Detailed Description
The utility model is further described with reference to the following drawings and specific examples, which are not intended to be limiting.
Referring to fig. 1-3, a vacuum breaking device, wherein the vacuum breaking device 1 is arranged on a charging barrel 2; the vacuum breaking device 1 comprises a vacuum breaking pipe 3, one end of the vacuum breaking pipe 3 is connected with an air suction pipe 4, the air suction pipe 4 is connected with a fan, the other end of the vacuum breaking pipe is provided with a vacuum breaking pipe baffle 5, and a plurality of air supplementing openings 6 are arranged on the vacuum breaking plate baffle. An air cylinder 7 is arranged in the vacuum breaking pipe 3, one end of the air cylinder 7 penetrates through the vacuum breaking pipe baffle 5 to enter the vacuum breaking pipe 3, and an air suction opening baffle 8 fixedly connected is arranged at one end of the air cylinder 7 entering the vacuum breaking pipe 3, so that the air cylinder 7 drives the air suction opening baffle 8 to move together; and the air cylinder 7 is sleeved with an air supplementing opening baffle plate 9, and the air supplementing opening baffle plate 9 is positioned between the vacuum tube breaking baffle plate 5 and the air suction opening baffle plate 8, so that the air supplementing opening baffle plate 9 is sleeved on the air cylinder 7 to reciprocate. In addition, be connected with spring 10 between inlet scoop baffle 9 and the inlet scoop baffle 8, when the mouth of pipe contact of inlet scoop baffle 8 and aspiration channel 4, and when inlet scoop baffle 9 and broken vacuum tube baffle 5 contact, spring 10 of connecting inlet scoop baffle 8 and inlet scoop baffle 9 is in natural state, through the effect of spring 10 and atmospheric pressure, helps inlet scoop baffle 9 to accomplish the action of opening and airtight inlet scoop 6, simple structure, it is also easier to use and maintain.
Furthermore, the vacuum breaking pipe 3 and the charging barrel 2 are partially intersected, the intersected parts are communicated through the opening 11, and the opening 11 is positioned between the vacuum breaking pipe baffle 5 and the air suction pipe 4, so that the air pressure of the vacuum breaking pipe 3 and the air pressure of the charging barrel 2 are kept consistent.
Furthermore, the radius of the inlet scoop baffle 8 is larger than that of the inlet scoop 4, so as to ensure that the inlet scoop baffle 8 can block the mouth of the inlet scoop 4 and avoid air leakage.
Furthermore, the air supply ports 6 are all located in the coverage range of the air supply port baffle plates 9, so that the air supply port baffle plates 9 can block all the air supply ports 6, and air leakage is avoided.
Furthermore, one end of the vacuum breaking pipe 3, which is far away from the air suction pipe, is communicated with the outside, so that after the material suction is completed, pressure difference exists between two sides of the air supply opening baffle plate 9, specifically, negative pressure in the vacuum breaking pipe 3 is arranged on one side, and atmospheric pressure communicated with the outside is arranged on the other side. At this time, the air supply opening baffle 9 is opened under the action of atmospheric pressure, and air rapidly enters the charging basket to balance the internal and external air pressure.
Further, the charging barrel 2 is also provided with a feeding pipe 12 and a discharging plate 13, wherein the discharging plate 13 is positioned at the lower end of the charging barrel 2, and when the fan generates negative pressure, the discharging plate 13 is in a suction state; the air suction opening is closed, and the air pressure in the charging basket is the same as the outside, the discharging plate 13 is opened.
The specific implementation process is as follows:
during normal work, the fan generates negative pressure, the air cylinder 7 drives the air suction opening baffle 8 to be far away from the air suction pipe 4, the pipe orifice of the air suction pipe 4 is opened, the discharging plate 13 is in a suction state, and the raw materials are sucked into the charging basket by the negative pressure. In the process, the spring 10 is in a compressed state, and the air supply opening baffle plate 9 covers the air supply opening 6, so that the effect of no air leakage is achieved.
