[0028] The materials for printing and dyeing are basically wound around the winding drum (rack), and the winding drum (rack) is a carrier with a circular mounting aperture. When the printing and dyeing equipment is in use, it is necessary to fix the materials first and then unwind them.

[0029] In the related art, generally, the arc-shaped pressing plate is connected to the top of the vertical plate by means of bolt connection. After the unwinding roller is placed on the vertical plate, the arc-shaped plate restricts the top to prevent the unwinding roller from disengaging from the inside of the vertical plate, so that the unwinding roller is restricted. However, for the fixed connection method of the arc-shaped plate by bolts, either a tool is used to turn the bolts or manually turned, and it takes a certain amount of time to complete the installation or disassembly during the turning, making the installation and disassembly cumbersome and inefficient.

[0030] To solve the problems in the related art to a certain extent, an embodiment of the present application provides a loading and unwinding device. When it is necessary to load and unwind the paper roll 13, first fix the paper roll 13 on the unwinding roller 12, and then place the unwinding roller 12 on the vertical plate 11. The top of the unwinding roller 12 is not fixed, so it needs to be fixed. At this time, the bottom end of the arc-shaped plate 21 can be inserted from the inner side wall of the fixing block 23. When inserting, the inclined block 28 will contact the clamping block 25 and squeeze the clamping block 25 to retract into the cavity of the fixing block 23. Continue to move downward until it contacts the card slot 22, and the spring 24 rebounds to push the clamping block 25 into the card slot 22 to complete the fixation of the arc-shaped plate 21, which also restricts the unwinding roller 12 from falling off the top of the vertical plate 11. When disassembling the arc-shaped plate 21, only need to pull the pull rod 26 to separate the clamping block 25 from the card slot 22, and then pull out the arc-shaped plate 21 from the inner side of the fixing block 23.

[0031] The present application will be described below with reference to the accompanying drawings and specific embodiments:

[0032] Combined Figures 1-4 An embodiment of the present application provides a loading and unwinding device, including: a vertical plate 11, a top of the vertical plate 11 is provided with an unwinding roller 12; a paper roll 13 is arranged on an outer side wall of the unwinding roller 12; a fixing component 2 is provided on the top of the vertical plate 11, and the fixing component 2 includes: an arc-shaped plate 21 is arranged on the top of the vertical plate 11; a card slot 22 is opened on an outer side wall of the arc-shaped plate 21; a fixing block 23 is arranged on one side of the vertical plate 11 and has a cavity inside; a spring 24 is arranged inside the cavity of the fixing block 23; a clamping block 25 is arranged at one end of the spring 24; one end of a pull rod 26 penetrates through an outer side wall of the fixing block 23 and is connected to the clamping block 25.

[0033] Specifically, the fixing block 23 is fixedly welded to the vertical plate 11, one end of the pull rod 26 is fixedly welded to the clamping block 25, and both ends of the spring 24 are fixedly connected to the clamping block 25 and the inner side wall of the fixing block 23 by means of snap rings. The fixing method of the snap rings belongs to well-known technology and will not be elaborated here too much.

[0034] When in use, when it is necessary to fix the unwinding roller 12, first pull the pull rod 26 to drive the clamping block 25 to retract into the fixing block 23 and compress the spring 24, and then insert one end of the bottom of the arc-shaped plate 21 into the inner side of the fixing block 23. At this time, release the pull rod 26, and the spring 24 rebounds to push the clamping block 25 into the card slot 22 to fix the arc-shaped plate 21, and thus the restriction of the unwinding roller 12 is completed.

[0035] In some embodiments, the spring 24 is arranged outside the pull rod 26.

[0036] When in use, such a setting can limit the spring 24 from bending when the spring 24 is compressed, thereby reducing the damage to the spring 24.

[0037] In some embodiments, the top of the clamping block 25 is inclined.

[0038] When in use, the inclined design of the clamping block 25 allows the bottom end of the arc-shaped plate 21 to be directly inserted into the inside of the fixed block 23 without having to pull the pull rod 26 in advance during installation, and can squeeze the clamping block 25 to retract into the inside of the fixed block 23.

[0039] In some embodiments, the fixing assembly 2 further includes: a pull torsion 27 disposed at the other end of the pull rod 26.

[0040] When in use, the setting of the pull torsion 27 makes it convenient to grasp when pulling the pull rod 26, thereby avoiding slipping.

[0041] In some embodiments, the fixing assembly 2 further includes: an inclined block 28 disposed at the bottom of the arc-shaped plate 21.

[0042] When in use, the setting of the inclined block 28 makes it easier for the bottom of the arc-shaped plate 21 to be inserted into the inside of the fixed block 23, and can be fitted with the inclined surface of the clamping block 25 to better squeeze the clamping block 25.

[0043] In some embodiments, the fixing assembly 2 further includes: a convex plate 29 disposed on one side of the vertical plate 11; an L-shaped rod 291 disposed on one side of the arc-shaped plate 21 and penetrating through the convex plate 29 at the bottom.

[0044] When in use, after the fixing of the arc-shaped plate 21 is released, the arc-shaped plate 21 can be rotated. At this time, the L-shaped rod 291 rotates inside the convex plate 29, so that the arc-shaped plate 21 rotates to the other side, avoiding affecting the placement of the unwinding roller 12 on the vertical plate 11. The setting of the convex plate 29 and the L-shaped rod 291 can be used to store the arc-shaped plate 21.

[0045] In some embodiments, the fixing assembly 2 further includes: a stop block 292 disposed at the bottom of the L-shaped rod 291.

[0046] When in use, the setting of the stop block 292 can prevent the L-shaped rod 291 from detaching from the convex plate 29, thereby preventing the loss of the arc-shaped plate 21.
