[0029] As attached Figure 1-Figure 4 As shown, a material centering device for a slicer inlet conveyor belt comprises: a detection component 1, which is arranged at the inlet of the conveyor belt 6 and is used to check whether the material entering the inlet of the conveyor belt 6 is centered; a guide rail 2, which is arranged below the conveyor belt 6 and extends to the outside of both sides of the conveyor belt 6; a pushing assembly 3, on which two pushing assemblies 3 arranged outside both sides of the conveyor belt 6 are slidably mounted, and the pushing assemblies 3 are arranged on both sides of the outside of the conveyor belt 6, and the adjacent sides of the two pushing assemblies 3 are provided with a pushing plate 31 which can horizontally extend above the conveyor belt 6; a driving device 4, on which two driving devices 4 are provided on the guide rail 2 and respectively drive the two pushing assemblies 3 to slide; a jet cleaner 5, which is provided on the pushing plate 31.

[0030] In the material centering device of the conveyor belt at the entrance of the slicer, a detection component 1 is set at the conveyor belt 6 at the entrance of the slicer. The detection component 1 can check whether the material on the conveyor belt 6 is located in the middle. If the detection component 1 detects that the material is close to the edges of both sides of the conveyor belt 6, the detection component 1 sends a signal to the controller, and the controller controls the drive device 4 to start. The drive device 4 starts the two pushing components 3 on the guide rail 2 to slide relative to each other. The push plates 31 on the two pushing components 3 push the material located on the side of the conveyor belt 6 to the middle, so that the material is arranged in the center on the conveyor belt 6, so that when the conveyor belt 6 transports the material to the entrance of the slicer, the slicer can cut the material neatly.

[0031] In the material centering device of the slicer inlet conveyor belt, a jet cleaner 5 is arranged on the push plate 31, and the jet cleaner 5 can spray gas to purge the push plate 31, so that the push plate 31 is kept clean.

[0032] In this embodiment, the pusher assembly 3 includes a moving seat 32, a support 33 disposed on the moving seat 32, and a push plate 31 disposed on the top of the support 33. The moving seat 32 is slidably connected to the guide rail 2. The moving seat 32 is slidably mounted on the guide rail 2 and can stably slide horizontally on the guide rail 2. The support 33 is vertically fixed on the moving seat 32. The push plate 31 on the top of the support 33 is located higher than the conveyor belt 6. When the two moving seats 32 move toward each other, the push plate 31 can extend above the conveyor belt 6 to push the material on the conveyor belt 6 to the middle position.

[0033] In this embodiment, a buffer component 7 is provided between the push plate 31 and the support 33, and the buffer component 7 includes a slide bar 71 and a spring 72. One end of the slide bar 71 is fixedly connected to the push plate 31, and the other end of the slide bar 71 is slidably connected to the support 33 and provided with a limit nut 73. The spring 72 is sleeved on the slide bar 71. The buffer component 7 is provided on the push plate 31, so that when the push plate 31 is subjected to resistance, the push plate 31 can shrink outward, which can reduce the impact force when the push plate 31 contacts the material, and when the push plates 31 on both sides squeeze and push the two sides of the material at the same time, the two push plates 31 can automatically shrink outward to avoid clamping the material.

[0034] In this embodiment, a mounting groove 34 is provided on the inner side of the push plate 31. The mounting groove 34 is a laterally slotted aluminum alloy profile structure. The cross-section of the aluminum alloy profile structure is U-shaped. A plurality of roller assemblies 35 are provided in the mounting groove 34. Both ends of the mounting groove 34 are provided with inclined portions extending outward. The inclined portions play a guiding role. A trumpet-mouth structure is formed at both ends of the mounting grooves 34 on both sides, so that the cigarette package material can automatically slide into the area between the two push plates 31 when it is conveyed forward with the conveyor belt 6. The setting of the roller assembly 35 can prevent the cigarette package material from having dry friction with the push assembly 3 when it moves with the conveyor belt 6, avoid excessive scratches on the cigarette package material, and reduce the raw material consumption of the tobacco package material during transportation.

[0035] In this embodiment, the jet cleaner 5 includes a cleaning pipe 51 arranged above the push plate 31 and an air nozzle 52 arranged at the bottom of the cleaning pipe 51 and inserted into the mounting groove 34. One end of the cleaning pipe 51 is provided with an air inlet 53 connected to the air supply pipe. The air supply pipe is provided with an electromagnetic valve electrically connected to the controller. When the roller of the roller assembly 35 comes into contact with the cigarette pack material, some tobacco fragments will adhere to the roller. The controller controls the air nozzle 52 of the jet cleaner 5 to perform pulse cleaning on the gap between the rollers, so that the rollers remain clean and tidy, preventing the rollers from rotating poorly due to the adhesion of too many foreign objects, ensuring that the rollers can roll normally, and avoiding sliding friction between the rollers and the cigarette pack material due to the inability to rotate.

[0036] In this embodiment, the driving device 4 includes a servo motor 41 and a screw rod 42, a coupling is provided between the output shaft of the servo motor 41 and the screw rod 42, the screw rod 42 is rotatably installed in the guide rail 2 through a bearing, the moving seat 32 is threadedly connected to the screw rod 42 through a screw nut, the servo motor 41 is provided on the side of the guide rail 2, and the output end of the servo motor 41 is transmission-connected to the screw rod 42. The servo motor 41 drives the screw rod 42 to rotate, and the rotation of the screw rod 42 drives the moving seat 32 to slide stably under the guidance of the guide rail 2.

[0037] In this embodiment, mounting plates 21 are provided on both sides of the guide rail 2, and the servo motor 41 is fixedly mounted on the mounting plates 21. The mounting plates 21 are mounted on the cut surfaces on both sides of the guide rail 2, and the end faces of the servo motor 41 are fixedly connected to the mounting plates 21 through a bolt structure.

[0038] In this embodiment, the opposite sides of the two movable seats 32 are provided with an accordion cover 9 connected to the mounting plate 21, and the adjacent sides of the two movable seats 32 are connected with the accordion cover 9, and the accordion cover 9 can wrap the outer contour surface of the guide rail 2. When the two movable seats 32 slide on the guide rail 2, the accordion covers 9 on the two movable seats 32 always wrap the track of the guide rail 2 to prevent the lead screw in the guide rail 2 from being exposed, to prevent tobacco fragments and dust from entering the guide rail 2, and to prevent tobacco fragments and dust from entering the gap between the lead screw 42 and the lead screw nut, thereby ensuring that the lead screw 42 and the lead screw nut can rotate smoothly relative to each other and ensuring smooth lead screw transmission.

[0039] In this embodiment, two guide brackets 8 are provided on the outside of both ends of the movable seat 32, and guide grooves 81 are provided at the adjacent ends of the tops of the two guide brackets 8, and sliders 36 adapted to the guide grooves 81 are provided on both end surfaces of the top of the support 33. The guide grooves 81 on the guide brackets 8 are slidably connected with the sliders 36 at the top of the support 33, guiding the top of the support 33 to ensure that the entire pusher assembly 3 can move stably horizontally.

[0040] In this embodiment, a support plate 82 is provided at the bottom end of the guide bracket 8, and a support rod 83 is connected to the bottom of the two guide brackets 8 located on the same side of the guide rail 2. The guide rail 2 is installed on the support rod 83, and the guide rail 2 is fixed on the support rod 83 by bolts.

[0041] In this embodiment, the detection component 1 includes a gantry 11 and two photoelectric detection switches 12. The photoelectric detection switch 12 is a diffuse reflection detection switch, which can effectively detect the deflection of the material. The two support columns of the gantry 11 are arranged on the side of the conveyor belt 6, and the two photoelectric detection switches 12 are symmetrically arranged on the cross bar at the top of the gantry 11.

[0042] Working principle:

[0043] The photoelectric detection switch 12 on the gantry 11 monitors the cigarette pack material on the conveyor belt 6. When the photoelectric detection switches 12 on both sides can detect the cigarette pack at the same time, the material centering device is not triggered; when only the detection switch on one side detects the cigarette pack, the photoelectric detection switch 12 gives a signal to the controller system, and the controller sends a signal to control the servo motor 41 of the drive device 4 to start, drive the screw rod 42 to rotate, and when the screw rod 42 rotates, it drives the moving seat 32 to slide stably under the guidance of the guide rail 2, and the push plate 31 on the moving seat 32 pushes the material located on the side of the conveyor belt 6 to the middle, so that the material is arranged in the center of the conveyor belt 6, so as to realize the correction of the cigarette pack. After the correction is completed, the controller controls the solenoid valve on the air supply pipe to open, and injects compressed air into the cleaning pipe 51. The gas is ejected from the air nozzle 52 to realize the pulse cleaning of the roller. After the cleaning is completed, the servo motor 41 of the drive device 4 is started to drive the push plate 31 to retreat.
