Description

Technical Field

[0001] The invention relates to the technical field of polycarbonate film processing devices, in particular to a texture pressing device for a polycarbonate film. Background Art

[0002] Polycarbonate is referred to as PC. It is a film made of polycarbonate resin as the base material. It has the advantages of good toughness, high strength and not easy to tear and break. It is widely used in various fields. In the production process of polycarbonate film, it is necessary to emboss the polycarbonate film through an embossing device to form a specific texture on its surface so as to better meet the actual use needs. However, the existing texture pressing device for polycarbonate film mainly performs cold pressing through an adjustable pressing roller. During the pressing process, this texture pressing method mainly achieves the texture pressing effect by applying pressure to the film through the pressing roller, which can easily lead to problems such as unclear pressed texture. Therefore, in view of the above problems, a texture pressing device for polycarbonate film is designed to better meet the actual use needs. Summary of the invention

[0003] The object of the present invention is to provide a texture pressing device for polycarbonate film to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a texture pressing device for polycarbonate film, comprising a base plate, a fixed frame, a first embossing roller and a second embossing roller, a fixed frame is vertically fixed on the base plate, a motor is fixed on the fixed frame, the output end of the motor is connected to the first embossing roller, the first embossing roller bearing is connected to the fixed frame, an oil cylinder is fixed on the upper end face of the fixed frame, the output end of the oil cylinder passes through the fixed frame and is fixed to a movable plate, a second embossing roller is connected to the bearing on the movable plate, the second embossing roller is located directly above the first embossing roller, the second embossing roller and the first embossing roller are both in contact with the film body, a fixed box is also fixed on the upper end face of the base plate, the fixed box is located directly below the first embossing roller, and two cylinders fixed to the upper end face of the base plate are symmetrically arranged on the left and right sides of the fixed box.

[0005] Preferably, the fixing frames are symmetrically distributed about the center line of the base plate, and four connecting rods are fixed between the two fixing frames, and the connecting rods are distributed parallel to the first embossing roller. Through the action of the four connecting rods, the supporting and fixing effect between the two fixing frames can be achieved, thereby ensuring the stability of the installation of the fixing frames.

[0006] Preferably, a mounting frame is symmetrically fixed to the fixed frame, and a movable frame is arranged below the mounting frame, and the movable frame is symmetrically distributed front to back about the center line of the first embossing roller. Through the action of the mounting frame and the movable frame, basic guarantee can be provided for the installation of the clamping mechanism.

[0007] Preferably, a guide roller is connected to the bearing on the movable frame, and the height of the lower end surface of the guide roller is lower than the height of the upper end surface of the first embossing roller. Vertical rods are symmetrically fixed on the movable frame, and the vertical rods are slidably connected to the mounting frame. One end of a spring is fixed to the movable frame, and the other end of the spring is fixed to the mounting frame. During the use of the device, the guiding effect of the film body can be achieved through the guide roller, and the elastic effect of the spring can provide a force for the film body, thereby achieving the tensioning effect of the film body, thereby ensuring the flatness of the film body on the first embossing roller, thereby ensuring the pressing effect of the texture, and when the movable frame moves, the stability of the movement of the movable frame can be ensured by the sliding guiding effect between the vertical rod and the mounting frame.

[0008] Preferably, two cams are fixed on the first embossing roller, and the convex edges of the two cams are in opposite positions. A driving gear is also fixed on the first embossing roller, and the driving gear is located on the outside of the fixed frame.

[0009] Preferably, the first embossing roller and the second embossing roller are distributed in parallel, and the length of the first embossing roller is equal to the length of the second embossing roller, and the length of the first embossing roller is smaller than the length of the guide roller. By limiting the length of the first embossing roller, the normal texture pressing on the film body can be ensured.

[0011] Preferably, heating rods are evenly fixed on the fixed box and are located directly below the first embossing roller. An air duct is also fixed in the fixed box and nozzles are evenly installed on the air duct. The heating effect of the first embossing roller can be achieved through the action of the heating rod, so that the first embossing roller has a certain temperature, thereby ensuring the pressing effect of the first embossing roller on the film body. In combination with the action of the air duct and the nozzle, the hot air generated by the heating rod can be evenly diffused to the first embossing roller, thereby achieving uniform heating of the first embossing roller and further ensuring the pressing effect of the texture.

[0012] Preferably, two one-way valves are installed on the cylinder, and the one-way valve on the cylinder close to the fixed box is connected to the air duct through a conduit. Through the action of the two one-way valves, the gas flow direction of the cylinder can be controlled to ensure the normal operation of the device.

[0013] Preferably, a sliding rod is slidably connected to the cylinder, and a piston head is fixed at the lower end of the sliding rod, and the piston head is nested in the cylinder and can slide up and down. A spherical rod is also fixed to the upper end of the sliding rod, and the spherical rod is nested in the groove on the cam and can slide. Through the sliding action between the spherical rod and the cam, the sliding rod and the piston head can be forced to move up and down in an orderly manner. Through the sliding action between the piston head and the cylinder, the exhaust function of the cylinder can be realized, thereby providing basic guarantee for the normal operation of the device.

[0026] The fixed frame 2 is symmetrically distributed with respect to the center line of the bottom plate 1, and four connecting rods 3 are fixed between the two fixed frames 2, and the connecting rods 3 are parallelly distributed with the first embossing roller 7; the fixed frame 2 is also symmetrically fixed with a mounting frame 4, and a movable frame 5 is arranged below the mounting frame 4, and the movable frame 5 is symmetrically distributed with respect to the center line of the first embossing roller 7; the movable frame 5 is connected to a guide roller 501 by a bearing, and the height of the lower end surface of the guide roller 501 is lower than the height of the upper end surface of the first embossing roller 7, the movable frame 5 is symmetrically fixed with vertical rods 502, and the vertical rods 502 are slidably connected with the mounting frame 4, one end of a spring 503 is fixed to the movable frame 5, and the other end of the spring 503 is fixed to the mounting frame 4;

[0027] When using the polycarbonate film texture pressing device, such as Figure 1-Figure 8 As shown, firstly, the whole device is installed and powered by an external power supply. When the film body 11 is embossed, as shown in FIG. Figure 8 As shown in the figure, the film body 11 is installed with the entire device. At this time, the film body 11 is located at the lower side of the guide roller 501, and the film body 11 is located between the first embossing roller 7 and the second embossing roller 10. The movable plate 9 can be driven to move by controlling the extension of the oil cylinder 8, so as to realize the height adjustment of the second embossing roller 10, and then realize the pressure adjustment of the film body 11 to ensure the embossing effect (and when the height of the second embossing roller 10 is adjusted, the moving distance of the second embossing roller 10 is less than the meshing distance between the driven gear 1001 and the driving gear 702 to ensure the normal operation of the device). After the adjustment is completed, the film body 11 can be moved by the winding roller and the unwinding roller of the film body 11, so as to provide a continuous support for the subsequent film body 11. The embossing provides a basic guarantee. After the film body 11 is installed, the vertical rod 502 is pulled to drive the movable frame 5 and the guide roller 501 to move up a certain distance, and then the film body 11 can be in a straight state with the help of the winding roller and the unwinding roller, and the film body 11 is in contact with the guide roller 501. Finally, the vertical rod 502 is released. At this time, under the elastic action of the spring 503, a downward force can be provided to the movable frame 5 and the guide roller 501, so that the guide roller 501 generates pressure on the film body 11. Through the action of the two guide rollers 501, the film body 11 located between the first embossing roller 7 and the second embossing roller 10 can be in a straight state, thereby ensuring the flatness of the film body 11 and facilitating the subsequent embossing operation.

[0028] Two cams 701 are fixed on the first embossing roller 7, and the convex edges of the two cams 701 are in opposite positions. A driving gear 702 is also fixed on the first embossing roller 7, and the driving gear 702 is located outside the fixed frame 2; the first embossing roller 7 and the second embossing roller 10 are parallel to each other, and the length of the first embossing roller 7 is equal to that of the second embossing roller 10, and the length of the first embossing roller 7 is less than that of the guide roller 501; a driven gear 1001 is also fixed on the second embossing roller 10, and the driven gear 1001 meshes with the driving gear 702 to realize transmission, and fixed rings 1002 are fixed at equal intervals in the second embossing roller 10, and a rubber ball 1003 is rolled and placed on the fixed ring 1002, and a lead is arranged in the rubber ball 1003 ball 1004; a heating rod 1201 is evenly fixed on the fixed box 12, and the heating rod 1201 is located directly below the first embossing roller 7, an air guide tube 1202 is also fixed in the fixed box 12, and a nozzle 1203 is evenly installed on the air guide tube 1202; two one-way valves 1301 are installed on the cylinder 13, and the one-way valve 1301 on the cylinder 13 close to the fixed box 12 is connected to the air guide tube 1202 through a conduit; a sliding rod 1302 is slidably connected to the cylinder 13, and a piston head 1303 is fixed at the lower end of the sliding rod 1302, and the piston head 1303 is nested in the cylinder 13 and can slide up and down, and a spherical rod 1304 is also fixed at the upper end of the sliding rod 1302, and the spherical rod 1304 is nested in the groove on the cam 701 to slide;

[0029] After the film body 11 and the entire device are installed, Figure 1-Figure 8As shown, during the embossing operation, the first embossing roller 7 and the driving gear 702 can be driven to rotate by starting the motor 6, and the meshing transmission between the driving gear 702 and the driven gear 1001 can make the second embossing roller 10 rotate synchronously, and the film body 11 can be moved by the winding roller to generate a pulling force on the film body 11, and the embossing effect of the film body 11 can be achieved by the rolling effect of the first embossing roller 7 and the second embossing roller 10, and during the embossing process, the heating rod 1201 is started synchronously, and the heating rod 1201 is turned on and the heating rod 1201 is turned on and the heating rod 1201 is turned on. The heating rod 1201 can heat the air, and when the first embossing roller 7 rotates, the cam 701 is driven to rotate at the same time. Through the sliding action between the cam 701 and the spherical rod 1304, the spherical rod 1304 can be forced to move up and down in an orderly manner, thereby driving the sliding rod 1302 and the piston head 1303 to move up and down in an orderly manner. When the piston head 1303 moves upward, the one-way valve 1301 on the cylinder 13 away from the fixed box 12 opens, and the one-way valve 1301 on the cylinder 13 close to the fixed box 12 closes. Thus, the cylinder 13 achieves the air suction effect. When the piston head 1303 moves downward, the one-way valve 1301 on the cylinder 13 away from the fixed box 12 is closed, and the one-way valve 1301 on the cylinder 13 close to the fixed box 12 is opened, thereby achieving the exhaust effect of the cylinder 13, and the gas exhausted from the cylinder 13 enters the air guide pipe 1202 through the conduit and is ejected through the nozzle 1203. Since the nozzle 1203 is located below the heating rod 1201, the airflow ejected by the nozzle 1203 can drive the air heated by the heating rod 1201 to pass through the nozzle 1203. The first embossing roller 7 is in contact with the first embossing roller 7, thereby realizing the heating effect of the first embossing roller 7. By heating the first embossing roller 7, the hot pressing effect of the film body 11 can be realized, thereby ensuring the embossing effect of the film body 11, and because the convex edges of the left and right cams 701 on the first embossing roller 7 are in opposite positions, when the two cams 701 rotate, one of the two cylinders 13 is in an air intake state and the other is in an air exhaust state, thereby ensuring that the nozzle 1203 can continuously spray airflow and ensure the uniform heating effect of the first embossing roller 7;

[0030] A driven gear 1001 is also fixed on the second embossing roller 10, and the driven gear 1001 meshes with the driving gear 702 to achieve transmission. Fixed rings 1002 are fixed at equal intervals in the second embossing roller 10, and a rubber ball 1003 is rolled on the fixed ring 1002, and a lead ball 1004 is arranged in the rubber ball 1003;

[0031] During the embossing process of the film body 11, as Figure 1 , Figure 4 , Figure 5 and Figure 8As shown, when the second embossing roller 10 rotates, the rubber ball 1003 can move a certain distance in the fixed ring 1002 along the rotation direction of the second embossing roller 10 under the action of inertia, and then automatically fall back under the action of the gravity of the rubber ball 1003 and the lead ball 1004. During the falling process of the rubber ball 1003 and the lead ball 1004, the rubber ball 1003 and the lead ball 1004 will generate a certain downward impact force on the fixed ring 1002 and the second embossing roller 10, so that the second embossing roller 10 can generate a certain impact force on the film body 11, thereby ensuring the embossing effect of the second embossing roller 10 on the film body 11, and then effectively ensuring the embossing quality of the film body 11;

[0032] To sum up, the texture pressing equipment for polycarbonate film can realize the automatic heating effect of the first embossing roller 7 through the uniform heating mechanism, so as to realize the hot embossing effect of the film body 11, and the heating by the hot air mechanism can avoid the first embossing roller 7 from overheating and causing damage to the film body 11, and combined with the gravity impact mechanism, the second embossing roller 10 can generate a certain impact force on the film body 11, so as to further ensure the embossing effect of the film body 11 and improve the embossing quality of the film body 11. This is the working principle of the texture pressing equipment for polycarbonate film.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
