Description

Technical Field

[0001] This utility model belongs to the technical field of screening devices, and more specifically, it relates to a vibrating screen screening device. Background Technology

[0002] In industrial production, screening devices are often used to screen materials into particles. For example, in the production process of various manufacturing workshops, workers often use screening equipment in order to obtain materials that meet specific particle size requirements. At this time, it is necessary to use a device that can meet the screening accuracy required for production to achieve effective screening of materials and facilitate the smooth progress of subsequent production processes.

[0003] In actual production, traditional screening devices, due to their single screening method, are difficult to further screen materials. As a result, if the particle size of the material does not meet the requirements, it is easy for defects to appear in the product under the action of subsequent processing steps, resulting in an increase in the product defect rate. This not only affects the market competitiveness of the product and causes economic losses to the enterprise, but also increases production costs due to the need for rework or scrapping of defective products, thereby reducing the enterprise's production efficiency and profitability.

[0004] Based on the existing technology, it was found that traditional screening devices are difficult to further screen materials, affecting product accuracy and causing an increase in product defect rate. Utility Model Content

[0028] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. Example

[0029] As attached Figure 1 To be continued Figure 4 As shown:

[0030] This utility model provides a vibrating screen screening device, including a frame 1, multiple sets of vibrating springs 2 are installed on the frame 1, each set of vibrating springs 2 is equipped with a mounting frame 3, a collection hopper 4 is installed between the multiple sets of mounting frames 3, a screening screen 5 is installed inside the collection hopper 4, and a discharge port is provided at the bottom of the collection hopper 4.

[0031] Please refer to, for example Figure 3 , Figure 4 and Figure 6 As shown, an upper port 6 is installed at the bottom of the discharge port. A feed pipe is installed at one end of the upper port 6, and a first fixed seat 7 is installed at the other end of the feed pipe. A collection bin 8 is installed at one end of the first fixed seat 7, and a second fixed seat 9 is installed at the other end of the collection bin 8. Bearings are installed inside both the first fixed seat 7 and the second fixed seat 9. Mounting seats 10 are installed on one side of both sets of bearings. Internal threads are provided inside the mounting seats 10. A screen cylinder 11 is installed between the two sets of mounting seats 10. Connecting seats are provided at both ends of the screen cylinder 11. External threads are provided on the connecting seats, and the external threads and internal threads rotate. The second fixed seat 9 is equipped with a motor seat, on which a first motor 12 is mounted. A rotating wheel 13 is mounted on the output shaft of the first motor 12, and the rotating wheel 13 is rubbed against one of the connecting seats. An angle α is formed between the central axis of the screen cylinder 11 and the central axis of the upper port 6, where α ∈ 100° to 130°. Due to the angle of 100° to 130° between the screen cylinder 11 and the upper port 6, the material can flow in an inclined direction after entering the screen cylinder 11 from the upper port 6. Combined with the rotation of the screen cylinder 11, the material is screened more thoroughly.

[0032] Please refer to, for example Figure 5As shown, a first movable seat 14 is installed inside the frame 1. One end of the first movable seat 14 is rotatably connected to a second movable seat 15. A second motor 16 is installed on the second movable seat 15. A rotating seat is provided on the second movable seat 15. A lead screw sleeve 17 is clamped at the bottom of the first movable seat 14. A fixed lead screw 18 passes through the lead screw sleeve 17. A fixed lead screw 18 is clamped inside the rotating seat. The user can rotate the fixed lead screw 18 to move the lead screw sleeve 17 and the first movable seat 14, adjust the position of the second motor 16, and change the tension of the belt, so that the rotation of the vibrating rod 19 is more stable.

[0033] Please refer to, for example Figure 2 As shown, the hopper 4 has two sets of vibrating channels, and vibrating rods 19 are inserted into the two sets of vibrating channels. Eccentric wheels 20 are installed at both ends of the vibrating rods 19. A dust cover 21 is installed on one side of the eccentric wheel 20. A pulley is installed on one end of the vibrating rod 19 and the output shaft of the second motor 16. The two sets of pulleys are connected by a belt. The user can drive the vibrating rods 19 to rotate through the second motor 16. The eccentric wheels 20 generate centrifugal force as the vibrating rods 19 rotate, causing the hopper 4 to vibrate. The screening screen 5 shakes accordingly, allowing the material to be separated on the screening screen 5.

[0034] A discharge rack 22 is installed on one side of the hopper 4. A first support leg 23 is provided at the bottom of the frame 1. A second support leg 24 is provided inside the first support leg 23. A rubber pad 25 is installed at the bottom of the second support leg 24. The height of the frame 1 can be adjusted by extending and retracting the second support leg 24 inside the first support leg 23. The user does not need to raise it additionally during installation.

[0035] A fixing frame 26 is installed at the bottom of the collection bin 8, and a sealing cover 27 is installed on the collection bin 8. Two sets of fixing brackets 28 are installed on the top of the fixing frame 26, and a first fixing seat 7 and a second fixing seat 9 are respectively installed in the two sets of fixing brackets 28. Users can remove the sealing cover 27 to clean the residual material in the collection bin 8, avoid mixing of materials from different batches, and improve the ease of cleaning of the device. The two sets of fixing brackets 28 on the fixing frame 26 can fix the first fixing seat 7 and the second fixing seat 9, ensuring that the screen cylinder 11 will not shift when it rotates.

[0036] The second fixed seat 9 is equipped with a discharge pipe 29 at one end, and a first collection bucket is installed at the bottom of the discharge pipe 29. The collection bin 8 is equipped with a second collection bucket at the bottom.

[0037] The specific usage and function of this embodiment are as follows:

[0038] When using the device, the second support leg 24 inside the first support leg 23 is stretched until the rubber pad 25 makes stable contact with the ground, ensuring that the frame 1 is placed stably. Rotating the fixed lead screw 18 moves the lead screw sleeve 17 and the first movable seat 14, adjusting the position of the second motor 16 to make the belt have the appropriate tension, ensuring that the vibration rod 19 rotates stably.

[0039] Pour the material to be screened into the collection hopper 4, start the second motor 16, and its output shaft drives the vibrating rod 19 to rotate through the belt. The eccentric wheels 20 at both ends of the vibrating rod 19 rotate to generate centrifugal force, causing the collection hopper 4 to vibrate under the support of the vibrating spring 2. The screening screen 5 shakes with the collection hopper 4, and the material is separated on the screening screen 5. The material on the screen is discharged through the discharge rack 22, and the material under the screen falls into the bottom discharge port through the screening screen 5.

[0040] The undersize material from the discharge port enters the screen cylinder 11 through the upper port 6. The first motor 12 is started, and the rotating wheel 13 drives the screen cylinder 11 to rotate through friction. Since the screen cylinder 11 and the upper port 6 form an angle of 100° to 130°, the material flows in an inclined direction and is further screened during rotation. Part of the material passes through the mesh of the screen cylinder 11 and enters the collection bin 8, eventually falling into the second collection bucket at the bottom; the other part falls into the first collection bucket through the discharge pipe 29.

[0041] If cleaning is required, remove the sealing cover 27 and clean the residual material in the collection bin 8; the first fixed seat 7 and the second fixed seat 9 can be stabilized by the fixed bracket 28 on the fixed frame 26 to prevent the screen cylinder 11 from shifting when rotating. The dust cover 21 can reduce dust entering the connection between the eccentric wheel 20 and the vibrating rod 19 and extend the service life of the components.

[0042] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
