AI Technical Summary
In existing cigarette pack rejection devices, cigarette packs are prone to getting stuck on the open side of the rejection plate, causing the rejection plate to be pressed open, which in turn leads to frequent equipment shutdowns and reduces cigarette production efficiency.
A guide component with an arc-shaped guide surface is used to guide the cigarette pack pushed by the cigarette pack pusher to the rejection plate, so that the cigarette pack continues to move forward under the action of inertia and gravity, avoiding jamming between the rejection chain and the rejection plate. The normal opening and closing of the rejection plate is ensured by setting avoidance gaps and magnetic suction components.
This effectively avoids cigarette pack jamming, reduces the downtime of the rejection chain, and improves cigarette production efficiency.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of tobacco processing equipment technology, and in particular to a tobacco pack rejection device. Background Technology
[0002] During the cigarette production and packaging process, defective cigarette packs are usually rejected by pushing them to the rejection port at the end of the cigarette pack guide rail using a cigarette pack pusher. The rejection port is equipped with a movable rejection plate. When a certain weight of cigarette packs accumulates on the rejection plate, the rejection plate can be opened, triggering a proximity switch to stop the conveyor equipment and cause the cigarette packs accumulated on the rejection plate to fall off.
[0003] However, in existing cigarette pack rejection devices, when the cigarette pack is moved by the cigarette pack pusher, it is easy for it to get stuck on the opening side of the rejection plate, causing the rejection plate to be pressed open, which in turn leads to frequent machine shutdowns and reduces cigarette production efficiency.
[0004] Therefore, there is an urgent need for a cigarette pack rejection device to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a cigarette pack rejection device to solve the technical problem in the prior art where, when cigarette packs are moved by the cigarette pack pusher, they are easily stuck on the opening side of the rejection plate, causing the rejection plate to be pressed open, which in turn leads to frequent machine shutdowns and reduces the efficiency of cigarette production.
[0006] To achieve this objective, the present invention adopts the following technical solution:
[0007] The cigarette pack rejection device includes:
[0008] frame;
[0009] The rejection assembly includes a rejection chain, cigarette pack pushers, and a rejection plate, wherein the rejection chain is mounted on the frame; and multiple cigarette pack pushers are arranged around the outer ring of the rejection chain.
[0010] The rejection plate is disposed on the frame and spaced apart from one end of the rejection chain;
[0011] A guide assembly is disposed on both sides of the rejection guide rail on the frame near the rejection plate. The guide assembly has an arc-shaped guide surface, and the cigarette pack pushed by the cigarette pack pusher is guided to the rejection plate through the arc-shaped guide surface.
[0012] Preferably, the rejection plate has an avoidance notch at one end near the rejection guide rail, through which the cigarette pack pusher can pass.
[0013] Preferably, the guiding assembly includes a fixed guide and a rotating guide. The fixed guide is disposed on both sides of the rejection guide rail on the frame near the rejection plate. The rotating guide is disposed on the rejection plate. The upper surfaces of the fixed guide and the upper surfaces of the rotating guide are located on the same arc surface and smoothly transition to form the arc-shaped guiding surface for guiding the cigarette pack.
[0014] Preferably, the lower surface of the fixed guide member can abut against the rejection plate.
[0015] Preferably, the end of the fixed guide member away from the rotating guide member is provided with a chamfer.
[0016] Preferably, a transition guide is also included, which is disposed at the end of the fixed guide away from the rotating guide, and the connection between the transition guide and the fixed guide is smoothly disposed.
[0017] Preferably, there are two rejection chains, and the guide assembly between the two rejection chains is integrally formed.
[0018] Preferably, the highest point of the cigarette pack pusher is higher than the highest point of the guide assembly.
[0019] Preferably, the rejection plate is a metal plate, and the frame is provided with a magnetic suction device that can fix the rejection plate.
[0020] Preferably, the guide component is a semi-circular arc structure with a radius of 90mm-110mm.
[0021] The beneficial effects of this utility model are:
[0022] The cigarette pack rejection device proposed in this utility model, by setting a guide component with an arc-shaped guide surface, guides the cigarette pack pushed by the cigarette pack pusher to the rejection plate. This allows the cigarette pack to continue moving forward under the guidance and support of the guide component when it is pushed to the end of the rejection chain, relying on inertia and gravity, instead of falling immediately. This avoids the cigarette pack getting stuck between the rejection chain and the rejection plate, which would cause the cigarette pack pusher to continuously push the cigarette pack and open the rejection plate, resulting in frequent shutdowns of the rejection chain, thus improving the efficiency of cigarette production.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. 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.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0033] like Figure 1As shown, this embodiment provides a cigarette pack rejection device, including a frame, a rejection assembly, and a guide assembly. The rejection assembly includes a rejection chain, cigarette pack pushers, and a rejection plate 1. The rejection chain is mounted on the frame. Multiple cigarette pack pushers are arranged around the outer ring of the rejection chain. The rejection plate 1 is mounted on the frame and spaced apart from one end of the rejection chain. The guide assembly is located on both sides of the rejection guide rail on the frame near the end of the rejection plate 1. The guide assembly has an arc-shaped guide surface, through which the cigarette packs pushed by the cigarette pack pushers are guided to the rejection plate 1.
[0034] It is understandable that the method of eliminating the chain drive is a conventional technical means in this field, and will not be elaborated here.
[0035] Of course, in some other embodiments, the removal chain can also be in the form of a conveyor belt.
[0036] The cigarette pack rejection device provided in this embodiment, by setting a guide component with an arc-shaped guide surface, guides the cigarette pack pushed by the cigarette pack pusher to the rejection plate 1. This allows the cigarette pack to continue moving forward under the guidance and support of the guide component when it is pushed to the end of the rejection chain, relying on inertia and gravity, instead of falling immediately. This avoids the cigarette pack getting stuck between the rejection chain and the rejection plate 1, which would cause the cigarette pack pusher to continuously push the cigarette pack and open the rejection plate 1. This avoids frequent shutdowns of the rejection chain and improves cigarette production efficiency.
[0037] Furthermore, such as Figure 1 As shown, in some embodiments, the rejection plate 1 has an avoidance notch at one end near the rejection guide rail, through which the cigarette pack pusher can pass.
[0038] Understandably, by setting a clearance notch on the rejection plate 1, it is possible to prevent the top of the cigarette pack pusher from hitting the rejection plate 1 as the cigarette pack pusher moves with the rejection chain, which would cause the rejection plate 1 to open and stop the rejection chain. This can significantly reduce the frequency of rejection chain stoppages and improve the production efficiency of cigarettes.
[0039] Furthermore, the highest point of the cigarette pack pusher is higher than the highest point of the guide assembly. Understandably, this arrangement ensures that the cigarette pack pusher can effectively push the cigarette pack along the guide assembly, ensuring that the cigarette pack continues to move forward to the rejection plate 1 under the guidance and support of the guide assembly, reducing the chain stop frequency and improving production efficiency.
[0040] Furthermore, in some embodiments, the guiding assembly includes a fixed guide 21 and a rotating guide 22. The fixed guide 21 is disposed on both sides of the rejection guide rail near the rejection plate 1 on the frame, and the rotating guide 22 is disposed on the rejection plate 1. The upper surfaces of the fixed guide 21 and the rotating guide 22 are located within the same arc surface and smoothly transition, together forming an arc-shaped guiding surface for guiding the cigarette packs. It can be understood that by disposing the rotating guide 22 on the rejection plate 1, and ensuring that the upper surfaces of the fixed guide 21 and the rotating guide 22 are flush and smoothly transition, the fixed guide 21 can better ensure that the cigarette packs move smoothly onto the rejection plate 1 under the guiding support of the guiding assembly, further reducing the frequency of rejection chain shutdowns and further improving the production efficiency of cigarettes.
[0041] Furthermore, in some embodiments, a chamfer is provided at the end of the fixed guide 21 away from the rotating guide 22 to further improve the smoothness of the cigarette pack passing through the guide assembly, ensuring that the cigarette pack moves smoothly onto the rejection plate 1.
[0042] Furthermore, in some embodiments, the lower surface of the fixed guide 21 can abut against the rejection plate 1. It is understood that when the weight of the cigarette packs piled on the rejection plate 1 exceeds the force required to keep the rejection plate 1 closed, the rejection plate 1 can open. When the cigarette packs fall off the rejection plate 1, the rejection plate 1 rotates back to the closed position. To prevent the rejection plate 1 from rotating excessively, the fixed guide 21 extends from the frame near one end of the rejection plate 1, allowing the rejection plate 1 to abut against the lower surface of the fixed guide 21, thereby limiting the rejection plate 1 and ensuring that the cigarette packs do not get stuck between the rejection plate 1 and the cigarette pack pusher due to excessive rotation of the rejection plate 1.
[0043] For example, in this embodiment, the rejection plate 1 is a metal plate, and a magnetic suction device is provided on the frame to fix the rejection plate 1. It is understood that the magnetic suction device is located on the lower surface of the fixed guide 21. When the weight of the cigarette pack on the rejection plate 1 exceeds the magnetic force exerted by the magnetic suction device on the rejection plate 1, the rejection plate 1 can rotate and open, allowing the cigarette pack to fall off. After the cigarette pack falls off, the rejection plate 1 is re-attracted to the lower surface of the fixed guide 21 by the magnetic force of the magnetic suction device, thus closing the rejection plate 1.
[0044] Furthermore, in some embodiments, the cigarette pack rejection device further includes a transition guide 23, which is disposed at the end of the fixed guide 21 away from the rotating guide 22, and the connection between the transition guide 23 and the fixed guide 21 is smoothly disposed.
[0045] Understandably, the smaller tilt angle of the transition guide 23 further reduces the jerking sensation of the cigarette pack as it passes through the guide assembly, reduces the loss of the cigarette pack's moving speed, and thus ensures that the cigarette pack moves to the rejection plate 1 at a sufficient speed. In some embodiments, the end of the transition guide 23 away from the fixed guide 21 is also provided with a chamfer.
[0046] Furthermore, the guide component is a semi-circular arc with a radius of 90mm-110mm.
[0047] Specifically, such as Figure 1 As shown, in this embodiment, two rejection chains are provided, and the guide assembly between the two rejection chains is integrally formed. This arrangement reduces the number of parts, facilitating manufacturing and reducing the number of installation steps. For ease of understanding, in this embodiment, the guide assembly is divided into a first guide block, an intermediate guide block, and a second guide block. The first guide block includes a first fixed guide block 211 and a first rotating guide block 221. The intermediate guide block includes an intermediate fixed guide block 212 and an intermediate rotating guide block 222. The second guide block includes a second fixed guide block 213 and a second rotating guide block 223. The first guide block is a semicircular arc with a radius of 90 mm. The second guide block is a semicircular arc with a radius of 80 mm. The third guide block is a semicircular arc with a radius of 110 mm.
[0048] More specifically, the first guide, the intermediate guide, and the second guide can be manufactured by machining as a single piece and then cutting it. This further ensures the smoothness of the upper surfaces of the fixed guide 21 and the rotating guide 22. If the radius of curvature of the guide assembly is too small, it will cause blockage of the rejection channel; conversely, if it is too large, the guide block will not provide support and will not be able to solve the jamming problem. The radius of curvature of the guide assembly is the optimal size obtained through experiments, which can ensure that it provides support for the cigarette pack without hindering the forward movement of the cigarette pack.
[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
