Description

Down filling workbench

Technical Field

The utility model belongs to the technical field of down product filling equipment, and particularly relates to a down filling workbench.

Background

As is known in the art, a down product filling system as a complete set generally comprises a down filling bin (the down filling bin comprises an upper down filling bin and a lower down filling bin), a down weighing mechanism connected to the down filling bin for weighing down output by the down filling bin, a down filling mechanism coupled to the weighing bin of the weighing mechanism, and a down filling table accompanying the down filling mechanism. Typical examples of the down filling table are CN203269548U (a full automatic down filling machine), CN205170382U (a portable down filling device for a market), and CN103613061a (a down filling table structure of a down filling machine). The down bobbins after the down filling are not limited to the above patents, and the down bobbins are sealed in time at the down filling station, so that the down can escape outwards from the down bobbin mouth in the process of transferring the down filling station to the next station, namely the sealing station, and the escaped down floats on an operation site, thereby not only damaging the environment, but also wasting valuable down resources and causing two side effects of short weight. The "down filling workbench structure with the down filling port sealing function" provided by CN111252725a is to seal (ultrasonically welded) the down filling port of the down bobbin after the down filling at the down filling station by adding the down filling port ultrasonic welding sealing mechanism and the ultrasonic generator, thereby overcoming the foregoing defects. However, in the actual use process, the following two disadvantages exist: firstly, because the ultrasonic transducer of the structural system of the ultrasonic welding mechanism is positioned below the front side of a dust suction hopper (namely a dust suction hopper) in a longitudinal cantilever state, the probability of the leg collision of a down filling operator and the ultrasonic transducer is relatively high, the position of the ultrasonic transducer is changed, and finally the position dislocation between an ultrasonic transducer welding head positioned at the upper part of the ultrasonic transducer welding head and a cloth pressing foot corresponding to the upper part of the ultrasonic transducer welding head is caused, so that the sealing quality is influenced, and even the sealing cannot be realized; secondly, because one end of a dust collection pipeline is connected to the dust collection interface of the dust collection hopper, the other end of the dust collection pipeline is connected with the dust inlet of the dust collection fan, the dust outlet of the dust collection fan is connected with one end of the dust outlet pipeline, and the other end of the dust outlet pipeline is connected with a dust collection container such as a dust collection bag, so that the distance, namely the path, between the dust collection fan and the dust collection hopper is relatively far, on one hand, the dust collection effect is affected, and on the other hand, the energy conservation is not facilitated because the dust collection fan with relatively high power is required. In view of the foregoing, there remains a need for improvement, and the solutions described below are created in this context.
