DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] See also Figures 1 to 6As an embodiment of the present utility model, an automatic heat-sealing device for finished packaging bags includes a frame 1, a bracket 2 is fixed on the frame 1, two adjustment frames 4 are slidably provided on the bracket 2, and a heat-sealing plate 5 for heat-sealing the packaging bags is installed on the adjustment frame 4. Two turntables 6 are rotatably provided on the bracket 2, and the turntables 6 are connected to the adjustment frames 4 via a first linkage structure. When the turntable 6 rotates clockwise or counterclockwise, it drives the two adjustment frames 4 to move relative to or toward each other;

[0027] A cylinder 9 is fixed on the bracket 2, and a piston rod 10 is installed at the output end of the cylinder 9. The piston rod 10 is connected to one of the turntables 6 through a second linkage structure. When the piston rod 10 moves in a telescopic manner, it drives the turntable 6 to rotate clockwise or counterclockwise.

[0028] A fixing frame 11 is fixed on the piston rod 10. One side of the fixing frame 11 is connected to a supporting plate 12 for placing the finished packaging bags through an elastic component. A baffle 15 is fixed on the bracket 2 to block the supporting plate 12 from moving.

[0029] In this embodiment, after the finished packaging bag is placed on the supporting plate 12, the cylinder 9 is started to drive the piston rod 10 to extend and retract, so that the finished packaging bag can be automatically transported to one side of the heat-sealing plate 5, and when the piston rod 10 moves outward, it will drive the turntable 6 to rotate counterclockwise, thereby driving the two adjusting frames 4 to move toward each other, driving the two heat-sealing plates 5 to move and heat-seal the finished packaging bag. After the sealing is completed, the piston rod 10 retracts, and the turntable 6 rotates clockwise, thereby driving the two adjusting frames 4 to move relative to each other, driving the two heat-sealing plates 5 to move and release the hot pressure fixation of the finished packaging bag. During the contraction process of the piston rod 10, the supporting plate 12 is automatically driven to move and reset, thereby automatically transporting the heat-sealed finished packaging bag outward for easy removal.

[0030] As a further solution of the present invention, an electrical controller 18 for controlling electrical components of the device is fixedly mounted on the frame 1 .

[0031] In this embodiment, it is convenient to control the electrical components of the device and improve the degree of automation.

[0032] As a further solution of the present invention, two limiting rods 3 are fixed on the bracket 2, and a through hole with an inner diameter matching the outer diameter of the limiting rod 3 is opened on the adjustment frame 4, and the limiting rod 3 is set through the through hole.

[0033] In this embodiment, the limiting rod 3 passes through the through hole provided on the adjusting frame 4 , so that the adjusting frame 4 can slide smoothly on the limiting rod 3 .

[0034] As a further solution of the present invention, the first linkage structure includes hinged rods 7 respectively provided between the turntable 6 and the two adjustment frames 4 , and both ends of the hinged rod 7 are hinged to the turntable 6 and the adjustment frames 4 respectively.

[0035] In this embodiment, the rotation of the turntable 6 drives the hinge rod 7 to swing, thereby pulling the adjustment frame 4 to move. When the turntable 6 rotates clockwise, the two adjustment frames 4 move relative to each other. When the turntable 6 rotates counterclockwise, the two adjustment frames 4 move toward each other.

[0036] As a further solution of the present invention, the elastic component includes a telescopic rod 13 fixed between the fixing frame 11 and the supporting plate 12 , and a spring 14 is sleeved on the telescopic rod 13 .

[0037] In this embodiment, the telescopic rod 13 includes an outer tube 1301 and an inner rod 1302. The inner rod 1302 is movably inserted into the outer tube 1301. A protrusion is fixed on one end of the inner rod 1302 located in the outer tube 1301, and a retaining ring is fixed on one end of the outer tube 1301. The protrusion cooperates with the retaining ring to prevent the inner rod 1302 from slipping out of the outer tube 1301. The telescopic rod 13 is telescopic and the piston rod 10 will drive the supporting plate 12 to move when it is telescopic. When the supporting plate 12 moves to the side of the baffle 15, it is blocked by the baffle 15, and the supporting plate 12 stops moving forward. The finished packaging bag on the supporting plate 12 remains stationary. Since the telescopic rod 13 is telescopic, the piston rod 10 can continue to move forward for a distance, ensuring that the two heat sealing plates 5 move toward each other to heat seal the stationary finished packaging bag.

[0038] As a further solution of the present invention, the second linkage structure includes a rotating drum 8 fixed on the turntable 6, the rotating drum 8 is rotatably mounted on the bracket 2 through a bearing, the piston rod 10 is movably inserted into the inside of the rotating drum 8, and a ball 16 is embedded in the inner wall of the rotating drum 8. A track groove 17 is opened on the surface of the piston rod 10, and the ball 16 is movably clamped in the inside of the track groove 17 and can roll along the track where the track groove 17 is located.

[0039] In this embodiment, when the piston rod 10 moves forward, it will be movably inserted into the drum 8, so that the ball 16 rolls on the track where the track groove 17 is located to drive the drum 8 to rotate counterclockwise. When the piston rod 10 is retracted backward, it drives the drum 8 to rotate clockwise.

[0040] As a further solution of the present invention, a soft rubber layer is fixedly adhered to the surface of the baffle 15 .

[0041] In this embodiment, the soft rubber layer is soft and elastic, and can cushion the impact of the supporting plate 12 on it, thereby reducing on-site working noise.

[0042] As a further solution of the present invention, a plurality of strip-shaped protrusions distributed at equal intervals are fixed on the surface of the heat sealing plate 5 , and an electromagnetic coil is built into the heat sealing plate 5 , which is electrically connected to the electrical controller 18 through a wire.

[0043] In this embodiment, the electromagnetic coil is energized to heat the heat-sealing plate 5 , and the two heat-sealing plates 5 are pressed relative to each other, and the heated strip-shaped protrusions are used to heat-seal the finished packaging bag.

[0044] The working principle of the utility model is as follows: after the finished packaging bag is placed on the supporting plate 12, the cylinder 9 is started to drive the piston rod 10 to extend and retract, so that the finished packaging bag can be automatically transported to the side of the heat-sealing plate 5, and when the piston rod 10 moves outward, it will drive the turntable 6 to rotate counterclockwise, thereby driving the two adjustment frames 4 to move toward each other, driving the two heat-sealing plates 5 to move and heat-seal the finished packaging bag. The telescopic rod 13 can be extended and retracted, and when the piston rod 10 extends and retracts, it will drive the supporting plate 12 to move. When the supporting plate 12 moves to the side of the baffle 15, it is blocked by the baffle 15, and the supporting plate 12 stops moving forward. The finished packaging bags on the supporting plate 12 remain stationary. Since the telescopic rod 13 is retractable, the piston rod 10 can continue to move forward for a distance, ensuring that the two heat-sealing plates 5 move toward each other to heat-seal the stationary finished packaging bags. After the sealing is completed, the piston rod 10 retracts, and the turntable 6 rotates clockwise, thereby driving the two adjusting frames 4 to move relative to each other, driving the two heat-sealing plates 5 to move and release the hot pressure fixation of the finished packaging bags. During the contraction of the piston rod 10, the supporting plate 12 is automatically driven to move and reset, thereby automatically conveying the heat-sealed finished packaging bags outward for easy removal.

[0045] The above embodiments are exemplary rather than restrictive, so any technical solution of the present invention that can be implemented in other specific forms without departing from the spirit or basic features of the present invention is included in the present invention.
