Description

Technical Field

[0001] This invention relates to the field of bathtub processing technology, specifically to an acrylic bathtub felting device. Background Technology

[0002] Acrylic bathtubs are made of PMMA plastic. The tub body consists of a surface layer (acrylic layer) and an inner layer (fiberglass resin reinforcement layer). They are characterized by a variety of shapes, light weight, a smooth surface, and low price. However, acrylic material has drawbacks such as poor high-temperature resistance, pressure resistance, and wear resistance, and its surface is prone to aging.

[0003] To improve the strength of the bottom of an acrylic bathtub, a surface felt (a type of glass fiber that is softer than regular glass fiber) is laid on the bottom. The laying process is as follows: first, a primer resin (vinyl resin) is sprayed on the bottom of the tub. After an interval of 8 to 10 minutes, a second primer is applied to ensure the adhesion between the subsequent resin and the bottom of the tub. Then, the surface felt is laid, and a second layer of resin is sprayed after laying to ensure the strength of the bottom.

[0004] However, when laying the surface felt at the bottom of an acrylic bathtub, since the work is done on the bottom of the bathtub, the workers need to manually flip the bathtub so that the bottom is facing up. At least two people are needed, standing on either side of the bathtub to do the work. Since the bathtub is heavy, flipping it is quite difficult and the labor intensity is high.

[0005] Therefore, the present invention designs an acrylic bathtub felting device to solve the problems existing in the prior art. Summary of the Invention

[0006] The purpose of this invention is to provide an acrylic bathtub felting device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an acrylic bathtub felt-laying device, comprising: a base, a bracket mounted on the top of the base, a material storage box located below the bracket, a spray head connected to the bottom of the material storage box, an adjustment component for adjusting the front-back, left-right position of the spray head on the bracket, inlet and outlet components on both sides of the top of the base, two vertical plates mounted on the top of the inlet and outlet components, vertical grooves formed on the sides of the two vertical plates that are close to each other, an electric cylinder mounted at the bottom of the vertical groove, a lifting plate connected to the output end of the electric cylinder, the lifting plate being slidably connected to the vertical groove, a motor slot formed on one side of the lifting plate, a flipping motor mounted in the motor slot, a mounting plate connected to the output end of the flipping motor, an electric push rod mounted on the mounting plate, and a frame plate connected to the output end of the electric push rod. A positive and negative threaded rod is rotatably installed between the bottom two sides of the frame plate. A transverse sliding plate is slidably installed on the outer side walls of both sides of the positive and negative threaded rod via threads. An installation groove is opened below the transverse sliding plate, and a switching motor is installed in the installation groove. The output end of the switching motor is connected to a clamping block. The side of the two clamping blocks that are far apart from each other is a flat surface, and the side of the two clamping blocks that are far apart from each other is an arc-shaped concave surface and an arc-shaped convex surface, respectively. Because the base coat of resin is thick, it takes 8 to 10 minutes before the second base coat can be applied. The adjusting component can move the spray head to the top of another bathtub to apply the first base coat to the other bathtub. After spraying, it returns to the first bathtub to apply the second base coat, and then applies the second base coat to the second bathtub. In this way, the spray head can continue spraying during the waiting time, improving the spraying efficiency.

[0008] Preferably, the adjusting assembly includes a long lead screw, which is rotatably mounted between the top two sides of the bracket. A sliding plate is slidably mounted on the outer side wall of the long lead screw via threads. A through groove is provided below the sliding plate, and an electric telescopic rod is installed in the through groove. An adjusting frame is connected to the output end of the electric telescopic rod. A short lead screw is rotatably mounted between the bottom two ends of the adjusting frame. An mounting block is slidably mounted on the outer side wall of the short lead screw via threads. The mounting block and the adjusting frame are slidably connected. The bottom of the mounting block and the top of the storage box are fixedly mounted.

[0009] Preferably, a crossbar is installed between the top two sides of the bracket, and the crossbar is slidably connected to the slide plate, which can guide the slide plate.

[0010] Preferably, the inlet / outlet assembly includes two long frames mounted on top of the base. A screw is rotatably mounted between the two ends of the long frames. One end of the screw is connected to the output end of the inlet / outlet motor. A screw block is slidably mounted on the outer wall of the screw via a thread. The screw block is slidably connected to the long frame. The tops of the two screw blocks are respectively fixedly mounted to the tops of two vertical plates. Rotating the screw can adjust the position of the screw blocks, allowing the vertical plates to move and facilitating the movement of the clamping block to the top of the trolley, thereby facilitating the loading and unloading of the bathtub.

[0011] Preferably, the flat, concave, and convex surfaces are all provided with rubber pads, which can improve the clamping effect on the side wall of the bathtub.

[0012] Preferably, a vertical rod is installed between the upper and lower ends of the vertical groove, and the vertical rod is slidably connected to the lifting plate, with the vertical rod serving to limit the movement of the lifting plate.

[0013] Preferably, each end of the base is equipped with two trolleys, which facilitate the transportation of the bathtub.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. This invention uses two electric push rods to move two frame plates to the top sides of the bathtub, then an electric cylinder drives the frame plates to descend. Subsequently, the forward and reverse threaded rods rotate, causing two clamping blocks to move closer together. The two clamping blocks on both sides can then clamp the sides of the bathtub. Then, the electric cylinder drives the bathtub to rise, and the flipping motor rotates 180 degrees to flip the bathtub over. No manual flipping is required, reducing the workload of the staff. Furthermore, by switching the motor to change the position of the clamping blocks, the two flat surfaces can clamp rectangular bathtubs, while the arc-shaped concave and arc-shaped convex surfaces can improve the clamping effect when clamping elliptical bathtubs.

[0026] Please see Figure 1-3 In this embodiment: a crossbar 508 is installed between the top two sides of the bracket 2, and the crossbar 508 and the slide plate 502 are slidably connected.

[0027] Please see Figure 1-3 In this embodiment: the inlet / outlet assembly 6 includes two long frames 601, which are mounted on the top of the base 1. A screw 602 is rotatably mounted between the two ends of the long frame 601. One end of the screw 602 is connected to the output end of the inlet / outlet motor 603. A screw block 604 is slidably mounted on the outer wall of the screw 602 through a thread. The screw block 604 and the long frame 601 are slidably connected. The tops of the two screw blocks 604 are respectively fixedly mounted to the tops of the two vertical plates 7.

[0028] Please see Figure 1-3 In this embodiment: rubber pads 24 are provided on the surfaces of the plane 21, the concave arc surface 22 and the convex arc surface 23.

[0029] Please see Figure 1-3 In this embodiment: a vertical rod 25 is installed between the upper and lower ends of the vertical groove 8, and the vertical rod 25 and the lifting plate 10 are slidably connected.

[0030] Please see Figure 1-3 In this embodiment: both ends of the base 1 are equipped with two trolleys 26.

[0031] Working principle: After the trolley 26 delivers the acrylic bathtub to be covered with felt to one end of the base 1, the screw 602 drives the screw block 604 to move, causing the vertical plate 7 to move to the side of the bathtub. Then, the electric push rod 14 extends, causing the two frame plates 15 to move above the two side edges of the bathtub respectively. Then, the electric cylinder 9 drives the lifting plate 10 to descend, causing the clamping block 20 to descend. Then, the positive and negative threaded rods 16 rotate, which brings the two clamping blocks 20 closer together. For square bathtubs, the flat surface 21 can be used for clamping. For oval bathtubs, the switching motor 19 can be activated to move the clamping blocks 20 closer together. Rotate 180 degrees, then use the concave surface 22 and convex surface 23 to clamp the two side walls of the bathtub. After clamping, the electric cylinder 9 drives the bathtub to rise away from the trolley 26. Then, the flipping motor 12 drives the mounting plate 13 to rotate 180 degrees, flipping the bathtub so that the bottom of the bathtub faces upwards. After the bathtub is flipped, no personnel are needed to flip it, making it convenient to lay the felt. After both bathtubs are flipped, the screw block 604 drives the vertical plate 7 to move below the storage box 3. Then, the electric telescopic rod 504 drives the spray head 4 to descend close to the bottom of the bathtub. Then, the spray head 4 first sprays a tree on one bathtub. The resin is applied for the first coat. The long lead screw 501 moves the sliding plate 502, causing the material storage tank 3 to move the spray head 4 left and right. Simultaneously, the short lead screw 506 moves the mounting block 507 back and forth, causing the spray head 4 to move back and forth as well. This allows resin to be sprayed onto different areas of the bathtub bottom. After spraying, since it takes 8-10 minutes before the second coat of priming can be applied, the sliding plate 502 can move the spray head 4 to the top of another bathtub to apply the first coat of priming to that bathtub. After spraying, the spray head 4 returns to the first bathtub to apply the second coat of priming. Then, a second coat of primer is applied to the second bathtub. This allows the spray nozzle 4 to continue spraying while waiting, improving spraying efficiency. After the primers on both sides are applied, the worker lays a surface felt on the bottom of the bathtub. After laying it, another coat of resin is applied to complete the felting process. Once completed, the vertical plate 7 is moved to the trolley 26 at the other end of the base 1, and the worker lifts the bathtub onto the trolley 26 and transports it away. Any content not described in detail in this instruction is prior art known to those skilled in the art.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
