Description

Technical Field

[0001] This utility model relates to the technical field of alkaline spraying devices, and in particular to an alkaline spraying device for the production of self-cleaning, wash-free fabrics. Background Technology

[0002] An alkaline spraying device is a specialized piece of equipment used in fabric production to treat cotton fibers by spraying alkaline solutions. It can be broadly defined as a device that uses a pump to deliver alkaline solutions to spraying components, where pressure causes the solutions to be sprayed out in a mist or liquid column, achieving uniform wetting of the fabric. Specifically, this device typically consists of an alkaline storage tank, delivery pipes, spray heads, a control system, and a supporting structure. During operation, the alkaline solution is delivered to the spray heads via pipes and, under pressure, evenly covers the fabric surface.

[0003] Currently, most alkali spraying devices have symmetrically arranged guide pipes fixed at the top. This fixed structure presents significant adjustment difficulties in practical applications. Because the guide pipes are rigidly connected to the top of the device, their height cannot be flexibly adjusted according to fabric thickness and spraying process requirements. When processing fabrics of different specifications, the fixed-height guide pipes struggle to balance spray uniformity and alkali utilization: if the spray height is too high, the alkali atomized solution will spread too widely, with some alkali splashing outside the device before contacting the fabric; if the height is too low, fluctuations during fabric operation may cause direct friction between the guide pipe and the fabric, damaging the fiber structure. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to provide an alkaline spraying device for the production of self-cleaning, wash-free fabrics, in order to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides an alkaline spraying device for the production of self-cleaning, wash-free fabrics, comprising a spray tank, wherein a plurality of linearly arrayed guide rollers are rotatably connected inside the spray tank, two symmetrically arranged hydraulic cylinders are fixedly connected to both the front and rear sides of the spray tank, and a guide frame is fixedly connected to the output ends of the plurality of hydraulic cylinders. A plurality of linearly arrayed U-shaped frames are fixedly installed on the top of the guide frame by bolts, and two symmetrically arranged electric push rods are fixedly connected to the top of each U-shaped frame. A lifting frame is fixedly connected to the output ends of the two electric push rods, and a spray pipe is fixedly installed at the bottom of the lifting frame by clamps. A plurality of linearly arrayed spray heads are fixedly connected to the bottom of the spray pipe, and a corrugated telescopic hose is fixedly connected to the bottom of the spray pipe. The bottom end of the corrugated telescopic hose is fixedly connected to the guide frame by a flange, and threaded sleeves are fixedly connected to both the left and right ends of the spray pipe. Both threaded sleeves are slidably connected to the U-shaped frames, and a locking bolt is threadedly connected to the inner wall of each threaded sleeve. The nuts of both locking bolts are fitted into the U-shaped frames.

[0007] Preferably, in any of the above solutions, the U-shaped frame has slots extending through both its front and rear sides, and the two threaded sleeves are slidably connected to the U-shaped frame through the slots.

[0008] Preferably, in any of the above schemes, the inner wall of the guide frame is fixedly connected with a plurality of symmetrically arranged limiting plates, and the plurality of limiting plates are slidably connected to the spray tank.

[0009] Preferably, one side of the flow guide frame has two symmetrically arranged water inlet pipes fixedly connected to it, and the two water inlet pipes are connected to the corrugated telescopic hose through the flow guide frame.

[0010] Preferably, in any of the above schemes, the plurality of U-shaped frames are perpendicular to the guide frame, the plurality of spray heads correspond to the spray pool, and the plurality of spray heads are connected to the corrugated telescopic hose through the spray pipe.

[0011] Preferably, in any of the above solutions, the top surface of the lifting frame is fixedly connected to two symmetrically arranged guide rods, the two electric push rods are located between the two guide rods, and the two guide rods are slidably connected to the U-shaped frame.

[0012] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0013] 1. The dual lifting structure of electric push rods and hydraulic cylinders allows for flexible adjustment of the height and position of the spray pipes, solving the problem of traditional fixed guide pipes being unable to adapt to different fabric thicknesses. Specifically, the hydraulic cylinder drives the guide frame to move up and down, achieving overall height adjustment of multiple spray pipes. The electric push rod on each U-shaped frame can independently control the vertical position of the lifting frame and spray pipes, forming a dual adjustment mode of "overall + local". When processing thick canvas, the overall height of the guide frame can be raised using the hydraulic cylinder, and the height of each spray pipe can be finely adjusted using the electric push rod to avoid friction between the spray head and the fabric. When processing thin gauze, the guide frame is lowered and the height of the spray pipes is adjusted individually, ensuring that the alkali solution is sprayed evenly at a suitable distance. This guarantees spray uniformity, improves alkali solution utilization, and avoids splashing waste or fiber damage caused by improper height.

[0014] 2. The adjustable installation structure of the spray pipe, in conjunction with the corrugated telescopic hose, enables flexible adjustment and reliable connection of the spray pipe's lateral position. The threaded sleeve slides on the U-shaped frame through the groove, and the locking bolts can fix the lateral position of the spray pipe to meet the spraying needs of fabrics of different widths. Simultaneously, the corrugated telescopic hose connects the spray pipe to the guide frame, allowing free expansion and contraction during lateral movement or lifting of the spray pipe. This ensures smooth delivery of the alkali solution while preventing the rigid pipe from breaking due to frequent movement. This design allows the spray pipe to be precisely positioned according to the fabric width and spraying process requirements, solving the problem that traditional fixed guide pipes cannot adapt to different fabric specifications, thus improving the versatility of the device and the flexibility of spraying operations.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0023] like Figures 1 to 6 As shown, an alkaline spraying device for the production of self-cleaning, wash-free fabrics includes a spray tank 1. Several linearly arrayed guide rollers 2 are rotatably connected inside the spray tank 1. Two symmetrically arranged hydraulic cylinders 3 are fixedly connected to both the front and rear sides of the spray tank 1. A guide frame 4 is fixedly connected to the output ends of the hydraulic cylinders 3. Several linearly arrayed U-shaped frames 5 are bolted to the top of the guide frames 4. Two symmetrically arranged electric push rods 6 are fixedly connected to the top of each U-shaped frame 5. A lifting frame is fixedly connected to the output ends of the two electric push rods 6. 7. A spray pipe 8 is fixedly installed at the bottom of the lifting frame 7 by clamps. Several linear array spray heads 9 are fixedly connected to the bottom of the spray pipe 8. A corrugated telescopic hose 10 is fixedly connected to the bottom of the spray pipe 8. The bottom end of the corrugated telescopic hose 10 is fixedly connected to the guide frame 4 by a flange. Threaded sleeves 11 are fixedly connected to both the left and right ends of the spray pipe 8. Both threaded sleeves 11 are slidably connected to the U-shaped frame 5. A locking bolt 12 is threadedly connected to the inner wall of each threaded sleeve 11. The nuts of both locking bolts 12 are in contact with the U-shaped frame 5.

[0024] As an optional technical solution of this utility model, slots 13 are provided through both the front and rear sides of the U-shaped frame 5. Two threaded sleeves 11 are slidably connected to the U-shaped frame 5 through the slots 13. The slots 13 on the front and rear sides of the U-shaped frame 5 and the threaded sleeves 11 slide in cooperation, allowing the spray pipe 8 to move laterally along the slots 13. This enables flexible adjustment of the lateral position of the spray pipe 8 according to the width of the fabric. When processing fabrics of different widths, simply sliding the threaded sleeves 11 and fixing them with locking bolts 12 ensures that the spray head 9 is precisely aligned with the fabric, ensuring uniform spraying of the alkali solution and avoiding uneven fabric treatment caused by spray position deviation. This improves the adaptability of the device to fabrics of different specifications.

[0025] As an optional technical solution of this utility model, a plurality of symmetrically arranged limiting plates 14 are fixedly connected to the inner wall of the guide frame 4. Each limiting plate 14 is slidably connected to the spray tank 1. The slidable connection between the limiting plates 14 on the inner wall of the guide frame 4 and the spray tank 1 guides and limits the lifting and lowering process of the guide frame 4, ensuring that the guide frame 4 moves smoothly up and down under the drive of the hydraulic cylinder 3, avoiding shaking or deviation. At the same time, the limiting plates 14 also enhance the stability of the guide frame 4 installation, ensuring its accurate position during spraying operations, thereby maintaining the correct spraying position of the spray pipe 8 and the spray head 9, and ensuring the reliability of the alkaline solution spraying.

[0026] As an optional technical solution of this utility model, two symmetrically arranged water inlet pipes 15 are fixedly connected to one side of the guide frame 4. The two water inlet pipes 15 are connected to the corrugated telescopic hose 10 through the guide frame 4. The water inlet pipe 15 on one side of the guide frame 4 is connected to the corrugated telescopic hose 10 through the guide frame 4, providing a stable channel for the delivery of alkali solution. The water inlet pipe 15 can be connected to an external alkali solution supply system, so that the alkali solution enters the guide frame 4 through the water inlet pipe 15, and is then delivered to the spray pipe 8 and spray head 9 through the corrugated telescopic hose 10, ensuring that the alkali solution can be continuously and smoothly supplied to the spray position to meet the needs of fabric spraying treatment. At the same time, this connection method also facilitates the installation and disassembly of the water inlet pipe 15 and the external system.

[0027] As an optional technical solution of this utility model, several U-shaped frames 5 are perpendicular to the guide frame 4, several spray heads 9 correspond to the spray tank 1, and several spray heads 9 are connected to the corrugated telescopic hose 10 through spray pipes 8. The U-shaped frames 5 are set perpendicular to the guide frame 4, and the spray heads 9 are connected to the corrugated telescopic hose 10 through spray pipes 8, so that the spray heads 9 can be accurately aimed at the fabric in the spray tank 1. The vertically set U-shaped frames 5 allow the spray pipes 8 and spray heads 9 to rise and fall vertically under the drive of the guide frame 4, ensuring that the distance between the spray heads 9 and the fabric is appropriate. The connection between the spray heads 9 and the corrugated telescopic hose 10 through pipes ensures the smooth delivery of alkali solution, so that the alkali solution can be sprayed evenly onto the fabric, improving the uniformity and effectiveness of fabric treatment.

[0028] As an optional technical solution of this utility model, the top surface of the lifting frame 7 is fixedly connected to two symmetrically arranged guide rods 16, and two electric push rods 6 are located between the two guide rods 16. Both guide rods 16 are slidably connected to the U-shaped frame 5. The guide rods 16 on the top surface of the lifting frame 7, slidably connected to the U-shaped frame 5, can guide the lifting frame 7 when the electric push rods 6 drive it to rise and fall, ensuring the smooth up and down movement of the lifting frame 7 and preventing tilting or swaying. The guide rods 16, located between the two electric push rods 6, can work in conjunction with the electric push rods 6 to make the lifting process of the lifting frame 7 more stable, thereby ensuring the lifting accuracy of the spray pipe 8 and the spray head 9, enabling the spray head 9 to accurately reach the set spray height, and ensuring the accuracy and reliability of the alkaline solution spraying.

[0029] An alkaline spraying device for the production of self-cleaning, wash-free fabrics operates on the following principle:

[0030] 1): The hydraulic cylinder 3 drives the guide frame 4 to move up and down, realizing the overall height adjustment of multiple spray pipes 8. The electric push rod 6 on each U-shaped frame 5 can independently control the vertical position of the lifting frame 7 and the spray pipe 8, forming a dual adjustment mode of "overall + local".

[0031] 2): When processing thick canvas, the overall height of the guide frame 4 can be raised by the hydraulic cylinder 3, and the height of each spray pipe 8 can be finely adjusted by the electric push rod 6 to avoid friction between the spray head 9 and the fabric.

[0032] 3): When processing thin gauze, lower the guide frame 4 and adjust the height of the spray pipe 8 separately to ensure that the alkali solution is sprayed evenly at a suitable distance, which not only ensures the uniformity of spraying but also improves the utilization rate of alkali solution.

[0033] In summary, this alkaline spraying device for self-cleaning, wash-free fabric production utilizes a dual lifting structure of electric push rods and hydraulic cylinders to flexibly adjust the height and position of the spray pipes, solving the problem that traditional fixed guide pipes cannot adapt to different fabric thicknesses. Specifically, the hydraulic cylinder 3 drives the guide frame 4 to move up and down, achieving overall height adjustment of multiple spray pipes 8. Meanwhile, the electric push rod 6 on each U-shaped frame 5 can independently control the vertical position of the lifting frame 7 and the spray pipe 8, forming a dual adjustment mode of "overall + local". When processing thick canvas, the overall height of the guide frame 4 can be raised using the hydraulic cylinder 3, and the height of each spray pipe 8 can be finely adjusted using the electric push rod 6 to avoid friction between the spray head 9 and the fabric. When processing thin gauze, the guide frame 4 is lowered and the height of the spray pipe 8 is adjusted individually, allowing the alkaline solution to be sprayed evenly at a suitable distance. This ensures spray uniformity, improves alkaline solution utilization, and avoids splashing waste or fiber damage caused by improper height. The adjustable installation structure of the spray pipes, combined with the corrugated telescopic hose, enables flexible adjustment and reliable connection of the lateral position of the spray pipes. The threaded sleeve 11 slides on the U-shaped frame 5 through the slot 13, and with the locking bolt 12, it can fix the lateral position of the spray pipe 8 to meet the spraying requirements of fabrics of different widths. Meanwhile, the corrugated telescopic hose 10 connects the spray pipe 8 to the guide frame 4, and can freely extend and retract when the spray pipe 8 moves laterally or rises and falls, ensuring smooth delivery of the alkali solution while preventing the rigid pipe from breaking due to frequent movement. This design allows the spray pipe 8 to be precisely positioned according to the fabric width and spraying process requirements, solving the problem that traditional fixed guide pipes cannot adapt to different specifications of fabrics, and improving the versatility of the device and the flexibility of spraying operations.
