DETAILED DESCRIPTION

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example

[0025] A sofa fabric winding machine, such as Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 and Figure 6 As shown, it includes a bracket 1, a feed roller 2, a transmission roller 5, a winding roller 6 and a limiting mechanism. A feed roller 2 is provided inside the bracket 1, and a transmission roller 5 is symmetrically provided in the front and back of the bracket 1. A winding roller 6 is rotatably provided on the upper part of the bracket 1 to facilitate winding of the fabric. A snap-in hole 601 is provided on the right side of the winding roller 6, and a limiting mechanism is provided on the first connecting rod 7.

[0026] like Figure 1 、 Figure 2 、 Figure 5 and Figure 7 As shown, it also includes a first transition roller 3, a second transition roller 4, a pressure roller 13 and a second connecting rod 14. The first transition roller 3 is installed on the upper front side of the bracket 1, and the second transition roller 4 is installed on the upper front side of the bracket 1. The second transition roller 4 is located on the rear side of the first transition roller 3. A second connecting rod 14 is provided inside the bracket 1, and the two second connecting rods 14 are symmetrically connected with pressure rollers 13 above and below, which can press the fabric.

[0027] When the staff needs to use this device, the staff first pulls one end of the fabric to the bottom of the feed roller 2, and then pulls the fabric from under the feed roller 2 to under the pressure roller 13, and the fabric is then wound out from between the two pressure rollers 13. The staff pulls the fabric around the first transition roller 3 again, and the fabric is pulled from above the first transition roller 3 to under the second transition roller 4, and the fabric is pulled from under the second transition roller 4 to above the transmission roller 5. The staff then pulls the fabric from above the transmission roller 5 to between the two transmission rollers 5, and the fabric is then wound out from between the two transmission rollers 5, so that the fabric is wound around the winding roller 6. Then the staff pulls the fabric to wrap around the winding roller 6. After the fabric is wound, the staff loosens the fabric, and then the staff rotates the winding roller 6, so that the winding roller 6 rotates to wind up the fabric. After the fabric is wound, the staff no longer rotates the winding roller 6, and the staff repeats the above operation, which facilitates the winding of the fabric and thus improves the winding efficiency of the fabric. Example

[0028] On the basis of Example 1, Figure 2 、 Figure 3 and Figure 5 As shown, the limiting mechanism includes a first connecting rod 7, a limiting plate 8 and a first spring 9. The bracket 1 is symmetrically connected to the first connecting rod 7 on both sides. A limiting plate 8 is slidably provided on the first connecting rod 7 to limit the length of the fabric. The limiting plate 8 is U-shaped. The first connecting rod 7 is sleeved with a first spring 9. One end of the first spring 9 is connected to the limiting plate 8, and the other end of the first spring 9 is connected to the first connecting rod 7.

[0029] Before winding the fabric, when the staff needs to limit fabrics of different lengths, the staff first pulls the limit plate 8 and moves it outward along the winding roller 6. During the movement of the limit plate 8, the limit plate 8 moves outward along the first connecting rod 7, and the first spring 9 is compressed. Then the staff pulls the fabric to be wound onto the winding roller 6. After the fabric is wound, the staff releases the limit plate 8. Under the reset action of the first spring 9, the limit plate 8 moves inward along the first connecting rod 7. At the same time as the limit plate 8 moves, the limit plate 8 moves inward along the winding roller 6. The limit plate 8 contacts the fabric and limits it, which is convenient for limiting fabrics of different lengths, thereby preventing uneven winding of the fabric during winding.

[0030] like Figure 2 and Figure 3As shown, it also includes a motor 10, a polygonal shaft 1001 and a second spring 11. The motor 10 is slidably provided on the first connecting rod 7, and the polygonal shaft 1001 is connected to the output shaft of the motor 10 to facilitate clamping the clamping hole 601. The second spring 11 is sleeved on the first connecting rod 7, one end of the second spring 11 is connected to the motor 10, and the other end of the second spring 11 is connected to the first connecting rod 7.

[0031] During the process of winding the fabric, the staff starts the motor 10, the output shaft of the motor 10 drives the polygonal shaft 1001 to rotate, the polygonal shaft 1001 drives the engaging hole 601 to rotate, and the engaging hole 601 drives the winding roller 6 to rotate, so as to roll the fabric faster. After the fabric is rolled up, the staff can turn off the motor 10. Then when the staff needs to take down the rolled fabric, the staff pulls the motor 10 to move to the right along the first connecting rod 7, the output shaft of the motor 10 drives the polygonal shaft 1001 to move to the right, the second spring 11 is compressed, and the polygonal The shaft 1001 no longer clamps the clamping hole 601, and then the staff lifts the winding roller 6 to make the fabric easier to remove. After the fabric is removed, the staff lifts the winding roller 6 back to its original position and releases the motor 10. Under the reset action of the second spring 11, the motor 10 moves to the left along the first connecting rod 7. The output shaft of the motor 10 drives the polygonal shaft 1001 to move to the left. The polygonal shaft 1001 contacts the clamping hole 601 and clamps it, which makes it easier to remove the fabric and replace the winding roller 6 when it needs to be replaced.

[0032] like Figure 5 、 Figure 6 and Figure 7 As shown, it also includes a rotating handle 12, a latch 15 and a third spring 16. The rotating handle 12 is rotatably provided on the left side of the pressure roller 13. The staff can rotate the rotating handle 12 to drive the second connecting rod 14 to rotate. The rotating handle 12 passes through the bracket 1. The left side of the rotating handle 12 is slidably provided with a latch 15, which can clamp the socket 101. The third spring 16 is sleeved on the latch 15. One end of the third spring 16 is connected to the rotating handle 12, and the other end of the third spring 16 is connected to the latch 15. A socket 101 is opened on the left side of the bracket 1. The latch 15 slides with the socket 101, and the number of sockets 101 is not less than five.

[0033] When the fabric is rolled up, the staff needs to press the fabric tightly, and then the staff pulls the latch 15 to move to the left along the rotating handle 12, the third spring 16 is compressed, and the latch 15 no longer jams the socket 101, and then the staff turns the rotating handle 12 to drive the second connecting rod 14 to rotate, and the second connecting rod 14 drives the pressing roller 13 to rotate, and the rotation of the pressing roller 13 drives the fabric to rotate, so that the fabric becomes tighter and tighter. When the fabric is rolled up, the staff stops turning the rotating handle 12, and then the staff releases the latch 15. Under the resetting action of the third spring 16, the latch 15 moves to the right along the rotating handle 12, and the latch 15 contacts and jams the socket 101, thereby facilitating the compression of the fabric, and thus enabling the fabric to be rolled up more evenly.

Personnel familiar with the art may make various modifications or changes to the above embodiments without departing from the utility model concept of the present invention.
