Description

Technical Field

[0001] This utility model relates to the field of sampling equipment technology, and more specifically, to a chemical testing sampling device for toys. Background Technology

[0002] To prevent harmful chemicals from posing a threat to children's health, chemical testing of toys is necessary to ensure their safety and compliance. Many chemicals, such as lead, cadmium, phthalates, and formaldehyde, pose potential health risks to children, potentially leading to poisoning, allergies, and developmental delays. Current toy chemical testing requires randomly selecting representative samples from the toys to be tested, and then processing the samples according to the requirements of the testing items, such as cutting, crushing, and dissolving. Specialized software is then used to process and analyze the data, calculating the concentration of the target chemical substance. The most common chemical sampling device is a scraper; a scraper is a device used in daily life for chemical sampling of children's toys and is widely used in the field of chemical testing.

[0003] When using existing scrapers, the toy is first placed in a suitable position, and samples are collected from the edges and fragments of the toy by scraping and cutting it. However, this sampling method has low sampling efficiency.

[0004] Chinese patent CN201110429086.6 discloses a sample surface coating sampling device, comprising: a base, which is horizontally arranged; a sample fixing device slidably mounted on the base along the Y-axis, including a base and clamping devices disposed on both sides of the base, the sample being supported on the base, and the clamping devices clamping and fixing the sample; a blade sliding control device equipped with a blade, which is slidably mounted on the base along the X-axis, and a blade driving device fixedly connected to the blade, driving the blade to rotate and scrape the surface coating of the sample on its upper surface. While this technical solution can effectively improve the sampling efficiency of sample surface coatings and achieve a large sampling volume, it cannot sample from multiple angles. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing sampling equipment that cannot sample from multiple angles, and to propose a chemical testing sampling device for toys that can sample toys from multiple angles.

[0006] To achieve the above objectives, this technical solution provides a toy chemical testing and sampling device, comprising a base, a clamping mechanism, a sliding mechanism, a cutter, and a grinding head. The clamping mechanism and the sliding mechanism are respectively installed at both ends of the base, and the cutter and the grinding head are respectively installed on the sliding mechanism. The sliding mechanism drives the cutter and the grinding head to move closer to or away from the clamping mechanism. The clamping mechanism includes two opposing and coaxially arranged clamping structures, which are rotatably installed on the base.

[0007] In this technical solution, the two clamping structures of the clamping mechanism are used to fix the upper and lower sides of the toy to prevent the toy from shifting during the sampling process. At the same time, the two clamping structures can drive the toy to rotate, thereby realizing multi-angle sampling. The sliding mechanism can drive the cutter or grinding head to move towards the toy and perform automated sampling. During the sampling process, the cutter or grinding head can be selected to cut or grind the toy according to the softness or hardness of the toy or the testing requirements. The cutter can cut and sample softer toys, and the grinding head can grind and sample harder toys. It can replace manual sampling, has high sampling efficiency, and can select the appropriate sampling method for toys of different materials.

[0008] Preferably, in order to install the cutter and grinding head so that their height corresponds to the toy on the clamping mechanism, a support frame is fixed to the top of the sliding mechanism. A switching component is rotatably connected to the support frame. The cutter and grinding head are respectively alternately connected to the switching component. The switching component drives the cutter and grinding head to rotate to switch between the cutter and the grinding head. The switching component can quickly switch the cutter or the grinding head by rotating in the direction of rotation, so that the cutter or the grinding head is aligned with the toy on the clamping mechanism. Then, the sliding mechanism slides to feed and sample. By alternately setting the cutter and the grinding head, mutual interference between the cutter and the grinding head can be avoided when they are working.

[0009] Preferably, to ensure that the cutter or grinding head can work independently and prevent interference, the switching assembly includes a rotating rod, a locking pin, and at least two positioning members. The two ends of the rotating rod are rotatably connected to the support frame. The cutter and grinding head are respectively connected to the middle of the rotating rod. The two positioning members are respectively connected to the end sidewalls of the rotating rod, and each positioning member corresponds to the cutter and the grinding head. Each positioning member forms a positioning hole. The locking pin is located on one side of the support frame, and the positioning member engages with the locking pin to restrict the rotation of the rotating rod. The two positioning members correspond to the cutter and the grinding head respectively. When the cutter is selected for sampling, the rotating rod is rotated so that the positioning member corresponding to the cutter engages with the locking pin through its positioning hole. At this time, the cutter faces the toy on the clamping mechanism. When the grinding head is selected for sampling, the positioning member and locking pin are disengaged from their current engagement state, and the rotating rod rotates a certain angle so that the positioning member corresponding to the grinding head engages with the locking pin through its positioning hole. At this time, the grinding head faces the toy on the clamping mechanism.

[0010] Preferably, in order to drive the cutter or grinding head to rotate for sampling on the toy, a first drive motor is provided on the rotating rod. The drive end of the first drive motor is coaxially connected to a transmission shaft. The cutter is fixed to the side wall of the transmission shaft, and the grinding head is fixed to the end of the transmission shaft. When the cutter is used for cutting sampling, the drive end of the first drive motor drives the transmission shaft to rotate. The cutter rotates and, driven by the sliding mechanism, approaches the toy on the clamping mechanism for cutting sampling. When the grinding head is used for grinding sampling, the drive end of the first drive motor drives the transmission shaft to rotate. The grinding head rotates and, driven by the sliding mechanism, approaches the toy on the clamping mechanism for grinding sampling. Since the grinding head is fixed to the end of the transmission shaft, the grinding head and the cutter are arranged perpendicularly. When the drive end of the first drive motor drives the cutter and the grinding head to rotate simultaneously, interference between the cutter and the grinding head can be avoided as long as they are fixed by their corresponding positioning parts and locking pins.

[0011] Preferably, in order to move the cutter and grinding head closer to or further away from the toy on the clamping mechanism, the sliding mechanism includes a slide rail, a slider, a rack, a gear, and a second drive motor. The slide rail and the rack are respectively fixed on the base and arranged side by side. The support frame is vertically fixed on the slider. The slider is slidably connected to the slide rail. The second drive motor is connected to the slider. The drive end of the second drive motor is connected to the gear. The gear meshes with the rack. The drive end of the second drive motor drives the gear to rotate. The gear rotates on the rack, causing the slider to move along the slide rail. The forward and reverse rotation of the second drive motor controls the forward and reverse movement of the slider.

[0012] Preferably, for installing the clamping structure, a fixed seat is installed on the base, a slide rod is slidably connected to the top of the fixed seat, and a telescopic structure is installed on one side of the fixed seat. The telescopic direction of the telescopic structure is the same as the sliding direction of the slide rod. The telescopic end of the telescopic structure is connected to the slide rod. A platform parallel to the base is connected to the top side of the slide rod. One clamping structure is connected to the bottom of the platform, and the other clamping structure is connected to the base. Initially, the telescopic end of the telescopic structure extends, driving the slide rod to its highest point, maximizing the distance between the two clamping structures. The toy is placed between the two clamping structures. Subsequently, the telescopic end of the telescopic structure retracts, and the two clamping structures simultaneously apply a certain pressure to the toy to clamp it securely. By controlling the distance between the clamping structures, toys of different sizes can be accommodated.

[0013] Preferably, in order to rotate the clamping structure to meet the multi-point sampling of the toy, the platform is provided with a third drive motor, the drive end of the third drive motor passes through the platform and is connected to one of the clamping structures, the base is rotatably connected to a rotating shaft opposite to the drive end of the third drive motor, and the other clamping structure is connected to the top of the rotating shaft.

[0014] Preferably, the base is provided with a fourth drive motor, the drive end of the fourth drive motor is connected to a drive wheel, the rotating shaft is connected to a driven wheel, the drive wheel and the driven wheel are connected, the third drive motor and the fourth drive motor rotate synchronously, wherein the fourth drive motor drives the drive wheel to rotate, and the drive wheel drives the driven wheel to rotate, thereby realizing the relative rotation of the two clamping structures, thereby realizing the rotation of the toy.

[0015] Preferably, in order to accommodate toys of different shapes, the clamping structure includes a chuck and at least three elastic claws. The at least three elastic claws are respectively spaced apart on the periphery of the chuck. One chuck of the clamping structure is connected to the bottom of the platform, and the other chuck of the clamping structure is connected to the base. In use, the top and bottom of the toy abut against the two chucks respectively, and each elastic claw abuts against the outer periphery of the toy to ensure that the toy is clamped.

[0016] Preferably, in order to prevent the toy from slipping out during the sampling process, the chuck is provided with a rubber pad, which serves as an anti-slip pad.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The toy chemical testing and sampling device of this utility model can clamp the toy to prevent it from loosening through a clamping mechanism. The third and fourth drive motors drive the two clamping structures to rotate, causing the toy to rotate and enabling multi-point sampling of the toy.

[0019] 2. It can switch between the cutter and the grinding head by rotating the switching component according to the hardness of the toy. It can automatically sample toys of different hardness through two sampling methods, with high sampling efficiency and convenient switching between sampling methods.
