Description

Technical Field

[0001] This utility model relates to the field of corrugated paper packaging box production technology, and in particular to a sealing device for corrugated paper packaging box production. Background Technology

[0002] The corrugated cardboard box production sealing device is an automated equipment used in the manufacturing process of corrugated cardboard boxes to complete the sealing and fastening of the boxes. The device mainly uses mechanical or automated technology to seal the bottom or top of the boxes to ensure that the boxes maintain structural stability during transportation and storage, and to prevent them from falling apart or deforming.

[0003] When using a sealing machine to seal corrugated cardboard boxes, the boxes are placed on one side of the machine, folded in half at the seam, and pushed onto several conveyor rods. The internal drive motor rotates the chain and sprockets, which in turn rotates the conveyor rods, transporting the folded boxes. Once a certain position is reached, the internal electric telescopic rod moves the carriage and sealer downwards, sealing the seam of the corrugated box on the sealing frame. Because the folded boxes are prone to shaking and shifting during transport on the conveyor rods, they may shift or tilt when they reach the sealer. This shift can prevent the sealer from accurately aligning with the box seam, affecting the sealing effect. This can lead to weak or incomplete sealing, production line stagnation, or quality problems, ultimately reducing production efficiency and packaging quality. Utility Model Content

[0004] The technical problem this utility model aims to solve is that the folded packaging box is prone to shaking and shifting during the conveyor rod process, which causes the carton to shift or tilt when it is conveyed to the bottom of the sealing device. This shift will prevent the sealing device from accurately aligning with the packaging box interface, thereby affecting the sealing effect. It may result in an insecure seal, incomplete sealing, or even production line stagnation or quality problems, thereby reducing production efficiency and packaging quality.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a sealing device for corrugated cardboard packaging boxes, including a sealing machine. A slide is slidably installed on the inner wall of the sealing machine, and a sealing device is provided on one side of the slide. Several conveying rods are rotatably installed on the inner wall of the sealing machine, and a sealing frame is provided on one side of the sealing machine. A limiting device is provided on the inner wall of the sealing machine. The limiting device can slide its two limiting frames on the conveying rods to a certain position according to the size of the corrugated cardboard packaging box to be sealed, and then fix them by a fixing mechanism to limit and block the two sides of the corrugated cardboard packaging box to be sealed, thereby preventing deviation and shaking during the conveying process and improving the sealing effect and efficiency.

[0006] Preferably, the limiting device includes a rotating rod, one end of which is rotatably mounted on one side of the inner wall of the sealing machine; two connecting rods, one end of which is rotatably mounted on one side of the rotating rod; two limiting frames, one end of which is sleeved on the outer surface of several conveying rods, and one side is rotatably connected to one end of the connecting rod, a limiting telescopic rod is fixedly mounted on one side of the limiting frame, and one end of the limiting telescopic rod is fixedly mounted on one side of the inner wall of the sealing machine; and a fixing mechanism, wherein the fixing mechanism is disposed between one side of the limiting frame and the inner wall of the sealing machine, for fixing and locking the limiting frame whose position is adjusted.

[0007] The aforementioned components achieve the following effect: When using a sealing machine to seal corrugated cardboard boxes, one of the limiting frames can be manually pulled to a certain position on the conveyor rod according to the size of the box to be sealed. This causes the limiting telescopic rod to stretch, and the bottom rotating connecting rod to rotate, pushing the rotating rod to rotate within the sealing machine's inner wall. This, in turn, pushes another connecting rod, causing the other limiting frame to move in the opposite direction, thus adjusting the distance between the two limiting frames. After adjustment, the fixing mechanism secures and locks the box in place. During the sealing process, the corrugated cardboard box can be placed on one side of the sealing machine, and its seam folded over before sealing. The corrugated cardboard boxes are placed on the frame and pushed onto several conveyor rods on the sealing machine, positioned between two limit frames. This effectively ensures that the corrugated cardboard boxes do not shake or shift during transport, maintaining an accurate position when the boxes are fed into the sealing device. This improves sealing accuracy and avoids insecure or incomplete sealing due to offset or tilting, thereby increasing production efficiency and packaging quality. Then, the drive motor inside the sealing machine is started, which drives the chain and sprocket to rotate, thereby driving several conveyor rods to rotate and convey the folded corrugated cardboard boxes. When the boxes are conveyed to a certain position, the electric telescopic rod inside the sealing machine is activated, which drives the slide and the sealing device to move downwards, sealing the joints of the corrugated cardboard boxes on the sealing frame.

[0008] Preferably, a plurality of circular rollers are rotatably mounted on one side of the limiting frame, wherein the plurality of circular rollers are arranged at equal intervals.

[0009] The effect achieved by the above components is that by setting up the circular roller, the contact wear between the limiting frame and the folded corrugated cardboard packaging box to be conveyed can be reduced, the resistance can be reduced, and the limiting frame can limit the conveying operation without hindering the conveying operation.

[0010] Preferably, a reinforcing rod is symmetrically fixedly installed on the outer surface of one end of the limiting telescopic rod, and one side of the reinforcing rod is fixedly installed on one side of the limiting frame.

[0011] The effect achieved by the above components is that by setting up reinforcing rods, the connection area between the limiting telescopic rod and the limiting frame can be increased, making the connection more solid and stable, and less prone to breakage and damage.

[0012] Preferably, a limiting plate is fixedly installed on one side of the limiting frame, and the limiting plate is fixedly installed on one side of the limiting frame at an angle.

[0013] The effect achieved by the above components is that by setting a limiting plate, the area at the entrance between the two limiting frames can be increased, making it easier to push the folded corrugated cardboard box between the two limiting frames and improving the sealing and sealing efficiency.

[0014] Preferably, the fixing mechanism includes a rectangular rod, both sides of which are fixedly installed on the inner walls of the sealing machine, and a plurality of locking holes are provided on one side of the rectangular rod; two locking blocks, wherein the locking blocks are slidably installed in the inner wall of one end of the limiting frame, and one end is inserted into the inner wall of the locking hole; and two springs, wherein the two ends of the springs are respectively fixedly installed on one side of the locking block and one side of the inner wall of the limiting frame.

[0015] The effect achieved by the above components is as follows: by setting a fixing mechanism, when adjusting the limiting frame, the locking block can slide to one end to a certain position in the inner wall of the limiting frame, causing the spring to contract, and then the limiting frame can be adjusted. After adjustment, the locking block can be released, and under the reset action of the spring, it can be locked into the corresponding locking hole on the rectangular rod, thereby fixing and locking the adjusted limiting frame on the rectangular rod, so as to limit and block the corrugated cardboard packaging box.

[0016] Preferably, the fixing mechanism further includes two supporting telescopic rods, wherein the outer surface of the supporting telescopic rods is inserted into the inner wall of the spring, and both ends are respectively fixedly installed on one side of the locking block and one side of the inner wall of the limiting frame.

[0017] The effect achieved by the above components is as follows: by setting up the support telescopic rod, the inner wall of the spring can be supported and reinforced, making it less prone to damage during use. At the same time, the locking block is limited, making it less prone to shaking during use.

[0018] The beneficial effects of this utility model are:

[0019] When using a sealing machine to seal corrugated cardboard boxes, you can manually pull one of the limiting frames along the conveyor rod to a certain position according to the size of the box. This stretches the limiting telescopic rod, causing the bottom rotating connecting rod to rotate and push the rotating rod to rotate inside the sealing machine. This then pushes another connecting rod, moving the other limiting frame in the opposite direction. This adjusts the distance between the two limiting frames. After adjustment, the fixing mechanism secures and locks the box in place. During sealing, the corrugated cardboard box can be placed on one side of the sealing machine, its seam folded over onto the sealing frame, and then pushed into the sealing position. The machine has several conveyor rods positioned between two limit frames. This effectively ensures that the corrugated cardboard boxes do not shake or shift during transport, maintaining an accurate position when the boxes are fed into the sealing device. This improves sealing accuracy and prevents loose or incomplete sealing due to offset or tilting, thereby increasing production efficiency and packaging quality. Then, the drive motor inside the sealing machine is activated to rotate the chain and sprocket, which in turn rotates the several conveyor rods to transport the folded corrugated cardboard boxes. Once the boxes have reached a certain position, the electric telescopic rod inside the sealing machine is activated to move the slide and sealing device downwards, sealing the joints of the corrugated cardboard boxes on the sealing frame.

[0028] Figure 1-4 The corrugated cardboard packaging box production and sealing device shown includes a sealing machine 1. A slide 3 is slidably installed on the inner wall of the sealing machine 1. A sealing device 4 is provided on one side of the slide 3. Several conveying rods 5 are rotatably installed on the inner wall of the sealing machine 1. A sealing frame 6 is provided on one side of the sealing machine 1. A limiting device 2 is provided on the inner wall of the sealing machine 1. The limiting device 2 can slide its two limiting frames 23 on the conveying rods 5 to a certain position according to the size of the corrugated cardboard packaging box to be sealed, and then fix them by the fixing mechanism 25. This limits and blocks the two sides of the corrugated cardboard packaging box to be sealed, thereby preventing deviation and shaking during the conveying process and improving the sealing effect and efficiency.

[0029] Figure 1-4The limiting device 2 shown includes a rotating rod 21, one end of which is rotatably mounted on one side of the inner wall of the sealing machine 1; two connecting rods 22, one end of which is rotatably mounted on one side of the rotating rod 21; two limiting frames 23, one end of which is sleeved on the outer surface of several conveying rods 5, and one side is rotatably connected to one end of the connecting rod 22; a limiting telescopic rod 24 is fixedly mounted on one side of the limiting frame 23, one end of which is fixedly mounted on one side of the inner wall of the sealing machine 1; and a fixing mechanism 25, which is disposed between one side of the limiting frame 23 and the inner wall of the sealing machine 1, for fixing and locking the limiting frame 23 whose position is adjusted. When using the sealing machine 1 to seal corrugated cardboard boxes, one of the limiting frames 23 can be manually pulled to a certain position on the conveyor rod 5 according to the size of the corrugated cardboard box to be sealed. This causes the limiting telescopic rod 24 to stretch, and the bottom rotating connecting rod 22 will rotate, pushing the rotating rod 21 to rotate in the inner wall of the sealing machine 1. This pushes the other connecting rod 22 to move, causing the other limiting frame 23 to move in the opposite direction, thereby adjusting the distance between the two limiting frames 23. After adjustment, the fixing mechanism 25 is used to fix and lock the box. In this way, during the sealing process, the corrugated cardboard box can be placed on one side of the sealing machine 1, and its joint can be folded in half on the sealing frame 6. The corrugated cardboard boxes are pushed onto several conveyor rods 5 on the sealing machine 1 and positioned between two limit frames 23. This effectively ensures that the corrugated cardboard boxes do not shake or shift during the conveying process, so that the boxes maintain an accurate position when they are fed into the sealing device 4, improving the sealing accuracy and avoiding loose or incomplete sealing due to offset or tilt. This, in turn, improves production efficiency and packaging quality. Then, the drive motor inside the sealing machine 1 is started to drive the chain and sprocket to rotate, which in turn drives several conveyor rods 5 to rotate and convey the folded corrugated cardboard boxes. When the boxes are conveyed to a certain position, the electric telescopic rod inside the sealing machine 1 is started to drive the slide 3 and the sealing device 4 to move downwards and seal the interface of the corrugated cardboard boxes on the sealing frame 6.

[0030] Figure 1-4 A plurality of circular rollers 26 are rotatably mounted on one side of the limiting frame 23 shown, wherein the circular rollers 26 are arranged at equal intervals. By setting the circular rollers 26, the contact wear between the limiting frame 23 and the folded corrugated cardboard packaging box to be conveyed can be reduced, the resistance can be reduced, and the limiting frame 23 can limit the corrugated cardboard packaging box without hindering the conveying operation.

[0031] Figure 1-4A reinforcing rod 27 is symmetrically fixedly installed on the outer surface of one end of the limiting telescopic rod 24, and one side of the reinforcing rod 27 is fixedly installed on one side of the limiting frame 23. By setting the reinforcing rod 27, the connection area between the limiting telescopic rod 24 and the limiting frame 23 can be increased, making the connection more secure and stable, and less prone to breakage or damage. A limiting plate 28 is fixedly installed on one side of the limiting frame 23, and the limiting plate 28 is fixedly installed at an angle on one side of the limiting frame 23. By setting the limiting plate 28, the area of ​​the entrance between the two limiting frames 23 can be increased, making it easier to push the folded corrugated cardboard box between the two limiting frames 23, thereby improving the sealing processing efficiency.

[0032] Figure 1-4 The fixing mechanism 25 shown includes a rectangular rod 251, both sides of which are fixedly installed on the inner wall of the sealing machine 1. A plurality of locking holes 252 are provided on one side of the rectangular rod 251; two locking blocks 253, wherein the locking blocks 253 are slidably installed in the inner wall of one end of the limiting frame 23, and one end is inserted into the inner wall of the locking hole 252; and two springs 254, wherein the two ends of the springs 254 are respectively fixedly installed on one side of the locking block 253 and one side of the inner wall of the limiting frame 23. By setting the fixing mechanism 25, when adjusting the limiting frame 23, the locking block 253 can slide to one end in a certain position within the inner wall of the limiting frame 23, causing the spring 254 to contract. Then, the limiting frame 23 is adjusted. After adjustment, the locking block 253 can be released, allowing it to engage with the corresponding locking hole 252 on the rectangular rod 251 under the reset action of the spring 254. This fixes and locks the adjusted limiting frame 23 onto the rectangular rod 251, enabling it to limit and block the corrugated cardboard packaging box. The fixing mechanism 25 also includes two supporting telescopic rods 255. The outer surface of the supporting telescopic rods 255 is inserted into the inner wall of the spring 254, and both ends are fixedly installed on one side of the locking block 253 and one side of the inner wall of the limiting frame 23, respectively. By setting the supporting telescopic rods 255, the inner wall of the spring 254 can be supported and reinforced, making it less prone to damage during use. It also limits the locking block 253, preventing it from shaking during use.

[0033] Working Principle: When using the sealing machine 1 to seal corrugated cardboard boxes, the size of the corrugated cardboard box to be sealed can be determined by first sliding the locking block 253 to one end in a certain position within the inner wall of the limiting frame 23, causing the spring 254 to contract. Then, one of the limiting frames 23 is manually pulled to one end on the conveyor rod 5 to a certain position, causing the limiting telescopic rod 24 to extend. Simultaneously, the bottom rotating connecting rod 22 rotates, pushing the rotating rod 21 to rotate within the inner wall of the sealing machine 1, which in turn pushes the other connecting rod 22 to move, causing the other limiting frame 23 to move in the opposite direction. This adjusts the distance between the two limiting frames 23. Finally, after adjustment, the locking block 253 can be released, allowing it to engage with the corresponding locking hole 252 on the rectangular rod 251 under the reset action of the spring 254, thus fixing and locking the adjusted limiting frame 23 within the rectangular rod. On rod 251, during the sealing process, the corrugated cardboard box can be placed on one side of the sealing machine 1, then its joint is folded over onto the sealing frame 6 and pushed onto several conveyor rods 5 on the sealing machine 1, positioned between two limit frames 23. This effectively ensures that the corrugated cardboard box is not prone to shaking or shifting during transport, keeping the box in an accurate position when fed into the sealer 4, improving sealing accuracy, and avoiding insecure or incomplete sealing due to offset or tilt, thereby improving production efficiency and packaging quality. Then, the drive motor inside the sealing machine 1 is started to drive the chain and sprocket to rotate, which in turn drives several conveyor rods 5 to rotate, conveying the folded corrugated cardboard box. When it is conveyed to a certain position, the electric telescopic rod inside the sealing machine 1 is started to drive the slide 3 and the sealer 4 to move downwards, sealing the joint of the corrugated cardboard box on the sealing frame 6.
