The utility model provides a distance-adjustable roller cooling device, which relates to the technical field of roller cooling and comprises an arc-shaped cooling mounting seat, an adjustable connecting piece and a fixed clamping groove seat, an arc-shaped plate is arranged on the inner side of the arc-shaped cooling mounting seat, and the adjustable connecting piece comprises a first connecting plate and a second connecting plate. The first connecting plate is fixed with the mounting base through the fixed clamping groove seat, the second connecting plate is arranged on the outer wall of the arc-shaped cooling mounting seat, a first adjusting groove is formed in the first connecting plate, a second adjusting groove is formed in the second connecting plate, a fastening bolt is arranged in the first adjusting groove, and one end of the fastening bolt penetrates through the second adjusting groove and then is connected with a nut; the fastening bolts are matched with the nuts to connect the first connecting plate and the second connecting plate, and when the roller diameter of the roller is reduced due to abrasion, the arc-shaped cooling mounting seat is adjusted to be close to the roller by moving the mounting position of the second connecting plate on the first connecting plate; and the distance between the cooling nozzle on the arc-shaped cooling mounting seat and the outer wall of the roller is kept constant.

This utility model discloses a flexible suction port for a roving blowing and suction cleaning machine. Its structure includes a suction assembly, a suction port, and an adaptive adjustment mechanism. Through the contact of a roller assembly with the surface of the drafting cover plate, it senses changes in the height of the drafting cover plate in real time and drives the suction port to move along a vertical slide rail, dynamically maintaining a constant distance between the suction port and the drafting cover plate to ensure stable waste absorption. The adaptive adjustment mechanism adjusts the height of the roller support through a strip groove and bolts, and combines stackable weights to dynamically balance the roller contact pressure, adapting to different working conditions. This utility model adopts a modular design; the suction port is fixed by clamps for easy disassembly and maintenance; the weight and number of weights are adjustable, improving pressure control accuracy. Its significant advantages lie in automatically adapting to drafting cover plate deformation and track misalignment, reducing manual intervention, and improving cleaning efficiency by more than 60%. It is suitable for various roving frame equipment and has broad industrial application value.

The radiation detector includes: a positioning component having a through-hole for radiation to pass through; a scintillator having an input surface for receiving radiation passing through the through-hole and converting the radiation into scintillation light; a sensor having a light-receiving surface for receiving the scintillation light converted by the scintillator and detecting the scintillation light; and a lens having a lens that images the input surface of the scintillator and the light-receiving surface of the sensor, respectively. The positioning component has a first positioning part for positioning the scintillator by contacting its input surface, and a second positioning part for positioning the lens by contacting one end face of the lens.
