Description

Technical Field

[0001] The present invention relates to the technical field of ceramic cup processing, and particularly to a ceramic cup coloring device. Background Art

[0002] A ceramic cup is a cup made of ceramic, which is a vessel used to hold wine, water, tea, etc. In the production process of ceramic cups, coloring is a key link to improve the aesthetic value and market value of products. Traditional coloring methods for ceramic cups mostly adopt manual operation, which not only has low efficiency, but also the coloring quality is easily affected by human factors, and it is difficult to achieve a uniform coloring effect. In addition, there are also safety hazards in the manual coloring process. For example, improper operation may cause pigment spattering or personnel injury. With the continuous development of technology, more and more industries have begun to introduce semi-automatic equipment, such as semi-automatic ceramic cup coloring devices.

[0003] According to "A Ceramic Cup Coloring Device" provided by Chinese Patent Authorization Publication No. CN222132395U, a ceramic cup to be colored can be placed on a rotating disk, and the position of a micro-pressure sensor can be adjusted through a lifting carriage and a slide rail on the upper end surface of a ceramic coloring table, so that the sensing contact of the micro-pressure sensor contacts the cup surface of the ceramic cup. Then, the lifting carriage is slowly moved to the right, and when the force exerted by the sensing contact of the micro-pressure sensor on the cup surface of the ceramic cup reaches an appropriate coloring force, the slide table is adjusted to drive the support frame to move backward, and the coloring roller moves to the position of the micro-pressure sensor and contacts the cup surface of the ceramic cup. The rotating disk drives the ceramic cup to rotate, and the rotating ceramic cup drives the coloring roller to rotate, so that the left roller surface of the coloring roller is sprayed with pigment through the nozzle in the spraying hood cavity and then rotates out to smear and color the cup surface of the ceramic cup.

[0004] Although this patent makes the sensing contact of the micro-pressure sensor flush with the rear end of the coloring roller contact the cup surface of the ceramic cup, and by adjusting the magnitude of the force sensed by the sensing contact of the micro-pressure sensor, the coloring roller colors the cup surface of the ceramic cup evenly with the same force. However, this device can only color circular ceramic cups, and it is difficult to color the outer surface of ceramic cups with handles, and the ceramic cup needs to be placed on the rotating disk for use, that is, it is also difficult to color the bottom of the ceramic cup. Therefore, there are certain defects in coloring ceramic cups with this device, and the colored ceramic cups need a certain time to dry automatically, which takes a long time.

Detailed implementation method

[0030] Example 1, consisting of Figures 1-10Provided is a coloring device for ceramic cups, including a machine body 1. A PLC control board 3 is fixed to the front of the machine body 1 and is electrically connected to an external power supply for controlling the operation of the entire device. A placement table 2 is fixed to the upper front part of the machine body 1 for placing ceramic cups of any type to be colored. Support frames 4 are fixed to both sides of the machine body 1. A displacement structure 5 is fixed to the top of the support frames 4. One side of the bottom of the displacement structure 5 is drivingly connected to an air inflation clamping structure 9 for clamping and moving the ceramic cup. A coloring pool 6 is formed on one side of the top of the machine body 1, and pigment liquid is injected into it for coloring the ceramic cup. A drain pipe 61 is fixedly penetrated through the lower part of the coloring pool 6, and a control valve is installed on the drain pipe 61 for discharging or replacing the pigment liquid. A collection pool 10 is formed near the coloring pool 6 at the top of the machine body 1 for collecting excess pigment liquid. A liquid outlet hole 101 is formed between the collection pool 10 and the coloring pool 6 so that the excess pigment liquid can flow back into the coloring pool 6. Slide grooves 11 are formed on both sides of the top of the machine body 1 where the collection pool 10 is located. Two heating structures 8 are symmetrically arranged between the two slide grooves 11 for drying the colored ceramic cups. A transmission cleaning structure 7 is installed between the placement table 2 and the heating structure 8 at the top of the machine body 1 for cleaning the dust on the surface of the ceramic cup during its movement. The transmission cleaning structure 7 is drivingly connected to one of the heating structures 8, and the cleaning structure can move synchronously when the heating structure 8 moves, improving work efficiency.

[0031] In this embodiment, the displacement structure 5 includes a mounting frame 51 fixed to the tops of the two support frames 4. A threaded rod 54 is rotatably connected inside the mounting frame 51. A stepping motor 52 is fixed to the front end of the mounting frame 51. The output shaft of the stepping motor 52 penetrates through the mounting frame 51 and is drivingly connected to the threaded rod 54. A displacement seat 53 is slidably connected inside the mounting frame 51. The displacement seat 53 is in threaded transmission connection with the threaded rod 54. When the stepping motor 52 is started, it will drive the threaded rod 54 to rotate, and then the displacement seat 53 will move axially along the threaded rod 54 inside the mounting frame 51. A baffle is fixed to the top of the displacement seat 53 for blocking the light of the photoelectric sensor 55. A double-axis cylinder 56 is fixed to the bottom of the displacement seat 53. The double-axis cylinder 56 is connected to an external air pump station through a hose for air supply. The bottom of the double-axis cylinder 56 is fixedly connected to the air inflation clamping structure 9 for pushing the air inflation clamping structure 9 to move up and down.

[0032] Among them, photoelectric sensors 55 are fixed to both sides of the middle part of the top of the mounting frame 51. The photoelectric sensors 55 and the two heating structures 8 are on the same vertical center line, and the photoelectric sensors 55 cooperate with the baffle for detection; during the movement, when the baffle on the displacement seat 53 first blocks the light of the photoelectric sensor 55, the signal will not be triggered. When the baffle on the displacement seat 53 secondarily blocks the light of the photoelectric sensor 55 and triggers the signal, the heating structure 8 is controlled to work.

[0033] In this embodiment, the inflatable clamping structure 9 includes an inflation head 91 fixedly installed on the double-axis cylinder 56. An input end 911 is provided on the back of the inflation head 91. A connecting hose is connected to an external air pump station for gas transmission. A ranging sensor 95 is fixed to the side end of the input end 911 for detecting the distance between the inflation head 91 and the ceramic cup. A hollow shaft 92 is fixedly communicated with the bottom of the inflation head 91. A flow dividing seat 93 is fixedly communicated with the bottom of the hollow shaft 92. Three sides of the flow dividing seat 93 are fixedly communicated with telescopic airbag seats 94. The telescopic airbag seats 94 can expand and extend to clamp the ceramic cup after being inflated. And the surface of the telescopic airbag seat 94 is provided with concave and convex points, which can increase the friction with the ceramic cup and improve the clamping effect.

[0034] Specifically, when the PLC control board 3 receives the coloring instruction, it will control the double-axis cylinder 56 to extend, push the inflatable clamping structure 9 to move downward to the ceramic cup on the placing table 2, then control the external air pump station to supply gas to the input end 911 of the inflation head 91, inflate the telescopic airbag seat 94 to make it expand and extend to clamp the ceramic cup, then control the double-axis cylinder 56 to contract to lift the clamped ceramic cup, and clean the surface dust when passing through the displacement structure 5. Finally, it moves above the coloring pool 6 for coloring. After the coloring is completed, the PLC control board 3 will control the double-axis cylinder 56 to extend again, move the colored ceramic cup between the two heating structures 8 above the collection pool 10. At this time, the electric baking lamp 85 in the heating structure 8 can be started to dry the ceramic cup. At the same time, the transmission cleaning structure 7 will continue to work to clean the excess pigment on the surface of the ceramic cup.

[0035] Embodiment 2, on the basis of Embodiment 1, the heating structure 8 includes a heat preservation bin 82 slidably connected in the chute 11 and a mounting plate fixed to the side end of the machine body 1. The lower part of the end face of the heat preservation bin 82 facing the transmission cleaning structure 7 is provided with an inlet and outlet slot 83. The inside of the inlet and outlet slot 83 is arranged in an arc shape up and down to adapt to the shape of the ceramic cup. An arc slot 84 is opened at the top edge of the inlet and outlet slot 83 for cooperating with the telescopic airbag seat 94 to clamp the ceramic cup. An electric baking lamp 85 is fixed to the inner side wall of the inlet and outlet slot 83 for drying the ceramic cup.

[0036] Specifically, when it is necessary to dry the ceramic cup, the PLC control board 3 will control the multi-stage electric push rod 81 to extend or contract, drive the heat preservation bin 82 to move along the chute 11 to a suitable position, and then start the electric baking lamp 85 to dry the ceramic cup. When the cleaning scraper passes through the inlet and outlet slot 83, affected by the design of the middle-narrow and both-sides-wide of the inlet and outlet slot 83, it can squeeze the sponge cloth 7241 to squeeze out the absorbed pigment liquid and drop it into the collection pool 10 to reduce the pollution to the outside.

[0037] Embodiment 3, on the basis of embodiment 2, the transmission cleaning structure 7 comprises a cleaning structure 1 71, a cleaning mechanism 2 72 and a steering structure 73, the cleaning structure 1 71 and the steering structure 73 are all mounted on the top of the machine body 1, the cleaning mechanism 2 72 is transmission mounted on the steering structure 73, the cleaning mechanism 2 72 is transmission connected to one of the heating structures 8 through the steering structure 73, the cleaning structure 1 71 comprises a U-shaped frame 1 711 fixed on the top of the machine body 1, the U-shaped frame 1 711 is internally rotatably connected with a connecting shaft 712, a sponge roller 1 713 is fixed to the outside of the connecting shaft 712, the steering structure 73 comprises a gear 1 732 and a gear 2 733 mounted on the top of the machine body 1 through a rotating shaft and a sponge roller 1 713 is fixed to the outside of the connecting shaft 712, and a gear 1 732 and a gear 2 733 are fixed to the heating structure 8 through a rotating shaft. The rack 734 on the structure 8, the gear 1 732 is meshed with the gear 2 733, the gear 2 733 is meshed with the rack 734, a connecting arm 731 is fixed above the gear 1 732 through a rotating shaft, the connecting arm 731 is fixedly connected and supported to the cleaning mechanism 2 72, the cleaning mechanism 2 72 includes a U-shaped frame 2 722 fixedly connected to the connecting arm 731, a sponge roller 2 723 is rotatably connected to the inside of the U-shaped frame 2 722 through a rotating shaft, a cleaning blade 724 is fixed below the sponge roller 2 723 through a rotating shaft, a sponge cloth 7241 is fixed on the top of the cleaning blade 724, a driving motor 721 is fixed on the top of the U-shaped frame 2 722, and the output shaft of the driving motor 721 passes through the U-shaped frame 2 722 and is transmission-connected to the rotating shaft.

[0038] Specifically, during the movement, the ceramic cup passes through the cleaning structure 1 71 and the cleaning structure 2 72 of the transmission cleaning structure 7 to clean the surface dust. The ceramic cup is located at the center between the sponge roller 1 713 and the sponge roller 2 723. When the ceramic cup moves toward the color pool 6, the ceramic cup is contacted and squeezed by the rotating sponge roller 1 713 and the sponge roller 2 723. The sponges on the surfaces of the sponge roller 1 713 and the sponge roller 2 723 rub against the ceramic cup to clean the surface dust, so that it remains clean.

[0039] When one of the heat preservation bins 82 moves, it drives the rack 734 to move, the rack 734 drives the gear 2 733, the gear 2 733 drives the gear 1 732, thereby driving the cleaning structure 2 72 on the connecting arm 731 to rotate to the side of the two heat preservation bins 82 to wait. At this time, the cleaning scraper 724 is affected by the narrow inlet and outlet grooves 83 and is difficult to directly enter the heat preservation bin 82. When the baking time is halfway, the ceramic cup is in a semi-cured state, and the PLC control board 3 drives the driving motor 721 to start, driving the sponge roller 2 723 to rotate, and the sponge roller 2 723 drives the cleaning scraper 724 to rotate. During the rotation of the cleaning scraper 724, it is squeezed into the interior of the heat preservation bin 82 through the inlet and outlet grooves 83 of the two heat preservation bins 82, and the cleaning scraper 724 contacts the bottom of the ceramic cup. By rotating the sponge cloth 7241 on the cleaning scraper 724 and contacting and rubbing with the bottom of the ceramic cup, the excess pigment liquid that has not been detached is scraped off, so that the bottom of the ceramic cup remains flat.

[0040] Among them, the first sponge roller 713 and the second sponge roller 723 are close to each other, and their exteriors are thickened sponge sleeves. When the ceramic cup passes through the first sponge roller 713 and the second sponge roller 723, the sponge sleeves are extruded and deformed, and the surface dust is cleaned up.

[0041] Working principle:

[0042] This device controls the operation of the drive system equipment through the PLC control board 3.

[0043] Initialization and placing the ceramic cup:

[0044] First, place the ceramic cup to be colored of any type on the placing table 2. There is a positioning circular line on the placing table 2 to ensure that the ceramic cup is placed in the central position. The PLC control board 3 receives power supply from an external power source and is ready to execute the preset coloring program. In the initial state, the air inflation clamping structure 9 is located above the placing table 2.

[0045] During operation:

[0046] The PLC control board 3 controls the external air pump station to supply air, so that the double-axis cylinder 56 is started, and it pushes the air inflation clamping structure 9 to move downward. The shunt seat 93 is inserted into the ceramic cup. The PLC control board 3 controls the external air pump station to supply air to the input end 911 of the air inflation head 91 to inflate the telescopic airbag seat 94, so that it expands and extends to clamp the ceramic cup, and then controls the double-axis cylinder 56 to contract to lift the clamped ceramic cup.

[0047] Next, move the ceramic cup above the coloring pool 6 through the displacement structure 5:

[0048] The PLC control board 3 then controls the stepping motor 52 to start, driving the threaded rod 54 to rotate. Since the displacement seat 53 is in threaded transmission connection with the threaded rod 54, the displacement seat 53 will move axially along the threaded rod 54 within the installation frame 51. Limiters are installed on both inner side walls of the installation frame 51 to determine the moving position. During the moving process, the ceramic cup passes through the first cleaning structure 71 and the second cleaning structure 72 of the transmission cleaning structure 7 to clean the surface dust. The ceramic cup is located at the central position between the first sponge roller 713 and the second sponge roller 723. When the ceramic cup moves towards the coloring pool 6, the ceramic cup contacts and is extruded by the rotating first sponge roller 713 and the second sponge roller 723, and the sponge on the surfaces of the first sponge roller 713 and the second sponge roller 723 rubs against the ceramic cup to clean the surface dust and keep it clean.

[0049] During the moving process:

[0050] When the baffle on the displacement seat 53 first blocks the light of the photoelectric sensor 55, a signal is not triggered. When the displacement seat 53 moves above the coloring pool 6, that is, it moves to the rear of the mounting frame 51 and its position is determined by the stopper. At this time, the double-axis cylinder 56 is controlled to extend, driving the ceramic cup downward. The ceramic cup is immersed in the pigment liquid in the coloring pool 6 to achieve full-round coloring of the outer surface. The distance from the pigment liquid is detected by the ranging sensor 95. When the set distance is reached, the double-axis cylinder 56 is controlled to stop working. At this time, the pigment liquid just reaches the edge of the cup mouth of the ceramic cup, effectively preventing the pigment liquid from entering the inside of the ceramic cup.

[0051] After immersion in the pigment liquid:

[0052] After a set time (such as X seconds), the PLC control board 3 controls the double-axis cylinder 56 to retract, driving the colored ceramic cup away from the coloring pool 6. The stepping motor 52 is restarted to drive the threaded rod 54, driving the displacement seat 53 and the colored ceramic cup to move back to their positions. During the movement, when the baffle on the displacement seat 53 first blocks the light of the photoelectric sensor 55 and triggers a signal, the PLC control board 3 controls the stepping motor 52 to stop working. Then, the two multi-stage electric push rods 81 are controlled to extend. The two multi-stage electric push rods 81 push the two heat preservation bins 82 to move along the sliding groove 11, making them close to each other. The arc-shaped grooves 84 of the two heat preservation bins 82 are combined into a circular hole that fits the hollow shaft 92. When one of the heat preservation bins 82 moves, it drives the rack 734 to move. The rack 734 drives the second gear 733, and the second gear 733 drives the first gear 732, thereby driving the cleaning structure two 72 on the connecting arm 731 to rotate to the side of the two heat preservation bins 82 and wait. At this time, due to the narrowness of the access slot 83, it is difficult for the cleaning blade 724 to directly enter the inside of the heat preservation bin 82. The colored ceramic cup is located inside the two heat preservation bins 82, and below is the collection pool 10. The excess pigment liquid on the colored ceramic cup slides into the collection pool 10 for collection and then reflows into the coloring pool 6 through the liquid outlet hole 101. At this time, the PLC control board 3 controls the electric baking lamps 85 inside the two heat preservation bins 82 to heat up, drying the colored ceramic cup for thirty minutes to achieve heat curing of the ceramic cup and make the pigment dry quickly.

[0053] During the baking process:

[0054] When baked for half the time, the ceramic cup is in a semi-cured state. The PLC control board 3 drives the driving motor 721 to start, driving the second sponge roller 723 to rotate, and the second sponge roller 723 drives the cleaning blade 724 to rotate. During the rotation of the cleaning blade 724, it is squeezed into the interior of the heat preservation bin 82 through the inlet and outlet slots 83 of the two heat preservation bins 82. The cleaning blade 724 contacts the bottom of the ceramic cup, and the sponge cloth 7241 on the rotating cleaning blade 724 contacts and rubs against the bottom of the ceramic cup to scrape off the excess pigment liquid that has not separated, keeping the bottom of the ceramic cup flat. Moreover, when the cleaning scraper passes through the inlet and outlet slot 83, due to the design of the middle being narrow and the two sides being wide in the inlet and outlet slot 83, it can squeeze the sponge cloth 7241, extruding the absorbed pigment liquid and dropping it into the collection pool 10 to reduce external pollution.

[0055] After reaching the drying time:

[0056] The PLC control board 3 controls the driving motor 721 and the electric baking lamp 85 to stop working, and controls the multi-stage electric push rod 81 to drive the heat preservation bin 82 to return to its original position. At this time, the transmission cleaning structure 7 starts to work, driving the ceramic cup to return above the placement table 2. Then control the double-axis cylinder 56 to extend, and the ceramic cup contacts the placement table 2. Then control the external air pump station to evacuate and contract the telescopic airbag seat 94 that collides, so as to separate from the ceramic cup, completing the coloring work of the ceramic cup.
