Description

Technical Field

[0001] The utility model relates to the technical field of ceramic tile processing equipment, in particular to a ceramic tile coating machine. Background Art

[0002] With the increasing functionalization of architectural ceramics, particularly ceramic tiles, furthering the application of film treatments to ceramic tile surfaces has become a key development path for functionalization. Thick film processes, spray glazing in spray booths, and inkjet printing are all performed before firing. This can cause any functional components in the film to react with other components at high temperatures, rendering them ineffective. The final waxing process, typically performed at room temperature, can affect the adhesion and durability of thin-film processes, making it primarily a short-term process.

[0003] In view of this, in order to reduce the impact of ceramic tile firing temperature on the functional film layer, it is best to focus the treatment of the functional film on the semi-finished ceramic tile with residual heat after firing. To this end, equipment that can realize automatic coating of ceramic tile semi-finished products is needed. Utility Model Content

[0027] Reference Figures 1 to 3 The ceramic tile coating machine of the present invention is made into the following embodiments:

[0028] A ceramic tile coating machine includes: a conveying device 100, a coating device 200, a coating liquid supply device 300 and a volatile matter treatment device 400.

[0029] The conveying device 100 has a conveying surface for supporting and conveying external ceramic tile materials. The coating device 200 is arranged above the conveying device 100. The coating device 200 includes: a rubber-coated roller 210, a coating roller 220 and a coating drive mechanism 230. The rubber-coated roller 210 and the coating roller 220 are both rotatably arranged above the conveying device 100. The coating drive mechanism 230 is used to drive the rubber-coated roller 210 and the coating roller 220 to rotate. The paint liquid supply device 300 has a liquid supply port arranged above the coating device 200.

[0030] The volatile matter treatment device 400 includes an exhaust unit 410, an air supply duct 420, and a treatment liquid tank 430. The exhaust unit 410 is located downstream of the coating device 200 along the direction in which the ceramic tile material is conveyed. One end of the air supply duct 420 is connected to the exhaust unit 410, and the other end is connected to the bottom of the treatment liquid tank 430.

[0031] During actual use, the ceramic tile material is supported and transported by the conveying device 100, and the coating liquid supply device 300 can make the coating liquid flow out from the liquid supply port and fall on the coating device 200. The coating drive mechanism 230 drives the rubber-coated roller 210 and the coating roller 220 to rotate inwardly toward each other, so that the coating liquid is evenly distributed on the lower side of the rubber-coated roller 210, thereby realizing the coating and transportation of the ceramic tile material. The exhaust unit 410 can exhaust the ceramic tile material after coating, so that the volatile matter is transported along the air supply duct 420 to the treatment liquid tank 430, and is harmlessly treated by the treatment liquid in the treatment liquid tank 430. The coating liquid reacts with the brick surface through the residual heat on the surface of the ceramic tile, and the solvent and other substances in the coating liquid will evaporate during the reaction to form volatile matter. The ceramic tile coating machine of the present invention removes volatile substances after coating through the exhaust unit 410 to prevent the volatile substances from affecting the production environment, and is adaptable to the coating process of semi-finished ceramic tiles at relatively high temperatures.

[0032] The conveying device 100 extends in the front-to-back direction. The ceramic tile coating machine also includes a frame. The conveying device 100 is installed at the upper end of the frame. In this embodiment, the conveying device 100 is a belt conveying mechanism. The conveying device 100 includes: a conveying pulley, a conveying belt and a conveying motor. The conveying pulleys are provided at the front and rear ends of the conveying device 100. The conveying belt is driven around the conveying pulleys, and the output shaft of the conveying motor is coaxially fixedly connected to the conveying pulleys. The motor drives the conveying pulleys to rotate, thereby causing the conveying belt to move in a circular motion, and the ceramic tile material is supported and conveyed by the upper belt surface of the conveying belt moving along the circulating path. In some other embodiments, the conveying device 100 can also adopt a roller conveying mechanism. The conveying surface is formed by a plurality of conveying rollers arranged in a front-to-back manner, and the plurality of conveying rollers rotate synchronously to support and convey the ceramic tile material.

[0033] The axial directions of the rubberized roller 210 and the coating roller 220 extend uniformly in the left-right direction. The rubberized roller 210 is positioned in front of the coating roller 220. In this embodiment, the outer diameter of the rubberized roller 210 is larger than the outer diameter of the coating roller 220. The axes of the rubberized roller 210 and the coating roller 220 are aligned with each other. During the forward and backward conveyance of the ceramic tile material, the lower side of the rubberized roller 210 rolls against the upper side of the ceramic tile material, allowing the coating liquid to be evenly applied to the ceramic tile material.

[0034] The outer periphery of the rubberized roller 210 is provided with a rubberized layer. The rubberized layer is made of a soft, heat-resistant elastic material, specifically heat-resistant elastic silicone. The rubberized layer has a temperature resistance range exceeding 250°C, a tensile strength of ≥8.0 MPa, a tear strength of ≥20 kN / m, a permanent deformation of ≤5%, and a linear shrinkage of 3.2-3.6%.

[0035] To accommodate varying tile thicknesses and coating thicknesses, the rubberized roller 210 and coating roller 220 are preferably vertically adjustable. In this embodiment, the coating device 200 includes a lifting frame 240 and a lifting drive mechanism 250. The rubberized roller 210 and coating roller 220 are mounted on the lifting frame 240. The lifting drive mechanism 250 is used to drive the lifting frame 240 to move vertically relative to the conveyor device 100.

[0036] Specifically, the lifting frame 240 includes an upper frame 241 and a lower frame 242. The upper frame 241 and the lower frame 242 are respectively located on the upper and lower sides of the conveyor device 100. The rubberized roller 210 and the coating roller 220 are mounted on the upper frame 241. The lifting drive mechanism 250 is located below the conveyor device 100 and connected to the lower frame 242.

[0037] The conveying device 100 is provided with connecting columns 243 extending vertically on both the left and right sides. The upper and lower ends of the connecting columns 243 are respectively fixedly connected to the upper frame 241 and the lower frame 242, so that a storage space is left between the upper frame 241 and the lower frame 242. The conveying device 100 is installed in the storage space, so that the relative position of the lifting frame 240 and the conveying device 100 in the vertical direction can be adjusted as needed. The lifting drive mechanism 250 can be installed below the conveying device 100 without hindering the transportation of ceramic tile materials.

[0038] In this embodiment, the lifting drive mechanism 250 includes a motor drive component and a manual adjustment component. The motor drive component includes a first lifting adjustment seat and a first screw-nut assembly. The manual adjustment component includes a second lifting adjustment seat and a second screw-nut assembly.

[0039] The first lifting adjustment seat is slidably connected to the frame in the vertical direction. The first screw-nut assembly is mounted on the frame in the vertical direction and is in transmission connection with the first lifting adjustment seat. The motor drive component drives the first screw-nut assembly via the motor to achieve vertical adjustment of the first lifting adjustment seat.

[0040] The second lifting adjustment seat is slidably connected to the first lifting adjustment seat in the vertical direction. The second screw nut assembly is installed on the first lifting adjustment seat in the vertical direction and is transmission-connected to the second lifting adjustment seat. The manual adjustment component has a rotating handwheel for driving the second screw nut assembly.

[0041] In actual use, the motor drive component drives the lifting frame 240 to be roughly adjusted up and down. When the lower end of the rubber-coated roller 210 approaches the upper side of the ceramic tile material, the manual adjustment component is used to perform fine adjustment so that the rubber-coated roller 210 is pressed against the upper side of the ceramic tile material with an interference of 0.5 mm.

[0042] The coating liquid needs to be evenly distributed across the underside of the rubberized roller 210. To accommodate varying coating requirements, the spacing between the rubberized roller 210 and the coating roller 220 is preferably adjustable: one of the rubberized roller 210 and the coating roller 220 is slidably positioned in the forward and backward directions. The coating device 200 also includes an aperture adjustment mechanism 260, which is used to drive the rubberized roller 210 or the coating roller 220 to move forward and backward.

[0043] In this embodiment, the rubber-coated roller 210 is rotatably mounted on the upper frame 241. The coating roller 220 is adjustable in the front-to-back direction. Specifically, the opening adjustment mechanism 260 includes an opening adjustment seat and an opening adjustment screw. The opening adjustment seat is provided on the rear side of the rubber-coated roller 210 and is slidably mounted on the upper frame 241 in the front-to-back direction. The coating roller 220 is rotatably mounted on the opening adjustment seat. The axial direction of the opening adjustment screw extends in the front-to-back direction. The opening adjustment screw is rotatably connected to the upper frame 241 and is threadedly connected to the opening adjustment seat.

[0044] In actual use, the opening adjustment screw drives the opening adjustment seat to move forward and backward, so that the coating roller 220 contacts the rubber-coated roller 210. After the outer edge of the coating roller 220 contacts the rubber-coated roller 210, it is pressed forward about 0.5 mm against the rubber-coated roller 210, so that the entire rubber-coated roller 210 can remain wet without liquid dripping.

[0045] In this embodiment, the coating drive mechanism 230 includes a first drive motor 231 and a second drive motor 232. The first drive motor 231 is fixedly mounted on the upper frame 241 and is drivingly connected to the rubberized roller 210. The second drive motor 232 is fixedly mounted on the opening adjustment seat and is drivingly connected to the coating roller 220.

[0046] In actual use, the first drive motor 231 and the second drive motor 232 respectively drive the rubber coating roller 210 and the coating roller 220 to rotate. During the coating process, the outer edge linear speeds of the rubber coating roller 210 and the coating roller 220 and the conveying speed of the conveying device 100 are kept consistent, so that the rubber coating roller 210, the coating roller 220 and the ceramic tile material maintain relative rolling and avoid relative sliding.

[0047] In a further embodiment, to improve the extraction efficiency of volatiles, the volatiles processing device 400 further includes a cover 440. The cover 440 is disposed above the conveying device 100. The exhaust unit 410 is disposed on the cover 440, and the cover 440 has an inlet and an outlet at both ends along the conveying direction.

[0048] In this embodiment, the cover 440 is provided in front of the rubber-coated roller 210. The discharge port is provided at the front end of the cover 440, and the inlet port is provided at the rear end of the cover 440 and aligned front-to-back with the rubber-coated roller 210 and the conveying device 100.

[0049] In this embodiment, the paint liquid supply device 300 includes a liquid supply pipe 310, a paint pump 320, and a paint tank 330. One end of the liquid supply pipe 310 is connected to the liquid supply port, the other end of the liquid supply pipe 310 is disposed in the paint tank 330, and the paint pump 320 is connected to the liquid supply pipe 310.

[0050] The paint pump 320 pumps the paint liquid from the paint tank 330 to the liquid supply port, where it flows onto the rubber-coated roller 210 for coating. In a further embodiment, to ensure that the paint liquid is evenly distributed on the underside of the rubber-coated roller 210, the paint supply device 300 includes a liquid outlet pipe. The liquid outlet pipe extends in a horizontal direction. The liquid outlet pipe is located above the rubber-coated roller 210 and the coating roller 220. The liquid supply pipe 310 is connected to the liquid outlet pipe. The liquid outlet pipe is provided with a plurality of liquid supply ports arranged in a horizontal direction.

[0051] After the coating liquid is transported to the liquid outlet pipe through the liquid supply pipe 310, it drips onto the rubber-coated roller 210 from multiple liquid supply ports arranged on the left and right, and is then evenly spread by the coating roller 220, so that the coating liquid on the rubber-coated roller 210 is evenly coated, and the rubber-coated roller 210 is wetted as a whole without liquid dripping.

[0052] In a further embodiment, the paint liquid supply device 300 further includes a liquid receiving pan, a recovery pipe 340, and a circulating screen. The liquid receiving pans are located on the left and right sides below the conveying device 100 to receive excess paint liquid flowing from the left and right ends of the rubberized roller 210 and the coating roller 220. The upper end of the recovery pipe 340 is connected to the liquid receiving pan and is equipped with the circulating screen. The lower end of the recovery pipe 340 is located in the paint tank 330.

[0053] Excess paint liquid can be collected by the liquid receiving pan to avoid pollution to the equipment environment. After being filtered by the circulation screen, the paint liquid in the liquid receiving pan flows into the paint box 330 through the recovery pipe 340 for recycling.

[0054] In this embodiment, the wind negative pressure of the exhaust fan unit 410 is preferably 200Pa.
