Description

Technical Field

[0001] The present invention specifically relates to the technical field of artificial board fiber paving, and in particular to a fiber surface paving device for artificial board production. Background Art

[0002] Artificial board is a board made of wood or other non-wood plant fibers through a certain process. Artificial board is a three-layer or multi-layer board material made by peeling wood segments into veneers or planing wood blocks into veneers, and then gluing them with adhesives. Usually, the fiber directions of adjacent layers of veneers are perpendicular to each other. This structure makes plywood have higher strength and stability.

[0003] At present, when traditional artificial boards are produced, the fibers on the fiber surface need to be evenly laid. However, during the laying process of the fiber surface, the fibers may clump or pile up, which cannot effectively ensure the uniformity of the fibers of the artificial boards. In the later processing, the clumped or piled fibers may cause local expansion, which will affect the processing quality of the artificial boards. In addition, when laying the fibers, the weight of the artificial boards may be different, which may cause local bulges or depressions in the artificial boards during molding, and the quality of the artificial boards cannot be effectively guaranteed.

[0004] When the existing paving device is paving the fiberboard, the fibers are first weighed and then placed in the silo to achieve paving of the fibers. Although this can achieve consistency in the overall weight of the artificial board, during the paving process, the uneven paving may cause inconsistent weights at some parts or both ends of the artificial board, making it impossible to effectively guarantee the processing quality of the artificial board. It may also cause uneven heating of the artificial board during hot pressing, affecting the overall quality of the artificial board. Summary of the invention

[0005] The object of the present invention is to provide a fiber surface paving device for the production of artificial boards. In this device, a slider is arranged on the inner wall of the transmission frame, and a roller is arranged on one side of the slider through an extension block, and the roller contacts the bottom of the forming conveyor belt. In this way, when paving is carried out, when the weight of the slab on the forming conveyor belt causes the slider to slide downward along the slide rod, the slider drives the adjustment plate to move downward through the L-shaped connecting rod, so as to adjust the gap between the inner wall of the silo and the end of the adjustment plate, thereby effectively adjusting the unloading speed of the bottom of the silo, thereby effectively ensuring that the quality of the slabs on the forming conveyor belt is always within a controllable range, thereby ensuring subsequent processing and ensuring the production quality of the artificial boards, so as to solve the problems of the above-mentioned background technology.

[0008] The inner side wall of the transmission frame is provided with a plurality of rectangular grooves, and the side walls of the plurality of rectangular grooves are provided with protrusions; the protrusions are slidably connected with the slider; the slider is provided with a round hole for the sliding rod to pass through; a spring is provided at the bottom of the sliding rod; an extension block is fixedly installed on the side of the slider away from the protrusion; a roller is installed on the extension block through a seat bearing; the roller is in contact with the bottom surface of the forming conveyor belt; the two ends of the forming conveyor belt are cooperatively connected with the rotating rollers equipped with the first sprocket; the roller is in contact with the forming conveyor belt through the roller, so that when the weight of the slab on the forming conveyor belt changes, the slider drives the L-shaped connecting rod to adjust the speed of fiber unloading in the silo;

[0009] As a further technical solution of the present invention, a paving assembly is arranged on the top of the transmission frame; the paving assembly includes a frame body; the frame body is arranged at an angle; a plurality of first rollers and a second roller are arranged at intervals inside the frame body; wherein; the rotating shafts of the plurality of first rollers extend to the left side of the frame body; a third sprocket is installed on the rotating shafts of the plurality of first rollers; the plurality of third sprockets are connected by a third chain; wherein any rotating shaft of the plurality of first rollers is fixedly installed with a second driving motor; the first roller is driven to rotate by the second driving motor to realize effective transmission of the fiber through the roller, and during the transmission process, a slab is formed on the forming conveyor belt that falls through the gap between two adjacent rollers;

[0010] As a further technical solution of the present invention, the rotating shafts of the plurality of second rollers extend to the right side of the frame; the rotating shafts are all equipped with second sprockets; the plurality of second sprockets are connected by second chains; any rotating shaft of the plurality of second rollers is fixedly installed with a third drive motor; the third drive motor is arranged diagonally to the second drive motor; the second roller is driven to rotate by the second drive motor, so that the rotation direction between two adjacent rollers can be adjusted during the transmission process, thereby meeting different paving needs;

[0011] As a further technical solution of the present invention, a material unloading component is fixedly installed on the inner side of one end of the frame; the material unloading component includes a silo; the silo is arranged in a right-angle trapezoidal shape; wherein two symmetrical first slide rails are arranged on the inner side of the inclined surface of the silo; first C-shaped blocks are slidably installed on the first slide rails; the first C-shaped blocks are fixedly installed with the adjustment plate; when the adjustment plate moves downward, it moves obliquely downward along the first slide rail to adjust the distance between the end of the adjustment plate away from the first C-shaped block and the inner wall of the silo; thereby adjusting the unloading speed of the fiber;

[0012] As a further technical solution of the present invention, a second slide rail is provided at the bottom of the adjustment plate; a second C-shaped block is slidably mounted on the second slide rail; a mounting seat is mounted on the second C-shaped block; the mounting seat is movably mounted on the L-shaped connecting rod; one end of the L-shaped connecting rod away from the mounting seat penetrates the side wall of the silo and is fixedly mounted on the slider; when the L-shaped connecting rod pulls the mounting seat, the adjustment plate moves downward, and the second C-shaped block moves backward along the second slide rail;

[0013] As a further technical solution of the present invention, the bottom of the frame is fixedly mounted to the transmission frame through a plurality of support rods;

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In the present invention, when in use, the fiber is unloaded through the silo, and the fiber is transmitted through the first roller and the second roller. During the transmission process, the fiber falls onto the forming conveyor belt through the gap between the first roller and the second roller, and the forming conveyor belt is driven by the second driving motor to form a slab and then is hot-pressed in the forming device;

[0016] 2. In the present invention, when the first roller and the second roller are rotating, the second driving motor drives the rotating shaft of one of the first rollers to rotate, and the first roller realizes the same direction rotation of multiple first rollers through the cooperation between the third sprocket wheel and the third chain on the roller extending on the right side of the frame body. At the same time, the third driving motor drives the rotating shaft of one of the second rollers to rotate, and the second roller is connected with the second chain through the second sprocket wheel extending on the rotating shaft on the left side of the frame body, so as to realize the synchronous rotation of multiple second rollers. In this way, when the fiber is transmitted through the first roller and the second roller, the rotation direction of the first roller and the second roller set at intervals can be adjusted, thereby meeting different paving needs;

[0017] 3. In the present invention, after the fiber passes through the first roller and the second roller and falls onto the forming conveyor belt, the bottom of the forming conveyor belt contacts the roller. In this way, when the weight of the fiber on the forming conveyor belt is greater than the elasticity of the spring, the slider drives the extension block to slide downward along the slide rod. When the spring is compressed, the slider drives the adjustment plate inside the silo to slide downward through the L-shaped connecting rod. When the L-shaped connecting rod pulls the mounting seat downward, the adjustment plate passes through the first C-shaped block and slides obliquely along the second C-shaped block. At the same time, the second C-shaped block installed on the mounting seat slides backward along the second slide rail at the bottom of the adjustment plate, thereby realizing the adjustment of the distance between the end of the adjustment plate away from the first C-shaped block and the inner wall of the silo, thereby effectively adjusting the fiber unloading speed and ensuring that the weight of the slab on the forming conveyor belt is controlled within a controllable range.

[0030] By adopting the above technical solution, when in use, the fibers are discharged through the hopper 30, and the fibers are transmitted through the first roller 21 and the second roller 22. During the transmission process, the fibers fall onto the forming conveyor belt 11 through the gap between the first roller 21 and the second roller 22, and are driven by the second drive motor 12 to form a slab and then hot-pressed in the forming device for transmitting the formed slab.

[0031] In this embodiment, the rotating shafts of the plurality of second rotating rollers 22 extend to the right side of the frame 20; the rotating shafts are all equipped with second sprockets 25; the plurality of second sprockets 25 are connected by second chains 24; any rotating shaft of the plurality of second rotating rollers 22 is fixedly installed with the third driving motor 26; the third driving motor 26 is arranged diagonally with the second driving motor 23;

[0033] By adopting the above technical solution, when the first roller 21 and the second roller 22 rotate, the second drive motor 23 drives the shaft of one of the first rollers 21 to rotate, and the first roller 21 realizes the same direction rotation of multiple first rollers 21 through the cooperation between the third sprocket 28 and the third chain 27 on the roller extending on the right side of the frame 20.

[0035] The bottom of the frame 20 is fixedly mounted to the transmission frame 10 via a plurality of support rods 15;

[0036] By adopting the above technical solution, after the fiber falls onto the forming conveyor belt 11 through the first roller 21 and the second roller 22, the bottom of the forming conveyor belt 11 contacts the roller 110. In this way, when the weight of the fiber on the forming conveyor belt 11 is greater than the elasticity of the spring 111, the slider 17 drives the extension block 18 to slide downward along the slide rod 19. When the spring 111 is compressed, the slider 17 drives the adjustment plate 31 inside the silo 30 to slide downward through the L-shaped connecting rod 33. When the L-shaped connecting rod 33 pulls the mounting seat 37 downward, the adjustment plate 31 slides obliquely along the second C-shaped block 34 through the first C-shaped block 35. At the same time, the second C-shaped block 34 installed on the mounting seat 37 slides backward along the second slide rail 36 at the bottom of the adjustment plate 31, thereby realizing the adjustment of the distance between the end of the adjustment plate 31 away from the first C-shaped block 35 and the inner wall of the silo 30, thereby effectively adjusting the fiber unloading speed and ensuring that the weight of the slab on the forming conveyor belt 11 is controlled within a controllable range.

[0037] The working principle of the present invention is as follows: when in use, the fiber is discharged through the hopper 30, and the fiber is transmitted through the first roller 21 and the second roller 22. During the transmission process, the fiber falls onto the forming conveyor belt 11 through the gap between the first roller 21 and the second roller 22, and the forming conveyor belt 11 is driven by the second driving motor 12 to form a slab and then is hot-pressed in the forming device;

[0038] When the first roller 21 and the second roller 22 rotate, the second drive motor 23 drives the shaft of one of the first rollers 21 to rotate. The first roller 21 cooperates with the third sprocket 28 and the third chain 27 on the roller extending on the right side of the frame 20 to realize the same-direction rotation of multiple first rollers 21. At the same time, the third drive motor 26 drives the shaft of one of the second rollers 22 to rotate. The second roller 22 cooperates with the second chain 24 through the second sprocket 25 extending on the shaft on the left side of the frame 20 to realize the synchronous rotation of multiple second rollers 22. In this way, when the fiber is transmitted through the first roller 21 and the second roller 22, the rotation direction of the first roller 21 and the second roller 22 set at intervals can be adjusted to meet different paving needs.

[0039] After the fiber falls onto the forming conveyor belt 11 through the first roller 21 and the second roller 22, the bottom of the forming conveyor belt 11 contacts the roller 110. In this way, when the weight of the fiber on the forming conveyor belt 11 is greater than the elasticity of the spring 111, the slider 17 drives the extension block 18 to slide downward along the slide rod 19. When the spring 111 is compressed, the slider 17 drives the adjustment plate 31 inside the silo 30 to slide downward through the L-shaped connecting rod 33. When the L-shaped connecting rod 33 pulls the mounting seat 37 downward, the adjustment plate 31 slides obliquely along the second C-shaped block 34 through the first C-shaped block 35. At the same time, the second C-shaped block 34 installed on the mounting seat 37 slides backward along the second slide rail 36 at the bottom of the adjustment plate 31, thereby realizing the adjustment of the distance between the end of the adjustment plate 31 away from the first C-shaped block 35 and the inner wall of the silo 30, thereby effectively adjusting the fiber unloading speed and ensuring that the weight of the slab on the forming conveyor belt 11 is controlled within a controllable range.
