Description

Technical Field

[0001] This utility model relates to the field of batching scale technology, specifically to a batching scale spiral blade variable diameter feeding mechanism. Background Technology

[0002] A batching scale is an industrial weighing device used for the precise and automated weighing of various raw materials. It typically consists of multiple weighing hoppers (or containers), high-precision sensors, feeding devices (such as vibrating feeders, screw conveyors, and valves), and an intelligent control system. Its core function is to automatically, continuously, or batch-wise mix different types and proportions of materials according to preset formula requirements, quickly and accurately. Batching scales are widely used in food processing, feed production, chemical, pharmaceutical, building materials (concrete, asphalt), and rubber and plastics industries. They are key equipment for achieving production automation, ensuring consistent product quality, improving efficiency, and reducing raw material waste. Their accuracy requirements are typically very high (e.g., ±0.1%), and they must be adaptable to the characteristics of different materials (e.g., flowability, particle size, moisture content).

[0003] A batching scale requires a dedicated feeding mechanism, which is the core design for achieving automated, high-precision, and high-efficiency batching. The feeding mechanism plays a role far beyond simply "discharging materials," but rather in the precise control of the entire batching process. However, in a conical hopper, materials naturally accumulate due to gravity, and the material near the hopper wall has poor flowability (forming a "dead zone"). Especially when the hopper outlet is small, blockages are prone to occur. To address this, we propose a batching scale with a variable-diameter spiral blade feeding mechanism. Utility Model Content

[0004] The purpose of this utility model is to provide a variable diameter feeding mechanism for a batching scale with spiral blades, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A feeding mechanism for a batching scale with variable diameter spiral blades includes: a protective shell, a rotatably connected cover to the top of the protective shell, and an opening handle fixedly connected to the top of the cover; characterized in that: an anti-adhesion component is fixedly connected to the bottom of the protective shell, the size of the anti-adhesion component matches the inner wall of the protective shell, multiple flat components are fixedly connected to the surface of the anti-adhesion component, connecting blocks are evenly distributed on the bottom surface of the multiple anti-adhesion components, and a support leg is fixedly connected to the bottom of each connecting block.

[0007] Preferably, the anti-adhesion assembly includes a cone hopper, a spiral blade body, a mounting hole, a rotating central shaft, a drive motor, a protective shell, a dredging connecting plate, and a side scraper. The cone hopper is fixedly connected to the bottom of the protective shell, and the spiral blade body is disposed on the inner wall of the cone hopper, with the size of the spiral blade body matching the inner wall of the cone hopper.

[0008] Preferably, the mounting hole is formed on the inner wall of the helical blade body, the rotating central shaft is fixedly connected to the inner wall of the mounting hole, the drive motor is fixedly connected to the top of the rotating central shaft, the protective shell is fixedly connected to the top of the rotating central shaft, and the drive motor is disposed on the inner wall of the protective shell.

[0009] Preferably, a plurality of the unblocking connecting plates are fixedly connected to the surface of the rotating central shaft, and the side scraper is fixedly connected to one end of the unblocking connecting plate. The size and position of the side scraper match the inner wall of the protective shell.

[0010] Preferably, the plurality of the paving components include a connecting drain plate, a paving plate, a movable spring, a movable scraper, and a rotating movable shaft, wherein the connecting drain plate is fixedly connected to the bottom surface of the rotating central shaft, and the paving plate is fixedly connected to both sides of the connecting drain plate.

[0011] Preferably, the movable scraper is rotatably connected to one end of the connecting drain plate, the rotating movable shaft is fixedly connected to one side of the movable scraper, and the movable spring is fixedly connected between the flat plate and both sides of the rotating movable shaft.

[0012] Preferably, the bottom of the plurality of support legs is fixedly connected with a connecting pad.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The anti-adhesion component can prevent the accumulation and blockage of fallen materials by utilizing its own structure. At the same time, by using its own structure in conjunction with the structure of the flattening component, the material is fed in a flat and active feeding motion, thereby further preventing accumulation and improving the functionality and safety of the device. The connecting block can help to use its own structure to combine with the bottom support legs to support the entire device.

[0015] 2. The anti-adhesion component structure facilitates material feeding, allowing the outer diameter of the spiral blade to gradually change along the material flow direction (from the feed end to the discharge end) to closely fit the inner wall contour of the cone hopper, eliminating or minimizing the gap between the blade and the hopper wall for material feeding. Simultaneously, a rotating shaft is installed in the mounting hole, rotating under the action of the drive motor at the top of the rotating shaft, thus completing the basic rotation function. The rotating spiral blade further assists in material feeding and prevents blockage and accumulation. The protective shell helps protect the surface of the drive motor to prevent the material feeding from affecting the drive motor. At the same time, the unblocking connecting plate, under the action of the rotating shaft, drives the side scraper to continuously scrape the inner wall of the protective shell, preventing some dusty and fine materials from accumulating on the inner wall, thereby further improving the functionality and cleanliness of the device.

[0024] 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.

[0025] Please see Figures 1-5 This utility model provides a technical solution:

[0026] A feeding mechanism for a batching scale with variable diameter spiral blades includes: a protective shell 1, a sealing cover 2 rotatably connected to the top of the protective shell 1, and an opening handle 3 fixedly connected to the top of the sealing cover 2. The protective shell 1 is characterized by having an anti-adhesion component 4 fixedly connected to its bottom, the anti-adhesion component 4 having dimensions matching the inner wall of the protective shell 1, multiple flat components 5 fixedly connected to the surface of the anti-adhesion component 4, connecting blocks 6 evenly distributed on the bottom surface of the multiple anti-adhesion components 4, support legs 7 fixedly connected to the bottom of each connecting block 6, and connecting pads 8 fixedly connected to the bottom of the multiple support legs 7.

[0027] In this embodiment, the protective shell 1 helps to protect the entire device from the surface, thereby further improving the protective performance of the device. The sealing cover 2 can help to seal the internal structure of the protective shell 1 when the device is not in use. The opening handle 3 can help to provide a point of force for opening the sealing cover 2. The anti-adhesion component 4 can use its own structure to help guide the feed, prevent the conveyed material from accumulating, and prevent the material from sticking to the inner wall of the protective shell 1, thereby further improving the functionality of the device. At the same time, it works with the flattening component 5 to flatten the feed for easy conveying and further enhance the conveying effect. The connecting block 6 can support the device from the surface and the support leg 7 at the same time. The connecting pad 8 can support the support leg 7 from the bottom, increasing the force-bearing area at the bottom, thereby increasing the overall stability of the device.

[0028] The anti-adhesion assembly 4 includes a cone hopper 401, a spiral blade body 402, a mounting hole 403, a rotating central shaft 404, a drive motor 405, a protective shell 406, a dredging connecting plate 407, and a side scraper 408. The cone hopper 401 is fixedly connected to the bottom of the protective shell 1, and the spiral blade body 402 is disposed on the inner wall of the cone hopper 401. The size of the spiral blade body 402 matches the inner wall of the cone hopper 401.

[0029] In this embodiment, the anti-adhesion component 4 uses the cone hopper 401 to make the outer diameter of the spiral blade body 402 gradually change along the material flow direction (from the feed end to the discharge end) so as to closely fit the inner wall contour of the cone hopper 401, eliminate or minimize the gap between the blade and the hopper wall for feeding, thereby preventing the material from accumulating. By increasing this curved path transportation method, the feeding effect and the utilization rate of the material are improved.

[0030] Mounting hole 403 is formed on the inner wall of the spiral blade body 402. Rotation shaft 404 is fixedly connected to the inner wall of mounting hole 403. Drive motor 405 is fixedly connected to the top of rotation shaft 404. Protective shell 406 is fixedly connected to the top of rotation shaft 404. Drive motor 405 is set on the inner wall of protective shell 406.

[0031] In this embodiment, the mounting hole 403 helps to connect the rotating central shaft 404 to the spiral blade body 402, while the drive motor 405 is connected to the rotating central shaft 404, thereby driving the rotating central shaft 404 to rotate, which in turn drives the spiral blade body 402 to rotate, assisting in feeding. The protective shell 406 can protect the drive motor 405 from falling materials, thereby further improving the functionality and safety of the device.

[0032] Multiple unblocking connecting plates 407 are fixedly connected to the surface of the rotating central shaft 404, and a side scraper 408 is fixedly connected to one end of the unblocking connecting plate 407. The size and position of the side scraper 408 match the inner wall of the protective shell 1.

[0033] In this embodiment, the unblocking connecting plate 407 can rotate under the action of the rotating central shaft 404, thereby driving the side scraper 408 to move on the inner wall of the protective shell 1 to prevent materials from sticking to the inner wall of the protective shell 1, further preventing material accumulation and improving the overall material conveying efficiency of the device.

[0034] Multiple paving components 5 include a connecting drain plate 501, a paving plate 502, a movable spring 503, a movable scraper 504, and a rotating movable shaft 505. The connecting drain plate 501 is fixedly connected to the bottom surface of the rotating central shaft 404, and the paving plate 502 is fixedly connected to both sides of the connecting drain plate 501.

[0035] In this embodiment, the spreading component 5 is fixed to the bottom of the rotating central shaft 404 by the connecting unblocking plate 501. During the rotation with the rotating central shaft 404, it can drive the spreading plate 502 to spread and transport a small amount of material remaining on the top of the spiral blade body 402, so as to prevent the material from accumulating and affecting the subsequent material conveying, thereby further improving the material conveying effect of the device.

[0036] The movable scraper 504 is rotatably connected to one end of the connecting drain plate 501, the rotating movable shaft 505 is fixedly connected to one side of the movable scraper 504, and the movable spring 503 is fixedly connected between the flat plate 502 and both sides of the rotating movable shaft 505.

[0037] In this embodiment, the movable scraper 504, in conjunction with the rotating movable shaft 505 and the limiting position of the flat plate 502, can sway slightly under the action of centrifugal force during rotation. While scraping off the residual material inside the protective shell 1, it also works with the movable spring 503 to achieve a slight vibration effect. This vibrates the material scraped off the surface of the movable scraper 504 to fall off, preventing it from accumulating on the surface of the movable scraper 504 and further improving the material conveying effect of the device.

[0038] Working Principle: The device uses a protective shell 1 to provide basic external protection for the entire device. Meanwhile, the sealing cover 2 can seal the inside of the protective shell 1 from the top when the device is not in use, preventing dust accumulation and further improving the device's functionality and cleanliness. The handle 3 provides a point of leverage for opening the sealing cover 2. The anti-sticking component 4 uses its own structure to prevent fallen materials from accumulating and clogging. It also uses its own structure in conjunction with the flattening component 5 to flatten and feed materials during insertion, further preventing accumulation and improving the device's functionality and safety. The connecting block 6 uses its own structure to connect with the bottom support leg 7, supporting the entire device and further improving its stability. The connecting pad 8 uses its own structure to support the support leg 7 from the bottom, further improving the device's stability.

[0039] 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.
