When discharging materials, the materials in the tray flow into the receiving cavity through the feed inlet at the top of the hopper.

[0004] However, when the hopper in the prior art is connected to the tray, the materials are prone to tilt during the process of falling from the tray into the hopper, resulting in the materials being prone to disorder in the hopper, and the stability of discharging materials is poor.

[0027] The present invention provides a hopper for rod-shaped materials, which includes a hopper body, a diverter mechanism and a guide mechanism; a accommodating chamber is arranged in the hopper body, and a feed port communicating with the accommodating chamber is arranged at the top of the hopper body, and a discharge port communicating with the accommodating chamber is arranged at the bottom; the diverter mechanism is arranged at the feed port, and a diverter plate inclined downward is arranged at the top of the diverter mechanism, and the diverter plate can be lifted and arranged on the diverter mechanism; the guide mechanism is arranged in the accommodating chamber and is located at the bottom of the diverter mechanism, and separates a plurality of independent spaces in the accommodating chamber. When the material tray is unloaded, the diverter mechanism has a certain receiving function to avoid the phenomenon of material crossing and horizontally due to the lack of material below. And the diverter plate inclined downward is arranged on the top of the diverter mechanism, so that the material can be better guided to fall and the material can be avoided from tilting, so as to improve the stability of unloading. And the diverter plate can be lifted and lowered, so that the height of the diverter plate can be adjusted according to demand, so as to better receive the material and adapt to different unloading environments. In addition, the guide mechanism is also provided, through which a plurality of independent spaces are separated in the accommodating chamber, so that the materials in each area of ​​the accommodating chamber can fall evenly, avoiding the occurrence of drop in individual areas due to too fast material feeding, thereby better ensuring the stability of material feeding.

[0028] Please refer to Figures 1 to 7 In one embodiment, a hopper 100 for rod-shaped materials is provided, which is mainly used to solve the problem of unstable material discharge during the docking process between the hopper and the material tray in the prior art.

[0029] The hopper 100 for rod-shaped materials includes a hopper body 10 , a diverter mechanism 20 and a guide mechanism 30 . The hopper body 10 is mainly used to contain materials, the diverter mechanism 20 is mainly used to divert materials falling from a tray, and the guide mechanism 30 is mainly used to separate and guide the materials in the hopper body 10 .

[0030] The hopper body 10 is provided with a receiving cavity 11, and the top of the hopper body 10 is provided with a feed port 12 communicating with the receiving cavity 11, and the bottom of the hopper body 10 is provided with a discharge port 13 communicating with the receiving cavity 11. When feeding, the material in the upstream tray falls into the receiving cavity 11 through the feed port 12 for storage, and then the material in the receiving cavity 11 is transported to the downstream drum wheel in an orderly manner through the discharge port 13.

[0031] The diversion mechanism 20 is arranged at the feed inlet 12, and a downwardly inclined diversion plate 21 is arranged at the top of the diversion mechanism 20. The diversion plate 21 is arranged on the diversion mechanism 20 in a liftable manner. Since the diversion mechanism 20 is arranged at the feed inlet 12, during feeding, the diversion mechanism 20 can play a certain role in receiving the material, and the material will fall on the diversion plate 21 and then fall from the side channel of the diversion mechanism 20 under the guidance of the diversion plate 21. And since the diversion plate 21 can be lifted and lowered on the diversion mechanism 20, the height of the diversion plate 21 can be adjusted according to requirements to adapt to different materials or different feeding methods for trays.

[0032] The diversion mechanism 30 is arranged in the accommodation cavity 11 and is located at the bottom of the diversion mechanism 20, and divides the accommodation cavity 11 into a plurality of independent spaces.

[0033] It can be understood that when the hopper in the prior art is docked with the tray, the material is prone to tilt during the process of falling into the hopper, resulting in the material being prone to disorder in the hopper and poor stability of feeding. In addition, heated tobacco products are a new type of tobacco that has gradually emerged in recent years. The specifications and types of the rod materials thereof are numerous and the length is short, which is quite different from the rod materials of traditional cigarettes. The hoppers in the prior art are usually designed for the rod materials of traditional cigarettes, and when the hopper is used for the storage and output of the rod materials of heated tobacco products, the problem of unstable feeding is more obvious.

[0034] In the hopper 100 of the rod-shaped material provided in this embodiment, the diversion mechanism 20 is provided. During feeding, after part of the material falls from the material tray, it can be received by the diversion mechanism 20, and then flows to the side of the diversion mechanism 20 under the guidance of the diversion plate 21, so as to buffer and guide the falling of the material, make the material more concentrated, and avoid the height difference between the upper and lower materials caused by the direct and rapid falling of the material, so that the material has space to tilt, thereby making the feeding process more stable. The diversion plate 21 is a downwardly inclined structure with a certain angle. On the one hand, it can guide the falling material to avoid the material from tilting; on the other hand, after the material falls on the diversion plate 21, it can gradually roll downward through the diversion plate 21, and smoothly guide the material to the lower side of the receiving cavity 11. In addition, by dividing the receiving cavity 11 into multiple independent spaces through the diversion mechanism 30, the materials on each side can fall more evenly. Through the mutual cooperation of the diversion mechanism 20 and the diversion mechanism 30, it is ensured that the material on the docking surface of the hopper 100 of the rod-shaped material and the material tray (which can be a material tray for turnover feeding or a material tray for manual feeding) is uniform and flat, and there will be no obvious state of being empty on one side and full on the other side. The diversion plate 21 is liftably arranged on the diversion mechanism 20, so that the height of the diversion plate 21 can be adjusted according to actual needs, so as to better adapt to the feeding methods of different material trays (such as a material tray for turnover feeding or a material tray for manual feeding). In addition, it can also be lifted for different specifications and types of materials in heated cigarettes, so as to better adapt to the production requirements of different base rod materials of heated cigarettes.

[0035] Preferably, in one embodiment, a plurality of the diversion mechanisms 20 are provided. The plurality of the diversion mechanisms 20 are divided into side diversion mechanisms 201 located on both sides and an intermediate diversion mechanism 202 located between the two side diversion mechanisms 201. Adjacent two of the diversion mechanisms 20 are spaced apart from each other to form a material falling space. The diversion plate of the side diversion mechanism 201 is a diversion plate inclined toward one side, and the diversion plate of the intermediate diversion mechanism 202 is a diversion plate inclined toward both sides. For example, as Figure 2As shown, the diverter plate 21 on the side diverter mechanism 201 on the left side is a single-sided inclined diverter plate inclined towards the lower right, while the diverter plate 21 on the side diverter mechanism 201 on the right side is a single-sided inclined diverter plate inclined towards the lower left, and the diverter plate of the middle diverter mechanism 202 in the middle part is inclined towards both sides. Thus, the diverter plate 21 on the outermost side diverter mechanism 201 can form a guiding flow space with a wider upper part and a narrower lower part with the diverter plate 21 of an adjacent middle diverter mechanism 202, and both sides of the diverter plate 21 of the middle diverter mechanism 202 can respectively form a guiding flow space with a wider upper part and a narrower lower part with the adjacent diverter plates 21. By arranging a plurality of spaced-apart diverter mechanisms 20, on the one hand, the space at the feed inlet 12 can be further restricted to prevent the material from falling too fast and causing a height difference, resulting in inclination; on the other hand, the material can be guided to fall orderly in the material falling space separated by the diverter mechanisms 20.

[0036] More preferably, in one embodiment, a vertical plate is connected to the bottom of each diverter plate 21, and the side of the diverter mechanism 20 can be covered by the vertical plate to prevent the material from getting stuck in the diverter mechanism 20. Additionally, it can better guide the material to fall in the material falling space.

[0037] Preferably, in one embodiment, the accommodation cavity 11 is divided into an upper accommodation cavity 111 located above and a lower accommodation cavity 112 located below. The upper accommodation cavity 111 has a structure with a gradually decreasing width from top to bottom, so as to gradually guide the material downward, prevent the material from falling too fast and generating a height difference, and further prevent skew. The upper accommodation cavity 111 communicates with the lower accommodation cavity 112 through a connecting channel 1111 at the bottom. The guiding mechanism 30 is arranged in the upper accommodation cavity 111, and the guiding plate of at least one guiding mechanism 30 extends into the connecting channel 1111, so that at least two channel openings can be separated from the connecting channel 1111. For example, as Figure 2 shown, the guiding plate of the guiding mechanism 30 in the middle extends into the connecting channel 1111, thus separating the left and right channel openings of the connecting channel 1111. The material in the left space falls into the lower accommodation cavity 112 through the left channel opening, and the material in the right space falls into the lower accommodation cavity 112 through the right channel opening. In this way, the material in the upper accommodation cavity 111 is guided orderly to the lower accommodation cavity 112, so as to ensure that the material on the docking surface between the hopper 100 and the tray of the rod-shaped material is uniform and flat, and there will be no obvious state of being empty on one side and full on the other side.

[0038] Preferably, in one embodiment, the side plate 14 of the hopper body 10 includes a first side plate 141 on one side and a second side plate 142 on the other side. The second side plate 142 includes a top side plate 1421 at the upper part and a bottom side plate 1422 at the lower part. The top side plate 1421 extends obliquely downward towards the first side plate 141 and is spaced from the first side plate 141 to form the connection channel 1111. The top side plate 1421 extending obliquely downward can guide the material downward more orderly.

[0039] Specifically, in one embodiment, the hopper body 10 includes the side plate 14, the back plate 15 and a cover plate (not shown in the figure). The cover plate is spaced opposite to the back plate 15, and the side plates 14 are located on both sides between the back plate 15 and the cover plate.

[0040] Preferably, in one embodiment, three intermediate diversion mechanisms 202 are arranged in sequence. The bottom parts of the three intermediate diversion mechanisms 202 are respectively provided with the diversion mechanisms 30. The three diversion mechanisms 30 are divided into a first diversion mechanism 31, a second diversion mechanism 32 and a third diversion mechanism 33. The second diversion mechanism 32 is located in the middle, and the diversion plate of the second diversion mechanism 32 extends into the connection channel 1111. With this structure, the upper accommodation cavity 111 can be divided into two independent large spaces (I, II) by the second diversion mechanism 32, so that the material fed from one side can flow into the lower accommodation cavity 112 through one side of the connection channel 1111 via the large space I, and the material fed from the other side can flow into the lower accommodation cavity 112 through the other side of the connection channel 1111 via the large space II. The first diversion mechanism 31 can further divide two small spaces (I-1, I-2) above the large space I. Thus, after the material on one side is guided by the diversion mechanism 20 and flows into the two small spaces (I-1, I-2) respectively, it converges at the bottom of the small spaces and then flows into the lower accommodation cavity 112 through the connection channel 1111. Similarly, the third diversion mechanism 33 can also divide two small spaces (I-3, I-4) above the large space II. With this structure, the material can be divided and guided step by step from top to bottom, avoiding large height differences, so as to prevent the material from tilting and getting disordered, thereby improving the stability of material feeding.

[0041] Preferably, in one embodiment, the distance between two adjacent diversion mechanisms 20 is equal, so as to ensure that the material falling in each material falling space is more uniform.

[0042] Preferably, in one embodiment, the guide plates of the first guide mechanism 31 and the third guide mechanism 33 are rotatably arranged. Thus, when there is a deviation in the left and right falling speeds during top feeding, the guide plates of the first guide mechanism 31 (or the third guide mechanism 33) can be rotated leftward (or rightward) according to actual needs to ensure the uniformity of the feeding. The second guide mechanism 32 includes a second guide block 321 and a second guide plate 322 installed on the second guide block 321. The second guide plate 322 includes a mounting plate 3221 and an adjustable plate 3222. The mounting plate 3221 is installed on the second guide block 321, and the adjustable plate 3222 is clamped between the mounting plate 3221 and the second guide block 321 through a kidney-shaped hole. Installing the adjustable plate 3222 through the kidney-shaped hole enables the position of the adjustable plate 3222 to be adjusted according to the actual feeding situation. For example, when the feeding is uneven, the position of the adjustable plate 3222 can be adjusted according to the actual situation to adaptively adjust the widths on both sides of the connection channel 1111 and regulate the feeding speeds in the left and right large spaces.

[0043] The guide mechanism 30 is mainly used to guide the material in the upper accommodating cavity 111, and the purpose of the adjustable guide plate of the guide mechanism 30 is to make the falling speeds of the materials in the upper accommodating cavity 111 consistent, so as to ensure that the material on the docking surface between the hopper 100 of the rod-shaped material and the feeding tray (or the feeding tray for manual feeding) during flipping feeding is uniform and flat, without obvious states of being empty on one side and full on the other side, and there will be no height difference caused by some areas falling too fast during the feeding process, thus avoiding the problem of the material being disordered in the hopper.

[0044] For example, as Figure 2 shown, in order to ensure that the falling heights of the materials in the four areas of one, two, three, and four are the same, the guide plates on different guide mechanisms 30 can be adjusted. If there is a height difference between area one and area two, the widths of A and B need to be adjusted. By rotating the guide plate of the first guide mechanism 31, the guide plate is swung leftward or rightward to control the same falling speeds on both sides. Similarly, if the height difference between area three and area four is inconsistent, the widths of C and D need to be controlled, which is achieved by adjusting the guide plate on the top side plate 1421 and / or the third guide mechanism 33. If there is a height difference between area one, area two and area three, area four, the widths of X and Y need to be adjusted, which is realized through the adjustable plate 3222. After comprehensive adjustment, the materials in areas one, two, three, and four of various types of base rod materials and under various working conditions can be basically without height difference.

[0045] Since the hopper 100 of the rod-shaped material can control the uniform feeding with basically no drop in each area, preferably, in one embodiment, the hopper 100 of the rod-shaped material further includes a level detector 40, and the level detector 40 is located above the top of the hopper body 10 to detect the level height. When the level detector 40 detects an alarm indicating the need for feeding, the full-disk material loaded on the tray is conveyed to a specified position by a specific device, and then the material on the tray is poured into the hopper 100 of the rod-shaped material, thereby improving the automation production efficiency.

[0046] Preferably, in one embodiment, the hopper 100 of the rod-shaped material further includes a low-level detection mechanism 80 and a spring piece 90, and one end of the spring piece 90 extends into the accommodation cavity 11. The detection head of the low-level detection mechanism 80 faces the other end of the spring piece 90 for detecting the level condition in the accommodation cavity 11. When the material in the accommodation cavity 11 is sufficient, the material in the accommodation cavity 11 will squeeze one end of the spring piece 90, thereby causing the other end of the spring piece 90 to block the detection head of the low-level detection mechanism 80 (or leave the detection area of the detection head of the low-level detection mechanism 80); when the material in the accommodation cavity 11 is insufficient, the pressure on one end of the spring piece 90 is reduced (or no longer pressured), thereby causing the other end of the spring piece 90 to bounce up, so that the other end of the spring piece 90 leaves the detection area of the detection head of the low-level detection mechanism 80 (or blocks the detection head of the low-level detection mechanism 80). That is to say, when the material in the accommodation cavity 11 is sufficient, it will squeeze the spring piece 90, thereby causing the spring piece 90 to maintain a certain form; when the material in the accommodation cavity 11 is insufficient, it no longer squeezes the spring piece 90 (or the pressure applied to the spring piece 90 is reduced), so that the spring piece 90 can automatically bounce back to another state. And the low-level detection mechanism 80 feeds back the level condition in the accommodation cavity 11 by detecting the position of the other end of the spring piece 90. When the low-level detection mechanism 80 detects that the material in the accommodation cavity 11 is insufficient, the equipment can be shut down.

[0047] Specifically, in one embodiment, the other end of the spring piece 90 extends into the upper accommodation cavity 111 from the first side plate 141 and is located at the bottom of the upper accommodation cavity 111.

[0048] Specifically, in one embodiment, the top side plate 1421 can also adopt the adjustable structure of the waist-shaped hole type of the adjustable plate 3222.

[0049] Preferably, in one embodiment, the first flow guiding mechanism 31 includes a first flow guiding block 311 and a first flow guiding plate 312. The first flow guiding plate 312 is arranged on the first flow guiding block 311 through a rotating member 313, so that the first flow guiding plate 312 can be driven to rotate by rotating the rotating member 313. More preferably, in one embodiment, the rotating member 313 can be connected to an adjusting screw, and the adjusting screw can penetrate out from the back side of the bin body 10, so that when it is necessary to adjust the first flow guiding plate 312, the first flow guiding plate 312 can be driven to rotate online by turning the adjusting screw.

[0050] Preferably, in one embodiment, the side of the adjustable plate 3222 close to the connection channel 1111 is an arc plate, so as to better guide the base rod material and avoid bursting the base rod material.

[0051] Specifically, in one embodiment, the mounting plate 3221 is fixed to the second flow guiding block 321 by screws. When it is necessary to adjust the adjustable plate 3222, the screws can be loosened, so that the position of the mounting plate 3221 is loosened, and the adjustable plate 3222 can be moved. After the position of the adjustable plate 3222 is adjusted, the mounting plate 3221 can be tightened by tightening the screws. After tightening, the mounting plate 3221 can clamp the adjustable plate 3222 to fix the position of the adjustable plate 3222.

[0052] Specifically, in one embodiment, the third flow guiding mechanism 33 can also adopt the adjustable structure of the first flow guiding mechanism 31 or the second flow guiding mechanism 32, or can also adopt other adjustable structures, as long as the flow guiding plate of the third flow guiding mechanism 33 can be adjusted adaptively according to actual needs.

[0053] Preferably, in one embodiment, the flow splitting mechanism 20 includes a mounting block 22, a lifting drive unit 23, an inclined block 24, and the flow splitting plate 21. The lifting drive unit 23 is disposed on the mounting block 22, and the output end of the lifting drive unit 23 is connected to the inclined block 24 to drive the inclined block 24 to move. The flow splitting plate 21 is disposed on the top of the inclined block 24. When the flow splitting plate 21 needs to be adjusted in height, the lifting drive unit 23 drives the inclined block 24 to perform corresponding lifting, thereby driving the flow splitting plate 21 to adjust its position in height. The top surface of the inclined block 24 is an inclined surface that slopes downward toward the side and also slopes downward inward. The flow splitting plate 21 is attached to the top surface of the inclined block 24. That is to say, the top surface of the inclined block 24 not only slopes toward the side, but also slopes inward. And the flow splitting plate 21 is attached to the top of the inclined block 24, so that the surface of the flow splitting plate 21 for contacting the material is also an inclined surface structure that slopes toward the side and also slopes inward. As Figure 3 shown, the top surface of the inclined block 24 on the intermediate flow splitting mechanism 202 not only slopes downward to the lower left, but also slopes downward from the outside of the paper to the inside of the paper as shown in Figure 3 shown, so that the surface of the flow splitting plate 21 for contacting the material is also an inclined surface structure that slopes downward to the lower left and also slopes inward. The flow splitting plate 21 is higher on the right and lower on the left, and higher on the outside and lower on the inside. As Figure 4 shown, the top surface of the inclined block 24 on the side flow splitting mechanism 201 not only slopes downward to the lower right, but also slopes downward from the outside of the paper to the inside of the paper as shown in Figure 4 shown, so that the surface of the flow splitting plate 21 for contacting the material is also an inclined surface structure that slopes downward to the lower right and also slopes inward. The flow splitting plate 21 is higher on the left and lower on the right, and higher on the outside and lower on the inside. Through such a structure, the overall lifting structure is simpler, more compact, and the lifting is more stable.

[0054] It can be understood that in the prior art, there is a blanking method for a material tray that uses a turnover mechanism for turnover blanking. When turning over, the material will tilt forward due to inertia, resulting in a more obvious problem of unstable blanking when using the turnover method for blanking. By using the inclined block 24 with a higher outside and lower inside, and attaching the flow splitting plate 21 to the inclined block 24, the flow splitting plate 21 is also an inclined surface structure with a higher outside and lower inside. When the material tray uses the turnover method for blanking, the flow splitting plate 21 with a certain angle can better avoid the phenomenon that the material at the topmost position tilts forward and falls after turning over.

[0055] And since the flow splitting plate 21 of the flow splitting mechanism 20 can be lifted, when performing turnover blanking, the flow splitting plate 21 can be lifted, so as to stably receive the upper material and avoid the forward tilt of the material.

[0056] Specifically, in one embodiment, the bottom of the lifting drive unit 23 is fixed to the mounting block 22 by screws, and the inclined block 24 is fixed to the lifting drive unit 23 by screws. A magnet is embedded in the inclined block 24, and the diverter plate 21 is fixed to the wedge block 24 by magnet adsorption, so that the installation is stable, and at the same time, the surface of the diverter plate 21 does not need to have an additional installation structure, which will not affect the transmission of materials.

[0057] Specifically, in one embodiment, the lifting drive unit 23 is a cylinder. Different cylinder pressures (adjusted by a pressure regulating valve) can be used for different types of materials to adapt to different new tobacco materials. Of course, in other embodiments, other structures can be used for lifting, such as a spring mechanism. During the material discharge process, when the material falls more and the material squeezes the dividing plate 21, the dividing plate 21 can correspond to the squeezing spring mechanism, thereby pressing down the dividing plate 21; and when the material falls less, the spring mechanism automatically drives the dividing plate 21 to rise through its own elastic restoring force, thereby automatically adapting to the changes in the material during the falling process to avoid tilting of the material during the falling process.

[0058] Specifically, the structure of the middle diverter mechanism 202 is basically the same as that of the side diverter mechanism 201, and the only difference is the specific shapes of the diverter plate 21 and the inclined block 24. The lifting principle is basically the same, which will not be repeated here.

[0059] The diverter mechanism 20 is mainly used for the overturning device to overturn the material, and has a certain bearing effect on the material, so as to avoid the phenomenon of material crossing and sideways due to the lack of material below. At the same time, the diverter plate 21 is lifted to allow the material to fall evenly into each interval separated by the diverter plate 21. Since the material will tilt forward due to inertia when turning over, the block connecting the diverter plate 21 has a certain angle to avoid the phenomenon of the uppermost material tilting forward and falling after turning over. In addition, the hopper 100 for the rod-shaped material can also be provided with a vibration mechanism to vibrate the material evenly through vibration.

[0060] Preferably, in one embodiment, the hopper 100 for rod-shaped materials further comprises a mounting plate 50 and a vibration drive mechanism 60. The vibration drive mechanism 60 is disposed on the mounting plate 50 and connected to the two side plates 14 of the hopper body 10 to drive the two side plates 14 to vibrate. By arranging the vibration drive mechanism 60 to drive the side plates 14 to vibrate, the material can be dropped more evenly to avoid jamming.

[0061] Preferably, in one embodiment, a fixed shaft 51 is provided on the mounting and fixing plate 50. The fixed shaft 51 extends into the hopper body 10, and the shunting mechanism 20 is arranged on the fixed shaft 51 to stably support the shunting mechanism 20.

[0062] Specifically, in one embodiment, the fixed shaft 51 is fixed to the mounting and fixing plate 50 by screws.

[0063] Specifically, in one embodiment, the fixed shaft 51 passes through the back plate 15 and then penetrates into the accommodation cavity 11. A through hole is provided on the mounting block 22 corresponding to the fixed shaft 51. After the fixed shaft 51 penetrates into the through hole, the mounting block 22 is fixed to the fixed shaft 51 by screws.

[0064] More preferably, in one embodiment, the guiding mechanism 30 is also arranged on the fixed shaft 51.

[0065] Preferably, in one embodiment, the vibration driving mechanism 60 includes a vibration driving unit 61, a connecting bracket 62, a vibration bracket 63 and a vibration shaft 64. One side of the connecting bracket 62 is connected to the vibration driving unit 61 through an eccentric shaft 65, and the other side of the connecting bracket 62 is connected to the vibration bracket 63 through a connecting shaft 66. The vibration shaft 64 is arranged on the vibration bracket 63 and is connected to the two side plates 14 of the hopper body 10. When the vibration driving unit 61 operates, the connecting bracket 62 is driven by the eccentric shaft 65 to swing left and right reciprocally, driving the vibration bracket 63 to reciprocate, so as to drive the two side plates 14 to vibrate reciprocally through the vibration shaft 64 on the vibration bracket 63, so as to drive the materials in the accommodation cavity 11 to vibrate reciprocally.

[0066] Specifically, in one embodiment, the vibration driving unit 61 includes a vibration motor 611 and a speed reducer 612. The vibration motor 611 and the speed reducer 612 are fixed together and installed on the mounting and fixing plate 50. After being decelerated by the speed reducer 612, the vibration motor 611 drives the connecting bracket 62 to swing left and right reciprocally through the eccentric shaft 65.

[0067] Specifically, in one embodiment, the connecting bracket 62 is connected to the vibration driving unit 61 through the eccentric shaft 65, a first bearing 651, a first shaft retaining ring 652, a first gasket 653 and screws 654. The connecting bracket 62 is connected to the vibration bracket 63 through the connecting shaft 66, a second bearing, a second shaft retaining ring, a second gasket and a nut.

[0068] Specifically, to prevent the vibration shaft 64 from driving the back plate 15 to vibrate, the aperture of the avoidance hole formed in the back plate 15 is larger than the diameter of the vibration shaft 64, so that the vibration shaft 64 will not contact the back plate 15 during vibration. Further, the side plate 14 can also be spaced apart from the back plate 15 by a certain distance.

[0069] Specifically, in one embodiment, the back plate 15 can be mounted on the mounting fixing plate 50.

[0070] Preferably, in one embodiment, the vibration shaft 64 includes a left vibration shaft 641 and a right vibration shaft 642. The left vibration shaft 641 is connected to the first side plate 141, and the right vibration shaft 642 is connected to the top side plate 1421. Specifically, two left vibration shafts 641 are arranged in the height direction, and the two left vibration shafts 641 are respectively connected to the first side plate 141, thereby improving the stability of vibration. Two right vibration shafts 642 are arranged in the height direction, and the two right vibration shafts 642 are respectively connected to the top side plate 1421, thereby improving the stability of vibration. By driving the vibration bracket 63 to vibrate through one vibration driving unit 61, the two side plates 14 are synchronously driven to vibrate, and the vibration driving of the two side plates 14 is realized in the form of "one driving two", making the overall structure more compact, and the vibration amplitudes are synchronous, so that the blanking on the left and right sides can be more uniform.

[0071] Preferably, in one embodiment, the other side of the connecting bracket 62 is connected to the middle area of the vibration bracket 63 through the connecting shaft 66, so that the force on the vibration bracket 63 is more balanced, and the vibration bracket 63 will not be side-deflected during vibration, improving the stability of synchronously driving the two side plates 14.

[0072] Preferably, in one embodiment, the vibration bracket 63 is mounted on the mounting fixing plate 50 through a spring piece 67. By installing the vibration bracket 63 through the spring piece 67, on the one hand, the vibration bracket 63 can be stably supported, and on the other hand, when the vibration bracket 63 vibrates, the spring piece 67 can also generate a certain deformation and will not hinder the vibration of the vibration bracket 63.

[0073] Specifically, in one embodiment, spring pieces 67 are respectively connected to both sides of the vibration bracket 63, and the two spring pieces 67 suspend and hoist the vibration bracket 63.

[0074] Specifically, in one embodiment, the mounting fixing plate 50 includes a first fixing plate 52 and a second fixing plate 53. The first fixing plate 52 is fixed to the second fixing plate 53 by screws and a connecting plate 54. The spring piece 67 is mounted on the first fixing plate 52 through a connecting block 68. The connecting block 68 and the first fixing plate 52 are fixed by screws. The fixed shaft 51 is fixed to the first fixing plate 52 by screws. The vibration driving unit 61 is mounted on the first fixing plate 53.

[0075] Preferably, in one embodiment, a vibration roller 69 is further provided on the vibration bracket 63. After passing through the back plate 15, the vibration roller 69 extends between two adjacent shunting mechanisms 20. When the vibration bracket 63 vibrates, the vibration roller 69 can be driven to vibrate, so as to disturb the materials in the material falling space between the two shunting mechanisms 20, making the material falling more uniform.

[0076] Preferably, in one embodiment, a conveying mechanism 70 is provided at the bottom of the accommodating cavity 11. The conveying direction of the conveying mechanism 70 faces the discharge port 13, so as to better guide the lower accommodating cavity 112 to move towards the discharge port 13. Specifically, in one embodiment, the conveying mechanism 70 adopts a conveyor belt.

[0077] Specifically, a material taking cutting wheel 200 is provided at the discharge port 13. A material pushing roller 300 is provided at the top of the material taking cutting wheel 200. The material taking cutting wheel 200 is used to pick up materials from the discharge port 13. The material pushing roller 300 is used to push down materials, so that only one material is adsorbed on a single wheel groove of the material taking cutting wheel 200, realizing the orderly conveying of materials. The driving motor of the conveying mechanism 70 and the driving motor of the material pushing roller 300 can be mounted on the mounting fixing plate 50.

[0078] It can be understood that in the field of heated tobacco products, due to the diversity of the materials of the base rod materials and the inconsistency of the weights, more specific requirements are put forward for the diversion and stacking of the materials. At the same time, when receiving the upper material tray, it is necessary to avoid excessive pressure during the material transfer and achieve a smooth transition. In the hopper 100 of the rod-shaped material of the present application, an eccentric mechanism driven by a motor is adopted to realize the vibration of the hopper, and a ramp shunting plate is directly driven by a cylinder to receive the upper materials, and different force adjustments for different materials can be realized. The angle of the ramp can also be adjusted according to the actual situation to meet the specific requirements of different specifications of materials.

[0079] The diverter mechanism 20 added to the hopper 100 for rod-shaped materials of the present application and the up and down lifting of the diverter mechanism 20 play a very important role in the upstream docking of materials. The inclined design of the diverter plate 21 are important designs to ensure that the materials will not easily tip over when docking.

[0080] When the hopper 100 for rod-shaped materials is in operation, when the material level detector 40 alarms to prompt that loading is required, the full tray of materials is transported to the designated position by a specific device, and the materials are poured into the hopper 100 for rod-shaped materials, and smoothly flow into the interior of the hopper 100 for rod-shaped materials under the action of the diverter plate 21. The diverter plate 21 plays a receiving and diverting role. When the full tray of materials turns over, the diverter plate 21 rises under the action of the cylinder to receive the materials above to form several long channel areas. The materials smoothly flow into the accommodating cavity 11 from the middle of two adjacent diverter plates 21. Under the drainage action of the diverter plate 21 and the guide plate of the guide mechanism 30, the materials circulate in the interior of the hopper 100 for rod-shaped materials along the running direction of the material taking and cutting wheel 200 and the horizontal conveyor belt direction of the conveying mechanism 70.

[0081] The entire hopper 100 for rod-shaped materials is mainly composed of a vibration module and a diversion module, and the diversion module is composed of three middle diversion mechanisms 202, the side diversion mechanisms 201 on the left and right sides, and the corresponding guide mechanism 30 and the guide plate installed on the guide mechanism 30, which divides the space in the hopper 100 for rod-shaped materials into several channel areas to ensure the uniform falling of materials. The guide plate can be adjusted within a certain range to control the falling speed of the corresponding area.

[0082] The vibration module is mainly composed of a motor, an eccentric shaft, a spring sheet, a vibration bracket and a shaft installed on the vibration bracket. When feeding at different speeds and different materials, different vibration frequencies can be adopted to meet the needs of the materials.

[0083] Specifically, the conveying belt of the conveying mechanism 70 is driven by a motor pulley, and the speed is adjustable, which can be adjusted according to factors such as the material dropping speed.

[0084] The hopper 100 for rod-shaped materials solves the problem of material tilting forward when the material is turned over and discharged, solves the problem of material disorder at the moment of material discharge, and the adjustable vibration frequency realizes uniform discharge of materials of different weight indicators, which better solves the discharge problem of heated cigarettes.

[0085] The above description is only an implementation mode of the present invention. It should be pointed out that, for ordinary technicians in this field, improvements can be made without departing from the creative concept of the present invention, but these all belong to the protection scope of the present invention.
