The front-end material control cylinder 204b and the rear-end material control cylinder 204c are respectively connected to a front-end material control rod 204d and a rear-end material control rod 204e. Five products b are output at a time. Each time they are output, the front-end material control rod 204d and the rear-end material control rod 204e are first controlled to descend. The front-end material control rod 204d is against the front end of the first product b, and the rear-end material control rod 204e presses down the sixth product b. Figure 3 As shown, the front end material control rod 204d is then lifted, and five products b are output at a time. The front end material control rod 204d is then lowered and the rear end material control rod 204e is lifted, and the products b are arranged and fall. The rear end material control rod 204e is then lowered to press down the sixth product b. The aforementioned steps are repeated to realize the automatic counting and output of product b.

A push-out assembly for pushing out the material tube a is arranged below the low-position tube placement seat 302. The push-out assembly includes a tube push block 305 driven by a tube push cylinder 304. The tube push block 305 can extend into the low-position tube placement seat 302 to push the material tube a upward. A return tube assembly for returning the material tube a is arranged below the high-position tube placement seat 303. The return tube assembly includes a return tube telescopic cylinder 306, a return tube lifting cylinder 307 connected to the return tube telescopic cylinder 306, and a return tube column 308 connected to the return tube lifting cylinder 307. The return tube column 308 can be telescopic and can be lifted and lowered. The return tube column 308 can extend into the high-position tube placement seat 303 to push the material tube a back to its original position.

[0040] A tube pulling assembly is provided on the outer side of the high-position tube holder 303, and the tube pulling assembly is used to open the tube opening of the material tube a. Figure 5 , Figure 6 The tube drawing assembly includes a draw hook 310 driven by a tube drawing lifting cylinder 309 and a tube mouth pressing block 311 arranged below the draw hook 310 to cooperate with pressing the material tube a.

[0041] When product b is loaded in material tube a, material tube a is placed between the low-position tube holder 302 and the high-position tube holder 303, and the tube push cylinder 304 is activated first, driving the tube push block 305 to extend into the low-position tube holder 302, pushing out material tube a, and the other end of material tube a passes through the high-position tube holder 303 and extends to the feeding mechanism 2. After material tube a is in place, the draw hook 310 and the tube mouth pressing block 311 are both located in the tube mouth, and the tube mouth of material tube a is pressed by the tube mouth pressing block 311, and then the tube draw lifting cylinder 309 is activated to drive the draw hook 310 to The return tube column 308 moves upward and pulls the tube mouth upward to open the tube mouth, and then the feeding mechanism 2 feeds the product b into the material tube a. After the material tube a is filled with material, the return tube telescopic cylinder 306 is actuated to drive the return tube column 308 to extend, and then the return tube lifting cylinder 307 is actuated to drive the return tube column 308 to rise to one side of the tube mouth of the material tube a, and the return tube telescopic cylinder 306 then drives the return tube column 308 to retract, so that the return tube column 308 moves to abut against the end of the material tube a, and drives the material tube a to move and send it back to its original position, and then the return tube column 308 is reset.

[0042] Reference Figure 1 , Figure 7A material tube push plate assembly is provided on one side of the base plate 301. The material tube push plate assembly includes a material tube push plate 313 driven by a material tube push cylinder 312, and two slide bars 314 connected to the material tube push plate 313. Each end of the slide bar 314 is elastically mounted with a tilting block 315 through a spring. One end of the tilting block 315 is rotatably connected to the slide bar 314, and the other end is in a tilted state. A guide positioning assembly for guiding the movement of the material tube a is provided on the other side of the base plate 301. The guide positioning assembly includes a relatively arranged low-position positioning plate 316 and a high-position limiting plate 317. The low-position positioning plate 316 is arranged on one side of the low-position tube holder 302, and the high-position limiting plate 317 is arranged on one side of the high-position tube holder 303. When the material tube a is pushed out, one end of the material tube a slides against the low-position positioning plate 316, and the other end is located below the high-position limiting plate 317. A positioning clamp 318 is provided between the low positioning plate 316 and the high limiting plate 317 near the high limiting plate 317. Figure 4 The positioning jaw 318 is driven to open and close by the jaw cylinder 319, and the jaw cylinder 319 is connected to the upper cylinder 320, so that the positioning jaw 318 can be lifted up and down. The material tube push plate 313 is also provided with an avoidance notch 313a for avoiding the positioning jaw 318, so that the positioning jaw 318 can clamp and fix the material tube a.

[0043] After the material tube a is loaded with product b between the low-position tube placement seat 302 and the high-position tube placement seat 303, the material tube pushing cylinder 312 drives the material tube pushing plate 313 to extend, and the two tilting blocks 315 are driven to extend synchronously, and the tilted ends of the tilting blocks 315 push the material tube a at the nailing mechanism 4 into the receiving hopper 5 first; at the same time, the material tube pushing plate 313 will push the material tube a in the tube placement seat to the nailing mechanism 4. After the material tube a is sent to the nailing mechanism 4, the low-position positioning plate 316 is against one end of the material tube a, and the high-position limiting plate 317 presses the other end of the material tube a. Then the upper cylinder 320 drives the positioning jaw 318 to rise, and the positioning jaw 318 passes through the avoidance recess 313a on the material tube pushing plate 313, and then the jaw cylinder 319 drives the positioning jaw 318 to close, clamping and fixing the material tube a. After the material tube a is fixed, it is ready for nailing. Then the material tube pushing plate 313 can return, and when the lifting block 315 returns synchronously, the fixed material tube a applies downward pressure to the lifting block 315, and the lifting block 315 can be automatically compressed back by the spring and smoothly slide out from under the material tube a. The material tube pushing plate 313, the slide bar 314, and the lifting block 315 are reset to prepare for the next tube pushing action.

[0044] Reference Figure 7 , Figure 8The low-position tube holder 302 is also provided with a partition block 321 for separating the upper and lower material tubes a. The partition block 321 is driven to extend and retract by the tube-dropping telescopic cylinder 322. One end of the material tube a in the low-position tube holder 302 is plugged with a pin to prevent leakage when loading product b. One end of the material tube a in the high-position tube holder 303 is used to load product b. The partition block 321 in the low-position tube holder 302 can separate the ends of the upper and lower material tubes a plugged with pins from each other to prevent mutual interference caused by the contact of the pins when the material tube a moves. The other ends of the upper and lower material tubes a are smooth, and the upper and lower stacking will not cause mutual interference. When the tube-dropping telescopic cylinder 322 drives the partition block 321 to retract and withdraw from the low-position tube holder 302, the upper material tube a can fall down for loading.

[0045] Reference Fig. 9 , Fig.10 , Fig.11 The nail mechanism 4 includes a vibrating loading tray 401, the output end of the vibrating loading tray 401 is connected to a feed track 402, and nail full material detection sensors 403 are respectively provided on the upper and lower sides of the input end of the feed track 402, and the output end of the feed track 402 is connected to a suction assembly, the suction assembly includes a nail pushing block 405 driven by a pushing block telescopic cylinder 404, and a nail suction block 406 connected to the nail pushing block 405, the nail pushing block 405 is slidably fitted with the output end of the feed track 402, and a vacuum suction hole is provided on the nail suction block 406, when the nail suction block 406 carries the nail c, the nail pushing block 405 can block the output end of the feed track 402 to prevent the nail c in the feed track 402 from falling out.

[0046] A nail clamping claw assembly is provided on one side of the material suction assembly, and the nail clamping claw assembly includes a nail clamping claw 407, a rotating cylinder 408 connected to the nail clamping claw 407, and a nail telescopic cylinder 409 connected to the rotating cylinder 408. Nail material detection sensors 410 are also provided on the upper and lower sides of the nail clamping claw 407, respectively.

[0047] The material tube a loaded with product b is pushed to the nailing mechanism 4 and clamped and fixed, waiting for the nailing. The vibrating loading tray 401 sends the nail c into the feeding track 402. After the nail full material detection sensor 403 receives the full material signal, the vibrating loading tray 401 stops; the nail c in the feeding track 402 falls to the nail suction block 406 and is vacuum-absorbed. Then the push block telescopic cylinder 404 is actuated to move the nail suction block 406 to the nail clamping claw 407. The nail material detection sensor 410 detects Is there a pin c on the pin sucking block 406? If no pin c is detected, the pin sucking block 406 is retracted to repeat the action of sucking the pin. After the pin is detected, the pin clamping claw 407 clamps the pin c, and the pin sucking block 406 is retracted at the same time. Then the rotating cylinder 408 is actuated to rotate the pin c 90 degrees. Then the pin telescopic cylinder 409 is actuated to smoothly send the pin c into the mouth of the material tube a, and then rotate it 90 degrees again in the mouth of the tube to make the pin c snap into the snap-in a0 of the material tube a, completing the assembly of the pin c. After the assembly is completed, the pin clamping claw 407 is opened, the pin telescopic cylinder 409 is retracted, the pin sucking block 406 sucks the pin c again and moves to the pin clamping claw 407 to repeat the above pinning action, and the next material tube a is pinned. The material tube a that has been pinned is pushed into the receiving hopper 5 for collection.
