Abstract
The utility model discloses a longitudinally-folding mechanism of an envelope machine. According to the technical scheme, the longitudinally-folding mechanism of the envelope machine is characterized by comprising a machine frame, an upper folding plate and a lower folding plate, the upper folding plate and the lower folding plate respectively comprise a starting end and a stopping end in the envelope conveying direction, the side, far away from the lower folding plate, of the upper folding plate is upwards bent, and the curvature of the side, far away from the lower folding plate, of the upper folding plate is gradually increased in the envelope conveying direction to enable the stopping end of the upper folding plate to be located above the stopping end of the lower folding plate. According to the longitudinally-folding mechanism of the envelope machine, paper clamping can be effectively reduced, and the processing efficiency can be improved.
Description
Technical field
The utility model relates to a kind of making field of envelope, and more particularly, it relates to a kind of longitudinal folding mechanism of envelop machine.
Background technology
Envelope machine is the plant equipment for the production of envelope, mainly comprises paper-feeding mechanism, creasing mechanism, fold mechanism and applying glue mechanism.Fold mechanism is subdivided into Zong Zhe mechanism and cross turnbacking mechanism, and envelope completes the folding work of envelope by Zong Zhe mechanism and cross turnbacking mechanism.Existing Zong Zhe mechanism is made up of upper flap and lower flap portion conventionally, the envelope both sides that make arranged in a crossed manner by upper flap and lower flap portion form flanging as shown in Figure 1, but existing upper flap and lower flap portion are set to straight tabular strip structure conventionally, the phenomenon that paperboard often occurs in process, affects working (machining) efficiency.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide one can effectively reduce paper jam phenomenon generation, promotes the longitudinal folding mechanism of envelop machine of working (machining) efficiency.
For achieving the above object, the utility model provides following technical scheme: a kind of longitudinal folding mechanism of envelop machine, comprise frame, upper flap and lower flap portion, described upper flap and lower flap portion include top and the end along envelope throughput direction, described upper flap is bent upwards away from a side of lower flap portion, and upper flap increases gradually and makes upper flap end be positioned at the top of lower flap portion end along its curvature of envelope throughput direction away from a side of lower flap portion.
By adopting technique scheme, the flanging of envelope is turned down the curved surface that moves to top, upper flap top and be bent to form in the side direction away from lower flap portion along upper flap, because the turnover process of envelope flanging is that the curved surface increasing gradually along a curvature carries out, therefore Foldable envelope is more smooth, reduce the generation of envelope paper jam phenomenon, promoted working (machining) efficiency.
The utility model is further set to: described lower flap portion is fixedly connected with frame, and described upper flap and frame removably connect.
By adopting technique scheme, can change to upper flap the flanging style of dismantling and adjust folding envelope at any time.
The utility model is further set to: described frame is provided with horizontally extending backstay, and described upper flap is provided with connecting portion, and described connecting portion is socketed on backstay.
By adopting technique scheme, the socket of connecting portion and backstay makes the flap can be along backstay slippage, makes to regulate horizontal range between flap and the lower flap portion size with change envelope two side edgefolds.
The utility model is further set to: the position that described connecting portion is connected with backstay is provided with the positioning screw hole for fixing upper flap.
By adopting technique scheme, can be fixed upper flap by bolt, and the mobile upper flap of dismounting also more for convenience.
The utility model is further set to: described upper flap top bends downwards, and described lower flap portion top upwards bends.
By adopting technique scheme, make envelope more be more prone to enter between flap and lower flap portion in both sides, further prevent the generation of paper jam phenomenon.

Detailed description of the invention
Referring to figs. 1 through Fig. 4, the utility model longitudinal folding mechanism of envelop machine embodiment is described further.
A kind of longitudinal folding mechanism of envelop machine, comprise frame 1, upper flap 2 and lower flap portion 3, described upper flap 2 and lower flap portion 3 include along the top 4 of envelope throughput direction and end 5, described upper flap 2 is bent upwards away from a side of lower flap portion 3, and upper flap 2 increases gradually and makes upper flap 2 ends 5 be positioned at the top of lower flap portion 3 ends 5 along its curvature of envelope throughput direction away from a side of lower flap portion 3.The flanging 9 of envelope is turned down the curved surface that moves to upper flap 4 tops, 2 top and be bent to form in the side direction away from lower flap portion 3 along upper flap 2, because the turnover process of envelope flanging 9 is that the curved surface increasing gradually along a curvature carries out, therefore Foldable envelope is more smooth, reduce the generation of envelope paper jam phenomenon, promoted working (machining) efficiency.
Described lower flap portion 3 is fixedly connected with frame 1, and described upper flap 2 removably connects with frame 1.Can change to upper flap 2 flanging 9 styles of dismantling and adjust folding envelope at any time.
Described frame 1 is provided with horizontally extending backstay 6, and described upper flap 2 is provided with connecting portion 7, and described connecting portion 7 is socketed on backstay 6.Connecting portion 7 and the socket of backstay 6 make the flap 2 can be along backstay 6 slippages, make to regulate horizontal range between flap 2 and lower flap portion 3 to change the size of envelope two side edgefolds 9.
The position that described connecting portion 7 is connected with backstay 6 is provided with the positioning screw hole 8 for fixing upper flap 2.Can be fixed upper flap 2 by bolt, and the mobile upper flap 2 of dismounting also more for convenience.
Described upper flap 2 tops 4 bend downwards, and described lower flap portion 3 tops 4 upwards bend.Make envelope more be more prone to enter between flap 2 and lower flap portion 3 in both sides, further prevent the generation of paper jam phenomenon.
