Description

Technical Field

[0001] The utility model relates to the technical field of shot blasting machines, in particular to a shot blasting machine with a cleaning component. Background Art

[0002] The shot blasting machine drives the projectile through an electric mechanical shot blasting wheel. Under the action of high-speed centrifugal force, the projectile forms a fan-shaped beam and is projected onto the surface of the metal workpiece. This process can peel off the oxide scale, rust, etc. on the surface of the workpiece, thereby achieving the effect of cleaning the workpiece.

[0003] When the above-mentioned shot blasting machine is used to grind the metal surface, a large number of high-speed steel shots will knock the oxides on the metal surface into powder. The fine oxide impurities will diffuse and adhere to the inner wall of the shot blasting machine, thereby forming excess impurities inside the shot blasting machine. The excess impurities will accumulate more and more and are easily vibrated and fall off in large quantities on the surface of the metal workpiece during the subsequent metal grinding process, thereby reducing the effect of the shot blasting machine in grinding the metal.

DETAILED DESCRIPTION

[0023] 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.

[0024] When the shot blasting machine is working, the high-speed rotating impeller will drive the steel shot to quickly impact the surface of the metal workpiece, causing the oxide on the metal surface to become impurity particles and separate from the surface of the metal workpiece. A large number of metal impurity particles will adhere to the surface of the processing chamber due to diffusion movement, causing the impurities on the surface of the processing chamber to accumulate more and more. When accumulated to a certain extent, they are easy to fall off, affecting the effect of the shot blasting machine on grinding metal. Based on this, the following solution is provided to solve the above problems.

[0025] Example 1

[0026] When the existing shot blasting machine grinds metal workpieces, a large amount of diffused oxide particle impurities adhere to the surface of the processing chamber, thereby reducing the grinding effect of the metal workpiece. This embodiment provides a shot blasting machine with a cleaning component, such as Figure 1-Figure 3 As shown, it involves a shot blasting machine body 1, which drives the impeller to rotate at high speed after being powered on, so that the projectiles have high-speed centrifugal force and hit the surface of the metal workpiece placed in the processing chamber 2, so as to achieve the purpose of removing impurities such as oxides on the metal surface. The processing chamber 2 is arranged inside the shot blasting machine body 1, and a cleaning mechanism 3 for cleaning the processing chamber 2 is arranged inside the shot blasting machine body 1, which can circulate and clean the inner wall of the processing chamber 2, so that fine impurity particles will not be deposited and attached to the inner wall of the processing chamber 2, thereby not affecting the normal grinding of the metal workpiece in the processing chamber 2;

[0027] The cleaning mechanism 3 includes a motor 31 installed in the processing chamber 2 and a concave frame 32 slidably installed in the processing chamber 2. A first sprocket 33 is provided at one end of the output shaft of the motor 31. A second sprocket 34 is rotatably connected in the shot blasting machine body 1. A chain 35 is provided between the first sprocket 33 and the second sprocket 34. A conversion member 36 for cooperating with the chain 35 to drive the concave frame 32 is provided between the chain 35 and the concave frame 32. A brush 37 is provided on the side of the concave frame 32 close to the processing chamber 2. The brush 37 is in contact with the processing chamber 2. When this embodiment is implemented, the shot blasting machine body 1 operates normally, metal grinding is performed inside the processing chamber 2, and the motor 31 operates normally at the same time. When impurities such as oxides on the surface of the metal workpiece are impacted into powder by high-speed projectiles and attached to the surface of the processing chamber 2 with diffusion movement, the motor 31 drives the first sprocket 33 and the chain 35 to rotate. When the second sprocket 34 rotates, the chain 35 continues to move in the shot blasting machine body 1. At this time, the conversion piece 36 at the lower end of the chain 35 will pull the rectangular frame to reciprocate in the processing chamber 2, and at the same time make the brush 37 on the surface of the rectangular frame slide on the surface of the processing chamber 2, thereby removing the foreign particles attached to the surface of the processing chamber 2, reducing the occurrence of a large number of foreign particles attached to the inner surface of the processing chamber 2, which is beneficial to improving the grinding efficiency of the metal workpiece in the shot blasting machine body 1, wherein the first sprocket 33 and the second sprocket 34 have the same inner diameter size. Since the first sprocket 33 and the second sprocket 34 are driven by the chain 35, the linear speed of the first sprocket 33 and the second sprocket 34 are always the same. When the inner diameter size of the first chain 35 and the second chain 35 is the same, the angular velocity of the two is the same, thereby keeping the guide rod 361 moving at the lower end of the chain 35 basically in a uniform speed state.

[0028] The conversion member 36 includes a guide rod 361 rotatably connected to the chain 35, and a rectangular plate 362 is provided on the side of the concave frame 32 close to the guide rod 361. A rectangular groove 363 is provided in the rectangular plate 362 for use with the guide rod 361. Since the guide rod 361 rotates at the lower end of the chain 35, and the guide rod 361 follows the movement of the chain 35, and the guide rod 361 moves in the rectangular groove 363, the guide rod 361 drives the rectangular plate 362 to move during the movement, so that the rectangular plate 362 follows the guide rod 361 to reciprocate in the processing chamber 2, which is beneficial for the rectangular plate 362 to continuously drive the brush 37 to perform cleaning work.

[0029] Limit blocks 38 are provided on both sides of the rectangular plate 362, and a limit groove 39 for slidingly installing the limit block 38 is provided in the processing chamber 2. Since the rectangular plate 362 reciprocates in the processing chamber 2, and the rectangular plate 362 moves in the processing chamber 2 through the pulling of the guide rod 361, when the limit block 38 slides in the limit groove 39, it can prevent the rectangular plate 362 from tilting in the processing chamber 2 due to uneven force on the rectangular plate 362, which is beneficial to maintaining the state of the brush 37 during normal operation.

[0030] Example 2

[0031] Since the brush 37 will contain a certain amount of impurity particles when cleaning the oxide impurity particles attached to the processing chamber 2, which will affect the effect of the brush 37 in cleaning the oxide impurities, based on Example 1, Figure 4 As shown, two groups of bumps 4 are symmetrically arranged in the processing chamber 2, which make the brush 37 shake when it comes into contact with it. Since the brush 37 reciprocates in the processing chamber 2 and removes the oxide impurity particles on the surface of the processing chamber 2, and during use, the granular impurities contained in the brush 37 will accumulate more and more. When the brush 37 moves to both sides of the processing chamber 2 respectively, it will come into contact with the bump 4 on one side and slide on the surface of the bump 4, causing the brush 37 to shake and remove the impurity particles contained therein.

[0032] The bumps 4 are arranged axially in a continuous and irregular manner in the processing chamber 2. Since foreign particles are mixed in the brush 37, when the brush 37 moves on the surface of the irregularly continuously arranged bumps 4, the brush 37 will vibrate to a certain extent, causing the foreign particles in the brush 37 to fall off.

[0033] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
