DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside”, etc., are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. This embodiment is written in a progressive manner.

[0032] like Figures 1 to 5 As shown, the high-speed tablet press for drug manufacturing of the present invention comprises a feed tray 1, a plurality of feeding mechanisms 2 and a plurality of pressing mechanisms 3, the number of the feeding mechanisms 2 and the pressing mechanisms 3 are the same, and the feeding mechanism 2 is located between two adjacent pressing mechanisms 3, the pressing mechanism 3 is located above the feed tray 1, the plurality of feeding mechanisms 2 and the plurality of pressing mechanisms 3 are distributed in a ring shape, and the center of the ring shape coincides with the vertical axis of the feed tray 1;

[0033] The feed tray 1 is provided with a plurality of hole groups, each hole group being composed of a plurality of die holes 4;

[0034] The pressing mechanism 3 includes a first movable table 5 capable of vertical reciprocating movement, a second movable table 6 is slidably provided at the bottom of the first movable table 5, the sliding track of the second movable table 6 is arc-shaped, and the center of the arc coincides with the axis of the feed tray 1, and a plurality of mold columns 7 are provided at the bottom of the second movable table 6, the number of the plurality of mold columns 7 is consistent with the number of the plurality of mold holes 4 in each hole group, and their positions correspond to each other.

[0035] Specifically, the feed tray 1 is used to carry the hole group thereon to perform continuous circular motion, so that the hole group can be continuously transported to the bottom of the pressing mechanism 3, so that the mold column 7 can be inserted into the mold hole 4 by repeatedly moving the pressing mechanism 3 downward. The feeding mechanism 2 is used to supply the pharmaceutical granular raw material to the feed tray 1, and the raw material supplied by the feeding mechanism 2 can fill the mold hole 4 on the feed tray 1. The first movable platform 5 can move in the vertical direction, so as to control the second movable platform 6 and the mold column 7 to move in the vertical direction, so as to facilitate the mold column 7 to approach or move away from the mold hole 4, so that the position of the mold column 7 in the vertical direction can be adjusted. At the same time, due to the second movable platform 6 The movable table 6 can slide in an arc on the first movable table 5, and the center of the arc coincides with the axis of the feed tray 1. Therefore, the position of the mold column 7 in the horizontal direction can be adjusted with the help of the second movable table 6, and the moving trajectory of the second movable table 6 and the mold column 7 coincides with the rotation trajectory of the feed tray 1. When the moving speed of the second movable table 6 is consistent with the rotation speed of the feed tray 1, the mold column 7 and the feed tray 1 move synchronously and are relatively stationary. At this time, if the mold column 7 is moved downward, the purpose of dynamically extruding the granular raw material in the mold hole 4 by the mold column 7 can be achieved. The up and down movement of the first movable table 5 and the arc movement of the second movable table 6 are in a reciprocating motion state.

[0036] When in use, the feeding mechanism 2 continuously conveys the pharmaceutical granular raw material to the die holes 4 on the feed tray 1 and fills the die holes 4 with the raw material, the feed tray 1 continues to rotate and conveys the die holes 4 and the raw material to the bottom of the pressing mechanism 3, at this time, the second movable table 6 synchronously moves in an arc shape, the second movable table 6 drives the die column 7 to move, the die column 7 moves synchronously with the feed tray 1 and is relatively stationary, at this time, the first movable table 5 is pushed to move downward, the first movable table 5 drives the second movable table 6 and the die column 7 thereon to move downward synchronously, the multiple die columns 7 on the second movable table 6 are respectively inserted into the multiple die holes 4 in a group of holes, so that the die column 7 extrude and mold the raw material in the die hole 4, when the raw material is formed into a sheet, the first movable table 5 moves upward and separates the die column 7 from the die hole 4, the first movable table 5 and the second movable table 6 are reset, the sheet medicine in the die hole 4 is taken out and prepared for the next tableting work, because the feed tray 1 continues to rotate, and the raw material on the feed tray 1 is repeatedly tableted by multiple groups of pressing mechanisms 3, thereby realizing the high-speed tableting processing of the medicine.

[0037] By means of the continuous annular movement of the feed tray 1 and the multiple die holes 4 thereon, the multiple groups of pressing mechanisms 3 can perform continuous and rapid tableting and forming processing on the drug granular raw materials in the die holes 4, thereby improving the continuity of the tableting work, thereby greatly improving the efficiency of the drug tableting process. At the same time, the tableting process is carried out in an automated manner, which greatly simplifies the operation method and saves manpower.

[0038] Preferably, Figure 3 to Figure 4 As shown, the feed tray 1 is composed of a swivel 8 and a plurality of arc-shaped support plates 9. The plurality of arc-shaped support plates 9 are on the same circle. Discharge gaps are left between the plurality of arc-shaped support plates 9. The swivel 8 is slidably mounted on the plurality of arc-shaped support plates 9, and the mold hole 4 passes through the swivel 8.

[0039] Specifically, the swivel 8 can rotate on the arc-shaped support plate 9, and the arc-shaped support plate 9 supports the swivel 8. When the tableting process is performed, the upper surface of the arc-shaped support plate 9 blocks the bottom of the die hole 4. At this time, the die column 7 extrude and molds the raw material in the die hole 4. After the raw material is formed, it moves synchronously with the feed tray 1 on the arc-shaped support plate 9. When the raw material moves to the gap between two adjacent arc-shaped support plates 9, the raw material naturally falls off through the bottom of the die hole 4, thereby realizing automatic discharge.

[0040] The number of arc-shaped support plates 9 is consistent with the number of pressing mechanisms 3. Therefore, every time a group of pressing mechanisms 3 completes the tableting process, the formed raw material can fall and be discharged through the gap between two adjacent arc-shaped support plates 9. In actual use, in order to avoid the tablets getting stuck in the die hole 4, the tablets can be blown out of the die hole 4 by blowing.

[0041] Preferably, Figure 3 As shown, the inner wall and the outer wall of the swivel 8 are both provided with a rib 10, the swivel 8 and the rib 10 slide relative to each other, the rib 10 is fixed on the arc-shaped support plate 9, a plurality of inclined push plates 11 are obliquely provided on the upper surface of the swivel 8, and the plurality of inclined push plates 11 are distributed in a ring shape, a plurality of openings 12 are opened on the rib 10 on the outer side of the swivel 8, and the inclined push plates 11 pass through the openings 12 and extend to the outer side of the rib 10;

[0042] The swivel ring 8 and the rib 10 are in contact with each other and slide relative to each other.

[0043] Specifically, when the feeding mechanism 2 introduces the pharmaceutical granular raw materials into the feed tray 1, the excess raw materials will be blocked by the inclined push plate 11. Since the inclined push plate 11 is inclined, the inclined push plate 11 can guide the excess raw materials along its inclined surface and opening 12 to the collecting mechanism outside the retaining edge 10, thereby facilitating the cleaning and collection of the excess raw materials on the feed tray 1. At the same time, due to the obstruction of the inclined push plate 11, a small amount of raw materials will always be intercepted on the side wall of the inclined push plate 11. In this way, when the unfilled die hole 4 moves to the position of the inclined push plate 11, the raw materials near the inclined push plate 11 can be filled into the die hole 4, so that the inside of the die hole 4 is filled with raw materials, avoiding unqualified tablets due to insufficient raw material filling.

[0044] The two ribs 10 can block the raw materials on the feed tray 1 to prevent the raw materials from scattering outside the feed tray 1 , and the ribs 10 can support the inclined push plate 11 at the same time.

[0045] Preferably, Figure 5 As shown, it also includes a top beam 13, each first moving platform 5 is vertically slidably installed on the top beam 13, the top beam 13 and the first moving platform 5 are connected by a cylinder 14, and a plurality of second moving platforms 6 are connected to each other. A rotating column 15 is rotatably provided at the bottom of the top beam 13, and the cross-section of the rotating column 15 is square. The rotating column 15 passes through a rotating disk 16 and slides relatively.

[0046] The rotating column 15 is provided with a transmission mechanism, and the transmission mechanism is used to drive the rotating column 15 to rotate.

[0047] Specifically, the top beam 13 can support multiple groups of pressing mechanisms 3, and the cylinder 14 can push the first movable platform 5 to move up and down, thereby providing power for the first movable platform 5. When the first movable platform 5 and the second movable platform 6 move up and down, the second movable platform 6 can slide on the rotating column 15, and the transmission mechanism provides rotational power for the rotating column 15. Due to the shape limitation of the rotating column 15, the rotating column 15 can drive the second movable platform 6 to move in an arc, thereby providing vertical and horizontal power for the mold column 7.

[0048] Preferably, Figure 6 As shown, the transmission mechanism includes a turntable 16, the bottom of the rotating column 15 slides through the turntable 16, a guide rack 18 is arranged on the circumferential outer wall of the turntable 16, the projection of the guide rack 18 on the horizontal plane is arc-shaped, both ends of the guide rack 18 are arranged as semicircular arc surfaces, and the axis of the semicircular arc surface is horizontal, teeth are arranged on the outer wall of the guide rack 18, and a guide groove 17 is opened on the outer wall of the turntable 16 outside the guide rack 18, and the shape of the guide groove 17 is consistent with the appearance of the guide rack 18;

[0049] A connecting shaft 19 is slidably provided in the guide groove 17, and the axial direction of the connecting shaft 19 is along the radial direction of the turntable 16. A first gear 20 and a second gear 21 are provided on the connecting shaft 19, and the first gear 20 is meshed with the teeth on the guide rack 18. A gear ring 22 is provided on the upper surface of the feed disc 1, and the second gear 21 is meshed with the gear ring 22. The connecting shaft 19 is fixedly connected to the top beam 13 by a connecting plate 23.

[0050] Specifically, the feed plate 1 can drive the gear ring 22 to rotate, and the gear ring 22 can drive the first gear 20 to rotate through the second gear 21 and the connecting shaft 19. Since the first gear 20 is engaged with the teeth on the guide rack 18, the first gear 20 can push the guide rack 18 to move, and the guide rack 18 drives the turntable 16 to rotate, so that the turntable 16 drives the rotating column 15 to rotate, which is convenient for providing rotational power for the rotating column 15.

[0051] The guide groove 17 can limit the connection shaft 19 and the first gear 20, so that the first gear 20 and the teeth on the guide rack 18 are always in meshing state. When in use, when the first gear 20 and the teeth on the upper surface of the guide rack 18 are meshed and move relative to each other, the mold column 7 moves down and extrude and shape the raw material in the mold hole 4, and then the mold column 7 moves up to the initial position. When the first gear 20 and the teeth on the lower surface of the guide rack 18 are meshed and move relative to each other, the mold column 7 is reset on the horizontal plane. When the gear 20 is meshed with the teeth of the semicircular arc surfaces at both ends of the guide rack 18, the mold column 7 and the mold hole 4 are in a separated state, thereby avoiding the change in the transmission ratio of the rotation speed of the turntable 16 at this position, which causes the mold column 7 and the mold hole 4 to move at inconsistent speeds and cause the mold column 7 and the mold hole 4 to collide with each other. When the first gear 20 moves on the upper and lower surfaces of the guide rack 18, the turntable 16 is displaced in the vertical direction. At this time, the turntable 16 slides on the rotating column 15, and the connecting plate 23 can support the connecting shaft 19.

[0052] Preferably, the interior of the turntable 16 is hollow, and a spring is disposed inside the turntable 16 . The spring is connected to the rotating column 15 , and the spring provides an upward elastic pulling force to the turntable 16 .

[0053] Specifically, by setting the turntable 16 to a hollow state, the weight of the turntable 16 can be reduced, and with the help of the pulling force of the spring on the turntable 16, the turntable 16 can be easily slid normally on the turntable 15, avoiding the first gear 20 being unable to push the guide rack 18 to move in the vertical direction due to the heavy weight of the turntable 16.

[0054] Preferably, Figure 7As shown, the feeding mechanism 2 includes a conveying barrel 24, which is composed of two transverse cylinders, which are distributed up and down and are connected. A core shaft 25 is rotatably provided in each transverse cylinder, a spiral plate 26 is provided on one core shaft 25, and a plurality of long plates 27 are provided on the other core shaft 25. The length direction of the long plate 27 is along the axial direction of the core shaft 25, and the spiral plate 26 is located above the long plate 27.

[0055] A wide unloading groove 28 is connected to the horizontal cylinder located on the lower side, and a feeding channel 29 is provided on the horizontal cylinder located on the upper side. The ends of the two core shafts 25 extend to the outside of the two horizontal cylinders respectively, and a third gear 30 is provided on the end of the core shaft 25. The two third gears 30 are meshed with each other. A first motor 31 is provided on the conveying barrel 24, and the first motor 31 is transmission-connected to a core shaft 25.

[0056] Specifically, the raw material is introduced into one side of the upper horizontal cylinder through the feed channel 29, and the first motor 31 can drive the two core shafts 25, a spiral plate 26 and multiple long plates 27 to rotate through two third gears 30. The spiral plate 26 can horizontally transport the raw material on one side of the upper horizontal cylinder, so that the raw material is distributed in the horizontal direction, and the raw material falls between two adjacent long plates 27 in the lower horizontal cylinder. As the multiple long plates 27 rotate, the raw material between two adjacent long plates 27 can be discharged to the feed tray 1 through the unloading wide groove 28, thus realizing the loading work. At the same time, since the raw material is transported with the help of the space between the two adjacent long plates 27, the raw material can be easily scattered in a planar shape on the feed tray 1, so that the raw material is evenly distributed, thereby facilitating the raw material to enter the multiple mold holes 4.

[0057] Preferably, Figure 4 As shown, a tooth groove 32 is provided at the bottom of the feed tray 1 , a second motor 33 is provided on the inner side rib 10 of the feed tray 1 , a fourth gear 34 is provided at the output end of the second motor 33 , and the fourth gear 34 meshes with the teeth in the tooth groove 32 .

[0058] Specifically, the second motor 33 can drive the feed tray 1 to rotate through the teeth in the tooth groove 32 of the fourth gear 34, thereby driving the equipment to operate.

[0059] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
