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 to 7, the present invention provides a technical solution:

example (b):

as shown in fig. 1-7, a cap grabbing mechanism of a cap screwing machine comprises a tool 1, three pneumatic grippers 2 and a flexible buffer ring 3, wherein the tool 1 is of a cylindrical structure, the three pneumatic grippers 2 are respectively connected with the tool 1 in a sliding manner, and the three pneumatic grippers 2 are uniformly distributed along the circumferential direction of the tool 1;

the inner sides of the pneumatic grippers 2 are of arc-shaped structures, the inner sides of the pneumatic grippers 2 are arranged on the same circumference, a boss 4 and a mounting groove 5 are arranged at one end, close to the tool 1, of the inner side of each pneumatic gripper 2, and the boss 4 is located between the mounting groove 5 and the tool 1;

the buffer ring 3 comprises a rotary cover part 6 and a limiting part 7, the rotary cover part 6 is of a circular column structure, the limiting part 7 is of an annular plate structure, and the width of the limiting part 7 is the same as that of the boss 4; spacing portion 7 through mounting groove 5 with pneumatic 2 of grabbing is connected, spiral cover portion 6 sets up in one side that frock 1 was kept away from in spacing portion 7.

Wherein, the limiting part 7 is contacted with the top of the bottle cap 15 to protect the top of the bottle cap 15. Wherein the tool 1 is provided with an air cylinder for driving the pneumatic gripper 2, and the working principle and the air path principle of the pneumatic gripper 2 are the prior art which can be specifically referred to but not limited to the patent with the publication number of cn201620457224.x, and are not described herein.

The rotary cover part 6 and the limiting part 7 are of an integrated structure.

The buffer ring 3 is made of flexible silica gel and rubber materials.

The working principle is as follows: this grab and cover the spiral cover machine that the mechanism matches among the prior art and uses, and spiral cover machine structure and principle do not do the repeated description. The cushion ring 3 is arranged between the three pneumatic grippers 2. Then the bottle cap 15 is in place and coaxial with the buffer ring 3, and at the moment, the whole tool 1 descends to the top of the bottle cap 15 and is abutted against the limiting part 7. The pneumatic grippers 2 then move towards each other, so that the diameters of the circles on which the three pneumatic grippers 2 are located are reduced, and the cap screwing part 6 is pressed on the bottle cap 15. Meanwhile, the motor of the cap screwing machine drives the cap grabbing mechanism to integrally rotate, so that the bottle cap 15 is screwed tightly.

The utility model discloses a set up buffer ring 3 and can avoid pneumatics to grab 2 direct contact bottle lid 15, avoid pneumatics to grab 2 power too big and wearing and tearing bottle lid 15, make the product scrap. The buffering ring 3 can also reduce the preset torque force, the fluctuation range of the preset torque force is small, and the cover twisting and grabbing effects are better.

Further, as shown in fig. 2-7, a T-shaped groove 8 is formed in the tool 1, a sliding block 9 is slidably connected in the T-shaped groove 8, and the pneumatic gripper 2 is connected with the sliding block 9.
