Description

Technical Field

[0001] This utility model relates to the technical field of textile fabric processing equipment, and in particular to a rapid dehydration device for tie-dyeing textile fabrics. Background Technology

[0002] Tie-dyeing is a traditional and unique dyeing technique in China. Its main processes include binding the fabric, dyeing, washing, and dehydrating / drying. In modern textile production, to improve efficiency, specialized dehydration equipment is typically used to remove the large amounts of water absorbed by the fabric during dyeing and rinsing.

[0003] However, traditional tie-dyed fabrics have extremely high moisture content after soaking and washing, resulting in a significant increase in overall weight. Currently available dehydration equipment often requires operators to manually pull the heavy, wet fabric from deep within the tub after dehydration. This manual operation is not only extremely labor-intensive, easily causing back injuries to workers, but also inefficient for large-sized and batch-produced tie-dyed fabrics, severely impacting the subsequent drying and tumble-drying processes. Furthermore, stacking the fabric together during removal hinders the rapid evaporation of surface moisture.

[0004] On the other hand, existing dehydration equipment typically has a direct connection to the drain pipe in its drainage design. In actual use, if the external drain pipe becomes blocked or negative pressure fluctuations occur, the wastewater accumulated in the transport pipe is very likely to flow back and re-enter the dehydration drum. This not only re-contaminates the cleaned fabric that has already been dehydrated, but also causes bacteria to grow inside the equipment, affecting product quality.

[0005] Therefore, this utility model proposes a rapid dehydration device for tie-dyeing textile fabrics to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems existing in the dehydration equipment for tie-dye textile fabrics, such as the heavy weight of the tie-dyed fabric after absorbing water, making manual extraction difficult, labor-intensive and inefficient, and the easy backflow of sewage into the equipment and contaminating the fabric under negative pressure or blockage, this utility model aims to provide a rapidly dehydrating equipment for tie-dye textile fabrics with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a rapid dehydration device for tie-dyeing textile fabrics, including: a base and a dehydration group disposed on the top of the base, the bottom of the dehydration group being connected to a transport pipe; a suspension mechanism disposed outside the dehydration group and an anti-backflow mechanism disposed at the bottom of the dehydration group.

[0008] The suspension mechanism includes two support frames fixedly connected to the top sides of the base and a housing fixedly connected to the top of the two support frames. A drive assembly is provided inside the housing. The drive assembly includes a motor fixedly connected to the inner wall of the housing. A rotating shaft is fixedly connected to the output end of the motor. A rotating roller is fixedly connected to the outer surface of the rotating shaft. Another rotating roller is driven to the outer surface of the rotating shaft through a belt assembly. The belt assembly is rotatably connected to the inner wall of the housing.

[0009] Furthermore, the dehydration unit and the transport pipe are connected and combined through the anti-backflow mechanism. The anti-backflow mechanism includes a fixed pipe connecting the bottom of the dehydration unit and the transport pipe. A fixed ring is fixedly connected to the inner wall of the fixed pipe. A telescopic shaft is fixedly connected to the bottom of the fixed ring. A sliding plate is fixedly connected to the bottom of the telescopic shaft. A sealing plug is fixedly connected to the bottom of the sliding plate. A spring is sleeved on the outer surface of the telescopic shaft. The two ends of the spring abut against the bottom of the fixed ring and the top of the sliding plate, respectively. In the natural state of the spring, the sealing plug seals against the bottom outlet of the fixed pipe.

[0010] Preferably, the suspension mechanism further includes a lifting ring fixedly connected to the bottom of the outer shell. The lifting ring is located between the two rotating rollers and directly above the dehydration unit. The lifting ring helps the fabric stay centered during the lifting process, preventing the fabric from swinging too much and affecting the transmission stability after dehydration. It also helps to gather multiple strands of fabric together.

[0011] Preferably, the suspension mechanism further includes a fixing block fixedly connected to the top inner side of the support frame. The bottom of the fixing block is rotatably connected to the shaft of another rotating roller. The fixing block provides a stable support point for the rotating roller at the end away from the motor, which can share the radial load on the shaft, prevent the shaft from bending and deforming due to excessive fabric weight, and ensure the long-term reliability of the transmission mechanism.

[0012] Preferably, the main body of the rotating roller is a combination of a frustum-shaped cone that is thinner in the middle and thicker at both ends, i.e., a hyperbolic funnel-shaped structure. This specific shape can utilize the self-centering effect of the fabric during the movement process to automatically shrink the fabric passing through the surface of the rotating roller towards the middle, effectively preventing the fabric from slipping off the edge of the rotating roller, and realizing the limiting and guiding function of the transmitted fabric.

[0013] Preferably, the anti-backflow mechanism further includes a cap inserted into the top of the fixed pipe. The cap is tightly fitted to the inner wall of the fixed pipe on its outer surface. The cap serves as a manually controlled primary valve to completely seal the upper inlet of the fixed pipe when the equipment is performing dehydration or soaking operations, ensuring good airtight water storage capacity inside the equipment during non-drainage stages.

[0014] Preferably, the diameter of the sealing plug is larger than the diameter of the inlet of the transport pipe. The sealing plug is used to seal the transport pipe under the elastic force of the spring. By using the large-diameter sealing plug to cover the small-diameter inlet, a reliable surface contact seal can be formed. Compared with the line contact seal, it has a better fault tolerance and sealing effect, and further eliminates the risk of reverse leakage of sewage under pressure fluctuations.

[0015] Preferably, a gap is formed between the fixed ring, the sliding plate, and the sealing plug to allow water to flow through. When the cover is opened and water flows through, the sliding plate can overcome the elastic force of the spring and move downward in the vertical direction. This structural design utilizes the principle of fluid mechanics to convert the gravitational potential energy of the water flow into the mechanical kinetic energy that pushes the valve core to open, thereby realizing the automated control of the drainage process.

[0016] Preferably, the dehydration unit includes an outer barrel and an inner barrel rotatably connected to the inside of the outer barrel. The side wall of the inner barrel has several through holes, and the fixed pipe is connected to the lowest point of the bottom of the outer barrel. This connection position design follows the principle of gravity flow, which can ensure that the water after dehydration naturally converges to the outlet under the action of gravity, avoiding the growth of bacteria due to residual water at the bottom of the barrel.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problems of heavy weight, difficult manual extraction, and high labor intensity of tie-dyed fabrics after absorbing water by setting up a suspension mechanism and using a motor to drive the rotating rollers to rotate and cooperate with the belt assembly to achieve synchronous transmission of the two rollers. It achieves the effect of mechanized and automatic assisted extraction of fabrics. At the same time, the fabric can fully contact the air during the suspension transportation process, which further dries the fabric and improves the efficiency and convenience of fabric processing.

[0018] 2. This utility model, by setting an anti-backflow mechanism, utilizes the balance between the gravity of the water flow and the elastic force of the spring to solve the problem of sewage backflow and contamination of the equipment in the existing technology. It achieves the effect of automatic opening and discharge when there is water and automatic resetting and sealing when there is no water, effectively preventing sewage from flowing back in the transport pipe and ensuring the cleanliness and hygiene of the dehydration unit.

[0019] 3. This utility model solves the problem of fabric deviation or slippage during transmission by designing the rotating roller as a hyperbolic funnel-shaped structure that is thinner in the middle and thicker at both ends. It achieves the effect of automatically guiding and limiting the fabric using the self-centering principle, thus ensuring the stability and reliability of fabric transmission.

[0020] 4. This utility model solves the problem of fabric swaying or failing to accurately enter the transmission area during the lifting process by setting lifting rings between the rotating rollers, thereby achieving the effect of auxiliary guidance and gathering of the fabric and further improving the stability of fabric transportation.

Detailed Implementation

[0023] Example: Reference Figures 1 to 5 This utility model provides a rapid dehydration device for tie-dyeing textile fabrics, which aims to solve the problems in the prior art where tie-dyed fabrics are heavy after absorbing water and difficult to extract manually, and the wastewater generated during dehydration is prone to backflow and contamination of the equipment during discharge.

[0024] like Figure 1 and Figure 2 As shown, the rapid dehydration equipment for tie-dyeing textile fabrics includes a base 1 and a dehydration unit 2 fixedly connected to the top of the base 1. The bottom of the dehydration unit 2 is connected to a transport pipe 5. The base 1 serves as the load-bearing foundation of the entire equipment to maintain the stability of the equipment when it is placed. The dehydration unit 2 is used to hold the fabric and perform dehydration treatment. The transport pipe 5 is used to discharge the dehydrated water to a designated area.

[0025] The equipment also includes a suspension mechanism 3 located outside the dewatering unit 2, and an anti-backflow mechanism 4 located at the bottom of the dewatering unit 2. The suspension mechanism 3 is used to assist in lifting and air-drying the fabric after dewatering, and the anti-backflow mechanism 4 is used to control the flow of drainage and prevent sewage from flowing back into the dewatering unit 2.

[0026] The suspension mechanism 3 includes two support frames 31, which are fixedly connected to the top sides of the base 1 and extend vertically to a position higher than the dehydration group 2. A housing 32 is fixedly connected between the tops of the two support frames 31. The housing 32 spans across the dehydration group 2 and is used to install the drive components and to provide dust protection for the internal structure.

[0027] like Figure 3 As shown, a drive assembly 33 is fixedly connected inside the housing 32. The drive assembly 33 includes a motor 331, which is fixedly connected to one side of the inner wall of the housing 32. The motor 331 is used to provide rotational power. A rotating shaft 332 is fixedly connected to the output end of the motor 331. The rotating shaft 332 extends horizontally along the length of the housing 32. A rotating roller 34 is fixedly connected to the outer surface of the rotating shaft 332. The rotating roller 34 rotates synchronously with the rotating shaft 332.

[0028] The outer surface of the rotating shaft 332 is also connected to another rotating roller 34 via a belt assembly 333. The belt assembly 333 is rotatably connected to the inner wall of the outer casing 32 and is used to transmit the power of the motor 331 to the rotating roller 34 at the far end, so that the two rotating rollers 34 can rotate synchronously in the same direction, thereby coordinating to complete the traction action of the fabric.

[0029] like Figure 4 and Figure 5 As shown, the anti-backflow mechanism 4 includes a fixed pipe 41. The upper end of the fixed pipe 41 is connected to the bottom of the dehydration unit 2, and the lower end is connected to the transport pipe 5. The fixed pipe 41 serves as the main drainage channel, and a fixed ring 43 is fixedly connected to its inner wall. The fixed ring 43 is used to provide mounting points for the internal moving components.

[0030] A telescopic shaft 44 is fixedly connected to the bottom of the fixed ring 43. A sliding plate 46 is fixedly connected to the bottom end of the telescopic shaft 44. The sliding plate 46 can move up and down along the axis of the telescopic shaft 44. A sealing plug 47 is fixedly connected to the bottom of the sliding plate 46. The sealing plug 47 is used to block the drain outlet. A spring 45 is sleeved on the outer surface of the telescopic shaft 44.

[0031] The two ends of the spring 45 abut against the bottom of the fixed ring 43 and the top of the sliding plate 46 respectively. The spring 45 is in a compressed or naturally extended state to provide a downward restoring force or an upward pulling force. Specifically, it is configured to keep the sealing plug 47 always in an upward or downward trend to fit the sealing surface in the natural state. In this embodiment, it is configured to seal against the bottom outlet of the fixed pipe 41 in the natural state.

[0032] Reference Figure 1 , Figure 2 and Figure 3 The suspension mechanism 3 mainly includes a housing 32 and a drive assembly 33 located inside the housing 32. The housing 32 is fixedly connected to the base 1 above by support frames 31 at both ends, spanning directly above the dehydration unit 2, providing sufficient vertical space for fabric extraction.

[0033] A lifting ring 35 is fixedly connected to the bottom of the outer casing 32. The lifting ring 35 is located between the two rotating rollers 34 and directly above the dewatering group 2. Its axis is coplanar with the central axis of the dewatering group 2. The lifting ring 35 is used for the fabric to pass through and plays a guiding and gathering role during the fabric lifting process. It prevents the fabric from shifting or swinging during the lifting process and ensures that the fabric can enter the working area of ​​the rotating roller 34 smoothly.

[0034] A fixing block 36 is fixedly connected to the top inner side of the support frame 31. The bottom of the fixing block 36 is rotatably connected to the shaft of another rotating roller 34. The fixing block 36 is used to provide an additional support point for the rotating roller 34 at the end away from the motor 331, ensuring that the rotating roller 34 can keep its axis horizontal when it is pulled by the weight of the fabric, avoiding tilting or jamming due to unilateral force, thereby improving the stability of the transmission.

[0035] The main body of the rotating roller 34 is a combination of a truncated cone with a thinner middle and thicker ends, i.e. a hyperbolic funnel-shaped structure. This specific shape design utilizes the self-centering principle. When the fabric passes over the surface of the rotating roller 34, it will automatically shrink and gather towards the middle position with a smaller diameter, thereby limiting and guiding the fabric and preventing the fabric from slipping off the edge of the rotating roller 34 during rotation.

[0036] During operation, the motor 331 in the drive assembly 33 starts, driving the rotating shaft 332 to rotate, which in turn directly drives the active rotating roller 34, which is fixedly connected to the rotating shaft 332, to rotate. At the same time, the rotational power is transmitted to the passive rotating roller 34 through the belt assembly 333 set on the inner wall of the housing 32, so that the two rotating rollers 34 rotate synchronously. With the guidance of the hanging ring 35, the friction between the surface of the rotating roller 34 and the fabric is used to smoothly and effortlessly lift the dehydrated fabric from the dehydration group 2. During the process of hanging and moving in the air, the contact area with the air is increased, and a further air-drying effect is achieved.

[0037] Regarding the specific selection of the motor 331 in the drive component 33 and the control circuit, those skilled in the art can use conventional methods such as servo motors and stepper motors according to actual load requirements. Its specific internal structure is a well-known technology in the field and will not be described in detail here.

[0038] As a preferred embodiment, to address the problem of wastewater generated during dewatering easily flowing back and contaminating the interior of the dewatering unit 2 during discharge, this invention includes an anti-backflow mechanism 4, such as... Figure 4 and Figure 5 As shown, the core of the anti-backflow mechanism 4 is to automatically control the opening and closing of the drainage channel by utilizing the balance between the gravity of the water flow and the mechanical elasticity. The anti-backflow mechanism 4 includes a fixed pipe 41 connected between the bottom of the dehydration unit 2 and the transport pipe 5, and a fixed ring 43 is fixedly connected to the inner wall of the fixed pipe 41.

[0039] A telescopic shaft 44 is fixedly connected to the bottom of the fixed ring 43. A sliding plate 46 is fixedly connected to the bottom end of the telescopic shaft 44. A sealing plug 47 is fixedly connected to the bottom of the sliding plate 46. The sealing plug 47 is used to directly block the inlet of the transport pipe 5. A spring 45 is sleeved on the outer surface of the telescopic shaft 44. The two ends of the spring 45 abut against the bottom of the fixed ring 43 and the top of the sliding plate 46, respectively. In the natural state of the spring 45, the sealing plug 47 seals against the bottom outlet of the fixed pipe 41, thereby cutting off the drainage passage.

[0040] As a further preferred embodiment, in order to reliably prevent water leakage when the fabric needs to be soaked in water, the anti-backflow mechanism 4 also includes a cover 42 inserted into the top of the fixed tube 41. The outer surface of the cover 42 is tightly fitted to the inner wall of the fixed tube 41. The cover 42 controls the opening and closing of the upper inlet of the fixed tube 41 by manually inserting and removing it. The cover 42 needs to be tightened before the dehydration operation and pulled out during the drainage operation.

[0041] To ensure that the sealing plug 47 has good sealing performance, the diameter of the sealing plug 47 is larger than the inlet diameter of the transport pipe 5, so that the sealing plug 47 can completely cover the edge of the inlet of the transport pipe 5 under the downward elastic force of the spring 45, forming a surface contact seal, effectively preventing sewage in the transport pipe 5 from flowing back into the fixed pipe 41 due to negative pressure or other reasons.

[0042] To achieve automatic drainage, a gap is formed between the fixed ring 43, the sliding plate 46, and the sealing plug 47 for water to flow through. When the cover 42 is opened and a large amount of water flows through the fixed pipe 41, the gravity pressure generated by the water flow is applied to the sealing plug 47 and the sliding plate 46. This pressure is sufficient to overcome the elastic force of the spring 45, allowing the sliding plate 46 to move vertically downward along the axis of the telescopic shaft 44, thereby opening the sealing fit between the sealing plug 47 and the outlet of the fixed pipe 41, allowing sewage to be smoothly discharged into the transport pipe 5.

[0043] To improve dehydration efficiency and ensure smooth drainage of accumulated water, the dehydration unit 2 includes an outer barrel and an inner barrel rotatably connected to the inside of the outer barrel. The side wall of the inner barrel has several through holes arranged in an array to throw out water under centrifugal force. The fixed pipe 41 is connected to the lowest point of the bottom of the outer barrel and uses gravity to collect all the accumulated water to the fixed pipe 41 to avoid water remaining in the barrel.

[0044] The working principle is as follows: When using it, first place the dehydration unit 2 stably on the ground with the support of the base 1, and put the wet fabric to be treated into the inner barrel of the dehydration unit 2.

[0045] Before the dehydration operation begins, ensure that the cap 42 is tightly inserted into the top of the fixed tube 41. At this time, the anti-backflow mechanism 4 is in the closed state to prevent untreated liquid from flowing out.

[0046] Start the dehydration unit 2 to dehydrate the internal fabric. After dehydration, manually pull one end of the fabric upwards so that it passes through the two rotating rollers 34 and the hanging ring 35 on the support frame 31 in sequence.

[0047] Then, the motor 331 in the drive assembly 33 inside the housing 32 is started. The motor 331 drives the rotating shaft 332 to rotate, which in turn drives the active rotating roller 34 fixedly connected to it to rotate. At the same time, the rotation of the rotating shaft 332 is transmitted to the passive rotating roller 34 at the other end through the belt assembly 333, so that the two rotating rollers 34 rotate synchronously in the same direction.

[0048] Utilizing the friction between the surface of the rotating roller 34 and the fabric, as well as the guiding effect of the hyperbolic funnel-shaped structure, and with the limiting effect of the hanging ring 35, the fabric is smoothly and continuously lifted from the dehydration unit 2 and transported to the next step area. During this process, the suspended transport method allows the fabric to unfold in the air, increasing the contact area with the air, thereby achieving a further drying effect.

[0049] When it is necessary to drain the dehydrated water, the cover 42 is manually pulled out from the fixed pipe 41, and the wastewater accumulated at the bottom of the outer barrel of the dehydration unit 2 flows downward through the fixed pipe 41.

[0050] Under the influence of the water flow's own gravity, water pressure is applied to the sealing plug 47 and the sliding plate 46, forcing the sliding plate 46 to overcome the elastic force of the spring 45 and move downward along the telescopic shaft 44. At this time, the sealing plug 47 leaves the inlet position of the transport pipe 5, opening the drainage channel. Sewage flows through the gap between the fixed ring 43, the sliding plate 46 and the pipe wall to the transport pipe 5 and is discharged.

[0051] Once the water in the fixed pipe 41 is drained, the downward pressure generated by the water flow disappears. The spring 45 uses its own elastic restoring force to drive the sliding plate 46 and the sealing plug 47 to return to their original position, so that the sealing plug 47 re-seals and abuts against the outlet of the fixed pipe 41, thereby automatically cutting off the connection and preventing the residual sewage in the transport pipe 5 from flowing back into the dewatering group 2 due to external factors, thus ensuring the cleanliness and hygiene of the equipment.
