By adopting the technical scheme, the specific working process is as follows:
firstly, the cylinder conveying mechanism 3 and the stabilizer bar conveying mechanism 1 respectively send a first cylinder and a first stabilizer bar to a first combining station: the cylinder 306 drives the transposition member 302 at the bottom of the lower barrel bucket 301, the transposition member 302 drives the discharge port 307 to reciprocate and switch to the state A, the first barrel receiving groove 3041 correspondingly receives a first barrel falling from the discharge port 307 of the lower barrel bucket, and the pushing barrel member 308 reciprocates under the driving of the linear sliding table 303 to push the first barrel to move towards the tape winding mechanism 2; the first rod-feeding driving part 103 bears the first stabilizer rod and makes linear reciprocating motion to drive the first stabilizer rod to move towards the adhesive tape winding mechanism 2; the head end of the first stabilizer bar and the tail of the first cylinder body are close to each other in parallel at a first combining station; the free end of the adhesive tape roll is manually bonded to the joint of the first cylinder and the first stabilizer bar. The operation state of the apparatus at this time is defined as an initial state.
Then, under the action of the tape winding gear 202, the tape roll 201 revolves around the first and second joining stations, and during the revolution, the tape roll 201 with the free end fixed rotates around the rotation shaft 206 and is unwound. In the process, the adhesive tape roll revolves for at least a half of a circle, and of course, the adhesive tape roll can rotate for one circle, two circles or more.
Then, the cylinder conveying mechanism 3 and the stabilizer bar conveying mechanism 1 respectively feed a second cylinder and a second stabilizer bar into a second combining station: when the shifting unit 302 drives the discharge port 307 to reciprocate and switch to the state B, the second barrel receiving groove 3042 correspondingly receives the second barrel falling from the discharge port 307 of the lower barrel hopper, and the barrel pushing unit 308 is driven by the linear sliding table 303 to reciprocate to push the second barrel to move toward the tape winding mechanism 2; the second rod-feeding driving part 104 bears the second stabilizer rod and linearly reciprocates to drive the second stabilizer rod to move towards the tape winding mechanism 2; the head end of the second stabilizer bar and the tail of the second cylinder body are close to each other in parallel at a second combination station.
Then, the tape roll 201 continues to revolve at a certain angle, and when the tape is adhered to the joint portion of the second cylinder and the second stabilizer bar, the upper cutter 207 moves from top to bottom to cut the tape.
At this time, the first cylinder and the first stabilizer bar are bound, and the first rod driving member 103 drives the connected first stabilizer bar and the first cylinder to integrally return when being reset
Meanwhile, the free end of the cut adhesive tape is transferred to the joint of the second cylinder and the second stabilizer bar, the adhesive tape roll 201 continues to revolve, and the adhesive tape is wound on the joint of the second cylinder and the second stabilizer bar along with revolution and is bound and connected because the first joint station does not have the cylinder and the stabilizer bar at the moment.
