Description

Technical Field

[0001] This utility model relates to the technical field of turning wheel mechanisms, specifically a turning wheel mechanism with a precise repositioning structure. Background Technology

[0002] The turning wheel is an important component of the cigarette rolling machine. In the initial stage of cigarette production, two cigarette filters are joined together and need to be guided to the turning wheel by the conveyor drum. The turning wheel then passes the filters to the detection drum. The function of the turning wheel is to turn the two rows of opposing filter cigarettes into a row of filter cigarettes facing the same direction.

[0003] For example, announcement number CN210169036U (named "A Turning Wheel for a Cigarette Machine") includes a rotating shaft. A fitting ring is fixed to the outer surface of the rotating shaft via a fitting assembly. The fitting assembly includes a fitting strip and a concave groove. The fitting strip is integrally formed on the outer wall of the rotating shaft, and the concave groove is formed on the inner wall of the fitting ring. The fitting ring is sleeved on the rotating shaft via the concave groove and the fitting strip. A sealing cap is placed on the upper surface of the fitting ring, and a bolt post is mounted on the lower surface of the sealing cap above the rotating shaft. The top of the bolt post penetrates the sealing cap. A nut is screwed onto the side surface of the bolt, and a rotating finger is connected to the side surface of the fitting ring via a connector. A fitting strip is added to the side of the rotating shaft, and a concave groove is added to the inner wall of the fitting ring. The fitting ring is fixed to the side of the rotating shaft by the cooperation of the fitting strip and the concave groove, which facilitates the disassembly and installation of the fitting ring by the staff. A rubber ring improves the stability of the fitting ring when it is placed. A bearing ring is added to the outer surface of the extension ring. The bearing ring improves the lubrication when the rotating finger rotates, avoids uneven rotation of the rotating finger, avoids the phenomenon of cigarettes falling off and empty ends, and improves the quality of cigarettes.

[0004] The aforementioned turning wheel improves the smoothness of the rotating finger's rotation through the designed bearing ring structure during use. However, it lacks an effective limiting mechanism when the rotating finger carries the cigarette and turns around, resulting in poor accuracy in cigarette turning and repositioning. To address this, we provide a turning wheel mechanism with a precise repositioning structure. Utility Model Content

[0005] The purpose of this utility model is to provide a turning wheel mechanism with a precise repositioning structure to solve the problem mentioned in the background art that the existing turning wheel improves the smoothness of the rotating finger through the setting of the bearing ring structure, but lacks an effective limiting mechanism when the rotating finger carries the cigarette to turn around, resulting in poor accuracy of cigarette turning and repositioning.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a turning wheel mechanism with a precise repositioning structure, including a connecting seat, a turning wheel at the upper end of the connecting seat, a fan-shaped block integrally formed on the outer wall of the turning wheel, an adsorption groove on the outer wall of the fan-shaped block, a transfer seat at one side above the adsorption groove, the transfer seat and the turning wheel being an integral structure, and a rotating finger welded to one end of the transfer seat; Also includes: An internal circular groove is located at the top center of the turning wheel, and a drive motor is installed inside the internal circular groove. A turntable seat is welded onto the output shaft of the drive motor. An extension shaft is integrally formed on the front outer wall of the turntable seat, and a sleeve frame is sleeved on the outside of the extension shaft. The top ring seat is located outside the built-in circular groove, and a limit stop is provided on one side of the outer wall of the rotating finger. A connecting rod is welded between the limit stop and the top ring seat. The movable frame is located at the front end of the sleeve frame and the turntable seat, and a linkage rod is welded between the movable frame and the sleeve frame. Both ends of the movable frame are welded with internal sliders.

[0007] Preferably, lifting slides are provided on both inner walls of the built-in circular groove, and the two inner sliders are connected to the built-in circular groove for lifting and moving through the two lifting slides.

[0008] Preferably, both inner sliders are equipped with auxiliary rollers that are movably arranged inside the sliders via bearings and connecting shafts, and the inner sliders are connected to the lifting grooves via the auxiliary rollers.

[0009] Preferably, two mounting rods are provided between the two inner sliders and the top ring seat, and the two ends of the mounting rods are welded to the inner sliders and the top ring seat respectively.

[0010] Preferably, there are twenty-two adsorption tanks and twenty-two rotating fingers, and the twenty-two adsorption tanks and the sector block are an integral structure.

[0011] Preferably, the adsorption tank and the rotating finger are located on the same straight line, and the rotating finger is rotatably connected to the turning wheel through an adapter.

[0012] Preferably, the lower end of the drive motor is glued and fixedly mounted with a motor carrier, and the motor carrier is fixedly connected to the built-in circular groove by screws.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention uses a drive motor to rotate the turntable base, which in turn causes the sleeve frame to move up and down along the extension shaft, reciprocating. This, in turn, causes the movable frame and the top ring seat to move up and down synchronously, and also causes the limit block to move up and down. When the limit block is lowered, it limits the rotation of the rotating finger. When the limit block is raised, the rotating finger can rotate back to the position parallel to the adsorption tank, and pick up the cigarette again for repositioning. By limiting the rotation range of the rotating finger by the limit block, the rotating finger is restricted to a 180-degree rotation position, preventing the rotating finger from deviating when rotating and repositioning with the cigarette, thus improving the accuracy of repositioning. This overcomes the problem that existing turning wheels improve the smoothness of the rotating finger's rotation through the setting of a bearing ring structure, but lack an effective limiting mechanism when the rotating finger is rotating and repositioning with the cigarette, resulting in poor accuracy of cigarette repositioning.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Please see Figure 1-4 An embodiment of this utility model is provided: a turning wheel mechanism with a precise repositioning structure, including a connecting seat 1, a turning wheel 2 is provided at the upper end of the connecting seat 1, a fan-shaped block 3 is integrally formed on the outer wall of the turning wheel 2, an adsorption groove 4 is provided on the outer wall of the fan-shaped block 3, an adapter seat 5 is provided on one side above the adsorption groove 4, the adapter seat 5 and the turning wheel 2 are integrally formed, and a rotating finger 6 is welded to one end of the adapter seat 5; Also includes: The built-in circular groove 10 is located at the top center of the turning wheel 2, and a drive motor 13 is installed inside the built-in circular groove 10. A turntable seat 16 is welded to the output shaft of the drive motor 13. An extension shaft 18 is integrally formed on the front outer wall of the turntable seat 16, and a sleeve frame 19 is sleeved on the outside of the extension shaft 18. The top ring seat 8 is located on the outside of the built-in circular groove 10, and a limit stop 7 is provided on one side of the outer wall of the rotating finger 6. A connecting rod 9 is welded between the limit stop 7 and the top ring seat 8. The movable frame 14 is located at the front end of the sleeve frame 19 and the turntable seat 16, and a linkage rod 20 is welded between the movable frame 14 and the sleeve frame 19. Both ends of the movable frame 14 are welded with internal sliders 17.

[0017] In use, the rotation range of the rotating finger 6 is limited by the limiting block 7, so that the rotating finger 6 is restricted to a 180-degree rotation position, which prevents the rotating finger 6 from deviating when rotating and changing the position of the cigarette, thus improving the accuracy of the position. The rotating finger 6 rotates 180 degrees and keeps it in the same straight line with the adsorption tank 4, thereby turning the two rows of opposite filter cigarettes into a row of filter cigarettes facing the same direction. The drive motor 13 drives the turntable seat 16 to rotate, thereby driving the sleeve frame 19 to move up and down along the extension shaft 18, which in turn drives the movable frame 14 and the top ring seat 8 to move up and down and back and forth synchronously, and drives the limiting block 7 to move up and down and back and forth. When the limiting block 7 is lowered, it limits the rotation of the rotating finger 6. When the limiting block 7 is raised, the rotating finger 6 can rotate back to the position parallel to the adsorption tank 4, and pick up the cigarette again for repositioning.

[0018] Please see Figure 4 The inner walls on both sides of the built-in circular groove 10 are provided with lifting slide grooves 11. Two inner sliders 17 are connected to the built-in circular groove 10 via the two lifting slide grooves 11.

Figure 4 Each of the two inner sliders 17 has an auxiliary roller 21 movably mounted inside via bearings and connecting shafts. The inner sliders 17 are rolledly connected to the lifting slide 11 via the auxiliary rollers 21. The auxiliary rollers 21, which are movably mounted inside the two inner sliders 17 via bearings and connecting shafts, assist in the smooth movement of the inner sliders 17 and the lifting slide 11. Please refer to... Figure 1 and Figure 4 Two connecting rods 12 are provided between the two inner sliders 17 and the top ring seat 8. The two ends of the connecting rods 12 are welded to the inner sliders 17 and the top ring seat 8 respectively. The two connecting rods 12 between the two inner sliders 17 and the top ring seat 8 serve to connect the inner sliders 17 and the top ring seat 8. Please refer to [link / reference].
