Description

Technical Field

[0001] This utility model relates to the field of rod-shaped material conveying equipment, and more specifically, to a stockpile-type rod-shaped material buffer storage device. Background Technology

[0002] When conveying rod-shaped materials such as cigarettes, it is necessary to match the conveying capacity of the upstream equipment with the receiving capacity of the downstream equipment to avoid phenomena such as compression or breakage. Therefore, it is necessary to install a buffer device on the conveying channel connecting the upstream and downstream equipment to buffer the rod-shaped materials. The buffer device can buffer when the conveying speed of the upstream equipment is too fast, and replenish the rod-shaped materials in time when the receiving speed of the downstream equipment is too fast.

[0003] For example, patent application CN119117714A discloses a layered material buffering device and storage method. The material buffering device includes a storage cabinet, inside which are arranged multiple buffer belt conveyors spaced vertically. A guide channel is provided between two adjacent buffer belt conveyors. The upper end of the guide channel is connected to the discharge end of the buffer belt conveyor above it, and the lower end of the guide channel is connected to the feed end of the buffer belt conveyor below it. The storage method specifically includes: the buffer belt conveyor at the top layer receiving material from the feeding belt conveyor; the first-layer buffer belt conveyor starting operation; after the first-layer buffer belt conveyor is full of material, it conveys the material to the second-layer buffer belt conveyor; the second-layer buffer belt conveyor starting operation to convey the material; after the second-layer buffer belt conveyor is full of material, it continues to convey the material to the buffer belt conveyors below it, until the material is conveyed to the bottom buffer belt conveyor. This material buffering device and storage method allows materials to fall in layers, achieving flexible buffering and preventing material collisions and compression, effectively avoiding material breakage and damage. However, the disclosed structure of this layered storage material buffering device is relatively complex, and it cannot discharge the buffered material in a timely manner. Utility Model Content

[0004] In order to simplify the structure of the rod-shaped material buffer storage device and improve the discharge efficiency of the buffered material, the technical solution adopted by this utility model is: a stockpile-type rod-shaped material buffer storage device, installed on the conveying channel, including a flexible belt, a left winding shaft, a right winding shaft, and a detection device;

[0005] The flexible belt is connected between the left winding shaft and the right winding shaft and is located on the lower side of the conveying channel, and is used to adjust the amount of buffer rod material by changing its own winding length;

[0006] The detection device is located on the upper side of the conveying channel and above the flexible belt. It is used to sense the amount of rod-shaped material buffered on the flexible belt and to change the winding length of the flexible belt by controlling the rotation direction of the left winding shaft and the right winding shaft.

[0007] Based on the above, in order to sense the amount of buffered material in a timely manner, the detection device includes a controller, a detection container with an open bottom, and a flap that is rotatably installed in the detection container for the rod-shaped material to be lifted up. The detection container is also equipped with a rotation displacement sensor for sensing the position of the flap, and the rotation displacement sensor is signal-connected to the controller.

[0008] The controller is used to change the rotation direction of the left winding shaft and the right winding shaft according to the position of the flip plate sensed by the rotation displacement sensor.

[0009] Based on the above, in order to facilitate tensioning or pushing the flexible belt, a left push wheel is provided on one side of the left winding shaft, and a right push wheel is provided on one side of the right winding shaft. The left push wheel and the right push wheel are used to support the flexible belt.

[0010] Based on the above, a left pressure roller is provided between the left winding shaft and the left push roller, and a right pressure roller is provided between the right winding shaft and the right push roller. The left pressure roller and the right pressure roller are used to tension the two ends of the flexible belt.

[0011] Based on the above, one end of the flexible belt is connected to a left conveyor belt, and the other end of the flexible belt is connected to a right conveyor belt.

[0012] Based on the above, the left winding shaft is connected to a left drive motor, and the right winding shaft is connected to a right drive motor.

[0013] The left and right winding shafts are respectively provided with slits for fixing the ends of the flexible strip.

[0014] Based on the above, the specifications of the left winding shaft and the right winding shaft are the same.

[0015] This invention represents a substantial improvement over existing technologies. Specifically, it provides a stockpiled rod-shaped material buffer storage device. By incorporating a flexible belt for flexibly storing rod-shaped materials on the underside of the conveyor channel, and connecting both ends of the flexible belt with a pair of winding shafts, the tension of the flexible belt can be controlled using these shafts. This allows for rapid adjustment of the amount of rod-shaped material stockpiled on the belt, achieving flexible buffering and rapid discharge of the material. Therefore, this device simplifies the structure of rod-shaped material buffer storage devices, reduces the footprint, lowers the failure rate, and improves the discharge efficiency of the buffered material.

[0016] Furthermore, by setting a detection container above the flexible belt and installing a flap and a rotation displacement sensor inside the detection container, the level of the rod-shaped material entering the detection container can be sensed in real time using the flap and the rotation displacement sensor. This allows for the control of the rotation direction of a pair of winding shafts based on the level of the rod-shaped material entering the detection container, enabling timely adjustment of the length of the flexible belt and achieving precise buffering of the rod-shaped material.

[0019] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0020] Example 1

[0021] This embodiment provides a stockpile-type rod-shaped material buffer storage device, such as... Figure 1 As shown, the system, installed on the conveying channel 1, includes a flexible belt 8, a left winding shaft 5, a right winding shaft 13, and a detection device. The flexible belt 8 is connected between the left winding shaft 5 and the right winding shaft 13 and is located below the conveying channel 1. It is used to adjust the amount of buffered rod-shaped material by changing its winding length. The detection device is located above the conveying channel 1 and above the flexible belt 8. It is used to sense the amount of rod-shaped material buffered on the flexible belt 8 and to change the winding length of the flexible belt 8 by controlling the rotation direction of the left winding shaft 5 and the right winding shaft 13.

[0022] Specifically, the detection device includes a controller, a detection container 2 with an open bottom, and a flap 3 rotatably disposed inside the detection container 2 for the rod-shaped material to be lifted. The detection container 2 is also provided with a rotational displacement sensor 4 for sensing the position of the flap 3, and the rotational displacement sensor 4 is signal-connected to the controller.

[0023] The controller is used to change the rotation direction of the left winding shaft 5 and the right winding shaft 13 according to the position of the flip plate 3 sensed by the rotation displacement sensor 4.

[0024] In this embodiment, a left push wheel 7 is provided on one side of the left winding shaft 5, and a right push wheel 11 is provided on one side of the right winding shaft 13. The left push wheel 7 and the right push wheel 11 are used to support the flexible belt 8.

[0025] Specifically, the left winding shaft 5 is driven by a left drive motor, and the right winding shaft 13 is driven by a right drive motor. The left winding shaft 5 and the right winding shaft 13 are each provided with slits for fixing the ends of the flexible tape. The left and right winding shafts are of the same specifications.

[0026] Example 2

[0027] This embodiment provides a stockpile-type rod-shaped material buffer storage device. The main difference from Embodiment 1 is that in this embodiment: a left pressure roller 6 is provided between the left winding shaft 5 and the left push wheel 7, and a right pressure roller 12 is provided between the right winding shaft 13 and the right push wheel 11. The left pressure roller 6 and the right pressure roller 12 are used to tension the two ends of the flexible belt 8.

[0028] Example 3

[0029] This embodiment provides a stockpile-type rod-shaped material buffer storage device. The main difference from Embodiment 1 is that in this embodiment, one end of the flexible belt 8 is connected to a left conveyor belt 10, and the other end of the flexible belt 8 is connected to a right conveyor belt 9.

[0030] Specifically, the working principle of the stockpiled rod-shaped material buffer storage device provided by this utility model is as follows:

[0031] The rod-shaped material produced by the upstream equipment is conveyed to the downstream equipment through the conveying channel 2. When the output speed of the rod-shaped material from the upstream equipment is greater than the receiving speed of the downstream equipment, the rod-shaped material enters the detection container 2, and the material level of the rod-shaped material increases, causing the flap 3 to rotate clockwise. The rotational displacement sensor 4 detects the position of the flap 3, and then the rotational displacement sensor 4 transmits a signal to the controller. The controller controls the left winding shaft 5 and the left propulsion wheel 7 to rotate clockwise, and controls the right winding shaft 13 and the right propulsion wheel 11 to rotate counterclockwise, so that the flexible belt 8 extends and moves downward. The enclosed space of the flexible belt 8 gradually increases, the buffer amount of the rod-shaped material increases, thereby reducing the supply of the rod-shaped material to the downstream equipment.

[0032] Conversely, when the output speed of the rod-shaped material from the upstream device is less than the receiving speed of the downstream device, the material level of the rod-shaped material in the detection container 2 moves downward, causing the flap 3 to rotate counterclockwise. The rotational displacement sensor 4 detects the position of the flap 3, and then the rotational displacement sensor 4 transmits a signal to the controller. The controller controls the left winding shaft 5 and the left push wheel 7 to rotate counterclockwise, and controls the right winding shaft 13 and the right push wheel 11 to rotate clockwise, so that the flexible belt 8 is tensioned and moved upward. The enclosing space of the flexible belt 8 gradually decreases, the buffer amount of the rod-shaped material decreases, and the supply of the rod-shaped material to the downstream device increases.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
