Description

Technical Field

[0001] This utility model relates to a rounding roller device, belonging to the technical field of plastic pipe manufacturing equipment. Background Technology

[0002] Currently, during the production process, plastic pipes are prone to elliptical deformation due to material properties and their own weight, which affects product quality and subsequent use.

[0003] After searching the existing technology, a Chinese patent with publication number CN205395101U was found to disclose a plastic pipe rounding mechanism. This patent uses a certain squeezing force applied to both sides of the pipe to resist the downward force of the pipe's own weight and achieve a balance, which improves the defect of the pipe deforming due to its own weight. However, it was found in use that the clamping is done by the opposite sides and needs to be adjusted on both sides. In actual production, people need to cross the production line back and forth, which not only affects work efficiency but also poses certain safety hazards. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a rounding roller device that can realize the synchronous adjustment of pipe rounding through one-sided operation, and can adapt to the rounding requirements of pipes of different specifications, thereby improving production efficiency and product quality.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a rounding idler roller device, comprising:

[0006] The base has a guide groove formed on its upper surface along its length.

[0007] A pair of uprights, the uprights being slidably disposed within guide grooves of the base, the lower end of the uprights being provided with nuts within the guide grooves;

[0008] A lead screw is rotatably mounted in the guide groove along the length of the base, one end of the lead screw extends out of one side of the base, and the lead screw passes through a pair of columns in sequence and is threadedly connected to the corresponding nuts;

[0009] A pair of fixing blocks are installed on the upper ends of corresponding columns. Each fixing block has an adjacent first mounting surface and a second mounting surface. A first roller with its axis perpendicular to the first mounting surface is provided on the first mounting surface, and a second roller with its axis perpendicular to the second mounting surface is provided on the second mounting surface. The angle between the axis of the first roller and the axis of the second roller is less than 180°. The corresponding first roller and second roller on the pair of columns combine to form a rhomboid channel suitable for rounding.

[0010] A drive assembly is mounted on one side of the base and is connected to the lead screw drive. The drive assembly is adapted to drive the lead screw to rotate, thereby causing the pair of columns to move towards each other or away from each other.

[0011] Furthermore, a specific structure for a driving component is provided, the driving component comprising:

[0012] A transmission box, which is fixedly mounted on one side of the base;

[0013] A speed reduction mechanism is disposed inside the transmission box. The speed reduction mechanism has an input end and an output end. One end of the output end is connected to the lead screw drive, and the input end extends out of the transmission box.

[0014] A drive input device is fixedly installed on the outside of the transmission box and is drive-connected to the input end of the reduction mechanism.

[0015] Furthermore, a specific structure for a speed reduction mechanism is provided, the speed reduction mechanism comprising:

[0016] A worm gear is rotatably mounted inside the transmission box, and the worm gear is fixedly sleeved on the end of the lead screw as the output end;

[0017] A worm gear is rotatably mounted inside the transmission box. The worm gear serves as the input end and is connected to the drive input device. The worm gear meshes with the worm wheel for transmission.

[0022] Furthermore, the first idler roller includes:

[0023] The idler roller shaft is fixedly mounted on the fixed block;

[0024] The roller body is rotatably mounted on the idler roller shaft.

[0025] Furthermore, a specific material for the roller body is provided, wherein the roller body is made of nylon.

[0026] Furthermore, the rounding roller device also includes a measuring ruler, which is fixedly mounted on the base along the length direction of the base, and the measuring ruler is engraved with scale lines.

[0027] By adopting the above technical solution, this utility model has the following beneficial effects:

[0028] In this invention, during use, the round tube to be calibrated is first measured, and then the screw is rotated by the drive assembly, which causes the column sliding on the guide groove of the base to move towards or away from each other until the diamond-shaped channel formed by the first roller and the second roller installed on the fixed block of the column matches the round tube to be calibrated.

[0039] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0040] Example 1: As Figure 1-8 As shown, a rounding idler roller device includes:

[0041] The base 1 has a guide groove 11 formed on its upper surface along its length.

[0042] A pair of uprights 2 are slidably mounted in the guide groove 11 of the base 1, and the lower end of the uprights 2 in the guide groove 11 is provided with a nut;

[0043] The lead screw 3 is rotatably installed in the guide groove 11 along the length of the base 1. One end of the lead screw 3 extends out of one side of the base 1. The lead screw 3 passes through a pair of columns 2 in sequence and is threadedly connected to the corresponding nuts.

[0044] A pair of fixing blocks 41 are installed on the upper end of corresponding columns 2. The fixing blocks 41 are provided with adjacent first mounting surfaces and second mounting surfaces. A first roller 42 with its axis perpendicular to the first mounting surface is provided on the first mounting surface, and a second roller with its axis perpendicular to the second mounting surface is provided on the second mounting surface. The angle between the axis of the first roller 42 and the axis of the second roller is less than 180°. The corresponding first roller 42 and second roller on the pair of columns 2 are combined to form a diamond-shaped channel suitable for rounding.

[0045] Drive assembly 5 is installed on one side of base 1. Drive assembly 5 is connected to lead screw 3 for transmission. Drive assembly 5 is adapted to drive lead screw 3 to rotate, thereby driving a pair of columns 2 to move towards each other or away from each other.

[0046] In this embodiment, as Figure 1-3 and Figure 6 As shown, during use, the round tube to be calibrated is first measured, and then the screw 3 is rotated by the drive assembly 5, which in turn drives the column 2 sliding on the guide groove 11 of the base 1 to move towards or away from each other until the diamond-shaped channel formed by the first roller 42 and the second roller installed on the fixed block 41 of the column 2 matches the round tube to be calibrated, and the round tube to be calibrated passes through the diamond-shaped channel to achieve roundness calibration.

[0047] When the rounding roller device is working, the lead screw 3 is threadedly connected to the nut at the lower end of the column 2, converting the rotational motion into the linear motion of the column 2. A set of first rollers 42 and second rollers on the fixed block 41 form a diamond-shaped channel. The size of the diamond-shaped channel can be adjusted by the drive assembly 5 to accommodate pipes of different specifications. The base 1 includes two parts: a slide frame with guide grooves 11 and a base plate installed at the bottom of the slide frame and connected to the drive assembly 5.

[0048] The drive assembly 5 drives the lead screw 3 to rotate via a reduction mechanism within the transmission box 51. The reduction mechanism provides sufficient output torque, ensuring smooth and controllable movement of the column 2, while requiring only a small input force to drive the lead screw 3 to rotate. The first and second idlers engage in rolling contact with the pipe, reducing frictional resistance and preventing scratches on the pipe surface. Throughout the rounding process, the pipe passes through the diamond-shaped channel under its own weight, with the first and second idlers acting simultaneously to correct the outer roundness of the pipe.

[0049] Specifically, such as Figure 1-3 and Figure 5 As shown, the driving component 5 includes:

[0050] Transmission box 51, which is fixedly installed on one side of base 1;

[0051] The speed reduction mechanism is located inside the transmission box 51. The speed reduction mechanism has an input end and an output end. One end of the output end is connected to the lead screw 3 for transmission, and the input end extends out of the transmission box 51.

[0052] The drive input device 53 is fixedly installed on the outside of the transmission box 51 and is connected to the input end of the reduction mechanism.

[0053] Specifically, such as Figure 2 and Figure 5 As shown, the reduction mechanism includes:

[0054] The worm gear is rotatably installed inside the transmission box 51, and the worm gear is fixedly sleeved on the end of the lead screw 3 as the output end;

[0055] The worm gear is rotatably installed inside the transmission box 51. The worm gear serves as the input end and is connected to the drive input device 53 for transmission. The worm gear and the worm wheel mesh with each other for transmission.

[0056] In this embodiment, as Figure 1-3 and Figure 5As shown, the drive assembly 5 is located on the side of the base 1. It drives the lead screw 3 to rotate via a reduction mechanism within the transmission box 51. The reduction mechanism employs a worm gear transmission, with the worm wheel fixedly sleeved at the end of the lead screw 3. The worm is connected to the drive input device 53. When the drive input device 53 drives the worm to rotate, a large reduction ratio can be achieved through the meshing transmission between the worm and the worm wheel, enabling the lead screw 3 to obtain a stable speed output. This transmission structure has a self-locking function, preventing the column 2 from shifting under external forces.

[0057] This transmission structure enables the rounding roller device to be powered by the drive input device 53 during operation. After being reduced in speed by the reduction mechanism, the power is output to the lead screw 3, which in turn drives the column 2 to move.

[0058] Specifically, such as Figure 5 As shown, the drive input device 53 includes:

[0059] A manual crank is provided on the outside of the transmission box 51, and the manual crank is connected to the input end of the reduction mechanism extending out of the transmission box 51.

[0060] In this embodiment, as Figure 2 As shown, the manual crank is manually driven. The operator rotates the manual crank to drive the reduction mechanism, thereby controlling the lead screw 3. The manual crank allows the rounding roller device to operate normally in environments without power supply, facilitating the rounding adjustment of pipes of different specifications. The manual crank has a circular structure with a raised handle.

[0061] Specifically, such as Figure 6-8 As shown, the first idler roller 42 includes:

[0062] The idler roller shaft 421 is fixedly mounted on the fixed block 41.

[0063] Roller body 422 is rotatably sleeved on roller shaft 421;

[0064] The limiting retaining ring is fixed at both ends of the idler roller shaft 421 and is suitable for limiting the axial movement of the roller body.

[0065] Specifically, such as Figure 7-8 As shown, the roller body 422 is made of nylon.

[0066] In this embodiment, as Figure 1-2 As shown, the roller body 422 is sleeved on the idler roller shaft 421 and achieves relative rotation through bearings.

[0067] Example 2: This example is basically the same as Example 1, except that:

[0068] Specifically, such as Figure 1 and Figure 4 As shown, the round roller alignment device also includes a measuring ruler 6, which is fixedly mounted on the base 1 along the length of the base 1, and the measuring ruler 6 is engraved with scale lines.

[0069] In this embodiment, as Figure 1 and Figure 4 As shown, the measuring ruler 6 is fixedly installed on the base 1 and extends along the direction of the guide groove 11. The scale lines of the measuring ruler 6 are used to display the actual distance between the columns 2, providing an intuitive reference for operators to adjust the dimensions of the diamond-shaped channel. Operators can accurately adjust the position of the columns 2 by observing the scale values ​​on the measuring ruler 6 according to the outer diameter of the round pipe to be calibrated.

[0070] Example 3: This example is basically the same as Example 1, except that:

[0071] Specifically, the drive input device 53 includes:

[0072] A drive motor (not shown in the figure) is fixedly mounted on the outside of the transmission box 51. The output end of the drive motor extends into the inside of the transmission box 51 and is connected to the input end of the reduction mechanism.

[0073] In this embodiment, the drive motor can be a servo motor.

[0074] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
