[0039] like Figure 1-5 As shown, the present invention provides a tablet press, which comprises: an operating table 1 and a feeding and forming mechanism;

[0040] The feeding and forming mechanism includes: a material storage box 3, a pressing piece 4, a sealing cover plate 5 and a support plate 6; wherein,

[0041] At least one row of mold cavities 2 is evenly and vertically arranged on the operating table 1, and a support plate 6 capable of sealing a row of mold cavities 2 is horizontally and movably arranged at the bottom end of the operating table 1. A storage box 3 with raw materials stored inside is horizontally and liftably arranged above the operating table 1, and a row of tubular pressing pieces 4 corresponding to a row of mold cavities 2 and capable of extending into the mold cavities 2 to discharge materials into the mold cavities 2 are vertically and fixedly arranged at the bottom end of the storage box 3. The bottom opening of each pressing piece 4 can be lifted and lowered to be provided with a sealing cover plate 5 that can cover the opening to cooperate with the pressing piece 4 to press the raw materials in the mold cavity 2.

[0042] In the above scheme, the support plate 6 is moved so that the support plate 6 can pass through a row of the mold cavities 2 to seal, the storage box 3 is driven to descend in the vertical direction so that the bottom end portion of a row of pressed pieces 4 on it extends into a row of the mold cavities 2, and a row of the sealing cover plates 5 is driven to descend in the vertical direction so that the sealing cover plates 5 leave the pressing pieces 4 so that the bottom ends of the pressing pieces 4 are exposed. Since a row of the pressing pieces 4 is connected to the interior of the storage box 4, the raw materials in the storage box 4 enter the mold cavities 2 through a row of the pressing pieces 4 to seal the raw materials in the mold cavities 2. Carry out loading. When loading is completed, drive a row of the sealing cover plates 5 to rise to the openings of a row of the pressing pieces 4 to seal the openings at their bottom ends, and drive the storage box 3 to drive a row of the pressing pieces 4 and the sealing cover plates 5 covering the openings at their bottom ends to descend together to extrude the raw materials in the mold cavity 2 for compression molding. After the processing and molding is completed, move the support plate 6 to separate the movable plate 6 from the bottom openings of a row of the mold cavities 2, so that the processed and molded products are discharged from the bottom opening of the mold cavity 2 under the action of their own gravity, thereby realizing the function of automatic unloading.

[0043] Therefore, the functions of automatic loading and unloading can be realized through the loading and forming mechanism, and during the loading process, no excess raw materials will be generated on the surface of the operating table 1, which on the one hand improves the utilization rate of the raw materials, and on the other hand prevents the raw materials from being spilled on the operating table 1 during the loading process, which will cause the staff to need to clean up later.

[0044] In addition, a vibration motor can be fixedly installed on the side wall of the material storage box 3, so that the raw materials in the material storage box 3 can fall into each of the pressing pieces 4 through the vibration motor, thereby achieving a better discharge effect. A material injection port 20 connected to the interior of the material storage box 3 is also fixedly installed on the top side wall of the material storage box 3, so that the material storage box 3 can be replenished.

[0045] In a preferred embodiment of the present invention, the tablet press further comprises a belt conveyor 15 for receiving and feeding materials; the belt conveyor 15 comprises: a feeding roller, a feeding belt and a feeding motor, wherein,

[0046] Support plates are vertically fixed at the bottom ends of the operating table 1 located at both ends of a row of mold cavities 2, and rotatable feed rollers are horizontally and spaced apart between the two support plates. The two feed rollers are connected together through the feed belt transmission, and the end of any one of the feed rollers is coaxially connected to the feed motor horizontally fixed on the support plate through a coupling.

[0047] In the above scheme, the feeding motor is started to drive the feeding roller to rotate, thereby driving the feeding belt to run in the horizontal direction. The running feeding belt causes the products processed and formed in the mold cavity 2 of the operating table 1 to fall onto the feeding belt under the action of its own gravity, and the formed products are transported by the feeding belt.

[0048] In a preferred embodiment of the present invention, the tablet press further comprises: a receiving box 19; wherein,

[0049] A material receiving box 19 with an upward opening is horizontally provided beside the belt conveyor 15 , and the opening of the material receiving box 19 is located below the discharge end of the belt conveyor 15 .

[0050] In the above scheme, the molded products received from the mold cavity 2 of the operating table 1 are transported to its unloading end by the belt conveyor 15, and the processed and molded products fall into the receiving box 19 from the unloading end, so that the processed and molded products are collected in the receiving box 19.

[0052] A rotating shaft 1402 located next to a row of the mold cavities 2 is horizontally and rotatably arranged between the two support plates, and at least two gears 1403 are spaced apart and coaxially fixed on the rotating shaft 1402. Two rack plates 1401 meshing with the two gears 1403 are spaced apart and horizontally fixed on the lower surface of the support plate 6. The end of the rotating shaft 1402 is coaxially connected to a moving motor 1404 horizontally fixed on the support plate through a coupling.

[0053] In the above scheme, when in use, the moving motor 1404 is started to drive the rotating shaft 1402 to rotate, and during the rotation process, the gear 1403 and the rack plate 1401 on the support plate 6 are engaged, thereby driving the support plate 6 to move in the horizontal direction to achieve the blocking of a row of the mold cavities 12 or the unblocking of a row of the mold cavities 12. When the support plate 6 moves and separates from a row of the mold cavities 12 to unblock them, the bottom end of the mold cavity 12 is opened, so that the molded product falls from the mold cavity 12 to the belt conveyor 15 under the action of its own gravity, thereby realizing the function of automatic unloading.

[0054] In a preferred embodiment of the present invention, two slide rails 17 with a "convex" structure are horizontally fixed at the bottom end of the operating table 1 located at both ends of a row of the mold cavities 2, and the upper end surface of the support plate 6 attached to the operating table 1 is partially recessed inward to form two slide grooves 18 that are compatible with the two slide rails 17 and slidably connected to them.

[0055] In the above scheme, the support plate 6 can be slidably assembled on the slide rail 17 on the operating table 1 through the slide groove 18, so that the slide rail 17 and the slide groove 18 can ensure that the support plate 6 moves smoothly and reliably in the horizontal direction, thereby realizing the blocking of a row of the mold cavities 12 or the unblocking of a row of the mold cavities 12.

[0056] In a preferred embodiment of the present invention, rubber stoppers 16 are vertically fixed on both sides of the feeding belt.

[0057] In the above solution, when the feeding belt is in operation, the molded products in the mold cavity 2 of the operating table 1 are prevented from falling onto the conveyor belt 16 and sliding onto the ground along both sides of the feeding belt.

[0058] In a preferred embodiment of the present invention, the tablet press further comprises an actuator for driving all the sealing cover plates 5 to move simultaneously in the vertical direction to cover the bottom opening of each of the binders 4, the actuator comprising: a lifting plate 7, a connecting rod 10 and a cylinder 13; wherein,

A row of connecting rods 10 corresponding to a row of pressing pieces 4 are evenly and vertically fixed at the bottom end of the lifting plate 7, and the bottom end of each connecting rod 10 can pass through the interior of the corresponding pressing piece 4 and extend to the bottom thereof and is fixed with a sealing cover plate 5. The cylinder 13 is vertically fixed on the top of the bracket 8, and the free end of its piston rod is fixed on the lifting plate 7.

[0060] In the above scheme, when in use, the lifting plate 7 is driven to rise and fall in the vertical direction by starting the piston rod of the cylinder 13 to extend from or retract into its cylinder portion. During the lifting process, the lifting plate 7 can drive a row of the sealing cover plates 5 to move upward toward a row of the pressing pieces 4 through a row of the connecting rods 10 and cover the openings of a row of the pressing pieces 4 to seal them, or drive a row of the sealing cover plates 5 downward away from a row of the pressing pieces 4 to release the blockage of their openings, so as to discharge the materials into the corresponding mold cavity 2.

[0061] In addition, the cylinder 13 is a well-known technical means, so its structure and use principle will not be repeated here.

[0062] In a preferred embodiment of the present invention, a positioning ring 12 capable of limiting the position of the sealing cover plate 5 is horizontally fixedly provided inside each of the pressing pieces 4 .

[0063] In the above scheme, if Figure 3 and Figure 4 As shown, the positioning ring 12 is used to allow the sealing cover plate 5 to fit on the positioning ring 12 during the rising process. When the sealing cover plate 5 fits on the positioning ring 12, the lower surface of the sealing cover plate 5 can be on the same horizontal line as the bottom end of the pressing piece 4. When the bottom end opening of the pressing piece 4 is sealed, the raw material in the storage box 3 is prevented from leaking from the bottom end of the pressing piece 4 during the pressing process. After the sealing cover plate 5 abuts against the positioning ring 12 to seal the pressing piece 4, the storage box 3 can be moved downward to drive the pressing piece 4 to move downward in the corresponding die cavity 2 to extrude the raw material in the die cavity 2.

[0064] In a preferred embodiment of the present invention, the tablet press further comprises a lifting assembly 9 for driving the storage box 3 to lift and lower in the vertical direction, the lifting assembly 9 comprising: a base 901, a screw rod 902 and a slider 903; wherein,

A screw rod 902 is vertically and rotatably provided in each of the bases 901, and a slider 903 is threadedly fixed on each of the screw rods 902. Each of the sliders 903 partially extends from the window 11 and is fixed on the storage box 3.

[0066] In the above scheme, when in use, by rotating the two screw rods 902, with the cooperation of the window 11 of the base 901, in the process of rotating the two screw rods 902, it can be ensured that the two sliders 903 can smoothly and reliably drive the storage box 3 to rise and fall in the vertical direction along the axis of their respective corresponding screw rods 902.

[0067] In a preferred embodiment of the present invention, the lifting assembly 9 includes: a lifting motor 904; wherein,

[0068] A lifting motor 904 is vertically fixed on the top of each base 901, and the output shaft of each lifting motor 904 is coaxially connected to the screw rod 902 through a coupling.

[0069] In the above scheme, when in use, the lifting motor 904 is started by a worker to drive the screw rod 902 to rotate, and then drive the slider 903 to move up and down along its axis, and the two sliders 903 drive the storage box 3 to move up and down synchronously in the vertical direction during the synchronous lifting process.

[0070] In summary, the tablet press provided by the present invention overcomes the problem in the prior art that manual loading and unloading is required, which reduces work efficiency. In addition, the manual loading process will cause raw materials to scatter on the surface of the mold, which not only causes waste of raw materials but also requires staff to clean up, which is time-consuming and labor-intensive.
