Description

Technical Field

[0001] This utility model relates to the field of spraying equipment technology, and in particular to a guardrail spraying device for FRP guardrail production. Background Technology

[0002] Guardrails, also known as safety railings, are mainly used in residential areas, highways, commercial areas, public places, and other places to protect personal safety and equipment. Guardrails are ubiquitous in our lives. The price per meter of guardrail varies depending on its height. For rust prevention and aesthetic purposes, a protective layer is usually sprayed onto the surface of the guardrail. Powder coating is typically used, where a layer of plastic powder is sprayed onto the surface of the guardrail and then cured at high temperature.

[0003] An existing patent (publication number: CN210675718U) discloses a spraying device for guardrail production. By incorporating a cooling chamber, the surface temperature of the guardrail can be rapidly reduced, facilitating removal by workers and improving work efficiency. A motor drives the spraying chamber to rotate, allowing the spray nozzles within to apply paint more evenly to the guardrail surface. The extension and retraction of a hydraulic piston moves another spray nozzle up and down, which then sprays paint onto both sides of the guardrail. However, in implementing this solution, the following problems were found in the existing technology, which have not been adequately resolved:

[0004] The spraying equipment is used to fix the guardrail with hooks, but the fixation is not secure. When the nozzle is close to the guardrail during spraying, the guardrail is prone to movement, and in severe cases, the guardrail may even fall off, affecting its use. Utility Model Content

[0005] To address the aforementioned problem of guardrails being fixed and stabilized but prone to detachment, this utility model provides a guardrail spraying device for FRP guardrail production.

[0006] This utility model provides a fence spraying device for FRP fence production, which adopts the following technical solution:

[0007] A fence spraying device for FRP fence production includes a conveyor belt, a support column connected to the outer side of the conveyor belt, a spraying chamber provided on the other side of the conveyor belt, a connecting shaft connected to the inner side of the support column, side blocks connected to both sides of the connecting shaft, and a fastening rod connected to the center of the side blocks, the fastening rod being located inside an expansion hole.

[0008] A mounting plate is connected below the edge block, and a winding shaft is connected to both sides of the mounting plate. A tension line is connected below the winding shaft, and a baffle is connected to the other side of the tension line. A return spring is also connected to the outer side of the baffle, and a connecting block is connected below the baffle. A base plate is connected below the connecting block.

[0009] The above technical solution facilitates the use of load-bearing columns and fastening rods to change the position of the load-bearing columns, adapting them to different guardrails. At the same time, the use of mounting plates and baffles ensures a firm fixation. During the spraying process, the guardrail can be loosened by adjusting the tension line so that it is above the base plate, ensuring the spraying effect.

[0010] Optionally, in the above-mentioned FRP fence production fence spraying device, the supporting column and the conveyor belt are integrated and movable, and the two sides of the conveyor belt are connected with connecting gears and driving mechanisms, and the connection between the connecting gears and the conveyor belt is a meshing connection.

[0011] The above technical solution facilitates the use of load-bearing columns and conveyor belts to move the guardrail, thereby enabling automatic mobile spraying.

[0012] Optionally, in the above-mentioned FRP fence production fence spraying device, a drying chamber is also provided on the other side of the spraying chamber, and a cooling chamber is provided on the other side of the drying chamber, and the spraying chamber is a rotatable structure.

[0013] The above technical solution facilitates the integrated spraying, drying, and cooling process by coordinating the spraying chamber, drying chamber, and cooling chamber.

[0014] Optionally, in the above-mentioned FRP fence production fence spraying device, side blocks are symmetrically distributed on both sides of the connecting shaft, the side blocks are connected to the fastening rod in a sliding connection, and the fastening rod is connected to the expansion hole in a sliding connection.

[0015] The above technical solution facilitates the use of connecting shafts and side blocks, allowing for position adjustment of the connecting shafts and ensuring the proper fixing of the guardrail.

[0016] Optionally, in the above-mentioned FRP fence production fence spraying device, the baffle and the mounting plate form a spring reset structure through a reset spring, the baffle and the tension line are installed as an integral part, and the tension line and the winding shaft are connected by a rotatable connection.

[0017] The above technical solution facilitates the cooperation between the baffle and the mounting plate, ensuring that the baffle always fits the guardrail, and the tension line enables automatic tensioning to ensure that the paint is applied to all four sides.

[0018] Optionally, in the above-mentioned FRP fence production fence spraying device, the connection method between the base plate and the mounting plate is hot-melt connection, the connection method between the base plate and the connecting block is hot-melt connection, and the connecting block has a hollow structure.

[0019] The above technical solution facilitates the use of a base plate to support the guardrail, ensuring that it does not fall directly to the ground during spraying.

[0020] In summary, this utility model has at least one of the following beneficial effects:

[0021] By setting a tension line and a return spring inside the mounting plate, the return spring drives the baffle to move toward the center position, thereby limiting and fixing the guardrail at the center position, ensuring that the guardrail will not fall off due to shaking during the spraying process. Secondly, after the spraying is halfway done, the tension line pulls the baffle to open it, thereby spraying the clamping position and avoiding spraying dead corners.

[0022] By having a connecting shaft and a side block installed above the mounting plate, the mounting plate and the connecting shaft can move to change the spacing, thus achieving the purpose of fixing guardrails of different lengths and adapting to different guardrails.

[0028] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0029] Please refer to the attached diagram in the instruction manual. Figure 1-4An embodiment of this utility model is provided: a fence spraying device for FRP fence production, including a conveyor belt 1, a support column 2 connected to the outer side of the conveyor belt 1, and a spraying chamber 3 provided on the other side of the conveyor belt 1. The fence spraying work is completed by spraying through the spraying chamber 3. A connecting shaft 4 is connected to the inner side of the support column 2, and side blocks 5 are connected to both sides of the connecting shaft 4. The side blocks 5 are used to drive the connecting shaft 4 to move, which facilitates subsequent operations. A fastening rod 6 is connected to the center of the side block 5, and the fastening rod 6 is located inside the expansion hole 7.

[0030] A mounting plate 10 is connected to the bottom of the edge block 5. A take-up shaft 14 is connected to both sides of the mounting plate 10. The take-up shaft 14 automatically tightens the tension line 11, thereby automatically loosening the guardrail. The tension line 11 is connected to the bottom of the take-up shaft 14. A baffle 8 is connected to the other side of the tension line 11. The guardrail is fixed by the baffle 8 for easy use. A return spring 9 is also connected to the outside of the baffle 8. A connecting block 13 is connected to the bottom of the baffle 8. A base plate 12 is connected to the bottom of the connecting block 13. The base plate 12 and the connecting block 13 cooperate to support the guardrail and ensure the spraying range.

[0031] Working principle: When in use, first, place the guardrail inside the baffle 8. If the length of the guardrail does not match the distance between the baffles 8 on both sides, pull out the fastening rod 6, release the fixing work of the side block 5, and move the connecting shaft 4 so that the connecting shaft 4 and the side block 5 move, changing the distance between the two baffles 8 until the guardrail can be fixed.

[0032] As described above, after the guardrail is placed between the baffles 8, the conveyor belt 1 drives the support column 2 into the interior of the spraying chamber 3. Then, the spraying chamber 3 starts to rotate and sprays the guardrail. After spraying, the remote control of the winding shaft 14 causes the winding shaft 14 to wind up the tension line 11, thereby tightening the tension on the baffle 8, causing the baffle 8 to move towards the mounting plate 10. At this time, the guardrail falls above the base plate 12, and the winding shaft 14 rotates in the opposite direction, causing the baffle 8 to abut against the top of the guardrail. At this time, the area previously limited by the baffle 8 can be sprayed. After spraying, the guardrail is placed in the drying chamber and cooling chamber for separate processing.

[0033] It should be further explained that the support column 2 and the conveyor belt 1 are integrated and movable. The two sides of the conveyor belt 1 are connected to connecting gears and drive mechanisms, and the connection between the connecting gears and the conveyor belt 1 is a meshing connection. The support column 2 and the conveyor belt 1 work together to drive the guardrail to move, thereby automatically carrying out the mobile spraying work.

[0034] It should be noted that a drying chamber is also provided on the other side of the spraying chamber 3, and a cooling chamber is provided on the other side of the drying chamber. The spraying chamber 3 is a rotatable structure. Through the cooperation of the spraying chamber 3, the drying chamber and the cooling chamber, spraying, drying and cooling are carried out in an integrated manner. For the specific parts of the spraying chamber 3 and the rotating structure, please refer to the corresponding parts in the background art comparative patent.

[0035] It should be noted that there are symmetrically distributed side blocks 5 on both sides of the connecting shaft 4. The side blocks 5 are connected to the fastening rod 6 by a sliding connection, and the fastening rod 6 is connected to the expansion hole 7 by a sliding connection. By using the cooperation between the connecting shaft 4 and the side blocks 5, the position of the connecting shaft 4 can be adjusted to ensure the fixing of the guardrail.

[0036] It should be further explained that the baffle 8 forms a spring return structure with the mounting plate 10 through the return spring 9. The baffle 8 and the tension line 11 are installed as an integral unit. The tension line 11 is connected to the winding shaft 14 by a rotatable connection. Through the cooperation between the baffle 8 and the mounting plate 10, the baffle 8 is always in contact with the guardrail, and the tension line 11 realizes automatic tensioning and loosening, ensuring that the paint is applied to all four sides.

[0037] It should be noted that the connection between the base plate 12 and the mounting plate 10 is a thermoplastic connection, and the connection between the base plate 12 and the connecting block 13 is a thermoplastic connection. The connecting block 13 has a hollow structure and uses the base plate 12 to support the guardrail, ensuring that it will not fall directly to the ground during spraying.

[0038] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
