Description

Technical Field

[0001] This application relates to the field of yarn processing technology, specifically to a swing arm assembly for fancy yarn processing. Background Technology

[0002] Textiles are an ancient and important craft and technology that processes fibrous materials into fabrics and textiles through a series of processes such as spinning, weaving, and dyeing. This process involves not only complex mechanical operations and chemical treatments but also rich cultural and artistic value. From hand weaving to modern mechanized production, textile technology has been constantly innovating, which has not only improved production efficiency but also greatly enriched the types and uses of textiles. Today, the textile industry has become an important part of the global economy, providing people with a variety of products such as clothing, home decoration, and industrial products. At the same time, it faces new challenges and opportunities in the fields of sustainable development and environmental protection.

[0003] Existing patent (publication number: CN216711243U) discloses a single-spindle swing arm suction nozzle structure, including a base plate, a guide block at the top of the base plate, a tray pusher plate above the base plate, a yarn magazine above the tray pusher plate, and a lifting swing arm cylinder on one side of the top of the base plate. A suction nozzle swing arm is fixedly connected to one end of the top of the lifting swing arm cylinder. The single-spindle swing arm suction nozzle structure provided by this utility model uses negative pressure in a negative pressure hose to suck out the yarn end from inside the yarn tube. Then, the lifting swing arm cylinder returns to its initial position according to its original action. After the yarn end is pulled by the negative pressure suction nozzle, the yarn magazine enters the next production process. This allows for timely removal of the sucked-out yarn end. Furthermore, while current tail-end locating methods involve grabbing the yarn end as it falls, this solution can pre-capture the yarn end before it falls from the previous yarn tube, efficiently addressing the yarn end entanglement problem. This increases the success rate of single-spindle suction nozzle locating, reduces yarn entanglement in the yarn magazine, reduces maintenance costs, and increases production capacity.

[0004] However, when making fancy yarn, because the fine yarn itself is small and there is a lot of lint on the yarn ends and yarn tubes, the negative pressure nozzle needs to cover the entire yarn tube, which causes the negative pressure nozzle to carry out lint and dust, which can easily cause the negative pressure nozzle to become clogged. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a swing arm assembly for fancy yarn processing, which has advantages such as reducing the entry of yarn and dust and reducing nozzle clogging. It solves the problem that when sucking up yarn ends, the negative pressure nozzle easily carries out yarn and dust due to the large amount of lint on the yarn ends and yarn tubes, thus easily causing the negative pressure nozzle to become clogged.

[0006] To achieve the above objectives, this application provides the following technical solution: a swing arm assembly for fancy yarn processing, comprising a lifting swing arm cylinder, the output end of which is fixedly connected to a swing arm body, a threaded cylinder fixedly connected to the inner wall of the swing arm body, a threaded tube threadedly connected to the inner wall of the threaded cylinder, a suction nozzle fixedly installed at the bottom end of the threaded tube, a filter screen one fixedly installed on the inner wall of the suction nozzle, a threading tube fixedly connected to the top end of the filter screen one, a filter screen two fixedly installed on the outer surface of the threading tube, a filter screen three fixedly installed on the outer surface of the threading tube, a flexible tube fixedly connected to the top end of the threaded cylinder, a pipe fixedly connected to the other end of the flexible tube, and a negative pressure pump fixedly installed at the bottom end of the pipe.

[0007] The above solution aims to reduce the entry of lint and dust from the spool into the suction nozzle during thread extraction, thus minimizing nozzle clogging. A filter screen (Filter 1) is installed on the inner wall of the nozzle, with a threading tube mounted on top of it. Filter screens (Filter 2 and Filter 3) are installed on the outer surface of the threading tube. The different perforations on the surfaces of filters 1, 2, and 3 allow for the filtration of various substances. Furthermore, all three filters are conical, enabling the thread to pass through the conical surface into the upper threading tube. This reduces the entry of lint and dust without hindering thread extraction, thereby reducing nozzle clogging. The threaded spool and tube facilitate nozzle disassembly and cleaning of the internal filter screens. A negative pressure pump, pipes, and hoses enable negative pressure extraction of the thread from the nozzle.

[0008] Furthermore, a fixing block is fixedly connected to the outer surface of the negative pressure pump, and a base plate is fixedly connected to the left side of the fixing block. The bottom end of the lifting swing arm cylinder is fixedly connected to the upper surface of the base plate.

[0009] The above solution involves installing a fixing block on the outer surface of the negative pressure pump to form a fixed connection, and installing the base plate on the fixing block to fix the negative pressure pump. The bottom end of the lifting arm cylinder is fixed to the base plate so that the lifting arm cylinder can be limited. Through the lifting arm cylinder and the arm body, the movement and angle adjustment of the suction nozzle can be achieved.

[0010] Furthermore, a motor is fixedly connected to the inner top wall of the base plate, and a gear is fixedly connected to the output shaft of the motor.

[0011] The above method involves mounting the motor on the inner top wall of the base plate as a fixed connection, and installing gear one on the output shaft of the motor so that gear one can rotate through the motor.

[0012] Furthermore, a second gear meshes with the outer surface of the first gear, and a fixing rod is fixedly connected to the inner wall of the second gear.

[0013] With the above scheme, a second gear is set on the side of the first gear. The connection between the second gear and the first gear allows the second gear to rotate. A fixing rod is installed on the inner wall of the second gear and fixed in place. The rotation of the second gear allows the fixing rod to rotate.

[0014] Furthermore, the outer surface of the fixing rod is rotatably connected to the inner wall of the base plate, and a limit member is fixedly connected to the outer surface of the fixing rod.

[0015] The above solution connects the outer surface of the fixing rod to the inner wall of the base plate in a rotatable manner, so that the fixing rod can be limited to the center position of the base plate. The limiting component is installed on the outer surface of the fixing rod, and the limiting component enables the fixing rod to rotate stably on the base plate.

[0016] Furthermore, a storage tray is fixedly connected to the outer surface of the fixing rod, and a limiting rod arranged at equal intervals is fixedly connected to the upper surface of the storage tray.

[0017] The above method involves installing the storage tray on the outer surface of the fixed rod, forming a fixed connection. The rotation of the fixed rod allows the storage tray to rotate, and the limiting rod is installed on the upper surface of the storage tray, achieving the positioning and installation effect of the limiting rod.

[0018] Furthermore, a yarn magazine is fixedly connected to the outer surface of the fixing rod, and the outer surface of the yarn magazine is provided with placement slots arranged at equal intervals.

[0019] The above method involves mounting the yarn storage compartment on the surface of a fixed rod. The rotation of the fixed rod allows the yarn storage compartment to rotate, and equidistant placement slots are created on the outer surface of the yarn storage compartment to achieve positioning of the placement slots.

[0020] Furthermore, each of the placement slots is provided with a yarn tube inside, and the inner wall of each yarn tube is fitted with the outer surface of the corresponding limiting rod.

[0021] The above method involves placing the yarn tube inside the corresponding placement slot and connecting the yarn tube to the corresponding limiting rod, so that the yarn tube can be limited within the placement slot.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects: This swing arm assembly for fancy yarn processing includes components such as filter screen one, threading tube, filter screen two, and filter screen three. Filter screen one is installed on the inner wall of the suction nozzle, and the threading tube is connected to filter screen one. Filter screen two and filter screen three are fixed on the outer surface of the threading tube. The conical surface of filter screen one guides the yarn end into the threading tube. Filter screen one, filter screen two, and filter screen three reduce the entry of lint and dust, thereby reducing nozzle clogging. The connection between the threaded cylinder and the threaded tube allows the suction nozzle to be installed and removed for easy cleaning of the suction nozzle and filter screens. A motor and gear one enable gear two to drive the fixed rod to rotate, which in turn causes the yarn magazine to move the corresponding yarn tube to change position, improving the efficiency of the suction nozzle in picking up the yarn end.

[0029] Please see Figure 3 Gear 16 has a gear 17 meshing on its outer surface. A fixing rod 18 is fixedly connected to the inner wall of gear 17. Gear 17 is set on the side of gear 16. The connection between gear 17 and gear 16 allows gear 17 to rotate. The fixing rod 18 is installed on the inner wall of gear 17 and fixed. The rotation of gear 17 allows the fixing rod 18 to rotate.

[0030] Please see Figure 3The outer surface of the fixing rod 18 is rotatably connected to the inner wall of the base plate 14. A limiting member 24 is fixedly connected to the outer surface of the fixing rod 18. The outer surface of the fixing rod 18 is connected to the inner wall of the base plate 14 in a rotatable manner, so that the fixing rod 18 can be limited to the center position of the base plate 14. The limiting member 24 is installed on the outer surface of the fixing rod 18, and the fixing rod 18 can rotate stably on the base plate 14 through the limiting member 24.

[0031] Please see Figure 1 and Figure 3 A storage tray 19 is fixedly connected to the outer surface of the fixing rod 18, and a limiting rod 20 arranged at equal intervals is fixedly connected to the upper surface of the storage tray 19. The storage tray 19 is installed on the outer surface of the fixing rod 18 and set as a fixed connection.

[0034] This embodiment of a swing arm assembly for fancy yarn processing includes components such as filter screen 6, threading tube 7, filter screen 8, and filter screen 9. Filter screen 6 is installed on the inner wall of the suction nozzle 5, and the threading tube 7 is connected to filter screen 6. Filter screens 8 and 9 are fixed on the outer surface of the threading tube 7. The conical surface of filter screen 6 guides the yarn end into the threading tube 7. Filter screens 6, 8, and 9 reduce the entry of lint and dust, thereby reducing clogging of the suction nozzle 5. The connection between the threaded cylinder 3 and the threaded tube 4 allows the suction nozzle 5 to be installed and removed for easy cleaning of the suction nozzle 5 and the filter screen. The motor 15 and gear 16 cause gear 2 17 to drive the fixed rod 18 to rotate, which in turn causes the yarn magazine 21 to move the corresponding yarn tube 23 to change position, improving the efficiency of the suction nozzle 5 in picking up the yarn end.

[0035] It should be noted that when gear 16 rotates, it drives gear 2 17 to rotate, causing the fixed rod 18 to rotate. Through the fixed rod 18, the yarn magazine 21 drives the corresponding yarn tube 23 to rotate, and the yarn tube 23 can stay below the suction nozzle 5. The lifting swing arm cylinder 1 can drive the swing arm body 2 to rise and rotate, thereby enabling the suction nozzle 5 to rise and swing.

[0036] The working principle of the above embodiments is as follows: When picking up the thread end, the yarn tube 23 is placed on the surface of the corresponding limiting rod 20. The motor 15 and gear 16 cause gear 17 to rotate, which in turn causes the fixing rod 18 to drive the yarn magazine 21 to rotate, so that the corresponding yarn tube 23 can stop below the suction nozzle 5. Then, the lifting swing arm cylinder 1, through the swing arm body 2, allows the suction nozzle 5 to be fitted onto the yarn tube 23. Negative pressure is generated by the negative pressure pump 12, pipe 11 and hose 10, and then the thread end is picked up through the suction nozzle 5. During the picking process, the thread end is picked up by the filter screen 6 set inside the suction nozzle 5. The head can be guided into the thread tube 7, and some lint and dust during the suction process can be filtered by filter screen 6, filter screen 8 and filter screen 9, so that the device can effectively reduce the entry of lint and dust, thereby reducing the clogging of the suction nozzle 5. Then, the lifting swing arm cylinder 1 drives the suction nozzle 5 to reset. At this time, the thread end is pulled, and then the rotation of gear 17 causes the yarn magazine 21 to enter the next process. By setting the threaded cylinder 3 and the threaded tube 4, the suction nozzle 5 can be easily disassembled, thereby making the suction nozzle 5 and the internal filter screen easy to clean.
