Description

Technical Field

[0001] This utility model relates to the field of spraying technology, and in particular to a steel pipe spraying and drying integrated machine. Background Technology

[0002] In the steel pipe manufacturing and processing industry, painting the outer surface of steel pipes is a common process. The purpose is to protect the steel pipes from external environmental corrosion through a coating, extending their service life and improving their appearance. After painting, the steel pipes must be dried to allow the coating to cure quickly and ensure adhesion and performance stability.

[0003] Currently, the painting and drying processes for steel pipes are typically completed in separate equipment or workshops. Specifically, operators first place the steel pipes in the painting equipment for painting, and after painting, the pipes are then transferred to the drying equipment manually or using transport equipment for drying. This step-by-step operation mode has obvious drawbacks: on the one hand, the transfer process not only consumes additional manpower and time, reducing overall production efficiency, but also the coating on the outer surface of the freshly painted steel pipes has not yet cured, making it susceptible to damage and contamination due to collisions, friction, or dust during transfer, affecting product quality; on the other hand, independently set up painting and drying rooms require more production space, increasing site costs.

[0004] Meanwhile, the method of fixing the steel pipe during the painting process also affects the painting effect. In existing technologies, steel pipes are mostly fixed by brackets or clamps. During painting, the outer surface of the steel pipe is usually sprayed manually by holding the spray gun or using a fixed spray gun. Because the steel pipe has a cylindrical structure, the support points or clamping parts are prone to forming painting dead zones when using traditional fixing methods. This results in the outer surface of the steel pipe not being evenly sprayed, with some areas having insufficient coating thickness or missing areas, requiring subsequent touch-up spraying, further increasing the complexity of the process and production costs. In addition, to reduce painting dead zones, the position of the steel pipe needs to be manually adjusted multiple times during some production processes. This is not only cumbersome but also makes it difficult to ensure the consistency and stability of the painting, affecting production efficiency and product quality uniformity.

[0005] In summary, the existing steel pipe painting and drying process suffers from problems such as fragmented processes, low production efficiency, and the tendency to create dead spots during painting. There is an urgent need for an integrated device that can combine the painting and drying processes and improve the uniformity of the paint spraying. Utility Model Content

[0006] In view of the problems existing in the prior art, the present invention provides a steel pipe spray painting and drying integrated machine, which can effectively solve the problems existing in the prior art.

[0007] The technical solution of this utility model is:

[0008] According to one aspect of the present invention, it includes: a water curtain spray booth and a drying room arranged in sequence, wherein the water curtain spray booth and the drying room are connected to each other; it also includes a fixing device for installing steel pipes, wherein the fixing device is movable to the left and right and is arranged between the water curtain spray booth and the drying room, wherein one end of the fixing device is equipped with a first driving device for actuating it.

[0009] The fixing device includes a mounting base, a mounting plate, and at least one support rod. One end of the mounting plate is rotatably mounted on the mounting base, and the other end is fixedly mounted on the support rod. A second driving device for actuating the mounting plate is assembled at one end of the mounting plate. The fixing device also includes at least one fixing member, which is detachably inserted into the end of the support rod. When the steel pipe is sleeved on the outside of the support rod, one end of the steel pipe abuts against the mounting plate, and the other end abuts against the fixing member.

[0010] Furthermore, the fixing member is threadedly connected to the support rod, and at least one end of the fixing member extends outward to form a protrusion.

[0011] Furthermore, it also includes a protective sleeve for shielding the external threads of the support rod, the protective sleeve being fitted onto the end of the support rod, one end of the fixing member extending into the protective sleeve to form a connecting tube, the protective sleeve being threadedly connected to the connecting tube.

[0012] Furthermore, the mounting plate is provided with a plurality of positioning grooves, the support rod is located at the axis of the plurality of positioning grooves, the plurality of positioning grooves are distributed at equal intervals around the outer circumference of the support rod, and the size of the plurality of positioning grooves increases sequentially from the inside to the outside.

[0013] Furthermore, it also includes a positioning element, one end of which is inserted into one of the positioning grooves and the other end of which is inserted into the steel pipe. The outer circumference of the positioning element extends outward to form a boss, and one end of the steel pipe abuts against the boss.

[0014] Furthermore, the number of support rods is provided in multiples, and the multiple support rods are distributed at intervals on the mounting plate.

[0015] Furthermore, the first driving device is a screw slide table, and the water curtain spray booth and drying booth have a notch for the slider of the screw slide table to pass through. It also includes a baffle, one end of which is fixedly connected to the slider of the screw slide table. The fixing device is detachably fixed above the baffle, and the front projection area of ​​the baffle completely covers the fixing device. The baffle partially covers the notch.

[0016] Furthermore, the second driving device is a servo motor, which is mounted on a mounting base, and the output shaft of the servo motor is connected to the connector of the mounting plate.

[0017] By adopting the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:

[0018] Firstly, the water curtain spray booth and drying room are directly connected, and the fixing device can move the steel pipe between the two, eliminating the transfer link between processes, reducing the risk of coating damage and contamination caused by transfer, and significantly improving production efficiency. The fixing device adopts a structure in which the steel pipe is sleeved with a support rod and positioned at both ends, and can rotate with the mounting plate, so that the steel pipe can rotate at a uniform speed during the spraying process, avoiding the dead corners of spraying caused by traditional bracket support or clamp clamping, and greatly improving the uniformity of spraying. The first drive device drives the fixing device to move, realizing the automated connection of the spraying and drying processes, reducing manual intervention and improving production continuity.

[0019] Secondly, the fasteners are threadedly connected to the support rod. This threaded connection facilitates quick disassembly and installation of the fasteners. The position of the fasteners on the support rod can be flexibly adjusted according to the length of the steel pipe, adapting to different specifications of steel pipes and improving the equipment's versatility. The raised structure provides operators with convenient force application points, making it easy to manually tighten the fasteners, simplifying the operation process, saving adjustment time, and improving work efficiency.

[0020] Thirdly, the protective sleeve covers the external threads of the support rod and mates with the connecting pipe threads of the fastener, effectively preventing paint mist generated during the painting process from adhering to the external threads of the support rod. This avoids the paint mist from clogging the threads or affecting the disassembly of the fastener after curing, ensuring the stability and service life of the threaded connection. The threaded fit between the protective sleeve and the connecting pipe further enhances the sealing of the connection between the fastener and the support rod, preventing paint mist from entering the threaded area through the gap, while also protecting the end of the support rod and reducing wear.

[0021] Fourth, the positioning slots on the mounting plate are distributed around the support rod and increase in size. The positioning slots provide suitable installation positions for the positioning parts. Different sizes of positioning slots can correspond to different specifications of positioning parts, thereby adapting to steel pipes with different inner diameters and improving the equipment's compatibility with multiple specifications of steel pipes. The positioning slots are evenly distributed around the support rod to ensure high coaxiality between the positioning parts and the support rod after installation, avoiding eccentric swaying of the steel pipe during rotation and ensuring the stability of painting and drying.

[0022] Fifth, the positioning component works in conjunction with the positioning groove and is equipped with a boss. One end of the positioning component is inserted into the positioning groove, and the other end is inserted into the inside of the steel pipe, which enhances the connection strength between the steel pipe and the mounting plate, prevents the steel pipe from shifting or shaking during rotation, and improves the stability of the fixation. The boss abuts against the end of the steel pipe to prevent the end of the steel pipe from sinking into the positioning groove, ensuring that the outer surface of the end of the steel pipe is completely exposed, eliminating the dead corners for painting caused by the end being blocked, and ensuring the integrity of the coating. The positioning component can be flexibly replaced according to the inner diameter of the steel pipe and, in conjunction with positioning grooves of different sizes, further expands the range of steel pipe specifications that the equipment can adapt to.

[0023] Sixth, multiple support rods are spaced apart on the mounting plate, allowing multiple steel pipes to be painted and dried simultaneously, enabling batch processing and significantly improving production efficiency per unit time to meet the needs of industrialized mass production; the spaced distribution of support rods avoids mutual obstruction between steel pipes, ensuring that each steel pipe can be evenly painted and dried, guaranteeing consistent product quality.

[0024] Seventh, the first drive unit adopts a screw slide table, in conjunction with a notch and a baffle. The screw slide table has high driving precision and stable operation, and can accurately control the movement of the fixed device between the water curtain spray booth and the drying room, ensuring the accuracy of process connection. The baffle covers the fixed device and partially blocks the notch, effectively preventing paint mist in the water curtain spray booth from entering the screw slide table through the notch, avoiding paint mist contamination of the slide table guide rail or affecting its transmission precision, and extending the service life of the slide table. The fixed device can be detachably installed on the baffle, which facilitates equipment maintenance and repair, and reduces later maintenance costs. Attached Figure Description

[0036] Please see Figures 1 to 5The fixing device 3 includes a mounting base 31, a mounting plate 32, and at least one support rod 33. In this embodiment, multiple support rods 33 are provided, and the multiple support rods 33 are spaced apart on the mounting plate 32. One end of the mounting plate 32 is rotatably mounted on the mounting base 31, and the other end is fixed with the support rod 33. A second driving device 6 is assembled on one end of the mounting plate 32 to actuate it. The second driving device 6 is a servo motor, which is mounted on the mounting base 31, and the output shaft of the servo motor is connected to the connector 321 of the mounting plate 32. The servo motor is a direct application of the prior art, and its principle will not be described in detail here. The fixing device 3 also includes at least one fixing member 34, which is detachably inserted into the end of the support rod 33. When the steel pipe C is sleeved on the outside of the support rod 33, one end of the steel pipe C abuts against the mounting plate 32, and the other end abuts against the fixing member 34. The fixing member 34 is threadedly connected to the support rod 33, and at least one end of the fixing member 34 extends outward to form a protrusion 342.

[0037] Please see Figures 1 to 5 It also includes a protective sleeve 35 for shielding the external threads of the support rod 33. The protective sleeve 35 is fitted onto the end of the support rod 33. One end of the fastener 34 extends into the protective sleeve 35 to form a connecting tube 341. The protective sleeve 35 is threadedly connected to the connecting tube 341.

[0038] Please see Figure 4 and Figure 5 The mounting plate 32 is provided with a plurality of positioning grooves 322. The support rod 33 is located at the axis of the plurality of positioning grooves 322. The plurality of positioning grooves 322 are distributed at equal intervals around the outer circumference of the support rod 33, and the size of the plurality of positioning grooves 322 increases sequentially from the inside to the outside.

[0039] Please see Figure 5 and Figure 6 It also includes a positioning element 7, one end of which is inserted into one of the positioning grooves 322, and the other end is inserted into the steel pipe C. Specifically, one end of the positioning element 7 extends into the steel pipe C and is provided with a pin 72, the outer circumferential surface of which matches the inner circumferential surface of the steel pipe C. A boss 71 extends outward from the outer circumferential surface of the positioning element 7, and one end of the steel pipe C abuts against the boss 71. The dimensions of each positioning element 7 are adapted to the dimensions of each positioning groove 322.

[0040] Working principle:

[0041] Steel pipe installation stage: The first drive device (screw slide) drives the fixing device 3 to move to the outside of the drying room 2. At this time, the operator can carry out the installation operation of steel pipe C. Multiple support rods 33 are distributed at intervals on the mounting plate 32 of the fixing device 3, and multiple steel pipes C can be fitted at the same time. According to the inner diameter of the steel pipe C, a suitable positioning part 7 is selected. The positioning part 7 can be used to assist in fixing. The pin 72 of the positioning part 7 is inserted into the inside of the steel pipe C. The protrusion 71 on the outer periphery of the positioning part 7 abuts against the end of the steel pipe C. The other end of the positioning part 7 is inserted into the positioning groove 322 of the corresponding size on the mounting plate 32. The fixing part 34 is threadedly connected to the support rod 33. The protrusion 342 at its end is easy for the operator to tighten. By tightening the fixing part 34, the steel pipe C is fixed. The end of the support rod 33 is fitted with a protective sleeve 35. The connecting pipe 341 of the fixing part 34 is threadedly connected to the protective sleeve 35 to cover the external thread of the support rod 33.

[0042] Painting process stage: After the steel pipe C is installed, the screw slide table drives the fixing device 3 to move to the left and enter the water curtain spray booth 1. The baffle 5 covers part of the gap 4 to reduce paint mist falling into the screw slide table from the gap 4. After the steel pipe C enters the water curtain spray booth 1, the second drive device 6 servo motor drives the mounting plate 32 and support rod 33 to rotate, so that the steel pipe C sleeved on the support rod 33 rotates synchronously. The manual or robotic arm holds the spray gun to spray paint on the outer surface of the rotating steel pipe C. The water curtain spray booth 1 forms a "water curtain" through water flow to absorb the paint mist generated during the painting process.

[0043] Drying process stage: After the painting is completed, the screw slide table drives the fixing device 3 to move to the right and enter the connected drying room 2 from the water curtain spray booth 1. The steel pipe C is dried in the drying room 2 by the heating device (not shown in the figure). The servo motor can continue to drive the steel pipe C to rotate, so that the outer surface of the steel pipe C is heated evenly.

[0044] Finished product unloading stage: After drying is completed, the screw slide table drives the fixing device 3 to move to the outside of the drying room 2. The operator loosens the protective sleeve 35 and the fixing part 34, and removes the dried steel pipe C from the support rod 33, completing a single operation cycle.

[0045] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
