Description

Technical Field

[0001] This utility model belongs to the technical field of PETG high-gloss film production and processing equipment, specifically relating to an online membrane pressing device for PETG high-gloss film. Background Technology

[0002] PETG high-gloss film is a high-performance plastic film material, officially known as polyethylene terephthalate. During the production of PETG high-gloss film, equipment is needed to bond the PETG high-gloss film to the substrate online. Therefore, an online membrane pressing device for PETG high-gloss film is required, which can improve production efficiency and product quality.

[0003] For example, in the Chinese utility model with announcement number CN223100011U, entitled "Online Film Pressing Device for PETG High-Gloss Film", it specifically includes: a frame, an unwinding mechanism, a rolling mechanism, and a winding mechanism. The unwinding mechanism, the rolling mechanism, and the winding mechanism are all installed on the frame. The above-mentioned prior art effectively improves production efficiency and reduces labor costs by automatically unwinding, rolling, and cutting PETG high-gloss film. At the same time, it improves the cutting accuracy of PETG high-gloss film. However, after the PETG high-gloss film is cut, the PETG high-gloss film will stop being conveyed. The film roller and substrate roller holding the PETG high-gloss film will continue to rotate due to inertia, causing the PETG high-gloss film to accumulate due to continued feeding. It is not convenient to stop the rotation of the film roller and substrate roller immediately. Therefore, an online film pressing device for PETG high-gloss film is needed. Utility Model Content

[0004] The purpose of this invention is to provide an online membrane pressing device for PETG high-gloss film that is simple in structure and reasonably designed in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] An online film pressing device for PETG high-gloss film includes a base. The base has a first support column fixedly mounted on its upper side. A film roller is mounted in the middle of the first support column, and a substrate roller is mounted on one side of the first support column. A first electric telescopic rod is fixedly mounted on one side of the first support column, and a braking plate for stopping the film roller and substrate roller is fixedly mounted at the output end of the first electric telescopic rod. A second support column located on one side of the first support column is fixedly mounted on the upper side of the base. A film pressing mechanism is fixedly mounted at one end of the upper side of the second support column. A cutting mechanism for cutting the pressed PETG high-gloss film is fixedly mounted on the upper side of the base on the other side of the second support column. A winding mechanism is fixedly mounted on the upper side of the base on the other side of the cutting mechanism.

[0007] As a further optimization of this utility model, both ends of the first support column are provided with through grooves, and the two ends of the film roller and the substrate roller rotate within the through grooves.

[0008] As a further optimization of this utility model, a rotating roller is rotatably provided on the upper end of the second support column, and an electric heating rod fixed on the second support column is rotatably inserted through the inside of the rotating roller.

[0009] As a further optimization of this utility model, the film pressing mechanism includes a second electric telescopic rod fixed on a second support column. The output end of the second electric telescopic rod is fixedly provided with a connecting block that slides on the second support column. A limiting rod that slides through the second support column is fixedly provided on one side of the connecting block. An arc-shaped plate is fixedly provided on the lower side of the connecting block. A first pressure roller is rotatably provided inside the arc-shaped plate. A second pressure roller that rotates on the second support column is provided on one side of the first pressure roller.

[0010] As a further optimization of this utility model, the cutting mechanism includes a third support column fixed on the upper side of the base, a fixed roller fixedly arranged on the upper side of the third support column, a groove opened on the upper side of the fixed roller, a cutting blade slidably arranged in the groove, and a third electric telescopic rod for driving the cutting blade to rise and fall fixedly arranged inside the groove.

[0011] As a further optimization of this utility model, the winding mechanism includes a fourth pillar fixed on the upper side of the base, a winding roller for winding PETG high gloss film is rotatably arranged on the upper side of the fourth pillar, a magnetic groove is opened on one side of the winding roller, a reduction motor for driving the winding roller to rotate is fixedly arranged on one side of the fourth pillar, and a square magnetic block that engages with the magnetic groove is fixedly arranged on the output shaft of the reduction motor.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. By setting a braking plate, after the PETG high-gloss film is cut and pressed, the film roller and the substrate roller will continue to rotate due to inertia. The first electric telescopic rod drives the braking plate to fit with the film roller and the substrate roller, so that the film roller and the substrate roller can stop rotating immediately, avoiding the film roller and the substrate roller from continuing to feed material, which would cause the film material and substrate to accumulate on the base.

[0014] 2. This utility model, by setting up a film pressing mechanism, uses a second electric telescopic rod to drive the connecting block to move laterally on the second support column with the first pressure roller. When the connecting block moves, the limiting block on the connecting block slides in the groove opened on the second support column to restrict the connecting block. When the first pressure roller is moved, the distance between the first pressure roller and the second pressure roller is lengthened, which makes it easier to place the film material and the substrate between them. At the same time, the thickness of the PETG high-gloss film will be different for different use requirements. The distance between the first pressure roller and the second pressure roller can also be adjusted according to the thickness of the film material and the substrate, which is convenient for fully pressing PETG high-gloss films of different thicknesses.

[0024] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0025] Example 1

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, an online film pressing device for PETG high-gloss film includes a base 1. A first support column 2 is fixedly installed on the upper side of the base 1. Both ends of the first support column 2 are provided with through grooves 3, one in the middle and one in the upper. A film roller 4 is placed in the through groove 3 in the middle and a substrate roller 5 is placed in the through groove 3 in the upper. A first electric telescopic rod 6 is fixedly installed on one side of the first support column 2. A brake plate 7 is fixedly installed at the output end of the first electric telescopic rod 6. When cutting PETG high-gloss film, the first electric telescopic rod 6 is activated, and the first electric telescopic rod 6 drives the brake plate 7 to move, so that the brake plate 7 is in contact with the film roller 4 and the substrate roller 5, so that the film roller 4 and the substrate roller 5, which are still rotating due to inertia, are stopped, preventing the film roller 4 and the substrate roller 5 from continuing to feed material, and allowing the PETG high-gloss film and the substrate to continue to be fed.

[0027] like Figure 1 , Figure 2 , Figure 6 As shown, a second support column 8 is fixedly installed on the upper side of the base 1. The second support column 8 is located on one side of the first support column 2. A rotating roller 9 is rotatably installed on one end of the upper side of the second support column 8. An electric heating rod 10 is rotatably inserted through the inside of the rotating roller 9. The electric heating rod 10 is fixed on the second support column 8. The PETG high-gloss film and the substrate pass through the upper side of the rotating roller 9 and are attached to the upper side of the rotating roller 9. When the electric heating rod 10 is activated, the rotating roller 9 can heat the PETG high-gloss film and the substrate, which makes film pressing more convenient.

[0028] like Figure 5 , Figure 6As shown, a membrane pressing mechanism 11 is fixedly installed at one upper end of the second support column 8. The membrane pressing mechanism 11 includes a second electric telescopic rod 1101, which is fixed in a groove opened on the second support column 8. A connecting block 1102 is fixedly installed at the output end of the second electric telescopic rod 1101. The second electric telescopic rod 1101 drives the connecting block 1102 to slide on the second support column 8. A limit rod 1103 is fixedly installed on one side of the connecting block 1102. 1103 slides through the second support column 8. The limiting rod 1103 limits the movement of the connecting block 1102, ensuring smooth movement of the connecting block 1102. An arc-shaped plate 1104 is fixedly installed on the lower side of the connecting block 1102. The arc-shaped plate 1104 consists of two halves, which are fixed together by bolts. A first pressure roller 1105 is rotatably installed inside the arc-shaped plate 1104. A second pressure roller 1106 is installed on one side of the first pressure roller 1105. The second pressure roller 1106 rotates on the second support column 8. On column 8, the heated PETG high-gloss film and the substrate are pressed together by the first pressure roller 1105 and the second pressure roller 1106. When the PETG high-gloss film and the substrate pass between the first pressure roller 1105 and the second pressure roller 1106, the second electric telescopic rod 1101 is activated. The second electric telescopic rod 1101 drives the connecting block 1102 to move. The connecting block 1102 moves the first pressure roller 1105, causing the first pressure roller 1105 to move away from the second pressure roller 1106, thus pressing the PETG high-gloss film and the substrate together. After the high-gloss film and the substrate pass between the first pressure roller 1105 and the second pressure roller 1106, the second electric telescopic rod 1101 is activated again to bring the first pressure roller 1105 closer to the second pressure roller 1106 until the first pressure roller 1105 and the second pressure roller 1106 tightly clamp the PETG high-gloss film and the substrate, and press them together by squeezing. Both the first pressure roller 1105 and the second pressure roller 1106 can rotate, so it does not hinder the PETG high-gloss film and the substrate from being conveyed and pressed at the same time.

[0029] like Figure 1 , Figure 7As shown, a cutting mechanism 12 is fixedly installed on the upper side of the base 1. The cutting mechanism 12 is located on the other side of the second pillar 8 and is used to cut the PETG high-gloss film after film pressing. The cutting mechanism 12 includes a third pillar 1201, which is fixed on the upper side of the base 1. A fixed roller 1202 is fixedly installed on the upper side of the third pillar 1201. A groove 1203 is opened on the upper side of the fixed roller 1202. A cutter 1205 is slidably installed in the groove 1203. A third electric telescopic rod 1204 is fixedly installed inside the groove 1203. The third electric telescopic rod 1204 drives the cutter 1205 to move. When not cutting, the upper side of the cutter 1205 is lower. Above the fixed roller 1202, the cutter 1205 is entirely within the groove 1203. The PETG high-gloss film and substrate pass from the lower side of the pressing mechanism 11 through the upper side of the fixed roller 1202 and connect to the winding mechanism 13 on the side for winding. When the required PETG high-gloss film is wound up, it needs to be cut. At this time, the third electric telescopic rod 1204 is activated, and the third electric telescopic rod 1204 drives the cutter 1205 to move upward. The cutter 1205 cuts the PETG high-gloss film upward. After cutting, the third electric telescopic rod 1204 drives the cutter 1205 to move downward, and it is once again placed entirely within the groove 1203.

[0030] like Figure 2 , Figure 8 As shown, a winding mechanism 13 is fixedly installed on the upper side of the base 1. The winding mechanism 13 is located on the other side of the cutting mechanism 12. The winding mechanism 13 includes a fourth support column 1301, which is fixed to the upper side of the base 1. A winding roller 1302 for winding PETG high-gloss film is rotatably installed on the upper side of the fourth support column 1301. A magnetic groove 1303 is provided on one side of the winding roller 1302. A reduction motor 1304 is fixedly installed on one side of the fourth support column 1301. The reduction motor 1304 drives the winding roller 1302 to rotate. A square magnetic block 1305 is fixedly installed on the output shaft of the reduction motor 1304. The square magnetic block 1305 engages with the magnetic groove 1303 to place the winding roller 1302 onto the fourth support column 1301. The PETG high-gloss film, after being pressed, is fixed onto the take-up roller 1302. The geared motor 1304 is started, and the geared motor 1304 drives the take-up roller 1302 to rotate and wind up the PETG high-gloss film. After winding up to the required amount, the geared motor 1304 is turned off, and the take-up roller 1302 is moved away from the geared motor 1304 to disengage the square magnetic block 1305 from the magnetic groove 1303. The take-up roller 1302, along with the wound PETG high-gloss film, is removed from the fourth support column 1301. Then, a new take-up roller 1302 is placed on the fourth support column 1301, and the take-up roller 1302 is moved toward the geared motor 1304 to magnetically engage the square magnetic block 1305 with the magnetic groove 1303, allowing for rewinding.

[0031] It should be noted that, in use, this online film pressing device for PETG high-gloss film involves placing the film roller 4 and substrate roller 5 onto the first support column 2, passing the PETG high-gloss film and substrate through the upper side of the rotating roller 9, between the first pressure roller 1105 and the second pressure roller 1106, passing from the lower side through the upper side of the fixed roller 1202, and then fixing them onto the take-up roller 1302. The heating rod 10 is then turned on to heat the rotating roller 9, thereby heating the PETG high-gloss film and substrate. The reduction motor 1304 is then started to drive the take-up roller 1302 to rotate, allowing the PETG high-gloss film and substrate to be conveyed on the device. During conveying, the heated PETG high-gloss film and substrate pass through the first pressure roller 1105 and the second pressure roller 1106. The film is pressed by extrusion, and the pressed PETG high-gloss film is wound onto the take-up roller 1302. After a certain amount of PETG high-gloss film and substrate are wound up, the geared motor 1304 is turned off, causing the take-up roller 1302 to stop rotating. At the same time, the first electric telescopic rod 6 is activated, causing the first electric telescopic rod 6 to drive the brake plate 7 to move, stopping the film roller 4 and substrate roller 5 to prevent the film roller 4 and substrate roller 5 from continuing to feed material. Then, the third electric telescopic rod 1204 is activated, driving the cutter 1205 to move upward to cut the PETG high-gloss film. After cutting, the take-up roller 1302 with the PETG high-gloss film is removed from the fourth support 1301, and a new take-up roller 1302 is installed to continue winding.

[0032] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
