Description

Technical Field

[0001] This application belongs to the field of textile machinery technology, and in particular relates to a water washing device for the guide belt of a printing machine and its control method. Background Technology

[0002] Rotary screen printing machines are a major type of equipment for textile printing. They work by having a rotary screen roll along a guide belt, causing the printing paste to be applied to the fabric via a squeegee or magnetic rod device, forming specific patterns and colors, thus completing the printing process. During the printing process, the outer surface of the guide belt accumulates various contaminants such as lint, loose threads, and printing paste.

[0003] A Chinese patent with publication number CN104842646B discloses a water washing and cleaning device for the guide belt of a rotary screen printing machine, including a guide belt, a brush roller, and a water tank. Multiple brushes are fixed on the outer circumference of the brush roller, and a brush clip layer is fitted onto the brush roller. The brush clip layer includes a main body and multiple cylindrical sleeves protruding outward from the main body. The cylindrical sleeves tightly wrap around the corresponding brushes, and the height of the cylindrical sleeves is less than the height of the corresponding brushes. Elastic, soft brush cleaning needles are provided on the inner wall of the water tank near the brush roller. Each brush cleaning needle includes a base and multiple evenly distributed cleaning needles fixed on the base. Parts of the brush cleaning needles extend outward from the side of the support base and contact one end of the brush. A water inlet is provided on one side wall of the water tank, communicating with a water tank containing a water pump. A sewage drain outlet is provided on the wall of the water tank below the support base.

[0004] Although the brush in the above-mentioned cleaning device can remove impurities such as lint and thread from the guide belt, the amount of water that the brush can move during rotation is limited, and the small amount of water applied to the guide belt is insufficient to clean the slurry. Summary of the Invention

[0005] The purpose of this application is to address the aforementioned technical problems by providing a water washing device for the guide belt of a printing machine, which effectively improves the cleaning of the paste on the guide belt.

[0006] This application provides a washing device for a printing machine guide belt, including a guide belt, a water tank, a brush roller, and cleaning needles, and further comprising:

[0007] A brush assembly is placed on a brush roller, the brush assembly including a brush body and a first connector;

[0008] The mounting shaft is movably connected to the brush roller;

[0009] The second connector is placed on the mounting shaft and corresponds to the first connector;

[0010] A connecting mechanism is positioned between the second connector and the first connector;

[0011] The mounting shaft is provided with a first conveying cavity, a first conveying port and a second conveying port connected to the first conveying cavity. The first conveying port is closer to the water tank, and the second conveying port is farther from the water tank. The mounting shaft is provided with a first conveying pipe placed in the first conveying cavity. The first conveying pipe is provided with a first spray nozzle corresponding to the second conveying port. The brush body is provided with a hollow channel. The first connector and the brush roller are connected by a ball joint, and the second connector and the mounting shaft are connected by a ball joint.

[0012] Several brush assemblies are installed on the brush roller. The brush assemblies rotate with the brush roller. The mounting shaft is movably connected to the brush roller. When the brush roller rotates, after the two sets of brush assemblies are connected to the first conveying port and the second conveying port respectively through the connecting mechanism, they are connected to the air compressor pump through the first conveying pipe. The first jet port sprays out a high-speed airflow, which is then sprayed out through the second conveying port. At the same time, it rolls the air in the first conveying chamber to flow to the second conveying port. The first conveying port is connected to the first conveying chamber and connects to the hollow channel of the corresponding brush body. Water in the water tank is drawn through the hollow channel and then sprayed out through the first conveying port, the first conveying chamber, the second conveying port, and the hollow channel of the brush body corresponding to the second conveying port. This ensures that the brush body has sufficient water to wet and clean it when it acts on the guide belt.

[0013] Existing water is sprayed through nozzles located on one side of the brush roller. However, when the high-pressure spray from the nozzles acts on the guide belt at a distance from the brush, the water and brush body cannot act on the guide belt simultaneously, resulting in poor cleaning effect on the slurry. On the other hand, when the high-pressure spray from the nozzles is close to the brush, the high-pressure water flow impacts the brush body, affecting its cleaning effect on other impurities. By drawing water from the water tank and mixing it with air through the brush body corresponding to the first conveying port, the cleaning effect of the brush body on the slurry can be further improved.

[0014] Furthermore, the connecting mechanism includes:

[0015] The sleeve is placed on the second connector.

[0016] A telescopic tube is inserted into the sleeve, and the telescopic tube is provided with a connecting groove;

[0017] The first magnet is placed in the connecting slot;

[0018] The second magnet is placed on the first connector and corresponds to the first magnet;

[0019] A sealing ring is placed in the connecting groove and is adapted to the first connector.

[0020] A reset component is used to reset the connecting mechanism;

[0021] The valve assembly is located between the sleeve and the telescopic tube;

[0022] The sleeve is provided with a first limiting part, and the telescopic tube is provided with a second limiting part, wherein the first limiting part and the second limiting part are adapted to each other.

[0023] The sleeve and telescopic tube are installed on the mounting shaft. During the rotation of the brush assembly, the telescopic tube is connected to the corresponding first connector by the mutual attraction between the first magnet and the second magnet. The sealing ring improves the sealing of the connection position. When the first magnet and the second magnet cooperate with each other, the valve assembly is opened, which facilitates the communication between the first connector and the second connector. As the brush roller rotates, the telescopic tube extends out of the sleeve. When the first limit part and the second limit part interact with each other, the first connector and the second connector are reset by the reset assembly, and the valve assembly is closed.

[0024] Furthermore, the reset component includes:

[0025] The mounting plate is placed on the sleeve;

[0026] The first return spring is placed between the mounting plate and the mounting shaft.

[0027] The second return spring is placed between the mounting plate and the telescopic tube;

[0028] The third reset spring is placed between the first connector and the brush roller.

[0029] The mounting plate and the sleeve are connected as a whole. The first return spring resets the sleeve and the mounting shaft to facilitate subsequent connection. The second return spring resets the sleeve and the telescopic tube. The third return spring resets the first connector.

[0030] There are three or more first and second reset springs, which are evenly distributed around the axis of the sleeve. There are three or more third reset springs, which are evenly distributed around the axis of the first connector.

[0031] Furthermore, the valve assembly includes:

[0032] A valve seat is placed inside the sleeve, and the valve seat is provided with a vent hole;

[0033] The valve body is placed on the valve seat;

[0034] The valve port is placed on the telescopic tube and is adapted to the valve body.

[0035] Under normal conditions, the telescopic tube is retracted into the sleeve by the second return spring, so that the valve port and the valve body cooperate, and the second connector is in a closed state. The valve body is installed on the valve seat, and the vent is connected to the first delivery chamber. When the first connector and the second connector are connected by the connecting mechanism, the valve body and the valve port are opened, so that the first connector and the second connector are connected.

[0036] Furthermore, the mounting shaft is provided with a guide seat, and the side wall of the guide seat is provided with a guide wall adapted to the first connector.

[0037] The guide seat is mounted on the mounting shaft and connected by bolts or screws or by welding. When the brush assembly rotates past the position of the guide seat, the first connector abuts against the guide wall. With the movement of the brush assembly and the action of the reset assembly, the brush head can have a travel along the axial direction of the mounting shaft, so that the brush assembly can swing and improve the cleaning effect of the brush body on the guide belt.

[0038] Furthermore, the mounting shaft is provided with a protruding seat, the protruding seat corresponding to the position of the cleaning needle, the protruding seat is provided with a sliding groove, the first connector is provided with a sliding part adapted to the sliding groove, a guide opening is provided on one side of the protruding seat, the first connector is provided with a spraying mechanism, the protruding seat is provided with a plurality of connecting holes evenly arranged in the sliding groove, the connecting holes are connected to the first conveying pipe, the connecting holes are provided with a switch seat, and the switch seat is provided with a fourth return spring.

[0039] During the rotation of the brush assembly, the sliding part of the first connector is guided into the slide groove through the guide opening. The sliding part abuts and matches the slide groove, and the sliding part abuts against the switch seat. Each connection hole corresponds to a switch seat. When the first connector moves along the slide groove, the air in the first delivery pipe is ejected through the connection hole by the ejection mechanism, so that the gas acts on the brush body, accelerating the separation of impurities on the brush body from the brush body. When the sliding part moves, the corresponding connection hole opens. After the movement is completed, the connection hole is reset and closed by the fourth reset spring.

[0040] Furthermore, the ejection mechanism includes:

[0041] A movable seat is placed on the first connector head, and the side wall of the movable seat is provided with a through hole;

[0042] The plug is placed on the first connector and is adapted to the movable seat;

[0043] The fifth return spring is located between the movable seat and the first connector.

[0044] The first connector is provided with a spray hole, which corresponds to the through hole.

[0045] When the sliding part abuts against the groove, the movable seat retracts into the first connector, causing the movable seat to abut against the plug, closing the connection between the movable seat and the hollow channel of the brush body, and connecting the through hole with the nozzle, so that the gas flowing out of the connecting hole is ejected through the nozzle and acts on the brush body.

[0046] The second magnet is mounted on the movable base.

[0047] This application also provides a control method for a water washing device on a printing machine guide belt, the specific steps of which include:

[0048] S1, the brush roller drives the brush assembly to rotate. When the first connector and the second connector on the brush roller are engaged, high-pressure gas is blown out through the first conveying pipe, water is drawn from the water tank through the brush body on the side corresponding to the first conveying port, and sprayed out through the brush body on the side corresponding to the second conveying port, sprayed onto the guide belt, to wet the slurry and then clean it.

[0049] S2, through the protruding seat corresponding to the brush body, sprays gas, which, together with the action of the cleaning needle, efficiently separates lint and thread ends from the brush body.

[0050] At the point where the brush body contacts the guide belt, a mixture of water and air is sprayed from the brush body, which acts on the slurry on the guide belt to improve the cleaning effect on the slurry. At the point where the brush body interacts with the cleaning needle, air is sprayed from the first connector to act on the brush body, which accelerates the separation of impurities such as lint and lint from the brush body.

[0051] The beneficial effects of this application are:

[0052] 1. When the brush roller rotates, after the two sets of brush assemblies are connected to the first conveying port and the second conveying port respectively through the connecting mechanism, the water in the water tank is drawn through the hollow channel and then sprayed out through the first conveying port, the first conveying chamber, the second conveying port, and the hollow channel of the brush body corresponding to the second conveying port. This ensures that the brush body has sufficient water to wet and clean it when it acts on the guide belt, without interfering with the brush body's cleaning of lint and thread ends.

[0053] 2. The telescopic tube is connected to the corresponding first connector by the mutual attraction between the first magnet and the second magnet. The sealing ring improves the sealing of the connection position. When the first magnet and the second magnet cooperate with each other, the valve assembly is opened, so that the first connector and the second connector are connected to each other.

[0054] 3. As the brush assembly moves and the reset assembly functions, the brush head can move along the axis of the mounting shaft, causing the brush assembly to oscillate during movement, thus improving the cleaning effect of the brush body on the guide belt.

[0055] 4. As the first connector moves along the slide, the air in the first conveying pipe is ejected through the connecting hole via the ejection mechanism, so that the gas acts on the brush body, accelerating the separation of impurities from the brush body. Attached Figure Description

[0064] The portable server provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0065] Example 1:

[0066] like Figure 1 , Figure 2 As shown, this application embodiment provides a washing device for a printing machine guide belt 100, including a guide belt 100, a water tank 110, a brush roller 120, and a cleaning needle 130, and further includes:

[0067] A brush assembly 200 is placed on a brush roller 120. The brush assembly 200 includes a brush body 210 and a first connector 220.

[0068] The mounting shaft 300 is movably connected to the brush roller 120;

[0069] The second connector 400 is placed on the mounting shaft 300 and corresponds to the first connector 220;

[0070] The connecting mechanism 500 is positioned between the second connector 400 and the first connector 220;

[0071] The mounting shaft 300 is provided with a first conveying cavity 310, and a first conveying port 320 and a second conveying port 330 connected to the first conveying cavity 310. The first conveying port 320 is closer to the water tank 110, and the second conveying port 330 is farther away from the water tank 110. The mounting shaft 300 is provided with a first conveying pipe 600 placed in the first conveying cavity 310. The first conveying pipe 600 is provided with a first spray port 610 corresponding to the second conveying port 330. The brush body 210 is provided with a hollow channel 211. The first connector 220 is connected to the brush roller 120 through a ball joint, and the second connector 400 is connected to the mounting shaft 300 through a ball joint.

[0072] Several brush assemblies 200 are mounted on the brush roller 120. The brush assemblies 200 rotate with the brush roller 120. The mounting shaft 300 is movably connected to the brush roller 120. When the brush roller 120 rotates, after two sets of brush assemblies 200 are respectively connected to the first conveying port 320 and the second conveying port 330 through the connecting mechanism 500, an air compressor pump is connected through the first conveying pipe 600. A high-speed airflow is ejected from the first jet port 610 and ejected through the second conveying port 330, while simultaneously rotating the first conveying chamber 31. Air in 0 flows to the second conveying port 330. The first conveying port 320 is connected to the first conveying chamber 310 and is connected to the hollow channel 211 of the corresponding brush body 210. Water in the water tank 110 is drawn through the hollow channel 211 and then sprayed out through the first conveying port 320, the first conveying chamber 310, the second conveying port 330, and the hollow channel 211 of the brush body 210 corresponding to the second conveying port 330, so that the brush body 210 has sufficient water to wet and clean it when it acts on the guide belt 100.

[0073] The existing water is sprayed through a nozzle set on one side of the brush roller 120. However, when the high-pressure spray from the nozzle acts on the guide belt 100 at a distance from the brush, the water and the brush body 210 cannot act on the guide belt 100 simultaneously, resulting in poor cleaning effect of the slurry. However, when the high-pressure spray from the nozzle acts on the guide belt 100 at a distance from the brush, the high-pressure water flow will impact the brush body 210, affecting the cleaning effect of the brush body 210 on other impurities. By drawing water from the water tank 110 and mixing it with air through the brush body 210 corresponding to the first conveying port 320 and spraying it out, the cleaning effect of the brush body 210 on the slurry can be further improved.

[0084] The sleeve 510 and the telescopic tube 520 are mounted on the mounting shaft 300. During the rotation of the brush assembly 200, the telescopic tube 520 is connected to the corresponding first connector 220 by the mutual attraction between the first magnet 530 and the second magnet 540. The sealing ring 550 improves the sealing of the connection position. When the first magnet 530 and the second magnet 540 cooperate with each other, the valve assembly is opened, which facilitates the communication between the first connector 220 and the second connector 400. As the brush roller 120 rotates, the telescopic tube 520 extends out of the sleeve 510. When the first limiting part 511 and the second limiting part 523 interact with each other, the first connector 220 and the second connector 400 are reset by the reset assembly, and the valve assembly is closed.

[0085] Furthermore, the reset component includes:

[0094] Valve body 592 is placed on valve seat 590;

[0095] The valve port 522 is placed on the telescopic tube 520 and is adapted to the valve body 592.

The valve body 592 is installed on the valve seat 590, and the vent 591 is connected to the first delivery chamber 310. When the first connector 220 and the second connector 400 are connected through the connecting mechanism 500, the valve body 592 and the valve port 522 are opened, so that the first connector 220 and the second connector 400 are connected.

[0097] Example 3:

[0098] like Figure 2 , Figure 3 As shown, this application embodiment provides a water washing device for a printing machine guide belt 100. In addition to the above-mentioned technical features, the mounting shaft 300 is further provided with a guide seat 700, and the side wall of the guide seat 700 is provided with a guide wall 710 adapted to the first connector 220.

[0099] The guide seat 700 is mounted on the mounting shaft 300 and connected by bolts or screws or by welding. When the brush assembly 200 rotates past the position of the guide seat 700, the first connector 220 abuts against the guide wall 710. With the movement of the brush assembly 200 and the action of the reset assembly, the brush head can have a travel along the axial direction of the mounting shaft 300, so that the brush assembly 200 can swing, thereby improving the cleaning effect of the brush body 210 on the guide belt 100.

[0100] Example 4:

[0101] like Figure 2 , Figure 3 , Figure 5As shown, this application embodiment provides a washing device for a printing machine guide belt 100. In addition to the above-mentioned technical features, the mounting shaft 300 is further provided with a protrusion 800, the protrusion 800 corresponding to the position of the cleaning needle 130, the protrusion 800 is provided with a sliding groove 810, the first connector 220 is provided with a sliding part 221 adapted to the sliding groove 810, a guide opening 820 is provided on one side of the protrusion 800, the first connector 220 is provided with an ejection mechanism 900, the protrusion 800 is provided with a plurality of connecting holes 830 evenly arranged in the sliding groove 810, the connecting holes 830 are connected to the first conveying pipe 600, the connecting holes 830 are provided with a switch seat 840, and the switch seat 840 is provided with a fourth return spring 850.

[0102] During the rotation of the brush assembly 200, the sliding part 221 of the first connector 220 is guided into the slide groove 810 through the guide opening 820. The sliding part 221 abuts against the slide groove 810 and the switch seat 840. Each connection hole 830 corresponds to a switch seat 840. When the first connector 220 moves along the slide groove 810, the air in the first delivery pipe 600 is ejected through the ejection mechanism 900 through the connection hole 830, so that the gas acts on the brush body 210, accelerating the separation of impurities on the brush body 210 from the brush body 210. When the sliding part 221 moves, the corresponding connection hole 830 opens. After moving through, the fourth reset spring 850 resets and closes the connection hole 830.

[0107] The first connector 220 is provided with a spray hole 940, which corresponds to the through hole 911.

[0108] When the sliding part 221 abuts against the sliding groove 810, the movable seat 910 retracts into the first connector 220, causing the movable seat 910 to abut against the plug 920, closing the connection between the movable seat 910 and the hollow channel 211 of the brush body 210, and connecting the through hole 911 with the nozzle, so that the gas flowing out of the connecting hole 830 is sprayed out through the nozzle 940 and acts on the brush body 210.

[0109] The second magnet 540 is mounted on the movable base 910.

[0110] Example 5:

[0111] This application also provides a control method for a water washing device of a printing machine guide belt 100, the specific steps of which include:

[0112] S1, the brush roller 120 drives the brush assembly 200 to rotate. When the first connector 220 and the second connector 400 on the brush roller 120 are engaged, high-pressure gas is blown out through the first conveying pipe 600, water is drawn from the water tank 110 through the brush body 210 on the side corresponding to the first conveying port 320, and sprayed out through the brush body 210 on the side corresponding to the second conveying port 330, sprayed onto the guide belt 100, to wet the slurry and then clean it.

[0113] S2, gas is ejected through the brush body 210 corresponding to the protrusion seat 800, and in conjunction with the cleaning needle 130, the lint and thread ends are efficiently separated from the brush body 210.

[0114] At the point where the brush body 210 contacts the guide belt 100, a mixture of water and air is sprayed out through the brush body 210, which acts on the slurry on the guide belt 100 to improve the cleaning effect on the slurry. At the point where the brush body 210 interacts with the cleaning needle 130, air is sprayed out from the first connector 220 and acts on the brush body 210, which accelerates the rapid separation of impurities such as lint and thread from the brush body 210.
