However, the plastic bags need to maintain a stable discharge during production, and it takes a certain amount of time to replace the reel. Therefore, when replacing the reel, plastic bags of a certain length cannot be rolled up and fall to the ground, causing certain pollution to the processed plastic bags and also affecting the reeling efficiency of the plastic bags.

DETAILED DESCRIPTION

[0019] The following is combined with Figure 1-4 This application is described in further detail.

[0020] The present application embodiment discloses a packaging material production device. Figure 1-4 A packaging material production equipment comprises a support base 1, a support frame 2 is symmetrically fixedly connected to the upper surface of the support base 1, a shaft bracket 3 is rotatably installed in the middle of one side of the support frame 2, a plurality of hollow rotating shafts 4 are hinged on one side edge of the shaft bracket 3, a winding frame 5 is movably installed between two hollow rotating shafts 4 symmetrically on the left and right, a fixing rod 6 is welded to the inside of the hollow rotating shaft 4 on both sides of the winding frame 5, a spline shaft 7 is installed on one side of the single hollow rotating shaft 4 through the outside of the shaft bracket 3, and a placing table 8 is arranged near the spline shaft 7 on the upper surface of the support base 1 A fixed guide rail 9 is fixedly installed on one side edge of the top of the placing table 8, and a cylinder 12 is installed in the middle of the other side of the top of the placing table 8. The output end of one side of the cylinder 12 is placed on the upper surface of the fixed guide rail 9, and a driving motor 10 is installed on one side of the driving motor 10. A spline sleeve 11 is installed at the output end of one side of the driving motor 10. A spline groove is opened in the middle of one side of the spline sleeve 11, and one side edge of the spline shaft 7 is located inside the spline groove. The spline shaft 7 and the spline sleeve 11 are coupled to each other. A fixing mechanism is also provided on the outer surface of the hollow rotating shaft 4 for fixing the fixing rod 6 inside the hollow rotating shaft 4.

[0021] By fixing the winding frame 5 between the two hollow rotating shafts 4, starting the cylinder 12 drives the driving motor 10 to move along the upper surface of the fixed guide rail 9, so that the driving motor 10 moves and drives the spline sleeve 11 to clamp the outer surface of the spline shaft 7 at the corresponding position, starting the driving motor 10 to drive the spline sleeve 11 to rotate, so that the hollow rotating shaft 4 rotates as a whole and drives the winding frame 5 to rewind the plastic bag. At the same time, the winding frame 5 that has been rolled up on the hollow rotating shaft 4 at other positions is removed, which reflects the alternating replacement and rewinding effect of the shaft bracket 3.

[0022] Reference Figure 2 and Figure 4The fixing mechanism includes a fixing groove 13, which is equidistantly arranged at one side edge of the hollow shaft 4. An elastic block 14 is welded inside the fixing groove 13. An external thread 15 is arranged on the outer surface of the hollow shaft 4 near the elastic block 14. A limiting sleeve 16 is movably installed on the outer surface of the external thread 15. An internal thread is arranged on one side edge of the inner wall of the limiting sleeve 16. The external thread 15 and the internal thread are adapted to each other. The other side of the inner wall of the limiting sleeve 16 abuts against the outer surface of the elastic block 14. The outer surface of the elastic block 14 abuts against the fixing rod 6. The limiting sleeve 16 and the fixing rod 6 are both engaged with the elastic block 14.

[0023] By placing the winding frame 5 between the two hollow rotating shafts 4, the fixing rod 6 is inserted into the hollow rotating shaft 4, and the rotating limit sleeve 16 moves along the outer surface of the external thread 15, so that one side edge of the limit sleeve 16 is squeezed close to the elastic block 14, and then the elastic block 14 is squeezed on the fixing rod 6, so that multiple elastic blocks 14 limit and fix the winding frame 5, which reflects the disassembly and assembly effect of the winding frame 5 on the hollow rotating shaft 4.

[0024] Reference Figure 1 and Figure 3 A limiting column 17 is installed on the outside of the support frame 2 through the middle of one side of the other shaft bracket 3. A fixing sleeve 18 is welded on the outer surface of the support frame 2 outside the limiting column 17. The outer surface of the fixing sleeve 18 is symmetrically threaded with a limiting bolt 19, and one side edge of the limiting bolt 19 abuts against the outer surface of the limiting column 17.

[0025] The rotating shaft bracket 3 drives the limiting column 17 to rotate synchronously. After the position of the shaft bracket 3 is adjusted, the rotating limiting bolt 19 passes through the fixing sleeve 18 and abuts against the limiting column 17, thereby limiting and fixing the adjusted shaft bracket 3, which reflects the overall stability of the shaft bracket 3 when in use.

[0026] The implementation principle of a packaging material production equipment in an embodiment of the present application is as follows: by placing the winding frame 5 between the two hollow rotating shafts 4, the fixing rod 6 is inserted into the hollow rotating shaft 4, and the limiting sleeve 16 is rotated to move along the outer surface of the external thread 15, so that one side edge of the limiting sleeve 16 is squeezed close to the elastic block 14, and then the elastic block 14 is squeezed on the fixing rod 6, so that multiple elastic blocks 14 limit and fix the winding frame 5, and the shaft bracket 3 is rotated to make the single winding frame 5 move close to the plastic bag discharge port, and the limiting bolt 19 is rotated to pass through the fixing sleeve 18 and abut against the limiting column 17, so as to limit and fix the adjusted shaft bracket 3, and the cylinder 12 is started to drive the driving motor 10 along the fixed guide The upper surface of the rail 9 moves, so that the drive motor 10 moves to drive the spline sleeve 11 to be clamped on the outer surface of the spline shaft 7 at the corresponding position, and the drive motor 10 is started to drive the spline sleeve 11 to rotate. The input ends of the drive motor 10 and the cylinder 12 power supply are electrically connected to the output end of the external power supply, so that the hollow shaft 4 rotates as a whole to drive the winding frame 5 to rewind the plastic bag, and at the same time, the winding frame 5 that has been wound on the hollow shaft 4 at other positions is removed; compared with the prior art, this solution has the effect of facilitating the replacement of the winding frame 5 at different positions for winding operation, thereby improving the overall winding efficiency of the plastic bag after it is formed, and solving the problem of some plastic bags falling on the ground and causing pollution due to the slow replacement of the winding frame 5.
