A cardboard packaging machine with a feeding structure

Abstract

This utility model provides a cardboard packaging machine with a feeding structure, including a frame. The frame has an internal conveying assembly, which includes two drive rollers rotatably mounted on the inner wall of the frame via two sets of bearings. This cardboard packaging machine with a feeding structure solves the problem of feeding cardboard by using a motor, drive rollers, and a conveyor belt. The conveyor belt can transport cardboard, thus feeding the cardboard. The counterweight and guide rollers work together to ensure the weight of the pressure component is greater than the limit component, ensuring the guide rollers contact the cardboard first and apply pressure to prevent jamming. Furthermore, the connecting pipe and U-shaped plate work together to allow the fixed frame to move upwards and downwards simultaneously. After the top plate moves downwards, it can accurately contact the subsequent cardboard to be conveyed, forming an effective barrier. This achieves precise control of the cardboard feeding rhythm, further optimizing the orderliness and reliability of the overall feeding process.

Description

Technical Field

[0001] This utility model relates to the field of cardboard packaging machine technology, and in particular to a cardboard packaging machine with a feeding structure. Background Technology

[0002] Cardboard is a thick sheet of paper made from pulp, commonly used for packaging and transportation. It comes in various types, such as single-layer cardboard, double-layer cardboard, and corrugated cardboard. Corrugated cardboard is particularly common; its structure consists of two layers of flat paper and a corrugated layer in the middle. This structure makes the cardboard stronger and suitable for making boxes and other packaging materials.

[0003] Referring to patent publication number CN223117416U, a cardboard packaging machine with a feeding structure is disclosed, relating to the field of cardboard packaging machine technology. The machine includes a body, a placement mechanism, and a conveyor belt. The conveyor belt is located at the bottom of the inner side of the machine body, and the placement mechanism is located at the top of the inner side of the machine body. The placement mechanism includes a drive motor, a support roller, and a conveyor belt. This invention, by incorporating an auxiliary feeding mechanism, achieves linkage between the lead screw and the support roller through a bevel gear set and a rotating rod. When the support roller and conveyor belt rotate, the bevel gear set, rotating rod, and lead screw rotate together. Since the lead screw is threadedly connected to a threaded frame, the threaded frame slides horizontally, causing the anti-tipping plate to move synchronously with the conveyor belt. This anti-tipping plate prevents the cardboard-filled packaging bags from tipping over, and, in conjunction with the conveyor belt, provides auxiliary feeding of the cardboard-filled packaging bags, resulting in more stable feeding of the cardboard packaging machine.

[0004] While the above solution can limit the movement of the conveyed cardboard, it still has some shortcomings in actual use. For example, it is not convenient to separate the cardboard during use, which can lead to multiple cardboards entering at the same time when packaging, resulting in the inability to complete the packaging process. Utility Model Content

[0005] This utility model provides a cardboard packaging machine with a feeding structure to solve the technical problem in the above-mentioned background technology that multiple items may enter at the same time, causing the cardboard to be unable to complete the packaging.

[0006] The purpose and effect of this utility model, a cardboard packaging machine with a feeding structure, are achieved by the following specific technical means: A cardboard packaging machine with a feeding structure includes a frame, and a conveying assembly is provided inside the frame. The conveying assembly includes two drive rollers rotatably mounted on the inner wall of the frame via two sets of bearings, and the two drive rollers are connected by a conveyor belt.

[0007] The frame is provided with a pressure assembly for applying pressure to the cardboard. The pressure assembly includes a frame body installed on the upper surface of the frame body, a support rod fixedly installed on the inner wall of the frame body, and a connecting pipe rotatably installed on the outer surface of the support rod through a bearing.

[0008] The frame is provided with a limiting component for blocking the cardboard. The limiting component includes a U-shaped plate installed on the right side of the connecting pipe. The inner wall of the U-shaped plate is rotatably mounted with a connecting rod through two bearings.

[0009] Preferably, a motor is fixedly mounted on the front of the frame, and the output end of the motor is fixedly mounted to the front end of one of the transmission rollers.

[0010] Preferably, a fixing frame is fixedly installed on the outer surface of the connecting pipe, and a counterweight rod is rotatably installed on the inner wall of the fixing frame through two bearings. Two guide wheels are fixedly installed on the outer surface of the counterweight rod.

[0011] Preferably, a perforated connecting sleeve is fixedly installed on the outer surface of the connecting rod, two retaining rings are fixedly installed on the outer surface of the connecting rod, a spring is fixedly installed on the inner top wall of the perforated connecting sleeve, a top plate is fixedly installed on the bottom end of the spring, a concave plate is fixedly installed on the bottom end of the top plate, and two guide rollers are rotatably installed on the inner wall of the concave plate through two sets of bearings.

[0012] Preferably, two support seats are fixedly installed on the bottom surface of the frame, and a guide plate is fixedly installed on the inner wall of the frame.

[0013] Preferably, reinforcing bases are fixedly installed on both the left and right sides of the frame, and the bottom surface of each reinforcing base is fixedly installed to the upper surface of the frame.

[0014] Preferably, an arc-shaped plate is fixedly installed on the outer surface of the fixing frame, and the upper surface of the arc-shaped plate is fixedly installed with the bottom surface of the U-shaped plate.

[0015] Preferably, the front and back of the perforated connecting sleeve are provided with sliding grooves, and a slider is slidably installed on the inner wall of each sliding groove. The sides of the two sliders that are close to each other are fixedly installed to the front and back of the top plate, respectively.

[0016] Beneficial effects:

[0017] 1. By combining a motor, drive rollers, and conveyor belt, the conveyor belt can transport the cardboard, thus feeding the cardboard. The counterweight and guide rollers work together to ensure that the weight of the pressure component is greater than that of the limit component, ensuring that the guide rollers can contact the cardboard first and apply pressure to prevent the cardboard from jamming. Furthermore, by using the connecting pipe and U-shaped plate, the fixed frame can move upward and downward simultaneously. After the top plate moves down, it can accurately contact the cardboard to be conveyed next, forming an effective barrier. This achieves precise control of the cardboard feeding rhythm and further optimizes the orderliness and reliability of the overall feeding process.

[0018] 2. The spring design allows the top plate to block cardboard of different thicknesses, ensuring effective blocking. Furthermore, the combination of the concave plate and guide rollers allows the guide rollers to directly contact the conveyor belt surface instead of the top plate, converting the sliding friction between the two into rolling friction. This not only avoids direct rigid contact between the top plate and the conveyor belt but also reduces friction loss during the conveying process. It effectively prevents the conveyor belt from being damaged or frayed due to scratches and compression, extending the service life of the conveyor belt and reducing equipment maintenance costs.

[0030] A fixing frame 304 is fixedly installed on the outer surface of the connecting pipe 303. A counterweight rod 306 is rotatably installed on the inner wall of the fixing frame 304 through two bearings. Two guide wheels 305 are fixedly installed on the outer surface of the counterweight rod 306. The counterweight rod 306 can increase the weight of the fixing frame 304, ensuring that the guide wheels 305 can contact the cardboard first.

[0031] A perforated connecting sleeve 404 is fixedly installed on the outer surface of the connecting rod 402. Two retaining rings 403 are fixedly installed on the outer surface of the connecting rod 402. A spring 405 is fixedly installed on the inner top wall of the perforated connecting sleeve 404.

The sides of the two sliders 8 that are close to each other are fixedly installed on the front and back sides of the top plate 406, respectively. The top plate 406 can be limited by the sliders 8 and the grooves 7 to prevent the top plate 406 from shaking.

[0036] Working principle: The cardboard is placed on the receiving plate 5 and slides onto the conveyor belt 202. Then, the motor 203 is started, which drives the conveyor belt 202 to rotate through the transmission roller 201. As the conveyor belt 202 rotates, it moves the cardboard. As the cardboard moves to one side of the guide wheel 305, the cardboard pushes the guide wheel 305 upward. Through the cooperation of the fixing frame 304 and the connecting pipe 303, the guide wheel 305 can drive the U-shaped plate 401 downward. The guide wheel 305 allows the cardboard to move smoothly. At the same time, as the U-shaped plate 401 moves downward, the perforated connecting sleeve 404 moves downward. The perforated connecting sleeve 404 and the spring 405 cooperate with the concave plate 407 and the guide roller 408, allowing the guide roller 408 to move downward. The guide roller 408 can then contact the conveyor belt 202 and block the subsequent cardboard.
