Abstract
Description
Technical Field
[0001] This invention relates to the field of cigarette manufacturing technology, and in particular to an automatic guide and separation device for rejecting waste from a cigarette forming machine. Background Technology
[0002] The YJ118 cigarette forming machine is a core piece of equipment in cigarette production. When the machine starts, before the cigarette pack enters the cigarette conveying device, the starting end of the cigarette pack is monitored in real time by the S21S photoelectric switch. When the cigarette pack signal is detected, the signal is fed back to the rejection program set in the system, and the air path of the solenoid valve installed on the cigarette conveying guide rail is opened to pre-reject the first 5 cigarettes (the default is 5, which can be adjusted in the HMI parameters) with double the length, including the short cigarettes produced by the cutting process of the cutter head at the very front of the cigarette pack.
[0003] In existing technology, the YJ118 cigarette rolling machine has two inclined sliding plates, one facing inward and the other outward, mounted on the frame below the cigarette conveying device. The inward-facing sliding plate guides double-length cigarettes falling from the cigarette conveying device into the waste tobacco belt of the YJ218 filter loading machine. However, when the cigarette pack starts moving, short-headed and double-length cigarettes removed from the cigarette conveying guide rail only fall onto the sliding plate facing outward, and then into the cigarette pack collection bin. According to process quality requirements, the cigarette pack tobacco in the collection bin can be returned to the tobacco storage area of the tobacco supply system. Therefore, it is necessary to accurately sort the short-headed, double-length, and tobacco tobacco in the cigarette pack collection bin manually. Double-length cigarettes are relatively easy to manually sort and remove from the tobacco tobacco. However, sorting short-headed cigarettes from the tobacco is a very time-consuming and labor-intensive task. To prevent short-headed cigarettes from being mixed with recycled tobacco and causing product quality incidents, operators must manually sort out the short-headed cigarettes one by one from the cigarette pack collection bin. This not only significantly increases the intensity of manual labor, but also carries the risk of incomplete sorting, with short-headed cigarettes still potentially mixed in with normal tobacco, seriously affecting the stability of cigarette product quality. Furthermore, the time-consuming manual sorting process reduces the overall operating efficiency of the cigarette making unit.
[0004] In summary, the existing waste removal and smoke guiding structure of the YJ118 cigarette rolling machine cannot achieve automatic guidance and separation of short-headed cigarettes, resulting in defects such as significant quality risks, high labor costs, and low equipment operating efficiency. There is an urgent need to optimize and improve the waste removal and smoke guiding plate structure to solve the technical problems of automatic separation of short-headed cigarettes and elimination of the drawbacks of manual sorting. Summary of the Invention
[0005] This invention addresses the shortcomings of existing technologies by developing an automatic guide and separation device for rejecting waste cigarettes in a cigarette rolling machine. By optimizing the structure of the cigarette guiding device, this invention enables both rejected short-headed cigarettes and double-length cigarettes to be automatically guided and slide down to the waste cigarette belt, achieving automatic separation of rejected cigarettes from stale tobacco. In particular, it completely diverts short-headed cigarettes, which are the most time-consuming and labor-intensive to sort manually, eliminating the need for manual sorting, significantly reducing labor intensity, eliminating potential quality problems, and making the device easy to assemble and disassemble with high maintenance efficiency.
[0006] The technical solution of this invention to solve the technical problem is as follows:
[0007] This application provides an automatic guide and separation device for rejecting waste from a roll forming machine, including... A fixing plate is vertically installed and has fixing holes for fixing the entire device to the frame of the rolling forming machine; A support plate, the bottom of which is fixedly connected to the top of the fixing plate, the support plate being inclined outward and its upper surface facing inward. A limiting plate is vertically installed, and its bottom end is fixedly connected to the top end of the support plate; A sliding plate is fixedly connected to the upper inner side of the support plate. The sliding plate is inclined and the angle between the sliding plate and the vertical plane is greater than the angle between the support plate and the vertical plane. The lower end of the sliding plate extends above the waste smoke belt of the rolling forming machine. The blocking plate is fixedly connected to the inner front end of the support plate and the limiting plate, and is at the same height as the support plate and the limiting plate, and is located in front of the slide plate.
[0008] As an improvement to the above solution, the surface of the support plate is inclined outward relative to the vertical plane where the fixing plate is located, with an inclination angle of 40°.
[0009] As an improvement to the above solution, the surface of the slide plate is inclined relative to the vertical plane where the fixed plate is located, and the upper end of the slide plate faces the inside of the rolling forming machine, with an inclination angle of 50°.
[0010] As an improvement to the above solution, the fixing plate is fixed to the frame of the rolling and forming machine by the cooperation structure of the external thread set screw and the hand-tightening nut.
[0011] As an improvement to the above solution, the support plate and the fixing plate are welded together to form an integral structure; one side of the slide plate is fixed to the support plate by welding; the limiting plate is fixedly connected to the top of the support plate by welding; the height and width of the blocking plate cover the splash range when the cigarette falls; the blocking plate, the upper part of the support plate and the limiting plate work together to form a physical barrier.
[0012] Compared with existing technologies, the above solution has the following advantages or beneficial effects: 1. This invention optimizes the structure of the smoke guiding device, enabling both rejected short-headed cigarettes and double-length cigarettes to automatically slide down into the waste cigarette belt, achieving automatic separation of rejected cigarettes from the shredded tobacco. In particular, it completely diverts short-headed cigarettes that were originally mixed in with the tobacco and were extremely difficult to sort manually, completely eliminating the process of manually sorting short cigarettes from the shredded tobacco collection bin. The sorting time per machine is reduced from more than 20 minutes to zero, significantly reducing labor intensity and fundamentally avoiding the quality risks caused by incomplete manual sorting.
[0013] 2. The present invention provides a vertical limiting plate at the top of the support plate and fixes the blocking plate to the inner front end of the support plate and the limiting plate at the same height as both, which further improves the overall protection height of the device, enhances the structural stability of the blocking plate, effectively prevents cigarettes from jumping over the blocking plate and splashing to the outside during high-speed removal, and improves the reliability of cigarette guiding and separation.
[0014] 3. The smoke guide plate of the present invention adopts a tool-free installation structure with external thread set screw and external knurled step hand-tightening nut. No special tools are required for disassembly and adjustment, making the operation simple and quick, effectively improving equipment maintenance efficiency, reducing downtime, and ensuring continuous and stable operation of the unit.
[0015] 4. This invention has a compact structure and strong size adaptability, and can be directly installed and used on the existing ZJ118 coil forming machine. It has outstanding versatility and economy, and is easy to promote and apply in batches in the same type of coiling unit, thereby comprehensively improving the operating efficiency and production management level of the coiling production line.

[0023] Example This embodiment provides an automatic guide and separation device for rejecting waste cigarettes in a cigarette rolling machine. The device is installed below the smoke conveying guide rail of the ZJ118 cigarette rolling machine, corresponding to the area above the waste smoke belt, and is used to receive and guide the rejected short-headed cigarettes and double-length cigarettes.
[0024] See Figures 1 to 4 The waste removal and smoke guiding device includes a fixed plate 1, a support plate 2, a sliding plate 3, a blocking plate 4, and a limiting plate 5, all made of 304 stainless steel. Based on precise measurements of the space and positioning dimensions of the protective cover below the smoke guiding rail, the overall height of the device is preferably designed to be 335mm, and the width is preferably designed to be 128mm. Its compact structure allows it to be directly adapted to the installation space of existing ZJ118 rolling forming machines.
[0025] The fixing plate 1 is the foundation component for the entire waste removal and smoke guiding device. The fixing plate 1 is a vertically oriented plate with at least one fixing hole 11 on its surface. The fixing plate 1 is fixed to the frame of the ZJ118 rolling and forming machine via a combination of an external threaded set screw and a hand-tightening nut. Specifically, one end of the external threaded set screw is pre-fixed to the frame of the rolling and forming machine, the fixing hole 11 of the fixing plate 1 passes through the external threaded set screw, and is then tightened by screwing in the externally knurled step hand-tightening nut, thereby pressing the fixing plate 1 firmly against the frame surface. This tool-free connection structure allows operators to quickly install, disassemble, and fine-tune the smoke guiding device by hand without the need for a special wrench.
[0026] The support plate 2, serving as the main load-bearing frame, is fixedly connected at its bottom to the top of the fixed plate 1. As a preferred connection method, the support plate 2 and the fixed plate 1 are welded together to form an integral structure. The support plate 2 is inclined outwards, meaning its surface is tilted outwards relative to the vertical plane containing the fixed plate 1; specifically, this tilt angle is 40°. The support plate 2 extends outwards from the rolling forming machine, providing stable mounting support for components such as the slide plate 3, the stop plate 4, and the limiting plate 5.
[0027] The limiting plate 5 is a vertically oriented plate whose bottom end is fixedly connected to the top end of the support plate 2, preferably forming an integral structure with the support plate 2 by welding. The setting of the limiting plate 5 allows the device to extend further upward above the support plate 2, increasing the overall protective height of the device, thereby providing more adequate lateral limiting and guiding effect when cigarette splatters.
[0028] The slide plate 3 is the core functional component for guiding and separating cigarettes. The slide plate 3 is fixedly connected to the upper inner side of the support plate 2; specifically, one side of it is welded to the support plate 2. The slide plate 3 is inclined, with its inclination direction forming a certain angle with the support plate 2. That is, the upper end of the slide plate 3 faces upwards and towards the inside of the rolling machine, and the inner end of the slide plate 3 extends towards the inside of the rolling machine to catch cigarettes falling from above. The inclination angle of the slide plate 3 is precisely designed. Since the coefficient of dynamic friction between the cigarette and the slide plate is 0.6, to ensure that the cigarette can slide smoothly under its own weight and avoid stopping due to excessive friction, the inclination angle between the slide plate 3 and the vertical plane containing the fixed plate 1 is preferably set to 50° in this embodiment. The lower end of the slide plate 3 extends above the waste cigarette belt, allowing cigarettes sliding along the slide plate 3 to fall accurately into the waste cigarette belt.
[0029] A baffle plate 4 is fixedly connected to the inner front end of the support plate 2 and the limiting plate 5, and the height of the baffle plate 4 is equal to the total height of the support plate 2 and the limiting plate 5, and it is located in front of the slide plate 3. The height and width of the baffle plate 4 cover the splash range when the cigarette falls. The main function of the baffle plate 4 is to cooperate with the upper part of the support plate 2 and the limiting plate 5 to form a physical barrier during the fall of the cigarette, preventing the cigarette from deviating from the receiving range of the slide plate 3 due to bouncing, and ensuring that all cigarettes fall onto the working surface of the slide plate 3. Since the rear end face of the support plate 2 is adjacent to the relevant body structure of the rolling and forming machine in the actual installation state, the body structure itself constitutes a natural barrier against the backward splashing of the cigarette, so there is no need to set a separate baffle plate on the rear end face of the support plate 2, which simplifies the device structure and avoids repeated interference with the original equipment components. The addition of the limiting plate 5 further improves the structural connection stability of the baffle plate 4, enabling the baffle plate 4 to withstand greater impact force from the cigarette, while increasing the blocking range against the upward bouncing of the cigarette.
[0030] The working process of this embodiment is as follows: During the operation of the ZJ118 cigarette rolling machine, when short-headed or double-length cigarettes are rejected downwards from the smoke conveying guide rail, they fall downwards under the influence of gravity. The cigarette first contacts the upper surface of the slide plate 3 of the waste-discarding smoke guide device. During this process, the front baffle plate 4, the upper part of the support plate 2, and the limiting plate 5 effectively prevent the cigarette from splashing outwards, ensuring that the cigarette lands stably on the working surface of the slide plate 3. Subsequently, under the influence of its own gravity, the cigarette smoothly slides downwards along the surface of the slide plate 3. Finally, the cigarette slides out from the lower end of the slide plate 3 and falls directly onto the waste smoke belt below, thus achieving the physical separation of short-headed cigarettes from the tobacco shreds falling into the cigarette collection bin.
[0031] In summary, the waste removal and smoke guiding device provided in this embodiment, through the combined structural design of fixed plate 1, support plate 2, sliding plate 3, blocking plate 4 and limiting plate 5, and with the 50° tilt angle of sliding plate 3 and tool-free installation structure, effectively realizes the automatic guiding and separation of the discarded cigarettes of the ZJ118 cigarette forming machine. The structure is reliable, easy to disassemble and maintain, and has a good anti-splash effect.
[0032] Although the specific embodiments of the invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the invention. Based on the technical solutions of the invention, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the invention.
