Description

Technical Field

[0001] This invention relates to the field of fiberglass spraying technology, and more particularly to a spraying device and method for fiberglass sheet surfaces. Background Technology

[0002] Fiberglass, or fiber reinforced plastic, generally refers to reinforced plastics that use glass fiber to reinforce unsaturated polyester, epoxy resin, and phenolic resin matrices, with glass fiber or its products as reinforcing materials. After the fiberglass sheets are manufactured, they need to be sprayed with paint using a spraying device to improve the quality of the fiberglass.

[0003] There are many types of fiberglass sheets. When irregularly shaped sheets are needed, the distance between the nozzle and the sheet changes, which can result in some areas being sprayed too thickly or too thinly. At the same time, dust on the sheet can also affect the thickness of the coating, thus affecting the spraying quality. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a spraying device and method for coating fiberglass sheets.

[0005] The present invention solves the above-mentioned technical problems through the following technical means:

[0006] A fiberglass sheet surface spraying device includes a base, a sliding seat, and an adjustment mechanism. The sliding seat is located above the base. The adjustment mechanism includes a cleaning rod located below the sliding seat. Two sets of shock-absorbing casters are installed at the bottom of the cleaning rod. An inner telescopic rod is fixedly connected to the top of the cleaning rod. A spray nozzle is connected to the bottom of the inner telescopic rod and is rotatably connected to the top wall of the cleaning rod. A telescopic spring is sleeved on the outer wall of the inner telescopic rod. The top of the telescopic spring is fixedly connected to the bottom of the inner telescopic rod. Outer telescopic rods are provided at both ends of the telescopic spring and are fixedly connected to the bottom of the sliding seat.

[0007] Preferably, two sets of connecting plates are fixedly connected to the top of the base, and two sets of slotted support rods are fixedly connected to the inner sidewall of the connecting plates. An electric trolley is slidably connected inside the slotted support rod, and one side of the electric trolley is fixedly connected to both ends of the sliding seat.

[0008] Preferably, a servo motor is installed on one side of the electric trolley, and a threaded rod is fixedly connected to the output end of the servo motor. The outer wall of the threaded rod is rotatably connected to the outer wall of the sliding seat. Moving slots are provided on both the upper and lower sides of the sliding seat. A sliding ink bladder is movable inside the moving slot, and the bottom end of the sliding ink bladder communicates with the top end of the inner telescopic rod.

[0009] Preferably, a sliding rotating block is fixedly sleeved on the top of the cleaning rod, and a contact ring is fixedly connected to the top of the sliding rotating block, with the top of the contact ring contacting the bottom of the outer telescopic rod.

[0010] Preferably, a plurality of teeth are fixedly connected to one side of the outer telescopic rod, and a gear meshes with one side of the teeth. The gear is fixedly connected to the top of the cleaning rod, and the gear is rotatably connected to the outer side wall of the inner telescopic rod.

[0011] Preferably, a conveyor belt is installed on the surface of the base, fixing blocks are fixedly connected to both sides of the sliding ink sac, the fixing blocks and the threaded rod are threadedly connected to each other, a cover is installed on the top of the sliding ink sac, and the outside of the sliding ink sac is made of rubber.

[0012] Preferably, the outer wall of the sliding ink sac is provided with an anti-clogging mechanism, which includes an electromagnetic acceleration ring, a sliding track, and ball bearings.

[0013] Preferably, the sliding track is fixedly connected to the outer wall of the sliding ink cartridge, and a number of electromagnetic acceleration rings are fixedly connected to the outer wall of the sliding track. A ball bearing moves inside the sliding track, and one end of the ball bearing contacts the outer wall of the sliding ink cartridge.

[0014] The method for spraying fiberglass sheet surfaces includes the following steps:

[0015] S1: Preparation steps: Fix the irregularly shaped fiberglass sheet inside the base, adjust the sliding ink bladder to the edge of the irregularly shaped fiberglass sheet using an electric trolley, and prepare to spray the irregularly shaped fiberglass sheet.

[0016] S2: Moving steps: Start the electric trolley to drive the sliding seat to move intermittently laterally inside the slotted support rod. At the same time, start the servo motor to drive the sliding ink bag to reciprocate inside the moving slot, thereby driving the telescopic spring, inner telescopic rod and printhead to move through the sliding ink bag.

[0017] S3: Cleaning and spraying steps. When the telescopic spring moves, it drives the gear to move, causing the gear teeth to rotate. The rotation of the gear drives the brush at the bottom of the cleaning rod to rotate, thereby cleaning the surface of the irregular fiberglass sheet and preventing dust from affecting the spraying effect. At the same time, the outer telescopic rod, telescopic spring and inner telescopic rod assist the cleaning rod in adjusting its height to follow the surface of the irregular fiberglass sheet, so that the spray head is kept at a fixed distance from the surface of the irregular fiberglass sheet, thereby avoiding the phenomenon of excessive or insufficient local spraying and improving the spraying quality.

[0018] The beneficial effects of this invention are as follows: When the nozzle needs to spray an irregularly shaped fiberglass sheet, the cleaning rod is used to clean the surface of the irregularly shaped fiberglass sheet to prevent dust from affecting the spraying effect. At the same time, the adjusting mechanism is used to assist the cleaning rod in adjusting its height to follow the surface of the irregularly shaped fiberglass sheet, so that the nozzle maintains a fixed distance from the surface of the irregularly shaped fiberglass sheet, thereby avoiding the phenomenon of excessively thick or thin local spraying and improving the spraying quality.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0027] Example

[0028] like Figures 1-6 As shown, in this embodiment, the fiberglass sheet surface spraying device includes a base 1, a sliding seat 2, and an adjustment mechanism 3. The sliding seat 2 is disposed above the base 1 and is used to restrict subsequent parts. The adjustment mechanism 3 includes a cleaning rod 305 disposed below the sliding seat 2. The brush at the bottom of the cleaning rod 305 is used to clean the surface of the irregularly shaped fiberglass sheet. Two sets of shock-absorbing casters 306 are installed at the bottom of the cleaning rod 305. The cooperation between the shock-absorbing casters 306 and the cleaning rod 305 assists the cleaning rod 305 in moving on the surface of the irregularly shaped fiberglass sheet being cleaned, preventing the brush from being damaged by gravity or other factors. Excessive force applied to the cleaning area can scratch the coating. An inner telescopic rod 303 is fixedly connected to the top of the cleaning rod 305. The bottom of the inner telescopic rod 303 is connected to a nozzle 304, which is rotatably connected to the top wall of the cleaning rod 305. A telescopic spring 302 is sleeved on the outer wall of the inner telescopic rod 303. The telescopic spring 302 extends to both ends in its natural state. The top of the telescopic spring 302 is fixedly connected to the bottom of the inner telescopic rod 303. An outer telescopic rod 301 is provided at both ends of the telescopic spring 302. The outer telescopic rod 301 is fixedly connected to the bottom of the sliding seat 2 to assist the movement of subsequent parts.

[0029] like Figures 1-6 As shown, in some embodiments, two sets of connecting plates 4 are fixedly connected to the top of the base 1 to support subsequent parts. Two sets of slotted support rods 8 are fixedly connected to the inner sidewall of the connecting plate 4. An electric trolley 7 is slidably connected inside the slotted support rod 8. One side of the electric trolley 7 is fixedly connected to both ends of the sliding seat 2, thereby maintaining the posture of the sliding seat 2. A servo motor 9 is installed on one side of the electric trolley 7. A threaded rod 5 is fixedly connected to the output end of the servo motor 9. The servo motor 9 drives the rotation of the threaded rod 5. The outer sidewall of the threaded rod 5 is connected to the sliding seat 2. The outer wall of the movable seat 2 is rotatably connected. The upper and lower sides of the sliding seat 2 are provided with moving grooves 12. The sliding ink bladder 6 moves inside the moving groove 12. The bottom end of the sliding ink bladder 6 is connected to the top end of the inner telescopic rod 303. The electric trolley 7 is started to drive the sliding seat 2 to move intermittently laterally inside the slotted support rod 8. At the same time, the servo motor 9 is started to drive the sliding ink bladder 6 to reciprocate inside the moving groove 12. Thus, the sliding ink bladder 6 drives the telescopic spring 302, the inner telescopic rod 303 and the nozzle 304 to move, in preparation for the subsequent spraying work.

[0030] like Figures 1-6As shown, in some embodiments, a sliding rotating block 10 is fixedly sleeved on the top of the cleaning rod 305. A contact ring is fixedly connected to the top of the sliding rotating block 10, and the top of the contact ring contacts the bottom of the outer telescopic rod 301. This allows the cleaning rod 305 to drive the sliding rotating block 10 and the outer telescopic rod 301 to move up and down synchronously when the cleaning rod 305 is raised and lowered. Several sets of teeth 13 are fixedly connected to one side of the outer telescopic rod 301. A gear 11 meshes with one side of the teeth 13, causing the gear 11 to rotate when it moves. The gear 11 is fixedly connected to the top of the cleaning rod 305 and rotatably connected to the outer side wall of the inner telescopic rod 303. A conveyor belt is installed on the surface of the base 1. Fixed blocks 601 are fixedly connected to both sides of the sliding ink sac 6. The fixed blocks 601 and the threaded rod 5 are threadedly connected to each other, thereby allowing the threaded rod 5 to move. The rotation of the ink sac 6 causes the sliding ink sac 6 to move inside the sliding seat 2. The top of the sliding ink sac 6 is equipped with a cover to prevent paint evaporation. The outside of the sliding ink sac 6 is made of rubber to give it a certain degree of elasticity. When the telescopic spring 302 moves, it drives the gear 11 to move, so that it can rotate with the teeth 13. The rotation of the gear 11 drives the brush at the bottom of the cleaning rod 305 to rotate, thereby cleaning the surface of the irregular fiberglass sheet and preventing dust from affecting the spraying effect. At the same time, the outer telescopic rod 301, the telescopic spring 302 and the inner telescopic rod 303 assist the cleaning rod 305 in adjusting its height to follow the surface of the irregular fiberglass sheet, so that the nozzle 304 is kept at a fixed distance from the surface of the irregular fiberglass sheet, thereby avoiding the phenomenon of excessive or insufficient local spraying and improving the spraying quality.

[0031] like Figures 1-6 As shown, in some embodiments, the outer wall of the sliding ink sac 6 is provided with an anti-clogging mechanism 14. The anti-clogging mechanism 14 includes an electromagnetic acceleration ring 1401, a sliding track 1402, and a ball bearing 1403. The sliding track 1402 is fixedly connected to the outer wall of the sliding ink sac 6. Several sets of electromagnetic acceleration rings 1401 are fixedly connected to the outer wall of the sliding track 1402. The ball bearing 1403 moves inside the sliding track 1402. One end of the ball bearing 1403 contacts the outer wall of the sliding ink sac 6. The electromagnetic acceleration ring 1401 generates a magnetic field when energized. Using the principle of electromagnetic acceleration, the ball bearing 1403 is driven to roll inside the sliding track 1402. The ball bearing 1403 continuously vibrates the sliding ink sac 6, causing the paint inside to be subjected to external force movement, thereby preventing clumping.

[0032] The method for spraying fiberglass sheet surfaces includes the following steps:

[0033] S1: Preparation steps: Fix the irregularly shaped fiberglass sheet inside the base 1, and adjust the sliding ink bladder 6 to the edge of the irregularly shaped fiberglass sheet via the electric trolley 7, in preparation for spraying the irregularly shaped fiberglass sheet.

[0034] S2: Moving steps: Start the electric trolley 7 to drive the sliding seat 2 to move intermittently laterally inside the slotted support rod 8, and at the same time start the servo motor 9 to drive the sliding ink bladder 6 to reciprocate inside the moving slot 12, thereby driving the telescopic spring 302, the inner telescopic rod 303 and the print head 304 to move through the sliding ink bladder 6.

[0035] S3: Cleaning and spraying steps. When the telescopic spring 302 moves, it drives the gear 11 to move, so that it rotates in conjunction with the teeth 13. The rotation of the gear 11 drives the brush at the bottom of the cleaning rod 305 to rotate, thereby cleaning the surface of the irregular fiberglass sheet and preventing dust from affecting the spraying effect. At the same time, the outer telescopic rod 301, the telescopic spring 302 and the inner telescopic rod 303 assist the cleaning rod 305 in adjusting its height to follow the surface of the irregular fiberglass sheet, so that the spray head 304 maintains a fixed distance from the surface of the irregular fiberglass sheet, thereby avoiding the phenomenon of excessively thick or thin local spraying and improving the spraying quality.

[0036] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
