However, when using the above support device to process the roller end, the roller end is subject to certain limitations, which can easily affect the processing operation of the roller end. Therefore, this utility model is proposed. Utility Model Content

[0014] 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.

[0015] During the processing of the end of the roller, a support device is required. The support device provided by this utility model is specifically used to provide support and fixation for the bottom, side and top of the roller body, exposing the end of the roller body to facilitate the processing operation of the end of the roller body. Before using this device, it is necessary to carry out preparatory work such as inspection to ensure the normal use of the device.

[0016] like Figures 1-5 As shown, this utility model provides a technical solution: a novel roller support device, including a base block 1, with limit posts 101 fixed at the four corners of the top surface of the base block 1, and a lifting arch plate 102 slidably arranged on the outer side of the limit posts 101. A clamping support assembly is provided on the lifting arch plate 102, and the clamping support assembly includes a U-shaped lifting plate 105 fixed on the lifting arch plate 102. A first bidirectional screw rod 2 is rotatably inserted on one side of the U-shaped lifting plate 105 relative to the vertical plate, and a first fixed rod is fixedly inserted on the other side. The first bidirectional screw rod 2 is horizontally arranged. A limit plate 207 is symmetrically slidably sleeved on the middle of the first bidirectional screw rod 2 and the first fixed rod. The limit plate 207 is fixed to the U-shaped lifting plate 105. A U-shaped mounting plate 103 is fixed in the middle of the bottom surface of the lifting arch plate 102. Worms 3 are rotatably inserted on both the front and back sides of the U-shaped lifting plate 105. The two worms 3 are horizontally staggered, and worm wheels 301 are meshed on the outer side of each worm 3.

[0017] In this embodiment, the worm gear 3 rotates through the U-shaped mounting plate 103 and the lifting arch plate 102. The bottom end of the worm gear 3 located on the front side is connected to a rotating motor, which is mounted on the bottom surface of the U-shaped mounting plate 103. The central shaft of the worm wheel 301 is fixed with insert rods, and the two ends of the insert rods are rotatably fitted with U-blocks fixed on the U-shaped lifting plate 105. The top end of the worm wheel 301 is fixed with a vertical tube 302, and an inverted L-shaped pressure rod 303 is slidably inserted into the upper part of the vertical tube 302. The bottom surface of the crossbar of the inverted L-shaped pressure rod 303 is fixed with a top elastic pad. A telescopic rod 304 is connected between the bottom end of the inverted L-shaped pressure rod 303 and the vertical tube 302. A synchronous belt 305 is connected between the lower parts of the two worm gears 3. The synchronous belt 305 is located above the U-shaped mounting plate 103. The worm gear 3, the synchronous belt 305, and the worm wheel 301 are existing technologies. The synchronous belt 305 ensures that the two worm gears 3 rotate in the same direction, thereby causing the two worm wheels 301 to rotate in opposite directions.

[0018] In this embodiment, the first bidirectional lead screw 2 and the first fixed rod are symmetrically fitted with sliding sleeves 201 at both ends. A U-shaped support plate 202 is fixed to the top of the sliding sleeve 201. A bottom elastic pad is fixed to the middle of the top surface of the U-shaped support plate 202. End plates 203 are symmetrically fixed to the bottom end of the U-shaped support plate 202. A second bidirectional lead screw 204 is rotatably inserted between one end of the two end plates 203 on the bottom surface of the U-shaped support plate 202, and a second fixed rod is fixedly inserted on the other end. The second bidirectional lead screw 204 is horizontally and vertically arranged. U-shaped sleeves 201 are fitted to both ends of the second bidirectional lead screw 204 and the second fixed rod. 5. The U-shaped support plate 202 has sliding holes that fit the U-shaped sleeve plate 205. The top of the U-shaped sleeve plate 205 is fixed with a clamping vertical plate 206. The clamping vertical plate 206 is fixed with side elastic pads on its inner side. One end of the second bidirectional screw 204 is connected to a second rotary motor, and one end of the first bidirectional screw 2 is connected to a first rotary motor. The top elastic pad, bottom elastic pad and side elastic pad ensure the support and clamping operation of the roller body. When the first bidirectional screw 2 rotates, it is used to drive the two sliding sleeve blocks 201 to move relative to each other. When the second bidirectional screw 204 rotates, it is used to drive the two U-shaped sleeve plates 205 to move relative to each other.

[0019] In this embodiment, a lifting rod 104 is connected between the top surface of the base block 1 and the bottom surface of the U-shaped mounting plate 103. Vertical holes are provided on the limiting columns 101. A horizontal bar corresponding to the vertical hole is fixed on the lifting arch plate 102. Through the setting of the clamping support assembly, the U-shaped support plate 202 supports the bottom of both ends of the roller body, the clamping vertical plate 206 supports the sides of both ends of the roller body, and the inverted L-shaped pressure rod 303 supports the top of the middle part of the roller body. This ensures that the roller body of different lengths and diameters can be supported, resulting in better stability and less impact on the processing operation of the roller ends. The rotating motor, the first rotating motor and the second rotating motor are servo motors with self-locking function in the prior art, and the lifting rod 104 and the telescopic rod 304 are electric telescopic rods in the prior art.

[0020] Working principle: When using this device to support the roller body, the U-shaped support plate 202 is adjusted relative to the length of the roller body. While placing the roller body on the bottom elastic pad, the clamping vertical plate 206 is controlled to move closer to the side elastic pad to clamp the side of the roller body. Then, the rotating motor is started, causing the worm gear 3 to rotate, thereby driving the worm wheel 301 and the vertical tube 302 to rotate and move closer to the roller body. The telescopic rod 304 retracts, causing the inverted L-shaped pressure rod 303 to press down to the top elastic pad support and contact the roller body. The lifting rod 104 is controlled to stretch or retract, and the height position of the roller body is adjusted. It should be noted that the operating trajectory of the rotating motor, the first rotating motor, the second rotating motor, the telescopic rod 304, and the lifting rod 104 is electrically calculated and controlled.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
