Description

Technical Field

[0001] The invention relates to the technical field of SMC molding compound production, in particular to an automatic cutting device and a cutting process for producing SMC molding compound. Background Art

[0002] In the automotive field, SMC molding compounds are mainly used in the manufacture of body panels, engine hoods and other parts. Since the appearance of automobile body panels, engine hoods and other parts is usually irregular, SMC molding compounds need to be cut after molding; There are many existing technologies for cutting devices for SMC molding materials, such as the Chinese patent CN113967937B, which discloses a cutting device for producing SMC molding materials with a waste recycling function. The device 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 through a conveyor belt and gravity. When encountering waste materials that are difficult to crush, the protection module stops the motor from rotating to prevent damage to the device. After the crushing is completed, the motor continues to work, ensuring the stable operation of the entire cutting device. After the crushing is completed by the crusher, the flipper pours out the crushed plastic waste, which is convenient for centralized recycling and subsequent reuse. However, in automobile manufacturing, SMC molding materials are often manufactured in batches for the purpose of improving production efficiency and reducing costs. During the cutting process, the tool separates the material with the help of mechanical force. During this process, the friction between the tool and the SMC molding material will cause energy to be converted into heat energy. At the same time, fine impurities will be generated due to material crushing and wear. These impurities are very likely to remain on the surface of the cut and formed SMC molding material. Although the SMC molding material cutting device in the prior art can crush and recycle the waste chips after cutting, it is not convenient to handle the fine impurities adhering to the surface of the SMC molding material after cutting and forming. In view of the characteristics of batch manufacturing, the SMC molding materials of the same batch are generally treated uniformly after the cutting is completed. During this period, the surface of the cut SMC molding material will naturally cool down, which makes the impurities remaining on its surface during the cutting process stick to it, thereby bringing adverse effects to the subsequent processing and use of the SMC molding material. In view of this, we propose an automated cutting device and a cutting process for SMC molding compound production. Summary of the invention

[0003] The object of the present invention is to provide an automated cutting device and a cutting process for producing SMC molding compounds to solve the problems raised in the above background technology.

A cutting disc is rotatably provided at the end of the shell away from the connecting piece, and two small gears are rotatably provided inside the shell. The two small gears are meshed and connected by a chain. A micro motor is fixedly connected inside the shell on one side close to the connecting piece, and a small gear close to the connecting piece is fixedly connected to the output shaft of the micro motor.

[0007] As a further improvement of the present technical solution, the side control mechanism includes a side pressure mechanism and a material receiving mechanism, the side pressure mechanism includes a cross support rod rotatably connected to the bottom ends on both sides of the connecting member, the end of the cross support rod away from the connecting member is respectively fixedly connected with a first side pressure plate and a second side pressure plate, and when the tool body is cutting the molding material body, the first side pressure plate and the second side pressure plate are pressed on the surface of the molding material body to uniformly generate the cutting stress generated during the cutting process of the molding material body.

In the automatic cutting device and the cutting process for SMC molding plastic production, when cutting the sheet molding plastic body, the sheet molding plastic body can be clamped in real time by utilizing the adsorption of the conveyor belt surface combined with the side control mechanism. When the cut large piece of waste is separated from the cut molding plastic body, due to the gravity of the large piece of waste itself and the characteristics of no stable clamping on both sides, it will fall from the feeding cavity into the crushing box for crushing, thus improving the automation effect of the cutting device itself; 3.

Especially when cutting the sheet molding material body for automobiles, the stress generated during the uniform cutting can reduce the rupture of the sheet molding material body, thereby improving the cutting effect.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Example 1, please refer to Figure 1 and Figure 2As shown, the purpose of this embodiment is to provide a cutting process for producing SMC molding materials, and the process includes the following steps: Step 1, preparation stage: Place the molded plastic body 10 on the conveyor belt 11, ensure that the molded plastic body 10 is placed stably, check whether the cutting assembly 3, the conveyor belt 11 and the crushing mechanism 2 are operating normally, and ensure that all components are functioning properly; Step 2, transport stage: turn on the driving member 12, start the conveyor belt 11 connected to the driving member 12, and transport the molded plastic body 10 to the middle of the workbench 1. When the molded plastic body 10 is transported to the middle of the workbench 1, the driving member 12 stops running, and the molded plastic body 10 is at the cutting position; Step 3, cutting stage: start the cutting assembly 3, the cutting assembly 3 moves downward, and the molded plastic body 10 is cut 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 molded plastic body 10. At the same time, the side control mechanism 32 slides on the surface of the molded plastic body 10 to collect and remove dust from the fine impurities generated when the surface of the molded plastic body 10 is cut; Step 4, waste material processing stage: the waste material generated by cutting slides down from the side end of the conveyor belt 11 and falls into the crushing mechanism 2 for crushing; Step 5, end stage: After the cutting work is completed, the cutting assembly 3 is closed, the driving member 12 is started again, and the auxiliary conveyor belt 11 removes the cut molding material body 10 for the next step of processing.

[0019] Embodiment 2: The cutting process of the above-mentioned SMC molding compound production adopts an automated cutting device, including a workbench 1, the workbench 1 is a hollow structure, a conveyor belt 11 is rotatably arranged inside the workbench 1, and the inner walls at both ends of the conveyor belt 11 are connected to a driving member 12, and 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 to the inside of the conveyor belt 11, the two gear members are respectively located inside the two ends of the conveyor belt 11, both ends of the two gear members are fixedly connected with a rotating shaft, and the other ends of the four rotating shafts are rotatably arranged on the inner wall of the workbench 1, and the outer wall of the workbench 1 is fixedly connected with a driving motor, and the end of one of the rotating shafts extends out of the surface of the workbench 1 and is connected to the output of the driving motor. The output shaft is fixedly connected, and a support plate 13 is fixedly connected to the middle of the workbench 1. The inner wall of the conveyor belt 11 fits with the surface of the support plate 13, and 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 molded plastic body 10 transported to the center position of the workbench 1. During the cutting process, the side control mechanism 32 can press and clamp the molded plastic body 10 in real time. When the tool control mechanism 31 performs sliding cutting on the molded plastic body 10, the side control mechanism 32 is also used to stick and absorb fine dust produced by cutting.

[0020] 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 mechanical arm 313 is movably arranged on the surface of the support cross bar 312, and a connecting piece 315 is fixedly installed at one end of the cutting mechanical arm 313 away from the support cross bar 312, and a tool body 314 for cutting the molded plastic body 10 is installed at the bottom end of the connecting piece 315; The tool body 314 includes a shell, one end of which is snap-fitted into the interior of the connecting member 315, and the other end of the shell extends out of the surface of the connecting member 315. A cutting disc is rotatably provided at one end of the shell away from the connecting member 315, and two small gears are rotatably provided inside the shell, and the two small gears are meshedly connected by a chain. A micro motor is fixedly connected to the interior of the shell close to the connecting member 315, and a small gear close to the connecting member 315 is fixedly connected to the output shaft of the micro motor.

[0021] See also Figure 5 Combined with Figure 6As shown, the support cross bar 312 is slidably arranged inside the side frame rod 311, and the sliding is realized by a guide rail slider structure. A linear guide rail is arranged inside the side frame rod 311, and sliders are installed at both ends of the support cross bar 312. The position is accurately controlled by a motor drive device. When the motor is running, the slider is driven to move along the linear guide rail, thereby driving the support cross bar 312 to accurately slide inside the side frame rod 311, so as to realize accurate adjustment of the position of the tool body 314 when cutting the molded plastic body 10; The cutting mechanical arm 313 slides on the supporting crossbar 312 using a gear rack transmission structure (not shown in the figure). A rack is installed on the supporting crossbar 312, and a gear is set on the cutting mechanical arm 313. The motor drives the cutting mechanical arm 313 to achieve precise movement to cut the molding material body 10 at different positions. like Fig.12 As shown, the working principle of the above-mentioned tool body 314 is as follows: when it is necessary to cut the molded plastic body 10, the micro motor inside the shell close to the connecting piece 315 is started, and its output shaft drives a small gear fixedly connected to it to rotate, and the small gear drives another small gear to rotate synchronously through a chain, thereby rotating the cutting disc to realize the cutting function of the molded plastic body 10.

[0022] The side control mechanism 32 includes a side pressure mechanism 301 and a material receiving mechanism 302. The side pressure mechanism 301 includes a cross support rod 321 rotatably connected to the bottom ends of both sides of the connecting member 315. The end of the cross support rod 321 away from the connecting member 315 is fixedly connected with a first side pressure plate 322 and a second side pressure plate 323 respectively. When the tool body 314 is cutting the molding material body 10, the first side pressure plate 322 and the second side pressure plate 323 are pressed on the surface of the molding material body 10 to even out the cutting stress generated during the cutting process of the molding material body 10.

[0023] See also Figure 6 It can be seen that when the tool body 314 starts to move downward, the cross support rod 321 moves downward with the tool body 314. When the first side pressure plate 322 and the second side pressure 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 downward (this can be controlled by a sensor or manually. The sensor adopts the existing technology and is not described in detail). At this time, the cutting disc of the tool body 314 is inserted into the interior of the molded plastic body 10. As the cutting robot arm 313 moves, it can drive the tool body 314 to move and cut the molded plastic body 10 according to a specified route. Sheet molding material usually has a certain thickness and hardness. During the cutting process, the force applied to it by the tool body 314 will cause stress concentration inside the material. When the stress exceeds the bearing limit of the material, it will be damaged. Therefore, when using the present device for cutting, the first side pressure plate 322 and the second side pressure plate 323 will slide on the surface of the molding material body 10 with the movement of the cross support rod 321, and pressurize the periphery of the cutting seam of the molding material 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 molding material body 10 more even, and then reduce the possibility of damage when cutting the sheet molding material body 10 suitable for the automotive field.

[0024] like Figure 5 As shown, during the cutting process, the molded plastic body 10 is clamped and fixed by the first side pressure plate 322, the second side pressure plate 323 and the conveyor belt 11, wherein rubber material is selected as the surface material of the conveyor belt 11, which can generate a large friction force when it contacts with the molded plastic body 10, and can effectively reduce the sliding of the molded plastic body 10 during the cutting process. The rubber material cooperates with the first side pressure plate 322 and the second side pressure plate 323 to ensure that the molded plastic body 10 is in a stable state during the cutting process, thereby improving the cutting accuracy and quality.

[0025] 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 pressure plate 322 and the second side pressure plate 323. Side rollers 332 are rotatably provided inside the four side grooves 331. Material receiving grooves 333 are opened inside the first side pressure plate 322 and the second side pressure plate 323. The side grooves 331 on both sides of the first side pressure plate 322 are communicated with the material receiving groove 333 inside the first side pressure plate 322, and the side grooves 331 on both sides of the second side pressure plate 323 are communicated with the material receiving groove 333 inside the second side pressure plate 323. The side rollers 332 themselves have a certain gravity, which can improve the fixing effect of the molding material body 10 without affecting the sliding of the first side pressure plate 322 and the second side pressure plate 323.

[0026] See also Figure 8As shown, the material receiving groove 333 is respectively opened inside the first side pressure plate 322 and the second side pressure plate 323. At the same time, the side grooves 331 on both sides of the first side pressure plate 322 are connected with the material receiving groove 333 inside the first side pressure plate 322. The situation of the second side pressure plate 323 is the same. During the operation of the device, the side rollers 332 will roll on the surface of the molding material body 10. During this process, the side rollers 332 can bring impurities on the surface of the molding material body 10 into the side grooves 331. Since the side grooves 331 and the material receiving groove 333 are connected, when the side rollers 332 continue to rotate, the impurities can be thrown into the material receiving groove 333, thereby realizing the collection of impurities such as fine dust on the surface of the molding material body 10.

[0027] It should be noted that: the first side pressure plate 322 and the second side pressure plate 323 are both provided with discharge ports on the side away from the cross support rod 321, and the cover plates of the two discharge ports are sealed and clamped with the first side pressure plate 322 and the second side pressure plate 323, so as to facilitate cleaning of the receiving trough 333 after the device stops running.

[0028] 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, and two material discharge 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 provided inside the crushing box 22 for rotation. The outer wall of the crushing box 22 is fixedly connected to a motor. The rotating shaft of the crushing roller 23 is fixedly connected to the output shaft of the motor, and the crushing box 22 can be flipped to discharge materials.

[0029] like Figure 4 As shown, with the sliding cutting of the tool body 314, the first side pressure plate 322 and the second side pressure plate 323 can clamp the cutting periphery of the molding material body 10 in real time. When the cut large piece of waste is separated from the cut and formed molding material body 10, since the large piece of waste has its own gravity and the clamping position is moved after cutting, so that it does not have the characteristics of clamping on both sides, the waste will fall from the side end of the conveyor belt 11 into the crushing box 22 for crushing (if the waste block is large, it can also be manually assisted to fall).

[0030] When the large pieces of waste generated by cutting the molding material body 10 fall into the crushing box 22 from the feeding cavity 21, the crushing roller 23 rotatably arranged inside the crushing box 22 starts to play a role, and the motor fixedly connected to the outer wall of the crushing box 22 is started, and its output shaft drives the rotating shaft of the crushing roller 23 to rotate. During the rotation process, the crushing roller 23 squeezes and crushes the large pieces of waste falling into the crushing box 22. When the crushing work is completed, the crushing box 22 can be turned over to discharge the material, and the crushed waste is poured out for subsequent processing or recycling.

[0031] Since there is a certain gap between the first side pressure plate 322 and the second side pressure plate 323 and the cutting seam, in order to improve the collection of cutting impurities, both sides of the first side pressure plate 322 and the second side pressure plate 323 are fixedly connected with a collecting plate 4.

[0032] The improvement is: Figure 6 As shown, the collecting plate 4 can scrape the impurities to the side roller 332 during the movement of the first side pressure plate 322 and the second side pressure 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 cut impurities can be collected, thereby improving the collection efficiency of the cut impurities.

[0033] Considering that the side rollers 332 drive the fine dust generated during the cutting process, in order to further improve the collection effect of the fine dust, the surfaces of the four side rollers 332 are all sleeved with sticky sleeves 5 for sticking and adsorbing the miscellaneous dust.

[0034] The improvement is: Figure 8 and Fig. 9 As shown, since the side roller 332 contacts the molding material body 10 during the rotation, it will drive the surrounding air flow, making it easier for the fine dust generated during the cutting process to adhere to the side roller 332, and the presence of the adhesive sleeve 5 increases the adsorption capacity of the side roller 332 for the fine dust, so that more fine dust can be adsorbed and finally brought into the side groove 331 through the rotation of the side roller 332, wherein the adhesive sleeve 5 can be made of a sticky silicone material, which can better fit the surface when in contact with the SMC molding material body 10, thereby more effectively adhering to the fine dust. At the same time, the silicone material has good heat resistance and wear resistance. During the molding material cutting process, it can withstand a certain temperature and friction and is not easily damaged, thereby ensuring the service life of the adhesive sleeve 5 and its continuous adsorption capacity for fine dust.

[0035] Since the sticky sleeve 5 is used to stick to the impurities, it is easy to affect the removal effect of the impurities, and then affect the collection of fine dust by the side roller 332 in the overall process. Therefore, the top of the two receiving troughs 333 close to the side trough 331 is fixedly connected with a scraper blade 6. The scraper blade 6 is used to scrape off the dust stuck on the surface of the side roller 332 when the side roller 332 rotates.

[0036] The improvement lies in: combining Fig.10As shown, the top of one side of the two receiving troughs 333 close to the side trough 331 is fixedly connected with a scraper blade 6. When the side roller 332 rotates, the scraper blade 6 can scrape off the dust stuck on the surface of the side roller 332, so as to ensure that the surface of the side roller 332 always maintains a good adsorption capacity and continuously and effectively collects fine dust. The scraped dust will fall into the receiving trough 333, realizing the centralized collection and treatment of the fine dust, thereby ensuring the cleanliness and fine dust collection efficiency during the entire cutting process.

[0037] In order to reduce the amount of impurities cut off from falling between the first side pressure plate 322 and the second side pressure plate 323 , a drainage wall 7 is provided on the inner wall of the first side pressure plate 322 and the second side pressure plate 323 close to the tool body 314 .

[0038] The improvement is: Figure 8 As shown, the drainage wall 7 is in an arc shape, and its function is to drain the fine dust splashed when the tool body 314 is cut. Fig.11 When the tool body 314 cuts the molding material body 10, flying fine dust will be generated, and the arc-shaped drainage wall 7 can change the movement direction of the fine dust, so that the fine dust can accurately fall on the outside of the collecting plate 4, thereby avoiding the accumulation of impurities between the first side pressure plate 322 and the second side pressure plate 323, which is conducive to the timely collection and treatment of the fine dust.

[0039] In summary, the working principle of the present solution is as follows: first, the molded plastic body 10 is placed on the conveyor belt 11, the driving member 12 is turned on, the conveyor belt 11 connected to the driving member 12 is driven to start, and the molded plastic body 10 is conveyed to the middle of the workbench 1. After the molded plastic body 10 is located at the cutting position, the driving member 12 stops running, and then the tool control mechanism 31 drives the tool body 314 to start running; When the tool body 314 starts to move downward, the cross support rod 321 moves downward with the tool body 314. When the first side pressure plate 322 and the second side pressure 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 downward. At this time, the cutting disc of the tool body 314 is inserted into the interior of the molded plastic body 10. With the movement of the cutting robot arm 313, the tool body 314 can be driven to move and cut the molded plastic body 10 according to a prescribed route. At the same time, the first side pressure plate 322 and the second side pressure plate 323 will slide on the surface of the molded plastic body 10 with the movement of the cross support rod 321, and pressurize 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, so that the stress is more evenly distributed on the molded plastic body 10, thereby reducing the possibility of damage when cutting the sheet molded plastic body 10 suitable for the automotive field. During the operation of the device, as the first side pressure plate 322 and the second side pressure plate 323 slide, the side rollers 332 located at both ends of the first side pressure plate 322 and the second side pressure plate 323 will roll on the surface of the molded plastic body 10. When the side rollers 332 continue to rotate, the adhesive sleeves 5 can increase the adsorption capacity of the side rollers 332 for fine dust, so that more fine dust can be adsorbed and eventually brought into the side grooves 331 through the rotation of the side rollers 332. When the side rollers 332 rotate, the scraper blades 6 can scrape off the dust stuck on the surface of the side rollers 332. This ensures that the surface of the side rollers 332 always maintains a good adsorption capacity and continuously and effectively collects fine dust. The scraped dust will fall into the collecting groove 333, realizing the centralized collection and treatment of the fine dust, thereby ensuring the cleanliness and fine dust collection efficiency of the entire cutting process. After cutting is completed, the tool body 314 can be moved again along the specified route around the molding material body 10. On the one hand, it can absorb dust around the cutting seam of the molding material body 10, and on the other hand, it can polish the cutting seam of the molding material body 10. Then, the driving part 12 is started again to output the cut molding material body 10.
