Description

Technical Field

[0001] This utility model relates to the field of dust removal technology for shot blasting machines, and in particular to a rust and dust blowing device for shot blasting machines. Background Technology

[0002] The working principle of a shot blasting machine is to use high-speed shot projectiles thrown by a shot blaster to clean or strengthen the surface of a workpiece. Therefore, it inevitably generates a large amount of dust. Currently, most shot blasting machines have dust removal functions, usually by installing dust removal fans at the top or side of the shot blasting chamber to absorb the dust generated during the process. However, even with dust removal fans, it cannot be guaranteed that all dust will be absorbed. Some dust will fall onto the workpiece surface due to its weight, and some will adhere to the workpiece surface due to electrostatic attraction.

[0003] After shot blasting, the workpieces need to undergo additional dust removal. Usually, after the workers take the workpieces out of the shot blasting chamber, they use the air chamber to blow away the dust on the surface of the workpieces. However, this method is entirely manual and inefficient. In addition, it lacks dust prevention measures, and the dust blown out often gets everywhere, polluting the workshop environment. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model discloses a rust and dust blowing device for a shot blasting machine, including a support frame, a blow pipe, a linear module, and a rotary cylinder. The support frame is arranged horizontally in the shot blasting chamber of the shot blasting machine. The support frame includes a horizontal section and inclined sections symmetrically arranged on both sides of the horizontal section. The blow pipe is bent along the support frame and has multiple blow holes spaced apart on the side facing away from the support frame. The linear module is arranged longitudinally on the outer wall of both sides of the shot blasting chamber. The two ends of the support frame are connected to the linear modules on both sides through the rotary cylinder.

[0005] Furthermore, the sidewall of the shot blasting chamber is provided with a through groove along the longitudinal direction on both sides of the linear module, and the slider of the linear module is connected to the rotary cylinder through the through groove via connecting blocks.

[0006] Furthermore, accordion-style protective covers are provided on both the upper and lower sides of the connecting block within the through groove.

[0007] Furthermore, the rotating disk at the top of the rotating cylinder is fixedly connected to the end of the support frame via a connecting bracket.

[0008] Furthermore, a spiral telescopic air pipe is provided on the outer side of the top of the shot blasting chamber. One end of the spiral telescopic air pipe is connected to the blow pipe, and the other end is connected to an external air source.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] This invention uses a linear module to move the support frame up and down inside the shot blasting chamber to adjust the position of the blowpipe. A rotary cylinder drives the blowpipe to swing back and forth, causing it to blow dust around the workpiece. Part of the dust blown down falls into the dust removal chamber at the bottom of the shot blasting machine, while the other part is sucked away by the dust removal fan. The workpiece no longer needs manual dust removal, which shortens the overall shot blasting time and improves production efficiency. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0020] In the description of the embodiments, unless otherwise expressly specified and limited, the terms "set," "connect," etc., should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or a connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] like Figure 1 As shown, the rust and dust blowing device of the shot blasting machine in this embodiment includes a support frame 1, a blow pipe 2, a linear module 3, and a rotary cylinder 4. The support frame 1 is arranged horizontally in the shot blasting chamber 5 of the shot blasting machine. The support frame 1 includes a horizontal section and inclined sections symmetrically arranged on both sides of the horizontal section. The blow pipe 2 is bent along the support frame 1 and has multiple blow holes 21 spaced apart on the side facing away from the support frame 1. The linear module 3 is arranged longitudinally on the outer wall of both sides of the shot blasting chamber 5. The two ends of the support frame 1 are connected to the linear modules 3 on both sides through the rotary cylinder 4.

[0022] A spiral telescopic air pipe 6 is provided on the outer side of the top of the shot blasting chamber 5. One end of the spiral telescopic air pipe 6 is connected to the blow pipe 2, and the other end is connected to an external air source. The spiral telescopic air pipe 6 extends into the interior from the opening at the top of the shot blasting chamber 5. When the support frame 1 moves inside the shot blasting chamber 5, the spiral telescopic air pipe 6 can extend and retract accordingly. The external air source can be generated by the factory's own air compressor.

[0023] like Figure 2-3 As shown, the sidewalls of the shot blasting chamber 5 are provided with longitudinal through slots 51 on both sides of the linear module 3. The slider 31 of the linear module 3 is connected to the rotary cylinder 4 through the through slots 51 via connecting blocks 32. The rotating disk 41 at the top of the rotary cylinder 4 is fixedly connected to the end of the support frame 1 via a connecting bracket 42. The rotary cylinder 4 can be a rotary cylinder that can rotate within the range of 0-180°.

[0024] The upper and lower sides of the connecting block 32 are provided with bellows protective covers 52 in the through groove 51. The bellows protective covers 52 can be made of materials such as PVC, three-proof cloth, and nylon cloth. They are flexible, high temperature resistant, wear resistant, and have a long service life, which can effectively prevent dust from overflowing from the shot blasting chamber 5.

[0025] In the initial state, the support frame 1 and the blow pipe 2 are both located inside the shot blasting chamber 5 and above it, close to the rear side wall of the shot blasting chamber 5, so as to avoid the shot blasting path of the shot blaster.

[0026] like Figure 4As shown, after shot blasting is completed, the linear module 3 drives the support frame 1 and the blowpipe 2 to move downwards and closer to the workpiece surface. At the same time, the rotary cylinder 4 drives the support frame 1 and the blowpipe 2 to rotate 0-180°, so that the blowpipe 2 moves back and forth around the front and back sides, left and right sides and top of the workpiece to blow dust off the workpiece surface. Some of the heavier dust blown down falls into the dust removal chamber 7 at the bottom of the shot blasting chamber 5, while the lighter dust is sucked away by the dust removal fan 8. The blowing force of the blowpipe 2 can be controlled by adjusting the working pressure of the air compressor.

[0027] Workpieces treated in the above manner no longer require manual dust removal (or only simple dust removal is needed), which shortens the overall shot blasting time, reduces the workload of workers, and thus improves production efficiency.

[0028] It should be noted that the above embodiments only show the method of using the rust dust blowing device in conjunction with the rotary table shot blasting machine; similarly, the rust dust blowing device can also be used in conjunction with commonly used crawler shot blasting machines, roller conveyor shot blasting machines and some hanging shot blasting machines on the market.

[0029] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope claimed by this utility model.
