Description

Technical Field

[0001] The present invention relates to the technical field of fabric detection, and specifically relates to a batch sampling and inspection device for children's clothing fabrics and its inspection method. Background Technique

[0002] As a product that directly contacts children's skin, the safety and comfort of the materials of children's clothing directly affect children's health. Therefore, ensuring the color fastness, safety and other physical properties of children's clothing fabrics has become the focus of common concern for manufacturers and consumers. Among them, in the quality inspection of children's clothing fabrics, rubbing color fastness is an important assessment index.

[0003] At present, linear reciprocating friction testers are mainly used in the market, which mainly detect the color stability by simulating the friction situation during the wearing process of the fabric. However, the control of its friction pressure and speed may be affected by human factors, and the results are not stable enough; moreover, during the operation of the moving parts of the existing friction testers, especially in a dry environment, static electricity is easily generated due to friction with the fabric. Static electricity will attract dust or charged particles, which may cause interference to the test environment, thereby affecting the accuracy and repeatability of the test results.

[0017] S2: Then, the lifting cylinder is turned on to make the friction head contact with the fabric to be tested, and then the driving motor is turned on to make the friction head rotate back and forth against the fabric for friction; at the same time, under the cooperation of the driven component and the linkage component, the piston plate transports the solution in the liquid storage tank to the piston cylinder in a timely and quantitative manner, and sprays it to the friction point between the friction head and the test fabric through the nozzle for wetting treatment, so as to achieve an anti-static effect, thereby improving the repeatability and consistency of the experiment.

Based on the results, it is determined whether the friction color fastness of the fabric meets the relevant standards and requirements.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The present invention forms an electric rotary friction test assembly through a driving motor, a rotating shaft, a balancing disc and a friction head. Compared with the traditional linear reciprocating friction tester, it can provide more consistent friction force and speed, reduce human operation errors, and improve the repeatability and reliability of the test results; by setting a spray assembly, it can perform anti-static treatment to a certain extent, which can reduce the interference of the internal circuits and components of the instrument, ensure the normal operation of the electric rotary friction color fastness tester, and improve the long-term operation stability of the equipment.

[0021] 2. The present invention has an ingenious structure and strong mechanical linkage. Through the design of the driven wheel, synchronous wheel, rotating disk, eccentric sliding column, crank and connecting ring, the forward and reverse reciprocating rotational motion of the rotating shaft can be converted into the unidirectional continuous rotational motion of the supporting tube; and through the design of the driving column, driven ring plate, inner gear ring, spur gear and vertical rotating shaft and driving groove, the continuous rotational motion of the supporting tube can be converted into the intermittent piston motion of the piston rod, so that the piston plate can transport the solution in the liquid storage tank to the piston cylinder in a timely and quantitative manner, and spray it to the friction point between the friction head and the test fabric through the nozzle for wetting treatment. Such a setting can not only effectively reduce the generation and accumulation of static electricity, but also improve the performance of the friction process and improve the reliability and consistency of the test results.

[0022] 3. The present invention sets an inclined groove, a cylindrical pin, a push bar, a limit block and a reset spring for use together, so that the two groups of pressure blocks can adaptively lock or loosen the vertical rotating shaft according to the movement state of the support tube. While satisfying the limited insertion of the driven shaft and the vertical rotating shaft, the vertical rotating shaft can be quickly locked after the driven shaft is pulled out of the mounting seat, so that the driven ring plate is stabilized in the previous position, which is convenient for the next docking of the driven shaft and the vertical rotating shaft.

The piston rod of the lifting cylinder 7 extends downward and is fixedly connected with the balance disk 5; and four groups of support tubes 23 distributed in a circular array are fixedly arranged at the lower end of the balance disk 5. A driven shaft 22 is rotatably installed in each group of support tubes 23 in a limited way. The multiple groups of driven shafts 22 are driven by a driven assembly to perform a one-way rotational movement. The driven assembly is powered by the driving motor 3; a mounting seat 8 is arranged directly below the friction head 6. The mounting seat 8 is fixedly arranged on the base 1 through a detachable structure. The mounting seat 8 is provided with an operation hole 802 and a material assembly cavity 801 from top to bottom in sequence.

The linkage assembly is powered by the driven shaft 22.

[0037] Further, the present invention forms an electric rotary friction test assembly through the driving motor 3, the rotating shaft 4, the balance disk 5 and the friction head 6. Compared with the traditional linear reciprocating friction tester, it can provide more consistent friction force and speed, reduce human operation errors, and improve the repeatability and reliability of test results; by setting the spray assembly, antistatic treatment can be carried out to a certain extent, which can reduce the interference of the internal circuit and components of the instrument, ensure the normal operation of the electric rotary friction color fastness tester, and improve the stability of the equipment during long-term operation.

[0038] Such as Figure 1 , Figure 10 and Figure 11As shown, the driving motor 3 is a forward and reverse motor, the output shaft 401 is provided with a limit flange protruding from the outside, the inner wall of the rotating shaft 4 is provided with a vertical guide groove for accommodating the limit flange, the outer part of the rotating shaft 4 is fixedly sleeved with a coupling ring 29, the coupling ring 29 is connected to the driven assembly, the driven assembly includes a driven wheel 24, a synchronous wheel 25, a rotating disk 26, an eccentric sliding column 27 and a crank 28, the upper end of the driven shaft 22 extends into the balancing disk 5 and is fixedly connected to the driven wheel 24. The driven wheel 24 is meshed and connected to the synchronous wheel 25, the synchronous wheel 25 and the rotating disk 26 are rotationally mounted in the balancing disk 5 through the central axis, and a one-way limiting mechanism is also provided on the central axis, the one-way limiting mechanism adopts a ratchet mechanism, so that the central axis can only perform rotational movement in one direction; the upper end surface of the rotating disk 26 is eccentrically provided with an eccentric sliding column 27, the eccentric sliding column 27 is clamped in the crank 28, and the crank 28 is fixedly connected to the coupling ring 29.

[0039] Furthermore, by arranging the driven wheel 24, the synchronous wheel 25, the rotating disk 26, the eccentric sliding column 27, the crank 28 and the connecting ring 29 for use in cooperation, the forward and reverse reciprocating rotational motion of the rotating shaft 4 can be converted into the unidirectional continuous rotational motion of the supporting tube 23;

[0040] Specifically, by turning on the drive motor 3, its output shaft 401 drives the rotating shaft 4 to perform forward and reverse reciprocating rotational motion, so that the connecting ring 29 drives the crank 28 to swing left and right. Since a one-way limiting mechanism is provided on the central shaft, when the crank 28 swinging left and right acts on the eccentric sliding column 27, the rotating disk 26 drives the synchronous wheel 25 to perform one-way continuous rotational motion, and the synchronous wheel 25 acts on the driven wheel 24, so that the driven shaft 22 drives the support tube 23 to also perform continuous rotational motion.

[0041] like Figure 6 , Figure 9 as well as Figure 10 As shown, the lower end of the driven shaft 22 extends into the mounting seat 8 and is connected to the linkage assembly, which includes a toggle column 17, a driven ring plate 18, an inner gear ring 19, a spur gear 20 and a vertical shaft 21. The driven ring plate 18 is mounted in the mounting seat 8 for limited rotation. A driving groove 1801 is provided on the outer wall of the driven ring plate 18. The driving groove 1801 consists of a V-shaped wheel groove and a linear wheel groove. The V-shaped wheel groove and the linear wheel groove are arranged in four groups and are spaced apart from each other. One end of the toggle column 17 is fixedly arranged on the top of the piston rod 14, and the other end of the toggle column 17 is clamped in the driving groove 1801. The inner gear ring 19 is fixedly arranged on the inner side wall of the driven ring plate 18. The vertical shaft 21 is mounted in the mounting seat 8 for limited rotation. The outer part of the vertical shaft 21 is fixedly sleeved with a spur gear 20, which is meshed and connected to the inner gear ring 19.

[0042] Furthermore, by setting the toggle post 17, the driven ring plate 18, the internal gear ring 19, the spur gear 20 and the vertical rotating shaft 21 to cooperate with the driving groove 1801, the continuous rotational movement of the support tube 23 can be converted into the intermittent piston movement of the piston rod 14, so that the piston plate 13 can regularly and quantitatively transport the solution in the liquid storage tank 10 into the piston cylinder 12, and atomize and spray it onto the friction area between the friction head 6 and the test fabric through the nozzle 16 for wetting treatment, thereby achieving the effect of anti-static electricity;

[0043] Specifically, the support tube 23 acts on the vertical rotating shaft 21, and the spur gear 20 coaxially and fixedly connected to the vertical rotating shaft 21 acts on the internal gear ring 19, so that the internal gear ring 19 drives the driven ring plate 18 to perform continuous and slow rotational movement. The driving groove 1801 on the driven ring plate 18 acts on the toggle post 17, and the toggle post 17 repeatedly enters the straight wheel groove from the V-shaped wheel groove and then enters the V-shaped wheel groove from the straight wheel groove, and reciprocates in this way, so that the toggle post 17 drives the piston rod 14 to perform intermittent piston movement; the piston rod 14 pushes the piston plate 13, and a one-way valve is arranged on the piston plate 13, so that the piston plate 13 can regularly and quantitatively transport the solution in the liquid storage tank 10 into the piston cylinder 12, and spray it onto the friction area between the friction head 6 and the test fabric through the nozzle 16 for wetting treatment.

[0044] As Figure 3 and Figure 2 shown, a circular hole for accommodating the driven shaft 22 is provided on the upper surface of the mounting seat 8, a cylindrical cavity for accommodating the driven shaft 22 is provided on the upper end surface of the vertical rotating shaft 21, three groups of radially guiding strips distributed in an annular array protrude from the inner wall of the cylindrical cavity, and a long sliding groove for accommodating the radially guiding strips is provided on the outer wall of the lower half of the driven shaft 22.

[0045] Furthermore, by setting the radially guiding strips to cooperate with the long sliding groove, on the one hand, it is convenient for the alignment and clamping of the driven shaft 22 and the vertical rotating shaft 21, and on the other hand, it plays a role in axial limiting, so that the vertical rotating shaft 21 can rotate together with the driven shaft 22.

[0046] As Figure 5 and Figure 8 shown, a set of pressing blocks 30 are arranged at both the front and rear ends of the vertical rotating shaft 21. The pressing blocks 30 are installed in the mounting seat 8 in a limiting and sliding manner. The side of the pressing block 30 close to the vertical rotating shaft 21 is set as an arc surface. An inclined groove 31 is penetrated through the side wall of the pressing block 30, a cylindrical pin 32 is inserted in the inclined groove 31, the cylindrical pin 32 is fixedly connected to the pushing bar 33, a limiting block 34 is fixedly connected to the side wall of the pushing bar 33, a return spring 35 is fixedly arranged at the lower end of the limiting block 34, and the upper end of the pushing bar 33 extends out of the upper end surface of the mounting seat 8 and is in contact connection with the lower end surface of the support tube 23.

[0047] Furthermore, by setting the inclined groove 31, the cylindrical pin 32, the pushing bar 33, the limit block 34 and the return spring 35 for use together, the two groups of pressure blocks 30 can adaptively lock or loosen the vertical rotating shaft 21 according to the movement state of the support tube 23, while satisfying the limited insertion of the driven shaft 22 and the vertical rotating shaft 21, and after the driven shaft 22 is pulled out of the mounting seat 8, the vertical rotating shaft 21 can be quickly locked, so that the driven ring plate 18 is stabilized in the previous position, which is convenient for the next docking of the driven shaft 22 and the vertical rotating shaft 21.

[0048] like Figure 3 as well as Figure 2 As shown, the operation hole 802 is composed of an upper circular hole and a lower prism hole, and the nozzle 16 is arranged on the inclined side wall of the prism hole, and is arranged through the left side, the front side and the right side of the material assembly chamber 801. The nozzle 16 is an atomizing nozzle 16, and such arrangement facilitates the nozzle 16 to be just aligned with the friction port.

[0049] like Figure 3 As shown, the outer wall of the mounting seat 8 is provided with a nut seat 9 and an auxiliary pressure frame 36 in sequence. The auxiliary pressure frame 36 is slidably installed on the mounting seat 8, and an adjusting screw 37 is rotatably installed on the upper limit of the auxiliary pressure frame 36. The nut seat 9 is fixedly set on the side wall of the mounting seat 8, and the upper end of the adjusting screw 37 passes through the nut seat 9 and is fixedly connected to a rotating wheel.

[0050] Specifically, by turning the adjusting screw 37, the inner and outer threads rotate together to drive the auxiliary pressing frame 36 to move up and down, thereby pressing or loosening the fabric to be tested.

[0051] When the present invention is in use: first, place the fabric to be tested flatly in the material assembly chamber 801, then, by turning the adjusting screw 37, the rotation of the internal and external threads drives the auxiliary pressure frame 36 to move downward, thereby pressing the fabric to be tested; then, by opening the lifting cylinder 7, the balancing disc 5, the rotating shaft 4 and the friction head 6 are driven to move downward together; until the support tube 23 just contacts the mounting seat 8, and the friction head 6 also contacts the fabric to be tested, then, by turning on the driving motor 3, the output shaft 401 thereof drives the rotating shaft 4 to perform forward and reverse reciprocating rotational motion, so that the friction head 6 performs forward and reverse reciprocating rotational friction against the fabric; at the same time, the connecting ring 29 drives the crank 28 to swing left and right. Since a unidirectional limiting mechanism is provided on the central shaft, when the crank 28 swinging left and right acts on the eccentric sliding column 27, the rotating disc 26 drives the synchronous wheel 25 to perform unidirectional continuous rotational motion, and the synchronous wheel 25 acts on the driven wheel 2 4, so that the driven shaft 22 drives the support tube 23 to perform continuous rotational motion, the support tube 23 acts on the vertical rotating shaft 21, and the spur gear 20 coaxially fixedly connected with the vertical rotating shaft 21 acts on the inner gear ring 19, so that the inner gear ring 19 drives the driven ring plate 18 to perform continuous and slow rotational motion, and the driving groove 1801 on the driven ring plate 18 acts on the toggle column 17, and the toggle column 17 repeatedly enters the linear wheel groove from the V-shaped wheel groove, and then enters the V-shaped wheel groove from the linear wheel groove, and reciprocates here, so that the toggle column 17 drives the piston rod 14 to perform intermittent piston motion, and the piston rod 14 pushes the piston plate 13, and the piston plate 13 is provided with a one-way valve, so that the piston plate 13 can transport the solution in the liquid storage tank 10 to the piston cylinder 12 in a timely and quantitative manner, and spray it to the friction point between the friction head 6 and the test fabric through the nozzle 16 for wetting treatment, so as to achieve an anti-static effect, thereby improving the repeatability and consistency of the experiment.

[0052] A batch sampling inspection method for children's clothing fabrics is adopted in a batch sampling inspection device for children's clothing fabrics. The method comprises the following steps:

[0053] S1: First, place the fabric to be tested flat in the material assembly chamber 801, and then turn the adjusting screw 37 to drive the auxiliary pressing frame 36 to move downward under the action of the internal and external threads, thereby pressing the fabric to be tested;

[0054] S2: Then, by turning on the lifting cylinder 7, the friction head 6 is brought into contact with the fabric to be tested, and then by turning on the driving motor 3, the friction head 6 is caused to perform forward and reverse reciprocating rotation and friction against the fabric; at the same time, under the cooperation of the driven component and the linkage component, the piston plate 13 transports the solution in the liquid storage tank 10 to the piston cylinder 12 in a timely and quantitative manner, and sprays it to the friction point between the friction head 6 and the fabric to be tested through the nozzle 16 for wetting treatment, thereby achieving an anti-static effect, thereby improving the repeatability and consistency of the experiment.

[0055] S3: After a certain number of friction cycles are completed, turn off the drive motor 3, and the friction head 6 stops rotating. At the same time, turn on the lifting cylinder 7 again to withdraw the friction head 6 from the mounting seat 8, and take out the fabric after friction treatment for visual evaluation or color difference measurement. According to the results, determine whether the rubbing fastness of the fabric meets the relevant standards and requirements.

[0056] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
