Description

Technical Field

[0001] The utility model relates to the technical field related to foaming sponges, in particular to a shaping device for anti-allergic foaming sponges. Background Art

[0002] Due to its excellent comfort performance, polyurethane slow-rebound foam has been widely used in household goods, automobiles, shoes, medical equipment and other fields. Due to its unique molecular structure, polyurethane slow-rebound foam has high comfort performance. When subjected to a certain pressure, the polyurethane slow-rebound foam will change its shape with the pressure, so that the pressure is evenly distributed and the local stress points are reduced. After the pressure is released, its shape slowly returns to its original state. However, due to its own closed-cell structure, the air permeability and damping sound absorption performance of polyurethane slow-rebound foam are poor.

[0003] Sponge is a kind of polyurethane foam plastic, belonging to soft polyurethane foam plastic. Due to its porous honeycomb structure, it has excellent softness, elasticity, water absorption and water resistance, and is widely used in sofas, mattresses, clothing, soft packaging and other industries.

[0004] The main pollution-producing links of the production line based on the foaming sponge process include batching, weighing, mixing, foaming, shaping, vulcanization and drying. The weighing, mixing and foaming processes will produce air pollutants such as dust and NH3, and the shaping, vulcanization and drying processes will produce air pollutants such as volatile organic compounds (VOCs) and H2S. The air pollutants generated by the entire foaming sponge production line will be aggregated to form a mixed exhaust gas including dust, NH3, H2S and VOCs.

[0005] During the shaping process of existing foam sponges, the volatile organic compounds emitted are not well treated and are easily left around the production line, causing certain impacts on the workers. Utility Model Content

[0008] Beneficial effects: The foaming sponge is transmitted through the inner cylinder, and then the material is transported to the shaping cover for the foaming sponge shaping device. The inner cylinder and the shaping cover are not directly connected, so as to ensure that the discharge port on the lower side of the inner cylinder can be movable, and ensure that the inside of the shaping cover is fully filled. At the same time, the gap between the main cylinder and the inner cylinder is used to collect waste gas, and the waste gas is collected by the gas storage structure, which can prevent the waste gas from leaking out at will and reduce the impact on the staff. At the same time, due to the separation of the inner cylinder and the main cylinder, the reflux of waste gas from the inner cylinder can also be reduced, thereby improving the recovery rate of waste gas and ensuring the collection effect.

[0009] Furthermore, the gas storage structure includes a sealing plate, which is fixedly connected to the outer wall of the inner tube and abuts against the inner wall of the main tube. When working, the sealing plate slides up and down following the inner tube.

[0010] Furthermore, the inner tube is fixedly connected with a second transparent plate, the second transparent plate abuts against the inner wall of the main tube, the inner wall of the main tube is fixedly mounted with a first transparent plate, the first transparent plate abuts against the outer wall of the inner tube, and the first transparent plate and the second transparent plate are both provided with a plurality of air holes penetrating upward and downward, and the upper and lower air holes are staggered.

DETAILED DESCRIPTION

[0021] See Figures 1 to 4 As shown, a shaping device for anti-allergic foam sponge includes a base 12, wherein the base 12 is a shaping platform, and the lower side of the base 12 is connected with four legs for supporting work to ensure stable shaping work, and at the same time, one side of the base 12 is connected with a bracket 11, and the bracket 11 and the base 12 are both supported by the legs, and the bracket 11 is used to place the formed foam sponge.

[0022] The upper end of the base 12 is fixedly connected with a connecting frame 13 , and four supporting legs are also arranged between the connecting frame 13 and the base 12 , which are supported and fixed by the supporting legs to ensure stability.

[0023] The connecting frame 13 is slidably connected to a main cylinder 34, which is located at the center of the connecting frame 13. The main cylinder 34 passes through the connecting frame 13, and the upper and lower ends of the main cylinder 34 extend out of the connecting frame 13. The lower end of the main cylinder 34 is connected to a shaping cover 21 below the connecting frame 13. The shaping cover 21 is used to define the shape of the foaming sponge. The shaping cover 21 has openings at the top and bottom, and the upper opening of the shaping cover 21 is connected to the main cylinder 34, thereby realizing shaping feeding and discharging after shaping.

[0024] The shaping cover 21 and the main tube 34 are fixedly connected to prevent the foaming sponge from leaking in the gap. When the shape needs to be changed, the shaping cover 21 and the main tube 34 are disassembled at the same time.

[0025] In order to ensure that the filling is more rapid, the present application provides an inner cylinder 35 inside the main cylinder 34 , and the inner cylinder 35 is not connected to the main cylinder 34 .

[0026] The outer diameter of the inner cylinder 35 is smaller than the inner diameter of the main cylinder 34. The gap between the inner cylinder 35 and the main cylinder 34 is used to collect the waste gas generated by the foaming sponge during the shaping process. Therefore, the lower end of the inner cylinder 35 extends downward into the inner side of the shaping cover 21, which can ensure that the foaming sponge is completely filled in the shaping cover 21, ensure the normal shaping work, and prevent the waste gas from flowing back through the inner cylinder 35 and being discharged from the gap between the inner cylinder 35 and the main cylinder 34.

[0027] The upper end of the inner cylinder 35 extends out of the main cylinder 34. The upper end of the inner cylinder 35 is used to connect to the injection mechanism to perform injection work from the outside. In the present application, the injection mechanism does not affect the progress of the shaping work and is not set up. The user can adjust the connection work according to the actual situation to ensure that the shaping work is carried out.

[0028] Furthermore, the gap between the inner tube 35 and the main tube 34 is used to guide and collect the exhaust gas, but the upper end of the main tube 34 is provided with an opening, and the exhaust gas is easily discharged to the outside, and the collection effect cannot be achieved.

[0029] Therefore, a sealing plate 23, a first transparent plate 24, and a second transparent plate 25 are provided at the gap between the inner tube 35 and the main tube 34 to realize corresponding sealing and collecting work.

[0030] The sealing plate 23 is located on the upper side of the inner wall of the main cylinder 34. The sealing plate 23 is fixedly connected to the outer wall of the inner cylinder 35. The outer ring of the sealing plate 23 abuts against the inner wall of the main cylinder 34. A rubber ring can be provided on the outer ring of the sealing plate 23 to ensure the sealing performance while facilitating the up and down movement of the sealing plate 23. The up and down movement of the sealing plate 23 causes the air pressure in the gap between the main cylinder 34 and the inner cylinder 35 to better guide the exhaust gas to the gap between the inner cylinder 35 and the main cylinder 34.

[0031] Furthermore, the sealing plate 23 is connected to a conduit 22, the lower end of the conduit 22 is connected to and penetrates the sealing plate 23, the upper end of the conduit 22 extends out of the main tube 34, and the upper end of the conduit 22 can be freely connected to a gas storage device or an air extraction device outside the main tube 34, so that the exhaust gas in the gap is discharged through the conduit 22. The gas storage device or the air extraction device does not affect the exhaust work of the conduit 22, and is not limited in this embodiment, and the technicians can adjust it freely.

[0032] Among them, Figure 4As shown, the inner cylinder 35 is fixedly connected with the second transparent plate 25, and the second transparent plate 25 abuts against the inner wall of the main cylinder 34. The first transparent plate 24 is fixedly installed on the inner wall of the main cylinder 34. The sealing plate 23, the first transparent plate 24, and the second transparent plate 25 are all annular plates of the same size, and the sealing plate 23, the first transparent plate 24, and the second transparent plate 25 are arranged in sequence from top to bottom. The first transparent plate 24 abuts against the outer wall of the inner cylinder 35. The first transparent plate 24 and the second transparent plate 25 are each provided with a plurality of air holes 26 that penetrate up and down. The air holes 26 are arranged in a circular array, and the upper and lower air holes 26 are staggered. When the first transparent plate 24 and the second transparent plate 25 abut, any transparent plate will block the air holes 26 on the other transparent plate. At this time, no gas exchange is performed, which can prevent the collected exhaust gas from flowing back. The second transparent plate 25 will move synchronously with the inner cylinder 35 and the sealing plate 23, and the first transparent plate 24 is in a fixed state.

[0033] In this embodiment, the first transparent plate 24 and the second transparent plate 25 will be separated only when the inner cylinder 35 moves downward. At this time, the gap and the internal space of the shaping cover 21 are in a pressurized state, which facilitates the exhaust gas to flow upward and be discharged from the duct 22. At the same time, it also facilitates the shaped sponge to fall from the shaping cover 21 for easy removal.

[0034] The lifting device includes a driving base 31, and the driving base 31 is fixedly connected to the upper end surface of the connecting frame 13. The driving base 31 is respectively connected to the first connecting frame 32 and the second connecting frame 33 through telescopic rods. The driving base 31 is used to drive the telescopic rod to move up and down, and the telescopic rod of the first connecting frame 32 and the telescopic rod of the second connecting frame 33 are not the same components, and can move independently. The driving base 31 serves as a power output end. In this embodiment, an air pump or an oil pump can be selected to facilitate the extension and contraction of the telescopic rod. The first connecting frame 32 is fixedly connected to the inner cylinder 35, and the second connecting frame 33 is fixedly connected to the main cylinder 34.

[0035] The second connecting frame 33 is located above the first connecting frame 32 to prevent the inner cylinder 35 and the main cylinder 34 from being separated.

[0036] The upper end surface of the base 12 is provided with a deformation groove 14 , in which a support plate 16 is slidably installed up and down, and a spring 15 is provided between the support plate 16 and the bottom wall of the deformation groove 14 .

[0037] Working principle:

[0038] First, check the connection of the base, connecting frame, main cylinder, shaping cover, inner cylinder and each part to ensure that there is no looseness or damage. Check the gas storage structure and sealing plate to ensure that the seal is intact and there is no air leakage. Confirm the connection between the duct and the vacuum pump to ensure that it is unobstructed. Then, prepare the foam sponge material that needs to be shaped and ensure that the material is free of impurities. Check the injection mechanism to ensure that the material can be smoothly injected into the inner cylinder.

[0039] Start the driving base, ensure the normal operation of the telescopic rod and the connecting frame, debug the lifting device of the inner tube and the main tube, and ensure that they can move up and down smoothly. Ensure that the duct and the vacuum pump are connected normally, start the vacuum pump for trial operation, and check whether the exhaust gas collection and discharge are normal.

[0040] The foam sponge material is injected into the inner cylinder through the injection mechanism to ensure that there is enough material in the inner cylinder. The inner cylinder transports the material to the shaping cover and starts the shaping operation of the foam sponge. During the shaping process, the gap between the inner cylinder and the main cylinder is monitored to ensure that the exhaust gas can be effectively collected.

[0041] The waste gas generated during the molding process is collected by the gas storage structure through the gap between the inner tube and the main tube. The sealing plate slides up and down with the inner tube to prevent the waste gas from leaking out. The waste gas is discharged into the gas storage device or the air extractor through the duct to ensure the cleanliness of the working environment.

[0042] When the shaping process is completed, stop injecting and move the inner cylinder upward to ensure that the foam sponge in the shaping cover is formed. Stop the equipment and wait for the foam sponge in the shaping cover to cool and stabilize.

[0043] Take the shaped foam sponge out of the shaping cover and place it on the bracket. Check the shaping effect of the foam sponge to ensure that the shape and quality meet the requirements.

[0044] Clean the residual materials and exhaust gas collection devices inside and outside the equipment to ensure the equipment is clean before the next use. Regularly check the wear of various parts of the equipment, perform necessary maintenance and replacement to ensure the long-term use of the equipment.

[0045] This device transfers the foaming sponge material through the inner cylinder, and transports the material to the shaping cover for shaping. The inner cylinder and the shaping cover are not directly connected, ensuring that the discharge port on the lower side of the inner cylinder can move, and ensuring that the inside of the shaping cover is fully filled. The gap between the main cylinder and the inner cylinder is used to collect the waste gas generated during the shaping process, and the waste gas is stored through the gas storage structure. The gas storage structure includes a sealing plate, a first transparent plate and a second transparent plate. The sealing plate slides up and down with the inner cylinder to ensure that the waste gas is effectively guided to the duct and discharged through the vacuum pump to prevent the waste gas from leaking. The lifting device includes a driving base, a first connecting frame and a second connecting frame. The lifting and lowering of the inner cylinder and the main cylinder are achieved through a telescopic rod to ensure the smooth progress of the shaping operation. Finally, through a series of mechanical movements and sealing structures, the shaping of the foaming sponge and the effective collection and treatment of waste gas are achieved.
