Abstract
Description
Technical Field
[0001] This utility model relates to the field of continuous feeding technology, and in particular to a tension-controlled continuous feeding mechanism for steel belts. Background Technology
[0002] Continuous feeding refers to the continuous delivery of raw materials, supplies, or components into the work area or processing equipment in industrial production, automated production lines, or machinery to ensure the continuity and efficiency of the production process. This process is usually automated, which can improve production efficiency, reduce human intervention, and ensure the stability of the production process.
[0003] A thin steel strip constant tension adaptive feeder (publication number: CN109484889B) includes a steering frame, an equipment frame, a three-dimensional adjustment unit for steel strip steering control, a steel strip tray rotation device and its servo system and control unit, a steering wheel mechanism, a speed adaptive unit, and a steel strip guiding and leveling unit. The three-dimensional adjustment unit allows the steel strip to smoothly transition in multiple directions (up / down, left / right, tilting, and rotation) to the adaptive unit's guide rollers. Constant tension speed adaptive feeding of the steel strip is achieved through the three guide rollers of the speed adaptive unit, speed feedback, and tension counterweights. This invention uses multi-reel steel strip coil feeding, combining speed adaptive control with tension control to achieve constant tension adaptive feeding. It solves problems such as unstable feeding speed and strip edge wrinkling in corrugated pipe forming equipment, cable welding pipe equipment, and thin-part punching equipment, and has advantages such as high feeding accuracy, stable speed, adaptability, and constant tension.
[0004] The components such as the steering frame and equipment frame in the above patent work together to solve problems such as unstable feeding speed and strip edge wrinkling in corrugated pipe forming equipment, cable welding pipe equipment, and thin-part punching equipment. However, they cannot achieve better adjustment of the tension of the steel strip. Therefore, we propose a tension-controlled continuous feeding mechanism for steel strip. Utility Model Content
[0005] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that continuous feeding cannot better adjust the tension of the steel strip. To this end, we propose a tension-controlled continuous feeding mechanism for steel strip.
[0006] To achieve the above objectives, this application adopts the following technical solution: a tension-controlled continuous steel belt feeding mechanism, comprising: a base, a drive motor fixedly connected to the side of the base, a roller fixedly connected to the output shaft of the drive motor, a steel belt being sleeved on the circumferential surface of the roller and the output shaft of the drive motor, and a tension adjustment device being provided on the inner side of the base.
[0007] The tension adjustment device includes a fixed plate, whose side is fixedly connected to the inner side of the base. A motor is fixedly connected to the side of the fixed plate, and a threaded rod is fixedly connected to the output shaft of the motor. A threaded sleeve is threadedly connected to the circumferential surface of the threaded rod. A sliding groove is formed on the inner side of the base, and a sliding block is slidably connected to the inner side of the sliding groove. One end of the sliding block is rotatably connected to a rotating shaft, and one end of the rotating shaft is rotatably connected to one end of a roller. A push rod is fixedly connected to the circumferential surface of the threaded sleeve, and a locking rod is fixedly connected to one end of the push rod. A limit rod is fixedly connected to the side of the fixed plate. The entire tension adjustment device drives the movement of the threaded rod and threaded sleeve by the motor, precisely adjusting the position of the push rod and locking rod, thereby affecting the movement of the sliding block and rotating shaft, and thus adjusting the contact state between the roller and the steel belt, ultimately controlling the tension of the steel belt. The limit rod ensures the range of motion and adjustment safety of the device, preventing system damage.
[0008] Preferably, the circumferential surface of the threaded sleeve is slidably connected to the circumferential surface of the limiting rod, and a spring is fixedly connected to the top inner side of the locking rod. The sliding connection between the threaded sleeve and the limiting rod, the design of the locking rod, and the application of the spring work together to ensure the flexibility and stability of the device during movement, while also providing the necessary elastic force through the spring to adjust and lock the position.
[0009] Preferably, one end of the spring is fixedly connected to an arc-shaped locking block, and the side of the sliding block is located on the displacement trajectory of the locking rod. The main function of this structure is to achieve precise guidance of components, limit the range of motion, or adjust the movement of the mechanical system through the force of the spring and the cooperation between the arc-shaped locking block, the sliding block, and the locking rod.
[0010] Preferably, there are two sliding grooves and sliding blocks, which are symmetrical about the longitudinal axis of the base. By arranging the two sliding grooves and sliding blocks in a symmetrical structure about the longitudinal axis of the base, the stability, accuracy, and load-sharing capacity of the system can be effectively improved, ensuring that the mechanical device is more balanced and reliable during operation and extending its service life.
[0011] Preferably, an equipment maintenance device is provided on the inner side of the base. The device includes an oil tank, which is fixedly connected to the inner wall of the base. One end of the oil tank is connected to an oil supply pipe, and the other end of the oil supply pipe is fixedly connected to an air bladder. An oil outlet pipe is connected through the circumference of the air bladder, and one end of the oil outlet pipe is fixedly connected to a nozzle. A strike rod is fixedly connected to the circumference of a threaded sleeve. This equipment maintenance device, through its automatic lubrication function, ensures the continuous and efficient operation of the mechanical equipment and prevents equipment malfunctions due to lack of maintenance.
[0012] Preferably, the circumferential surface of the airbag is located on the displacement trajectory of the impact rod, and the nozzle is located directly above the rotating shaft. The purpose of this design is to lubricate and maintain the rotating shaft through the coordinated work of the airbag, impact rod, and nozzle.
[0013] The technical effects and advantages of this utility model are as follows:
[0014] In this invention, components such as a motor, threaded rod, threaded sleeve, sliding groove, and sliding block work together. When the operator observes that the steel belt is slack, the machine is turned off and the motor is started. The motor drives the threaded rod to rotate, which in turn causes the threaded sleeve to move horizontally under the constraint of the limit rod. The horizontal movement of the threaded sleeve causes the push rod to move horizontally, which in turn causes the locking rod to move horizontally, which in turn causes the spring to move horizontally, which in turn causes the arc-shaped locking block to move horizontally. The arc-shaped locking block locks with the sliding block, and the horizontal movement of the locking rod pushes the sliding block to move horizontally within the sliding groove. The horizontal movement of the sliding block causes the rotating shaft to move horizontally, which in turn causes the roller to move horizontally. The horizontal movement of the roller adjusts the contact state between the roller and the steel belt, ultimately controlling the tension of the steel belt.
[0015] In this invention, components such as a motor, threaded rod, threaded sleeve, oil tank, and air bladder work together. Starting the motor drives the threaded rod to rotate, which in turn causes the threaded sleeve to move horizontally under the constraint of a limiting rod. This horizontal movement of the threaded sleeve drives a striking rod, which in turn compresses the air bladder. The compressed air bladder draws lubricating oil from the oil tank through an oil supply pipe and delivers it to a nozzle through an oil outlet pipe. The lubricating oil is then sprayed onto the rotating shaft for lubrication. This achieves automatic lubrication, ensuring the continuous and efficient operation of the machinery and preventing malfunctions due to lack of maintenance. Attached Figure Description

[0024] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0025] Reference Figures 1-6 As shown, this utility model provides a technical solution: a tension-controlled continuous feeding mechanism for steel belts, comprising: a base 1, a drive motor 2 fixedly connected to the side of the base 1, a roller 3 fixedly connected to the output shaft of the drive motor 2, a steel belt 4 sleeved on the circumferential surface of the roller 3 and the output shaft of the drive motor 2, and a tension adjustment device 5 provided on the inner side of the base 1.
[0026] The tension adjustment device 5 includes a fixed plate 51, the side of which is fixedly connected to the inner side of the base 1. A motor 52 is fixedly connected to the side of the fixed plate 51, and a threaded rod 53 is fixedly connected to the output shaft of the motor 52. A threaded sleeve 54 is threadedly connected to the circumferential surface of the threaded rod 53. A sliding groove 55 is provided on the inner side of the base 1, and a sliding block 56 is slidably connected to the inner side of the sliding groove 55. A rotating shaft 57 is rotatably connected to one end of the sliding block 56, and one end of the rotating shaft 57 is rotatably connected to one end of the roller 3. A push rod 58 is fixedly connected to the circumferential surface of the threaded sleeve 54, and a locking rod 59 is fixedly connected to one end of the push rod 58. A limit rod 510 is fixedly connected to the side of the fixed plate 51. The entire tension adjustment device 5 drives the movement of the threaded rod 53 and the threaded sleeve 54 through the motor 52, precisely adjusting the position of the push rod 58 and the locking rod 59, thereby affecting the movement of the sliding block 56 and the rotating shaft 57, thus adjusting the contact state between the roller 3 and the steel belt 4, and ultimately controlling the tension of the steel belt 4. The limit rod 510 ensures the safety of the device's movement range and adjustment, preventing system damage.
[0027] The circumferential surface of the threaded sleeve 54 is slidably connected to the circumferential surface of the limiting rod 510, and a spring 511 is fixedly connected to the top inner side of the locking rod 59. The sliding connection between the threaded sleeve 54 and the limiting rod 510, the design of the locking rod 59, and the application of the spring 511 work together to ensure the flexibility and stability of the device during movement, while also providing the necessary elastic force through the spring 511 to adjust and lock the position.
[0028] One end of the spring 511 is fixedly connected to an arc-shaped locking block 512, and the side of the sliding block 56 is located on the displacement trajectory of the locking rod 59. The main function of this structure is to achieve precise guidance of components, limit the range of motion, or adjust the movement of the mechanical system through the force of the spring 511 and the cooperation between the arc-shaped locking block 512, the sliding block 56, and the locking rod 59.
[0029] There are two sliding grooves 55 and two sliding blocks 56, which are symmetrical about the longitudinal axis of the base 1. By setting the two sliding grooves 55 and sliding blocks 56 in a symmetrical structure about the longitudinal axis of the base 1, the stability, accuracy and load-sharing capacity of the system can be effectively improved, ensuring that the mechanical device is more balanced and reliable during operation and extending its service life.
[0030] An equipment maintenance device 6 is installed on the inner side of the base 1. The equipment maintenance device 6 includes an oil tank 61, which is fixedly connected to the inner wall of the base 1. An oil supply pipe 62 is connected to one end of the oil tank 61, and an air bladder 63 is fixedly connected to one end of the oil supply pipe 62. An oil outlet pipe 64 is connected to the circumference of the air bladder 63, and a nozzle 65 is fixedly connected to one end of the oil outlet pipe 64. A strike rod 66 is fixedly connected to the circumference of the threaded sleeve 54. The equipment maintenance device 6 ensures the continuous and efficient operation of the mechanical equipment through its automatic lubrication function, preventing equipment failure due to lack of maintenance.
[0031] The circumferential surface of the airbag 63 is located on the displacement trajectory of the impact rod 66, and the nozzle 65 is located directly above the rotating shaft 57. The purpose of this design is to lubricate and maintain the rotating shaft 57 through the coordinated work of the airbag 63, the impact rod 66, and the nozzle 65.
[0032] Working principle: When the operator observes that the steel belt 4 is in a slack state, the machine is turned off and the motor 52 is started. The motor 52 drives the threaded rod 53 to rotate. The rotation of the threaded rod 53 causes the threaded sleeve 54 to move horizontally under the restriction of the limit rod 510. The horizontal movement of the threaded sleeve 54 causes the push rod 58 to move horizontally. The horizontal movement of the push rod 58 causes the locking rod 59 to move horizontally. The horizontal movement of the locking rod 59 causes the spring 511 to move horizontally. The horizontal movement of the spring 511 causes the arc-shaped locking block 512 to move horizontally. The horizontal movement of the arc-shaped locking block 512 locks with the sliding block 56. The horizontal movement of the locking rod 59 pushes the sliding block 56 to move horizontally in the sliding groove 55. The horizontal movement of the sliding block 56 causes the rotating shaft 57 to move horizontally. The horizontal movement of the rotating shaft 57 causes the roller 3 to move horizontally. The horizontal movement of the roller 3 adjusts the contact state between the roller 3 and the steel belt 4.
[0033] The motor 52 is started, which drives the threaded rod 53 to rotate. The rotation of the threaded rod 53 causes the threaded sleeve 54 to move horizontally under the restriction of the limit rod 510. The horizontal movement of the threaded sleeve 54 causes the impact rod 66 to move horizontally and squeeze the air bladder 63. The air bladder 63 is squeezed and draws out the lubricating oil from the oil tank 61 through the oil supply pipe 62. The lubricating oil is then transported to the nozzle 65 through the oil outlet pipe 64. The lubricating oil is sprayed onto the rotating shaft 57 through the nozzle 65 for lubrication.
[0034] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
