The utility model relates to the technical field of plastic uptake product edge cutting, in particular to a forming edge cutting mechanism of a plastic uptake product, which comprises an edge cutting machine, a movable frame is connected to the outer side of the edge cutting machine in a sliding mode, a telescopic air cylinder drives a cutting knife to reset through arrangement of a movable assembly, so that a connecting block pushes a trigger rod and drives a telescopic rod to contract, and the edge cutting machine is used for cutting the plastic uptake product. At the moment, a fixing strip slides in an inclined groove formed in the surface of a connecting plate so as to abut against the connecting plate to move towards the surface close to the cutting knife, when a rotating shaft rotates, a movable shaft, a threaded rod, a sliding block and a toothed plate at the bottom can be driven to move downwards through a belt, and when the toothed plate moves downwards, a gear engaged with the surface and a grinding disc can be driven to rotate; according to the edge cutting device for the plastic uptake product, the used cutting knife is polished, the situation that in the edge cutting process of the plastic uptake product, the cutting knife makes frequent contact with the plastic product and cuts the plastic product, a cutting edge is gradually abraded, and the sharpness is reduced is prevented, the edge cutting quality and precision are improved, and the edge cutting efficiency is improved.

The utility model discloses an ear penetrating device with a hollow pipe, and belongs to the technology of accessory accessories. The ear penetrating device with the hollow pipe comprises a pushing piece, a clamping piece, a piston piece and an elastic piece. The pushing part is provided with a first cavity and a second cavity, the clamping part is located in the first cavity and comprises a first clamping head and a second clamping head, and the hollow pipe is fixed between the first clamping head and the second clamping head. The piston piece is provided with an installation part used for installing the ear stud base and a guide part capable of extending into the second cavity in a sliding mode, and when the guide part slides along the second cavity, the installation part drives the ear stud base to be connected with the hollow pipe. An ear stud is replaced by the hollow pipe, and the hollow pipe is connected to the ear stud seat. After installation, the diameter of the through groove of the hollow pipe is larger than that of the rod body of the ear stud, the through groove is used for inserting the ear stud, and different ear studs can be used conveniently. And the hollow pipe is arranged, so that an operator can be prevented from frequently contacting the ear stud rod body when using the ear penetrating device, and infection is avoided.

Except polymer is centrally prepared every day in construction process, can be operated without people. In construction process, realize automatic airtight addition of auxiliary agent, avoid human and auxiliary agent frequent contact, avoid easy foaming auxiliary agent pollution environment, effectively reduce HSE risk.

This invention relates to the field of abdominal drainage technology, and more particularly to an abdominal drainage system based on real-time hemoglobin monitoring and intelligent early warning. The technical solution includes an abdominal drainage tube, an optical sensing module, a microprocessor module, and a wireless communication module. The microprocessor module is configured to perform moving average filtering and dynamic trend modeling on hemoglobin concentration data; and to trigger early warnings based on preset multi-level alarm conditions. This invention, by real-time and accurate monitoring of hemoglobin concentration in abdominal drainage fluid, combined with intelligent early warning and personalized response mechanisms, overcomes the limitations of traditional manual observation, significantly improving the timeliness and accuracy of bleeding risk identification. Its closed design reduces the risk of infection, while its system integration capabilities optimize medical and nursing workflows, enabling data sharing and remote collaboration. This not only shortens the intervention time window and improves patient prognosis but also frees up nursing resources and improves medical quality, providing a comprehensive and efficient solution for postoperative monitoring.

This utility model relates to the field of tellurium ingot casting technology, and specifically discloses a tellurium ingot casting device, including a furnace, a chute, a casting sump, and a casting machine platform. The furnace includes a crucible, a cover plate, insulating bricks, a heating device, a thermocouple, a first outer shell, a support, a rotating shaft, a connecting shaft, a leak detection port, and a pressure cap. The furnace is mounted on the support and connected by the rotating shaft. The cover plate is connected to the first outer shell through the connecting shaft. The first outer shell is made of stainless steel. The leak detection port is located on the side of the furnace near the chute. The crucible is made of silicon carbide graphite and is fixed to the first outer shell by the pressure cap. The insulating bricks and the heating device are located between the crucible and the first outer shell. This utility model adopts a two-stage zoned temperature-controlled melting and impurity removal method from bottom to top. Impurities easily float to the surface and solidify, resulting in good stratification with the molten tellurium. The impurity removal effect is good, the operation is simple, and the tellurium yield is high. The entire operation process is controlled by PLC, with a high degree of automation, avoiding frequent contact between operators and the high-temperature molten material, and creating a friendly working environment.
