The utility model discloses a PCB (printed circuit board) storage device, which relates to the technical field of PCB processing appliances and comprises a support frame, a bottom plate is fixedly connected to the bottom of the support frame, a plurality of wheels are arranged on the bottom plate, a mounting plate is arranged at the top of the bottom plate and is welded on the support frame, a plurality of fixing blocks are vertically welded on the inner wall of the support frame at equal intervals, a bearing plate is arranged on each fixing block, and the bearing plates are arranged on the bottom plate. According to the PCB storage box, through the arrangement of the connecting base, the box pulling plate can be prevented from loosening, and it is guaranteed that PCBs are not affected by the external environment in the storage process; through the arrangement of the connecting piece, the storage box body can be conveniently mounted and dismounted; through the arrangement of the lifting component, the bearing plate can be accurately lifted or descended to the needed position, and the problems that according to a traditional PCB storage device, PCBs stored at high positions are inconvenient to take and place, and potential safety hazards such as high-altitude falling exist are solved.

The embodiment of the present invention discloses a correction device suitable for a deformed side door of a truck compartment, comprising a first component and a second component, wherein a bifurcation is provided at one end of the first component to facilitate locking the end of the deformed weight; the second component is composed of a supporting portion and a clamping portion, wherein the bottom end of the supporting portion is fixed to a preset position of the first component, and can support the first component; the clamping portion of the second component can be inserted into a crossbeam at the bottom of the compartment to play a fixing role, and when an operator applies pressure to the weight through the first component, the correction device can be effectively prevented from deflecting, thereby ensuring that the weight falls into a groove quickly and accurately. The correction device is fast and efficient in processing the deformed weight, and the labor intensity of the operators is greatly reduced. In the process of controlling and correcting the side door weight to enter the groove, it is not easy to rebound or fall off, thereby ensuring the personal safety of the operator. In addition, the correction device is easy to carry, has low maintenance cost, and has high practicality.

This utility model relates to the field of auxiliary material suction technology, specifically an auxiliary material suction mechanism for an automatic packaging line. It mainly includes a machine body, inside which a material conveying assembly and a robotic arm are installed. A transmission assembly is located on one side of the machine body, and a rotating assembly is installed at one end of the robotic arm. A mounting plate is installed on the side of the rotating assembly, and a suction device is located below the mounting plate. It also includes a rotating mechanism located inside the machine body and a fastening mechanism located inside the machine body. After the material is sucked up by the suction device, the robotic arm transfers the material to the top of the box. By activating the motor, pulley two rotates, which in turn drives pulley one and pulley three to rotate via a belt. Pulley one drives the connecting shaft and the suction device to rotate, causing the suction device to rotate the material at a certain angle, ensuring that the material is aligned with the box. This prevents the material from deviating from the box and allows it to fall accurately into the box without needing to be sucked up again, thus improving the quality and efficiency of material packaging.

This invention relates to the field of crusher technology, specifically to a metal scrap anti-jamming crusher, comprising two crushing rollers. Each crushing roller is equipped with: crushing rings, multiple of which are evenly arranged along the axis of the crushing roller, with crushing gaps between adjacent crushing rings; the crushing rings on adjacent crushing rollers are staggered and interlocked into the crushing gaps on the other crushing roller to form intersecting areas; first crushing teeth, evenly distributed around the periphery of the crushing rings along their axis; a telescopic groove, which sequentially penetrates the crushing roller and the crushing rings along the radial direction of the crushing roller; second crushing teeth, movable within the telescopic groove along its extension direction; and a second driving device, disposed within the crushing roller and used to drive the movement of the second crushing teeth. This invention avoids material jamming or metal scrap getting stuck during the crushing process.

The invention relates to the field of phonograph, in particular to a testing device and method for phonograph accessory production. In the prior art, which part of a phonograph has a problem cannot be accurately and specifically judged, and the detection effect is poor. According to the technical scheme, the testing device for phonograph accessory production comprises a base, a shell and a door; the base is fixedly connected with a shell; the shell is movably connected with a door; the device further comprises a bearing plate, a pneumatic push rod, a connecting disc and the like. The base is fixedly connected with a bearing plate; a pneumatic push rod is fixedly connected in the shell; the telescopic part of the pneumatic push rod is fixedly connected with a connecting disc. Compared with a traditional testing technology, the device has the advantages that problems existing on the disc and the central rotating shaft are visually presented through the folds on the first film, and whether the disc and the central rotating shaft have problems or not can be accurately and specifically judged; moreover, whether the defects exist in the cartridge or not is visually presented through the second vibrating film, and whether the defects exist in the cartridge or not can be accurately and specifically judged.
