Cross sealing device

A cross sealing device (100) comprising:

• a cross sealing table (X), wherein the cross sealing table (X) is comprising:
• a cross sealing station (A) comprising:
• a front seal assembly (1) comprising a first seal jaw (1a) with a perforation blade (1b);
• and
• a rear seal assembly (2) comprising a second seal jaw (2a) with a perforation slot (2b) configured to receive the perforation blade (1b) upon engagement with the first seal jaw (1a);
• a pair of parallel linear motion rods (4a, 4b), wherein the front seal assembly (1) is fixedly mounted at a front end of the pair of parallel linear motion rods (4a, 4b), and a back connecting plate (10) is fixedly mounted at a rear end thereof;
• and
• a toggle assembly (B) comprising:
• a sealing drive shaft (5) provided perpendicularly between the pair of parallel linear motion rods (4a, 4b);
• a pair of cross connecting lever (7a, 7b) fixedly mounted with a sealing drive shaft (5);
• a first pair of C shaped actuator levers (6c, 6d) fixedly connected with the rear seal assembly (2) at a front end thereof;
• a second pair of C shaped actuator levers (6a, 6b) fixedly connected with the back connecting plate (10) at a rear end thereof, wherein the rear end of the first pair of C shaped actuator levers (6c, 6d) and a back end of the second pair of C shaped actuator levers (6a, 6b) are rotatably connected with each of the pair of cross connecting lever (7a, 7b) at opposite ends thereof;
• a first timing pulley (11) mounted on the sealing drive shaft (5) to control oscillation of the sealing drive shaft (5);
• and
• a first servo motor (M1) configured to control oscillation of the first timing pulley (11);
• and
• a cross seal vertical up down control assembly (C) comprising a cross seal up down plate (13) which slides on a pair of linear motion rails (16) mounted on a rail mounting plate (15) at one end via a pair of parallel linear motion guide blocks (14) wherein the cross seal up down plate (13), at another end, is fixed with a timing belt (17) which is oscillating vertically on a first driver timing pulley (19) and a second driven timing pulley (20) attached with the rail mounting plate (15).
