Description

Technical Field

[0001] This utility model relates to the field of powder coating production technology, specifically to a crusher grinding roller for powder coating production. Background Technology

[0002] Powder coatings are solid powdered synthetic resin coatings composed of solid resin, pigments, fillers, and additives. Unlike ordinary solvent-based and water-based coatings, their dispersion medium is air, not solvent or water, resulting in solvent-free pollution. Powder coatings are broadly classified into thermoplastic and thermosetting types. Thermoplastic powder coatings have a poorer film appearance and weaker adhesion to metals, so they are rarely used in automotive painting. Automotive painting generally uses thermosetting powder coatings. Thermosetting powder coatings use thermosetting synthetic resins as film-forming substances. During the drying process, the resin melts first and then cures into a smooth and hard film through chemical cross-linking. The appearance, various mechanical properties, and corrosion resistance of the film formed by this type of coating can meet the requirements of automotive finishing.

[0003] For example, patent document CN 221471932 U discloses a powder coating grinding device, including a primary grinding box and a secondary grinding box connected to the bottom of the primary grinding box; the top of the primary grinding box is connected to a box cover, and a feed pipe is installed on the box cover; the primary grinding box has a grinding chamber, and a grinding roller is installed in the grinding chamber; a guide cone is fixedly connected to the top of the grinding roller; the top of the box cover has a first driving component for driving the grinding roller to rotate; the secondary grinding box has a processing chamber, and the grinding chamber is connected to the processing chamber through a connecting chamber; an arc-shaped mesh is installed at the bottom of the processing chamber; in this utility model, the top of the grinding roller is connected to the guide cone, which reduces the accumulation of the input powder coating on the top of the grinding roller, and facilitates continuous conveying to the grinding roller and the grinding chamber for grinding operation; the grinding roller in the primary grinding box cooperates with the grinding disc in the secondary grinding box to effectively grind the powder coating and improve the grinding effect of the powder coating.

[0004] However, in actual operation, due to its structural limitations, this structure can only be used for simple vertical grinding in powder coating production crushers. The grinding rollers cannot make sufficient contact with the powder coating, resulting in poor grinding effect. Multiple grinding operations are often required to meet production needs. Furthermore, the equipment cannot perform disassembly, cleaning, and maintenance of the grinding rollers, which cannot meet daily usage requirements. Therefore, it is urgent to design a grinding roller for powder coating production crushers to solve the above problems. Utility Model Content

It is often necessary to perform multiple grinding operations to meet production requirements. At the same time, the equipment cannot perform disassembly, cleaning and maintenance operations on the inside of the grinding roller, which cannot meet the daily use needs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a grinding roller for a crusher used in powder coating production, comprising a conical upper seat and a conical lower seat, wherein the conical upper seat and the conical lower seat have the same structure but opposite directions, and grinding components are provided inside the conical upper seat and the conical lower seat, and a cover assembly is sleeved between the conical upper seat and the conical lower seat;

[0007] The grinding assembly includes a main crushing roller, and the main crushing roller is disposed inside the upper conical seat and the lower conical seat. Both the upper and lower ends of the main crushing roller are fixedly connected to a secondary conical roller.

[0008] The cover assembly includes an arc-shaped cover, which is fitted onto the outer surface between the conical upper seat and the conical lower seat, and a movable shaft is provided at one end of the arc-shaped cover.

[0009] Preferably, a fastening bolt seat is fixedly connected to the other end of the arc-shaped cover, and a sealing strip is provided between the two ends of the movable shaft.

[0012] Preferably, a sealing ring is provided between the upper conical seat and the lower conical seat.

[0013] Preferably, a feed seat is fixedly connected to the top of the conical upper seat, and a discharge seat is fixedly connected to the bottom of the crushing main roller.

[0014] Preferably, a drive motor is fixedly connected to the bottom end of the discharge seat.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This powder coating production crusher grinding roller, through its conical upper seat, conical lower seat, main crushing roller, conical auxiliary roller, material leveling head, material leveling ring grid, feed seat, discharge seat, and drive motor, enables the equipment to perform more efficient crushing and grinding operations in powder coating production. In actual use, the operator first pours the powder coating to be ground into the feed seat at the top of the conical upper seat. Then, the powder coating flows down along the conical upper and lower seats and is quickly discharged from the discharge seat. Simultaneously, the conical auxiliary roller on the inner wall of the conical upper seat... The roller can be fitted with a conical auxiliary roller for limiting. When the drive motor is started, the main crushing roller and the upper and lower conical auxiliary rollers can rotate. At this time, the powder coating inside the conical auxiliary roller can be initially ground, and then a conical diffusion grinding operation is carried out along the conical upper seat.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 One embodiment provided by this utility model:

[0026] A grinding roller for a crusher used in powder coating production includes a conical upper seat 1 and a conical lower seat 2. The conical upper seat 1 and the conical lower seat 2 have the same structure but opposite directions. Grinding components are installed inside the conical upper seat 1 and the conical lower seat 2. A cover assembly is sleeved between the conical upper seat 1 and the conical lower seat 2. A sealing ring 13 is installed between the conical upper seat 1 and the conical lower seat 2. A feed seat 14 is fixedly connected to the top of the conical upper seat 1. A discharge seat 15 is fixedly connected to the bottom of the crushing main roller 3. A drive motor 16 is fixedly connected to the bottom of the discharge seat 15. When the drive motor 16 is started, the crushing main roller 3 and the upper and lower conical auxiliary rollers 4 can rotate. At this time, the powder coating inside the conical auxiliary rollers 4 can be initially ground, and then a conical diffusion grinding operation is performed along the conical upper seat 1. After that, vertical grinding is performed through the crushing main roller 3 and the arc-shaped cover 5. Finally, a converging final grinding operation can be performed at the crushing main roller 3.

[0027] The grinding assembly includes a main crushing roller 3, a conical upper seat 1, and a conical lower seat 2, both of which house the main crushing roller 3. Conical auxiliary rollers 4 are fixedly connected to both the upper and lower ends of the main crushing roller 3. The covering assembly includes an arc-shaped cover 5, which is fitted onto the outer surface between the conical upper seat 1 and the conical lower seat 2. A movable shaft 6 is located at one end of the arc-shaped cover 5, and a fastening bolt seat 7 is fixedly connected to the other end. A sealing strip 8 is provided between the two ends of the movable shaft 6, and a grinding groove 9 is formed inside the movable shaft 6. The grinding tank 9 has a grinding liner 10 at its center, the conical auxiliary roller 4 has a material leveling head 11 at its top, and the conical upper seat 1 has a material leveling ring grid 12 on its inner wall. The arc-shaped cover 5 is unfolded through the movable shaft 6 and then covered onto the crushing main roller 3 between the conical upper seat 1 and the conical lower seat 2. The sealing operation at the connection can be performed by the sealing rubber ring 13 between the conical upper seat 1 and the conical lower seat 2. Finally, the locking and fixing operation can be performed by fastening the bolt seat 7.

[0028] Working principle: During use, the operator first pours the powder coating to be ground into the feed seat 14 at the top of the conical upper seat 1. Then, the powder coating flows down the conical upper seat 1 and the conical lower seat 2 and is quickly discharged from the discharge seat 15. At the same time, the conical auxiliary roller 4 on the inner wall of the conical upper seat 1 can be fitted and limited by a cover. Normally, when the drive motor 16 is started, the crushing main roller 3 and the upper and lower conical auxiliary rollers 4 can rotate. At this time, the powder coating inside the conical auxiliary roller 4 can be initially ground, and then undergoes conical diffusion grinding along the conical upper seat 1. After that, it undergoes vertical grinding through the crushing main roller 3 and the arc-shaped cover 5, and finally, it can be concentrated and ground at the crushing main roller 3. The operation ensures that the powder coating is effectively ground from multiple angles, improving the overall grinding effect of the equipment. During daily use, the operator can unfold the arc-shaped cover 5 through the movable shaft 6, and then cover the crushing main roller 3 between the conical upper seat 1 and the conical lower seat 2. The sealing ring 13 between the conical upper seat 1 and the conical lower seat 2 can seal the connection. Finally, it can be locked and fixed by fastening the bolt seat 7. The two ends of the arc-shaped cover 5 can also be sealed and connected by the sealing strip 8, thereby realizing the quick disassembly and maintenance of the grinding inner liner 10 at the grinding tank 9, and thus realizing the efficient cleaning and maintenance of the crushing main roller 3. The above is the complete working principle of this utility model.
