Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the field of guardrail post processing technology, and more specifically, to a spraying device for processing guardrail posts. Background Technology
[0002] Guardrail structures are generally divided into main posts and uprights. The main posts are often called main pipes, and the uprights are also called vertical pipes. They are used to support the main pipes. Guardrails are commonly seen in daily life, such as stair railings, balcony railings, bridge railings, etc. During the production process of the uprights, paint is usually sprayed on their surface, so a spraying device is required.
[0003] The existing spraying equipment places the column in the spraying box, fixes the column with clamps, and then sprays the column with the spraying mechanism. However, when the operator removes the column after spraying, the paint surface is easily touched, causing some parts of the paint to be missing.
[0004] The aforementioned spraying device is prone to paint damage when operators remove the column after spraying, resulting in paint loss in some areas and thus reducing the device's effectiveness. Utility Model Content
[0005] To overcome the above-mentioned defects, embodiments of this disclosure provide a spraying device for processing guardrail posts, which solves the technical problem in the prior art where operators easily come into contact with the paint surface when removing the posts after spraying, resulting in partial paint loss.
[0006] According to one aspect, at least one embodiment of the present disclosure provides a spraying device for processing guardrail posts, which includes a processing box, and further includes a drive shaft, a connecting frame, a connecting block, a limiting rod, a limiting frame, a limiting pin, a connecting shaft, a tightening spring, a tightening block, a drive mechanism, and an auxiliary mechanism;
[0007] The drive shaft is rotatably connected inside the processing box. Connecting frames are installed at the inner ends of the two sets of drive shafts. A connecting block is slidably connected inside the connecting frame. A limiting rod passes through the inside of the connecting block, and its outer surface penetrates the connecting frame. A limiting frame is installed at the outer end of the limiting rod. A limiting pin is threaded through the outer side of the limiting frame. One end of the limiting pin, threaded through the limiting frame, is threaded through the connecting frame. The connecting shaft is installed on the inner side of the connecting block. A clamping spring is installed inside the connecting shaft. A clamping block is installed at the outer end of the clamping spring. The drive mechanism is located on the outer side of the processing box, and the auxiliary mechanism is located on the upper surface of the processing box.
[0008] As a preferred embodiment of the spraying device for processing guardrail posts according to this utility model, in order to better dry the posts, the auxiliary mechanism includes a ventilation pipe, a first blocking layer, a second blocking layer, an auxiliary fan, and a heating layer. The ventilation pipe is connected to the upper surface of the processing box. The first blocking layer is installed inside the ventilation pipe. The second blocking layer is installed inside the ventilation pipe. The auxiliary fan is installed inside the ventilation pipe. The heating layer is installed inside the ventilation pipe.
[0009] As a preferred embodiment of the spraying device for processing guardrail posts according to this utility model, in order to better drive the posts to rotate, the driving mechanism includes a support plate, a transmission motor, a first transmission gear and a second transmission gear. The two sets of support plates are installed on the outer side of the processing box. The transmission motor is installed on the upper surface of the support plate. The first transmission gear is installed at the output end of the transmission motor. The second transmission gear is installed on the outer surface of the transmission shaft.
[0010] In a preferred embodiment of the spraying device for processing guardrail posts according to the present invention, in order to better drive the transmission shaft to rotate, the first transmission gear and the second transmission gear mesh, and the number of the first transmission gear and the second transmission gear is two sets.
[0011] As a preferred embodiment of the spraying device for processing guardrail posts according to this utility model, in order to better spray the posts, a support leg is installed on the lower surface of the processing box, and a spraying pipe runs through the back of the processing box.
[0012] As a preferred embodiment of the spraying device for processing guardrail posts according to the present invention, in order to exhaust the hot air generated during the drying process, the outer side of the processing box is connected to an air outlet pipe, the outer end of the air outlet pipe is threaded with a connecting cover, and the outer side of the connecting cover is provided with a ventilation hole.
[0013] In a preferred embodiment of the spraying device for processing guardrail posts according to this utility model, in order to prevent paint droplets from splashing outside, a blocking door is hinged to the front of the processing box, and a movable handle is installed on the front of the blocking door.
[0014] In a preferred embodiment of the spraying device for processing guardrail posts according to the present invention, in order to absorb the paint odor carried in the air, an adsorption bag is provided inside the connecting cover, and multiple sets of activated carbon blocks are provided inside the adsorption bag.
[0015] The beneficial effects of the embodiments disclosed herein are as follows:
[0016] In this disclosure, the column is fixed by fitting it onto the outer surface of the clamping block and by the reaction force of the clamping spring. Then, the connecting block is slid into the connecting frame. Compared with the prior art of directly placing the column on the fixed frame, this device can separate the connecting block from the connecting frame after spraying, reducing the number of times the operator directly contacts the column.
[0017] In this disclosure, an auxiliary fan carries away the heat generated by the heating layer through the air to dry the columns inside the processing box. Compared with the direct removal and placement of columns in the prior art, this device allows operators to remove and place the columns after the paint on the surface has set, which can prevent the operators from directly removing the columns after they have been sprayed and avoid missing paint on the surface of the columns.

Therefore, they should not be construed as limitations on this disclosure.
[0029] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0030] like Figures 1-4 As shown, it illustrates a spraying device for processing guardrail posts according to an embodiment of the present disclosure, which includes a processing box 1, a transmission shaft 2, a connecting frame 3, a connecting block 4, a limiting rod 5, a limiting frame 6, a limiting pin 7, a connecting shaft 8, a top-tightening spring 9, a top-tightening block 10, a drive mechanism, and an auxiliary mechanism.
[0031] like Figure 3As shown, the drive shaft 2 is rotatably connected inside the processing box 1. The inner ends of the two sets of drive shafts 2 are equipped with connecting frames 3. The connecting blocks 4 are slidably connected inside the connecting frames 3. The limiting rod 5 passes through the inside of the connecting blocks 4. During the rotation of the connecting blocks 4, the limiting rod 5 restricts the connection and prevents the connecting blocks 4 from slipping out of the connecting frames 3. The outer surface of the limiting rod 5 passes through the connecting frames 3. The outer end of the limiting rod 5 is equipped with a limiting frame 6. The outer side of the limiting frame 6 is threaded through a limiting pin 7. One end of the limiting pin 7, which is threaded through the limiting frame 6, is threaded through the connecting frame 3. The connecting shaft 8 is installed on the inner side of the connecting blocks 4. The connecting shaft 8 is equipped with a clamping spring 9. The outer end of the clamping spring 9 is equipped with a clamping block 10. When in use, the clamping block 10 needs to be inserted into the column so that the clamping block 10 contacts the inner wall of the column. The outer end of the column contacts the inner side of the connecting block 4. Therefore, the column will not deviate during rotation. The drive mechanism is located on the outer side of the processing box 1, and the auxiliary mechanism is located on the upper surface of the processing box 1.
[0032] like Figure 4 As shown, the auxiliary mechanism includes a ventilation duct 11, a first barrier layer 12, a second barrier layer 13, an auxiliary fan 14, and a heating layer 15. The ventilation duct 11 is connected to the upper surface of the processing box 1. The first barrier layer 12 is installed inside the ventilation duct 11. The second barrier layer 13 is installed inside the ventilation duct 11. Both the first barrier layer 12 and the second barrier layer 13 have a blocking mesh installed inside. The blocking mesh in the second barrier layer 13 is made of metal to prevent hot air from blowing away the blocking mesh at the bottom. The mesh openings of the bottom blocking mesh are larger than those of the top blocking mesh to facilitate the first barrier layer 12 in blocking dust. The auxiliary fan 14 is installed inside the ventilation duct 11. The heating layer 15 is installed inside the ventilation duct 11. The heating layer 15 consists of a fixing plate and a heating wire. The heating wire is controlled to start and stop by an external single-control switch and requires an external power supply. The auxiliary fan 14 is also controlled to start and stop by an external single-control switch and requires an external power supply.
[0033] like Figure 3 As shown, the drive mechanism includes a support plate 16, a transmission motor 17, a first transmission gear 18, and a second transmission gear 19. Two sets of support plates 16 are installed on the outer side of the processing box 1. The transmission motor 17 is installed on the upper surface of the support plate 16. The transmission motor 17 is controlled to start and stop by an external single-control switch. The transmission motor 17 requires an external power supply. The transmission motor 17 is a common geared motor on the market, so the rotation speed of the column is not very fast. The two sets of transmission motors 17 located on the left and right sides are in the forward and reverse rotation states, respectively. The first transmission gear 18 is installed at the output end of the transmission motor 17. The second transmission gear 19 is installed on the outer surface of the transmission shaft 2. The first transmission gear 18 and the second transmission gear 19 mesh. There are two sets of both the first transmission gear 18 and the second transmission gear 19.
[0034] like Figure 1 and Figure 2 As shown, a support leg is installed on the lower surface of the treatment box 1. A spray pipe 24 runs through the back of the treatment box 1. One end of the spray pipe 24 extending out of the treatment box 1 is connected to the output end of an external paint pump. An air outlet pipe 20 is connected to the outer side of the treatment box 1. A connecting cover 21 is threaded onto the outer end of the air outlet pipe 20. A ventilation hole is provided on the outer side of the connecting cover 21 to exhaust the air inside the treatment box 1. A blocking door 22 is hinged to the front of the treatment box 1. A movable handle 23 is installed on the front of the blocking door 22. An adsorption bag is installed inside the connecting cover 21. Multiple sets of activated carbon blocks are installed inside the adsorption bag. The diameter of the ventilation hole is smaller than the diameter of the adsorption bag. Therefore, when air passes through the inside of the air outlet pipe 20, the adsorption bag will not be blown out by the air along the ventilation hole.
[0035] In this embodiment, the column is moved to the outer side of the clamping block 10, so that the clamping block 10 contacts the inside of the column and moves inward. This inward movement is centered on the connecting shaft 8. The clamping block 10 moves inward and compresses the clamping spring 9. The reaction force of the clamping spring 9 clamps the column, so that the outer end of the column contacts the connecting block 4.
[0036] Manipulate the movable handle 23 to open the blocking door 22 by flipping it upward along the processing box 1 via the hinge. Manipulate the connecting block 4 to slide into the connecting frame 3. Manipulate the limiting frame 6 to move to the outside of the connecting frame 3. Manipulate the limiting frame 6 to move inward, which will drive the limiting rod 5 to move inward. This inward movement is centered on the connecting frame 3. The inward movement of the limiting frame 6 will drive the limiting rod 5 to move inward. The limiting rod 5 will move inward, pass through the connecting frame 3, and insert into the connecting block 4, so that the limiting frame 6 contacts the connecting frame 3. Manipulate the limiting pin 7 to pass through the limiting frame 6 and insert into the connecting frame 3. Then rotate the limiting pin 7 clockwise to fix the limiting frame 6 to the outside of the connecting frame 3.
[0037] Manipulate the movable handle 23 to flip the blocking door 22 downwards and close it. The spray pipe 24 transmits paint to its interior through the external paint pump, so that the paint is sprayed out along the spray pipe 24 to spray the column. Start the drive motor 17 (the drive motors 17 on the left and right sides rotate forward and reverse respectively). The output end of the drive motor 17 rotates and drives the first drive gear 18 to rotate. The first drive gear 18 rotates and meshes with the second drive gear 19 to rotate. The second drive gear 19 rotates and drives the drive shaft 2 to rotate. The drive shaft 2 rotates and drives the connecting frame 3 to rotate. The connecting frame 3 rotates and drives the connecting block 4 to rotate. The connecting block 4 rotates and drives the connecting shaft 8 to rotate. The column rotates through the clamping block 10 and the clamping spring 9.
[0038] After the coating is applied, the heating layer 15 is powered on to heat up, and the auxiliary fan 14 is started. The output end of the auxiliary fan 14 rotates to draw air into the ventilation pipe 11. The air passes through the first barrier layer 12 to block the dust in the air. The air passes through the heating layer 15 to carry away the heat. The air is discharged along the ventilation pipe 11 to dry the column. The air carrying odor enters the air outlet pipe 20, passes through the adsorption bag to adsorb the odor, and the air is finally discharged along the ventilation hole.
[0039] After drying for a period of time, operate the moving handle 23 to flip the blocking door 22 upward along the processing box 1 via the hinge, loosen the limit pin 7 counterclockwise, operate the limit frame 6 to pull the limit rod 5 out of the connecting block 4 along the connecting frame 3, operate the connecting block 4 to slide out along the inside of the connecting frame 3, keep it in this state and take the column to air dry naturally. Replacing the connecting block 4 can prevent the operator from accidentally touching the paint.
[0040] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
