Description

Technical Field

[0001] This utility model relates to the field of outer membrane of anti-collision pillars, specifically to a device for cutting the warning outer membrane of anti-collision pillars. Background Technology

[0002] As a key physical barrier in the traffic safety system, road crash barriers require warning stickers to cover the road surface sections above them to alert pedestrians and drivers. Traditional installation methods for these warning stickers present several problems: First, the warning film needs to be cut from rolls, currently relying mainly on manual labor, which is inefficient and makes it difficult to guarantee cutting accuracy. Second, due to the lack of specialized cutting equipment, operators cannot ensure a perfect fit between the cut film and the barrier surface. Third, existing methods cannot precisely adjust the width of the warning film needed for barriers of different diameters. These problems result in inconsistent installation quality, affecting both aesthetics and warning effectiveness, and may even shorten the lifespan of the warning stickers due to poor adhesion. Utility Model Content

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0015] like Figure 1-2 As shown, this application proposes a device for cutting the outer film of a warning post, including a support frame and a warning film roll that is rotatably supported on its upper part. The warning film of the warning film roll passes around the guide roller and is flush with the support rod on one side of the support frame. The support rod slidably supports a support plate located below the warning film and adjusts its cutting width.

[0016] The support frame can be welded from metal profiles, and its structural strength meets the support requirements. The warning film roll is rotated and supported by bearings or bushings, facilitating continuous conveying of the warning film. The guide rollers are preferably smooth metal rollers or rubber-coated rollers to ensure flat conveying of the warning film. The support rods can be square rods, and they are welded to the support frame. The support plate can be made of sheet metal, and its sliding connection with the support rod can be achieved through a guide rail slider mechanism or a dovetail groove structure, facilitating adjustment of the cutting width.

[0017] This device provides overall support via a support frame, continuously supplies warning film rolls, ensures the flatness of the film transport by guide rollers, and allows for adjustable cutting width through the cooperation of support rods and support plates. Compared to manual cutting methods in existing technologies, this device enables mechanized cutting of warning film, improving cutting efficiency and ensuring neatness of the cut edges, thus solving the problems of low efficiency and poor results associated with manual cutting. The width adjustment function of the support plate can accommodate the cutting needs of warning film for different sizes of anti-collision posts.

[0018] Furthermore, this application also proposes that sliding frames are provided on both sides of the front end of the support plate, the lower part of the sliding frame is connected and fixed to the slider in the sliding groove on both sides of the support frame, and the rear end of the support plate is slidably connected to the through hole in the center of the support rod.

[0019] The sliding frame is made of metal and is integrally connected to the front sides of the support plate. Slides are formed on the uprights on both sides of the support frame, with a T-shaped or dovetail-shaped cross-section. The slider is made of nylon and is fixed to the lower part of the sliding frame with screws. The through hole is a strip-shaped through hole, slightly larger than the support plate size; a copper sleeve can be installed inside the hole to reduce frictional resistance. Locking screws can be wing screws or hex socket screws, with rubber washers at the threaded ends to prevent scratching the slide surface.

[0020] Specifically, this technical solution achieves lateral position adjustment of the support plate through the cooperation of a sliding frame and a sliding groove, while maintaining the relative positional relationship between the support plate and the support rod using through holes. When it is necessary to adjust the cutting width of the warning film sticker, loosen the locking screw and push the sliding frame forward or backward along the sliding groove, and the support plate slides synchronously on the support rod through the through holes. After adjustment, tighten the locking screw to fix the position of the support plate. The cooperation structure of the sliding groove and the slider effectively prevents the support plate from shifting during the cutting process, while the through holes ensure the stability of the support plate during movement. Compared with manual cutting, this device can achieve precise adjustment of the cutting width, and the adjustment process is simple and reliable, avoiding cutting errors caused by manual operation.

[0021] Furthermore, this application also proposes that the upper part of the slide groove be provided with scale lines for measuring the width of the warning film sticker, and that the upper part of the slide frame be provided with locking screws.

[0022] Specifically, the scale lines can be printed or engraved on the upper surface of the slide groove, using millimeters or centimeters as the unit of measurement, allowing operators to intuitively read the cut width of the warning film. The locking screws on the slide frame can be wing nuts or hex socket screws, securing the slide frame via a threaded connection. As a preferred embodiment, a rubber gasket can be placed at the end of the locking screw to prevent direct pressure on the slide frame and subsequent deformation. The scale lines can be positioned parallel to the length of the slide groove, corresponding to the movement trajectory of the slider.

[0023] Therefore, by using the scale lines and locking screws, operators can precisely adjust and fix the position of the sliding frame, thereby accurately controlling the cutting width of the warning film. This solution solves the problem of inconsistent width during manual cutting and avoids the tedious operation of repeated measurement and adjustment. Compared with existing technologies, this structure significantly improves cutting accuracy and operational efficiency while maintaining the simplicity of the device, and the adjustment process has the advantages of visualization and repeatability.

[0024] Furthermore, this application also proposes that the warning film roll is rotatably sleeved on the rotating shaft, and the rotating shaft is supported in the slots on both sides of the support frame.

[0025] Specifically, the rotating shaft is a cylindrical metal rod with a diameter slightly smaller than the central hole of the warning film roll to allow for free rotation. The slot has a U-shaped opening structure and is located at the top of the two side uprights of the support frame, with the opening facing upwards for easy loading and unloading of the rotating shaft. As a preferred embodiment, annular limiting flanges can be provided at both ends of the rotating shaft to prevent axial movement of the rotating shaft within the slot. Furthermore, the inner wall of the slot can be lined with a wear-resistant material layer to reduce frictional resistance.

[0026] Therefore, this technical solution achieves stable rotational support for the warning film roll through the cooperation of the rotating shaft and the slot. The rotating shaft directly bears the weight of the warning film roll and transfers it to the support frame, while the slot structure ensures both the positioning accuracy of the rotating shaft and facilitates maintenance and replacement. Compared to manual hand-held cutting, this structure ensures that the warning film remains flat during transport, avoiding cutting deviations caused by vibration. Specifically, the rotating support structure allows the warning film roll to automatically release the film material based on traction force, eliminating the need for manual intervention to adjust its position, thereby improving cutting efficiency and quality stability.

[0027] Furthermore, this application also proposes that the guide roller is disposed at the lower part of the warning film roll and is rotatably connected to the support frame, with the bottom of the guide roller being flush with the top of the support plate.

[0028] The guide roller can be made of metal or engineering plastic, and its surface can be textured with anti-slip patterns to increase friction with the warning film. The rotary connection can be achieved using bearings or bushings, with deep groove ball bearings or sliding bearings being suitable options. The diameter of the guide roller can range from 50-100mm, with the specific dimensions adjusted according to the width of the warning film roll. The guide roller is positioned flush with the support plate to ensure it is level above the support plate for easy cutting.

[0029] This technical solution maintains the flatness of the warning film during transport by placing guide rollers at the bottom of the warning film roll and rotating them with the support frame, preventing wrinkles or shifting. The design of the bottom of the guide rollers being flush with the top of the support plate ensures the stability of the warning film during cutting, resulting in cleaner cut edges. Compared to existing manual cutting methods, this solution achieves automatic transport and accurate positioning of the warning film, improving cutting precision and efficiency. Specifically, the rotating guide rollers reduce film transport resistance, while the flush setting ensures accurate cutting position, thus solving the technical problems of low efficiency and inconsistent quality associated with manual cutting.

[0030] The implementation principle of the anti-collision pillar warning outer membrane cutting device in this application embodiment is as follows:

[0031] Place the warning film roll 4 on the rotating shaft 3 and snap it into the slot 2 of the support frame 1. Pull out the end of the warning film sticker 41 wrapped with the warning film roll 4, pass it around the guide roller 5, and place it on the upper part of the support plate 6 and finally stick it to the support rod 9.

[0032] Calculate the required width of the warning film based on the diameter of the crash barrier post. After calculation, loosen the locking screws and adjust the slider on the side of the sliding bracket 7 to slide within the slide groove 101. This adjusts the distance between the front end of the support plate 6 and the support rod 9, which is the required width of the warning film. After adjustment, press down the warning film 41 on the support plate 6 with your hand, and then use scissors to cut horizontally along the front sliding bracket 7 of the support plate 6 to achieve the required cut of the warning film.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
