Description

Technical Field

[0001] This utility model belongs to the technical field of shot blasting machine devices, specifically relating to a shot conveying pipe opening adjustment mechanism. Background Technology

[0002] The shot blasting unit is the core component of a shot blasting machine. Its main function is to propel a medium (such as steel shot or silica sand) at high speed to impact the surface of the workpiece, thereby cleaning the workpiece surface. This machine is a high-performance continuous operation cleaning machine with continuous feeding. During the cleaning process, an electrically controlled variable frequency motor drives the roller conveyor to feed the workpiece into the blasting zone inside the cleaning chamber. The workpiece is subjected to impacts and friction from eight powerful and dense shot blasts from different coordinate directions, causing the oxide scale and dirt on the workpiece to quickly fall off, resulting in a smooth surface with a certain degree of roughness. The shot and rust dust falling onto the workpiece are conveyed to the shot circulation system via a recovery screw conveyor. During the cleaning process, the mixture of shot and dust that falls off is collected at the bottom of the elevator via the chamber funnel and longitudinal and transverse screw conveyors, and then lifted to the separator at the top of the machine. The separated, pure shot falls into the separator hopper for reuse in the shot blasting cycle. In this entire circulation system, there is a shot delivery pipe connected to the shot blaster. However, traditional shot delivery pipes do not have the ability to adjust the size of the opening and cannot cut off the shot from the separator, making it inconvenient to maintain the shot blaster. To address the above problems, a shot delivery pipe opening adjustment mechanism is proposed. Utility Model Content

The shot blasting machine body has a through hole, and a shot delivery pipe is connected to the shot blasting machine body through the through hole. An opening adjustment mechanism is provided between the shot blasting machine body and the shot delivery pipe. The opening adjustment mechanism includes a pipeline located between the shot blasting machine body and the shot delivery pipe. An opening is provided at the bottom of the pipeline. A ring gear is rotatably connected inside the pipeline. A gear rack is fixedly installed on the ring gear corresponding to the opening. Positioning rods are uniformly fixedly installed inside the pipeline. A non-circular opening and closing plate is rotatably connected to the positioning rod. A sector gear is fixedly installed on the non-circular opening and closing plate. The sector gear meshes with the ring gear. A gear is rotatably connected to the outside of the shot blasting machine body. The gear meshes with the gear rack. A bracket is fixedly installed on the outer side of the shot blasting machine body.

[0008] Furthermore, the irregularly shaped opening and closing plate is slidably connected to the inner wall of the pipeline.

[0009] The beneficial effects of this utility model are: This invention uses a motor to control the opening size of each irregularly shaped opening and closing plate, thereby adjusting the shot flow rate. The shot blasting production line consists of eight sets of cylinders, and the number of opening and closing gates can be arbitrarily combined according to the specifications of the workpiece to be cleaned, so as to save energy, reduce wear on the machine, and ensure that production needs are met; it can also realize the maintenance and upkeep of each shot blaster.

[0015] 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.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" 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 an indirect connection through an intermediate medium; 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.

[0017] Please refer to the accompanying diagrams in all instruction manuals: An opening adjustment mechanism for a shot delivery pipe includes a shot blasting machine body 1, a through hole 2 on the shot blasting machine body 1, a shot delivery pipe 3 connected to the shot blasting machine body 1 through the through hole 2, and an opening adjustment mechanism between the shot blasting machine body 1 and the shot delivery pipe 3. The opening adjustment mechanism includes a pipe 4 located between the shot blasting machine body 1 and the shot conveying pipe 3. An opening 5 is provided below the pipe 4. A ring gear 6 is rotatably connected inside the pipe 4. A toothed rack 7 is fixedly installed on the ring gear 6 corresponding to the opening 5. Positioning rods 8 are evenly fixedly installed inside the pipe 4. A special-shaped opening and closing plate 9 is rotatably connected to the positioning rod 8. A sector gear 10 is fixedly installed on the special-shaped opening and closing plate 9. The sector gear 10 meshes with the ring gear 6. A gear 11 is rotatably connected to the outside of the shot blasting machine body 1. The gear 11 meshes with the toothed rack 7. A bracket 12 is fixedly installed on the outer side of the shot blasting machine body 1. A motor 13 is fixedly installed on the bracket 12. The output end of the motor 13 is fixedly connected to the gear 11. As can be seen from the above description, the control motor 13 works, drives the gear 11 to rotate, causing the gear rack 7 to rotate, which in turn drives the ring gear 6 to rotate, causing the internal sector gears 10 to rotate around the positioning rod 8, which in turn drives the irregular opening and closing plate 9 to rotate. When it is necessary to reduce the area of ​​the through hole 2, the irregular opening and closing plates 9 are controlled to move closer to each other. When it is necessary to increase the area of ​​the through hole 2, the irregular opening and closing plates 9 are controlled to move further apart from each other.

[0018] As a technical optimization of this utility model, a collection groove 14 is provided on the bracket 12 corresponding to the opening 5; As can be seen from the above description, the collecting tank 14 can collect the debris at the opening 5, as well as the debris generated by mechanical friction between the gear 11 and the gear rack 7.

[0019] As a technical optimization of this utility model, the area of ​​the irregular opening and closing plate 9 is larger than the area of ​​the through hole 2; As can be seen from the above description, it is necessary to ensure that the irregularly shaped hinged plates 9 can completely cover the through hole 2 when they are closed.

[0020] As a technical optimization of this utility model, the shot blasting machine body 1 is composed of an impeller, blades, shot distribution wheel, directional sleeve, inlet pipe and drive motor, etc. As can be seen from the above description, the drive motor drives the impeller to rotate at high speed, usually reaching thousands of revolutions per minute or even higher, which sprays out small metal balls to clean the surface of the workpiece.

[0021] As a technical optimization of this utility model, the irregularly shaped opening and closing plate 9 is slidably connected to the inner wall of the pipeline 4; As can be seen from the above description, the sliding connection method creates a relatively sealed environment between the irregularly shaped opening and closing plate 9 and the pipeline 4, reducing the leakage of metal balls out of the pipeline 4 or the jamming of the irregularly shaped opening and closing plate 9.

[0022] The present invention and its embodiments have been described above. This description is not restrictive, and the specific embodiments shown are only one of the embodiments of the present invention. The actual structure is not limited to this.
