Abstract
Description
Technical Field
[0001] This utility model belongs to the field of packaging technology, and in particular relates to a shaking bag device. Background Technology
[0002] During the filling process of packaging bags, this tapping method is mostly used to continuously tap the packaging bag from the side to make the packaged contents fall down, which facilitates the subsequent sealing of the packaging bag. However, this tapping method has many drawbacks. First, it can only tap a local area, and the tapping frequency is low, which means that the packaged contents in other parts of the packaging bag do not reach the required effect. Since the packaging bag is suspended on the discharge hopper with its bottom hanging in the air during the tapping process, the packaging bag will sway back and forth during the tapping process. In the end, when the packaging bag is put down after filling, it often falls over due to the unstable center of gravity, which will cause a major production accident. Utility Model Content
[0003] (I) Purpose of the utility model
[0004] In order to overcome the above shortcomings, the purpose of this utility model is to provide a shaking bag device to solve the above technical problems.
[0005] (II) Technical Solution
[0006] To achieve the above objectives, the technical solution provided in this application is as follows:
[0007] A shaking bag device includes a weighing mechanism, a clamping belt mechanism on the outlet of the weighing mechanism, a packaging bag being installed on the outlet through the clamping belt mechanism, a vibrating platform being provided directly below the outlet, and a lifting mechanism being provided at the bottom of the vibrating platform.
[0008] Preferably, the clamping belt mechanism includes a belt fitted over the discharge port, with both ends of the belt connected to a clamping cylinder. The packaging bag is installed between the belt and the discharge port, and the belt is tightened or loosened from the discharge port under the action of the clamping cylinder.
[0009] Preferably, the vibration platform is folded down on all four sides.
[0010] Preferably, a vibration motor is provided at the bottom of the vibration platform.
[0011] Preferably, the lifting mechanism includes guide components located at the four corners of the bottom of the vibration platform and a lifting cylinder located at the center of the vibration platform. Both the lifting cylinder and the guide components are connected to the vibration platform via universal floating joints.
[0012] Preferably, the guide assembly includes a bottom guide base and a guide rod that slides up and down within a sliding groove of the guide base.
[0013] Preferably, the weighing mechanism is provided with a weighing hopper at the upper end of the discharge port.
[0014] Beneficial effects:
[0015] 1. The vibrating platform is a flat plate vibrating system. A thick iron plate is designed as the vibrating platform at the bottom of the packaging bag's working position. During operation, the bottom of the packaging bag rests on the platform surface. The bag is vibrated during the filling process, resulting in a flat bottom after filling and eliminating the possibility of the bag collapsing. Because the vibrating platform is a smooth iron plate, the packaged products are easily removed to the conveyor belt station.
[0016] 2. A lifting cylinder is installed at the bottom of the vibration platform. The function of the lifting cylinder is to raise and lower the platform when needed for work, and to move up and down quickly when the vibration platform is vibrating to participate in the vibration and increase the vibration effect. Attached Figure Description
[0017] Figure 1 This is a schematic diagram of the structure of this utility model;
[0018] Figure 2 This is a structural diagram of a lifting mechanism according to one embodiment of the present utility model. Detailed Implementation
[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with specific embodiments and the appendix, provides further details. Figure 1-2 The present invention will be described in further detail below. It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the present invention.
[0020] This utility model provides a shaking bag device, including a weighing mechanism 1, with a weighing hopper at the upper end of the discharge port of the weighing mechanism. External materials are automatically fed into the weighing hopper, and feeding stops once a set weight is reached, leaving the hopper with the set weight of material. After the lower packaging bag is fitted, a discharge signal is given to the weighing hopper, causing the bottom of the hopper to open, and the set weight of material in the hopper falls through the discharge port into the lower packaging bag.
[0021] The weighing mechanism 1 has a clamping belt mechanism on its discharge port 9. The packaging bag 7 is installed on the discharge port 9 via the clamping belt mechanism. The clamping belt mechanism includes a belt 8 that is fitted onto the discharge port 9. Both ends of the belt 8 are connected to a clamping cylinder 10. The packaging bag 7 is installed between the belt 8 and the discharge port 9. Under the action of the clamping cylinder 10, the belt 8 is tightened or loosened from the discharge port 9. During the weighing process, the clamping belt mechanism first fixes the packaging bag 7 to the discharge port 9, ensuring that the material flows smoothly into the packaging bag 7. When the predetermined weight is reached, the clamping belt mechanism releases, and the packaging bag 7 can be removed. This design ensures the stability of the packaging bag 7 during the weighing process, reduces material loss during filling, and improves weighing accuracy.
[0022] A vibrating platform 6 is located directly below the discharge port 9. The vibrating platform 6 has its sides folded down to ensure smoother movement of the packaging bag 7 and prevent snagging. When material enters the packaging bag 7 through the discharge port 9, the vibrating platform activates, using vibration to help the material flow more smoothly into the packaging bag 7, reducing the accumulation of air and material. The vibrating platform 6 can accelerate the flow of material, reduce material retention at the discharge port 9, and improve filling efficiency.
[0023] The bottom of the vibration platform 6 is equipped with a lifting mechanism. The bottom of the vibration platform 6 is also equipped with a vibration motor 3, which can adjust the vibration frequency and amplitude as needed to adapt to the characteristics of different materials and filling requirements, so as to achieve the best filling effect.
[0024] The lifting mechanism includes guide components located at the four corners of the bottom of the vibration platform 6 and a lifting cylinder 2 located at the center of the vibration platform 6. The top of the lifting cylinder is connected to the vibration platform via a universal floating joint. The guide components include a guide base 4 at the bottom and a guide rod 5 that slides up and down within a sliding groove in the guide base 4. The upper end of the guide rod 5 is connected to the vibration platform 6 via a universal floating joint. When the lifting mechanism is working, the guide rod 5 slides up and down within the sliding groove of the guide base 4, ensuring the vertical movement of the lifting cylinder 2 and preventing inaccurate filling or equipment damage due to offset. Usage: When filling packaging bags of different heights, the operator can adjust the height of the vibration platform by controlling the lifting mechanism to ensure that the packaging bags can be easily placed and removed. The lifting mechanism allows the vibration platform to operate at different heights, adapting to packaging bags of different sizes, improving the flexibility and adaptability of the equipment.
[0025] As the discharge port begins filling the packaging bag, the vibration motor at the bottom of the vibrating platform starts working. Under the action of the vibration motor, the material in the packaging bag is vibrated while being filled, ensuring that the material is firmly packed into the bottom of the packaging bag. To enhance the vibration effect, the cylinder responsible for raising the platform also moves up and down several times during the material filling process. Through this series of actions, the material in the packaging bag is ideally filled into the bag. Once the bagging is complete, the vibration motor stops vibrating, the platform falls, and simultaneously, the clamping mechanism releases the packaging bag. The packaging bag falls with the platform and detaches from the discharge port. The gripping mechanism responsible for transporting the packaging bag picks it up and removes it from the vibrating platform. The next packaging bag is then placed back into the discharge port for the next work cycle. Because of the vertical up-and-down vibration, the packaging bag stands upright on the platform without falling over. At the same time, the empty bag allowance at the top of the packaging bag is increased compared to before, providing stronger support for subsequent sewing.
