DETAILED DESCRIPTION

[0021] 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 making creative efforts are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figure 1-4The utility model provides a technical solution: a valve bag winding machine, comprising a device body 1 and a frame 4; the frame 4 is installed at one end of the device body 1, a protection mechanism 2 is provided at one end of the frame 4, and an auxiliary mechanism 3 is provided on the side of the frame 4; the protection mechanism 2 comprises two mounting platforms 21 mounted at one end of the frame 4, a movable groove 22 is provided in the mounting platform 21, a movable block 23 is installed in the movable groove 22, a second spring 24 is installed at both ends of the movable block 23, a rotating column 25 is installed on the side of the movable block 23, and the rotating column 2 5 is installed on the side of the winding roller 26, a sliding groove 27 is opened on the side of the mounting platform 21, a slider 28 is slidably installed in the sliding groove 27, one end of the slider 28 is installed with a mounting plate 29, a conveyor belt 5 is installed on the frame 4, one end of the conveyor belt 5 is installed with a fixed base 6, one end of the fixed base 6 is installed with a first motor 7 adapted to the conveyor belt 5, the mounting plate 29 is slidably installed on the side of the mounting platform 21, one end of the mounting plate 29 is installed with a second motor 8, the second motor 8 is adapted to the rotating column 25, one end of the winding roller 26 A clamping groove 9 is provided, and a clamping strip 10 is installed in the clamping groove 9. Both ends of the clamping groove 9 are provided with a first spring 11. One end of the clamping strip 10 is provided with a pulling groove 12. When the valve bag needs to be rolled up, one end of the valve bag needs to be clamped on the side of the winding roller 26. The clamping strip 10 is pulled through the pulling groove 12 to drive the first spring 11 to pull up, and a section of the valve bag is placed in the clamping groove 9. After releasing the pulling groove 12, the first spring 11 rebounds and mobilizes the clamping strip 10 to clamp the valve bag, so that it can be wound around the side of the winding roller 26 when rolling up to start the first spring 11. A motor 7 and a second motor 8 place the valve bag on the conveyor belt 5 for transmission. When the valve bag is wound by the winding roller 26, the winding radius of the winding roller 26 increases with time, and the pulling force on the valve bag increases. At this time, the movable block 23 can slide in the movable groove 22 and squeeze the second spring 24, so that the winding roller 26 can generate a certain tension when winding, protecting the valve bag from being damaged due to hard pulling. The slider 28 slides in the slide groove 27 and drives the second motor 8 to move with the winding roller 26, thereby improving production efficiency.

[0023] The working principle is as follows: when the valve bag needs to be rolled up, one end of the valve bag needs to be clamped on the side of the winding roller 26, and the clamping strip 10 is pulled by the groove 12 to drive the first spring 11 to pull up, and a section of the valve bag is placed in the clamping groove 9. After the groove 12 is released, the first spring 11 rebounds and the clamping strip 10 is mobilized to clamp the valve bag so that it can be wound around the side of the winding roller 26 when rolled up. The first motor 7 and the second motor 8 are started, and the valve bag is placed on the conveyor belt 5 for transmission. The valve bag is straightened by the guidance of the guide plate 37. When it is transmitted to the position of the rotating disk 36, the valve bag is squeezed by the side of the rotating disk 36 and the conveyor belt 5 to discharge excess air and fold it. Rotating the pressure roller 35 causes the screw rod 34 to rotate, and then the connecting block 33 is adjusted to slide in the movable chamber 32, adjusting the distance between the rotating disk 36 and the conveyor belt 5 to adapt to valve bags of different specifications. When the valve bag is wound by the winding roller 26, as time goes by, the winding radius of the winding roller 26 becomes larger, and the pulling force on the valve bag increases. At this time, the movable block 23 can slide in the movable groove 22 and squeeze the second spring 24, so that the winding roller 26 can generate a certain tension when winding, protecting the valve bag from damage due to hard pulling. The slider 28 slides in the slide groove 27 and drives the second motor 8 to move with the winding roller 26, maintaining the stability of winding and improving production efficiency.

The guide plate 37 is rotatably mounted on the frame 4, and one end of the limit bolt 38 is threadedly mounted on the frame 4. The valve bag is straightened by the guidance of the guide plate 37. When it is transmitted to the position of the rotating disk 36, the valve bag is squeezed by the side of the rotating disk 36 and the conveyor belt 5 to discharge excess air and fold it. The pressure roller 35 can be rotated to adjust the screw rod 34 to rotate, and then the connecting block 33 can be adjusted to slide in the movable cavity 32, and the distance between the rotating disk 36 and the conveyor belt 5 can be adjusted to adapt to valve bags of different specifications.
