technical field

The utility model relates to the field of textile printing, in particular to a nozzle for imaging on textiles and a printing machine equipped with the nozzle.

Background technique

Existing printing and imaging of textiles, such as the printing and imaging of carpets or blankets, mainly uses the nozzle of the printing machine to spray a developer such as dye on the textile to realize the printing and imaging of images or characters. The printing machine includes a body on which a head car, an air circuit assembly providing positive pressure, and a circuit board for controlling the printing process are arranged. A dye tank containing dye is installed on the head car. Multiple sprinklers. The existing spray head includes a valve body. A hollow cavity is formed in the valve body along the axial direction. A coil is arranged in the hollow cavity. A feeding pipe and a nozzle are respectively installed at both ends of the cavity. The feeding pipe is located inside the coil. A pipeline for conveying dye is arranged between the feed pipe and the nozzle, and a valve core is provided at the position between the cavity and the nozzle, and the valve core is used to conduct or block the pipe for conveying dye. road. The valve core is in elastic contact with the valve body through the shrapnel, and a plurality of diversion holes for conveying the dye are arranged on the shrapnel.

When the printing machine is working, the circuit board controls the coil to conduct current, so that the feeding tube in the coil generates magnetism, and then the valve core is moved to the position where the pipeline is conducting through the magnetism, and the dye passes through the feeding tube and the guide tube in turn. The orifice is output to the outlet of the nozzle, and finally the image is printed on the textile.

However, nowadays, the printing and imaging speed requirements for textiles are getting higher and higher. At the same time, due to the thicker textiles such as carpets or blankets, the nozzle needs a larger spraying volume to meet the requirements of fast printing imaging and forming on thicker textiles. Good printing quality, because the above-mentioned existing nozzles adopt shrapnel type reset, and by opening diversion holes on the shrapnel, if a larger diversion hole is opened, it will affect the overall structure of the shrapnel and then affect its elastic recovery force. Opening smaller diversion holes can no longer meet the needs of large circulation. At the same time, the existing nozzles cannot be disassembled after the production is completed, that is, the shrapnel, seals or other parts cannot be replaced, so that when the nozzle fails, the entire nozzle needs to be replaced, which increases the maintenance cost of the printing machine, which is not conducive to cost reduction and promotion. use.

Contents of the invention

The first purpose of the utility model is to provide a spray head with a larger spraying volume.

The second purpose of the utility model is to provide a printing machine with a relatively large amount of spraying.

In order to achieve the first purpose of the utility model, the utility model provides a nozzle, including a valve body, a feed pipe, a nozzle, a valve core and a spring. A hollow cavity is formed in the valve body along the axial direction, and the two ends of the cavity A first opening and a second opening are formed, the feed pipe is installed on the first opening, the nozzle is installed on the second opening, the nozzle is provided with a discharge port, and the coil is arranged in the cavity, wherein the valve core passes through the coil and can be Sliding along the axial direction, a pipeline for conveying dye is formed between the spool and the coil, and a valve part for blocking the discharge port is arranged on the end of the spool facing the nozzle, the spring is sleeved outside the spool, and the second part of the spring One end abuts against the valve body, and the second end of the spring abuts against the valve part.

The dyestuff can be smoothly delivered to the nozzle without any restriction, thereby increasing the spraying quantity of the nozzle. At the same time, the spring has a better elastic recovery force, so that the valve part can be more closely contacted with the outlet of the nozzle, thereby improving its sealing performance, effectively avoiding the leakage of dye from the nozzle, and effectively improving the durability of the nozzle. Most of the existing nozzles use feeding pipes for magnetization. Since the pipes for conveying dyes are arranged in the feeding pipes, the magnetic permeability of the feeding pipes is limited, which means that the magnetic force generated by the feeding pipes is relatively small. However, the utility model uses The valve core is magnetized, and pipelines are arranged on both sides of the valve core, so that the magnetic permeability of the valve core is relatively large, and the magnetic force of the valve core is effectively improved, thereby further improving the control performance of the nozzle.

A more advanced solution is that the feed pipe passes through the coil, and the end of the feed pipe facing the valve core is provided with a positioning part for adjoining the valve core.

It can be seen from the above that since the spool is set in the coil, the spool will be magnetic when the coil conducts electricity, and the feeding tube is also set in the coil, and the feeding tube will also generate magnetism when the coil is conducting, which in turn makes the valve When the core and the feed pipe are magnetic, they attract each other and move the valve core to the position where the pipeline is in a state of conduction, that is, the position where the positioning part is adjacent to the feed pipe, which is beneficial to improve the control performance of the nozzle.

A more advanced solution is that the feed pipe is provided with a guide hole communicating with the pipeline radially through the positioning portion.

It can be seen from the above that while the feed pipe is adjacent to the valve core, it passes through the guide holes set radially through, so that the delivery of the dye is not affected by the mutual adjacency, which is beneficial to increase the spraying amount.

A more advanced solution is that the nozzle is threadedly engaged with the inner wall of the second opening.

It can be seen from the above that the nozzle can be disassembled from the second opening through the threaded nozzle and the second opening, and then the wearing parts in the cavity such as the spring and the valve core can be replaced. The body makes it easier and more convenient to disassemble or install the spring and valve core, effectively reduces maintenance costs, and is also conducive to popularization and use.

A more advanced solution is that at least two operating holes are provided on the outer wall of the nozzle.

It can be seen from the above that the nozzle is disassembled through at least two operation holes provided on the outer wall of the nozzle, so that there is no need to set a hexagonal hole as an operation hole at the discharge port. Since the processing of the operation holes such as hexagonal holes is relatively complicated, it is convenient for users to disassemble. At the same time, the processing procedure is also simplified.

In order to achieve the second purpose of the utility model, the utility model provides a printing machine, including a machine body, a dye tank installed on the machine body and at least one spray head arranged below the dye tank, the spray head includes a valve body, a feed pipe, a nozzle , valve core and spring, a hollow cavity is formed in the valve body along the axial direction, a first opening and a second opening are formed at both ends of the cavity, the feed pipe is installed on the first opening, and the nozzle is installed on the second opening , the nozzle is provided with a discharge port, the coil is set in the cavity, wherein the valve core passes through the coil and can slide axially, a pipeline for conveying dye is formed between the valve core and the coil, and the valve core faces the end of the nozzle A valve part for blocking the discharge port is arranged on the top, the spring is sleeved outside the valve core, the first end of the spring abuts against the valve body, and the second end of the spring abuts against the valve part.

It can be seen from the above scheme that since the spring is coiled and bent by strip metal, the spring is used for the reset of the valve core, so that the spring set in the pipeline will not affect the delivery of the dye, and then the dye in the pipeline will not be affected. The dyestuff can be smoothly delivered to the nozzle without any restriction, thereby increasing the spraying quantity of the nozzle. At the same time, the spring has better elastic recovery force, so that the valve part can be more tightly contacted with the outlet of the nozzle, thereby improving its sealing performance, effectively preventing the nozzle from leaking dye, and effectively improving the durability of the nozzle. Most of the existing nozzles use feeding pipes for magnetization. Since the pipes for conveying dyes are arranged in the feeding pipes, the magnetic permeability of the feeding pipes is limited, which means that the magnetic force generated by the feeding pipes is relatively small. However, the utility model uses The valve core is magnetized, and pipelines are arranged on both sides of the valve core, so that the magnetic permeability of the valve core is relatively large, and the magnetic force of the valve core is effectively improved, thereby further improving the control performance of the printing machine on the nozzle.

The coil 23 is annularly disposed in the cavity, and the sealing member 24 is also annularly disposed in the cavity. The outer wall of the sealing member 24 is adjacent to the inner wall of the cavity, and then the sealing member 24 fixes the coil 23 in the cavity. The feeding pipe 22 is arranged in the coil 23 after passing through the first opening and the sealing member 24. A pipeline 221 for communicating with the dye tank 1 is formed in the feeding pipe 22 along the axial direction.

The electrical contacts under the tank 1 are electrically connected, and then receive working current.

The spool 25 is a cylindrical body extending in the axial direction, and the spool 25 is set in the cavity and at a position passing through the coil 23 , that is, at a position in the sealing member 24 . A pipeline 26 for conveying dye is formed between the valve core 25 and the sealing member 24 , and the pipeline 26 communicates with the guide hole 223 and the pipeline 221 . A valve portion 251 is disposed on the end of the valve core 25 facing the nozzle 28 , a sealing member 252 is disposed on the valve portion 251 , and a first flange is formed on an outer wall of the valve portion 251 .

The spring 27 is set in the cavity and sleeved outside the valve core 25. The first end of the spring 27 abuts against the first convex edge of the valve part 251, and the second end of the spring abuts against the second convex edge provided on the inner wall of the valve body 21. .

It can be smoothly delivered to the nozzle without any restriction, thereby increasing the spraying amount of the nozzle. At the same time, the spring has better elastic recovery force, so that the valve part can be more tightly contacted with the outlet of the nozzle, thereby improving its sealing performance, effectively preventing the nozzle from leaking dye, and effectively improving the durability of the nozzle.
