Description

Technical Field

[0001] This utility model relates to a high-efficiency microwave drying system for electroporation glaze. Background Technology

[0002] Traditional isostatic dry glazing methods involve spray glazing. The complex umbrella shape makes spray glazing difficult, requiring extensive employee training to produce acceptable products. Product quality is inconsistent. Furthermore, the prolonged bending and meticulous spraying by employees leads to high labor intensity, fatigue, and increased defective products. To ensure sufficient glaze thickness, traditional spray glazing involves three or four coats, resulting in long manual operation times. This can cause the first-coated areas to absorb moisture and crack, leading to uneven glaze thickness and a rough surface. After glazing, the surface often exhibits a pronounced orange-peel effect. Additionally, the base of the umbrella, where the spray gun hits directly, tends to be thicker and more prone to moisture concentration, causing further cracking. Summary of the Invention

[0003] This invention provides a high-efficiency microwave drying system for electro-porcelain glazing to solve the problems existing in the prior art.

[0004] The technical solutions adopted in this utility model are as follows:

[0005] A high-efficiency microwave drying system for electroporation porcelain includes a frame, a cover, a support base, a top plate, a microwave heating unit, and a glazing machine equipped with a glazing gun. The cover is fixed to the frame and has an openable and closable door. The top plate, support base, and cover are coaxially arranged and placed inside the cover. The support base is rotatably connected to the frame. The top plate can rotate on its own and can move up and down on the frame. An umbrella-shaped blank is supported on the support base, and the top plate abuts against the umbrella-shaped blank. The glazing machine is placed outside the cover. When the door is opened, the umbrella-shaped blank is glazed using the glazing gun. When the door is closed, the glazed blank inside the cover is microwave-dried using the microwave heating unit.

[0006] Furthermore, the cover is a circular cover, including an arc-shaped fixed cover and a compartment door. The arc-shaped fixed cover is fixed to the frame, and the compartment door has an arc structure. The two compartment doors are hinged to both sides of the arc-shaped fixed cover. After the two compartment doors are close together and fit together, they together with the arc-shaped fixed cover form a cylindrical cover.

[0007] Furthermore, a latch is provided on the outer wall of one of the compartment doors, and a latch seat is provided on the other compartment door. After the two compartment doors are brought close together and fitted together, they are fixed by connecting the latch seat with the latch.

[0008] Furthermore, the inner wall of the enclosure is a metal inner wall, the microwave heating unit is a microwave heating unit with a magnetron, and a waveguide is provided on the outer wall of the enclosure. The oscillating microwaves generated by the microwave heating unit enter the inner cavity of the enclosure through the waveguide.

[0009] Furthermore, the lower end of the frame is provided with a support platform, on which a conical cover is fixed, and the support base is rotatably connected inside the conical cover.

[0010] Furthermore, a pulley unit is fixed on the frame to drive the support seat to rotate, and the rotation speed of the support seat is 80-120 rpm.

[0011] Furthermore, a slide table is slidably connected to the upper end of the frame, and a top plate is rotatably connected to the slide table.

[0012] Furthermore, the slide is driven to slide by a lead screw mechanism.

[0013] Furthermore, a rack is slidably connected to the slide, and a gear meshing with it is provided on one side of the rack. The gear is driven to rotate by a motor located on the slide. An assembly table is fixed at the bottom end of the rack, and the top plate is rotatably connected to the assembly table.

[0014] This utility model has the following beneficial effects:

[0015] (1) The glaze application method ensures that the glaze slurry can be evenly covered on the surface of the blank, effectively avoiding the problems of uneven glaze thickness, rough surface, and excessive thickness at the base of the umbrella caused by uneven manual operation in the traditional spray glazing method, thus improving the stability of product quality. Compared with the traditional repeated spray glazing method, the glazing time is greatly shortened and the glazing efficiency is improved.

[0016] (2) The microwave heating unit can generate strong oscillating microwaves, which can quickly penetrate the blank and stimulate its internal moisture to achieve efficient drying, reduce the waiting time of the blank in the drying process, and speed up the overall production pace.

[0017] (3) Compared with traditional hot air circulation drying, microwave drying technology has higher thermal efficiency and can complete the drying task in a shorter time. Moreover, microwave heating acts directly on the inside of the blank, reducing energy loss and thus achieving energy saving and emission reduction.

[0018] (4) The opening and closing of the warehouse door and the lifting and lowering of the top plate are all achieved through simple mechanical structure or motor drive, which is convenient and quick to operate. Workers can start operating after brief training, reducing the dependence on the skill level of the operators. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] like Figure 1 and Figure 2 This utility model discloses a high-efficiency microwave drying system for electric porcelain glazing, comprising a frame 1, a cover 2, a support base 3, a top plate 4, a microwave heating unit, and a glazing machine 5 equipped with a glazing gun 54.

[0023] The cover 2 is fixed to the frame 1. The cover 2 is equipped with an openable and closable door 21. The top plate 4, support base 3, and cover 2 are arranged coaxially. The top plate 4 and support base 3 are both placed inside the cover 2. The support base 3 is rotatably connected to the frame 1. The top plate 4 can rotate on its own and can move up and down on the frame 1. The umbrella-shaped blank is supported on the support base 3, and the top plate 4 abuts against the umbrella-shaped blank. The support base 3 is the driving component, and the top plate 4 is the driven component. When the top plate 4 moves down, it clamps the umbrella-shaped blank between the top plate 4 and the support base 3. During the glazing and microwave heating and drying process, the support base 3 rotates at a speed of 80-120 rpm.

[0024] The glazing machine 5 is placed outside the cover 2. The chamber door 21 is opened, and the worker holds the glazing gun 54 to perform glazing operation on the umbrella-shaped blank. The chamber door 21 is closed, and the glazed blank inside the cover 2 is microwave dried by the microwave heating unit.

[0025] The cover 2 in this utility model is a circular cover, including an arc-shaped fixed cover 20 and a compartment door 21. The arc-shaped fixed cover 20 is fixed on the frame 1. The compartment door 2 has an arc structure. The two compartment doors 21 are hinged on both sides of the arc-shaped fixed cover 20. After the two compartment doors 21 are close together and fit together, they together with the arc-shaped fixed cover 20 form a cylindrical cover 2.

[0026] To lock the two compartment doors 21, a latch is provided on the outer wall of one compartment door 21, and a latch seat is provided on the other compartment door. After the two compartment doors 21 are brought close together and fitted, they are fixed by the latch and the latch seat. The latch is a conventional structure that is often used on the cargo bed of a tricycle, and its specific structure will not be described in detail in this application.

[0027] The inner wall of the housing 2 is a metal inner wall. The microwave heating unit is a microwave heating unit with a magnetron. A waveguide is provided on the outer wall of the housing 2. The oscillating microwaves generated by the microwave heating unit enter the inner cavity of the housing 2 through the waveguide. The microwave heating unit is a conventional structure, such as the microwave oven commonly used in daily life. This application only briefly describes its main components.

[0028] The lower end of the frame 1 is provided with a support platform 11, on which a conical cover 6 is fixed. The support base 3 is rotatably connected inside the conical cover 6. During the glazing process, the glaze liquid is collected through the conical cover 6, and a drain port is provided on the conical cover 6 for discharging the glaze.

[0029] A pulley unit is fixed on the frame 1. The pulley unit includes a motor, a belt and pulleys. One pulley is fixed to the shaft on the support 3, and the other pulley is fixed to the motor shaft. The two pulleys are linked together by the belt.

[0030] This invention is applicable to umbrella-shaped blanks of different heights. The top plate 4 has a large lifting stroke, and its lifting method includes two parts. One part is that a slide table 12 is slidably connected to the upper end of the frame 1, and the top plate 4 is rotatably connected to the slide table. The slide table 12 is driven to slide through a screw mechanism, which can realize a wide range of stroke lifting.

[0031] Additionally, a rack 51 is slidably connected to the slide table 12, and a gear 52 meshes with it on one side of the rack 51. The gear 52 is driven to rotate by a motor located on the slide table. An assembly table 53 is fixed to the bottom end of the rack 51, and the top plate 4 is rotatably connected to the assembly table 53. By raising and lowering the rack 51, a small range of stroke lifting can be achieved.

[0032] Open the chamber door 21 and place the porcelain blank steadily on the support base 3. Finely adjust the position of the blank to ensure that it is precisely coaxial with the support base, laying the foundation for subsequent stable and uniform processing. Then, use the top plate 4 to reliably press the blank.

[0033] Properly mount the glazing gun 54 onto the glazing machine 5, and precisely adjust the distance between the nozzle and the surface of the workpiece to maintain it within a range of 10-15 cm, thereby ensuring that the glaze can evenly and completely cover the surface of the workpiece. Start the glazing machine, allowing the workpiece to rotate steadily with the worktable at the set speed of 80-120 rpm. At the same time, the glazing gun 54 moves uniformly from top to bottom, allowing the glaze to flow quickly and evenly from the pressure tank through the glazing pipe and the glazing gun onto the surface of the workpiece, forming a glaze layer of uniform thickness.

[0034] After completing the glazing process, smoothly close the pressure tank and the glazing button in sequence. Close the chamber door 21, at which point the enclosure 2 forms a highly sealed microwave drying chamber. Then, activate the microwave drying button. The powerful oscillating microwaves generated by the microwave heating unit are precisely introduced into the inner cavity of the enclosure 2 through the waveguide, thoroughly and efficiently drying the workpiece. The drying temperature is precisely controlled within the set temperature range according to the workpiece material and size, while the time is adjusted according to the specific parameters of the workpiece to ensure optimal drying results.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
