Description

Technical Field

[0001] The utility model relates to the technical field of printing and dyeing, in particular to a cloth trough and an O-shaped cylinder dyeing machine suitable for wool dyeing. Background Technique

[0002] The O-shaped dyeing cylinder is a new type of cloth printing and dyeing equipment with the advantage of water saving, which is composed of a cylinder body, a tower head, a cloth trough, etc. The cylinder body is a closed cylindrical structure with a horizontal axis and a cloth inlet on its side. The tower head is located above the cylinder body, and the tower head is provided with a cloth circulating and conveying mechanism and a spray pipe. The cloth trough is in a C-shaped structure and is located inside the cylinder body. The cloth trough has a cloth inlet above and a cloth outlet below. The cloth inlet is connected to the outlet of the spray pipe, and the cloth outlet is connected to the inlet of the cloth circulating and conveying mechanism.

[0003] When wool is dyed, it is inevitable that wool scraps will fall. Because the density of wool is lower than that of the dye liquor, the wool scraps will float on the liquid surface. The height of the dye liquor in the cylinder body only submerges half of the cloth trough. In the past, the upper arc-shaped trough wall of many cloth troughs was complete, so the wool scraps were easily adhered to the small arc surface of the cloth trough. When the water in the cylinder body is drained, it is very difficult to clean the wool scraps. Because it is difficult for the hand to reach the position where wool is easily adhered, and washing with water not only has low efficiency and waste of cost, but also brings a large amount of waste water.

[0004] The structural improvement of the TW088211484U O-type cloth dyeing machine discloses a U-shaped mesh cylinder. In the case of relatively large mesh holes, most of the wool scraps can be discharged from the mesh holes, but the wool scraps are still easy to block the mesh holes, and it is not convenient to clean the wool scraps at this time.

[0005] Therefore, it is necessary to improve the cloth trough structure to solve the above problems. Summary of the Invention

[0006] A main object of the utility model is to provide a cloth trough suitable for wool dyeing, which can reduce the probability of wool scraps adhering to the inner wall of the cloth trough and is convenient for cleaning the wool scraps.

[0007] The utility model realizes the above object through the following technical scheme: A cloth trough suitable for wool dyeing is in a J-shaped pipe structure and is surrounded by a pair of side walls, an upper trough wall, a lower trough wall and a cloth inlet surface. The two side walls are symmetrically structured and form a cloth feeding channel in the middle. An inlet for feeding cloth is arranged on one side of the cloth feeding channel and is opened on the cloth feeding surface, and the other side is the cloth outlet. The upper trough wall is a grid structure.

[0008] Specifically, the two side walls are symmetrically positioned and each has a J-shaped planar structure. The side walls include an inner arc edge, a vertical straight edge, an outer arc edge, and a horizontal straight edge that are connected end to end. The diameter of the inner arc edge is smaller than that of the outer arc edge, and the inner arc edge is located above the outer arc edge. The upper trough wall has an arc-shaped structure centered on a horizontal axis, and both sides of the upper trough wall are connected to the two inner arc edges. The lower trough wall has an arc-shaped water-permeable structure centered on a horizontal axis, and both sides of the lower trough wall are connected to the two outer arc edges. The cloth outlet is located between the two horizontal straight edges, and the cloth inlet surface is connected between the two vertical straight edges.

[0009] Furthermore, the upper trough wall includes an upper outer frame, a plurality of upper connecting rods, and a plurality of upper arc-shaped rods. The upper outer frame is connected to the lower edge of the cloth inlet surface and the inner arc edges of the two side walls. The upper arc-shaped rods are arranged side by side inside the upper outer frame, and the middle parts of all the upper arc-shaped rods are connected by the upper connecting rods.

[0010] Furthermore, the cross-section of the upper arc-shaped rod is circular.

[0011] Furthermore, the lower trough wall includes a lower outer frame, a plurality of lower connecting rods, and a plurality of lower arc-shaped rods. The lower outer frame is connected to the upper edge of the cloth inlet surface and the outer arc edges of the two side walls. The lower arc-shaped rods are arranged side by side inside the lower outer frame, and the outer sides of the middle parts of all the lower arc-shaped rods are connected by the lower connecting rods.

[0012] Furthermore, the cross-section of the lower arc-shaped rod is circular.

[0013] Another main object of the present utility model is to provide an O-type cylinder dyeing machine, which can facilitate the discharge of wool debris during dyeing and avoid the problem of pipeline blockage.

[0014] The present utility model realizes the above object through the following technical solutions: an O-type cylinder dyeing machine further includes a cylinder body and a cloth circulation mechanism. The cloth circulation mechanism is arranged on the upper part of the cylinder body and enables the cloth to enter from the cloth inlet of the cloth trough and be pulled out from the cloth outlet of the cloth trough. An overflow port is provided in the middle of the outer wall of the cylinder body.

[0015] Specifically, two sets of cloth circulation mechanisms and cloth troughs are provided on the cylinder body, and each cloth circulation mechanism in each group corresponds to a cloth trough.

[0016] Specifically, a drain port and a manhole are provided at each position near the lowest point on the side walls at both ends of the cylinder body.

[0017] The beneficial effects of the technical solution of the present utility model are:

[0018] 1. When the woolen fabric moves in the fabric feeding channel, wool scraps will float up. However, most of the wool scraps will pass through the upper trough wall of the grille structure and float away with the water flow. Even if a small part of the wool scraps adheres to the grille, as long as the gap of the grille is large enough for a finger to enter, it can be easily wiped off, greatly simplifying the cleaning operation and reducing the generation of cleaning wastewater.

[0019] 2. The overflow port is located at the position flush with the liquid level in the cylinder body. Since the wool scraps will float on the liquid surface, the overflow port can timely let the wool scraps leave the cylinder body with the overflowing dye liquor, reducing the risk of the wool scraps adhering back to the fabric after drainage.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The present utility model will be further described in detail below with reference to specific embodiments.

[0029] Embodiment:

[0030] As Figure 1 shown, an O-shaped cylinder dyeing machine suitable for wool dyeing according to the present utility model includes a cylinder body 1, a fabric circulation mechanism 2 and a fabric trough 3. The fabric circulation mechanism 2 is arranged above the cylinder body 1 and enables the fabric to enter from the fabric inlet 341 of the fabric trough 3 and be pulled out from the fabric outlet of the fabric trough 3.

[0031] The cylinder block 1 is used to hold the dyeing solution, and the cloth trough 3 is used to accommodate the fabric to be dyed. The fabric circulation mechanism 2 is equipped with a spraying mechanism, which is used to spray the dyeing solution on the fabric during the movement of the fabric. When dyeing, the fabric is twisted into a strand and connected end to end, and continuously passes through the cloth trough 3 under the drive of the fabric circulation mechanism 2. The dyeing solution will also continuously circulate in the spraying mechanism and the cylinder block 1. The part of the fabric in the cloth trough 3 is loose and extends in a serpentine shape, and the liquid level in the cylinder block 1 submerges the loose part of the fabric 3.

[0032] As Figure 1 and Figure 2 shown, two sets of fabric circulation mechanisms 2 and cloth troughs 3 are provided on the cylinder block 1, and the fabric circulation mechanism 2 in each set corresponds to a cloth trough 3.

[0033] There are two relatively independent printing and dyeing spaces in the cylinder block 1, so that two pieces of fabric can be printed and dyed simultaneously. Different fabrics are placed in different cloth troughs 3 and are respectively operated by a fabric circulation mechanism 2. This can double the processing efficiency of the O-shaped cylinder dyeing machine.

[0034] As Figure 3 and Figure 4 shown, the cloth trough 3 has a J-shaped tube structure and is surrounded by a pair of side walls 31, an upper trough wall 32, a lower trough wall 33 and a fabric feeding surface 34. The two side walls 31 are symmetrically structured and form a fabric feeding channel in the middle. One side of the fabric feeding channel is provided with a fabric inlet 341 opened on the fabric feeding surface 34, and the other side is the fabric outlet. The upper trough wall 32 is a grille structure, and the grille structure has gaps for fingers to enter.

[0035] When the fabric made of wool moves in the fabric feeding channel, wool scraps will float up, but most of the wool scraps will pass through the upper trough wall 32 of the grille structure and float away with the water flow. Even if a small part of the wool scraps adheres to the grille, as long as the gap of the grille is large enough for fingers to enter, it can be easily wiped off, greatly simplifying the cleaning operation and reducing the generation of cleaning wastewater.

[0036] The two side walls 31 are symmetrically located and each has a J-shaped planar structure. The side wall 31 includes an inner arc edge 311, a vertical straight edge 312, an outer arc edge 313 and a horizontal straight edge 314 connected end to end. The diameter of the inner arc edge 311 is smaller than that of the outer arc edge 312. The inner arc edge 311 is located above the outer arc edge 313. The upper trough wall 32 has an arc-shaped structure centered on the horizontal axis, and both sides of the upper trough wall 32 are connected to the two inner arc edges 311. The lower trough wall 33 has an arc-shaped water-permeable structure centered on the horizontal axis, and both sides of the lower trough wall 32 are connected to the two outer arc edges 313. The fabric outlet is located between the two horizontal straight edges 312, and the fabric feeding surface 34 is connected between the two vertical straight edges 314.

[0037] The cloth trough 3 is a splicing structure, where the lower trough wall 33 itself needs to be permeable to water, thus facilitating the flow of the dye liquor. The lower trough wall 33 has to support the cloth accumulated in the cloth feeding channel without impeding the movement of the cloth.

[0038] As Figure 3 and Figure 4 shown, the upper trough wall 32 includes an upper outer frame 321, several upper connecting rods 322 and multiple upper arc-shaped rods 323. The upper outer frame 321 is connected to the lower edge of the cloth feeding surface 34 and the inner arc edges 311 of the two side walls 31. The upper arc-shaped rods 323 are arranged side by side inside the upper outer frame 321. The middle parts of all the upper arc-shaped rods 323 are connected by the upper connecting rods 322. The cross-section of the upper arc-shaped rods 323 is circular.

[0039] The upper connecting rods 322 are used to keep the spacing of the upper arc-shaped rods 323 stable. Since the upper trough wall 32 generally does not come into direct contact with the cloth, the upper connecting rods 323 can be connected either to the upper part or the lower part of the upper arc-shaped rods 323. The upper arc-shaped rods 323 need to allow wool debris and the dye liquor to pass through the gaps, reducing the risk of wool debris sticking, so the surface should preferably adopt a smooth structure.

[0040] As Figure 3 and Figure 4 shown, the lower trough wall 33 includes a lower outer frame 331, several lower connecting rods 332 and multiple lower arc-shaped rods 333. The lower outer frame 331 is connected to the upper edge of the cloth feeding surface 34 and the outer arc edges 313 of the two side walls 31. The lower arc-shaped rods 333 are arranged side by side inside the lower outer frame 331. The outer sides of the middle parts of all the lower arc-shaped rods 331 are connected by the lower connecting rods 332. The cross-section of the lower arc-shaped rods 331 is circular.

[0041] This kind of lower trough wall 33 also adopts a grid structure. The extending direction of the lower arc-shaped rods 331 is along the overall moving direction of the cloth, so it will not affect the movement of the cloth. The lower connecting rods 332 are used to keep the spacing of the lower arc-shaped rods 333 stable. Since the inner side of the lower arc-shaped rods 333 has to contact the cloth, in order not to affect the movement of the cloth, the lower connecting rods 332 can only be arranged on the outer side of the lower arc-shaped rods 333. The circular cross-section of the lower arc-shaped rods 331 represents a smooth surface, so it will not scratch the cloth.

[0042] As Figure 1 and Figure 2 shown, at the position near the lowest point on both end side walls of the cylinder body 1, there is a drain port 11 and a manhole 12 respectively.

[0043] The drain port 11 is used to discharge the used dye liquor. If the dye liquor contains wool debris or other solid impurities, the bottom of the cylinder body 1 can be cleaned through the manhole 12 to prevent contamination of the next dye liquor.

[0044] As Figure 1and Figure 2 As shown in Figure 2 , an overflow port 13 is provided in the middle of the outer wall of the cylinder block 1.

[0045] The overflow port 13 is at the position flush with the liquid level in the cylinder block 1. Since the wool scraps will float on the liquid surface, the overflow port 13 can timely let the wool scraps leave the cylinder block 1 along with the overflowing dye liquor, reducing the risk of the wool scraps adhering back to the fabric after drainage.

[0046] The above are only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the inventive concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
