Technical Field
[0001] The utility model relates to the technical field of testing machines, in particular to a full-automatic shrinkage testing machine. Background Art
[0002] With the improvement of living standards, people have stricter requirements for product quality. Fabric clothing is closely related to people's daily life, and people have stricter requirements on clothing quality, stability and other indicators. Fabric shrinkage is an important performance indicator of fabric clothing. The maximum dimensional change of fabric clothing after washing and drying can be determined by shrinkage, which can also reflect the stability of clothing dimensions. The fully automatic shrinkage tester is an important testing tool for testing fabric shrinkage. To ensure the accuracy of the data, the stability, repeatability and reliability of the equipment are extremely critical.
[0003] The test can be carried out by washing the fabric in different water temperatures and repeatedly stirring the fabric to produce new deformation. During the washing test, the dimensional changes caused by external forces are increased, thereby improving the test efficiency.
[0004] There are now fully automatic shrinkage testers that connect the outer cylinder and the drive motor through the base, so that the inner cylinder rotates at high speed and the outer cylinder is limited; the outer cylinder is vertically supported by springs to reduce the centripetal force generated by the sample rotating along the cylinder wall during washing, thereby reducing the vibration of the equipment.
[0005] At present, the following problems still exist: 1. The fully automatic shrinkage tester vibrates at high frequencies during the test, causing displacement of the equipment;
[0006] 2. The fully automatic shrinkage testing machine does not have a limit device during the test, which causes interference between the equipment's motion module and the frame.
[0007] Aiming at the above problems, improvements are proposed. Utility Model Content
[0008] The utility model provides a fully automatic shrinkage tester which can be used to measure the shrinkage and relaxation of various cotton, wool, linen, silk, chemical fiber fabrics, clothing or other textiles after washing, and solves the above problems existing in the use process of the prior art.
[0009] The technical solution of the present utility model is achieved as follows:
[0010] A fully automatic shrinkage testing machine comprises a base and a box body, wherein the box body is arranged on the base, a roller assembly is arranged in the box body, and the roller assembly includes a roller detection inner accommodating chamber, and is characterized in that a first support and a second support are installed in the box body, the first support and the second support are arranged at the lower end of the box body, the first support and the second support are arranged separately, a first shock-absorbing unit is provided between the first support and the base, and a second shock-absorbing unit is provided between the second support and the base, a limiting mechanism is also installed between the first support and the second support and the box body, and an angular limiting mechanism is provided on the side of each first shock-absorbing unit and the second shock-absorbing unit.
[0011] Preferably, the first shock absorbing unit and the second shock absorbing unit are distributed on both sides with the middle of the box as the center, and two of the first shock absorbing unit and the second shock absorbing unit are provided.
[0012] Preferably, a spring base is installed on the base, and an upper spring mounting seat is provided on the first support and the second support. A spring mounting space is formed between the spring base and the upper spring mounting seat, and the first shock absorbing unit and the second shock absorbing unit are provided on the spring mounting space.
[0013] Preferably, the spring base has a mounting support and a conical boss protruding upward along the end surface of the mounting support, and a limiting boss and a mounting hole are provided at the bottom of the mounting support.
[0014] Preferably, the first shock absorbing unit and the second shock absorbing unit both use springs.
[0015] Preferably, the upper spring mounting seat adopts the same structure as the spring base.
[0016] Preferably, the first shock absorbing unit and the second shock absorbing unit are symmetrically arranged
[0017] Preferably, the limiting mechanism is arranged in an oblique manner and connected between the first support, the second support and the box body.
[0018] In summary, the fully automatic shrinkage testing machine disclosed in the present invention has the following beneficial effects:
[0019] 1. The balancing device is supported by an eight-shaped angle, and the motion module is supported by four springs. The eight-shaped angle support structure has a good load-bearing capacity and is the most stable force-bearing structure. During the high-speed dehydration test, the sample rotates along the wall of the cylinder as the inner cylinder rotates at high speed. When the speed reaches high speed, the motion module becomes centrifugal under the action of inertia. The springs balance the centripetal force with the angle support to achieve a balanced state. When the equipment is running at high speed in the balanced state, the vibration is reduced and the whole machine operates stably, solving the displacement caused by equipment vibration.
[0020] 2. To prevent interference between the motion module and the frame, multiple gas spring limiters were added between the motion module and the equipment to minimize frictional resistance and achieve multi-coordinate positioning of the motion module. The multi-point limiter uses an angular support structure to limit the motion module at four positions: front, back, left, and right. During high-frequency movement of the equipment, the angular support balance device can only provide a shock-absorbing effect and cannot limit the motion module to a certain range. The addition of the multi-point limiter not only ensures better shock absorption during the motion module's movement, but also allows the motion module to move only within the designed area, thus resolving the interference problem.
[0021] To solve the vibration and interference problems, the drive motor is replaced and the rotation position of the inner cylinder is shifted toward the rotation center to achieve a force balance effect, reduce the impact during high-speed rotation, and increase the rotation speed to the predetermined value.

[0028] The following is a combination of the appended examples of the present invention Figure 1-5 , clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention. Example
[0029] like Figures 1 to 5 As shown, this embodiment discloses a fully automatic shrinkage testing machine, comprising a base 100 and a housing 104. The housing is mounted on the base and contains a roller assembly 106. The roller assembly includes a roller detection chamber for measuring the shrinkage and relaxation of items to be tested, such as various cotton, wool, linen, silk, chemical fiber fabrics, clothing, or other textiles, after washing. A first support 102 and a second support 103 are mounted on the housing. The first and second supports 102 and 103 are located at the lower end of the housing 104 and are spaced apart. In this embodiment, the first and second supports are symmetrically arranged below the housing 104 to improve testing stability. A first damping unit 101 is located between the first support and the base, and a second damping unit is located between the second support and the base. The first and second damping units have identical structures. A limiting mechanism is also installed between the first and second supports and the housing. Each first and second damping unit has an angled limiting mechanism on its side. Both the first and second damping units utilize springs. The function of the limit mechanism: In order to avoid interference between the motion module and the frame, multiple gas spring limit devices (limit mechanisms) are added between the motion module and the equipment to minimize friction resistance and realize multi-coordinate limit of the motion module.
[0030] The above 1. uses an eight-shaped angle to support the balancing device, and uses four springs to support the motion module. The eight-shaped angle support structure has a good load-bearing capacity and is the most stable force-bearing structure. During the high-speed dehydration test, the sample rotates along the wall of the inner drum as the inner drum rotates at high speed. When the speed reaches high speed, the motion module becomes centrifugal under the action of inertia. The springs balance the centripetal force with the angle support to achieve a balanced state. When the equipment is running at high speed in the balanced state, the vibration is reduced and the whole machine operates stably, solving the displacement caused by equipment vibration.
[0031] In order to further improve stability, the first shock absorbing unit 101 and the second shock absorbing unit are distributed on both sides with the middle of the box as the center, and two first shock absorbing units and two second shock absorbing units are provided. The first shock absorbing unit and the second shock absorbing unit are symmetrically arranged.
[0032] A spring base 107 is installed on the base, and an upper spring mounting seat is provided on the first support and the second support. A spring mounting space D is formed between the spring base and the upper spring mounting seat, and the first shock absorbing unit and the second shock absorbing unit are provided on the spring mounting space D.
[0033] The spring base has a mounting support 1071 and a tapered boss 1072 protruding upward along the end surface of the mounting support. The bottom of the mounting support 1071 is provided with a limit boss 1074 and a mounting hole 1073. The specific installation method is that the lower end of the spring is clamped in the tapered boss 1072, and this structure is also convenient for installation.
[0034] The structure of the upper spring mounting seat is the same as that of the spring base.
[0035] The limiting mechanism is set up in an oblique manner and connected between the first support and the second support and the box body. The limiting mechanism adopts a gas spring structure, which is mainly distributed in four positions, front, back, left and right, for limiting.
[0036] The multi-point limit device uses an angular support structure to limit the motion module at four positions: front, back, left, and right. When the equipment moves at high frequencies, the angular support balance device can only provide a shock absorption effect and cannot ensure that the motion module moves within a certain range. The addition of the multi-point limit device can not only ensure that the motion module has a better shock absorption effect during movement, but also can prevent the motion module from moving within the designed area, thus solving the interference problem.
[0037] This solution addresses vibration and interference issues by replacing the drive motor and shifting the inner drum's rotational position toward the center of rotation to achieve a force balance effect, reducing impact during high-speed rotation and increasing the speed to a predetermined value. This solution achieves the following: 1. An eight-angle support balancing device eliminates vibration and displacement during high-speed dehydration; 2. A multi-point limiter prevents the drum from shifting and colliding with the frame during operation; 3. The maximum dehydration speed is increased to 1100 r / min, improving testing efficiency.
[0038] It also solves the current problems that due to the thin spring, the drum cannot be fixed and causes large-scale shaking. The spring is too thick and the equipment will vibrate greatly during high-frequency washing and cannot play a shock-absorbing effect. The equipment will shift due to high-frequency resonance during the test; even a violent collision will cause damage to the equipment. Any of these situations will affect the test results, making the test results invalid.
[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
