Description

Technical Field

[0001] The utility model relates to the field of vibrating screen machines, in particular to a novel shock-type standard vibrating screen machine. Background Art

[0002] Vibrating screen machine is a commonly used screening equipment, mainly used for screening, grading and filtering of solid particles. Vibrating screen machine separates particles by vibrating the screen. It has the advantages of high screening efficiency, large processing capacity and simple operation. It is widely used in food processing, chemical industry, building materials, metallurgy, mining and other industries. Powder materials include powdered sugar, starch, some plastic powder, ceramic powder, etc.

[0003] The existing vibrating screen machine places a screening frame on the vibrating screen machine, then pours the material to be screened on the screening frame, and then starts the vibrating screen machine to vibrate the screening frame to screen the material. The current vibrating screen machine can only vibrate and screen the internal material, and does not have the function of knocking on the outer wall of the screening frame. When screening powder materials, the powder materials will be adsorbed inside the screening frame under the action of static electricity, thereby affecting the screening quality and making it inconvenient to clean up later.

[0004] Therefore, it is necessary to design a new type of shock-type standard vibrating screen machine that can knock on the outer wall of the screening frame to prevent the powder material from being adsorbed on the inner wall of the screening frame, improve the screening quality, and facilitate subsequent cleaning. Utility Model Content

[0005] In order to overcome the shortcomings of the current vibrating screening machine that can only vibrate and screen the internal materials but does not have the function of knocking on the outer wall of the screening frame, when screening powder materials, the powder materials will be adsorbed inside the screening frame under the action of static electricity, thereby affecting the screening quality and making it inconvenient for subsequent cleaning. The utility model provides a new type of vibration type standard vibrating screening machine which can knock on the outer wall of the screening frame to prevent the powder materials from being adsorbed on the inner wall of the screening frame, thereby improving the screening quality and facilitating subsequent cleaning.

[0006] Technical solution: A new type of shock-type standard vibrating screen machine, including a vibrating screen machine, a clamping piece, a screening frame, an adjusting screw and a stabilizing mechanism. The vibrating screen machine is slidably connected with a clamping piece, and multiple screening frames are placed in the middle of the vibrating screen machine. The clamping piece is in contact with the uppermost screening frame. Multiple adjusting screws are threadedly connected to the clamping piece, and the adjusting screws are in contact with the vibrating screen machine. The vibrating screen machine is provided with a stabilizing mechanism for knocking the outer wall of the screening frame.

[0007] As an improvement to the above solution, a handle is provided on the upper portion of the locking member.

[0008] As an improvement of the above solution, the sieve holes on the screening frame gradually become smaller from top to bottom.

[0009] As an improvement of the above scheme, the stabilizing mechanism includes a fixed block, a connecting frame, a rotating block, a torsion spring and an oscillating ball. A plurality of fixed blocks are evenly distributed on the upper part of the vibrating screen machine according to the circumference. The fixed blocks are connected to a connecting frame. A plurality of rotating blocks are rotatably connected to the connecting frame. The rotating blocks are all in contact with and cooperate with the screening frame at the same horizontal position. Two upper and lower torsion springs are connected between the rotating blocks and the connecting frame. Two oscillating balls are placed in the middle of the rotating blocks.

[0010] As an improvement of the above solution, the inner sides of the rotating blocks are all arc-shaped.

[0011] As an improvement of the above scheme, an auxiliary mechanism is also included, which includes a rotating ring and a pressure plate. A plurality of rotating rings are rotatably connected to the connecting frame, and a plurality of pressure plates are connected between the outer sides of the rotating rings. The pressure plates are in contact with and cooperate with adjacent rotating blocks.

[0012] Beneficial effects: 1. During the vibration process of the utility model, the powder material falls from the uppermost screening frame to the lowermost screening frame according to the different particle sizes. Under the action of centrifugal force, the oscillating ball will hit the rotating block, causing the rotating block to hit the outer wall of the screening frame, thereby knocking the outer wall of the screening frame to prevent the powder material from being adsorbed on the inner wall of the screening frame, thereby improving the quality of screening and facilitating later cleaning.

[0013] 2. The utility model rotates the rotating ring to make the pressure plate contact with the rotating block, so that the rotating block rotates and disengages from the screening frame, and the torsion spring is deformed. Then the adjusting screw is manually twisted to disengage from the vibrating screen, and then the positioning piece is pulled to disengage from the screening frame, so that the screening frame can be removed. The operation is simple, the screening frame is easy to install and remove, and the convenience of using the device is improved. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] A new type of standard vibrating screen machine, such as Figure 1-Figure 4 As shown, it includes a vibrating screen machine 1, a retaining member 2, a screening frame 3, an adjusting screw 4 and a stabilizing mechanism 5. The vibrating screen machine 1 is slidably connected with the retaining member 2, and a handle is provided on the upper part of the retaining member 2 to facilitate the movement of the retaining member 2 by hand. Six screening frames 3 are placed in the middle of the vibrating screen machine 1. The retaining member 2 is in contact with the uppermost screening frame 3. The sieve holes on the screening frame 3 gradually become smaller from top to bottom. Three adjusting screws 4 are threadedly connected to the retaining member 2, and the adjusting screws 4 are all in contact with the vibrating screen machine 1. The vibrating screen machine 1 is provided with a stabilizing mechanism 5 for knocking the outer wall of the screening frame 3.

[0022] like Figure 1 , Figure 3 and Figure 4 As shown, the stabilizing mechanism 5 includes a fixed block 51, a connecting frame 52, a rotating block 53, a torsion spring 54 and an oscillating ball 55. Four fixed blocks 51 are evenly distributed on the upper part of the vibrating screen 1 according to the circumference. The fixed blocks 51 are connected to the connecting frame 52. Twenty-four rotating blocks 53 are rotatably connected to the connecting frame 52. The rotating blocks 53 are all in contact with the screening frame 3 at the same horizontal position. The inner sides of the rotating blocks 53 are all arc-shaped, which is convenient for fitting the shape of the screening frame 3. The rotating blocks 53 are connected to the connecting frame 52 with two upper and lower torsion springs 54, and two oscillating balls 55 are placed in the middle of the rotating blocks 53.

[0023] like Figure 1 and Figure 5 As shown, an auxiliary mechanism 6 is also included, which includes a rotating ring 61 and a pressure plate 62. Five rotating rings 61 are rotatably connected to the connecting frame 52, and four pressure plates 62 are connected between the outer sides of the rotating rings 61. The pressure plates 62 are all in contact and cooperate with adjacent rotating blocks 53.

[0024] When it is necessary to vibrate and screen the powder material, the device can be used and brought to the place where the powder material needs to be vibrated and screened, and the retaining piece 2 is moved to the uppermost side by the handle, and then the adjusting screw 4 is screwed to contact the vibrating screen machine 1 to fix the retaining piece 2, and then the rotating ring 61 is turned by hand, thereby driving the pressing plate 62 to rotate and contact the rotating block 53, so that the rotating block 53 rotates, the torsion spring 54 is deformed, and the inner side of the rotating block 53 is all arc-shaped, which is convenient for fitting the shape of the screening frame 3. Then the screening frame 3 can be placed on the vibrating screen machine 1, and the sieve holes on the screening frame 3 gradually become smaller from top to bottom, and then the powder material is poured on the uppermost screening frame 3, and then the adjusting screw 4 is screwed to pull the retaining piece 2 to move and contact the uppermost vibrating screen machine 1, and then the adjusting screw 4 is tightened to fix the retaining piece 2, and then the screening frame 3 is fixed, and the rotating ring 61 is loosened, the torsion spring 54 rotates to restore, and the rotating ring 61 moves to reset, so that the rotating block 53 contacts with the screening frame 3, and then the vibrating screen machine 1 is started to vibrate the screening frame 3 through the vibrating screen machine 1. During the vibration process, the powder material falls from the uppermost screening frame 3 to the lowermost screening frame 3 according to the different particle sizes. Under the action of centrifugal force, the oscillating ball 55 will knock the rotating block 53, so that the rotating block 53 knocks the outer wall of the screening frame 3, thereby being able to knock the outer wall of the screening frame 3 to prevent the powder material from being adsorbed on the inner wall of the screening frame 3, thereby improving the quality of screening and facilitating later cleaning. After the screening is completed, by rotating the rotating ring 61, the pressing plate 62 contacts with the rotating block 53, so that the rotating block 53 rotates and disengages from the screening frame 3, and the torsion spring 54 is deformed. Then the adjusting screw 4 is manually twisted to disengage from the vibrating screen machine 1, and then the retaining piece 2 is pulled to disengage from the screening frame 3, so that the screening frame 3 can be removed. The operation is simple, which is convenient for loading and unloading the screening frame 3, and the convenience of using the device is improved. Then the powder material in the screening frame 3 can be poured out.
