Description

Technical Field

[0001] The utility model relates to the technical field of roller production, in particular to a surface spraying device for a cast iron roller. Background Art

[0002] The roller includes a main body end and a rotating shaft end. During the spraying process, the surface of the main body end needs to be sprayed continuously to improve the rolling performance of the surface of the main body end.

[0003] During the spraying process, especially the cold spraying process, in order to prevent the sprayed paint from drifting to the surface of the shaft end and affecting the subsequent installation accuracy and rotation smoothness of the shaft end, it is necessary to install a protective device on the outside of the shaft end; some companies wrap a protective film around the surface of the shaft end, and some companies customize a special cylindrical sealing sleeve to seal the surface of the shaft end.

[0004] In the actual production process, the operation of winding film is cumbersome, and each spray needs to be wrapped separately. The sealing effect is subject to the tightness of the film winding and the winding area. Although the sealing sleeve can be reused, it needs to be customized according to different shaft ends, which increases the cost. At the same time, the cylindrical sealing sleeve needs to be installed before the roller is placed, which increases the difficulty of the spraying staff. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.

[0022] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0023] See attached Figure 1 -Attached Figure 4 A cast iron roller surface spraying device includes a carrier 100 that carries a roller 200 and controls the rotation of the roller 200, and a spraying assembly located outside the carrier 100. During the process of controlling the rotation of the roller 200 by the carrier 100, the surface of the main body end 210 of the roller 200 is continuously sprayed by the spraying assembly to improve the mechanical properties of the surface of the roller 200 and enhance the effect and quality of subsequent rolling.

[0024] The rolling roller 200 includes a main body end 210 and a rotating shaft end 220. During the spraying process, only the surface of the main body end 210 needs to be continuously sprayed to improve the rolling performance of the surface of the main body end 210; during the spraying process, especially the cold spraying process, in order to prevent the sprayed paint from drifting to the surface of the rotating shaft end 220 and to avoid affecting the subsequent installation accuracy and rotation smoothness of the rotating shaft end 220, a protective device needs to be installed on the outside of the rotating shaft end 220; some companies wrap a protective film around the surface of the rotating shaft end 220, and some companies customize a special cylindrical sealing sleeve to seal and protect the surface of the rotating shaft end 220.

[0025] However, the operation of wrapping the film is complicated, and each spray needs to be wrapped separately. The sealing effect is subject to the tightness of the film wrapping and the wrapping area. Although the sealing sleeve can be reused, it needs to be customized according to the different shaft ends 220, which increases the cost. At the same time, the cylindrical sealing sleeve needs to be installed before the roller 200 is placed, which increases the difficulty of the spraying staff.

[0026] In order to solve the above problems, a sealing device 300 is installed on the inner side wall of the carrying device 100, and the sealing device 300 includes two sealing mounting frames 320. The first end of the sealing mounting frame 320 is rotatably connected to the inner side wall of the carrying device 100 through a rotation limiting element 330, and an arc-shaped sealing component 310 is fixed to the second end of the sealing mounting frame 320. A deflection control component 500 is installed on the inner side wall of the carrying device 100. The two sealing components 310 are driven to engage with each other through the deflection control component 500 to complete the sealing of the rotating shaft end 220 of the roller 200.

[0027] During the spraying process, the roller 200 is first placed on the surface of the carrier 100 so that the shaft end 220 of the roller 200 is located on the upper end surface of the carrier 100; after the roller 200 is placed, the two sealing components 310 are controlled to deflect from both sides toward the middle to complete the engagement. After the two sealing components 310 are engaged, they can be sleeved on the outside of the shaft end 220 to seal and protect the shaft end 220 from the outside to prevent the sprayed material from adhering to the surface of the shaft end 220, while ensuring the complete and uniform spraying of the surface of the main body end 210 and the cleanliness of the surface of the shaft end 220, which is convenient for the subsequent installation and commissioning of the roller 200 and shortens the time and process of subsequent processing.

[0028] Specifically, the sealing assembly 310 includes a sealing cover 312 fixedly connected to a sealing mounting frame 320, and an arc-shaped sealing block 311 is rotatably connected to the outer side of the sealing cover 312. The two sealing blocks 311 are detachably connected to form a sealing ring. The cross-section of the sealing cover 312 and the sealing block 311 after biting is circular. The axis of the sealing assembly 310 is consistent with the axis of the roller 200. The sealing assembly 310 is integrally sleeved on the outer side of the rotating shaft end 220 of the roller 200, which can achieve efficient sealing. At the same time, the sealing block 311 here can be tightly pressed against the end face of the roller 200 and can rotate synchronously with the roller 200, which reduces the wear between the roller 200 and the sealing device 300 and can further enhance the sealing effect between the roller 200 and the sealing device 300.

[0029] A T-shaped engagement groove is provided on the side wall of the sealing block 311, and a T-shaped engagement block is fixed on the outside of the sealing cover 312. The T-shaped engagement design can prevent the sealing block 311 from detaching from the sealing cover 312 during rotation, thereby ensuring the stability and air tightness of the sealing block 311 during rotation.

[0030] Furthermore, the side wall of the sealing component 310 is connected to a pumping device via a high-pressure connector 400. Specifically, the high-pressure connector 400 is fixedly connected to the sealing cover 312. The pumping device can continuously pump gas into the sealing component 310 through the high-pressure connector 400, thereby forming a high-pressure area inside the sealing component 310, further preventing the sprayed paint from entering the surface of the shaft end 220.

[0031] The outer side of the sealing cover 312 can be designed to be contracted, or an annular elastic airbag can be designed. The elastic airbag design can narrow the open area on the outside, reduce the rate of high-pressure gas overflow in the sealing component 310, and maintain the state of the high-pressure area in the sealing component 310.

[0032] Furthermore, the rotation limit element 330 includes a limit shaft 331, and the outer side of the limit shaft 331 is rotatably connected to a limit sleeve 332 fixed to the sealing mounting frame 320, and a length adjustment element 333 is arranged between the limit sleeve 332 and the supporting device 100. The length adjustment element 333 can be used to adjust the position between the limit sleeve 332 and the supporting base 110, thereby changing the distance between the upper sealing component 310 and the main body end 210, thereby realizing adaptive sealing for main body ends 210 of different sizes, and meeting the requirements of spraying processing; at the same time, the length adjustment element 333 here can select an adjustment element with elastic pre-tightening force, which can make the sealing component 310 and the end face of the main body end 210 tightly pressed, thereby ensuring the stability of the sealing state of the sealing component 310.

[0033] Specifically, the carrying device 100 includes a carrying base 110 and a carrying roller 120 installed on the upper end of the carrying base 110. The carrying roller 120 is designed as two groups. By controlling the rotation of the carrying roller 120, the upper roller 200 can be driven to rotate. When the position of the spraying component is determined, continuous spraying of the surface of the main body end 210 is achieved.

[0034] Specifically, as a preferred control method, the deflection control assembly 500 here includes a double-headed telescopic rod, and the telescopic end of the double-headed telescopic rod is connected to the corresponding sealing mounting frame 320 through a connecting workpiece. In the process of controlling the double-headed telescopic rod, the sealing mounting frames 320 on both sides can be controlled to open at a predetermined angle; the two sealing mounting frames 320 and the sealing assembly 310 are opened at a predetermined angle to facilitate the loading and unloading of the roller 200; the two sealing mounting frames 320 are controlled to be close, and the sealing assembly 310 can be combined to form an annular sealing area to seal and protect the rotating shaft end 220, thereby ensuring that the spraying is carried out comprehensively and efficiently.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
