Description

Technical Field

[0001] This invention relates to the field of screen printing technology, and more particularly to a screen printing cleaning device. Background Technology

[0002] Screen printing is a widely used printing method. Its principle is based on the fact that ink can pass through the mesh openings of the screen printing plate in the image areas, while ink cannot pass through the mesh openings in the non-image areas. During printing, ink is poured into one end of the screen printing plate, and a squeegee applies pressure to the ink areas while moving at a constant speed towards the other end. As it moves, the ink is forced through the mesh openings in the image areas onto the substrate by the squeegee.

[0003] Currently, after printing, screen printing requires disassembling the screen and using large instruments for ultrasonic cleaning. After cleaning, the screen needs to be reinstalled, or workers can use a brush and absorbent paper to wipe it clean. This cleaning method is costly and time-consuming, which affects printing efficiency. Summary of the Invention

[0004] The purpose of this invention is to solve the problems mentioned in the background art of existing screen printing, which require disassembling the screen after printing and using large instruments for ultrasonic cleaning, followed by reinstallation of the screen, or workers using brushes and absorbent paper to wipe away oil, resulting in high cleaning costs and long cleaning times that affect printing efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A screen printing cleaning apparatus, comprising,

[0007] The device body has a printing component connected to its upper end, and a cleaning mechanism is fitted onto the upper end of the printing component. The cleaning mechanism includes an upper plate, an upper brush plate inserted inside the upper plate, and a groove formed on the outer surface of the upper brush plate.

[0008] An oil control mechanism, located at one end of the cleaning mechanism, is used for metered oil supply and discharge. The mechanism includes a toothed plate with rotating teeth connected to its upper end. One end of the rotating teeth is connected to a squeezing turntable. One end of the main body of the device is connected to a flexible hose, the upper end of which is connected to a limiting disc. The limiting disc contains a flexible hose, and one end of the hose is connected to an oil outlet pipe with an oil nozzle. When the upper handle pushes the brush plate at the bottom of the upper plate to scrape, it moves the toothed plate, causing it to mesh with the rotating teeth. The rotating teeth drive the squeezing turntable to rotate. The squeezing turntable is a triangular pressure block, which squeezes the flexible hose inside the limiting disc. The hose's elasticity creates a peristaltic effect, causing the oil suction port at one end of the hose to insert into the cleaning water and generate suction. The oil is then sprayed from the oil nozzle at the oil outlet pipe and falls onto the upper end of the mesh body, thus working with the brush plate to push and clean.

[0009] Preferably, the printing assembly includes a base plate, and a screen printing body is movably connected to the upper end of the base plate. The screen printing body is installed on the upper end of the base plate so that printing can be performed through the screen printing body.

[0010] Preferably, the lower end of the upper brush plate is in contact with the outer surface of the wire mesh body, and the lower end of the wire mesh body is provided with a lower brush plate. The lower brush plate is installed inside the lower plate to scrape both sides of the wire mesh body. An insert is installed at the upper end of the lower plate so that it is connected through the elastic element at the upper end of the insert, making it easy to elastically fit the upper plate onto the outside of the wire mesh body.

[0011] Preferably, the outer surface of the rotating teeth meshes with the upper end of the toothed plate, and the outer surface of the extrusion turntable cooperates with the hose. The rotation of the rotating teeth drives the extrusion turntable to rotate. The extrusion turntable is set as a triangular pressure block, which squeezes the hose inside the limiting plate. The hose elasticity produces a peristaltic effect, causing the oil suction port at one end of the hose to be inserted into the cleaning water to generate suction.

[0012] Preferably, a lower plate is inserted into the lower end of the upper plate, and an oil collection box is connected to one end of the lower plate. The lower brush plate pushes and cleans the bottom of the wire mesh body, so that the cleaning liquid flows into the oil collection box for collection.

[0013] Preferably, an insert is installed on the lower plate, and an elastic element is movably connected to the upper end of the insert. The upper plate is easily fitted onto the outside of the wire mesh body through the elastic element at the upper end of the insert.

[0014] Preferably, one end of the upper plate is provided with a fixing member, which is attached to the upper end of the upper brush plate. The upper brush plate is removed from the upper plate by the fixing member, so that the upper brush plate can be cleaned.

[0015] Preferably, the other end of the hose is connected to an oil suction port, and one end of the upper brush plate is provided with an oil storage box. The rotating teeth drive the extrusion disc to reverse, so that the hose produces a reverse suction effect, causing the sewage to be discharged from the oil outlet pipe through the reverse suction force from the oil suction port.

[0016] Preferably, the lower end of the cleaning mechanism is provided with a guide component, the guide component includes a roller groove, the lower end of the upper plate is connected to a slider, the roller groove is opened at the upper end of the wire mesh body, the slider is installed at the lower end of the upper plate, and the slider is driven by a ball bearing installed at the bottom of the slider to make the slider drive the upper plate to slide in a direction, so as to prevent the cleaning from deviating.

[0017] Preferably, the lower end of the slider is movably connected to a ball bearing, the outer surface of which cooperates with the groove. The slider drives the upper plate to slide in a specific direction, preventing the cleaning process from deviating and thus improving the cleaning stability.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This invention installs a printing assembly on the upper part of the device body and a screen body on the upper part of the base plate, allowing printing to be performed on the screen body. When the screen body needs to be cleaned, the upper plate is fitted over the outside of the screen body, scraping both sides of the screen body. The cleaning oil with stains accumulates on the upper brush plate and flows into the oil collection box along the groove on the outer surface of the upper brush plate. An oil control mechanism is provided at one end of the cleaning mechanism, which sucks in the cleaning oil and sprays it onto the screen body through the squeezing assembly. The upper and lower brush plates scrape and clean the screen body. When the upper plate is pushed to the bottom of the screen body, it is pulled back, causing the toothed plate to rotate in reverse, so that the sewage is discharged from the oil outlet pipe by reverse suction and discharged from the oil suction port. This achieves the effect of quickly cleaning the screen body and saving cleaning efficiency.

[0020] A guide assembly is installed at the lower end of the upper plate. A roller groove is opened at the upper end of the screen body, and a slider is installed at the lower end of the upper plate. A ball bearing is installed at the bottom of the slider, which causes the slider to drive the upper plate to slide in a direction, preventing the cleaning from deviating and achieving the effect of improving cleaning stability.

Example

[0036] Please refer to Figure 1 - Figure 9 A screen printing cleaning device, comprising,

[0037] The device consists of a main body 1, with a printing assembly 2 connected to its upper end. A cleaning mechanism 3 is fitted onto the upper end of the printing assembly 2. The cleaning mechanism 3 includes an upper plate 31, with an upper brush plate 33 inserted inside the upper plate 31. The outer surface of the upper brush plate 33 has a groove 34. This groove 34 allows cleaning oil with dirt to accumulate at the upper end of the upper brush plate 33 when it is pushed, and then flow into the oil collection box 49 along the groove 34 on the outer surface of the upper brush plate 33 for collection.

[0038] An oil control mechanism 4 is located at one end of the cleaning mechanism 3 for quantitative oil supply and discharge. The oil control mechanism 4 includes a toothed plate 41, with a rotating tooth 42 connected to the upper end of the toothed plate 41. One end of the rotating tooth 42 is connected to a pressing turntable 43. One end of the device body 1 is connected to a hose 45, with a limit plate 44 connected to the upper end of the hose 45. The limit plate 44 contains the hose 45, and one end of the hose 45 is connected to an oil outlet pipe 46. The oil outlet pipe 46 has an oil spray nozzle 47. The oil control mechanism 4 at one end of the cleaning mechanism 3 allows cleaning oil to be drawn in and sprayed onto the screen body 22 via the pressing assembly. This, combined with the upper brush plate 33 and lower brush plate 36, scrapes and cleans the screen body 22, removing oil from its upper surface. The oil control mechanism 4 at one end of the printing assembly 2 allows the oil to be drawn in and sprayed onto the screen body 22 via the upper plate. One end of 31 is fixedly connected to the toothed plate 41, so that when the handle at the top of the upper plate 31 pushes the brush plate 33 at the bottom of the upper plate 31 to scrape, the toothed plate 41 is moved, so that the toothed plate 41 meshes with the rotating teeth 42. The rotation of the rotating teeth 42 drives the extrusion turntable 43 to rotate. The extrusion turntable 43 is set as a triangular pressure block, so that the hose 45 inside the limiting plate 44 is squeezed. The hose 45 elastically generates a peristaltic effect, so that the oil suction port 48 at one end of the hose 45 is inserted into the cleaning water to generate suction, and sprayed out from the oil spray port 47 at one end of the oil outlet pipe 46, falling into the upper end of the screen body 22, so that it works with the brush plate 33 to push and clean. When it is pushed to the bottom of the screen body 22, the cleaning water mixed with printing impurities flows from the slope groove 34 on the upper surface of the brush plate 33 into the oil collection box 49 for collection.

[0039] The printing assembly 2 includes a base plate 21, and a screen body 22 is movably connected to the upper end of the base plate 21. The screen body 22 is installed on the upper end of the base plate 21 so that printing can be performed through the screen body 22.

[0040] The lower end of the upper brush plate 33 is in contact with the outer surface of the screen body 22. The lower end of the screen body 22 is provided with a lower brush plate 36. The lower brush plate 36 is installed inside the lower plate 32 so that the two sides of the screen body 22 can be scraped. The upper end of the lower plate 32 is installed with a plug 37 so that the upper plate 31 can be elastically fitted onto the outside of the screen body 22 through the elastic element 38 at the upper end of the plug 37.

[0041] The outer surface of the rotating tooth 42 meshes with the upper end of the toothed plate 41, and the outer surface of the extrusion disc 43 cooperates with the hose 45. The rotation of the rotating tooth 42 drives the extrusion disc 43 to rotate. The extrusion disc 43 is set as a triangular pressure block, which squeezes the hose 45 inside the limiting disc 44. The hose 45 elastically generates a peristaltic effect, which causes the oil suction port 48 at one end of the hose 45 to be inserted into the cleaning water to generate suction. The oil is sprayed out from the spray port 47 at one end of the oil outlet pipe 46 and falls into the upper end of the wire mesh body 22, which cooperates with the brush plate 33 to push and clean. The lower end of the limiting disc 44 is equipped with a twisting clamp to limit the limiting disc 44 to the side end of the device body 1.

[0042] A lower plate 32 is inserted into the lower end of the upper plate 31. One end of the lower plate 32 is connected to an oil collection box 35. A small amount of cleaning oil flows into the lower end of the screen body 22 through the screen printing slot. A lower brush plate 36 is installed inside the lower plate 32, so that the lower brush plate 36 pushes and cleans the bottom of the screen body 22, so that the cleaning liquid flows into the oil collection box 35 for collection.

[0043] A plug 37 is installed on the upper part of the lower plate 32. An elastic element 38 is movably connected to the upper end of the plug 37. A fixing element is provided at one end of the upper plate 31, which is fixed to fit against the upper end of the upper brush plate 33. A lower brush plate 36 is installed inside the lower plate 32 to scrape both sides of the screen body 22. A plug 37 is installed at the upper end of the lower plate 32, and the upper plate 31 is flexibly fitted onto the outside of the screen body 22 through the elastic element 38 at the upper end of the plug 37.

[0044] The other end of the hose 45 is connected to an oil suction port 48. One end of the upper brush plate 33 is provided with an oil storage box 49. The toothed plate 41 drives the rotating tooth 42 to reverse, which causes the rotating tooth 42 to drive the extrusion disc 43 to reverse, so that the hose 45 produces a reverse suction effect, and the sewage is discharged from the oil outlet pipe 46 by reverse suction from the oil suction port 48.

[0045] In use, this invention involves installing a printing assembly 2 at the upper end of the main body 1 and a screen printing body 22 at the upper end of the base plate 21, allowing printing to be performed through the screen printing body 22. When the screen printing body 22 needs cleaning, an upper plate 31 is fitted over the outside of the screen printing body 22. A lower plate 32 is installed at the lower end of the upper plate 31. An upper brush 33 is installed inside the upper plate 31, and a lower brush 36 is installed inside the lower plate 32, allowing for scraping of both sides of the screen printing body 22. An insert 37 is installed at the upper end of the lower plate 32, connected by an elastic element 38 at the upper end of the insert 37, facilitating the elastic fitting of the upper plate 31 over the screen printing body 2. On the outer side of the upper brush plate 33, a groove 34 is provided on the outer surface of the upper brush plate 33. When the upper brush plate 33 is pushed, the cleaning oil with stains accumulates on the upper end of the upper brush plate 33 and flows into the oil collection box 49 along the groove 34 on the outer surface of the upper brush plate 33. An oil control mechanism 4 is provided at one end of the cleaning mechanism 3, so that the cleaning oil is sucked in and sprayed onto the screen body 22 by the squeezing component. The upper brush plate 33 and the lower brush plate 36 scrape and clean the screen body 22, cleaning the upper surface of the screen body 22. An oil control mechanism 4 is provided at one end of the printing component 2. By fixing the toothed plate 41 to one end of the upper plate body 31, the upper brush plate at the bottom of the upper plate body 31 is pushed by the handle at the upper end of the upper plate body 31. When the brush 33 is scraped, it drives the toothed plate 41 to move, causing the toothed plate 41 to mesh with the rotating teeth 42. The rotation of the rotating teeth 42 drives the extrusion disc 43 to rotate. The extrusion disc 43 is set as a triangular pressure block, which extrudes the hose 45 inside the limiting disc 44. The hose 45 elastically generates a peristaltic effect, causing the oil suction port 48 at one end of the hose 45 to be inserted into the cleaning water and generate suction. The water is then sprayed out from the spray nozzle 47 at one end of the oil outlet pipe 46 and falls onto the upper end of the screen body 22, which, together with the brush plate 33, pushes and cleans. When it is pushed to the bottom of the screen body 22, the cleaning water mixed with printing impurities flows from the groove 34 on the upper surface of the brush plate 33 into the oil collection box 49 for collection. The oil nozzle 47 is inserted into the oil storage box 49. The upper plate 31 is pulled backward, causing the toothed plate 41 to drive the rotating tooth 42 to reverse. The rotating tooth 42 drives the extrusion turntable 43 to reverse, causing the hose 45 to generate a reverse suction effect. This causes the wastewater to be drawn out from the oil outlet pipe 46 through the oil suction port 48. A small amount of cleaning oil flows into the lower end of the screen body 22 through the screen printing groove. The lower brush plate 36 is installed inside the lower plate 32. The lower brush plate 36 pushes and cleans the bottom of the screen body 22, causing the cleaning liquid to flow into the oil collection box 35 for collection. This achieves the effect of quickly cleaning the screen body 22 and saving cleaning efficiency.

[0046] Please refer to Figure 6 and Figure 8The cleaning mechanism 3 has a guide component 5 at its lower end. The guide component 5 includes a roller groove 51. The lower end of the upper plate 31 is connected to a slider 52. The lower end of the slider 52 is movably connected to a ball bearing 53. The outer surface of the ball bearing 53 cooperates with the roller groove 51. By installing the guide component 5 at the lower end of the upper plate 31, opening the roller groove 51 at the upper end of the wire mesh body 22, installing the slider 52 at the lower end of the upper plate 31, and installing the ball bearing 53 at the bottom of the slider 52, the slider 52 drives the upper plate 31 to slide in a directional manner, preventing the cleaning from deviating and achieving the effect of improving cleaning stability.
