Description

Technical Field

[0001] This utility model relates to the field of automated packaging equipment technology, and in particular to a telescopic device for an automatic box packer. Background Technology

[0002] In modern industrial production, automatic case packers are an indispensable key piece of equipment for achieving packaging automation. In order to complete processes such as loading items into cases or positioning and transferring cases, automatic case packers usually need to be equipped with telescopic devices to enable the reciprocating motion of the working parts on a predetermined track.

[0003] Currently, there are various driving methods for this type of telescopic device. Among them, using a cylinder to directly drive the slide table for linear reciprocating motion is a common technical solution. Although this direct drive method has a simple structure and fast response speed, it is prone to generating large impacts and vibrations during the start-up and stop phases, especially during high-speed operation.

[0004] Such mechanical impacts not only affect the accuracy of box positioning, causing box displacement and impacting subsequent processes, but may also damage the items inside the box. Furthermore, long-term vibration accelerates the wear and tear of equipment components, reducing the stability and reliability of the entire production line. Therefore, designing a structure that can ensure both extension and retraction speeds while achieving smooth and precise start-stop control and reducing motion impact has become a pressing technical problem to be solved in this field.

[0005] Therefore, this utility model proposes a telescopic device for an automatic box packing machine to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems in the prior art of the telescopic device for automatic box packing machines, such as the easy generation of impact vibration during the telescopic process, resulting in low positioning accuracy and poor operational stability, this utility model aims to provide a telescopic device for automatic box packing machines with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a telescopic device for an automatic box packing machine, including a fixed plate and a telescopic mechanism mounted on the fixed plate. The telescopic mechanism includes a slide rail fixedly connected to the fixed plate, an adjusting plate slidably connected to the slide rail, and a drive assembly for driving the adjusting plate to reciprocate.

[0008] To achieve smooth and precise motion conversion, the drive assembly includes a cylinder, a connecting rod, a rotating shaft, and an annular frame. The output end of the cylinder is rotatably connected to one end of the connecting rod, while the other end of the connecting rod is rotatably connected to the rotating shaft. The annular frame is fixedly connected to the bottom surface of the adjusting plate. The rotating shaft is slidably and rotatably housed within the annular frame. This series of transmission combinations allows the rotational motion output by the cylinder to drive the annular frame housing the rotating shaft and the adjusting plate fixed thereto through the connecting rod and the rotating shaft, ultimately achieving smooth and precise linear reciprocating motion.

[0009] Preferably, limiting plates are symmetrically fixedly connected to both sides of the bottom of the adjusting plate. This symmetrical structure allows the two limiting plates to apply a uniform force to the box when the telescopic device extends, thereby stably clamping or limiting the box and effectively preventing the box from tilting during processing.

[0010] Preferably, the telescopic mechanism also includes a spring, with both ends of the spring fixedly connected between the adjusting plate and the fixed plate. The spring is stretched when the adjusting plate extends and resets when it retracts, providing effective buffering at the end of the reciprocating motion stroke, significantly reducing mechanical impact, protecting the equipment and reducing operating noise.

[0011] Preferably, the device also includes a controller, and a data hole is provided on the adjustment plate for the position sensor to detect. The controller is electrically connected to the cylinder and the position sensor respectively. The position sensor continuously monitors the position of the data hole to obtain the real-time extension and retraction position signal of the adjustment plate, and accurately controls the action of the cylinder based on this signal, thereby forming a complete closed-loop control system, which greatly improves the positioning accuracy and automation level.

[0012] Preferably, the cylinder is a 180-degree rotary cylinder. This type of cylinder can achieve precise rotational positioning at a fixed angle. Its high repeatability ensures that the starting and ending positions of the adjustment plate are highly consistent for each extension and retraction stroke, which is crucial for ensuring the stability of automated packing operations.

[0013] Preferably, a support frame is fixedly connected to the top side of the fixed plate. The support frame not only provides additional structural support for the entire telescopic mechanism, increasing the overall rigidity and stability of the device, but also provides an installation platform for other possible auxiliary components, enhancing the connection strength and expandability of the device.

[0014] Preferably, as a specific structure of the drive component, the other end of the connecting rod is rotatably connected to the middle of the rotating shaft. Setting the connection point in the middle of the rotating shaft helps to evenly transmit the driving torque generated by the cylinder to the rotating shaft, avoids the generation of eccentric torque, and makes the transmission smoother and more stable.

[0015] In a further preferred embodiment, the two ends of the rotating shaft can rotatably abut and slide against the two opposite inner walls of the annular frame. This engagement provides a clear guiding path for the rotating shaft. When the connecting rod drives the rotating shaft, the two ends of the rotating shaft are constrained by the inner walls of the annular frame, thereby ensuring that the rotating shaft can only drive the annular frame to perform purely linear motion along the direction of the slide rail. This is the key structural guarantee for achieving precise conversion from rotation to linear motion.

[0016] This utility model has the following beneficial effects: 1. This utility model solves the problem of complex drive structure or unstable transmission in existing telescopic devices by setting a drive assembly ingeniously combined with a rotary cylinder, connecting rod, rotating shaft and annular frame. It achieves the technical effect of smoothly and accurately converting rotary motion into linear telescopic motion, with a compact structure and reliable transmission.

[0017] 2. This utility model solves the problem of rigid impact, vibration and wear caused by traditional pneumatic telescopic devices at the end of the stroke by setting a spring between the adjusting plate and the fixed plate. It achieves the technical effect of bidirectional buffering of the telescopic and reset process, reducing mechanical impact, and improving the stability of device operation and service life.

[0018] 3. This utility model solves the problems of fixed telescopic distance, low positioning accuracy, and difficulty in adapting to different working conditions of traditional telescopic devices by opening data holes on the adjustment plate and cooperating with the controller for closed-loop control. It achieves precise control and real-time feedback of the telescopic stroke, ensuring the accuracy and repeatability of the box positioning, and improving the automation level and stability of the entire production line.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example

[0022] Please refer to Figures 1 to 4 This utility model provides a telescopic device for an automatic box packing machine, which aims to solve the problems of existing telescopic devices having impact during the telescopic process, low positioning accuracy, or lack of buffering mechanism.

[0023] like Figure 1 and Figure 2 As shown, the telescopic device for an automatic box packing machine includes a fixed plate 1 and a telescopic mechanism 2 mounted on the fixed plate 1. The fixed plate 1 serves as the mounting base for the entire device. The telescopic mechanism 2 is used to limit and push the box. Specifically, the telescopic mechanism 2 includes a slide rail 201 fixedly connected to the fixed plate 1, an adjusting plate 202 slidably connected to the slide rail 201, and a drive assembly 206 that drives the adjusting plate 202 to reciprocate along the length of the slide rail 201. The drive assembly 206 realizes the telescopic action, and its ingenious structure stably converts rotational motion into linear motion. The motion drive assembly 206 includes a cylinder 2061, a connecting rod 2062, a rotating shaft 2063, and an annular frame 2064. The output end of the cylinder 2061 is rotatably connected to one end of the connecting rod 2062, and the other end of the connecting rod 2062 is rotatably connected to the rotating shaft 2063. The annular frame 2064 is fixedly connected to the bottom surface of the adjusting plate 202, and the rotating shaft 2063 is slidably and rotatably housed within the annular frame 2064. Through this series of transmission connections, the rotational motion generated by the cylinder 2061 can be precisely converted into the linear reciprocating motion of the adjusting plate 202.

[0024] To ensure the stability and accuracy of the telescopic process, the technical solution of this embodiment also includes specific details regarding the auxiliary structure of the telescopic mechanism 2. Please refer to these details carefully. Figure 3 and Figure 4The following is a detailed description of these structures. Limiting plates 203 are symmetrically fixedly connected to both sides of the bottom of the adjusting plate 202. This symmetrical layout ensures that when the adjusting plate 202 extends, the two limiting plates 203 can apply force evenly to the housing, stabilizing the housing and preventing positional displacement during movement. To further improve the stability of the device's operation, a spring 205 is also connected between the adjusting plate 202 and the fixed plate 1. Specifically, the two ends of the spring 205 are fixedly connected to the adjusting plate 202 and the fixed plate 1, respectively. When the adjusting plate 202 extends, the spring 205 is stretched; when the adjusting plate 202 retracts, the spring 205 returns to its original position, thus providing force at both ends of the reciprocating motion. Effective buffering avoids rigid impact. To achieve precise control of the telescopic distance, the device also includes a controller 3, and a data hole 204 for position sensor detection is provided on the adjustment plate 202. The controller 3 is electrically connected to the cylinder 2061 and the position sensor respectively. By detecting the position of the data hole 204 in real time through the position sensor, the controller 3 can obtain the precise telescopic position signal of the adjustment plate 202 and control the start and stop of the cylinder 2061 accordingly, forming a closed-loop control system. In addition, a support frame 4 is fixedly connected to the top side of the fixed plate 1. The support frame 4 provides structural reinforcement and support for the entire telescopic mechanism 2, increasing the overall rigidity and connection strength of the device.

[0025] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, to achieve high-precision reciprocating positioning, the cylinder 2061 is specifically a 180-degree rotary cylinder 2061. This type of cylinder 2061 can stably achieve a fixed 180-degree rotation, with accurate and highly repeatable angular positioning, meeting the strict requirements for the extension and retraction start and stop positions in automated production scenarios, thereby ensuring the consistency of the extension and retraction stroke of the adjusting plate 202 each time. As a further optimization of the internal structure of the drive component 206, the other end of the connecting rod 2062 is rotatably connected to the middle of the rotating shaft 2063 to ensure that the driving torque is transmitted to the rotating shaft 2063 in a balanced manner. At the same time, the two ends of the rotating shaft 2063 can rotatably abut against and slide on the two opposite inner walls of the annular frame 2064. This structure makes the two ends of the rotating shaft 2063 guided and constrained by the inner wall of the annular frame 2064 when the connecting rod 2062 swings, forcing it to only drive the annular frame 2064 to move linearly along the direction of the slide rail 201, thereby achieving a smooth transition from rotation to linear motion.

[0026] Working principle: A telescopic mechanism 2 is installed on the top of the fixed plate 1 to facilitate the reciprocating telescopic process for automatic packing. The adjusting plate 202 moves back and forth on the slide rail 201, reducing structural friction. The cylinder 2061 in the drive assembly 206 drives the connecting rod 2062 to rotate. The connecting rod 2062 is rotatably connected to the rotating shaft 2063, causing the rotating shaft 2063 to rotate inside the annular frame 2064. Through the transmission of the cylinder 2061, the adjusting plate 202 is moved horizontally, utilizing the rotating shaft 206... 3. Adjustment of the ring frame 2064: The adjusting plate 202 extends along the slide rail 201 towards the box body, stretching the spring 205 at the left end of the adjusting plate 202 to achieve the adjustment function of the buffer stretching band. As the adjusting plate 202 extends, the limiting plates 203 on the left and right sides at its bottom gradually approach the box body to be installed, stably clamping the box body. The limiting plates 203, through symmetrical design, ensure that the box body is evenly stressed during clamping, avoiding positional displacement. The extension distance of the adjusting plate 202 is reflected to the controller 3 through data hole 204. To ensure the telescopic range meets the packing position requirements, cylinder 2061 stops rotating when it reaches the working area. The support frame 4 on the top side of the fixed plate 1 not only provides a limit for the box but also facilitates estimation of the mechanism and components, increasing connection strength. Cylinder 2061 is a 180-degree rotating cylinder 2061 with precise angle positioning and high repeatability, capable of stably achieving a fixed 180-degree angle rotation, meeting the requirements for rotation position in automated scenarios. It can be paired with controller 3 for real-time rotation control, improving the stability of the entire production line. The connecting rod 2062 and rotating shaft 2063 drive the adjusting plate 202 to move in the opposite direction along the slide rail 201. The stretched spring 205 acts as a buffer, preventing severe impact when the adjusting plate 202 resets, and the adjusting plate 202 returns to its initial position. Controller 3 controls the equipment, starting cylinder 2061 and drive component 206 to control the telescopic action and speed of the structure, controlling the timing and telescopic distance of the scissor-type telescopic device, achieving repetitive and stable packing operations, avoiding the tediousness of manual operation.
