Description

Technical Field

[0001] The present invention belongs to the technical field of textile quality inspection, and particularly relates to a textile spinning product elasticity testing machine. Background Art

[0002] Textile fabrics are usually used to cut into various products such as clothes. In order to make textile fabrics better meet people's wearing needs, textile fabrics need to maintain a specific elasticity, so as to have a certain deformation space to better adapt to different human body shapes. In view of this, in the production process of textile fabrics, it is often necessary to detect the elasticity of textile fabrics to prevent the elasticity of textile fabrics from being lower than the standard value. For example, a textile spinning product elasticity testing machine involved in the existing public patent (application number: CN201920417362.9) includes a guide rail vertically fixed between a bottom plate and a cross beam, a guide rod slidably connected to the guide rail and equipped with a pressure sensor, a textile fabric fixing mechanism fixedly connected to the bottom plate and located at a position corresponding to the guide rod, and a punch assembled at one end of the guide rod close to the textile fabric fixing mechanism.

[0003] However, the above-mentioned elasticity testing machine has certain defects in the actual testing process. First, it can only detect one fabric sample at a time, and the detection efficiency is relatively low. Second, after the test is completed, the staff can only analyze and judge whether the elasticity of each sample is qualified based on the measured data one by one, and it is impossible for the staff to understand the test conditions of each sample in an intuitive and fast way. In addition, during the actual use of the above-mentioned testing machine, the machine cannot be effectively stabilized, resulting in easy deviation due to accidental collision during the detection, and thus the test process is easily interfered.

[0004] Therefore, we propose a textile spinning product elasticity testing machine to solve the above problems. Summary of the Invention

[0007] In the above-mentioned textile spinning product elasticity testing machine, the electrical signal feedback mechanism consists of a feedback cavity, an electromagnetic block, a permanent magnet block and a trigger switch. The feedback cavity is opened on the base, and the electromagnetic block and the trigger switch are both fixedly installed in the feedback cavity. The electromagnetic block is fixedly connected to the permanent magnet block through a reset spring, and the permanent magnet block is slidably connected to the feedback cavity. A pressure block is fixedly arranged on the permanent magnet block, and the pressure block and the trigger switch are arranged opposite to each other. The electromagnetic block is electrically connected to the corresponding pressure sensor through a current amplification module, and the trigger switch is electrically connected to the corresponding prompt light.

[0008] In the above-mentioned textile spinning product elasticity testing machine, the joint control mechanism includes a pulley assembly, a bevel gear assembly and a control shaft. A joint control box is fixedly arranged on the support frame, and each threaded sleeve is arranged through the joint control box. The threaded sleeves in the joint control box are connected by the pulley assembly. The control shaft is rotatably arranged in the joint control box, and the control shaft is connected to one of the threaded sleeves by the bevel gear assembly.

[0009] In the above-mentioned textile spinning elasticity testing machine, the three threaded sleeves are distributed in a triangle, and the thread lead angle of the threaded sleeve is smaller than the equivalent friction angle. One end of the control shaft passes through the joint control box and is fixedly connected to the handle.

[0010] In the above-mentioned textile spinning product elasticity testing machine, the adsorption and fixing mechanism is composed of an air pump, an air guide cavity and a plurality of suction cups, the air pump is installed on the base, the air guide cavity is opened on the base, and the input end of the air pump is connected with the air guide cavity, each of the suction cups is fixedly arranged on the lower side of the base, and each of the suction cups is connected with the air guide cavity.

[0011] In the above-mentioned textile yarn elasticity testing machine, an air inlet pipe communicating with the air guide cavity is fixedly arranged on the base, and an electromagnetic valve is installed on the air inlet pipe.

[0012] In the above-mentioned textile spinning elastic testing machine, cylinders are fixedly arranged on both sides of the base, and a limiting block is fixedly connected to the output end of the cylinder. A pointer is fixedly arranged on the limiting block, and a scale line matching the pointer is arranged on the support frame.

[0013] In the above-mentioned textile spinning elastic testing machine, a threaded block is fixedly connected to the lower end of the fabric fixing sleeve, and a threaded groove matching the threaded block is formed on the base.

[0015] Compared with the existing technology, the advantages of a textile spinning elastic testing machine are as follows:

[0016] 1. The cooperation between the linkage mechanism and the pressing plate can control multiple detection heads to move downward synchronously to detect each sample simultaneously, greatly improving the efficiency of the textile cloth testing work. And through the set electrical signal feedback mechanism, based on the elastic condition of the corresponding sample detected by the detection head, the corresponding indicator light can be kept off or on. Furthermore, through the on-off state of the corresponding indicator light, it can be directly judged whether the elasticity of the corresponding sample meets the requirements.

[0017] 2. The three threaded sleeves in the linkage mechanism are distributed in a triangle. The triangular distribution has good stability, and it can make the belt on the pulley assembly better receive force for transmission. In addition, this layout can make the forces exerted by the three threaded push rods on the pressing plate more uniform and balanced, reducing the inclination or instability of the pressing plate caused by uneven force, ensuring the smooth progress of the downward pressing action. Moreover, this distribution method is beneficial to the transmission and dispersion of force, and can transmit the driving force more evenly to each part of the pressing plate, making the overall force on the pressing plate more consistent, avoiding the situation of local overstress or understress, so as to ensure the reliability of the test results.

[0018] 3. The setting of the adsorption and fixation mechanism can make the testing machine effectively suck and fix on the placed workbench surface to ensure the stability of the testing machine during detection. Through the cooperation of the set threaded block and threaded groove, it is convenient to disassemble and replace the fabric fixing sleeve in the later stage. And through the set label blocks, each indicator light can be numbered to facilitate better correspondence with the corresponding sample fabric. Description of the Drawings

Specific embodiments

[0025] The following embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0026] As Figures 1-5 shown, an elastic testing machine for textile spinning products includes a base 1, a support frame 2 is fixedly arranged on the base 1, three threaded sleeves 3 are rotatably arranged on the support frame 2, and threaded push rods 4 are threadedly connected to all three threaded sleeves 3. The lower ends of the three threaded push rods 4 are fixedly connected together to form a pressing plate 5. A plurality of pressure sensors 6 are fixedly installed on the lower end surface of the pressing plate 5, and detection heads 7 are fixedly installed on the pressure sensors 6. A plurality of fabric fixing sleeves 8 are fixedly arranged on the base 1, and each fabric fixing sleeve 8 corresponds to each detection head 7 one by one. The lower end of the fabric fixing sleeve 8 is fixedly connected with a threaded block 23, and a threaded groove 24 matching the threaded block 23 is formed on the base 1. The cooperation between the threaded block 23 and the threaded groove 24 facilitates the disassembly and replacement of the fabric fixing sleeve 8;

[0027] A plurality of indicator lights 9 are fixedly mounted on the base 1, and the indicator lights 9 are electrically connected to the corresponding pressure sensors 6 through the electrical signal feedback mechanism 10. A plurality of label blocks 25 are fixedly arranged on the base 1, and each label block 25 corresponds to each indicator light 9 one by one. The arrangement of the label blocks 25 facilitates the pasting of label numbers, so that the indicator lights 9 better correspond to the sample fabric.

[0028] The electric signal feedback mechanism 10 consists of a feedback chamber 101, an electromagnetic block 102, a permanent magnet block 103 and a trigger switch 104. The feedback chamber 101 is opened on the base 1, and the electromagnetic block 102 and the trigger switch 104 are both fixedly installed in the feedback chamber 101. The electromagnetic block 102 is fixedly connected to the permanent magnet block 103 through a reset spring 13, and the permanent magnet block 103 is slidably connected to the feedback chamber 101. A pressing block 14 is fixedly arranged on the permanent magnet block 103, and the pressing block 14 and the trigger switch 104 are arranged opposite to each other. The electromagnetic block 102 is electrically connected to the corresponding pressure sensor 6 through a current amplification module, and the trigger switch 104 is electrically connected to the corresponding warning light 9. The set electromagnetic block 102 can control the corresponding trigger switch 104 to open and close based on the change degree of the current signal of the corresponding pressure sensor 6, thereby controlling the corresponding warning light 9 to turn on and off;

[0029] The support frame 2 is provided with a joint control mechanism 11 matched with each threaded sleeve 3, and the joint control mechanism 11 includes a pulley assembly 111, a bevel gear assembly 112 and a control shaft 113. A joint control box 15 is fixedly provided on the support frame 2, and each threaded sleeve 3 is arranged through the joint control box 15. The threaded sleeves 3 in the joint control box 15 are connected by the pulley assembly 111. The control shaft 113 is rotatably arranged in the joint control box 15, and the control shaft 113 is connected to one of the threaded sleeves 3 by the bevel gear assembly 112. Through the transmission cooperation of the bevel gear assembly 112 and the pulley assembly 111, the staff can control the synchronous rotation of the three threaded sleeves 3 through the control shaft 113, which greatly facilitates the operation mode, and does not require additional electric energy equipment to drive, which greatly saves the device cost;

[0030] The three threaded sleeves 3 are distributed in a triangle, and the lead angle of the threads of the threaded sleeve 3 is less than the equivalent friction angle. One end of the control shaft 113 passes through the control box 15 and is fixedly connected with a handle 16. The three threaded sleeves 3 are distributed in a triangle. The triangular distribution has good stability and can make the belt on the pulley assembly 111 better receive force for transmission. In addition, this layout can make the forces exerted by the three threaded push rods 4 on the pressing plate 5 more uniform and balanced, reducing the inclination or instability of the pressing plate 5 caused by uneven force, ensuring the smooth progress of the pressing action. Moreover, this distribution method is conducive to the transmission and dispersion of force, and can transmit the driving force more evenly to each part of the pressing plate 5, making the overall force on the pressing plate 5 more consistent, avoiding the situation of excessive or insufficient force in some parts, so as to ensure the reliability of the test results. The design of the lead angle of the threads of the threaded sleeve 3 can achieve self-locking between the threaded sleeve 3 and the threaded push rod 4, avoiding the tediousness of manual locking. The setting of the handle 16 facilitates the staff to control the rotation of the control shaft 113;

[0031] An adsorption and fixing mechanism 12 is arranged on the base 1. The adsorption and fixing mechanism 12 is composed of an air extraction pump 121, an air guide cavity 122 and a plurality of suction cups 123. The air extraction pump 121 is installed on the base 1, the air guide cavity 122 is opened on the base 1, and the input end of the air extraction pump 121 is communicated with the air guide cavity 122. Each suction cup 123 is fixedly arranged on the lower side of the base 1, and each suction cup 123 is communicated with the air guide cavity 122. By setting the air extraction pump 121, it can cooperate with the air guide cavity 122 to suck the air in each suction cup 123, so that each suction cup 123 quickly sucks and adheres to the corresponding workbench surface, thereby ensuring the stability of the device placement. An air inlet pipe 17 communicated with the air guide cavity 122 is fixedly arranged on the base 1, and a solenoid valve 18 is installed on the air inlet pipe 17. The setting of the solenoid valve 18 facilitates the subsequent control of the opening of the air inlet pipe 17, so that the outside air enters each suction cup 123 to relieve the negative pressure state of the suction cup 123;

[0032] Cylinders 19 are fixedly arranged on both sides of the base 1, the output ends of the cylinders 19 are fixedly connected with limit blocks 20, pointers 21 are fixedly arranged on the limit blocks 20, and scale lines 22 matched with the pointers 21 are arranged on the support frame 2. The cylinders 19 can control the lifting of the limit blocks 20. The cooperation of the pointers 21 and the scale lines 22 can locate the positions of the limit blocks 20, and then the downward movement position of the detection head 7 can be limited as needed, and then the downward pressure can be controlled according to the test pressure required for different types of sample fabrics.

[0033] The operating principle of the present invention is described as follows:

[0034] During the test, each cut sample fabric of the same batch is sleeved on the corresponding fabric fixing sleeve 8 and locked tightly with a hose clamp. At the same time, each sample fabric is numbered in sequence with a marker pen, such as No. 1, No. 2, No. 3. Meanwhile, a label sticker corresponding to the sample fabric is pasted on the label block 25. Then, according to the detection force required for this batch of sample fabrics, the position of the limit block 20 is adjusted. Specifically, the cylinder 19 is used to control the upward movement of the limit block 20. When the pointer 21 indicates the required scale, the cylinder 19 is turned off. Then, the downward movement position of the detection head 7 is limited by the position of the limit block 20 to control the downward pressure. Subsequently, the rotary handle 16 is rotated. The rotary handle 16 will drive the control shaft 113 to rotate. Under the transmission and cooperation of the bevel gear assembly 112, one of the threaded sleeves 3 will rotate synchronously. Under the transmission and cooperation of the pulley assembly 111, the three threaded sleeves 3 will rotate synchronously. As a result, the three threaded push rods 4 synchronously control the downward movement of the pressure plate 5. The pressure plate 5 will drive each detection head 7 to move downward, so that each detection head 7 presses the corresponding sample fabric. When the pressure plate 5 abuts against the limit block 20, stop rotating the rotary handle 16;

[0035] When the sample fabric is squeezed, a reaction force will be generated, which acts on the corresponding pressure sensor 6 through the detection head 7, causing the corresponding current signal change of the pressure sensor 6. Specifically, when the detection head 7 squeezes the sample fabric with low elasticity, since this kind of fabric is difficult to stretch and deform, it will generate a large reaction force on the pressure sensor 6 when being squeezed. The pressure sensor 6 will sense a large pressure feedback, and then generate a large current signal. For the fabric with high elasticity, when being squeezed, it will be relatively easy to stretch and deform, thus buffering part of the pressure. At this time, the pressure sensed by the pressure sensor 6 is relatively small, and then a small current signal is generated;

[0036] When the detection head 7 squeezes the sample fabric with low elasticity and does not meet the requirements, the corresponding pressure sensor 6 will generate a large current signal. After being amplified by the current amplification module, the current flowing into the corresponding electromagnet 102 increases in proportion. Then, the magnetism of the electromagnet 102 will increase, causing the electromagnet 102 to repel the corresponding permanent magnet 103, so that the pressure block 14 on the permanent magnet 103 presses the corresponding trigger switch 104, and then the corresponding indicator light 9 lights up. When the detection head 7 squeezes the sample fabric with qualified elasticity, since the sample fabric is large, the electrical signal generated by the pressure sensor 6 is small. Similarly, the current magnitude fed back to the electromagnet 102 is small. Then, the electromagnet 102 cannot effectively repel the corresponding permanent magnet 103 to squeeze the trigger switch 104, so that the corresponding indicator light 9 lights up. Then, after the detection, the staff can intuitively judge whether the elasticity of the sample fabric is qualified according to the state of the indicator light 9 corresponding to the sample fabric;

[0037] When this testing machine is placed on the workbench, the air in each suction cup 123 is sucked by the air extraction pump 121, so that the suction cup 123 is suctioned to the workbench, thereby ensuring the stability of the placement of the entire device. And when it is necessary to move this testing machine, the solenoid valve 18 is activated, so that the outside air enters each suction cup 123 through the air inlet pipe 17, releasing the negative pressure state of the suction cup 123.

[0038] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
