Description

Technical Field

[0001] The utility model relates to the technical field of steel plate film covering, and more specifically, to a film deviation rectifying mechanism of a steel plate film covering machine. Background Art

[0002] During the processing and transportation of steel plates, oxidation may occur, or there may be adverse conditions such as being scratched by collision. Therefore, it is necessary to cover a protective film on the surface of the steel plate before transportation;

[0003] After retrieval, the existing patent (publication number: CN220996949U) discloses a real-time deviation rectifying mechanism of a film covering machine, which includes two side plates. Four support legs are provided at the bottom ends of the two side plates. A conveyor belt is provided between the two side plates. A support plate is provided on the opposite side of the side plates. A cleaning component is provided on one side of the side plates. A lifting component is provided on the other side of the support plate. A deviation rectifying component for rectifying the XPS board is provided on the side of the lifting component close to the cleaning component. A film covering component is provided on the side of the lifting component far from the cleaning component. A limiting component for limiting the XPS board is provided between the film covering component and the deviation rectifying component. Through the mutual cooperation of the deviation rectifying roller, the first motor, the first bevel gear, the second bevel gear, the lead screw, the spring, the fixing plate and the deviation rectifying detector, the utility model can detect the deviation angle of the XPS board and directly control the left and right movement of the deviation rectifying roller to rectify the XPS board, reduce the reaction time in the deviation rectifying process, and improve the deviation rectifying efficiency. The inventor found the following problems in the process of implementing the utility model:

[0004] Due to the different adhesiveness of the film covering at different temperatures, and during the film covering process, the movement state of the film will affect the effect of the hot air. The film in the area before film covering is in a stretched state, while the film in the area after film covering has already adhered to the steel plate, resulting in different temperatures in different areas of the film. This uneven heating will cause the film to deviate during the film covering process, affecting the film covering effect;

[0005] Therefore, a film deviation rectifying mechanism of a steel plate film covering machine is proposed for the above problems. Summary of the Utility Model

[0026] Embodiment 1

[0027] As shown in the attached Figures 1 to 6 A film deviation correction mechanism for a steel plate film laminating machine, including a driving roller 1, a film laminating roller 7, a rotatable hot air pipe 10 and a deviation correction plate 14. A conveyor belt 2 is sleeved on the outer surface of the driving roller 1. There are three groups of driving rollers 1. Support legs 3 are provided on both sides of two of the driving rollers 1. Connecting frames 4 are welded to the opposite surfaces of each two groups of support legs 3 in the horizontal direction. A gantry 6 is provided at the upper ends of the two connecting frames 4. The film laminating roller 7 is arranged in the inner cavity of the gantry 6. A support plate 16 is provided on the left side of the upper end of the gantry 6. There are two groups of support plates 16. The deviation correction plate 14 is arranged on one side of the opposite surfaces of the two support plates 16. A film inlet 141 is opened in the inner cavity of the deviation correction plate 14;

[0028] Fixed seats 9 are provided on the right sides of the upper ends of the two connecting frames 4. A second motor 18 is provided in front of one of the fixed seats 9. The rotatable hot air pipe 10 is installed on the opposite surfaces of the two fixed seats 9, and air outlets 101 are opened on the outer surface of the rotatable hot air pipe 10. A blower 11 is installed above one of the fixed seats 9. A heating box 12 is provided on the left side of the blower 11. Heating rods 121 are arranged in the inner cavity of the heating box 12.

[0029] Among them: The driving roller 1 can drive the conveyor belt 2 to rotate through rotation, and is fixedly connected through the support legs 3 and the connecting frames 4. The film laminating roller 7 performs film laminating operations on the steel plate on the gantry 6. The film inlet 141 in the deviation correction plate 14 is used for the film to pass through. When it is necessary to perform hot air blowing on the area where the film contacts the steel plate, the blower 11 generates air flow. The heating box 12 heats the transmitted air flow through the heating of the heating rods 121, and then the hot air is transported through the fixed seat 9 to the rotatable hot air pipe 10, and is evenly blown through a plurality of air outlets 101 on the surface of the rotatable hot air pipe 10. Then, the rotatable hot air pipe 10 is rotated for angle adjustment through the output end of the second motor 18 to ensure that the area where the film contacts the steel plate can be adaptively adjusted for blowing, ensuring that the hot air evenly covers the entire contact area and avoiding local overheating or insufficiency.

[0030] Embodiment 2

[0031] Based on Embodiment 1, the solution in Embodiment 1 will be further refined and introduced in combination with the following specific working methods, such as Figures 1 to 6As shown below, details are described as follows:

[0032] As a preferred embodiment, first electric push rods 8 are arranged on both sides of the upper end of the gantry 6. A discharge roller 17 is arranged on the left side of the deviation rectifying plate 14. The output ends of the two groups of first electric push rods 8 are respectively connected to both ends of the film covering roller 7 through rotating shafts. Further, the discharge roller 17 is used for installing the film and discharging it. Subsequently, the first electric push rods 8 perform telescopic adjustment on the film covering roller 7 on the gantry 6, thereby driving the film covering roller 7 to perform vertical lifting movement.

[0033] As a preferred embodiment, the output end of the blower 11 is communicated with the heating box 12, and the heating box 12 is communicated with the rotatable hot air pipe 10 through the through-fixed seat 9. Further, the blower 11 can transmit air flow into the heating box 12, and the heating box 12 conveys the air flow to the rotatable hot air pipe 10 through the air flow.

[0034] As a preferred embodiment, a first motor 5 is arranged behind one of the support legs 3. The first motor 5 is connected to the driving roller 1 through the support leg 3. Further, the output end of the first motor 5 can penetrate through the support leg 3 and then be connected to the driving roller 1 for output rotation.

[0035] As a preferred embodiment, a connecting rod 13 is arranged on the right side of the front end of one of the support plates 16, and a second electric push rod 15 is arranged on the right side of the front end of the other support plate 16. The output end of the second electric push rod 15 is connected to one end of the deviation rectifying plate 14. Further, the deviation rectifying plate 14 can be telescopic by connecting the second electric push rod 15, thereby driving the deviation rectifying plate 14 to perform reciprocating telescopic movement between the two support plates 16.

[0036] As a preferred embodiment, the outer surface of the connecting rod 13 penetrates through the other end of the deviation rectifying plate 14, and the other end of the deviation rectifying plate 14 is movably connected to the connecting rod 13. Further, since the connecting rod 13 penetrates through the other end of the deviation rectifying plate 14 and can move on the outer surface of the connecting rod 13 during installation, when the second electric push rod 15 adjusts the telescopic length of the adjusting end, it will drive the deviation rectifying plate 14 to perform movable telescopic movement on the outer surface of the connecting rod 13.

[0037] As a preferred embodiment, the output end of the second motor 18 is connected to the rotatable hot air duct 10 through the fixing seat 9. There are several groups of air outlets 101 provided, and a grille 102 is opened at the center of each group of air outlets 101. The positions between several groups of air outlets 101 are arranged at equal longitudinal intervals; further, several groups of air outlets 101 are evenly distributed on the surface of the rotatable hot air duct 10, so as to ensure that the air flow blows out evenly through several groups of air outlets 101 concentratedly. Through the concentrated air outlet, the flow path of the air flow is clearer, reducing the vortex and chaos of the air flow, thereby improving the air flow efficiency. And when the air flow passes through the air outlet 101, it is effectively dispersed by the grille 102, avoiding the direct impact of the strong concentrated air flow, so that the air flow can be evenly distributed to the surrounding space, forming a soft air flow. The second motor 18 can drive the rotatable hot air duct 10 to rotate.

[0038] The working process of the present utility model is as follows: First, the driving roller 1 is fixedly connected to the connecting frame 4 through the support legs 3. The first motor 5 drives the driving roller 1 to rotate, which can drive the conveyor belt 2 to rotate. The two groups of first electric push rods 8 drive the film covering roller 7 to move up and down on the gantry 6 by adjusting the telescopic length, so as to better adapt to the steel plate film covering operation. The film of the discharging roller 17 between the two groups of support plates 16 passes through the film inlet 141 in the deviation rectifying plate 14. When adjustment is needed, the second electric push rod 15 drives the deviation rectifying plate 14 to perform telescopic adjustment. The second electric push rod 15 drives the deviation rectifying plate 14 to perform telescopic movement on the outer surface of the connecting rod 13 by adjusting the telescopic length of the output end. Since the film passes through the film inlet 141 of the deviation rectifying plate 14, during the reciprocating telescopic movement, the left and right adjustment of the film will be controlled, so as to perform automatic adjustment according to the needs. Subsequently, the film covers the steel plate through the film covering roller 7. When hot air blowing is required for the area where the film contacts the steel plate, the fan 11 generates an air flow, and the heating box 12 heats the transmitted air flow through the heating of the heating rod 121, and then passes through the fixing seat 9 to convey the hot air to the rotatable hot air duct 10. The several air outlets 101 on the surface of the rotatable hot air duct 10 respectively concentrate the air flow to blow on the film covering area, making the flow path of the air flow clearer. When passing through the air outlet 101, the air flow is effectively dispersed by the grid of the grille 102. Subsequently, the output end of the second motor 18 rotates the rotatable hot air duct 10 for angle adjustment to ensure that the area where the film contacts the steel plate can be adaptively adjusted for blowing, ensuring that the hot air evenly covers the entire contact area. The above is the working principle of the film deviation rectifying mechanism of a steel plate film covering machine.
