Problems solved by technology

[0004] In view of the above-mentioned related technologies, when coating the material, the spray gun sprays the material upwards, and at the same time, the coating medium supply device sprays the coating medium on the blown material, and the coating medium immediately covers the surface of the material; after that, After the coating medium is dried by the hot air device, a complete coating layer is formed on the surface of the material; the inventor believes that when using the above-mentioned coating machine for coating operations, the suspension time of the material in the coating pan depends on the amount of time the material is sprayed from the spray gun. However, due to the different bonding speeds of materials and corresponding coating media, the time that materials need to be in contact with coating media is also different; when the above coating machine coats materials, the materials are in the coating pan. The length of the suspension time is relatively simple, the applicability is poor, and there is room for improvement

Embodiment 1

[0047] refer to figure 1 and figure 2 , a kind of barrel body for coating, which is installed on the lower side of the pan 31 of the coating machine, and is used to blow the material in the pan 31 upward into the coating barrel 3, so that the material and the coating barrel 3 The suspended coating medium sticks and forms a coating layer. Including an air intake bucket 1, the air intake bucket 1 includes an outer cylinder 11 communicated with the material holding tray 31, and an inner cylinder 12 embedded in the outer cylinder; the air inlet of the inner cylinder 12 is communicated with a first frequency conversion fan 114, and the outer cylinder 11 The air inlet of cylinder 11 is connected with a second frequency conversion fan 115; at the same time, according to the difference in the distance between the rising path and falling path of different materials, an extension pipe 15 is connected between the inner cylinder 12 and the material holding tray 31, and the outer cylinde...

Embodiment 2

[0058] refer to Figure 7 , a coating machine, comprising the bucket body in Embodiment 1, the coating machine also includes a control cabinet 2, and a coating bucket 3 hinged on one side of the control cabinet 2 in the horizontal direction, and the coating bucket 3 is installed on the side wall There is a feeding device 32 for spraying the coating medium; the air inlet barrel 1 is detachably fixed on the lower side of the coating barrel 3, and the air inlet barrel 1 is connected to the coating barrel 3; the first frequency conversion fan 114, the second frequency conversion fan Fans 115 are all installed in the control cabinet 2, and the air outlets of the first frequency conversion fan 114 and the second frequency conversion fan 115 are connected with ventilation pipes 17, and any ventilation pipe 17 extends out of the control cabinet 2 and communicates with the corresponding first air flow respectively. chamber 1111 and the second air chamber 1112 . At the same time, a hea...

Abstract

The invention discloses a barrel body for coating, and relates to the technical field of coating equipment. The barrel body comprises an air inlet barrel, a first air duct and a second air duct are arranged in the air inlet barrel, and the first air duct and the second air duct are both communicated with a material containing disc for containing materials; the air inlets of the first air duct and the second air duct are respectively connected with a first frequency conversion fan and a second frequency conversion fan. Materials are blown upwards by the aid of the first air duct and the first variable-frequency fan, so that the materials rise and then fall in the coating barrel along the parabolic trajectory, upward thrust is provided for the falling materials by the aid of the second air duct and the second variable-frequency fan, and the materials can be uniformly coated by adjusting the air outlet speeds of the first variable-frequency fan and the second variable-frequency fan. The effect of adjusting the suspension time of the materials in the coating barrel is achieved, the application range of the coating machine is effectively widened, and the practicability of the coating machine is improved.

Description

technical field [0001] The present application relates to the technical field of coating equipment, in particular to a barrel for coating and a coating machine using the barrel. Background technique [0002] In industrial production, a vertical coating machine is usually used to coat Chinese and Western medicine tablets, pills, and candies with sugar coating, aqueous phase film, and organic film coating process. [0003] The traditional vertical coating machine usually includes a coating pot for coating operation, the upper end of the coating pot is connected with an exhaust device, and a coating medium supply device is arranged in the coating pot; the lower side of the coating pot Connected with a material driving device, the material driving device is connected with a spray gun, and the nozzle of the spray gun faces the opening of the coating pot; a hot air device is installed on the coating pot, and the material driving device and the coating medium supply device are loca...
