Description

Technical Field

[0001] The utility model relates to the technical field of carton production, in particular to a conveying mechanism for a carton production line. Background Art

[0002] The conveying mechanism in the carton production line is a key equipment for improving production efficiency and ensuring the smooth operation of the production process. Its main function is to smoothly and accurately transfer the cartons from one process of the production line to the next process, greatly reducing the labor intensity of manual handling and improving the automation and efficiency of the overall production line. In this process, the conveying mechanism not only bears the weight of the cartons, but also ensures the stability and safety of the cartons during transportation, avoiding damage to the cartons or production delays caused by improper transportation. This type of conveying mechanism is mainly composed of a frame, a transmission device, a conveyor belt and a supporting structure. The frame serves as the supporting body to ensure the stability and durability of the transmission mechanism; the transmission device is driven by a motor to provide continuous power for the conveyor belt. Common transmission methods include electric roller transmission, chain transmission, belt transmission, etc.; the conveyor belt directly carries the cartons, and the selection of its material needs to consider the weight of the cartons, the coefficient of friction, as well as wear resistance and high temperature resistance; the supporting structure is used to support the conveyor belt and the transmission device to ensure that they can operate smoothly; for example, a conveying mechanism for carton production disclosed in the authorization announcement number CN220536654U includes a frame, a synchronous belt is provided on the frame which is connected to the transmission through two gears which are both rotatably connected to the frame, the inner ring of the synchronous belt is evenly provided with a plurality of teeth meshing with the gears, a driving member for driving the synchronous belt to rotate is installed on the frame, and the synchronous belt is evenly provided with Multiple blocking components are fixedly installed on the synchronous belt in the form of passing through the synchronous belt, and the blocking components are convenient for engaging with the gears together with the synchronous belt, that is, ensuring the overall structural stability of the synchronous belt and the transmission stability of the engagement between the synchronous belt and the gears. However, the above technical solution still uses the synchronous belt to translate the carton workpieces to be processed and produced during use. At this time, the carton workpieces can only be transported to a workstation at the same height as the synchronous belt. In actual production, different processes require different workstation heights. For example, in some processing links, operators may need to operate at a higher workstation, while in other links they may need to operate at a lower workstation. If the carton workpieces can only be transported to a workstation at the same height as the synchronous belt, then the height of the production line will need to be adjusted frequently, affecting the progress of the production line.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-5 The utility model provides an embodiment: a conveying mechanism for a carton production line, comprising a stacking frame 1 and a primary double-belt conveying structure 2 and a secondary double-belt conveying structure 3 which are sequentially stacked in the vertical direction inside the stacking frame 1. A motor seat 4 is installed on one side of the back of the stacking frame 1, and a pulley driving module 5 for driving the primary double-belt conveying structure 2 and the secondary double-belt conveying structure 3 to work at the same speed is installed on one side of the outer wall of the motor seat 4. An inverted U-shaped stand 7 is fixed on one side of the stacking frame 1, and a rectangular material rack 8 is slidably installed on one side of the outer wall of the inverted U-shaped stand 7, and the rectangular material rack 8 is slidably installed on the outer wall of the inverted U-shaped stand 7. A gear lifting module 9 for controlling the height of the rectangular material rack 8 is installed on one side outer wall of the material rack 8, an X-axis feed cylinder 10 is installed on the outer wall of the rectangular material rack 8 on one side of the gear lifting module 9, a flat plate 11 is fixed to the top end of the piston rod of the X-axis feed cylinder 10, and a side clamping positioning mechanism 12 for clamping the carton workpiece is installed on one side outer wall of the flat plate 11, a PLC control panel 6 is installed on one side of the surface of the stacking rack 1, and the output end of the PLC control panel 6 is electrically connected to the input end of the pulley drive module 5, the gear lifting module 9, the X-axis feed cylinder 10, and the side clamping positioning mechanism 12 respectively;

[0019] The structures of the primary double-belt conveyor structure 2 and the secondary double-belt conveyor structure 3 have the characteristics of strong load-bearing capacity and stable operation, which can ensure the stability and safety of the carton workpieces during the conveying process. The pulley drive module 5 includes a stepper motor installed on the outer wall of one side of the motor base 4 and a pulley transmission structure installed at the output end of the stepper motor for driving the primary double-belt conveyor structure 2 and the secondary double-belt conveyor structure 3 to work;

[0020] During the operation of the primary double-belt conveyor structure 2 and the secondary double-belt conveyor structure 3, the stepper motor in the pulley drive module 5 drives the primary double-belt conveyor structure 2 and the secondary double-belt conveyor structure 3 to operate synchronously through the pulley transmission structure, so that the primary double-belt conveyor structure 2 and the secondary double-belt conveyor structure 3 convey the carton workpiece at the same speed;

[0021] The gear lifting module 9 includes a worm gear reduction motor 903 mounted on the outer wall of one side of the rectangular material rack 8, a square-mouthed column 901 fixed on the outer wall of one side of the inverted U-shaped frame 7, and a bevel rack 902 fixed on the outer wall of one side of the square-mouthed column 901. The output end of the worm gear reduction motor 903 is equipped with a bevel gear 904, and the bevel gear 904 and the bevel rack 902 are meshed with each other.

[0022] The worm gear reduction motor 903 drives the bevel gear 904 to rotate according to the control signal of the PLC control panel 6. The bevel gear 904 then drives the rectangular material rack 8, the X-axis feed cylinder 10, the flat plate 11, the side clamp type positioning mechanism 12 and other components to move along the vertical direction of the square mouth column 901 and the bevel rack 902, thereby changing the height position of the side clamp type positioning mechanism 12 and the carton. At the same time, the worm gear reduction motor 903 has a self-locking function, can withstand a large load, can stably make each component hover, and achieve accurate height positioning;

[0023] Steel columns 1101 are installed at the back corners of the flat plate 11. One end of the steel column 1101 extends to the outside of the rectangular material rack 8. When the X-axis feed cylinder 10 actively extends and controls the position of the flat plate 11 and the side clamp positioning mechanism 12, the flat plate 11 will maintain a relative sliding state with the rectangular material rack 8 through the steel column 1101, and the steel column 1101 is used to improve the sliding stability of the flat plate 11 and the side clamp positioning mechanism 12.

[0024] The side-clamping positioning mechanism 12 includes two second cylinders 1201 mounted on the outer wall of one side of the flat plate 11, a right-angle clamping arm 1202 vertically slidably mounted on the surface of the flat plate 11, and an H-shaped connector 1203 fixed to the top of the piston rod of the second cylinder 1201. The top and bottom ends of the H-shaped connector 1203 are hinged with connecting rods 1204, one end of the connecting rod 1204 is fixedly connected to the back corner of the right-angle clamping arm 1202, a longitudinal beam 1205 is fixed between the two right-angle clamping arms 1202 in the same Y-axis direction, and notches are provided on both sides of the top and bottom ends of the flat plate 11 for the right-angle clamping arms 1202 to slide into.

[0025] When the side clamp positioning mechanism 12 clamps the carton, the piston rod of the second cylinder 1201 extends, and the piston rod of the second cylinder 1201 drives the H-type connector 1203 to move away from the flat plate 11. Since one end of the connecting rod 1204 is hinged to the H-type connector 1203 and the other end thereof remains fixed with the right-angle clamping arm 1202, the horizontal movement of the H-type connector 1203 is converted into a vertical sliding movement of the right-angle clamping arm 1202 and the longitudinal beam 1205 under the connection of the connecting rod 1204, that is, the two right-angle clamping arms 1202 approach each other to clamp the carton, which can position the edge of the carton workpiece with accurate positioning, thereby ensuring the stability and accuracy of the carton workpiece during the transmission process.

[0026] When the embodiment of the present application is in use, the user first places the carton workpiece to be conveyed and processed in the side clamping positioning mechanism 12, and the side clamping positioning mechanism 12 accurately clamps the carton workpiece. After the side clamping positioning mechanism 12 clamps the carton workpiece, the PLC control panel 6 issues a command and starts the gear lifting module 9. At this time, the gear lifting module 9 lifts the side clamping positioning mechanism 12 and the carton workpiece to the target height through precise gear transmission, until the side clamping positioning mechanism 12 can accurately send the carton workpiece to the entrance of the first-level double-belt conveyor structure 2 or the second-level double-belt conveyor structure 3 after hovering, then the X-axis feed cylinder 10 drives the side clamping positioning mechanism 12 and the carton workpiece to move above the entrance of the first-level double-belt conveyor structure 2 or the second-level double-belt conveyor structure 3, at this time, the side clamping positioning mechanism 12 releases the carton, and the lower surface of the carton is aligned with the first-level double-belt conveyor structure The first-level double-belt conveyor structure 2 or the second-level double-belt conveyor structure 3 contacts the conveyor belt, and the friction of the conveyor belt transmits it smoothly to the next process. In this process, the first-level double-belt conveyor structure 2 is located at a lower height, which is suitable for lighter or smaller carton workpieces, and for heavier or larger carton workpieces, the PLC control panel 6, gear lifting module 9, side clamp type positioning mechanism 12 and other components will transmit them to the second-level double-belt conveyor structure 3. The second-level double-belt conveyor structure 3 is located at a higher height and has a stronger carrying capacity and more stable transmission performance. In this way, through the precise control of the PLC control panel 6 and the close cooperation of various components, the gear lifting module 9, X-axis feed cylinder 10, rectangular material rack 8, side clamp type positioning mechanism 12, stacking rack 1, first-level double-belt conveyor structure 2, second-level double-belt conveyor structure 3 and the like jointly complete the horizontal transmission task of the carton workpiece.
