Description

Technical Field

[0001] This utility model relates to a baling machine, belonging to the technical field of waste metal compaction and baling equipment. Background Technology

[0002] Existing horizontal scrap balers mainly consist of a hopper, a cover plate (also known as a door cover), a primary pressure cylinder (also known as a side cylinder), and a final pressure cylinder (also known as a main cylinder). After the scrap material is placed in the hopper, the cover plate, driven by the cover plate cylinder, covers the hopper. The primary pressure cylinder drives the primary pressure pusher to compress the scrap. Then, while keeping the primary pressure pusher stationary, the final pressure cylinder drives the final pressure pusher to compress the scrap, pressing it into a cuboid shape, thus completing the baling. This type of horizontal scrap baler can be found in patent documents with publication numbers CN219968938U, CN202088500U, and CN207842133U. These existing balers typically have only one primary pressure pusher, and either one (only one final pressure pusher is located on one side of the hopper) or two (one final pressure pusher is located on each side of the hopper). The pressing direction of the primary pressure pusher is perpendicular to the pressing direction of the final pressure pusher.

[0003] In the field of baling machine technology, there are two main ways to install hydraulic cylinders. One is swing-type installation, such as cover plate hydraulic cylinders. Usually, ear plates are set on the cover plate hydraulic cylinder, and the ear plates are rotatably connected to the pin shaft to realize the swing of the cover plate hydraulic cylinder. The other is fixed installation, such as initial pressure hydraulic cylinders and final pressure hydraulic cylinders. Flanges are fixedly set on the cylinder barrel. The flanges have through mounting holes. Fixing bolts pass through the mounting holes of the flanges from the outside and are threadedly connected and fixed to the baling machine housing (hydraulic cylinder mounting seat), such as Chinese utility model patents with publication numbers CN208578798U and CN208578784U.

[0004] A prior patent (publication number CN221819580U) discloses a novel baling machine with multiple final pressure cylinders on one side, in which a single final pressure pusher is simultaneously driven by multiple final pressure cylinders. During the development of this new baling machine, it was found that the shorter the distance from the center of each final pressure cylinder to the center of the final pressure pusher, the better; that is, the smaller the spacing between adjacent cylinders, the better, resulting in a more compact structure and better force distribution on the final pressure pusher. However, since each final pressure cylinder is fixed to the cylinder mounting base via a flange, the minimum spacing between adjacent final pressure cylinders is entirely determined by the flange diameter. To ensure the reliability of the final pressure cylinder installation, the flange diameter and thickness must be maintained above a certain size. Therefore, it is difficult to reduce the installation spacing between adjacent final pressure cylinders to an ideal state. Utility Model Content

[0005] In order to overcome the problems existing in the prior art, this utility model provides a baling machine that facilitates the compact installation of the final pressure cylinder. The specific technical solution is as follows.

[0006] A baling machine includes a material box, a final pressure pusher, and a final pressure cylinder, wherein the final pressure pusher is connected to the cylinder rods of a plurality of final pressure cylinders (i.e., a single final pressure pusher is driven by a plurality of final pressure cylinders), and the final pressure cylinders are mounted on the material box.

[0007] The cylinder of the final pressure cylinder has several bolt holes at its end. The opening of the bolt holes is located on the end face of the cylinder, and the end is located at the protruding end of the cylinder rod of the final pressure cylinder.

[0008] The material box has a cylinder mounting base, which has several mounting through holes. Several bolts pass through the mounting through holes and are threadedly connected to the bolt holes at the end of the cylinder of the final pressure cylinder.

[0009] Preferably, the cylinder barrel has a rod extension end and a non-rod extension end, and the outer diameter of the rod extension end is larger than the outer diameter of the non-rod extension end. Normally, the inner diameter of the cylinder barrel remains constant along its length. By thickening the rod extension end, the structural strength of the rod extension end is improved, thus enhancing the reliability of the cylinder barrel's installation and fixation.

[0010] Preferably, the cylinder is manufactured as a single piece. Single-piece manufacturing helps improve the stability and reliability of the cylinder. Single-piece manufacturing means that the cylinder is not assembled by welding two parts together, but is usually forged (or cast or extruded) as a single piece and then machined.

[0011] Preferably, the bolt holes are evenly distributed along the circumference of the cylinder.

[0012] Preferably, the bolt hole is a blind hole. Blind holes help improve the structural strength of the cylinder rod extension end of the cylinder barrel.

[0013] Preferably, the final pressure pusher is connected to the cylinder rods of four or five final pressure cylinders. When a single final pressure pusher is connected to four or five final pressure cylinders, the final pressure cylinders with the above-described structure can not only meet the cylinder installation space requirements well, but also transmit force to the final pressure pusher more reliably.

[0014] Compared with the prior art, this invention can minimize the installation distance between adjacent hydraulic cylinders, which is beneficial for adapting to situations where the installation space of hydraulic cylinders is limited, and also improves the force situation of the final pressure push head.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] See Figures 1-4 A baling machine includes a material box 1, a final pressure push head 2 and a final pressure cylinder 3, wherein a single final pressure push head 2 is connected to the cylinder rod 3.1 of four final pressure cylinders 3, and the final pressure cylinders 3 are installed in the material box 1;

[0022] Among them, such as Figures 2-3 As shown, the final pressure cylinder 3 includes a cylinder rod 3.1 and a cylinder barrel 3.2. The end of the cylinder barrel 3.2 of the final pressure cylinder 3 (the cylinder rod extension end A) is provided with a plurality of bolt holes 3.3. The opening of the bolt holes 3.3 is located on the end face of the cylinder barrel 3.2, and this end is the cylinder rod extension end A of the final pressure cylinder 3. Preferably, the plurality of bolt holes 3.3 are evenly distributed along the circumference of the cylinder barrel 3.2.

[0023] like Figure 4 As shown, the material box 1 has a cylinder mounting base 1.1, which has several mounting through holes 1.2. Several bolts 4 pass through the mounting through holes 1.2 and are threaded into the bolt holes 3.3. The cylinder mounting base 1.1 can be part of the material box 1 or a separate component fixed to the material box 1. The cylinder mounting base 1.1 is used to mount the final pressure cylinder 3, and its structural form can be determined according to specific circumstances. It is usually a plate component.

[0024] In a preferred embodiment, the cylinder 3.2 has a rod extension end A and a non-rod extension end B, with the outer diameter of the rod extension end A being larger than the outer diameter of the non-rod extension end B. Typically, the inner diameter of the cylinder 3.2 remains constant along its length. Thickening the rod extension end A of the cylinder 3.2 improves its structural strength and enhances the reliability of its installation and fixation. Note that the non-rod extension end B of the cylinder 3.2 does not refer to the end cap 3.4 of the final pressure cylinder 3, but rather to one end of the cylinder 3.2.

[0025] Preferably, the cylinder barrel 3.2 is manufactured as a single piece. Single-piece manufacturing helps improve the stability and reliability of the cylinder barrel 3.2. Single-piece manufacturing means that the cylinder barrel 3.2 is not assembled by welding two parts, but is usually formed by single-piece forging (or single-piece casting or single-piece extrusion) followed by machining. The bolt hole 3.3 is preferably a blind hole. Being a blind hole helps improve the structural strength of the cylinder rod extension end A of the cylinder barrel 3.2.

[0026] It should be noted that the number of final pressure cylinders 3 connected to a single final pressure pusher 2 is multiple, preferably four or five. When a single final pressure pusher 2 is connected to four or five final pressure cylinders 3, the final pressure cylinders 3 with the above-described structure can not only meet the cylinder installation space requirements well, but also transmit force to the final pressure pusher 2 more reliably.

[0027] The installation method of the final pressure cylinder 3 in this embodiment is different from the traditional installation method of cylinders with flanges. When installing a cylinder with a flange, the bolt 4 passes through the flange (not shown) and is threaded to the cylinder mounting seat 1.1. That is, the installation direction of the bolt 4 is from the outside to the inside of the baling machine, and the bolt 4 is usually visible from the outside of the baling machine. When installing the final pressure cylinder 3 in this embodiment, the bolt 4 passes through the cylinder mounting seat 1.1 and is threaded to the bolt hole 3.3 of the cylinder barrel 3.2. That is, the installation direction of the bolt 4 is from the inside to the outside of the baling machine, and the bolt 4 is usually not visible from the outside of the baling machine.

[0028] The embodiments of the present invention have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features described herein can be combined with each other. The present invention is not limited to the specific embodiments described above; these embodiments are merely illustrative and not limiting. Those skilled in the art, under the guidance of the present invention, can make many modifications without departing from the spirit and scope of the claims, and all such modifications fall within the protection scope of the present invention.
