Description

Technical Field

[0001] The utility model relates to the technical field of packaging carton production, in particular to a positioning device for packaging carton processing. Background Art

[0002] In the field of packaging carton processing, background technology mainly involves positioning, clamping, cutting, folding and other links in the carton processing process. These links are crucial to improving the efficiency, precision and stability of carton processing.

[0003] In the traditional carton processing process, manual or semi-automatic methods are often used to position, clamp and process cardboard. In order to overcome the limitations of traditional processing methods, positioning technology has been continuously developed and applied. In the field of packaging carton processing, positioning technologies mainly include the following:

[0004] 1. Mechanical positioning: Through the design of mechanical structures, such as guide rails, sliders, limit blocks, etc., the cardboard is accurately positioned. This method has a simple structure and low cost, but its accuracy and flexibility are limited.

[0005] 2. Pneumatic positioning: Use air pressure to drive actuators such as cylinders to quickly position and clamp the cardboard. This method has a fast response speed and smooth operation, but its accuracy is greatly affected by air pressure fluctuations and component wear.

[0006] 3. Electromagnetic positioning: Electromagnetic components such as electromagnets generate suction or repulsion to achieve non-contact positioning and clamping of cardboard. This method has high positioning accuracy, fast response speed, and will not damage the cardboard. Utility Model Content

[0007] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a positioning device for processing packaging cartons.

[0008] The top end face of said sliding panel also is provided with an interlocking structure, and the interlocking structure is pivotally connected to the second end of said sliding panel and the interlocking structure is pivotally connected to the second end of said interlocking structure.

[0009] Preferably, the bottoms of the pressing plate, the movable plate and the connecting plate are all located in the same plane.

[0010] Preferably, the limiting block is slidably engaged in the limiting groove.

[0011] Preferably, the plurality of connecting plates are symmetrically arranged with the pressure plate as the axis of symmetry.

[0012] Preferably, an electromagnet is provided inside the pressing plate, and permanent magnets are provided inside the base and the second fixing plate.

[0013] The utility model has the following beneficial effects:

[0014] 1. Precise Positioning and Fixing: Through electromagnet control and precise servo motor drive, the device accurately positions and securely fixes the cardboard. Whether the cardboard is regular or irregular in shape, the movable plate can be adjusted to precisely fit the edge or specific position, ensuring that the cardboard will not shift or deform during processing, thereby greatly improving processing accuracy.

[0015] 2. Strong Adaptability: The device's design fully considers the diversity of cardboard sizes and shapes. Two servo motors independently control the two movable plates, enabling them to move to different positions, creating varying spacing between them and the pressing plate. This unequal positioning capability allows the device to easily handle a variety of irregular shapes and sizes of cardboard, eliminating the need for frequent equipment changes or adjustments, greatly improving the flexibility and adaptability of the production line.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example:

[0022] like Figure 1-3 As shown, the embodiment of the present invention provides a positioning device for processing packaging cartons, including a base 1, a handle 5 and a servo motor 12. The top of the base 1 is fixedly connected to the first fixing plate 2, the top of the first fixing plate 2 is fixedly connected to the second fixing plate 3, the handle 5 is located above the second fixing plate 3, the bottom of the handle 5 is fixedly connected to the fixing rod 4, the fixing rod 4 passes through the second fixing plate 3, the bottom end of the fixing rod 4 is fixedly connected to the pressing plate 6, and the pressing plate 6 contacts the bottom of the second fixing plate 3. A movable plate 7 is provided at the front and rear sides of the pressing plate 6, and the front and rear surfaces of the pressing plate 6 are fixedly connected to two fixing blocks 8, the fixed block 8 is rotatably connected to the connecting plate 9 through a rotating shaft, and a limiting groove 11 is provided on the outer surface of the movable plate 7 near the pressing plate 6. The servo motor 12 is fixedly connected to the inner wall of the limiting groove 11, and the driving end of the servo motor 12 is fixedly connected to a bidirectional screw rod 13. The bidirectional threads of the bidirectional screw rod 13 are threadedly connected to the limiting block 10, and the limiting block 10 and the connecting plate 9 are rotatably connected at one end away from the pressing plate 6 through a rotating shaft.

[0023] By designing the bottoms of the pressing plate 6, the movable plate 7, and the connecting plate 9 to be on the same plane, it is ensured that when the pressing plate 6, the movable plate 7, and the connecting plate 9 press the cardboard, each component can be evenly stressed, avoiding deformation or slippage of the cardboard due to uneven force, thereby improving the stability and reliability of clamping.

[0024] The limit block 10 slides and engages within the limit slot 11. This design restricts the movement of the limit block 10 to a predetermined path. Thus, when the servo motor 12 drives the bidirectional screw 13 to rotate, the limit block 10 can accurately move the movable plate 7 and the connecting plate 9 to the designated position, improving the precision and accuracy of positioning.

[0025] The multiple connecting plates 9 are symmetrically arranged around the pressing plate 6. This layout not only makes the overall structure more compact and aesthetically pleasing, but also allows for simultaneous clamping of multiple areas of the cardboard, improving processing efficiency. Furthermore, the symmetrical layout helps maintain a balanced clamping force, reducing equipment wear and failures caused by unbalanced loading.

[0026] The electromagnet inside the pressure plate 6 works in conjunction with the permanent magnets inside the base 1 and the second fixing plate 3 to achieve fast and convenient suction and release operations. When the electromagnet is energized, it quickly generates a strong suction force, firmly securing the pressure plate 6 to the base 1. When the electromagnet is de-energized, the suction force disappears, allowing the pressure plate 6 to be easily released. This design simplifies the operation process and improves work efficiency.

[0027] Working Principle: When using the positioning device for packaging carton processing, the operator first places the cardboard to be processed steadily on the base 1, ensuring that it is directly below the pressure plate 6. This is the first step in the positioning process and lays the foundation for subsequent steps. By de-energizing the electromagnet within the pressure plate 6, the pressure plate 6, which was originally attracted to the second fixed plate 3 by electromagnetic force, is released, losing its attraction. At this point, the operator manually operates the handle 5 to drive the fixed rod 4, which causes the pressure plate 6 to move downward. This step allows the pressure plate 6 to approach and contact the cardboard on the base 1. Once the pressure plate 6, movable plate 7, and connecting plate 9 have made contact with the cardboard, the operator energizes the electromagnet within the pressure plate 6 again. The energized electromagnet generates an attraction force, firmly adhering the pressure plate 6 to the base 1. During this process, the pressure plate 6, movable plate 7, and connecting plate 9 work together to firmly clamp the cardboard, ensuring stability during subsequent processing. Two servo motors 12 drive the bidirectional screw 13. When the bidirectional screw 13 rotates, the threads on it push the limit block 10 to move along the limit slot 11. The two limit blocks 10 can move in opposite directions or in opposite directions, thereby driving the connecting plate 9 and the movable plate 7 to move. By adjusting the position of the movable plate 7, the distance between it and the pressure plate 6 can be precisely controlled to meet the positioning requirements of cardboards of different sizes or shapes. By adjusting the position of the movable plate 7, it can be made to fit the edge or specific position of the cardboard more accurately, thereby achieving precise positioning of the cardboard. In addition, since the two servo motors 12 can control the two movable plates 7 separately, they can each move to different positions, forming different distances between them and the pressure plate 6. This unequal positioning capability is particularly important for processing cardboards of irregular shapes or varying sizes, because it ensures that every key part of the cardboard can be accurately positioned and fixed.

[0028] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
