Description

Technical Field

[0001] This utility model relates to the technical field of packaging box transfer devices, and in particular to a packaging box lid transfer device capable of positioning and correction. Background Technology

[0002] After the lids of the packaging boxes are folded and covered with paper, they are transported to the shelves by a transfer line composed of multiple interconnected conveyor belts, where workers stack them. When the box lids are transported from one conveyor belt to another, the difference in conveyor belt height and the different conveying directions will generate friction in different directions. This will cause the box lids to shift in position after landing on the new conveyor belt. Usually, a correction mechanism needs to be installed on the conveyor belt to restore the box lids to a neat and orderly state on the conveyor belt, so that workers can quickly and neatly stack the formed box lids.

[0003] Patent No. CN202223323707.5 discloses a packaging box printing transmission positioning and correction device. It uses a correction plate mounted on a conveyor belt. The misaligned paper box cover enters the narrow section through the flared opening of the correction plate. The paper box cover is clamped from the left and right sides to correct its position. Rollers are set on the correction plate. The rollers are attached to the side of the paper box cover and move to assist the paper box cover in passing through the correction plate. However, to avoid interference between the rollers during rotation, rollers need to be spaced out so that each roller rotates independently when it comes into contact with the carton lid. This causes the carton lid with a large positional offset to encounter the flared opening. The flared opening's bevel causes the gap between the rollers to face the front of the carton lid. One corner of the carton lid may insert into the gap between the rollers and create resistance, while the other side does not contact the flared opening. In this case, the left and right sides of the carton lid are subjected to uneven force, resulting in an increased deflection angle of the carton lid. Since the rollers in the current technology do not have the ability to actively rotate and push one corner of the carton lid out of the gap, the increased deflection angle of the carton lid can easily block it at the flared opening, hindering the conveying of subsequent carton lids.

[0004] Therefore, designing a packaging box lid transfer device that can actively guide the adjustment of the box lid's position and avoid blockage has become an urgent technical problem to be solved. Summary of the Invention

[0005] To solve the above problems, this utility model provides a packaging box lid transfer device that can position and correct deviations.

[0006] The present invention provides a packaging box lid transfer device capable of positioning and correcting deviations, comprising a first conveyor belt and a second conveyor belt. The tail end of the first conveyor belt is connected to the head end of the second conveyor belt. The second conveyor belt is connected to a deviation correction mechanism, which includes support frames fixed on the left and right sides of the second conveyor belt. The support frames are connected to a pair of deviation correction plates mounted on the second conveyor belt. A deviation correction channel corresponding to the conveying direction of the second conveyor belt is provided between the deviation correction plates. The end of the deviation correction plate is provided with a flared opening. A first motor is connected to the inner side of the flared opening. The first motor shaft is connected to a downwardly extending first drive shaft for linkage. A horizontal turntable is connected to the bottom end of the first drive shaft. Multiple rollers are connected to the bottom surface of the turntable, and the rollers are arranged at intervals along the edge of the turntable.

[0007] With the above structure, by setting the first end of the first conveyor belt at the outlet of the cardboard lid folding and forming device, the first conveyor belt transports the cardboard lid to the tail end, and then the cardboard lid falls onto the second conveyor belt with a different conveying direction for continued transport. As the cardboard lid is transported by the second conveyor belt, it first contacts the flared opening at the end of the correction plate, and moves by using one corner of the cardboard lid against the inner wall of the flared opening to guide the front end of the cardboard lid to align with the correction channel. By activating the first motor on the second conveyor belt, the first motor drives the first drive shaft to rotate, and the first drive shaft drives the turntable to rotate horizontally. The turntable drives the rollers to rotate along a circular trajectory. When one corner of the cardboard lid moves along the flared opening... When the lid reaches the roller, its rotation direction is matched with the conveying direction of the second conveyor belt, pushing the lid towards the aligned correction channel. The lid is then conveyed into the correction channel by the second conveyor belt. Correction plates on both sides of the correction channel limit the lid's position, ensuring it is in a uniform position when leaving the channel. This process involves first guiding a corner of the lid with the inner wall of the flared opening, initially aligning it with the correction channel while approaching the roller. Then, the rotation of the roller further aligns the lid with the correction channel, preventing a corner from getting stuck in the roller gaps and ensuring smooth conveying by the second conveyor belt.

[0008] As a further improvement of this utility model, a second motor matching the number of rollers is fixed on the turntable. The second motor shaft is connected to a downwardly extending second drive shaft for linkage, and the rollers are correspondingly connected to the bottom of the second drive shaft.

[0009] With the above structure, by turning on the second motor, the second motor drives the first drive shaft to rotate. The second drive shaft drives the roller to rotate in a direction that matches the rotation direction, so that the rotation of the roller matches the movement of the carton cover, and further pushes the carton cover to move in the direction of aligning with the correction channel.

[0010] As a further improvement of this utility model, the number of rollers is not less than 3.

[0011] With the above structure, the number of rollers is no less than three, so that when the turntable rotates, the rollers can contact the carton lid at a higher frequency to push it.

[0012] As a further improvement of this utility model, the side of the roller is provided with anti-slip texture.

[0013] With the above structure, the rollers are provided with anti-slip textures on the side, which increases the friction between the rollers and the cardboard box lid, and prevents slippage when the rollers push the cardboard box lid.

[0014] As a further improvement of this utility model, the inner sidewall of the correction plate is axially connected with multiple horizontally rotating rollers, which are arranged laterally along the inner wall of the correction plate.

[0015] With the above structure, multiple horizontally rotating rollers are axially connected to the inner wall of the correction plate. After the carton cover enters the correction channel, the rollers rotate in coordination with the left and right sides of the carton cover, reducing the resistance when the carton cover passes between the correction plates.

[0021] like Figures 1-4The present invention discloses a packaging box lid transfer device capable of positioning and correction, comprising a first conveyor belt 1 and a second conveyor belt 2. The tail end of the first conveyor belt 1 is connected to the head end of the second conveyor belt 2. The second conveyor belt 2 is connected to a correction mechanism, which includes support frames 3 fixed on the left and right sides of the second conveyor belt 2. The support frames 3 are connected to a pair of correction plates 4 mounted on the second conveyor belt 2. A correction channel 5 corresponding to the conveying direction of the second conveyor belt 2 is provided between the correction plates 4. The end is provided with a flared mouth 6. A first motor 7 is connected to the inner side of the flared mouth 6. The first motor 7 is connected to a first drive shaft 8 extending downward for linkage. The bottom end of the first drive shaft 8 is connected to a horizontal turntable 9. Multiple rollers 10 are connected to the bottom surface of the turntable 9. The rollers 10 are arranged at intervals along the edge of the turntable 9.

[0022] Figure 3-4 Arrows I and V indicate the direction of movement of one corner of the carton lid after being pushed by roller 10, and arrows II and III indicate the rotation direction of roller 10. By setting the first end of the first conveyor belt 1 at the outlet of the carton lid folding and forming device, the first conveyor belt 1 transports the carton lid to the end, and then the carton lid falls onto the second conveyor belt 2 with a different conveying direction for continued transport. As the carton lid is transported by the second conveyor belt 2, it first contacts the flared opening 6 at the end of the correction plate 4, and moves by using one corner of the carton lid against the inner wall of the flared opening 6 to guide the front end of the carton lid to align with the correction channel 5. By turning on the second conveyor belt 2, the first motor 7 is activated, which drives the first drive shaft 8 to rotate. The first drive shaft 8 drives the turntable 9 to rotate horizontally, and the turntable 9 drives the roller 10 along a circular trajectory. In the rotation process, when one corner of the cardboard box lid moves along the flared opening 6 to the roller 10, the rotation direction of the roller 10 is matched with the conveying direction of the second conveyor belt 2, pushing the cardboard box lid towards the aligned correction channel 5. Then, the cardboard box lid is conveyed into the correction channel 5 by the second conveyor belt 2. The correction plates 4 on both sides of the correction channel 5 limit the position of the cardboard box lid, so that the cardboard box lid is in a uniform position when leaving the correction channel 5. This achieves the following: first, the inner wall of the flared opening 6 guides the movement of one corner of the cardboard box lid, initially aligning it with the correction channel 5 while approaching the roller 10. Then, the rotation movement of the roller 10 pushes the cardboard box lid further aligned with the correction channel 5, preventing one corner of the cardboard box lid from getting stuck in the gap of the roller 10 and ensuring smooth conveying of the second conveyor belt 2.

[0023] The number of conveyor belts in this technical solution is not limited to two. Users can add a corresponding number of conveyor belts and correction mechanisms. The added conveyor belts are connected end to end according to the assembly method of the first conveyor belt 1 and the second conveyor belt 2. The added correction mechanism is connected to the existing correction mechanism according to the assembly method of the second conveyor belt 2, so as to achieve a more flexible transfer route.

[0024] A second motor 11 is fixed on the turntable 9, matching the number of rollers 10. The second motor 11 is connected to a downwardly extending second drive shaft 12 for linkage. The rollers 10 are correspondingly connected to the bottom of the second drive shaft 12.

[0025] Figure 4 Arrow IV in the diagram indicates the rotation direction of roller 10. By turning on the second motor 11, the second motor 11 drives the second drive shaft 12 to rotate, and the second drive shaft 12 drives roller 10 to rotate in a direction that matches the rotation direction, so that the rotation of roller 10 matches the movement of the carton cover, and further pushes the carton cover to move in the direction of aligning with the correction channel 5.

[0026] The number of rollers 10 shall not be less than 3.

[0027] By using at least three rollers 10, the rollers 10 can contact the carton lid at a higher frequency to push it when the turntable 9 rotates.

[0028] The side of the roller 10 is provided with anti-slip texture 13.

[0029] The roller 10 has anti-slip texture 13 on its side, which increases the friction between the roller 10 and the cardboard box lid, and prevents slippage when the roller 10 pushes the cardboard box lid.

[0030] The inner wall of the straightening plate 4 is axially connected to multiple horizontally rotating rollers 14, which are arranged laterally along the inner wall of the straightening plate 4.

[0031] Multiple horizontally rotating rollers 14 are axially connected to the inner wall of the correction plate 4. After the paper box cover enters the correction channel 5, the rollers 14 rotate in coordination with the left and right sides of the paper box cover to reduce the resistance when the paper box cover passes between the correction plates 4.
