Description

Technical Field

[0001] This utility model relates to the field of material feeding equipment technology, and in particular to a material feeding structure for defective products in a card tag production line. Background Technology

[0002] In the card hangtag manufacturing industry, with the diversification of market demands and the continuous changes in product specifications, production line equipment needs to possess greater flexibility and adaptability. Currently, the existing defective product unloading structure of card hangtag production lines has significant limitations in handling different production tasks.

[0003] Traditional defective product unloading structures typically employ a fixed design. Key components, such as the mounting structure for fixing the plates to move on the climbing posts, often cannot be flexibly adjusted according to actual production needs. When producing different sizes of card tags or needing to replace climbing posts of different sizes, the entire unloading structure requires large-scale disassembly and reinstallation, a cumbersome and complex process that consumes significant time and labor costs.

[0004] Furthermore, in the production of card hang tags, the stability and reliability of the defective product unloading structure are crucial to ensuring the normal operation of the production line and product quality. However, in the long-term use of existing card hang tag production lines, the defective product unloading structure often experiences problems such as structural loosening and component detachment, leading to frequent production failures and affecting production efficiency and product quality.

[0005] Currently, many defective product unloading structures have poorly designed limiting mechanisms, resulting in low precision in the fit between limiting components and an inability to effectively guarantee the stability of the fixed plate's vertical movement on the climbing column. During production, due to equipment vibration and impact, the limiting components are prone to loosening or displacement, causing deviations in the fixed plate's movement trajectory. This can lead to the unloading hook failing to accurately pick up defective products, and may even cause safety accidents. Therefore, we provide a defective product unloading structure for card tag production lines. Utility Model Content

[0006] To address the aforementioned problems, this utility model proposes a defective product unloading structure for a card tag production line, which more accurately solves the problems mentioned in the background art.

[0007] This utility model is achieved through the following technical solution:

[0008] The utility model proposes a defective product unloading structure for a card tag production line, including a climbing column and a fixing plate. The surface of the fixing plate is provided with a strip-shaped through groove for sliding around the periphery of the climbing column. A servo motor is fixedly installed on the lower surface of the fixing plate, and a unloading hook is fixedly installed on the output end of the servo motor for hooking up defective products for unloading.

[0009] A climbing structure is installed on the fixed plate for moving the fixed plate up and down;

[0010] The climbing structure includes an L-shaped mounting plate that is slidably mounted on the upper surface of the fixed plate. A servo motor is fixedly mounted on the L-shaped mounting plate. A grinding wheel is fixedly connected to the output end of the servo motor for rotating to move the fixed plate up and down on the side of the climbing column.

[0011] A spacing adjustment assembly is connected between the two L-shaped mounting plates.

[0012] Furthermore, the spacing adjustment assembly includes a second strip-shaped through groove formed on the surface of the fixed plate and a T-shaped slider fixedly installed on the lower surface of the L-shaped mounting plate. The T-shaped slider is slidably connected to the inner wall of the second strip-shaped through groove. A limit mechanism is connected between the fixed plate and the L-shaped mounting plate for stabilizing the two L-shaped mounting plates after the spacing is adjusted.

[0013] Furthermore, the limiting mechanism includes a limiting insertion hole on the surface of the fixed plate and a strip groove on the surface of the L-shaped mounting plate. A vertical rod is fixedly connected between the two end walls of the strip groove. A spring is sleeved around the periphery of the vertical rod. A sliding sleeve block is slidably sleeved around the periphery of the vertical rod. An overlapping plate is fixedly connected to the surface of the sliding sleeve block. A limiting insertion rod is fixedly welded to the overlapping plate at the surface of the fixed plate.

[0014] Furthermore, the sliding sleeve is slidably connected to the inner wall of the strip groove, and the two ends of the overlapping plate are fixedly connected to pull handles for applying force to move the overlapping plate upward.

[0015] Furthermore, the lower end of the limiting rod is inserted into the inner wall of the limiting hole, and the inner diameter of the limiting hole is adapted to the outer diameter of the limiting rod.

[0016] Furthermore, the upper end of the spring is fixedly connected to the end wall of the strip groove, and the lower end of the spring is fixedly connected to the upper surface of the sliding sleeve block.

[0017] The beneficial effects of this utility model are:

[0018] This invention significantly improves operational convenience and adjustment flexibility through the design of a spacing adjustment component and a matching limiting mechanism. In the spacing adjustment component, the sliding engagement of the T-shaped slider and the second strip groove allows for easy adjustment of the spacing between the two L-shaped mounting plates to accommodate climbing columns of different specifications or meet diverse production needs. The limiting mechanism includes a pull handle, providing operators with a convenient point of force application. Simply grasp the handle and pull the overlapping plate upwards to disengage the limiting socket, quickly releasing the L-shaped mounting plate from its limiting position, allowing for free spacing adjustment. After adjustment, releasing the pull handle causes the limiting socket to automatically insert into the limiting socket under spring action, achieving rapid fixation. This design avoids complex operating procedures and cumbersome disassembly and installation steps, greatly saving adjustment time, improving production efficiency, enabling the production line to quickly adapt to different production tasks, and enhancing the equipment's versatility and adaptability.

[0019] This invention ensures that the inner diameter of the limiting hole in the limiting mechanism is matched with its designed outer diameter, guaranteeing a tight fit and preventing the L-shaped mounting plate from shaking or shifting during operation. This ensures the stability of the fixed plate's vertical movement on the climbing column, allowing the unloading hook to accurately pick up defective products for unloading. Simultaneously, the reliable connection between the spring, the upright rod, and the sliding block provides stable power for the automatic reset of the limiting hole, ensuring the normal operation of the limiting mechanism. Furthermore, reliable connections between components, such as bolts and welding, ensure the overall structural robustness, reducing production failures caused by loose or detached components, improving equipment reliability and lifespan, and lowering maintenance costs and the risk of production interruptions.

[0024] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model. Example

[0025] like Figures 1-3 As shown in the figure, an embodiment of this utility model proposes a defective product unloading structure for a card tag production line. This structure mainly consists of a climbing column 1 and a fixed plate 2. A strip-shaped through-slot 3 is formed on the surface of the fixed plate 2, through which the fixed plate 2 is slidably fitted onto the periphery of the climbing column 1. A servo motor 9 is bolted to the lower end surface of the fixed plate 2, and a unloading hook 10 is fixedly installed at the output end of the servo motor 9 via a coupling or other connection method. When the servo motor 9 is started, the unloading hook 10 can rotate, thereby hooking defective products for unloading. Simultaneously, a climbing structure is installed on the fixed plate 2. Specifically, an L-shaped mounting plate 6 is slidably installed on the upper surface of the fixed plate 2. This sliding installation is achieved by setting a slide rail on the fixed plate 2 and a groove on the L-shaped mounting plate 6 that matches the slide rail. A servo motor 7 is bolted to the L-shaped mounting plate 6, and a grinding wheel 8 is fixedly connected to the output end of the servo motor 7 via a key connection or other method. When the servo motor 7 is started, the grinding wheel 8 rotates, and the friction between the grinding wheel 8 and the climbing column 1 enables the fixing plate 2 to move up and down on the side of the climbing column 1. In addition, a spacing adjustment component is connected between the two L-shaped mounting plates 6 to adjust the spacing between the two L-shaped mounting plates 6 to adapt to different specifications of climbing columns 1 or other production needs.

[0026] Furthermore, a second strip-shaped groove 4 is formed on the surface of the fixed plate 2. A T-shaped slider 5 is fixedly installed on the lower surface of the L-shaped mounting plate 6 by welding or other means. The T-shaped slider 5 is slidably connected to the inner wall of the second strip-shaped groove 4, allowing the L-shaped mounting plate 6 to slide within the second strip-shaped groove 4 via the T-shaped slider 5, thereby adjusting the distance between the two L-shaped mounting plates 6. Simultaneously, a limiting mechanism is connected between the fixed plate 2 and the L-shaped mounting plate 6 for stabilizing the two L-shaped mounting plates 6 after the distance is adjusted. This limiting mechanism can fix the L-shaped mounting plates 6 after the distance is adjusted to the appropriate position, preventing them from moving during operation.

[0027] Furthermore, a limiting insertion hole 11 is made on the surface of the fixed plate 2, and a strip groove 12 is made on the surface of the L-shaped mounting plate 6. A vertical support rod 13 is fixedly connected between the two end walls of the strip groove 12 by welding or other means. A spring 14 is sleeved around the periphery of the vertical support rod 13, and the upper end of the spring 14 is fixedly connected to the end wall of the strip groove 12 by welding or other means. A sliding sleeve block 15 is slidably sleeved around the periphery of the vertical support rod 13, and the lower end of the spring 14 is fixedly connected to the upper surface of the sliding sleeve block 15 by welding or other means. A lap plate 16 is fixedly connected to the surface of the sliding sleeve block 15 by welding or other means. A limiting insertion rod 17 is fixedly welded to the surface of the lap plate 16 relative to the surface of the fixed plate 2 by welding or other means. When it is necessary to adjust the spacing of the L-shaped mounting plates 6, the lap plate 16 is pulled upwards, causing the sliding sleeve block 15 to slide on the vertical support rod 13, compressing the spring 14, causing the limiting insertion rod 17 to disengage from the limiting insertion hole 11, and then the spacing of the L-shaped mounting plates 6 is adjusted. Once the spacing is adjusted to the appropriate level, the overlapping plate 16 is loosened. Under the elastic force of the spring 14, the sliding sleeve 15 drives the overlapping plate 16 to move downward, so that the lower end of the limiting rod 17 is inserted into the inner wall of the limiting hole 11, thereby achieving the limiting and fixing of the L-shaped mounting plate 6.

[0028] Furthermore, pull handles 18 are fixedly connected to both ends of the overlapping plate 16 by welding or other means. The shape and size of the pull handles 18 can be designed according to actual usage requirements, such as a cylindrical or square shape that is easy to grip. When it is necessary to adjust the spacing of the L-shaped mounting plates 6, the operator can apply an upward force to the overlapping plate 16 by gripping the pull handles 18, causing the overlapping plate 16 to move upward, thereby driving the limiting rod 17 to disengage from the limiting hole 11, facilitating the spacing adjustment operation.

[0029] Furthermore, it is ensured that the lower end of the limiting rod 17 can be inserted into the inner wall of the limiting hole 11, and that the inner diameter of the limiting hole 11 is compatible with the outer diameter of the limiting rod 17. In actual processing, precise measurement and machining processes ensure the dimensional accuracy of the limiting hole 11 and the limiting rod 17, allowing the limiting rod 17 to be smoothly inserted into the limiting hole 11 and to fit tightly after insertion, preventing the L-shaped mounting plate 6 from shaking during operation.

[0030] Furthermore, the upper end of the spring 14 is fixedly connected to the end wall of the strip groove 12 by welding or other means, and the lower end of the spring 14 is fixedly connected to the upper surface of the sliding sleeve block 15 by welding or other means. During the adjustment of the spacing of the L-shaped mounting plate 6, when the overlapping plate 16 is pulled upward, the sliding sleeve block 15 slides on the upright rod 13, compressing the spring 14 and storing elastic potential energy. When the spacing is properly adjusted, the overlapping plate 16 is released, the spring 14 releases its elastic potential energy, pushes the sliding sleeve block 15 downward, and drives the overlapping plate 16 and the limiting rod 17 downward, so that the limiting rod 17 is inserted into the limiting hole 11, thereby achieving the limiting and fixing of the L-shaped mounting plate 6.
