Description

Technical Field

[0001] The utility model relates to the technical field of exhaust hoods, in particular to an exhaust device for a digital printing machine. Background Art

[0002] Digital printing machine is a large-format printer industry, and its ink characteristics are water-based dispersed ink. It is printed on transfer paper and then transferred to cloth (artificial chemical fiber cloth) through high temperature. It is mainly used in the printing and dyeing of clothing fabrics. When the digital printing machine is in use, an exhaust fan is required to exhaust the smoke and dust.

[0003] For example, patent publication number CN214295120U, an exhaust device for a digital printing machine, particularly relates to the technical field of printing machines, wherein a bellows is connected between the air suction hood and the fan, an upper connecting seat with a concave structure is fixed to the left side of the lower end of the filter box, and a lower connecting seat with a concave structure is fixed to the left side of the upper end of the air suction hood. The exhaust device used in this digital printing machine controls the forward and reverse rotation of the motor through an external forward and reverse switch of the motor, so that the worm drives the worm wheel to rotate, so that the rope wheel can wrap around or let go of the suspension rope, so that the suction direction of the suction hood can be adjusted left and right; after the suction hood sucks in the air, it is filtered through a primary filter, a high-efficiency filter and an activated carbon filter, and finally discharged from the outlet pipe, so that the exhaust device has the function of filtering the air, which solves the problem that the current exhaust device only extracts air but cannot filter the sucked air, and the problem that the external air is polluted after the exhaust is solved. However, when the above-mentioned suction hood is in use, a grille is installed under the suction hood, which makes it easy for foreign matter to enter the suction hood during use, causing blockage in the dust collection pipeline. For this reason, we propose an exhaust device for a digital printing machine to solve the above problem. Utility Model Content

[0009] Preferably, a push stud is inserted into the outer thread of the fixing frame, and the end of the push stud is in contact with the surface of the connecting plate, so that the connecting plate can be pushed conveniently by pushing the stud.

[0010] Preferably, the cross-section of the fixing pin is set to be rectangular, through holes compatible with the fixing pin are opened on both sides of the air intake hood, and grooves compatible with the fixing pin are opened on both sides of the protective grille. Through the through holes opened on both sides of the air intake hood and the grooves opened on both sides of the protective grille, the fixing pin can pass through the air intake hood and be inserted into the protective grille, which facilitates the installation of the protective grille.

By making the surface length of the driving rod greater than the surface width of the protective grille, the driving rod can conveniently drive the cleaning brush rod to clean the bottom of the protective grille.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The device places the protective grille under the suction hood and positions it through a limit frame. Then, the push stud is rotated to push the connecting plate to move in the fixed frame, so that the connecting plate drives the fixing pins to pass through the suction hood and be inserted on both sides of the protective grille. This effectively facilitates the installation of the protective grille under the suction hood, thereby preventing the suction hood from absorbing foreign matter during operation and causing blockage in the dust collection pipeline.

[0015] 2. The device can drive the reciprocating screw rod to rotate inside the guide frame through the driving motor, so that the moving block can drive the driving rod to reciprocate under the protective grille, making it easier for the cleaning brush rod to clean the surface of the protective grille to avoid clogging of the surface of the protective grille and affecting the adsorption effect of the suction hood.
