[0022] The packaging film 4 is specifically a bubble film, which has many advantages such as buffering and vibration prevention, anti-static, moisture-proof and dust-proof, transparent and visible, and cost-effective; The hot pressing plate 20 is arranged in a circular shape, and an electric heating wire is arranged inside the hot pressing plate 20 for heating and bonding the two layers of packaging film 4; When packaging thick film resistors, firstly, packaging films 4 are installed on the outer walls of the first installation roller 2 and the second installation roller 3, and then the ends of the two packaging films 4 away from the first installation roller 2 and the second installation roller 3 are placed under the cutting plate 6 and then installed on the outer wall of the winding roller 5. After the packaging films 4 are installed, the motor 15 is started. When the motor 15 is started, the second rotating shaft 14 is driven to rotate.

When the third rotating shaft (17) rotates, the winding roller (5) is driven to rotate through the first pulley group (18), so that the winding roller (5) winds up the packaging film (4) on the outer wall of the first installation roller (2) and the second installation roller (3), pulling the thick film resistor located on the surface of one of the packaging films (4) to move to the bottom of the cutting plate (6); S3: The rotation of the second gear (13) drives the rotation of the first gear (12), the rotation of the first gear (12) drives the rotation of the first rotating shaft (11), the rotation of the first rotating shaft (11) drives the rotation of the second bevel gear (10), the rotation of the second bevel gear (10) drives the rotation of the first bevel gear (9), the rotation of the first bevel gear (9) drives the rotation of the reciprocating screw (8), the rotation of the reciprocating screw (8) drives the connecting plate (7) to move back and forth, the movement of the connecting plate (7) drives the movement of the cutting plate (6), the movement of the cutting plate (6) drives the cutting knife (19) and the hot pressing plate (20) to move downward, the hot pressing plate (20) presses down to press and heat-seal the two layers of packaging film (4), and at the same time the cutting knife (19) presses down to cut the two layers of packaging film (4), thereby completing the packaging of the thick film resistor; S4: Then the second gear (13) continues to rotate so that the winding roller (5) winds up the packaging film (4) on the outer wall of the first installation roller (2) and the second installation roller (3), and winds up the cut scraps, while the packaged thick film resistor is located above the transmission roller (26). At the same time, the rotation of the second rotating shaft (14) drives one of the fourth rotating shafts (27) to rotate through the second pulley group (29), and the rotation of the fourth rotating shaft (27) drives the rotation of the fourth gear (28). The rotation of the fourth gear (28) drives the other transmission rollers (26) to rotate synchronously through the chain (32), so that the transmission roller (26) rotates to transmit the packaged thick film resistor and transport it to the collection box (31) for collection; S5: Repeat the above steps to perform continuous packaging operations.
