[0003] Based on what is stated in the above documents: In the current refined wire production process, the role of the through-type sandblasting machine is vital. It effectively cleans impurities and irregularities on the surface of the wire by spraying sand particles at high speed, providing a solid foundation for subsequent processing. However, this link also faces a series of technical challenges, especially when dealing with high-speed flying sand particles. These high-speed moving sand particles have extremely high speed and sharp characteristics, which cause serious wear on the traditional rolling guide wheel. The guide wheel is a key component for wire transmission, and its stability and durability are crucial to the smooth progress of the sandblasting process. However, under the continuous impact of high-speed sand particles, the guide wheel is difficult to maintain stable operation for a long time, which not only affects the stability of the wire during the sandblasting process, but also directly leads to a decline in the quality of the wire. For this reason, the utility model provides a through-type wire sandblasting machine. Utility Model Content

[0025] A through-type wire sandblasting machine includes a workbench 1, a sandblasting box 2 is fixedly connected to the top of the workbench 1, a cleaning mechanism 3 is provided inside the sandblasting box 2, and positioning mechanisms 4 are provided on both sides of the sandblasting box 2. The positioning mechanism 4 includes:

[0026] The positioning assembly 41 includes a rotating ring 411 rotatably mounted on one side of the sandblasting box 2. A rotating rod 412 is rotatably connected to the interior of the rotating ring 411. One end of the rotating rod 412 causes a positioning block 413 to slide through the transmission assembly 5. A positioning ball 414 is installed inside the positioning block 413.

[0027] The driving assembly 42 is arranged at the bottom of the workbench 1 .

[0028] Slots for the wire to pass through are provided on both sides of the sandblasting box 2. The positioning ball 414 is rolled inside the positioning block 413. When the wire is clamped and positioned, it will roll with the movement of the wire, without affecting the normal transportation of the wire. The wire is driven by an external motor to rotate the winding roller, and the winding roller drives the wire to be transported.

[0029] In this embodiment, the transmission assembly 5 includes a transmission block 51 installed on one side of the sandblasting box 2, and a transmission plate 52 is slidably connected inside the transmission block 51. One end of the transmission plate 52 is fixedly connected to one side of the positioning block 413, and one side of the transmission plate 52 is rotatably connected to one end of the rotating rod 412.

[0030] The transmission block 51 is used to slide and limit the transmission plate 52 .

[0031] In this embodiment, the driving assembly 42 includes a driving cylinder 421 installed at the bottom of the workbench 1. The top of the driving cylinder 421 is slidably connected to a piston rod 422, and the top end of the piston rod 422 is fixedly connected to the other end of the transmission plate 52.

[0032] The driving cylinder 421 is connected to an external air source through an air pipe, and the piston rod 422 slides inside the workbench 1 .

[0033] The through-type wire sandblasting machine starts the driving cylinder 421 to drive the piston rod 422 and the transmission plate 52 below to slide upward synchronously. The transmission plate 52 below slides inside the transmission block 51. The sliding of the transmission plate 52 drives the positioning block 413 and the positioning ball 414 to slide synchronously. The sliding of the transmission plate 52 causes one end of the rotating rod 412 to rotate on one side of the transmission plate 52, and the other end of the rotating rod 412 rotates inside the rotating ring 411, thereby causing the rotating ring 411 to rotate. The rotation of the rotating ring 411 causes the other two groups of rotating rods 412 to rotate synchronously, so that The three groups of transmission plates 52, positioning blocks 413 and positioning balls 414 are synchronously slid toward the center, and the wire is clamped and positioned by the positioning balls 414. The positioning mechanism 4 is provided, and the three groups of positioning blocks 413 and positioning balls 414 are driven by the driving cylinder 421 to slide synchronously. The three groups of positioning balls 414 can clamp and position wires of different sizes, so that the wire passing through the sandblasting box 2 remains in a straight state, avoiding bending or looseness, and keeping the wire stable during the transportation process, thereby improving the subsequent cleaning quality.

[0034] Example 2

[0035] The main differences from Example 1 are:

[0037] A slot is defined at the bottom of the supporting plate 31 , and the size of the slot is consistent with that of the connecting block 33 .

[0038] In this embodiment, a control motor 6 is installed on the top of the sandblasting box 2. One end of the output shaft of the control motor 6 is fixedly connected to a control gear 7 through a coupling. The surface of the control gear 7 is meshed with the surface of the rotating gear 37.

[0039] The control motor 6 is a three-phase asynchronous motor and is connected to an external circuit through wires.

[0040] In this embodiment, symmetrical support rods 8 are installed on the inner wall of the sandblasting box 2 , and multiple groups of sandblasting guns 9 are installed on the surface of the support rods 8 .

[0041] One side of the sandblasting gun 9 is communicated with an external sand material barrel through a connecting pipe.

The rotation of the control gear 7 drives the rotating gear 37, the cleaning circular plate 35 and the cleaning brush 36 to rotate synchronously. The cleaning circular plate 35 rotates inside the fixed ring 34, and the impurities remaining on the surface of the wire are cleaned by the cleaning brush 36. By providing a cleaning mechanism 3, the cleaning brush 36 is used to clean the surface of the wire after sandblasting under the drive of the control motor 6 to avoid impurities remaining on the surface of the wire.

[0043] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0044] During operation, first pass the wire through the notches on both sides of the sandblasting box 2, and start the driving cylinder 421 to drive the piston rod 422 and the transmission plate 52 below to slide upward synchronously, and the transmission plate 52 below slides inside the transmission block 51. The sliding of the transmission plate 52 drives the positioning block 413 and the positioning ball 414 to slide synchronously. The sliding of the transmission plate 52 causes one end of the rotating rod 412 to rotate on one side of the transmission plate 52, and the other end of the rotating rod 412 rotates inside the rotating ring 411, thereby causing the rotating ring 411 to rotate. The rotation of the rotating ring 411 causes the other two groups of rotating rods 412 to rotate synchronously, so that the three groups of transmission plates 52, positioning blocks 413 and the rotating ring 411 rotate synchronously. The rod slides toward the center synchronously with the positioning ball 414, and the wire is clamped and positioned by the positioning ball 414. The positioning components 41 set on both sides of the sandblasting box 2 keep the wire passing through the inside of the sandblasting box 2 in a straight state to avoid bending or loosening. Subsequently, sand particles are sprayed out by multiple groups of sandblasting guns 9 to remove dirt, oxide layer and other undesirable attachments on the surface of the wire. Finally, the control motor 6 is started to drive the control gear 7 to rotate. The rotation of the control gear 7 drives the rotating gear 37, the cleaning circular plate 35 and the cleaning brush 36 to rotate synchronously. The cleaning circular plate 35 rotates inside the fixed ring 34, and the impurities remaining on the surface of the wire are cleaned by the cleaning brush 36.
