[0002] In the textile and printing and dyeing industry, it is usually necessary to clean the dyes from the fabrics. Some fabrics are decorative materials, including chemical fiber carpets, non-woven wall cloths, linen, nylon, colored tapes, flannel and other formats. Now, with the improvement of people's living standards, the decorative materials used have also changed from the initial wall painting to the current use of fabrics to decorate walls. Various fabrics play an important role. Fabrics are widely used in wall decoration, partitions and background decoration, forming a good commercial space display style; fabrics need to be dyed after they are produced. The general dyeing method is to immerse the fabric in liquid dyes, and then stir the liquid dyes and fabrics to color the fabrics. The colored fabrics need to be washed again to clean the floating colors on the surface before entering the next printing, stenting and other processes.

[0003] Traditional cloth washing operations usually use a water pump and multiple nozzles to spray water. Due to the limitation of water pump pressure, the water pressure is easily insufficient when washing thick cloth. At the same time, when using multiple nozzles for cleaning operations, there is also poor cleaning consistency and balance. Utility Model Content

[0004] The utility model aims to provide a wide-width pulse type printing and dyeing cloth washing machine, which uses a wide-width pulse method to wash cloth so as 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] A wide-width pulse-type printing and dyeing cloth washing machine comprises a washing box, a front guide roller and a rear guide roller, wherein clean water or washing liquid is placed in the washing box, the front guide roller and the rear guide roller are arranged in an inclined state, a flushing mechanism is arranged below the line connecting the front guide roller and the rear guide roller, the flushing mechanism comprises a cylinder body and a piston, the cylinder body is in the shape of an elongated strip, the piston is in the shape of a flat strip, and its four sides cooperate with the inner wall of the cylinder body, a first injection port and a second injection port are arranged at the upper ends of the front and rear sides of the cylinder body respectively, a one-way valve is arranged at the lower ends of the front and rear sides of the cylinder body, and a connecting rod and a power device are connected to the rear end of the piston.

[0007] Furthermore, the first jet port is at a high position, and the second jet port is at a low position, and the inclination angles of the two are consistent with the inclination angles of the front guide roller and the rear guide roller.

[0008] Furthermore, the injection gap of the first injection port is larger than the injection gap of the second injection port.

[0009] Furthermore, the distance between the first injection port and the second injection port and the reciprocating time of the piston match the conveying speed of the cloth.

[0010] Furthermore, the first jet opening and the second jet opening match the width of the cloth.

[0011] Furthermore, the outer wall of the piston is provided with a non-stick coating, and the inner wall of the cylinder body is provided with a wear-resistant coating.

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

[0013] Furthermore, a filter screen is arranged below the one-way valve.

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

[0015] Furthermore, a squeezing roller shaft is arranged at the rear end of the rear guide roller.

[0016] Compared with the existing technology, this solution has the following advantages:

[0017] The present invention is a wide-width pulse-type printing and dyeing cloth washing machine, which has a first jet port and a second jet port that match the width of the cloth, and directly sprays and washes the cloth, thereby achieving balanced washing of the cloth.

[0019] In order to ensure the continuous stability of cleaning, the reciprocating frequency of the piston is set and matched with the running distance of the cloth between the two nozzles. It can be achieved that during high-speed operation, the two nozzles can perform single-jet cleaning operations respectively, realizing double-jet cleaning, and avoiding the gap between the cloth in the previous nozzle, thereby improving the consistency of the jet cleaning.

[0025] refer to Figures 1 to 3 A wide-width pulse-type printing and dyeing cloth washing machine comprises a washing box 1, a front guide roller 11 and a rear guide roller 12. Clean water, a washing liquid or a special solvent (hereinafter referred to as water) is placed in the washing box 1 for washing cloth. The cloth to be washed is flatly fed 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 thereof can be about 30 degrees. The cloth is transported linearly between the front guide roller 11 and the rear guide roller 11.

[0026] A flushing mechanism 2 is arranged below the front guide roller 11 and the rear guide roller 12 for conveying the fabric. The flushing mechanism 2 includes a cylinder body 21 and a piston 22. The cylinder body 21 is a horizontally arranged long strip box-type structure. The length of the cylinder body also matches the width of the fabric. The piston 22 is a flat strip, and its four sides cooperate 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 arranged 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 to penetrate the rear chamber and the front chamber of the cylinder body 22. To be precise, the first injection port 31 and the second injection port 31 are both long strip slit structures, and a corresponding long groove is also opened on the cylinder body 22, which can make the water inside the chamber be transported to the corresponding injection port in a straight line and uniformly.

[0027] In order to achieve precise spray cleaning operation on the cloth, the first jet port 31 is in a high position and the second jet port 32 is in a low position, and the inclination angles of the two are consistent with the inclination angles of the front guide roller 11 and the rear guide roller 12.

[0028] In some embodiments, the distances between the first jet port 31 and the second jet port 32 and the cloth are equidistant, so as to achieve equal jet cleaning operations for both.

[0029] In some embodiments, the distance between the first jet port 31 and the cloth is slightly greater than the distance between the second jet port 32 and the cloth, so the jetting operation of the first jet port 31 is relatively divergent, while the second jet port 32 is relatively convergent, thereby achieving differential cleaning operations.

[0030] In some embodiments, the spray gap of the first spray port 31 is larger than the spray gap of the second spray port 32 , so the spray operation of the first spray port 31 is relatively divergent, while the second spray port 32 is relatively convergent, thereby achieving differential cleaning operations.

[0031] A one-way valve 23 is arranged at the lower end of both the front and rear sides of the cylinder body 21. The one-way valve 23 is a cylindrical one-way valve. Specifically, a straight groove is arranged at the lower end of both the front and rear sides of the cylinder body 21. A straight metal cylinder is arranged on the straight groove. The straight groove has a funnel-shaped structure. When the metal cylinder fits with the straight groove, the arc-shaped inner wall of the straight groove is just in close contact with the metal cylinder, and the corresponding chamber;

[0032] The rear end of the piston 22 is connected to a connecting rod 25, which is sealed with the cylinder body 21 and the cleaning box through a sealed bearing. A rocker 26 is rotatably provided at the rear end of the connecting rod, and the rocker 26 is rotatably connected to a flywheel 27. The flywheel 27 is connected to a motor 28 through a reduction belt. The connecting rod 25, the rocker 26, and the flywheel 27 are two symmetrical groups of structures, which can achieve smooth displacement 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.

[0033] refer to Figure 4 Figure 5 In actual operation, the piston 22 is pushed or pulled by the motor 28 and the connecting rod 25 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 the one-way valve. At the front chamber, the one-way valve is in a closed state, so the water in the front chamber is forced to be ejected outward from the second injection port 32 at a high speed, and the spray cleaning operation of the cloth is implemented; conversely, when the piston 22 moves backward, the water in the rear chamber is forced to be ejected outward from the first injection port 31 at a high speed, and the spray cleaning operation of the cloth is also implemented, thereby realizing a continuous and stable cloth cleaning operation.

[0034] In actual operation, the distance between the first jet port and the second jet port and the time for the piston to reciprocate match the conveying speed of the cloth, that is, the time used for a single stroke of the piston 22 is slightly less than the time for the cloth to be conveyed between the first jet port 31 and the second jet port 32. Therefore, during the intermittent jet cleaning operation, the cloth is always under continuous cleaning.

[0035] In order to improve the durability of the piston 22 and the cylinder body 21, the outer wall of the piston 22 is provided with a non-stick coating, which may be a Teflon non-stick coating, and the inner wall of the cylinder body 21 is provided with a wear-resistant coating, which may be a ceramic crystal coating.

[0036] In some embodiments, a filter screen 30 is arranged below the one-way valve 23. The filter screen 30 can be a fine metal screen for filtering tiny limits or foreign objects in the water. In order to increase the water content of the cloth after washing, an extrusion roller 13 is arranged at the rear end of the rear guide roller. The extrusion roller 13 squeezes the cloth through a pair of rollers to squeeze out the water in the cloth and allow the water to flow back into the washing box 1.

[0037] In summary, the wide-width pulse printing and dyeing cloth washing machine of the present invention directly sprays and washes the cloth by having a first jet port and a second jet port that match the width of the cloth, thereby achieving balanced cleaning of the cloth. Since the first jet port and the second jet port are connected to the front and rear of the cylinder body, the cleaning operation can be performed intermittently, and the continuous and stable cleaning operation can be ensured.

[0038] This scheme adopts a front and rear spray cylinder and piston structure, that is, when the piston moves forward, the rear chamber is filled with water and the front chamber is drained and sprayed, and when the piston moves backward, the front chamber is filled with water and the rear chamber is drained and sprayed, forming a continuous water spraying operation, which has the characteristics of high efficiency, good stability and complete cleaning operation;

[0039] In order to ensure the continuous stability of cleaning, the reciprocating frequency of the piston is set and matched with the running distance of the cloth between the two nozzles. It can be achieved that during high-speed operation, the two nozzles can perform single-jet cleaning operations respectively, realizing double-jet cleaning, and avoiding the gap between the cloth in the previous nozzle, thereby improving the consistency of the jet cleaning.
