Description

Technical Field

[0001] This utility model relates to the field of washing equipment technology, specifically a low-tension, flat-width, continuous desizing and washing equipment. Background Technology

[0002] In the process of the textile industry moving towards high-end and green development, the pretreatment quality of flat-width fabrics is the cornerstone of the entire industrial chain. Among them, the desizing and washing processes are particularly critical, as they directly determine the uniformity of subsequent dyeing and the intrinsic quality of the final product. The core pursuit of this process is always to achieve a perfect balance between "cleaning the fabric" and "protecting the fabric"—that is, to achieve the highest processing efficiency with the lowest mechanical tension. Excessive tension will damage the elasticity of the fabric and cause deformation that is difficult to recover, becoming a bottleneck in the production of high-quality, highly sensitive fabrics. Inefficient cleaning means huge consumption of energy such as water, electricity, and steam, which runs counter to the requirements of the era of sustainable development.

[0003] In the prior art, such as the authorized utility model patent with authorization announcement number CN203947319U, a high-efficiency and low-water-consumption desizing and washing machine is disclosed. By setting a centrifugal drum at the top of the washing tank, centrifugal force is used to spray water onto the fabric for cleaning, and an ultrasonic oscillator and a blower are used to generate bubbles in order to achieve the purpose of high efficiency and low water consumption. However, when such equipment is used, it relies on the coordinated operation of multiple transmission and power systems such as centrifugal drum, water pump, ultrasonic oscillator and blower, which is relatively complex in structure. This not only increases the cost and maintenance difficulty, but its inherent multi-power source structure also leads to complex control and high energy consumption. Moreover, most of the complex transmission mechanisms integrated inside the equipment are traction-type transmissions aimed at maintaining the continuous and taut movement of the fabric. During the fabric movement, the warp tension of the fabric is significantly increased, which can easily lead to the stretching and deformation of the fabric. Therefore, we propose a low-tension flat-width continuous desizing and washing equipment. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a low-tension, flat-width, continuous desizing and washing device, comprising a mounting box. A throat pipe is fixedly installed inside the mounting box, with an upstream pipe and a downstream pipe installed at both ends of the throat pipe, respectively. Side pipes are embedded in the side walls of both the upstream and downstream pipes, and the side pipes are inclined. A fixing frame is fixedly installed inside the side pipe, and a piston is slidably sleeved on the fixing frame. A retaining ring is fixedly installed inside the side pipe, and two sets of symmetrically distributed first springs are sleeved on the fixing frame. The two ends of the two sets of first springs are fixedly connected to the piston and the fixing frame, respectively.

[0005] In some embodiments, the retaining ring can be movably engaged with the piston, and the retaining ring is located on the outside of the piston.

[0006] In some embodiments, the mounting box is slidably mounted with a mounting rod, a first traction rod is slidably mounted inside the mounting rod, a second traction rod is slidably mounted inside the first traction rod, a connecting rod is rotatably mounted on the mounting rod, a crank is rotatably mounted inside the mounting box, the crank is rotatably connected to the end of the connecting rod away from the mounting rod via a rotating shaft, and a sliding rod is fixedly mounted inside the mounting box.

[0007] In some embodiments, the mounting rod is slidably sleeved with the slide rod, and two sets of symmetrically distributed second springs are sleeved on the slide rod, with the two ends of the two sets of second springs respectively fixedly connected to the mounting rod and the mounting box.

[0008] In some embodiments, a positioning block is fixedly installed at the end of the second traction rod away from the mounting rod, a positioning plate is rotatably installed on the positioning block, the positioning plate is rotatably connected to the positioning block through a mounting shaft, two sets of symmetrically distributed torsion springs are sleeved on the mounting shaft, the two ends of the two sets of torsion springs are fixedly connected to the positioning block and the positioning plate respectively, and a rubber pad is fixedly adhered to the positioning plate.

[0009] In some embodiments, a threaded rod is rotatably installed inside the mounting rod, the threaded rod passing through and threadedly connected to the first traction rod, and a threaded tube is rotatably installed inside the first traction rod, the threaded tube passing through and threadedly connected to the second traction rod.

[0010] In some embodiments, the threaded rod is provided with two sets of symmetrically distributed sliding grooves, and the two sets of threaded tubes are provided with two sets of symmetrically distributed sliders. The sliders are arranged correspondingly to the sliding grooves, and the threaded tubes are slidably sleeved with the threaded rod through the sliders and sliding grooves.

[0011] This utility model has at least the following beneficial effects:

[0012] 1. By setting up a throat, upstream pipe, and downstream pipe inside the installation box, and connecting an inclined side pipe to its side wall, the piston and spring structure inside the side pipe can generate pulsation using the pressure of the water flow itself. When the water flows through the throat, the Venturi effect is generated due to the change in pipe diameter, the flow rate increases and the pressure decreases, thereby automatically drawing in air through the side pipe and forming a large number of bubbles. This allows the fabric to be continuously impacted by the pulsating water flow and fine bubbles at the same time when passing through the pipe, which effectively improves the peeling ability of the sizing agent. The whole process does not rely on an additional blower or a complex oscillating roller drive mechanism, which simplifies the equipment structure to a certain extent.

[0013] 2. By setting up a telescopic linkage mechanism consisting of an installation rod, a first traction rod, and a second traction rod, and cooperating with a crank and a slide rod, the fabric can be moved smoothly while continuously and regularly reciprocating. The shaking action is directly transmitted to the fabric section passing through the throat, upstream pipe, and downstream pipe. In the high-speed water flow and bubble environment generated by the Venturi effect, the fabric is not only impacted by the fluid, but the mechanical rubbing action between the fabric fibers and the cleaning medium is also increased. This effectively compensates for the cleaning blind spots that may exist when relying solely on fluid flushing. In particular, it helps to loosen and remove tightly bound slurry impurities. The entire process is completed under low tension traction, and the fabric does not need to bear additional tension force. This achieves a unity of mechanical action and low tension protection. Without introducing a complex transmission system and additional energy consumption, the overall cleaning efficiency of the equipment is further consolidated and improved.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please refer to Figure 1-5 This utility model provides a technical solution: a low-tension, flat-width continuous desizing and washing device, including a mounting box 1. A throat pipe 3 is fixedly installed inside the mounting box 1. An upstream pipe 2 and a downstream pipe 25 are respectively installed at both ends of the throat pipe 3. The side walls of the upstream pipe 2 and the downstream pipe 25 are embedded in side pipes 4. The side pipes 4 are inclined. A fixing frame 5 is fixedly installed inside the side pipes 4. A piston 7 is slidably sleeved on the fixing frame 5. A retaining ring 6 is fixedly installed inside the side pipes 4. Two sets of symmetrically distributed first springs 8 are sleeved on the fixing frame 5. The two ends of the two sets of first springs 8 are fixedly connected to the piston 7 and the fixing frame 5 respectively. The retaining ring 6 can be movably engaged with the piston 7. The retaining ring 6 is located outside the piston 7. When the main circulating water pump... As the water flows through the upstream pipe 2 to the throat pipe 3 and then to the downstream pipe 25, the water flow speed increases and the pressure decreases due to the narrowing of the channel at the throat pipe 3. The side pipe 4, due to its inclined installation and the presence of a piston 7 and a first spring 8 assembly inside, responds to this pressure change. When the water pressure is high, it pushes the piston 7 to compress the first spring 8 and move it inward. When the pressure drops as it flows through the throat pipe 3, the first spring 8 pushes the piston 7 to return to its original position. This reciprocating motion can periodically open and close the channel between the side pipe 4 and the main water channel. On the one hand, it utilizes the Venturi effect to automatically draw in air to form fine bubbles, and on the other hand, it generates beneficial pulsations in the water flow, which together act on the fabric to improve the sizing peeling effect.

[0022] Example 2: Please refer to Figure 4 , Figure 5 The mounting box 1 has a sliding mounting rod 9, a first traction rod 10, and a second traction rod 11. A connecting rod 23 is rotatably mounted on the mounting rod 9. A crank 24 is rotatably mounted inside the mounting box 1, and the crank 24 is rotatably connected to the end of the connecting rod 23 away from the mounting rod 9 via a pivot. A sliding rod 21 is fixedly mounted inside the mounting box 1, and the mounting rod 9 and the sliding rod 21 are slidably sleeved together. Two sets of symmetrically distributed second springs 22 are sleeved on the sliding rod 21, and the two ends of the two sets of second springs 22 are fixedly connected to the mounting rod 9 and the mounting box 1, respectively. When an external power drives the crank 24 to rotate, it will drive the mounting rod 9 to reciprocate linearly along the sliding rod 21 through the connecting rod 23. The second springs 22 on the mounting rod 9 play a role in buffering and assisting in resetting, ensuring smooth movement. The reciprocating motion of the mounting rod 9 is transmitted to the first traction rod 10 and the second traction rod 11 nested inside it, which ultimately causes the fabric clamping component connected to the end of the second traction rod 11 to produce a regular back-and-forth shaking, thereby giving the fabric a mechanical oscillation effect that helps to loosen the sizing while pulling the fabric forward continuously.

[0023] A positioning block 16 is fixedly installed at the end of the second traction rod 11 away from the mounting rod 9. A positioning plate 17 is rotatably installed on the positioning block 16. The positioning plate 17 is rotatably connected to the positioning block 16 through the mounting shaft 19. Two sets of symmetrically distributed torsion springs 20 are sleeved on the mounting shaft 19. The two ends of the two sets of torsion springs 20 are fixedly connected to the positioning block 16 and the positioning plate 17, respectively. A rubber pad 18 is fixedly adhered to the positioning plate 17. When clamping the fabric, the operator can rotate the positioning plate 17 to place the edge of the fabric between the positioning block 16 and the positioning plate 17. Under the restoring force of the torsion springs 20, the positioning plate 17 will automatically press against the positioning block 16, thereby working together with the rubber pad 18 to gently and stably clamp the edge of the fabric. This design provides sufficient clamping force to prevent the fabric from slipping during operation. At the same time, its flexible clamping method and rotatable structure can adapt to fabrics of different thicknesses and avoid causing hard damage to the fabric.

[0024] A threaded rod 12 is rotatably installed inside the mounting rod 9. The threaded rod 12 passes through the first traction rod 10 and is threadedly connected to the first traction rod 10. A threaded tube 14 is rotatably installed inside the first traction rod 10. The threaded tube 14 passes through the second traction rod 11 and is threadedly connected to the second traction rod 11. Two sets of symmetrically distributed sliding grooves 13 are provided on the threaded rod 12. Two sets of symmetrically distributed sliders 15 are provided inside the two sets of threaded tubes 14. The sliders 15 are correspondingly arranged with the sliding grooves 13. The threaded tubes 14 are slidably sleeved with the threaded rod 12 through the sliders 15 and the sliding grooves 13. This telescopic adjustment mechanism is used for flexible adjustment. The entire length of the traction rod assembly is such that when the threaded rod 12 is rotated, the first traction rod 10 will extend or retract relative to the mounting rod 9 due to the threaded connection. At the same time, since the threaded tube 14 cooperates with the sliding groove 13 on the threaded rod 12 through the internal slider 15, the two can rotate synchronously and slide relative to each other. When the threaded tube 14 is rotated, the second traction rod 11 will extend or retract relative to the first traction rod 10. By adjusting in steps, the position of the clamping component at the end of the second traction rod 11 can be precisely controlled to adapt to different equipment layouts and fabric threading path requirements.
