Abstract
Description
Technical Field
[0001] This utility model relates to the field of shot blasting machine technology, and in particular to a shot circulation device for shot blasting machines. Background Technology
[0002] Shot blasting machine is a casting equipment that uses high-speed shot to clean or strengthen the surface of castings. Shot blasting machine can simultaneously remove sand, core and clean castings. It is a processing technology that uses shot blasting machine to throw steel shot at high speed to impact the surface of material objects.
[0003] When using a shot blasting machine to polish workpieces, waste chips, dust and other impurities easily adhere to the shot. If these impurities are not cleaned, they will cause pits on the workpiece surface after contact with the workpiece, affecting the polishing effect.
[0004] Existing shot blasting machines typically use a fan to clean surface impurities during shot recycling. However, due to shot accumulation, the cleaning effect is poor. Therefore, a shot recycling device for shot blasting machines is proposed. Utility Model Content
[0005] The main purpose of this utility model is to provide a shot circulation device for shot blasting machines, which distributes the collected shot evenly in the hopper through shot blasting rollers and treats the dust with a fan, which can effectively solve the problems in the background art.
[0006] To achieve the above objectives, this utility model provides a shot circulation device for a shot blasting machine, including a lifting box, a shot blasting roller, and a blower;
[0007] The lifting box has a discharge port on one side, and a roller and a conveyor belt are provided inside the lifting box. A first motor is connected to one side of the roller, and hoppers are arrayed on the conveyor belt. The trough of the hopper is provided with a leakage hole.
[0008] One side of the shot blasting roller is connected to the side of the lifting box away from the discharge port. A feed hopper is connected to the shot blasting roller. A second motor is connected to one side of the shot blasting roller. Multiple shot grooves are arranged in a circular array on the shot blasting roller.
[0009] The blower is installed on the side of the lifting box away from the discharge port. The lifting box has an air inlet, and the blower blows air towards the hopper through the air inlet.
[0010] Based on the above technical solution, the present invention can be further improved as follows.
[0011] Furthermore, a cleaning window is provided on one side of the lifting box, and a dust collection box is detachably installed inside the cleaning window.
[0012] Furthermore, both the drain hole and the air inlet are inclined, so that when the hopper rotates to one side of the air inlet, the drain hole and the air inlet are on the same straight line.
[0013] Furthermore, the shot blasting roller rotates intermittently under the drive of a second motor.
[0014] Furthermore, the diameter of the projectile groove is larger than the diameter of the projectile, and the diameter of the leakage hole is smaller than the diameter of the projectile.
[0015] The beneficial effects of this utility model are as follows: This utility model provides a shot circulation device for a shot blasting machine, which has the following advantages:
[0016] 1. This utility model, by setting up a shot blasting roller, collects used shot into the feed hopper. The second motor drives the shot blasting roller to rotate intermittently. During the rotation of the shot blasting roller, a certain amount of shot falls into the shot groove of the shot blasting roller and rotates together with the shot blasting roller. Under the action of centrifugal force, it is thrown into the corresponding hopper. Through the cooperation of multiple hoppers and the intermittently rotating shot blasting roller, the shot can be thrown into the hopper when it falls, and the number of shot in each hopper is approximately the same, avoiding the problem of shot accumulation in the hopper, which would affect the low shot blasting rate.
[0017] 2. This utility model, by setting an inclined vent and air inlet, allows the shot to be lifted from the bottom of the lifting box to the top discharge port along with the hopper. During the lifting process, the blower blows air out of the shot in the hopper. Under the action of the wind, waste, dust and other impurities on the shot leave the hopper through the vent, thereby cleaning the shot in the hopper and enabling the shot to meet the standard of recycling.

[0028] like Figure 1-4 As shown, this utility model provides a shot circulation device for a shot blasting machine, including a lifting box 1, a shot blasting roller 6 and a blower 11;
[0029] The lifting box 1 has a discharge port 10 on one side. The lifting box 1 is equipped with a roller 2 and a conveyor belt 3. A first motor 4 is connected to one side of the roller 2. A hopper 5 is arranged on the conveyor belt 3. The groove of the hopper 5 is provided with a leakage hole 12. The diameter of the leakage hole 12 is smaller than the diameter of the bullet.
[0030] A cleaning window 15 is also provided on one side of the bottom of the lifting box 1, and a dust collection box 14 is detachably installed inside the cleaning window 15;
[0031] One side of the shot blasting roller 6 is connected to the side of the lifting box 1 away from the discharge port 10. The shot blasting roller 6 is connected to the feed hopper 7. One side of the shot blasting roller 6 is connected to the second motor 8. The shot blasting roller 6 rotates intermittently under the drive of the second motor 8. The shot blasting roller 6 has a plurality of shot grooves 9 arranged in a circular array. The diameter of the shot grooves 9 is larger than the diameter of the shot.
[0032] The blower 11 is installed on the side of the lifting box 1 away from the discharge port 10. The lifting box 1 is provided with an air inlet 13. The drain hole 12 and the air inlet 13 are both inclined. When the hopper 5 rotates to the side of the air inlet 13, the drain hole 12 and the air inlet 13 are on the same straight line.
[0033] In this embodiment, the used shot is collected into the feed hopper 7. The second motor 8 drives the shot blasting roller 6 to rotate intermittently. During the rotation of the shot blasting roller 6, a certain amount of shot falls into the shot groove 9 of the shot blasting roller 6. As the shot blasting roller 6 rotates together, it is thrown into the corresponding hopper 5 under the action of centrifugal force, thereby achieving the purpose of controlling the number of shot in each hopper 5 and avoiding the problem of shot accumulation in the hopper 5, resulting in a low shot blasting rate.
[0034] In this embodiment, the shot is lifted from the bottom of the lifting box 1 to the top discharge port 10 along with the hopper 5. During the lifting process, the blower 11 blows air out of the shot in the hopper 5 to blow off the waste, dust and other impurities on the shot, thereby cleaning the shot and realizing the recycling of the shot.
[0035] Preferably, the cleaning window 15 is connected to an external vacuuming device. The debris, dust and other impurities blown off the projectile leave the lifting box 1 through the cleaning window 15 under the action of wind, avoiding the trouble of frequent replacement of the dust collection box 14 when it is full, and better collecting the blown-off impurities to avoid secondary pollution.
[0036] The working principle is as follows:
[0037] Used shot is collected in the feed hopper 7. The second motor 8 drives the shot blasting roller 6 to rotate intermittently. During the rotation of the shot blasting roller 6, a certain amount of shot falls into the shot groove 9 of the shot blasting roller 6. As the shot blasting roller 6 rotates together, it is thrown into the corresponding hopper 5 under the action of centrifugal force. Through the cooperation of multiple hoppers 5 and the intermittently rotating shot blasting roller 6, the shot is thrown into the hopper 5 during blasting, and the number of shot in each hopper 5 is approximately the same, thereby avoiding the accumulation of shot in the hopper 5. The phenomenon of shot accumulation occurs when the shot is lifted from the bottom of the lifting box 1 to the top discharge port 10 along with the hopper 5. During the lifting process, the blower 11 blows air out of the shot in the hopper 5. Under the action of the air, waste, dust and other impurities on the shot leave the hopper 5 through the leakage hole 12, thereby cleaning the shot in the hopper 5 and making the shot meet the standard for recycling. Similarly, under the action of centrifugal force, the clean shot is thrown to the discharge port 10 and transported from the discharge port 10 to the shot blasting machine for recycling.
[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
