Description

Technical Field

[0001] This utility model relates to the field of roller straightening equipment technology, and in particular to a roller straightening device. Background Technology

[0002] Rollers, cylindrical parts, are divided into drive and driven rollers, and are used in various transmission and conveying systems such as printing machines, digital printers, papermaking and packaging machinery. They are mostly made of stainless steel, cast steel, or solid forged alloy steel cores.

[0003] For example, utility model application number 202121535142.X discloses a high-precision drive roller straightening device. By setting a fixed base and an adjustment device on the entire device, in use, the fixed frame is fixed to the upper left of the base, and the connecting column is connected to the lower front and upper front of the fixed frame. The straightening wheel is sleeved on the middle of the outer surface of the connecting column, and the connecting block is sleeved on the front and rear of the outer surface of the connecting column. The connecting plate is inserted between the two connecting blocks, and the bolt is connected to the middle of the upper part of the connecting plate. The bolt is threaded to the middle of the upper part of the support plate. By adjusting the bolt, the straightening wheel can be easily adjusted in terms of vertical distance and overall distance, thereby improving usability.

[0004] The above-mentioned applications still have shortcomings:

[0005] This type of high-precision drive roller straightening device can only straighten a local area when straightening the roller. The straightened part cannot be moved, and the roller needs to be manually slid back and forth to achieve a better straightening effect. It is very inconvenient to use, and the support part cannot be adjusted according to the size of the roller, resulting in low flexibility of use.

[0006] Therefore, a roller straightening device is designed to optimize the above problems. Utility Model Content

[0007] The main purpose of this utility model is to provide a roller straightening device to solve the related technical problems mentioned in the background art.

[0008] The objective of this utility model can be achieved by adopting the following technical solution:

[0009] A roller straightening device includes a fixed plate, a fixed frame fixed to the top of the fixed plate, sliding holes symmetrically opened on the top of the fixed frame, a motor mounted on one side of the fixed frame, a rotating shaft fixed to the output shaft of the motor, a bevel gear symmetrically mounted on the outer side of the rotating shaft, a fixed rod symmetrically mounted inside the fixed frame, a slider symmetrically threaded on the outer side of the fixed rod and slidably connected to the sliding hole, a straightening wheel fixed to the top of each slider, a bevel gear 2 fixed to one end of each fixed rod and meshing with the bevel gear 1, side frames symmetrically mounted on both sides of the fixed frame, a bidirectional screw rotatably mounted inside each side frame, a movable plate symmetrically threaded on the outer side of each bidirectional screw, and a conveyor wheel symmetrically rotatably mounted on one side of each movable plate.

[0010] Preferably: a second motor is installed at the middle position of the bottom of the fixed plate, a first sprocket is fixed to the output shaft of the second motor, rotating rods are rotatably installed at the bottom of both ends of the fixed plate, a second sprocket is fixed to the bottom of the rotating rod, a chain meshes between the second sprocket and the first sprocket, a sliding plate is threaded onto the outer side of the rotating rod, a support rod is fixed to the top of the sliding plate, a fixing block is fixed to the top of both ends of the fixed plate, a triangular block is symmetrically installed on the top of each fixing block, a support wheel is fixed to the top of each support rod, and the top of the support wheel passes through and extends between the triangular blocks.

[0011] Preferably, the top of each bidirectional screw is provided with a handle, and the outer side of the handle is provided with anti-slip texture.

[0012] Preferably, the movable plate is provided with a protective layer on the side near the side frame, and a sliding ball is provided on one side of the movable plate.

[0013] Preferably, the outer side of the conveyor wheel is provided with an anti-slip layer, and the outer side of the anti-slip layer is provided with anti-slip texture.

[0014] Preferably, each of the triangular blocks has a mounting groove on one side that is close to the other, and a ball bearing is rotatably installed inside the mounting groove.

[0015] The beneficial effects of this utility model are as follows:

[0016] This utility model provides a roller straightening device, which uses a fixed plate, a fixed frame, a sliding hole, a motor, a rotating shaft, a bevel gear, a fixed rod, a slider, a straightening wheel, a side frame, a bidirectional screw, a movable plate, a conveying wheel, and a bevel gear in cooperation. It can start the motor to drive the straightening wheel to move back and forth on both sides of the roller, so that the straightening wheel can perform multiple straightening operations on both sides of the roller. This not only improves the straightening efficiency but also the straightening effect, thereby improving the practicality of the roller straightening device.

[0017] By using the combined operation of motor two, sprocket one, rotating rod, sprocket two, chain, fixed plate, support rod, fixed block, triangular block, ball bearings, and support wheel, the roller is engaged at different depths between the triangular blocks according to its diameter. This causes the triangular blocks and ball bearings to limit and clamp the outer side of the roller. Motor two drives sprocket one, which in turn drives sprocket two and rotating rod to rotate via the chain. The rotating rod moves the slide plate and support rod upwards, and the support rod moves the support wheel up and down until the top of the support wheel contacts the bottom of the roller, providing support to the bottom of the roller and thus improving the stability during roller straightening.

[0023] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0024] Example 1

[0025] like Figures 1-4As shown, this embodiment provides a roller straightening device, including a fixed plate 1, a fixed frame 2 fixed to the top of the fixed plate 1, sliding holes 3 symmetrically opened on the top of the fixed frame 2, a motor 4 mounted on one side of the fixed frame 2, a rotating shaft 5 fixed to the output shaft of the motor 4, bevel gears 6 symmetrically mounted on the outer side of the rotating shaft 5, fixed rods 7 symmetrically mounted inside the fixed frame 2, sliders 8 symmetrically threaded on the outer side of the fixed rods 7, and the sliders 8 are slidably connected to the sliding holes 3, a straightening wheel 9 fixed to the top of each slider 8, a bevel gear 25 fixed to one end of each fixed rod 7, and the bevel gear 25 meshes with the bevel gear 6, side frames 10 symmetrically mounted on both sides of the fixed frame 2, and a bidirectional screw 11 rotatably mounted inside each side frame 10, the bidirectional screw 11... Movable plates 12 are symmetrically threaded on both sides of the fixed plate 1. Conveyor wheels 13 are symmetrically rotatably mounted on one side of each movable plate 12. Motor 2 14 is mounted at the middle of the bottom of the fixed plate 1. A sprocket 15 is fixed to the output shaft of motor 2 14. Rotating rods 16 are rotatably mounted at the bottom of both ends of the fixed plate 1. A sprocket 2 17 is fixed to the bottom of the rotating rod 16. A chain 18 meshes between sprocket 2 17 and sprocket 15. A sliding plate 19 is threaded on the outer side of the rotating rod 16. A support rod 20 is fixed to the top of the sliding plate 19. Fixing blocks 21 are fixed to the top of both ends of the fixed plate 1. Triangular blocks 22 are symmetrically mounted on the top of each fixing block 21. A support wheel 24 is fixed to the top of each support rod 20. The top of the support wheel 24 passes through and extends between the triangular blocks 22.

[0026] The roller passes sequentially between the conveyor wheel 13 and the straightening wheel 9, so that the end of the roller passes between the triangular blocks 22 at the other end. The starting motor 4 drives the rotating shaft 5 to rotate, the rotating shaft 5 drives the bevel gear 6 to rotate, the bevel gear 6 drives the bevel gear 25 and the fixed rod 7 to rotate, so that the fixed rod 7 drives the slider 8 and the straightening wheel 9 to move horizontally, and then move horizontally left and right on the outside of the roller. The straightening wheel 9 straightens the bent part of the roller. Depending on the diameter of the roller, the roller is locked at different depths between the triangular blocks 22, so that the triangular blocks 22 and the ball bearings 23 limit and clamp the outside of the roller. The starting motor 14 drives the sprocket 15, the sprocket 15 drives the sprocket 27 and the rotating rod 16 to rotate through the chain 18. The rotating rod 16 drives the slide plate 19 and the support rod 20 to move upward, and the support rod 20 drives the support wheel 24 to move up and down until the top of the support wheel 24 contacts the bottom of the roller, supporting the bottom of the roller.

[0027] Example 2

[0028] In this embodiment, as Figures 1-4 As shown, each of the two-way screws 11 has a handle at its top, and the outer side of the handle is provided with anti-slip texture.

[0029] The design of the handle and anti-slip texture facilitates the rotation and use of the bidirectional screw 11, improving ease of use.

[0030] In this embodiment, a protective layer is provided on the side of the movable plate 12 near the side frame 10, and a sliding ball is provided on one side of the movable plate 12.

[0031] The protective layer on one side of the movable plate 12 reduces friction damage, while the setting of the sliding ball makes the up-and-down movement of the movable plate 12 more stable.

[0032] In this embodiment, an anti-slip layer is provided on the outer side of the conveyor wheel 13, and anti-slip texture is provided on the outer side of the anti-slip layer.

[0033] The anti-slip layer and anti-slip texture increase the friction between the outer side of the conveyor wheel 13 and the roller, thus improving the limiting effect on the roller.

[0034] In this embodiment, each of the triangular blocks 22 has a mounting groove on one side that is close to each other, and a ball bearing 23 is rotatably mounted inside each mounting groove.

[0035] The friction between the triangular block 22 and the outer side of the roller is reduced by the mounting groove and the internal ball bearing 23.

[0036] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
