Abstract
Description
Technical Field
[0001] This utility model relates to the field of pet freeze-drying screening technology, and in particular to a pet freeze-drying screening device. Background Technology
[0002] Freeze-dried pet food is gaining popularity due to its ability to retain nutrients and original flavor to the greatest extent. During the production process, freeze-dried products often vary in size and require sieving to separate whole particles, fragments, and powder, thereby meeting the packaging requirements of different product grades and enhancing product value.
[0003] Common screening equipment may experience inconsistent feed rates. Excessive feed rates, coupled with the inlet typically being fixed in the center, can lead to material accumulation in the central area of the screen, resulting in an excessively thick material layer and overloaded screen, while the edge areas have low utilization rates. This leads to low screening efficiency, easy clogging, and severe localized wear on the screen. Furthermore, the screen's tilt angle is usually non-adjustable, making it impossible to optimize for material characteristics (such as particle size, moisture content, and viscosity) and screening requirements (such as balancing screening accuracy and throughput). For freeze-dried products with varying flowability, a fixed screening angle cannot simultaneously achieve both screening efficiency and accuracy, resulting in poor equipment applicability. Therefore, a pet freeze-drying screening device is proposed. Utility Model Content

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0023] Example
[0024] like Figures 1 to 5 As shown, the present invention proposes a pet freeze-drying sieving device, including a housing 1. A feeding mechanism 2 is provided on the top surface of one side of the housing 1, a sieving mechanism 3 is provided on the right side of the housing 1, and a support assembly 4 is provided at the bottom of the housing 1. The support assembly 4 includes a support plate 41, a plurality of legs 42 are provided on the top surface of the support plate 41, the legs 42 are fixedly connected to the support plate 41, a vibrating seat 43 is provided at the top of each leg 42, the bottom surface of the vibrating seat 43 is fixedly connected to the leg 42, and the vibrating seat 43 is fixedly connected to both sides of the housing 1. Through the setting of the support assembly 4, the housing 1 can be sieving. 1. The feeding mechanism 2 plays a supporting role during vibration. It includes a motor 5 installed inside the housing 1 and a protective cover 6 installed on the top surface of the housing 1. Both the motor 5 and the protective cover 6 are fixedly connected to the housing 1. The top surface of the protective cover 6 is provided with a feed pipe 7, which extends through the protective cover 6 and is fixedly connected to the protective cover 6. The protective cover 6 can prevent dust generated when freeze-dried materials are fed into the workshop environment, thus preventing occupational health problems of production personnel and reducing pollution to the production environment. At the same time, it provides fixed support for the feed pipe 7.
[0025] The output end of motor 5 is equipped with a feeding disc 8, which is fixedly connected to the output end of motor 5. A sleeve 81 is provided on the bottom surface of the feeding disc 8, which is fixedly connected to the bottom surface of the feeding disc 8 and rotatably connected to the inside of the housing 1. With the arrangement of motor 5, feeding disc 8 and sleeve 81, motor 5 starts, and the feeding disc 8, which is fixedly connected to motor 5, rotates under the drive of motor 5. The rotation of the feeding disc 8 drives the fixedly connected sleeve 81 to rotate. The sleeve 81 can prevent the feeding disc 8 from shaking due to centrifugal force or gravity during rotation, and adds support to the feeding disc 8 to ensure the smooth rotation of the feeding disc 8. It can also protect motor 5 and prevent damage to the motor shaft.
[0026] A material control component 9 is installed on the top surface of the feeding disc 8. The material control component 9 includes a baffle 91 installed on the top surface of the feeding disc 8. The baffle 91 is fixedly connected to the top surface of the feeding disc 8. A cylinder 92 is installed inside the baffle 91. The cylinder 92 is fixedly connected to the feeding disc 8. The moving rod of the cylinder 92 passes through the baffle 91 and is connected to a material distribution buffer plate 93. The material distribution buffer plate 93 is made of rubber and can buffer the impact of materials to avoid physical damage during the material feeding process and reduce losses. The material distribution buffer plate 93 is fixedly connected to the moving rod of the cylinder 92. The material distribution buffer plate 93 is located directly below the feed pipe 7 and abuts against the bottom end of the feed pipe 7. During the screening process, the material is fed in through the feed pipe 7. When the material reaches the distribution buffer plate 93, the cylinder 92 is activated. The movable rod of the cylinder 92 retracts, causing the fixedly connected dispersion buffer plate 93 to descend. The dispersion buffer plate 93 separates from the feed pipe 7. The material can be dispersed into a uniform layer or flow by the distribution buffer plate 93. Through the curvature of the top surface of the dispersion buffer plate 93, the material slides evenly along the edge of the dispersion buffer plate 93 to the feeding disc 8, avoiding local accumulation and ensuring smooth feeding. With the cooperation of the baffle 91, the boundary of the material conveying can be defined, preventing the formation of dead corners for material accumulation. It also provides a certain degree of protection for the cylinder 92 set inside the baffle 91, preventing the material from directly contacting the cylinder 92 and reducing the maintenance frequency and failure rate of the cylinder.
[0027] A feed inlet is provided on the side of the protective cover 6 near the screening mechanism 2, and a scraper 10 is provided. The scraper 10 is fixedly connected to the protective cover 6. By setting the scraper 10 and adjusting the speed of the motor 5, the material can be fed into the next screening step at a uniform speed. A guide hopper 11 is set at the position corresponding to the feed inlet. The guide hopper 11 is fixedly connected to the protective cover 6. A distribution plate 18 is set inside the guide hopper 11. The distribution plate 18 is fixedly connected to the guide hopper 11. By setting the distribution plate 18 inside the guide hopper 11, the material entering from the feed inlet can be evenly dispersed, avoiding the material from accumulating in a certain area of the guide hopper 11, preventing local congestion, and ensuring smooth material flow. The material dispersed by the distribution plate 18 can enter the subsequent screening mechanism 3 more evenly, avoiding the impact of excessive local material on screening efficiency and effect. At the same time, it can also reduce the impact of material on the guide hopper 11 and the screening mechanism 3, reduce equipment wear, and extend service life.
[0028] The screening mechanism 3 includes two screen plates 12 arranged from top to bottom inside the housing 1. The screen plates 12 are slidably disposed inside the housing 1 and are slidably connected to the housing 1. Both screen plates 12 are inclined in opposite directions. The upper screen plate 12 is a coarse screen. If it is inclined to the left, when the material slides down the inclined direction of the screen plate 12, the first coarse screening and separation of large particles is completed. The lower screen plate 12 is a fine screen. If it is inclined to the right, the material falling from the end of the upper screen plate 12 needs to slide down the opposite inclined surface again. At this time, the remaining medium and small particles have more time to contact the screen holes. The fine particles can pass through the screen holes more fully, while the medium particles are... The lower screen plate 12 traps small particles, which fall onto the bottom plate of the box 1. The materials trapped by different screen plates 12 are discharged from the corresponding discharge ends of the screen plates 12. Each screen plate 12 has a baffle strip 19 on its edge. The baffle strip 19 is arranged in an inner arc shape and is fixedly connected to the screen plate 12. The baffle strip 19 is tightly attached to the inner wall of the box 1. The baffle strip 19 can prevent material accumulation. The tight attachment of the baffle strip 19 to the inner wall of the box 1 also prevents material from falling into the lower screen plate through the gap between the screen plate 12 and the box 1 during the vibrating screening process, thus affecting the screening quality.
[0029] Each screen plate 12 is provided with an adjusting component 13 on one side. Each adjusting component 13 includes a second motor 131 installed inside the housing 1. The second motor 131 is fixedly connected to the housing 1. A threaded rod 132 is connected to the output end of the second motor 131. The threaded rod 132 is fixedly connected to the second motor 131. A pad 20 is provided at one end of the threaded rod 132. The threaded rod 132 and the pad 20 are rotatably connected. The upper pad 20 is fixedly connected to the guide hopper 11, and the lower pad 20 is fixedly connected to the discharge hopper 14. An adjusting block 133 is threadedly connected to the outer ring of the threaded rod 132. A connecting block 134 is provided on one side of the adjusting block 133. The connecting block 134 is connected to the adjusting block 133. Block 133 is fixedly connected. A connecting shaft 135 is rotatably installed inside the connecting block 134. The connecting block 134 has a rotating hole inside. The connecting shaft 135 is rotatably connected to the connecting block 134 through the rotating hole. Connecting blocks 136 are rotatably installed on the outer rings of both ends of the connecting shaft 135. Connecting blocks 136 are rotatably connected to the connecting shaft 135. Connecting blocks 136 are fixedly connected to the sieve plate 12. By setting the adjustment component 13, the angle of the sieve plate 12 can be electrically adjusted to adapt to materials of different densities. For example, for low-density freeze-dried flakes, the angle is adjusted to a larger angle to accelerate the flow, and for high-density granules, the angle is adjusted to a smaller angle to avoid impact. This optimizes the residence time of the material on the sieve plate 12 and avoids insufficient sieving or excessive impact.
[0030] A discharge hopper 14 is provided on the other side of the screen plate 12. The contact area between the screen plate 12 and the discharge hopper 14 is always in abutting state. A guide assembly 15 is provided on the bottom surface of the screen plate 12 near the discharge hopper 14. The guide assembly 15 includes a fixed rod 151 provided inside the housing 1 and a U-shaped guide block 152 provided on the bottom surface of the screen plate 12. The fixed rod 151 is rotatably connected to the housing 1, and the U-shaped guide block 152 is fixedly connected to the screen plate 12. Two sliding blocks 153 are provided on the outer ring of the fixed rod 151. The sliding blocks 153 are rotatably connected to the fixed rod 151. The U-shaped guide block 152 has a sliding groove 154 corresponding to the position of each sliding block 153. The screen plate 12 is dynamically installed in the sliding groove 154. Through the setting of the guide component 15, the guide component 15 can guide and limit the screen plate 12 when the angle is adjusted, so that the screen plate 12 will not be dislodged during the adjustment process. A discharge hopper 2 16 is set on one side of the bottom plate of the box 1. The discharge hopper 2 16 is fixedly connected to the bottom plate of the box 1. The box 1 has a discharge port for each discharge end. A vibration motor 17 is set on the bottom surface of the bottom plate of the box 1. The box 1 is fixedly connected to the vibration motor 17. The setting of the vibration motor 17 provides a vibration source for the screening mechanism 3. The problem of poor adaptability can also be solved by adjusting the vibration frequency of the vibration motor 17, thereby improving the equipment's versatility and scene matching.
[0031] In this embodiment, during the screening process, the material is fed onto the distribution buffer plate 93 through the feed pipe 7. The vibration motor 17 starts, and the cylinder 92 starts. The movable rod of the cylinder 92 retracts, causing the fixedly connected dispersion buffer plate 93 to descend. The dispersion buffer plate 93 separates from the feed pipe 7, and the material can be dispersed into a uniform layer or flow by the distribution buffer plate 93. Through the curvature of the top surface of the dispersion buffer plate 93, the material slides evenly along the edge of the dispersion buffer plate 93 onto the feeding disc 8. The motor 5 starts, and the feeding disc 8, which is fixedly connected to the motor 5, rotates under the drive of the motor 5. The scraper 10 on the feeding disc 8 conveys the material to the guide hopper 11, and the material is then conveyed from the guide hopper 11 to the upper screen plate 12. The material slides down the inclined direction of the screen plate 12, completing the first coarse screening. Large particles are separated. The material falling from the end of the upper screen plate 12 slides down the reverse inclined surface again. Medium particles are intercepted by the lower screen plate 12, and small particles fall into the bottom plate of the box 1 through the lower screen plate 12. When it is necessary to adjust the angle of the screen plate 12, the second motor 131 is started. The output end of the second motor 131 drives the threaded rod 132 to rotate. The rotation of the threaded rod 132 drives the threaded adjustment block 133 to move up and down. The movement of the adjustment block 133 drives the fixed connection connecting block 134 to move. The connecting block 134 drives the second connection block 136 to move. The second connection block 136 drives the fixed connection screen plate 12 to move up and down, thereby realizing the angle adjustment of the screen plate 12. When the angle of the screen plate 12 is adjusted, the sliding block 153 slides in the sliding groove 154 to prevent the screen plate 12 from dislodging when adjusting the angle.
