[0002] During the production and processing of the web, it needs to be rolled up or automatically transported through a roll-feed mechanism. However, most of the current roll-feed mechanisms use a structure with one active roller and two driven rollers, such as Figure 1 As shown, the driven rollers are distributed above and below the active roller, and the screen passes through driven roller one, active roller, and driven roller two in sequence. During this process, since the surface of the rollers is relatively smooth and the transmission force of the driven rollers is taken from the tension in the screen weaving transmission process, the surface of the driven rollers is prone to slippage. Especially in the process of screen weaving, it is also necessary to spray lubricating oil / liquid on the screen surface to reduce the friction between the screen and the roller surface, and the slippage problem becomes more and more serious, thereby affecting the normal operation of the weaving process.

[0032] like Figure 2-7 As shown, a mesh surface rolling anti-slip and anti-falling system for a mesh weaving machine includes an active roller 1, a driven roller 17 and a driven roller 2 2 located between the frames 4 on both sides of the rolling machine. The driven roller 17 and the driven roller 2 2 are distributed on the upper and lower sides of the active roller 1. The specific distribution is as follows Figure 1 The driving roller 1 transmission shaft is connected to the servo motor 15, and the servo motor 15 drives the driving roller 1 to rotate to perform the winding / unwinding operation. The driven roller 17 is connected to the driven roller 1 transmission shaft 16 at the center position key, and the driven roller 1 transmission shaft 16 is connected to the driving roller 1 transmission shaft through the synchronous transmission mechanism 14.

[0033] The transmission force of the driven roller 17 is changed from the original passive rotation driven by the tension of the wire mesh surface to the torque obtained by driving the synchronous transmission mechanism 14 through the shaft end of the active roller 1, so as to realize active rotation and avoid the slippage of the woven mesh surface caused by the uncontrolled free rotation of the driven roller 17.

[0034] The roller shaft 3 of the driven roller 2 is connected to the check bearing 5 after passing through the frame 4. The other end of the check bearing 5 is fixedly connected to the disc brake pad 7. The disc brake pad 7 is frictionally connected to the hydraulic brake caliper system 9 / electronic handbrake pump system 13. The upper end of the check bearing 5 is frictionally connected to the mechanical auxiliary brake system 8. The mechanical auxiliary brake system 2 12 is installed at the upper end of the disc brake pad 7.

[0035] The hydraulic brake caliper system 9 includes brake caliper plates 901 located on both sides of the disc brake pad 7, wherein the brake caliper plate 901 on one side is pushed to move by a piston 902, and the brake caliper plate 901 on the other side is fixed. The piston 902 is slidably installed inside the brake caliper, and the end of the piston 902 away from the brake caliper plate 901 is pushed by hydraulic oil. The brake caliper plate 901 is connected to the master cylinder 904 through a hydraulic oil pipe 903, and a booster piston 906 is slidably installed in the master cylinder 904, and the booster piston 906 is connected to the telescopic mechanism.

[0036] The telescopic mechanism includes a booster rod 907 and a cylinder for driving the booster rod 907 to move. Operation process of the hydraulic brake caliper system 9 embodiment 1: the booster rod 907 pushes the booster piston 906 to move inward, and the hydraulic oil in the master cylinder 904 enters the brake caliper through the hydraulic oil pipe 903, and pushes the piston 902 to push the movable brake caliper pad 901 and the fixed brake caliper pad 901 to clamp the disc brake pad 7 together, thereby playing a braking role.

[0037] The telescopic mechanism adopts an electric push rod 11, and the telescopic end of the electric push rod 11 is fixedly connected to the booster piston 906. Operation process of the hydraulic brake caliper system 9 embodiment 2: the telescopic end of the electric push rod 11 pushes the booster piston 906 to move inward, and the hydraulic oil in the master cylinder 904 enters the brake caliper through the hydraulic oil pipe 903, and pushes the piston 902 to push the brake caliper pad 901 to clamp the disc brake pad 7, thereby playing a braking role.

[0038] The upper oil inlet of the master cylinder 904 is connected to the oil storage tank 905 through an oil pipe to supply oil to the master cylinder 904 .

[0039] An oil storage barrel 10 is installed on the upper end surface of the main oil cylinder 904, and an oil path for the flow of hydraulic oil is installed between the oil storage barrel 10 and the main oil cylinder 904. The oil storage barrel 10 is fixedly connected to the main oil cylinder 904, eliminating the intermediate oil pipe, reducing the occurrence of oil pipe leakage and other problems, and is easy to install, saves space, and has a neat and beautiful appearance.

[0040] The other end of the check bearing 5 is fixedly connected to the connecting sleeve 6, and the upper ends of the check bearing 5 and the connecting sleeve (6) are frictionally connected to a mechanical auxiliary brake system 8; the mechanical auxiliary brake system 8 includes an arc-shaped brake pad 801 located above the check bearing 5 and the connecting sleeve 6, and the upper end of the arc-shaped brake pad 801 is fixedly connected to a U-shaped connecting groove 802, and the notch of the U-shaped connecting groove 802 is fixedly connected to a connecting rod 803, and the upper end of the connecting rod 803 is integrally formed with a connecting ring 804, and a rotating shaft 805 is rotatably installed in the connecting ring 804, and a torsion spring 806 is sleeved on the rotating shaft 805; one end of the torsion spring 806 is clamped on the rotating shaft 805, and the other end is fixedly connected to the connecting ring 804; the other end of the rotating shaft 805 is connected to a cross bar 810 through a ring 807, and the other end of the cross bar 810 is fixedly connected to the frame 4.

[0041] A vertex 808 is installed on the rotating shaft 805 outside the collar 807, and an auxiliary support rod 809 is installed at the lower end of the vertex 808. The auxiliary support rod 809 is connected to the hydraulic brake caliper system 9. Specifically, the hydraulic brake caliper system 9 plays a stabilizing role through the auxiliary support rod 809.

[0042] The rotating shaft 805 rotates, and the torsion spring 806 rotates accordingly. The torque generated during the rotation is converted into pressure to squeeze the connecting rod 803 downward, so that the arc-shaped brake pad 801 is pressed against the outer surface of the check bearing 5 and the connecting sleeve 6, limiting the roller shaft 3 from rotating at an excessive speed, playing a certain restraining role.

[0043] The mechanical auxiliary brake system 2 12 includes cards 1201 with brake pads symmetrically distributed on the left and right sides of the upper part of the disc brake pad 7, the upper end of the card 1201 with brake pads is installed with a sliding sleeve 1202, the sliding sleeve 1202 is slidably connected to a slide bar 1203, and one end of the sliding sleeve 1202 is fixedly installed on the frame 4; a tightening bolt 1204 is installed on the sliding sleeve 1202, and the end of the tightening bolt 1204 is against the slide bar 1203. The distance between the card 1201 and the disc brake pad 7 is adjusted by moving the sliding sleeve 1202 on the slide bar 1203. When the card 1201 is against the disc brake pad 7, it plays a role in restricting the rotation speed of the check bearing 5, that is, restricting the roller shaft 3 from rotating too fast.

[0044] The electronic handbrake pump system 13 includes a motor 1301, and the motor 1301 is connected to a reducer 1302 through a transmission assembly. The output end of the reducer 1302 is connected to a screw mechanism 1303, and the other end of the screw mechanism 1303 is connected to a piston assembly 1304. The other end of the piston assembly 1304 is slidably installed in a brake cylinder 1305. A caliper housing is installed on the outside of the brake cylinder 1305, and a caliper 1306 in contact with the disc brake pad 7 is installed on the outer wall of the caliper housing; caliper guides 1307 are installed at the upper and lower ends of the caliper housing.

[0045] Specifically, since the hydraulic brake caliper system 9 needs to be frequently depressurized to ensure its normal operation, an electronic handbrake pump system 13 can be used to keep it in a maintenance-free state for a long time. The motor 1301 rotates, and the transmission assembly (either a gear rack transmission or a synchronous wheel and synchronous belt transmission) transmits the rotational action to the reducer 1302 (a planetary reducer can be used). After the reducer 1302 decelerates, the screw mechanism 1303 starts, driving the piston assembly 1304 to move on the brake cylinder 1305, thereby realizing the clamping of the caliper 1306 on the disc brake pad 7 to achieve the purpose of braking.

[0046] The action process of the present invention is as follows:

[0047] Preventing the roller shaft 3 from reversing and the mesh surface from slipping Example 1: The telescopic mechanism is started, pushing the booster piston 906 to move inward, and the hydraulic oil in the master cylinder 904 enters the brake caliper through the hydraulic oil pipe 903, and pushes the piston 902 to push the brake caliper plate 901 to clamp the disc brake pad 7, and the connecting sleeve 6 fixedly connected thereto brakes, and under the limiting action of the connecting sleeve 6, the check bearing 5 prohibits the roller shaft 3 from rotating in the reverse direction;

[0048] Embodiment 2 of preventing the roller shaft 3 from reversing and the mesh surface from slipping: start the motor 1301, the transmission assembly transmits the rotational motion to the reducer 1302, after the reducer 1302 decelerates, the screw mechanism 1303 starts, driving the piston assembly 1304 to move on the brake cylinder 1305, so that the caliper 1306 clamps the disc brake pad 7, and the check bearing 5 prohibits the roller shaft 3 from reversing;

[0049] Example 1 of the roller shaft 3 that needs to be reversed: At this time, the telescopic mechanism is closed, and the hydraulic oil releases the restriction on the brake caliper plate 901, the brake caliper plate 901 returns to its original position, the disc brake pad 7 is free, and the connecting sleeve 6 also regains its freedom, and no longer restricts the reverse rotation of the check bearing 5; then, the rotating shaft 805 is rotated, and the torsion spring 806 rotates accordingly. The torque generated during the rotation is converted into pressure to squeeze the connecting rod 803 downward, thereby making the arc-shaped brake pad 801 press against the outer surface of the check bearing 5 and the connecting sleeve 6, limiting the roller shaft 3 from rotating at an excessive speed, thereby achieving the purpose of restraining the rotation.

[0050] The roller shaft 3 needs to be reversed. Example 2: Start the motor 1301 to make it rotate in the opposite direction. The transmission assembly transmits the reverse rotation action to the reducer 1302. After being decelerated by the reducer 1302, the screw mechanism 1303 is started, driving the piston assembly 1304 to move back in the brake cylinder 1305, so that the caliper 1306 releases the brake on the disc brake pad 7, and the check bearing 5 no longer restricts the reverse rotation of the roller shaft 3; then, the sliding sleeve 1202 is pushed to move on the sliding rod 1203 to adjust the distance between the card 1201 and the disc brake pad 7. When the card 1201 is against the disc brake pad 7, the check bearing 5 is limited from rotating too fast, that is, the roller shaft 3 is restrained from rotating too fast.

[0051] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
