Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5A roll for easy installation in film rolling includes a roll 1 and a connecting shaft 2. Both ends of the roll 1 are provided with insert blocks 11. The insert blocks 11 fit into the locking grooves 4 opened on the upper wall of the connecting shaft 2. The upper part of the insert blocks 11 is provided with fastening bolts 12. The bottom end of the fastening bolts 12 extends into the interior of the connecting shaft 2 and presses against a wedge block 22. One end of the wedge block 22 extends out of the connecting shaft 2 and is inserted into a slot 13 opened on the outside of the roll 1.

[0024] A mating hole 111 is provided on one side of the middle part of the insert block 11. A fastening bolt 12 is inserted into the mating hole 111 for limiting. The upper part of the fastening bolt 12 is a smooth section and the bottom part is a threaded section.

[0025] The smooth section is inserted into the mating hole 111, and the threaded section passes directly through the mating hole 111.

[0026] A slot 13 is provided below the insert block 11.

[0027] The connecting shaft 2 has an internal mounting groove 3, and a threaded hole is provided between the mounting groove 3 and the snap-fit ​​groove 4. The threaded hole is used to mate with the threaded section of the fastening bolt 12.

[0028] A wedge block 22 is slidably installed in the mounting groove 3. The upper side of the wedge block 22 has an inclined surface, and the middle part of the inclined surface is pressed and contacted with the bottom end of the fastening bolt 12. The other side of the wedge block 22 extends out of the outer wall of the connecting shaft 2.

[0029] The mounting groove 3 and the wedge block 22 are connected by a spring 24. When the wedge block 22 moves, the spring 24 deforms.

[0030] Extension rods 25 are installed on both sides of the wedge block 22. The extension block 25 extends out into the limiting groove 21 opened on the outside of the connecting shaft 2, and the extension rods 25 are limited and installed in the limiting groove 21.

[0031] Limiting grooves 21 are provided on both outer sides of the connecting shaft 2.

[0032] A pin 112 is installed on one side of the bottom of the insert block 11. When the insert block 11 is connected to the snap-fit ​​groove 4, the insert block 11 is inserted into the blind groove opened on the inner wall of the snap-fit ​​groove 4.

[0033] A guide groove 23 is provided in the middle of the wedge block 22. The guide groove 23 fits into the bottom end of the fastening bolt 12 to ensure the relative sliding stability of the wedge block 22.
