The utility model discloses a raw material screening device for rubber production, and belongs to the technical field of rubber pad production. The raw material screening device for rubber production comprises a bottom plate, a supporting frame fixedly installed on the bottom plate, a shell arranged on the supporting frame, a feeding pipe fixedly installed on the shell, a screen fixedly installed in the shell and a shaking mechanism arranged on the supporting frame and used for screening rubber raw materials more sufficiently. Through cooperative use of the devices and the arrangement of the shaking mechanism, after rubber raw materials are added into the shell, the shell and the screen cloth with filter holes different in size in the shell shake back and forth, and when the feeding amount of the rubber raw materials is too large, the situation that fine particles above a stacking layer are blocked by large particles at the bottom is reduced; the rubber raw materials can make full contact with the screen, the screening efficiency is improved, and then the quality of final finished products is improved.

The invention discloses an interventional valve ring device and an interventional valve device. The interventional valve ring device and the interventional valve device can be used for mitral valve and tricuspid valve lesions. The interventional valve ring device is mainly composed of a valve ring, a valve ring conveying system, a fixing nail and a fixing nail conveying system. The interventional valve is mainly composed of a fixing support, a supporting support, a supporting support covering film and valve leaflets. The interventional valve ring and the interventional valve enter the heart through the interventional delivery system and can pass through the apex of the heart, the femoral vein, the jugular vein or the subclavian vein, the right atrium or the left atrium. The interventional valve is fixed in the interventional valve ring, and a minimally invasive, safe and effective treatment method can be provided for a patient.

The utility model discloses an adjustable gas transmission assembly suitable for respiratory therapy equipment, the gas transmission assembly comprises a gas inlet and a gas outlet, the gas transmission assembly further comprises a first gas transmission section and a second gas transmission section, the first gas transmission section is internally provided with a first gas transmission channel communicated with the gas inlet, and the second gas transmission section is internally provided with a second gas transmission channel communicated with the gas outlet; the first gas transmission section and the second gas transmission section are telescopically connected through a communicating piece, and a communicating pipeline for communicating the first gas transmission channel and the second gas transmission channel is arranged in the communicating piece; the second gas conveying section can move relative to the first gas conveying section through the communicating piece so as to adjust the relative distance between the first gas conveying section and the second gas conveying section. According to the gas transmission assembly, the first gas transmission section and the second gas transmission section are connected through the communicating piece, and the relative position between the second gas transmission section and the first gas transmission section can be adjusted through the communicating piece according to users with different head circumference sizes, so that the wearing comfort of the gas transmission assembly is improved, and the adaptability of the gas transmission assembly is enhanced.

The utility model relates to the technical field of catheter fixing tools, in particular to an ERCP postoperative nasobiliary drainage tube fixing device which comprises a main support made of silica gel materials, a plurality of adjusting assemblies are installed on the main support in a sliding mode, each adjusting assembly comprises a sliding sleeve, a clamp assembly is installed on the outer wall of each sliding sleeve, and the sliding sleeves are arranged on the main support in a sleeved mode and matched with the main support in a sliding mode. The clamp assembly comprises a base, two limiting plates are symmetrically installed on the base, and clamping plates are installed on the inner sides of the two limiting plates. According to the fixing device for the nasobiliary drainage tube after the ERCP operation, the nasobiliary drainage tube can be firmly fixed through the designed adjusting assembly and the designed clamp assembly, and the situation that the drainage tube moves or falls off due to movement of a patient is effectively avoided. The stability of the drainage tube is jointly ensured through sliding fit of the sliding sleeve and the main support and tight clamping of a limiting plate and a clamping plate in the clamp assembly, so that normal discharge of bile is guaranteed, and the risk of biliary obstruction and infection is reduced.

The invention relates to the technical field of visual inspection, and particularly discloses printing visual inspection equipment based on industrial vision, which comprises an inspection machine body, a conveying assembly penetrating into the inspection machine body, an industrial camera fixedly connected to the top of the inner side of the inspection machine body, and a flattening assembly arranged on the inner side of the inspection machine body and used for flattening the inner side of the inspection machine body. The flattening assembly comprises a frame arranged in the detection machine body, ventilation frames are rotationally connected to the two sides of the front end and the rear end of the frame, connecting blocks are fixedly connected to the bottoms of the multiple ventilation frames, an exhaust pipe is rotationally inserted between every two opposite connecting blocks, and rolling shafts are rotationally connected to the outer sides of the exhaust pipes. A torsion spring is fixedly connected between the top of the frame and the frame, through cooperation of the structure, the rolling shaft can move to the position of a crease of the insertion tongue, the insertion tongue is turned over to be flat, the situation that when a paper box is pressed through glass, the insertion tongue blocks the visual detection position can be reduced, and therefore the visual detection precision is improved.

This utility model belongs to the field of data cable production technology, specifically a manual inspection production line for data cable production, including a machine body and a filling device. A conveyor belt is fitted over the surface of the machine body, and a support frame is fixedly connected to the upper surface of the machine body. The filling device is located on the side wall of the machine body and includes two support blocks. The side walls of the two support blocks are fixedly connected to the side wall of the machine body. A placement frame is fitted over the surface of the two support blocks, and guide rollers are rotatably connected to the surface of the placement frame. A reinforcing block is fixedly connected to the surface of the placement frame. Two blocking devices are provided on the upper surface of the placement frame. Each blocking device includes a locking block, the bottom end of which is fixedly connected to the upper surface of the placement frame. A support strip is fitted over the surface of the locking block, and multiple limiting rollers are rotatably connected to the bottom end of the support strip. By setting up the entire device, data cables can be easily moved from one machine body to another, thereby reducing the number of locations where data cables get stuck between two machine bodies.
