[0002] Film-coated paper refers to a kind of paper product obtained by coating plastic films such as BOPP and PET on the paper surface and undergoing special treatment. Due to its characteristics such as water resistance, moisture resistance, and oil resistance, film-coated paper is widely used in the fields of packaging printing, trademarks, calendars, photos, etc. In the process of use, heating and bonding are common operation methods. This device is a film-coated paper heating mechanism for the production of gum-free paper straws.

[0003] When the film-coated paper heating mechanism is in use, the film-coated paper is conveyed into the heating box with the assistance of a conveying device for heating treatment.

[0024] See also Figures 1-5 , the utility model provides an embodiment: a coated paper heating mechanism for the production of non-glue paper straws, comprising a heating box 1, an auxiliary box 6 and an air inlet pipe 7. An extension component is provided on one side of the heating box 1, and the extension component includes a fixed platform 2, a fixing bolt 3, a receiving groove 4, an extension box 5 and an auxiliary box 6. A fixed platform 2 is fixed on one side of the top of the heating box 1. Two groups of fixed platforms 2 are fixed on one side of the top of the heating box 1. The two groups of fixed platforms 2 are distributed in parallel. A fixing bolt 3 is provided inside the fixed platform 2. A receiving groove 4 is provided on one side of the heating box 1. The bottom end of the fixing bolt 3 extends to the inside of the receiving groove 4. The inside of the receiving groove 4 is provided with an extension box 5. A auxiliary box 6 is installed on one side of the extension box 5. The air inlet pipe 7 is installed on the top of the heating box 1 and the auxiliary box 6.

[0025] Specifically, if Figure 1 、 Figure 2 and Figure 3 As shown, when in use, after the fixing bolt 3 is loosened, the expansion box 5 can be moved along the storage slot 4 to the side end of the heating box 1. With the help of the expansion box 5 extending outward, the heating box 1, the expansion box 5 and the auxiliary box 6 cooperate to assist in expanding the overall internal space;

[0026] At the top of both the heating box 1 and the auxiliary box 6, an adjustment table 8 is fixedly installed. On one side of the adjustment table 8, a chute 9 is provided. Inside the adjustment table 8, a baffle 10 is provided. On one side of the baffle 10, a connection hole 11 is provided. Inside the chute 9, a connection bolt 12 is provided. One side of the connection bolt 12 extends into the inside of the connection hole 11. Inside the connection hole 11, internal threads are provided. On the surface of the connection bolt 12, external threads are provided. At the bottom end of the baffle 10, a bottom groove 13 is provided. Inside the bottom groove 13, an upper roller 14 is movably installed;

[0027] Specifically, as Figure 1 , Figure 2 and Figure 4 shown, during use, the upper roller 14 is located above the lower roller 16. The connection bolt 12 is connected to the baffle 10 inside the adjustment table 8. After the connection bolt 12 is screwed loose, the connection bolt 12 can assist in driving the baffle 10 to move downward. In this way, the distance between the upper roller 14 and the lower roller 16 can be reduced, and the size of the opening here can be reduced;

[0028] At the bottom end of both the heating box 1 and the auxiliary box 6, a feeding table 15 is fixedly installed. Inside the feeding table 15, a lower roller 16 is movably installed.

[0029] Specifically, as Figure 1 , Figure 2 and Figure 5 shown, during use, after the locking bolt 22 is screwed loose, the limiting plate 17 can slide along the guiding rod 20 with the assistance of the guiding platform 18. In this way, the two groups of limiting plates 17 can be adjusted to both sides of the coating paper. With the help of the two groups of limiting plates 17, the conveying position of the coating paper is limited.

[0030] Working principle: When in use, the coated paper enters from one side end of the heating box 1, passes through the auxiliary box 6 on the other side, and the conveying equipment is used to assist in the conveying operation of the coated paper. As needed, the fixing bolt 3 on the top of the heating box 1 can be loosened, and the sliding part of the extension box 5 is moved to the outside to assist in adjusting the internal space. After the adjustment is completed, the fixing bolt 3 is tightened for fixation. Then, the connecting bolt 12 can be loosened, and the baffle 10 is slid downward by means of the connecting bolt 12 to drive the upper roller 14 above the lower roller 16. The distance between them allows the coated paper to move. After reducing the size of the side opening, the connecting bolt 12 is tightened for fixation. Finally, after the locking bolt 22 is loosened, the two sets of limiting plates 17 can be slid to both ends of the coated paper. With the assistance of the two sets of limiting plates 17, the moving position of the coated paper can be limited. Then, the air inlet pipe 7 can be externally connected to the equipment to introduce hot air, and the hot air is used to heat the coated paper conveyed inside.
