Detailed Description
The utility model provides a sealing device for encapsulation is taken to chip material. The technical solution of the present invention will be described in detail below with reference to the accompanying drawings so as to be easier to understand and grasp.
The heat sealing device for packaging the chip material belt, as shown in fig. 1 to 4, includes a heat sealing mechanism 1 and a rolling mechanism 2, which are sequentially arranged along the conveying direction of the chip material belt.
Heat-seal machine constructs 1 including two hot splenium 3 of looks interval setting, and arbitrary hot splenium 3 includes fixed pile seat 4, sets up supporting shoe 5 on 4 lateral walls of fixed pile seat, sets up the hot pressing plate 6 that possesses towards supporting shoe lifting displacement on fixed pile seat.
The rolling mechanism 2 includes a carrier main body 7 and a rotation shaft 8 provided on the carrier main body 7 and having a rotation displacement, the rotation shaft 8 is provided with two rotation support plates 81 provided at intervals, the carrier main body 7 is provided with two auxiliary crimping roller discs 9 fitted to the rotation support plates 81 in a one-to-one correspondence, and the auxiliary crimping roller discs 9 have a floating crimping displacement relative to the rotation support plates 81.
The specific implementation process and principle description are as follows:
when the chip material belt is packaged, the chip base belt and the sealing film are oppositely overlapped, and the overlapped chip material belt firstly passes through the heat sealing mechanism 1 and then enters the rolling mechanism 2.
The both sides in chip material area can support on supporting shoe 5, and along with the marching type displacement in chip material area, hot pressboard 6 pushes down hot pressing involution operation, accomplishes the back at the avris heat-seal, and the roll gap that reentrants between supplementary crimping roller dish 9 and the rotation support disk 81 carries out the roll-in pressure and consolidates, so can carry out the roll-in when the heat-seal membrane is not completely solidified, ensures that the banding is sealed and level and smooth, has improved the heat-seal quality of seal membrane.
