[0002] In the prior art, PA film, PE film and PET film can be extruded through an extruder, and the PA film and PE film are adhered together to form a PAPE film.

[0003] Environmentally friendly automobile sound insulation panels include: PAPE film and PET film. Generally, environmentally friendly automobile sound insulation panels only include PAPE film. In order to achieve odor barrier, an additional layer of PET film is required. Conventional equipment cannot bond PAPE film and PET film together. Summary of the invention

[0004] The present invention provides a composite process for an environmentally friendly automobile sound insulation board material, so as to solve the problem that the PAPE film and the PET film cannot be composited together in the prior art.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] The invention discloses a composite process for an environmentally friendly automobile sound insulation board, comprising the following steps:

[0007] S1, production of PAPE film rolls;

[0008] S2, install the PAPE film roll and pull the PAPE film;

[0009] S3, the extruder extrude the front section of the PET film and install the front section of the PET film;

[0010] S4, using an end clamping device to clamp the PAPE film end and the PET film end;

[0011] S5, rotate the tensioning wheel to tighten the PAPE film;

[0012] S6, start the lifting drive mechanism, the upper rolling wheel and the lower rolling wheel clamp the end of the PAPE film and the end of the PET film, and tighten the front section of the PET film;

[0013] S7, start the rotary drive device, the extruder and the glue sprayer to produce the finished composite board.

[0014] Preferably, step S1 comprises the following steps:

[0015] S11, extruding a PA film and a PE film using an extruder;

[0016] S12, bonding the PA film and the PE film together to form a PAPE film;

[0017] S13, rolling the PAPE film into a PAPE film roll.

[0018] Preferably, step S2 comprises the following steps:

[0019] S21, installing the PAPE film roll on the mounting seat of the automotive environmental protection sound insulation board composite equipment;

[0020] S22, pulling the PAPE film out from the PAPE film roll;

[0021] S23, passing the PAPE film through the upper roller and the lower roller;

[0022] S24, passing the PAPE film through the gap between the upper rolling wheel and the lower rolling wheel;

[0023] S25, extending the PAPE film end to the end clamping device.

[0024] Preferably, step S4 includes the following steps:

[0025] S41, after adjusting the second rotation limiting mechanism, rotating the rotating cover, opening the rotating roller and the fixed roller;

[0026] S42, rotating the rotating roller so that the rotating roller cooperates with the fixed roller to clamp the end of the PAPE film and the end of the PET film.

[0027] Preferably, after executing step S6 and before executing step S7, the steps to be executed are:

[0028] S61, after adjusting the second rotation limiting mechanism, rotating the rotating cover, closing the rotating roller and the fixed roller;

[0029] S62, the position sensor detects the position of the rotating cover and determines whether the rotating cover is in the position of closing the rotating roller and the fixed roller. If so, proceed to step S7; if not, do not proceed to step S7.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] During operation, the upper rolling wheel and the lower rolling wheel both rotate toward the middle gap, and the upper rolling wheel and the lower rolling wheel both drive the composite film to move away from the extruder through friction, pulling out the PAPE film and the PET film just extruded. Since the PET film just extruded has not been completely cooled, the PET film has great tolerance and adhesion. Therefore, when the upper rolling wheel and the lower rolling wheel press the two layers of film, the PET film can be rolled onto the PAPE film, and the bonding effect is good. A glue sprayer is installed between the lower rolling wheel and the extruder, and the glue sprayer sprays glue on the PET film, thereby ensuring the adhesion strength of the two layers of film and realizing the production of double-layer composite film. In the above steps, after the PET film is extruded and formed, it is directly pulled between the upper rolling wheel and the lower rolling wheel, which not only improves the production efficiency, but also ensures that the PET film has a certain temperature, and realizes the adhesion strength after the PET film is pressed on the PAPE film. The adhesion is not only based on the adhesion of the glue, but also a certain degree of mutual melting of the surface layer of the PET film and the PAPE film, which further ensures the adhesion, makes the product quality more reliable, and improves the market competitiveness of the product.

[0032] Other advantages, objectives and features of the present invention will be embodied in part through the following description, and in part will be understood by those skilled in the art through study and practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

The rotating drive device is used to drive the upper rolling wheel 31 and the lower rolling wheel 32 to rotate, and the PAPE film and the PET film are inserted between the upper rolling wheel 31 and the lower rolling wheel 32.

[0041] The placement seat 1 includes: a base 11, an upper cover seat 12, a screw 13 and a nut 14. The base 11 and the upper cover seat 12 clamp the rotating shafts at both ends of the PAPE film roll. The base 11 is equipped with a screw 13, which passes through the upper cover seat 12. The screw 13 is threadedly connected to the nut 14, and the nut 14 cooperates with the base 11 to clamp the upper cover seat 12. By setting the base 11 and the upper cover seat 12 to be detachable, the PAPE film roll can be installed conveniently, and the PAPE film roll can be rotated after installation, so that the film can be pulled out conveniently.

[0042] The base frame 21 is supported on the ground by the support frame 25, and the roll forming device 3 is installed on the support frame 25. The installation of the base frame 21 is realized, which provides conditions for the installation of the roll forming device 3.

[0043] The bottom frame 21 is parallel to the upper frame 24, the angle between the bottom frame 21 and the horizontal direction is an acute angle, and the end of the bottom frame 21 close to the mounting seat 7 is higher than the end of the bottom frame 21 close to the extruder. The bottom frame 21 and the upper frame 24 are arranged in an inclined state, which facilitates the expansion of the PAPE film, avoids the appearance of many wrinkles due to lack of expansion, and ensures the quality of the product.

[0044] The tensioning wheel 5 is installed on the support frame 25, and the tensioning wheel 5 is located between the high end of the bottom frame 21 and the rolling device. By setting the tensioning wheel 5, the tensioning wheel 5 is installed on the support frame 25 through the mounting arm 50, and the mounting arm 50 can rotate. A screw is connected between the mounting arm 50 and the support frame 25, and the screw is used to limit the tensioning wheel 5 at the tensioning position. It is convenient to tighten the PAPE film after the PAPE film is pulled out and the end of the PAPE film is clamped.

[0045] The rotary drive device includes: a rotary motor and a gear set, the rotary motor drives the gear set to rotate, a first gear is installed on the upper rolling wheel 31, and a second gear is installed on the lower rolling wheel 32, and both the first gear and the second gear are meshed with the gear set, so as to realize driving the upper rolling wheel 31 and the lower rolling wheel 32.

[0046] The lower rolling wheel 32 can be lifted and lowered relative to the support frame 25. A lifting drive mechanism 4 is installed on the support frame 25, and the lifting drive mechanism 4 is used to drive the lower rolling wheel 32 to lift and lower. The use of the lifting drive mechanism 4 realizes the lifting and lowering of the lower rolling wheel 32. When the PAPE film and the PET film are manually inserted, the lower rolling wheel 32 is in a lower position, which is convenient for inserting the PAPE film and the PET film.

[0047] A mounting seat 7 is mounted on the support frame 25 , and an end clamping device 6 is mounted on the mounting seat 7 . The end clamping device 6 is used to clamp the ends of the PAPE film and the PET film.

[0048] The end clamping device 6 includes: a fixed roller 61 and a rotating roller 62. The fixed roller 61 and the rotating roller 62 cooperate to clamp the ends of the PAPE film and the PET film. The fixed roller 61 is fixed relative to the mounting seat 7, and the rotating roller 62 can rotate relative to the mounting seat 7. A first rotation limiting mechanism 8 is installed at the hinge of the rotating roller 62. The first rotation limiting mechanism 8 limits the rotation of the rotating roller 62.

[0049] A rotatable rotating cover 10 is installed on the side of the mounting seat 7 away from the lower rolling wheel 32, and the rotating cover 10 is used to cover the fixed roller 61 and the rotating roller 62. It is avoided that the hand is pinched when the rotating roller 62 is automatically deflected.

[0050] A second rotation limiting mechanism 9 is installed at the hinge between the rotating cover 10 and the mounting seat 7 , and the second rotation limiting mechanism 9 is used to limit the rotation of the rotating cover 10 .

[0051] The first rotation limiting mechanism 8 includes: a rotation limiting arm 82, a connecting arm 83 and a first spring 84. The rotating roller 62 is installed on a rotating arm that can rotate relative to the mounting seat 7. The rotation limiting arm 82 is used to be inserted into the rotation limiting hole opened in the rotating arm. The rotation limiting arm 82 is connected to the connecting arm 83. The connecting arm 83 and the rotation limiting arm 82 can move relative to the mounting arm 50 in a direction parallel to the center line around which the rotating arm rotates. The connecting arm 83 is connected to the inner wall of the mounting seat 7 through the first spring 84. Under the elastic force of the first spring 84, the rotation limiting arm 82 can be kept inserted into the rotation limiting hole. The rotating roller 62 can be inserted into the rotation limiting hole only when it is located at the station for clamping the ends of the PAPE film and the PET film. The side surface of the rotating arm is recessed to form an arc groove, and the arc groove forms a guide inner wall. The guide inner wall is used to guide the rotation limiting arm 82 into the rotation limiting hole.

[0052] The connecting arm 83 is connected to a ball 85, and an inclined arc surface 72 is formed on the side of the rotating cover 10. The inclined arc surface 72 is tangent to the ball 85. The inclined arc surface 72 is used to squeeze the ball 85 to disengage the rotation limiting arm 82 from the rotation limiting hole. When the rotating cover 10 is in a position covering the fixed roller 61 and the rotating roller 62, the inclined arc surface 72 squeezes the ball 85 to disengage the rotation limiting arm 82 from the rotation limiting hole.

[0053] The second rotation limiting mechanism 9 includes: a clamping arm 91, a gear ring 92, a toggle block 93 and a second spring 94. The rotating cover 10 is hinged to a hinge shaft, the hinge shaft is fixed to the mounting seat 7, and a gear ring 92 is fixed on the hinge shaft. The gear ring 92 can mesh with the clamping arm 91. The clamping arm 91 is installed on the rotating cover 10. The clamping arm 91 can move relative to the rotating cover 10 in the radial direction of the hinge shaft. The clamping arm 91 is connected to a toggle block 93 extending out of the rotating cover 10. The toggle block 93 is fixed to the inner wall of the rotating cover 10 by the second spring 94. A sliding groove for the toggle block 93 to move is provided on the rotating cover 10. Under the elastic force of the second spring 94, the clamping arm 91 can be kept engaged with the gear ring 92.

[0054] This embodiment also discloses a composite process of an environmentally friendly sound insulation board for automobiles, comprising the following steps:

[0055] S1, production of PAPE film rolls;

[0056] S2, install the PAPE film roll and pull the PAPE film;

[0057] S3, the extruder extrude the front section of the PET film and install the front section of the PET film;

[0058] S4, using the end clamping device 6 to clamp the PAPE film end and the PET film end;

[0059] S5, rotating the tensioning wheel 5 to tighten the PAPE film;

[0060] S6, start the lifting drive mechanism 4, the upper rolling wheel 31 and the lower rolling wheel 32 clamp the PAPE film end and the PET film end, and tighten the front section of the PET film;

[0061] S7, start the rotary drive device, the extruder and the glue sprayer to produce the finished composite board.

[0062] Step S1 includes the following steps: S11, using an extruder to extrude a PA film and a PE film; S12, bonding the PA film and the PE film together to form a PAPE film; S13, rolling the PAPE film into a PAPE film roll.

[0063] Step S2 includes the following steps: S21, installing the PAPE film roll on the mounting seat 7 of the automotive environmental protection sound insulation board composite equipment; S22, pulling the PAPE film out from the PAPE film roll; S23, passing the PAPE film through the upper roller 23 and the lower roller 22; S24, passing the PAPE film through the gap between the upper rolling wheel 31 and the lower rolling wheel 32; S25, extending the end of the PAPE film to the end clamping device 6.

[0064] Step S4 includes the following steps: S41, after adjusting the second rotation limiting mechanism 9, rotate the rotating cover 10 to open the rotating roller 62 and the fixed roller 61; S42, rotate the rotating roller 62 so that the rotating roller 62 cooperates with the fixed roller 61 to clamp the PAPE film end and the PET film end.

[0065] After executing step S6 and before executing step S7, the steps that need to be executed are: S61, after adjusting the second rotation limiting mechanism 9, rotate the rotating cover 10 to close the rotating roller 62 and the fixed roller 61; S62, the position sensor detects the position of the rotating cover 10 to determine whether the rotating cover 10 is in the state of closing the rotating roller 62 and the fixed roller 61. If so, proceed to step S7; if not, do not proceed to step S7.

[0066] After executing step S6, the upper rolling wheel 31 and the lower rolling wheel 32 have already compressed and tightened the PAPE film and the PET film, and the end clamping device 6 is used to pre-clamp the ends of the PAPE film and the PET film, avoiding the hand from being stretched between the upper rolling wheel 31 and the lower rolling wheel 32 to keep the PAPE film and the PET film tight, avoiding the sudden driving of the lifting drive mechanism 4 and causing the hand to be pinched, and realizing the state where the end clamping device 6 replaces the manual clamping, thereby improving safety protection. The rotating cover 10 is rotated so that the fixed roller 61 and the rotating roller 62 are covered. While the rotating cover 10 covers the fixed roller 61 and the rotating roller 62, it also blocks one side of the upper rolling wheel 31 and the lower rolling wheel 32, further improving safety protection. At the same time, when the rotating cover 10 is rotated to the position covering the fixed roller 61 and the rotating roller 62, the first rotation limiting mechanism 8 can release the rotating arm, and the rotating arm can be tilted. Since there is a distance between the rotating cover 10 and the upper rolling wheel 31 and the lower rolling wheel 32, the finished product section can be pulled out, which is convenient for subsequent convolution and other operations.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
