The utility model discloses an air drying device for a pelletizer, and relates to the technical field of pelletization of the pelletizer, the air drying device comprises a rack for bearing plastic strips to move, roll shafts for guiding the plastic strips are arranged at the two ends of the rack, and an air bellow for air drying of the plastic strips is arranged at the position, below the plastic strips, of the rack. And a fan communicated with the air bellow is arranged on the outer side of the air bellow. Roll shafts for guiding plastic strips are installed on the machine frame, when the plastic strips move, the roll shafts rotate to assist the plastic strips in moving and reduce the possibility that the plastic strips fall into the machine frame, an air bellow is arranged on the machine frame and located below the plastic strips, and a draught fan which is arranged on the outer wall of the air bellow and communicated with the air bellow is used for air drying of the plastic strips. And the possibility that the plastic strips are snapped during movement after being heated and dried by the drying device is reduced.

The utility model discloses a kind of stable drive structure of hanger for electroplating production line, it is related to electroplating equipment technical field, include drive assembly, drive assembly is installed on electroplating production line, drive assembly includes transmission chain and the drive gear for driving transmission chain movement, the outside of transmission chain is fixedly provided with multiple racks, multiple racks are continuously and aligned, each rack has array distribution tooth profile structure, tooth profile structure is located rack far from transmission chain side;Hanger body, hanger body is slidably installed on electroplating production line, the three pawls of each ratchet of the scheme are staggered and size decreases, can be simultaneously engaged with the three tooth profile structures adjacent on rack, through multiple teeth contact dispersion backlash error, simultaneously, the gradient design of pawl height and width can adapt to the slight deformation of rack, ensure that there is no obvious gap in meshing process, effectively avoid displacement deviation when hanger moves, reduce the risk of jamming or overlapping.

The utility model relates to the technical field of mixing devices, in particular to a PET (Polyethylene Terephthalate) foam particle mixing device which comprises a mixing box and two groups of screening mechanisms, a discharge port is arranged at the bottom end of the mixing box, the screening mechanisms are used for screening PET foam particles added into the mixing box, and the screening efficiency can be improved by two groups of screening assemblies. Each screening assembly comprises a screening groove, a flow guide pipe, a screening net and a pull rod, a feeding opening is formed in the top of the side edge of the mixing box, the flow guide pipes are connected with the mixing box and communicate with the feeding openings, the bottom ends of the screening grooves communicate with the top ends of the flow guide pipes, and annular grooves are formed in the inner side walls of the screening grooves. The utility model provides a PET (polyethylene terephthalate) foam particle mixing device which can be used for treating large-particle impurities doped in PET foam particles poured into the mixing device or agglomerated foam particles adhered together, so that the mixing effect is improved when the PET foam particles are mixed with other material additives.

The utility model relates to the field of washers, in particular to a firm saddle-shaped washer which comprises a central part and edge parts, the edge parts are smoothly and fixedly arranged on the two sides of the central part, a central hole is formed in the central part, the central part is bent, the edge parts are also bent, each edge part comprises a bent section, and the bent sections are connected with the central hole. The bending section is connected with the central part, and the difference between the width of the central part and the diameter of the central hole is smaller than the width of the bending section. According to the utility model, the central part and the edge part are arranged, so that the bending section at the edge part can bear larger lateral force, and the possibility of bending damage in the transportation process is reduced; in addition, the horizontal section is arranged on the edge part, so that the possibility that the gasket is stressed, bent and damaged in the installation process due to the fact that the end part of the edge part is clamped with the installation plane is reduced.

This disclosure provides an obstacle-crossing method, a cleaning device, and a computer-readable storage medium, relating to the field of cleaning technology. The method is applied to a controller of a cleaning device, which includes drive wheels, casters, a chassis, and a lifting mechanism. The chassis includes a front end and a rear end, with the direction from the rear end to the front end being the forward direction of the cleaning device. In the forward direction, the casters are located between the drive wheels and the front end of the chassis. The method includes: in response to detecting an obstacle that can be crossed at the front end of the chassis, controlling the lifting mechanism to raise the chassis to a first preset height; controlling the drive wheels to move backward a preset distance towards the rear end of the chassis at a first preset speed and then braking, so that the front end of the chassis tilts due to inertia; and controlling the walking state of the drive wheels according to the detected chassis posture. The method provided by the embodiments of this disclosure is simple and can improve obstacle-crossing ability without increasing the structure of the cleaning device.
