Description

Technical Field

[0001] The utility model relates to the technical field of printing and dyeing, and particularly relates to a water washing device for a flat screen printing machine. Background Art

[0002] The flat screen printing machine is an important production equipment in the textile printing and dyeing industry, especially in garment manufacturing enterprises. Taking garment printing and dyeing as an example, its production process is as follows: First, fix the white garment blank at a predetermined position on the guide belt, then start the guide belt drive device to drag the guide belt. When the garment on the guide belt stops steadily at the position aligned with the printing flat screen, the flat screen frame presses down and clings tightly to the garment. The thin round magnetic steel bars placed in the screen frame roll back and forth, and the pigment placed in the flat screen is printed onto the garment through the hollowed-out pattern.

[0003] In the prior art, the water washing device of the flat screen printing machine drives a brush roller to remove the dirt on the surface of the printing guide belt by the low-speed operation of an ordinary motor. Its basic principle is to control the rotation of the brush roller through the motor. The upper edge of the brush roller is tangent to the surface of the guide belt and clings tightly to the surface of the guide belt. The lower edge of the brush roller is immersed in the water tank. During the rotation of the brush roller, water is brought to the surface of the guide belt or a spraying device is used to make the surface of the guide belt have the effect of water washing and cleaning.

A first squeezing roller 51 is rotatably connected inside the water washing pool 11 above the second squeezing roller 52. A first fixing block 62 is fixedly connected to the top of the water washing pool 11 at one end of the first squeezing roller 51 away from the second brush roller 42. A guiding roller 61 is rotatably connected to one end of the first fixing block 62 close to the inspection cabinet 2. The brush sleeve 8 is designed in a semi-circular shape. Two groups of opposite inserting blocks 81 are provided at the semi-circular bottom edge of the brush sleeve 8. The inserting blocks 81 are designed to be adapted to the fixing grooves 43. When the device is put into use, the two groups of brush sleeves 8 are sleeved on the outer side of the first brush roller 41 through the inserting blocks 81 and the fixing grooves 43, and then the other two groups of brush sleeves 8 are sleeved on the outer side of the second brush roller 42 through the inserting blocks 81 and the fixing grooves 43. The printing guide belt is cleaned by the brush sleeves 8, and the brush sleeves 8 can be replaced according to needs, which is convenient for cleaning. The inspection cabinet 2 is convenient for future inspection and maintenance. The printing guide belt enters the water washing pool 11, passes through the bottom of the limiting roller 31, then enters between the first brush roller 41 and the second brush roller 42 and is brushed clean, then enters between the first squeezing roller 51 and the second brush roller 42 and is squeezed dry, and finally is led out of the water washing pool 11 by the guiding roller 61 to complete the water washing, which can effectively clean the printing guide belt and improve the cleaning efficiency of the water washing device.

[0027] Further, one end of the limiting roller 31 extending into the inspection cabinet 2 is fixedly connected with a first rotating shaft 3. A first transmission belt 7 is arranged on the outer side of the first rotating shaft 3. When the device is put into use, the first transmission belt 7 rotates to drive the first rotating shaft 3 to rotate, thereby driving the limiting roller 31 to rotate, so as to press the printing guide belt against the bottom of the limiting roller 31, thereby ensuring that the printing guide belt is immersed in water, which is convenient for the next cleaning.

[0028] Among them, two groups of opposite fixing grooves 43 are opened on the outer sides of the first brush roller 41 and the second brush roller 42. One end of the first brush roller 41 extending into the inspection cabinet 2 is fixedly connected with a second rotating shaft 4. The second rotating shaft 4 is connected with the first rotating shaft 3 through the first transmission belt 7. A second transmission belt 71 is arranged outside the second rotating shaft 4 at one end of the first transmission belt 7 away from the main body 1. When the device is put into use, the first transmission belt 7 rotates to drive the second rotating shaft 4 to rotate, thereby driving the first brush roller 41 to rotate, so as to clean the printing guide belt passing between the first brush roller 41 and the second brush roller 42.

[0029] Secondly, the first squeezing roller 51 is tangent to the second squeezing roller 52.

The driving end of the motor inside the motor housing 53 is fixedly connected to the third rotating shaft 5. When the device is put into use, the driving end of the motor inside the motor housing 53 rotates to drive the third rotating shaft 5 to rotate, thereby driving the second squeezing roller 52 to rotate, so as to squeeze out the water in the printed guide belt after cleaning through the first squeezing roller 51 and the second squeezing roller 52. The squeezed-out water drops into the inside of the water washing pool 11, which not only avoids splashing water during cleaning and is difficult to clean, but also saves water resources.

[0030] Furthermore, a second fixing block 63 is fixedly connected inside the maintenance cabinet 2 on the side of the motor housing 53 away from the second rotating shaft 4. One end of the second fixing block 63 close to the main body 1 is rotatably connected to a fourth rotating shaft 6. The fourth rotating shaft 6 is connected to the third rotating shaft 5 through a third transmission belt 72. One end of the guiding roller 61 away from the first fixing block 62 is fixedly connected to the fourth rotating shaft 6. When the device is put into use, the third transmission belt 72 drives the fourth rotating shaft 6 to rotate, thereby driving the guiding roller 61 to rotate, so as to lead out the printed guide belt from the inside of the water washing pool 11, thus completing the cleaning.

[0031] Furthermore, a spray head 9 is fixedly connected to the top of the main body 1 and between the second brush roller 42 and the first squeezing roller 51. A water outlet 12 is provided on the outside of the main body 1 at the end of the limiting roller 31 away from the first brush roller 41. When the device is put into use, the spray head 9 sprays water on the printed guide belt, further cleaning the printed guide belt. After cleaning, the water is discharged into the water washing pool 11 through the water outlet 12.

[0032] Furthermore, a hot air blower 91 is fixedly connected to the top of the main body 1 and between the spray head 9 and the guiding roller 61. An ultrasonic cleaner 92 is fixedly connected inside the water washing pool 11 and between the limiting roller 31 and the first brush roller 41. When the device is put into use, the hot air blower 91 completely dries the squeezed printed guide belt, which is convenient for storage. The ultrasonic cleaner 92 can make a lot of bubbles in the water inside the water washing pool 11, making the cleaning of the printed guide belt more thorough.

[0033] In this embodiment, the implementation scenario is specifically as follows: during actual use, when the device is put into use, two sets of brush sleeves 8 are sleeved on the outer side of the first brush roller 41 through the insertion blocks 81 and the fixing grooves 43, and then another two sets of brush sleeves 8 are sleeved on the outer side of the second brush roller 42 through the insertion blocks 81 and the fixing grooves 43. The brush sleeves 8 can be replaced as needed, which is convenient for cleaning. Water is discharged into the inside of the water washing pool 11 through the nozzle 9 until it submerges the first brush roller 41. The power is turned on, and the driving end of the motor inside the motor housing 53 rotates to drive the third rotating shaft 5 to rotate, thereby driving the second squeezing roller 52 to rotate, thereby driving the third transmission belt 72 to rotate, thereby driving the fourth rotating shaft 6 to rotate, thereby driving the guiding roller 61 to rotate, thereby driving the second transmission belt 71 to rotate, thereby driving the second rotating shaft 4 to rotate, thereby driving the first brush roller 41 to rotate, thereby driving the first transmission belt 7 to rotate, thereby driving the first rotating shaft 3 to rotate, thereby driving the limiting roller 31 to rotate. The printing guide belt enters the water washing pool 11 and passes through the bottom of the limiting roller 31 to ensure that the printing guide belt is immersed in water and is impacted by the bubbles produced by the sonic cleaner 92, so as to initially break up the attached dirt. Then it reaches between the first brush roller 41 and the second brush roller 42, and the printing guide belt is brushed clean by the brush sleeves 8. Then it enters the bottom of the nozzle 9 and is sprayed with water by the nozzle 9 to further deepen the cleaning degree, which can effectively clean the printing guide belt and improve the cleaning efficiency of the water washing device. Then it enters between the first squeezing roller 51 and the second squeezing roller 52, and the water in the printing guide belt after cleaning is squeezed out. The squeezed water drops into the inside of the water washing pool 11, which not only avoids splashing of water during cleaning and is difficult to clean, but also saves water resources. Then it enters the bottom of the hot air blower 91 and is completely dried by the hot air blower 91, which is convenient for storage. Finally, it is guided out of the water washing pool 11 by the guiding roller 61 to complete the cleaning. The sewage is discharged through the water outlet 12. The maintenance cabinet 2 is convenient for future inspection and maintenance. Compared with the water washing device of the existing flat screen printing machine, the overall practicability of the water washing device of the flat screen printing machine can be improved by the design of the present utility model.
