[0041] (Example 1)

[0042] See Figure 1 A belt clamping and conveying mechanism includes two symmetrically arranged frames 1, each frame 1 being equipped with a belt assembly; the belt assembly includes a clamping belt 2, a drive device 3, a drive pulley 4, and a driven pulley 5, the drive pulley 4 and the driven pulley 5 being respectively installed at both ends of the frame 1, the clamping belt 2 being wrapped around the drive pulley 4 and the driven pulley 5, the drive device 3 being connected to the drive pulley 4 and driving the clamping belt 2 to move; the clamping belts 2 corresponding to the two frames 1 clamp and convey materials from both sides, and the tension of the clamping belt 2 is adjustable.

[0043] Furthermore, the tension of the clamping belt 2 is achieved by adjusting the installation position of the driven wheel 5. A tension adjustment device 6 is connected between the frame 1 and the driven wheel 5. The tension adjustment device 6 includes a rocker arm 6-1, which is rotatably mounted on the frame 1 via a rotating shaft 6-2. The driven wheel 5 is mounted on the rocker arm 6-1 and spaced apart from the rotating shaft 6-2.

[0044] This embodiment achieves flexible adjustment of the driven wheel position by rotatably connecting the swing arm to the frame and setting a rotation adjustment switch. This helps to ensure the belt tension, facilitates belt replacement by operators, saves replacement time, and makes the overall adaptability of the conveyor better.

[0045] Furthermore, see Figure 3 A first handle 6-3 is fixed to the rotating shaft 6-2, and a first washer 6-4 is fitted onto the rotating shaft 6-2. The first washer 6-4 is located between the swing arm 6-1 and the first handle 6-3. The rotating shaft 6-2 is a screw. When the rotating shaft 6-2 is not tightened, the swing arm 6-1 can rotate around the rotating shaft 6-2; when the rotating shaft 6-2 is tightened, the swing arm 6-1 is fixed to the frame. The first handle 6-3 facilitates manual adjustment, and the first washer 6-4 prevents wear between the swing arm and the first handle, extending the service life of the equipment.

[0046] Further details can be found here. Figure 3The swing arm 6-1 is also equipped with a limiting rod 6-5 and an arc-shaped through-channel 6-8 centered on the pivot 6-2. The limiting rod 6-5 passes through the arc-shaped through-channel 6-8 and connects to the frame 1. A second handle 6-6 is fixed to the upper end of the limiting rod 6-5. A second washer 6-7 is fitted onto the limiting rod 6-5, located between the swing arm 6-1 and the second handle 6-6. The limiting rod 6-5 is a screw. The second handle and the second washer further increase the stability of the swing arm when it is fixed.

[0047] Furthermore, the arc-shaped channel 6-8 has at least one closed end along the arc direction. When the limiting rod 6-5 is located at the closed end of the arc-shaped channel 6-8, the clamping belt 2 is in a taut state. This makes the belt more stable when the clamping belt 2 is in the working state, preventing the belt from loosening due to shaking.

[0048] Further details can be found here. Figure 1 The left and right frames 1 are symmetrically equipped with guardrails 7. The guardrails 7 are equipped with lifting adjustment devices 7-1 and left and right adjustment devices 7-2. The guardrails with adjustable height and width installed above the left and right frames provide additional safety for operation and also adapt to the needs of materials of different sizes, thus improving the applicability of the equipment. The lifting adjustment device 7-1 and the left and right adjustment device 7-2 are both existing technologies.

[0049] Further details can be found here. Figure 4 and Figure 5 Each of the left and right machine frames 1 is symmetrically equipped with a machine frame adjustment device 8. The machine frame adjustment device 8 includes a lead screw mounting seat 8-1, an adjusting lead screw 8-2 rotatably mounted on the lead screw mounting seat 8-1, an adjusting nut 8-3 sleeved on the adjusting lead screw 8-2, and a handwheel 8-4 fixed to one end of the adjusting lead screw 8-1. The adjusting lead screw 8-2 is horizontally arranged along the left and right direction of the machine frame 1, and the adjusting nut 8-3 is fixedly connected to the corresponding machine frame 1. The corresponding adjusting lead screws 8-1 of the left and right machine frames 1 are connected by a coupling 8-5.

[0050] The frame adjustment device 8 also includes a connecting seat 8-6 and a sliding rod 8-7. The connecting seat 8-6 is fixedly connected to the frame 1 and the adjusting nut 8-3 respectively. The sliding rod 8-7 is parallel to the adjusting screw 8-1 and passes through the connecting seat 8-6, and is fixedly connected to the screw mounting seat 8-1. The connecting seat 8-6 and the sliding rod 8-7 are slidably connected. There are two sliding rods 8-7, located on both sides of the adjusting screw 8-1. Multiple frame adjustment devices 8 can be selected according to the length of the frame 1.

[0051] The use of couplings allows the adjusting screws to move synchronously in opposite directions or in the same direction, and keeps the centerline of the left and right frames constant, facilitating connection with the upper and lower conveying devices; the connecting seat and sliding rod improve the stability and reliability of the equipment operation.

[0052] (Example 2)

[0053] Example 2 is basically the same as Example 1, except that the arc-shaped channel 6-8 can be a groove, and one end of the limiting rod 6-5 is fixed on the frame 1, while the other end is slidably set in the groove.

[0054] (Example 3)

[0055] Example 3 is basically the same as Example 1, except that the tension adjustment device 6 can also be set between the drive wheel 4 and the frame 1. The tension of the belt 2 can be adjusted by adjusting the installation position of the drive wheel 4 relative to the frame 1.
