Description

Technical Field

[0001] This utility model relates to the field of food packaging technology, and in particular to an automatic bag-feeding mechanism for feeding inner bags into outer bags of food packaging. Background Technology

[0002] Most packaging equipment on the market that uses inner bag to outer bag packaging relies on manual or semi-automatic bagging. Manual bagging is inefficient and cannot guarantee the condition of the inner bag after it is placed in the bag, and problems are prone to occur during subsequent automated operation.

[0003] In view of this, the present invention provides an automatic bag-feeding mechanism that can automatically integrate inner bags and feed outer bags. Due to the use of a turntable mechanism for circulation, it can increase the number of workstations to meet different needs, while also facilitating manual handling. Furthermore, the present invention provides a smooth bagging effect, high efficiency, and compatibility with packaging bags of different sizes. Summary of the Invention

[0004] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide an automatic bag-feeding mechanism for feeding inner bags into outer bags of food packaging.

[0005] The purpose of this utility model is achieved through the following technical solution: an automatic bag-feeding mechanism for feeding inner bags into outer bags of food packaging, including an indexing turntable and a bag-pressing mechanism. The indexing turntable is provided with an inner bag shaping mechanism, a bag-feeding hopper, and an outer bag opening mechanism. The outer bag opening mechanism is located below the bag-feeding hopper. When the indexing turntable drives the inner bag shaping mechanism to rotate to directly below the bag-pressing mechanism, the inner bag shaping mechanism shapes the inner bag and moves the shaped inner bag to the position of the bag-feeding hopper. The outer bag opening mechanism opens the outer bag opening, and the inner bag shaping mechanism releases the inner bag, causing the inner bag to fall from the bag-feeding hopper into the outer bag. The bag-pressing mechanism controls the bag-pressing rod to pass through the bag-feeding hopper and press the inner bag into the bottom of the outer bag.

[0006] As an improvement of the present invention for an automatic bag-feeding mechanism for food packaging inner bag to outer bag, the bag-pressing mechanism includes a bag-pressing lifting control servo module, which controls a lifting plate to move up and down. A bag-pressing rod mounting plate is installed on the lifting plate, and a bag-pressing rod mounting seat is provided on the bag-pressing rod mounting seat. A bag-pressing rod is provided on the bag-pressing rod mounting seat.

[0007] As an improvement of the automatic bag-feeding mechanism for food packaging inner bag to outer bag, the bottom of the bag-pressing rod is provided with a pressing rod head, and two corresponding bag-pressing plates are spaced apart on the pressing rod head. The pressing rod head is provided with a convex groove, and the bottom of the bag-pressing rod is provided with a convex connecting block, which cooperates with the convex groove.

[0008] As an improvement of the present invention for an automatic bag-feeding mechanism for inner bag to outer bag in food packaging, the bag-pressing lifting control servo module includes a column, a module profile on one side of the column, two synchronous pulleys and a synchronous belt on the module profile, the two synchronous pulleys being connected by the synchronous belt, a lifting plate being connected to the synchronous belt, a driven synchronous pulley being provided on the axle of one of the synchronous pulleys, the driven synchronous pulley being connected to the driving synchronous pulley through a second synchronous belt, the driving synchronous pulley being mounted on the output shaft of the lifting control servo motor, and the lifting control servo motor being mounted on the upper end of the module profile.

[0009] As an improvement of the automatic bag-feeding mechanism for food packaging inner bags into outer bags, the inner bag shaping mechanism includes a vertical plate with a bidirectional control cylinder. Piston rods are located at both ends of the bidirectional control cylinder, and each piston rod is connected to a shaping pressure plate. The corresponding surfaces of the two shaping pressure plates are provided with shaping grooves. An inlet window is located at the top of the vertical plate. The inner bag falls through the inlet window between the two shaping pressure plates. The bidirectional control cylinder simultaneously controls the two shaping pressure plates to move closer together and squeeze the inner bag. A lateral control cylinder controls the vertical plate to move, moving the inner bag to the position of the inlet hopper. A side shaping cylinder controls the side shaping plate to move and squeeze the side of the inner bag. When the outer bag opening is opened, the bidirectional control cylinder and the side shaping cylinder reset and release the inner bag, causing it to fall from the inlet hopper into the outer bag. The pressing mechanism then controls the pressing rod to press down, pressing the inner bag into the bottom of the outer bag.

[0010] As an improvement of the present invention for an automatic bag-feeding mechanism for food packaging inner bags into outer bags, the inner bag shaping mechanism further includes a side shaping mechanism, the side shaping mechanism includes a side shaping cylinder mounting plate, the side shaping cylinder mounting plate is provided with a side shaping cylinder, and the piston rod end of the side shaping cylinder is provided with a side shaping block.

The bottom of the upright plate is provided with a connecting plate, which is slidably connected to the slide rail by a slider. The piston rod of the transverse control cylinder is connected to the connecting plate, and the transverse control cylinder can control the horizontal movement of the upright plate.

[0012] As an improvement of the present invention for an automatic bag-feeding mechanism for food packaging inner bag to outer bag, the outer bag opening mechanism includes an opening cylinder and an opening guide plate. The piston rod end of the opening cylinder is provided with an opening connecting plate. Both ends of the opening connecting plate are respectively provided with opening control rods.

Each of the two bag opening plate mounting plates is provided with a rotatable bag opening plate. Both ends of the bag opening plate are provided with a fixing rod, and the fixing rod is connected to the connecting shaft through a connecting arm.

[0014] When the bag-opening cylinder controls the bag-opening control lever to move upward, the two bag-opening plates rotate and move closer to each other.

[0015] When the bag-opening cylinder controls the bag-opening control lever to move downward, the two bag-opening plates rotate and move away from each other to open.

[0016] The beneficial effects of this utility model are as follows: This utility model can achieve fully automatic integration of inner bags and outer bags. Due to the use of a turntable mechanism for circulation, it can increase the number of workstations to meet different needs, while also facilitating manual handling. Furthermore, this utility model provides a smooth bagging effect, high efficiency, and compatibility with packaging bags of different sizes.
