[0002] Due to the particularity of the fastener thread rod industry, which is generally small, scattered, and mixed, as well as the characteristics and difficulties of the thread rod packaging process, various manufacturers have put forward more diverse requirements for thread rod packaging equipment; currently, the industry mainly adopts manual material sorting, bundling and film wrapping, and manual winding of woven film for packaging.

[0003] There are many shortcomings in manual winding woven film packaging: 1) When manually winding the material sleeve, the burrs on the thread of the tooth bar are sharp and can easily hurt your hands.

[0004] 2) The bundled tooth bars in the industry generally weigh 15-30 kg, and manual packaging is very labor-intensive.

[0005] 3) The packaging of tooth bars is divided into too many steps, and manual packaging is inefficient and consumes a lot of manpower.

[0006] 4) The turnover rate of the packaging workers who have been engaged in strip material wrapping for a long time is high.

[0007] Therefore, in order to address the above-mentioned problems of manual winding of braided film, the burrs on the tooth bar threads can easily hurt the hands, the heavy weight of bundled tooth bars leads to high labor intensity, the multi-step operation results in low efficiency and high labor demand, and the high-intensity operation leads to high personnel mobility, resulting in low processing efficiency, high cost, unstable quality and safety hazards, a fully automatic tooth bar automatic packaging line can be designed. Summary of the Invention

Compared with manual film packaging, the packaging speed is fast, the quality is good, the packaging appearance is neat and beautiful, and it effectively protects the tooth rods from external contamination and damage during transportation and storage, thereby increasing the added value of the product. The lifting manipulator can accurately grasp and carry the sleeved tooth bar, replacing manual operation. It has accurate positioning and flexible movements, avoids the instability and labor intensity of manual handling, improves handling efficiency and accuracy, and reduces the risk of tooth bar falling or damage. The braided film wrapping machine is used in conjunction with a material distribution fork, a material rack, a driving chuck, and a film roll trolley to automatically wrap the braided film around the tooth strip. The alternating operation of the two workstations greatly improves the winding efficiency, and the machine automatically places the film, moves, cuts, and sticks the tape. Compared with manual winding, the winding effect is uniform and tight, and the packaging quality is high. At the same time, it reduces the time and intensity of manual operation and reduces labor costs. BRIEF DESCRIPTION OF THE DRAWINGS
