Packaging equipment includes machinery and equipment for processes such as the manufacture of synthetic packaging materials, printing, and container forming, and is a machine that converts raw materials through processing, printing, etc. into packaging containers. Most of the crossbeams of existing four-column mechanical equipment are of fixed structures, and the cross-sectional areas of the crossbeams are small, making it inconvenient for staff to operate;

[0003] According to Chinese Patent No. CN213271862U, a precision four-column beam structure is provided, including a hydraulic precision four-column telescopic rod main body. There are four of the hydraulic precision four-column telescopic rod main bodies. Below each of the four hydraulic precision four-column telescopic rod main bodies, there is a precision four-column fixed rod main body, and one end of the precision four-column fixed rod main body penetrates and extends into the interior of the hydraulic precision four-column telescopic rod main body. On one side of the precision four-column fixed rod main body, there is a hydraulic pipeline, and there are four hydraulic pipelines. One end of each of the four hydraulic pipelines penetrates and extends into the interior of the precision four-column fixed rod main body.

Specific implementation manner:

[0016] The following combines the drawings and specific embodiments to further describe the present utility model, so as to more clearly understand the technical idea claimed by the present utility model.

[0017] As Figures 1 to 3 shown, a new type of mechanical crossbeam structure includes a beam body 1, support columns 2 and a lifting support device. Two extension plates 3 are slidably connected to the front and rear sides of the beam body 1. Four support columns 2 are correspondingly arranged at the four vertex positions of the bottom surface of the beam body 1. Four lifting support devices are correspondingly arranged on the four support columns 2. The lifting support device includes a lifting cylinder 4, a first support rod 5 and a second support rod 6. The lifting cylinder 4 is fixed on the front side of the support column 2, and the output end of the lifting cylinder 4 is hinged to the first support rod 5. The second support rod 6 is hinged to the front side of the support column 2, and the second support rod 6 is hinged to the first support rod 5.

[0018] The working principle of the new type of mechanical crossbeam structure of the present utility model is realized by the mutual cooperation of the lifting cylinder 4, the first support rod 5 and the second support rod 6. As Figures 1 to 3 shown, when the extension plate 3 extends out from the beam body 1, then the output end of the lifting cylinder 4 extends upward and drives the first support rod 5 to swing away from the support column 2. The second support rod 6 swings outward with the first support rod 5 and makes the first support rod 5 expand. And the first support rod 5 abuts against the bottom surface of the extension plate 3 and supports the extension plate 3. When the extension plate 3 is accommodated in the beam body 1, the output end of the lifting cylinder 4 contracts downward and drives the first support rod 5 to swing towards the support column 2. The second support rod 6 swings inward with the first support rod 5 and makes the first support rod 5 contract, thereby reducing the overall occupied space. Compared with the traditional mechanical crossbeam, the lifting cylinder 4 of the new type of mechanical crossbeam structure can drive the first support rod 5 and the second support rod 6 to swing, so that the first support rod 5 abuts against the extension plate 3 and cooperates with the second support rod 6 and the lifting cylinder 4 to support the extension plate 3, so as to prevent one side of the extension plate 3 from being pressed and tilted or even damaged.

[0019] Specifically, the front and rear sides of the beam body 1 are provided with slide grooves (not shown in the figure), and the two extension plates 3 are slidably connected to the two slide grooves of the beam body 1. The novel mechanical crossbeam structure described in the utility model also includes four telescopic cylinders 7, two of the telescopic cylinders 7 are arranged on the left side of the beam body 1 with their backs facing each other, and the output ends of the two telescopic cylinders 7 are connected to the two extension plates 3 with their backs facing each other, and the other two telescopic cylinders 7 are arranged on the right side of the beam body 1 with their backs facing each other, and the output ends of the other two telescopic cylinders 7 are connected to the two extension plates 3 with their backs facing each other. Figures 1 to 3 As shown, the output end of the telescopic cylinder 7 is connected to the extension plate 3 through a linkage plate. The output end of the telescopic cylinder 7 extends out and drives the extension plate 3 to extend out from the slide slot of the beam body 1, which can automatically push and pull the extension plate 3 instead of the staff and is easy to use.

[0020] Further, a hydraulic telescopic rod 8 is provided on the bottom surface of the pillar 2, and a hydraulic pipeline is provided on the hydraulic telescopic rod 8, wherein a mounting groove 9 is provided on the top surface of the pillar 2, and a through hole 10 is provided on the side wall of the pillar 2, and four mounting blocks 11 are provided on the bottom surface of the beam body 1, and the mounting blocks 11 are provided with threaded holes 12, and the four mounting blocks 11 of the beam body 1 are correspondingly plugged into the mounting grooves 9 of the four pillars 2, and the through holes 10 of the pillar 2 and the threaded holes 12 of the mounting blocks 11 are connected by bolts, as shown in FIG. Figures 1 to 3 As shown, the height of the support 2 can be adjusted by a hydraulic telescopic rod 8, and the mounting block 11 of the beam body 1 and the mounting groove 9 of the support 2 are detachably connected by bolts, which is convenient for disassembly and assembly and improves the stability of the connection between the beam body 1 and the support 2.

[0021] Furthermore, the output end of the lifting cylinder 4 is hinged to one end of the first support rod 5 through a hinge seat, one end of the second support rod 6 is hinged to the front side of the pillar 2, and the other end of the second support rod 6 is hinged to the middle of the first support rod 5, such as Figures 1 to 3 As shown, the output end of the lifting cylinder 4 extends outward to drive the upper end of the first support rod 5 to swing outward, and the lower end of the second support rod 6 to swing outward. The first support rod 5 and the second support rod 6 are spread apart and the first support rod 5 is pressed against the bottom surface of the extension plate 3 to assist the beam body 1 in supporting the extension plate 3 to prevent the extension plate 3 from being subjected to excessive pressure toward one side of the beam body 1, causing the extension plate 3 to tilt as a whole or even damage the extension plate 3.

[0022] The above are only specific embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
