[0024] According to a specific embodiment of the application, as shown in Figures 1-10 The application provides a high-flexibility prefabricated T-beam prestressed tendon positioning net processing production line, which comprises: A straightening and cutting machine 1 is used to cut the steel bars into short bars or long bars of a set length.

[0025] The reinforcing bar conveying mechanism 11 is located downstream of the straightening and cutting machine 1 and is used to convey short reinforcing bars or long reinforcing bars. In this embodiment, the reinforcing bar conveying mechanism 11 is a conveying chain, which is arranged at a position downstream of the outlet of the straightening and cutting machine 1, and the extending direction of the reinforcing bar conveying mechanism 11 is parallel to the discharging direction of the straightening and cutting machine 1.

[0026] A short reinforcing bar buffer mechanism 10 and a long reinforcing bar buffer mechanism 2 are arranged at one side of the reinforcing bar conveying mechanism 11. The short reinforcing bar buffer mechanism 10 includes a plurality of short reinforcing bar buffer chains and is used to buffer short reinforcing bars. The long reinforcing bar buffer mechanism 2 includes a plurality of long reinforcing bar buffer chains 21 and is used to buffer long reinforcing bars.

[0027] A bracket mechanism 3 and a welding mechanism are arranged side by side at the inner side of the short reinforcing bar buffer chains and the long reinforcing bar buffer chains 21. The bracket mechanism 3 includes a plurality of bracket frames 31 and is used to hold positioning nets composed of long reinforcing bars and short reinforcing bars. The welding mechanism is used to weld the intersection points of the long reinforcing bars and the short reinforcing bars. The welding mechanism includes at least one welding machine 8. In this embodiment, the welding mechanism includes a ground rail, and at least one resistance welding machine is arranged to slide on the ground rail.

[0028] A short reinforcing bar feeding mechanism 9 is arranged at the outer side of the short reinforcing bar buffer chains and is used to grab short reinforcing bars and place them on the bracket frames 31.

[0029] A long reinforcing bar feeding mechanism 4 and a transfer mechanism 5 are arranged at the outer side of the long reinforcing bar buffer chains 21. The long reinforcing bar feeding mechanism 4 is used to grab long reinforcing bars and place them on the bracket frames 31.

[0030] A splicing and welding table 7 is arranged downstream of the bracket mechanism 3 and is located at one side of the welding mechanism. The transfer mechanism 5 is used to grab a plurality of positioning nets of different sizes to the splicing and welding table 7, and the welding mechanism is used to weld the plurality of positioning nets into T-beam positioning nets.

[0031] A buffer rack 6 is arranged at the other side of the splicing and welding table 7 away from the welding mechanism, and the transfer mechanism 5 is used to grab the T-beam positioning nets to the buffer rack 6 for temporary storage.

[0032] In this processing line, the reinforcing bars are cut into short reinforcing bars or long reinforcing bars of desired lengths by the straightening and cutting machine 1. The cut short reinforcing bars or long reinforcing bars enter the reinforcing bar conveying mechanism 11, which conveys the short reinforcing bars or long reinforcing bars downstream. When the short reinforcing bars are conveyed to the position of the short reinforcing bar buffer mechanism 10, the short reinforcing bars enter the short reinforcing bar buffer mechanism 10 and are temporarily stored on the short reinforcing bar buffer chains. When the long reinforcing bars are conveyed to the position of the long reinforcing bar buffer mechanism 2, the long reinforcing bars enter the long reinforcing bar buffer mechanism 2 and are temporarily stored on the long reinforcing bar buffer chains 21.

[0033] The short rib feeding mechanism 9, located outside the short rib buffer chain, grabs the short ribs and places them on the bracket frame 31 inside the short rib buffer chain. The long rib feeding mechanism 4, located outside the long rib buffer chain 21, grabs the long ribs and places them on the bracket frame 31 inside the long rib buffer chain 21. Then, the welding mechanism arranged in parallel on one side of the bracket mechanism 3 welds the intersection of the short ribs and the long ribs to form positioning nets of different sizes.

[0034] The transfer mechanism 5, located outside the long rib buffer chain 21, picks up multiple positioning nets and places them onto the welding station 7. The welding mechanism then welds the multiple positioning nets into a T-beam positioning net. The transfer mechanism 5 then picks up the T-beam positioning net from the welding station 7 and places it onto the buffer rack 6 for temporary storage. Repeating the above process can achieve continuous production of T-beam positioning nets.

[0035] In summary, the buffer chain in this processing line is located near the bracket frame 31, the feeding mechanism is located near the buffer chain, and the welding mechanism is located near the bracket frame 31 and the welding station 7. This makes the distribution of each mechanism in the processing line reasonable and the connection between each process smooth.

In other embodiments, the web positioning net short web on the short web feeding mechanism 11 can also be placed on the second sliding channel 102 by manual operation, which can be selected according to the actual situation.

[0041] Wherein, a short web falling platform 109 is arranged between the second push plate machine 104 and the second short web buffer chain 108, the short web falling platform 109 is provided with a pushing cylinder 105 away from the second short web buffer chain 108, the second short web buffer chain 108 is provided with a short web centering mechanism 106 close to the short web falling platform 109, the short web centering mechanism 106 comprises two opposite push plates, at least one of the two push plates is controlled to move by a cylinder; specifically, when the web positioning net short web is transported to the short web falling platform 109 by the second push plate machine 104, the pushing cylinder 105 pushes the short web onto the short web falling platform 109, and then the short web falls from the falling groove of the short web falling platform 109 onto the second short web buffer chain 108 at the bottom of the short web falling platform 109, when the short web reaches the position of the short web centering mechanism 106, the cylinder drives the push plate to move, so that the position of the short web is kept consistent.

The long rib centering mechanism 23 is used to adjust the position of the long ribs.

[0044] In this embodiment, the long rib pushing mechanism 22 includes two cylinders and a push rod. The two cylinders are respectively connected to the two ends of the push rod. The extension direction of the push rod is parallel to the extension direction of the long rib, and the length of the push rod is greater than the length of the long rib, so that the push rod can push the long rib more evenly.

The motor drives the screw to rotate. The screw is parallel to the rib feeding mechanism 11. The baffle is provided with a threaded hole and at least one guide hole.

At this time, the cylinder in the long bar pushing mechanism 22 works, and the push rod drives the long bar to move horizontally, so that the long bar falls from the feeding mechanism 11 onto the long bar dropping platform 12. Then the long bar continues to slide onto the multiple sets of long bar buffer chains 21. The multiple sets of long bar buffer chains 21 move forward synchronously, driving the long bar forward, thereby providing a buffer position for the next long bar.

[0048] All the long rib buffer chains 21 together support the long ribs of the web positioning net, and the two long rib buffer chains 21 located in the middle are used to support the long ribs of the bottom plate positioning net.
