Description

An automatic packaging machine

technical field

The utility model relates to the technical field of packaging equipment, in particular to an automatic packaging machine.

Background technique

Most of the finished product packaging of domestic small and medium-sized chemical fertilizer factories is packaged by manual weighing and packaging. The labor intensity is high and the measurement accuracy is low. The production efficiency of the enterprise is greatly reduced, and the finished products of small and medium-sized chemical fertilizer plants are mostly powdery materials that are easy to agglomerate and have poor fluidity. Therefore, it is necessary to design an automatic fertilizer packaging equipment suitable for small and medium-sized chemical fertilizer plants.

Utility model content

In order to solve the above problems, the utility model provides an automatic packaging machine, which has a simple structure, small size, low cost, high measurement accuracy, strong practicability, and greatly improves the production efficiency of the enterprise.

In order to achieve the above purpose, the technical solution adopted by the utility model is: an automatic packaging machine, including a powder silo, a first motor, a second motor, a thick screw, a thin screw, a feeding port, a middle feeding door, and a hopper , valve, bagging mechanism, knife holder, weighing flower, buffer cylinder, the first proximity switch and the second proximity switch, the conveying device below the powder silo is equipped with a thick screw rod, a thin screw rod, a thick screw rod, and a thin screw rod The rods are respectively connected with the first motor and the second motor. The end of the conveying device is provided with a discharge port, below the discharge port is a middle material door, below the middle material door is a hopper, at the bottom of the hopper is a valve, and at the bottom of the valve is a device. Bag mechanism; there is a lever on one side of the middle material door, a tool holder under the middle of the lever, a scale flower under one side of the lever, a buffer cylinder above the lever, and a first proximity switch and a second proximity switch at the end of the lever; The first motor, the second motor, the bagging mechanism, the first proximity switch and the second proximity switch are all connected to a PLC controller.

Preferably, a conveying device is further arranged below the bagging mechanism.

As a preference, the bagging mechanism is provided with a bag clamping manipulator.

The utility model has the following beneficial effects: the weighing process of the lever and the thin lever changes from dynamic to quasi-static mode due to the adoption of thick and spiral section cutting, and the addition of advanced detection means improves the measurement accuracy.

detailed description

In order to make the purpose and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

As shown in Figure 1, the embodiment of the utility model provides an automatic packaging machine, including a powder bin 1, a first motor 2, a second motor 3, a thick screw 4, a thin screw 5, a feeding port 6, Middle material door 7, hopper 8, valve 9, bagging mechanism 10, knife rest 11, weighing flower 12, buffer cylinder 13, first proximity switch JK1 and second proximity switch JK2, set in the conveying device below powder bin 1 There are a thick screw 4 and a thin screw 5, the thick screw 4 and the thin screw 5 are respectively connected with the first motor 2 and the second motor 3, the end of the conveying device is provided with a feeding port 6, and the lower part of the feeding port 6 is set There is a middle material door 7, a hopper 8 is located below the middle material door 7, a valve 9 is arranged at the bottom of the hopper 8, and a bagging mechanism 10 is arranged at the bottom of the valve 9; a lever is arranged on one side of the middle material door 7, and a knife rest is arranged under the middle of the lever 11. A scale flower 12 is arranged under one side of the lever, a buffer cylinder 13 is arranged above the lever, and a first proximity switch JK1 and a second proximity switch JK2 are arranged at the end of the lever; the first motor 2, the second motor 3 and the bagging The mechanism 10, the first proximity switch JK1 and the second proximity switch JK2 are all connected to the PLC controller.

It should be noted that a conveying device is also provided below the bagging mechanism 10 .

In addition, the bagging mechanism 10 is provided with a bag clamping robot.

The working principle of this automatic packaging machine: When the weight of the material in the hopper reaches 90% of the bagged weight, the lever tilts to make the first proximity switch JK1 send a signal, the controller resets the buffer cylinder and turns off the first motor. The thin spiral continues to feed until it is full, the second proximity switch JK2 sends a signal, the middle material door moves to intercept a small amount of stagnant air, and the second motor is turned off. When the controller checks that the packaging bag has been clamped by the manipulator, it opens the hopper valve to remove the material. Put it into the bag, and the manipulator releases the material after blanking. The bag is dropped on the conveyor belt and sent to the subsequent sewing and transportation processes. At this time, the hopper valve is automatically closed, the middle material door is opened, and the second large motor starts to continue the next weighing, packaging and bag clamping action, and the manipulator clamps the bag after bagging.

The above is only a preferred embodiment of the utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the utility model, some improvements and modifications can also be made. These improvements and modifications It should also be regarded as the protection scope of the present utility model.
