Description

Technical Field

[0001] This application relates to the technical field of packaging machines, and in particular to a lower mold structure for a packaging machine. Background Technology

[0002] With the development of the times, the demand for packaging machines is getting higher and higher.

[0003] A packaging machine in the related art includes a frame, on which a lower mold mechanism is provided.

[0004] After the lower mold mechanism is installed on the frame, workers need to use tools and bolts to lock the lower mold mechanism to the frame, which increases the assembly time of the lower mold mechanism and needs to be improved. Summary of the Invention

[0005] To reduce the installation time of the lower mold mechanism, this application provides a lower mold structure for a packaging machine.

[0006] The lower mold structure of a packaging machine provided in this application adopts the following technical solution: A lower mold structure for a packaging machine includes a frame, a lower mold mechanism mounted on the frame, and a first locking mechanism for locking the lower mold mechanism. The first locking mechanism includes a locking plate mounted on the frame, a storage slot on the upper surface of the locking plate, a locking post disposed in the storage slot, a mounting frame mounted on the frame, and a lower mold template slidably mounted on the mounting frame. A lower mold base is mounted above the lower mold template, and a locking slot for inserting the locking post is provided on the lower surface of the lower mold template. The first locking mechanism further includes a lifting assembly for driving the locking plate to rise and fall.

[0007] By adopting the above technical solution, the lower mold mechanism is installed on the frame. The lifting component drives the locking plate and locking column to rise, so that the locking column is inserted into the locking groove to lock the lower mold plate, thereby locking the lower mold mechanism to the frame. Conversely, the lifting component drives the locking column to disengage from the locking groove, releasing the lock on the lower mold mechanism, which makes it easier for workers to replace the lower mold mechanism. This enables quick disassembly and assembly of the lower mold mechanism and saves the time required for locking the lower mold mechanism.

[0008] Optionally, a stop block is provided on the lower end face of the lower template, and the locking post is located on the path along which the stop block moves in the width direction of the frame.

[0009] By adopting the above technical solution, when the stop block abuts against the locking post during the horizontal movement of the lower mold mechanism, the lower mold mechanism is restricted from continuing to move, thus playing a limiting role. At this time, the locking groove is aligned with the locking post, making it easier for the locking post to rise and insert into the locking groove.

[0010] Optionally, a roller is rotatably connected to the lower part of the lower template, and the roller can contact the upper surface of the mounting frame.

[0011] By adopting the above technical solution, the use of rollers to move the lower mold mechanism reduces wear on the lower mold compared to the method of the lower mold plate sliding directly with the mounting frame, while also saving effort.

[0012] Optionally, the lifting assembly includes a support frame disposed below the frame, a lifting plate disposed below the support frame, a second connecting rod rotatably connected to the lifting plate, a first connecting rod rotatably connected to the support frame, the first connecting rod and the second connecting rod being hinged, a support block disposed on the side of the support frame, a top rod passing through the support block, the lower end of the top rod being connected to the lifting plate, the upper end of the top rod being connected to a locking plate, and a rotary drive source capable of driving the first connecting rod to rotate disposed on the support frame.

[0013] By adopting the above technical solution, the rotary drive source drives the first connecting rod to rotate, and the first connecting rod drives the second connecting rod, the lifting plate and the ejector rod to move and rise together. The ejector rod drives the locking plate and the locking pin to rise, so that the locking pin is inserted into the locking groove and locks the lower mold mechanism. After the locking pin has locked the locking plate, the rotary drive source continues to drive the lifting plate and the ejector rod to rise, which can realize the lower mold mechanism rising and enable the lower mold mechanism to perform the mold closing action with the upper mold mechanism. Conversely, the rotary drive source drives the lifting plate and the ejector rod to fall, so that the upper mold mechanism and the lower mold mechanism perform the mold opening action.

[0014] Optionally, the upper end face of the top rod is provided with an inflation groove, the outer circumferential surface of the top rod is provided with an inflation hole communicating with the inflation groove, the lower end face of the lower template is provided with a through hole communicating with the inflation groove, and the lower end face of the lower mold base is provided with an inflation channel communicating with the through hole.

[0015] By adopting the above technical solution, the rotary drive source drives the first connecting rod to rotate, the first connecting rod drives the second connecting rod and the lifting plate to rise, the lifting plate drives the top rod to rise, so that the top rod abuts against the lower template, and the mounting groove connects with the through hole. Air can be injected into the lower mold base through the air hole, air groove, through hole and air channel.

[0016] Optionally, the frame is provided with a second locking mechanism for locking the lower mold mechanism. The second locking mechanism includes a lifting cylinder mounted on a support frame. The lifting cylinder includes a slider that can be raised and lowered. A locking rod is provided on the upper end face of the slider. A locking hole is opened on the lower end face of the lower mold plate. The upper end of the locking rod passes through the frame and the locking plate. The upper end of the locking rod can be inserted into the locking hole.

[0017] By adopting the above technical solution, the lifting cylinder drives the slide bar and locking bar to rise, so that the locking bar is inserted into the locking hole, thereby locking the lower mold plate and making it difficult for the lower mold mechanism to move horizontally.

[0018] Optionally, the lower mold base has a lower mold cavity, the lower mold cavity is provided with a material support component, the lower inner wall of the lower mold cavity has an insertion hole that can communicate with the locking hole, and the locking rod can abut against the lower part of the material support component.

[0019] By adopting the above technical solution, the material support component can support the tray, and the lifting and lowering of the locking rod can drive the material support component to rise and fall, so that the tray comes into contact with the packaging film, which facilitates the packaging mechanism to heat seal the tray and the packaging film; conversely, the lifting cylinder can drive the locking rod and the material support component to fall.

[0020] Optionally, a handle is provided on the side of the lower mold base.

[0021] By adopting the above technical solution, the handle facilitates the horizontal movement of the lower mold mechanism by the staff.

[0022] Optionally, the lifting plate is provided with a vacuum connector, the upper end of the vacuum connector is provided with a vacuum tube, the lower end face of the locking plate is provided with an operating hole for inserting the vacuum tube, the lower end face of the lower mold base is provided with a vacuum channel communicating with the lower mold cavity, and the lower end face of the lower template is provided with a vent hole communicating with the vacuum channel; when the locking plate abuts against the lower template, the vent hole can communicate with the operating hole.

[0023] By adopting the above technology, when the lifting assembly drives the lifting plate, vacuum connector, vacuum tube and locking plate to rise together, and the locking plate abuts against the lower template, the operating hole and the vent hole are connected, so that the vacuum equipment can perform a vacuuming action on the lower template mechanism through the vacuum connector, vacuum tube, operating hole, vent hole and vacuum channel.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. Install the lower mold mechanism onto the frame. The lifting assembly drives the locking plate and locking column to rise, so that the locking column is inserted into the locking groove to lock the lower mold plate, thereby locking the lower mold mechanism to the frame. Conversely, the lifting assembly drives the locking column to disengage from the locking groove, releasing the lock on the lower mold mechanism, making it easier for workers to replace the lower mold mechanism. This enables quick disassembly and assembly of the lower mold mechanism and saves the time required for locking the lower mold mechanism. 2. Using the ejector rod for the inflation process and the vacuum tube for the evacuation process simplifies the upper mold mechanism of the packaging machine. Attached Figure Description
