Abstract
Description
Technical Field
[0001] This utility model relates to the field of spraying equipment technology, specifically to an automatic fiberglass spraying machine. Background Technology
[0002] During manufacturing, bathtubs are coated with fiberglass (also known as glass fiber). Fiberglass significantly enhances the bathtub's strength and durability, making it more robust and able to withstand greater pressure and weight, thus extending its lifespan. Due to fiberglass's low thermal conductivity, fiberglass-coated bathtubs have better heat retention, preventing users from feeling cold while bathing. The fiberglass coating also makes the bathtub surface smoother, reducing scratches and wear, and improving the overall aesthetics and user experience.
[0003] A search revealed a patent, CN217341907U, which discloses an automated outdoor bathtub fiber-coating machine. This machine includes a mounting frame with a turntable inside for placing the bathtub. The bottom of the turntable is rotatably connected to the mounting frame via a rotating shaft. An arc-shaped cover is positioned above the turntable, and an arc-shaped slide rail is fixed to the inner wall of the cover. A high-pressure nozzle is slidably connected to the arc-shaped slide rail. An arc-shaped notch corresponding to the slide rail is opened on the side wall of the cover, and a reciprocating screw is installed within the notch. Both ends of the reciprocating screw are rotatably connected to connecting rods via rotating sleeves. The connecting rods are fixed to the outer wall of the arc-shaped cover. A screw pair is slidably sleeved onto the reciprocating screw. A U-shaped frame is fixed to the side of the high-pressure nozzle facing the arc-shaped opening. This invention can automatically coat and reinforce the surface of the bathtub with fiber, improving work efficiency while ensuring uniform fiber coating.
[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:
[0005] In reality, outdoor bathtubs are large in size and come in various shapes, including round, rectangular, or irregular shapes. When the aforementioned patent requires spraying fiberglass onto large bathtubs of various shapes, there may be blind spots in the spraying process, which reduces the applicability of the spraying equipment to large bathtubs. Therefore, there is an urgent need in the field to improve the automatic fiberglass spraying machine to solve the defects of the existing technology. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figures 1-5 The automatic fiberglass spraying machine includes a support base 1, a rotating disk 2 on the upper part of the support base 1 for placing the workpiece 3 to be sprayed, vertical columns 4 on opposite sides of the support base 1, a top beam 5 fixedly connected between the upper ends of the two vertical columns 4, a first drive unit 6 on the side of the support base 1 for driving the vertical columns 4 to move, an upper spray nozzle 7 for spraying at the lower part of the top beam 5, side spray nozzles 8 on the opposite sides of the two vertical columns 4, a second drive unit 9 on the upper side of the vertical columns 4 for driving the upper spray nozzles 7 to move, a third drive unit 10 on the upper part of the vertical columns 4 for driving the side spray nozzles 8 to move, and a rotary drive component 32 at the lower part of the support base 1 for driving the rotating disk 2 to rotate.
[0029] Specifically, the aforementioned part 3 to be sprayed is a large outdoor bathtub. When glass fiber spraying is required on part 3, a lifting device is used to transfer part 3 to be placed on the upper part of the rotating disk 2. The rotation drive 32 can drive the rotating disk 2 to rotate, adjusting the direction of part 3 so that the two side spray nozzles 8 can spray the sides of part 3. The first drive unit 6 drives the vertical column 4 to move. When the top beam 5 and the vertical column 4 move to match the position of part 3, the upper spray nozzle 7 is turned on, and the second drive unit 9 drives the upper spray nozzle 7 to move horizontally, spraying the upper part of part 3. The spraying process begins by activating the side spray nozzle 8, which, in conjunction with the third drive unit 10, moves up and down to spray the opposite side or a single side of the part 3 to be sprayed. During spraying, the vertical column 4 continues to move, and then the rotating disk 2 rotates again, changing the direction of the part 3 to be sprayed, and spraying the opposite side of the part 3 to be sprayed again. With the above settings, bathtubs of different shapes and sizes can be sprayed, increasing the overall range of applications of the spraying device. Furthermore, the overall device's movement trajectory can be programmed by an external main controller according to the shape and size of the part 3 to be sprayed, thus automating the spraying of glass beads on bathtubs.

The first drive motors 11 are used to drive the first drive screw 14 to rotate. When the first drive motors 11 are started, the two first drive motors 11 are synchronous motors. The output end of the first drive motors 11 drives the first drive screw 14 to rotate. When the first drive screw 14 rotates, it drives the first sliding block 12 to move in the first sliding groove 13. The two first sliding blocks 12 drive the vertical column 4 to move, thereby realizing the movement of the vertical column 4 and the top beam 5.
