In addition, "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means more than two.

[0044] See also Figure 2 The present invention provides a support component 3, comprising a bottom plate 31, a support frame 32, a support cylinder 33, a vertical lifting rod 34 and a support plate 35. The bottom plate 31 can be placed on a conveying frame 321 such as a spray line frame 321. The support frame 32 is arranged on the bottom plate 31, and is used to support the two wide sides of the bathtub inverted on the support component 3; the support cylinder 33 is vertically arranged on the bottom plate 31; the vertical lifting rod 34 is movably connected to the support cylinder 33 and can move upward and downward relative to the support cylinder 33, and a scale mark is provided on the vertical lifting rod 34; the support plate 35 is arranged at the upper end of the lifting rod, and the support plate 35 is used to abut against the inner bottom of the bathtub, so that when the bathtub is inverted on the support component 3, there is a large friction between the inner bottom of the bathtub and the support plate 35 and it will not move, thereby ensuring that the bathtub can be stably inverted on the support component 3, facilitating the spraying operation on the back of the bathtub.

[0045] When the size of the bathtub to be painted changes, the two wide sides of the bathtub are always supported by the support frame 32. Therefore, the support plate 35 can be ensured to abut the inner bottom of the bathtub by simply adjusting the support plate 35 to the appropriate height by moving the vertical lifting rod 34. In addition, because the vertical lifting rod 34 is provided with a scale mark, when the size of the bathtub to be painted changes, the production staff can quickly adjust the support plate 35 to the appropriate height based on the bathtub size and the scale mark, so that the bathtub will not move when it is inverted on the support assembly 3. Compared with the existing support assembly 3, the present invention only requires adjusting the height of the support plate 35 used to support the inner bottom of the bathtub before the bathtub is inverted on the support assembly 3. The production staff does not need to extend their head into the bathtub to adjust the support assembly 3 to a position where the bathtub can be placed. Therefore, the support assembly 3 provided by the present invention is more convenient to operate during use.

[0046] like Figure 2 As shown, the support frame 32 further includes a frame body 321, guide rails 322, and support rods 323. The frame body 321 is mounted on the base plate 31. Two guide rails 322 are provided, and the two guide rails 322 are arranged parallel to the frame body 321. Two support rods 323 are provided and perpendicular to the guide rails 322. Both guide rails 322 are arranged horizontally and movably on the two guide rails 322 and are used to support the two wide sides of the bathtub.

[0047] By movably setting the support rods 323 on the guide rails 322, the two support rods 323 can be moved to a suitable position without being too wide. When the bathtub is inverted on the support assembly 3, it is ensured that the two wide sides of the bathtub are in contact with the two support rods 323 at the same time.

[0048] like Figure 2 As shown, at least two support tubes 33 are provided, and both support tubes 33 are located within the rectangular space formed by the guide rails 322 and the support rods 323. The number of vertical lifting rods 34 is the same as the number of support tubes 33, and the bottom of the support plate 35 is simultaneously connected to the upper ends of multiple vertical lifting rods 34. By simultaneously connecting the support plate 35 to multiple vertical lifting rods 34, the present invention improves the load-bearing capacity of the support plate 35 and the vertical lifting rods 34. When the inner bottom of the bathtub abuts the support plate 35, the vertical lifting rods 34 are less likely to be damaged.

[0049] like Figure 2 and Figure 3 As shown, further, the support tube 33 is provided with a locking rod 36 that can abut against the outer wall of the vertical lifting rod 34, so that after the support plate 35 is adjusted to a suitable height, the vertical lifting rod 34 can be locked and will not move up and down. The locking rod 36 can be a T-shaped threaded rod to facilitate rotation by production personnel.

[0050] like Figure 4 As shown, a cushion 37 is further provided on the support plate 35. The cushion 37 may be a foam cushion. When the bathtub is inverted on the support assembly 3, the inner bottom of the bathtub directly contacts the cushion 37, which not only prevents structural damage to the inner bottom of the bathtub but also increases friction, making the bathtub less likely to move.

[0051] like Figure 1 、 Figure 4 and Figure 5 As shown, the present invention also provides a bathtub spraying production line, comprising a spray booth 1, a spray conveyor line 2 running through the spray booth 1, a support assembly 3, and a rotating member 4 located within the spray booth 1. The support assembly 3 carrying the bathtub can be transported into the spray booth 1 via the spray conveyor line 2, so that the back of the bathtub is sprayed with fiberglass resin within the spray booth 1.

[0052] Furthermore, the rotating member 4 is of prior art and is used to raise and lower the support assembly 3 and rotate the support assembly 3. A positioning rod 5 is also vertically provided on the rotating member 4. The support assembly 3 also includes a positioning cylinder 38. The positioning cylinder 38 is vertically provided at the bottom of the base plate 31 and is provided with a positioning hole that cooperates with the positioning rod 5.

[0053] When the object-carrying assembly 3 is transported to the top of the rotating member 4 through the spray conveyor line 2, the positioning rod 5 corresponds to the positioning cylinder 38 at the bottom of the base plate 31. After the rotating member 4 pushes up the object-carrying assembly 3 carrying the bathtub, the positioning rod 5 can be inserted into the positioning cylinder 38, so that the object-carrying assembly 3 and the rotating member 4 are connected together. In this way, when the rotating member 4 drives the object-carrying assembly 3 to rotate, the relative position relationship between the object-carrying assembly 3 and the rotating member 4 will not change. Therefore, after the spraying is completed, the object-carrying assembly 3 can be returned to the correct position on the spray conveyor line 2, ensuring that the bathtub can be transported out of the spray room 1 through the spray conveyor line 2 after the spraying is completed.

[0054] like Figure 5 and Figure 6 As shown, further, the spray conveyor line 2 includes two pairs of conveyor chains 21 arranged in parallel; the bathtub spraying production line also includes a dust cover 6; the dust cover 6 is in an inverted L shape, and the dust cover 6 is arranged above the conveyor chain 21 located in the spray room 1 to prevent a large amount of glass fiber resin from falling on the conveyor chain 21, ensuring that the spray conveyor line 2 can perform normal conveying operations.

[0055] like Figure 5 and Figure 6As shown, further, the upper portion of the two dust covers 6 is provided with a notch 61 for the bottom plate 31 to pass up and down, and the notch 61 is located next to the rotating member 4. By reserving the notch 61 on the upper portion of the dust cover 6, it can be ensured that the lifting and lowering of the object supporting assembly 3 located on the rotating member 4 will not be blocked by the dust cover 6.

[0056] like Figure 5 As shown, the bathtub spraying production line further includes an exhaust pipe 7. The exhaust pipe 7 is installed within the spray booth 1 and above the spray conveyor line 2. Multiple air inlets 8 are provided on the exhaust pipe 7. The exhaust pipe 7 is connected to a dust extraction fan. Powered by the dust extraction fan, dust containing fiberglass resin generated by spraying the bathtub is extracted through the exhaust pipe 7 and transported to a gas-solid separation device, such as a cyclone separator, for processing, thereby improving the working environment of the spray booth 1.

[0057] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and utility model concept of the present invention, and all these changes or substitutions should fall within the scope of protection of the claims attached to the present invention.
