Description

Technical Field

[0001] This utility model relates to the field of powder baking technology, and in particular to a fully automatic multi-specification powder baking equipment. Background Technology

[0002] A baking machine is a professional baking equipment with a working temperature range of 0℃ in a room temperature insulated chamber or 250℃ in a room temperature. It is used for baking tobacco leaves, baking polymer clay, drying and aging electrical and electronic products, and drying, baking and heat treatment of non-flammable and explosive materials in the production of instruments, materials and semiconductors.

[0003] A search revealed that patent CN222352784U proposes a powder baking oven. This technical solution has the following problems:

[0004] The existing equipment is not convenient for changing baking trays of different specifications according to different specifications of powders during baking, because the particle size affects the heat transfer efficiency. This makes it impossible for the baking trays to adapt to density differences, thus reducing the baking effect of powders of different specifications.

[0005] To address the aforementioned issues, this utility model document proposes a fully automatic multi-specification powder baking equipment. Utility Model Content

[0006] This invention provides a fully automatic multi-specification powder baking equipment, which solves the problems of existing technology where the particle size of powders with different sizes affects the heat transfer efficiency during baking, and the equipment is not convenient to change baking trays of different specifications according to different specifications of powders, making the baking trays unable to adapt to density differences and reducing the baking effect of powders of different specifications.

[0007] This utility model provides the following technical solution:

[0008] Fully automatic multi-specification powder baking equipment, including:

[0009] A baking oven, wherein two sealed doors are rotatably connected to one side of the baking oven via hinges, two mounting slots are opened on the top side of the baking oven, and a fan is fixedly installed inside each mounting slot. Two openings communicating with the mounting slots are opened on the inner wall of the top side of the baking oven, and an electric heating grid is fixedly installed on the inner wall of each opening.

[0010] The material support mechanism in powder baking is located inside the baking oven and is used to support and lift powders of different specifications.

[0011] The material turning mechanism is located inside the baking oven and is used to turn the powder during the baking process.

[0012] In one possible design, the material support mechanism includes a baking tray, hanging blocks, hanging frames, a screw, an internally threaded cylinder, and a support swivel block. Each baking tray is disposed inside a baking oven. Two hanging blocks are welded to one side of the baking tray, and each hanging frame is welded to the inner wall of one side of the baking oven for hanging the hanging blocks to facilitate the replacement of baking trays of different specifications and to support and lift powders of different specifications. The screw is welded to the bottom side of the baking tray, the internally threaded cylinder is threaded to the outer wall of the screw, and the support swivel block is welded to the bottom end of the internally threaded cylinder for adjusting and supporting the baking tray.

[0013] In one possible design, the material turning mechanism includes a motor, a reciprocating lead screw, a fixed plate, a slide groove, a telescopic plate, a limiting rod, a mounting plate, and a turning claw. The motor is fixedly installed on the top side of the baking oven. The output end of the motor is fixed to one end of the reciprocating lead screw via a coupling. The fixed plate is welded to the top side of the baking oven. The other end of the reciprocating lead screw is rotatably connected to one side of the fixed plate. A slider that mates with the helical groove of the reciprocating lead screw is fitted on the outer wall of the reciprocating lead screw. Two telescopic plates are fixedly installed on both sides of the slider. The slide groove is opened on the top side of the baking oven for limiting the extension and retraction of the telescopic plates. The end of each telescopic plate away from the slider is welded to the inner wall of one side of the slide groove.

[0014] In one possible design, the limiting rod is welded to the bottom side of the slider, and multiple mounting plates are welded to both sides of the limiting rod. Multiple flipping claws are welded to both sides of each mounting plate to evenly flip the powder supported inside the baking tray, thereby further improving the baking efficiency. The bottom inner wall of the baking oven is provided with a limiting groove for the limiting rod to slide.

[0015] In one possible design, the oven has two ventilation holes on its bottom side, and a movable groove is provided inside the bottom side of the oven. A control plate is slidably connected inside the movable groove to control the two ventilation holes. An electric push rod is fixedly installed on the bottom side of the oven, and a drive plate is fixedly provided at the output end of the electric push rod. The top side of the drive plate is fixed to the bottom side of the control plate.

[0016] In one possible design, the inner wall of the baking oven is fixedly mounted with two mounting frames corresponding to the electric heating grid by screws, and multiple louvers are rotatably connected between the two sides of the inner wall of each mounting frame via a damping shaft.

[0017] In this application, during use, the baking oven serves as the main structure of the entire equipment. Two sealed doors are hinged to one side for easy loading and unloading of powder. Two mounting slots are located on the top side, housing a fan. An electric heating grid is fixed to the inner wall of the opening. During baking, the fan activates, drawing outside air into the mounting slots. The air is heated as it passes through the electric heating grid, creating a hot airflow. This hot airflow enters the baking oven through the opening, heating and baking the powder. Simultaneously, two mounting frames corresponding to the electric heating grid are fixed to the inner wall of the baking oven using screws. Multiple louvers, rotatably connected by damping shafts on both sides of the inner wall of these mounting frames, allow for adjustment of the direction and range of the hot airflow, tailored to the location and requirements of the powder being baked. Adjusting the angle of the louvers allows the hot airflow to act more evenly on the powder, improving the baking effect. The baking tray is used to hold the powder. A suitable baking tray can be selected according to the specifications of the powder. The hanging block on one side of the baking tray is attached to the hanging frame on the inner wall of the baking oven to complete the initial installation of the baking tray. Then, by rotating the support screw, the internal threaded cylinder is driven to rotate on the screw, thereby adjusting the height of the baking tray to place it in a suitable baking position. This provides support for the baking tray, improves the stability during baking, and facilitates the replacement of baking trays of different specifications according to different specifications of powder. This allows the baking tray to adapt to the density differences of the powder and avoids the impact of particle size on heat transfer efficiency during baking, thus improving the baking effect of powders of different specifications.

[0018] Next, the motor is turned on, driving the reciprocating screw to rotate. Because the slider works in conjunction with the helical groove of the reciprocating screw, the slider moves back and forth along the screw as it rotates. Simultaneously, the telescopic plate extends and retracts within the groove, ensuring the stability of the slider's movement and maintaining the oven's airtightness to prevent heat loss. The slider also drives the limit rod to reciprocate, causing the mounting plates on both sides of the limit rod to move accordingly. The flipping claws on both sides of the mounting plates can turn the powder in the baking tray, promoting even heating, improving baking efficiency, and preventing uneven heating that could affect the baking effect. During baking, the ventilation inside the oven is controlled as needed. Then, the electric push rod is activated, moving the drive plate, which in turn moves the control plate within the moving groove. By controlling the position of the control plate, the opening degree of the ventilation holes can be controlled, thereby adjusting the ventilation volume inside the oven and ensuring the stability and safety of the baking process.

[0019] In this utility model, the fully automatic multi-specification powder baking equipment can select a suitable baking tray according to the specifications of the powder through the material support mechanism, and hang the hanging block on one side of the baking tray on the hanging frame on the inner wall of the baking oven to achieve the initial installation of the baking tray.

[0020] In this utility model, the fully automatic multi-specification powder baking equipment can turn the powder in the baking tray through the turning mechanism, which helps to make the powder heat evenly, improve baking efficiency, and avoid poor internal heating of the powder, which would affect the baking effect.

[0021] In this invention, the baking tray can be initially installed, which makes it easy to replace the baking tray with a different size according to the different specifications of powder. This allows the baking tray to adapt to the density difference of the powder, avoids the particle size affecting the heat conduction efficiency during baking, and improves the baking effect of powder of different specifications.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Example 1

[0030] The existing problem in the field of powder baking is that the particle size of powders of different sizes affects the heat transfer efficiency during baking. In addition, it is not convenient to change the baking trays of different sizes according to different specifications of powders. As a result, the baking trays cannot adapt to density differences, which reduces the baking effect of powders of different specifications. To address this problem, this solution designs a baking device.

[0031] Please refer to Figures 1-4 Baking equipment, including:

[0032] The baking oven 1 has two sealed doors 2 connected to one side via hinges. As the main structure of the entire equipment, the baking oven 1 facilitates the loading and unloading of powder. Two mounting slots are provided on the top side of the baking oven 1, each housing a fan 18. Two openings connected to the mounting slots are provided on the inner wall of the top side of the baking oven 1, each housing an electric heating mesh 19. During baking, the fan 18 is activated, drawing in outside air into the mounting slots. The air is heated as it passes through the electric heating mesh 19, forming a hot airflow. This hot airflow enters the baking oven 1 through the openings, heating and baking the powder.

[0033] The material support mechanism in powder baking is located inside the baking oven 1 to support and lift powders of different specifications. The material support mechanism includes a baking tray 3, hanging blocks 4, hanging frames 5, screws 6, internal threaded cylinders 7, and support screws 8. Each baking tray 3 is located inside the baking oven 1. Two hanging blocks 4 are welded to one side of the baking tray 3, and each hanging frame 5 is welded to the inner wall of one side of the baking oven 1 for hanging and installing the hanging blocks 4. This facilitates the replacement of baking trays 3 of different specifications and makes it easier to support and lift powders of different specifications. The baking tray 3 is used to carry the powder. According to the specifications of the powder, a suitable baking tray 3 can be selected, and the hanging blocks 4 on one side of the baking tray 3 can be hung on the hanging frames 5 on the inner wall of the baking oven 1 to achieve the initial installation of the baking tray 3.

[0034] The screw 6 is welded to the bottom side of the baking tray 3, the internal threaded cylinder 7 is threaded to the outer wall of the screw 6, and the support block 8 is welded to the bottom end of the internal threaded cylinder 7. It is used to adjust and support the baking tray 3. By rotating the support block 8, the internal threaded cylinder 7 is driven to rotate on the screw 6, thereby adjusting the height of the baking tray 3 so that the baking tray 3 is in a suitable baking position. This helps to provide support for the baking tray 3, improves the stability during baking, and facilitates the replacement of baking trays 3 of different specifications according to different specifications of powder. This allows the baking tray 3 to adapt to the density difference of the powder and avoids the particle size affecting the heat transfer efficiency during baking, thus improving the baking effect of powders of different specifications.

[0035] A material-turning mechanism is installed inside the baking oven 1 to turn the powder material during the baking process. The mechanism includes a motor 9, a reciprocating lead screw 10, a fixed plate 11, a slide groove 13, a telescopic plate 14, a limit rod 15, a mounting plate 16, and a turning claw 17. The motor 9 is fixedly installed on the top side of the baking oven 1. The output end of the motor 9 is fixed to one end of the reciprocating lead screw 10 via a coupling. The fixed plate 11 is welded to the top side of the baking oven 1. The other end of the reciprocating lead screw 10 is rotatably connected to one side of the fixed plate 11. A slider 12 is fitted on the outer wall of the reciprocating lead screw 10 to cooperate with the spiral groove of the reciprocating lead screw 10. Two telescopic plates 14 are fixedly installed on the slider. On both sides of slider 12, grooves 13 are formed on the top side of oven 1 for limiting the extension and retraction of telescopic plates 14. The end of each telescopic plate 14 away from slider 12 is welded to the inner wall of one side of groove 13. When motor 9 is turned on, it drives reciprocating screw 10 to rotate. Since slider 12 and reciprocating screw 10 are used in conjunction with the spiral groove, and reciprocating screw 10 and slider 12 in the spiral groove are connected for transmission, when reciprocating screw 10 rotates, slider 12 will move back and forth in a straight line along reciprocating screw 10. At the same time, telescopic plates 14 are limited to extend and retract within groove 13 to ensure the stability of slider 12 movement and also to ensure the sealing of oven 1 and prevent heat release inside the oven.

[0036] The limiting rod 15 is welded to the bottom side of the slider 12. Multiple mounting plates 16 are welded to both sides of the limiting rod 15. Multiple flipping claws 17 are welded to both sides of each mounting plate 16. These are used to evenly flip the powder supported inside the baking tray 3, thereby improving the baking efficiency. The bottom inner wall of the baking oven 1 is provided with a limiting groove for the limiting rod 15 to slide. The slider 12 drives the limiting rod 15 to reciprocate. The mounting plates 16 on both sides of the limiting rod 15 also move accordingly. The flipping claws 17 on both sides of the mounting plate 16 can flip the powder inside the baking tray 3, which helps to make the powder heat evenly, improves the baking efficiency, and avoids poor internal heating of the powder, which would affect the baking effect.

[0037] This application can be used in the field of powder baking, or in other fields applicable to this application.

A control plate 25 is slidably connected inside the movable groove to control the two ventilation holes 22. An electric push rod 23 is fixedly installed on the bottom side of the baking oven 1. A drive plate 24 is fixedly installed at the output end of the electric push rod 23. The top side of the drive plate 24 is fixed to the bottom side of the control plate 25. During the baking process, the ventilation in the baking oven 1 is controlled as needed. Then the electric push rod 23 is activated, which drives the drive plate 24 to move. The drive plate 24 then drives the control plate 25 to slide in the movable groove. By controlling the position of the control plate 25, the opening degree of the ventilation holes 22 can be controlled, thereby adjusting the ventilation volume in the baking oven 1 to ensure the stability and safety of the baking process.

[0041] The inner wall of the baking oven 1 is fixed with two mounting frames 20 corresponding to the electric heating grid 19 by screws. Each mounting frame 20 has multiple louvers 21 rotatably connected between its inner walls via a damping shaft. By fixing the two mounting frames 20 to the inner wall of the baking oven 1 with screws, and by rotatably connecting the multiple louvers 21 between its inner walls via a damping shaft, the direction and range of hot airflow can be adjusted by rotating the louvers 21. The angle of the louvers 21 can be adjusted according to the position and requirements of the baking powder, so that the hot airflow can act on the powder more evenly and improve the baking effect.
