Description

Technical Field

[0001] This utility model relates to the field of packaging machinery technology, and in particular to a weighing device for a packaging machine. Background Technology

[0002] A baler is a specialized piece of equipment that uses a hydraulic system or mechanical structure to compress loose materials. It is mainly used for volume reduction and transportation optimization of recycled materials such as waste metal, waste paper, and plastics.

[0003] Traditional baling machines often struggle to precisely control the weight of bales during the baling process, which can lead to uneven weight distribution and negatively impact subsequent transportation, storage, and processing. To address this issue, this invention proposes a weighing device for baling machines that achieves precise weight control by incorporating a weighing sensor and a cylinder control mechanism. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a weighing device for a baling machine. It can be placed directly on the baling machine to save space. By setting the weight independently, the weight of waste falling into the baling machine can be precisely controlled, thereby controlling the weight of the bales. This solves the technical problem in existing technologies where it is difficult to accurately control the weight of the bales, resulting in uneven bale weights and affecting subsequent transportation, storage, and processing.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a weighing device for a baling machine, comprising a mounting bracket, a weighing hopper mounted on the mounting bracket, a hopper plate opening and closing assembly mounted on the bottom of the weighing hopper, and weighing sensors mounted on the lower ends of the four corners of the mounting bracket. The hopper plate opening and closing assembly includes a pair of symmetrical guide rails mounted on the inner wall of the lower end of the weighing hopper, a hopper bottom plate slidably mounted on the two guide rails, and a pair of cylinders symmetrically mounted on the outer wall of the lower end of the weighing hopper. A connecting plate is mounted on the extended end of each cylinder, and the other end of the connecting plate is fixedly connected to the hopper bottom plate. The hopper bottom plate slides laterally back and forth on the guide rails due to the extension and retraction of the cylinders.

[0008] Furthermore, the mounting bracket includes four vertical beams, two of which are fixedly installed below the left end of the weighing hopper, and the other two are fixedly installed below the guide rail on the right side of the weighing hopper; a horizontal beam is fixedly connected between each pair of vertical beams.

[0009] Furthermore, the weighing hopper is a cuboid that runs vertically through the structure, with an inlet at the top and an openable bottom plate at the bottom.

[0010] Furthermore, the weighing device of the baling machine is mounted on the baling machine via the mounting bracket.

[0011] Furthermore, a controller is connected to the weighing sensor and the cylinder. When the waste material in the weighing hopper reaches a preset weight, the controller is used to stop feeding and control the cylinder to drive the bottom plate of the hopper to slide back and forth.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, the present invention provides a weighing device for a baling machine, which has the following advantages:

[0014] 1. The weighing device of this baling machine has a simple structure and is easy to operate. It can achieve precise control of the weight of the bale, which greatly improves the baling efficiency and quality.

[0015] 2. The weighing device of this baler can be placed directly on the baler to save space. It can accurately control the weight of the waste material falling into the baler by setting the weight independently, thereby controlling the weight of the bales. It adopts dual-cylinder control, which is stable and responsive. It can be linked with the baler and conveyor to achieve automated operation. It is suitable for various baling scenarios that require precise control of bale weight. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] Please see Figure 1-4 A weighing device for a baling machine includes a mounting bracket 1, on which a weighing hopper 2 is mounted. The mounting bracket 1 includes four vertical beams 101, two of which are fixedly mounted below the left end of the weighing hopper 2, and the other two are fixedly mounted below the guide rail 301 on the right side of the weighing hopper 2. A horizontal beam 102 is fixedly connected between each pair of vertical beams 101. A hopper plate opening and closing assembly 3 is installed at the bottom of the weighing hopper 2. Weighing sensors 4 are installed at the lower ends of the four bottom corners of the mounting bracket 1. The hopper plate opening and closing assembly 3 includes... A pair of symmetrical guide rails 301 are installed on the inner wall of the lower end of the weighing hopper 2. A hopper bottom plate 302 is slidably mounted on the two guide rails 301. A pair of cylinders 303 are symmetrically mounted on the outer wall of the lower end of the weighing hopper 2. A connecting plate 304 is installed on the extended end of the cylinder 303. The other end of the connecting plate 304 is fixedly connected to the hopper bottom plate 302. The hopper bottom plate 302 slides laterally back and forth on the guide rails 301 driven by the extension and retraction of the cylinders 303. The weighing hopper 2 is a vertically continuous cuboid, with a feed inlet 201 at the upper end and an openable hopper bottom plate 302 at the lower end. A controller is connected to the weighing sensor 4 and the cylinders 303. When the waste material in the weighing hopper 2 reaches the preset weight, the controller stops feeding and controls the cylinders 303 to slide the hopper bottom plate 302 back and forth.

[0023] In the above embodiment, the weighing device of the baling machine is mounted on the baling machine 5 via the mounting bracket 1.

[0024] The working principle of the above embodiments is as follows:

[0025] In use, the weighing device of the baler is installed on the baler 5 and placed below the discharge port of the conveyor. Waste material enters the weighing hopper 2 through the conveyor or other means. When the waste material enters the weighing hopper through the inlet 201 and reaches the preset weight, the control system controls the conveyor to stop feeding and controls the cylinder 303 to drive the bottom plate 302 of the hopper to slide outward on the guide rail 301 through the connecting plate 304, and the waste material falls into the baler 5. Then, the cylinder 303 drives the bottom plate 302 of the hopper to slide inward on the guide rail 301 to close, waiting for the next feeding action.
