Detailed Description

As shown in fig. 1, 2 and 4, paper bag machine's perforating device, including frame 9, be equipped with base 1, the sword 2 that punches a hole and the power unit that drives the sword up-and-down motion of punching a hole on the paper bag transfer path of frame 9, the round hole sets up with the sword 2 that punches a hole from top to bottom relatively, as shown in fig. 5, the end of punching a hole of the sword 2 that punches a hole has the breach 21 of the type V-groove of inversion, and the type V-groove of this department can be the V-groove, also can be the U-shaped groove, as long as with the breach of the similar shape of V-shape all can, the double-phase offside of breach 21 is cutting edge 22, round hole 1 and sword 2 looks adaptation that punch a hole, during punching, the cutting edge of the sword 2 that punches a hole inner wall is hugged closely to the paper and inserts round hole 1, the cooperation of cutting edge and round hole inner wall is equivalent to the scissors, and the paper surface is run through in direct cutting.

The punching knife 2 can be arranged on the rotary punching upper wheel 5, the base can be arranged on the rotary punching lower wheel, and the punching knife moves downwards in the rotating process and is inserted into the round hole of the base to punch; the punching knife can also be arranged on a fixed support, the base is fixed, and the punching knife moves up and down to be inserted into the round hole for punching.

As shown in fig. 4, in this embodiment, the frame 9 is provided with an upper transmission shaft 3 and a lower transmission shaft 4 which rotate synchronously, the punching blade 2 is radially disposed on the upper punching wheel 5, the base 1 is disposed on the circumferential surface of the lower punching wheel 6, the upper punching wheel 5 is in transmission connection with the upper transmission shaft 3, the lower punching wheel 6 is in transmission connection with the lower transmission shaft 4, and the paper bag conveying path is located between the upper punching wheel 5 and the lower punching wheel 6. The container bag conveys and punches when punching between upper wheel 5 and the lower wheel 6 that punches a hole, and the sword 2 that punches a hole rotates along with upper wheel 5 that punches a hole, and round hole 1 rotates along with lower wheel 6 that punches a hole, and when sword 2 that punches a hole and round hole 1 rotate to relative department from top to bottom (department of punching a hole promptly), the sword 2 that punches a hole stretches out the upper wheel 5 that punches a hole and inserts in the round hole 1 and punch a hole.

The punching machine is characterized in that an upper cross beam 11 and a lower cross beam 12 are arranged on the machine frame 9, an upper adjusting support 10 used for adjusting the left and right positions of the punched upper wheel is arranged on the upper cross beam 11, and a lower adjusting support 13 used for adjusting the left and right positions of the punched lower wheel is arranged on the lower cross beam 12. The upper adjusting bracket 10 can move left and right on the upper cross beam 11, and the lower adjusting bracket 13 can move left and right on the lower cross beam 12, so that the punching position of the punching knife and the hole distance can be adjusted.

As shown in fig. 3, in the present embodiment, an upper fixture block 14 is disposed on the upper adjusting bracket 10, an annular groove one 15 is disposed on the outer ring of the upper punching wheel 5, and the upper fixture block 14 can be inserted into the annular groove one 15, so that the lower punching wheel 6 can rotate but cannot move axially. And a lower clamping block 16 is arranged on the lower adjusting bracket 13, an annular groove II is formed in the outer ring of the punching lower wheel 6, and the lower clamping block 16 can be inserted into the annular groove II, so that the punching lower wheel can rotate but cannot axially move.

Power unit includes cam 7, cam 7 is fixed in on adjusting bracket 10, just cam 7 and the coaxial setting of the upper wheel 5 that punches a hole, though cam 7 overlaps on last transmission shaft 3, but the aperture ratio goes up the diameter of transmission shaft big, consequently even the transmission shaft rotates and also can not drive the cam and rotate, punching knife 2 and the contact of cam 7 profile, punching knife 2 is connected with elastic component 8, can drive the upper wheel 5 that punches a hole when last transmission shaft 3 rotates and rotate, and the upper wheel 5 that punches a hole rotates and can drive punching knife 2 and rotate, because the pulling force of elastic component makes 2 upper ends of punching knife push up the profile of cam 7 all the time, and punching knife 2 pivoted in-process can carry out the up-and-down motion along the profile of cam 7.

The round hole 1 is communicated with the waste paper collecting cavity, so that waste scraps can fall into the waste paper collecting cavity.
