[0053] See Figures 1 to 5As shown in the figure, an embodiment of the present application provides a bag loading device for a packaging bag, which is installed on the frame of a food packaging device and is used to clamp the packaging bags conveyed by a packaging bag conveyor to a specified station, so as to facilitate subsequent packaging operations such as filling and sealing. The bag loading device for a packaging bag mainly includes a cam 11 transmission mechanism 10, a synchronous belt 21 transmission mechanism 20, and a clamping mechanism 30, where:

[0054] The cam 11 transmission mechanism 10 includes a cam 11, a transmission plate 12, a connecting seat 13, a transmission rod 14, a connecting sleeve 15, and a first rotating shaft 16. The cam 11 is connected to a power source on the food packaging device. The transmission plate 12 is leaned against the cam 11. One end of the transmission plate 12 is hinged to the connecting seat 13, and the connecting seat 13 is installed on the frame of the food packaging device. The other end of the transmission plate 12 is hinged to the lower end of the transmission rod 14. The upper end of the transmission rod 14 is hinged to the connecting sleeve 15. The first rotating shaft 16 is passed through the connecting sleeve 15, and the first rotating shaft 16 is connected to the first rotating shaft 16 bracket through a bearing. The first rotating shaft 16 bracket is installed on the frame of the food packaging device.

[0055] The synchronous belt 21 transmission mechanism 20 includes a synchronous belt 21, a first pulley 22, a second pulley 23, and a second rotating shaft 24. The first pulley 22 is sleeved on the first rotating shaft 16, the second pulley 23 is sleeved on the second rotating shaft 24, and the first pulley 22 and the second pulley 23 are connected by the synchronous belt 21. The second rotating shaft 24 is connected to the second rotating shaft 24 bracket through a bearing, and the second rotating shaft 24 bracket is installed on the frame of the food packaging device.

[0056] The clamping mechanism 30 includes a connecting arm 31, a connecting plate 32, a clamping cylinder 33, and a clamping assembly 34. The connecting arm 31 is connected to the second rotating shaft 24, the connecting plate 32 is installed on the connecting arm 31, and the clamping cylinder 33 is connected to the connecting arm 31. The clamping assembly 34 includes two symmetrically arranged clamping plates 341. The top of the clamping plate 341 has a short shaft 342, and a gear 343 is arranged on the short shaft 342. The short shaft 342 is hinged to the connecting plate 32, and the gears 343 of the two clamping plates 341 are meshed with each other. The clamping cylinder 33 is hinged to the top of the outer clamping plate 341.

[0057] The power source on the food packaging equipment drives the cam 11 to rotate. The rotation of the cam 11 drives the transmission plate 12 to rotate reciprocally. The transmission plate 12 drives the transmission rod 14 to rotate reciprocally up and down. The transmission rod 14 then drives the connecting sleeve 15 to rotate reciprocally, thereby causing the first rotating shaft 16 to rotate reciprocally. When the first rotating shaft 16 rotates reciprocally, it drives the first pulley 22 to rotate reciprocally, thereby driving the second rotating shaft 24 to rotate reciprocally through the synchronous belt 21 and the second pulley 23. Furthermore, it drives the connecting arm 31 to rotate, enabling the connecting arm 31 to rotate from the horizontal direction to the vertical direction, causing the clamping assembly 34 to extend outward to the position of the packaging bag conveyed by the packaging bag conveyor. The two clamping plates 341 are respectively located on both sides of the packaging bag. Then, the clamping cylinder 33 is started, causing the two clamping plates 341 to approach each other and clamp the packaging bag. Then, the connecting arm 31 is rotated from the vertical direction to the horizontal direction, thereby clamping the packaging bag to the designated station of the food packaging equipment.

[0058] The packaging bag loading device of the embodiment of the present application adopts a mechanical structure with the rotation of the cam 11. The cam 11 can share the power source with other mechanisms on the food packaging equipment, eliminating the need to add an additional motor, making the structure simpler. Thanks to the cooperation between the mechanical components, it has higher reliability.

[0059] Specifically, the cam 11 transmission mechanism 10 further includes a reset assembly. The reset assembly includes a reset spring 17 and a spring fixing plate 18. The spring fixing plate is installed on the frame of the food packaging equipment. The spring fixing plate is arranged below the transmission plate 12. The upper end of the reset spring 17 is connected to the transmission plate 12, and the lower end of the reset spring 17 is connected to the spring fixing plate 18. The side end of the transmission plate 12 has a roller 19. The transmission plate 12 is leaned on the cam 11 through the roller 19. A downward pulling force is applied to the transmission plate 12 through the reset spring 17, so that the roller 19 of the transmission plate 12 is leaned on the cam 11.

[0060] Specifically, a first limiting plate 241 and a second limiting plate 242 are provided on the second rotating shaft 24. The first limiting plate 241 and the second limiting plate 242 are located above the second limiting plate 242. The first limiting plate 241 protrudes obliquely upward, and the second limiting plate 242 protrudes directly downward. A first buffer 60 and a second buffer 70 are provided on the second rotating shaft 24 bracket. The first buffer 60 is arranged above the second buffer 70. The head end of the first buffer 60 faces obliquely upward, and the head end of the second buffer 70 is horizontally oriented towards the second limiting plate 242. When the second rotating shaft 24 rotates, it will drive the first limiting plate 241 and the second limiting plate 242 to rotate together. The rotation angles of the first limiting plate 241 and the second limiting plate 242 are restricted by the first buffer 60 and the second buffer 70, thereby preventing the second rotating shaft 24 from rotating excessively due to reasons such as out of control. Moreover, the first buffer 60 and the second buffer 70 can also play a role in reducing impact.
