Automatic machine for cutting, fusing, and reeling raw material plates of plastic material

A machine for cutting, fusing, and reeling raw material plates of plastic material, the machine comprising:

• a feeding assembly for feeding a raw material plate having irregular front and rear ends and two irregular sides;
• a front electric heating assembly for cutting the irregular front end of the raw material plate;
• a first transportation means for transporting the raw material plate fed by the feeding assembly to the front electric heating assembly;
• a front clamping assembly for clamping the front end of the raw material plate to be cut;
• a rear electric heating assembly for fusing the cut front end of the raw material plate and a rear end of a previously cut material plate together to form a material web and for cutting the irregular rear end of the raw material plate;
• a second transportation means for transporting the raw material plate from the front electric heating assembly to the rear electric heating assembly;
• a movable table means provided between the front and rear electric assemblies and movable along a feeding direction of the raw material plate for transporting the raw material plate and for clamping the raw material plate during the transportation;
• a rear clamping assembly for clamping the rear end of the raw material plate to be cut;
• a side cutting assembly for cutting the sides of the fused material web;
• a reel assembly for coiling the material web;
• and
• a third transportation assembly for transporting the material web to the reel assembly;
• wherein each of the front and rear electric heating assemblies comprises:
• a cylinder means having a sliding block;
• a heating blade unit having an upper portion, a lower portion, and a heating blade securely mounted between the upper and lower portions;
• a transmitting means comprising a driving toothed belt adjustably coupled to the upper portion of the heating blade unit and securely attached to the sliding block of the cylinder means and horizontally driven thereby, a driven toothed belt adjustably coupled to the lower portion of the heating blade unit, and a pair of opposite vertical transmitting shafts connecting the driving and driven toothed belts, thereby allowing synchronous horizontal movement of the upper and lower portions of the heating blade unit under operation of the cylinder means, wherein the pair of the opposite transmitting shafts are rotatably mounted to opposite sides of the machine respectively and each of the pair of the opposite transmitting shafts has a splined periphery upper end and a splined periphery lower end, and wherein each of the driving and driven toothed belt has a toothed face, the driving toothed belt being mated around the splined periphery of the upper ends of the transmitting shafts with the toothed face thereof engaging with the splined periphery upper ends of the shafts, and the driven belt being mated around the splined periphery lower ends of the transmitting shafts with the toothed face thereof engaging with the splined periphery lower ends of the shafts;
• and
• a control means for controlling a stroke of the horizontal movement of the heating blade unit according to a predetermined width of the web.
