[0042] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0043] like Figures 1-6 As shown, a coating machine for processing paint protective film includes a housing 1, a fixed frame 2, an unwinding roller 3, a sleeve 4, a drive unit, a take-up roller 5, a storage box 6, an adhesive coating roller 7, a drying mechanism, a recycling mechanism, and a connecting mechanism. The housing 1 has an inlet 11 and an outlet 12 on both sides. The fixed frame 2 is symmetrically arranged on both sides of the housing. The unwinding roller 3 is rotatably mounted on the fixed frame, and protective film material is wound on it. The sleeve 4 is rotatably mounted on the fixed frame. The drive unit uses a conventional motor, and its output shaft is connected to the sleeve. The storage box 6 is fixed inside the housing and contains adhesive. The adhesive coating roller 7 is rotatably mounted inside the storage box and is driven to rotate by the motor. The protective film material enters the housing from the inlet, then winds onto the adhesive coating roller, and then winds onto the take-up roller through the outlet. The take-up roller 5 is detachably connected to the sleeve via a connecting mechanism.

[0044] Specifically, the recycling mechanism includes a connecting rod 71, a mounting plate 72, a leveling roller 73, a scraper 74, a fixing seat 75, a screw 76, a guide rod 77, and a connecting plate 78. A sliding groove 13 is provided on the side wall of the box, and the connecting rod 71 is located within the sliding groove, allowing it to slide up and down relative to the groove. The mounting plate is fixed to the end of the connecting rod. The leveling roller 73 is rotatably connected to the mounting plate. The scraper 74 is fixed to the mounting plate. The fixing seat 75 is fixed to the outer wall of the box. The screw 76 is rotatably connected to the fixing seat. One end of the guide rod 77 is fixed to the fixed base; the connecting plate 78 is symmetrically fixed on both sides of the connecting rod. The connecting plate is provided with guide holes that cooperate with the guide rod and threaded holes that cooperate with the screw. The glue can be spread evenly by the leveling roller, and the excess glue can be scraped off by the scraper and then flowed back into the storage box by the scraper, thereby ensuring that the glue is uniform and recovering the excess glue. The mounting plate can be moved up and down by rotating the screw, thereby adjusting the distance between the leveling roller, the scraper and the protective film.

[0045] Specifically, the connecting mechanism includes a rotating shaft 81, a push plate 82, a limiting protrusion 83, a locking rod 84, a baffle 85, a handle 86, a first elastic element 87, and a limiting assembly. The rotating shaft 81 is rotatably disposed within the sleeve; the push plate 82 is uniformly fixed on the rotating shaft and has an arc-shaped curved surface; the limiting protrusion 83 is fixed on the outer wall of the sleeve, and the take-up roller has a limiting groove for the limiting protrusion to be inserted; the locking rod 84 passes through the sleeve and can slide relative to the outer wall of the sleeve; the baffle 85 is fixed on the outer wall of the locking rod; the handle 86 is fixed on the end of the rotating shaft; the first elastic element 87 is a metal spring, which is sleeved on the locking rod, and one end of it... One end is fixed to the baffle, and the other end is fixed to the inner wall of the sleeve. The take-up roller has a locking hole that cooperates with the locking rod. When installing the take-up roller, align the limiting protrusion with the limiting groove, then put the take-up roller on the sleeve. Then, turn the shaft by the handle, and push the locking rod upward by the push plate, thereby inserting the locking rod into the locking hole, thus completing the fixation of the take-up roller and the sleeve. The installation is convenient. After the collecting roller has finished collecting, turn the shaft in the opposite direction. The first elastic element will pull the locking rod out of the locking hole, and then the take-up roller can be taken out. Then, repeat the installation steps to install the new take-up roller. Replacing the take-up roller is very convenient.

[0046] As a preferred embodiment, the limiting assembly includes a connecting sleeve 881, a mounting hole 882, a second elastic element 883, a push rod 884, and a first ball bearing 885. The connecting sleeve 881 is fixed to the end of the sleeve and has a through hole for the rotating shaft to pass through and rotate. The mounting hole 882 is opened on the rotating shaft. The second elastic element 883 is a metal spring, one end of which is fixed in the mounting hole. One end of the push rod 884 is fixed to the end of the second elastic element and can slide relative to the inner wall of the mounting hole. The first ball bearing 885 is rotatably connected to the end of the push rod. The inner wall of the through hole has a groove that mates with the first ball bearing. When the locking rod is inserted into the locking hole, the first ball bearing is aligned with the groove, and the second elastic element pushes the first ball bearing into the groove, thereby limiting the rotating shaft and preventing the rotating shaft from rotating during the winding process.

[0047] Specifically, the drying mechanism includes a motor 91, a fan blade 92, and a heating wire 93. The motor 91 is a conventional servo motor, which is fixed inside the housing; the fan blade 92 is fixed on the output shaft of the motor; and the heating wire 93 is fixed above the fan blade. When the motor and heating wire are started, hot air is blown onto the glue to dry it.

[0048] In other embodiments, a second ball bearing 841 is rotatably provided at the end of the locking lever 84 to facilitate the push plate to move the locking lever.

[0049] In other embodiments, the inner wall of the box is provided with a partition 94, and the partition is provided with a material inlet 941 to ensure the drying effect and prevent hot air from contacting the adhesive in the storage box; a first guide roller 95 is provided on both sides of the material inlet; and a second guide roller 96 is provided at the discharge port.

[0050] In other embodiments, a guide plate 741 is fixed to the bottom of the scraper 74, and the guide plate is curved in an arc shape.

[0051] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
