[0002] The production of all brands of tobacco in the silk thread production line has a strictly confidential leaf group formula. The tobacco raw materials in the formula come from different origins and different brands and specifications, and are subsequently processed according to certain formula requirements. During production, the pre-dispensing cabinet material laying car has been running in advance, and the position of each batch of tobacco leaves falling on the laying car is random, which causes the random laying of tobacco leaves in the pre-dispensing cabinet, and cannot ensure that the tobacco formulas of various brands and specifications are evenly mixed, which has a certain impact on the intrinsic quality of cigarette products.

[0003] Therefore, how to provide a tobacco pre-dispensing cabinet laying vehicle has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0004] The utility model aims to provide a material spreading vehicle for a tobacco pre-distribution cabinet.

[0005] According to the utility model, a material laying vehicle for a tobacco pre-distribution cabinet is provided, comprising a material laying belt, a material laying vehicle, a sensor sheet, a first proximity switch and a second proximity switch;

[0006] The material laying crane is installed on the pre-distribution cabinet and can run on the pre-distribution cabinet; the material laying belt is installed on the material laying crane and can run on the material laying crane; the sensor sheet is fixed on the material laying crane; the first proximity switch is installed above the pre-distribution cabinet 1 in the direction of the tail end of the pre-distribution cabinet; the second proximity switch is installed above the pre-distribution cabinet in the direction of the discharge end of the pre-distribution cabinet.

[0007] Optionally, the paving vehicle further comprises: a paving belt motor reducer and a paving belt frequency converter;

[0008] The paving belt motor reducer is installed on one side of the paving belt;

[0009] The paving belt motor reducer is electrically connected to the paving belt frequency converter;

[0010] The material laying belt frequency converter is electrically connected to the control system.

[0011] Optionally, the paving vehicle further comprises: a paving belt driving shaft and a paving belt driven shaft;

[0012] The material paving belt driving shaft and the material paving belt motor reducer are driven by a chain transmission to drive the material paving belt driven shaft and the material paving belt to run.

[0013] Optionally, the paving vehicle further comprises: a track;

[0014] The tracks are symmetrically distributed on both sides above the pre-distribution cabinet; the material laying vehicle is installed on the pre-distribution cabinet through the tracks and can run on the pre-distribution cabinet.

[0015] Optionally, the paving vehicle further comprises: a paving vehicle motor reducer and a paving vehicle frequency converter;

[0016] The motor reducer of the paving crane is installed on one side of the paving crane;

[0017] The motor reducer of the paving crane is electrically connected to the frequency converter of the paving crane;

[0018] The material paving crane frequency converter is electrically connected to the control system.

[0019] Optionally, the paving vehicle further comprises: a paving vehicle driving roller and a paving vehicle driven roller;

[0020] The active rollers and driven rollers of the paving crane are installed below the paving crane and on the track; the motor reducer of the paving crane drives the active rollers of the paving crane to run through a chain transmission, driving the driven rollers of the paving crane and the paving crane to run on the track.

[0021] According to the utility model, a material laying vehicle for a tobacco pre-distribution cabinet is provided, and its precise material laying control method and working principle are as follows:

[0022] When the production start section is automatically running, the production brand will be issued to the control system along with the work order, and the material spreading crane will run back and forth normally at the calculated frequency value, and the material spreading belt will run back and forth with the material spreading crane at the same frequency value. At this time, the preceding equipment has not yet passed the material, and its operation can be judged whether it is normal by the running status of the material spreading belt; when the tobacco leaves pass through the electronic scale of the preceding equipment, no matter where the current position of the material spreading crane is, it must return to the starting position of the discharge end of the pre-distribution cabinet and wait. After the delay time is reached, the head of each batch of tobacco leaves will fall on the material spreading belt, and the material spreading crane and the material spreading belt will start to run toward the rear end of the pre-distribution cabinet, and the delivered tobacco leaves will be sent from the middle area of ​​the pre-distribution cabinet to the rear end of the pre-distribution cabinet. The material spreading crane moves while the material spreading belt spreads the material. When the sensor plate at the end of the material spreading carriage detects the first proximity switch, it sends a signal to the control system. The control system controls the reversing of the motor reducer of the material spreading carriage and the motor reducer of the material spreading belt to start reverse material spreading. At this time, the material spreading carriage runs from the rear end of the pre-distribution cabinet to the discharge end of the pre-distribution cabinet, and the material spreading belt delivers the delivered tobacco leaves from the middle area of ​​the pre-distribution cabinet to the discharge end of the pre-distribution cabinet into the storage cabinet. When the sensor plate at the end of the material spreading carriage detects the second proximity switch, it sends a signal to the control system. The control system controls the reversing of the motor reducer of the material spreading carriage and the motor reducer of the material spreading belt to start reverse material spreading. At this time, a pack of tobacco leaves that has just been mixed with thin slices is flattened into the pre-distribution cabinet, thus realizing reciprocating strip spreading until the batch production is completed.

[0023] Optionally, the method for calculating the frequency value includes:

[0024] f=(50*80) / T

[0025] T=(3600*W) / SP

[0026] W = 200 [1 + (water value after adding water - water value before adding water) %] + 200 * k

[0027] Among them, 200 is the weight of a bag of tobacco leaves, in kg; W is the weight of a bag of tobacco leaves plus slices, in kg; k is the proportion of slices; T is the running time of tobacco leaves after blending, in s; SP is the set flow rate for one feeding, in kg / h; 50 is the frequency value of the spreading vehicle under working conditions, in Hz; 80 is the time it takes for the spreading vehicle to go back and forth once under working conditions, in s; 3600 is the number of seconds in 1 hour; f is the frequency value, in Hz.

[0028] According to the technical content disclosed in the utility model, the following beneficial effects are achieved: the material laying crane and material laying belt are controlled by variable speed operation of the frequency converter, and the corresponding frequency values ​​are calculated according to different cigarette brands during the production process for automatic control. Because the material laying crane and material laying belt of the pre-distribution cabinet material laying car can only ensure the uniformity of material entering the cabinet if they run at the same speed, the material laying crane and material laying belt can run at the same speed according to the calculated required frequency value; when the tobacco leaves arrive at the material laying car during automatic operation, the current position of the material laying car is uncertain, so the material signal of the previous roller machine is used for judgment. No matter where the current position of the material laying car is, after the material signal of the roller is given, the material laying car must return to the starting position and wait. After the delay time is reached, the material laying crane starts to run when the head of each batch of tobacco leaves falls on the material laying belt. In this way, it can be ensured that the head of tobacco leaves of any brand falls on the material laying car at the same position, so as to ensure that each pack of tobacco leaves is laid flat in the pre-distribution cabinet.

[0055] According to the utility model, a material laying vehicle for a tobacco pre-distribution cabinet is provided, and its precise material laying control method and working principle are as follows:

[0056] When the production start section is automatically running, the production brand will be issued to the control system along with the work order, and the material spreading crane 17 will run back and forth normally at the calculated frequency value, and the material spreading belt 4 will run back and forth at the same frequency value as the material spreading crane 17. At this time, the preceding equipment has not yet passed the material, and its operation can be judged whether it is normal by the running status of the material spreading belt 4; when the tobacco leaves pass through the electronic scale of the preceding equipment, no matter where the current position of the material spreading crane 17 is, it must return to the starting position of the discharge end 15 of the pre-distribution cabinet and wait. After the delay time is reached, the head of each batch of tobacco leaves will fall on the material spreading belt 4, and the material spreading crane 17 and the material spreading belt 4 will start to run toward the rear end 16 of the pre-distribution cabinet, and the delivered tobacco leaves will be sent from the middle area of ​​the pre-distribution cabinet to the rear end 16 of the pre-distribution cabinet 2, while the material spreading crane 17 is moving and the material spreading belt 4 is spreading the material.

When the material paving crane 17 reaches the end sensor 12 and detects the second proximity switch 14, a signal is sent to the control system. The control system controls the material paving crane motor reducer 6 and the material paving belt motor reducer 3 to reverse direction and start reverse material paving. At this time, a pack of tobacco leaves that has just been mixed with thin slices is flattened into the pre-distribution cabinet, thus realizing reciprocating strip paving until the batch production is completed.

[0057] In some embodiments, the method for calculating the frequency value includes:

[0058] f=(50*80) / T

[0059] T=(3600*W) / SP

[0060] W = 200 [1 + (water value after adding water - water value before adding water) %] + 200 * k

[0061] Among them, 200 is the weight of a bag of tobacco leaves, in kg; W is the weight of a bag of tobacco leaves plus slices, in kg; k is the proportion of slices; T is the running time of tobacco leaves after blending, in s; SP is the set flow rate for one feeding, in kg / h; 50 is the frequency value of the spreading vehicle under working conditions, in Hz; 80 is the time it takes for the spreading vehicle to go back and forth once under working conditions, in s; 3600 is the number of seconds in 1 hour; f is the frequency value, in Hz.

[0062] Specifically, the parameters of different brands are shown in Table 1.

[0063] Table 1

[0064]

[0065] Tobacco leaves need to be watered after the previous loosening and rehumidification process. Since the proportion of thin slices in each package of tobacco leaves is different, the weight of each package of tobacco leaves after the thin slices are mixed is also different. According to the formula W=200[1+(moisture value after water addition-moisture value before water addition)%[+200*k, the total weight of each package of tobacco leaves after water addition plus the thin slices can be calculated; according to the flow value set for each brand of electronic scale, the time required for each package of tobacco leaves after mixing to pass the electronic scale can be calculated according to the formula T=(3600*W) / SP; according to the formula f=(50*80) / T, the frequency value required for the cloth car to reciprocate once for each package of tobacco leaves plus the mixed thin slices to be laid flat in the pre-distribution cabinet can be calculated.

[0066] In summary, the technical content disclosed by the utility model is that the material laying crane and material laying belt adopt variable speed operation control of the frequency converter, and the corresponding frequency value is calculated according to different cigarette brands during the production process for automatic control. Because the material laying crane and material laying belt of the pre-distribution cabinet material laying car must run at the same speed to ensure the uniformity of material entering the cabinet, the material laying crane and material laying belt can run at the same speed according to the calculated required frequency value; when the tobacco leaves arrive at the material laying car during automatic operation, the current position of the material laying car is uncertain, so the material signal of the previous roller machine is used for judgment. No matter where the current position of the material laying car is, after the material signal of the roller is given, the material laying car must return to the starting position and wait. After the delay time is reached, the material laying crane starts to run when the head of each batch of tobacco leaves falls on the material laying belt. In this way, it can be ensured that no matter what brand of tobacco leaves fall on the material laying car, they are in the same position, so as to ensure that each pack of tobacco leaves is laid flat in the pre-distribution cabinet.
