DETAILED DESCRIPTION

[0033] The present application is further described in detail below with reference to the accompanying drawings.

[0034] The present application discloses a rotary screen printing machine, which is used to improve the cleaning efficiency of the rotary screen printing machine while ensuring the cleaning effect.

[0035] refer to Figure 1 A rotary screen printing machine includes a machine body 110 and a rotary screen printing roller 111 arranged on the machine body 110, wherein a scraper structure and a cleaning structure 130 are arranged on the machine body 110, and the scraper structure is detachably arranged on the machine body 110, and the scraper structure is used to scrape off the residual slurry on the inner wall of the rotary screen printing roller 111; the cleaning structure 130 is used to clean the residual slurry on the machine body 110 and the rotary screen printing roller 111, thereby improving the cleaning effect and improving the cleaning efficiency of the rotary screen printing machine, thereby achieving the purpose of improving the working efficiency of the rotary screen printing machine and reducing maintenance costs.

[0036] Specifically, refer to Figure 1 、 Figure 2 and Figure 3The scraper structure includes a scraper seat 120, a scraper driving member 121 and a scraper 124. Connecting ears 125 extend from both sides of the scraper seat 120. The connecting ears 125 are connected and detachably mounted on the body 110 by fixing bolts 126, which are convenient for quick disassembly and adjustment. The scraper driving member 121 includes a drive motor 122 and a drive roller 123. The drive motor 122 can be a servo motor or a stepper motor, and its power must be sufficient to drive the scraper 124 to move. The drive motor 122 is arranged at one end of the scraper seat 120, and the drive roller 123 is coaxially arranged at the end of the scraper seat 120 away from the drive motor 122. The output of the drive motor 122 passes through the scraper seat 120 and is coaxially connected to the drive roller 123. The drive motor 122 transmits power to the drive roller 123.

[0037] In addition, reference Figure 1 and Figure 4 The scraper 124 and the driving roller 123 are connected by an elastic member 127. The length direction of the scraper 124 is parallel to the axial direction of the driving roller 123. A groove 128 for embedding the elastic member 127 is opened on the driving roller 123 along the radial direction of the driving roller 123. The length direction of the embedding groove 128 is opened along the axial direction of the driving roller 123. One end of the elastic member 127 is connected to the bottom of the embedding groove 128, and the other end of the elastic member 127 is connected to the scraper 124. The scraper 124 is partially embedded in the embedding groove 128. The blade surface of the scraper 124 is used to contact the inner wall of the rotary screen printing roller 111 to ensure that the scraper 124 always maintains a good contact state with the inner wall of the rotary screen printing roller 111.

[0038] Specifically, the scraper 124 includes but is not limited to two forms: metal plate or rubber strip. The metal plate scraper 124 has higher hardness and is suitable for removing harder residues, such as resin substances; the rubber strip scraper 124 has a certain flexibility and is suitable for removing soft and sticky residues, such as paste.

[0039] In this embodiment, in order to enhance the adaptability of the scraper 124, the elastic member 127 is a plurality of connecting springs, and the plurality of connecting springs are arranged in the embedding groove 128 at equal intervals along the length direction of the embedding groove 128. One end of the connecting spring is connected to the bottom of the embedding groove 128, and the other end is connected to the scraper 124. When the size of the rotary screen printing roller 111 changes, the scraper 124 can still stick to its surface and perform effective scraping work, thereby improving the applicability of the scraper structure.

[0040] In addition, reference Figure 1 and Figure 5An adjusting frame 112 is provided on the machine body 110, and the adjusting frame 112 is connected to the machine body 110 through four rectangular support rods 113. The cleaning structure 130 is provided on the adjusting frame 112. In this embodiment, the cleaning structure 130 and the rotary screen printing roller 111 correspond one to one. Five rotary screen printing rollers 111 are arranged parallel to each other on the machine body 110. Correspondingly, a total of five groups of cleaning structures 130 are provided, and the cleaning structure 130 is located directly above the rotary screen printing roller 111.

[0041] Specifically, the cleaning structure 130 includes a nozzle 131 and a cleaning liquid storage tank 132. In order to further improve the cleaning effect, five groups of screw slider assemblies 140 are provided on the adjusting frame 112. The five groups of screw slider assemblies 140 correspond one to one with the five rotary screen printing rollers 111. The screw slider assembly 140 includes a screw 141, a screw motor 142, a guide rod 143 and a sliding block 144. The screw motor 142 is arranged on one side of the adjusting frame 112. The screw 141 and the guide rod 143 are arranged parallel to each other and parallel to the axial direction of the rotary screen printing roller 111. Both ends of the guide rod 143 are fixedly connected to the adjusting frame 112. One end of the screw 141 is axially fixed and circumferentially rotatably connected to the adjusting frame 112. The other end of the screw 141 passes through the adjusting frame 112 and is coaxially connected to the output shaft of the screw motor 142. The guide rod 143 and the screw 141 are both passed through the sliding block 144.

[0042] The cleaning liquid storage tank 132 is arranged on the top of the sliding block 144. The cleaning liquid storage tank 132 can be a plastic water storage barrel or a stainless steel pressure vessel, which is used to store cleaning liquid and supply it to the nozzle 131 through a pipe; the nozzle 131 is installed at the bottom of the sliding block 144 so as to cover the surface of the rotary screen printing roller 111 in all directions. The nozzle 131 is connected to the cleaning liquid storage tank 132 through a hose 133. The hose 133 is connected to an air pump 134 to facilitate the cleaning liquid storage tank 132 to supply cleaning liquid to the nozzle 131. The end of the nozzle 131 away from the hose 133 is facing the body 110 and the rotary screen printing roller 111.

[0043] The screw motor 142 works to drive the screw 141 to rotate, thereby driving the sliding block 144 to slide back and forth along the axial direction of the rotary screen printing roller 111, so that the nozzle 131 can move back and forth along the axial direction of the rotary screen printing roller 111, achieving spray coverage in a wider area. Compared with static single-point spraying, this dynamic spraying mode can reduce the probability of residual dye not being thoroughly cleaned.

[0044] Further, refer to Figure 1 、 Figure 3 and Figure 6The machine body 110 is provided with a wastewater recovery tank 114, and there are two wastewater recovery tanks 114.

A negative pressure member is provided on the machine body 110, and the negative pressure member is connected to the tank wall of the wastewater recovery tank 114. The negative pressure member can be an air pump 134, which is embedded in the machine body 110. The two negative pressure members are symmetrically arranged on both sides of the wastewater recovery tank 114. The tank walls on both sides of the wastewater recovery tank 114 are liquid-impermeable and gas-permeable. The cleaning liquid sprayed by the nozzle 131 sprays the machine body 110 and the rotary screen After the printing roller 111, water will accumulate on the machine body 110, and the negative pressure part will accelerate the cleaning liquid to enter the wastewater recovery tank 114; a waste pipe 115 is connected to the outer wall of one side of the wastewater recovery tank 114, and the end of the waste pipe 115 away from the wastewater recovery tank 114 is connected to the wastewater collection tank 116, and the waste pipe 115 and the wastewater collection tank 116 are detachably connected. In this embodiment, the connection position of the waste pipe 115 is located on the symmetry axis of the wastewater recovery tank 114, and the bottom of the wastewater recovery tank 114 is inclined at both ends toward the middle, so that the cleaning liquid after cleaning can flow from the waste pipe 115 to the wastewater collection tank 116.

[0045] A filter bucket 117 is provided on the body 110. The bottom of the filter bucket 117 is a filter net. The filter bucket 117 can be detachably placed in the wastewater recovery tank 114. In this embodiment, connecting blocks 118 extend horizontally on both sides of the filter bucket 117. Connecting bolts 119 are passed through the connecting blocks 118. The connecting bolts 119 pass through the connecting blocks 118 and are threadedly connected to the body 110.

[0046] The implementation principle of a rotary screen printing machine in an embodiment of the present application is as follows: by introducing a detachable scraper structure and a cleaning structure 130 with an adjustable nozzle 131, the problem of incomplete cleaning of the existing spray cleaning system is solved; after the scraper structure scrapes off the residual slurry adhering to the inner wall of the rotary screen printing roller 111, the residual slurry on the machine body 110 and the rotary screen printing roller 111 is cleaned in conjunction with the cleaning spray structure, and the movable design of the nozzle 131 enhances the flexibility of the cleaning structure; in summary, the rotary screen printing machine in an embodiment of the present application improves the cleaning force, improves the cleaning effect, and improves the cleaning operation efficiency of the rotary screen printing machine.
