Description

Technical Field

[0001] This utility model relates to the field of cardboard box production technology, and in particular to a cardboard box conveying device for continuous printing. Background Technology

[0002] In traditional carton conveying, ordinary belt conveyors are commonly used, relying on a motor-driven belt rotation to move the cartons. However, in practical applications, this method is prone to belt slack after prolonged operation, causing cartons to slip or shift during transport, affecting printing quality and subsequent processes. Furthermore, ordinary belt conveyors lack effective support structures, and when conveying heavy cartons, the belt is prone to excessive deformation, further compromising transport stability.

[0003] Traditional methods for counting cartons mainly rely on manual counting or simple electronic sensors. Manual counting is not only inefficient, but also prone to errors after prolonged use, making it unsuitable for large-scale continuous production. Utility Model Content

[0004] The purpose of this invention is to provide a continuous printing carton conveying device that solves the problems of unstable carton conveying, slippage and deviation, and low efficiency of manual counting in traditional methods.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A continuous printing carton conveying device includes a conveying assembly. A bracket is fixedly connected to the top of the conveying assembly. A slide rod is symmetrically slidably connected inside the bracket. A guide plate is fixedly connected to the bottom end of the slide rod. A rotating frame is symmetrically fixedly connected to the top of the bracket. A first ratchet and a second ratchet are rotatably connected to the outside of the rotating frame. A counting wheel is fixedly connected to one side of the first ratchet and one side of the second ratchet. A swing arm is rotatably connected to the outside of the rotating frame. A groove is provided on one side of the swing arm. A linkage rod is fixedly connected to one side of the slide rod. One end of the linkage rod is slidably connected inside the groove. A short rod is rotatably connected inside the top of the swing arm. A first pawl and a second pawl are fixedly connected to the outside of the short rod. The first pawl and the second pawl respectively cooperate with the first ratchet and the second ratchet. A groove is provided on the surface of the first ratchet.

[0006] Preferably, the conveying assembly includes a conveying frame, a drive shaft, a driven shaft, pulleys, and a motor. The drive shaft and the driven shaft are rotatably connected to both sides of the conveying frame via bearings. Pulleys are fixedly connected at equal intervals to the outer sides of both the drive shaft and the driven shaft. The corresponding pulleys on the outer sides of the drive shaft and the driven shaft are connected by belt drive. A bracket is fixedly connected to the top of the conveying frame. A motor is fixedly installed on one side of the conveying frame. The output shaft of the motor is fixedly connected to the corresponding end of the drive shaft.

[0007] Preferably, the top and bottom of the conveyor frame are fixedly connected with several support plates at equal intervals, and the support plates at the top and bottom are set one-to-one. The belt is wrapped around the outside of the two support plates at the top and bottom respectively, and the support plates provide rigid support to the belt to avoid excessive deformation due to the weight of the carton board and ensure the smooth conveying of the carton board.

[0008] Preferably, the two ends of the support plate are curved, which can guide the belt to transition smoothly, reduce local compression deformation and edge wear, and extend the belt's service life.

[0009] Preferably, sleeves are symmetrically fixed inside the bracket, and the slide rods are slidably connected inside the corresponding sleeves. The sleeves provide a stable sliding track for the slide rods, making the slide rods slide more smoothly.

[0010] Preferably, the guide plate is curved upwards in an arc shape facing the side opposite to the conveying direction of the conveying component. When the carton passes by, it slides along the arc surface and pushes the guide plate upwards, thereby triggering the subsequent counting action.

[0011] Preferably, the guide plate has rounded corners at all four corners to prevent scratching and damaging the cardboard, reduce production losses, and improve product quality.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] This invention achieves accurate counting of cardboard boxes by incorporating components such as a guide plate, slide bar, swing arm, and ratchet pawl. When a cardboard box passes the guide plate, it moves the guide plate and slide bar up and down, which in turn drives the swing arm to swing. This causes the first pawl to push the first ratchet to rotate one tooth, completing the units digit count. When the first ratchet rotates to a specific position, the second pawl pushes the second ratchet to rotate one tooth, completing the tens digit count. This design ensures the accuracy and reliability of the counting, providing precise data support for production statistics.

[0014] This invention provides a stable support path for the belt by using support plates equidistantly arranged at the top and bottom of the conveyor frame. The top support plate is located below the upper conveying section of the belt, and the bottom support plate is located above the lower return section of the belt. This ensures that the belt maintains a horizontal tension during operation, preventing slippage or deviation due to belt slack. At the same time, the support plates provide rigid support for the belt, preventing excessive deformation due to the weight of the cardboard and ensuring smooth transport of the cardboard. In addition, the curved ends of the support plates guide the belt through a smooth transition, avoiding local compression deformation or edge wear caused by right-angle edges, extending the belt's service life and reducing equipment maintenance costs.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1 to 4 This embodiment provides a continuous printing carton conveying device, including a conveying assembly 1. A bracket 2 is fixedly connected to the top of the conveying assembly 1. A slide rod 4 is symmetrically slidably connected inside the bracket 2. A guide plate 5 is fixedly connected to the bottom end of the slide rod 4. The guide plate 5 is curved upwards in an arc shape towards the side opposite to the conveying direction of the conveying assembly 1. A rotating rod frame 6 is symmetrically fixedly connected to the top of the bracket 2. A first ratchet 7 and a second ratchet 8 are rotatably connected to the outside of the rotating rod frame 6. A counting wheel 9 is fixedly connected to one side of the first ratchet 7 and one side of the second ratchet 8. A swing arm 10 is rotatably connected to the outside of the rotating rod frame 6. A groove 11 is provided on one side of the swing arm 10. A linkage rod 12 is fixedly connected to one side of the slide rod 4. One end of the linkage rod 12 is slidably connected inside the groove 11. A short rod 13 is rotatably connected inside the top end of the swing arm 10. A first pawl 14 and a second pawl 15 are fixedly connected to the outside of the short rod 13. The first pawl 14 and the second pawl 15 cooperate with the first ratchet 7 and the second ratchet 8, respectively. A groove 16 is provided on the surface of the first ratchet 7.

[0022] When the carton is conveyed on the conveying assembly 1, it will pass under the guide plate 5 in sequence. Since the guide plate 5 is curved and upturned in an arc shape to the side opposite to the conveying direction, the carton will slide along the arc surface of the guide plate 5 when it passes by, and push the guide plate 5 upward. The guide plate 5 moves upward and drives the slide rod 4 to slide upward in the sleeve 3. When the slide rod 4 slides upward, the linkage rod 12 fixed on one side of the slide rod 4 slides in the slide groove 11 of the swing arm 10, thereby driving the swing arm 10 to swing around its fixed point. When the swing arm 10 swings, it drives the first pawl 14 and the second pawl 15 to move synchronously through the short rod 13. Since the first pawl 14 cooperates with the first ratchet 7, the first pawl 14 will push the first ratchet 7 to rotate one tooth position.

[0023] After the cardboard passes the guide plate 5, the guide plate 5 descends under the action of gravity, causing the slide bar 4 to slide downwards. The linkage rod 12 drives the swing arm 10 to reset. Since the angle of the second pawl 15 is slightly higher than that of the first pawl 14, during the reset process of the swing arm 10, when the first pawl 14 is engaged with the first ratchet 7, the second pawl 15 is not engaged with the second ratchet 8. Only when the first ratchet 7 rotates to the groove 16 directly facing the first pawl 14 can the first pawl 14 enter the groove 16 and rotate an excessive angle. At this time, the second pawl 15 will engage with the second ratchet 8 and push it to rotate one tooth position. Therefore, for every rotation of the first ratchet 7, the counting wheel 9 completes the units digit count, and the second ratchet 8 rotates one tooth position, and the counting wheel 9 completes the tens digit count.

[0024] To extend the counting to hundreds, a third ratchet and a third pawl can be added, and a groove 16 can be added to the surface of the second ratchet 8 so that the angle of the newly added third pawl is higher than that of the second pawl 15. When the second ratchet 8 rotates until its groove 16 is directly opposite the second pawl 15, the third pawl can engage with the third ratchet, thus enabling hundreds counting. This can be repeated to extend the counting to even higher digits.

[0025] The conveying assembly 1 includes a conveying frame 101, a drive shaft 102, a driven shaft 103, pulleys 104, and a motor 105. The drive shaft 102 and the driven shaft 103 are rotatably connected to both sides of the conveying frame 101 via bearings. Pulleys 104 are fixedly connected at equal intervals to the outer sides of the drive shaft 102 and the driven shaft 103. The corresponding pulleys 104 on the outer sides of the drive shaft 102 and the driven shaft 103 are connected by belt drive. The bracket 2 is fixedly connected to the top of the conveying frame 101. The motor 105 is fixedly installed on one side of the conveying frame 101. The output shaft of the motor 105 is fixedly connected to the corresponding end of the drive shaft 102.

[0026] After the motor 105 starts, its output shaft transmits rotational power to the drive shaft 102 through a coupling, causing the drive shaft 102 to rotate around its own axis. When the drive shaft 102 rotates, it drives multiple pulleys 104 that are equidistantly fixed on its outer side to rotate synchronously. Under the action of friction, the belt drives the corresponding pulley 104 on the outer side of the driven shaft 103 to rotate, thereby causing the driven shaft 103 to rotate around its own axis. The rotation direction of the driven shaft 103 is the same as that of the drive shaft 102. The belt makes a cyclical motion under the drive of the drive shaft 102 and the driven shaft 103. After the carton is placed on the belt, the friction between the belt and the carton causes the carton to move with the belt, thereby realizing the continuous conveying of the carton on the conveying assembly 1.

[0027] The top and bottom of the conveyor frame 101 are fixedly connected with several support plates 106 at equal intervals, and the support plates 106 at the top and bottom are set one-to-one. The belt is wrapped around the outside of the two support plates 106 at the top and bottom respectively.

[0028] The support plate 106 provides a stable support path for the belt. The top support plate 106 is located below the upper conveying section of the belt, and the bottom support plate 106 is located above the lower return section of the belt. By setting them up in a corresponding manner, the belt is ensured to maintain a horizontal tension during operation, avoiding slippage or deviation caused by belt slack. The support plate 106 provides rigid support for the belt, preventing excessive deformation of the belt due to the weight of the carton board, and ensuring smooth conveying of the carton board.

[0029] The two ends of the support plate 106 are curved. The arc-shaped surface can guide the belt to transition smoothly and avoid local compression deformation or edge wear caused by right-angle edges, thereby extending the service life of the belt.

[0030] The bracket 2 has sleeves 3 symmetrically fixed inside, and the slide rods 4 are slidably connected inside the corresponding sleeves 3. The sleeves 3 make the slide rods 4 more stable when sliding, and the prism-shaped slide rods 4 will not rotate when sliding.

[0031] The guide plate 5 has rounded corners at all four corners. The rounded corners can prevent the guide plate 5 from scratching or damaging the cardboard.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
