Description

Technical Field

[0001] The utility model relates to the field of shot blasting machines, in particular to a closed structure of a shot blasting chamber of a shot blasting machine. Background Art

[0002] In an existing through-type shot blasting machine, a rubber strip with a width of about 150MM is installed at the entrance of the shot blasting chamber. The function of the rubber strip is to facilitate the passage of the workpiece and to restore the original shape after the workpiece passes through, thus playing a sealing role. The Chinese utility model patent with application number 202022139965.2 discloses a sealed door curtain for a shot blasting machine. When the shot blasting machine processes the material, the staff can put down the curtain plate to achieve the sealing of the shot blasting machine, thereby reducing the amount of steel shots splashing out. At the same time, when the material is cleaned, the staff can raise the curtain plate to a suitable height. At the same time, the first rubber strip and the second rubber strip will not affect the output of the material.

[0003] The above-mentioned sealing door curtain can play a sealing role on both sides of the rubber strip. However, defects were found during use: in the case of long-term operation, the rubber strip is easily squeezed to one side by the workpiece, and the rubber strips are misaligned and overlapped, resulting in openings between the rubber strips, which in turn causes the internal projectiles and dust to overflow. And when the curtain plate is lowered in the case of misaligned and overlapping rubber strips, the curtain plate may be stuck or the rubber strip may be damaged. That is, after the workpiece passes through the rubber strip, the rubber strip cannot be combed to assist in its reset, and the rubber strip cannot be assisted in fixing on one side. Summary of the invention

[0025] 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. Example 1

[0026] like Figures 1 to 5 As shown, a closed structure of a shot blasting chamber of a shot blasting machine includes a rubber strip 11 arranged at the inlet of the shot blasting chamber 1, and vertical first magnetic strips 111 are fixedly provided at the left and right center positions of the outer side of the rubber strip 11, and a combing fixing structure cooperating with the rubber strip 11 is fixedly provided on the shot blasting chamber 1 outside the rubber strip 11, and the combing fixing structure includes an outer horizontal second magnetic strip 2 that attracts and cooperates with the first magnetic strip 111, and the outer side surface of the second magnetic strip 2 is fixed to the bottom of the inner side surface of a slide plate 3 that moves up and down, and the top of the slide plate 3 is fixed to the bottom surface of a cross bar 31, and the left and right ends of the cross bar 31 are respectively connected to a driving mechanism 4 that moves up and down.

[0027] The driving mechanism 4 includes a screw sleeve 41 with upper and lower openings fixed to both ends of the cross bar 31, the screw sleeve 41 is sleeved on a vertical screw 42, the bottom of the screw 42 is connected to a motor reducer 43, the motor reducer 43 is respectively fixedly connected to the outer side surface of the bottom of the shot blasting chamber 1, and the top surface of the screw 42 is rotatably embedded in a limit block 44 (square, with a blind hole embedded in the bottom, and a bearing that matches the top of the screw 42 is fixed in the blind hole), and the limit block 44 is fixed to the outer side surface of the top of the shot blasting chamber 1.

[0028] The second magnetic strip 2 passes through all the rubber strips 11 from left to right.
