Description

Technical Field

[0001] This utility model relates to a production line for packaging bags such as cement bags and chemical bags, and in particular to an auxiliary feeding mechanism. Background Technology

[0002] The production of packaging bags such as cement bags and chemical bags usually uses paper rolls as the core raw material and is completed through multiple processes such as gluing, cutting, and bag making. Among these processes, the placement and replacement of the raw paper rolls are important factors affecting production efficiency and operational safety.

[0003] Currently, raw paper rolls are placed directly on the discharge mechanism. When a roll is used up, the machine needs to be stopped to replace it. This process interrupts the production flow, and each stop to replace the roll wastes a lot of production time. Especially in large-scale continuous production scenarios, frequent shutdowns greatly reduce overall production efficiency and increase production cycle and cost. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides an auxiliary feeding mechanism.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] An auxiliary feeding mechanism includes a frame for placing raw material paper rolls, a first slot for placing the center roller of the raw material paper rolls on the frame, a hinge roller mounted on the frame, hinge components driven to rotate by cylinders rotatably mounted at both ends of the hinge rollers, an auxiliary bracket rotatably mounted on the side of the hinge components away from the cylinders, and a second slot for placing the center roller of the raw material paper rolls on the auxiliary bracket.

[0007] The frame includes a base, and mounting brackets are installed on both sides of the base. The first bayonet is located on the upper side of the mounting bracket, and the two sides of the hinge roller are respectively mounted on the mounting brackets on both sides.

[0008] The hinge assembly includes rotating blocks on both sides and connecting rods fixedly connected to the rotating blocks. The two rotating blocks are respectively installed on both sides of the hinge roller. A limit notch is provided on the mounting frame, and the end of the connecting rod is inserted into the limit notch.

[0009] The end of the auxiliary support extends below the hinge roller.

[0010] The beneficial effects of this utility model are as follows: This utility model has a first slot on the frame for placing the center roller of the raw material paper roll. A hinge roller is installed on the frame. Both ends of the hinge roller are rotatably mounted with hinge components driven by cylinders. An auxiliary support is rotatably mounted on the side of the hinge component away from the cylinder. The auxiliary support is provided with a second slot for placing the center roller of the raw material paper roll. The raw material paper roll that has been produced to a certain extent is removed from the first slot through the auxiliary support. At this time, the auxiliary support serves as the output end of the production raw material. The first slot on the frame is used to put in a new raw material paper roll. After the raw material paper roll in the auxiliary support is completely consumed, a new raw material paper roll can be connected to the production line, thereby greatly improving the efficiency of paper roll replacement.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0017] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0018] The following describes some embodiments of the present invention with reference to the accompanying drawings.

[0019] Reference Figure 1-4 An auxiliary feeding mechanism includes a frame 1 for placing raw material paper rolls, a first slot 2 for placing the center roller of the raw material paper roll on the frame 1, a hinge roller 3 mounted on the frame 1, hinge components 5 driven to rotate by cylinders 4 rotatably mounted at both ends of the hinge roller 3, an auxiliary bracket 6 rotatably mounted on the side of the hinge component 5 away from the cylinders 4, and a second slot 7 for placing the center roller of the raw material paper roll on the auxiliary bracket 6.

[0020] During initial production, a new raw material paper roll is placed on the first slot 2 for production. When the raw material paper roll is reduced to a certain extent, the worker manually swings the auxiliary support 6 so that the second slot 7 engages with the center roller of the raw material paper roll. At this time, the cylinder 4 is activated, causing the hinge assembly 5 to rotate around the hinge roller 3. Through the lever structure, the auxiliary support 6 is moved upward, thereby lifting the raw material paper roll for normal production. The worker then swings the auxiliary support 6 again, causing the center roller of the raw material paper roll to move away from above the first slot 2. The cylinder 4 is activated again, causing the hinge assembly 5 to rotate in the opposite direction around the hinge roller 3, thereby removing the raw material paper roll. The auxiliary support 6 serves as the output end of the production raw material. At this time, a new raw material paper roll can be installed on the first slot 2 using a crane or other device. After the raw material paper roll on the auxiliary support 6 is completely consumed, a new raw material paper roll can be connected to the production line, thereby greatly improving the efficiency of paper roll replacement.

[0021] Furthermore, a first bearing 14 is installed on the frame 1 within the first bayonet 2.

[0022] The second bearing 13 is installed inside the second bayonet 7, which effectively improves the smoothness of feeding the raw material paper roll.

[0023] The frame 1 includes a base 8, and mounting brackets 9 are installed on both sides of the base 8. The first bayonet 2 is located on the upper side of the mounting bracket 9. The two sides of the hinge roller 3 are respectively installed on the mounting brackets 9 on both sides. The hinge assembly 5 includes rotating blocks 10 on both sides and connecting rods 11 fixedly connected to the rotating blocks 10. The two rotating blocks 10 are fixedly connected by the connecting rods 11, thereby achieving the effect of synchronous rotation of the two rotating blocks 10. The two rotating blocks 10 are respectively installed on both sides of the hinge roller 3.

[0024] Furthermore, the mounting bracket 9 is provided with a limiting notch 12, and the end of the connecting rod 11 is inserted into the limiting notch 12. When the connecting rod 11 is located at the lowermost side of the limiting notch 12, it is the initial position of the auxiliary bracket 6 (e.g., Figure 1 As shown in Figure A); the connecting rod 11 is located at the middle section of the limiting notch 12, at which time the second latch 7 engages with the center roller of the raw material paper roll (as shown in Figure A). Figure 2 (As shown in B); the connecting rod 11 is located at the uppermost side of the limiting notch 12. At this time, the auxiliary bracket 6 lifts the raw material paper roll away from the first bayonet 2 (as shown in B). Figure 3 (as shown in C).

[0025] Furthermore, the cylinder 4 is rotatably mounted on the frame 1 via the mounting bracket 15. When the worker swings the auxiliary support 6, the mounting bracket 15, cylinder 4, rotating block 10 and other components will rotate accordingly. At this time, the cylinder 4 will not start. When the second latch 7 is engaged with the center roller of the raw material paper roll, the cylinder 4 starts, and the auxiliary support 6 can be pushed up through the lever principle, thereby lifting the raw material paper roll.

[0026] The end of the auxiliary support 6 extends below the hinge roller 3. When the auxiliary support 6 is in the initial position, the end of the auxiliary support 6 abuts against the hinge roller 3. At this time, the connecting rod 11 is located at the lowest side of the limiting notch 12. The connecting rod 11 can be regarded as a fixing rod. The auxiliary support 6 can rotate downward around the connecting rod 11. When the end of the auxiliary support 6 abuts against the hinge roller 3, the auxiliary support 6 cannot continue to move downward, thereby achieving the fixation of the auxiliary support 6. When the auxiliary support 6 is used as the output end of the production raw material, it can also have sufficient stability.
