Technical principle and design analysis of water-based glue compounding machine (Continued)

4 analysis and design of transmission system Since the compounding process requires that all parts transmit, we need to do the following. The effect of the important interrupt switch for sending the base material is that when the operator manually interrupts the experimental machine when an abnormal state occurs in the experiment, the task linear speed must be consistent. Therefore, the motion parameter of the pressing roller is the main motion parameter of the compounding machine, and the motion of all parts should be based on this parameter The linear speed of the pressing roller is determined according to the requirements of the laminating process, paper specification and work efficiency The compounding speed of SF950 water-based glue compounding machine is controlled by stepless speed regulation. The transmission principle of 4 ~ 15m/950 water-based glue compounding machine is shown in Figure 3 The power is driven by the electromagnetic speed regulating motor through the belt

wheels and sprockets are transmitted to the pressing roller, which is driven by the chain on the pressing roller in three lines: one is transmitted to the glue coating device through the rapid development of z7 and Z8 gas turbine technology and its combined cycle and a pair of Z6 gears; One is transmitted to the winding device through the sprocket Z5, Z9, Z10 and Z11 gears; The other one is transmitted to the paper feeding device through a pair of Z12 gears and sprockets Z13 and z14 In order to keep the film edge position linear and consistent during the transfer process, an arc-shaped film spreading and deviation correction mechanism is designed to control the uniform tension and minimum deviation of the film during the transfer process In addition, in order to make the product in

during the winding process, the speed of the conveying line is always consistent with that of the pressing roller, and a synchronous winding adjustment mechanism is designed, as shown in Figure 4 When the radius of the rewinding product increases, friction slip occurs between the friction disc and the transmission gear, so as to ensure that the rewinding linear speed of the rewinding product is consistent with the linear speed transmitted by the pressing roller

Analysis and design of

5 pressing mechanism

the uniformity of pressing pressure and the reliability of pressure regulation are the technical keys to the design of pressing mechanism The pressing mechanism uses the line pressure between the pressing iron roller and the pressing rubber roller to press different substrates into composite products through adhesive The pressing pressure is the most difficult index to control for the SF950 water-based glue compounding machine If the pressure is too small, the adhesive can not effectively and evenly penetrate into the paper-based fiber, and the peel strength is low; If the pressure is too high, it will make the composite products wrinkle For this reason, the SF950 water-based glue compounding machine is designed as an adjustable pressing mechanism, as shown in Figure 5 Adjust the lifting screw sleeves at both ends to make the bus clearance of the two rollers consistent The pressure can be adjusted by turning the central shaft through the handle to make the eccentric cams at both ends rotate at the same angle, so as to ensure that the linear pressure of the pressing rubber roller and the pressing iron roller is uniform. Under the action of the eccentric cam, the adjusting seats at both ends can be raised or lowered at the same time, so as to achieve different pressures between the two rollers

according to the characteristics of the compound machine, the general layout is carried out by applying the industrial design principle [6 ~ 8], as shown in Figure 6
