Description

Technical Field

[0001] The present technical solution belongs to the technical field of agricultural irrigation water hoses, and specifically belongs to a production method of water hoses for smart agricultural facilities and a production line thereof. Background Art

[0002] Water hoses are often used in industrial and agricultural irrigation, greening irrigation, aquaculture, firefighting and construction industries. Since water hoses can be rolled up after use, they are small in size, light in weight and easy to use, so they are very popular among users. In general, traditional water hoses are usually produced by lifting up. The plastic extruder squeezes the plastic into the water hose production mold, and then melts and extrude the plastic through the mold core of the inner mold of the plastic production mold to form the initial water hose hose wall. The problem is that the shape and quality of the product are unstable due to temperature changes during the production of the water hose, and the wall strength of the water hose hose formed directly by melting is low and there is a certain wall thickness deviation, which greatly limits the water delivery distance and water delivery strength. At the same time, it is necessary to punch holes in the water hose wall (drill installation holes) during use, and install water guide pipes at the installation hole position.

[0003] Existing pressure-resistant water hoses are generally provided with a woven layer made of plastic flat wires or yarns woven in warp and weft. The woven layer has strong tensile and crack resistance, so that the water hose can withstand greater water pressure; but due to the dense pores in the woven layer itself, in order to prevent water from seeping out from the radial direction, an inner lining plastic film layer must be compounded on the inside of the woven layer; in addition, since the surface of the woven layer is rough, it is easy to wear when it is in direct contact with the ground, so some pressure-resistant water hoses are also compounded with an outer protective plastic film layer on the outside of the woven layer.

[0004] The manufacturing process of existing pressure-resistant hoses is generally to first compound the inner lining plastic film layer, the woven layer, and the outer protective plastic film layer into a planar composite wall material, and then bend and overlap the composite wall material into a tube. The overlapped tubular composite wall material is called a tube wall. The overlapping part of the tube wall is formed by overlapping the head and tail ends of the composite wall material. The overlapped part located on the outer layer is called the outer overlapped section, and the overlapped part located on the inner layer is called the inner overlapped section. Summary of the invention

[0005] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide a method for producing a water hose for smart agricultural facilities and a production line thereof. The wall thickness is uniform and the water hose pipe wall has been punched during the production process, which is very convenient to use. Since the welding surface of the water outlet part is on the inner side of the water hose pipe wall, it is not easily worn by external factors and causes water leakage, and the product quality is stable.

[0006] In order to achieve the above-mentioned purpose, a technical solution provided by the present technical solution is: a method for producing a water hose for smart agricultural facilities and a production line thereof, characterized in that it comprises the following steps: step 1, punching holes after leveling the water hose pipe wall material;

[0007] Step 2, welding the water outlet parts on the upper surface of the punching position of the water hose pipe wall;

[0008] Step 3, bending both sides of the hose pipe wall upward and overlapping to form a hose;

[0009] Step 4: Level the hose, roll it up and pack it.

The position of the clamping hand when not pushed by the upper and lower force arms and the front and rear force arms is the initial position. The water outlet fixing bracket is arranged above the initial position of the clamping hand. The stroke of the upper and lower force arms pushing the clamping hand is the distance between the clamping hand and the water outlet fixing bracket. The position of the clamping hand at the end when it is pushed by the upper and lower force arms and the front and rear force arms is the final position. The clamping hand sends the water outlet to the final position and passes it to the welding device. The water outlet is a water guide pipe arranged at the water outlet of the water hose pipe wall. The movement of the upper and lower force arms and the front and rear force arms can be completed by a hydraulic cylinder or a pneumatic cylinder, which is common knowledge in the industry. The clamping hand can be pushed by the upper and lower force arms to stretch upward to clamp the water outlet.

[0016] Preferably, the side panels on both sides extend toward the upper surface of the rear section and a space is left between the side panels on both sides to accommodate the water hose pipe wall material pressed down by the hot pressing part.

[0017] Preferably, a gap is formed between the curved guide bottom plate and the rear section for the water supply belt pipe wall material to pass through.

[0018] Preferably, the upper surface of the curved guide bottom plate or the lower surface of the curved guide inner plate is also provided with a groove for the water outlet to pass through, so as to facilitate the water outlet to pass through the space between the curved guide bottom plate and the rear section.

[0019] Preferably, the front section is in a gradually changing shape with a wide head end and a flat thickness and a narrow tail end and a thick thickness, and the rear section is in a rectangular parallelepiped shape. The shape change of the head and tail ends of the front section can make the hose wall material change from being laid flat to being rolled up on both sides during the forward process, which is convenient for overlapping the two sides of the hose wall material in the later stage.
