Description

Technical Field

[0001] This utility model specifically relates to the field of vacuum adsorption mechanism technology, and more specifically to a vacuum adsorption mechanism used in the glazing process. Background Technology

[0002] Dipping is a ceramic glazing technique, also known as "glazing by dipping," which involves immersing the ceramic body in glaze slurry and then removing it, allowing the glaze layer to adhere by utilizing the water absorption of the body. The thickness of the glaze layer is controlled by the water absorption rate of the body, the concentration of the glaze slurry, and the immersion time. It is suitable for thick-bodied bodies and for applying glaze to the exterior of cups and bowls. This method was commonly used for porcelain before the Ming Dynasty, and the bottom of the vessels often shows exposed clay marks.

[0003] Before the Ming Dynasty, most ceramics, including cups and bowls, were glazed using the dipping method. This method, known as glazing, is one of the basic techniques for glazing ancient porcelain. The unglazed piece is held and immersed in the glaze until a layer of glaze coats the surface, then removed. This method is suitable for thick-bodied pieces and the exterior of cups and bowls. The thickness of the glaze layer depends on the water absorption rate of the unglazed piece, the consistency of the glaze, and the immersion time. Pieces glazed using the dipping method typically leave an unglazed mark on the bottom where the handle is held.

[0004] In modern glazing processes, machines are typically used to clamp or adsorb cups and bowls. However, some adsorption mechanisms fail to consider the unique characteristics of the glazing environment. Since cups and bowls are fired, their bottoms may have small pores due to temperature variations during firing, leading to insufficient adhesion and easy detachment. Therefore, we propose a vacuum adsorption mechanism for the glazing process, addressing a key need to resolve this current technological challenge. Utility Model Content

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.

[0027] Please see Figure 1-11 In this embodiment of the present invention, a vacuum adsorption mechanism for the glazing process includes a lower adsorption plate assembly 1, the upper end of which is connected to an upper adsorption plate assembly 2; the upper end of the upper adsorption plate assembly 2 is provided with a rubber ring 3. The adsorption lower plate assembly 1 includes a base 11, which is arranged in a ring and has ventilation holes 12. The outer side of the upper end of the base 11 is provided with positioning slots 15 in a ring array. The positioning slots 15 are connected to the connecting posts 23, which are fixedly installed on the lower surface of the adsorption ring 21 in a ring array. The outer side of the upper end of the base 11 is provided with columnar grooves in a ring array. A spring 16 is fixedly installed in the columnar groove. The upper end of the spring 16 is fixedly connected to the top column 17. The top column 17 is slidably connected to the columnar groove, and the upper end of the top column 17 abuts against the lower surface of the adsorption ring 21.

[0028] By adopting the above technical solution, when in use, the lower adsorption plate assembly 1 and the upper adsorption plate assembly 2 adopt a quick-installation structure with positioning slot 15, connecting column 23 and spring top column. There is no need for complex connecting parts such as bolts. Fixing can be completed by simply docking and rotating, which greatly shortens the disassembly and assembly time. At the same time, the rubber ring 3 can be quickly engaged with the connecting slot 25 through the connecting teeth 33. Different sizes of rubber ring 3 can be replaced according to the workpiece specifications to adapt to workpieces of different diameters and thicknesses, meeting the rapid switching requirements of flexible production lines.

[0029] In this embodiment, the base 11 has an annular cavity 13 inside, which is connected to the vent 12; both sides of the upper end of the annular cavity 13 are provided with sealing ring grooves 14, and sealing rings are provided in the sealing ring grooves 14. The sealing ring groove 14 is provided on the base 11; the adsorption ring 21 is provided with a plurality of adsorption holes 22 in a ring array, and the adsorption holes 22 are provided at the upper end of the ring cavity 13. The adsorption holes 22 arranged in a ring array are provided with docking rings 24 on both sides of the upper end, and the docking rings 24 are provided with connecting slots 25 arranged in a ring array. The connecting slots 25 arranged in a ring array are connected to the connecting teeth 33, which are arranged in a ring array on the lower surface of the sealing rubber ring 31, and there are two sets of them. The sealing rubber ring 31 is provided with adsorption openings 32 arranged in a ring array, and the adsorption openings 32 are corresponding to the adsorption holes 22.

[0030] By adopting the above technical solution, the sealing ring groove 14 of the base 11 contains a built-in sealing ring to block the airflow leakage of the annular cavity 13; the sealing rubber ring 31 of the rubber ring body 3 is in close contact with the surface of the workpiece to avoid air pressure loss at the adsorption opening 32; the double sealing works together to effectively prevent vacuum leakage and ensure that the workpiece remains stably adsorbed during the glazing process, avoiding workpiece detachment or displacement due to insufficient adsorption force; the sealing rubber ring 31 is made of flexible rubber material, which can form a buffer when in contact with the workpiece, further protecting the surface quality of the workpiece; Both the adsorption holes 22 and the adsorption openings 32 adopt a ring array design and are precisely aligned. The negative pressure airflow can be evenly applied to the workpiece surface through the holes of the ring array, ensuring that the adsorption force in each area of ​​the workpiece is consistent and avoiding workpiece deformation caused by uneven adsorption force. At the same time, the uniform adsorption force can ensure the stability of the workpiece posture during the glazing process, allowing each surface of the workpiece to fully contact the oil, improving the uniformity of glazing and enhancing the effect of the glazing process.

[0031] In this embodiment, the top end of the positioning slot 15 is a cylindrical feed inlet 151, and the other end is rectangular. The diameter of the feed inlet 151 is greater than the width of the rectangle. A limiting groove 152 is provided at the bottom of the feed inlet 151. The width of the limiting groove 152 is the same as the diameter of the feed inlet 151. A limiting slot 153 is provided above the end of the limiting groove 152 away from the feed inlet 151. The diameter of the limiting slot 153 is the same as that of the feed inlet 151.

[0032] By adopting the above technical solution, when the connecting column 23 matches the positioning slot 15, after the connecting column 23 enters along the feed port 151 of the positioning slot 15, the adsorption ring 21 rotates. At this time, the connecting column 23 moves to the other end along the limiting groove 152. After reaching the top, under the action of the spring 16 and the top column 17, it pushes the adsorption ring 21 to move upward. At this time, the connecting column 23 will be pulled into the interior of the limiting slot 153 for limiting. To disassemble, simply press down the adsorption ring 21 as a whole and then rotate it in the opposite direction to complete the disassembly process.

[0033] The working principle of this utility model is as follows: First, the internal assembly of the lower adsorption plate assembly 1 is completed. A sealing ring is embedded in the sealing ring groove 14 of the base 11 to ensure the airflow sealing of the annular cavity 13. Then, the spring 16 is fixedly installed in the annular array columnar groove on the outer side of the upper end of the base 11, and the top column 17 is fixed to the upper end of the spring 16 to ensure that the top column 17 can slide smoothly along the columnar groove. Next, the rubber ring 3 is connected to the upper adsorption plate assembly 2. The annular array connecting teeth 33 on the lower surface of the sealing rubber ring 31 are engaged with the connecting groove 25 of the upper end docking ring 24 of the adsorption ring 21, so that the adsorption opening 32 is precisely aligned with the adsorption hole 22 of the adsorption ring 21, and the pre-fixation of the upper plate and the rubber ring is completed. The adsorption ring 21 of the upper adsorption plate assembly 2 is connected to the base 11 of the lower adsorption plate assembly 1. At this time, the lower surface of the adsorption ring 21 presses the top post 17, causing the spring 16 to be compressed and moved downward along the cylindrical groove. At the same time, the annular array of connecting posts 23 on the lower surface of the adsorption ring 21 is aligned with the positioning slot 15 on the outer side of the upper end of the base 11. When the connecting post 23 matches the positioning slot 15, the connecting post 23 enters along the feed port 151 of the positioning slot 15 and rotates the adsorption ring 21. At this time, the connecting post 23 moves to the other end along the limiting through groove 152. After reaching the top, under the action of the spring 16 and the top post 17, it pushes the adsorption ring 21 upward. At this time, it will pull the connecting post 23 into the interior of the limiting slot 153 for limiting, and at the same time cancel the fit gap between the connecting post 23 and the positioning slot 15, further strengthening the connection stability between the adsorption ring 21 and the base 11 and preventing the assembly from loosening. After the components are assembled, the workpiece to be glazed is placed above the sealing rubber ring 31 of the rubber ring body 3, so that the workpiece covers the adsorption opening 32. Negative pressure is introduced into the annular cavity 13 through the vent 12 of the base 11. The airflow diffuses through the annular cavity 13 to the adsorption hole 22 of the adsorption ring 21, and then acts on the surface of the workpiece through the adsorption opening 32 of the rubber ring body 3. Since the sealing rubber ring 31 is in close contact with the surface of the workpiece, and the sealing ring in the sealing ring groove 14 blocks the airflow leakage of the annular cavity 13, a stable air pressure difference is formed between the upper and lower surfaces of the workpiece, thereby achieving vacuum adsorption and fixation of the workpiece. Subsequently, the adsorption mechanism and the workpiece can be sent into the glazing equipment to complete the glazing process. After glazing, the workpiece can be quickly removed by releasing the negative pressure state of the vent 12, completing one work cycle. When in use, the lower adsorption plate assembly 1 and the upper adsorption plate assembly 2 adopt a quick-installation structure with positioning slots 15, connecting posts 23 and spring top posts. There is no need for complex connecting parts such as bolts. Fixing can be completed simply by docking and rotating, which greatly shortens the disassembly and assembly time. At the same time, the rubber ring 3 can be quickly engaged with the connecting slots 25 through connecting teeth 33. Different sizes of rubber ring 3 can be replaced according to the workpiece specifications to adapt to workpieces of different diameters and thicknesses, meeting the rapid switching requirements of flexible production lines. The sealing ring 14 of the base 11 has a built-in sealing ring to block airflow leakage in the annular cavity 13; the sealing rubber ring 31 of the rubber ring body 3 fits tightly against the surface of the workpiece to avoid air pressure loss at the adsorption opening 32; the double sealing works together to effectively prevent vacuum leakage and ensure that the workpiece remains stably adsorbed during the glazing process, avoiding workpiece detachment or displacement due to insufficient adsorption force; the sealing rubber ring 31 is made of flexible rubber material, which can form a buffer when in contact with the workpiece to further protect the surface quality of the workpiece. Both the adsorption holes 22 and the adsorption openings 32 adopt a ring array design and are precisely aligned. The negative pressure airflow can be evenly applied to the workpiece surface through the holes of the ring array, ensuring that the adsorption force in each area of ​​the workpiece is consistent and avoiding workpiece deformation caused by uneven adsorption force. At the same time, the uniform adsorption force can ensure the stability of the workpiece posture during the glazing process, allowing each surface of the workpiece to fully contact the oil, improving the uniformity of glazing and enhancing the effect of the glazing process.
