Description

Technical Field

[0001] The present application belongs to the field of film pasting equipment, and specifically is an automatically adjustable opposite-side film pasting mechanism. Background Art

[0002] The automatically adjustable opposite-side film-sticking mechanism is a device used to automatically attach a thin film or protective film to the surface of an object. It is widely used in industries such as electronic products, glass, metal plates, and plastic products. The working principle of the automatically adjustable opposite-side film-sticking mechanism is to install the rolled film on the material tray, place the product on the fixture and position it, and start the automatically adjustable opposite-side film-sticking mechanism; the automatically adjustable opposite-side film-sticking mechanism will automatically and accurately attach the protective film to the surface of the material according to the set position to achieve the effect of automatic film-sticking. The operator only needs to prepare and adjust the machine, and then start the machine. The automatically adjustable opposite-side film-sticking mechanism fundamentally changes the situation of low efficiency and low quality of manual film-sticking. The use of the automatically adjustable opposite-side film-sticking mechanism not only improves product quality, but also improves production efficiency.

[0003] The existing automatically adjustable opposite-side film-laminating mechanism usually has one end of the rubber-coated roller shaft fixed and the other end suspended. In this way, during the working process, the roller shaft may deform and tilt, the film-laminating error may increase, the force may be uneven, and even wrinkles may occur. Especially when the width of the film-laminating workpiece is large, the film-laminating quality may be reduced, which seriously affects the product quality. In addition, when the workpiece is placed on the automatically adjustable opposite-side film-laminating mechanism, the workpiece itself may have a certain inclination angle, and the film-laminating surface of the workpiece cannot be completely parallel to the film. There is a certain angle between the two, which causes the edge of the workpiece to scratch the film, affecting the film-laminating quality. Therefore, there is an urgent need to develop a new film-laminating equipment. Summary of the invention

[0004] In order to overcome the shortcomings of the prior art, the present application proposes an automatically adjustable opposite-side film-sticking mechanism, in which the rolling axis is evenly stressed to ensure the quality of film-sticking.

[0005] The present application solves the technical problem by adopting the following technical solutions:

[0006] An automatically adjustable opposite-side film sticking mechanism, comprising

[0007] The fixed frame includes an upper frame, a lower frame and support columns. Four support columns are fixedly installed at intervals in the middle of the upper end of the lower frame. The upper end of the four support columns is fixedly installed with the upper frame. The upper frame and the lower frame are arranged in parallel and at intervals.

[0008] A material discharge roller, which is connected to the outside of the fixed frame and is used to support the material;

[0009] A rubber-coated roller, wherein the rubber-coated roller is arranged in a fixed frame, the rubber-coated roller is coaxially sleeved on the roller shaft, and the two ends of the roller shaft are respectively connected to the upper frame and the lower frame of the fixed frame;

[0010] A scraper, wherein the scraper is arranged in a fixed frame on one side of the rubber-coated drum, the scraper is fixedly connected to a knife shaft, the knife shaft is arranged parallel to the drum shaft, and the two ends of the knife shaft are respectively connected to the upper frame and the lower frame of the fixed frame;

[0011] The support roller is rotatably connected to the support column on the other side of the rubber-coated drum and is used to support the product to be coated.

[0012] Moreover, the unloading roller, the rubber-coated roller, the scraper and the supporting roller are all arranged in two symmetrical positions relative to the center line of the fixed frame, so that the film can be applied simultaneously on the opposite sides.

[0013] Moreover, it also includes an adjustment mechanism, through which the knife shaft or the roller shaft is respectively connected to the fixed frame, the adjustment mechanism includes a fixed block, a limit pin and a spring, the ends of the knife shaft and the roller shaft on the same side are both connected to the same fixed block, a long hole is arranged in the fixed block, and the length direction of the long hole is the direction away from or approaching the product; a limit pin is installed in the long hole, and the limit pin is fixed inside the long hole in the same direction along the length direction of the long hole;

[0014] The ends of the roller shaft and the knife shaft are both provided with through holes, which are slidably mounted on the corresponding limit pins through the through holes. Springs are installed on the limit pins on the outside of the knife shaft and the roller shaft, and the springs abut against the long holes, so that the rubber-coated roller and the scraper maintain a retaining force that is pressed inward.

[0015] Moreover, a slide cylinder is installed between the fixed blocks on both sides and the corresponding upper frame or lower frame. The slide cylinder adjusts the spacing between the fixed blocks on both sides in the lateral direction, thereby being able to adjust the spacing between the rubber-coated roller and the scraper.

[0016] Moreover, during the film laminating process, the slide cylinder keeps the fixed blocks on both sides clamped toward the middle.

[0017] The advantages and positive effects of the utility model are:

[0018] 1. The simple support structure is adopted, and supporting equipment is set at both ends of the roller shaft to avoid bending and deformation of the roller shaft, so that the force is balanced during film laminating and wrinkles are avoided. It promotes the application of the automatically adjustable opposite-side film laminating mechanism in the field of large-area film laminating workpieces.

[0019] 2. Add an adjustment device at the fixing point of the roller shaft and the scraper shaft. When there is an angle between the placed workpiece and the film, the roller and the scraper can automatically adjust the angle so that it is parallel to the film, reducing manual adjustment time, improving efficiency, and improving the quality of film pasting.

[0020] 3. The roller shaft and scraper shaft are added with limiting structures to ensure that the roller and scraper are within a reasonable range when adjusting the angle, thereby improving the accuracy of the equipment.

[0021] 4. It can simultaneously apply film to opposite sides. For workpieces that require double-sided film application, it can greatly improve the efficiency of film application, save time and improve production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to make the purpose, technical solutions and advantages of this application clearer and easier to understand, the present application is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0028] See also Figure 1 As shown, an automatically adjustable opposite-side film laminating mechanism comprises a lower frame 7, a support column 5, an upper frame 2, a material discharge roller 6, a rubber coating roller 3 and a scraper 4. Four support columns 5 are fixedly installed at intervals in the middle of the upper end of the lower frame 7, and the upper frame 2 is fixedly installed at the upper ends of the four support columns 5. The upper frame 2 and the lower frame 7 are arranged in parallel and at intervals, and the upper frame 2 and the lower frame 7 are fixedly connected to form a cubic fixed frame;

[0029] The upper ends of the lower frames 7 on both sides of the support column 5 are provided with unwinding rollers 6, which are used to support the rolled film or protective film material;

[0030] A rubber-coated roller 3 is arranged in the fixed frame, and a roller shaft 10 is coaxially mounted in the rubber-coated roller 3. The two ends of the rolling shaft are respectively connected to the upper frame 2 and the lower frame 7, so that both ends of the roller shaft 10 are supported to prevent tilting and maintain stability;

[0031] A scraper 4 is arranged in a fixed frame on one side of the roller shaft 10, and the scraper 4 is used to scrape the material flat, so that the material is output flatly and the flatness of the attachment is improved; a knife shaft 13 is fixedly connected in the scraper 4, and the two ends of the knife shaft 13 are respectively connected to the upper frame 2 and the lower frame 7, so that both ends of the knife shaft 13 are supported to prevent tilting and maintain stability;

[0032] Rollers 8 are mounted on the two support columns 5 on the other side of the drum shaft 10. The rollers 8 are used to support the products to be processed. The products are connected to the external support structure to ensure that the products are in a tensioned and flat state.

[0033] See attached Figure 2 As shown, in this embodiment, the roller 8, the discharge roller 6, the rubber drum 3 and the scraper 4 are all arranged in two symmetrical positions with the center line of the fixed frame as the axis, so that the film can be applied to the opposite side of the product at the same time. The product passes between the rubber drums 3 on both sides, and the material on the discharge roller 6 passes the rubber drum 3 and then is applied to the workpiece, and then the scraper 4 further scrapes the material on the surface of the product flat. The discharge roller 6, the rubber drum 3 and the scraper 4 cooperate to achieve film application on the opposite side.

[0034] In order to adjust the position and angle of the scraper 4 and the rubber drum 3, see the attached Figure 3 As shown, the ends of the knife shaft 13 and the roller shaft 10 on the same side are connected to the same fixing block 1, and a long hole is provided in the fixing block 1, and the length direction of the long hole is the direction away from or approaching the product; a limiting nail 12 is installed in the long hole, and the limiting nail 12 is fixed inside the long hole in the same direction along the length direction of the long hole;

[0035] See attached Figure 4 As shown, the ends of the roller shaft 10 are provided with through holes, and the end structure of the knife shaft 13 is the same as the end structure of the roller shaft 10. It is slidably mounted on the corresponding limit pins 12 through the through holes. Springs 11 are installed on the knife shaft 13 and the limit pins 12 on the outside of the roller shaft 10. The springs 11 abut against the long holes, so that the rubber-coated roller 3 and the scraper 4 maintain a retaining force that is pressed in the product direction.

[0036] When there is a certain angle between the workpiece and the rubber-coated roller 3, the workpiece transmits force to the rubber-coated roller 3, so that the two ends of the rubber-coated roller 3 are subjected to different forces, resulting in different degrees of compression of the springs 11 at both ends, until the forces at both ends of the rubber-coated roller 3 are balanced. At this time, the rubber-coated roller 3 and the workpiece are parallel, which can ensure smooth film-coating processing of the workpiece.

[0037] The scraper 4 also relies on the compression of the spring 11 to make the scraper 4 and the workpiece parallel to each other, so as to achieve automatic adjustment. The angle of automatic adjustment is limited by the elastic force of the spring 11 on the rubber drum 3 axis and the scraper 4 axis and the length of the long hole, so that the angle of automatic adjustment is within a reasonable range.

[0038] See attached Figure 2 As shown, in order to match products of various specifications, a slide cylinder 9 is installed between the corresponding fixed block 1 and the upper frame 2, or between the fixed block 1 and the lower frame 7. The two slides of the slide cylinder 9 are respectively connected to the fixed blocks 1 on both sides, and the spacing between the fixed blocks 1 on both sides is adjusted horizontally, so as to adjust the spacing between the rubber coating rollers 3. In addition, during the film laminating process, the cylinder is in a closed clamping state, providing more extrusion force for the rubber coating roller.

[0039] In this embodiment, the upper and lower sliding cylinders are fixed on the lower ends of the upper frame 2 and the lower frame 7 respectively. Long grooves are provided on the lower frame 7 at positions corresponding to the roller shaft 10 and the knife shaft 13 to facilitate the adjustment and movement of the knife shaft 13 and the roller shaft 10.

[0040] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
