Technical Field

[0001] The utility model relates to the technical field of bag-making machine feeding, in particular to a bag-making machine feeding device. Background Art

[0002] A bag-making machine is a piece of machinery used to produce various types of packaging bags. It cuts, prints, laminates, and seals various types of film or paper materials to create packaging bags suitable for the food, pharmaceutical, chemical, and other industries. Bag-making machines typically use bundled raw materials. These materials can be rolls of plastic film, paper, or composite materials. Depending on the bag-making machine's design and operating requirements, the raw materials are pre-loaded into the machine in bundles. This practice improves production efficiency, reduces the frequency of raw material changes, and facilitates automated operation. Bundled raw materials can be accurately fed into the bag-making machine using appropriate feeding devices, ensuring a stable and continuous production process.

[0003] However, traditionally, when loading bundled raw materials, workers lift the bundled raw materials to the top of the placement rack, which takes a long time and increases the labor input. To address the above problems, the inventors proposed a feeding device for a bag making machine to solve the above problems. Utility Model Content

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Example: Figure 1-4 As shown, the utility model provides a feeding device for a bag making machine, comprising a bottom plate 1, a first side plate 2 and a second side plate 3 are fixedly connected to both sides of the top of the bottom plate 1, the first side plate 2 and the second side plate 3 are symmetrically distributed, one side of the bottom of the first side plate 2 and the second side plate 3 are fixedly connected to a fixed block 4, a rotating rod 5 is rotatably connected between the two fixed blocks 4, both ends of the rotating rod 5 extend to one side of the fixed block 4 and are fixedly connected to a rotating plate 6, a placement groove 7 is opened on one side of the rotating plate 6, a rotating roller 8 is placed inside the placement groove 7, and a bag making raw material 9 is sleeved on the outer side of the rotating roller 8.

[0019] A servo motor 11 is fixedly installed on the side of the first side plate 2 away from the second side plate 3. The driving end of the servo motor 11 extends to the inner side of the first side plate 2 and is fixedly connected to the first gear 12. The outer side of the rotating roller 8 close to one end of the first gear 12 is fixedly connected to the second gear 13. The first gear 12 and the second gear 13 are meshed and connected.

[0020] By adopting the above technical solution, the servo motor 11 drives the first gear 12 to rotate. When the first gear 12 is in contact and meshing with the second gear 13, the second gear 13 is driven to rotate at the same time, thereby realizing the unwinding operation of the bag-making material 9.

[0021] An electric cylinder 10 is rotatably mounted on one side of the first side plate 2 and the second side plate 3 that is away from each other, and piston rods of the electric cylinder 10 are rotatably connected to the corresponding rotating plates 6 .

[0022] By adopting the above technical solution, the piston rod of the electric cylinder 10 is extended and retracted to push the rotating plate 6 to rotate, thereby driving the bag-making raw material 9 to rotate synchronously with the rotating plate 6, and placing the bag-making raw material 9 into the inside of the placement groove 7, thereby realizing the loading operation.

[0023] A clamping groove 15 is formed on one side of each of the first side plate 2 and the second side plate 3 , and the rotating roller 8 is movably clamped in the clamping groove 15 .

[0024] By adopting the above technical solution and providing the clamping groove 15 , when the rotating roller 8 rotates the rotating plate 6 to the inside of the clamping groove 15 , the clamping groove 15 is used to limit the rotating roller 8 .

[0025] Two transmission rollers 14 are rotatably connected to one side of the first side plate 2 and the second side plate 3 opposite to each other and located at the side of the clamping slot 15 , and the rotating roller 8 is placed between the top ends of the transmission rollers 14 .

[0026] By adopting the above technical solution and providing the transmission roller 14, the rotating roller 8 can be rotated better.

[0027] The placement groove 7 and the rotating plate 6 form an angle of 45 degrees.

[0028] By adopting the above technical solution, by setting the placement groove 7 and the rotating plate 6 at an angle of 45 degrees, the rotating roller 8 is prevented from sliding out of the placement groove 7 when the rotating plate 6 rotates vertically.

[0029] The diameter of the second gear 13 is greater than the diameter of the first gear 12 .

[0030] By adopting the above technical solution and setting the diameter of the second gear 13 to be larger than the diameter of the first gear 12 , it is convenient to control the rotation speed of the bag-making raw material 9 .

[0031] Working principle: When the bag making machine is feeding, the bag making raw material 9 is fixed to the outside of the rotating roller 8, and then the rotating roller 8 is placed inside the placement slot 7. The piston rod of the electric cylinder 10 is contracted to drive the rotating plate 6 to rotate upward, thereby driving the bag making raw material 9 to rotate synchronously with the rotating plate 6, and rotating the rotating roller 8 to the inside of the card slot 15. At this time, the first gear 12 and the second gear 13 are engaged and connected, and then the first gear 12 is driven to rotate by the servo motor 11. The first gear 12 and the second gear 13 are engaged and connected, and the rotating roller 8 is driven to rotate at the same time, thereby performing the unwinding operation on the bag making raw material 9.

Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
