[0028] Example

[0029] As 1 to Figure 3As shown in the figure, a paper tube bracket for PE winding film production proposed by the present utility model includes a support plate 1 for support. A guiding rail 2 for guiding is fixedly arranged on the upper surface of the support plate 1, and the guiding rail 2 is arranged in a "T" - shaped structure. Limit blocks 12 are respectively clamped at both ends of the guiding rail 2, which can limit the first clamping block 3 and the second clamping block 4 to prevent displacement and detachment from the guiding rail 2. A scale mark 13 is arranged on the upper surface of the guiding rail 2, which is convenient for obtaining the adjusted distance between the first clamping block 3 and the second clamping block 4.

[0030] Further, a group of first clamping blocks 3 slidably sleeved on the guiding rail 2, and a second clamping block 4 is movably sleeved at one end of the first clamping block 3. The first clamping block 3 and the second clamping block 4 are arranged in a "C" - shaped structure, which can stably clamp on the outer wall of the guiding rail 2. An adjusting bolt 5 is rotatably sleeved on the second clamping block 4, and one end of the adjusting bolt 5 is threadedly sleeved with the first clamping block 3, which can adjust the tightness of the clamping between the first clamping block 3 and the second clamping block 4 and the guiding rail 2, so as to facilitate adjusting the distance between the first clamping block 3 and the second clamping block 4, and improve the applicable range for paper tube brackets of different lengths.

[0031] As Figure 1 、 Figure 3 and Figure 4 shown, a clamping component 6 for the PE winding film paper tube bracket is fixedly arranged on the upper surface of the first clamping block 3. The clamping component 6 includes a clamping ring 61 arranged directly above the first clamping block 3, and the clamping ring 61 is arranged in an arc - shaped structure, which can stably clamp the paper tube. First roller shafts 62 are respectively rotatably arranged at both ends of the clamping ring 61, which is convenient for the paper tube to be inserted into the inside of the clamping ring 61 and can prevent the paper tube from being damaged when inserted into the inside of the clamping ring 61. A groove 63 is formed on the inner ring surface of the clamping ring 61, and a plurality of second roller shafts 64 are rotatably arranged inside the groove 63 to ensure that the paper tube rolls stably inside the clamping ring61.

[0032] Furthermore, a base 7 is arranged on the bottom surface of the clamping ring 61, and the upper surface of the base 7 is arranged in an arc - shaped structure, which can closely adhere to the bottom surface of the clamping ring 61 to provide stable support for the clamping ring 61. The bottom surface of the base 7 is fixedly connected to the first clamping block 3. Through - holes 8 are formed on the side surface of the base 7, and at least two through - holes 8 are provided. A supporting bottom frame 9 is movably sleeved on the base 7. Both ends of the supporting bottom frame 9 are fixedly connected to the bottom surface of the clamping ring 61. Guide through - grooves 10 are respectively formed on both sides of the supporting bottom frame 9. A limiting bolt 11 is arranged through the through - hole 8 and the guide through - groove 10, which can stably limit the supporting bottom frame 9 and is convenient for adjusting the angle of the clamping of the clamping component 6 and for taking and placing.

[0033] The working principle of this embodiment is as follows: First, according to the length of the PE stretch film tube, rotate the adjusting bolt 5 to make the second locking block 4 move horizontally inside the first locking block 3. Then, push the first locking block 3 and the second locking block to a suitable position on the outer wall of the guide rail 2. Precise positioning can be achieved through the scale mark 13. After adjustment, rotate the adjusting bolt 5 in the opposite direction. Since one end of the adjusting bolt 5 is threadedly connected to the first locking block 3 and the other end is rotatably connected to the second locking block 4, the second locking block 4 will move relative to the first locking block 3 as the adjusting bolt 5 rotates, thereby tightening the connection between the first locking block 3 and the guide rail 2 and ensuring that the locking block position is fixed.

[0034] The PE stretch film paper tube is pressed and inserted into the retaining ring 61 of the retaining ring assembly 6. The multiple second rollers 64 in the groove 63 on the inner annular surface of the retaining ring 61 can reduce the friction between the paper tube and the retaining ring 61, making it easier for the paper tube to rotate. At the same time, the first rollers 62 at both ends of the retaining ring 61 can also help to place the paper tube stably and limit the paper tube to prevent it from moving out of the retaining ring 61 during rotation.

[0035] If it is necessary to adjust the angle of the retaining ring 61, the limiting bolt 11 can be loosened to push the supporting base frame 9 and drive the retaining assembly 6 to rotate. The supporting base frame 9 ensures the stability of the retaining assembly's rotation through the guide groove 10 and the limiting bolt 11. During the rotation of the retaining assembly 6, the bottom of the retaining ring 61 is in close contact with the base 7, further ensuring the stability of the retaining assembly 6's rotation. After the supporting base frame 9 has rotated to the appropriate angle, the limiting bolt 11 is rotated in the opposite direction to fix it.

[0036] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
