Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of plastic processing, and particularly relates to a new energy automobile interior plastic part burr scraping machine based on waste regeneration. BACKGROUND

[0002] With the rapid development of the global new energy automobile industry, automobile lightweight and material recycling have become the core direction of the industry development. Among them, using plastic waste regeneration raw materials (such as recycled PET, PP, ABS, etc.) to produce automobile interior parts (such as instrument panels, door panels, storage boxes, etc.) can not only reduce the dependence on virgin plastics and reduce the consumption of petroleum resources, but also achieve carbon emission reduction through material recycling, which meets the environmental protection positioning of new energy automobiles and has become a research hotspot in the industry.

[0003] However, due to the complex composition of the raw material (may contain different batches and different types of recycled materials), the poor melt flowability, the surface and edge of the interior part are more likely to produce burrs, flying needles or overflow (the burr occurrence rate is 15%-30% higher than that of virgin plastic parts) during injection molding or compression molding. These burrs not only affect the appearance quality of the interior part (such as surface flatness and assembly gap), but also may generate plastic debris due to friction during subsequent assembly or use, which affects the safety of the in-vehicle environment and electrical components, and therefore must be precisely removed.

[0004] At present, the burr scraping of the recycled plastic interior part mainly relies on traditional equipment, including mechanical scraper type equipment.

[0005] The recycled plastic burr often contains a small amount of impurities (such as glass fiber debris and metal particles mixed during the recycling process), and the burr structure is irregular (partially "sawtooth" and partially "membrane-like"). Traditional scraping relies on a very sharp blade (blade accuracy needs to be below 0.01 mm) to cut off the burr. Due to the hardness of the burr, a large driving power is required to ensure the stable operation of the equipment, which leads to high energy consumption of the equipment.

[0006] During the cutting process, impurities and irregular burrs will cause "high-frequency impact and friction" on the blade, resulting in passivation (blade wear exceeds 0.03 mm) after 1-2 hours of use. The passivated blade cannot effectively cut off the burr, but will "deform" or "tear" the burr, generating more fine flying silk residues (residual rate rises to more than 25%), which requires frequent downtime for blade replacement or grinding. The cumulative downtime of the single-shift equipment exceeds 1.5 hours, which seriously affects the production efficiency. SUMMARY

[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.

[0010] 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.

[0011] 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.

[0012] Furthermore, the heat-conducting sheet is designed to be parallel to the cutting edge of the tool.

[0013] 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.

[0014] 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.

[0015] Furthermore, the cleaning device also includes an inner cylinder located inside the rotating cylinder, with an opening on the side of the inner cylinder.

[0016] 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.

[0017] 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".

[0018] Further, the rotating cylinder is arranged in parallel with the cutting edge of the cutter.

[0019] Further, the turbine is clamped at the opening above the air hole, and the turbine drives the rotating cylinder to rotate based on the direction of the cutting edge of the cutter.

[0020] Further, the air hole and the brush are one-to-one corresponding.

[0021] The beneficial effects of the present application are:

[0022] 1. By arranging the heating device, when removing the plastic product burr, the heating plate is powered to heat, and then the heat is uniformly transmitted to the cutting edge of the cutter through the heat conduction sheet. When the heated cutter cuts the burr of the plastic product, it will first soften or melt, making the cutting process more smooth, and the processing process is also more smooth. The requirement for the sharpness of the cutter is reduced, and at the same time, the impact and friction on the cutter are also smaller, so that it can maintain good cutting effect for a long time.

[0023] By arranging the curling section, when the temperature of the heating plate fluctuates abnormally high, the two kinds of metals in the curling section deform under the influence of different thermal expansion coefficients. The side with large thermal expansion coefficient extrudes the side with small thermal expansion coefficient, the heating plate bends outward between the heat conduction sheet, a gap is formed between the heating plate and the heat conduction sheet, the heat transferred from the heating plate to the heat conduction sheet is reduced, the temperature of the cutting edge is stabilized, and the influence of the high temperature of the cutter on the main body of the plastic product is avoided.

[0024] 2. By arranging the cleaning device, when the burr is scraped, the air blowing device blows air into the rotating cylinder through the air inlet joint. When the air flows through the turbine, the turbine drives the rotating cylinder to rotate under the influence of the air flow. During the rotation of the rotating cylinder, the burr scraped by the cutter is swept off by the brush on the outside. In this way, the scraped burr can be prevented from adhering and winding on the outside of the cutter, the probability of the burr adhering on the surface of the cutter due to high temperature melting is reduced, and the cutter can maintain good cutting effect for a long time.

[0025] 3、By setting the adjusting sliding groove, initially, the opening of the inner cylinder is inclined towards the cutter, when the burrs are removed, the air blowing device first rapidly inhales air, the air pressure in the air inlet connector suddenly decreases, the inner cylinder moves towards the air inlet connector under the action of the air pressure, the inner cylinder drives the extension shaft to move, the extension shaft drives the sliding rod to slide in the adjusting sliding groove, and slides upwards along the straight edge of the side, then the air blowing device starts to blow air, the air pressure in the air inlet connector increases, the inner cylinder is pushed downwards by the air, the extension shaft moves downwards at the same time, and the sliding rod slides in the inclined edge in the middle of the adjusting sliding groove, in this process, the extension shaft rotates, the extension shaft drives the inner cylinder to rotate, so that the opening of the inner cylinder is directed to the side away from the cutter, so that the removed burrs can be blown to the side away from the cutter, the cleaning is more clean, and the influence of the air flow on the temperature of the cutter is also reduced, meanwhile, in the rotating process of the extension shaft, the rotating column is driven to rotate through the transmission belt, the connecting table is deflected to the direction away from the cutter, the brush is kept at a distance from the cutter, the burrs are effectively cleaned, the brush is prevented from rubbing against the cutter for a long time and causing serious wear, and the burrs adhered to the brush are also prevented from melting due to adsorption of heat on the cutter and causing stubborn adhesion.

[0026] 4、When the removing work is stopped, the air blowing device stops blowing air, then the air blowing device rapidly inhales air, the air pressure in the air inlet connector suddenly decreases, the inner cylinder moves towards the air inlet connector under the action of the air pressure, the inner cylinder drives the extension shaft to move, the extension shaft drives the sliding rod to slide in the adjusting sliding groove, and slides upwards along the straight edge of the side, then the air blowing device starts to blow air, the air pressure in the air inlet connector increases, the inner cylinder is pushed downwards by the air, the extension shaft moves downwards at the same time, and the sliding rod slides in the inclined edge in the middle of the adjusting sliding groove, in this process, the extension shaft rotates, the extension shaft drives the inner cylinder to rotate, so that the opening of the inner cylinder is directed to the side close to the cutter, so that the air flow impacts the outer side of the cutter, the cutter is cleaned and cooled at the same time, a small amount of adhered burrs and debris are caused to fall off or solidify, in the rotating process of the extension shaft, the rotating column is driven to rotate through the transmission belt, the connecting table is deflected to the direction close to the cutter, the brush is attached to the cutter, so that the cleaning effect is further improved, and the cutting effect of the cutter is facilitated to be ensured.

DETAILED DESCRIPTION

[0042] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0043] Example 1, refer to Figures 1-6 , the first embodiment of the present invention provides a kind of based on waste regeneration new energy automobile interior plastic part burr scraping machine, including workbench 1, fixed seat 2 and moving platform 3 are set to the top of workbench 1, front plate frame 4 is set to the front of moving platform 3, cutting equipment 5 is set to the bottom of front plate frame 4, it also includes heating equipment 6 and cleaning equipment 7 set to the outside of cutting equipment 5, cutting equipment 5 specifically includes connecting seat 51 set to the bottom of front plate frame 4, knife holder 52 set to the bottom of connecting seat 51, cutter 53 is set to the inside of knife holder 52.

[0044] Specifically, the top of the fixed seat 2 is provided with a clamp for fixing the plastic fittings, the moving platform 3 can control the front plate frame 4 and the cutting device 5 to move in the X, Y, Z three coordinate space, the cutting device 5 is located above the fixed seat 2, the cutting device 5 is fixed below the front plate frame 4 by bolts, the knife holder 52 is welded to the bottom of the connecting seat 51, the cutter 53 is inserted into the inner side of the knife holder 52 and fixed by bolts, the lower end of the cutter 53 extends out of the knife holder 52, and the bottom of the cutter 53 is provided with an inclined cutting edge.

[0045] The heating device 6 specifically includes a heat-conducting sheet 61 provided outside the cutter 53, a heating plate 62 provided outside the heat-conducting sheet 61, a fixed connecting plate 63 and a wiring platform 64.

[0046] The heating plate 62 and the fixed connecting plate 63 are welded, the fixed connecting plate 63 is fixed with the heat-conducting sheet 61 by bolts, the wiring platform 64 is fixed to the top of the fixed connecting plate 63 and used for connecting the power line to heat the heating plate 62, the power line is connected to the power supply, the heat-conducting sheet 61 is designed in parallel with the cutting edge of the cutter 53, so that the heating at the cutting edge is more uniform, the heat-conducting sheet 61 and the heating plate 62 are made of copper, and a curling section is arranged at the connection between the heating plate 62 and the fixed connecting plate 63, the curling section is pressed from two metals with different properties, and the thermal expansion coefficient of the metal on one side of the curling section 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 position.

[0047] The heating device 6 is roughly divided into five groups, and the heating temperatures of 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) respectively.

[0048] By arranging the heating device 6, when removing the plastic product burr, the heating plate 62 is powered first to heat, and then the heat is uniformly transmitted to the cutting edge of the cutter 53 through the heat-conducting sheet 61, so that the cutter 53 is softened or melted when cutting the plastic product burr, the cutting process is smoother, the processing process is more smooth, the requirement for sharpness of the cutter 53 is reduced, and the impact and friction on the cutter 53 are smaller, so that the cutter 53 can maintain good cutting effect for a long time.

[0049] By setting the curling section, when the temperature fluctuation of the heating plate 62 appears abnormally high temperature, the two metals of the curling section are found to deform under the influence of different thermal expansion coefficients. The side with a larger thermal expansion coefficient is pressed to the side with a smaller thermal expansion coefficient. The heating plate 62 bends outward and a gap appears between the heating plate 62 and the heat conduction sheet 61, reducing the heat transferred from the heating plate 62 to the heat conduction sheet 61, ensuring the stability of the cutting edge temperature of the tool 53, and avoiding the influence of the high temperature of the tool 53 on the plastic product body.

[0050] Specifically, the heat conduction sheet 61 is designed as a "J" shape, and the heat conduction sheet 61 is clamped on the outside of the tool 53 by the lower bending part. This clamping method facilitates the installation and disassembly of the heating device 6.

[0051] Embodiment 2, refer to Figures 1-13 For the second embodiment of the present application, which is different from the first embodiment: the cleaning device 7 specifically includes a mounting bracket 71 arranged on the outside of the tool holder 52, a rotating column 72 arranged at the bottom of the mounting bracket 71, a connecting table 73 arranged on the outside of the rotating column 72, a rotating cylinder 74 arranged at the bottom of the connecting table 73, a brush 75 arranged on the outside of the rotating cylinder 74, an air hole 76 opened on the outside of the rotating cylinder 74, a turbine 77 arranged on the top of the rotating cylinder 74, and an air inlet connector 78 arranged on the top of the connecting table 73.

[0052] Specifically, the upper end of the mounting bracket 71 is fixed with the tool holder 52, and the mounting bracket 71 extends downward to the cutting edge of the tool 53. The connecting table 73 is rotatably connected to the mounting bracket 71 through the rotating column 72, and the connecting table 73 is attached to the lower side of the mounting bracket 71. The rotating cylinder 74 and the rotating column 72 are respectively distributed at both ends of the connecting table 73. The rotating cylinder 74 is rotatably connected at the bottom of the connecting table 73. The air inlet connector 78 is clamped on the top of the connecting table 73. The rotating cylinder 74 and the air inlet connector 78 both penetrate the connecting table 73 and are connected in the connecting table 73. The brush 75 is uniformly and densely distributed on the surface of the rotating cylinder 74. The rotating cylinder 74 is arranged in parallel with the cutting edge of the tool 53. In this way, it is convenient to clean the cutting edge. The air inlet connector 78 is connected with an air blowing device. The turbine 77 is clamped on the opening above the air hole 76. The turbine 77 drives the rotating cylinder 74 to rotate towards the cutting edge based on the tool 53. In this way, the burrs scraped off can be swept outwards, avoiding the burrs adhering to the tool 53.

[0053] By setting the cleaning device 7, when scraping the burrs, the air blowing device blows air into the rotating cylinder 74 through the air inlet connector 78. When the air flows through the turbine 77, the turbine 77 drives the rotating cylinder 74 to rotate under the influence of the air flow. In the process of rotating the rotating cylinder 74, the burrs scraped off by the tool 53 are swept off by the brush 75 on the outside. In this way, it can be avoided that the scraped burrs adhere to and entangle on the outside of the tool 53, reducing the probability of the burrs melting and adhering to the surface of the tool 53 due to high temperature, so that the tool 53 can maintain good cutting effect for a long time.

[0054] Specifically, the cleaning device 7 further comprises an inner cylinder 79 which is arranged inside the rotating cylinder 74, and the side surface of the inner cylinder 79 is provided with an opening, the angle of the opening is 45°, and the inner cylinder 79 is rotationally connected with the rotating cylinder 74.

[0055] The cleaning device 7 further comprises an extension shaft 710 which is arranged inside the inner cylinder 79, an adjusting sliding groove 711 which is arranged in the inner wall of the air inlet connector 78, and a transmission belt 712 which is arranged between the rotating column 72 and the air inlet connector 78.

[0056] Specifically, the air inlet connector 78 is arranged in the shape of “T”, the side surface interface is an air inlet which is connected with the air blowing device, the lower end of the extension shaft 710 is fixed with the inner cylinder 79, the extension shaft 710 penetrates out of the air inlet connector 78 in the upward direction, the outer side of the extension shaft 710 is provided with a sliding rod which extends into the inner part of the adjusting sliding groove 711, the adjusting sliding groove 711 is in the shape of a horizontal “8”, specifically, it is formed by two isosceles triangles which are arranged in a diagonal manner, the adjusting sliding groove 711 is provided with a guide groove, so that the sliding rod can move in the shape of “8” in the adjusting sliding groove 711, the length of the air inlet connector 78 is shorter than the length of the rotating cylinder 74, and the angle between the opening of the inner cylinder 79 and the cutter 53 is 45° and 135° respectively in the two states.

[0057] By arranging the adjusting sliding groove 711, initially, the opening of the inner cylinder 79 is inclined towards the cutter 53, when the burrs are scraped, the air blowing device first rapidly inhales air, the air pressure in the air inlet connector 78 suddenly decreases, the inner cylinder 79 moves towards the air inlet connector 78 under the action of the air pressure, the inner cylinder 79 drives the extension shaft 710 to move, the extension shaft 710 drives the sliding rod to slide upwards along the straight side in the adjusting sliding groove 711, then the air blowing device starts to blow air, the air pressure in the air inlet connector 78 increases, the inner cylinder 79 is pushed downwards by the air, the extension shaft 710 moves downwards at the same time, and the sliding rod slides in the inclined side in the middle part of the adjusting sliding groove 711, in this process, the extension shaft 710 is driven to rotate, the extension shaft 710 drives the inner cylinder 79 to rotate by 90°, so that the opening of the inner cylinder 79 is directed to the side which is far away from the cutter 53, in this way, the scraped burrs can be blown to the side which is far away from the cutter 53, so that the cleaning is more clean, and the influence of the air flow on the temperature of the cutter 53 is reduced, at the same time, in the process of the rotation of the extension shaft 710, the rotating column 72 is driven to rotate by the transmission belt 712, the connecting table 73 is deflected to the direction which is far away from the cutter 53 by the rotating column 72, so that the brush 75 is kept at a certain distance from the cutter 53, in this way, the effective cleaning of the scraped burrs is realized, at the same time, the brush 75 is prevented from rubbing against the cutter 53 for a long time, so that serious abrasion is avoided, and the burrs which are attached to the brush 75 are prevented from melting due to the heat adsorbed by the cutter 53, so that stubborn adhesion is avoided.

[0058] When the scraping work is stopped, the air blowing device stops blowing, and then the air blowing device sharply sucks air, the air pressure in the air inlet joint 78 is suddenly reduced, the inner cylinder 79 moves to the direction of the air inlet joint 78 under the action of the air pressure, the extension shaft 710 is moved by the inner cylinder 79, the sliding rod is moved in the adjusting sliding groove 711 by the extension shaft 710, and slides upward along the straight side of the adjusting sliding groove 711. Then the air blowing device starts blowing, the air pressure in the air inlet joint 78 is increased, the inner cylinder 79 is pushed downward by the air, the extension shaft 710 moves downward, and the sliding rod slides in the inclined edge of the middle part of the adjusting sliding groove 711, which drives the extension shaft 710 to rotate, and the extension shaft 710 drives the inner cylinder 79 to rotate by 90°, so that the opening of the inner cylinder 79 faces the side close to the cutter 53. In this way, the airflow impacts the outer side of the cutter 53, which can clean and cool the cutter 53, so that a small amount of attached burr debris falls off or solidifies. In the rotating process of the extension shaft 710, the rotating column 72 is rotated by the transmission belt 712, the connecting table 73 is deflected to the direction close to the cutter 53 by the rotating column 72, the brush 75 is attached to the cutter 53, and the cleaning effect is further improved, which is beneficial to the cutting effect of the cutter 53.

[0059] Specifically, the air holes 76 correspond to the brushes 75 one by one, so that the airflow flows out of the air holes 76, which is convenient for cleaning the brushes 75.

[0060] The remaining structure is the same as that of the embodiment 1.
