Description

Technical Field

[0001] This utility model belongs to the field of packaging equipment technology, and more specifically, it relates to a supply metering device for a pill packaging machine. Background Technology

[0002] After production, the pills need to be packaged using a pill packaging machine. During the feeding stage of the pill packaging machine, a vibrating feeding plate is used for feeding. After the vibrating plate arranges the pills into a single row, the number of pills discharged is counted by the light screen of the electronic counter. The existing pill packaging machine's supply metering device generally consists of a vibrating feeding plate and a counting controller.

[0003] Existing application number: CN202223104511.7, this utility model discloses a vibratory feeder with counting function, relating to the field of vibratory feeder technology. It addresses the problem that existing vibratory feeders do not perform counting on the quantity conveyed, and most counts are performed uniformly after conveying, leading to complex counting. The vibratory feeder body has a discharge pipe at one end; it also includes: a counting cover plate, which is disposed at the upper end of the vibratory feeder body, and a digital display component is disposed at the upper end of the counting cover plate; infrared sensors, which are disposed at the lower end of the counting cover plate, and two infrared sensors are provided; a first mounting groove is provided on the lower surface of the counting cover plate, and a second mounting groove is provided on one side of the first mounting groove, and the first and second mounting grooves are integrally formed with the counting cover plate.

[0004] Based on the above, electronic counters are usually arranged in the linear discharge track area of ​​the vibrating feeder. However, due to the fixed tilt angle of the linear discharge track, they are not suitable for pills with high viscosity, irregular shape, or different surface characteristics: sticky pills often get stuck due to insufficient track tilt angle, which significantly reduces the conveying efficiency; while smooth pills may slide too fast due to excessive tilt angle, which in turn causes deviation in counting accuracy. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a metering device for a pill packaging machine. This addresses the issue that existing electronic counters are typically located in the linear discharge track area of ​​a vibrating feeding tray. However, due to the fixed inclination angle of the linear discharge track, they are not well-suited for pills with high viscosity, irregular shapes, or varying surface characteristics. Sticky pills often become stuck due to insufficient track inclination angle, significantly reducing conveying efficiency; while smooth-surfaced pills may experience excessive sliding speed due to excessive inclination angle, leading to deviations in counting accuracy.

[0006] The purpose and function of the metering device for a pill packaging machine of this utility model are achieved by the following specific technical means: A feeding and metering device for a pill packaging machine includes a mounting plate, a vibratory feeder body, a fixed discharge track, a counting controller, a connecting cable, a counting sensor, a swinging discharge track, a transmission box, an angle adjustment component, and a gap compensation component.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] Example 1: As shown in the attached document Figure 1 To be continued Figure 5 As shown: This utility model provides a feeding and metering device for a pill packaging machine, including a mounting plate 1, a vibratory feeder body 2, a fixed discharge track 201, a counting controller 3, a connecting cable 4, a counting sensor 401, a swinging discharge track 5, a transmission box 6, and an angle adjustment component. The vibratory feeder body 2 is fixedly connected to the mounting plate 1; the fixed discharge track 201 is fixedly connected to the top of the vibratory feeder body 2; the counting controller 3 is fixedly connected to the mounting plate 1; the connecting cable 4 is fixedly connected to the rear of the counting controller 3; the counting sensor 401 is fixedly connected to the rear end of the connecting cable 4; the swinging discharge track 5 is located on the right side of the fixed discharge track 201; the transmission box 6 is fixedly connected to the rear of the fixed discharge track 201; and the angle adjustment component is located at the right end of the fixed discharge track 201.

[0025] The angle adjustment assembly also includes: a first connecting block 8, a connecting shaft 9, and a transmission worm gear 901; two first connecting blocks 8 are provided, and the left ends of the two first connecting blocks 8 are respectively fixedly connected to the bottom of the fixed discharge track 201; the connecting shaft 9 is rotatably connected to the inside of the right end of the first connecting block 8; the transmission worm gear 901 is coaxially fixedly connected to the rear end of the connecting shaft 9, and the transmission worm gear 901 meshes with the transmission worm 701.

[0026] The angle adjustment component also includes: a second connecting block 10 and a following connecting block 11; the left end of the second connecting block 10 is fixedly connected to the outside of the connecting shaft 9, and the right end of the second connecting block 10 is fixedly connected to the bottom of the swing discharge track 5; the following connecting block 11 is fixedly connected to the top of the swing discharge track 5, and the following connecting block 11 is fixedly connected to the counting sensor 401.

[0027] The specific usage and function of this embodiment are as follows: When using the pills, if the pills are highly viscous or irregularly shaped, it is necessary to increase the tilt angle of the oscillating discharge track 5 to speed up the conveying. At this time, the top of the operating lever 7 can be rotated, and the worm gear transmission mechanism formed by the meshing of the transmission worm wheel 901 and the transmission worm 701 will drive the second connecting block 10 and the oscillating discharge track 5 to swing, thereby causing the right end of the oscillating discharge track 5 to tilt downward. During the process, the following connecting block 11 drives the counting sensor 401 to move synchronously, ensuring that the position of the counting sensor 401 is synchronized with the oscillating discharge track 5, thus ensuring the accuracy of the counting. The length of the connecting cable 4 is designed to have a certain redundancy to avoid dragging damage to the connecting cable 4 when the counting sensor 401 moves.

[0028] Example 2: Based on Example 1, as shown in the appendix Figure 1 To be continued Figure 5 As shown, it also includes a gap compensation component, which is installed inside the fixed discharge track 201.

[0029] The gap compensation component includes a winding shaft 12 and a winding belt 1201. The winding shaft 12 is rotatably connected to the inside of the right end of the fixed discharge track 201.

[0032] The specific usage and function of this embodiment are as follows: When the right end of the swing discharge track 5 tilts downward, it will cause the winding belt 1201 to be pulled out from the inside of the right end of the fixed discharge track 201. The side baffle 13 swings with the swing discharge track 5, which can protect both sides, thereby providing a passage for the pills. Even if some small gaps are generated after the side baffle 13 swings, it will not affect the passage of the pills. When the winding belt 1201 is pulled out, the winding shaft 12 will be driven to rotate, thereby driving the reset shaft 1202 to rotate synchronously, and the spiral spring 1203 will tighten. When the swing discharge track 5 is adjusted back to its original position, the spiral spring 1203 will release and rebound, causing the excess part of the winding belt 1201 to be retracted into the inside of the right end of the fixed discharge track 201, which will not affect the passage of subsequent pills.
