Description

Technical Field

[0001] This utility model relates to the field of cigarette production technology, and in particular to a conveying device. Background Technology

[0002] In cigarette manufacturing workshops, feed hoppers are commonly used devices to stabilize flow rates and buffer flow rates between upstream and downstream processes. They are often combined with limiting tubes and electronic belt scales to form a quantitative feeding system for controlling the stability of material flow. Material is first fed into the feed hopper via a conveyor belt. Once the feed hopper is full, the material inside is then conveyed outwards. A level sensor is installed at the top of the feed hopper. When the material in the feed hopper reaches a set height, the level sensor detects that the feed hopper is full, and the conveyor belt stops feeding material into the feed hopper.

[0003] Currently, because the material on the conveyor belt is usually concentrated in the middle (i.e., the material is usually concentrated in the middle of the conveyor belt, resulting in a high material height in the middle and a gradual decrease in material height towards the sides), the material distribution in the feed hopper is also concentrated in the middle. When the material height in the middle of the feed hopper reaches the detection area of ​​the level sensor, the system will misjudge and think that the feed hopper is full, and then the conveyor belt will stop conveying material into the feed hopper. In reality, the areas on both sides of the feed hopper are not yet full, so the actual total amount of material in the feed hopper is less than the preset amount, which easily leads to problems of insufficient or interrupted material delivery when the feed hopper delivers material outwards. Utility Model Content

[0004] The purpose of this invention is to solve the technical problem that current systems are prone to misjudgment, resulting in insufficient material in the feeding hopper and causing material shortages or interruptions when the feeding hopper delivers material. This invention provides a conveying device that can avoid system misjudgment, ensuring that the amount of material in the feeding hopper meets the requirements and preventing material shortages or interruptions.

[0005] An embodiment of this utility model provides a conveying device, comprising:

[0006] A conveyor belt extends in a first direction and is used to transport materials. The two ends of the conveyor belt along its running direction are the feed end and the discharge end, respectively.

[0007] The material leveling plate is located above the conveyor belt. The material leveling plate has a mounting surface on the side facing the conveyor belt, and an insert is provided on the mounting surface. The insert can at least partially extend into the material. When the material passes through the insert, the material can be diverted to both sides of the insert along the width direction of the conveyor belt.

[0008] According to another specific embodiment of the present invention, the material leveling plate is disposed near the discharge end, and the insert includes a first diverter plate and a second diverter plate. The upper surfaces of the first diverter plate and the second diverter plate are in contact with the mounting surface. The end of the first diverter plate near the feed end is the first fixed end, and the end of the second diverter plate near the feed end is the second fixed end. The first fixed end and the second fixed end are connected, and the distance between the first diverter plate and the second diverter plate gradually increases along the material conveying direction.

[0009] According to another specific embodiment of the present invention, a fixed shaft is provided on the mounting surface, the fixed shaft is perpendicular to the upper surface of the conveyor belt, and the first fixed end and the second fixed end are rotatably connected to the fixed shaft.

[0010] According to another specific embodiment of the present invention, a sliding groove is also provided on the mounting surface. The sliding groove penetrates the mounting surface in a vertical direction. The sliding groove is arc-shaped and has two sliding members inside. The two sliding members can slide inside the sliding groove. The end of the first diverter plate near the discharge end is the first moving end, and the end of the second diverter plate near the discharge end is the second moving end. The first moving end and the second moving end are respectively hinged to the two sliding members.

[0011] According to another specific embodiment of the present invention, the sliding member is further provided with a locking member, which is used to lock the sliding member to limit the position of the sliding member in the groove.

[0012] According to another specific embodiment of this utility model, the locking element is a bolt.

[0013] According to another specific embodiment of this utility model, the number of inserts is at least two.

[0014] According to another specific embodiment of the present invention, the number of inserts is three, namely a first insert, a second insert, and a third insert, which are arranged in a triangular pattern.

[0015] The first insert is located near the feed end and is positioned at the center line of the conveyor belt, with the center line extending along the first direction.

[0016] The second and third inserts are positioned close to the discharge end, and are symmetrically positioned on both sides of the dividing line.

[0017] According to another specific embodiment of the present invention, the number of slides is the same as the number of inserts, and the position of each slide corresponds one-to-one with the position of each insert.

[0018] According to another specific embodiment of the present invention, the conveyor belt is provided with a side wall on both sides along its width direction, and the material leveling plate is provided with two connecting plates on both sides along the width direction of the conveyor belt. The two connecting plates are slidably connected to the two side walls respectively. The connecting plates can move vertically between a first position and a second position. When the connecting plate is in the first position, the bottom of the insert is in contact with the upper surface of the conveyor belt; when the connecting plate is in the second position, there is a gap between the bottom of the insert and the upper surface of the conveyor belt.

[0019] Compared with the prior art, this utility model has the following beneficial effects:

[0020] The conveying device provided by this utility model includes a conveyor belt and a leveling plate, with an insert on the side of the leveling plate facing the conveyor belt. When the material on the conveyor belt runs to the bottom of the leveling plate, the insert extends into the material. As the conveyor belt runs, the material is diverted along the width of the conveyor belt to both sides of the insert due to the obstruction of the insert, thereby dispersing the relatively concentrated material and avoiding uneven material distribution. This prevents material shortages and interruptions caused by uneven material distribution in the feeding box. Attached Figure Description

On the contrary, the purpose of describing the utility model in conjunction with the embodiments is to cover other options or modifications that may be derived based on the claims of this utility model. To provide a deep understanding of this utility model, many specific details will be included in the following description. This utility model may also be implemented without using these details.

[0030] In the description of this embodiment, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment based on the specific circumstances.

[0031] Currently, because the material on the conveyor belt is usually concentrated in the middle, the material in the feed hopper is also concentrated in the middle, leading to potential system misjudgments. When the material height in the middle of the feed hopper reaches the detection area of ​​the level sensor, the system misjudges that the feed hopper is full and the conveyor belt stops feeding material into the feed hopper. In reality, the areas on both sides of the feed hopper are not yet full, so the actual total amount of material in the feed hopper is less than the preset amount, causing problems such as material shortages and interruptions when the feed hopper feeds material out.

[0032] To solve the above-mentioned technical problems, this utility model provides a conveying device that enables materials to be fed into the feeding box in a dispersed manner, avoiding the concentration of materials in the feeding box, thereby avoiding system misjudgment, ensuring that the amount of material filled in the feeding box meets the requirements, and thus avoiding the problems of material shortage or interruption.

[0033] To make the technical solution and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below.

[0034] refer to Figure 1 The present invention provides a conveying device, including a conveyor belt 1 and a leveling plate 2, wherein the conveyor belt 1 is along a first direction (e.g., Figure 1 Extending in the X direction (as shown in the figure), the conveyor belt 1 is used to convey materials, and the conveyor belt 1 extends along its running direction (as shown in the figure). Figure 1 The two ends of the conveyor belt 1 (as shown in the M direction) are the feed end 11 and the discharge end 12, respectively. The leveling plate 2 is located above the conveyor belt 1, near the discharge end 12. The leveling plate 2 has a mounting surface 21 on the side facing the conveyor belt 1, and an insert 3 is provided on the mounting surface 21. The insert 3 can at least partially extend into the material. When the material passes the insert 3, the material can be moved along the width direction of the conveyor belt 1 (e.g., ...). Figure 1 (As shown in the Z direction) the flow is diverted to both sides of the insert 3.

[0035] Optionally, the number of inserts 3 is at least two. For example, refer to... Figure 2 and Figure 3 There are three inserts 3: a first insert 10, a second insert 13, and a third insert 14, arranged in a triangular pattern. The first insert 10 is positioned near the feed end 11 and is located at the center line of the conveyor belt 1 (e.g., ...). Figure 1 As shown by the dashed line L in the diagram, the center line L extends along the first direction, and the distance between the center line L and the two edges of the conveyor belt 1 extending along the first direction is equal. The second insert 13 and the third insert 14 are disposed near the discharge end 12, and the second insert 13 and the third insert 14 are symmetrically disposed on both sides of the center line L.

[0036] Specifically, refer to Figure 3 Each insert 3 includes a first diverter plate 4 and a second diverter plate 5. The upper surfaces of both the first diverter plate 4 and the second diverter plate 5 are connected to the mounting surface 21. The end of the first diverter plate 4 near the feed end 11 is the first fixed end 41, and the end of the second diverter plate 5 near the feed end 11 is the second fixed end 51. The first fixed end 41 and the second fixed end 51 are connected, and the distance between the first diverter plate 4 and the second diverter plate 5 gradually increases along the material conveying direction. When the material runs to the bottom of the equalizing plate 2 and comes into contact with the first diverter plate 4 and the second diverter plate 5, with the operation of the conveyor belt 1, the material will gradually move towards both sides of the conveyor belt 1 under the action of the first diverter plate 4 and the second diverter plate 5, thereby dispersing the relatively concentrated material to avoid uneven material distribution and thus avoid the problem of material shortage or interruption caused by uneven material distribution in the feeding box.

[0037] by Figure 2 Taking the illustrated technical solution as an example, when the material runs to the area below the equalizing plate 2, the material first passes through the first insert 10. Upon passing through the first insert 10, the material concentrated near the dividing line L of the conveyor belt 1 is diverted to both sides of the first insert 10. Subsequently, when the material passes through the second insert 13 and the third insert 14, the material located on both sides of the first insert 10 will be diverted again by the second insert 13 and the third insert 14. This application, by setting three inserts 3, facilitates the comprehensive diversion of material on the conveyor belt 1, thereby achieving a uniform distribution of material along the width direction of the conveyor belt 1.

[0038] Optionally, refer to Figure 3 A fixed shaft 6 is provided on the mounting surface 21. The number of fixed shafts 6 is the same as the number of inserts 3, and the positions of each fixed shaft 6 and each insert 3 correspond one-to-one. The fixed shaft 6 is perpendicular to the upper surface of the conveyor belt 1, and the first fixed end 41 and the second fixed end 51 on each insert 3 are rotatably connected to the corresponding fixed shaft 6. Further, refer to... Figure 2 and Figure 3 The mounting surface 21 is also provided with sliding grooves 7. The number of sliding grooves 7 is the same as the number of inserts 3, and the position of each sliding groove 7 corresponds one-to-one with that of each insert 3. The sliding grooves 7 are along the vertical direction (e.g., Figure 3 (As shown in the Y direction) penetrating the mounting surface 21, the slide groove 7 is arc-shaped, and each slide groove 7 is provided with two sliding members 8, which can slide within the slide groove 7. The end of the first diverter plate 4 near the discharge end 12 is the first moving end 42, and the end of the second diverter plate 5 near the discharge end 12 is the second moving end 52. The first moving end 42 and the second moving end 52 on each insert 3 are respectively hinged to the two sliding members 8 on the corresponding slide groove 7. When the two sliding members 8 slide within the slide groove 7, they can respectively drive the first fixed end 41 and the second fixed end 51 to rotate around the corresponding fixed axis 6, thereby changing the included angle between the first diverter plate 4 and the second diverter plate 5 on each insert 3.

[0039] This application, by setting a chute 7 and a sliding member 8, allows the first fixed end 41 and the second fixed end 51 on each insert 3 to rotate around their corresponding fixed axes, thereby adjusting the included angle between the first diverter plate 4 and the second diverter plate 5 on each insert 3. In actual production, the included angle between the first diverter plate 4 and the second diverter plate 5 can be adjusted according to the concentration of material on the conveyor belt 1. If the concentration of material is high, the first diverter plate 4 and the second diverter plate 5 are rotated to increase the included angle, thereby allowing more material to be diverted to both sides of the conveyor belt 1 for uniform material distribution. If the concentration of material is low, the first diverter plate 4 and the second diverter plate 5 are rotated to decrease the included angle, thus preventing excessive material from being dispersed to both sides of the conveyor belt 1, resulting in a higher material height on both sides. This application can adjust the unfolding degree of the first diverter plate 4 and the second diverter plate 5 according to actual needs to properly divert the material, so that the material on the conveyor belt 1 is evenly distributed, thereby avoiding the problem of material shortage or interruption caused by uneven material distribution in the feed box.

[0040] Optionally, refer to Figure 4 The sliding member 8 is also provided with a locking member 9, which is used to lock the sliding member 8 to limit its position within the groove 7. Exemplarily, the upper surface of the sliding member 8 is lower than the upper surface of the uniform material plate 2. The sliding member 8 has a threaded hole, and the locking member 9 can be a bolt, which includes a head and a screw. The head is located above the uniform material plate 2, and the screw passes through the groove 7 and is threaded into the threaded hole. A shim is provided between the head and the upper surface of the uniform material plate 2, and the diameter of the shim is larger than the width of the groove 7. After adjusting the positions of the first diverter plate 4 and the second diverter plate 5, tightening the bolt applies pressure to the shim towards the uniform material plate 2, pressing the shim against the upper surface of the uniform material plate 2 to lock the sliding member 8, thereby preventing accidental movement of the sliding member 8.

[0041] Optionally, refer to Figure 1 and Figure 3 The conveyor belt 1 has a sidewall 15 on each side along its width direction, and the equalizing plate 2 has two connecting plates 16 on each side along its width direction. The two connecting plates 16 are slidably connected to the two sidewalls 15. Specifically, each sidewall 15 has a vertically extending slide rail (not shown in the figure) on the side away from the conveyor belt 1. Each connecting plate 16 has a slider (not shown in the figure) on the side facing the corresponding sidewall 15. The slider is mounted on the corresponding slide rail and can slide along the slide rail, allowing the connecting plate 16 to move vertically between a first position and a second position. When the connecting plate 16 is in the first position, the bottom of the insert 3 is in contact with the upper surface of the conveyor belt 1. When the connecting plate 16 is in the second position, there is a gap between the bottom of the insert 3 and the upper surface of the conveyor belt 1.

[0042] Specifically, the slider is provided with a threaded hole, and a bolt is threaded into the threaded hole. After adjusting the position of the connecting plate 16, tighten the bolt so that the nut on the bolt presses against the side wall 15 to lock the slider. By setting the connecting plate 16, this application facilitates the adjustment of the distance between the insert 3 and the conveyor belt 1, thereby allowing the insertion depth of the insert 3 into the material to be adjusted according to the height of the concentrated accumulation of material, so as to divert an appropriate amount of material and make the material distribution on the conveyor belt 1 uniform, thus avoiding the problems of material shortage or interruption caused by uneven material distribution in the feeding box.

Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
