Description

Technical Field

[0001] The invention belongs to the technical field of cigarette production equipment, and in particular relates to a device for sorting and recovering broken and residual cigarettes. Background Art

[0002] In the complex process of cigarette production, from silk making, cigarette rolling to packaging and other links, it is inevitable that some unqualified cigarettes that do not meet the quality standards will appear. The problems of these cigarettes may include but are not limited to length deviation, skewed cuts of cigarettes, uneven cutting of mouthpieces, gaps between cigarettes and mouthpieces, etc. These problems directly affect the final quality of cigarette products. However, if these cigarettes with quality problems are directly discarded, it will not only cause a huge waste of raw materials such as tobacco and popping beads, but also significantly increase the production costs of enterprises and reduce overall production efficiency.

[0003] Traditionally, cigarette manufacturers have been dealing with these unqualified cigarettes in a rough manner, often lacking an efficient sorting and recycling mechanism. On the one hand, manual screening and sorting are not only inefficient, but also difficult to ensure the accuracy and consistency of screening. On the other hand, sorting equipment with a low degree of automation often cannot accurately identify and handle various quality defects, resulting in uneven quality of recycled cigarettes and difficulty in reuse.

[0004] The present invention is proposed to solve the above-mentioned problems. Summary of the invention

[0005] The purpose of the present invention is to provide a device capable of efficiently sorting and recovering broken and residual cigarettes, so as to solve the technical problems of low efficiency and low automation in sorting and recovering unqualified cigarettes in the prior art during cigarette production.

The double-sided synchronous belt 2 is provided with a tooth structure, which is V-shaped or trapezoidal. The double-sided synchronous belt 2 includes an upper synchronous belt and a lower synchronous belt.

[0021] Preferably, the spiral rod 3 is installed above the double-sided synchronous belt 2 through a support frame, and one end or both ends of the spiral rod 3 are connected to a motor, and the motor is a DC motor, a servo motor or a stepper motor with a power of 20W to 100W and a rated speed of 120rpm-1000rpm. The axis of the spiral rod 3 is parallel to the movement direction of the double-sided synchronous belt 2, and the spacing between the spiral rod 3 and the double-sided synchronous belt 2 is 0.5cm-1cm.

[0022] Preferably, the large drum wheel 4 and the small drum wheel 5 are fixed by support frames respectively, and the large drum wheel 4 and the small drum wheel 5 are connected by gears.

[0023] Preferably, the included angle between the tail plate 6 and the double-sided synchronous belt 2 is 30 degrees or 45 degrees.

[0024] Preferably, the number of the fan plates 7 is one or more, the swing angle range of the fan plates 7 is 30 degrees to 60 degrees, and the swing frequency range of the fan plates (7) is 1-20 Hz.

[0025] Preferably, the funnel 1 is made of wear-resistant and smooth metal or plastic.

[0027] Preferably, the surface of the double-sided synchronous belt 2 is also covered with an anti-slip material, and the anti-slip material is rubber or polyurethane.

[0028] Preferably, one end of the connecting rod 8 is connected to a driving mechanism, and the driving mechanism is a cylinder.

[0029] The working principle of the cigarette arrangement device of the present invention is as follows:

[0030] 1. Initial distribution and dispersion of cigarettes

[0031] Function of Funnel 1:

[0032] The funnel 1 is located at the top of the whole device and serves as the entrance for cigarettes. It is designed with wear-resistant and smooth metal or plastic to reduce friction and resistance during the sliding of cigarettes. Cigarettes fall freely from the funnel 1 and initially form a certain amount of accumulation.

[0033] Screw 3 dispersion:

[0034] The spiral rod 3 is arranged near the outlet of the hopper 1 and is located above the double-sided synchronous belt 2. The spiral rod 3 is driven to rotate by a motor, which is a DC motor, a servo motor or a stepper motor with a power of 20W to 100W and a rated speed of 120rpm-1000rpm. The wide and shallow spiral blades of the spiral rod 3 gently push and disperse the cigarettes, ensuring that the cigarettes can maintain proper spacing and direction when falling onto the double-sided synchronous belt 2 to avoid stacking and squeezing.

[0035] 2. Cigarette transfer and initial alignment

[0036] Double-sided synchronous belt 2 transmission:

[0037] The double-sided synchronous belt 2 is horizontally arranged and connected to the motor, which is a servo motor or a stepper motor with a power of 100W to 500W and a rated speed of 1500rpm-3000rpm. The double-sided synchronous belt 2 has a V-shaped or trapezoidal tooth structure to provide stable transmission capacity. The double-sided synchronous belt 2 includes an upper synchronous belt and a lower synchronous belt, which work together to increase the friction with the cigarette through the anti-slip material on its surface, which is rubber or polyurethane, to ensure that the cigarette will not slip or deviate during the transmission process. After the cigarette slides from the spiral rod 3 to the double-sided synchronous belt 2, it is gradually transmitted forward as the synchronous belt moves.

[0038] Initial alignment:

[0039] During the transmission process of the double-sided synchronous belt 2, the cigarettes are initially aligned due to the stability and anti-slip property of the synchronous belt. At this point, although the arrangement of the cigarettes is not neat enough, serious stacking and misalignment have been avoided.

[0040] 3. Further Arrangement and Alignment

[0041] Drum finishing:

[0042] The large drum wheel 4 and the small drum wheel 5 are arranged side by side above the double-sided synchronous belt 2, connected by gears, and rotate synchronously. The large drum wheel 4 and the small drum wheel 5 are designed to further arrange the cigarettes, initially flatten the cigarettes, and slightly adjust the position and angle of the cigarettes through the structure or texture of their surface, so that the cigarettes can maintain the best arrangement during the transmission process.

[0043] 4. Guided discharge and final finishing

[0044] Guidance of tail plate 6:

[0045] The tail plate 6 is arranged downstream of the small drum wheel 5, and is in a slope shape, with one end against the small drum wheel 5 and the other end against the double-sided synchronous belt 2. The tail plate 6 is designed at an angle of 30 degrees or 45 degrees, effectively guiding the cigarettes to slide down the slope. The slope design reduces the collision and squeezing between cigarettes, and at the same time enables the cigarettes to slide along the predetermined path to the next stage.

[0046] Final finishing of fan plate 7:

[0047] The fan plate 7 is located downstream of the tail plate 6, and there are one or more of them. They are connected to the driving mechanism through the connecting rod 8, and the driving mechanism is a cylinder. When the cigarette slides down the slope to the fan plate 7, the driving mechanism starts, and the back-and-forth movement of the connecting rod 8 drives the fan plate 7 to swing cyclically within an angle range of 30 degrees to 60 degrees, and the swing frequency range of the fan plate 7 is 1-20 Hz. This cyclic swinging action uses inertia to further disperse and organize the cigarettes into an orderly arrangement state along the V-shaped or trapezoidal tooth structure direction of the double-sided synchronous belt 2.

[0048] The number and swinging mode of the fan plates 7 can be adjusted according to actual needs to adapt to cigarettes of different specifications and quantities, mainly based on the actual needs of the following aspects:

[0049] The adjustment of the number of fan plates mainly includes the following two aspects:

[0050] Cigarette specifications: Different specifications of cigarettes (such as length, diameter, etc.) require different space and strength when sorting. For longer cigarettes, more fan plates may be needed to ensure that the cigarettes can be fully dispersed and sorted during the sliding process; while for shorter cigarettes, fewer fan plates may be needed to achieve the sorting effect.

[0051] Number of cigarettes: When there are a large number of cigarettes to be sorted, increasing the number of fan plates can more effectively disperse the cigarettes and prevent poor sorting results due to cigarette accumulation. On the contrary, if the number of cigarettes is small, too many fan plates may cause unnecessary waste and complexity.

[0052] There are two main aspects to adjust the swing mode:

[0053] Swing angle: The swing angle of the fan plate directly affects its ability to sort cigarettes. When the swing angle is large, the fan plate has a greater force on the cigarettes, which is suitable for scenes that require a stronger sorting force; when the swing angle is small, it is suitable for scenes that require a softer sorting force.

[0054] Swing frequency: The swing frequency of the fan plate determines the speed of its arrangement of cigarettes. When a large number of cigarettes need to be arranged quickly, the swing frequency of the fan plate can be increased; when a small number of cigarettes need to be arranged more carefully, the swing frequency can be reduced.

[0055] Specifically, the number of the fan plates 7 can be adjusted by adding or reducing the fan plate components. The swing mode can be adjusted by changing the control parameters of the drive mechanism (cylinder), such as the stroke, speed and swing frequency of the cylinder.

[0056] 5. Output orderly arranged cigarettes

[0057] After the above steps, the cigarettes are output from the device in an orderly state. These neatly arranged cigarettes are convenient for subsequent packaging or further processing.

[0058] Beneficial effects of the present invention:

[0059] 1. The cigarette sorting device provided by the present invention realizes efficient and automatic sorting of unqualified cigarettes through the coordinated action of multiple components such as the funnel, the spiral rod, the double-sided synchronous belt, the large drum wheel, the small drum wheel, the tail plate and the fan plate. Compared with the traditional manual screening and sorting method, it greatly improves the sorting efficiency and automation, reduces the labor cost, and improves the accuracy and consistency of sorting.

[0060] 2. The cigarette sorting device provided by the present invention can effectively sort and recycle unqualified cigarettes, thus avoiding the waste of raw materials such as tobacco shreds and popping beads caused by direct disposal, thereby significantly reducing the production cost of the enterprise. At the same time, the sorted cigarettes can be reused, improving the utilization rate of raw materials.

[0061] 3. The cigarette arrangement device provided by the present invention has a flexible design and can be adjusted according to cigarettes of different specifications and quantities. For example, the number and swinging mode of the fan plates can be configured according to actual needs to meet the needs of different production scenarios. This highly adaptable design enables the device to have a wider range of applications.

[0062] 4. The cigarette sorting device provided by the present invention, as a part of the cigarette production line, can improve the overall efficiency of the entire production line with its efficient and stable operation, reduce production interruptions and delays caused by improper handling of unqualified cigarettes, and improve the continuity and stability of the production line.

[0084] One end of the connecting rod (8) is connected to a driving mechanism, and the driving mechanism is a cylinder.

[0085] Here’s how it works:

[0086] 1. Initial distribution and dispersion of cigarettes

[0087] Function of the funnel (1):

[0088] The funnel (1) is located at the top of the entire device and serves as an entrance for cigarettes. It is designed with wear-resistant and smooth metal materials to reduce friction and resistance during the sliding of cigarettes. Cigarettes fall freely from the funnel (1) and initially form a certain amount of accumulation.

[0089] Screw (3) dispersion:

[0090] The spiral rod (3) is arranged near the outlet of the hopper (1) and is located above the double-sided synchronous belt (2).

[0091] 2. Cigarette transfer and initial alignment

[0092] Double-sided synchronous belt (2) transmission:

[0093] The double-sided synchronous belt (2) is horizontally arranged and connected to the motor, and has a V-shaped tooth structure, providing stable transmission capacity. The double-sided synchronous belt (2) includes an upper synchronous belt and a lower synchronous belt, which work together to increase the friction with the cigarette through the anti-skid rubber material on the surface, ensuring that the cigarette will not slip or deviate during the transmission process. After the cigarette slides from the spiral rod (3) onto the double-sided synchronous belt (2), it is gradually transmitted forward as the synchronous belt moves.

The slope design reduces the collision and squeezing between cigarettes, while allowing the cigarettes to slide along a predetermined path to the next stage.

[0102] Final finishing of the fan plate (7):

[0103] The fan plates (7) are located downstream of the tail plate (6), and there are four of them, which are connected to the driving mechanism (cylinder) through the connecting rod (8). When the cigarette slides down the slope to the fan plate (7), the driving mechanism starts, and the back-and-forth movement of the connecting rod 8 drives the fan plate 7 to swing in a 45-degree cycle, and the swing frequency of the fan plate (7) is 3 Hz.
