Description

TECHNICAL FIELD

[0001] The utility model relates to a cut tobacco conveying equipment technical field, especially a cut tobacco loosening device. BACKGROUND

[0002] In the cut tobacco production line of tobacco industry, in order to improve the uniformity of cut tobacco processing quality, guarantee the quality of cut tobacco, the vibration tank is generally arranged after cutting, after curing and before winnowing to loosen and convey the bunched, wound and adhered cut tobacco, so that the cut tobacco is handled in subsequent processing, thereby guaranteeing the quality of product.

[0003] But in actual production process, the effect of loosening the bunched, wound and adhered cut tobacco in the conveying process by only relying on the vibration tank is poor, and the cut tobacco entering the vibration tank through the feeding port is prone to accumulate in the middle of the vibration tank (see the area shown by point Q in the middle), so that the cut tobacco is difficult to spread on the vibration tank, the cut tobacco is unevenly dispersed, and the probability of blocking in subsequent process is increased. Figure 1 UTILITY MODEL CONTENT

[0004] The utility model discloses a cut tobacco loosening device, which can loosen the cut tobacco and make the cut tobacco more evenly distributed in the conveying process, thereby avoiding the blocking caused by bunched accumulation in subsequent process, guaranteeing the uniformity of material, and further improving the quality of product.

[0005] To solve the above technical problems, the embodiment of the utility model discloses a cut tobacco loosening device, which comprises:

[0006] The vibration tank is used for vibrating and conveying cut tobacco, and the two ends of the vibration tank are respectively a feeding port and a discharging port.

[0007] The two combing plates are arranged on the conveying surface of the vibration tank in a V shape, the extension direction of the combing plate has an included angle with the conveying direction of the cut tobacco, one end of the combing plate close to the feeding port is a connecting end, and the other end close to the discharging port is a guide end, the connecting ends of the two combing plates are connected, the guide ends of the two combing plates have an opening therebetween, the opening faces the discharging port, and the combing plates are provided with comb teeth.

[0008] ​According to the technical scheme, on one hand, the two combing plates are arranged on the conveying surface of the vibrating trough, so that when the material passes through the combing plates in the vibrating conveying process, a part of the tobacco bunches is collided with the top of the combing teeth of the combing plates due to the blocking effect of the combing plates and the fluctuation and tumbling effect of the vibrating trough, and another part of the tobacco bunches is loosened due to the friction, extrusion and pulling effect of the gap between the combing teeth, so that the tobacco becomes loose. On the other hand, the two combing plates are arranged in a V shape, and the opening between the material guiding ends of the two combing plates faces the discharge port, so that a part of the tobacco can be divided into two streams in the conveying process, thereby avoiding the accumulation of the tobacco in the middle of the vibrating trough, improving the uniformity of the tobacco distribution, and improving the quality of the product.

[0009] Optionally, the two combing plates are arranged in mirror image along the geometric center line of the conveying surface of the vibrating trough, a first included angle is formed between the combing plate and the conveying surface of the vibrating trough, and the distance between the combing plate and the conveying surface of the vibrating trough gradually increases in the conveying direction of the tobacco.

[0010] According to the technical scheme, the side of the two combing plates facing the feeding port is a flow guiding surface. In the conveying process, the tobacco with a height lower than the two combing plates can gradually flow to the material guiding end along the flow guiding surface, thereby avoiding the accumulation of the tobacco in the middle of the vibrating trough, and making the tobacco gradually spread in the conveying process, so that the material can be uniformly dispersed.

[0011] Optionally, the first included angle is 45-55°.

[0012] According to the technical scheme, by adjusting the range of the first included angle, the conveying speed of the tobacco bunches passing through the combing plates can be reduced, so that the tobacco can slowly climb along the two combing plates under the fluctuation and tumbling effect of the vibrating trough, the pulling and loosening time of the tobacco bunches and the combing teeth is prolonged, the loosening efficiency of the combing plates on the tobacco bunches is improved, and the poor or excessive flow guiding effect of the combing plates on the tobacco to the two sides of the combing plates due to the improper size of the first included angle is avoided, and the uneven dispersion of the tobacco entering the discharge port is avoided.

[0013] Optionally, the connection between the two combing plates and the vibrating trough forms two connection lines, a second included angle is formed between the two connection lines, and the second included angle is 130-140°.

[0014] Optionally, the upper end of the combing tooth is in a circular arc shape.

[0015] According to the technical scheme, when the tobacco bunches pass through the upper end of the combing tooth, the tobacco bunches collide with the top of the combing tooth due to the fluctuation and tumbling effect of the vibrating trough, and the circular arc shape of the upper end of the combing tooth can reduce the tobacco breakage while ensuring the loosening effect, thereby reducing the loss of the tobacco.

[0016] Optionally, the width of the combing tooth is 45-55 mm, and the gap width between the two adjacent combing teeth is 35-45 mm.

[0017] By adopting the above technical solution, the appropriate gap width between two adjacent comb teeth can be used to squeeze, pull and rub the tobacco, thereby ensuring the looseness of the tobacco clump; at the same time, it can avoid excessive tobacco clogging in the gap due to too small a gap, thereby ensuring the normal delivery of tobacco.

[0018] Optionally, along the width direction of the vibrating groove, the spacing between the sides of the two vibrating grooves and the two adjacent comb plates is 350-450 mm.

[0019] Optionally, the height of the comb plate gradually decreases from the connecting end to the guiding end, with the height difference between the highest point of the connecting end and the conveying surface of the vibrating trough being 90mm, and the height difference between the highest point of the guiding end and the conveying surface of the vibrating trough being 60mm.

[0020] Optionally, the connection between the two comb plates can be formed by welding or bending, and the connection between the two comb plates and the vibrating groove can be formed by bolting.

[0021] Using the above technical solution, the connecting ends of the two comb plates fit tightly together, preventing tobacco from clogging between the two comb plates during the conveying process and reducing tobacco loss. The two comb plates are connected to the vibrating groove by bolts, facilitating the disassembly, cleaning, and replacement of the comb plates.

[0022] Optionally, both comb plates are made of stainless steel.

[0023] By adopting the above technical solution and setting the material of the two comb plates to stainless steel, the wear resistance of the comb plates can be enhanced and the service life of the comb plates can be extended. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0038] See Figure 1 The present invention discloses a tobacco loosening device, comprising:

[0039] Vibrating trough 1 is used for vibrating and conveying tobacco shreds. The two ends of vibrating trough 1 are the feed inlet 101 and the discharge outlet 102, respectively.

[0040] Two comb plates 2 are arranged in a V-shape on the conveying surface 11 of the vibrating trough 1. The extending direction of the comb plates 2 is the same as the conveying direction of the tobacco shreds (e.g., ...). Figure 1 and Figure 2 There is an included angle between the two comb plates 2 (as shown in the X direction). The end of the comb plate 2 near the feed inlet 101 is the connecting end 201, and the end near the discharge outlet 102 is the guiding end 202. The connecting ends 201 of the two comb plates 2 are connected. There is an opening between the guiding ends 202 of the two comb plates 2, and the opening faces the discharge outlet 102. Both comb plates 2 are provided with comb teeth 21.

[0041] By adopting the above technical solution, on the one hand, by setting two comb plates 2 on the conveying surface 11 of the vibrating trough 1, when the material passes through the comb plates 2 during the vibrating conveying process, some tobacco clumps are loosened by the obstruction of the comb plates 2 and the undulating and bumping action of the vibrating trough 1, and collide with the top of the comb teeth 21 on the comb plates 2. Other tobacco clumps are loosened by the friction, compression and pulling action of the gaps between the comb teeth 21, making the tobacco shreds loose. On the other hand, by setting the two comb plates 2 in a V-shape, and with the opening between the guide ends 202 of the two comb plates 2 facing the discharge port 102, some tobacco shreds can be diverted to both sides of the two comb plates 2 during the conveying process, avoiding the accumulation of tobacco shreds in the middle of the vibrating trough 1, improving the uniformity of tobacco shred distribution, and thus improving the quality of the product.

[0042] Furthermore, the two comb plates 2 are aligned along the geometric center line of the conveying surface 11 of the vibrating groove 1 (e.g., Figure 1 and Figure 2 As shown in line AA, the comb plate 2 and the conveying surface 11 of the vibrating groove 1 form a first included angle (as shown in line AA).Figure 4 The distance between the two combing plates 2 and the conveying surface 11 of the vibrating trough 1 gradually increases along the conveying direction of the tobacco shreds.

[0043] According to the above technical solution, the side of the two combing plates 2 facing the feeding port 101 is a flow guide surface 22. During the conveying process, the tobacco shreds with a low pile height can gradually flow to the guide end 202 along the flow guide surface 22, avoiding the accumulation of the tobacco shreds in the middle of the vibrating trough 1, so that the tobacco shreds can be gradually laid flat during the conveying process, thereby making the material uniformly dispersed.

[0044] Specifically, the first included angle is 45-55°. In an embodiment of the present application, the first included angle is 49.5°.

[0045] According to the above technical solution, by adjusting the range of the first included angle, the conveying speed of the tobacco shreds through the combing plate 2 can be reduced, so that the tobacco shreds can slowly climb along the two combing plates 2 under the bumping action of the vibrating trough 1, the pulling and loosening time of the tobacco shreds and the comb teeth 21 is prolonged, and the loosening efficiency of the combing plate 2 on the tobacco shreds is improved. In addition, the first included angle is not too large or too small, which can avoid poor or excessive flow guiding effect of the combing plate 2 on the tobacco shreds to the two sides of the combing plate 2, and avoid uneven dispersion of the tobacco shreds entering the discharge port 102. The applicant has found that when the first included angle is 49.5°, the combing plate 2 can have excellent loosening performance and flow guiding performance.

[0046] Further, the connection between the two combing plates 2 and the vibrating trough 1 forms two connection lines 203, and a second included angle (as shown by □β in Figure 6 The second included angle is 130-140°. In an embodiment of the present application, the second included angle is 135°.

[0047] Further, the connection between the connection ends 201 of the two combing plates 2 forms a second connection line 204, and a third included angle (as shown by ∠γ in Figure 4 The third included angle is 45°. In an embodiment of the present application, the third included angle is 45°.

[0048] Further, referring to Figure 5 The upper end of the comb tooth 21 is arc-shaped. In an embodiment of the present application, the upper end of the comb tooth 21 is a semicircular arc with a diameter of 50 mm.

[0049] According to the above technical solution, the tobacco shreds are impacted on the top of the comb tooth 21 under the bumping action of the vibrating trough 1 when passing through the upper end of the comb tooth 21, and the arc-shaped upper end of the comb tooth 21 can reduce the tobacco shreds crushing while ensuring the loosening effect, thereby reducing the loss of the tobacco shreds.

[0050] Further, the width of the comb tooth 21 ranges from 45 to 55 mm, and the gap width between the adjacent two comb teeth 21 ranges from 35 to 45 mm. In an embodiment of the present application, for example, the width of the comb tooth 21 is 50 mm, and the gap width between the adjacent two comb teeth 21 is 40 mm.

[0051] By using the above technical scheme, the tobacco can be extruded, pulled and rubbed by the appropriate gap width between the adjacent two comb teeth 21, so as to ensure the loosening effect of the tobacco bunch; and the excessive tobacco can be prevented from being blocked in the gap due to the too small gap width, so as to ensure the normal conveying of the tobacco. The applicant has found that when the width of the comb tooth 21 is 50 mm and the gap width between the adjacent two comb teeth 21 is 40 mm, the loosening effect of the tobacco bunch is the best, and the tobacco will not be blocked in the gap of the comb tooth 21.

[0052] Further, along the width direction of the vibrating groove 1 (as indicated by the Y direction in FIG. 1), the distance between the side edge 12 of the two vibrating grooves 1 and the adjacent two combing plates 2 ranges from 350 to 450 mm. In an embodiment of the present application, for example, the distance between the side edge 12 of the two vibrating grooves 1 and the adjacent two combing plates 2 is 400 mm. Figure 1 and Figure 2 Further, the height of the combing plate 2 gradually decreases from the connecting end 201 to the material guiding end 202, the height difference between the highest point of the connecting end 201 and the conveying surface 11 of the vibrating groove 1 is 90 mm, and the height difference between the highest point of the material guiding end 202 and the conveying surface 11 of the vibrating groove 1 is 60 mm. In an embodiment of the present application, for example, the comb tooth 21 is arc-shaped at the upper end and rectangular at the lower part. From the connecting end 201 to the material guiding end 202 of the combing plate 2, the length of the convex part of each comb tooth 21 is 64 mm, 58 mm, 51 mm, 44 mm and 37 mm in sequence, and the width is 50 mm. The material guiding end 202 is rectangular, the length of the convex part thereof is 53 mm, and the width is 100 mm.

[0053] Further, the connecting mode between the connecting ends 201 of the two combing plates 2 is welding or bending formation, and the connecting mode between the two combing plates 2 and the vibrating groove 1 is bolt connection. In an embodiment of the present application, for example, the combing plate 2 has a bottom plate 23, a plurality of connecting holes 4 are formed in the bottom plate 23, and the combing plate 2 is tightly attached to the conveying surface 11 of the vibrating groove 1 through the bottom plate 23.

[0054] Further, the connecting mode between the connecting ends 201 of the two combing plates 2 is welding or bending formation, and the connecting mode between the two combing plates 2 and the vibrating groove 1 is bolt connection. In an embodiment of the present application, for example, the combing plate 2 has a bottom plate 23, a plurality of connecting holes 4 are formed in the bottom plate 23, and the combing plate 2 is tightly attached to the conveying surface 11 of the vibrating groove 1 through the bottom plate 23.

[0055] The connecting end 201 of the two filleting plates 2 is closely fitted, so that the tobacco is prevented from being blocked between the two filleting plates 2 during the conveying process, and the loss of the tobacco is reduced. The two filleting plates 2 are connected with the vibrating groove 1 through the bolts 3, so that the filleting plates 2 are convenient to disassemble, clean and replace.

[0056] Further, the two filleting plates 2 are both made of stainless steel. In an embodiment of the present application, the bottom plate 23 is also made of stainless steel. The filleting plate 2 is made of a stainless steel plate with a thickness of 5 mm, and the bottom plate 23 is made of a stainless steel plate with a thickness of 6 mm.

[0057] According to the above technical scheme, the material of the two filleting plates 2 is set to be stainless steel, so that the wear resistance of the filleting plates 2 is enhanced, and the service life of the filleting plates 2 is prolonged.

[0058] Although the present application has been illustrated and described with reference to certain preferred embodiments thereof, it should be understood by the skilled in the art that the foregoing is a further detailed description of the present application in connection with specific embodiments, and the specific implementation of the present application is not limited to these descriptions.
