Description

Technical Field

[0001] This utility model belongs to the field of cardboard box printing technology, specifically relating to a positioning mechanism for corrugated cardboard box printing. Background Technology

[0002] Precise positioning is crucial for ensuring print quality during the printing process of corrugated cardboard boxes. Traditional positioning mechanisms typically rely on mechanical clamps or baffles for fixation, but these have significant limitations in practical applications. Firstly, ordinary mechanical clamps often apply considerable pressure to maintain stability, easily creating indentations on the cardboard surface or even damaging the internal corrugated structure, affecting packaging strength. Secondly, corrugated cardboard itself has a certain degree of elasticity and warping tendency; constraining it only from the side or bottom makes it difficult to ensure the printed surface remains absolutely flat throughout the process, easily leading to ghosting or misalignment of the printed pattern due to minute displacements. Furthermore, the static charge generated during high-speed printing causes dust and impurities from the environment to adhere to the cardboard surface, potentially causing thin cardboard boxes to stick together due to electrostatic adhesion, making separation or precise positioning difficult, further affecting printing cleanliness and operational efficiency. Therefore, we propose a positioning mechanism for corrugated cardboard box printing. Utility Model Content

[0003] The purpose of this invention is to provide a positioning mechanism for corrugated cardboard box printing, which can solve the problems in related technologies such as displacement and warping caused by insecure fixing, dust adsorption caused by static electricity accumulation, and poor adaptability of traditional mechanical clamping that easily damages the cardboard box.

[0004] The specific technical solution adopted by this utility model is as follows: A positioning mechanism for printing corrugated cardboard boxes includes a positioning plate, a limiting plate is provided at one end of the top of the positioning plate, sliding grooves are provided on both sides inside the positioning plate, and a clamping component is provided inside the positioning plate. The clamping assembly includes a bidirectional motor disposed inside the positioning plate. Both ends of the bidirectional motor are splinedly connected to transmission rods. One end of the transmission rod is provided with a threaded rod. A bearing is threadedly connected to the surface of the threaded rod. A sliding plate is provided on the surface of the bearing. The surface of the sliding plate is slidably connected to the inside of the sliding groove. A clamping plate is provided on the top of the sliding plate.

[0005] One end of the positioning plate is equipped with a buffer plate, and one end of the clamping plate has several sets of anti-slip grooves. These anti-slip grooves increase the friction between the clamping plate and the side wall of the corrugated carton. These dense grooves create a rough contact surface, allowing the clamping plate to more effectively "grip" the surface of the carton when clamped, preventing it from sliding or rotating during the printing process due to machine vibration or force, thus ensuring the firmness and accuracy of the positioning.

[0006] The controller body is located on the top of the back of the limiting plate, a flow groove is provided in the middle of the surface of the limiting plate, and a guide frame is provided on the back of the flow groove.

[0007] A negative pressure fan is provided on the back of the guide frame. The output end of the controller body is electrically connected to the input end of the negative pressure fan and the bidirectional motor through a power cord. The function of the negative pressure fan is to firmly adhere the corrugated carton to the surface of the limiting plate by generating a strong suction force, so as to ensure that it remains flat and stable during the printing process and does not shift or warp.

[0008] The bottom of the limiting plate surface has a groove, and a fiber conductive plate is arranged inside the groove. The function of the fiber conductive plate is to collect and conduct static charge. It directly contacts the surface of the corrugated cardboard box and uses its own conductive properties to effectively collect the static charge generated during the printing process.

[0009] The back of the fiber conductive plate is provided with a connecting line, and the bottom of the connecting line is provided with a grounding plate. The connecting line and the grounding plate together form a reliable electrostatic discharge path. Its function is to collect the static charge generated by friction on the surface of the corrugated cardboard box through the fiber conductive plate, and then guide it to the grounding plate through the connecting line, and finally safely conduct it to the ground, thereby effectively eliminating static electricity and preventing static electricity from attracting dust or interfering with the printing process.

[0010] Both sides of the top of the grounding plate are provided with threaded grooves, and grounding screws are threadedly connected inside the two sets of threaded grooves.

[0011] The technical effects achieved by this utility model are as follows: 1. This utility model, through the setting of the clamping assembly, utilizes a bidirectional motor to synchronously drive the transmission rods and threaded rods on both sides to rotate, causing the bearings to drive the sliding plate to move smoothly along the sliding groove. This, in turn, pushes the two sets of clamping plates in opposite directions to adaptively clamp and fix the corrugated carton. This ensures the carton's stable position during printing, preventing displacement. The bidirectional adjustment allows for flexible adaptation to cartons of different sizes, effectively improving positioning accuracy and operational efficiency, while reducing the complexity of manual adjustments and enhancing the overall reliability and adaptability of the printing operation.

[0012] 2. This utility model, through the arrangement of a flow channel, guide frame, negative pressure fan, fiber conductive plate, connecting wire, and grounding plate, generates a strong directional adsorption force, firmly and flatly adsorbing the corrugated cardboard box onto the surface of the limiting plate, providing a solid guarantee for subsequent printing. Simultaneously, the fiber conductive plate, connected to the grounding plate via the connecting wire, forms a reliable electrostatic discharge path, which can promptly conduct static charges generated during the printing process to the ground, fundamentally preventing the problem of electrostatic adsorption of dust or paper sticking and misalignment, significantly improving the finished product quality and production stability.

[0015] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0016] like Figures 1-5 As shown, a positioning mechanism for printing corrugated cardboard boxes includes a positioning plate 1, a limiting plate 5 is provided at one end of the top of the positioning plate 1, sliding grooves 3 are provided on both sides inside the positioning plate 1, and a clamping component 4 is provided inside the positioning plate 1. The clamping assembly 4 includes a bidirectional motor 401 disposed inside the positioning plate 1. Both ends of the bidirectional motor 401 are splinedly connected to a transmission rod 402. One end of the transmission rod 402 is provided with a threaded rod 403. A bearing 404 is threadedly connected to the surface of the threaded rod 403. A sliding plate 405 is provided on the surface of the bearing 404. The surface of the sliding plate 405 is slidably connected to the inside of the sliding groove 3. A clamping plate 406 is provided on the top of the sliding plate 405.

[0017] A buffer plate 2 is provided at one end of the positioning plate 1. The main function of the buffer plate 2 is to buffer and guide the carton when it is placed in, so as to prevent the edges of the carton from being deformed or damaged due to impact. Several anti-slip grooves are provided at one end of the clamping plate 406.

[0018] The controller body 6 is located on the top of the back of the limiting plate 5. A flow groove 7 is formed in the middle of the surface of the limiting plate 5. A guide frame 8 is located on the back of the flow groove 7. The function of the guide frame 8 is to construct and guide the negative pressure airflow channel. It is connected to the back of the flow groove 7, which constricts an open surface air intake area and guides it to the inlet of the negative pressure fan 9.

[0019] A negative pressure fan 9 is installed on the back of the guide frame 8. The output terminals of the controller body 6 are electrically connected to the negative pressure fan 9 and the input terminals of the bidirectional motor 401 via power cords. When the negative pressure fan 9 is started, it continuously draws air away from the surface of the limiting plate 5 through the guide frame 8 and the flow channel 7, thereby forming a strong negative pressure zone on the entire surface where the corrugated carton contacts the limiting plate 5. This negative pressure generates a uniform suction force, pressing the carton tightly against the limiting plate 5, keeping its back side absolutely flat and tightly fitted to the limiting plate 5.

[0020] A groove is provided at the bottom of the surface of the limiting plate 5, and a fiber conductive plate 10 is disposed inside the groove. The groove facilitates the placement of the fiber conductive plate 10, which collects and conducts static charge. It directly contacts the surface of the corrugated cardboard box and effectively collects the static charge generated during the printing process by utilizing its own conductive properties.

[0021] A connecting line 11 is provided on the back of the fiber conductive plate 10, and a grounding plate 12 is provided at the bottom of the connecting line 11. The connecting line 11 and the grounding plate 12 together form a reliable static discharge path. Its function is to collect the static charge generated by friction on the surface of the corrugated cardboard box through the fiber conductive plate 10, and then guide it to the grounding plate 12 through the connecting line 11, and finally safely conduct it to the ground, thereby effectively eliminating static electricity and preventing static electricity from attracting dust or interfering with the printing process.

[0022] Both sides of the top of the grounding plate 12 are provided with threaded grooves, and grounding screws are threaded into the interior of both sets of threaded grooves. The function of the grounding screws is to establish a permanent and reliable physical connection between the entire static electricity elimination system and the ground. By being forcefully screwed into the grounding electrode or grounding grid, it ensures that the grounding plate 12 can continuously and with low resistance conduct static charge into the ground.

[0023] In summary: By using the clamping assembly 4, the bidirectional motor 401 synchronously drives the transmission rods 402 and threaded rods 403 on both sides to rotate, causing the bearing 404 to drive the sliding plate 405 to move smoothly along the sliding groove 3. This, in turn, pushes the two sets of clamping plates 406 in opposite directions to adaptively clamp and fix the corrugated carton. This ensures the stability of the carton's position during printing, preventing displacement. The bidirectional adjustment enables flexible adaptation to cartons of different sizes, effectively improving positioning accuracy and operational efficiency, while reducing the complexity of manual adjustments and enhancing the overall reliability and adaptability of the printing operation.

[0024] The arrangement of the flow channel 7, guide frame 8, negative pressure fan 9, fiber conductive plate 10, connecting line 11, and grounding plate 12 generates a strong directional adsorption force, firmly and flatly adsorbing the corrugated cardboard box onto the surface of the limiting plate 5, providing a solid guarantee for subsequent printing. Simultaneously, the fiber conductive plate 10, connected to the grounding plate 12 via the connecting line 11, forms a reliable electrostatic discharge path, effectively conducting static charges generated during printing to the ground, fundamentally preventing the problem of electrostatic adsorption of dust or paper sticking and misalignment, significantly improving the finished product quality and production stability.

[0025] The operating steps of this device are as follows: First, the operator places the corrugated cardboard box onto the positioning plate 1 via the buffer plate 2, ensuring one side is flush against the limiting plate 5. Then, the external power supply is connected, and the equipment is started. The bidirectional motor 401 synchronously drives the transmission rods 402 on both sides, causing the threaded rod 403 to rotate, which in turn moves the sliding plate 405 and its clamping plate 406 towards the center, thus clamping and fixing the cardboard box from both sides. Simultaneously, the negative pressure fan 9 starts working, using the suction generated by the flow channel 7 and the guide frame 8 to firmly adhere the cardboard box to the surface of the limiting plate 5. During the printing process, the fiber conductive plate 10 continuously conducts the generated static charge to the ground via the connecting line 11 and the grounding plate 12.

[0026] The working principle of this device is as follows: the clamping component 4, through mechanical transmission by the bidirectional motor 401, precisely clamps the sides of the carton laterally, effectively preventing horizontal displacement. Simultaneously, the negative pressure system, through airflow adsorption, firmly presses the entire carton against the surface of the limiting plate 5, achieving both vertical positioning and eliminating warping. Combined with the grounding and conduction mechanism of the static electricity elimination system, static charges generated during operation can be promptly discharged. This creates a stable and reliable printing environment, comprehensively ensuring the carton's stable position during the printing process and the quality of the finished product.

[0027] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
