Description

Technical Field

[0001] This utility model relates to the technical field of insulating paper forming equipment, and in particular to an insulating paper guiding and tensioning mechanism. Background Technology

[0002] In the field of motor manufacturing, stator insulation paper is a key component that ensures the insulation performance of motor stator windings. Its forming quality is directly related to the operational safety and service life of the motor. In order to meet the stator assembly requirements, the insulation paper needs to be formed into a specific shape and structure. This process relies on specialized insulation paper forming equipment.

[0003] During the forming process, it is essential to ensure that the insulating paper remains under stable tension on the forming equipment and is guided precisely without deviation. Simultaneously, precise coordination between paper feeding and forming processes is crucial. However, existing stator insulating paper forming equipment still has some issues with its guiding and tensioning technology. Currently, tension control for stator insulating paper largely relies on pneumatic, hydraulic, or electrical control methods used in general insulating paper processing. This is not only structurally redundant and costly, but also prone to problems due to the thinness and unique shape of stator insulating paper. Such active control can lead to response lag or accuracy deviations, resulting in excessive local tension causing tensile deformation, insulation layer damage, or insufficient tension causing loosening, wrinkles, and dimensional deviations. This severely impacts the forming quality of the insulating paper. Furthermore, existing equipment lacks the ability to detect paper feeding tension, leading to overfeeding or underfeeding. Overfeeding causes the insulating paper to accumulate and loosen, while underfeeding causes a sudden increase in tension, resulting in tearing. This not only increases the scrap rate but also disrupts the production process. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing an insulating paper guiding and tensioning mechanism to solve the problems of complex tension control, insufficient guidance, and poor paper feeding coordination in existing insulating paper forming equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An insulating paper guiding and tensioning mechanism includes an insulating paper forming device. The insulating paper forming device includes a guide mounting plate. The guide mounting plate is provided with a tension adjusting component, a detection component for detecting the position of the tension adjusting component, and an auxiliary roller for guiding the insulating paper. The tension adjusting component applies tension to the insulating paper by its own weight. The detection component controls the start and stop of the paper feeding action based on the position trigger signal of the tension adjusting component.

[0006] Preferably, the guide mounting plate has a movable hole, and the tension adjusting component is installed at the movable hole. The tension adjusting component includes a movable block, an adjusting cylinder, and at least two guide rods. The upper and lower ends of the guide rods are provided with mounting plates. The mounting plates are fixedly installed on the guide mounting plate and are located at the upper and lower ends of the movable hole, respectively. The movable block is slidably sleeved on the guide rod, and the adjusting cylinder is rotatably mounted on the movable block.

[0007] Preferably, the movable block has a mounting hole corresponding to the guide rod, and a sliding bushing is fixed in the mounting hole. The sliding bushing is movably sleeved on the guide rod. The sliding bushing reduces the direct friction between the movable block and the guide rod, ensuring that the movable block slides smoothly without jamming, extending the service life of the component, and ensuring the stability of tension adjustment.

[0008] Preferably, the movable block has an installation groove on its outward side, and the adjusting cylinder is rotatably mounted in the installation groove via a shaft. One end of the shaft is located in the installation groove and is fixedly connected to the movable block, thus limiting the adjustment cylinder to be rotatably mounted on the movable block via the shaft. This allows the adjusting cylinder to rotate synchronously with the insulation paper when it comes into contact with the insulation paper, reducing frictional damage to the insulation paper and ensuring smooth transmission of the insulation paper during tensioning.

[0009] Preferably, the tension adjusting component further includes a connecting plate, which is fixedly connected to the side of the moving block away from the shaft. The connecting plate extends with a trigger end for triggering the detection component. The detection component includes a fixed plate and a detection switch mounted on the fixed plate. The detection switch can be a slotted photoelectric sensor when in use.

[0010] Preferably, there are two detection elements, which are respectively located on the upper and lower sides of the guide mounting plate away from the mounting base plate. They are used to detect the upper and lower limits of the tension adjustment element. By detecting the limit positions of the tension adjustment element by the upper and lower detection elements, the paper feeding start and stop can be accurately triggered, avoiding the loosening of the insulation paper caused by excessive paper feeding or the tearing of the insulation paper caused by insufficient paper feeding, thus ensuring the continuity of production.

[0011] Preferably, there are two auxiliary rollers, which are arranged side by side on the left and right sides of the moving hole and above the insulating paper. The insulating paper passes through the top of the two auxiliary rollers and through the bottom of the adjusting cylinder, thus clarifying the layout of the auxiliary rollers and the transmission path of the insulating paper. The upper side of the insulating paper is guided by the auxiliary rollers, and the lower side of the adjusting cylinder is tensioned to form a stable tension adjustment path.

[0012] Preferably, the tension adjusting component further includes a protective component, which is installed above the mounting plate located below. The protective component is an elastic protective ring. When the adjusting cylinder drives the moving block to slide down to near the lowest point, the bottom of the moving block will contact the protective component above the mounting plate below. The protective component absorbs the impact force through its own elastic deformation, preventing the moving block from having a hard collision with the mounting plate, thereby protecting the component from damage and extending the service life of the mechanism.

[0013] Compared with the prior art, the present invention has the following beneficial effects: This invention utilizes a tension adjustment component that tensions the insulating paper using its own weight, eliminating the need for complex pneumatic, hydraulic, or electrical control systems. This prevents paper stretching, deformation, or loosening, ensuring stable molding quality. The sliding bushing reduces friction between the moving block and the guide rod, ensuring smooth movement and extending component life. The rotating adjustment cylinder contacts the insulating paper, reducing paper damage. Two detection components precisely trigger the paper feeding start and stop, preventing excessive loosening or insufficient tearing, ensuring continuous production. Furthermore, the elastic protective component adapts to the mounting plate below, buffering the impact of the falling moving block and preventing hard collisions, effectively improving the mechanism's adaptability, ease of use, and production reliability.

[0021] Example: Please see Figure 1-5 An insulating paper guiding and tensioning mechanism includes an insulating paper forming device, which includes a guide mounting plate 1. The guide mounting plate 1 is provided with a tension adjusting component 3, a detection component 4 for detecting the position of the tension adjusting component 3, and an auxiliary roller 2 for guiding the insulating paper. The tension adjusting component 3 applies tension to the insulating paper by its own weight. The detection component 4 controls the start and stop of the paper feeding action based on the position trigger signal of the tension adjusting component 3.

[0022] The guide mounting plate 1 has a movable hole 11. The tension adjusting component 3 is installed in the movable hole 11. The tension adjusting component 3 includes a movable block 33, an adjusting cylinder 36 and at least two guide rods 31. The upper and lower ends of the guide rods 31 are provided with mounting plates 32. The mounting plates 32 are fixedly installed on the guide mounting plate 1 and are located at the upper and lower ends of the movable hole 11 respectively. The movable block 33 is slidably sleeved on the guide rod 31, and the adjusting cylinder 36 is rotatably mounted on the movable block 33.

[0023] The movable block 33 has a mounting hole 331 corresponding to the guide rod 31. A sliding bushing 34 is fixed in the mounting hole 331. The sliding bushing 34 is movably sleeved on the guide rod 31. The sliding bushing 34 reduces the direct friction between the movable block 33 and the guide rod 31, ensuring that the movable block 33 slides smoothly without jamming, extending the service life of the component, and ensuring the stability of tension adjustment.

[0024] The movable block 33 has an installation groove 332 on its outward side. The adjusting cylinder 36 is rotatably mounted in the installation groove 332 via the shaft 35. One end of the shaft 35 is located in the installation groove 332 and is fixedly connected to the movable block 33. This limits the adjustment cylinder 36 to be rotatably mounted on the movable block 33 via the shaft 35, so that when the adjusting cylinder 36 comes into contact with the insulating paper, it can rotate synchronously with the transmission of the insulating paper, reducing frictional damage to the insulating paper and ensuring smooth transmission of the insulating paper during the tensioning process.

[0025] The tension adjusting component 3 also includes a connecting plate 37, which is fixedly connected to the side of the moving block 33 away from the shaft 35. A trigger end 371 for triggering the detection component 4 extends from the connecting plate 37. The detection component 4 includes a fixed plate 41 and a detection switch 42 mounted on the fixed plate 41. The detection switch 42 can be a slotted photoelectric sensor when in use.

[0026] Two detection elements 4 are provided, which are respectively located on the upper and lower sides of the guide mounting plate 1 away from the mounting base plate 32. They are used to detect the upper and lower limits of the tension adjustment element 3. By detecting the limit positions of the tension adjustment element 3 through the upper and lower detection elements 4, the paper feeding start and stop are accurately triggered, avoiding the loosening of the insulation paper caused by excessive paper feeding or the tearing of the insulation paper caused by insufficient paper feeding, thus ensuring the continuity of production.

[0027] Two auxiliary rollers 2 are provided, which are arranged side by side on the left and right sides of the moving hole 11 and above the insulating paper. The insulating paper passes through the top of the two auxiliary rollers 2 and through the bottom of the adjusting cylinder 36. The layout of the auxiliary rollers 2 and the transmission path of the insulating paper are clearly defined. The upper side of the insulating paper is guided by the auxiliary rollers 2, and the lower side of the adjusting cylinder 36 is tensioned to form a stable tension adjustment path.

[0028] The tension adjusting component 3 also includes a protective component 38, which is installed above the mounting plate 32 located below. The protective component 38 is an elastic protective ring. When the adjusting cylinder 36 drives the moving block 33 to slide down to near the lowest point, the bottom of the moving block 33 will contact the protective component 38 above the mounting plate 32 below. The protective component 38 absorbs the impact force through its own elastic deformation, preventing the moving block 33 from having a hard collision with the mounting plate 32, thereby protecting the components from damage and extending the service life of the mechanism.

[0029] When the subsequent processes of the insulating paper forming equipment, such as the outward feeding mechanism after forming, pull the insulating paper outward, the length of the insulating paper on the transmission path is shortened due to continuous pulling. At this time, the insulating paper will exert an upward pulling force on the adjusting cylinder 36. Since the adjusting cylinder 36 is fixedly connected to the moving block 33 through the shaft 35, and the moving block 33 is movably sleeved on the guide rod 31 through the sliding bushing 34, this pulling force will drive the adjusting cylinder 36 and the moving block 33 to slide upward along the guide rod 31. During this process, the adjusting cylinder 36 always relies on its own weight and the pulling force of the insulating paper to form a dynamic balance. If the tension of the insulating paper increases slightly, the adjusting cylinder 36 will move slightly upward to release some tension. If the tension decreases slightly, the adjusting cylinder 36 will move slightly downward to supplement the tension, thereby ensuring that the insulating paper is always in a stable tension state during the transmission process, avoiding stretching deformation or loosening. As the formed insulating paper is rapidly fed out, the adjusting cylinder 36 drives the moving block 33 to move upward continuously. The connecting plate 37, which is fixedly connected to the moving block 33, moves upward synchronously. The trigger end 371 on the connecting plate 37 also moves upward accordingly. When the amount of insulating paper fed out reaches the upper limit, that is, when the amount of insulating paper remaining on the transmission path is close to insufficient, the adjusting cylinder 36 is pulled to the highest point. At this time, the trigger end 371 just contacts the detection switch 42 on the upper side of the guide mounting plate 1, triggering the detection switch 42 to send a signal, controlling the front-end paper feeding mechanism to immediately stop feeding paper, preventing the insulating paper from tearing due to a sudden increase in force caused by untimely paper feeding. After the paper feeding mechanism stops, the subsequent processes of the forming equipment continue to release the formed insulating paper. The length of the insulating paper on the transmission path gradually increases, and the upward pull on the adjusting cylinder 36 weakens. At this time, the adjusting cylinder 36 begins to slide downward along the guide rod 31 under its own gravity. The moving block 33, the connecting plate 37, and the trigger end 371 move downward synchronously. When the adjusting cylinder 36 descends to the lowest point, that is, when the amount of insulating paper on the transmission path is restored to a sufficient state, the trigger end 371 contacts the detection switch 42 on the lower side of the guide mounting plate 1. The detection switch 42 sends a signal to control the paper feeding mechanism at the front end to restart.

[0030] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
