Description

Technical Field

[0001] The present invention relates to the technical field of wire winding, and particularly to an automatic wire winder for metal wires based on self-replacement processing. Background Art

[0002] Due to the material properties of metal wires, the winding process of metal wires is mainly mechanical. For relevant content, reference can be made to the publications with publication numbers CN102172667A and CN115570008A. In essence, it is to mechanically pull the metal wire and continuously wind it on structures such as a take-up reel.

[0003] After winding to a certain length, the take-up reel needs to be replaced, and equipment such as an AGV cart can be used for operation. During the replacement process, it is necessary to perform fixed-point cutting according to the winding process. It should be noted that: During the continuous traction process of metal wires, large metal stresses (tensile forces) will be generated. When the wire is cut, the metal stress is instantaneously released and the wire will move in an undetermined direction. On the one hand, there is a safety hazard of injuring the staff. On the other hand, it is difficult to re-fix the cut metal wire on the take-up reel, and this re-fixing process takes a long time.

[0004] For this, the present application proposes a solution. Summary of the Invention

[0005] The purpose of the present invention is to provide an automatic wire winder for metal wires based on self-replacement processing. Due to the material properties of metal wires, large metal stresses are generated during the continuous traction and winding process. During the process of replacing the winding reel, since the metal stress is instantaneously released when the wire is cut, on the one hand, there is a safety hazard, but the key is that it affects the subsequent winding process.

[0006] The purpose of the present invention can be achieved through the following technical solutions: An automatic wire winder for metal wires based on self-replacement processing includes a frame assembly, a wire body, a drive assembly, an air pump assembly, a first motor, and a second motor. A winding component corresponding to the drive assembly is provided in the frame assembly, and a two-rotation component and an intermediate roller are provided on the frame assembly;

[0007] The two-rotation component includes a fixed rod, a lever, a pressure roller, and a threading roller. The pressure roller is installed at one end of the fixed rod. The threading roller is installed at the other end of the fixed rod and one end of the lever. The end positions of the fixed rod and the lever close to each other are rotatably connected. The output shaft of the first motor penetrates the frame assembly and is fixedly connected to the other end position of the fixed rod;

[0008] One end inside the wire threading roller is provided with an oil cylinder piston, and a wire threading groove is opened at the position of the wire threading roller corresponding to the oil cylinder piston. Outer arc sleeves and directional arc rods are respectively installed on the outer wall positions of the fixed rod and the lever close to each other. The directional arc rod is slidably connected in the outer arc sleeve, and a connecting spring is installed at the position of the directional arc rod corresponding to the inside of the outer arc sleeve.

[0009] It is further set that: the frame assembly includes a fixed frame, two turntables and an inner turntable. The center points of the fixed frame, the two turntables and the inner turntable are collinear. The two turntables are located in the middle of the fixed frame and the inner turntable, and the two turntables are rotatably connected to the fixed frame and the inner turntable.

[0010] It is further set that: the air pump assembly, the first motor and the two-rotation assembly are arranged on the two turntables, the intermediate roller is arranged on the fixed frame, and the two-rotation assembly is located in the middle of the intermediate roller and the wire winding assembly.

[0011] It is further set that: the wire winding assembly includes a transmission assembly rod, a cooperating sleeve and a wire winding plate. The transmission assembly rod is arranged at the output end position corresponding to the drive assembly. The cooperating sleeve is arranged on the outer wall of the transmission assembly rod, and a pressure receiving shifting sleeve corresponding to the wire winding plate is installed outside the cooperating sleeve.

[0012] It is further set that: the wire winding plates are arranged in an annular array along the center point of the cooperating sleeve, and hinge connecting rods are arranged between the wire winding plates and the pressure receiving shifting sleeve. Through grooves corresponding to the wire winding plates are opened on the inner turntable.

[0013] It is further set that: a driving gear is installed at the output end position of the second motor, and the driving gear meshes with the inner wall of the two turntable.

[0014] It is further set that: the fixed rod is arranged close to the wire winding assembly, and the lever is arranged close to the intermediate roller.

[0015] It is further set that: the wire body first passes through the winding of the intermediate roller and then passes through the wire threading grooves through two wire threading rollers and finally winds around the wire winding assembly.

[0016] The present invention has the following beneficial effects:

[0017] 1. Improve the winding process of the wire body. Specifically, the threading roller, pressing roller, and transfer roller in the two-rotation assembly are used to change the winding direction of the wire body. The essence is that the wire body actively "forms" a bending position. The pressing roller does not participate in the winding process of the wire body. The threading roller cooperates with the transfer roller to change the winding direction of the wire body. The key lies in hydraulically pressing the wire body with the threading roller during the cutting action to prevent the wire body from releasing a large tensile force at the moment of cutting and affecting the external working environment. The key purpose is to directly position the wire body after cutting, facilitate the re-threading process in the subsequent winding action, and reduce the working intensity and working time of subsequent re-threading.

[0018] 2. Further explanation in combination with the fixed rod and the lever: The fixed rod is a relatively fixed structure, while the lever swings freely relative to the fixed rod. Thus, the two threading rollers on the lever can directly affect the winding direction of the wire body, or the winding direction of the wire body directly affects the setting direction of the two threading rollers. More specifically, the fixed rod and the lever serve as the bearing structures when the tensile force is released, preventing the direct impact of the tensile force release process on the external working environment.

[0028] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0029] Embodiment 1: Due to the material characteristics of the metal wire, large metal stress is generated during its continuous traction and winding process. And during the process of replacing the winding wheel, since the metal stress is instantaneously released when the wire is cut, on the one hand, there are potential safety hazards, but the key is that it affects the subsequent winding process. Therefore, the following technical solutions are proposed:

[0030] Refer to Figures 1 to 7 , the automatic wire coiling machine based on self - replacement processing in this embodiment includes a frame assembly, a wire body, a driving assembly 11, an air pump assembly 8, a first motor 9 and a second motor 10. A wire winding component corresponding to the driving assembly 11 is arranged in the frame assembly, and a two - rotation component and an intermediate roller 4 are arranged on the frame assembly;

[0031] The two - rotation component includes a fixed rod 5, a pushing rod 6, a pressing wire roller 17 and a threading roller 22. The pressing wire roller 17 is installed at one end of the fixed rod 5, and the threading roller 22 is installed at the other end of the fixed rod 5 and one end of the pushing rod 6. The end of the fixed rod 5 close to the pushing rod 6 is rotatably connected, and the output shaft of the first motor 9 penetrates the frame assembly and is fixedly connected to the other end of the fixed rod 5;

[0032] One end inside the wire threading roller 22 is provided with an oil cylinder piston 21, and a wire threading groove 23 is formed at the position of the wire threading roller 22 corresponding to the oil cylinder piston 21. Outer arc sleeves 19 and directional arc rods 20 are respectively installed on the outer wall positions of the fixing rod 5 and the lever 6 close to each other. The directional arc rod 20 is slidably connected in the outer arc sleeve 19, and a connecting spring 18 is installed at the position of the directional arc rod 20 corresponding to the inside of the outer arc sleeve 19;

[0033] The frame assembly includes a fixed frame 1, a second turntable 2 and an inner turntable 3. The center points of the fixed frame 1, the second turntable 2 and the inner turntable 3 are collinear. The second turntable 2 is located in the middle of the fixed frame 1 and the inner turntable 3, and the second turntable 2 is rotatably connected to the fixed frame 1 and the inner turntable 3. An air pump assembly 8, a first motor 9 and a second rotation assembly are arranged on the second turntable 2. A transfer roller 4 is arranged on the fixed frame 1. The second rotation assembly is located in the middle of the transfer roller 4 and the wire winding assembly. A driving gear 12 is installed at the output end of the second motor 10, and the driving gear 12 meshes with the inner wall of the second turntable 2.

[0034] Scheme description: A brief description of the wire winding process is as follows: One end of the wire is wound around the wire winding assembly and at least one turn is wound. The purpose is to fix the wire on the wire winding assembly, so that the wire can be continuously wound on the wire winding assembly during the continuous rotation of the wire winding assembly. Regarding the frame assembly, the fixed frame 1 serves as the support structure of the overall device, and the inner turntable 3 needs to rotate synchronously with the wire winding assembly, but the second turntable 2 also needs to rotate in cooperation with the fixed frame 1 and the inner turntable 3;

[0035] The key point is that the overall wire winding process is different from the conventional wire winding method: The wire body first needs to pass through the transfer roller 4. Specifically, as Figure 2 shown, the wire body is bent reversely due to the interference of the transfer roller 4 and passes through two wire threading rollers 22. Specifically, refer to Figure 6 . The wire body passes through the wire threading grooves 23 in the two wire threading rollers 22, and finally one end of the wire body is fixed on the wire winding assembly. For this, Figure 2 is used for illustration: After the overall wire body is wound to a certain length, the wire needs to be directly cut off and the wound wire needs to be replaced. For this, an AGV cart or an electric forklift and other structures can be used to remove the wound wire. This part will not be elaborated;

[0036] It should be noted that: Limited by the winding method defined by the present invention, the cutting position of the wire body is located in the middle of the wire winding assembly and the second rotation assembly. The process can be referred to Figure 6 . The wire threading roller 22 is essentially an oil cylinder structure. By quickly injecting hydraulic oil into it, the oil cylinder piston 21 is driven to move directionally. Thus, during the normal winding process, the piston oil cylinder 21 is in the initial state, and the purpose is not to directly interfere with the transmission process of the wire body;

[0037] On the contrary, during the process of cutting the wire body, it is necessary to drive the oil cylinder piston 21 to move quickly by injecting hydraulic oil. The purpose is to quickly clamp and fix the wire body located in the wire threading roller 22, so that after the wire body in a continuous stretching state is cut, the wire body will not rebound in the reverse direction due to the tensile force. For this reason, the oil cylinder piston 21 directly fixes the wire body to avoid the reverse rebound from affecting the external working environment.

[0038] Embodiment 2: Supplementary description of the wire winding assembly in Embodiment 1:

[0039] The wire winding assembly includes a transmission assembly rod 16, a cooperating sleeve 7, and a wire winding plate 14. The transmission assembly rod 16 is arranged at the output end position of the corresponding drive assembly 11. The cooperating sleeve 7 is arranged on the outer wall of the transmission assembly rod 16, and a pressure-receiving dial sleeve 15 corresponding to the wire winding plate 14 is installed outside the cooperating sleeve 7. The wire winding plates 14 are arranged in an annular array along the center point of the cooperating sleeve 7, and there is a hinged link between the wire winding plate 14 and the pressure-receiving dial sleeve 15. A through groove 13 corresponding to the wire winding plate 14 is opened on the inner turntable 3.

[0040] Scheme description: Refer to Figure 5 for description. Among them, the wire winding plate 14 is the key structure directly bearing the wire body. However, in the initial state, when the wire body is continuously wound around each wire winding plate 14, driven by the stress generated during the winding of the wire body, each wire winding plate 14 tightly contacts the pressure-receiving dial sleeve 15. In this state, the winding diameter of the wire body is relatively small. However, in actual situations, after winding to a certain extent, it is necessary to drive the cooperating sleeve 7 to move along the direction close to the inner turntable 3 by the transmission assembly rod 16. The following is an explanation of this process:

[0041] S1: The transmission assembly rod 16 not only needs to drive the cooperating sleeve 7 to rotate in a fixed direction, but also the transmission assembly rod 16 needs the ability of linear movement. Thus, it can be understood that: there is a structure such as a fixed pin between the cooperating sleeve 7 and the transmission assembly rod 16 to maintain the above-mentioned rotation ability and linear movement ability. However, the transmission assembly rod 16 is powered by the drive assembly 11. Therefore, the connection method between the transmission assembly rod 16 and the drive assembly 13 is described as follows: The transmission assembly rod 16 specifically realizes the transmission ability through a sprocket transmission structure, but the transmission assembly rod 16 can be driven to move linearly by structures such as an oil cylinder;

[0042] S2: Regarding the relevant content in S1, the transmission connection process will not be described in detail. Specifically, refer to Figure 4 , because the wire winding assembly needs to rotate synchronously with the inner turntable 3, and it is also necessary to ensure that each wire winding plate 14 moves linearly along the radius direction of the corresponding inner turntable 3. For this reason, the corresponding through grooves 13 need to be opened simultaneously to ensure the normal sliding of the wire winding plate 14;

[0043] Based on the above content, a summary description is as follows. After winding to a certain extent, the driving assembly rod 14 drives the cooperating sleeve 7 to move linearly, thereby driving each winding plate 14 to expand outward, increasing the winding diameter on this basis. Then, after winding is completed, the cooperating sleeve 7 is reset. The actual winding diameter is reduced due to the tensile force of the wound wire body, aiming to prevent the subsequent AGV cart or electric forklift from quickly removing the wound wire body on the winding assembly.

[0044] Embodiment 3: Combining Embodiment 1 and Embodiment 2 to supplement the description of the overall wire winding process:

[0045] The fixing rod 5 is arranged close to the winding assembly, and the dial rod 6 is arranged close to the transfer roller 4. The wire body first passes through the winding of the transfer roller 4 and then passes through the wire passing groove 23 to penetrate through the two wire passing rollers 22 and is finally wound on the winding assembly.

[0046] Scheme description: Referring again to Figure 2 and in conjunction with the winding method of the wire body for description. During the normal winding process, the first motor 9 does not provide support force to the fixing rod 5. Essentially, the fixing rod 5 can rotate freely on the second turntable 2. However, it should also be noted that: due to the tensile force generated during wire winding, the two wire passing rollers 22 are arranged in cooperation with the winding direction of the wire body. Specifically, the dial rod 6 can be freely aligned relative to the fixing rod 5 to ensure that the setting direction of the dial rod 6 is parallel to the straightening direction of the wire body between the winding assembly and the transfer roller 4. During this process, the fixing rod 5 can swing freely, specifically ensuring that it does not interfere with the normal winding process of the wire body;

[0047] The key lies in the process of cutting the wire body and then rewinding it. As shown in Embodiment 2, the wire body is fixed in the wire passing rollers 22 by the oil cylinder piston 21. For this, reference needs to be made to Figure 2 , it is necessary to drive the winding assembly and the fixing rod 5 to rotate directionally. Essentially, one end of the cut wire body is placed on one of the winding plates 14, and by rotating the fixing rod 5, the wire body at one end is pressed tightly on the winding plate 14 by the pressing roller 17;

[0048] And on this basis, the winding assembly and the second rotating assembly rotate synchronously for at least one circle, and the wire body at one end is tightened to ensure that the wire body at one end is wound and fixed on the winding assembly. Finally, the clamping process of the oil cylinder piston 21 on the wire body is released again to ensure the normal transmission of the wire body in the wire passing rollers 22, thereby directly completing the quick installation operation of one end of the wire body;

[0049] It should be further supplemented and explained that during the normal winding process, the lever 6 rotates slightly in the direction close to the fixed rod 5, so that the outer arc sleeve 19 and the directional arc rod 20 slide relative to each other, and the connecting spring 18 is in a compressed state. However, at the moment when the wire body is cut off, the generated tensile force first acts on the lever 6, which is specifically reflected in the rebounding process of the connecting spring 18;

[0050] The rotation process of the two-rotation assembly is described as follows: The two-rotation assembly rotates synchronously through the rotation of the two-rotation disk 2, and during the rotation of the two-rotation disk 2, the fixed rod 5 needs to rotate synchronously. The purpose is to ensure that the wire pressing roller 17 continuously presses one end of the wire body.

[0051] In summary, for the process of changing the winding during the winding process of the wire body, specifically for the large tensile force released at the moment when the wire body is cut off, a two-rotation assembly is specifically added. The two-rotation assembly includes a wire threading roller and a wire pressing roller. During the normal winding process, the wire pressing roller does not participate in the winding process of the wire. The wire threading roller cooperates with the middle transfer roller to change the winding direction of the wire body. The key lies in hydraulically pressing the wire body with the wire threading roller during the cutting action. The purpose is that the fixed rod and the lever are used as the bearing structures when the tensile force is released, so as to prevent the direct impact of the tensile force release process on the external working environment. And again, the secondary rotation process of the wire threading roller facilitates the re-threading process in the subsequent winding operation, reducing the working intensity and working time of the subsequent re-threading.

[0052] The preferred embodiments of the present invention disclosed above are only used to help explain the present invention. The preferred embodiments do not describe all the details in detail, nor limit the invention to only the specific implementation manners. Obviously, according to the content of this specification, many modifications and changes can be made.
