Description

Technical Field

[0001] This utility model relates to the field of tension adjustment technology, specifically to a tension adjustment structure for strip-shaped objects. Background Technology

[0002] In the manufacturing of DC motors, the commutator is the core component of the motor rotor. In the field of commutator production, the surface grinding quality of the copper strip directly affects the conductivity and service life of the commutator.

[0003] Currently, the polishing of the commutator copper strip surface is usually achieved using polishing belts, which have a structure with a polishing layer on one side and a smooth surface on the other. During the polishing process, the polishing layer is only allowed to contact the commutator. Therefore, existing mechanisms utilize the smooth surface of the polishing belt for transition and transmission to reduce wear on the polishing belt.

[0004] However, the tension control mechanism of existing commutator grinding devices has significant defects. Common tension control methods on the market mostly use counterweights or pneumatic tensioning: counterweight tension control relies on gravity to pull the grinding belt, but its tension value fluctuates significantly with the displacement of the counterweight, making it difficult to maintain a constant tension; although pneumatic tensioning can adjust the tension through air pressure, its tension stability cannot be guaranteed due to factors such as fluctuations in air source pressure, resulting in uneven grinding of the commutator copper strip surface.

[0005] Therefore, how to overcome the shortcomings of the existing technology mentioned above has become the subject of this utility model. Utility Model Content

[0006] The purpose of this invention is to provide a tension adjustment structure for strip-shaped objects.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A tension adjustment structure for a strip-shaped object, comprising:

[0009] The substrate is arranged vertically.

[0010] A tape feeding motor and a tape feeding reel are connected by a transmission. The tape feeding motor is fixedly installed on the base plate, and the tape feeding reel is used to feed the wound tape-shaped object.

[0011] A take-up motor and a take-up reel are connected by a drive mechanism. The take-up motor is separately disposed from the base plate. The take-up motor is used to take up the strip-shaped object.

[0012] Multiple guiding mechanisms, at least partially fixedly mounted on the substrate, are used to plan the movement path of the strip-shaped object;

[0013] The adjustment mechanism includes a tension adjustment block that can move vertically, the tension adjustment block contacting a strip to adjust the tension of the strip;

[0014] The height of the tape release reel is lower than the height of the tape take-up reel.

[0015] This application uses a strip-shaped object as an example of an abrasive belt, but is not limited thereto.

[0016] The substrate serves as the basic support structure. Other support structures can be added during actual use. The support structure is a standard feature and will not be described in detail here. The substrate is positioned vertically to avoid occupying too much space in its thickness direction and to facilitate observation of the movement of the grinding belt and the operation of the tape feeding reel.

[0017] The tape feeding motor is connected to the tape feeding reel drive, which is an existing configuration and will not be described in detail here.

[0018] In the above scheme, the unwinding reel is a direct unwinding structure for the grinding belt, and the take-up reel is a direct take-up structure for the grinding belt. The two work together to carry out the transfer and grinding operation of the grinding belt. By coordinating the unwinding motor and the take-up motor, the tension of the grinding belt can be flexibly adjusted. For example, when the tension is too high, the unwinding motor causes the unwinding reel to unwind faster, and / or the take-up motor causes the take-up reel to take up the belt at a low speed, ensuring stable grinding of the grinding belt.

[0019] The tape feeding motor is fixedly mounted on the base plate, while the tape take-up motor is separately mounted from the base plate. Based on this, see [reference needed]. Figure 1 This allows for convenient placement of the motor rotor while waiting for the workpiece to be ground.

[0020] The height of the unloading reel is lower than that of the take-up reel. This can be considered as the unloading reel being in a lower position and the take-up reel being in a higher position. This creates a vertical or inclined tension range for the grinding belt in the transmission path, making it easier to maintain the tension of the grinding belt and avoid tension instability caused by gravity.

[0021] The arrangement of multiple guiding mechanisms allows for a longer movement path of the grinding belt, thus providing a buffer time for the tension adjustment process.

[0022] The tension adjusting block applies a downward pulling force to the grinding belt by its own weight. When tension fluctuations occur in the grinding belt, the tension adjusting block can automatically adjust the tension of the grinding belt by moving up and down, thus compensating for the inability of the unloading motor and the take-up motor to adjust the tension in a timely manner.

[0023] In a further technical solution, along the thickness direction of the substrate, the tape feeding motor, the tape feeding reel, the tape taking-up motor, the tape taking-up reel, each of the guiding mechanisms, and the adjusting mechanism are located on the same side relative to the substrate.

[0024] Here's an example where the substrate's length and width are infinitely large. In this case, the feeding motor, feeding reel, take-up motor, take-up reel, guiding mechanisms, and adjusting mechanisms are all located on the same side of the substrate. This eliminates the need for double-sided processing, reducing machining and assembly difficulty. Furthermore, the grinding belts are exposed on the same side, facilitating observation and adjustment.

[0025] In some embodiments, the adjustment mechanism is not located on the same side of the substrate as the guide mechanism.

[0026] A further technical solution involves a guiding mechanism comprising a fixed post and a guide wheel. The guide wheel is rotatably mounted on the outside of the fixed post, and a first annular guide groove is provided on the guide wheel corresponding to the strip-shaped object. The first annular guide groove limits the grinding strip in the thickness direction of the substrate, preventing it from deviating from the predetermined movement path and ensuring the grinding effect.

[0027] In some embodiments, the fixed column and the guide wheel can be separated, and the guide wheel can be replaced to accommodate grinding belts of different specifications.

[0028] In some embodiments, the guide wheel and the fixed post remain relatively stationary, while the fixed post is rotatably mounted on a support structure (such as a substrate). The guide wheel can rotate relative to the substrate, thus avoiding a significant increase in frictional wear on the polishing belt.

[0029] A further technical solution involves providing a sliding groove on the substrate, with the tension adjusting block slidably assembled with the sliding groove. The tension adjusting block needs to have the characteristic of being able to move vertically, and the sliding groove is set vertically accordingly. The sliding groove restricts the degree of freedom of movement of the tension adjusting block, which is simple, convenient, low-cost, and facilitates quick disassembly and replacement of the tension adjusting block.

[0030] In a further technical solution, a slide rail is provided on the substrate, and the tension adjusting block is slidably assembled with the slide rail;

[0031] The tension adjusting block is provided with a second annular guide groove corresponding to the strip-shaped object;

[0032] Along the thickness direction of the substrate, the second annular guide groove and the slide rail are respectively located on opposite sides of the substrate.

[0033] The slide rail can restrict the movement freedom of the tension adjusting block on its own, or it can be used in conjunction with the slide groove. The latter will be explained here: When only the slide groove is used for restriction, the accuracy is not easy to control, the tension adjusting block is at risk of rotation, and the control of the movement freedom of the tension adjusting block is not perfect. With the help of the slide rail, the tension adjusting block is regarded as a slider. The assembly technology of slider and slide rail is relatively mature, which can accurately restrict the tension adjusting block to move only vertically.

[0034] When both slide rails and slide grooves are installed, the slide groove serves two purposes: firstly, it acts as an auxiliary limit, especially when there are problems with the sliding assembly of the tension adjustment block and the slide rail; secondly, it provides a channel for the tension adjustment block to pass through the base plate.

[0035] Along the thickness direction of the substrate, the second annular guide groove and the slide rail are located on opposite sides of the substrate. At this time, the tension adjustment block can be observed from both sides of the substrate, improving the ease of observation.

[0036] Further technical solutions also include:

[0037] A tension measuring wheel is movably mounted on the base plate and is configured to cooperate with part of the guide mechanism to contact the strip-shaped object and transmit tension information.

[0038] A tension sensor, connected to the tension measuring wheel, is used to detect the signal generated by the tension measuring wheel due to the force applied.

[0039] See Figure 3 The tension sensor, tension measuring wheel, and two guide mechanisms on both sides together form a tension measurement structure, compensating for the inability of the unwinding and take-up motors to adjust the tension in a timely manner. In one specific implementation of this tension measurement structure, the tension measuring wheel is hinged between the two guide mechanisms via a swing arm. The tension measuring wheel and the two guide mechanisms form a V-shaped material transport channel. When a strip passes through, the tension change causes the tension measuring wheel to swing around the hinge point. The tension sensor, installed at the connection between the swing arm and the substrate, detects the pressure or displacement changes generated by this swing and converts the signal into an electrical signal, outputting it to the control system to achieve real-time monitoring and feedback adjustment of the tension. For example, in common film winding equipment, the film sequentially passes around a directional wheel, a measuring wheel, and another directional wheel, forming a fixed path. The swing angle of the measuring wheel's swing arm is linearly related to the film tension, and the sensor accurately calculates the tension value accordingly. This tension control method based on directional wheel positioning, measuring wheel swing, and sensor detection is common knowledge in the field, and its specific structure and working principle will not be detailed here.

[0040] The terms "first," "second," etc., used in this article do not specifically refer to order or sequence, nor are they intended to limit this case; they are merely used to distinguish components or operations described using the same technical terms.

[0041] The terms "connection" or "positioning" as used in this article can refer to two or more components or devices making direct physical contact with each other, or making indirect physical contact with each other, or to two or more components or devices operating or moving with each other.

[0042] The terms “include,” “including,” and “have” used in this article are all open-ended, meaning they include but are not limited to.

[0043] Unless otherwise specified, the terms used herein generally have their ordinary meaning in the context of the art, the subject matter, and the specific context. Certain terms used to describe this case will be discussed below or elsewhere in this specification to provide additional guidance to those skilled in the art in describing the case.

[0044] The terms “front,” “back,” “up,” “down,” “left,” and “right” used in this article are directional terms. In this case, they are only used to describe the positional relationship between the structures and are not intended to limit the specific direction of the protection scheme or its actual implementation.

[0045] The working principle and advantages of this utility model are as follows:

[0046] The unwinding reel is the direct unwinding structure for the grinding belt, and the take-up reel is the direct take-up structure. Together, they perform the grinding belt transfer and grinding operation. Through the coordination of the unwinding motor and the take-up motor, the tension of the grinding belt can be flexibly adjusted. For example, when the tension is too high, the unwinding motor causes the unwinding reel to unwind faster, and / or the take-up motor causes the take-up reel to rewind at a low speed (deceleration), ensuring stable grinding and avoiding uneven grinding of the commutator copper strip surface.

[0047] The feeding motor is fixedly mounted on the base plate, while the take-up motor is set separately from the base plate, which facilitates the placement of the motor rotor to wait for the grinding workpiece.

[0048] The height of the unloading reel is lower than that of the take-up reel. This can be considered as the unloading reel being in a lower position and the take-up reel being in a higher position. This creates a vertical or inclined tension range for the grinding belt in the transmission path, making it easier to maintain the tension of the grinding belt and avoid tension instability caused by gravity.

[0049] The arrangement of multiple guiding mechanisms allows for a longer movement path of the grinding belt, thus providing a buffer time for the tension adjustment process.

[0050] The tension adjusting block applies a downward pulling force to the grinding belt by its own weight. When tension fluctuations occur in the grinding belt, the tension adjusting block can automatically adjust the tension of the grinding belt by moving up and down, thus compensating for the inability of the unloading motor and the take-up motor to adjust the tension in a timely manner.

[0055] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0056] Example: The present invention will be clearly described below with illustrations and detailed description. Any person skilled in the art who understands the examples of the present invention can make changes and modifications based on the technology taught in the present invention without departing from the spirit and scope of the present invention.

[0058] See Figures 1-3 A tension adjustment structure for a strip-shaped object, comprising:

[0059] Substrate 1 is arranged vertically;

[0060] The tape feeding motor 2 and tape feeding reel 3 are connected by a transmission. The tape feeding motor 2 is fixedly installed on the base plate 1, and the tape feeding reel 3 is used to feed the rolled tape object 100.

[0061] The winding motor 4 and the winding reel 5 are connected by a drive. The winding motor 4 is separately disposed from the base plate 1. The winding motor 4 is used to wind up the strip-shaped object 100.

[0062] Multiple guiding mechanisms 6 are at least partially fixedly installed on the base plate 1 for planning the movement path of the strip-shaped object 100;

[0063] The adjustment mechanism 7 includes a tension adjustment block 71 that can move vertically, the tension adjustment block 71 contacting the strip 100 to adjust the tension of the strip 100;

[0064] The height of the tape release reel 3 is lower than the height of the tape take-up reel 5.

[0065] This application uses a strip-shaped object 100 as an example of a grinding belt, and the grinding object of the grinding belt is described using the commutator copper strip of the motor rotor 200, but it is not limited to this.

[0066] The substrate 1 serves as the basic support structure. In actual use, other support structures can be added. The support structure is a conventional setup and will not be described in detail here. The substrate 1 is arranged vertically to avoid occupying too much space in its own thickness direction and to facilitate observation of the movement of the grinding belt and the operation of structures such as the tape feeding tray 3.

[0067] The tape feeding motor 2 is connected to the tape feeding reel 3 via a transmission. This part is an existing configuration and will not be described in detail here.

[0068] The unwinding reel 3 is a direct unwinding structure for the grinding belt, and the take-up reel 5 is a direct take-up structure for the grinding belt. Together, they perform the grinding belt transfer and grinding operation. Through the cooperation of the unwinding motor 2 and the take-up motor 4, the tension of the grinding belt can be flexibly adjusted. For example, when the tension is too high, the unwinding motor 2 causes the unwinding reel 3 to unwind faster, and / or the take-up motor 4 causes the take-up reel 5 to take up the belt at a low speed, ensuring stable grinding of the grinding belt.

[0069] The tape feeding motor 2 is fixedly mounted on the base plate 1, while the tape take-up motor 4 is separately mounted from the base plate 1. Based on this, see Appendix Figure 1 This allows for convenient placement of the motor rotor 200, which is ready for grinding.

[0070] The height of the unloading reel 3 is lower than that of the take-up reel 5. This can be considered as the unloading reel 3 being in a lower position and the take-up reel 5 being in a higher position. This creates a vertical or inclined tension range for the grinding belt in the transmission path, making it easier to maintain the tension of the grinding belt and avoid tension instability due to gravity.

[0071] The arrangement of multiple guide mechanisms 6 allows for a longer movement path of the grinding belt, thus providing a buffer time for the tension adjustment process.

[0072] The tension adjusting block 71 applies a downward pulling force to the grinding belt by its own weight. When the tension of the grinding belt fluctuates, the tension adjusting block 71 can automatically adjust the tension of the grinding belt by moving up and down, which makes up for the inability of the unloading motor 2 and the take-up motor 4 to adjust the tension in time.

[0073] In this embodiment, along the thickness direction of the substrate 1, the tape feeding motor 2, the tape feeding reel 3, the tape taking-up motor 4, the tape taking-up reel 5, each of the guide mechanisms 6 and the adjustment mechanism 7 are located on the same side relative to the substrate 1.

[0074] Here's an example where the length and width of substrate 1 are infinitely large. In this case, the feeding motor 2, feeding reel 3, taking-up motor 4, taking-up reel 5, each guiding mechanism 6, and the adjusting mechanism 7 are all located on the same side of substrate 1. On one hand, this eliminates the need for double-sided processing of substrate 1, reducing machining and assembly difficulty; on the other hand, the grinding belt is exposed on the same side, facilitating observation and adjustment.

[0075] See Figure 1 In some embodiments, only the tape feeding reel 3, the tape take-up reel 5, and each guide mechanism 6 are located on the same side of the substrate 1. Taking the tape feeding motor 2 as an example, the tape take-up motor 4 is described with reference to this: at least a portion of the tape feeding motor 2 is located on the other side of the substrate 1, so that the tape feeding reel 3 can be close to the substrate 1, avoiding the need for structures such as the fixing post 61 to have a large length dimension.

[0076] See Figure 3 In this embodiment, the guiding mechanism 6 includes a fixed post 61 and a guide wheel 62. The guide wheel 62 is rotatably mounted on the outside of the fixed post 61, and a first annular guide groove 621 is provided on the guide wheel 62 corresponding to the strip-shaped object 100. The first annular guide groove 621 limits the grinding strip in the thickness direction of the substrate 1, preventing it from deviating from the predetermined movement path and ensuring the grinding effect.

[0077] In some embodiments, the fixing post 61 and the guide wheel 62 can be separated, and the guide wheel 62 can be replaced to accommodate grinding belts of different specifications.

[0078] In some embodiments, the guide wheel 62 remains relatively stationary with respect to the fixed post 61, which is rotatably mounted on the support structure (such as the substrate 1). The guide wheel 62 can rotate relative to the substrate 1, thus avoiding a significant increase in frictional wear of the polishing belt.

[0079] See Figure 1 In this embodiment, the substrate 1 is provided with a sliding groove 11, and the tension adjusting block 71 is slidably assembled with the sliding groove 11. The tension adjusting block 71 needs to have the characteristic of being able to move vertically. The sliding groove 11 is set vertically, and the sliding groove 11 restricts the degree of freedom of movement of the tension adjusting block 71. This is simple, convenient, low-cost, and facilitates quick disassembly and replacement of the tension adjusting block 71.

[0080] See Figure 2 In this embodiment, the substrate 1 is provided with a slide rail 8, and the tension adjusting block 71 is slidably assembled with the slide rail 8;

[0081] The tension adjusting block 71 is provided with a second annular guide groove 711 corresponding to the strip-shaped object 100;

[0082] Along the thickness direction of the substrate 1, the second annular guide groove 711 and the slide rail 8 are respectively located on the symmetrical sides of the substrate 1.

[0083] The slide rail 8 can restrict the movement freedom of the tension adjusting block 71 independently, or it can be used in conjunction with the slide groove 11. The latter will be explained here: when only the slide groove 11 is used for restriction, the accuracy is not easy to control, the tension adjusting block 71 is at risk of rotation, and the control of the movement freedom of the tension adjusting block 71 is not perfect. With the help of the slide rail 8, the tension adjusting block 71 is regarded as a slider. The assembly technology of slider and slide rail 8 is relatively mature, which can accurately restrict the tension adjusting block 71 to move only vertically.

[0084] When both slide rail 8 and slide groove 11 are provided, slide groove 11 serves two purposes: firstly, it acts as an auxiliary limit, especially in cases where there are problems with the sliding assembly of tension adjusting block 71 and slide rail 8; secondly, it provides a channel for tension adjusting block 71 to pass through base plate 1.

[0085] Along the thickness direction of substrate 1, the second annular guide groove 711 and the slide rail 8 are located on opposite sides of substrate 1. At this time, the tension adjustment block 71 can be observed from both sides of substrate 1, improving the ease of observation.

[0086] See Figures 1-3 In this embodiment, it also includes:

[0087] Tension measuring wheel 9 is movably mounted on the base plate 1 and is configured to cooperate with part of the guide mechanism 6 for contacting the strip object 100 and transmitting tension information.

[0088] Tension sensor 10 is connected to tension measuring wheel 9 and is used to detect the signal generated by the tension measuring wheel 9 due to force.

[0089] See Figure 3The tension sensor 10, tension measuring wheel 9, and two guide mechanisms 6 on both sides together form a tension measuring structure, compensating for the inability of the unloading motor 2 and the take-up motor 4 to adjust the tension in a timely manner. In one specific embodiment of this tension measuring structure, the tension measuring wheel 9 is hinged between the two guide mechanisms 6 via a swing arm. The tension measuring wheel 9 and the two guide mechanisms 6 form a V-shaped material transport channel. When the strip object 100 passes through, the tension change causes the tension measuring wheel 9 to swing around the hinge point. The tension sensor 10, installed at the connection between the swing arm and the substrate 1, detects the pressure or displacement change generated by this swing and converts the signal into an electrical signal, outputting it to the control system to achieve real-time monitoring and feedback adjustment of the tension. For example, in common film winding equipment, the film sequentially passes around the directional wheel, the measuring wheel, and another directional wheel to form a fixed path. The swing angle of the measuring wheel's swing arm is linearly related to the film tension, and the sensor accurately calculates the tension value accordingly. This tension control method based on directional wheel positioning, measuring wheel swing, and sensor detection is common knowledge in the field, and its specific structure and working principle will not be detailed here. The structure of the tension measuring wheel 9 can be referenced from the setting of the guide mechanism 6.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
