Description

Technical Field

[0001] The utility model relates to the technical field of guardrail spraying processing, in particular to a spraying device for corrosion-resistant zinc steel guardrails. Background Art

[0002] Zinc steel guardrail refers to the balcony guardrail made of zinc alloy material. Due to its advantages of high strength, high hardness, exquisite appearance and bright color, it has become the mainstream product used in residential areas. It is mainly made by welding zinc steel support rods one by one. Before welding, in order to ensure the service life of the guardrail, it is generally necessary to use a colored polymer imitation enamel electrophoresis high temperature curing process on its surface to form an anti-corrosion protective layer;

[0003] Chinese patent authorization announcement number CN211964721U discloses an electrostatic spraying device for zinc steel guardrail production, including a spray box, a housing, a second motor, a first mounting frame, a second mounting frame, a first motor, a rotating shaft, a screw rod, a slider, a spray mechanism and a spray gun. The first mounting frame and the second mounting frame are both rotatably connected inside the spray box and driven by the second motor, and the ball nut pair is sleeved on the outside of the screw rod. The spray mechanism is arranged at the bottom of the slider, and the spray gun is connected to the output end of the spray mechanism. The utility model sprays the surface of the guardrail from top to bottom, cooperates with gravity, saves resources, and ensures the spraying effect. The above-mentioned prior art solution has the following shortcomings: the spraying device mainly uses the second motor to change the first mounting frame for rotation, so that the spray gun can evenly spray the surface of the zinc-steel guardrail. However, the spray gun moves horizontally during the rotation of the zinc-steel guardrail, that is, the spray gun first sprays a certain side of the zinc-steel guardrail, and then moves directly to the right, thereby driving the zinc-steel guardrail to rotate. However, the other side of the previous position cannot be guaranteed to be sprayed, which can easily cause certain spray leaks and affect the uniformity of the coating. Therefore, there is room for improvement. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-Figure 5 The utility model provides an embodiment: a spraying device for corrosion-resistant zinc steel guardrail, comprising a spraying platform 1, guide plates 2 are installed on both sides of the top of the spraying platform 1, and a storage box 14 is connected to one side of the top of the two guide plates 2, and an outlet 15 is opened at the bottom of the storage box 14;

[0025] The thickness of the outlet 15 matches the thickness of the zinc steel guardrail support rod, and the length of the outlet 15 matches the length of the zinc steel guardrail support rod;

[0026] Specifically, Figure 4 As shown, when in use, the storage box 14 and the outlet 15 are used to centrally store the zinc steel guardrail support rods, thereby reducing the operation of loading the zinc steel guardrail support rods one by one and improving the convenience of spraying processing;

[0027] A guide hole 3 is provided inside the guide plate 2, and the guide hole 3 is located on one side of the outlet 15. Two relatively arranged fixed blocks 10 are installed on the side of the top of the spraying station 1 away from the storage box 14, and an electric telescopic rod 4 is installed on the side of the fixed block 10 close to the storage box 14. A connecting block 5 is installed at one end of the electric telescopic rod 4, and a drying lamp 8 is connected between the two connecting blocks 5. At the same time, the drying lamp 8 runs through the inside of the two guide holes 3. A movable seat 6 is installed on one side of the connecting block 5, and an adjustable clamping mechanism 7 is provided inside the movable seat 6.

[0028] The adjustable clamping mechanism 7 includes a rotating shaft 703 that passes through the interior of the movable seat 6, and one end of the rotating shaft 703 passes through the interior of the guide hole 3 and is installed with a clamping block 704, an electromagnet 705 is arranged inside the clamping block 704, and the other end of the rotating shaft 703 is installed with a gear 701, and a toothed plate 702 is evenly installed on the top of the spraying table 1 below the gear 701;

[0029] There are four sets of tooth plates 702, and the number of teeth of the tooth plates 702 is one-fourth of the number of teeth of the gear 701. When the tooth plates 702 are meshed with the gear 701, the gear 701 can be driven to rotate 90°.

[0030] The position of the tooth plate 702 is closer to the guide plate 2 than the inverted U-shaped support frame 9, the tooth plate 702 and the inverted U-shaped support frame 9 are staggered and distributed at equal intervals, and the spacing between the two clamping blocks 704 is adapted to the length of the zinc steel guardrail support rod;

[0031] Specifically, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, when in use, the electromagnet 705 is used to increase the stability of the clamping block 704 on the zinc steel guardrail support rod, and the mutual meshing between the gear 701 and the tooth plate 702 is used to ensure that the zinc steel guardrail support rod is rotated and turned over during the spraying process to improve the spraying uniformity of the side of the zinc steel guardrail support rod;

[0032] One end of the adjustable clamping mechanism 7 passes through the guide hole 3 and extends to the inner side of the guide plate 2. At the same time, the positions of the two adjustable clamping mechanisms 7 pass through the central axis of the storage box 14 and are symmetrically distributed. The top of the spraying station 1 is evenly installed with an inverted U-shaped support frame 9, and the top of the inverted U-shaped support frame 9 is installed with a paint box 11. The bottom of the paint box 11 is installed with a spray gun 12, and the bottom end of the spray gun 12 faces the top of the spraying station 1. The outside of the spray gun 12 is provided with a self-starting mechanism 13;

[0033] The self-starting mechanism 13 includes a solenoid valve 1301 installed on the outside of the spray gun 12, and one end of the solenoid valve 1301 is connected to the external power supply circuit through the wire 1302. The solenoid valve 1301 is routed along the inside of the inverted U-shaped support frame 9. The solenoid valve 1301 is divided and disconnected by two metal sheets 1303. A metal ring 1304 is installed on the outside of the gear 701. During the rotation of the rotating shaft 703, when the metal ring 1304 and the metal sheet 1303 are attached to each other, the solenoid valve 1301 is powered on to start the spray gun 12.

[0034] There are multiple groups of metal sheets 1303, and each group is provided with two metal sheets. At the same time, the two metal sheets 1303 are distributed up and down on the inner wall of the inverted U-shaped support frame 9, and the distance between the two metal sheets 1303 is adapted to the diameter of the metal ring 1304;

[0035] Specifically, Figure 1 , Figure 2 and Figure 3 , Figure 5 As shown, when in use, the metal ring 1304 and the metal sheet 1303 are used to cooperate with each other, so that when the two are in contact, the electromagnetic valve 1301 is started and opened, thereby realizing the automatic spraying start operation of the spray gun 12, reducing manual control and avoiding waste of paint.

[0036] Working principle: When the utility model is used, firstly, the zinc steel guardrail support rods are placed one by one inside the storage box 14, so that the zinc steel guardrail support rods are stacked up and down and the bottom end is moved to the top of the spraying station 1 through the outlet 15, and the zinc steel guardrail support rods are clamped by the left and right clamping blocks 704, and the stable connection between the tooth plate 702 and the zinc steel guardrail support rod is ensured by the action of the electromagnet 705;

[0037] Secondly, start the electric telescopic rod 4 to shorten, so that it pulls the moving seat 6 to move to the right through the connecting block 5, and then the rotating shaft 703 drives the zinc steel guardrail support rod to move synchronously, so that the zinc steel guardrail support rod first moves to the lower end of the first inverted U-shaped support frame 9, and at this time the metal ring 1304 and the metal sheet 1303 contact each other, so that the wire 1302 connects the solenoid valve 1301 with the external power supply to start the spray gun 12 to open, so that the spray gun 12 sprays the paint inside the paint box 11 to one side of the zinc steel guardrail support rod. When the spraying is completed, continue to start the electric telescopic rod 4 to shorten, and in the process again, the metal ring 1304 separates from the metal sheet 1303, so that the spray gun 12 is closed;

[0038] Finally, during the continuous rightward movement of the moving seat 6, the gear 701 and the tooth plate 702 contact and mesh with each other. Since the position of the tooth plate 702 is fixed, the gear 701 rotates 90°, so that the gear 701 drives the rotating shaft 703 to rotate synchronously, and the clamping block 704 drives the zinc-steel guardrail support rod to rotate and turn over, so that the sprayed surface faces the drying lamp 8. In this process, the drying lamp 8 is started synchronously to dry the sprayed surface. In the process of rotation, the block 16 is moved to the inside of the slot 17 and the block 16 is engaged with the slot 17 at the next position to achieve automatic locking after the rotating shaft 703 rotates 90°. This reciprocating process is repeated under the action of multiple groups of spray guns 12 to achieve the effect of spraying the four sides of the zinc-steel guardrail support rod one by one, thereby improving its uniformity.
