Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Refer to Figures 1-4 , the present utility model provides two technical solutions:

[0025] The first implementation manner: A glue spraying device with a glue nozzle anti-drip structure includes a fixed cylinder 1. A nozzle mechanism 2 is arranged outside the fixed cylinder 1 for spraying glue on the mouth strip. The nozzle mechanism 2 includes:

[0026] The glue spraying assembly 21 is arranged outside the fixed cylinder 1 for facilitating glue spraying on the edge strip. A fixed nozzle 217 is fixedly installed on the top surface of the fixed cylinder 1;

[0027] The anti - dripping assembly 22 is arranged on the top surface of the fixed nozzle 217 for preventing the glue adhered to the top surface of the fixed nozzle 217 from dripping. The anti - dripping assembly 22 includes a retaining cylinder 221 fixedly installed on the top surface of the fixed nozzle 217. A circular groove 223 is formed inside the retaining cylinder 221. A number of glue suction holes 222 are formed on the inner side of the retaining cylinder 221, and a number of glue suction holes 222 are inclined. A number of glue suction holes 222 are evenly distributed in a circumferential direction on the inner side of the retaining cylinder 221. A number of connecting pipes 224 are fixedly installed on the outer side of the retaining cylinder 221, and a number of connecting pipes 224 are evenly distributed in a circumferential direction on the outer side of the retaining cylinder 221. One end of a number of connecting pipes 224 is fixedly installed with an annular pipe 225. An air pipe 226 is fixedly installed on the right side of the annular pipe 225. One end of a number of glue suction holes 222 all penetrate through the inner side of the retaining cylinder 221 and extend into the interior of the circular groove 223. One end of a number of connecting pipes 224 away from the annular pipe 225 all penetrate through the outer side of the retaining cylinder 221 and extend into the interior of the circular groove 223. One end of a number of connecting pipes 224 close to the annular pipe 225 all penetrate through the outer side of the annular pipe 225 and extend into the interior of the annular pipe 225.

[0028] By providing the glue suction holes 222 and the annular pipe 225, the glue of the device can be prevented from dropping on the workbench. During use, one end of the air pipe 226 is connected to the input end of a high - viscosity pump. When the device finishes glue spraying, the high - viscosity pump is started to suck air through the air pipe 226. At this time, the glue will be sucked into the interior of the circular groove 223 through the glue suction holes 222, and then sucked from the interior of the circular groove 223 to the interior of the annular pipe 225 through the connecting pipes 224, and then discharged to the outside through the air pipe 226, which is convenient for cleaning the residual glue, avoids the glue falling on the workbench and affecting the working environment, and has good practicability.

[0029] The second implementation mode, the main difference from the first implementation mode is that: the glue spraying assembly 21 further includes an annular groove 219 opened on the bottom surface of the fixed cylinder 1. A fixed ring 2110 is movably installed inside the annular groove 219. The bottom surface of the fixed ring 2110 is fixedly installed with an installation cylinder 211. Thread lines 212 are provided on the inner side of the installation cylinder 211. A conical groove 215 is opened on the bottom surface of the fixed nozzle 217, and the bottom surface of the conical groove 215 is arc-shaped. A connection groove 216 is opened inside the fixed nozzle 217. The top surface of the inner cavity of the fixed cylinder 1 is fixedly installed with a connection cylinder 214. A sealing ring 213 is fixedly installed on the bottom surface of the connection cylinder 214, and the sealing performance of the device connected to the glue gun can be improved through the sealing ring 213. A glue spraying groove 218 is opened on the top surface of the fixed nozzle 217, and both the top end and the bottom end of the glue spraying groove 218 are funnel-shaped. The bottom surface of the fixed ring 2110 movably penetrates through the inside of the annular groove 219 and is fixedly installed on the top surface of the installation cylinder 211. The top surface of the connection cylinder 214 penetrates through the inside of the fixed cylinder 1 and extends to the top surface of the fixed cylinder 1. The bottom surface of the glue spraying groove 218 penetrates through the top surface of the fixed nozzle 217 and extends into the connection groove 216. The top surface of the conical groove 215 penetrates through the bottom surface of the fixed nozzle 217 and extends into the connection groove 216.

[0030] The thread lines 212 and the sealing ring 213 facilitate the disassembly and cleaning of the device. When cleaning is required, rotating the thread lines 212 can drive the fixed cylinder 1 to be removed from the glue spraying pipe. After cleaning, the thread lines 212 are sleeved on the outside of the glue spraying pipe, and then rotating the thread lines 212 drives the fixed cylinder 1 to move downward. Then the sealing ring 213 will abut against the pipe orifice of the glue spraying pipe, and then stop rotating the thread lines 212 to fix the position of the fixed cylinder 1. When the glue gun is started, the glue can enter the inside of the connection cylinder 214, avoiding the glue flowing to the outside, improving the sealing performance of the device, and being convenient for disassembly and cleaning.

[0031] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0032] In use, the user puts the threaded wire 212 on the outside of the glue spraying tube, then rotates the threaded wire 212 to drive the fixing cylinder 1 to move downward. Then the sealing ring 213 will abut against the nozzle of the glue spraying tube. At this time, stop rotating the threaded wire 212 to fix the position of the fixing cylinder 1. Then connect one end of the air tube 226 to the input end of the high-viscosity pump. Then start the spray gun, and the glue will enter the inside of the conical groove 215 through the connecting cylinder 214, and then spray out from the glue spraying groove 218 through the connecting groove 216 to spray the butt strip. After the spraying is completed, turn off the spray gun. At this time, part of the glue will be on the top surface of the fixed nozzle 217 inside the mounting cylinder 211. While turning off the spray gun to stop glue spraying, start the high-viscosity pump to suck air through the air tube 226. At this time, the glue will be sucked into the inside of the circular groove 223 through the glue suction hole 222, and then be sucked from the inside of the circular groove 223 to the inside of the annular tube 225 through the connecting pipe 224, and then discharged to the outside through the air tube 226, which is convenient for cleaning the residual glue.
