Description

Technical Field

[0001] This utility model relates to the technical field of granule injection devices, and in particular to a spoon-type granule injection device. Background Technology

[0002] In the production of frozen desserts (such as ice cream), in order to enrich the taste and enhance the product's appeal, it is often necessary to quantitatively inject granular materials (such as chocolate chips, chopped nuts, fruit pieces, etc.) into the ice cream machine to mix with the ice cream base, forming a filling or garnish. Currently, the mainstream granular filling technologies in the industry are mainly screw-propelled feeding and flip-scoop feeding. Screw-propelled feeding relies on a rotating screw to push the granular material in the storage chamber forward and drop it into the mold or ice cream base through the outlet. Flip-scoop feeding uses a set of rotating scoops to scoop the granular material in the chamber, rotate it to a specific angle, and then pour the material into the target position.

[0003] However, the aforementioned traditional filling technologies have significant shortcomings in application. First, during operation, the granular material is easily crushed and broken (like chocolate chips) under the strong extrusion and mutual friction of the screw, severely damaging the integrity of the granules and resulting in poor appearance, deteriorated taste, and poor product perfection in the final product. Second, the close contact and uneven flow resistance between materials during screw propulsion, coupled with the inherent characteristics of the materials (such as varying shapes and sizes), easily leads to large fluctuations in filling weight and significant weight deviations, affecting not only product specification consistency but also material waste. While the rotating scoop method avoids the strong extrusion of the screw, in actual operation, when the material level in the storage silo drops below the critical level, the scoop may become "empty" or "half-full" due to insufficient material coverage. At low material levels, it is difficult for the material to form a uniform and continuous flow layer. In addition, the mechanical rotation stroke of the scoop is fixed and cannot adapt to the changes in filling conditions caused by the drop in material level. This makes the actual amount of material scooped each time extremely unstable and significantly lower than the target value, which seriously damages the consistency of the product within and between batches. The remaining material in the storage silo is also difficult to clean when the operation stops. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a spoon-type granule filling device, which solves the problem that the weight deviation of products increases significantly under low material levels, seriously affecting product consistency and material utilization.

[0005] According to an embodiment of this utility model, a spoon-type granule filling device includes a chamber, in which a rotating shaft is horizontally rotatably arranged. A drive source capable of driving the rotating shaft to rotate forward and backward is fixedly arranged outside the chamber. Several scoops are fixedly arranged side by side on the rotating shaft. Several arc-shaped grooves are arranged around the rotating shaft at the bottom of the chamber, with each scoop corresponding to one of the arc-shaped grooves. The end of the scoop away from the rotating shaft is separated from the arc-shaped groove. Several discharge ports are also fixedly arranged on one side of the chamber, with each scoop corresponding to one of the discharge ports. The scoop can rotate to engage with the discharge port.

[0006] The technical principle of this utility model is as follows: In use, the drive source drives the scoop to rotate forward and backward to scoop the granular material to the discharge port. During the scooping process, the scoop will move to a high position along the arc-shaped groove. The arc-shaped groove and the scoop surface form a concave arc surface that abuts against each other. The material in the arc-shaped groove will fully cover the scoop under the action of the groove surface, so that the scoop can be completely filled every time it scoops. When the material level drops, the granular material will first fill the arc-shaped groove to facilitate scooping. Even at low material levels, the scoop can still feed the material evenly, ensuring product consistency and material utilization rate.

[0007] Furthermore, the drive source includes a stepper motor, which is fixedly connected to one side of the outer wall of the compartment, and the output shaft of the stepper motor is fixedly connected to the rotating shaft.

[0008] Furthermore, a feeding ramp is fixedly installed on one side of the inner wall of the silo, the top surface of the feeding ramp is inclined inward, and the feeding port passes through the feeding ramp and communicates with the outside.

[0009] Furthermore, a feeding seat is fixedly installed on the outside of the hopper near the bottom of the feeding ramp. Several feeding pipes are fixedly connected to the bottom of the feeding seat, and each feeding pipe passes through the feeding seat and communicates with a feeding port.

[0010] Furthermore, the bottom of the feeding ramp is provided with several clearance grooves, the groove surface of which is larger than the arc surface of the scoop, and the clearance grooves allow the scoop to be inserted and offset.

[0011] Furthermore, the top of the feeding ramp is coaxially provided with an enlarged diameter opening, the diameter of which gradually decreases from top to bottom, and the bottom of the enlarged diameter opening is connected to the feeding port.

[0012] Furthermore, the scoop and the rotating shaft are fixedly connected by a connecting rod, and several slots are provided at the lowest point of the top surface of the feeding ramp, which can be used to insert and abut the connecting rod.

[0013] Furthermore, an inclined discharge ramp is fixedly provided at the connection between the inner wall of the hopper body on the side away from the discharge port and the arc-shaped groove.

[0014] Furthermore, a convex surface with a higher center and lower edges is provided between the two arc-shaped grooves, and the convex surface is arranged around the rotating shaft.

[0015] Compared with the prior art, this utility model has the following beneficial effects: by adopting an arc-shaped groove structure corresponding to the scoop around the bottom of the hopper shaft, and keeping the end of the scoop separate from the arc-shaped groove, the arc-shaped groove can guide the granular material to continuously fill the concave surface of the scoop when the scoop rotates to scoop material. When the material level drops, the granular material will first fill the arc-shaped groove. Even at low material levels, the scoop can still be fully filled, thereby solving the problem of filling volume fluctuation, significantly improving the weight stability and product consistency, and reducing material waste caused by empty or half-full scoops.

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0023] like Figure 1-4As shown in the figure, this utility model embodiment proposes a spoon-type particle filling device, including a chamber 1, which is fixedly installed. Support legs 11 are fixedly installed at the four corners of the bottom of the chamber 1. A rotating shaft 2 is horizontally rotatably installed inside the chamber 1. A drive source capable of driving the rotating shaft 2 to rotate forward and backward is fixedly installed outside the chamber 1. The drive source includes a servo motor, a cylinder or hydraulic cylinder (requiring a rack and pinion mechanism), or a common drive motor (requiring a bidirectional rotary electromagnetic clutch), and other mechanisms capable of driving the rotating shaft 2 to reciprocate forward and backward. In this embodiment, the drive source is a stepper motor 21, which is fixedly connected to one side of the outer wall of the chamber 1. The output shaft of the stepper motor 21 is fixedly connected to the rotating shaft 2. The stepper motor 21 does not require encoder feedback and can precisely control the rotation angle of the rotating shaft 2. Several scoops are fixedly installed side-by-side on the rotating shaft 2. 3. The scoop 3 is fixedly connected to the rotating shaft 2 via a connecting rod 31. Several arc-shaped grooves 13 are provided around the rotating shaft 2 at the bottom of the inner chamber 1. Each scoop 3 has a corresponding arc-shaped groove 13, and the end of the scoop 3 away from the rotating shaft 2 is separated from the arc-shaped groove 13. The curvature of the arc-shaped groove 13 can be set according to actual production needs, preferably so that the groove arc surface can cover the outer arc surface of the scoop 3 as much as possible, thereby reducing the gap between scoops 3 and between scoops 3 and arc-shaped grooves 13, so that the material in the arc-shaped groove 13 can more fully cover the scoop 3 under the action of the groove surface, and the scoop 3 can be more easily and completely filled each time it is scooped. Several discharge ports 122 are also fixedly provided on one side of the inner chamber 1. Each scoop 3 has a corresponding discharge port 122, and the scoop 3 can rotate to engage with the discharge port 122.

[0024] The technical principle of this utility model is as follows: In use, the stepper motor 21 precisely drives the scoop 3 to rotate forward and backward to scoop the granular material to the discharge port 122. During the scooping process, the scoop 3 will move to a high position along the arc groove 13. The arc groove 13 and the scoop surface form a concave arc surface that abuts against each other. The material in the arc groove 13 will fully cover the scoop 3 under the action of the groove surface, so that the scoop 3 can be completely filled every time it scoops material. When the material level drops, the granular material will first fill the arc groove 13 to facilitate the scooping of the scoop 3. Even at a low material level, the scoop 3 can still feed material evenly, ensuring product consistency and material utilization rate.

[0025] This invention employs an arc-shaped groove 13 structure corresponding to the scoop 3, arranged around the bottom of the hopper 1 with a rotating shaft 2, and keeps the end of the scoop 3 separate from the arc-shaped groove 13. This design allows the scoop 3 to continuously fill the scoop 3 with granular material when it rotates to scoop material, using the arc-shaped groove 13. When the material level drops, the granular material will preferentially fill the arc-shaped groove 13, ensuring that the scoop 3 is fully filled even at low material levels. This solves the problem of fluctuating filling volume, significantly improves the stability of weight and product consistency, and reduces material waste caused by empty or half-full scoops.

[0026] like Figure 1-4 As shown, according to another embodiment, a feeding ramp 16 is further fixedly provided on one side of the inner wall of the silo 1. The top surface of the feeding ramp 16 is inclined inward. The purpose of the inclined top surface of the feeding ramp 16 is to facilitate the rolling back of some of the granular material spilled outside the feeding port 122 into the silo 1, thus avoiding material waste. The feeding port 122 passes through the feeding ramp 16 and communicates with the outside. A feeding seat 12 is fixedly provided on the outside of the silo 1 near the bottom of the feeding ramp 16. Several feeding pipes 121 are fixedly connected side by side at the bottom of the feeding seat 12. The feeding pipes 121 and the feeding ports 122 correspond one-to-one. Each feeding pipe 121 passes through the feeding seat 12 and communicates with a feeding port 122. The bottom of the feeding pipe 121 is connected to the filling port of the ice cream machine (not shown in the figure). The filling port corresponds one-to-one with the feeding pipe 121.

[0027] like Figure 5 As shown, according to another embodiment, further, the bottom of the feeding ramp 16 is provided with a plurality of clearance grooves 17. The clearance grooves 17 are preferably set as arc surfaces. The diameter of the groove surface of the clearance groove 17 is larger than the diameter of the arc surface of the scoop 3. The clearance grooves 17 allow the scoop 3 to be inserted and abutted. The position of the clearance groove 17 is the initial position when the scoop 3 scoops. When the scoop 3 is reversed in the arc groove 13 to abut against the scoop 3, it will push the granular material in the arc groove 13 outward. Because the arc surface of the clearance groove 17 is larger, there is more space for the granular material to avoid, thereby preventing the scoop 3 from squeezing and damaging the granular material.

[0028] like Figure 1-4As shown, according to another embodiment, further, the top of the feeding ramp 16 is coaxially provided with an enlarged diameter port 161, which is located at the top of the feeding port 122. The diameter of the enlarged diameter port 161 gradually decreases from top to bottom, and is preferably configured as an arc-shaped funnel structure. The bottom of the enlarged diameter port 161 is connected to the feeding port 122, and the top diameter of the enlarged diameter port 161 is larger than that of the feeding port 122. The larger diameter of the enlarged diameter port 161 makes it easier to receive the granular material in the scoop 3, preventing the material from spilling out of the feeding port 122, which would lead to an increase in the product weight deviation and ensure the consistency of the product within and between batches. Furthermore, the lowest point of the inclined top surface of the feeding ramp 16 is provided with several slots 162. The bottom of the slots 162 is preferably at the same level as the feeding port 122. The slots 162 connect the enlarged diameter port 161 and the inner chamber 1 so that the connecting rod 31 can be inserted and abutted. The position of the slots 162 is the terminal position when the scoop 3 scoops. When the scoop 3 is inserted into the slots 162 and abuts against them, the scoop 3 is inserted into the enlarged diameter port 161, thereby ensuring that all the granular material is put into the feeding port 122.

[0029] like Figure 1-4 As shown, according to another embodiment, further, an inclined feeding ramp 15 is fixedly provided at the connection between the inner wall of the bin body 1 away from the discharge port 122 and the arc-shaped groove 13. The feeding ramp 15 facilitates the return of some granular material that cannot be scooped up by the scoop 3 to the bin body 1, thus avoiding material waste.

[0030] like Figure 1-2 As shown, according to another embodiment, further, the connecting portion between the two arc-shaped grooves 13 is provided with a convex surface 14 that is high in the middle and low at the edges. The shape of the convex surface 14 can be set as a conical surface or an arc surface. The convex surface 14 is arranged around the rotating shaft 2 and has the same length as the arc surface. The convex surface 14 can make the granular material fall into the arc-shaped groove 13 when the material level is low, without accumulating between the arc-shaped grooves 13, further increasing the scooping effect of the scooping spoon 3.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
