Description

Technical Field

[0001] This utility model relates to the field of pellet dispensing equipment technology, specifically a metering plate mold that can quickly adjust the quantity of pellets. Background Technology

[0002] Solid pill preparation workshops typically use packaging machines for pill packaging. The main steps of pill packaging are as follows: The product first enters a multi-row packaging machine through a feeding system, where it is conveyed to the machine's inlet. The multi-row packaging machine divides the incoming product into multiple rows according to set packaging specifications, usually arranged one row at a time. Next, the sorted products enter the packaging system. In the packaging system, different packaging methods are used based on the product's specific packaging requirements, such as bagging, bottle packaging, and boxing. The multi-row packaging machine usually automatically completes bag forming, filling, sealing, and coding processes during the packaging process. The entire packaging process is intelligently managed by a control system. The control system uses a PLC (Programmable Logic Controller) to guide the operation of the multi-row packaging machine according to preset programs and parameters. Operators can set packaging specifications, adjust production parameters, and monitor the machine's operating status in real time through a human-machine interface. The packaged products finally exit from the multi-row packaging machine's outlet and enter the next stage of the production process, such as subsequent packaging, boxing, or warehousing.

[0003] Normally, after the pellets are put into the hopper, the servo motor rotates the metering disc to accurately distribute the pellets into the metering plate mold holes. The pellets are held by the ejector pins in the metering plate holes (one pellet per hole), and excess pellets are brushed off by the brush above the metering plate. Then, the pellets in the metering plate mold holes are conveyed by the servo motor, and then the cylinder controls the ejector pins to push out the pellets in each hole into the feeding tube; thus, they enter the composite film to complete the packaging.

[0004] Currently, metering plate molds of the same specifications are available in 8-hole and 9-hole versions. When changing packaging specifications for the same product (e.g., changing from 9-piece packaging to 8-piece packaging), all 15 components of the 9-piece mold and the hopper must be removed, and then the 8-piece mold and hopper must be reinstalled. This replacement method has many drawbacks. First, the entire process is time-consuming and labor-intensive, requiring operators to spend a significant amount of time and energy on disassembly and installation. Second, the lengthy replacement process causes the equipment to be unable to operate normally for an extended period. Third, errors and mold damage may occur during installation. All of these factors reduce equipment utilization, affect production efficiency, and increase production costs. Utility Model Content

[0005] This invention overcomes the shortcomings of the prior art by proposing a metering plate mold that can quickly adjust the quantity of pills, thus solving the problems of time-consuming and labor-intensive mold replacement and reduced equipment utilization in the prior art.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: A metering plate mold for quickly adjusting the quantity of pills includes a base plate, a top cover plate, and several ejector pins; it also includes a lead screw and a plug. The top cover plate is located above the base plate and is fixedly connected to the base plate, with a gap between them. The top cover plate has multiple sets of through holes. Each through hole extends from the top to the bottom of the top cover plate, and an ejector pin is installed in each through hole. The bottom of the ejector pin passes through the through hole and is detachably connected to the base plate. The top of the ejector pin is lower than the top of the through hole. The plug is connected to the top of the lead screw, and the bottom of the lead screw is used to penetrate into the through hole to be closed and connect to the base plate. The upper surface of the plug is flush with the top surface of the closed through hole.

[0007] Furthermore, the top cover plate and the bottom plate are fixedly connected by bolts.

[0008] Furthermore, the top cover plate and the bottom plate are parallel to each other.

[0009] Furthermore, the upper cover plate is provided with multiple sets of through holes arranged in an array.

[0010] Furthermore, the bottom of the ejector pin is provided with an external thread, and the base plate is provided with threaded holes that correspond one-to-one with the through holes, and the bottom of the ejector pin is threadedly connected to the threaded holes.

[0011] Furthermore, the bottom of the lead screw is inserted into a closed through hole and connected to a corresponding threaded hole.

[0012] Furthermore, the lead screw is made of stainless steel.

[0013] The beneficial effects of this utility model compared to the prior art are as follows: With the mold described in this utility model, when it is necessary to change the mold, for example, from a 9-piece mold to an 8-piece mold, it is no longer necessary to dismantle the entire 15 parts and material hopper of the 9-piece mold. Only the nuts on the stainless steel threaded rod need to be removed or installed to achieve the effect of an 8-piece mold, without causing any discrepancies in packaging specifications. This utility model can achieve the effect of quick and convenient mold replacement, effectively solving the problems of time-consuming and labor-intensive mold replacement and reduced equipment utilization in the prior art.

[0016] See Figures 4 to 5 This embodiment proposes a metering plate mold that can quickly adjust the number of pills. This embodiment takes changing from a 9-pill mold to an 8-pill mold as an example. The metering plate mold is installed on a pill packaging machine, which is an existing device. Figures 1 to 3 The metering plate mold includes a base plate 1, an upper cover plate 2, several ejector pins 3, a lead screw 4, and a plug 5. The upper cover plate 2 is located above the base plate 1 and is fixedly connected to the base plate 1 by bolts. A gap is left between the upper cover plate 2 and the base plate 1, and the two are parallel. The upper cover plate 2 has multiple sets of through holes 6 arranged in an array, with 9 through holes 6 in each set. The 9 through holes 6 are arranged in a 3×3 structure. The through holes 6 extend from the top to the bottom of the upper cover plate 2. An ejector pin 3 is installed in each through hole 6.
