[0035] See also Figure 1 A deep hole inner wall spray coating mechanism comprises: a rotating platform, a core pulling mechanism and a uniform material pressing device; the rotating platform is used to fix the tube body 2 and drive the tube body 2 to rotate during spraying; after the tube body 2 is fixed on the rotating platform, the upper end of the tube body 2 is used to hold the material; the core pulling mechanism is used to feed the core membrane rod 4 into the tube body 2 during spraying, and is also used to pull the core membrane rod 4 out of the tube body 2 after spraying is completed; the uniform material pressing device is used to feed the material in the feed hopper 3 between the core membrane rod 4 and the inner wall of the tube body 2, and press it.

[0036] The spray coating mechanism realizes a production process that combines mechanization, automation and manual operation, which not only greatly improves product production efficiency, reduces labor intensity, and improves the working environment, but also improves the uniformity and density of dressing laying, creating conditions for improving the quality of the inner wall dressing of the tube body and carrying out large-scale production.

[0037] Furthermore, the core pulling mechanism includes: a bracket 5; the bracket 5 includes a top plate and a bottom plate, and support rods are connected to the four corners between the top plate and the bottom plate; the bottom of the top plate of the bracket 5 is connected to a first lifting mechanism 6, and the first lifting mechanism can be a hydraulic cylinder, the telescopic end of the first lifting mechanism 6 faces downward, and the telescopic end of the first lifting mechanism 6 is connected to the core membrane rod 4.

[0038] The uniform pressing device includes: a second lifting mechanism 7 connected to the bottom of the top plate of the bracket 5, the telescopic end of the second lifting mechanism 7 faces downward, the second lifting mechanism 7 can be a hydraulic cylinder, the number of the second lifting mechanism 7 can be two, respectively located on both sides of the first lifting mechanism 6, two linear slide rails 9 are vertically connected to the bottom of the top plate of the bracket 5, the linear slide rails 9 are slidably connected to the linear slide rails 9, the side walls of the sleeves are connected to drive plates 10, the two drive plates 10 are connected to the side walls of the pressing barrel 8, and the pressing barrel 8 is a hollow tubular structure; the core membrane rod 4 is longer than the pressing barrel 8 and is slidably connected inside the pressing barrel 8.

[0039] The rotating platform includes: a motor 13 connected to the bottom of the bracket 5, the output end of the motor 13 is connected to a driving wheel 14, a frame 15 is connected to the bottom of the bracket 5, a reducer 16 is connected to the frame 15, an input end of the reducer 16 is connected to a driven wheel 17, a belt 18 is connected between the driving wheel 14 and the driven wheel 17, the output end of the reducer 16 is connected to a supporting platform 19, and a clamping mechanism is arranged on the supporting platform 19. The clamping mechanism can be two side plates 20, and a screw rod 21 is threadedly connected to the side plates 20. The end of the screw rod 21 is connected to a clamping plate 22 matching the outer wall of the tube body 2, and the tube body can be fixed by driving the clamping plate 22 by the screw rod 21.

[0040] Specifically, when in use, first apply the release agent and release grease on the surface of the core membrane rod 5 according to the process requirements, then use a lifting forklift (above the appropriate weight) to put the tube body 2 into the rotating workbench (not fixed yet), pass the core membrane rod 4 under the first lifting mechanism 6, and then fix the tube body 2 by the clamping mechanism after the core membrane rod 4 is lowered to the positioning center. It is necessary to measure the gap between the core membrane rod 4 and the inner wall of the tube body 2 to make them consistent, and then fix the feed hopper 3 at the upper end of the tube body 2 through a flange connection. When the rotating platform starts to rotate the tube body 2, the feed hopper 3 follows the low-speed rotation.

[0041] When the rotating platform starts to rotate the tube body 2, the feed hopper 3 begins to feed, and the second lifting mechanism 7 drives the pressing barrel 8 to move up and down to guide the material, thereby feeding the material evenly. When the tube body 2 stops feeding, the rotating platform, the tube body 2 and the feed hopper 3 do not rotate, and the second lifting mechanism 7 drives the pressing barrel 8 to start pressing the inner lining (pressing is performed repeatedly in layers) to ensure that the thickness of the tube body lining is uniform, dense and reliable.

[0042] When the lining pressing work of the tube body 2 is completed, the core-pulling membrane rod 4 is required. At this time, the pressing cylinder 8 stops at the upper end face of the lining of the tube body 2, and the core-pulling is carried out slowly to ensure that the surface of the lining of the tube body 2 is smooth and free of cracks. The core-pulling mechanism is used to shape the surface of the lining of the tube body 2 and control the uniformity of the wall thickness, and has the function of pressing the lining of tubes with equal diameters and different lengths.

[0043] It is worth mentioning that the inner wall dressing of the tube body is formed by the above-mentioned rotating platform, core pulling mechanism, feed hopper and uniform pressing device. After the dressing is completed, the molding precision is high, the density, strength and uniformity of the inner coating layer are greatly improved, and the product consistency is good; the labor productivity is improved and the labor intensity and safety protection of scientific and technological personnel are greatly reduced.

[0044] Furthermore, a shaft sleeve is connected to the linear slide rail 9, a sliding plate 11 is connected to the side wall of the shaft sleeve, a material-push-away blade 12 is connected to the sliding plate 11, and the material-push-away blade 12 is a U-shaped structure. The other end of the material-push-away blade 12 contacts the inner wall of the feed hopper 3. When the feed hopper 3 rotates with the tube body 2, the material-push-away blade 12 performs material-push, thereby achieving the purpose of uniform material distribution.

[0045] It should also be noted that for the compression of the lining of the square hole on the side of the pipe body, the square hole is blocked with a solid blind plate during compression. After the compression of the inner lining of the pipe body is completed and the core is pulled, the prepared auxiliary core mold is inserted and fixed, and then the pipe body is laid down and fixed with a clamp. The lining at the square hole is cut off manually with a special hole cutter, and then the square hole core mold is coated with a release agent and connected to the pipe body core mold. Start manual feeding, use the square hole sleeve for compression molding, and transfer it to the heat curing oven.

[0046] Secondly, for the compression scheme of the inner lining of the variable diameter pipe body, it is necessary to replace and configure the core mold rod and the pressing barrel that match the variable diameter pipe body, and complete the compression task of the pipe body lining in the actuator of the above-mentioned rotating platform, core pulling mechanism, feed hopper and uniform pressing device.

[0047] In addition, for the compression scheme of the heterogeneous spherical lining, a forming core mold (matched according to the characteristic shape and size of the product) needs to be configured separately to complete the compression task of the spherical lining in the above-mentioned actuator. The core pulling of the lining of various types of pipes can also be taken to the workbench for core pulling after heat curing. Burrs may appear at the pipe mouth and need to be manually polished smooth.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
