Description

Technical Field

[0001] This utility model relates to the field of nitrile latex production, and more specifically, to a latex mixing device for optimizing the weight of nitrile gloves. Background Technology

[0002] In the production of nitrile gloves, the uniformity of latex mixing plays a decisive role in the weight accuracy, physical properties, and finished product quality of the gloves. Currently, most devices used for mixing nitrile latex on the market employ traditional stirring methods, where the stirring paddle is typically fixed at a certain height on the stirring shaft, allowing only the stirring and mixing of latex within a single plane.

[0003] Existing mixing devices of this type have significant technical defects: First, they cannot achieve stratified mixing of latex at different heights within the mixing tank. Due to the density differences among the components in the latex system (such as nitrile rubber, vulcanizing agent, accelerator, stabilizer, etc.), the lack of effective stratified mixing methods during the mixing process will cause the latex to form a density gradient along the height direction within the mixing tank, resulting in stratification. This leads to uneven distribution of the components in the latex used for subsequent impregnation molding, ultimately causing significant deviations in the basis weight of different parts of the nitrile gloves. This seriously affects the stability and pass rate of product quality, making it difficult to meet the stringent requirements for basis weight precision control in the production of high-end nitrile gloves. At the same time, traditional mixing devices have insufficient capacity to handle latex adhering to the tank walls, causing latex to easily accumulate on the tank walls. This not only wastes raw materials but also causes deterioration due to prolonged local latex retention, further reducing the quality of the mixed latex.

[0004] How to invent a device for fully mixing latex to optimize the weight of nitrile gloves and solve these problems has become an urgent issue for those skilled in the art. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a latex mixing device for optimizing the weight of nitrile gloves, aiming to solve the problems mentioned in the background.

[0006] This utility model is implemented as follows:

[0007] This invention provides a device for thoroughly mixing latex to optimize the weight of nitrile gloves. The device includes a mixing tank with several support legs mounted on its side wall. A mounting base is fixedly mounted on the top of the mixing tank, and a motor is installed inside the mounting base. The output end of the motor is connected to a drive shaft, the end of which extends into the mixing tank. A mounting cylinder is connected to the lower end of the drive shaft, and a scraper is connected to the side wall of the mounting cylinder. A layered mixing assembly is mounted on the drive shaft, comprising a sliding sleeve and an electromagnet. The sliding sleeve is slidably mounted on the drive shaft. The upper part of the sliding sleeve is connected to a stirring paddle. The sliding sleeve is provided with a limit strip inside. The side wall of the drive shaft is provided with a limit groove that is adapted to the limit strip. A connecting magnetic block is fixedly connected to the upper side wall of the sliding sleeve. The connecting magnetic block is sleeved on the drive shaft. The electromagnet is fixed to the top wall of the inner cavity of the mixing tank. The electromagnet is provided with a through hole that matches the drive shaft. The electromagnet facing the connecting magnetic block and the side wall of the mounting cylinder are both connected with springs. The springs are sleeved on the outside of the drive shaft. The end of the spring located on the lower side is fixedly connected to the bottom of the sliding sleeve.

[0008] Preferably, the limiting strip has a plurality of balls rotatably engaged inside, and the outer ends of the balls abut against the bottom wall of the limiting groove.

[0009] Preferably, when the electromagnet is energized, the magnetism of the electromagnet and the opposite side of the connecting magnetic block are opposite, and the cross-section of the connecting magnetic block is arranged in a flat hexagonal shape.

[0010] Preferably, the scrapers are equidistantly distributed in a ring around the central axis of the mixing tank, and the sidewalls of the scrapers abut against the inner wall of the mixing tank.

[0011] Preferably, the top of the mixing tank is provided with a feeding port, the bottom wall of the mixing tank is provided with a discharge port, and a ball valve is provided in the discharge port.

[0012] Preferably, the number of support legs is four, and the support legs are distributed equidistantly in a ring around the central axis of the mixing tank.

[0013] The beneficial effects of this utility model are:

[0014] The layered mixing component allows the mixing paddle to agitate the latex at different heights, breaking the limitations of traditional single-height mixing. This achieves fine mixing of different layers of latex, effectively improving the uniformity of latex mixing. Uniformly mixed latex provides a stable raw material for nitrile glove production, helps optimize the weight of nitrile gloves, and reduces weight deviations caused by uneven latex mixing. The non-circular cross-section of the flat hexagonal connecting magnetic block disrupts the axial symmetry of the fluid. When the connecting magnetic block moves up and down with the sliding sleeve, local high-pressure and low-pressure zones are formed at its corners, forcing the latex to generate a lateral flow component. This lateral flow, superimposed on the axial movement of the sliding sleeve, significantly enhances the turbulence of the latex. The auxiliary mixing paddle not only breaks up agglomerates in the latex but also forcibly mixes the upper low-density latex with the lower high-density latex, effectively eliminating stratification caused by density gradients.

[0015] The scraper can promptly remove latex adhering to the inner wall of the mixing tank, allowing the latex on the tank wall to fully participate in the overall mixing process. This avoids waste caused by latex accumulation on the tank wall, improves raw material utilization, and reduces production costs. By utilizing the magnetic interaction between the electromagnet and the connecting magnetic block, combined with the spring's reset function, the height of the stirring paddle can be flexibly adjusted by controlling the on and off of the electromagnet. This allows for rapid adjustment of the stirring level and intensity according to different latex formulations and mixing requirements, enhancing the applicability of the device.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Example, refer to Figures 1-5 A latex mixing device for optimizing the weight of nitrile gloves includes a mixing tank 1. Several support legs 13 are mounted on the side wall of the mixing tank 1. A mounting base 21 is fixedly mounted on the top of the mixing tank 1. A motor 2 is installed inside the mounting base 21. The output end of the motor 2 is connected to a drive shaft 3. The end of the drive shaft 3 extends into the interior of the mixing tank 1. A mounting cylinder is connected to the lower end of the drive shaft 3. A scraper 4 is connected to the side wall of the mounting cylinder. A layered mixing assembly is provided on the drive shaft 3. The layered mixing assembly includes a sliding sleeve 6 and an electromagnet 8. The sliding sleeve 6 is slidably mounted on the drive shaft 3. A stirring paddle 61 is connected to the outer side of the sliding sleeve 6. A limit strip 7 is provided inside the sliding sleeve 6. A limit groove 31 adapted to the limit strip 7 is opened on the side wall of the drive shaft 3. The limit strip 7 cooperates with the limit groove 31 to ensure that the sliding sleeve 6 will not rotate circumferentially during the sliding process, but can only slide axially along the drive shaft 3. A connecting magnetic block 5 is fixedly connected to the upper side wall of the sliding sleeve 6. The connecting magnetic block 5 is sleeved on the drive shaft 3. The electromagnet 8 is fixed to the top wall of the inner cavity of the mixing tank 1. The electromagnet 8 is provided with a through hole that matches the drive shaft 3. The electromagnet 8 facing the connecting magnetic block 5 and the side wall of the mounting cylinder are both connected with springs 9. The springs 9 are sleeved on the outside of the drive shaft 3. The end of the spring 9 located on the lower side is fixedly connected to the bottom of the sliding sleeve 6. The springs 9 play a role in buffering and resetting during the movement of the sliding sleeve 6, making the movement of the sliding sleeve 6 more stable. At the same time, when the electromagnet 8 is de-energized, the sliding sleeve 6 can return to the initial position.

[0025] It should be noted that when the electromagnet 8 is energized, the magnetism of the electromagnet 8 and the opposite side of the connecting magnetic block 5 are opposite, thus generating an attractive force. By controlling the on and off of the electromagnet 8, the position of the sliding sleeve 6 is adjusted, thereby changing the height of the stirring paddle 61, so as to achieve full mixing of different layers of latex. The cross-section of the connecting magnetic block 5 is set in a flat hexagonal shape. The scraper 4 is distributed equidistantly in a ring around the central axis of the mixing tank 1. The side wall of the scraper 4 abuts against the inner wall of the mixing tank 1, which can scrape off the latex adhering to the tank wall during the mixing process, avoiding the accumulation of latex on the tank wall and affecting the mixing effect. At the same time, it also helps to involve the latex near the tank wall in the overall mixing.

[0026] Reference Figures 3-5 The limiting strip 7 has several ball bearings 71 inside, which rotate and engage. The outer ends of the ball bearings 71 abut against the bottom wall of the limiting groove 31. The ball bearings 71 make the position adjustment of the stirring paddle 61 smoother. The top of the mixing tank 1 has a feeding port 11, and the bottom wall of the mixing tank 1 has a discharge port 12. The discharge port 12 is equipped with a ball valve 121. The feeding port 11 makes it easy to add latex and other additives into the mixing tank 1. The ball valve 121 can control the flow of latex, so that the latex can be discharged after mixing for subsequent production of nitrile gloves. There are four support legs 13. The support legs 13 are distributed equidistantly in a ring around the central axis of the mixing tank 1 to ensure the stability of the mixing tank 1 and prevent the device from shaking during the mixing process, thus avoiding affecting the latex mixing effect.

[0027] The working principle of this latex mixing device for optimizing the weight of nitrile gloves is as follows: First, nitrile latex and related additives are added into the mixing tank 1 in proportion through the feeding port 11 at the top of the mixing tank 1. Then, the motor 2 is started. The power of the motor 2 is transmitted to the transmission shaft 3 through the mounting base 21, which drives the transmission shaft 3 to start rotating. The rotation of the transmission shaft 3 causes the mounting cylinder connected to the lower end to rotate accordingly. The scraper 4 on the side wall of the mounting cylinder rotates in a ring around the central axis of the mixing tank 1. Because its side wall abuts against the inner wall of the mixing tank 1, it can continuously scrape off the latex adhering to the tank wall to prevent latex accumulation. At the same time, it pushes the latex near the tank wall into the mixing tank 1 to participate in the overall mixing.

[0028] Meanwhile, the layered stirring assembly on the drive shaft 3 begins to function. In the initial state, the electromagnet 8 is not energized, and the sliding sleeve 6 is in its initial position under the support of the lower spring 9. At this time, the stirring paddle 61 connected to the outside of the sliding sleeve 6 performs regular stirring of the latex. When it is necessary to adjust the stirring layers, the electromagnet 8 is energized. Since the electromagnet 8 and the connecting magnetic block 5 have opposite magnetic properties, they generate an attraction force. The electromagnet 8 pulls the connecting magnetic block 5, which in turn drives the sliding sleeve 6 to overcome the elastic force of the lower spring 9 and slide upward along the drive shaft 3. The limiting strip 7 inside the sliding sleeve 6 cooperates with the limiting groove 31 on the side wall of the drive shaft 3 to ensure that the sliding sleeve 6 can only move axially during the sliding process and will not rotate circumferentially. As the sliding sleeve 6 moves upward, the stirring paddle 61 reaches a higher position to stir the upper layer of latex. The ball 71 inside the limiting strip 7 rotates and engages with the bottom wall of the limiting groove 31, reducing the friction of the sliding sleeve 6 during sliding and making the position adjustment of the stirring paddle 61 smoother.

[0029] When the power supply to the electromagnet 8 is stopped, the attraction disappears, and under the action of the lower spring 9, the sliding sleeve 6 returns to its initial position, and the stirring paddle 61 also returns to its original height to continue regular stirring. By controlling the on and off of the electromagnet 8 multiple times, the stirring paddle 61 can stir the latex in layers at different heights, so that the latex can be fully mixed in each layer in the mixing tank 1. After the mixing is completed, the ball valve 121 in the discharge port 12 is opened, and the latex can be discharged from the discharge port 12 for the production of nitrile gloves.

[0030] The non-circular cross-section of the flat hexagon of the connecting magnetic block 5 disrupts the axial symmetry of the fluid. When the connecting magnetic block 5 moves up and down with the sliding sleeve 6, local high-pressure and low-pressure zones are formed at its corners, forcing the latex to generate a lateral flow component. This lateral flow, superimposed on the axial movement of the sliding sleeve 6, significantly enhances the turbulence of the latex. The auxiliary stirring paddle 61 can not only break up agglomerates in the latex, but also forcibly mix the upper low-density latex with the lower high-density latex, effectively eliminating the stratification phenomenon caused by the density gradient.

[0031] The layered mixing assembly allows the mixing paddle 61 to mix latex at different heights, breaking the limitations of traditional single-height mixing. This achieves fine mixing of different layers of latex, effectively improving the uniformity of latex mixing. Uniformly mixed latex provides a stable raw material for nitrile glove production, helps optimize the weight of nitrile gloves, and reduces weight deviation caused by uneven latex mixing. The scraper 4 can promptly scrape off the latex adhering to the inner wall of the mixing tank 1, allowing the latex on the tank wall to fully participate in the overall mixing process, avoiding waste caused by latex accumulation on the tank wall, improving raw material utilization, and reducing production costs. Utilizing the magnetic interaction between the electromagnet 8 and the connecting magnetic block 5, combined with the reset function of the spring 9, the height of the mixing paddle 61 can be flexibly adjusted by controlling the on and off of the electromagnet 8. This allows for rapid adjustment of the mixing layer and intensity according to different latex formulations and mixing requirements, enhancing the applicability of the device.
