Description

Technical Field

[0001] The utility model relates to the technical field of braiding mechanical equipment, in particular to a wire receiving and feeding mechanism. Background Art

[0002] In the technical field of the knitting machine industry, the take-up device plays a vital role. It is a highly automated mechanical device that integrates a number of advanced technologies such as computer numerical control, electronic drive and precision mechanical design. The core components of the take-up device include the wire and its take-up and delivery mechanism, also known as the take-up and delivery mechanism. In actual operation, when the take-up action is required, the take-up and delivery mechanism is responsible for accurately delivering the wire to ensure that the wire can accurately pass through each take-up loop. Once the take-up process is completed, the take-up and delivery mechanism will quickly and accurately retract the wire and make it safely withdraw from each take-up loop.

[0003] However, under the existing technical background, there is a potential problem in the process of steel wire collection and delivery. Specifically, the steel wire is not wound in the wire collection and delivery mechanism, but is clamped between the wire feeding wheel and the belt. This design causes the wire feeding wheel and the belt to continuously squeeze and rub the steel wire during the process of steel wire retraction, thereby driving the movement of the steel wire. However, this continuous friction not only easily leads to wear of the wire feeding wheel, belt and steel wire itself, but also may cause slippage due to excessive friction, which is not convenient for ensuring the conveying quality of the steel wire.

[0004] Therefore, it is necessary to improve the existing technology.

[0061] Embodiment 1

[0062] In view of the defects of the above-mentioned prior art, the applicant, based on many years of rich practical experience and professional knowledge in the design and manufacture of such products, and in conjunction with the application of theory, actively conducts research and innovation in the hope of creating a technology that can solve the defects of the prior art. After continuous research and design, and after repeated trial samples and improvements, the present utility model with real practical value was finally created.

[0063] Please refer to Figure 1-5 The embodiment of the utility model provides a wire feeding and receiving mechanism, which has a unique structural design and is intended to achieve efficient, stable and durable wire feeding and receiving operations. The mechanism is mainly composed of the following core components: a bottom plate 1, a wire winding disk 2, a plurality of tensioning wheels 3 and a belt 4.

[0064] First, the wire winding disc 2 is carefully designed and installed on the bottom plate 1, and its main function is to provide a stable winding platform for the steel wire 5. The steel wire 5 can be wound in an orderly manner on this disc, thereby ensuring the neatness and stability of the steel wire 5 during the receiving and sending process.

[0065] In order to further enhance the fixing effect of the steel wire 5 on the wire winding drum 2, the wire winding drum 2 is particularly equipped with a fixing mechanism. This mechanism can firmly fix one end of the steel wire 5 to ensure that the steel wire 5 will not produce unnecessary friction and wear due to looseness during the winding and retracting process.

[0066] In addition, several tension wheels 3 are also cleverly installed on the bottom plate 1, and they work together with the wire winding disk 2 to provide strong support for the compression of the steel wire 5; and the belt 4 is cleverly wound between these tension wheels 3 and the wire winding disk 2 to form a tight closed loop system. This design not only ensures the stability of the steel wire 5 during the winding process, but also can fix the steel wire 5 more tightly through the pressure of the belt 4 when the steel wire 5 is retracted to prevent it from being damaged by friction.

[0067] It is worth emphasizing that the wire feeding and receiving mechanism provided in this embodiment effectively solves the problem of easy wear and slippage of the steel wire 5 in the traditional wire feeding and receiving mechanism through a unique fixing mechanism and a compression design of the wire winding disc 2 and the belt 4. When the steel wire 5 is retracted, it is subjected to tension because it is fixed to one end of the wire winding disc 2. This tension will naturally retract it following the rotation of the wire winding disc 2 without the need for additional external force. This design not only reduces the friction between the various parts and prolongs the service life of the mechanism, but also ensures the stability and quality of the steel wire 5 delivery, further improving the durability and reliability of the bottoming device.

[0068] Please refer again Figure 1-3 In this embodiment, the wire feeding and receiving mechanism further refines the design of its fixing mechanism. Specifically, the fixing mechanism includes a carefully designed wire routing channel 6, which is directly opened on the wire winding disk 2, and is intended to provide a stable and accurate routing path for the end of the steel wire 5 to be fixed. The wiring channel 6 is also provided with a fixing hole inside. This design enables the fixing member 7 to pass through the fixing hole, thereby firmly fixing the steel wire 5 in the wiring channel 6.

[0069] Through this structure, one end of the steel wire 5 is accurately fixed in the wire routing channel 6 of the wire winding drum 2, thereby ensuring the stability and reliability of the steel wire 5 during the winding and retracting process.

[0070] In this embodiment, for further optimization of the wire feeding and receiving mechanism, special attention is paid to the contact and transmission mode between the wire winding disc 2 and the belt 4. Specifically, first teeth are provided on the outer side wall where the wire winding disc 2 contacts the belt 4, and second teeth meshing with the first teeth are also provided on the belt 4 accordingly.

[0071] The main purpose of this design is to enhance the transmission efficiency and stability between the winding disk 2 and the belt 4. When the winding disk 2 rotates, the first teeth on it will mesh with the second teeth on the belt 4, thereby driving the synchronous movement of the belt 4. Compared with the traditional direct friction transmission, this method of tooth meshing can further and more effectively reduce sliding and friction losses and improve the accuracy of transmission.

[0072] In addition, due to the meshing action between the teeth, this design can also withstand greater loads and torques, further enhancing the durability and reliability of the wire feeding mechanism. At the same time, by precisely controlling the size and shape of the teeth, more sophisticated transmission control can be achieved, thus better meeting the requirements for accuracy and stability during wire feeding.

[0073] Please refer again Figure 1 and 3 In this embodiment, a more sophisticated design is made for the wire feeding and receiving mechanism. Specifically, the outer wall of the wire winding disk 2 is not only provided with a first tooth meshing with the belt 4, but also an additional wire winding groove 8 is provided. The main purpose of this design is to provide a special winding space for the steel wire 5 to ensure the neatness and stability of the steel wire during the winding process.

[0074] The opening of the wire winding groove 8 enables the steel wire 5 to be accurately wound on the outer side wall of the wire winding drum 2, thereby avoiding confusion and misalignment of the steel wire during the winding process. At the same time, the shape and width design of the wire winding groove 8 can be customized according to the specifications and quantity of the steel wire 5 to meet the needs of different application scenarios.

[0075] When the wire winding disc 2 rotates to retract the steel wire, the steel wire 5 will be retracted in an orderly manner following the rotation of the wire winding disc under the guidance of the wire winding groove 8. This design not only improves the efficiency and stability of steel wire transportation, but also reduces the wear and damage of the steel wire during winding and retracting.

[0076] Please refer again Figure 2 and 4 In this embodiment, in order to enhance the automation and operation efficiency of the wire feeding and receiving mechanism, a driving mechanism is particularly introduced. The driving mechanism is mainly composed of a driving motor 9, a main transmission gear 10 and a slave transmission gear 11, which work together to provide power for the rotation of the wire winding disc 2.

[0077] Specifically, the slave transmission gear 11 is coaxially arranged with the wire winding disk 2, which means that when the slave transmission gear 11 rotates, the wire winding disk 2 will also rotate synchronously. The drive motor 9 is firmly mounted on the base plate 1, and its output end is directly connected to the main transmission gear 10, providing a power source for the entire drive system. The main transmission gear 10 and the slave transmission gear 11 are meshed to achieve power transmission, ensuring that the slave transmission gear 11 can rotate accurately and stably.

[0078] When the driving motor 9 is started, it drives the main transmission gear 10 to rotate. Due to the meshing relationship between the main transmission gear 10 and the slave transmission gear 11, the slave transmission gear 11 will also rotate, thereby driving the rotation of the wire winding disc 2. This design not only improves the automation level of the wire feeding and receiving mechanism, reduces the complexity of manual operation, but also makes the winding and retrieving process of the wire more stable and efficient.

[0079] In addition, since the output torque and rotation speed of the driving motor 9 can be precisely adjusted by the control system, the rotation speed and force of the wire winding disk 2 can be adjusted according to actual needs to meet the winding requirements of steel wires of different specifications and quantities. This flexibility makes the wire feeding and receiving mechanism of this embodiment have a wider application prospect in the knitting machine industry.

[0080] Please refer again Figure 2 and 4 In this embodiment, the layout of the driving mechanism is arranged more reasonably. Specifically, the driving motor 9 is installed on the side of the bottom plate 1 facing away from the main working area. Such a layout not only makes the structure of the entire wire feeding and receiving mechanism more compact, but also avoids unnecessary interference of the driving motor 9 on the winding and retracting process of the steel wire 5.

[0081] In order to realize the power transmission between the driving motor 9 and the main transmission gear 10, a through hole 12 is specially provided on the bottom plate 1. The design of the through hole 12 allows the output end of the driving motor 9 to directly pass through the bottom plate 1 and connect with the main transmission gear 10 located on the other side of the bottom plate 1.

[0082] In addition, this layout and design also facilitates maintenance and replacement of the drive motor 9. When the motor needs to be repaired or replaced, it can be simply operated from the back of the bottom plate 1 without disassembling the entire wire feeding and receiving mechanism. This convenience further improves the practicality and reliability of the wire feeding and receiving mechanism.

[0083] In this embodiment, in order to further improve the accuracy and stability of steel wire transportation, a wire feeding guide mechanism is specially introduced. The main function of this mechanism is to accurately guide the transported steel wire 5 to ensure that it moves according to the predetermined path and direction.

[0084] The specific design of the wire guide mechanism can be adjusted and optimized according to actual needs. For example, it can include a series of guide wheels, guide grooves or other guide elements that are carefully arranged on the wire conveying path to guide the wire along a specific trajectory. Through the synergistic effect of these guide elements, the wire guide mechanism can ensure that the wire always remains stable during the conveying process, avoiding problems such as deviation or jitter.

[0085] Please refer again Figure 2 In this embodiment, the wire feeding guide mechanism is further refined and improved. Specifically, the wire feeding guide mechanism includes two wire feeding guide seats 13, and the two wire feeding guide seats 13 each undertake different guiding tasks.

[0086] A guide hole is provided inside one of the wire feeding guide seats 13, and the function of the guide hole is to provide a precise passage for the steel wire 5, so as to ensure that the steel wire 5 does not deviate from the predetermined path during the transmission process. The steel wire 5 can freely pass through the guide hole while maintaining its stability and straightness.

[0087] The other wire feeding guide seat 13 is penetrated by a guide tube 14. The guide tube 14 provides a more clear and long-distance fixed path, and the steel wire 5 is penetrated inside the guide tube 14 for transmission. This design further enhances the stability and accuracy of the transmission of the steel wire 5 and reduces the deviation and jitter of the steel wire 5 during the transmission process.

[0088] Through the cooperation of the two wire feeding guide seats 13, the wire feeding guide mechanism can effectively guide the steel wire 5, ensuring that it can remain stable and accurate throughout the entire transmission process, which not only improves the efficiency of steel wire transmission, but also improves the performance of the entire wire feeding and receiving mechanism.

[0089] In addition, this design also makes the wire feeding guide mechanism easier to install and maintain. The setting of the guide hole and the guide tube 14 is relatively simple and can be adjusted or replaced according to actual needs. This provides great convenience for the daily maintenance and care of the equipment.

[0090] Please refer again Figure 2 In this embodiment, the wire feeding guide mechanism is further optimized and improved. Specifically, a guide ring 15 is added to the wire feeding guide mechanism, and this design is intended to solve the problem that the steel wire 5 may be blocked during the feeding process.

[0091] The guide ring 15 is arranged on the transmission path of the steel wire 5, and the steel wire 5 is inserted into the guide ring 15. Compared with the previous guide hole and guide tube 14, the guide ring 15 has a larger diameter. This design allows the steel wire 5 to have a certain amount of activity space in the guide ring 15. When the steel wire is obstructed or encounters an abnormal situation during the transmission process, it can be elastically deformed inside the guide ring 15, thereby avoiding damage to the steel wire or other equipment.

[0092] When the steel wire 5 is obstructed and elastically deformed at the guide ring 15, the system will receive a fault signal because the steel wire 5 changes from being out of contact with the guide ring 15 to being in contact with the guide ring 15. This signal will trigger a protection mechanism, causing the drive motor 9 to stop working immediately, thereby preventing the motor from continuing to run. After the motor stops, the operator can manually intervene to check and eliminate the fault.

[0093] The introduction of the guide ring 15 not only enhances the flexibility and reliability of the wire feeding guide mechanism, but also improves the safety and usability of the entire wire feeding and receiving mechanism. Through this design, the steel wire and equipment can be better protected, the occurrence of failures can be reduced, and production efficiency can be improved.

[0094] Please refer again Figure 2 and 5 In this embodiment, the wire feeding guide mechanism is further improved, and a stop sensing mechanism is added. The main function of this mechanism is to sense the wire feeding status of the steel wire 5 in real time, and output a stop signal when necessary, such as when the steel wire 5 is fed out, to ensure the safety and stability of the steel wire during the feeding process.

[0095] The shutdown sensing mechanism includes a slider 16 and a sensor 17;

[0096] The sensor 17 is disposed on the bottom plate 1;

[0097] A spiral groove 18 is formed on one side of the transmission gear 11 toward the slider 16, and a latch 19 is inserted into the spiral groove 18, and the latch 19 is connected to the slider 16;

[0098] The slider 16 is slidably disposed on the bottom plate 1 , and can move closer to or farther from the sensor 17 under the drive of the latch 19 .

[0099] When the transmission gear 11 rotates with the wire winding disc 2, the latch 19 will move along the spiral groove 18 in the spiral groove 18. Since the latch 19 is connected to the slider 16, the slider 16 will also slide accordingly on the bottom plate 1 under the drive of the latch 19.

[0100] Under normal circumstances, the slider 16 is not close enough to the sensor 17 and is no longer within the sensing range of the sensor 17, and the sensor 17 will not output a stop signal. However, for example, when the steel wire 5 is fed out, the slider 16 is closest to the sensor 17 and is within the sensing range of the sensor 17, and the sensor 17 will immediately output a stop signal to cut off the power supply or take other emergency measures to protect the mechanism from damage.

[0101] The design of this shutdown sensing mechanism is simple and effective. It can sense the wire feeding status of the wire in real time and perform emergency shutdown when necessary, ensuring the safety and stability of the equipment.

[0102] Please refer to Figure 6 , in this embodiment, the wire feeding and receiving mechanism further includes an elastic tensioning device;

[0103] The elastic tensioning device is used to adjust the tension of the belt 4 , and is composed of a plurality of key components, which work together to achieve fine adjustment of the tension of the belt 4 .

[0104] Specifically, the elastic tensioning device includes a fixing seat 20, a fixing screw 21, a compression spring 22 and a connecting rod 23;

[0105] The fixing base 20 is fixedly connected to the base plate 1; the fixing base 20 is the basis of the entire elastic tensioning device, and it is tightly combined with the base plate 1 through a stable connection method, providing stable support for the entire device.

[0106] The fixing screw 21 is passed through the fixing seat 20 ; as a key connection and adjustment component, the fixing screw 21 is cleverly passed through the fixing seat 20 , which not only plays a connecting role, but also affects the tensioning effect by adjusting its position.

[0107] The compression spring 22 is sleeved on the fixing screw 21; the compression spring 22 is an elastic element in the device, which is carefully sleeved on the fixing screw 21. The elastic characteristics of the spring enable it to produce corresponding deformation according to the change of external force, thereby realizing the tension adjustment of the tension wheel 3.

[0108] One end of the connecting rod 23 is connected to the tension wheel 3, and the other end is arranged between the compression spring 22 and the fixing seat 20. The connecting rod 23 is a key component connecting the tension wheel 3 and the elastic element, one end of which is tightly connected to the tension wheel 3, and the other end is cleverly arranged between the compression spring 22 and the fixing seat 20. This design enables the connecting rod 23 to move with the deformation of the compression spring 22, thereby driving the tension wheel 3 to make corresponding adjustments, and finally realizing accurate control of the tension of the belt 4.

[0109] It should be noted that, during the operation of the wire feeding and receiving mechanism, the belt 4 will be affected by the frequency of use and become hot and weak, which will correspondingly cause the circumference to slightly increase. At this time, the belt 4 will not be able to effectively wrap the steel wire 5, and the steel wire 5 will not be arranged in order in the wire winding groove 8 of the wire winding disk 2. After adding the elastic tensioning device, the steel wire 5 can be effectively wrapped and pre-tightened in real time, reducing the use accuracy error of the belt 4 and the dimensional error during the processing.

[0110] Although the terms such as base plate, wire winding disk, tension wheel, belt, steel wire, etc. are used more frequently in this application, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.

[0111] The utility model provides a wire receiving and feeding mechanism, which provides a fixing mechanism for fixing one end of the steel wire on the wire winding reel, so that the steel wire can be wound on the wire winding reel, and cooperates with the belts wound on each tensioning wheel and the wire winding reel to compact the steel wire. Since the steel wire with one end fixed on the wire winding reel is subjected to tension when being retracted, it follows the rotation of the wire winding reel and is retracted into the wire winding reel. Therefore, it is no longer prone to wear of various parts due to friction, and no slipping due to excessive friction will occur. This is beneficial to ensuring the conveying quality of the steel wire and improving the durability and stability of the bottoming device.
