Abstract
Description
Technical Field
[0001] This utility model relates to the field of inner lining hose extrusion technology, and in particular to an ultraviolet light curing inner lining hose thickness adjustment extrusion device. Background Technology
[0002] The UV-cured pipe lining repair process is a type of in-situ curing method. It involves injecting adhesive into a sandwich-structured lining hose, then pulling a fiberglass-reinforced hose into the pipe section to be repaired, inflating it, and finally curing it under UV light to form a lining hose with a certain strength. This achieves the purpose of reinforcing and repairing the original pipe structure. After the adhesive injection is completed, the injected adhesive is often difficult to distribute evenly within the hose's sandwich structure. Therefore, during processing, the hose needs to be squeezed to adjust its thickness and ensure even distribution of the adhesive within the sandwich structure.
[0003] An existing UV-curable inner lining hose thickness adjustment and extrusion device (publication number: CN217752772U) has at least the following drawbacks: Although the above device moves the hose through a conveying mechanism and then adjusts the thickness of the hose through reciprocating back pressure rollers and fixed extrusion rollers, the hose in this device relies on the conveying mechanism to move, while the reciprocating back pressure rollers and fixed extrusion rollers are fixed in position on the conveying mechanism. When the hose still has uneven thickness after extrusion, the reciprocating back pressure rollers and fixed extrusion rollers cannot extrude it again, which easily leads to poor hose thickness adjustment effect and affects its performance and reliability. Therefore, we propose this utility model. Utility Model Content

[0023] like Figures 1-4As shown, a UV-curable inner lining hose thickness adjustment extrusion device includes a conveyor belt 1. A mounting frame 2 is provided on the top surface of the conveyor belt 1. The mounting frame 2 is U-shaped. An extrusion structure is provided above the conveyor belt 1. The extrusion structure includes two extrusion rollers 201 fixed inside the mounting frame 2. Side plates 202 are fixed on both sides of the conveyor belt 1. Two movable grooves 203 are opened on the top surface of the two side plates 202. The mounting frame 2 is slidably disposed inside the movable grooves 203. A lead screw 204 is rotatably disposed inside the movable groove 203 on the left side. The lead screw 204 is threadedly connected to the mounting frame 2.
[0024] In this embodiment, a servo motor is fixed to one side of the side plate 202. The output end of the servo motor passes through one side of the side plate 202 and is fixed to one end of the lead screw 204. A movable shell 205 is provided inside the mounting frame 2. The extrusion rollers 201 are rotatably arranged inside the movable shell 205. The two extrusion rollers 201 are arranged in parallel. A cylinder 206 is fixed to the top surface of the mounting frame 2. The telescopic end of the cylinder 206 passes through the top surface of the mounting frame 2 and is fixed to the top surface of the movable shell 205. A PLC controller is fixed to one side of the side plate 202. The cylinder 206 and the servo motor are both electrically connected to the PLC controller. Through the extrusion structure, the conveyor belt 1 transports the hose. The operator starts the cylinder 206 through the PLC controller. The cylinder 206 extends and drives the movable shell 205 to descend, causing the extrusion rollers 201 to move downwards. 01. The hose is compressed according to the required compression thickness. At this time, the compression roller 201 is fixed in a fixed position on the conveyor belt 1 to compress the hose for thickness adjustment. When there is still an uneven area after the hose is compressed at the fixed position, the operator starts the servo motor to drive the lead screw 204 to rotate. The rotation of the lead screw 204 drives the mounting frame 2 to move on the conveyor belt 1, so that the compression roller 201 moves to the area of the hose that has not been uniformly compressed for compression. The moving speed of the mounting frame 2 is greater than the conveying speed of the conveyor belt 1. At the same time, the servo motor can drive the mounting frame 2 to move back and forth on the conveyor belt 1 through the lead screw 204, so that the compression roller 201 can perform reciprocating compression and thickness adjustment on the hose, thereby improving the thickness adjustment effect of the device on the hose and ensuring the performance and reliability of the hose after thickness adjustment.
[0025] In this embodiment, a laser rangefinder 3 is fixed on the inner top surface of the mounting frame 2. The laser rangefinder 3 is located above the conveyor belt 1 and is electrically connected to the PLC controller. When the hose is pressed by the extrusion roller 201, the laser rangefinder 3 monitors the thickness of the extruded hose and feeds the monitoring data back to the PLC controller. If the extruded thickness is not up to standard, the PLC controller controls the servo motor and cylinder 206 to make the extrusion roller 201 press the hose to adjust its thickness.
[0026] In this embodiment, a limiting groove 4 is provided on one side of the inner wall of the right movable groove 203. A slide bar 401 is fixed on the right side of the mounting frame 2. The slide bar 401 and the limiting groove 4 are slidably arranged inside the mounting frame 2. When the mounting frame 2 moves under the action of the lead screw 204, the cooperation between the limiting groove 4 and the slide bar 401 can prevent the mounting frame 2 from shaking when it moves, thereby improving the stability of the device.
[0027] In this embodiment, the bottom surface of the slide bar 401 is rotatably provided with a number of rollers 5. The number of rollers 5 are evenly distributed along the length direction of the slide bar 401. The rollers 5 are slidably disposed inside the limiting groove 4. When the mounting bracket 2 slides in the movable groove 203, the slide bar 401 slides in the limiting groove 4. The number of rollers 5 can make its sliding smoother.
[0028] In this embodiment, two guide rods 6 are slidably inserted into the top surface of the mounting frame 2. The guide rods 6 pass through the top surface of the mounting frame 2 and are fixed to the top surface of the movable shell 205. When the cylinder 206 drives the movable shell 205 to rise and fall, the guide rods 6 can guide and limit the movement of the movable shell 205.
[0029] Working Principle: In operation, conveyor belt 1 transports the hose. The operator activates cylinder 206 via PLC controller. Cylinder 206 extends, causing movable housing 205 to descend, allowing extrusion roller 201 to extrude the hose according to the required extrusion thickness. At this time, extrusion roller 201 is fixed in position on conveyor belt 1, extruding the hose to achieve the desired thickness. If uneven areas remain after extrusion at the fixed position, the operator activates servo motor to rotate lead screw 204. The rotation of lead screw 204 moves mounting frame 2 on conveyor belt 1, causing extrusion roller 201 to move to the unevenly extruded area of the hose for extrusion. The moving speed of mounting frame 2 is greater than the conveying speed of conveyor belt 1. Simultaneously, the servo motor can rotate in both directions, driving mounting frame 2 to reciprocate on conveyor belt 1 via lead screw 204. The extrusion roller 201 can reciprocate to extrude and adjust the thickness of the hose. After the hose is extruded by the extrusion roller 201, the laser range sensor 3 monitors the thickness of the extruded hose and feeds the monitoring data back to the PLC controller. If the extruded thickness is not up to standard, the PLC controller controls the servo motor and cylinder 206 to make the extrusion roller 201 extrude and adjust the thickness of the hose. When the mounting frame 2 moves under the action of the lead screw 204, the matching of the limiting groove 4 and the slide bar 401 can prevent the mounting frame 2 from shaking during movement and improve the stability of the device. When the mounting frame 2 slides in the movable groove 203, the slide bar 401 slides in the limiting groove 4, and several rollers 5 can make its sliding smoother. When the cylinder 206 drives the movable shell 205 to rise and fall, the guide rod 6 can guide and limit the movement of the movable shell 205.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
