Automatic laminating machine for certificates and cards

Abstract

The invention discloses an automatic laminating machine for certificates and cards. The automatic laminating machine comprises a rack, wherein an automatic feeding device is mounted at one end of the rack, and at least two groups of pressing heads are mounted on the rack; each group of pressing heads comprise an upper pressing head and a lower pressing head which can be in press-fit, the lower pressing head is a movable pressing head and mounted on a movable plate, and the movable plate is matched with guide columns on the rack through sliding sleeves. With the adoption of the automatic laminating machine, the feeding device can realize continuous and circulating feeding, the working efficiency of the laminating machine is substantially improved, the height and the gravity center of the laminating machine can be effectively reduced, the stability is improved, no counter weight is required, the cost is low, hydraulic cylinders are located below the hot pressing heads and are far away from the thermal radiation range of the hot pressing heads, so that the hydraulic cylinders are prevented from working in a high-temperature environment, the service life of the machine can be substantially prolonged, and the like.

Description

technical field [0001] The invention relates to a laminating machine, in particular to an automatic card laminating machine. Background technique [0002] At present, most of the existing lamination equipment for printed matter such as cards and certificates uses devices such as negative pressure suction cups or grippers to send the raw materials to be pressed between the indenters, and after the pressing is completed, the finished products are taken out and sent to the next process. Then take new raw materials, the time interval between the work of the pressure head in this feeding method is longer, and the work efficiency is lower. In order to improve production efficiency, those skilled in the art have proposed a laminator equipment that uses a conveyor belt to circulate materials, and the raw materials to be pressed are sent between the press heads through the conveyor belt. The conveyor belt needs to be hot-pressed together with the material, resulting in a very limite...

AI Technical Summary

Problems solved by technology

In order to improve production efficiency, those skilled in the art have proposed a laminator equipment that uses a conveyor belt to circulate materials, and the raw materials to be pressed are sent between the press heads through the conveyor belt. The conveyor belt needs to be hot-pressed together with the material, resulting in a very limited service life of the conveyor belt, requiring frequent shutdowns for replacement, and the material often sticks to the conveyor belt after hot-pressing, resulting in a high failure rate and defective product rate

In addition, the current existing laminator equipment uses pneumatic cylinders or hydraulic cylinders to drive hot or cold pressure heads for pressing and bonding to realize hot pressing or cooling of multi-layer materials. The cylinders are all installed above the indenter, and the movable indenter is driven to press the fixed indenter from top to bottom. In order to match the feeding system, the pressing position of the indenter needs to maintain a certain height, so the lamination of the downward press The height of the machine itself is high, and the center of gravity is at the top, so the stability is poor. It is necessary to set a counterweight at the bottom. The high-temperature gas around the hot head always flows upwards, so the pneumatic cylinder or hydraulic cylinder always works in a high-temperature environment, and the service life will be severely affected
