Description

Technical Field

[0001] This utility model relates to the field of baling machine technology, and in particular to a baling machine with a self-weighing function. Background Technology

[0002] Fully automatic packaging machines are widely used in industries such as food, pharmaceuticals, hardware, chemicals, clothing, and postal services. They are suitable for automatically packaging and bundling various sizes of goods, including cardboard boxes, paper, parcels and letters, medicine boxes, light industrial products, hardware tools, ceramic products, auto parts, daily necessities, stationery, and equipment. However, existing fully automatic packaging machines lack weighing capabilities. When packaging powdery materials, manual weighing is often required before feeding them into the machine, making the process cumbersome and inefficient.

[0003] In the prior art, Chinese patent application number 202320183415.1 discloses an automatic packaging machine with weighing function, including a base, a weighing mechanism, and a packaging mechanism. The weighing mechanism includes a first motor, a lead screw, a threaded block, a weighing platform, and a gravity sensor. This technical solution solves the problem in the prior art where, when packaging powdered materials, manual weighing is often required before feeding them into the packaging machine, resulting in a cumbersome packaging process and low efficiency. By setting up a weighing mechanism, the gravity sensor can detect the weight of the material being fed in real time. When the material reaches the designated weight, the first telescopic cylinder extends, inserting its telescopic end into the lifting seat and lifting the weighing platform. Then, the first motor drives the lead screw to rotate, moving the weighing platform to the packaging mechanism for packaging. This achieves simultaneous feeding, weighing, and packaging, simplifying the packaging process and improving efficiency.

[0004] However, the above-mentioned technical solutions have the problem that the weighing platform does not have a limiting mechanism. After the material is put into the packaging bag, it cannot be guaranteed to be stable when it is placed on the weighing platform and when it moves with the weighing platform. It is easy to tip over. Secondly, the continuity of the entire material packaging and weighing process is poor, which will affect the production efficiency. Therefore, this application proposes a packaging machine with self-weighing function to solve the above problems. Utility Model Content

Therefore, this invention proposes a packaging machine with a self-weighing function.

The interiors of the two mounting grooves are rotatably connected to second cylinders, and the output shafts of the second cylinders are rotatably connected to one side of the corresponding limit rods.

[0014] As a preferred embodiment of this utility model, the loading assembly includes two columns, two slide bars, a hopper, two third cylinders, and a discharge valve. The bottom ends of the two columns are fixedly installed on the top of the processing table. The hopper is located between the two columns. The two third cylinders are respectively fixedly installed on the side of the two columns that are close to each other. The output shafts of the two third cylinders are both engaged with the hopper.

The output shaft of the motor 2 passes through the processing table 1 and is fixedly installed at the bottom of the turntable 3.

[0036] To improve the limiting effect on the packaging bag, the second cylinder 11 is activated to drive the limiting rod 10 to rotate, so that the four corresponding limiting rods 10 can surround the packaging bag, thereby improving the limiting effect on the packaging bag. Both ends of the moving rod 8 are provided with mounting grooves 9, and the inner walls of the two mounting grooves 9 are rotatably connected to the limiting rods 10. The interior of the two mounting grooves 9 is rotatably connected to the second cylinder 11, and the output shaft of the second cylinder 11 is rotatably connected to one side of the corresponding limiting rod 10.

[0037] To enable the storage and quantitative discharge of powder materials, and thus cooperate with multiple weighing platforms for material bagging and weighing, the loading assembly includes two columns 12, two slide bars 13, a discharge hopper 14, two third cylinders 15, and a discharge valve 16. The bottom ends of the two columns 12 are fixedly installed on the top of the processing table 1. The discharge hopper 14 is located between the two columns 12.

Then, start the motor 2 to drive the turntable 3 and multiple weighing devices 4 to rotate and change positions, thereby enabling the multiple weighing devices 4 to be repositioned between the loading assembly and the packaging mechanism 20. When the weighing devices 4 rotate to a position corresponding to the loading assembly, the bag opening is placed over the four support rods 19. Then, start the fourth cylinder 17 to drive the four support rods 19 to move and open the bag opening. The bag is opened, and then the material is filled into the packaging bag through the discharge valve 16. After the filling is completed, the first cylinder 7 is activated to drive the two moving rods 8 to move, thereby clamping and limiting the packaging bag to ensure its stability after filling. At the same time, the second cylinder 11 is activated to drive the limiting rods 10 to rotate, so that the four corresponding limiting rods 10 surround the packaging bag, thereby improving the limiting effect of the packaging bag. In addition, the motor 2 drives the turntable 3 to rotate, which can realize the continuous filling, weighing and packaging of multiple packaging bags in sequence, improving production efficiency.
