Description

Technical Field

[0001] This utility model relates to production equipment for patchwork carpets, and in particular to an automatic yarn bobbin conveying device for a yarn winding machine. Background Technology

[0002] The structure of a patchwork carpet consists of a tufted blanket on top and a backing material such as a mesh fabric or non-woven fabric underneath. The tufted blanket is made of yarn spun from synthetic fibers such as nylon, polypropylene, or polyester, which is tufted onto a non-woven fabric using a tufting machine to create a tufted blank carpet. Before tufting the carpet with these synthetic fiber yarns, standard bobbins need to be wound to a fixed length onto empty bobbins using a winding machine according to process requirements. The bobbins with the yarn wound are then fed to the tufting machine for tufting. This equipment for winding large bobbins onto the bobbins is called a winding machine. When the yarn on the bobbins reaches the set length, the winding machine automatically cuts the yarn, and the bobbins are unloaded into a storage trough by a bobbin-turning device. The bobbins are then manually removed from the storage trough and framed. In actual operation, it was found that the bobbin storage trough of the original winding machine was too small. If the bobbins in the storage trough were not removed in time, the bobbins would accumulate in the storage trough. When the bobbin rewinding device flips over to unload the rewinded bobbins, the rewinding device would hit the bobbins that had not yet been removed, which could easily damage the rewinding device. Utility Model Content

[0003] The purpose of this invention is to provide an automatic yarn bobbin conveying device for a winding machine that eliminates the need for manual picking of bobbins from the storage trough into a basket, prevents the bobbin rewinding device from colliding with the bobbins in the storage trough, and is simple in structure and easy to modify.

[0004] To achieve the above requirements, this utility model is implemented through the following technical solution. Its shape and installation position are similar to the bobbin storage trough of the original winding machine. Its cross-section is L-shaped, including a bottom surface and a guardrail that is basically perpendicular to the bottom surface. Its feature is that a belt conveyor device is provided on the bottom surface. The belt conveyor device includes pulleys installed on both ends of the belt conveyor device cover on the frame, and a conveyor belt sleeved on the two pulleys. The pulley is an external rotor motor. The conveyor belt is sleeved on the external rotor, with the stator in the center and fixed to the belt conveyor device cover. When the external rotor motor rotates, the conveyor belt will move in a cycle, moving the bobbins that fall off the conveyor belt to one end of the belt conveyor device, where they fall into a basket that is collected at that end.

[0005] The linear speed of the conveyor belt is 6-10 meters per minute.

[0006] Multiple conveyor belt tensioning devices are provided below the conveyor belt.

[0007] The conveyor belt tensioning device includes a tensioning wheel located close to the bottom of the conveyor belt. Positioning shafts are installed at both ends of the tensioning wheel. Rolling bearings or sliding bearings are installed between the tensioning wheel and the positioning shafts. The positioning shafts are fixed in the arc-shaped adjustment groove of the belt conveyor cover. An 8-shaped tie rod is fitted on the positioning shaft. The other end of the 8-shaped tie rod is fixed to a positioning seat. The positioning seat is fixed in a positioning hole on the belt conveyor cover. The center distance of the 8-shaped tie rods is equal to the center distance between the positioning hole and the arc-shaped adjustment groove.

[0008] This utility model is an improvement on the bobbin storage trough in the original winding machine. Based on the above design, an automatic bobbin conveying device for a winding machine is designed. Because a belt conveyor is installed at the bottom of the bobbin storage trough, when bobbins from the winding machine fall into the trough and are conveyed by the belt conveyor, they are promptly moved to the outlet end of the trough. Below the outlet end is a basket for receiving bobbins, which naturally falls into the basket. Workers only need to collect the bobbins that have fallen into the basket at the outlet end, eliminating the need to walk around the entire trough to pick up bobbins and put them into the basket. Furthermore, it prevents bobbins from piling up in the trough, thus avoiding damage to the bobbin-receiving device caused by the rewinding device touching unremoved bobbins. The pulley design utilizes an existing external rotor motor, with the motor housing also serving as the pulley, reducing the number of parts in the transmission and speed-changing mechanisms and greatly simplifying the structure of the conveying device.

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0014] Figure 1 , Figure 2 , Figure 3This is a schematic diagram of an automatic yarn bobbin conveying device for a winding machine. As shown in the diagram, its shape and installation position are similar to the bobbin storage trough of the original winding machine, and its cross-section is L-shaped. Figure 2 As shown, the device includes a base 1 and a guardrail 2 that is substantially perpendicular to the base 1. A belt conveyor 3 is mounted on the base 1. The belt conveyor 3 includes pulleys 6 mounted on both ends of a belt conveyor cover 5 on a frame 4, and a conveyor belt 7 fitted onto the two pulleys 6. The pulleys 6 are external rotor motors (commonly used motors are internal rotor motors). This type of external rotor motor is an existing product. The conveyor belt 7 is fitted onto the external rotor, with the stator at the center and fixed to the belt conveyor cover 5. When the external rotor motor is energized and rotates, the conveyor belt 7 will move cyclically. The linear speed of the conveyor belt 7 is 6-10 meters per minute. As the conveyor belt 7 moves, the drums that fall onto the conveyor belt 7 are moved to one end of the belt conveyor 3 and fall into a collection basket (not shown) at that end (e.g., ...). Figure 1 (As shown by the middle arrow). Multiple conveyor belt tensioning devices 8 are provided below the conveyor belt 7, such as... Figure 3 As shown. The conveyor belt tensioning device 8 includes a tensioning wheel 9 close to the bottom of the conveyor belt 7. Positioning shafts 10 are installed at both ends of the tensioning wheel 9. A rolling bearing or sliding bearing 11 is installed between the tensioning wheel 9 and the positioning shafts 10. The positioning shafts 10 are fixed in the arc-shaped adjusting groove 12 of the belt conveyor cover 5. When the positioning shafts 10 rotate counterclockwise in the arc-shaped adjusting groove 12, the conveyor belt 7 is tensioned. An 8-shaped pull rod 13 is sleeved on the positioning shaft 10. The other end of the 8-shaped pull rod 13 is fixed on a positioning seat 14. The positioning seat 14 is fixed in a positioning hole 15 on the belt conveyor cover 5 to position the conveyor belt tensioning device 8. The center distance of the 8-shaped pull rods 13 is equal to the center distance between the positioning hole 15 and the arc-shaped adjusting groove 12.
