Description

Technical Field

[0001] The utility model relates to the technical field of staircase handrail production, in particular to a high-temperature spraying line for staircase handrails. Background Technique

[0002] A staircase handrail is a support rod for a staircase guardrail. When producing the profiles used for staircase handrails, a high-temperature spraying device is required to spray an anti-rust layer on the surface of the profiles. High-temperature spraying refers to a series of processes in which fine and dispersed coating materials are deposited on the surface of a prepared substrate in a molten or semi-molten state to form a certain spraying deposit layer.

[0003] In the patent application with the authorization publication number CN214515538U, the authorization publication date of October 29, 2021, and the name of "A Vertical Spraying Line for Aluminum Profiles", a plurality of chambers are arranged inside the base and are respectively embedded with a driving motor, a booster pump and a heating component. A dust box is arranged at the top of one side of the base. From one side to the other side of the top of the base, a dust removal box, a spraying box and a drying box are fixedly installed in sequence. A conveying device is arranged through the interiors of the dust removal box and the drying box. This vertical spraying line for aluminum profiles is provided with a rotating fixture to assist the conveying device to adjust and clamp according to the model of each aluminum profile to be processed. A dust removal box is provided to completely suck and remove the impurities on the surface of the aluminum profile to be processed, ensuring that the subsequent spraying process is more perfect; a linear guide rail motor is provided to assist the spray head to spray the surface of the clamped aluminum profile carefully and comprehensively, and the rotating disk provided by the rotating fixture drives the aluminum profile to rotate; a drying box is provided to assist the just-sprayed aluminum profile to carry out the drying process, so as to ensure the rapid setting of the spraying material on the surface of the aluminum profile.

[0004] When the existing spraying line is in use, although the impurities on the surface of the profile can be sucked out through the arranged dust removal box, it is found in use that due to the strong adhesion of some impurities, the impurities on the surface of the profile cannot be effectively removed by simple suction, and the cleaning strength is weak. Furthermore, the adhesion of the subsequent sprayed coating is poor, and the impurities on the surface of the profile cannot be effectively removed. Therefore, we propose a high-temperature spraying line for staircase handrails to solve the problems raised above. Content of the Utility Model

[0015] 3. Beneficial effects:

[0016] Adopting the technical solutions provided by the utility model, compared with the prior art, the high-temperature spraying line for staircase handrails of the utility model has the following specific contents:

[0017] (1) The profile is conveyed by a conveying device, passing through the inside of the box through the material passing port. At the same time, the profile passes through the inside of the annular pipe. The motor drives the driving wheel to rotate. When the driving wheel rotates, the U-shaped frame is driven to reciprocate horizontally through the transmission member. Furthermore, the U-shaped frame drives the annular pipe to reciprocate horizontally. The annular pipe contacts the surface of the profile through the brush. Before the profile enters the spraying tank, the surface of the profile is cleaned by the reciprocating annular pipe and the brush. The fan works to generate negative pressure in the negative pressure pipe, and then the suction head generates suction to suck out the impurities cleaned from the surface of the profile, effectively improving the cleaning effect of the profile so that the profile can enter the spraying tank for spraying, thereby effectively improving the spraying effect.

[0018] (2) When the hydraulic rod drives the lifting frame to move downward, the lifting frame drives the two sliding seats to move away from each other through the transmission rod, and the sliding seats drive the two limiting wheels to move away from each other. When the hydraulic rod drives the lifting frame to move upward, it can drive the two limiting wheels to move closer to each other. Furthermore, the distance between the two limiting wheels can be adjusted by a single hydraulic rod, so that the two limiting wheels abut against both sides of the profile, thereby being able to guide profiles of different sizes and preventing the profile from shifting during movement.

[0028] Please refer to Figures 1 to 4 , a high-temperature spraying line for staircase handrails, comprising a box body 1. Dust removal grooves 2 and spraying grooves 3 are respectively formed in the inner parts on both sides of the box body 1. The dust removal groove 2 and the spraying groove 3 are isolated by a partition plate 4. Among them,

[0029] Both the middle parts at the two ends of the box body 1 and the middle part of the partition plate 4 are provided with material passing openings 5. Inside the spraying tank 3 corresponding to the material passing openings 5, an annular frame 6 is installed. Inside the annular frame 6, spraying guns 7 are equidistantly installed. Outside the box body 1 corresponding to the material passing openings 5, a guiding mechanism is provided. Inside the dust removal tank 2 near the upper part, a fixing frame 15 is installed. In the middle of the fixing frame 15, a sliding groove 16 is opened. Inside the sliding groove 16, a sliding block 17 is arranged. At the bottom end of the sliding block 17 corresponding to the material passing opening 5, an annular pipe 18 is installed. Inside the inner wall of the annular pipe 18, dust suction heads 19 are equidistantly communicated. On the inner walls of both sides of the annular pipe 18 near the dust suction heads 19, brushes 20 are installed;

[0030] At the top of the sliding block 17, a U-shaped frame 21 is fixedly connected. Inside the dust removal tank 2 corresponding to the inner top of the fixing frame 15, a motor 22 is installed. At the shaft end of the motor 22, a transmission wheel 23 is installed. At the bottom of the U-shaped frame 21 corresponding to the transmission wheel 23, a transmission part 24 is fixedly connected. On the top of the box body 1, a blower 25 and a filter box 26 are symmetrically installed. The blower 25 is connected to the filter box 26 through an air inlet pipe 27. One end of the blower 25 is communicated with a negative pressure pipe 28. The bottom end of the negative pressure pipe 28 is connected to the annular pipe 18 through a flexible pipe 29. Inside the spraying tank 3, a negative pressure hood 30 is installed. The negative pressure hood 30 is connected to the negative pressure pipe 28 through a connecting pipe 31;

[0031] The profile is conveyed by a conveying device, so that the profile passes through the inside of the box body 1 through the material passing opening 5. At the same time, the profile passes through the inside of the annular pipe 18. The motor 22 drives the transmission wheel 23 to rotate. When the transmission wheel 23 rotates, the U-shaped frame 21 is driven to move horizontally back and forth through the transmission part 24. Then, the U-shaped frame 21 drives the annular pipe 18 to move horizontally back and forth. The annular pipe 18 contacts the surface of the profile through the brushes 20. Before the profile enters the spraying tank 3, the surface of the profile is cleaned by the reciprocating annular pipe 18 and the brushes 20. When the blower 25 works, negative pressure is generated in the negative pressure pipe 28. Then, suction force is generated in the dust suction heads 19, and the impurities cleaned from the surface of the profile are sucked out, effectively improving the cleaning effect of the profile, so that the profile can enter the spraying tank 3 for spraying, and thus effectively improving the spraying effect.

[0032] Please refer to Figures 1 to 4, the guiding mechanism includes a sliding seat 8. The outer walls on both sides of the box body 1 near the material passing port 5 are symmetrically and slidably provided with sliding seats 8. The bottom of the sliding seat 8 is rotatably connected with a limiting wheel 11. A hydraulic rod 12 is installed on the outer side of the box body 1 above the material passing port 5. The bottom end of the hydraulic rod 12 is fixedly connected with a lifting frame 13. The two sides of the lifting frame 13 are symmetrically and rotatably connected with transmission rods 14. One end of the transmission rod 14 far from the lifting frame 13 is rotatably connected with the top of the sliding seat 8. A sliding groove 9 is formed in the outer side of the box body 1 corresponding to the sliding seat 8. One side of the sliding seat 8 corresponding to the sliding groove 9 is fixedly connected with a sliding block 10. When the hydraulic rod 12 drives the lifting frame 13 to move downward, the lifting frame 13 drives the two sliding seats 8 to move away from each other through the transmission rods 14, so that the sliding seat 8 drives the two limiting wheels 11 to move away from each other. When the hydraulic rod 12 drives the lifting frame 13 to move upward, it can drive the two limiting wheels 11 to move closer to each other. Furthermore, the distance between the two limiting wheels 11 can be adjusted by a single hydraulic rod 12, so that the two limiting wheels 11 abut against both sides of the profile, and thus the profiles of different sizes can be guided to prevent the profiles from shifting during movement.

[0033] Please refer to Figures 1 to 4 , the sliding groove 16 is arranged parallel to the short side of the fixed frame 15, and the sliding groove 16 is perpendicular to the U-shaped frame 21. The transmission part 24 is located at the bottom of the side of the transmission wheel 23, and the transmission part 24 is a cylinder, and the outer diameter of the transmission part 24 matches the inner width of the U-shaped frame 21. When the transmission wheel 23 rotates, it will drive the transmission part 24 to move accordingly. Since the transmission part 24 is inside the U-shaped frame 21, the transmission wheel 23 can drive the U-shaped frame 21 to reciprocate horizontally through the transmission part 24, and then the U-shaped frame 21 drives the annular pipe 18 to reciprocate through the sliding block 17.

[0034] Working principle: When using this high-temperature spraying line for staircase handrails, as Figures 1 to 4As shown in the figure, first, the profile is conveyed by a conveying device, so that the profile passes through the inside of the box body 1 through the material passing port 5, and at the same time, the profile passes through the inside of the annular pipe 18. The motor 22 drives the driving wheel 23 to rotate. When the driving wheel 23 rotates, it drives the U-shaped frame 21 to move horizontally back and forth through the transmission member 24. Further, the U-shaped frame 21 drives the annular pipe 18 to move horizontally back and forth. The annular pipe 18 contacts the surface of the profile through the brush 20. Before the profile enters the spraying tank 3, the surface of the profile is cleaned by the reciprocating annular pipe 18 and the brush 20. The fan 25 works to generate negative pressure in the negative pressure pipe 28, and further, the suction head 19 generates suction to suck out the impurities cleaned from the surface of the profile, effectively improving the cleaning effect of the profile, so that the profile can enter the spraying tank 3 for spraying, and further effectively improving the spraying effect. After the profile enters the spraying tank 3, it passes through the inside of the annular frame 6. Through the spraying gun 7 arranged in the annular frame 6, the coating material is sprayed onto the surface of the profile. When the hydraulic rod 12 drives the lifting frame 13 to move downward, the lifting frame 13 drives the two sliding seats 8 to move away from each other through the transmission rod 14, so that the sliding seats 8 drive the two limiting wheels 11 to move away from each other. When the hydraulic rod 12 drives the lifting frame 13 to move upward, it can drive the two limiting wheels 11 to move closer to each other. Further, the distance between the two limiting wheels 11 can be adjusted by a single hydraulic rod 12, so that the two limiting wheels 11 abut against both sides of the profile, and further, profiles of different sizes can be guided to prevent the profile from shifting during movement.
