Description

Technical Field

[0001] The utility model relates to artificial board processing equipment, and more particularly to an artificial board surface repairing device. Background Art

[0002] Due to the defects of the board core itself, there will be some pits on the surface of the artificial board that has been formed. These pits not only affect the aesthetics of the board surface, but are also easily affected by collisions during transportation and expand or cause edge peeling, thus affecting the quality of the artificial board. The current treatment method for these pits is to repair them through artificial board surface repair equipment. Figure 1-2 As shown, a conventional artificial board surface repair device includes a bracket 8, a main body 2, a loading trough 3, a roller painting assembly, a scraper 4, and a discharge trough 5 disposed within the main body 2. A return pipe 7 and a feed pipe 6 are provided above the loading trough 3. The artificial board 1 is located within the roller painting assembly. The paint (typically a specialized putty powder slurry) in the loading trough 3 is transported to the roller painting assembly. The roller painting assembly then roller-paints both sides of the artificial board 1. The scraper 4 then smoothes the paint on the board surface, completing the surface repair process. The paint scraped off by the scraper 4 falls into the discharge trough 5, where it is pumped back to the loading trough 3 for recycling via the return pipe 7 and a pump. However, since both the upper and lower troughs are open-top structures, when the pump extracts the paint, it is necessary to wait until the paint in the lower trough 5 reaches a certain amount before it can be extracted. Therefore, during the paint circulation process, some water in the paint will evaporate, causing the paint to become thicker, which is not conducive to painting the artificial board and results in poor painting effect. Utility Model Content

DETAILED DESCRIPTION

[0023] The present invention will be further described below in conjunction with the embodiments, but this does not constitute any limitation to the present invention. Any limited modifications made by anyone within the scope of the claims of the present invention are still within the scope of the claims of the present invention.

[0024] See Figures 1-6 The present invention provides a surface repair device for artificial boards, comprising a bracket 8, a main body 2, a loading chute 3 disposed within the main body 2, a roller painting assembly, a scraper 4, and a discharge chute 5. A return pipe 7 and a feed pipe 6 are provided above the loading chute 3. These components are all found in existing surface repair devices for artificial boards, and the present invention does not improve upon them, so further discussion will not be provided.

[0025] The improvements of the present invention based on the original artificial board surface repair device are as follows:

[0026] The chute 5 is equipped with a spiral feed assembly for delivering the paint in the chute 5 below the scraper 4 to the center of the chute 5. A discharge port 18 is provided in the center of the bottom of the chute 5 to allow the paint to flow out of the chute 5. Because a spray pipe 9 is provided above the chute 5 in this embodiment, liquid replenisher can be sprayed through the spray pipe 9 to moisten the paint during the feeding process, avoiding the problem of paint scraped off by the scraper 4, resulting in a higher viscosity and poor circulation.

[0027] In this embodiment, the spiral feeding assembly includes a spiral feeding shaft 15, a spiral feeding shaft 2 16 and a bearing seat 17. The bearing seat 17 is fixedly mounted on the main body 2 above the feed chute 5 in a suspended manner, and the bearing seat 17 is located above the discharge port 18. One end of the spiral feeding shaft 15 and the spiral feeding shaft 2 16 are connected to the bearing seat 17, and the other ends of the spiral feeding shaft 15 and the spiral feeding shaft 2 16 are respectively rotatably connected to the main body 2, and one end of the spiral feeding shaft 15 and the spiral feeding shaft 2 16 that are rotatably connected to the main body 2 is connected to a motor 1, which is installed in the main body 2. The paint at both ends of the feed chute 5 is respectively delivered to the discharge port 18 located in the middle of the feed chute 5 by the two spiral feeding shafts, thereby achieving preliminary stirring of the paint, and the feeding amount is uniform, which is conducive to the wetting treatment of the paint.

[0028] Preferably, the feeding chute 5 is of V-shaped structure, and the bottom of the feeding chute 5 matches the outer diameter of the spiral feeding shaft, which is beneficial to the feeding of the spiral feeding shaft.

[0029] A storage box 11 is installed on the bracket 8, and the storage box 11 is connected to the discharge port 18 through a connecting pipe 10, and is used to receive the paint flowing out of the discharge port 18. Since these paints are added with liquid supplementary liquid, we need to further stir them to make them evenly mixed.

[0030] Specifically, a stirring paddle is rotatably installed in the storage box 11, a second motor 12 is fixedly installed on the bracket 8, and a driving end of the second motor 12 is fixedly connected to the stirring paddle, thereby achieving stirring of the paint in the storage box 11.

[0031] In order to achieve the recycling of paint, a connecting pipe 2 14 connected to the return pipe 7 is provided on one side of the storage box 11 of this embodiment, so that a circulation loop is formed between the storage box 11 and the loading trough 3. A control valve 2 is installed in the connecting pipe 2 14. In addition, a connector 13 connected to the interior of the storage box 11 is provided above the storage box 11, and the connector 13 is connected to the pipeline of the external boosting equipment. A control valve 1 is installed in the connecting pipe 10. That is, this embodiment changes the traditional method of extracting paint by pumping to compressing the paint in the storage box 11 into the loading trough 3 by compressed air, without the use of a pump, avoiding the problem of easy damage to the pump caused by extracting relatively viscous paint by pumping, and improving the reliability of the equipment.

[0032] In order to achieve the control of paint circulation, a proximity switch 19 is fixedly installed on the side wall of the storage box 11 of this embodiment, and a counterweight block 20 is slidably installed on the side wall of the storage box 11 below the proximity switch 19. A floating block 22 is provided in the storage box 11, and a bending rod 21 is fixedly installed on the counterweight block 20. The end of the bending rod 21 is inserted into the interior of the storage box 11 from the top of the storage box 11 and is fixedly connected to the floating block 22.

[0033] When the paint in the storage tank 11 is too low, the float 22 does not contact the paint in the storage tank 11. At this time, under the action of the counterweight 20, the counterweight 20 and the float 22 are at their lowest relative to the top of the storage tank 11. When the paint in the storage tank 11 increases and contacts the float 22, since the float 22 always floats on the paint, as the paint gradually increases, the float 22 and the counterweight 20 will rise simultaneously. When the counterweight 20 contacts the proximity switch 19, the proximity switch 19 is triggered and sends a signal to the controller, indicating that the paint in the storage tank 11 has reached the maximum liquid level. The controller then sends a control signal to the control circuit of the motor 2 12 to stop powering the motor 2 12. At the same time, the controller also sends a control signal to the control circuit of the external booster device and the control valve, causing the control valve 1 to close, the control valve 2 to open, and the external booster device to start, thereby supplying high-pressure gas to the storage tank 11 and pressurizing the paint into the return pipe 7. Among them, the reason for using a liquid level monitoring device composed of a float 22, a counterweight 20 and a proximity switch 19 is that the paint generally uses a special putty powder paint, which is not only relatively viscous but also has poor light transmittance. Therefore, it is necessary to use the linkage of the float 22 and the counterweight 20 to make the proximity switch 19 triggered externally, avoiding the problem that when the proximity switch 19 is installed inside the storage box 11, its probe is easily adhered to the paint and becomes ineffective.

[0034] Preferably, a positioning cylinder 23 is fixedly installed above the storage box 11, and a plug hole matching the diameter of the bending rod 21 is provided in the positioning cylinder 23, and the bending rod 21 is inserted into the plug hole. Such an arrangement can better position the bending rod 21 to prevent it from swinging left and right.

[0035] The working principle of the present utility model is as follows: when the surface repair device for artificial board is started, the feed pipe 6 feeds the paint into the feeding trough 3, the motor 1 and the motor 2 12 are both started, driving the spiral feed shaft to rotate, and the control valve 1 is in the open state, and the control valve 2 is in the closed state. When the device scrapes the paint on the surface of the artificial board 1 to level it, the paint scraped from the artificial board 1 will fall from the two ends of the scraper 4 to the two ends of the discharge trough 5, and the paint in the discharge trough 5 is transferred to the discharge port 18 through the spiral feed shaft and falls into the storage box 11. It should be noted that whether the spray tube 9 sprays the liquid replenisher needs to be determined according to the actual situation and is controlled by the on-site staff. The stirring paddle in the storage box 11 will stir these paints.

[0036] As the paint in the storage box 11 increases, when the float 22 and the counterweight 20 rise at the same time, and when the counterweight 20 contacts the proximity switch 19, the proximity switch 19 is triggered, indicating that the paint in the storage box 11 has reached the highest liquid level. At this time, after receiving the electrical signal from the proximity switch 19, the controller sends a control signal to the control circuit of motor 2 12 to stop powering motor 2 12. At the same time, the controller also sends a control signal to the control circuit of the external boosting device and the control valve, so that the control valve 1 is closed, the control valve 2 is opened, and the external boosting device is started, thereby sending high-pressure gas into the storage box 11 to pressurize the paint to the reflux pipe 7 and return it to the loading trough 3.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention. These modifications and improvements will not affect the effect of the implementation of the present invention and the practicality of the patent.
