Description

Technical Field

[0001] The utility model relates to the technical field of shot blasting machines, in particular to a feeding mechanism of a shot blasting machine and a sealing chamber thereof. Background Art

[0002] A shot blasting machine is a mechanical device that uses high-speed projectiles to clean or enhance the surface of a workpiece. It can simultaneously shake out sand, decore, and clean castings. It can also be used for surface treatment of forgings, aluminum-magnesium alloy parts, sheet metal weldments, and other components. Casting production lines require continuous product output, and the accompanying shot blasting machine must also meet the requirements for continuous cleaning of castings. Under these circumstances, the shot blasting machine cannot operate in a fully enclosed environment. Gaps inevitably exist at the connection between the vibrating conveyor and the shot blasting chamber, allowing steel shot to rebound through these gaps. The shot blasting machine's feed chamber is used to collect the randomly rebounding steel shot after blasting, ensuring that the steel shot does not rebound outside the shot blasting machine. These shot are also collected for subsequent recycling.

[0003] Currently, most shot containment devices, both domestically and internationally, utilize a built-in rubber curtain, installed above the connection between the vibrating conveyor and the shot blasting chamber. This built-in rubber curtain generally has a simple structure and blocks a single direction. However, due to the large number of rebounding steel shots, their substantial kinetic energy, and their random orientation, there is a high probability that the shots will bounce out of a single gap. Long-term operation of the shot blasting machine results in a decrease in the amount of recovered steel shots and an increase in shot consumption. Furthermore, the rebounded steel shots are scattered all over the floor, increasing the cleaning and collection effort. More seriously, the rebounded steel shots pose a risk of injury. Utility Model Content

[0004] In view of the above problems, the purpose of the present invention is to provide a shot blasting machine feeding mechanism and a sealing chamber thereof which can effectively buffer shot materials and prevent them from leaking.

[0005] In order to solve the above technical problems, the technical solution adopted by the present utility model is as follows: a shot blasting machine feeding sealing chamber, comprising an energy absorption chamber and a roller connecting chamber, a lower chute chamber is provided at the lower part of the roller connecting chamber, a first maze structure is provided at the side where the roller connecting chamber is connected to the roller, the first maze structure is an annular baffle arranged on the inside of the roller connecting chamber, a second maze body is provided on the outside of the lower chute chamber, and the second maze body is a baffle arranged at the groove of the lower chute chamber.

[0006] In the above technical solution, a detection mechanism is provided at the feed port on one side of the roller connecting chamber. The detection mechanism includes a detection frame, a rigid plate and a beam switch. The detection frame is installed on the energy absorption chamber, the rigid plate is hinged on the detection frame, and the beam switch is arranged on both sides of the rigid plate.

[0007] In the above technical solution, the baffles of the first labyrinth structure and the second labyrinth body are both rubber baffles, and their shapes are rectangular or crescent.

[0008] In the above technical solution, the energy absorbing chamber and the roller connecting chamber are both provided with a curtain blocking mechanism, which includes a curtain frame, a cover plate and a curtain blocking mechanism. The curtain blocking mechanism is mounted on the cover plate, and the cover plate is detachably mounted on the curtain frame.

[0009] In the above technical solution, the four sides of the cover plate are folded outwards, and a U-shaped slot is provided at the cover plate installation position on the curtain frame. The four sides of the cover plate are clamped in the U-shaped slot and are sealed to the curtain frame.

[0010] In order to achieve the above-mentioned purpose, the second technical solution of the present utility model is: a feeding mechanism of a shot blasting machine, comprising the above-mentioned feeding sealing chamber, a shot roller is provided at one end of the feeding sealing chamber, a feeding conveyor belt is provided at the other end of the feeding sealing chamber, the vibrating conveyor extends into the feeding sealing chamber, and a third maze structure is provided on the outer periphery of the connection between the shot roller and the feeding sealing chamber, and the third maze structure is a ring-shaped baffle.

[0011] In the above technical solution, a shot collecting trough is provided at the lower portion of the vibrating conveyor, and a plurality of shot baffles are provided in the shot collecting trough.

[0013] In the above technical solution, both sides of the curtain frame are softly connected with rubber side plates, and the lower ends of the rubber side plates are installed on the vibrating conveyor.

[0014] In summary, the technical solution of the present invention has the following beneficial effects compared to traditional technical means: the connection between the feed sealing chamber and the roller of the present invention adopts a multi-layered maze structure. The first layer of the maze structure is located on the end face of the roller, in the roller connection chamber in front of the rolling end, to initially block the rebounding shot. The second layer of the maze is located at the notch of the lower chute chamber to prevent the falling shot from being ejected outward. The third layer of the maze is located on the outer surface of the roller to block the rebounding steel shot, and a rubber sheet is used to "scrape" off the steel shot remaining on the outer surface of the roller. The multi-layered maze structure blocks the steel shot, effectively absorbing the kinetic energy of the shot and preventing it from being ejected. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The following is based on the ideal embodiment of the present invention. Through the following description, relevant personnel can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the content of the specification, but must be determined according to the scope of the claims.

[0023] The present invention will be further described with reference to the following drawings:

[0024] like Figures 1 to 5 As shown, a shot blasting machine feeding sealing chamber 100 includes an energy absorption chamber 110 and a roller connecting chamber 120, a lower chute chamber 130 is provided at the lower part of the roller connecting chamber 120, and a first maze structure 140 is provided at the side where the roller connecting chamber 120 is connected to the shot roller 200. The first maze structure 140 is an annular baffle arranged on the inner side of the roller connecting chamber 120, and a second maze body 150 is provided on the outside of the lower chute chamber 130, and the second maze body 150 is a baffle arranged at the mouth of the lower chute chamber 130.

[0025] A detection mechanism 160 is provided at the feed port on one side of the drum connecting chamber 120, and the detection mechanism 160 includes a detection frame 161, a rigid plate 162 and a shooting switch 163. The detection frame 161 is installed on the energy absorption chamber 110, and the rigid plate 162 is hinged on the detection frame 161. The shooting switch 163 is arranged on both sides of the rigid plate 162. When material 400 moves along with the vibrating conveyor 300 and is about to enter the shot blasting machine, the material 400 touches the rigid plate 162 on the incoming material detection mechanism 160, and the rigid plate 162 rotates. After receiving the signal, the shooting switch 163 sends it to the shot blasting machine system, and the shot blasting machine shot valve is delayed to open; when there is no material for a period of time, the shot blasting machine system loses the shooting switch signal, the shot blasting machine shot valve is delayed to close the shot valve, and the shot blasting machine stops, which can reduce power loss, delay the wear of wearing parts, and also reduce the occurrence of steel shot leakage.

[0026] The baffles of the first labyrinth structure 140 and the second labyrinth body 150 are both rubber baffles, and are rectangular or crescent-shaped.

[0027] like Figure 1 、 2 As shown, the energy absorbing chamber 110 and the roller connecting chamber 120 are both provided with a curtain blocking mechanism 170 , and the curtain blocking mechanism 170 includes a curtain frame 171 , a cover plate 172 and a curtain blocking 173 . The curtain blocking is mounted on the cover plate, and the cover plate 172 is detachably mounted on the curtain frame 171 .

[0028] The energy absorbing chamber 110 is provided with eight curtain blocking mechanisms 170 , and the roller connecting chamber 120 is provided with two curtain blocking mechanisms 170 .

[0029] The four sides of the cover plate 172 are folded outwards, and a U-shaped slot is provided at the installation position of the cover plate 172 on the curtain frame 171. The four sides of the cover plate 172 are clamped in the U-shaped slot and are sealed to the curtain frame 171.

[0030] Since these curtains 173 face the impact of steel shots head-on, they are very easy to wear out after long-term use and need regular maintenance and replacement. In order to facilitate later inspection and replacement, the rubber curtains 173 are innovatively designed to be disassembled and assembled from the outside. The rubber curtains 173 can be pulled out by simply pulling up the movable cover 172 that fixes the rubber curtains 173 from the outside. There is no need for maintenance personnel to drill into a closed and narrow space, which reduces work intensity and improves work efficiency.

[0031] Example 2:

[0032] like Figure 2 、 3As shown, a feeding mechanism of a shot blasting machine includes the feeding sealing chamber 100 described in Example 1, a shot roller 200 is provided at one end of the feeding sealing chamber 100, and a vibrating conveyor 300 is provided at the other end of the feeding sealing chamber 100, and the vibrating conveyor 300 extends into the feeding sealing chamber 100, and a third maze structure 210 is provided on the outer periphery of the connection between the shot roller 200 and the feeding sealing chamber 100, and the third maze structure 210 is an annular baffle.

[0033] A shot collecting trough 310 is provided at the lower portion of the vibrating conveyor 300 , and a plurality of shot baffles 311 are provided in the shot collecting trough.

[0034] A shot chute 312 is provided at the lower portion of the shot collecting trough 310 , and the shot collecting trough 310 is used to recover a very small amount of shot that escapes. The shot collected by the shot collecting trough 310 will flow back to the steel shot recovery system along the shot chute 312 .

[0035] Both sides of the curtain frame 171 are softly connected with rubber side plates, and the lower ends of the rubber side plates are installed on the vibrating conveyor 300 to prevent steel shots from escaping from the side gaps.

[0036] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
