Description

A method for homogenizing and quantitatively feeding materials to improve the quality stability of machine-made cigar roll blanks. Technical Field

[0001] This invention relates to the field of machine-made cigar roll processing technology, specifically, to a method for uniform and quantitative feeding of materials to improve the quality stability of machine-made cigar rolls. Background Technology

[0002] Currently, the supply of fillers for domestic machine-made cigar rolls mainly involves using a feeding roller to transfer the filler material from the hopper to the filler material chute. Under the action of gravity, the filler slides down the smooth surface of the chute, realizing a free-fall feeding system for the roll machine. After sliding down, the filler combines with materials such as the cigar binder (or cigarette paper), and after pasting and shaping, forms the machine-made cigar roll.

[0003] Utility model patent CN 206590535 U discloses a material feeding limiting device for a cigar roll machine. It uses a limiting roller and a feeding roller at the top of the conveyor belt to feed the material, thereby stabilizing the material flow and solving the problem of fluctuating cigar filler flow to a certain extent.

[0004] However, due to the characteristics of the filler (cigar sheets have a certain size) and the amount of material in the hopper, it is impossible to effectively control the actual amount of filler material falling and the uniformity of axial distribution. This results in uneven distribution of the filler in the cigarette blank, forming defective cigarettes such as those that are too loose or too tight, or have bamboo-like joints. This causes problems such as large fluctuations in the quality of machine-made cigar roll blanks and poor quality stability between batches.

[0005] For the reasons mentioned above, the groove section of the eggplant core has become the bottleneck restricting the uniformity of eggplant core rolling. How to overcome this problem is a core issue that urgently needs to be solved by those skilled in the art.

[0006] In order to solve the above problems, people have been seeking an ideal technological solution. Summary of the Invention

[0007] The purpose of this invention is to address the shortcomings of existing technologies by providing a uniform and quantitative feeding method for improving the quality stability of machine-made cigar roll blanks. This method involves adding a relief and dispersion action to fully disperse the cigar filler material as it passes through a chute, followed by a temporary storage action to temporarily store a certain amount of the cigar filler material. This ensures the consistency of the output cigar filler material quality and makes it easier to match with downstream rolling equipment.

[0008] To achieve the above objectives, the technical solution adopted by this invention is: a method for uniform and quantitative feeding to improve the quality stability of machine-made cigar roll blanks, comprising the following steps: S1: The filler material is drawn from the hopper or the incoming conveyor belt by a feeding roller and delivered to the upper inlet of the chute. The filler material slides down the surface of the chute under the action of gravity; S2: In the first stage of sliding, the filler material in the sliding state is relaxed and dispersed so that the filler material is evenly distributed in the chute in the transverse direction; S3: In the second stage of sliding, the filler material in the sliding state is intercepted and retained. After a set amount or a set time has elapsed, the retained filler material is released all at once; S4: The released filler material enters the shaping equipment below to complete the quantitative feeding; the actions of S1 and S2 are continuous actions, and the action of S3 is an intermittent action. The frequency of interception and release in S3 is set to be consistent with the rolling frequency of the downstream rolling equipment.

[0009] This invention addresses a weakness in the existing cigar filler rolling process – the chute section – by breaking down the initial free-falling motion into two stages. The first stage loosens and disperses the filler material, ensuring more even distribution, especially laterally, during the fall. The second stage uses interception and temporary storage to retain and accumulate the filler material, eliminating uneven distribution over a certain period. Finally, a single feeding process delivers the filler material into the downstream shaping equipment, achieving quantitative feeding. Essentially, this invention shortens the length of the filler material's free fall through the chute. By segmenting and controlling the cycle time, the filler material is supplied intermittently in segments, mitigating the uneven distribution caused by continuous falling material.

[0010] Based on the above, in step S2, the method for dispersing and dispersing the eggplant core material is as follows: at least one rake roller is installed at a set height position above the chute, and rake nails are installed on the surface of the rake roller. The rotation of the rake roller drives the rake nails to disperse and disperse the eggplant core material passing through, thereby achieving uniform material distribution.

[0011] Its advantage lies in the fact that the filler material is different from ordinary tobacco. It has a certain volume and may cause mutual interference. By using rakes to loosen and disperse the filler material along the way, interference between the filler materials can be avoided.

[0012] Based on the above, the rotation direction of the rake roller is opposite to the flow direction of the eggplant core raw material.

[0013] By using reverse roller motion, a localized opposing pulling action is generated with the eggplant core material, thereby separating the eggplant core material.

[0014] Based on the above, the rake spikes are spirally distributed along the length of the rake roller. Its advantage lies in its ability to disrupt and interfere with the flow of eggplant core raw materials, thereby redistributing their sliding rhythm to a certain extent.

[0015] Based on the above, in step S3, the method for intercepting and retaining the eggplant core raw material is as follows: a feeding bin is set up on the surface of the chute. The top inlet and bottom outlet of the feeding bin can be opened and closed. By controlling the opening and closing of the feeding bin's inlet and outlet, the eggplant core raw material can be intercepted, retained, or released.

[0016] This method allows for the quantitative temporary storage of eggplant core raw materials.

[0017] Based on the above, in step S3, the method for determining whether the eggplant core material has reached the set amount is as follows: a through-beam sensor is installed at a set height to monitor the material level of the eggplant core material remaining in the feeding hopper, in order to determine whether the set amount has been reached. By detecting the material level height, the remaining amount is determined, and then it is determined whether the set weight has been reached.

[0018] Based on the above, in step S3, the method for determining whether the eggplant core raw material has reached the set amount is as follows: a weighing sensor is integrated into the door panel at the bottom outlet of the feeding hopper, and the set amount is determined based on the real-time detection of weight data. This method is more direct, using weighing to determine whether the set amount has been reached.

[0019] Based on the above, in step S3, the method for determining the retention time is as follows: a timer is set for the inlet and outlet actions of the feeding hopper, and the inlet and outlet action time of the feeding hopper is determined according to the timer. This method utilizes the stable inflow rate of the eggplant core raw material at the front end, which allows for the calculation and determination of the storage time, thereby achieving stable storage.

[0020] Based on the above, a residual material recovery trough is also provided for the feeding bin. The residual material recovery trough is inclined outside the outer wall of the feeding bin, and the outlet end of the residual material recovery trough extends outside the chute. The top inlet side of the feeding bin forms a slope towards the residual material recovery trough after it is closed. When the feeding bin is closed, the residual material flows to the residual material recovery trough and is discharged outside the chute.

[0021] When the feed hopper is closed, the upstream material supply is uninterrupted, so excess raw materials can be recycled, which avoids waste and also avoids affecting the downstream material storage process.

[0022] Based on the above, the length, width, and height parameters of the feeding bin are greater than those of the downstream shaping equipment's hopper. This is to meet the production needs of machine-made cigars of different specifications and improve adaptability.

[0023] This invention has outstanding substantive features and significant progress compared to the prior art. Specifically, this invention disassembles and processes the process of the cigar filler material freely sliding down the chute in a segmented manner. In the first stage of sliding, the filler material is loosened and dispersed to ensure that it is evenly distributed in the lateral direction of the chute. In the second stage of sliding, the filler material is intercepted and temporarily stored. The amount of temporary storage is determined by controlling the parameters of interception and release. This intermittent release method eliminates the interference caused by uneven distribution of the filler material. After two stages of processing, the quality stability of the filler material entering the downstream rolling equipment is improved, quantitative feeding is achieved, and the consistency and stability of the machine-made cigar roll blanks are improved.

[0024] Furthermore, by setting up a waste material recycling tank, excess materials can be recycled, improving utilization rate and reducing the probability of excess materials entering downstream winding equipment, thus ensuring winding consistency and stability.

[0025] Furthermore, the working frequency of the first stage of relief and dispersion, as well as the opening and closing frequency of the feeding hopper in the second stage, are controllable and adjustable to adapt to the working frequency of the upstream and downstream processes, thereby maintaining the matching degree of the processing speed of the machine-made cigar roll blank machine.

[0026] Furthermore, the specifications of the feeding hopper can be customized according to the specifications of the downstream shaping equipment, thus improving the adaptability of the equipment. Attached Figure Description

[0032] The technical solution of the present invention will be further described in detail below through specific embodiments.

[0033] As shown in Figures 1-4, a method for uniform feeding and quantitative feeding to improve the quality stability of machine-made cigar roll blanks includes the following steps: S1: The filler material is pushed out from the hopper or the incoming conveyor belt by the feeding roller and delivered to the upper inlet of the chute 1. The filler material slides down the surface of the chute 1 under the action of gravity. The chute 1 is inclined as a whole. In the traditional solution, the filler material slides freely under its own weight.

[0034] S2: In the first stage of the sliding process, the eggplant core material in the sliding state is loosened and dispersed, so that the eggplant core material is evenly distributed in the chute in the transverse direction. Specifically, in this embodiment, at least one rake roller 2 is installed at a set height above the chute 1. Rake nails 3 are installed on the surface of the rake roller 2. The rotation of the rake roller 2 drives the rake nails 3 to loosen and disperse the eggplant core material passing through, so as to achieve uniform material distribution. The rake roller 2 is driven to rotate by a rake roller motor 4. Its rotation direction can be either forward or reverse. In this embodiment, it is driven to rotate in the opposite direction to the flow direction of the eggplant core material, so as to generate an interaction force with the eggplant core material locally and ensure the dispersion of the eggplant core material.

[0035] In this embodiment, the rake roller 2 is installed in the upper part of the chute 1 to loosen and disperse the eggplant core raw materials before they affect each other and clump together, so as to avoid them being difficult to loosen after clumping or remaining in the same position after loosening.

[0036] The rotation speed of the rake roller 2 is adjustable. The adjustment is based on the processing speed of the cigar roll blank machine to ensure uniform material distribution.

[0037] In a preferred embodiment, the rake spikes are spirally distributed along the length of the rake roller. This has the advantage of disrupting and interfering with the flow of eggplant core material, redistributing its sliding rhythm to some extent. Furthermore, the spiral rake spikes, while rotating, possess a certain horizontal pushing ability, which can disperse excess material horizontally to a certain extent.

[0038] S3: In the second stage of the slide, the eggplant core material in the slide state is intercepted and retained. After the retained amount reaches a set amount or after a set time, the retained eggplant core material is released all at once.

[0039] In this embodiment, the method for intercepting and retaining the eggplant core raw material is as follows: a feeding bin 5 is set on the surface of the chute 1. The top inlet and bottom outlet of the feeding bin 5 can be opened and closed, which are respectively an inlet baffle 6 and an outlet baffle 7. The inlet baffle 6 is controlled by an inlet drive mechanism 8, and the outlet baffle 7 is controlled by an outlet drive mechanism 9. Both the inlet drive mechanism 8 and the outlet drive mechanism 9 are cylinders. In other embodiments, electric cylinders, electrically controlled telescopic rods, or hydraulic telescopic rods can also be used. By controlling the opening and closing of the inlet and outlet of the feeding bin 5, the interception, retention, or release of the eggplant core raw material can be achieved.

[0040] Since the main purpose of temporary storage is to control the quality and uniformity of the blank produced by the downstream rolling equipment in a single roll, certain means are needed to control the inlet and outlet of the feed bin 5.

[0041] In this embodiment, the length, width, and height parameters of the feeding bin 5 are greater than those of the downstream shaping equipment bin, to meet the production needs of different specifications of machine-made cigars and improve adaptability. Therefore, when the feeding bin is full, it can be determined that the amount of material stored is up to standard. By controlling the inlet baffle 6 to close the feeding bin 5, excess material can be discharged, thus achieving quantitative feeding. Essentially, this is achieved by controlling time, using hardware devices such as timers, i.e., controlling the opening and closing rhythm, thus realizing this function.

[0042] In this embodiment, the length, width, and height of the hopper in the production process of a certain specification of machine-made cigar are set to 120mm*8.9mm*8.9mm; the length, width, and height of the hopper in the production process of a certain specification of machine-made cigar are 84mm*9.5mm*9.5mm.

[0043] In terms of cycle time setting, the inlet drive mechanism 8 and the outlet drive mechanism 9 can control the orderly opening and closing of the inlet baffle 6 and the outlet baffle 7 of the feed bin 5 according to the production efficiency, matching the processing speed of the machine-made cigar roller. For example, if the rolling efficiency of a certain brand of machine-made cigars is 30 cigars / minute, the opening frequency of the quantitative feeding cylinder is set to 30 times / minute to meet the requirements of machine-made cigar rolling.

[0044] In other embodiments, a through-beam sensor is installed at a set height to monitor the level of the eggplant core material remaining in the feeding hopper, in order to determine whether the set amount has been reached. By detecting the material level height, the remaining amount is determined, and then it is determined whether the set weight has been reached.

[0045] In another embodiment, a weighing sensor is integrated into the door panel at the bottom outlet of the feeding hopper to determine whether the set amount has been reached based on real-time detection of weight data. This method is more direct, using weighing to determine whether the set amount has been reached.

[0046] S4: The released cigar filler material enters the shaping equipment below, where quantitative feeding is completed. The shaping equipment, together with the cigar binder or cigarette paper, forms a machine-made cigar blank after pasting and shaping.

[0047] S1 and S2 are continuous actions, while S3 is an intermittent action. The frequency of interception and release in S3 is set to be consistent with the winding frequency of the downstream winding equipment.

[0048] In more embodiments, a residual material recovery trough 10 is also provided for the feeding bin. The residual material recovery trough 10 is inclined outside the outer wall of the feeding bin 5. The outlet end of the residual material recovery trough 10 extends beyond the chute 1. After the feeding bin 5 is closed, the top inlet side forms a slope 11 that is inclined towards the residual material recovery trough 10. When the feeding bin 5 is closed, the residual material flows to the residual material recovery trough 10 and is discharged outside the chute 1. It can be temporarily received by the transfer equipment and periodically stored in the raw material bin for reuse.

[0049] When the feed hopper is closed, the upstream material supply is uninterrupted, so excess raw materials can be recycled, which avoids waste and also avoids affecting the downstream material storage process.

[0050] This invention discloses a method for uniform and quantitative feeding to improve the quality stability of machine-made cigar rolls. A rake roller 2 is installed on a chute 1, and a feeding bin 5 is set up for temporary storage and quantitative feeding of cigar filler material. This achieves uniform and quantitative feeding of cigar filler material during the rolling process, ensuring the stability and consistency of the cigar roll quality. Excess filler material can also be recovered, improving material utilization. Furthermore, quantitative feeding bins for different specifications of machine-made cigars can be set up to accommodate the required filler quantity, improving equipment applicability. Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this invention and not to limit it. Although the 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 invention or equivalent substitutions can be made to some technical features without departing from the spirit of the invention, and all such modifications should be covered within the scope of the technical solution claimed in this invention.
