For example, a process, method, system, product or apparatus that includes a series of steps or units is not necessarily limited to those steps or units expressly listed, but may include other steps or units not expressly listed or inherent to such process, method, product or apparatus.

[0030] like Figure 1-10 The powder coating grinding equipment shown includes a cylindrical grinding jar 1, a limiting frame 5 is rotatably connected inside the grinding jar 1, the limiting frame 5 is constrained by the grinding jar 1 and rotates around the axis of the grinding jar 1, and a main roller 3 and a plurality of auxiliary rollers 4 are rotatably connected to the bottom of the limiting frame 5. These auxiliary rollers 4 are arranged equidistantly around the main roller 3. The specific structure of the limiting frame 5 includes a coaxial upper planetary frame 510 and a lower planetary frame 520, and the main part of the auxiliary roller 4 is a driven roller shaft 401. The upper and lower ends of the driven roller shaft 401 are rotatably connected to the upper planetary frame 510 and the lower planetary frame 520 respectively. In order to allow each driven roller shaft 4 01 can perform the same rotational connection, and upper shaft holes 512 with the same number and position as the auxiliary roller 4 will be opened on the upper planetary frame 510, and lower shaft holes 522 with the same number and position as the auxiliary roller 4 will be opened on the lower planetary frame 520. The upper and lower ends of the driven roller shaft 401 have coaxial end shafts 402, and the end shaft 402 is obviously smaller than the diameter of the driven roller shaft 401. The upper end shaft 402 passes through the upper shaft hole 512 and is fixedly connected to a retaining ring 404, which can suppress the upper end shaft 402 from moving downward, and the lower end shaft 402 passes through the lower shaft hole 522 and is fixedly connected to the driven gear 403 for connecting the rotational power.

[0031] The upper end of the base 120 is fixedly connected to the upper cover 110 through the tank body 130. The center of the upper cover 110 passes downward, and the inner wall of the upper cover 110 is provided with an upper slide groove 113, which cooperates with the edge of the upper planetary frame 510 to form a rotating pair. The inner wall of the upper planetary frame 510 also has a slip ring 511 extending upward, and a ring slide groove 112 is provided on the inner top surface of the upper cover 110, which cooperates with the slip ring 511 to form a rotating pair, further improving the stability of the rotation of the upper planetary frame 510. The top surface of the upper cover 110 is fixedly connected to the funnel 111, which facilitates the material to enter the tank body 130 from the opening of the upper cover 110. The inner wall of the base 120 is also provided with a lower slide groove 123, which cooperates with the edge of the lower planetary frame 520 to form a rotating pair. In this way, the upper and lower ends of the limit frame 5 can be kept very stable, and the base 120 is fixedly connected to the bracket 124, which can allow the grinding jar 1 to be suspended at a certain height from the ground to avoid direct contact with the ground.

[0032] A linkage frame 530 is fixedly connected between the upper planetary frame 510 and the lower planetary frame 520 to ensure the synchronization of the upper planetary frame 510 and the lower planetary frame 520. The number of linkage frames 530 is the same as that of the auxiliary rollers 4, so that the linkage frames 530 can be arranged at intervals between the auxiliary rollers 4, and the center of each linkage frame 530 has an inwardly protruding diverter cone 531 for guiding materials in different directions. The diverter cone 531 is located between adjacent driven rollers 401 to fill the gap between adjacent driven rollers 401. The material is transported through the smaller gap. The moving parts can be ground and refined more fully. The main part of the main roller 3 is the active conical shaft 301. The active conical shaft 301 is conical, with a small diameter at the upper end and a large diameter at the lower end. The outer side of the active conical shaft 301 has evenly distributed roller teeth 302, and the roller teeth 302 also gradually become smaller from top to bottom. Moreover, both sides of each linkage frame 530 have guide edges 532 close to the inner wall of the tank body 130, which are used to scrape the material adhered to the inner wall of the tank body 130 back to between the driven roller shaft 401 and the active conical shaft 301, thereby reducing the residue of the ground material.

[0033] The lower end of the driving cone shaft 301 has a coaxial driving gear 304, which is significantly larger than the driven gear 403. A coaxial spindle hole 521 is also provided in the center of the lower planetary carrier 520. The lower end of the driving cone shaft 301 has a coaxial central shaft 303, and the central shaft 303 passes through a portion of the spindle hole 521 and is keyed to the driving gear 304. The central shaft 303 cooperates with the spindle hole 521 to form a rotating pair. The lower end of the driven roller shaft 401 has a driven gear 403, and all the driven gears 403 are engaged with the driving gear 304. The bottom of the grinding jar 1 is a base 120, and the inner wall of the base 120 has an inner gear ring 122, which is engaged with all the driven gears 403 at the same time, actually forming a planetary gear structure.

[0034] A driver 2 is provided at the bottom of the base 120 for driving the main roller 3 to rotate. A discharge hole 121 is provided in the center of the base 120. The diameter of the discharge hole 121 is larger than the diameter of the central axis 303. The driver 2 includes a motor 201 and a reducer 202 fixedly connected to the bottom surface of the base 120. The output end of the motor 201 is connected to the input end of the reducer 202. The lower end of the central axis 303 can pass through the discharge hole 121 and be connected to the output end of the reducer 202, thereby driving all the auxiliary rollers 4 to rotate synchronously through the main roller 3.

[0035] Working principle: When in use, the raw materials enter from the funnel 111 at the upper end of the grinding tank 1, and are squeezed and refined between the main roller 3 and the auxiliary roller 4 that rotate relatively. Since the main part of the main roller 3 is conical, the gap that the material can pass through becomes smaller as it goes down, and the degree of refinement becomes higher. The finished product finally obtained by grinding is discharged from the discharge hole 121.

[0036] The above describes the basic principles, main features, and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above-described embodiments. The above-described embodiments and the specification merely illustrate the principles of the present application. Various changes and improvements may be made to the present application without departing from the spirit and scope of the present application. These changes and improvements fall within the scope of the present application for which protection is sought.
