Description

Technical Field

[0001] The present invention relates to the field of nitrile glove production, in particular to a dipping device for producing nitrile gloves. Background Art

[0002] Nitrile gloves are made from butadiene and acrylonitrile through emulsion polymerization. They offer excellent oil resistance, high abrasion resistance, and good heat resistance. Made from high-quality nitrile rubber and other additives, they are refined and processed. They contain no protein, are non-toxic, harmless, durable, and adhere well to human skin. They are widely used in household chores, electronics, chemicals, aquaculture, glass, food processing, and other factory protection, as well as in hospitals, scientific research, and other industries.

[0003] During the production of medical nitrile gloves, the hand mold first needs to be acid-washed, then washed again with water, alkaline, and other cleaning steps, and then pre-dried to prepare for latex dipping. The latex reacts with the coagulant to form a glove film, and after a subsequent drying process, the nitrile glove is formed on the surface of the glove mold. During the hand mold dipping process, the pre-mixed rubber material is added to the coagulant tank, so that the glove production line enters the rubber tank at a uniform speed along a concave arc trajectory for hand mold dipping. The rubber material in the coagulant tank will partially precipitate. To prevent the rubber material from sticking and forming sticky flocs in the coagulant tank, a stirring device is required to stir and mix it, thereby preventing material waste.

[0004] In response to the aforementioned related technologies, the inventors discovered that the rubber material in the coagulant tank generates bubbles during the stirring process. The bubbled glove solution, when formed on the hand mold, can produce a grainy feel on the glove surface, affecting the glove quality. Furthermore, during the stirring process, the stirring tool has a small area, while the solution area in the tank is large. During mixing, precipitates easily flow into other areas of the tank, preventing them from mixing properly with the solution and preventing the glove solution from circulating properly. Furthermore, after the hand mold has been dipped in the glue for a period of time, the glove solution level in the coagulant tank continuously decreases. A certain drop in the level can affect the glove's precision, necessitating replenishment of the glove solution. Manual replenishment of the glove solution is not only time-consuming and labor-intensive, but also requires constant attention to the production line's operating trajectory. In some cases, the movement of the hand mold base must be stopped, affecting the production efficiency of nitrile gloves. Summary of the Invention

[0005] The main technical problem solved by the present invention is to provide a dipping device for nitrile glove production, which can not only circulate the glove solution and promote the mixing of the precipitate, but also reduce the generation of bubbles. At the same time, it can also replenish the material in the dipping tank in time, thereby improving the production efficiency of nitrile gloves.

[0006] To solve the above technical problems, the present invention adopts a technical solution: providing a dipping device for nitrile glove production, comprising: a trough body and partition walls symmetrically installed on both sides of the inner cavity of the trough body, wherein the partition walls and the trough body respectively form a reflux cavity, the front and rear ends of the partition walls respectively form flow channels with the trough body, and an impregnation cavity is formed between the partition walls, and the bottom of the reflux cavity is provided with a downwardly concave conical guide portion;

[0007] The tank also includes a circulating stirring assembly for driving the circulation of the glove solution. The circulating stirring assembly is installed in the central area of ​​the conical guide portion. An automatic feeding pipe assembly is installed at one end of the tank body. The circulating stirring assembly includes a support plate installed above the reflux chamber. A stirring mechanism for mixing the precipitate is installed at the bottom of the support plate. A driving mechanism for driving the stirring mechanism to rotate is installed on the support plate.

[0008] The stirring mechanism includes a stirring barrel and a flange connected to the top of the support plate, the outer diameter of the stirring barrel matches the width of the reflux chamber, the stirring barrel is provided with a feed notch at the bottom end on one side close to the automatic feeding pipe assembly, and a discharge notch is provided at the top end on the other side, baffle plates are connected to the two sides of the feed notch, the outer sides of the baffle plates are respectively connected to the inner wall of the reflux chamber, a deep groove ball bearing is installed in the flange, a rotating shaft is connected to the deep groove ball bearing, and a plurality of stirring blades are installed at intervals on the bottom of the rotating shaft, and the stirring blades are arranged close to the bottom of the inner cavity of the stirring barrel;

[0009] A material blocking plate is sleeved on the outer circle of the rotating shaft, and a connecting rod is symmetrically installed on the top of the material blocking plate. The connecting rod is connected to the support plate. The material blocking plate is located below the discharge notch and above the stirring blade.

[0010] By adopting the above technical solution, the automatic feeding pipe assembly replenishes the tank in a timely manner. Simultaneously, the driving mechanism rotates the stirring mechanism, causing the glove solution to flow into the reflux chamber, while the precipitate is driven to the bottom of the tapered guide. Simultaneously, the stirring blades cause the precipitate to flow through the feed notch to the bottom of the mixing barrel, thoroughly mixing it with the solution and preventing material waste. During the stirring process, the retaining plate not only prevents the precipitate from overflowing upward but also effectively reduces the generation of bubbles. The stirred glove solution overflows through the discharge notch and circulates at a uniform rate into the immersion chamber, effectively circulating the glove solution and promoting mixing of the precipitate while also effectively reducing the generation of bubbles.

[0011] In a preferred example, the present invention can be further configured as follows: the automatic feeding tube assembly includes a drainage tube, a waist-shaped discharge port is provided on the drainage tube, a guide tube is provided at one end of the drainage tube, a rotary joint is installed at one end of the guide tube close to the drainage tube, and the other end is connected to the solution source, the rotary joint and the end of the drainage tube are connected by bolts, an adjusting cylinder is passed through the interior of the drainage tube, a waist-shaped opening matching the waist-shaped discharge port is provided on the adjusting cylinder, the open end of the adjusting cylinder is connected to the rotary joint, the closed end of the adjusting cylinder is connected to a buoyancy member that drives the adjusting cylinder to rotate, the end of the drainage tube away from the rotary joint is threadedly connected to a waterproof ring, a waterproof gasket is installed in the waterproof ring, the buoyancy member includes a sleeve rod and a float connected to the bottom thereof, the sleeve rod is located outside the drainage tube, and the waist-shaped opening and the waist-shaped discharge port are in an overlapping state when the float hangs down.

[0012] By adopting the above technical solution, after the hand mold base has been operating continuously for a period of time, the liquid level in the tank body gradually decreases, causing the float to rotate under the action of the rotary joint, driving the waist-shaped opening to move toward the waist-shaped discharge port. When the waist-shaped opening and the waist-shaped discharge port coincide with or contact each other, the glove solution flows into the tank body at a uniform speed, thereby realizing automatic feeding. When the feeding reaches the appropriate liquid level, the glove solution drives the float ball to swing upward, causing the waist-shaped opening and the waist-shaped discharge port to be misaligned, thus ending the feeding operation and improving the production efficiency of nitrile gloves.

[0013] In a preferred example, the present invention can be further configured as follows: a blocking rod is connected to the inner cavity side of the trough body close to the automatic feeding tube assembly, and the blocking rod is in contact with the sleeve rod and causes the sleeve rod to be in an inclined state.

[0014] By adopting the above technical solution, the blocking rod prevents the sleeve rod and the float from being in a vertical downward state, thereby reducing a certain pressure when the float rotates when the solution in the tank descends or rises.

[0015] In a preferred example, the present invention can be further configured as follows: the driving mechanism includes a wheel disc 1 installed at the top of the rotating shaft and a motor installed on one side of the support plate, the output shaft of the motor is connected to a wheel disc 2, the wheel disc 1 and the wheel disc 2 are connected by a belt, and a protective shell is installed on the top of the support plate, and the protective shell cover is arranged above the wheel disc 1 and the wheel disc 2.

[0016] By adopting the above technical solution, the motor drives the second wheel to rotate, so that the belt synchronously drives the first wheel to rotate, and the rotating shaft drives the stirring blades to perform stirring operations, so that the sediment is mixed with the glove solution. Under the action of the protective shell, the installation performance of the drive structure is improved.

[0017] In a preferred example, the present invention can be further configured as follows: a plurality of connecting plates 1 are connected to both sides of the support plate, a connecting plate 2 matching the connecting plate 1 is connected to the top of the mixing barrel, and the connecting plate 1 and the connecting plate 2 are connected by bolts.

[0018] By adopting the above technical solution, the connecting plate 1 and the connecting plate 2 improve the stability of the mixing barrel in the reflux chamber.

[0019] In a preferred example, the present invention can be further configured as follows: the end of the partition wall away from the automatic feeding pipe assembly is connected to a screen, the screen is installed between the partition wall and the tank body, and the screen is set obliquely.

[0020] By adopting the above technical solution, the screen filters the circulating glove solution and further eliminates bubbles mixed in the solution, thereby improving the quality of nitrile gloves.

[0021] In a preferred example, the present invention can be further configured as follows: a filter screen with an obtuse angle is installed between the partition walls, the filter screen is installed at one end of the partition wall away from the automatic feeding pipe assembly, and the bottom of the filter screen forms an obtuse angle with the bottom of the inner cavity of the trough body, and the protrusion of the filter screen is arranged toward the automatic feeding pipe assembly.

[0022] By adopting the above technical solution, the filter screen further filters the glove solution, eliminating bubbles and preventing other impurities from being mixed into the solution. At the same time, the bottom of the filter screen forms an obtuse angle with the bottom of the inner cavity of the tank, which effectively reduces the resistance of the filter screen to the flow of the glove solution.

[0023] In a preferred example, the present invention can be further configured as follows: the tops of both ends of the partition wall are respectively connected with reinforcing ribs, and the reinforcing ribs are respectively connected to the trough body.

[0024] By adopting the above technical solution, the reinforcement ribs improve the stability and firmness of the partition wall.

[0025] In a preferred example, the present invention can be further configured as follows: interval indicator marks of different colors are arranged at intervals on the spherical surface of the float.

[0026] By adopting the above technical solution, the float rises with the water level of the solution in the tank and displays interval indicator marks of different colors at different liquid level heights to remind the staff of the liquid level status of the solution in the tank at that time.

[0027] In a preferred example, the present invention can be further configured as follows: a plurality of discharge pipe openings are respectively installed below both sides of the trough body, and the discharge pipe openings are respectively located on the inclined ends of the conical guide portion and on both sides of the circulating stirring assembly.

[0028] By adopting the above technical solution, when cleaning the tank body, the cleaning liquid flows along the inclined end of the conical guide portion to the discharge pipe opening for discharge.

[0029] In summary, the present invention includes at least one of the following beneficial technical effects of the dipping equipment for producing nitrile gloves:

[0030] 1. Under the action of the conical guide, the sediment flows along the feed notch to the bottom of the mixing barrel. When the motor drives the stirring blade to rotate, the sediment is mixed with the solution. During the stirring process, the retaining plate not only prevents the sediment from overflowing upward, but also effectively reduces the generation of bubbles. The stirred glove solution overflows along the discharge notch and circulates uniformly into the impregnation chamber. At the same time, it is filtered by the screen and filter. This not only effectively circulates the glove solution and promotes sediment mixing, but also effectively reduces the generation of bubbles.

[0031] 2. Through the cooperation of the rotary joint and the float, the float swings up and down with the water level solution. When the waist-shaped opening and the waist-shaped discharge port coincide or touch, the glove solution flows into the tank at a uniform speed, thereby realizing automatic feeding. When the feeding reaches the appropriate liquid level, the glove solution drives the float to swing upward, causing the waist-shaped opening and the waist-shaped discharge port to be misaligned, ending the feeding operation and thus improving the production efficiency of nitrile gloves.

The stirring barrel 421 is provided with a feed notch 423 at the bottom end of one side close to the automatic feeding pipe assembly 50, and a discharge notch is provided at the top end of the other side. The opening 424 and the two sides of the feed notch 423 are respectively connected with a baffle plate 425, the outer sides of the baffle plate 425 are respectively connected to the inner wall of the reflux cavity, a deep groove ball bearing 426 is installed in the flange 422, and a rotating shaft 427 is connected in the deep groove ball bearing 426, and a plurality of stirring blades 428 are installed at intervals at the bottom of the rotating shaft 427, and the stirring blades 428 are arranged near the bottom of the inner cavity of the mixing barrel 421, and a baffle plate 429 is sleeved on the outer circle of the rotating shaft 427, and a connecting rod 429a is symmetrically installed on the top of the baffle plate 429, and the connecting rod 429a is connected to the support plate 41. The baffle plate 429 is located below the discharge notch 424 and above the stirring blade 428.

[0050] Furthermore, the outer diameter of the stirring barrel 421 is adapted to the width of the reflux chamber, and the position where the stirring barrel 421 contacts the inner wall of the reflux chamber can be connected by welding. At the same time, the distance between the baffle plates 425 is the length of the feed notch 423, and the baffle plates 425 are respectively fitted with the inner wall of the reflux chamber, which can not only prevent the sediment in the glove solution from accumulating at the angle between the stirring barrel 421 and the reflux chamber, but also play a diversion role. At the same time, the length of the discharge notch 424 is the same as that of the feed notch 423. The stirring blades 428 are plate-shaped, preferably 6 in number, which can not only improve the mixing efficiency of the glove solution and the sediment, but also enable the glove solution to circulate quickly.

[0051] Example 2

[0052] like Figure 1 、 Figure 3 、 Figure 5 As shown, based on Example 1, the present invention provides a technical solution: preferably, the driving mechanism 43 includes a wheel disc 1 431 installed at the top of the rotating shaft 427 and a motor 432 installed on one side of the support plate 41, and the output shaft of the motor 432 is connected to the wheel disc 2 433, and the wheel disc 1 431 and the wheel disc 2 433 are connected by a belt. A protective shell 434 is installed on the top of the support plate 41, and the protective shell 434 cover is arranged above the wheel disc 1 431 and the wheel disc 2 433; the wheel disc 1 431 and the wheel disc 2 433 respectively have two annular mounting grooves for mounting belts, and the belts are preferably two. The motor 432 is preferably a reduction motor, which drives the wheel disc 2 433 to rotate under the action of the motor 432, and at the same time transfers the mechanical potential energy to the wheel disc 1 431 under the action of the belt, thereby driving the stirring blade 428 to rotate and stir through the rotating shaft 427.

[0053] Example 3

[0054] like Figure 1 、 Figure 4 、 Figure 6 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, the automatic feeding tube assembly 50 includes a drainage tube 51, a waist-shaped discharge port 52 is provided on the drainage tube 51, a guide tube 53 is provided at one end of the drainage tube 51, a rotary joint 54 is installed at one end of the guide tube 53 close to the drainage tube 51, and the other end is connected to the solution source, the rotary joint 54 is connected to the end of the drainage tube 51 by bolts, an adjusting cylinder 55 is passed through the interior of the drainage tube 51, and a waist-shaped opening 56 matching the waist-shaped discharge port 52 is provided on the adjusting cylinder 55, and the open end of the adjusting cylinder 55 is connected to the solution source. The rotary joint 54 is connected, and the closed end of the adjusting cylinder 55 is connected to a buoyancy member 57 that drives the adjusting cylinder 55 to rotate. The end of the drainage tube 51 away from the rotary joint 54 is threadedly connected to a waterproof ring 58, and a waterproof gasket 59 is installed in the waterproof ring 58. The buoyancy member 57 includes a sleeve rod 571 and a float 572 connected to the bottom thereof. The sleeve rod 571 is located outside the drainage tube 51. When the float 572 hangs down, the waist-shaped mouth 56 and the waist-shaped discharge port 52 are in a coincident state. The side of the inner cavity of the trough body 1 close to the automatic feeding pipe assembly 50 is connected to a baffle rod 6, and the baffle rod 6 is in contact with the sleeve rod 571 and The sleeve rod 571 is tilted, and the surface of the float 572 is spaced with interval indicator marks 573 of different colors. The drainage tube 51 is a stainless steel pipe with a flange interface at one end, so that its connecting end is connected to the rotary joint 54 via bolts. At the same time, a solenoid valve can be installed on the end of the guide tube 53 away from the rotary joint 54 to control the pressure of the solution discharge. It should be noted that the buoyancy of the glove solution is much greater than the gravity of the float 572, so that the float 572 can float on the surface of the glove solution by swinging. After the hand mold base continues to operate on the production line for a period of time, The liquid level in the tank body 1 gradually decreases. At this time, the float 572 rotates and swings under the action of the rotary joint 54, driving the waist-shaped opening 56 to move toward the waist-shaped discharge port 52. When the waist-shaped opening 56 coincides with or contacts the waist-shaped discharge port 52, the glove solution flows into the tank body 1 at a uniform speed, thereby realizing automatic feeding. When the feeding reaches the appropriate liquid level, the glove solution drives the float 572 to swing upward, causing the waist-shaped opening 56 and the waist-shaped discharge port 52 to be misaligned, completing the feeding operation. At this point, the water level is at the appropriate position for dipping the hand mold base, thereby improving the production efficiency of nitrile gloves.

[0055] The following is a detailed description of the working principle of the dipping equipment for the production of nitrile gloves.

[0056] like Figure 1-6As shown, when there is no solution in the tank body 1, the waist-shaped opening 56 and the waist-shaped discharge port 52 coincide with each other, and the guide pipe 53 transfers the glove solution prepared externally into the tank body 1. As the water level in the tank body 1 continues to rise, the float 572 swings upward under the action of the sleeve rod 571 and the rotary joint 54. Since the blocking rod 6 tilts the float 572, the pressure at the start of the float 572's rotation and swinging can be reduced when the solution in the tank body 1 rises. When the waist-shaped opening 56 and the waist-shaped discharge port 52 are misaligned, the feeding is stopped. In addition, when the hand mold production line moves into the tank body 1, the motor 432 drives the wheel 1 431 to rotate through the wheel 2 433, causing the stirring blade 428 to rotate. , one stirring blade 428 rotates clockwise, and the other stirring blade 428 rotates counterclockwise, so that the solution flows into the reflux chamber through the flow channel respectively, and under the action of the conical guide part 3, the solution containing the precipitate flows to the feed notch 423. At this time, the stirring blade 428 rotates to mix the precipitate with the solution. During stirring, the material blocking plate 429 prevents the precipitate from overflowing upward and reduces the generation of bubbles, so that the precipitate is fully mixed and overflows along the discharge notch 424 after stirring. Then, it is filtered one by one through the screen 7 and the filter 8, which effectively reduces the generation of bubbles. The latex reacts with the coagulant to form a glove film that adheres to the hand mold base and enters the subsequent processing operation in sequence.

[0057] The above are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
