Description

Technical Field

[0001] This utility model relates to the field of double-wall corrugated pipe production technology, specifically a dual-station rolling forming device for double-wall corrugated pipes. Background Technology

[0002] In the production and processing of double-wall corrugated pipes, rolling is one of the core processes, which directly affects product quality and production efficiency. Rolling equipment is required in the rolling process.

[0003] Traditional double-wall corrugated pipe rolling forming equipment mostly adopts a single-station design, which can only roll one substrate at a time. When mass production is required, the processing cycle is long and the efficiency is low, making it difficult to meet the capacity requirements of modern production. From the perspective of the drive system, the drive structure of traditional equipment is mostly a decentralized design, with each rolling roller often driven by an independent motor. This can easily lead to asynchronous speeds, resulting in inconsistent rolling accuracy of the substrate and large deviations in the dimensions of the finished product, which increases the defect rate. Additional manpower and resources are required for correction afterward, increasing production costs.

[0004] In terms of ease of operation, traditional equipment relies heavily on manual handling for material loading, which is not only labor-intensive but also prone to inaccurate positioning of the substrate due to human error. After rolling, the unloading process is also cumbersome, and some equipment requires disassembling part of the structure to remove the finished product, which is time-consuming and labor-intensive, further reducing the overall production efficiency. Against this background, we propose a dual-station rolling forming device for double-wall corrugated pipes. Utility Model Content

[0005] The purpose of this invention is to provide a dual-station rolling forming device for double-wall corrugated pipes. By setting up a dual-station rolling assembly, the problem of low processing efficiency in traditional single-station processing is solved; and by using a drive assembly, the problems of poor synchronization and unstable drive in dual-station rolling are solved.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A dual-station rolling forming device for double-wall corrugated pipes includes a base plate and two substrates. A conveyor is mounted on the top surface of the base plate, and the two substrates are located on the top surface of the conveyor belt. A rolling mechanism is provided near the right end of the top surface of the base plate. The rolling mechanism includes two mutually symmetrical rolling components. Each rolling component includes a fixed plate and a mounting plate fixed to the top surface of the base plate, two lower rotating rollers rotatably connected between the mounting plate and the fixed plate, two active rolling rollers coaxially fixed to the outer circumference of the lower rotating rollers on the same side and used for rolling the substrates, and two pulleys located above the base plate for driving the two lower rotating rollers to rotate. The rolling mechanism also includes:

[0008] A drive assembly, located on the top surface of the base plate, is used to drive four active rolling rollers to rotate. The drive assembly includes a turbine mounted on the top surface of the base plate and used to drive two lower rollers on the same side to rotate synchronously in the front-back direction, a worm gear mounted on the top surface of the base plate and meshing with the turbine, and a drive motor mounted on the top surface of the base plate and used to drive the worm gear to rotate.

[0009] In a preferred embodiment, the drive assembly further includes a rotating rod coaxially fixed between any one of the lower rotating rollers in the front rolling assembly and the lower rotating rollers on the same side in the rear rolling assembly, and the turbine is coaxially fixed on the outer circumferential wall of the rotating rod.

[0010] In a preferred embodiment, the drive assembly further includes a placement plate fixed between two mounting plates, the drive motor is mounted on the top surface of the placement plate, the worm gear is rotatably connected between the placement plate and the base plate, and the output shaft of the drive motor is coaxially connected to the worm gear.

[0011] These two settings enable the lower rollers on the same side of the front and rear rolling assemblies to rotate synchronously, ensuring the synchronization of rolling in both stations, allowing the drive motor to be stably installed and precisely drive the worm gear, thus improving drive stability.

[0012] In a preferred embodiment, the two lower rollers in the rolling assembly are arranged from left to right and are parallel to each other. The two pulleys on the same side are coaxially fixed on the outer circumference of the two lower rollers on the same side, and the two pulleys on the same side are connected by belt drive.

[0013] In a preferred embodiment, the rolling assembly further includes an upper roller that is rotatably connected to the mounting plate and located above the two lower rollers on the same side, and a driven rolling roller is coaxially fixed on the outer circumferential wall of the upper roller.

[0014] In a preferred embodiment, the driven rolling roller is positioned and sized to correspond with the two active rolling rollers on the same side, and the substrate is positioned and sized to correspond with both active rolling rollers on the same side.

[0015] In a preferred embodiment, the rolling assembly further includes a flipping plate hinged to the top surface of the fixed plate, the outer wall of the flipping plate being provided with a rotating hole that cooperates with the upper rotating roller on the same side, and the rolling assembly further includes an electric cylinder whose cylinder body is hinged to the top surface of the base plate and whose piston rod is hinged to the flipping plate.

[0016] These four settings enable the two lower rollers on the same side to rotate synchronously, ensuring that the active rolling rollers on the same side work synchronously, allowing the driven rolling rollers to cooperate with the active rolling rollers to improve the rolling effect of the substrate, ensuring accurate positioning of the substrate during the rolling process, guaranteeing rolling accuracy, and enabling the electric cylinder to drive the flipping plate to flip, making it easier to unload the rolled double-wall corrugated pipe and reducing the difficulty of unloading.

[0017] In a preferred embodiment, an anti-slip plate adapted to the shape of the base plate is fixed on the bottom surface of the base plate. The thickness of the anti-slip plate is 3cm-7cm, and the bottom surface of the anti-slip plate is provided with anti-slip texture.

[0018] This feature prevents the device from sliding when placed, improving its stability during operation.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This utility model, through the setting of the base plate and the conveyor, realizes the stable and orderly transmission of the substrate to be rolled, eliminating the need for manual handling of the substrate and accurately delivering raw materials for subsequent rolling operations; at the same time, the dual-station design of the two symmetrical rolling components in the rolling mechanism enables the rolling operation of two substrates simultaneously, changing the traditional mode of processing only one substrate at a time in a single station, greatly shortening the processing time for the same output, achieving the effect of significantly improving the overall production efficiency of the device and increasing the productivity of the production device, thus meeting the needs of mass production;

[0021] 2. This utility model, through the setting of the drive component in the rolling mechanism, utilizes the drive motor to drive the worm gear to rotate, and the worm gear meshes with the turbine to drive the rotating rod. With the help of pulleys and belt transmission, it realizes the synchronous and unidirectional rotation of the four active rolling rollers in the two rolling components, avoiding the difference in rolling accuracy caused by the different speeds of the rolling rollers. At the same time, the design of the flipping plate and electric cylinder in the rolling component enables convenient removal of the double-wall corrugated pipe after rolling, without the need for laborious disassembly or prying of the finished product. This achieves the effects of ensuring the consistency of rolling operation, improving product quality, reducing manual operation intensity, and improving the convenience of unloading.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0032] Please see Figures 1-7 The present invention provides a technical solution: a dual-station rolling forming device for double-wall corrugated pipes, including a base plate 1 and two substrates 4. A conveyor 2 is installed on the top surface of the base plate 1, and the two substrates 4 are located on the top surface of the conveyor belt of the conveyor 2. A rolling mechanism 3 is provided on the top surface of the base plate 1 near the right end. The rolling mechanism 3 includes two mutually symmetrical rolling components 31. The rolling component 31 includes a fixed plate 311 and a mounting plate 312 fixed on the top surface of the base plate 1, two lower rollers 313 rotatably connected between the mounting plate 312 and the fixed plate 311, two active rolling rollers 314 coaxially fixed on the outer circumference of the lower rollers 313 on the same side and used to roll the substrates 4, and two pulleys 317 located above the base plate 1 and used to drive the two lower rollers 313 to rotate.

[0033] By setting up the base plate 1 and the conveyor 2, the substrate 4 that needs to be rolled can be transported. By designing the two rolling components 31 in the rolling mechanism 3, two substrates 4 can be rolled at the same time.

[0034] In this embodiment, the two lower rollers 313 in the rolling assembly 31 are arranged from left to right and are parallel to each other. The two pulleys 317 on the same side are coaxially fixed on the outer circumference of the two lower rollers 313 on the same side, and the two pulleys 317 on the same side are connected by a belt 318.

[0035] The two parallel lower rollers 313 in the rolling assembly 31 and the two belt pulleys 317 driven by the belt drive make the lower rollers 313 on the same side rotate synchronously, ensuring that the rotation speed of the active rolling rollers 314 on the same side is consistent, thus ensuring the rolling effect of a single station.

[0036] In addition, the rolling assembly 31 also includes an upper roller 315 that is rotatably connected to the mounting plate 312 and located above the two lower rollers 313 on the same side, and a driven rolling roller 316 is coaxially fixed on the outer circumferential wall of the upper roller 315.

[0037] The upper rotating roller 315, which is rotatably connected to the mounting plate 312 in the rolling assembly 31, and the coaxial driven rolling roller 316, enable the driven rolling roller 316 to cooperate with the active rolling roller 314 to roll the substrate 4 from above, thereby improving the rolling accuracy.

[0038] Furthermore, the driven rolling roller 316 is positioned and its dimensions are matched with the two active rolling rollers 314 on the same side, and the substrate 4 is positioned and its dimensions are matched with the two active rolling rollers 314 on the same side.

[0039] By using the driven rolling roller 316 and the active rolling roller 314 with corresponding positions and adapted sizes, and the adapted substrate 4, the substrate 4 is accurately positioned during rolling and is not easily deviated, which further ensures the accuracy of the rolling size and reduces defects in the finished product.

[0040] Specifically, the rolling assembly 31 also includes a flipping plate 319 hinged to the top surface of the fixed plate 311. The outer wall of the flipping plate 319 is provided with a rotating hole that cooperates with the upper rotating roller 315 on the same side. The rolling assembly 31 also includes an electric cylinder 3110 whose cylinder body is hinged to the top surface of the base plate 1 and whose piston rod is hinged to the flipping plate 319.

[0041] The rotating plate 319 with a rotating hole and the electric cylinder 3110 hinged in the rolling assembly 31 enable the electric cylinder 3110 to drive the rotating plate 319 to rotate, which facilitates the removal of the formed corrugated pipe, reduces the labor intensity of unloading, and improves the operating efficiency.

[0042] like Figures 1-7 As shown, it is worth noting that the rolling mechanism 3 also includes: a drive assembly 32, which is disposed on the top surface of the base plate 1 and is used to drive four active rolling rollers 314 to rotate. The drive assembly 32 includes a turbine 322 mounted on the top surface of the base plate 1 and used to drive two lower rollers 313 on the same side to rotate synchronously in the front-back direction; a worm gear 324 mounted on the top surface of the base plate 1 and meshing with the turbine 322; and a drive motor 325 mounted on the top surface of the base plate 1 and used to drive the worm gear 324 to rotate.

[0043] The design of the drive component 32 in the rolling mechanism 3 also facilitates the synchronous and unidirectional rotation of the four active rolling rollers 314 in the two rolling components 31, thereby ensuring the consistency of the rolling operation. At the same time, the dual-station design also improves the production efficiency of the entire device and increases the productivity of the entire production device.

[0044] It is worth noting that the drive assembly 32 also includes a rotating rod 321 coaxially fixed between any one of the lower rotating rollers 313 in the front rolling assembly 31 and the lower rotating rollers 313 on the same side in the rear rolling assembly 31, and the turbine 322 is coaxially fixed on the outer circumferential wall of the rotating rod 321.

[0045] The rotating rod 321 in the drive assembly 32 connects the lower rotating roller 313 and the turbine 322 on the same side of the front and rear rolling assemblies 31, so that the lower rotating roller 313 on the same side of the front and rear sides rotate synchronously, ensuring that the rolling action of the two stations is consistent and reducing processing differences.

[0046] It is worth emphasizing that the drive assembly 32 also includes a placement plate 323 fixed between the two mounting plates 312, a drive motor 325 mounted on the top surface of the placement plate 323, and the rod of the worm gear 324 rotatably connected between the placement plate 323 and the base plate 1, and the output shaft of the drive motor 325 is coaxially connected with the rod of the worm gear 324.

[0047] The drive assembly 32 has a placement plate 323, a drive motor 325 mounted on it, and a worm gear 324 rotatably connected to it. This allows the drive motor 325 to be stably installed and the worm gear 324 to be precisely driven, thereby improving the stability and reliability of the drive system.

[0048] like Figures 1-2 As shown, it is worth noting that an anti-slip plate 11 that matches the shape of the base plate 1 is fixed on the bottom surface. The thickness of the anti-slip plate 11 is 3cm-7cm, and the bottom surface of the anti-slip plate 11 is provided with anti-slip texture.

[0049] The thickness of the anti-slip plate 11 is preferably 4cm, which makes the device less prone to slipping when placed, enhances the stability during operation, avoids affecting the rolling process due to device displacement, and ensures a smooth processing flow.

[0050] It should be added that the two electric cylinders 3110, the drive motor 325, and the transmission motor in the transmission machine 2 are all electrically connected to the external PLC and the external power supply through wires, and the external PLC is also electrically connected to the external power supply through wires.

[0051] Finally, it should be noted that the two electric cylinders 3110, the drive motor 325, and the transmission motor in the transmission machine 2 involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle in this utility model. The electrical connection between each electrical component is completed in the order of operation. The detailed connection method is a technology known in the art.

[0052] In practical use, this embodiment includes the following steps:

[0053] 1. Material feeding and conveying stage: The external PLC controls the start of the conveyor motor of the conveyor 2, and the conveyor belt of the conveyor 2 drives the two substrates 4 on it to move towards the rolling mechanism 3 until the substrates 4 reach the processing positions of the two rolling components 31 respectively, and the PLC controls the conveyor motor to stop.

[0054] 2. Rolling preparation stage: The external PLC controls the start of the electric cylinders 3110 of the two rolling components 31. The piston rod of the electric cylinder 3110 extends and retracts, causing the flip plate 319 to flip, so that the upper roller 315 and the driven rolling roller 316 are adjusted to the processing position that matches the substrate 4. Then the PLC controls the electric cylinder 3110 to stop.

[0055] 3. Rolling Processing Stage: The external PLC controls the start of the drive motor 325 of the drive assembly 32, which drives the worm gear 324 to rotate. The worm gear 324 meshes with the worm wheel 322 to drive the rotating rod 321 to rotate, which in turn drives the lower roller 313 on the same side of the front and rear rolling assemblies 31 to rotate. At the same time, the pulley 317 on the same side drives the other lower roller 313 on the same side to rotate through the belt 318, so that the four active rolling rollers 314 rotate synchronously and in the same direction, and cooperate with the driven rolling roller 316 to roll the two substrates 4. After the processing is completed, the PLC controls the drive motor 325 to stop.

[0056] 4. Unloading stage: The external PLC controls the two electric cylinders 3110 to start again. The electric cylinders 3110 drive the tilting plate 319 to flip in the opposite direction, opening the processing area. The worker takes off the rolled double-wall corrugated pipe. Then the PLC controls the electric cylinders 3110 to reset, and the device is ready to enter the next processing cycle.
