Abstract
The utility model discloses an overload protector of a flattening disc driving system, which comprises a synchronous belt (1), a synchronous pulley and a main drive shaft (4) of the synchronous pulley, wherein the synchronous pulley is composed of an outer wheel (6) and an inner wheel (3) which are coaxial and are in rotation joint; the inner wheel (3) is fixed on the main drive shaft (4), the synchronous belt (1) is sheathed on the outer wheel (6), and a safety pin (7) is arranged between the outer wheel (6) and an inner wheel (3). The utility model is the overload protection device of a flattening disc driving system, which can make the flattening disc driving system automatically disengage the drive when the flattening disc is clamped by sundries and has the advantages of simple structure, easy fabrication, low cost and reliable performance.
Description
Technical field
The utility model relates to a kind of overload protection arrangement, particularly relates to a kind of smooth dish transmission system overload protection arrangement.
Background technology
As the smooth dish of control cigarette weight, its transmission is to import smooth dish gear-box from main-gear box into by synchronous cog belt, synchronous pulley and final drive shaft thereof, again by smooth dish of gear drive in the smooth dish gear-box and the action of brush silk wheel.During smooth dish work,, directly unnecessary pipe tobacco is pruned by a smooth dish and the acting in conjunction of brush silk wheel.When containing non magnetic foreign material (as stone, plastic sheet, stainless steel screw, brass screw etc.) in the pipe tobacco, smooth dish is stuck by foreign material, will cause the synchronous belt in the smooth dish transmission system, smooth dish, brush silk wheel and each travelling gear to damage, generally can cause several ten thousand yuan economic loss and breakdown maintenance for a long time, and influence the transmission accuracy of transmission system, make tight position of smooth dish when operation, fluctuation occur, thereby influence cigarette short and Cigarette Weight Control precision.
The utility model content
Technical problem to be solved in the utility model provide a kind of when smooth dish is stuck by foreign material smooth dish transmission system can throw off the smooth dish transmission system overload protection arrangement of transmission automatically.
In order to solve the problems of the technologies described above; the technical solution adopted in the utility model is: smooth dish transmission system overload protection arrangement; comprise synchronous band; synchronous pulley and final drive shaft thereof; it is characterized in that: described synchronous pulley is made up of foreign steamer coaxial and rotational engagement each other and interior wheel; wheel is packed on the described final drive shaft in described, and described synchronous band is sleeved on the described foreign steamer, is provided with safety pin between described foreign steamer and interior wheel.
As a kind of improvement of the present utility model, the rotational engagement place between described foreign steamer and interior wheel is provided with needle bearing.
Be provided with spring between described safety pin and the described interior wheel, and the preshearing fault trough of described safety pin is provided with the safety screw cover corresponding with described safety pin corresponding to the joint of described foreign steamer and interior wheel on described foreign steamer.
Adopt the smooth dish transmission system overload protection arrangement of technique scheme; synchronous pulley on the final drive shaft of smooth dish transmission system is made up of foreign steamer coaxial and rotational engagement each other and interior wheel; interior wheel is packed on the final drive shaft; between foreign steamer and interior wheel, be provided with safety pin; when containing foreign material in the pipe tobacco and block smooth dish; final drive shaft can not rotate; when synchronous band drives load that the foreign steamer of synchronous pulley rotates greater than the safety value of safety pin; safety pin disconnects; thereby the foreign steamer of synchronous pulley and interior wheel are thrown off transmission automatically; thereby smooth dish transmission system is thrown off automatically, reach the drive disk assembly of the smooth dish transmission system of automatic protection and the purpose of transmission accuracy.The utility model highly versatile only needs to change inside/outside diameter size of the present utility model, just can adapt to various types.
In sum, the utility model be a kind of when smooth dish is stuck by foreign material smooth dish transmission system can throw off transmission and smooth dish transmission system overload protection arrangement simple in structure, easily manufactured, cheap, dependable performance automatically.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
Referring to accompanying drawing, synchronous pulley is made up of foreign steamer 6 coaxial and rotational engagement each other and interior wheel 3, interior wheel 3 is packed on the final drive shaft 4, be with 1 to be sleeved on the foreign steamer 6 synchronously, be provided with safety pin 7 between foreign steamer 6 and interior wheel 3, the rotational engagement place between foreign steamer 6 and interior wheel 3 is provided with needle bearing 2, is provided with spring 5 between safety pin 7 and the interior wheel 3, and the preshearing fault trough 9 of safety pin 7 is corresponding to the joint of foreign steamer 6 and interior wheel 3, is provided with the safety screw cover 8 corresponding with safety pin 7 on foreign steamer 6.
When containing foreign material in the pipe tobacco and block smooth dish; final drive shaft 4 can not rotate; when the load of rotating with 1 foreign steamer 6 that drives synchronous pulley synchronously during greater than the safety value of safety pin 7; safety pin 7 disconnects; thereby foreign steamer 6 and interior wheel 3 are thrown off transmission automatically; thereby smooth dish transmission system is thrown off automatically, reach the drive disk assembly of the smooth dish transmission system of automatic protection and the purpose of transmission accuracy.Be provided with spring 5 between safety pin 7 and the interior wheel 3, be provided with the safety screw cover 8 corresponding with safety pin 7 on foreign steamer 6, after safety pin 7 disconnects, when needing to change safety pin 7, open safety screw cover 8, spring 5 ejects safety pin 7, is convenient to change safety pin 7.
