Description

Cloth dyeing machine

Technical Field

The invention belongs to the technical field of dyeing, relates to a dyeing device, and particularly relates to a cloth dyeing machine for dyeing cloth.

Background

Referring to fig. 8, 9 and 10, a cloth dyeing machine is a machine for dyeing cloth by immersing the cloth in a continuously flowing dyeing solution; the prior art dyeing machine structurally comprises an upper dye vat 91, a lower dye vat 92, a cloth guide tube 93 and a heat exchanger 94, wherein two ends of the cloth guide tube 93 are respectively connected with the upper dye vat 91 and the lower dye vat 92, the heat exchanger 94 is respectively connected with the cloth guide tube 93 and the lower dye vat 92, and the lower dye vat 92 contains dye liquor 95 for dyeing.

When the dyeing machine is used, the dye liquor 95 is put into the upper dye vat 91, the cloth 96 to be dyed is put into the lower dye vat 92 from the end of the cloth guide tube 93 adjacent to the lower dye vat 92, the cloth 96 extends into the lower dye vat 92 from one path in the cloth guide tube 93, winds back into the upper dye vat 91 and then is communicated with the cloth guide tube 93 again to form a circulation, and the dye liquor 95 is pushed by a pump 97 before dyeing to enter a heat exchanger 94 for heating and warming, then enters the circulation of the cloth guide tube 93 and the cloth 96, and is continuously contacted with the cloth 96 in the circulation through the dye liquor 95, so that the aim of dyeing the cloth 96 is fulfilled.

Referring to fig. 11, more precisely, in the dyeing machine of the prior art, a bottom plate 921 is provided in the lower dye vat 92, a plurality of dye solution holes 922 are provided on the bottom plate 921, the dye solution holes 922 allow the dye solution 95 to flow downward from the dye solution holes 922 after entering the lower dye vat 92, and further flow to a pump 97 provided below the lower dye vat 92, and the energy of the pump 97 is used to re-drive the dye solution 95 into the cloth guide tube 93 above the lower dye vat 92, so that the dye solution 95 can continuously flow in the circulation; on the other hand, the bottom plate 921 is also used to prevent the cloth 96 from entering the circulation used by the dye solution 95, and further prevent the cloth 96 from entering the components for treating the dye solution 95, such as the heat exchanger 94, and to prevent the components from being damaged.

In addition, since the dye solution 95 is heated before use and cooled during recycling or replacement, the dye solution 95 must be heated by the heat exchanger 94 before entering the circulation, and the heat exchanger 94 is configured to have a parallel heating device and cooling device (not shown) mounted outside a straight pipeline, wherein after the dye solution 95 enters the pipeline, one of the devices is turned on according to the requirement to exchange energy with the dye solution 95 in the pipeline, and after the dye solution 95 is properly heated or cooled, the next dyeing or recycling operation can be performed.

However, the prior art dyeing machine has the following several disadvantages.

First, because more or less lint may fall off the piece of cloth 96, the lower vat 92 may float a lot of lint at the same time when the piece of cloth 96 is dyed in the lower vat 92; generally, the cotton fibers should be discharged from the dye liquor hole 922, but because the cloth 96 with a weight heavier than that of the cotton fibers is easy to sink in the lower dye vat 92, and the water flow of the dye liquor 95 flowing downwards also tends to sink the cloth 96 to block the dye liquor hole 922, the cotton fibers cannot be effectively retained in the lower dye vat 92 through the dye liquor hole 922, and then the cotton fibers are stuck on the cloth 96, so that the dyed cloth 96 is difficult to clean.

Secondly, cotton wool which is not discharged out of the lower dye vat 92 for a long time gradually accumulates on the bottom plate 921, so that a lot of cotton wool is easily deposited around the dye liquor holes 922, the cotton wool easily blocks the dye liquor holes 922, the dye liquor 95 cannot effectively move to the pump 97 below the lower dye vat 92 through the dye liquor holes 922, and the pump 97 is idle and is worn;

thirdly, in order to avoid the second disadvantage, the dyeing machine of the prior art is usually filled with much more dyeing liquid 95 than the required amount, and the excess dyeing liquid 95 is used to maintain a certain amount of liquid in the pump 97, but this increases the usage amount of the dyeing liquid 95; in other words, in the dyeing machines of the prior art, the ratio of the dyeing liquid 95 to the whole internal space is high (high liquid ratio), causing the prior art to be inefficient in terms of the cost of the dyeing liquid 95;

fourth, in the heat exchanger 94 of the prior art, since the heating device and the cooling device are arranged in parallel and exchange energy for the same pipeline, some energy is cancelled each other in use; for example, after the heating device exchanges heat with the dye liquor 95, when the dye liquor 95 is dyed and is to be cooled and recycled, if the temperature in the pipeline is still too high or even the heating device itself is not completely cooled, when the cooling device is turned on, a part of energy is absorbed by the heating device or the pipeline and cannot be completely used for cooling the dye liquor 95, and vice versa.

Fifth, another disadvantage of the prior art heat exchanger 94 in which the heating device is disposed outside the pipeline is that the heating device does not heat only the pipeline on the inner side thereof when it is activated because the heat source is not directional when it is diffused by the heating device, and a portion of the heat source is diffused and dissipated, resulting in unnecessary energy consumption.

Sixth, in the heat exchanger 94 of the prior art, when the cooling device is in operation, the flow speed of the coolant inside the cooling device is too high, so that the temperature of the dye solution 95 is too high when the dye solution is cooled by the cooling device, and the cloth 96 is easily wrinkled and deformed when contacting with the dye solution.

Seventh, the heat exchanger 94 of the prior art has disadvantages in operation, and the heating device and the cooling device are horizontally arranged in parallel, so that the horizontal volume of the whole heat exchanger 94 is too large, and thus the heat exchanger occupies a large amount of space, and the space utilization is inefficient.

Disclosure of Invention

In view of the disadvantages and drawbacks of the prior art, the present invention provides a cloth dyeing machine, which achieves low liquid ratio and energy saving by changing the position of the dyeing liquid holes on the partition plate and reconfiguring the structure of the heat exchanger.

The invention has the advantages that through the structure for isolating the dye liquor and the cloth in the lower dye vat, the bottom plate in the prior art is changed into the partition plate used by the invention, wherein the partition plate comprises the bottom plate and the two side plates, so that the dye liquor hole for circulating the dye liquor can be changed and arranged on the two side plates, and because the included angle of the side plates compared with the bottom plate is 90 degrees, even if the cloth is sunk at the bottom of the lower dye vat due to heavier weight in the dyeing process, lighter cotton wool can flow out from the side plates at the two sides and can not be blocked by the cloth, so that the accumulated cotton wool is not easy to remain on the side plates; in other words, the flow of the dyeing liquid is not obstructed by the cloth, and the dyeing liquid hole is not gradually reduced because the dyeing liquid hole is blocked after long-term use, so that a user does not need to add more dyeing liquid into the whole dyeing cycle to avoid idle rotation caused by insufficient liquid in the pump, and the advantages of low liquid consumption (low liquid ratio) and material saving can be achieved, and the efficiency of the pump during operation can be effectively maintained.

In an embodiment of the present invention, the heat exchange assembly further includes a heater connected to the fabric guide tube and communicating with the inside thereof; the cooler is arranged at intervals with the heater, the height position of the cooler is lower than that of the heater, and the cooler is connected and communicated with the heater through at least one pipe body; and the two opposite ends of the dye liquor filter are respectively connected with the cooler and the lower dye vat of the dyeing component, and the interior of the dye liquor filter is respectively communicated with the cooler and the lower dye vat.

The heater and the cooler of the heat exchange assembly are arranged at intervals up and down, so that the heater and the cooler are separated by an effective distance, in other words, when the operation between the heater and the cooler cannot be influenced mutually, the heat exchanger can more effectively convert consumed energy to heating or cooling dye liquor, and therefore, compared with the heat exchanger in the prior art, the heat exchanger is more energy-saving.

More precisely, since one of the connection plates 26 is further disposed between each side plate 25 and the bottom plate 24 in the present embodiment, the included angle between the bottom plate 24 and each side plate 25 is the included angle between the extension plane of the top surface 241 of the bottom plate 24 and the extension plane of the side plate 25 adjacent to the side surface 251 of the bottom plate 24 in the present embodiment.

Each side plate 25 is further formed with a plurality of dyeing holes 252, and in this embodiment, the inner tank 22 and the outer tank 23 communicate with each other through the dyeing holes 252.

Referring to fig. 7, in another embodiment of the present invention, a plurality of dyeing liquid holes 252A may also be formed on the connecting plate 26A, and the further dyeing liquid holes 252A may improve the fluidity of the present invention during use.

Referring to fig. 1 and 2, opposite ends of a cloth guide 30 are respectively connected to an upper vat 10 and a lower vat 20, and the inside of the cloth guide 30 is communicated with the upper vat 10 and the lower vat 20.

Referring to fig. 4 and 5, the circulation assembly includes a heat exchange assembly 40 and a pump 50, opposite ends of the heat exchange assembly 40 are connected to and communicated with the cloth guide 30 and the pump 50, respectively, and the pump 50 is further connected to and communicated with the lower dye vat 20.

Referring to fig. 2 and 4, more precisely, the heat exchange assembly 40 includes a heater 41, a cooler 42 and a dye liquor filter 43 sequentially connected to each other, the heater 41 is connected to the cloth guide 30 and the interior of the heater 41 is also connected to the cloth guide 30, the cooler 42 and the heater 41 are spaced apart from each other, the height of the cooler 42 is lower than that of the heater 41, and the heater 41 and the cooler 42 are connected to each other through at least one tube 44, in this embodiment, the number of the at least one tube 44 is two, and the at least one tube is an upper tube 441 and a lower tube 442, but the number of the at least one tube 44 is not limited thereto, the opposite ends of the dye liquor filter 43 are respectively connected to the cooler 42 and the lower dye vat 20 of the dyeing assembly, and the interior of the dye liquor filter 43 is respectively connected to the cooler 42 and the lower dye vat 20.

Referring to fig. 6, in the present embodiment, the heater 41 further includes a housing 411, a mounting frame 412 and a heating rod 413, the mounting frame 412 is disposed in the housing 411, the heating rod 413 is disposed on the mounting frame 412, is located in the housing 411, and is spaced from an inner wall surface of the housing 411; the internal structure of the heater 41 is not limited to the above.

The cooler 42 is disposed below the heater 41, more precisely, when viewed from the side, the cooler 42 is disposed obliquely below the heater 41, and the cooler 42 includes a cooling tank 421, a plurality of spoilers 422 and a plurality of dyeing pipes 423, the spoilers 422 are disposed in the cooling tank 421 at intervals, the outer periphery of each spoiler 422 includes an attaching periphery 424 and a gap periphery 425, and two ends of the gap periphery 425 are respectively connected to two ends of the attaching periphery 424; in other words, for each spoiler 422, the conforming rim 424 and the clearance rim 425 form a complete rim around it.

The contact peripheral edge 424 contacts the inner wall surface of the cooling tank 421, a flow gap 426 is formed between the gap peripheral edge 425 and the inner wall surface of the cooling tank 421, and the gap between the spoilers 422 and the channel formed by the flow gap 426 form a curved flow space in the cooling tank 421.

More precisely, the flow gaps 426 divide the interior of the cooling slot 421 into a curved flow space because the flow gaps 426 of two adjacent spoilers 422 are arranged in a staggered manner, i.e., if the flow gap 426 of one spoiler 422 is formed on the top surface of the inner wall surface of the cooling slot 421 in a side view, the flow gap 426 of the other spoiler 422 adjacent to the spoiler 422 is formed on the bottom surface of the inner wall surface of the cooling slot 421, but the arrangement of the flow gaps 426 is not limited to the above, and only the two adjacent flow gaps 426 are not completely overlapped in a side view, i.e., in other embodiments, the two adjacent flow gaps 426 may also be arranged in a partially staggered manner.

The dyeing liquid pipes 423 are accommodated in the cooling tank 421 through the spoiler 422, and opposite ends of each dyeing liquid pipe 423 are connected to the heater 41 and the dyeing liquid filter 43, respectively, more precisely, when the dyeing liquid 95 passes through the cooling tank 421 through the dyeing liquid pipe 423, the dyeing liquid 95 does not substantially enter the cooling tank 421, but passes through the cooling tank 421 through the dyeing liquid filter 43 at intervals of the dyeing liquid pipe 423 and directly enters the heater 41.

The following are aspects of the invention and advantages thereof.

Referring to fig. 4, when the present invention is used, the cloth 96 is placed into the upper dye vat 10 for dyeing circulation, wherein a cloth carrying wheel 11 is further disposed inside the upper dye vat 10, after a user winds the cloth 96 around the cloth carrying wheel 11, the cloth 96 can be driven inside the present invention through the rotation of the cloth carrying wheel 11, and the cloth carrying wheel 11 is prior art, and therefore, further description is omitted.

The cloth 96 put into the present invention is driven by the cloth-carrying wheel 11 to pass through the cloth-guiding tube 30 and the lower dye vat 20 in sequence from the upper dye vat 10, and finally to be wound back into the upper dye vat 10, and this cycle is hereinafter referred to as a cloth cycle.

Referring to FIGS. 3, 4 and 5, on the other hand, the dye liquor 95 enters the present invention from the upper vat 10, but the path along which the dye liquor 95 travels (hereinafter referred to as the dye liquor circulation) is different from that of the cloth 96. more precisely, after entering the upper vat 10, the dye liquor 95 also travels along the cloth guide tube 30 to the lower vat 20, flows through the dye liquor hole 252 of the side plate 25 of the partition plate 21 from the inner tank 22 to the outer tank 23 in the lower vat 20, and enters the pump 50 through the connection with the pump 50 below the outer tank 23. more precisely, the partition plate 21 can be used to isolate the cloth 96 from the pump 50, thereby preventing the cloth 96 from accidentally entering the pump 50 and causing the malfunction of the pump 50.

After entering the pump 50, the dye liquor 95 is pushed by the pump 50 to sequentially pass through the dye liquor filter 43, the cooler 42 and the heater 41, and is pushed all the way up to the joint of the cloth guide tube 30 and the upper dye vat 10, more precisely, in the process of passing through the heat exchange assembly 40, the user can turn on the heater 41 or the cooler 42 according to the requirement, so that the dye liquor 95 can be properly temperature-adjusted when passing through.

After entering the joint of the cloth guide tube 30 and the upper dye vat 10, the dye solution 95 can be sprayed into the cloth guide tube 30 through a nozzle seat 31 disposed at the joint, and then flows into the lower dye vat 20 through the cloth guide tube 30 again, so as to complete the dye solution circulation.

After the dye liquor 95 and the cloth 96 after the heat exchange are fully mixed in the invention, the cloth 96 can be dyed with the color that the user wants to add by mixing in the lower dye vat 20, thereby achieving the purpose of dyeing.

Among other things, the present invention provides the following advantages.

Firstly, referring to fig. 3, in the lower dye vat 20, the dyeing liquid hole 252 is disposed on the side plate 25, and since a certain included angle (90 degrees) is formed between the side surface 251 of the side plate 25 and the top surface 241 of the bottom plate 24, cotton wool dropped from the cloth 96 during the dyeing process can be smoothly discharged from the dyeing liquid hole 252, because the cloth 96 sinks on the bottom plate 24, and does not block the dyeing liquid hole 252 disposed on the side plate 25; furthermore, when the cotton wool does not accumulate in the lower vat 20, the dyeing liquid holes 252 are not blocked by the cotton wool, thus maintaining the fluidity of the dyeing liquid 95 inside the present invention.

Secondly, as mentioned in the first point, since the cotton wool will not block the dyeing liquid hole 252, the user will not need to worry about the problem that the dyeing liquid hole 252 will not be blocked and a certain amount of the dyeing liquid 95 will not flow downward into the pump 50, thereby causing the pump 50 to idle, in other words, the present invention can effectively reduce the amount of the dyeing liquid 95 added during the actual operation, thereby achieving the advantages of low liquid ratio and raw material cost saving.

Thirdly, referring to fig. 2, 5 and 6, in the structural design of the heat exchange assembly 40, the heater 41 and the cooler 42 are arranged at intervals up and down, and the two pipes 44 are only used for communicating the interiors of the two pipes, so that the influence of the temperature of one device on the other device can be effectively reduced when the other device is in operation; for example, when the cooler 42 is in operation, since the cooler 42 is spaced from the heater 41, the residual temperature remained on the heater 41 is less likely to be transferred to the cooler 42 even though the temperature of the heater 41 is not reduced to room temperature after the operation of the heater 41 is stopped, so that the cooler 42 can effectively transfer the cooling efficiency thereof to the dye solution 95 passing through the cooler more completely, thereby achieving the effect of saving the operation energy.

Fourthly, in the design of the heater 41, the heating rod 413 is disposed inside, in other words, when the heating rod 413 generates heat, the energy transmission in all directions is toward the inside of the shell 411, so that when the inside of the shell 411 is filled with the dye solution 95 and heated, the energy of the heating rod 413 can be completely transmitted to the dye solution 95 without being lost through the shell 411.

Fifth, the heating rod 413 of the present invention is adhered with many impurities carried by the dyeing liquid 95 after long-term use, but the heating rod 413 is configured like an electric spoon of a common hot water kettle, so that it is very convenient to assemble and disassemble, and a user can rapidly disassemble and clean the heating rod and then replace the heating rod, thereby achieving the purpose of conveniently maintaining the heater 41.

Sixth, the flow gap 426 is disposed inside the cooler 42 of the heat exchange assembly 40, so that the flow rate of the cooling liquid (not shown) flowing inside the cooler 42 can be effectively reduced, that is, when the cooling liquid runs in the cooling tank 421 and cools the dye solution 95 passing through the cooling tank 421 from the dye tube 423, the flow rate is not too fast, and thus the process of reducing the temperature of the dye solution 95 can be slowed down, and the negative effect on the cloth 96 caused by the too fast temperature reduction of the dye solution 95, such as the wrinkle and easy deformation of the cloth 96, can be avoided.

Seventh, the heater 41 and the cooler 42 are arranged at a distance from each other, which not only helps to save energy, but also frees up much space adjacent to the present invention, so that the user can use the space to place the chemical adding tank 81, the preparation tank 82, or the electrical control box 83, etc. shown in fig. 1, which are related to the operation of the present invention, thereby saving the space usage of the field.

Although the present invention has been described with reference to the preferred embodiments, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
