Description

Technical Field

[0001] The present invention relates to the technical field of foam pouring, and particularly relates to a foam pouring system and a box body foam production line. Background Art

[0002] Foam pouring is a process of injecting foam materials (usually polyurethane, polystyrene, etc.) into a relatively enclosed space and allowing them to expand and solidify. This process can be used to manufacture lightweight materials with certain strength, heat insulation, and sound insulation properties. In foam pouring, how to completely fill the liquid into the mold box is the key in this field.

[0003] In the prior art, in order to make the bubbles of the foaming liquid in the mold box fill more evenly, the sizes tend to be consistent, and the liquid filling is more compact. Usually, a vibrator is set outside the mold box during the pouring process. However, the vibrator will gradually weaken as the vibration wave propagates. For a larger mold box, the effective range of the vibrator vibration is limited; and usually, the top surface of the liquid is the area where the vibration wave is difficult to effectively reach; if a vibrator is directly set at the top surface, it will increase unnecessary energy consumption due to the distance between the vibrator and the liquid surface at the beginning. Summary of the Invention

[0004] The purpose of the present invention is to provide a foam pouring system to solve the above deficiencies in the prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A foam pouring system includes a mold box and a pouring pipeline. The mold box includes an upper mold and a lower mold. A pressing component is arranged at the top of the upper mold. The pressing component includes a pressing plate and a pressing rod connected thereto. Liquid inlet holes and air outlet holes are formed in the pressing plate. The pouring pipeline is connected to the pressing plate through the liquid inlet holes. A step-by-step limiting component and an unlocking component are arranged on the pressing rod. The step-by-step limiting component includes a driving part connected to the top of the pressing rod; a vibration and defoaming component is arranged on the pressing component. The vibration and defoaming component includes a vibrator and a telescopic part that abuts against the pressing plate. The telescopic part gradually contracts under the movement of the pressing plate; after the vibrator strikes the foaming liquid at the set time, the liquid volume decreases and sinks, forcing the pressing plate to move down a set distance, thereby helping to unlock the pressing rod, so that the pressing rod moves up a set distance under the action of the driving part, achieving the purpose of step-by-step upward movement.

[0007] Further, the step-by-step limiting component further includes a hollow rod. A plurality of limiting plates are arranged on the inner wall of the hollow rod. A plurality of elastic parts are fixedly connected to the outer end of the pressing rod. The end of the elastic part is fixedly connected with an arc-shaped block. The top surface of the arc-shaped block is a flat structure and abuts against the corresponding limiting plate.

[0008] Further, the unlocking component includes a traction member. A sliding ring is arranged between the pressure rod and the pressing plate. An activity groove is formed at the bottom of the pressure rod. A reset member is arranged between the inner wall of the activity groove and the sliding ring. The pressing plate and the arc-shaped block are connected through the traction member. When the liquid level of the foaming liquid drops by a set distance under continuous vibration, the pressing plate also drops to the set distance under the action of the vibrator, pulling the arc-shaped block to move and unlocking it.

[0009] Further, a first magnetic ring is fixedly connected to the top surface of the sliding ring, and a second magnetic ring is fixedly connected to the inner top surface of the activity groove. The first magnetic ring and the second magnetic ring initially attract each other. When the volume of the foaming liquid decreases, the pressing plate is subjected to the vibration force of the vibrator, driving the separation of the first magnetic ring and the second magnetic ring to help unlock the arc-shaped block.

[0010] Further, the telescopic member includes a contact rod and a fixed rod. The contact rod slides inside the fixed rod. A plurality of card slots are arranged inside the fixed rod. A clamping ring is fixedly connected to the outer end of the contact rod, and the clamping ring is clamped inside the corresponding card slot.

[0011] Further, the vibration and defoaming component further includes a linkage plate. A fixed block is fixedly connected to the end of the linkage plate. The vibrator is detachably connected to the fixed block. The vibrator is electrically connected to a controller. The bottom of the contact rod is fixedly connected to the linkage plate.

[0012] Further, it further includes a workbench. A support frame is fixedly connected to the top of the workbench. The tops of the hollow rod and the fixed rod are both fixedly connected to the outer end of the support frame.

[0013] Further, the distance between multiple limiting plates is the same as the distance between multiple card slots. The outer side of the clamping ring is made of arc-shaped elastic material.

[0014] A box body foaming line applies the above foaming perfusion system, including a pouring device. The pouring device includes an infusion pump. One end of the infusion pump is connected to a pouring pipeline, and the other end is fixedly connected to a mixing tank. The mixing tank is filled with foaming liquid, and an air inflation mechanism and a mixing mechanism are further arranged inside the mixing tank.

[0015] In the above technical solution, the beneficial effects of the foaming perfusion system provided by the present invention are as follows:

[0016] Through long-term vibration by the vibrator, larger bubbles are broken by vibration waves, making the liquid and bubbles mix more evenly and the bubble sizes tend to be consistent. At this time, the gas inside the liquid overflows, the volume decreases, and the liquid level drops, causing the vibrator to push the pressing plate down a short distance. Then the pressing plate is unlocked and rises a set distance. At this time, the solenoid valve opens and liquid is continuously poured. This process is repeated, not only making the bubbles in the foaming liquid fill more evenly and the sizes more consistent, but also enabling the liquid filling volume to be more accurate, avoiding insufficient filling volume, uneven top surface or non-compliance of the length, width and height of the formed sample with the standard. By gradually vibrating and pouring, the effect of the vibrator can be fully exerted, so that its effective vibration area can cover the liquid in the corresponding area, not only can the missing liquid be filled appropriately, but also the mold box can be avoided from being incompletely filled.

[0017] It should be understood that the foregoing general description and the following detailed description are merely exemplary and explanatory and are not intended to limit the present disclosure.

[0032] To make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0033] Please refer to Figures 1 - 9, a foaming perfusion system, including a mold box 1 and a pouring pipeline 2. The mold box 1 includes an upper mold 11 and a lower mold 12. At the top of the upper mold 11, there is a pressing component 3. The pressing component 3 includes a pressing plate 31 and a pressing rod 32 connected thereto. The pressing plate 31 is provided with a liquid inlet hole and an air outlet hole 33. The pouring pipeline 2 is connected to the pressing plate 31 through the liquid inlet hole. On the pressing rod 32, there are a step-by-step limiting component 4 and an unlocking component 5. The step-by-step limiting component 4 includes a driving part 41 connected to the top of the pressing rod 32;

[0034] On the pressing component 3, there is a vibration defoaming component 6. The vibration defoaming component 6 includes a vibrator 61 abutted against the pressing plate 31 and a telescopic member 62. The telescopic member 62 gradually contracts under the movement of the pressing plate 31;

[0035] After the vibrator 61 strikes the foaming liquid for a set time, the volume of the liquid decreases and sinks, forcing the pressing plate 31 to move down a set distance, thereby helping to unlock the pressing rod 32, so that the pressing rod 32 moves up a set distance under the action of the driving part 41, achieving the purpose of step-by-step upward movement.

[0036] Specifically, the pouring pipeline 2 is made of a flexible hose material, and an electromagnetic valve is provided near the end. The amount of liquid poured each time is according to a set amount and increases gradually. A flow meter is provided in the pouring pipeline 2 as needed.

[0037] At the bottom of the upper mold 11, there is a sealing strip 13. On the top surface of the lower mold 12, there is a sealing groove 14. The sealing strip 13 and the sealing groove 14 are mutually adapted. After they fit, a good sealing relationship can be maintained. On the inner wall of the upper mold 11 near the top, there is a limiting strip 15. The pressing plate 31 finally stops below the limiting strip 15. At this time, the bottom surface of the pressing plate 31 is also the top surface of the mold.

[0038] Optionally, the pressing plate 31 is provided with a plurality of air outlet holes 33 (with a liquid-proof breathable film inside), which can make the excess gas go out from the air outlet holes 33 after the bubbles burst, and can also provide a buffering force to help the pressing plate 31 rise stably each time.

[0039] The driving part 41 is an elastic structure. In this case, an elastic rope or a strong spring can be selected. Initially, there is a set distance between the pressing plate 31 and the inner bottom surface of the lower mold 12, and the distance range is 5 - 15 cm, preferably 10 cm.

[0040] When the vibrator 61 vibrates for a long time, larger bubbles are broken by the vibration waves, making the liquid and bubbles mix more evenly and the bubble sizes tend to be consistent. At this time, the gas inside the liquid overflows, the volume decreases, and the liquid level drops, causing the vibrator 61 to push the pressing plate 31 down a small distance, with the distance range being 1 - 3 cm. Then the pressing plate 31 is unlocked and rises a set distance (also preferably 10 cm). At this time, the solenoid valve opens and liquid is continuously poured. This process is repeated, so that not only the bubbles in the foaming liquid are filled more evenly and the sizes are more consistent, but also the liquid filling amount can be more accurate, avoiding insufficient filling amount, making the top surface not flat enough or the length, width, and height of the formed sample not meeting the standards.

[0041] In the embodiment further provided by the present invention, the step-by-step limiting member 4 further includes a hollow rod 42. A plurality of limiting plates 43 are arranged on the inner wall of the hollow rod 42. A plurality of elastic members 44 are fixedly connected to the outer end of the pressure rod 32. The end of the elastic member 44 is fixedly connected with an arc-shaped block 45. The top surface of the arc-shaped block 45 is a flat structure and abuts against the corresponding limiting plate 43.

[0042] The elastic member 44 is specifically a telescopic block 441. The telescopic block 441 includes a hollow block 442 fixedly connected to the outer end of the pressure rod 32. A moving block is slidably connected inside the hollow block 442. A telescopic spring 443 is sleeved outside the moving block. The spring force is small. One end of the telescopic spring 443 is fixedly connected with the arc-shaped block 45, and the other end is fixedly connected with the outer wall of the hollow block 442. Initially, the flat surface on the top of the arc-shaped block 45 abuts against the limiting plate 43, and the limiting plate 43 is of an annular structure.

[0043] Furthermore, a guide sleeve is also provided. A guide sleeve is fixedly sleeved on the inner wall of the hollow rod 42 near the bottom. The pressure rod 32 slides inside the guide sleeve, which can limit the pressure rod 32 to move only in the vertical direction.

[0044] In the embodiment further provided by the present invention, the unlocking member 5 includes a traction member 51. A sliding ring 52 is arranged between the pressure rod 32 and the pressing plate 31. An activity groove 53 is opened at the bottom of the pressure rod 32. A reset member is arranged between the inner wall of the activity groove 53 and the sliding ring 52. The pressing plate 31 and the arc-shaped block 45 are connected through the traction member 51. When the liquid level of the foaming liquid drops a set distance under continuous vibration, the pressing plate 31 also drops to the set distance under the action of the vibrator 61, pulling the arc-shaped block 45 to move and unlocking it.

[0045] Specifically, one end of the traction member 51 movably penetrates through the moving block and is connected with the arc-shaped block 45. Optionally, it can also be directly connected to the moving block.

[0046] Furthermore, the top surface of the sliding ring 52 is fixedly connected to a first magnetic ring 54, and the inner top surface of the movable groove 53 is fixedly connected to a second magnetic ring 55. The first magnetic ring 54 and the second magnetic ring 55 initially attract each other. When the volume of the foaming liquid decreases, the pressure plate 31 is subjected to the vibration force of the vibrator 61, driving the first magnetic ring 54 and the second magnetic ring 55 to separate, thereby helping the arc block 45 to unlock.

[0047] When the vibrator 61 starts to work continuously, larger bubbles gradually burst, and the liquid and bubbles are mixed more evenly, and the liquid level begins to drop, so that the vibrator 61 can push the pressure plate 31 to move down a set distance and exceed the magnetic force between the first magnetic ring 54 and the second magnetic ring 55. Then the pressure plate 31 slides with the traction member 51, pulling the arc block 45 to move, so that the arc block 45 gradually breaks away from the interference of the limit plate 43 and quickly rises under the action of the driving member 41. During the rising process of the pressure rod 32, the pressure plate 31 and the arc block 45 are also pulled up. The arc block 45 returns to the initial position under the action of the telescopic spring 443 and stops in interference with the next layer of the limit plate 43.

[0048] In this case, the vibration force of the vibrator 61 is greater than the elastic force of the reset member plus the elastic force of the telescopic spring 443 plus the magnetic force of the first magnetic ring 54 and the second magnetic ring 55 .

[0049] In the solution further provided by the present invention, the telescopic member 62 includes a touch rod 621 and a fixed rod 622, the touch rod 621 slides inside the fixed rod 622, a plurality of slots 623 are provided inside the fixed rod 622, the outer end of the touch rod 621 is fixedly connected with a snap ring 624, and the snap ring 624 is snapped into the corresponding slot 623.

[0050] Each time, the snap ring 624 will be stuck in the corresponding slot 623, and the rising distance of the snap ring 624 is equal to the rising distance of the arc block 45, that is, the arc block 45 stops, the snap ring 624 stops, and just stops in the slot 623. The supporting force of the slot 623 to the snap ring 624 is greater than the vibration force of the vibrator 61, so that the top surface of the vibrator 61 remains stable when working, which is convenient for the pressure plate 31 to be tightly attached and effectively vibrated.

[0051] The spacing between the plurality of limiting plates 43 is the same as the spacing between the plurality of clamping grooves 623 , and the outer side of the clamping ring 624 is made of an arc-shaped elastic material.

[0052] The driving member 41 is a strong spring, and its elastic force is greater than the air damping force on the pressure plate 31 plus the clamping force between the clamping groove 623 and the clamping ring 624 (that is, the elastic force of the clamping ring 624). When the arc block 45 slides to the bottom surface of the uppermost limit plate 43, the strong spring still has sufficient elastic force, and at this time the upper mold 11 is almost filled. During the last vibration, the pressure plate 31 has reached the top, and the liquid can be poured until it is filled.

[0053] The vibration defoaming component 6 further includes a linkage plate 63. A fixing block 64 is fixedly connected to the end of the linkage plate 63. The vibrator 61 is detachably connected to the fixing block 64. The vibrator 61 is electrically connected to a controller. The bottom of the touch rod 621 is fixedly connected to the linkage plate 63.

[0054] It further includes a workbench 7. A support frame 8 is fixedly connected to the top of the workbench 7. A fixing frame 10 is fixedly connected to the side end of the support frame. The tops of the hollow rod 42 and the fixing rod 622 are both fixedly connected to the outer end of the fixing frame 10.

[0055] Two pairs of clamping strips are further arranged on the workbench 7 to support the lower mold 12. A vibrator 61 can also be arranged on the bottom surface of the lower mold 12 to continuously vibrate the liquid near the top surface.

[0056] Please refer to Figure 10 , in the present invention, there is also involved a box body foaming line which utilizes the above-mentioned foaming pouring system and includes a pouring device 9. The pouring device 9 includes an infusion pump 93. One end of the infusion pump 93 is connected to the pouring pipeline 2, and the other end is fixedly connected to a liquid storage tank 91 through a liquid outlet pipe 94. The inside of the mixing tank is filled with foaming liquid. An air inflation mechanism and a stirring mechanism are further arranged inside the mixing tank.

[0057] The stirring mechanism includes a stirring motor 92 and stirring blades connected thereto. The air inflation mechanism includes an air inflation pump and an air inlet pipe 95 connected thereto. After the foaming liquid is made, it is transported to the mold box 1 through the infusion pump 93 and the pouring pipeline 2.

[0058] Only some exemplary embodiments of the present invention have been described by way of illustration. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above-mentioned drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
