The working principle of the invention is as follows:

before the invention starts to work, a worker firstly fixes one end part of the rubber strip ring 111 on the rubber strip 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 vertically clamp the end part of the rubber strip ring 111, and then the worker shifts the clutch handle 71 to a transmission joint slot position, so that the clutch transmission bevel gear 78 is engaged with the fourth bevel gear 472 for transmission, and the transmission of the driving mechanism and the nail feeding mechanism 4 is realized.

The worker then starts the entire drawing pin sheathing machine and the drawing pin vibratory feed tray 13 begins to vibrate the output drawing pins 9 to feed the pin mechanism 4. The driving motor 2 starts to drive the first belt pulley 922 to rotate, and then drives the second belt 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 double bevel gear transmission assembly 97 to rotate, and the third output gear 972 is in meshing transmission with the third bevel gear 77, so as to drive the clutch transmission bevel gear 78 and the fourth bevel gear 472 to rotate.

Meanwhile, the first output gear drives the first bevel gear 38 to rotate, so as to drive the first horizontal rotating shaft 36 to rotate, the first horizontal rotating shaft 36 drives the curved cam 37 and the die advance driving cam 39 to rotate (the punching and trimming die 2 is in a die closing state at this time), and the die advance 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 close the die downwards, the punching and trimming die 2 punches and cuts the adhesive tape, the upper die plate 227 and the lower die plate 231 clamp the adhesive tape up and down, and the adhesive tape is driven to move backwards under the pushing of the die advancing driving cam 39, so that the operations of punching, cutting, feeding and the like are realized.

Meanwhile, the fourth bevel gear 472 drives the driving rotating shaft 471 to rotate, so as to drive the staple feeding driving gear, the unlocking cam 474 and the staple feeding rotating disc to rotate, the staple pushing groove of the staple feeding rotating disc pushes the staple to move along the circular staple feeding guide slit, the staple feeding driving gear 473 and the unlocking cam 474 rotate once, the staple feeding driven gear 475 only rotates one tooth at a time, and the staple feeding rotating disc 42 only rotates one angle of the staple pushing groove at a time, so that the staple feeding rotating disc 42 only feeds one staple 9 at a time. When the staple feeding dial 42 feeds the drawing staple 9 to the staple drop through hole 491, the locking teeth 433 are kept engaged with the staple feeding follower gear 475, so that the staple feeding follower gear 475 cannot rotate, thereby facilitating the nailing by the nailing mechanism 5. Meanwhile, the former clamp pushing plate 420 pushes the rear ends of the left and right support arms 493 and 492 to separate, the front ends of the left and right support arms 493 and 492 are closed, and the drawing pin 9 is pushed onto the left and right support arms 493 and 492 by the pin pushing groove 421. When the front clamp plate 420 is separated from the rear ends of the left and right supporting clamp arms 493 and 492, the rear ends of the left and right supporting clamp arms 493 and 492 are closed, the front ends of the left and right supporting clamp arms 493 and 492 are separated, the drawing pins on the front ends of the left and right supporting clamp arms 493 and 492 naturally fall into the drawing pin falling through holes 491, the drawing pin falling guide heads 46 guide the drawing pins to fall, in the process, the drawing pins cannot be inclined or inclined reversely, the drawing pins are guided by the drawing pin guiding holes, and therefore the drawing pins cannot be inclined by a nailing rod.

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, meanwhile, the locking buckle plate 54 is pushed downwards to enable the locking buckle plate 54 to rotate out of the limit buckle groove 562, the inner end of the locking buckle plate 54 is disengaged from the limit buckle groove 562, so that the sliding block 56 is unlocked, the sliding block 56 can drive the nailing rod 52 to slide downwards, and accordingly, the drawing nails conveyed by the nail feeding mechanism are nailed on the nail holes 81 of the adhesive tape. After the parts complete their respective work, they are returned to their initial positions ready for the next nailing.

In cycles, the present invention repeats the above steps, thereby driving a plurality of drawing pins onto the strip. When the quantity of the drawing nails on the adhesive tape reaches the set quantity, the counter transmits a signal to the control device, the control device starts the electromagnetic valve, the valve rod of the electromagnetic valve extends, the push 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 under the sliding block, the sliding block drives the nailing rod to downwards drive the rotating block to downwards press the rotating block while downwards nailing, and the lifting sliding block moves downwards so that the lifting sliding block drives the slitting knife assembly to downwards cut off the adhesive tape. When the user is binding on giving the nailer, as long as with the adhesive tape dress that above-mentioned nail has a plurality of thumbtacks on the nailer, alright realize a plurality of thumbtacks of disposable installation to improved the binding efficiency of nailer, the nail of ann moreover is very convenient, swift.
