An automated cutting device and a cutting process for SMC molding compound production

Abstract

The present invention relates to the technical field of SMC molding compound production, and specifically, to an automatic cutting device and a cutting process for SMC molding compound production. In this automatic cutting device and the cutting process for SMC molding compound production, a side control mechanism on the side end of the tool body can adhere and adsorb the dust generated during the cutting process while the tool body is moving for cutting. Notably, timely adsorption during the cutting process can significantly improve the dust adsorption effect. This is because during the cutting process, the temperature at the cutting seam of the molding compound body will increase due to cutting, and the dust generated at this time is more easily adhered and adsorbed. At the same time, this adsorption method will not cause additional damage to the surface of the sheet-shaped molding compound body.

Description

Technical Field

[0001] The present invention relates to the technical field of SMC molding compound production, and more specifically, to an automated cutting device and a cutting process for SMC molding compound production. Background Art

[0002] In the automotive field, SMC molding compounds are mainly used in the manufacture of components such as automotive body panels and engine hoods. Since the shapes of components such as automotive body panels and engine hoods are usually irregular, after the SMC molding compound is molded, it needs to be cut and processed.

[0003] Regarding the cutting device for SMC molding compounds, there are many existing technologies. For example, the cutting device for producing SMC molding compounds with a waste recycling function in Chinese Patent CN113967937B consists of a cutting machine and an intelligent cutting system. In terms of waste recycling, a crusher and a flipper are provided. The cut materials are put into the crusher by the action of a conveyor belt and gravity. When encountering waste that is difficult to crush, the protection module will stop the motor from rotating to prevent damage to the device. After the crushing is completed, the motor will continue to work to ensure the stable operation of the entire cutting device. After the crusher finishes the crushing work, the flipper pours out the crushed plastic waste, which is convenient for centralized recycling and subsequent reuse processing.

[0004] However, in automotive manufacturing, for the sake of improving production efficiency and reducing costs, SMC molding compounds are often mass-produced. During the cutting process, the tool separates the material by mechanical force. During this process, the friction between the tool and the SMC molding compound will cause energy to be converted into heat. At the same time, due to material fragmentation and wear, fine impurities will be generated, and these impurities are extremely likely to remain on the surface of the cut and formed SMC molding compound. Although the existing SMC molding compound cutting devices can crush and recycle the cut waste chips, they are not convenient for handling the fine impurities adhering to the surface of the cut and formed SMC molding compound. Given the characteristics of mass production, generally, unified treatment is carried out after the cutting of the same batch of SMC molding compounds is completed. During this period, the surface of the cut SMC molding compound will naturally cool down, which causes the impurities remaining on its surface during the cutting process to adhere to it, thereby having an adverse impact on the subsequent processing and use of the SMC molding compound.

[0005] In view of this, we propose an automated cutting device and a cutting process for SMC molding compound production. Summary of the Invention

[0006] The purpose of the present invention is to provide an automated cutting device and a cutting process for SMC molding compound production to solve the problems raised in the above background art.

[0007] To achieve the above object, the object of the present invention is to provide a cutting process for the production of SMC molding compounds. This process includes the following steps:

[0008] Preparation stage: Place the molding compound body on the conveyor belt, ensure that the molding compound body is placed stably, and check whether the cutting assembly, conveyor belt, and crushing mechanism are operating normally to ensure that the functions of all components are intact;

[0009] Transport stage: Start the driving member, so that the conveyor belt connected to the driving member starts, and convey the molding compound body to the middle of the workbench. When the molding compound body is conveyed to the middle of the workbench, the driving member stops operating. At this time, the molding compound body is located at the cutting position;

[0010] Cutting stage: Start the cutting assembly, the cutting assembly moves down, and cut the molding compound body through the tool control mechanism. During the cutting process, the side control mechanism in the cutting assembly cooperates with the conveyor belt to clamp the molding compound body. At the same time, the side control mechanism slides on the surface of the molding compound body to collect and remove the fine impurities generated during the cutting of the molding compound body surface;

[0011] Waste treatment stage: The waste generated by cutting slides off from the side end of the conveyor belt and falls into the crushing mechanism for crushing treatment;

[0012] End stage: After the cutting work is completed, turn off the cutting assembly, start the driving member again, and the auxiliary conveyor belt removes the cut molding compound body for the next treatment.

[0013] The above cutting process for the production of SMC molding compounds uses an automated cutting device, including a workbench. The workbench is a hollow structure. The conveyor belt is rotatably arranged inside the workbench. The inner walls at both ends of the conveyor belt are connected to the driving member. The driving member is used to drive the conveyor belt to start running;

[0014] The driving member includes two gear members meshingly connected inside the conveyor belt. The two gear members are respectively located inside the two ends of the conveyor belt. Both ends of the two gear members are fixedly connected with rotating shafts. The other ends of the four rotating shafts are rotatably arranged on the inner wall of the workbench. A driving motor is fixedly connected to the outer wall of the workbench. The end of one rotating shaft extends out of the surface of the workbench and is fixedly connected to the output shaft of the driving motor. A support plate is fixedly connected to the middle of the workbench. The inner wall of the conveyor belt is attached to the surface of the support plate. The support plate is used to provide support for the conveyor belt;

[0015] The crushing mechanism is located directly below the workbench, and the cutting assembly is located on top of the workbench. The cutting assembly includes a tool control mechanism and a side control mechanism. The tool control mechanism is used to cut the molding compound body conveyed to the center position of the workbench. During the cutting process, the side control mechanism can press and clamp the molding compound body in real time. When the tool control mechanism slides and cuts the molding compound body, the side control mechanism is also used to adhere and absorb the fine dust generated during cutting.

[0016] As a further improvement of this technical solution, the tool control mechanism includes a side frame rod fixedly connected to the top of the workbench. A support cross bar is slidably arranged inside the side frame rod. A cutting robotic arm is movably arranged on the surface of the support cross bar. One end of the cutting robotic arm away from the support cross bar is fixedly installed with a connecting piece, and a tool body for cutting the molding compound body is installed at the bottom end of the connecting piece.

[0017] The tool body includes a housing. One end of the housing is snap-fitted inside the connecting piece, and the other end of the housing extends out of the surface of the connecting piece. A cutting disc is rotatably arranged at the end of the housing away from the connecting piece. Two small gears are rotatably arranged inside the housing, and the two small gears are meshed and connected by a chain. A micro motor is fixedly connected inside the housing near the connecting piece, and one of the small gears near the connecting piece is fixedly connected to the output shaft of the micro motor.

[0018] As a further improvement of this technical solution, the side control mechanism includes a side pressing mechanism and a material collecting mechanism. The side pressing mechanism includes cross support rods rotatably connected to the bottom ends on both sides of the connecting piece. The ends of the cross support rods away from the connecting piece are respectively fixedly connected with a first side pressing plate and a second side pressing plate. During the process of the tool body cutting the molding compound body, the first side pressing plate and the second side pressing plate press on the surface of the molding compound body to evenly distribute the cutting stress generated during the cutting of the molding compound body.

[0019] As a further improvement of this technical solution, the material collecting mechanism includes side grooves opened on both sides of the first side pressing plate and the second side pressing plate. Side rollers are rotatably arranged inside the four side grooves. Material collecting grooves are opened inside the first side pressing plate and the second side pressing plate. The side grooves on both sides of the first side pressing plate are communicated with the material collecting groove inside the first side pressing plate, and the side grooves on both sides of the second side pressing plate are communicated with the material collecting groove inside the second side pressing plate.

[0020] As a further improvement of this technical solution, the crushing mechanism includes a crushing box located at the bottom of the workbench. Two feeding cavities are formed between the two sides of the conveyor belt close to the inner wall of the workbench and the inner wall of the workbench. A crushing roller is rotatably arranged inside the crushing box. A motor is fixedly connected to the outer wall of the crushing box, and the rotating shaft of the crushing roller is fixedly connected to the output shaft of the motor. The crushing box can be turned over for discharging materials.

[0021] As a further improvement of this technical solution, aggregate plates are fixedly connected to both sides of the first side pressing plate and the second side pressing plate.

[0022] As a further improvement of this technical solution, adhesive sleeves for adhesively adsorbing dust are sleeved on the surfaces of the four side rollers.

[0023] As a further improvement of this technical solution, scraping blades are fixedly connected to the tops of one sides of the two material receiving grooves close to the side grooves. The scraping blades are used to scrape the dust adhered to the surfaces of the side rollers when the side rollers rotate.

[0024] As a further improvement of this technical solution, drainage walls are provided on the inner walls of the first side pressing plate and the second side pressing plate close to the tool body.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] 1. In this automatic cutting device and the cutting process for SMC molding compound production, when cutting the sheet-shaped molding compound body, the side control mechanism at the side end of the tool body can adhesively adsorb the generated dust during the moving cutting process of the tool body. Especially timely adsorption during the cutting process can significantly improve the dust adsorption effect, and this adsorption method will not cause additional damage to the surface of the sheet-shaped molding compound body.

[0027] 2. In this automatic cutting device and the cutting process for SMC molding compound production, when cutting the sheet-shaped molding compound body, by utilizing the adsorption property of the conveyor belt surface in combination with the side control mechanism, the sheet-shaped molding compound body can be clamped in real time. When the large waste material cut out is separated from the cut and formed molding compound body, due to the action of the self-gravity of the large waste material and the characteristic of not being bilaterally and stably clamped, it will fall into the crushing box from the blanking cavity for crushing. In this way, the automation effect of the cutting device itself is improved.

[0028] 3. In this automatic cutting device and the cutting process for SMC molding compound production, the side control mechanism can move along with the movement of the tool body. During the process of cutting the sheet-shaped molding compound body, by virtue of this characteristic, the sheet-shaped molding compound body can always be in a real-time fixed state on the conveyor belt surface. Specifically, by clamping both ends of the cutting part and applying appropriate pressure, the cutting stress generated during the cutting process of the molding compound body is effectively evenly distributed. Especially when cutting the sheet-shaped molding compound body for automobiles, evenly distributing the stress generated during cutting can reduce the situation of the sheet-shaped molding compound body breaking, thereby improving the cutting effect.

[0052] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0053] Example 1, please refer to Figure 1 and Figure 2 As shown, the purpose of this embodiment is to provide a cutting process for the production of SMC molding compound. This process includes the following steps:

[0054] Step 1. Preparation stage: Place the molding compound body 10 on the conveyor belt 11, ensure that the molding compound body 10 is placed stably, and check whether the cutting assembly 3, the conveyor belt 11, and the crushing mechanism 2 are operating normally to ensure that the functions of all components are intact;

[0055] Step 2. Transmission stage: Start the driving member 12 to make the conveyor belt 11 connected to the driving member 12 start, and convey the molding compound body 10 to the middle of the workbench 1. When the molding compound body 10 is conveyed to the middle of the workbench 1, the driving member 12 stops operating. At this time, the molding compound body 10 is located at the cutting position;

[0056] Step 3. Cutting stage: Start the cutting assembly 3, and the cutting assembly 3 moves downward to cut the molding compound body 10 through the tool control mechanism 31. During the cutting process, the side control mechanism 32 in the cutting assembly 3 cooperates with the conveyor belt 11 to clamp the molding compound body 10. At the same time, the side control mechanism 32 slides on the surface of the molding compound body 10 to collect and remove the fine impurities generated during the cutting of the surface of the molding compound body 10;

[0057] Step 4. Waste treatment stage: The waste generated by cutting slides off from the side end of the conveyor belt 11 and falls into the crushing mechanism 2 for crushing treatment;

[0058] Step Five, End Stage: After the cutting work is completed, turn off the cutting assembly 3, start the driving member 12 again, and the auxiliary conveyor belt 11 moves the cut molding compound body 10 away for the next processing step.

[0059] Embodiment 2. The cutting process for the production of the above-mentioned SMC molding compound uses an automated cutting device, including a workbench 1. The workbench 1 has a hollow structure. A conveyor belt 11 is rotatably arranged inside the workbench 1. The inner walls at both ends of the conveyor belt 11 are connected to a driving member 12. The driving member 12 is used to drive the conveyor belt 11 to start running. The driving member 12 includes two gear members meshingly connected inside the conveyor belt 11. The two gear members are respectively located inside both ends of the conveyor belt 11. Both ends of the two gear members are fixedly connected with rotating shafts. The other ends of the four rotating shafts are rotatably arranged on the inner wall of the workbench 1. A driving motor is fixedly connected to the outer wall of the workbench 1. The end of one of the rotating shafts extends out of the surface of the workbench 1 and is fixedly connected to the output shaft of the driving motor. A support plate 13 is fixedly connected to the middle of the workbench 1. The inner wall of the conveyor belt 11 is in contact with the surface of the support plate 13. The support plate 13 is used to provide support for the conveyor belt 11. The crushing mechanism 2 is located directly below the workbench 1, and the cutting assembly 3 is located on the top of the workbench 1. The cutting assembly 3 includes a tool control mechanism 31 and a side control mechanism 32. The tool control mechanism 31 is used to cut the molding compound body 10 conveyed to the center position of the workbench 1. During the cutting process, the side control mechanism 32 can press and clamp the molding compound body 10 in real time. When the tool control mechanism 31 performs sliding cutting on the molding compound body 10, the side control mechanism 32 is also used to adhere and absorb the fine dust generated during cutting.

[0060] First, the specific structure of the tool control mechanism 31 is disclosed. The tool control mechanism 31 includes a side frame rod 311 fixedly connected to the top of the workbench 1. A support cross bar 312 is slidably arranged inside the side frame rod 311. A cutting robotic arm 313 is movably arranged on the surface of the support cross bar 312. A connecting member 315 is fixedly installed at the end of the cutting robotic arm 313 away from the support cross bar 312. A tool body 314 for cutting the molding compound body 10 is installed at the bottom end of the connecting member 315.

[0061] The tool body 314 includes a housing. One end of the housing is snap-fitted inside the connecting member 315, and the other end of the housing extends out of the surface of the connecting member 315. A cutting disc is rotatably arranged at the end of the housing away from the connecting member 315. Two small gears are rotatably arranged inside the housing. The two small gears are meshingly connected by a chain. A micro motor is fixedly connected to the inner side of the housing near the connecting member 315. One of the small gears near the connecting member 315 is fixedly connected to the output shaft of the micro motor.

[0062] Refer to Figure 5 and in combination with Figure 6As shown, the support crossbar 312 is slidably arranged inside the side frame bar 311, and the sliding is achieved through a guide rail slider structure. A linear guide rail is arranged inside the side frame bar 311. Sliders are installed at both ends of the support crossbar 312. The position is precisely controlled by a motor drive device. When the motor operates, it drives the sliders to move along the linear guide rail, thereby driving the support crossbar 312 to slide precisely inside the side frame bar 311 to accurately adjust the position of the tool body 314 when cutting the molding compound body 10;

[0063] The sliding of the cutting robotic arm 313 on the support crossbar 312 adopts a gear-rack transmission structure (not shown in the figure). A rack is installed on the support crossbar 312, and a gear is arranged on the cutting robotic arm 313. Precise movement is achieved through motor drive to cut the molding compound body 10 at different positions;

[0064] As Figure 12 shown, for the above-mentioned tool body 314, its working principle is: when it is necessary to cut the molding compound body 10, start the micro motor inside the housing near the connecting piece 315. Its output shaft drives a small gear fixedly connected thereto to rotate. This small gear drives another small gear to rotate synchronously through a chain, thereby causing the cutting disc to rotate and realizing the cutting function of the molding compound body 10.

[0065] The side control mechanism 32 includes a side pressing mechanism 301 and a material collecting mechanism 302. The side pressing mechanism 301 includes cross support rods 321 rotatably connected to the bottom ends on both sides of the connecting piece 315. First side pressing plates 322 and second side pressing plates 323 are respectively fixedly connected to the ends of the cross support rods 321 far from the connecting piece 315. During the process of the tool body 314 cutting the molding compound body 10, the first side pressing plates 322 and the second side pressing plates 323 press on the surface of the molding compound body 10 to evenly distribute the cutting stress generated during the cutting of the molding compound body 10.

[0066] Referring to Figure 6 It can be seen that when the tool body 314 starts to move downward, the cross support rods 321 move downward along with the downward movement of the tool body 314. When the first side pressing plates 322 and the second side pressing plates 323 fixedly connected to the bottom ends of the cross support rods 321 are attached to the surface of the molding compound body 10 to be cut, the tool body 314 stops moving downward (this can be controlled by a sensor or manually. The sensor adopts existing technology and will not be elaborated). At this time, the cutting disc of the tool body 314 is inserted into the interior of the molding compound body 10. As the cutting robotic arm 313 moves, it can drive the tool body 314 to perform moving cutting on the molding compound body 10 along a specified route;

[0067] Sheet molding compound usually has a certain thickness and hardness. During the cutting process, the force exerted by the tool body 314 on it will cause stress concentration inside the material. When the stress exceeds the bearing limit of the material, breakage will occur. Therefore, when using this device for cutting, the first side pressing plate 322 and the second side pressing plate 323 will fit and slide on the surface of the molding compound body 10 as the cross support rod 321 moves, pressurizing the periphery of the cutting seam of the molding compound body 10, which can offset the stress generated by the cutting of the tool body 314 to a certain extent, make the distribution of stress on the molding compound body 10 more uniform, and then reduce the breakage situation when cutting the sheet molding compound body 10 applicable to the automotive field.

[0068] As Figure 5 shown, during the cutting process of the molding compound body 10, it is clamped and fixed by the first side pressing plate 322, the second side pressing plate 323 and the conveyor belt 11. Among them, rubber material is selected as the surface material of the conveyor belt 11, which can generate a large frictional force when contacting the molding compound body 10, effectively reducing the sliding situation of the molding compound body 10 during the cutting process. The rubber material cooperates with the first side pressing plate 322 and the second side pressing plate 323 to ensure that the molding compound body 10 is in a stable state during the cutting process, thereby improving the cutting accuracy and quality.

[0069] Then, the specific structure of the material receiving mechanism 302 is disclosed. The material receiving mechanism 302 includes side grooves 331 opened on both sides of the first side pressing plate 322 and the second side pressing plate 323. Side rollers 332 are rotatably provided inside the four side grooves 331. Material receiving grooves 333 are opened inside the first side pressing plate 322 and the second side pressing plate 323. The side grooves 331 on both sides of the first side pressing plate 322 communicate with the material receiving grooves 333 inside the first side pressing plate 322, and the side grooves 331 on both sides of the second side pressing plate 323 communicate with the material receiving grooves 333 inside the second side pressing plate 323. Among them, the side rollers 332 have a certain gravity, which can improve the fixing effect on the molding compound body 10 while not affecting the sliding of the first side pressing plate 322 and the second side pressing plate 323.

[0070] Refer to Figure 8As shown, the material receiving grooves 333 are respectively formed inside the first side pressing plate 322 and the second side pressing plate 323. At the same time, the side grooves 331 on both sides of the first side pressing plate 322 communicate with the material receiving grooves 333 inside the first side pressing plate 322. The same is true for the second side pressing plate 323. During the operation of the device, the side rollers 332 roll on the surface of the molding compound body 10. During this process, the side rollers 332 can bring the impurities on the surface of the molding compound body 10 into the side grooves 331. Since the side grooves 331 communicate with the material receiving grooves 333, when the side rollers 332 continue to rotate, the impurities can be thrown into the material receiving grooves 333, thereby realizing the collection of impurities such as fine dust on the surface of the molding compound body 10.

[0071] It should be noted that: discharge ports are respectively provided on the sides of the first side pressing plate 322 and the second side pressing plate 323 away from the cross support rod 321. The covers of the two discharge ports are hermetically clamped with the first side pressing plate 322 and the second side pressing plate 323, which is convenient for cleaning the inside of the material receiving grooves 333 after the device stops running.

[0072] Finally, the specific structure of the crushing mechanism 2 is disclosed. The crushing mechanism 2 includes a crushing box 22 located at the bottom of the workbench 1. Two feeding cavities 21 are formed between the two sides of the conveyor belt 11 close to the inner wall of the workbench 1 and the inner wall of the workbench 1. A crushing roller 23 is rotatably provided inside the crushing box 22. A motor is fixedly connected to the outer wall of the crushing box 22. The rotating shaft of the crushing roller 23 is fixedly connected to the output shaft of the motor. The crushing box 22 can be turned over for discharging materials.

[0073] As Figure 4 shown, with the sliding cutting of the tool body 314, the first side pressing plate 322 and the second side pressing plate 323 can clamp the cutting periphery of the molding compound body 10 in real time. When the large waste material cut is separated from the cut and formed molding compound body 10, due to the gravity of the large waste material itself and the movement of the clamped position after cutting, making it not have the characteristic of being clamped on both sides, the waste material will fall into the crushing box 22 from the side end of the conveyor belt 11 for crushing (if the waste material block is large, manual assistance can also be used for dropping).

[0074] When the large waste material generated by cutting the molding compound body 10 falls into the crushing box 22 from the feeding cavity 21, the crushing roller 23 rotatably provided inside the crushing box 22 starts to play a role. The motor fixedly connected to the outer wall of the crushing box 22 starts, and its output shaft drives the rotating shaft of the crushing roller 23 to rotate. During the rotation of the crushing roller 23, the large waste material falling into the crushing box 22 is subjected to extrusion and crushing treatment. When the crushing work is completed, the crushing box 22 can be turned over for discharging materials to pour out the crushed waste material for subsequent treatment or recycling.

[0075] Since there is a certain gap between the first side pressing plate 322 and the second side pressing plate 323 and the cutting seam, in order to improve the collection of cutting impurities, aggregate plates 4 are fixedly connected to both sides of the first side pressing plate 322 and the second side pressing plate 323.

[0076] The improvement lies in: as Figure 6 shown, the aggregate plate 4 can scrape the impurities to the side roller 332 during the movement of the first side pressing plate 322 and the second side pressing plate 323. When the impurities are scraped to the side roller 332, the side roller 332 can more easily collect the fine dust impurities, ensuring that more cutting impurities can be collected and improving the collection efficiency of the cutting impurities.

[0077] Considering the driving situation of the side roller 332 for the fine dust generated during the cutting process, in order to further improve the collection effect of the fine dust, sticky sleeves 5 for sticking and adsorbing miscellaneous dust are sleeved on the surfaces of the four side rollers 332.

[0078] The improvement lies in: as Figure 8 and Figure 9 shown, since the side roller 332 contacts the molding compound body 10 during rotation, it will drive the surrounding air flow, making the fine dust generated during the cutting process more likely to adhere to the side roller 332. The existence of the sticky sleeve 5 increases the adsorption ability of the side roller 332 to the fine dust, so that more fine dust can be adsorbed and finally brought into the side groove 331 by the rotation of the side roller 332. Among them, the sticky sleeve 5 can be made of sticky silicone material, which can fit well with the surface when contacting the SMC molding compound body 10, so as to more effectively stick the fine dust. At the same time, the silicone material has good heat resistance and wear resistance, and can withstand a certain temperature and friction during the molding compound cutting process, and is not easily damaged, ensuring the service life of the sticky sleeve 5 and the continuous adsorption ability to the fine dust.

[0079] Since using the sticky sleeve 5 to stick impurities easily affects the removal effect of the impurities, and then affects the collection of the fine dust by the side roller 332 in the overall process, scraping blades 6 are fixedly connected to the tops of both sides of the two receiving grooves 333 close to the side groove 331. The scraping blades 6 are used to scrape the miscellaneous dust adhered to the surface of the side roller 332 when the side roller 332 rotates.

[0080] The improvement lies in: combined with Figure 10As shown in the figure, scraping blades 6 are fixedly connected to the top of one side of the two material receiving grooves 333 close to the side groove 331. When the side roller 332 rotates, the scraping blades 6 can scrape off the dust adhered to the surface of the side roller 332, which can ensure that the surface of the side roller 332 always maintains good adsorption capacity and continuously and effectively collect fine dust. The scraped dust will fall into the material receiving groove 333, realizing the centralized collection and treatment of fine dust, thereby ensuring the cleanliness and fine dust collection efficiency during the entire cutting process.

[0081] In order to reduce the impurities cut out from falling between the first side pressing plate 322 and the second side pressing plate 323, drainage walls 7 are provided on the inner walls of the first side pressing plate 322 and the second side pressing plate 323 close to the tool body 314.

[0082] The improvement lies in: as Figure 8 shown, the drainage wall 7 is in an arc shape, and its function is to drain the fine dust splashed during the cutting of the tool body 314. Combining Figure 11 , when the tool body 314 cuts the molded plastic body 10, fine dust will be splashed, and the arc-shaped drainage wall 7 can change the movement direction of the fine dust, so that the fine dust can accurately fall outside the aggregate plate 4, thus avoiding the accumulation of impurities between the first side pressing plate 322 and the second side pressing plate 323, which is beneficial to the timely collection and treatment of fine dust.

[0083] To sum up, the working principle of this solution is as follows: First, place the molded plastic body 10 on the conveyor belt 11, turn on the driving part 12, drive the conveyor belt 11 connected to the driving part 12 to start, and convey the molded plastic body 10 to the middle of the workbench 1. After the molded plastic body 10 is in the cutting position, the driving part 12 stops running. Subsequently, the tool control mechanism 31 drives the tool body 314 to start running;

[0084] When the tool body 314 starts to move down, the cross support rod 321 moves down with the downward movement of the tool body 314. When the first side pressing plate 322 and the second side pressing plate 323 fixedly connected to the bottom end of the cross support rod 321 are attached to the surface of the molded plastic body 10 to be cut, the tool body 314 stops moving down. At this time, the cutting disc of the tool body 314 is inserted into the molded plastic body 10. As the cutting robotic arm 313 moves, it can drive the tool body 314 to move and cut the molded plastic body 10 along the specified route. At the same time, the first side pressing plate 322 and the second side pressing plate 323 will fit and slide on the surface of the molded plastic body 10 as the cross support rod 321 moves, applying pressure to the periphery of the cutting seam of the molded plastic body 10, which can offset the stress generated by the cutting of the tool body 314 to a certain extent, make the stress distribution on the molded plastic body 10 more uniform, and then reduce the occurrence of breakage when cutting the sheet molded plastic body 10 applicable to the automotive field;

[0085] During the operation of the device, as the first side pressing plate 322 and the second side pressing plate 323 slide, the side rollers 332 at both ends of the first side pressing plate 322 and the second side pressing plate 323 will roll on the surface of the molding compound body 10. When the side rollers 332 rotate continuously, the adhesive sleeve 5 can be used to increase the adsorption capacity of the side rollers 332 for fine dust, so that more fine dust can be adsorbed and finally brought into the side groove 331 by the rotation of the side rollers 332. When the side rollers 332 rotate, the scraping blade 6 can scrape off the miscellaneous dust adhered to the surface of the side rollers 332, which can ensure that the surface of the side rollers 332 always maintains a good adsorption capacity and continuously and effectively collects fine dust. The scraped-off miscellaneous dust will fall into the material collection groove 333, realizing the centralized collection and treatment of fine dust, thereby ensuring the cleanliness and fine dust collection efficiency during the entire cutting process;

[0086] After cutting, the tool body 314 can move along the specified route again around the molding compound body 10. On the one hand, it can adsorb the miscellaneous dust around the cutting seam of the molding compound body 10, and on the other hand, it can polish the cutting seam of the molding compound body 10. Subsequently, the driving member 12 is started again to output the cut molding compound body 10.
