Description

Technical Field

[0001] The invention belongs to the technical field of furniture coating equipment, in particular to a coating device for panels during furniture processing. Background Art

[0002] Furniture refers to a large category of equipment and facilities that are essential for humans to maintain normal life, engage in production practice and carry out social activities. Furniture has also been continuously developing and innovating with the times. Today, there are many categories, different materials, complete varieties and different uses. With the improvement of people's living standards, the requirements for the aesthetics of furniture are gradually increasing. Nowadays, the surface of furniture materials is often coated during the production and processing process.

[0003] When laminating plate materials for furniture making, the plates are generally placed horizontally and then the operators perform the laminating operation. The manual operation is no longer applicable to modern production operations and has low work efficiency. Summary of the invention

[0004] In order to solve the above problems, the purpose of the present invention is to provide a coating device for panels during furniture processing.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: a coating device for panels during furniture processing, comprising a placing platform and a coating platform located above the placing platform, and driving members are arranged on both sides between the placing platform and the coating platform, and the driving members are used to drive the coating platform to move vertically;

[0006] A placement slot is provided on the placement platform, and the placement slot is connected to a negative pressure group;

[0007] A winding roller is arranged on one side of the film-coating platform, and a preheating component for preheating the film is arranged on the winding roller. A conveying component is arranged on the other side of the film-coating platform, and a cleaning component is installed on the conveying component.

[0008] The following beneficial effects are achieved by adopting the above scheme: (1) In the present invention, the film on the roll is adsorbed by the transport component, and then the film is transported by the conveying component. When the film passes through the preheating component, the preheating component heats the film to a certain extent, so that the film can be covered on the plate. At the same time, in the process of transporting the film, the impurities on the plate are cleaned by the cleaning component, and the film coating platform is driven by the driving component to move toward the plate on the placement platform until the film is attached to the plate, and then the air between the film and the plate is extracted by the negative pressure group to achieve the purpose of coating. In this way, compared with the manual coating of the prior art, its efficiency is significantly improved.

[0009] (2) In the present invention, the film is softened to a certain extent by preheating the assembly, and then the negative pressure of the negative pressure group is used to make the film further adhere to the plate, which reduces the probability of bubbles between the film and the plate compared to the manual attachment in the prior art. Of course, the softened film will collapse to a certain extent, which can press out the gas between the film and the plate, and cooperate with the negative pressure group to improve the laminating effect.

[0010] Furthermore, the negative pressure group includes a first negative pressure hole group and a second negative pressure hole group arranged on the placement platform, the first negative pressure hole group and the second negative pressure hole group are both connected to a first negative pressure pump, the first negative pressure hole group includes a plurality of first negative pressure holes arranged in an array, and the second negative pressure hole group includes a plurality of second negative pressure holes arranged along the periphery of the first negative pressure hole group.

[0011] Beneficial effect: In the present invention, the negative pressure between the film and the plate is removed through the second negative pressure hole, so that the film and the plate are closely attached. Since the second negative pressure hole is arranged along the periphery of the first negative pressure hole, the plate can be subjected to negative pressure all around, that is, the negative pressure treatment is simultaneously applied to the surroundings and the surface of the plate. The first negative pressure hole is used to adsorb the plate to stabilize the plate and facilitate the lamination work.

[0012] Further, the diameter of the first negative pressure hole is greater than the diameter of the second negative pressure hole.

[0013] Beneficial effect: The diameter of the first negative pressure hole is greater than that of the second negative pressure hole, and different pressures are applied to the plate and the film.

[0014] Furthermore, the winding roller includes a support plate installed on the coating platform, a roller shaft is rotatably connected to the support plate, at least two support plates are fixedly connected to the support plate, and a leveling roller is rotatably connected to the support plate.

[0015] Beneficial effect: In the present invention, the film is leveled by the leveling roller, thereby reducing the probability of the film being uneven.

[0016] Furthermore, a preheating assembly is arranged on the support plate, and the preheating assembly includes a heat conducting plate, a heating plate is arranged on one side of the heat conducting plate, an electric control cylinder is arranged above the heating plate, and an output shaft of the electric control cylinder is fixedly connected to the heating plate.

[0017] Beneficial effect: In the present invention, the film is cut by the heating plate, and the heating plate is driven to slide vertically by the electric control cylinder to facilitate the cutting of the film, and the residual heat of the heating plate is transferred to the support plate and the leveling roller through the heat conduction plate, so that the film is preheated.

[0018] Furthermore, the conveying assembly includes a motor fixedly mounted on the coating platform, the output shaft of the motor is coaxially fixedly connected with a lead screw, a mounting portion is fixedly connected to the nut seat of the lead screw, a finger cylinder is fixedly connected to the mounting portion, an adsorption disk is arranged between the fingers of the finger cylinder, the adsorption disk is connected to a second negative pressure pump, and the second negative pressure pump is mounted on the mounting portion.

[0019] Beneficial effects: In the present invention, the second negative pressure pump and the adsorption disk are used to pull the film between the fingers of the finger cylinder, and then the film is clamped by the finger cylinder, so that the finger cylinder drives the film to move. In the present invention, since the flattening roller can support the film at the cut-off position (away from the side of the finger cylinder), it is always convenient for the finger cylinder to clamp.

[0020] Furthermore, the cleaning assembly includes a plurality of cleaning brushes, which are mounted on the mounting portion, and the cleaning brushes are vertically slidably matched with the mounting portion.

[0021] Beneficial effect: In the present invention, the surface of the plate is cleaned by a cleaning brush, and the cleaning brush can slide vertically on the mounting portion, so it can adapt to plates of different thicknesses. Of course, if the plate has an uneven pattern, this cleaning method can also adapt.

[0022] Furthermore, a groove for placing the roller is provided on one side of the placement platform, and a through groove is provided on the other side of the placement platform.

[0023] Beneficial effect: The groove is used to place the roll, and the through groove is convenient for the cleaning brush to pass through, so as to avoid obstruction to the downward movement of the laminating platform.

[0024] Furthermore, the air outlet of the first negative pressure pump faces downward of the through groove.

[0025] Beneficial effect: The cleaning brush is cleaned by the first negative pressure pump, thereby reducing the probability of impurities remaining on the cleaning brush. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The present application embodiment provides a coating device for a panel 21 during furniture processing, which is basically as shown in the attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 and attached Figure 4 As shown, it includes a placing platform 11 and a coating platform 14 located above the placing platform 11, and driving components are arranged on both sides between the coating platform 14 and the placing platform 11. The driving component is a hydraulic cylinder 12, and the cylinder body of the hydraulic cylinder 12 is fixedly connected to the placing platform 11, and the output shaft of the hydraulic cylinder 12 is fixedly installed on the coating platform 14, and the hydraulic cylinder 12 drives the coating platform 14 to move vertically.

[0033] A winding roller is provided on one side of the film coating platform 14, and the winding roller includes a support plate 22 mounted on the film coating platform 14, and a roller shaft 23 is rotatably connected to the support plate 22, and the roller shaft 23 is arranged along the width direction of the film coating platform 14, and a preheating assembly is connected to the support plate 22, and the preheating assembly includes at least two support plates 33 fixedly mounted on the support plate 22, and a leveling roller 34 is rotatably connected to the support plate 33, and the leveling roller 34 is arranged along the length direction of the film coating platform 14, and a heat conducting plate 31 is fixedly connected to the support plate 33, and a heating plate 32 is vertically slidably matched on the side of the heat conducting plate 31 away from the support plate 22, and an electric control cylinder 152 is provided above the heating plate 32, and the output shaft of the electric control cylinder 152 is fixedly connected to the heating plate 32 to drive the heating plate 32 to slide vertically. In this embodiment, a conveying assembly is also provided on the other side of the film coating platform 14, and there are several conveying assemblies, which are arranged along the width direction of the film coating platform 14. The conveying assembly includes a motor fixedly mounted on the coating platform 14 , the output shaft of the motor is coaxially fixedly connected with a lead screw 15 , and a mounting portion 25 is fixedly connected to a nut seat 151 of the lead screw 15 .

[0034] A finger cylinder 26 is fixedly connected to the mounting portion 25 , a second negative pressure pump 28 is fixedly mounted above the finger cylinder 26 , a suction plate 27 is provided between fingers 29 of the finger cylinder 26 , and the suction plate 27 is connected to the second negative pressure pump 28 through a pipeline.

[0035] A cleaning assembly is installed below the mounting portion 25 , and the cleaning assembly includes a plurality of cleaning brushes 24 that vertically slide with the mounting portion 25 .

[0036] In this embodiment, as shown in the attached Figure 3 As shown, the second negative pressure pump 28 is started to generate negative pressure on the adsorption plate 27 (suction cup), and the film between the leveling rollers 34 is pulled by the negative pressure, and then the film is clamped by the finger cylinder 26, and then the motor drives the lead screw 15 to move, and the film passing through the leveling rollers 34 is leveled to reduce the unevenness. Of course, the cleaning component will also pass through the plate at this time. Since the cleaning brush 24 and the mounting part 25 are vertically slidably matched, it can adapt to plates 21 of different thicknesses. If there are uneven patterns on the plate 21, the pattern can also be cleaned.

[0037] When the length of the film is sufficient, the hydraulic cylinder 12 drives the film-coating platform 14 to move toward the plate 21 on the placement platform 11 until the film is attached to the plate 21. Then the electric control cylinder 152 is started, and the electric control cylinder 152 drives the heating plate 32 to move toward the cutting position of the film, and then cuts the film.

[0038] In this embodiment, the film is cut by the heating plate 32, and the cutting position is located on the side of the leveling roller 34 away from the support plate 22. Then, the film on the roller 23 will have excess on the leveling roller 34, which is convenient for the subsequent traction of the adsorption plate 27 and the clamping of the finger cylinder 26, so that the device can perform continuous coating work.

[0039] In this embodiment, initially, the heating plate 32 is always started, and the support plate 33 and the leveling roller 34 are heated by the heat conducting plate 31 , so that the film passing through the leveling roller 34 is preheated to a certain extent, so that the film becomes softer.

[0040] As attached Figure 1 and attached Figure 4 As shown, in this embodiment, a bracket 17 is installed at the bottom of the placement platform 11, and a placement groove is opened on the top surface of the placement platform 11, and the placement groove is connected to a negative pressure group, the negative pressure group includes a first negative pressure hole group 41 and a second negative pressure hole group 43, the first negative pressure hole group 41 includes a plurality of first negative pressure holes 41 arranged in an array, the second negative pressure hole group 43 includes a plurality of second negative pressure holes 43 arranged circumferentially along the first negative pressure hole group 41, the diameter of the first negative pressure hole 41 is larger than the diameter of the second negative pressure hole 43, the first negative pressure hole group 41 and the second negative pressure hole group 43 are both connected to a first negative pressure pump 18, and the first negative pressure pump 18 is fixedly mounted on the bracket 17.

[0041] In this embodiment, when the plate 21 is placed on the placement platform 11 , an annular groove is formed between the placement platform 11 and the plate 21 , and the second negative pressure hole 43 is located in the annular groove.

[0042] In this embodiment, a groove 16 is formed on the placement platform 11 below the roller, a through groove 19 is formed on a side of the placement platform 11 away from the groove 16 , and an air outlet of the first negative pressure pump 18 faces below the through groove 19 .

[0043] In this embodiment, the plate 21 is placed in the placement groove in advance, and then the first negative pressure pump 18 is used to suck negative pressure to the first negative pressure hole 41 and the second negative pressure hole 43. Under the action of negative pressure, the first negative pressure hole 41 firmly adsorbs the plate on the placement platform 11. When the film is attached to the plate, the air between the film and the plate 21 is sucked away, so that the plate 21 is tightly attached to the film.

[0044] In this embodiment, since the film has been preheated, it can be softened to a certain extent and collapse to a certain extent, which is conducive to pressing away the air between the film and the plate 21 and improving the coating effect.

[0045] In this embodiment, since the second negative pressure hole 43 is circumferentially located in the first negative pressure hole 41, the circumferential direction of the plate 21 can be subjected to negative pressure, and the film at the edge of the plate 21 will move toward the side of the plate, so that the side of the plate 21 can also be coated. Of course, since the diameters of the first negative pressure hole 41 and the second negative pressure hole 43 are different, different negative pressures are used to adsorb the plate and the film, which has higher adaptability.

[0046] In this embodiment, when the film is in contact with the plate 21, the roller extends into the groove 16 and the cleaning brush 24 extends into the through groove 19. This can avoid hindering the downward movement of the coating platform 14. When the cleaning brush 24 extends into the through groove 19 and passes through the through groove 19, the gas discharged by the first negative pressure pump 18 can clean the dust on the cleaning brush 24, reduce the residual dust on the cleaning brush 24, and utilize it for subsequent cleaning of the plate.

The ordinary technicians in the relevant field know all the common technical knowledge in the technical field of the invention before the application date or priority date, can obtain all the existing technologies in the field, and have the ability to apply the conventional experimental means before that date.
