Description

Technical Field

[0001] This utility model relates to the field of screening device technology, specifically a screening device for processing. Background Technology

[0002] Screening is a process that uses a sieve to allow fine particles smaller than the sieve openings to pass through the sieve surface, while coarse particles larger than the sieve openings remain on the sieve surface, thus completing the separation of coarse and fine materials.

[0003] According to CN217911388U, a purification and screening device for edible fungi processing includes a filter box and multiple screens disposed inside the filter box. A feeding assembly for uniformly conveying edible fungi into the filter box is provided at the top of the filter box. The multiple screens are staggered inside the filter box via snap-fit ​​assemblies. A first discharge port is provided at the bottom of the filter box. The snap-fit ​​assembly includes an installation groove on the inner wall of the filter box. A matching locking block is connected to one end of each screen near the installation groove. Guide plates connected to the inner wall of the filter box are provided below each screen. A second discharge port is provided on the filter box at the position where the guide plates connect to the inner wall of the filter box. A door is hinged to one side of the filter box. A dust collection assembly for cleaning generated dust is provided on the filter box. The snap-fit ​​assemblies facilitate the disassembly and replacement of the screens, improving the applicability of the device.

[0004] The aforementioned snap-fit ​​assembly facilitates the disassembly and replacement of the screen. However, once the screen is installed in the snap-fit ​​assembly, its position is fixed. Although the material can move down along the screen's angle of inclination, some material may get stuck in the screen's mesh, thus affecting the screening of the material. Summary of the Invention

[0005] The purpose of this invention is to provide a screening device for processing, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a screening device for processing, comprising an outer shell, two guide grooves symmetrically opened on the front and rear sides of the outer shell, a movable plate slidably connected inside each of the two guide grooves, a motor fixedly mounted on one side of the outer shell, a turntable fixedly sleeved on the output shaft of the motor, an eccentric column fixedly mounted on the side of the turntable away from the motor, a first rotating plate rotatably connected to the surface of the eccentric column, a second rotating plate rotatably connected to the side of the first rotating plate away from the eccentric column, a connecting rod rotatably connected to the side of the second rotating plate away from the first rotating plate, and the connecting rod being fixedly connected to the movable plate near the motor.

[0007] As a further preferred embodiment of this technical solution, a sieve box is provided inside the outer shell. The sieve box is fixedly installed between two movable plates. Positioning grooves are symmetrically opened on the left and right sides of the sieve box, and two upper protrusions are symmetrically arranged on the bottom of the sieve box.

[0008] As a further preferred embodiment of this technical solution, the screen box is provided with a screen mesh inside, and two mounting slots are symmetrically opened on the left and right sides of the screen mesh. A first spring is fixedly installed on the inner wall of each of the two mounting slots. A positioning block is fixedly installed at the end of the first spring away from the screen mesh. The positioning block passes through the mounting slot and is engaged inside the positioning slot.

[0009] As a further preferred embodiment of this technical solution, two connecting frames are symmetrically arranged on the inner wall of the outer shell. A sliding groove is opened in the middle of each of the two connecting frames. A slider is slidably connected inside the sliding groove. A pad is fixedly arranged at the end of the slider away from the connecting frame. A second spring is fixedly arranged between the pad and the connecting frame. A lower protrusion is fixedly arranged at the top end of the pad. A top rod is fixedly arranged on the side of the top of the pad away from the lower protrusion.

[0010] As a further preferred embodiment of this technical solution, the connecting frame adopts an L-shaped structure, the lower protrusion and the upper protrusion are located in the same plane, and both sides of the lower protrusion are set as arc surfaces.

[0013] This utility model provides a screening device for processing, which has the following beneficial effects:

[0014] (1) By starting the motor, the output shaft of the motor drives the turntable to rotate. Since the eccentric column is off the center of the turntable, the eccentric column drives the first rotating plate and the second rotating plate to rotate along with the turntable. The second rotating plate pulls the connecting rod and the moving plate to slide back and forth in the guide groove, so that the screen box shakes inside the outer shell to speed up the screening efficiency and prevent the material from staying on the screen.

[0015] (2) In this utility model, during the reciprocating movement of the screen, the upper protrusion moves accordingly. After moving a certain distance, the upper protrusion and the lower protrusion come into contact and slide relative to each other through the arc surface of the contact. The second spring is squeezed and contracted, and the slider and the pad drive the top rod to move down. After the upper protrusion and the lower protrusion separate, the second spring rebounds and causes the pad to drive the top rod to move up. The top rod comes into contact with the screen and causes the screen to vibrate, thereby causing the particles stuck in the screen mesh to detach, so as to ensure the normal operation of the screen.

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figures 1 to 6As shown, in this embodiment, a screening device for processing includes an outer shell 1. Two guide grooves 2 are symmetrically opened on the front and rear sides of the outer shell 1. A movable plate 3 is slidably connected inside each of the two guide grooves 2. A motor 4 is fixedly installed on one side of the outer shell 1. A turntable 5 is fixedly sleeved on the output shaft of the motor 4. An eccentric column 6 is fixedly installed on the side of the turntable 5 away from the motor 4. A first rotating plate 7 is rotatably connected to the surface of the eccentric column 6. A second rotating plate 8 is rotatably connected to the side of the first rotating plate 7 away from the eccentric column 6. A connecting rod 9 is rotatably connected to the side of the second rotating plate 8 away from the first rotating plate 7. The connecting rod 9 is fixedly connected to the movable plate 3 on the side close to the motor 4.

[0025] When the motor 4 is started, its output shaft drives the turntable 5 to rotate. Since the eccentric column 6 is off-center from the turntable 5, the eccentric column 6 drives the first rotating plate 7 and the second rotating plate 8 to rotate along with the turntable 5. The second rotating plate 8 pulls the connecting rod 9 and the moving plate 3 to slide back and forth inside the guide groove 2. The screen box 10 shakes inside the outer shell 1, so that the material is spread flat on the screen 12, avoiding excessive feeding and blockage, thereby speeding up the screening efficiency. The size of the screen box 10 can ensure that it is always in an excessive state during the reciprocating shaking process, preventing the material from falling out of the screen box 10 when the screen 12 is working.

[0026] The outer casing 1 has a screen box 10 inside, which is fixedly installed between two movable plates 3. Positioning grooves 11 are symmetrically opened on the left and right sides of the screen box 10, and two upper protrusions 16 are symmetrically arranged on the bottom of the screen box 10.

[0027] The screen box 10 is equipped with a screen 12. Two mounting slots 13 are symmetrically opened on the left and right sides of the screen 12. A first spring 14 is fixedly installed on the inner wall of each mounting slot 13. A positioning block 15 is fixedly installed at the end of the first spring 14 away from the screen 12. The positioning block 15 passes through the mounting slot 13 and is engaged inside the positioning slot 11.

[0028] The screen 12 is placed inside the screen box 10, and the positioning block 15 is moved into the mounting groove 13. The first spring 14 is compressed and contracted. After moving down a certain height, the positioning block 15 corresponds to the position of the positioning groove 11. The first spring 14 rebounds and pushes the positioning block 15 to engage in the positioning groove 11, thereby fixing the screen 12 inside the screen box 10, so as to improve the convenience of installing and disassembling the screen 12.

[0029] Two connecting brackets 17 are symmetrically arranged on the inner wall of the outer shell 1. Each connecting bracket 17 has a groove 18 in the middle. A slider 19 is slidably connected inside the groove 18. A pad 21 is fixedly arranged at the end of the slider 19 away from the connecting bracket 17. A second spring 20 is fixedly arranged between the pad 21 and the connecting bracket 17. A lower protrusion 22 is fixedly arranged at the top end of the pad 21. A top rod 23 is fixedly arranged on the side of the top of the pad 21 away from the lower protrusion 22.

[0030] During the reciprocating movement of the screen 12, the upper protrusion 16 moves accordingly. After moving a certain distance, the upper protrusion 16 and the lower protrusion 22 come into contact and slide relative to each other through the arc surface of the contact. The second spring 20 is squeezed and contracted, and the slider 19 and the pad 21 drive the top rod 23 to move down. After the upper protrusion 16 and the lower protrusion 22 separate, the second spring 20 rebounds and causes the pad 21 to drive the top rod 23 to move up. The top rod 23 comes into contact with the screen 12 and causes the screen 12 to vibrate, thereby causing the particles stuck in the mesh of the screen 12 to detach, so as to ensure the normal operation of the screen 12.

[0031] The connecting frame 17 adopts an L-shaped structure, with the lower protrusion 22 and the upper protrusion 16 located in the same plane, and both sides of the lower protrusion 22 are set as arc surfaces.

[0032] A collection pipe 24 is fixedly installed on the side of the outer casing 1 away from the motor 4. A partition net 25 is provided between the collection pipe 24 and the outer casing 1. A connecting pipe 26 is fixedly installed at the end of the collection pipe 24 away from the partition net 25.

[0033] A dust collection box 27 is fixedly installed on the side of the outer casing 1 away from the connecting rod 9. The dust collection box 27 and the end of the connecting pipe 26 away from the collecting pipe 24 are fixedly connected. A fan 28 is fixedly installed on the side of the dust collection box 27 near the motor 4. A filter screen 29 is slidably connected inside the dust collection box 27. The filter screen 29 is located between the connecting pipe 26 and the fan 28.

[0034] The fan 28 is started to create a negative pressure suction at the collection pipe 24, thereby collecting the dust generated during the material screening process into the connecting pipe 26 and transporting it into the dust collection box 27. The dust is then captured and collected by the filter screen 29. A partition screen 25 is provided at the outer shell 1 and the collection pipe 24 to prevent lighter materials from entering the collection pipe 24.

[0035] This utility model provides a screening device for processing, the specific working principle of which is as follows:

[0036] In use, the screen 12 is placed inside the screen box 10, and the positioning block 15 is moved into the mounting groove 13. The first spring 14 is compressed and contracted. After moving down a certain height, the positioning block 15 corresponds to the position of the positioning groove 11. The first spring 14 rebounds and pushes the positioning block 15 to engage in the positioning groove 11, thereby fixing the screen 12 inside the screen box 10. The material is put into the outer shell 1 through the feed port at the top of the outer shell 1 and falls onto the screen 12. At this time, the motor 4 is started, and its output shaft drives the turntable 5 to rotate. Since the eccentric column 6 is off-center from the turntable 5, the eccentric column 6 drives the first rotating plate 7 and the second rotating plate 8 to rotate with the turntable 5. The second rotating plate 8 pulls the connecting rod 9 and the moving plate 3 to slide back and forth inside the guide groove 2. The screen box 10 shakes inside the outer shell 1, thereby using the screen 12 to separate the material and particles, and realize the screening of the material.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
