Description

Technical Field

[0001] This utility model relates to the field of baling machines, specifically to a wire binding mechanism for a baling machine and its auger. Background Technology

[0002] Fully automatic balers are generally used for compressing and baling waste materials such as waste paper and waste plastics to reduce their volume for easier storage and transportation. They typically use wire to bind the compressed waste bales, preventing them from rebounding and expanding. During the wire baling process, two strands of wire are first hooked together and twisted a certain number of times by a auger. The twisted wire then enters the shearing opening and is cut by the shearing mechanism. The cut wire is then twisted a certain number of times by the auger to complete the baling process.

[0003] For example, publication number CN108820289A discloses a vertical wire-hooking baling machine and its working method, including a baling machine body, a compression chamber, a wire-hooking and twisting box, a hopper, and a hydraulic station. The baling machine body has a compression chamber with a pusher inside. Above the compression chamber are the wire-hooking and twisting box and the hopper. A hydraulic station is located at one end of the baling machine body. The wire-hooking and twisting box contains multiple vertically installed wire-hooking rods, each consisting of a wire-hooking guide rod and a wire-hooking head. One side of each wire-hooking rod has a wire-cutting mechanism, and the other side has a wire-twisting mechanism. The above patent is an earlier application of this applicant. During the use of this technology, it was discovered that the wire often fails to be fed into the cutting opening, resulting in the wire not being cut and ultimately a poor pass rate for inverted bundling. Utility Model Content

[0004] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a wire binding mechanism for a baling machine and its auger.

[0005] According to the present invention, a auger for a wire binding mechanism of a baling machine includes a column, a auger plate located at the bottom of the column, the auger plate being an arc-shaped structural plate, a spiral blade located on the side of the column, the lower end face of the spiral blade being connected to the upper surface of the auger plate, and the spiral blade having a cross-section whose cross-sectional area gradually increases from the bottom to the top of the column.

[0006] In some embodiments, the spiral blades and the hinge plate have the same curvature.

[0007] In some embodiments, the hinge plate and the side of the column form a stop opening, and the spiral blade and the side of the column form an inner cavity, the inner cavity being located at the rear end of the stop opening.

[0008] In some embodiments, a baffle is provided at the top of the column. The baffle is a circular plate, and the baffle is concentrically arranged with the column, and the outer diameter of the baffle is larger than the diameter of the column.

[0009] In some embodiments, the column is an open-top cylindrical structure.

[0010] This utility model also provides a wire binding mechanism for a baling machine, which uses the aforementioned auger for the wire binding mechanism of the baling machine.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The wire bundling mechanism of this utility model uses a auger, which transforms a comma-shaped flat structure into a cylindrical structure with spiral blades, allowing the wire to move upward and outward. This enables the hooked wire to smoothly enter the shearing opening, ensuring that the bundled wire is cut smoothly. This solves the technical problem in the prior art where the wire cannot enter the shearing opening and thus cannot be bundled, effectively improving production efficiency.

[0017] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0018] This embodiment provides a auger for the wire binding structure of a baling machine, such as... Figure 1-2As shown, the device includes a cylindrical column 1, which in this embodiment is a cylindrical structure with open ends. A auger 2 is connected to the bottom of the column 1. The auger 2 is an arc-shaped structural plate, which in this embodiment is a crescent-shaped structural plate, which saves material while achieving winding and improves the structural compactness of the auger. In this embodiment, the auger 2 is integrally formed on the column 1, and its lower surface is flush with the bottom surface of the column 1. A spiral blade 3 is provided on the side of the column 1. The spiral blade 3 has a cross-sectional area that gradually increases from the bottom to the top of the column 1. The side of the spiral blade 3 with the larger cross-sectional area is connected to the side of the column 1, and the lower end face of the spiral blade 3 is connected to the auger 2. The inner cavity 31 formed at the connection between the spiral blade 3 and the side of the column 1 is located at the rear end of the stop 21 formed at the connection between the auger 2 and the side of the column 1. Here, the rear end refers to the direction along the circumferential direction where the cross-sectional area of ​​the spiral blade 3 gradually increases. In this embodiment, both the spiral blade 3 and the twisting plate 2 are arc plates with the same curvature. This facilitates the assembly of the spiral blade 3 and allows the wire wound into the twisting plate 2 to contact the edge of the inclined spiral blade 3 in a timely manner and be guided. In some embodiments, a baffle 4 is provided at the top of the column 1. The baffle 4 is a circular plate, concentrically arranged with the column 1, and the diameter of the baffle 4 is larger than the diameter of the column 1. With this structural design, when the baffle 4 has a portion extending outside the column 1, when the wire is twisted, it is not only guided upward by the spiral blade 3, but also guided outward by the outer edge of the baffle 4, thereby increasing the height at which the wire is lifted upward and further improving the accuracy of the wire entering the shearing cut.

[0019] The wire binding mechanism of the baling machine provided in this embodiment uses a cutting tool, the installation and use of which are as follows: Figure 3 As shown, a shearing opening and a wire hooking mechanism are located between two augers. When the wire hooking mechanism hooks up multiple strands of wire and forms an inverted V-shape, the augers on both sides rotate and twist the multiple strands of wire a certain number of turns. When the multiple strands of wire are twisted into a braided structure, the comma-shaped flat structure is transformed into a columnar structure with spiral blades, allowing the wire to move upward and outward. This enables the hooked wire to smoothly enter the shearing opening, ensuring that the bundled wire is cut smoothly. This solves the technical problem in the prior art where the wire cannot enter the shearing opening and thus cannot be bundled, effectively improving production efficiency.
