An adjustment box is fixedly bolted to the end face of the two support columns away from the fixed base. The adjustment box has a rotating mechanism inside, and two push plates are symmetrically arranged between the two adjustment boxes. However, in this device, the support columns and their connected devices are completely fixed, requiring precise alignment with the inlet of the heat treatment furnace during installation. This may lead to frequent overall movement of the device during installation, affecting the convenience of the installation process. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of the existing technology by providing a material conveying structure for a metal heat treatment furnace that can be connected to the inlet of the heat treatment furnace, thereby reducing the accuracy of the installation of this device and making the installation process more convenient and labor-saving.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A material conveying structure for a metal heat treatment furnace includes a main support frame, a drive slider, a movable support platform, a conveyor belt, a main conveyor belt support roller, an auxiliary support roller, a conveyor drive motor, an adjusting screw, a main drive rod, and a screw drive motor. The main support frame has a movable platform connecting groove inside, which is adapted to the movable support platform and connected to it. The movable support platform slides inside the movable platform connecting groove. The movable support platform has auxiliary support roller connecting grooves and main support roller connecting grooves on its side. An array of multiple sets of auxiliary support roller connecting grooves is located in the center. Two sets of main support roller connecting grooves are distributed on both sides of the array of auxiliary support roller connecting grooves. The auxiliary support rollers are rotatably connected to the auxiliary support roller connecting grooves. The main conveyor belt support rollers are rotatably connected to the main support roller connecting grooves. The conveyor belt is sleeved on the outside of the main conveyor belt support rollers. The auxiliary support rollers are pressed against the bottom of the upper half of the conveyor belt. The main conveyor belt support rollers have a drive rod connecting groove inside.

[0006] The moving platform has main support roller mounting slots on both sides of the connecting slot. The position of the main support roller mounting slot corresponds to the position of the main support roller connecting slot. The main drive rod is rotatably connected to the main support roller mounting slot. The main drive rod is adapted to the drive rod connecting slot and is connected to the drive rod connecting slot. The main drive rod slides inside the drive rod connecting slot. The side of the main support roller mounting slot has a conveyor motor mounting platform. The conveyor drive motor is inserted into the conveyor motor mounting platform and fixed. The transmission shaft of the conveyor drive motor is fixedly connected to the main drive rod.

Beneficial effects

[0008] 1. When installing this material conveying device for a metal heat treatment furnace, the device is connected to the inlet of the heat treatment furnace. If there is a partial lateral error during the connection process, the screw drive motor is started. The screw drive motor drives the slider to move by adjusting the screw drive, so that the moving support platform moves laterally inside the moving platform connecting groove. This allows the device to connect to the inlet of the heat treatment furnace, thereby reducing the installation accuracy of the device and making the installation process more convenient and labor-saving.

[0009] 2. In this utility model, multiple sets of drive plate mounting slots are connected to multiple sets of drive plates simultaneously, so that when the drive slider drives the moving support platform to move, the moving support platform is subjected to force at multiple points at the same time, making the force on the moving support platform more uniform and the movement more stable.

[0010] 3. The adjusting screw and the screw connecting groove of this utility model adopt a threaded connection. The threaded connection has good self-locking properties, so that after the driving slider drives the moving support table to adjust, the moving support table is less likely to be moved by external influences, thus ensuring the stability of the heat treatment material conveying process.
