Description

Technical Field

[0001] This utility model relates to the field of parallel shaft machine technology, specifically to a tension adjustment device for a parallel shaft machine. Background Technology

[0002] The warp beam combining machine is a key piece of equipment in the pre-weaving preparation process of textiles. Its main function is to combine the yarns from multiple warp beams into a single warp beam under constant and uniform tension to meet the warp quality requirements of the weaving process. The uniformity and stability of the yarn tension directly affect the smooth progress of the subsequent weaving process and the quality of the final fabric. Therefore, the warp beam combining machine is usually equipped with a dedicated tension detection and adjustment device to monitor and dynamically adjust the yarn tension in real time.

[0003] In existing technologies, tying machines often use mechanical or pneumatic tension adjustment mechanisms. However, since there is only one point of action, their ability to adjust the tension of the entire yarn is limited. More importantly, during the adjustment process, the oscillation of a single roller can easily generate an unbalanced lateral force on the yarn, causing the yarn to deviate or twist, ultimately affecting the quality of tying.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-5 As shown, this utility model provides a technical solution:

[0026] A tension adjustment device for a parallel shaft machine includes a base 1, with frames 2 fixedly connected to both sides of its top. A crossbeam 20 is fixedly connected between the top sides of the two frames 2. A monitoring mechanism is provided between the upper ends of the two frames 2. The monitoring mechanism includes mounting holes 3 extending through the upper ends of the two frames 2, and tension sensors 4 fixedly fitted inside the mounting holes 3. Tension sensors 4 on the two frames 2 are rotatably connected to a tension roller 5 via bearings. An adjustment mechanism is located between the middle parts of the two frames 2. The adjustment mechanism includes swing arms 13 symmetrically fixedly connected to both ends of a rotating shaft 7, and arc-shaped guide grooves 14 symmetrically opened at both ends of the middle parts of the frames 2. An adjustment roller 15 is fixedly connected to the end of each swing arm 13 away from the rotating shaft 7. Both ends of the adjustment roller 15 extend into the arc-shaped guide grooves 14 and can slide along the arc-shaped guide grooves 14. Guide rollers 19 are rotatably connected between the lower sides of the two frames 2 via bearings. The drive mechanism is located on the outside of the left frame 2. The drive mechanism is connected to the adjustment mechanism. The drive mechanism includes a shaft hole 6 that passes through the middle of the two sides of the frame 2 and a rotating shaft 7 that is rotatably connected between the shaft holes 6 through a bearing. The left end of the rotating shaft 7 passes through the bearing and is fixedly connected to a gear 8. Vertical guide rails 9 are fixedly connected to both ends of the front of the left frame 2. A rack 10 that meshes with the gear 8 is provided at the opposite end of the two guide rails 9. A fixing block 16 is fixedly connected to the middle of the upper end of the left frame 2. An electric push rod 17 is fixedly connected to the top of the fixing block 16. A connecting plate 18 is fixedly connected between the tops of the two racks 10. The output shaft of the electric push rod 17 is fixedly connected to the top of the middle of the connecting plate 18. The drive mechanism also includes a dovetail groove 11 opened on the opposite side of the two guide rails 9 and a dovetail slider 12 fixedly connected to the opposite side of the two racks 10. The dovetail slider 12 and the dovetail groove 11 slide in cooperation.

[0027] In this embodiment, by setting two adjusting rollers 15 that are driven by two rotating shafts 7 and arranged symmetrically, and by using a connecting plate 18 to make the driving mechanism run synchronously, the synchronous reverse swing of the two adjusting rollers 15 is realized. The dual-point adjustment mechanism effectively counteracts the lateral force generated by the single-point adjustment on the yarn, and solves the problem of yarn deviation or twisting caused by unbalanced force in the prior art.

[0028] Furthermore, through the use of a closed-loop control system consisting of a tension sensor 4, an electric push rod 17, a rack 10, and a gear 8, and a linkage adjustment mechanism consisting of two rotating shafts 7, a swing arm 13, and an arc-shaped guide groove 14, real-time monitoring and automatic feedback adjustment of the yarn tension 21 are achieved.

[0029] Working principle: When the yarn 21 passes through the guide roller 19, tension roller 5 and adjusting roller 15 in sequence, the tension sensor 4 fixed in the mounting hole 3 will monitor the tension of the yarn 21 in real time and output a signal. If the tension deviates from the set value, the control system will activate the electric push rod 17. The output shaft of the electric push rod 17 pushes or pulls the connecting plate 18. The connecting plate 18 drives the two racks 10 to move vertically synchronously under the sliding cooperation of the dovetail groove 11 and the dovetail slider 12 of the guide rail 9. The racks 10 drive the gears 8 meshing with them to rotate forward or backward, thereby driving the gears fixedly connected to the gears 8 to rotate. The rotating shaft 7 rotates, causing the swing arms 13, which are symmetrically fixed at both ends, to swing synchronously. This causes the two adjusting rollers 15, which are fixedly connected to the ends of the swing arms 13, to rotate accordingly. Since the two ends of the adjusting rollers 15 extend and slide in the arc-shaped guide grooves 14 of the frame 2, their swing trajectory is constrained by the arc-shaped guide grooves 14, thereby changing the wrap angle of the yarn 21 on the adjusting rollers 15, realizing the automatic adjustment of the tension of the yarn 21 until the tension value fed back by the tension sensor 4 returns to the set range, forming a closed-loop control, and finally ensuring that the tension of the yarn 21 remains stable during the spindle winding process.

[0030] In the specific implementation of this technical solution, the control system between the electric actuator 17 and the tension sensor 4 can be configured with conventional PLCs (Programmable Logic Controllers), microprocessors, or dedicated tension controllers. Although such control systems are not described in detail in this technical solution, they are components that can be conventionally selected by those skilled in the art based on actual tension closed-loop control requirements. Their signal acquisition, logic operations, and instruction output follow well-known technologies in the field and do not affect the implementation of the core innovation of this solution. In practical applications, the control system is mainly used to receive sensor signals and drive the electric actuator to perform actions, but its specific type and connection method can be adjusted according to production requirements, all of which fall within the reasonable extension scope of this technical solution.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
