Description

Technical Field

[0001] The invention relates to the technical field of detection devices, in particular to a device for detecting the tensile properties of suede-like leather. Background Art

[0002] In the field of performance testing of suede, tensile strength is one of the important indicators to measure its quality.

[0003] At present, traditional tensile performance testing devices have many problems that need to be solved when testing imitation suede. On the one hand, since the surface of imitation suede has a fuzzy structure, the testing fixture has poor clamping effect on it during the testing process, and the imitation suede is prone to slipping, which not only affects the accuracy of the test results, but may also damage the imitation suede due to improper clamping pressure. On the other hand, during the testing process, the fuzz on the imitation suede is easy to fall off, and the scattered fuzz will fly around in the testing box, which not only brings difficulties to subsequent cleaning work, but also may affect the normal operation of the testing device. In addition, the existing testing devices are often unable to effectively handle the fuzz on the imitation suede during the testing process, making it difficult to ensure the stability and reliability of the test. Summary of the Invention

[0004] The purpose of the present invention is to provide a suede-like tensile performance testing device to solve the problems raised in the prior art.

[0005] To achieve the above object, the present invention provides the following technical solutions: A device for testing the tensile properties of imitation suede includes a testing box, a protective cover, a testing fixture, an electric field generator, and a cleaning device. There are two testing fixtures, which are symmetrically placed in the testing box. The testing box and the protective cover are rotatably connected, the testing fixture is connected to the testing box, and the testing fixture is connected to the electric field generator. The cleaning device is placed in the testing box, and the testing box and the cleaning device are connected.

[0006] The test box serves as the main installation base for the installation and positioning of other components. When the tensile test of the imitation suede begins, the worker opens the protective cover, then places the imitation suede on the test fixture, turns on the electric field generator, and the hair on the imitation suede is oriented under the action of the electric field excited by the electric field generator. The test fixture then clamps the imitation suede, which improves the clamping effect of the test fixture. During the tensile performance test of the test fixture, the hair falls off, and the cleaning device controls the direction of the hair falling to send the hair to the bottom of the test box, and then collects the hair centrally to prevent it from flying around, which would cause certain difficulties for subsequent cleaning.

[0007] Furthermore, the detection fixture includes a detection cylinder, a rotating motor, a connecting plate and a clamping cylinder. The detection cylinder and the detection box are tightly connected, the output end of the detection cylinder and the rotating motor are tightly connected, the output end of the rotating motor and the connecting plate are tightly connected, two clamping cylinders are provided on the connecting plate, the two clamping cylinders are symmetrically placed on the connecting plate, a clamping plate is provided on the clamping cylinder, and the clamping plate and the clamping cylinder are tightly connected.

[0008] When it is necessary to perform tensile testing on the imitation suede, the detection cylinder outputs outward to drive the rotating motor to move, the rotating motor moves to drive the connecting plate to move, the connecting plate moves to drive the clamping cylinder to move, the clamping cylinder moves to drive the clamping plate to move until the clamping plate can clamp the imitation suede in the working area, then the clamping cylinders symmetrically placed on the connecting plate output outward to drive the clamping plate to move, until the imitation suede is initially clamped and the clamping cylinder stops outputting, then the detection cylinder outputs inward to drive the rotating motor to move, the rotating motor moves to drive the connecting plate to move, The movement of the connecting plate drives the movement of the clamping cylinder, and the movement of the clamping cylinder drives the movement of the clamping plate, thereby stretching the imitation suede. Then, the clamping plate is used to detect whether the imitation suede produces relative sliding. When the imitation suede produces sliding, the friction force of the clamping plate on the imitation suede is increased by the clamping plate, and the output force of the clamping cylinder is adjusted at the same time, so that the pressure of the clamping plate on the imitation suede is gradually increased while increasing the pulling force on the imitation suede. By dynamically adjusting the pressure on the imitation suede, the degree of damage to the imitation suede due to excessive detection pressure during the detection process is greatly reduced.

[0009] Furthermore, the clamping plate is provided with a plurality of clamping cavities, and a clamping device is provided in the clamping cavity. The clamping device includes a moving block, a magnet, an induction coil and a reset spring. The moving block is slidably connected to the clamping cavity, the reset spring is placed in the induction coil, the reset spring is firmly connected to the clamping cavity, the end of the reset spring away from the clamping cavity is firmly connected to the magnet, the end of the magnet away from the reset spring is firmly connected to the moving block, and the induction coil is electrically connected to the clamping cylinder.

[0010] The clamping cavity is used as the main installation base for the installation and positioning of other components. The clamping device is used as the main detection device to detect whether the imitation suede needs to increase pressure. In the process of detecting the imitation suede, the imitation suede is clamped by the clamping plate. When the pulling force on the imitation suede gradually increases, the friction force required to control the imitation suede to be stationary increases. The friction force is provided to the imitation suede by the moving block. When the friction force required by the imitation suede gradually increases, the force of the imitation suede on the moving block increases, causing the moving block to move. The movement of the moving block increases the contact area between the moving block and the imitation suede, further increasing the magnitude of the friction force on the relative sliding of the imitation suede, and at the same time, the moving block The movement of the moving block drives the movement of the magnet, and the movement of the magnet generates an induced current in the induction coil. According to the signal of the generated induced current, the clamping cylinder is controlled to output the force, thereby increasing the pressure of the clamping plate on the suede, thereby realizing dynamic control of the pressure required to prevent the suede from sliding during the detection process. By increasing the contact area between the moving block and the suede to increase the friction force and gradually increasing the clamping pressure on the suede, the increase in contact area and the increase in pressure work simultaneously, preventing the suede from moving during the detection process from two directions, greatly alleviating the situation where the suede is damaged due to excessive pressure on the clamped suede during detection.

[0011] Furthermore, a DLC coating is provided on a side of the moving block that contacts the imitation suede, and the moving block is made of rubber material.

[0012] The DLC coating is provided to improve the friction effect of the moving block on the imitation suede. The moving block is provided with a rubber material so that the moving block can be squeezed and deformed in the clamping cavity. At the same time, the moving block in the contact part with the imitation suede can expand and deform fully to contact the imitation suede to improve the friction effect.

[0013] Furthermore, the clamping plate at the bottom end of the detection box is tightly connected to the electric field generator, and the clamping plate of the protective cover is provided with a mounting groove, which is located directly above the electric field generator.

[0014] By arranging an electric field generator on the clamping plate, before the imitation suede is clamped, the electric field can be excited by the electric field generator to control the direction of the hair on the imitation suede, so that the hair on the imitation suede in the clamping area of ​​the clamping plate is oriented neatly, thereby further improving the effect of the force on the imitation suede. After the arrangement is neat, the electric field generator is turned off to prevent the electric field generator from affecting the induction coil. The installation groove is provided so that the electric field generator can enter the installation groove during the clamping process, thereby preventing the electric field generator from being squeezed and damaged by the clamping plate during the clamping process.

[0015] Furthermore, a collecting chamber and a negative pressure hole are provided in the detection box, the collecting chamber and the negative pressure hole are connected, the negative pressure hole is used to provide negative pressure in the detection box, and the cleaning device is located above the negative pressure hole.

[0016] Negative pressure is provided by the provided negative pressure hole, and at the same time, the fluff in the detection box can be sucked into the negative pressure hole through the cleaning device and then sent to the collection chamber, preventing the fluff from being scattered in the detection box and difficult to clean.

[0017] Furthermore, the cleaning device includes a support column, a mounting base, a support plate and a corona needle. The support column and the detection box are tightly connected, the support column and the mounting base are tightly connected, the mounting base and the support plate are tightly connected, there are two support plates, and the two support plates are located directly below the detection fixture. A fixed motor and a mounting box are provided on the support plate. A fixed mounting cavity is also provided on the support plate. The fixed motor is placed in the fixed mounting cavity. The fixed motor and the fixed mounting cavity are tightly connected. The output end of the fixed motor and the mounting box are tightly connected. There are several corona needles, and several corona needles are placed in the mounting box. Several corona needles and the mounting box are tightly connected.

[0018] The support column is used as the main installation foundation to support other components. The installation base is lifted by the support column so that the installation base can be installed directly above the negative pressure hole. At the beginning of the tensile test, a small power is output to the corona needle so that the electric field formed by the corona needle covers the vicinity of the installation box, and the fuzz is repelled by the electric field to prevent it from falling on the installation box. When the test is completed, the output power of the corona needle is increased so that the electric field can cover the suede. Then, the fixed motor in the fixed installation cavity outputs a torque to drive the installation box to rotate, and the rotation of the installation box drives the corona needle in the installation box The rotation of the electric field repels the fluff on the imitation suede, causing the fluff on the imitation suede to fall off. At the same time, the rotating electric field gradually repels the fluff to the bottom of the detection box, and then the fluff is adsorbed through the negative pressure hole and collected in the collection chamber. After processing the fluff on one side of the imitation suede, the motor outputs a rotational torque to drive the connecting plate to rotate, thereby rotating the clamping cylinder. The rotation of the clamping cylinder drives the clamping plate connected to the clamping cylinder to rotate, thereby rotating the imitation suede clamped by the clamping plate, and then the fluff on the other side of the imitation suede is cleaned.

[0019] Furthermore, the installation box is provided with a plurality of electrostatic through holes.

[0020] The electrostatic through hole is provided so that the electric field formed by the corona needle can pass through the electrostatic through hole and act on the outside of the installation box.

[0021] Compared with the prior art, the present invention has the following beneficial effects: 1. By exciting the electric field through the electric field generator, the hairs on the imitation suede can be oriented and arranged, so that the hairs in the clamping area of ​​the clamping plate are oriented neatly, thereby significantly improving the clamping effect of the detection fixture on the imitation suede.

[0022] 2. The moving block in the clamping device moves when the friction required by the suede increases. This not only increases the contact area with the suede to increase the friction, but also generates an induced current in the induction coil through the movement of the magnet. This signal controls the clamping cylinder to adjust the output force, thereby dynamically adjusting the clamping pressure. The clamping force is gradually increased while the pulling force is increased, which greatly reduces the damage of the suede caused by excessive test pressure and effectively ensures the accuracy of the test results.

[0023] 3. After the test is completed, the corona needle in the cleaning device drives the installation box to rotate through a fixed motor, so that the rotating electric field formed by the corona needle can repel the fluff on the imitation suede and gradually guide the fluff to the bottom of the test box. Then, with the help of the cooperation between the negative pressure hole and the collection chamber, the fluff is concentratedly adsorbed and collected, preventing the fluff from flying around in the test box, solving the problem of subsequent cleaning difficulties, keeping the test environment clean, and reducing the adverse effects of the fluff on the test device.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example: Figures 1-8 As shown, the present invention provides a technical solution for a suede-like tensile performance testing device, the testing device comprising a testing box 1, a protective cover 2, a testing fixture 3, an electric field generator 4 and a cleaning device 5. There are two testing fixtures 3, which are symmetrically placed in the testing box 1. The testing box 1 and the protective cover 2 are rotatably connected, the testing fixture 3 and the testing box 1 are connected, the testing fixture 3 and the electric field generator 4 are connected, the cleaning device 5 is placed in the testing box 1, and the testing box 1 and the cleaning device 5 are connected.

[0028] The testing box 1 is used as the main installation base for the installation and positioning of other components. When the tensile test of the imitation suede begins, the worker opens the protective cover 2, and then places the imitation suede on the testing fixture 3, turns on the electric field generator 4, and the fluff on the imitation suede is oriented under the action of the electric field excited by the electric field generator 4, and then the testing fixture 3 clamps the imitation suede, which improves the clamping effect of the testing fixture 3. In the process of the tensile performance test of the testing fixture 3, the fluff falls off, and the cleaning device 5 controls the direction of the fluff falling to send the fluff to the bottom of the testing box 1, and then the fluff is collected centrally to prevent the fluff from flying around, which brings certain difficulties to the subsequent cleaning.

[0029] like Figure 2-Figure 3 As shown, the detection fixture 3 includes a detection cylinder 31, a rotating motor 32, a connecting plate 33 and a clamping cylinder 34. The detection cylinder 31 is tightly connected to the detection box 1, the output end of the detection cylinder 31 is tightly connected to the rotating motor 32, the output end of the rotating motor 32 is tightly connected to the connecting plate 33, two clamping cylinders 34 are provided on the connecting plate 33, the two clamping cylinders 34 are symmetrically placed on the connecting plate 33, a clamping plate 35 is provided on the clamping cylinder 34, and the clamping plate 35 and the clamping cylinder 34 are tightly connected.

[0030] When it is necessary to perform a tensile test on the imitation suede, the detection cylinder 31 outputs outward to drive the rotating motor 32 to move, the rotating motor 32 moves to drive the connecting plate 33 to move, the connecting plate 33 moves to drive the clamping cylinder 34 to move, the clamping cylinder 34 moves to drive the clamping plate 35 to move, until the clamping plate 35 can clamp the imitation suede in the working area, then the clamping cylinders 34 symmetrically placed on the connecting plate 33 output outward to drive the clamping plate 35 to move, until the imitation suede is initially clamped and the clamping cylinder 34 stops outputting, then the detection cylinder 31 outputs inward to drive the rotating motor 32 to move, the rotating motor 32 moves to drive The connecting plate 33 moves, and the movement of the connecting plate 33 drives the clamping cylinder 34 to move, and the movement of the clamping cylinder 34 drives the clamping plate 35 to move, thereby stretching the imitation suede. Then, the clamping plate 35 is used to detect whether the imitation suede produces relative sliding. When the imitation suede produces sliding, the friction of the clamping plate 35 on the imitation suede is increased by the clamping plate 35, and the output force of the clamping cylinder 34 is adjusted at the same time, so that the pressure of the clamping plate 35 on the imitation suede is gradually increased while increasing the pulling force on the imitation suede. By dynamically adjusting the pressure on the imitation suede, the degree of damage to the imitation suede due to excessive detection pressure during the detection process is greatly reduced.

[0031] like Figure 3 、 Figure 5 、 Figure 6 and Figure 7 As shown, the clamping plate 35 is provided with a plurality of clamping cavities 351, and the clamping cavity 351 is provided with a clamping device 352, and the clamping device 352 includes a moving block 3521, a magnet 3522, an induction coil 3523 and a return spring 3524. The moving block 3521 is slidably connected to the clamping cavity 351, and the return spring 3524 is placed in the induction coil 3523. The return spring 3524 is firmly connected to the clamping cavity 351, and the end of the return spring 3524 away from the clamping cavity 351 is firmly connected to the magnet 3522, and the end of the magnet 3522 away from the return spring 3524 is firmly connected to the moving block 3521, and the induction coil 3523 is electrically connected to the clamping cylinder 34.

[0032] The clamping cavity 351 is used as the main installation base for the installation and positioning of other components. The clamping device 352 is used as the main detection device to detect whether the imitation suede needs to increase pressure. In the process of detecting the imitation suede, the imitation suede is clamped by the clamping plate 35. When the pulling force on the imitation suede gradually increases, the friction force required to control the imitation suede to be stationary increases. The friction force is provided to the imitation suede by the moving block 3521. When the friction force required by the imitation suede gradually increases, the force of the imitation suede on the moving block 3521 increases, causing the moving block 3521 to move. The movement of the moving block 3521 increases the contact area between the moving block 3521 and the imitation suede, further increasing the magnitude of the friction force causing the imitation suede to slide relative to each other. When the movable block 3521 moves, the magnet 3522 moves. The movement of the magnet 3522 generates an induced current in the induction coil 3523. According to the signal of the induced current, the clamping cylinder 34 is controlled to output a force, thereby increasing the pressure of the clamping plate 35 on the suede, thereby realizing dynamic control of the pressure required to prevent the suede from sliding during the detection process. By increasing the contact area between the movable block 3521 and the suede to increase the friction force and gradually increasing the clamping pressure on the suede, the increase in contact area and the increase in pressure work at the same time, preventing the suede from moving during the detection process from two directions, greatly alleviating the situation in which the suede is damaged due to excessive pressure on the clamped suede during the detection.

[0033] like Figure 6 As shown, the side of the moving block 3521 that contacts the imitation suede is provided with a DLC coating, and the moving block 3521 is made of rubber material.

[0034] The DLC coating is provided to improve the friction effect of the moving block 3521 on the imitation suede. The moving block 3521 is made of rubber material so that the moving block 3521 can be squeezed and deformed in the clamping cavity 351. At the same time, the moving block 3521 in the contact part with the imitation suede can expand and deform fully to contact the imitation suede to improve the friction effect.

[0035] like Figure 3 As shown, the clamping plate 35 at the bottom end of the detection box 1 is tightly connected to the electric field generator 4 , and a mounting groove 353 is provided on the clamping plate 35 of the protective cover 2 , and the mounting groove 353 is located directly above the electric field generator 4 .

[0036] By providing an electric field generator 4 on the clamping plate 35, before the imitation suede is clamped, the electric field can be excited by the electric field generator 4 to control the direction of the hair on the imitation suede, so that the hair on the imitation suede in the clamping area of ​​the clamping plate 35 is oriented neatly, thereby further improving the effect of the force on the imitation suede. After the arrangement is neat, the electric field generator 4 is turned off to prevent the electric field generator 4 from affecting the induction coil 3523. The installation groove 353 is provided so that the electric field generator 4 can enter the installation groove 353 during the clamping process, thereby preventing the electric field generator 4 from being squeezed and damaged by the clamping plate 35 during the clamping process.

[0037] like Figure 4 As shown, a collecting chamber 11 and a negative pressure hole 12 are provided in the detection box 1 . The collecting chamber 11 and the negative pressure hole 12 are connected. The negative pressure hole 12 is used to provide negative pressure in the detection box 1 . The cleaning device 5 is located above the negative pressure hole 12 .

[0038] Negative pressure is provided by the negative pressure hole 12 , and the cleaning device 5 allows the fluff in the detection box 1 to be sucked into the negative pressure hole 12 and then sent to the collection chamber 11 , preventing the fluff from being scattered in the detection box 1 and difficult to clean.

[0039] like Figure 4 and Figure 8 As shown, the cleaning device 5 includes a support column 51, a mounting base 52, a support plate 53 and a corona needle 56. The support column 51 is tightly connected to the detection box 1, the support column 51 is tightly connected to the mounting base 52, the mounting base 52 and the support plate 53 are tightly connected, there are two support plates 53, and the two support plates 53 are located directly below the detection fixture 3. A fixed motor 54 and a mounting box 55 are provided on the support plate 53. A fixed mounting cavity 531 is also provided on the support plate 53. The fixed motor 54 is placed in the fixed mounting cavity 531. The fixed motor 54 is tightly connected to the fixed mounting cavity 531. The output end of the fixed motor 54 is tightly connected to the mounting box 55. There are several corona needles 56. Several corona needles 56 are placed in the mounting box 55, and several corona needles 56 are tightly connected to the mounting box 55.

[0040] The support column 51 is used as the main installation base to support other components. The installation base plate 52 is lifted by the support column 51 so that the installation base plate 52 can be installed just above the negative pressure hole 12. When the tensile test begins, a smaller power is output to the corona needle 56 so that the electric field formed by the corona needle 56 covers the vicinity of the installation box 55, and the fluff is repelled by the electric field to prevent the fluff from falling on the installation box 55. When the test is completed, the output power of the corona needle 56 is increased so that the electric field can cover the imitation suede, and then the fixed motor 54 in the fixed installation cavity 531 outputs a torque to drive the installation box 55 to rotate, and the installation box 55 rotates to drive the installation box 55 inside. The corona needle 56 rotates, thereby causing the electric field formed by the corona needle 56 to rotate. The rotation of the electric field repels the fluff on the imitation suede, causing the fluff on the imitation suede to fall off. At the same time, the rotating electric field gradually repels the fluff to the bottom of the detection box 1, and then the fluff is adsorbed through the negative pressure hole 12 and collected in the collection chamber 11. After processing the fluff on one side of the imitation suede, the rotational torque output by the rotating motor 32 drives the connecting plate 33 to rotate, thereby rotating the clamping cylinder 34. The rotation of the clamping cylinder 34 drives the clamping plate 35 connected to the clamping cylinder 34 to rotate, thereby rotating the imitation suede clamped by the clamping plate 35, and then the fluff on the other side of the imitation suede is cleaned.

[0041] like Figure 8 As shown, the installation box 55 is provided with a plurality of electrostatic through holes 551 .

[0042] The electrostatic through hole 551 is provided so that the electric field formed by the corona needle 56 can pass through the electrostatic through hole 551 and act on the outside of the installation box 55 .

[0043] The working principle of the present invention is as follows: the test box 1 is used as the main installation base for the installation and positioning of other components. When the tensile test of the imitation suede begins, the worker opens the protective cover 2, then places the imitation suede on the test fixture 3, turns on the electric field generator 4, and the hairs on the imitation suede are oriented under the action of the electric field excited by the electric field generator 4. Then the test fixture 3 clamps the imitation suede. During the test of the imitation suede, the imitation suede is clamped by the clamping plate 35. The imitation suede is clamped. When the pulling force on the imitation suede gradually increases, the friction force required to control the imitation suede to be stationary increases. The friction force is provided to the imitation suede by the moving block 3521. When the friction force required by the imitation suede gradually increases, the force exerted by the imitation suede on the moving block 3521 increases, causing the moving block 3521 to move. The movement of the moving block 3521 increases the contact area between the moving block 3521 and the imitation suede, further increasing the relative sliding of the imitation suede. The size of the friction force of the movement is increased. At the same time, the movement of the moving block 3521 drives the movement of the magnet 3522. The movement of the magnet 3522 generates an induced current in the induction coil 3523. According to the signal of the generated induced current, the clamping cylinder 34 is controlled to output the force, thereby increasing the pressure of the clamping plate 35 on the imitation suede, thereby realizing dynamic control of the pressure required to prevent the imitation suede from sliding during the detection process. By increasing the contact area between the moving block 3521 and the imitation suede to increase the friction force and gradually increasing the clamping pressure on the imitation suede, the situation in which the imitation suede is damaged due to excessive pressure on the clamped imitation suede during the detection is greatly alleviated, and the clamping effect of the detection fixture 3 is improved. During the tensile performance test of the detection fixture 3, fluff falls off. The cleaning device 5 controls the direction of the fluff falling to send the fluff to the bottom of the detection box 1, and then collects the fluff in a centralized manner to prevent the fluff from flying around and causing certain difficulties for subsequent cleaning.

[0044] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention.
