Description

Technical Field

[0001] This invention relates to the field of food and pharmaceutical packaging machinery technology, and in particular to a solid filling device. Background Technology

[0002] In recent years, various innovative drugs have emerged, some of which require the accurate counting of a certain number of micro-tablets (generally referring to tablets with a diameter × thickness of less than 3 × 3 mm) and filling them into capsules without damage. If the traditional method of filling large tablets, pushing the tablets into the capsule one by one, is used, the efficiency is too low and the speed cannot keep up. In addition, the parts for transferring micro-tablets need to be manufactured to be very small, requiring high processing precision, which leads to high equipment costs.

[0003] However, if traditional microcapsules (or micro-powders) are used for filling (treating microcapsules as microcapsules), problems such as poor flowability, material shortages, and low filling efficiency will be encountered. Microcapsule shortages will cause the fill volume difference to exceed the specified range, thus requiring a high-efficiency filling mechanism that can improve the flowability of microcapsules and accurately count the particles. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a solid filling device that is simple in structure, reliable, and conducive to improving fluidity and avoiding scratches.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A solid filling device includes a buffer bin, a feeding tray, a feeding pipe, and a feeding hopper connected in sequence. The feeding tray is located on the upper side of the mounting base and connected to a vibrator. The feeding hopper is located on the lower side of the mounting base and has a flexible layer on its outer wall. A metering plate is located on the lower side of the feeding hopper. The distance between the feeding hopper and the metering plate is greater than the thickness of the micro-sheets. The lower side of the flexible layer is located between the feeding hopper and the metering plate.

[0007] As a further improvement to the above technical solution: the distance between the flexible layer and the metering disk is 1 / 4 to 1 / 3 of the thickness of the micro-film.

[0008] As a further improvement to the above technical solution: the flexible layer is a silicone layer.

[0009] As a further improvement to the above technical solution: the mounting base is provided with a flexible support column, and the feed tray is located on the flexible support column.

[0010] As a further improvement to the above technical solution: the flexible support is a rubber support.

[0011] As a further improvement to the above technical solution: the metering disk is set on an intermittently rotating tower, and the metering disk is provided with metering holes for micro-chips to enter one by one. The depth of the metering holes is an integer multiple of the thickness of the micro-chips. A sliding plate is provided on the lower side of the metering disk, and a micro-chip transmission channel is provided on the sliding plate. A capsule mold for placing capsules is provided on the lower side of the sliding plate. When the metering holes rotate to above the capsule mold, they are aligned with the micro-chip transmission channel.

[0012] As a further improvement to the above technical solution: an acceleration mechanism is provided above the metering disc to drive the micro-pieces in the metering hole into the capsule.

[0013] As a further improvement to the above technical solution: the acceleration mechanism includes a lifting bracket located on the outer periphery of the feed tray and a push rod located on the lifting bracket.

[0014] As a further improvement to the above technical solution: the acceleration mechanism also includes a transmission scraper block located on the lower side of the mounting base, and the transmission scraper block is provided with a guide channel for the push rod to pass through.

[0015] As a further improvement to the above technical solution: the acceleration mechanism includes an acceleration chamber located on the lower side of the mounting base, and the acceleration chamber is connected to an inflation pipe.

[0016] Compared with the prior art, the advantages of the present invention are as follows: In the solid filling equipment disclosed in the present invention, solid drugs (including micro flakes, powders, etc.) are first conveyed to the buffer bin for buffering during operation, then transferred to the feed tray, and then transferred to the feed hopper through the feed pipe, and finally fall into the metering tray. The vibrator drives the feed tray, feed pipe and feed hopper to vibrate, which improves the fluidity of the solid drugs during the transfer process and speeds up the speed at which they fall into the metering tray, which is conducive to improving filling efficiency. The distance between the feed hopper and the metering tray is greater than the thickness of the micro flakes, so the lower side of the feed hopper will not contact the micro flakes on the surface of the metering tray, avoiding the problem of scratching the micro flakes. The flexible layer of the outer wall of the feed hopper extends to the bottom of the feed hopper, which can prevent the micro flakes on the metering tray from escaping during operation, while also preventing the micro flakes from being scratched. The structure is simple and reliable. Attached Figure Description

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Example 1

[0029] Figures 1 to 4 An embodiment of the solid filling equipment of the present invention is shown. This embodiment includes a buffer bin 1, a feeding tray 2, a feeding pipe 3, and a feeding hopper 4, which are sequentially connected. The feeding tray 2 is located on the upper side of the mounting base 5 and connected to a vibrator 21. The feeding hopper 4 is located on the lower side of the mounting base 5 and has a flexible layer 41 on its outer wall. A metering plate 7 is located on the lower side of the feeding hopper 4. The distance between the feeding hopper 4 and the metering plate 7 is greater than the thickness of the micro-sheets 10. The lower side of the flexible layer 41 is located between the feeding hopper 4 and the metering plate 7. Preferably, the feeding hoppers 4 are arranged in 3 to 5 groups and evenly distributed around the circumference of the feeding tray 2, allowing for synchronous feeding, which helps improve filling efficiency.

[0030] In this embodiment of the solid filling equipment, during operation, solid medicine (micro-flakes 10 in this embodiment, and powder in other embodiments) is first conveyed to the buffer bin 1 for buffering, then transferred to the feed tray 2, and then transferred to the feed hopper 4 through the feed pipe 3, and finally falls into the metering tray 7. The vibrator 21 drives the feed tray 2, feed pipe 3 and feed hopper 4 to vibrate, which improves the fluidity of the micro-flakes 10 during the transfer process and speeds up the speed at which they fall into the metering tray 7, thus improving filling efficiency. The distance between the feed hopper 4 and the metering tray 7 is greater than the thickness of the micro-flakes 10, so the lower side of the feed hopper 4 will not contact the surface of the metering tray 7 with the micro-flakes 10, avoiding the problem of scratching the micro-flakes 10. The flexible layer 41 of the outer wall of the feed hopper 4 extends to the bottom of the feed hopper 4, which can prevent the micro-flakes 10 on the metering tray 7 from escaping during operation, while also preventing the micro-flakes 10 from being scratched, and is conducive to transmitting vibration to the micro-flakes 10, so that the micro-flakes 10 are neatly stacked, reducing skewing. The structure is simple and reliable.

[0031] In a preferred embodiment, the distance between the flexible layer 41 and the metering disk 7 is 1 / 4 to 1 / 3 of the thickness of the micro-piece 10. When scraping away excess micro-piece 10, it ensures that the micro-piece 10 will not be damaged, and also ensures that the micro-piece 10 cannot escape when the metering disk 7 is in operation.

[0032] In a preferred embodiment, the flexible layer 41 is a silicone layer. The silicone layer has good flexibility and can ensure reliable installation on the feed hopper 4.

[0033] Furthermore, in this embodiment, the mounting base 5 is provided with a flexible support column 51, and the feed tray 2 is disposed on the flexible support column 51. The flexible support column 51 is beneficial for transmitting the vibration of the vibrator 21 and the feed tray 2 to the micro-plates 10, accelerating the flow of the micro-plates 10, and at the same time making the micro-plates 10 stacked neatly.

[0034] In a preferred embodiment, the flexible support 51 is a rubber support. The rubber support can provide good support for the entire assembly, including the feed tray 2 and the vibrator 21, while transmitting vibrations.

[0035] Furthermore, in this embodiment, the metering disk 7 is disposed on the intermittently rotating rotating tower 71. The metering disk 7 is provided with metering holes 72 for the micro-chips 10 to enter one by one. The depth of the metering holes 72 is an integer multiple of the thickness of the micro-chips 10. A sliding plate 6 is provided on the lower side of the metering disk 7. A micro-chip transmission channel 61 is provided on the sliding plate 6. A capsule mold 9 for placing capsules 20 is provided on the lower side of the sliding plate 6. When the metering holes 72 rotate to above the capsule mold 9, they are aligned with the micro-chip transmission channel 61. See details. Figure 4Since there is only one micro-piece 10 at the same cross-section or height position of the metering hole 72, and the depth of the metering hole 72 is an integer multiple of the thickness of the micro-piece 10, the number of micro-pieces 10 in the metering hole 72 can be precisely controlled. The structure is simple and effective. After the micro-pieces 10 in the feed hopper 4 enter the metering hole 72, the rotating tower 71 drives the metering disk 7 to rotate intermittently. During the repeated start and stop process, each micro-piece 10 can be kept in a horizontal state, so that the micro-pieces 10 are neatly stacked. When the metering hole 72 rotates to the top of the capsule mold 9, the micro-pieces 10 fall from the micro-piece transfer channel 61 on the slide plate 6 into the capsule 20 under the action of their own gravity, completing the filling process.

[0036] Furthermore, in this embodiment, an acceleration mechanism 8 is provided above the metering disc 7 to drive the micro-pieces 10 in the metering holes 72 into the capsule 20. When the equipment operates at a slow speed, the micro-pieces 10 in the metering holes 72 can all fall into the capsule 20 by their own gravity. However, when operating at high speed, most of the micro-pieces 10 have not yet fallen in time before the metering disc 7 has to start the next cycle of rotation. Therefore, it is necessary to set up the acceleration mechanism 8 to speed up the falling speed of the micro-pieces 10 in the metering holes 72 to adapt to the high-speed filling of the micro-pieces 10.

[0037] Furthermore, in this embodiment, the acceleration mechanism 8 includes a lifting bracket 81 disposed on the outer periphery of the feed tray 2 and a push rod 82 disposed on the lifting bracket 81. When the metering hole 72 is vertically aligned with the micro-chip transfer channel 61, the lifting bracket 81 drives the push rod 82 to descend, quickly pushing the micro-chip 10 in the metering hole 72 into the empty capsule 20, and then drives the push rod 82 to rise and exit from the metering hole 72. The structure is simple and effective.

[0038] In this embodiment, since the lifting bracket 81 is located on the outer periphery of the feed tray 2, it will limit the maximum diameter of the buffer bin 1 and the feed tray 2, and the corresponding feed pipe 3 is a bent pipe.

[0039] Furthermore, in this embodiment, the acceleration mechanism 8 also includes a transmission scraper 83 located on the lower side of the mounting base 5. The transmission scraper 83 has a guide channel 84 through which the push rod 82 passes. The transmission scraper 83 can scrape away excess micro-pieces 10, and the internal guide channel 84 can provide guidance for the push rod 82, ensuring that the push rod 82 can accurately extend into the metering hole 72, while increasing the rigidity of the push rod 82.

[0040] Example 2

[0041] Figure 5 Another embodiment of the solid filling device of the present invention is shown. The solid filling device in this embodiment is largely the same as that in the previous embodiment, except that:

[0042] In this embodiment, the acceleration mechanism 8 includes an acceleration chamber 85 located on the lower side of the mounting base 5, and the acceleration chamber 85 is connected to an inflation pipe 86. When high-speed transmission of micro-chips 10 is required, a high-pressure air blowing method is used to blow all the micro-chips 10 in the metering orifice 72 into the empty capsule 20 below, thereby meeting the high-speed filling requirements.

[0043] In this embodiment, since there is no need to install a lifting bracket 81 on the outer periphery of the feed tray 2, both the buffer bin 1 and the feed tray 2 can be expanded to directly above the metering hole 72 on the metering tray 7, and the corresponding feed pipe 3 can be a straight pipe. (Comparison) Figure 1 and Figure 6 This embodiment can share some lower components with the powder filling equipment, such as the mounting base 5, metering plate 7, rotating tower 71, and sliding plate 6, without the need for separate design of special equipment, which helps to reduce costs, is convenient and effective.

[0044] While the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the invention. Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the scope of the present invention, should fall within the protection scope of the present invention.
