Description

Technical Field

[0001] This utility model relates to the technical field of punching and cutting devices for packaging machines, specifically a composite punching and cutting device for multi-row granule packaging machines. Background Technology

[0002] Existing granule packaging machines are widely used for packaging various granular materials, such as pharmaceuticals, food, and health products. They generally include steps such as metering and feeding, heat sealing, punching, inspection, rejection, and finished product conveying, and have now basically achieved automated processes.

[0003] A search of Chinese patent (publication number: CN221111972U) reveals a punching and cutting device for a food packaging machine, comprising two symmetrical frames, two conveyor belt bodies between the two frames, a common outer shell above the two frames, a push rod mounted on the upper side of the outer shell, a connecting plate at the lower end of the push rod, a cutting blade on the lower side of the connecting plate, symmetrically positioned limiting plates on one side of the connecting plate, a rotating plate rotatably connected between the two limiting plates, a through groove penetrating the outer surface of the rotating plate, and a connecting block slidably connected to the inner wall of the through groove, a punching cutter and a limiting block respectively on the lower and upper sides of the connecting block, a sliding plate slidably connected to the upper side of the rotating plate, an opening on the upper side of the limiting block, a connecting hole corresponding to the position of the opening penetrating the upper side of the sliding plate, and a side of the sliding plate away from the limiting plate. The device has an insertion hole, and a through hole corresponding to the insertion hole is opened on one side of the outer shell. Through a rotating plate and sliding plate, the rotating plate is pulled to rotate outwards, facing the outer shell. Pulling the sliding plate moves the punching tool outwards. Once the punching tool is away from the outer shell, the connection between the sliding plate and the punching tool can be released, allowing the punching tool to be removed. Compared to existing technologies, by moving the punching tool to the outside of the outer shell, it is more convenient to use as the outer shell does not need to be removed when replacing the punching tool. However, during the punching process, the packaging bag is not fixed, and the bag may become skewed due to the force applied, affecting the punching quality. Additionally, the sliding plate, fixed by a sliding rod, may loosen during the punching process. Therefore, a composite punching device for multi-row granule packaging machines is needed to solve these problems. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a composite punching device for multi-row granule packaging machines. It solves the problems of existing devices where the packaging bag is not fixed during the punching process, causing the bag to become skewed and affecting the punching quality. Additionally, the sliding plate, which is fixed by a sliding rod, may become loose during the punching process.

[0005] (II) Technical Solution The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A composite punching device for a multi-row granule packaging machine includes a support frame, two sets of conveyor belts are provided on the support frame, a bearing plate is provided between the two sets of conveyor belts, a fixed frame is installed on the top of the support frame, a hydraulic cylinder is installed on the top of the fixed frame, a cross frame is provided inside the fixed frame, a cutting tool and a punching tool are respectively provided at the bottom of the cross frame, a stabilizing mechanism is provided at the bottom of the cross frame, and a fixing mechanism is provided at the bottom of the cross frame and around the punching tool.

[0006] Preferably, the stabilizing mechanism includes multiple sets of sleeves installed at the bottom of the cross frame. Each set of sleeves is threaded with an installation head. Each set of installation heads is movably connected to a telescopic rod. One end of each set of telescopic rods, located inside the sleeve, is installed with an end plate. Each set of sleeves is provided with a spring. One end of the multiple sets of telescopic rods is jointly installed with a stabilizing frame.

[0007] Preferably, each of the sleeves has a threaded hole at its port that is compatible with the mounting head.

[0008] Preferably, each mounting head is provided with a through hole that is compatible with the telescopic rod.

[0009] Preferably, the fixing mechanism includes a limiting frame installed at the bottom of the crossbeam. Two sets of moving blocks are provided inside the limiting frame. Each set of moving blocks has a threaded rod installed on its surface. Each set of threaded rods has a nut threaded on its surface. Semicircular retaining rings are installed at the bottom of both sets of moving blocks. Two sets of locking plates are symmetrically installed on the surface of each set of semicircular retaining rings. Fastening bolts are threaded into the locking plates on the same side.

[0010] Preferably, each of the limiting frames is provided with a rectangular adjustment groove adapted to the moving block, and the side of the limiting frame is provided with a sliding groove adapted to the threaded rod. The moving block and the limiting frame are fixed together by the threaded rod and the nut.

[0012] The beneficial effects of this utility model are: 1) The composite punching device for multi-row granule packaging machine transmits the packaging bag to the area below the cutting and punching tools via a portion of the conveyor belt. Then, the horizontal frame is driven to descend by the hydraulic cylinder, which in turn drives the pressure stabilizing frame to contact the packaging bag and fix it. After the packaging bag is fixed, the horizontal frame continues to move downward and punches it using the cutting and punching tools, effectively ensuring the punching quality of the device.

[0013] 2) When the composite punching device used in the multi-row granule packaging machine needs to replace the punching tool, simply loosen the nut and tighten the bolt, then replace the punching tool. After replacement, place the new punching tool between the two sets of semi-circular retaining rings, then move the semi-circular retaining rings to make them fit tightly against the surface of the punching tool, and finally fix it with the nut and tightening bolt. This ensures the stability of the punching tool and facilitates replacement. Attached Figure Description
