Description

Technical Field

[0001] The utility model relates to the technical field of sandblasting equipment, in particular to a cleaning device for a conveying component of a sandblasting machine. Background Art

[0002] The sandblasting machine uses compressed air as its power to form a high-speed jet beam to spray the material at high speed onto the surface of the workpiece to be processed, so that the appearance or shape of the outer surface of the workpiece changes. Due to the impact and cutting action of the abrasive on the workpiece surface, the surface of the workpiece acquires a certain degree of cleanliness and different degrees of roughness, and the mechanical properties of the workpiece surface are improved, thereby improving the fatigue resistance of the workpiece, increasing the adhesion between it and the coating, extending the durability of the coating, and also facilitating the leveling and decoration of the coating.

[0003] Existing conveyor-type sandblasting machines usually use conveyor mesh belts for loading and unloading. The sand and gravel sprayed by the sandblasting machine will fall from the mesh on the conveyor mesh belt for collection. However, after the sandblasting machine has been used for a period of time, some sand and waste will remain on the surface of the conveyor mesh belt, which will cause the mesh belt conveyor to be corroded and cause mechanical damage. At the same time, the sand and waste exist on the surface of the conveyor mesh belt for a long time, which will cause fatigue of the conveyor mesh belt and shorten its service life.

DETAILED DESCRIPTION

[0019] The following will be combined with the embodiments to clearly and completely describe the technical solution 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 of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-Figure 3 , the utility model provides a technical solution:

[0021] like Figure 1-Figure 3 As shown, a cleaning device for a conveying assembly of a sandblasting machine comprises a sandblasting box 1 and a conveyor mesh belt 2, a material receiving box 3 is provided below the conveyor mesh belt 2, a belt drive assembly 4, a roller brush 7 and a knocking assembly 6 are provided on the side of the material receiving box 3 close to the feeding end of the conveyor mesh belt 2, the roller brush 7 is located below the conveyor mesh belt 2, and the roller brush 7 is driven to rotate by the belt drive assembly 4; the knocking assembly 6 is located on the inner side of the material receiving box 3, a reducer 5 is provided between the knocking assembly 6 and the belt drive assembly 4, the knocking assembly 6 reciprocates in the vertical direction through the belt drive assembly 4 and the reducer 5, a rubber hammer 610 is provided in the knocking assembly 6, and the rubber hammer 610 is located below the conveyor mesh belt 2.

[0022] Through the above technical solution, the workpiece is placed on the feeding end of the conveyor mesh belt 2, and enters the sandblasting box 1 as the conveyor mesh belt 2 rotates. The workpiece is sandblasted by the sandblasting assembly in the sandblasting box 1. At this time, most of the sand and gravel will fall from the mesh of the conveyor mesh belt 2 into the receiving box 3 below, but some sand and gravel will still remain on the conveyor mesh belt 2. At this time, the workpiece that has been sandblasted is taken away through the discharging end of the conveyor mesh belt 2. The side of the conveyor mesh belt 2 that has been sandblasted faces downward as it rotates. At this time, part of the remaining sand and gravel will fall into the receiving box 3 under the action of gravity.

[0023] Then, as the conveyor mesh belt 2 continues to rotate, a section of the conveyor mesh belt 2 that has been sandblasted approaches the roller brush 7, and the roller brush 7 is driven to rotate by the belt transmission component 4, so that the mesh of the conveyor mesh belt 2 can be cleaned. At the same time, while the belt transmission component 4 rotates, the deceleration effect of the reducer 5 drives the knocking component 6 to move back and forth slowly, and the knocking component 6 knocks the conveyor mesh belt 2, thereby shaking off the gravel and waste remaining on the conveyor mesh belt 2, further improving the cleaning effect of the conveyor mesh belt 2.

[0024] The roller brush 7 and the knocking assembly 6 can play a dual cleaning role on the conveyor belt 2, and the synchronous operation is achieved through the rotation of the roller brush 7 and the knocking of the knocking assembly 6 through a power source of the belt transmission assembly 4.

[0025] The specific working principle is as follows: the belt drive assembly 4 is driven to rotate by the motor, thereby driving the roller brush 7 to rotate. When the motor drives the driving shaft 401 to rotate, since one end of the driving shaft 401 is connected to the reducer 5, the power of the driving shaft 401 is transmitted to the output shaft of the reducer 5 through the deceleration effect of the reducer 5. At this time, the output shaft speed of the reducer 5 is less than the speed of the driving shaft 401. The knocking frequency of the rubber hammer 610 can be conveniently adjusted through the reducer 5.

[0026] Furthermore, the lever 403 rotates with the rotation of the output shaft, and the lever 403 abuts against the protrusion 603 on the first wedge-shaped slider 602 during the rotation process, and then the lever 403 drives the first wedge-shaped slider 602 to overcome the elastic force of the first spring 605 and slide horizontally along the first slide groove 601. After the first wedge-shaped slider 602 slides horizontally, the first inclined surface 604 on the first wedge-shaped slider 602 and the second inclined surface 607 on the second wedge-shaped slider 606 form an inclined surface match, thereby realizing the second wedge-shaped slider 606 sliding in the vertical direction along the second slide groove 608, and then driving the rubber hammer 610 above the second wedge-shaped slider 606 to move toward the conveyor mesh belt 2. When the lever 403 drives the protrusion 603 to reach the farthest distance, the rubber hammer 610 abuts against the conveyor mesh belt 2 to complete the knocking.

[0027] When the lever 403 rotates and disengages from the bump 603, the first wedge-shaped slider 602 is reset under the elastic force of the first spring 605, and then the second wedge-shaped slider 606 is reset under the elastic force of the second spring 609, and the rubber hammer 610 moves away from the conveyor belt 2, and the knocking assembly 6 is reset. Then, as the lever 403 is again in contact with the bump 603, the rubber hammer 610 repeatedly knocks the conveyor belt 2.

[0028] Finally, the gravel and dust shaken off by the roller brush 7 and knocking are accumulated at the bottom through the funnel-shaped receiving box 3 to complete the recovery.

[0029] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be protected by the claims attached to the utility model.
