The robot packaging and stacking system comprises a packaging machine, a bag pressing machine, a weighing and conveyingdevice, a stacking robot and a compacting machine. The weighing and conveying device is located on the right side of the bag pressing machine, and the stacking robot is arranged on the right side of the weighing and conveying device. The compacting machine is arranged behind the stacking robot, and a conveying device is arranged on the lower side. The bag pressing machine comprises a supporting frame, a bag pressing assembly and a vibration conveying device. The supporting frame is erected on the vibration conveying device, and a transmission assembly in the bag pressing assembly drives a pressing assembly to carry out rotary bag pressing. The compacting machine comprises a lifting device, a plate drawing device and a push-on device. A lifting platform in the lifting device is arranged onthe lifting frame in a vertical sliding manner through the lifting assembly. A driving assembly controls a supporting plate to relatively move on the lifting platform left and right. According to therobot packaging and stacking system and the use method, the layout is compact, packaging bag material arrangement and compaction are achieved, materials are prevented from being accumulated in packaging bags, the packaging bags are more compact, and weighing is more precise.

The invention discloses an aluminum alloy door and window bending device which comprises a bottom plate, an angle adjusting driving mechanism is arranged at the upper end of the bottom plate, the angle adjusting driving mechanism is provided with an output end, and the output end of the angle adjusting driving mechanism is connected with a bending angle adjusting mechanism used for adjusting the bending angle of a door frame; the angle adjusting driving mechanism is used for providing power for the bending angle adjusting mechanism; and a hydraulic cylinder is arranged at the end, away from the angle adjusting driving mechanism, of the bottom plate and provided with an output end, and the output end of the hydraulic cylinder is connected with a rod body. According to the aluminum alloy door and window bending device, by arranging a rotating motor and a bending ejection piece, torque is output through the rotating motor, accordingly, the bending ejection piece can be driven to rotate, through the hydraulic cylinder, the bending ejection piece can achieve linear displacement and rotating motion at the same time, thus, the door frame can be bent more easily, treatment similar to polishing can be conducted on on a bending position through rotating motion, the bent part is smoother and more attractive, and the mechanical property is better.

The invention discloses a laparoscopic aspirator with grasping forceps. The laparoscopic aspirator with grasping forceps comprises a handle, a escaping groove, a fixed shaft, a handle, a first rack, asliding sleeve, a second rack, a spring, a pressing block, a rotating wheel, an inner tube, a clamp, a rotating sleeve, a clamping mouth, an outer cavity tube and a pull rod. The laparoscopic aspirator with grasping forceps has a clever structure and powerful function. Firstly, the push-type switch design can facilitate the medical personnel to suck the liquid and mist in the patient body which the convenience of operation is improved, and secondly, the matching effect of the clamping mechanism can not only realize the rapid clamping operation of the diseased tissue in the patient, but also can adjust the angle according to the operation needs, which greatly satisfy the various clinical needs and also effectively avoid the need for the cooperation or frequent replacement of multiple setsof instruments, and finally through the above, the convenience of the medical staff is improved, and the operation time is shortened, thereby achieving a good promotion and application.

The invention discloses an automatic parallel movable template assembly, an automatic parallel static template assembly, and an emission device thereof. The automatic parallel movable template assembly comprises a movable template, a floating template, and a plurality of positioning screws. One end of the movable template is provided with a convex spherical surface (or a concave spherical surface), and the other end of the movable template is connected with second joints of various elbows in a pivoted. One end of the floating template is provided with a corresponding concave spherical surface (or a convex spherical surface), and is disposed on one end of the movable template. Various positioning screws pass through the floating template and the movable template. The automatic parallel static template assembly comprises a static template having one end provided with the convex spherical surface (or the concave spherical surface), and the floating template having the concave spherical surface (or the convex spherical surface) disposed on one end of the static template, and a plurality of positioning screws passing through the floating template and the static template.

The invention discloses an automobile chair framework lifting mechanism. The automobile chair framework lifting mechanism comprises a chair framework body arranged on a base, wherein the front part of the chair framework body is connected with the base through a front lifting device, and the rear part of the chair framework body is connected with the base through a rear connecting rod; the front lifting device comprises two groups of connecting rod assemblies, a synchronous driving rod is connected between the two groups of connecting rod assemblies, the connecting rod assemblies comprise upper connecting rods and lower connecting rods, the upper ends of the upper connecting rods are hinged to the chair framework body, the lower ends of the upper connecting rods are fixed on the synchronous driving rod in a sleeving manner, the upper ends of the lower connecting rods are movably arranged on the synchronous driving rod in a sleeving manner, and the lower ends of the lower connecting rods are hinged to the base. According to the technical scheme, a screw of a screw motor stretches out and draws back, the synchronous driving rod is driven to swing, the upper connecting rods fixedly connected at the two ends of the synchronous driving rod rotate, the lower connecting rods hinged to the upper connecting rods rotate, angles between the upper connecting rods and the lower connecting rods vary, the variation of the whole height of the upper and lower connecting rods is caused, and the purpose of regulating the angle of the chair framework is achieved. Meanwhile, the front lifting device is matched with the rear connecting rod, and the chair framework height is regulated.
