Abstract
Description
Technical Field
[0001] This utility model relates to the field of glove manufacturing technology, and in particular to a latex dipping device for latex glove production. Background Technology
[0002] The dipping process in latex glove production refers to the key step of repeatedly immersing a hand mold in a prepared latex slurry, allowing the latex to adhere evenly to the surface of the mold and naturally form a glove blank of a certain thickness.
[0003] This process typically includes multiple steps such as preheating of the hand mold, first dipping, drying, second dipping, and second drying. By controlling parameters such as latex formulation, soaking time, temperature, and hand mold rotation speed, the thickness, uniformity, and physical properties of the gloves can be effectively affected.
[0004] The latex impregnation process must ensure that the latex is stable, has few impurities, and has appropriate viscosity in order to achieve comprehensive optimization of the strength, elasticity, and wearing comfort of the finished gloves. This is one of the core links in the quality control and efficiency improvement of latex gloves.
[0005] In the latex glove production process, if a linkage mechanism is used to control the lifting and lowering of the hand mold, the viscosity of the glue and the disturbance generated during the lifting and lowering process can easily cause the glue to splash and adhere to the surface of the linkage. As the linkage moves up and down with the hand mold, it will drip, resulting in glue droplets irregularly adhering to the surface of the hand mold, forming defects such as uneven thickness, air bubbles, or edge burrs. This directly affects the uniformity and appearance quality of the gloves, and may even form solidified protrusions after drying and vulcanization, reducing comfort and yield. Utility Model Content
[0006] The purpose of this invention is to solve the problem in the existing technology where the connecting rod drips liquid onto the hand mold, which easily leads to defects in the glove forming process.
[0007] To achieve the above objectives, this utility model adopts the following technical solution: a latex dipping device for latex glove production, comprising a support plate, and further comprising: an electric push rod fixed to the upper part of the support plate; a connecting rod fixed to the lower part of the electric push rod; a hand mold fixedly installed on the lower part of the connecting rod; and an air curtain assembly, comprising a linkage plate fixed to the upper part of the connecting rod, the linkage plate being used to connect an air source, a rotating tube rotatably installed on the lower part of the linkage plate communicating with the inner cavity of the linkage plate, the lower part of the rotating tube having an air jet slit, in use, the air source is connected to the linkage plate to supply air to the rotating tube, the rotating tube receiving the air source forms a downward blowing tubular air curtain outside the connecting rod through the air jet slit, isolating splashed latex; and the air curtain gradually dissipates when it approaches the forming position of the hand mold.
[0008] In at least some embodiments, the linkage plate is fixed to the lower part of the connecting rod, the rotating tube is rotatably mounted on the upper part of the linkage plate, and the rotating tube blows upward to form the tubular air curtain.
[0009] In at least some embodiments, a blade is fixedly connected inside the rotating pipe, and multiple blades are provided.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0023] Example, according to Figures 1-4 As shown in the figure, the present invention provides a dipping device for latex glove production, including a support plate, and effectively solves the problem of hand mold forming defects caused by connecting rod contamination by setting an air curtain assembly;
[0024] Specifically, it also includes: an electric actuator, fixed to the upper part of the support plate; a connecting rod, fixed to the lower part of the electric actuator; a hand mold, fixedly installed on the lower part of the connecting rod; and an air curtain assembly, which includes a linkage plate fixed to the upper part of the connecting rod, the linkage plate being used to connect to an air source, and a rotating pipe installed at the lower part of the linkage plate communicating with the inner cavity of the linkage plate. An air jet slit is provided at the lower part of the rotating pipe. In use, an air source is connected to the linkage plate to supply air to the rotating pipe. The rotating pipe receives the air source and forms a downward-blowing tubular air curtain outside the connecting rod through the air jet slit, isolating splashed latex; and the air curtain gradually dissipates as it approaches the hand mold forming position.
[0025] During the operation of the device, the hand mold is raised and lowered by the cooperation of the electric push rod and the connecting rod to complete the glue impregnation step. In order to prevent the latex slurry from splashing and adhering to the connecting rod during the rise of the hand mold, and then dripping onto the surface of the hand mold due to gravity in subsequent movements, causing uneven molding, the device is specially equipped with an air curtain component.
[0026] The air curtain assembly includes a linkage plate fixed to the upper part of the connecting rod and a rotating tube rotatably installed at the lower part of the linkage plate. The inner cavity of the linkage plate is connected to an air source channel. When in use, the air source is delivered to the rotating tube through the linkage plate. The airflow is evenly sprayed outward through the jet gap at the lower part of the rotating tube to form a tubular air curtain extending downward along the outer wall of the connecting rod.
[0027] The air curtain surrounds the connecting rod as the hand mold approaches the latex surface and rises after being immersed in the latex, providing physical isolation and airflow scouring. It can effectively block or blow away the splashed latex, preventing it from adhering to the connecting rod and further avoiding the latex dripping and contaminating the surface of the hand mold as the connecting rod moves.
[0028] As the hand mold approaches the end point of the adhesive impregnation, the air curtain gradually diffuses outwards to prevent local airflow from affecting the hand mold, thereby maintaining the uniformity and integrity of the latex film on the surface of the hand mold and improving the quality and yield of the glove products.
[0029] In another embodiment, the linkage plate is fixed to the lower part of the connecting rod, and the rotating tube is rotatably mounted on the upper part of the linkage plate, blowing upwards to form a tubular air curtain.
[0030] To further prevent the air curtain from directly blowing onto the latex surface of the hand mold, causing uneven latex layer formation or surface disturbance, and to improve the isolation effect on splashed latex, this device features an optimized design of the air curtain component structure. The linkage plate is located at the lower part of the connecting rod, and the rotating pipe is mounted on the upper part of the linkage plate. The rotating pipe sprays air upwards, forming a bottom-up, tubular air curtain around the connecting rod, preventing the airflow from directly acting on the latex surface of the hand mold.
[0031] In this embodiment, a blade is fixedly connected inside the rotating pipe. Multiple blades are provided and are inclinedly arranged in the inner cavity of the rotating pipe. When air is injected into the rotating pipe, the blades work together to perform a spiral jet action.
[0032] Meanwhile, to enhance the turbulence diffusion capability of the air curtain, the inner cavity of the rotary tube is equipped with multiple blades arranged axially. When the air source is injected into the rotary tube, the airflow is guided by the blades to achieve a spiral rotation and spray, forming a rotating air curtain that spirals upward along the connecting rod. While covering the connecting rod, this spiral air curtain forms a turbulence layer on its outside, effectively disrupting the latex splash path and rotating it away from the connecting rod area, thereby further preventing latex from adhering to the surface of the connecting rod or dripping onto the hand mold with the movement of the connecting rod, effectively improving the latex isolation efficiency and molding stability.
[0033] In this embodiment, an automatic air supply control for the rotating spiral air curtain is achieved by setting up a linkage pneumatic system. Pneumatic components are fixedly installed on the upper part of the support plate and form a driving linkage with the linkage plate to ensure that a stable and effective air curtain isolation structure is formed during the lifting and lowering of the hand mold.
[0034] Specifically, a pneumatic component is fixedly installed on the upper part of the support plate. The drive end of the pneumatic component is fixedly connected to the linkage plate. When the linkage plate moves, the pneumatic component performs a jetting action to supply air to the rotating pipe. The pneumatic component includes a first air pipe and a second air pipe. The output end of the first air pipe is located at the upper part, and the output end of the second air pipe is located at the lower part. An inlet check valve and an outlet check valve are fixedly installed at the input and output ends of the first and second air pipes, respectively. A first piston rod and a second piston rod are slidably installed inside the first and second air pipes, respectively. The first piston rod and the second piston rod are fixed to the upper part of the linkage plate. The output ends of the first and second air pipes are connected and communicate with two air seats fixed to the upper part of the linkage plate through the first transmission pipe and the second transmission pipe, respectively. When the electric actuator drives the connecting rod to move down, the output end of the second air pipe releases air, and the first air pipe is in the intake state. When the electric actuator drives the connecting rod to move up, the output end of the first air pipe releases air, and the second air pipe is in the intake state.
[0035] The pneumatic component consists of a first air pipe and a second air pipe. The first piston rod and the second piston rod are slidably installed inside the two air pipes respectively, and both piston rods are fixedly connected to the upper part of the linkage plate. When the electric push rod drives the connecting rod to move the hand mold up and down, the linkage plate moves accordingly and drives the piston rod to slide in the air pipe, thereby generating a reciprocating airflow control action in the air pipe.
[0036] The first and second air pipes of the pneumatic component are respectively equipped with an inlet one-way valve and an outlet one-way valve to realize unidirectional airflow; the output end of the air pipe is connected to two air seats installed on the upper part of the linkage plate through the first transmission pipe and the second transmission pipe, and then communicates with the airflow cavity inside the rotating pipe.
[0037] During operation, when the electric actuator drives the connecting rod to move downward, the linkage plate descends with the connecting rod, causing the second piston rod to slide downward in the second air pipe, compressing the lower air and outputting it to the lower air seat through the second transmission pipe to supply air to the rotating tube, thus realizing the downward blowing of the rotating tube; at the same time, the first air pipe enters the suction state due to the upward movement of the piston, avoiding the formation of air resistance.
[0038] When the electric actuator drives the connecting rod to move upward, the first piston rod pushes the compressed gas upward and outputs it to the first transmission pipe and the upper air seat, realizing the upward movement of the rotating pipe to blow air, while the second air pipe is in the air intake state at this time.
[0039] This structure enables the piston to reciprocate through the displacement of the linkage plate, thereby forming an automatic, synchronous, and energy-saving airflow supply system. It provides driving force for bidirectional airflow within the rotating tube and completes continuous air supply control of the spiral air curtain without the need for a complex external control system. This ensures stable molding of the air curtain as it rises and falls with the hand mold, further improving the isolation effect of latex splatter and the consistency of molding. The air curtain intensity can also be controlled by the speed of the electric push rod.
[0040] In this embodiment, filter cartridges are fixedly installed at the inlet ends of the first and second air pipes, and filter screens for filtering impurities in the air are fixedly installed on the outside of the filter cartridges.
[0041] During operation, before the air source enters the air pipe, it first passes through a filter screen to intercept suspended dust, particles and other impurities in the air, and then passes through a filter cartridge to further purify the gas, ensuring that the airflow entering the air pipe and the rotating pipe is clean and stable. This avoids impurities entering the air curtain system and causing problems such as nozzle blockage, air curtain disorder or connecting rod contamination, thereby ensuring the normal formation and long-term reliable operation of the spiral air curtain.
[0042] The working principle of this utility model is as follows: By setting up an air curtain assembly and a linkage pneumatic system, airflow isolation is achieved for the connecting rod, preventing latex splatter from contaminating the hand mold. The electric push rod drives the connecting rod to move up and down to complete the glue impregnation process. To solve the problem of uneven molding caused by latex dripping onto the hand mold after the connecting rod is contaminated, an air curtain assembly is set on the outside of the connecting rod. This assembly consists of a linkage plate and a rotating tube. The linkage plate is connected to an air source, and the lower part of the rotating tube has an air jet gap. The gas blown out from the rotating tube forms a tubular air curtain that wraps downward or upward along the connecting rod, achieving physical isolation of the splashed latex. The rotating tube is equipped with multiple inclined... The blades create a spiral airflow when the air source is injected, constructing a spiral turbulence barrier to enhance the enveloping and repulsive force of the air curtain. Simultaneously, the air curtain assembly is automatically supplied with air through a linkage pneumatic system. The pneumatic components include two air pipes equipped with piston rods. When the hand mold moves up and down, the linkage plate drives the pistons to reciprocate, generating bidirectional air supply to the rotating pipes. This, combined with the one-way valve and transmission pipe, achieves synchronous air supply control. In addition, to ensure the cleanliness of the air source, the air pipe inlet is equipped with a filter cartridge and filter screen to prevent impurities from entering and causing nozzle blockage. The overall structure realizes an integrated, linkage, and clean air curtain isolation function.
[0043] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
