DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] Based on the existing prior art, when tableting products such as royal jelly freeze-dried powder and royal embryo freeze-dried powder, the single pressing of the double-track double-outlet rotary tablet press will result in insufficient product pressure due to insufficient material viscosity, which is prone to problems such as loose tablets and top cracking. This embodiment provides a rotary tablet press for the production of royal jelly freeze-dried powder tablets, please refer to Figures 1-6, An embodiment provides a rotary tablet press for producing freeze-dried royal jelly tablets, which can apply secondary pressure to the freeze-dried royal jelly to make the tablets more stable and not easily cracked at the top. The pressure-forming device for the freeze-dried royal jelly tablets includes a pressure wheel box 2 installed on the upper part of the tablet press body 1 to drive the punch to move downward for tablet pressing. Inside the tablet press body 1, there is a tablet pressing mechanism 3 for punching the freeze-dried powder into tablets. The upper punch 3074 in the tablet pressing mechanism 3 is pressed down by the pressure wheel inside the pressure wheel box 2 and cooperates with the lower die 304 in the middle die hole 3072 to press the freeze-dried royal jelly into tablets. By changing the tablet outlet convex plate 305 on one side of the tray 301 to a protective plate 306, the freeze-dried powder inside the middle die hole 3072 can continue to be rotated and conveyed for secondary pressure forming into tablets, improving the stability of tablet formation and avoiding phenomena such as loose tablets and cracked tops.

[0027] Since in the prior art, when pressing and producing products such as freeze-dried royal jelly powder and freeze-dried queen bee larvae powder, the single-time pressure forming of the rotary tablet press with double tracks and double outlets will have problems such as insufficient product pressure and easy occurrence of loose tablets and cracked tops due to insufficient material viscosity. Therefore, a tablet pressing mechanism 3 that can apply secondary pressure to the freeze-dried powder to form tablets is proposed. The tablet pressing mechanism 3 includes a tray 301 installed inside the tablet press body 1. A rotating column 302 is rotatably connected to the tray 301. Upper and lower parts of the rotating column 302 are provided with turntables 303. A lower die 304 is slidably installed up and down inside the through holes opened on the turntables 303, and the bottom of the lower die 304 is in contact with the tray 301. A tablet outlet convex plate 305 is installed on the right side of the upper surface of the tray 301, and a protective plate 306 is installed on the left side of the upper surface of the tray 301. A tablet pressing component 307 for applying pressure to the freeze-dried powder to form tablets is provided on the rotating column 302. Quick-disassembly and assembly components 308 are installed at the bottoms of the tablet outlet convex plate 305 and the protective plate 306. By changing the tablet outlet convex plates 305 on both sides of the tray 301 to one tablet outlet convex plate 305 and one protective plate 306, when the lower die 304 rotates to the protective plate 306, the freeze-dried tablets pressed once will not be pushed up and discharged again, but will continue to rotate for secondary pressure, thereby making the tablets more stable and not easily cracked at the top.

[0028] The tablet pressing assembly 307 includes a stamping plate 3071 installed in the rotating column 302. A middle die hole 3072 is annularly and penetratingly formed in the stamping plate 3071. An upper punch plate 3073 is installed on the upper part of the rotating column 302. An upper punch 3074 is slidably connected up and down inside the through hole formed in the upper punch plate 3073. The lower die 304, the middle die hole 3072, and the upper punch 3074 are vertically corresponding. The rotating column 302 is driven to rotate by an external power source, thereby driving the turntable 303, the stamping plate 3071, and the upper punch plate 3073 thereon to rotate, and further driving the lower die 304 inside the turntable 303 and the upper punch 3074 inside the upper punch plate 3073 to rotate until the upper punch 3074 is pressed by the pressing wheel inside the pressing wheel box 2 and cooperates with the lower die 304 at the bottom to press the freeze-dried powder into tablets in the middle die hole 3072 on the stamping plate 3071.

[0029] A main control console 4 is installed on the tablet press body 1, and the tablet pressing mechanism 3 is electrically connected to the main control console 4.

[0030] Embodiment 2

[0031] On the basis of Embodiment 1, as Figures 1-6 shown, when installing the protection plate 306, bolt connection and other methods are often used. However, the internal space of the tablet press body 1 is limited, and it is not convenient to use tools such as screwdrivers for installation. Therefore, the device is also provided with an installation component 308. The installation component 308 includes an installation hole 3081 formed in the tray 301. Connecting rods 3082 are installed at the bottoms of the sheet discharging convex plate 305 and the protection plate 306, and the connecting rods 3082 are inserted into the installation hole 3081. An external thread is formed at the bottom of the connecting rod 3082, and a tightening nut 3083 is threadedly connected to the connecting rod 3082. A clamping component 309 for enhancing the connection stability is arranged on the connecting rod 3082. According to the placement position of the tablet press body 1, the sheet discharging convex plate 305 or the protection plate 306 can be inserted into the installation hole 3081 through the connecting rod 3082, and then the tightening nut 3083 is tightened to fix the sheet discharging convex plate 305 or the protection plate 306 on either side of the tray 301, facilitating the adjustment of the discharging position.

[0032] The clamping assembly 309 includes a chute 3091 formed in the connecting rod 3082, and a spring 3092 is installed on the top wall of the chute 3091. A rotating ring 3093 is rotatably connected to the tightening nut 3083. A movable seat 3094 is installed on the rotating ring 3093. A bent connecting arm 3095 is rotatably connected inside the movable seat 3094. The other end of the bent connecting arm 3095 is slidably connected to the chute 3091 and is connected to the spring 3092. When the connecting rod 3082 is inserted into the installation hole 3081, the insertion thrust pushes the bent connecting arm 3095 to bend and straighten and compresses the spring 3092 inside the chute 3091, so as to complete the insertion smoothly. Subsequently, the spring 3092 resets under its own elastic force, so as to reset the bent connecting arm 3095. At this time, the tightening nut 3083 is screwed to drive the whole bent connecting arm 3095 to move upward until it abuts against the bottom of the tray 301, so as to complete the stable and rapid connection of the protection plate 306, prevent the protection plate 306 from shaking, and facilitate subsequent disassembly and assembly.
