Description

Technical Field

[0001] This invention relates to the field of machine-made cigar roll processing technology, specifically to a vibration-leveling device for improving the quality of machine-made cigar rolls. Background Technology

[0002] Currently, the raw material supply for domestic cigar rolling machines mainly uses a conveyor belt with climbing nails. The raw tobacco sheets in the equipment's hopper are lifted and transported to the top of the belt. At the top of the belt, a rotating feed roller peels off the raw tobacco sheets. Under the action of gravity, the raw tobacco sheets slide down a smooth material chute, realizing a free-fall feeding system for the rolling machine. The material slides into the forming trough, where it is compressed and shaped by a compression mold, and then conveyed to the cigar gun to wrap the cigar sleeve. This process is closely related to the stability of the feeding flow rate and the uniformity of the feed roller. Because this feeding process uses a relatively static smooth material chute without a vibration equalization device, it is impossible to control the uniformity of the feeding, resulting in poor feeding uniformity and easy fluctuations in the quality of the rolled cigars.

[0003] When cigar tobacco raw materials enter the material chute, the sliding process is mainly driven by gravity. However, the material chute has a certain length, and the cigar tobacco raw materials themselves have a large volume. Due to their own oily characteristics and different edge curling degrees, the cigar tobacco raw materials are easy to be difficult to separate after stacking because of excessive oiliness. The curled edges and bulges can also cause congestion. Vibration transmission does not cause difficulties. These two situations do not exist in the traditional tobacco transfer process, so it is difficult to draw on the experience from tobacco transfer equipment.

[0004] Therefore, considering the characteristics of cigar tobacco raw materials, the processing of the material feeding chute stage has become a typical obstacle restricting the uniformity of tobacco distribution in the finished tobacco sticks, and a solution is urgently needed.

[0005] In order to solve the above problems, people have been seeking an ideal technological solution. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a pneumatic vibration uniform material distribution device for adjusting the uniform distribution of tobacco raw materials in a material chute to different degrees, dynamically adjusting the uniformity of tobacco raw material falling, improving the uniformity of tobacco density distribution in the forming trough, and enhancing the quality stability of machine-made cigar preforms.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is: a vibration equalization device for improving the quality of machine-made cigar tobacco blanks, comprising a material chute, a chute support frame, an elastic connector, several equalization plates, and a vibration assembly; The material chute is mounted on the chute support frame via an elastic connector, so that the entire material chute is suspended in the air. The surface of the material chute is distributed with several equalizing plates. The equalizing plates are arranged in multiple rows from the inlet side to the outlet side. The spacing between equalizing plates in the same row is equal and at least 1.5 times the width of the cigar tobacco raw material. Adjacent rows of equalizing plates are staggered in the horizontal direction to divert and equalize the cigar tobacco raw material entering the material chute. The vibration assembly is installed on the back of the material chute. The vibration assembly includes a first vibration assembly and a second vibration assembly installed at different heights on the back of the material chute. The first vibration assembly and the second vibration assembly operate at different amplitudes and vibration frequencies to drive different areas of the material chute to vibrate and homogenize the cigar tobacco raw materials. The vibration assembly is connected to the control cabinet via a control line for controlling and adjusting vibration parameters.

[0008] This invention utilizes a uniform material plate on the surface of a material chute to effectively divide and separate cigar tobacco raw materials under the flow division effect of the uniform material plate. At the same time, a vibration component is set on the back of the material chute. The entire material chute is installed on the chute support frame through elastic connectors. The vibration provides power to the cigar tobacco raw materials. On the one hand, it works with the uniform material plate to relieve and separate the clumped cigar tobacco raw materials. On the other hand, it avoids the cigar tobacco raw materials from being blocked by the uniform material plate and causing clumping. With the cooperation of the uniform material plate and the pneumatic vibration mechanism, the uniform dispersion of cigar tobacco raw materials can be achieved. Based on the above, the vibration component is a pneumatic vibration component, which includes a gas pipeline, a pneumatic control valve, and a gas source unit. The gas source unit is connected to the first vibration component and the second vibration component through the gas pipeline and two pneumatic control valves, respectively. The control cabinet adjusts the vibration frequency and vibration amplitude of the first vibration component and the second vibration component by controlling the gas source unit and the pneumatic control valves.

[0009] Based on the above, both the first vibration component and the second vibration component are eccentric vibration components. The eccentric wheel vibration mechanism includes an eccentric wheel mounting frame, an eccentric wheel, a rotating shaft, a bearing, a reciprocating linkage mechanism, and a guide sleeve. The eccentric wheel is mounted on the eccentric wheel mounting frame via the rotating shaft and the bearing. The eccentric wheel drives the output rod of the reciprocating linkage mechanism to perform linear reciprocating motion along the guide sleeve. The distal end of the output rod is fixedly connected to the back of the material chute. The driving mechanism includes a variable frequency motor, which is mounted on the eccentric wheel mounting frame or the chute support frame. The variable frequency motor drives the rotating shaft to rotate via a belt, thereby driving the eccentric wheel to rotate.

[0010] Two vibration modes are provided: pneumatic vibration and eccentric vibration. Pneumatic vibration is more effective for applications where air sources are readily available, while eccentric vibration is more adaptable.

[0011] Specifically, the two vibration components operate at different frequencies and amplitudes, and play different roles. Low-frequency vibration and small amplitude can promote the unfolding of the rolled structure of tobacco sheets to a certain extent, while high-frequency vibration and large amplitude can prevent the sticking of raw materials with high oil content.

[0012] Based on the above, the vibration frequency of the first vibration component is 10-20Hz, the vibration frequency of the second vibration component is 30Hz-50Hz, the amplitude of the first vibration component is 0.5mm-1mm, and the amplitude of the second vibration component is 1mm-2mm.

[0013] The first vibration component operates at a lower frequency and smaller amplitude, but is adjustable, and is mainly used to relieve the curled structure to a certain extent. The second vibration component operates at a higher frequency and larger amplitude to prevent the tobacco sheets from sticking together.

[0014] Based on the above, the first vibration component is located at a lower position on the back of the material chute, and the second vibration component is located at a higher position on the back of the material chute. The distance between the first vibration component and the second vibration component is between 30cm and 50cm.

[0015] This is because the material enters the chute at a relatively high speed, and the high-frequency, large-amplitude vibration rhythm can quickly separate the tobacco raw materials. After reaching a lower position, the low-frequency, small-amplitude vibration rhythm is used to gradually loosen and flatten the curled parts, eliminating the gaps and bulges between the tobacco sheets. In addition, the function of the material leveling plate further improves the material leveling efficiency.

[0016] Based on the above, both the first vibration component and the second vibration component are turbine-type pneumatic vibrators.

[0017] Based on the above, it also includes a real-time image acquisition module and a processor. The real-time image acquisition unit is used to acquire real-time distribution images of cigar tobacco raw materials on the material chute, and is used to acquire and identify two parameters: The first parameter is the edge curling condition of the cigar tobacco raw material, and the second parameter is the oiliness of the cigar tobacco raw material; The processor adjusts the vibration frequency and amplitude of the first vibration component and the second vibration component respectively based on the two identified parameters.

[0018] Based on the above, the principle for identifying the curling condition of the cigar tobacco raw material is as follows: First, the edge line of each cigar tobacco sheet is obtained by recognizing the image content. Then, the curvature of the edge line of the cigar tobacco raw material is identified, and whether it belongs to curling is determined according to the curvature of the curvature. Finally, the proportion of curling to all edge lines is counted to determine the curling condition.

[0019] Based on the above, the principle for identifying the oiliness of the cigar tobacco raw material is as follows: First, by identifying the image content, the body area of ​​each cigar tobacco is obtained. Based on the distribution area ratio and quantity of high-brightness areas in the body area and the average brightness value of these high-brightness areas, the oiliness is determined.

[0020] This solution provides a dynamic adjustment scheme that involves real-time monitoring, identification, and feedback adjustment. The identification focuses on issues such as curling edges and grease buildup. Based on the differences in these parameters, the vibration frequency and amplitude are adjusted to achieve better vibration performance.

[0021] Based on the above, the elastic connector is an elastic sheet, and a rubber shock-absorbing pad is provided between the elastic sheet and the chute support frame; a rubber shock-absorbing pad is provided between the pneumatic vibration mechanism and the material chute.

[0022] Rubber damping pads can prevent vibration and wear caused by rigid connection structures, which helps protect the structure and improve durability.

[0023] Vibration parameters can be adjusted by controlling the flow rate.

[0024] Based on the above, the front end of the uniform material plate is a triangle with rounded corners, the rear end is a rectangle, and the overall shape is similar to a boat. The front end of the uniform material plate faces the top inlet side of the material chute, and the axis of the uniform material plate is parallel to the longitudinal axis of the material chute.

[0025] In this structure, materials are more easily diverted and split, with the triangular structure at the front acting as a divider and the rectangular structure at the rear initiating a flow guiding and isolation function.

[0026] Based on the above, the material leveling plate is arranged in multiple rows from the inlet side to the outlet side, with equal spacing between the material leveling plates in the same row, and adjacent rows of material leveling plates are staggered in the horizontal direction.

[0027] In this structure, by gradually diverting and splitting the flow, the flow rates of the final output cigar tobacco raw materials are made similar to each other.

[0028] Based on the above, the uniform material plate has a thickness gradient structure with the front end thickness being less than the rear end thickness, and the front end thickness of the uniform material plate is ≤1mm.

[0029] The front end of the uniform material plate is thinner and closer to the material chute, preventing the material from being blocked by the uniform material plate.

[0030] As described above, the width of each unit of the equalizing plate changes from large to small from the inlet side to the outlet side of the material chute. This is beneficial for separating the cigar tobacco raw materials into multiple strands.

[0031] This invention has outstanding substantive features and significant progress compared to the prior art. Specifically, based on the traditional feeding system of the rolling machine, this invention improves the material chute, a weak link that interferes with the uniformity of the tobacco sheets in the product. By using a pneumatic vibration mechanism in conjunction with a uniform material plate, the distribution of tobacco sheet raw materials in the material chute can be adjusted to different degrees. This allows for dynamic adjustment of the uniformity of the tobacco sheet raw material falling, thereby improving the uniformity of the tobacco sheet density distribution in the forming trough and enhancing the stability of the tobacco sheet quality.

[0032] Because there are two vibration components, different vibration frequencies and amplitudes can be set to deal with the actual conditions of different tobacco raw materials, such as the gaps and bulges caused by curling, as well as the differences in oil content of different batches and brands of tobacco leaves, which will lead to differences in their actual distribution. Therefore, the degree of uniformity can be adjusted by fine-tuning the vibration frequency and amplitude.

[0033] Furthermore, this solution proposes using image recognition technology to monitor curling and oiliness, and then providing real-time feedback to adjust vibration parameters, thereby achieving automated adjustment capabilities for the production line.

[0034] Furthermore, since this structure can be improved based on existing material chutes without changing the original structure of the rolling mill feeding system, it has significant effects and is suitable for widespread use.

[0035] Furthermore, the two sets of vibration components drive the front and rear ends of the material chute to vibrate to different degrees, which can solve the interference problem caused by changes in the performance of the material chute itself and ensure the uniform material distribution effect.

Detailed Implementation

[0041] The technical solution of the present invention will be further described in detail below through specific embodiments. Example 1

[0042] like Figure 1 and Figure 2 As shown, a vibrating material leveling device for improving the quality of cigar tobacco blanks includes a material chute 6, a chute support frame 3, an elastic connector 12, several material leveling plates 4, a pneumatic vibration mechanism 7, and an air source unit 18.

[0043] The material chute 6 is mounted on the chute support frame 3 via an elastic connector 12. The bottom end of the chute support frame 3 is a support base 9. The bottom end of the material chute 6 is mounted on the support base 9 via the elastic connector 12, so that the material chute 6 is suspended in the air and is more easily affected by vibration.

[0044] In this embodiment, the material chute 6 is installed in the feeding system of the rolling machine. The upstream conveyor belt 1 and the feeding roller 2 work together to uniformly adjust the cigar tobacco raw material and control the flow rate of the cigar tobacco raw material entering the material chute 6 to be stable. The downstream forming groove 10 of the rolling machine is set up to press the uniformly falling cigar tobacco raw material into a roll through the mold. Therefore, maintaining the uniformity of material distribution in the material chute 6 is extremely important.

[0045] The surface of the material chute 6 is provided with several equalizing plates 4. The equalizing plates 4 are installed on the surface of the material chute 6 by first fixing bolts 5, and are used to divert and equalize the cigar tobacco raw materials entering the material chute 6.

[0046] The pneumatic vibration mechanism 7 is installed on the back of the material chute 6 by the second fixing bolt 8. The air source unit 18 is connected to the pneumatic vibration mechanism 7 through the gas pipeline 14 and the pneumatic control valve 15, so as to drive the material chute 6 to vibrate and uniformly vibrate the cigar tobacco raw material by the pneumatic vibration mechanism 7.

[0047] The air source unit 18, pneumatic control valve 15, and pneumatic vibration mechanism 7 are connected to the control cabinet 17 via control line 16 for controlling and adjusting vibration parameters.

[0048] To ensure the reliability and flexibility of the vibration, in this embodiment, the pneumatic vibration mechanism 7 includes a first vibration component 78 and a second vibration component 79 installed at different heights on the back of the material chute. The air source unit 18 is connected to the first vibration component 78 and the second vibration component 79 through the gas pipeline 14 and the pneumatic control valve 15, respectively, so as to drive the upper and lower parts of the material chute 6 to vibrate and evenly distribute the cigar tobacco raw materials. In this embodiment, the first vibration component 78 and the second vibration component 79 are turbine-type pneumatic vibrators. In other embodiments, they can also be common pneumatic vibration products such as pneumatic linear vibrators.

[0049] The second vibration component 79 is located at a higher position on the back of the material chute, and the interval between the first vibration component 78 and the second vibration component 79 is between 30cm and 50cm. The first vibration component 78 and the second vibration component 79 operate at different vibration frequencies and amplitudes. Specifically, the vibration frequency of the first vibration component 78 is 10-20Hz, the vibration frequency of the second vibration component 79 is 30Hz-50Hz, the amplitude of the first vibration component 78 is 0.5mm-1mm, and the amplitude of the second vibration component 79 is 1mm-2mm.

[0050] Technical principle: After being processed by the conveyor belt 1 and the feeding roller 2, the cigar tobacco raw materials are sent to the inlet end of the material chute 6. Under the action of initial speed and its own weight, the cigar tobacco raw materials slide down the material chute 6 towards the outlet side. The initial speed when entering the material chute 6 is relatively fast. During the sliding process, due to the large volume of the cigar tobacco raw materials and the different oil content resulting in different viscosity, they may overlap or entangle with each other. After falling into the material chute 6, due to the problem of curled edges, it is easy to cause bulging and lifting when stacking, which is not conducive to the transmission of vibration and affects the uniformity of distribution.

[0051] To address the aforementioned issues, in the case of rapid initial entry into the material chute, the high-frequency, large-amplitude vibration of the second vibration component can quickly separate the tobacco sheet raw materials. Once they reach a lower position, the low-frequency, small-amplitude vibration of the first vibration component gradually loosens and flattens the curled parts, eliminating issues such as gaps or bulges between the tobacco sheets and significantly improving the material uniformity.

[0052] The first vibration component operates at a lower frequency and smaller amplitude, but is adjustable, and is mainly used to relieve the curled structure to a certain extent. The second vibration component operates at a higher frequency and larger amplitude to prevent the tobacco sheets from sticking together.

[0053] Meanwhile, a uniform material plate 4 is distributed in the material chute 6, and the cigar tobacco raw material is distributed step by step by the diversion function, which effectively avoids material swarming and makes the cigar tobacco raw material in the final output material chute 6 evenly distributed.

[0054] In terms of the power of circulation, in the traditional solution, the material chute has a certain length, and the sliding process mainly relies on the weight of the cigar tobacco raw material and the initial power provided by the upstream feeding roller. There is no power intervention during the sliding process. This embodiment provides a two-stage vibration component, one in front and one in back, to apply vibration to the front and rear ends of the material chute respectively, and also has the function of providing the driving power.

[0055] When there is no need to consider issues such as curling or oiliness, in terms of speed control, taking different situations as examples, if the downward speed of the cigar tobacco raw material in the latter part slows down significantly, the vibration frequency and amplitude of the first vibration component 78 can be appropriately increased to give the cigar tobacco raw material more sufficient vibration power so that it can descend quickly. At this time, the second vibration component 79 mainly cooperates with the parameters of the first vibration component 78 to adjust the output speed and flow rate. If the downward speed of the cigar tobacco raw material in the front section slows down significantly, the vibration frequency and amplitude of the second vibration component 72 can be appropriately increased to avoid the cigar tobacco raw material from accumulating in a localized area due to the speed difference between the front and rear sections.

[0056] The states shown in the examples above are dynamically changing according to the actual situation. The observation and control of these states can be done manually or automatically with the help of currently popular visual recognition systems.

[0057] In terms of specific control methods, in this embodiment, the control cabinet is connected to a pneumatic control valve to regulate the flow rate; the air source unit is equipped with a flow control unit to adjust the total air flow rate.

[0058] Due to structural interference caused by vibration, in a preferred embodiment, the elastic connector 12 is an elastic sheet, and a rubber shock-absorbing pad is provided between the elastic sheet and the slide support frame 3; a rubber shock-absorbing pad is provided between the pneumatic vibration mechanism 7 and the material slide 6 to provide a damping effect, which can avoid vibration wear caused by rigid connection structure, which is beneficial to protect the structure and improve durability.

[0059] Vibration parameters can be adjusted by controlling the flow rate.

[0060] The front end of the uniform material plate 4 is a triangle with rounded corners, and the rear end is a rectangle, with an overall shape similar to a boat. The front end of the uniform material plate 4 faces the top inlet side of the material chute 6, and the axis of the uniform material plate 4 is parallel to the longitudinal axis of the material chute 6.

[0061] This embodiment provides a parameter example for illustration, specifically, as follows: Figure 3 As shown, the top of the uniform material plate 4 is an arc angle with an angle θ=25°, the length of the triangle L1=15mm, and the length of the rectangle L2=30mm; the maximum width of the uniform material plate 4 is L3=15mm, the maximum thickness (tail end thickness) H1=10mm, and the minimum thickness (front end thickness) H2=1mm.

[0062] In this structure, the material is more easily diverted and split. The triangular structure at the front acts as a divider, while the rectangular structure at the rear acts as a guide and isolation mechanism. The front end of the uniform material plate 4 is thinner and closer to the material chute, preventing the material from being blocked by the uniform material plate.

[0063] In this embodiment, the equalizing plates 4 are arranged in multiple rows from the inlet side to the outlet side, with equal spacing between equalizing plates 4 in the same row, and adjacent rows of equalizing plates 4 are staggered in the horizontal direction. Under this structure, through step-by-step diversion and splitting, the flow rates of the final output cigar tobacco raw materials are made approximately similar to each other. Example 2

[0064] When it is necessary to improve the level of automation and intelligence, the significant difference between this embodiment and Embodiment 1 is that it also includes a real-time image acquisition module and a processor. The real-time image acquisition unit is used to acquire real-time distribution images of cigar tobacco raw materials on the material chute, and is used to acquire and identify two parameters: The first parameter is the edge curling condition of the cigar tobacco raw material, and the second parameter is the oiliness of the cigar tobacco raw material; The processor adjusts the vibration frequency and amplitude of the first vibration component and the second vibration component respectively based on the two identified parameters.

[0065] Specifically, the principle for identifying the curling condition of the cigar tobacco raw material is as follows: First, the edge line of each cigar tobacco sheet is obtained by recognizing the image content. Then, the curvature of the edge line of the cigar tobacco raw material is identified, and whether it belongs to curling is determined according to the curvature of the curvature. Finally, the proportion of curling to all edge lines is counted to determine the curling condition.

[0066] This is because the raw materials for cigar tobacco are relatively large in volume and have clear boundary structures, making it relatively easy to identify the edge positions. By counting the number of boundary lines, the approximate quantity of raw materials for cigar tobacco can be determined. Then, based on the direction of the cigar's edge lines, it can be determined whether there is any curling. This identification relies entirely on the judgment of the line shape. It can be done by relying on algorithms or by setting up a corresponding identification model and applying it after training.

[0067] Based on the above, the principle for identifying the oiliness of the cigar tobacco raw material is as follows: First, by identifying the image content, the body area of ​​each cigar tobacco is obtained. Based on the distribution area ratio and quantity of high-brightness areas in the body area and the average brightness value of these high-brightness areas, the oiliness is determined.

[0068] This is because the oiliness parameters of cigar tobacco raw materials vary in different batches and brands. Oiliness is reflected in the image as a glossy sheen. The lighting environment inside the factory is relatively stable. By collecting the number and area ratio of reflective points, the approximate range of oiliness can be determined. By calculating the average value of the brightness, the specific parameter range of oiliness can be further determined.

[0069] Since this method is not used to detect specific oiliness parameters, it does not require specialized spectroscopic equipment for professional data acquisition and calculation. It only needs to make a general judgment on the oiliness. Therefore, it uses relatively obvious reflective properties to solve this problem, which is simpler than the spectral principle and does not require additional equipment investment, resulting in relatively low modification costs.

[0070] This solution provides a dynamic adjustment scheme that involves real-time monitoring, identification, and feedback adjustment. The identification focuses on issues such as curling edges and grease buildup. Based on the differences in these parameters, the vibration frequency and amplitude are adjusted to achieve better vibration performance. Example 3

[0071] The difference between this embodiment and embodiments 1 and 2 is that: Figure 4 As shown, both the first and second vibration components are eccentric vibration components. The eccentric vibration component 7 includes an eccentric wheel mounting frame 71, an eccentric wheel 72, a rotating shaft 73, a bearing 74, a reciprocating linkage mechanism 75, and a guide sleeve 76. The eccentric wheel 72 is mounted on the eccentric wheel mounting frame 71 via the rotating shaft 73 and the bearing 74. The eccentric wheel 72 drives the output rod 77 of the reciprocating linkage mechanism 75 to perform linear reciprocating motion along the guide sleeve 76. The distal end of the output rod 77 is fixedly connected to the back of the material chute 6. The driving mechanism includes a variable frequency motor 10, which is mounted on the eccentric wheel mounting frame 71 or the chute support frame 3. The variable frequency motor 10 drives the rotating shaft to rotate via a belt, thereby driving the eccentric wheel to rotate.

[0072] In this invention, both the eccentric wheel mounting bracket 71 and the guide sleeve 76 are fixed based on additional mounting brackets. The main purpose of this solution is based on the ease of modification. Since the traditional material chute is a complete structural component, maintaining its integrity is a challenge when modifying it. This invention uses an eccentric wheel vibration mechanism to drive the material chute to vibrate. Only one set of eccentric wheel vibration mechanisms needs to be installed on the back of the original material chute, and the output rod is fixed to the back of the material chute. This can drive the material chute to reciprocate without making major changes to the structure of the material chute.

[0073] The control cabinet adjusts the vibration frequency of the eccentric wheel vibration mechanism by controlling the operating frequency of the variable frequency motor. Using a variable frequency motor allows for flexible changes in the drive frequency, thereby altering the vibration frequency of the eccentric wheel vibration mechanism, resulting in greater vibration flexibility.

[0074] In a more preferred embodiment, the eccentricity of the eccentric wheel in the eccentric wheel vibration mechanism is adjustable. The eccentric wheel is a detachable structure to facilitate maintenance and replacement of eccentric wheels with different parameters.

[0075] 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.
