Description

Technical Field

[0001] This utility model relates to the field of fishery feed packaging technology, specifically a fishery feed packaging machine with a screening structure. Background Technology

[0002] Fishery feed refers to nutrients specifically provided for aquatic organisms during the aquaculture process, designed to meet their specific needs for growth, reproduction, and health maintenance. Its main components are proteins, fats, carbohydrates, vitamins, and minerals, which are the core elements of aquaculture. Through scientific formulation and processing technology, it balances nutritional supply, economic benefits, and environmental sustainability, thereby promoting the development of efficient and healthy aquaculture.

[0003] A fishery feed packaging machine with a screening structure is an automated device specifically designed for the processing and packaging of aquatic feed. Its working principle is that after the feed enters the packaging machine, it first passes through a screening device to separate particles that meet the specifications, and then it is packaged. This achieves efficient, precise, and clean operation in the final stage of feed production, significantly improving the product quality and production efficiency of aquatic feed.

[0004] Existing fish feed packaging machines with screening structures are used to separate particles of different sizes, removing oversized particles from the fish feed before packaging to ensure uniform feed distribution. This makes it easier to control the amount of feed used during feeding and avoids waste. However, their screening structure mainly relies on the vertical impact between the fish feed and the screen for screening. When processing fish feed with high moisture content or high viscosity, the fine particles of the fish feed are prone to adhering to the screen holes, causing screen blockage and reducing screening efficiency.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] Example 1

[0028] Reference Figure 1-4This is the first embodiment of the present invention, providing a fishery feed packaging machine with a screening structure. It includes a packaging machine body 1, a screening box 2 fixedly installed at the upper center of the packaging machine body 1, a feed funnel 3 fixedly installed at the upper center of one end of the screening box 2, a screening mesh plate 4 made of stainless steel with a mesh diameter of 2mm, an elastic support connecting the screening mesh plate 4 to the screening box 2, and a vibration motor at the bottom of the screening box 2. A cleaning brush 12 is threadedly installed on the upper end of the screening screen plate 4, and the rotation speed of the cleaning brush 12 is from 10 rpm to 30 rpm. A first conical collection hopper 6 is fixedly installed at one side port of the screening box 2 near the upper end of the screening screen plate 4. A second conical collection hopper 7 is fixedly installed at one side port of the screening box 2 near the upper end of the screening screen plate 4. A waste collection box 16 is fixedly installed at the upper end of one side of the packaging machine body 1. A packaging collection funnel 17 is fixedly installed at the center of one end of the packaging machine body 1.

[0029] A rotary motor 15 is fixedly installed on one side of the screening box 2 near one end. The output end of the rotary motor 15 is connected to a threaded screw 8. A control box 18 is fixedly installed at the upper end of the center of one side of the packaging machine body 1. A guide pipe extending into the center of the waste collection box 16 is fixedly installed at the center of one side of the first conical collection hopper 6. A square leakage port is opened at one end of the second conical collection hopper 7.

[0030] A feed packaging component is provided at the center of one end of the packaging machine body 1, near the bottom of the packaging collection funnel 17. A square mounting base 5 is fixedly installed on the upper end of the inner side of the screening box 2, near the screening screen plate 4. A threaded screw 8 is rotatably installed through the center of the inner side of the square mounting base 5. A square nut seat 9 is rotatably installed on the outer side of the threaded screw 8. A non-circular mounting base 10 is fixedly installed on one side of the square nut seat 9.

[0031] When the fish feed packaging machine with a screening structure is in use, the operator first puts the fish feed into the feed hopper 3, and then it falls evenly into the screening box 2 under the action of gravity. At the same time, the vibrating motor fixedly installed at the center of the lower end of the screening box 2 is started, so that the screening screen plate 4 in the screening box 2 vibrates and screens the falling fish feed under the action of the vibrating motor. The coarser fish feed is then transported to the waste collection box 16 through the first conical collection hopper 6 and the guide pipe for further processing, while the fish feed that meets the requirements of the screening screen plate 4 is transported to the packaging collection hopper 17 through the second conical collection hopper 7.

[0032] A feed packaging assembly is provided at the center of one end of the packaging machine body 1, near the bottom of the packaging collection funnel 17. Each packaging assembly is electrically connected to the control box 18. The packaging assembly includes a fish feed placement groove, two symmetrical gathering rollers, and a heat sealer, so that the fish feed packaging bag to be packaged is placed inside the placement groove. A rotatable drawstring clamp is movably installed at the lower end of the inner side of the placement groove, and a weighing sensor is installed inside the drawstring clamp. The weighing sensor is electrically connected to the control box 18.

[0033] When the weight sensor inside the drawstring bag changes due to the fishery feed falling from the packaging collection funnel 17, the elastic body inside the weight sensor deforms. This deformation is sensed by the strain gauge fixed on the elastic body, causing a change in the resistance value of the strain gauge. The bridge circuit becomes unbalanced, thus outputting an electrical signal proportional to the force. This signal is then converted into a digital signal by an analog-to-digital converter and transmitted to the control box 18 to display the weight. This allows for precise adjustment of the weight of the packaged fishery feed. The control box 18 then controls the drawstring bag to open, allowing the packaged bag to fall onto two symmetrical gathering rollers for gathering. After that, it falls onto a heat sealing machine for sealing and then onto an inclined plate for collection by workers.

[0034] During the vibrating screening process of fishery feed, to prevent clogging of the screening screen plate 4, the rotary motor 15 is started synchronously after each screening period. This causes the screw rod 8 to move the square nut seat 9 under the drive of the rotary motor 15. As a result, the irregular mounting seat 10, which is fixedly installed on one side of the square nut seat 9, moves along the tilt angle of the screening screen plate 4. Under the action of the rotating shaft 11, the moving irregular mounting seat 10, driven by the friction with the screening screen plate 4, enables the cleaning brush 12 to roll and clean the fishery feed clogging the surface of the screening screen plate 4. The cleaning brush 12 does not clean the screening screen plate 4 during the vibrating screening process, and the cleaning brush 12 does not vibrate during the cleaning process, ensuring the rotational stability of the cleaning brush 12. The cleaning brush 12 is made of nylon bristles, which ensures wear resistance and does not damage the screening screen plate 4. This avoids clogging of the screen plate 4 mesh due to the processing of fishery feed with high moisture content or high viscosity, further improving the screening efficiency of the screening screen plate 4.

[0035] Example 2

[0036] Reference Figure 1-4This is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that: a rotating shaft 11 is fixedly installed at the inner center of the irregular mounting base 10 near the lower end; a cleaning brush 12 that is in close contact with the upper outer side wall of the screening screen plate 4 is fixedly installed on the outer side wall of the rotating shaft 11; two symmetrical irregularly shaped blocks 13 are fixedly installed at the lower ends of two ports on one side of the irregular mounting base 10; and a cleaning scraper 14 that is in close contact with the outer side wall of the cleaning brush 12 is fixedly installed at the lower ends of one side of the two irregularly shaped blocks 13.

[0037] The rotating shaft 11 drives the cleaning brush 12 to clean the fish feed clogging the mesh of the screening screen plate 4. To ensure that the cleaning brush 12 remains clean during long-term cleaning, a cleaning scraper 14 is fixedly installed at one end of the irregular mounting base 10, closely attached to the outer wall of the cleaning brush 12. This allows the fish feed adhering to the outer wall of the cleaning brush 12 to be scraped off simultaneously with each rotation of the cleaning brush 12 as it cleans the screening screen plate 4. A rotating motor is also provided on one side of the cleaning scraper 14, so that when the cleaning scraper 14 cleans the cleaning brush 12, a motor is installed on one side of the cleaning scraper 14. By starting the rotating motor, the cleaning scraper 14 tilts under the drive of the rotating motor, and comes into contact with the cleaning brush 12 to scrape off the waste material adhering to the cleaning scraper 14. At the same time, the contact pressure between the cleaning scraper 14 and the bristles of the cleaning brush 12 is within an appropriate range, and the scraped waste material falls onto the screening screen plate 4. Through vibration, it falls into the first conical collection hopper 6, and then falls into the waste collection box 16 under the action of gravity through the inclined guide tube for collection. This avoids the situation where the screening screen plate 4 is not clean due to unclean cleaning brush 12, and further improves the cleanliness of cleaning brush 12.

[0038] The remaining structure is the same as that in Example 1.

[0039] 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 the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
