Working principle:
The first step, the two-side prepolymer mechanism 4 is used for bearing polymer foaming raw materials to a box body formed by abutting the half box 403, the temperature and the pressure inside the box body are sensed by the sensor 404, the temperature and the pressure inside the box body are adjusted by the heater II 508 and the pressurizer 509, after the foaming of the raw materials is completed, the motor 401 is started to enable the half box 403 in the middle to rotate towards the lower side, so that the polymer foaming materials lose bearing capacity and are automatically fed, the raw materials near the position of the inserting plate 410 possibly bulge when the raw materials are inserted into the inserting groove 405 through the design that the inserting plate 410 is inserted into the inserting groove 405, the inserting plate 410 gradually enters the inserting groove 405 through the relative rotation of the inserting plate 403 in the process of feeding through the rotation of the half box 403, and at the moment, the cutter II 409 and the cutter I408 on the cutting plate 407 cut the bulged materials, so that the regularity of the materials produced by the foaming equipment is ensured.
The second step is that through the design of inserting the plugboard 410 and the slot 405, the half box 403 can be assisted to be butted to form a unified box body in the process of bearing raw materials, the expansion performance of the plugboard 410 can adapt to the relative rotation of the half box 403 in the process of unloading, the normal operation of unloading is ensured, in addition, the movement of the plugboard 410 in the process of unloading can assist in regulating materials, and the working flexibility of equipment is improved.
And thirdly, forming a double-sided prepolymer in a box body formed by a butt joint half box 403, wherein the double-sided prepolymer is formed by detecting the temperature and the pressure of the outer space of the raw materials, the forming of the materials is convenient, after the prepolymer is formed, the prepolymer is conveyed to a joint mechanism 2 through a middle layer mechanism 3 by rotating the half box 403, and is collected at constant temperature, when the materials with high thickness are needed, the prepolymer formed twice can be stacked in the joint mechanism 2 by forming the prepolymer again and then blanking, and the prepolymer formed for the second time is not completely solidified and is combined with the prepolymer formed for the first time, so that the materials with high thickness can be formed in sequence, and if the materials with large area are needed to be formed, the moving column 204 is controlled to enable the square hollow of the bottom frame 201 to move to be opposite to the position of the falling hole 302, and the falling materials are jointed in the same way, so that the operation of synthesizing the materials with high technology is simplified, and the output types of equipment are improved.
And fourthly, the lower end of the telescopic column 303 is provided with an inductor, and the height of the stacked materials is sensed, so that the height of the materials can be adapted to the adjustment of the lower end position, and in addition, the materials formed at the position of the prepolymer mechanism 4 can accurately fall to the position of the lower base plate 202 through the positioning of the telescopic column 303 and the movable column 204 and the guiding capability of the half box 403 in the vertical state, so that the butting accuracy of equipment is improved.
And fifthly, during each discharging, the motor 401 drives the half box 403 to turn over for one hundred eighty degrees, then the electric control slide column 515 drives the mixing box 510 to move, after the discharging opening 511 moves out of the range of the blocking plate 501 to the right, raw materials in the mixing box 510 gradually take the shape of a strip and fall into a box body formed by butt joint of the half box 403, and the double-layer raw materials are just paved during the right movement and return of the mixing box 510, so that the forming speed of the prepolymer is improved.
And in the sixth step, the cover plate 504 and the mixing box 510 are integrally connected through the connecting column 513, so that the cover plate 504 does not obstruct equipment blanking in the blanking process of the blanking opening 511, in addition, the cover plate 504 and the blocking plate 501 are in butt joint while the mixing box 510 returns, meanwhile, the first sealing plate 503 and the second sealing plate 507 are in butt joint with the box body formed by the half box 403, the upper side and the left side and the right side of the box body are in a closed state, and the front side and the rear side of the box body are sealed through the partition 307, so that the box body is in a closed state in the foaming process, the sealing operation is not needed again, and the operation of prepolymer forming is simplified.
Seventh, in the working process of the equipment, the pre-polymer mechanism 4 on the right side rotates anticlockwise, and the pre-polymer mechanism 4 on the left side rotates clockwise, so that the connection between the pre-polymer mechanism 4 and the first sealing plate 503 and the second sealing plate 507 is adapted, the pre-polymer mechanism 4 is not mutually blocked by the feeding mechanism 5 when in operation, in the pressurizing process of the closed space formed by the box body, the connection between the first sealing plate 503 and the second sealing plate 507 simultaneously avoids the possibility of outward movement of the sealing plate to expand the space, the adaptability between the equipment mechanisms is improved, and the working process of the equipment is faster and smoother.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
