Description

Technical Field

[0001] This utility model mainly relates to the field of automatic film roll loading technology, specifically to an automatic film loading machine. Background Technology

[0002] A heat sealing machine is a device that heats and closes product packaging films to form a cylindrical shape, thereby achieving a sealed state. Existing heat sealing machines typically have two film roll positions, with the two rolls alternating to achieve continuous film supply; that is, when one roll is used up, the other roll takes over to continue supplying film. However, the film rolls in existing heat sealing machines are usually installed manually, which is inefficient. Utility Model Content

[0003] To address the shortcomings and deficiencies of current technology, this utility model proposes an automatic film-applying machine. The technical solution is as follows:

[0004] This utility model proposes an automatic film application machine, including a film storage device and a film application device;

[0005] The film storage device includes a film storage tray for placing film rolls. A film picking rod and a first film clamping mechanism are provided on one side of the film storage tray. The film extending from the film roll passes through the film picking rod on one side and is clamped by the first film clamping mechanism.

[0006] The film-attaching device includes a film-attaching support, which is provided with a film-attaching horizontal shaft, a film-supporting support, and a second film-clamping mechanism. A pusher tube capable of axial movement is sleeved on the film-attaching horizontal shaft. The film-attaching support is connected to a drive mechanism to drive the film-attaching support to move laterally along the guide rail, move vertically along the vertical direction of the rotating column, and rotate around the axis of the rotating column, thereby realizing the lateral and vertical movement and rotation of the film-attaching horizontal shaft, the film-supporting support, and the second film-clamping mechanism.

[0007] The film roll placed on the film storage tray is concentric with the film hanging axis, so that the film hanging axis can be inserted into the film roll core when moving laterally. When the film hanging axis is inserted into the film roll core, the film support bracket extends into the lower side of the film on the film picking rod. At the same time, the first film clamping mechanism releases the film and the second film clamping mechanism clamps the film released by the first film clamping mechanism.

[0008] As a preferred embodiment of the above technical solution, the driving mechanism includes a fixedly mounted sliding frame, a slide rail mounted on the sliding frame, a slide table mounted on the slide rail, a rack mounted on one side of the slide rail, a drive motor reducer mounted on the slide table, a gear mounted on the output shaft of the drive motor reducer, the gear meshing with the rack to drive the slide table to move laterally along the rack, a hollow turntable mounted on the slide table, the hollow turntable connected to a rotating column to drive the rotating column to rotate, an electric cylinder fixed on one side of the rotating column, the electric cylinder connected to a lifting support, and the lifting support connected to an upper membrane support.

[0009] As a preferred embodiment of the above technical solution, the pusher tube is connected to a pusher nut sleeved on the film hanging horizontal shaft, the pusher nut is connected to a pusher screw inside the film hanging horizontal shaft, and the pusher screw is connected to a drive motor reducer on the upper film support.

[0010] As a preferred embodiment of the above technical solution, the upper surface of the membrane support bracket has a transverse through groove.

[0011] As a preferred embodiment of the above technical solution, the film clamping mechanism includes a film clamping bracket, the film clamping bracket having a groove, and a film clamping cylinder provided on one side of the groove, so that the film clamping cylinder presses the film tightly when the film is inserted into the groove.

[0012] As a preferred embodiment of the above technical solution, the membrane storage device and the membrane loading device are two sets, and the two sets are used alternately.

[0013] The automatic film application method of the automatic film application machine includes the following steps:

[0014] 1) The film extending from the film roll is clamped by the first film clamping mechanism after passing through the film picking rod on one side;

[0015] 2) Set the film mounting horizontal axis to move laterally to insert into the film roll core. When the film mounting horizontal axis is inserted into the film roll core, the film support bracket extends into the lower side of the film on the film picking rod. At the same time, the first film clamping mechanism releases the film and the second film clamping mechanism clamps the film released by the first film clamping mechanism.

[0016] 3) Set the drive mechanism to drive the film mounting horizontal axis, film support bracket and second film clamping mechanism to move upward to lift the film roll. At this time, the film support bracket supports the film on the film lifting rod and the second film clamping mechanism clamps the film released by the first film clamping mechanism.

[0017] 4) After the drive mechanism drives the film hanging horizontal axis, film support bracket and second film clamping mechanism to move laterally by a preset distance, rotate so that the film roll axis is aligned with the film roll axis on the heat sealing machine. After moving laterally closer to the heat sealing machine, the push tube pushes the film roll to push the film roll onto the film roll axis of the heat sealing machine. At this time, the second film clamping mechanism releases the clamped film.

[0018] This invention proposes an automatic film loading machine. A film-hanging horizontal shaft, a film-supporting bracket, and a second film-clamping mechanism move laterally under the drive of a driving mechanism. When the film-hanging horizontal shaft is inserted into the film roll core, the film-supporting bracket extends to the underside of the film on the film-picking rod. At this point, the first film-clamping mechanism releases the film, and the second film-clamping mechanism clamps the film released by the first clamping mechanism. Subsequently, the driving mechanism drives the aforementioned components to move upwards, lifting the film roll, while the film-supporting bracket supports the film on the film-picking rod. After the driving mechanism drives the aforementioned components to move laterally a preset distance, it rotates to align the film roll core with the film roll shaft on the heat-sealing machine. Further lateral movement closer to the heat-sealing machine, and a pusher tube pushes the film roll onto the film roll shaft of the heat-sealing machine. At this point, the second film-clamping mechanism releases the clamped film. This mechanism enables automatic film loading, effectively improving film loading efficiency. Attached Figure Description

[0028] The film storage device 1 includes a film storage tray 1-1, which is used to place film rolls. A film picking rod 1-2 and a first film clamping mechanism 1-3 are provided on one side of the film storage tray. The film extending from the film roll passes through the film picking rod on one side and is clamped by the first film clamping mechanism.

[0029] The film-mounting device 2 includes a film-mounting support 2-1, on which a film-mounting horizontal shaft 2-2, a film-supporting support 2-3, and a second film-clamping mechanism 2-4 are provided. A pusher tube 2-5 capable of axial movement is sleeved on the film-mounting horizontal shaft. The film-mounting support is connected to a drive mechanism to drive the film-mounting support to move laterally along the guide rail, move vertically along the vertical direction of the rotating column, and rotate around the axis of the rotating column, thereby realizing the lateral and vertical movement and rotation of the film-mounting horizontal shaft, the film-supporting support, and the second film-clamping mechanism.

[0030] The film roll placed on the film storage tray is concentric with the film hanging axis, so that the film hanging axis can be inserted into the film roll core when moving laterally. When the film hanging axis is inserted into the film roll core, the film support bracket extends into the lower side of the film on the film picking rod to support the film on the film picking rod. At the same time, the first film clamping mechanism releases the film and the second film clamping mechanism clamps the film released by the first film clamping mechanism.

[0031] The driving mechanism includes a fixed sliding frame 2-6, a slide rail 2-7 on the sliding frame, a slide table 2-8 on the slide rail, a rack 2-8 on one side of the slide rail, a drive motor reducer 2-10 on the slide table, a gear on the output shaft of the drive motor reducer, the gear meshing with the rack to drive the slide table to move laterally along the rack, a hollow turntable 2-11 on the slide table, the hollow turntable connected to a rotating column 2-12 to drive the rotating column to rotate, an electric cylinder 2-13 fixed on one side of the rotating column, the electric cylinder connected to a lifting support 2-14, and the lifting support connected to an upper membrane support 2-1. Alternatively, the driving mechanism could also be in the form of a robotic arm, which will not be elaborated upon here.

[0032] The push tube is connected to the push nut 2-15 sleeved on the film hanging horizontal shaft. The push nut is connected to the push screw inside the film hanging horizontal shaft. The push screw is connected to the drive motor reducer on the upper film support.

[0033] The upper surface of the film support bracket 2-3 has a transverse through groove. When the film support bracket moves up and down, the groove reduces the collision between the film support bracket 2-3 and the film lifting rod 1-2.

[0034] The film clamping mechanism includes a film clamping bracket, which has a groove. A film clamping cylinder is provided on one side of the groove so that when the film is inserted into the groove, the film clamping cylinder presses the film tightly.

[0035] The automatic film application method of the automatic film application machine includes the following steps:

[0036] 1) The film extending from the film roll is clamped by the first film clamping mechanism after passing through the film picking rod on one side;

[0037] 2) Set the film mounting horizontal axis to move laterally to insert into the film roll core. When the film mounting horizontal axis is inserted into the film roll core, the film support bracket extends into the lower side of the film on the film picking rod. At the same time, the first film clamping mechanism releases the film and the second film clamping mechanism clamps the film released by the first film clamping mechanism.

[0038] 3) Set the drive mechanism to drive the film mounting horizontal axis, film support bracket and second film clamping mechanism to move upward to lift the film roll. At this time, the film support bracket supports the film on the film lifting rod and the second film clamping mechanism clamps the film released by the first film clamping mechanism.

[0039] 4) The drive mechanism drives the film hanging axis, film support bracket and second film clamping mechanism to move laterally by a preset distance and then rotates so that the film roll axis is aligned with the film roll axis on the heat sealing machine. After moving laterally closer to the heat sealing machine, the push tube pushes the film roll to the film roll axis of the heat sealing machine. At this time, the second film clamping mechanism releases the clamped film, and so on.

[0040] This invention proposes an automatic film loading machine that can automatically load film rolls, effectively improving film loading efficiency.
