Description

Perforation knife system in a kind of paper bag production equipment

Technical field:

The utility model belongs to mechanical equipment technical field, relates to the paper bag production equipment, refers in particular to the perforation knife system in a kind of paper bag production equipment.

Background technology:

Existing doing in the paper bag process, generally be to adopt knife apparatus directly to cut off, because it all is concordant that cutting knife directly cuts off the sack edge of paper bag, add packing, transportation is impaction state, like this, people open the just comparatively inconvenience of paper bag sack, being difficult to when fitly sticking together just as two pieces of paper separate in use.

The utility model content:

The purpose of this utility model is to overcome the above-mentioned weak point of prior art, and the perforation knife system in a kind of paper bag production equipment is provided.

The utility model realizes that the technical scheme that its purpose adopts is: the perforation knife system in a kind of paper bag production equipment, this perforation knife system has a rotating shaft body, outer wall in described rotating shaft body is provided with at least one cutter groove, in described cutter groove, perforation blade and pressure knife block are installed, and two outsides of described cutter groove offer respectively the screw that several are used for installing the push type broach bolt.

The outer wall of described rotating shaft body is provided with two cutter grooves, and the distribution that is centrosymmetric of these two cutter grooves.

At least three perforation blades and at least two pressure knife blocks are set in described each cutter groove, and the both ends of the surface of described pressure knife block are the inclined-plane, wherein a perforation blade is limited between the inclined-plane of two adjacent pressure knife blocks.

Be provided with five perforation blades and three pressure knife blocks in described each cutter groove, wherein three perforation straight knife sheets are affixed on respectively two inboards of cutter groove, and two oblique blades of perforation then lay respectively between the inclined-plane of pressure knife block and are connected three perforation straight knife sheets in addition.

Offer respectively several recesses in the outer wall of described rotating shaft body, two outsides of cutter groove, described screw is opened in the recess.

The utility model perforation knife system is under the driving of power set, thereby the rotation of rotating shaft body drives the rotation of perforation blade, when the perforation blade rotates to the below, the paper roll that launches under the feed status is punched, and then breaks away from and so forth operation.Therefore, adopt the utility model perforation knife system, can in the paper roll course of conveying, finish paper roll is stamped perforation, but and the shape of the arrangement furnishing of perforation needs, so just can make the sack edge of the paper bag of producing present different shapes and produce not concordant effect, more Jiamei's sight is various not only to make paper bag, and is convenient for people to open and use paper bag.When the utility model uses, can control the absolute synchronization by rotating shaft body rotating speed and paper transmission speed, guarantee can in the acanthopore process, not damage paper, can guarantee bag quality and efficient.

Description of drawings:

Fig. 1 is the structural representation of a kind of embodiment rotating shaft of the utility model body;

Fig. 2 is the perspective view of a kind of embodiment perforation of the utility model knife system;

Fig. 3 is the partial top view of Fig. 2 embodiment in the utility model;

Fig. 4 is the cutaway view of Fig. 2 embodiment in the utility model.

The specific embodiment:

Below in conjunction with specific embodiments and the drawings the utility model is further specified.

Perforation knife system in a kind of paper bag production equipment described in the utility model is used for being launched under the feed status paper tape to be punched by paper roll, so that follow-up paper bag in generating separates paper bag.

Particularly, this perforation knife system has as shown in Figure 1 a rotating shaft body 1, outer wall in described rotating shaft body 1 is provided with at least one cutter groove 11, the axially parallel of cutter groove 11 and rotating shaft body 1, in conjunction with shown in Figure 4, in the present embodiment, the outer wall of rotating shaft body 1 is provided with two cutter grooves 11, and the distribution that is centrosymmetric of these two cutter grooves 11.In described each cutter groove 11, perforation blade 2 and pressure knife block 3 are installed, and the both ends of the surface of described pressure knife block 3 are inclined-plane 31, two outsides of described cutter groove 11 offer respectively several screws 12 that is used for installing push type broach bolt 4, be that perforation blade 2 and pressure knife block 3 place in the cutter groove 11, thereby make pressure knife block 3 compress perforation blade 2 by 4 lockings of push type broach bolt, make it to abut against the inboard of cutter groove 11, the cutter tooth of perforation blade 2 is exposed to the outer surface of rotating shaft body 1.

Again in conjunction with Fig. 2, shown in Figure 3, in the utility model, because cutter groove 11 has suitable width, and the both ends of the surface of described pressure knife block 3 are inclined-plane 31, therefore perforation blade 2 can be installed in respectively both sides and be and be mounted obliquely between two pressure knife blocks 3, in the present embodiment, be provided with five perforation blades 2 and three pressure knife blocks 3 in described each cutter groove 11, wherein three perforation straight knife sheets 21 are affixed on respectively two inboards of cutter groove 11, in addition two 22 on oblique blades of perforation lay respectively between the inclined-plane 31 of pressure knife block 3 and are connected three perforation straight knife sheets 21, namely 5 perforation blades 2 by 3 fixed installations of three pressure knife blocks and be connected be one as shown in Figure 3 continuous whole and the perforation cutter group of non-linear.

The utility model perforation knife system is under the driving of power set, thereby 1 rotation of rotating shaft body drives 2 rotations of perforation blade, when perforation blade 2 rotates to the below, the paper roll that launches under the feed status is punched, and then breaks away from and so forth operation.Because the perforation cutter group of punching is the perforation cutter group of a continuous whole and non-linear, like this, after finishing the punching to paper tape, the perforation that forms at paper neither straight line, therefore after process paper folding, fitting into paper bag, the sack both sides that can accomplish paper bag form certain drop, and not only the appearance novel and beautiful also is convenient for people to open paper bag and uses.

In the present embodiment, owing to having two groups of perforation blades, therefore 1 rotation of rotating shaft body can be finished twice punching in 1 week, and obviously, the length of the paper bag that the utility model can be produced is as required selected the rotating shaft body of different-diameter or the perforation blade that the choosing dress is not counted on the same group.

Offer respectively several recesses 13 in the outer wall of described rotating shaft body 1, two outsides of cutter groove 11, described screw 12 is opened in the recess 13, and push type broach bolt 4 adopts hexagon socket head cap screw, is convenient to install in small space.Push type broach bolt 4 can be absorbed in the recess 13 when mounted fully like this, avoids outstanding, keeps rotating shaft body 1 cylindrical neat, improves outward appearance and result of use.

In sum, adopt the utility model perforation knife system, can in the paper roll course of conveying, finish paper roll is stamped perforation, but and the shape of the arrangement furnishing of perforation needs, so just can make the sack edge of the paper bag of producing present different shapes and produce not concordant effect, not only make paper bag more attractive in appearance various, and be convenient for people to open and use paper bag.When the utility model uses, can control the absolute synchronization by rotating shaft body rotating speed and paper transmission speed, guarantee can in the acanthopore process, not damage paper, can guarantee bag quality and efficient.
