In the use, place the orderly panel of range on the bar breach of panel blowing board 1, then arrange in order and adjust, open panel adjusting device 4's tightening bolt, at the inslot back-and-forth movement for the elastic block of horizontal spring adjusting plate 42 front end touches the panel of bottommost, then screws up the tightening bolt.

The spring of adjustable elasticity is connected to the rear end of elastic block, and after spring spanner rotated to the position, with bolt fastening position, the elasticity that just can adjust the spring, rotation angle is big more, and the spring rises tightly more, and vertical gear board 41 plays further spacing effect, prevents that the upper plate material from excessively squinting, makes it neater more that stacks.

The driving motor of the first gear 22 is turned on, the first gears 23 at the two ends synchronously rotate at the same time to drive the chain conveying belt 2 to rotate anticlockwise, at the moment, the push-out block 21 reaches the rightmost side of the plate at the lowest part along with the chain conveying belt 2, and the highest position of the push-out block 21 cannot exceed the highest position of the plate at the lowest part, so that the push-out block 21 only acts on the plate at the lowest part.

The in-process that the ejecting block 21 was gone forward from right side to left side drives the panel of below from right side to left side together, and panel has been pushed away the finished product bench from panel blowing board 1, and the cylinder of the ejector pad 51 of finished product bench starts this moment, promotes the finished product forward for the finished product is arranged in proper order, makes things convenient for the workman to take.

The plate material that is originally the second to last falls to the lowest position under the action of gravity, and the pushing block 21 rotates around the first gear 23 and the second gear 22 along with the chain conveyor belt 2 once again to the right side of the plate material at the lowest position, and performs repeated pushing actions.

Firstly, the spring fastener tape is wound on the feeding barrel 8, the central hole of the feeding barrel 8 is plugged into the roller, and a bearing is arranged between the feeding barrel and the roller, so that the spring fastener tape can rotate relatively, the spring fastener tape on the outermost ring is drawn out and plugged into the space between the first clamping piece 61 and the second clamping piece 62, because the opening block 63 is arranged between the first clamping piece 61 and the second clamping piece 62, the inner space is not easy to deform, the spring fastener tape can conveniently penetrate through the inner space, then the spring fastener tape enters the penetrating cavity, the guide block 7 is fixed on the first clamping piece 61 through screws on two sides, the penetrating cavity is formed by the guide block 7 and the first clamping piece 61, and the penetrating cavity and the spring fastener tape are in clearance fit, so that the spring fastener tape can keep certain linearity and the angle.

The first clamping piece 61 is not fixed, the upper end of the first clamping piece is fixed with the feeding frame 5, and the first clamping piece 61 continuously swings under the conveying acting force of the spring buckle belt to adjust the angle of the first clamping piece, so that the first clamping piece is better matched with the spring buckle belt, the spring buckle belt is prevented from deviating, and the spring buckle belt is prevented from being too tight or too loose.

The spring strap utilizes the weight of self to transport downwards, still set up intermittent type unloading mechanism between feed cylinder 8 and pay-off adjusting device, the last locating lever 92 of this mechanism is motionless all the time, fixed, cylinder 94 starts the back, the cylinder axial upwards contracts, the afterbody and the lower locating lever 91 fixed connection of cylinder axis, consequently lower locating lever 91 is upwards along with the cylinder axis together, lower locating lever 91 is close to last locating lever 92 and forms the closure action, because still wear to be equipped with clearance fit's sliding block 93 on lower locating lever 91, sliding block 93 has played limiting displacement, it just stops the closure to go up the upper and lower both ends that upper locating lever 92 and lower locating lever 91 closed sliding block 93 at most.

The size of the closed gap at this moment is the thickness of the sliding block 93, and the thickness is the same as that of the spring fastener belt, so the spring fastener belt can be just clamped, the spring fastener belt is enabled not to slide downwards along the C-shaped feeding frame 5 any more, after the interval of one-second closing time, the air cylinder is closed, the air cylinder shaft is extended downwards, the upper positioning rod 92 and the lower positioning rod 91 are separated again, at this moment, the spring fastener belt slides downwards along the C-shaped feeding frame 5 under the action of gravity, after the interval of one-second opening time, the air cylinder continues to be started to be closed, at this moment, the sliding quantity is just the length of one spring fastener, so the feeding length is accurate, the efficiency is high, and.

In the conveying process, in order to prevent the spring buckle belt from retracting when the buckle belt is buckled, the one-way gear 14 on the connecting rod I13 is designed and manufactured, the one-way gear 14 is a helical gear, helical teeth of the helical gear are clamped into holes between every two spring buckles, when the spring buckle belt automatically moves downwards under the action of gravity, the one-way gear 14 and a fixed shaft on the connecting rod I13 rotate relatively, the one-way gear 14 rotates anticlockwise by the angle of one tooth, and normal blanking of the spring buckle belt is not influenced.

In the process of making a button, impact force is inevitably generated on the spring buckle belt, the spring buckle belt can possibly be reversed, once the spring buckle belt backs up, the one-way bearing of the one-way gear 14 plays a role and cannot rotate clockwise, the one-way bearing can freely rotate in one direction and is locked in the other direction, a metal shell of the one-way bearing comprises a plurality of rolling shafts, rolling needles or rolling balls, and the rolling seats (cavities) of the one-way bearing are shaped so that the one-way bearing can only roll in one direction, and great resistance force can be generated in the other direction.

Once the one-way gear 14 cannot be rotated, the helical teeth are engaged in the holes between two spring buckles, and a relative force is generated to prevent the spring buckles from retracting.

In the path that the plate advances towards the punch from the right to the left, the pressing position control mechanism 30 is firstly contacted, when the plate passes through the front of the baffle plate 301, the plate presses one end of the second connecting rod 302, one end of the second connecting rod 302 is exposed out of the opening, and rotates clockwise around the hinge shaft 304 after being pressed and retracts into the opening, the plate can continuously and smoothly pass through, at the moment, the gasket at the other end of the second connecting rod 302 also rotates clockwise, the plectrum of the travel switch 303 is pressed and driven to rotate, the travel switch 303 is opened, the travel switch 303 is connected with the PLC control unit of the punch, the pressing time after the power is turned on is input in the PLC control unit in advance, namely, the punch is pressed down at an interval of 1.5 seconds by taking the opening machine as the initial time, and the longer the interval of time is, the farther the first punched spring fastener is away from the edge of the plate under the condition that the, the closer the time interval, the closer the first snap fastener is struck to the edge of the sheet material.

Regarding the distance control between the subsequent two spring buckles, the pressing time of the punch at intervals is determined, and the pressing time is also input into the PLC control unit in advance.

The punch 40 includes a flat pressing portion acting on the upper ends of the two climbers, and an insert portion inserted into a hole formed between two climbers.

The protection scope of the present invention includes but is not limited to the above embodiments, the protection scope of the present invention is subject to the claims, and any replacement, deformation, and improvement that can be easily conceived by those skilled in the art made by the present technology all fall into the protection scope of the present invention.
