This mechanism includes feeding press roller, ejection of compact compression roller and snub pulley, feeding press roller and ejection of compact compression roller are tangent in front upper place and back upper place and snub pulley respectively, formation can be drawn into with feed end and the discharge end of seeing the sheet off, there is a locating piece feeding press roller front upper place, and the position relative with feeding roller feed direction is provided with the location contained angle on the locating piece, makes the sheet edge of entering can be by spacing, the feeding press roller surface is provided with the last negative pressure suction inlet that can adsorb raw materials sheet hem section. The utility model discloses a setting has the roller system of negative pressure suction inlet, can move towards by the marginal of effective control raw materials sheet, makes it fixed a position by the locating piece reliably to accomplish the hem process, whole mechanism structure is simple, the reliability is high, has improved the hem quality.
Description
Technical field
This utility model belongs to packaging facilities, is related to a kind of for carrying out to raw material sheet material edge in automatic paper bag production line
Fold to form the sheet material edge-folding mechanism of flanging.
Background technology
Automatically paper bag machine generally adopts rectangular sheet for raw material, by the bonding on side and base, forms paper bag.In order that
Tear is difficult after paper bag edge connection handle, it usually needs flanging reinforcement is carried out to the corresponding sheet edge of bag mouth, is to increase strong
Degree.If produced using artificial flanging, low production efficiency, unsightly, quality is also unstable.And existing automatic flanging equipment is logical
Often the conveying direction of sheet material is controlled using the setting of roller system, and by realizing folding process to the spacing of sheet material end, form folding
Side.But such edge-folding mechanism, when flanging is carried out to relatively thin sheet material, as sheet material is softer, end is easily sagging, causing can not
By retaining tips, so that flanging baulk, increased percent defective.
The content of the invention
Main purpose of the present utility model is：Offer is a kind of can to carry out pre-flanging operation to relatively thin softer sheet material, roll over
Side reliable in action, the good sheet material edge-folding mechanism of product processing quality.
Sheet material edge-folding mechanism of the present utility model, including charging pressure roller, discharging pressure roller and snub pulley；Charging pressure roller and discharging
Pressure roller is tangent with snub pulley in front upper place and back upper place respectively, and formation can be involved in and send the feed end and discharge end of sheet material；
There is a positioning block charging pressure roller front upper place, and on locating piece, the position relative with feed roller feedstock direction is provided with positioning angle, makes
Into sheet edge can be limited；The charging roller surface is provided with adsorbing the upper negative pressure of raw material sheet material flanging section
Suction inlet.
Further, the subiculum roller surface is provided with adsorbing raw material sheet material main body and aids in the lower negative pressure being sent into inhale
Mouthful.
Further, in subiculum roller surface, parallel direction is arranged with two rows to the lower negative pressure suction inlet vertically.
Further, the mounting bracket of the charging pressure roller and discharging pressure roller is located at the adjustable track of snub pulley radial direction
On, and drive which to be pressed on snub pulley along adjustable track by compression spring.
The utility model has the advantages that：By arranging the roller system with negative pressure suction inlet, it is capable of effective control raw material sheet material
Move towards at edge so as to can reliably be positioned block positioning, so as to complete flanging process；Whole mechanism structure is simple, reliability
Height, improves flanging quality.
Description of the drawings
Fig. 1 is positioned the state before rear flap folded for raw material sheet material end in this utility model embodiment course of work and shows
It is intended to；
Fig. 2 is the view during raw material sheet material flap folded in this utility model embodiment course of work.
Specific embodiment
As shown in Figure 1 and Figure 2, the sheet material edge-folding mechanism of this utility model embodiment, including charging pressure roller 4, discharging pressure roller 1,
Snub pulley 6, charging pressure roller 4 and discharging pressure roller 1 respectively in front upper place and back upper place and snub pulley tangent 6, formation can be involved in
Send the feed end and discharge end of sheet material；There is a positioning block 3 charging pressure roller front upper place, with feed roller feedstock direction phase on locating piece
To position be provided with positioning angle, enable the sheet edge of entrance limited；The charging roller surface is provided with
The upper negative pressure suction inlet 5 of absorption raw material sheet material flanging section.Subiculum roller surface is provided with adsorbing raw material sheet material main body and auxiliary is sent
The lower negative pressure suction inlet 7 for entering.In subiculum roller surface, parallel direction is arranged with two rows to lower negative pressure suction inlet vertically.Charging pressure roller and discharging
The mounting bracket of pressure roller is located on the adjustable track of snub pulley radial direction, and drives which to lean on along adjustable track by compression spring 8
It is pressed on snub pulley.
The course of work of this utility model embodiment is as follows：
When raw material sheet material is initially entered between charging pressure roller 4 and snub pulley 6, the upper negative pressure suction nozzle fed on pressure roller 4 is arrived
Up to raw material sheet material P flanging section and adsorb flanging section, as the continuation of sheet material is sent into, flanging section is adsorbed upper to lift, and reaches certain
Deflate after angle, now end extends the positioning angle on locating piece 3 limited, i.e., position as shown in Figure 1, now snub pulley
On lower negative pressure suction raw material sheet material.
With in raw material sheet material back segment continuation be sent into, due to sheet material front end it is limited, therefore edge start fold, formed
Flanging, the flanging after folding go successively to discharge between pressure roller 1 and snub pulley 6, i.e., position as shown in Figure 2, are then squeezed into
Type is simultaneously sent, and completes flanging process.
