Description

Technical Field

[0001] The utility model relates to the technical field of toner feeding, in particular to a toner feeding device with an anti-blocking structure. Background Art

[0002] Toner is the powdered substance used in laser printers to create images on paper. Black toner is composed of a binder resin, carbon black, a charge control agent, and external additives. Large quantities of toner are currently required in many industries, necessitating a toner feeder.

[0003] Currently, a Chinese patent discloses a combined graphite slag powder feeding system with the publication number CN111392442B. In the disclosed technical solution, the toner falls from the discharge barrel into the feed barrel, and two sets of symmetrically installed feeding devices can be exchanged by sliding the slide seat to complete the feeding.

[0004] According to the above-mentioned existing technical solutions, during the toner feeding process, the toner is easily adhered to the inner wall of the feeder due to the too fast feeding speed, which will cause the discharge pipe to be blocked, resulting in poor discharge of the material from the discharge port. The feeder needs to be stopped to clear the discharge pipe, which greatly reduces the utilization efficiency. Therefore, it does not meet the existing needs. In this regard, we propose a toner feeding device with an anti-blocking structure. Utility Model Content

The bottom of the second connecting block 15 is fixedly connected to the support shaft 22, and the surface of the support shaft 22 is fixedly connected to the fixed plate 16. The bottom of the fixed plate 16 is provided with a cam 13 rotatably connected to the outside of the support shaft 22, and the surface of the cam 13 is fixedly connected to the dial plate 14. A third reset spring 19 is connected between one side of the fixed plate 16 and one end of the dial plate 14, and the dial plate 14 completes the deflection and reset movement through the third spring 19.

[0024] The surface of the gear ring 4 meshes with one side of the gear 10. Scrapers 7 are fixedly connected to both sides of the inner wall of the gear ring 4. The surfaces of the scrapers 7 abut against the inner walls of the feeding hopper 3 and the feeding pipe 5 respectively to clear the toner adhering to the inner walls of the feeding hopper 3 and the feeding pipe 5. The scraper 7 includes a vertical plate end and an inclined plate end. The surface of the vertical plate abuts against the inner wall of the feeding hopper 3, and the surface of the inclined plate abuts against the inner wall of the feeding pipe 5. The bottom of the gear ring 4 is fixedly connected with abutment columns 6 at equal intervals. The surface of the abutment columns 6 abuts against the surface of the dial plate 14. The length of the dial plate 14 is just inserted into the gap between the pillars 6, so that the dial plate 14 is continuously dialed. The bottom of the gear ring 4 is rotatably connected to the feed pipe 5, and the top of the gear ring 4 is rotatably connected to the feeding hopper 3. The bottom of the feed pipe 5 is fixedly connected to the discharge pipe 2, and the surface of the discharge pipe 2 is fixedly connected with the first return spring 21 at equal intervals. The material of the discharge pipe 2 is relatively thin stainless steel. One end of the first return spring 21 is connected to the inner wall of the circular hole, and the first return spring 21 is used to better shake the discharge pipe 2.

[0025] One end of the knocking rod 11 abuts against the surface of the discharge pipe 2, and the impact end of the knocking rod 11 is made of soft rubber material. The outer side of the knocking rod 11 is sleeved with a trapezoidal block 12, and the surface of the trapezoidal block 12 abuts against the cam 13, and the other end of the knocking rod 11 is fixedly connected with a baffle 18, and the outer side of the knocking rod 11 is sleeved with a limit plate 17, and one side of the limit plate 17 is fixedly connected to one side of the base 1, and the outer side of the knocking rod 11 is sleeved with a second return spring 20, and the two ends of the second return spring 20 are respectively connected to the limit plate 17 and the baffle 18, and the inclined surface of the trapezoidal block 12 abuts against the surface of the cam 13.

[0026] The implementation principle of a toner feeding device with an anti-blocking structure in the embodiment of the present application is as follows: the scraper 7 processes the toner adhering to the feeding hopper 3 and the feeding pipe 5, the toner is put into the feeding hopper 3, the motor 9 is turned on, the gear 10 connected to the motor 9 starts to rotate, the gear 10 engages with the gear ring 4, thereby driving the gear ring 4 to rotate, and the scraper 7 on the inner wall of the gear ring 4 starts to rotate, scraping off the toner adhering to the feeding hopper 3 and the inner wall of the feeding pipe 5.

[0027] The knocking rod 11 shakes off the toner stuck on the discharge pipe 2. When the gear ring 4 rotates, the support column 6 at the bottom of the gear ring 4 pushes the dial plate 14. The dial plate 14 drives the connected cam 13 to perform a deflection motion with the support shaft 22 as the center. During the movement, it pushes the trapezoidal block 12. The trapezoidal block 12 drives the knocking rod 11 to move, causing the second return spring 20 to contract. When the support column 6 leaves the dial plate 14, the third return spring 19 connected between the fixed plate 16 and the dial plate 14 returns to its original position, and the trapezoidal block 12 also returns to its original position. The second return spring 20 rebounds, causing the knocking rod 11 to hit the discharge pipe 2.

[0028] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
