Description

Technical Field

[0002] With the increasing support from the government for new energy development projects, the photovoltaic solar power generation industry has seen a booming development. This has led to a surge in the business volume of a series of upstream related industries. As an indispensable contact consumable in the production of photovoltaic solar panels, the use of quartz products has increased rapidly, putting pressure on the production of upstream quartz product suppliers.

[0003] In the prior art, after searching Chinese patent number CN220201772U, a large-diameter tube cutting machine for quartz tube processing is disclosed; it includes a mounting frame and a fixed frame connected to one side of the mounting frame, a roller support mechanism is connected to the mounting frame, and a lifting cutting mechanism is provided on the fixed frame; it also includes a sliding assembly and a linear adjustment assembly, the cutting mechanism is connected to the fixed frame through the sliding assembly, the linear adjustment assembly is connected to the cutting mechanism, and is suitable for driving the cutting mechanism to move horizontally perpendicular to the direction of the mounting frame; the linear adjustment assembly includes a longitudinal screw rod, a hanging plate, a nut seat and a mounting seat, the nut seat is spirally connected to the longitudinal screw rod, the inner hole of the mounting seat is rotatably connected to the longitudinal screw rod, the mounting seat is connected to the hanging plate, the hanging plate is connected to the mounting frame, the nut seat is connected to the cutting mechanism, and the outer end of the longitudinal screw rod is connected to a round handle. The utility model has a reasonable structure, enhances the cutting effect of large-diameter quartz tubes, and improves production efficiency.

[0004] When cutting the quartz tube, since the quartz tube is long, it needs to be cut to a fixed length, but the quartz tube with a large diameter is heavy as a whole, so it is more laborious to move the quartz tube. The above scheme places the quartz tube with a large diameter on the top of nylon wheel one and nylon wheel two, thereby driving the quartz tube to rotate, so that the cutting blade assembly can cut the quartz tube, but the cutting blade assembly cannot move laterally, and then when a section of quartz tube is cut, it is necessary to push the quartz tube to move, so as to facilitate subsequent cutting, but the friction between the surface of the quartz tube and the nylon wheel one and nylon wheel two is large, so it is more laborious to push the quartz tube.

[0034] The first U-shaped frame 201 is provided with multiple groups in a linear array, and when the first driving component 3 drives the rotating shaft 4 to move, it can drive the sliding seat 203 arranged on its outer surface to move. When the sliding seat 203 moves, it slides on the outer surface of the sliding rod 202. The setting of the sliding rod 202 can support the sliding seat 203 while limiting the moving trajectory of the sliding seat 203, thereby improving the stability of the sliding seat 203 during the movement.

When the connecting rod 706 moves, it can drive the moving block 704 fixedly connected at one end thereof to move. When the moving block 704 moves, it can slide on the outer surface of the limiting rod 703 and squeeze the spring 705 at the same time. The elastic force of the spring 705 continuously pushes the moving block 704, so that the moving block 704 cooperates with the connecting rod 706 to drive the auxiliary wheel 707 to push the transmission belt 603, thereby enabling the transmission belt 603 to always remain in a tensioned state.
