Description

Technical Field

[0001] The utility model relates to the technical field of aluminum plating machines, in particular to an anti-deviation device for aluminum plating machines. Background Art

[0002] Aluminized film is a composite flexible packaging material formed by coating a thin layer of aluminum onto a plastic film using a special process. Because it combines the characteristics of both plastic film and metal, it is an inexpensive, aesthetically pleasing, high-performance, and highly practical packaging material. Vacuum aluminized film is the most commonly used coating method. This process involves evaporating high-purity aluminum filaments at high temperatures into a gaseous state. When the plastic film passes through a vacuum evaporation chamber, the gaseous aluminum molecules precipitate onto the surface of the film, creating a bright, metallic film.

[0003] However, during the vacuum coating process, since the normal operating speed of the vacuum aluminum coating machine can reach 600m / min, during the high-speed operation, slight abnormalities such as tension and pressure will cause the film to deviate and be difficult to return to its position. Therefore, the film often deviates, resulting in problems such as film flying and film breakage, resulting in poor coating quality in the vacuum evaporation chamber, and thus a large number of defective products are produced, reducing the coating qualification rate; at the same time, after the film deviates, the machine needs to be stopped for manual inspection, and then the material roller is reversed to withdraw and readjust the film, which delays production time and affects the production progress of the coated products. Utility Model Content

[0004] In order to solve the technical problems existing in the prior art such as film deviation leading to film flying and film breakage, resulting in poor coating quality, reduced coating qualification rate, the need to stop the machine, reverse the material roller for readjustment, and delay production time and production progress, the present invention provides the following technical solutions.

[0005] The utility model discloses an anti-deviation device for an aluminum plating machine, comprising a base and a feeding roller group for film feeding connected by a feeding bracket located on the upper part of the base, the upper part of the base is also provided with a U-shaped anti-deviation bracket, and anti-deviation roller groups with the same structure and relatively arranged on both sides of the anti-deviation bracket are respectively provided, and each of the driving components drives one anti-deviation roller group, and correction sensors for monitoring the film are also provided on the opposite sides of the anti-deviation bracket, and the anti-deviation roller group comprises a first threaded roller and a second threaded roller located on the upper and lower sides of the film, the first threaded roller and the second threaded roller have the same structure and rotate in opposite directions, and the two relatively arranged anti-deviation roller groups generate outward forces on both sides when the film is running through the two relatively arranged first threaded rollers and the two second threaded rollers to prevent the film from deviating and return it to the right position.

[0006] As a further technical solution, the adjacent ends of the two first threaded rollers and the two second threaded rollers arranged opposite to each other are connected to a positioning assembly through a positioning groove.

[0007] As a further technical solution, the positioning assembly includes a connecting column and positioning ends located at both ends of the connecting column and slidably sleeved with the positioning groove.

[0008] As a further technical solution, bearings rotatably connected to the first thread roller and the second thread roller are respectively provided on both sides of the connecting column.

[0009] As a further technical solution, the driving component includes a fixing frame fixed on one side of the anti-slip bracket and a driving motor fixed on the outside of the fixing frame. The output end of the driving motor is connected to a driving gear connected to the second thread roller, and the driving gear is meshed with a driven gear connected to the first thread roller.

[0010] As a further technical solution, the threads on the outer surfaces of the first thread roller and the second thread roller are smoothed.

[0011] The beneficial effect of the utility model is that the utility model installs a correction sensor and an anti-deviation roller group in the forward direction of the film behind the feeding roller group, so that during aluminum plating, the anti-deviation roller group can generate outward force on both sides of the film when the film is moving, so that the film is smoother when passing. Because there are relative first and second threaded rollers on both sides, the contact area between the film and the rollers is increased, which is less likely to slip, and can prevent the film from deviating and return it to the right position. There is no need to stop the machine for inspection, which will not affect the production progress of the coated products, and improves the coating efficiency and coating qualification rate in the vacuum evaporation chamber.

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the present invention and are not intended to limit the present invention. It should be noted that the embodiments and features of the embodiments of the present invention may be combined with each other unless there is a conflict.

[0018] In the description of this utility model, it should be understood that the terms "upper," "lower," and "both sides" are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," etc. are used for descriptive purposes only and should not be construed to indicate or imply relative importance or implicitly specify the quantity of the technical features referred to.

[0019] like Figure 1 and Figure 2 As shown, the utility model is an anti-deviation device for an aluminum plating machine, comprising a base 1 and a loading roller group 3 located on one side of the upper part of the base 1. The loading roller group 3 is supported by a loading bracket 2. The loading roller group 3 is used to drive the film 9 to load under the drive of the power device. The loading roller group 3 adopts the existing technology and will not be repeated here.

[0020] like Figure 2 and Figure 4 As shown, in a preferred embodiment, a U-shaped anti-deviation bracket 4 is further provided on the upper portion of the base 1. The anti-deviation bracket 4 is located on one side of the feeding roller assembly 3, in the forward direction of the film 9. Anti-deviation roller assemblies 6 of identical structure and oppositely disposed are provided on either side of the anti-deviation bracket 4. The two anti-deviation roller assemblies 6 are respectively used to flatten the two sides of the film 9, preventing the film 9 from deviating and also straightening any deviated film 9.

[0021] Drive components 5 are connected to both sides of the anti-deviation bracket 4, each driving a set of anti-deviation rollers 6. On opposite sides of the anti-deviation bracket 4 are also located corrective sensors 7 for monitoring the film 9. These sensors are located between the feed roller set 3 and the anti-deviation roller set 6. When the corrective sensors 7 detect that the film 9 has deviated, the drive components 5 drive the anti-deviation roller set 6 to flatten the film 9 as it enters and exits.

[0022] In a preferred embodiment, the anti-deviation roller assembly 6 includes a first threaded roller 601 and a second threaded roller 602 located on the upper and lower sides of the film 9. To prevent the first and second threaded rollers 601, 602 from scratching the film 9 during rotation, the outer threads of the first and second threaded rollers 601, 602 are smoothed. The first and second threaded rollers 601, 602 are both rotatably connected to the anti-deviation bracket 4. The first and second threaded rollers 601, 602 have identical structures and rotate in opposite directions. The two oppositely positioned anti-deviation roller assemblies 6 generate an outward force on both sides of the film 9 as it travels, thereby preventing the film 9 from deviating and restoring it to its proper position.

[0023] Specifically, the drive component 5 drives the first threaded roller 601 and two second threaded rollers 602 of the same anti-deviation roller set 6 to rotate in opposite directions. This generates an outward force as the film 9 travels, preventing the film from deviating and restoring it to its proper position even after it has deviated. Thus, the two drive components 5 drive the two anti-deviation roller sets 6, respectively, generating an outward force on both sides of the film 9 as it travels, preventing the film 9 from deviating.

[0024] In this embodiment, the two opposing first thread rollers 601 and the two second thread rollers 602 are each provided with a positioning groove 603 at their proximal ends. The positioning grooves 603 are rotatably connected to a positioning assembly 8. The positioning assembly 8 comprises a connecting post 801 and positioning ends 803 located at either end of the connecting post 801, which slidably engage the positioning grooves 603. Bearings 802 are provided on either side of the connecting post 801, respectively, to rotatably connect with the first and second thread rollers 601, 602. This ensures that the two anti-deviation roller assemblies 6 can maintain relative positioning during their respective rotations, preventing axial deviation of the first and second thread rollers 601, 602.

[0025] like Figure 3 As shown, in another embodiment, the positioning assembly 8 may not be provided, and the two anti-deviation roller groups 6 do not affect each other when they rotate separately. It is sufficient as long as they can prevent the film 9 from deviating and return it to the right position after deviating.

[0026] In the above embodiment, the drive component 5 includes a mounting bracket 501 fixed to one side of the anti-deviation bracket 4 and a drive motor 502 fixed to the outside of the mounting bracket 501. The output end of the drive motor 502 is connected to a driving gear 503 connected to the second threaded roller 602. The driving gear 503 is meshedly connected to a driven gear 504 connected to the first threaded roller 601. Driven by the drive motor 502, the first threaded roller 601 and the second threaded roller 602 rotate in opposite directions to prevent the film 9 from deviating.

[0027] During use, the present invention feeds the film 9 via the feed roller assembly 3 and passes through the deflection correction sensor 7 and two anti-deviation roller assemblies 6. When the film 9 is not deflecting, the two anti-deviation roller assemblies 6 run at the same speed as the feed roller assembly 3, ensuring a normal feeding speed for the film 9. When the deflection correction sensor 7 detects that the film 9 is deflecting, the drive component 5 corresponding to the deflected side drives the anti-deviation roller assemblies 6 to accelerate. If both sides of the film 9 deflect, both anti-deviation roller assemblies 6 accelerate, ensuring an outward pull on the film 9 while preventing excessive speed from adversely affecting the feeding process.

[0028] The preferred specific implementation methods and embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above implementation methods and embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes or equivalent substitutions can be made without departing from the concept of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments that fall within the scope of the claims of this application belong to the scope of protection of the present invention.
