Description

Technical Field

[0001] The present invention relates to the field of cigarette conveying, and in particular to a conveying and feeding system for lightweight rod-shaped materials. Background Art

[0002] There are various ways to convey and feed lightweight rod-shaped materials (such as those in the cigarette industry), but all require relatively complex mechanical conveying structures, which have the disadvantages of high cost and cumbersome operation. In addition, some mechanical conveying structures do not have enough space to be installed, which limits their scope of use. If the equipment space is optimized and modified, the space occupied by the entire equipment will increase, which is not conducive to workshop planning and layout.

[0003] The object of the present invention is to design a lightweight rod-shaped material conveying and feeding device with a simple mechanical structure and high space utilization. Summary of the Invention

[0004] In order to overcome the above problems, the present application provides a system for conveying and feeding lightweight rod-shaped materials.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Reference Figure 1This embodiment is a system for conveying and feeding light rod-shaped materials, such as cigarettes, tobacco rods, etc. in the cigarette industry, or conveying and feeding light rod-shaped materials in other industries, mainly including

[0030] Frame 7, feed wheel 6, hopper 3 are installed on the frame 7. Frame 7 can also be a fixed plate or a fixed frame that is easy to install near the material conveying.

[0031] The hopper 3 is located above the feed wheel 6 and does not contact the surface of the feed wheel 6, and the bottom is hollow.

[0032] The feeding wheel 6 rotates clockwise to feed the material, and the feeding wheel 6 rotates slowly during feeding. The circumferential surface of the feeding wheel 6 is provided with a plurality of regularly arranged sunken troughs.

[0033] The hopper 3 comprises two parallel feeding chambers, each connected to a material conveying pipe 2, on which a pneumatic conveying device 1 is mounted. Specifically, the left side of the material conveying pipe 2 is connected to the side panel of the hopper 3, and the right side is connected to the upstream feeding device. The feeding chamber faces the trough below. When lightweight rod-shaped material is delivered to the inlet of the material conveying pipe 2 by the upstream feeding device, the pneumatic conveying device 1 (pneumatic conveyor) generates negative pressure through positive pressure, sucking the lightweight rod-shaped material into the material conveying pipe 2 and conveying it into the feeding chamber of the hopper 3. The lightweight rod-shaped material then falls by gravity into the trough of the feed wheel 6.

[0034] A discharging roller 4 is also rotatably mounted within the hopper 3. Specifically, it is mounted between the two side plates of the hopper 3 and located at the rear of the material discharging cavity. The rear side refers to the rear side relative to the rotational direction of the feed wheel 6. The discharging roller 4 is a rotating structure that primarily serves to align lightweight rod-shaped materials that would otherwise have fallen into the trough of the feed wheel 6, allowing them to enter the trough properly. This prevents the problem of lightweight rod-shaped materials falling out of alignment and thus being unable to be conveyed or fed.

[0035] In this embodiment, the feed wheel 6 rotates clockwise to feed the material. The feed wheel 6 rotates slowly during feeding, and the paddle roller 4 rotates in the opposite direction thereof. Slow rotation means that the speed of the feed wheel 6 is 20-30 r / min.

[0036] In a preferred embodiment, a partition cover plate 5 is installed above the hopper 3, and the partition cover plate 5 covers the top of the blanking cavity and separates the blanking cavity space in the hopper 3 into two independent blanking cavities.

[0037] In a preferred embodiment, two rows of sunken troughs are provided on the surface of the feed wheel 6, and hoppers 3 are installed above the two rows of troughs, which can achieve more efficient transportation and feeding of lightweight rod-shaped materials.

[0038] In the preferred embodiment, the hopper 3 is located above the feed wheel 6 in the direction from 9 o'clock to 12 o'clock. This design is based on installation space considerations. Positioning it on the side saves installation space at the top of the system. Secondly, its tilted position provides a certain lateral force component when the rod-shaped materials fall, causing them to roll backward (compared to the rotation direction of the feed wheel 6). This can ensure the spacing of the rod-shaped materials on the feed wheel 6 to a certain extent, increase the adjustment distance for the materials to fall into the chute, and prevent material accumulation. At the same time, the rod-shaped materials are driven by the feed wheel 6, making it easier for them to enter the chute.

[0039] In other embodiments, the hopper 3, the partition cover 5, the material-dispensing roller 4 and other parts are made of 45# steel. The material conveying pipe 2 is a stainless steel material conveying pipe 2 with an inner diameter of 10 mm.

[0040] It should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
