Abstract
Description
Technical Field
[0001] This utility model relates to the field of nitrile latex recycling technology, and in particular to a device for improving nitrile latex recycling. Background Technology
[0002] Nitrile rubber is a copolymer formed by the polymerization of acrylonitrile and butadiene monomers. It is mainly produced by low-temperature emulsion polymerization. It has excellent oil resistance, high wear resistance, heat resistance and strong adhesion, but its insulation performance is not ideal and its elasticity is slightly low. Nitrile rubber is mainly used to manufacture oil-resistant rubber products, and the acrylonitrile content has five different ranges.
[0003] With increasing market competition, companies are facing growing cost pressures. In the production of nitrile gloves, latex is one of the main raw materials, and its cost accounts for a considerable portion of the total cost. Therefore, the recycling of nitrile latex plays an important role.
[0004] Adding gaskets to current nitrile butadiene production equipment causes impacts when the mold base passes over it, which can damage the mold base components after prolonged wear and tear, increasing production costs.
[0005] Therefore, it is necessary to provide an improved nitrile latex recycling device to solve the above-mentioned technical problems. Utility Model Content
[0006] This invention provides an improved nitrile latex recycling device, which solves the problem that the gaskets added to the nitrile production device are prone to damage to the mold base components after long-term wear, increasing production costs.
[0007] To solve the above-mentioned technical problems, the device for improving the recycling of nitrile latex provided by this utility model includes: a mounting bracket;
[0008] The main rail is mounted on the top of the mounting bracket. A movable component is mounted on the top of the main rail. Multiple movable structures are mounted on the top of the movable component near the front and back. A mold base is mounted on the bottom of each movable structure.
[0009] The mounting components are respectively installed on the front and back of the main rail. Each mounting component has an arc-shaped pad installed on one side. Each arc-shaped pad has a dust collection groove at its bottom. Each arc-shaped pad and dust collection groove has an impact point on one side of the connection and a drop point on the other side of the connection.
[0010] The movable structure is used to install the mold base and allows the mold base to rotate. It falls within the scope of rubber product processing technology and is closely related to mold optimization, material saving, and cost control. During the production process, through the improvement of the production line structure, namely the innovative measure of adding a gasket, the excess latex is concentrated and recycled by using gravity. This achieves the goal of increasing the utilization rate of latex and increasing glove production without changing the quality of the gloves, ultimately reducing the unit product cost. By adding a gasket, the amount of latex that is thrown off can be effectively increased. The function of the gasket is that during the glove molding process, excess latex dripping from the mold will slowly drip off under the action of gravity.
[0011] Preferably, the movable component includes a mounting structure and a movable structure, the movable structure being used to mount the mounting structure onto the main rail;
[0012] The mounting structure has an internal drive mechanism, which, together with the moving structure, allows it to move along the main rail.
[0013] Preferably, the mounting bracket includes a base frame and a column, the column being used to mount the main rail on top of the base frame;
[0014] The base frame is connected to the corresponding base by bolts.
[0015] Preferably, the mounting assembly includes a mounting frame, a limiting structure, a docking structure, and a mounting plate. The limiting structure and the docking structure are threaded together to fix the docking structure inside the mounting frame, and the mounting plate is used to mount the arc-shaped gasket.
[0016] The mounting frame has openings at the top and front, and the mating structure is T-shaped to increase connection stability.
[0017] Preferably, the mounting bracket is equipped with snap-fit components on both the front and back sides, and each snap-fit component is equipped with a guide plate on one side.
[0018] The guide plate is located below the main rail, and if necessary, the top of the guide plate can be L-shaped.
[0019] Preferably, the snap-fit assembly includes a mounting component, a support structure, and a snap-fit structure. The mounting component is used to mount the support structure on the front and back of the mounting bracket, and the top opening of the support structure is used for the snap-fit structure to snap into place.
[0020] Compared with related technologies, the device for improving the recovery of nitrile latex provided by this utility model has the following beneficial effects:
[0021] This invention provides a device for improving nitrile latex recycling. To enhance recycling efficiency and reduce gasket wear, a cleverly designed arc-shaped gasket is introduced. When the mold base passes quickly, the arc-shaped gasket causes vibration, effectively throwing the latex off. This allows for concentrated recycling of the latex, significantly reducing production costs. However, due to the high speed and significant kinetic energy of the mold base, collisions and friction occur upon contact with the main rail. This intense interaction can easily damage the mold base. To mitigate this damage, the impact point and the throwing point are carefully designed. These two special design points effectively reduce the kinetic energy generated during collisions, thus significantly reducing damage to the mold base. In addition to extending its service life and reducing equipment maintenance costs, we have also specially designed a dust collection trough. This area can effectively prevent dust and residue generated by the mold from entering the final product. In this way, we can effectively guarantee the quality of the nitrile gloves produced, ensure that the products meet high standards, and enhance the competitiveness of the products in the market. By adding an arc-shaped pad, the mold will vibrate and drop when it passes quickly, and the latex can be collected and recycled, saving production costs. Through this innovative measure of adding a pad, we use gravity to promote the concentrated dropping and recycling of excess latex, thereby improving the utilization rate of latex and increasing glove production without changing the quality of the gloves, ultimately achieving the goal of reducing the unit product cost.

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0030] First Embodiment
[0031] Please refer to the following: Figure 1 , Figure 2 , Figure 3 ,in, Figure 1 A schematic diagram of the first embodiment of the device for improving the recycling of nitrile latex provided by this utility model; Figure 2 A structural schematic diagram of the movable structure is provided for this utility model; Figure 3 Provided for this utility model Figure 2 The enlarged view at point A is shown. The improved nitrile latex recovery device includes: mounting bracket 1;
[0032] Main rail 2, the main rail 2 is installed on the top of the mounting bracket 1, the top of the main rail 2 is equipped with a movable component 3, and multiple movable structures 4 are installed on the top of the movable component 3 near the front and back, and a mold base 5 is installed at the bottom of each movable structure 4.
[0033] Mounting assembly 8 is installed on the front and back of the main rail 2 respectively. One side of each mounting assembly 8 is equipped with an arc-shaped pad 6. Each arc-shaped pad 6 has a dust collection groove 10 at its bottom. One side of the connection between each arc-shaped pad 6 and the dust collection groove 10 is equipped with an impact point 9. The other side of the connection between each arc-shaped pad 6 and the dust collection groove 10 is equipped with a drop point 11.
[0034] The movable structure 4 is used to install the mold base 5 and allows the mold base 5 to rotate. This falls under the scope of rubber product processing technology and is closely related to mold optimization, material saving, and cost control. During production, through improvements to the production line structure, specifically the innovative measure of adding gaskets, excess latex is concentrated and collected using gravity. This achieves increased latex utilization and glove production without altering glove quality, ultimately reducing unit product cost. Adding gaskets effectively increases the amount of latex dropped. The gaskets act so that excess latex dripping from the mold during glove molding will slowly fall under gravity. By adding gaskets, the mold passes through specific locations where the latex is more easily dropped and collected. This allows for the saving of more latex and the production of more gloves without affecting glove weight, thereby reducing unit product cost.
[0035] The movable component 3 includes a mounting structure 301 and a movable structure 302, wherein the movable structure 302 is used to mount the mounting structure 301 on the main rail 2.
[0036] The mounting structure 301 has an internal drive structure, which, together with the moving structure 302, can move on the main rail 2.
[0037] The mounting bracket 1 includes a base frame 101 and a column 102, the column 102 being used to mount the main rail 2 on the top of the base frame 101;
[0038] The base frame 101 is connected to the corresponding base by bolts, and the column 102 adopts a high-strength hollow structure.
[0039] The mounting assembly 8 includes a mounting frame 801, a limiting structure 802, a docking structure 803, and a mounting plate 804. The limiting structure 802 and the docking structure 803 are threaded together to fix the docking structure 803 inside the mounting frame 801. The mounting plate 804 is used to mount the arc-shaped gasket 6.
[0040] The mounting frame 801 has openings at the top and front. The mating structure 803 is T-shaped to increase connection stability. The limiting structure 802 is located on both sides of the mounting frame 801.
[0041] The working principle of the improved nitrile latex recovery device provided by this utility model is as follows:
[0042] First, we cleverly introduced the arc-shaped gasket 6. When the mold base 5 passes by quickly, the arc-shaped gasket 6 causes vibration, which effectively throws the latex off. This allows the latex to be collected and recycled, greatly saving production costs. However, because the mold base 5 moves at a high speed and has considerable kinetic energy, it will collide and rub against the main rail 2. This strong interaction can easily damage the mold base 5. To mitigate this damage, we carefully designed the impact point 9 and the drop point 11. Through these two special design points, the latex can be effectively... The design significantly reduces the kinetic energy generated during collisions, thereby reducing damage to the mold base 5, extending its service life, and lowering equipment maintenance costs. In addition, we have specially designed a dust collection trough 10, which effectively prevents dust and residue generated by the mold base from entering the final product. In this way, we can effectively guarantee the quality of the nitrile gloves produced, ensure that the products meet high standards, and enhance the competitiveness of the products in the market. By adding an arc-shaped pad 6, the mold base 5 will vibrate and fall off when it passes quickly, and the latex can be collected and recycled, saving production costs.

[0047] Figure 6 Provided for this utility model Figure 5 The enlarged view at point B shows an improved nitrile latex recovery device based on the first embodiment of this application. The second embodiment of this application proposes another improved nitrile latex recovery device. The second embodiment is merely a preferred embodiment of the first embodiment, and its implementation will not affect the independent implementation of the first embodiment.
[0048] Specifically, the difference in the device for improving the recycling of nitrile latex provided in the second embodiment of this application is that the mounting bracket 1 is equipped with a snap-fit assembly 12 on both the front and back sides, and a guide plate 7 is installed on one side of the snap-fit assembly 12.
[0049] The guide plate 7 is located below the main rail 2. If necessary, the top of the guide plate 7 can be L-shaped, and the bottom ends of the two guide plates 7 have an arc facing each other to facilitate the dripping of liquid latex.
[0050] The snap-fit assembly 12 includes a mounting component 121, a support structure 122, and a snap-fit structure 123. The mounting component 121 is used to mount the support structure 122 on the front and back of the mounting bracket 1, and the top opening of the support structure 122 is used for the snap-fit structure 123 to snap into.
[0051] The front of the snap-fit structure 123 is connected to one side of the guide plate 7.
[0052] Compared with related technologies, the device for improving the recovery of nitrile latex provided by this utility model has the following beneficial effects:
[0053] To prevent latex from adhering to the mounting bracket 1 and main rail 2 during vibration, a guide plate 7 is installed on both the front and back of the mounting bracket 1 via a snap-fit assembly 12. The snap-fit structure 123 in the snap-fit assembly 12 snaps into the top of the support structure 122 to fix the guide plate 7. During actual use, the latex that drips during vibration will drip down and be collected. If there is any splashing on the guide plate 7 during this process, it will slide down along the smooth and curved guide plate 7, preventing the latex from splashing onto the mounting bracket 1 and main rail 2. This design can improve the latex recovery rate.
