Description

Technical Field

[0001] The invention relates to the technical field of latex dipping tanks, in particular to a latex dipping tank and a latex liquid surface circulation method thereof. Background Art

[0002] The latex dipping tank is an industrial equipment for the production of latex dipped products. The mold or wet gel after the dipping coagulant is dried is immersed in the latex in the dipping tank and stays for the necessary time to achieve the required wet gel thickness.

[0003] Latex products produced by linkage production lines, such as latex balloons, latex gloves, latex condoms and latex finger cots, are equipped with long and narrow latex dipping tanks. In order to prevent the latex liquid surface from forming a skin during the dipping process and affecting the product quality, an electric stirring paddle is usually installed at one end or both sides of the dipping tank. Through the interlayer at the bottom of the dipping tank and the baffles at both ends, or through the reflux tanks on both sides of the dipping tank, the latex liquid surface in the dipping tank is driven to circulate in one direction to prevent the latex liquid surface from forming a skin. Various products such as latex medical catheters and latex thick-walled tension rings that require long-term dipping or repeated dipping with latex are suitable for being equipped with rectangular or cubic dipping tanks. Although electric stirring can also be used to drive the latex liquid surface in the dipping tank to circulate in one direction to prevent the latex liquid surface from forming a skin, continuous mechanical stirring will destroy the stability of the latex, causing small particles or clots of the latex in the dipping tank, resulting in fluctuations in product quality. Summary of the invention

[0004] 1. Technical issues to be solved

[0005] In view of the shortcomings of the prior art in which various products such as latex medical catheters and latex thick-walled tension rings that require long-term or repeated dipping in latex are equipped with rectangular or cubic dipping tanks for unidirectional circulation of latex liquid surface, the present invention provides a latex dipping tank and a latex liquid surface circulation method thereof, which solves the problem that continuous mechanical stirring will destroy the stability of the latex, causing the latex in the dipping tank to produce small particles or clots, etc., resulting in fluctuations in product quality.

[0006] (II) Technical solution

[0007] To achieve the above purpose, the present invention is implemented through the following technical scheme: a latex dipping tank, comprising a bottom plate, a front inner plate, a rear inner plate, a left inner plate and a right inner plate, wherein the bottom plate, the front inner plate, the rear inner plate, the left inner plate and the right inner plate are connected by welding, the outer surfaces of the front inner plate, the rear inner plate, the left inner plate and the right inner plate are fixedly connected with the outer plate near the top edge, a front return groove is arranged between the front inner plate and the outer plate, a left return groove is arranged between the left inner plate and the outer plate, a right return groove is arranged between the right inner plate and the outer plate, a left partition plate is fixedly connected between the rear inner plate and the outer plate and near the left edge, and a right partition plate is fixedly connected between the rear inner plate and the outer plate and near the right edge, The closed area between the left partition plate and the rear inner plate, the outer plate and the right partition plate forms a sandwich, a left return hole is opened on the surface of the left partition plate near the bottom edge, a left baffle is movably connected to the inner surface of the left partition plate near the top edge, a right return hole is opened on the surface of the right partition plate near the bottom edge, a right baffle is movably connected to the inner surface of the right partition plate near the top edge, an elliptical hole is opened on the rear surface of the outer plate, a hemispherical rubber is installed around the periphery of the elliptical hole, a plastic plate is fixedly connected to the most protruding part of the spherical surface of the hemispherical rubber, a piston rod is fixedly connected to the rear surface of the plastic plate, the piston rod is driven by a pneumatic press, and the pneumatic press is installed on the rear side of the sandwich through a support frame.

[0008] Preferably, the front reflow groove is connected to the left reflow groove and the left reflow hole, and the right reflow groove and the right reflow hole respectively.

[0009] Preferably, a strip cover is installed on the top of the interlayer, and an overflow seam is provided between the strip cover and the rear inner plate.

[0010] Preferably, the hemispherical rubber is made of rubber material, and the front inner plate is shorter than the rear inner plate, the left inner plate and the right inner plate.

[0011] A latex liquid surface circulation method for a latex dipping tank comprises the following steps:

[0012] S1: Put the filtered compound latex into the dipping tank, preferably the latex liquid level slightly submerges the front inner plate 2 of the dipping tank, the latex flows into the interlayer 9 through the front reflux groove 6, the left reflux groove 7, the right reflux groove 8, the left reflux hole 12, and the right reflux hole 14 and fills the dipping tank, and the opening of the rear interlayer 9 is covered with a strip cover 24;

[0013] S2: Start the compressed air to drive the pneumatic press 22, adjust the air pressure of the compressed air to control the pneumatic press 22 to drive the piston rod 21 to move back and forth at a frequency of 2-3 seconds each time, so that the piston rod 21 can move back and forth slowly;

[0014] S3: When the elliptical plastic plate 20 connected to the movable end of the piston rod 21 squeezes the hemispherical rubber 19, the left baffle 15 in the interlayer 9 blocks and closes the left return hole 12 on the left partition plate 11 under the action of latex pressure, and the right baffle 16 blocks and closes the right return hole 14 on the right partition plate 13 under the action of latex pressure. The latex in the interlayer 9 slowly overflows from the overflow seam 25 under the action of pressure. Because the front inner plate 2 of the immersion tank is shorter than the rear inner plate 3, the left inner plate 4 and the right inner plate 5, the latex liquid level of the immersion tank flows slowly along the rear inner plate 5 to the front inner plate 2 in one direction, and flows to the left return groove 7 through the front return groove 6. and right reflux groove 8; when the elliptical plastic plate 20 connected to the movable end of the piston rod 21 stretches the hemispherical rubber 19, the left baffle 15 in the interlayer 9 leaves the left reflux hole 12 at the lower end of the left partition plate 11 under the action of the latex negative pressure, and the left reflux hole 12 remains unobstructed, and the right baffle 16 leaves the right reflux hole 14 at the lower end of the right partition plate 13 under the action of the latex negative pressure, and the right reflux hole 14 remains unobstructed, and the latex in the left reflux groove 7 and the right reflux groove 8 flows back to the interlayer 9, and the piston rod 21 slowly moves back and forth to squeeze or stretch the hemispherical rubber 19, so as to realize the intermittent unidirectional circulation flow of the latex liquid surface in the immersion tank;

[0015] S4: When dipping latex products, the molds of some products, such as the molds of latex thick tension rings, are long strips. The direction of the mold immersed in the dipping tank must be kept consistent with the unidirectional circulation direction of the latex liquid surface to achieve the best circulation effect of the latex dipping tank liquid surface and prevent the latex liquid surface from forming a skin.

[0016] (III) Beneficial effects

[0017] The present invention provides a latex dipping tank and a latex liquid surface circulation method thereof, which have the following beneficial effects:

[0018] 1. By compressing the hemispherical rubber, the latex is squeezed to make the latex overflow through the overflow seam, and flow slowly in one direction along the rear inner plate of the immersion tank to the front inner plate, and then flow back into the rear interlayer through the front reflux groove, the left reflux groove and the left reflux hole, the right reflux groove and the right reflux hole, forming a unidirectional slow circulation flow state of the latex liquid surface in the immersion tank, so as to prevent the latex liquid surface in the immersion tank from forming a skin.

[0019] 2. It overcomes the drawbacks of mechanical stirring latex dipping tanks that the stability of latex is destroyed due to continuous mechanical stirring, resulting in small latex particles or clots, which reduce product quality. It effectively improves the quality level of products such as latex medical catheters and latex thick-walled tension rings that require long-term dipping or repeated dipping with latex.

[0020] 3. Compressed air drives the pneumatic press to promote the circulation of the liquid surface in the latex dipping tank, which is more energy-efficient than the mechanical stirring latex dipping tank to promote the circulation of the liquid surface. BRIEF DESCRIPTION OF THE DRAWINGS
