Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of paper pulp molding, in particular to a device for reducing the accumulation of pulp in a pulp suction mold of a paper pulp molding reciprocating machine. Background Art
[0002] After the pulp-molding reciprocating machine sucks the pulp from the pulp box, it moves upward from the bottom of the pulp box to close the hot pressing concave mold. The pulp in the pulp box will flow from the suction mold to the pulp box; the suction mold travel time is only 3-4 seconds, resulting in the excess pulp not flowing out completely, all of which are accumulated on the suction mold screen frame and close the hot pressing concave mold. The pulp is dried at high temperature to form dry pulp, which falls into the pulp pool. During the molding process of the suction mold, the dry pulp enters the product to form a dark color, resulting in a low product yield; this patent will increase the height of the screen frame and make the suction mold frame into a slope to reduce the pulp flowing down from the product. At the same time, the flowing pulp will quickly enter the pulp pool, reducing the dry pulp formed by the hot pressing concave mold, reducing the dark spots of the product, and thus improving the product yield. Pulp molding is a three-dimensional papermaking technology. It uses waste paper as raw material and shapes paper products of a certain shape by a special mold on a molding machine. It has four major advantages: the raw materials are waste paper, including cardboard, waste carton paper, waste white-edge paper, etc., which are widely available; its production process is completed by pulping, adsorption molding, drying and shaping, etc., which is harmless to the environment; it can be recycled and reused; its volume is smaller than that of foamed plastics, it can be overlapped, and it is convenient for transportation. In addition to making lunch boxes and tableware, pulp molding is more used for industrial cushioning packaging, and it has developed very rapidly.
[0003] The existing reciprocating machine slurry suction mold screen frame is convex, and the protrusion is small, which cannot better prevent the slurry from flowing out. At the same time, the slurry suction mold frame is flat, which is not conducive to the slurry flowing out to quickly return to the slurry box; the slurry will be dried to form dry slurry after the hot pressing die is closed, and it will form a dark color when it falls into the slurry pool, resulting in an increase in the dark color of the product and a decrease in the yield. A device for reducing the accumulation of slurry in the slurry suction mold of a pulp molding reciprocating machine is now invented to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0021] Example 1
[0022] See also Figures 1 to 4 The utility model provides a technical solution: a device for reducing the accumulation of pulp in the pulp suction mold of a pulp molding reciprocating machine, comprising a pulp box 1, a pulp suction film base 2, a hydraulic rod 3, a pulp suction mold frame 4, a screen pressing frame 5, a space 6 for avoiding the screen pressing frame, a hot pressing concave mold 7, a waste edge 8, a positioning block 9 and a slope 10 of the pulp suction mold frame, the length and width of the hot pressing concave mold 7 are both smaller than the length and width of the pulp box 1, the position of the waste edge 8 corresponds to the position of the space 6 for avoiding the screen pressing frame, the position of the hot pressing concave mold 7 corresponds to the position of the pulp suction mold frame 4, the position of the hot pressing concave mold 7 is located above the pulp suction mold frame 4, the bottom of the pulp box 1 is equipped with a hydraulic rod 3, and the inner bottom wall of the pulp box 1 is equipped with a pulp suction film bottom Seat 2, a slurry suction mold frame 4 is installed on the top of the slurry suction film base 2, and the position of the slurry suction mold frame 4 is located inside the slurry box 1. The length and width of the slurry suction mold frame 4 are smaller than the length and width of the slurry suction film base 2. A screen pressing frame 5 and a positioning block 9 are respectively installed on the top of the slurry suction mold frame 4. The screen pressing frame 5 is raised by 5mm to prevent some excess slurry from flowing out. A slurry suction mold frame slope 10 is provided on the inclined surface of the slurry suction mold frame 4. The inclination gradient of the slurry suction mold frame slope 10 is 17 degrees. The position of the positioning block 9 corresponds to the position of the slurry suction mold frame slope 10. The slope of the slurry suction mold frame slope 10 is set to a slope of 17°. A screen pressing frame avoidance space 6 is provided at the bottom of the hot pressing die 7.
[0023] When in use, the slurry suction mold screen frame 5 is raised by 5mm, the hot pressing die 7 is avoided by 5mm, and at the same time, the area outside the screen frame 5 on the slurry suction mold frame 4 is made into a 17° slope; the slurry suction mold frame 4 rises after washing the slurry, and the raised screen frame 5 prevents a part of the excess slurry from flowing out. At the same time, the inclined slurry suction mold frame 4 is more conducive to the flow of slurry, so that the slurry flows into the slurry box 1 faster. When the slurry suction mold frame 4 and the hot pressing die 7 are molded together, the raised screen frame 5 is embedded in the avoidance screen frame space 6 on the hot pressing die 7, so that when the hot pressing die 7 and the slurry suction mold frame 4 are demoulded, the slurry blown off by the compressed air of the hot pressing die 7 Confined in the slurry absorption mold frame 4, the inferior slurry will become a part of the waste edge 8 of the product through the extrusion of the hot pressing die 7 and the slurry absorption mold frame 4, thereby preventing the hot pressing die 7 from compressing the air to blow away the slurry and preventing the waste slurry from becoming dark; thereby improving the product yield. The patent will increase the height of the screen pressing frame 5 and make the slurry absorption mold frame 4 into a slope to reduce the slurry flowing down from the product. At the same time, the flowing slurry will quickly enter the slurry pool to reduce the slurry that is dried by the hot pressing die 7 to form dry slurry. Physical methods are used without the need for additional energy consumption to reduce the formation of dry slurry, thereby reducing the dark color of the product and improving the product yield.
