Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of tobacco production, and particularly relates to a cut tobacco taking production device. BACKGROUND

[0002] Leaf redrying is a common cut tobacco processing technology in the tobacco industry, which forms raw material cut tobacco meeting the production requirements of cigarette enterprises by leaf beating and drying of primary cured tobacco leaves. Redried cut tobacco is generally packaged in corrugated paper boxes, and two standard sizes of 1136mmx720mmx725mm and 1115mmx690mmx725mm are specified in the national standard. After being packed in the paper boxes, the redried cut tobacco is compacted by mechanical extrusion, which greatly reduces the volume of the cut tobacco and facilitates the transportation and storage of the cut tobacco. The weight of the cut tobacco is generally 200kg / box (400kg / box occasionally), and the cut tobacco needs to be cut and loosened before being used for further processing. This processing mode has the following disadvantages: first, the cut tobacco of 200kg is packed in a space of less than 0.5 cubic meters, and it is difficult to ensure the uniformity of the packing density of the cut tobacco; second, the cut tobacco needs to be pre-loosened by cutting before being used for production, which increases the tobacco crushing. These situations are accompanied by the following problems: first, the effect of cut tobacco storage is affected, and unstable packing density can easily cause some tobacco to be pressed and deteriorated; second, the stability of cigarette processing is easily affected during production and processing; third, the high weight makes it extremely difficult to inspect the cut tobacco, and it is difficult to accurately grasp the quality of the cut tobacco.

[0003] To solve the above problems, a divided packaging box is often used when storing tobacco, which divides the packaging box into multiple areas, and the quality of tobacco in each area is the same. The tobacco cutting or inserting process can be omitted during the production of cut tobacco, which reduces the tobacco crushing. However, due to the limitation of the partition, it is not easy to take out the cut tobacco during the production of cut tobacco, and the cut tobacco cannot be connected with the existing cut tobacco production line during the taking process. SUMMARY

[0004] Based on the problems mentioned in the background technology, the present application provides a cut tobacco taking production device to solve the problem that the filling cylinder is difficult to match the use of different divided packaging boxes.

[0007] On the basis of the above technical solution, the application also makes the following improvements:

[0008] Further, the guide flow channel includes a load-bearing plate and a limiting plate, the load-bearing plate is L-shaped, and the corner is a round corner structure.

[0009] Further, the load-bearing plate is inclined downward near one end of the cut tobacco conveying line.

[0010] Further, the load-bearing plate is provided with a mounting groove, and a second push plate is hingedly installed in the mounting groove.

[0011] Further, the guide flow channel is provided with a second reserved slot.

[0012] Further, the length of the second reserved slot is greater than the width of the sealing plate and less than the width of the load-bearing plate.

[0013] Further, the push head group includes a base plate and two push plate groups, each push plate group includes two first push heads and two second push heads, the first push heads are respectively connected to the base plate by first connecting frames, and the second push heads are connected to the base plate by a second connecting frame, the two second push heads are located between the two first push heads, the gaps between the first push heads and the second push heads are located at three equal parts of the transverse direction of the box body, and the gap between the second push heads is located at the middle of the transverse direction of the box body.

[0014] The application also discloses a feeding production method based on the above-mentioned feeding production device.

[0015] Supply calculation: according to the process flow of the cut tobacco pretreatment section of the cut tobacco production line, the feeding cycle is calculated, and the running frequency of the push cylinder and the motor linear rail is set according to the feeding frequency;

[0016] Turnover box: place the packaging box on the feeding mechanism, the pushing cylinder pushes the packaging box, the packaging box slides along the guide flow channel, and the opening end of the packaging box faces one end of the cut tobacco conveying line, while the sealing plate is removed;

[0017] Material taking: use the push head group to push the cut tobacco in the box out, and the pushing cylinder and the motor linear rail return;

[0018] Material replacement: after the material taking is completed, the empty box is taken out, a new packaging box is placed, the pushing cylinder and the motor linear rail work according to the pre-period, and the process is repeated until the extension of the batch is completed.

[0019] The beneficial effects of the present application are:

[0020] 1. Since the first push plate is located at the bottom of the packaging box away from the guide flow channel, when the first push plate pushes the packaging box upwards, the center of gravity of the packaging box is close to the bearing plate, so that the packaging box can slide along the bearing plate and finally be poured on the top of the bearing plate. The cut tobacco in the box can be pushed out by the push head group, which is convenient for production, cancels the cut tobacco cutting or insertion process in cigarette production, and makes the weight of cut tobacco in each grid completely equal, so that the tobacco piece flow in the tobacco production is more accurate and stable, and the control is convenient.

[0021] 2. The special design of the push head group can be applied to two, four and six packaging boxes without adjusting the push head, which is convenient to use.

[0022] 3. The design of the spring and the second push plate can make the box body tilt and fall along the bearing plate on the first push plate under the action of the spring after the cut tobacco in the box is pushed out. The empty packaging box is brought back to the feeding mechanism by the pushing cylinder for replacement, without the need to separately set a taking mechanism on the top of the empty box, thereby reducing the occupation of the workshop space.

Detailed Implementation

[0034] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0035] Example

[0036] like Figures 1-8 As shown, a tobacco sheet feeding production device includes a tobacco shred conveyor line 1 and a packaging box 7. The packaging box 7 includes a box body 71 and a sealing plate 72 that is slidably engaged within the box body 71. An mounting frame 2 and a feeding mechanism 5 are installed on one side of the tobacco shred conveyor line 1. The packaging box 7 is placed on the feeding mechanism 5, and a guide channel 4 is installed on the feeding mechanism 5. The feeding mechanism 5 includes a base frame 51 and a pushing cylinder 52. A first push plate 53 is installed on the shaft of the pushing cylinder. The first push plate 53 is located at the bottom of the packaging box 7 away from the guide channel 4. A motor linear rail 3 is installed on the mounting frame 2. The motor linear rail 3 includes a slide rail 31. A lead screw 32 and a stepper motor 33 that is driven and connected to the lead screw 32 are installed on the slide rail 31. A slide table 34 is slidably installed on the slide rail 31 and screwed onto the lead screw 32. A pusher assembly 6 is fixedly installed on the slide table 34.

[0037] The guiding flow channel 4 comprises a bearing plate 41 and a limiting plate 42, the bearing plate 41 is in the shape of L and the corner is in the structure of a round corner, the design of the round corner structure enables the box 71 to slide along the bearing plate 41 better, thereby avoiding damage of the box 71, the outlet end of the guiding flow channel 4 is provided with a baffle 48, the bearing plate 41 is inclined downward near one end of the tobacco conveying line 1, the box 71 can be in an inclined state, the tobacco in the box 71 is more easily pushed out when the material is pushed, thereby avoiding residual tobacco in the box.

[0038] The bearing plate 41 is provided with a mounting groove, a second push plate 44 is hingedly mounted in the mounting groove, the bearing plate 41 is fixedly connected with a spring mounting bracket 45 and is provided with a first reserved groove 46 at the position of the spring mounting bracket 45, a spring 47 is mounted in the spring mounting bracket 45, one end of the spring 47 is fixed on the spring mounting bracket 45, and the other end is fixed on the second push plate 44 through the first reserved groove 46, after the tobacco in the box 71 is pushed out, the overall mass of the packaging box 7 is reduced, and the box 71 can be inclined and dropped along the bearing plate 41 to the first push plate 53 under the action of the spring 47, and then the empty packaging box 7 is taken back to the feeding mechanism 5 by the pushing cylinder 52 for replacement, so that a material taking mechanism is not needed to be separately arranged on the top of the empty box 71, and the occupancy of the workshop space is reduced.

[0039] The second reserved groove 43 is arranged on the guiding flow channel 4, the sealing plate 72 at the bottom of the box 71 can be taken out from the second reserved groove 43, and since the length of the second reserved groove 43 is greater than the width of the sealing plate 72 and is less than the width of the bearing plate 41, the sealing plate 72 can be disassembled without affecting the disassembly, and the empty box 71 can not be clamped into the second reserved groove 43 when sliding.

[0040] The pushing head group 6 comprises a base plate 61 and two push plate groups, each push plate group comprises two first push heads 62 and two second push heads 63, the first push heads 62 are respectively connected with first connecting frames 641 between the base plate 61, the second push heads 63 are commonly connected with a second connecting frame 642 between the base plate 61, the two second push heads 63 are located between the two first push heads 62, the gaps between the first push heads 62 and the second push heads 63 are respectively located at three equal parts in the transverse direction of the box 71, and the gap between the second push heads 63 is located at the middle part in the transverse direction of the box 71, so that the packaging box of two, four or six grids can be used without adjusting the push head, and the use is convenient.

[0041] It should be noted that the pushing cylinder 52 and the motor linear rail 3 in the present application are both externally connected with a PLC control system.

[0042] When the material is taken, the feeding period T is calculated according to the process flow of the tobacco sheet in the preprocessing section of the tobacco processing line, the running frequency of the pushing cylinder 52 and the motor linear rail 3 is set according to the feeding frequency, the pushing cylinder 52 and the motor linear rail 3 need to work once in one period T, and the packaging box 7 also needs to be replaced once at the same time.

[0043] The packaging box 7 is placed on the base frame 51 and is attached to the load-bearing plate 41. The pusher cylinder 52 is started, and the first push head 62 drives the packaging box 7 to rise. When the packaging box 7 rises to the corner of the load-bearing plate 41, the packaging box 7 tilts on the top end of the load-bearing plate 41 and slides along the load-bearing plate 41 due to the change of the center of gravity. The packaging box 7 is stopped under the restriction of the baffle 48. At this time, the open end of the packaging box 7 is located at the upper end of the cut tobacco conveying line 1. The second push plate 44 is lowered under the weight of the tobacco leaves and does not interfere with the sliding of the packaging box 7. Then, the sealing plate 72 is taken out from the second reserved slot 43. The linear motor rail 3 is started to drive the push head group 6 to move and push the tobacco leaves in the box 71 out. Then, the linear motor rail 3 is controlled to return to the original position to drive the push head group 6 to separate from the box 71. At this time, the mass of the box 71 is reduced. The spring 47 returns to the original position to drive the second push plate 44 to rotate and make the box 71 tilt to change the center of gravity of the box 71. After the center of gravity of the box 71 is changed, the box 71 slides along the load-bearing plate 41 to the first push head 62. Then, the pusher cylinder 52 is controlled to return to the original position. Finally, the empty box 71 is taken off, and a new packaging box 7 is put on. After the cycle T ends, the operation is performed again.

[0044] During the pushing process, when the box 71 has two compartments, the two compartment interval corresponding regions each correspond to a push plate group. When the packaging box 7 has four compartments, the four compartment interval corresponding regions each correspond to a first push head 62 and a second push head 63. The four compartment interval corresponding regions on both sides each correspond to a first push head 62. The two compartment interval corresponding regions in the middle each correspond to two second push heads 63 in the same push plate group.

[0045] The above provides a detailed introduction to the tobacco sheet taking and producing device. The specific embodiment is only used to help understand the method and the core idea of the present application. It should be pointed out that, for those skilled in the art, without departing from the principle of the present application, the present application can be improved and modified in several ways. These improvements and modifications also fall within the protection scope of the present application.
