Description

Technical Field

[0001] The utility model relates to the technical field of yarn quality detection, in particular to a tensile force detection device for textile yarns. Background Technique

[0002] Yarn is the basic element of textile. It is composed of many short fibers or filaments arranged in an approximately parallel state and twisted axially to form an elongated object with a certain strength and linear density. It plays a dual role as a foundation and a bridge in the process of clothing production and processing.

[0003] A tensile force detection device for textile yarns is proposed in the utility model patent with the authorized announcement number of CN220063660U, which relates to the technical field of yarn quality detection. It includes an installation frame. Two wire tying blocks for fixing the yarn ends are symmetrically arranged in the installation frame. One of the wire tying blocks is fixedly connected to the inside of the installation frame, and the other wire tying block is slidably connected to the inner wall of the installation frame. A number of stepped surfaces are arranged in a staggered manner on the opposite surfaces of the two wire tying blocks, and wire grooves and clamping grooves for placing the yarn are opened at the positions corresponding to the stepped surfaces on the top surfaces of the wire tying blocks. A pressing plate is arranged on the wire tying block. A sliding block is slidably connected to the position corresponding to the clamping groove on the bottom surface of the pressing plate. A winding column for winding and fixing the yarn is rotatably connected to the bottom surface of the sliding block, which is convenient for making the rack slide along the surface of the pressing plate by rotating the bolt under the limiting action of the guide rod.

[0004] In the above patent, during the tensile test, the yarn is tied with a wire tying block. In actual tests, due to stress concentration at the corners during tying, the fracture points in the tensile test are often the tying points, resulting in a large error in the test results of the yarn in the tensile test. To solve the above problems, we propose a tensile force detection device for textile yarns. Content of the Utility Model

[0008] Preferably, a lateral support platform is fixedly installed on the side of the frame, and a controller is fixedly installed on the lateral support platform.

[0009] Preferably, a plurality of tensile force sensors are fixedly connected between the connecting plate and the upper mounting plate, and the tensile force sensors are electrically connected to the controller.

[0012] Preferably, the outside of the contact ring does not contact the threaded area, and a hexagonal inner groove is opened on the outer circumference of the outside of the contact ring.

[0013] Preferably, the inner diameter of the sliding cylinder is adapted to the diameter of the sliding rod, and the sliding cylinder is made of rubber.

[0014] Compared with the related art, a tensile force detection device for textile yarns proposed by the present utility model has the following beneficial effects:

[0015] In the present utility model, for a tensile force detection device for textile yarns, through the provided yarn fixing mechanism, in the yarn fixing mechanism, the yarn is clamped by the yarn clamping groove arranged inside the sliding cylinder. Additionally, several convex strips are arranged in the yarn clamping groove to increase the clamping friction force of the inner part of the clamping groove on the yarn. At the same time, the whole sliding cylinder is made of rubber material. By rotating the screwing ring, the screwing ring, through the screwing transmission effect with the threaded area on the sliding rod, pushes the abutting ring to move inward. Then, the sliding cylinder located between the fixed ring and the abutting ring is gradually squeezed, and the yarn clamping groove inside the sliding cylinder gradually contracts and provides a certain clamping force to the yarn clamped inside it, so that the end of the yarn is clamped and fixed in the yarn clamping groove inside the sliding cylinder. This fixing method for the end of the yarn reduces the stress concentration phenomenon at the fixing part compared with the binding method, making the fixing part no longer the easily broken area in the whole tensile force test link, further making the tensile force detection result of the yarn more accurate and improving the practicability.

Detailed Embodiment

[0021] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0022] Refer to Figures 1-4 and, please refer to Figures 1-4 , wherein, Figure 1 is a schematic perspective view of a tensile force detection device for textile yarns proposed by the present utility model Figure 1; Figure 2 Partial three-dimensional structure diagram of a yarn tensile testing device proposed by the present utility model; Figure 3 Partial three-dimensional sectional structure diagram of a yarn tensile testing device proposed by the present utility model; Figure 4 Magnified three-dimensional structure diagram of the sliding cylinder. A yarn tensile testing device for textile includes: a bottom plate 1, on which a frame 2 is fixedly installed, on which an electric telescopic rod 5 is fixedly installed, the output end of the electric telescopic rod 5 passes through to the bottom side of the frame 2 and a connecting plate 6 is fixedly installed at the bottom of the electric telescopic rod 5, a upper mounting plate 7 is arranged on the lower side of the connecting plate 6, a lower mounting plate 8 is fixedly installed on the upper side of the bottom plate 1, and yarn fixing mechanisms 9 are installed on both the upper mounting plate 7 and the lower mounting plate 8.

[0023] In this mode, the yarn fixing mechanism 9 includes a sliding rod 93, side supports 91 are symmetrically screwed and installed on both the lower side of the upper mounting plate 7 and the upper side of the lower mounting plate 8, the sliding rod 93 is inserted between the two side supports 91, a fixing ring 96 is fixedly installed on the left side of the sliding rod 93, a threaded area 97 is arranged on the right side of the sliding rod 93, a screwed ring 98 is screwed and sleeved on the outside of the threaded area 97, a contact ring 99 is fixedly connected to the side of the screwed ring 98, and a number of sliding cylinders 911 are arranged between the contact ring 99 and the fixing ring 96. A yarn card slot 912 is opened inside the sliding cylinder 911, and convex strips 913 are evenly arranged inside the yarn card slot 912.

[0024] Through the above arrangement, when fixing the yarn, both ends of the yarn are respectively wound around the inside of the yarn card slots 912 on the upper mounting plate 7 and the lower mounting plate 8. Subsequently, the screwed ring 98 is rotated, and the screwing action between the screwed ring 98 and the threaded area 97 on the sliding rod 93 pushes the contact ring 99 to move inward. Then, the sliding cylinders 911 located between the fixing ring 96 and the contact ring 99 are gradually squeezed, so that the yarn card slots 912 inside the sliding cylinders 911 gradually contract and provide a certain clamping force to the yarn clamped inside it, so that the end of the yarn is clamped and fixed inside the sliding cylinder 911.

[0025] In this mode, a lateral support platform 3 is fixedly installed on the side of the frame 2, a controller 4 is fixedly installed on the lateral support platform 3, a number of tensile sensors 11 are fixedly connected between the connecting plate 6 and the upper mounting plate 7, and the tensile sensors 11 are electrically connected to the controller 4.

[0026] Through the above arrangement, when the electric telescopic rod 5 is started to rise, the connecting plate 6 drives the upper mounting plate 7 to move upward through the force transmission of the tensile sensors 11. Then, the total tensile force sensed by the number of tensile sensors 11 is the total mass of the upper mounting plate 7 and the lower yarn fixing mechanism 9 plus the tensile force of the yarn. The total mass of the upper mounting plate 7 and the lower yarn fixing mechanism 9 is a fixed value. When the yarn breaks, the controller 4 can calculate the average tensile resistance of each yarn through the internal program.

[0027] In this embodiment, two guide rods 10 are symmetrically fixedly installed on the upper side of the connecting plate 6 , and the guide rods 10 slide through to the upper side of the frame 2 .

[0028] Through the above-mentioned arrangement, the guide rod 10 provides a guiding function for the connecting plate 6 when it moves, so that the connecting plate 6 can rise or fall more stably when driven by the electric telescopic rod 5 .

[0029] In this embodiment, a slot 92 is provided inside the side support 91 , a slide bar 93 is inserted inside the slot 92 , a limit key 94 is fixedly installed on the side of the slot 92 , and a limit groove 95 is provided at the end of the slide bar 93 corresponding to the limit key 94 .

[0030] By the above-mentioned arrangement, the limit key 94 and the limit slot 95 are arranged so that the rotational freedom of the slide bar 93 is limited when the slide bar 93 is inserted into the inner side of the slot 92 on the inner side of the side support 91 .

[0031] In this embodiment, the outer side of the abutment ring 99 does not contact the threaded area 97 , and a hexagonal inner groove 910 is provided around the outer circumference of the abutment ring 99 .

[0032] By the above-mentioned arrangement, the hexagonal inner groove 910 is arranged so that when the abutment ring 99 is rotated, a hexagonal wrench can be used to turn it, so that the abutment ring 99 can be driven to move more labor-savingly.

[0033] In this embodiment, the inner diameter of the slide cylinder 911 matches the diameter of the slide rod 93 , and the slide cylinder 911 is made of rubber.

[0034] Through the above-mentioned arrangement, the slide cylinder 911 is made of rubber material, so that when the inner side of the slide cylinder 911 clamps and fixes the yarn, no clamping damage is caused to the yarn, thereby reducing the stress concentration phenomenon during stretching.

[0035] The working principle of the tension detection device for textile yarn provided by the utility model is as follows:

[0036] When in use, the two ends of the yarn are respectively wound around the inner sides of the yarn clamping grooves 912 on the upper mounting plate 7 and the lower mounting plate 8, and then the hexagonal wrench is used to act on the inner side of the hexagonal inner groove 910 to drive the abutment ring 99 to rotate, thereby synchronously driving the threaded connection ring 98 to be threadedly connected to the threaded area 97 on the slide rod 93, thereby driving the abutment ring 99 to move toward the fixed ring 96, and then the slide cylinder located between the fixed ring 96 and the abutment ring 99 is gradually squeezed, and the yarn clamping groove 912 on the inner side of the slide cylinder 911 gradually shrinks and clamps the yarn clamping groove 912 therein. The yarn on the side provides a certain clamping force, so that the end of the yarn is clamped and fixed in the yarn clamping groove 912 on the inner side of the slide 911, and the two ends of the yarn are fixed and clamped on the inner side of the upper and lower slides 911 respectively. At this point, the fixing of the yarn is completed. Subsequently, the electric telescopic rod 5 is started to rise, and the connecting plate 6 drives the upper mounting plate 7 to move upward through the tension sensor 11. When the yarn breaks, the controller 4 can calculate the average tensile strength of each yarn through internal degree calculation based on the tension value fed back by the tension sensor 11.

[0037] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
