[0002] A reel is an industrial device used for loading and unloading media such as gas, water, oil, lubricating oil, and cables. It is mainly used in hoisting machinery, construction machinery, and port and shipbuilding industries. Its drive types are spring-driven, electric, and pneumatic. Spring reels include both air hose reels and cable reels, while electric reels use a radial single-row winding or single-layer winding design. The structure is mostly made of hot-dip galvanized steel or polyester-coated materials, with a protection rating of IP65 / 66. The maximum cable capacity is 135 meters, and it is suitable for air pressure environments of 20-200 Bar. In modern industrial production, reels are important mechanical components and are widely used in lifting equipment, conveying systems, and other fields. The surface quality of the reel after casting directly affects its performance and lifespan. Therefore, grinding the surface of the cast reel is crucial.

[0011] A method for grinding machined surfaces used in roll casting, comprising the following steps:

[0012] S1: Place the drum on the surface of the second support plate. The ball bearings inside the second support plate can reduce the friction when the drum rotates. By activating the second electric telescopic rod inside the first fixed frame, its output end drives the third connecting plate to move, thereby realizing the lifting and lowering of the two sets of second support plates to adapt to drums of different sizes and complete the initial positioning of the drum.

[0013] S2: Turn on the second motor, and its output end drives the first connecting rod to rotate. The second connecting rods at both ends of the first connecting rod rotate accordingly. Since the two ends of the second connecting rod are rotatably connected to the moving plate, the moving plate is driven to slide symmetrically on the top of the support frame, thereby realizing the position adjustment of the grinding component in the transverse direction of the drum. After the third motor is turned on, it drives the second gear to rotate. The second gear meshes with the first gear, causing the first gear to rotate. When the sliding groove on the surface of the first gear rotates, it drives the first connecting plate to move through the sliding cooperation with the first connecting column, so that one side of the fixed block contacts the inner wall of the drum, thereby realizing the fixed clamping of drums of different sizes.

[0014] S3: Activate the first electric telescopic rod. The first electric telescopic rod moves the moving frame inside the second connecting plate until the bottom of the grinding disc contacts the outside of the drum, thereby adjusting the position and height of the grinding disc in the longitudinal direction of the drum. Start the first motor, whose output end drives the reciprocating screw to rotate. Since the outside of the reciprocating screw is threadedly connected to the second connecting plate, the second connecting plate moves back and forth inside the support frame. At the same time, the third gear and the fourth gear mesh. When the third gear rotates, it drives the rotating shaft and the fixed plate to rotate, thereby causing the drum to rotate on the second support plate. At this time, the drive motor inside the moving frame is activated, driving the grinding disc to rotate, so that the grinding disc can perform all-round grinding on the outside of the drum.

[0015] This invention provides a surface grinding device for roll casting. Compared with the prior art, it has the following advantages:

[0016] 1. This surface grinding device for roll casting achieves automated grinding of the roll surface through the collaborative work of multiple components. Compared with manual grinding, it greatly improves grinding efficiency. At the same time, the drive components such as the first motor and the second motor can quickly adjust the position of the grinding components, shorten the preparation time, and further improve the overall work efficiency.

[0017] 2. The surface grinding device for roll casting can adapt to the grinding needs of rolls of different specifications. The second electric telescopic rod can adjust the height of the second support plate to accommodate rolls of different heights. The movement of the moving plate and the second connecting plate, as well as the adjustment of the height of the moving frame by the first electric telescopic rod, enable the grinding disc to be adjusted in multiple dimensions, and can accurately grind the surface of rolls of various shapes and sizes.

The first motor 35 is started, and its output drives the reciprocating screw 23 to rotate. Since the outer side of the reciprocating screw 23 is threadedly connected to the second connecting plate 22, the second connecting plate 22 moves back and forth inside the support frame 2. Simultaneously, the third gear 42 meshes with the fourth gear 43. When the third gear 42 rotates, it drives the rotating shaft 7 and the fixed plate 8 to rotate, thereby causing the drum to rotate on the second support plate 34. At this time, the moving frame 3... The internal drive motor is turned on, which drives the grinding disc 16 to rotate, so that the grinding disc 16 can grind the outer side of the roll in all directions. During the grinding process, the dust suction ports 5 on both sides of the inner wall of the moving frame 3 are connected to the dust collection box 18 through the connecting pipe 4 and the hose 20. When the exhaust fan 17 is working, a negative pressure is formed in the dust collection box 18, which sucks the dust and impurities generated by grinding into the dust collection box 18 through the dust suction port 5, the connecting pipe 4 and the hose 20. The filter plate 19 inside the dust collection box 18 filters the incoming air to prevent dust and impurities from entering the exhaust fan 17, thus ensuring the normal operation of the equipment and the cleanliness of the working environment.

[0035] A method for grinding machined surfaces used in roll casting, comprising the following steps:

[0036] S1: Place the drum on the surface of the second support plate 34. The ball bearings inside the second support plate 34 can reduce the friction when the drum rotates. By activating the second electric telescopic rod 32 inside the first fixed frame 31, its output end drives the third connecting plate 33 to move, thereby realizing the lifting and lowering of the two sets of second support plates 34 to adapt to drums of different sizes and complete the initial positioning of the drum.

[0037] S2: Turn on the second motor 40, and its output end drives the first connecting rod 38 to rotate. The second connecting rod 39 at both ends of the first connecting rod 38 rotates accordingly. Since the two ends of the second connecting rod 39 are rotatably connected to the moving plate 6, the moving plate 6 is driven to slide symmetrically on the top of the support frame 2, thereby realizing the position adjustment of the grinding component in the transverse direction of the drum. After the third motor 15 is turned on, it drives the second gear 14 to rotate. The second gear 14 meshes with the first gear 11, causing the first gear 11 to rotate. When the sliding groove 12 on the surface of the first gear 11 rotates, it drives the first connecting plate 9 to move through the sliding cooperation with the first connecting column 13, so that one side of the fixed block 10 contacts the inner wall of the drum, thereby realizing the fixed clamping of drums of different sizes.

[0038] S3: Activate the first electric telescopic rod 21. The first electric telescopic rod 21 moves the moving frame 3 inside the second connecting plate 22 until the bottom of the grinding disc 16 contacts the outside of the drum, thereby realizing the position and height adjustment of the grinding disc 16 in the longitudinal direction of the drum. Start the first motor 35, and its output end drives the reciprocating screw 23 to rotate. Since the outside of the reciprocating screw 23 is threadedly connected to the second connecting plate 22, the second connecting plate 22 moves back and forth inside the support frame 2. At the same time, the third gear 42 meshes with the fourth gear 43. When the third gear 42 rotates, it drives the rotating shaft 7 and the fixed plate 8 to rotate, thereby causing the drum to rotate on the second support plate 34. At this time, the drive motor inside the moving frame 3 is activated, driving the grinding disc 16 to rotate, so that the grinding disc 16 can perform all-round grinding on the outside of the drum.

6. A method for grinding machined surfaces in roll casting, using the machined surface grinding apparatus for roll casting as described in claim 5, characterized in that, Includes the following steps: S1: Place the drum on the surface of the second support plate (34). The ball bearings inside the second support plate (34) can reduce the friction when the drum rotates. By activating the second electric telescopic rod (32) inside the first fixed frame (31), its output end drives the third connecting plate (33) to move, thereby realizing the lifting and lowering of the two sets of second support plates (34) to adapt to drums of different sizes and complete the initial positioning of the drum. S2: Turn on the second motor (40), and its output end drives the first connecting rod (38) to rotate. The second connecting rod (39) at both ends of the first connecting rod (38) rotates accordingly. Since the two ends of the second connecting rod (39) are rotatably connected to the moving plate (6), the moving plate (6) is driven to slide symmetrically on the top of the support frame (2), thereby realizing the position adjustment of the grinding component in the transverse direction of the drum. After the third motor (15) is turned on, it drives the second gear (14) to rotate. The second gear (14) meshes with the first gear (11), causing the first gear (11) to rotate. When the sliding groove (12) on the surface of the first gear (11) rotates, it drives the first connecting plate (9) to move through the sliding cooperation with the first connecting column (13), so that one side of the fixed block (10) contacts the inner wall of the drum, thereby realizing the fixed clamping of drums of different sizes. S3: Activate the first electric telescopic rod (21). The first electric telescopic rod (21) moves the moving frame (3) inside the second connecting plate (22) until the bottom of the grinding disc (16) contacts the outside of the drum, thereby realizing the position adjustment and height adjustment of the grinding disc (16) in the longitudinal direction of the drum. Start the first motor (35), and its output end drives the reciprocating screw (23) to rotate. Since the outside of the reciprocating screw (23) is threadedly connected to the second connecting plate (22), the second connecting plate (22) moves back and forth inside the support frame (2). At the same time, the third gear (42) meshes with the fourth gear (43). When the third gear (42) rotates, it drives the rotating shaft (7) and the fixed plate (8) to rotate, thereby making the drum rotate on the second support plate (34). At this time, the drive motor inside the moving frame (3) is activated, driving the grinding disc (16) to rotate, so that the grinding disc (16) can perform all-round grinding on the outside of the drum.
