It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a winding device for a bag making machine, comprising: a bottom plate 1, a fixing seat 3 is fixedly connected to the top of the bottom plate 1, and a feeding rack 6 is fixedly connected to the side of the top of the bottom plate 1 away from the fixing seat 3; a tensioning assembly 2, the tensioning assembly 2 is fixedly connected to the top of the bottom plate 1, the tensioning assembly 2 comprises a bracket 201, a bolt 202 is threadedly connected to the top of the bracket 201, a connecting seat 203 is rotatably connected to the lower end surface of the bolt 202, a pressure sensor 205 is fixedly connected to the bottom of the connecting seat 203, a support 208 is arranged inside the connecting seat 203, a support shaft 210 is rotatably connected to the inner surface of the support shaft 210, a pressure roller 211 is fixedly connected to the outer surface of the supporting seat 3, a motor 4 is fixedly connected to the outer surface of the fixing seat 3, an output end of the motor 4 passes through the fixing seat 3 and extends to the front side, a winding roller 5 is fixedly connected to the output end of the motor 4, and a feeding rack 6 is fixedly connected to the outer surface of the fixing seat 3. The inner surface of the frame 6 is symmetrically rotatably connected with a connecting rod 7, and electrostatic dust removal rollers 8 are arranged on the outer surfaces of the two connecting rods 7. The electrostatic dust removal rollers 8 are at the same height as the winding roller 5. The top of the connecting seat 203 is symmetrically fixedly connected with a limit rod 204, and the limit rod 204 slides through and extends to the upper side with the connecting seat 203. The pressure roller 211 is located at the lower side of the connecting seat 203, and the connecting seat 203 matches the position of the pressure sensor 205. The top of the bracket 201 is fixedly connected with a display screen 212, and the display screen 212 is electrically connected to the pressure sensor 205. The inner surfaces of both sides of the connecting seat 203 are fixedly connected with slide rails 206, and the outer surfaces of the slide rails 206 are slidably connected with sliders 207, and the sliders 207 are fixedly connected to the connecting seat 203. The bottom of the connecting seat 203 is symmetrically fixedly connected with baffles 209, and the positions of the baffles 209 and the sliders 207 match.

[0024] The effect achieved by the entire embodiment 1 is that after the bag making machine completes the production of the plastic bag, the plastic bag is rolled up. After the plastic bag is pulled out of the bag making machine, it passes between the two electrostatic dust removal rollers 8, then passes through the bottom position of the pressure roller 211 and is wound around the winding roller 5. The starting motor 4 can drive the winding roller 5 to rotate to roll up the plastic bag. While rolling up, the plastic bag passes under the pressure roller 211. At this time, in order to ensure that the plastic bag is rolled up in a tensioned state, tightening the bolt 202 can drive the connecting seat 203 to move downward. The setting of the limit rod 204 can limit the movement of the connecting seat 203. After the connecting seat 203 moves downward, it can drive the pressure roller 211 to follow the downward movement to apply pressure to the surface of the plastic bag. After the surface of the plastic bag is subjected to pressure during the rolling process, the plastic bag can be tightened, thereby ensuring that the plastic bag is tightly rolled up. During winding, while the pressure roller 211 is used to apply pressure to the plastic bag, the pressure on the plastic bag will be transmitted to the position of the pressure roller 211 through the reaction force. The pressure roller 211 transmits the pressure to the top pressure sensor 205 through the connection between the support shaft 210 and the support 208. The support 208 is limited by the cooperation of the slide rail 206 and the slider 207 to ensure that the support 208 applies a vertical upward force to the pressure sensor 205. At this time, the pressure data detected by the pressure sensor 205 will be displayed on the display screen 212. The staff can know the pressure data of the plastic bag at this time by reading the display screen 212. According to the material strength of the plastic bag, the bolt 202 can be turned to adjust the tightening pressure data of the plastic bag to avoid deformation or rupture of the plastic bag when the plastic bag is tightened for winding, thereby effectively improving the processing quality of the bag making machine.

[0025] Embodiment 2, as Figure 1-Figure 4 As shown, the inner surface of the feed rack 6 is symmetrically rotatably connected with a connecting rod 7, and the outer surfaces of the two connecting rods 7 are provided with electrostatic dust removal rollers 8.

[0026] The effect achieved by the entire embodiment 2 is that when the plastic bag passes between the electrostatic dust removal rollers 8 on both sides during the winding process, the plastic bag contacts the electrostatic dust removal rollers 8 to cause them to rotate. The electrostatic dust removal rollers 8 can absorb the dust on the surface of the plastic bag, thereby preventing the plastic bag from being affected in product quality due to the adhesion of dust after winding.

[0027] Working principle: after the bag making machine has completed the production of the plastic bag, the plastic bag is rolled up. After the plastic bag is pulled out of the bag making machine, it passes between the two electrostatic dust removal rollers 8, then passes through the bottom position of the pressure roller 211 and is wound around the winding roller 5. Starting the motor 4 can drive the winding roller 5 to rotate to roll up the plastic bag. While rolling up, the plastic bag passes through the lower position of the pressure roller 211. At this time, in order to ensure that the plastic bag is rolled up in a tensioned state, tightening the bolt 202 can drive the connecting seat 203 to move downward. The setting of the limit rod 204 can limit the movement of the connecting seat 203. After the connecting seat 203 moves downward, it can drive the pressure roller 211 to follow the downward movement to apply pressure to the surface of the plastic bag. After the surface of the plastic bag is subjected to pressure during the rolling process, the plastic bag can be tightened, thereby ensuring that the plastic bag is tightly rolled up. While the pressure roller 211 is used to apply pressure to the plastic bag, the pressure on the plastic bag will be transmitted to the pressure roller through the reaction force. The roller 211 is in the position, and the pressure roller 211 transmits the pressure to the top pressure sensor 205 through the connection between the support shaft 210 and the support 208. The support 208 is limited by the cooperation of the slide rail 206 and the slider 207 to ensure that the support 208 applies a vertical upward force to the pressure sensor 205. At this time, the pressure data detected by the pressure sensor 205 will be displayed on the display screen 212. The staff can read the pressure data of the plastic bag at this time through the display screen 212. According to the material strength of the plastic bag, the bolt 202 can be turned to adjust the tensioning pressure data of the plastic bag to avoid deformation or rupture of the plastic bag when the plastic bag is tightened and rolled. When the plastic bag passes between the electrostatic dust removal rollers 8 on both sides during the rolling process, the plastic bag contacts the electrostatic dust removal rollers 8 to make it rotate. The electrostatic dust removal rollers 8 can absorb dust on the surface of the plastic bag to avoid the adhesion of dust to the plastic bag after rolling. The product quality is affected.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
