[0002] Most existing mechanical parts are coated with an anti-rust coating after production to extend their service life. After coating, the parts are dried in an oven before being put into use.
[0003] As a type of baking equipment, the main function of a baking oven is to dry the workpiece, remove the moisture, and ensure that the workpiece reaches the required degree of dryness.
[0004] When drying workpieces, existing baking machines typically place the workpieces directly on the baking rack. In actual baking, the workpieces remain in the same position for a long time, resulting in uneven heating. Utility Model Content

[0007] The oven is equipped with a placement platform for limiting the position of the workpiece, and a guide assembly is also installed inside the oven to facilitate the lifting and lowering of the workpiece in conjunction with the placement platform.
[0008] The oven is equipped with gears that work in conjunction with the guide assembly to control the rotation of the placement platform.
[0009] The guide assembly includes a limiting disk three, with a reciprocating lead screw installed at the upper middle part of the limiting disk three for guiding the placement platform, and a gear ring installed at the lower middle part of the limiting disk three for cooperating with gears to control the rotation of the placement platform.
[0010] Furthermore, the oven is equipped with a first annular limiting block and a second annular limiting block. A limiting plate is installed in the middle of the first annular limiting block. Multiple ventilation slots are opened in the middle of the limiting plate. A limiting block is installed at the bottom of the limiting plate.

[0012] Furthermore, a lifting plate is installed inside the baking oven. A sliding groove is provided on the upper left side of the lifting plate, and a rod for limiting the sealing door by cooperating with the positioning hole is installed on the upper right side of the lifting plate. A limit rod is installed on the lower end of the lifting plate.
[0013] Furthermore, a limiting sleeve is installed at the right end of the second annular limiting block, and a spring for pushing the limiting rod upward is installed inside the limiting sleeve. A limiting ring is installed on the right side of the baking oven, and a sealing gasket is installed on the right side of the limiting ring.
[0014] Furthermore, the placement platform includes a second limiting plate, and a screw nut for cooperating with a reciprocating screw to control the lifting and lowering of the second limiting plate is installed in the middle of the second limiting plate.

[0028] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.
[0029] Please see Figures 1-5 This utility model provides a workpiece movable and lifting baking machine, including a baking oven 100. A first annular limiting block 110 and a second annular limiting block 120 are fixedly installed inside the baking oven 100. The first annular limiting block 110 is located at the upper end of the inner cavity of the baking oven 100, and the second annular limiting block 120 is located at the lower end of the inner cavity of the baking oven 100.
[0030] A limiting plate 10 is movably installed in the middle of the first annular limiting block 110. The limiting plate 10 can rotate inside the first annular limiting block 110. Multiple ventilation slots 11 are opened in the middle of the limiting plate 10. Multiple limiting blocks 12 are fixedly installed at the bottom of the limiting plate 10. A heater 130 is installed at the upper end of the inner cavity of the baking oven 100. The first annular limiting block 110 divides the inner cavity of the baking oven 100 into an upper cavity and a lower cavity, and the heater 130 is installed in the upper cavity. The second annular limiting block 120 divides the lower cavity of the baking oven 100 into cavity one and cavity two. The upper cavity of the baking oven 100 is heated by the heater 130. The heat flows into the cavity one of the lower cavity through the ventilation slots 11 to heat the workpiece.
[0031] The baking oven 100 is equipped with a placement platform 200 for limiting the workpiece, and the placement platform 200 is installed in the cavity. The baking oven 100 is also equipped with a guide assembly 300 for controlling the lifting and lowering of the workpiece in conjunction with the placement platform 200.
[0032] The oven 100 is equipped with a gear 140 that works with the guide assembly 300 to control the rotation of the placement platform 200. A geared motor 141 is installed at the lower end of the gear 140 to control its rotation. A sealing door 150 is installed on the right side of the oven 100, which facilitates the handling of workpieces. A handle 151 is fixedly installed on the right end of the sealing door 150 to facilitate opening and closing. A rotating shaft 152 is installed on one side of the sealing door 150, and the sealing door 150 rotates around the axis of the rotating shaft 152. A positioning block 153 is fixedly installed on the left side of the sealing door 150, and a positioning hole 154 is provided in the middle of the positioning block 153.
[0033] The oven 100 is equipped with a lifting plate 160. A groove 162 is provided on the upper left side of the lifting plate 160. A rod 163 is fixedly installed on the upper right side of the lifting plate 160 to limit the sealing door 150 in conjunction with the positioning hole 154. A limit rod 161 is fixedly installed on the lower end of the lifting plate 160. When the rod 163 is inserted into the cavity of the positioning hole 154, the sealing door 150 cannot be opened.
[0034] A limiting sleeve 121 is fixedly installed on the upper right side of the second annular limiting block 120. A spring 122 is installed inside the limiting sleeve 121 to push the limiting rod 161 upward, so that the insertion rod 163 is always in the cavity of the positioning hole 154. A limiting ring 170 is installed on the right side of the baking oven 100, and a sealing gasket 171 is installed on the right side of the limiting ring 170 to increase the sealing performance.
[0035] The placement platform 200 includes a limiting plate 210. A screw nut 211 is fixedly installed in the middle of the limiting plate 210 to control the lifting and lowering of the limiting plate 210 in conjunction with the reciprocating screw 320. A limiting hole 214 is opened in the middle of the limiting plate 210. A fixing ring 212 for pressing down the lifting plate 160 is fixedly installed on the outer wall of the limiting plate 210. Multiple balls 213 are movably installed at the lower end of the fixing ring 212. The balls 213 can roll in the groove of the slide 162. When the fixing ring 212 presses down the lifting plate 160, it simultaneously drives the limiting rod 161 to squeeze the spring 122. The insertion rod 163 moves out from the cavity of the positioning hole 154 at the same time, releasing the limitation on the sealing door 150, so as to facilitate the handling of workpieces.
[0036] The guide assembly 300 includes a limiting disk 310. A limiting rod 312 is installed at the upper end of the limiting disk 310, and the limiting rod 312 is located in the cavity of the limiting hole 214 to limit the limiting disk 210, so that the limiting disk 210 can only move up and down at the upper end of the limiting disk 310. A heat insulation pad 311 is fixedly installed at the upper end of the limiting disk 310, and the limiting disk 310 is installed in the middle of the second annular limiting block 120. A gear ring 313 is fixedly installed at the lower middle part of the limiting disk 310 for cooperating with the gear 140 to control the rotation of the placement platform 200. The upper middle part of the limiting plate 310 is equipped with a reciprocating screw 320 for guiding the placement platform 200. The top of the reciprocating screw 320 and the limiting rod 2 312 can rotate in the middle of the limiting block 12. The lower end of the reciprocating screw 320 is equipped with a motor 321 for controlling the rotation of the reciprocating screw 320. The motor 321 is located in the cavity 2. The heat insulation pad 311 reduces the amount of heat entering the cavity 2.
[0037] When the second limiting plate 210 presses down on the lifting plate 160, the insertion rod 163 moves out of the cavity of the positioning hole 154 simultaneously, and the sealing door 150 opens the inner cavity of the baking oven 100. The workpiece is placed on the second limiting plate 210. The reduction motor 141 controls the gear 140 to rotate. The gear 140, in conjunction with the gear ring 313, controls the third limiting plate 310 to rotate. The second limiting plate 210 rotates synchronously to facilitate placing the workpiece at different positions on the second limiting plate 210. After the sealing door 150 closes the inner cavity of the baking oven 100, the motor 321 controls the reciprocating screw 320 to rotate. The screw nut 211, in conjunction with the reciprocating screw 320, controls the second limiting plate 210 to move upward, so that the insertion rod 163 is inserted into the cavity of the positioning hole 154 simultaneously, thereby locking the sealing door 150. By raising and lowering the second limiting plate 210, the distance between the workpiece and the heater 130 can be adjusted, thereby controlling the baking temperature and baking effect. By properly adjusting the position of the workpiece, quality problems caused by excessively high or low temperatures can be avoided, ensuring the best baking effect. During the baking process, the gear 140, in conjunction with the gear ring 313, controls the rotation of the limit plate 210, so that the workpiece revolves synchronously around the reciprocating screw 320. This ensures that all parts of the workpiece are heated evenly, avoiding local overheating or undercooling.
[0038] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
