Description

Technical Field

[0001] The utility model relates to the technical field of printing and dyeing cloth washing, in particular to a reciprocating pulse flushing mechanism of a cloth washing machine. Background Art

[0002] In the textile and printing and dyeing industries, it is usually necessary to clean the dyes on the cloth. Some cloths are a kind of decorative materials, including various cloths such as chemical fiber carpets, non-woven wall cloths, linen cloths, nylon cloths, colored adhesive tapes, and flannel. Now, with the improvement of people's living standards, the decorative materials used have changed from the initial wall painting to the current use of cloth to decorate the walls, and various cloths play an important role. Cloths are widely used in wall surface decoration, partitions, and background decoration, forming a good commercial space display style; after the cloth is produced, it needs to be dyed. The general dyeing method is to immerse the cloth in liquid dye, and then stir the liquid dye and the cloth to make the cloth colored. The colored cloth also needs to be washed once to wash the floating color on its surface clean before entering the next processes such as printing and stentering.

[0003] For traditional cloth washing operations, it is usually carried out by means of a water pump and spraying water through multiple nozzles. Due to being restricted by the water pump pressure, when dealing with thick cloths, the water pressure is prone to be insufficient. At the same time, when using multiple-point nozzles for cleaning operations, there are also problems of poor cleaning consistency and balance. Content of the Utility Model

[0004] The purpose of the utility model is to provide a reciprocating pulse flushing mechanism of a cloth washing machine, which uses a wide-width pulse method to wash the cloth to improve the efficiency and balance of cloth washing.

[0005] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0006] The reciprocating pulse flushing mechanism of a cloth washing machine includes a cylinder body and a piston. The cylinder body is strip-shaped, the piston is flat-strip-shaped, and its periphery is matched with the inner wall of the cylinder body. The upper ends of the front and rear sides of the cylinder body are respectively provided with a first injection port and a second injection port. Check valves are arranged at the lower ends of the front and rear sides of the cylinder body. A rocker is arranged at the rear end of the connecting rod, the rocker is connected with a flywheel, and the flywheel is connected with a motor through a reduction belt.

[0007] Further, the first injection port is in a high position, the second injection port is in a low position, and their inclination angles are the same as the inclination angles of the front guide roller and the rear guide roller.

[0008] Further, the injection gap of the first injection port is greater than the injection gap of the second injection port.

[0009] Further, the distance between the first injection port and the second injection port and the time for the piston to reciprocate are matched with the conveying speed of the fabric.

[0010] Further, the first injection port and the second injection port are matched with the width of the fabric.

[0011] Further, a non-stick coating is provided on the outer wall of the piston, and a wear-resistant coating is provided on the inner wall of the cylinder block.

[0012] Further, the one-way valve is a cylindrical one-way valve.

[0013] Further, a filter screen is arranged around the lower part of the one-way valve.

[0014] Further, a rocker is arranged at the rear end of the connecting rod. The rocker is connected with a flywheel, and the flywheel is connected with the motor through a reduction belt.

[0015] Adopting this solution, compared with the prior art, it has the following advantages:

[0016] The reciprocating pulse flushing mechanism of the fabric washing machine in this solution directly sprays and cleans the fabric through the first injection port and the second injection port that are matched with the width of the fabric, realizing the balanced cleaning of the fabric. Since the first injection port and the second injection port are connected to the front and rear of the cylinder block, the cleaning operation can be carried out intermittently, and the continuity and stability of the cleaning operation can be ensured.

[0017] This solution adopts a front and rear jet cylinder block and piston structure, that is, when the piston moves forward, water enters the rear chamber and the front chamber drains and sprays, and when the piston moves backward, water enters the front chamber and the rear chamber drains and sprays, forming a continuous water spraying operation, which has the characteristics of high efficiency, good stability and complete cleaning operation.

[0018] In order to ensure the continuous stability of cleaning, by setting the reciprocating frequency of the piston and making it match the running distance of the fabric between the two injection ports, it can be realized that when running at high speed, the two injection ports respectively perform single-shot spraying and cleaning operations, realizing double-shot spraying and cleaning, and the gap of the fabric at the previous injection port can be avoided, improving the consistency of spraying and cleaning.

[0024] Reference Figures 1 to 3 , a wide-width pulse-type fabric dyeing and washing machine, including a cleaning tank 1, a front guide roller 11 and a rear guide roller 12. Clear water, cleaning liquid or special solvent (hereinafter referred to as water) is placed in the cleaning tank 1 for cleaning fabrics. The fabric to be cleaned is flatly input from one end of the front guide roller 11. The front guide roller 11 and the rear guide roller 12 are arranged in an inclined state, and the inclination angle can be about 30 degrees generally. The fabric is linearly conveyed between the front guide roller 11 and the rear guide roller 11.

[0025] A flushing mechanism 2 is arranged below the fabric conveyance of the front guide roller 11 and the rear guide roller 12. The flushing mechanism 2 includes a cylinder body 21 and a piston 22. The cylinder body 21 is a horizontally arranged long strip-shaped box structure, and the length of the cylinder body also matches the width of the fabric. The piston 22 is a flat strip-shaped, and its periphery cooperates with the inner wall of the cylinder body 21. The upper ends of the front and rear sides of the cylinder body 22 are respectively provided with a first injection port 31 and a second injection port 32. The first injection port 31 and the second injection port 32 are respectively arranged through the rear chamber and the front chamber of the cylinder body 22. Exactly speaking, both the first injection port 31 and the second injection port 31 are long strip-shaped slit structures, and long grooves are correspondingly opened on the cylinder body 22, so that the water inside the chamber can be linearly and evenly conveyed to the corresponding injection port.

[0026] In order to achieve precise jet cleaning operation on the fabric, the first injection port 31 is in a high position, and the second injection port 32 is in a low position. The inclination angles of both are the same as the inclination angles of the front guide roller 11 and the rear guide roller 12.

[0027] In some embodiments, the distances between the first injection port 31 and the second injection port 32 and the fabric are in an equidistant state to achieve equivalent jet cleaning operations for both.

[0028] In some embodiments, the distance between the first injection port 31 and the fabric is slightly greater than the distance between the second injection port 32 and the fabric. Therefore, the jet operation of the first injection port 31 is relatively divergent, while the second injection port 32 is relatively convergent, thereby achieving different cleaning operations.

[0029] In some embodiments, the injection gap of the first injection port 31 is greater than the injection gap of the second injection port 32. Therefore, the jet operation of the first injection port 31 is relatively divergent, while the second injection port 32 is relatively convergent, thereby achieving different cleaning operations.

[0030] One-way valves 23 are arranged at the lower ends of the front and rear sides of the cylinder block 21. The one-way valves 23 are cylindrical one-way valves. Specifically, straight grooves are provided below the front and rear sides of the cylinder block 21, and linear metal cylinders are arranged on the straight grooves. The straight grooves are in a funnel-shaped structure. When the metal cylinders are in contact with the straight grooves, the arc-shaped inner walls of the straight grooves are just in close contact with the metal cylinders, and when corresponding chambers;

[0031] The rear end of the piston 22 is connected to a connecting rod 25. The connecting rod 25 is sealed with the cylinder block 21 and the cleaning tank through a sealing bearing. A rocker 26 is rotated at the rear end of the connecting rod. The rocker 26 is rotatably connected to a flywheel 27. The flywheel 27 is connected to a motor 28 through a reduction belt. And the connecting rod 25, the rocker 26, and the flywheel 27 are of two symmetrical sets of structures, which can realize the smooth pushing of the piston 22. And the flywheel 27 plays an inertial rotation role, which can improve the stability of the reciprocating motion of the piston 22 and reduce the impact on the motor 28.

[0032] Reference Figure 4 Figure 5 , during actual operation, the motor 28 and the connecting rod 25 are used to push or pull the piston 22 to perform horizontal reciprocating motion. When the piston 22 moves forward, the water in the front chamber is compressed, and the one-way valve 23 at the rear chamber is in an open state. The water in the rear chamber enters the rear chamber from this one-way valve. At the front chamber, the one-way valve is in a closed state. Therefore, the water in the front chamber is forced to be ejected outward at a high speed from the second ejection port 32, and the spraying and cleaning operation of the fabric is carried out; conversely, when the piston 22 moves backward, the water in the rear chamber is forced to be ejected outward at a high speed from the first ejection port 31, and the spraying and cleaning operation of the fabric is also carried out, so as to realize continuous and stable fabric cleaning operation.

[0033] During actual operation, the distance between the first ejection port and the second ejection port and the reciprocating time of the piston are matched with the conveying speed of the fabric, that is, the time taken for a single stroke of the piston 22 is slightly less than the time for the fabric to be conveyed and travel between the first ejection port 31 and the second ejection port 32. Therefore, during the intermittent spraying and cleaning operation, the fabric is always under continuous cleaning.

[0034] In order to improve the durability of the piston 22 and the cylinder block 21, a non-stick coating is provided on the outer wall of the piston 22. This coating can be a Teflon non-stick coating. A wear-resistant coating is provided on the inner wall of the cylinder block 21. This coating can be a ceramic crystal coating.

[0035] In some embodiments, a filter screen 30 is arranged around the lower part of the one-way valve 23. The filter screen 30 can be a fine metal mesh, which is used to filter fine limits or foreign objects in the water; in order to increase the water content of the fabric after cleaning, a squeezing roller shaft 13 is arranged at the rear end of the rear guide roller. The squeezing roller shaft 13 squeezes the fabric through a pair of roller shafts, which is used to squeeze out the water in the fabric and make the water flow back into the cleaning tank 1.

[0036] In summary, a wide-width pulse type fabric printing and washing machine in this solution directly sprays and cleans the fabric through the first spray port and the second spray port that match the width of the fabric, achieving balanced cleaning of the fabric. Since the first spray port and the second spray port are connected to the front and back of the cylinder body, intermittent cleaning operations can be carried out, and continuous and stable cleaning operations are ensured.

[0037] This solution adopts a front and rear jet cylinder and piston structure. That is, when the piston moves forward, water enters the rear chamber and the front chamber drains and sprays. When the piston moves backward, water enters the front chamber and the rear chamber drains and sprays, forming a continuous water spraying operation, which has the characteristics of high efficiency, good stability and complete cleaning operation.

[0038] To ensure the continuous stability of cleaning, by setting the reciprocating frequency of the piston and making it match the running distance of the fabric between the two spray ports, it can be realized that when running at high speed, the two spray ports respectively perform single-shot spraying and cleaning operations, achieving double spraying and cleaning, and can avoid the gap of the fabric at the previous spray port, improving the consistency of spray cleaning.
