The second cloth roller at the bottom is limited by the blocking unit 35 to realize single roll unloading.

[0023] More specifically, the blocking unit 35 is fixed by bolts to the lower wall of the end of the first material seat 32 away from the feeding port. Its main function is to limit the stacked cloth rolls to ensure that only a single cloth roll is released each time. Specifically, after the cloth roll is put in from the feeding port, it slides toward the bottom of the first material seat 32 and the second material seat 34 under the action of gravity. The bottom cloth roll is blocked by the blocking unit 35, and the upper cloth rolls are stacked above it in sequence; when the cloth roll needs to be released, the blocking unit 35 releases the blockage, allowing the bottom cloth roll to slide toward the discharge structure 4, and then quickly resets to block the next cloth roll, realizing orderly unloading of single rolls.

The rack 356 is driven to move by the electric push rod 355, and the gear 353 is driven by the rack 356 to realize the flipping of the blocking arm 354, and the blocking arm 354 is flipped upward to fit the cloth roll limit.

[0025] More specifically, when it is necessary to block the cloth roll, the electric push rod 355 contracts, driving the rack 356 to move toward the direction close to the electric push rod 355, and the rack 356 engages the driving gear 353 to rotate clockwise, causing the blocking arm 354 to flip upward to the middle position between the first material seat 32 and the second material seat 34, and its free end fits against the outer wall of the cloth roll to limit the cloth roll; when it is necessary to release the cloth roll, the electric push rod 355 extends, the rack 356 moves away from the electric push rod 355, and the driving gear 353 rotates counterclockwise, and the blocking arm 354 flips downward to the bottom of the first material seat 32 and the second material seat 34, thereby releasing the blockage of the cloth roll, and the cloth roll slides toward the discharge structure 4 under the action of gravity.

[0026] like Figure 6As shown, as a preferred embodiment, further, the discharge structure 4 includes an adjustment seat 41, a pair of adjustment frames 42, a pair of adjustment screws 43 and a discharge assembly 44; the adjustment seat 41 is T-shaped, one end of the adjustment seat 41 is fixedly set on the material frame 31, and the other end of the adjustment seat 41 is located below the other end of the first material seat 32. A T-shaped adjustment slot 5 is provided in the middle of the other end of the adjustment seat 41, and one end of the pair of adjustment frames 42 is movably inserted into the adjustment slot 5 of the adjustment seat 41, and the other ends of the pair of adjustment frames 42 are respectively located on the front and rear sides of the other end of the first material seat 32 and the second material seat 34. The adjusting screws 43 are movably screwed into the adjusting frames 42, and the adjusting screws 43 are pressed against the adjusting seats 41, and the discharge assembly 44 is movably arranged on the adjusting frames 42; the adjusting seats 41 carry the adjusting frames 42, so that the spacing of the adjusting frames 42 can be changed to match the spacing of the first material seat 32 and the second material seat 34. The cloth rolls are received by the discharge assembly 44 for buffering and unloading. The first discharge rack 441 and the second discharge rack 442 correspond to the lower wall edge of the other end of the first material seat 32 and the second material seat 34, and the first discharge rack 441 and the second discharge rack 442 rotate counterclockwise.

[0027] More specifically, according to the length specifications of the fabric roll, first loosen the adjusting screw 43, push the two adjusting frames 42 to slide along the adjusting slot 5 of the adjusting seat 41, so that the spacing of the adjusting frames 42 matches the spacing of the first material seat 32 and the second material seat 34, and then tighten the adjusting screw 43 to fix the adjusting frames 42; when the stacking structure 3 releases the fabric roll, the unloading assembly 44 receives the fabric roll and smoothly transports it to the conveyor belt body 2 through a buffering action, completing the unloading process.

[0028] like Figure 6 and Figure 7As shown, as a preferred embodiment, further, the unloading assembly 44 includes a first unloading rack 441, a second unloading rack 442, a motor 443, a pair of pulleys 444 and a belt 445; one end of the first unloading rack 441 movably passes through the other end of one of the adjustment racks 42, and the first unloading rack 441 is located on the left side of the other end of the first material seat 32, the other end of the first unloading rack 441 is a semicircular structure, and the other end of the first unloading rack 441 is provided with an arc-shaped telescopic slot 6, the first unloading rack 441 is located above the rear end of the conveyor belt body 2, the second unloading rack 442 is the same as the first unloading rack 441, one end of the second unloading rack 442 is movably set on another adjustment rack 42, and the second unloading rack 44 2 The other end is movably inserted into the other end of the first unloading rack 441, the motor 443 is fixedly installed on one of the adjustment racks 42, and a pair of pulleys 444 are respectively fixedly installed on the driving end of the motor 443 and one end of the first unloading rack 441. The belt 445 is movably sleeved on the pulley 444; when the motor 443 is started, the pulley 444 and the belt 445 are used to drive the first unloading rack 441 to rotate, and the second unloading rack 442 is driven to rotate. The first unloading rack 441 and the second unloading rack 442 receive the cloth rolls and realize buffering unloading as they rotate. The motor 443 drives the first unloading rack 441 and the second unloading rack 442 to rotate through the belt 445 and the pulley 444. More specifically, after the motor 443 is started, its driving end drives the corresponding pulley 444 to rotate, and through the belt 445, drives the pulley 444 at one end of the first unloading rack 441 to rotate synchronously, thereby causing the first unloading rack 441 to rotate around its own axis; since the second unloading rack 442 is plug-in matched with the first unloading rack 441 and the two have the same structure, the rotation of the first unloading rack 441 will drive the second unloading rack 442 to rotate synchronously; when the cloth roll slides off the stacking structure 3, the semicircular structure of the first unloading rack 441 and the second unloading rack 442 catches the cloth roll, and as the two rotate counterclockwise, the cloth roll gradually descends under the support of the semicircular structure, and is finally placed stably on the conveyor belt main body 2, realizing buffered unloading and preventing the cloth roll from being damaged by direct falling.

[0029] Working principle: Fabric roll buffering and limiting of stacking structure 3: The stacking structure 3 tilts the first material seat 32 and the second material seat 34 through the material rack 31, and uses gravity to make the cloth rolls automatically slide along the inclined surface and stack in order; the concave shapes of the first material seat 32 and the second material seat 34 enable both ends of the cloth roll to bear and roll; wherein, the first electric slide rail 33 can adjust the distance between the second material seat 34 and the first material seat 32 to adapt to cloth rolls of different lengths; the staff puts the cloth roll between the two material seats through the feeding port of the first material seat 32, and the cloth roll slides to the bottom under the action of gravity. The cloth roll at the bottom is temporarily limited by the material blocking unit 35 to ensure the stable stacking state; Single roll release control of the blocking unit 35: The blocking unit 35 adjusts the position of the shaft frame 352 through the second electric slide rail 351, so that the blocking arm 354 is aligned with the blocking point of the fabric roll, which fits fabric rolls of different diameters; when the fabric roll needs to be released, the electric push rod 355 extends, driving the rack 356 to move, and the rack 356 engages the drive gear 353 to rotate, causing the blocking arm 354 to flip downward, releasing the blocking of the bottom fabric roll; after the fabric roll slides out, the electric push rod 355 contracts, and the blocking arm 354 flips upward and resets to block the next fabric roll, realizing the orderly release of a single roll; Buffer receiving and unloading of unloading structure 4: The adjustment frame 42 of the material discharging structure 4 can adjust the spacing through the T-shaped adjustment slot 5 of the adjustment seat 41 to adapt to the length of the fabric roll. After adjustment, it is fixed by the adjustment screw 43 to achieve the spacing between the first material seat 32 and the second material seat 34. In addition, the spacing adjustment of the adjustment frame 42 will drive the second material discharging frame 442 to extend from the telescopic slot 6 of the first material discharging frame 441 to achieve the docking length of the first material discharging frame 441 and the second material discharging frame 442. When the cloth roll slides out from the stacking structure 3, that is, the cloth slides out from the bottom of the first material seat 32, the first unloading rack 441 and the second unloading rack 442 of the unloading assembly 44 are plugged into and matched with each other through the telescopic slot 6 to adapt to the length change and receive the cloth roll; the motor 443 is driven by the pulley 444 and the belt 445, and the first unloading rack 441 rotates counterclockwise, driving the second unloading rack 442 to rotate synchronously, and the cloth roll gradually descends as the second unloading rack 442 rotates and falls onto the conveyor belt body 2, completing the buffer loading corresponding to the packaging rhythm.

[0030] Transfer coordination of conveyor belt body 2: The conveyor belt body 2 on the base 1 receives the fabric roll dropped from the discharge structure 4 and transports it to the subsequent packaging station. At the same time, it triggers the blocking unit 35 to release the next fabric roll and enter the next cycle, realizing continuous automatic loading in line with the packaging rhythm.

[0031] In summary, the equipment achieves flexible adaptation, orderly stacking, single-roll release and smooth transportation of glass fiber cloth rolls through the linkage coordination and automated control of the mechanical structure, thereby improving the efficiency and stability of packaging and loading.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention and are not limiting. Other modifications or functional replacements made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
