In particular, a highly efficient fabric winding device can improve the smoothness of the overall production process, reduce manual intervention, lower production costs, and drive the entire textile industry towards a more modern and efficient direction.

[0003] To achieve the winding and unloading of fabric from the circular knitting machine, the current method involves using simple mechanical equipment to assist in winding the fabric. After the fabric is wound to a certain extent, workers need to manually remove the wound fabric from the winding component. Although this method is simple to operate, it is inefficient and the long-term repetitive labor can easily lead to worker fatigue and affect the quality of work. Utility Model Content

[0004] In order to improve work efficiency and alleviate the situation where long hours of repetitive labor lead to worker fatigue and thus affect work quality, this application provides a fabric winding device for a large circular knitting machine.

The rotation axis of the drive inner rod is perpendicular to the fabric output direction. The winding core is detachably sleeved on the drive inner rod and is used for winding the fabric.

[0008] By adopting the above technical solution, different batches of fabric need to be matched with winding cores of different sizes. The detachable winding cores make the winding structure suitable for winding different batches of fabric.

[0014] By adopting the above technical solution and using a threaded connection, the installation and disassembly of the winding core are convenient. After the fabric has finished winding on the winding core, the two connecting sleeves can be turned to disengage the two ends of the winding core from the first drive rod and the second drive rod respectively, and the winding core can be easily removed from the drive inner rod.

[0031] This application discloses a fabric winding device for a large circular knitting machine, which is used to improve work efficiency and alleviate the situation where long-term repetitive labor causes worker fatigue and thus affects work quality.

[0032] refer to Figure 1 , Figure 2 and Figure 3 A fabric winding device for a circular knitting machine includes a frame 110, on which a winding structure 120, a transport component 130, and a discharge receiving component 140 are arranged. The winding structure 120 is used for winding fabric. The discharge receiving component 140 is arranged on the transport component 130. The transport component 130 is used to drive the discharge receiving component 140 to the bottom of the winding structure 120 to receive the wound fabric. The transport component 130 is provided with a flipping component 150 that drives the discharge receiving component 140 to flip and unload the fabric. The cooperation between the transport component 130 and the flipping component 150 makes the unloading process continuous and fast, making the fabric winding and unloading process of the circular knitting machine more automated, improving production efficiency, reducing manual intervention, and improving the situation where long-term repetitive labor causes worker fatigue and thus affects work quality.

[0033] Specifically, refer to Figure 3 and Figure 4 The winding structure 120 includes a drive inner rod 121 and a winding core 122. The drive inner rod 121 is rotatably connected to the frame 110, and the rotation axis of the drive inner rod 121 is perpendicular to the fabric output direction. The drive inner rod 121 includes a first drive rod 1211 and a second drive rod 1212. The opposite ends of the first drive rod 1211 and the second drive rod 1212 are inserted together. The back ends of the first drive rod 1211 and the second drive rod 1212 are rotatably connected to the frame 110. In this embodiment, the frame 110 includes a base 111 and two mounting rods 112. The two mounting rods 112 are symmetrically arranged on the base 111, and one of the mounting rods 112 is mounted on the drive inner rod. The output shaft of the drive motor 113 is coaxially connected to the first drive rod 1211. The second drive rod 1212 is rotatably connected to another mounting rod 112. A positioning post 123 is coaxially provided on the end face of the first drive rod 1211 near the second drive rod 1212. A slot 124 for the positioning post 123 to be inserted is provided on the end face of the second drive rod 1212 near the first drive rod 1211. The depth direction of the slot 124 is opened along the axial direction of the second drive rod 1212. A positioning element 125 is provided on the positioning post 123. A positioning groove 126 for the positioning element 125 to be embedded is provided on the second drive rod 1212. The positioning groove 126 is opened on the groove wall of the slot 124.

[0034] The positioning element 125 includes a positioning block 1251 and a connecting spring 1252. A positioning groove 127 is provided on the positioning post 123. The depth direction of the positioning groove 127 is radially opened along the positioning post 123. One end of the connecting spring 1252 is connected to the bottom of the positioning groove 127, and the other end of the connecting spring 1252 is connected to the positioning block 1251. The positioning block 1251 is used to be embedded in the positioning groove 126. In this embodiment, a total of three sets of positioning elements 125 are provided on the positioning post 123. The three sets of positioning elements 125 are equally spaced along the circumference of the positioning post 123.

[0035] Further, refer to Figure 2A drive member 160 is provided on the frame 110. The drive member 160 is used to drive the first drive rod 1211 and the second drive rod 1212 to move closer or further apart along the length direction of the rotation axis of the inner drive rod 121. In this embodiment, the drive member 160 includes a drive screw 161 and a screw motor 162. The drive member 160 is disposed on the base 111. A sliding guide groove 114 is formed on the upper surface of the base 111. The depth direction of the sliding guide groove 114 is perpendicular to the upper surface of the base 111. The length direction of the sliding guide groove 114 is parallel to the axial direction of the drive inner rod 121. Two sliding guide grooves 114 are symmetrically opened. The two sliding guide grooves 114 and the two mounting bracket rods 112 correspond one-to-one. The bottom of the mounting bracket rod 112 is embedded in the sliding guide groove 114. The drive screw 161 is embedded in the sliding guide groove 114. One end of the drive screw 161 is axially fixed to the groove wall of the sliding guide groove 114 and rotates circumferentially. The other end passes through the bottom of the mounting bracket rod 112 and is coaxially connected to the output shaft of the screw motor 162.

[0036] refer to Figure 2 and Figure 4 When the lead screw motor 162 operates, driving the drive lead screw 161 to rotate, it causes the two mounting bracket rods 112 and the first drive rod 1211 and the second drive rod 1212 on the mounting bracket rod 112 to move closer to each other. At this time, the positioning pin 123 is inserted into the slot 124, and the positioning block 1251 is embedded into the positioning groove 126 under the action of the connecting spring 1252, thus achieving positioning. When disassembly is required, the first drive rod 1211 and the second drive rod 1212 move away from each other, which can overcome the elastic force of the connecting spring 1252 and cause the positioning block 1251 to disengage from the positioning groove 126, thereby separating the first drive rod 1211 and the second drive rod 1212. This method makes the connection of the first drive rod 1211 and the second drive rod 1212 more stable and ensures the stability when the inner drive rod 121 rotates.

[0037] In addition, refer to Figure 3 and Figure 5 The winding core 122 is detachably sleeved on the drive inner rod 121. The winding core 122 is used for winding the fabric. Different batches of fabric require different sizes of winding core 122. The detachable winding core 122 allows the winding structure 120 to be suitable for winding different batches of fabric.

[0038] Specifically, both the first drive rod 1211 and the second drive rod 1212 are provided with connectors. The connectors are used to fix the two ends of the winding core 122 to the first drive rod 1211 and the second drive rod 1212 respectively. The first drive rod 1211 and the second drive rod 1212 are inserted into each other, and the winding core 122 is detachably engaged with the connectors. This allows the winding structure 120 to effectively drive the winding core 122 to rotate and realize the fabric winding, and also facilitates the disassembly and installation of the winding core 122. In this embodiment, the connector is a connecting sleeve 170. The inner wall of the connecting sleeve 170 is provided with a first internal thread 171 and a second internal thread 172. The first internal thread 171 and the second internal thread 172 are connected along the connecting sleeve 170. The sleeves 170 are arranged in a stepped manner along the axis. The first drive rod 1211 and the second drive rod 1212 are both provided with a first external thread 173 that matches the first internal thread 171 on their respective end rod walls. The winding core 122 is provided with a second external thread 174 that matches the second internal thread 172 on its two end side walls. The threaded connection facilitates the installation and removal of the winding core 122. After the fabric is wound on the winding core 122, the two connecting sleeves 170 can be turned to disengage the connection between the two ends of the winding core 122 and the first drive rod 1211 and the second drive rod 1212, respectively, and the winding core 122 can be easily removed from the drive inner rod 121.

[0039] In addition, refer to Figure 1 and Figure 2 The unloading receiving component 140 includes a receiving box 141 and a guide plate 142. In this embodiment, the transport component 130 includes a transport trolley 131 and two support frames 132 vertically arranged on the transport trolley 131. The tilting component 150 is a tilting motor, which is arranged on one of the support frames 132. The receiving box 141 is arranged between the two support frames 132. A transmission rod is coaxially connected to the output shaft of the tilting motor. The end of the transmission rod away from the tilting motor is connected to the outer wall of the receiving box 141. The side wall of the receiving box 141 away from the transmission rod is rotatably connected to the other support frame 132 through a connecting rod.

[0040] Specifically, the receiving box 141 has an open top for receiving the fabric roll falling from the winding structure 120. The receiving box 141 is generally made of welded steel plate, which has good strength and rigidity and can withstand the weight of the fabric roll. The guide plate 142 extends obliquely from one side of the receiving box 141. The function of the guide plate 142 is to guide the fabric roll to slide smoothly out of the receiving box 141 during unloading. A smooth plastic film can also be laid on the surface of the guide plate 142 to reduce friction. After the fabric roll is received in the receiving box 141, the flipping component 150 is activated, pushing the receiving box 141 to flip towards the guide plate 142. The fabric roll slides out along the guide plate 142, completing the unloading process.

[0041] The implementation principle of the fabric winding device of a large circular knitting machine according to an embodiment of this application is as follows: Through reasonable structural design, the fabric winding and unloading are automated. The design of the drive inner rod 121 in the winding structure 120 facilitates the installation and disassembly of the winding core 122 and can stably drive the winding core 122 to rotate for fabric winding. The cooperation between the transport component 130 and the unloading receiving component 140 makes the receiving and unloading process of the fabric roll continuous and efficient. The setting of the flipping component 150 further improves the automation level of unloading, avoids manual intervention, and makes the fabric winding and unloading process of the large circular knitting machine more automated, improves production efficiency, reduces manual intervention, and improves the situation where long-term repetitive labor leads to worker fatigue and thus affects work quality.

[0042] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
