Description

Technical Field

[0001] This invention relates to the field of sponge foaming technology, specifically to a green sponge foaming device and process based on recycled waste materials. Background Technology

[0002] Traditional sponge foaming devices typically require manual pushing of a trolley to the bottom of the foaming box, followed by manual closing of the foaming box and adjustment of the distance between the bottom wall of the foaming box and the top wall of the trolley. After foaming is complete, the foaming box must be opened manually, and the sponge must be manually detached from the inner wall of the foaming box. Finally, the trolley must be manually pushed again to transfer the sponge.

[0003] In the above operation process, the steps of moving the trolley, opening and closing the foaming box, and detaching the sponge are all completed manually one by one. Not only are the operation steps cumbersome and labor-intensive, but the overall work efficiency is also low. At the same time, the personnel need to be close to the foaming device for a long time throughout the process, which makes them susceptible to the gas generated during the foaming process, posing certain safety and health hazards. Summary of the Invention

To solve these problems, this invention employs the following technical solution: A green sponge foaming device based on recycled waste materials includes a base, a foaming box, and an intelligent transport vehicle. The foaming box is fixed to the top wall of the base and has a foaming cavity. A sliding door is slidably connected to the foaming box. The intelligent transport vehicle is equipped with a lifting support mechanism. The foaming box is equipped with a sponge release mechanism and a door drive mechanism, which are connected to the sliding door.

[0005] Optionally, the lifting support mechanism includes a movable pallet, which is slidably connected to the intelligent transport vehicle. The movable pallet is connected to the intelligent transport vehicle through an elastic element. A lock head and an inclined transmission block are fixedly connected to the movable pallet.

An inclined transmission plate is fixedly connected to the foam box. A cylinder is connected to the intelligent transport vehicle.

[0006] Optionally, the door drive mechanism includes an L-shaped locking rod, a pull rope, a steering wheel, and a transmission seat. The L-shaped locking rod and the transmission seat are slidably connected to the foaming box. Both the L-shaped locking rod and the transmission seat extend to the bottom of the foaming box. A limit groove is provided on the transmission seat. A limit strip is fixedly connected to the L-shaped locking rod. Two or more steering wheels are rotatably connected to the foaming box. One end of the pull rope is fixedly connected to the transmission seat, and the other end of the pull rope is fixedly connected to the sliding door after passing through the reversal of all the steering wheels.

[0007] Optionally, the sponge release mechanism includes a separation toothed plate, a gear, and a transmission tooth.

The intelligent transport vehicle moves to the bottom of the foam box, so that the lifting support mechanism moves up and abuts against the bottom wall of the foam box. Then, the door drive mechanism drives the sliding door to move down, so that the sliding door abuts against the lifting support mechanism. The foaming material is poured into the foaming chamber to carry out a foaming reaction. The foaming material expands and forms a sponge in the foaming chamber. After foaming is completed, the sliding door is driven upward by the door drive mechanism, and the sponge is pushed by the sponge release mechanism to release the sponge from the adhesion state with the inner wall of the foaming chamber. The sponge is then supported by the lifting support mechanism, which then descends and releases its contact with the bottom wall of the foaming box, so that the intelligent transport vehicle can move. The movement of the intelligent transport vehicle realizes the transportation of the sponge.

[0014] The present invention has the following beneficial effects: This application achieves continuous automatic execution of the foaming, opening and closing, demolding and transportation processes through the coordinated operation of intelligent transport vehicles, door drive mechanisms and sponge release mechanisms. This improves production efficiency and saves labor, while reducing the time personnel spend near the foaming box, thereby reducing the adverse effects of gas and heat on personnel during the foaming process and improving production safety.

[0021] like Figures 2-6 As shown, a green sponge foaming device based on recycled waste materials includes a base 1, a foaming box 2, and an intelligent transport vehicle 10. The foaming box 2 is fixed to the top wall of the base 1, and a foaming cavity 21 is opened on the foaming box 2. A sliding door 3 is slidably connected to the foaming box 2. The intelligent transport vehicle 10, the base 1, and the foaming box 2 are separate. The intelligent transport vehicle 10 can move independently. The intelligent transport vehicle 10 is equipped with a lifting support mechanism. The foaming box 2 is equipped with a sponge release mechanism and a door drive mechanism. The door drive mechanism is connected to the sliding door 3.

[0022] To enable remote control of the intelligent transport vehicle 10, the intelligent transport vehicle 10 is equipped with an intelligent control system.

[0023] Furthermore, the intelligent control system includes an existing wireless communication module, a main control processing module, a motion drive module, and a power management module. The wireless communication module is used to receive wireless control commands from an external control terminal and send operating status information. The main control processing module is used to parse and process the received control commands. The motion drive module is used to drive the intelligent transport vehicle 10 to achieve forward, backward, and turning movements. The power management module is used to provide stable power to each module and manage power consumption, thereby realizing wireless control and motion execution of the intelligent transport vehicle 10.

[0024] like Figure 7As shown, to achieve automatic lifting of the lifting support mechanism, based on the above scheme, the lifting support mechanism includes a movable support plate 11, which is slidably connected to the intelligent transport vehicle 10. The movable support plate 11 is connected to the intelligent transport vehicle 10 through an elastic element 12. A lock head 13 and an inclined transmission block 15 are fixedly connected to the movable support plate 11. A lock device 14 is embedded in the intelligent transport vehicle 10, and a lock cavity is opened on the lock device 14. A press-to-lock mechanism adapted to the lock head 13 is provided in the lock cavity. An inclined transmission plate 16 is fixedly connected to the foam box 2. A cylinder 17 is connected to the intelligent transport vehicle 10. The cylinder 17 can be directly set on the top wall of the transport vehicle 10 or on the bottom wall of the movable support plate 11. The lock head 13 can be interlocked by pressing it once on the press-to-lock mechanism, and can be unlocked by pressing it again. The structure is based on existing technology and is not limited or described here.

[0025] like Figures 4-6 As shown, to achieve automatic drive of the door drive mechanism, in a preferred embodiment, the door drive mechanism includes an L-shaped locking rod 6, a pull rope 7, a steering wheel 8, and a transmission seat 9. The L-shaped locking rod 6 and the transmission seat 9 are slidably connected to the foaming box 2, and both the L-shaped locking rod 6 and the transmission seat 9 extend to the bottom of the foaming box 2. A limiting groove 4 is formed on the transmission seat 9, and a limiting strip 5 is fixedly connected to the L-shaped locking rod 6. The limiting strip 5 can be inserted into the limiting groove 4. The length, width, and height of the limiting groove 4 are slightly larger than the limiting strip 5. Two or more steering wheels 8 are rotatably connected to the foaming box 2. In this invention, three steering wheels 8 are preferred. One end of the pull rope 7 is fixedly connected to the transmission seat 9, and the other end of the pull rope 7 is fixedly connected to the sliding door 3 after the reversal of all the steering wheels 8. The pull rope 7 is preferably a steel wire rope or nylon rope with wear-resistant, tensile-resistant, and non-aging properties.

[0026] like Figures 4-6 As shown, to achieve sponge detachment, in one optional configuration, the sponge detachment mechanism includes a separating toothed plate 18, a gear 19, and a transmission gear 20. The separating toothed plate 18 is slidably connected to the foaming box 2 and extends into the foaming cavity 21. The gear 19 is rotatably connected to the foaming box 2, and the transmission gear 20 is disposed on the transmission seat 9. The separating toothed plate 18 and the gear 19 mesh. Due to the presence of the gear 19, the movement directions of the separating toothed plate 18 and the transmission seat 9 are opposite.

[0027] It is worth noting that the top wall, side wall and bottom wall of the foaming cavity 21 and the foaming box 2 are all connected.

[0028] To increase the contact area between the separating toothed plate 18 and the sponge and improve the separation effect, the separating toothed plate 18 is L-shaped.

[0029] To allow the intelligent transport vehicle 10 to pass underneath the foam box 2, the foam box 2 is fixed to the top wall of the base 1 by a bracket. The number of brackets is not limited and is set according to the weight of the foam box 2.

[0030] To facilitate the movement of the intelligent transport vehicle 10 onto the base 1, the base 1 is provided with a ramp.

[0031] like Figure 1 As shown, a green sponge foaming process based on recycled waste materials, and a green sponge foaming device based on recycled waste materials, includes the following steps: Prepare the foaming raw materials, which include recycled polyols obtained by alcoholysis of waste polyurethane foam; A liner is laid on the lifting support mechanism, and the intelligent transport vehicle 10 is controlled to move to the top wall of the base 1. The intelligent transport vehicle 10 moves to the bottom of the foam box 2, so that the lifting support mechanism moves up and abuts against the bottom wall of the foam box 2. Then the door drive mechanism drives the sliding door 3 to move down, so that the sliding door 3 abuts against the lifting support mechanism. The foaming material is poured into the foaming chamber 21 to carry out a foaming reaction. The foaming material expands and forms a sponge in the foaming chamber 21. After foaming is completed, the sliding door 3 is driven upward by the door drive mechanism, and the sponge is pushed by the sponge release mechanism to release the sponge from the adhesion state with the inner wall of the foaming chamber 21. The sponge is supported by the lifting support mechanism, and then the lifting support mechanism descends and releases its contact with the bottom wall of the foaming box 2 so that the intelligent transport vehicle 10 can move. The movement of the intelligent transport vehicle 10 realizes the transportation of the sponge.

[0032] Implementation process: Prepare the foaming raw materials, which include recycled multi-element materials obtained by alcoholysis of waste polyurethane foam. Waste polyurethane foam is a thermoplastic. Reusing waste plastics can produce green sponges, which is in line with the concept of environmental protection.

[0033] Foaming raw materials also include isocyanates, foaming agents, catalysts, and foam levelers, among other materials.

[0034] A liner paper is laid on the top wall of the movable pallet 11. The liner paper can be kraft paper to prevent the sponge from sticking to the top wall of the movable pallet 11, which would make it difficult to separate later.

[0035] In the initial state, the self-locking mechanism in the lock head 13 and the lock device 14 is locked, the elastic element 12 is compressed, the transmission seat 9 is in the left extreme position, the separation tooth plate 18 and the transmission tooth 20 are both engaged with the gear 19, the limit strip 5 is inserted into the limit groove 4 to limit the transmission seat 9, the lower end of the vertical section of the L-shaped lock rod 6 extends to the bottom of the foam box 2, and the sliding door 3 is in the high position and in the open state.

[0036] The intelligent transport vehicle 10 moves along the ramp to the top wall of the base 1. The intelligent transport vehicle 10 then moves left to below the foaming box 2. After the inclined transmission block 15 and the inclined transmission plate 16 abut against each other, the inclined transmission plate 16 pushes the inclined transmission block 15 down a short distance, causing the lock head 13 to be pressed and unlocked on the self-locking mechanism. The intelligent transport vehicle 10 continues to move left, and the movable tray 11 moves upward under the elastic force of the elastic element 12 until the top wall of the movable tray 11 abuts against the bottom wall of the foaming box 2, preventing the subsequent leakage of foaming materials. The top wall of the movable support plate 11 pushes the vertical section of the L-shaped locking rod 6 upward, thereby causing the limiting strip 5 to move upward and disengage from the limiting groove 4. After the transmission seat 9 loses the limitation of the limiting strip 5, the sliding door 3 moves downward under its own gravity until the bottom wall of the sliding door 3 and the top wall of the movable support plate 11 come into contact. When the sliding door 3 moves downward, the transmission seat 9 is pulled to the right by the pull rope 7. The transmission seat 9 drives the gear 19 to rotate. The gear 19 drives the separation tooth plate 18 to move to the left. When the transmission tooth 20 disengages from the gear 19, the right wall of the separation tooth plate 18 and the inner wall of the foaming cavity 21 are almost flush.

[0037] The foaming material is poured into the foaming chamber 21 for foaming, and the foaming material forms a sponge after foaming.

[0038] Because the movable pallet 11 exerts pressure on the foaming box 2, there is a large friction between the movable pallet 11 and the foaming box 2. At this time, it is difficult to move the intelligent transport vehicle 10 by the power of the wheels. The piston rod of the control cylinder 17 extends. After the piston rod and the transmission seat 9 come into contact, the piston rod pushes the transmission seat 9 to the left. The transmission seat 9 pulls the sliding door 3 upward through the pull rope 7 to open, so that the subsequent sponge can be separated from the foaming cavity 21. Then the transmission gear 20 and the gear 19 mesh. The transmission gear 20 drives the separation tooth plate 18 to the right and enter the foaming cavity 21 through the gear 19. The separation tooth plate 18 pushes the sponge, so that the sponge adhering to the inner wall of the foaming cavity 21 is separated from the inner wall of the foaming cavity 21 and falls onto the top wall of the movable pallet 11.

[0039] When the transmission seat 9 moves to the left limit position, the piston rod continues to extend, thereby pushing the intelligent transport vehicle 10 to the right. After the inclined transmission block 15 and the inclined transmission plate 16 abut against each other, the inclined transmission block 15 is pushed down by the inclined transmission plate 16, thereby causing the movable support plate 11 and the lock head 13 to overcome the elastic force of the elastic element 12 and move down. The lock head 13 is inserted into the lock cavity of the lock device 14 and interlocks with the pressing self-locking mechanism. After the inclined transmission block 15 moves to the right of the inclined transmission plate 16, the movable support plate 11 and the lock head 13 rebound a short distance. The lock head 13 maintains the interlock with the pressing self-locking mechanism. At this time, the movable support plate 11 has been separated from the bottom wall of the foam box 2. The intelligent transport vehicle 10 is controlled by the power of the wheels of the intelligent transport vehicle 10 to leave the base 1, thereby automatically transporting the sponge.

[0040] The beneficial effects of this invention are: the intelligent transport vehicle 10 can automatically move to the bottom of the foaming box 2 under its own drive, without the need for manual handling or pushing of a trolley, which reduces the intensity of manual labor and improves the automation level of the foaming operation; By setting up a lifting support mechanism on the intelligent transport vehicle 10, and utilizing the linkage structure of the movable pallet 11, elastic element 12, lock head 13, lock device 14, and inclined transmission block 15 and inclined transmission plate 16, the movable pallet 11 can automatically move upward and abut against the bottom wall of the foaming box 2 after the intelligent transport vehicle 10 moves into place, thereby realizing automatic adjustment of the support position, avoiding leakage of foaming material, and avoiding repeated manual adjustment. By setting up a door drive mechanism consisting of an L-shaped locking rod 6, a limiting strip 5, a limiting groove 4, a transmission seat 9, a pull rope 7, and a steering wheel 8, the sliding door 3 can automatically complete the downward closing or upward opening when the movable tray 11 moves upward or the transmission seat 9 moves, thereby realizing automatic control of the opening and closing of the foaming box 2, facilitating the removal of the sponge and reducing manual intervention. Driven by cylinder 17, the piston rod of cylinder 17 abuts against the transmission seat 9 and pushes the transmission seat 9 to move. This not only enables the intelligent transport vehicle 10 to move even when there is a large friction between the movable pallet 11 and the foaming box 2, but also drives the sliding door 3 to move upward and open through the pull rope 7. Furthermore, the meshing of the transmission gear 20 and the gear 19 drives the separation tooth plate 18 to extend into the foaming cavity 21 and push the sponge. Thus, multiple linkage functions of automatic transportation, door opening and demolding are realized under the action of a single power source.

[0041] This application achieves continuous automatic execution of the foaming, opening and closing, demolding and transportation processes through the coordinated operation of the intelligent transport vehicle 10, the door drive mechanism and the sponge release mechanism. This improves production efficiency and saves labor, while reducing the time personnel spend near the foaming box 2, thereby reducing the adverse effects of gas and heat on personnel during the foaming process and improving production safety.

[0042] The components, modules, mechanisms, and devices in this invention that are not described in detail are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
