AI Technical Summary
In the existing technology, when the first and second needle beds of the artificial turf machine are flocking, insufficient cylinder force leads to inaccurate reset or return to position, making it impossible to accurately change to the working position, resulting in uneven flocking and malfunctions, and reducing the quality of the finished turf.
The oil tank lateral movement mechanism, including a lateral movement motor, lead screw, nut, lateral movement guide rail and lateral movement slider, is adopted. The motor drives the oil tank and the flocking mechanism installed in the oil tank to move back and forth along the front and back of the lawnmower, ensuring that the first and second needle beds can be accurately changed to the working position, thus eliminating the need for cylinder drive.
It enables accurate switching between the first and second needle beds, avoiding inaccurate flocking and malfunctions, improving the quality of the finished turf, and features a simple structure and convenient workstation switching.

Description
Technical Field
[0001] This utility model relates to a lawn machine for producing artificial turf, specifically to the oil tank transmission structure in the lawn machine, and belongs to the field of textile equipment technology. Background Technology
[0002] The existing oil tank transmission structure of artificial turf machines typically includes a long strip-shaped first needle bed, a second needle bed, and an oil tank. The first and second needle beds are arranged parallel to each other at intervals along the front and rear direction of the turf machine. Tufting needles are installed on the bottom surface of both the first and second needle beds. The first needle bed is driven by a first needle bed drive mechanism installed in the oil tank to move up and down in the vertical direction. The second needle bed is driven by a second needle bed drive mechanism installed in the oil tank to move up and down in the vertical direction. During flocking, the first and second needle beds are driven by cylinders to perform flocking by changing their working positions along the front and rear direction of the turf machine. However, during flocking, the tufting needles experience significant lateral forces, and the cylinders often experience insufficient force. This results in inaccurate resetting or returning to their original positions when the first and second needle beds are driven by the cylinders to change positions. Consequently, it cannot be guaranteed that the first and second needle beds can accurately change to the working position for flocking, leading to inaccurate and uneven flocking on the first and second needle beds, or even flocking failures, which severely reduces the quality of the finished turf. Summary of the Invention

Several tufted needles 12 are installed on the bottom surface of the first needle bed 1 and the bottom surface of the second needle bed 2, arranged at intervals along their length. The first needle bed 1 and the second needle bed 2 are arranged parallel to each other in the front and rear directions of the turf machine. The first needle bed 1 is driven by a first drive mechanism 4 installed in the oil tank 3 to move up and down in the vertical direction. The second needle bed 2 is driven by a second drive mechanism 5 installed in the oil tank 3 to move up and down in the vertical direction. The oil tank transmission structure also includes an oil tank lateral movement mechanism that drives the oil tank 3 to reciprocate laterally in the front and rear directions of the turf machine.
