Description

Technical Field

[0001] The utility model relates to a micro-pill feeding control device for a capsule machine. Background Art

[0002] When the existing fully automatic intermittent hard capsule filling machine is filling micro-pills, the pre-filled micro-pills are added to the feeding bin and then passed through the vertical feeding tube to the pill hopper by gravity. The metering needle enters the pill hopper vertically, vacuum adsorption extracts the pills, and the two-way vertical and rotational motion completes the material collection and filling steps. Its disadvantages are: when it is found in the continuous commercial production process, due to the different process routes of different products, the size, static electricity and fluidity of the micro-pills are different, resulting in the following defects in the micro-pill feeding process: Problem 1: Micro-pills with poor fluidity will be mixed with auxiliary materials such as silicon dioxide that have a flow-aiding effect. During the feeding process, due to the influence of static electricity, the auxiliary materials will be adsorbed and accumulated on the inner wall of the feeding tube, resulting in blockage of the micro-pill feeding and affecting the product quality; Problem 2: For products with more fine powder auxiliary materials, vacuum adsorption and extraction of pills during long-term canning will suck a large amount of fine powder auxiliary materials into the vacuum pump filter element, blocking the filter element, resulting in insufficient vacuum suction during the canning process, and ultimately causing problems such as unstable capsule filling and abnormal capsule separation. Question 3: Since the volume and density of micro-pellets are larger than those of fine powder excipients, the fine powder excipients will settle to the bottom of the feeding bin under the influence of gravity and static electricity, resulting in an uneven ratio of pellets and fine powder excipients during the micro-pellet feeding process, causing large fluctuations in the capsule filling amount. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a micro-pill feeding control device for a capsule machine, which is used to solve the problem that auxiliary materials will be adsorbed and accumulated in a feeding pipe, resulting in blockage of the feeding pipe and the filter element of a vacuum pump, and the ratio of pills to fine powder auxiliary materials is uneven, thus affecting product quality.

[0004] In order to solve the above problems, the technical solution of the utility model is:

[0005] The micro-pill feeding control device of the capsule machine comprises a feeding bin, a discharge port at the bottom of the feeding bin, and an insertion tube. A circle of limiting ridges is arranged outside the insertion tube. The ridges divide the insertion tube into an upper part and a lower part. The lower part can be detachably inserted into the discharge port.

[0006] It also includes a filter plate, a through hole is opened in the center of the filter plate, the upper part passes through the through hole, and the edge of the filter plate is against the inner wall of the lower silo.

[0007] The beneficial effects of the utility model are as follows: it can meet the switching of feeding requirements between micro-pellets of different processes; when used in the feeding process of micro-pellets containing fine powder auxiliary materials, it can ensure smooth feeding while avoiding quality problems such as clogging of the feeding pipe due to fine powder and fluctuation of loading amount; in the feeding process of micro-pellet products without fine powder auxiliary materials, it is simple to remove the control device and easy to replace. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] The utility model is further described below in conjunction with the accompanying drawings:

[0010] Figure 2 It is a three-dimensional structural schematic diagram of the utility model.

[0011] Figure 3 It is a schematic diagram of the main structure of the utility model.

[0012] In the figure: filter plate 1, lower bin 2, upper part 3, lower part 4, limiting ridge 5. DETAILED DESCRIPTION

[0013] like Figure 1 and 2 As shown, the capsule machine pellet feeding control device includes a feeding bin 2, a discharge port at the bottom of the feeding bin 2, and an insertion tube. A circle of limiting ridges 5 are provided outside the insertion tube. The ridges 5 divide the insertion tube into an upper part 3 and a lower part 4. The lower part 4 can be detachably inserted into the discharge port.

[0014] Before canning pellets with more fine powder, insert and nest the cannula on the bottom discharge port of the lower silo 2. When the canning production starts and the pellets are added to the lower silo 2, the fine powder settles at the bottom of the lower silo 2 due to the influence of equipment vibration and electrostatic adsorption. Since the upper part 3 of the cannula is higher than the discharge port, the settled fine powder can be effectively blocked outside the feed port, and the pellets in the upper part 3 of the lower silo 2 can smoothly enter the discharge pipe, and the discharge is completed smoothly without fine powder mixed in the pellets causing blockage of the discharge pipe. The reduction of fine powder in the discharged pellets also solves the problem of vacuum pump filter blockage and loading fluctuation.

[0015] It also includes a filter plate 1, the center of which is provided with a through hole, the upper portion 3 passes through the through hole, and the edge of the filter plate 1 is against the inner wall of the lower bin 2. The fine powder is filtered through the filter plate 1 to increase the amount of fine powder falling. In addition, after the current batch of micro-pellet products is completed, the cannula and the filter screen are pulled out, and the remaining fine powder and micro-pellets are discharged as waste.

[0016] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limitations of the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
