Description

Technical Field

[0001] This utility model relates to the technical field of latex glove production equipment, and in particular to an inclined dip-dipping device for producing latex gloves. Background Technology

[0002] Latex gloves are highly elastic and form-fitting protective gear made primarily from natural latex through an impregnation molding process. Due to their excellent flexibility, sealing properties, and biocompatibility, they are widely used in various fields such as medical care, food processing, electronics manufacturing, chemical operations, and daily cleaning. As a core process in latex glove production, the impregnation stage directly determines the uniformity of glove thickness, surface smoothness, and physical properties, thus placing extremely high demands on the structural design and process control of the impregnation equipment. An ideal impregnation process must ensure that the mold is uniformly and stably impregnated in the latex solution, forming a consistent thickness and defect-free film during the lifting process. This has a decisive impact on subsequent vulcanization, demolding, and the quality of the finished product.

[0003] Existing latex glove dipping equipment mostly uses a vertical dipping method, and the adhesive tank structure is fixed, lacking dynamic stirring or circulation mechanisms. In actual production, because the latex solution contains fillers, vulcanizing agents, and other additives, it is prone to sedimentation or stratification after prolonged standing, resulting in uneven adhesive concentration. When the glove mold is immersed in such a heterogeneous adhesive solution, it can cause localized areas of excessively thin or thick adhesive film, seriously affecting the consistency and mechanical properties of the product. Utility Model Content

[0004] The purpose of this invention is to provide an inclined dipping device for producing latex gloves, which solves the problems of existing latex glove dipping devices that mostly use vertical dipping methods and have fixed glue tank structures and lack dynamic stirring or circulation mechanisms.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A tilting dip-coating device for producing latex gloves includes a dip-coating tank and two slide rails symmetrically arranged on the top of the tank. The bottom of each slide rail is connected to the side wall of the dip-coating tank via a vertical lifting structure. A movable frame is slidably connected to the top of each slide rail. Two mounting rods are connected between the two movable frames. Each mounting rod has several clamps at its bottom, and the top of each clamp is connected to the bottom of the mounting rod via a connecting structure. A horizontal drive structure for cooperating with the movable frame is provided on one side of each slide rail. A stirring blade is installed at the center of the bottom of the dip-coating tank. A drive module cooperating with the stirring blade is provided at the bottom of the dip-coating tank. Baffles are provided around the inside of the dip-coating tank, and lifting modules cooperating with the baffles are provided around the outer wall of the dip-coating tank.

[0006] Preferably, support frames are fixedly connected to both sides of the bottom of the impregnation tank, and the support frames are made of metal.

[0007] Preferably, the vertical lifting structure includes a lifting cylinder connected to the side wall of the impregnation tank via a side frame and a lifting plate disposed on the top of the side frame. The output end of the lifting cylinder is connected to the bottom of the lifting plate, and the top of the lifting plate is connected to the bottom of the slide rail via a support frame.

[0008] Preferably, a U-shaped frame is connected to the top of the spoiler, and one end of the U-shaped frame is connected to the output end of the lifting module.

[0009] Preferably, the horizontal drive structure includes a drive motor connected to the slide rail sidewall via a mounting base, the output shaft of the drive motor being connected to a drive gear disk, and a toothed plate that engages with the drive gear disk via a locking tooth being connected to the inner bottom of the moving frame.

[0010] Preferably, the connecting structure includes a connecting rod and an inclined rod, one end of the connecting rod being connected to the bottom of the mounting rod and the other end being connected to the end of the inclined rod, and one end of the inclined rod being connected to a clamp.

[0011] This utility model has the following beneficial effects: This solution incorporates stirring blades driven by a drive module at the bottom of the impregnation tank, along with surrounding liftable baffles and their corresponding lifting modules, forming a composite flow field of "central stirring + edge turbulence." This significantly improves the suspension stability and concentration uniformity of the adhesive solution, ensuring consistent adhesive composition for each mold impregnation and fundamentally improving film thickness fluctuations and local defects. Addressing the issue of significant thickness differences between the upper and lower ends of gloves caused by gravity in traditional vertical impregnation, this equipment uses a combination of slide rails, a vertical lifting structure, and a moving frame to maintain a controllable tilt during impregnation and removal. This alters the flow direction and distribution pattern of the adhesive solution on the mold surface, effectively mitigating the non-uniform accumulation of adhesive solution under gravity.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] Example 1 Please see Figure 1-5 As shown, this embodiment of an inclined dipping device for producing latex gloves includes a dipping tank 1 and two slide rails 11 symmetrically arranged on the top of the dipping tank 1. The bottom of the slide rails 11 is connected to the side wall of the dipping tank 1 via a vertical lifting structure. A movable frame 4 is slidably connected to the top of the slide rails 11. Two mounting rods 3 are connected between the two movable frames 4. Several clamps 2 are provided at the bottom of each mounting rod 3. The top of each clamp 2 is connected to the bottom of the mounting rod 3 via a connecting structure. A horizontal drive structure for cooperating with the movable frame 4 is provided on one side of the slide rails 11. A stirring blade 5 is installed at the center of the bottom of the dipping tank 1. A drive module cooperating with the stirring blade 5 is provided at the bottom of the dipping tank 1. Baffles 6 are provided around the inside of the dipping tank 1. Lifting modules 7 cooperating with the baffles 6 are provided around the outer wall of the dipping tank 1.

[0017] In the actual operation of the inclined dipping device for producing latex gloves according to the present invention, several glove molds are first fixed to the bottom of the mounting rod 3 by clamps 2. The clamps 2 and the mounting rod 3 adopt a detachable connection structure for easy replacement or maintenance. Two mounting rods 3 are horizontally mounted between two moving frames 4, forming a dipping module that can support multiple rows of molds. After the equipment is started, the horizontal drive structure drives the moving frame 4 to move horizontally along the slide rail 11 to a preset position directly above the dipping tank 1. Then, the vertical lifting structure controls the slide rail 11 and the entire module on it to descend synchronously, so that the molds are slowly immersed in the latex liquid in the dipping tank 1 at a set tilt angle. During this process, the drive module at the bottom of the dipping tank 1 continuously drives the stirring blades 5 to rotate at a low speed, gently and evenly stirring the latex liquid to prevent fillers and additives from settling due to statication. At the same time, the baffles 6 set around the inner wall of the dipping tank 1 move up and down periodically under the drive of the lifting module 7, further agitating the boundary layer of the latex liquid, breaking the local concentration gradient, and enhancing the overall uniformity and fluidity of the latex liquid. After the predetermined impregnation time is completed, the vertical lifting structure drives the mold to be lifted out of the liquid surface at the same tilt angle and at a uniform speed. During this lifting phase, because the mold is not lifted vertically but maintains a certain tilt angle, the downward flow path of the adhesive under gravity is effectively extended and dispersed, avoiding the problem of the adhesive rapidly accumulating at the bottom of the glove, resulting in an excessively thin top and an excessively thick bottom, which is common with traditional vertical lifting. After the lifting is completed, the horizontal drive structure moves again, moving the moving frame 4 along with the mold out of the impregnation area and into the subsequent degreasing or pre-vulcanization stage, thus completing one complete impregnation cycle. Throughout the process, the tilt impregnation angle, lifting speed, stirring intensity, and turbulence frequency can all be parametrically adjusted according to the glove specifications and adhesive characteristics, achieving flexible process control.

[0018] Example 2 Please see Figure 1-5 As shown in this embodiment, an inclined dipping device for producing latex gloves has a dipping tank 1 with support frames fixedly connected to both sides of the bottom. The support frames are made of metal. Specifically, through the setting of the stirring blade 5 installed at the center of the bottom of the dipping tank 1 and the drive module set at the bottom of the dipping tank 1, the drive module drives the stirring blade 5 to rotate continuously at a low speed, so as to gently and evenly stir the latex liquid, prevent fillers, vulcanizing agents and other additives from settling or separating during the standing process, and achieve the effect of maintaining the overall uniformity of the glue concentration and avoiding uneven glue thickness or surface defects of the gloves due to local component differences.

[0019] The top of the spoiler 6 is connected to a U-shaped frame, one end of which is connected to the output end of the lifting module 7. Specifically, through the setting of two symmetrically arranged slide rails 11 at the top of the impregnation tank 1, a vertical lifting structure connected to the bottom of the slide rails 11, and a movable frame 4 slidably connected to the top of the slide rails 11, the vertical lifting structure controls the slide rails 11 and the movable frame 4 to rise and fall synchronously as a whole, and makes the mold installed on the movable frame 4 immerse and lift the latex at a preset tilt angle. This changes the unidirectional flow path of the latex under gravity in the traditional vertical impregnation method, and achieves the effect of alleviating the downward accumulation of latex, improving the difference in the thickness of the glue layer at the top and bottom of the glove, and improving the consistency of product thickness.

[0020] Example 3 Please see Figure 1-5 As shown in this embodiment, an inclined dipping device for producing latex gloves includes a vertical lifting structure comprising a lifting cylinder 15 connected to the side wall of the dipping tank 1 via a side frame 19 and a lifting plate 9 disposed on the top of the side frame 19. The output end of the lifting cylinder 15 is connected to the bottom of the lifting plate 9, and the top of the lifting plate 9 is connected to the bottom of the slide rail 11 via a support frame 10. Specifically, through the arrangement of a baffle 6 disposed around the inside of the dipping tank 1 and a lifting module 7 disposed around the outside of the dipping tank 1, the lifting module 7 periodically drives the baffle 6 to move up and down, disturbing the boundary layer of the latex liquid near the inner wall of the dipping tank 1, breaking the concentration gradient formed by stillness or low flow rate, enhancing the overall fluidity and mixing uniformity of the latex liquid, and achieving the effect of further improving the suspension stability of the latex liquid and assisting the stirring blades 5 to achieve more comprehensive and uniform stirring.

[0021] The horizontal drive structure includes a drive motor 13 connected to the side wall of the slide rail 11 via a mounting base 14. The output shaft of the drive motor 13 is connected to a drive gear disk 12. The inner bottom of the moving frame 4 is connected to a toothed plate 16 that engages with the drive gear disk 12 via a locking tooth. The bottom of the lifting plate 9 is fixedly connected to several guide rods 8, one end of which slides through the side frame 19. Specifically, through the setting of the horizontal drive structure on one side of the moving frame 4 and the slide rail 11, the horizontal drive structure drives the moving frame 4 to move precisely horizontally along the slide rail 11, realizing the automatic transfer of the mold module between the dipping station and the subsequent station. This avoids manual handling or positioning deviation, thereby improving the automation level of the equipment, ensuring the repeatability accuracy of the dipping position, and improving the stability of the production cycle.

[0022] The connecting structure includes a connecting rod 18 and an inclined rod 17. One end of the connecting rod 18 is connected to the bottom of the mounting rod 3, and the other end is connected to the end of the inclined rod 17. One end of the inclined rod 17 is connected to the clamp 2. Specifically, through the detachable connection structure between the clamps 2 at the bottom of the mounting rod 3 and the mounting rod 3, the operator can quickly change or adjust the position and number of clamps 2 according to different models of glove molds without disassembling the entire module. This achieves the effects of improving the equipment's adaptability to multiple product specifications, shortening changeover time, and facilitating maintenance and cleaning.

[0023] In the complete workflow of the inclined dipping device for producing latex gloves according to the present invention, multiple glove molds are first installed on the fixture 2. The fixture 2 is connected to the mounting rod 3 through a connecting structure. The connecting structure specifically includes a connecting rod 18 and an inclined rod 17. One end of the connecting rod 18 is fixed to the bottom of the mounting rod 3, and the other end is hinged to the end of the inclined rod 17. The other end of the inclined rod 17 is connected to the fixture 2. This inclined arrangement not only enhances the structural stability but also facilitates the adjustment of the mold posture. The two mounting rods 3 are horizontally fixed between two moving frames 4 to form a dipping module that can support multiple rows of molds. After the equipment is started, the horizontal drive structure composed of the drive motor 13 begins to work. The drive motor 13 is fixed to the side wall of the slide rail 11 through the mounting base 14. Its output shaft drives the drive gear disk 12 to rotate. The drive gear disk 12 meshes with the toothed plate 16 fixed to the bottom of the moving frame 4, thereby driving the moving frame 4 to move precisely horizontally along the slide rail 11 to a preset position directly above the dipping tank 1. Subsequently, the vertical lifting structure operates: This structure includes a lifting cylinder 15 fixed to the side wall of the impregnation tank 1 via a side frame 19, a lifting plate 9 installed on the top of the side frame 19, and a support frame 10 connecting the lifting plate 9 to the bottom of the slide rail 11; the lifting cylinder 15 extends and retracts, causing the lifting plate 9 to move up and down, and then the support frame 10 simultaneously drives the slide rail 11 and the entire moving frame 4 module to move vertically up and down. At the same time, due to the assembly relationship between the slide rail 11 and the moving frame 4 and the tilt angle design of the inclined rod 17 in the connecting structure, the mold naturally forms a set tilt posture during the descent and slowly immerses itself in the latex liquid in the impregnation tank 1. During this impregnation stage, the stirring blade 5 at the center of the bottom of the impregnation tank 1 rotates continuously at a low speed under the drive of the drive module, gently stirring the adhesive. Simultaneously, the baffle 6 moves periodically up and down under the drive of the lifting module 7. A U-shaped frame is connected to the top of the baffle 6, with one end connected to the output end of the lifting module 7, thereby causing the baffle 6 to disturb the adhesive boundary layer near the inner wall of the impregnation tank 1. Furthermore, metal support frames are provided on both sides of the bottom of the impregnation tank 1 to enhance the overall structural rigidity and ensure the stability of the equipment during long-term operation. After the predetermined impregnation time is completed, the lifting cylinder 15 reverses its movement, causing the lifting plate 9 to rise. The guide rod 8, as a guiding component, has one end fixed to the bottom of the lifting plate 9 and the other end sliding through the side frame 19, ensuring a smooth and unbiased lifting process. This allows the mold to be lifted from the liquid surface at the same angle and speed, effectively extending the flow path of the adhesive under gravity and dispersing the tendency for adhesive accumulation. After the lifting is completed, the drive motor 13 starts again. Through the cooperation of the active gear disk 12 and the toothed plate 16, the moving frame 4 and the mold module are moved horizontally out of the impregnation area and into the degreasing or pre-vulcanization station to complete a complete cycle.

[0024] This equipment, through the coordinated operation of all the aforementioned structures, systematically solves the two core problems of uneven glue sedimentation and unbalanced thickness distribution in existing latex glove dipping processes, bringing multiple beneficial effects: First, the continuous stirring of the latex liquid by the stirring blade 5 and the drive module effectively prevents the sedimentation of fillers and additives, ensuring uniform glue composition and avoiding surface defects or thickness fluctuations in gloves due to local concentration differences; Second, the baffle plate 6, driven by the lifting module 7, periodically rises and falls, combined with the transmission structure of the U-shaped frame, disturbing the boundary layer of the pool wall, breaking the concentration gradient in the static area, and forming a "center + edge" dual mixing mechanism with the stirring blade 5, significantly improving the overall uniformity of the glue liquid; Third, the combination of the lifting cylinder 15, lifting plate 9, support frame 10, and guide rod 8 in the vertical lifting structure ensures that the mold module maintains a stable tilted posture during the lifting process, changing the traditional single downward flow path of the glue liquid during vertical lifting, making the glue... The film is more evenly distributed on the mold surface, effectively alleviating the problem of the glove being too thin at the top and too thick at the bottom; Fourth, the precise cooperation of the drive motor 13, the active gear disk 12, the toothed plate 16 and the mounting base 14 in the horizontal drive structure realizes the high-precision horizontal displacement of the moving frame 4 on the slide rail 11, ensuring that the mold is consistently dipped in glue each time, and improving the level of automation and the stability of the production cycle; Fifth, the fixture 2 is connected to the mounting rod 3 through the inclined connection structure composed of the connecting rod 18 and the inclined rod 17, which not only facilitates the quick assembly and disassembly of molds of different specifications, but also optimizes the dip angle through the inclined layout, enhancing the equipment's adaptability to multiple product categories; Sixth, the metal support frames set on both sides of the bottom of the dip tank 1 improve the rigidity of the whole machine structure and ensure the reliability of long-term operation; Seventh, the design of the guide rod 8 penetrating through the side frame 19 provides precise guidance for the lifting plate 9, preventing shaking or tilting during the lifting process and ensuring high repeatability of the mold dip trajectory. In summary, this invention organically integrates all components, including the impregnation tank 1, slide rail 11, moving frame 4, mounting rod 3, clamp 2, vertical lifting structure (including lifting cylinder 15, lifting plate 9), support frame 10, guide rod 8, side frame 19, horizontal drive structure (including drive motor 13, active gear disk 12, toothed plate 16, mounting base 14), stirring system (stirring blades 5 and drive module), turbulence system (turbulence plate 6), lifting module 7, U-shaped frame, and connecting structure (connecting rod 18, inclined rod 17). This achieves dynamic homogenization of latex liquid, controllable impregnation posture, precise transfer positioning, and convenient changeover operations. It significantly improves the thickness consistency, surface quality, and production efficiency of latex gloves, while reducing scrap rate and the risk of manual intervention. This provides reliable technical support for high-quality, high-efficiency, and intelligent production of latex gloves.
