The invention discloses a vertical hotpot condiment packaging machine, and relates to the field of hotpot condiment sealed packaging, the vertical hotpot condiment packaging machine comprises a packaging machine box frame, the packaging machine box frame is provided and connected with a falling channel for hotpot condiments to fall and pass through; a movable limiting mechanism used for limiting the packaging bags is arranged on the upper portion of the falling channel, and the movable limiting mechanism is installed and connected to the packaging machine box frame. A conveying mechanism used for moving and conveying the packaging bags is arranged below the movable limiting mechanism, and the conveying mechanism is installed and connected to the packaging machine box frame. The packaging machine box frame is further provided and connected with a winding and unwinding mechanism used for winding and unwinding the conveyed packaging bags. The packaging machine is used for packaging hotpot condiments, and in the packaging implementation process, the sealing position of a packaging bag can be finely adjusted, so that the sealing effect of the formed hotpot condiment packaging bag is guaranteed, the fresh-keeping effect of the sealed hotpot condiments is guaranteed, and the storage time is prolonged.

This invention proposes a dedicated welding positioning device for height restriction frames, belonging to the field of height restriction frame welding technology. The device includes a tilting frame, a load-bearing plate, a column positioning frame, and a crossbeam positioning frame. The tilting frame is configured to be driven to rotate around its central axis to switch between vertical and horizontal states. Two load-bearing plates are fixedly installed on each tilting frame to support and position the bottom beam and two sets of diagonal braces. The load-bearing plates are configured to rotate synchronously with the tilting frame to switch between vertical and horizontal states. The column positioning frame supports and positions the columns; the crossbeam positioning frame supports and positions the crossbeams; an adjustment push plate is installed on the tilting frame to push the bottom beam to move along its axial direction; an adjustment push plate is also installed on the crossbeam positioning frame, and this adjustment push plate is configured to switch postures to selectively push the columns or crossbeams to move along their axial direction. Specifically, this invention provides a dedicated welding positioning device for height restriction frames that can switch welding states, improving the convenience of welding operations.

The utility model provides an insulator fixing device of a metering box. The insulator fixing device of the metering box comprises a metering box body, a base, a support and a fixing frame, the base is fixed in the metering box body; the support is fixed to the top face of the base through a first screw, the top face of the support is of an inclined face structure, and a fixing hole, corresponding to the first screw, of the support is of a kidney-shaped hole structure corresponding to the inclined top face of the support. The fixing frame is arranged on the top face of the support in a sliding mode, the top face of the fixing frame is of an inclined face structure with the inclination direction opposite to that of the top face of the support, and through holes for insulator installation are formed in the top face of the fixing frame. According to the utility model, the position of the bracket and the position of the fixing frame relative to the bracket can be adjusted, so that the position of the insulator on the fixing frame in the metering box body can be finely adjusted, the position precision of the insulator is improved, the insulator can be conveniently connected with the connecting plate, and the stable connection between the connecting plate and the insulator is improved.
