The overall mechanism is prone to unstable warp feeding during operation, which reduces operating efficiency and warp feeding accuracy, and cannot meet the requirements of high-quality plastic woven fabric production for warp feeding adjustment.

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0023] Reference Figure 1-4This utility model discloses an active warp feeding mechanism for a plastic woven fabric loom, comprising: a mounting plate 1, a wire assembly, and a sliding groove 2 on the front surface of the mounting plate 1, providing a sliding track for a mounting sliding block 13, allowing the warp feeding components to move stably along the groove. The warp feeding position is adjusted in conjunction with an external controller. A limiting sliding column 12 is fixedly connected to the inner surface of the sliding groove 2, limiting the sliding direction of the mounting sliding block 13 and preventing it from deviating during sliding, thus ensuring the stability of the movement of the warp feeding positioning column 16 and the warp feeding roller 17. A hydraulic pump 14 is fixedly connected to the rear surface of the mounting plate 1, serving as a power source. Under the control of the external controller, it provides hydraulic power to drive the hydraulic rod 15 to extend and retract, thereby driving the warp feeding components to move. The output end of the hydraulic pump 14 is fixedly connected to the hydraulic rod 15, converting the hydraulic energy of the hydraulic pump 14 into mechanical energy, which, through extension and retraction, drives the mounting sliding block 13. The sliding block 13 moves within the sliding groove 2 to adjust the position of the warp feed roller 17. The upper surface of the hydraulic rod 15 is fixedly connected to the sliding block 13, which connects the hydraulic rod 15 to the warp feed positioning column 16. Driven by the hydraulic rod 15, the roller slides along the sliding groove 2 and the limiting sliding column 12, thereby adjusting the position of the warp feed roller 17 to meet the warp feed requirements. The front surface of the sliding block 13 is fixedly connected to the warp feed positioning column 16, providing a rotation support point for the warp feed roller 17. As the sliding block 13 moves, it drives the warp feed roller 17 to move synchronously, ensuring that the warp feed roller 17 maintains a proper contact state with the warp thread 11. The outer surface of the warp feed positioning column 16 is rotatably connected to the warp feed roller 17, which rotates under the support of the warp feed positioning column 16, smoothly conveying the warp thread 11 to the subsequent process. Its position can be adjusted by moving the sliding block 13, and the amount of warp feed can be precisely controlled in conjunction with an external controller.
[0024] The interior of the sliding groove 2 is connected to the rear surface of the mounting plate 1, allowing the mounting sliding block 13 to enter the sliding groove 2 from the rear surface of the mounting plate 1 through the connection. This also facilitates the connection and power transmission between the hydraulic rod 15 and the mounting sliding block 13. The hydraulic pump 14 is located at the bottom of the rear surface of the mounting plate 1, providing stable support and sufficient extension space for the hydraulic rod 15 to ensure smooth movement of the mounting sliding block 13 within the sliding groove 2. The mounting sliding block 13, located inside the sliding groove 2, can slide along the trajectory of the sliding groove 2, adjusting the position of the warp feed positioning column 16 and the warp feed roller 17 to adapt to positional changes during the warp thread 11 conveying process. The interior of the mounting sliding block 13 is slidably connected to the limiting slide column 12. Under the constraint of the limiting slide column 12, the mounting sliding block... 13 can only slide in a straight line to avoid wobbling or deviation during movement, ensuring the accuracy of the warp feed roller 17's position adjustment. The wire guide assembly includes a tension rotating column 3, a tension roller 4, a tension rotating motor 5, a friction rotating column 7, a first friction roller 6, a friction rotating motor 8, a friction positioning column 9, a second friction roller 10, a mounting column 18, a pressure sensing roller 19, and warp threads 11. These components cooperate with each other, and under the control of an external controller, realize the conveying, tension adjustment, friction drive, and pressure sensing of the warp threads 11, jointly ensuring the stability of the warp feed process. Tension rotating motors 5 and 8 are fixedly connected to the left and right sides of the rear surface of the mounting plate 1, respectively, providing power for the rotation of the tension roller 4 and the first friction roller 6. Their positional distribution makes power transmission more rational and coordinated. An external controller controls the rotation speed to adjust the state of the warp yarn 11. A tension rotating column 3 is fixedly connected to the output end of the tension rotating motor 5, transmitting the motor's power to the tension roller 4, causing it to rotate. This column also serves as a support structure for the tension roller 4, ensuring its stable rotation to adjust the tension of the warp yarn 11. The tension roller 4 is fixedly connected to the outer surface of the tension rotating column 3, rotating under the drive of the tension rotating motor 5, contacting the warp yarn 11, and adjusting the tension of the warp yarn 11 by changing its rotation speed, thus providing warp yarn 11 with suitable tension for subsequent warp feeding processes. A friction rotating column 7 is fixedly connected to the output end of the friction rotating motor 8, transmitting the motor's power to the first friction roller 6, causing it to rotate. This column also serves as a support for the first friction roller 6, ensuring it cooperates with the second friction roller 10 to form a stable... A friction drive mechanism is used. A first friction roller 6 is fixedly connected to the outer surface of the friction rotating column 7. Driven by a friction rotating motor 8, it rotates and, in conjunction with a second friction roller 10, generates friction on the warp yarn 11, driving it forward. An external controller controls the conveying speed. A friction positioning column 9 is provided on one side of the friction rotating column 7 to provide fixed support for the second friction roller 10, maintaining a suitable distance between it and the first friction roller 6, forming a stable friction pair to drive the warp yarn 11. The outer surface of the friction positioning column 9 is rotatably connected to the second friction roller 10, which rotates on the friction positioning column 9 and, in conjunction with the first friction roller 6, clamps the warp yarn 11, using friction to drive the warp yarn 11 to move, enhancing the conveying power of the warp yarn 11. Mounting columns 18 are provided on both the left and right sides of the warp feed roller 17.A fixed mounting position is provided for the pressure sensing roller 19 to ensure stable installation and sensing of the pressure of the warp 11. The pressure sensing roller 19 is rotatably connected to the outer surface of the mounting column 18, contacting the warp 11. It senses the pressure on the warp 11 and transmits the signal to an external controller, allowing the controller to adjust the status of relevant components based on the pressure. The warp 11 is positioned between the two pressure sensing rollers 19, and the warp 11 is conveyed through the coordinated action of the rollers. The pressure sensing roller 19 can monitor pressure changes during the conveying process, providing a basis for warp feeding control.
[0025] The friction rotating column 7 and the friction positioning column 9 are positioned parallel to each other, keeping the first friction roller 6 and the second friction roller 10 parallel. This ensures uniform clamping force on the warp 11 and stable conveying. Both the friction rotating column 7 and the tension rotating column 3 extend to the front surface of the mounting plate 1, allowing the first friction roller 6 and the tension roller 4 to extend to the front surface of the mounting plate 1 and contact the warp 11, achieving frictional drive and tension adjustment of the warp 11. The rear surface of the friction positioning column 9 is fixedly connected to the mounting plate 1, stably fixing the second friction roller 10 on the mounting plate 1, maintaining a relatively fixed positional relationship with the first friction roller 6, ensuring frictional stability. The friction drive effect is stable. The outer surface of the warp feed roller 17 is rotatably connected to the warp 11. The warp 11 is smoothly fed out by rotation. Its position can be adjusted to adapt to the conveying path of the warp 11, ensuring smooth warp feeding. The pressure sensing roller 19 is located below the tension roller 4. It can sense the pressure of the warp 11 in time after the tension roller 4 adjusts the tension. This allows the external controller to adjust the state of the tension roller 4 according to the pressure change. The sliding groove 2 is located between the tension roller 4 and the first friction roller 6, allowing the warp feed roller 17 to adjust its position between the two. This better connects the warp 11 after tension adjustment to the friction drive area, ensuring the continuity of the warp feeding process.
[0026] Working principle: First, the external controller starts the equipment. The warp yarn 11 passes sequentially through the tension roller 4, pressure sensing roller 19, warp feed roller 17, and between the first friction roller 6 and the second friction roller 10. Initially, the tension rotation motor 5 starts under the controller's control, driving the tension roller 4 to rotate via the tension rotation column 3, adjusting the tension of the warp yarn 11 to maintain appropriate tension for subsequent stages. Next, the pressure sensing roller 19 contacts the warp yarn 11, sensing the pressure on the warp yarn 11 in real time and transmitting the signal to the external controller. The controller adjusts the speed of the tension rotation motor 5 based on the pressure data, further optimizing the tension of the warp yarn 11. The hydraulic pump 14 operates under the controller's command, driving the hydraulic rod 15 to extend and retract, causing the mounting sliding block 13 to slide along the limiting sliding column 12 within the sliding groove 2, thereby adjusting the tension. The positions of the warp feed positioning column 16 and the warp feed roller 17 ensure good contact between the warp feed roller 17 and the warp 11, guaranteeing smooth delivery of the warp 11. The warp feed roller 17 rotates on the warp feed positioning column 16, delivering the warp 11, which has undergone tension adjustment, towards the first friction roller 6 and the second friction roller 10. Subsequently, the friction rotation motor 8 starts, driving the first friction roller 6 to rotate via the friction rotation column 7. This rotation, in conjunction with the second friction roller 10 on the friction positioning column 9, uses friction to drive the warp 11 to continue forward delivery. The external controller adjusts the delivery speed of the warp 11 by controlling the rotation speed of the friction rotation motor 8. During this process, the sliding groove is located between the tension roller 4 and the first friction roller 6. The position adjustment of the warp feed roller 17 better connects the two, ensuring a continuous warp delivery process and ultimately completing the active warp delivery operation of the warp 11.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
