Description

Technical Field

[0002] Existing plastic film rolling devices are mainly used to apply patterns, colors or functional coatings on plastic films. These devices usually include one or more rolling rollers, which can be engraved rollers or coating rollers. They contact the plastic film under pressure to transfer the pattern or coating onto the film. In the background art, these devices may adopt hot pressing or cold pressing techniques to adapt to different materials and application requirements. To improve production efficiency and quality, modern rolling devices may be equipped with precise temperature control, speed regulation and tension control systems. In addition, some advanced rolling devices also integrate online monitoring and automatic adjustment functions to ensure the precise replication of patterns and the consistency of coatings. However, these devices still pose challenges in terms of operation complexity, maintenance cost, and adaptability to film thickness and material.

Detailed implementation manners

[0030] The following will describe the three embodiments of the present application in detail with reference to the accompanying drawings.

[0031] First embodiment:

[0032] Figures 1-4 As shown, a rolling device for a vapor-phase rust-proof plastic film includes a workbench 1. Conveying devices 2 for conveying the plastic film are arranged on both sides of the workbench 1. Two pairs of auxiliary rolling units 3 are installed on the workbench 1. A rolling structure 4 is fixedly connected to the upper end of the workbench 1;

[0033] The rolling structure 4 includes an upper housing 41 covering a plurality of auxiliary rolling units 3. An installation groove opposite to the auxiliary rolling units 3 is opened at the lower end of the upper housing 41. A first pressurizing device 42 is installed in the installation groove. An installation frame is connected to the movable end of the first pressurizing device 42. An active pressurizing roller 43 is rotatably connected in the installation frame. A motor for driving the active pressurizing roller 43 to rotate actively is installed on the installation frame. A transmission structure is connected between the power output end of the motor and the active pressurizing roller 43; Those skilled in the art can select appropriate motors and transmission structures in the prior art for setting; The rolling structure 4 and the auxiliary rolling units 3 cooperate to roll the vapor-phase rust-proof plastic film traction-moved by the conveying device 2;

[0034] A pair of appearance detection units 6 are installed on the workbench 1. The appearance detection units 6 are located between two adjacent auxiliary rolling units 3. The appearance detection unit 6 includes a bracket 61. An image acquisition rack 62 is fixedly connected to the bracket 61; One appearance detection unit 6 detects the appearance of the film in real time, and the other appearance detection unit 6 is started when the previous appearance detection unit 6 detects an appearance abnormality and is used to detect the position of the appearance abnormality;

[0035] A reciprocating rolling unit 7 is provided between two pairs of auxiliary rolling units 3. The reciprocating rolling unit 7 includes an electric guide rail 71 connected to a rolling structure 4. A second pressing device 72 is fixedly connected to the movable end of the electric guide rail 71. A pair of reciprocating pressing rollers 73 are connected to the movable end of the second pressing device 72 through an auxiliary frame. The reciprocating rolling unit 7 is started when both appearance detection units 6 detect that the film does not meet the set requirements.

[0036] A gas supply plate 5 that matches the position of the reciprocating rolling unit 7 is fixedly connected to the workbench 1.

[0037] The reciprocating rolling unit 7 is used for hot pressing temperature compensation and reciprocating pressing treatment; according to the change of the surface state of the film detected at the two appearance detection units 6, the operation of the reciprocating rolling unit 7 is adjusted.

[0038] A plurality of uniformly distributed air holes are formed in the gas supply plate 5. A blower is installed in the workbench 1. The output end of the blower is connected to a heater. A plurality of flow equalizing pipes communicating with the blower are installed at the lower end of the gas supply plate 5.

[0039] The auxiliary rolling unit 3 includes a bottom plate. A pair of lifting platforms are fixedly connected to the bottom plate. A bearing seat is fixedly connected to the movable end of the lifting platform. An auxiliary roller is connected between the pair of bearing seats.

[0040] When this embodiment works, first, the vapor-phase rust-proof plastic film is conveyed to the workbench 1 through the conveying device 2; during the process of the vapor-phase rust-proof plastic film moving on the workbench 1, the rolling structure 4 and the auxiliary rolling unit 3 cooperate to perform rolling treatment on it to ensure the flatness and uniformity of the film.

[0041] The appearance detection unit 6 behind the first auxiliary rolling unit 3 detects the appearance of the film in real time. When an appearance abnormality is detected, the position is marked. When the film is tractioned by a set distance (the distance between the pair of appearance detection units 6), the other appearance detection unit 6 is started and used to detect the appearance abnormality position; during the normal conveying process, the gas supply plate 5 continuously blows air to the film to prevent the film from being damaged due to long-term contact with the workbench 1; if the quality of the detected film is qualified, this section of the film is output.

[0042] If both appearance detection units 6 detect that the film does not meet the set requirements, the reciprocating rolling unit 7 is controlled to start. Then this section of the film is reset to the position of the gas supply plate 5. Then the reciprocating rolling unit 7 performs reciprocating pressing treatment on the film to improve its surface state; when the rolling unit 7 works, the number of reciprocating rolling times is adjusted according to the secondary appearance detection result.

[0043] For example, if there are obvious scratches or unevenness on the film surface, the number of reciprocating rolling passes is increased until the film surface reaches the set standard. At the same time, according to the type and position of the defects on the film surface, the pressing pressure and movement trajectory of the reciprocating pressing roller 73 are adjusted to ensure precise repair of the defect positions. In addition, if the two detection results show a large difference in the film surface condition, that is, the area change rate of the appearance defect area is less than the set threshold, then on the basis of the pressing treatment, during the reciprocating heating of the film, a hot air flow is blown onto the film through the air supply plate 5 during the reciprocating rolling process of the reciprocating rolling unit 7, so as to perform heat treatment on the film during the reciprocating rolling process, and further improve the surface performance of the film and enhance its rust prevention effect through heating.

[0044] In this embodiment, by combining multiple rolling and detection units, efficient and precise processing of the vapor-phase rust-proof plastic film is achieved, which is easy to improve product quality and production efficiency.

[0045] The second embodiment:

[0046] Among them, the same or corresponding components as those in the first embodiment are denoted by the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment will be described below. The differences between the second embodiment and the first embodiment are as follows:

[0047] Figure 5 As shown, the installation groove covers a pair of auxiliary rolling units 3. Both of the two active pressing rollers 43 are slidably arranged in the installation groove through electric slide rails. The movable end of the electric slide rail is fixedly connected to the first pressing device 42. When the two active pressing rollers 43 move towards each other to the maximum displacement, they are staggered from the auxiliary rolling units 3.

[0048] A lifting device matching the appearance detection unit 6 is installed in the workbench 1. The width of the bracket 61 matches the width of the image acquisition frame 62, and a C-shaped fixed steel beam is connected between the image acquisition frame 62 and the bracket 61. A bearing plate is laid on the upper end of the image acquisition frame 62. After the appearance detection unit 6 descends, the upper surface of the image acquisition frame 62 is aligned with the upper surface of the workbench 1.

[0049] This embodiment realizes the adjustment of the position of the active pressing roller 43 so that the active pressing roller 43 matches the plane. Compared with the two-way rolling in cooperation with the auxiliary rolling units 3, this embodiment has low energy consumption and is suitable for small-batch or low-cost production requirements.

[0050] The third embodiment:

[0051] Among them, the same or corresponding components as those in the first embodiment are denoted by the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment will be described below. The differences between the third embodiment and the first embodiment are as follows:

[0052] Figure 6It is shown that an auxiliary rolling system is further included, and the auxiliary rolling system includes a data processing module, a data acquisition module, and a control module;

[0053] The data acquisition module is used to acquire the appearance detection images of the film;

[0054] The data processing module analyzes and processes the acquired appearance detection images, identifies the appearance defects of the film (such as defects like bubbles), determines whether the film segmentation meets the set standards (such as the defect area is less than the set area), and adjusts the operating parameters of the rolling equipment according to the analysis results, such as the pressing force, rolling speed, etc.;

[0055] The control module receives the instructions from the data processing module and controls the operation of the rolling structure 4, the auxiliary rolling unit 3, the reciprocating rolling unit 7, and the appearance detection unit 6 to ensure the automation and accuracy of the entire rolling process.

[0056] The reciprocating rolling unit 7 sets the number of reciprocating rolling times of the reciprocating rolling unit 7 and whether to perform heat treatment according to the difference degree of the film surface conditions detected twice. The difference degree of the film surface conditions is determined according to the area change rate of the appearance defect areas detected twice; when the area change rate of the appearance defect area is less than the set value (that is, the difference between the area of the appearance defect area in the latter appearance detection and the area of the appearance defect area at the same position in the previous detection is greater than the set value); area change rate = (area of the latter defect - area of the former defect) / area of the former defect × 100%, and the threshold is set to ≥ 15%;

[0057] At the same time, according to the position coordinates of each appearance defect point, the pressing pressure of the reciprocating rolling unit 7 at each defect position is set, and during the movement of the reciprocating pressing roller 73 of the reciprocating rolling unit 7, further pressing treatment is performed on each appearance defect point to facilitate the elimination of defects such as wrinkles, unevenness, and bubbles;

[0058] This embodiment can achieve precise rolling and defect repair of the film, improving the uniformity and quality of the film. Through the high-precision image acquisition of the data acquisition module and the intelligent analysis of the data processing module, various appearance defects of the film can be identified in real time and accurately, and the rolling parameters can be automatically adjusted according to the defect conditions to achieve personalized rolling.

[0059] In summary, this solution realizes the efficient and precise processing of the vapor-phase rust-proof plastic film, ensures the flatness and uniformity of the film, and at the same time, through the intelligent detection and feedback mechanism, realizes the timely identification and repair of defects, which is easy to improve the qualified rate and production efficiency of the product.

[0060] Combined with the current actual requirements, the above-mentioned implementation manner adopted in this application, the protection scope is not limited thereto. Within the knowledge scope of those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of the present invention.
