Fig. 1-Fig. 3, a kind of bag making point valve gear 100 that the utility model embodiment provides, including pedestal 10 are please referred to, Emptying roller 12, hitch structure 14, press material structure 16 and cutting structure 18 are provided on pedestal 10.Auxiliary material is stored on emptying roller 12 20.Hitch structure 14 does straight reciprocating motion under the drive of brace and connecting rod framework to drive the advance of auxiliary material 20, press material structure 16 For auxiliary material 20 to be pressed to major ingredient, cutting structure 18, which cuts auxiliary material 20, is bonded in the interval of auxiliary material 20 on major ingredient.

Bag making point valve gear 100 in the utility model embodiment, which can be realized automatically, bonds 20 discontinuous of auxiliary material Operation on to major ingredient improves bag making efficiency.

In some embodiments, emptying roller 12 is arranged on movable plate 11, and movable plate 11 can be in the width side of auxiliary material 20 It moves up.

In this way, after 20 material volume of auxiliary material more renewed auxiliary material 20 can be adjusted on emptying roller 12 by adjusting movable plate 11 Position, keep auxiliary material 20 be aligned always in the vertical direction.

In some embodiments, movable plate 11 is threadedly coupled by 13 connection base frame 10 of screw rod, screw rod 13 and pedestal 10, Screw rod 13 drives movable plate 11 mobile relative to pedestal 10.

In this way, structure is simple, it is easily operated.

In some embodiments, tensioner arm 112 is provided on movable plate 11, the end of tensioner arm 112 is provided with tensioning Roller 114 offers vertical slot 15 on pedestal 10, and idler roller 114 is swingably arranged in vertical slot 15.

In this way, when the pulling force being subject in 20 traveling process of auxiliary material changes, the upper bottom in vertical slot 15 of tensioner arm 112 It is dynamic, the pulling force that auxiliary material 20 is subject to is adjusted, auxiliary material 20 is prevented to be broken by over-tension.

Specifically, tensioner arm 112 connects movable plate 11 by connecting rod, and connecting rod is fixedly connected with movable plate 11, is tensioned Arm 112 and connecting rod rotation connection.One end of tensioner arm 112 is arranged in idler roller 114, and the other end of tensioner arm 112 passes through bullet Spring connects movable plate 11.When the pressure that auxiliary material 20 is subject to changes, tensioner arm 112 is using the tie point with connecting rod as axle center It rotates, adjusts the pressure that auxiliary material 20 is subject to.

In some embodiments, brace and connecting rod framework includes motor 32 and drive rod 34, drive rod 34 and motor 32 Eccentric shaft cooperation is exported, drive rod 34 connects motor 32 and hitch structure 14.Mounting hole 17, hitch structure are offered on pedestal 10 14, which wear mounting hole 17, connects drive rod 34, and 17 relatively horizontal orientation of mounting hole is obliquely installed, the inclined direction of mounting hole 17 and The direction of travel of auxiliary material 20 is consistent.

In this way, motor 32 works, output shaft rotation drives drive rod 34 to do linear reciprocating motion, so that traction be driven to tie Structure 14 does linear reciprocating motion.

Specifically, in present embodiment, what one end that drive rod 34 and motor 32 connect was done is incomplete circular motion.

In some embodiments, guide rail 172, length direction of the guide rail 172 along mounting hole 17 are provided on mounting hole 17 Setting, hitch structure 14 are slidably arranged on guide rail 172.

In this way, drive rod 34 drives hitch structure 14 to do stable straight reciprocating motion on guide rail 172, realize auxiliary material 20 discontinuous improve the stability of the movement of hitch structure 14 to the effect of front haulage, also ensure the stabilization that auxiliary material 20 advances Property.

It in some embodiments, further include material folding structure 40, material folding structure 40 and hitch structure 14 are disposed adjacent, material folding Structure 40 can clamp auxiliary material 20, and material folding structure 40 and hitch structure 14 staggeredly work.

In this way, hitch structure 14 clamps auxiliary material 20, material folding structure 40 unclamps auxiliary material 20, before hitch structure 14 drives auxiliary material 20 Into a distance, material folding structure 40 clamps auxiliary material 20 again, and hitch structure 14 unclamps auxiliary material 20, and returns back to initial position, continues Aforesaid operations process.

It in some embodiments, further include multiple clamping elements 50, clamping element 50 works asynchronously and hands over hitch structure 14 Mistake work.

In this way, clamping element 50 and material folding structure 40 work asynchronously, clamped when hitch structure 14 unclamps auxiliary material 20 auxiliary Material 20 guarantees that auxiliary material 20 remains suitable tensioning degree.

To sum up, the working principle of the bag making point valve gear 100 in the utility model embodiment approximately as:

Brace and connecting rod framework work, drives hitch structure 14 to do horizontal reciprocating movement, and hitch structure 14 is by auxiliary material 20 from putting It is pulled out on material roller 12, auxiliary material 20 is driven to advance, material folding structure 40 and clamping element 50 work asynchronously, and cooperate hitch structure 14, are leading Guiding structure 14, which clamps when auxiliary material 20 is advanced, unclamps auxiliary material 20, unclamps auxiliary material 20 in hitch structure 14 and is returned to initialization position Auxiliary material 20 is clamped when setting；

The multiple slewing rollers of pile warp after auxiliary material 20 is discharged from emptying roller 12 form roll change surplus, it can be achieved that not shutting down replacement The effect that auxiliary material is volume 20；

Auxiliary material 20 is pulled into press material structure 16 through hitch structure 14, and press material structure 16 presses to auxiliary material 20 on major ingredient, It cuts structure 18 and cuts off auxiliary material 20, stationary distribution is on major ingredient with making 20 discontinuous of auxiliary material.
