[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figure 1-2 This utility model provides a technical solution: an automatic bag-making machine feeding mechanism, comprising: a frame 1; two rotating arms 2, rotatably mounted on the frame 1; a feeding seat 3 disposed at the end of the rotating arm 2; a feeding roller 4 placed between the two feeding seats 3; a limiting component 5 disposed on the rotating arm 2 for limiting the feeding roller 4 placed on the feeding seat 3; and a lifting component 6 disposed on the frame 1 for simultaneously driving the two rotating arms 2 to rotate, lifting the feeding roller 4 to the installation position. When the film roll on the outer side of the feeding roller 4 is used up... When replacement is required, the lifting assembly 6 is activated to move the rotating arm 2, causing it to rotate under its own weight. The rotation of the rotating arm 2 drives the feeding seat 3 to descend to the feeding position. The limiting assembly 5 is then activated to release the limit and the feeding roller 4 is removed for replacement. After replacement, the limiting assembly 5 is activated to limit the feeding roller 4, and the lifting assembly 6 is activated to move the rotating arm 2 in the opposite direction and lift it to the installation position. During the installation process, there is no need for manual lifting of the material roll, avoiding the problem of operators slipping and injuring themselves or damaging the material roll.
[0027] Specifically, the feeding seat 3 includes a placement port 3-1 located at the end of the rotating arm 2. The placement port 3-1 is configured as an arc-shaped opening that matches the rotating shaft end of the feeding roller 4. The inner wall of the placement port 3-1 is provided with several evenly distributed bearing rollers 3-2. The bearing rollers 3-2 are used to support the rotating shaft end of the feeding roller 4.
[0028] Specifically, the limiting component 5 includes an L-shaped connecting plate 5-1 rotatably mounted on the side wall of the rotating arm 2. A cylinder 5-2 is hinged to the rotating arm 2. The output end of the cylinder 5-2 is hinged to the end of the L-shaped connecting plate 5-1 away from the feeding seat 3. A limiting roller 5-3 is provided at the end of the L-shaped connecting plate 5-1 near the feeding seat 3. In use, the cylinder 5-2 is started to drive the L-shaped connecting plate 5-1 to rotate, so that the limiting roller 5-3 on the L-shaped connecting plate 5-1 is close to the opening end of the feeding seat 3 for limiting, ensuring the stability of the feeding roller 4 during the lifting process and effectively preventing the feeding roller 4 from falling off during the lifting process.
[0029] Specifically, the lifting assembly 6 includes a screw module 6-1 mounted on the frame 1. The movable end of the screw module 6-1 is provided with a movable platform 6-2. Both the front and rear ends of the movable platform 6-2 are provided with lifting plates 6-3. The lower end of the rotating arm 2 is provided with an abutting roller 6-4 that abuts against the lifting plate 6-3. In use, the screw module 6-1 is activated to drive the movable platform 6-2 and the lifting plate 6-3 to move. As the lifting plate 6-3 moves, the abutting roller 6-4 moves relative to the lifting plate 6-3, thereby driving the rotating arm 2 to rotate.
[0030] Specifically, the lifting plate 6-3 includes a first plane 6-3-1, a second plane 6-3-2, and an inclined surface 6-3-3. The inclined surface 6-3-3 is located between the first plane 6-3-1 and the second plane 6-3-2. The intersection of the first plane 6-3-1, the second plane 6-3-2, and the inclined surface 6-3-3 is set as an arc-shaped surface. The abutting roller 6-4 abuts against the first plane 6-3-1. The feeding seat 3 on the rotating arm 2 is in the feeding position. The first plane 6-3-1 is used to limit the rotation range of the rotating arm 2. The feeding seat 3 is positioned to feed material. The contact roller 6-4 contacts the inclined surface 6-3-3. When the lifting plate 6-3 moves, the rotating arm 2 rotates to lift the feeding seat 3. As the lifting plate 6-3 moves, the contact roller 6-4 slides relative to the inclined surface 6-3-3, thereby driving the swing arm 2 to rotate and lifting the feeding seat 3. The contact roller 6-4 contacts the second plane 6-3-2. The feeding seat 3 on the rotating arm 2 is in the installation position, which facilitates the operator to connect the feeding roller 4 to the power end of the device.
[0031] Working principle: When the feeding roller 4 needs to be replaced during operation, the lifting component 6 is activated to move and cause the rotating arm 2 to rotate under its own weight. The rotation of the rotating arm 2 drives the feeding seat 3 to descend to the feeding position. The limiting component 5 is opened and the feeding roller 4 is removed for replacement. After the replacement is completed, the limiting component 5 is activated to limit the feeding roller 4, and the lifting component 6 is activated to move and cause the rotating arm 2 to rotate in the opposite direction and be lifted to the installation position.
