Description

Technical Field

[0001] The present invention relates to the technical field of fabric detection, and particularly to a device for detecting the tearing property and tension of a fabric. Background Art

[0002] Fabric is the basic raw material for clothing design and manufacturing. The quality and characteristics of the fabric are the key factors affecting clothing design and application, especially the tearing property and tension of the fabric. Tension is mainly manifested in the stretching and shrinking states of the fabric, and the level of tension performance is also the main factor affecting the tearing property of the fabric. Therefore, the tension detection of the fabric during the fabric production process is an essential item in the fabric detection technology.

[0003] In the invention patent with the patent number: CN2024107695749 and the name: A Tension Application Testing Device for Fabric Production, it realizes the clamping of both ends of the fabric by setting a clamping seam on the rotating cylinder and setting corresponding clamping members. This clamping method is rather difficult to operate when docking both ends of the fabric into the clamping seam respectively, and the volume of the rotating cylinder is too large. It is inconvenient to observe and adjust whether there are wrinkles and unevenness when both ends of the fabric enter the clamping seam. Moreover, the fabric required for this testing method is also large and long, which is likely to cause waste of materials.

[0004] In other existing technologies, generally, the tension test is completed by clamping both ends of the fabric and stretching it. This testing method cannot ensure the uniform force on the fabric and the smoothness of the fabric during the stretching process.

[0005] Therefore, the present invention provides a device for detecting the tearing property and tension of a fabric, which is convenient for clamping both ends of the fabric and can also ensure the uniform force and smoothness of the fabric during the test. Summary of the Invention

[0009] As a preferred technical solution, the rod brackets are arranged along the length direction of the guide rod group.

One of the connecting plates is connected to the connecting frame through a push rod. Matching pressing strips and pressing grooves are respectively provided on the two clamping plates. And one of the clamping plates is an electromagnet that can attract and hold the other clamping plate.

[0011] As a preferred technical solution, the clamping and feeding mechanism includes a transfer seat, a support frame, and a clamping and flipping assembly. The transfer seat is slidably installed on the support frame. The support frame is fixedly installed on the workbench. The transfer seat is in transmission connection with the driving mechanism in the workbench through a connecting rod group. The clamping and flipping assembly is arranged on the transfer seat. One end of the connecting rod group is hinged to the transfer seat and the other end is rotatably connected to the driving mechanism.

[0012] As a preferred technical solution, the clamping and flipping assembly includes a clamping hand, a flipping rod, a flipping seat, and a cylinder. The cylinder and the flipping seat are both installed on the transfer seat. The clamping hand is fixedly installed on the flipping rod. The flipping rod is rotatably installed on the flipping seat.

[0015] Beneficial Effects: To address the technical issues of ensuring uniform force applied to each section of the fabric during fabric tear and tension testing, the present invention uses a clamping mechanism to transfer one end of the fabric to be tested from one end of a tensioning assembly to the other, clamping the ends of the fabric using clamping assemblies at both ends of the tensioning assembly. A pre-tensioning mechanism brings the tensioning rods of the tensioning assembly into close contact with the fabric, causing the fabric to form a wavy shape between the tensioning rods, thereby pre-tensioning the fabric. A translation mechanism then drives the tensioning rods and clamping assemblies to move toward each other to stretch the fabric, and sensors on each tensioning rod and clamping assembly detect and collect fabric tension data. The present invention uses multiple tensioning rods to divide the fabric into multiple sections, testing the tension of each section during the tensioning process. This ensures uniform force applied to each section and effectively ensures fabric smoothness using the pre-tensioning mechanism, further facilitating accurate and reliable fabric tear and tension testing.

Detailed implementation manners

[0017] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.

[0018] As Figure 1 shown, the following preferred technical solutions are provided: A device for detecting the tearing property and tension of a cloth, comprising: a clamping assembly 1 for clamping both ends of the cloth and a tensioning assembly 2 for tensioning the cloth. Below the tensioning assembly 2, there are provided a cloth feeding mechanism 3 for passing the cloth through the tensioning assembly 2 and a pre-tightening mechanism 4 for assisting in tensioning the cloth. The tensioning assembly 2 and the cloth feeding mechanism 3 are both installed on a workbench 5. The clamping assembly 1 is installed at both ends of the tensioning assembly 2. The cloth feeding mechanism 3 and the pre-tightening mechanism 4 are both driven by a driving mechanism installed in the workbench 5. The tensioning assembly 2 is installed on the top of the workbench 5. The tensioning assembly 2 includes a plurality of tensioning rods 21 for tensioning the cloth and a translation mechanism 22 for driving each tensioning rod 21 to move horizontally to both sides.

[0019] Specifically, to solve the technical problems of the transportation of the fabric before clamping at both ends during the fabric tearing and tension detection process, whether the forces on each section of the fabric are uniform during the fabric tension detection, and whether the overall fabric is smooth under the tensioned state, the present invention transfers one end of the fabric to be detected from one end of the tensioning assembly 2 to the other end through the pinch feeding mechanism 3, and clamps both ends of the fabric through the clamping assemblies 1 at both ends of the tensioning assembly 2. The pre-tensioning mechanism 4 makes each tensioning rod 21 of the tensioning assembly 2 closely adhere to the fabric and enables the fabric to present a wavy state between each tensioning rod 21, completing the pre-tensioning of the fabric. Subsequently, the translation mechanism 22 drives each tensioning rod 21 and the clamping assembly 1 to move and stretch the fabric to both sides, and the tension data of the fabric is detected and collected through the sensors on each tensioning rod 21 and the clamping assembly 1. The present invention uses multiple tensioning rods 21 to divide the fabric into multiple sections, detects the tension of each tensioning section during the tensioning process, and also ensures the uniform force on each section of the fabric. The pre-tensioning mechanism 4 effectively guarantees the smoothness of the fabric, which is more conducive to the accuracy and authenticity of the fabric tearing and tension detection.

[0020] As Figures 2 to 7 shown, the following preferred technical solutions are provided: The translation mechanism 22 includes a guide rod group 221, an equidistant transmission rod 222, and a driving wheel group 223. The guide rod group 221, the equidistant transmission rod 222, and the driving wheel group 223 are all fixedly installed above the workbench 5 through a mounting frame 224. The guide rod group 221 is located below the equidistant transmission rod 222 and is slidably connected thereto. The driving wheel group 223 is in transmission connection with the equidistant transmission rod 222. Each tensioning rod 21 is slidably connected to the guide rod group 221 through a rod holder 225. The rod holder 225 is slidably connected to the equidistant transmission rod 222. Equidistant spiral grooves 226 are symmetrically arranged on the equidistant transmission rod 222, and the spiral directions of the equidistant spiral grooves 226 at both ends of the equidistant transmission rod 222 are opposite. Each rod holder 225 is slidably connected to the corresponding equidistant spiral groove 226 through a connector 227.

[0021] Each rod holder 225 is arranged along the length direction of the guide rod group 221. The rod holders 225 at both ends are each fixedly connected to a clamping assembly 1, and only the rod holders 225 in odd positions or only the rod holders 225 in even positions are slidably connected to the corresponding tensioning rods 21 through sliding grooves 228. The sliding grooves 228 are opened on the corresponding rod holders 225. A sliding guide rod 229 is provided at the upper end of the tensioning rod 21 slidably connected to the rod holder 225, and the sliding guide rod 229 is connected to the corresponding rod holder 225 through a spring 220.

[0022] Specifically, to solve the technical problem of applying a stable tension to the fabric and ensuring uniform stress on the tension of each section of the fabric, the present invention drives the equally spaced transmission rod 222 to rotate through the driving wheel set 223. The equally spaced spiral grooves 226 on the equally spaced transmission rod 222 cooperate with the connectors 227 on each rod holder 225. After the fabric is clamped by the clamping assemblies 1 at both ends, when the rod holders 225 move towards each other along the two ends of the guiding rod set 221, the fabric is stretched between each tension rod 21, and sensors at corresponding positions on each tension rod 21 are used to detect the tension of the fabric.

[0023] During the entire detection process, the positional states of the rod holder 225 and the tension rod 21 are divided into three types. The first state is the fabric clamping and feeding state, which is also the initial state: First, during the fabric clamping and feeding process, the fabric is clamped from one clamping assembly 1 to the other clamping assembly 1 at the other end through the clamping and feeding mechanism 3. At this time, the tension rods 21 slidably connected to the rod holder 225 form an interleaved state with other tension rods 21 under the action of the spring 220, and the clamping and feeding mechanism 3 drives the fabric to move in the channels between the interleaved tension rods 21. The second state is the pre-tightening state: After the fabric clamping and feeding is completed, the pre-tightening mechanism 4 starts to abut against the lower end of the corresponding slidable tension rod 21, pressing the tension rod 21 to the column where the other non-slidable tension rods 21 are located. At this time, the movable tension rod 21 closely adheres to the fabric, so that the fabric forms a wavy pre-tightening state between each tension rod 21. The third state is the tension stretching state: After the fabric is pre-tightened, driven by the equally spaced transmission rod 222, the clamping assemblies 1 on the two end rod holders 225 and each rod holder 225 move towards each other in the corresponding directions at the same time, realizing further stretching and tensioning of the fabric and completing the tension test.

[0024] As Figure 9 shown, the following preferred technical solutions are provided: The clamping assembly 1 includes two clamping plates 11, a connecting plate 12 and a connecting frame 13. The clamping plates 11 are fixedly installed on the connecting plate 12. A gear set 14 is connected between the connecting plate 12 and the connecting frame 13. The connecting frame 13 is fixedly installed on the corresponding rod holder 225. The gear set 14 is rotatably installed on the connecting frame 13. A push rod 15 is connected between one of the connecting plates 12 and the connecting frame 13. Matching pressing strips 16 and pressing grooves 17 are respectively arranged on the two clamping plates 11, and one of the clamping plates 11 is an electromagnet capable of attracting the other clamping plate 11.

[0025] Specifically, in order to solve the technical problem of clamping the two ends of the cloth, the present invention completes the clamping of one end of the cloth by the two clamping plates 11 of the clamping assembly 1. The inspector passes one end of the cloth to be inspected between the two clamping plates 11 of the corresponding clamping assembly 1, and then the clamping mechanism 3 clamps the cloth to the corresponding position of the other clamping assembly 1. The inspector then flattens the two ends of the cloth and passes them through the corresponding clamping assemblies 1 respectively. The push rod 15 pushes the corresponding connecting plate 12 to move, and then uses the meshing gear set 14 to drive the two connecting plates 12 and the clamping plate 11 to clamp each other, and the cloth is clamped by the cooperation between the two clamping plates 11 and the clamping strip 16 and the clamping groove 17 on the clamping plate 11.

[0026] like Figures 3 to 12 As shown, the following preferred technical solutions are provided: The clamping and flipping mechanism 3 includes a transfer seat 31, a support frame 32 and a clamping and flipping assembly 33. The transfer seat 31 is slidably installed on the support frame 32, and the support frame 32 is fixedly installed on the workbench 5. The transfer seat 31 is connected to the driving mechanism in the workbench 5 through a connecting rod group 34. The clamping and flipping assembly 33 is arranged on the transfer seat 31. One end of the connecting rod group 34 is hinged to the transfer seat 31, and the other end is rotatably connected to the driving mechanism.

[0027] Specifically, in order to solve the technical problem of transferring the cloth between the clamping components 1 at both ends, the present invention uses a clamping and flipping component 33 to clamp one end of the cloth, drives the connecting rod group 34 to move through a driving mechanism, and then pushes the transfer seat 31 to slide on the support frame 32, so that the clamping and flipping component 33 can clamp the cloth along the support frame 32, and pass the cloth between each tensioning rod 21 without manual operation, which is quick and convenient.

[0028] like Figures 3 to 12 As shown, the following preferred technical solutions are provided: The clamping and flipping assembly 33 includes a clamping hand 331, a flip rod 332, a flip seat 333 and a cylinder 334. The cylinder 334 and the flip seat 333 are both installed on the transfer seat 31. The clamping hand 331 is fixedly installed on the flip rod 332, and the flip rod 332 is rotatably installed on the flip seat 333. The flip rod 332 and the cylinder 334 are connected by a gear rack set 335. The gear of the gear rack set 335 is fixedly installed on one end of the flip rod 332, and the rack of the gear rack set 335 is slidably installed on the transfer seat 31 through a slide rail 336. The output end of the cylinder 334 is fixedly connected to the rack of the gear rack set 335. A clamping rod 337 is provided on the clamping hand 331.

[0029] Specifically, to solve the technical problems of clamping and transferring the fabric and the gripper 331 flipping away from the fabric after transfer, the present invention uses the gripper 331 to drive the clamping rod 337 to clamp one end of the fabric. After the transfer seat 31 is transferred to the corresponding position and the fabric is clamped by the clamping assembly 1, the gripper 331 releases the fabric, and the air cylinder 334 pushes the rack to move, thereby driving the gear to rotate, causing the flipping rod 332 to rotate 90°, turning the vertical clamping rod 337 on the gripper 331 to horizontal, so that the clamping rod 337 falls out of the area where the fabric is located, avoiding affecting the fabric tension and movement.

[0030] As Figures 2 to 12 shown, the following preferred technical solutions are provided: The pre-tightening mechanism 4 includes a pre-pressing rod 41, a guiding swivel head 42 and a guiding seat 43. The guiding seat 43 is fixedly installed on the support frame 32. The guiding swivel head 42 is slidably connected with the guiding seat 43. The pre-pressing rod 41 is fixedly connected to the guiding swivel head 42, and the pre-pressing rod 41 can abut against the corresponding tensioning rod 21.

[0031] A linear guiding groove 431 and a spiral torsion groove 432 are formed in one end of the guiding seat 43. The guiding groove 431 communicates with the spiral torsion groove 432. The guiding swivel head 42 is slidably connected with the guiding groove 431 and the spiral torsion groove 432. The guiding swivel head 42 is connected with the transfer seat 31 through a rotating rod 433. The rotating rod 433 is rotatably installed on the transfer seat 31, and one end of the rotating rod 433 is fixedly connected to the guiding swivel head 42.

[0032] Specifically, to solve the technical problem of the fabric being tensioned and pre-tightened after being clamped, the present invention uses the movement of the transfer seat 31 to drive the rotating rod 433 and the guiding swivel head 42 to first linearly slide along the guiding groove 431 on the guiding seat 43. After the transfer seat 31 transfers the clamping and flipping assembly 33 to the corresponding position and the clamping and flipping assembly 33 is separated from the fabric, the transfer seat 31 continues to move. At this time, the guiding swivel head 42 slides in the spiral torsion groove 432, so that the pre-tightening rod rotates upward from the horizontal state to a certain angle and abuts against the lower end of the tensioning rod 21, pressing the movable tensioning rod 21 tightly, thereby completing the initial tensioning of the fabric by the tensioning rod 21.

[0033] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments.
