Description

Technical Field

[0001] This utility model relates to the field of single yarn strength testing machine technology, specifically a single yarn strength testing machine for fabric preparation with improved precision. Background Technology

[0002] A single yarn strength tester is a professional instrument used to test the mechanical properties of a single yarn or fiber. It is mainly used to determine key indicators such as the breaking strength and elongation at break of yarn, and is widely used in the testing of textiles, chemical fibers, and materials.

[0003] Chinese patent CN119470048A discloses an automated single yarn strength tester and testing method, relating to the field of textile testing equipment technology. The method includes: a single yarn strength tester for determining the breaking strength, elongation at break, and tensile strength of single yarns and pure or blended yarns; and a translation mechanism for translating multiple distributed yarns to different positions and performing continuous, high-efficiency testing. This automated single yarn strength tester uses a tension spring to pull a connecting piece, which in turn drives a fastening piece and a limiting block to limit the installation of a limiting groove on a rubber pad. This allows for quick replacement of the rubber pad after wear, ensuring the stability of the yarn clamping and guaranteeing testing accuracy. Replacing the rubber pad restores good friction on the clamping surface, ensuring the single yarn is tightly fixed in the clamping mechanism. This prevents the single yarn from moving during tensile testing due to unstable clamping, ensuring smooth testing and accurate results.

[0004] Traditional single-yarn strength testing machines in the present technology have problems such as large fluctuations in yarn tension and uneven relaxation during the testing process. In addition, because they require frequent manual operation of the fixture for positioning and yarn replacement, the overall testing efficiency is low and it is difficult to meet the requirements of efficient and stable testing. Utility Model Content

[0005] The purpose of this invention is to provide a single yarn strength tester for fabric preparation with improved precision, in order to solve the problems of large yarn tension fluctuations and uneven relaxation in the above-mentioned background technology, as well as the problem of frequent manual operation of the clamps for positioning and yarn replacement.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a single yarn strength tester for fabric preparation with improved accuracy, comprising a single yarn strength tester body placed vertically on the ground, an adjustment groove provided on the front side of the single yarn strength tester body, two horizontally and symmetrically distributed adjustment screws rotatably connected inside the adjustment groove; an adjustment frame slidably connected inside the adjustment groove, an adjustment rail slidably connected inside the adjustment frame, and the sliding direction of the adjustment frame and the sliding direction of the adjustment rail are perpendicular to each other; two symmetrically distributed detection sliders slidably connected inside the adjustment rail, a mounting block fixedly connected to one side of each detection slider, and two symmetrically distributed fixed shafts fixedly connected inside the mounting block; a swing arm rotatably connected to the outside of each fixed shaft, and both swing arms fixedly connected to connecting rods, with the ends of the two connecting rods away from the swing arms located on the same axis.

[0007] Preferably, the mounting block has a reserved hole in the middle, and the reserved hole and the end of the connecting rod are aligned with each other. The end of the swing arm away from the connecting rod is fixedly connected to a clamping block, and the two clamping blocks are symmetrically distributed to form a clamp.

[0008] Preferably, a fixed rod is fixedly connected to the inner side of the adjustment frame, and the fixed rod passes through the interior of the reserved hole. The other end of the swing arm is rotatably connected to the outer side of the fixed rod. A push rod is fixedly connected to the middle of the inner side of the adjustment frame, and the telescopic end of the push rod is connected to the adjustment rail.

[0009] Preferably, a reverse lead screw is rotatably connected inside the adjusting rail, and a motor is fixedly connected to the top of the adjusting rail, with the motor output end connected to the reverse lead screw.

[0010] Preferably, the top rear side of the single yarn strength machine body is fixedly connected with equidistantly distributed yarn guides, and the top of the single yarn strength machine body is fixedly connected with equidistantly distributed damping wheels, and each yarn guide and each damping wheel are aligned with each other.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This single yarn strength tester for fabric preparation with improved accuracy achieves precise positioning of the clamping blocks in a two-dimensional plane by adjusting the lead screw to drive the adjustment frame to move horizontally and the reverse lead screw to drive the detection slider to move symmetrically in the opposite direction. This meets the needs of different yarn spacing and stretching paths. The connecting rod drives the swing arm to rotate around the fixed axis, so that all clamping blocks automatically and synchronously open and retract into the adjustment frame as a whole. The clamps can be quickly moved away from the test area without manual intervention, leaving sufficient space for the operator to quickly remove old yarns and place new yarns, greatly shortening the test interval time and improving the efficiency of continuous batch testing.

[0022] 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.

[0023] Example 1: Please refer to Figure 1 - Figure 6This utility model provides the following technical solution: A single yarn strength tester for fabric preparation with improved accuracy, comprising a single yarn strength tester body 1 placed vertically on the ground, an adjustment groove 2 provided on the front side of the single yarn strength tester body 1, two horizontally and symmetrically distributed adjustment screws 3 rotatably connected inside the adjustment groove 2; an adjustment frame 4 is horizontally slidably connected inside the adjustment groove 2, an adjustment rail 5 is slidably connected inside the adjustment frame 4, and the sliding direction of the adjustment frame 4 and the sliding direction of the adjustment rail 5 are perpendicular to each other; two symmetrically distributed detection sliders 6 are slidably connected inside the adjustment rail 5, and a mounting block 7 is fixedly connected to one side of the detection slider 6, and the mounting block 7 is fixedly connected inside... There are two symmetrically distributed fixed shafts 9. A swing arm 10 is rotatably connected to the outer side of each fixed shaft 9. Each swing arm 10 is fixedly connected to a connecting rod 11, and the ends of the two connecting rods 11 furthest from the swing arm 10 are located on the same axis. A pre-drilled hole 8 is provided in the middle of the mounting block 7, and the pre-drilled hole 8 and the end of the connecting rod 11 are aligned with each other. A clamping block 12 is fixedly connected to the end of the swing arm 10 furthest from the connecting rod 11, and the two clamping blocks 12 are symmetrically distributed to form a clamp. A fixed rod 13 is fixedly connected to the inner side of the adjusting frame 4, and the fixed rod 13 passes through the pre-drilled hole 8. The other end of the swing arm 10 is rotatably connected to the outer side of the fixed rod 13. A [missing information - likely a continuation of the previous sentence] is fixedly connected to the middle of the inner side of the adjusting frame 4. A push rod 14 is provided, with its telescopic end connected to the adjusting rail 5. A reverse lead screw 15 is rotatably connected inside the adjusting rail 5. A motor 16 is fixedly connected to the top of the adjusting rail 5, and its output end is connected to the reverse lead screw 15. Equally spaced yarn guide frames 17 are fixedly connected to the rear top of the single yarn strength machine body 1. Equally spaced damping wheels 18 are fixedly connected to the top of the single yarn strength machine body 1, with each yarn guide frame 17 and each damping wheel 18 aligned with each other. Equally spaced bogies 19 are fixedly connected to the front top and the top of the front side of the single yarn strength machine body 1, with each bogie 19 and each damping wheel 18 aligned with each other. The two sets of bogies 19 are vertically distributed; the front side of the single yarn strength machine body 1 is rotatably connected with equidistant support wheels 20, and each support wheel 20 and each bogie 19 are aligned with each other, and the support wheels 20 are located at the bottom of the adjustment groove 2. The front bottom of the single yarn strength machine body 1 is fixedly connected with equidistant hollow rods 21, and each hollow rod 21 and each support wheel 20 are aligned with each other. A slide rod 22 is slidably connected inside the hollow rod 21, and the slide rod 22 extends to the outside of the hollow rod 21. A spring is provided inside the hollow rod 21 to drive the slide rod 22 to move toward the hollow rod 21, so that the end of the slide rod 22 and the end of the hollow rod 21 form a clamp.

[0024] After the single yarn strength tester body 1 is placed vertically on the ground, the yarn is introduced from the outside and passes through the yarn guide frame 17 on the rear side of the top of the single yarn strength tester body 1. The yarn guide frame 17 guides the yarn through the damping wheels 18 fixed at equal intervals on the top of the single yarn strength tester body 1. The damping wheels 18 apply frictional resistance to the yarn, effectively reducing vibration and slack during the yarn's operation, ensuring that the yarn maintains a uniform and stable tension state before testing. Subsequently, the yarn changes direction by passing through the front side of the top of the single yarn strength tester body 1 and the bogie 19 on the top of the front side; each set of bogies 19 is associated with a corresponding damping wheel 18. Precise alignment, through the vertical distribution of two sets of bogies 19, ensures a smooth turning of the yarn path, effectively avoiding twisting or knotting of the yarn during the guiding process. The yarn eventually extends downward to the support wheel 20 on the front side of the single yarn strength machine body 1. Each support wheel 20 is aligned and rotated with the corresponding bogie 19, playing the role of supporting the yarn and guiding the yarn to descend precisely vertically. The yarn guide frame 17 ensures parallel yarn introduction, the damping wheel 18 controls the tension, and the bogie 19 achieves smooth multi-directional turning. Finally, guided by the support wheel 20, the yarn is evenly distributed on the front side of the adjustment groove 2.

[0025] When conducting a single yarn strength test, the test section of the yarn is placed between two symmetrically distributed clamping blocks 12. The telescopic end of the push rod 14 pushes the adjusting rail 5, causing it to slide in the set direction inside the adjusting frame 4. At this time, the fixed rod 13, which is fixed inside the adjusting frame 4, moves inside the reserved hole 8 of the mounting block 7. Since one end of the connecting rod 11 is fixedly connected to the swing arm 10, and the end of the connecting rod 11 away from the swing arm 10 is rotatably connected to the outside of the fixed rod 13, the movement of the fixed rod 13 in the reserved hole 8 drives the two swing arms 10 to rotate synchronously around their respective fixed axes 9 through the connecting rod 11. The rotational movement of the swing arms 10 causes the clamping blocks 12 fixedly connected to them to close, thereby achieving reliable clamping of the yarn located between the two clamping blocks 12.

[0026] After the yarn ends are stably clamped by the clamps formed by the corresponding clamping blocks 12, a tensile test can be performed. By activating the two horizontally and symmetrically distributed adjusting screws 3 located inside the adjusting groove 2, the adjusting frame 4 is driven to move horizontally inside the adjusting groove 2. The adjusting rail 5 is slidably connected inside the adjusting frame 4, and its sliding direction is perpendicular to the sliding direction of the adjusting frame 4. At the same time, the motor 16 located at the top of the adjusting rail 5 is started, driving the reverse screw 15 to rotate. The rotation of the reverse screw 15 drives the two symmetrically distributed detection sliders 6 on it to move synchronously in the opposite direction inside the adjusting rail 5. The horizontal movement of the adjusting frame 4 and the symmetrical reverse movement of the detection sliders 6 work together to control the position of the clamping blocks 12, so that the two sets of clamps holding the yarn ends slowly move away along the set path. The moving away movement of the clamps applies tensile tension to the yarn, thereby realizing the tensile test of the yarn.

[0027] When the tensile test of the current yarn is completed and the next yarn is replaced, the telescopic end of the push rod 14 retracts, driving the adjustment rail 5 to slide towards the inside of the adjustment frame 4. At this time, the fixed rod 13 slides in the opposite direction inside the reserved hole 8. This movement is also transmitted through the connecting rod 11, driving the two swing arms 10 to rotate in the opposite direction around the fixed axis 9. The reverse rotation of the swing arms 10 causes the clamping block 12 fixed to it to open, so that the two clamping blocks 12 move away from each other. At the same time, the movement of the adjustment rail 5 towards the inside of the adjustment frame 4 causes the entire clamping mechanism to move towards the inside of the adjustment frame 4 until the clamp is fully opened and the overall position does not interfere with the area of ​​the yarn to be tested. This reset state makes room for the clamping mechanism, so that the operator can easily remove the tested yarn and place the next yarn to be tested for subsequent testing.
