[0001] The present invention relates to the field of cigarette formula sample preparation, and particularly to a material distribution device and a sample preparation device for digital formula sample preparation of cigarette leaf groups. Background Art

[0002] In cigarette production, due to the change of tobacco leaf raw materials, it is necessary to adjust the cut tobacco formula in cigarettes and mix cut tobacco of different qualities or different processing methods to maintain the quality and style of cigarettes. With the increasing requirements for cigarette processing and product characteristics, it is necessary to continuously develop new cigarette products according to the changing needs of consumers' tastes. All these tasks require first mixing a small amount of cut tobacco in the laboratory to complete subsequent research work. In order to improve the level of fine processing or conduct research on new product formulas, it is often necessary to mix cut tobacco of different grades in proportion.

[0003] The existing research work on cut tobacco blending often adopts manual operation. The cut tobacco materials are manually sent into the blanking channel, and then the materials are mixed by mixing devices and equipment. The blending method of manual batching not only has low work efficiency, but also has the problem of poor accuracy in controlling the cut tobacco ratio due to human factors. Summary of the Invention

[0020] In some embodiments, a fixing piece is fixedly connected to the discharge pipe, and the fixing piece is fixedly connected to the housing.

[0021] In some embodiments, there are several groups of the material distribution mechanisms, and the types of materials accommodated in each group of the material distribution mechanisms are different. Each group of the material distribution mechanisms has a working position and an idle position, and at any moment, at most one group of the material distribution mechanisms is in the working position. The weighing mechanism is used to receive the materials discharged from the material distribution mechanism in the working position;

[0022] The ingredient dispensing device further includes a switching mechanism, and the switching mechanism is used to drive the material distribution mechanism to switch between the working position and the idle position.

[0023] In some embodiments, there is one group of the driving mechanisms, and the driving mechanism includes:

Detailed description of the specific implementation mode

[0046] The following provides a detailed description of the specific implementation mode of the present invention. It should be understood that the specific implementation mode described herein is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0047] In the present invention, a batching distribution device 1 for cigarette leaf group digital formula sample preparation is provided, which is used to efficiently and accurately obtain the required amount of cut tobacco materials for mixing and sample preparation. As shown in the attached Figure 1As shown, the ingredient dispensing device 1 includes a material distribution mechanism 11, a driving mechanism 12, and a weighing mechanism 4. The material distribution mechanism 11 is used for stable discharging. The driving mechanism 12 provides the discharging power for the material distribution mechanism 11. The weighing mechanism 4 is used for real-time measuring the discharging weight and controlling the driving mechanism 12 to stop running based on the weighing result.

[0048] For the material distribution mechanism 11, it includes a housing 101, a spiral pusher 103, a transmission member 102, and a discharge pipe 104. An accommodation space 105 for accommodating materials is formed in the housing 101. The spiral pusher 103 is rotatably arranged at the bottom of the accommodation space 105. One end of the transmission member 102 is used for receiving the rotational power provided by the driving mechanism 12, and the other end is fixedly connected to the spiral pusher 103. The discharge pipe 104 is fixedly connected to the housing 101 and communicates with the accommodation space 105. The end of the spiral pusher 103 away from the transmission member 102 extends into the discharge pipe 104. By rotating the spiral pusher 103, the materials in the spiral pusher 103 are sent into the discharge pipe 104. Since the spiral pusher 103 is arranged at the bottom of the accommodation space 105, the materials on the upper layer will fall onto the spiral pusher 103 under the action of gravity, enabling the spiral pusher 103 to continuously and stably feed the materials. The weighing mechanism 4 is used for receiving the materials discharged from the discharge pipe 104 and performing real-time weighing measurement on the discharged materials. The weighing mechanism 4 is electrically feedback-connected to the driving mechanism 12, and the driving mechanism 12 is controlled to stop by the weighing measurement result of the weighing mechanism 4. Thus, after weighing the required weight of materials, the driving mechanism 12 is stopped and the material distribution mechanism 11 is controlled to stop feeding, improving the degree of automation.

[0049] The start of the driving mechanism 12 can be manually controlled. Manually controlling the start and operation of the driving mechanism 12 does not affect the accuracy of ingredient dispensing. In actual application, a control system can also be set up. When the driving mechanism 12 needs to be started, it can be controlled to start and run through the control system, further improving the degree of automation.

[0050] Specifically combined with the attached Figure 2As shown, in this embodiment, the accommodating space 105 is arranged with an upward opening, which facilitates adding materials into the accommodating space 105 when the tobacco material in the accommodating space 105 is insufficient. The spiral pusher 103 is rotatably arranged in the bottom of the conical accommodating space 105 in the left-right direction. The transmission member 102 is rotatably installed at the left end of the housing 101, and the left end of the transmission member 102 extends outside the housing 101 for convenient connection with the driving mechanism 12. The right end of the transmission member 102 extends to the bottom of the accommodating space 105 and is fixedly connected to the spiral pusher 103. The discharge pipe 104 is fixedly connected to the right end of the housing 101 and communicates with the accommodating space 105. The right end of the spiral pusher 103 extends into the discharge pipe 104. It should be noted that in actual application, the right end of the spiral pusher 103 should be as flush as possible with the right opening of the discharge pipe 104 on the premise of not exceeding the right opening of the discharge pipe 104, so as to enable the material to be stably conveyed in the discharge pipe 104.

[0051] In addition, the housing 101 and the accommodating space 105 inside it as a whole are in a conical shape with a wider top and a narrower bottom, avoiding the formation of parts at the bottom of the accommodating space 105 where materials can accumulate, so that the materials at this part cannot enter the spiral pusher 103 for conveying.

[0052] In some preferred embodiments, as shown in the attached Figure 2 The batching distribution device 1 further includes a material scattering mechanism 13 and a transmission mechanism 14. The material scattering mechanism 13 includes a stirring component 106 and / or a cutting component 107. The stirring component 106 is used for stirring the materials in the accommodating space 105, and the cutting component 107 is used for cutting the materials at the discharge port of the discharge pipe 104. Since the tobacco materials are prone to accumulate and form lumps, the lumped materials are not only likely to get stuck in the spiral pusher 103 or the discharge pipe 104, but also the lumped materials are likely to affect the batching accuracy. The transmission mechanism 14 is connected between the transmission member 102 and the material scattering mechanism 13 for transmitting the power of the transmission member 102 to the material scattering mechanism 13.

[0053] For example: When the lumped materials have not fallen onto the weighing mechanism 4, the weight of the materials on the weighing mechanism 4 is slightly less than the required material weight. At this time, the lumped materials are sent out from the discharge pipe 104 and fall onto the weighing mechanism 4. At this time, the weight of the materials on the weighing mechanism 4 increases significantly and is much greater than the required material weight, seriously affecting the batching accuracy.

[0054] The setting of the stirring component 106 can stir and break up the lumped materials in the accommodating space 105, not only avoiding blockage in the spiral pusher 103 or the discharge pipe 104, but also improving the batching accuracy. The setting of the cutting component 107 cuts the materials at the discharge port of the discharge pipe 104, cutting the lumped materials into small pieces, avoiding the whole lumped materials from falling onto the weighing mechanism 4, and also being able to improve the batching accuracy.

[0055] When only the stirring assembly 106 is provided in the bulk material mechanism 13, the transmission mechanism 14 transmits the power of the transmission member 102 to the stirring assembly 106. When only the cutting assembly 107 is provided in the bulk material mechanism 13, the transmission mechanism 14 transmits the power of the transmission member 102 to the cutting assembly 107. Preferably, the bulk material mechanism 13 includes a stirring assembly 106 and a cutting assembly 107, and the transmission mechanism 14 transmits the power of the transmission member 102 to the stirring assembly 106 and the cutting assembly 107. The caked materials are broken up by the stirring assembly 106 and the cutting assembly 107 respectively in the accommodation space 105 and at the discharge port of the discharge pipe 104 to ensure the batching accuracy.

[0056] In some preferred embodiments, in combination with the attached Figure 2 As shown, the transmission mechanism 14 includes a driving gear 108, a driven gear 109 and a transmission shaft 110. The driving gear 108 is fixedly connected to the transmission member 102, the driven gear 109 meshes with the driving gear 108, the transmission shaft 110 is rotatably installed in the housing 101, one end of the transmission shaft 110 is fixed to the driven gear 109, and the other end is connected to the bulk material mechanism 13. The gear structure is used for power transmission, with a simple and compact structure and a stable transmission ratio.

[0057] In some preferred embodiments, in combination with the attached Figure 2 and the attached Figure 3 , the stirring assembly 106 includes a stirring member 111, the stirring member 111 is fixedly connected to the transmission shaft 110, and at least part of the stirring member 111 is located in the accommodation space 105, so that the stirring member 111 can contact and stir the materials in the accommodation space 105 during the rotation following the transmission shaft 110. In this embodiment, the position where the transmission shaft 110 is connected to the housing 101 is located outside the accommodation space 105, and a stirring groove 112 is formed in the housing 101 for accommodating the stirring member 111 so that the stirring member 111 can contact the materials in the accommodation space 105. Setting the transmission shaft 110 outside the accommodation space 105 avoids the transmission shaft 110 from contacting the materials. In addition, three stirring members 111 are fixedly connected to the transmission shaft 110, and correspondingly, three stirring grooves 112 are provided. The materials in the accommodation space 105 are fully and comprehensively stirred by the three stirring members 111.

[0058] In some preferred embodiments, in combination with the attached Figure 2 and the attached Figure 3, the cutting assembly 107 includes a cutting member 113 which is fixedly connected to the transmission shaft 110. In this embodiment, the cutting member 113 is cross-shaped. As the cutting member 113 makes one revolution following the transmission shaft 110, the material at the outlet of the discharge pipe 104 is cut four times. An appropriate cutting frequency can, on the one hand, avoid the vibration of the discharge pipe 104 caused by frequent cutting, and on the other hand, reduce the lumped material falling into the weighing mechanism 4 and affecting the batching accuracy.

[0059] In some preferred embodiments, in combination with the attached Figure 4 and the attached Figure 5 , a fixing piece 114 is fixedly connected to the discharge pipe 104, and the fixing piece 114 is fixedly connected to the housing 101. The strength and stability of the discharge pipe 104 are improved by the support of the fixing piece 114. Generally, the fixing piece 114 can be fixed to the discharge pipe 104 by welding or integral molding.

[0060] In some preferred embodiments, there are several groups of the material distribution mechanism 11, and the types of materials contained in each group of the material distribution mechanism 11 are different. Each group of the material distribution mechanism 11 has a working position and an idle position. At any moment, at most one group of the material distribution mechanism 11 is in the working position, and the weighing mechanism 4 is used to receive the material discharged from the material distribution mechanism 11 in the working position. The batching distribution device 1 further includes a switching mechanism 15 which is used to drive the material distribution mechanism 11 to switch between the working position and the idle position.

[0061] As shown in the attached Figure 6 , in this embodiment, the switching mechanism 15 adopts an annular electric guide rail. All the material distribution mechanisms 11 are installed along the annular distribution of the electric guide rail, and the material distribution mechanism 11 is driven to move along the ring by the electric guide rail. The weighing mechanism 4 is arranged on the right side of the annular electric guide rail, and the material distribution mechanism 11 facing the weighing mechanism 4 is in the working position, and the other material distribution mechanisms 11 are in the idle position. The types of materials contained in each group of the material distribution mechanism 11 are different. The material distribution mechanism 11 containing the required material is switched to the working position by the drive of the electric guide rail, and then the required material is quantitatively discharged into the weighing mechanism 4 by the material distribution mechanism 11 in the working position.

[0062] In combination with the attached Figure 2 , to facilitate the installation of the material distribution mechanism 11 on the switching mechanism 15, a support plate 126 is fixedly installed at the bottom of the housing 101 of the material distribution mechanism 11, and a connecting block 127 is installed at the bottom of the support plate 126 and connected to the switching mechanism 15 through the connecting block 127. The support plate 126 provides a platform for the installation of the housing 101 and improves the stability of the material distribution mechanism 11.

[0063] In some preferred embodiments, there is one group of the drive mechanism 12, and the drive mechanism 12 includes a drive motor 116, a drive member 117 and a moving component 118. In combination with the attached Figure 4, appendix Figure 5 and appendix Figure 6 , the driving mechanism 12 is arranged on the inner side of the ring of the electric guide rail, the transmission parts 102 in all the material distribution mechanisms 11 face the inner side of the ring of the electric guide rail, and the discharge pipes 104 face the outer side of the electric guide rail. The driving mechanism 12 is used to provide driving force, the driving part 117 is connected to the power output end of the driving motor 116, and the moving assembly 118 is used to drive the driving motor 116 to move and drive the driving part 117 to be disengaged from and engaged with the transmission part 102 in the material distribution mechanism 11 at the working position. Specifically, the moving part 123 includes a driving cylinder 119 and a piston rod 120, the piston rod 120 is installed on the driving cylinder 119, and the driving motor 116 is fixedly connected to the piston rod 120.

[0064] The driving cylinder 119 is used to drive the piston rod 120 to extend and retract and drive the driving motor 116 to move, so as to drive the driving part 117 to be disengaged from and engaged with the transmission part 102 in the material distribution mechanism 11 at the working position. When the driving part 117 is connected to the transmission part 102 in the material distribution mechanism 11 at the working position, the driving motor 116 is started and drives the transmission part 102 to rotate through the driving part 117, so as to provide rotational driving force for the transmission part 102.

[0065] To improve the stability of the driving motor 116 during movement, as shown in appendix Figure 4 and appendix Figure 5 , a moving part 123 is fixedly connected to the bottom of the driving motor 116, the moving part 123 is fixedly connected to the piston rod 120, and the moving part 123 and the driving cylinder 119 are connected in a guiding and matching manner through a guiding strip 124 and a guiding groove 125. In this embodiment, a guiding groove 125 is opened at the bottom of the moving part 123, a guiding strip 124 matching with the guiding groove 125 extends from the top of the driving cylinder 119, and the length directions of the guiding strip 124 and the guiding groove 125 are the same as the extending and retracting direction of the piston rod 120.

[0066] In addition, one end of the driving part 117 away from the driving motor 116 has a connecting part 121 in a frustum shape, and a frustum-shaped connecting groove 122 is opened at one end of the transmission part 102 away from the spiral pusher 103, and the connecting groove 122 can be frictionally and cooperatively connected with the connecting part 121. The frustum-shaped connecting part 121 and the connecting groove 122 can be connected at any circumferential angle, and it is not necessary to finely adjust the circumferential angle of the connecting part 121 before connecting the connecting part 121 and the connecting groove 122.

[0067] Of course, in other embodiments, teeth can also be provided on the outer periphery of the connecting portion 121 and the inner side of the connecting groove 122 to improve the transmission reliability of the connecting portion 121 and the connecting groove 122 in the connected state. And in the way of connecting through tooth engagement, in order to avoid tooth collision when the connecting portion 121 and the connecting groove 122 are connected, it is necessary to finely adjust the circumferential angle of the connecting portion 121 before connection so that the tooth shape on the connecting portion 121 can mesh with the tooth shape on the inner side of the connecting groove 122.

[0068] In some other preferred embodiments, a plurality of sets of driving mechanisms 12 are provided and are connected to the material distributing mechanism 11 in one-to-one correspondence. The driving mechanism 12 includes a driving motor 116 and a driving member 117. The driving motor 116 is used to provide driving force. The driving member 117 is connected to the power output end of the driving motor 116, and the driving member 117 is fixedly connected to the transmission member 102 in the corresponding material distributing mechanism 11. In this embodiment, the driving of each material distributing mechanism 11 is independent, and there is no need to perform power on / off and clutch operations, so the power input of the material distributing mechanism 11 is more stable.

[0069] In the present invention, a cigarette leaf group digital formula sample preparation device is also provided, including the ingredient distribution device 1 described in any of the above embodiments for precisely mixing ingredients. Combining with the attached Figure 7 , the sample preparation device further includes a loading platform 2, a support platform 3, a storage tank 128, and a robotic arm 5. The loading platform 2 provides a platform for installation. The support platform 3, the weighing mechanism 4, and the robotic arm 5 are all installed on the loading platform 2. The material distributing mechanism 11 and the driving mechanism 12 in the ingredient distribution device 1 are installed on the support platform 3. The support platform 3 is used to lift the material distributing mechanism 11 and the driving mechanism 12 so that the discharge pipe 104 in the material distributing mechanism 11 is located above the weighing mechanism 4.

[0070] A storage tank 128 is provided on the weighing mechanism 4 to receive the materials discharged from the material distributing mechanism 11. On the one hand, it avoids the scattering of the materials, and on the other hand, it is also convenient for the subsequent mixing of the materials. The robotic arm 5 can place the empty storage tank 128 on the weighing mechanism 4, and can also take the storage tank 128 loaded with the mixed materials from the weighing mechanism 4 and stir and mix the materials in the storage tank 128.

Specifically, a tank storage rack 130 is fixedly provided on the loading platform 2. The tank storage rack 130 has a plurality of storage spaces 131 for storing the storage tanks 128. Each storage space 131 can store one storage tank 128. The empty storage tanks 128 and the storage tanks 128 loaded with the mixed materials are all stored on the tank storage rack 130.

[0072] Four first limit members 132 are vertically and fixedly arranged on the loading platform 2. The four first limit members 132 are annularly distributed and enclose a space for limiting the storage tank 128. After the manipulator 5 removes the storage tank 128 loaded with the mixed material from the weighing mechanism 4, it places the storage tank 128 between the four first limit members 132, and then stirs the mixed material in the storage tank 128 through the manipulator 5. The four first limit members 132 prevent the storage tank 128 from shaking. After the stirring is completed, the manipulator 5 moves the storage tank 128 to the tank storage rack 130 for storage.

[0073] Four second limit members 133 are also vertically and fixedly arranged on the loading platform 2. The four second limit members 133 are annularly distributed and enclose a space for storing the lids 129. The lids 129 are stacked in the vertical direction. The manipulator 5 clamps the lid 129 and covers the lid 129 on the storage tank 128 loaded with the mixed material in the tank storage rack 130 to store the mixed material in a sealed manner.
