Description
Technical Field
[0001] This invention relates to the field of tobacco processing technology, and in particular to a stem adjustment component and a stem processing device. Background Technology
[0002] In the modern tobacco processing production line, the tobacco stem processing usually includes core processes such as washing stems, moistening stems, pressing stems, and cutting stems. The role of the pressing machine is to break the woody structure inside the tobacco stems through mechanical pressure, extruding them into flat stem strips of a certain thickness. These stem strips then need to be finely cut by the cutting machine, the core objective of which is to use a cutter to cut the stem strips into stem shreds.
[0003] In actual production, the stems, after being squeezed by the pressing machine and conveyed to the cutting machine, often exhibit a highly disordered stacking state. This physical state results in a lack of basic neatness when the stems enter the next stage. Existing conveying processes mostly use simple conveying troughs. Although the troughs can push the material forward, their vibration mode mainly serves a displacement function and lacks the function of directional guidance for the material's posture. When the disordered stems are conveyed to the cutting blade of the cutting machine, they still maintain an irregular arrangement. A large number of stems enter the cutting area in a horizontal, inclined, or even vertical posture. This uncontrolled posture directly leads to uneven stem lengths and easily generates tobacco dust. Tobacco dust absorbs water and clumps during subsequent processing, affecting quality and having a significant negative impact on subsequent drying, feeding processes, and the final overall sensory effect of cigarettes. Therefore, how to achieve automatic straightening and directional arrangement of stems before cutting has become an urgent technical issue to be solved in order to improve the level of refinement in tobacco processing. Summary of the Invention
[0004] The purpose of this invention is to provide a stem adjustment component and a stem processing device to solve the problem in the prior art where the stem length direction is not parallel to the blade of the cutter during the stem cutting process, resulting in a large amount of tobacco dust after the stem is cut.
[0005] To achieve this objective, the present invention adopts the following technical solution: The present invention provides a stem adjustment assembly, including a first vibration groove, a conveyor belt, and a second vibration groove. The first vibration groove is installed at an inclination, and the conveyor belt is installed on the lower side of the lower end of the first vibration groove. The second vibration groove is provided on the lower side of the output end of the conveyor belt. A side plate is provided on the surface of the first vibration groove near the conveyor belt. The side plate is perpendicular to the conveying direction of the conveyor belt. The central axis of the conveyor belt and the central axis of the second vibration groove coincide. The side plates are parallel to each other, and a channel is formed between the side plates. The width of the channel is shorter than the length of the stem. The stem slides onto the conveyor belt through the channel. The length direction of the stem is parallel to the length direction of the channel. The first vibration groove and the second vibration groove can drive the stem to vibrate.
[0006] Preferably, the side plate has a protrusion on its surface, which abuts against the stem.
[0007] Preferably, the first vibration groove includes a panel, the side plate is vertically mounted on the panel, an excitation motor is mounted on the side of the panel, the excitation motor drives the panel to vibrate, a leakage hole is opened on the panel, a first bracket is provided on the lower side of the first vibration groove, and a collection tray is slidably inserted into the first bracket.
[0008] Preferably, a telescopic rod is sleeved inside the first bracket, and the top of the telescopic rod is connected to the panel by a spring. The telescopic rod slides along the axis of the first bracket.
[0009] Preferably, a baffle is installed on the side of the conveyor belt away from the first vibrating trough.
[0010] Preferably, the surface of the conveyor belt is provided with anti-slip texture.
[0011] Preferably, a second bracket is installed on the lower side of the conveyor belt. The second bracket is mounted on a lifting platform. The lifting platform includes a hydraulic cylinder and a push rod. The push rod is connected to the second bracket and slides inside the hydraulic cylinder. The hydraulic cylinder pushes the push rod to move along its own axis.
[0012] Preferably, the second vibrating trough includes a vibrating frame and a trough body, with the output end of the conveyor belt disposed on the trough body, and the vibrating frame driving the trough body to vibrate.
[0013] Preferably, the stalk adjustment assembly further includes a vision sensor, which captures an image of the input port position of the channel, and the excitation motor can adjust its operating frequency according to the image captured by the vision sensor.
[0014] A stem processing device includes the stem adjustment assembly described above, and further includes a stem pressing machine and a stem cutting machine. The stem pressing machine discharges stems onto a first vibrating groove, and the stem cutting machine receives stems from a second vibrating groove. The stems in the second vibrating groove are parallel to the cutter inside the stem cutting machine.
[0015] Beneficial effects: After the stems are transferred to the first vibrating groove by the stem pressing machine, the stems can be further broken up by the vibration of the first vibrating groove. Since the first vibrating groove is installed at an angle, the stems will slide to one side of the conveyor belt. During the process of entering the channel, since the channel width is less than the length of the stems, the length direction of the stems entering the channel is parallel to the length direction of the channel. By adjusting the arrangement direction of the stems by the side plate, the occurrence of tobacco dust can be reduced and the quality of stem output can be improved when the stems enter the stem cutting machine through the second vibrating groove.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0020] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0021] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.
[0022] In the tobacco processing process, the stems processed by the stem pressing machine need to be cut into stem shreds by the stem cutting machine.
[0023] However, during the processing of the pressing machine, the pressed stems are disordered and clumped together. When the stems are conveyed to the cutting machine through the conveying trough, they are still arranged irregularly, resulting in excessive tobacco dust during cutting. This seriously affects the quality of stem cutting and the overall process effect of subsequent tobacco processing.
[0024] To solve the above problems, such as Figure 1 As shown, the present invention provides a stem adjustment assembly, including a first vibration groove 1, a conveyor belt 2, and a second vibration groove 3. The first vibration groove 1 is installed at an angle, and the conveyor belt 2 is installed on the lower side of the lower end of the first vibration groove 1. The second vibration groove 3 is provided on the lower side of the output end of the conveyor belt 2. A side plate 12 is provided on the surface of the first vibration groove 1 near the conveyor belt 2. The side plate 12 is perpendicular to the conveying direction of the conveyor belt 2. The central axis of the conveyor belt 2 and the central axis of the second vibration groove 3 coincide. The side plates 12 are parallel to each other, and a channel is formed between the side plates 12. The width of the channel is shorter than the length of the stem 4. The stem 4 slides onto the conveyor belt 2 through the channel. The length direction of the stem 4 is parallel to the length direction of the channel. The first vibration groove 1 and the second vibration groove 3 can drive the stem 4 to vibrate.
[0025] The stem processing device of the present invention also includes a stem pressing machine and a stem cutting machine. The stem pressing machine discharges the stems 4 onto the first vibrating groove 1, and the stem cutting machine receives the stems 4 from the second vibrating groove 3. The stems 4 in the second vibrating groove 3 are parallel to the cutter inside the stem cutting machine.
[0026] After the stem 4 is fed into the first vibrating groove 1 by the stem pressing machine, the first vibrating groove 1 vibrates and operates. Under the vibration state, the stem 4 entering the upper surface of the first vibrating groove 1 is vibrated, so that the stem 4 is in a state of continuous vibration. At the same time, since the first vibrating groove 1 is in a state of inclination, the stem 4 on the first vibrating groove 1 will slide downward. During the sliding process, the vibrating first vibrating groove 1 pushes and changes its position continuously, so that the stem 4 enters the channel in the same direction as its own length. Finally, it slides along the channel onto the conveyor belt 2. Since the central axis of the conveyor belt 2 and the second vibrating groove 3 are coincident, after the stem 4 enters the stem cutting machine along the second vibrating groove 3, the cutter will cut the stem 4 in the length direction to turn it into stem shreds. At this time, the cutter is parallel to the length direction of the stem 4, which reduces the appearance of tobacco dust and makes the final stem shreds of higher quality and more uniform length.
[0027] Additionally, some stems 4 may not enter the channel and fall onto the conveyor belt 2. This invention can adjust the position of some stems 4 to reduce the probability of smoke dust appearing.
[0028] It should be noted that the present invention adjusts the position of some of the stem strips 4. The second vibration groove 3 can adjust the stem strips 4, which are already parallel to the cutter, to be more closely aligned. This ensures that the stem strips 4 sent out from the channel can always remain parallel to the cutter, reducing the occurrence of stem slippage and allowing the stem strips 4 to be cut into more and more stem filaments.
[0029] Meanwhile, a conveyor belt 2 is set between the first vibration groove 1 and the second vibration groove 3 as a buffer, so that the stem 4 that has just fallen from the first vibration groove 1 remains relatively stationary after entering the conveyor belt 2. This allows the stem 4 sent out from the channel to maintain its own position and avoids additional shaking that would interfere with its own position if it falls directly into the second vibration groove 3. After the stem 4 is sent out from the first vibration groove 1, it enters the conveyor belt 2 and remains stationary before falling into the second vibration groove 3. This avoids large-scale jumping of the stem 4 and keeps most of the length of the stem 4 parallel to the cutting blade. This improves the uniformity of the stem length during the cutting process and reduces the probability of tobacco dust.
[0030] The side plate 12 has a protrusion on its surface. The protrusion can be integrally formed with the side plate 12 or it can be attached to the surface of the side plate 12 by bonding. The protrusion abuts against the stem 4. The protrusion and the stem 4 can directly contact each other on the surface of the side plate 12. During the contact process, the contact area between the stem 4 and the side plate 12 can be reduced, thereby reducing the problem that the stem 4 cannot slide due to excessive friction with the side plate 12, so that the stem 4 can slide smoothly on the first vibration groove 1.
[0031] The first vibration groove 1 of the present invention includes a panel 11, a side plate 12 is vertically mounted on the panel 11, an excitation motor 13 is mounted on the side of the panel 11, the excitation motor 13 drives the panel 11 to vibrate, a leakage hole is provided on the panel 11, a first bracket is provided on the lower side of the first vibration groove 1, and a collection tray is slidably inserted into the first bracket.
[0032] The perforated screen allows broken stems and debris to be removed from the sieve panel 11 and fall into the collection tray. Since the collection tray can be pulled out, it can be manually emptied for subsequent use, which reduces the amount of broken stems and debris entering the stem cutter.
[0033] A telescopic rod is fitted inside the first support. The top of the telescopic rod is connected to the panel 11 via a spring. The telescopic rod slides along the axis of the first support, and its extension height can be adjusted by reciprocating within the first support. The first support is also in a columnar state, supported on the ground. The height of the telescopic rod can be adjusted hydraulically within the first support, or positioning holes can be opened on the first support and the telescopic rod. By passing a positioning pin through the positioning hole, the telescopic rod can be fixed inside the first support, and the positioning pin can be removed to freely adjust the height of the telescopic rod. A spring between the telescopic rod and the panel 11 allows the panel 11 to vibrate under the drive of the excitation motor 13, thereby causing the strips 4 on the panel 11 to vibrate so that they can enter the channel. By setting the telescopic rod, the working angle of the first vibrating groove 1 can be adjusted, thereby adjusting the angle of inclination towards the conveyor belt 2. When facing strips 4 of different specifications, the inclination angle of the first vibrating groove 1 can be adjusted so that the strips 4 can smoothly slide onto the conveyor belt 2.
[0034] In this invention, the side plate 12 has a bent portion formed on its lower side, which is attached to the panel 11. The side plate 12 can be attracted to the panel 11 by magnetic attraction. By pushing the panel 11, its installation position can be changed, thereby allowing the width between the side plates 12 to be flexibly adjusted to accommodate different thicknesses of the stems 4. This allows the stems 4 of different thicknesses to slide along the channel into the conveyor belt 2 and be cut by the cutter along the length direction.
[0035] A guide plate is installed on the side of the panel 11 of the first vibrating trough 1 near the conveyor belt 2. The bar 4 can slide along the guide plate onto the conveyor belt 2, which can prevent the bar 4 from falling directly onto the conveyor belt 2 and causing collision and overturning, thus improving the stability of the bar 4 during the conveying process. The guide plate can be rotatably installed on the side of the panel 11 near the conveyor belt 2 by means of a hinge.
[0036] A baffle is installed on the side of the conveyor belt 2 away from the first vibrating trough 1. The baffle can prevent the strips 4 that slide off the panel 11 from falling to the ground, thus reducing waste.
[0037] The surface of the conveyor belt 2 is provided with anti-slip texture. By providing anti-slip texture, the gripping force of the conveyor belt 2 on the strand 4 can be improved, so that the strand 4 can be prevented from falling off during the process of the conveyor belt 2 moving the strand 4, thereby improving the stability of the conveying of the strand 4.
[0038] A second support is installed on the lower side of the conveyor belt 2. The second support is installed on the lifting platform. The lifting platform includes a hydraulic cylinder and a push rod. The push rod is connected to the second support and slides inside the hydraulic cylinder. The hydraulic cylinder pushes the push rod to move along its own axis. By setting the hydraulic cylinder, the hydraulic cylinder can push the push rod to move, thereby adjusting the height of the conveyor belt 2 so that the conveyor belt 2 can be set between the height range of the first vibration groove 1 and the second vibration groove 3, so that the strand 4 can descend in a stepped manner during the conveying process.
[0039] The second vibrating groove 3 of the present invention includes a vibrating frame and a groove body 32. The output end of the conveyor belt 2 is set on the groove body 32. The vibrating frame drives the groove body 32 to vibrate. The second vibrating groove 3 can convey the stem strips 4 and drive the stem strips 4 to move towards the stem cutting machine through vibration. During the conveying process, the stem strips can be arranged more closely, making the cutting efficiency of the cutter higher and more stem strips 4 can be cut into stem filaments.
[0040] The stalk adjustment assembly of the present invention also includes a vision sensor, which captures an image of the input port position of the channel. The excitation motor 13 can adjust its operating frequency according to the image captured by the vision sensor. The stalk adjustment assembly of the present invention is also equipped with a PLC controller. The image captured by the vision sensor is input into the PLC controller for recognition. When a stalk 4 appears to be blocked on the panel 11 in the image, the operating frequency of the excitation motor 13 can be increased to allow the stalk 4 to be dispersed and discharged. If the telescopic rod and the first support are adjusted by an electric telescopic component, the PLC controller can also adjust the tilt angle of the first vibration groove 1 to clear the blocked stalk 4. At the same time, the PLC controller can also control the rotation speed of the conveyor belt 2 and the vibration frequency of the second vibration groove 3, and thus can be linked and adjusted with the first vibration groove 1. If the tilt angle of the first vibration groove 1 is large, the rotation speed of the conveyor belt 2 is high, and the operating frequency of the second vibration groove 3 is also high, so that the conveyor belt 2 and the second vibration groove 3 can process more and more stalks 4 per unit time, and vice versa.
[0041] The present invention requires only minor modifications to the stem processing device, which can be achieved by simply adding a first vibration groove 1. At the same time, the working status of the first vibration groove 1 can be adjusted and warned in real time through a visual sensor.
[0042] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
