Description

Technical Field

[0001] The invention belongs to the technical field of composite film coating, in particular to a coating device for a thermal insulation film. Background Art

[0002] Thermal insulation film is a thin film that is attached to the glass of houses or cars. It can absorb and reflect infrared rays from sunlight, thereby lowering the temperature inside the room or car. It can also reduce the glare caused by strong sunlight. In the process of making thermal insulation film, according to different process requirements, the thermal insulation film needs to be coated multiple times to achieve the required thermal insulation coefficient value.

[0003] Among the existing coating technologies, the most commonly used one is the roller coating method, which generally involves spraying the coating liquid on a roller and coating the thermal insulation film with the roller. However, this coating method generally causes a large amount of coating liquid to fall onto the outside of the roller, and each time the coating liquid is sprayed onto the roller, this portion of the thermal insulation film will be over-sprayed, which results in material waste and reduces the quality of the thermal insulation film. For this reason, we provide a coating device for thermal insulation films. Summary of the invention

[0004] In order to solve the problems raised in the above-mentioned background technology, the present invention provides a coating device for thermal insulation film, which solves the problem that a large amount of coating liquid will fall on the outside of the roller in the prior art, and each time the coating liquid is sprayed onto the roller, the thermal insulation film in that part will be over-coated, thereby causing material waste.

[0005] To achieve the above object, the present invention provides the following technical solution: a coating device for a thermal insulation film, comprising a bracket, a thermal insulation film, a first support plate and a second support plate, and further comprising:

[0006] A motor fixedly mounted on the outer side of the support plate, and a return box fixedly mounted on the outer side of the support plate;

[0011] A parallel flow pipe is commonly installed on the outer periphery of the two diverter boxes, and the end of the parallel flow pipe is used for threaded connection with the discharge port of the coating material conveying equipment;

[0012] Two reflux components fixed on the bracket;

[0013] The reflux assembly includes a reflux box fixed inside the bracket, and the reflux box is used to receive excess coating material.

[0014] Preferably, the reflux assembly further comprises a chain transmission-connected to both sides of the roller, a threaded conveying rod is installed on the internal bearing of the reflux box, and the roller is transmission-connected to the threaded conveying rod via the chain.

[0015] Preferably, the rolling assembly also includes a reciprocating threaded rod fixedly mounted on the second support plate and located inside the roller, the outer peripheral threaded sleeve of the reciprocating threaded rod is provided with a limit frame, the limit frame is hingedly connected to two extrusion plates on one side close to the motor, and the cover plate two is movably clamped on one side of the roller.

[0016] Preferably, the reflux assembly further comprises a feed pipe connected to the interior of the reflux box, the feed pipe is connected to the interior of the roller through cover plate 2, and a scraper is fixedly mounted on the side of the reflux box.

[0017] Preferably, the rolling assembly further comprises a cover plate 1 clamped on the side of the roller, the interior of the roller is connected to a discharge pipe via the cover plate 1, and the end of the discharge pipe is connected to the interior of the reflux box.

[0018] Preferably, the diversion assembly also includes a cleaning tube fixed on the diversion box, and both ends of the cleaning tube are connected to the interior of the roller through cover plate 2 and cover plate 1 respectively. First slots are equidistantly opened on the cleaning tube, and the opening of the first slot faces the side of the thermal insulation film.

[0019] Preferably, a partition is provided on one side of the limiting frame close to the second cover plate, and the two extrusion plates are hinged to the other side of the limiting frame, and the extrusion plates are made of rubber.

[0020] Preferably, the thermal insulation film is located between two baffles, the baffles are made of rubber, and the thermal insulation film is clamped by two rollers.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The present invention cooperates with structures such as a rolling assembly and a diversion assembly. The roller drives the protruding ends of the two camshafts to continuously push one end of the trigger plate up, and conversely, the other end drives the baffle to move outward. The coating material inside the diversion box flows downward to the surface of the roller through the second slot, and is rolled onto the surface of the bracket by the roller. When the protruding end of the camshaft no longer contacts the trigger plate, the tension spring pulls the baffle to fit the side of the diversion box through the trigger plate, and the coating material inside the diversion box does not flow out. After the roller rotates one circle, the coating material contaminated thereon is evenly coated on the surface of the thermal insulation film, and excess coating material on the roller will flow to the inside of the reflux box, thereby further reducing the waste of coating material and preventing the thermal insulation film from being coated with too much liquid.

[0023] The present invention cooperates with structures such as a rolling assembly and a reflux assembly. During the rotation of the roller, the limit frame moves axially according to the thread groove on the reciprocating threaded rod. When the limit frame moves toward the motor side, the extrusion plate clings to the side of the limit frame, thereby extracting the coating material inside the reflux box through the feed pipe. The limit frame also cooperates with the extrusion plate to extrude the material, allowing it to enter the interior of the reflux box through the discharge pipe and then wait for the next use, thereby further avoiding material waste.

[0024] The present invention arranges the cooperation of structures such as a rolling assembly and a diversion assembly. During the process of the limit frame and the extrusion plate extruding the material into the reflux box, the air inside the roller will also be squeezed into the inside of the cleaning tube, and finally discharged to the side of the thermal insulation film through the first slot, thereby ensuring that the surface of the thermal insulation film is completely dry and free of dust after the coating process at the previous workstation, thereby improving the quality of the thermal insulation film after coating.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] like Figures 1 to 8 As shown, the present invention provides a coating device for a thermal insulation film, comprising a bracket 1, a thermal insulation film 2, a support plate 1 9 and a support plate 2 10, and further comprising:

[0036] A motor 4 fixedly mounted on the outside of a support plate 9, and a return box 3 fixedly mounted on the outside of a support plate 9;

[0037] The bearings are mounted on two rolling assemblies 6 on the inner side of the support plate 9;

[0038] The rolling assembly 6 includes a roller 61 with a bearing mounted on the inner side of the support plate 9, one side of the roller 61 is drivingly connected to the output shaft of the motor 4, and the other side of the roller 61 is drivingly connected to a gear 62, the two gears 62 are meshed, and a cam shaft 63 is fixedly mounted on each side of the roller 61;

[0039] Two flow dividing components 5 fixedly mounted on the bracket 1;

[0040] The flow dividing assembly 5 comprises a flow dividing box 51 fixedly mounted on the bracket 1, a baffle 56 is hingedly connected to one side of the flow dividing box 51 close to the heat insulation film 2, a plurality of second notches 57 are evenly spaced on one side of the flow dividing box 51, a trigger plate 55 is hingedly connected to each of the two sides of the flow dividing box 51, the middle of each trigger plate 55 is elastically hinged to the flow dividing box 51 through a tension spring 54, and the two sides of the baffle 56 are slidably mounted on the sides of the two trigger plates 55;

[0041] A parallel flow pipe 8 is commonly installed on the outer periphery of the two flow dividing boxes 51, and the end of the parallel flow pipe 8 is used for threaded connection with the discharge port of the coating material conveying device;

[0042] Two reflux components 7 fixedly mounted on the bracket 1;

[0043] The reflux assembly 7 includes a reflux box 71 fixed inside the bracket 1 , and the reflux box 71 is used to receive excess coating material.

[0044] The thermal insulation film 2 is located between two baffles 56 . The baffles 56 are made of rubber. The thermal insulation film 2 is clamped by two rollers 61 .

[0045] The above solution is adopted: when the bracket 1 is in the working state, the motor 4 is started, so that the output shaft of the motor 4 drives the roller 61 to rotate, and the roller 61 also drives another roller 61 to rotate in the opposite direction through two mutually meshing gears 62, so that the bracket 1 will not be damaged during the process of being clamped and moved by the two rollers 61;

[0046] It should be noted that the roller 61 also drives the two camshafts 63 to rotate, so that the protruding end of the camshaft 63 continuously pushes one end of the trigger plate 55 to rise, and vice versa, the other end drives the baffle 56 to move outward, and the second notch 57 will be exposed at this time, and the coating material inside the shunt box 51 flows downward to the surface of the roller 61, and is rolled onto the surface of the thermal insulation film 2 through the roller 61. When the protruding end of the camshaft 63 no longer contacts the trigger plate 55, the tension spring 54 pulls the baffle 56 to the side of the shunt box 51 through the trigger plate 55, and the coating material inside the shunt box 51 will not flow out from the second notch 57;

[0047] After the roller 61 rotates one circle, the coating material stained on it is evenly coated on the surface of the insulation film 2, and the protruding end of the cam shaft 63 will push one end of the trigger plate 55 up again, and then repeat the previous working process. After working for a long time, the excess coating material on the roller 61 will flow into the inside of the reflux box 71, thereby further reducing the waste of coating material and preventing the insulation film 2 from being over-coated.

[0048] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the rolling assembly 6 also includes a reciprocating threaded rod 66 fixedly mounted on the support plate 10 and located inside the roller 61. The outer peripheral thread sleeve of the reciprocating threaded rod 66 is provided with a limit frame 67. The limit frame 67 is hinged on one side close to the motor 4 with two extrusion plates 68. A cover plate 69 is movably connected to one side of the roller 61.

[0049] The reflux assembly 7 also includes a feed pipe 73 connected to the interior of the reflux box 71 . The feed pipe 73 is connected to the interior of the roller 61 through the cover plate 2 69 . A scraper 72 is fixedly mounted on the side of the reflux box 71 .

[0050] A partition is provided on one side of the limiting frame 67 close to the second cover plate 69 , and two extrusion plates 68 are hinged to the other side of the limiting frame 67 , and the extrusion plates 68 are made of rubber.

[0051] The rolling assembly 6 also includes a cover plate 64 clamped on the side of the roller 61 . The interior of the roller 61 is connected to a discharge pipe 65 through the cover plate 64 . The end of the discharge pipe 65 is connected to the interior of the reflux box 3 .

[0052] The above scheme is adopted: the roller 61 is driven to rotate by the output shaft of the motor 4, but the reciprocating threaded rod 66 is fixed on the support plate 10, which makes the limit frame 67 move axially according to the thread groove on the reciprocating threaded rod 66 during the rotation of the roller 61. When the limit frame 67 moves toward the side of the motor 4, the extrusion plate 68 is close to the side of the limit frame 67, so that the coating material inside the reflux box 71 is extracted through the feed pipe 73. Similarly, the limit frame 67 will also extrude the material in conjunction with the extrusion plate 68, so that it enters the inside of the reflux box 3 through the discharge pipe 65, and then waits for the next use. Furthermore, material waste is avoided;

[0053] When the limit frame 67 moves in the reverse direction, the extrusion plate 68 is impacted by the liquid material and becomes open. When the limit frame 67 moves to the end closest to the second cover plate 69 through the threaded groove, the limit frame 67 will move toward the direction of the motor 4 again, thereby reciprocatingly extracting the material retained in the reflux box 71.

[0054] like Figure 1 , Figure 2 , Figure 5 , Figure 7 and Figure 8 As shown, the reflux assembly 7 also includes a chain 75 drivingly connected to both sides of the roller 61 , a threaded conveying rod 74 is installed on the internal bearing of the reflux box 71 , and the roller 61 is drivingly connected to the threaded conveying rod 74 through the chain 75 .

[0055] The above solution is adopted: the roller 61 drives the threaded conveying rod 74 to rotate through the chain 75, and the inner wall of the reflux box 71 is semicircular, so that the outer side of the threaded conveying rod 74 can scratch the inner wall of the reflux box 71, and the threaded design of the threaded conveying rod 74 allows the coating material inside the reflux box 71 to flow to the end of the feed pipe 73 and be extracted by the limit frame 67, further avoiding material waste.

[0056] like Figure 6 As shown, the diversion assembly 5 also includes a cleaning tube 52 fixedly mounted on the diversion box 51, and both ends of the cleaning tube 52 are connected to the interior of the roller 61 through cover plate 2 69 and cover plate 1 64 respectively. First slots 53 are equidistantly provided on the cleaning tube 52, and the opening of the first slot 53 faces the side of the thermal insulation film 2.

[0057] The above scheme is adopted: in the process of the limit frame 67 and the extrusion plate 68 extruding the material into the reflux box 3, the air inside the roller 61 will also be squeezed into the inside of the cleaning tube 52, and finally discharged to the side of the thermal insulation film 2 through the first slot 53, so as to ensure that the surface of the thermal insulation film 2 is completely dry and free of dust after the coating process in the previous workstation, thereby improving the quality of the thermal insulation film 2 after coating.

[0058] The working principle and use process of the present invention:

[0059] When the thermal insulation film 2 is in the working state, the motor 4 is started, so that the output shaft of the motor 4 drives the roller 61 to rotate, and the roller 61 also drives another roller 61 to rotate in the opposite direction through two mutually meshing gears 62;

[0060] The roller 61 drives the protruding ends of the two camshafts 63 to continuously push one end of the trigger plate 55 upward, and vice versa, the other end drives the baffle 56 to move outward, and the second notch 57 exposes the coating material and flows downward to the surface of the roller 61, and the coating material is rolled onto the surface of the bracket 1 through the roller 61. When the protruding end of the camshaft 63 no longer contacts the trigger plate 55, the tension spring 54 pulls the baffle 56 to the side of the shunt box 51 through the trigger plate 55, and the coating material inside the shunt box 51 will not flow out from the second notch 57;

[0061] After the roller 61 rotates one circle, the coating material on it is evenly coated on the surface of the bracket 1, and the protruding end of the cam shaft 63 will push one end of the trigger plate 55 up again, and then repeat the previous working process. After working for a long time, the excess coating material on the roller 61 will flow into the inside of the reflux box 71;

[0062] The roller 61 drives the threaded conveying rod 74 to rotate through the chain 75, and the inner wall of the reflux box 71 is semicircular, so that the outer side of the threaded conveying rod 74 can scrape the inner wall of the reflux box 71, and the threaded design of the threaded conveying rod 74 allows the coating material inside the reflux box 71 to flow to the end of the feed pipe 73, and the limit frame 67 will move axially according to the thread groove on the reciprocating threaded rod 66. When the limit frame 67 moves toward the side of the motor 4, the extrusion plate 68 is close to the side of the limit frame 67, so that the coating material inside the reflux box 71 is extracted through the feed pipe 73. Similarly, the limit frame 67 will also work with the extrusion plate 68 to extrude the material, so that it passes through the discharge pipe 65 and enters the interior of the reflux box 3, and then waits for the next use;

[0063] In the process of the limiting frame 67 and the extrusion plate 68 extruding the material into the reflux box 3, the air inside the roller 61 will also be squeezed into the inside of the cleaning tube 52, and finally discharged to the side of the thermal insulation film 2 through the first slot 53, thereby ensuring that the surface of the thermal insulation film 2 is completely dry and free of dust after the coating process in the previous workstation.
