[0002] The production process of pet food requires the thorough mixing of various ingredients such as grains, meat meal, vegetable pellets, and nutritional additives to ensure that each serving contains a balanced nutritional composition. A mixing device is an indispensable piece of equipment in the pet food mixing process; its main function is to mechanically agitate and evenly mix the different ingredients.
[0003] Currently, common mixing devices for processing mixed pet food have the following drawbacks: Since materials tend to adhere to the inner wall of the mixing drum during the mixing process, most traditional devices lack a wall scraping function. The raw materials remaining on the inner wall may cause contamination or uneven proportions in subsequent batches. Moreover, cleaning these residues usually requires stopping the machine and using tools to disassemble the fixed components, which further increases the difficulty of maintenance.
[0004] Therefore, a mixing device for processing pet food is needed to address the aforementioned technical deficiencies. Utility Model Content
[0005] The purpose of this invention is to provide a mixing device for processing mixed pet food, so as to solve the problem mentioned in the background art of lacking a wall scraping function and having difficulty cleaning the residue on the inner wall.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a mixing device for processing mixed pet food, comprising a base frame and an inner cylinder. The inner cylinder is fixed at the top of the base frame, and an outer cylinder is provided outside the inner cylinder. A plate frame is mounted on the top edge of the outer cylinder. Adjustment grooves are respectively opened on both sides inside the plate frame. Fixing blocks are embedded in the adjustment grooves respectively. Fixing bolts are fixedly connected between the fixing blocks and the adjustment grooves. A scraping rod is welded to the bottom end of the fixing block. The scraping rod extends into the inner cylinder and abuts against the inner wall of the inner cylinder.
[0007] As a further technical solution of this utility model, the fixing blocks are provided in two sets, and the fixing blocks are symmetrically distributed about the horizontal center line of the plate frame.
[0008] As a further technical solution of this utility model, a stirring motor is fixedly connected to the middle position of the top of the plate frame, and a stirring frame is fixedly connected to the output shaft of the stirring motor. The stirring frame is located between two sets of scraping rods.
[0009] As a further technical solution of this utility model, a geared disc is fixedly sleeved on the bottom of the outer side of the inner cylinder, a side plate is welded to the right side of the top of the base frame, a rotary motor is fixedly connected to one side of the side plate, and a gear is fixedly sleeved on the output shaft of the rotary motor, and the gear meshes with the geared disc.
[0010] As a further technical solution of this utility model, the bottom end of the outer cylinder is open, the inner wall of the outer cylinder is processed with a track, and the outer wall of the inner cylinder is equipped with a roller, the track and the roller forming a rolling connection.
[0011] As a further technical solution of this utility model, four sets of discharge ports are installed at the bottom of the inner cylinder, and each set of discharge ports is equipped with a separate solenoid valve.
[0012] As a further technical solution of this utility model, the top and front side of the base frame are supported by columns, the top of the columns are movably sleeved with a rotating sleeve, the rotating sleeve is fixedly connected to a fixed frame, and one side of the fixed frame extends to the top of the outer cylinder and is fixedly connected to a feed hopper.
[0013] As a further technical solution of this utility model, both the outer cylinder and the inner cylinder are cylindrical, and the outer cylinder and the inner cylinder are concentric circles with the bottom end of the outer cylinder open.
[0014] Compared with the prior art, the beneficial effects of this utility model are: the mixing device for processing mixed pet food not only realizes flexible adjustment for scraping the wall to prevent residue from causing uneven mixing or pollution, and realizes dual power to achieve efficient mixing, but also realizes flexible adjustment of the feeding position;
[0015] (1) By setting up a plate frame, a fixing block, fixing bolts, a scraper rod, and an adjustment groove, when the toothed disc and gear are started together, the inner cylinder rotates inside the outer cylinder. Since the plate frame is fixed outside the outer cylinder, the scraper rod remains stationary relative to the inner cylinder. When the inner cylinder rotates, the inner wall is continuously scraped by the scraper rod, which can efficiently remove the pet food raw materials stuck on the inner wall and prevent residue from causing uneven mixing or contamination. If the scraping function is not needed, the fixing bolts can be loosened and the fixing block can be moved to the side closer to the stirring motor in the adjustment groove, so that the scraper rod is no longer in contact with the inner cylinder and no longer scrapes the inner wall. This solves the problem that traditional stirring devices are difficult to clean the inner wall, avoids the tedious operation of manual scraping, and reduces the equipment cleaning time.
[0016] (2) By setting up a rotary motor, gears, toothed discs, stirring motors, and stirring racks, the device utilizes the concentric circular structure of the inner and outer cylinders to achieve relative rotation. The rotary motor drives the gears to rotate, and the torque is transmitted to the inner cylinder through the toothed discs, causing it to rotate. At the same time, the stirring motor is started to make the stirring rack rotate, stirring the pet food raw materials in the inner cylinder. The relative movement of the inner cylinder and the stirring rack can enhance the mixing effect, improve the turning efficiency of the materials, and make the raw materials of different particles and nutrients fully mixed. Efficient stirring is achieved through dual power.
[0017] (3) The device is equipped with a base frame, columns, feed hopper and rotating sleeve. Two sets of columns are set at the top of the base frame. The top of the columns supports a feed hopper that can be flipped horizontally, which can change the feeding position. During operation, different raw materials or nutritional additives can be put into the two sets of feed hoppers respectively, so that the materials can directly enter the inner cylinder. By adjusting the feeding angle, the precise control of different proportions can be achieved. Attached Figure Description

[0023] 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.
[0024] Please see Figure 1-4 An embodiment of this utility model provides a mixing device for processing mixed pet food, including a base frame 14 and an inner cylinder 12. The inner cylinder 12 is fixed at the top of the base frame 14, and an outer cylinder 11 is provided outside the inner cylinder 12. A plate frame 1 is mounted on the top edge of the outer cylinder 11. Adjustment grooves 21 are respectively opened on both sides inside the plate frame 1. Fixing blocks 2 are embedded in the adjustment grooves 21 respectively. Fixing bolts 3 are fixedly connected between the fixing blocks 2 and the adjustment grooves 21. A scraping rod 19 is welded to the bottom of the fixing block 2. The scraping rod 19 extends into the inner cylinder 12 and abuts against the inner wall of the inner cylinder 12. Two sets of fixing blocks 2 are provided. The fixing blocks 2 are symmetrically distributed about the horizontal center line of the plate frame 1.
[0025] Specifically, such as Figure 1, Figure 2 , Figure 3 and Figure 4 As shown, when the toothed disc 13 and gear 16 are started together, the inner cylinder 12 rotates inside the outer cylinder 11. Since the plate frame 1 is fixed outside the outer cylinder 11, the scraper rod 19 remains stationary relative to the inner cylinder 12. When the inner cylinder 12 rotates, the inner wall is continuously scraped by the scraper rod 19, which can efficiently remove the pet food ingredients stuck on the inner wall and prevent residue from causing uneven mixing or contamination. If the scraping function is not needed, the fixing bolt 3 can be loosened and the fixing block 2 can be moved in the adjusting groove 21 to the side close to the stirring motor 4, so that the scraper rod 19 is no longer in contact with the inner cylinder 12 and no longer scrapes the inner wall.
[0026] A stirring motor 4 is fixedly connected to the middle of the top of the plate frame 1. The output shaft of the stirring motor 4 is fixedly connected to a stirring frame 20. The stirring frame 20 is located between two sets of scraping rods 19. A gear plate 13 is fixedly sleeved on the bottom of the outer side of the inner cylinder 12. A side plate 17 is welded to the right side of the top of the base frame 14. A rotary motor 18 is fixedly connected to one side of the side plate 17. A gear 16 is fixedly sleeved on the output shaft of the rotary motor 18. The gear 16 meshes with the gear plate 13. The bottom of the outer cylinder 11 is open. A track 9 is machined on the inner wall of the outer cylinder 11. A roller 10 is installed on the outer wall of the inner cylinder 12. The track 9 and the roller 10 form a rolling connection.
[0027] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the device utilizes the concentric circular structure of the inner cylinder 12 and the outer cylinder 11 to achieve relative rotation. The rotary motor 18 drives the gear 16 to rotate, and transmits the torque to the inner cylinder 12 through the gear disk 13, causing it to rotate. At the same time, the stirring motor 4 is started to make the stirring frame 20 rotate, which stirs the pet food raw materials in the inner cylinder 12. The relative directional movement of the inner cylinder 12 and the stirring frame 20 can enhance the mixing effect.
[0028] The bottom of the inner cylinder 12 is equipped with four sets of discharge ports 15, each set of discharge ports 15 is equipped with a separate solenoid valve, the top and front side of the base frame 14 are supported by a column 8, the top of the column 8 is movably sleeved with a rotating sleeve 7, the rotating sleeve 7 is fixedly connected to a fixing frame 6, one side of the fixing frame 6 extends to the top of the outer cylinder 11 and is fixedly connected to a feed hopper 5, the outer cylinder 11 and the inner cylinder 12 are both cylindrical cylinders, the outer cylinder 11 and the inner cylinder 12 are concentric circular structures and the bottom of the outer cylinder 11 is open;
[0029] Specifically, such as Figure 1 and Figure 2 As shown, the device has two sets of columns 8 at the top of the base frame 14. The top of the columns 8 supports a horizontally tiltable feed hopper 5, which can change the feeding position. During operation, the two sets of feed hoppers 5 can respectively put in different raw materials or nutritional additives, so that the materials can directly enter the inner cylinder 12 by adjusting the feeding angle.
[0030] Working Principle: During operation, the two sets of feed hoppers 5 can respectively feed different raw materials or nutritional additives, allowing the materials to directly enter the inner cylinder 12. The device utilizes the concentric circular structure of the inner cylinder 12 and the outer cylinder 11 to achieve relative rotation. The rotary motor 18 drives the gear 16 to rotate, transmitting torque to the inner cylinder 12 through the gear disc 13, causing it to rotate. Simultaneously, the stirring motor 4 is started, causing the stirring frame 20 to rotate, stirring the pet food raw materials in the inner cylinder 12. The relative movement of the inner cylinder 12 and the stirring frame 20 enhances the mixing effect. When the gear disc 13 and the gear... After the combined start of the wheel 16, the inner cylinder 12 rotates inside the outer cylinder 11. Since the plate frame 1 is fixed outside the outer cylinder 11, the scraper rod 19 remains stationary relative to the inner cylinder 12. When the inner cylinder 12 rotates, the inner wall is continuously scraped by the scraper rod 19, which can efficiently remove the pet food ingredients stuck on the inner wall and prevent residue from causing uneven mixing or contamination. If the scraping function is not needed, the fixing bolt 3 can be loosened and the fixing block 2 can be moved in the adjusting groove 21 to the side close to the stirring motor 4, so that the scraper rod 19 is no longer in contact with the inner cylinder 12 and no longer scrapes the inner wall.
