Description

Technical Field

[0001] The present invention relates to the technical field of helmet production, in particular to a safety detection device for helmet production. Background Art

[0002] Helmet testing equipment is typically used to test various performance indicators of helmets to ensure they meet safety standards and quality requirements. Helmet testing primarily includes the following aspects: impact absorption, puncture resistance, wearing device stability, field of view, optical performance, ventilation performance, etc.

[0003] A Chinese patent with authorization publication number CN117629556B discloses a quality inspection device for helmet production, comprising a chassis, the top of which is fixedly connected to a rotational positioning mechanism, the interior of which is fixedly connected to a clamping mechanism, allowing testing at different positions within the same surface of a helmet model. However, the above-mentioned device can only manually load, inspect, and remove materials individually for each helmet, and cannot achieve continuous inspection. The inspection efficiency needs to be improved. Summary of the Invention

[0004] The purpose of the present invention is to provide a safety testing device for helmet production, which can achieve continuous testing, high testing efficiency and significantly reduced manual operation intensity.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: including a feeding mechanism, a feeding mechanism and a detection mechanism, The discharging opening that stirs cage connects with the delivery chute charging aperture, and the delivery chute discharging opening is erected at bin top, bin be arranged on the supporting tractor of the present invention on the supporting tractor, and the delivery chute of being raised by bin is erected at bin top, bin be arranged on the supporting tractor of the present invention on the supporting tractor. The lifting mechanism is a pair of fixedly mounted on two ends of the support frame, and the supporting cam is connected with the support frame by the support frame mounting on the support frame, and the supporting cam is connected with the support frame mounting on the support frame. The detection mechanism includes a supporting vertical plate mounted above one side of the supporting frame. The two side plates of the supporting vertical plate are respectively provided with a screw rod 2 and a slide rod 2 on opposite sides. The screw rod 2 and the slide rod 2 are slidably connected with an electromagnetic plate. A connecting hole is provided at the bottom of the electromagnetic plate. A detection head can be magnetically plugged into the connecting hole. The detection head is fixed in the middle of the lifting plate. Parallel limit vertical rods are provided near the screw rod 2 and the slide rod 2. The two limit vertical rods pass through both sides of the lifting plate.

[0006] By adopting the above technical solution, multiple helmets to be tested can be stacked in the loading barrel, and the rotating rod is driven to rotate, and the rotating rod drives the rotating disc to rotate. Since slide groove one and slide groove two are respectively provided on both sides of the rotating disc, and the two are in a relative position rotated 180 degrees in the vertical direction, the shapes of slide groove one and slide groove two are fan-shaped. Therefore, when the lower dividing plate is located at the arc edge of slide groove one, the dividing plate will be close to the helmet to be tested and support the helmet to be tested at the bottom. At this time, the upper dividing plate is located at the connecting edge of slide groove two and will be away from the helmet to be tested. After the rotating rod is rotated 180 degrees, the two dividing plates are driven by slide groove one and slide groove two to move horizontally, the lower dividing plate is away from the helmet to be tested, and the upper dividing plate is close to the helmet, and finally the helmet to be tested at the bottom drops from the loading barrel. , and can fall into the material mold in the subsequent material taking mechanism, which is convenient for subsequent performance testing of the helmets to be tested. When the helmet to be tested at the bottom falls, the upper dividing plate will be on top of the bottom of the second-to-last helmet to be tested. At this time, as the rotating rod rotates 180 degrees again, the upper dividing plate will move away from the helmet to be tested, while the lower dividing plate will approach the helmet to be tested, and the second-to-last helmet to be tested that is now at the bottom will be caught, returning to the initial state. In this way, as the rotating rod rotates one circle, a single helmet to be tested can be discharged. In the continuous rotation of the rotating rod, continuous intermittent discharge of the helmets to be tested is achieved. The above device can replace the existing operation of manually placing helmets, which not only reduces the operating intensity of workers, but also significantly improves overall work efficiency and saves time. The picking mechanism is located above the unloading mechanism. When the picking mechanism is at the bottom, the two ejecting rods are respectively pressed on both sides of the material mold, which can press the material mold and the helmet to be tested on the material mold after the material is picked up. The arc rod and the support frame are connected by a torsion spring. The torsion spring will drive the ejecting rod close to the material mold. At the same time, a vacuum adsorption device is provided in the material mold, which can tightly adsorb the helmet to be tested after the material is picked up on the material mold, thereby improving the stability of the helmet to be tested during movement and testing; when the screw rod rotates, the support frame rises and approaches the unloading assembly. When the support frame rises, the support frame drives the arc plate and the ejecting rod to rise. Since the support vertical plate is fixed, the fixed slide groove on the support vertical plate is connected to the arc plate through a connecting rod. The inclined section of the fixed slide groove moves away from the adjacent ejecting rod in the vertical upward direction. Therefore, when the ejecting rod rises, the connecting rod limited in the fixed slide groove will pull the arc rod away from the material When the material is removed from the mold, the lifting rod is lowered and the rotating rod rotates 180 degrees, and the helmet to be tested on the upper dividing plate is lowered to the lower dividing plate. As the support frame is further lowered, the short rod is retracted to the inclined section, and the two curved plates are close to each other. At this time, the curved plates are close to the mold, that is, the helmet to be tested, and the helmet to be tested is pressed tightly to realize material removal. By combining the material removal mechanism and the material discharge mechanism, the material removal is fully automatic, and the overall work efficiency is significantly improved, saving time. When the material picking assembly moves to the bottom of the detection mechanism after picking up the material, the electromagnetic plate can absorb the lifting plate when it is energized. The electromagnetic plate and the lifting plate can be lifted to a high place when the second screw rotates. The lifting height can be selected according to the intensity of the test required. When the test is carried out, the electromagnetic plate is powered off, and the lifting plate drives the detection head to descend. The detection head performs an impact test on the top of the helmet to be tested. The limit vertical rod guides the detection head in the vertical direction to ensure the smooth implementation of the test. When the test is completed, the second screw rotates, the electromagnetic plate descends, the detection head is attracted and lifted, and the material picking assembly returns to the origin. The helmet after the test can be removed later, and the material picking detection can be started again to achieve continuous detection.

[0008] When the cam is in the vertical direction and the cam is in the vertical direction, the cam is in the vertical direction and the cam is in the vertical direction, and the cam is in the vertical direction and the cam is in the vertical direction, and the cam is in the vertical direction and the cam is in the vertical direction, and the cam is in the vertical direction and the cam is in the vertical direction, and the cam is in the vertical direction and the cam is in the vertical direction, and the cam is in the vertical direction and the cam is in the vertical direction, and the cam is in the vertical direction and the cam is in the vertical direction, and the cam is in the vertical direction and the cam is in the vertical direction, and the cam is in the vertical direction and the cam is in the vertical direction, and the cam is in the vertical direction and the cam is in the vertical direction, and the cam is in the vertical direction and the cam is in the vertical direction,

[0009] The present invention is further configured as follows: the material-taking mechanism also includes a one-way flip component, the one-way flip component includes two parallel circular plates 1 and 2 located at one end of the connecting rod 2, the circular plate 1 is fixed on the connecting rod 2, the circular plate 2 is connected to the connecting rod 2 for limited rotation, the circular plate 1 is provided with a pawl near the inner wall of the circular plate 2, the outer surface of the circular plate 2 is fixed with a gear 1, the inner wall of the gear 1 is provided with a ratchet, the pawl and the ratchet are externally meshed, the gear 1 is externally meshed with the rack 1, the rack 1 is fixed on the vertical plate, the vertical plate is vertically fixed to the horizontal plate, the horizontal plate is vertically fixed to the support vertical plate, and the support vertical plate and the horizontal plate are both fixed in the cover shell 2.

[0011] By adopting the above technical solution, when the support frame drives the material mold to rise, the connecting rod 1 and the connecting rod 2 will both rise. When the short rod 1 of the arc plate slides in the inclined section 1 of the fixed slide groove, the anti-rotation plates at the ends of the connecting rods slide in the limit rods. At this time, the ejecting rod is also separated from the material mold or the helmet after inspection. As the short rod 1 of the arc plate slides to the vertical section 1, the gear begins to mesh with the rack 1, the gear rotates, and the ratchet on its inner wall drives the pawl to rotate. The pawl is fixed on the circular plate 1, thereby driving the circular plate 1 to rotate. Finally, the second connecting rod is driven to rotate, at which time the inspected helmet on the upper material mold can be flipped 180° downward. A material receiving component, such as a conveyor belt, is placed under the second cover shell to automatically output the inspected helmet. After the second connecting rod is flipped 180°, the lower material mold rotates upward. The length of the vertical section is longer than the length of the rack. After the lower material mold is flipped up, the helmet to be tested is taken out while continuing to rise, and the entire process of unloading, taking, testing and discharging is completed continuously, with a high degree of automation and high detection efficiency.

[0012] The present invention is further configured as follows: the cover shell 2 is slidably connected to the screw rod 3 and the slide rod 3 in the support frame 2, the screw rod 3 and the slide rod 3 are fixed in parallel to the short plate of the support frame 2, the long plate of the support frame 2 is fixed to the two ends of the bottom of the fan-shaped plate, the two fan-shaped plates are rotatably connected to the two support plates respectively, the top of the fan-shaped plate on one side is coaxially connected to the output shaft of the motor 3 through a coupling, and the motor 3 is fixed in the support plate.

At the same time, motor 3 can drive the fan-shaped plate, i.e., the material picking assembly, to rotate a certain angle. The helmet to be tested can also rotate at this time, increasing the testing points of the helmet, which is conducive to comprehensively evaluating the quality of the helmet and improving the credibility of the test results. Motor 3 is preferably a stepper motor.

[0018] The present invention is further configured as follows: the two ends of the upper material dividing plate are slidably connected to the slide groove three on the side surfaces of the two fixed plates, and the lower material dividing plate is slidably connected to the slide groove four on the upper end surface of the horizontal plate fixed between the two fixed plates.

[0020] The present invention is further configured as follows: a dividing knife with a triangular cross section is provided at one end of the dividing plate away from the driving disc.

[0021] By adopting the above technical solution, the helmets to be tested can be effectively divided into materials.

[0022] The beneficial effects of the present invention are as follows: multiple helmets to be tested can be stacked in the loading barrel, and the rotating rod is driven to rotate, and the rotating rod drives the rotating disc to rotate. Since a chute one and a chute two are respectively provided on both sides of the rotating disc, and the two are in a relative position rotated 180 degrees in the vertical direction, the shapes of the chute one and the chute two are fan-shaped. Therefore, when the lower dividing plate is located at the arc edge of the chute one, the dividing plate will be close to the helmet to be tested and support the helmet to be tested at the bottom. At this time, the upper dividing plate is located at the connecting edge of the chute two and will be away from the helmet to be tested. After the rotating rod is rotated 180 degrees, the two dividing plates are driven by the chute one and the chute two to move horizontally, the lower dividing plate is away from the helmet to be tested, and the upper dividing plate is close to the helmet, and finally the helmet to be tested at the bottom drops from the loading barrel. , and can fall into the material mold in the subsequent material taking mechanism, which is convenient for subsequent performance testing of the helmets to be tested. When the helmet to be tested at the bottom falls, the upper dividing plate will be on top of the bottom of the second-to-last helmet to be tested. At this time, as the rotating rod rotates 180 degrees again, the upper dividing plate will move away from the helmet to be tested, while the lower dividing plate will approach the helmet to be tested, and the second-to-last helmet to be tested that is now at the bottom will be caught, returning to the initial state. In this way, as the rotating rod rotates one circle, a single helmet to be tested can be discharged. In the continuous rotation of the rotating rod, continuous intermittent discharge of the helmets to be tested is achieved. The above device can replace the existing operation of manually placing helmets, which not only reduces the operating intensity of workers, but also significantly improves overall work efficiency and saves time. The picking mechanism is located above the unloading mechanism. When the picking mechanism is at the bottom, the two ejecting rods are respectively pressed on both sides of the material mold, which can press the material mold and the helmet to be tested on the material mold after the material is picked up. The arc rod and the support frame are connected by a torsion spring. The torsion spring will drive the ejecting rod close to the material mold. At the same time, a vacuum adsorption device is provided in the material mold, which can tightly adsorb the helmet to be tested after the material is picked up on the material mold, thereby improving the stability of the helmet to be tested during movement and testing; when the screw rod rotates, the support frame rises and approaches the unloading assembly. When the support frame rises, the support frame drives the arc plate and the ejecting rod to rise. Since the support vertical plate is fixed, the fixed slide groove on the support vertical plate is connected to the arc plate through a connecting rod. The inclined section of the fixed slide groove moves away from the adjacent ejecting rod in the vertical upward direction. Therefore, when the ejecting rod rises, the connecting rod limited in the fixed slide groove will pull the arc rod away from the material When the material is removed from the mold, the lifting rod is lowered and the rotating rod rotates 180 degrees, and the helmet to be tested on the upper dividing plate is lowered to the lower dividing plate.

DETAILED DESCRIPTION

[0033] The technical solutions of the present invention will be described clearly and completely below with reference to specific embodiments. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0034] Embodiment, a safety testing device for helmet production, such as Figure 1-8 As shown, it includes a feeding mechanism 1, a feeding mechanism 2 and a detection mechanism 3. The feeding mechanism 1 includes a loading barrel 101, which is fixed to the upper end surface of a cover 117. The cover 117 is fixed to the support frame 16. A number of helmets 102 to be tested are placed in the loading barrel 101. Fixed plates 103 are provided at the bottom of the two opposite sides of the loading barrel 101. The two fixed plates 103 are rotatably connected to a rotating rod 104 on the same side. A driving disc 105 is fixed in the middle of the rotating rod 104. The two sides of the driving disc 105 are respectively concave and provided with a slide groove 106. And the chute 2 107, the chute 106 and the chute 2 107 have the same shape and are connected by two arc grooves of different diameters. The chute 106 rotates 180 degrees around the rotating rod 104 and then translates and overlaps with the chute 2 107. The chute 106 and the chute 2 107 are both slidably connected with a short material distribution rod 108. The short material distribution rod 108 is limited and rotated to the end of the material distribution rod 109. The end of the material distribution rod 109 is vertically fixed to one side of the material distribution plate 110. The two material distribution plates 110 are parallel, and the material distribution plate 110 intermittently slides horizontally to the bottom of the loading cylinder 101. The material taking mechanism 2 is located below the material discharging mechanism 1 and includes a material mold 201. The material mold 201 is 2 and fixed to both ends of the connecting rod 1 202. The middle part of the connecting rod 1 202 is fixed on the connecting rod 2 203. The connecting rod 1 202 is perpendicular to the connecting rod 203. The connecting rod 203 is rotatably connected to the support frame 1 204. The support frame 1 204 is slidably connected to the screw rod 1 205 and the slide rod 1 206. The screw rod 1 205 is rotatably connected to the horizontal plate 11. The support frame 1 204 is hinged on both sides. The arc-shaped rod 207 is connected to a lifting rod 213 between the arc-shaped rods 207. A connecting rod 208 is hinged in the middle of the arc-shaped rod 207. The other end of the connecting rod 208 is rotatably connected to a short rod 209. The short rod 209 is limitedly slidably connected to a fixed chute 210. The fixed chute 210 is located in the support vertical plate 211. The fixed chute 210 includes a vertical section 1 and an inclined section 1 from top to bottom. The inclined section 1 on the two support vertical plates 211 located in the same vertical plane gradually moves away from the vertical section 1. The detection mechanism 3 includes a support vertical plate 31 mounted on one side of the support frame 20, and two side plates of the support vertical plate 31 are provided with a screw rod 2 32 and a slide rod 2 33 on opposite sides. The screw rod 2 32 and the slide rod 2 33 are slidably connected with an electromagnetic plate 34, and a connecting hole is provided at the bottom of the electromagnetic plate 34. The connecting hole can be magnetically plugged into the detection head 35, and the detection head 35 is fixed in the middle of the lifting plate 36. Parallel limit vertical rods 37 are provided near the screw rod 2 32 and the slide rod 2 33. The two limit vertical rods 37 pass through both sides of the lifting plate 36. A plurality of helmets 102 to be tested can be stacked in the loading barrel 101. By driving The rotating rod 104 rotates, and the rotating rod 104 drives the rotating disc to rotate. Since the two sides of the rotating disc are respectively provided with a slide groove 106 and a slide groove 2 107, and the two are in a relative position of 180 degrees in the vertical direction, the shape of the slide groove 106 and the slide groove 2 107 is fan-shaped. Therefore, when the lower dividing plate 110 is located at the arc edge of the slide groove 106, the dividing plate 110 will be close to the helmet to be tested 102 and support the helmet to be tested 102 at the bottom. At this time, the upper dividing plate 110 is located at the connecting edge of the slide groove 2 107, and it will be away from the helmet to be tested 102. After rotating 180 degrees, the two dividing plates 110 are driven by the chute 106 and the chute 2 107 to move horizontally. The lower dividing plate 110 is away from the helmet 102 to be tested, and the upper dividing plate 110 is close to the helmet. Finally, the helmet 102 to be tested at the bottom drops from the loading cylinder 101 and can fall into the material mold 201 in the subsequent material taking mechanism 2, which is convenient for the subsequent performance test of the helmet 102 to be tested. When the helmet 102 to be tested at the bottom falls, the upper dividing plate 110 is connected to the bottom of the second-to-last helmet 102 to be tested. At this time, as the rotating rod 104 rotates 1 again 80°, the upper dividing plate 110 is away from the helmet to be tested 102, and the lower dividing plate 110 is close to the helmet to be tested 102, catching the second to last helmet to be tested 102 at the bottom, and returning to the initial state. In this way, as the rotating rod 104 rotates one circle, a single helmet to be tested 102 can be discharged. In the continuous rotation of the rotating rod 104, the continuous intermittent discharge of the helmet to be tested 102 is achieved. The above device can replace the existing manual operation of placing helmets, which not only reduces the operating intensity of workers, but also significantly improves the overall work efficiency and saves time. The picking mechanism 2 is located above the unloading mechanism 1. When the picking mechanism 2 is at the bottom, the two ejecting rods 213 are respectively pressed on both sides of the material mold 201, which can press the material mold 201 and the helmet to be tested 102 on the material mold 201 after the material is picked up. The arc rod 207 is connected to the support frame 1 204 by a torsion spring. The torsion spring drives the ejecting rod 213 close to the material mold 201. At the same time, a vacuum adsorption device is provided in the material mold 201, which can tightly adsorb the helmet to be tested 102 on the material mold 201 after the material is picked up, thereby improving the movement and inspection of the helmet to be tested 102. When the screw rod 205 rotates, the support frame 204 rises and approaches the blanking assembly. When the support frame 204 rises, the support frame 204 drives the arc plate and the ejector rod 213 to rise. Since the support vertical plate 211 is fixed, the fixed chute 210 on the support vertical plate 211 is connected to the arc plate through the connecting rod 208. The inclined section of the fixed chute 210 is away from the adjacent ejector rod 213 in the vertical upward direction. Therefore, when the ejector rod 213 rises, the connecting rod limited in the fixed chute 210 will pull the arc plate The rod 207 is away from the material mold 201. After the short rod 209 enters the vertical section 1 of the fixed slide 210, the arc rod 207 no longer rotates, and the ejecting rod 213 is in the same plane in the vertical direction. As the ejecting rod 213 rises further, the ejecting rod 213 can eventually drive the rotating rod 104 in the feeding assembly to rotate. When it rises to the highest point, the rotating rod 104 rotates 180 degrees, and the dividing plate 110 below retreats to discharge the material. The helmet 102 to be tested falls onto the material mold 201. The material mold 201 is designed to match the helmet. When it is lowered from the highest point, When descending, the ejector rod 213 descends, and the rotating rod 104 rotates 180 degrees again, and the helmet to be tested 102 located on the upper dividing plate 110 is lowered to the lower dividing plate 110. As the support frame 1 204 further descends, the short rod 1 209 retreats to the inclined section 1, and the two arc plates approach each other. The arc plates are now close to the material mold 201, that is, the helmet to be tested 102, and the helmet to be tested 102 is pressed to realize material removal. By combining the material removal mechanism 2 and the material discharge mechanism 1, the material removal is fully automatic, and the overall work efficiency is significantly improved, saving time. When the material picking assembly after picking up the material moves to the bottom of the detection mechanism 3, the electromagnetic plate 34 can absorb the lifting plate 36 when it is energized. The electromagnetic plate 34 and the lifting plate 36 can be lifted to a high place when the screw rod 2 32 rotates. The lifting height can be selected according to the intensity of the test to be required. When the test is carried out, the electromagnetic plate 34 is powered off, and the lifting plate 36 drives the detection head 35 to descend. The detection head 35 performs an impact test on the top of the helmet 102 to be tested. The limiting vertical rod 37 guides the detection head 35 in the vertical direction to ensure the smooth implementation of the test. When the test is completed, the screw rod 2 32 rotates, the electromagnetic plate 34 descends, and the detection head 35 is sucked and lifted. The material picking assembly returns to the origin. The helmet after detection can be removed subsequently, so that the material picking detection can be started again to achieve continuous detection.

[0035] like Figure 1-8 As shown, both ends of the rotating rod 104 are fixed with a connecting rod 2 111, and the other end of the connecting rod 2 111 is vertically limited and rotatably connected to a short rod 2 112, and the short rod 2 112 is limited and slidably connected to the driving chute 113. The two driving chute 113 are located on the side where the two driving plates 114 are close to each other. A spring is provided on the top of the cover 1 117, and the spring drives the driving plate 114 close to the material taking component. The driving chute 113 includes a vertical section 2, a vertical section 3 and an inclined section 2 from top to bottom. , the inclined section 2 gradually approaches the dividing plate 110 in the direction close to the driving disc 105, and the bottom of the two driving plates 114 on the same side are fixed with a connecting plate 115, and the bottom surface of the connecting plate 115 is provided with a groove 116 that matches the ejecting rod 213. When the ejecting rod 213 remains stationary in the vertical direction, it can be snapped into the groove 116. As the ejecting rod 213 rises, the driving plate 114 rises in the housing. At this time, the short rod 212 is in the inclined section 2 of the driving chute 113. The highest point of the drive chute 113 starts to slide, and when the drive chute 113 rises, the drive connecting rod 2 111 rotates clockwise, and the connecting rod 2 111 drives the rotating rod 104 to rotate clockwise until the short rod 2 112 slides to the lowest point of the inclined section 2 of the drive chute 113. At this time, the rotating rod 104 rotates 180 degrees clockwise, and the material mold 201 also finishes taking the material. The ejector rod 213 descends, and the drive plate 114 descends. At this time, the short rod 2 112 starts to slide from the lowest point of the inclined section 2. Since the inclined section 2 faces opposite directions during the rise and fall, the connecting rod 2 111 will continue to rotate clockwise until the short rod 2 112 slides to the highest point of the inclined section 2. The connecting rod 2 111 rotates 180° clockwise, that is, the rotating rod 104 rotates 180° and returns to its original position. The helmet 102 to be tested also just falls onto the dividing plate 110 below. The setting of the spring ensures that the driving plate 114 keeps in contact with the ejecting rod 213, ensuring that the driving plate 114 rises and falls smoothly.

[0036] like Figure 1-8As shown, the material taking mechanism 2 also includes a one-way flip assembly, which includes two parallel circular plates 1 4 and 2 5 located at one end of the connecting rod 203, the circular plate 1 4 is fixed on the connecting rod 203, the circular plate 2 5 is connected to the connecting rod 203 for limited rotation, the circular plate 1 4 is provided with a pawl 6 near the inner wall of the circular plate 2 5, the outer surface of the circular plate 2 5 is fixed with a gear 1 7, the inner wall surface of the gear 1 7 is provided with a ratchet 8, the pawl 6 and the ratchet 8 are externally meshed, the gear 1 7 is externally meshed with the rack 1 9, the rack 1 9 is fixed on the vertical plate 10, and the vertical plate 10 is vertical. It is fixed on the horizontal plate 11, and the horizontal plate 11 is fixed vertically on the supporting vertical plate 211. The supporting vertical plate 211 and the horizontal plate 11 are both fixed in the cover 12. The outer side of the circular plate 25 away from the circular plate 14 is fixed with an anti-rotation plate 13. The anti-rotation plate 13 is sleeved and rotatably connected to the outside of the connecting rod 203. Both ends of the anti-rotation plate 13 are rotatably connected to the rotating wheel 14. Parallel limiting rods 15 are vertically fixed on the horizontal plate 11. The anti-rotation plate 13 can slide between the two limiting rods 15. When the support frame 1 204 drives the material mold 201 to rise, the connecting rod 1 202 and the connecting rod 2 203 will rise. When the short rod 1209 of the arc plate slides in the inclined section 1 of the fixed slide groove 210, the anti-rotation plate 13 at the end of the connecting rod 203 slides in the limit rod 15. At this time, the ejector rod 213 is also separated from the mold 201 or the helmet after inspection. As the short rod 1209 of the arc plate slides to the vertical section 1, the gear 12 starts to mesh with the rack 12, and the gear 12 rotates. The ratchet on its inner wall drives the pawl 6 to rotate. The pawl 6 is fixed on the circular plate 14, thereby driving the circular plate 14 to rotate, and finally driving the connecting rod 203 to rotate. The helmet that has been tested on the upper material mold 201 can be turned 180 degrees downward. A material receiving component, such as a conveyor belt, is placed under the cover shell 12 to automatically output the tested helmet. After the connecting rod 203 is turned 180 degrees, the lower material mold 201 rotates to the upper side. The length of the vertical section 1 is greater than the length of the rack 19. After the lower material mold 201 is turned up, the material of the helmet to be tested 102 is taken out during the continued upward process, and the entire process of unloading, taking out, testing and discharging is completed continuously, with a high degree of automation and high testing efficiency.

[0037] like Figure 1-8As shown, the cover 2 12 is slidably connected to the screw rod 3 17 and the slide rod 3 18 in the support frame 20, the screw rod 3 17 and the slide rod 3 18 are fixed in parallel to the short plate of the support frame 20, the long plate of the support frame 20 is fixed to the two ends of the bottom of the fan-shaped plate 21, and the two fan-shaped plates 21 are respectively rotatably connected to the two support plates 22. The top of the fan-shaped plate 21 on one side is coaxially connected to the output shaft of the motor 3 25 through a coupling. The motor 3 25 is fixed in the support plate 22, and the sides of the two support plates 22 close to each other are provided with a concave Limiting groove one, a protruding slider one is provided on one side of the fan-shaped plate 21, and the slider one is slidably connected to the limiting groove one. The cover shell 2 12 drives the entire material-taking mechanism 2 to move horizontally, and can transport the helmet to be tested 102 after taking the material to the bottom of the detection mechanism 3 for testing. At the same time, the motor three 25 can drive the fan-shaped plate 21, that is, the material-taking component, to rotate a certain angle. The helmet to be tested 102 can also rotate at this time, increasing the detection points of the helmet, which is conducive to comprehensively judging the quality of the helmet and improving the credibility of the test results. The motor three 25 is preferably a stepping motor.

[0038] like Figure 1-8 As shown, screw rod 1 205, screw rod 2 32 and screw rod 3 17 are coaxially fixedly connected to the output shafts of motor 1 23, motor 2 24 and motor 3 25 respectively. The number of slide rod 2 33 is 3. Slide rod 2 33 and screw rod 2 32 are respectively fixed to the ends of the two horizontal plates 11. A protruding slider 2 26 is provided on the outer side surface of the side away from the driving plate 114. The slider 2 26 is slidably connected to the concave limiting groove 2 on the inner wall surface of the cover 1 117. An anti-slip block is provided at the bottom of the cover 117. The anti-slip block is parallel to the ejecting rod 213 and is located below one side of the driving plate 114. The slider 2 26 ensures that the driving plate 114 slides in the vertical direction. The anti-slip block can effectively prevent the driving plate 114 from falling off the cover 117.

[0039] like Figure 1-8 As shown, both ends of the upper dividing plate 110 are slidably connected to the slide groove three on the side surfaces close to the two fixed plates 103, and the lower dividing plate 110 is slidably connected to the slide groove four on the upper end surface of the horizontal plate 118 fixed between the two fixed plates 103, ensuring that the two dividing plates 110 slide in the horizontal direction to divide the materials.

[0040] like Figure 1-8 As shown, a dividing knife 19 with a triangular cross section is provided at one end of the dividing plate 110 away from the driving disc 105 , which can effectively divide the helmets 102 to be tested. Working principle of a safety testing equipment for helmet production: A plurality of helmets 102 to be tested can be stacked in the loading barrel 101. By driving the rotating rod 104 to rotate, the rotating rod 104 drives the rotating disc to rotate. Since a chute 106 and a chute 2 107 are respectively provided on both sides of the rotating disc, and the two are in a relative position of 180 degrees in the vertical direction, the shape of the chute 106 and the chute 2 107 is fan-shaped, so when the dividing plate 110 below is located at the arc edge of the chute 106, the dividing plate 110 will be close to the chute 106. The first and second chute 106 and 107 are used to move the two dividing plates 110 horizontally. The lower dividing plate 110 is away from the helmet 102 to be tested, and the upper dividing plate 110 is close to the helmet 102 to be tested, and the helmet 102 to be tested at the bottom is supported. At this time, the upper dividing plate 110 is located at the connecting edge of the second chute 107, and it will be away from the helmet 102 to be tested. When the rotating rod 104 rotates 180 degrees, the two dividing plates 110 are driven by the chute 106 and the chute 107 to move horizontally. The lower dividing plate 110 is away from the helmet 102 to be tested, and the upper dividing plate 110 is close to the helmet. Finally, the helmet 102 to be tested at the bottom is moved away from the helmet 102 to be tested. The material loading cylinder 101 descends and can fall into the material mold 201 in the subsequent material taking mechanism 2, which is convenient for the subsequent performance test of the helmet to be tested 102. When the helmet to be tested 102 at the bottom falls, the upper dividing plate 110 is received at the bottom of the second-to-last helmet to be tested, and at this time, as the rotating rod 104 rotates 180 degrees again, the upper dividing plate 110 is away from the helmet to be tested 102, and the lower dividing plate 110 is close to the helmet to be tested 102, and the helmet to be tested 102 that is just the second-to-last and is located at the bottom is received, and returns to the initial state. In this way, as the rotating rod 104 rotates one circle, a single helmet to be tested 102 can be discharged, and the continuous intermittent discharge of the helmet to be tested 102 is achieved in the continuous rotation of the rotating rod 104. The above device can replace the existing operation of manually placing helmets, which not only reduces the operating intensity of workers, but also significantly improves the overall work efficiency and saves time. The picking mechanism 2 is located above the unloading mechanism 1. When the picking mechanism 2 is at the bottom, the two ejecting rods 213 are respectively pressed on both sides of the material mold 201, which can press the material mold 201 and the helmet to be tested 102 on the material mold 201 after the material is picked up. The arc rod 207 is connected to the support frame 1 204 by a torsion spring. The torsion spring drives the ejecting rod 213 close to the material mold 201. At the same time, a vacuum adsorption device is provided in the material mold 201, which can tightly adsorb the helmet to be tested 102 on the material mold 201 after the material is picked up, thereby improving the movement and inspection of the helmet to be tested 102. When the screw rod 205 rotates, the support frame 204 rises and approaches the blanking assembly. When the support frame 204 rises, the support frame 204 drives the arc plate and the ejector rod 213 to rise. Since the support vertical plate 211 is fixed, the fixed chute 210 on the support vertical plate 211 is connected to the arc plate through the connecting rod 208. The inclined section of the fixed chute 210 is away from the adjacent ejector rod 213 in the vertical upward direction. Therefore, when the ejector rod 213 rises, the connecting rod limited in the fixed chute 210 will pull the arc plate The rod 207 is away from the material mold 201. After the short rod 209 enters the vertical section 1 of the fixed slide 210, the arc rod 207 no longer rotates, and the ejecting rod 213 is in the same plane in the vertical direction. As the ejecting rod 213 rises further, the ejecting rod 213 can eventually drive the rotating rod 104 in the feeding assembly to rotate. When it rises to the highest point, the rotating rod 104 rotates 180 degrees, and the dividing plate 110 below retreats to discharge the material. The helmet 102 to be tested falls onto the material mold 201. The material mold 201 is designed to match the helmet. When it is lowered from the highest point, When descending, the ejector rod 213 descends, and the rotating rod 104 rotates 180 degrees again, and the helmet to be tested 102 located on the upper dividing plate 110 is lowered to the lower dividing plate 110. As the support frame 1 204 further descends, the short rod 1 209 retreats to the inclined section 1, and the two arc plates approach each other. The arc plates are now close to the material mold 201, that is, the helmet to be tested 102, and the helmet to be tested 102 is pressed to realize material removal. By combining the material removal mechanism 2 and the material discharge mechanism 1, the material removal is fully automatic, and the overall work efficiency is significantly improved, saving time. When the material picking assembly after picking up the material moves to the bottom of the detection mechanism 3, the electromagnetic plate 34 can absorb the lifting plate 36 when it is energized. The electromagnetic plate 34 and the lifting plate 36 can be lifted to a high place when the screw rod 2 32 rotates. The lifting height can be selected according to the intensity of the test to be required. When the test is carried out, the electromagnetic plate 34 is powered off, and the lifting plate 36 drives the detection head 35 to descend. The detection head 35 performs an impact test on the top of the helmet 102 to be tested. The limiting vertical rod 37 guides the detection head 35 in the vertical direction to ensure the smooth implementation of the test. When the test is completed, the screw rod 2 32 rotates, the electromagnetic plate 34 descends, and the detection head 35 is sucked and lifted. The material picking assembly returns to the origin. The helmet after detection can be removed subsequently, so that the material picking detection can be started again to achieve continuous detection.
