摘要： A feeding and reversing mechanism for a strapping machine includes a forward-reverse wheel assembly and a tension wheel assembly which are mounted on a base and arranged in such a way to provide larger contact areas between a strapping band and the two wheel assemblies. The feeding and reversing mechanism further includes first and second spring units. The first spring unit helps to keep a suitable gap between an active wheel and a passive wheel of the tension wheel assembly for the strapping band to pass through. The second spring unit helps to move the passive wheel toward the active wheel of the tension wheel assembly, so that the strapping band can be clamped between the passive wheel and the active wheel tightly to facilitate reversing and tightening of the strapping band.

摘要： A tape support for an automatic wrapper includes a main frame and an internal frame. The internal frame is keyed onto the main frame and has four corners. A corner block is keyed to each corner of the main frame. A guide blade assembly is pivotally keyed onto two vertical sides of the main frame, and an adjustment assembly is keyed onto two vertical sides of the main frame. The corner block has three sides. One is concave, and the others form a right angle. The guide blades face each other and wrap around the internal frame. The arms of the adjustment assembly face each other and wrap around the blade assembly. A brush is mounted on the free ends of the adjustment assembly to guide the tape to the middle by its retaining force when the tape passes through the brush.

摘要： A reverse tension mechanism for a strapping machine includes an active wheel, a supporting arm installed with a passive wheel, a lever, and a spring. The supporting arm can be moved relative to the active wheel so that a strapping band which passes through between the passive wheel and the active wheel is clamped to control retracting and tightening of the strapping band. A first end of the lever is pivotably connected to a section of the supporting arm, and the spring is vertically installed between a second end of the lever and the section of the supporting arm. The first end of the lever can be activated by a cam to press the spring vertically to produce pushing force to swing the supporting arm.
摘要翻译： 用于捆扎机的反向拉力机构包括主动轮，安装有被动轮的支撑臂，杠杆和弹簧。 支撑臂可以相对于主动轮移动，从而夹紧通过被动轮和主动轮之间的捆扎带，以控制捆扎带的收缩和收紧。 杠杆的第一端可枢转地连接到支撑臂的一部分，并且弹簧垂直地安装在杠杆的第二端和支撑臂的部分之间。 杠杆的第一端可以由凸轮激活，以垂直地按压弹簧以产生推动力以摆动支撑臂。

摘要： A strapping head assembly has a central axle, a braking tube, a lower securing plate, a braking pad, an adjusting base, a biasing member, an adjusting nut, a strap-holding collar and an upper holding base. The braking tube is mounted rotatably around the central axle. The lower securing plate is mounted on the bottom of the braking tube. The braking pad is attached to the top of the braking tube. The adjusting base is adjustably mounted on the central axle and abuts with the braking pad. The biasing member is mounted around the central axle and abuts against the adjusting base. The adjusting nut is screwed with the central axle and abuts with the biasing member. The strap-holding collar is mounted around the central axle. The upper holding base is mounted around the central axle and has an abutting flange mounted over the strap-holding collar.
