Technical Field

[0001] The utility model relates to the technical field of powder coating processing, in particular to a powder coating feeding device. 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 installed on the second floor. A feeding pipeline for feeding the extruder is installed on the building. After the mixer 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] Announcement No. CN212100861U proposes a powder coating feeding device, in which the user puts the raw materials into the mixing box through the feed pipe, turns on the power motor to drive the stirring blades to stir and mix the raw materials, turns on the drive push rod to drive the carrier plate to move up after the mixing is completed, turns on the electric push rod to drive the mixing box to move left to above the hopper of the extrusion equipment, opens the discharge pipe, and the mixed raw materials flow out of the discharge pipe. In this way, it is suitable for feeding when stirring the raw materials, and there is no need to waste manpower when feeding the extrusion equipment; however, the mixing box in the device needs to frequently move away from or close to the extruder to complete the manual feeding and unloading processes in succession, which is not convenient enough.

A sealing column is provided in the flow pipe, and the diameter of the sealing column is matched with the inner tube diameter of the flow pipe, and the inside of the sealing column is solid.

[0018] The above scheme can reduce the wind pressure when the bucket in the bucket elevator is in operation and at the same time facilitate the settling of dust inside the bucket elevator.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

The utility model is further described in combination with the drawings and embodiments:

[0027] Specifically, the mixing component includes a stirring roller 26, a stirring rod 27 and a driving motor 28. The stirring rollers 26 are symmetrically arranged inside the mixing equipment 2. A plurality of stirring rods 27 are arranged on the two stirring rollers 26 and one end of the stirring rollers 26 is respectively connected to a driving motor 28 fixed on the mixing equipment 2.

[0028] Further refinement of the embodiment of the present utility model is as follows: Figure 1 As shown, a vertically hanging cloth bag 25 is arranged between the second discharge port 31 and the second feed hopper 23; the cloth bag 25 is used to flexibly connect the mixing equipment 2 and the bucket 3 to reduce the impact of the vibration motor 24 on the bucket 3 when it is working, and effectively reduce the amount of dust overflow.

[0029] In order to further optimize the above-mentioned embodiment, rubber sealing rings which fit with the outer walls of the second discharge port 31 and the second feed hopper 23 are respectively provided at both ends of the cloth bag 25. The rubber sealing rings are not shown in the figure. The purpose is to make the two ends of the cloth bag 25 fit tightly with the outer walls of the second discharge port 31 and the second feed hopper 23 to enhance the sealing effect.

[0030] It should be noted that the extrusion device 1, the solenoid valve, the bucket elevator 3, the powder delivery pump 34 and the drive motor 28 are all electrically connected to the controller, which is not shown in the figure.

[0031] The workflow of this utility model:

[0032] First, the controller controls the operation of the powder delivery pump 34. While the powder delivery pump 34 is working, the second solenoid valves on several pipelines are opened and closed in sequence according to the process and time pre-set in the controller. Then, the raw materials and auxiliary materials of the powder coating are quantitatively extracted from their respective bins in sequence through the powder delivery pump 34 and successively transferred to the inside of the mixing equipment 2 through the bucket lift 3. This reduces the labor intensity of the existing manual feeding. When all the powder coating materials to be mixed in the mixing equipment 2 are injected, the controller immediately controls the powder delivery pump 34 to stop working, and then the drive motor 28 starts to work and cooperates with the stirring rod 27 to achieve a full and efficient stirring process of the materials. During the stirring process, the first solenoid valve 22 is always in a closed state. When the powder coating is mixed, the controller immediately controls the first solenoid valve 22 to open. At the same time, the high-frequency vibration of the vibration motor 24 can be used to realize the injection of the mixed powder coating into the extrusion equipment 1, and then the melting extrusion process of the powder coating can be realized.

[0033] Compared with the existing technology, the device can effectively reduce the dust overflow in the process of conveying, mixing and then introducing the powder coating into the extrusion equipment. At the same time, the use of cloth bags for connection can reduce the impact of the vibration motor on the bucket when it is working. In addition, when loading into the mixing equipment and unloading from the mixing equipment, the mixing equipment does not need to move and loading and unloading are completed automatically, and the powder coating loading effect is better.

[0034] In some embodiments, the bucket lift 3 includes several boxes, each of which is provided with a flow pipe, which is a circular tube, one end of which is sealed and connected to the inner wall of the box, and the other end of the flow pipe extends through the box to the outside, and several groups of air holes are arranged on the flow pipe at equal intervals. The flow pipe is equipped with a sealing column, the diameter of the sealing column is adapted to the inner tube diameter of the flow pipe, and the inside of the sealing column is solid; the above-mentioned embodiment scheme has been fully disclosed in the announcement No. CN217024007U, a dust prevention device for a bucket lift for compound fertilizer production, and its principle is not described in detail and is not specifically shown. Its purpose is to reduce the wind pressure during the operation of the bucket in the bucket lift 3 and facilitate the sedimentation of the dust inside the bucket lift 3 to the bottom of the box. This design is also applicable to the conveying and loading process of the powder coating in this application.

[0035] In other embodiments, a crushing blade is provided on the stirring rod 27, which is not shown in the figure; the crushing blade can effectively break up the agglomerated powder coating during the mixing and stirring process of the powder coating, thereby ensuring that the particle size of the powder coating subsequently introduced into the extrusion equipment 1 meets the requirements, so that the subsequent melt extrusion effect is better.
