Foam machine head

technical field

The utility model relates to a gun head, in particular to a gun head of a foaming machine.

Background technique

Referring to Fig. 1, 2, the existing foaming machine comprises a first gun barrel 111 that outputs a kind of first chemical medicament, a second gun barrel 121 that outputs a kind of second chemical medicament, and a A gun barrel 111 and a gun head connected to the second gun barrel 121, the first chemical agent and the second chemical agent are mixed in the gun head to form a foam material that can be used for packaging and then output, and used after use A detergent for cleaning.

Specifically, the gun head of the conventional foaming machine includes a gun head body 14 and a gun shaft 15 .

The gun head body 14 includes a mixing tank 141 passing through the gun head body 14 axially, a first feeding channel 142 , and a second feeding channel 143 . The mixing tank 141 has a spray port 144 , a base port 145 opposite to the spray port 144 , and a cleaning agent feed channel 140 .

The first feed channel 142 has a first feed port 146 located between the ejection port 144 and the base port 145 and communicated with the mixing tank 141, and a first feed port 146 opposite to the first feed port 146 and detachably connected to the first feed port 146. The first connection port 147 to which the first gun barrel 111 is connected. The first chemical agent can flow into the mixing tank 141 from the first barrel 111 through the first connecting port 147 and the first feeding port 146 .

The second feed channel 143 has a second feed port 148 located between the ejection port 144 and the base port 145 and communicated with the mixing tank 141, and a detachable ground opposite to the second feed port 148. The second connection port 149 connected with the second gun barrel 121 . The second chemical agent can flow into the mixing tank 141 from the second barrel 121 through the second connecting port 149 and the second feeding port 148 .

The cleaning agent feeding channel 140 passes through the gun head body 14 corresponding to the ejection port 144 from the outside, for injecting the cleaning agent when cleaning the gun head body 14 , please continue this part later.

The gun shaft 15 includes a gun shaft body 151 that extends from the mixing tank 141 and can slide along the mixing tank 141, and a gun shaft body 151 that is connected to the front end of the gun shaft body 151 and can be driven by the gun shaft body 151 to make the spray Outlet 144 , the first feed port 146 and the second feed port 148 any one of which is closed and opened block 152 , and a drive 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 so that the closing block 152 is at a feed position and a Move between closed positions, and when the closed block 152 is in the feeding position, the closed block 152 is relatively close to the base port 145, so that the first chemical agent passes through the first connection port 147 from the first gun barrel 111 And the first feeding port 146 flows into the mixing tank 141, and the second chemical agent flows into the mixing tank 141 through the second connection port 149 and the second feeding port 148 from the second gun barrel 121, so that The first chemical agent and the second chemical agent are mixed, and at the same time, the mixed first chemical agent and the second chemical agent are sprayed out from the ejection port 144 to form a foam material for packaging.

After the required foaming material is sufficient, push the closing block 152 to be positioned at the closed position. At this moment, the driving block 153 drives the gun shaft body 151 to move toward the ejection port 144, so that the closing block 152 is exposed on the spraying port. Out of the outlet 144, and make the ejection port 144, the first feed port 146 and the second feed port 148 in a closed state, so that the first chemical agent and the second chemical agent cannot continue to enter the mixing tank 141 At the same time, the ejection port 144 no longer outputs the mixed first chemical agent and the second chemical agent.

The gun head of the existing foaming machine can indeed connect the first gun barrel 111 and the second gun barrel 121, so that the first chemical agent and the second chemical agent can be mixed in the gun head to be used for packaging After the foam material is exported.

Referring to Fig. 3, but, when the existing gun head needs to be cleaned after use, a cleaning cover 16 must be sleeved on the gun head body 14, wherein, the cleaning cover 16 includes a nozzle for housing the gun head body 14. The cleaning space 161 of the outlet 144, and a cleaning agent injection channel 162 for injecting the cleaning agent, and allowing the cleaning agent to fill the cleaning space 161 from the cleaning agent injection channel 162 through the cleaning agent feeding channel 140 Only in this way can the front end of the gun head body 14, especially the outlet 144, be soaked with the cleaning agent to complete the cleaning of the gun head. In addition to adding the cleaning cover 16 during this process to increase the operation process, since the gun head body 14 of the existing gun head is funnel-shaped and concave toward the base port 145, the cleaning agent Even if the entire cleaning space 161 is completely filled, it is difficult to clean the gun head body 14 completely.

Therefore, the gun head of the existing foaming machine needs to be improved to improve the convenience of operation and cleaning by the staff.

The first feed channel 52 has a first feed port 521 located between the ejection port 511 and the base port 512 and communicated with the mixing tank 51, and a detachable ground opposite to the first feed port 521. The first connecting port 522 connected with the first gun barrel 21 . The first chemical agent flows into the mixing tank 51 from the first barrel 21 through the first connecting port 522 and the first feeding port 521 .

The second feed channel 53 has a second feed port 531 located between the ejection port 511 and the base port 512 and communicated with the mixing tank 51 , and a detachably opposite to the second feed port 531 . The second connection port 532 connected with the second gun barrel 31 . The second chemical agent flows into the mixing tank 51 from the second barrel 31 through the second connecting port 532 and the second feeding port 531 .

The nozzle 6 is connected with the gun head body 5 and includes a nozzle body 61, and a nozzle outer wall 62 extending outwards from the nozzle body 61 in an arc concave manner, the nozzle outer wall 62 is connected with the nozzle body 61 and defines a cleaning Space 63, the nozzle body 61 has a cleaning agent inlet 611 communicating with the cleaning space 63, and a cleaning agent connection port opposite to the cleaning agent inlet 611 and detachably connected to the cleaning gun barrel 41 612 , the nozzle outer wall 62 has a nozzle open end 631 corresponding to the ejection port 511 .

The gun shaft 7 includes a gun shaft body 71 that extends from the mixing tank 51 and can slide along the mixing tank 51, and a gun shaft body 71 that is connected to the front end of the gun shaft body 71 and can be driven by the gun shaft body 71 to make the nozzle The open end 631 , the ejection port 511 , the first feed port 521 and the second feed port 531 are any one of the closed block 72 that is closed and opened, and the drive block 73 connected to the rear end of the gun shaft body 71 .

The driving block 73 drives the gun shaft body 71 and the closing block 72 so that the closing block 72 is at a feeding position and a Move between closed positions, and when the closed block 72 is in the feeding position, the closed block 72 is relatively close to the base port 512, so that the first chemical agent is passed from the first gun barrel 21 through the first connecting port 522 and The first feeding port 521 flows into the mixing tank 51, and the second chemical agent flows into the mixing tank 51 from the second gun barrel 31 through the second connection port 532 and the second feeding port 531, so that the The first chemical agent and the second chemical agent are mixed, and at the same time, the mixed first chemical agent and the second chemical agent are sprayed out from the ejection port 511 to form a foam material for packaging.
