Description

Technical Field

[0001] The utility model relates to the technical field of curtain fabric production, in particular to a curtain fabric winding device. Background Art

[0002] In the curtain fabric production process, weaving and printing and dyeing equipment are usually used to make the required curtain fabric. After the curtain fabric is woven, it is generally necessary to roll the curtain fabric into a roll to facilitate the storage, transportation and subsequent further processing of the curtain fabric. Therefore, a winding device is required.

[0003] A Chinese patent application numbered CN220975968U discloses a textile fabric winding device. The device uses a rotating motor to drive a rotating shaft to rotate clockwise, which in turn drives a guide plate on top of the rotating shaft to rotate clockwise. Simultaneously, a connecting plate rotates synchronously, driving a rotating nut to rotate counterclockwise. This causes the nut pair on the rotating nut to move downward, increasing the amount of fabric on the winding rod while the tensioning rods are closer together. This increases the tensioning force of the winding device, preventing wrinkles from forming when the fabric is wound, facilitating subsequent use of the fabric. However, when the winding device is in use, the motor and the driving shaft cooperate to drive the winding rod to rotate to wind the curtain fabric. However, once the winding rod has finished winding the fabric, it is difficult to quickly disassemble and assemble, making it difficult to replace the winding rod. This hinders the rapid unloading of the winding device and affects the efficiency of winding the curtain fabric. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] like Figures 1-6 As shown, a curtain fabric winding device includes a winding frame 1 and two rotating seats 7 rotatably mounted on the inner wall of the winding frame 1. A winding roller 4 is mounted between the two rotating seats 7. A motor 2 is fixed to the top of the winding frame 1 to drive one of the rotating seats 7 to rotate. Both rotating seats 7 are provided with a connecting assembly 8 for quickly releasing the winding roller 4. The winding roller 4 is provided with a notch for conveniently fixing one end of the curtain fabric.

[0027] The connecting assembly 8 includes a connecting shaft portion 81 installed at both ends of the winding roller 4, a connecting cavity 84 opened on the two rotating seats 7, and a stopper 85 inserted in the connecting cavity 84. Countersunk holes 88 are opened on both sides of the rotating seat 7, and fastening bolts 86 are screwed into the countersunk holes 88. Screw holes 89 for screwing the fastening bolts 86 are opened on both sides of the stopper 85, and one side of the stopper 85 is recessed inward to form an arc portion that contacts the outer wall of the connecting shaft portion 81.

[0028] After the curtain fabric is produced, the curtain fabric can be wound on the winding roller 4, and then the motor 2 drives one of the rotating seats 7 to rotate, so that the rotating seat 7 drives the winding roller 4 to rotate to wind the curtain fabric, thereby realizing the winding of the curtain fabric;

[0029] The stopper 85 is then pulled out of the screw hole 89 to stop the stopper 85 and the rotating seat 7, thereby completing the installation of the winding roller 4, thereby realizing the quick disassembly and assembly of the winding roller 4, facilitating the replacement of the winding roller 4, and further facilitating the quick unloading of the winding device and achieving efficient winding of the curtain fabric.

[0030] Further, if Figure 3 、 Figure 5 and Figure 6 As shown, two guide bars 87 are installed inside the connecting cavity 84, and a guide groove 810 corresponding to the two guide bars 87 is opened at the bottom of the stopper 85. Based on this, the stopper 85 and the connecting cavity 84 can be limited, which is conducive to the stable installation between the stopper 85 and the rotating seat 7.

[0031] Further, if Figure 3 and Figure 5 As shown, a snap-fit ​​strip 83 is further installed in the connecting cavity 84, and a snap-fit ​​groove 82 is provided on the connecting shaft portion 81 to cooperate with the snap-fit ​​strip 83. Based on this, the snap-fit ​​between the connecting shaft portion 81 and the connecting cavity 84 can be limited, which is conducive to the stable installation of the connecting shaft portion 81 on the rotating seat 7.

[0032] Furthermore, in order to facilitate the installation and fixation of the winding frame 1, as Figure 1 and Figure 2 As shown, a plurality of mounting slots 6 are provided at the bottom of the winding frame 1 .

[0033] At the same time, in this embodiment, Figure 1 and Figure 2 As shown, a guide member is also provided in the winding frame 1, and the guide member includes two guide rollers 3 rotatably installed in the winding frame 1, the two guide rollers 3 are symmetrically distributed on the feed side of the winding roller 4, and a channel is left between the two guide rollers 3 for the curtain fabric to pass through.

[0034] When the curtain fabric is wound, the curtain fabric passes through the channel between the two guide rollers 3 and is wound around the winding roller 4. When the winding roller 4 rotates to rewind the curtain fabric, the two guide rollers 3 guide the curtain fabric and can roll the curtain fabric to flatten it, making it smooth and avoiding wrinkles on the curtain fabric, which is conducive to the smooth winding of the curtain fabric.

[0035] In addition, in one embodiment, Figure 1 、 Figure 2 and Figure 4 As shown, a pressing assembly 5 for pressing the curtain fabric against the winding roller 4 is further provided in the winding frame 1, and the winding roller 4 includes a bracket 51 provided on the side of the winding roller 4 opposite to the guide roller 3, a pressing roller 52 is rotatably mounted on the bracket 51, and the pressing roller 52 is in contact with the winding roller 4, and a plurality of springs 53 are connected between the side of the bracket 51 opposite to the pressing roller 52 and the inner wall of the winding frame 1.

[0036] When the winding roller 4 winds up the curtain fabric, the pressure roller 52 rotates driven by the curtain fabric, and as the curtain fabric wound on the winding roller 4 continues to increase, its thickness will gradually become thicker. At this time, the curtain fabric will push the pressure roller 52, so that the pressure roller 52 presses the spring 53 through the bracket 51, and then the spring 53 contracts to drive the pressure roller 52 on the bracket 51 to move along the winding frame 1, so that the gap between the pressure roller 52 and the winding roller 4 gradually becomes larger, and under the action of the spring 53, the pressure roller 52 always presses the curtain fabric against the winding roller 4, thereby achieving the goal of pressing the curtain fabric tightly while winding it, preventing the curtain fabric from being loose, and facilitating the stable winding of the curtain fabric.

[0037] Furthermore, in order to realize the stable movement of the bracket 51 along the interior of the winding frame 1, it is convenient to stably press the curtain fabric on the winding roller 4. Figure 1 、 Figure 2 and Figure 4 As shown, a limit strip 54 is further installed on the inner wall of the winding frame 1 , and a limit slot 55 that matches the limit strip 54 is provided on the top and bottom of the bracket 51 .

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
