Description

Technical Field

[0001] This invention relates to the field of nano-calcium board slitting technology, specifically to a nano-calcium board extrusion slitting equipment and method. Background Technology

[0002] Nano-calcium board is a composite board made by using nano-scale calcium-based materials as the main inorganic filler, combined with organic polymer matrix and functional additives, and prepared through processes such as mixing, extrusion, and molding. This type of board combines the rigidity and flame retardancy of inorganic materials with the toughness and processability of organic materials. It also has the unique high specific surface area effect and interface enhancement effect of nanomaterials. Therefore, it is widely used in fields such as building decoration, interior partitions, advertising displays, packaging cushioning, and functional substrates. In the production process of nano-calcium boards, extrusion molding is a key step in the preparation of the preform. After the preform is extruded, it needs to be slit according to the specifications of the end product. The existing nano-calcium board extrusion and slitting equipment has a complicated process for adjusting the spacing between adjacent cutters, which makes the operation time-consuming and labor-intensive for the staff. In addition, existing slitting equipment is not easy to quickly absorb the dust generated during cutting. If there is a lot of dust, it can easily cause safety hazards and also affect the health of workers. Therefore, a nano-calcium board extrusion and slitting device is needed to solve the above problems. Summary of the Invention

[0003] The purpose of this invention is to provide a nano-calcium board extrusion and slitting device and method to solve the problems mentioned in the background art, such as the inconvenience of adjusting the spacing between adjacent cutters and the inability to quickly remove dust.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A nano-calcium board extrusion and slitting device includes a support frame and rollers distributed on the support frame. An induction extrusion mechanism is installed at the feed end of the support frame, and the induction extrusion mechanism includes a connecting frame that movably passes through the support frame. Rollers are also installed on the connecting frame. A mounting frame is fixedly connected to the support frame, and a motor is installed on one side of the mounting frame. A support shaft coaxial with the output end of the motor is fixedly connected to the motor. A cutter is installed on the support shaft via a spacing adjustment mechanism. The spacing adjustment mechanism includes a mounting seat movably sleeved on the outside of the support shaft, and the cutter is fixedly installed in the middle of the mounting seat. A dust adsorption mechanism is also installed on the support frame, and the dust adsorption mechanism includes a front support frame plate fixedly installed on the support frame, the front support frame plate being positioned between the feed end of the support frame and the mounting frame plate.

[0005] Preferably, the inductive extrusion mechanism further includes a guide shaft disposed at the lower end of the connecting frame, and the upper end of the guide shaft is movably disposed through the support frame, and a spring is movably sleeved on the outside of the guide shaft between the lower end of the connecting frame and the support frame.

[0006] Preferably, a permanent magnet sheet is provided on the lower surface of the upper end of the connecting frame, and an electromagnetic sheet is provided on the upper surface of the support frame, with the electromagnetic sheet and the permanent magnet sheet being arranged in a one-to-one correspondence. A position sensor is installed on the inner side of the support frame, and the position sensor is located below the connecting frame.

[0007] Preferably, the support shaft is prismatic, and the mounting base has a prismatic through hole that matches the support shaft, so that when the support shaft rotates, the mounting base can be driven to rotate synchronously, and the mounting base can slide on the support shaft.

[0008] Preferably, the spacing adjustment mechanism further includes a mounting bracket connected to the mounting base by a bearing. The mounting frame plate is provided with a strip-shaped through groove running through both sides, and the upper end of the mounting bracket is movably connected through the strip-shaped through groove. The upper end of the mounting bracket is connected to the mounting frame plate by a sliding connection.

[0009] Preferably, a guide plate is slidably connected to the mounting frame, and a guide groove is provided on both sides of the guide plate. The middle part of the mounting frame is slidably connected through the corresponding guide groove. A rear support frame is also fixedly connected to the support frame, and the rear support frame is located between the mounting frame and the discharge end of the support frame. A cylinder is installed on the rear support frame, and the guide plate is connected to the extension end of the cylinder.

[0010] Preferably, the dust adsorption mechanism further includes a liquid collection tank installed on the support frame, and a suction pipe and a negative pressure pipe are connected through the liquid collection tank. The suction pipe and the negative pressure pipe are respectively connected through the liquid collection tank below the liquid surface and above the liquid surface. The guide plate is also slidably connected to the front support frame plate, and a dust collection box is installed on the front support frame plate. The dust collection box has strip-shaped suction holes, and both ends of the dust collection box are respectively connected through the corresponding suction pipes. A centrifugal fan is installed on the support frame, and the centrifugal fan is connected through the negative pressure pipe.

[0011] Preferably, the interior of the dust collection box is designed with a ramp that is higher in the middle and lower at both ends, so that the dust collected by the dust collection box can slide down the ramp to both ends of the dust collection box.

[0012] Preferably, a roller track is provided on the inner side of the strip-shaped suction hole, and a suction frame is provided inside the strip-shaped suction hole. Both sides of the suction frame are slidably connected to the corresponding roller track through roller assemblies. Adjacent suction frames and the ends of the suction frames and the strip-shaped suction holes are connected by telescopic covers. The telescopic covers are used to block the parts of the strip-shaped suction hole where no suction frame is provided, thereby improving the suction force of the suction frame opening. The suction frames and cutters are provided one-to-one, and the suction frames are connected to the corresponding mounting brackets through connecting arms.

[0013] A method for extruding and slitting nano-calcium board using an extrusion and slitting device, the method comprising: Step 1: According to the requirements for cutting the nano-calcium board, start the cylinder. When the cylinder is started, it can drive the guide plate to move. When the guide plate moves, the distance between adjacent mounting seats can be changed synchronously through the guide groove and the mounting bracket. Thus, the position of the cutter can be adjusted according to the cutting requirements. At the same time, the position of the dust collection frame is adjusted synchronously through the connecting arm. Step 2: Push the nano-calcium plate into the support frame from the feeding end. When the nano-calcium plate enters the bottom of the connecting frame, the position sensor detects the nano-calcium plate, and the control equipment energizes the electromagnetic plate according to the signal fed back by the position sensor. Step 3: After the electromagnetic sheet is energized, it will attract the corresponding permanent magnet sheet, which will drive the connecting frame to move downward. This will cause the rollers on the connecting frame and the rollers on the support frame to squeeze the nano-calcium plate, preventing it from shaking in the vertical direction during the cutting process. During the above process, the spring is stretched. Step 4: While the nano-calcium board is being conveyed by the roller, the motor is started. The motor drives the support shaft to rotate, which in turn enables the cutter to rotate at high speed through the mounting base. As the cutter rotates at high speed, the nano-calcium board gradually approaches the cutter and is thus cut. Step 5: While the cutter is cutting the nano-calcium board, the centrifugal fan starts due to the rotation of the support shaft, which can then draw away the gas above the liquid surface in the sealed collection tank through the negative pressure pipe, thereby creating negative pressure in the collection tank. After the negative pressure is transmitted, it creates negative pressure inside the suction pipe, which in turn creates suction at the opening of the suction frame. This suction absorbs the dust generated when the cutter cuts the nano-calcium board. The absorbed dust enters the dust collection box and then flows through the suction pipe into the liquid collection box, where it is absorbed by the liquid. This prevents dust from flying around and avoids safety and health problems caused by dust.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the nano-calcium board extrusion and slitting equipment can quickly adjust the position of the cutter, thereby reducing the complexity of operation for workers and helping to improve slitting efficiency. In addition, it can quickly absorb the dust generated during slitting at specific points, which not only avoids dust explosions but also prevents workers from inhaling the dust and affecting their health. 1. By driving the guide plate with a cylinder, the guide groove on it can move relative to the mounting frame, allowing the mounting frame to slide within the guide groove. This facilitates quick adjustment of the spacing between adjacent mounting frames, enabling synchronous adjustment of the cutter position mounted on the mounting frame. Since the cutter position can be adjusted simply by controlling the extension and retraction of the cylinder end, it is easy for operators to operate quickly, reducing the difficulty of adjustment and increasing the speed of adjustment, thus helping to improve slitting efficiency. 2. When adjusting the position of the mounting bracket, the position of the dust collection frame can be adjusted synchronously via the connecting arm, ensuring that the position of the dust collection frame always corresponds to the cutter. This allows for targeted absorption of dust generated during the cutting of nano-calcium boards, and the dust can be drawn through the suction pipe into a liquid collection tank, where it is absorbed by the liquid, preventing dust from flying around. This not only avoids the safety hazards that can easily arise from excessive dust, but also prevents workers from inhaling dust, thus protecting their health. Attached Figure Description

[0017] 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.

[0018] Please see Figures 1-11 The present invention provides the following technical solution: Example 1: To solve the problem that previous nano-calcium board extrusion and slitting equipment could not quickly adjust the spacing between cutters 21, the following technical solution is provided: Specifically, a nano-calcium board extrusion and slitting equipment includes a support frame 1 and rollers 3 distributed on the support frame 1. An induction extrusion mechanism is installed at the feeding end of the support frame 1, and the induction extrusion mechanism includes a connecting frame 2 that movably passes through the support frame 1. Rollers 3 are also installed on the connecting frame 2. A mounting frame plate 5 is fixedly connected to the support frame 1, and a motor 11 is installed on one side of the mounting frame plate 5. A support shaft 18 coaxial with the output end of the motor 11 is fixedly connected, and cutters 21 are installed on the support shaft 18 through a spacing adjustment mechanism. The spacing adjustment mechanism includes a mounting seat 20 that is movably sleeved on the outside of the support shaft 18, and the cutter 21 is fixedly installed in the middle of the mounting seat 20.

[0019] In a preferred embodiment of the invention, the inductive compression mechanism further includes a guide shaft 12 disposed at the lower end of the connecting frame 2, and the upper end of the guide shaft 12 is movably disposed through the support frame 1. A spring 8 is movably sleeved on the outside of the guide shaft 12 between the lower end of the connecting frame 2 and the support frame 1.

[0020] In the above technical solution, by setting the guide shaft 12, it is possible not only to ensure that the connecting frame 2 can only move in the vertical direction, but also to limit the spring 8, so that the spring 8 can only be compressed and stretched in the vertical direction.

[0021] In a preferred embodiment of the invention, a permanent magnet sheet is provided on the lower surface of the upper end of the connecting frame 2, an electromagnetic sheet 7 is provided on the upper surface of the support frame 1, and the electromagnetic sheet 7 is provided in a one-to-one correspondence with the permanent magnet sheet. A position sensor 13 is installed on the inner side of the support frame 1, and the position sensor 13 is located below the connecting frame 2.

[0022] In the above technical solution, after the nano-calcium plate is squeezed under the connecting frame 2, the position sensor 13 can sense the nano-calcium plate and transmit the signal to the control device. The control device energizes the electromagnetic plate 7 so that the electromagnetic plate 7 can attract the permanent magnet plate, thereby squeezing the nano-calcium plate and preventing the nano-calcium plate from shaking in the vertical direction during the cutting process.

[0023] In a preferred embodiment of the invention, the support shaft 18 is prismatic, and the mounting base 20 has a prismatic through hole that matches the support shaft 18, so that when the support shaft 18 rotates, the mounting base 20 can be driven to rotate synchronously, and the mounting base 20 can slide on the support shaft 18.

[0024] In the above technical solution, the support shaft 18 and the mounting base 20 are connected by a matching prism structure, which not only allows the mounting base 20 to rotate synchronously when the support shaft 18 rotates, but also allows the mounting base 20 to slide on the support shaft 18, thereby providing the possibility of quickly adjusting the position of the cutter 21.

[0025] In a preferred embodiment of the invention, the spacing adjustment mechanism further includes a mounting bracket 17 that is bearing-connected to the mounting base 20. The mounting frame plate 5 is provided with a strip-shaped through groove 26 that runs through both sides of it. The upper end of the mounting bracket 17 is movably connected through the strip-shaped through groove 26, and the upper end of the mounting bracket 17 is connected to the mounting frame plate 5 by a sliding connection.

[0026] In the above technical solution, by sliding the mounting frame 5 to the upper end of the mounting bracket 17, the stability of the movement of the mounting bracket 17 can be guaranteed, which means that the stability of the cutter 21 when changing position can be guaranteed.

[0027] In a preferred embodiment of the invention, a guide plate 15 is slidably connected to the mounting frame 5, and a guide groove 16 is provided on the guide plate 15 through both sides. The middle part of the mounting frame 17 is slidably connected through the corresponding guide groove 16. A rear support frame 6 is also fixedly connected to the support frame 1, and the rear support frame 6 is located between the mounting frame 5 and the discharge end of the support frame 1. A cylinder 14 is mounted on the rear support frame 6, and the guide plate 15 is connected to the telescopic end of the cylinder 14.

[0028] In the above technical solution, the guide plate 15 is moved by the cylinder 14, so that the middle part of the mounting bracket 17 can slide in the guide groove 16 on the guide plate 15, thereby quickly adjusting the distance between adjacent mounting brackets 17, that is, quickly adjusting the distance between adjacent cutters 21. Since only the cylinder 14 needs to be controlled, the labor intensity and operation steps of the workers can be greatly reduced, and the work efficiency can be improved, which helps to improve the efficiency of slitting.

[0029] according to Figures 1-7 When in use, according to the cutting requirements, control the cylinder 14 to push or pull the guide plate 15. When the guide plate 15 moves, the mounting bracket 17 will slide relative to the guide groove 16 on the guide plate 15, thereby achieving the purpose of quickly adjusting the distance between adjacent mounting brackets 17. Since both the cutter 21 and the mounting bracket 17 are mounted on the mounting base 20, the distance between adjacent cutters 21 can be adjusted synchronously. Subsequently, the motor 11 is started. When the motor 11 is started, it will drive the support shaft 18 to rotate at high speed. When the support shaft 18 rotates at high speed, it will not only make the cutter 21 rotate at high speed, but also make the blades inside the centrifugal fan 10 rotate at high speed. Then the nano-calcium board is pushed to the feed end of the support frame 1, so that the nano-calcium board is gradually conveyed to the bottom of the connecting frame 2 through the roller 3. When the nano-calcium board moves to the bottom of the connecting frame 2, it will be detected by the position sensor 13. The position sensor 13 transmits a signal to the control device, which then energizes the electromagnetic plate 7, causing the electromagnetic plate 7 to attract the permanent magnet plate, thereby causing the connecting frame 2 to move downward. During the process, the spring 8 is stretched, and the rollers 3 on the support frame 1 and the connecting frame 2 squeeze the nano-calcium plate to prevent it from shaking in the vertical direction. Subsequently, as the nano-calcium plate gradually approaches the high-speed rotating cutter 21, the nano-calcium plate is cut.

[0030] Example 2: To solve the problem in Example 1 that the dust generated during slitting cannot be quickly absorbed at a fixed point, the following technical solution is provided: Specifically, a dust adsorption mechanism is also installed on the support frame 1, and the dust adsorption mechanism includes a front support frame plate 4 fixedly installed on the support frame 1, with the front support frame plate 4 located between the feed end of the support frame 1 and the mounting frame plate 5.

[0031] In a preferred embodiment of the invention, the dust adsorption mechanism further includes a liquid collection tank 9 mounted on the support frame 1, and a suction pipe 25 and a negative pressure pipe 27 are connected through the liquid collection tank 9. The suction pipe 25 and the negative pressure pipe 27 are respectively connected through the liquid below the liquid surface and above the liquid surface in the liquid collection tank 9. The guide plate 15 is also slidably connected to the front support frame plate 4, and a dust collection box 19 is mounted on the front support frame plate 4. The dust collection box 19 has a strip-shaped suction hole 28, and both ends of the dust collection box 19 are respectively connected through the corresponding suction pipe 25. A centrifugal fan 10 is mounted on the support frame 1, and the centrifugal fan 10 is connected through the negative pressure pipe 27.

[0032] In the above technical solution, the air above the liquid surface in the liquid collection tank 9 is drawn out by the centrifugal fan 10 and the negative pressure pipe 27 to form a negative pressure, which in turn can form a negative pressure in the space formed by the suction pipe 25 and the dust collection box 19, so that the opening of the suction frame 23 can generate suction.

[0033] In a preferred embodiment of the invention, the interior of the dust collection box 19 is provided with a ramp that is higher in the middle and lower at both ends, so that the dust collected by the dust collection box 19 can slide down the ramp to both ends of the dust collection box 19.

[0034] In the above technical solution, dust can easily enter the dust collection box 19 and slide down the ramp to the part where the dust collection box 19 meets the suction pipe 25, so that the dust can enter the liquid collection box 9 below the liquid surface through the suction pipe 25, which helps to adsorb the dust.

[0035] In a preferred embodiment of the invention, a roller track 30 is provided on the inner side of the strip-shaped suction hole 28, and a suction frame 23 is provided inside the strip-shaped suction hole 28. Both sides of the suction frame 23 are slidably connected to the corresponding roller track 30 through roller assemblies 29. Adjacent suction frames 23 and the ends of suction frames 23 and strip-shaped suction holes 28 are connected by telescopic covers 24. The telescopic covers 24 are used to block the parts of the strip-shaped suction hole 28 where suction frames 23 are not provided, thereby improving the suction force of the opening of the suction frame 23. The suction frames 23 and the cutter 21 are provided one-to-one, and the suction frames 23 are connected to the corresponding mounting bracket 17 through connecting arms 22.

[0036] In the above technical solution, the roller track 30 and roller assembly 29 enable the dust collection frame 23 to slide stably on the strip-shaped dust collection hole 28, and the telescopic cover 24 ensures that the suction force at the opening of the dust collection frame 23 is large enough, which helps to quickly absorb dust at a fixed point.

[0037] according to Figures 8-11 When in use, because the blades in the centrifugal fan 10 rotate at high speed, the negative pressure pipe 27 can draw in the gas above the liquid surface in the liquid collection tank 9, so that a negative pressure is formed in the sealed liquid collection tank 9. When negative pressure is generated in the collection tank 9, because the collection tank 9 is connected to the suction pipe 25, negative pressure will be generated in the space formed by the suction pipe 25 and the collection tank 19. When negative pressure is generated inside the dust collection box 19, the strip-shaped suction hole 28 will generate suction, so that the part of it covered by the telescopic cover 24 will fit more tightly with the telescopic cover 24 due to the suction. The part of the strip-shaped suction hole 28 where the suction frame 23 is set will generate a large suction force, which can quickly absorb the dust generated by the cutting. In addition, since the connecting arm 22 connects the vacuum frame 23 and the mounting bracket 17, the position of the vacuum frame 23 can be adjusted synchronously when the position of the mounting bracket 17 is adjusted, thereby ensuring that the positions of the vacuum frame 23 and the cutter 21 always correspond, which helps to achieve fixed-point vacuuming. By using fixed-point vacuuming, dust can be quickly and efficiently absorbed into the liquid collection tank 9, and the dust is absorbed by the liquid in the liquid collection tank 9, thereby preventing dust from flying around. This not only avoids the safety problems that dust can easily cause, but also prevents dust from being inhaled by workers, thus helping to protect the health of workers.

[0038] A method for extruding and slitting nano-calcium board using an extrusion and slitting device, the method comprising: Step 1: According to the requirements for cutting the nano-calcium board, start the cylinder 14. When the cylinder 14 is started, it can drive the guide plate 15 to move. When the guide plate 15 moves, the distance between adjacent mounting seats 20 can be changed synchronously through the guide groove 16 and the mounting bracket 17. Thus, the position of the cutter 21 can be adjusted according to the cutting requirements. At the same time, the position of the dust collection frame 23 is adjusted synchronously through the connecting arm 22. Step 2: Push the nano-calcium plate into the feed end of the support frame 1. When the nano-calcium plate enters the lower part of the connecting frame 2, the position sensor 13 senses the nano-calcium plate and the control device energizes the electromagnetic plate 7 according to the signal fed back by the position sensor 13. Step 3: After the electromagnetic plate 7 is energized, it will attract the corresponding permanent magnet plate, thereby driving the connecting frame 2 to move downward, so that the roller 3 on the connecting frame 2 and the roller 3 on the support frame 1 will squeeze the nano-calcium plate to prevent it from shaking in the vertical direction during the cutting process. During the above process, the spring 8 is stretched. Step 4: While the nano-calcium board is being conveyed by the roller 3, the motor 11 is started. The motor 11 drives the support shaft 18 to rotate, which in turn enables the cutter 21 to rotate at high speed through the mounting base 20. When the cutter 21 rotates at high speed, the nano-calcium board gradually approaches the cutter 21 and is thus cut. Step 5: While the cutter 21 is cutting the nano-calcium plate, the centrifugal fan 10 is started due to the rotation of the support shaft 18, which can then draw away the gas above the liquid surface in the sealed collection tank 9 through the negative pressure pipe 27, thereby creating a negative pressure in the collection tank 9. After the negative pressure is transmitted, it creates a negative pressure inside the suction pipe 25, which in turn creates suction at the opening of the suction frame 23. This suction absorbs the dust generated when the cutter 21 cuts the nano-calcium board. The absorbed dust enters the dust collection box 19 and then flows along the suction pipe 25 into the liquid collection box 9, where it is absorbed by the liquid. This prevents the dust from flying around and avoids safety issues and health problems for the staff caused by the dust.

The nano-calcium plate extrusion and slitting equipment according to claim 7, characterized in that: The inner side of the strip-shaped suction hole (28) is provided with a roller track (30), and a suction frame (23) is provided inside the strip-shaped suction hole (28). Both sides of the suction frame (23) are slidably connected to the corresponding roller track (30) through roller assembly (29). Adjacent suction frames (23) and the ends of suction frames (23) and strip-shaped suction holes (28) are connected by telescopic covers (24). The telescopic covers (24) are used to block the parts of the strip-shaped suction hole (28) where no suction frame (23) is provided, thereby improving the suction force of the opening of the suction frame (23). The suction frame (23) is provided in a one-to-one correspondence with the cutter (21), and the suction frame (23) is connected to the corresponding mounting bracket (17) through connecting arm (22).

10. A method for extruding and slitting a nano-calcium board extrusion and slitting device, which is applied to the nano-calcium board extrusion and slitting device as described in any one of claims 1-9, characterized in that: The method includes: Step 1: According to the requirements of cutting the nano-calcium board, start the cylinder (14). When the cylinder (14) is started, it can drive the guide plate (15) to move. When the guide plate (15) moves, the distance between adjacent mounting seats (20) can be changed synchronously through the guide groove (16) and the mounting bracket (17). Thus, the position of the cutter (21) can be adjusted according to the cutting requirements. At the same time, the position of the dust collection frame (23) is adjusted synchronously through the connecting arm (22). Step 2: Push the nano-calcium plate into the feed end of the support frame (1). When the nano-calcium plate enters the bottom of the connecting frame (2), the position sensor (13) senses the nano-calcium plate, and the control device powers the electromagnetic plate (7) according to the signal fed back by the position sensor (13). Step 3: After the electromagnetic sheet (7) is energized, it will attract the electromagnetic sheet (7) and the corresponding permanent magnet sheet, thereby driving the connecting frame (2) to move downward, so that the roller (3) on the connecting frame (2) and the roller (3) on the support frame (1) will squeeze the nano-calcium plate to prevent it from shaking in the vertical direction during the cutting process. During the above process, the spring (8) is stretched. Step 4: While the nano-calcium board is being conveyed by the roller (3), the motor (11) is started. The motor (11) drives the support shaft (18) to rotate, which in turn enables the cutter (21) to rotate at high speed through the mounting base (20). When the cutter (21) rotates at high speed, the nano-calcium board gradually approaches the cutter (21) and is thus cut. Step 5: While the cutter (21) cuts the nano-calcium plate, the centrifugal fan (10) is started due to the rotation of the support shaft (18), which can then draw away the gas above the liquid surface in the sealed collection tank (9) through the negative pressure pipe (27), thereby generating negative pressure in the collection tank (9); After the negative pressure is transmitted, it causes a negative pressure to be generated in the suction pipe (25), thereby generating suction at the opening of the suction frame (23), which in turn absorbs the dust generated when the cutter (21) cuts the nano-calcium board. After the absorbed dust enters the dust collection box (19), it enters the liquid collection box (9) along the suction pipe (25) and is then adsorbed by the liquid in the liquid collection box (9), thereby preventing dust from flying and preventing dust from causing safety problems and health problems of workers.
