Detailed Description
The present invention will be further described with reference to fig. 1 to 3.
As shown in the figure, the swing arm type mechanical braking caching and releasing mechanism comprises a rack 1, wherein a tape reel 3 and a fixed arm 5 are respectively connected to the rack 1, the tape reel 3 is connected with the rack 1 through a rotating shaft, one end of the rotating shaft is connected with the tape reel 3, and the other end of the rotating shaft is connected with a braking mechanism 2; the brake mechanism 2 comprises a tension spring 21, the tension spring 21 is connected with a pull rod 24, a hollow rotating pin 22 and a gasket 23 which are matched with each other are arranged on the pull rod 24, the hollow rotating pin 22 is pressed to the gasket 23 through the pull rod 24, and the hollow rotating pin 22 is connected with the lower swing arm 4; one end of the pull rod 24 is connected with the tension spring 21, the other end of the pull rod is connected with the belt 25, and the belt 25 is connected with the rack 1 through a belt pulley 26; and an upper wheel disc 7 and a lower wheel disc 6 are fixedly connected to the fixed arm 5 and the lower swing arm 4 respectively.
The machine frame 1 provides stable support for the whole mechanism, the braking mechanism 2 is connected with the belt reel 3 through a rotating shaft, and the release and braking of the belt reel 3 are automatically controlled; the lower swing arm 4 is connected with the frame 1 through a hollow rotating pin of the braking mechanism, so that pendulum motion around the rotating shaft is realized; the fixing arm 5 is connected with the rack 1, and the lower wheel disc 6 and the upper wheel disc 7 are respectively connected with the lower swing arm 4 and the fixing arm 5 and used for coiling and caching the belt.
The tension spring 21 provides an initial tension force for the whole braking mechanism, the hollow rotating pin 22 can be pressed onto the pad 23 through the pull rod 24 to realize braking, one end of the belt 25 is connected with the pull rod 24, the other end of the belt is connected with the frame 1, and braking and releasing are realized through contact and separation with the belt pulley 26. As the belt is pulled out, the lower swing arm 4 is lifted from the lowest position to the buffer position, the brake of the brake mechanism is released and releases the belt disc, and the belt disc rotates and replenishes the upper and lower wheel discs with new belt.
The lower swing arm is also called a rotary swing arm, the lower swing arm performs reciprocating pendulum motion along the rotating shaft, and the lower swing arm is divided into a long arm end and a short arm end by the rotating shaft. In a free state (namely a drooping state), the tension spring penetrates through the hollow pin shaft arranged at the end of the short arm through the pull rod, and then tangential tension is applied to the belt disc through the belt to cause braking. When the belt is fed, the lower swing arm gradually swings upwards due to the pulling-out of the belt, and meanwhile, the hollow rotating pin at the end of the short arm descends proportionally. When the hollow rotating pin presses the pad on the pull rod, the belt starts to leave the belt wheel, the braking of the belt wheel is released, and the belt wheel starts to be rotated to replenish the belt for the belt. After the belt is fed, the lower swing arm slowly descends until the belt is engaged with the belt pulley again, and the belt pulley is braked; when the tape is taken up, the lower swing arm will continue to descend for a certain distance because part of the redundant tape returns to the tape tray frame, and the tape reel still keeps a braking state.
The invention works as follows: the baler starts working and the process of belt feeding starts. The belt is pulled out from the belt releasing device, the belt acts on the lower swing arm 4 through a belt wheel winding formed by the upper wheel disc and the lower wheel disc, the lower swing arm 4 starts to perform anticlockwise pendulum motion, and the hollow pin shaft 22 starts to swing downwards. When lower swing arm 4 is lifted to the buffer position, hollow rotating pin 22 starts to contact pad 23 and continuously presses pull rod 24, and belt 25 connected with pull rod 24 starts to be separated from pulley 26. At this point, the brake is released and the reel 3 begins to rotate, replenishing the pulley windings with new tape until the tape is dispensed. When the feeding is finished, the long arm end of the lower swing arm 4 slowly descends clockwise because the reel 3 is still in the releasing state, and when the lower swing arm 4 returns to the buffering position again, the tension spring 21 acts on the belt 25 again, so that the belt 25 starts to be engaged with the belt pulley 26. At the moment, the braking is recovered, the reel 3 stops rotating, the packaging machine starts to take up and package, at the moment, a part of the belt returns to the belt releasing device again, the lower swing arm 4 continues to descend to the lowest position, the whole action process is finished, and the above circulation is repeated.
In order to ensure efficient operation of the whole mechanism, the fixing arm 5 is connected with the frame through a fastening screw. Thereby assisting the frame to provide sufficient stability to the overall mechanism.
In order to improve the working efficiency of the mechanism, the pull rod is provided with a groove matched with the gasket. The mechanism can change the buffer length of the tape releasing system by adjusting the quantity of the gaskets, and realize the tape releasing requirements of different buffer quantities. The groove that sets up on the pull rod makes things convenient for the fixed of saucer on one hand, and on the other hand makes things convenient for operating personnel to observe.
The belt releasing mechanism of the structure presses down the gasket arranged at the upper end of the belt through the movable rotating pin arranged at the short shaft end of the lower swing arm, and the belt gradually breaks the inherent braking state of the system to release the belt. When the belt is taken up, the short shaft end is lifted up along with the descending of the lower swing arm, and the belt is contacted with the belt pulley again, so that the braking is realized. The buffer interval is the interval between the buffer when the lower swing arm is lifted to the hollow rotating pin from the initial state and starts to press the gasket, and the buffer requirements with different capacities are realized by adjusting the number of the gasket groups so as to change the time difference of pressing the gasket groups by the rotating pin. The invention does not need electrical equipment such as a motor, a sensor and the like, and is suitable for being applied to various complex environments; the buffer length of the whole mechanism is changed by adjusting the number and the height of the gaskets, so that the tape releasing requirements of different replacing quantities are met; the whole equipment has simple structure, convenient use and durability.
It should be understood by those skilled in the art that the protection scheme of the present invention is not limited to the above-mentioned embodiments, and various permutations, combinations and modifications can be made on the above-mentioned embodiments without departing from the spirit of the present invention, and the modifications are within the scope of the present invention.
