Description

Technical Field

[0001] This application relates to the field of textile testing technology, specifically a constant pressure textile pilling tester. Background Technology

[0002] In the field of quality inspection of textiles and leather products, pilling is a key indicator for evaluating product durability and appearance retention. Its test results directly affect the product's market competitiveness and applicability. Currently, commonly used pilling testing equipment in the industry relies heavily on manual adjustment of the pressure between the grinding head and the sample. This is not only cumbersome and inefficient, but also makes it difficult to achieve precise and constant pressure control. During long-term testing, traditional equipment is prone to pressure fluctuations due to changes in frictional resistance caused by the reciprocating motion of the grinding head and component deformation. This affects the accuracy and repeatability of the test data. Some equipment requires additional tools for pressure adjustment, which is inconvenient and carries the risk of component damage. Furthermore, adjustment mechanisms lacking a stable support structure are prone to loosening and shifting after high-frequency use, further reducing equipment reliability, increasing maintenance costs, and failing to meet the modern textile testing requirements for efficient, accurate, and stable testing. Utility Model Content

Some devices require additional tools to adjust the pressure, which is inconvenient to operate and poses a risk of component damage. Adjustment mechanisms that lack a stable support structure are prone to loosening and displacement after high-frequency use, further reducing equipment reliability, increasing maintenance costs, and failing to meet the modern textile testing requirements for efficient, accurate, and stable testing.

[0006] Preferably, a positioning plate is fixedly connected to the surface of the screw, and the surface of the positioning plate is in contact with the top of the mounting plate.

[0015] 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.

[0016] Please see Figure 1-3 A constant pressure textile pilling tester includes a vacuum adsorption stage 1, a vertical frame 2 fixedly connected to the rear side of the vacuum adsorption stage 1, a lifting frame 3 movably connected to the front side of the vertical frame 2, a motor 4 fixedly connected to the right side of the lifting frame 3, the output end of the motor 4 extending into the interior of the lifting frame 3, a reciprocating lead screw 5 fixedly connected to the output end of the motor 4, a moving block 6 threadedly connected to the left side of the surface of the reciprocating lead screw 5, a hollow cylinder 7 fixedly connected to the bottom of the moving block 6, a constant pressure rod 8 disposed inside the hollow cylinder 7, a pressure sensor 9 fixedly connected to the bottom of the constant pressure rod 8, a data display and operation panel 10 fixedly connected to the front side of the vacuum adsorption stage 1, a moving plate 11 fixedly connected to the bottom of the pressure sensor 9, a compass head grinder 12 fixedly connected to the bottom of the moving plate 11, and a constant pressure adjustment mechanism fixedly connected to the top of the constant pressure rod 8.

[0017] Please see Figure 1-3 The constant pressure regulating mechanism includes a spring 131, which is fixedly connected to the top of the constant pressure rod 8. An adjusting block 132 is fixedly connected to the top of the spring 131. A transmission block 133 is fixedly connected to the right side of the adjusting block 132. The right side of the transmission block 133 extends to the right side of the hollow cylinder 7. A screw 134 is threadedly connected to the inside of the transmission block 133. A mounting plate 135 is sleeved on the surface of the screw 134. The left side of the mounting plate 135 is fixedly connected to the right side of the hollow cylinder 7.

[0018] Furthermore, by setting up a constant pressure regulating mechanism, the operator can rotate the screw 134 to drive the transmission block 133 to move up and down, thereby adjusting the degree of compression of the spring 131 by the regulating block 132, and achieving fine adjustment of the test pressure.

[0019] Please see Figure 1-3A positioning piece 14 is fixedly connected to the surface of the screw 134, and the surface of the positioning piece 14 contacts the top of the mounting plate 135.

[0020] Furthermore, by setting the positioning plate 14, the downward stroke of the screw 134 can be precisely limited, preventing the operator from excessively compressing the spring 131 due to excessive downward movement when rotating the screw 134 to adjust the pressure, which could cause the test pressure to exceed the set range or damage components such as the constant pressure rod 8 and the spring 131.

[0021] Please see Figure 1-3 A stabilizing sleeve 15 is fitted on the top of the surface of the screw 134, and the top of the stabilizing sleeve 15 is fixedly connected to the bottom of the moving block 6.

[0022] Furthermore, the stabilizing sleeve 15 guides and supports the up-and-down movement of the screw 134, preventing the screw 134 from shaking or tilting during rotation and movement, and avoiding uneven force on the transmission block 133 due to the offset of the screw 134, which would affect the accuracy of pressure regulation.

[0023] Please see Figure 1-3 A knob 16 is fixedly connected to the bottom of the surface of the screw 134, and the knob 16 is located at the bottom of the mounting plate 135.

[0024] Furthermore, by setting the knob 16, the operator can directly rotate the knob 16 by hand to drive the screw 134 to rotate without the need for additional tools, making the operation more convenient and labor-saving. In test scenarios where pressure parameters need to be adjusted frequently, the adjustment time can be greatly shortened, the operating efficiency can be improved, the risk of damage to the screw 134 or equipment due to improper use of tools can be reduced, and the ease of use of the equipment can be improved.

[0025] Please see Figure 1-3 The front and rear sides of the bottom of the mounting plate 135 are fixedly connected with reinforcing ribs 17, and the surface of the reinforcing ribs 17 is fixedly connected to the surface of the hollow cylinder 7.

[0026] Furthermore, by setting the reinforcing ribs 17, the pressure and torque borne by the mounting plate 135 are effectively dispersed, avoiding problems such as deformation, loosening or even breakage of the mounting plate 135 due to long-term stress, ensuring the overall stability of the constant pressure regulating mechanism, ensuring the reliability of the equipment in long-term, high-frequency use, and reducing maintenance costs.

[0027] Please see Figure 1-3 Each of the four corners of the bottom of the movable plate 11 is hinged with a limiting pulley 18, which is located at the top of the vacuum adsorption stage 1.

[0028] Furthermore, by setting the limiting pulley 18, when the moving plate 11 reciprocates with the moving block 6, the pulley rolls into contact with the top of the vacuum adsorption stage 1, converting the sliding friction between the moving plate 11 and the adsorption stage into rolling friction, greatly reducing the motion resistance, making the reciprocating motion of the moving plate 11 driven by the moving block 6 smoother, avoiding the increase in load on the motor 4 or the fluctuation of the motion speed due to excessive resistance, and ensuring the stability of the test process.

[0029] The specific implementation process of this utility model is as follows: When in use, the leather is placed on the top of the vacuum adsorption table 1, the vacuum adsorption table 1 is started to fix it, the vertical frame 2 is operated to adjust the lifting frame 3 to descend, the lifting frame 3 drives the compass head grinder 12 to descend, when the compass head grinder 12 contacts the leather, the pressure sensor 9 generates a parameter signal and transmits it to the data display operation panel 10, the motor 4 is started, the motor 4 drives the reciprocating screw 5 to rotate, the reciprocating screw 5 drives the moving block 6, the hollow cylinder 7, the constant pressure rod 8 and the compass head grinder 12 to move back and forth on the top of the leather; When the pressure parameters of the control panel 10 change, the screw 134 is rotated. The screw 134 drives the transmission block 133 and the adjusting block 132 to move. The adjusting block 132 compresses or loosens the spring 131, so that the pressure generated by the spring 131 on the constant pressure rod 8 can be adjusted, so that the compass head grinder 12 always maintains the same pressure parameters for friction detection on the top of the leather.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
