Embodiment 1 this embodiment provides a rubbing mechanism, which includes a cam, a first transmission rod 4, a swing rod 6, a swing arm 8, and a second transmission rod 7. The cam is coaxially linked with the main shaft 2 of the cutting equipment and is used for obtaining the rotating motion synchronous with the rotation of the main shaft 2 from the main shaft 2 and converting the rotating motion into a periodical jacking motion. The cam is groove cam 3, and top 401 of first drive link 4 is equipped with the cam groove roll cooperation of rolling element and groove cam 3: the groove cam 3 is disc-shaped, the center of which is fixed on the main shaft 2, and the main shaft of the middle ring of which is provided with a circle of cam grooves 310. The cam groove 310 is an annular groove opened on one side surface of the groove cam 3, and a convex part 311 is arranged on one side wall of the annular groove far away from the center. The top end 401 of the first transmission rod 4 is vertically provided with a roller 410, and the roller 410 is clamped in the cam groove 310 and is in contact fit with the cam groove. The first transmission rod 4 is used for converting the jacking action into linear motion.
The bottom end 402 of the first transmission rod 4 is in transmission fit with the swinging rod 6: one end of the swing lever 6 is hinged and rotatably fixed to the rack side wall 101 and is a hinged end 602, and the other end of the swing lever 6 is a free end 603 which swings freely with the hinged end 602 as a center. The middle part of the swing lever 6 is provided with a through groove 601, and after the bottom end 402 of the first transmission rod 4 passes through the through groove 601 from top to bottom, a limit bulge 420 is matched to prevent the bottom end of the first transmission rod 4 from exiting from the through groove 601. Thus, the bottom end of the first transmission lever 4 is linked with the middle portion of the swing lever 6, and the linear motion is transmitted to the swing lever 6.
The free end 603 of the swing rod 6 is hinged with the upper hinge joint 701 at the top end of the second transmission rod 7, the swing arm 8 also swings on one side, i.e. one end of the swing arm 8 is fixedly connected with the rotating shaft of the rubbing roller 9 and is a fixed end 801, and the other end of the swing arm 8 is hinged with the lower hinge joint 702 at the bottom end of the second transmission rod 7 and swings. The free end 603 of the swing lever 6 and the swing end 802 of the swing arm 8 are connected by the second transmission lever 7, so that the swing lever 6 and the swing arm 8 swing together.
In this embodiment, the aperture of the through groove 601 is adapted to the lateral displacement of the first transmission rod 4 relative to the swing rod 6 in the direction perpendicular to the linear motion, that is, the cross section of the through groove 601 is a non-circular shape such as an oval or a oval, which is suitable for the displacement of the swing rod 6 in the horizontal direction when the first transmission rod 4 is restricted to move back and forth only along the jacking direction (the drawing of this embodiment shows a vertical motion).
The swing rod 6 of the present embodiment adopts a single-side swing structure, and has the advantages of high controllability and stability, and particularly, in the present embodiment, on the premise that the force transmission path of the cam, the first transmission rod 4, the swing rod 6, the second transmission rod 7, and the swing arm 8 is a vertical path from top to bottom, the free end 603 can naturally swing down under the action of gravity, and the movable rod naturally droops and is kept stable under the action of gravity. The other end of the first transmission rod 4 is linked with the swinging rod 6.
The working principle of the twisting mechanism of the embodiment is as follows:
after the cam obtains a rotation motion from the main shaft 2 of the cutting device, the cam is matched with the swing rod 6 through the first transmission rod 4 and the swing rod 6 to be converted into an upward or downward swing at the free end 603 of the swing rod 6, then the swing end 802 of the swing arm 8 is driven to swing through the second transmission rod 7, and as the fixed end 801 of the swing arm 8 is coaxially fixed with the rubbing roller 9, when the swing end 802 of the swing arm 8 swings, the swing end 802 swings to be influenced. The fixed end 801 of the oscillating arm 8 will bring the rotation shaft of the rubbing roller 9 to rotate a certain angle. The structure can further enlarge the twisting range by means of the matching relationship between the second transmission rod 7 and the swinging arm 8 and the outward expansion or elongation of the second transmission rod 7 in the left direction in the figure 3 and then matching with the swinging arm 8, thereby improving the twisting effect.
In addition to the above-described embodiments, the present embodiment can further include a third transmission rod 10 disposed at the swing end 802 of the swing arm 8, wherein the third transmission rod 10 is disposed symmetrically with respect to the second transmission rod 7, and the third transmission rod 10 is preferably fixedly connected to the second transmission rod 7. The third transmission rod 10 has two functions: firstly, the pendulum bob is used as a pendulum bob matched and corresponding to the second transmission rod 7, the lower swinging force of the swinging end 802 of the swinging arm 8 is enhanced, and the twisting effect is ensured; and the second mechanism is used for transmitting the swing to other mechanisms so that the other mechanisms can realize the action or partial action of the mechanisms by means of the action.
Example 2 this example differs from example 1 in that: the structure of the swing rod 6 in this embodiment is different from that in embodiment 1, and the middle of the swing rod 6 provided in this embodiment is provided with a hinge structure, the hinge structure is a hinge seat 12 protruding from the upward side surface of the swing rod 6, the bottom end of the first transmission rod 4 is hinged to the hinge seat 12, and the free end 603 of the swing rod 6 is driven to move up and down through the matching relationship with the hinge seat 12.
In order to adapt to the structure of the swing rod 6 swinging on one side, the hinge hole of the hinge base 12 in this embodiment is a non-circular hole such as an oval or a waist circle, so as to adapt to the displacement of the swing rod 6 in the horizontal direction in the process of matching the first transmission rod 4 with the swing rod 6. Of course, the above structure is based on the premise that the first transmission rod 4 is limited by the limit seat 5 to only move vertically.
Example 3 this embodiment differs from the above embodiments in that: in this embodiment, the swing lever 6 has a double-side swing structure, which is as follows: the middle part of the swing lever 6 is rotatably fixed on the rack side wall 101 through a pin, and both ends of the swing lever 6 are free ends 603 (for distinguishing from the free ends 603 in embodiment 1, the free ends 603 are called as a first free end 603 and a second free end 603). The first free end 603 of the swing rod 6 is in abutting fit with the bottom end of the first transmission rod 4, and the second free end 603 is connected with the top end of the second transmission link.
The structure is a bilateral swing structure, and compared with unilateral swing, the structure has higher installation difficulty and inferior stability and controllability to the bilateral swing structure.
Example 4 this example differs from the above example in that: the cam is a cam sleeve 11, in the embodiment, the top end of the first transmission rod 4 is hinged to the bottom of the outer ring of the cam sleeve 11, and the bottom end of the first transmission rod 4 is hinged to one end of the swinging rod 6. In order to facilitate the direct engagement between the first transmission rod 4 and the swing rod 6, the movement of the first transmission rod 4 in the horizontal direction is not limited in this embodiment, that is, the structure of the limiting seat 5 is eliminated, and the limitation on the first transmission rod 4 is eliminated in this embodiment.
Compared with the limitation of the movement of the first transmission rod 4 provided in the embodiments 1 to 3, the structure of the present embodiment is simpler, but the structural stability is poorer, and the cam sleeve 11 is more costly and the connection requirement for the first transmission rod 4 is higher.
In this embodiment, the main shaft 2 is preferably disposed above the rubbing roller 9 and parallel to the rubbing roller 9. To facilitate direct rubbing of the adhesive portion at the cutting site, the rubbing roller 9 is preferably disposed adjacent to the cutting position of the cutter unit 14.
As shown in fig. 5, in this embodiment, two sides of the frame 1 are provided with frame side walls 101, and the rubbing mechanism is installed outside one side wall of the frame 1.
As mentioned above, the rubbing mechanism includes the cam, the first transmission rod 4, the swing rod 6, the second transmission rod 7 and the swing arm 8, and the cam is fixedly sleeved on the main shaft 2 and coaxially connected and synchronously rotated. The protrusion of the swing wall on the rack side wall 101 and the limiting seat 5 of the rack side wall 101, the first transmission rod 4 is slidably arranged in the limiting seat 5 through a linear bearing 510.
