Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard printing technology, specifically to a cardboard conveying mechanism for a corrugated cardboard printing machine. Background Technology

[0002] Amidst the booming development of the modern packaging industry, corrugated cardboard boxes, as one of the main packaging forms for the transportation and storage of various products, are experiencing a continuous rise in market demand. With consumers increasingly demanding higher standards for product packaging appearance, and the e-commerce industry strongly promoting personalized and exquisite packaging, the importance of printing quality for corrugated cardboard boxes is becoming increasingly prominent.

[0003] For example, an existing patent (publication number: CN220245037U) discloses a cardboard conveying mechanism for a corrugated carton printing machine, including a fixed plate. The fixed plate has openings on both its left and right ends. A transmission wheel set is movably connected to the inner cavity of each of the left and right openings. A conveyor belt is movably connected to the outside of each of the left and right transmission wheel sets. Support columns are fixedly connected to the four corners of the lower end face of the fixed plate. Vertical plates are fixedly connected to the front and rear of the left side of the upper end face of the fixed plate. A pressing roller is movably connected to the front and rear vertical plates. An adjustment device is provided on the end face of each of the front and rear vertical plates. The adjustment device is movably connected to the pressing roller. A limit device is provided on the right side of the upper end face of the fixed plate.

[0004] However, the above-mentioned corrugated cardboard conveying mechanism for a corrugated box printing machine has some drawbacks in actual use: the device moves the pressing roller vertically by turning the handle and adjusting the distance between the pressing roller and the fixed plate to flatten the material. However, in actual operation, the operator needs to turn both handles simultaneously to make the pressing roller move horizontally and stably downward. This operation is time-consuming and laborious, affecting the working efficiency of the device and reducing economic benefits.

[0005] To address this issue, we designed a corrugated cardboard conveying mechanism for a corrugated box printing machine. Utility Model Content

[0015] The beneficial effects of this utility model are as follows: When the motor is started, it drives the one-way lead screw to rotate. At this time, the first synchronous wheel connected to the motor drive end rotates, driving the synchronous belt to move. At this time, the second synchronous wheel is driven by the friction of the synchronous belt and rotates simultaneously with the first synchronous wheel. The other one-way lead screw is connected to the second synchronous wheel. At this time, the two threaded blocks rotate simultaneously, driving the threaded blocks to move in the vertical direction. Since a pressure plate is connected to the outer wall of the threaded block, when the threaded block moves, the pressure plate can flatten the material on the conveyor belt.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 as well as Figure 2 This utility model provides a technical solution: a cardboard conveying mechanism for a corrugated carton printing machine, including an operation panel 1, a conveyor belt 2 connected to the operation panel 1, a support plate 3 connected to the top surface of the operation panel 1, a groove 303 formed on the outer wall of the support plate 3, a motor 5 mounted on the top surface of the support plate 3, a synchronous pulley 1 connected to the drive end of the motor 5, a one-way lead screw 502 connected to the bottom surface of the synchronous pulley 1, a synchronous belt 501 connected to the outer wall of the synchronous pulley 1, and a synchronous pulley 2 connected to the other end of the synchronous belt 501. The lead screw 502 is set in the groove 303. A guide component is provided on the outer wall of the one-way lead screw 502. There are two one-way lead screws 502. The top surfaces of the two one-way lead screws 502 are respectively connected to the first synchronous pulley and the second synchronous pulley. A threaded block 12 is threadedly connected to the one-way lead screw 502. A pressure plate 11 is connected to the outer wall of the threaded block 12. An L-shaped plate 4 is connected to the top surface of the support plate 3. The motor 5 is connected to the outer wall of the L-shaped plate 4. A protective pad 1101 is connected to the bottom surface of the pressure plate 11. The protective pad 1101 is made of rubber.

[0025] The guide assembly includes a slider 302, a groove 301 is provided in the groove 303, the slider 302 is slidably connected in the groove 301, and the other end of the slider 302 is connected to the outer wall of the threaded block 12.

[0026] It should be noted that the control panel 1 is equipped with a drive component, including a motor 5 and a rolling wheel, which can drive the conveyor belt 2 to move. The control panel 1 is also equipped with a control system, which contains a microcontroller to control the opening and closing of the motor 5 and the electric telescopic rod 8. Since this is existing technology, it will not be described in detail in this specification.

[0027] In practice, when it is necessary to flatten the material on conveyor belt 2, motor 5 is started, driving the one-way lead screw 502 to rotate. At this time, synchronous wheel 1, which is connected to the drive end of motor 5, rotates, driving synchronous belt 501 to move. Synchronous wheel 2 is driven by the friction of synchronous belt 501 and rotates simultaneously with synchronous wheel 1. Another one-way lead screw 502 is connected to synchronous wheel 2. At this time, two threaded blocks 12 rotate simultaneously, driving threaded blocks 12 to move in the vertical direction. Since pressure plate 11 is connected to the outer wall of threaded block 12, when threaded block 12 moves, pressure plate 11 can flatten the material on conveyor belt 2. The above device drives two one-way lead screws 502 to rotate simultaneously through synchronous belt 501, so that pressure plate 11 can move stably to flatten the material, improving work efficiency.

[0028] See Figure 1 as well as Figure 3 As shown, a standing plate 6 is connected to the top surface of the operating panel 1, an electric telescopic rod 8 is provided on the top surface of the standing plate 6, a rack 9 is connected to the telescopic end of the electric telescopic rod 8, a gear 10 is meshed on one side of the rack 9, a straightening plate 7 is connected to the bottom surface of the gear 10, the straightening plate 7 is located outside the standing plate 6, a connecting plate 601 is connected to the top surface of the standing plate 6, and the outer wall of the electric telescopic rod 8 is connected to the connecting plate 601.

[0029] In practice, when the material needs to be straightened on the conveyor belt 2, the electric telescopic rod 8 is activated, and the rack 9 connected to the telescopic end of the electric telescopic rod 8 is moved horizontally. Since one side of the rack 9 is engaged with the gear 10, when the rack 9 moves, it drives the gear 10 to rotate, thereby adjusting the position of the straightening plate 7 and straightening the material on the conveyor belt 2, improving the efficiency of the operation and increasing economic benefits.

[0030] See Figure 3 An extension plate 13 is connected to the outer wall of the standing plate 6. The top surface of the extension plate 13 is connected to the gear 10. A connecting rod 14 is connected to the bottom surface of the gear 10. The other end of the connecting rod 14 passes through the extension plate 13 and is connected to the straightening plate 7.

[0031] In practice, the angle is adjusted by rotating the gear 10 on the straightening plate 7, and a certain distance is set between the straightening plate 7 and the conveyor belt 2 to prevent motion interference between the straightening plate 7 and the conveyor belt 2.

[0032] See Figure 4 as well as Figure 5The operating panel 1 has a slot 102, and a double-acting lead screw 603 is installed in the slot 102. A threaded block 602 is threadedly connected to the double-acting lead screw 603. The top surface of the threaded block 602 is connected to the bottom surface of the standing plate 6. A sliding component is also provided on the top surface of the operating panel 1. A limit component is provided on the outer wall of the threaded block 602. A turntable 604 is provided at the other end of the double-acting lead screw 603. The sliding component includes a T-slot and a T-block. The T-slot is opened on the top surface of the operating panel 1, and the T-block is slidably engaged in the T-slot. The top surface of the plate is connected to the bottom surface of the standing plate 6. Since this is prior art, it will not be described in detail in this specification, nor is it shown in the figure. The limiting component includes a strip block and a strip groove. The strip groove is opened on the inner wall of the empty groove 102. The strip block is slidably connected in the strip groove. The outer wall of the strip block is connected to the outer wall of the threaded block 602. One end of the bidirectional lead screw 603 is connected to a rotating rod, and the other end of the rotating rod is connected to the turntable 604. Through the above device, the distance between the standing plates 6 can be adjusted to further correct the material.

[0033] See Figure 1 The bottom surface of the control panel 1 is connected to a support leg 101. There are multiple support legs 101, which are symmetrically distributed in pairs at the four corners of the bottom surface of the control panel 1. The support legs 101 support the control panel 1 to ensure the stable operation of the device.

[0034] Working principle: When it is necessary to flatten the material on conveyor belt 2, start motor 5 to drive one-way screw 502 to rotate. At this time, synchronous pulley 1, which is connected to the drive end of motor 5, rotates, driving synchronous belt 501 to move. Synchronous pulley 2 is driven by the friction of synchronous belt 501 and rotates simultaneously with synchronous pulley 1. Another one-way screw 502 is connected to synchronous pulley 2. At this time, two threaded blocks 12 rotate simultaneously, driving threaded blocks 12 to move in the vertical direction. Since pressure plate 11 is connected to the outer wall of threaded block 12, when threaded block 12 moves, pressure plate 11 can flatten the material on conveyor belt 2. The above device is driven by synchronous belt 501. Two unidirectional lead screws 502 rotate simultaneously, enabling the pressure plate 11 to move stably and flatten the material, thus improving work efficiency. A protective pad 1101 is connected to the bottom of the pressure plate 11, providing protection for the material during operation. When the material needs to be straightened on the conveyor belt 2, the electric telescopic rod 8 is activated, causing the rack 9 connected to its telescopic end to move horizontally. Since one side of the rack 9 meshes with the gear 10, its movement drives the gear 10 to rotate, adjusting the position of the straightening plate 7 and straightening the material on the conveyor belt 2, thereby improving work efficiency and economic benefits.
