[0002] Pipes are materials used to make pipe fittings. Different pipe fittings require different pipes, and the quality of pipes directly determines the quality of pipe fittings. This type of pipe is often used in construction projects, power plants, chemical plants, etc., and the implementation standard is GB / T5310; for high-pressure boilers: the implementation standard is GB / T8163; seamless steel pipes for conveying fluids: the implementation standard is GB3087; seamless steel pipes for low-pressure boilers: the implementation standard is GB / T9948; seamless steel pipes for petroleum cracking: the implementation standard is GB / T14976; stainless steel seamless steel pipes for fluid conveying, common materials include alloys (15CrMo, 12Cr1MoV) carbon steel (10#, 20#, 45#) stainless steel (304, 316). Pipes are essential materials for construction projects, and commonly used ones include water pipes, drainage pipes, gas pipes, heating pipes, wire conduits, rainwater pipes, etc. With the development of science and technology, the pipes used in home decoration have also gone through the development process of ordinary cast iron pipes → cement pipes → (reinforced concrete pipes, asbestos cement pipes) → ductile iron pipes, galvanized steel pipes → plastic pipes and aluminum-plastic composite pipes.

[0003] In order to prevent corrosion and extend the service life of various pipes used in construction engineering, mine construction, bridge construction and other industries, it is necessary to spray coating on the surface of the pipes. However, the spraying production line is a production line for spraying pipes one by one. The pipes evenly distributed on the distribution bed need to be transported one by one to the spraying entrance roller. However, the commonly used distribution device often fails to distribute material or distributes multiple materials, which seriously affects the production rhythm. Summary of the invention

[0008] Specifically, the material dividing structure includes a material baffle plate, a transverse plate, a cylinder, a material dividing plate and a material receiving plate. The material baffle plate is installed on the top of the mounting plate, the transverse plate is fixed at one end of the support rod, and two cylinders in a symmetrical relationship are fixed at the bottom end of the transverse plate. The material dividing plate with an "L"-shaped structure is fixed at the same end of the two cylinders, and the end of the material dividing plate away from the cylinder is a triangular structure. The material receiving plate is fixed at the center position of the material dividing plate, and the material receiving plate forms an angle of 30° with the material dividing plate.

[0009] Specifically, the buffer structure includes a receiving groove, a buffer plate, a pin shaft and a second spring. The receiving groove having a rectangular structure is arranged on the receiving plate. The buffer plate is arranged inside the receiving groove, and the buffer plate is rotatably connected to the receiving plate through the pin shaft.

[0010] Specifically, the feeding structure includes a bracket, a column, a rotating rod, a roller, a second sprocket, a second chain, a first pulley, a third belt, a second pulley and a second motor.

[0011] Beneficial effects of the present invention:

[0012] (1) The automatic pipe feeding and steel dividing device described in the present invention can not only transport pipes through the setting of the transport structure, but also lay the pipes flat, so as to facilitate the subsequent pipe processing process. The transport structure can also synchronously drive the lubrication structure to work while transporting. Through the work of the lubrication structure, the transport structure can be fully oiled, which can not only avoid the jamming of the transport structure, but also prolong the service life of the transport structure. That is, since the first sprockets are rotated at both ends of the two mounting plates, and the first sprockets are driven by the first chain, and since the two first sprockets are rotatably connected to the rotating shaft through the second belt, that is, the rotation of the rotating shaft can realize the rotation of the two first chains, and since the first motor is rotatably connected to the rotating shaft through the first belt, when the first motor is working, the rotation of the two first chains can be realized, and when the pipes are pushed onto the two first chains, the pipes on the first chains will be moved along The first chain is moved along with the rotation of the first chain, and due to the continuous rotation of the first chain, it can ensure that the pipes on the first chain are in a flat state, thereby facilitating subsequent pipe processing, and when the rotating shaft is working, it will also drive the push rod fixed on the outside of the rotating shaft to rotate. The rotation of the push rod, combined with the elastic force of the first spring clamped between the pressure plate and the fixed sleeve, can make the pressure plate reciprocate inside the fixed sleeve, so that the airbag can be continuously squeezed, thereby inflating the airbag. Due to the internal connection between the airbag and the oil storage tank, the gas generated by the airbag will enter the interior of the oil storage tank. At this time, the internal air pressure of the oil storage tank increases, and the lubricating oil inside the oil storage tank can be squeezed to the sponge through the oil pipe, and the sponge can lubricate the first chain, thereby ensuring the normal operation of the first chain. Through the collecting groove set at the bottom of the first chain, the dripping lubricating oil can be collected centrally, and the collecting box is fixed at the bottom of the collecting groove, and the collected lubricating oil can be temporarily stored and reused.

[0013] (2) The automatic pipe feeding and steel dividing device described in the present invention can extract the pipes laid on the transport structure individually through the setting of the material dividing structure, thereby avoiding the situation where no material can be divided or multiple materials are divided during the material dividing, improving the efficiency of dividing the pipes one by one, and achieving the effect of improving the production rhythm. A buffer structure is also provided on the material dividing structure. Through the setting of the buffer structure, the pipes rolling down from the material dividing structure can be fully buffered, thereby avoiding the impact damage caused by the direct rolling of the pipes, and playing a role in protecting the pipes. When the pipes roll into the interior of the feeding structure, the feeding structure can be used to buffer the pipes. The materials are transported vertically to ensure that the spraying production line sprays the pipes one by one, so that the pipes evenly distributed on the fabric bed can be transported one by one, which can greatly improve the spraying efficiency and quality. That is, by installing a baffle plate on the top of the mounting plate, the flat pipes on the first sprocket can be blocked, thereby preventing the pipes from rolling down directly. When the pipes need to be divided individually, the cylinder works. Since the cylinder and the dividing plate are fixedly connected, the cylinder action will drive the dividing plate to move upward, and the dividing plate will be inserted from the gap between the two pipes. The continuous rise of the dividing plate can lift up the pipe on the first sprocket. When the dividing When the plate is lifted up until the baffle plate no longer blocks the pipe, the pipe will roll down along the receiving plate, thereby completing the single material distribution of the pipe, ensuring the subsequent spraying one by one, and improving the spraying quality and efficiency. In addition, since a buffer plate is rotatably connected to the receiving plate, and the buffer plate and the receiving plate are at a certain angle, a second spring is clamped and fixed between the buffer plate and the receiving plate, and the elastic force of the second spring can fully buffer the pipe rolling from the receiving plate, thereby preventing the pipe from being damaged by direct rolling. When the pipe rolls from the receiving plate onto the roller, the pipe can be conveyed one by one, and A plurality of groups of two columns are fixed on the top of the bracket, and a rotating rod is rotated between each group of columns. A roller is fixed on the outside of the rotating rod. By setting up multiple rollers, the pipes can be vertically conveyed. Since a second sprocket is fixed on the outside of each rotating rod, and the second sprocket is driven by a second chain, that is, only one rotating rod needs to be rotated to realize the synchronous rotation of multiple rotating rods. A first pulley is fixed on the outside of one of the rotating rods, and a second pulley is fixed on the outside of the second motor. The first pulley and the second pulley are rotatably connected by a third belt. Therefore, when the second motor is working, the roller can convey the pipes one by one.
