Description

Technical Field

[0001] The invention relates to the technical field of plate pressing, and in particular to an automatic pressing machine for multi-layer plates. Background Art

[0002] Multi-layer board is a kind of man-made board composed of three or more layers of wood boards. It is usually made by gluing various woods together and subjecting them to high-pressure compression. It has strong bending resistance and shock resistance. Its surface can also be processed into various texture effects. Therefore, it is widely used in furniture manufacturing, architectural decoration and other industries.

[0003] At present, the production and processing of multi-layer boards are mostly completed by manual cooperation with machines. Workers are required to place the boards neatly, evenly apply glue on the bonding surface of the boards, and perform auxiliary pressing to achieve preliminary bonding between the boards. Subsequently, the pre-treated boards need to be manually transported to the conveying equipment, and the conveying equipment is used to transport the boards to the pressing equipment for final pressing. According to the specific needs of customers, decorative paper needs to be laid on the surface of the board before pressing, and then pressed and shaped together with the board. However, since the texture of decorative paper is relatively soft, when the board area is large, if you want to make the decorative paper be laid flat on the board, it often requires the cooperation of multiple workers to complete the laying, which is inefficient and will increase additional labor costs.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Embodiment 1: A multi-layer sheet automatic laminating machine, such as Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, it includes a frame 1, a conveying module 2, a placement table 3, a limiting frame 31, a guide column 32, a hydraulic unit 4, a pressing plate 41, a mounting folding frame 42 and a guide ring 43. The conveying module 2 is installed on the inner side of the top of the frame 1. A placement table 3 for placing a plate is arranged on the conveying surface of the conveying module 2. Five guide columns 32 are arranged at the bottom of the placement table 3. The limiting frame 31 is slidably connected to the placement table 3 through the five guide columns 32, and a spring is arranged between the limiting frame 31 and the guide column 32 located at the center position of the bottom of the placement table 3. Under the action of the spring, the limiting part of the limiting frame 31 can be higher than the placement plane of the placement table 3, and the limiting part is chamfered to assist in placing the plate. The hydraulic unit 4 is arranged The frame 1 is in the middle of the top and a pressing plate 41 is arranged on the hydraulic part 4. The pressing surface of the pressing plate 41 is larger than the placing surface of the placing table 3. When the conveying module 2 conveys the placing table 3 to the bottom of the hydraulic part 4, the hydraulic part 4 is used to drive the pressing plate 41 to descend, so as to cover the placing table 3 as a whole. The edge part thereof will first contact the limiting part of the limiting frame 31, and force the limiting frame 31 to descend along the guide column 32, and then the upper plate will be pressed. A mounting folding frame 42 is fixed by bolts to the right position on the upper surface of the pressing plate 41, and a guide ring 43 is fixedly installed at the front end of the mounting folding frame 42. The mounting folding frame 42 and the guide ring 43 will rise and fall synchronously with the pressing plate 41.

[0034] like Figure 1 , Figure 4 and Figure 5 As shown, it also includes a sliding sleeve 44 and a suction component 5, and the suction component 5 is composed of a reciprocating motor 51, a guide frame 52, a return sliding frame 53 and an air suction fan 54, wherein the reciprocating motor 51 is installed at the bottom right of the frame 1, and the guide frame 52 is installed at the top right of the frame 1, and the installation positions of the two are located on the same vertical line, and the output shaft of the reciprocating motor 51 passes through the frame 1 and is connected to the guide frame 52, and the reciprocating motor 51 can drive the guide frame 52 to rotate, and the return sliding frame 53 is slidably connected to the guide frame 52 through a spring, and the suction fan 54 is installed at the bottom of the return sliding frame 53. 4. The air suction fan 54 is set in a quadrangular pyramid shape, and a flat groove matched with the placement table 3 is provided at the bottom thereof, and a plurality of air suction ports are evenly opened in the groove, which can smoothly adsorb the decorative paper into the groove, and when it is moved onto the placement table 3, the decorative paper is laid on the surface of the plate on the placement table 3, and a sliding sleeve 44 is fixedly provided on the top of the circular sliding frame 53, and the sliding sleeve 44 is slidably connected with the guide ring 43. When the reciprocating motor 51 drives the guide frame 52 to rotate, the sliding sleeve 44 will slide on the guide ring 43 accordingly, and when the pressing plate 41 drives the guide ring 43 to descend, it can drive the sliding sleeve to descend together.

[0035] When pressing the plates, the worker only needs to stack the plates on the placement table 3 in sequence, and use the limit frame 31 to position the plates so that the plates are aligned flatly, and use the conveying module 2 to convey the placement table 3 backwards. At the same time, start the reciprocating motor 51 to rotate the guide frame 52 180° counterclockwise, and the suction fan 54 will also rotate synchronously, and the sliding sleeve 44 will also slide on the guide ring 43, and will not hinder the rotation of the suction fan 54. Then, the suction fan 54 is used to absorb the decorative paper and turn it back through the reciprocating motor 51. At this time, the conveying module 2 just conveys the placement table 3 to the bottom of the suction fan 54, and the hydraulic unit 4 is used to lower the pressing plate 41, and the installation folding frame 42 and the guide ring 43 will also drop accordingly. Under the pressure of the sliding sleeve 44, the circular sliding frame 53 drives the suction fan 54 to descend along the guide frame 52. The suction fan 54 will first press down the limit frame 31 and make its groove fit into the placement table 3. At this time, the suction fan 54 is turned off and the pressing plate 41 is raised, so that the decorative paper can remain on the surface of the board to complete the laying. Then, the placement table 3 is continued to be transported by the conveying module 2. When the placement table 3 reaches under the pressing plate 41, the pressing plate 41 is lowered by the drive of the hydraulic unit 4. The pressing plate 41 will first contact the limit frame 31 and force it to descend along the guide column 32, and then pressure will be applied to the board to complete the pressing between the decorative paper and the board. At the same time, the latter group of boards will also complete the laying of the decoration, thereby improving production efficiency.

The left end of the pull rope is connected to the bottom end of the supporting column 62, and the bottom end of the supporting column 62 is initially located at a height lower than the winding wheel 64, and the right end of the pull rope passes around the winding wheel 64 and is connected to the counterweight 65.

[0037] After the decorative paper is stacked on the flat panel 63 in advance, the suction fan 54 can directly absorb the decorative paper on the flat panel 63 when it rotates counterclockwise, and as the amount of decorative paper on the flat panel 63 decreases, the counterweight 65 will pull the pull rope downward, and the direction of the pulling force will be changed by the winding wheel 64, which will cause the supporting column 62 to lift the flat panel 63 upward along the mounting frame 61, so that the top layer of decorative paper is always at the same height, which is convenient for the suction fan 54 to absorb it.

[0038] like Figure 1 , Fig. 9 and Fig.10 As shown, a cutting portion 7 is provided at the rear of the top of the frame 1, and a cutting frame 71 is provided on the cutting portion 7. The blade of the cutting frame 71 forms a closed loop that is compatible with the placement plane of the placement table 3. After the plate is pressed, the placement table 3 is conveyed to the bottom of the cutting frame 71 by the conveying module 2. The cutting portion 7 is used to drive the cutting frame 71 to descend, so that the edges and corners of the plate can be cut off to keep the edges of the pressed plate flat.

[0039] like Figure 1 and Fig.11 As shown, a collecting box 8 is fixed by bolts on the frame 1 just below the cutting part 7, and a baffle 81 is slidably provided at the bottom of the collecting box 8. The scraps cut off by the cutting frame 71 will directly fall into the collecting box 8 for centralized collection. After the collecting box 8 is full, the baffle 81 can be pulled out to the right to allow the scraps to fall into the storage container placed at the bottom of the collecting box 8 in advance, and they will be processed uniformly after transfer.
