Description

Technical Field

[0001] This utility model relates to the field of ceramic craft surface waxing technology, specifically a uniform automatic waxing device for ceramic craft surfaces. Background Technology

[0002] Before firing, ceramic teacups need to be coated with wax for insulation. This is achieved using a special emulsified wax (also known as water-based wax). Areas coated with this wax on the outside of the ceramic will not absorb glaze during subsequent glazing, thus preserving the original appearance of the body. It is mainly applied to the bottom of the vessel to prevent it from sticking to the kiln slab during firing. Once the piece is fired, this wax has completely burned off, leaving no residue. Currently, the waxing process is mostly done manually, turning each cup over individually before applying the wax. The waxing speed depends entirely on the worker's skill level, making it impossible to achieve a fast, continuous production rhythm. Furthermore, manual control of the amount, application path, and thickness of wax is difficult, easily leading to poor insulation or waste. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 , 2 As shown in Figures 3, 4, 5, 6, and 7, this utility model provides a technical solution: an automatic waxing device for uniformly coating the surface of ceramic handicrafts, comprising: a belt conveyor 1; a support frame 2 fixedly connected to the top of the belt conveyor 1, a material picking component rotatably arranged in the middle of the support frame 2, the material picking component including a vacuum suction cup 6 for picking up material and a servo motor 7 for driving the angle adjustment of the vacuum suction cup 6, the end of the vacuum suction cup 6 being connected to a vacuum pump through an air duct; a waxing section located at one end of the support frame 2, the waxing section including a transversely arranged part on the support frame 2. The top movable crossbeam 8 has an n-shaped connecting frame 11 that is lifted and lowered below it. A rotating plate 13 is rotatably installed in the middle of the connecting frame 11. A servo motor 14 is fixedly connected to the middle of the rotating plate 13. A waxing sponge 15 is fixedly connected to the output end of the servo motor 14. The waxing sponge 15 consists of a U-shaped metal frame and a waxing sponge. The U-shaped metal frame is fixedly connected to the output end of the servo motor 14. When the vacuum suction cup 6 and the servo motor 14 rotate to a horizontal state, the waxing sponge 15 corresponds to the bottom of the workpiece.

[0025] It should be noted that a PLC controller is provided in this embodiment, and all servo motors are equipped with encoders. The ceramic craft water cup is conveyed forward from the top of the belt conveyor 1 at a specified angle and direction. When it reaches the bottom of the support frame 2, the vacuum suction cup 6 picks up and fixes the ceramic craft water cup downwards, then lifts it upwards. The servo motor 7 drives the end of the vacuum suction cup 6 to rotate, thereby rotating the ceramic craft water cup to a horizontal position. The waxing sponge 15, which is coated with emulsified wax, rotates to the position corresponding to the bottom of the ceramic craft water cup. The sliding of the moving beam 8 allows the wax to be applied. Sponge 15 contacts the bottom of the cup, and servo motor 3 14 drives the waxed sponge 15 to rotate, thereby applying wax to the bottom of the cup. After the bottom is waxed, the moving beam 8 drives the waxed sponge 15 to separate from the cup. Servo motor 1 7 drives the cup to tilt via vacuum suction cup 6. After adjusting the angle of the waxed sponge 15, the moving beam 8 drives the waxed sponge 15 to contact the outer wall of the cup. The bottom shape of the waxed sponge 15 applies wax to the outer wall of the cup, thereby achieving waxing of the bottom and designated outer positions of the cup. After the waxing is completed, the vacuum suction cup 6 rotates to place the cup on top of the belt conveyor 1 for continued forward transport.

[0026] In one embodiment, a dual-axis cylinder 19 is fixedly connected to the top of the belt conveyor 1 and below the support frame 2, and an infrared sensor 20 is fixedly connected to the middle of the support frame 2 and above the dual-axis cylinder 19.

[0027] It should be noted that, in this embodiment, when the ceramic craft water cup is being conveyed forward on the top of the belt conveyor 1, when the water cup corresponds with the infrared sensor 20, the infrared sensor 20 detects the corresponding signal and sends the signal to the controller. The controller controls the belt conveyor 1 to stop. At the same time, the dual-axis cylinder 3 19 extends forward and contacts the outer side of the ceramic craft water cup and the handrail through the arc-shaped rubber clamp at the end of the dual-axis cylinder 3 19, thereby achieving pushing, clamping and angle positioning, so that the ceramic craft water cup can cooperate with the vacuum suction cup 6.

[0028] In one embodiment, a water wax storage tank 16 is fixedly connected to the middle of the support frame 2 and below the waxing sponge 15. A dual-axis cylinder 17 is fixedly connected to the top of the waxing sponge 15. Two extrusion rollers 18 are provided on the top of the water wax storage tank 16. A dual-axis cylinder 17 is fixedly connected to the top of the water wax storage tank 16, and one of the extrusion rollers 18 is connected to the output end of the dual-axis cylinder 17.

[0029] It should be noted that, in this embodiment, a liquid filling pipe and a capacitive water level sensor are installed at the end of the water wax storage tank 16. The liquid filling pipe is connected to a liquid filling pump. The liquid filling pump, together with the capacitive water level sensor, can automatically fill the interior of the water wax storage tank 16. A motor heating plate is embedded inside the water wax storage tank 16, which can heat the interior of the water wax storage tank 16 when needed. One extrusion roller 18 is fixed to the top of the water wax storage tank 16, and the other is slidably installed on the top of the water wax storage tank 16. The sliding extrusion roller 18 is fixed to the dual-axis cylinder 17. When the waxing sponge 15 is inserted into the water wax storage tank 16 and moves upward, the dual-axis cylinder 17 drives one of the extrusion rollers 18 to move towards the other extrusion roller 18. In this way, the two extrusion rollers 18 squeeze the waxing sponge 15. When the waxing sponge 15 moves upward, the water wax adsorbed by the waxing sponge 15 can be squeezed out, preventing it from dripping during waxing.

[0030] In one embodiment, the material handling assembly further includes a rotating seat 3 rotatably mounted in the middle of the support frame 2, a servo motor 7 fixedly connected to one side of the support frame 2, the output end of the servo motor 7 fixedly connected to the rotating seat 3, a cylinder 4 fixedly connected to the middle of the rotating seat 3, a connecting plate 5 fixedly connected to the output end of the cylinder 4, a slide rod slidably connected to the rotating seat 3 fixedly connected to one side of the connecting plate 5, and a vacuum suction cup 6 fixedly connected to the middle of the connecting plate 5.

[0031] It should be noted that in this embodiment, when the infrared sensor 20 detects the corresponding signal, the dual-axis cylinder 3 19 simultaneously positions the water cup towards the center. Under the action of the timer, cylinder 4 drives the vacuum suction cup 6 to move downward through the connecting plate 5. Under the action of the limit switch, the vacuum suction cup 6 contacts the water cup and is fixed by suction under negative pressure. At this time, the dual-axis cylinder 3 19 resets, cylinder 4 lifts the water cup through the vacuum suction cup 6, and the servo motor 7 drives the vacuum suction cup 6 to rotate through the rotating seat 3, thereby cooperating the bottom and sides of the water cup with the waxed sponge 15.

[0032] In one embodiment, a second cylinder 9 is fixedly connected to the top of the support frame 2, and the output end of the second cylinder 9 is fixedly connected to the moving crossbeam 8. A first dual-axis cylinder 10 is fixedly connected to one side of the moving crossbeam 8, and the output end of the first dual-axis cylinder 10 is fixedly connected to the connecting frame 11. A second servo motor 12 is fixedly connected to one side of the connecting frame 11, and the output end of the second servo motor 12 is fixedly connected to the rotating plate 13.

[0033] It should be noted that in this embodiment, when the vacuum suction cup 6 is in a horizontal position, the dual-axis cylinder 10 drives the connecting frame 11 to move downwards. The connecting frame 11, through the rotating plate 13, drives the wax-coated sponge 15 downwards into the water wax storage tank 16 to contact the water wax. Under the action of the timer, the dual-axis cylinder 10 pulls the wax-coated sponge 15 out of the water wax storage tank 16 through the connecting frame 11. At this time, when the extrusion roller 18 is extruded, excess water wax can be squeezed out. The servo motor 12 drives the wax-coated sponge 15 to rotate through the rotating plate 13. The cylinder 9 drives the moving crossbeam 8 to move laterally, causing the moving crossbeam 8 to move the wax-coated sponge. 15. The cylinder moves laterally, aligning the waxed sponge 15 with the bottom of the water cup. Servo motor 3 14 drives the waxed sponge 15 to rotate, allowing it to coat the entire bottom of the cup with wax. After the bottom is coated, cylinder 2 9, via the moving beam 8, moves the waxed sponge 15 laterally to separate it from the cup. At this time, servo motor 2 12 adjusts the angle of the waxed sponge 15 via the rotating plate 13, and servo motor 1 7 tilts the cup via the rotating seat 3 and vacuum suction cup 6. When cylinder 2 9 pulls the moving beam 8, the waxed sponge 15 can contact the outside of the cup, thus coating a rectangular area of ​​the outside of the cup with wax to achieve the desired shape.
