DETAILED DESCRIPTION

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0024] Example:

[0025] Reference Figure 1 - Figure 3 The utility model discloses a cloth spreading machine roller, comprising a base plate 1, both sides of the top of the base plate 1 are fixedly connected with support plates 2, one side of one of the support plates 2 is rotatably connected with a positioning member 4, and a positioning groove 5 for inserting the roller 3 is provided on the side of the positioning member 4 away from the support plate 2, one side of the other support plate 2 is rotatably connected with a quick-release component 6 for clamping the roller 3, and the other side is connected with a power unit 7 for driving the roller 3 to rotate.

[0026] In this embodiment, when the roller 3 needs to be replaced, the roller 3 is first pulled and squeezed to squeeze the sliding block 65 of the quick-release assembly 6, so that the sliding block 65 slides on the connecting rod 64, thereby increasing the length of the connecting rod 64 entering the slot 9, and then the roller 3 moves linearly along the length direction of the connecting rod 64 until the roller 3 is separated from the positioning member 4.

[0027] After the roller 3 is separated from the positioning member 4, a lateral force is applied to the roller 3 so that the roller 3 squeezes the connecting rod 64 to press the connecting block 62, thereby allowing the connecting block 62 to rotate in the square groove 8. At this time, the roller 3 is completely separated from the positioning member 4. Subsequently, the pulling force applied to the roller 3 is reduced to make the roller 3 move away from the connecting rod 64, and the roller 3 can be removed.

[0028] Finally, align the slot 9 of the new winding roller 3 with the connecting rod 64, and then insert the connecting rod 64 into the slot 9, and then apply a lateral force to the new winding roller 3 to reset the connecting block 62 in the square groove 8. After the resetting is completed, the axis of the new winding roller 3 coincides with the axis of the positioning member 4. At this time, release the pressure applied to the winding roller 3, and the winding roller 3 will be inserted into the positioning slot 5 under the push of the compression spring, so that the rapid replacement of the winding roller 3 can be completed. After the winding roller 3 is replaced, the motor 71 can be started, and then the transmission of the gearbox 72 can be used to control the winding roller 3 to rotate and retract the cloth.

[0029] In a further preferred embodiment of the present invention, Figure 3 As shown, the quick-release assembly 6 includes a turntable 61, a connecting block 62, a support plate 63, a connecting rod 64 and a sliding block 65. One side of the turntable 61 is rotatably connected to the support plate 2 via a rotating shaft. A square groove 8 is provided on the side of the turntable 61 away from the support plate 2. The connecting block 62 is rotatably connected in the square groove 8. The side of the connecting block 62 away from the turntable 61 is fixedly connected to the support plate 63. The side of the support plate 63 away from the connecting block 62 is fixedly connected to the connecting rod 64. The outer wall of the connecting rod 64 is slidably connected to the sliding block 65. A compression spring is provided between the sliding block 65 and the support plate 63.

[0030] In this embodiment, the square groove 8 is provided so that the connecting block 62 and the turntable 61 can rotate, so that the angle of the roller 3 can be adjusted during installation and disassembly, so that the roller 3 is staggered with the positioning member 4 during loading and unloading, avoiding the collision of the roller 3 with the positioning member 4 during installation, reducing the difficulty of installing the roller 3, and improving the replacement efficiency of the roller 3.

[0031] At the same time, a sliding block 65 is connected to the connecting rod 64, and a compression spring is arranged between the sliding block 65 and the supporting plate 63. The compression spring can push the sliding block 65 to fit tightly against and squeeze the roller 3 to limit the movement of the roller 3, thereby ensuring the stability of the roller 3 after installation.

[0032] In a further preferred embodiment of the present invention, Figure 2 As shown, one end of the roller 3 is provided with a slot 9 for inserting the connecting rod 64, and the depth of the slot 9 is A;

[0033] The sum of the length of the connecting rod 64 and the depth of the positioning groove 5 is B;

[0034] A is greater than B.

[0035] In this embodiment, because the winding roller 3 needs to avoid the positioning member 4 during loading and unloading to prevent the positioning member 4 from interfering with the installation of the winding roller 3, it is necessary to ensure that after the connecting rod 64 is inserted into the slot 9, the distance from the sliding block 65 to the other end of the winding roller 3 is smaller than the distance between the sliding block 65 and the positioning member 4; and in order to ensure the stability of the winding roller 3 after the installation is completed, the distance between the end point of the connecting rod 64 and the positioning groove 5 must be smaller than the length of the winding roller 3, so the depth of the slot 9 opened on the winding roller 3 must be greater than the sum of the length of the connecting rod 64 and the depth of the positioning groove 5, so that when the connecting rod 64 is fully inserted into the slot 9, a gap for installation is retained between the winding roller 3 and the positioning member 4, and when the winding roller 3 is inserted into the positioning groove 5, the connecting rod 64 will not be separated from the winding roller 3.

[0036] In addition, the slot 9 is arranged on one end surface of the roller 3 , and the flat end surface can effectively reduce the processing difficulty of the roller 3 and reduce the processing cost of the slot 9 , thereby improving the production efficiency of the roller 3 and reducing the difficulty of mass production of the roller 3 .

[0037] In a further preferred embodiment of the present invention, Figure 3 As shown, a circular groove 10 is provided on the inner wall of the square groove 8, a positioning block 11 is slidably connected inside the circular groove 10, a supporting spring is provided between the positioning block 11 and the circular groove 10, and a clamping groove 12 for clamping the positioning block 11 is provided on the outer wall of the connecting block 62.

[0038] In this embodiment, a circular groove 10 is provided in the square groove 8, and a positioning block 11 is connected to the circular groove 10 through a supporting spring. At the same time, a clamping groove 12 for clamping the positioning block 11 is provided on the side wall of the connecting block 62. This can assist in positioning when installing the winding roller 3, so that when the axis of the winding roller 3 coincides with the turntable 61, the positioning block 11 clamps the clamping groove 12, thereby assisting the installation and further reducing the difficulty of installing the winding roller 3.

[0039] In a further preferred embodiment of the present invention, Figure 3 As shown, the connecting rod 64 is a prism.

[0040] In this embodiment, because the connecting rod 64 is fixedly connected to the support disk 63, and the support disk 63 is connected to the turntable 61 through the connecting block 62, when the motor 71 drives the gearbox 72 to drive the turntable 61 to rotate, the connecting rod 64 will also rotate accordingly. Therefore, in order to ensure that the connecting rod 64 can drive the winding roller 3 to rotate and rewind the fabric when it rotates, the connecting rod 64 is a prism, so that when the connecting rod 64 is inserted into the slot 9, the side wall of the connecting rod 64 can squeeze the side wall of the slot 9 to drive the winding roller 3 to rotate.

[0041] In a further preferred embodiment of the present invention, Figure 1As shown, both ends of the winding roller 3 are fixedly connected to limit plates 13 .

[0042] In this embodiment, by setting a limit plate 13 on the side wall of the winding roller 3, the cloth can be limited by the limit plate 13 to prevent the cloth from deviating and wrinkling when the cloth is rolled up, thereby affecting the quality of the cloth. At the same time, the setting of the limit plate 13 can also protect the cloth and prevent the cloth from being squeezed and wrinkled.

[0043] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
