It is cut by cutter realization to plastic tape, but due to only having cutter to contact with plastic tape, and plastic tape Shake is easy in intermittent delivery, so that the dimensional accuracy cut is poor.

Utility model content

In view of the deficiencies of the prior art, the utility model aim is to provide a kind of Bag Making Machine, and there is plastic tape to cut ruler Very little feature with high accuracy.

To achieve the above object, the utility model provides the following technical solutions:

A kind of Bag Making Machine is disposed with conveying device, handheld ring hot-press arrangement, closing device in its rack and cuts bag Device；It is described cut it is packed set including crossbeam and blade, the sliding of the both ends of the crossbeam is arranged in the two sides of rack and is connected with drive Move its control mechanism slid up and down along rack；The inner hollow of the crossbeam, the blade sliding are arranged in the crossbeam Portion, the driving mechanism that the blade upper end setting pushes it to move up and down；On the lower end wall surface of the crossbeam along its length Offer the opening stretched out for the blade；In the end face of the blade, sliding abuts the press strip having for compressing plastic tape, institute It states press strip to stretch out from the opening, has abutted spring between the press strip and the blade；It is located at the pressure on the rack It is provided with the platform passed through for plastic tape below item, the knife seam protruded into for the blade is provided on the platform.

So set, under the action of the spring, press strip in advance compresses plastic tape, plastic tape is cut in subsequent blade incision It is disconnected；During cutting, press strip is tightlyer with pressure by plastics with spring-compressed, thus because of plastics after preventing blade contact plastic tape Band skids and generates and pull, and influences the dimensional accuracy of polybag after cutting.

Further setting: it is slid in the both ends of the surface of the blade and abuts the press strip.

So set, the press strip by blade both ends can all compress the plastic tape for being located at blade two sides, thus into one Step improves the dimensional accuracy cut.

Further setting: the first flange extended to two sides is provided in the upper end of the blade, in the upper of the press strip End is provided with the second flange abutted with the crossbeam lower end surface；Institute is abutted between first flange and second flange State spring.

It is arranged such: by the first flange of setting and the second flange, providing the contact surface of abutting for both ends of the spring, mention simultaneously The structural strength of high strap and press strip.

Further setting: it is offered on first flange and second flange for spring end insertion Blind hole.

It is arranged such: by adding blind hole, so that spring both ends in stress do not shift, to improve transmission essence Degree.

Further setting: the driving mechanism includes connecting rod, mandril and fixed link；The cross is protruded into the lower end of the mandril It beam and is abutted with the blade upper end, the crossbeam is stretched out in the upper end of the mandril, and the fixed link is fixed at the cross The upper end of the upper surface of beam, the middle part of the connecting rod and the fixed link is rotatablely connected；In one end and the top of the connecting rod The upper end of bar is flexibly connected, and the other end is connected to the upper edge of rack.

Be arranged such: when crossbeam moves down, connecting rod one end abuts rack, and the other end pushes mandril to move down with cutting blade, Realization cuts movement.

Further setting: the guide sleeve protruded into for the mandril is provided in the upper end of the crossbeam.

So set, cooperating by adding guide sleeve and mandril, the kinematic accuracy of mandril axial direction is improved, reduces shake.

Further setting: the top stem casing is equipped with reset spring, and the upper end of the reset spring is abutted with the connecting rod, under End abuts the crossbeam.

Be arranged such: by adding reset spring, so that rising in crossbeam, connecting rod, which is detached from pushing rod with rack, to be resetted Accurately.

Further setting: rubber sleeve is arranged in one end that the connecting rod is abutted with rack.

It is arranged such: by adding rubber sleeve, preventing connecting rod and rack from directly touching and wearing the two, while reducing two The noise that person generates when touching.

In conclusion the utility model has the following beneficial effects:

1. blade movement is steady, motion stability；

2. press strip is capable of providing biggish pressure, so that when cutting band, plastic tape is non-slip, to guarantee to cut rear plastics The dimensional accuracy of bag.
