Equipment principle
The plastic component to be fused is heated with a metal plate with a higher melting point than the plastic material at the junction of the plastic part to be fused to melt the plastic part junction. When the joint surface of the plastic parts is melted, remove the hot metal plate and press the upper and lower two plastic parts to fuse the joint surface.

Hot plate machine welding process
Put in the product under the glue → Lower fixture suction → Put in the product glue part → Upper fixture suction → Press the start button → Hot plate into → Lower pressure plate, lower pressure plate (while moving relative to each other) → Hot blanching → Upper pressure plate, lower pressure plate under → Hot plate de→ Upper pressure plate, lower pressure plate → bonding → upper clamp loose → upper pressure plate, lower pressure plate lower → lower clamp loose → Remove the product
Hot plate moving mechanism
The hot plate moving mechanism is composed of cylinders, slider guides, hot plates and other components. The cylinder is used as the power source to drive the hot plate mechanism to move in a straight line along the two slide guide rails.
Hot plate parts: composed of hot mold and hot plate. The hot mold and the hot plate are connected to the hot plate moving mechanism by quickly positioning the fastening mechanism. The upper and lower hot mold materials are aluminum-copper alloys.
Structural features
The characteristics of the structure are: when the hot plate is in motion, it is stable and the movement gap is small. On the hot plate mechanism, the quick coupling mechanism with hot plate and upper and lower hot mold, as well as the hot mold fixed by the hot plate, can effectively and quickly replace different products, optimize its scope of use, and improve production efficiency.
Upper and lower template running mechanism:
The upper and lower platens are connected to the hot plate by 4 limit guide rods, which can precisely adjust the welding depth and together form the main moving parts of a machine.
Upper template motion mechanism:
The upper pressure plate moving mechanism is composed of cylinder, linear bearing, 4-column φ30 guide rod, mold, mold pneumatic clamping device, vacuum suction cup and other components. The cylinder is used as the power source to drive the pressure plate mechanism to move up and down along the four guide rods. The vacuum system adopts an imported vacuum generator to output vacuum pressure, and firmly sucks the rubber through the vacuum suction cup to ensure the correct positioning of the rubber and does not damage the surface of the glue.
Sports bodies
Template kinematics (ibid.):
The characteristics of the structure are: it can ensure the relative position between the upper and lower products and the upper and lower hot molds and the product joint position, and in the production process, the upper rubber parts can quickly contact the hot mold, and at the same time more quickly and accurately weld together with the lower rubber parts. Equipped with buffer, accurate positioning, vibration reduction, to ensure the size and appearance of the product.
cover
The whole machine is fully enclosed structure, the top of the cover is equipped with a strong exhaust structure, the toxic gas generated during welding is quickly discharged from the internal cavity of the machine, reducing the damage of toxic gas to the operator, and the rear and lower parts of the body are movable doors, which is convenient for maintenance. In order to ensure safe production and reflect the humanized design, a safety light grating is installed at the operation port, and when any part of the human body is in the danger area of the equipment in the automatic welding state, the equipment will stop immediately, and can continue to work only after the danger is lifted.
Hot plate machine control system
The use of programmable controller (PLC), touch screen to control the whole operation process, can be fully automatic operation, can also be manually operated.
Double emergency stop buttons and switch buttons and alarm devices are installed at all ends of the equipment.
The parameter setting interface is locked with a password to prevent unauthorized personnel from modifying and setting parameters.
The status indicator is set on the control panel panel, and various status of the machine can be displayed on the control panel panel.
Equipped with independent distribution box, the circuit is divided into functional blocks, strong current and weak current partition control, in the equipment maintenance, at a glance, easy to maintain.
