[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] The embodiments of this utility model will be described below based on its overall structure.

[0022] Please see Figure 1-4A web-aligning device for LDPE film production includes a mounting frame 1. A first magnetic block 2 is adhered to the inner wall of the mounting frame 1, and the inner wall of the mounting frame 1 is in close contact with the outer wall of the first magnetic block 2. The inner wall of the mounting frame 1 has a slotted design. A second magnetic block 3 is adhered to the outer wall of the first magnetic block 2, and a first guide frame 4 is adhered to the outer wall of the second magnetic block 3. The outer wall of the second magnetic block 3 is in close contact with the outer wall of the first guide frame 4, and the length of the outer wall of the second magnetic block 3 is less than the length of the outer wall of the first guide frame 4. By setting the first magnetic block 2 to achieve a tight fit with the second magnetic block 3, the arrangement of the first magnetic block 2 and the second magnetic block 3 facilitates the quick and easy installation of the first guide frame 4 during device use, increasing the usability of the device.

[0023] Please see Figure 1-4 A web-aligning device for LDPE film production includes an adjusting rod 5 mounted on the inner wall of a mounting frame 1. The adjusting rod 5 is movably connected to the mounting frame 1, and the outer wall of the adjusting rod 5 is threaded. A spring 6 abuts against the outer wall of the adjusting rod 5, and one end of the spring 6 abuts against a web-aligning block 7. The adjusting rod 5 and the web-aligning block 7 are threaded together, and the inner wall of the web-aligning block 7 is threaded. A third magnetic block 8 is adhered to the inner wall of the web-aligning block 7, and a fourth magnetic block 9 is attached to the outer wall of the third magnetic block 8. A second guide frame 10 is adhered to the outer wall of the fourth magnetic block 9, and the web-aligning block 7 and the second guide frame 10 are engaged. The inner wall of the web-aligning block 7 has a slotted design. By setting the web-aligning block 7, the second guide frame 10 is engaged and fixed.
