Problems solved by technology
The speed of ZL26C molding machine is fast, reaching 600 meters per minute. If the seal in the glue gun is damaged, it will definitely cause glue leakage, which will cause the glue sprayed on the molding paper to be intermittent, causing the paper edge to be not bonded firmly, and filter Rod burst quality defects
The sealing parts of the hot melt glue gun of the existing ZL26C filter rod forming machine are all heat-resistant rubber parts, and the thinner part in the middle will move with the reciprocating movement of the spray needle, which is easily damaged, often causing the glue to leak from the hot melt glue chamber (like figure 1 shown)
Due to the short service life of heat-resistant rubber seals, frequent replacement of seals and large consumption of spare parts
The existing improvement measures are mainly to change the heat-resistant rubber material to brass material, but there is a gap between the brass and the spray needle, and the hot melt glue is easy to leak from the gap

The invention discloses a combined seal used for a hot-melt glue gun of a filter rod forming machine. The hot-melt glue gun includes a glue gun seat (1), a nozzle body (2), an intermediate body (3), and a cylinder body (4), spray needle (5), combined seal (6), characterized in that: the combined seal (6) includes a seal seat (61), a seal body (62), a pressure plate (63), a seal The flange edge of the seat is installed in the corresponding glue gun seat installation groove of the glue gun seat, the sealing body is installed in the inner hole of the seal seat, and the end of the seal seat close to the cylinder body is provided with a pressure plate groove (67), the pressure plate groove A pressure plate is arranged inside. It can automatically compensate the amount of wear and keep the sealing of the worn heat-resistant rubber material; even in the case of leakage, the leaked hot melt adhesive can only flow from the annular groove to the hot melt adhesive chamber, thereby avoiding Possibility of hot melt adhesive leaking into the intermediate.
Description
technical field [0001] The invention relates to the technical field of coiling auxiliary equipment used in the tobacco industry, in particular to a combined seal used for a hot melt glue gun of a filter rod forming machine. Background technique [0002] ZL26C filter rod forming machine hot melt glue gun principle structure is as follows: figure 1 As shown, when working, the glue pump pumps the hot-melt glue liquid into the hot-melt glue chamber of the glue gun, and at the same time, the compressed air enters the cylinder, driving the spray needle to move to the right, the glue liquid flows out through the nozzle body, and sprays on the edge of the forming paper. Glue the two paper edges together when the filter rod is formed. When the glue pump is not working (such as figure 1 As shown), the compressed air releases the pressure, and the compression spring pushes the spray needle against the glue outlet of the nozzle body to prevent the glue from flowing out. The speed of ...
