Description

Technical Field

[0001] The utility model belongs to the technical field of winding deviation rectification, and particularly relates to a balance structure with a deviation rectification function and a coding device. Background Art

[0002] Generally, when winding materials, the coil diameter of the coil will continuously change, and the tension of the coil will continuously change with the change of the coil diameter. In this case, if the tension of the coil is not controlled, the coil will have wrinkles, looseness, thickness changes, etc. In severe cases, the coil may break.

[0003] However, in the existing winding technologies, the structures of the corresponding deviation rectification devices are relatively complex. Either the space occupied by the deviation rectification operation process is large, making it difficult to meet the requirements of a simple and compact structure, or the deviation rectification action appears to be rather cumbersome.

[0004] Based on the above difficulties, there is an urgent need for a deviation rectification balance structure with a simple structure and a compact size. Summary of the Utility Model

[0005] In order to solve the deficiencies of the existing technologies, the utility model provides a balance structure with a deviation rectification function. Through the combined design of a deviation rectification mechanism and an induction mechanism, when the induction mechanism senses the deviation of the material, the driving mechanism is used to drive the deviation rectification mechanism to perform a left-lifting or right-lifting action, so that different tensions are applied to both ends of the material, and then the material is adjusted to a balanced state to ensure the regularity of the material winding. By using the left-right lifting action of the deviation rectification mechanism, the upper and lower spaces of the balance structure are effectively utilized, meeting the requirement of small space occupation during the winding deviation rectification action, thereby improving the space utilization rate. Moreover, by arranging the deviation rectification mechanism and the driving mechanism in parallel and setting the position of the induction mechanism, the overall structure design is simple and compact, meeting the lightweight of the overall structure and realizing a relatively flexible deviation rectification action. The utility model provides a coding device, which effectively ensures the balance of the winding process, improves the winding quality, and ensures the smoothness of the winding by using the balance structure to control and adjust the winding process.

Detailed implementation manners

[0037] To make the purpose, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The described embodiments are some but not all of the embodiments of the present utility model.

[0038] Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the claimed present utility model, but merely represents selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0039] Embodiment 1:

[0040] Please refer to the attached Figure 1, A balance structure with a deviation rectification function of the present utility model includes a driving mechanism 1, a deviation rectification mechanism 2, and an induction mechanism 3. The deviation rectification mechanism 2 is drivingly connected to the driving mechanism 1, and the driving mechanism 1 and the deviation rectification mechanism 2 are arranged in parallel; the induction mechanism 3 is connected to the lower end of the driving mechanism 1 and is correspondingly arranged with the lower end of the deviation rectification mechanism 2; wherein, the deviation rectification mechanism 2 includes a guiding component 21 and a deviation rectification component 22. One side of the guiding component 21 is connected to the side of the driving mechanism 1 close to the deviation rectification mechanism 2, and the other side of the guiding component 21 is connected to the deviation rectification component 22.

[0041] Specifically, the driving mechanism 1 is used to drive the deviation rectification mechanism 2 to act and is the power source of the deviation rectification mechanism 2.

[0042] The induction mechanism 3 is used to sense the positions on both sides of the material 4, and then judge whether the material 4 deviates during the winding process through the control center, transmit the corresponding data to the control center, and convert the deviation signal of the material 4 into a signal for the driving mechanism 1 to act through the control center, and then correspondingly drive the deviation rectification mechanism 2 to act, so as to balance the material 4 and adjust the material 4 to the normal conveying state.

[0043] The deviation rectification mechanism 2 is used to adjust the offset material 4 to the state of normal position transmission, and the actions it can take are to lift on the left side or the right side. It can be understood that, please refer to the attached Figures 2-3 , wherein, Figure 2 The arrow in indicates the conveying direction of the material 4. Figure 3 In, L represents the left side and R represents the right side. When observing from the direction from one end of the material 4 to the winding end, if the material 4 shows a phenomenon of moving forward to the left, the deviation rectification mechanism 2 performs a right-side lift, thereby increasing the tension at the right end of the material 4, so that the material 4 is adjusted to a balanced state; please refer to the attached Figures 4-5 , wherein, Figure 4 The arrow in indicates the conveying direction of the material 4. Figure 5 In, L represents the left side and R represents the right side. If the material 4 shows a phenomenon of moving forward to the right, the deviation rectification mechanism 2 performs a left-side lift, thereby increasing the tension at the left end of the material 4, so that the material 4 is adjusted to a balanced state, and then the deviation rectification action is completed. Among them, the balanced state means that the material 4 can maintain a straight-ahead conveyance in the transmission path from one end of the material 4 to the winding end.

[0044] In this embodiment, the deviation rectification action of the balance structure is as follows: First, the induction mechanism 3 senses the positions on both sides of the material 4 and judges whether the material 4 deviates during the winding process through the control center. If it is judged that the material 4 deviates, the control center converts the deviation signal into an action signal and then starts the driving mechanism 1, thereby driving the deviation rectification mechanism 2 to act, that is, the deviation rectification component 22 performs a left-side lift action or a right-side lift action along the guiding component 21, so that different tensions are applied to both ends of the material 4, and then the material 4 is adjusted to a balanced state, ensuring the regularity of the winding of the material 4.

[0045] Through the setting of the above structure, by using the left and right lifting actions of the deviation rectifying mechanism 2, the upper and lower spaces of the balance structure are effectively utilized, meeting the requirement of small occupied space during the winding deviation rectifying action, thereby improving the space utilization rate. Moreover, by arranging the deviation rectifying mechanism 2 and the driving mechanism 1 side by side, and setting the position of the sensing mechanism 3, the overall structure design is simple and compact, meeting the lightweight of the overall structure and enabling the deviation rectifying action to be relatively flexible.

[0046] Please refer to the appendix Figure 6 , the deviation rectifying component 22 includes a deviation rectifying frame 221, a first deviation rectifying shaft 222, and a second deviation rectifying shaft 223. The first deviation rectifying shaft 222 is connected to the upper end of the deviation rectifying frame 221, and the second deviation rectifying shaft 223 is connected to the lower end of the deviation rectifying frame 221. The first deviation rectifying shaft 222 and the second deviation rectifying shaft 223 are arranged in parallel and correspondingly. Among them, the driving mechanism 1 is fixedly connected to the deviation rectifying frame 221. Preferably, one end of the first deviation rectifying shaft 222 away from the winding is the first end, and one end of the second deviation rectifying shaft 223 close to the winding is the second end, that is, the material 4 moves from the first deviation rectifying shaft 222 to the second deviation rectifying shaft 223.

[0047] The guiding component 21 includes a first guiding member 211, a second guiding member 212, a first sliding block 213, and a second sliding block 214. The first sliding block 213 is movably connected to the first guiding member 211, and the second sliding block 214 is movably connected to the second guiding member 212. Among them, the first guiding member 211 and the second guiding member 212 are symmetrically arranged and are both fixedly connected to the driving mechanism 1. The first sliding block 213 and the second sliding block 214 are both connected to the deviation rectifying frame 221. Preferably, one end of the first guiding member 211 close to the sensing mechanism 3 is inclined towards the second guiding member 212, and one end of the second guiding member 212 close to the sensing mechanism 3 is inclined towards the first guiding member 211. The first guiding member 211 and the second guiding member 212 form an inverted V shape.

[0048] In the combined design of the deviation rectifying component 22 and the guiding component 21 in this embodiment, the specific movement of the deviation rectifying mechanism 2 is as follows: When the deviation rectifying mechanism 2 needs to perform a left-lifting action, first, the driving mechanism 1 drives the deviation rectifying frame 221 to move to the left. The first sliding block 213 connected to the deviation rectifying frame 221 moves in the left direction of the first guiding member 211, and the second sliding block 214 moves in the left direction of the second guiding member 212. And through the first guiding member 211 and the second guiding member 212 in an inverted V shape, the first sliding block 213 drives the deviation rectifying frame 221 to move upward along the upper part of the first guiding member 211, so that the left ends of the first deviation rectifying shaft 222 and the second deviation rectifying shaft 223 move upward; while the second sliding block 214 drives the deviation rectifying frame 221 to move downward along the lower part of the second guiding member 212, so that the right ends of the first deviation rectifying shaft 222 and the second deviation rectifying shaft 223 move downward, that is, the left-lifting is realized. Conversely, the right-lifting can be realized. The overall structure design is ingenious and simple, with strong practicability, effectively meeting the lightweight of the overall structure and improving the flexibility of the deviation rectifying action.

[0049] Please refer to the appendix Figure 7 , the sensing mechanism 3 includes a support member 31, a first sensing component 32, and a second sensing component 33. The support member 31 is fixedly connected to the lower end of the driving mechanism 1. The first sensing component 32 is connected to one end of the support member 31, and the second sensing component 33 is connected to the other end of the support member 31. Among them, the first sensing component 32 is used to sense and receive the position signal of one edge of the material 4, and the second sensing component 33 is used to sense and receive the position signal of the other edge of the material 4. Through the setting of the sensing mechanism 3, the specific position situation of the material 4 during the transmission process can be understood in a timely manner, and the corresponding signals are received and converted by the control center. In the case of a small deviation, it can be discovered and corrected in a timely manner, realizing dynamic deviation rectification and effectively ensuring the quality of winding.

[0050] Preferably, the first sensing component 32 includes a first moving member 321, a first locking screw 322, and a first sensor 323. The first moving member 321 is movably connected to the support member 31. The first sensor 323 is fixedly connected to the lower end of the first moving member 321, and the first locking screw 322 is connected to the first moving member 321. Among them, the first sensor 323 can be realized by any existing method such as infrared rays or lasers.

[0051] The second sensing component 33 includes a second moving member 331, a second locking screw 332, and a second sensor 333. The second moving member 331 is movably connected to the support member 31. The second sensor 333 is fixedly connected to the lower end of the second moving member 331, and the second locking screw 332 is connected to the second moving member 331. Among them, the second sensor 333 can be realized by any existing method such as infrared rays or lasers.

[0052] Through the specific structural design of the above-mentioned first sensing component 32 and second sensing component 33, the width between the first sensing component 32 and the second sensing component 33 can be adjusted, so that it can be applicable to the deviation rectification actions of materials 4 of different sizes. When the width of the material 4 is relatively large, the distance between the first inductor 323 and the second inductor 333 is widened, that is, the first locking screw 322 and the second locking screw 332 are loosened respectively, so that the first inductor 323 can move on the support 31 through the first moving member 321, and the second inductor 333 can move on the support 31 through the second moving member 331, thereby widening the distance between the first inductor 323 and the second inductor 333. After the distance adjustment is completed, the first moving member 321 and the second moving member 331 are stably fixed on the support 31 through the first locking screw 322 and the second locking screw 332 respectively. On the contrary, the distance between the first inductor 323 and the second inductor 333 is narrowed. It can adapt to the induction deviation rectification of materials 4 of various sizes, and has a wide application range.

[0053] Please refer to the appendix Figures 8-9 As shown in the figure, the driving mechanism 1 includes a housing 11, a driving component 12 and a connecting body 13. The driving component 12 is arranged in the housing 11. An activity hole 111 is arranged on one side of the housing 11 close to the deviation rectification component 22. The connecting body 13 is connected between the driving component 12 and the deviation rectification component 22 and penetrates through the activity hole 111.

[0054] Specifically, the driving component 12 includes a motor 121, a lead screw 122 and a moving block 123. The motor 121 is drivingly connected to the lead screw 122. The moving block 123 is movably connected through the lead screw 122, and the side of the moving block 123 close to the activity hole 111 is connected to the connecting body 13; Guide rods 124 are symmetrically arranged on both sides of the lead screw 122 and are movably connected to the moving block 123.

[0055] In the driving mechanism 1 of this embodiment, the specific action is: when it is sensed that the material 4 is offset, the motor 121 is started to drive the lead screw 122 to move, thereby driving the moving block 123 to move left or right. The deviation rectification frame 221 moves left or right along with the moving block 123 through the connecting body 13, and then the driving process is completed. The overall driving process has strong rhythm, the process operation is compact, and its structural design is simple, which can greatly reduce energy loss.

[0056] Embodiment 2:

[0057] The difference between this embodiment and Embodiment 1 is, please refer to Figure 10, the driving component 12 of this embodiment further includes a guide rod 124. The guide rod 124 is symmetrically connected to the housing 11 with the lead screw 122 as the center and is movably connected to the moving block 123. Through the arrangement of the guide rod 124, the balance ability of the movement of the moving block 123 can be increased, effectively ensuring the stability of the rectification process and the rectification quality.
