Description

Technical Field

[0001] This utility model relates to the field of drip irrigation tape equipment technology, and in particular to a drip irrigation tape production line. Background Technology

[0002] Existing drip irrigation tape production equipment includes a dripper screening machine, an extruder system, a vacuum sizing system, a water cooling system, a traction punching system, a wire tensioning system, and a winding system, which are connected in sequence and arranged in a line.

[0003] The applicant, engaged in the research and development of drip irrigation tape equipment, applied for a Chinese invention patent on March 11, 2022, entitled "A Dripper Screening Machine," publication number: CN 114602809 B. The invention utilizes a dripper screening device where the inner disc rotates at a certain angle, and the inner side of the outer ring is arc-shaped. This ensures that when the inner disc rotates at an angle, the outer circumference of the inner disc remains equidistant from the inner wall of the outer ring, thus solving the problem of drippers getting stuck in gaps.

[0004] The applicant applied for a Chinese invention patent on June 7, 2022, entitled "A Layout Method for a Drip Irrigation Tape Production Line", publication number: CN 115027027 A. By using the dripper screening equipment as the starting equipment of the production line, and extending the guide rail along the first arm of the "U" shape, other equipment and production equipment are connected in sequence along the second arm of the "U" shape. This shortens the existing production line's planar space and solves the problem of production and use in factory buildings with a length not exceeding 30 meters.

[0005] To optimize drip irrigation tape production equipment, the applicant continued research and development, aiming to provide a new type of drip irrigation tape production line, which also uses a dripper screening machine as the first production equipment on the production line, and at the same time meets the requirements of limited factory space for drip irrigation tape production. Utility Model Content

[0006] To address the aforementioned problems, this utility model provides a drip irrigation tape production line.

[0007] The technical solution of this utility model is: a drip irrigation tape production line, including a dripper screening machine, an extruder, and a vacuum sizing device; specifically, the dripper screening machine is equipped with a double-layer dripper track, the double-layer track is arranged around the main body of the dripper screening machine, the dripper screening machine is connected to a feeding device through the outer track, the feeding device feeds the drippers into the die head of the extruder, and the plastic tubing output from the die head of the extruder is fed into the vacuum sizing device which is sequentially adjacent to it; the extruder is placed parallel to the rear side of the vacuum sizing device, and a temperature control cabinet is placed parallel to the rear side of the extruder.

[0008] Furthermore, in order to increase the number of drippers output on the drip irrigation tape production line and facilitate the operation of the drippers, the dripper track is a double layer with an inner and an outer layer, and the inner and outer tracks are tightly connected. The dripper track is in the shape of a square and surrounds the outside of the dripper screening machine.

[0009] Furthermore, the dripper screening machine is provided with two feeding ports, which are opposite each other and respectively located at the front and rear ends of the dripper screening machine. The feeding device of the dripper screening machine feeds materials through the front feeding port or the rear feeding port.

[0010] Furthermore, to facilitate temperature control, the control button panel of the temperature control cabinet is designed as a pull-out structure. By installing a pull-out device between the control button panel and the temperature control cabinet, the position of the control button panel can be moved as it is pulled out. A movable connecting rod is installed between the PLC control board and the temperature control cabinet, allowing the position and direction to be changed at any time according to the operator's convenience.

[0011] The beneficial effects of this utility model are as follows: By changing the original single-line track to a double-layer track, this utility model ensures that when the dripper screening machine jams, the number of drippers in the track is sufficient, guaranteeing uninterrupted production. Furthermore, changing the original single-line track to a double-layer track surrounding the dripper screening machine also shortens the distance between the machine and other equipment, reducing the original single-line track from six meters to one meter. This shortens the overall length of the drip irrigation tape production line, making it ideal for drip irrigation tape production in situations where factory space is limited.

[0012] Feeding ports are set at both the front and rear ends of the dripper screening machine. By setting the dripper track around the main body of the dripper screening machine, a certain space gap is created between the dripper screening machine and the extruder, which meets the space requirements of the dripper screening machine's feeding device at the rear end.

[0013] The extruder's position has been changed. Originally located behind the feeding track, it's now positioned behind the vacuum sizing device, making manual operation easier. The extruder's feeding section has also been adjusted. Previously, the feeding device was too close to the dripper screening machine, which could easily cause dripper jamming during feeding if material spillage occurred. With the extruder's new position, the feeding device is further away from the dripper screening machine, preventing the fed particles from splashing onto the track or other operating parts, ensuring the safety of the drippers and track, and reducing the likelihood of jamming.

[0014] The temperature control cabinet and the extruder are connected and placed side by side. The control panel is operated by pulling out. When the control panel is pulled out, it is convenient to operate the temperature control cabinet. When the control panel is retracted into the temperature control cabinet, it is convenient to move the temperature control cabinet. Attached Figure Description

[0018] A drip irrigation tape production line includes a dripper screening machine, an extruder, and a vacuum sizing device. The dripper screening machine is placed at the starting position of the production line as the first piece of equipment. The dripper screening machine is equipped with a dripper track consisting of inner and outer double layers, which are tightly connected. The double-layer dripper track surrounds the outside of the dripper screening machine. The dripper track is roughly square, with the intersection of the two sides of the square forming an arc. After being conveyed from the dripper screening machine to the track, the drippers are conveyed along the straight lines of the square and the arc. The drippers are approximately 2 cm long and 0.1 cm thick. The short and thin drippers are conveyed along the straight track, which reduces the likelihood of jamming, especially during high-speed transmission. The arc-shaped track facilitates the transmission of drippers along the straight track in different directions, reducing the likelihood of jamming during transmission.

[0019] Two feeding ports are set on the dripper screening machine. The two feeding ports are opposite each other and are respectively set at the front and rear of the dripper screening machine. The feeding device of the dripper screening machine feeds materials through the front feeding port or the rear feeding port.

[0020] After the double-layer track is set around the main body of the dripper screening machine, the dripper screening machine is connected to the feeding device through the outer track. The feeding rod of the feeding device extends into the extruder head and feeds the drippers into the extruder head. The plastic tubing output from the extruder head is fed into the vacuum sizing device that is adjacent to it. The extruder is placed on the rear side of the vacuum sizing device. A screen changer is set between the extruder and the extruder head. The screen changer can be a device independently developed by the applicant. The applicant applied for a Chinese patent on January 26, 2021, entitled "A Continuous Belt Screen Changing Device", with publication number CN 214562837U.

[0021] A temperature control cabinet is placed parallel to the extruder at the rear. A drawer is installed between the temperature control cabinet and the control button panel. When in use, the drawer is pulled out, allowing the control button panel to move as it is pulled out. A movable connecting rod is installed between the PLC control board on the temperature control cabinet and the cabinet itself. The position and orientation of the PLC control board can be changed at any time according to the operator's convenience.

[0022] In actual operation, the production line can choose to place the feeding device of the dripper screening machine at the front or rear end as needed. After being screened by the dripper screening machine, the drippers are conveyed to the feeding device via the inner and outer rails. The feeding device sends the drippers into the extruder head, and the plastic pipe output from the extruder head is also sent to the vacuum sizing device, which is connected in sequence. Through the connected water cooling system, traction punching system, wire tensioning system, and winding system, the production of drip irrigation tape is completed. The temperature control cabinet is placed on the rear side of the extruder. During the drip irrigation tape production process, the drawer can be opened to facilitate the operation of the control button panel, further facilitating the control of the extruder temperature and accurately controlling the temperature, time, and other parameters during production.

[0023] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
