Description

Technical Field

[0001] This utility model relates to the field of stacking device technology, specifically a granular product stacking device. Background Technology

[0002] After granular products are packaged in existing technologies, they often need to be stacked to reduce storage space. Common methods include using robotic arms, pneumatic pushers, or stepper motors to neatly stack the products according to preset rules (such as the number of layers and arrangement). After stacking, some equipment can also perform a film wrapping operation to improve storage efficiency.

[0003] In existing stacking devices, when wrapping the film, the device can only wrap the stacked product around the four sides, and cannot provide protection for the top. This has drawbacks, so an improved stacking device for granular products is needed to address this issue. Utility Model Content

[0004] The purpose of this invention is to provide a granular product stacking device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a granular product stacking and packaging device, including a base plate, a rotatable platform movably mounted on the upper end of the base plate via a rotating shaft, a top film coating mechanism for stacking and packaging being mounted on the upper end of the rotatable platform, the top film coating mechanism including a fixed frame, a sliding groove, a slider, a movable frame, an electric push rod, a fixed plate, and a first film roll, the fixed frame being mounted on the upper end of the rotatable platform, the surface of the fixed frame having a sliding groove, the slider being movably engaged with the surface of the fixed frame via the sliding groove, the movable frame being fixedly mounted on the lower end of the slider, the electric push rod being fixedly mounted on the middle of the movable frame, the fixed plate being fixedly mounted on the movable end of the electric push rod, and the first film roll being movably mounted on one side of the fixed plate via a rotating shaft.

[0018] 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.

[0019] Please see Figure 1-3 This utility model provides a technical solution: a granular product stacking and packaging device, comprising a base plate 1, a rotatable platform 16, a top coating mechanism, and an outer coating mechanism.

[0020] The base plate 1 serves as the basic support structure for the entire device. A rotatable platform 16 is movably mounted on its upper end via a rotating shaft. An electric motor is installed inside the base plate 1. The power output shaft of the electric motor is connected to the rotating shaft where the rotatable platform 16 is located. The electric motor can drive the rotatable platform 16 to rotate, thereby driving the stacked bags placed on the platform to rotate.

[0021] The rotatable platform 16 is equipped with a top film covering mechanism for covering the top of the stacked packages. The mechanism includes a fixed frame 2, a slide 3, a slider 4, a movable frame 5, an electric push rod 6, a fixed plate 7, a first film roll 8, as well as components such as a screw 12, a servo motor 13, a slide rod 14, and a sliding sleeve 15.

[0022] Fixed frame and movable frame: A fixed frame 2 is fixedly installed on the upper end of the rotatable platform 16. A groove 3 is opened on the surface of the fixed frame 2. The slider 4 is movably engaged with the fixed frame 2 through the groove 3. The lower end of the slider 4 is fixedly connected to the movable frame 5.

[0023] An electric push rod 6 is fixedly installed in the middle of the movable frame 5. A fixed plate 7 is fixedly connected to the movable end of the electric push rod 6. A first film roll 8 is movably installed on one side of the fixed plate 7 via a rotating shaft. A screw 12 is movably installed in the middle of the fixed frame 2 via a bearing. The upper end of the movable frame 5 is threadedly fitted onto the outer surface of the screw 12. A servo motor 13 is fixedly installed on one side of the surface of the fixed frame 2. The power output shaft of the servo motor 13 is connected to the screw 12 for transmission. By driving the screw 12 to rotate through the servo motor 13, the movable frame 5 and the first film roll 8 can be moved left and right, thereby covering the top of the stacked package with the film on the surface of the first film roll 8.

[0024] Slide rods 14 are fixedly installed on both sides of the upper end of the fixed plate 7, and a sliding sleeve 15 is fixedly installed on the surface of the movable frame 5. The slide rods 14 are movably fitted inside the sliding sleeve 15. By fitting the slide rods 14 into the sliding sleeve 15, the stability of the vertical movement of the fixed plate 7 can be ensured. The extension of the electric push rod 6 can push the fixed plate 7 and the first film roll 8 downward, reducing the height of the first film roll 8 and facilitating its replacement.

[0025] An outer film covering mechanism is provided on one side of the upper end of the base plate 1 for covering the perimeter of the stacked packages with film. This mechanism includes a lifting device 9, a lifting block 10, and a second film roll 11. The lifting device 9 is fixedly installed on one side of the upper end of the base plate 1, and the lifting block 10 is provided on one side of the surface of the lifting device 9. The lifting device 9 can drive the lifting block 10 to move up and down, and the second film roll 11 is movably mounted on the surface of the lifting block 10 via a rotating shaft.

[0026] Working principle: This device adds a top film covering unit to the traditional stacking and wrapping device. It first covers the top of the stacked packages with film, then wraps the sides, greatly improving the protective effect after stacking. Specific operation is as follows:

[0027] Top lamination: When laminating the top of the stacked packages, pull the film on the surface of the first film roll 8 to adhere the film to the surface of the stacked packages. The adhesion should not only cover the top of the stacked packages but also extend to the upper part of one side of the stacked packages (e.g., Figure 2 (As shown, this adhesion depth is suitable). Subsequently, the servo motor 13 drives the screw 12 to rotate, driving the moving frame 5 and the first film roll 8 to move towards the lifting device 9, covering the top of the stacked packages with the film on the surface of the first film roll 8. Afterwards, the worker cuts the film on the surface of the first film roll 8, so that the cut end also adheres to the surface of the stacked packages.

[0028] Side lamination: During side lamination of the stacked packages, the film on the surface of the second film roll 11 is adhered to the upper end of the perimeter of the stacked packages, so that the film covers the top film that was just set. Then, the rotatable platform 16 is rotated by a motor, which in turn rotates the stacked packages, causing the stacked packages to wrap around the film on the surface of the second film roll 11, completing the film wrapping work around the stacked packages. During this process, the second film roll 11 should release the film while moving downward under the action of the lifting device 9, finally completing the entire lamination work.
