Gravity Feeding Automatic Quantitative Double Scale Packaging Machine

technical field

The utility model belongs to the technical field of packaging machines, in particular to a gravity-feeding automatic quantitative double-scale packaging machine.

Background technique

With the development of science and technology and the continuous progress of society, electronic technology and computer technology have developed rapidly. Quantitative packaging machines have gone through several stages of relay control, weighing instrument control, and PLC control from the most primitive manual weighing, and gradually developed. Electronic automatic weighing. This enables the packaging industry to get rid of the problems of high labor intensity, slow packaging speed, harsh working environment, and serious pollution. At the same time, in the food and pharmaceutical industries, manual packaging often cannot meet hygienic requirements, and toxic and harmful chemicals are easy to cause harm to the human body. It has also been effectively improved. Today, quantitative packaging machines are widely used in daily necessities, food, medicine, building materials, agriculture, industry and other industries. It is of great significance to improve the automation level of packaging machinery and improve the packaging quality of products.

At present, there are three types of quantitative packaging machines for medium and large doses of powdery and granular materials: volumetric, weighing and mixing. The weighing type and the mixing type measure the quantity of materials by weight, and the quantitative accuracy is high, which can reach more than ±1.5%, but the quantitative speed varies widely, and it is difficult to coordinate with the packaging machine. The speed is difficult to meet the current high-volume high-precision quantitative packaging requirements. In order to effectively improve the packaging efficiency and meet the needs of the majority of users, the double-scale packaging machine is undoubtedly the first choice in the field of medium and large-dose packaging. It not only has the packaging quality and weighing accuracy of a single-scale packaging machine, but also has the unparalleled packaging speed of a single-scale packaging machine, which has become an inevitable trend in the development of packaging machines. However, the control system of the double-scale packaging machine is more complicated than that of the single-scale, and it is particularly important in the control of the feeding distribution and unloading sequence of the double-scale.

detailed description

The technical scheme of the utility model will be described in detail below in conjunction with the accompanying drawings and embodiments.

Example 1

Fig. 1 is the structure schematic diagram of the gravity-feeding automatic quantitative double-scale packing machine of the utility model.

In the embodiment, a gravity-fed automatic quantitative double-scale packaging machine includes a storage hopper 1, a feeding device, a weighing device and a clamping device 6; two material level switches are set in the storage hopper 1, and the material level switches are Vibrating rod type material level switch; a feeding device is set under the storage hopper 1, and the feeding device includes two feeding mechanisms on the left and right, which are A scale feeding mechanism 2 and B size feeding mechanism 8, and the feeding mechanism includes feeding mechanism Doors and associated cylinders;

Right below the feeding device is a weighing device. The weighing device includes a load cell 3, a weight display controller 4 and a discharge door, which are respectively A discharge door 5 and B discharge door 7. Below the weighing device is The clamping device 6; the clamping device 6 includes an entrainment mechanism and a proximity switch, and the proximity switch is a photoelectric proximity switch.

The structure of the entrainment mechanism is shown in Figure 2. The entrainment mechanism includes a cylinder 9, a connecting plate 11, a rotating shaft 12 and a discharge door 16; the cylinder 9 is connected to the connecting plate 11 through a joint 10, the connecting plate 11 is fixed on the rotating shaft 12, and the rotating shaft 12 is fixed on the bracket 13, below the rotating shaft 12 The blanking gate 16 is set in the middle position.

The feeding device can change the opening size of the feeding door by controlling the cylinder in the feeding stage, and then control the large and small two-stage feeding mode. During coarse feeding, the feeding gate is fully opened. When receiving a section of feeding completion signal from the weight display controller 4, the feeding gate is partially closed to realize fine feeding. When the predetermined amount is reached, the feeding gate is completely closed.

The main device of the weighing device is the weight display controller 4, which processes the weight data measured by the load cell 3 and sends it to the weight display controller 4. After the weighing is finished, the weighing display controller 4 will output a completion signal to control the unloading process. When a scale meets the discharge requirements, the output signal controls the discharge door to open. After the unloading is completed, when the conditions are met, the unloading door is closed.

The clamping device 6 is used to clamp the packaging bag so that the weighed materials can all fall into the packaging bag. During the bag clamping process, the worker first puts the packaging bag on the clamping device 6. After adjusting the position, he approaches the photoelectric proximity switch with his hand, and the clamping system receives a signal to clamp the bag. If the bag is not clamped, the bag can be released manually by pressing the button.
