一、概述枕式包装机的横封头是完成包装袋的横向封口工步的一对电热块。如图1所示,已经纵封的塑料薄膜2以及其中的物品1 (如糖果块、面包等),经过横封头4和6的滚压,完成横封工步,然后经切断,即为成品(有的切断工步在横封过程中完成)。两个横封轴7内设有电阻加热装置,将横封头加热到所需要的热封温度,齿轮对3驱动两个热封头作同步而方向相反的转动。
First, an overview of the pillow packing machine horizontal head is to complete the transverse sealing bag sealing step of a pair of electric block. As shown in FIG. 1, the plastic film 2 which has been longitudinally sealed and the object 1 (such as candy pieces, breads, etc.) are rolled by the transverse heads 4 and 6 to complete the transverse sealing step and then cut, that is, Finished products (some cut off the step in the horizontal sealing process completed). Two transverse sealing shaft 7 is provided with a resistance heating device, the transverse head is heated to the required heat sealing temperature, the gear pair 3 drives the two heat sealing heads for synchronous and opposite rotation.
