At this time, the baffle 822 and the bottom plate 821 are in a non-parallel state, and a certain angle is formed between the two, so as to play a corresponding blocking role for the butterfly wrench 94 in the feeding chute 811, and the When the braided hose 93 of the butterfly wrench 94 moves forward following the rotation of the conveying chain 61, the baffle 822 can be pushed open and turned upward by a certain angle, so that the butterfly wrench 94 can smoothly discharge materials from the bottom discharge port of the feeding pipe 81. In addition, a counterweight rod can be fixed on the baffle 822, and a counterweight weight can be set to increase the overall weight of the baffle 822, so that the baffle 822 can be more stably in the blocking position by its own weight, and play a good blocking role for the butterfly wrench 94 in the feeding chute 811. By setting the butterfly wrench feeding device 8, it can be realized The butterfly wrench 94 is now automatically fitted onto the braided hose 93 without manual fitting, which is beneficial to reducing labor costs and further improving the overall assembly efficiency. In addition, in conjunction with the arrangement of the two conveying chains 61, the butterfly wrench 94 can be restricted between the clamping mechanisms 66 of the two conveying chains 61.

The pulling rod 21 is arranged horizontally and one end of it is fixedly installed on the bottom of the pulling seat 22. The other end of the pulling rod 21 is provided with a pulling head 211. The end of the pulling head 211 is pointed or semicircular, and the outer peripheral surface of the pulling head 211 is wavy. The pulling head 211 can be inserted into one end of the braided hose 93 and the two are tightly fitted.

[0044] Specifically, the linear drive component includes a mounting seat 231, a sliding seat 232, a linear guide slider module 233, a transmission screw 234 and a rotating motor 235. Preferably, the rotating motor 235 is a servo motor. The mounting seat 231 is fixedly mounted on a side surface of the mounting frame 92. The sliding seat 232 is slidably connected to the mounting seat 231 through the linear guide slider module 233. The transmission screw 234 is rotatably mounted on the mounting seat 231. The transmission screw 234 passes through the sliding seat 232 and the two are threadedly matched. The rotating motor 235 is fixedly mounted on the mounting seat 231 and is transmission-connected to one end of the transmission screw 234 through a coupling. The pulling The seat 22 is fixedly installed at the lower end of the sliding seat 232, and the transmission screw 234 is driven to rotate by the rotating motor 235. The sliding seat 232 and the transmission screw 234 are matched by the threaded transmission, and the guiding role of the linear guide slider module 233 can make the sliding seat 232 slide relative to the transmission screw 234, thereby driving the pulling seat 22 to move, and the pulling rod 21 to move, so that the pulling head 211 of the pulling rod 21 is inserted into one end of the braided hose 93 and then the braided hose 93 is pulled to move, or the pulling head 211 of the pulling rod 21 is detached from one end of the braided hose 93.

[0045] In addition, in other embodiments, the linear drive component may also be a linear motor or a pneumatic slide, etc.

[0046] In addition, the clamping cylinder 41 is arranged near the cutting device 5. In this way, when the arc cutter 52 cuts the braided hose 93, the clamping device 4 can play a better clamping and fixing role on the braided hose 93 near the cutting, so that the arc cutter 52 can cut the braided hose 93 more smoothly. In addition, when the pulling head 211 of the pulling rod 21 is to be inserted into one end of the braided hose 93 after cutting, it can also ensure that the pulling head 211 can be inserted into one end of the braided hose 93 more smoothly.

[0047] In addition, the linear guide slider module 233 can adopt the structure in the prior art, so it will not be described in detail here.

[0048] The braided hose assembly device 1 is provided on both sides of the clamping and conveying device 6, and correspondingly, a plurality of clamping mechanisms 74 are also provided on both sides of the clamping and conveying device 6. In this way, the two ends of the braided hose 93 are first clamped and fixed by the clamping mechanisms 74 on both sides of the clamping and conveying device 6, and then, the two ends of the braided hose 93 are assembled at the same time by the braided hose assembly devices 1 on both sides of the clamping and conveying device 6, so as to solve the problem in the prior art that the automatic assembly equipment can only assemble one end of the braided hose 93, and there is no need to manually remove and re-clamp it, which can greatly improve the overall assembly efficiency.

[0049] The production process of the braided hose automatic assembly production line of the present invention is as follows:

[0050] Step 1: unwinding the rolled braided hose 93 by the unwinding device 3;

[0051] Step 2: The unwound braided hose 93 is laterally straightened, pulled and longitudinally straightened in sequence by the transverse straightening device 71, the pulling device 72 and the longitudinal straightening device 73;

[0052] Step 3: The two clamping blocks 42 are driven to approach each other by the clamping cylinder 41 to clamp the end of the braided hose 93. At the same time, the pressing cylinder 751 drives the pressing wheel 752 to move downward and press down the pressing rod 6611 on the first clamping block 661 to increase the opening size of the clamping groove 664 between the first clamping block 661 and the second clamping block 662. Then, the pulling drive mechanism 23 drives the pulling rod 21 to move to the side close to the braided hose 93, and the pulling rod 21 passes through the clamping groove 664 and the butterfly wrench 94 at the bottom of the feed pipe 81, and then the pulling head 211 of the pulling rod 21 is inserted into one end of the braided hose 93 with a tight fit between the two.

[0053] Step 4: The two clamping blocks 42 are driven to move away from each other by the clamping cylinder 41 to loosen the end of the braided hose 93, and then the pulling rod 21 is driven to move to a side away from the braided hose 93 by the pulling drive mechanism 23, so as to pull the braided hose 93 to the clamping mechanism 66 at the feeding end of the clamping conveying device 6;

[0054] Step 5: The two clamping blocks 42 are driven to approach each other by the clamping cylinder 41 to clamp the braided hose 93 again, and then the pressing wheel 752 is driven to move upward by the pressing cylinder 751 and no longer press the pressing rod 6611 on the first clamping block 661. At this time, the first clamping block 661 is flipped and reset under the elastic force of the tension spring 663, and clamps the braided hose 93 with the cooperation of the second clamping block 662. Then, the braided hose 93 is cut into sections by the cutting device 5. At the same time, the pulling rod 21 is driven to move to the side away from the braided hose 93 by the pulling drive mechanism 23 again, so that the pulling head 211 of the pulling rod 21 is separated from one end of the braided hose 93.

[0055] Step 6: The conveying chain 61 is driven to rotate intermittently by the intermittent rotation driving mechanism 65, thereby driving the braided hose 93 in sections and provided with butterfly wrenches 94 to intermittently pass through the multiple assembly stations 11 on the braided hose assembly device 1 in sequence and automatically assemble the two ends of the braided hose 93 in sections simultaneously, and before assembly, the two ends of the braided hose 93 in sections are respectively pressed and fixed by the pressing mechanisms 74 on both sides;

[0056] Step 7: The braided hose 93 with both ends assembled is driven by the clamping conveying device 6 to continue conveying forward and unloading.

[0057] The above are only some specific implementation methods of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
