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] It should be noted that this embodiment provides one device, and in practice, 3 to 5 devices may be provided, each of which can reciprocate independently.

[0026] Example 1, please refer to Figures 1 to 7 This embodiment provides a single-module follower device, including a main body 1 of the device. Figure 1 As shown, a counting box 2 is fixedly connected to the end face of the main body 1. The main body 1 and the counting box 2 refer to a tablet counting machine of model DS-8. The main body 1 stores tablets inside, and the counting box 2 counts tablets through a single-tablet output port.

[0027] The lower end of the counting box 2 is provided with a discharge port. After the number of tablets is confirmed to be in the counting box 2, the tablets can be discharged through the discharge port after the discharge port is opened. When bottling, the conveyor is stopped, that is, the movement of the medicine bottle is stopped, and the bottle mouth of the medicine bottle is aligned with the discharge port up and down. At this time, the tablets discharged from the discharge port can fall into the medicine bottle by their own gravity for filling. In order to increase the bottling efficiency, multiple counting machines can be set up to work side by side.

[0028] A long-term stop of the conveyor will accelerate the aging of the components in the conveyor, damage the components of the conveyor, and affect the tablet bottling efficiency. In order to prevent the conveyor from stopping, a counting machine feed head 3 is slidably installed on the outer side wall of the main body 1.

[0029] Specifically, the outer wall of the counting machine blanking head 3 is fixedly connected with a sliding plate 4, the outer wall of the main body 1 is provided with a slide rail, and the sliding plate 4 is slidably installed in the slide rail. The sliding of the sliding plate 4 can drive the counting machine blanking head 3 to slide at the end surface of the main body 1.

[0030] like Figure 2As shown, the main body 1 is provided with a reciprocating mechanism 5, through which the slide can be driven to move back and forth in the slide rail. Specifically, the reciprocating mechanism 5 includes a sprocket 51, a chain 52 and a shifting block 53. Figure 4 As shown, two sprockets 51 are provided, and both sprockets 51 are rotatably mounted inside the main body 1, and the two sprockets 51 are located in the same horizontal plane. The chain 52 is sleeved on the outer side walls of the two sprockets 51, and the chain 52 and the sprockets 51 are meshed with each other, and the two sprockets 51 tighten the chain 52. A motor is fixedly installed inside the main body 1, and the output shaft of the motor is fixedly connected to one sprocket 51. By starting the motor, the connected sprocket 51 can be driven to rotate, and the other sprocket 51 can be driven to rotate through the chain 52.

[0031] like Figure 5 As shown, the shift block 53 is provided with two, such as Figure 6 As shown, the shifting block 53 is rotatably mounted on the outer side wall of the chain 52 , and the two shifting blocks 53 are centrally symmetrically arranged with the center point of the two sprocket wheels 51 as the center of the circle.

[0032] The first spring 54 is installed in the track groove of the main body 1, that is, one end of the first spring 54 is fixedly connected to the side wall of one end of the track groove, and the other end is fixedly connected to the sliding plate 4. The first spring 54 applies elastic force to the sliding plate 4, so that the sliding plate 4 slides to the other end of the track groove, that is, the blanking head 3 of the counting machine moves to one side of the end face of the main body 1.

[0033] like Figure 5 As shown, a sliding groove is provided at one end of the sliding plate 4 facing the chain 52, a protrusion 41 is slidably inserted in the sliding groove, one end of the protrusion 41 is set as an inclined surface, and a first spring 54 is installed in the sliding groove, wherein one end of the first spring 54 is fixedly connected to the bottom of the sliding groove, and the other end is fixedly connected to one end of the protrusion 41, and the first spring 54 applies an elastic force to the protrusion 41 toward the groove of the sliding groove, so that the inclined surface end of the protrusion 41 extends from the side wall of the sliding plate 4.

[0034] like Figure 4 and Figure 5 As shown, a stopper 43 is fixedly installed inside the main body 1 . The stopper 43 is in a U-shaped structure, and one end of the stopper 43 facing the sliding plate 4 is also arranged as an inclined surface.

[0035] When in use, the motor is started to drive the sprocket 51 and the chain 52 to rotate. At this time, the side wall of the shifting block 53 fits the side wall of the protrusion 41, and the chain 52 rotates continuously. The shifting block 53 drives the protrusion 41 to move, that is, drives the sliding plate 4 to slide in the track groove of the main body 1, and the counting machine feed head 3 moves synchronously with the sliding of the sliding plate 4. The counting machine feed head 3 moves at the same speed as the medicine bottle. The tablets discharged from the discharge port of the counting box 2 fall into the counting machine feed head 3, and then leak out from the lower end of the counting machine feed head 3. The leaked tablets can fall into the medicine bottle by their own gravity.

[0036] like Figure 1 As shown, the first spring 54 is continuously compressed as the sliding plate 4 moves, and the tablet counting machine blanking head 3 moves from the left side of the end surface of the main body 1 to the right side, and the tablets in the tablet counting machine blanking head 3 are discharged.

[0037] When the blanking head 3 of the counting machine is about to move to the rightmost side of the end face of the main body 1, the inclined surface of the stopper 43 fits with the inclined surface of the protrusion 41, and the inclined surface of the stopper 43 applies a reverse force to the inclined surface of the protrusion 41, driving the protrusion 41 to shrink into the slide groove of the sliding plate 4, and at this time, the second spring 42 is also compressed synchronously. When the inclined edge of the protrusion 41 fits with the inclined edge of the stopper 43, the shifting block 53 is separated from the contact with the protrusion 41, and at this time, the sliding plate 4 is subjected to the elastic force of the first spring 54 and quickly resets to one end of the track groove of the main body 1, that is, the blanking head 3 of the counting machine is reset to the left side of the end face of the main body 1. The continuous rotation of the sprocket 51 and the chain 52 can drive the sliding plate 4 to slide back and forth in the track groove, that is, drive the blanking head 3 of the counting machine to move back and forth on the end face of the main body 1, and the reciprocating blanking head 3 of the counting machine continuously fills multiple medicine bottles.

[0038] like Figure 3 As shown, the upper end opening of the counting machine feeding head 3 is relatively large. During the left-right movement of the counting machine feeding head 3 , the lower end discharge port of the counting box 2 is always located at the upper end of the counting machine feeding head 3 .

[0039] The tablets leaking out from the lower end of the counting machine feeding head 3 will be affected by the environment (air flow and static electricity, etc.), flow rate (the amount of tablets falling) and the physical characteristics of the tablets (shape and weight, etc.). The tablets will deviate during the falling process and thus cannot fall accurately into the medicine bottle. In order to solve the problem that the tablets cannot fall accurately into the medicine bottle, the lower end of the counting machine feeding head 3 is connected with a funnel-shaped material nozzle 31.

[0040] like Figure 1 As shown, a rubber sleeve is provided between the funnel-shaped nozzle 31 and the feeding head 3 of the grain counting machine, and the gap between the funnel-shaped nozzle 31 and the feeding head 3 of the grain counting machine is filled by the rubber sleeve. The rubber sleeve is set to be a rubber material, and the friction coefficient between the funnel-shaped nozzle 31 and the feeding head 3 of the grain counting machine is increased by the rubber sleeve, so that the funnel-shaped nozzle 31 is firmly sleeved on the lower end of the feeding head 3 of the grain counting machine.

[0041] like Figure 3 As shown, the lower end of the counting machine feeding head 3 is extended from the funnel-shaped nozzle 31, and the lower end discharge hole of the funnel-shaped nozzle 31 is close to the bottle mouth of the medicine bottle. By shortening the distance between the discharge position and the medicine bottle, the offset position of the tablets is reduced, thereby preventing the tablets from failing to fall into the medicine bottle accurately during the discharge process.

[0042] Embodiment 2, in this embodiment, different from embodiment 1, the cylinder fixes the side of the counting box. Synchronous pulleys and synchronous belts are used, the funnel-shaped nozzle is fixed on the synchronous belt, the synchronous belt rotates left and right, the funnel-shaped nozzle moves left and right following the synchronous belt, and the lower mouth of the funnel-shaped nozzle is clamped by a hook. There is a groove on the nozzle, and the groove is clamped, and the cylinder drives it to move up and down.

[0043] Embodiment 3, in this embodiment, the linear reciprocating movement mechanism adopts an 8-shaped lead screw.

[0044] Embodiment 4: In this embodiment, the linear reciprocating mechanism adopts a crank connecting rod.

[0045] Embodiment 5: In this embodiment, the linear reciprocating mechanism adopts a cam mechanism.

[0046] Embodiment 6. In this embodiment, the linear reciprocating motion mechanism adopts an electric push rod.

[0047] Embodiment 7: In this embodiment, a slide rail and slide table pair are used to achieve reciprocating movement.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
