Description

Technical Field

[0001] This utility model relates to the field of powder conveying technology, and in particular to a coating powder conveying device. Background Technology

[0002] A powder coating conveying device is a specialized device for conveying and feeding powder coatings during the coating production process. Its main function is to transport powder coatings from storage containers to production equipment, ensuring the continuity and stability of the production process. Powder coating conveying devices are widely used in many industries such as chemical, food, and building materials. In particular, in coating production, they can significantly improve production efficiency and product quality.

[0003] The current coating powder conveying device has revealed several performance shortcomings that urgently need to be addressed in actual operation. The bag breaking process is inefficient, the manual operation is cumbersome, and it is difficult to meet the continuous supply requirements of large-scale production. The device lacks cross-layer conveying adaptability, and the structural design is only suitable for planar transmission. When facing multi-story factory layouts, it is necessary to rely on forklifts for transportation or manual handling, which is not only inefficient but also poses risks such as material spillage and packaging damage. Therefore, we need to upgrade and transform the existing technology to overcome the existing problems and deficiencies. Utility Model Content

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figure 1 As shown in Figure 4, the coating powder conveying device provided in this embodiment includes a hopper 1, an upper cover 2, a conveying component 3, and a dust removal component 4. The hopper 1 is provided with a placement rack 11 inside. The upper cover 2 is fixed to the upper end of the hopper 1. The conveying component 3 is located at the rear end of the hopper 1 and is connected to the lower end of the hopper 1. The dust removal component 4 is connected to the top of the upper cover 2.

[0024] In this embodiment, the conveying assembly 3 includes a connecting pipe 31 that extends to the bottom of the hopper 1. A conveying pipe 32 is fixed behind the connecting pipe 31. A conveying pump 33 is connected to the top of the conveying pipe 32. One end of the conveying pump 33 has a discharge port 35, and the other end of the conveying pump 33 is connected to a pressurizing fan 34. A pressure gauge 36 is connected to the outside of the conveying pump 33 and the pressurizing fan 34. The front end of the placement frame 11 has an installation groove 14. A bag-breaking knife 13 is provided on the installation groove 14. The bag-breaking knife 13 and the installation groove 14 have corresponding installation holes 15, and installation bolts 16 are screwed into the installation holes 15. The front end of the placement frame 11 is provided with... A metal platform 12 is provided, which is level with the placement frame 11 and fixed at the front end of the feeding hopper 1. Powder bags are placed on the metal platform 12, and the bags are pushed in and opened by the bag-breaking knife 13. The powder material enters the conveying pipe 32 from the feeding hopper 1, and is pumped to the discharge port 35 by the conveying pump 33 and the pressurizing fan 34. This enables rapid bag breaking and cross-layer conveying of powder bags. The structure is simple and easy to operate, and it is convenient to adapt to powder material conveying operations of different layer heights. There is no need to break the bags in advance. Feeding and bag breaking can be completed at the same time, which improves the conveying efficiency of the equipment.

[0025] In this embodiment, the dust removal component 4 includes a negative pressure fan 41 fixed to the top of the upper cover 2. A dust removal pipe 42 is connected to the upper end of the negative pressure fan 41, and a bag filter 44 is connected to the top of the dust removal pipe 42. A pressure pump 43 is provided on one side of the dust removal pipe 42. A fixing plate 45 is provided at the upper end of the negative pressure fan 41. Multiple sets of fixing holes 46 are opened on the fixing plate 45. Fixing bolts 47 are screwed between the fixing holes 46 and the upper cover 2. The dust generated by the feeding is drawn into the dust removal pipe 42 by the negative pressure fan 41 and then transported into the bag filter 44 through the dust removal pipe 42. This can effectively collect and treat the dust generated by the feeding, reduce the dust concentration in the air, reduce the waste of material resources, reduce the problem of inhalation lung disease, and improve the safety of the equipment.

[0026] The working principle and process of this utility model are as follows: First, the powder bag is placed on the metal platform 12, and the bag is pushed inward and placed on the placement rack 11. During the movement of the bag, it comes into contact with the bag-breaking knife 13 and cuts open the bottom of the bag. The worker lifts the bag upward so that the powder material falls into the feed hopper 1. The powder is then pumped to the discharge port 35 by the conveying pump 33 and the pressurizing fan 34. This achieves the cross-layer conveying operation of the powder bag. During the conveying process, the negative pressure fan 41 and the pressurizing pump 43 are turned on simultaneously. The negative pressure fan 41 draws the dust generated by the feeding into the dust removal pipe 42. The dust is then conveyed to the bag filter 44 through the dust removal pipe 42, which can reduce the dust concentration in the air, reduce the waste of material resources, and reduce the problem of inhalation lung disease.
