A drive mechanism is provided between the rectangular seats and the rotating shafts. This utility model has the following advantages and effects: through a dual electric and manual control structure, combined with gear and rack transmission, laser ranging feedback, stirring to prevent accumulation, and intelligent control technologies, it achieves precise adjustment of the feeding flow rate, stable equipment operation, and emergency fault handling, effectively improving rice processing efficiency and quality.

The utility model discloses a transmission device for a labeling machine, which comprises a labeling machine body, the top of the labeling machine body is fixedly provided with a transmission belt, and the top of the transmission belt is fixedly provided with a support. The twisting disc is firstly rotated, the twisting disc drives the round rod to rotate, the round rod drives the winding wheel to rotate, the winding wheel rotates to drive the steel rope to wind, the steel rope is wound to drive the transverse plate to move upwards, the transverse plate drives the limiting block to move, the pressing roller can move upwards, and then an object is placed at the bottom of the pressing roller. Then a hollow screw sleeve is rotated, meanwhile, a hollow screw rod is controlled by a single hand to avoid rotation, the hollow screw sleeve drives the hollow screw rod to move downwards, the pressing force of a pressing roller can be adjusted through a pressing ring, the label can be conveniently fixed, an existing mode that the label is not fixed and pressed is replaced, and therefore the label can be fixed and pressed; and the tightness between the label and the article is ensured.

This utility model relates to the field of battery electrode sheets and discloses a self-calibration and positioning device for battery rolling rollers. It includes a positioning platform with a hollow side wall and a lifting frame embedded within it. A top plate is horizontally fixed to the top of the lifting frame. A straight rod is fixedly connected to the top of the positioning platform, and a cylinder is fixedly connected to the middle of the straight rod. A retainer is fixedly connected between the top of the cylinder and the top plate. Slider blocks are sleeved on both sides of the straight rod, and a tripod is hinged to the top of each slider. A connecting seat is hinged to the top of the tripod, and the top of the connecting seat is fixed to the bottom of the top plate. Bearing seats are fixedly connected to the bottom of both sides. This self-calibration and positioning device for battery rolling rollers, by incorporating the lifting frame, achieves stable and adjustable lifting and real-time self-calibration positioning of the upper rolling roller relative to the lower rolling roller, eliminating the need for manual disassembly and assembly. This improves electrode sheet thickness control and solves the problem that traditional drilling positioning structures cannot dynamically adjust the rollers.

The application discloses a civil engineering water pipe half-arc cutting assembly, which comprises a feeding mechanism and a transverse cutting mechanism, inner supporting strips are fixedly connected to the left and right sides of the inner wall of the feeding mechanism, a tool seat is installed at the bottom end of the inner cavity of the feeding mechanism, a motor body is installed at the overlapping part of the tool seat, and a screw rod body is installed at the driving end of the motor body. The civil engineering water pipe half-arc cutting assembly is characterized in that, after the motor operates, the driving shaft drives the gear body to rotate through the chain, the shaft rod of the gear body is connected to the steel pipe to be treated, the steel pipe to be treated is located on one side of the cutting knife through the slot holes of the hole seat and the perforated slot holes, when the steel pipe to be treated is cut, the cross bolt is twisted on the screw hole seat, the connecting strips connected to the outer wall of the screw hole seat are displaced downward, the outer wall of the steel pipe to be treated is extruded, the rotation angle of the steel pipe to be treated is adjusted in advance, the extrusion of the connecting strips by the cross bolt is facilitated, and cutting is facilitated.

The invention discloses an automatic butt welding device, and relates to the technical field of automatic welding devices. Comprising a welding mechanism used for welding, a clamping mechanism used for fixing a pipe fitting and a movement control mechanism used for controlling the clamping mechanism to move to achieve butt joint. The clamping mechanism comprises two symmetrically-arranged annular supporting bases, rotatable clamping assemblies are installed on the annular supporting bases, the movement control mechanism controls at least one annular supporting base to be close to the other annular supporting base, and butt joint of pipe fittings at the welding position is achieved. A rotation control mechanism is arranged on one side of the clamping mechanism and used for controlling the clamping assembly to rotate. By arranging the clamping mechanism, a pipe fitting can be placed on the inner side of the clamping mechanism, a thread adjusting seat is screwed on a thread barrel in the direction close to an annular rotating frame by screwing the thread adjusting seat, so that a guide rail bracket translates under the guidance of a guide column, and a sliding ball guide rail is used for pressing a clamping part to realize circumferential clamping of the pipe fitting.
