Description

Technical Field

[0001] This utility model relates to the technical field of Chinese medicine granule production equipment, specifically to a feeding component for Angelica sinensis regulating menstruation granules. Background Technology

[0002] Angelica sinensis granules are a very common traditional Chinese medicine. In the production process of Angelica sinensis granules, the feeding assembly is an important structure connecting the granule preparation and packaging processes. Because traditional Chinese medicine granules contain extracts, sugars, etc., their flowability is not as ideal as that of Western medicine granules. They are prone to absorbing moisture or slight clumping. Especially at the material hopper discharge port, an auxiliary feeding structure is needed to prevent the formation of "mouse holes" in the granules, that is, the phenomenon where the granules form a hole in the center while the surrounding area remains stationary.

[0003] A search revealed an automatic feeding device and unblocking unit for pesticide granule production, disclosed in patent application publication number CN221252830U. The device includes a hopper and a cutting pipe fixedly connected to the lower end of the hopper. A hollow cylinder is fixedly connected to the cutting pipe, and a rotating shaft is rotatably connected inside the hollow cylinder. A baffle is fixedly connected to the rotating shaft. By rotating a pull rod, the baffle shakes and flips inside the cutting pipe, allowing stuck pesticide granules to fall off. A second motor drives a hollow stirring drum to rotate inside the hopper, making the hopper less prone to clogging, and even if it is clogged, it can be easily unblocked.

[0004] The aforementioned patent uses a baffle that can sway at the bottom of the hopper in conjunction with a hollow mixing cylinder to prevent hopper blockage through stirring and vibration. However, after the Chinese medicine granules absorb moisture, they tend to stick to the inner wall at the bottom of the hopper, causing the granules to form a hollow center while the periphery remains stationary, which affects the feeding process. Utility Model Content

[0005] The purpose of this utility model is to provide a feeding component for Angelica sinensis regulating granules. By setting a scraping structure at the feeding port of the feeding hopper that can scrape against the inner wall of the feeding hopper, the scraping structure scrapes the discharge port of the feeding hopper. Unlike ordinary stirring structures, the bottom end of this scraping structure is not located in the center of the feeding hopper, so it will not affect the discharge. Moreover, this feeding component can be used in conjunction with a stirring structure. During normal feeding, the scraper is used to move the granules. During maintenance, the scraper is replaced to scrape off the Chinese medicine granules adhering to the inner wall of the bottom of the hopper.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an Angelica sinensis regulating granule feeding assembly, comprising a feeding hopper, wherein the inner wall of the feeding hopper is provided with a scraping structure that can scrape the granules to prevent them from accumulating at the bottom of the feeding hopper, the bottom end of the feeding hopper is provided with a driving structure that can drive the scraping structure to rotate, and the top of the feeding hopper is provided with a limiting structure that limits the top of the rotating frame.

[0007] The scraping structure includes a rotating frame and a fixed plate fixed to the outer wall of the rotating frame. The fixed plate is provided with a scraper and a detachable structure that facilitates the replacement of the scraper with a scraper blade.

[0008] Preferably, the rotating frame includes a top curved tube portion, a middle mounting portion, and a bottom connecting portion, with the fixing plate located in the middle mounting portion, and the top curved tube portion and the bottom connecting portion being integrally formed with the middle mounting portion.

[0009] Preferably, the limiting structure includes an extension edge, which is integrally formed on the top of the hopper. An annular groove is formed on the upper surface of the extension edge, and a slider is slidably connected in the annular groove. The slider is fixedly connected to the top curved tube portion.

[0010] Preferably, the driving structure includes a toothed ring, the bottom connecting part is welded to the inner wall of the toothed ring, and annular bosses are provided on both the upper and lower surfaces of the toothed ring. The inner wall of the bottom of the hopper is provided with a groove for accommodating the toothed ring and a sliding groove for rotating the annular bosses. The sliding groove is provided on the upper and lower surfaces of the groove.

[0011] Preferably, the drive structure further includes a drive motor for driving the gear ring to rotate, the output end of the drive motor is fixed with a gear, the gear meshes with the gear ring, and the outer wall of the bottom end of the hopper is provided with a clearance groove and a mounting bracket for installing the drive motor.

[0012] Preferably, the detachable structure includes a mounting groove for accommodating the scraper and a bolt for fixing the scraper. The mounting groove is located at one end of the fixing plate near the bottom connection part. One end of the bolt passes through the fixing plate and the scraper in sequence and is threadedly connected to both the fixing plate and the scraper.

[0013] Preferably, the detachable structure further includes a pad that allows the scraper to tilt, the pad being integrally formed in the mounting groove, and the other side of the scraper being in close contact with the inclined surface of the pad.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model addresses the characteristics of Angelica sinensis regulating granules, which contain extracts and sugars, making them prone to moisture absorption, clumping, and poor flowability. A dedicated scraping structure is installed on the inner wall of the hopper. This scraping structure adheres to the inner wall of the hopper for scraping, rather than stirring in the central area. It can directly act on the areas where granules are most likely to adhere and stagnate, namely the bottom inner wall of the hopper and the area around the discharge port, avoiding the phenomenon of "a void forming in the center while the surrounding granules remain stationary."

[0016] 2. By setting a toothed ring, the scraper drive is not located in the center of the discharge port, so it will not occupy the space of the discharge port and will not affect the discharge. It can also work in conjunction with the central mixing mechanism such as the hollow mixing drum in the prior art.

[0017] 3. By incorporating a detachable structure, the scraper used for daily loosening can be replaced with a sharp scraper blade. When the equipment is shut down for maintenance or encounters clumps of herbal medicine, the scraper blade can remove the herbal medicine particles adhering to the inner wall of the bottom of the hopper, making cleaning and maintenance convenient.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-12 This utility model provides a technical solution: an Angelica sinensis regulating granule feeding assembly, including a feeding hopper 1, the inner wall of the feeding hopper 1 is provided with a scraping structure 2 that can scrape the granules to prevent the granules from accumulating at the bottom of the feeding hopper 1, the bottom end of the feeding hopper 1 is provided with a driving structure 3 that can drive the scraping structure 2 to rotate, and the top of the feeding hopper 1 is provided with a limiting structure 4 that limits the top of the rotating frame 201.

[0033] The scraping structure 2 includes a rotating frame 201 and a fixing plate 202 fixed to the outer wall of the rotating frame 201. The fixing plate 202 is provided with a scraper 203 and a detachable structure 205 that facilitates the replacement of the scraper 203 with a scraper blade 204.

[0034] The scraping structure 2 consists of a rotating frame 201, a fixed plate 202, a scraper 203, and a detachable structure 205. The rotating frame 201 includes a top curved tube 2011, a middle mounting part 2012, and a bottom connecting part 2013 as supports, driving the fixed plate 202 and the scraper 203 to rotate as a whole. The fixed plate 202 is installed on one side of the rotating frame 201, and the bottom end is provided with a mounting groove 2051 to accommodate the scraper 203. The scraper 203 is pressed and fixed in the mounting groove 2051 by bolts 2052 of the detachable structure 205, and is installed against the inclined surface of the pad plate 2053, so that the scraper 203 is in close contact with the inner wall of the hopper 1 at an inclined angle.

[0035] The rotating frame 201 includes a top curved tube portion 2011, a middle mounting portion 2012, and a bottom connecting portion 2013. The fixing plate 202 is located in the middle mounting portion. The top curved tube portion 2011 and the bottom connecting portion 2013 are integrally formed with the middle mounting portion 2012.

[0036] The limiting structure 4 includes an extension 401, which is integrally formed on the top of the hopper 1. An annular groove 402 is provided on the upper surface of the extension 401. A slider 403 is slidably connected in the annular groove 402. The slider 403 is fixedly connected to the top curved tube 2011.

[0037] The edge 401 is located at the top of the hopper 1. The annular groove 402 is in sliding engagement with the slider 403 fixed to the bent tube part 2011 at the top of the rotating frame 201. This restricts the rotating frame 201 to rotate horizontally only around the axis of the hopper 1, preventing the rotating frame 201 from shaking or shifting radially, and ensuring that the scraper 203 always moves in contact with the inner wall.

[0038] When the drive structure 3 drives the rotating frame 201 to rotate, the scraper 203 continuously scrapes along the conical inner wall of the hopper 1, destroying the adhesion layer of particles on the wall surface, preventing particles from accumulating at the bottom edge to form "rat holes", and avoiding occupying the inner cavity space at the bottom of the hopper 1, as will be described later.

[0039] The drive structure 3 includes a toothed ring 301, the bottom connecting part 2013 is welded to the inner wall of the toothed ring 301, and the upper and lower surfaces of the toothed ring 301 are provided with annular bosses 302. The inner wall of the bottom of the hopper 1 is provided with a groove 303 for accommodating the toothed ring 301 and a sliding groove 304 for rotating the annular bosses 302. The sliding groove 304 is provided on the upper and lower surfaces of the groove 303.

[0040] The toothed ring 301 is embedded in the groove 304 at the bottom of the hopper 1 via an annular boss 302, achieving stable rotation. The drive motor 305 meshes with the toothed ring 301 through the output gear 306, driving the rotating frame 201 to rotate, thus rotating the entire scraping structure 2. The power transmission is located on the periphery of the hopper 1, and the bottom end of the rotating frame 201 is close to the inner wall of the hopper 1, so as not to interfere with the flow of particles at the discharge port of the hopper 1.

[0041] The drive structure 3 also includes a drive motor 305 that drives the gear ring 301 to rotate. A gear 306 is fixed at the output end of the drive motor 305. The gear 306 meshes with the gear ring 301. A clearance groove 308 and a mounting bracket 307 for mounting the drive motor 305 are provided on the outer wall of the bottom end of the hopper 1.

[0042] By creating a clearance groove 308, the gear 306 can pass through the outer wall of the hopper 1 and mesh with the gear ring 301.

[0043] The detachable structure 205 includes a mounting groove 2051 for accommodating the scraper 203 and a bolt 2052 for fixing the scraper 203. The mounting groove 2051 is located at one end of the fixing plate 202 near the bottom connecting part 2013. One end of the bolt 2052 passes through the fixing plate 202 and the scraper 203 in sequence and is threadedly connected to both the fixing plate 202 and the scraper 203. The bolt 2052 passes through the fixing plate 202 and is screwed into the side of the scraper 203 to achieve mechanical fixation. The longitudinal cross-sectional structure of the scraper 203 and the scraper blade 204 is as follows: Figure 11 , Figure 12 As shown.

[0044] The detachable structure 205 also includes a pad 2053 that allows the scraper 203 to tilt. The pad 2053 is integrally formed in the mounting groove 2051, and the other side of the scraper 203 is in close contact with the inclined surface of the pad 2053.

[0045] During daily production, install scraper 203 to loosen particles and prevent accumulation; during maintenance and cleaning, replace scraper 204 to remove the particle adhesion layer.

[0046] When in use, the drive motor 305 starts, and the gear 306 drives the gear ring 301 to rotate. The gear ring 301 is located in the groove 304 at the bottom of the hopper 1 through the annular boss 302, so that it can rotate stably. This causes the rotating frame 201 welded to the inner wall of the gear ring 301 to rotate. The scraper 203 scrapes along the inner wall of the hopper 1 with the rotating frame 201, destroying the particle adhesion layer, eliminating edge accumulation, and the particles fall under gravity and are smoothly discharged through the central area of ​​the hopper 1.

[0047] The limiting structure 4 constrains the trajectory of the rotating frame 201. The extension 401 is located at the top of the hopper 1. The annular groove 402 slides in cooperation with the slider 403 fixed to the bent tube part 2011 at the top of the rotating frame 201, which restricts the rotating frame 201 to rotate horizontally only around the axis of the hopper 1, preventing the rotating frame 201 from shaking or deviating radially, and ensuring that the scraper 203 always moves in contact with the inner wall.

[0048] During maintenance shutdown, remove scraper 203 and replace scraper 204. Start drive motor 305 to make rotating frame 201 drive scraper 204 to fit against the inner wall of hopper 1 to clean the clumps on the inner wall. When replacing scraper 204, loosen bolt 2052 to disengage one end of bolt 2052 from scraper 203, remove scraper 203, insert scraper 204, and loosen bolt 2052 to screw bolt 2052 into scraper 204 to fix scraper 204.

[0049] Unlike the central stirring structure in the prior art, this device can clean the inner wall of the discharge port of the hopper 1, which is prone to moisture absorption or slight caking of Angelica granules. The scraping structure 2 of this device does not occupy additional space at the discharge port of the hopper 1, does not affect smooth discharge, and can work in conjunction with the central stirring mechanism such as the hollow stirring drum mentioned in the background art.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
