Foam head

The present invention relates to a pipe head, and more particularly to a pipe head of a foaming machine.

Referring to Figures 1 and 2, the prior art foaming machine includes a first barrel 111 for outputting a first chemical 11 , a second barrel 121 for outputting a second chemical 12 , and a first barrel 111 and the second barrel 121 connected to the gun head 1, the first chemical agent 11 and the second chemical agent 12 are mixed in the gun head 1 to be used as a foaming material for packaging, and after use, Use a cleaning agent 13 to clean.

In detail, the tip 1 of the prior foaming machine includes a tip body 14 and a gun shaft 15.

The tip body 14 includes a mixing groove 141 that axially passes through the tip body 14, a first feed channel 142, and a second feed channel 143. The mixing tank 141 has a discharge port 144, a base port 145 opposite to the discharge port 144, and a cleaning agent feed channel 140.

The first feed channel 142 has a first feed port 146 between the discharge port 144 and the base port 145 and communicates with the mixing groove 141, and a detachable contact with the first feed port 146 And the first barrel 111 The first connection port 147 is connected. The first chemical agent 11 can flow into the mixing tank 141 from the first barrel 111 through the first connection port 147 and the first inlet port 146.

The second feed channel 143 has a second feed port 148 located between the discharge port 144 and the base port 145 and communicating with the mixing groove 141, and is detachable from the second feed port 148. A second connection port 149 connected to the second barrel 121. The second chemical 12 can flow from the second barrel 121 through the second connection port 149 and the second inlet 148 into the mixing tank 141.

The cleaning agent feeding channel 140 passes through the nozzle body 14 from the outside corresponding to the nozzle outlet 140 for injecting the cleaning agent 13 when cleaning the tip body 14. This part is to be continued later.

The gun shaft 15 includes a gun shaft body 151 extending along the mixing groove 141 and sliding along the mixing groove 141. A gun shaft body 151 is coupled to the front end of the gun shaft body 151 and can be driven by the gun shaft body 151 to make the spray port. 144. The first feeding port 146 and the second feeding port 147 are closed and opened by one of the closing blocks 152, and a driving block 153 connected to the rear end of the gun shaft body 151.

The driving block 153 drives the gun shaft body 151 and the closing block 152 to make the closing block 152 relative to the first feeding port 146, the second feeding port 147 and the ejection port 144 at a feeding position and a Moving between closed positions; and when the blocking block 152 is in the feeding position, the closing block 152 is relatively close to the base opening 145, and the first chemical agent 11 is passed by the first barrel 111 through the first connecting port 147 and the first feed port 146 flows into the mix The first syrup 141, and the second chemical agent 12 flow from the second barrel 121 through the second connection port 149 and the second inlet port 148 into the mixing tank 141, thereby allowing the first chemical agent 11 and the first The two chemical agents 12 are mixed, and the mixed first chemical agent 11 and the second chemical agent 12 are ejected from the ejection port 144 to form a foamed material for packaging.

When the required foaming material is sufficient, the closing block 152 is pushed in the closed position. At this time, the driving block 153 drives the gun shaft body 151 to move toward the discharge port 144, so that the closing block 152 is exposed to the spray. The outlet 144 is outside, and the discharge port 144, the first inlet port 146 and the second inlet port 147 are closed, so that the first chemical agent 11 and the second chemical agent 12 cannot continue to enter the mixture. In the tank 141, at the same time, the discharge port 144 does not output the mixed first chemical agent 11 and the second chemical agent 12 at the same time.

The first head tube 111 and the second barrel tube 121 of the existing foaming machine can be connected to the first barrel 111 and the second chemical agent 12 to be mixed in the gun head 1. Can be used for packaging after the foam material is output.

Referring to FIG. 3, however, when the existing tip 1 needs to be cleaned after use, a cleaning cover 16 must be sleeved on the tip body 14, wherein the cleaning cover 16 includes a spray that covers the tip body 14. a cleaning space 161 of the outlet 144, and a cleaning agent injection channel 162 for injecting the cleaning agent 13 to allow the cleaning agent 13 to be filled from the cleaning agent injection channel 162 through the cleaning agent feed channel 140. After the space 161, the cleaning agent 13 can be soaked at the front end of the tip body 14, especially at the discharge port 144. The cleaning of the tip 1 is completed. In addition to the additional operation of the cleaning cover 16 in addition to the additional operation, since the existing tip body 141 of the tip 1 is concave in the direction of the base opening 145, the cleaning is performed. It is difficult for the medicament 13 to completely clean the tip body 141 even if the entire cleaning space 161 is completely filled.

Therefore, the tip of the existing foaming machine needs to be improved to improve the convenience of the staff to operate and clean.

Therefore, the object of the present invention is to provide a nozzle for a foaming machine having a cleaning function.

Therefore, the present invention provides a nozzle of a foaming machine, the foaming machine comprising a first barrel for outputting a first chemical, a second barrel for outputting a second chemical, and a cleaning agent for discharging The barrel is cleaned, and the tip of the foaming machine comprises a tip body, a nozzle connected to the tip body, and a gun shaft extending into the body of the gun.

The tip body includes a mixing tank axially penetrating the tip body, a first feed channel, and a second feed channel, the mixing tank having a discharge port and a base port opposite to the discharge port .

The first feed item has a first feed port between the discharge port and the base port and communicating with the mixing groove, and a first feed port opposite to the first feed port and detachably and the first barrel The first connection to the connection.

The second feed item has a second feed port between the discharge port and the base port and communicating with the mixing groove, and a second feed port opposite to the second feed port and detachably and the second barrel The second connection port that is connected.
