Tobacco blending is the process of accurately and evenly blending stem shreds, expanded shreds, etc. into dry tobacco online according to the product formula design requirements. It is a key process to achieve uniform content of each component of tobacco. The uniformity of material mixing during tobacco blending has an important impact on subsequent flavoring and even rolling and finished product quality.

[0003] In the process of silk production, in order to ensure the accuracy and uniformity of subsequent material blending, an electronic belt scale is installed at the feeding end of the belt conveyor. The electronic belt scale measures the instantaneous flow of tobacco in real time, and adjusts the feeding flow of the belt conveyor according to the measurement results of the electronic belt scale, so that the tobacco falls on the belt conveyor according to the preset flow. However, in actual production, the discharge port of the electronic belt scale is located above the feeding port of the belt conveyor, and the vertical drop between the two is relatively large. When the material is transported to the feeding port of the belt conveyor through the feeding port of the electronic belt scale, the tobacco is easily entangled, so it will cause the tobacco to fall into a group and fall to the belt conveyor, causing the flow of tobacco entering the blending process to be unstable, thereby affecting the accuracy and uniformity of material blending, and having a great impact on the quality, qualified rate and overall quality of the batch product processing process.

For ordinary technicians in this field, the specific meanings of the above terms in this embodiment can be understood according to specific circumstances.

[0030] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] like Figure 1 As shown, the embodiment of the utility model provides a diversion and material sizing device, which is arranged on a belt conveyor 1, and the conveying direction of the belt conveyor 1 is a first direction (such as Figure 1 The width direction of the belt conveyor 1 is the second direction (as shown in the X direction). Figure 1 The guide and material sparging device includes: a fixing frame 3 and two guide plate assemblies 4.

[0032] Specifically, the fixing frame 3 includes a frame body 31 and at least one mounting plate 32 . The frame body 31 spans above the belt conveyor 1 along the Y direction, and the mounting plate 32 is parallel to the upper surface of the belt conveyor 1 .

[0033] Two guide plate assemblies 4 are arranged below the mounting plate 32 at intervals along the Y direction. Each guide plate assembly 4 includes a rotating guide plate 41 and a sliding guide plate 42 arranged in sequence along the X direction. The two rotating guide plates 41, the two sliding guide plates 42, the lower surface of the mounting plate 32 and the upper surface of the belt conveyor 1 together enclose a conveying channel, which is used to convey materials; wherein the sliding guide plate 42 extends along the first direction, the extending direction of the rotating guide plate 41 has a certain angle with the X direction, and the spacing between the two rotating guide plates 41 gradually decreases along the X direction.

[0034] The applicant has fully considered the problems that arise before the material enters the blending process during the silk production process. By enclosing two rotating guide plates 41, two sliding guide plates 42, the lower surface of the mounting plate 32 and the upper surface of the belt conveyor 1 together to form a conveying channel, the material can pass through the conveying channel during the conveying process. Since the cross-sectional area of ​​the outlet end of the conveying channel is constant, the material flow rate output by the conveying channel is constant, thereby improving the stability of the material flow rate entering the blending process. In addition, there is a certain angle between the extension direction of the rotating guide plate 41 and the conveying direction of the belt conveyor 1, which can make the opening area of ​​the feed end between the two rotating guide plates 41 larger than the opening area of ​​the discharge end, so that the material on the belt conveyor 1 can be gathered, thereby reducing the accumulation of materials at the edge of the belt 11 and reducing the consumption of materials.

[0035] Further, refer to Figure 2 and Figure 3 , the two ends of the rotating guide plate 41 in its extension direction are respectively a feed end 412 and a first connection end 413, and along the X direction, the first connection end 413 is located at the downstream side of the feed end 412;

[0036] The two ends of the sliding guide plate 42 in the extension direction thereof are respectively a second connection end 424 and a discharge end 425. Along the X direction, the discharge end 425 is located at the downstream side of the second connection end 424;

[0037] The feed end 412 is hinged to the mounting plate 32 , the first connection end 413 and the second connection end 424 are hinged, and the sliding guide plate 42 can slide relative to the mounting plate 32 along the X direction and the Y direction to change the distance between the two sliding guide plates 42 .

[0038] In a specific implementation, the upper end surface of the rotating guide plate 41 is provided with a first threaded hole 411, and the mounting plate 32 is provided with an arc-shaped sliding hole 322 corresponding to a portion of the first threaded hole 411;

[0039] The upper end surface of the sliding guide plate 42 is provided with a longitudinal sliding groove 422 extending along the X direction, a slider 423 is provided in the longitudinal sliding groove 422, the slider 423 can slide in the longitudinal sliding groove 422 along the first direction, a second threaded hole 421 is provided on the slider 423, and a transverse sliding hole 321 corresponding to a part of the second threaded hole 421 and extending along the Y direction is provided on the mounting plate 32;

[0040] The guide plate assembly further includes a first bolt 43 and a second bolt 44 . The first bolt 43 passes through the mounting plate 32 and is threadedly connected to the rotating guide plate 41 . The second bolt 44 passes through the mounting plate 32 and is threadedly connected to the sliding guide plate 42 .

[0041] Specifically, when the first bolt 43 and the second bolt 44 are loosened, the slider 423 can slide along the transverse sliding hole 321 to drive the sliding guide plate 42 to slide along the Y direction; and the sliding guide plate 42 can also slide along the X direction relative to the slider 423; the sliding guide plate 42 can change the distance between the two sliding guide plates 42 during the sliding process along the X direction and the Y direction, and drive the rotating guide plate 41 to rotate around the hinge point between the rotating guide plate 41 and the mounting plate.

[0042] Furthermore, the guide and material leveling device also includes a screw rod 45, which is arranged on the mounting plate 32 and can rotate around its own axis. A first thread and a second thread are arranged in sequence along the Y direction on the circumferential surface of the screw rod 45, and the rotation directions of the first thread and the second thread are opposite. A connecting plate 324 is connected to the top of each sliding guide plate 42, and each connecting plate 324 is provided with a threaded hole 323. The screw rod 45 passes through the two threaded holes 323, and the two threaded holes 323 have different rotation directions. The threaded hole 323 on one connecting plate 324 is threadedly connected to the first thread, and the threaded hole 323 on the other connecting plate 324 is threadedly connected to the second thread.

[0043] In some embodiments, the effective lengths of the transverse sliding hole 321 , the longitudinal sliding groove 422 , the arc-shaped sliding hole 322 and the forward and reverse threads of the screw rod 45 can be adjusted according to actual needs.

[0044] Specifically, the cross-sectional area of ​​the outlet end of the conveying channel is positively correlated with the material transportation flow rate. When the material transportation flow rate changes, the cross-sectional area of ​​the current outlet end of the conveying channel may not be suitable for the material transportation flow rate. At this time, it is necessary to adjust the spacing between the two sliding guide plates 42 so that the cross-sectional area of ​​the outlet end of the conveying channel can meet the material transportation flow rate. When it is necessary to adjust the spacing between the two sliding guide plates 42, the operator first loosens the two first bolts 43 and the two second bolts 44 appropriately, and then uses a wrench to rotate one end of the screw rod 45, and relies on the positive and negative threads at both ends of the screw rod 45 to drive the two sliders 423 to slide along the transverse sliding hole 321, so that the slider 423 drives the sliding guide plate 42 to slide along the Y direction. At the same time, the sliding guide plate 42 can also slide relative to the slider 423 along the X direction. When the sliding guide plates 42 slide along the X direction and the Y direction, the distance between the two sliding guide plates 42 will increase or decrease. At the same time, the two sliding guide plates 42 will drive the two rotating guide plates 41 to rotate around the hinge point between the rotating guide plates 41 and the mounting plate. When the distance between the two sliding guide plates 42 is adjusted to the right position, the operator tightens the first bolt 43 and the second bolt 44 to fix the relative positions of the two rotating guide plates 41 and the two sliding guide plates 42, thereby completing the adjustment of the guide and material leveling device. When the material transportation flow rate changes again, the operator repeats the above operation until the material flow rate output from the outlet end of the conveying channel is relatively stable.

[0045] Furthermore, the operator can observe the material state at the outlet of the conveying channel to determine whether the spacing between the two sliding guide plates 42 can meet the material transportation flow rate. Specifically, when the material passes through the outlet of the conveying channel, it must almost fill the cross-section of the outlet of the conveying channel to keep the flow rate stable. Therefore, the operator can determine whether the spacing between the two sliding guide plates 42 can meet the material transportation flow rate by detecting the height difference between the highest point and the lowest point of the material at the outlet, and the width difference between the widest and the narrowest point. For example, in actual production, when the material transportation flow rate is 4400kg / h, if the material width dimension difference is less than 24cm and the height dimension difference is less than 15cm, it indicates whether the spacing between the two sliding guide plates 42 can meet the material transportation flow rate; when the material transportation flow rate is 2600kg / h, if the material width dimension difference is less than 20cm and the height dimension difference is less than 15cm, it indicates that the spacing between the two sliding guide plates 42 can meet the material transportation flow rate. The maximum difference in material width should be kept within 20cm, and the maximum difference in material height should be kept within 15cm.

[0046] The guide and material leveling device of the utility model can be provided with a pulley 46 at the bottom of the rotating guide plate 41 and the sliding guide plate 42. When the operator disassembles or adjusts the guide plate assembly 4, the pulley 46 can slide in contact with the upper surface of the belt 11 to avoid damaging the upper surface of the belt 11.

[0047] Furthermore, a sealing strip 47 is provided between the bottom of the rotating guide plate 41 and the sliding guide plate 42 and the upper surface of the belt 11, and the sealing strip 47 is used to prevent the material from overflowing from the conveying channel. The provision of the sealing strip 47 can ensure that the material is gathered in the conveying channel to the greatest extent.

[0048] Furthermore, the guide and material leveling device further comprises a protective cover 5 , which is disposed above the mounting plate 32 , and the protective cover 5 can cover the mounting plate 32 .

[0049] The flow-guiding and material-splitting device of the utility model can be provided with a protective cover 5 above the mounting plate 32. When debugging the flow-guiding and material-splitting device, the protective cover 5 is opened, and the staff can intuitively understand the material gathering and collecting conditions, so as to make timely adjustments to the flow-guiding and material-splitting device; when the debugging is completed, the protective cover 5 is closed, which can protect the flow-guiding and material-splitting device and keep the silk production site beautiful and tidy.

[0050] In specific implementation, one side edge of the protective cover 5 parallel to the X direction is hinged to the fixing frame 3, and the protective cover 5 is also provided with an elastic member 51, one end of the elastic member 51 is hinged to the mounting plate 32, and the other end is hinged to the protective cover 5, and the elastic member 51 is used to apply a force to the protective cover 5 away from the mounting plate 32.

[0051] The guide and material leveling device of the present invention hinges one side edge of the protective cover 5 with the fixing frame 3 and arranges an elastic member 51 between the protective cover 5 and the mounting plate 32. The operator can open the protective cover 5 with the force of the elastic member 51 to facilitate the use of the operator.

[0052] In some embodiments, the frame 52 of the protective cover 5 can be made of stainless steel, and the top plate 53 of the protective cover 5 can be made of a 4 mm thick PC endurance board. The design of the protective cover 5 can effectively ensure the structural strength and prevent the generation of condensed water inside the top plate 53 during the tobacco delivery process. Specifically, the outer surface of the top plate 53 can be pasted with a Teflon film, thereby effectively preventing dust accumulation above the top plate 53 and facilitating cleaning.

[0053] In some embodiments, the sealing strip 47 is made of food-grade silicone, which can prevent materials from overflowing the conveying channel while ensuring the quality and safety of silk production products.

[0054] Exemplarily, the elastic member 51 is a nitrogen spring. The operator can use the nitrogen spring according to actual needs to provide assistance for opening the protective cover 5, thereby reducing the labor intensity of the staff, and the nitrogen spring can provide a stable support force for the protective cover 5 when the staff maintains the diversion and sizing device to ensure the safety of the staff.
