Description

Technical Field

[0001] This utility model relates to the field of cardboard wrapping machine technology, and in particular to an adjustable one-piece cardboard wrapping machine gripping device. Background Technology

[0002] Automatic case packers, a product of modern packaging industry and containerized transportation development, are a new type of packaging equipment that has emerged in the last thirty years, integrating mechanical, electrical, optical, and pneumatic technologies. Their core function is to automate transport packaging: through preset arrangement rules and quantitative loading, they accurately pack finished products into cartons and complete the closing or sealing of the carton openings. Currently, this equipment plays a crucial role in beer and beverage production lines both domestically and internationally, significantly improving packaging efficiency and standardization.

[0003] Currently, the mainstream types of carton packers on the market include pneumatic gripper and one-piece packers. One-piece packers, with their compact design, offer advantages such as small footprint and low energy consumption. Furthermore, their highly integrated functionality allows for operation by a single person, eliminating the need for additional gluing processes, thus combining environmental friendliness and economy. Although existing one-piece packer technology is relatively mature, it still has limitations when dealing with diverse carton specifications. When the type or size of the carton changes, the traditional gripper structure requires adjustment through disassembly and replacement of adaptable components. This process is not only time-consuming and labor-intensive but also directly leads to a decrease in production efficiency.

[0004] To address this issue, we propose an adjustable one-piece carton wrapping machine gripping device to solve the problem that existing one-piece carton packing machine grippers cannot adapt to different carton sizes. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide an adjustable one-piece carton wrapping machine gripping device to solve the problem that the existing one-piece carton packing machine grippers cannot adapt to cartons of different specifications.

[0006] To achieve the above and other related objectives, this utility model provides an adjustable one-piece carton wrapping machine gripping device, including: an adjustment component, several grippers, and a stabilizing component;

[0007] The gripper includes four adjusting grippers and two positioning grippers;

[0008] The adjustment assembly includes a support column, two adjusting devices are provided below the support column, and a bracket is connected to the upper end of each of the two adjusting devices. The support column passes through the middle of the two brackets. Two symmetrical adjusting claws are connected to the lower end of each of the two adjusting devices. Each adjusting device is used to adjust the distance between the corresponding two adjusting claws. The two adjusting devices have an X-shaped structure and are layered. An electric telescopic rod is connected between the side walls of the two adjusting devices.

[0009] The stabilizing component is located outside the adjusting component and is used to enhance the stability of the gripper during the clamping and moving process.

[0010] Preferably, the bracket is U-shaped and the middle part of the bracket is annular, and the lower end of the support extends outward to form a flange.

[0011] Preferably, both of the adjusting devices include a square guide rail, the lower end of which has two symmetrical grooves, each groove containing a slider, and each slider can slide within the corresponding groove. A bidirectional screw is provided in the middle of the guide rail, passing through the two sliders and parallel to the long sides of the two grooves. A motor is mounted on the side of the guide rail, and the output end of the motor passes through the side wall of the guide rail and is connected to the end of the bidirectional screw. The lower end of each slider is connected to an adjusting claw.

[0012] Preferably, the opposite sides of the support are connected to two positioning claws, and each positioning claw is connected to two adjusting claws on the same side.

[0013] Preferably, each of the positioning claws is connected to a telescopic rod one, and each of the support column and the two positioning claws is connected to a telescopic rod two.

[0035] like Figure 1-5 As shown, this utility model provides an adjustable one-piece carton wrapping machine gripping device, including: an adjustment component 1, several grippers 2 and a stabilizing component 3.

[0036] The gripper 2 includes four adjusting grippers 20 and two positioning grippers 21. The adjusting grippers 20 are located at the four corners of all grippers 2, and the positioning grippers 21 are located at the middle of both sides of all grippers 2.

[0037] The adjustment assembly 1 includes a support column 10, with two adjusting devices 11 located below the support column 10. Each adjusting device 11 has a bracket 12 connected to its upper end. The support column 10 passes through the middle of the two brackets 12, and the brackets 12 can rotate around the support column 10. Each adjusting device 11 has two symmetrical adjusting claws 20 connected to its lower end. Each adjusting device 11 is used to adjust the distance between the corresponding two adjusting claws 20. The two adjusting devices 11 have an X-shaped structure and are layered. An electric telescopic rod 13 is connected between the side walls of the two adjusting devices 11. The angle of the two adjusting devices 11 on the horizontal plane is adjusted by extending and retracting the electric telescopic rod 13. This structure controls the distance between the adjusting claws 20 through the two adjusting devices 11 and changes the shape of the four adjusting claws 20 using the electric telescopic rod 13, thus adapting to different types of square cartons, expanding its application range, reducing operational difficulty, and improving practicality.

[0038] The stabilizing component 3 is located outside the adjusting component 1 and is used to enhance the stability of the gripper 2 during the clamping and moving process.

[0039] In one embodiment, please refer to Figure 2 The support 12 has a U-shaped structure and a circular ring in the middle. It is connected to the support column 10 through the circular ring, allowing the support 12 to rotate around the support column 10. The lower end of the support column 10 extends outward to form a flange 100, which supports the support 12 and prevents the support 12 from falling off the support column 10.

[0040] In one embodiment, please refer to Figure 3 Both adjusters 11 include a square guide rail 110. The lower end of the guide rail 110 has two symmetrical grooves 111, each containing a slider 112. Each slider 112 can slide within its corresponding groove. A bidirectional screw 113 is located in the middle of the guide rail 110, passing through both sliders 112 and parallel to the long sides of the two grooves 111. The bidirectional screw 113 is threadedly connected to both sliders 112, with opposite thread directions. A motor 114 is mounted on the side of the guide rail 110. The output end of the motor 114 passes through the side wall of the guide rail 110 and connects to the end of the bidirectional screw 113. The lower end of each slider 112 is connected to an adjusting claw 20. In use, the motor 114 is started, driving the bidirectional screw 113 to rotate. The bidirectional screw 113 controls the two sliders 112 to move closer or further apart, thus controlling the distance between adjacent adjusting claws 20.

[0041] In one embodiment, please refer to Figure 1-3Each support column 10 is connected to two positioning claws 21 on opposite sides, and each positioning claw 21 is connected to two adjusting claws 20 on the same side. Specifically, a telescopic rod 22 is connected between each positioning claw 21 and the two adjusting claws 20 on the same side. The telescopic rod 22 is used to determine the position of the positioning claw 21, so that the two positioning claws 21 can only move back and forth. A telescopic rod 23 is connected between each support column 10 and the two positioning claws 21. The telescopic rod 23 makes the positioning claws 21 on the same side and the two adjusting claws 20 coplanar, preventing the grippers 2 from rotating when the electric telescopic rod 13 is working, which would cause misalignment with the packaging box and affect gripping.

[0042] In one embodiment, please refer to Figure 4 The outer side wall of the relative positioning claw 20 extends outward to form a support rod 24. All relative support rods 24 are connected by a telescopic rod 25. The telescopic rod 25 cooperates with the support rod 24 to protect the side wall of the packaging box, preventing the carton from falling off during movement. A vertical sponge board 26 is connected to the side wall of the telescopic rod 25 on the same side. The sponge board 26 further enhances the protection of the carton, preventing damage caused by impact with the telescopic rod 25.

[0043] In one embodiment, please refer to Figure 5 The stabilizing component 3 includes a crane 30, with a lifting ring 31 located below the crane 30. An auxiliary hydraulic push rod 32 connects the crane 30 and the lifting ring 31. Two rotating rings 33 are connected to the inner wall of the lifting ring 31. Both sides of the two supports 12 extend outward and connect to the rotating rings 33. The supports 12 are connected to the lifting ring 31 through the rotating rings 33, increasing the contact area of ​​the adjusting component 1, thereby improving the stability of the equipment during operation, reducing shaking, and protecting the cardboard box and its contents.

[0044] In one embodiment, please refer to Figure 5 The main hydraulic push rod 34 is connected to the middle of the overhead crane 30. The lower end of the main hydraulic push rod 34 is connected to the top of the support column 10. The lifting and lowering operation of the gripper 2 is realized through the cooperation of the main hydraulic push rod 34 and the auxiliary hydraulic push rod 32, which facilitates the handling of the carton.

[0045] The specific usage process of this utility model is as follows: According to the type and specifications of the carton, start the electric telescopic rod 13 to change the included angle of the two guide rails 110 in the horizontal angle, so that the guide rails 110 are parallel to the two diagonal lines of the carton on the horizontal plane. Start the two motors 114, and the motors 114 drive the bidirectional screw 113 to rotate. The bidirectional screw 113 controls the two sliders 112 connected to it to move closer or further away from each other. The sliders 112 make the adjusting claws 20 correspond to the four corners of the carton. During the movement of the adjusting claws 20, the telescopic rods 1 22, 23 and 3 25 change accordingly, so that the positioning claws 21 on the same side are coplanar with the adjusting claws 20. Through the main hydraulic push rod 34 and the auxiliary hydraulic push rod 32, control the claws 2 to descend and perform the gripping operation on the carton.

[0046] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
