[0020] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:
[0021] According to the instruction manual Figure 1-3It can be known that when the utility model is working and the heating platform or mold needs to be repaired or replaced, the conveying chain mechanism 1 is started. Since the box door 14 is vertically slidably connected to the front end surface of the machine body 12 through the first sliding limiter 11, the chain in the conveying chain mechanism 1 can drive the connecting rod 2 and the box door 14 to move upward, open the box door 14, and the personnel can operate. During production, close the box door 14, start the motor 7 with dual output ends on the material door 5, and the dual output ends of the motor 7 rotate to drive the rotating shaft 8 to rotate. The rotating shaft 8 ensures the stability of rotation through the limit plate 9 and the bearing. A gear 10 is arranged on the outside of the rotating shaft 8, and a rack 13 is arranged vertically on the front side wall of the box door 14 corresponding to the position of the gear 10. The gear 10 is meshed with the rack 13. Since the material door 5 is vertically slidably connected with the front side wall of the box door 14 through the second sliding limiter 15, the rotation of the rotating shaft 8 can make the material door 5 move upward, thereby opening the material port 6 opened on the material door 5. According to the height of the personnel and the shape and size of the part 18, the material box is opened upward to a height that is convenient for the personnel to operate, and the part 18 is placed on the lower mold 19. After the adjustment is completed, the motor 7 is started again, the material door 5 is closed, and the thermoforming process is carried out. When taking materials, only the material door 5 needs to be opened, the part 18 is taken out, and the next part 18 is placed, which reduces the heat loss in the non-operating area and saves energy.
[0022] In this embodiment, a heat insulation layer can be set between the motor 7 and the material door 5 in the utility model to prevent the motor 7 from being in a high temperature environment; the first sliding limiter and the second sliding limiter 15 can adopt the existing slide rail assembly to ensure the stability of the box door 14 and the material box when moving up and down.
[0023] Among them, a slider 20 is rotatably provided at the outer end of the rotating shaft 8, and a fixed plate 3 is vertically provided at a position near the edge of the side wall of the box door 14. The slider 20 is slidably connected to a slide groove vertically opened on the side wall of the fixed plate 3, thereby increasing the stability of the rotating shaft 8, the stability of the engagement between the gear 10 and the rack 13, and the stability of the movement of the material door 5.
[0024] Among them, protective covers are arranged outside the motor 7, the rotating shaft 8 and the gear 10 to ensure the working stability of the motor 7, the gear 10 and the rack 13 and prevent people from touching them.
[0025] In addition, the inner wall edges of the box door 14 and the inner wall edges of the material door 5 are provided with heat insulation cotton 16 to improve the sealing and reduce the heat loss during work. The material door 5 is provided with a visual window made of high temperature resistant glass to facilitate personnel to observe the internal working conditions.
