Description

Technical Field

[0001] This invention relates to the field of screw barrel repair technology, specifically to a repair device and repair method for extruder screw barrels. Background Technology

[0002] Screw extruders rely on the pressure and shear force generated by the rotation of the screw to fully plasticize and uniformly mix materials, which are then formed through a die. As the frequency of use of extruders gradually increases, the frequency of damage also gradually increases. In order to deal with the damage of screw extruders, corresponding repair devices have been designed for different parts of the screw extruder. Among them, the screw barrel is used frequently, and the corresponding damage rate is also increased. Therefore, a repair device has been designed for the screw barrel.

[0003] For example, Chinese utility model patent CN205020279U discloses a device for spraying paint on the surface of a winding machine cylinder. The device includes a base plate, a support plate on the base plate, a drive shaft between the ends of the support plate, a cylinder mounted on the drive shaft, a carrying plate on the outer wall of the support plate, a drive motor on the carrying plate, and the drive motor connected to the drive shaft. A paint sprayer is mounted on the base plate, with a main paint spraying pipe at both ends and branch paint spraying pipes at both ends. A paint sprayer housing is located between the ends of the branch paint spraying pipes, and the upper surface of the paint sprayer housing has several paint spraying holes. The cylinder is positioned above the paint sprayer housing. This utility model allows the paint liquid to be sprayed evenly onto the outer surface of the cylinder, greatly improving the efficiency of the paint spraying process.

[0004] However, the aforementioned devices only repair external scratches during actual use, making internal repairs difficult. Users cannot directly observe the internal condition, and they cannot handle screws and barrels of different diameters. Therefore, they do not meet current needs.

[0024] A repair method for a repair device used for extruder screw and barrel includes the following steps:

[0025] Step 1: Slide the screw barrel outside the second sliding block, and at the same time, attach the two sides of the lower end of the screw barrel to the upper end of the first rotating support base. After attachment, the motor drives the second rotating support base to rotate. The rotation can cause the second rotating support base to rotate around the third rotating axis outside the first rotating support base. The rotation can make the position adjustment wheel attach to the placed screw barrel.

[0026] Step 2: Simultaneously start the corresponding motors to drive the second and third transmission threaded rods to rotate. The rotation of the third and second transmission threaded rods can respectively drive the corresponding first and second sliding blocks to generate relative motion with them. After being restricted by the first and second limiting sliding rods respectively, the rotational motion is converted into linear motion, and the second sliding block and the detection camera, smearing strip, grinding strip and exhaust port on the outer side of the first transmission ring move laterally.

[0027] Step 3: The material extraction device extracts the repair fluid from the repair fluid storage chamber through the discharge pipe and transports it to the upper end of the trowel strip. The extension and retraction of the second telescopic adjustment rod pushes the trowel strip close to the screw barrel. After it is close, the rotation of the motor drives the trowel strip to move through the support rod, so that the material on the surface of the trowel strip is applied to the contact position.

[0028] Step 4: When grinding the protruding position, the grinding strip is pushed by the extension and retraction of the second telescopic adjustment rod so that the grinding strip fits with the protruding position for grinding. During the grinding and filling process, the position can be adjusted by the rotation of the first transmission ring outside the first sliding cavity. At the same time, the detection camera can track the repair position by rotating the second transmission ring outside the second sliding cavity.

[0029] Step 5: The rotation of the first and second adjustment discs can drive the exhaust port to rotate, and the exhaust port will discharge the gas drawn by the air extraction device, which can effectively clean up the debris generated by sanding and also effectively improve the drying speed of the applied items at the repair site.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] 1. This invention provides a second sliding block outside the third transmission threaded rod, a first sliding block outside the second transmission threaded rod, and a wiping strip on one side of the first and second sliding blocks. Additionally, a wiping strip and a polishing strip are provided on one side of the first and second sliding blocks. In actual use, the second and third transmission threaded rods drive the wiping strip and polishing strip to contact the inner and outer ends of the screw barrel, respectively. Both ends can be monitored simultaneously, and corresponding repairs can be performed. Repairing the screw barrel simultaneously improves the efficiency of screw barrel repair.

[0032] 2. The present invention provides a second sliding cavity on one side of both the second sliding block and the first sliding block, and a first sliding cavity on one side of the second sliding cavity. In actual use, the second transmission ring and the first transmission ring rotate outside the second sliding cavity and the first sliding cavity respectively, which can adjust the detection camera, the smearing strip and the grinding strip respectively. Furthermore, the rotation of the position adjustment wheel can drive the screw barrel to rotate. The multi-directional angle adjustment can facilitate the improvement of the device's repair efficiency for the screw barrel, thereby improving the repair efficiency and repair effect.

[0033] 3. The present invention connects the detection camera and the second transmission ring via a first rotating shaft, and connects the exhaust port and the first telescopic adjustment rod via a second rotating shaft. In actual use, the position of the exhaust port can be adjusted by extending and retracting the first telescopic adjustment rod, and the positions of the detection camera and the exhaust port can be adjusted by rotating the second rotating shaft and the first rotating shaft respectively.

[0060] A repair method for a repair device used for extruder screw and barrel includes the following steps:

[0061] Step 1: Slide the screw barrel 15 outside the second sliding block 11, and at the same time, attach the two sides of the lower end of the screw barrel 15 to the upper end of the first rotating support base 14.

[0064] Step 4: When grinding the protruding position, the grinding strip 25 is pushed by the extension and retraction of the second telescopic adjustment rod 34 so that the grinding strip 25 fits the protruding position for grinding. During the grinding and filling process, the position can be adjusted by the rotation of the first transmission ring 8 outside the first sliding cavity 16.

The exhaust port 29 discharges the gas extracted by the air extraction device 26, which can effectively clean up the debris generated by grinding and also effectively improve the drying speed of the applied items at the repair position.

5. A repair method based on the repair device for extruder screw and barrel as described in claim 4, characterized in that: Includes the following steps: Step 1: Slide the screw barrel (15) outside the second sliding block (11), and at the same time, attach the two sides of the lower end of the screw barrel (15) to the upper end of the first rotating support base (14). After attachment, the motor drives the second rotating support base (35) to rotate. The rotation can drive the second rotating support base (35) to rotate around the third rotating axis (36) outside the first rotating support base (14). The rotation can make the position adjustment wheel (37) attach to the placed screw barrel (15). Step 2: Simultaneously start the corresponding motor to drive the second transmission threaded rod (4) and the third transmission threaded rod (6) to rotate. The rotation of the third transmission threaded rod (6) and the second transmission threaded rod (4) can respectively drive the corresponding first sliding block (10) and the second sliding block (11) to generate relative motion with it. After being restricted by the first limiting sliding rod (5) and the second limiting sliding rod (7), the rotational motion is converted into linear motion, and the detection camera (18), the wiping strip (23), the grinding strip (25) and the exhaust port (29) on the outer side of the second sliding block (11) and the first transmission ring (8) move laterally. Step 3: The material extraction device (22) extracts the repair fluid from the repair fluid storage chamber (20) through the discharge pipe (21) and transports it to the upper end of the outside of the trowel strip (23). The extension and retraction of the second telescopic adjustment rod (34) pushes the trowel strip (23) close to the screw barrel (15). After it is close, the rotation of the motor drives the trowel strip (23) to move through the support rod (31) and make the material on the surface of the trowel strip (23) apply to the contact position. Step 4: When grinding the protruding position, the grinding strip (25) is pushed by the extension and retraction of the second telescopic adjustment rod (34) so ​​that the grinding strip (25) fits against the protruding position for grinding. During the grinding and filling process, the position can be adjusted by the rotation of the first transmission ring (8) outside the first sliding cavity (16). At the same time, the detection camera (18) can track the repair position by rotating outside the second sliding cavity (17) through the second transmission ring (9). Step 5: The rotation of the first adjustment plate (12) and the second adjustment plate (13) can drive the exhaust port (29) to rotate respectively. The exhaust port (29) will discharge the gas drawn by the air extraction device (26), which can effectively clean up the dust generated by grinding and also effectively improve the drying speed of the item applied to the repair position.
