Description

Technical Field

[0001] The utility model relates to the technical field of zinc oxide processing, in particular to a zinc oxide processing feeding device. Background Art

[0002] Zinc oxide is an oxide of zinc that is insoluble in water but soluble in acids and strong bases. Zinc oxide is a commonly used chemical additive and is widely used in the production of plastics, silicate products, synthetic rubber, lubricants, paints and coatings, ointments, adhesives, foods, batteries, flame retardants and other products. Zinc oxide has a large energy band gap and exciton binding energy, high transparency, and excellent room-temperature luminescence properties. It is used in liquid crystal displays, thin-film transistors, light-emitting diodes and other products in the semiconductor field. In addition, microparticle zinc oxide as a nanomaterial has also begun to play a role in related fields. During the production of zinc oxide, a feeding device is used to feed the zinc oxide processing raw materials into the zinc oxide processing equipment.

[0003] For example, the application number is 202322469188.1, which is a feeding device for processing zinc oxide with anti-caking. By setting a dispersing mechanism in the feeding device for processing zinc oxide with anti-caking, the contact between the pressing block and the fine filter screen is achieved by utilizing the structural design in the dispersing mechanism, thereby achieving the purpose of improving the anti-caking effect of the device, effectively preventing the clogging of the filter holes in the filter screen, ensuring the feeding efficiency of the device, and facilitating the subsequent operation;

[0004] If the zinc oxide processing raw material fed into the feed port adheres to the inner wall surface of the feed port, the inner diameter of the feed port will gradually decrease over time, resulting in a problem of reduced efficiency in the material feeding speed through the feed port to the device body.

[0005] Therefore, those skilled in the art provide a zinc oxide processing feeding device to solve the problems raised in the above background technology. Utility Model Content

DETAILED DESCRIPTION

[0022] See also Figures 1 to 3 In an embodiment of the utility model, a zinc oxide processing feeding device includes a feeding box 1, a feeding pipe 2 is fixedly arranged on the feeding box 1, a feeding mechanism is arranged in the feeding pipe 2, the feeding mechanism is used to transport the zinc oxide powder put in the feeding pipe 2 to the feeding box 1, a filtering device is arranged on the feeding pipe 2, the filtering device is used to filter the zinc oxide powder put in the feeding pipe 2, a linkage component is arranged between the filtering device and the feeding mechanism, and the feeding mechanism will drive the filtering device to shake up and down through the linkage component while transporting the zinc oxide powder in the feeding pipe 2.

[0023] The feeding mechanism includes a first transmission shaft 3 rotatably connected to the feed pipe 2, a first spiral blade 4 is fixedly provided on the outer wall of the first transmission shaft 3, a servo motor 5 is docked at one end of the first transmission shaft 3, the servo motor 5 is fixedly provided at one end of the feed pipe 2, a first bevel gear 6 is fixedly provided at the other end of the first transmission shaft 3, and a protrusion 7 is fixedly provided on the outer wall of the first transmission shaft 3. The filtering device includes a feed hopper 8 fixedly provided on the feed pipe 2, the feed hopper 8 is located above the protrusion 7, two limit frames 10 are fixedly provided in the feed hopper 8 in sequence, a filter plate 11 is provided between the two limit frames 10, a spring 12 is fixedly provided on the filter plate 11, and the end of the spring 12 away from the filter plate 11 is connected to one of the limit frames 10. The linkage assembly includes a linkage support rod 13 fixedly arranged on the filter plate 11. A connecting slot is opened at one end of the linkage support rod 13 away from the filter plate 11. A rotating wheel 14 is rotatably arranged in the connecting slot. The rotating wheel 14 and the protrusion 7 are in the same plane, and the rotating wheel 14 is attached to the outer wall surface of the first transmission shaft 3.

[0024] In this embodiment, the servo motor 5 is first started. The start of the servo motor 5 drives the first transmission shaft 3 connected thereto to rotate. The rotation of the first transmission shaft 3 drives the first spiral blade 4 on its outer wall to rotate. While the first transmission shaft 3 is rotating, the rotating wheel 14 attached to the outer wall of the first transmission shaft 3 rolls. When the rotating wheel 14 rolls the protrusion 7 on the outer wall of the first transmission shaft 3, the linkage strut 13 pushes the filter plate 11 to move upward. When the rotating wheel 14 presses over the protrusion 7 on the outer wall of the first transmission shaft 3, the rotating wheel 14 is still attached to the outer wall of the first transmission shaft 3, and reciprocates in sequence. The filter plate 11 will shake up and down. At this time, the zinc oxide powder to be unloaded is put into the feed hopper 8, and the zinc oxide powder in the feed hopper 8 will fall on the filter plate 11. The zinc oxide powder on the filter plate 11 screens the zinc oxide powder particles mixed in the zinc oxide powder and the zinc oxide powder through the filter holes.

[0025] By setting up the feeding mechanism, the zinc oxide powder put into the feeding pipe 2 can be fully output to the discharge box 1, so as to avoid the zinc oxide powder put into the feeding pipe 2 from adhering to the inner wall of the feeding pipe 2. The accumulation of zinc oxide powder on the inner wall of the feeding pipe 2 will cause the inner diameter of the feeding pipe 2 to be reduced, thereby resulting in the problem of reduced efficiency of the discharge speed from the feeding pipe 2 to the discharge box 1. By setting up the filtering device, the zinc oxide powder put into the feeding pipe 2 can be screened from zinc oxide powder particles and zinc oxide powder, so as to reduce the influence of zinc oxide powder particles on zinc oxide processing. In addition, the filtering device can shake the zinc oxide powder particles, so as not only to improve the screening efficiency of zinc oxide powder, but also to shake some zinc oxide powder particles into powder, so as to reduce the work flow of processing zinc oxide powder particles into zinc oxide powder, thereby reducing the production cost of zinc oxide processing. The setting of the linkage component enables the feeding mechanism to drive the filtering device to run together with the running of the filtering device.

[0026] like Figure 4 As shown, a feeding tube 15 is fixedly provided on the lower end surface of the feeding box 1, a second transmission shaft 16 is provided in the feeding tube 15, a second bevel gear 17 is fixedly provided at one end of the second transmission shaft 16, the second bevel gear 17 is meshed with the first bevel gear 6, and the other end of the second transmission shaft 16 is rotatably connected with the limiting assembly. The limiting assembly includes a first limiting member 18 and a second limiting member 19 fixedly provided in the feeding tube 15, the first limiting member 18 is located above the second limiting member 19, and one end of the second transmission shaft 16 passes through the first limiting member 18 and is rotatably connected with the second limiting member 19. A second spiral blade 20 is fixedly provided on the second transmission shaft 16, and the second spiral blade 20 is located between the first limiting member 18 and the second limiting member 19, and a connecting plate 21 is fixedly provided at one end of the feeding tube 15 away from the feeding box 1.

[0027] In this embodiment, the first transmission shaft 3 drives the first bevel gear 6 at one end thereof to rotate while rotating, the rotation of the first bevel gear 6 drives the second bevel gear 17 to rotate, the rotation of the second bevel gear 17 drives the second transmission shaft 16 to rotate, the rotation of the second transmission shaft 16 drives the second spiral blade 20 on its outer wall to rotate, and the rotation of the second spiral blade 20 discharges the zinc oxide powder that falls into the discharge pipe 15.

[0028] The second bevel gear 17 can be used to transfer the kinetic energy generated by the rotation of the first transmission shaft 3 to the second transmission shaft 16. The rotation of the second transmission shaft 16 can not only discharge the zinc oxide powder at the discharge port of the discharge pipe 15 at a uniform speed, but also prevent the accumulation of zinc oxide powder at the discharge port of the discharge pipe 15 and cause blockage of the discharge port of the discharge pipe 15.

[0029] The working principle of the utility model is:

[0030] First, start the servo motor 5. The start of the servo motor 5 drives the first transmission shaft 3 connected thereto to rotate. The rotation of the first transmission shaft 3 drives the first spiral blade 4 on its outer wall to rotate. While the first transmission shaft 3 is rotating, the rotating wheel 14 attached to the outer wall of the first transmission shaft 3 rolls. When the rotating wheel 14 rolls the convex block 7 on the outer wall of the first transmission shaft 3, the linkage support rod 13 pushes the filter plate 11 to move upward. When the rotating wheel 14 presses over the convex block 7 on the outer wall of the first transmission shaft 3, the rotating wheel 14 is still attached to the outer wall of the first transmission shaft 3, and reciprocates in sequence. The filter plate 11 will shake up and down. At this time, the zinc oxide powder to be unloaded is put into the feed hopper 8, and the zinc oxide powder in the feed hopper 8 will fall. On the filter plate 11, the zinc oxide powder on the filter plate 11 passes through the filter holes to screen the zinc oxide powder particles mixed in the zinc oxide powder and the zinc oxide powder, and the screened zinc oxide powder will fall into the feed pipe 2, and the zinc oxide powder in the feed pipe 2 will be transported to the discharge pipe 15 under the rotation of the first spiral blade 4. The first transmission shaft 3 will drive the first bevel gear 6 at one end thereof to rotate while rotating, and the rotation of the first bevel gear 6 will drive the second bevel gear 17 to rotate, and the rotation of the second bevel gear 17 will drive the second transmission shaft 16 to rotate, and the rotation of the second transmission shaft 16 will drive the second spiral blade 20 on its outer wall to rotate, and the rotation of the second spiral blade 20 will discharge the zinc oxide powder that falls into the discharge pipe 15.
