[0002] Currently, soft bag cartoning machines on the market suffer from low automation levels in shaping and loading, high labor costs, and slow cartoning efficiency. To address these issues, our company has developed and designed a soft bag shaping and pressing mechanism for cartoning machines. This utilizes continuous belt conveyor loading, replacing the manual loading process of existing equipment. This ensures high-speed, stable, and reliable machine operation, making soft bag cartoning more efficient. The optimized mechanical structure reduces labor costs and significantly increases production speed. This machine also features easy operation, attractive design, and convenient maintenance.

[0003] Publication number CN210956884U discloses a battery cell feeding and conveying device comprising a turntable with multiple workstations, a battery cell fixture mounted on the workstations, and a conveying power member for driving the turntable to rotate. The battery cell fixture comprises a fixture base, a material unloading platform mounted on the fixture base, a pressing rod rotatably connected to the fixture base at one end, and a pressing power member for driving the pressing rod to compress or release the battery cell. In this disclosure, the workstations on the turntable rotate as the turntable rotates, and the workstations are oriented radially with respect to the turntable and are in a stationary position relative to the turntable. Because the workstations rotate with the turntable, coordination between the workstations and other mechanisms is difficult. Utility Model Content

[0024] like Figure 1 and Figure 2 The illustrated embodiment shows a soft bag shaping and pressing mechanism, comprising a main transmission shaft 1, a rotating disk 2 being fixed at one end thereof, and three pressing mechanism groups 3 being provided on the rotating disk 2. In this embodiment, there are two pressing mechanism units 31, each of which has a fixed shaft 312 fixed to the rotating disk 2 via a bearing 311, and a synchronous pulley 313 being provided on the fixed shaft 312. The transmission assembly 4 includes a synchronous belt 41, which connects the synchronous pulley 313 in each pressing mechanism unit 31 to the main transmission shaft 1. In this embodiment, the transmission assembly 4 also includes a tensioning structure 42, which includes a base 421 fixed to the rotating disk 2, a tensioning shaft 422 being provided on the base 421, and a tensioning pulley 423 being provided on the tensioning shaft 422, which acts on the synchronous belt 41.

[0025] In this embodiment, a synchronous transmission mechanism 5 is provided on the main transmission shaft 1, and the synchronous transmission mechanism 5 includes a primary sprocket 51, which is provided at the other end of the main transmission shaft 1; a secondary sprocket 52, which is provided on the bracket of the soft bag shaping and pressing mechanism, and the secondary sprocket 52 is connected to the primary sprocket 51 through a chain; a power shaft 53, which is provided on the bracket and is integrated with the conveying mechanism of the soft bag shaping and pressing mechanism, and the power shaft 53 is connected to the secondary sprocket 52 through a secondary chain.

[0026] In this embodiment, the pressing mechanism unit 31 includes a pressing support block 321, the pressing support block 321 has a pressing plate member 323 that reciprocates in the vertical direction, and the pressing plate member 323 includes a limiting member 324 located in the pressing support block 321; it also includes a connecting rod 325 located in the limiting member 324, a limiting block 326 located at the upper end of the connecting rod 325, a pressing block 327 located at the lower end of the connecting rod 325, and an elastic mechanism 328 located between the pressing block 327 and the limiting member 324 and sleeved on the connecting rod 325.

[0027] The pressing mechanism unit 31 includes an adjusting block 32, which is connected to a fixed base mechanism 320. The fixed base mechanism 320 includes a connecting block 91, which is clamped in the adjusting block 32 and has multiple adjusting holes perpendicular to the adjusting block 2, wherein the upper end has an axis fixing hole; a fixed shaft 312, one end of the fixed shaft 312 is clamped in the axis fixing hole; and a bearing member 311, which is arranged at the other end of the fixed shaft 92 and fixed in the rotating disk 2.

[0028] The pressing mechanism group 3 of this embodiment is connected to the main transmission shaft 1 through the transmission assembly 4, so that when the main transmission shaft 1 rotates, the pressing plate of the pressing mechanism unit 31 in the pressing mechanism group 3 is always in a vertical downward position driven by the transmission assembly 4.

[0029] When products follow the conveyor belt and fall into the cartoner's chute, the flexible pouches experience varying heights due to varying forces, hindering subsequent pushing and cartoning. A pressing and buffering mechanism precisely compacts the products at the corresponding chute locations. The cartoner's main drive shaft 1 provides power, and the primary sprocket 51 drives the rotating disc 2.

[0030] The cartoning machine's main drive shaft 1 rotates once, resulting in the trough moving 1.5 stations. The trough spacing is 101.6 mm, and the central pitch of the rotary disc 2 is 6 troughs. Driven by the synchronous transmission mechanism 5, the rotary disc 2 is decelerated by the primary sprocket 51 and the secondary sprocket 52, so that the rotary disc 2 rotates 1 / 4 of a turn for every rotation of the main drive shaft 1. This ensures that the pressing mechanism always maintains the same speed as the trough movement.
