Description
Technical Field
[0001] This utility model belongs to the field of pet food processing technology, and in particular relates to a quantitative addition device for pet food processing ingredients. Background Technology
[0002] With the rapid development of the pet industry, the demand for refined and nutritious pet food is increasing. Pet food processing has shifted from traditional manual mixing to industrialized and automated quantitative ingredient production. In the industrialized production of pet food (such as extruded food, kibble food, and prescription food), the quantitative addition of ingredients is the core link that determines the nutritional balance and quality stability of the product. This requires adding and mixing various ingredients such as meat meal, grain meal, vitamin premix, and mineral additives in precise formula proportions to meet the nutritional needs of pets of different ages and breeds.
[0003] Existing pet food processing equipment for quantitative ingredient dispensing often uses auger feeders as the core component for ingredient transport and initial dispensing. These augers use rotating spiral blades to push ingredients from the storage bin to subsequent mixing or forming processes. However, due to unavoidable gaps between the auger feeder's spiral blades and the inner wall of the conveying pipe, ingredients cannot be completely pushed to the target station, resulting in residue. This residue affects the accuracy of the ingredient ratios, and the residual ingredients are prone to moisture absorption, clumping, and mold growth, contaminating the conveying pipes, impacting the hygiene and safety of pet food, and increasing the difficulty and cost of equipment cleaning and maintenance. Summary of the Invention
[0004] The purpose of this utility model is to provide a quantitative ingredient addition device for pet food processing, which solves the problems of inaccurate ingredient ratios, contamination of food hygiene and safety, and increased difficulty and cost of equipment cleaning and maintenance caused by the gap between the spiral blades and the inner wall of the pipe in the existing quantitative ingredient addition device for pet food processing using a screw conveyor.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a quantitative food addition device for pet food processing, including a frame, with several storage boxes fixedly installed in a linear array on the top of the frame, and the discharge end of the storage box is connected to a feeding component. The feeding assembly includes a metering cylinder and a rotating shaft located on the same central axis. The metering cylinder is fixedly installed inside the frame, and the rotating shaft is rotatably installed inside the frame. A sub-cylinder is slidably fitted on the inner circumferential side of the metering cylinder. Both the metering cylinder and the sub-cylinder are designed with single-end openings. A retractable stirring element located at one end of the sub-cylinder is rotatably installed inside the metering cylinder. The rotating shaft passes through the metering cylinder, the retractable stirring element, and the sub-cylinder in sequence.
[0006] The present invention is further configured such that the retractable stirring component includes two side sleeves symmetrically sleeved on the circumferential side of the rotating shaft, the two side sleeves being rotatably connected to the inner end face of the metering cylinder and the outer end face of the dispensing cylinder respectively, and a middle sleeve sleeved on the circumferential side of the rotating shaft being slidably connected between the two side sleeves.
[0007] The present invention is further configured such that a limiting ring is fixedly sleeved on the outer peripheral side of the intermediate sleeve, and the limiting ring and the two outer peripheral sides of the side sleeves are fixedly connected with stirring paddles in a circumferential array.
[0008] The present invention is further configured such that the inner circumferential surfaces of the intermediate sleeve and the two side sleeves are provided with embedding grooves, and the circumferential surface of the rotating shaft is fixedly connected with a connecting key, the connecting key being slidably engaged with the embedding groove.
[0009] The present invention is further configured such that an inlet and a outlet are fixedly connected to the circumferential side of the metering cylinder, a first switching valve is fixedly installed between the inlet and the outlet of the storage tank, and a second switching valve is fixedly installed on the outlet.
[0010] The present invention is further configured such that a hollow connecting rod sleeved on one end of the rotating shaft is fixedly connected to the inner end face of the component cylinder, and an electric push rod is fixedly installed on the inner side of the frame, with the output end of the electric push rod fixedly connected to the hollow connecting rod.
[0011] The present invention is further configured such that a drive motor is fixedly installed on the outside of the frame, and the output end of the drive motor is fixedly connected to the rotating shaft.
[0012] This utility model has the following beneficial effects: This utility model adopts a quantitative structure of "one-to-one correspondence between storage bin and feeding component + sliding adjustment of metering cylinder and dispensing cylinder + synchronous agitation of retractable stirring component", which abandons the design of traditional auger feeder that is prone to residue. By driving the dispensing cylinder to slide through the electric push rod, the metering volume of metering cylinder and dispensing cylinder can be adjusted. In conjunction with the drive motor driving the retractable stirring component to rotate, the stirring paddle disperses the ingredients to ensure uniform filling, thus achieving precise quantitative addition of ingredients.
[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0017] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation
[0018] Please see Figure 1-4 This utility model is a quantitative ingredient addition device for pet food processing, including a frame 1. Several storage boxes 2 are fixedly installed in a linear array on the top of the frame 1. The discharge end of the storage boxes 2 is connected to a feeding component 3. The storage boxes 2 are designed to store different ingredients required for pet food processing, and at the same time continuously and independently supply the corresponding individual feeding component 3. When the feeding component 3 independently receives the ingredients delivered by the corresponding storage box 2, it completes the quantitative measurement and accurate discharge of a single ingredient, ensuring that each ingredient is added independently according to the set ratio.
[0019] Specifically, the feeding assembly 3 includes a metering cylinder 4 and a rotating shaft 7 located on the same central axis. The metering cylinder 4 is fixedly installed inside the frame 1, and the rotating shaft 7 is rotatably installed inside the frame 1. A sub-cylinder 5 is slidably fitted on the inner circumferential side of the metering cylinder 4. Both the metering cylinder 4 and the sub-cylinder 5 are designed with a single-end opening. A retractable stirring element 6 located at one end of the sub-cylinder 5 is rotatably installed inside the metering cylinder 4. The rotating shaft 7 passes through the metering cylinder 4, the retractable stirring element 6, and the sub-cylinder 5 in sequence. The metering cylinder 4 and the dispensing cylinder 5 work together to form an independent metering space with adjustable volume. The precise control of the amount of a single ingredient added can be achieved by adjusting the volume of the metering cylinder 4. The rotating shaft 7 is designed to transmit rotational power to the retractable stirring component 6, causing it to rotate, and at the same time providing stable axial guidance for the extension and retraction of the retractable stirring component 6. The retractable stirring component 6 rotates when a single ingredient enters the corresponding metering cylinder 4, dispersing the ingredient in the metering cylinder 4 and ensuring that the ingredient fills the independent metering space evenly. At the same time, it can extend and retract with the movement of the matching dispensing cylinder 5, adapting to metering cylinders 4 with different volumes, and ensuring effective stirring in different metering spaces of a single feeding component 3.
[0020] Furthermore, the retractable mixing component 6 includes two sleeves 8 symmetrically sleeved on the sides of the rotating shaft 7. The two sleeves 8 are rotatably connected to the inner end face of the metering cylinder 4 and the outer end face of the dispensing cylinder 5, respectively. A middle sleeve 9 sleeved on the sides of the rotating shaft 7 is slidably connected between the two sleeves 8. The side sleeves 8 serve as the two end support components of a single retractable mixing component 6. One end is rotatably connected to the inner end face of the corresponding metering cylinder 4 to ensure that the retractable mixing component 6 is stably installed in the metering cylinder 4. The other end is rotatably connected to the outer end face of the matching dispensing cylinder 5, so that when the dispensing cylinder 5 moves, it can drive the side sleeves 8 to move synchronously, thereby realizing the expansion and contraction of a single retractable mixing component 6 and ensuring adaptation to the metering space changes of a single feeding component 3. The design principle of the middle sleeve 9 is to slide with the two sleeves 8 to form the expansion and contraction structure of a single retractable mixing component 6. When the side sleeves 8 move with the dispensing cylinder 5, the middle sleeve 9 can slide between the two sleeves 8 to ensure that the overall length of a single retractable mixing component 6 can be adjusted according to the volume change of the corresponding metering cylinder 4. A limiting ring 10 is fixedly sleeved on the outer periphery of the middle sleeve 9. The limiting ring 10 and the outer periphery of the two side sleeves 8 are all fixedly connected with stirring paddles 16 in a circumferential array. The limiting ring 10 restricts the sliding range of the middle sleeve 9 and the two side sleeves 8, and provides installation positioning for the stirring paddles 16 on the middle sleeve 9. The stirring paddles 16 stir and disperse the single ingredient in the metering cylinder 4 by rotating, so that the ingredient fills the independent metering space of the metering cylinder 4 evenly, avoids local voids or accumulation, and ensures the accuracy of the metering of the single ingredient. The inner circumferential sides of the middle sleeve 9 and the two side sleeves 8 are provided with embedded grooves 11. The circumferential side of the rotating shaft 7 is fixedly connected with a connecting key 12. The connecting key 12 slides with the embedded groove 11. The embedded groove 11 and the connecting key 12 on the rotating shaft 7 form a key connection structure, which ensures that the rotational power of the rotating shaft 7 can be accurately transmitted to all sleeve components of the individual retractable stirring component 6, driving the retractable stirring component 6 to rotate as a whole. At the same time, the middle sleeve 9 and the two side sleeves 8 are allowed to slide along the axial direction of the rotating shaft 7, without affecting the extension and retraction of the individual retractable stirring component 6, ensuring that the power transmission and structural extension and retraction do not interfere with each other. The metering cylinder has a feed inlet 13 and a discharge outlet 14 fixedly connected to its four sides. A first switching valve is fixedly installed between the feed inlet 13 and the discharge outlet of the storage tank 2. A second switching valve is fixedly installed on the discharge outlet 14 (both the first and second switching valves are rotary valves, which are existing technologies and are not shown in the figure, so they will not be discussed in detail here). A hollow connecting rod 15, sleeved on one end of a rotating shaft 7, is fixedly connected to the inner end face of the component cylinder 5. An electric push rod (which is existing technology and is not shown in the figure, will not be discussed in detail here) is fixedly installed on the inner side of the frame 1. The output end of the electric push rod is fixedly connected to the hollow connecting rod 15. A drive motor (which is existing technology and is not shown in the figure, will not be discussed in detail here) is fixedly installed on the outer side of the frame 1. The output end of the drive motor is fixedly connected to the rotating shaft 7. The operation process of this embodiment is as follows: First, according to the requirements for the addition amount of each ingredient in the pet food formula, for the feeding assembly 3 corresponding to each ingredient, start the electric push rod matched with the feeding assembly 3 on the inner side of the frame 1. The output end of the electric push rod pushes the corresponding hollow connecting rod 15, and the hollow connecting rod 15 drives the dosing cylinder 5 of the feeding assembly 3 to move axially relative to the quantitative cylinder 4 along the rotating shaft 7, so as to adjust the volume of the independent metering space formed between the quantitative cylinder 4 and the dosing cylinder 5 until the set volume for the ingredient is reached. Then, for each ingredient, open the first on-off valve between the feed port 13 of the corresponding feeding assembly 3 and the storage tank 2. The corresponding ingredient stored in the storage tank 2 enters the quantitative cylinder 4 of the feeding assembly 3 through the first on-off valve and the feed port 13. Meanwhile, start the driving motor matched with the feeding assembly 3 on the outer side of the frame 1. The output end of the driving motor drives the corresponding rotating shaft 7 to rotate, and through the cooperation of the connecting key 12 and the embedding groove 11, the rotating shaft 7 drives the side sleeve 8 and the middle sleeve 9 of the retractable stirring member 6 of the feeding assembly 3 to rotate synchronously. The stirring paddles 16 on the side sleeve 8 and the middle sleeve 9 rotate accordingly, stirring and dispersing the single ingredient in the quantitative cylinder 4 to ensure that the ingredient uniformly fills the quantitative cylinder 4. After the ingredient in the quantitative cylinder 4 of a certain feeding assembly 3 reaches the set amount, turn off the driving motor matched with the feeding assembly 3 to stop stirring, then close the first on-off valve of the feeding assembly 3, and then open the second on-off valve on the discharge port 14 of the feeding assembly 3. The quantified ingredient in the quantitative cylinder 4 enters the main feeding pipe through the discharge port 14 and the second on-off valve, completing the quantitative addition of this ingredient. During the discharging process, the retractable stirring member 6 can be driven to rotate by the motor to promote the discharging process. By analogy, after the feeding assemblies 3 corresponding to all ingredients complete quantitative addition in sequence, the main feeding pipe conveys a variety of quantified ingredients to the subsequent processing procedure. During the process that the electric push rod of any feeding assembly 3 pushes the dosing cylinder 5 to move, the dosing cylinder 5 drives the side sleeve 8 rotationally connected therewith to move synchronously along the axial direction of the rotating shaft 7, and the entire retractable stirring member 6 of the feeding assembly 3 realizes telescopic movement through the sliding fit between the middle sleeve 9 and the two side sleeves 8, which ensures that the stirring paddle 16 can always cover the independent metering space in the quantitative cylinder 4, adapt to quantitative cylinders 4 of different volumes, and guarantee the stirring effect of the ingredient.
