Description

Technical Field

[0001] The utility model relates to the technical field of shot blasting machines, in particular to a double-layer cross-sand leakage mesh plate of a shot blasting machine. Background Art

[0002] Shot blasting is a surface finishing process that uses a shot blasting machine as the process equipment, and selects steel shots or other shot materials selected for the process, and impacts the surface of the workpiece at the required speed. Its main purpose is to remove impurities on the workpiece surface or strengthen the workpiece surface, such as to obtain a clean surface with a specified roughness, to meet the requirements of subsequent processes such as spraying. The shot blasting machine is a process equipment that achieves, for example, the acceleration and orientation of the steel shots. When the steel shot enters the shot blasting machine, it will gain a certain amount of kinetic energy under the action of centrifugal force, and then fly out at a high speed according to a predetermined exit angle, rushing towards the surface of the workpiece. However, the steel shot can easily damage the internal wall panels of the shot blasting machine and has a certain destructive power. Therefore, a guard plate will be set on the inner wall of the shot blasting machine, and the impacted steel shot will be recovered. Generally, it will be concentrated in a conical recovery bin, and a mesh plate will often be set on the recovery bin to cushion the impact of the steel shot. During the impact of the steel shot, since the through hole on the mesh plate is just facing the opening of the conical bin, when the steel shot falls out from the through hole of the mesh plate, it will directly hit the opening of the conical bin, causing the opening of the conical bin to be damaged. For this reason, we proposed a double-layer cross-sand leakage mesh plate for a shot blasting machine. Utility Model Content

[0003] The utility model provides a double-layer cross-sand leakage mesh plate of a shot blasting machine, which solves the problems raised by the above background technology.

[0005] Optionally, the upper surface of the upper buffer plate is provided with a plurality of downwardly concave arc-shaped grooves, the arc-shaped grooves are upwardly protruding arcs, and the entrance is arranged on the horizontal center line of the bottom of the arc-shaped groove.

[0006] Optionally, there is an upwardly protruding arc between the entrance openings formed on the arc-shaped groove, and the bottom end of the arc is opposite to the entrance opening.

[0007] Optionally, a plurality of evenly distributed guide blocks are fixedly connected to the upper surface of the lower buffer plate, and the guide blocks are located between the outlets and directly below the inlet.

[0008] Optionally, the guide block is semicircular, the top of the guide block and the center of the inlet are on the same vertical center line, and an arc surface leading to the outlet is formed between the guide block and the outlet.

[0010] The utility model has the following beneficial effects:

[0011] 1. The double-layer cross-sand leakage mesh plate of the shot blasting machine allows the steel shot to enter the buffer space through the entrance, and under the action of the outlet staggered with the entrance, the steel shot entering the buffer space can be briefly detained on the lower buffer plate before passing through the entrance, buffering the steel shot that directly passes through the entrance, and then falls through the outlet, effectively reducing the impact of the steel shot on the conical bin, thereby better protecting it.

[0012] 2. The double-layer cross-sand leakage mesh plate of the shot blasting machine, guided by the arc-shaped groove and the upward protruding arc structure between the entrance, allows the steel balls to enter the buffer space more smoothly, reducing the steel balls retained on the upper buffer plate, and under the guidance of the guide block, the steel balls can be more smoothly raised to the outlet, thereby making the circulation of the steel balls smoother.

[0013] 3. The double-layer cross-sand leakage mesh plate of the shot blasting machine has a better support effect by improving the continuous arc structure of the vertical support frame and the horizontal support frame, and improves the vertical support frame and the horizontal support frame to provide multi-point support for the upper buffer plate, thereby effectively reducing the stability of the upper buffer plate and avoiding the upper buffer plate from being easily deformed, thereby making the buffering effect of the upper buffer plate better.

The inlet 3 and the outlet 5 are staggered and the vertical center lines of the two do not coincide. The steel shots are buffered by the upper buffer plate 1, and the steel shots that directly pass through the inlet 3 will not directly pass through the outlet 5 under the action of the staggered outlets 5, but will first contact the lower buffer plate 4 and then fall through the outlet 5, which can relatively comprehensively buffer the steel shots and prevent the steel shots from directly impacting the collection bin and causing damage to it.

[0022] See also Figures 1 to 4 The upper surface of the upper buffer plate 1 is provided with a plurality of downwardly concave arc-shaped grooves 2, and the arc-shaped grooves 2 are upwardly protruding arcs, so that the steel shots falling on the upper buffer plate 1 can be smoothly guided into the arc-shaped grooves 2, and under the action of the arc-shaped structure of the arc-shaped grooves 2, the arc-shaped grooves 2 can smoothly guide the steel shots into the inlet 3, and the inlet 3 is arranged on the horizontal center line of the bottom of the arc-shaped grooves 2.

[0023] See also Figures 1 to 4There is an upward protruding arc between the entrance 3 opened on the arc-shaped groove 2, and the bottom end of the arc is opposite to the entrance 3, so that the steel shots in the arc-shaped groove 2 can be smoothly guided into the entrance 3, so that the steel shots can smoothly flow into the buffer space to reduce the steel shots retained on the upper buffer plate 1.

[0024] See also Figures 1 to 5 A plurality of evenly distributed guide blocks 6 are fixedly connected to the upper surface of the lower buffer plate 4. The guide blocks 6 are located between the outlets 5 and directly below the inlet 3, thereby guiding the steel mesh passing through the inlet 3.

[0025] See also Figures 1 to 5 The guide block 6 is semicircular, and the top of the guide block 6 is on the same vertical center line as the center of the inlet 3, and an arc surface guiding to the outlet 5 is formed between the guide block 6 and the outlet 5, so that the steel shots falling into the buffer space can flow smoothly to the outlet 5, so that the steel shots can flow out of the buffer space smoothly, thereby reducing the steel shots retained in the buffer space.

[0026] See also Figures 1 to 5 , a plurality of horizontal vertical support frames 7 and longitudinal horizontal support frames 8 are arranged in the buffer space, and the vertical support frames 7 and the horizontal support frames 8 are in a continuous arc structure, which makes the support effect better, and the vertical support frames 7 and the horizontal support frames 8 are overlapped and fixed, and the arc vertices of the top ends of the vertical support frames 7 and the horizontal support frames 8 are fixed to the lower surface of the arc-shaped groove 2 and do not coincide with the entrance 3, and the arc vertices of the bottom ends of the vertical support frames 7 and the horizontal support frames 8 are fixed to the upper surface of the lower buffer plate 4 and do not coincide with the outlet 5. The vertical support frames 7 and the horizontal support frames 8 can support the upper buffer plate 1 at multiple points to prevent the upper buffer plate 1 from being deformed by the impact of steel shots, thereby better protecting the upper buffer plate 1.

[0027] In summary, when the double-layer cross-sand mesh plate of the shot blasting machine is in use, the steel shots fall onto the upper buffer plate 1, and under the action of the structure on the upper buffer plate 1, the steel shots can roll into the arc-shaped groove 2, and under the guidance of the upward protruding arc structure between the inlets 3, the steel shots in the arc-shaped groove 2 can smoothly roll into the inlet 3, and the steel shots pass through the inlet 3 into the buffer space, and under the action of the staggered inlet 3 and outlet 5, the steel shots can first fall onto the lower buffer plate 4, and then under the guidance of the guide block 6, the steel shots on the lower buffer plate 4 can flow to the outlet 5, and then fall through the outlet 5 for reflux collection.
