Problems solved by technology

However, this feeding and unwinding mechanism 90 needs to use two motors (i.e., the feeding motor 91 and the unwinding motor 93), resulting in more power consumption; For point contact, the strapping 92 is not clamped enough, causing the strapping 92 to be easily slipped during the unwinding process, and the articles cannot be effectively tightened.

Embodiment Construction

[0051] The preferred structure of the present invention will be described as follows with reference to the accompanying drawings, which are only examples but not intended to limit the embodiment:

[0052] figure 1 A portal-type strapping machine is shown, which includes a portal-shaped bow frame 10, a host heart 11, a telescoping member 15, and two belt lanes 13,131. The host heart 11 is installed between an upper beam 12 and a lower beam 121, and the two ends of the upper beam 12 can be displaced by the drive of sprocket and chain (not shown), so that the host heart 11 can move up and down together. Belt tracks 13 , 131 are located on two longitudinal sides of the main engine heart 11 , and the two ends of the lower beam 121 are respectively connected to the belt tracks 131 , 31 . The telescopic member 15 is in the form of a track and is movably installed inside a frame 16. When the baling operation is to be performed, the telescopic member 15 will be driven to protrude fro...

Abstract

A feeding and reversing mechanism 3 for a strapping machine includes a forward-reverse wheel assembly 30 and a tension wheel assembly 40 which are mounted on a base 200 and arranged in such a way to provide large contact areas between a strapping band 18 and the two wheel assemblies 30, 40. The feeding and reversing mechanism 3 further includes first and second spring units (43, 45, figure 4). The first spring unit 43 helps to keep a suitable gap between an active wheel 41 and a passive wheel 42 of the tension wheel assembly 40 for the strapping band 18 to pass through. The second spring unit 45 helps to move the passive wheel 42 toward the active wheel 41 of the tension wheel assembly 40, so that the strapping band 18 can be clamped between the passive wheel 42 and the active wheel 41 tightly to facilitate reversing and tightening of the strapping band 18.

Description

technical field [0001] The invention relates to a strapping machine for bundling articles with a strapping belt, in particular to a feeding and unwinding mechanism of the strapping machine used to drive the strapping belt forward and back. Background technique [0002] Figure 10 Shown is a conventional strap feeding and unwinding mechanism 90 , which includes a tape feed motor 91 and a tape feed motor 93 . The tape feed motor 91 can drive the tape feed wheel 911, so that the packing tape 92 in the tape storage box is sent out to bundle the articles; The strap 92 is used to bundle the items. Furthermore, the first sensor 94 calculates the number of rotations of the feed pulley 911 and the second sensor 95 calculates the number of rotations of the unwinding pulley 931, so that the length of the baling belt 92 consumed by the bale can be measured, Therefore, tape replenishment and tape supply can be accurately performed. However, this feeding and unwinding mechanism 90 need...
