Description

Technical Field

[0001] This utility model relates to the technical field of tensile testing devices, and in particular to a tensile testing device for textile fabrics. Background Technology

[0002] After processing, textile fabrics need to undergo tensile testing to ensure the overall quality of the fabrics.

[0003] In existing technologies, tensile testing devices generally use two clamps to hold both ends of the fabric, and then use a drive unit to pull the clamps along the fabric's stretching direction to perform tensile testing. However, for current vertical tensile testing devices, the fabric needs to be installed vertically on the tensile testing device, and the clamping operation of both ends of the fabric on the tensile testing device is difficult, making it easy to maintain the flatness of the fabric positioning, which can easily affect the quality of the fabric tensile testing. Therefore, a textile fabric tensile testing device that facilitates clamping and positioning of the fabric in a vertical state is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a textile fabric tensile testing device to solve the problems mentioned in the background art.

[0007] A traction mechanism is located on the top of the base and is used for vertical movement of the upper clamp.

[0008] Preferably, the upper clamp includes a clamping seat, the bottom end of which is provided with a clamping groove, and the feeding mechanism includes an arcuate channel on the top of the front side of the clamping seat, one end of which is connected to the clamping groove.

Detailed Implementation

[0020] 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.

[0021] This utility model provides, for example Figure 1-4 The illustrated textile fabric tensile testing device includes a base 100 and a traction mechanism. A lower clamp is fixedly mounted on the bottom inner side of the base 100, and an upper clamp 200 is movably mounted above the lower clamp. A feeding mechanism is mounted on the upper clamp 200 for feeding the fabric onto the upper clamp 200. The traction mechanism is located at the top of the base 100 and is used for vertical movement of the upper clamp 200. By feeding one end of the fabric through the feeding mechanism on the upper clamp 200, the fabric is continuously moved vertically downwards from below the upper clamp 200 with the assistance of the feeding mechanism until... The fabric is positioned between the upper and lower clamps by entering the lower clamp. The top and bottom of the fabric are then held in place by the upper and lower clamps, keeping the fabric vertical. This makes the fabric loading and positioning operation between the upper and lower clamps more convenient, efficient, time-saving, and labor-saving, thus improving work efficiency. It also helps to improve the quality of the fabric positioning between the upper and lower clamps. Finally, the upper clamp 200 is driven vertically upward by the traction mechanism to provide traction force to the fabric for stretch testing.

[0022] In a preferred embodiment, the lower clamp includes a concave frame 102, a first clamping plate 103 is movably disposed on the inner side of the concave frame 102, and a first cylinder 104 is fixedly connected to the back of the concave frame 102. The telescopic end of the first cylinder 104 extends to the inner side of the concave frame 102 and is fixedly connected to the outer wall of the first clamping plate 103. After the bottom of the fabric moves vertically downward into the concave frame 102, the first cylinder 104 only needs to be activated to drive the first clamping plate 103 to move towards the inner wall of the concave frame 102, so as to clamp the bottom of the fabric in conjunction with the inner wall of the concave frame 102, thereby achieving the locking and fixing of the bottom position of the fabric.

[0023] It should be noted that the upper clamp 200 includes a clamping base 201, the bottom end of which has a clamping groove 202. The feeding mechanism includes an arcuate channel 205 on the top of the front side of the clamping base 201, one end of which is connected to the clamping groove 202. Figure 4 As shown, the cross-section of the arc channel 205 is curved. The fabric extends into the arc channel 205 from the front of the clamp 201. Utilizing the guiding effect of the arc corner of the inner wall of the arc channel 205, the fabric can bend and extend vertically downwards as it extends. Moreover, the fabric can pass through the clamping groove 202 of the clamp 201 without the operator having to manually adjust the fabric position. This also avoids the situation where the upper clamp 200 pinches the hand when positioning the fabric, providing high safety protection. The fabric loading operation is convenient, and the vertical positioning of the fabric is accurate, improving the convenience and efficiency of loading the fabric before vertical tensile testing.

[0024] Furthermore, a second clamping plate 203 is movably provided in the clamping groove 202, and a second cylinder 204 is fixedly connected to the back of the clamping seat 201. The telescopic end of the second cylinder 204 extends into the clamping groove 202 and is fixedly connected to the outer wall of the second clamping plate 203. After the fabric is fed into the arc channel 205, the second clamping plate 203 can be moved by driving the second cylinder 204 to clamp the top of the fabric in conjunction with the inner wall of the clamping groove 202. Then, the bottom of the fabric can be clamped by the lower clamp, so that the top and bottom positions of the fabric can be clamped and fixed in a vertical state.

[0025] Furthermore, a base 100 is fixedly connected to the bottom of the gantry support 101. Settlement holes are provided at the corners of the base 100. A linear slide groove 105 is provided on the inner side wall of the gantry support 101. A guide slider 106 is slidably connected to the inner side of the linear slide groove 105. One end of the guide slider 106 is fixedly connected to the outer wall of the clamp 201. The linear slide groove 105 and the guide slider 106 can limit and guide the vertical lifting process of the clamp 201, thereby improving the stability of the clamp 201 during movement.

[0026] In addition, the traction mechanism includes a traction device 300, which is fixedly connected to the top of the gantry support 101. The telescopic end of the traction device 300 extends to the inside of the gantry support 101, and a tension sensor 301 is fixedly connected between the telescopic end of the traction device 300 and the clamp 201. The traction device 300 generally uses a hydraulic cylinder. By controlling the amount of hydraulic oil entering and exiting the hydraulic cylinder through a solenoid valve, the traction distance of the traction device 300 can be controlled. Thus, the upper clamp 200 can be driven to move vertically through the traction device 300 to stretch the fabric. With the tension sensor 301 detecting the magnitude of the traction force, the stretching detection of the fabric can be achieved.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
