Embodiment 1

[0027] Embodiment one, see figure 1 , a portable paper bag hand rope fixed-length cutting mechanism, including a frame 1. The frame 1 includes a main body 11 extending in the left-right direction, a left end plate 12 disposed at the left end of the main body 11 , and a right end plate 13 disposed at the right end of the main body.

[0028]Both the left end plate 12 and the right end plate 13 are located in a vertical plane extending in the front-rear direction. The right side of the left end plate 12 is provided with a cutter 7 . A feeding spring 8 is arranged between the cutter 7 and the left end plate 12 . The left end plate 12 is provided with a hand rope positioning hole 9 passing through the left end plate along the left and right directions. The left side of the left end plate 12 is fixedly connected with a cylinder 2 and a drive rod 3 is pierced therethrough. The air cylinder 2 and the drive rod 3 extend in parallel and in the left-right direction. The piston rod o...

Embodiment 2

[0038] Embodiment two, see Figure 6 , the difference from the first embodiment is that an opening block 51 matching with the first opening guide surface 511 is provided on the first clip 42 .

[0039] see Figure 7 , the middle part of the cutter folding rod 76 is hinged on the left end plate 12 to form a lever structure, and the left end of the cutter folding rod 76 is provided with an inclined lead-in rod 763 . When the driving rod 3 moved to the right, the driving block 31 slid along the lead-in rod 763 so that the right end of the cutter closing bar 76 was raised up, and the result of driving the right end of the closing bar 76 was raised so that the front end of the chopping block 72 and the blade 73 were closed and the rear end opened. Open and complete the cutting action.

Embodiment 3

[0040] Embodiment three, see Figure 8 The difference from the first embodiment is that the protruding head 441 doubles as the opening block 51 at the same time. An inclined surface 531 is provided on the locking block 53 in the open state, and the inclined surface 531 constitutes an opening guide surface for opening the chuck. The opening block is no longer provided on the right end plate.

Abstract

The invention relates to portable paper bag production equipment, in particular to a fixed-length cutting-off mechanism for carrying hand straps of a portable paper bag. The cutting-off mechanism comprises a rack, a clamping head opening maintaining structure, a cutter, a cylinder arranged on the rack and carrying hand strap positioning holes formed in the rack. A clamping head and a drive rod are connected with the cylinder, the cutter comprises a cutting board, a blade, a cutter opening spring and a cutter folding rod, the cutting board is connected to the rack, and the blade is hinged to the cutting board. The drive rod is provided with a drive block matched with the cutter folding rod. The clamping head comprises a first clamping piece, a second clamping piece hinged to the first clamping piece and a clamping head folding spring. The clamping head opening maintaining structure comprises a first blocking-connecting part arranged at one end of the rack, a second blocking-connecting part arranged at the other end of the rack, an opening state locking block, an opening guiding face and an opening block, and the carrying hand strap positioning holes and the first blocking-connecting part are located at the same end of the rack. The problems that manual carrying hand strap cutting is low in production efficiency, the lengths of cut straps is poor in uniformity, and operation is laborious are solved.

Description

technical field [0001] The invention relates to production equipment for portable paper bags, in particular to a fixed-length cutting mechanism for a hand rope of a portable paper bag, which belongs to the field of portable paper bag processing. Background technique [0002] There are two kinds of structures for the user to carry the existing portable paper bag, one is the hand hole directly opened on the bag body, and the other is to be connected to the bag body to carry the hand. [0003] In Chinese Patent No. 2004200254298, the date of authorization announcement is March 2, 2005, and the patent literature titled "handy paper bag" discloses a kind of handy paper bag made of bag rope (handle) and bag body. [0004] Before the hand rope is installed on the bag body, it exists in the form of a long rope, and the long rope is cut into the hand rope of the required length according to needs during use. The existing method of cutting the handle rope from the long rope is manual...
