Description

A kind of hot melt tool

Technical field

The utility model relates to a kind of hot melt tool, especially relates to the adjustable hot melt tool of distance between a kind of soldering tip.

Background technology

At present, in the plastic cement products Assembling Production, the application of hot-melt technology very extensive, mainly contain hot melt and bury technologies such as nut, hot melt reference column underground, the design of hot melt tool plays important effect to the effect of hot melt, and the effect of hot melt also has direct relation to the total quality of plastic cement products.

The principle of fuse machine welding reference column is: by heating platen soldering tip is heated up, when soldering tip was descending, the temperature of soldering tip was melted the reference column on the plastic cement products, soldering tip is pressed on the reference column of thawing, make its moulding and cooled and solidified, the part that is contained on the product is fixed.

The principle of fuse machine welded nut is: earlier nut is placed in the nut bore on the product, soldering tip heats up by heating platen, when soldering tip is descending, the temperature of soldering tip makes the nut bore on the plastic cement products because of being heated the plastic cement around it be melted, soldering tip is descending simultaneously, nut is pressed in the nut bore of product, the up nut that leaves of soldering tip then, plastic rubber shaping cooling back nut is fixed in the nut bore of product.

By above-mentioned principle as can be seen, hot melting process requires very high to the fixed position of soldering tip, the soldering tip of hot melt tool commonly used is few two post positions, reach most 23 post positions, the correctly contraposition of each soldering tip, and all soldering tips must same horizontal level or with the height unanimity of the different welding points of product, to guarantee the quality of welding nut or reference column.In enclose utility model patent 200520072664.5 specifications and disclose a kind of hot melt tool, soldering tip is fixed on the base plate (heating platen) by the screw thread of its root, its level all can not be regulated with vertical position.If the soldering tip of hot melt tool does not reach positioning requirements, size is deviation slightly, will produce position deviation and phenomenon such as highly inconsistent during hot melt, particularly torsion, the pulling capacity generations such as (examination criterias of using always in the hot melt nut technology) of nut have a strong impact on to product quality, and in adjustment process, can only rely on accent machine technology person's experience, utilize means such as beat gently to make soldering tip slightly change the position, precision is difficult to control, and soldering tip is because bending, disconnected post etc. can appear in the cause of knocking, cause adjusting machine time long, influence ordinary production.

The utility model content

The technical problems to be solved in the utility model provides the hot melt tool of the distance between a kind of conveniently adjusted soldering tip.

For solving the problems of the technologies described above, a kind of hot melt tool of the utility model comprises base plate and the soldering tip with spiro rod section, and wherein, it also comprises adjusts piece and adjust bolt; The spiro rod section of described soldering tip is screwed onto on this adjustment piece; Offer the adjustment hole that forms matched in clearance with the screw rod of this adjustment bolt on this adjustment piece, the screw rod end of this adjustment bolt passes this adjustment hole and is screwed onto on the described base plate, will adjust the piece locking on this base plate.

As a kind of improvement of the present utility model, in above-mentioned basis, wherein, the cross section ovalize in described adjustment hole.

As a kind of improvement of the present utility model, in above-mentioned basis, wherein, described adjustment hole is parallel to described soldering tip.

As a kind of improvement of the present utility model, in above-mentioned basis, wherein, be bolted with clamp nut on the spiro rod section of described soldering tip, this clamp nut is locked at this soldering tip on this adjustment piece after this spiro rod section is screwed onto on this adjustment piece.

As a kind of improvement of the present utility model, in above-mentioned basis, wherein, begin to have several and described adjustment bolt to form the screw of threaded engagement on the described base plate.

The utility model compared with prior art, a kind of hot melt tool of the utility model, because soldering tip is fixed on the base plate by adjusting piece, promptly adjust the adjustment hole that the screw rod that offers and adjust bolt on the piece forms matched in clearance, the screw rod end of adjusting bolt passes the adjustment hole and is screwed onto on the base plate, will adjust the piece locking on base plate.When needing to adjust the horizontal level of soldering tip, unscrew the adjustment bolt, it is the center rotation that the adjustment piece promptly can be adjusted bolt, can move along adjusting the hole relative to this adjustment bolt again, after adjusting the horizontal level of soldering tip, screw this adjustment bolt, will adjust piece and be fixed on the base plate, therefore the utility model can be adjusted the horizontal level of soldering tip easily, and is simple in structure.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is further described.

Fig. 1 is the perspective view of a kind of hot melt tool of the utility model.

Fig. 2 is the main TV structure schematic diagram of a kind of hot melt tool of the utility model.
