50, fourth link 14 close to limited block 30, knock pin 20 close to link assembly 10 one end and fourth link 14 against.
The both ends of second connecting rod 12 are hinged with first connecting rod 11 and third connecting rod 13 respectively, the both ends difference of third connecting rod 13
Hinged with second connecting rod 12 and fourth link 14, the both ends of fourth link 14 are cut with scissors with third connecting rod 13 and first connecting rod 11 respectively
It connects, first connecting rod 11 is arranged in parallel with third connecting rod 13, and second connecting rod 12 is arranged in parallel with fourth link 14.
One connecting plate 90 is installed, one end of connecting plate 90 connects with second between second connecting rod 12 and the cylinder rod 51 of cylinder 50
Bar 12 is hinged, and the other end and cylinder rod 51 of connecting plate 90 are hinged.
Feeding step pitch control mechanism further includes elastic component 70, and knock pin 20 and elastic component 70 are mounted in limited block 30, bullet
Property part 70 act on and make knock pin 20 that there is the trend that moves towards link assembly 10 on knock pin 20, knock pin 20 is close to connecting rod
One end of component 10 and link assembly 10 against.Mounting hole 80, elastic component 70 and ejection are equipped in limited block 30 in the horizontal direction
Pin 20 is mounted in mounting hole 80.The rest position that the fourth link 14 of knock pin 20 and link assembly 10 abuts each other, which is higher than, to be connected
Fishplate bar 90 and the hinged hinge joint position of second connecting rod 12.Preferably, elastic component can be spring, but not limited to this, it can also be with
It is that can push other elastic components such as elastic slice etc. moved outside knock pin 20.
Referring to Fig. 2, cylinder 50 is ventilated, the cylinder rod of cylinder 50 when feeding step pitch control mechanism is on line state
51 stretch out, and push the movement of link assembly 10 to be located at jacking state by connecting plate 90.Jacking shape is in link assembly 10
When state, knock pin 20 of the fourth link 14 of link assembly 10 on limited block 30, limited block 30 is pressed by fourth link 14
In limited block 30, the spring 70 in knock pin 20 is in compressive state, and knock pin 20 is also at retracted mode.
Fig. 3 and Fig. 4 are please referred to, in 50 stuffiness of cylinder, knock pin 20 is for pushing link assembly 10 from jacking state
Move to decline state.When 50 stuffiness of cylinder, springback in knock pin 20 is ejected knock pin 20, and knock pin 20
Further the fourth link 14 of link assembly 10 is pushed to move right, reached when knock pin 20 pushes fourth link 14 to move right
Certain displacement, such as when the angle of fourth link 14 and limited block 30 being made to be greater than 5 °, link assembly 10 will be acted in own wt
It is lower mobile to off-position, it is final to automatically reset by the own wt of link assembly 10, drop to extreme lower position.
Preferably, the rest position that the fourth link 14 of knock pin 20 and link assembly 10 abuts each other is higher than connecting plate 90
The hinge joint position hinged with second connecting rod 12, such knock pin 20 push the fourth link 14 of link assembly 10 to move right
When, it will be more labor-saving.Specifically, the rest position that the fourth link 14 of knock pin 20 and link assembly 10 abuts each other can be the
The medium position of double leval jib 14, connecting plate 90 and the hinged hinge joint position of second connecting rod 12 can be close to lower die holder 40.

The mounting stability of bar 11, while simplifying the structure of link assembly 10.First connecting rod 11 can also be direct by modes such as welding
It is mounted on lower die holder 40.
Further, first connecting rod 11 is arranged in parallel with third connecting rod 13, and second connecting rod 12 is parallel with fourth link 14
Setting, then 10 hinge joint of link assembly forms parallelogram, biggish stroke is capable of providing during the work time, to expand
The scope of activities of workpiece.
First connecting rod 11 is not limited to be arranged in parallel with third connecting rod 13, can also when guaranteeing device scope of activities, two
Person can have angle appropriate.Similarly, second connecting rod 12 is also not limited to fourth link 14 and is arranged in parallel, and can guarantee to fill
When setting scope of activities, the two can have angle appropriate.
Further, above-mentioned feeding step pitch control mechanism further includes the inductive component 60 for controlling cylinder 50, inductive component 60
It is connected with link assembly 10.When feeding step pitch control mechanism is on line state, the cylinder rod 51 of cylinder 50 stretches out, link assembly
10 drive inductive components 60 rise to operating position, place in the vertical height and the intracavitary conveyer belt of wrapping mold drag of the position
Height of materials it is consistent.When material encounters inductive component 60, inductive component 60 receives signal and sends transmission translator to, motor
Stopping working makes conveyer belt stop motion, and material, which is placed into die cavity, carries out bound edge.Meanwhile inductive component 60 transmits a signal to
The cylinder rod 51 of cylinder 50, cylinder 50 retracts, and link assembly 10 drives inductive component 60 to drop to off-position, under the position
Feeding step pitch control mechanism does not interfere when material transfers out die cavity, it is ensured that material smooth delivery of power goes out die cavity.In this way, passing through sense
Component 60 is answered to detect the contact height of material, and controls connecting rod component 10 and cylinder 50 work, and improve feeding step pitch control mechanism
The property easy to implement to automatically reset.
Specifically, third connecting rod 13 is connected with mounting plate 61, and inductive component 60 is installed on link assembly by mounting plate 61
10.Or fourth link 14 is connected with mounting plate 61, inductive component 60 is installed on link assembly 10 by mounting plate 61.From theory
From, inductive component 60 is not limited to above structure, also may be mounted on any connecting rod, as long as can guarantee material position
?.
In addition to above-mentioned feeding step pitch control mechanism, the present invention also provides a kind of packets including above-mentioned feeding step pitch control mechanism
Side mode.
Further, above-mentioned bound edge is touched as luggage case wrapping mold.
Refer to the prior art for other Each parts of wrapping mold, and details are not described herein.
If common four-bar mechanism is in jacking state and cylinder does not have reverse ventilation, four-bar mechanism is because of center of gravity original
Because jacking state will be kept, decline state can not be automatically reset to.The embodiment of the present invention increases ejection on the basis of original mechanism
Pin is used as automatic reset device, pushes four-bar mechanism by knock pin, can pass through knock pin under the obstructed gaseity of cylinder
So that four-bar mechanism is automatically reset, improves mechanism reliability safety, avoid causing mechanism to damage because of operation error.Moreover, this
The structure of inventive embodiments is simple, compares with common double leval jib component, merely adds reset knock pin；And reliable in action,
Link assembly jacks exhaust hood air inlet and closes, and link assembly can push link assembly automatically multiple in own wt by knock pin
Position.
