Description

Technical Field

[0001] This invention relates to the field of plastic processing technology, and in particular to a new energy vehicle interior plastic parts burr removal machine based on waste recycling. Background Technology

[0002] With the rapid development of the global new energy vehicle industry, lightweighting and material recycling have become core directions for industry development. Among these, using recycled plastic waste materials (such as recycled PET, PP, and ABS) to produce automotive interior parts (such as dashboards, door panels, and storage boxes) not only reduces reliance on virgin plastics and petroleum resource consumption, but also achieves carbon emission reduction through a closed-loop material recycling system. This aligns with the environmentally friendly positioning of new energy vehicles and has become a hot research topic in the industry.

[0003] However, due to the complex composition of raw materials (potentially containing different batches and types of recycled materials) and significant differences in melt flowability, recycled plastics are more prone to burrs, flash, or overflow on the surface and edges of interior parts during injection molding or compression molding (the burr rate is 15%-30% higher than that of virgin plastic parts). These burrs not only affect the appearance quality of interior parts (such as surface smoothness and assembly clearance), but may also generate plastic debris due to friction during subsequent assembly or use, affecting the in-vehicle environment and even the safety of electrical components. Therefore, precise removal is essential.

[0004] Currently, the removal of burrs from recycled plastic interior parts mainly relies on traditional equipment, including mechanical scraper-type equipment.

[0005] Recycled plastic burrs often contain trace impurities (such as fiberglass fragments and metal particles mixed in during recycling), and the burr structure is irregular (some areas are "serrated," and some areas are "film-like"). Traditional scraping requires extremely sharp blades (the blade precision needs to be below 0.01mm) to cut the burrs. At the same time, due to the raw materials, the hardness of the burrs varies. In order to ensure the stable operation of the equipment, a large drive power needs to be set, which leads to excessive energy consumption of the equipment.

[0006] During the cutting process, impurities and irregular burrs create high-frequency impacts and friction on the cutting edge, causing it to become dull after 1-2 hours of use (edge ​​wear exceeding 0.03mm). The dulled cutting edge cannot effectively cut the burrs; instead, it "squeezes and deforms" or "tears" them, producing more fine burrs (residual rate exceeding 25%). This necessitates frequent machine shutdowns for replacement or sharpening of the cutting edge, resulting in cumulative downtime exceeding 1.5 hours per shift, severely impacting production efficiency. Summary of the Invention

[0007] Given that existing technologies have high requirements for scrapers and the scrapers are prone to dulling, a new energy vehicle interior plastic parts burr removal machine based on waste recycling is proposed.

[0008] This application provides a new energy vehicle interior plastic parts burr removal machine based on waste recycling, the purpose of which is to improve the scraper, improve its scraping environment, and extend its service life.

[0009] The technical solution of the present invention is as follows: a new energy vehicle interior plastic parts burr removal machine based on waste recycling, including a workbench, a fixed seat and a moving platform set on the top of the workbench, a front panel frame set in front of the moving platform, a cutting device set at the bottom of the front panel frame, and a heating device and a cleaning device set outside the cutting device. The cutting device specifically includes a connecting seat set at the bottom of the front panel frame, a knife holder set at the bottom of the connecting seat, and a knife set inside the knife holder. The bottom of the knife has an inclined cutting edge. The heating device specifically includes a heat-conducting plate disposed on the outside of the blade, a heating plate disposed on the outside of the heat-conducting plate, a fixing plate, and a wiring platform.

[0010] Furthermore, the heat-conducting sheet is designed in a "J" shape, and the heat-conducting sheet is secured to the outside of the tool by the lower bent part.

[0011] Furthermore, the heat-conducting sheet is designed to be parallel to the cutting edge of the tool.

[0012] Furthermore, the cleaning equipment specifically includes a mounting bracket disposed on the outside of the blade holder, a rotating column disposed at the bottom of the mounting bracket, a connecting platform disposed on the outside of the rotating column, a rotating cylinder disposed at the bottom of the connecting platform, a brush disposed on the outside of the rotating cylinder, an air hole opened on the outside of the rotating cylinder, a turbine disposed on the top of the rotating cylinder, and an air inlet connector disposed on the top of the connecting platform. The mounting bracket extends downward to the cutting edge of the tool, and the connecting platform is attached to the lower part of the mounting bracket. The rotating cylinder and the rotating column are respectively distributed at both ends of the connecting platform. The rotating cylinder and the air inlet connector both pass through the connecting platform and are connected within the connecting platform.

[0013] Furthermore, the cleaning device also includes an inner cylinder located inside the rotating cylinder, with an opening on the side of the inner cylinder.

[0014] Furthermore, the cleaning device also includes an extension shaft disposed inside the inner cylinder, an adjustment groove formed on the inner wall of the air inlet connector, and a transmission belt disposed between the rotating column and the air inlet connector. The air intake connector is configured in a "T" shape, with the side interface serving as the air intake port. The extended shaft extends upward through the air intake connector, and a slide rod extending into the adjusting groove is provided on the outside of the extended shaft. The adjusting groove is in the shape of a horizontal "8".

[0015] Furthermore, the rotating cylinder is arranged parallel to the cutting edge of the tool.

[0016] Furthermore, the turbine is engaged with the opening above the air hole, and the turbine drives the rotating cylinder to rotate based on the back of the cutter towards the cutting edge.

[0017] Furthermore, each of the air holes corresponds to a brush.

[0018] The beneficial effects of this invention are: 1. By setting up a heating device, when removing burrs from plastic products, the heating plate is first powered to generate heat, and then the heat is evenly transferred to the cutting edge of the blade through the heat conduction plate. When the heated blade cuts the burrs of the plastic product, it will first soften or melt them, making the cutting process smoother and the processing smoother. The requirement for the sharpness of the blade is reduced. At the same time, the impact and friction on the blade are also less, allowing it to maintain a good cutting effect for a long time.

[0019] By setting a curling section, when the heating plate temperature fluctuates and becomes abnormally high, the two metals in the curling section deform under the influence of different coefficients of thermal expansion. The side with the larger coefficient of thermal expansion is squeezed towards the side with the smaller coefficient of thermal expansion, and the heating plate bends outward, creating a gap between it and the heat-conducting plate. This reduces the heat transferred from the heating plate to the heat-conducting plate, ensures the stability of the cutting edge temperature, and avoids the cutting edge temperature from being too high and affecting the main body of the plastic product.

[0020] 2. By setting up a cleaning device, when scraping burrs, the air blower blows air into the rotating cylinder through the air inlet. When the air flows through the turbine, the turbine drives the rotating cylinder to rotate under the influence of the airflow. During the rotation of the rotating cylinder, the burrs scraped by the blade are swept off by the outer brush. This can prevent the scraped burrs from adhering to or wrapping around the outside of the blade, reduce the probability of burrs melting and adhering to the blade surface due to high temperature, and enable the blade to maintain a good cutting effect for a long time.

[0021] 3. By setting an adjusting groove, initially, the opening of the inner cylinder is tilted towards the cutter. When scraping burrs, the air blower first rapidly draws in air, causing a sudden drop in air pressure inside the air inlet. Under the action of air pressure, the inner cylinder moves towards the air inlet, driving the extension shaft to move. The extension shaft then drives the slide rod to slide upwards along the straight edge of the side within the adjusting groove. Subsequently, the air blower begins to blow air, increasing the air pressure inside the air inlet. The inner cylinder is pushed downwards by the air, and the extension shaft follows suit, moving downwards. Simultaneously, the slide rod slides within the inclined edge in the middle of the adjusting groove. During this process, the extension shaft rotates, causing the inner cylinder to move upwards along the straight edge of the side. Rotate the inner cylinder at a certain angle so that the opening of the inner cylinder faces away from the blade. This blows the scraped burrs away from the blade, resulting in a cleaner cleaning and reducing the impact of airflow on the blade temperature. At the same time, as the extension shaft rotates, the transmission belt drives the rotating column to rotate. The rotating column causes the connecting platform to deflect away from the blade, keeping the brush at a certain distance from the blade. This effectively cleans the scraped burrs while preventing the brush from rubbing against the blade for a long time, which would cause severe wear. It also prevents the burrs adhering to the brush from melting due to heat absorbed from the blade, resulting in stubborn adhesion.

[0022] 4. When the scraping operation stops, the air blower stops blowing air, then rapidly draws in air, causing a sudden drop in air pressure inside the air inlet. Under the pressure, the inner cylinder moves towards the air inlet, driving the extension shaft to move. The extension shaft then drives the slide rod to slide upwards along the straight edge of the side within the adjusting groove. Subsequently, the air blower begins blowing air, increasing the air pressure inside the air inlet. The inner cylinder is pushed downwards by the air, and the extension shaft follows suit, moving downwards. Simultaneously, the slide rod slides within the inclined edge in the middle of the adjusting groove. During this process, the extension shaft rotates, causing the inner cylinder to rotate at a certain angle, so that the opening of the inner cylinder faces the side closer to the blade. This allows the airflow to impact the outside of the blade, cleaning it while also cooling it, causing any attached burrs or debris to fall off or solidify. As the extension shaft rotates, the drive belt drives the rotating column to rotate, causing the connecting platform to deflect towards the blade, bringing the brush into contact with the blade. This further enhances the cleaning effect and helps ensure the cutting performance of the blade. Attached Figure Description

[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] Example 1, referring to Figure 1-6 The first embodiment of the present invention provides a new energy vehicle interior plastic parts burr removal machine based on waste recycling, including a workbench 1, a fixed seat 2 and a moving platform 3 disposed on the top of the workbench 1, a front panel frame 4 disposed in front of the moving platform 3, a cutting device 5 disposed at the bottom of the front panel frame 4, and a heating device 6 and a cleaning device 7 disposed outside the cutting device 5. The cutting device 5 specifically includes a connecting seat 51 disposed at the bottom of the front panel frame 4, a knife holder 52 disposed at the bottom of the connecting seat 51, and a cutting tool 53 disposed inside the knife holder 52.

[0027] Specifically, the top of the fixed base 2 is equipped with a clamp for fixing plastic parts. The moving platform 3 can control the front plate frame 4 and the cutting device 5 to move in the X, Y, and Z coordinate space. The cutting device 5 is located above the fixed base 2 and is fixed to the bottom of the front plate frame 4 by bolts. The tool holder 52 is welded to the bottom of the connecting base 51. The cutting tool 53 is inserted into the inner side of the tool holder 52 and fixed by bolts. The lower end of the cutting tool 53 extends out of the tool holder 52, and the bottom of the cutting tool 53 is provided with an inclined cutting edge.

[0028] The heating device 6 specifically includes a heat-conducting plate 61 disposed on the outside of the blade 53, a heating plate 62 disposed on the outside of the heat-conducting plate 61, a fixing plate 63 and a terminal block 64.

[0029] The heating plate 62 and the fixing plate 63 are welded together. The fixing plate 63 is fixed to the heat-conducting plate 61 by bolts. The terminal block 64 is fixed to the top of the fixing plate 63 and is used to connect the power cord to heat the heating plate 62. The power cord is connected to the power supply. The heat-conducting plate 61 is designed to be parallel to the blade 53, so that the heating at the blade edge is more uniform. Both the heat-conducting plate 61 and the heating plate 62 are made of copper. A curled section is provided at the connection between the heating plate 62 and the fixing plate 63. The curled section is made of two metals with different properties. The coefficient of thermal expansion of the metal on the side closer to the heat-conducting plate 61 is greater than that of the metal on the other side. When the temperature of the heating plate 62 exceeds the set range, the heating plate 62 will bend outward at this point.

[0030] The heating device 6 is roughly divided into five groups, and the heating temperatures corresponding to the five groups of heating plates 62 are 80℃ (±5℃, corresponding to TPE / TPR material processing), 110℃ (±5℃, corresponding to ABS material processing), 130℃ (±5℃, corresponding to PE material processing), 150℃ (±5℃, corresponding to PP material processing), and 170℃ (±5℃, corresponding to PC material processing).

[0031] By setting up the heating device 6, when removing burrs from plastic products, the heating plate 62 is first powered to heat up, and then the heat is evenly transferred to the cutting edge of the blade 53 through the heat-conducting plate 61. When the heated blade 53 cuts the burrs of the plastic products, it will first soften or melt them, making the cutting process smoother and the processing smoother. The requirement for the sharpness of the blade 53 is reduced. At the same time, the impact and friction on the blade 53 are also smaller, allowing it to maintain a good cutting effect for a long time.

[0032] By setting a curling section, when the temperature of the heating plate 62 fluctuates to an abnormally high temperature, the two metals in the curling section deform under the influence of different coefficients of thermal expansion. The side with the larger coefficient of thermal expansion is squeezed towards the side with the smaller coefficient of thermal expansion, and the heating plate 62 bends outward, creating a gap between it and the heat-conducting plate 61. This reduces the heat transferred from the heating plate 62 to the heat-conducting plate 61, ensuring the stability of the cutting edge temperature of the tool 53 and preventing the tool 53 from being too hot and affecting the main body of the plastic product.

[0033] Specifically, the heat-conducting plate 61 is designed in a "J" shape. The heat-conducting plate 61 is secured to the outside of the cutter 53 by the lower bent part. This snap-fit ​​method facilitates the installation and disassembly of the heating device 6.

[0034] Example 2, refer to Figure 1-13This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the cleaning device 7 specifically includes a mounting bracket 71 disposed on the outside of the blade holder 52, a rotating column 72 disposed on the bottom of the mounting bracket 71, a connecting platform 73 disposed on the outside of the rotating column 72, a rotating cylinder 74 disposed on the bottom of the connecting platform 73, a brush 75 disposed on the outside of the rotating cylinder 74, an air hole 76 opened on the outside of the rotating cylinder 74, a turbine 77 disposed on the top of the rotating cylinder 74, and an air inlet connector 78 disposed on the top of the connecting platform 73.

[0035] Specifically, the upper end of the mounting bracket 71 is fixed to the blade holder 52, and the mounting bracket 71 extends downward to the cutting edge of the blade 53. The connecting platform 73 is rotatably connected to the mounting bracket 71 through the rotating column 72. The connecting platform 73 is attached to the lower part of the mounting bracket 71. The rotating cylinder 74 and the rotating column 72 are respectively distributed at both ends of the connecting platform 73. The rotating cylinder 74 is rotatably connected to the bottom of the connecting platform 73. The air inlet connector 78 is snapped into the top of the connecting platform 73. The rotating cylinder 74 and the air inlet connector 78 both pass through the connecting platform 73 and are connected inside the connecting platform 73. The brush 75 is evenly and densely distributed on the surface of the rotating cylinder 74. The rotating cylinder 74 is set parallel to the cutting edge of the blade 53, which facilitates cleaning of the cutting edge. The air inlet connector 78 is connected to an external air blower. The turbine 77 is snapped into the opening above the air hole 76. The turbine 77 drives the rotating cylinder 74 to rotate based on the back of the blade 53 towards the cutting edge, which can sweep the scraped burrs outward and prevent the burrs from adhering to the blade 53.

[0036] By setting up the cleaning device 7, when scraping burrs, the air blowing device blows air into the rotating cylinder 74 through the air inlet 78. When the air flows through the turbine 77, the turbine 77 drives the rotating cylinder 74 to rotate under the influence of the airflow. During the rotation of the rotating cylinder 74, the burrs scraped by the blade 53 are swept off by the outer brush 75. This can prevent the scraped burrs from adhering to or wrapping around the outside of the blade 53, reduce the probability of burrs adhering to the surface of the blade 53 due to high temperature melting, and enable the blade 53 to maintain a good cutting effect for a long time.

[0037] Specifically, the cleaning device 7 also includes an inner cylinder 79 located inside the rotating cylinder 74. The inner cylinder 79 has an opening on its side with an opening angle of 45°, and the inner cylinder 79 is rotatably connected to the rotating cylinder 74.

[0038] The cleaning device 7 also includes an extension shaft 710 disposed inside the inner cylinder 79, an adjustment groove 711 opened on the inner wall of the air inlet connector 78, and a transmission belt 712 disposed between the rotating column 72 and the air inlet connector 78.

[0039] Specifically, the air inlet connector 78 is T-shaped, with the side interface serving as the air inlet and connected to the air blowing device. The lower end of the extension shaft 710 is fixed to the inner cylinder 79, and the extension shaft 710 extends upward through the air inlet connector 78. A slide rod extending into the adjusting slide groove 711 is provided on the outside of the extension shaft 710. The adjusting slide groove 711 is a horizontal figure-eight shape, specifically formed by two isosceles triangles joined diagonally. A guide groove is provided inside the adjusting slide groove 711, allowing the slide rod to travel a figure-eight path within the adjusting slide groove 711. The length of the air inlet connector 78 is shorter than the length of the rotating cylinder 74. The angle between the opening of the inner cylinder 79 and the cutter 53 is 45° and 135° in two states, respectively.

[0040] By setting the adjusting groove 711, initially, the opening of the inner cylinder 79 is tilted towards the cutter 53. When scraping burrs, the air blower first rapidly draws in air, causing a sudden drop in air pressure inside the air inlet 78. Under the action of air pressure, the inner cylinder 79 moves towards the air inlet 78, driving the extension shaft 710 to move. The extension shaft 710 drives the slide rod to slide upward along the straight edge of the side within the adjusting groove 711. Subsequently, the air blower begins to blow air, increasing the air pressure inside the air inlet 78. The inner cylinder 79 is pushed downward by the air, and the extension shaft 710 follows suit, moving downward. Simultaneously, the slide rod slides within the inclined edge in the middle of the adjusting groove 711. During this process, the extension shaft 710 rotates, causing the inner cylinder 79 to rotate. The inner cylinder 79 rotates 90° so that its opening faces away from the blade 53. This blows the scraped burrs away from the blade 53, resulting in a cleaner cleaning and reducing the impact of airflow on the temperature of the blade 53. Simultaneously, as the extension shaft 710 rotates, the transmission belt 712 drives the rotating column 72 to rotate. The rotating column 72 causes the connecting platform 73 to deflect away from the blade 53, keeping the brush 75 at a certain distance from the blade 53. This effectively cleans the scraped burrs while preventing the brush 75 from rubbing against the blade 53 for a long time, thus avoiding severe wear. It also prevents the burrs adhering to the brush 75 from melting due to heat absorbed from the blade 53, thus avoiding stubborn adhesion.

[0041] When the scraping operation stops, the air blower stops blowing air, then rapidly draws in air, causing a sudden drop in air pressure inside the air inlet 78. Under this pressure, the inner cylinder 79 moves towards the air inlet 78, driving the extension shaft 710 to move. The extension shaft 710 then moves the slide rod upwards along the straight edge of the side within the adjusting groove 711. Subsequently, the air blower begins blowing air again, increasing the air pressure inside the air inlet 78. The inner cylinder 79 is pushed downwards by the air, and the extension shaft 710 follows suit, moving downwards. Simultaneously, the slide rod slides along the inclined edge in the middle of the adjusting groove 711. During this process, the extension shaft 710... 10. Rotation of the extension shaft 710 causes the inner cylinder 79 to rotate 90°, so that the opening of the inner cylinder 79 faces the side closer to the cutter 53. This causes the airflow to impact the outside of the cutter 53, cleaning the cutter 53 while also cooling it, causing a small amount of attached burrs and debris to fall off or solidify. During the rotation of the extension shaft 710, the transmission belt 712 drives the rotating column 72 to rotate. The rotating column 72 drives the connecting platform 73 to deflect towards the cutter 53, so that the brush 75 is in contact with the cutter 53, thus further improving the cleaning effect and helping to ensure the cutting effect of the cutter 53.

[0042] Specifically, the air holes 76 correspond one-to-one with the brush 75, so that airflow flows out from the air holes 76, making it convenient to clean the brush 75.

[0043] The remaining structure is the same as that in Example 1.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
