Abstract
Description
Technical Field
[0001] This invention relates to the field of latex glove production equipment, specifically a dipping device for producing 730 nitrile latex gloves. Background Technology
[0002] Nitrile gloves are gloves made or coated with a protective layer to prevent oil damage. They are primarily used in factories, oil fields, and repair shops. Nitrile gloves do not contain latex protein, so they do not cause allergic reactions. They also possess antistatic, aging-resistant, and oil-resistant properties. Furthermore, nitrile gloves are designed to fit the human hand shape, offering excellent dexterity, good tensile strength and puncture resistance, high tensile strength, and excellent abrasion resistance.
[0003] In the manufacturing process of nitrile gloves, there is a dipping process, which mainly involves wetting the molded latex gloves with acid or alkali solutions to improve the tensile strength of the entire latex glove. After the dipping process is completed, the gloves need to be dried, and after drying, they need to be demolded.
[0004] In the existing technology, the latex glove dipping process generally involves transporting the latex glove, which is fitted onto a hand mold, laterally via a moving conveyor chain. During this transport, the lower end of the latex glove is immersed in the dipping tank. After dipping, the latex glove is vertically inserted into a drying chamber, where hot air ducts dry both sides of the glove. Finally, the dried glove is placed in the demolding position, and the demolding process requires manual labor.
[0005] This process has several drawbacks. First, because the latex gloves move vertically and horizontally, friction occurs between the gloves and the dipping tank before and after dipping, resulting in a large amount of dust and impurities adhering to the gloves' surfaces both before and after dipping, affecting the final product quality. Second, inside the drying chamber, due to the vertical movement and compressed air ventilation on both sides of the gloves, the gloves are easily detached from the mold under the combined effect of their own weight and air pressure, leading to insufficient drying. Third, after drying, the gloves still require manual demolding, which not only increases manpower but also reduces demolding efficiency.
[0006] In view of the problems mentioned above, the present invention aims to provide a dipping device for the production of 730 nitrile latex gloves. Summary of the Invention
[0007] The purpose of this invention is to provide a dipping device for the production of 730 nitrile latex gloves, so as to solve the problems mentioned in the background art.
[0008] To achieve the above objectives, the present invention provides the following technical solution:
[0009] A dipping apparatus for producing 730 nitrile latex gloves, the apparatus comprising:
[0010] The equipment includes an impregnation tank, a drying oven, and a demolding box. The impregnation tank is filled with impregnation liquid. The upper end of the impregnation tank faces the track and the conveyor chain. The conveyor chain is located on the upper end of the track. Mounting plates are spaced apart on the conveyor chain. A connecting shaft is provided between the mounting plates. A conveying component is movably mounted on the connecting shaft. A latex glove is provided at the lower end of the conveying component.
[0011] The drying chamber is connected to a platform and a conveyor chain. The two ends of the platform are connected to the corners of the track. The conveyor chain is positioned above the platform. A hot air hopper is located in the middle of the drying chamber, and a hot air assembly is installed inside the hot air hopper.
[0012] The demolding box contains a conveyor chain and a track. A demolding assembly is installed inside the demolding box. A baffle is provided at the corresponding position of the demolding assembly, and the lower end of the baffle is connected to the material drop chute.
[0013] As a further embodiment of the present invention: the conveying component includes a movable block, a sleeve, a rod, and a mounting platform. The movable block has a movable groove inside, through which a connecting shaft passes. A sleeve is fixedly installed at the lower end of the movable block. A rod is movably installed inside the sleeve. A slider is provided on the end portion of the upper end of the rod that extends into the sleeve. A guide wheel is installed in the middle of the rod. A mounting platform is provided at the lower end of the rod. The guide wheel is rotatably installed inside the track or on the upper surface of the platform. Pressure plates are provided on the left and right sides of the lower end of the mounting platform. A hand mold is provided at the middle position of the lower end of the mounting platform, and a latex glove is fitted on the hand mold.
[0014] As a further aspect of the present invention: the drying component includes a blower and a heating resistance wire, the number of which is two, and the blower and the heating resistance wire are distributed from top to bottom inside the hot air hopper.
[0015] As a further aspect of the present invention: the demolding assembly includes a pneumatic turntable and a high-pressure air duct. The pneumatic turntable is rotatably mounted inside the demolding box via a pin shaft in the middle. A pneumatic paddle is fixedly mounted on the outer surface of the pneumatic turntable. The high-pressure air duct is directly opposite the upper right side of the pneumatic turntable, and a baffle is directly opposite the upper left side of the pneumatic turntable. A channel is formed between the baffle and the pneumatic paddle on the outer surface of the pneumatic turntable. A latex glove installed at the lower end of the conveying assembly passes through the channel.
[0016] Compared with the prior art, the beneficial effects of the present invention are:
[0017] The dipping equipment for the production of 730 nitrile latex gloves can simultaneously perform automatic dipping, drying and demolding operations on the molded latex gloves, which greatly improves the overall production efficiency of latex gloves.
[0018] In addition, during the processing of latex gloves, as the conveyor chain drives the latex gloves through the upper part of the dipping tank, the inside of the drying chamber, and the inside of the demolding chamber, the tilt angle of the latex gloves can be adjusted in a timely manner according to processing needs by switching between the connected platform and the track. This can prevent the latex gloves from contacting the side of the dipping tank and getting dust and impurities, prevent them from falling inside the drying chamber, and easily and automatically remove the latex gloves from the set inside the demolding chamber.

Detailed Implementation
[0025] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention 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 invention and are not intended to limit the present invention.
[0026] Example
[0027] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 This invention provides a dipping device for producing 730 nitrile latex gloves, the dipping device comprising:
[0028] The impregnation tank 8, drying oven 16, and demolding box are arranged sequentially according to the production process. The impregnation tank 8 is filled with impregnation liquid. The upper end of the impregnation tank 8 is directly opposite the track 6 and the conveyor chain 1. The conveyor chain 1 is set on the upper end of the track 6 and is driven by a corresponding drive device. The drive device driving the conveyor chain 1 is existing technology and will not be further described here. Mounting plates 2 are distributed at intervals on the conveyor chain 1, and a connecting shaft 3 is provided between the mounting plates 2. A conveying component is movably mounted on the connecting shaft 3. A latex glove 7 is provided at the lower end of the conveying component.
[0029] The drying chamber 16 is connected to the platform 5 and the conveyor chain 1 inside. The two ends of the platform 5 are connected to the corners of the track 6. The conveyor chain 1 is positioned above the platform 5. A hot air hopper 17 is provided in the middle of the drying chamber 16. A hot air assembly is installed inside the hot air hopper 17.
[0030] The demolding box is connected to the conveyor chain 1 and the track 6. A demolding component is installed inside the demolding box. A baffle 20 is provided at the corresponding position of the demolding component. The lower end of the baffle 20 is connected to the material discharge chute 21.
[0031] The drive unit activates the conveyor chain 1, which sequentially passes through the upper end of the impregnation tank 8, through the interior of the drying chamber 16, and through the interior of the demolding chamber. When the conveyor chain 1 passes through the upper end of the impregnation tank 8, the latex glove 7 is immersed in the impregnation liquid injected inside the impregnation tank 8 via the conveying component. When the conveyor chain 1 passes through the interior of the drying chamber 16, the hot air component installed inside the hot air hopper 17 dries the latex glove 7 that has been impregnated by the conveyor component. After the conveyor chain 1 enters the interior of the demolding chamber, the demolding component installed thereon removes the dried latex glove 7 from the conveying component.
[0032] As the conveyor chain 1 drives the latex glove 7 through the upper end of the dipping box 8, the inside of the drying box 16, and the inside of the demolding box, the tilt angle of the latex glove 7 can be adjusted in a timely manner according to the processing requirements by switching between the connected platform 5 and the track 6.
[0033] Please see Figure 2 In one embodiment of the present invention, the conveying component includes a movable block 4, a sleeve 9, a rod 11, and a mounting platform 13. The movable block 4 has a movable groove inside, through which a connecting shaft 3 passes. The sleeve 9 is fixedly installed at the lower end of the movable block 4. The rod 11 is movably installed inside the sleeve 9. A slider 10 is provided on the end portion of the upper end of the rod 11 that extends into the sleeve 9. A guide wheel 12 is installed in the middle of the rod 11. The mounting platform 13 is provided at the lower end of the rod 11. The guide wheel 12 is rotatably installed inside the track 6 or on the upper surface of the platform 5. Pressure plates 14 are provided on the left and right sides of the lower end of the mounting platform 13. A hand mold 15 is provided at the middle position of the lower end of the mounting platform 13. A latex glove 7 is fitted on the hand mold 15.
[0034] When the conveyor chain 1 moves into the upper part of the impregnation tank 8, the guide wheel 12 rolls inside the track 6, while the hand mold 15 at the lower end of the mounting platform 13 immerses the latex glove 7 in the impregnation liquid injected inside the impregnation tank 8 to move and achieve the impregnation operation. When the conveyor chain 1 needs to enter the drying chamber 16, the track 6 and the platform 5 switch tracks, and the track 6 changes from straight to inclined. At the same time, the guide wheel 12 changes the inclination angle inside the track 6. When the guide wheel 12 changes the angle, the sleeve rod 11 pushes the slider 10 to slide inside the sleeve 9, and the installed movable block 4 changes the angle and moves inside the connecting shaft 3 through the opened movable groove. In this way, the vertically placed latex glove 7 can be changed to a horizontally placed movement displacement, which is beneficial to the subsequent drying operation.
[0035] Please see Figure 3 In one embodiment of the present invention, the drying component includes: a blower 18 and a heating resistance wire 19, the number of heating resistance wires 19 being two, and the blower 18 and the heating resistance wires 19 being distributed from top to bottom inside the hot air hopper 17.
[0036] When the conveying component carries the latex gloves 7 after they have been dipped in latex into the drying chamber 16, the power is simultaneously supplied to the blower 18 and the heating resistance wire 19. The blower 18 generates positive pressure air when it is turned on, and the heating resistance wire 19 generates heat when it is energized, which heats the air. The blower 18 then discharges the heated air through the hot air hopper 17 into the drying chamber 16, which is used to dry the latex gloves 7 that have been moved inside the drying chamber 16 with hot air.
[0037] Please see Figure 4In one embodiment of the present invention, the demolding assembly includes a pneumatic turntable 22 and a high-pressure air duct 23. The pneumatic turntable 22 is rotatably mounted inside the demolding box via a pin shaft in the middle. A pneumatic paddle is fixedly mounted on the outer surface of the pneumatic turntable 22. The upper right side of the pneumatic turntable 22 is directly opposite the high-pressure air duct 23, and the upper left side of the pneumatic turntable 22 is directly opposite the baffle 20. A channel is formed between the baffle 20 and the pneumatic paddle provided on the outer surface of the pneumatic turntable 22. A latex glove 7 installed at the lower end of the conveying assembly passes through the channel.
[0038] When the moving transmission component carries the dried latex glove 7 into the channel formed between the baffle 20 and the pneumatic paddles on the outer surface of the pneumatic turntable 22, high-pressure air is connected to the high-pressure air pipe 23. The high-pressure air blows out and generates aerodynamic force on the pneumatic turntable 22, thereby causing the pneumatic turntable 22 to rotate inside the demolding box. During the rotation of the pneumatic turntable 22, the pneumatic paddles on the outer surface of the pneumatic turntable 22 can generate friction on the outer surface of the latex glove 7. Through the combined action of the high-pressure air, the latex glove 7 fitted on the lower outer surface of the hand mold 15 can fall off. The fallen latex glove 7 falls into the material drop trough 21 and is finally collected and processed.
