Technical Field

[0001] The utility model relates to the technical field of emulsion explosive packaging film recovery, in particular to a filling and packaging composite film coiling device. Background Art

[0002] In the daily production process of emulsion explosives, due to the different inner and outer diameter thicknesses of the filling and packaging composite films produced by different suppliers, the sensing device for replacing the filling and packaging composite film in the charging machine has deviations when sensing the inner diameter of the filling and packaging composite film; at the same time, there may be shaking during the operation of the equipment, resulting in low sensing accuracy, so that the film changing equipment of the charging machine fails to use up the filling and packaging composite film as much as possible and then switch to the new filling and packaging composite film, making it difficult to continue to use the remaining filling and packaging composite film. Over time, this leads to waste of raw materials and high production costs. In addition, the remaining filling and packaging composite film rolls need to be destroyed, which increases the work intensity of the workers. Therefore, conducting research in this area and increasing the utilization rate of filling and packaging composite films have important practical significance for reducing costs and increasing efficiency in the long run.

[0030] A second rotating shaft 3, the second rotating shaft 3 is rotatably connected to the housing 1, the second rotating shaft 3 is parallel to the first rotating shaft 2, and the second rotating shaft 3 is used for sleeve-connecting the composite film roll 4 for centralized recovery;

[0034] In the above implementation manner, the controller can select a single-chip microcomputer, which converts the torque signal into a level signal. For example, when the torque sensor senses that the torque is higher than a preset threshold, a high level is input to the single-chip microcomputer, and a low level is output accordingly. The control circuit of the motor is disconnected through a conventional relay switch circuit, thereby achieving the purpose of automatic shutdown.

The innovation of the present utility model is to set the heat sealing mechanism at a specific position of the casing 1 to facilitate the heat sealing and bonding of the ends of the two composite film rolls 4. For example, the fractures of the two composite films are overlapped first. In one of the heat sealing mechanisms, the overlapping fractures of the two composite films are clamped by two clamping arms in a high-temperature state for hot-melt bonding.

[0039] As a preferred embodiment, the first rotating shaft 2 is an inflatable shaft.

[0040] In the above embodiments, the inflatable shaft is an existing structure, and its specific principle will not be described in detail here.

[0041] In the above embodiment, when replacing the next composite film roll 4 to be recycled, the second rotating shaft 3 is always in an inflated and tightened state. The broken end of the film roll is first overlapped with the film roll port on the second rotating shaft 3, and after being heat-sealed by a heat sealing mechanism, the composite film roll 4 to be recycled is sleeved on the first rotating shaft 2, and the drive motor 51 is started through air expansion and tightening to carry out the winding and recycling of the composite film.
