It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0028] like Figures 1 to 3 As shown, this utility model provides a packaging lifting device. The packaging lifting device includes: a frame 1, a first conveying assembly 2, a second conveying assembly 3, an emergency passage 4, and two blocking mechanisms 5.
[0029] Specifically, the first conveying component 2 and the second conveying component 3 are both mounted on the frame 1, and the conveying directions of the first conveying component 2 and the second conveying component 3 are perpendicular to each other. An emergency channel 4 and the second conveying component 3 are respectively located on both sides of the first conveying component 2, with the emergency channel 4 directly opposite the second conveying component 3. Two blocking mechanisms 5 are respectively located on both sides of the emergency channel 4, and the blocking mechanisms 5 are slidably mounted on the frame 1. The blocking mechanisms 5 are used to block the cigarette packs 6 conveyed by the first conveying component 2, allowing the cigarette packs 6 to fall into the first conveying component 2. Compared to the prior art, this packaging lifting device is equipped with an emergency channel 4. When the downstream equipment malfunctions and stops, the two blocking mechanisms 5 move to open the emergency channel 4, allowing the cigarette packs 6 to be conveyed from the second conveying component 3 to the emergency channel 4, promptly discharging the cigarette packs 6, preventing their accumulation, and avoiding damage to the cigarette packs and blockage of the production line.
[0030] Optionally, the blocking mechanism 5 includes a driving member 51, a connecting member 52, and several blocking members 53. The driving member 51 is mounted on the frame 1, and the connecting member 52 is connected to the driving member 51 in a transmission manner. The driving member 51 can drive the connecting member 52 to move along the conveying direction of the first conveying assembly 2. Several blocking members 53 are spaced apart on the connecting member 52 along the conveying direction of the first conveying assembly 2. Specifically, when the cigarette pack 6 is being conveyed normally, the driving member 51 drives the two connecting members 52 to move closer to each other, causing the several blocking members 53 to close the emergency passage 4. The cigarette pack 6 changes from being conveyed laterally to being conveyed longitudinally by impacting the blocking members 53. When the cigarette pack 6 needs to be conveyed in an emergency, the driving member 51 drives the two connecting members 52 to move away from each other, the emergency passage 4 opens, and the cigarette pack 6 slides into the slide groove for storage through the emergency passage 4.
[0031] Optionally, the blocking mechanism 5 further includes a push rod 54, with both ends of the push rod 54 connected to the driving component 51 and the connecting component 52, respectively; the driving component 51 is a cylinder. Specifically, the driving component 51 is a dual-axis cylinder, mounted on the frame 1. The blocking mechanism 5 is provided with two push rods 54. The driving component 51, the push rods 54, and the connecting component 52 are fixed together, causing the push rods 54 to output linear motion and improving the stability of the connecting component 52. Further, the dual-axis cylinder is model CXSM20-80, with a cylinder diameter of 20mm and a stroke of 80mm.
[0032] Optionally, the connector 52 is made of aluminum alloy. Specifically, the connector 52 is made of high-strength aluminum alloy, with a total weight of only 0.4 kg. Through optimized structural design, it achieves high rigidity and low weight, significantly reducing motion inertia, which helps to improve response speed and reduce the load on the drive component 51.
[0033] Optionally, the blocking mechanism 5 further includes a plurality of rotating shafts 55, each corresponding to a plurality of blocking elements 53. The rotating shafts 55 are spaced apart on the connecting member 52 along the conveying direction of the first conveying assembly 2. The blocking elements 53 are rotatably sleeved on the rotating shafts 55, allowing the cigarette 6 to abut against the side wall of the blocking element 53. Specifically, in this embodiment, the blocking mechanism 5 is provided with three rotating shafts 55, which are fixed to the frame 1. The blocking elements 53 are mounted on the rotating shafts 55 via bearings, which can reduce the frictional force of the rotating blocking elements 53. Simultaneously, the three rollers are independently installed and can be individually disassembled and replaced, facilitating maintenance. Of course, in some other embodiments, the number of rotating shafts 55 is determined according to the actual situation, which will not be elaborated here. Further, the blocking element 53 is a roller.
[0034] Optionally, the blocking mechanism 5 also includes several wear-resistant parts, each corresponding to one of the blocking parts 53, with the wear-resistant parts disposed on the outer periphery of the blocking parts 53. Specifically, the wear-resistant parts are made of wear-resistant polymer materials, possessing a low coefficient of friction and high wear resistance, effectively guiding the cigarette packs 6 while minimizing wear on the cigarette pack packaging; simultaneously, they provide smooth guidance and reliable blocking, extending service life and reducing maintenance downtime due to wear. Further, the wear-resistant parts are made of polyethylene.
[0035] Optionally, the packaging lifting device also includes a solenoid valve, which is connected to two blocking mechanisms 5. Specifically, the packaging lifting device also includes a sensor and a controller. The sensor is installed on the downstream packaging machine or conveying equipment to monitor the operating status of the downstream packaging machine or conveying equipment in real time. The controller is communicatively connected to both the sensor and the solenoid valve. The controller can receive sensor signals, perform logical judgments, and issue commands to the solenoid valve to precisely control the on / off and direction of compressed air to the two cylinders, ensuring precise synchronization of the actions of the two cylinders and ensuring synchronous extension and retraction of the blocking parts 53 on both sides. This avoids jamming or skew, which could lead to poor conveying of the cigarette pack 6 or damage to the device, achieving reliable blocking and rapid emergency response. At the same time, the controller synchronously controls the two cylinders to ensure that the pneumatic signals, pressure, flow rate, and timing received by the two cylinders are highly consistent. In this embodiment, the controller can be a centralized or distributed controller. For example, the controller can be a single microcontroller or a combination of multiple distributed microcontrollers. The microcontroller can run a control program to control each component to achieve its function.
[0036] Optionally, the packaging lifting device also includes a position sensor, which is installed on the cylinder or the connector 52 to monitor the actual position of the blocking member 53 in real time. The controller compares the target position issued by the command with the actual position fed back by the position sensor in real time. If the two are inconsistent and exceed the allowable tolerance or time window, an alarm is triggered and a safety strategy may be implemented, such as locking the cylinder or trying to move again. This verification mechanism effectively prevents the baffle from opening or closing abnormally due to solenoid valve failure, air pipe leakage, mechanical jamming, etc., ensuring that it only moves when needed.
[0037] Optionally, the packaging lifting device also includes a detection unit. This unit not only monitors the equipment's start-up and shutdown but also identifies specific abnormal states of the cigarette packs 6. Feedback control is implemented via a computer, which can record events, statistically analyze efficiency, perform remote monitoring, and provide data support for possible predictive maintenance. Furthermore, the detection unit integrates high-speed sensors and real-time control algorithms to optimize the gas and electrical response times of the control system. The goal is to ensure that the time from detecting a shutdown or abnormal signal to the complete opening of the blocking element 53 (emergency position) is ≤0.5 seconds, thus minimizing the accumulation of cigarette packs 6.
[0038] This utility model provides a packaging lifting device. When downstream equipment experiences a planned shutdown, a brief malfunction, or the detection unit detects an abnormal state of the cigarette pack 6, such as blockage, tilting, or incorrect packaging, the signal is immediately fed back to the controller. The controller instantly issues a command to drive the solenoid valve, with a target response time ≤ 0.5 seconds. The solenoid valve switches the air path, and the drive component 51 drives the device to move. The push rod 54, through the connecting component 52, drives the blocking component 53 to move as a whole, causing the push rod 54 to extend or retract. The specific usage process is as follows:
[0039] Normal conveying state: Push rod 54 is fully extended and held, maintained by solenoid valve or continuous air supply; three blocking parts 53 are in the interception position, blocking the conveying path of cigarette strips 6 laterally; cigarette strips 6 from upstream move along the transverse conveyor belt and collide with blocking parts 53. The low friction characteristics of blocking parts 53 allow cigarette strips 6 to smoothly change their direction of movement, changing from transverse conveying to longitudinal conveying, and enter the lifting process.
[0040] Emergency handling status: When the downstream machine stops or an abnormal cigarette bar 6 is detected, the controller controls the solenoid valve to switch, and the cylinder push rod 54 quickly retracts; the three blocking parts 53 retract to the side, and at the same time the lifting belt stops moving, completely avoiding the lateral conveying path of the cigarette bar 6; the cigarette bar 6 is no longer blocked by the blocking parts 53, and under the inertia of the second conveying component 3 or the push of the subsequent cigarette bars 6, it slides directly into the preset sliding groove through the emergency channel 4, avoiding the accumulation and crushing damage of the cigarette bar 6 at the elevator inlet.
[0041] Furthermore, the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the protection scope of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
