Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of toner processing equipment, and in particular relates to an automatic screening system for a toner production line. Background Technology
[0002] Toner, also known as carbon powder, is a powdery substance used in laser printers to image and fix images on paper. Black toner is composed of binder resin, carbon black, charge control agent, and additives. Color toner also requires the addition of other color pigments. In the toner processing production line, the raw materials are first pre-crushed and then screened.
[0003] Currently, most toner screening methods involve screening using grading screening machines. However, after being crushed, toner forms relatively fine particles that float in the working environment and are discharged through the ventilation system, causing environmental pollution. Furthermore, collection is very difficult and can easily lead to resource waste.
[0004] To address these issues, we provide an automated screening system for toner production lines. Utility Model Content
[0005] The purpose of this invention is to provide an automatic screening system for toner production lines. By combining the filter components and the ventilation components, it solves the problem that existing toner screening machines lack the function of collecting floating particles, and smaller particles are easily discharged with the exhaust system, resulting in resource waste.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model is an automatic screening system for a toner production line, including a screening box, a screening plate movably connected inside the screening box, a vibration motor installed at the bottom of the screening plate, and a filter shell connected to the top of the screening box.

A transmission rod is movably connected inside the screening cylinder, and a cleaning brush plate is fixedly connected to the surface of the transmission rod.
[0009] The top of the filter housing is provided with a ventilation component, which includes a drive motor. The drive motor is installed on the top of the screening cylinder, and the top of the screening cylinder is connected to an exhaust pipe.
[0010] The present invention is further configured such that the ventilation component includes a movable rod, the movable rod is movably connected to the inside of the exhaust pipe, a fan blade is fixedly connected to the surface of the movable rod and located inside the exhaust pipe, and one end of the movable rod extends through to the outside of the exhaust pipe and is fixedly connected to a first bevel gear.
[0011] The present invention is further configured such that the top of the transmission rod passes through the exhaust pipe and is fixedly connected to the output end of the drive motor, and the surface of the transmission rod is movably connected to the inner wall of the filter shell through a bearing.
[0012] The present invention is further configured such that a second bevel gear is fixedly connected to the surface of the transmission rod, and the bottom of the first bevel gear meshes with the second bevel gear.
[0013] The present invention is further configured such that a first collection box is connected to one side of the screening box, a spring is fixedly connected inside the first collection box, and the other end of the spring is fixedly connected to the screening plate.
[0014] The present invention is further configured such that a second collection box is connected to the other side of the screening box, and a feed pipe is connected to the front side of the filter shell.

[0027] The technical solutions of the present invention will be described below with reference to the accompanying drawings of the embodiments of the present invention. The described embodiments are only some embodiments of the present invention, and not all embodiments. Specific Implementation
[0028] Please see Figure 1-5 This utility model is an automatic screening system for a toner production line, including a screening box 1, a screening plate 2 movably connected inside the screening box 1, a vibration motor 3 installed at the bottom of the screening plate 2, and a filter shell 4 connected to the top of the screening box 1; a filter assembly is provided on the top of the screening box 1, the filter assembly includes a screening cylinder 5, the screening cylinder 5 is installed inside the filter shell 4, a transmission rod 6 is movably connected inside the screening cylinder 5, and a cleaning brush plate 7 is fixedly connected to the surface of the transmission rod 6; a ventilation assembly is provided on the top of the filter shell 4, the ventilation assembly includes a drive motor 8, the drive motor 8 is installed on the top of the screening cylinder 5, and an exhaust pipe 9 is connected to the top of the screening cylinder 5.
[0029] Specifically: one side of the screening plate 2 is movably connected to the inner wall of the screening box 1 via a pin, and the other side of the screening plate 2 extends into the first collection box 14. The screening plate 2 consists of a frame and a screening mesh. When the powder falls into the screening plate 2, large particles of powder are blocked through the screening holes inside the screening mesh, thus achieving the screening function. The screening cylinder 5 is conical and its surface is made of metal filter mesh, which can filter and collect the powder that is thrown up. The cleaning brush 7 is in contact with the surface of the screening cylinder 5 and can clean the powder accumulated on the surface of the screening cylinder 5 when the cleaning brush 7 rotates. Specific Implementation
[0030] Please see Figure 1-5Based on the first specific embodiment, the ventilation assembly further includes a movable rod 10, which is movably connected to the inside of the exhaust pipe 9. A fan blade 11 is fixedly connected to the surface of the movable rod 10 and inside the exhaust pipe 9. One end of the movable rod 10 extends through to the outside of the exhaust pipe 9 and is fixedly connected to a first bevel gear 12. The top of the transmission rod 6 extends through the exhaust pipe 9 and is fixedly connected to the output end of the drive motor 8. The surface of the transmission rod 6 is movably connected to the inner wall of the filter housing 4 via a bearing. A second bevel gear 13 is fixedly connected to the surface of the transmission rod 6. The bottom of the bevel gear 12 meshes with the second bevel gear 13. The first collection box 14 is connected to one side of the screening box 1. A spring 15 is fixedly connected inside the first collection box 14. The other end of the spring 15 is fixedly connected to the screening plate 2. The second collection box 16 is connected to the other side of the screening box 1. The feed pipe 17 is connected to the front of the filter shell 4. The discharge pipes 18 are connected to both sides of the filter shell 4. The bottom of the discharge pipe 18 is connected to the collection bucket 19. The guide cylinder 20 is fixedly connected inside the screening cylinder 5. The top of the guide cylinder 20 has a ventilation opening 21.
[0031] Specifically: the fan blade 11 can rotate with the movable rod 10. When the fan blade 11 rotates, it can drive the air flow inside the exhaust pipe 9. An air inlet is opened on the front side of the screening box 1 so that external air can flow in. The gear ratio of the second bevel gear 13 to the first bevel gear 12 is 6:1. When the second bevel gear 13 drives the first bevel gear 12 to rotate, the rotation speed of the fan blade 11 can be increased. The spring 15 can stretch the screening plate 2 to increase the vibration effect. The discharge pipe 18 can discharge the cleaned powder. The inside of the guide cylinder 20 is conical, which can concentrate the raised powder through the ventilation port 21 and guide the powder into the discharge pipe 18 when the powder falls cleanly.
[0032] The working principle of this utility model is as follows: the staff discharges the toner raw material into the screening box 1 through the feed pipe 17, and screens the toner through the screening plate 2. Then, the vibration motor 3 is started by the external controller, and the vibration motor 3 transmits the vibration to the screening plate 2. The screening effect of the toner is increased by high-frequency vibration.
[0033] When fine powder is thrown up during the screening process, the drive motor 8 can be started. The drive motor 8, together with the transmission rod 6, drives the second bevel gear 13 to rotate. The second bevel gear 13, together with the first bevel gear 12, drives the movable rod 10 to rotate. The movable rod 10 drives the fan blade 11 to rotate. The fan blade 11 drives the air inside the filter shell 4 to flow. When the air flows upward, it drives the powder to contact the screening cylinder 5. The floating powder is filtered and collected by the screening cylinder 5.
[0034] As the transmission rod 6 rotates, it drives the cleaning brush plate 7 to rotate. The cleaning brush plate 7 cleans the powder accumulated on the surface of the screening cylinder 5. The accumulated powder particles are relatively large and will fall after cleaning. The powder is guided into the discharge pipe 18 through the guide cylinder 20 for centralized collection, which improves the collection and utilization rate of carbon powder and reduces pollution to the working environment.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through the control unit.
