Referring to fig. 4, the transmission assembly 225 includes a driving gear 2251 provided on a driving shaft 2231, a driven gear 2252 provided on a driven shaft 2241, and a timing belt 2253 connecting the driven gear 2252 and the driving gear 2251.

The principle of operation of collating mechanism 22 is as follows:

when the tidying motor 2232 rotates, the driving shaft 2231 and the driving gear 2251 rotate along with the tidying motor 2232, the driving gear 2251 drives the driven gear 2252 and the driven shaft 2241 to rotate simultaneously through the synchronous belt 2253, and at this time, the lower tidying cam 2233 on the driving shaft 2231 and the upper tidying cam 2242 on the driven shaft 2241 rotate synchronously. Due to the fact that friction force between the to-be-processed pipes after stacking is large, and due to the material, the to-be-processed pipes at the bottom layer after stacking deform, and the to-be-processed pipes are difficult to roll downwards along the feeding channel 2223. In addition, because treat that the processing pipe does not scald the operation of connecing to both ends before putting into the machine, treat that the plastic strip that the processing pipe both ends loosened can cause respectively to treat nonparallel between the processing pipe, treat that the tip butt of processing pipe unevenness can increase the resistance that rolls in spacing riser 211 to the influence rolls. Lower arrangement cam 2233 and last arrangement cam 2242 take place to rotate in step, can disturb the tube stack, can upwards prop up the tube stack simultaneously for the interaction force between each other is littleer when the tube stack falls, and the gliding or the roll of the pipe of conveniently waiting to process falls. In actual operation, the pipes to be processed are stacked into an arch shape, and the rotation path of the single cam cannot interfere with the arch shape, so that the pipes to be processed cannot fall down, and therefore the lower arranging cam 2233 and the upper arranging cam 2242 need to be matched to act to destroy the formation of the arch shape, and the pipes to be processed can conveniently fall down.

The overall working principle of the pipe penetrating device 6 is as follows:

first, the pulling mechanism 61 performs pre-threading positioning of the threading rod 611. The clamping mechanism 4 clamps the pipe to be processed in advance, the traction motor 6151 drives the screw 6152 to rotate, the screw 6152 drives the sliding block 614 and the penetrating rod 611 to move towards the pipe to be processed, at the moment, the clamping groove 616 at the end of the penetrating rod 611 is clamped on the side wall of the pipe to be processed, and the pipe to be processed is pushed to move to a preset position. At this time, the clamping cylinder 42 of the clamping mechanism 4 is switched to high-pressure operation, the clamping block 43 is pushed to completely clamp the pipe to be processed, and the hot-pressing operation is performed.

Then, the bayonet mechanism 63 bayonet-fixes the penetrating rod 611 and the pipe to be processed. After finishing the ironing connection, the bayonet motor 631 works to drive the penetrating rod 611 to rotate by 90 degrees, and at the moment, the clamping groove 616 twists off the plastic strip clamped inside the pipe to be processed.

Next, the upper ejection cylinder 622 of the lifting mechanism 62 pushes the ejection block 621, so that the pulling mechanism 61 and the bayonet mechanism 63 are integrally lifted up, so that the piercing rod 611 coincides with the axis of the pipe to be processed. Then the traction motor 6151 works to drive the screw 6152 to rotate so as to drive the penetrating rod 611 to penetrate into the pipe to be processed. At this time, the clamping groove 616 at the end of the through rod 611 clamps the twisted plastic strip of the pipe to be processed and moves until the end of the through rod 611 passes through the pipe to be processed and reaches a predetermined position. The end part of the plastic strip is exposed out of the pipe to be processed, so that the pipe to be processed is convenient for people to tear the plastic strip when in use.

After reaching the preset position, the traction motor 6151 rotates reversely to make the penetrating rod 611 withdraw, and simultaneously the bayonet motor 631 works to drive the penetrating rod 611 to rotate so as to untie the spiral of the plastic strip in the pipe to be processed. In addition, the penetrating rod 611 rotates when retracting, and the resetting error of the penetrating rod 611 is reduced through multiple turns, so that the clamping groove 616 after resetting is kept in a horizontal state.

Referring to fig. 8, the cutting mechanism 7 is located between the ironing mechanism 5 and the clamping mechanism 4, and includes a fixed frame 71 disposed on the workbench 1, a cutting cylinder 72 hinged to the fixed frame 71 and disposed downward, a driving shear rod 73 hinged to a piston rod of the cutting cylinder 72, and a driven shear rod 74 hinged to the workbench 1, wherein middle portions of the driving shear rod 73 and the driven shear rod 74 are hinged to each other and are matched with each other to rotate in a vertical plane. The end of the driving shear rod 73 far away from the shearing cylinder 72 is provided with a blade 75, the end of the driven shear rod 74 far away from the workbench 1 is also provided with a blade 75, and the blades 75 of the driving shear rod 73 and the driven shear rod 74 are arranged oppositely. The shearing cylinder 72 pushes or pulls the driving shear bar 73 so that the cutting edge 75 of the driving shear bar 73 and the cutting edge 75 of the driven shear bar 74 abut against or separate from each other.

The overall working principle of the shearing mechanism 7 is as follows:

after the penetrating rod 611 penetrates, a part of the plastic strip is taken out of the pipe to be processed, and after the penetrating rod 611 is reset, the part of the plastic strip is left outside the pipe to be processed. At this time, the cutting cylinder 72 pushes the driving shear bar 73, and the cutting edge 75 of the driving shear bar 73 and the cutting edge 75 of the driven shear bar 74 abut against each other, thereby cutting the plastic strip exposing the pipe to be processed.

After the plastic strip exposing the pipe to be processed is cut off, the holding mechanism 4 and the supporting mechanism 3 sequentially release the support of the pipe to be processed, and the pipe to be processed and the cut plastic strip fall into the charging chute 11.

Example two:

the jig trays 233 are divided into two groups, an outside group and an inside group, each of which includes two jig trays 233. The inner group is located below the feeding path 2223, and each of the jig trays 233 is keyed to the rotational shaft 231. Wherein the notch 236 of the outer set of gripper pads 233 is smaller than the inner set of gripper pads 233 and is oppositely disposed.

The overall working principle is as follows: the notch 236 of the outer group of clamp discs 233 is matched with a small-sized pipe to be machined, and the notch 236 of the inner group of clamp discs 233 is matched with a large-sized pipe to be machined. When a small-sized pipe to be machined is machined, the outer group of clamp discs 233 slide along the rotating shaft 231 to the lower side of the feeding channel 2223, and in the present embodiment, the outer group of clamp discs 233 abut against the inner group of clamp discs 233, and at this time, the pipe to be machined can fall onto the outer group of clamp discs 233 with the small notches 236. When a large-sized pipe to be machined is machined, the outer group of jig trays 233 is moved along the rotation shaft 231 away from the lower side of the feeding path 2223, and at this time, the pipe to be machined can fall onto the inner group of jig trays 233 having the larger notches 236. So that the material conveying mechanism 23 can adapt to pipes to be processed with different specifications.

The above-mentioned embodiments are merely illustrative of the present invention, and are not intended to limit the present invention, and those skilled in the art can make modifications of the present embodiments without inventive contribution as required after reading the present specification, but all the embodiments are protected by patent law within the scope of the present invention.
