Description

Technical Field

[0001] This utility model relates to the field of embossing film technology, specifically to a heating device for PET embossing film. Background Technology

[0002] Embossing is a process that uses a die to plastically deform a PET film under certain temperature and pressure. When processing PET embossed film, it needs to be placed inside a heating device to be heated to a specified temperature before embossing.

[0003] The patent, titled "A Heating Device for PET Embossing Film" and with publication number CN214188444U, describes a method to achieve compensated heating of the first heating rollers by setting up two hollow inner-liner-type first heating rollers and a compensation oil tank. The compensation oil tank delivers heat transfer oil to the inside of the first heating rollers through an oil supply pipe and a heat transfer oil rotary joint. The heat transfer oil is then heated by twelve heating tubes inside the first heating rollers, improving thermal efficiency. However, in this patent, the PET embossing film moves on the guide rollers and is heated by the heating rollers. During the heating process, the device cannot flatten the embossing film, fails to make sufficient contact with the heating rollers, and wrinkles easily form on the embossing film, affecting the uniformity of the pattern. Utility Model Content

[0004] The purpose of this invention is to provide a PET embossed film heating device to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A PET embossed film heating device includes a housing with an inlet and an outlet on both sides. A heating plate is fixedly installed on the bottom inside the housing. An adaptive component is also installed inside the housing. The adaptive component includes a pressure roller with both ends rotatably connected to a connecting frame. The connecting frame is slidably connected to a support frame, and an elastic part is provided between the connecting frame and the support frame. The support frame is driven by a driving part installed inside the housing, and the driving part drives the pressure roller to perform reciprocating linear motion.

[0007] Furthermore, the drive unit includes a first rotating shaft and a second rotating shaft respectively rotatably disposed inside the housing. A motor is fixedly disposed on the housing. One end of the first rotating shaft passes through the housing and is fixedly connected to the output shaft of the motor. The first rotating shaft and the second rotating shaft are connected by belt drive.

[0008] Furthermore, a first pulley is fixedly connected to each side of the first rotating shaft, and a second pulley corresponding to the first pulley is fixedly connected to each side of the second rotating shaft. The first pulley and the corresponding second pulley are connected by a synchronous belt, and the two synchronous belts are fixedly connected to each side of the support frame.

[0009] Furthermore, the support frame includes a frame body disposed inside the box, and pressure plates are provided on both sides of the frame body, the pressure plates being threadedly connected to the frame body.

[0010] Furthermore, the elastic part is a compression spring, which is disposed between the support frame and the connecting frame.

[0011] Furthermore, the heating plate is an electric heating plate.

[0012] In the above technical solution, the PET embossed film heating device provided by this utility model has the following beneficial effects:

[0013] With the adaptive components, the film enters the box from the feed port, is located between the pressure roller and the heating plate, and is discharged from the discharge port after heating. The pressure roller in the box can press the film onto the heating plate for heating, and under the drive of the drive unit, the pressure roller makes a reciprocating linear motion, that is, the heating plate rolls back and forth, thereby eliminating wrinkles and improving the quality of embossing.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure.

[0028] Please see Figure 1-5 A PET embossing film heating device includes a housing 1, with an inlet 11 and an outlet 12 on both sides of the housing 1. A heating plate 2 is fixedly installed on the bottom inside the housing 1. An adaptive component 3 is also installed inside the housing 1. The adaptive component 3 includes a pressure roller 31, both ends of which are rotatably connected to a connecting frame 32. The connecting frame 32 is slidably connected to a support frame 33, and an elastic part 34 is provided between the connecting frame 32 and the support frame 33. The support frame 33 is driven by a driving part installed inside the housing 1, and the driving part drives the pressure roller 31 to perform reciprocating linear motion. A door with an observation window is provided on one side of the housing 1.

[0029] The elastic part 34 keeps the pressure roller 31 pressed against the heating plate 2, see attached drawing. Figure 5 The support frame 33 slides and limits the connecting frame 32, that is, the connecting frame 32 cannot slide off the support frame 33.

[0030] The membrane can be kept taut by using traction mechanisms (such as unwinding and rewinding mechanisms) on both sides. This is a common technique used by those skilled in the art and will not be described in detail here.

[0031] Furthermore, the drive unit includes a first rotating shaft 41 and a second rotating shaft 42 respectively rotatably disposed within the housing 1. A motor 43 is fixedly disposed on the housing 1. One end of the first rotating shaft 41 passes through the housing 1 and is fixedly connected to the output shaft of the motor 43. The first rotating shaft 41 and the second rotating shaft 42 are connected by belt drive. A first pulley 44 is fixedly connected to both sides of the first rotating shaft 41, and a second pulley 45 corresponding to the first pulley 44 is fixedly connected to both sides of the second rotating shaft 42. The first pulley 44 and the corresponding second pulley 45 are connected by a synchronous belt 46, and the two synchronous belts 46 are fixedly connected to both sides of the support frame 33.

[0032] Motor 43 drives the first rotating shaft 41 to rotate, which in turn drives the first pulley 44 to rotate. The rotation of the first pulley 44, via synchronous belt 46, drives the second pulley 45 to rotate. The movement of synchronous belt 46 between the first pulley 44 and the second pulley 45 moves the support frame 33, which in turn moves the connecting frame 32, which in turn moves the pressure roller 31. The motor 43 can rotate in both forward and reverse directions, causing the pressure roller 31 to reciprocate.

[0033] Furthermore, the support frame 33 includes a frame 331 disposed inside the housing 1, and pressure plates 332 are disposed on both sides of the frame 331, and the pressure plates 332 are threadedly connected to the frame 331.

[0034] The timing belt 46 is located between the frame 331 and the pressure plate 332. The movement of the timing belt 46 drives the frame 331 to move as a whole. It is understood that the frame 331 is also slidably connected to the inner wall of the box 1, thereby ensuring the stability of the frame 331 when it moves.

[0035] Furthermore, the elastic part 34 is a compression spring, which is disposed between the support frame 33 and the connecting frame 32.

[0036] Furthermore, the heating plate 2 is an electric heating plate 2.

[0037] Working principle: The motor 43 drives the first rotating shaft 41 to rotate, the first rotating shaft 41 drives the first pulley 44 to rotate, the first pulley 44 drives the second pulley 45 to rotate through the synchronous belt 46, the synchronous belt 46 moves between the first pulley 44 and the second pulley 45 to move the support frame 33, the support frame 33 moves to move the connecting frame 32, the connecting frame 32 moves to move the pressure roller 31 to reciprocate on the heating plate 2, which can eliminate wrinkles and make the film adhere tightly to the heating plate 2 for heating.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
