Description

Technical Field

[0001] This application relates to the technical field of corrugated pipe production equipment, and in particular to a corrugated pipe inspection and demolding device. Background Technology

[0002] A bellows is a tubular part with a ring-shaped corrugated structure, widely used in petroleum, chemical, construction, and machinery industries. During the production of bellows, the pipes need to be demolded from the mold and then subjected to quality inspection to ensure that the product meets relevant standards for subsequent processing and treatment.

[0003] A search revealed Chinese Patent Publication No. CN220438182U, which discloses a corrugated pipe quality inspection device. The device includes a rectangular inspection box with a through inlet / outlet on one side wall and the top wall; a cross-shaped positioning plate rotatably mounted within the inlet / outlet; a rotating plate and a driven plate rotatably mounted on the two side plates; two clamping plates fixedly connected to the rotating plate and driven plate respectively via second springs, with limit plates fixedly connected to their opposite faces; a movable frame movably mounted on the side wall of the inspection box; a drive motor fixedly connected to the movable frame, with a drive plate fixedly connected to the output end of the drive motor, and a drive groove on the rotating plate corresponding to the drive plate; several cameras fixedly connected inside the inspection box via a first mounting plate; and several lighting lamps fixedly connected inside the inspection box via a second mounting plate.

[0004] Regarding the aforementioned related technologies, the inventors have discovered the following drawbacks: Existing bellows inspection and demolding devices typically employ a single-station feeding method, meaning only one bellows can be fed, inspected, and demolded at a time. After one bellows completes inspection and demolding, the machine needs to be stopped for the next bellows, leading to frequent interruptions in the inspection and demolding process, low production efficiency, and difficulty in meeting the demands of mass production. To address the technical problem of low production efficiency and difficulty in meeting the demands of mass production caused by the single-station feeding method in existing bellows inspection and demolding devices, this application proposes a multi-station cyclic operation achieved by setting a first rotating rod with multiple feeding mechanisms. Combined with clamping components and other structures, this achieves the technical effect of improved production efficiency and facilitates comprehensive inspection. Utility Model Content

[0005] To improve the inspection efficiency of corrugated pipes, this application provides a corrugated pipe inspection and demolding device.

[0006] This application provides a corrugated pipe inspection and demolding device, employing the following technical solution: It includes a frame, on which a first rotating rod is rotatably connected; multiple feeding mechanisms are arrayed on the outer wall of the first rotating rod; each feeding mechanism includes a first driving rod fixedly connected to the first rotating rod, a first sliding rod slidably connected to the first driving rod in its axial direction, and a clamping assembly rotatably connected to the other end of the first sliding rod; the clamping assembly includes a first cylinder closed at both ends and hollow, with two radial tubes symmetrically arranged on the circumferential wall of the first cylinder communicating with its inner cavity; a radial rod is slidably connected inside each radial tube, the two radial rods being able to move in opposite directions or towards each other, and an inner support portion is provided at the end of each radial rod away from the first cylinder; an air valve communicating with its inner cavity is provided on the first cylinder. This multi-station approach improves the inspection efficiency of corrugated pipes and reduces equipment downtime.

[0007] Optionally, a first spring is sleeved on the outer wall of the first sliding rod; one end of the first spring is fixedly connected to the first driving rod, and the other end is fixedly connected to the first cylinder.

[0008] Optionally, a first linear driver is fixedly mounted on the frame, and a transmission rod is fixedly mounted on the output end of the first linear driver. When the first cylinder is vertically downward, the transmission rod can abut against the upper end face of the first cylinder.

[0009] Optionally, a second linear driver is fixedly mounted on the frame, and a rack is fixedly mounted on the output end of the second linear driver.

[0010] Optionally, a gear capable of meshing with a rack is coaxially fixed to the outer wall of the first cylinder.

[0011] Optionally, each radial tube has a first sliding groove on its inner wall, and each radial rod has a first sliding block on its outer wall that is adapted to the first sliding groove.

[0012] Optionally, a first motor is fixedly mounted on the frame, and the output shaft of the first motor is coaxially and fixedly connected to the first rotating rod.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. This utility model achieves multi-station synchronous operation of loading, inspection, and unloading processes by setting up multiple loading mechanisms and using the first rotating rod to drive them to rotate in a cycle. This avoids the situation where the machine needs to be stopped to load materials after completing the processing of a corrugated pipe in a single-station operation, reduces the interruption of the inspection and demolding process, thereby improving the overall production efficiency and meeting the needs of mass production.

[0015] 2. The clamping assembly of this utility model controls the inflation and deflation of the inner cavity of the first cylinder through an air valve, which drives the inner support part on the radial rod to move in opposite directions or towards each other. It can stably support or release the bellows from the inside, resulting in a good clamping effect. At the same time, the first spring can assist the clamping assembly to reset after the transmission rod is pushed. The second linear actuator can drive the bellows to rotate through the cooperation of rack and pinion to achieve multi-angle inspection. The operation is flexible and convenient, which helps to improve the comprehensiveness and accuracy of the inspection. Attached Figure Description

Detailed Implementation

[0022] The following is in conjunction with the appendix Figures 1-5 This application will be further described in detail below. The technical solutions in the embodiments of this application will be clearly described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0023] This application discloses a corrugated pipe inspection and demolding device. The device includes a frame 1, which serves as the mounting base for the entire device and supports various functional components. A first rotating rod 2 is rotatably connected to the frame 1 in the horizontal direction. One end of the first rotating rod 2 extends to the outside of the frame 1, and a first motor 3 is fixedly installed on the frame 1 at a position corresponding to the first rotating rod 2. The output shaft of the first motor 3 is coaxially and fixedly connected to the end of the first rotating rod 2 away from the frame 1 through a coupling. The first motor 3 can drive the first rotating rod 2 to rotate around its own axis.

[0024] Multiple feeding mechanisms (preferably 4 in this embodiment) are evenly arrayed along the circumference on the outer wall of the first rotating rod 2. The multiple feeding mechanisms can rotate synchronously with the first rotating rod 2 to realize multi-station cyclic operation.

[0025] Each feeding mechanism includes a first driving rod 4, a first sliding rod 5, and a clamping assembly. One end of the first driving rod 4 is vertically fixedly connected to the outer wall of the first rotating rod 2 and rotates synchronously with the first rotating rod 2. The first sliding rod 5 passes through the end of the first driving rod 4 away from the first rotating rod 2 and slides axially with the first driving rod 4 (i.e., the first sliding rod 5 can extend and retract relative to the first driving rod 4 along its own length direction). A first spring 6 is sleeved on the outer wall of the first sliding rod 5. One end of the first spring 6 is fixedly connected to the end of the first driving rod 4, and the other end is fixedly connected to the first cylinder 7 in the clamping assembly described below. When the first sliding rod 5 slides relative to the first driving rod 4, the first spring 6 can undergo elastic deformation and provide a restoring force.

[0026] The clamping assembly is used to clamp the bellows and includes a first cylinder 7, a radial tube 8, a radial rod 9 and an inner support 10. The first cylinder 7 is a hollow cylindrical structure with closed ends. One end of the cylinder is rotatably connected to the end of the first sliding rod 5 away from the first driving rod 4 through a bearing (so that the first cylinder 7 can rotate relative to the first sliding rod 5 around its own axis).

[0027] Radial tubes 8 are arranged radially along the first cylinder 7, and there are two or more of them. They are symmetrical about the axis of the first cylinder 7. One end of the radial tube 8 is fixedly connected to the peripheral wall of the first cylinder 7 and communicates with the inner cavity of the first cylinder 7, while the other end is open.

[0028] The radial rod 9 slides through the radial tube 8. The two radial rods 9 can move in opposite directions or towards each other along the radial direction of the first cylinder 7 within the two opposing radial tubes 8. To ensure the stability of the radial rod 9, the inner wall of each radial tube 8 is provided with a first sliding groove 11 along the length direction. The outer wall of each radial rod 9 is integrally formed with a first sliding block 12 that is adapted to the first sliding groove 11 at the corresponding position. The first sliding block 12 is embedded in the first sliding groove 11 and slides in cooperation.

[0029] The inner support 10 is fixed to the end of the radial rod 9 away from the first cylinder 7. It is preferably an arc-shaped block adapted to the inner wall of the bellows, with its arc-shaped surface facing the side away from the first cylinder 7. It is used to support and fix the bellows from the inside of the bellows. The outer wall of the radial rod 9 is fitted with a second compression spring (not shown in the figure). One end of the second compression spring is fixedly connected to the end face of the radial tube 8 away from the first cylinder 7, and the other end is fixedly connected to the inner support 10.

[0030] The air valve 13 is installed on the circumferential wall of the first cylinder 7 and communicates with the inner cavity of the first cylinder 7. The air valve 13 is connected to an external air pump (not shown in the figure) through an air pipe and is used to control the inflation and deflation of the inner cavity of the first cylinder 7.

[0031] To enable position and angle adjustment of the clamping components, the following components are also installed on frame 1:

[0032] The first linear actuator 14 and the transmission rod 15: The first linear actuator 14 (preferably a cylinder or electric push rod) is vertically fixed on the frame 1, with its output end facing downward and fixedly connected to the transmission rod 15; when the first rotating rod 2 drives the feeding mechanism to rotate to the feeding position, so that the first cylinder 7 is in a vertically downward state, the lower end of the transmission rod 15 can abut against the upper end face of the first cylinder 7; at this time, the first linear actuator 14 is activated, and the first cylinder 7 and the first sliding rod 5 can be pushed downward through the transmission rod 15 (compressing the first spring 6) to realize the height adjustment of the clamping assembly;

[0033] The second linear actuator 16, rack 17, and gear 18: The second linear actuator 16 (preferably a horizontally arranged cylinder or electric push rod) is fixed on the frame 1, and its output end is fixedly connected to the rack 17; the outer wall of the first cylinder 7 is coaxially fixedly fitted with the gear 18, and when the clamping assembly rotates to the inspection position, the gear 18 can mesh with the rack 17; starting the second linear actuator 16 drives the rack 17 to move, and the first cylinder 7 and the clamped bellows can be rotated through the gear 18, which facilitates multi-angle inspection.

[0034] Work process:

[0035] The working process of this device includes three main stations: loading, inspection, and unloading. Multi-station cycling is achieved through the rotation of the first rotating rod 2, as detailed below:

[0036] Loading station: The first motor 3 drives the first rotating rod 2 to rotate, causing one of the loading mechanisms to move to the loading position; at this time, the air valve 13 controls the air release in the inner cavity of the first cylinder 7, and the two radial rods 9 move towards each other under the action of the corresponding second compression springs, and the inner support 10 is in a contracted state; the first linear actuator 14 drives the first cylinder 7 to move down through the transmission rod 15, so that the bellows is sleeved on the outside of the inner support 10, and then the air valve 13 controls the air filling, the air pressure in the inner cavity of the first cylinder 7 increases, pushing the two radial rods 9 to move in opposite directions, the inner support 10 opens and presses against the inner wall of the bellows, completing the loading; then the first linear actuator 14 resets, and the first spring 6 drives the first cylinder 7 to reset;

[0037] Inspection station: The first motor 3 drives the first rotating rod 2 to rotate, which moves the loaded material feeding mechanism to the inspection station; at this time, the gear 18 meshes with the rack 17, and the second linear driver 16 is started to drive the rack 17 to move back and forth, which drives the bellows to rotate through the gear 18, so that the staff or testing equipment can conduct a comprehensive quality inspection of the bellows.

[0038] Unloading station: After the inspection is completed, the first rotating rod 2 continues to rotate, moving the loading mechanism to the demolding position. The air valve 13 releases air, the radial rods 9 move in opposite directions, the inner support 10 retracts and disengages from the bellows, and the bellows falls to the collection device under the action of gravity, completing the unloading.

[0039] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
