[0019] In order to describe the technical content, structural features, achieved purposes and effects of the application in detail, the technical solutions in the embodiments of the application will be described below in conjunction with the drawings in the embodiments of the application. Obviously, the described embodiments are only a part of the embodiments of the application, rather than all of the embodiments. In the following description, for the purpose of explanation, many specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in the case of one or more equivalent arrangements. In addition, various exemplary embodiments may be different, but are not necessarily exclusive. For example, without departing from the inventive concept, the specific shape, structure and characteristics of the exemplary embodiment may be used or implemented in another exemplary embodiment.

[0020] An embodiment of the present application provides a drip irrigation tape production line, which manufactures plastic sheets into drip irrigation tapes with a high degree of automation and high production efficiency.

[0021] like Figure 1 As shown, the drip irrigation tape production line includes: an unwinding mechanism 1, a punching machine 2, a heating and pressing mechanism 3, a cooling mechanism 4, a material storage mechanism 5 and a winding mechanism 6 arranged in sequence from upstream to downstream.

[0022] like Figure 1 、 2 As shown, the unwinding mechanism 1 includes one or more unwinding stations 11, each of which is equipped with an unwinding air shaft 12. The unwinding air shaft 12 can rotate around its own axis in the corresponding unwinding station 11 to unwind the plastic sheet to the downstream punching machine 2.

[0023] The punching machine 2 is a laser punching machine, which can project multiple laser beams onto the plastic sheet. The multiple laser beams can open multiple drip irrigation holes on the plastic sheet.

[0024] like Figure 2 、 3As shown, the heating and pressing mechanism 3 is located downstream of the punching machine 2 and is used to heat and press the punched plastic sheets together to form a drip irrigation tape. The heating and pressing mechanism 3 includes a preheating box 31, a hot oven 32, and a pressing assembly 33. The preheating box 31 is located upstream of the hot oven 32 and preheats the plastic sheets to achieve the purpose of preheating. The hot oven 32 is equipped with a fan 321 and a heating component. The heating component is located at the air outlet of the fan 321, allowing the heated air to enter the hot oven 32 and further heat the preheated plastic sheets. The pressing assembly 33 is located at the end of the hot oven 32 away from the preheating box 31 and is used to press the fully heated plastic sheets together to form the drip irrigation tape. The preheating box 31 preheats the plastic sheets upstream of the hot oven 32, shortening the heating time and improving the heating efficiency.

[0025] like Figure 2 、 4 As shown, the cooling mechanism 4 is positioned downstream of the heating and laminating mechanism 3 to rapidly cool the drip irrigation tape after hot lamination, thereby quickly shaping the tape and facilitating subsequent winding. The cooling mechanism 4 comprises a plurality of cooling rollers 41 and a water cooling tank (not shown) in fluid communication with the cooling rollers 41. The cooling rollers 41 are arranged alternately from upstream to downstream. When the drip irrigation tape passes through the cooling mechanism 4, it passes over the cooling rollers 41 in sequence, flowing from upstream to downstream, and is cooled and formed by the cooling rollers 41, which circulate cooling water internally. A water circuit is formed between the water cooling tank and the cooling rollers 41, continuously supplying cooling water to each cooling roller 41. The water cooling tank also receives hot water from the cooling rollers 41, cools the hot water into cooling water, and then circulates it back into the cooling rollers 41.

[0026] A first traction machine 7 is further installed between the heating and pressing mechanism 3 and the cooling mechanism 4 . The first traction machine 7 is used to pull the pressed drip irrigation tape into the cooling mechanism 4 .

[0027] like Figure 2 、 5 As shown, the storage mechanism 5 includes a frame 51 and a plurality of storage rollers 52. The plurality of storage rollers 52 are alternately mounted on the frame 51 from upstream to downstream. In the embodiment of the present application, each storage roller 52 is rotatably mounted on the frame 51 around its own axis, and the lower storage roller 52 is movable in the up-down direction relative to the frame 51. The drip irrigation tape passes around the plurality of storage rollers 52 in sequence from upstream to downstream. When the storage mechanism 5 stores the drip irrigation tape, the upper storage roller 52 moves upward and the lower storage roller 52 moves downward, thereby increasing the movement path of the drip irrigation tape in the storage mechanism 5 and achieving temporary storage of the drip irrigation tape. When the storage mechanism 5 discharges the drip irrigation tape, the upper storage roller 52 moves downward and the lower storage roller 52 moves upward, thereby reducing the movement path of the drip irrigation tape in the storage mechanism 5 and completing the release of the drip irrigation tape.

[0028] The winding mechanism 6 includes one or more winding stations 61, each equipped with a winding air shaft 62. A pair of winding limit disks 63 are provided on the winding air shaft 62. The pair of winding limit disks 63 are coaxially disposed on the winding air shaft 62 and spaced apart along the winding air shaft 62. Each winding air shaft 62 is rotatably mounted on the corresponding winding station 61 about its own axis. When the winding air shaft 62 rotates to rewind, the drip irrigation tape is wound between the pair of winding limit disks 63. The pair of winding limit disks 63 guide and limit the winding of the drip irrigation tape, ensuring a neat and beautiful wound surface.

[0029] When the winding mechanism 6 is changing the roll, the storage mechanism 5 temporarily stores the delivered drip irrigation tape upstream of the winding mechanism 6, so as to facilitate online roll changing of the drip irrigation tape production line and improve the winding efficiency.

[0030] A trimming device 8 and a second tractor 9 are provided between the cooling mechanism 4 and the accumulator 5. The trimming device 8 is positioned downstream of the cooling mechanism 4, with a second tractor 9 positioned upstream and downstream of the trimming device 8. The trimming device 8 is used to trim the edges of the drip irrigation tape after cooling and forming, aligning the edges and improving product quality and aesthetics. The second tractor 9 upstream of the trimming device 8 pulls the drip irrigation tape from the cooling mechanism 4 to the trimming device 8. The second tractor 9 downstream of the trimming device 8 pulls the drip irrigation tape from the trimming device 8 to the accumulator 5. The first tractor 7 and the second tractor 9 pull the drip irrigation tape within the drip irrigation tape production line, transporting it from upstream to downstream.

[0031] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments. The above embodiments and descriptions are only for illustrative purposes. Various changes and improvements may be made to the present application without departing from the spirit and scope of the present application. The scope of protection claimed in the present application is defined by the appended claims, the description and their equivalents.
