Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fish feed, in particular to a fish feed packaging device. BACKGROUND

[0002] With the development of aquaculture, more and more fish production is needed to be fed by feeding to grow faster to meet market demand. At present, most of the fish feed is in the form of granules, which is put into the fish pond of the cultivated fish by feeding, so that the fish can eat. After the preparation of the feed, it needs to be packaged and packaged. Due to market requirements, the feed needs to be packaged and packaged quantitatively, that is, the content of each bag of feed should be consistent with the standard. In this way, it is convenient for market sales and convenient for breeders to judge the feeding of fish according to the weight of each bag of feed. Therefore, after the preparation of the feed, how to quantitatively package and package becomes an important process in the preparation of the feed. Since most of the feed is in the form of granules, the conveying equipment of the conveying belt is used to place and support the corresponding packaging bag during the packaging and packaging. The packaging bag is sent to the outlet below the screw conveyor by the conveying equipment of the conveying belt, and the feed is quantitatively fed into the packaging bag by the screw conveyor. The way to determine the weight of the feed in the packaging bag is to set a weighing device below the packaging bag. When the feed is fed into the packaging bag, the amount obtained by the weighing device is used to determine whether the screw conveyor is stopped. However, due to the hysteresis of the screw conveyor, that is, when the feed in the packaging bag reaches the set weight, the signal is given to the screw conveyor, and the screw conveyor stops rotating. However, since the opening of the packaging bag needs to be upward, the output end of the screw conveyor will be bent downward by a part so as to better align the opening of the packaging bag, and the feed in the output end of the screw conveyor will continue to fall under the action of gravity when the screw conveyor stops, so as to cause the feed in the packaging bag to be greater than the pre-set weight, thereby causing the packaged feed to be inaccurate in quantity and affecting use.

After the spreading assembly passes above the top of the measuring hopper 5, the excess feed is scraped off and falls on the conveying belt 3 on both sides of the measuring hopper 5. Since the feed on the measuring hopper 5 is scraped from front to back, there is no feed on the front side of the measuring hopper 5. Therefore, the cleaning plate 28 is arranged on both sides of the measuring hopper 5 to scrape the feed on the conveying plate and prevent the excess feed from entering the lower hopper 4 to affect the weight of the package. The height of the cleaning plate 28 is set in combination with the stacking height of the feed.

Since the top of the conveying belt 3 needs to be used in cooperation with the flattening assembly, the horizontal position of the quantitative hopper 5 needs to be ensured. When the conveying belt 3 is conveyed to the upper horizontal position, the crosspiece 35 enters the strip-shaped groove 34 to horizontally and stably support the upper side of the conveying belt 3, thereby ensuring the horizontal effect of the conveying belt 3 on the upper side and improving the use reliability of the quantitative hopper 5. Through the design of the crosspiece 35 on the lower side, the conveying belt 3 on the lower side is prevented from sagging under the action of the quantitative hopper 5, thereby improving the service life of the conveying belt 3.

[0091] In summary, the fish feed packaging device needs to be noted that the conveying belt 2 is a known device that can position and convey and support the packaging bag. The internal structure and function of the existing conveying belt 2 are not improved in the application, and the feed rationing problem before packaging is improved. Therefore, the structure of the application is directly installed on the existing packaging bag conveying belt 2 device for use. The conveying belt 2 is provided with a corresponding packaging bag support assembly, which is not described herein. First, the prepared feed is loaded into the hopper 23, and then the weight of the feed to be packaged is combined, for example, 30 kg. The capacity of the quantitative hopper 5 is set to 10 kg. The conveying motor 37 is set to intermittently drive three quantitative hoppers 5 into the lower hopper 4. The conveying belt 2 is set to move once every three quantitative hoppers 5 in the lower hopper 4. That is, the packaging bag at the bottom of the lower hopper 4 moves once after receiving three times of quantitative hopper 5. Thus, each packaging bag can accurately package 30 kg of feed. Since the prepared aquatic feed is dry, and the space of the lower hopper 4 is much larger than that of the quantitative hopper 5, the feed in the quantitative hopper 5 basically will not hang or accumulate in the lower hopper 4, thereby ensuring the accuracy of each packaging feed. The excess feed is recycled into the hopper 23 for continuous addition and use. In order to avoid the accumulation of feed in the lower hopper 4, an air pipe can be arranged on the inner wall of the lower hopper 4 along the inner direction of the lower hopper 4. The air pipe penetrates the outer wall of the lower hopper 4 and is connected with the air pump. The air pump blows air to blow and dredge the accumulated position at the bottom of the lower hopper 4. The blowing device can be optionally installed.

[0092] While embodiments of the present application have been shown and described, it is to be understood that various modifications, substitutions, replacements and variations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
