Technical Field

[0001] This utility model relates to the field of composite film production technology, specifically to a feeding device for composite film production. Background Technology

[0002] Composite film refers to a multi-layered film formed by bonding various plastics with paper, metal or other materials through processes such as lamination, extrusion, and co-extrusion. In the production process of composite film, a feeding device is needed to load the material rolls onto the feeder to facilitate the transport of the material rolls.

[0003] Existing feeding devices mostly use a trolley to move the material roll and a lifting mechanism to deliver it to the feeder. However, manual trolley pushing can cause positional deviations, making it difficult for the feeder to lift and rotate the material roll. Therefore, we propose a feeding device for composite film production to solve the problems mentioned above. Utility Model Content

[0023] Please see Figure 1-4 This utility model provides a technical solution: a feeding device for composite film production, comprising: a vehicle body 1, a beam frame 2, a sliding sleeve 3, a connecting plate 4, a turntable 5, a handle 6, a material rack 7, a limit frame 8, a motor 9, a connecting shaft 10, a transmission chain 11, a counterweight 12, a gear plate 13, a claw 14, a fixing sleeve 15, a spring 16, and a connecting rod 17;

[0024] The vehicle body 1 has a beam frame 2 on the right side, and a sliding sleeve 3 is provided on the lower exterior of the beam frame 2. A connecting plate 4 is connected to the left end of the sliding sleeve 3, and a turntable 5 is provided on the upper left side of the connecting plate 4. A handle 6 is connected to the right end of the turntable 5, and a material rack 7 is provided on the top of the turntable 5.

[0025] Motor 9 is located above beam frame 2, and the output end of motor 9 is connected to connecting shaft 10. A transmission chain 11 is provided on the outer side of the middle part of connecting shaft 10, and the left and right ends of transmission chain 11 are connected to connecting plate 4 and counterweight block 12 respectively. A gear plate 13 is connected to the outer end of connecting shaft 10, and a pawl 14 is provided on the right side of gear plate 13. A fixing sleeve 15 is provided on the right end of pawl 14, and a spring 16 is provided at the connection between pawl 14 and fixing sleeve 15. Fixing sleeve 15 is fixedly connected to beam frame 2.

[0026] like Figure 1 , Figure 2 and Figure 3 The connecting plate 4 forms a sliding structure with the beam frame 2 through the sliding sleeve 3, and the turntable 5 forms a rotating structure with the connecting plate 4, which facilitates the stable lifting and lowering of the connecting plate 4. A limit frame 8 is provided on the upper right side of the connecting plate 4, and the limit frame 8 is set in a “︿” shape. The right end of the handle 6 passes through the interior of the limit frame 8, which facilitates the restriction of the position of the handle 6. The connecting plate 4 forms a linkage mechanism with the counterweight 12 through the transmission chain 11, and the counterweight 12 is slidably connected to the beam frame 2, which facilitates the reduction of the load on the motor 9.

[0027] like Figure 2 , Figure 3 and Figure 4The middle gear plate 13 is symmetrically arranged at both ends of the connecting shaft 10, and the pawl 14 and the gear plate 13 form a ratchet and pawl structure, which facilitates the restriction of the connecting shaft 10. The pawl 14 and the fixed sleeve 15 form a telescopic structure, and the individual pawls 14 are connected by a connecting rod 17, which facilitates the retraction of the pawls 14.

[0028] Working principle: When using the feeding device for composite film production, such as Figure 1 As shown, the material roll is placed on the material rack 7. By pushing the car body 1, the car body 1 is moved to the feeding shaft of the feeder. By starting the motor 9, the motor 9 drives the connecting shaft 10 to rotate, thereby driving the transmission chain 11 to move. The connecting plate 4 moves under the action of the transmission chain 11 and the counterweight 12. The connecting plate 4 slides with the beam frame 2 through the sliding sleeve 3, which increases the lifting stability of the connecting plate 4. After the material roll is aligned with the feeding shaft of the feeder, the shaft of the feeder contacts the material roll.

[0029] After the material roll is connected to the feed shaft of the feeder, such as Figure 4 As shown, by manually squeezing the connecting rod 17, the connecting rod 17 drives the chuck 14 to retract, and the chuck 14 separates from the toothed disc 13, causing the connecting plate 4 to fall, and the material rack 7 to separate from the material roll, thereby facilitating the movement of the vehicle body 1.

[0030] When the position of vehicle body 1 deviates, such as Figure 2 As shown, by manually pressing down the lever 6, the lever 6 is separated from the limit frame 8, and the lever 6 is rotated, causing the lever 6 to drive the turntable 5 to rotate, thereby causing the material roll on the material rack 7 to rotate, which facilitates the adjustment of the position of the material roll, and thus facilitates the connection of the material roll with the feeding shaft of the feeder. This is the whole working process of the feeding device for composite film production. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
