Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, and in particular to a feeding device for a plastic grinding mill. Background Technology

[0002] Pneumatic grinding mills are highly efficient grinding devices widely used in the grinding of mineral materials in metallurgy, building materials, chemical industry, mining, and other fields. The fineness of the material being ground and the fineness of the output material are determined based on these factors.

[0003] In the prior art, such as the intermittent feeding device for a vertical grinding mill for powder coatings disclosed in Chinese Patent Publication No. CN220346111U, a base plate is included. The upper surface of the base plate is fixedly mounted with the main body of the vertical grinding mill and a storage hopper. A feeding assembly connects the main body of the vertical grinding mill and the storage hopper, feeding the material inside the storage hopper into the main body of the vertical grinding mill. The feeding assembly is equipped with a motor, and a drive assembly connects the motor and the feeding assembly, enabling intermittent operation of the feeding assembly. In this invention, during use, when intermittent feeding is required, the user only needs to remove some of the locking pins with a wrench to achieve intermittent feeding. This avoids the motor burning out due to excessive starting current when starting frequently, and also ensures that a sufficient amount of raw material can be filled at once when the feeding assembly is running, effectively eliminating the limitations of existing devices.

[0004] However, the existing feeding devices for plastic pulverizers require manual feeding, and impurities inside the powder can enter the pulverizer through the feeding device, resulting in uneven powder grinding. Therefore, a new feeding device for plastic pulverizers is needed to solve this problem. Utility Model Content

[0005] The purpose of this invention is to provide a feeding device for a plastic pulverizer, which has a good pulverizing effect.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a feeding device for a plastic grinding mill, comprising a support plate, a feeding box fixedly connected to the top of the support plate, a feed pipe fixedly connected to the outside of the feeding box, a first motor fixedly connected to the outside of the feed pipe, a drive shaft fixedly connected to the output end of the first motor, a spiral blade fixedly connected to the outside of the drive shaft, a connecting block fixedly connected to the inner wall of the support plate, a second motor fixedly installed on the top of the connecting block, a threaded shaft fixedly connected to the output end of the second motor, a lifting plate threadedly connected to the outside of the threaded shaft, a storage box fixedly connected to the bottom of the lifting plate, an isolation mesh plate fixedly connected to the bottom of the storage box, an isolation mesh fixedly connected inside the isolation mesh plate, grooves are provided on both sides inside the storage box, a vibrator is fixedly installed inside the grooves, and a gate is provided inside the feeding box.

[0007] By adopting the above technical solution, the powder is conveyed through the feed pipe. The first motor is started, driving the drive shaft and spiral blades to rotate. The spiral blades, being spiral-shaped, convey the powder, allowing it to enter the feeding hopper, achieving automatic feeding. The powder inside the feed pipe is then conveyed to the storage hopper. The vibrator is then started, driving the storage hopper to generate vibration force. This vibration force causes the powder to shake inside the storage hopper, after which the powder falls through the isolation mesh inside the isolation plate to the feeding hopper. At the bottom of the box, impurities are isolated inside the isolation mesh. When processing the impurities inside the isolation mesh, the second motor is started, which drives the threaded shaft to rotate. The lifting plate is threadedly connected to the outside of the threaded shaft, thereby causing the lifting plate to lift the storage box and the isolation mesh, raising the isolation mesh to the top of the feeding box, making it easier to remove the impurities inside the isolation mesh, thus achieving the effect of easy impurity cleaning. This device improves the convenience of powder feeding and the grinding effect of powder by automatically conveying powder and screening impurities.

[0008] A further feature of this invention is that the storage box is internally threaded with bolts, and the bolts extend into the interior of the isolation mesh plate.

[0009] By adopting the above technical solution, the bolts are threaded to the inside of the isolation mesh plate, and then the bolts are extended into the inside of the storage box, thereby fixing the isolation mesh plate inside the storage box. It is also extremely convenient to disassemble the isolation mesh plate.

[0010] A further feature of this invention is that the number of bolts is six, and the six bolts are distributed in a circular array.

[0011] By adopting the above technical solution and using six bolts, the fixing effect of the isolation mesh plate is improved.

[0012] A further feature of this invention is that a lifting ring is sleeved on the outside of the feed pipe, and a screw pin is threaded inside the lifting ring.

[0013] By adopting the above technical solution, the lifting ring is attached to the outside of the feed pipe, and then the screw is threaded to the inside of the lifting ring, so that the screw extends into the ceiling, thereby supporting the feed pipe through the lifting ring.

[0014] A further feature of this invention is that a hinge is fixedly installed at the edge of the top of the feeding box, and a cover plate is hinged to the feeding box via the hinge.

[0015] By adopting the above technical solution, the cover plate is hinged to the opening of the feeding box. During the feeding process, the cover plate closes the opening of the feeding box, covering the opening of the feeding box and preventing the powder from scattering.

[0016] A further feature of this invention is that a locking block is fixedly connected to the inner side of the cover plate, and absorbent cotton is locked inside the locking block.

[0017] By adopting the above technical solution, the clamp is set on the inside of the cover plate, and the absorbent cotton is clamped to the inside of the cover plate through the clamp. When the powder is scattered inside the feeding box, the absorbent cotton absorbs the scattered powder. Then the absorbent cotton is disassembled inside the clamp, and the powder can be discharged by tapping the absorbent cotton.

[0018] A further feature of this invention is that a handle is fixedly connected to the outer side of the cover plate, and a protective sleeve is fixedly connected to the outer side of the handle.

[0019] By adopting the above technical solution, closing the cover by holding the handle is relatively convenient.

[0020] A further feature of this invention is that support rods are fixedly connected to both sides of the top of the support plate, and the support rods are fixedly connected to the outside of the feeding box.

[0021] By adopting the above technical solution, the two ends of the support rod are fixed to the outside of the support plate and the feeding box, respectively, thereby improving the stability of the feeding box.

[0022] A further feature of this invention is that the bottom of the support plate is fixedly connected with four columns.

[0023] By adopting the above technical solution, four columns are distributed at the four corners of the bottom of the support plate, and the support plate is supported by the columns.

[0024] A further feature of this invention is that the top of the feed pipe has a feed inlet.

[0025] By adopting the above technical solution, the powder enters the inside of the feed pipe through the feed inlet.

[0026] The beneficial effects of this utility model are:

The first motor is started, driving the drive shaft and spiral blades to rotate. The spiral blades, being spiral-shaped, convey the powder, allowing it to enter the feeding box for automatic feeding. The powder inside the feed pipe is then conveyed to the storage box. The vibrator is then started, causing it to drive the storage box and generate a vibration force, which causes the powder to move... The material is shaken inside the storage bin, and then the powder falls to the bottom of the feeding bin through the isolation mesh inside the isolation plate. Impurities are isolated inside the isolation mesh. When processing the impurities inside the isolation mesh, the second motor is started, which drives the threaded shaft to rotate. The lifting plate is threadedly connected to the outside of the threaded shaft, which in turn lifts the storage bin and the isolation mesh, raising the isolation mesh to the top of the feeding bin. This makes it easier to remove the impurities inside the isolation mesh, achieving the effect of easy impurity cleaning. This device improves the convenience of powder feeding and the grinding effect of powder by automatically conveying powder and screening impurities.

During the powder feeding process, the cover plate closes the opening of the feeding box, covering the opening of the feeding box and preventing the powder from scattering. The locking block is located on the inside of the cover plate, and the absorbent cotton is locked to the inside of the cover plate through the locking block. When the powder scatters inside the feeding box, the absorbent cotton absorbs the scattered powder. Afterwards, the absorbent cotton is disassembled inside the locking block, and the powder can be discharged by tapping the absorbent cotton. Attached Figure Description

Impurities are isolated inside the isolation net 13. In the process of processing impurities inside the isolation net 13, the second motor 8 is started, causing the second motor 8 to drive the threaded shaft 9 to rotate. The lifting plate 10 is threadedly connected to the outside of the threaded shaft 9, thereby causing the lifting plate 10 to lift the storage box 11 and the isolation net 13, raising the isolation net 13 to the top of the feeding box 2, thus facilitating the removal of impurities inside the isolation net 13 and achieving the effect of easy impurity cleaning. This device improves the convenience of powder feeding and the grinding effect of powder by automatically conveying powder and screening impurities. The storage box 11 is internally threaded with bolts 15, which extend into the interior of the isolation net plate 12. The bolts 15 are threadedly connected to the interior of the isolation net plate 12, and then extended into the interior of the isolation net plate 12.

The powder inside the feed pipe 3 is then conveyed to the storage box 11. The vibrator 14 is started, driving the storage box 11 to generate a vibration force. This vibration force causes the powder to vibrate inside the storage box 11. The powder then falls through the isolation mesh 13 inside the isolation mesh plate 12 to the bottom of the feeding box 2. Impurities are isolated inside the isolation mesh 13. While processing the impurities inside the isolation mesh 13, the second motor 8 is started, driving the threaded shaft 9 to rotate. The lifting plate 10 is threadedly connected to the outside of the threaded shaft 9, thus causing the lifting plate... 10 drives the storage box 11 and the isolation net 13 to be lifted, raising the isolation net 13 to the top of the feeding box 2, thereby facilitating the removal of impurities inside the isolation net 13 and achieving the effect of easy cleaning of impurities. This device improves the convenience of powder feeding and the grinding effect of powder by automatically conveying powder and screening impurities. The cover plate 18 is hinged to the opening of the feeding box 2.
