[0002] Silicon wafers are important raw materials for the photovoltaic and semiconductor industries. During the processing of silicon wafers, they need to be cut. At this time, a multi-wire cutting machine is needed. Its principle is to use the high-speed movement of the steel wire to drive the cutting blade at its outer end to rub against the outer end of the raw material. The friction produces an incision and finally completes the cutting.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4, a wire cutting machine wire drum, including a baffle 1 and a barrel 2, a central axis 3 is fixedly arranged at the center position of the right side of the baffle 1, a positioning column 4 is fixedly arranged on the right side of the baffle 1, and the positioning column 4 is located on one side of the central axis 3, a through hole is arranged on the central axis 3, two groups of limit blocks 6 are slidably arranged in the through hole, a gear 7 is rotatably arranged at the center position of the side wall of the through hole, racks 8 are fixedly arranged on the opposite sides of the limit blocks 6 on both sides, the racks 8 on both sides are distributed up and down, and the racks 8 are meshed with the gear 7, a mounting hole and a positioning hole are arranged on the barrel 2, an annular groove is arranged on the inner wall of the mounting hole, the central axis 3 extends into the mounting hole, the positioning column 4 extends into the positioning hole, the limit block 6 is adapted to the annular groove, and an operating wheel 5 is rotatably arranged on the right side of the central axis 3, and the operating wheel 5 is connected with the gear 7.

[0023] By rotating the operating wheel 5, the gear 7 drives the rack 8 to move, and further the limit block 6 can be driven to move in the through hole. When the limit block 6 extends out of the through hole and enters the annular groove in the mounting hole of the cylinder 2, the cylinder 2 can be fixed. When the cylinder 2 is worn and needs to be replaced, the operating wheel 5 is rotated to drive the limit block 6 to enter the through hole. At this time, the annular groove of the cylinder 2 loses its limit, so that the cylinder 2 can be separated from the baffle 1. When the baffle 1 is rotating, the centrifugal force causes the limit blocks 6 on both sides to always be located in the annular groove. Therefore, the cylinder 2 will not be separated from the baffle 1 when the structure is in use. The structure has the characteristics of easy replacement of the cylinder 2 and better practicality.

[0024] The above structure requires the cylinder 2 to have good stability when in use. In order to meet the above requirement, the positioning posts 4 and the positioning holes are provided with two groups of symmetrical distribution.

[0025] The operating wheel 5 needs to be prevented from slipping when in use. In order to meet the above requirement, the operating wheel 5 is provided with anti-slip grooves.

[0027] The above structure requires the limit block 6 to move with good stability when in use. In order to meet the above requirement, a slider 9 is fixedly provided on the inner wall of the through hole, and a guide hole is provided on the limit block 6. The slider 9 is slidably connected to the guide hole.

[0028] In this embodiment, the limit block 6 and the rack 8 are an integrated structure.
