In the above scheme, it should be noted that the heater 12 is model LH-KJS and is an existing product. The specific structure and heating principle of the heater 12 are all existing publicly available technologies, and will not be described in detail here.

[0018] In this embodiment, the support frame 11 is used to stably support and install the heating box 1, and the heater 12 is used to heat the inside of the heating box 1. First, the fixed seat 13 is installed on the bottom inner wall of the heating box 1. Then, the rolling balls 14 are placed in the ball groove above the fixed seat 13 in sequence, and the cover 15 is fastened to the upper surface of the fixed seat 13 from top to bottom. At the same time, the upper part of the rolling ball 14 protrudes above the cover 15, so that the ADI product can be transported by rotating the rolling ball 14.

[0019] Please see Figure 1 and Figure 2 A material slide platform 2 is connected to one side of the heating box 1, and a storage platform 3 is connected to the other side of the heating box 1. A collection box 4 is provided below the material slide platform 2. Foot 41 is fixedly provided on both sides of the bottom of the collection box 4, and handle 42 is provided on both sides of the outer wall of the collection box 4.

[0020] In this embodiment, when heat-treating the ADI product, it is placed on the storage platform 3 and transported into the heating chamber 1 by the cooperation of the push rod 9 and the feeding door 7. After the heat treatment is completed, the push rod 9 enters the heating chamber 1 and pushes the treated ADI product into the sliding platform 2 and into the collection box 4 for storage.

[0021] Please see Figure 1 and Figure 3 A material handling door 5 is provided on one side of the heating box 1. Guide ribs 51 are provided on both sides of the material handling door 5. The material handling door 5 is slidably connected inside the guide ribs 51. One side of the guide ribs 51 is fixedly installed on the outer wall of the heating box 1.

[0022] In this embodiment, the guide rib 51 is used to guide and limit the lifting and lowering movement of the material picking door 5. The guide rib 51 is bolted to the side wall of the heating box 1.

[0023] Please see Figure 1 and Figure 3The top of the heating box 1 is provided with a drive mechanism 6 for opening and closing the material handling door 5. The drive mechanism 6 includes a drive motor 61 fixed on the outer wall of the top of the heating box 1, and a gear set 62 is driven and connected to the output shaft of the drive motor 61. A drive shaft 63 is driven and connected to one side of the gear set 62. Both ends of the drive shaft 63 are provided with drive gears 64. An outer cover 65 is fixed on the top of the heating box 1 and is provided on the outside of the drive mechanism 6. The outer cover 65 plays a protective role for the drive mechanism 6. A toothed plate 52 is symmetrically distributed on one side of the material handling door 5 and the toothed plate 52 is meshed with the drive gear 64.

[0024] In this embodiment, starting the drive motor 61 can drive the gear set 62, the transmission shaft 63 and the drive gear 64 to rotate, thereby using the drive gear 64 to drive the material picking door 5 to rise. The back of the material picking door 5 is provided with toothed structures that mesh with the drive gear 64, so that the rotational motion of the drive gear 64 is converted into the lifting motion of the material picking door 5.

[0025] Please see Figure 2 and Figure 6 On the other side of the heating box 1, there is a feeding door 7. The feeding door 7 is composed of a fixed plate 71 connected to the heating box 1, a movable outer plate 72, a movable middle plate 73 and a movable core plate 74 embedded inside the fixed plate 71. The fixed plate 71, the movable outer plate 72, the movable middle plate 73 and the movable core plate 74 are installed sequentially from the outside to the inside.

[0026] In this embodiment, the opening and closing of the corresponding feed door 7 according to different specifications of ADI products can effectively reduce heat loss. The movable outer plate 72, movable middle plate 73 and movable core plate 74 are used in combination to realize the opening and closing of different areas.

[0027] Please see Figure 6 and Figure 7Several locking components 8 are provided on the fixed plate 71, the movable outer plate 72, the movable middle plate 73, and the movable core plate 74. Each locking component 8 includes an adjacent connecting seat 1 81 and a connecting seat 2 82. Insert rods 83 are installed inside the connecting seat 1 81 and the connecting seat 2 82. Several sleeves 84 are provided on the outer wall of the feed door / window 7. The insert rods 83 are slidably inserted into the sleeves 84. A locking bolt 85 penetrating to the interior is provided on one side of the outer wall of the sleeve 84. It should be noted that the connecting seat 1 81 and the connecting seat 2 82 are respectively fixedly installed on the fixed plate 71, the movable outer plate 72, and the movable middle plate. The outer surfaces of 73 and the movable core plate 74 are connected by the extension and retraction of the insertion rod 83 inside the sleeve 84, so that the insertion rod 83 is inserted into the interior of the first connecting seat 81 and the second connecting seat 82, thereby achieving the connection and fixation of the two. The locking bolt 85 is used to fix the relative position between the insertion rod 83 and the sleeve 84, ensuring the stability of the locking assembly 8. A sliding groove 87 is provided on one side of the outer wall of the sleeve 84. A lever 86 with one end fixed to the outer wall of the insertion rod 83 is slidably connected inside the sliding groove 87. The lever 86 can slide inside the sliding groove 87, thereby driving the insertion rod 83 to move inside the sleeve 84.

[0028] In this embodiment, the locking assembly 8 can be used to fix the connection between the fixed plate 71, the movable outer plate 72, the movable middle plate 73, and the movable core plate 74, thereby allowing the selection of different sizes of feed doors and windows 7 to be opened. For example, when the movable outer plate 72 needs to be opened, the locking assemblies 8 on the movable outer plate 72, the movable middle plate 73, and the movable core plate 74 are all fixedly connected, while the locking assembly 8 between the movable outer plate 72 and the fixed plate 71 is released. This allows the push rod 9 to drive the movable outer plate 72, the movable middle plate 73, and the movable core plate 74 to open and close together. Since the specifications and models of ADI products are all mass-produced, it is necessary to set feed doors and windows 7 of different sizes to avoid heat loss inside the heating box 1 when all feed doors and windows 7 are opened.

[0029] Please see Figure 2 and Figure 6 A push rod 9 is fixedly installed on the top outer wall of the storage platform 3. The push rod 9 is used to drive the material inlet door 7 to move and open or close.

[0030] In this embodiment, the push rod 9 can be an electric telescopic rod or a multi-section telescopic rod structure. The push rod 9 can be used to open the feeding door 7 and push the ADI products into the heating box 1, realizing feeding and unloading operations, which brings great convenience to people's heat treatment of ADI products.

[0031] The working principle and usage process of this utility model are as follows: First, the worker starts the push rod 9 to move. According to the specifications of different ADI products, the corresponding area of ​​the movable outer panel 72, movable middle panel 73 and movable core panel 74 are selected. The combination and single use of the movable outer panel 72, movable middle panel 73 and movable core panel 74 can be realized through the locking component 8. If the ADI product is small, only the push rod 9 needs to drive the movable core panel 74 to move and open and close. At this time, the worker releases the locking component 8 between the movable core panel 74 and the movable middle panel 73. Since the fixed plate 71, movable outer panel 72 and movable middle panel 73 are all connected through the locking component 8, when the push rod 9 drives the movable core panel 74 to move, the other door panels do not move. Next, after the movable core plate 74 is opened, the worker places the ADI product on the storage platform 3 during heat treatment. The push rod 9 drives the movable core plate 74 to push the ADI product above the rolling ball 14 inside the heating chamber 1. It should be noted that the movable core plate 74 can move back and forth inside and outside the heating chamber 1, so that the ADI product can be placed directly above the fixed seat 13, which is more conducive to the heat treatment of the ADI product. Finally, after the ADI product has undergone heat treatment, the material handling door 5 is opened using the drive mechanism 6. The number of rotations of the drive mechanism 6 determines the size of the opening at the bottom of the material handling door 5, which is also adjusted according to the specifications of the ADI product. Specifically, the drive motor 61 is started, which drives the gear set 62, the transmission shaft 63 and the drive gear 64 to rotate. The drive gear 64 then drives the material handling door 5 to rise, and the push rod 9 drives the moving core plate 74 to push the ADI product into the slide table 2 and then into the collection box 4, thereby realizing the feeding and picking operations.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
