Description

Technical Field

[0001] The present invention is an adjustable weather resistance testing device, belonging to the technical field of product quality testing. Background Art

[0002] Weather resistance tests are designed to examine the tolerance of materials to various factors such as climate and are key indicators for measuring material durability. Under the action of factors such as light and corrosion, the deterioration processes of the physical, chemical, and mechanical properties of materials are accelerated. As a basic material widely used in many fields such as textiles, it is particularly important to control the ex-factory quality of wire rods. For this reason, weather resistance tests are usually carried out on wire rods with the help of weather resistance testing equipment.

[0003] Before using the weather resistance testing equipment, to comprehensively evaluate the applicability of wire rods under different environmental factors, multiple wire rod samples are selected and immersed in liquid media containing different substances respectively. Subsequently, through multiple fixture toolings, these multiple wire rod samples soaked in different liquid media are installed inside the equipment. The light generator inside the equipment can simulate sunlight and irradiate the installed multiple wire rods simultaneously to carry out adjustable weather resistance tests. After the test, the multiple wire rods are taken out and tensile tests are carried out on each of them one by one, and analysis and calculation are carried out based on the obtained tensile data to determine the weather resistance of the wire rods.

[0004] However, the current operation method of carrying out tensile tests on multiple wire rods after weather resistance tests one by one has obvious drawbacks. On the one hand, wire rod loss is easily caused during the tensile operation process, greatly increasing the probability of data acquisition errors in the test; on the other hand, this operation process takes a long time and has a large labor intensity, resulting in low work efficiency, and thus having an adverse impact on the accuracy of the weather resistance test results.

The two T-shaped rods 75 are used in cooperation to connect the third plates 73 and the second plates 72. Two collectors 77 located on the outer sides of the rod portions of the two T-shaped rods 75 are symmetrically arranged on the right ends of the third plates 73.

[0021] Before use, first select liquid media of different substances, and then immerse multiple wires to be detected into different test liquid media respectively, so as to perform adjustable weather resistance test operations on the wires subsequently. Then take out the wires to be detected, then open the cover plate 3, and then pull up the second movable plate 81, so that the second pressing block 83, the third rod 811, the third guide plate 812 and the second positioning column 813 move upward, so that the second positioning column 813 is separated from the second positioning hole 824 and the second pressing block 83 is separated from the second clamping groove. At the same time, when the third guide plate 812 moves upward, it will compress the fourth elastic member 823, causing the fourth elastic member 823 to generate an elastic force. Then rotate the second movable plate 81, so that the second clamping groove is completely exposed. Then place one end of the wire to be tested into the second clamping groove, then turn the second movable plate 81 back to its original position, then insert the second positioning column 813 into the second empty hole, and release the second movable plate 81. Then, under the elastic force of the fourth elastic member 823, the third guide plate 812 and the third rod 811 move downward along the second mounting hole 822, so that the second movable plate 81 moves downward, so that the second pressing block 83 moves downward along the second clamping groove, and then clamp one end of the wire to be tested; Then, the wire to be tested is orderly wound around the outer end of the second column 82 along the second spiral groove 831, and then the other end of the wire to be tested is orderly wound around the outer end of the first column 62 along the first spiral groove 631. Then, the first movable plate 61 is pulled upward, so that the first pressing block 63, the first positioning post 611, the second guide plate 612 and the second rod 613 move upward, so that the first positioning post 611 is separated from the first positioning hole 621 and the first pressing block 63 is separated from the first clamping groove. At the same time, when the second guide plate 612 moves upward, it will compress the second elastic member 622, causing the second elastic member 622 to generate an elastic force. Then, the first movable plate 61 is rotated, so that the first clamping groove is completely exposed, and then the other end of the wire to be tested is placed into the first clamping groove; Then, the first movable plate 61 is rotated back to its original position, and the first positioning post 611 is inserted into the first positioning hole 621. Then, the first movable plate 61 is released. Then, under the elastic force of the second elastic member 622, the second guide plate 612 and the second rod 613 move downward along the first mounting hole 623, so that the first movable plate 61 moves downward, so that the first pressing block 63 moves downward along the first clamping groove, so as to clamp the other end of the wire to be tested, realizing the winding installation of the wire to be tested, effectively reducing the probability of damage at the clamping point position of the wire during the test, effectively reducing the probability of errors in the data collected during the test, and effectively ensuring the accuracy of the weather resistance test result and the test effect; In the same steps as above, multiple wires to be tested are successively wound and installed into the housing 2, and then the cover plate 3 is closed to make the internal space of the housing 2 in a sealed state. Then, the light generator 5 is started to simulate sunlight to irradiate the multiple wound wires, and then a weather resistance test is carried out on the multiple wires. When the multiple wires are irradiated for a predetermined time, the electric push rod 71 is started to drive the push plate 7 to move to the right, so that the multiple function grooves 74 move synchronously to the right; Make the inclined surface of the function groove 74 move relative to the corresponding third plate 73, so that the third plate 73 and the two collectors 77 move synchronously to the right, so as to compress the two third elastic members 76 synchronously. Then, the two third elastic members 76 will exert a thrust on the corresponding second plate 72, so that the corresponding rotating shaft 84 rotates, and then the corresponding second column 82 rotates, so as to apply a tensile force to the wire after the weather resistance test. At the same time, the collector 77 collects the thrust data applied by the third elastic member 76 in real time. When the wire breaks, the data collected by the collector 77 at this time is the test data of the wire after the weather resistance test, and the test data can be analyzed and calculated to determine the weather resistance of the wire; It is possible to directly perform synchronous tensile operations on multiple wires after weathering tests, effectively reducing the probability of wire loss caused by operations such as picking up and placing the wires after weathering tests, effectively reducing the probability of errors in the data collected during the test, effectively reducing the operation time and labor intensity, improving work efficiency, and effectively ensuring the accuracy of the weather resistance test results.

[0022] Due to the flexibility and deformability of the wires, different degrees of deformation will occur in multiple wires during the test. When using two third elastic members 76 and the second plate 72 to rotate the rotating shaft 84 and the second column 82 to wind the wires, and when the wires are in a straightened state, continue to rotate the second column 82 to perform tensile operations on the wires. If a certain wire breaks, it means that the detection of this wire is completed, and the electric push rod 71 is used to make the push plate 7 continue to move to the right to perform tensile operations on other wires, realizing effective tensile operations on multiple wires, effectively reducing the probability of errors in the tensile data of some wires due to the different deformations of multiple wires, and effectively ensuring the accuracy and quality of the weather resistance test results.

[0023] Embodiment 2: In the weather resistance test process, with the coordinated operation of a series of components such as the second movable plate 81, the second pressing block 83, the third rod 811, the third guide plate 812, the second positioning column 813, the second clamping groove, the second spiral groove 831, the first movable plate 61, the first pressing block 63, the first positioning column 611, the second guide plate 612, the second rod 613, the first clamping groove, and the first spiral groove 631, the two ends of the wire to be tested can be orderly wound around the outer ends of the first column 62 and the second column 82 respectively. This design greatly reduces the possibility of damage to the wire clamping points during the test, providing a basic guarantee for the accuracy of subsequent tests.

[0024] After the preliminary preparation is completed, components such as the electric push rod 71, the push plate 7, multiple functional grooves 74, multiple third plates 73, multiple third elastic members 76, and multiple second plates 72 can be used to simultaneously carry out tensile tests on multiple wires after weathering tests. However, during the synchronous tensile operation of multiple wires, the situation of partial wire breakage often occurs. Due to the inertia of the tensile movement, the broken wires will swing randomly and are extremely likely to come into contact with other wires that are still undergoing tensile tests. This contact interference greatly increases the probability of errors in the data collected during the test of other wires, seriously affecting the accuracy and reliability of the detection results.

[0025] To solve the above problems, as Figures 1 - 5As shown in the figure, the auxiliary plate 44 is installed between the first plate 6 and the fourth plate 8, and the upper end surfaces of the auxiliary plate 44, the first plate 6 and the fourth plate 8 coincide. Through the auxiliary plate 44, the lower opening of the transparent cover 42 is blocked, and a plurality of transparent covers 42 are fitted to the upper end of the auxiliary plate 44 at equal intervals. The transparent cover 42 and the auxiliary plate 44 are used in cooperation to protect the broken wire. A connecting plate 46 is arranged between two adjacent transparent covers 42. Through the connecting plate 46, two adjacent transparent covers 42 are connected. Two notch grooves 421 extending to the left and right ends of the transparent cover 42 respectively and penetrating through the transparent cover 42 are formed by downward depression on the upper end surface of the transparent cover 42. A plurality of first columns 62 respectively penetrate through a plurality of notch grooves 421 on one side, and a plurality of second columns 82 respectively penetrate through a plurality of notch grooves 421 on the other side. The two notch grooves 421 are used in cooperation to enable the first column 62 and the second column 82 to penetrate through the transparent cover 42.

[0026] On the left and right inner wall surfaces of the housing 2, grooves 21 are formed by outward depression. The two grooves 21 are used in cooperation to provide installation spaces for the lead screw 41 and a plurality of guide rods 22 respectively. The lead screw 41 is rotatably connected in one groove 21. Through the lead screw 41, the first movable seat 43 moves up and down, and the fixed part of the driving device with the output shaft connected to the lead screw 41 is installed on the upper end of the housing 2. Through the driving device, the lead screw 41 is driven to rotate. The driving device can adopt the motor 4. Then, a plurality of guide rods 22 are installed in the other groove 21 at equal intervals. The plurality of guide rods 22 are used in cooperation to guide the movement of the second movable seat 45. The right end of the first movable seat 43 located on the left side of the fourth plate 8 and slidably connected to one groove 21 is connected to the left end of the transparent cover 42 located in the middle. The first movable seat 43 is connected to the outer end of the lead screw 41 through a ball screw pair. Through the first movable seat 43, the structure formed by a plurality of transparent covers 42 and a plurality of connecting plates 46 moves up and down. The second movable seat 45 located on the right side of the first plate 6 and slidably connected to the other groove 21 extends out of the outer side of the groove 21 and is connected to the right end of the transparent cover 42 located in the middle. A plurality of guide rods 22 penetrating through the second movable seat 45 are all slidably connected to the second movable seat 45. Through the second movable seat 45, the up and down movement of the structure is assisted. Two straight cylinders 31 are respectively installed on the front end of the first movable seat 43 and the front end of the second movable seat 45. Through the straight cylinders 31, installation spaces for components such as the first guide plate 33 are provided. Two first rods 32 respectively extending into the two straight cylinders 31 are slidably connected to the front ends of the two straight cylinders 31, and the other ends of the two first rods 32 are connected to the rear end of the cover plate 3. Through the first rods 32, an installation carrier for the first guide plate 33 is provided. Then, two first guide plates 33 respectively slidably connected in the two straight cylinders 31 are respectively installed on the rear ends of the two first rods 32. Through the first guide plates 33, pressure is applied to the first elastic member 34. The first elastic member 34 is arranged between the rear end of the first guide plate 33 and the inner rear wall of the straight cylinder 31. Through the first elastic member 34, components such as the first guide plate 33 can return to their original positions. The first elastic member 34 can be a spring. A first clamping groove is formed by outward depression on the inner wall of the straight cylinder 31. Through the first clamping groove, an installation space is provided for the first limiter, and the first limiter located outside the first rod 32 and attached to the front end of the first guide plate 33 is assembled on the first clamping groove. Through the first limiter, the installation between the first guide plate 33 and the straight cylinder 31 is restricted. The first limiter can be a snap ring.

[0027] Before use, first select liquid media of different substances, and then immerse multiple wires to be detected into different liquid media respectively, so as to perform adjustable weather resistance test operations on the wires subsequently. Then take out the wires to be detected, and then start the motor 4 to drive the screw rod 41 to rotate. Since the screw rod 41 is connected to the first movable seat 43 through a ball screw pair, the rotation of the screw rod 41 will cause the first movable seat 43 to move upward along the corresponding groove 21, and with the assistance of the second movable seat 45 and multiple guide rods 22, the structure formed by multiple transparent covers 42 and multiple connecting plates 46 will move upward to the limit position; During the upward movement of the first movable seat 43 and the second movable seat 45, components such as the two straight cylinders 31 and the two first rods 32 will move upward, thereby causing the cover plate 3 to tilt upward, so that the cover plate 3 opens. At the same time, relative movement occurs between the first rod 32 and the first guide plate 33 and the straight cylinder 31, thereby compressing the first elastic member 34 and causing the first elastic member 34 to generate an elastic force; Then, using components such as the second movable plate 81, the second pressing block 83, the third rod 811, the third guide plate 812, the second positioning column 813, the second clamping groove, and the second spiral groove 831, the wires to be tested are wound around the outer end of the second column 82 in an orderly manner. Then, using components such as the first movable plate 61, the first pressing block 63, the first positioning column 611, the second guide plate 612, the second rod 613, the first clamping groove, and the first spiral groove 631, the other end of the wires to be tested is wound around the outer end of the first column 62 in an orderly manner, so as to perform a winding installation on multiple wires to be tested; Then, using components such as the motor 4, the screw rod 41, the first movable seat 43, and the second movable seat 45, the structure is moved downward to contact the upper end of the auxiliary plate 44. At the same time, with the assistance of the elastic force of the first elastic member 34, the cover plate 3 is moved downward again and returns to its original position. At this time, multiple wires are respectively located in multiple spaces formed by multiple transparent covers 42 and the auxiliary plate 44, realizing independent protection for multiple wires, effectively reducing the probability of interference between the disconnected wire and other wires due to the disconnection of a certain wire, effectively reducing the probability of errors in the data collected by other wires during the test due to the interference of the disconnected wire, and effectively ensuring the accuracy of the weather resistance test results; Then, the light generator 5 is used to simulate sunlight passing through multiple transparent covers 42 and irradiate multiple coiled wires, thereby conducting a weather resistance test on the multiple wires. When the multiple wires are irradiated for a predetermined time, components such as the electric push rod 71, the push plate 7, multiple functional grooves 74, multiple third plates 73, multiple third elastic members 76, and multiple second plates 72 are used to apply tensile forces to the multiple wires after the weather resistance test simultaneously, thereby conducting a tensile test on the multiple wires after the weather resistance test. At the same time, the collector 77 collects the tensile test data of the corresponding wires, analyzes and calculates the collected tensile test data, so as to determine the weather resistance of the wires.

[0028] Embodiment 3: Before conducting the weather resistance test, a liquid medium is usually infiltrated onto the wire to lay a foundation for subsequent tests. In the test preparation stage, through the combined use of components such as the second movable plate 81, the second pressing block 83, the third rod 811, the third guide plate 812, the second positioning column 813, the second clamping groove, the second spiral groove 831, the first movable plate 61, the first pressing block 63, the first positioning column 611, the second guide plate 612, the second rod 613, the first clamping groove, and the first spiral groove 631, the two ends of the wire to be tested can be respectively and orderly wound around the outer ends of the first column 62 and the second column 82. This ingenious design greatly reduces the possibility of damage at the clamping point position of the wire during the test.

[0029] However, there are obvious drawbacks in the wire installation link. Since the wire infiltrated with the liquid medium needs to be held manually during the operation, this behavior is extremely likely to cause local contamination of the wire. And this kind of contamination is very likely to cause interference phenomena in the weather resistance test, greatly increasing the probability of errors in the data collected by the wire during the test, and thus affecting the accuracy of the weather resistance test results.

[0030] To solve the above problems, as Figures 10 - 12 shown, a plurality of collection boxes 441 located inside the housing 2 and between the first plate 6 and the fourth plate 8 are equidistantly installed at the lower end of the auxiliary plate 44, and the auxiliary plate 44 is made of a filter screen. The auxiliary plate 44 and the plurality of collection boxes 441 are used in combination to filter and recycle different liquid media, and a plurality of water tanks 11 are equidistantly installed in the base 1. Through the plurality of water tanks 11, the liquid media of different substances for detection are classified and stored. Then, a recovery pipe 442 whose lower end passes through the base 1 and extends into the water tank 11 is connected and installed at the lower end of the collection box 441. Through the recovery pipe 442, the collection box 441 and the water tank 11 are connected and arranged; A plurality of water pumps 12 respectively connected to a plurality of water tanks 11 are equidistantly arranged on the inner bottom end of the base 1. Through the water pumps 12, the liquid medium in the water tanks 11 is pumped, and a plurality of water pipes 13, one end of which passes through the housing 2 and the base 1 and is respectively connected to the plurality of water pumps 12, are equidistantly installed at the lower end of the first plate 6. The other ends of the plurality of water pipes 13 all penetrate through the first plate 6 and respectively extend into the plurality of first columns 62. Through the water pipes 13, the water pumps 12 are connected to the auxiliary pipes 14 in a communicating arrangement; A plurality of auxiliary pipes 14 respectively connected to the plurality of water pipes 13 and respectively located in the plurality of transparent covers 42 are respectively installed on the left ends of the plurality of first columns 62. The other ends of the plurality of auxiliary pipes 14 are respectively slidably connected to the outer ends of the plurality of second columns 82. Through the auxiliary pipes 14, an installation carrier is provided for the spray pipes 141, and a plurality of spray pipes 141 located between the first column 62 and the second column 82 are equidistantly connected and arranged at the outer ends of the auxiliary pipes 14. The plurality of spray pipes 141 are used in cooperation to spray the liquid medium on the wire.

[0031] Before use, first select liquid media of different substances, then store the liquid media of different substances in the plurality of water tanks 11 respectively. Then, by using components such as the motor 4, the lead screw 41, the first movable seat 43, the second movable seat 45, and the plurality of guide rods 22, the structure formed by the plurality of transparent covers 42 and the plurality of connecting plates 46 is moved upward to the limit position. With the assistance of components such as the two straight cylinders 31 and the two first rods 32, the cover plate 3 is opened. Then, by using components such as the second movable plate 81, the second pressing block 83, the third rod 811, the third guide plate 812, the second positioning column 813, the second clamping groove, and the second spiral groove 831, the wire to be tested is orderly wound around the outer end of the second column 82. Then, by using components such as the first movable plate 61, the first pressing block 63, the first positioning column 611, the second guide plate 612, the second rod 613, the first clamping groove, and the first spiral groove 631, the other end of the wire to be tested is orderly wound around the outer end of the first column 62, so as to perform a winding installation on multiple wires to be tested. At this time, a plurality of spray pipes 141 are provided on the outermost sides of the wires to be tested; Then, components such as the motor 4, the lead screw 41, the first movable seat 43, and the second movable seat 45 are used to lower the structure and make it contact the upper end of the auxiliary plate 44. At the same time, components such as the two straight cylinders 31, the two first rods 32, and the two first elastic members 34 cause the cover plate 3 to close. At this time, multiple wire rods are respectively located in multiple spaces formed by the multiple transparent covers 42 and the auxiliary plate 44, and the multiple wire rods can be independently protected. Then, multiple water pumps 12 are started, and then the liquid media of different substances in the multiple water tanks 11 are pumped. Then, the pumped liquid media enter the corresponding auxiliary pipes 14 through the water pipes 13. Then, the liquid media in the auxiliary pipes 14 are split into multiple spray pipes 141, and the multiple spray pipes 141 are used to spray the liquid media onto the corresponding wire rods, so as to spray the liquid media of different substances onto the multiple installed wire rods, effectively reducing the probability of contamination and the like of the liquid media on the wire rods during the installation process, effectively reducing the probability of interference and the like of the wire rods in the weather resistance test, effectively reducing the probability of errors in the data collected during the test of the wire rods, and effectively ensuring the accuracy of the weather resistance test results; At the same time, the transparent cover 42 will block the sprayed liquid media, so that the excess liquid media after spraying will fall within the limited range of the filter screen. The filter screen will filter the fallen liquid media, and then the filtered liquid media will enter the corresponding collection box 441, so as to recycle the liquid media. Then, the liquid media in the collection box 441 return to the corresponding water tank 11 through the recovery pipe 442, realizing the recycling and reuse of the liquid media, so that the liquid media can be recycled; Then, a light generator 5 is used to simulate sunlight to irradiate the multiple wire rods installed in a coiled manner, and then a weather resistance test is carried out on the multiple wire rods. When the multiple wire rods are irradiated for a predetermined time, components such as the electric push rod 71, the push plate 7, the multiple functional grooves 74, the multiple third plates 73, the multiple third elastic members 76, and the multiple second plates 72 are used to apply tensile forces to the multiple wire rods after the weather resistance test at the same time, and then a tensile test is carried out on the multiple wire rods after the weather resistance test. At the same time, the collector 77 collects the tensile test data of the corresponding wire rods, and analyzes and calculates the collected tensile test data, so as to determine the weather resistance of the wire rods.
