Automatic-unloading opening sealing machine

Abstract

The invention discloses an automatic-unloading opening sealing machine and relates to the technical field of an electromechanical technology. A cylinder is mounted at the upper part of a frame and is connected with an upper pressing plate through a piston rod; an upper opening sealing plate is arranged at the lower surface of the upper pressing plate; an upper heating device is arranged inside the upper pressing plate and is connected with the upper opening sealing plate through a circuit; a lower opening sealing plate is arranged below the upper opening sealing plate; a lower pressing plate is arranged at the lower surface of the lower opening sealing plate; a lower heating device is arranged inside the lower pressing plate; the lower heating device is connected with the lower opening sealing plate through a circuit; the lower pressing plate is fixedly arranged on a rotary disc; an output shaft of a stepping motor is connected with a rotating shaft of the rotary disc; a PLC (Programmable Logic Controller) and a control panel are also arranged at the upper part of the frame; a coder is arranged on the stepping motor; the stepping motor and the coder are connected with the PLC; the PLC is connected with the control panel. The automatic-unloading opening sealing machine disclosed by the invention has the advantages of needing no manual operation, reducing the amount of labor of workers and solving the problem of high operating cost caused by use of a mechanical arm.

Description

technical field [0001] The invention relates to the field of electromechanical technology, in particular to an automatic unloading and sealing machine. Background technique [0002] The sealing machine is a machine that seals a container filled with packaging. After the product is loaded into the packaging container, in order to keep the product sealed and preserved, maintain product quality, and avoid product loss, it is necessary to seal the packaging container. This operation is in Finished on the sealer. To put it simply, a sealing machine refers to a machine that seals a container after it is filled with a product. There are many materials for making packaging containers, such as paper, plastic, glass, ceramics, metals, composite materials, etc., and the shapes and physical properties of packaging containers are also different. Therefore, the sealing forms and sealing devices used are also different. [0003] At present, there are manual sealing machines, semi-automat...

AI Technical Summary

Problems solved by technology

[0003] At present, there are manual sealing machines, semi-automatic sealing machines and automatic sealing machines on the market; manual sealing machines are labor-intensive and inefficient, and cannot be used with automatic filling lines; semi-automatic sealing machines reduce labor intensity and are not efficient. The speed of the multi-head filling line is not high; while the automatic sealing machine is driven by an air cylinder, it is inconvenient to change and adjust containers of different heights and diameters; at present, the capping head adopts the sealing pliers of the manual sealing machine, and the lowering of the cap is completed by a cylinder, and the capping is positioned after falling After the plate contacts with the upper surface of the container, it is blocked and positioned. After the cylinder pressure overcomes the resistance, the capping arm bends the basket claws and buckles inwards to realize sealing. During the whole process of sealing, the container takes the bottom as the support point. If the conveying line does not stop during sealing, it will run The load is super strong, the power of the transmission motor is large, the surface of the transmission belt is prone to wear and tear, the workload of replacement and maintenance is large, and the cost of use and maintenance is high

If the conveying line is stopped during sealing, the wear on the surface of the transmission belt is relatively small, and it needs to be started frequently before and after sealing, the production capacity is not high, and the production capacity of multi-head filling is even lower, which requires multiple heads to achieve, and the total power consumption is large.

[0004] The unloading of the sealing machine in the prior art requires manual operation, and the labor load of the workers is large, or it is operated by a robot, and the cost is high
