Abstract
Description
Technical Field
[0001] The utility model relates to packaging equipment, in particular to a servo electric cylinder heat sealing device. Background Art
[0002] The heat sealing device is an important component of various packaging equipment. Its function is to heat-press two layers of packaging substrate together, thereby achieving thermal bonding of the packaging substrate. The heat sealing mechanism mainly includes an upper heat sealing plate and a lower heat sealing plate. When working, the upper and lower heat sealing plates are controlled to be close to each other to heat-press the packaging substrate together. At present, the defects of the heat sealing mechanism on the market are: 1. The movement of the heat sealing plate is generally driven by a cylinder. The pressure driven by the cylinder is limited. In actual use, it is easy to cause the heat pressing to be inadequate. At the same time, the movement stroke of the cylinder may change during long-term use, which will also affect the quality of the heat pressing; 2. For some specific packaging equipment, in order to leave space under the lower heat sealing plate, the lower heat sealing plate is fixed inside the equipment. In actual use, after the heat sealing process is completed, the upper heat sealing plate rises and separates from the packaging substrate, and the lower heat sealing plate may be partially bonded to the packaging substrate, affecting the normal traction and transportation of the product. Utility Model Content
[0003] In view of the shortcomings of the background technology, the technical problem to be solved by the utility model is to provide a servo electric cylinder heat sealing device for solving the above-mentioned problems.

[0008] A guide post is fixedly arranged on the base body, and a guide sleeve cooperating with the guide post is arranged on the lifting frame.
[0009] For a servo electric cylinder heat sealing device of the above technical solution, the electric cylinder is provided to drive the upper heating plate and the upper heat sealing plate to lift for heat sealing processing, replacing the traditional cylinder driving mode. The pressure driven by the electric cylinder is greater, which can ensure that the upper and lower heat sealing plates are tightly pressed for heat sealing processing. At the same time, during the long-term use process, the accuracy of the moving stroke of the upper heat sealing plate can be ensured, thereby ensuring the heat sealing quality. In addition, by arranging an air blowing hole structure on the lower heat sealing plate and the lower heating plate, high-pressure gas can be blown out from the air blowing holes after heat sealing to separate the packaging substrate from the lower heat sealing plate, thereby avoiding the packaging substrate from adhering to the lower heat sealing plate and ensuring that the traction operation of the substrate can be quickly carried out after heat sealing is completed.

[0014] As shown in the figure, a servo electric cylinder heat sealing device disclosed in the utility model includes a seat body 2, a servo electric cylinder 1 is installed on the top of the seat body 2, and the piston rod of the servo electric cylinder 1 is connected to the lifting frame 3. In this embodiment, the servo electric cylinder 1 is arranged in three groups, so that the lifting drive of the lifting frame 3 is more stable. A guide column 9 is fixedly arranged on the seat body 2, and a guide sleeve 8 cooperating with the guide column 9 is arranged on the lifting frame 3 to guide the lifting of the lifting frame 3. An upper heating plate 4 and an upper heat sealing plate 5 are arranged on the lifting frame 3, and a lower heat sealing plate 6 is arranged below the upper heat sealing plate 5. The lower heat sealing plate 6 is arranged on the top of the lower heating plate 7, and the lower heating plate 7 is fixed in the seat body 2. A first blowing hole 14 is opened through the lower heat sealing plate 6, and a second blowing hole 13 connected to the first blowing hole 14 is arranged on the lower heating plate 7. The second blowing hole 13 is connected to the air pump through an air pipe. Furthermore, the lifting frame 3 has a transmission rod 10 extending downward, the transmission rod 10 extends downward to the bottom of the lower heating plate 7, the bottom of the transmission rod 10 is connected to the lower lifting plate 11, and a push rod 12 is extended upward on the lower lifting plate 11. The lower heating plate 7 is provided with a first clearance hole 15 for the push rod 12 to pass through, and the lower heat sealing plate 6 is provided with a second clearance hole 16 for the push rod 12 to pass through. When the lifting frame 3 descends to the heat sealing height, the push rod 12 is not higher than the second clearance hole 16. When the lifting frame 3 rises and resets, the push rod 12 rises and passes through the second clearance hole 16.
[0015] The working principle of the utility model is as follows: the packaging substrate is pulled between the upper and lower heat-sealing plates, and then the servo electric cylinder 1 is controlled to drive the lifting seat 3 to descend, and then the upper heat-sealing plate 5 is driven to descend to press the packaging substrate tightly between the upper heat-sealing plate 5 and the lower heat-sealing plate 6 for heat-sealing processing. After the heat-sealing processing is completed, the servo electric cylinder 1 will drive the lifting seat 3 and the upper heat-sealing plate 5 to rise, so that the upper heat-sealing plate 5 is separated from the packaging substrate. At the same time, the air pump is started to pass high-pressure gas into the first and second blowing holes, and the packaging substrate is blown upward for a certain distance to separate it from the lower heat-sealing plate 6. At the same time, when the lifting seat 3 rises, it will drive the transmission rod 10 and the lower lifting plate 11 to rise, and then drive the push rod 12 to rise and pass through the second make way hole 16, and push the packaging substrate upward, which can also achieve the separation between the packaging substrate and the lower heat-sealing plate 6.
[0016] The structure of the utility model realizes heat sealing processing by arranging an electric cylinder to drive the upper heating plate and the upper heat sealing plate to rise and fall, thereby replacing the traditional cylinder driving method. The electric cylinder driving pressure is greater, which can ensure that the upper and lower heat sealing plates are pressed tightly for heat sealing processing. At the same time, the accuracy of the moving stroke of the upper heat sealing plate can be ensured during long-term use, thereby ensuring the heat sealing quality. In addition, by arranging a blowing hole structure on the lower heat sealing plate and the lower heating plate, high-pressure gas can be blown out from the blowing hole after the heat sealing is completed to separate the packaging substrate and the lower heat sealing plate, thereby avoiding the packaging substrate and the lower heat sealing plate from being adhered together, and ensuring that the substrate can be quickly pulled after the heat sealing is completed.
