wires 2 contacts the first limiting surface 10, and the second spreading surface of adjacent second spreading wires contacts the second limiting surface. When the limiting surface contacts the spreading surface, the head and tail of the spreading wires can be connected, increasing the friction between the spreading wires and making it not easy to slip.

[0036] The pitches of the first spreading wire 2 and the second spreading wire 3 are 0-200 mm, preferably 0-80 mm. The pitch of the spreading wire in the present invention is small, avoiding wrinkles on the light fabric caused by too large a pitch and affecting the spreading effect. The numbers of the first spreading wire 2 and the second spreading wire 3 are 1-20. By arranging a plurality of first spreading wires 2 and second spreading wires 3 in the present invention, the lead of the spreading roller is increased, and the spreading effect and working efficiency of the spreading roller are improved.

[0037] This embodiment also provides a dyeing and finishing device applying the above new type of spreading roller. The dyeing and finishing device can be a padding mangle, a scouring machine, a drying machine, a singeing machine, a mercerizing machine, a dyeing machine, a printing machine, a finishing machine, etc.

[0038] Embodiment 2

[0039] This embodiment discloses a processing method of a new type of spreading roller, including the following steps: winding the first spreading wire 2 and the second spreading wire 3 from the middle of the roller body 1 to the end of the roller body 1 in sequence. Before winding, fix the first wire head and the second wire head at a preset position on the surface of the roller body 1 (the preset position is the starting point of winding and is set according to actual production needs); cover the connecting piece 4 on the roller surface between the first spreading wire 2 and the second spreading wire 3, and connect the first wire head and the second wire head to the connecting piece 4. The first wire head and the second wire head can be connected to the connecting piece 4 by welding, and the welded solder joints are polished so that the connection between the first wire head, the second wire head and the connecting piece 4 is a smooth plane.

[0040] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the various embodiments of the present invention, and they should all be covered within the scope of the claims and the specification of the present invention.
