DETAILED DESCRIPTION

[0024] The following is a combination of specific implementation cases and attached Figures 1 to 4 The present invention is further described below, but the present invention is not limited to these embodiments.

[0025] The existing woven bag traction and reeling device is mostly set as a single support bracket, but lacks the limit function of the free end of the woven bag. After the free end of the woven bag is cut off, it will float in the air, causing the woven bag wrapped around the outermost circle of the reel to loosen, affecting the subsequent reeling and use of the woven bag. Figures 1 to 4 As shown, a traction and winding device for woven bag production is proposed, including a supporting component, a woven bag 4 is rotatably provided on the top of the supporting component, the woven bag 4 is supported and positioned by the supporting component, two frames 5 are provided on the right side of the supporting component, and a first cylinder 7 is installed on the top of each frame 5. The first cylinder 7 is a self-locking cylinder commonly used on the market, and its output end can stay in any position and be locked, which is not described in detail here. A supporting plate 8 is installed on the top of the two first cylinders 7, and a limiting component for limiting the free end of the woven bag 4 is provided on the top of the supporting plate 8. The free end of the woven bag 4 is limited by the limiting component, and the limiting component includes a first limiting seat 12, and a second limiting seat 13 is rotatably installed on the top of the first limiting seat 12 for flipping and buckling. Specifically, the first limiting seat 12 and the second limiting seat 13 are rotated and fastened. The rear sides of the two limit seats 13 are rotatably connected, and the front sides of the first limit seat 12 and the second limit seat 13 are connected by bolts. By removing the bolts, the first limit seat 12 and the front sides of the second limit seat 13 can lose the lock, and then the second limit seat 13 can be flipped backward to realize the opening between the first limit seat 12 and the second limit seat 13. The top end of the first limit seat 12 is rotatably provided with a plurality of first limit rollers 14, and the bottom end of the second limit seat 13 is rotatably provided with a plurality of second limit rollers 15. The first limit rollers 14 and the second limit rollers 15 are respectively provided with three, and each second limit roller 15 corresponds to the position of each first limit roller 14 up and down. The free end of the woven bag 4 passes through the gap between the first limit roller 14 and the second limit roller 15 from left to right;

[0026] The screws on the front sides of the first limit seat 12 and the second limit seat 13 are removed, and the second limit seat 13 is flipped backward to make the second limit seat 13 open relative to the first limit seat 12, and the free end of the woven bag 4 is placed on the upper surface of the first limit roller 14 in the inner cavity of the first limit seat 12, and then the second limit seat 13 is flipped forward to make the second limit seat 13 reset, and the second limit seat 13 and the first limit seat 12 are reconnected and fixed with the help of screws. At this time, the free end of the woven bag 4 is clamped under the limiting action of the first limit roller 14 and the second limit roller 15. When the woven bag 4 is rolled up, the free end of the woven bag 4 moves between the first limit roller 14 and the second limit roller 15, causing the first limit roller 14 and the second limit roller 15 to rotate relative to each other. During the rotation of the first limit roller 14 and the second limit roller 15, the free end of the woven bag 4 is still rolled and limited to ensure the stability of the free end of the woven bag 4 after being cut off.

[0027] See also Figure 3 As shown, a fixed seat 6 is installed at the top of the frame 5, and a limit rod 9 is set on the outer wall of the fixed seat 6 to slide from top to bottom, and the top of the limit rod 9 is fixedly connected to the bottom end of the outer wall of the support plate 8. When the output end of the first cylinder 7 drives the support plate 8 to move up and down, it can prompt the limit rod 9 to move along the outer wall of the fixed seat 6 to further limit the movement of the support plate 8 in the vertical direction.

[0028] See also Figure 2 As shown, a rotating shaft 10 is rotatably installed in the inner cavity of the support plate 8 through a bearing, and connecting arms 11 are fixedly installed on the front and rear sides of the outer wall of the rotating shaft 10, and the top of the connecting arm 11 is fixedly connected to the bottom end of the first limit seat 12. By driving the rotating shaft 10 to rotate, the first limit seat 12 and the second limit seat 13 and the output end of the positioned woven bag 4 can be synchronously rotated and adjusted; the front end of the rotating shaft 10 extends out of the outer wall of the support plate 8 and is installed with a gear 16, and a second cylinder 17 is installed on the front side of the outer wall of the support plate 8. The second cylinder 17 is a self-locking cylinder commonly used on the market, and its output end can stay at any position and lock , which will not be described in detail here. The output end of the second cylinder 17 is connected to a rack 18, and the rack 18 is meshed with the outer wall of the gear 16. The output end of the second cylinder 17 is opened to drive the rack 18 to move, so as to realize the rotation of the gear 16, so as to drive the rotating shaft 10 to rotate; a slide groove 19 is provided on the front side of the outer wall of the support plate 8 in the horizontal direction, and a slider 20 is slidably embedded in the inner cavity of the slide groove 19. The slider 20 is fixedly connected to the rear side of the outer wall of the rack 18. When the rack 18 moves, it can drive the slider 20 to slide along the inner cavity of the slide groove 19 to ensure that the rack 18 moves in the horizontal direction without tilting;

[0029] When the height of the free end of the woven bag 4 positioned between the first limiting roller 14 and the second limiting roller 15 is adjusted: the first cylinder 7 is turned on to cause the support plate 8 to move, so as to cause the rotating shaft 10 and the connecting arm 11 in the inner cavity of the support plate 8 to move synchronously, and the first limiting seat 12 and the second limiting seat 13 at the top of the connecting arm 11 and the positioned free end of the woven bag 4 can be adjusted in height;

[0030] When the inclination angle of the free end of the woven bag 4 positioned between the first limiting roller 14 and the second limiting roller 15 is adjusted: the rack 18 is prompted to move by the opened second cylinder 17, so as to prompt the slider 20 connected to the rear side of the outer wall of the rack 18 to move along the inner cavity of the slide groove 19. At this time, the gear 16 meshingly connected to the outer wall of the rack 18 rotates, prompting the rotating shaft 10 to rotate, so as to realize the adjustment of the inclination angle of the connecting arm 11, the first limiting seat 12, the second limiting seat 13 and the positioned free end of the woven bag 4.

[0031] See also Figure 1 As shown, the supporting component includes a base 1, a supporting arm 2 is vertically installed on the left side of the top of the base 1, a reel 3 is rotatably arranged on the top of the supporting arm 2, a woven bag 4 is wound around the outer wall of the reel 3, and the reel 3 is rotatably arranged on the top of the supporting arm 2. The reel 3 can be supported by the supporting arm 2 while ensuring that the normal rotation of the woven bag 4 will not be restricted.

[0032] See also Figure 1 As shown, the frame 5 is configured to be L-shaped, the left side of the frame 5 is fixedly mounted on the right side wall of the support arm 2, and the bottom end of the frame 5 is fixedly mounted on the upper surface of the base 1 to ensure that the frame 5 realizes the connection between the support arm 2 and the base 1, and at the same time realizes the support positioning of the fixed seat 6.

[0033] The utility model sets a limiting function for the free end of the woven bag 4, so as to avoid the problem that the free end of the woven bag 4 is loose on the outer wall of the reel 3 after being cut off. The woven bag 4 after being cut off can continue to be used without re-adjusting the position of the outermost circle of the woven bag, which is more conducive to the rapid and effective production of the woven bag. The rotatable first limiting roller 14 and the second limiting roller 15 will not affect the normal winding and movement of the woven bag 4, and the normal use requirements of the woven bag 4 can be met while limiting the free end of the woven bag 4. In addition, after positioning, the height and inclination angle of the first limiting roller 14 and the second limiting roller 15 can be adjusted, so that the equipment can flexibly meet the processing requirements of woven bag production equipment of different heights and angles.
