Technical Field
[0001] The invention relates to the technical field of extruded board production, in particular to a thickness-adjustable extrusion device for producing extruded boards. Background Art
[0002] Extruded board is a material that is continuously extruded and foamed through a special process. The hard film formed on its surface is uniform and flat, and the completely closed-cell foam inside is continuous and uniform, forming a honeycomb structure. Therefore, it has the characteristics of high pressure resistance, light weight, non-water absorption, airtightness, wear resistance, and non-degradation. Due to the characteristics of extruded board, it is also widely used. At present, extruded board is widely used for wall insulation, insulation of flat concrete roofs and steel structure roofs, as well as moisture-proof insulation in low-temperature storage floors, parking platforms, airport runways, highways and other fields.
[0003] In existing extruded board production lines, thickness adjustment typically relies on stopping the machine to replace gaskets or manually adjusting the mold. This process is cumbersome and affects continuous operation. Furthermore, if additional processing is required during the production line, parameters must be adjusted to reflect the thickness change, leading to production errors. Therefore, a thickness-adjustable extrusion device is needed for extruded board production. Summary of the Invention

[0014] Preferably, an extruder is further included, wherein the output end of the extruder is located at the rear end of the side close to the two extrusion rollers for extruding an extruded board.
[0015] Working principle: When producing extruded board, the extruded board extruded from the extrusion port of the extruder is squeezed into the adjacent side of two extrusion rollers, and the two meshing wheels connected to the extrusion rollers driven by the bidirectional screw are meshed and rotated in opposite directions, so that the two extrusion rollers suck the extruded board, and the extruded board is squeezed by the two extrusion rollers to be squeezed into a suitable thickness and fall onto the rear conveyor belt. The extruded board is transported by the rear conveyor belt. During the transportation, the extruded board passes through the bottom side of the embossing roller when it is not completely cooled. The embossing roller forms embossed or striped grooves on its surface, and when passing through the bottom side of the cold air nozzle, the cold air nozzle cools and shapes the surface of the extruded board by delivering cooling air, causing it to solidify and form. When it is delivered to the cutting table, part of the entire extruded board is placed on the surface of the cutting table, and then the cutting work is carried out. The synchronous wheel 2 connected by the bidirectional screw through the synchronous belt transmits power to the reciprocating screw through two meshing bevel gears, so that the reciprocating screw drives the cutting table to drive the top side of the extruded board to move back and forth. During this period, The displaced cutting table drives the lifting frame on the top side to move together, so that the lifting frame rises and falls through the guide groove of the guide rail. When the cutting table moves forward, the lifting frame cooperates with the structure including the positioning pressure plate on the bottom side to descend, so that the positioning pressure plate presses the entire extruded board to fix it to prevent deviation. After pressing the extruded board, the cutting frame driven by the electric guide rail moves to the position of the extruded board, and the transmission wheel driven by the motor 3 rotates, driving the cutting wire to move, so that the high-speed displacement cutting wire contacts the extruded board, and under the synchronous drive of the displaced electric guide rail, continuously cuts the extruded board, so that the entire extruded board is cut, and the cut parts are placed on the conveyor belt at the front end. After the cutting table continues to move for a distance, the positioning pressure plate releases its fixation, so that the conveyor belt at the front end transports the cut extruded board through the conveyor belt at the front end for unloading. The cutting table resets, and repeats the above steps to continue cutting and unloading. During the cutting process, the chip suction frame of the external vacuum fan follows the cutting direction to recover the chips of the cut part; When the thickness of the extruded board needs to be adjusted, the second motor drives the first screw to rotate. The rotating screw drives the second screw to rotate synchronously through the synchronous belt and the synchronous wheel. The rotating screw drives the sliding frame to move. The sliding frame moves together with one of the extrusion rollers. After the displacement of the extrusion roller, the distance between the extrusion roller and the other extrusion roller can be adjusted, so that the thickness of the extruded board after the two extrusion rollers are pressurized and formed can be adjusted. The rotating screw performs the following transmission: The threaded sleeve driven by the second thread of the screw moves at the bottom end of the shell to adjust the height of the embossing roller on its bottom side. After the thickness of the extruded board is adjusted, the height is adjusted synchronously to ensure that the embossing and grooving depth specifications of the embossing roller remain unchanged to adapt to the thickness change of the extruded board. The rotating screw 2 meshes with the gear through the teeth on its outer wall, and rotates the gear ring connected to the threaded disk through the gear meshing transmission, so that the part of the displacement frame sliding on the gear ring moves accordingly along the rotation of the thread, so that the spacing between the multiple displacement frames connected to the cold air nozzles can be changed to adapt to the expansion and contraction of the width after the thickness of the extruded board changes; The displaced threaded sleeve will synchronously drive the connecting frame connected to it to displace, so that the connecting frame will drive the pressure piston connected to it to displace synchronously inside the cylinder three, so that the pressure in the two oil chambers inside the sealed cylinder three will change, and the ratio of hydraulic oil between cylinder one and cylinder two and the two oil chambers will change through the pipeline, so that the pressure piston one inside the cylinder one will lift and lower the chip suction frame together, and the pressure piston two inside the cylinder two will drive the positioning pressure plate to lift and lower, so as to synchronously adapt to the change in the thickness of the extruded board, maintain the optimal chip suction distance of the chip suction frame and the ability of the positioning pressure plate to stably press the positioning extruded board.
[0016] The present invention provides a thickness-adjustable extrusion device for producing extruded boards. It has the following beneficial effects: 1. The present invention realizes dynamic adjustment of the thickness of the extruded board during the production process without stopping the machine for manual mold adjustment, which simplifies the adjustment process and does not affect continuous operation. At the same time, the data of the additional embossing and grooving process and the cooling and molding process can also be adjusted synchronously to adapt to the width and embossing depth requirements after the thickness of the extruded board changes, ensuring the stability of product quality, improving production flexibility and efficiency, and reducing production errors and downtime caused by thickness adjustment.
[0017] 2. The present invention has the capabilities of extrusion, thickness adjustment, embossing, segmentation and cooling molding through an integrated design, which greatly improves the production capacity of the extrusion equipment to improve the extrusion production efficiency and uniformity.
[0018] 3. The present invention realizes stable cutting of extruded boards. When the extruded boards are transported to the cutting table, the positioning frame is triggered synchronously to position and fix the extruded boards before cutting, so as to prevent deviation during the cutting process. The cutting part is then scraped back along the cutting direction, which reduces the scrap residue in the working area. The scraps can be recycled for reproduction, thus reducing production costs.

The extruder 2 is a basic extrusion device commonly seen on the market. It is equipped with basic components and optimized components including an auger, a heating structure, a die head, etc. that can be used for extrusion production of extruded boards, so that it can stably extrude extruded boards.
[0023] Please see the attached Figure 2 and attached Figure 3 , used to extrude the extruded sheet and adjust its thickness of the extrusion roller 3, the number of extrusion rollers 3 is two, the two extrusion rollers 3 are adjusted in spacing by an adjusting component, and are driven to rotate by a power component to extrude the extruded sheet to form a suitable thickness, the adjusting component includes a screw 1 5 rotatably connected to the rear end of the top side of the frame body 1, the bottom end of the screw 1 5 is threadedly connected to a sliding frame 4, both sides of the sliding frame 4 are slidably connected to the frame body 1, one of the extrusion rollers 3 is rotatably connected to the bottom side of the sliding frame 4, the other extrusion roller 3 is rotatably connected to the bottom of the rear end of the frame body 1, the screw 1 5 is driven by a motor 2 on the top side, one of the synchronous wheels 10 is fixedly connected to the top of the outer wall of the screw 1 5, the power component includes a meshing wheel 6 fixedly connected to the left side of the extrusion roller 3, a bidirectional screw 7 is rotatably connected to the left side of the rear end of the frame body 1, the top side of the bidirectional screw 7 is driven by a motor 2, the meshing wheel 6 and the bidirectional screw 7 are meshed with each other, and one of the synchronous wheels 20 is fixedly connected to the bottom side of the bidirectional screw 7; Specifically, when producing extruded boards, the extruded boards extruded from the extrusion port of the extruder 2 are squeezed into the adjacent sides of the two extrusion rollers 3, and the bidirectional screw 7 driven by the motor 1 meshes with the two meshing wheels 6 connected to the extrusion rollers 3 and rotates in opposite directions, so that the two extrusion rollers 3 suck in the extruded boards, so that the extruded boards are squeezed by the two extrusion rollers 3, and the extruded boards are squeezed into a suitable thickness and fall onto the conveyor belt 35 at the rear end. When the thickness specifications of the extruded boards need to be adjusted, the motor 2 drives the screw 1 5 to rotate, and the rotating screw 1 5 is synchronously driven by the synchronous belt and the synchronous wheel 10 to rotate together, so that the rotating screw 1 5 drives the sliding frame 4 to move, and the sliding frame 4 cooperates with one of the extrusion rollers 3 to move together, so that after the extrusion roller 3 is displaced, the distance between it and the other extrusion roller 3 can be adjusted, so that the thickness specifications of the extruded boards after pressure molding by the two extrusion rollers 3 can be adjusted.
[0024] Please see the attached Figure 4, shell 8, the shell 8 is fixedly connected to the middle end of the top side of the frame 1, and the middle end of the bottom side of the shell 8 is provided with an embossing roller 12 for embossing and grooving the uncooled extruded plate. The front end of the bottom side of the shell 8 is provided with a plurality of cold air nozzles 36 for assisting the rapid cooling and forming of the extruded plate. The embossing roller 12 is lifted and lowered by a lifting assembly to adapt to the thickness change of the extruded plate. The lifting assembly drives the offset assembly through the meshing gear 15 to adjust the spacing of the plurality of cold air nozzles 36 to adapt to the width change after the thickness of the extruded plate changes. The lifting assembly is connected to the adjustment assembly through a synchronous belt and a synchronous wheel 10; Specifically, while the extruded board is being transported by the conveyor belt 35 at the rear end, the extruded board is not completely cooled, and in this state, embossing and grooving can be performed. In the exterior wall insulation system, the outer surface of the extruded board, that is, the side in contact with the air, usually needs to be embossed or grooved to enhance the adhesion with the plaster layer or the finishing layer, while the inner surface, the side in contact with the wall, needs to be bonded with the wall mainly by relying on an interface agent and bonding mortar, and does not require embossing or grooving. It passes through the bottom side of the embossing roller 12 and is rolled by the embossing roller 12 to form embossed or striped grooves on its surface. When passing through the bottom side of the cold air nozzle 36, the cold air nozzle 36 cools and shapes the surface of the extruded board by delivering cooling air, causing it to solidify and form.
[0025] Please see the attached Figure 4 , Attachment Figure 5 and attached Figure 7 The lifting assembly includes a screw rod 2 9 rotatably connected to the center of the housing 8, the top side of the screw rod 2 9 is fixedly connected to another synchronous wheel 10, the outer wall of the bottom end of the screw rod 2 9 is threadedly connected to a threaded sleeve 11, the outer wall of the threaded sleeve 11 is slidably connected to the middle end of the bottom side of the housing 8, and the middle end of the screw rod 2 9 is meshed with one side of the gear 15 through the teeth arranged around it; Specifically, the threaded sleeve 11, which is driven by the screw 2 9, is displaced at the bottom end of the shell 8 to adjust the height of the embossing roller 12 on its bottom side so that it can follow the thickness adjustment of the extruded board and then adjust the height synchronously to ensure that the embossing and grooving depth specifications of the embossing roller 12 remain unchanged to adapt to the thickness change of the extruded board.
[0026] Please see the attached Figure 4 -Attached Figure 6 The offset assembly includes a threaded disc 13 rotatably connected to the bottom end of the shell 8 and a displacement frame 16 slidably connected to the front end of the bottom side of the shell 8. The top side of the threaded disc 13 is fixedly connected to a gear ring 14. The inner periphery of the gear ring 14 is meshed with the other side of the gear 15. The bottom side of the threaded disc 13 is provided with a thread. The top side of the displacement frame 16 is slidably connected to the inside of the thread. The bottom side of the displacement frame 16 is fixedly connected to the cold air nozzle 36. The input end of the cold air nozzle 36 is externally connected to a pipe for providing cooling air. The pipe provides cooling gas with a lower temperature through a cooling fan. Specifically, due to the change in the thickness of the extruded board, the amount of extrusion received by the two extrusion rollers 3 each time they extrude remains constant, so that the extruded board will extend to both sides after being extruded, and the change in thickness will affect the extension amount on both sides, and then affect the width after extrusion. After the rotating screw 2 9 passes through the teeth of its own outer wall to engage the gear 15, the gear ring 14 connected to the threaded disk 13 through the gear 15 engagement transmission rotates, so that the part of the displacement frame 16 that slides in the gear ring 14 along the thread rotation is displaced accordingly, so that the spacing between multiple displacement frames 16 can be changed to adapt to the extension and shortening of the width after the thickness of the extruded board changes.
[0027] Please see the attached Figure 8 and attached Figure 9 , the cutting table 17, as the cutting area of the extruded board, is located on the side close to the two conveyor belts 35, and the cutting table 17 transmits the displacement of the extruded board through the synchronous conveyor belt 35 of the displacement component. The displacement component is connected to the power component through the synchronous belt and the synchronous wheel 20, and triggers the positioning frame on the top side of the cutting table 17 by displacement to position and fix the extruded board, and the extruded board is divided and the chips are sucked by the cutting component on the rear side of the cutting table 17.

The bidirectional screw 7 is connected to the synchronous wheel 20 through the synchronous belt, and the power is transmitted to the reciprocating screw 18 by two meshing bevel gears, so that the reciprocating screw 18 drives the cutting table 17 to drive the extruded board on the top side to move back and forth. During this period, the displaced cutting table 17 drives the lifting frame 26 on the top side to move together, so that the lifting frame 26 rises and falls through the guide groove of the guide rail 25. When the cutting table 17 moves forward, the lifting frame 26 cooperates with the structure on the bottom side including the positioning pressure plate 27 to descend, so that the positioning pressure plate 27 presses the entire extruded board to fix it to prevent displacement.
[0028] Please see the attached Figure 10 and attached Figure 11The cutting assembly includes a cutting frame 22 that is horizontally displaced on the rear side of the cutting table 17 through an electric guide rail 21. The top and bottom ends of the cutting frame 22 are rotatably connected to two transmission wheels 23. The four transmission wheels 23 are provided with cutting wires for cutting extruded boards. The outer wall of the cutting frame 22 is provided with a chip suction frame 24. The input end of the chip suction frame 24 is connected to an exhaust fan for exhausting air through a pipe.
[0029] Specifically, when cutting the extruded board, the cutting frame 22 driven by the electric guide rail 21 is displaced toward the position of the extruded board, and the transmission wheel 23 driven by the motor 3 is rotated to drive the cutting wire to displace, so that the high-speed displaced cutting wire contacts the extruded board, and is continuously cut under the synchronous drive of the displaced electric guide rail 21, so that the entire extruded board is divided, and the divided parts are placed on the conveyor belt 35 at the front end. During this period, the chip suction frame 24 of the external vacuum pump follows the cutting direction to recover the debris of the cut part, thereby reducing the debris residue in the working area and reproducing by recovering the debris to reduce production costs.

When the lifting component is lifted, the pressure piston 33 is synchronously displaced by the connecting frame 34, and the top side of the pressure piston 33 is fixedly connected to the connecting frame 34; Please see the attached Figure 10 , Attachment Figure 12 and attached Figure 13 The distribution assembly includes a cylinder 1 28 fixedly connected to both sides of the cutting frame 22 and a cylinder 2 30 fixedly connected to the middle end of the lifting frame 26.
