Description

Technical Field

[0001] The invention relates to the technical field of shredded tobacco selection and separation, in particular to an online shredded stem selection and separation device for a cigarette making machine. Background Art

[0002] When producing and processing tobacco, it is generally necessary to cut tobacco leaves into filaments. Tobacco leaves contain main vein tobacco stems and a large number of side vein tobacco stems. The presence of tobacco stems not only affects its taste, but also punctures the cigarette wrapping paper, affecting the quality of the cigarette. Therefore, when processing filamentous tobacco, it is necessary to select and separate the tobacco. After searching, the Chinese invention patent with publication number CN115669989B discloses an online tobacco stem selection and separation device for cigarette making machines. The small amount of stems contained in the fallen stems are blown into the separation bin through horizontal airflow. The stems fall into the spiral conveying mechanism of the stems below due to gravity. The stems in the separation bin are usually of high purity and are sent to the cigarette making machine through the tobacco conveying pipeline to participate in the cigarette making operation. The separated stems are not pure enough and continue to enter the secondary stem separation mechanism for separation.

[0003] In the related art, when tobacco leaves are switched to shredded tobacco, the shredded tobacco is easily entangled together and formed into a mass, which affects the subsequent selection and separation work; when the above-mentioned shredded tobacco selection and separation device is in operation, the shredded tobacco in a mass is separated by the shredded tobacco separation mechanism, and then the separated shredded tobacco is selected and separated by the stem and stick separation mechanism. However, when the device separates the stem and stick by air selection, it only has a single air selection and separation work. Because tobacco leaves are prone to different specific gravities when they are cut into shreds, it is impossible to air select shredded tobacco with different specific gravities by a single air selection and separation method, resulting in a large amount of shredded tobacco in the separated stem and stick, and the selection and separation effect is not good. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the present invention provides an online shredded tobacco selecting and separating device for a cigarette making machine. A plurality of air selection components and air blowing components are sequentially arranged from top to bottom inside a shell body, so that the shredded tobacco can be subjected to multi-stage air selection and separation treatment, thereby realizing initial air selection, mid-term air selection and final air selection of the shredded tobacco. The device has a multi-level selecting and separating function, which further improves the selecting and separating effect of the shredded tobacco, and solves the problem that the selecting and separating devices in the prior art generally only have a single air selection and separation function. If the shredded tobacco is not thoroughly dispersed in the early stage, it will not be easy for the shredded tobacco to be separated from the total stem during air selection and separation, resulting in a large amount of shredded tobacco contained in the subsequent stems, thereby reducing the selecting and separating effect of the shredded tobacco.

[0020] (III) Beneficial effects

[0021] Compared with the prior art, the present invention provides an online shredded stem selection and separation device for a cigarette making machine, which has the following beneficial effects:

[0022] 1. The present invention has a plurality of air selection components and air blast components arranged in sequence from top to bottom inside the shell, so that the tobacco can be subjected to multi-stage air selection and separation treatment, and the initial air selection, mid-term air selection and final air selection of the tobacco can be realized. The invention has a multi-level selection and separation function, and the selection and separation effect of the tobacco is further improved. The selected tobacco after air selection and separation can be received by the setting of the pad, and the position of the pad can be adjusted horizontally by the setting of the adjusting part, so as to meet the receiving work of selected tobacco of different specific gravities, and solves the problem that the selection and separation device in the prior art generally only has a single air selection and separation function. If the tobacco is not dispersed thoroughly in the early stage, it will not be easy for the tobacco to be separated from the total stem during air selection and separation, resulting in a large amount of tobacco in the subsequent stem, which reduces the selection and separation effect of the tobacco.

[0023] 2. The present invention can spray the airflow at the temple of the blower frame in a horizontal straight line through a row of separation air flow holes opened on one side of the blower frame, so as to blow the tobacco shreds that slide downward. Since the weight of the stems is greater than the weight of the tobacco, the blowing distance of the tobacco shreds is greater than the distance of the stems, and the pad in the air selection component is cooperated to receive the selected and separated tobacco. A row of upwardly inclined boiling air flow holes is opened on one side of the blower frame, so as to blow the tobacco shreds that slide downward upward, so as to boil the tobacco shreds that slide downward in the air to form a dispersed treatment, thereby increasing the separation effect of the separation air flow holes on the selection and separation of tobacco, thereby solving the problem that the blower mechanism in the prior art generally only has the horizontal spraying operation and lacks the function of boiling and dispersing the tobacco shreds before selection.

[0024] 3. The present invention can drive the rake frame to move forward and backward by driving the sliding frame forward and backward through the driving member. The rake frame can be used to disperse the tobacco concentrated in the middle part of the conveyor belt on both sides through the forward and backward movement of the rake frame, thereby improving the effect of subsequent air separation. The rake frame can fully disperse the tobacco gathered in the middle part through the forward and backward movement of the rake frame in conjunction with the rotating conveying of the conveyor belt, thereby solving the problem that the existing separation device cannot completely separate the clumped tobacco, thereby affecting the separation effect of the tobacco stems and sticks during the subsequent air separation.

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.

[0043] Embodiment 1:

[0044] See attached Figure 1-10, an online shredded tobacco separation device for a cigarette making machine, comprising a dispersing mechanism for dispersing shredded tobacco after shredding and a separating mechanism for sorting the shredded tobacco after dispersion, the separating mechanism comprising an inclined shell 1, and a shredded tobacco inlet, a shredded tobacco outlet and a shredded tobacco outlet are respectively arranged at the top and the bottom of the shell 1, a plurality of air separation components 2 are sequentially arranged from top to bottom inside the shell 1, and the plurality of air separation components 2 are arranged in an inclined shape, and a blasting component 3 for blowing air into the shell 1 is arranged on one side of the shell 1;

[0045] By sequentially arranging a plurality of air separation components 2 and air blast components 3 from top to bottom inside the housing 1, the tobacco can be subjected to multi-stage air separation and treatment, realizing the initial air separation, mid-term air separation and final air separation of the tobacco, having a multi-level selection and separation function, further improving the tobacco selection and separation effect, and solving the problem that the selection and separation device in the prior art generally only has a single air separation and separation function, if the tobacco is not thoroughly dispersed in the early stage, it will not be easy for the tobacco to be separated from the total stem during air separation, resulting in a large amount of tobacco in the subsequent stem, which reduces the tobacco selection and separation effect;

[0046] The wind selection assembly 2 includes a backing plate 21, a tobacco guide plate 22 and a stem guide plate 23 arranged inside the housing 1. The tobacco guide plate 22 and the stem guide plate 23 are both located at the bottom of the backing plate 21, and the tobacco guide plate 22 and the stem guide plate 23 are installed in a symmetrical and inclined manner. A filter mesh hole 24 is opened on the other side of the housing 1;

[0047] The setting of the pad 21 can receive the selected tobacco after air selection and separation, and the selected tobacco and separated stems can be guided downward in sequence through the tobacco guide plate 22 and the stem guide plate 23. The setting of the filter mesh 24 is used to guide the gas after air selection and separation in an orderly manner, further improving the guiding effect of the selected tobacco.

[0048] An adjusting member 25 for adjusting the level of the pad 21 is provided inside the housing 1;

[0049] By setting the adjusting member 25, the position of the pad 21 can be adjusted horizontally, thereby meeting the requirements for receiving selected shredded tobacco with different specific gravities.

[0050] Refer to the attached Figure 2 , Figure 4 and Figure 5 The adjusting member 25 includes two guide rail frames 251 fixed inside the housing 1, and the pad 21 slides inside the two guide rail frames 251;

[0051] The two guide rail frames 251 are provided to facilitate the backing plate 21 to be installed inside the housing 1 in a sliding manner. By adjusting the position of the backing plate 21, selected tobacco with different specific gravities can be received.

[0052] An adjustment plate 252 is slidably connected to one side of the inner wall of the housing 1 in an up-and-down sliding manner. The adjustment plate 252 is hinged to one side of the backing plate 21 through two inclined adjustment frames 253. A screw rod 254 for adjusting the adjustment plate 252 up and down is threadedly connected to the other side of the housing 1, and the bottom end of the screw rod 254 is rotatably connected to the top of the adjustment plate 252.

[0053] By manually rotating the screw rod 254, the adjustment plate 252 can be driven to move up and down, and the up and down movement of the adjustment plate 252 can drive the two inclined adjustment frames 253 to move in a fan shape, and then drive the pad 21 to move horizontally, so as to adjust the distance between the pad 21 and the blowing end of the blowing assembly 3, and realize the reception of selected tobacco with different specific gravities, further improve the tobacco stem removal and air selection effect, and solve the problem that when air separation is performed on tobacco with different specific gravities, the pad 21 is not easy to receive the selected tobacco when the air flow is in a fixed state due to the large specific gravity of the tobacco;

[0054] The invention also solves the problem that, due to the small specific gravity of tobacco shreds and when the airflow is in a fixed state, the pad 21 receives too much selected tobacco shreds, resulting in receiving a part of the stems and affecting the air separation effect.

[0055] See attached Figure 3 , Figure 4 and Figure 6 The air blowing assembly 3 includes a plurality of air blowing frames 31 and a blower 32 for inputting gas into the plurality of air blowing frames 31. One side of the housing 1 is fixedly connected with a plurality of mounting frames 33. The plurality of air blowing frames 31 are detachably mounted inside the plurality of mounting frames 33.

[0056] A plurality of mounting frames 33 are fixedly connected through one side of the shell 1, and the blower frame 31 is detachably mounted inside the mounting frame 33, thereby facilitating the disassembly of the blower frame 31, thereby realizing the subsequent inspection, maintenance and replacement of the blower frame 31, and facilitating the later staff to inspect and maintain the air selection component 2 inside the shell 1 through the position of the mounting frame 33.

[0057] See attached Figure 3 , Figure 4 and Figure 6 The blower 32 is fixedly connected to a gas main pipe 34, and the gas main pipe 34 is fixedly connected to a plurality of drainage pipes 35, one end of each of the plurality of drainage pipes 35 is fixedly connected to the inside of each of the plurality of blast frames 31, and each of the plurality of drainage pipes 35 is provided with a valve member 36;

[0058] The blower 32 is connected to an external power source and a control switch, and is used to inject air into the interior of the plurality of blower frames 31 through the gas main pipe 34 and the plurality of drainage pipes 35, so as to form a tobacco wind separation operation;

[0059] The valve member 36 is used to control the gas flow rate entering the blast frame 31 through the drainage pipe 35, which not only satisfies the air separation work of tobacco with different specific gravities, but also satisfies the air separation strength of the air separation components 2 at different positions from top to bottom, thereby forming the initial air separation, mid-term air separation and final air separation work of tobacco.

[0060] The gas flow entering the blast frame 31 through the drainage pipe 35 is controlled to facilitate the adjustment of the position of the pad 21 in the air selection component 2, thereby meeting the requirements for the separation of tobacco shreds with different specific gravities;

[0061] The valve member 36 is an electric valve or a manual valve used in the prior art to control the drainage tube 35;

[0062] A row of boiling air holes 37 and a row of separation air holes 38 are sequentially provided on one side of the blast frame 31 from top to bottom, and the outlets of the row of boiling air holes 37 are arranged in an upwardly inclined manner;

[0063] Through a row of separation airflow holes 38 opened on one side of the blast frame 31, the airflow at the temple of the blast frame 31 can be sprayed horizontally and linearly, so as to blow the tobacco shreds sliding downward. Since the weight of the stems is greater than the weight of the tobacco shreds, the blowing distance of the tobacco shreds is greater than the distance of the stems, and the pad 21 in the air selection component 2 is used to receive the selected and separated tobacco shreds.

[0064] A row of upwardly inclined boiling air flow holes 37 are provided on one side of the blast frame 31, so that the tobacco shreds sliding downward can be blown upwardly, and then the tobacco shreds sliding downward can be boiled in the air to form a dispersion treatment, thereby increasing the selection and separation effect of the separation air flow holes 38 on the tobacco shreds, solving the problem that the blast mechanism in the prior art generally only has horizontal injection operation and lacks the function of boiling and dispersing the tobacco shreds before selection.

[0065] Refer to the attached Figure 1 and Figures 7 to 10 The dispersing mechanism includes a conveying frame 4, a conveying belt 5 arranged inside the conveying frame 4, two driving rollers for rotating the conveying belt 5, and a driving motor 6 for rotating one of the driving rollers. A guide plate 7 for discharging the tobacco on the conveying belt 5 to the inside of the tobacco inlet is fixedly connected to one side of the bottom of the conveying frame 4;

[0066] The driving motor 6 is connected to an external power supply and a control switch, and is an electric motor with adjustable speed. It is set up using the connection method and encoding method of the prior art, and is used to drive one of the transmission rollers to rotate. It is connected to the outer surfaces of the two transmission rollers through the conveyor belt 5, so that when one of the transmission rollers rotates, the conveyor belt 5 can be driven to rotate through the other transmission roller to form the transportation of tobacco shreds. The guide plate 7 is set up to guide the separated and dispersed tobacco shreds to the inside of the housing 1 for air separation.

[0067] The top of the conveying frame 4 is provided with a separating member 8 for separating the shredded tobacco balls and one or two dispersing members 9 for dispersing the separated tobacco on the conveying belt 5.

[0068] By setting the separator 8, the clumped tobacco formed by shredding can be separated and processed, so that the separated tobacco falls on the conveyor belt 5 in a dispersed state and is transported by the conveyor belt 5. By setting the disperser 9, the tobacco transported on the conveyor belt 5 can be dispersed, so as to avoid the tobacco separated by the separator 8 being too concentrated in the middle part of the conveyor belt 5, so that the color after dispersion will be entangled again later, affecting the subsequent air separation effect.

[0069] Embodiment 2: Based on embodiment 1, the difference is that;

[0070] Refer to the attached Figures 7 to 9 The separator 8 includes a separator 81 fixed to the top of the conveying frame 4 through a support frame, the top and bottom of the separator 81 are both provided with openings, two rotating rollers 82 rotate inside the separator 81, and a plurality of cross-shaped needle bars are fixedly connected to the outer surfaces of the two rotating rollers 82;

[0071] Through the rotation of the two rotating rollers 82, the balled shredded tobacco entering the separation frame 81 can be separated in an orderly manner through a plurality of needle bars on the outer surface.

[0072] A reduction box 83 is fixedly connected to the front of the separation frame 81, and the output end of the reduction box 83 is fixedly connected to one of the rotating rollers 82, and the input end of the reduction box 83 is transmission-connected to one of the transmission rollers through a first belt set 84;

[0073] The reduction box 83 is used to transmit the rotational driving force of the transmission roller to one of the rotating rollers 82, and the rotation speed after transmission can be adjusted, so that the two rotating rollers 82 can rotate at different speeds;

[0074] One ends of the two rotating rollers 82 are connected by a second belt set 85;

[0075] The two rotating rollers 82 are connected through the second belt group 85, so that when one of the rotating rollers 82 rotates, the other rotating roller 82 can be driven to rotate synchronously and in the same direction. Through the synchronous and same-direction rotation of the two rotating rollers 82, the clumping tobacco entering the separation frame 81 can be peeled off and dispersed, and the peeled and dispersed tobacco falls on the top of the conveyor belt 5 in an orderly manner and is transported in an orderly manner through the conveyor belt 5.

[0076] Embodiment 3: Based on embodiment 1, the difference is that;

[0077] Refer to the attached Figure 7 , Figure 8 and Fig.10 The dispersing member 9 includes a U-shaped frame 91 fixed to the top of the conveying frame 4, a sliding frame 92 is slidably connected inside the U-shaped frame 91, a rake frame 93 is fixedly connected to the bottom of the sliding frame 92, and a driving member for moving the sliding frame 92 back and forth is provided on the conveying frame 4;

[0078] By driving the sliding frame 92 forward and backward by the driving member, the rake frame 93 can be driven to move forward and backward. By the forward and backward movement of the rake frame 93, the tobacco concentrated in the middle part of the conveyor belt 5 can be dispersed on both sides, thereby improving the effect of subsequent air separation. By the forward and backward movement of the rake frame 93, combined with the rotation of the conveyor belt 5, the tobacco collected in the middle part can be fully dispersed, solving the problem that the existing separation device cannot completely separate the clumping tobacco, so that the tobacco stem separation effect is affected during the subsequent air separation.

[0079] The driving member includes but is not limited to an electric telescopic rod for driving the sliding frame 92 forward and backward;

[0080] The driving member includes a bidirectional lead screw 94 rotatably connected to one side of the conveying frame 4, the outer surface of the bidirectional lead screw 94 is transmission-connected with a transmission block 95, the transmission block 95 is fixedly connected to the sliding frame 92 through an L-shaped connecting rod 96, and one end of the bidirectional lead screw 94 is transmission-connected to one of the transmission rollers through a third belt set 97;

[0081] The bidirectional screw 94 is connected to one of the transmission rollers through a third belt group 97, so that the rotational driving force of the transmission roller can be transmitted to the bidirectional screw 94, so that the bidirectional screw 94 can rotate synchronously. The rotation of the bidirectional screw 94 can drive the transmission block 95 to reciprocate along the axial direction of the bidirectional screw 94, and then the sliding frame 92 can be driven to reciprocate through the L-shaped connecting rod 96, and finally the rake frame 93 can be driven to reciprocate, thereby forming a dispersion work of the tobacco above the conveyor belt 5. It has a good linkage function, effectively utilizes the driving force of the tobacco conveying, realizes orderly dispersion work, and does not need to set up an additional electric drive source for driving, further improving the function and practicality of the dispersion component 9.

[0082] It should be noted that the term "comprises" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article, or device that includes a series of elements includes not only those elements, but also includes other elements that are not explicitly listed, or also includes elements inherent to such process, method, article, or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article, or device that includes the element.

[0083] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
