Description

Technical Field

[0001] The utility model relates to the technical field of cigarette experiment equipment, in particular to a belt conveying tobacco shred feeding and weighing system. Background Art

[0002] In the cigarette production process, smokers' satisfaction and comfort need to be considered while ensuring the safety of tobacco products. Studies have shown that the intrinsic qualities of cigarettes, such as the ratio of tobacco product ingredients, tobacco filling density, and filling uniformity, have an impact on the aroma quality and the release of harmful components in the smoke. Therefore, in order to improve the intrinsic quality of cigarettes, laboratory personnel of tobacco companies will change the ratio of tobacco products and develop new formula tobacco products. When developing new formula tobacco products, it is necessary to prepare cigarettes with well-proportioned formula tobacco and conduct smoking aroma tests. However, since it is an experimental test sample, the amount of formula tobacco is small, and it is impossible to prepare formula cigarettes on the cigarette production line.

[0003] Among them, the preparation and testing of formula cigarettes have high requirements for the weight accuracy of tobacco. Currently, most laboratory personnel weigh tobacco manually, which is labor-intensive, has high labor costs, and has extremely low weighing efficiency and poor weighing accuracy, resulting in low filling efficiency and may also contaminate tobacco, affecting test results.

[0004] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the invention

[0005] The purpose of the utility model is to address the deficiencies of the prior art and thus provide a belt conveyor tobacco feeding weighing system. The utility model has high weighing accuracy and high weighing efficiency, improves tobacco filling efficiency, has a high degree of mechanization, has low labor intensity, has low labor costs, avoids tobacco pollution, and ensures test results.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a belt conveyor tobacco feeding and weighing system, including a lifting belt conveyor, a horizontally pulled belt conveyor, a weighing tray and an electronic scale, the lifting belt conveyor is obliquely arranged on one side of the horizontally pulled belt conveyor, the lifting belt conveyor transports from bottom to top to lift the tobacco, the upper end of the lifting belt conveyor is arranged above one end of the horizontally pulled belt conveyor, and the other end of the horizontally pulled belt conveyor is arranged directly above the weighing tray, the weighing tray is placed on the electronic scale, and the horizontally pulled belt conveyor catches the tobacco dropped from the upper end of the lifting belt conveyor and transports the tobacco to the weighing tray.

[0007] Based on the above, the running speed of the horizontal belt conveyor is greater than the running speed of the lifting belt conveyor.

[0008] Based on the above, a plurality of lifting ribs arranged at equal intervals are fixedly connected to the outer surface of the belt of the lifting belt conveyor along its width direction.

[0009] Based on the above, the belt-conveyed tobacco feeding and weighing system also includes a hopper, which is fixedly installed on the upper part of both sides of the frame of the lifting belt conveyor. The upper side, lower side and one side close to the upper end of the lifting belt conveyor of the hopper are open. There is a gap between the lower side edge of a side plate of the hopper close to the lower end of the lifting belt conveyor and the belt of the lifting belt conveyor, and the gap is 1-5mm larger than the height of the lifting rib.

[0010] Based on the above, a material blocking cover is provided on the outside of the lower rotating part of the lifting belt conveyor, and the upper edge of the material blocking cover is fixedly connected to the outer surface of a side plate of the hopper near the lower end of the lifting belt conveyor.

[0011] Based on the above, the electronic balance is a precision balance, which includes a balance body and a balance tray arranged on the balance body. The balance body is arranged below the output end of the horizontally pulled belt conveyor, and the weighing tray is placed on the balance tray.

[0012] Based on the above, the width of the weighing tray is greater than the belt width of the horizontally stretched belt conveyor.

[0013] Based on the above, the weighing pallet includes a C-shaped plate with the open side facing downward, and a downwardly concave pan body is integrally formed in the middle of the upper side plate of the C-shaped plate. The pan body is located directly below the output end of the horizontally pulled belt conveyor. The bottom of the pan body is higher than the lower sides of the two side plates of the C-shaped plate. The lower sides of the two side plates of the C-shaped plate are supported on the balance pallet, and the width of the pan body is greater than the belt width of the horizontally pulled belt conveyor.

[0014] Based on the above, the belt width of the horizontal pull-out belt conveyor is greater than that of the lifting belt conveyor.

[0015] The utility model has substantial characteristics and progress compared with the prior art. Specifically, the utility model lifts the tobacco by the lifting belt conveyor and evenly transports the tobacco in batches to the horizontally pulled belt conveyor. Since the running speed of the horizontally pulled belt conveyor is greater than the running speed of the lifting belt conveyor, the tobacco output from the lifting belt conveyor can be pulled more evenly by the horizontally pulled belt conveyor. The horizontally pulled belt conveyor then uniformly transports the evenly pulled tobacco in batches to the weighing tray. The weighing tray receives the tobacco and weighs it through an electronic balance. The electronic The balance is a precision balance to ensure that the weight error is within the specified range. When the weight of the tobacco weighed by the weighing tray reaches the requirement, the lifting belt conveyor and the horizontal pull-out belt conveyor stop running, the weighing tray is taken away manually, and the tobacco in the weighing tray is poured out and provided to the filling process. Then, the weighing tray is put back in place and the lifting belt conveyor and the horizontal pull-out belt conveyor are started, and the weighing tray continues to receive tobacco. The weighing accuracy is high, the weighing efficiency is high, the filling efficiency is improved, the mechanization degree is high, the labor intensity is low, the labor cost is low, tobacco pollution is avoided, and the test results are guaranteed.

[0016] Among them, a number of lifting ribs arranged at equal intervals are fixedly connected on the outer surface of the belt of the lifting belt conveyor along its width direction. The lifting ribs can separate the tobacco evenly and effectively lift the tobacco. When the tobacco is lifted from bottom to top with the lifting ribs, the tobacco higher than the lifting ribs can slide down under the action of its own weight due to the inclined setting of the lifting belt conveyor. Then, when two adjacent lifting ribs move from bottom to top to the upper end of the lifting belt conveyor, the tobacco between the two adjacent lifting ribs is flush with the upper side edges of the two adjacent lifting ribs, ensuring that the volume of tobacco output by the lifting belt conveyor is the same each time, and the tobacco is more accurately and evenly provided to the horizontally pulled belt conveyor in batches. The horizontally pulled belt conveyor can evenly pull the batches of tobacco apart, ensuring that the tobacco is evenly delivered to the weighing tray.

[0017] The hopper is used to load tobacco, and the blocking cover is used to prevent some tobacco from falling from the lower end of the lifting belt conveyor. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The technical solution of the utility model is further described in detail below through specific implementation methods.

[0024] Example 1

[0025] like Figure 1-4 As shown, the belt conveyor tobacco feeding and weighing system includes a lifting belt conveyor 1, a horizontally pulled belt conveyor 2, a weighing tray 3 and an electronic scale. The lifting belt conveyor 1 is tilted and arranged on one side of the horizontally pulled belt conveyor 2. The lifting belt conveyor 1 transports from bottom to top to lift the tobacco. The upper end of the lifting belt conveyor 1 is arranged above one end of the horizontally pulled belt conveyor 2, and the other end of the horizontally pulled belt conveyor 2 is arranged directly above the weighing tray 3. The weighing tray 3 is placed on the electronic scale, and the horizontally pulled belt conveyor 2 catches the tobacco dropped from the upper end of the lifting belt conveyor 1 and transports the tobacco to the weighing tray 3.

[0026] The running speed of the horizontally stretched belt conveyor 2 is greater than the running speed of the lifting belt conveyor 1, so as to ensure that the horizontally stretched belt conveyor 2 can stretch the tobacco outputted from the lifting belt conveyor 1 more evenly.

[0027] A plurality of lifting ribs 4 arranged at equal intervals are fixedly connected to the outer surface of the belt of the lifting belt conveyor 1 along its width direction.

[0028] The belt conveyor tobacco feeding and weighing system also includes a hopper 5, which is fixedly mounted on the upper parts of both sides of the frame of the lifting belt conveyor 1. The upper side, the lower side and the side close to the upper end of the lifting belt conveyor 1 of the hopper 5 are open. There is a gap between the lower side of a side plate of the hopper 5 close to the lower end of the lifting belt conveyor 1 and the belt of the lifting belt conveyor 1, and the gap is greater than the height of the lifting rib 4 by 1-5mm. The hopper 5 is used to put tobacco.

[0029] The lower end of the lifting belt conveyor 1 is covered with a material blocking cover 6, and the upper edge of the material blocking cover 6 is fixedly connected to the outer side of a side plate of the hopper 5 near the lower end of the lifting belt conveyor 1. The material blocking cover 6 is used to prevent some tobacco from falling from the lower end of the lifting belt conveyor 1.

[0030] The electronic balance is a precision balance, which includes a balance body 7 and a balance tray 8 arranged on the balance body 7 . The balance body 8 is arranged below the output end of the horizontally pulled belt conveyor 2 , and the weighing tray 3 is placed on the balance tray 8 .

[0031] The width of the weighing tray 3 is greater than the belt width of the horizontally stretched belt conveyor 2 , ensuring that the weighing tray 3 can completely receive the tobacco output from the horizontally stretched belt conveyor 2 and prevent part of the tobacco from falling outside the weighing tray 3 .

[0032] The belt width of the horizontal belt conveyor 2 is greater than the belt width of the lifting belt conveyor 1, ensuring that the horizontal belt conveyor 2 can completely receive the tobacco output from the lifting belt conveyor 1 and prevent part of the tobacco from falling outside the two sides of the horizontal belt conveyor 2.

[0033] When this embodiment is used, tobacco is put into the hopper 5, and the tobacco is supported on the belt of the lifting belt conveyor 1. The lifting belt conveyor 1 and the horizontally pulled belt conveyor 2 are working, and the lifting ribs 4 can separate the tobacco evenly and effectively lift the tobacco. When the tobacco is lifted from bottom to top along with the lifting ribs 4, due to the inclined setting of the lifting belt conveyor 1, the tobacco higher than the lifting ribs 4 can slide down under the action of its own weight, and then when two adjacent lifting ribs 4 move from bottom to top to the upper end of the lifting belt conveyor 1, the tobacco between the two adjacent lifting ribs 4 is flush with the upper side edges of the two adjacent lifting ribs 4, ensuring that the volume of tobacco output by the lifting belt conveyor 1 each time is the same, and the tobacco is more accurately and evenly provided to the horizontally pulled belt conveyor 2 in batches, and the horizontally pulled belt conveyor 2 can separate the tobacco. The batches of tobacco are evenly stretched, and the belt conveyor 2 is stretched horizontally, and then the evenly stretched tobacco is uniformly conveyed to the weighing tray 3. The weighing tray 3 receives the tobacco and weighs it with an electronic balance. The electronic balance is a precision balance to ensure that the weight error is within the specified range. When the weight of the tobacco weighed by the weighing tray 3 reaches the requirement, the lifting belt conveyor 1 and the horizontally stretched belt conveyor 2 stop running, the weighing tray 3 is manually removed, and the tobacco in the weighing tray 3 is poured out and provided to the filling process. Then, the weighing tray 3 is put back in place and the lifting belt conveyor 1 and the horizontally stretched belt conveyor 2 are started. The weighing tray 3 continues to receive the tobacco, with high weighing accuracy and high weighing efficiency, which improves the filling efficiency, has a high degree of mechanization, low labor intensity, low labor cost, avoids tobacco pollution, and ensures the test results.

[0034] Example 2

[0035] On the basis of Example 1, the weighing tray 3 includes a C-shaped plate with the open side facing downward, and a downwardly concave tray body is integrally formed in the middle of the upper side plate of the C-shaped plate, and the tray body is located directly below the output end of the horizontally pulled belt conveyor 2. The bottom of the tray body is higher than the lower side edges of the two side plates of the C-shaped plate, and the lower side edges of the two side plates of the C-shaped plate are supported on the balance tray 8. The width of the tray body is greater than the belt width of the horizontally pulled belt conveyor 2, ensuring that the tobacco can completely fall from the horizontally pulled belt conveyor 2 into the tray body. The weighing tray 3 is simple to manufacture, low in cost, and can be integrally die-cast.

[0036] Among them, the disk body is a trough structure such as a V-shaped trough body, a trapezoidal trough body, a U-shaped trough body, a C-shaped trough body, a hemispherical trough body or a hemispherical trough body that is concave and larger at the top and smaller at the bottom.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
