Description

Technical Field

[0001] The present invention relates to the technical field of polymer foaming, and particularly to a polymer prepolymer method foaming device. Background Art

[0002] When people or equipment travel in the wild, they often face various natural obstacles. Quickly and effectively breaking through various obstacles and quickly laying temporary roads in the wild are the premise and key to ensuring the successful progress of people or equipment. For the traditional removal of some obstacles that impede passage in the wild and the rapid laying of temporary passage roads, mainly methods such as bypassing and removing are adopted. However, this method consumes a large amount of physical strength of personnel, takes a long time, has low efficiency, and it is easy to form new obstacles again during the removal process. At present, research has proposed a flexible method to overcome the above problems, that is, by filling, covering, wrapping, and blocking the above obstacles with high-strength foam or foamed polymers, a safe passage can be quickly laid to facilitate the rapid passage of people and equipment. One of the key technologies to achieve this method is to use a good foaming agent so that when it is mixed with the polymer and sprayed at the obstacle, it can quickly foam and expand to fill, cover, wrap, block, etc. the obstacle.

[0003] The polymer foaming operation is to make a polymer foaming raw material into a porous polymer foaming material with a pore diameter less than one hundred micrometers and a pore density greater than a certain amount within a suitable pressure and temperature. However, due to the difficulty of forming bubbles in the existing technology for the foaming raw material at a suitable air pressure and temperature, it is even more difficult to control the air pressure and temperature inside the foaming material, resulting in difficulty in preparing thick block polymer microporous foaming materials (such as large flat plates and in-mold foaming), poor applicability, high requirements for precision control and equipment (such as injection foaming), and it is difficult to guarantee the quality of the finished product.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] (1). For the polymer prepolymer method foaming equipment, the box body formed by docking the prepolymer mechanisms on both sides with the half box is used to carry the polymer foaming raw materials. The temperature and pressure inside the box body are sensed by sensors, and the temperature and pressure inside the box body are adjusted to be appropriate by the second heater and the pressure regulator. When the raw material foaming is completed, the motor is started to make the half box in the middle rotate towards the lower side, so that the polymer foaming material loses its bearing capacity and automatically discharges the material. Through the design of inserting the plug board into the slot, when the raw material is forming inside the box body, the raw material close to the plug board part may bulge. During the process of the half box rotating and discharging the material, through its relative rotation, the plug board will gradually enter the slot. At this time, the blade two and blade one on the cutting board will cut the bulging material to ensure the regularity of the material produced by the foaming equipment.

[0016] (2). For the polymer prepolymer method foaming equipment, through the insertion design of the plug board and the slot, it can assist the half box to dock to form a unified box body during the process of carrying the raw material. During the discharging process, the flexibility of the plug board can adapt to the relative rotation of the half box to ensure the normal operation of discharging. In addition, the movement of the plug board during the discharging process can also assist in regularizing the material and improve the working flexibility of the equipment.

[0017] (3) This polymer prepolymer method foaming equipment forms a double-sided prepolymer within the box formed by docking the half-boxes. The formation of the double-sided prepolymer only requires detecting the temperature and pressure in the outer space of the raw materials, facilitating the shaping of the materials. After the prepolymer is formed, the half-box is rotated to convey it to the joining mechanism through the middle mechanism for constant-temperature collection. When high-thickness materials are needed, prepolymers can be formed again and then fed. The prepolymers formed twice are stacked in the joining mechanism, and the second-formed prepolymer, which has not completely solidified, joins with the first-formed prepolymer, enabling the sequential accumulation of high-thickness materials. If large-area materials need to be formed, only by controlling the moving column to move the bottom frame so that the square hollow is aligned with the dropping hole, and similarly making the dropped materials join together, simplifies the operation of synthesizing high-tech materials and increases the variety of products produced by the equipment.

[0018] (4) In this polymer prepolymer method foaming equipment, a sensor is installed at the lower end of the telescopic column to sense the height of the stacked materials, enabling the adjustment of the lower position according to the height of the materials. Additionally, through the positioning of the telescopic column and the moving column, and the guiding ability in the vertical state of the half-box, the materials formed at the prepolymer mechanism can fall more accurately to the position where the lower backing plate is located, improving the docking accuracy of the equipment.

[0019] (5) In this polymer prepolymer method foaming equipment, each time when discharging materials, the half-box is rotated 180 degrees by the motor, and then the mixing box is driven to move by the electric control sliding column. When the discharging port moves out of the range of the blocking plate to the right, the raw materials inside the mixing box will gradually fall in a strip shape into the box formed by the docking of the half-boxes. During the rightward movement and return of the mixing box, a double-layer raw material laying is just formed, improving the forming speed of the prepolymer.

[0020] (6) In this polymer prepolymer method foaming equipment, the cover plate and the mixing box are integrally connected through the connecting column. In this way, during the discharging process at the discharging port, the cover plate does not hinder the discharging of the equipment. Additionally, when the mixing box returns to its position, the cover plate and the blocking plate are docked, and at the same time, the sealing plate one and the sealing plate two dock the box formed by the half-boxes, making the upper side and the left and right sides of the box in a closed state. The front and rear sides of the box are sealed by the partition plates, ensuring that the box is in a closed state during the foaming process without the need for repeated closing operations, simplifying the operation of prepolymer formation.

[0021] (7) In the process of the equipment working, the prepolymer mechanism on the right rotates counterclockwise, and the prepolymer mechanism on the left rotates clockwise, so as to adapt to the connection with the first sealing plate and the second sealing plate. When the prepolymer mechanism operates, it does not interfere with the feeding mechanism. In addition, during the process of pressurizing the enclosed space formed by the box body, the connection of the first sealing plate and the second sealing plate also avoids the possibility of its outward movement to expand the space, improving the adaptability between the equipment mechanisms and making the working process of the equipment faster and smoother.

The sliding column 515 can drive the mixing box 510 to move left and right along the track set by the column 514.

[0047] Working principle:

[0048] Step 1: The box formed by the docking of the two pre-polymerization mechanisms 4 on both sides with the half box 403 is used to carry the polymer foaming raw materials. The temperature and pressure inside the box are sensed by the sensor 404. The temperature and pressure inside the box are adjusted to be appropriate through the heater II 508 and the pressure regulator 509. When the raw material foaming is completed, the motor 401 is started to make the middle half box 403 rotate in the direction close to the lower side, so that the polymer foaming material loses its bearing capacity and automatically discharges. Through the design of inserting the insertion plate 410 into the slot 405, when the raw material is forming inside the box, the raw material near the insertion plate 410 may protrude. During the process of the half box 403 rotating and discharging, the relative rotation will make the insertion plate 410 gradually enter the slot 405. At this time, the blade II 409 and the blade I 408 on the cutting plate 407 will cut the protruding material to ensure the regularity of the material produced by the foaming equipment.

[0049] Step 2: Through the insertion design of the insertion plate 410 and the slot 405, it can assist the half box 403 to dock to form a unified box during the process of carrying the raw materials. During the discharging process, the flexibility of the insertion plate 410 can adapt to the relative rotation of the half box 403 to ensure the normal operation of discharging. In addition, the movement of the insertion plate 410 during the discharging process can also assist in regularizing the material and improve the working flexibility of the equipment.

[0050] Step 3: A double-sided prepolymer is formed inside the box formed by docking the half box 403. The formation of the double-sided prepolymer only needs to detect the temperature and pressure in the outer space of the raw material, which is convenient for the forming of the material. After the prepolymer is formed, the half box 403 is rotated and transported to the joint mechanism 2 through the middle mechanism 3 for constant-temperature collection. When high-thickness materials are needed, the prepolymer can be formed again and then discharged, so that the prepolymers formed twice are stacked in the joint mechanism 2, and the second-formed prepolymer has not completely solidified and is jointed with the first-formed prepolymer, so that high-thickness materials can be successively accumulated. If large-area materials need to be formed, only by controlling the moving column 204 to move the bottom frame 201 so that its square hollow is aligned with the falling hole 302, and similarly making the falling materials jointed, the operation of synthesizing high-tech materials is simplified and the output types of the equipment are increased.

[0051] Step 4: An inductor is installed at the lower end of the telescopic column 303 to sense the height of the stacked materials, so as to be able to adjust the lower position according to the height of the materials. In addition, through the positioning of the telescopic column 303 and the moving column 204, and the guiding ability of the half box 403 in the vertical state, the materials formed at the prepolymerization mechanism 4 can fall more accurately to the position of the lower cushion plate 202, improving the docking accuracy of the equipment.

[0052] Step 5: Each time when discharging, drive the half box 403 to turn 180 degrees by the motor 401. Then drive the mixing box 510 to move by the electric control slide column 515. When the discharge port 511 moves out of the range of the blocking plate 501 to the right, the raw materials inside the mixing box 510 will gradually fall in a strip shape into the box formed by docking with the half box 403. During the process of the mixing box 510 moving to the right and then returning to its original position, a double-layer raw material laying is just formed, which improves the speed of prepolymer forming.

[0053] Step 6: Integrally connect the cover plate 504 and the mixing box 510 through the connecting column 513. In this way, during the process of discharging through the discharge port 511, the cover plate 504 will not hinder the equipment from discharging. In addition, when the mixing box 510 returns to its original position, the cover plate 504 and the blocking plate 501 are docked, and at the same time, the sealing plate one 503 and the sealing plate two 507 are docked with the box formed by the half box 403, so that the upper side and the left and right sides of the box are all in a closed state. The front and rear sides of the box are sealed by the partition plate 307, so as to ensure that the box is in a closed state during the foaming process without the need for re-closure operation, which simplifies the operation of prepolymer forming.

[0054] Step 7: During the operation of the equipment, the prepolymer mechanism 4 on the right rotates counterclockwise, and the prepolymer mechanism 4 on the left rotates clockwise, so as to adapt to the connection with the sealing plate one 503 and the sealing plate two 507. When the prepolymer mechanism 4 operates, it does not interfere with the feeding mechanism 5. In addition, during the process of pressurizing the closed space formed by the box, the connection of the sealing plate one 503 and the sealing plate two 507 also avoids the possibility of their outward movement to expand the space, improves the adaptability between the equipment mechanisms, and makes the working process of the equipment faster and smoother.
