Description

Technical Field

[0001] This utility model relates to the field of tobacco manufacturing equipment technology, specifically to a rod-shaped material extraction device. Background Technology

[0002] In the composite rod forming process, the rod-shaped material enters the slitting device through the hopper for slitting, then needs to be transferred to the conveyor track for composite gap elimination, and finally fed into the forming gun to be rolled and cut into specified lengths. However, when the slitting rods are output from the circumferential groove of the slitting hub to the conveyor track, the significant changes in the conveying trajectory, angle, and height can easily cause rod blockage, directly restricting the rod conveying efficiency and the improvement of forming speed.

[0003] Existing rod-shaped material extraction technologies have the following shortcomings:

[0004] 1. The uneven transition between the slitting hub and the conveyor track causes the rod-shaped object to easily get stuck or deviate during the transfer process;

[0005] 2. Traditional extraction devices lack multi-dimensional adjustment mechanisms, making it difficult to adapt to the production needs of rod-shaped materials of different specifications;

[0006] 3. The chain tensioning mechanism is not stable enough and is prone to loosening during long-term operation, which affects the extraction accuracy and equipment reliability.

[0007] These problems directly lead to increased rod blockage rate and increased equipment maintenance frequency, which restricts the improvement of production line efficiency and product quality stability. Utility Model Content

Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0038] Example:

[0039] Please refer to the example below. Figure 1-7 As shown, this embodiment provides a rod-shaped object extraction device, including a horizontal angle adjustment device 1, a lifting device 2, a conveying device 3, and a horizontal adjustment frame 4; the horizontal angle adjustment device 1 is fixedly installed on the original machine frame with adjustable horizontal angle to realize the horizontal angle adjustment of the conveying device 3; the horizontal adjustment frame 4 is slidably connected to the top surface of the horizontal angle adjustment device 1 to realize the horizontal position adjustment of the conveying device 3; the lifting device 2 is fixedly installed on the top of the horizontal adjustment frame 4; the conveying device 3 is slidably connected to one side of the lifting device 2 in the vertical direction and its own height position is adjusted by the horizontal adjustment frame 4.

[0040] The conveying device 3 is equipped with an extraction chain 38. Several chain hooks 381 are equidistantly arranged on the surface of the extraction chain 38. The chain hooks 381 move the rod-shaped object in the circumferential groove of the original machine cutting hub wheel and make the rod-shaped object follow the running trajectory of the extraction chain 38 and be conveyed downward.

[0041] Specifically, such as Figure 1 As shown, this extraction device adjusts the rotation angle of the device on the horizontal plane of the original machine frame by adjusting the horizontal angle adjustment device 1, thereby adjusting the angle between the conveyor device 3 and the original machine cutting hub. After the angle is adjusted, it is fastened to the original machine frame with screws to maintain the adjusted connection posture. At the same time, the horizontal adjustment frame 4 is slidably connected to the top surface of the horizontal angle adjustment device 1 to realize its own horizontal adjustment function, thereby realizing the horizontal distance adjustment between the conveyor device 3 and the cutting hub. In addition, by setting the lifting device 2 in the middle of the horizontal adjustment frame 4 and sliding the conveyor device 3 vertically to the top surface of the horizontal adjustment frame 4, the lifting device 2 drives the lifting adjustment of the conveyor device 3, so that the extraction chain 38 matches the circumferential groove of the original machine cutting hub in the vertical direction. Through multi-dimensional adjustment settings, the adjustable range of this device is wide, thereby effectively improving the extraction accuracy of the conveyor device 3 for rod-shaped objects, effectively preventing rod blockage in the production line process, and ensuring the normal operation of the production line.

[0042] In a preferred embodiment of this utility model, the horizontal angle adjustment device 1 further includes an angle adjustment plate 11. One end of the angle adjustment plate 11 is provided with a fulcrum screw 15. The angle adjustment plate 11 is rotatably connected to the original machine frame with the fulcrum screw 15 as the origin, and is fastened to the original machine frame through the fulcrum screw 15. An adjustment arc groove 111 is opened in the middle of the other end of the angle adjustment plate 11. A circular arc rack 12 is fixedly installed on the bottom surface of the angle adjustment plate 11 along the arc length side of the adjustment arc groove 111. The concave tooth surface of the circular arc rack 12 meshes with an adjustment gear 13. The adjustment gear 13 is fixedly installed on the handwheel 14 near the bottom end. The middle part of the handwheel 14 is located in the adjustment arc groove 111, and its bottom is connected to the bearing of the original machine frame. After the horizontal angle of the angle adjustment plate 11 is adjusted, it is fastened to the original machine frame through bolts to fix the position.

[0043] Specifically, such as Figure 2 As shown, by rotating the handwheel 14, the adjusting gear 13 is driven to rotate. Since the handwheel 14 is connected to the original machine frame, the adjusting gear 13 drives the arc rack 12 to rotate coaxially, thereby driving the angle adjusting plate 11 fixedly installed with it to rotate around the fulcrum screw 15 as the origin, thereby adjusting the connection angle between the extraction device and the original machine frame as a whole. After the adjustment is completed, the original machine frame is fixed by tightening all the screws, including the fulcrum screw 15.

[0044] In a preferred embodiment of the present invention, the horizontal adjustment frame 4 further includes a mounting frame 41. The bottom opposite sides of the mounting frame 41 are fixedly mounted on the top surface of the angle adjustment plate 11 by two sets of first linear guide rail assemblies 43. A quick clamp assembly 42 is provided at the bottom of the mounting frame 41 corresponding to the first linear guide rail assembly 43. The mounting frame 41 is fixed in position by clamping the guide rail of the first linear guide rail assembly 43 by the quick clamp assembly 42.

[0045] Specifically, such as Figure 2 As shown, by connecting the angle adjustment plate 11 and the mounting frame 41 through two sets of first linear guide rail assemblies 43, the mounting frame 41 can slide in the horizontal direction. By installing quick clamp assembly 42 at the bottom of the mounting frame 41 corresponding to the first linear guide rail assembly 43, and by rotating the handle of the quick clamp assembly 42 to lock it with the guide rail, the horizontal position of the mounting frame 41 is fixed, thereby realizing the adjustment and fixing function of the horizontal position of the mounting frame 41.

[0046] In a preferred embodiment of this utility model, the lifting device 2 further includes two mounting brackets 21, which are fixedly installed on the top surface of the mounting frame 41 at intervals in the horizontal direction. A crossbar 23 is fixedly installed between the two mounting brackets 21. A second linear guide rail 22 is provided on one side of the mounting bracket 21 in the vertical direction. The conveying device 3 is fixedly installed between the two mounting brackets 21 through two sets of second linear guide rails 22. A lifting cylinder 25 is provided in the middle of the two mounting brackets 21 in the vertical direction. The lifting cylinder 25 is fixedly installed on the top surface of the mounting frame 41 through a cylinder support 26. A connecting lug 24 is provided at the shaft end of the lifting cylinder 25, and the other end is fixedly installed with the conveying device 3.

[0047] Specifically, such as Figure 3 As shown, the lifting cylinder 25 drives the conveying device 3 to move vertically along the length of the second linear guide rail 22, thereby precisely adjusting the vertical height of the conveying device 3.

[0048] In a preferred embodiment of this utility model, the conveying device 3 further includes a drive sprocket assembly 31, a horizontal adjustment sprocket assembly 33, and a vertical adjustment sprocket assembly 37. The drive sprocket assembly 31, the horizontal adjustment sprocket assembly 33, and the vertical adjustment sprocket assembly 37 are arranged in a triangular distribution on one side of the fixed plate 39. The horizontal adjustment sprocket assembly 33 and the vertical adjustment sprocket assembly 37 are adjusted in the horizontal and vertical directions, respectively. The extraction chain 38 is wrapped around the outside of the drive sprocket assembly 31, the horizontal adjustment sprocket assembly 33, and the vertical adjustment sprocket assembly 37 in a loop shape. It is driven by the drive sprocket assembly 31 to rotate and remove the rod-shaped object from the original machine. The surface of the fixed plate 39 is provided with a tension sprocket assembly 32. The extraction chain 38 is tensioned by adjusting the position of the tension sprocket assembly 32.

[0049] In a preferred embodiment of the present invention, the fixed plate 39 is further provided with a driven wheel assembly 36 for assisting in supporting the extraction chain 38 and a chain upper guide rail 35 near the vertical adjustment sprocket assembly 37, and the extraction chain 38 slides on the top surface of the chain upper guide rail 35.

[0050] In a preferred embodiment of the present invention, the drive sprocket assembly 31 further includes a main sprocket 311, a coupling 312, a reducer 313, and a servo motor 314; the servo motor 314 is connected to the reducer 313 by bearings, the shaft of the main sprocket 311 is fixedly installed to the shaft of the reducer 313 through the coupling 312, and the coupling 312 is fixedly installed to the fixing plate 39.

[0051] In a preferred embodiment of this utility model, the vertical adjustment sprocket assembly 37 further includes an adjustment shaft seat 372. The fixing plate 39 is provided with a vertical adjustment groove 392 and a horizontal adjustment groove 391 respectively, corresponding to the horizontal adjustment sprocket assembly 33 and the vertical adjustment sprocket assembly 37. The adjustment shaft seat 372 is slidably connected to the vertical adjustment groove 392. An adjustment bolt 373 is threadedly connected to the middle of the adjustment shaft seat 372 in the vertical direction. The adjustment bolt 373 is connected to the fixing plate 39 bearing to realize the vertical movement of the adjustment shaft seat 372 in the vertical adjustment groove 392. The adjustment shaft seat 372 is fastened to the fixing plate 39 by bolts. A small sprocket 371 is connected to the front end bearing of the adjustment shaft seat 372. The small sprocket 371 meshes with the extraction chain 38.

[0052] In a preferred embodiment of the present invention, the structure of the horizontal adjustment sprocket assembly 33 is exactly the same as that of the vertical adjustment sprocket assembly 37. The difference is that the adjustment shaft seat 372 of the horizontal adjustment sprocket assembly 33 is slidably connected in the horizontal adjustment groove 391 to realize the horizontal movement of the large sprocket 331 of the horizontal adjustment sprocket assembly 33 in the horizontal adjustment groove 391.

[0053] Specifically, such as Figure 4-7 As shown, the installation positions of the vertical sprocket assembly 37 and the horizontal sprocket assembly 33 are adjustable, and the extraction sprocket is kept taut by the cooperation of the drive sprocket assembly 31 and the tensioning sprocket assembly 32. This prevents the extraction chain 38 from being too loose, which would cause the chain hook 381 to not be in a blocking position and affect the extraction action of the rod-shaped object, thus reducing the production efficiency of the device.

[0054] Specifically, by rotating the adjusting bolt 373, the adjusting shaft seat 372, which is threadedly connected to it, is driven to slide within the vertical adjusting groove 392, thereby adjusting the vertical position of the small sprocket 371. Then, the adjusting shaft seat 372 is fastened to the fixing plate 39 with screws to fix its position. Similarly, the horizontal adjusting sprocket assembly 33 is adjusted to change the horizontal position of the large sprocket 331, thereby achieving the tightening and fine-tuning of the sprocket position. After the adjustment is completed, the servo motor 314, in conjunction with the reducer 313, drives the main sprocket 311 to rotate slowly, thereby driving the extraction chain 38 to move each chain hook 381 along its motion trajectory to extract the rod-shaped object inside the machine.

[0055] The working principle of this rod-shaped object extraction device is as follows: After the device is fixed on the original machine frame, according to the relative position of the extraction chain 38 and the circumferential groove of the cutting hub wheel, the horizontal position of the conveying device 3 on the original machine is first adjusted by the horizontal adjustment frame 4 in conjunction with the first linear guide rail assembly 43 and the quick clamp assembly 42. Then, the horizontal angle adjustment plate 11 and the horizontal angle of the original machine are adjusted by rotating the handwheel 14 of the horizontal angle adjustment device 1, thereby adjusting the horizontal angle of the extraction chain 38 and the cutting hub wheel groove on the conveying device 3. Then, the height difference between the extraction chain 38 and the cutting hub wheel groove is adjusted by the extension and retraction of the lifting cylinder of the lifting device 2, so that the distance between the extraction chain 38 and the cutting hub wheel groove is at the height of the rod-shaped object extraction. Then, the positions of the horizontal adjustment sprocket assembly 33, the vertical adjustment sprocket assembly 37 and the tensioning sprocket assembly 32 are adjusted in sequence so that the extraction chain 38 always maintains constant tension and is perpendicular to the cutting hub wheel groove to extract the rod-shaped object.

[0056] In addition, when repairing or adjusting the device, simply retract the lifting cylinder, lower the conveying device 3 to the lowest position, loosen the quick clamp assembly 42 on the fixed guide rail of the horizontal angle adjusting device 1, and move the device to the rear end of the first linear guide rail assembly 43.

[0057] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
