DETAILED DESCRIPTION

[0027] like Figures 1 to 6 The fabric spreading device shown in the figure includes a discharging mechanism 2 and a spreading mechanism 3. The discharging mechanism 2 includes a main roller 21, an upper pressure roller 22, and a lower pressure roller 23, with the upper pressure roller 22 and the lower pressure roller 23 located on the upper and lower sides of the main roller 21, respectively. The fabric is fed into and out of the gap between the main roller 21 and the lower pressure roller 23. The spreading mechanism 3 includes two conveyor belts 32 driven by different drive motors 31, and the two conveyor belts 32 drive the fabric toward the ends of the main roller 21 in the longitudinal direction. By arranging the two sets of conveyor belts 32 rotating in opposite directions in front of the gap between the main roller 21 and the lower pressure roller 23, the fabric fed into the main roller 21 is flattened from the center to the ends by the conveyor belts 32, so that the fabric can be smoothly conveyed into the main roller 21, effectively preventing wrinkles and curling caused by rebound of the fabric before entering the main roller 21.

[0028] In a possible embodiment, the outer surface of the conveyor belt 32 is provided with a number of evenly arranged ridges, so that the surface of the conveyor belt 32 is uneven, thereby increasing the friction effect between the cloth and the conveyor belt 32, and making it easier to drive the cloth to be flattened toward both ends of the length direction of the main roller 21.

[0029] In this embodiment, the main roller 21 is installed in the main roller installation groove 1; the main roller installation groove 1 includes a main roller windshield 11 and a main roller side plate 12, and the two ends of the main roller 21 can be rotatably installed on the main roller side plate 12, and the spreading mechanism 3 is installed in the main roller installation groove 1.

[0030] Specifically, the two drive motors 31 are respectively installed at the two ends of the main pipe mounting groove 1, a driving wheel is provided on the power output shaft of the drive motor 31, two driven wheels are symmetrically provided in the middle of the main roller mounting groove 1, and the two ends of the two conveyor belts 32 are respectively mounted on a driving wheel and a driven wheel.

[0031] Optionally, both the driving wheel and the driven wheel are synchronous wheels, and the conveyor belt 32 is a synchronous belt.

[0032] like Figure 4 and Figure 6As shown, the upper and lower pressure rollers 22 and 23 are connected via a pressure roller connection module 4. The pressure roller connection module 4 includes a pressure roller side plate 41, a connecting shaft 45, and a locking block 43. The upper and lower pressure rollers 22 and 23 are rotatably mounted on the pressure roller side plate 41 at both ends, while one end of the pressure roller side plate 41 is rotatably mounted on the main roller side plate 12. The locking block 43 is used to lock the other end of the pressure roller side plate 41 to the main roller side plate 12. The pressure roller side plates 41 are connected via a connecting shaft 45. The connecting shaft 45 supports the pressure roller side plate 41, preventing the portion of the pressure roller side plate 41 that is farther from the upper and lower pressure rollers 22 and 23 from shifting inward, thereby affecting the operation of the main roller 21.

[0033] Specifically, the pressure roller side plate 41 includes a first connecting plate 411 and a second connecting plate 412. The upper pressure roller 22 is mounted on the first connecting plate 411, and the lower pressure roller 23 is mounted on the second connecting plate 412. One end of the first connecting plate 411 is hingedly connected to the main roller side plate 12, and the other end is mounted with the second connecting plate 412. One end of the locking block 43 is hingedly connected to the first connecting plate 411 via a hinge post 431. A first post 413 is provided on the first connecting plate 411 near the locking block 43, and a second post 432 is provided on the end of the locking block 43 away from the hinge post 431. The first post 413 and the second post 432 are connected by an elastic member 433. A latch is provided on the locking block 43, located on the side of the second post 432 away from the hinge post 431. A latch post 13 is provided on the main roller side plate 12, and the latch is latched onto the latch post 13. A first handle 42 is provided on the first connecting plate 411 , and a second handle 44 is provided on the locking block 43 . The second handle 44 and the hinge column 431 are located at the same end of the locking block 43 .

[0034] By forming a modular structure, the upper pressure roller 22, the lower pressure roller 23, the first connecting plate 411, the second connecting plate 412 and other structures can be assembled before installation, and then the first connecting plates 411 at both ends can be rotatably installed on the main roller side plates 12, and then the first connecting plates 411 are rotated to make the upper pressure roller 22 and the lower pressure roller 23 rotate to the corresponding positions of the main roller 21 respectively, and then the locking block 43 can be clamped on the clamping column 13. The on-site installation and disassembly of the entire structure are more convenient, and it is also easier to repair when encountering a main roller failure.

[0035] Specifically, when the fabric needs to be replaced or disassembled, the operator directly pinches the second handle 44 and the first handle 42 at the same time, and moves the second handle 44 closer to the first handle 42, so that the locking block 43 rotates with the hinge column 431 as the axis, so that the latch at the other end of the locking block 43 is disengaged from the column 13, and then the first handle 42 can be continued to be driven to rotate the first connecting plate 411 with the connection point with the main roller side plate 12, so that the entire pressure roller connection module 41 drives the upper pressure roller 22 and the lower pressure roller 23 to rotate.

[0036] In this embodiment, the first connecting plate 411 and the second connecting plate 412 form a semicircular structure, and the hinge axis between the first connecting plate 411 and the main roller side plate 12 is arranged near the upper pressure roller 22, so that the entire pressure roller connecting module 4 can rotate the lower pressure roller 23 out from under the main roller 21 when it rotates.

[0037] In this embodiment, the elastic member 433 is a tension elastic member, such as a tension spring or rubber band. The first post 413 is disposed below the hinge post 431. When there is no external force, the elastic member 433 pulls the second post 432 toward the first post 431 until the middle portion of the lower end of the locking block 43 abuts the first post 413. When the locking block 43's tab is engaged with the post 13, the locking block 43 and the first post 413 are not in contact. Under the elastic force of the elastic member 433, the locking block 43's tab remains firmly engaged with the post 13 below the locking block 43. The locking block 43's tab is not released from the post 13 until the force exerted on the second handle 44, which drives the locking block 43 to rotate, exceeds the force exerted by the elastic member 433 on the second post 432. At this point, the locking block 43's tab is released from the post 13 under the action of the external force. Therefore, when the present invention is used normally, the elastic member 433 can enable the locking block 43 to clamp the clamping column 13, thereby fixing the entire pressure roller connection module 4, so that the main roller 21, the upper pressure roller 22 and the lower pressure roller 23 can operate normally and the cloth can be transported normally.
