Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a tablet counting device. Background Technology

[0002] In the fields of pharmaceuticals, food, and health products, tablet counting devices are the core equipment for achieving quantitative dispensing of tablet products (such as pills, health supplement tablets, effervescent tablets, etc.) during the production and packaging process. Their main function is to accurately count a batch of tablets and then transport them to packaging containers such as bottles and bags as needed, directly affecting product packaging efficiency, counting accuracy, and production continuity.

[0003] Currently, tablet counting devices on the market typically consist of core components such as a hopper, a feeding channel, counting components (e.g., photoelectric sensors, capacitive counters), a vibrating feeding mechanism, and a discharging mechanism. Their working principle is roughly as follows: a batch of tablets stored in the hopper is conveyed to the counting component by gravity along the feeding channel. After the counting component identifies and counts the tablets, those meeting the set quantity are dispensed through the discharging mechanism. However, with the pharmaceutical industry's increasing demands for production automation, packaging precision, and efficiency, existing tablet counting devices have gradually revealed key technical deficiencies in practical applications. Among these, tablet clogging is particularly prominent and has become a core bottleneck restricting their reliability and applicability.

[0004] Therefore, it is necessary to provide a new tablet counting device to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a tablet counting device.

[0006] This utility model provides a tablet counting device, including a counting shell, a counting turntable, four spring sleeves, and four support columns. The counting shell has a counting cavity inside, and a feeding port is opened at the eccentric top of the counting shell. The counting cavity is connected to the feeding port. A feeding guide frame plate is fixedly connected to the inner wall of the counting cavity away from the feeding port. A stirring and feeding component is provided inside the feeding guide frame plate. The counting turntable is rotatably connected between the counting cavity and the feeding guide frame plate. The counting turntable has multiple tablet counting holes arranged in an orderly manner. The counting shell is provided with a drive component that drives the counting turntable to rotate. Four spring sleeves are fixedly connected to the lower edge of the counting shell. A buffer component is provided between the four spring sleeves and the four support columns.

[0007] Preferably, the drive assembly includes a servo motor and a motor shaft. The servo motor is fixedly connected to the center of the top of the counting housing. The output end of the servo motor is connected to one end of the motor shaft, and the other end of the motor shaft passes through the inside of the counting housing and is fixedly connected to the upper surface of the counting turntable.

[0008] Preferably, the mixing and feeding assembly includes a mixing motor, a mixing motor shaft, and multiple mixing rods. The mixing motor is located on one side of the outer wall of the feeding guide frame plate, and the mixing motor shaft is rotatably connected between the inner walls of both sides of the feeding guide frame plate. The output end of the mixing motor is connected to one end of the mixing motor shaft, and multiple mixing rods are provided on the outer surface of the mixing motor shaft.

[0009] Preferably, the buffer assembly includes a spring groove 1, a buffer rod and a buffer spring. The bottom center of the four spring sleeves is provided with a spring groove 1, the top center of the support column is provided with a spring groove 2 and a buffer rod groove, a buffer spring is provided between the spring groove 1 and the spring groove 2, one end of the buffer rod is fixedly connected to the inner top wall of the spring groove 1, and the other end of the buffer rod passes through the support column and the spring groove 2 to the inside of the buffer rod groove.

[0010] Preferably, the bottom of the counting housing is fixedly connected to the discharge channel, and two vibration motors are provided on the lower surface of the discharge channel.

[0011] Preferably, a feeding channel is fixedly connected to the eccentric part of the top of the counting housing, the feeding channel is connected to the counting chamber, and the feeding channel is set perpendicular to the position of the feeding guide frame plate.

[0012] Compared with related technologies, the tablet counting device provided by this utility model has the following beneficial effects: The mixing and feeding assembly drives multiple mixing rods to rotate. As the mixing rods rotate, they directly break up the bridging structure formed by the electrostatic adsorption and stacking of tablets in the hopper, preventing tablets from getting stuck at the hopper outlet. This ensures that tablets fall continuously and evenly into the feeding channel, eliminating the need for manual cleaning of the bridging and reducing equipment downtime caused by feeding interruptions. At the same time, the vibration motor causes the device to shake slightly, which can dislodge tablets attached to the corners of the inner wall of the feeding guide plate and the gaps between the mixing rods, avoiding material waste caused by tablet adsorption residue. Combined with the mixing of the mixing rods, this achieves tablet feeding without dead corners in the hopper, improving material utilization. Attached Figure Description
