DETAILED DESCRIPTION

[0017] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings.

[0018] Example:

[0019] Combination Figures 3 to 5 The figure shows a specific implementation of a nitrogen blowing filling head for standing bag noodle sauce of the utility model, which mainly comprises an outgoing material pipe 1, a radially contracted discharging head 1a is provided at the bottom of the outgoing material pipe 1, and a stepped right-angle portion 1b is formed at the connection between the outgoing material pipe 1 and the discharging head 1a. The outgoing material pipe 1 is used for filling the sauce.

[0020] An inner blowing pipe 2 is provided inside the outgoing material pipe 1. The bottom of the inner blowing pipe 2 is a conical head 3. The conical head 3 has a plurality of blowing holes 3a. The plurality of blowing holes 3a are arranged in two circles around the conical head 3, and the blowing holes 3a in each circle are evenly arranged.

[0021] The inner blowing pipe 2 is provided with a sealing head 4 for blocking or opening the blowing hole 3a. Figure 3 As shown, the interior of the head 4 is a hollow structure, and through holes 4a are opened on the top, bottom and side walls of the head 4. The through holes 4a and the blowing holes 3a on the side walls where the head 4 contacts the conical head 3 are staggered, so that the blowing holes 3a can be blocked when the head 4 and the conical head 3 are fitted together, and the gas can pass through the through holes 4a and blow out from the blowing holes 3a when the head 4 and the conical head 3 are separated.

[0022] A positioning piece 5 is connected to both sides of the sealing head 4, and the two positioning pieces 5 are symmetrical. Two through holes 2a are provided on the inner air blowing pipe 2 for the two positioning pieces 5 to pass through respectively. The positioning pieces 5 pass through the inner air blowing pipe 2 to the outside, and the positioning pieces 5 can move up and down in the through holes 2a. An upper sealing sliding sleeve 6 and a lower sealing sliding sleeve 7 are connected to the upper and lower sides of the two positioning pieces 5, and the upper sealing sliding sleeve 6 and the lower sealing sliding sleeve 7 are both sealed and slidably fitted with the inner wall of the inner air blowing pipe 2. When the positioning piece 5 moves up and down in the through hole 2a, the two sealing sliding sleeves can prevent gas from leaking from the through hole 2a.

[0023] The top of the end cap 4 is connected with a transmission sleeve 8, which is connected to the inner side of the upper sealing sliding sleeve 6. A chute is provided on the inner wall of the inner air blowing pipe 2, and the transmission sleeve 8 is installed in the chute by a spring 9.

[0024] The sauce is discharged from the discharge head 1a of the external feeding pipe 1 for filling. After the filling is completed, the internal blowing pipe 2 descends, and the positioning member 5 first contacts and bears on the right angle portion 1b. Figure 4As shown, the blowing pipe 2 continues to descend, the conical head 3 extends into the discharge head 1a, the sealing head 4 separates from the conical head 3, the blowing hole 3a opens, and the nitrogen in the inner blowing pipe 2 passes through the through hole 4a and blows out from the blowing hole 3a, achieving oblique blowing, and fully blowing away the residual material on the inner wall of the discharge head 1a. After the blowing is completed, the blowing pipe 2 rises and resets, and the sealing head 4 automatically closes and blocks the blowing hole 3a under the action of the spring 9, preparing for the next blowing. The action of closing the blowing hole 3a can effectively prevent the residual material from entering and affecting the next blowing, thereby improving the filling effect.
