Description

Technical Field

[0001] This utility model relates to the technical field of film rolling machine equipment, specifically a film roll holder for a film rolling machine. Background Technology

[0002] Wrapping machines are mainly used for packaging palletized products. When wrapping products, the plastic film needs to be stretched to easily cover the outside of the palletized product. Currently, before an automatic wrapping machine starts operating, a film roll needs to be loaded onto the machine. The film roll is gradually consumed, and when it runs out, the automatic wrapping machine stops. Workers need to replace the film roll on the machine. Because the film roll is heavy and needs to be accurately placed in a specific position on the machine, the empty film roll is removed, and a new film roll is installed. The entire replacement process is often quite complex, requiring workers to use forklifts or even overhead cranes to move the film. This not only poses a certain danger but also makes it difficult to place the film in the target position perfectly on the first try. The back-and-forth adjustments result in significant equipment downtime, affecting the continuous operating efficiency of the wrapping machine. Utility Model Content

[0003] To address the problems mentioned in the background art, this utility model provides a film roll frame for a film wrapping machine, including a frame. The frame has an entrance on its front side, and entrance tracks extend inward from the entrance on both the left and right sides of the frame. The front ends of the entrance tracks are inclined upward, and the ends of the two entrance tracks are inclined downward and connected to film roll constraint units. Each film roll constraint unit includes a film roll constraint plate, a push rod, and a push rod motor. The lower end of the film roll constraint plate is connected to the push rod, and the lower end of the push rod is connected to the push rod motor. The upper ends of the two film roll constraint plates abut against both ends of the film roll shaft. A film roll is sleeved on the film roll shaft. A sensor is provided above the film roll in the entrance track. An exit track is provided on one side of the frame at the film roll constraint unit. The exit track is inclined downward. A transmission roller is provided above the film roll, and a film pressing roller is provided above the transmission roller. A film sealing and cutting device is provided on one side of the film pressing roller.

[0004] The rack is equipped with a data interaction unit, and the data interaction unit is equipped with an indicator light.

[0005] The frame is equipped with a forklift parking signal unit.

[0006] A speed sensor is provided on one side of the film roll, and a speed sensor is provided on the film pressing roller.

[0007] The cross-section of the membrane roll constraint plate is obtuse-angled V-shaped.

[0008] The upper surface of the membrane roll constraint tray is provided with a wear-resistant layer.

[0009] Compared with the prior art, this utility model facilitates loading full film rolls and unloading empty film rolls, real-time calculation and monitoring of remaining film rolls, shortens downtime of the film wrapping machine, improves the automation level of the film wrapping system, and enhances the safety of the production process.

[0011] The present invention will be further described below with reference to the accompanying drawings.

[0012] like Figure 1 A film roll holder for a film wrapping machine includes a frame 1. The frame 1 has an entrance on its front side. Entrance rails 2 extend inward from the entrance on both the left and right sides of the frame 1. The front ends of the entrance rails 2 are inclined upwards, and the ends of the two entrance rails 2 are inclined downwards and each connected to a film roll constraint unit 3. The film roll constraint unit 3 includes a film roll constraint support plate 6, a push rod 7, and a push rod motor 8. The lower end of the film roll constraint support plate 6 is connected to the push rod 7, and the lower end of the push rod 7 is connected to the push rod motor 8. The push rod motor 8 drives the film roll constraint support plate 6 through the push rod 7. The machine moves between the support position and the release position. The upper ends of the film roll constraint plates 6 on both sides abut against the two ends of the film roll shaft 5. The film roll 4 is sleeved on the film roll shaft 5. A sensor 13 is provided above the film roll 4 in the inlet track. The sensor 13 is used to detect whether the film roll shaft 5 is in place. An outlet track 9 is provided on one side of the frame 1 at the film roll constraint unit 3. The outlet track 9 is inclined downward. A transmission roller 10 is provided above the film roll 4. A pressure roller 11 is provided above the transmission roller 10. A sealing and cutting device 12 is provided on one side of the pressure roller 11.

[0013] A data interaction unit 14 is provided on the rack 1. The data interaction unit 14 is equipped with an indicator light for displaying the device status and conducting data communication.

[0014] The frame 1 is equipped with a forklift parking signal unit 15, which is used to receive the automatic forklift arrival signal.

[0015] A speed sensor 16 is provided on one side of the film roll 5, and a speed sensor 17 is provided on the film pressing roller 11 to detect its rotation speed.

[0016] The membrane roll constraint plate 6 has an obtuse V-shaped cross section, which facilitates the guidance and positioning of the membrane roll 4.

[0017] The upper surface of the membrane roll constraint tray 6 is provided with a wear-resistant layer to improve its service life.

[0018] After the film wrapping machine starts, sensor 13 detects whether there is a film roll 5. If not, it communicates through data interaction unit 14 to enable forklift 18 to transport a new film roll. Forklift 18 delivers the new film roll to the entrance of entrance track 2. Under the action of gravity, film roll 5 automatically slides into entrance track 2 and is caught and limited by film roll constraint plate 6. Film wrapping begins, and the film is pulled through drive roller 10, pressure roller 11, and sealing and cutting device 12. Speed ​​sensor 2 17 detects the speed of pressure roller 11, and speed sensor 16 detects the speed of film roll 5. If pressure roller 11 is detected to be rotating normally but film roll 5 is not rotating, it indicates an abnormality in film pressing, and feedback is sent to data interaction unit 14. If both are detected to be rotating, the system is in normal condition, and the remaining amount of film roll 4 is calculated in real time. When film roll 4 is detected to be almost used up, forklift 18 is dispatched through data interaction unit 14 to pick up the empty roll. After forklift 18 arrives, forklift stop signal unit 15 sends a feedback signal. Upon receiving the signal, the film rolling machine controls the pusher motor 8 to retract the pusher 7, causing the film roll constraint plate 6 to rotate downwards to the release position. The unconstrained empty film roll 5, under the influence of gravity, automatically slides out along the downward-sloping exit track 9, is caught by the forklift, and transported away. Sensor 13 detects that the film roll 5 has slid out, controls the pusher motor 8 to reset the film roll constraint plate 6, and controls the forklift 18 to transport a new film roll, starting the next cycle.
