Description

Technical Field

[0001] This utility model relates to the field of foam cutting and processing technology, and in particular to a cutting device for PMI foam production with waste collection function. Background Technology

[0002] PMI foam is a high-performance, novel polymeric foam material, officially known as polymethacrylamide foam. Due to its superior performance, PMI foam has become an important material in many high-end fields. For example, PIM foam boards, with their excellent properties, are now essential materials in aerospace, transportation, and construction. During the production and processing of PMI foam, it often requires cutting, which necessitates the use of foam production cutting equipment, as shown below.

[0003] A search revealed a patent with authorization announcement number CN210210632U, which discloses a cutting device for foam production. The device includes an operating table and an exhaust fan. The exhaust fan is bolted to a set of support legs. A cutting machine is positioned in the center of the operating table. A fixing plate is bolted to the upper part of the operating table. A glass cover is positioned above the cutting blade of the cutting machine. One end of the glass cover has an arc-shaped notch. The fixing plate movably passes through the end of the glass cover away from the arc-shaped notch. A gas collection hood is located outside the cutting machine below the operating table. A connecting pipe is connected to the lower part of the gas collection hood, and this connecting pipe is connected to the air inlet of the exhaust fan. A non-woven fabric bag is connected to the air outlet of the exhaust fan. This device collects the dust generated during foam cutting, preventing dust from escaping and protecting the health of workers. Furthermore, the collected dust can be recycled, saving raw materials.

[0004] However, the aforementioned foam production cutting device still has the following areas for improvement. For example, while the dust can be drawn into a non-woven bag for collection during foam cutting, the dust enters the fan before reaching the bag. Once inside the fan, the dust settles or suspends with the airflow, causing a series of problems, including mechanical wear, reduced efficiency, and safety hazards. Specifically, dust particles have a certain hardness and abrasiveness; when they pass at high speed through fan blades, bearings, and other components, they rub against these surfaces, causing wear. Furthermore, dust accumulation inside the fan gradually clogs the blades and ventilation ducts, narrowing the airflow and hindering air circulation. Uneven dust deposition can lead to an imbalance in the mass distribution of the blades or rotor, causing vibration during fan operation and potentially leading to mechanical failure. These problems directly affect the performance and lifespan of the fan. Therefore, a PMI foam production cutting device with waste collection capabilities is urgently needed to solve these technical issues. Utility Model Content

[0005] This utility model discloses a cutting device for PMI foam production with waste collection function. It features a dust-collecting cutting mechanism, allowing foam boards to be placed on two vacuum suction cups and positioned between them for cutting. The vacuum suction cups are then activated to hold the foam board in place. Two cylinders and a cutting motor are then activated; the cylinders extend, lowering a lifting hood until it contacts the top of the processing table. The cutting motor rotates the cutting blade, thus cutting the foam board. During this process, the lifting hood can collect the waste generated during the cutting of the foam board. A large amount of dust is collected and intercepted to a certain extent. At the same time, the exhaust fan can be activated. The exhaust fan, in conjunction with the hose, dust collection box, and duct, generates negative pressure suction at the two dust collection hoods, thereby effectively drawing the large amount of dust generated during cutting into the dust collection box. After being intercepted and filtered by the filter plate, clean air is discharged from the exhaust fan's outlet. In this way, not only can foam dust be effectively collected, preventing it from polluting the nearby air environment and harming nearby workers, but it can also effectively ensure that the dust will not damage the exhaust fan, extending its service life. In summary, the problems in the background technology are solved.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model discloses a cutting device for PMI foam production with waste collection function, including a processing table. The bottom of the processing table is provided with multiple support legs.

Multiple support columns are fixedly connected to the top of the processing table, and a top seat is fixedly connected to the top of the multiple support columns. Two sliding grooves are opened laterally on the bottom of the top seat, and sliding blocks are slidably installed at the two sliding grooves through sliding connectors. A through movable groove is opened inside the top seat between the two sliding grooves.

[0008] A drive mechanism, which is located on top of the top seat and fixedly connected to the top of the slide;

[0009] A dust-collecting cutting mechanism includes cylinders, a lifting hood, a mounting base, a cutting motor, a dust collection box, and an exhaust fan. Two cylinders are fixedly mounted on a sliding base in a through-type configuration. The top of the lifting hood is fixedly connected to the telescopic ends of the two cylinders. The bottom of the lifting hood is open, and notches are provided on both sides of the lifting hood. The size of the notches is larger than the maximum distance between two vacuum suction cups. The mounting base is L-shaped and fixedly mounted on the top of the lifting hood. The cutting motor is fixedly mounted on the mounting base, and a cutting blade is provided at the output end of the cutting motor. The dust collection box is fixedly mounted on the top of the lifting hood, and a filter plate is movably mounted inside the dust collection box. Dust guides are connected to both sides of the dust collection box, and the bottom ends of both dust guides penetrate the top of the lifting hood. A dust collection hood is located at the bottom of each dust guide. The exhaust fan is fixedly mounted on the top of the sliding base, and the exhaust end of the exhaust fan is connected to one side of the dust collection box via a flexible hose. The flexible hose and the dust guides are located above and below the filter plate, respectively.

[0010] Furthermore, a door is hinged to one side of the dust collection box, and the door is sealed to the dust collection box when closed.

[0011] Furthermore, multiple rollers are rotatably mounted on the bottom of the lifting cover, and the bottom height of the rollers is lower than the bottom height of the lifting cover.

[0012] Furthermore, the bottom height of the cutting blade is consistent with the bottom height of the lifting cover.

[0013] Furthermore, the bottom height of the dust collection hood is higher than the top height of the notches on both sides of the lifting hood.

[0014] Furthermore, the driving mechanism includes a lead screw and a drive motor. The lead screw is rotatably mounted on the top of the top seat via two bearing seats. A slider is screwed to the outside of the lead screw. The bottom of the slider passes through a movable groove and is fixedly connected to the top of the slide seat. The drive motor is fixedly mounted on the top of the top seat, and the output end of the drive motor is connected to the shaft end of the lead screw.

[0015] The present invention has the following advantages over the prior art:

[0016] 1. This technical solution incorporates a dust-collecting cutting mechanism. During operation, the foam board can be placed on two vacuum suction cups and positioned so that the cutting point is between the two suction cups. The vacuum suction cups are then activated to hold the foam board in place. The foam board can then be cut using the dust-collecting cutting mechanism, which effectively extracts the large amount of dust generated during cutting into the dust collection box within the mechanism. After being filtered by a filter screen, the dust is discharged as clean air from the exhaust fan. This not only effectively collects the foam dust, preventing it from polluting the surrounding air environment and harming nearby workers, but also ensures that the dust will not damage the exhaust fan, extending its service life and greatly improving the practicality of the device.

[0017] 2. This technical solution, by incorporating a drive mechanism and vacuum suction cups, allows the foam board to be placed on two vacuum suction cups and positioned so that the cutting point is between the two suction cups during operation. The vacuum suction cups are then activated to hold the foam board in place, enabling cutting. The drive mechanism moves the sliding block, which in turn moves the cutting blade, cutting the foam board along the designated path. This eliminates the need for manual adjustment of the foam board's position, saving time and effort, increasing efficiency, and further enhancing the device's practicality.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] In the description of this utility model, it should be understood that the terms "surface", "side", "gap", "peripheral", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Specific Implementation Example 1:

[0028] Reference Figures 1-4 A cutting device for PMI foam production with waste collection function includes a processing table 1. The bottom of the processing table 1 is provided with multiple support legs. Two vacuum suction cups 2 are fixedly installed on the top of the processing table 1. There is a certain distance between the two vacuum suction cups 2. Multiple support columns 3 are fixedly connected to the top of the processing table 1. Top seats 4 are fixedly connected to the top of the multiple support columns 3. Two sliding grooves 5 are opened laterally on the bottom of the top seat 4. Sliding seats 6 are slidably installed at the two sliding grooves 5 through sliding connectors. A through movable groove 7 is opened in the interior of the top seat 4 between the two sliding grooves 5.

[0029] The drive mechanism 8 is located on top of the top seat 4 and is fixedly connected to the top of the slide 6. The dust-collecting cutting mechanism 9 includes a cylinder 901, a lifting cover 902, a mounting base 903, a cutting motor 904, a dust collection box 905, and an exhaust fan 906. Two cylinders 901 are provided, both of which are fixedly installed through the slide 6. The top of the lifting cover 902 is fixedly connected to the telescopic ends of the two cylinders 901. The bottom of the lifting cover 902 has an open design, and notches 907 are provided on both the left and right sides of the lifting cover 902. The size of the notches 907 is larger than the maximum distance between the two vacuum suction cups 2. The mounting base 903 is L-shaped and is fixedly installed... The cutting motor 904 is fixedly installed on the mounting base 903 at the top of the lifting cover 902. The output end of the cutting motor 904 is equipped with a cutting blade 908. The dust collection box 905 is fixedly installed on the top of the lifting cover 902. The filter screen plate 909 is installed inside the dust collection box 905. The left and right sides of the dust collection box 905 are connected to the ducts 910. The bottom ends of the two ducts 910 penetrate the top of the lifting cover 902. The bottom of the ducts 910 is equipped with a dust collection cover 911. The exhaust fan 906 is fixedly installed on the top of the slide 6. The exhaust end of the exhaust fan 906 is connected to one side of the dust collection box 905 through the hose 912. The hose 912 and the duct 910 are located above and below the filter screen plate 909, respectively.

[0030] A door 913 is hinged to one side of the dust collection box 905, and the door 913 is sealed to the dust collection box 905 when closed; multiple rollers 914 are rotatably mounted on the bottom of the lifting hood 902, and the bottom height of the rollers 914 is lower than the bottom height of the lifting hood 902; the bottom height of the cutting blade 908 is the same as the bottom height of the lifting hood 902; the bottom height of the dust collection hood 911 is higher than the top height of the notches 907 on both sides of the lifting hood 902.

[0031] In the specific implementation process, during operation, the foam board can be placed on two vacuum suction cups 2 and its position adjusted so that the cutting position is between the two vacuum suction cups 2. Then, the vacuum suction cups 2 can be activated to adsorb and fix the foam board. Then, the two cylinders 901 and the cutting motor 904 can be activated. The extension of cylinder 901 can drive the lifting cover 902 to move down until the lifting cover 902 moves down to contact the top of the processing table 1. The operation of the cutting motor 904 can drive the cutting blade 908 to rotate, thereby cutting the foam board. During this process, the lifting cover 902 can collect a certain amount of dust generated during the cutting of the foam board. The system gathers and intercepts dust while simultaneously activating the exhaust fan 906. The exhaust fan 906, in conjunction with the hose 912, dust collection box 905, and duct 910, generates negative pressure suction at the two dust collection hoods 911. This effectively draws the large amount of dust generated during cutting into the dust collection box 905, where it is filtered and intercepted by the filter plate 909 before being discharged as clean air from the exhaust fan 906. This not only effectively collects foam dust, preventing pollution of the surrounding air environment and harm to nearby workers, but also ensures that the dust does not damage the exhaust fan 906, extending its service life.

[0032] The dust inside the dust collection box 905 can be cleaned by opening the door 913, and the filter plate 909 can be disassembled and cleaned. The door 913 is sealed to the dust collection box 905 when closed to ensure the airtightness of the dust collection box 905 and to ensure that negative pressure suction can be generated at the dust collection hood 911.

[0033] Among them, the roller 914 can prevent the bottom of the lifting cover 902 from directly contacting the processing table 1, so that when the lifting cover 902 moves in the future, the sliding friction is changed to rolling friction, reducing the friction force, facilitating the movement of the lifting cover 902, and also reducing the wear on the lifting cover 902.

[0034] The bottom height of the cutting blade 908 is the same as the bottom height of the lifting cover 902 so that it can cut the foam board placed on the two vacuum suction cups 2 more effectively.

[0035] The bottom height of the dust collection hood 911 is higher than the top height of the notches 907 on both sides of the lifting hood 902 so that the dust collection hood 911 can better suck up dust. Specific Implementation Example 2:

[0037] Reference Figure 1 and Figure 5In a preferred embodiment, the drive mechanism 8 includes a lead screw 801 and a drive motor 802. The lead screw 801 is rotatably mounted on the top of the top seat 4 via two bearing seats 803. A slider 804 is screwed to the outside of the lead screw 801. The bottom of the slider 804 passes through the movable groove 7 and is fixedly connected to the top of the slide seat 6. The drive motor 802 is fixedly mounted on the top of the top seat 4, and the output end of the drive motor 802 is connected to the shaft end of the lead screw 801.

[0038] In the specific implementation process, during operation, the foam board can be placed on two vacuum suction cups 2 and its position adjusted so that the cutting position is between the two vacuum suction cups 2. Then, the vacuum suction cups 2 can be activated to adsorb and fix the foam board, and then the foam board can be cut and processed. Furthermore, by activating the drive motor 802, the lead screw 801 is rotated, which, in conjunction with the slide groove 5 and the slider 804, moves the slide block 6, thereby moving the cutting blade 908 to move along the cutting trajectory to cut and process the foam board. There is no need for manual adjustment of the position of the foam board, which saves time and effort and is highly efficient.

[0039] Working principle: During operation, the foam board can be placed on two vacuum suction cups 2 and its position adjusted so that the cutting position is between the two vacuum suction cups 2. Then, the vacuum suction cups 2 can be activated to adsorb and fix the foam board. Then, the two cylinders 901 and the cutting motor 904 can be activated. The extension of the cylinders 901 can drive the lifting cover 902 to move down until the lifting cover 902 moves down to contact the top of the processing table 1. The operation of the cutting motor 904 can drive the cutting blade 908 to rotate, thereby cutting the foam board. Furthermore, by activating the drive motor 802, the lead screw 801 can be rotated, which, in conjunction with the slide groove 5 and the slider 804, drives the slide 6 to move, thereby driving the cutting blade 908 to move and cut the foam board along the cutting trajectory. There is no need for manual adjustment of the position of the foam board, which saves time and effort and has high efficiency.

[0040] During this process, the lifting hood 902 can collect and intercept a large amount of dust generated during the cutting of foam boards to a certain extent. At the same time, the exhaust fan 906 can be activated. The exhaust fan 906, in conjunction with the hose 912, dust collection box 905, and duct 910, generates negative pressure suction at the two dust collection hoods 911, thereby effectively drawing the large amount of dust generated during cutting into the dust collection box 905. After being intercepted and filtered by the filter plate 909, clean air is discharged from the exhaust fan 906. In this way, not only can the foam dust be effectively collected, preventing it from polluting the nearby air environment and harming nearby workers, but it can also effectively ensure that the dust will not damage the exhaust fan 906, extending the service life of the exhaust fan 906.

[0041] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
