Description

Technical Field

[0001] This invention relates to the field of tobacco processing machinery, and in particular to a tobacco strip forming device and a cigarette rolling machine. Background Technology

[0002] After the cigarette rolling machine winds the tobacco into cigarette strips, they are conveyed downstream for cutting. During this process, the strips pass through a strip cutter. The purpose of the strip cutter is to cut off any substandard tobacco strips produced during machine startup or blockages, ensuring that subsequent qualified tobacco strips can be conveyed normally. Currently, the cutting blades in these strip cutters are fixed in position and cannot be adjusted, making it difficult to adapt to changes in the type of tobacco strip. Summary of the Invention

[0003] The purpose of this invention is to provide a tobacco strip cutting device that can adjust the cutting position of the cutter.

[0004] The first aspect of this invention discloses a cigarette packer, comprising:

[0005] Mounting rack;

[0006] Vertical board;

[0007] The base plate is fixedly connected to the vertical plate and is used to support and guide the conveying of cigarette bars in non-sticking conditions.

[0008] The cutter is positioned at the end of the base plate in an adjustable manner relative to the base plate along the conveying direction of the tobacco strips under non-sticking conditions;

[0009] A driving device, mounted on the mounting frame and connected to the vertical plate, is used to drive the vertical plate to swing during the strip-cutting process, thereby driving the cutter to cut the tobacco strip.

[0010] In some embodiments, the cutting edge of the cutter is a serrated edge.

[0011] In some embodiments, a first locking device is further included. The cutter includes a blade body and a cutting edge. The blade body has a first strip-shaped hole. The first locking device includes a first bolt passing through the first strip-shaped hole and a first threaded hole threadedly engaged with the bolt. After the threaded engagement of the first bolt and the first threaded hole is loosened, the first strip-shaped hole can slide relative to the first bolt so that the position of the cutter relative to the transverse plate along the conveying direction of the tobacco strip under non-sticking conditions is adjustable. After the threaded engagement of the first bolt and the first threaded hole is tightened, the relative position of the cutter and the base plate is locked.

[0012] In some embodiments, the base plate includes a horizontal plate and a bent plate bent relative to the horizontal plate, the cutter is disposed on the bent plate, and the bent plate and the horizontal plate are connected by an arc-shaped plate.

[0013] In some embodiments, the system further includes two guide strips disposed opposite to each other on the base plate. The two guide strips are used to allow the tobacco stick to pass through the gap between them in non-stripping conditions. The two guide strips guide the conveying of the tobacco stick from both sides of the tobacco stick.

[0014] In some embodiments, the distance between the two guide strips is adjustable.

[0015] In some embodiments, the base plate is provided with a second strip-shaped hole, which extends along the spacing direction of the two guide strips. The cigarette bar applicator also includes two second locking devices corresponding to the two guide strips. Each second locking device includes a second bolt passing through the second strip-shaped hole and a second threaded hole threaded to the bolt. After the threaded engagement of the second bolt and the second threaded hole is loosened, the guide strip can slide along the second strip-shaped hole to adjust the spacing between the two guide strips. After the threaded engagement of the second bolt and the second threaded hole is tightened, the relative position of the guide strip and the base plate is locked.

[0016] In some embodiments, the spacing between the two guide strips gradually decreases near the end of the cutter along the conveying direction of the tobacco stick in non-sticking conditions.

[0017] A second aspect of this invention discloses a cigarette rolling machine, comprising any of the cigarette strip forming devices described above.

[0018] Based on the cigarette bar forming device provided by this invention, the driving device drives the vertical plate to swing, which allows the cutter to cut and form the cigarette bar during the forming process. In non-forming conditions, the base plate supports and guides the cigarette bar conveying, ensuring normal and stable transport. The cutter is adjustable relative to the base plate along the cigarette bar conveying direction in non-forming conditions. By adjusting the position of the cutter relative to the base plate, the cutting position of the cutter on the cigarette bar during forming can be changed in a timely manner, thus adapting to forming conditions for more types of cigarette bars.

[0019] Other features and advantages of the invention will become clear from the following detailed description of exemplary embodiments of the invention with reference to the accompanying drawings. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0029] In the description of this invention, it should be understood that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0030] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0032] The cigarette bar maker in this embodiment includes a mounting frame 1, a vertical plate 2, a base plate 3, a cutter 4, and a driving device.

[0033] The base plate 3 is fixedly connected to the vertical plate 2. The base plate 3 is used to support and guide the conveying of the tobacco strips in non-stripping conditions. Non-stripping conditions refer to the conditions where the tobacco strip cutter does not cut or strip the tobacco strips. For example... Figure 1 As shown, in non-stripping conditions, the tobacco strip 100 conveyed from the upstream is supported and guided by the base plate 3 and then further conveyed downstream, for example, to be cut downstream.

[0034] like Figures 1 to 6 As shown, the cutter 4 is positioned at the end of the base plate 3, adjustable relative to the base plate 3 along the conveying direction of the tobacco sticks in non-sticking conditions. In the embodiment shown, in non-sticking conditions, the conveyor roller 300 rotates, and the conveyor belt 200 on the conveyor roller 300 conveys the tobacco sticks 100 downstream after passing through the base plate 3. Since the position of the cutter relative to the base plate 3 is adjustable, when switching to sticking conditions, the cutter can cut the tobacco sticks at multiple positions. Different types of tobacco sticks may have different lengths and / or positions of defective tobacco stick segments generated during equipment startup and other processes. Adjusting the cutting position of the cutter can more accurately cut waste tobacco stick segments of different types of tobacco sticks, reduce the cutting of qualified tobacco sticks, and improve resource utilization.

[0035] The drive unit is mounted on the mounting bracket 1 and is connected to the vertical plate 2. During the tobacco strip cutting process, the drive unit drives the vertical plate 2 to swing, thereby driving the cutter 4 to cut the tobacco strip. The drive unit may include a motor or other rotary power device. The drive unit drives the vertical plate 2 to swing, thus enabling the cutter to swing and cut the tobacco strip. Figure 1 As shown, in non-sticking conditions, the bottom plate is approximately horizontal, and the tobacco sticks are normally conveyed downstream through the bottom plate. When sticking is required, the drive device drives the vertical plate 2 to swing, and the bottom plate drives the cutter to swing accordingly. The bottom plate tilts upward, and the cutter 4 also rises. Then, the drive device drives the vertical plate 2 to swing back, and the bottom plate drives the cutter to swing horizontally. When the bottom plate returns to an approximately horizontal state, as shown... Figure 2 As shown, the cutter cuts the tobacco stick 100, and the cut tobacco stick segments fall into the waste tobacco box for collection. Then, the uncut tobacco sticks continue to be transported downstream normally, and are supported and guided by the bottom plate.

[0036] In this embodiment of the tobacco stick forming device, the driving device drives the vertical plate 2 to swing, which allows the cutter 4 to cut and form the tobacco sticks during forming. In non-forming conditions, the base plate 3 supports and guides the tobacco sticks during transport, ensuring smooth and normal transport. The cutter 4 is adjustable relative to the base plate 3 along the tobacco stick transport direction in non-forming conditions. Therefore, by adjusting the position of the cutter 4 relative to the base plate 3, the cutting position of the cutter 4 during forming can be changed in a timely manner, thus adapting to the forming conditions of more types of tobacco sticks.

[0037] In some embodiments, such as Figure 6 As shown, the blade 42 of the cutter 4 is a serrated blade. The serrated blade makes it easier to cut tobacco strips that are difficult to cut. At the same time, the serrated blade is safer to operate than a regular blade-faced cutter, and there are fewer safety hazards.

[0038] In some embodiments, the tobacco stick maker further includes a first locking device 51. The cutter 4 includes a blade body 41 and a blade edge 42. The blade body 41 is provided with a first strip-shaped hole 71. The first locking device 51 includes a first bolt passing through the first strip-shaped hole 71 and a first threaded hole threaded to the bolt. After the threaded engagement of the first bolt and the first threaded hole is loosened, the first strip-shaped hole 71 can slide relative to the first bolt so that the position of the cutter 4 relative to the transverse plate 31 is adjustable along the tobacco stick conveying direction in non-sticking conditions. After the threaded engagement of the first bolt and the first threaded hole is tightened, the relative position of the cutter 4 and the base plate 3 is locked. The first bolt can pass through the first strip-shaped hole 71 and the bending plate simultaneously and then engage with a nut. In this case, the first threaded hole is set on the nut. Alternatively, the first threaded hole can be directly set on the bending plate. In this case, the first bolt passes through the first strip-shaped hole and then engages with the first threaded hole on the bending plate.

[0039] In some embodiments, such as Figure 3 As shown, the base plate 3 includes a transverse plate 31 and a bent plate 32 that bends relative to the transverse plate 31. The cutter 4 is disposed on the bent plate 32, and the bent plate 32 and the transverse plate 31 are connected by an arc plate 33. The arc plate 33 is provided for transition. In non-sticking conditions, when the tobacco stick is being fed onto the base plate, the arc plate 33 allows the tobacco stick to enter the base plate more smoothly and steadily.

[0040] In some embodiments, such as Figures 1 to 5 As shown, the cigarette bar feeder also includes two guide bars arranged opposite each other on the base plate 3. These two guide bars are used to guide the cigarette bar through the gap between them when not in feeder mode. The two guide bars guide the cigarette bar from both sides. The arrangement of the two guide bars makes the cigarette bar feeding more stable and smooth.

[0041] In some embodiments, the distance between the two guide strips is adjustable. This embodiment can adjust the distance between the guide plates on both sides according to different cigarette specifications, quickly realize specification switching, and adapt to changes in different specifications of cigarettes and cigarette packs.

[0042] In some embodiments, as shown in the figure, the base plate 3 is provided with a second strip-shaped hole 72, which extends along the interval direction of the two guide strips. The cigarette bar applicator also includes two second locking devices 52 corresponding to the two guide strips one-to-one. The second locking device includes a second bolt passing through the second strip-shaped hole 72 and a second threaded hole that engages with the bolt thread. In the embodiment shown in the figure, the second threaded hole is located at the bottom of the guide strip. After the thread engagement of the second bolt and the second threaded hole is loosened, the guide strip can slide along the second strip-shaped hole 72 to adjust the interval distance between the two guide strips. After the thread engagement of the second bolt and the second threaded hole is tightened, the relative position of the guide strip and the base plate 3 is locked. In the embodiment shown in the figure, each end of each guide strip is engaged with a second strip-shaped hole through a locking device, thereby making the movement and locking of the guide strip more stable and reliable.

[0043] In some embodiments, as shown in the figure, the spacing between the two guide bars gradually decreases near the end of the cutter 4 along the conveying direction of the tobacco stick in non-stick-forming conditions. The tapered inlets of the two guide bars guide the tobacco stick into the base plate, facilitating smoother conveying of the tobacco stick.

[0044] In some embodiments, a cigarette rolling machine is also disclosed, including any of the above-described tobacco strip forming devices.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of the present invention or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of the present invention, and all such modifications and substitutions should be covered within the scope of the technical solutions claimed in the present invention.
