Under the action of the elastic force of the fifth reset spring, the inner end of the locking buckle plate is kept in a state of being screwed into the limiting buckle groove so as to lock the sliding block and prevent the sliding block from sliding downwards. When the nailing mechanism nailing, the driving and unlocking gear rotates, the driving and unlocking gear drives the sliding block to slide downwards and toggle the locking buckle plate simultaneously so that the locking buckle plate rotates out of the limit buckle groove (the fifth reset spring is lengthened), the inner end of the locking buckle plate is tripped with the limit buckle groove, and therefore the sliding block is unlocked, and can drive the nailing rod to slide downwards and nailing (the jacking reset spring is compressed). When the nailing mechanism finishes one nailing operation, the sliding block rises and resets, the inner end of the locking buckle plate is screwed into the limiting buckle groove again, the sliding block is prevented from sliding downwards, and the locking buckle plate is stirred again by the driving and unlocking gear.

The present invention can be further improved as follows.

When the sliding block drives the nailing rod to downwards nailing, the nailing rod drives the drawing pin into the nail hole of the adhesive tape, at the moment, the sixth reset spring is compressed by the nailing rod, the drawing pin is already driven in place, the nail cap of the drawing pin is tightly attached to the adhesive tape, the nailing rod is abutted to the nail cap of the drawing pin and does not descend any more, but the driving and unlocking gears can continuously drive the sliding block to downwards move, the sliding block can still continuously descend (the upper end of the nailing rod and the locking nut are separated from the top of the sliding block), and due to the reserved distance between the limiting convex ring and the bottom of the sliding block, the sliding block can descend by the reserved distance again, so that the nailing rod does not continuously descend to drive the drawing pin even if the sliding block descends again, and the nailing rod is prevented from damaging the drawing pin. The limiting convex ring can limit the sliding block to continuously descend, so that the sixth return spring is protected from being crushed.

Because the thickness of the nail caps of different drawing pins is different, if the length of the nailing rod and the nailing stroke of the nailing rod are fixed, namely, the nailing rod is fixedly connected with the sliding block, the depth of the nail holes driven by the drawing pins with different nail cap thicknesses is not guaranteed to be the same, and the nail holes on the adhesive tape can not be driven by the drawing pins with different nail cap thicknesses well. The same nailing mechanism is used for nailing a drawing pin with a thinner pin cap and a drawing pin with a thicker pin cap, and if the pin cap of the drawing pin is thinner, the length of the nailing rod and the nailing stroke of the nailing rod are enough to drive the drawing pin into a nail hole, so that the drawing pin with a thin pin cap can be driven into place by the nailing mechanism. If the nail cap of the drawing pin is thicker, the length of the nailing rod and the nailing stroke thereof are relatively longer, and the nailing rod can damage the drawing pin, but because the nailing rod and the sliding block are movably connected up and down, the nailing rod can shrink upwards, the nailing rod can realize the purpose of driving the drawing pins with different nail cap thicknesses into nail holes on the adhesive tape, and can prevent the nailing rod from damaging the whole drawing pin. Therefore, the nailing mechanism disclosed by the invention can be suitable for nailing of drawing nails with different nail cap thicknesses, and can be well nailed on the nail holes of the adhesive tape.

In contrast, when there is no adhesive tape on the adhesive tape ring fixing wheel, that is, when there is no adhesive tape on the adhesive tape feeding guide groove 125, the inner end of the detection pressing plate 123 falls into the detection yielding hole 122 and approaches or abuts against the proximity switch 124, then the proximity switch 124 acts, the proximity switch 124 sends an electrical signal of "shortage" to the control device, and the control device controls the whole drawing pin strip sleeving machine to stop.

The working principle of the invention is as follows: before the invention starts to work, a worker firstly fixes one end part of the adhesive tape ring 111 on the adhesive tape ring fixing wheel 6 on the punching and trimming die 2, namely the upper die plate and the lower die plate of the punching and trimming die 2 clamp the end part of the adhesive tape ring 111 up and down, and then the worker dials the clutch handle 71 to a transmission joint slot position, so that the clutch transmission bevel gear 78 and the fourth bevel gear 472 are meshed for transmission, and the driving mechanism and the nailing mechanism 4 are driven.

Then, the worker starts the whole drawing pin strip sleeving machine, and the drawing pin vibration feeding tray 13 starts to vibrate and output drawing pins 9 to the feeding mechanism 4. The driving motor 2 starts to drive the first pulley 922 to rotate, and then drives the second pulley and the pinion 93 to rotate, the pinion 93 drives the large gear 94 to rotate, the large gear 94 drives the transmission main shaft 942 to rotate, the transmission main shaft 942 drives the fifth bevel gear 941 and the sixth bevel gear 940 to rotate, and the fifth bevel gear 941 drives the first output gear 951 of the first double bevel gear transmission assembly 95 and the second output gear 963 of the second double bevel gear transmission assembly 96 to rotate. The sixth bevel gear 940 drives the third input gear 972 of the third dual bevel gear assembly 97 to rotate, and the third output gear 972 is in meshed transmission with the third bevel gear 77, thereby driving the clutch transmission bevel gear 78 and the fourth bevel gear 472 to rotate.

At the same time, the first output gear drives the first bevel gear 38 to rotate, so as to drive the first horizontal rotating shaft 36 to rotate, and the first horizontal rotating shaft 36 drives the curved cam 37 and the die forward driving cam 39 to rotate (the punching and trimming die 2 is in a die clamping state at this time), and the die forward driving cam 39 pushes the punching and trimming die 2 to move backwards. Meanwhile, the transmission main shaft 942 drives the driving press roller 21 to rotate, the driving press roller 21 drives the upper die to downwards clamp, the punching and trimming die 2 punches and trims the adhesive tape, the upper die plate 227 and the lower die plate 231 vertically clamp the adhesive tape, and the adhesive tape is driven by the die advancing driving cam 39 to move backwards, so that the operations of punching, trimming, feeding and the like are realized. Meanwhile, the fourth bevel gear 472 drives the driving shaft 471 to rotate, and then drives the staple feeding driving gear, the unlocking cam 474 and the staple feeding turntable to rotate, and the staple pushing grooves of the staple feeding turntable push the staples to move along the circular staple feeding guide staples, so that the staple feeding driving gear 473 and the unlocking cam 474 rotate one circle each time, the staple feeding driven gear 475 rotates only one tooth each time, and the staple feeding turntable 42 rotates only one angle of the staple pushing grooves each time, and therefore the staple feeding turntable 42 only feeds one staple 9 each time. When the staple feeding dial 42 conveys the staple 9 to the staple falling through hole 491, the lock tooth 433 is kept engaged with the staple feeding driven gear 475, and therefore the staple feeding driven gear 475 cannot rotate, thereby facilitating the stapling by the stapling mechanism 5. At the same time, the front pusher plate 420 pushes the rear ends of the left and right support arms 493, 492 apart, the front ends of the left and right support arms 493, 492 are closed, and the pushpin 9 is pushed onto the left and right support arms 493, 492 by the staple pushing groove 421. When the front pusher plate 420 is disengaged from the rear ends of the left and right support arms 493, 492, the rear ends of the left and right support arms 493, 492 are closed, and the front ends of the left and right support arms 493, 492 are separated, so that the pins on the front ends of the left and right support arms 493, 492 naturally fall into the pin through holes 491, and then the pin guide head 46 guides the pins to fall, during which the pins do not tilt or skew upside down, and the pin guide holes guide the pins, thereby ensuring that the pin rod does not skew the pins.

Meanwhile, the second output gear of the second double bevel gear transmission assembly 96 drives the second bevel gear 53 to rotate, the second bevel gear 53 drives the driving and unlocking gear 53 to rotate, the driving and unlocking teeth 531 of the driving and unlocking gear 53 drive the sliding block 56 to slide downwards, the locking buckle plate 54 is simultaneously shifted downwards so that the locking buckle plate 54 rotates out of the limit buckle groove 562, the inner end of the locking buckle plate 54 is tripped from the limit buckle groove 562, the sliding block 56 is unlocked, the sliding block 56 can drive the nailing rod 52 to slide downwards, and a thumbtack conveyed by the nailing mechanism is driven on the tack hole 81 of the adhesive tape. After the parts have completed their respective work, they are returned to their original positions and are ready for the next nailing.

The present invention repeats the above steps, repeating the steps, thereby driving a plurality of pins onto the strip. When the number of the thumbtacks on the adhesive tapes reaches the set number, the counter transmits a signal to the control device, the control device starts the electromagnetic valve, the valve rod of the electromagnetic valve stretches, the pushing wheel starts to push the upper end of the rotating block to rotate (the seventh reset spring is compressed), the upper end of the rotating block rotates to be right below the sliding block, at the moment, the sliding block drives the nailing rod to downwards nailing, meanwhile, the rotating block is downwards pressed, and the lifting sliding block downwards moves, so that the lifting sliding block drives the slitting knife assembly to downwards cut off the adhesive tapes. When a user installs nails on the nailing machine, the plurality of thumbnails can be installed at one time only by installing the adhesive tape with the plurality of thumbnails on the nailing machine, so that the nailing efficiency of the nailing machine is improved, and the nailing is very convenient and quick.
