Description

Technical Field

[0001] The utility model relates to the field of deformation wire testing, in particular to an integrated deformation wire curling testing device. Background Art

[0002] Deformed yarns utilize the thermoplastic deformation properties of synthetic fibers. Under the action of mechanical, thermal or high-pressure air, the fiber bundles that were originally separated in the straight state are processed into yarns with curled shapes and elasticity. The curl shrinkage rate reflects the shrinkage rate caused by the recovery of the curled three-dimensional structure of the deformed yarn after being straightened. It has an important influence on the shrinkage performance, softness and stiffness of the fabric. The curling test device is used to measure the curling shrinkage of the deformed yarn. There are many types of curling test devices on the market today, which can basically meet people's needs, but there are still certain problems.

[0003] First of all, from the perspective of space and safety, firstly, the crimping machine on the market consists of three parts: an oven, a wire frame, and a length test bench. The three parts are placed independently, and the effective utilization rate of space is low. The heating space of the oven is much larger than the volume of the yarn frame, which is not conducive to energy saving and environmental protection. Secondly, when the oven is used for dry heat treatment of the filament, the high temperature will cause burns to the users.

[0004] Secondly, from the perspective of test accuracy, firstly, the vertical ruler is a tool for measuring the curling length of the deformed wire. When the operator uses it, the control of the stretching time and the visual reading are not accurate enough, which will reduce the repeatability of the test due to operation; secondly, the weights provide constant tension for the curling device, but during use, the limbs will knock over or drop the stand-by weights, and the rated weight mass will be lost, resulting in erroneous test results.

The drying chamber 21 is opened inside the oven body 11, and the test base 22 is installed on the outer wall of the oven body 11. The yarn frame 12 is normally placed on the test base 22. When it is necessary to test the curling shrinkage rate of the deformed yarn at a certain temperature, the yarn frame 12 with the deformed yarn suspended thereon is placed in the drying chamber 21 and heated for a certain time.

[0027] like Figure 1 As shown, two groups of telescopic devices are provided inside the oven body 11, and each group of the telescopic devices includes a plurality of slide bars 31 connected in sequence, and two adjacent slide bars 31 are slidably connected to each other, and the bottom slide bar 31 is fixedly connected to the bottom wall of the oven, and a placement plate 32 for fixing the yarn frame 12 is fixedly installed between the two top slide bars 31; by setting the telescopic device, the telescopic device is composed of a plurality of slide bars 31 connected in sequence, and the placement plate 32 is installed between the top slide bars 31, and the placement plate 32 can be used to place the yarn frame 12.

When the insulating door 41 is closed, the overall height of the multiple slide rods 31 will be reduced, and when it is opened, the overall height of the multiple slide rods 31 will be increased, which is convenient for taking and placing the yarn frame 12.

[0029] like Figure 3 and Figure 4 As shown, a plurality of first magnetic strips 51 are respectively installed on the top of the placement plate 32 and the test base 22, and a plurality of second magnetic strips 52 are installed on the bottom of the placement base 23, and the first magnetic strips 51 and the second magnetic strips 52 are arranged opposite to each other; the first magnetic strips 51 and the second magnetic strips 52 are arranged opposite to each other, so that the yarn frame 12 can be easily switched to the placement plate 32 or the test base 22, which is convenient for operation.

[0030] like Figure 1 As shown, a plurality of receiving grooves 6 for placing weights 13 are provided on the top of the placement base 23; by providing the receiving grooves 6, the receiving grooves 6 can facilitate the placement of the weights 13, and the receiving grooves 6 are opened on the yarn frame 12, so as to facilitate hanging the weights 13 on the deformed yarn, which is convenient for use.

[0031] like Figure 1 As shown, the middle and upper parts of the two side frames 24 are slidably connected with a grip rod 7; by setting the grip rod 7, the grip rod 7 can conveniently lift the yarn frame 12 and conveniently switch the position of the yarn frame 12; more specifically, the outside of the grip rod 7 is wrapped with heat insulation fiber to avoid burns when taking out the yarn frame.

[0032] like Figure 6As shown, a fixing block 81 is installed on the top wall of the oven body 11 and on one side of the heat insulation door 41, a slide groove 82 is provided inside the fixing block 81, a plug rod 83 is slidably connected inside the slide groove 82, a guide rod 84 is connected to the other end of the plug rod 83, a limit plate 85 is fixedly provided in the middle of the guide rod 84, a limit plate 86 is fixedly provided on one side of the fixing block 81, and a spring 87 is sleeved on the outer side of the guide rod 84 and between the limit plate 86 and the limit plate 85; By setting a fixed block 81, the fixed block 81 is installed on the top wall of the oven body 11, the slide groove 82 is opened on the fixed block 81, the insertion rod 83 is in contact with the heat-insulating door 41, which can prevent the heat-insulating door 41 from closing by itself, and the guide rod 84 is fixedly connected to the insertion rod 83.

As the insulation door 41 is opened, the distance between the cable box 43 and the slide bar 31 will gradually increase, and the overall height of the multiple slide bars 31 will gradually increase, so that the placement plate 32 will be raised, and then the yarn frame 12 is removed from the test base 22 and placed on the placement plate 32. After the placement is completed, the insulation door 41 is closed, and the distance between the cable box 43 and the slide bar 31 will be reduced, and the overall height of the multiple slide bars 31 will also be reduced accordingly. When the insulation door 41 is completely closed, the deformed yarn inside the drying chamber 21 is subjected to dry heat treatment at the required test temperature. At this time, the deformed yarn will be deformed by the heat. After a certain period of time, the insulation door 41 is opened, and the yarn frame 12 is taken out and replaced on the test base 22. After a short delay, the laser rangefinder 27 is used to measure the distance L1 between it and the weight 13. After cooling for a certain period of time, the laser rangefinder 27 is used to test the distance L2 between it and the weight again. The deformed yarn length LG can be calculated from L1, and the deformed yarn length LZ can be calculated from L2. (LG-LZ) / LG*100% is the curling shrinkage rate of this deformed yarn.
