Description

Technical Field

[0001] This utility model belongs to the technical field of bag making machine conveying limit device, specifically a bag making machine conveying limit device that can prevent shaking. Background Technology

[0002] Packaging bags are bags used to package various items, facilitating their storage and transportation during distribution. Packaging bags are typically made from packaging film. The packaging film is fed into a bag-making machine via a feeding device, traction device, and guide rollers, and then conveyed to a hot-pressing device for bag making.

[0003] A search revealed that patent CN218892293U discloses a conveying limiting device for a bag-making machine. The device includes a base, with symmetrically distributed columns on one side of the upper wall of the base. A roller is mounted on the opposite side of two of the columns. A limiting mechanism is located on one side of the roller on the upper wall of the base. The limiting mechanism contains a pressing mechanism and includes two fixed plates, both fixedly connected to the base. A top plate is fixedly connected to the top of both fixed plates. This invention, by setting a limiting mechanism, utilizes a second motor within the limiting mechanism to drive a bidirectional lead screw to rotate. The bidirectional lead screw drives two threaded sleeves to move, and the two threaded sleeves, through a connecting rod, drive the limiting plate to move. The limiting plate can move on the outer wall of the guide roller, thereby preventing the packaging film from deviating and ensuring a stable output path for the packaging film.

[0004] When using existing bag-making machine conveyor limiting devices, the packaging film is prone to shaking during conveying, which can lead to damage to the packaging film. Summary of the Invention

[0005] The purpose of this invention is to provide a sway-proof conveying limit device for a bag-making machine, in order to solve the problems mentioned in the background art.

[0006] In view of this, the present invention provides a bag making machine conveying limiting device that can prevent shaking, including a conveying frame, a limiting frame fixedly connected to the inner wall of the conveying frame, a spring fixedly connected to the inner wall of the limiting frame, a lever fixedly connected to one end of the spring, a connecting plate fixedly connected to both ends of the lever, a connecting groove opened on the outer wall of the connecting plate, a connecting column movably connected in the groove, a limiting frame fixedly connected to one end of the connecting column, a limiting rod fixedly connected to the inner wall of the limiting frame passing through the inside of the limiting frame, and limiting rollers screwed to both ends of the limiting frame.

[0007] Based on the above structure, the spring drives the connecting plates at both ends of the lever to slide under its own elastic force. The sliding of the connecting plates causes the connecting groove to slide synchronously. The sliding of the connecting groove drives the limiting frame to slide along the outer wall of the limiting rod through the connecting column. The sliding of the limiting frame causes the limiting roller to fit against the outer edge of the packaging film, which plays a protective role for the packaging film and prevents the packaging film from shaking during transportation.

[0008] Preferably, the limiting frame is provided in two sets. In this embodiment, it can limit the two sides of the packaging film.

[0009] Preferably, the limiting frame forms a sliding structure with the limiting rod through the connecting groove and the connecting column. In this embodiment, the sliding of the connecting groove drives the limiting frame to slide along the outer wall of the limiting rod through the connecting column, thereby realizing the control operation of the sliding of the limiting frame.

[0010] Preferably, the outer wall of the limiting roller is provided with anti-slip texture. In this embodiment, the limiting frame slides and drives the limiting roller to fit against the outer edge of the packaging film, which protects the packaging film and prevents the packaging film from shaking during transportation.

[0011] Preferably, a servo motor is fixedly connected to one side of the inner wall of the conveying frame, and a rotating plate is fixedly connected to the output end of the servo motor. A screw is provided on the inner wall of the rotating plate, and a threaded slider is threadedly connected to the outer wall of the screw. A telescopic plate is fixedly connected to the outer wall of the threaded slider. A swing plate that is screwed onto the inner wall of the conveying frame is movably connected to one end of the telescopic plate. A swing guide groove is provided at the connection between the swing plate and the telescopic plate. A movable roller is screwed onto the outer wall of the swing plate, and a fixed roller that is screwed onto the inner wall of the conveying frame is provided above the movable roller. In this embodiment, the rotation of the rotating plate drives the telescopic plate to rotate synchronously. The telescopic plate drives the swing plate to swing back and forth through the swing guide groove, thereby adjusting the distance between the movable roller and the fixed roller, which facilitates sealing the packaging film. At the same time, rotating the screw causes the screw to rotate and drive the telescopic plate to slide along the outer wall of the rotating plate through the threaded slider. By adjusting the relative length of the telescopic plate and the rotating plate, the swing angle of the swing plate is adjusted, thereby adjusting the tension of the packaging film.

[0012] Preferably, the swing plate forms a reciprocating swing structure with the conveying frame through the rotating plate and the telescopic plate. In this embodiment, the rotating plate rotates and drives the telescopic plate to rotate synchronously. The telescopic plate drives the swing plate to swing back and forth through the swing guide groove, thereby realizing the reciprocating swing operation of the swing plate.

[0013] Preferably, the movable rollers and fixed rollers are distributed in an "M" shape, and the movable rollers are equidistantly distributed along the swing plate. In this embodiment, the telescopic plate drives the swing plate to swing back and forth through the swing guide groove, thereby adjusting the distance between the movable rollers and the fixed rollers, which facilitates sealing the packaging film. At the same time, the swing angle of the swing plate is adjusted by adjusting the relative length of the telescopic plate and the rotating plate, thereby adjusting the tension of the packaging film.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model is equipped with a swing plate. The rotation of the rotating plate drives the telescopic plate to rotate synchronously. The telescopic plate drives the swing plate to swing back and forth through the swing guide groove, thereby adjusting the distance between the fixed rollers and the movable rollers, which facilitates sealing the packaging film. At the same time, the screw rotates, and the screw rotates through the threaded slider to drive the telescopic plate to slide along the outer wall of the rotating plate. By adjusting the relative length of the telescopic plate and the rotating plate, the swing angle of the swing plate is adjusted, thereby realizing the adjustment of the tension of the packaging film.

[0016] 2. This utility model is equipped with a limiting roller. Under the action of its own elastic force, the spring drives the connecting plates at both ends of the lever to slide. The sliding of the connecting plates drives the connecting groove to slide synchronously. The sliding of the connecting groove drives the limiting frame to slide along the outer wall of the limiting rod through the connecting column. The sliding of the limiting frame drives the limiting roller to fit against the outer edge of the packaging film, which plays a protective role for the packaging film and prevents the packaging film from shaking during transportation.
