Description

Technical Field

[0001] The invention relates to the technical field of plastic tableware processing, in particular to a plastic tableware injection molding and trimming device for recycling plastic waste. Background Art

[0002] After the plastic tableware is injection molded, a cross-section gate is generally left at the bottom, and a circle of waste material is left at the mouth of the tableware. At this time, the waste material that is easy to tear off is generally removed manually during the plastic tableware sorting process. However, after removing the circle of waste material, a circle of sharp burrs is left at the cup mouth of the plastic tableware. According to the different calibers of the produced plastic tableware, the position of the burrs also has some deviations. It is necessary to adjust the position of the scraper to achieve burr processing for plastic tableware of different calibers. Frequent shutdowns to adjust the scraper position not only consume a lot of manpower and material resources, but also increase the maintenance cost of the machinery. In addition, the burrs are directly scraped off by a cutter. When the burr hardness is high, it is not easy for the cutter to cut between the burr and the plastic tableware. Generally, in order to avoid damaging the cutter, the scraping rate is reduced to ensure the service life of the cutter. However, reducing the scraping rate will lead to low trimming efficiency and low production efficiency.

[0003] Chinese patent CN117754786A, authorized and announced on March 26, 2024, discloses a plastic tableware injection molding trimming device for recycling plastic waste, which includes a trimming knife and a beautifying unit. The beautifying unit is connected to the trimming knife. The present invention facilitates the cutting edge to stick to the inclined outer wall of the plastic wide-mouth cup by rotating the trimming knife, thereby adapting to the treatment of burrs at corresponding positions on plastic wide-mouth cups of different calibers, greatly expanding the scope of application of the device. By heating the trimming knife, the temperature of the trimming knife is increased, which facilitates the trimming knife to scrape off the burrs. The heating of the trimming knife facilitates the trimming knife to scrape off the burrs, and the burrs scraped off by the trimming knife are blown away from the cutting edge, which is conducive to automatic control. In the above application documents, when the equipment starts working, because the plastic cup is relatively light, the rotation of the blade easily causes the plastic cup to deviate, resulting in incomplete trimming, thereby affecting work efficiency.

The electric telescopic annular cutting blade 300 is set to cut off the excess waste material on the entire outer ring of the plastic cup 500, thereby more completely removing the burrs. The bottom of the electric telescopic annular cutting blade 300 is fixedly connected to a disconnecting assembly 1000, and the top of the rear side of the processing table 100 is movably connected to a discharge assembly 1100.The two sides of the processing table 100 are fixedly connected with fixed blocks 901, and the inner surface of the fixed block 901 is provided with a slide groove 902. The slide groove 902 is provided so that the L-shaped slider 904 slides along the direction of the slide groove 902. The bottom of the slide groove 902 is fixedly connected with an electric telescopic rod 903, and the top of the electric telescopic rod 903 is fixedly connected with the L-shaped slider 904. The inner side of the L-shaped slider 904 is rotatably connected to the support rod 905 through the rotating shaft 906. The interior of the fixed block 901 is slidably connected with a triangular slider 907. The rear side of the triangular slider 907 is fixedly connected to a push block 908. The rear side of the push block 908 is movably connected to a hydraulic block 910. The hydraulic block 910 and the push block 908 are connected. A spring 909 is fixedly connected between the two blocks. The spring 909 is provided so that the power of the push block 908 moving is converted into the elastic potential energy of the spring 909. The bottom of the hydraulic block 910 is fixedly connected to the fixed block 901 through the L-shaped bracket 911. The hydraulic block 910 is movably connected to the arc-shaped push block 917 through a transmission member. The transmission member includes a hose 912, a hydraulic block 913, a push block 914, a hose 915, and an arc-shaped hydraulic block 916. One end of the hose 912 is fixedly connected to the top of the hydraulic block 913, and the other end of the hose 912 is fixedly connected to the bottom of the hydraulic block 910. The rear side of the hydraulic block 913 is fixedly connected to the front side of the L-shaped slider 904. The hydraulic block The front side of the second hydraulic block 913 is movably connected with a push block 914, the right side of the push block 914 is fixedly connected to the side of the support rod 905, the interior of the hydraulic block 913 is fixedly connected to the arc hydraulic block 916 through the hose 915, the bottom of the arc hydraulic block 916 is fixedly connected to the support rod 905, and the side of the arc hydraulic block 916 is movably connected with an arc push block 917. There are two fixed blocks 901, two electric telescopic rods 903, two L-shaped sliders 904, two support rods 905, two triangular sliders 907, two push blocks 908, two springs 909, and two hydraulic blocks 910. There are two L-shaped brackets 911, two hoses 912, two hydraulic blocks 913, two push blocks 914, two hoses 915, two curved hydraulic blocks 916, and two curved push blocks 917. The curved push blocks 917 are positioned so that before the trimming process begins, they push outward to secure the sides of the plastic cup 500. Simultaneously, as the electric telescopic ring-shaped cutting blade 300 moves downward to cut, the sides and bottoms of the plastic cup 500 are supported by the curved push blocks 917, allowing the entire rim to be cut off. This completely removes burrs from the rim of the plastic cup 500 and improves equipment efficiency.

[0021] When the device starts working, the electric telescopic rod 903 is started, so that the L-shaped slider 904 is pushed upward by the electric telescopic rod 903, so that the triangular slider 907 moves outward, so that the push block 1 908 moves outward, so that the internal pressure of the hydraulic block 1 910 increases, and the internal pressure of the hydraulic block 1 910 is transmitted to the inside of the hydraulic block 2 913 through the hose 1 912, so that the internal pressure of the hydraulic block 2 913 increases, so that the push block 2 914 is pushed outward, and the support rod 905 is rotated inward by 90 degrees, so that the arc-shaped hydraulic block 916 is rotated by 90 degrees to The outer side of the plastic cup 500 is in contact. At this time, the excess pressure inside the hydraulic block 2 913 is transmitted to the inside of the arc-shaped hydraulic block 916 through the hose 2 915, which increases the internal pressure of the arc-shaped hydraulic block 916 and pushes the arc-shaped push block 917 outward, thereby fixing the side of the plastic cup 500. At the same time, when the electric telescopic annular cutting knife 300 moves downward for cutting, the bottom of the side of the plastic cup 500 is supported by the arc-shaped push block 917, so that the entire circle of the flash is cut off, thereby completely removing the burrs on the rim of the plastic cup 500 and improving the working efficiency of the equipment.

[0023] During use, based on Example 1, when the L-shaped slider 904 continues to move upward, the push block three 1001 moves upward, the internal pressure of the hydraulic block three 1002 increases, and the internal pressure of the left hydraulic block three 1002 is transmitted to the front hydraulic block four 1006 through the hose three 1004, so that the internal pressure of the front hydraulic block four 1006 increases. At the same time, the internal pressure of the right hydraulic block three 1002 is transmitted to the rear hydraulic block four 1006 through the hose four 1005, so that the internal pressure of the rear hydraulic block four 1006 increases, and the push block four 1007 is pushed downward, so that the vertical cutting knife 1008 is pushed downward to contact the gap between the two arc-shaped hydraulic blocks 916, so that the entire circle of waste cut off is disconnected, so that the waste can fall, making it easier for the staff to clean up the waste.
