Description

Material pumping pipe sleeve nozzle

Technical Field

The utility model relates to an automobile manufacturing field, more specifically say, relate to the paint coating technology in the automobile manufacturing.

Background

In the automobile manufacturing process, the paint coating process is an indispensable link. The paint coating process for automobiles generally comprises the main procedures of plate pretreatment, cathode electrophoresis coating, PVC sealing protection, middle paint spraying, colored paint spraying and wax injection protection. The materials required by the pretreatment and electrophoresis procedures are liquid dangerous chemical materials, and the packaging barrel of the dangerous chemical must be treated by a user according to the requirements of national environmental protection regulations. In order to reduce the treatment cost of the dangerous waste barrel, automobile manufacturers add a plastic lining bag in a dangerous chemical material packaging barrel, take out the plastic lining bag after the materials are used as the dangerous waste for treatment, and recycle clean empty barrels by material suppliers.

The use process and the use mode of the chemical materials in the pretreatment and electrophoresis process production processes related to the liquid dangerous chemical materials are simply introduced as follows:

the materials of the pretreatment process comprise degreasing agents, phosphating replenishers, surfactants, neutralizers, passivators and the like, and the materials of the electrophoresis process mainly comprise resins, color pastes, solvents and the like. In the production process, the addition of the technical chemical materials is automatically set, dropwise adding is carried out according to the number of vehicles, manual feeding is carried out, and the material pumping pipe needs to be inserted into a chemical material packaging barrel regardless of the feeding mode. The material of iron system and PA material is used to the pumping pipe at present conventionally, and the pumping pipe top contacts with the interior lining bag of plastics, and the mouth of pipe of pumping pipe all can direct contact interior lining bag of plastics when discontinuous and continuous pumping. To the drawing pipe of iron system or PA material, the inside lining bag of plastics can be damaged to its hard and rough mouth of pipe when the contact, then causes the liquid seepage light, then directly causes lining bag hole to wear large tracts of land weeping heavy, pollutes the pail pack inner wall, makes the pail pack can not recycle, increases dangerous chemicals pail pack treatment cost.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a cover mouth of cover on the mouth of pipe of drawing material pipe to avoid the mouth of pipe of drawing material pipe to the damage of the interior welt bag of plastics.

According to the utility model discloses an embodiment provides a pumping pipe cover mouth, and this pumping pipe cover mouth cover is at the front end of pumping pipe, and this pumping pipe cover mouth is hollow cylindrical, and the top of pumping pipe cover mouth is rolled over inwards and is formed the draw-in groove, and during the pipe wall of pumping pipe was embedded into the draw-in groove, the draw-in groove was with the pipe wall tight fit of pumping pipe, and the part that the top of pumping pipe cover mouth formed the draw-in groove was convex, and the outside is smooth.

In one embodiment, the side walls of the pumping tube nipple are tapered inwardly from top to bottom, and the pumping tube nipple is clamped onto the pumping tube.

In one embodiment, the top of the pumping pipe sleeve nozzle is provided with an auxiliary pumping groove.

In one embodiment, the auxiliary pumping groove is two crescent grooves arranged at the top of the pumping pipe sleeve nozzle.

In one embodiment, the material of the pumping pipe sleeve nozzle is polyamide.

The utility model discloses a smooth mellow and full outside of pumping pipe cover mouth is difficult to cause the damage to the interior welt bag of plastics, and the supplementary material groove of taking out of crescent is seted up on the top of this pumping pipe cover mouth, can extract the liquid in the pail pack more fully.

Drawings

The above and other features, properties and advantages of the present invention will become more apparent from the following description of the embodiments with reference to the accompanying drawings, in which like reference numerals refer to like features throughout, and in which:

fig. 1 shows a cross-sectional structure view of a drawing tube sleeve according to an embodiment of the present invention.

Fig. 2 shows a side view of a drawing tube sleeve according to an embodiment of the present invention.

Fig. 3 discloses a top view structure diagram of a pumping pipe sleeve according to an embodiment of the present invention.

Detailed Description

Referring to fig. 1 to 3, the present invention discloses a drawing pipe sleeve, wherein fig. 1 shows a cross-sectional structure of the drawing pipe sleeve, fig. 2 shows a side structure thereof, and fig. 3 shows a top structure thereof.

According to the illustrated embodiment, the pumping tube nipple 100 is at the front end of the pumping tube, and the pumping tube nipple 100 has a hollow cylindrical shape. The top end of the pumping pipe sleeve nozzle is turned inwards to form a clamping groove 101, the pipe wall of the pumping pipe is embedded into the clamping groove 101, and the clamping groove 101 is tightly matched with the pipe wall of the pumping pipe. The part of the top end 102 of the material pumping pipe sleeve nozzle, which forms the clamping groove, is arc-shaped, and the outer side is smooth. Therefore, the pumping pipe sleeve nozzle has a smooth and round outer side, and is not easy to damage a plastic lining bag when being contacted with the plastic lining bag. In the illustrated embodiment, the side walls of the withdrawal pipe nipple 100 converge inwardly from top to bottom, so that, in the configuration shown in fig. 1 and 2, the withdrawal pipe nipple 100 resembles an inverted trapezoid in cross-section and side configuration. In an actual product, the inward-inclined angle is smaller, so that the whole pumping pipe sleeve nozzle 100 is still cylindrical, and the inward-inclined angle is more obvious in order to highlight the inward-inclined characteristic of the side wall in the drawing. The inner diameter of the pumping pipe sleeve nozzle is tightly matched with the outer diameter of the pumping pipe, and the bottom of the pumping pipe sleeve nozzle can be tightly clamped on the pumping pipe under the condition that the bottom of the pumping pipe sleeve nozzle is inwards inclined so as to prevent the situation that the pumping pipe sleeve nozzle is separated in the using process.

After the material pumping pipe nipple is sleeved, the material pumping capacity of the material pumping pipe can be influenced to a certain extent, the liquid in the packaging barrel can not be completely pumped by the material pumping pipe, the part of liquid which can be pumped does not exist in the material pumping pipe, the plastic lining bag needs to be taken out, and the liquid is poured out for use. To improve the ability of the pump line to pump fluid after it is pulled over the nipple, in one embodiment, the pump line nipple 100 is topped with an auxiliary pump reservoir 103. Referring to the embodiment shown in fig. 2 and 3, the auxiliary pumping trough 103 is two crescent-shaped troughs that open at the top of the pumping pipe nipple.

In one embodiment, the material of the pumping pipe sleeve nozzle is polyamide. Polyamide materials have the following basic properties: the temperature can be kept between minus 40 ℃ and plus 80 ℃, and the product is white, nontoxic and pollution-free to pretreatment and electrophoresis tank liquid. The polyamide material does not chemically react with the chemical liquids used in the pretreatment, electrophoresis process.

The utility model discloses an installation as follows of material pumping pipe sleeve mouth: aim at the mouth of pipe of drawing material pipe with the cover mouth, pat the top of drawing material pipe into with the cover mouth, during the draw-in groove at drawing material pipe lateral wall's top embedding cover mouth top, the lateral wall chucking of cover mouth is on the lateral wall of drawing material pipe, because the lateral wall of cover mouth is by the top like bottom slightly adduction, consequently the cover mouth can firmly be chucking on drawing material pipe.
