The utility model discloses a dustproof device for welding, and relates to the technical field of welding dust prevention. Comprising the steps that by arranging a power part, an air supply part and the like, dust, harmful gas and the like in the welding process can be collected under the condition that the operable space of the welding table is not affected basically, the space on the welding table can be utilized more efficiently, and the influence of the dust collection process on the welding process is reduced to the minimum; in addition, due to the structural arrangement, observation of welding can not be affected, and the situations of visual obstruction and the like caused by blocking and the like are reduced. According to the welding table and the mounting frame, the welding seat is mounted at the top of the mounting frame and used for welding, the power mechanism is arranged at the bottom of the mounting frame and comprises the air supply part and the power part, the air supply part forms an air screen around the welding seat, and the power part provides power for rotation of the welding seat; the welding seat comprises a bottom plate and a circular pedestal rotating in the middle of the bottom plate, the bottom plate is also a circular plate body, and the diameter of the bottom plate is larger than that of the circular pedestal.

The utility model discloses an adjustable gate valve lead screw protective sleeve which comprises a protective sleeve body, wrinkles are arranged on the outer surface of the protective sleeve body, a set of fixing rings are arranged on the outer surface of the protective sleeve body in a sleeved mode, the two ends of the protective sleeve body are communicated with shrinkage sleeves, one end of each shrinkage sleeve is connected with a mounting ring, and the other end of each shrinkage sleeve is connected with a screw rod. Two through openings are formed in the outer surface of each mounting ring, and fixing balls are connected to the two ends of each tightening belt. According to the device, the protective sleeve body can be conveniently stretched and lengthened through the folds, the tightening belt is matched to be in contact with the inner side wall of the mounting ring, the mounting ring can be conveniently shrunk, the protective sleeve body can be in contact with the lead screw through the fixing ring, the situation that the lead screw rusts is avoided, operation is convenient, and practicability is high. The device does not affect the use of the valve and the observation of the screw rod, is adjustable, can be applied to gate valve screw rods of various specifications to the maximum extent, and is low in cost.

This utility model belongs to the field of feed production technology, specifically relating to a feed pelleting device for feed production. A blower is installed on one side of the feed cylinder, and the feed cylinder is inserted into the upper inner side of the blower. A second cover is fixedly installed on the upper side of the blower, and an exhaust pipe is connected to the upper side of the second cover. A second motor is fixedly installed at the center of the lower side of the blower, and a shaft is fixedly connected to the upper output end of the second motor. A guide mesh plate is fixedly connected to the lower inner side of the blower and the upper side of the second motor. Feed pellets can sequentially pass through the rotating and rolling mesh hopper and the flat mesh disc, greatly increasing the total distance of the fall, thus allowing for a longer drying time and more thorough drying. It can also roll and shape the newly formed feed pellets, making them less prone to loosening. Simultaneously, the airflow blows from bottom to top, continuously drying the surface of the feed pellets. The moisture carried away by the airflow will rise and escape from the feed, preventing the dried feed pellets below from being affected by moisture, ensuring the drying effect.

The utility model discloses a kind of anti-collision safety robot assembly platform, belong to robot assembly platform technical field, its technical scheme main points include stabilizing frame, the bottom of the stabilizing frame is bolted with support structure, the outer side of the support structure is bolted with protective structure, the top of the lifter is bolted with the bottom of mounting block, the outer side of the mounting block is slidably connected with the inner side of support block, the top of the mounting block is bolted with the bottom of safety grating, in the existing robot assembly process, traditional assembly platform is mostly simple desktop platform, relatively lack of safety protection mechanism, when manual operation on assembly platform, make no effective isolation between robot and operator, prone to collision accident, and the mechanical arm moving path of assembly platform is relatively single, difficult to adapt to different assembly needs.

The utility model discloses high frequency automatic carousel fuse machine, include: body, the body includes base and support arm, and the base one side sets up support arm, rotation mechanism sets up in the base top, rotation mechanism includes carousel and surround edge, and surround edge sets up in the base top surface, and carousel is rotatably installed in the surround edge in the base, and the carousel is provided with the station, and the station is fixed with the template, fuse mechanism sets up in the support arm bottom, and fuse mechanism corresponds the station, and fuse mechanism includes high frequency generator and electrode plate, and high frequency generator is driven to go up by the cylinder, and electrode plate installs in high frequency generator one side. Through the transparent PC board guard board of equidistance encircles and sets up in the surround edge top, not only is convenient for operator to observe equipment operating condition, and also utilizes the gap between adjacent guard board and limits the operation range, avoids operator and exposes in high frequency electric field in large area.
