Description

Technical Field

[0001] The utility model relates to the field of powder coating feeding equipment, in particular to a powder coating production device which is convenient for feeding. Background Art

[0002] In the production of powder coatings, mixing, extrusion, cooling, rough cutting and grinding are generally required. In order to facilitate the feeding of materials in the extrusion process, the factory building is generally set up in two floors, with the extruder installed on the first floor and the mixer body installed on the second floor. A feeding pipeline for feeding the extruder is installed on the building. When the mixer body finishes mixing, the mixed powder will be poured into the powder coating feeding device, and then fed to the extruder through the feeding pipeline.

[0003] The current powder coating feeding device is not stable during the feeding process, which can easily affect the processing process. At the same time, a large amount of dust will be generated during the feeding process, which seriously affects the working environment of the staff.

When feeding is required, the powder coatings can be evenly dropped from the storage box into the feeding pipe of the extruder, so that the feeding is smooth and a large amount of dust will not be generated during the feeding process. However, the device requires manual intervention in multiple links to complete the feeding. The operation steps are time-consuming, labor-intensive and inconvenient, and the degree of automation needs to be improved. Utility Model Content

[0008] This device automatically realizes the feeding process to the extrusion equipment after the powder coating is mixed, without manual intervention. The powder delivery pump is used in conjunction with the star-shaped discharger to smoothly complete the feeding of the powder coating, and the operation is convenient. At the same time, the fine crushing component is combined with the filter screen to ensure that the particle size of the powder coating meets the requirements, thereby avoiding damage caused by the powder delivery pump in the process of conveying large-particle or agglomerated powder coatings, and extending the service life of the device.

[0010] In the above scheme, when the powder accumulation height in the crushing box reaches the upper limit detection height value preset in the ultrasonic sensor, the ultrasonic sensor immediately feeds back a signal to the controller, and then the controller controls the solenoid valve to close and prohibit further feeding into the crushing box.

[0011] Furthermore, the fine grinding component includes a rotating shaft and fine powder blades. The rotating shaft is rotatably connected in the grinding box, one end of the rotating shaft is connected to a driving box and a plurality of fine powder blades are arranged on the rotating shaft.

[0013] Furthermore, the fine powder blade is designed in an S shape.

[0014] In the above scheme, the fine powder blade adopts an S-shaped design to further expand the contact area between the powder coating and the fine powder blade to achieve a better fine powder effect.

[0015] Furthermore, wear-resistant elbows are provided at the bending parts of the input pipe and the output pipe.

[0016] The above solution can effectively reduce the wear caused by the powder coating impacting the bending part of the input pipe or the output pipe during the transportation process through the wear-resistant elbow, and further extend the service life of the device.

At the same time, the fine crushing component and the filter screen can ensure that the particle size of the powder coating meets the requirements, thereby avoiding damage caused by the powder delivery pump in the process of conveying large-particle or agglomerated powder coatings, extending the service life of the device. In addition, sealed transmission can be achieved throughout the process, and dust overflow will not occur, and the feeding effect is significantly improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] like Figure 1 and Figure 2As shown, a powder coating production device that is easy to load includes an extrusion device 1 and a mixer body 4, the extrusion device 1 includes a feed hopper 11, the feed hopper 11 is connected to a star-shaped discharger 12, a sealing plate 13 is arranged on the star-shaped discharger 12, a powder delivery pump 2 is arranged on the extrusion device 1, the input end of the powder delivery pump 2 is connected to an input pipe 22, one end of the input pipe 22 is connected to the bottom of a crushing box 3, the top of the crushing box 3 is connected to the discharge port of the mixer body 4, and an electromagnetic valve is arranged on the discharge port of the mixer body 4, the electromagnetic valve is shown as unnumbered in the figure, and a fine crushing component for extending the service life of the powder delivery pump 2, a filter screen 33 for screening small-particle powder coatings, and a symmetrically distributed anti-stacking platform 31 are arranged in the crushing box 3 from top to bottom, a vibration motor 32 is arranged on the crushing box 3 and the mixer body 4, and an output end of the powder delivery pump 2 is connected to an output pipe 21, and the output pipe 21 passes through the sealing plate 13 and is connected to the star-shaped discharger 12.

[0025] Specifically, the fine grinding component includes a rotating shaft 34 and a fine powder blade 35.

[0027] Further refinement of the embodiment of the present utility model is as follows: Figure 1 As shown, an ultrasonic sensor electrically connected to the electromagnetic valve is arranged in the crushing box 3 to detect the accumulation height of the powder coating in the crushing box 3 in real time.

[0028] It should be noted that the star-shaped discharger 12 , the powder delivery pump 2 , the solenoid valve, the vibration motor 32 , the ultrasonic sensor 36 and the driving assembly are all electrically connected to the controller, which is not shown in the figure.

[0029] The workflow of this utility model:

[0030] First, the controller controls the solenoid valve on the discharge port of the mixer body 4 and the vibration motor 32 arranged thereon to open, and then the powder coating is injected into the crushing box 3. When the powder accumulation height in the crushing box reaches the upper limit detection height value preset in the ultrasonic sensor, the ultrasonic sensor immediately feeds back a signal to the controller, and then the controller controls the solenoid valve to close and prohibit further feeding into the crushing box 3. Then the vibration motor 32 on the crushing box 3 starts to work, and at the same time, the fine powder blade 35 rotates at a high speed under the action of the driving component. At this time, the powder coating with small particle size can directly flow through the filter screen 33 and enter the input pipe 22, and the powder with large particle size and agglomeration The powder coating stays on the filter screen 33 and keeps jumping. During the jumping process, it contacts with the fine powder blade 35 to achieve fine and thorough crushing and dispersion. Finally, the powder coating in the crushing box 3 can flow into the input pipe 22 through the filter screen 33. As the fine powder screening is carried out, the controller controls the powder delivery pump 2 to work and then suck the powder coating in the input pipe 22 and inject it into the star-shaped discharger 12. Then, the powder coating can be stably and evenly fed into the extrusion device 1 through the star-shaped discharger 12. When the batch of powder coating is fully fed, the controller controls the solenoid valve to open again, and then the above process is circulated to start a new round of feeding process.

At the same time, the fine crushing component is combined with the filter screen 33 to ensure that the particle size of the powder coating meets the requirements, thereby avoiding damage to the powder delivery pump 2 during the transportation of large-particle or agglomerated powder coatings, extending the service life of the device. In addition, sealed transmission can be achieved in the entire process, and dust overflow will not occur, and the feeding effect is significantly improved.
