Description

Technical Field

[0001] The present invention relates to the technical field of cigarette production equipment, and in particular to a cigarette consumable material elevator and a use method thereof. Background Art

[0002] In the field of new cigarettes, especially in the filling and production process of granular heat-not-burn cigarettes, it is necessary to transport filter rod base rods, firmware base rods, paper tubes and other cigarette consumables to a second-floor platform about 2 meters high. The equipment on the second-floor platform performs online cutting and supplies the first-floor filling equipment to realize production operations. These cigarette consumables are generally carried manually or lifted to the second-floor platform by a forklift. However, the manual handling method has a small amount of materials carried each time, which affects the feeding efficiency of the second-floor platform. Workers carry materials while climbing stairs, which poses a great risk of safety accidents. Forklift loading and unloading of materials requires high operator requirements, and an additional forklift operator is required. A large space is required around the equipment to facilitate the rotation of the forklift. The production workshop occupies a large area. Each lift is observed by human eyes, which easily causes the risk of collision between the forklift and the platform, material falling and personal safety hazards.

[0003] At present, elevators generally use chains or wire ropes to lift materials. If the chain or wire rope breaks, the materials on the lifting frame will fall rapidly, causing equipment collision, material damage, and even injuries to personnel. The lifting frame generally adopts an integral welded structure, which is easy to deform after welding, and it is difficult to ensure the level of the bearing surface. The material will slide and fall during transportation. The gap between the two sets of pulleys and the guide shaft in the middle of the pulleys cannot be adjusted. The installation and removal of the guide shaft is complicated. The gap between the pulley and the guide shaft is large, and the equipment operation will generate large noise and vibration, which will affect the service life of the elevator. Summary of the invention

[0004] In view of the problems existing in the prior art, the present invention provides a cigarette consumables elevator and a method of use, which improves the existing method of transporting cigarette consumables and provides a new type of cigarette consumables elevator with compact structure, safe and reliable operation, simple operation, convenient equipment installation, materials not easy to fall during the lifting process, and adjustable preload force between the pulley and the guide shaft and elimination of gaps.

The upper end of the lead screw 205 is provided with a synchronous pulley 203, and the bottom is fixed with the bearing seat 209. The reduction motor 201 drives the lead screw 205 to rotate to realize the lifting function of the material.

[0038] Furthermore, the detection component 4 includes a first detection photoelectric 401, a second detection photoelectric 402 and a detection board 404.

[0042] Two adjustment plates 302 are provided at both ends of the lifting plate 304 , and multiple pairs of gap-adjustable pulleys 303 are provided on the two adjustment plates 302 . The guide shafts 206 are respectively arranged in the multiple pairs of gap-adjustable pulleys 303 of the two adjustment plates 302 and are slidably connected to the pulleys 303 .

[0044] In this embodiment, if Figure 5 As shown, the lifting plate 304 and the bracket 301 are installed in a nested manner and connected and fixed by a fixing bracket 306. Two adjustment vertical plates 302 are respectively arranged on both sides of the lifting plate 304, and are connected and fixed to the bracket 301 by a connecting seat 309. A total of eight pulleys 303 are provided, four of which are fixed on the eccentric pulley shaft 307, and the other four are fixed on the non-eccentric pulley shaft 308. The eccentric pulley shaft 307 and the non-eccentric pulley shaft 308 are installed on the two adjustment vertical plates 302.

[0045] The adjusting screw 305 is installed on the front side of the adjusted vertical plate 302, and the adjusting screw 305 can be pressed against the lifting plate 304. There is an adjustment gap between the contact position of the adjusting vertical plate 302 and the lifting plate 304, so that the horizontal relative position of the adjusting vertical plate 302 and the lifting plate 304 can be adjusted.

[0048] like Figure 7 As shown, the lifting plate 304 and the bracket 301 of this embodiment are fixed by nesting, which improves the matching strength, is easier to process than the welding structure, and reduces welding deformation.

[0049] Embodiment 2

[0050] The present invention provides a method for using a cigarette consumable material elevator, which is performed using a cigarette consumable material elevator as in the embodiment, and includes the following steps:

[0051] When the cigarette consumables are lifted, the materials are placed on the bracket 301 in the pallet assembly 3. Under the feedback of the second detection photoelectric 402 signal, the pallet assembly 3 is located at the starting position at the bottom of the main frame 101. During the lifting process, the limit stop bar 311 located on the front side of the pallet frame 301 can prevent the materials from slipping out. The reduction motor 201 drives the lead screw 205 to drive the pallet assembly 3 to lift at a uniform speed through the synchronous pulley 203. When the detection plate 404 fixed on the pallet assembly 3 approaches the first detection photoelectric 401 fixed on the main frame 101 and generates a feedback signal, the reduction motor 201 brakes, and the lead screw 205 stops driving the pallet assembly 3 to continue lifting. When it reaches the specified height position, the materials are moved out by the workers on the second-floor platform. The limit cross pipe 102 here can prevent the staff from falling into the elevator.

[0052] When the material is lowered, the material is placed above the cover plate 310 of the pallet assembly 3, the elevator descends, and the reduction motor 201 drives the lead screw 205 to rotate, so as to realize the uniform descent of the pallet assembly 3. When the detection plate 404 fixed on the pallet frame 301 approaches the second detection photoelectric 402, the reduction motor 201 brakes, and the pallet assembly 3 transports the material to the starting position. The worker takes out the material on the pallet assembly 3 and the operation is cyclically performed.

[0053] During the process of material rising and falling, when the first detection photoelectric 401 or the second detection photoelectric 402 fails, the third proximity switch 405 arranged above the main frame 101 and the fourth proximity switch 407 arranged below detect that the pallet assembly 3 reaches the specified height position and the starting position, and the reduction motor stops working;

[0054] When the material descends and the pallet assembly 3 descends beyond the starting position, the buffer 207 located on the main frame 101 can support the pallet assembly 3 to prevent it from colliding with the main frame 101.

[0055] The buffer 207 located on the main frame 101 can prevent the pallet assembly 3 from colliding with the main frame 101 when it fails. The third proximity switch 405 arranged above the main frame 101 and the fourth proximity switch 407 arranged at the bottom can prevent the reduction motor 201 from colliding with the elevator frame when the first detection photoelectric 401 and the second detection photoelectric 402 fail, thereby further improving the safety and stability during the lifting process.

[0056] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without creative work are still within the scope of protection of the present invention.
