Description

Technical Field

[0001] The utility model relates to the technical field of tobacco shredded warehouse type feeders, in particular to a metering tube of a tobacco shredded warehouse type feeder which is convenient for adjusting the metering width. Background Art

[0002] Silo feeders are essential equipment in tobacco production workshops, primarily used for conveying tobacco over short horizontal distances and at high heights. Upstream equipment delivers material into the silo, where it is evenly distributed and fed to downstream equipment via inclined conveyor belts, ensuring a continuous, uniform, and stable material supply throughout the production process.

[0003] A silo feeder primarily consists of a silo, a material distribution cart, an elevator section, a metering tube, a motor, and related detection components. According to smoke exhaust fan design specifications, the size of the metering tube for a silo feeder must be designed and manufactured based on factors such as the process design material flow rate and the dimensions of the downstream equipment's material distribution area. However, in actual use, it has been found that when the process design material flow rate changes, especially when the design material flow rate increases, it is necessary to redesign and manufacture a new metering tube and modify the silo feeder's discharge hopper to adapt it. Even when the process design material flow rate fluctuates significantly, it is necessary to re-purchase a silo feeder that meets the requirements, which in turn increases modification and investment costs.

[0004] Although the prior art discloses a metering tube that can adjust the metering width by synchronously adjusting the swing valve and the sliding door through a motor, the adjustment of the valve and the sliding door must be synchronized to achieve the adjustment of the width of the metering tube. In actual tobacco shred feeding metering, it is necessary to set a matching metering tube volume according to the material flow setting value of the electronic scale. Increasing the width of the metering tube increases the volume, and raising the height of the sliding door reduces the metering tube volume and increases the flow rate. It can be seen that adjusting the height of the sliding door is not conducive to controlling the metering tube volume to match the setting value. There is a problem that a single adjustment factor cannot be determined, resulting in the metering tube width being difficult to adjust to match the electronic scale material flow setting value or the metering width of the metering tube being inconvenient to adjust. Utility Model Content

[0005] The purpose of the utility model is to address the problems in the prior art that the metering width of the metering tube is inconvenient to adjust or difficult to match the logistics flow setting value of the electronic scale, and to provide a metering tube for a tobacco silk silo feeder that is easy to adjust the metering width, comprising a silo and an adjustable baffle plate, the upper end of the adjustable baffle plate being hinged to the fixed baffle plate of the silo, so that the adjustable baffle plate can swing around the fixed baffle plate and thus open to different angles with the fixed baffle plate of the silo; the two sides adjacent to the silo and the fixed baffle plate are side baffles, a guide plate is provided between the side baffle and the adjustable baffle plate, the guide plate is provided with a guide groove guiding along the swinging direction of the adjustable baffle plate, and the adjustable baffle plate is relatively slidably connected to the side baffle through the guide groove; the guide plate is provided with a locking member for locking the position of the adjustable baffle plate.

[0006] The metering tube of the tobacco shredder type feeder of the utility model is easy to adjust the metering width, and the upper end of the adjustable baffle plate is hinged to the fixed baffle plate of the hopper, so that the adjustable baffle plate can swing around the fixed baffle plate of the hopper and thus open to different angles with the fixed baffle plate of the hopper, so that the opening of the baffle plate can be adjusted, thereby adjusting the metering width of the metering tube, and by providing a guide plate and a guide groove guided along the swinging direction of the adjustable baffle plate, the guide plate is fixed to the hopper, so that the adjustable baffle plate can swing and open to a certain angle when the adjustable baffle plate is swung, so that the metering width of the metering tube matches the set value of the logistics flow of the electronic scale. The cam is adapted to move the cam in a direction that allows the cam to move freely in the desired direction and to adjust the width of the cam so that the cam can move freely in the desired direction.

[0007] Preferably, in the metering tube of the tobacco shredder feeder with easy adjustment of metering width described in the present invention, the guide groove is an arc-shaped guide groove that is concentric with the swing circle of the adjustable baffle plate.

[0008] As a preferred solution of the present invention, by making the guide groove an arc-shaped guide groove that is concentric with the swing of the adjustable material baffle plate, the adjustable material baffle plate can be synchronously guided and supported in an arc-shaped manner that is concentric with the swing direction, so that the adjustable material baffle plate can be smoother in the process of adjusting the swing angle, and the adjustable material baffle plate can be adjusted conveniently, quickly and accurately.

[0009] Preferably, in the metering tube of the tobacco shredder feeder with easy adjustment of metering width described in the present invention, the maximum opening angle of the adjustable baffle is forty degrees, and the curvature of the guide groove matches the opening angle.

[0010] As a preferred solution of the present invention, after actual measurement experience testing, when the opening angle of the adjustable baffle exceeds 40 degrees, when the material falls from the top of the metering tube, the material will be sprayed onto the electronic scale belt below the metering tube in a large area, which will in turn make the material compacted insufficiently, resulting in too low a material density on the electronic scale, and causing the material process flow to be inaccurate. This preferred solution designs the opening angle of the adjustable baffle to be a maximum of 40 degrees in the angle system, and the curvature of the guide groove matches the opening angle. The metering tube can meet a larger metering width, and within this opening angle, the material will not be sprayed onto the electronic scale belt below the metering tube in a large area, reducing the probability of insufficient material compaction, reducing the impact of the present invention on product quality, and improving production quality.

[0011] Preferably, the metering tube of the tobacco shredder feeder with easy adjustment of metering width described in the present invention is provided with at least two sets of sensors located at the upper and lower parts of the silo respectively on the inner side of the silo, and the sensors are used to detect the height of the material in the silo.

[0012] As a preferred solution of the present invention, by arranging at least two groups of sensors located at the upper and lower parts of the inner side of the silo respectively, the height of the material in the silo can be detected, and the actual height of the material in the silo can be detected by the sensors. When the material in the silo is piled high and affects the falling of the material, resulting in material jamming, the feed amount of the feed port can be adjusted in time to reduce the probability of production suspension due to material jamming, thereby improving production efficiency.

[0013] Preferably, the metering tube of the tobacco shredder feeder with easy adjustment of metering width described in the present invention comprises a middle material level detection sensor, and the middle material level detection sensor is located at a height of the silo that is 0-5 cm lower than the hinge between the adjustable baffle plate and the silo.

[0014] As a preferred solution of the present invention, a middle material level detection sensor is formed by setting the sensor to be 0-5 cm lower than the hinge between the adjustable material baffle and the silo. Since there are hinged parts and gaps at the hinge of the adjustable material baffle and the silo to which it belongs, there will be a risk of material jamming when the material height is higher than this hinge. When the middle material level detection sensor detects that the material has reached the hinge close to 5 cm or less than 5 cm, the sensor signal transmission can be fed back to the material control end to stop feeding, thereby avoiding the risk of material jamming at the hinge, reducing the failure rate of the use of the present invention, and further improving production efficiency.

[0015] Preferably, the sensor comprises a low material level detection sensor, and the low material level detection sensor is located at a height of the silo that is 0-10 cm lower than the bottom end of the adjustable baffle.

[0016] As a preferred solution of the present invention, a mid-level detection sensor is arranged at 0-10 cm lower than the bottom end of the adjustable material baffle. Since the electronic scale belt is below the bottom end of the adjustable material baffle, the electronic scale belt is turned on when the metering tube starts to feed the material but does not reach the electronic scale belt, which will result in less material on the electronic scale because the material does not completely fall onto the electronic scale. By arranging a low-level detection sensor at 0-10 cm below the bottom end of the adjustable material baffle, the electronic scale belt is turned on only after the low-level sensor detects that the material has accumulated on the electronic scale. This can avoid the unevenness of the material caused by the delay in mechanical operation, thereby further improving the uniformity of the material flow, and improving the measurement accuracy of the present invention and the production quality.

[0017] Preferably, the metering tube of the tobacco shredder feeder with easy adjustment of metering width described in the present invention is provided with a compacting wheel assembly at the bottom end of the adjustable baffle plate, and the compacting wheel assembly can compact the material at the outlet of the silo.

[0018] In this preferred solution, a compacting wheel assembly is arranged at the bottom end of the adjustable material baffle plate. After the opening angle of the adjustable material baffle plate is fixed, the compacting wheel assembly can compact the material at the outlet of the silo on the electronic scale, so that the material is shaped, thereby making the density of the material on the electronic scale uniform and the shape regular, thereby improving the accuracy of the material process flow on the electronic scale.

[0019] Preferably, the metering tube of the tobacco shredder feeder with easy adjustment of metering width described in the present invention, the compacting wheel assembly includes: a roller with both ends fixed to the adjustable baffle plate, and a roller rollingly connected to the roller.

[0020] In this preferred solution, based on the setting of a compacting wheel assembly, the compacting wheel assembly is set as a roller and a roller connected to the roller. The roller can compact the material while rolling around the roller, and can also compact and shape the material into a rectangle according to the length of the roller, thereby further enhancing the uniformity of the material density of the electronic scale and further improving the accuracy of the material process flow on the electronic scale.

[0021] Preferably, the metering tube of the tobacco shredder feeder with easy adjustment of metering width described in the present invention is provided with vertically arranged eyelet strip holes, and the compacting wheel assembly is detachably fixed to the eyelet strip holes.

[0022] In this preferred embodiment, the vertical arrangement of the eyelet holes provides connection holes of different heights. The compacting wheel assembly can be detachably fixed to the connection holes of different heights, so that the compacting wheel assembly can be adjusted in height according to the need to compact the material. This can prevent the roller of the compacting wheel assembly from being adjusted too high and unable to compact the material, and can also prevent the compacting wheel assembly from being too low and causing the material to get stuck, thereby achieving a height that can compact the material and further improving the uniformity of the material density.

[0023] Preferably, in the metering tube of the tobacco shredder feeder with easy adjustment of metering width described in the present invention, the side baffle is a transparent window.

[0024] In this preferred solution, the side baffle is set as a transparent window, which can be used as an observation window on the outside to observe the status of material passing through, thereby improving the monitorability of the metering tube described in the utility model. Through monitoring through the observation window, the feed or discharge can be adjusted in real time according to the status of material passing through, further reducing the equipment failure rate and further improving production efficiency.

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0026] The utility model can realize the independent adjustment of the metering width of the metering tube on the basis of the adjustable opening of the material baffle plate, and can quickly match the metering width of the metering tube with the set value of the electronic scale logistics flow, so that each continuous opening corresponds to each metering width one by one, thereby improving the accuracy of the metering width adjustment of the metering tube, and quickly completing the control of the adjustable material baffle plate relative to the silo opening, with small error, simple operation and high efficiency, so as to realize faster, more convenient and stable adjustment of the metering tube width to match the material flow value of the electronic scale, thereby improving the continuity and uniformity of material supply and the stability of process material flow.

DETAILED DESCRIPTION

[0031] The present invention will be described in detail below with reference to the accompanying drawings.

[0032] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0033] Example 1

[0034] like Figure 1 As shown, the metering tube of the tobacco shredder feeder with easy adjustment of the metering width described in the utility model comprises: a silo 1 and an adjustable baffle plate 2, the upper end of the adjustable baffle plate 2 is hinged to the fixed baffle plate 11 of the silo 1 by a hinge 12, so that the adjustable baffle plate 2 can swing around the fixed baffle plate 11 of the silo 1 and thus open to different angles with the fixed baffle plate 11 of the silo 1; the two sides adjacent to the silo 1 and the fixed baffle plate 11 are side baffles 13, and a guide plate 3 is provided between the side baffle 13 and the adjustable baffle plate 2, and the guide plate 3 is provided with a guide groove 4 guiding along the swinging direction of the adjustable baffle plate 2, and the adjustable baffle plate 2 is connected to the side baffle 13 in relative sliding manner through the guide groove 4; the guide plate 3 is provided with a locking member 5 for locking the position of the adjustable baffle plate 2.

[0035] In this embodiment, the silo 1 of the metering tube is placed vertically. The silo 1 includes side baffles 13 arranged on both sides of the adjustable baffle plate 2 and a back plate 14 arranged opposite to the adjustable baffle plate 2. The back plate 14 is fixedly and sealedly connected to the side baffles 13 and the fixed baffle plate 11. The side baffles 13 are preferably transparent baffles made of organic glass, which can be used as observation windows for observing the state of material passing through. The back plate 14 is preferably made of stainless steel, which can enhance the sturdiness of the metering tube silo 1. The upper end of the adjustable baffle plate 2 is hinged to the fixed baffle plate 11 opposite to the back plate 14 through a hinge 12, so that the two side edges of the adjustable baffle plate 2 are respectively located on the vertical surfaces of the baffles 13 on both sides.

[0036] like Figure 1 and Figure 2As shown, it should be noted that the adjustable baffle plate 2 and the fixed baffle plate 11 are opened at different angles. It can be understood that the fixed baffle plate 11 is the upper half of one side wall of the silo 1, and the adjustable baffle plate 2 is the lower half on the same side as the fixed baffle plate 11. Since the adjustable baffle plate 2 is hinged to the fixed baffle plate 11 by a hinge 12, the adjustable baffle plate 2 here can not only open but also close when swung. That is, when closed, the opening angle with the fixed baffle plate 11 is zero degrees, thereby realizing the opening and closing swing of the adjustable baffle plate 2.

[0037] In this embodiment, a guide plate 3 is provided between the side baffle 13 and the two sides of the adjustable baffle plate 2. It should be noted that, if Figure 1 As shown, the guide plate 3 can be fixed on the adjustable baffle plate 2, and a connecting piece that can slide relatively in the guide groove 4 is provided on the side baffle 13, such as a locking nut of the locking piece 5. The locking nut is not locked on the guide plate 3 but passes through the guide groove 4 and can slide relatively in the guide groove 4. It can also be understood that the guide plate 3 and the guide groove 4 slide relative to the locking nut. By tightening the locking nut on the guide plate 3, the guide plate 3 and the guide groove 4 are locked and will not slide. After adjusting the opening angle of the adjustable baffle plate 2, the position of the adjustable baffle plate 2 is locked to achieve locking of the position of the adjustable baffle plate 2.

[0038] In this embodiment, a guide plate 3 is arranged between the side baffle 13 and the two sides of the adjustable material baffle 2. It can also be understood that the guide plate 3 is fixed to the inner side of the side baffle 13 of the silo 1, and a locking member 5 is fixedly arranged on the side of the adjustable material baffle 2. The locking member 5 can be set as a locking nut, and the locking nut is slidably connected to the guide groove 4. When the locking nut is not locked to the guide plate 3, the screw part of the locking nut slides relatively in the guide groove 4, and the guide plate 3 and the guide groove 4 are fixed to the side baffle 13, so that the adjustable material baffle 2 can be guided by the guide plate 3 through the locking nut.

[0039] After adjusting the adjustable baffle plate 2, several nuts are used to fix it on both sides of the metering tube to prevent the adjustable baffle plate 2 from tilting or bulging due to the squeezing of the tobacco material on the baffle plate, which can further prevent the tobacco material from leaking.

[0040] By adjusting the opening size of the blanking port 10, the production requirements of different process design flow rates can be met within a certain range. At the same time, according to the actual application test data, the process design flow rate is also 1180kg / h, and other equipment conditions remain unchanged. Before the application of the utility model, the average CPK of the process flow rate of a single batch of materials was 1.15. CPK refers to the degree to which the process capability meets the technical standard specifications and tolerances. After the application of the utility model, the average CPK of the process flow rate of a single batch of materials reached 13.7, and the stability of the material flow was greatly improved.

[0041] In this embodiment, Figure 1As shown, the guide groove 4 is an arc-shaped guide groove 4 that is concentric with the swing circle of the adjustable baffle plate 2. It should be noted that the upper end of the adjustable baffle plate 2 of the utility model is hinged to the fixed baffle plate 11 of the silo 1 through a hinge 12, so that the adjustable baffle plate 2 can swing around the fixed baffle plate 11 of the silo 1 and thus open at different angles with the fixed baffle plate 11 of the silo 1. The hinge position of the rotation center of the swing of the adjustable baffle plate 2 always swings in a circle with the hinge 12 axis as the rotation axis. It can be seen that by setting the guide groove 4 to an arc with the hinge 12 axis as the center, the arc-shaped guide groove 4 can be concentric with the swing circle of the adjustable baffle plate 2. The baffle plate can also be set as an arc-shaped guide plate 3 that is concentric with the swing circle of the adjustable baffle plate 2, further improving the synchronization of the swing guide of the adjustable baffle plate 2 and further enhancing convenience.

[0042] In this embodiment, the maximum opening angle of the adjustable baffle plate 2 is forty degrees, and the curvature of the guide groove 4 matches the opening angle. The opening and closing angle of the adjustable baffle plate 2 can reach 40 degrees. When the opening angle of the adjustable baffle plate 2 is forty degrees, the metering width in the metering tube is maximized, and the material volume ratio is maximized. When the opening and closing angle exceeds forty degrees, when the material falls from the top of the metering tube, the material will be sprayed onto the electronic scale belt below the metering tube over a large area, which may cause insufficient compaction of the material, resulting in too low a material density on the electronic scale, and causing the material process flow CPK value to be too low.

[0043] The utility model is a metering tube for a tobacco shredding bin-type feeder that is easy to adjust the metering width. Through actual use tests, it has been found that the metering width of the metering tube of the bin-type feeder is expanded and the material volume rate can be increased by up to 30% without replacing the metering tube and the bin-type feeder.

[0044] In this embodiment, at least two groups of sensors 6 can be provided on the inner side of the silo 1, respectively located at the upper and lower parts of the silo 1. The sensors 6 are used to detect the height of the material in the silo 1 and can adjust the feed amount of the feed port in time. The sensors 6 can be installed on the back plate 14 through the fixed support rod 60 to reduce the probability of suspending production due to material jamming, thereby improving production efficiency.

[0045] In this embodiment, the two groups of sensors 6 can be respectively set as a middle material level detection sensor 61 and a low material level detection sensor 62. The middle material level detection sensor 61 is located at a height of the silo 1 that is 0-5 cm lower than the hinge point between the adjustable material baffle 2 and the silo 1, and the low material level detection sensor 62 is located at a height of the silo 1 that is 0-10 cm lower than the bottom end of the adjustable material baffle 2.

[0046] refer to Figure 3 As shown, the sensor 6 includes a group of sensors located at the back plate 14 on the upper part of the silo 1 and adjacent to the baffles 13 on both sides, including two components located on the baffles 13 on both sides, such as Figure 3The material level detection sensor 61 in the middle, the sensor 6 can also include a group of sensors located at the lower part of the silo 1 adjacent to the two side baffles 13, including two components located at the two side baffles 13, such as Figure 3 The low material level detection sensor 62 in the metering tube transmits a detection signal to the control system when the sensor 6 detects the height reached by the material in the metering tube, thereby detecting the height of the material in the metering tube.

[0047] In this embodiment, a compacting wheel assembly 7 is provided at the bottom end of the adjustable material retaining plate 2 , and the compacting wheel assembly 7 can compact the material at the outlet of the silo 1 .

[0048] It should be noted that the bottom end of the adjustable material baffle plate 2 is the electronic scale belt, and the compacting wheel assembly 7 is fixedly connected or detachably fixedly connected to the bottom end of the adjustable material baffle plate 2 through a fixing part. If the position of the adjustable material baffle plate 2 is locked, the position of the compacting wheel assembly 7 can be locked, thereby realizing the compaction processing of the outlet material of the silo 1. The locking part 5 is preferably a locking nut, which is used to lock the position of the adjustable material baffle plate 2 after adjusting the opening angle of the adjustable material baffle plate 2, thereby locking the position of the compacting wheel assembly 7.

[0049] In the present invention, the compacting wheel assembly 7 includes: a roller 71 with both ends fixed to the adjustable material blocking plate 2 , and a roller 72 rollingly connected to the roller 71 .

[0050] In the present invention, the adjustable retaining plate 2 is provided with a vertically arranged eyelet strip, and the compacting wheel assembly 7 is removably secured to the eyelet strip. The eyelet strip is a strip-shaped connector with several connecting holes at different heights. By connecting to holes at different positions on the eyelet strip, the compacting wheel assembly 7 can be secured to different heights of the adjustable retaining plate 2. The height difference between the lowest and highest holes of the eyelet strip can also be designed to be approximately 10 cm, allowing the height of the roller 72 to be adjusted by approximately 10 cm.

[0051] It should be noted that the height of the roller 72 from the electronic scale belt is set according to the actual production process of the material that can be transported on the electronic scale. There is no special restriction as long as there is no jam. That is, by limiting the height difference range between the lowest hole and the highest hole of the eyelet strip, the roller 72 of the compacting wheel assembly 7 is prevented from being adjusted too high and unable to compact the material, and the compacting wheel is prevented from being too low and causing the material to get stuck. The adjustment is carried out to a height that can compact the material and further improve the uniformity of the material density.

[0052] like Figure 3As shown, the upper end of the metering tube of the present invention is fixedly connected to the drop port 10 of the feeder. The drop port 10 is in the shape of a funnel with a large angle at the upper end and a small angle at the lower end. The side wall of the drop port 10 is also provided with a cleaning window 101 for cleaning the drop port 10. The cleaning window 101 is connected to the side wall of the drop port 10 through the opening and closing of the cleaning window assembly 102. Opening the cleaning window 101 can more conveniently clean the inside of the drop port 10. A high material level detection sensor 63 is also provided outside the drop port 10 for detecting the height of the material at the drop port 10, so as to further more accurately and conveniently control the drop amount of the material.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
