[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] The purpose of this invention is to provide a cold rolling mill plate blowing device to solve the problems existing in the prior art. It has a simple structure, is easy to use, and effectively ensures the blowing effect of the steel plate.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] This utility model provides a cold rolling mill plate surface cleaning device, such as... Figure 1As shown, the device includes: a walking mechanism, a crossbar, multiple sliding seats, a driving component, and multiple air ducts. The walking mechanism can move on the ground and maintain its position after movement. The crossbar is horizontally set and fixedly connected to the top of the walking mechanism and can span the steel plate across its width. The sliding seats are slidably connected to the bottom of the crossbar. The fixed end of the driving component is fixedly connected to the crossbar, and the driving end of the driving component is used to drive each sliding seat to move along the length of the crossbar and maintain its position after movement. One air duct is installed at the bottom of one of the sliding seats, and one end of the air duct is used to communicate with an air source device. The bottom of the air duct is provided with multiple air outlets. The walking mechanism has the functions of moving on the ground and positioning, enabling this purging device to have good mobility and positioning stability in the complex environment of the cold rolling mill workshop. Operators can easily move the device next to the cold-rolled steel plate to be purged, ensuring it precisely stops at the designated working position, providing stable foundation support for the purging operation. A crossbar spans the top of the traveling mechanism, ensuring the device can cover cold-rolled steel plates of varying widths, meeting the production needs of various specifications and effectively expanding its applicability. This significantly improves the device's versatility and compatibility, reducing purging dead zones caused by differences in steel plate width. The sliding connection design between the sliding seat and the crossbar allows the sliding seat to move flexibly along the length of the crossbar, providing flexible possibilities for adjusting the position of the air guide pipe. By changing the position of the sliding seat, operators can adjust the air guide pipe to the designated purging position, enhancing the device's adaptability and targeting for purging different areas of the steel plate, thereby improving purging efficiency and quality. The drive component is securely connected to the crossbar via a fixed end, precisely driving the sliding seat to move and position along the length of the crossbar. This driving method not only provides stable and reliable power output, ensuring the smooth movement of the sliding seat, but also allows operators to accurately control the position of the sliding seat according to the actual purging needs of the steel plate, thereby adjusting the position of the air guide pipe and achieving precise and efficient purging operations on specific locations of the steel plate.

[0024] Each sliding seat has an air duct installed at its bottom, which is connected to the air source device. Multiple air outlets are located at the bottom, ensuring that each duct can deliver air independently and precisely. These multiple outlets allow compressed air to be evenly ejected from the bottom of the duct, acting on the steel plate surface from multiple angles and over a large area. This significantly improves the coverage and uniformity of cleaning impurities on the steel plate surface, effectively removing various debris and ensuring that the steel plate surface cleanliness meets production standards.

[0025] In a preferred embodiment, the driving component includes a first connecting plate, a second connecting plate, and a lead screw. The tops of the first connecting plate and the second connecting plate are fixedly connected to the crossbar. The two ends of the lead screw are rotatably connected to the first connecting plate and the second connecting plate, respectively. The sliding seat is provided with a threaded hole and is disposed between the first connecting plate and the second connecting plate. The lead screw passes through the threaded hole and is threadedly connected to the sliding seat. Rotating the lead screw allows the sliding seat to slide along the length of the crossbar. The lead screw drive method has a simple and stable structure. The movement of the sliding seat can be precisely controlled by rotating the lead screw. It is convenient to operate and has accurate positioning, which helps to improve the accuracy of the air duct position adjustment, thereby improving the accuracy of purging.

[0026] In a preferred embodiment, the cold rolling mill plate blowing device further includes a rotating handle, which is fixedly connected to one end of the lead screw extending out of the second connecting plate. The rotating handle provides a convenient point of force for manual operation of the lead screw, making it easy for the operator to rotate the lead screw and adjust the position of the sliding seat, thereby improving the convenience and flexibility of operation.

[0027] In a preferred embodiment, the cold rolling mill plate blowing device further includes a guide rod disposed below the lead screw, with both ends of the guide rod fixedly connected to the first connecting plate and the second connecting plate, respectively. The sliding seat has a through hole, through which the guide rod passes to guide the sliding direction of the sliding seat. The guide rod provides precise guidance for the sliding of the sliding seat. Since both ends of the guide rod are fixedly connected to the first and second connecting plates and pass through the through hole of the sliding seat, when the lead screw rotates to drive the sliding seat to move, the guide rod effectively restricts the sliding seat to only move in a straight line along the direction of the guide rod, preventing irregular movements such as offset, swaying, or rotation during movement. This not only ensures the smoothness and straightness of the sliding seat's movement, thereby improving the accuracy of the air duct position adjustment, but also enhances the stability of the sliding seat during movement, making the entire blowing device more reliable and precise when adjusting the air outlet position, further improving the blowing effect and the device's service life.

[0028] In a preferred embodiment, the cold rolling mill plate blowing device further includes multiple connecting columns. The top end of the connecting column is fixedly connected to the sliding seat, and the bottom end of the connecting column is fixedly connected to the air guide pipe. The connection columns ensure a stable connection between the sliding seat and the air guide pipe, so that when the sliding seat moves, the air guide pipe can be reliably driven to move synchronously, thus ensuring the stability of the device structure and the coordination of the overall operation.

[0029] In a preferred embodiment, the cold rolling mill plate blowing device further includes a first telescopic component and a second telescopic component. Both the first and second telescopic components are vertically arranged. The fixed end of the first telescopic component is fixedly connected to the crossbar, and the telescopic end of the first telescopic component is fixedly connected to the first connecting plate. The fixed end of the second telescopic component is fixedly connected to the crossbar, and the telescopic end of the second telescopic frame is fixedly connected to the second connecting plate. The first and second telescopic components extend and retract synchronously. Both the first and second telescopic components are electrically operated telescopic rods, which, acting as the first and second telescopic components, allow for synchronous adjustment of the height of the driving component. This enables adjustment of the distance between the air guide pipe and the steel plate surface to optimize the blowing effect under different blowing requirements, such as different thicknesses of steel plates or different blowing conditions, increasing the adaptability and adjustability of the device.

[0030] In a preferred embodiment, the walking mechanism includes a first support leg and a second support leg. The two ends of the crossbar are fixedly connected to the tops of the first support leg and the second support leg, respectively. The structure of the first support leg and the second support leg provides stable support for the crossbar, thereby ensuring the structural stability of the entire device and ensuring that the device will not shake or tip over during the purging operation, thus ensuring the normal operation of the purging work.

[0031] In a preferred embodiment, the cold rolling mill plate cleaning device further includes a plurality of first casters and a plurality of second casters. Each first caster is disposed at the bottom of the first support leg, and each second caster is disposed at the bottom of the second support leg. The casters enable the traveling mechanism to flexibly change its traveling direction, facilitating the device to quickly move to different positions in complex workshop environments to perform cleaning operations on the cold rolling mill, thereby improving the device's mobility.

[0032] In a preferred embodiment, the cold rolling mill plate blowing device further includes a first locking member and a second locking member. The first locking member is disposed at the bottom of the first support leg to lock the first caster wheel after it moves to the target position. The second locking member is disposed at the bottom of the second support leg to lock the second caster wheel after it moves to the target position. The locking members can lock the caster wheel after the device moves to the required position, preventing unnecessary movement of the device due to external interference or other reasons during the blowing process, ensuring the positional stability of the device during operation, and ensuring the accuracy of the blowing operation.

[0033] In a preferred embodiment, both the first support leg and the second support leg are electrically telescopic rods. As support legs, the electrically telescopic rods can adjust the overall height of the device according to actual needs to adapt to cold rolling mill equipment of different heights or different purging operation requirements, further improving the versatility and practicality of the device.
