[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] like Figure 1-2 As shown, a winding device for producing ton bag slings includes a vertically arranged vertical plate 3, a horizontally arranged and rotatable main shaft 9 is installed on the vertical plate 3, a positioning plate 7 is detachably installed at the end of the main shaft 9, and a limiting pad 6 is installed on the surface of the positioning plate 7 close to the vertical plate 3. The main function of the limiting pad 6 is to compensate for the gap between the end of the reel 11 and the positioning plate 7. It is installed on the surface of the positioning plate 7 by means of screws. On the one hand, it is used to limit the axial movement of the reel 11 on the main shaft 9, and on the other hand, it is used to cooperate with the vertical plate 3 to limit the deflection of the sling during the reeling process. The thickness of the limiting pad 6 can be selected according to the actual length of the reel 11, so as to adapt to the reeling work of slings of different widths.

[0018] A reel 11 is installed on the main shaft 9 between the limit pad 6 and the vertical plate 3. The reel 11 is installed on the main shaft 9 in the form of a key bar and rotates with the main shaft 9. A pressing wheel 5 that can move up and down is installed on the vertical plate 3 and above the reel 11.

[0019] The surface of the vertical plate 3 is provided with a groove 13 in the vertical direction, and a slider 14 is slidably installed in the groove 13. A connecting rod 4 arranged in the horizontal direction and extending to the position between the vertical plate 3 and the limiting pad 6 is installed on the slider 14, and a pressing wheel 5 is rotatably installed at the end of the connecting rod 4. More specifically, a guide rod 15 arranged in the vertical direction is installed in the groove 13 on the surface of the vertical plate 3. The slider 14 is sleeved on the guide rod 15 and slidably cooperates with the guide rod 15. A spring is sleeved on the guide rod 15 between the slider 14 and the top wall of the groove 13, one end of the spring is connected to the top wall position of the groove 13, and the other end is connected to the upper end of the slider 14. In the actual process of winding up the sling, the pressing wheel 5 can contact with the sling, thereby pressing the sling during the winding process, so that the winding belt is compacted. The pressing wheel 5 can be connected to the connecting rod 4 in a bearing connection manner, or a bearing can be directly used as the pressing wheel 5, so as to convert traditional sliding friction into rolling friction, avoid the problem of indentation or damage on the surface of the sling, and improve product quality.

[0020] The end of the main shaft 9 has a shoulder portion 10 in contact with the positioning disk 7, and a spring plunger 8 is installed on the positioning disk 7. The axis of the spring plunger 8 is perpendicular to the axis of the positioning disk 7, and one end of the spring plunger 8 extends to the center hole of the positioning disk 7. The main shaft 9 is provided with a groove matching the spring plunger 8. The shoulder portion 10 can be used to limit the installation position of the positioning disk 7, so that the positioning disk 7 can be installed in the same position each time, so that the steel ball at the front end of the spring plunger 8 is conveniently inserted into the groove of the main shaft 9 to realize the positioning of the positioning disk 7. When the winding work is completed, the positioning disk 7 and the limit pad 6 can be disassembled by simply pulling the positioning disk 7 outward, which replaces the traditional threaded connection method, which is convenient and quick.

[0021] A horizontal base 1 is installed below the vertical plate 3 , a motor 2 is fixed to the outer side of the vertical plate 3 , and a main shaft 9 is installed on the output shaft of the motor 2 .

[0022] When in use, the winding device for the production of ton bag slings utilizes the motor 2 to drive the main shaft 9 to rotate, thereby causing the reel 11 on the main shaft 9 to rotate, and the sling is wound during the rotation of the reel 11. During winding, the pressing wheel 5 can gradually contact the sling. When the winding radius gradually increases, the pressing spring 12 is compressed, and the force applied to the sling also gradually increases, thereby achieving the effect of winding and compacting. After the winding is completed, the positioning disk 7 is pulled outward, so that the reel 11 and the rolled sling can be removed from the main shaft 9 together, and then the new reel 11 is reloaded into the main shaft 9. After the positioning disk 7 is installed in place, the winding of the next reel 11 is carried out.

[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
