Description

Technical Field

[0001] The invention relates to the technical field of dyeing machines, in particular to an upper cloth-carrying dyeing machine without a cloth guide wheel. Background Art

[0002] Airflow dyeing machine is a highly efficient dyeing equipment widely used in the textile industry. It uses high-speed airflow to spray dye evenly onto fabrics to achieve fast and uniform dyeing effects. Compared with traditional dyeing methods, airflow dyeing machine has the advantages of fast dyeing speed, low energy consumption, easy operation and good dyeing effect.

[0003] The working principle of the airflow dyeing machine is to mix the dye and auxiliaries, and then spray the mixture onto the fabric surface through high-pressure airflow, so that the dye quickly penetrates and is evenly distributed in the fiber. This process not only improves the dyeing efficiency, but also reduces the waste of dye. In addition, the airflow dyeing machine is usually equipped with an advanced control system, which can automatically adjust the parameters according to different dyeing requirements to ensure the stability and consistency of the dyeing process.

[0004] In terms of environmental protection, the airflow dyeing machine also shows its advantages. Due to the high utilization rate of dyes in the dyeing process, the discharge of wastewater and waste gas is greatly reduced, which helps to reduce the impact of the textile industry on the environment. At the same time, the airflow dyeing machine has a high degree of automation, which reduces manual operation, reduces labor intensity, and improves production safety.

[0005] In general, airflow dyeing machine has become an indispensable dyeing equipment in the modern textile industry with its high efficiency, energy saving and environmental protection. With the advancement of technology and the growth of market demand, airflow dyeing machine will play a more important role in the field of textile dyeing in the future.

[0006] In the prior art, an airflow dyeing machine, such as an airflow dyeing machine with publication number CN102899826A, has the following technical points: Figure 1 As shown, it includes a cloth lifting wheel chamber 01, a cloth lifting wheel 02, a cloth inlet pipe 03 and a cloth outlet pipe 04. The cloth lifting wheel chamber 01 is provided with the cloth lifting wheel 02, and the cloth inlet pipe 03 and the cloth outlet pipe 04 connected with the cloth lifting wheel chamber 01 are provided outside the cloth lifting wheel chamber 01. The cloth outlet pipe 04 is provided with an independent air nozzle 05 for driving the cloth to move.

[0007] At present, airflow dyeing machines mainly rely on the cloth lifting wheel to drive the cloth, which enters the vaporization chamber through the cloth lifting roller, and drives the cloth to be spray-dyed in the vaporization chamber in cooperation with the air nozzle and the atomized water nozzle. In this process, the spraying direction of the nozzle is opposite to the moving direction of the cloth, thereby ensuring that the dye can be fully sprayed on the cloth and the color is fixed. However, once the rotation speed of the cloth lifting roller is inconsistent with the speed of the nozzle, adverse results such as cloth blockage, cloth entanglement, cloth surface pulling, and cloth width narrowing will occur, which ultimately leads to low cloth quality.

[0008] Therefore, a top cloth-feeding and guide-wheel-free dyeing machine is proposed to solve or alleviate the above problems. Summary of the invention

[0047] Furthermore, the terms “first”, “second”, “third”, etc. are merely used for distinguishing descriptions and are not to be understood as indicating or implying relative importance.

[0048] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] A top cloth-guideless cloth-dyeing machine, such as Figure 2 As shown, it includes a horizontally arranged and cylindrical cloth lifting chamber 501, the bottom of the cloth lifting chamber 501 is connected with an outer tube 407 and a cloth outlet tube 701, there is an angle between the central axis of the outer tube 407 and the cloth outlet tube 701, an air supply component located at the angle between the outer tube 407 and the cloth outlet tube 701 is arranged in the cloth lifting chamber 501, the air supply component supports the concave surface of the cloth passing through the cloth lifting chamber 501, the cloth lifting chamber 501 is connected with a tangential exhaust pipe 601 and a corner exhaust pipe 602 located above it, the exhaust direction of the tangential exhaust pipe 601 is the same as the feeding direction of the outer tube 407, the corner exhaust pipe 602 is arranged at the convex surface of the cloth passing through the cloth lifting chamber 501, and the wind energy in the tangential exhaust pipe 601 is less than the wind energy in the corner exhaust pipe 602;

[0050] like Figure 3 As shown, the outer tube 407 is connected to the dyeing chamber 401, the dyeing chamber 401 is connected to the cloth inlet tube 1, the connection point between the dyeing chamber 401 and the cloth inlet tube 1 is fixedly connected to the overflow tube 404 located in the dyeing chamber 401, the side wall of the dyeing chamber 401 is connected to the liquid inlet tube 403 and the liquid outlet tube 402 located below it, the liquid inlet tube 403 guides the dye into the dyeing chamber 401 to form a dye liquid column, and the dyeing chamber 401 is fixedly connected with a plurality of dye nozzles 405 arranged obliquely upward, the plurality of dye nozzles 405 are divided into two groups, the two groups of dye nozzles 405 are alternately arranged at intervals, and the two groups of dye nozzles 405 alternately spray dye liquid flow in the dye liquid column, and the maximum range of the dye liquid flow sprayed by the dye nozzle 405 is lower than the liquid surface of the dye liquid column.

[0051] When the present invention is actually applied, the cloth can enter the cloth inlet pipe 1 in a circular shape, and then gather into a bundle and pass through the overflow pipe 404. The heated dye is input into the overflow pipe 404 through the liquid inlet pipe 403, and a dye liquid column of a certain height is formed in the overflow pipe 404. The dye falling under the action of gravity can flow back through the liquid outlet pipe 402 to avoid the waste of dye. Since the dye liquid column has a certain flow rate, that is, it has a certain mechanical potential energy, when the cloth passes through the dye liquid column, not only will adsorption occur between the dye and the cloth, but the certain viscosity of the dye itself can also bring resistance to the cloth. This resistance has the effect of overcoming the gravity of the cloth, so that the cloth can be supported by the dye liquid column when it is located in the dye liquid column, thereby further reducing the weight of the cloth that the airflow required in the subsequent steps needs to bear. The two groups of dye nozzles 405 alternately and intermittently spray the dye liquid flow. Since the setting direction of the dye nozzle 405 itself is inclined upward, the dye liquid flow is also sprayed in an inclined upward manner. Not only can the dye be driven into the cloth with greater force, but it can also exert an upward force on the cloth, thereby making it easier for the cloth to move when it needs to, reducing the force required for subsequent structures.

[0052] When the cloth passes through the outer tube 407 and enters the cloth lifting chamber 501, the tangent exhaust pipe 601 and the corner exhaust pipe 602 can generate an upward suction force on the cloth, and the suction force guides the air flow, thereby generating a certain adsorption force on the cloth. Due to the position setting of the tangent exhaust pipe 601 and the corner exhaust pipe 602, the two respectively support the positions on both sides of the cloth reversing point to a certain extent, thereby reducing the force provided by the air supply component on the concave surface of the cloth when it changes direction, preventing the cloth from being too heavy and falling and sticking to the inner bottom surface of the cloth lifting roller, so that the cloth can be suspended, further extending the air drying time of the cloth after being dyed, so that the dye on the cloth can dry and solidify as soon as possible, and then the dye is fixed on the cloth, and finally the cloth can leave through the cloth outlet pipe 701, and during this process, the cloth can still be smoothly transported in the dyeing machine, effectively avoiding the problem of cloth blockage.

[0053] Preferably, if Figure 2 As shown, the air supply assembly includes a plurality of supporting air nozzles 502 penetrating into the cloth lifting chamber 501, and a supporting air pipe 503 connected to the supporting air nozzles 502, the supporting air pipe 503 is connected to a solenoid valve, and the supporting air pipe 503 is connected to an air pump.

[0054] When the air supply component needs to guide the air flow to the concave surface of the cloth when it changes direction for support, the air pump is started to draw air from the outside into the support air pipe 503, and finally pressurized by a number of support air nozzles 502 and sprayed onto the cloth, thereby exerting a certain supporting force on the cloth, allowing the cloth to be suspended in the air, and also accelerating the solidification and drying of the dye on the cloth.

[0055] Preferably, if Figure 4 As shown, the outer circles of the ends of the tangential exhaust pipe 601 and the corner exhaust pipe 602 away from the cloth lifting chamber 501 are fixedly connected with flanges, and the tangential exhaust pipe 601 and the corner exhaust pipe 602 are detachably connected with the final exhaust pipe 603 through connecting flanges, and the connecting flanges are fixedly connected to the end of the final exhaust pipe 603, and the connecting flanges and the flanges are connected by bolts and nuts, and the final exhaust pipe 603 is connected with a suction fan 604.

[0056] When the tangential exhaust pipe 601 and the corner exhaust pipe 602 are providing auxiliary support to the cloth, that is, sucking air to absorb the cloth to reduce the burden of the air supply component outputting the supporting airflow, it is only necessary for the suction fan 604 to work so that the air can leave through the tangential exhaust pipe 601, the corner exhaust pipe 602 and the final exhaust pipe 603 in sequence to generate a suction airflow. In addition, the wind energy provided by the tangential exhaust pipe 601 and the corner exhaust pipe 602 is different, so it is necessary to adjust the output power of the two suction fans 604. The exhaust direction of the tangential exhaust pipe 601 is the same as the feeding direction of the outer tube 407, so it can mainly bear the force at the junction of the cloth reversing and non-reversing, and the corner exhaust pipe 602 is arranged at the convex surface of the cloth passing through the cloth lifting chamber 501, and it also bears the force of the cloth at the reversing point and the non-reversing point, so that the force that the air supply component needs to bear is reduced.

[0057] Preferably, if Figure 4 As shown, a connecting tube 605 embedded in the tangent exhaust pipe 601 and the corner exhaust pipe 602 is detachably connected between the connecting flange and the flange plate, and the connecting tube 605 is open at both ends along the length direction of the end exhaust pipe 603. The end of the connecting tube 605 away from the end exhaust pipe 603 is fixedly connected with a filter screen 606, and the connecting tube 605 is fixedly connected with an adsorption packing layer 1 607, an adsorption packing layer 2 608, and an adsorption packing layer 3 609 which are located above the filter screen 606 and are arranged in sequence. The adsorption packing layer 1 607, the adsorption packing layer 2 608, and the adsorption packing layer 3 609 are activated carbon layers.

[0058] By arranging a connecting tube 605 in the tangent exhaust pipe 601 and the corner exhaust pipe 602, when the two guide the air in the cloth lifting chamber 501 to be sucked and flowed, it can be ensured that the dye droplets, atomized dye, and dye odor sucked from the dyed cloth can be filtered through the adsorption filler layer 1 607, the adsorption filler layer 2 608, and the adsorption filler layer 3 609 before the air is discharged to the outside to avoid affecting the outside air. At the same time, it can also prevent the dye from directly entering the suction fan 604, and prevent the suction fan 604 from getting stuck in the transmission mechanism due to excessive attachment of dye.

[0059] Preferably, if Figure 2 As shown, a clamping tube 408 coaxially arranged therewith is provided inside the outer tube 407, the clamping tube 408 and the lower end of the outer tube 407 are sealed, a return pipe 406 communicating with the outer tube 407 and the clamping tube 408 is fixedly connected to the outer wall of the outer tube 407, and the end of the cloth outlet pipe 701 away from the cloth lifting chamber 501 is connected to the air duct 702, and the air duct 702 is connected to the air outlet 703 located above it, and the air outlet 703 guides the air to flow in the forward or reverse direction.

[0060] The arrangement of the clamping tube 408 ensures that when dye drips from the cloth, the dripping dye can flow back into the dye liquid column as little as possible, thereby preventing the dye that may carry fiber hair or dust after contacting the cloth from contaminating the dye liquid column. These dripping dyes can drip between the clamping tube 408 and the outer tube 407 and leave through the return pipe 406. When the cloth leaves the cloth lifting chamber 501, it can pass through the cloth outlet pipe 701 and the air duct 702, and the air outlet 703 therein can suck air out. In this way, the cloth is supported to a certain extent to prevent it from sticking to the inner wall of the air duct 702, and heated and dry air can also be sent in to further dry the cloth.

[0061] Preferably, if Figure 3 As shown, several dye nozzles 405 are connected to a dye tube, and one end of the dye tube away from the dye nozzle 405 is connected to a dye tank. The dye tubes connected to the two groups of dye nozzles 405 are respectively connected to a primary water pump 808 and a secondary water pump 809, and also include an electric control circuit, which is coupled to the primary water pump 808 and the secondary water pump 809. The electric control circuit controls the primary water pump 808 and the secondary water pump 809 to work alternately and controls the power of both.

[0066] Memory 804, memory 804 is coupled to controller 803, controller 803 receives information transmitted by host computer 802 and extracts control logic from memory 804;

[0067] A / D conversion circuit 805, the input end of the A / D conversion circuit 805 is coupled to the output end of the controller 803, and the A / D conversion circuit 805 performs digital-to-analog conversion on the control signal;

The emitter of the transistor switch 1 is connected in series with a plurality of primary water pumps 808 and then grounded, and the emitter of the transistor switch 2 is connected in series with a plurality of secondary water pumps 809 and then grounded.

[0071] Preferably, if Figure 2 and Figure 5As shown, a gathering cylinder 2 is arranged coaxially with the cloth inlet pipe 1, and both ends of the gathering cylinder 2 pass through the cloth inlet pipe 1 to the extraction air pipe 301 outside, and the extraction air pipe 301 is connected to an exhaust fan.

[0073] The arrangement of the gathering cylinder 2 enables the extraction air pipe 301 to be located in the gap of the cloth when the cloth passes through the cloth inlet pipe 1 in a C-shaped cross section. Then, through the operation of the exhaust fan, the extraction air pipe 301 is utilized to allow the air holes 205 on the gathering cylinder 2 to guide the air in the cloth inlet pipe 1 to flow therein, thereby generating a certain negative pressure, so that the cloth can be adsorbed on the outside of the gathering cylinder 2. Under the action of the convex part 202 and the concave part 204, the cloth can form a petal shape with alternating concave and convex arrangements and leave in a bundle, cooperating with the tangent extraction air pipe 601 to produce the cloth at the non-reversing part, responsible for pulling the upper and lower ends of the cloth at the non-reversing part, thereby reducing The force required by the air supply component is consumed, and the cloth that is gathered and bundled in a petal shape can pass through the opening of the overflow pipe 404 with a smaller cross-sectional area and enter the dye liquid column, and the number of dye nozzles 405 corresponds to the number of recesses 204, so that when the cloth is sprayed with the dye liquid flow in the dye liquid column, the dye liquid flow can also be sprayed at the corresponding position, so that the cloth located in the recesses can collide with each other, so that the force exerted by the dye liquid flow on the cloth can be transmitted to the cloth with a higher transmission ratio, so that the cloth can also be assisted by the spray of the dye liquid flow during the displacement process, thereby reducing the load when other structures drive the cloth.
