Description

Technical Field

[0001] The present invention relates to the technical field of weighing and filling, and in particular to an automatic weighing and filling integrated machine and a filling method thereof. Background Art

[0002] In the early days, production and filling mainly relied on manual operation. Workers used simple tools such as funnels and spoons to fill materials into containers. This method was inefficient, and the filling accuracy depended entirely on the workers' experience and operating skills, with large errors. For example, in the food industry, when manually filling rice, it is easy to have inconsistent filling volumes, affecting product quality and market competitiveness.

[0003] With the continuous development of industrial production, enterprises have higher and higher requirements for production efficiency and product quality. In the filling process, the traditional manual filling method is not only inefficient, but also prone to human errors, and cannot meet the needs of large-scale production. With the advancement of the industrial revolution, mechanical filling equipment began to appear. These devices usually use piston-type, gravity-type and other principles for filling. The piston filling machine pushes the material out for filling through the reciprocating motion of the piston, while the gravity filling machine uses the gravity of the material itself to flow into the container. The filling equipment at this stage has improved production efficiency to a certain extent, but there are still some problems. For example, the degree of automation of the equipment is low, and a large number of manual auxiliary operations are required. Not only does it require cumbersome bag opening adjustment and fixing operations during filling, the bag hanging efficiency is low, and the adaptability and stability are poor, which is easy to cause spillage and bag dropping, and the weighing accuracy is low. During the metering process, due to the influence of the material flow rate, it often affects the weight measurement of the material during the filling process, resulting in weighing errors, affecting the filling accuracy, and making certain filling limitations.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Summary of the invention

[0041] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0042] According to the first embodiment of the present invention, an automatic weighing and filling machine is provided.

[0043] like Figure 1-Figure 6 As shown, the automatic weighing and filling integrated machine according to the embodiment of the present invention comprises: a frame 1 and a weighing bucket 2 arranged at the top of the frame 1, and a hanging plate 3 is arranged at the bottom of the frame 1 and the weighing bucket 2, wherein;

[0044] A weighing sensor 4 is provided in the measuring hopper 2, a weighing mechanism 5 for micro-adjustment is provided at the top input port of the measuring hopper 2, and a material discharge mechanism 6 is provided at the bottom output port of the measuring hopper 2;

[0045] A lifting mechanism 7 is provided between the hanging plate 3 and the frame 1 , and a material pipe 8 is provided inside the hanging plate 3 , the material pipe 8 is matched with the measuring bucket 2 , and a bag holding mechanism 9 is provided at the bottom end of the material pipe 8 .

[0046] A control panel 10 is provided on one side of the frame 1, and the control panel 10 is electrically connected to the weighing sensor 4, the rotating motor 56, the first telescopic cylinder 63 and the second telescopic motor 72 through wires.

[0047] In addition, the weighing mechanism 5 includes a hopper 51 provided at the top input port of the measuring hopper 2, a sealing plate 52 is slidably provided in the hopper 51, a measuring port 53 is provided on one side of the sealing plate 52, a push rod 54 is movably connected to the other side of the sealing plate 52, an arc plate 55 is movably connected to the end of the push rod 54, a rotating motor 56 is provided at the bottom end of the arc plate 55, and the rotating motor 56 is fixedly connected to the frame 1.

[0048] This technical solution controls the rotary motor 56 to drive the sealing plate 52 to slide outward, opens the hopper 51, and enters the unloading mode. The material flows into the measuring hopper 2 through the hopper 51, and the current weight in the measuring hopper 2 is obtained in real time through the weighing sensor 4. Specifically:

[0049] If the weight in the current measuring hopper 2 reaches the preset rough weight threshold, the rotary motor 56 is controlled to drive the sealing plate 52 to slide inward, reducing the material discharge rate of the hopper 51 and entering the fine-tuning mode. The material flows into the measuring hopper 2 through the measuring port 53, and the current weight in the measuring hopper 2 is obtained in real time through the weighing sensor 4.

[0050] If the weight in the current weighing hopper 2 reaches a preset precision weight threshold, the rotary motor 56 is controlled to drive the sealing plate 52 to continue sliding inward, closing the measuring port 53 and the hopper 51, thereby completing the automatic weighing of the material.

[0051] With the help of the above solution, by setting the multiple weighing methods of rough weight threshold and fine weight threshold, accurate filling control can minimize the waste of materials, avoid material overflow and loss caused by overfilling, and reduce the need for secondary filling due to insufficient filling.

[0056] In addition, the bag holding mechanism 9 includes a pressure ring 91 with an arc-shaped structure adapted to be arranged on one side of the bottom end of the material tube 8. One side of the pressure ring 91 is movably connected to the hanging plate 3 through a rotating shaft, and the other side of the pressure ring 91 is provided with a hook 92 and a caliper 93, and the hook 92 and the caliper 93 are adapted to each other.

[0057] Among them, a plurality of hooks 11 are respectively provided on one side of the hanging plate 3 .

It can be adjusted according to the size and shape of the bag to meet diverse packaging needs.

[0059] With the help of the above solution, the weight of the material can be measured in real time and accurately to ensure the accuracy of each filling. Even small weight differences can be keenly perceived, which greatly improves the consistency of the product. In addition, precise filling control can minimize material waste, avoid material overflow and loss caused by overfilling, and reduce the need for secondary filling due to insufficient filling. At the same time, it can achieve fast filling operations, greatly shorten the filling time, improve production efficiency, and can perform filling operations continuously without frequent shutdown adjustments to meet the needs of large-scale production.

[0060] According to the second embodiment of the present invention, a filling method of an automatic weighing and filling machine is provided.

[0062] Put the bag on the bottom of the material tube 8 in advance and lock it by pressing the pressure ring 91, the hook 92 and the caliper 93;

[0063] Control the second telescopic motor 72 to drive the hanging plate 3 to adjust in the vertical direction, and limit the docking position of the material pipe 8 and the output port at the bottom of the metering bucket 2;

The material flows into the measuring hopper 2 through the measuring port 53, and the current weight in the measuring hopper 2 is obtained in real time through the weighing sensor 4.

[0066] If the weight in the current weighing hopper 2 reaches the preset precision weight threshold, the rotary motor 56 is controlled to drive the sealing plate 52 to continue sliding inward, closing the measuring port 53 and the hopper 51, completing the automatic weighing of the material;

[0067] The first telescopic cylinder 63 is controlled to drive the rotating block 62 to link the fan blade 61 to open. At this time, the material in the measuring bucket 2 flows to the material pipe 8 through the bottom output port and flows into the bag, completing the automatic weighing and filling of the material.

[0068] It should be noted that the present invention can be configured with an automatic production line, realizing a fully automated process from material transportation, weighing, filling to packaging, reducing manual intervention and labor intensity. Operators only need to perform simple monitoring and management to complete the entire production process. The automated process improves the stability and reliability of production, reduces production interruptions and quality problems caused by human operational errors, and meets the market demand for automated industrial production.
