[0002] In the related art, a tobacco feeder has a feeding nail curtain, which includes a lifting belt 1', a plurality of nail rakes 2' and a guard plate 3'. The lifting belt 1' extends along a lifting direction that is an acute angle with the horizontal direction. The lifting belt 1' has guard plates 3' on both sides in its width direction. The guard plates 3' can prevent tobacco from falling from the lifting belt 1' in the width direction. A plurality of nail rakes 2' are arranged on the lifting belt 1' at intervals along the lifting direction. The nail rake 2' has a plurality of rakes arranged at intervals along the width direction. The plurality of nail rakes can prevent tobacco from sliding in the opposite direction of the lifting direction and causing material accumulation. However, during the operation of the tobacco feeder, tobacco often swirls and clumps on both sides in the width direction of the lifting belt 1'. After the clumped tobacco is transported to the next cutting process, the tobacco thread structure is unstable, which in turn affects the quality of cigarette making. Summary of the invention

[0003] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the utility model is to provide a feeding nail curtain, which can prevent the tobacco shreds from spinning into balls.

[0010] Preferably, the spike rake assembly also includes a third spike rake extending along the first direction, the third spike rake is inserted between the adjacent first spike rake and second spike rake, the third spike rake has baffles at both ends in the first direction, the baffles form an angle with the lifting belt on a plane perpendicular to the first direction, and the second spike rake is shorter than the third spike rake in the first direction.

[0011] Preferably, there are multiple groups of rake assemblies, and the multiple groups of rake assemblies are spaced apart along the second direction.

[0012] Preferably, the baffle has two acute edges in a plane perpendicular to its thickness, one of which is located in the plane where the lifting belt is located, and the other forms an acute-angled groove with the guard plate that opens upward.

[0013] Preferably, the first rake has protrusions at both ends in the first direction, and in a third direction orthogonal to the first direction and the second direction, the height of the protrusions is lower than the height of the baffle.

[0035] In addition, in the description of the present invention, unless otherwise specified, “plurality” means two or more.

[0036] like Figures 1 to 5 FIG. 1 is an embodiment of a feeding nail curtain 100 of the present utility model.

[0037] The feeding spike curtain 100 of this embodiment includes a lifting belt 1 and a spike rake assembly. The lifting belt 1 is suitable for being arranged between two guard plates of the feeder, the spacing direction of the two guard plates is a first direction, the lifting belt 1 extends along a second direction orthogonal to the first direction, the spike rake assembly is connected to the lifting belt 1, the spike rake assembly includes a plurality of spike rakes arranged at intervals along the second direction, each of the plurality of spike rakes extends along the first direction, the plurality of spike rakes include a plurality of first spike rakes 21, a plurality of second spike rakes 22, one or more second spike rakes 22 are arranged at intervals between two adjacent first spike rakes 21, and the second spike rakes 22 are shorter than the first spike rakes 21 in the first direction.

[0038] Specifically, Figure 1 As shown, the feeding spike curtain includes a lifting belt 1 and a spike rake assembly. The lifting belt 1 is suitable for being arranged between two guard plates of the feeder. The spacing direction of the two guard plates is the left-right direction, that is, the first direction is the left-right direction. The lifting belt 1 extends along the front-to-back direction, that is, the second direction is the front-to-back direction. The spike rake assembly is connected to the lifting belt. The spike rake assembly includes a plurality of spike rakes arranged at intervals along the front-to-back direction. Each of the plurality of spike rakes extends along the left-to-right direction. The plurality of spike rakes include a plurality of first spike rakes 21 and a plurality of second spike rakes 22. One or more second spike rakes 22 are arranged at intervals between two adjacent first spike rakes 21 in the front-to-back direction. The second spike rake 22 is shorter than the first spike rake 21 in the left-to-right direction.

[0039] By arranging the second rakes 22 between adjacent first rakes 21 and making the second rakes 22 shorter than the first rakes 21 in the left-right direction, a retreat position can be provided between the end of the first rake 21 and the end of the second rake 22 adjacent thereto. When the tobacco shreds move on the lifting belt 1 relative to the guard plate, the tobacco shreds on the left and right sides of the lifting belt 1 are subjected to friction and compression from the guard plate and can retreat to the retreat position, thereby preventing the tobacco shreds on both sides of the lifting belt 1 from being subjected to a large friction force from the guard plate due to excessive compression force, and causing the tobacco shreds to swirl into a ball.

[0040] By making the first spike rake 21 longer than the second spike rake 22 in the left-right direction, the tobacco shreds at the retreat position can stop at the end of the first spike rake 21 that is longer than the second spike rake 22, thereby preventing the tobacco shreds from sliding down and accumulating.

[0041] Therefore, the feeding nail curtain 100 of the embodiment of the utility model can not only avoid the accumulation of tobacco shreds, but also prevent the tobacco shreds from swirling into balls, thereby stabilizing the shredded structure of the tobacco shreds after the shredding process and ensuring the quality of cigarette making.

[0042] In the description of the present utility model, it should be understood that the second spike rake 22 is shorter than the first spike rake 21 in the left-right direction, which means that on a straight line extending in the left-right direction, the projection of the second spike rake 22 on the straight line completely overlaps with the projection of the first spike rake 21 on the straight line, and the first spike rake 21 has a portion that does not overlap with the projection of the second spike rake 22 on the straight line. For example, the first spike rake 21 has a first end and a second end in the left-right direction, one of the two ends of the second spike rake 22 is flush with the first end of the first spike rake 21, and the other end is close to the second end of the first spike rake 21, and the length of the second spike rake 22 in the left-right direction is less than the length of the first spike rake 21 in the left-right direction; it can also be that both ends of the second spike rake 22 in the left-right direction are close to the end of the first spike rake 21, and the length of the second spike rake 22 in the left-right direction is less than the length of the first spike rake 21 in the left-right direction.

[0043] When the feeding nail curtain 100 is installed on the feeder, the extension direction of the lifting belt 1 of the feeding nail curtain 100 forms an angle with the horizontal plane, and the feeder can transport the tobacco on the feeding nail curtain 100 obliquely upward from a low place to a high place. At this time, in order to avoid the tobacco in the retreat position from piling up because the tobacco at its lower end cannot withstand the sliding force of the upper tobacco on the lifting belt 1, preferably, the number of the multiple second nail rakes 22 between two adjacent first nail rakes 21 is less than or equal to five.

[0044] Preferably, both ends of the second rake 22 in the first direction are located in the middle of the first rake 21 , and the shortest distances from both ends of the second rake 22 to the end of the first rake 21 are equal.

[0045] Specifically, Figure 1As shown, the first spike rake 21 and the second spike rake 22 both have a left end and a right end in the left-right direction, and the relative position of the second spike rake 22 and the first spike rake 21 can make the distance from the left end of the second spike rake 22 to the left end of the first spike rake 21 equal to the distance from the right end of the second spike rake 22 to the right end of the first spike rake 21. In this way, the retreat distance between the left end of the first spike rake 21 and the left end of the second spike rake 22 is equal to the retreat distance between the right end of the first spike rake 21 and the right end of the second spike rake 22. When the tobacco shreds on the left and right sides of the lifting belt 1 are squeezed and rubbed by the guard plate, it can be avoided that one side of the two sides of the lifting belt 1 has a large friction force and turns into a ball, thereby stabilizing the shredded structure of the tobacco shreds after the shredding process and ensuring the quality of cigarette making.

[0046] Preferably, the second rake 22 includes a base 221 extending along the first direction and a plurality of rake nails 222 arranged at intervals along the first direction, the plurality of rake nails 222 are connected to the base 221 , and the plurality of rake nails 222 are all located in the middle of the base 221 in the first direction.

[0047] Specifically, Figure 1 and 3 As shown, the second nail rake 22 includes a base 221 extending in the left-right direction and a plurality of rake nails 222 arranged at intervals in the left-right direction, the plurality of rake nails 222 are connected to the base 221, and the plurality of rake nails 222 are all located in the middle of the base 221 in the left-right direction. In other words, the plurality of rake nails 222 are all located in the area except the two ends of the base 221 in the left-right direction. Since the base 221 is lower than the rake nails 222 in the up-down direction, the tobacco shreds located on the left and right sides of the lifting belt 1 are subjected to friction and compression by the guard plate, and the upper section of the tobacco shreds at the end of the first nail rake 21 can retreat to between the end face of the base 221 and the rake nails 222 close to the end face of the base 221, that is, the end of the base 221, thereby reducing the friction force of the tobacco shreds on the left and right sides of the lifting belt 1 at the end of the second nail rake 22, thereby preventing the tobacco shreds from spinning into a ball due to the large friction force, thereby stabilizing the shredded structure of the tobacco shreds after the shredding process and ensuring the quality of cigarette making.

[0048] Preferably, the spike rake assembly also includes a third spike rake 23 extending along the first direction, the third spike rake 23 is inserted between the adjacent first spike rake 21 and second spike rake 22, and the third spike rake 23 has baffles 231 at both ends in the first direction. On a plane perpendicular to the first direction, the baffles 231 form an angle with the lifting belt 1, and the second spike rake 22 is shorter than the third spike rake 23 in the first direction.

[0049] Specifically, Figure 1 and 4As shown, the nail rake assembly also includes a third nail rake 23 extending in the left-right direction, the third nail rake 23 is inserted between the adjacent first nail rake 21 and second nail rake 22, the third nail rake 23 includes an angle steel 232, a plurality of rake nails 222 and two baffles 231, the angle steel 232 extends in the left-right direction, the angle steel 232 has a first plate 2321 and a second plate 2322 forming a V-shaped groove, a plurality of rake nails 222 are arranged on the first plate 2321 at intervals in the left-right direction, the two baffles 231 are respectively connected to the two ends of the second plate 2322, on a plane perpendicular to the left-right direction, the baffle 231 forms an angle with the lifting belt 1, and the second nail rake 22 is shorter than the third nail rake 23 in the left-right direction.

[0050] On a plane perpendicular to the left-right direction, by forming an angle between the baffle 231 and the lifting belt 1, the second spike rake 22 is shorter than the third spike rake 23 in the left-right direction. When the feeder is working, the third spike rake 23 can stop the tobacco shreds sliding down from above it, thereby preventing the tobacco shreds located at the upper section of the third spike rake 23 of the feeding spike curtain 100 from entering the tobacco shreds located at the lower section of the third spike rake 23 of the feeding spike curtain 100, thereby ensuring the uniformity of the tobacco shreds.

[0051] Preferably, there are multiple groups of rake assemblies, and the multiple groups of rake assemblies are arranged at intervals along the second direction. When the feeder needs to convey more tobacco shreds and needs to lengthen the feeding nail curtain 100, the purpose of lengthening the feeding nail curtain 100 can be achieved by arranging multiple groups of rake assemblies at intervals along the conveying direction of the lifting belt 1.

[0052] Preferably, the baffle 231 has two acute edges in a plane perpendicular to its thickness, one of which is located in the plane where the lifting belt 1 is located, and the other forms an acute-angled groove with the guard plate that opens upward.

[0053] Specifically, Figure 1 and 5 As shown, the baffle 231 has a first acute-angled edge 2311 and a second acute-angled edge 2312 on a plane perpendicular to the front-rear direction, the second acute-angled edge 231 is located in the plane where the lifting belt 1 is located, and the first acute-angled edge 2311 and the guard plate form an upwardly opening and acute-angled groove. By locating the second acute-angled edge 2312 in the plane where the lifting belt 1 is located, the baffle 231 can stop the tobacco shreds to the greatest extent in the left-right direction to prevent them from sliding. By forming an upwardly opening and acute-angled groove with the first acute-angled edge 2311 and the guard plate, when the baffle 231 is at the highest point, the baffle 231 can be prevented from interfering with the side guard belt that prevents the tobacco shreds from falling in the left-right direction.

[0054] Preferably, the first rake 21 has protrusions at both ends in the first direction, and in a third direction orthogonal to the first direction and the second direction, the protrusions are lower than the baffle 231 .

[0055] Specifically, Figure 1 and Figure 2 As shown, the first nail rake 21 includes an angle steel 232 extending in the left-right direction and a plurality of rake nails 222 arranged at intervals in the left-right direction. The angle steel 232 has a first plate 2321 and a second plate 2322 forming a V-shaped groove. The plurality of rake nails 222 are connected to the first plate 2321 of the angle steel. The second plate 2322 of the angle steel forms a protrusion extending in the left-right direction, and the protrusion is lower than the baffle plate 231 in the vertical direction. When the tobacco shreds on both sides of the lifting belt 1 are subjected to friction and compression by the guard plate, the upper section of the tobacco shreds at the end of the first nail rake 21 can retreat to the upper end of the protrusion, which can prevent the tobacco shreds from spinning and forming a ball due to excessive friction when the tobacco shreds are subjected to force. At the same time, the protrusion can also prevent the tobacco shreds at the upper section of the end of the first nail rake 21 of the feeding nail curtain 100 from sliding off and causing tobacco shreds to accumulate, thereby stabilizing the shredded structure of the tobacco shreds after the shredding process and ensuring the quality of cigarette making.

[0056] Based on the above-mentioned feeding nail curtain, the embodiment of the utility model also proposes a tobacco feeder. The tobacco feeder of this embodiment includes a lifting and conveying mechanism, two guard plates and a feeding nail curtain 100. The lifting and conveying mechanism is connected to the feeding nail curtain 100 so that the feeding nail curtain 100 can convey tobacco. The two guard plates are arranged at intervals on both sides of the feeding nail curtain 100 in the width direction. The feeding nail curtain 100 is the feeding nail curtain 100 mentioned above in this embodiment. The tobacco feeder with the feeding nail curtain 100 can avoid tobacco accumulation and prevent tobacco from spinning into a ball, thereby stabilizing the tobacco wire structure after the cutting process and ensuring the quality of cigarette making.

[0057] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
