And discharging the screened propolis powder through a discharge hole.

The milling mechanism comprises an installation sleeve, a support, an annular milling block, a horizontal plate, an elastic telescopic rod and an annular plate. The mounting sleeve is vertically and slidably mounted on the main shaft, a horizontal support is fixedly mounted on the outer side wall of the mounting sleeve, and an annular grinding block which is coincident with the axis of the working cavity is fixedly mounted at the outer end of the support. The outer side wall of the annular grinding block is matched with the inner wall of the working box. The top surface of the annular grinding block is arc-shaped. The installation cover top surface fixed mounting has the horizontal plate, and the even fixed mounting in main shaft circumference has the vertical elastic telescopic rod of a plurality of on the horizontal plate, and the horizontal fixed mounting in elastic telescopic rod flexible section top has the annular plate with the main shaft axis coincidence, and the annular plate rotates to be installed at the apron lower surface. The upper surface of the horizontal plate is fixedly provided with a first magnet block, and the lower surface of the cover plate is fixedly provided with a second magnet block. The main shaft drives the mounting sleeve, the support, the annular grinding block, the horizontal plate, the elastic telescopic rod, the annular plate and the first magnet block to synchronously rotate in the rotating process. The blocky propolis falls to the top surface of the annular grinding block and then slides to a position between the outer side wall of the annular grinding block and the inner wall of the working box, and the blocky propolis is ground through the horizontal rotation of the annular grinding block. When the first magnet block is close to the second magnet block, the first magnet block and the second magnet block generate mutual repulsion, the horizontal plate, the mounting sleeve, the support and the annular grinding block integrally move downwards, and the elastic telescopic rod is stretched. When the first magnet block is far away from the second magnet block, the mutual repulsion force between the first magnet block and the second magnet block disappears, and the horizontal plate, the mounting sleeve, the support and the annular grinding block are driven to integrally move upwards to restore to the initial height under the action of the elastic force of the elastic telescopic rod. Along with the continuous rotation of first magnet piece, annular grinding block produces reciprocal reciprocating and reciprocates in the horizontal rotation to the area of work box inner wall and annular grinding block lateral wall contact has been increased. Because can be with heat transfer to the work box inner wall after the annular grinding piece frictional heating on, the increase of the area of work box inner wall and annular grinding piece contact can increase the radiating effect of work box inner wall, and then increased the radiating effect of annular grinding piece, avoided propolis powder to be heated the back viscidity increase and the adhesion on annular grinding piece surface.

Screening mechanism includes circular slab, annular sieve, first spring, third magnet piece, horizon bar, fourth magnet piece and sealing ring. The circular plate is slidably mounted on the main shaft at a position below the annular grinding block. The outer wall of the circular plate is horizontally and fixedly provided with an annular sieve plate which is coincided with the axis of the working cavity. An annular groove is formed in the inner side wall of the working box, and the annular sieve plate is in sliding fit with the annular groove. A plurality of first springs are vertically arranged between the bottom surface of the annular sieve plate and the bottom surface of the annular groove. The bottom surface of the circular plate is uniformly and fixedly provided with a plurality of third magnet blocks around the main shaft. And a horizontal rod is fixedly arranged on the main shaft below the circular plate, and a fourth magnet block is fixedly arranged on the horizontal rod corresponding to the third magnet block. And a sealing ring which is vertically matched with the inner side wall of the working box in a sliding manner is horizontally and fixedly arranged on the upper surface of the annular sieve plate. The propolis powder after being milled falls onto the sealing ring from the position between the inner wall of the working box and the outer side wall of the annular milling block and slides onto the annular sieve plate, the propolis powder after being fully milled falls after passing through sieve pores on the annular sieve plate, and part of the propolis powder can be adhered to the inner wall of the sieve pores to block the sieve pores. When the main shaft rotates, the horizontal rod and the fourth magnet block are driven to rotate; when the fourth magnet block and the third magnet block approach each other, an attractive force is generated between the fourth magnet block and the third magnet block, and the circular plate, the annular sieve plate and the third magnet block move downward against the elastic force of the first spring. When the fourth magnet block and the third magnet block are far away from each other, the circular plate, the annular sieve plate and the third magnet block are pushed to move upwards under the action of the elastic force of the first spring until the annular sieve plate impacts the top surface of the annular groove; the annular sieve plate generates vibration when impacting the top surface of the annular groove, so that the propolis powder blocked in the sieve holes is vibrated to fall. Along with the continuous rotation of the horizontal rod and the fourth magnet block, the annular sieve plate periodically moves up and down and periodically collides with the top surface of the annular groove, and the propolis powder blocked in the sieve hole is continuously vibrated down.

A second spring is horizontally arranged between the fifth magnet block and the first supporting block. And a plurality of sixth magnet blocks are uniformly and fixedly arranged in the position, corresponding to the fifth magnet block, in the side plate of the working box along the circumferential direction of the working cavity. In the horizontal rotation process of the annular grinding block, the heat generated by friction with the inner side wall of the working box is partially dissipated into the heat dissipation groove. When the sixth magnet block and the fifth magnet block are close to each other, mutual repulsion is generated between the sixth magnet block and the fifth magnet block, the fifth magnet block overcomes the elastic action of the second spring and slides along the heat dissipation groove, and hot air in the heat dissipation groove is extruded out of the heat dissipation groove. When the sixth magnet block and the fifth magnet block are far away from each other, the mutual repulsion force between the sixth magnet block and the fifth magnet block disappears, the fifth magnet block is pushed by the elastic force of the second spring to slide along the heat dissipation groove to be restored to the original position, and air outside the heat dissipation groove is sucked into the heat dissipation groove; thereby accomplishing the circulation of air in the radiating groove and improving the heat dispersion of the annular grinding block.

As a preferred technical scheme of the invention, a plurality of air grooves which are arranged along the radial direction of the working cavity are uniformly arranged on the inner side wall of the working box between the annular groove and the discharge hole along the circumferential direction of the working cavity. An air pump communicated with the air groove is fixedly arranged on the outer side wall of the working box. An L-shaped pipe is arranged in the air tank. The vertical section of the L-shaped pipe is positioned right below the annular sieve plate. A cylinder which is coincident with the axis of the main shaft is vertically and fixedly arranged on the bracket, and a material guide plate which is positioned between the top surface of the annular grinding block and the material guide ring is fixedly arranged at the top of the cylinder. The guide plate is annular and the longitudinal section of the guide plate is arc-shaped. During operation, blow to the gas tank through the air pump, the air current blows to annular sieve from bottom to top after passing through L type pipe to the propolis powder that will block up in the sieve mesh blows out the sieve mesh, blows out the propolis powder of sieve mesh and moves along drum and stock guide under the air current effect, and finally falls to annular and mills between piece lateral wall and the work box inner wall and carry out the secondary and mill. The horizontal fixed mounting in drum bottom has the sponge ring with the circular plate upper surface laminating to when guaranteeing that the circular plate follows the support and reciprocates and the circular plate reciprocates, can not produce the space between drum bottom and the circular plate upper surface, thereby avoided inside propolis powder gets into the drum.

As a preferable technical scheme of the invention, the horizontal section of the L-shaped pipe is in sliding fit in the air groove. An annular second supporting block is fixedly arranged in the air groove, and a third spring is horizontally arranged between the second supporting block and the end face of the horizontal section of the L-shaped pipe. And a seventh magnet block corresponding to the fourth magnet block in position is fixedly mounted on the outer side wall of the vertical section of the L-shaped pipe. Along with the continuous rotation of the main shaft, the horizontal rod and the fourth magnet block, a mutual repulsion force is generated between the fourth magnet block and the seventh magnet block periodically, so that the L-shaped pipe is pushed to reciprocate along the air groove periodically under the combined action of the third spring. When the L-shaped pipe reciprocates along the air groove, the air sprayed out of the top of the vertical section of the L-shaped pipe can clean the sieve holes of the annular sieve plate, so that the dredging effect is improved.

As shown in fig. 1, this embodiment provides a preparation method of a skin care product propolis extract, which includes the following steps:

The process of crushing and sieving the blocky propolis to obtain the propolis powder in the step one is completed by matching a skin care product propolis extract preparation device shown in figures 2 to 5, wherein the skin care product propolis extract preparation device comprises a working box 1 with an opening at the top, a cylindrical working cavity 2 is formed in the working box 1, and a horizontal cover plate 3 is arranged at the top of the working box 1. The top surface of the cover plate 3 is vertically and fixedly provided with a driving motor 4, and the output end of the driving motor 4 is fixedly provided with a main shaft 5 which is superposed with the axis of the working cavity 2. The main shaft 5 penetrates through the cover plate 3, the working chamber 2 and the bottom plate of the working box 1. A plurality of feed inlets 6 are uniformly arranged on the cover plate 3 around the driving motor 4. A plurality of discharge holes 7 are uniformly formed on the bottom plate of the working box 1 around the main shaft 5. A plurality of supporting legs are vertically and fixedly arranged on the lower surface of a bottom plate of the working box 1. The main shaft 5 is provided with a grinding mechanism 8 and a screening mechanism 9 from top to bottom.

The milling mechanism 8 comprises a mounting sleeve 81, a bracket 82, annular milling blocks 83, a horizontal plate 84, an elastic telescopic rod 85 and an annular plate 86. The mounting sleeve 81 is vertically and slidably mounted on the main shaft 5, a horizontal support 82 is fixedly mounted on the outer side wall of the mounting sleeve 81, and an annular grinding block 83 which is coincident with the axis of the working chamber 2 is fixedly mounted at the outer end of the support 82. The outer side walls of the ring-shaped grinding blocks 83 are fitted to the inner wall of the working box 1. The top surface of the ring-shaped grinding block 83 is curved. The top surface of the mounting sleeve 81 is fixedly provided with a horizontal plate 84, the horizontal plate 84 is uniformly and fixedly provided with a plurality of vertical elastic telescopic rods 85 along the circumferential direction of the main shaft 5, the top of the telescopic section of each elastic telescopic rod 85 is horizontally and fixedly provided with an annular plate 86 coinciding with the axis of the main shaft 5, and the annular plate 86 is rotatably arranged on the lower surface of the cover plate 3. The upper surface of the horizontal plate 84 is fixedly provided with a first magnet block 10, and the lower surface of the cover plate 3 is fixedly provided with a second magnet block 11. The main shaft 5 drives the mounting sleeve 81, the bracket 82, the annular grinding block 83, the horizontal plate 84, the elastic telescopic rod 85, the annular plate 86 and the first magnet block 10 to synchronously rotate in the rotating process. The blocky propolis falls to the top surface of the annular grinding block 83 and then slides to a position between the outer side wall of the annular grinding block 83 and the inner wall of the working box 1, and the blocky propolis is ground through the horizontal rotation of the annular grinding block 83. When the first magnet block 10 approaches the second magnet block 11, a repulsive force is generated therebetween, and the horizontal plate 84, the mounting sleeve 81, the support 82, and the ring mill block 83 move downward as a whole, and the elastic expansion bar 85 is elongated. When the first magnet block 10 is away from the second magnet block 11, the repulsive force between the two disappears, and the horizontal plate 84, the mounting sleeve 81, the bracket 82 and the ring-shaped milling block 83 are driven by the elastic force of the elastic telescopic rod 85 to move upward to return to the initial height. As the first magnet block 10 continues to rotate, the ring mill block 83 reciprocates while horizontally rotating, thereby increasing the area of the inner wall of the work box 1 in contact with the outer side wall of the ring mill block 83. Because can be with heat transfer to work box 1 inside wall behind the annular grinding piece 83 frictional heating, the area increase of work box 1 inside wall and the contact of annular grinding piece 83 can increase the radiating effect of work box 1 inside wall, and then has increased the radiating effect of annular grinding piece 83, has avoided propolis powder to be heated the back viscidity increase and the adhesion on annular grinding piece surface.

The screening mechanism 9 includes a circular plate 91, an annular screen plate 92, a first spring 93, a third magnet block 94, a horizontal rod 95, a fourth magnet block 96, and a seal ring 97. A circular plate 91 is slidably mounted on the main shaft 5 at a position below the annular grinding blocks 83. An annular sieve plate 92 which is coincident with the axis of the working cavity 2 is horizontally and fixedly arranged on the outer wall of the circular plate 91. An annular groove 12 is formed in the inner side wall of the working box 1, and the annular sieve plate 92 is in sliding fit with the annular groove 12. A plurality of first springs 93 are vertically arranged between the bottom surface of the annular sieve plate 92 and the bottom surface of the annular groove 12. The top surface of the annular groove 12 is fixedly provided with an annular rubber ring 14 so as to relieve the impact force of the top surface of the annular groove 12 on the surface of the annular sieve plate 92 and prolong the service life of the annular sieve plate 92. A plurality of third magnet blocks 94 are uniformly and fixedly mounted on the bottom surface of the circular plate 91 around the spindle 5. A horizontal rod 95 is fixedly attached to the main shaft 5 below the circular plate 91, and a fourth magnet block 96 is fixedly attached to the horizontal rod 95 at a position corresponding to the third magnet block 94. The upper surface of the annular sieve plate 92 is horizontally and fixedly provided with a sealing ring 97 which is vertically matched with the inner side wall of the working box 1 in a sliding way. The ground propolis powder falls onto the sealing ring 97 from the space between the inner wall of the working box 1 and the outer side wall of the annular grinding block 83 and slides onto the annular sieve plate 92, the propolis powder which is fully ground falls after passing through sieve holes on the annular sieve plate 92, and part of the propolis powder can be adhered to the inner wall of the sieve holes to block the sieve holes. When the main shaft 5 rotates, the horizontal rod 95 and the fourth magnet block 96 are driven to rotate; when the fourth magnet piece 96 and the third magnet piece 94 approach each other, an attractive force is generated therebetween, and the circular plate 91, the annular sieve plate 92, and the third magnet piece 94 move downward against the elastic force of the first spring 93. When the fourth magnet block 96 and the third magnet block 94 are away from each other, the circular plate 91, the annular sieve plate 92 and the third magnet block 94 are pushed to move upwards by the elastic force of the first spring 93 until the annular sieve plate 92 impacts the top surface of the annular groove 12; the annular sieve plate 92 vibrates when it hits the top surface of the annular groove 12, thereby vibrating down the propolis powder blocked in the sieve holes. With the continuous rotation of the horizontal rod 95 and the fourth magnet block 96, the annular sieve plate 92 periodically moves up and down and periodically collides with the top surface of the annular groove 12, and the propolis powder blocked in the sieve hole is continuously shaken off.

A plurality of radiating grooves 87 radially arranged along the annular grinding block 83 are uniformly formed in the inner side wall of the annular grinding block along the circumferential direction of the inner side wall, an annular first supporting block 88 is fixedly installed in each radiating groove 87, and a fifth magnet block 89 is matched with the radiating grooves 87 in an sliding mode. A second spring 810 is horizontally installed between the fifth magnet block 89 and the first support block 88. A plurality of sixth magnet blocks 15 are uniformly and fixedly arranged on the inner side of the side plate of the working box 1 corresponding to the position of the fifth magnet block 89 along the circumferential direction of the working cavity 2. During the horizontal rotation of the ring-shaped grinding block 83, part of the heat generated by the friction with the inner side wall of the work box 1 is dissipated into the heat dissipation groove 87. When the sixth magnet piece 15 and the fifth magnet piece 89 approach each other, a mutual repulsive force is generated therebetween, and the fifth magnet piece 89 slides along the heat dissipation groove 87 against the elastic force of the second spring 810, and pushes out the hot air in the heat dissipation groove 87 out of the heat dissipation groove 87. When the sixth magnet piece 15 and the fifth magnet piece 89 are away from each other, the mutual repulsion force between the two disappears, the elastic force of the second spring 810 pushes the fifth magnet piece 89 to slide along the heat dissipation groove 87 and return to the original position, and the air outside the heat dissipation groove 87 is sucked into the heat dissipation groove 87; thereby completing the circulation of air in the heat dissipation groove 87 and improving the heat dissipation performance of the ring mill block 83.

A plurality of air grooves 16 which are radially arranged along the working cavity 2 are uniformly arranged on the inner side wall of the working box 1 along the circumferential direction of the working cavity 2 and between the annular groove 12 and the discharge hole 7. An air pump 17 communicated with the air groove 16 is fixedly arranged on the outer side wall of the working box 1. An L-shaped pipe 18 is smoothly matched with the water in the air tank 16. The vertical section of the L-shaped pipe 18 is located directly below the annular screen deck 92. A cylinder 19 which is coincident with the axis of the main shaft 5 is vertically and fixedly arranged on the bracket 82, and a material guide plate 20 which is positioned between the top surface of the annular grinding block 83 and the material guide ring 13 is fixedly arranged at the top of the cylinder 19. The guide plate 20 is ring-shaped and the longitudinal section of the guide plate 20 is arc-shaped. During operation, the air pump 17 blows air into the air groove 16, the air flow blows towards the annular sieve plate 92 from bottom to top after passing through the L-shaped pipe 18, so that propolis powder blocked in the sieve holes is blown out of the sieve holes, the propolis powder blown out of the sieve holes moves along the cylinder 19 and the guide plate 20 under the action of the air flow, and finally falls between the outer side wall of the annular grinding block 83 and the inner side wall of the working box 1 for secondary grinding. The bottom of the cylinder 19 is horizontally and fixedly provided with a sponge ring 21 attached to the upper surface of the circular plate 91, so that when the circular plate 91 moves up and down along with the bracket 82 and the circular plate 91 moves up and down, no gap is generated between the bottom of the cylinder 19 and the upper surface of the circular plate 91, and propolis powder is prevented from entering the cylinder 19. An annular second supporting block 22 is fixedly installed in the air groove 16, and a third spring 23 is horizontally installed between the second supporting block 22 and the end face of the horizontal section of the L-shaped pipe 18. The seventh magnet block 24 corresponding to the fourth magnet block 96 is fixedly mounted on the outer side wall of the vertical section of the L-shaped pipe 18. As the main shaft 5, the horizontal rod 95 and the fourth magnet block 96 continue to rotate, the fourth magnet block 96 periodically generates a mutual repulsive force with the seventh magnet block 24, so that the L-shaped tubes 18 are periodically pushed to reciprocate along the air slots 16 under the cooperation of the third springs 23. When the L-shaped pipe 18 reciprocates along the air groove 16, the air sprayed out of the top of the vertical section of the L-shaped pipe 18 can clean all sieve holes of the annular sieve plate 92, and the dredging effect is improved.

When the skin care product propolis extract preparation device works, the block propolis is fed into the working cavity 2 through the feed inlet 6. The main shaft 5 is driven to rotate by the driving motor 4, and the main shaft 5 drives the annular grinding block 83 to generate friction force with the inner side wall of the working box 1, so that the blocky propolis is ground. Screening the milled propolis powder through an annular sieve plate 92; the screened propolis powder is discharged through a discharge port 7. During operation, the air pump 17 blows air into the air groove 16, the air flow blows towards the annular sieve plate 92 after passing through the L-shaped pipe 18, so that propolis powder blocked in the sieve holes blows out of the sieve holes, the propolis powder blown out of the sieve holes moves along the cylinders 19 and the guide plate 20 under the action of the air flow, and finally falls between the outer side wall of the annular grinding block 83 and the inner side wall of the working box 1 for secondary grinding.
