Problems solved by technology

But this production method has the following three disadvantages: 1. When the circular loom weaves a circular tube-shaped braid, the production speed is very slow, usually less than ten meters per minute; 2. Each circular loom can only produce For hoses of one diameter, if you need to produce hoses of other diameters, you must use another circular loom; 3. It is necessary to compound the inner plastic film layer and the outer plastic film layer on the surface of the circular tube-shaped braid layer , the composite process is more complex
However, the hoses produced by seaming are prone to water seepage at the seams, the seams are not durable, and the diameter of the hoses is difficult to control accurately; in addition, the joints of the seams protrude from the outer circumference of the circular pipe wall and affect the overall Exterior

Embodiment 1

[0033] figure 1 , figure 2 The shown hose production equipment includes a guide roller 9, two left and right inclined rollers 6, an annular die 5, an outer forming die 1, an inner sizing die 2, an extruder 3, and upper and lower paired nip rollers; The paired nip rollers include the rubber pressure roller 41 at the top and the driving roller 42 at the bottom; the diameter of the ring die 5 is close to the diameter of the hose to be produced, and the inclination angles of the left and right oblique rollers 6 and The horizontal distance is adjustable; the extruder 3 is provided with an extruder head 31 . Inclined roller 6, circular ring die 5, outer forming die 1, inner sizing die 2, extruder head 31, and nip rolls are arranged in sequence from back to front; Figure 10 , Figure 8As shown, the cross-sectional shape of the outer molding die 1 includes two horizontal U-shaped jackets 15, 16 up and down, and the upper wing 11 of the upper U-shaped jacket 15 and the lower wing ...

Embodiment 2

[0038] figure 1 , figure 2 The shown hose production process adopts the hose production equipment of Embodiment 1, including the following steps:

[0039] (1), pull the planar and strip-shaped wall material 7 forward, and gradually make the left and right side edges of the strip-shaped wall material close together during the advancing process; wherein the wall material is first pulled to pass between the left and right two oblique rollers 6, Make the wall material 7 preliminarily bend, such as image 3 Shown; Draw the wall material again and pass through the annular die 5, make the wall material 7 bend and become nearly circular, as Figure 4 shown;

[0040] (2), pull the curved wall material 7 to move forward and pass through the outer forming die 1, so that when the wall material passes through the outer forming die, the cross section of the wall material 7 is along the fold line A 1 A 2 A 3 A 4 A 5 A 6 The indicated path collapses, as in Figure 5 shown; Figure...

Abstract

The invention relates to equipment for producing a water hose, which comprises an outer forming die, an inner last die, an extruder and nip rolls matched in pairs up and down, wherein the extruder is provided with an extruder head; the outer forming die, the inner last die, the extruder head and the nip rolls are arranged from the back to front in turn; the shape of the cross section of the outer forming die comprises two up and down horizontal U-shaped outer sleeves; the upper wing of the upper U-shaped outer sleeve and the lower wing of the lower U-shaped outer sleeve are integrated into a whole through a side plate; and the shape of the cross section of the inner last die comprises an upper horizontal transverse plate and a lower horizontal transverse plate, an upper vertical plate and a lower vertical plate. The invention also provides a process for producing the water hose. The equipment and the process can improve the speed of the water hose production, have simple and ingenious equipment structure, and easy processing technique and operation, and ensure the accurate inside diameter of the water hose.

Description

technical field [0001] The invention belongs to a production equipment and a production process of water delivery equipment, and in particular relates to a production equipment and a production process of a water belt. Background technique [0002] Hose is often used in agricultural irrigation, urban greening irrigation, aquaculture or construction, mine water delivery and other fields. Because the hose can be rolled up again after use, it is small in size, light in weight and easy to use, so it is very popular among users. [0003] There are generally two manufacturing methods for existing hoses. The first manufacturing method is to use a circular loom to weave a circular tube-shaped braided layer, and then compound the inner plastic film layer and the outer plastic layer on the surface of the circular tube-shaped braided layer. film layer. But this production method has the following three disadvantages: 1. When the circular loom weaves a circular tube-shaped braid, the p...
