[0023] In the present invention, unless otherwise clearly specified and defined, the terms "set", "installed", "connected", "connected", "fixed", etc. should be understood in a broad sense. For example, it may be a fixed connection or a detachable connection; it may be a mechanical connection; it may be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] Such as Figure 1As shown in the figure, a reciprocating tablet uniform material distribution device includes a conveying frame 1. A conveyor belt 2 and a first driving mechanism for driving the conveyor belt to work intermittently are provided on the conveying frame. The conveyor belt includes an endless belt and drive shafts provided at both ends thereof. The first driving mechanism drives one of the drive shafts to rotate intermittently. Above the input end of the conveyor belt, there are a feeding mechanism and a second driving mechanism for driving the feeding mechanism to reciprocate in the width direction of the conveyor belt. The feeding mechanism includes a feeding tray 4 and a feeding pipe 5. The outlet of the feeding pipe is connected to the upper end of the feeding tray. The feeding tray is inclined, and a flared feeding port 401 is provided at the end with a lower height. The inlet of the feeding pipe is connected to the outlet of the tablet drying device. The tablets fall into the feeding tray through the feeding pipe and slide down to the conveyor belt through the feeding port. A turned-up flange 402 is provided on the outer periphery of the upper end surface of the feeding tray, which can prevent the tablets from rolling off from the side of the feeding tray. The feeding pipe is a flexible pipe and is connected to the end of the feeding tray away from the feeding port, which is convenient for the driving mechanism to drive it to reciprocate. Baffles 12 are provided on both sides of the conveyor belt. The baffles are provided on the conveying frame and can prevent the tablets from rolling off from the side when sliding down to the conveyor belt from the feeding tray.

[0025] Combined with Figure 1 and Figure 2 As shown in the figure, the second driving mechanism includes a cross beam 6 spanning above the conveying frame and an eccentric transmission mechanism provided on one side of the conveying frame. The eccentric transmission mechanism is installed on the conveying frame by an L-shaped fixing frame. The cross beam is arranged in the width direction of the conveyor belt. A transmission rod 7 is hinged at one end of the cross beam away from the eccentric transmission mechanism. The transmission rod is hinged to the eccentric transmission mechanism. Elastic members 8 are connected between both sides of the lower end of the cross beam and the conveying frame. In this embodiment, the elastic members are springs. The feeding tray is installed at the top of the cross beam. The eccentric transmission mechanism includes a second motor 9, a rotating disk 10, and an eccentric rod 11. The second motor is connected to the rotating disk. The eccentric rod is provided on one side of the rotating disk. In this embodiment, the central axis of the rotating disk is on the same horizontal plane as the cross beam. The second motor drives the rotating disk to rotate, and one end of the eccentric rod rotates with the rotating disk, so as to realize the reciprocating movement of the cross beam and the feeding tray in the width direction of the conveyor belt, and spread the tablets in the width direction of the conveyor belt. Then, the first motor drives the conveyor belt to convey the tablets for a certain distance and then stops working. The second driving mechanism continues to work, and so on, so as to ensure that the tablets are evenly dispersed on the conveyor belt, which is convenient for subsequent drug packaging and processing. The cross beam and the feeding tray also have a small amplitude of up and down swing under the action of the second motor, further improving the uniformity of its material distribution.

[0026] As Figure 1 、 Figure 3 and Figure 4As shown, the first driving mechanism includes a driving disc 14, a transmission gear 15, a shift lever 16, a lever 17 and a first motor. The first motor is connected to the driving disc. One side of the circumferential surface of the driving disc is a smooth surface 1401, and the other side is provided with a driving tooth 1402, that is, the driving disc is an incomplete gear structure. The transmission gear is located on one side of the driving disc and meshes with the driving tooth for transmission. A notch 1501 is provided on one side of the driving gear, and a lever is provided at the notch. The lever cooperates with the shift lever provided on the driving disc, and the driving gear is connected to the transmission shaft at one end of the conveyor belt. First, the smooth surface of the driving disc fits the transmission gear, and the first motor drives the driving disc to rotate counterclockwise (based on Figure 3 The transmission gear is engaged with the driving tooth and continues to rotate. When the driving disc continues to rotate until the last tooth of the driving tooth reaches the upper side of the driving disc, the driving disc is disengaged from the driving tooth, and the transmission gear stops rotating at this time. When the gear lever on the driving disc rotates to the lever position again, it drives the transmission gear to rotate again, and so on, thereby realizing intermittent conveying of the conveyor belt.

[0027] The working principle of the utility model is as follows:

[0028] like Figure 1 and Figure 2 As shown, the dried tablet medicine is conveyed from the discharge pipe 5 to the discharge tray 4, and then slides from the discharge tray 4 to the conveyor belt 2. The second motor 9 drives the rotating disc 10 to rotate, driving the transmission rod 7 to swing back and forth, so that the crossbeam 6 and the discharge tray 4 swing back and forth along the width direction of 2. The first motor 3 drives the conveyor belt 2 to work intermittently. When the width direction of one position of the conveyor belt 2 (the first discharge area, and so on, the same below) is full of tablets, the conveyor belt 2 continues to convey, and the second discharge area of ​​the conveyor belt 2 reaches the bottom of the discharge tray. The discharge mechanism then fills the width direction of the second discharge area, and so on, thereby completing the reciprocating uniform distribution of tablets.

[0029] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model.
