Description

Technical Field

[0001] This invention relates to the field of polycarbonate film printing, and more particularly to a device for improving the scratch resistance of polycarbonate films. Background Technology

[0002] Polycarbonate film is a high-performance engineering plastic film with a range of excellent properties, making it widely used in many fields.

[0003] In the printing industry, existing products are prone to scratches on the non-printing surfaces during the printing process, as they are dragged across the printing table. This scratches affect the product's visual appeal, leading to a large number of scrapped products and severely impacting the customer's production yield and the production company's reputation for quality.

[0004] Therefore, a device for improving the scratch resistance of polycarbonate films has been developed, which can increase the scratch resistance of polycarbonate films, improve the production yield of polycarbonate films, and reduce material waste. Summary of the Invention

[0005] In order to overcome the shortcomings of the background technology, which is to refine it into a few points that are few and precise, the present invention provides a device for improving the scratch resistance of polycarbonate film, increasing the production yield of polycarbonate film, and reducing material waste.

[0006] The technical solution of the present invention is as follows: a device for improving the scratch resistance of polycarbonate film, comprising a base, a support frame, an embossing mechanism and a guiding mechanism. There are two bases, and the support frame is connected to the top of each base. The embossing mechanism for embossing the polycarbonate film is provided between the upper parts of the support frames, and the guiding mechanism for guiding the embossed polycarbonate film is provided on the upper left side of the support frame.

[0007] As a preferred embodiment of the present invention, the embossing mechanism includes a first embossing roller, a motor, a second embossing roller, a hydraulic cylinder, a connecting member, and a spring. The first embossing roller is rotatably connected to the upper part of the support frame. The motor is connected to the upper part of the support frame on opposite sides. The output shaft of each motor is connected to the first embossing roller. The hydraulic cylinder is connected to the upper sides of both the front and rear parts of the base. The connecting member is slidably connected between the telescopic ends of adjacent hydraulic cylinders. The spring is connected to the lower sides of both the left and right parts of the connecting member between adjacent hydraulic cylinders. The second embossing roller is rotatably connected between the connecting members. The support frame is slidably connected to the second embossing roller. The extension and retraction of the hydraulic cylinder controls the up and down movement of the second embossing roller. When the second embossing roller moves downward, it facilitates the entry of the polycarbonate film between the first and second embossing rollers. When the second embossing roller moves upward, it fits against the first embossing roller, pressing the polycarbonate film. The motor controls the rotation of the first embossing roller to perform the embossing operation on the polycarbonate film.

[0008] As a preferred embodiment of the present invention, the first embossing roller and the second embossing roller are two rigid rollers with the same medium roughness.

[0009] As a preferred embodiment of the present invention, the guiding mechanism includes a first guide frame, a mounting rod, a rotating cylinder, a first lead screw, and a fastening knob. The first guide frame is connected to the upper left side of the support frame. The mounting rod is slidably connected between the first guide frames. The mounting rod can be removed from the first guide frame. The rotating cylinder is slidably and rotatably connected to the middle of the mounting rod. Limiting discs are provided on both the front and rear sides of the rotating cylinder. The first lead screw is connected to both the front and rear parts of the mounting rod. The fastening knob is threadedly connected to the first lead screw. The fastening knob is pressed and engaged with the adjacent first guide frame. The rotating cylinder on the mounting rod can press and adhere the top of the pressed polycarbonate film. When the polycarbonate film is discharged after pressing, it is guided by the rotating cylinder.

[0010] As a preferred embodiment of the present invention, a clamping mechanism is further included. The clamping mechanism includes a connecting sleeve, a second lead screw, and a clamping frame. The connecting sleeve is slidably connected to both the front and rear parts of the mounting rod. The connecting sleeve is in contact with the rotating cylinder. The second lead screw is rotatably connected to the bottom of each connecting sleeve. The clamping frame is threadedly connected to the lower part of the second lead screw. Rotating the second lead screw causes the clamping frame to move upward. The upward movement of the clamping frame cooperates with the rotating cylinder to clamp the polycarbonate film, facilitating the movement and guidance of the portion of the polycarbonate film that has just been pressed and exported.

[0011] As a preferred embodiment of the present invention, it further includes a correction mechanism, which includes a fixed base, an electric push rod, and a connecting plate. The fixed base is connected to both the left and right sides of the mounting rod, and the electric push rod is connected to the upper part of each fixed base. The connecting plate is connected to the extension and retraction of each electric push rod, and each connecting plate is connected to an adjacent connecting sleeve. The extension and retraction of the electric push rod controls the connecting plates to move closer or further apart from each other, and the connecting sleeve is controlled to move by the connecting plate. The connecting sleeve pushes the rotating cylinder to move back and forth on the mounting rod, and the rotating cylinder corrects the deviation of the pressed polycarbonate film.

[0012] As a preferred embodiment of the present invention, a stretching mechanism is further included. The stretching mechanism includes a connecting seat, a rotating frame, a rotating roller, and a torsion spring. The connecting seat is connected to the lower sides of both the front and rear parts of the clamping frame. The rotating frame is rotatably connected to the lower sides of the connecting seats that are far apart from each other. The rotating roller is rotatably connected to the upper right parts of the rotating frame. The torsion spring is connected between each rotating frame and the adjacent connecting seat. When the clamping frame clamps the polycarbonate film upward, it drives the rotating frame and the rotating roller to move upward through the connecting seat. When the rotating roller moves upward, it lifts the bottom of the polycarbonate film, lifts and tensions the pressed polycarbonate film, and improves the winding tightness of the wound polycarbonate film.

[0013] As a preferred embodiment of the present invention, a cutting mechanism is further included. The cutting mechanism includes a second guide frame, a sliding frame, and a cutting blade. The second guide frame is connected to the mounting rod. The sliding frame is slidably connected to the front of the second guide frame. The cutting blade is connected to the upper part of the sliding frame. The sliding frame drives the cutting blade to slide back and forth on the second guide frame, which can cut off the waste portion of the polycarbonate film that has just been pressed and exported, ensuring the flatness of the exported side of the polycarbonate film.

[0014] Compared with the prior art, the present invention has the following advantages: 1. The present invention uses two rigid rollers with the same medium roughness to press the polycarbonate film to achieve the effect of increasing the scratch resistance of the polycarbonate film, improving the production yield of polycarbonate film, and reducing material waste.

[0015] 2. The present invention can press and adhere the top of the pressed polycarbonate film by means of the rotating cylinder on the mounting rod. When the polycarbonate film is exited after pressing, it is guided by the mounting cylinder to ensure the stability of the polycarbonate film at the exit point, which facilitates subsequent winding.

[0016] 3. When the clamping frame of the present invention clamps the polycarbonate film upward, it will drive the rotating frame and rotating roller to move upward through the connecting seat. When the rotating roller moves upward, it lifts the bottom of the polycarbonate film, which can lift and tension the pressed polycarbonate film and improve the winding tightness of the wound polycarbonate film.

The first guide frame 40 is connected to the upper left side of the support frame 2. The mounting rod 41 is slidably connected between the first guide frames 40. The mounting rod 41 can be removed from the first guide frame 40. The rotating cylinder 42 is slidably and rotatably connected to the middle of the mounting rod 41. Limiting discs are provided on both the front and rear sides of the rotating cylinder 42. The first lead screw 43 is connected to both the front and rear parts of the mounting rod 41. The fastening knob 44 is threadedly connected to the first lead screw 43. The fastening knob 44 is pressed and engaged with the adjacent first guide frame 40.

[0031] like Figure 1 , Figure 2 and Figure 5 As shown, it also includes a clamping mechanism 5, which includes a connecting sleeve 50, a second lead screw 51, and a clamping frame 52. The connecting sleeve 50 is slidably connected to both the front and rear parts of the mounting rod 41. The connecting sleeve 50 is in contact with the rotating cylinder 42. The bottom of the connecting sleeve 50 is rotatably connected to the second lead screw 51. The clamping frame 52 is threadedly connected between the lower parts of the second lead screw 51.

[0032] like Figure 1 , Figure 2 and Figure 5 As shown, it also includes a correction mechanism 6, which includes a fixed base 60, an electric push rod 61 and a connecting plate 62. The fixed base 60 is connected to both the left and right sides of the mounting rod 41. The electric push rod 61 is connected to the upper part of the fixed base 60. The connecting plate 62 is connected to the extension and retraction of the electric push rod 61. The connecting plate 62 is connected to the adjacent connecting sleeve 50.

[0033] like Figure 1 , Figure 2 and Figure 6 As shown, it also includes a tensioning mechanism 7, which includes a connecting seat 70, a rotating frame 71, a rotating roller 72, and a torsion spring 73. The connecting seat 70 is connected to the lower sides of both the front and rear parts of the clamping frame 52.

The rotating roller 72 is rotatably connected to the upper right part of the rotating frame 71. The torsion spring 73 is connected between each rotating frame 71 and the adjacent connecting seat 70.

[0034] like Figure 1 , Figure 2 , Figure 7 and Figure 8As shown, it also includes a cutting mechanism 8, which includes a second guide frame 80, a sliding frame 81 and a cutting blade 82. The second guide frame 80 is connected to the mounting rod 41, the sliding frame 81 is slidably connected to the front of the second guide frame 80, and the cutting blade 82 is connected to the upper part of the sliding frame 81.

[0035] In use, the hydraulic cylinder 33 is activated, and its extension and retraction control the second embossing roller 32 to move up and down. When the second embossing roller 32 moves downward, it facilitates the entry of the polycarbonate film between the first embossing roller 30 and the second embossing roller 32. When the second embossing roller 32 moves upward, it comes into contact with the first embossing roller 30, pressing the polycarbonate film firmly. The motor 31 controls the rotation of the first embossing roller 30 to perform the embossing operation on the polycarbonate film. During the embossing operation, the mounting rod 41 is slid to adjust its position on the first guide frame 40. The rotating cylinder 42 is moved by the mounting rod 41 to the point where the polycarbonate film has just been embossed and exported. The rotating cylinder 42 on the mounting rod 41 can press and adhere to the top of the pressed polycarbonate film. When the polycarbonate film is exported after pressing, it is guided by the rotating cylinder 42. After the rotating cylinder 42 contacts the polycarbonate film, the second lead screw 51 is rotated to move the clamping frame 52 upward. The upward movement of the clamping frame 52 cooperates with the rotating cylinder 42 to clamp the polycarbonate film, facilitating the processing of the portion of the polycarbonate film that has just been pressed and exported. The sliding frame 52 guides the movement of the polycarbonate film and simultaneously stretches the portion of the polycarbonate film that has just been pressed and exported, preventing deformation. When the clamping frame 52 clamps the polycarbonate film upwards, it drives the rotating frame 71 and the rotating roller 72 upwards via the connecting seat 70. As the rotating roller 72 moves upwards, it lifts the bottom of the polycarbonate film, providing tension and improving the tightness of the wound polycarbonate film. Since the edge of the exported portion of the newly pressed polycarbonate film may be uneven, the sliding frame 81 can drive the cutting blade 8... 2. The polycarbonate film can be slid back and forth on the second guide frame 80 to cut off the waste portion of the polycarbonate film that has just been pressed and exported, ensuring the flatness of the exported side of the polycarbonate film. Then, the part of the polycarbonate film that has just been pressed and exported is exported and wound up by the winding device. The electric push rod 61 controls the connecting plates 62 to move closer or further apart, and controls the connecting sleeve 50 to move through the connecting plates 62. The connecting sleeve 50 pushes the rotating cylinder 42 to move back and forth on the mounting rod 41. The rotating cylinder 42 corrects the deviation of the pressed and exported polycarbonate film to ensure the winding accuracy of the polycarbonate film.

[0036] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
