Description

Technical Field

[0001] The present invention relates to the technical field of lamp pole production, and in particular to lamp pole plastic spraying equipment and a lamp pole plastic spraying system. Background Art

[0002] Powder coating is a surface treatment method in which plastic powder is sprayed onto parts. This process is also commonly referred to as electrostatic powder spraying. Compared to conventional spray painting, this technology offers advantages in advanced technology, energy efficiency, safety, reliability, and vibrant colors. Therefore, it is often used in light industry and home decoration. Its working principle is to charge plastic powder through a high-voltage electrostatic device. Under the influence of the electric field, the coating is sprayed onto the surface of the workpiece. The powder is evenly adsorbed on the surface, forming a powdery coating. After high-temperature baking, the powdered coating solidifies and levels, and the plastic particles melt into a dense, final protective coating with varying effects, firmly adhering to the surface of the workpiece.

[0003] Light poles are formed from carbon steel tubing and often undergo a plastic spraying process to achieve a superior surface protection. However, currently, spraying large light poles is often performed in a paint booth, requiring specialized exhaust gas treatment equipment. Furthermore, plastic particles that do not adhere to the pole surface cannot be recycled. Furthermore, to fully spray the pole, the pole must be flipped 180 degrees on the bracket before spraying the bottom surface.

[0004] Therefore, it is necessary to develop a lamp pole spraying equipment and a lamp pole spraying system to overcome the above-mentioned defects. Summary of the Invention

The lamp pole is erected by supporting the top at both ends to facilitate rotation during the plastic spraying process and to facilitate uniform plastic spraying; the setting of the shield component is adopted to facilitate the centralized recovery of scattered plastic particles.

[0032] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] With reference to the accompanying drawings, Figure 1 This is a schematic diagram of the main structure of the lamp pole spray equipment of the present invention; Figure 2 This is a schematic diagram of the top view of the lamp pole plastic spraying equipment of the present invention; Figure 3 for Figure 1 Schematic diagram of the structure viewed from the middle A direction; Figure 4 for Figure 1 Schematic diagram of the middle BB position structure; Figure 5 It is a schematic cross-sectional view of the guide sleeve assembly of the present invention; Figure 6 It is a schematic structural diagram of the ejection assembly of the present invention; Figure 7 for Figure 6 Schematic diagram of the structure of the middle CC part; Figure 8 This is a top view schematic diagram of the system composition of the lamp pole plastic spraying system of the present invention.

[0035] In one embodiment, Figures 1 to 7As shown, a lamp pole spraying equipment includes a base 1, a driving support 2, a turn clamp 3, a driving unit 4, an intermediate support 5, a top tailstock 7 and a shield assembly. The driving support 2 and the intermediate support 5 are arranged face to face on the base 1, and a shaft sleeve is provided on the driving support 2. The turn clamp 3 is rotatably provided in the shaft sleeve. The driving unit 4 is provided at the bottom of the driving support 2 and can drive the turn clamp 3 to rotate. The top tailstock 7 is provided at the top of the intermediate support 5. The top of the top tailstock 7 is coaxially provided with the turn clamp 3. The lamp pole 21 to be sprayed is horizontally clamped between the inner cone head of the turn clamp 3 and the top of the top tailstock 7 and is coaxially clamped. The bottom end of the lamp pole 21 is a cylindrical opening that can be coaxially supported by the inner cone head of the turn clamp 3. The top of the lamp pole 21 is provided with a coaxial top hole. The top of the top tailstock 7 protrudes forward and can be pushed into the top hole. The top tailstock 7 can use the tailstock on a large lathe. The shield assembly is arranged on the base 1 and between the driving support 2 and the intermediate support 5 and covers the outer periphery of the lamp pole 21. A full-length spray gun opening 16 is provided on one side of the upper portion of the shield assembly. The spray gun opening 16 is used to make way for the plastic powder spray gun that moves axially back and forth.

[0036] The driving unit 4 drives the rotary clamp 3 to rotate, thereby driving the lamp pole 21 to rotate. It is only necessary to spray back and forth along the spray gun opening 16 to complete the full coverage of all surfaces along the entire length by spraying plastic. The lamp pole 21 is clamped by the top of the cone head inside the rotary clamp 3 and the top tailstock 7, which can adapt to the clamping of lamp poles 12 with different diameters. The covering of the periphery of the lamp pole 21 by the shield assembly can form a closed protection, reduce the overflow of plastic powder, protect the working environment, and also facilitate the collection of plastic powder remaining on the inner wall of the shield. The lamp pole spraying equipment of the present invention is convenient for rotation during the spraying process by supporting the lamp pole at both ends, which facilitates uniform spraying. The setting of the shield assembly facilitates the centralized recovery of scattered plastic particles, thereby improving the recycling rate of plastic powder.

[0037] In one embodiment of the present invention, Figures 1 to 3 As shown, the drive support 2 is bolted to the top surface of the base 1. The drive unit 4 includes a reduction motor and a second sprocket 401. The reduction motor is mounted on the bottom plate of the drive support 2 and its working end is connected to the second sprocket 401. The second sprocket 401 is connected to the first sprocket 301 at the rear end of the rotary chuck 3 via a chain. Furthermore, an electrical control box 22 is mounted on the side wall of the drive support 2 to control the operation of the reduction motor.

[0038] Specifically, if Figure 3 and Figure 4As shown, the base 1 includes a base plate 101, footing plates 103, and H-shaped steel columns 105. Two H-shaped steel columns 105 are horizontally mounted below the base plate 101 and connected by segment welding. Multiple footing plates 103 are horizontally welded to the bottom of the H-shaped steel columns 105 to serve as anchor bolt connection plates. The drive support 2 and intermediate support 5 are both mounted on the base plate 101.

[0039] Obviously, the length of the lamp pole 21 to be sprayed ranges from 6 to 12 meters. Therefore, the base 1 has a relatively long length. To reduce the difficulty of processing the base 1, the base 1 can actually be connected by multiple flanges to reduce the length of each group.

[0040] By setting the reduction motor and sprocket transmission method to drive the rotary clamp 3, the rotary clamp 3 can be ensured to rotate stably at a low speed, driving the lamp pole 21 to rotate; by using the H steel column 105 as a supporting component, the total mass of the base 1 can be reduced and sufficient supporting strength can be ensured.

[0041] In one embodiment of the present invention, Figures 1 to 7 As shown, the lamp pole spray equipment of the present invention also includes a pull rod 8, a push-up assembly 9 and a rear support 10. The rear support 10 is installed at the tail end of the base 1 by bolts, and the two pull rods 8 are arranged horizontally and parallel between the driving support 2, the intermediate support 5 and the rear support 10. The pull rods 8 pass through the through holes on the side panels of the driving support 2 and the rear support 10. The two ends of the pull rods 8 are set as threaded rods and locked on both sides of the side panels using end lock nuts 801. The pull rods 8 also pass through the through holes of the side panels of the intermediate support 5. When the pull rods 8 are too long, they can also be connected in series in multiple sections using a threaded connection method. A first guide rail 102 is provided at the top of the base 1 along the length direction, and the first guide rail 102 is parallel to the pull rod 8. The bottom of the intermediate support 5 is guided and connected to the two first guide rails 102 by four ball sliders 104, that is, the intermediate support 5 can move along the first guide rail 102 to adapt to the installation of lamp poles 21 of different lengths. The ejection assembly 9 is arranged at the rear of the intermediate support 5 and is sleeved on the pull rod 8. The ejection assembly 9 can be fixedly connected to the pull rod 8 and push the intermediate support 5 to prevent it from retreating.

[0042] By providing the first guide rail 102 and connecting the intermediate support 5 to the first guide rail 102 via the ball slider 104, the distance between the driving support 2 and the intermediate support 5 can be adjusted to accommodate the installation of lamp poles 21 of different lengths. The provision of the pull rod 8 and the ejection assembly 9 establishes a tensile connection between the driving support 2 and the intermediate support 5, preventing the intermediate support 5 from being pushed backward by the lamp pole 21 during the installation and rotation process, thereby ensuring the installation strength.

[0043] In one embodiment of the present invention, Figure 5As shown, the side plate of the intermediate support 5 is guided by the guide sleeve assembly 6 to slide and connect the pull rod 8. The guide sleeve assembly 6 includes a guide sleeve 601 and a lock nut 602. The middle hole of the guide sleeve 601 is sleeved on the pull rod 8. An external thread section is provided at one end of the guide sleeve 601. The external thread section passes through the through hole of the side plate of the intermediate support 5 and is threadedly connected to the lock nut 602 for axial locking.

[0044] Specifically, if Figure 5 As shown, the guide sleeve 601 and the lock nut 602 are both made of smooth, wear-resistant polytetrafluoroethylene. The outer walls of the guide sleeve 601 and the lock nut 602 are respectively provided with a first wrench hole 6011 and a second wrench hole 6021 for convenient rotation using a hook wrench. There are multiple first wrench holes 6011 and second wrench holes 6021, evenly distributed around the circumference.

[0045] By setting the guide sleeve assembly 6, the side plate of the intermediate support 5 and the pull rod 8 are connected, which can ensure the stability of the top structure of the intermediate support 5; through the cooperation of the guide sleeve 601 and the lock nut block 602, the assembled guide sleeve connection can be realized, which is convenient for replacement and maintenance.

[0046] In one embodiment of the present invention, Figure 6 and Figure 7 As shown, the ejection assembly 9 includes an inner sleeve 901, an outer sleeve 902, a locking ring 903, and an ejection pin 904. The pull rod 8 is radially provided with ejection pin holes 802. Multiple ejection pin holes 802 are evenly spaced throughout the rear half of the pull rod 8. The ejection pin 904 passes through the through hole in the locking ring 903 and the ejection pin holes 802, locking the locking ring 903 in its axial position. One end of the inner sleeve 901 abuts the end face of the locking ring 903 facing the intermediate support 5. The externally threaded section of the inner sleeve 901 connects to the outer sleeve 902, and the end face of the outer sleeve 902 abuts the side wall of the intermediate support 5.

[0047] When it is necessary to push up the side wall of the intermediate support 5, the locking ring 903 is locked in the axial position on the pull rod 8 using the ejection pin 904. Use a hook spanner to watch the third spanner hole 9011 on the inner sleeve 901, and use another hook spanner to rotate the fourth spanner hole 9021 at the end of the outer sleeve 902 outward. The outer sleeve 902 is separated outward from the inner sleeve 901, and the outer end surface of the outer sleeve 902 is pressed against the side wall of the intermediate support 5, applying a pre-tightening force to prevent the intermediate support 5 from moving backward during operation.

[0048] Specifically, if Figure 7As shown, locking ring 903 adopts a half-ring structure and includes a first half-ring 9031 and a second half-ring 9032, which are connected together using a countersunk locking bolt 905. A through hole is defined in the middle of each half-ring 9031 and half-ring 9032, through which an ejector pin 904 is inserted.

[0049] The threaded connection between inner sleeve 901 and outer sleeve 902 allows the length of ejection assembly 9 to be changed. Locking ring 903 is locked to pull rod 8 via ejection pin 904, positioning the rear end of ejection assembly 9. This ensures adequate support for intermediate support 5 and allows for subtle adjustments to the front-to-back position of intermediate support 5. The Huff-shaped locking ring 903 allows for quick installation into the desired position, improving adjustment efficiency.

[0050] In one embodiment of the present invention, Figure 1 and Figure 4 As shown, the shield assembly includes a fixed shield 11 and a movable shield assembly. The first guide rail 102 is not provided in the section of the base 1 near the drive support 2. The fixed shield 11 is positioned between the drive support 2 and the starting end of the first guide rail 102. The upper portion of the fixed shield 11 also needs to be configured to be movable and openable. The movable shield assembly is positioned on the first guide rail 102.

[0051] Specifically, if Figure 1 and Figure 4 As shown, the movable shield assembly includes multiple sets of movable shield brackets 12, shield base plates 13, and top shields 14, which are arranged in a set. The movable shield brackets 12 are supported below the arc-shaped shield base plates 13 and are guided and connected to two first guide rails 102 via four ball sliders 104. The base of the top shield 14 is connected to the pull rod 8 via a collar and is locked in its circumferential position using a shield stop pin 141. A spray gun opening 16 is located between the outer edge of the top shield 14 and the top edge of the shield base plate 13.

[0052] Specifically, if Figure 4 As shown, the lamp pole spray equipment of the present invention also includes an exhaust pipe group 15, which is arranged at the bottom of the fixed protective cover 11 and the movable protective cover combination. A plurality of exhaust holes are opened on the exhaust pipe group 15, and the exhaust pipe group 15 is led out to the negative pressure fan through an air duct at one end close to the driving support 2.

[0053] Specifically, if Figure 4 As shown, the exhaust pipe group 15 is made of multiple layers of hard plastic pipes of different diameters, which can be adaptively telescopically adjusted after the number of complete sets of equipment in the movable shield combination is adjusted and the total length is adjusted, so as to ensure that negative pressure is formed at the bottom of the shield within the entire length of the lamp pole 21 and reduce the overflow of sprayed plastic powder.

[0054] By coordinating the fixed shield 11 and the movable shield assembly, the length of the movable shield assembly can be adaptively adjusted after the length specification of the lamp pole 21 changes, thereby ensuring the versatility of the equipment; by guiding the sliding connection of the movable shield bracket 12 on the first guide rail 102, the position of each set of shields can be flexibly adjusted and quickly adjusted. By setting the exhaust pipe group 15, a negative pressure can be formed at the bottom of the shield to reduce the overflow of plastic powder, while the plastic powder sucked away by the wind can be easily collected and recovered. The exhaust pipe group 15 formed by the nested air duct can be adaptively adjusted in length to ensure uniform ventilation throughout the entire length.

[0055] The working principle of the lamp pole spray equipment of the present invention is as follows: first, adjust the distance between the driving support 2 and the intermediate support 5 according to the length of the lamp pole 21 to be sprayed, that is, push the intermediate support 5 forward and backward along the first guide rail 102 to ensure that the distance between the two is slightly greater than the length of the lamp pole 21. After the position of the intermediate support 5 is initially determined, move the push-up assembly 9 to the rear of the intermediate support 5 and tighten it. Adjust the length of the movable guard assembly so that the fixed guard 11 and the movable guard assembly form a protective cover within the entire length. Then adjust the nesting length of the exhaust pipe group 15 to adapt to the total length. Open the upper part of the fixed guard 11 and all the top guards 14, and hoist the lamp pole 21 that needs to be sprayed into place. Pay attention to horizontal hoisting, with the bottom end facing the inner cone of the turntable 3, and the top of the lamp pole 21 facing the top tailstock 7. Operate the tail handwheel of the top tailstock 7, push the top out, and tighten the two sections of the lamp pole 21 to lock the top. The upper part of the fixed shield 11 is pulled back, and all the top shields 14 are pulled back and locked through the shield limit pin 141. Prepare to enter the plastic spraying process. During the plastic spraying process, the plastic powder spray gun is manually held or gripped by a robot and moves back and forth along the spray gun opening 16. At the same time, the reduction motor drives the lamp pole 21 to rotate to ensure uniform plastic spraying.

[0056] The lamppost spraying equipment of the present invention utilizes a drive unit 4 to rotate the rotary clamp 3, which in turn drives the lamppost 21. Reciprocating spraying along the spray gun opening 16 is all that is needed to achieve full coverage of the entire length of the surface. The lamppost 21 is clamped by the inner cone of the rotary clamp 3 and the top of the top tailstock 7, allowing for clamping of lampposts 12 of varying diameters. The shield assembly covers the periphery of the lamppost 21, creating a closed, protective structure that reduces plastic powder spillage, protects the work environment, and facilitates the collection of plastic powder remaining on the inner wall of the shield. The lamppost spraying equipment of the present invention utilizes a double-ended support structure to facilitate rotation during the spraying process, ensuring uniform spraying. The shield assembly facilitates the centralized recovery of scattered plastic particles, improving the recycling rate of plastic powder. Furthermore, by providing a first guide rail 102, with the intermediate support 5 connected to the first guide rail 102 via a ball slider 104, the distance between the drive support 2 and the intermediate support 5 can be adjusted to accommodate lampposts 21 of varying lengths. By setting the pull rod 8 and the ejection assembly 9, a tension connection can be established between the driving support 2 and the intermediate support 5, preventing the intermediate support 5 from receiving the thrust of the lamp pole 21 and retreating during the installation and rotation process, thereby ensuring the installation strength. By setting the guide sleeve assembly 6, the side plate of the intermediate support 5 and the pull rod 8 are connected, which can ensure the stability of the top structure of the intermediate support 5; through the cooperation of the guide sleeve 601 and the lock nut block 602, an assembled guide sleeve connection can be achieved, which is convenient for replacement and maintenance. The inner sleeve 901 and the outer sleeve 902 of the threaded connection method can change the length of the ejection assembly 9, and the locking ring 903 can be locked on the pull rod 8 by the ejection pin shaft 904, so that the rear end position of the ejection assembly 9 can be positioned, ensuring that the intermediate support 5 receives sufficient support and can slightly adjust the front and rear positions of the intermediate support 5. By adopting the locking ring 903 with a half structure, the locking ring 903 can be quickly installed to the appropriate position, improving the adjustment efficiency. By coordinating the fixed shield 11 and the movable shield assembly, the length of the movable shield assembly can be adaptively adjusted after the length specification of the lamp pole 21 changes, thereby ensuring the versatility of the equipment; by guiding the sliding connection of the movable shield bracket 12 on the first guide rail 102, the position of each set of shields can be flexibly adjusted and quickly adjusted. By setting the exhaust pipe group 15, a negative pressure can be formed at the bottom of the shield to reduce the overflow of plastic powder, while the plastic powder sucked away by the wind can be easily collected and recovered. The exhaust pipe group 15 formed by the nested air duct can be adaptively adjusted in length to ensure uniform ventilation throughout the entire length.

[0057] The present invention also discloses a lamp pole spraying system, which utilizes the lamp pole spraying equipment described in any of the aforementioned embodiments to spray a lamp pole 21. The lamp pole spraying system further includes a manipulator 18, a spraying electrostatic generator, and a dust collector 19. A manipulator base 20 is provided on one side of the base 1. A second guide rail 2001, parallel to the first guide rail 102, is provided on the manipulator base 20. A manipulator slide 17 is provided at the bottom of the manipulator 18. The bottom of the manipulator slide 17 is slidably connected to the second guide rail 2001 via a slider guide. The manipulator 18 holds a spray gun for plastic powder and reciprocates along the spray gun opening 16. The dust collector 19 is positioned adjacent to the drive support 2 and includes a negative pressure fan and a recovery hopper. The recovery hopper is located below the bag filter. The dust collector 19 is connected to the shield assembly via an air duct and is connected to the exhaust port of the exhaust duct assembly 15. The spraying electrostatic generator provides static electricity to the lamp pole 21.

[0058] By providing a robot 18, it is possible to replace manual spraying and perform spraying according to a set program. The robot trajectory, spraying pressure, nozzle direction and other parameters during the spraying process can be controlled, thereby reducing the labor intensity of workers and improving the uniformity of spraying. By providing a dust recovery machine 19, the plastic powder in the exhaust air can be centrally recovered, thereby improving the utilization efficiency of the plastic powder and reducing production costs.

[0059] Obviously, the lamp pole spraying system of the present invention can also be performed using a manual handheld spray gun or a mechanical workbench equipped with a spray gun. Manual operation is flexible and has a low initial investment cost, while the mechanical workbench can reciprocate along a guide rail to spray the plastic and can control the movement speed. These two similar operation methods are equivalent to the lamp pole spraying system of the present invention and therefore fall within the scope of protection of the present invention.

[0060] The embodiments described above are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by persons skilled in the art shall fall within the scope of protection defined by the claims of the present invention.
