The preparation method for a flame-retardant and environmentally friendly automotive interior panel includes the following steps: Step S1: Place the plastic interior panel blank into the inner part of the material frame. The plastic interior panel is intermittently conveyed towards the discharge port inside the conveying cavity through the feeding mechanism. During the conveying process, the outer surface of the plastic interior panel is polished by the polishing device, and at the same time, the pressing device is triggered to press the plastic interior panel and supply lubricating oil.

Step S4: When the polishing device is working, the outer surface of the plastic interior trim panel can be polished by driving the polishing roller. The debris generated by polishing and the lubricating oil will flow into the discharge cavity and be discharged through the spiral feeding rod inside the discharge cavity; Step S5: After the grinding and polishing are completed, as the transfer plate slides, when the temporary storage cavity slides directly above the discharge port, the polished plastic interior trim panel located inside the temporary storage cavity can enter the discharge port from the temporary storage cavity and finally fall onto the conveyor belt for transportation.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting the feeding mechanism, the plastic interior trim panel can be intermittently conveyed from the inside of the material frame to one side of the transfer cavity. By setting the pressing device, the plastic interior trim panel can be pressed to prevent shaking during subsequent grinding and polishing. By setting the polishing device, the bottom of the plastic interior trim panel can be polished to improve the smoothness of the bottom of the plastic interior trim panel; 2. By setting the feeding mechanism, the plastic interior trim panel can be intermittently conveyed from the inside of the material frame to one side of the transfer cavity for individual grinding and polishing. When the feeding mechanism is working, the motor rotates to drive the dial to rotate. During the rotation of the dial, the waist-shaped frame will be driven to swing reciprocally through the lever, and then drive the transfer plate to move reciprocally inside the transfer cavity to intermittently convey the plastic interior trim panel; 3. By setting the pressing device, the plastic interior trim panel can be pressed to prevent shaking during subsequent grinding and polishing. When the temporary storage cavity part of the transfer plate slides below the spring piece during the operation of the pressing device, the restraint on the spring piece will be released, and the spring piece will elastically deform so that the protruding part at the bottom extends into the temporary storage cavity to press the plastic interior trim panel; 4. By the polishing device, the bottom of the plastic interior trim panel can be polished to improve the smoothness of the bottom of the plastic interior trim panel. When the polishing device is working, the outer surface of the plastic interior trim panel can be polished by driving the polishing roller.

Detailed implementation manners

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-9 , the present invention provides a technical solution: a preparation device for a flame-retardant and environmentally friendly automotive interior panel, including a processing table 1. A conveying cavity 14 is opened inside the processing table 1. A material frame 4 is fixed on the top of the processing table 1. A plurality of plastic interior panels 5 are stacked equidistantly between the inner walls of the material frame 4. The bottom of the material frame 4 penetrates into the inside of the conveying cavity 14. A feeding mechanism is arranged inside the conveying cavity 14. A polishing device is arranged on the inner bottom surface of the conveying cavity 14. A discharge port 33 penetrating to the outside is opened on the inner bottom surface of the conveying cavity 14 near one side edge. A pressing device is arranged on the inner top surface of the conveying cavity 14; Two conveying rollers 34 are rotatably connected to the bottom of the processing table 1 near one side edge. A conveyor belt 35 is arranged between the outer surfaces of the two conveying rollers 34. A guide plate 12 is fixed on one side of the processing table 1 near the bottom edge. Two support plates 2 are fixed on the bottom of the processing table 1 near the front and rear sides. Two cushion plates 3 are fixed between the bottoms of the two support plates 2.

[0020] The achieved effect is that the blanks of the plastic interior panels 5 are stacked and placed inside the material frame 4, which is convenient for the subsequent feeding mechanism to convey the plastic interior panels 5 one by one. The plastic interior panels 5 are intermittently conveyed towards the discharge port 33 inside the conveying cavity 14 by the feeding mechanism. During the conveying process, the outer surface of the plastic interior panel 5 is polished by the polishing device, and at the same time, the pressing device is triggered to press the plastic interior panel 5 and supply lubricating oil. When the plastic interior panel 5 is discharged from the discharge port 33, it will fall onto the conveyor belt 35, and the conveyor belt 35 is driven by the conveying rollers 34 to convey the plastic interior panel 5 out.

[0021] Such as Figure 1 , Figure 2 , Figure 4 and Figure 6As shown, the feeding mechanism includes a transfer plate 29, which is slidably connected between the front and rear inner walls of the transfer cavity 14. A temporary storage cavity 30 is formed at the top of the transfer plate 29 near one edge. A groove 36 is formed at the bottom of the transfer plate 29, and both sides of the groove 36 penetrate through both sides of the transfer plate 29 correspondingly. The temporary storage cavity 30 communicates with the groove 36. The temporary storage cavity 30 is located directly below the material frame 4. Reciprocating grooves 6 are formed on the front and rear inner walls of the transfer cavity 14, and both reciprocating grooves 6 penetrate to the outside of the processing table 1. Sliders 11 are slidably connected inside both reciprocating grooves 6, and both sliders 11 are fixedly connected to the transfer plate 29 correspondingly. A fixed column 10 is installed on the slider 11 located on the front side of the processing table 1. A kidney-shaped frame 8 is rotatably connected to the front side of the processing table 1. The fixed column 10 slides between the inner walls of the kidney-shaped frame 8. An installation groove 15 is formed near the bottom edge inside the processing table 1, and a motor 16 is arranged inside the installation groove 15. A dial 7 is fixed to the output end of the motor 16. A dial rod 9 is fixed near the outer surface edge on the front side of the dial 7. The dial rod 9 slides between the inner walls of the kidney-shaped frame 8. Pad strips 49 are fixed to the inner bottom surface of the transfer cavity 14 near the front and rear edges, and one end of both pad strips 49 extends into the groove 36 correspondingly. The outer surfaces of one side of both pad strips 49 are in contact with the inner walls of the groove 36 correspondingly.

[0022] The achieved effect is that when the motor 16 rotates, it drives the dial 7 to rotate. During the rotation of the dial 7, the kidney-shaped frame 8 is driven to swing reciprocally through the dial rod 9. At the same time, the fixed column 10 located on the slider 11 is slidably connected between the inner walls of the kidney-shaped frame 8. Therefore, when the kidney-shaped frame 8 swings, it can drive the transfer plate 29 to move reciprocally inside the transfer cavity 14 to intermittently convey the plastic interior trim panel 5. After the plastic interior trim panel 5 enters the temporary storage cavity 30, during the movement of the transfer plate 29 towards one side of the transfer cavity 14, first, under the constraint of the top of the transfer plate 29 on one side of the temporary storage cavity 30, the bottom of the material frame 4 can be limited and constrained to prevent the materials inside the material frame 4 from sliding down when the transfer plate 29 moves. At the same time, the plastic interior trim panel 5 located inside the temporary storage cavity 30 will be lifted upward under the action of the two pad strips 49, leaving a gap between the bottom of the plastic interior trim panel 5 and the inner bottom surface of the transfer cavity 14, which is convenient for subsequent lubricating oil brushing and grinding and polishing.

[0023] Such as Figure 3 、 Figure 4 、 Figure 7 and Figure 8As shown, the clamping device includes a spring sheet 32, an arc groove 31 is provided on the inner top surface of the transmission chamber 14, one end of the spring sheet 32 ​​is fixed on the inner wall of one side of the arc groove 31, and the other end of the spring sheet 32 ​​slides and fits with the inner wall of the arc groove 31, the spring sheet 32 ​​is curved, and the protruding part of the bottom arc surface of the spring sheet 32 ​​slides and fits on the top of the transmission plate 29, and a transition chamber 18 is provided inside the processing table 1 below the transmission chamber 14, a rectangular groove 21 is provided on the inner bottom surface of the transmission chamber 14, a sponge sheet 22 is arranged between the inner walls of the rectangular groove 21, and a plurality of through openings 20 penetrating into the interior of the transition chamber 18 are equidistantly provided on the inner bottom surface of the rectangular groove 21, and the sponge sheet 22 is located on the other side of the collecting groove 42, and a flow channel 19 is provided on one side of the transition chamber 18, and one end of the flow channel 19 penetrates It passes through the top of the processing table 1, and a docking pipe 13 is fixed on the top of the processing table 1 at the outlet of the flow channel 19. An adjusting chamber 23 is opened inside the processing table 1 near the top edge, and a benchmark 24 is arranged inside the adjusting chamber 23. The top of the benchmark 24 slides through the top of the processing table 1, and the bottom of the benchmark 24 slides through the inside of the arc groove 31 and fits with the top of the spring sheet 32. A scale bar 25 is arranged on the outer surface of the benchmark 24 near the top edge. A fixing plate 26 is installed on the outer surface of the benchmark 24, and the fixing plate 26 is slidably connected between the inner walls of the adjusting chamber 23. A reset spring 27 is fixed to the bottom of the fixing plate 26, and the bottom of the reset spring 27 is fixed to the inner bottom surface of the adjusting chamber 23. A through hole 28 is opened on one side of the benchmark 24, and the through hole 28 is connected with the flow channel 19.

[0024] The effect achieved is that when the temporary storage cavity 30 of the transmission plate 29 slides below the spring sheet 32, the constraint of the top of the transmission plate 29 on the protruding portion of the bottom of the spring sheet 32 ​​will be released. At this time, the spring sheet 32 ​​will produce elastic deformation to extend the bottom protruding portion to the inside of the temporary storage cavity 30 to press the plastic interior panel 5. When the spring sheet 32 ​​elastically deforms downward, the upward lifting constraint on the benchmark 24 will be released. At this time, under the elastic force of the return spring 27, the benchmark 24 is driven to slide downward, so that the through hole 28 and the flow channel 19 are connected to each other, so that the external lubricating oil can enter the transition cavity 18 through the flow channel 19. At the same time, the downward scale of the scale bar 25 on the benchmark 24 can be observed from the outside to obtain the elastic deformation degree of the spring sheet 32, so as to judge whether the plastic interior panel 5 is effectively pressed. When the external lubricating oil is inside the transition cavity 18, it will spread through the through hole 20 and penetrate into the sponge sheet 22, and the lubricating oil will be evenly applied to the bottom of the plastic interior panel 5 through the sponge sheet 22.

[0025] like Figure 4 , Figure 5 , Figure 8 and Figure 9As shown in the figure, the polishing device includes a polishing roller 41. Inside the processing table 1, a cylindrical cavity 38 is opened below the conveying cavity 14. The top of the cylindrical cavity 38 penetrates into the inside of the conveying cavity 14. The polishing roller 41 is rotatably installed between the inner walls on both sides of the cylindrical cavity 38. The top of the polishing roller 41 extends into the inside of the conveying cavity 14. Inside the processing table 1, a discharge cavity 39 is opened below the cylindrical cavity 38. The top of the discharge cavity 39 penetrates into the inside of the cylindrical cavity 38. One end of the discharge cavity 39 near the bottom edge communicates with the outside of the processing table 1. A spiral feeding rod 40 is rotatably connected between the inner walls on both sides of the discharge cavity 39. On the inner bottom surface of the conveying cavity 14, near one side of the cylindrical cavity 38, a collecting groove 42 is opened. On the inner bottom surface of the collecting groove 42, a plurality of side openings 43 penetrating into the inside of the cylindrical cavity 38 are equidistantly opened. On the inner bottom surface of the conveying cavity 14, between the cylindrical cavity 38 and the collecting groove 42, a scraping plate 37 is obliquely fixed. The top of the scraping plate 37 extends obliquely upward above the polishing roller 41. One side outer surface of the scraping plate 37 obliquely extends to one side inner wall of the collecting groove 42.

[0026] The achieved effect is that before the plastic interior trim panel 5 is conveyed to the polishing roller 41, the lubricating oil liquid smeared on the bottom of the plastic interior trim panel 5 is evenly brushed by the obliquely arranged scraping plate 37, facilitating subsequent grinding lubrication. The excess lubricating oil liquid flows into the collecting groove 42 under the guidance of the inclined surface on one side of the scraping plate 37, and enters the inside of the cylindrical cavity 38 through the side openings 43 in the collecting groove 42, and finally enters the discharge cavity 39. The plastic interior trim panel 5 after passing through the scraping plate 37 can improve the surface finish of the outer surface through the polishing and grinding of the polishing roller 41 during the pushing process. During the polishing and grinding, grinding dust will be generated. After the dust and the lubricating oil liquid are mixed, they will flow downward from the opening on one side of the cylindrical cavity 38 under the blockage of the inclined surface on the other side of the inclined scraping plate 37, and finally flow into the discharge cavity 39. Inside the discharge cavity 39, the generated grinding waste is discharged to the outside through the spiral feeding rod 40.

[0027] As Figure 5 and Figure 9 As shown in the figure, a transmission cavity 44 is opened near the front side edge inside the processing table 1. One side of the transmission cavity 44 communicates with the installation groove 15. An annular belt pulley 17 is fixed on the outer surface of the output end of the motor 16. On the rear inner wall of the transmission cavity 44, near the other side edge, a driving gear 47 is rotatably connected. On the rear inner wall of the transmission cavity 44, above the driving gear 47, a driven gear 46 is rotatably connected. The driving gear 47 meshes with the driven gear 46. The rear side of the driving gear 47 is connected to one end of the spiral feeding rod 40. The rear side of the driven gear 46 is connected to one end of the polishing roller 41. A driven belt pulley 48 is fixed on the front side of the driving gear 47. A belt 45 is connected between the driven belt pulley 48 and the annular belt pulley 17.

[0028] The effect achieved is that the annular pulley 17 is driven to rotate by the rotation of the motor 16. Since the annular pulley 17 is connected to the driven pulley 48 by the belt 45, the driven pulley 48 can be driven to rotate synchronously. Since the driven pulley 48 is fixed on the driving gear 47, and the driving gear 47 and the driven gear 46 are meshed with each other, when the motor 16 rotates, the driving gear 47 and the driven gear 46 can be driven to rotate synchronously, thereby making the spiral feeding rod 40 and the polishing roller 41 rotate synchronously.

[0029] The main problem solved by this embodiment is: by setting a feeding mechanism, the plastic interior panel 5 can be intermittently transported from the inside of the material frame 4 to one side of the conveying chamber 14, so that the plastic interior panel 5 can be polished one by one, and it is also convenient for external operators to load the plastic interior panel 5. By setting a pressing device, the plastic interior panel 5 can be pressed to prevent shaking during subsequent grinding and polishing, and the flow channel 19 will be opened during pressing to allow external lubricating oil to enter the transition chamber 18, and finally be brushed on the bottom of the plastic interior panel 5 through the sponge sheet 22. The lubricating oil can eliminate dust generated by polishing and grinding during polishing, and lubricate the polishing and grinding parts at the same time. By setting a polishing device, the bottom of the plastic interior panel 5 can be polished to improve the smoothness of the bottom of the plastic interior panel 5, and the debris and lubricating oil mixture generated by grinding during polishing can be sent to the discharge chamber 39 and discharged through the spiral feeding rod 40, which solves the current technical problem that a large amount of fine plastic powder is generated during the polishing and grinding of the interior panel, and the powder floats in the air and is inhaled into the lungs of the operator, which seriously endangers the health of the operator.

[0030] For example, in one embodiment, the present invention further provides a method for preparing a flame retardant and environmentally friendly automobile interior panel, which is applied to a device for preparing a flame retardant and environmentally friendly automobile interior panel as described above, and comprises the following steps: Step S1: Put the plastic interior panel 5 blank into the material frame 4, and intermittently convey the plastic interior panel 5 to the discharge port 33 in the conveying chamber 14 through the feeding mechanism. During the conveying process, the outer surface of the plastic interior panel 5 is polished and polished by the polishing device, and the pressing device is triggered to press the plastic interior panel 5 and supply lubricating oil; Step S2: When the feeding mechanism is working, the motor 16 rotates to drive the dial 7 to rotate. During the rotation of the dial 7, the lever 9 drives the waist-shaped frame 8 to swing back and forth, thereby driving the conveying plate 29 to reciprocate inside the conveying chamber 14 to intermittently convey the plastic interior panel 5; Step S3: When the pressing device is working, when the temporary storage cavity 30 of the transmission plate 29 slides to below the spring sheet 32, the constraint on the spring sheet 32 ​​is released, and the spring sheet 32 ​​is elastically deformed so that the bottom protruding portion extends to the inside of the temporary storage cavity 30 to press the plastic interior panel 5. At the same time, the rod 24 slides downward to make the through hole 28 and the flow channel 19 communicate with each other, so that the external lubricating oil can enter the transition cavity 18 through the flow channel 19; Step S4: When the polishing device is working, the outer surface of the plastic interior panel 5 can be polished by driving the polishing roller 41, and the debris generated by the polishing together with the lubricating oil will flow into the discharge cavity 39 and be discharged from the discharge cavity 39 through the spiral feeding rod 40; Step S5: After grinding and polishing is completed, as the conveying plate 29 slides, when the temporary storage chamber 30 slides to just above the discharge port 33, the polished plastic interior panel 5 inside the temporary storage chamber 30 can enter the discharge port 33 from the temporary storage chamber 30, and finally fall onto the conveyor belt 35 for transportation.
