[0002] Currently, during the packaging process, a tray is needed to support the bottom of the bag. Most existing support methods use a pallet, which has a problem: the height of the pallet is difficult to adjust. If adjustment is needed, a shim needs to be placed under the pallet, which is a cumbersome process. Therefore, this solution was developed. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a load-bearing structure for a packing machine, which realizes the adjustment of the distance between the adjustment frame and the base through the adjustment rod, thereby realizing the height adjustment of the pallet.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a load-bearing structure for a baling machine, including a base, a tray, a column, and an adjusting frame. The column is set on the base, and the adjusting frame has a sliding hole. Pulleys are formed on both sides of the sliding hole. The column is located in the sliding hole, and the two pulleys are respectively attached to the two sides of the column. The adjusting frame is fixedly connected to the tray through a connecting plate. An adjusting rod is provided between the adjusting frame and the base.

[0005] Furthermore, the adjusting frame includes two I-beams, which are spaced apart. Each I-beam includes two horizontal plates and one vertical plate. The number of pulleys is four, which are located at the ends of the two horizontal plates and between the two I-beams.

[0006] Furthermore, a fixing post is provided between either side of the two lower horizontal plates, and a threaded hole is formed on the fixing post. An external thread is formed on the circumferential surface of the adjusting rod, and the adjusting rod passes through the threaded hole and its lower end abuts against the base.

[0007] Furthermore, the load-bearing structure also includes two oscillating cylinders, which are disposed below the tray and whose output ends are connected to the lower surface of the tray. The adjustable frame is connected to the cylinder surface of any one of the oscillating cylinders via a connecting plate.

[0008] Furthermore, the lower surface of the tray is provided with two spaced-apart extension plates, one of which is provided with a connecting shaft at the output end of the oscillating cylinder. The two extension plates are connected to both sides of the connecting shaft through a first plate, and the first plate is rotatably connected to the end face of the connecting shaft.

[0009] Furthermore, two spaced protrusions are formed on the lower surface of the tray, and a strip plate is provided at the output end of the other oscillating cylinder. Hinges are formed on both sides of the upper surface of the strip plate, and hinge notches are formed on the upper surface of the hinges. The protrusions extend into the hinge notches and are hinged to the hinges.

[0010] Furthermore, an adapter plate is provided on the upper surface of any of the aforementioned oscillating cylinders, and the adapter plate and the connecting plate are connected by a connector.

[0011] Furthermore, an inclined plate is formed on the upper surface of the tray near the column.

[0012] Furthermore, the load-bearing structure also includes a hook bag assembly, which includes an ejector cylinder, a mounting frame, a drive body, and an L-shaped rotating plate. The ejector cylinder is disposed on the upper surface of the column, and its output end is fixedly connected to the mounting frame. There are two drive bodies disposed inside the mounting frame, with the two drive bodies located on opposite sides of the mounting frame and their output ends extending out of the upper surface of the mounting frame. One end of the L-shaped rotating plate is fixedly connected to the output end of the drive body, and the drive body drives the L-shaped rotating plate to rotate.

[0013] Furthermore, the ejector cylinder and the mounting bracket are connected by a second plate, the second plate is connected to the mounting bracket, the output end of the ejector cylinder is connected to the second plate, a guide post is formed on the second plate, and a through guide hole is provided around the ejector cylinder, with the guide post located in the guide hole.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model involves placing a tray on the side of an adjustable frame, which is then adjusted via an adjustable rod and a base. By adjusting the adjustable rod, the relative height between the adjustable frame and the base can be adjusted, thereby achieving tray height adjustment. Furthermore, because a column is provided in the middle of the adjustable frame, when the tray is under load, the adjustable frame will tilt due to one side being heavier than the other. This causes the adjustable frame to lock onto the column, distributing most of the load on the adjustable rod.

[0015] 2. This solution also includes two vibrating cylinders, which are located below the tray. Each vibrating cylinder is connected to the adjusting frame via a connecting plate. The tray is indirectly connected to the adjusting frame. The two vibrating cylinders intermittently extend and retract, causing the tray to vibrate up and down. When the bag is receiving material, it can be vibrated to prevent the material inside the bag from becoming airtight. Attached Figure Description

Each I-beam 41 includes two horizontal plates and one vertical plate. There are four pulleys 42, which are located at the ends of the two horizontal plates and between the two I-beams 41. The four pulleys 42 are respectively attached to the sides of the upright column 3.

[0021] A fixing post 43 is provided between either side of the two horizontal plates located below. A threaded hole is formed on the fixing post 43. An external thread is formed on the circumference of the adjusting rod 44. The adjusting rod 44 passes through the threaded hole and its lower end abuts against the upper surface of the base 1. After the adjustment is completed, nuts need to be installed above and below the threaded hole to lock it.

[0022] Adjustment principle: Loosen the nuts on the upper and lower sides of the adjusting rod 44, rotate the adjusting rod 44, and the adjusting frame 4 will move up or down, thereby moving the pallet 2 up and down. After it moves into place, tighten the nuts on the upper and lower sides of the adjusting rod 44 to complete the adjustment. When the pallet 2 is under load, the adjusting frame 4 will tilt if one side is heavier than the other, thus causing the adjusting frame 4 to lock onto the column 3 and share most of the load of the adjusting rod 44.

[0023] The tray 2 is located on one side of the adjustable frame 4. An inclined plate 21 is formed on the upper surface of the tray 2 near the column 3.

The protrusions 23 extend into the hinge notch and are hinged with the hinge seat 53.

[0025] Vibration principle: Two vibrating cylinders 5, one extending and the other retracting, move back and forth to realize the up and down vibration of the tray 2, thereby realizing the vibration of the material in the bag during the filling process.

[0026] The hook bag assembly 6 includes an ejector cylinder 61, a mounting frame 62, a drive body 63, and an L-shaped rotating plate 64. The ejector cylinder 61 is located on the upper surface of the column 3 and can be a pneumatic cylinder, hydraulic cylinder, or electric cylinder. The output end of the ejector cylinder 61 is fixedly connected to the mounting frame 62. There are two drive bodies 63, which are located inside the mounting frame 62. The drive bodies 63 are drive motors. The two drive bodies 63 are located on both sides of the mounting frame 62, and their output ends extend out of the upper surface of the mounting frame 62. One end of the L-shaped rotating plate 64 is fixedly connected to the output end of the drive body 63, and the drive body 63 drives the L-shaped rotating plate 64 to rotate.

[0027] Specifically, the ejector cylinder 61 and the mounting bracket 62 are connected by a second plate. The second plate is connected to the mounting bracket 62. The output end of the ejector cylinder 61 is connected to the second plate. A guide post 65 is formed on the second plate. A through guide hole is provided around the ejector cylinder 61. The guide post 65 is located in the guide hole.

[0028] Hook bag principle: First, the ejector cylinder 61 ejects, so that the mounting bracket 62 fits against the surface of the bag. Then, the output end of the drive body 63 rotates, so that the L-shaped rotating plate 64 rotates from the outside to the inside, hooking the two sides of the bag.
