Semi-automatic card pasting machine

Abstract

The invention provides a semi-automatic card pasting machine. The semi-automatic card pasting machine comprises a machine frame. A main composite roller arranged on the machine frame. A plurality of sets of auxiliary composite rollers disposed at intervals are arranged on the output side above the main composite roller. The main composite roller comprises a main fixed roller and a driving roller capable of adjusting the center distance along the horizontal direction of the main fixed roller. A main sliding groove is arranged in the machine frame. The two ends of the driving roller are providedwith main sliding blocks capable of sliding in the main sliding groove. An eccentric wheel abutting against the main sliding blocks is arranged between one side, towards the driving roller, of the main sliding block and the groove wall of the main sliding groove. A hydraulic jacking cylinder is arranged between one side, away from the driving roller, of the main sliding block and the other groovewall of the main sliding groove. A piston rod of the hydraulic jacking cylinder abuts against the main sliding block to enable the driving roller to be close to the main fixed roller and apply extrusion force. According to the semi-automatic card pasting machine, the overall flatness is high after composite grinding, the gap adjustment is convenient, the adjusting precision is high, and the composite grinding pressure is uniform; and the paper to be compounded can be transferred to the compounding waiting position when the paper is compounded, so that the overall work efficiency is improved,and the paper shortage waiting time is shortened.

[0002] The laminating machine is a kind of equipment used to bond two pieces of paper together. Its main structure includes a frame and two parallel rollers arranged on the frame. There is an upper rubber roller, and the paper is fed from both sides of the frame and fixed by the fixed claws on the rolling roller, and then brought between the two rolling rollers to achieve rolling and compounding. The paper after rolling is often Repeated rolling again. In the existing repeated rolling process, an auxiliary rolling roll is often installed above one of the rolling rolls. Therefore, during repeated rolling, the paper needs to be bent following the curvature of the outer wall of the rolling roll. In order to smoothly reach between the rolling roller and the auxiliary rolling roller, this makes it easy to cause paper bending during repeated rolling, which directly affects product quality. At the same time, the existing equipment generally uses screw adjustment to adjust the thickness of the paper. , or use springs to pre-compress and assist compounding to provide extrusion force for the rolling rollers, but the defect of the screw adjustment is that the gap between the rolling rollers is fixed immediately after adjustment, which means that the paper will be forcibly squeezed during compounding When the thickness is fixed, it is easy to cause damage to the paper. Although the spring-added adjustment device can provide a certain retreat when the paper is rolled in, the elasticity of each spring is often different, so it is easy to cause the rolling roller to be two. At the same time, the pressure applied at the end is deviated, and the pressure is difficult to reach the standard, which is prone to poor mounting and easy to affect product quality; at the same time, when rolling and compounding, the rotation speed of the two rolling rollers is the same, but the time point of paper feeding needs to pass through the equipment. Carry out effective control to avoid misalignment caused by the time difference between the two sheets of paper when they are combined together. At present, many laminating machines are semi-automatic paper feeding, and two people are required to put the single sheet of paper into the workbench. The workbench is conveyed to the rolling roller, sometimes the paper on one side has been put in, and the paper on the other side has not been put in, resulting in a difference in synchronization, so many laminating machines have stop gauges on the feeding device Block the paper, and then feed the paper synchronously after the paper on both sides is put in place, so as to avoid the misalignment. During this period, the operator can only wait for the paper to be completely crushed into the roller before feeding the next time, so that the next paper feeding can be carried out after the paper feeding and compounding are completed, which seriously affects the work efficiency
