Description

Technical Field

[0001] The invention relates to the technical field of printing and dyeing, and in particular to a cloth dyeing machine with a double-circulation operation structure. Background Art

[0002] For this reason, the current dyeing machines are roughly divided into two types, one is the type without a cloth guide wheel, and the other is the type with a cloth guide wheel;

[0003] The machine with a cloth guide wheel, that is, a cloth guide wheel is provided in the head of the dyeing machine, and a nozzle is provided on the lower side of the cloth guide wheel; when the dyeing cycle is running, the cloth guide wheel quickly pulls up the cloth in the cloth storage tank, and then the spray-pressed dye liquid sprayed from the nozzle drives the cloth to circulate and dye. Since the cloth is first driven by the auxiliary cloth guide wheel, it is suitable for dyeing thick and heavy cloth, including blended cloth such as cotton and linen, and cloth that is not easy to be scratched; and the machine with a cloth guide wheel can use a smaller spray-pressed dye liquid to drive the cloth to circulate, so it is also suitable for dyeing cloth that is easy to crack and shift, but the cloth sometimes produces excessive sliding friction with the cloth guide wheel roller on the cloth guide wheel, resulting in scratches and aurora prints.

[0004] The non-guide wheel type, that is, the dyeing machine head does not have a guide wheel, but a nozzle is provided in the head to spray dye liquid in the direction of the head door cover, and the cloth is driven by the spray dye liquid sprayed by the nozzle to circulate and dye. This non-guide wheel type is suitable for dyeing high-weave, high-density, high-spandex, four-way stretch, thin and light fabrics that are easy to be scratched because the cloth does not contact and rub with the cloth lifting roller during the circulation process. However, since it is purely driven by the dye liquid, the driving force on the cloth is limited, and it is not suitable for heavy cloth.

[0005] The two types of machines have their own advantages and disadvantages, and each has its own applicable and inapplicable fabrics. Therefore, in order to dye a variety of fabrics with different materials and different process requirements, general dyeing factories can only purchase both models with and without guide wheels. However, since the types and quantities of fabrics suitable for dyeing with guide wheels and without guide wheels on the market will be affected by factors such as seasons or changes in market demand, there will be too many machines without guide wheels or too many machines with guide wheels left idle, resulting in idle waste and affecting production costs. Summary of the invention

[0006] In order to solve at least one of the technical problems mentioned in the background technology, the object of the present invention is to provide a cloth dyeing machine with a double-circulation operation structure, so as to be applicable to dyeing a wider variety of cloth types in one machine model.

[0022] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figures 1 to 3 The present embodiment provides a cloth dyeing machine with a double-circulation operation structure, including a machine body 12, a machine head 11, and a cloth guide tube 15 arranged at the lower side of the machine body 12, one end of the cloth guide tube 15 is connected to the machine head 11, and the other end is connected to the rear end of the machine body 12, and the machine head 11, the cloth guide tube 15, and the machine body 12 together form a path for the cloth to circulate.

[0024] Reference Figure 2 As shown, a cloth storage tank is provided in the machine body 12, and a machine head 11 is provided with a machine door 14 and a machine door 14 cover for covering and sealing the machine door 14. The cloth enters the cloth storage tank at the machine door 14 and is stacked. During the dyeing operation, the cloth is introduced into the cloth guide tube 15 from the opening of the machine head 11, and then led out from the cloth guide tube 15 at the opening at the rear end of the machine body 12 and returned to the machine body 12, forming a circular moving track.

[0025] Regarding the driving of the cloth in the dyeing machine, this embodiment drives the cloth to circulate and dye by spraying dye liquid onto the cloth. Figure 3 A cloth guide wheel 21 is arranged in the head 11, and the cloth guide wheel 21 is mainly composed of a main body and a plurality of cloth guide wheel 21 rollers distributed in a circular array on the main body. There are a lot of descriptions and applications of this kind of cloth guide wheel 21 in the prior art, so no excessive description is made here; when working, the cloth guide wheel 21 lifts the cloth stacked in the cloth storage tank upward, and the dye liquid pushes the cloth into the cloth storage tank through the cloth guide pipe 15 for stacking and circulation.

[0026] The dye liquid spraying function is mainly realized by the first nozzle 31, which is arranged at the front end of the cloth storage tank and sprays toward the cloth guide wheel 21. Figure 3 As shown, the rotation direction of the cloth guide wheel 21 is counterclockwise in the figure, that is, the first nozzle 31 sprays the cloth on the upper part of the cloth guide wheel 21 to achieve a pushing effect.

[0027] In addition, a second nozzle 32 is used to assist the pulling effect. The second nozzle 32 is arranged in the fabric guide tube 15 , close to the machine head 11 . The second nozzle 32 sprays dye liquid downward into the fabric guide tube 15 to pull the fabric toward the rear end of the machine body 12 .

[0028] The method of lifting the cloth by the cloth guide wheel 21 and driving the cloth to circulate by the auxiliary jet of dye liquid is suitable for thick and heavy cloths, blended cloths containing cotton, linen, etc., and cloths that are not easy to be scratched. Because of the assistance of the cloth guide wheel 21, the required dye liquid spraying pressure can be relatively small, so it is also suitable for dyeing cloths that are easy to crack and shift. However, since the cloth and the cloth guide wheel 21 are in contact at all times and the contact area is mostly small, excessive sliding friction will occur, resulting in problems such as cloth scratches and aurora prints.

[0029] Therefore, in order to solve the problem of fabric abrasion and aurora print while retaining the effect of the cloth guide wheel 21, this embodiment further provides an arc-shaped guide tube 22 in the machine head 11, and the arc-shaped guide tube 22 is fixedly installed in the machine head 11 through a clamp to achieve a detachable installation. The arc-shaped guide tube 22 includes two openings, one of which is connected to the opening of the cloth guide tube 15 in the machine head 11, and the other opening faces the first nozzle 31 in the cloth storage tank. A nozzle 31 sprays dye liquid into the arc-shaped guide tube 22 through the opening. When dyeing cloth, due to the installation of the arc-shaped guide tube 22, the cloth does not contact the cloth guide wheel 21, and is not pulled by the cloth guide wheel 21, but passes through the arc-shaped guide tube 22 and is introduced into the cloth guide tube 15, forming a circulation operation. The dye liquid is sprayed and poured into the arc-shaped guide tube 22 through the first nozzle 31, and the dye liquid flows in the arc-shaped guide tube 22 to push the cloth to move and dye.

[0030] Compared with the pulling of the cloth guide wheel 21 which is mostly point and line contact, the inner wall of the arc-shaped guide tube 22 has a larger contact area with the cloth, and the sliding friction generated is smaller. Moreover, since the arc-shaped guide tube 22 does not directly act on the cloth like the cloth guide wheel 21, but is filled with flowing dye liquid through its internal space, and the cloth is driven by the flow of the dye liquid, with the dye liquid as the moving medium, the sliding friction generated by the cloth is avoided to a great extent, and the problems of abrasion and aurora printing are avoided. Therefore, it is suitable for dyeing high-weave, high-density, high-spandex, four-way stretch, thin and other easily abraded cloths.

[0031] In addition, the arc-shaped guide tube 22 is detachably connected and arranged in the machine head 11, and is fixed by bolts or the like. The dyeing method can be selected according to the type of fabric. It is only necessary to disassemble and assemble the arc-shaped guide tube 22. When removed, the fabric is circulated and dyed through the fabric guide wheel 21. When installed, the fabric is circulated and dyed through the arc-shaped guide tube 22.

[0032] During the dyeing work performed by the cloth guide wheel 21, the dye liquid sprayed from the first nozzle 31 directly hits the cloth guide wheel 21. Since the dyeing work requires opening the machine door 14 cover from time to time to observe the dyeing condition of the cloth, when the machine door 14 cover is opened, the dye liquid will rush out of the machine door 14, causing trouble. Therefore, in this embodiment, a water baffle 4 is provided at the inner edge of the machine door 14 to block the sprayed dye liquid and make it flow downward, thereby preventing the dye liquid from rushing out of the machine door 14.

[0033] A recoil spray ring 5 is also provided at the front end of the cloth storage tank. When the cloth circulates, it passes through the recoil spray ring 5. The recoil spray ring 5 sprays dye in the opposite direction of the cloth running direction, so that when the cloth is stuck and stacked on the cloth guide wheel 21 or the arc-shaped guide tube 22, a small section of cloth can be withdrawn by recoil dye.

[0034] The first nozzle 31, the second nozzle 32 and the backwash spray ring 5 are respectively used to control the dye liquid spraying amount through independent flow control valves.

[0035] It should be added that most of the existing dyeing machines have a single cylinder and a single cloth storage tank, which dyes a strip of cloth inside. In order to improve efficiency, the cylinders of two dyeing machines are usually installed side by side and connected by pipes. The two dyeing machines dye cloth at the same time, each dyeing a strip of cloth, and the dye liquid in the two cylinders is connected and shared through pipes, which saves dye liquid and improves dyeing efficiency.

[0036] However, in this way, it is difficult to ensure that the cycle time and number of cycles of the cloth in the two drums are consistent throughout the dyeing process, which leads to the problem of inconsistent dyeing degree of the cloth in the two drums. Therefore, in another embodiment, two drum bodies are provided, the two drum bodies are placed side by side, the two drum bodies are connected, and the internal cloth storage tanks are directly connected, so that the dye liquid in the two drum bodies can be directly connected, thereby ensuring that the dye liquid in the dyeing process is more uniform and the dyeing uniformity is better.

[0037] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
