Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 A double-needle collaborative weaving device for a terry cloth mixed weaving machine includes a processing table 1. Multiple support legs 2 are fixedly installed on the bottom wall of the processing table 1. Each support leg 2 has a shock-absorbing pad 3 fixedly installed on its bottom wall. Each shock-absorbing pad 3 is made of rubber, which has good elasticity and shock absorption performance. The shock-absorbing pad 3 can absorb the vibration generated during the operation of the device, reduce noise, and prevent vibration from affecting the weaving accuracy, thus extending the service life of the device. Sliding blocks 4 are slidably installed on the upper surface of the processing table 1 via two electric slide rails. A mounting plate 5 is fixedly installed on the upper surface of the two sliding blocks 4. A double-headed screw 7 is rotatably mounted on the upper end face of plate 5 via a movable frame 6. A motor 8 connected to the double-headed screw 7 is fixedly mounted on the outer wall of the movable frame 6. Two movable sleeves 10 are threadedly mounted on the outer wall of the double-headed screw 7 via a limiting mechanism. The limiting mechanism includes a limiting rod 9 fixedly installed inside the movable frame 6. The limiting rod 9 slides through the two movable sleeves 10. The sliding cooperation between the limiting rod 9 and the movable sleeves 10 can effectively prevent the movable sleeves 10 from rotating with the double-headed screw 7, ensuring that the movable sleeves 10 only move in a straight line along the axial direction of the double-headed screw 7, thereby improving the stability and accuracy of the movement of the movable sleeves 10.

[0023] Both movable sleeves 10 have knitting needles 12 fixedly installed on their bottom walls via a lifting mechanism. The lifting mechanism includes a cylinder 11 fixedly installed on the bottom wall of the movable sleeve 10. The telescopic end of the cylinder 11 is fixedly connected to the upper end face of the knitting needle 12. The upper end face of the mounting plate 5 has a movable opening that cooperates with the cylinder 11. The movable opening provides space for the cylinder 11 to move with the movable sleeve 10, avoiding interference between the cylinder 11 and the mounting plate 5, and ensuring the coordination of the movement of each component of the device. A fan 14 is fixedly installed on the outer wall of the movable frame 6 via a support mechanism. The support mechanism includes a support plate 13 fixedly installed on the outer wall of the movable frame 6. The fan 14 is fixedly installed on the upper end face of the support plate 13. The support plate 13 is made of high-strength material and has sufficient load-bearing capacity to stably support the fan 14 at a suitable height, so that the dust collection and exhaust effect of the fan 14 reaches the best.

[0024] A dust collection hood 15 is fixedly installed on the outer wall of the inlet pipe of the fan 14. A dust collection bag 17 is slidably installed on the outer wall of the outlet pipe of the fan 14 through a connecting sleeve 16. A fixing pin 18 is slidably installed through the outer wall of the connecting sleeve 16. An insertion hole for the fixing pin 18 is opened on the outer wall of the dust collection bag 17. A lever 19 is fixedly installed at the end of the fixing pin 18. The bottom wall of the lever 19 is connected to the outer wall of the connecting sleeve 16 through a fixing mechanism. The fixing mechanism includes a fixing spring 20 installed on the outer wall of the fixing pin 18. The two ends of the fixing spring 20 are elastically connected to the bottom wall of the lever 19 and the outer wall of the connecting sleeve 16, respectively. The fixing spring 20 is always in a stretched state, generating a pulling force on the lever 19, so that the fixing pin 18 is tightly inserted into the insertion hole. When it is necessary to remove the dust collection bag 17, the lever 19 is pulled to compress the fixing spring 20. The operation is simple and quick.

[0025] In use, this utility model controls the movement of the electric slide rail driven slider 4 and mounting plate 5 to adjust the knitting position. At the same time, the motor 8 is started, and its output shaft drives the double-headed screw 7 to rotate. Under the guidance of the limiting rod 9, the two moving sleeves 10 move towards or away from each other along the axial direction of the double-headed screw 7, thereby synchronously adjusting the lateral spacing of the double knitting needles 12 to adapt to the needle spacing requirements of different knitting processes. During the knitting process, the telescopic end of the cylinder 11 drives the knitting needles 12 to perform vertical lifting and lowering movements, which, together with the yarn feeding mechanism, completes the alternating knitting action of loops and pile. The moving opening on the mounting plate 5 provides sufficient space for the lateral movement of the cylinder 11, ensuring the continuity of the knitting action.

[0026] Meanwhile, the fan 14 is fixed to the outside of the moving frame 6 by the support plate 13. The dust suction hood 15 at its inlet continuously absorbs the lint and debris generated during the weaving process. After being pressurized by the fan 14, the lint and debris are discharged into the dust bag 17 through the outlet pipe. When the dust bag 17 needs to be cleaned, the operator pulls the lever 19 to make the fixing pin 18 overcome the elastic force of the fixing spring 20 and exit the insertion hole, so that the dust bag 17 can be quickly removed. After cleaning, the connecting sleeve 16 is reinserted. The rebound force of the fixing spring 20 makes the fixing pin 18 lock again, ensuring the sealing of the dust removal system. The rubber shock-absorbing pad 3 at the bottom of the support leg 2 effectively buffers the vibration generated during the operation of the equipment, reduces noise pollution, and extends the service life of each component.

[0027] Through integrated management of the external control system, the displacement of the electric slide rail, the speed and direction of the motor 8, the extension and retraction frequency of the cylinder 11, and the air volume of the fan 14 can be precisely controlled to achieve multi-parameter linkage control. When it is necessary to switch the weaving pattern, the system automatically adjusts the lateral spacing, lifting height and movement trajectory of the double weaving needles 12, and coordinates with the yarn feeding rhythm of the yarn feeding mechanism to achieve efficient weaving of complex patterns. Through the coordinated work of various components, this device significantly improves the automation level and product quality of carpet weaving, reduces the cost of manual intervention, and has broad market application value.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
