[0040] Please also read Figure 1 and Figure 3 The lifting type curing box 100 provided in the embodiment of the present invention includes a box body 10, a curing device (not shown), a box door 20, a movable door structure 30 and a lifting mechanism 40, and is applied to the technical field of curing equipment to solve the technical problem in the prior art that heat is easily lost during the loading and unloading process of the oven, resulting in low work efficiency and high cost.

[0041] Specifically, a feed window 21 and a discharge window 22 are provided at intervals on one side of the box body 10, and both the feed window 21 and the discharge window 22 are connected to the inner cavity of the box body 10. The feed window 21 is used for the external material tray 200 to enter the box body 10, and the discharge window 22 is used for the material tray 200 to move out of the box body 10. The curing device is arranged in the inner cavity of the box body 10, and the curing device is used to cure the product on the material tray 200 in the inner cavity of the box body 10. The movable door structure 30 includes a first door component 31 and a second door component 32, which are respectively movably arranged at the feed window 21 and the discharge window 22. The first door component 31 can open or close the feed window 21, and the second door component 32 can open or close the discharge window 22. When the external material tray 200 needs to enter the inner cavity of the box body 10, the first door component 31 opens the feed window 21 and closes the feed window 21 after the feeding is completed. When the product on the material tray 200 in the inner cavity of the box body 10 is cured, the second door component 32 opens the discharge window 22 and closes the discharge window 22 after the discharge is completed. Among them, the discharge window 22 and the feed window 21 can only be moved in and out by one material tray 200 at a time. The lifting mechanism 40 is fixed on the box body 10 and at least partially movably disposed in the inner cavity of the box body 10. The lifting mechanism 40 can simultaneously support multiple vertically arranged trays 200, that is, support multi-layer trays 200. The lifting mechanism 40 can receive the trays 200 one by one from the feeding window 21, and drive the multi-layer trays 200 to rise or fall layer by layer in the inner cavity of the box body 10 according to the preset time and preset distance, so as to realize driving the trays 200 one by one to the discharge window 22. Among them, the lifting mechanism 40 is vertically arranged and penetrates the entire box body 10 and is at least partially disposed in the inner cavity of the box body 10, and the lifting mechanism 40 is centrally disposed in the inner cavity of the box body 10.

[0042] In the embodiment of the present invention, a first door assembly 31 and a second door assembly 32 are provided on one side of the box body 10, which can respectively open or close the feed window 21 and the discharge window 22, and the lifting mechanism 40 is at least partially movably provided in the inner cavity of the box body 10. The lifting mechanism 40 can receive the material trays 200 one by one from the feed window 21, and drive all the material trays 200 in the inner cavity of the box body 10 to move from the feed window 21 to the discharge window 22 during the curing process of the material trays 200 and complete the curing operation. At the same time, the external equipment can be respectively The feed window 21 and the discharge window 22 are used to put in and take out the tray 200 one by one, which is convenient for loading and unloading the tray 200, and avoids the heat loss when opening the door 20 of the curing box 100 to load and unload the tray 200, so that the temperature inside the box 10 is uniform, and there is no need to perform heating operation, which reduces costs, and can speed up the curing speed of the product and improve work efficiency; and it can also avoid the situation that when the door 20 is opened to take out the tray 200, the temperature of the product on the tray 200 drops during transportation, resulting in the inability to meet the product curing process. In addition, it can also avoid the situation that the dust on the human body causes the product to be dirty when the door 20 is opened. On the other hand, the temperature inside the box 10 is uniform, and the tray 200 does not need to be heated again when entering the inner cavity of the box 10. After entering the inner cavity of the box 10, the tray 200 can be cured once, and it is not necessary to heat up before curing for pre-curing, thereby improving the curing efficiency of the product in the tray 200.

[0043] Specifically, the lifting mechanism 40 is used to realize the lifting and lowering movement of the material tray 200. The material tray 200 enters the lifting mechanism 40 from the feed window 21 and moves out from the discharge window 22. In this embodiment, the feed window 21 and the discharge window 22 are arranged at intervals and are respectively located at the upper and lower ends of one side of the box body 10. The feed window 21 is set below the discharge window 22, that is, the lifting mechanism 40 is mainly used to move the material tray 200 entering at the feed window 21 to the discharge window 22. The following embodiments are described with the feed window 21 located below the discharge window 22. Of course, in the embodiments of the present invention, the specific positions of the feed window 21 and the discharge window 22, and the lifting mechanism 40 used to realize the rise or fall of the material tray 200 are not uniquely limited.

[0044] In this embodiment, the specific operation of the lifting curing box 100 is as follows: the first door assembly 31 and the second door assembly 32 close the feed window 21 and the discharge window 22 respectively, so that the inner cavity of the box body 10 forms a relatively closed environment, prevents internal heat loss, and achieves a heat preservation effect. When feeding is required, the first door assembly 31 moves to open the feed window 21, and the external transport mechanism extends the material tray 200 from the feed window 21 into the inner cavity of the box body 10, so that the material tray 200 enters the lifting mechanism 40, and the external transport mechanism exits the box body 10, and the first door assembly 31 moves to close the feed window 21, and the lifting mechanism 40 drives all the material trays 200 to rise a certain distance at a preset time, and the external transport mechanism can complete the next feeding operation. The feeding operation here is the same as the above-mentioned feeding operation, and the lifting mechanism 40 will raise all the material trays 200 by a certain distance at the next preset time, so as to realize the layer-by-layer rise of the material trays 200. When the tray 200 initially transported into the lifting mechanism 40 gradually rises to the top of the lifting mechanism 40 according to the preset time, that is, the tray 200 rises to the discharge window 22, the total time taken for the tray 200 to rise is the total time for the product on the tray 200 to heat up and solidify in the inner cavity of the box 10, at which time the products on the tray 200 complete the solidification operation one by one, the second door assembly 32 moves to open the discharge window 22, and the external transport mechanism takes out the tray 200 from the discharge window 22 to allow the product to proceed to the next process, and the external transport mechanism can also take out the next tray 200 from the discharge window 22 at the next preset time, and so on, and finally the trays 200 entering from the feed window 21 can all rise to the top of the first support structure 41, that is, rise one by one to the discharge window 22. Among them, the lifting mechanism 40 can receive the trays 200 one by one from the feed window 21, and take out the trays 200 one by one at the discharge port. Therefore, when the material tray 200 enters or moves out of the box 10, there is no need to open the door 20 of the curing box 100 to avoid heat loss in the inner cavity of the box 10, and when the material tray 200 gradually rises to the discharge window 22, the product on the material tray 200 has just completed curing.

[0045] Specifically, in this embodiment, the lifting type curing box 100 also includes a controller (not shown), which is electrically connected to the lifting mechanism 40, the first door assembly 31 and the second door assembly 32, respectively, and is used to control the first door assembly 31 and the second door assembly 32 to open or close the feed window 21 and the discharge window 22, respectively, and also controls the lifting mechanism 40 to rise or fall according to a preset time and a preset distance.

[0046] In this embodiment, the feed window 21 and the discharge window 22 can be arranged on the side wall of one side of the box body 10. Of course, the feed window 21 and the discharge window 22 can be arranged in multiple pairs, and the multiple pairs of feed windows 21 and the discharge window 22 are respectively arranged on different side walls of the box body 10, so that the loading, unloading and curing operations of multiple trays 200 can be realized at the same time.

[0047] Preferably, in this embodiment, a door 20 may be hinged on one side of the box body 10, and the door 20 is used to open or close the box body 10, which is convenient for maintenance of the box body 10. The feed window 21 and the discharge window 22 are arranged at intervals on the door 20 to avoid opening the door 20 when loading and unloading the material tray 200.

[0048] Specifically, in this embodiment, only one box door 20 is provided, and the box door 20 is provided on one side of the box body 10. Of course, the box door 20 here can be provided in plurality, and the plurality of box doors 20 are respectively provided on different sides of the box body 10, and the box doors 20 on multiple sides can simultaneously realize the loading, unloading and curing operations of the material tray 200, thereby improving production efficiency.

[0049] Specifically, in this embodiment, the curing device includes a heating device, an air circulation device, a temperature control device and a heat preservation device, which are not described one by one here.

[0050] Specifically, see Figure 2 In this embodiment, an air vent 14 is provided on the box body 10 for ventilating the inner cavity of the box body 10 .

[0051] Specifically, see Figure 2 A plurality of fixed columns 15 are provided at the bottom of the box 10 for supporting the box 10, and a plurality of universal wheels 12 are provided beside the fixed columns 15 for moving the entire box 10. The number of the fixed columns 15 and the universal wheels 12 is four, but not limited thereto.

[0052] Specifically, in this embodiment, the provision of the box door 20 facilitates the adjustment of temperature uniformity in the inner cavity of the box body 10, the installation of the structure, and internal maintenance work. An insulation layer is provided on the box door 20 to prevent the temperature outside the box door 20 from being too high and causing burns to the user.

[0053] Please also refer to Figure 1 and Figure 3In this embodiment, the lifting mechanism 40 includes a first support structure 41, a second support structure 42 and a driving structure 43. The first support structure 41 vertically penetrates the entire box body 10 and is at least partially movably disposed in the inner cavity of the box body 10. The first support structure 41 can be moved to support or release the material tray 200. The second support structure 42 vertically penetrates the entire box body 10 and is at least partially movably disposed in the inner cavity of the box body 10. The second support structure 42 can be moved beside the first support structure 41 to support or release the material tray 200, so that the first support structure 41 and the second support structure 42 can support the material tray 200 alternately. The driving structure 43 is connected to the second support structure 42 and can drive the second support structure 42 to move up and down according to a preset time and a preset distance, so that the second support structure 42 drives the multiple material trays 200 supported on the first support structure 41 to move up and down, thereby realizing the lifting and lowering of the material trays 200 on the first support structure 41. The overall structure of the lifting mechanism 40 is relatively simple, and the curing operation is also very simple. The preset time and preset distance of the lifting activity of the second bracket structure 42 can be adjusted according to needs, and the versatility is relatively wide.

[0054] Specifically, in this embodiment, when the external transport mechanism moves the material tray 200 from the feed window 21 into the inner cavity of the box body 10, the first support structure 41 moves to support the material tray 200 first, and at a predetermined time, the second support structure 42 moves to support the material tray 200 on the first support structure 41. At this time, the first support structure 41 moves to release the material tray 200 and realizes the avoidance effect to avoid the active position of the second support structure 42 and the material tray 200, then the driving structure 43 drives the second support structure 42 to rise by a preset distance to realize the material tray 200 rising by a preset distance, and the controller controls the first support structure 41 to move to support the material tray 200 again, and finally the second support structure 42 moves to release the material tray 200, and moves downward under the drive of the driving structure 43 to reset, so that the material tray 200 rises on the first support structure 41. Among them, when the first support structure 41 supports multiple material trays 200, the second support structure 42 can support multiple material trays 200 at one time to realize their rising operation. The driving structure 43 can drive the second support structure 42 to drive all the trays 200 on the first support structure 41 to rise layer by layer until the tray 200 initially entering from the feed window 21 rises to the discharge window 22, and the product on the tray 200 completes the solidification process.

[0055] Please also refer to Figure 3 and Figure 4 In this embodiment, the first support structure 41 includes a first driving assembly 411, a plurality of vertically arranged first support rods 412, and a plurality of first supporting arms 413 vertically arranged on the first support rods 412.

[0056] Specifically, in this embodiment, the first support rod 412 is rotatably disposed on the box body 10, the first support rod 412 vertically penetrates the entire box body 10 and is at least partially rotatably disposed in the inner cavity of the box body 10, and multiple first support rods 412 are arranged at intervals and enclosed to form a first support frame (not shown). Multiple first support arms 413 are arranged vertically and equidistantly on the first support rod 412, and a first support arm 413 of the same height on multiple first support rods 412 can be used to jointly support the material tray 200. At this time, the material tray 200 is supported on the first support frame, and multiple first support arms 413 of different heights on the first support rod 412 can support multiple layers of material trays 200, thereby achieving the support work of multiple layers of material trays 200. The first driving assembly 411 is connected to the first supporting rod 412 and can drive the first supporting rod 412 to rotate. When the material tray 200 needs to be raised, the second bracket structure 42 can be moved to support the material tray 200. The first driving assembly 411 drives the first supporting rod 412 to rotate so that the first supporting arm 413 rotates around the first supporting rod 412 so that the first supporting arm 413 is disengaged from the bottom of the material tray 200. At this time, the first supporting arm 413 rotates to the outside of the material tray 200 to release the material tray 200, and also achieves the avoidance effect.
