Description

Technical Field

[0001] This utility model relates to the field of material transport equipment technology, specifically to a reversing conveyor device for a cigarette packaging machine. Background Technology

[0002] In the tobacco packaging and processing industry, conveyor belts are the core equipment for achieving continuous transfer of tobacco boxes, and their layout directly affects production efficiency and product quality. In actual production, due to limited workshop space or overall equipment layout planning constraints, it is often necessary to transfer tobacco boxes from longitudinal conveyor belts to transverse conveyor belts to complete subsequent packaging, sorting, and other processes.

[0003] In traditional production technology, the reversing conveyor of tobacco boxes often uses a direct transfer method, where the tobacco boxes are discharged from the unloading end of the longitudinal conveyor belt and fall freely to the feeding end of the transverse conveyor belt. However, in some scenarios, there is a height difference between the longitudinal and transverse conveyor belts. During free fall, the tobacco boxes gain a certain falling speed, and when they impact the surface of the transverse conveyor belt, a significant impact force is generated. Since the cigarettes inside the boxes are fragile, this impact force can cause damage such as compression deformation and cigarette breakage, reducing the product qualification rate. Therefore, we propose a reversing conveyor device for cigarette packaging machines to solve these problems. Utility Model Content

A strip-shaped hole is formed in the middle of one side of the guide frame. A sliding plate is slidably connected inside the strip-shaped hole. A triangular slider is slidably connected inside the guide frame. One end of the sliding plate inside the guide frame is connected to the triangular slider. A rectangular channel is formed at the bottom of one side of the guide frame. A transverse conveyor belt is disposed at the bottom of one side of the guide frame, and the feed end of the transverse conveyor belt is connected to the bottom of the rectangular channel; A longitudinal conveyor belt is disposed above one side of the guide frame. The longitudinal conveyor belt is perpendicular to the transverse conveyor belt and is used to convey materials to the upper port of the guide frame. A lifting assembly is disposed on the side of the guide frame, and the lifting assembly is used to drive the slide plate to move up and down along the strip hole.

[0005] Furthermore, the lifting assembly includes a support plate fixed to the bottom of one side of the guide frame, support plates fixed to the top two sides of the support plate, a top plate fixed to the top of the support plate, a guide rod spaced between the top plate and the support plate, a lifting plate slidably sleeved on the surface of the guide rod, one end of the lifting plate being connected to the slide plate, and a driving component being provided between the two support plates, the driving component being used to drive the lifting assembly to move up and down along the guide rod.

The output shaft of the servo motor is connected to the central shaft of the driving pulley via a coupling.

[0007] Furthermore, a rectangular notch is constructed above one side of the guide frame, and the unloading end of the longitudinal conveyor belt is connected to the rectangular notch.

[0013] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0014] This application provides a reversing conveyor device for a cigarette packaging machine, mainly to solve the problem that in the existing technology, there is a height difference between the longitudinal and transverse conveyor belts. During free fall, the tobacco box will have a certain falling speed, and when it impacts the surface of the transverse conveyor belt, it is prone to generating a large impact force. The cigarettes loaded inside the tobacco box are fragile items, and the impact force can cause damage such as squeezing and deformation, and cigarette breakage. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-4 Please provide a detailed explanation: A reversing conveyor device for a cigarette packaging machine, comprising: Guide frame 1 is placed vertically. A strip hole 101 is constructed in the middle of one side of guide frame 1. A slide plate 2 is slidably connected inside the strip hole 101. A triangular slider 3 is slidably connected inside guide frame 1. One end of the slide plate 2 inside guide frame 1 is connected to the triangular slider 3. A rectangular channel 102 is constructed at the bottom of one side of guide frame 1. A transverse conveyor belt 4 is set at the bottom of one side of the guide frame 1, and the feed end of the transverse conveyor belt 4 is connected to the bottom of the rectangular channel 102; The longitudinal conveyor belt 5 is set above one side of the guide frame 1. The longitudinal conveyor belt 5 is perpendicular to the transverse conveyor belt 4 and is used to convey materials to the upper port of the guide frame 1. A lifting assembly 6 is disposed on the side of the guide frame 1. The lifting assembly 6 is used to drive the slide plate 2 to move up and down along the strip hole 101. The lifting assembly 6 includes a support plate 601 fixed to the bottom of one side of the guide frame 1. Support plates 602 are fixed on both sides of the top of the support plate 601. A top plate 603 is fixed on the top of the support plate 602. A guide rod 604 is spaced between the top plate 603 and the support plate 601. A lifting plate 605 is slidably sleeved on the surface of the guide rod 604. One end of the lifting plate 605 is connected to the slide plate 2. A support plate 605 is disposed between the two support plates 602. There is a driving component, which is used to drive the lifting component to move up and down along the guide rod 604. The driving component includes a drive pulley 606 rotatably connected between the upper sides of the two support plates 602, a driven pulley 607 rotatably connected between the bottom sides of the two support plates 602, and a transmission belt 608 drivingly connecting the drive pulley 606 and the driven pulley 607. A servo motor 609 is mounted on the upper side of the outer side of one of the support plates 602. The output shaft of the servo motor 609 is connected to the central shaft of the drive pulley 606 through a coupling.

[0015] Workflow Description Material conveying preparation: Start the device, and the servo motors 609 in the transverse conveyor belt 4, longitudinal conveyor belt 5 and lifting assembly 6 simultaneously enter the standby state. The triangular slider 3 is initially located in the guide frame 1 at the highest position that matches the unloading height of the longitudinal conveyor belt 5, ensuring precise docking with the material conveying path.

[0016] Material Receiving and Transfer: After the material falls onto the inclined surface of the triangular slider 3, the servo motor 609 starts, and its output shaft drives the drive pulley 606 to rotate via a coupling. When the drive pulley 606 rotates, it drives the driven pulleys 607 on the bottom side of the two support plates 602 to rotate synchronously through the meshing transmission action of the transmission belt 608. As the transmission belt 608 circulates, the lifting plate 605, which is fixedly connected to it, slides vertically downward along the guide rod 604 between the top plate 603 and the support plate 601 (the guide rod 604 restricts the lifting plate 605 to move only in the vertical direction to avoid deviation). During the sliding process of the lifting plate 605, it further pulls the slide plate 2 connected to it to move synchronously downward within the strip hole 101 of the guide frame 1, and finally drives the triangular slider 3 to move smoothly downward inside the guide frame 1. When the triangular slider 3 moves downward to a position flush with the bottom rectangular channel 102 of the guide frame 1, the material slowly slides down along the inclined surface of the triangular slider 3 under the action of gravity. This process avoids the impact force generated by traditional free fall. The sliding material smoothly transitions to the feeding end of the transverse conveyor belt 4 through the rectangular channel 102, completing the reversal from longitudinal to transverse conveying. Finally, the transverse conveyor belt 4 transfers the material to subsequent packaging, sorting and other processes.

[0017] The device uses a lifting component 6 to move a triangular slider 3 along a guide frame 1, achieving a smooth displacement of the tobacco box from high to low, avoiding direct impact from falling. At the same time, relying on the inclined structure of the triangular slider 3, combined with the weight of the tobacco pack itself, it slides gently along the inclined slope towards the transverse conveyor belt 4. This avoids the problems of cigarette breakage and compression deformation caused by traditional free fall, and eliminates the need for additional power to drive material transfer. It balances buffer protection and efficient conveying, effectively improving the qualification rate and stability of tobacco box conveying.

[0018] like Figure 2 As shown, in some embodiments, a rectangular notch 103 is constructed above one side of the guide frame 1. The unloading end of the longitudinal conveyor belt 5 connects to the rectangular notch 103. More specifically, the rectangular notch 103 allows the tobacco box conveyed by the longitudinal conveyor belt 5 to smoothly enter the guide frame 1, avoiding material deviation, jamming, or falling during material conveying. This design eliminates the connection gap between the longitudinal conveyor belt 5 and the guide frame 1, ensuring a smooth transition of the tobacco box from longitudinal conveying to entering the guide frame 1. This lays the foundation for the subsequent triangular slider 3 to receive the material and achieve smooth reversal, improving the stability of the overall conveying process.

[0019] like Figure 4 As shown, in some embodiments, the three corners of the triangular slider 3 are rounded, and several balls are embedded on both sides of the triangular slider 3. The balls roll in contact with the inner wall of the guide frame 1. More specifically, the rounded corner design of the corners of the triangular slider 3 can avoid damage or jamming of the box caused by the collision between the tobacco box and the sharp corners of the slider, ensuring smooth material flow. The balls embedded on both sides roll in contact with the inner wall of the guide frame 1, converting the sliding friction when the slider moves into rolling friction, greatly reducing frictional resistance, reducing component wear and extending service life. At the same time, it makes the lifting component 6 drive the triangular slider 3 to move up and down more smoothly, indirectly ensuring the conveying stability of the tobacco box on the inclined surface of the slider, and further improving the reliability of the device operation.

[0020] like Figure 4 As shown, in some embodiments, the slope of the triangular slider 3 is 5-10 degrees. More specifically, a slope of 5-10 degrees will prevent the tobacco box from sliding down the slope too quickly due to excessive steepness, causing impact and preventing the cigarettes inside from breaking or deforming; nor will it cause the tobacco box to become stuck on the slope due to friction due to excessively gentle slope, resulting in conveying blockage. This slope allows the tobacco box to slide smoothly along the slope towards the transverse conveyor belt 4 at a steady speed using its own weight, achieving smooth transfer without additional power and ensuring the stability and safety of the material during reversing conveying.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
