Description

Technical Field

[0001] The invention relates to the technical field of flame-retardant ABS plastic modification testing, in particular to a modification testing device for environmentally friendly and highly weather-resistant flame-retardant ABS plastic. Background Art

[0002] Flame retardant ABS plastic is an engineering plastic that has flame retardants added to ABS. It has good flame retardant properties. When used in combination, it can reach flame retardant grades such as V-1, which can effectively prevent the combustion of flammable substances and reduce the occurrence of fire accidents.

[0003] Usually, flame-retardant ABS plastics need to undergo modification testing after production, that is, flame-retardant performance testing. Flame-retardant ABS plastics will be made into flat samples of a certain size and hung up for combustion testing. In order to test whether the flame-retardant ABS plastic can reach the V-1 level, it is required that the flame-retardant ABS plastic burns for no more than 10 seconds after two 10-second ignitions, and the dripping matter cannot ignite the cotton pad underneath. If the dripping matter ignites the cotton pad, the sample cannot reach the V-1 level.

[0004] The existing flame retardancy test of flame retardant ABS plastic is conducted manually, and the burning condition of the flame retardant ABS plastic is observed manually with the naked eye. After the test time is too long, the workers' eyes are prone to visual fatigue, resulting in inaccurate flame retardancy test of the flame retardant ABS plastic. In addition, when the drops of flame retardant ABS plastic fall downward and fall onto the cotton pad, the drops of flame retardant ABS plastic are likely to fall onto the drops of the previous batch and cannot come into contact with the cotton pad. As a result, the workers cannot immediately determine whether the drops of flame retardant ABS plastic will ignite the cotton pad, and need to wait for the next drop of flame retardant ABS plastic to fall, which prolongs the flame retardancy test time and reduces the test efficiency of flame retardant ABS plastic.

[0005] Therefore, it is necessary to design a modified testing device for environmentally friendly and highly weather-resistant flame-retardant ABS plastic with accurate flame retardancy testing and high testing efficiency. Summary of the Invention

[0015] 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.

[0016] For example 1, please refer to Figure 1-8 The present invention provides a technical solution: a modified testing device for environmentally friendly, highly weather-resistant and flame-retardant ABS plastic, comprising a test table 1 and several cotton pads 9. One side of the test table 1 is fixedly connected at a forty-five-degree angle with an igniter 4 for igniting methane gas and spraying the flame from the nozzle to the lower end of the test sample. One side of the test table 1 is fixedly connected with a pad 3, and one side of the pad 3 is fixedly connected with a methane bottle 2 containing methane gas. The output end of the methane bottle 2 is connected to the input end pipe of the igniter 4. One side of the igniter 4 is provided with a transmission mechanism 6 for conveying each cotton pad 9 to the bottom of the sample in turn, and one side of the transmission mechanism 6 is provided with a clamping mechanism 5 for clamping the sample and photographing the burning state of the sample and the cotton pad 9. One side of the clamping mechanism 5 is provided with a feeding mechanism 7 for automatically conveying each sample to the inside of the transmission mechanism 6, and the other side of the clamping mechanism 5 is provided with a sorting mechanism 8 for collecting the tested cotton pads 9 and reusing the unburned cotton pads 9.

[0017] The clamping mechanism 5 includes two first support plates 51 fixedly connected to the upper side of the test table 1, a first electric slide rail 59 fixedly connected in the middle of the two first support plates 51, a second U-shaped plate 54 and a first U-shaped plate 53 fixedly connected to one side of the first support plate 51, a second camera 55 and a first camera 52 fixedly connected to one side of the second U-shaped plate 54 and the first U-shaped plate 53, a sliding end of the first electric slide rail 59 fixedly connected to a first double-headed cylinder 58, both ends of the first double-headed cylinder 58 are fixedly connected to a first connecting plate 57, and the other end of each first connecting plate 57 is fixedly connected to a first clamping plate 56.

[0018] Supplementary explanation based on the above structure is as follows: the extension and retraction of the output end of the first double-headed cylinder 58 is used to drive the two first clamps 56 to move closer to or away from each other, so that the two first clamps 56 clamp the test sample or Panasonic test sample, and the first electric slide 59 is used to drive the clamped sample to move up and down. When the tail end of the flame sprayed by the igniter 4 burns the sample, when the tail end of the sample is burned, the first electric slide 59 drives the sample to continue to move downward until the lower end of the sample is close to the tail end of the flame.

[0019] The second camera 55 is used to photograph the sample after the sample has burned for the first ten seconds. Timing is started from the beginning of the shooting until the second camera 55 can no longer capture the burning under the sample, and the timing stops. After the sample burns for the second ten seconds, the test steps are the same as above and will not be elaborated on here. The time of the two sample combustions is added and compared with ten seconds. When the time of the two sample combustions is greater than ten seconds, it means that the sample is qualified. When the time of the two sample combustions is less than or equal to ten seconds, it means that the sample is qualified.

[0020] The first camera 52 is used to capture and image the cotton pad 9 under the sample when the sample is burning. A database and a judgment module are provided inside the first camera 52. The database is provided with identification photos of the upper surface of the cotton pad 9 in different states. After the first camera 52 captures the image of the upper surface of the cotton pad 9, it will compare it with the identification photos of the upper surface of the cotton pad 9 in different states in the internal database, pre-identify the state of the upper surface of the cotton pad 9, and take photos of the upper surface of the cotton pad 9 to distinguish the test results of this sample as qualified or unqualified.

[0021] When the first camera 52 captures that no dripping objects fall onto the upper surface of the cotton pad 9 during the shooting process, the judgment module determines that the sample is qualified, and the transmission mechanism 6 does not move.

[0022] When the first camera 52 captures the dripping objects burning the upper surface of the cotton pad 9 during the shooting, the judgment module determines that the sample is qualified, and the transmission mechanism 6 starts to move and transports the next new cotton pad 9 to the bottom of the next test sample.

[0023] When the first camera 52 captures dripping objects causing the upper surface of the cotton pad 9 to burn during shooting, the judgment module determines that the sample is unqualified, and the conveying mechanism 6 starts to move to convey the next new cotton pad 9 to the bottom of the next test sample.

[0024] When both the first camera 52 and the second camera 55 judge that the sample is qualified, the sample meets the V1 flame retardant standard. When either the first camera 52 or the second camera 55 judges that the sample is unqualified, the sample does not meet the V1 flame retardant standard.

[0025] The transmission mechanism 6 includes a first motor 61 fixedly connected to the upper side of the test table 1, a first reducer 62 is provided on one side of the first motor 61, and the output end of the first motor 61 is fixedly connected to the input end of the first reducer 62, the output end of the first reducer 62 is fixedly connected to the first rotating shaft, the other end of the first rotating shaft is connected to the first fixed plate 66 with a bearing, and the first fixed plate 66 is fixedly connected to the test table 1, the outer side of the first rotating shaft is fixedly connected to the first transmission roller 64, the outer side of the first transmission roller 64 is provided with a metal soft roll plate 65, and one end of the metal soft roll plate 65 is fixed to the first transmission roller 64. Fixed connection, the other end of the metal soft roll plate 65 is fixedly connected to the second transmission roller 69, the interior of the second transmission roller 69 is fixedly connected to the second rotating shaft, one end of the second rotating shaft is connected to the second fixed plate 67 bearing and the second fixed plate 67 is fixedly connected to the test table 1, the other end of the second rotating shaft is provided with a second reducer 63, the other end of the second rotating shaft is fixedly connected to the output end of the second reducer 63, a second motor 68 is provided on one side of the second reducer 63, the output end of the second motor 68 is fixedly connected to the input end of the second reducer 63 and the second motor 68 is fixedly connected to the test table 1.

[0026] Supplementary explanation based on the above structure is as follows: the rotation of the output end of the first motor 61 is used to drive the output end of the first reducer 62 to rotate, thereby driving the first transmission roller 64 to rotate, and winding the metal soft coil 65, thereby moving the cotton pad 9 above the material trough 652 from right to left; the rotation of the output end of the second motor 68 is used to drive the output end of the second reducer 63 to rotate, thereby driving the second transmission roller 69 to rotate, and winding the metal soft coil 65, thereby moving the cotton pad 9 above the material trough 652 from left to right.

[0027] When a new cotton pad 9 is tested, the cotton pad 9 is moved from left to right, and when an old cotton pad 9 is reused, the cotton pad 9 is moved from right to left.

[0028] A plurality of material troughs 652 are evenly arranged inside the metal flexible coil 65 , and an avoidance groove 651 is arranged inside each material trough 652 .

[0029] Supplementary explanation based on the above structure is as follows: the material trough 652 is used to place the cotton pads 9, and each cotton pad 9 is blocked by a metal soft roll plate 65. When one of the cotton pads 9 burns, the metal soft roll plate 65 blocks it, so that the burning of one of the cotton pads 9 will not cause other cotton pads 9 to burn together. The avoidance groove 651 is used to prevent the dripping objects sticking to the top of the old cotton pad 9 from lifting up the old cotton pad 9 when the old cotton pad 9 is turned over, causing the old cotton pad 9 to be placed unsteadily.

[0030] The first camera 52 and the second camera 55 are used instead of human eyes to photograph and image the burned sample and the cotton cloth under the sample respectively, so as to quickly and effectively determine whether the sample meets the V1 flame retardant standard, and the cotton cloth is divided into multiple small squares and placed in the material trough 652 of the metal soft roll plate 65 for sequential conveying and testing, which effectively prevents the dripping of two samples from falling on the same position during the test, resulting in a delay in the test time. Each cotton cloth is separated by the metal soft roll plate 65 and is sequentially conveyed and tested, which effectively prevents the burning of a single cotton cloth from causing other untested cotton cloths to burn together, resulting in a waste of resources, thereby achieving a high safety effect.

[0031] In the second embodiment, during the process of pushing the cotton pad 9 into the material trough 652, since the material of the cotton pad 9 is too soft, when the bottom cotton pad 9 is pushed, the multiple cotton pads 9 above press the bottom cotton pad 9. Since the bottom cotton pad 9 is pressed by the multiple cotton pads 9 above during the pushing process, when the push plate 75 pushes, the bottom cotton pad 9 is difficult to be pushed out from the inside of the feeding box 71 in a normal manner, and its shape will be distorted and deformed. This deformation may make it impossible for the cotton pad 9 to be laid on the top of the material trough 652 in a flat square shape, thereby causing the subsequent dripping of the flame-retardant ABS plastic to be unable to accurately drip on the top of the cotton pad 9, affecting the detection efficiency of the flame-retardant ABS plastic. Therefore, the following structure is designed to solve the above technical problems.

[0032] The feeding mechanism 7 includes a feeding box 71 fixedly connected to the upper side of the test table 1. The interior of the feeding box 71 is divided into a storage cavity 711 and a guide sliding cavity 712. A guide plate 72 is fixedly connected to one side of the feeding box 71 and the guide plate 72 is communicated with the storage cavity 711. A hydraulic cylinder 73 is fixedly connected to one side of the feeding box 71. The output end of the hydraulic cylinder 73 is fixedly connected to the second connecting plate 74. One side of the second connecting plate 74 is fixedly connected to a push plate 75 and a slide plate 76. The push plate 75 and the slide plate 76 are slidably connected to the storage cavity 711 and the guide sliding cavity 712 respectively. The interior of the storage cavity 711 is rotatably connected to two rotating columns 78. The lower end of each rotating column 78 is fixedly connected to a gear 79. The upper end of each rotating column 78 is fixedly connected to a steel sheet 77. The steel sheet 77 is slidably connected to the interior of the feeding box 71. A number of tooth columns 761 are provided on both sides of the slide plate 76, and the number of tooth columns 761 is one-fourth the number of teeth of the gear 79.

[0033] Supplementary explanation based on the above structure is as follows: the storage chamber 711 of the feeding box 71 is used to stack a number of cotton pads 9, and the extension and retraction of the output end of the hydraulic cylinder 73 is used to drive the push plate 75 and the slide plate 76 to slide along the storage chamber 711 and the guide chamber 712 respectively, and the length of the push plate 75 is shorter than the length of the slide plate 76.

[0034] In the initial state, the output end of the hydraulic cylinder 73 is in a fully extended state. When one of the cotton pads 9 needs to be fed into the interior of the material trough 652, the output end of the hydraulic cylinder 73 begins to retract, and the push plate 75 and the slide plate 76 are driven to slide synchronously. The tooth column 761 of the slide plate 76 first contacts the teeth of the gear 79, and the tooth column 761 and the gear 79 are engaged, driving the gear 79 to rotate, thereby indirectly driving the steel sheet 77 to rotate through the rotating column 78. Since there is a gap between each cotton pad 9, the steel sheet 77 is inserted into the bottom cotton pad 9 and the gap with it while rotating. When the tooth column 761 passes through the feed box 71 and no longer meshes with the gear 79, the steel sheet 77 rotates ninety degrees with the rotating column 78 as the axis to enter the interior of the feed box 71, and supports all the cotton pads 9 above the cotton pads 9 that need to be pushed, reducing the extrusion force on the cotton pads 9 pushed downwards. At the same time, one end of the push plate 75 contacts the lowest cotton pad 9 and pushes it. The push plate 75 pushes the lowest cotton pad 9 through the material storage cavity 711 into the top of the guide plate 72, and then is pushed into the interior of the material trough 652 through the guide plate 72.

[0035] When the cotton pad 9 is pushed into the interior of the material trough 652, the output end of the hydraulic cylinder 73 begins to extend, driving the push plate 75 and the slide plate 76 to slide back. When the push plate 75 passes through the storage cavity 711 and completely withdraws to the outside of the feed box 71, the tooth column 761 of the slide plate 76 contacts the teeth of the gear 79, and the tooth column 761 and the gear 79 mesh, driving the gear 79 to rotate, thereby indirectly driving the steel sheet 77 to rotate through the rotating column 78. When the tooth column 761 enters the feed box 71 and no longer meshes with the gear 79, the steel sheet 77 rotates ninety degrees with the rotating column 78 as the axis and rotates out of the interior of the feed box 71. At this time, some cotton pads 9 are no longer supported and fall off. Since the push plate 75 withdraws to the outside of the feed box 71, it will not press on the push plate 75.

[0036] The extension and retraction of the hydraulic cylinder 73 drives the push plate 75 and the slide plate 76 to move, so that before the push plate 75 pushes the cotton pad 9, several cotton pads 9 above the pushed cotton pad 9 are supported, thereby effectively preventing the upper cotton pads 9 from exerting pressure on the lowermost cotton pad 9 when the push plate 75 pushes the cotton pad 9, and preventing the lowermost cotton pad 9 from being distorted and deformed when pushed, thereby achieving the effect of stable conveying of the cotton pad 9.

[0037] In the third embodiment, after the test of one of the cotton pads 9 is completed, if the cotton pad 9 has been burned through, the cotton pad 9 is scrapped. If only one side of the cotton pad 9 has a burnt yellow surface, it means that the other side of the cotton pad 9 can be used again. The existing cotton pad 9 cannot be judged whether it can be reused based on its surface burning condition, which leads to the tested cotton pad 9 being directly discarded, resulting in a waste of resources. Therefore, the following structure is designed to solve the above technical problems.

[0038] The classification mechanism 8 includes a first collecting box 81 fixedly connected to the upper side of the test table 1, a second collecting box 82 is provided on one side of the first collecting box 81, and the second collecting box 82 is fixedly connected to the test table 1, two second support plates 83 are provided on one side of the second collecting box 82, and the second support plates 83 are fixedly connected to the test table 1, and the upper sides of the two second support plates 83 are fixedly connected with a second electric slide rail 84, the sliding end of the second electric slide rail 84 is fixedly connected with a third electric slide rail 85, and the sliding end of the third electric slide rail 85 is fixedly connected with a fourth electric slide rail 89, and the sliding end of the fourth electric slide rail 89 is fixedly connected with a second double-headed cylinder 87, and the two output ends of the second double-headed cylinder 87 are fixedly connected with the third connecting plate 86, and the other end of each third connecting plate 86 is fixedly connected with the second clamping plate 88, and one side of each second clamping plate 88 is fixedly connected with a third motor 881, and the output end of the third motor 881 passes through the second clamping plate 88 and is fixedly connected with the flip plate 882.

[0039] Supplementary explanations based on the above structure are as follows: the first collection box 81 is used to collect cotton pads 9 that can be reused, the second collection box 82 is used to collect cotton pads 9 that have been burned and scrapped, and the sliding of the sliding end of the second electric slide rail 84 is used to drive the fourth electric slide rail 89 to slide through the third electric slide rail 85, so that it stays above the second collection box 82, the first collection box 81 and the tested cotton pad 9 in turn; when the sliding end of the second electric slide rail 84 slides to one-third of the stroke, the fourth electric slide rail 89 is located above the second collection box 82; when the sliding end of the second electric slide rail 84 slides to one-half of the stroke, the fourth electric slide rail 89 is located above the first collection box 81; when the sliding end of the second electric slide rail 84 slides to two-thirds of the stroke, the fourth electric slide rail 89 is located above the tested cotton pad 9.

[0040] The judgment module of the first camera 52 will also judge whether the cotton pad 9 can be reused after judging whether the sample is qualified.

[0041] When the judgment module of the first camera 52 initially judges that the sample is qualified, it is judged that the surface of the cotton pad 9 is only burnt yellow in color, and the cotton pad 9 can be reused. The sliding end of the second electric slide 84 slides to two-thirds of the stroke, and the fourth electric slide 89 is located above the tested cotton pad 9. The sliding end of the fourth electric slide 89 drives the two flip plates 882 to descend to the two sides of the tested cotton pad 9. The two output ends of the second double-headed cylinder 87 retract and drive the two second clamping plates 88 to approach each other, and then drive the two flip plates 882 to approach each other, clamping the tested cotton pad 9, and the sliding end of the fourth electric slide 89 drives the tested cotton pad 9 to rise. During the process, the output end of the third motor 881 rotates one hundred and eighty degrees, thereby driving the flip plate 882 to rotate one hundred and eighty degrees, and then driving the tested cotton pad 9 to flip one hundred and eighty degrees so that the browned side faces down. The fourth electric slide 89 is located above the second collecting box 82. When the sliding end of the second electric slide 84 slides to half of the stroke, the tested cotton pad 9 is located above the first collecting box 81. The fourth electric slide 89 drives the tested cotton pad 9 to descend to the inside of the first collecting box 81. The two output ends of the second double-headed cylinder 87 extend to drive the two second clamps 88 away from each other, and then place the tested cotton pad 9 into the inside of the first collecting box 81.

[0042] When the judgment module of the first camera 52 initially judges that the sample is unqualified, it is determined that the cotton pad 9 is burnt and cannot be reused. By controlling the second electric slide rail 84, the fourth electric slide rail 89 and the second double-headed cylinder 87, the burnt cotton pad 9 is transported to the interior of the second collection box 82. The method of clamping and transporting has been explained above and will not be repeated here.

[0043] When the first collecting box 81 is full, by controlling the second electric slide 84, the fourth electric slide 89 and the second double-headed cylinder 87, each brown cotton pad 9 inside the first collecting box 81 is placed into each material trough 652 in turn. At this time, the output end of the second motor 68 stops rotating, and the rotation of the output end of the first motor 61 drives the output end of the first reducer 62 to rotate, thereby driving the first transmission roller 64 to rotate, and the metal soft coil 65 is wound up, thereby moving the cotton pad 9 above the material trough 652 from right to left, and the old cotton pad 9 is reused for inspection.

[0044] The judgment module of the first camera 52 is used to judge whether the sample is qualified, so as to further judge whether the state of the cotton pad 9 after the test can be reused. After the first collection box 81 is filled with cotton pads 9, the cotton pads 9 above the material trough 652 start to move from right to left, and the old cotton pads 9 are reused for testing, thereby achieving the effect of saving energy.
