Description

Technical Field

[0001] The invention belongs to the technical field of cigarette making auxiliary equipment, and in particular relates to a waste cigarette rod and shredded tobacco recovery device. Background Art

[0002] like Figure 1 As shown, in the process of preparing cigarettes, cigarette factories generally have waste tobacco rods of varying lengths but relatively certain diameters, referred to as waste tobacco rods. When recycling the tobacco wrapped in the waste tobacco rods, the tobacco 1 and the coil paper 2 need to be cut and separated.

[0003] At present, domestic tobacco factories mainly use manual processing to process waste cigarette rods, but manual processing is inefficient, labor-intensive, time-consuming, and easy to break. Although patents such as CN205284978U and CN105495679B disclose relevant mechanical equipment for processing defective cigarette rods, they can also be used to process waste cigarette rods. However, after the defective cigarette rods are cut by the above equipment, the tobacco and the coil paper fall into the vibration separation silo together for vibration separation.

[0004] It can be seen that the existing processing equipment has the problem of incomplete separation and easy to cause the tobacco to break. Summary of the invention

[0005] The embodiment of the present application provides a waste tobacco rod tobacco recycling device that can completely separate tobacco shreds and prevent the tobacco shreds from breaking during the processing process.

[0007] The coil paper cutter and the coil paper stripping device are arranged alternately at the waste cigarette rod outlet of the waste cigarette rod conveying device, and are arranged in a plurality of circumferentially spaced intervals along the waste cigarette rod outlet; wherein,

[0008] The coil paper cutter is used to cut the coil paper of the waste cigarette rod;

[0009] The coil paper stripping device is used to drive the cut coil paper to move outward to separate it from the waste tobacco rods.

[0010] In some possible implementations, the coil paper peeling device includes a peeling pin wheel and a pin wheel motor driving the peeling pin wheel to rotate;

[0011] The wheel body of the stripping needle wheel is provided with a hooked pricking needle for piercing the coil paper of the waste cigarette rods and tearing it off and taking it away.

[0012] In some possible implementations, a paper-coil separation fork is further provided on the frame at the bottom of the peeling pin wheel;

[0013] The hooked needle on the stripping needle wheel passes through between a pair of fork arms of the coil paper separation fork.

[0014] A paper coil collecting cylinder is also provided on the frame below the stripping pin wheel.

[0015] In some possible implementations, the coil paper collecting cylinder is further provided with a fan for discharging the coil paper from a discharge port of the coil paper collecting cylinder.

[0016] In some possible implementations, a tobacco collection hopper is further provided on the frame directly below the waste tobacco rod outlet.

[0017] In some possible implementations, the paper cutter and the needle wheel are installed in a cross-shaped and symmetrical manner.

[0018] In some possible implementations, the waste cigarette rod conveying device includes a material guide pipe and a double-circular pressure wheel for driving the waste cigarette rod to move in the material guide pipe.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0038] The embodiment of the present invention provides a waste tobacco rod and shredded tobacco recycling device, which is used to solve the problem of incomplete separation of shredded tobacco and easy breakage of shredded tobacco in the prior art. The waste tobacco rod 1 refers to the waste tobacco rod material of different lengths but relatively constant diameters that exists in the process of making cigarettes in a cigarette factory. The waste tobacco rod material is generally composed of shredded tobacco 101 and coil paper 102 wrapped around the shredded tobacco.

[0039] See also Figure 2-Figure 6The waste cigarette rod tobacco recovery device of the embodiment of the present application includes a waste cigarette rod conveying device 3, a coil paper cutter 4 and a coil paper peeling device 5 which are arranged on a frame 2 from top to bottom. The coil paper cutter 4 and the coil paper peeling device 5 are arranged alternately at the waste cigarette rod outlet of the waste cigarette rod conveying device 3 along the waste cigarette rod outlet in a circumferential direction.

[0040] See also Figure 2 , Figure 3 and Fig. 9 In this embodiment, the waste cigarette rods are driven downward by the waste cigarette rod conveying device 3 to the position of the paper coil cutter 4, and the paper coil cutter 4 moves upward relative to the waste cigarette rods to cut the paper coil into multiple strips. When the cut waste cigarette rods continue to move to the position of the paper coil stripping device 5 under the drive of the waste cigarette rod conveying device 3, the multiple cut paper coils are driven by their respective corresponding paper coil stripping devices 5 to move outward to be separated from the tobacco shreds of the waste cigarette rods and enter their respective collection channels, so there is no need to add a vibration separation device, and the cleanliness, moisture and aroma of the collected tobacco shreds are almost not affected, and no secondary crushing and pollution will occur. It can be directly sent back to the tobacco shreds suction hopper of the cigarette making machine to be recycled online.

[0041] It is necessary to explain that, see Figure 3 In some embodiments, the coil paper stripping device 5 in the waste tobacco rod tobacco recycling equipment of the embodiment of the present application includes a stripping pin wheel 501 and a pin wheel motor 502 for driving the pin wheel to rotate, and an outwardly protruding hooked needle 503 is circumferentially arranged on the wheel body of the pin wheel for piercing the coil paper of the waste tobacco rod and tearing it off.

[0042] See also Figure 3 and Figure 6 The working principle of the above embodiment is as follows: the waste tobacco rod is driven downward by the waste tobacco rod conveying device 3 to the cutting knife position, the coil paper is cut, and a stripping pin wheel 501 is provided at a suitable position below. The pin wheel is driven by a pin wheel motor 502 to rotate relative to the waste tobacco rod. A hooked pricking needle 503 on the pin wheel pierces the coil paper 102 and tears it apart, thereby separating the shredded tobacco 101 from the coil paper 102. After separation, the shredded tobacco 101 and the coil paper 102 enter their respective collecting channels. The shredded tobacco is separated thoroughly and cleanly, and automatic and continuous operation can be realized, with high separation efficiency.

[0043] What needs to be explained here is that, of course, the paper stripping device 5 can also adopt the following structure: an annular groove adapted to the arc surface of the stripped paper strip is provided on the outer circumferential surface of the rotatable stripping wheel body, and a negative pressure suction cup is provided in the annular groove. The split paper strip is adsorbed in the annular groove by the negative pressure provided by the negative pressure suction cup. As the stripping wheel body continues to rotate, the split paper strip is driven to move outward relative to the tobacco to achieve separation. However, the paper stripping device 5 with the above structure has the problem of separating the tobacco strip and clogging the suction cup with tobacco. At the same time, in order to separate the adsorbed paper strip from the stripping wheel body, the negative pressure air path of the negative pressure suction cup can only be released after processing one waste cigarette strip. After the paper strip is removed from the stripping wheel body, the tobacco of the next waste cigarette strip can be recovered, which is not conducive to continuous operation.

[0044] See also Figure 7-Figure 9 In some embodiments, a coil separation fork 6 is further provided on the frame 2 to separate the coil 102 from the pin wheel 501. The coil separation fork 6 is located at the bottom of the pin wheel. The hooked needle 503 on the peeling pin wheel 501 passes through a pair of fork arms of the coil separation fork 6 and ensures that the hook 5031 on the hooked needle 503 is located outside the coil separation fork 6. Specifically, the coil separation fork 6 is inclined upward and the fork opening faces the waste cigarette strip. The distance between the pair of fork arms of the coil separation fork 6 is less than the width of the coil strip on the corresponding needle. In this embodiment, when the coil is brought to the position of the coil separation fork 6 by the hooked needle 503, the coil falls off the hooked needle 503 due to the obstruction of the coil separation fork 6.

[0045] It is understandable that in some other possible implementations, a paper coil collection cylinder 7 is provided on the frame 2 below the stripping pin wheel 501, and a tobacco shred collection hopper 8 is provided on the frame just below the waste tobacco rod outlet. When the paper coil 102 on the pin wheel is separated from the pin wheel by the paper coil separation fork 6, it enters the paper coil collection cylinder 7 for collection, and the tobacco shreds separated from the paper coil fall into the tobacco shred collection hopper 8 for collection under the action of gravity.

[0046] See also Figure 8 and Fig. 9 Specifically, a fan 9 may be provided on the paper coil collecting cylinder 7 to discharge the paper coil from the discharge port of the paper coil collecting cylinder 7. After being cut by the cutter, the paper coil is diverted and guided to the inlet of the paper coil collecting cylinder 7 under the traction of the stripping pin wheel 501, separated from the pin wheel by the separation fork, and after entering the paper coil collecting cylinder 7, it is sent to the cylinder outlet under the guidance of the airflow of the fan 9, and the tobacco directly enters the tobacco collecting hopper 8 below.

[0047] See also Figure 8 and Fig. 9In some embodiments, the waste cigarette strip conveying device 3 includes a guide pipe 301 and a double circular pressure wheel 302 for driving the waste cigarette strip 1 to move in the guide pipe 301. A motor for driving the double circular pressure wheel 302 to move is provided on the frame. Driven by the double circular pressure wheel 302, the waste cigarette strip 1 passes through the double circular pressure wheel 302 and flows out of the guide pipe 301, and the paper cutter 4 and the needle wheel 501 are symmetrically installed on the outside of the bottom of the guide pipe 301 in a cross shape.

[0048] In actual design, the double circular pressure wheels 302 and the needle wheel 501 are connected to the same driving motor through a gear transmission mechanism, that is, the double circular pressure wheels 302 and the needle wheel 501 are driven by one motor, thereby reducing the size of the device.

[0049] See also Fig. 9 Specifically, a cutter slot 10 and a needle slot 11 are provided on the bottom tube wall of the guide tube 301, the hooked needle 503 on the needle wheel 501 is inserted into the needle slot 11 and extends into the guide tube 301, the coil cutter 4 is installed on the guide tube 301 through the knife seat and the blade passes through the cutter slot 10 and extends into the guide tube 301, thereby cutting the waste cigarette rod moving in the guide tube 301, and the fork of the coil paper separation fork 6 extends to the bottom end of the needle slot 11.

[0050] In order to facilitate the insertion of the waste cigarette rod 1 , a conical guide section is provided at the top of the guide tube 301 .

[0051] In other embodiments, in order to adapt to the recovery of waste tobacco rods of different sizes, the distance between the two sets of paper cutters 4 and the center distance of the double circular pressing wheels 302 are adjustable.

[0052] See also Fig.10 In addition, in order to improve the safety of equipment operation, the frame 2, the waste cigarette rod conveying device 3, the coil paper cutter 4, and the coil paper stripping device 5 are all accommodated in the shell 12, and openings are respectively provided on the upper side of the shell 12 for docking with the waste cigarette rod inlet of the waste cigarette rod conveying device 3, the coil paper collecting tube 7 and the tobacco collecting bucket 8.

[0053] Of course, for those skilled in the art, the above only provides a specific structure of the waste cigarette rod conveying device 3. Any transmission structure in the prior art that can realize the conveying of waste cigarette rods should fall within the scope of protection of the embodiments of the present application.

[0054] The above embodiments are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here. The obvious changes or modifications derived therefrom are still within the scope of protection of the present invention.
