Operation
　　 HermeStretch II-Stretcher is composed by four completely same mechanic parts which are connected into a rectangle stretching area.With the chain-drive and trapezium whorl silk-pole-moving structure,the machine operator can easily control the tensile strength of the stretcher by turning the plastic covered handle.
The lamination of the frame and the stretching surface is finished by the moving of the four cylinder, The stroke of the cylinder can be used for varied thickn-ess of frames by adjusting the spiral bolt and therefore guarantee the quality of the silk net.

Mechanic Structure
　　Models HermeStretch IIMesh-Stretcher is mainly composed by the following five parts; frame,silk pole moving structure,chain driving ,structure,net collets and the pneumatic system.Each part has its special features; the frame is light and firm; the silk pole moving structure is accurate and has outstanding self-lock function;the chain driving structure is light and reasonably distributed; the net collets are composed with reliable and firm double rocker.Strong clamping force is the main reason to decide the quality of net stretching and our product is right beyond all other products at this point.

Mechanical stretching-mesh machine
Max mesh area: 1550×1550 mm
Min mesh area: 600×600 mm

简　介

气动式机械伸缩型绷网机是最新研制的绷网机，不但外观设计精巧、紧凑、美观、实用，而且具有结构稳固、轻便、耐用、工作可靠等优点，因而成为丝印行业中不可代替的信心产品。

操作原理

　　HermeStretch II 型绷网机，由四个完全相同的机械部分利用导轨首尾连接成矩形，其绷网范围即其四部分构成的密封面积。该气动式机械式绷网机采用链条传动及梯形螺纹丝杆位移机构，只须转动手柄便可达到拉网所需的张力。

　　网框与拉伸网面的贴合由四边的气缸动作完成，气缸的行程可通过螺栓调节以达到适用于各种厚度的网框，保证拉网的质量，不会轻易损坏网纱。

机械结构

　　HermeStretch II型绷往机主要由机架、丝杆位移机构、链轮传动机构、拉往夹头和气动系统五个部分组成。机架轻巧稳固，丝杆的传动精度高、自锁能力强，链轮传动轻便、分布合理。拉网机夹头采用双摇杆机构原理做成，是本厂的专利产品，结构合理、美观、坚固、工作可靠；夹紧力强是决定拉网质量的主要因素，也是本机优越于其它产品的主要特点。
