Embodiment Construction
[0012] As shown in the figure, the film feeding mechanism of the strapping machine of the present invention includes an unwinding shaft 1. The shaft end of the unwinding shaft 1 is connected to a reducer 2 with a self-locking function. The reducer 2 is a worm gear reducer, and the film of the unwinding shaft 1 is sent The path is provided with a front guide roller 3, a floating guide roller 7 and a rear guide roller 9 in sequence. The floating guide roller 7 is set to float up and down on the guide roller bracket 12. The two ends of the floating guide roller 7 are connected to the lifting slider 8, The up and down movement of 8 is guided by the vertical guide column 6 installed on the guide roller bracket 12, the lower spring is provided under the lifting slider 8, which plays the role of buffer, and the upper spring of the lifting slider 8 is provided to play a role in buffering. The role of making the floating guide roller quickly return and assisting in tensioning the film, ...

The invention discloses a film feeding mechanism of a strapping machine. The film feeding mechanism comprises a pay-off shaft and is characterized in that the shaft end of the pay-off shaft is connected with a reduction gear with a self-locking function; a film discharging path of the pay-off shaft is sequentially provided with a front guide roller, a floating guide roller and a rear guide roller;the floating guide roller floats up and down on a guide roller support; an upper electric eye is correspondingly arranged in the upper limit position of the floating guide roller; a lower electric eye is correspondingly arranged in the middle position of the floating guide roller; a brake block is arranged above the rear guide roller and moves up and down; the up-down motion of the brake block ispushed by a braking air cylinder; and in the film feeding process, when the floating guide roller passes through the lower electric eye from bottom to top, the lower electric eye controls the reduction gear to work, when the floating guide roller reaches the upper limit position, the upper electric eye controls the braking air cylinder to move and controls the reduction gear to stop working in adelayed mode, and during the delayed time, the floating guide roller moves from the upper limit position to the lower limit position according to the length of the film discharged from the pay-off shaft. According to the film feeding mechanism of the strapping machine, fast and accurate film feeding can be achieved, and the strapping speed and quality of the strapping machine are guaranteed.
Description
technical field [0001] The invention relates to a strapping machine, in particular to a film feeding mechanism of the strapping machine. Background technique [0002] The strapping machine is a machine that bundles packages with strapping straps to complete the strapping operation. If the strapping uses film, then the strapping machine needs to use a film feeding mechanism. Whether the film feeding action of the film feeding mechanism is fast and accurate is an important factor to ensure the strapping speed and quality of the strapping machine. The film feeding mechanism of the strapping machine in the prior art is difficult to realize fast and accurate film feeding. Contents of the invention [0003] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a film feeding mechanism of a strapping machine that can realize fast and accurate film feeding action to ensure the speed and quality of the strapping mac...
