The above is the optimal arrangement of the mounting frame 12. The mounting frame 12 may be otherwise configured. For example, the side bracket 122 is provided in the form of a pure bracket, without the side plates 1224; the first mounting plate 1 is vertical to the tobacco leaf conveying belt machine, the edge of the first mounting plate 1, which is far away from the tobacco leaf conveying belt machine, is connected with the second mounting plate 2, and the first mounting plate 1 and the second mounting plate 2 form an upward slope along the conveying direction of the tobacco leaf conveying belt machine; the adjacent side of the edge of the first mounting plate 1, which is far away from the tobacco leaf belt conveyor, is connected with a first side 1223 of a side bracket which is equal to the upper bottom side of the right trapezoid, and the adjacent side of the edge of the second mounting plate 2, which is connected with the first mounting plate 1, is connected with a top 1222 of the side bracket which is equal to the waist of the oblique side of the right trapezoid; the side support 122 has no bottom edge, only the bottom of the first side edge 1223 of the side support and the bottom of the second side edge of the side support are provided with mounting holes, and the bin dividing device 1 is mounted on the machine frame above the tobacco leaf conveying belt machine through the mounting holes at the bottom of the two side edges.

The corresponding stripper plate of one suction and pick-up mechanism 11 is provided with openings 133, and the number of the openings 133 is matched with the number of the negative pressure suction pipes 1111 of the suction and pick-up mechanism 11. The utility model discloses in, two negative pressure straws 1111 of two preferred openings 133. The transport mechanism of the collecting device 2, i.e. the collecting belt, is located below the stripper plate and the outer edge of the collecting belt is further away from the mounting frame 12 than the outer edge of the stripper plate bend 132.

After the device is operated, the fan 16 provides negative pressure for the negative pressure suction pipe 1111 through the negative pressure pipe 17, after a system instruction is received, the quick cylinder 1123 quickly extends out to enable the suction pipe rack to quickly move downwards so that the negative pressure suction pipe 1111 quickly approaches to the tobacco leaf conveying belt machine, and the distance between the negative pressure suction pipe 1111 and the conveying belt just accommodates the tobacco leaves to smoothly pass through; the tobacco leaves move to the lower part of the negative pressure suction pipe 1111 along with the conveying belt, the negative pressure suction pipe 1111 sucks the tobacco leaves, the quick cylinder 1123 retracts quickly at the moment, the negative pressure suction pipe 1111 is far away from the tobacco leaf conveying belt quickly, then the inclined pulling cylinder 1121 retracts to drive the suction picking part 111 to move upwards in the direction of the mounting rack 12 in an inclined mode; when the two negative pressure suction pipes 1111 enter the openings 133 of the discharging plate, the tobacco leaves sucked by the negative pressure suction pipes 1111 are positioned below the discharging plate, the oblique pulling air cylinder 1121 continuously retracts, the negative pressure suction pipes 1111 continuously incline upwards, the tobacco leaves are blocked by the discharging plate so as to be separated from the negative pressure suction pipes 1111, the tobacco leaves fall onto the collecting belt due to the self gravity, and the collecting belt conveys the tobacco leaves falling onto the collecting belt to the corresponding collecting frame.

The utility model discloses in, fan 16 is the frequency conversion fan, and wind speed, amount of wind, wind pressure are all adjustable. The weight range of each tobacco leaf may be different for different batches or varieties of tobacco leaves, and each parameter of the fan 16 may be adjusted to provide a suitable negative pressure to the suction mechanism 11, so that the suction mechanism 11 can smoothly suck, pick and move the tobacco leaves.

The utility model discloses an among the preferred scheme, inhale and pick up part 111 that picks up mechanism 11 and set up two negative pressure straws 1111, can ensure to pick up the tobacco leaf of part 111 below through inhaling and can be inhaled by negative pressure straw 1111 smoothly. When a piece of tobacco leaves passes below the suction component 111 of the suction mechanism 11, the passing position is not necessarily just under the horizontal mounting plate of the suction pipe support 1112, for example, more than one half of the horizontal mounting plate is outside the position where the tobacco leaves pass, if only one negative pressure suction pipe 1111 is arranged at the center of the horizontal mounting plate, the negative pressure suction pipe 1111 cannot successfully suck the tobacco leaves, but under the condition that two negative pressure suction pipes 1111 are arranged, the two negative pressure suction pipes 1111 are both in the position one fourth long of the horizontal mounting plate, and the negative pressure suction pipe 1111 near the piece of tobacco leaves can smoothly suck and pick up the piece of tobacco leaves. The two suction pipes 1111 are not necessarily located one quarter of the length of the horizontal mounting plate, but may be located one fifth or one sixth of the length of the horizontal mounting plate, but the one quarter is the most preferable since the suction by the other suction mechanism 11 is better when approximately three quarters of the area of a leaf is not located under the horizontal mounting plate. In addition, if a relatively large tobacco leaf passes right below the suction component 111 of the suction mechanism 11, and only one negative pressure suction pipe 1111 is disposed at the center of the horizontal mounting plate, there is a possibility that the suction force provided by the negative pressure suction pipe 1111 cannot firmly suck and pick up the tobacco leaf, and two negative pressure suction pipes 1111 can firmly suck and pick up the tobacco leaf; if the tobacco leaves are small, two negative pressure suction pipes 1111 can respectively suck and pick up one tobacco leaf, and the tobacco leaf sucking and picking efficiency is improved. The angle between the negative pressure suction pipe 1111 and the tobacco leaf conveying belt is 45-90 degrees, and the preferable scheme is that the negative pressure suction pipe 1111 is vertical to the tobacco leaf conveying belt, because when the negative pressure suction pipe 1111 and the tobacco leaf conveying belt are vertical, the adsorption force of the negative pressure suction pipe 1111 to the tobacco leaves is the largest.

The utility model discloses in, it sets up quick cylinder 1123 to inhale moving part 112 that picks up mechanism 11, and quick cylinder 1123 links to each other with negative pressure straw 1111 through straw support 1112, can make negative pressure straw 1111 be close to tobacco leaf belt conveyor fast, inhales and picks up and keeps away from tobacco leaf belt conveyor fast behind the tobacco leaf, saves time, raises the efficiency. Even if the quick cylinder 1123 is not provided, the suction and picking component 111 and the moving component 112 can complete suction, picking and conveying of the tobacco leaves, but only the tobacco leaves can be conveyed slowly by the acting force of the inclined pulling cylinder 1121, which takes a long time and has relatively low efficiency. The inclined pulling cylinder 1121 is disposed on the moving member 112 of the suction and pickup mechanism 11 to change the moving direction of the tobacco leaves sucked and picked up by the suction and pickup member 111, so as to smoothly move the tobacco leaves above the tobacco leaf collecting belt. Compared with a gear train and other commutators, the cable-stayed cylinder 1121 has the advantages of simple structure, small occupied space and relatively low cost.

The utility model discloses in, shedding mechanism 13 is the stripper, and the stripper sets up opening 133, and opening 133's degree of depth is greater than the width of stripper kink 132, cooperates with negative pressure straw 1111, and the whole piece of ability all is in stripper kink 132 below when making the tobacco leaf remove the position that the stripper was located along with oblique pull cylinder 1121, ensures that the tobacco leaf breaks away from negative pressure straw 1111 and falls on the tobacco leaf collection belt smoothly. If the discharging plate is not provided with the notch 133, when the tobacco leaves move to the position where the discharging plate is located, only part of the tobacco leaves are located below the bending part 132 of the discharging plate, and the force applied to the tobacco leaves by the discharging plate may not enable the tobacco leaves to be separated from the negative pressure suction pipe 1111, even if the tobacco leaves are enabled to be separated from the negative pressure suction pipe 1111, the tobacco leaves may float out of the tobacco leaf collecting belt in the falling process due to uneven stress of the tobacco leaves. The depth of the notch 133 is greater than the width of the bending part 132 of the stripper plate, i.e. the notch 133 extends to the horizontal plate 131 and then continues to extend to the direction of the first mounting plate 1211 for a certain distance, so as to avoid the collision between the negative pressure suction pipe 1111 and the horizontal plate 131 in the process of inclining upwards. The suction and pick-up mechanism 11 is matched with the discharge mechanism 13, so that after the tobacco leaves are separated from the negative pressure suction pipe 1111 and fall onto the collection belt, the inclined pulling cylinder 1121 continuously inclines and upwards runs for a certain distance, and when the negative pressure suction pipe 1111 is positioned above the horizontal plate 131 of the discharge plate, the upward movement is stopped. At this time, the negative pressure in the negative pressure suction pipe 1111 has little influence on the tobacco leaves, and the tobacco leaves can smoothly fall onto the collection belt. If the discharging plate is only a horizontal plate 131 without a bending part 132, the tobacco leaves can be separated from the negative pressure suction pipe 1111, but the tobacco leaves are just under the negative pressure suction pipe 1111 after being separated from the negative pressure suction pipe 1111, namely, the tobacco leaves may not smoothly and quickly fall onto the collecting belt in the negative pressure influence range of the negative pressure suction pipe 1111. The discharging mechanism 13 may be provided with other arrangements, such as a valve in the negative pressure suction pipe 1111 or at the connection between the negative pressure suction pipe 1111 and the negative pressure pipe 17, and the negative pressure suction pipe 1111 sucks and picks up and releases the tobacco leaves by controlling the opening and closing of the valve.

The side bracket 122 of the mounting frame 12 is a side bracket 122 including a side plate 1224. the structure includes the side bracket 122 and the side plate 1224 cooperating with the side bracket 122 to make the side bracket 122 more stable. The side support 122 is a pure support structure, and can also support the suction mechanism 11 and the discharging plate to complete the separation of the tobacco leaves, but the stability is not good enough. The first mounting plate 1211 of the mounting frame 12 is a side-turned V-shaped corner plate that provides sufficient space for the suction and pick-up mechanism 11 to operate so that the moving member 112 of the suction and pick-up mechanism 11 does not rub or hit the first mounting plate 1211, reducing wear. If the first mounting plate 1211 of the mounting frame 12 is a straight plate perpendicular to the tobacco conveying belt, the suction and pickup mechanism 11 and the discharge plate can be supported to complete the separation of the tobacco, but the moving member 112 of the suction and pickup mechanism 11 may rub or collide against the first mounting plate 1211 to cause abrasion and affect the service life.

All the suction and pickup mechanisms 11 of the bin dividing device 1 can be arranged on the same straight line, i.e. distributed on the same side of the installation frame 12, but the distribution mode is too dense, and when two adjacent suction and pickup mechanisms 11 operate, friction or collision may occur, which affects the tobacco leaf bin dividing process. In order to make the two adjacent suction and pickup mechanisms 11 have enough space to operate without interfering with each other, the suction and pickup mechanisms 11 may be disposed on both sides of the mounting frame 12, that is, as shown in fig. 1, 2 and 4, the suction and pickup mechanisms 11 are uniformly disposed on both sides of the mounting frame 12 in the conveying direction of the tobacco leaf conveying belt. In the suction and pickup mechanisms 11 on the same side, a distance capable of accommodating one suction and pickup element 111 is left between the suction and pickup elements 111 of two adjacent suction and pickup mechanisms 11, and the position of the other side of the mounting frame 12 symmetrical to the position of the distance is the position of the suction and pickup element 111 of the suction and pickup mechanism 11 arranged on the other side of the mounting frame 12. Accordingly, the position on the other side of the mounting frame 12 opposite to the position vacated between the moving parts 112 of the two adjacent suction and pickup mechanisms 11 is the position where the moving part 112 of the suction and pickup mechanism 11 arranged on the other side of the mounting frame 12 is located. With this arrangement, the tobacco leaves which are not sucked by the suction mechanism 11 on one side of the mounting frame 12 are smoothly sucked by the suction mechanism 11 on the other side of the mounting frame 12, that is, each tobacco leaf can be sucked by the suction mechanism 11 and moved to the tobacco leaf collecting belt.

In the case that the suction and pick-up mechanism 11 is disposed on both sides of the mounting frame 12, in order to make the bin dividing mechanism more stable, the side bracket of the mounting frame 12 is also changed, as shown in fig. 2 and 4, on one side of the mounting frame 12, the second side edge of the side bracket, which is equal to the lower bottom edge of the right trapezoid, extends for a certain distance along the conveying direction of the tobacco leaf conveying belt, and the mounting plate and the side bracket 122 are disposed in the conveying direction of the conveying belt by using the second side edge at the position as a symmetry axis. At this time, a new side frame is formed, and the second side edge of the side frame, which extends for a certain distance along the conveying direction of the tobacco leaf conveying belt, is positioned on the vertical shaft section of the newly-installed frame 12, and the side plates on the side frame are also formed in the above manner. Certainly, the above is only a description mode, and in the new side bracket, because the side plate is arranged and has a symmetrical structure, the second side edge does not need to exist, and the side plate is not formed by splicing two extended original side plates. In the new side stand, the first side 1223 of the original side stand, which is the same as the upper base of the right trapezoid, becomes the new two sides, and the side plate is a plate matching the shape of the new side stand.

A through hole is arranged on the side plate of the bracket on the side of the installation frame 12, the negative pressure pipe 17 penetrates through the installation frame 12 through the through hole, and the axis of the negative pressure pipe 17 is positioned on the vertical shaft section of the installation frame 12, which is a preferable arrangement scheme of the negative pressure pipe 17. The negative pressure pipe 17 may be disposed above the installation frame 12 or at other positions as long as it can communicate with the fan 16 and can supply negative pressure to the negative pressure suction pipe 1111.
