[0025] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0026] This application discloses a rotary tablet press for producing compressed candy. (See also...) Figure 1-6 A rotary tablet press for producing compressed candy includes a base frame 1, a machine frame 2, a tablet pressing assembly, a quantitative filling mechanism, a dust collection assembly, and a drive mechanism.

[0027] The base frame 1 provides stable support for the entire equipment. Its top outer wall is fixedly connected to the machine frame 2 by welding or bolts. The tablet pressing assembly includes a rotating shaft 3 rotatably connected to the inner wall of the bottom of the machine frame 2. The rotating shaft 3 can rotate flexibly through bearings. The outer circumference of the rotating shaft 3 is sequentially fixedly mounted from top to bottom by key connection or welding to the tablet pressing plate 6, the mounting plate 5 and the base 4. The three rotate synchronously with the rotating shaft 3.

[0028] The quantitative filling mechanism is used to precisely control the material filling amount. It includes a fixed frame 16, a conveying box 17, a screw conveyor 18, a first motor 19, a distribution box 21, a star-shaped distribution plate 22, a second motor 23, a feeding hopper 24, a conveying pipe 20, and a filling head 31. Specifically, the fixed frame 16 is welded to the outer wall of the base frame 1 to provide support for the conveying box 17; the screw conveyor 18 is rotatably connected to the inner wall of the conveying box 17 via bearings; the first motor 19 is fixedly installed on the outer wall of one end of the conveying box 17, and its output shaft is fixedly connected to one end of the screw conveyor 18. The first motor 19 drives the screw conveyor 18 to rotate, realizing the horizontal conveying of materials; the distribution box 21, which is connected to the top outer wall of the conveying box 17, is rotatably connected to the star-shaped distribution plate 22 via bearings; the second motor 23 is fixedly installed on the inner wall of the distribution box 21. Installed on the outer wall of the distribution box 21, its output shaft is fixedly connected to the axis of the star-shaped distribution plate 22. The second motor 23 drives the star-shaped distribution plate 22 to evenly distribute the material. The top of the distribution box 21 is fixedly connected to the feeding hopper 24, which is used to add material. The bottom outer wall of the conveying box 17 is provided with a conveying pipe 20. One end of the conveying pipe 20 is connected to the conveying box 17, and the other end extends into the machine frame 2 and is fixedly connected to the filling head 31. The filling head 31 fits tightly against the top outer wall of the mounting plate 5 to ensure that the material is accurately filled into the mold 13 on the mounting plate 5.

[0029] Multiple guide holes are provided on the outer wall of the tablet pressing disc 6. Multiple pressure columns 10 are slidably connected to the tablet pressing disc 6 through the guide holes. Two return springs 12 are respectively installed between the pressure columns 10 and the tablet pressing disc 6. The top end of the return spring 12 is welded to the outer wall of the pressure column 10, and the bottom end is welded to the top outer wall of the tablet pressing disc 6 to provide return elastic force for the pressure column 10. The top end of the pressure column 10 is rotatably connected to the second pulley 11. The inner wall of the machine frame 2 is fixed by welding a fixing rod 14, and the outer wall of the fixing rod 14 is fixedly connected to the extrusion wheel 15.

[0030] Multiple guide grooves are provided on the outer wall of the chassis 4. Multiple top columns 7 are slidably connected to the chassis 4 through the guide grooves. The bottom end of the top column 7 is rotatably connected to the first pulley 9. The bottom inner wall of the frame 2 is fixedly connected to the first arc-shaped boss 8. When the rotating shaft 3 drives the pressing plate 6, the mounting plate 5 and the chassis 4 to rotate synchronously, the second pulley 11 contacts the extrusion wheel 15. The extrusion wheel 15 forces the pressing column 10 to move downward. At the same time, the first pulley 9 contacts the first arc-shaped boss 8. The first arc-shaped boss 8 pushes the top column 7 to move upward. At this time, the bottom end of the pressing column 10 and the top end of the top column 7 are inserted into the mold 13 embedded in the inner wall of the mounting plate 5. The pressing column 10 presses the material in the mold 13, and the top column 7 provides support at the bottom to ensure that the pressing process is stable and the material is subjected to uniform force.

[0031] After pressing is completed, as the equipment continues to rotate, the pressure column 10 leaves the extrusion wheel 15 and returns to its original position under the action of the return spring 12; the top column 7 leaves the first arc-shaped boss 8 and slides down along the guide groove to return to its original position, preparing for the next pressing cycle. Multiple molds 13 are embedded in the inner wall of the mounting plate 5. The matching plug-in structure of the pressure column 10 and the top column 7 effectively ensures the continuity and reliability of the pressing and demolding actions.

[0032] The outer wall of the frame 2 is provided with a discharge port 33. One end of the discharge port 33 inside the frame 2 corresponds to a mold 13. The bottom inner wall of the frame 2 is fixedly connected to a second arc-shaped boss 32, which is correspondingly set with the discharge port 33. When the pressed candy piece is rotated to the position of the discharge port 33 by the mounting plate 5, the top column 7 moves upward again under the action of the first arc-shaped boss 8, pushing the candy piece out of the mold 13. Under the guidance of the second arc-shaped boss 32, the candy piece is discharged from the discharge port 33. It is worth noting that the height of the first arc-shaped boss 8 is less than that of the second arc-shaped boss 32, ensuring that the first arc-shaped boss 8 will not cause the top column 7 to rise excessively and abut against the pressure column 10, causing interference. The second arc-shaped boss 32 ensures that the top column 7 can rise to a sufficient height, so that the pressed candy piece can be removed from the inside of the mold 13.

[0033] The dust collection assembly includes a suction head 29 and a vacuum cleaner 30. The suction head 29 is located inside the frame 2, between the first arc-shaped boss 8 and the extrusion roller 15. The vacuum cleaner 30 is installed on the outer wall of the base frame 1, and its suction end is connected to the suction head 29 through a suction pipe to remove the dust generated during the tablet pressing process.

[0034] The drive mechanism includes a third motor 27, a drive wheel 28, a driven wheel 25, and a synchronous belt 26. The third motor 27 is fixedly installed on the inner wall of the base frame 1, and its output shaft is fixedly connected to the drive wheel 28. The bottom end of the rotating shaft 3 passes through the machine frame 2 and is fixedly connected to the driven wheel 25. The driven wheel 25 and the outer wall of the drive wheel 28 are driven by the synchronous belt 26. The entire tablet press is driven by the third motor 27.

[0035] The implementation principle of a rotary tablet press for producing compressed candy according to an embodiment of this application is as follows: The third motor 27 is started, driving the rotating shaft 3 to rotate via the synchronous belt 26, causing the tableting disc 6, mounting disc 5, and base 4 to rotate synchronously. Material is added to the feeding hopper 24, and the second motor 23 drives the star-shaped distribution disc 22 to evenly distribute the material to the conveying box 17. The first motor 19 drives the spiral conveying rod 18 to convey the material to the filling head 31, achieving quantitative filling. During the rotation of the tableting disc 6, the extrusion wheel 15 cooperates with the first arc-shaped boss 8, driving the pressure column 10 and the top column 7 to move synchronously to complete the material compression. The compressed candy tablets are discharged from the discharge port 33 under the action of the top column 7 and the second arc-shaped boss 32. Simultaneously, the vacuum cleaner 30 removes the dust generated during the tableting process through the suction head 29, ensuring a clean production environment.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
