Description

Technical Field

[0001] This utility model relates to the field of tobacco processing equipment, and specifically to a straightening device for tobacco packs before slicing. Background Technology

[0002] The leaf-making section of the expanded tobacco processing line encompasses a series of equipment, including a slicer, a loosening and moistening machine, an on-site air classifier, a cleaning device, a vibrating conveyor, a belt conveyor, and a pre-mixing cabinet. These devices work together to ensure a complete leaf-making process from unpacking the tobacco bales to the pre-mixing cabinet. After the tobacco bales are unpacked, they are smoothly transported a long distance to the slicer by three conveyor belts. Once the bales reach the starting position of the slicer, the push-rod gate opens precisely at the slicing table and smoothly moves along both sides of the bales to their ends. If the tobacco bales tilt during transport, the push-rod gate may collide with the bales, triggering an alarm and causing the machine to stop.

[0003] To ensure the stability of tobacco bales during transport, existing technology installs a simple guide device made of stainless steel plate in front of the slicer. However, this simple guide device is ineffective at correcting layered or severely tilted tobacco bales, which can seriously affect the production efficiency of the leaf-cutting section. Utility Model Content

[0004] In view of the above-mentioned deficiencies or defects in the prior art, the present invention provides a straightening device for cigarette packs before slicing. This device can effectively straighten the unpacked cigarette packs, ensure the stable operation of the production line, and thus improve production efficiency.

[0017] The specific embodiments of this utility model are described in detail below. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0018] In this utility model, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the orientation in the assembled and used state. "Inner" and "outer" refer to the inner and outer sides relative to the outline of each component itself.

[0019] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of the utility model described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0020] like Figure 1 As shown, this utility model provides a straightening device for the pre-slicing tobacco pack, comprising a straightening unit and a frame 1. The straightening unit is disposed on both sides of the bearing surface of the conveying equipment, forming a straightening channel above the bearing surface. The straightening unit includes multiple rollers 3, which are spaced apart along the conveying direction and whose axes extend vertically. The frame 1 includes several first support members, several first fixing members, and several second fixing members. The first support members are fixedly disposed on the side of the straightening unit away from the straightening channel, and the straightening unit is fixedly connected to the conveying equipment through the first support members. The first fixing members are disposed at the lower end of the first support members, and the first support members are fixedly connected to the conveying equipment through the first fixing members. The straightening unit is also fixedly connected to the first support members through the second fixing members.

[0021] It should be noted that the conveying equipment refers to belt conveyors or chain conveyors commonly used in the prior art for conveying cigarette packs. These are devices known in this technical field, and this utility model does not claim protection for the structural innovation of the equipment itself.

[0022] By setting up a alignment unit composed of multiple rollers 3 above the conveying equipment, effective guidance and posture constraint are provided for the tobacco packages entering the alignment channel. As the tobacco packages pass through the alignment channel along the conveying direction, they are laterally restrained by the rollers 3 arranged on both sides, achieving alignment and posture adjustment. The rollers 3 are arranged vertically, providing guidance while effectively reducing frictional resistance with the sides of the tobacco packages, thus ensuring the stability and consistency of the tobacco package conveying process. The frame 1 provides structural support and overall fixation. In this way, effective alignment of the tobacco packages is achieved, significantly improving the neatness and positioning accuracy of the tobacco packages before slicing, which is beneficial for improving slicing quality and efficiency, thereby increasing production efficiency.

[0023] The number and spacing of the rollers 3 are determined according to the size of the cigarette pack to ensure the corrective effect. In one optional embodiment, the length of the rollers 3 arranged in a corrective unit is greater than the length of the cigarette pack. The gap between adjacent rollers 3 is less than one-fifth of the length of the cigarette pack.

[0024] The height of roller 3 can be selected according to the height of the cigarette pack. In a preferred embodiment, the length of roller 3 is greater than or equal to the height of the cigarette pack, so as to simultaneously straighten the top and bottom of the cigarette pack. During the conveying process, the cigarette pack may separate or tilt. The length of roller 3 is configured to cover the entire height of the cigarette pack, which can achieve overall straightening of the cigarette pack and solve the problems of separation and tilting.

[0025] The tobacco pack inlet end of the correction channel is provided with a guide plate 7, and the guide plates 7 arranged on both sides of the inlet end form a guide opening that gradually narrows along the tobacco pack conveying direction. The frame 1 is used to install and fix the correction unit and the guide plates 7.

[0026] The guide plate 7 guides the tobacco packages as they enter the straightening channel, adjusting their posture in advance, reducing the straightening pressure on the rollers, and improving the overall efficiency and accuracy of the straightening device. Simultaneously, the inclined guide plate 7 effectively buffers the impact when the tobacco packages enter the straightening channel, helping to improve conveying stability, reduce the risk of package bouncing or collision, and thus improve the integrity rate and processing consistency of the tobacco packages.

[0027] Furthermore, the guide slope of the guide plate 7 does not protrude spatially from the guide side formed by the plurality of rollers 3.

[0028] The above technical solution actually provides two specific implementation methods.

[0029] Specific Implementation Method 1: The guiding slope of the guide plate 7 smoothly connects with the guiding side. This is a preferred implementation method, achieving a smooth transition without interference. If the guide plate 7 protrudes from the guiding side, that is, the end of the guide plate 7 is located between the left and right guiding sides, meaning the width of the narrow opening formed by the two guide plates 7 is less than the width between the two guiding sides, in this implementation method, the tobacco pack may not have another opportunity to contact the roller 3 after entering the straightening channel, thus reducing the straightening effect.

[0030] Specific Implementation Method Two: The guiding slope and guiding side of the guide plate 7 are misaligned, meaning the width of the narrow opening formed by the two guide plates 7 is slightly larger than the width between the two guiding side surfaces. This arrangement allows for the alignment of the cigarette pack. After the cigarette pack is initially aligned by the guide plate 7, it enters the alignment channel and contacts the roller 3 for further, more precise alignment. However, this implementation method has certain drawbacks: the roller 3 closest to the guide plate 7 becomes a "hard point" of contact with the cigarette pack. When the cigarette pack hits this protruding edge during high-speed conveying, it is prone to jamming, collision, or friction, which may exacerbate the tilting of the cigarette pack or damage it.

[0031] The correction unit also includes a side plate 4 fixedly connected to the frame 1. The roller 3 is rotatably mounted on the side plate 4. At least two light-transmitting frames are spaced apart on the side plate 4 along the extension direction of the correction channel. The light-transmitting frames on the side plates 4 on both sides of the correction channel are arranged opposite each other. The light-transmitting frames cover at least one gap formed between adjacent rollers 3.

[0032] The light-transmitting frame provides a detection window for the photoelectric detection device, ensuring that light can penetrate the side panel area to detect the position or state of the cigarette pack. A light-transmitting plate 6 can be installed at the light-transmitting frame to prevent dust and tobacco debris from entering the detection area. The light-transmitting plate 6 can be made of polycarbonate, acrylic, or tempered glass. The connection between the light-transmitting plate 6 and the light-transmitting frame can be by bolts, clips, or adhesive.

[0033] like Figure 1 As shown, the side plate 4 is fixedly connected to the frame 1 via a triangular truss structure 5 to enhance the connection stability between the side plate 4 and the frame 1. The side plate 4 is fixedly connected to the frame 1. Figure 2 and Figure 3As shown, the side plate 4 has a plate-like structure and extends along the length of the alignment channel. It includes a main body 301, mounting plates arranged along the upper and lower sides of the main body 301, and a connecting plate 305 disposed in the middle area of ​​one side of the main body 301. Both the mounting plates and the connecting plate 305 extend along the length of the side plate 4. The upper and lower mounting plates are arranged opposite each other and have multiple first mounting holes 302 and second mounting holes 303 along the length of the mounting plates. The first mounting holes 302 are used to install the roller 3, and the second mounting holes 303 are used to install the guide plate 7. The connecting plate 305 has a first through hole 306. The first through hole 306, together with the triangular truss structure 5, enables the side plate 4 to be fixedly connected to the frame 1.

[0034] like Figure 3 As shown, a third mounting hole 304 is provided around the light-transmitting frame on the main body 301 for mounting the light-transmitting plate 6.

[0035] like Figure 1 As shown, one side plate 4 is fixedly connected to the frame 1 through the connecting plate 305 and the triangular truss structure 5, and the other side is fixedly connected to the top through the bracket 2 located on top of it.

[0036] The frame 1 is a through-type frame with openings at both ends. The alignment channel passes through the interior of the frame, and the alignment unit is fixedly installed on the inner side wall of the frame. The legs of the frame 1 are equipped with mounting bases 8, which are used to mount and fix the frame 1 to the conveying equipment. Figure 4 As shown, a fourth mounting hole 801 is provided around the periphery of the mounting base 8, and the mounting base 8 is fixedly connected to the legs of the frame 1 through the fourth mounting hole 801.

[0037] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0038] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0039] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
