Abstract
The utility model discloses an automatic transition apparatus for seam and seamless welding of plastic door and window welding machine, which includes known upper and lower pressure clamps, a heating plate, a lifting cylinder and a positioning plate connecting the upper side of the lifting cylinder, charactered in that the said positioning plate is a double-convex positioning plate, and a cylinder conversion cylinder also connected on the lifting cylinder. When it needs for seamless welding, the conversion cylinder does not work, the lifting cylinder drives the double-convex positioning plates to bump up, and the lower pressure clamp clamps the upper positioning plate of the double convex positioning plate, the welding gap of the jaw is smaller now, capable of welding seamlessly. When it needs for a welding seam, the conversion cylinder and the lifting cylinder work at the same time, and the lower pressure clamp clamps the lower positioning plate of the double convex positioning plate, the welding gap of the jaw is larger now, capable ofwelding with seam. The conversion cylinder is controlled by a gas way switch, which is very convenient to switch and do not need to do any adjustment of parts, accordingly can realize seam and seamless welding of plastic door and window on a straight line welding machine.

The technical scheme that the utility model is adopted for achieving the above object is:
A kind of plastic door-window welding machine has seam and no seam welding automatic transfer equipment, comprise the preceding location-plate of going up pressing tongs, heating plate, lift cylinder under pressing tongs on pressing tongs, the back, preceding pressing tongs down, the back, being connected in lift cylinder top, its special character is that described location-plate is the double polarizing keys location-plate.
Double polarizing keys location-plate of the present utility model is made up of last location-plate that is connected as a single entity and following location-plate, and the thickness of following location-plate is greater than the thickness of last location-plate.
The following location-plate of double polarizing keys location-plate of the present utility model is along the center line left-right symmetry of last location-plate.
Also be connected with the conversion cylinder on the lift cylinder of the present utility model.
Operation principle of the present utility model is as follows:
When need not have seam welding, the conversion cylinder is not worked, lift cylinder air inlet work, drive the double polarizing keys location-plate and rise, the jaw of pressing tongs is clamped in the last location-plate place of double polarizing keys location-plate under preceding pressing tongs down, the back, and the jaw welded gaps of this moment is less, be generally 0.2mm, can not have seam welding.
In the time of need seam welding being arranged, conversion cylinder and lift cylinder are worked simultaneously, drive the double polarizing keys location-plate and rise, the jaw of pressing tongs is clamped in the following location-plate place of double polarizing keys location-plate under preceding pressing tongs down, the back, the jaw welded gaps of this moment is bigger, is generally 2mm, and seam welding can be arranged.
The lifting of conversion cylinder control by an air circuit breaker, changes very conveniently, does not need any part is adjusted, and just can realize on a straight line bonding machine that plastic door-window is had seam welding and no seam welding.Its concrete operation principle, job step have seam straight line bonding machine identical with seamless straight line bonding machine with single functional plastics door and window of prior art.
Description of drawings
Fig. 1 is that plastic door-window welding machine of the present utility model has seam and no seam welding automatic transfer equipment not to have the schematic diagram of seam welding.
Fig. 2 is that plastic door-window welding machine of the present utility model has seam and no seam welding automatic transfer equipment that the schematic diagram of seam welding is arranged.
Among the figure: the 1-frame, 2-changes cylinder, following pressing tongs behind the 3-, section bar behind the 4-is gone up pressing tongs behind the 5-, the last pressing tongs cylinder of 6-is gone up pressing tongs, the last location-plate of 9-, 10-limit section bar before the 7-heating plate, 8-, pressing tongs under before the 11-, location-plate under the 12-, 13-lift cylinder, 14-heating plate cylinder.
The specific embodiment
Fig. 1, the plastic door-window welding machine that Figure 2 shows that a kind of specific embodiment of the present utility model have seam and no seam welding automatic transfer equipment, it comprises the known preceding location-plate of going up pressing tongs 3, heating plate 7, lift cylinder 13 under pressing tongs 5 on pressing tongs 8, the back, preceding pressing tongs 11 down, the back, being connected in lift cylinder 13 tops, this location-plate is the double polarizing keys location-plate, it is made up of with following location-plate 12 the last location-plate 9 that is connected as a single entity, the thickness of last location-plate 9 is 9.6mm, the thickness of following location-plate 12 is 14mm, and following location-plate 12 is along the center line left-right symmetry of last location-plate 9.Pressing tongs 5, heating plate 7 are driven by last pressing tongs cylinder 6 and heating plate cylinder 14 respectively on preceding upward pressing tongs 8, the back, and last pressing tongs cylinder 6 and heating plate cylinder 14 are connected on the frame 1.
