Description

Technical Field

[0001] This utility model relates to the field of tape machine equipment technology, and in particular to an adaptive tension adjustment device for tape machines. Background Technology

[0002] A tape machine is a machine used to produce tape or similar tape products. Depending on the properties of the tape substrate and coating liquid, as well as the processing requirements, the structure and configuration of tape machines can vary greatly. Therefore, different tape machines have different requirements for the tension of the tape substrate when stretching.

[0003] However, existing tension adjustment devices for conveyor belts typically require operators to manually adjust the tension of the tension rollers when stretching the conveyor belt substrate. Furthermore, the tension after manual adjustment remains constant and cannot be dynamically adjusted according to the conveying tension of the conveyor belt substrate, making the device inflexible and inconvenient when adjusting the tension. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an adaptive tension adjustment device for tape machines, which solves the problem that existing tape machine tension adjustment devices cannot adaptively and dynamically adjust according to the conveying tension of the tape substrate, resulting in inflexible and inconvenient adjustment.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] An adaptive tension adjustment device for a tape machine is disclosed, wherein a tension roller is slidably sleeved on the tape substrate of the tape machine, and a base plate is included. The base plate is disposed on one side of the tape machine. Vertical plates are respectively installed at the front and rear ends of the top surface of the base plate. Turntables are rotatably installed on the opposite surfaces of the two vertical plates through rotating components. The two ends of the tension roller are eccentrically installed on the corresponding turntables.

[0007] The rotating component consists of a transmission gear and a transmission rack. The transmission gear is rotatably installed inside the vertical plate, and the inner end face of the transmission gear is fixedly connected to the turntable. A through groove is provided on the side wall of the vertical plate, which is located below the transmission gear. The transmission rack passes through the through groove, and the tooth surface of the transmission rack meshes with the transmission gear. The ends of the two transmission racks on the same side are connected by a side frame.

[0008] A fixing block is provided in the middle of the top surface of the base plate, and a sliding rod is slidably passed through the fixing block. The two ends of the sliding rod are respectively connected to the inner side of the corresponding side frame.

[0009] A first telescopic spring and a second telescopic spring are respectively fitted on both sides of the fixed block on the slide rod.

[0010] An adjusting bolt is fitted on the top of the fixed block, and a washer is installed on the threaded end of the adjusting bolt. The washer abuts against the slide rod inside the fixed block.

[0011] A ball bearing is rotatably mounted on the bottom of the gasket, and the ball bearing abuts against the slide bar inside the fixed block.

[0012] A limit plate is fitted on the tension roller, and the tape substrate is fitted on the limit plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: when the tension roller on the turntable is pulled by the tension of the conveyor belt material in the conveyor belt machine, it can drive the tension roller to rotate clockwise or counterclockwise on the vertical plate through the turntable as the conveyor belt material moves, so that the tension roller can adapt to the force it is subjected to, thereby improving the flexibility of the device when adjusting the tension and making it easier for the operator to adjust the tension.

[0014] When the device adjusts the tension, the angle of the tension roller on the turntable as the turntable rotates can be limited by the elastic force generated by the deformation of the side frame, the first telescopic spring, and the second telescopic spring. This limits the adjustment range of the device during the tension adjustment process, thereby reducing the probability of the tension being too tight or too loose during the tension adjustment process and reducing the adverse effects on the subsequent shearing and winding of the tape substrate.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0021] An adaptive tension adjustment device for a conveyor belt machine includes a tension roller 3 slidably mounted on the conveyor belt substrate 15 of the conveyor belt machine 16. The device includes a base plate 13, which is positioned on one side of the conveyor belt machine 16. Vertical plates 1 are mounted at the front and rear ends of the top surface of the base plate 13. Turntables 2 are rotatably mounted on the opposite surfaces of the two vertical plates 1 via rotating components. The tension roller 3 is eccentrically mounted on the corresponding turntables 2. When the tension of the conveyor belt substrate 15 changes, the tension roller 3 is pulled by the traction force, causing the turntables 2 to rotate clockwise or counterclockwise. This design allows the tension roller 3 to adjust its position in real time as the conveyor belt moves, achieving a dynamic adaptive response to tension, avoiding the lag of traditional fixed tension devices, and improving adjustment flexibility.

[0022] The rotating component consists of a transmission gear 14 and a transmission rack 6. The transmission gear 14 is rotatably mounted inside the vertical plate 1. The inner end face of the transmission gear 14 is fixedly connected to the turntable 2. A through groove is provided on the side wall of the vertical plate 1. The through groove is located below the transmission gear 14. The transmission rack 6 passes through the through groove. The tooth surface of the transmission rack 6 meshes with the transmission gear 14. The ends of the two transmission racks 6 on the same side are connected by a side frame 7.

[0023] A fixing block 10 is provided in the middle of the top surface of the base plate 13. A sliding rod 8 is slidably passed through the fixing block 10. The two ends of the sliding rod 8 are respectively connected to the inner side of the corresponding side frame 7.

[0024] A first telescopic spring 9 and a second telescopic spring 12 are respectively fitted on both sides of the fixed block 10 on the slide bar 8. When the turntable 2 rotates, the rack 6 drives the side frame 7 to move, compressing or stretching the corresponding springs to generate elastic force. The elastic deformation of the springs limits the rotation angle of the turntable 2, preventing the tension roller 3 from rotating excessively and causing the tension of the tape substrate 15 to be too tight or too loose, reducing the impact of uncontrolled tension on subsequent cutting and winding processes. Moreover, the first telescopic spring 9 and the second telescopic spring 12 are located on both sides of the fixed block 10, providing bidirectional buffering for the clockwise and counterclockwise rotation of the tension roller 3.

[0025] An adjusting bolt 11 is fitted on the top of the fixed block 10. A washer 18 is installed on the threaded end of the adjusting bolt 11, and the washer 18 abuts against the slide rod 8 inside the fixed block 10. The function of the adjusting bolt 11 is to move the washer 18 towards the top of the slide rod 8, thereby controlling the sliding speed of the slide rod 8 within the fixed block 10 and improving the stability of the device during tension adjustment.

[0026] A ball bearing 17 is rotatably mounted on the bottom of the gasket 18, and the ball bearing 17 abuts against the slide rod 8 inside the fixed block 10. The function of the ball bearing 17 is to reduce the coefficient of friction between the gasket 18 and the slide rod 8, thereby slowing down the wear rate of the gasket 18 and protecting the gasket 18.

[0027] A limiting disc 4 is mounted on the tension roller 3, and the tape substrate 15 is fitted onto the limiting disc 4. The limiting disc 4 provides lateral restraint to the tape substrate 15, preventing the tape from shifting laterally or slipping due to uneven tension during tension adjustment, ensuring stable conveying of the tape along the predetermined path, and improving the accuracy of subsequent processing.

[0028] When using:

[0029] When using this adaptive tension adjustment device for the tape machine, the device can be installed at the bottom of one side of the tape machine 16. This allows the tape substrate 15 output from the tape machine 16 to bypass the tension roller 3 and be re-transmitted back into the take-up roller of the tape machine 16. When the tension on the tape substrate 15 is large, the tension roller 3 will be pulled by the tape substrate 15, causing the tension roller 3 to drive the turntable 2 to rotate clockwise along the vertical plate 1. This drives the transmission gear 14 fixed to the turntable 2 to rotate, causing the transmission gear 14 to mesh with the transmission rack 6. The transmission rack 6 then slides along the vertical plate 1, causing the transmission rack 6 to drive the side frame 7 to move. The side frame 7 then drives the slide rod 8 to move along the fixed... When block 10 slides, the first telescopic spring 9 is stretched and the second telescopic spring 12 is compressed. This causes the two springs to exert a force on the side frames 7 on both sides to counteract the thrust of the transmission gear 14 on the transmission rack 6. This allows the tension roller 3 to remain stable after rotating with the turntable 2 to the appropriate position. If it is necessary to adjust the sliding speed of the slide rod 8, the adjusting bolt 11 can be turned. This changes the fit between the shim 18 at the bottom of the adjusting bolt 11 and the ball bearing 17 at the bottom of the shim 18 and the slide rod 8. This causes the resistance of the slide rod 8 to slide along the fixed block 10 to change accordingly, so that the speed of the tension roller 3 rotating with the turntable 2 can be controlled.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
