Description

Technical Field

[0001] This invention relates to the field of packaging, and in particular to a lifting packaging machine. Background Technology

[0002] As an automated packaging device, the core function of a packaging machine is to precisely seal the contents into bags. In the packaging process, a plastic film is stably fed by a stretching device and then skillfully shaped into a cylindrical structure by rollers. Next, a heat-sealing device seals the sides and ends of the cylindrical film tightly, while the contents are precisely injected into the pre-formed bag.

[0003] In terms of equipment composition, the packaging machine mainly consists of a frame, a hopper mounted on the frame, a lifting device that drives the hopper to rise and fall, and a film feeding device and a heat sealing device also mounted on the frame. In actual operation, the product to be packaged is conveyed into the hopper from the feed inlet. The lifting device raises the hopper to a predetermined height, causing the product to pour into the pre-formed cylindrical plastic film. The subsequent heat sealing device then completes the final sealing process.

[0004] However, the existing equipment design has significant drawbacks. Each lifting operation of the lifting device can only lift and transport one package, a limitation that severely restricts the output efficiency of the packaging machine in a single operation. This not only significantly reduces the overall processing efficiency of the packaging machine but also accelerates equipment wear and tear. To address these problems, this invention has emerged. Summary of the Invention

[0005] The purpose of this invention is to provide a lifting packaging machine that can increase the output efficiency of a single lift, thereby improving the overall processing efficiency of the packaging machine and reducing the operating wear of the equipment.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a lifting packaging machine, including a frame and a lifting device, a film feeding device and a heat sealing device installed on the frame. The lifting device includes a lifting frame that is slidably and vertically arranged on the frame. A storage mechanism is provided in the lifting frame. The storage mechanism includes multiple storage cavities for individually storing packaged items, a feeding component for the packaged items to enter each storage cavity, and multiple discharging components communicating with the storage cavities. The multiple discharging components are arranged in a one-to-one correspondence with the multiple storage cavities. The lifting frame is provided with a control component that cooperates with the discharging components and controls the discharging components to switch between an open state and a closed state.

[0007] By adopting the above technical solution, each package of goods to be packaged is independently filled into the storage chamber by the feeding component for individual storage. After the storage operation of the packaged goods in each storage chamber is completed, the entire storage mechanism is lifted by the lifting frame through the setting of the lifting device. When the lifting frame moves to the upper discharge position, the setting of the control component opens each discharge component in turn, allowing the packaged goods in each storage chamber to fall one by one into the formed cylindrical plastic film, thereby increasing the output efficiency of the equipment per lift. This improves the overall processing efficiency of the packaging machine and reduces the operating wear and tear of the equipment.

[0008] The storage mechanism is further configured such that: the storage mechanism includes a storage bucket having an inner cavity and rotatably mounted on the lifting frame, a fixed limiting bucket installed in the inner cavity of the storage bucket and having a feeding cavity, and a driving component for driving the storage bucket to rotate; the plurality of storage cavities are formed on the outer peripheral wall of the storage bucket and are distributed around the outer peripheral wall of the storage bucket; each of the storage cavities is provided with a docking opening communicating with the inner cavity of the storage bucket; and the fixed limiting bucket restricts the packaging material from passing through the docking opening.

[0009] By adopting the above technical solution, the drive component drives the storage bin to rotate, thereby switching the position of each storage chamber, allowing the items to be packaged to fall into each storage chamber one by one, thus completing the switching operation of the storage chamber.

[0010] The feeding assembly is further configured as follows: the feeding assembly includes a connection port located at the lowest position of the side wall of the fixed limiting barrel, a feeding port located at the end face of the fixed limiting barrel, and a through port located at one end face of the corresponding feeding port of the storage barrel. The orthographic projection path of the connection port intersects the rotation path of the docking opening. When the connection port communicates with one of the docking openings, the docking opening is located below the connection port.

[0011] By adopting the above technical solution, the drive component drives the storage bin to synchronously rotate the docking opening. When the docking opening rotates to the position directly corresponding to the connection port, the storage chamber corresponding to that docking opening is located directly below the connection port. Then, the packaged goods are placed into the feeding chamber through the inlet and outlet. Under the influence of gravity, the packaged goods in the feeding chamber fall into the storage chamber through the connection port and docking opening. The drive component then sequentially switches the storage chambers to be directly below the connection port, thus realizing the feeding operation for each storage chamber. Docking openings without a corresponding connection port position are limited by the fixed limiting bin, allowing the packaged goods to be stably stored in the storage chamber, thereby realizing the loading operation for each storage chamber.

[0012] The discharge assembly is further configured as follows: the discharge port is disposed in the storage tank and communicates with the storage cavity and the outside, a sealing plate is movably disposed in the storage tank and used to open and close the discharge port, and a positioning elastic element is used to position the sealing plate to close the discharge port.

[0013] By adopting the above technical solution, the positioning elastic element positions the sealing plate to close the discharge port, so that the sealing plate is in a closed state when no force is applied, thereby preventing the packaged items from falling into the discharge port.

[0014] The control assembly is further configured as follows: the control unit includes a control seat that reciprocates towards one side of the storage tank, a control cylinder that drives the control seat to move, a control rod disposed on the sealing plate, and a control groove formed in the control seat and cooperating with the control rod.

[0015] By adopting the above technical solution, the control cylinder drives the control seat to move the control groove towards the storage bin. The cooperation between the control groove and the control rod applies force to the sealing plate, causing the positioning elastic element to deform elastically, thus switching the sealing plate from a closed state to an open state, thereby realizing the discharging operation of the packaged goods in the storage chamber. By coordinating the control components with each discharging component, the discharging operation of the packaged goods in each storage chamber can be achieved.

[0016] Further configured as follows: the sealing plate is rotatably mounted on the storage hopper; the process of the sealing plate switching from the closed state to the open state includes a cooperating stroke segment of the cooperating control component and a closing stroke segment to realize the closure of the sealing plate; the control seat has a controlled position and a non-controlled position; when the control seat is in the controlled position, the control rod and the control groove intersect within the cooperating stroke segment.

[0017] By adopting the above technical solution, the control cylinder drives the control seat to switch to the control position, so that part of the movement path of the control rod intersects with the control groove. During the rotation of the storage bin, the control rod rotates synchronously and gradually approaches the control groove, allowing the sealing plate to sequentially pass through the mating stroke section and the closing stroke section. The moving control rod abuts against the control groove, keeping the sealing plate in the mating stroke section. Because the control groove restricts the movement of the sealing plate, while the storage bin continues to move, the opening operation of the discharge port is achieved.

[0018] Because the sealing plate and the storage tank have a rotating structure, the control rod, which is opposed to the controlled groove, gradually moves away from the controlled groove. When it enters the closing stroke section from the mating stroke section, the deflected control rod separates from the controlled groove, and the sealing plate, under the action of the positioning elastic element, achieves automatic closing of the discharge port. This structure is simple and allows for convenient linkage control of each discharge assembly, making the control method more convenient and reducing the failure rate. When the control seat is in the non-control position, the movement paths of the controlled groove and the control rod are staggered, ensuring that the presence of the control components does not affect the normal rotation of the storage tank to complete the switching operation of each storage chamber.

[0019] The lifting device is further configured such that: a plurality of sprockets are rotatably mounted on the frame, a lifting chain is fitted onto the sprockets, and a lifting motor drives one of the sprockets to rotate; the lifting chain is ring-shaped, and the lifting frame is connected to the lifting chain.

[0020] By adopting the above technical solution, the motor drives one of the sprockets to rotate the lifting chain, thereby realizing the lifting and lowering drive operation of the lifting frame.

[0021] The drive assembly is further configured to include a driven gear that rotates with the storage bin, a drive motor mounted on the lifting frame, and a drive gear that is driven by the drive motor and meshes with the driven gear.

[0022] By adopting the above technical solution, the drive motor drives the storage hopper to rotate through the cooperation of the active gear and the driven gear, thereby realizing the driving operation of the storage hopper.

[0023] In summary, the present invention has the following beneficial effects: the present invention can increase the output efficiency of a single lift, thereby improving the overall processing efficiency of the packaging machine and reducing the operating wear and tear of the equipment.
