Traditionally, the steel strip is coated with adhesive by passing it over a lint-free cloth soaked in adhesive. However, this method makes it difficult to precisely control the amount of adhesive applied to the steel strip, easily causing stringing of the adhesive layer on the steel strip surface. This phenomenon is particularly noticeable at the edges of the steel strip, leading to unstable bonding quality between the film and the steel strip edges. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a steel strip coating device that can uniformly coat the surface of the steel strip and avoid stringing.

Detailed Implementation

[0016] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0017] In the traditional steel strip coating process, the steel strip is coated by passing it through a lint-free cloth soaked in adhesive. However, this method makes it difficult to precisely control the amount of adhesive applied to the steel strip, especially when the amount is too large, which can easily cause stringing of the adhesive layer on the steel strip surface. This phenomenon is particularly noticeable at the edges of the steel strip, leading to unstable bonding quality between the subsequent film material and the steel strip edges. In this embodiment, the lint-free cloth coating method is replaced with atomized spraying, which can precisely control the amount of adhesive applied and effectively avoid stringing caused by excessive adhesive application. At the same time, the cover 2 is used to block the escape of adhesive, which can reduce the escape of adhesive into the workshop environment. In addition, before the steel strip 8 enters the inner cavity of the cover 2 for coating, it is first guided by a flat nozzle 22 on the cover 2 to limit its height, thereby preventing the steel strip 8 from entering at an angle and ensuring that the surface of the steel strip 8 obtains a uniform adhesive layer.

[0018] Please refer to Figures 1 to 3 As shown, the present invention provides a steel strip adhesive application device, including an atomizing nozzle 1 and a cover 2; the atomizing nozzle 1 is disposed on the top of the cover 2, the top of the cover 2 is provided with an avoidance port 21 for the atomizing nozzle 1 to spray adhesive into the inner cavity of the cover 2, and the opposite side walls of the cover 2 are provided with flat nozzles 22 for the steel strip 8 to enter and exit the inner cavity of the cover 2.

[0019] Working principle: The atomizing nozzle 1 evenly sprays the adhesive onto the surface of the steel strip in a spray form. The atomizing nozzle 1 controls the amount of adhesive dispensed, effectively preventing stringing caused by excessive adhesive application. Simultaneously, the atomizing nozzle 1 passes through the clearance opening 21 of the cover 2 to spray the steel strip 8 located inside the cavity of the cover 2, reducing adhesive leakage into the workshop environment. Furthermore, before the steel strip 8 enters the cavity of the cover 2 for adhesive application, it is guided by a flat nozzle 22 on the cover 2 to prevent it from entering at an angle, ensuring a uniform adhesive layer on the surface of the steel strip 8.

[0020] In some implementations, please refer to Figure 3 As shown, support plates 23 and limiting plates 24 are provided opposite to each other and spaced apart on the side wall of the cover 2, forming a flat mouth 22. The support plates 23 support the lower surface of the steel strip 8, and the limiting plates 24 restrict it to the upper surface of the steel strip 8, so as to prevent the steel strip 8 from tilting into the inner cavity of the cover 2 as much as possible.

[0021] In some implementations, please refer to Figure 1 and Figure 4As shown, the inlet and outlet ends of the cover 2 are equipped with limiting components 3, and the limiting components 3 have limiting spaces 31 with a width adapted to the width of the steel strip 8. The limiting components 3 restrict the steel strip 8 to both sides in the width direction to prevent the steel strip 8 from deviating when entering the inner cavity of the cover 2, so as to ensure that the surface of the steel strip 8 obtains a uniform adhesive layer.

[0022] For details, please refer to Figure 4 As shown, the limiting assembly 3 includes two limiting wheels 32 with their surfaces facing each other, forming a limiting space 31 between the two limiting wheels 32. The two limiting wheels 32 are used to limit the steel belt 8 to both sides in the width direction.

[0023] It is worth noting that, please refer to Figure 5 As shown, the limiting wheel 32 has a limiting groove 321 along the circumference of the wheel surface, and the steel strip 8 extends into the limiting groove 321 along its width direction. By extending the steel strip 8 into the limiting groove 321 along its width direction, the limiting wheel 32 can also limit and guide the height of the steel strip 8.

[0024] In one embodiment regarding adjusting the distance between the two limit wheels 32, please refer to... Figure 4 As shown, the limiting assembly 3 also includes a bracket 33 and a lead screw 34 rotatably mounted on the bracket 33. One limiting wheel 32 is rotatably mounted on the bracket 33, and a slider is threadedly connected to the lead screw 34. The other limiting wheel 32 is rotatably mounted on the slider. By rotating the lead screw 34, the corresponding limiting wheel 32 connected to the lead screw 34 can be moved, thereby adjusting the size of the limiting space 31 to accommodate steel strips 8 of various widths.

[0025] In another embodiment regarding adjusting the distance between the two limiting wheels 32, the limiting assembly 3 further includes a bracket 33 and a lead screw 34 rotatably mounted on the bracket 33. The lead screw 34 has two sections of threads with opposite directions of rotation, and sliders are threaded onto each of these two sections. The two limiting wheels 32 are rotatably mounted on the two sliders. By rotating the lead screw 34, the two limiting wheels 32 can be moved closer or further apart, thereby adjusting the size of the limiting space 31 to accommodate steel strips 8 of various widths.

[0026] It is worth noting that the lead screw 34 can be rotated manually by installing a handle, or it can be rotated electrically by a drive device such as a motor.

[0027] In some implementations, please refer to Figure 6As shown, the steel strip coating device also includes a transfer assembly 4, which includes a first linear reciprocating device 41 for driving the atomizing nozzle 1 to move along the height direction of the housing 2, and a second linear reciprocating device 42 for driving the atomizing nozzle 1 to move along the width direction of the steel strip 8. The atomizing nozzle 1 is driven to move on the top of the housing 2 by the first linear reciprocating device 41 and the second linear reciprocating device 42 to spray the surface of steel strips 8 of various widths.

[0028] It is worth noting that the first linear reciprocator 41 and the second linear reciprocator 42 can be devices with reciprocating motion moving ends, such as pneumatic cylinders, hydraulic cylinders, and electric cylinders.

[0029] In some implementations, please refer to Figure 6 As shown, the steel strip coating device also includes an assembly plate 5 and a spare atomizing nozzle 6. The atomizing nozzle 1 and the spare atomizing nozzle 6 are respectively detached and mounted on the assembly plate 5, which is connected to the transfer assembly 4. When the atomizing nozzle 1 fails and cannot be used normally, the coating line of the steel strip 8 can be immediately restored to operation by replacing the spare atomizing nozzle 6 on the assembly plate 5.

[0030] In some implementations, please refer to Figure 1 As shown, the steel strip adhesive application device also includes a vacuum cleaner 7, the air inlet of which is connected to the bottom of the cover 2 via a pipe. The vacuum cleaner 7 actively extracts the adhesive mist floating in the inner cavity of the cover 2, reducing the accumulation of adhesive mist in the cavity of the cover 2.
