Description

Technical Field

[0001] This utility model relates to the field of feed packaging machine technology, specifically to a spiral feeding feed packaging machine. Background Technology

[0002] In the livestock breeding and feed processing industry, the level of automation of medium-dose feed packaging equipment directly affects production efficiency and cost control. Medium-dose feed packaging is usually carried out on a corresponding feed packaging machine. There are many types of feed packaging machines on the market, including semi-automatic and fully automatic ones. Semi-automatic medium-dose packaging machines generally use a spiral feeding method for feeding.

[0003] Screw-feeding feed packaging machines typically use a motor to drive corresponding screw blades, which rotate to convey feed forward. However, most screw-feeding feed packaging machines have large screw blades with a wide pitch. When the error margin is small, the large size and pitch of the screw blades result in a larger amount of feed falling each time they rotate, making precise control difficult and affecting the weight accuracy of each bag of feed, causing inconvenience to the user. Therefore, we propose a screw-feeding feed packaging machine. Utility Model Content

[0004] The purpose of this invention is to provide a spiral feeding feed packaging machine to solve the defects mentioned in the background art.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0025] Please see Figures 1-4This utility model provides a technical solution: a spiral feeding feed packaging machine, including a weighing and packaging machine body 1 and a weighing platform 10 disposed on the weighing and packaging machine body 1. A feeding assembly 2 is disposed on the weighing and packaging machine body 1. The feeding assembly 2 includes a first feeding cylinder 20 and a second feeding cylinder 22 disposed below the first feeding cylinder 20. A discharge pipe 201 is fixedly installed at the discharge end of the first feeding cylinder 20. A first servo motor 21 is fixedly installed at the rear end of the first feeding cylinder 20. A first spiral blade 211 is fixedly installed at the end of the output shaft of the first servo motor 21. The first spiral blade 211 is located inside the first feeding cylinder 20. The second feeding cylinder... The discharge end of the second feeding cylinder 22 is fixedly installed on the discharge pipe 201. The rear end of the second feeding cylinder 22 is fixedly installed with a second servo motor 23. The output shaft end of the second servo motor 23 is fixedly installed with a second spiral blade 231. The second spiral blade 231 is located inside the second feeding cylinder 22. The size of the first spiral blade 211 is larger than that of the second spiral blade 231, and the pitch of the first spiral blade 211 is larger than that of the second spiral blade 231. This allows for segmented coarse conveying and precise metering. The first stage of rapid feeding improves efficiency, while the second stage provides fine control over the amount of material falling. This effectively solves the contradiction between accuracy and efficiency in traditional single-stage spiral feeding, resulting in a smaller metering error rate.

[0026] In this embodiment, a feeding hopper 242 is provided above the first feeding cylinder 20. The feeding ends of the first feeding cylinder 20 and the second feeding cylinder 22 are connected to the feeding hopper 242 through pipes. A vertical pipe 24 is fixedly installed at the feeding end of the first feeding cylinder 20. The vertical pipe 24 is fixedly installed at the bottom end of the feeding hopper 242, so that the feed can enter the first feeding cylinder 20 along the vertical pipe 24. A first discharge valve 241 is fixedly installed on the vertical pipe 24, which can control the discharge amount. A feeding cover 243 is fixedly installed at the top of the feeding hopper 242, which is used for feeding operation.

[0027] Specifically, a first inclined pipe 26 is fixedly installed on the vertical pipe 24, a secondary pipe 27 is fixedly installed at the end of the first inclined pipe 26, a second inclined pipe 28 is fixedly installed at the bottom of the secondary pipe 27, and the end of the second inclined pipe 28 is fixedly installed at the feed end of the second feeding cylinder 22. The first inclined pipe 26 and the second inclined pipe 28 are both inclined downward at 45° to 60°, and the secondary pipe 27 is vertically arranged, so that the material can be distributed to different feeding cylinders as needed.

[0028] Furthermore, a second discharge valve 271 is fixedly installed on the secondary pipe 27, and a feed-pulling plate 261 is fixedly installed on the inner wall of the vertical pipe 24 near the first inclined pipe 26. The tilt angle of the feed-pulling plate 261 is the same as the tilt angle of the first inclined pipe 26. The feed-pulling plate 261 is used to allow some feed to enter the first inclined pipe 26 normally.

[0029] In addition, a top plate 25 is fixedly installed on the inner wall of the top cylinder of the feed hood 243. A stirring motor 251 is fixedly installed at the center of the top surface of the top plate 25. A stirring shaft 252 is fixedly installed at the end of the output shaft of the stirring motor 251. A stirring blade 253 is fixedly installed on the stirring shaft 252. The bottom end of the stirring blade 253 extends into the feed hopper 242. The side of the stirring blade 253 is attached to the inner wall of the feed hopper 242. With the stirring blade 253 attached to the inner wall of the feed hopper 242, the equipment is less prone to clogging when processing materials with high fiber content or agglomerated materials, and the wear frequency of the spiral blades is reduced.

[0030] Finally, it should be noted that the components involved in this utility model, such as the first servo motor 21, the second servo motor 23, and the stirring motor 251, are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection methods should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0031] In use, the spiral feeding feed packaging machine of this utility model first pours feed into the feed hopper 242 through the feed hood 243, starts the stirring motor 251, drives the stirring shaft 252 and stirring blades 253 to break up the lumpy material. During operation, the first servo motor 21 drives the first spiral blades 211 to rotate, and transports the feed through the discharge pipe 201 to the packaging container above the weighing platform 10. When the weight in the packaging container is close to the set value, the first servo motor 21 is stopped, and the second servo motor 23 is started. The second servo motor 23 works and drives the second spiral blades 231 to rotate. The feed enters the second feeding cylinder 22 through the first inclined pipe 26, the auxiliary pipe 27 and the second inclined pipe 28. The second spiral blades 231 perform fine feeding to reduce weight error.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
