[0030] In order to more clearly illustrate the technical solution of the utility model, the following will briefly introduce the drawings required for the description. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other embodiments can be obtained based on these drawings without creative work. In order to facilitate the understanding of the utility model, the following will be combined with the drawings and specific embodiments to explain the utility model in more detail.
[0031] like Figure 1 , Figure 7 As shown:
[0032] The smoke exhaust device of the coloring box includes a frame 300, a shell 100, a smoke baffle 8, a heat insulating material 5 and two sets of smoke exhaust duct systems. The core part is the two sets of smoke exhaust duct systems. During the operation of the coloring box, the two sets of smoke exhaust duct systems exhaust a large amount of oil smoke generated during the coloring process to prevent the oil smoke from gathering in the coloring box and contaminating the picture on the inkjet printing cloth.
[0033] The shell 100 is welded on the frame 300 , and two sets of smoke exhaust duct systems are installed in the shell 100 .
[0034] like Figure 2 As shown:
[0035] Each smoke exhaust duct system consists of three parts: an exhaust duct 2, a main duct 3 and a grid hole duct 4.
[0036] Working principle of smoke exhaust device duct system:
[0037] The two sets of smoke exhaust duct systems are symmetrically distributed on the left and right, and the two inclined surfaces of the two sets of oil exhaust duct systems form an oil fume collection area 12. The inkjet printing cloth 7 is located at the symmetric center of the two sets of smoke exhaust duct systems when coloring, that is, the two sets of smoke exhaust duct systems are located on both sides of the inkjet printing cloth 7. The inkjet printing cloth 7 passes through the shell 100 and the oil fume collection area 12 from top to bottom. The printed inkjet printing cloth 7 moves from top to bottom. Under the high temperature of the coloring box, the ink on the inkjet printing cloth 7 is thermally sublimated to form a large amount of oil fume. Due to the thermal expansion density reduction, the oil fume moves upward.
[0038] The left end of the exhaust duct 2 is a circular steel pipe connected to the fan through a plastic hose 200. When the fan is working, the oil smoke is drawn away through the oil smoke gathering area 12-grid hole 9-grid hole duct 4-wall hole 10-main air duct 3-smoke guide hole 11-exhaust duct 2-plastic hose 200, thereby forming a negative pressure near the grid hole 9 in the oil smoke gathering area 12, thereby drawing away the oil smoke generated during the coloring process.
[0039] In order to maintain the temperature of the system during operation, the air duct system and the space of the housing 100 are filled with heat insulating material 5 .
[0040] The two inclined smoke baffles 8 are respectively fixed to the upper surface of the housing 100 by the smoke baffle adjusting screws 6, and are located above the upper opening of the oil smoke collection area 12, so as to play the role of smoke blocking. In order to stabilize the temperature in the color box at low temperatures in winter, the smoke baffle adjusting screws 6 can be loosened when the outside temperature is low to reduce the gap between the two smoke baffles 8.
[0041] like Figure 3 As shown:
[0042] Inside the color development box smoke exhaust device, the exhaust duct 2 is only half the length of the main duct 3, which can reduce the exhaust distance of the main duct 3, make the pressure loss in each area of the grid hole duct 4 tend to be consistent, and make the temperature field in the color development box more uniform, which is conducive to the color development work.
[0043] like Figure 4 As shown:
[0044] The coloring box in the figure is relatively long (3.2m or 5.6m), and the exhaust duct 2 is composed of an upper exhaust duct 21 and a lower exhaust duct 22 which are interconnected. The lengths of the upper exhaust duct 21 and the lower exhaust duct 22 are only half of the main duct 3, respectively. This can reduce the exhaust distance of the main duct 3, make the pressure loss in each area of the grid hole duct 4 tend to be consistent, and make the temperature field in the coloring box more uniform, which is beneficial to the coloring work.
[0045] like Figure 5 As shown:
[0046] Two smoke guide holes 11 are distributed at the end of the exhaust duct 2 , and the smoke guide holes 11 connect the exhaust duct 2 and the main air duct 3 . The airflow of the main air duct 3 enters the exhaust duct 2 through the two smoke guide holes 11 of the exhaust duct 2 .
[0047] like Figure 6 As shown:
[0048] In order to effectively extract the oil smoke generated during color development, a number of small holes, namely grid holes 9, are opened on the wall of the grid hole air duct 4 according to a certain pattern. The grid holes 9 connect the oil smoke collection area 12 and the grid hole air duct 4. When the color development box exhaust device is working, the oil smoke enters the grid hole air duct 4 through the grid holes 9.
[0049] In the grid hole air duct 4, n-1 partition plates 1 divide the grid hole air duct 4 into n independent parts (according to the length of the color box, the grid hole air duct 4 can be divided into several independent parts according to actual conditions. In the figure, 5 partition plates 1 divide the grid hole air duct 4 into 6 independent grid hole air ducts 4), and each independent grid hole air duct 4 has a wall hole 10, which connects the grid hole air duct 4 and the main air duct 3.
[0050] In this way, the oil smoke drawn from the vicinity of the grid hole 9 enters different areas of the grid hole air duct 4, thereby preventing the airflows in different areas from interfering with each other to form turbulence, which causes the oil smoke to be unable to be completely discharged. The oil smoke drawn from each area of the grid hole air duct 4 enters the main air duct 3 through the corresponding wall holes 19, and then enters the exhaust air duct 2 through the smoke guide hole 10, thereby extracting the oil smoke.
