Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic processing technology, and more specifically, to an automatic feeding machine for plastic processing. Background Technology
[0002] Plastics processing is an industrial process that uses synthetic resins (such as polyethylene and polypropylene) or natural resins (such as shellac and rosin) as the main raw materials to produce various plastic products through physical or chemical methods. Its core is to endow plastic materials with specific shapes and functions through molding technology, and it is widely used in packaging, construction, electronics, automobiles, and other fields.
[0003] Patent CN222589188U discloses a surface treatment device for processing plastic retainers. The device includes a mounting frame, with a motor fixedly connected to the top left side of the frame. A tensioning assembly is fixedly connected to the motor's output end. This invention uses the tensioning assembly to fix the plastic retainer. The motor drives the plastic retainer to rotate, and the grinding assembly moves upward, grinding the surface of the plastic retainer. Plastic dust is generated on the surface of the retainer. A fan is activated, and the fan, in conjunction with an air pipe and an arc-shaped dust suction plate, transports the plastic dust inside the arc-shaped dust suction plate into the collection box. When the airflow and plastic dust pass through a filter frame, the airflow passes through, and the plastic dust is filtered by the filter frame, preventing the plastic dust from spreading. This provides advantages in safety and environmental protection. The plastic dust on the top and sides of the grinding disc is sucked up and collected, preventing it from falling onto surrounding objects and being inhaled by workers, thus improving the safety of the surface treatment equipment.
[0004] Although the device has many beneficial effects, the following problems still exist: Although the surface treatment equipment improves the safety of its use, some impurities that are difficult to clean are easily attached to the surface of the finished plastic products after they are made. If these impurities are not treated in time, they can affect the appearance of the products. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figures 1-4 This utility model provides a technical solution:
[0027] An automatic material feeding machine for plastic processing includes a support frame 1, an upper suction box 3 fixedly connected to the top of the support frame 1, a first suction pump 2 fixedly installed on the top of the upper suction box 3, a connecting plate 18 provided inside the support frame 1, a lower suction box 4 fixedly connected to the outer surface of the connecting plate 18, and a second suction pump 11 fixedly installed at the bottom of the lower suction box 4. Both the upper suction box 3 and the lower suction box 4 are hollow inside. The machine also includes:
[0028] A cleaning component, located on the outer surface of the connecting plate 18 and the support frame 1, is used to clean the surface of the finished plastic product;
[0029] The adjustment component, located on the outer surface of the support frame 1, is used to adjust the height of the lower scraper 5. The upper suction box 3 generates a strong negative pressure through the first suction pump 2 to adsorb impurities on the upper outer surface of the plastic product into the upper suction box 3. The lower suction box 4 operates synchronously through the second suction pump 11 to adsorb impurities on the upper outer surface of the plastic product into the lower suction box 4.
[0030] Furthermore, the cleaning components include a lower scraper 5, an upper scraper 15, springs 19, and a mounting block 20. The mounting block 20 is fixedly connected to the top inner wall of the support frame 1. Multiple equidistantly distributed springs 19 are fixedly connected to the outer surface of the mounting block 20. The other end of the multiple springs 19 is elastically connected to the upper scraper 15. The top of the lower suction box 4 is fixedly connected to the lower scraper 5, which is E-shaped. The upper scraper 15 is supported by the array of springs 19 and maintains flexible contact with the upper surface of the finished product. The E-shaped lower scraper 5 is in clearance fit with the conveyor belt 8, and its edge contacts the finished product when it passes through, peeling off stubborn impurities from the outer surface.
[0031] Furthermore, two fixed blocks are fixedly connected to both sides of the support frame 1, and two support blocks 14 are fixedly connected between the two fixed blocks. Two bearing seats are fixedly connected to both sides of the support frame 1, and a rotating shaft is rotatably connected between the two bearing seats. Two conveyor wheels 6 are fixedly connected to the outer surfaces of the two rotating shafts. A conveyor belt 8 is sleeved between the two conveyor wheels 6 on the same side. A drive motor 7 is fixedly installed on the outer surface of one of the bearing seats. The output end of the drive motor 7 is fixedly connected to the corresponding rotating shaft. The drive motor 7 drives the rotating shaft to rotate, thereby driving the two conveyor wheels 6 to drive the conveyor belt 8 to convey the plastic finished product during the rotation process.
[0032] Furthermore, limit grooves 13 are provided on both outer surfaces of the support frame 1, and movable columns 10 are fixedly connected to both outer surfaces of the connecting plate 18. The two movable columns 10 are located inside the corresponding limit grooves 13 and are slidably connected, driving the connecting plate 18 to slide vertically within the limit grooves 13.
[0033] Furthermore, the adjustment assembly includes a push cylinder 9, connecting rods 12, and rollers 21. The push cylinder 9 is fixedly installed on the inner wall of the support frame 1. One end of two connecting rods 12 is rotatably connected inside the support frame 1. The two connecting rods 12 are arranged in an X shape and are rotatably connected. The output end of the push cylinder 9 is fixedly connected to the connection point of the two connecting rods 12. The other end of each of the two connecting rods 12 is rotatably connected to a roller 21. The two rollers 21 are rolled and fit against the inner wall of the support frame 1. The push cylinder 9 drives the two X-shaped connecting rods 12 to extend and retract, thereby adjusting the height of the lower scraper 5. The rolling friction design between the rollers 21 and the inner wall of the support frame 1 reduces the sliding resistance.
[0034] Furthermore, the outer surface of the support frame 1 is provided with scale lines 16, and the outer surface of the connecting plate 18 is fixedly connected with an indicator block 17. The indicator block 17 is movably connected to the outer surface of the scale lines 16. The operator can quickly set the cleaning height by real-time alignment of the indicator block 17 with the scale lines 16, which can adapt to plastic products of different thicknesses.
[0035] Working principle: When the operator needs to use the automatic suction box for plastic processing, the upper suction box 3 generates a strong negative pressure through the first suction pump 2, which adsorbs impurities on the upper outer surface of the plastic product into the upper suction box 3. The lower suction box 4 operates synchronously through the second suction pump 11, adsorbing impurities on the upper outer surface of the plastic product into the lower suction box 4. The upper scraper 15 is supported by an array of springs 19, maintaining flexible contact with the upper surface of the product. The E-shaped lower scraper 5 is in clearance fit with the conveyor belt 8, and its edge contacts the product as it passes through, peeling off stubborn impurities on the outer surface. When the drive motor 7 drives the rotating shaft to rotate, it drives the two conveyor wheels 6 to drive the conveyor belt 8 to convey the plastic product during the rotation process. The cylinder 9 drives the two X-shaped connecting rods 12 to extend and retract, causing the connecting plate 18 to slide vertically in the limiting groove 13, realizing the height adjustment of the lower scraper 5. The rolling friction design between the roller 21 and the inner wall of the support frame 1 reduces the sliding resistance. The operator can quickly set the cleaning height by aligning the indicator block 17 with the scale line 16 in real time, adapting to plastic products of different thicknesses.
