Description

Technical Field

[0001] This invention relates to the field of laminating technology, specifically to a laminating machine for producing external wall insulation boards. Background Technology

[0002] The key to the lamination process lies in the precise and uniform control of pressure and temperature. Pressure needs to rise steadily, be highly controlled, and be uniform in all directions; heating requires speed and uniformity to ensure that the adhesive materials (such as adhesives and foam concentrates) can fully cure. Traditional laminators mostly use dispersed hydraulic cylinders or pneumatic cylinders to drive the pressure plate, resulting in limited pressure points, making it difficult to provide comprehensive and uniform pressure when pressing large-sized sheets. In terms of heating methods, contact heat conduction may be inefficient and have heating lag; while single-sided heating will lead to uneven heating of the board. After the insulation board is laminated, the platen temperature is high, and the board may stick to the platen. Manual material handling poses a risk of burns and is inefficient. Based on these challenges, current technological development mainly revolves around the following directions. In addition to the air pressure equalization and fluid pressure equalization solutions shown in the table, there are also patents that use the synchronous movement of threaded rods and sleeves to achieve precise alignment and stable lamination of materials to improve accuracy and pursue faster and more uniform heating methods. As mentioned, the platen itself generates an induced current and heats up by using a magnetic field, which fundamentally changes the heat transfer path, resulting in fast heating speed and less lag. As mentioned, heating chambers are set in the upper and lower platens, and double-sided heating is carried out by circulating hot air, which improves uniformity. If a biomass combustion furnace is used, stable automated heating can be achieved while saving energy. The development direction is to integrate continuous production lines with automatic conveying, positioning, lamination, ejection, cutting and stacking. For example, automatic conveying and initial lamination of the insulation layer and the base layer can be achieved through motors, gears, and rotating rollers; or a specially designed automatic ejection mechanism can replace manual material handling.

[0003] CN119820977B A laminator for producing exterior wall insulation boards supports the core board from the bottom side using a support plate, reducing the squeezing force of the adjusting frame and connecting plate on the side of the core board, thereby reducing the deformation of the core board during transportation and making the edge of the core board flush with the edge of the substrate.

[0004] However, this equipment prioritizes the fixing method of the boards, which can easily lead to deviations and misalignment when gluing multi-layer laminates. Furthermore, the lack of corresponding compression treatment between the boards results in poor bonding quality. Summary of the Invention

[0005] To solve the above technical problems, the present invention is achieved through the following technical solution: an external wall insulation board production laminator, including a fixed base, a conveying device fixedly connected to the top of the fixed base, an adhesive applicator fixedly connected to the top of the fixed base at one side of the conveying device, a pressing device fixedly connected inside the adhesive applicator, and the pressing device being positioned above the conveying device. The pressing device includes a fixed base, the bottom of which is fixedly connected to the fixed end of an electric telescopic rod, the movable end of which is fixedly connected to a movable base, the bottom of which is fixedly connected to the movable end of a forked spring rod, the fixed end of which is fixedly connected to a lowering base, the bottom of which is fixedly connected to an extrusion plate, the top of which is slidably connected to a heating ring, which is positioned below the movable base, the side of which is fixedly connected to the side of an adhesive applicator via a bracket, and the heating ring is positioned above the conveying device.

[0006] Preferably, the extrusion plate includes an extrusion base plate, with a sliding inner groove at the top center and a sliding outer groove on one side of the top of the extrusion base plate. A discharge groove is formed at the bottom of the extrusion base plate. The top of the extrusion base plate is fixedly connected to the bottom of the descending seat. The extrusion base plate is positioned above the conveying device. The sheet material is conveyed to the top of the conveying device via an external conveying device and fixed by corresponding components of the conveying device. The glue applicator is activated, rotating to apply glue to the top of the sheet material. After the glue applicator has applied all the glue, the sheet material is covered by an external transfer device. The sheet material is then covered under the guidance of the conveying device. Activating the electric telescopic rod causes its movable end to descend, which in turn causes the movable end of the forked spring rod to descend. The movable end of the forked spring rod then causes its fixed end to descend elastically. The descent of the fixed end of the forked spring rod causes the lowering seat to descend, which in turn causes the extrusion plate to descend. The extrusion plate then presses down on the top of the sheet material. The distributed arrangement of the forked spring rods evenly applies downward pressure to the top of the extrusion plate, thus stabilizing the adhesive layer between the sheets. The uniform downward pressure evenly fixes the adhesive layer between the sheets. After the pressing is complete, a heating ring heats and cures the adhesive layer on the top of the extrusion plate, thereby facilitating the stable adhesive coverage quality between the sheets.

[0007] Preferably, the heating ring includes a sliding sleeve, a connecting frame fixedly connected to the side of the sliding sleeve, a heating inner ring fixedly connected to the bottom of the connecting frame, and a heating outer ring fixedly connected to the top of the connecting frame at a position on one side of the heating inner ring. A sliding post is fitted and slidably connected to the side of the sliding sleeve, and a spring is fixedly connected to the top of the sliding sleeve. The end of the spring away from the sliding sleeve is fixedly connected to the side of the sliding post through a fixing ring. The top of the sliding post is fixedly connected to the bottom of the heating inner ring. The heating inner ring is disposed inside the sliding inner groove, and the heating outer ring is disposed within the sliding inner groove. Inside the sliding outer groove, the sliding inner groove and the sliding outer groove are designed to facilitate the embedding of the heating inner ring and the heating outer ring, thereby uniformly heating the main body of the extrusion base plate. During the extrusion of the sheet material, the edge of the adhesive is specifically heated, which facilitates the fixation of the adhesive layer between the sheets. Driven by the electric telescopic rod, the moving seat drives the bifurcated spring rod to descend. When the bifurcated spring rod descends, it drives the descending seat to descend, which in turn drives the extrusion base plate to descend. The discharge groove facilitates the overflow of adhesive from the edge of the sheet material, thereby facilitating the uniform application of adhesive between the sheets and reducing air bubbles and glue residue. To address the issue of uneven water extrusion and ensure stable adhesive application quality while the sheet material is fixed, the system works as follows: When the moving seat descends, it causes the sliding column to descend as well. The spring is initially positioned to pull up the sliding sleeve. During the descent of the sliding column, the sliding column, in turn, causes the spring to descend. After the extrusion base plate contacts the sheet material, the sliding column, along with the spring, descends, causing the sliding sleeve to descend. The sliding sleeve, in turn, causes the connecting frame to descend, which in turn causes the inner and outer heating rings to descend. After the extrusion base plate extrudes the sheet material, the components are embedded within the inner and outer sliding grooves, thus ensuring the extrusion base plate... Internal heating cures the adhesive layer on the top of the board. The enveloping design of the inner and outer heating rings compresses the area around the descending seat, concentrating heating and curing at the stress point. This facilitates curing of the adhesive layer from the stress point. Simultaneously, as the sliding column descends, it drives the spring to descend, which in turn drives the sliding sleeve to descend. The sliding sleeve then drives the connecting frame to descend. Under the elastic force of the spring, the sliding sleeve continues to descend and adds elasticity, thus facilitating auxiliary downward pressure on the top of the extrusion base plate and curing the adhesive between the board layers.

[0008] Preferably, the glue-applying rod includes a rotating base, a drive motor is fixedly connected to the side of the rotating base, a rotating frame is fixedly connected to the drive shaft of the drive motor, a glue-applying roller is slidably connected to the side of the rotating frame, a telescopic rod is sleeved and rotatably connected to the side of the glue-applying roller, a feed connector is rotatably connected to the side of the telescopic rod, the bottom of the rotating base is fixedly connected to the top of the fixed base through a bracket, and the bottom of the glue-applying roller contacts the top of the glue-applying roller.

[0009] Preferably, the glue-applying roller includes a sliding base, a sliding strip fixedly connected to the side of the sliding base, a glue-applying motor fixedly connected to the inner side of the sliding base, a spring rod fixedly connected to the top of the sliding base, a glue-applying cylinder rotatably connected to the side of the sliding base, a glue-applying cylinder fixedly connected to the drive shaft of the glue-applying motor on the side of the glue-applying cylinder, a glue outlet groove formed on the side of the glue-applying cylinder, and a feed pipe connected to the end of the glue-applying cylinder away from the sliding base. The feed pipe passes through the movable end of the telescopic rod and communicates with the side of the telescopic rod. The side of the rotating base... A sliding groove adapted to the sliding bar is provided. The sliding base is located on the side of the rotating seat and slidably connected to the side of the rotating seat. The side of the spring rod is fixedly connected to the side of the rotating seat through a bracket. A feed inlet is connected, and external glue is introduced into the interior of the telescopic rod along the feed inlet. The glue then enters the interior of the feed pipe along the telescopic rod, flows along the inside of the glue coating cylinder, and leaks out along the inner wall of the glue outlet groove. The glue is extruded along the glue outlet groove. The drive motor is started, and the drive shaft of the drive motor drives the rotating frame to rotate. The rotation of the rotating frame drives the sliding base. The sliding base moves along the side of the rotating frame, guided by a sliding bar. This movement of the sliding base moves the spring rod. After the board is fixed, the rotating frame moves the sliding base to the top of the board, then the glue-applying motor is activated. The rotating motor drives the glue-applying cylinder to rotate, which moves along the top of the board. Driven by the motor, the glue-applying cylinder applies glue to the top of the board. It also moves in the opposite direction to the movement of the sliding base, applying glue to the top of the board. During this movement, the bottom of the glue-applying cylinder contacts the top of the board, receiving pressure from the board and moving along the side of the rotating frame. This movement of the sliding base moves the spring rod, which then resets the sliding base, allowing the glue-applying cylinder to press against the top of the board, ensuring even glue application and improving adhesion between boards.

[0010] Preferably, the conveying device includes a fixed side plate, a movable roller is rotatably connected to the inner wall side of the fixed side plate, a support plate is fixedly connected to the portion of the inner side of the fixed side plate located on one side of the movable roller, a limit roller is fixedly connected to the inner wall side of the fixed side plate located on one side of the movable roller, the bottom of the fixed side plate is fixedly connected to the top of the fixed base, and the extrusion base plate is positioned above the support plate.

[0011] Preferably, the limiting roller includes an auxiliary roller, and a limiting plate is fixedly connected to the side of the auxiliary roller. The side of the auxiliary roller is rotatably connected to the inner wall of the fixed side plate. The sheet material enters the top of the support plate through an external conveying device. When the extrusion base plate presses down, the pressure of the extrusion base plate is applied to the top of the sheet material. The downward pressure is transmitted through the sheet material to the top of the moving roller. The sheet material enters the top of the moving roller through an external conveying device. The support plate is designed to bear the downward pressure on the sheet material and avoid deformation of the sheet material caused by hard contact between the top of the moving roller and the bottom of the sheet material. When the sheet material moves into the top of the moving roller, the auxiliary roller is activated. The rotation of the auxiliary roller drives the limiting plate to rotate. The rotation of the limiting plates on both sides limits the side of the sheet material, thereby facilitating the fixing of the sheet material's position. The sheet material is stably fixed on the top of the moving roller and the side of the limiting plate, thereby facilitating the pressing of the extrusion base plate and the extrusion of the sheet material.

[0012] This invention provides a laminating machine for producing external wall insulation boards. It has the following beneficial effects: 1. This exterior wall insulation board production laminator is equipped with a moving base. After the boards are conveyed to the designated position by an external conveying device, they are fixed by corresponding components. Then, the adhesive applicator rotates, applying adhesive to the board surface. After adhesive application, the external conveying device covers another board on top. Next, the equipment starts the pressing program, causing the extrusion plate to descend smoothly, applying pressure to the stacked boards. Through a distributed elastic structure, the pressure is evenly transmitted to the entire board, promoting uniform distribution and stability of the adhesive layer between the boards. After maintaining pressure for a period of time, the heating ring is activated to heat and cure the adhesive layer, thereby improving the bonding quality between the boards.

[0013] 2. This exterior wall insulation board production laminator is equipped with an inner heating ring. The built-in heating ring design allows for uniform heating of the pressing area. During the pressing process, the adhesive edges receive targeted heating, aiding in adhesive layer fixation. As the extruder presses down, adhesive overflows from the discharge grooves at the board edges, promoting even adhesive layer spread between boards and reducing air bubbles and uneven distribution. During pressing, the heating ring descends synchronously with the pressing plate, providing wrap-around heating to the adhesive area after pressing, promoting adhesive layer curing from the point of stress. Elastic elements provide continuous auxiliary pressure in the later stages of pressing, further promoting adhesive layer fixation and bonding between boards.

[0014] 3. This exterior wall insulation board production laminator is equipped with a feeding pipe. Adhesive is conveyed to the coating cylinder through the feeding system and extruded from the adhesive outlet. A drive motor moves the coating mechanism along the board surface, while simultaneously driving the coating cylinder to rotate, ensuring the adhesive is evenly applied to the board. During the coating process, the coating cylinder remains in contact with the board surface. An elastic device allows the coating cylinder to adapt to the board surface, maintaining stable coating pressure. This ensures a uniform adhesive coating on the board, facilitating subsequent bonding between boards.

[0015] 4. This external wall insulation board production laminator is equipped with a support plate. The boards are transported to the support plate by an external conveying device. When the pressure plate presses down, the pressure is transmitted through the boards to the moving rollers below. The support structure helps to distribute the pressure and prevent localized deformation of the boards. After the boards are in place, the auxiliary rollers on both sides drive the limiting plates to rotate, adjusting and fixing the position of the boards from the side, ensuring they remain aligned during the pressing process. This provides stable support and positioning for the boards, facilitating uniform pressing and promoting better adhesion between the boards. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] For the first embodiment, please refer to... Figures 1-2 The present invention provides a technical solution: an external wall insulation board production laminator, including a fixed base 1, a conveying device 2 fixedly connected to the top of the fixed base 1, an adhesive applicator 3 fixedly connected to the top of the fixed base 1 at one side of the conveying device 2, a pressing device 4 fixedly connected inside the adhesive applicator 3, and the pressing device 4 being located above the conveying device 2. The pressing device 4 includes a fixed base 401. The fixed end of an electric telescopic rod 402 is fixedly connected to the bottom of the fixed base 401. The movable end of the electric telescopic rod 402 is fixedly connected to a movable base 403. The movable end of a forked spring rod 404 is fixedly connected to the bottom of the movable base 403. A descending base 405 is fixedly connected to the fixed end of the forked spring rod 404. A pressing plate 406 is fixedly connected to the bottom of the descending base 405. A heating ring 407 is slidably connected to the top of the pressing plate 406. The heating ring 407 is located below the movable base 403. The side of the fixed base 401 is fixedly connected to the side of the glue applicator 3 through a bracket. The heating ring 407 is located above the conveying device 2.

[0020] The sheet material is conveyed to the top of conveyor 2 via an external conveying device and fixed by corresponding components of conveyor 2. The glue applicator 3 is then activated, rotating to apply glue to the top of the sheet material. After the glue applicator 3 has applied all the glue, it is covered by an external transfer device. Once the sheet material is covered under the guidance of conveyor 2, the electric telescopic rod 402 is activated. The movable end of the electric telescopic rod 402 lowers the moving seat 403, which in turn lowers the movable end of the forked spring rod 404. The movable end of the forked spring rod 404 then lowers the forked spring rod 404. The fixed end elastically descends, and the downward movement of the fixed end of the forked spring rod 404 drives the descending seat 405 to descend. The downward movement of the descending seat 405 drives the extrusion plate 406 to descend. The extrusion plate 406 extrudes the top of the board, and the distributed arrangement of the forked spring rod 404 evenly applies downward pressure to the top of the extrusion plate 406, thereby stabilizing the adhesive layer between the boards. The adhesive layer is evenly fixed between the boards by the uniform downward pressure. After the downward pressure is completed, the heating ring 407 heats and cures the adhesive layer on the top of the extrusion plate 406, thus facilitating the stabilization of the adhesive coverage quality between the boards.

[0021] For the second embodiment, please refer to... Figures 1-4 Based on the first embodiment, the present invention provides a technical solution: the extrusion plate 406 includes an extrusion base plate 4061, a sliding inner groove 4062 is provided at the top center of the extrusion base plate 4061, a sliding outer groove 4063 is provided at the top of the extrusion base plate 4061 on one side of the sliding inner groove 4062, a discharge groove 4064 is provided at the bottom of the extrusion base plate 4061, the top of the extrusion base plate 4061 is fixedly connected to the bottom of the descending seat 405, and the extrusion base plate 4061 is positioned above the conveying device 2.

[0022] The heating ring 407 includes a sliding sleeve 4071, a connecting frame 4072 fixedly connected to the side of the sliding sleeve 4071, a heating inner ring 4073 fixedly connected to the bottom of the connecting frame 4072, and a heating outer ring 4074 fixedly connected to the top of the connecting frame 4072 at a position on one side of the heating inner ring 4073. A sliding column 4075 is fitted and slidably connected to the side of the sliding sleeve 4071, and a spring 4076 is fixedly connected to the top of the sliding sleeve 4071. One end of the spring 4076 away from the sliding sleeve 4071 is fixedly connected to the side of the sliding column 4075 through a fixing ring. The top of the sliding column 4075 is fixedly connected to the bottom of the heating inner ring 4073. The heating inner ring 4073 is disposed inside the sliding inner groove 4062, and the heating outer ring 4074 is disposed inside the sliding outer groove 4063.

[0023] The sliding inner groove 4062 and the sliding outer groove 4063 facilitate the embedding of the heating inner ring 4073 and the heating outer ring 4074, thereby uniformly heating the main body of the extrusion base plate 4061. During the extrusion of the sheet material, the edges of the adhesive are specifically heated, facilitating the fixation of the adhesive layer between the sheets. Driven by the electric telescopic rod 402, the moving seat 403 lowers the forked spring rod 404. The lowering of the forked spring rod 404 causes the lowering seat 405 to descend, which in turn lowers the extrusion base plate 4061. The discharge groove 4064... The design facilitates glue overflow from the edges of the board, ensuring even glue application between boards and reducing issues like air bubbles and uneven glue extrusion. This ensures stable glue application quality while the board is fixed. When the moving base 403 descends, it drives the sliding column 4075 to descend as well. The spring 4076 is in its initial state, pulling up the sliding sleeve 4071. During the descent of the sliding column 4075 driven by the moving base 403, the sliding column 4075 descends, driving the spring 4076 to descend as well. After the pressing base plate 4061 contacts the board, within a certain stroke... The sliding column 4075 drives the spring 4076 to descend, which in turn drives the sliding sleeve 4071 to descend. The descending of the sliding sleeve 4071 drives the connecting frame 4072 to descend. The connecting frame 4072 drives the heating inner ring 4073 and the heating outer ring 4074 to descend. After the extrusion base plate 4061 extrudes the sheet material, the rings are embedded inside the sliding inner groove 4062 and the sliding outer groove 4063, thereby heating the inside of the extrusion base plate 4061 and curing the adhesive layer on the top of the sheet material. The enveloping arrangement of the heating inner ring 4073 and the heating outer ring 4074 provides protection for the area surrounding the descending seat 405. The area is subjected to encapsulating extrusion, thereby concentrating heating and curing at the stress point, which facilitates the curing of the adhesive layer from the stress point. At the same time, as the sliding column 4075 continues to descend, the descent of the sliding column 4075 drives the spring 4076 to descend, the descent of the spring 4076 drives the sliding sleeve 4071 to descend, and the descent of the sliding sleeve 4071 drives the connecting frame 4072 to descend. Under the elastic force of the spring 4076, the sliding sleeve 4071 is pushed to continue to descend and additional elastic force is applied, which facilitates the auxiliary downward pressure on the top of the extrusion base plate 4061 to cure the adhesive between the plate layers.

[0024] Third embodiment, please refer to Figures 1-6 Based on the second embodiment, the present invention provides a technical solution: the glue-applying rod 3 includes a rotating seat 301, a drive motor 302 is fixedly connected to the side of the rotating seat 301, a rotating frame 303 is fixedly connected to the drive shaft of the drive motor 302, a glue-applying roller 304 is slidably connected to the side of the rotating frame 303, a telescopic rod 305 is sleeved and rotatably connected to the side of the glue-applying roller 304, a feed connector 306 is rotatably connected to the side of the telescopic rod 305, the bottom of the rotating seat 301 is fixedly connected to the top of the fixed base 1 through a bracket, and the bottom of the glue-applying roller 304 is in contact with the top of the glue-applying roller 304.

[0025] The glue-applying roller 304 includes a sliding base 3041, a sliding strip 3042 fixedly connected to the side of the sliding base 3041, a glue-applying motor 3043 fixedly connected to the inner side of the sliding base 3041, a spring rod 3044 fixedly connected to the top of the sliding base 3041, a glue-applying cylinder 3045 rotatably connected to the side of the sliding base 3041, a side of the glue-applying cylinder 3045 fixedly connected to the drive shaft of the glue-applying motor 3043, and a glue outlet groove provided on the side of the glue-applying cylinder 3045. 3046, the end of the glue-applying cylinder 3045 away from the sliding base 3041 is connected to the feed pipe 3047, the feed pipe 3047 passes through the movable end of the telescopic rod 305 and is connected to the side of the telescopic rod 305, the side of the rotating seat 301 is provided with a sliding groove that matches the sliding bar 3042, the sliding base 3041 is set on the side of the rotating seat 301 and is slidably connected to the side of the rotating seat 301, and the side of the spring rod 3044 is fixedly connected to the side of the rotating seat 301 through a bracket.

[0026] The glue is introduced into the telescopic rod 305 through the feed connector 306. The glue then enters the feed pipe 3047 through the telescopic rod 305 and flows along the inner wall of the glue outlet 3046 through the glue applicator 3045. The glue is extruded through the glue outlet 3046. The drive motor 302 is started, and its drive shaft rotates the rotating frame 303. The rotation of the rotating frame 303 moves the sliding base 3041, which slides along the side of the rotating frame 303. Guided by the sliding strip 3042, the sliding base 3041 moves, causing the spring rod 3044 to move. After the board is fixed, the rotating frame 303 moves the sliding base 3041 to the top of the board. Then, the glue applicator motor 3043 is started, rotating the glue applicator 3045. The glue applicator 3045 rotates and moves along the top of the board, thus… The glue-applying motor 3043 drives the glue-applying cylinder 3045 to apply glue to the top of the board. The glue-applying motor 3043 also drives the glue-applying cylinder 3045 in the opposite direction to the movement of the rotating frame 303 and the sliding base 3041, thus applying glue to the top of the board. During the movement of the rotating frame 303 and the sliding base 3041, the bottom of the glue-applying cylinder 3045 contacts the top of the board. The pressure from the board causes the glue-applying cylinder 3045 to move along the side of the rotating frame 303. The glue-applying cylinder 3045 then drives the sliding base 3041 to slide along the side of the rotating frame 303. The movement of the sliding base 3041 causes the spring rod 3044 to move, and the elastic force of the spring rod 3044 causes the sliding base 3041 to return to its original position. This allows the glue-applying cylinder 3045 to press firmly on the top of the board, ensuring the glue is evenly applied and improving the adhesion quality between the boards.

[0027] For the fourth embodiment, please refer to [link / reference]. Figures 1-8 Based on the third embodiment, the present invention provides a technical solution: the conveying device 2 includes a fixed side plate 201, a movable roller 202 is rotatably connected to the inner side of the fixed side plate 201, a support plate 203 is fixedly connected to the inner side of the fixed side plate 201 located on one side of the movable roller 202, a limit roller 204 is fixedly connected to the inner side of the fixed side plate 201 located on one side of the movable roller 202, the bottom of the fixed side plate 201 is fixedly connected to the top of the fixed base 1, and the extrusion base plate 4061 is disposed above the support plate 203.

[0028] The limiting roller 204 includes an auxiliary roller 2041, a limiting plate 2042 is fixedly connected to the side of the auxiliary roller 2041, and the side of the auxiliary roller 2041 is rotatably connected to the inner wall side of the fixed side plate 201.

[0029] The sheet material enters the top of the support plate 203 via an external conveying device. When the extrusion base plate 4061 presses down, the pressure of the extrusion base plate 4061 is applied to the top of the sheet material. The downward pressure is transmitted through the sheet material to the top of the moving roller 202. The sheet material enters the top of the moving roller 202 via an external conveying device. The support plate 203 is designed to bear the downward pressure on the sheet material and avoid deformation caused by hard contact between the top of the moving roller 202 and the bottom of the sheet material. When the sheet material moves into the top of the moving roller 202, the auxiliary roller 2041 is activated. The rotation of the auxiliary roller 2041 drives the limiting plate 2042 to rotate. The rotating limiting plates 2042 on both sides limit the sides of the sheet material, thereby facilitating the fixing of the sheet material's position. The sheet material is stably fixed on the top of the moving roller 202 and the sides of the limiting plate 2042, thus facilitating the pressing of the extrusion base plate 4061 and the extrusion of the sheet material.
