[0033] Referring to Figure 1 , on both sides of the conveyor belt 21, side guide plates 3 are installed. In the middle position above the conveyor belt 21, an intermediate guide plate 4 is installed. On the support frame 2, a connecting frame 22 located above the conveyor belt 21 is installed, and the connecting frame 22 is fixedly connected to the intermediate guide plate 4. Through the connecting frame 22, it is convenient to install the intermediate guide plate 4 above the conveyor belt 21. Two conveying tracks are formed by the intermediate guide plate 4 and the side guide plates 3 on both sides of the support frame 2, improving the workpiece conveying efficiency.

[0034] Referring to Figure 1 , on the side of the two side guide plates 3 facing each other and close to the input end of the conveyor belt 21, a first guide surface 31 is provided. On both sides of the intermediate guide plate 4 close to the input end of the conveyor belt 21, second guide surfaces 41 are provided. The distance between the first guide surface 31 and the second guide surface 41 is greater than the distance at the middle position between the side guide plates 3 and the intermediate guide plate 4, so as to facilitate placing the workpiece on the conveyor belt 21 for conveying.

[0035] Referring to Figure 1 and Figure 2 , on the workbench 1, an adjustment assembly 5 for adjusting the distance between the two side guide plates 3 is provided. The number of the adjustment assemblies 5 is multiple and even. The adjustment assemblies 5 are arranged in two columns on both sides of the workbench 1 respectively. The number of the two columns of adjustment assemblies 5 is the same and they correspond one by one. The adjustment assembly 5 includes a connecting plate 51, a connecting base 52 and a sliding guide rail 53. On the side of the two side guide plates 3 away from each other, connecting plates 51 are installed. The connecting base 52 is installed at the bottom of the connecting plate 51. The sliding guide rail 53 is installed on the workbench 1 along the width direction of the workbench 1. The sliding guide rail 53 is located below the support frame 2. The connecting base 52 is installed on the sliding guide rail 53 and is slidably connected to the sliding guide rail 53. By moving the connecting base 52 along the sliding guide rail 53, the connecting plate 51 drives the side guide plate 3 to move, thereby adjusting the position of the side guide plate 3.

[0036] Referring to Figure 1 , Figure 2 and Figure 3, an adjusting plate 6 is installed at the middle position between the support frame 2 and the workbench 1 along the length direction of the workbench 1. A longitudinal guide rail 12 is installed on the workbench 1 along the length direction of the workbench 1. The adjusting plate 6 is installed on the longitudinal guide rail 12 and is slidably connected to the longitudinal guide rail 12. The longitudinal guide rail 12 provides limit guidance for the movement of the adjusting plate 6, improving the stability of the movement of the adjusting plate 6.

The output shaft of the driving motor 71 is coaxially and fixedly connected to the adjusting lead screw. Starting the driving motor 71, the rotation of the adjusting lead screw drives the adjusting nut seat 72 to move along the length direction of the workbench 1, thereby driving the adjusting plate 6 to move along the length direction of the workbench 1. The adjusting connecting rod 61 pulls the two connecting bases 52 on both sides of the adjusting plate 6 to approach or move away from each other, thereby adjusting the distance between the two side guide plates 3, and at the same time, synchronously and equally adjusting the distance between the two side guide plates and the middle guide plate 4. Adjusting the distance between the middle guide plate 4 and the side guide plates 3 according to the volume of the workpiece improves the stability of the workpiece conveying process and facilitates the conveying of workpieces of different sizes.

[0037] Refer to Figure 2 , a tension spring 8 is arranged between the two connecting bases 52 at the end far from the adjusting nut seat 72. During the movement of the adjusting nut seat 72, during the movement of the adjusting plate 6, through the tension spring 8, the adjusting accuracy and adjusting stability are improved.

[0038] Refer to Figure 1 , protective frames 9 are arranged on the workbench 1 on both sides of the support frame 2. The two side guide plates 3 on both sides are protected by the protective frames 9 to prevent the side guide plates 3 from moving outside the conveyor belt 21.

[0039] The implementation principle of a double-track adjusting device in an embodiment of the present application is: starting the driving motor 71, the rotation of the adjusting lead screw drives the adjusting nut seat 72 to move along the length direction of the workbench 1, thereby driving the adjusting plate 6 to move along the length direction of the workbench 1. The adjusting connecting rod 61 pulls the two connecting bases 52 on both sides of the adjusting plate 6 to approach or move away from each other, thereby adjusting the distance between the two side guide plates 3, and at the same time, synchronously and equally adjusting the distance between the two side guide plates and the middle guide plate 4. Adjusting the distance between the middle guide plate 4 and the side guide plates 3 according to the volume of the workpiece improves the stability of the workpiece conveying process and facilitates the conveying of workpieces of different sizes.
