Description

Technical Field

[0001] This utility model relates to the field of rubber roller processing technology, and in particular to a milling device for producing polyurethane rubber rollers. Background Technology

[0002] Milling is a common method of cold working metal. Unlike turning, in milling, the cutting tool rotates at a low speed driven by the spindle, while the workpiece is relatively stationary. Milling is often used in the production of polyurethane rollers.

[0003] Existing milling equipment generally relies on manual loading, but the weight of the rubber rollers can often reach tens or even hundreds of kilograms. Relying on manual handling for loading is not only labor-intensive, but also poses safety hazards, easily causing muscle injuries to personnel or damage to workpieces from falling. Manual placement is prone to skewness, requiring repeated adjustments and prolonging auxiliary time. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies by proposing a milling device for the production of polyurethane rollers, which can reduce the difficulty of loading and unloading materials and improve processing efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A milling device for producing polyurethane rubber rollers includes a support plate, a rotating shaft rotatably connected to the middle of the support plate, rotating plates fixedly connected to both ends of the rotating shaft, a toothed ring fixedly connected to the lower outer side of the rotating plate, a fixing assembly for mounting the rubber rollers provided at the upper end of the rotating plate, support plates fixedly connected to the lower sides of both ends of the support plate, a toothed plate movable back and forth provided on the upper side of the support plate, the upper side of the toothed plate meshing with the outer side of the toothed ring, an opening provided at the upper end of the support plate, a connecting plate movable back and forth provided on the inner side of the opening, the left and right ends of the connecting plate fixedly connected to opposite sides of the toothed plate, a support plate fixedly connected to opposite sides of the lower end of the support plate, an electric push rod fixedly connected to the upper side of the support plate, the driving end of the electric push rod fixedly connected to the lower side of the connecting plate, a feeding assembly for placing the rubber rollers provided at the front end of the support plate, and a milling assembly mounted on the upper side of the support plate.

[0007] Furthermore, the fixing assembly includes a fixed shaft rotatably connected to the upper end of a rotating plate at the right end of the rotating shaft, a first turntable fixedly connected to the end of the fixed shaft, a motor fixedly connected to the upper right side of the rotating plate, and the drive end of the motor fixedly connected to the middle of the right end of the fixed shaft.

[0008] Furthermore, the fixing assembly also includes a first hydraulic rod fixedly connected to the upper end of the rotating plate at the left end of the rotating shaft. The driving end of the first hydraulic rod is fixedly connected to a connecting plate. A movable rod is fixedly connected to the left side of the connecting plate. The left end of the movable rod passes through the upper end of the rotating plate. A second turntable is rotatably connected to the right side of the connecting plate.

[0009] Furthermore, the milling assembly includes a gantry fixedly connected to the upper side of a support plate, an electric slide rail fixedly connected to the upper end of the gantry, a second hydraulic rod fixedly connected to the output end of the electric slide rail, a mounting plate fixedly connected to the output end of the second hydraulic rod, and a milling head fixedly connected to the lower side of the mounting plate.

[0010] Furthermore, reinforcing bolts are installed at both ends of the gantry frame, with the opposite ends of the reinforcing bolts respectively inserted inside the rotating plate.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the electric push rod can drive the toothed plate to move backward through the connecting plate, thereby driving the rotating plate to rotate forward through the cooperation of the toothed plate and the toothed ring. This causes the first and second turntables on the rotating plate to move to the two ends of the rubber roller placed on the pad. Then, the first hydraulic rod drives the second turntable to approach the rubber roller and fix it between the second turntable and the first turntable. Subsequently, it rotates in the opposite direction to move the rubber roller to the processing area, thereby solving the problem that the rubber roller is too heavy and inconvenient for loading and unloading.

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.

[0025] Reference Figures 2-4This utility model provides an embodiment of a milling device for producing polyurethane rollers, comprising a bearing plate 1, a rotating shaft 2 rotatably connected to the middle of the bearing plate 1, rotating plates 3 fixedly connected to both ends of the rotating shaft 2, a toothed ring 4 fixedly connected to the lower outer side of the rotating plate 3, support plates 5 fixedly connected to the lower sides of both ends of the bearing plate 1, a toothed plate 6 movable back and forth provided on the upper side of the support plate 5, the upper side of the toothed plate 6 meshing with the outer side of the toothed ring 4, an opening 7 opened at the upper end of the support plate 5, a connecting plate 8 movable back and forth provided on the inner side of the opening 7, the left and right ends of the connecting plate 8 respectively fixedly connected to the opposite side of the toothed plate 6, a support plate 9 fixedly connected to the opposite side of the lower end of the support plate 5, an electric push rod 10 fixedly connected to the upper side of the support plate 9, and the driving end of the electric push rod 10 fixedly connected to... Connected to the lower side of the connecting plate 8, the upper end of the rotating plate 3 at the right end of the rotating shaft 2 is rotatably connected to a fixed shaft 11. The end of the fixed shaft 11 is fixedly connected to a first turntable 12. The upper right side of the rotating plate 3 is fixedly connected to a motor 13. The drive end of the motor 13 is fixedly connected to the middle of the right end of the fixed shaft 11. The upper end of the rotating plate 3 at the left end of the rotating shaft 2 is fixedly connected to a first hydraulic rod 14. The drive end of the first hydraulic rod 14 is fixedly connected to a connecting plate 15. The left side of the connecting plate 15 is fixedly connected to a movable rod 17. The left end of the movable rod 17 passes through the upper end of the rotating plate 3. The right side of the connecting plate 15 is rotatably connected to a second turntable 16. The front end of the bearing plate 1 is fixedly connected to a limit rod 24. The outside of the limit rod 24 is provided with a pull-out plate 25 that moves back and forth. The upper side of the pull-out plate 25 is fixedly connected to a pad 26 for placing rubber rollers.

[0026] The rubber roller to be processed is placed horizontally on the pad 26. The pull plate 25 is pushed manually or with auxiliary equipment, causing the pad 26 to move the rubber roller back and forth along the limiting rod 24. The position of the clamping roller is adjusted to ensure that the vertical distance between its central axis and the rotating shaft 2 is equal to the vertical distance between the central axis of the second turntable 16 and the rotating shaft 2, facilitating subsequent alignment. The upper side of the pad 26 has an arc-shaped concave surface to improve the stability of the rubber roller placement. The electric push rod 10 is activated, pushing the connecting plate 8 backward, causing the toothed plates 6 on both sides to move backward synchronously. The toothed plate 6 meshes with the toothed ring 4, driving the rotating plate 3 to flip forward, so that the first turntable 12 and the second turntable 16 approach the end face of the rubber roller from both sides. The first hydraulic rod 14 pushes the connecting plate 15 to move to the left, so that the second turntable 16 is in close contact with the left end of the rubber roller, and pushes the other end of the rubber roller to contact the first turntable 12 to clamp the rubber roller. The rotating plate 3 rotates in the opposite direction to lift the clamped rubber roller to the processing height. The loading and unloading of the rubber roller is realized by the flipping of the rotating plate 3, which reduces the difficulty of loading and unloading and improves the processing efficiency.

[0027] Reference Figure 1 , Figure 5 and Figure 6A gantry 18 is fixedly connected to the upper side of the support plate 5. An electric slide rail 19 is fixedly connected to the upper end of the gantry 18. A second hydraulic rod 20 is fixedly connected to the output end of the electric slide rail 19. A mounting plate 21 is fixedly connected to the output end of the second hydraulic rod 20. A milling head 22 is fixedly connected to the lower side of the mounting plate 21. Reinforcing bolts 23 are provided at both ends of the gantry 18. The opposite ends of the reinforcing bolts 23 are respectively inserted into the interior of the rotating plate 3. A protective cover 27 is fixedly connected to the upper rear end of the bearing plate 1. A collection box 28 is movably arranged on the inner side of the lower end of the protective cover 27.

[0028] Insert the reinforcing bolts 23 into the corresponding holes of the gantry frame 18 and the rotating plate 3 to lock the position of the rotating plate and prevent vibration or displacement during milling; start the motor 13 to drive the first turntable 12 to rotate, and the rubber roller moves accordingly. The second hydraulic rod 20 drives the milling head 22 to move down and contact the surface of the rubber roller; at the same time, the electric slide rail 19 controls the milling head 22 to move left and right along the axis of the rubber roller to complete the milling of the entire roller surface. The polyurethane debris generated during milling is splashed backward by centrifugal force, blocked by the protective cover 27 and falls into the collection box 28 below, realizing clean production.

[0029] Working principle: When milling the rubber roller, the rubber roller to be processed is placed on the pad 26. The pull plate 25 drives the pad 26 and the rubber roller to move back and forth to adjust the position of the rubber roller. Then, the electric push rod 10 is activated to push the connecting plate 8 to move backward, thereby driving the toothed plate 6 to move backward. The toothed plate 6 and the toothed ring 4 cooperate to drive the rotating plate 3 to rotate forward, so that the second turntable 16 and the first turntable 12 move the left and right ends of the rubber roller placed on the pad 26. Then, the first hydraulic rod 14 drives the connecting plate 15 to move towards the rubber roller, so that the second turntable 16 and the first turntable 12 clamp the rubber roller in the middle. Then the rotating plate 3. Reverse rotation drives the rubber roller to the processing area. Then, the reinforcing bolt 23 passes through the holes set on the gantry 18 and the rotating plate 3 to improve the stability of the rotating plate 3 during the processing. The motor 13 is started to drive the first turntable 12 to rotate, thereby driving the rubber roller to rotate. The second hydraulic rod 20 is started to drive the milling head 22 to descend and contact the rubber roller. As the rubber roller rotates, the milling head 22 moves left and right through the electric slide rail 19 to complete the milling operation of the rubber roller. The milling debris splashes to the rear of the device and is collected in the collection box 28 by the blocking of the protective cover 27 for easy subsequent cleaning.
