Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

Fig. 1 is the structure schematic diagram of the utility model, fig. 2 is the structure schematic diagram of the utility model when the shutoff holds the case entry.

The utility model provides a can backward flow type hot melt adhesive rifle, includes the rifle body 1, excellent chamber cover 2, switch trigger 3, hot melt pipe 4 and rifle mouth 5, and the barrel internal fixation of rifle body 1 has excellent chamber cover 2 and hot melt pipe 4, and the barrel exit of rifle body 1 is fixed with rifle mouth 5, and swing joint has switch trigger 3 on the rifle body 1, switch trigger 3 is fixed in plate body 6 one side, and the opposite side that plate body 6 is relative is arranged in and is held case 7, and plate body 6 is connected with holding case 7 sliding fit, and holding case 7 is fixed on rifle body 1, and rifle mouth 5 is the cone-shaped mouth, and the junction of hot melt pipe 4 and rifle mouth 5 is linked together with the entry of holding case 7, and the sliding fit is connected with the shutoff piece 8 that is used for sealing to hold the case 7 entry in holding case 7, and shutoff piece 8 is articulated with bull stick 9 one end, and the bull stick 9 other end is articulated with plate body 6, and the body of rod of bull stick rotation of bull stick. A spring 10 is connected between the plugging block 8 and the bearing box 7. The receiving box 7 is a cylindrical box body. The bottom opening of the receiving box 7 is in threaded connection with the circular cover plate 11. The joint of the hot melting pipe 4 and the gun nozzle 5 is communicated with the inlet of the receiving box 7 through a pipe body 12.

The working method of the hot melt adhesive gun is that, the adhesive tape is inserted into the hot melt pipe 4 through the adhesive stick cavity sleeve 2, at the moment, the switch trigger 3 is pulled, so that the control chip is triggered to start the power supply to be electrified, the power supply heats the thermistor attached to the hot melt pipe 4 in an electrified way, the adhesive stick inside is heated and dissolved through the hot melt pipe 4, and finally, the gun nozzle 5 flows out to perform bonding operation.

When the switch trigger 3 is pushed, the plate body 6 moves linearly and horizontally rearward along the notch of the receiving box 7 engaged therewith, as shown in fig. 2. Bearing case 7 internal fixation has the axostylus axostyle, and this axostylus axostyle passes the shaft hole on the bull stick 9 and realizes rotating the connection, and 6 pulling bull sticks 9 lower extremes of plate body that move backward turn left swing, and the upper end of bull stick 9 will turn right swing this moment, and the upper end of bull stick 9 will promote the shutoff piece 8 and turn right and move to plug up the entry of bearing case 7. The spring 10 is now in tension. At this time, the glue can be used normally without flowing into the receiving box 7.

As shown in figure 1, after the switch trigger 3 is released, the blocking block 8 is pulled to slide reversely under the driving of the resilience of the spring 10 after restoring the deformation, so that the inlet of the receiving box 7 is opened, and the residual glue solution flows down along the inclined plane and flows into the receiving box 7 through the pipe body 12 because the gun nozzle 5 is a conical nozzle. This prevents the residual glue from flowing out of the nozzle 5 or back into the thermofusion tube 4.

When the residual glue in the receiving box 7 needs to be cleaned, the glue can be poured out from the opening at the bottom of the receiving box 7 only by unscrewing the cover plate 11.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
