Description

Technical Field

[0001] The present application relates to the technical field of rock wool strip composite board production and processing equipment, and more specifically, to a coating device for producing rock wool strip composite boards. Background Art

[0002] Rock wool strip composite board, also known as rock wool color steel plate, is a kind of building material. Rock wool strip composite board is made by combining rock wool strips and color steel plates into a whole through automated equipment in the factory, thus changing the previous method of on-site compounding of rock wool boards. While meeting the requirements of thermal insulation, sound insulation, fire prevention, etc. of the building, it is also conducive to speeding up the construction.

[0003] The production and processing of color steel plates is an important link in the production and processing of rock wool strip composite panels. Before spraying anti-rust paint on the raw material surface of the color steel plate, it is necessary to first cut the smooth steel plate as the base material of the color steel plate into the required size, and then grind the surface of the cut smooth steel plate, press the grinded steel plate into a specific shape, and finally spray anti-rust paint on the surface of the smooth steel plate. Since the production of color steel plates has high requirements for the surface of the base material, it is necessary to grind the surface before painting it, and ensure that the surface of the steel plate is smooth and flat. Currently, when grinding the surface of the smooth steel plate, it is necessary to first use a grinding wheel to perform rough grinding to remove the rust layer on the surface of the steel plate, and then use sandpaper for fine grinding to make the surface of the steel plate smooth and flat, which is conducive to improving the adhesion of the subsequent coating layer.

[0004] At present, the surface of steel plates is mostly finely ground by sandpaper grinders. The sandpaper used for grinding in the sandpaper grinders is mostly installed on the grinding head of the sandpaper grinders by Velcro. The sandpaper is connected to the rough surface of the Velcro, and the bottom of the grinding head is connected to the hook surface of the Velcro. When using a sandpaper grinder to grind the surface of the steel plate, the sandpaper often needs to be replaced frequently due to wear. In the process of frequent replacement of sandpaper, the rough surface of the sandpaper and the hook surface of the grinding head are easily damaged during repeated tearing. In addition, during the replacement of sandpaper, dust and other impurities are also easily contaminated on the rough surface of the sandpaper and the hook surface of the grinding head, resulting in a decrease in the bonding force between the sandpaper and the grinding head. The sandpaper is easy to fall off from the grinding head during the grinding of the steel plate. While there are certain safety hazards, people will also need to frequently stop the machine and re-fix the sandpaper when grinding the steel plate surface, which prolongs the production and processing time of the color steel plate, thereby resulting in a decrease in the production and processing efficiency of the rock wool strip composite board.

[0005] In view of this, we propose a coating device for producing rock wool strip composite panels. Summary of the invention

[0017] Beneficial effects: One or more technical solutions provided in the technical solution of the present application have at least the following technical effects or advantages: 1. Control the extension of the second electric cylinder so that the grinding wheel is tightly attached to the surface of the steel plate, and then the high-speed rotating grinding wheel performs rough grinding on the surface of the steel plate. During the rough grinding process, the conveyor and the reciprocating cylinder cooperate to achieve grinding processing on different positions of the surface of the steel plate. After the rough grinding process, the first motor is turned off, the second electric cylinder is controlled to shorten, and then the second motor is controlled to turn on. The sandpaper assembly is driven by the second motor to rotate at a high speed, and then the first electric cylinder is controlled to shorten, so that the first electric cylinder drives the rotating sandpaper assembly to perform fine grinding on the surface of the steel plate. Similarly, during the fine grinding process, the conveyor and the reciprocating cylinder cooperate to achieve grinding processing on different positions of the surface of the steel plate.

[0018] 2. Before grinding the surface of the steel plate by means of a grinding wheel or sandpaper assembly, the third electric cylinder is controlled to extend so that the third electric cylinder drives the clamping roller to clamp and fix the steel plate to be ground, thereby preventing the steel plate from moving during the grinding process and ensuring the grinding effect of the steel plate.

[0019] 3. When pulling the extension rod on the magnetic buckle unit, the extension rod drives the approaching magnetic block that is magnetically attracted by the embedded magnetic block and squeezes the elastic capsule to gradually move away from the embedded magnetic block, and then the elastic capsule that was originally squeezed gradually returns to its original shape. In this process, the internal air pressure of the built-in cylinder gradually decreases, so that the end of the pin column gradually disengages from the reinforcing pin hole, and then the edge flip plate is flipped downward to disengage the hollow seat body from the corresponding embedded groove. Therefore, during the process of grinding the steel plate, when the worn sandpaper needs to be replaced, the operator can quickly remove the sandpaper installed on the grinding base.

[0020] 4. After removing the sandpaper installed on the grinding base, when installing the sandpaper to be replaced on the bottom of the grinding base, first fit the flexible base layer to the bottom surface of the grinding base, and then flip the edge flip plate connected to the edge of the flexible base layer upwards. When the edge flip plate is in contact with the side wall of the grinding base, the hollow base body enters the corresponding embedding groove. Under the magnetic attraction of the embedded magnetic block, the hollow base body is fixed in the embedding groove, thereby achieving the preliminary fixation of the sandpaper connected to the bottom of the flexible base layer on the grinding base.

[0021] 5. After the hollow seat body enters the embedded groove, under the action of the magnetic attraction of the embedded magnetic block, the approaching magnetic block quickly moves toward the embedded magnetic block and squeezes the elastic capsule in the compensation reinforcement mechanism. The elastic capsule continuously flows its internal gas into the inner cavity of the built-in cylinder through the opening during the elastic deformation caused by the squeezing of the embedded magnetic block. After the air pressure in the inner cavity of the built-in cylinder increases, the two bayonet columns are pushed to move in opposite directions, so that the ends of the bayonet columns are buckled into the corresponding reinforcing pin holes, thereby realizing the reinforcing fixation of the grinding sandpaper, so that the sandpaper is firmly installed on the bottom of the grinding base, and it is also convenient for the operator to replace the sandpaper.

[0022] 6. After the hollow seat body enters the embedded groove and approaches the magnetic block to squeeze the elastic capsule under the action of the magnetic attraction of the embedded magnetic block, the two bayonet columns move away from each other, forcing the plug seat to continuously inject the liquid medium into the annular groove through the shunt pipe. After the hydraulic pressure inside the annular groove increases, the feedback ring is pushed out from the inside of the annular groove. When the operator observes that the four feedback rings are extended from the inside of the corresponding annular grooves respectively, he can quickly identify that the sandpaper assembly has been correctly and firmly installed at this time, and can directly perform the next step of operation on the steel plate to be polished, which is beneficial to save the grinding processing time of the steel plate and improve the efficiency of the steel plate grinding processing.

[0023] 7. The reflective coating layer coated on the outer ring wall of the feedback ring enables the feedback ring to reflect light when it extends from the corresponding ring groove, forming an obvious reflective effect, which helps the operator to more easily find the feedback ring that has extended from the ring groove during the grinding operation.
