Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution:

the embodiment is as follows:

as shown in fig. 1-3, a rotary pressure head for a notching and taping machine comprises a frame 1, a gear ring 2, a rotary ring disc 3, a notching tool 4, a central rotary column 5 and a plurality of rotary driving components 6;

the height of the gear ring 2 is gradually increased from one side of the rack 1 to the other side, and the gear ring 2 is fixed at the top of the rack 1;

the top of the central rotating column 5 is rotatably connected with the top of the rack 1, the bottom of the central rotating column 5 is connected with an output shaft of a motor 7, and a guide fixing disc 8 coaxial with the central rotating column 5 is fixed outside the central rotating column 5;

the plurality of rotary driving assemblies 6 are in sliding connection with the guide fixing disc 8; the rotary driving assembly 6 comprises a rotary pressing shaft 9, a connecting rod 10, a pressing head 11 and a return spring 12, the rotary pressing shaft 9 and the connecting rod 10 are respectively connected with the guide fixing disc 8 in a sliding manner, the top of the connecting rod 10 is tightly pressed against the bottom surface of the gear ring 2, the connecting rod 10 is connected with the rotary pressing shaft 9 through a connecting plate 13, the pressing head 11 is arranged at the bottom of the rotary pressing shaft 9, teeth matched with the gear ring 2 are arranged at the top of the rotary pressing shaft 9, the return spring 12 is sleeved outside the connecting rod 10, and the return spring 12 is arranged between the guide fixing disc 8 and the connecting plate 13;

the rotating ring disc 3 is coaxially arranged outside the central rotating column 5, the rotating ring disc 3 is located below the guide fixing disc 8, the notch tools 4 are multiple, and the notch tools 4 are respectively coaxially arranged with the pressing heads 11 of the rotating driving assemblies 6.

Wherein, 1, even board 13 is fixed with connecting rod 10, rotates through the bearing between even board 13 and the rotatory last item 9 and is connected, the outer lane and even board 13 fixed connection of bearing, the inner circle and the rotatory last item 9 fixed connection of bearing. The connecting plate 13 is connected with the rotary pressing shaft 9 through a bearing, so that the synchronous ascending and descending of the rotary pressing shaft 9 along with the connecting plate 13 can be ensured, and the rotation of the rotary pressing shaft 9 is not interfered by the connecting plate 13. 2. A notching cutter 15 is fixed on the rack 1, the notching cutter 15 is an arc cutter, the notching cutter 15 is not coaxial with the central rotating column 5, and the notching cutter is arranged so that notching can be completed when the bottle cap rotates along with the rotating ring disc 3. 3. n is a positive integer, and is selected according to actual processing requirements, such as 6, 8, 10 and 12.

The plurality of rotary driving assemblies 6 are uniformly arranged along the circumferential direction of the guide fixing disc 8.

The motor 7 is a stepping motor.

The working principle is as follows: the bottle cap is placed on the notching tool 4 and supported by the notching tool 4. When the central rotary column 5 rotates, the rotary ring disc 3 and the guide fixed disc 8 are driven to synchronously move. When the guide fixing disc 8 rotates, the rotary driving assembly 6 connected with the guide fixing disc moves synchronously. When the rotation driving component 6 moves, the top of the rotation pressing shaft 9 is meshed with the gear ring 2 through the teeth, so that the rotation pressing shaft 9 rotates along with the guide fixing disc 8 and also does self-rotation motion (namely the rotation pressing shaft 9 rotates around the axis of the rotation pressing shaft) under the action of the gear ring 2 and the teeth, and the rotation pressing shaft 9 drives the pressing head 11 to synchronously self-rotate while self-rotating.

And because the height of ring gear 2 is crescent gradually, therefore connecting rod 10 can be along vertical motion when ring gear 2 bottom motion, and connecting rod 10 drives rotatory pressure axle 9 through even board 13 effect and is vertical motion in step during vertical motion, and then realizes compressing head 11 towards the bottle lid motion.

Initially, the pressing head 11 is located above the bottle cap, and as the pressing head 11 rotates along with the guide fixing disc 8, the pressing head 11 moves towards the bottle cap and presses the bottle cap outside. When the pressing head 11 is pressed outside the bottle cap, the bottle cap is driven to rotate on the notch tool 4 due to self-rotation of the pressing head 11. The cap is automatically notched when it passes the notching tool 15.

The bottle lid incision is ended, along with the continuation rotation of direction fixed disk 8, ring gear 2 highly diminishes gradually, and connecting rod 10 resets under the effect of reset spring 12 this moment, drives rotatory pressure axle 9 and resets, and the synchronous reset of clamp head 11 leaves the bottle lid that has notched. At this time, the process of removing the bottle cap is completed.

Because the height of the gear ring 2 is of a gradual change structure, the situation that the connecting rod 10 suddenly moves downwards or upwards in the using process can not occur, the running stability of the whole machine is ensured, and the reduction of the vibration generated in the vertical motion process of the connecting rod 10 is facilitated.

The utility model discloses a ring gear 2 and rotation drive assembly 6's setting can realize the rotation and the autogyration of bottle lid through same motor 7, has avoided the use of a plurality of motors 7, and because the stability of bottle lid when the incision can be guaranteed in the setting of clamping head 11, avoids the incision dislocation.

Further, as shown in fig. 1, a rolling column 14 is rotatably connected to the top of the connecting rod 10, and the rolling column 14 abuts against the bottom surface of the gear ring 2. The rolling friction between the rolling column 14 and the ground of the gear ring 2 can reduce the energy consumption and the abrasion of the connecting rod 10 in the rotating process along with the guide fixing disc 8.

Further, a rubber layer is arranged inside the pressing head 11. The friction between multiplicable clamp head of rubber layer and the bottle lid that sets up avoids the clamp head to drive the bottle lid and skids when rotating, and the rubber layer still can provide the protection to the bottle lid simultaneously, avoids clamp head and bottle lid direct contact to make the bottle lid surface produce wearing and tearing.

The foregoing is illustrative of the preferred embodiments of the present invention, and it is to be understood that the invention is not limited to the precise forms disclosed herein, and that various other combinations, modifications, and environments may be resorted to, falling within the scope of the invention as defined by the appended claims. But that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the invention, which is to be limited only by the claims appended hereto.
