Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, specifically a through-type shot blasting machine with a protective structure. Background Technology

[0002] Through-type shot blasting machines are widely used in steel structures, shipbuilding, automobile manufacturing, machinery manufacturing and other fields to remove rust, descaling and increase surface roughness of workpieces. The working principle of through-type shot blasting machines is mainly based on the impact and friction of shot on the surface of the object being treated.

[0003] Referring to patent application CN218194608U, a rust removal structure for a through-feed shot blasting machine includes a rust removal box and a cleaning component. The cleaning component is fixedly connected to the lower part of the rust removal box. The cleaning component includes a collection hopper that works in conjunction with the rust removal box. A semi-circular arc plate is fixedly connected to the internal cavity of the cleaning box. A toggle plate is fitted onto the upper part of the semi-circular arc plate inside the cleaning box. The toggle plate is fixedly connected to the output shaft of a reduction motor via a rotating shaft. A flushing nozzle is fixedly connected to the side wall of the cleaning box. This utility model utilizes the cleaning component to collect the shot blasting and the removed rust impurities from the rust removal box into the internal cavity of the cleaning box. Combined with the flushing nozzle installed on the side wall of the cleaning box, the flushing nozzle sprays cleaning water that impacts the shot blasting, removing rust impurities from the shot blasting. This allows the shot blasting discharged from the box to be directly reused without the need for separate processing using other equipment. The structure is simple and the operation is convenient.

[0004] As shown in the prior art, the existing through-type shot blasting machine generates a large amount of rust dust during the shot blasting process inside the machine. The existing shot blasting machine will install curtains on both sides of the passage to prevent excessive dust from flying out of the shot blasting machine and polluting the working environment. However, even with only curtains to block dust, a lot of dust will still fly out due to gaps created by the curtains being lifted when the workpiece enters and exits the shot blasting machine.

[0005] Therefore, it is necessary to provide a through-type shot blasting machine with a protective structure to solve the above-mentioned technical problems. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides two technical solutions:

[0023] Figures 1 to 2 The first embodiment is shown: a through shot blasting machine with a protective structure, including a conveying device 2 for transporting workpieces, a protective cover 1 fixed in the middle of the conveying device 2, both sides of the protective cover being open and both being fixed with curtains 15, and a shot blasting assembly 3 for shot blasting workpieces passing through the protective cover 1 being installed on the top of the protective cover 1.

[0024] Dust-collecting components are installed on the top of the protective cover 1 corresponding to the two open sides. The dust-collecting components are used to absorb the rust dust that flies out of the curtain 15 when the curtain 15 is opened.

[0025] The dust collection assembly includes two dust collection hoods 4, which are respectively fixed to the top of the two open sides of the protective cover 1. The dust collection hoods 4 are open. A main pipe 5 is fixed to the side wall of the protective cover 1. The discharge ports of the two dust collection hoods 4 are respectively connected to the main pipe 5 through auxiliary pipes 7. An air pump 6 is fixed to the side wall of the protective cover 1. The main pipe 5 is connected to the inlet of the air pump 6, and a collection component for collecting dust is installed between the main pipe 5 and the air pump 6.

[0026] A protective cover 1 is fixed in the middle of the conveying device 2 of the shot blasting machine, and curtains 15 are set on both sides of the protective cover 1. So when the workpiece enters or exits the protective cover 1, although the curtains 15 will be lifted to create gaps, the patent has installed dust suction components on the top of the protective cover 1 corresponding to the two open sides. These components can absorb the rust dust that may be scattered outside the curtains 15 when they are opened, thus significantly enhancing the overall dustproof effect and protecting the working environment.

[0027] Figures 2 to 3 The second embodiment is shown. The main difference from the first embodiment is that the collection component includes a fixed shell 8 fixed to the side wall of the protective cover 1. The lower end of the fixed shell 8 is connected to the air pump 6, and the upper end of the fixed shell 8 is connected to the main pipe 5. A collection box 9 is slidably connected inside the fixed shell 8. The collection box 9 has an opening at the top and a filter screen 10 fixed at the bottom. A buckle assembly is installed on the fixed shell 8 to position the collection box 9 inside the fixed shell 8.

[0028] The buckle assembly includes an outer shell 11 fixed to the top of the fixed shell 8. The outer shell 11 is located on the side away from the open side of the fixed shell 8. A buckle 12 is slidably connected inside the outer shell 11. The lower end of the buckle 12 is trapezoidal and passes through the fixed shell 8. A pull block 13 is fixed through the outer shell 11 at the upper end of the buckle 12. A spring 14 is fixed inside the outer shell 11. The end of the spring 14 away from the pull block 13 is fixed to the buckle 12. The lower end of the buckle 12 is movably connected to the collection box 9.

[0029] The design of the collection components makes dust collection simple and easy. The collection box 9 and filter screen 10 are connected by a sliding connection, which can easily collect and filter dust. At the same time, the design of the snap-fit ​​components makes the disassembly and replacement of the collection box 9 simple and quick, which is conducive to the regular handling of dust and the cleaning and maintenance of the collection box 9.

[0030] Working principle:

[0031] Shot blasting component 3 is a through shot blasting machine, which is a mature existing technology and will not be described in detail here.

[0032] The workpiece to be processed enters the protective cover 1 through the conveying equipment 2, and the shot blasting assembly 3 performs shot blasting treatment on the workpiece entering the protective cover 1. Since the curtain 15 is lifted when the workpiece enters and exits the protective cover 1, and the shot blasting treatment will cause rust dust to fly out, the rust dust can easily fly out through the gap of the curtain 15. At this time, the dust is absorbed by the dust collection assembly.

[0033] When the air pump 6 is activated, the dust flying out of the door curtain 15 is sucked into the dust hood 4. The dust sucked into the dust hood 4 is transported to the main pipe 5 through the secondary pipe 7, and then enters the collection box 9 in the fixed shell 8 through the main pipe 5. The dust is collected on the filter screen 10 in the collection box 9. When it is necessary to empty the collection box 9, pull the pull block 13 upward to make the locking strip 12 enter the outer shell 11. At the same time, the spring 14 is compressed until the locking strip 12 is away from the collection box 9. At this time, the collection box 9 can be pulled out of the fixed shell 8 for cleaning. The empty collection box 9 is directly sent into the fixed shell 8. When one end of the collection box 9 presses against the inclined surface of the locking strip 12, the locking strip 12 is squeezed into the outer shell 11. The spring 14 is compressed until the collection box 9 is completely inside the fixed shell 8. Then the locking strip 12 springs back and locks the collection box 9 into the fixed shell 8.
