Description

Technical Field

[0001] The utility model relates to the technical field of film coating machines, in particular to a film placing frame for a film coating machine. Background Art

[0002] At present, film wrapping machines, also called film wrapping machines or winding machines, play an important role in the packaging machinery industry. Film wrapping machines can effectively prevent damage to goods during transportation by wrapping thin films, and play a role in dustproof, moisture-proof and cleaning, ensuring the safety and integrity of goods during storage and transportation. The film placing rack is a bracket for placing rolled film, and the film of the rolled film is connected to the film wrapping machine to convey the film body to the film wrapping machine. The existing film placing rack is composed of a film placing rod, a turntable base and a top limiting structure. The inner core of the rolled film cannot be completely in contact with the film placing rod. During use, the inner core hits the film placing rod to generate very loud vibration and noise. The top limiting structure is used to prevent the rolled film from separating from the film placing rod. The top limiting structure needs to be operated when replacing the rolled film. It is very inconvenient for production personnel to change the film, and it is urgently needed to be improved. Therefore, we propose a film placing rack for a film wrapping machine.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Embodiment 1, as Figure 1-3As shown, the utility model provides a technical solution: a film placing frame of a coating machine, comprising a bottom frame 1, a film placing rod 7, and a driving motor 12 for driving the film placing rod 7 to rotate, a shaft rod 13 is fixedly arranged at the bottom end of the film placing rod 7, and the motor shaft of the driving motor 12 is coaxially connected with the bottom end of the shaft rod 13 through a coupling, a cavity is opened inside the film placing rod 7, a through groove is opened on the outer side of the bottom of the film placing rod 7, a clamping block 8 is inlaid in the through groove, an adjusting rod 9 is threadedly connected inside the film placing rod 7, a conical cylinder 14 for pushing the clamping block 8 to move horizontally is fixedly arranged at the bottom of the adjusting rod 9, and the driving motor 12 is fixed to the bottom layer inside the bottom frame 1.

[0019] In a specific embodiment of the present invention, the driving motor 12 is composed of a reducer and a motor. In order to adapt to the appearance of the driving motor 12, the bottom right side of the bottom frame 1 is designed to be protruding, and the controller 3 is designed to be a large button. The operator controls the start and stop of the driving motor 12 by contacting the button with his foot. A ball 10 is arranged between the truncated pedestal seat A6 and the truncated pedestal seat B5 to support the rotation of the truncated pedestal seat A6 and the film-releasing rod 7. There are four clamping blocks 8, which are distributed around the outer side of the bottom of the film-releasing rod 7. The clamping block 8 is provided with an inclined surface on the side facing the conical cylinder 14. When the conical cylinder 14 moves downward, the clamping block 8 can be pushed to move toward the side away from the conical cylinder 14. When the inner core of the rolled film is inlaid with the film-releasing rod 7, but the inner core is not in contact with the film-releasing rod 7, the clamping block 8 can be made to be in close contact with the inner core of the rolled film by rotating the adjusting rod 9, and the rolled film is driven to rotate at a uniform speed by driving the film-releasing rod 7 to rotate by the driving motor 12, so that the film of the rolled film can be easily unfolded for use.

[0020] In the preferred technical solution, a truncated pedestal seat A6 is fixedly provided at the connection between the film placing rod 7 and the shaft rod 13, and a truncated pedestal seat B5 is fixedly provided on the top of the bottom frame 1. Concave annular grooves 11 are provided at the bottom of the truncated pedestal seat A6 and the top of the truncated pedestal seat B5. Balls 10 are embedded in the concave annular grooves 11. The balls 10 are used to support the rotation of the truncated pedestal seat A6 and the film placing rod 7 to ensure that the film placing rod 7 can still rotate smoothly after placing the rolled film.

[0021] In the preferred technical solution, a cover plate 2 is detachably mounted on the front surface of the bottom frame 1 by bolts, and a controller 3 for controlling the start and stop of the drive motor 12 is fixedly arranged on the surface of the cover plate 2. The controller 3 is used to control the start and stop of the drive motor 12. The controller 3 is designed as a large button and is positioned relatively low. The operator can control the start and stop of the drive motor 12 by contacting the button with his feet, freeing up his hands to unfold the film of the roll.

[0022] In the preferred technical solution, heat dissipation holes 4 for heat dissipation are fixedly provided on both sides of the bottom frame 1. The heat dissipation holes 4 are used for ventilation and heat dissipation of the drive motor 12, so that the working environment temperature of the drive motor 12 is within a normal range.

[0023] In the preferred technical solution, a conical head 701 is integrally formed at the top of the film unloading rod 7. The bottom diameter of the conical head 701 is consistent with the outer ring diameter of the film unloading rod 7. The top diameter of the conical head 701 is half of the bottom diameter of the conical head 701. The conical head 701 is provided to facilitate guiding the rolled film through the top of the film unloading rod 7.

[0024] In the preferred technical solution, the top of the adjusting rod 9 extends to above the top of the conical head 701 , and a rotating disk is fixedly provided on the top of the adjusting rod 9 , and the rotating disk facilitates the rotation of the adjusting rod 9 .

[0025] In summary, the present embodiment provides a film unloading rack for a film coating machine. Through the structural design of the film unloading rod, the film unloading rod is in full contact with the inner core of the film roll. Then, the film roll is driven to rotate by electricity, replacing the traditional manual rotation of the film roll to unfold the film, thereby improving the efficiency of unfolding the film roll. At the same time, the structural design of the film unloading rod facilitates the disassembly and assembly of the film roll.
