DETAILED DESCRIPTION

[0020] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0021] The utility model proposes an automatic capping device, comprising a conveying mechanism 1 for conveying bottle bodies 4, the conveying mechanism 1 is a conveyor belt, the conveying mechanism 1 is used to convey the bottle bodies 4, two guide plates 2 are installed on the conveying mechanism 1, the two guide plates 2 are equidistantly arranged, and the two guide plates 2 are symmetrically arranged about the conveyor belt, and the bottle bodies 4 are conveyed between the two guide plates 2.

[0022] A cap feeding mechanism 3 is arranged above the bottle body 4, and the cap feeding mechanism 3 is supported on the guide plate 2 through a support frame. The cap feeding mechanism 3 includes a horizontal portion 31, and the horizontal portion 31 is a conveying trough. One end of the horizontal portion 31 is connected to the cap feeding machine, and the other end of the horizontal portion 31 is integrally connected with an inclined portion 32, which is a square tube-shaped channel. The inclined portion 32 and the horizontal portion 31 are set at the same angle, and the high end of the inclined portion 32 is connected to the horizontal portion 31. The width of the horizontal portion 31 and the inclined portion 32 is set to be the same as the diameter of the bottle cap 5.

[0023] Clamping claws 321 are rotatably connected to both outer walls of the inclined portion 32 , one end of the clamping claws 321 is rotatably connected to the inclined portion 32 , and the other end of the clamping claws 321 is arranged in an arc shape. The spacing between one end of the arc of the two claws 321 is smaller than the diameter of the bottle cap 5, so as to limit the inner bottle cap 5 of the inclined portion 32. The middle part of the claw 321 is fixedly connected to the limiting cylinder 3211, and the limiting cylinder 3211 is arranged perpendicular to the claw 321. One end of the limiting cylinder 3211 close to the inclined portion 32 is open, and the other end of the limiting cylinder 3211 is closed. A limiting column 323 is also arranged between the inclined portion 32 and the claw 321, one end of the limiting column 323 is welded to the inclined portion 32, and the other end of the limiting column 323 is extended into the limiting cylinder 3211 and is slidably connected to the limiting cylinder 3211. A short spring 3231 is also sleeved on the limiting column 323, one end of the short spring 3231 is fixedly connected to the inclined portion 32, and the other end of the short spring 3231 is fixedly connected to the closed end of the limiting cylinder 3211.

[0024] When the bottle body 4 contacts the bottle cap 5, the impact force of the bottle body 4 can be transmitted to the bottle cap 5, thereby driving the bottle cap 5 to move with the bottle body 4. When the bottle cap 5 moves, the two claws 321 can be opened, thereby causing the bottle cap 5 to fall from the inclined portion 32 to the bottle mouth of the bottle body 4. After the bottle cap 5 falls out, the claws 321 will automatically reset under the elastic force of the short spring 3231, thereby limiting the next bottle cap 5.

[0025] The upper surface of the inclined portion 32 is rotatably connected with a pressing plate 322, and a pressing groove 3221 is welded at the bottom end of the pressing plate 322. The notch of the pressing groove 3221 is set downward, and the width of the pressing groove 3221 is also set to be the same as the diameter of the bottle cap 5. The pressing groove 3221 can limit the bottle cap 5 after the bottle cap 5 falls out of the inclined portion 32, further avoiding the problem that the bottle cap 5 will fall due to the impact force of the bottle body 4.

[0026] The pressing groove 3221 is inclined, and the high end of the pressing groove 3221 is welded to the pressing plate 322, so that when the bottle cap 5 falls and moves with the bottle body 4, the pressing groove 3221 can squeeze the bottle cap 5, so that the bottle cap 5 and the bottle body 4 are buckled more firmly, avoiding the problem of the bottle cap 5 falling off due to loose buckling with the bottle body 4 during the subsequent transportation to the capping machine.

[0027] Two baffles 21 are rotatably connected to the guide plate 2. The two baffles 21 are respectively arranged on the two guide plates 2, and the two baffles 21 are symmetrically arranged about the conveying mechanism 1. The baffles 21 are arranged below the pressing groove 3221. A limiting block 22 is also welded on the guide plate 2. The limiting block 22 is arranged corresponding to the baffle 21. The limiting block 22 is arranged on the side of the baffle 21 away from the lower end of the pressing groove 3221, that is, the rotation of the baffle 21 is limited. The end of the baffle 21 close to the bottle body 4 is arranged in a wedge shape, and the inclined surface of the wedge shape is arranged on the side away from the lower end of the pressing groove 3221. By arranging the baffle 21, the phenomenon of reverse movement of the bottle body 4 can be avoided, that is, the conveyance of the bottle body 4 can be avoided from being affected by the squeezing of the pressing groove 3221.

[0028] A screw 3222 is passed through the pressure plate 322, one end of the screw 3222 is welded to the upper surface of the inclined portion 32, a long spring 32221 is sleeved on the screw 3222, a nut is threadedly connected to the screw 3222, one end of the long spring 32221 is abutted against the upper surface of the pressure plate 322, and the other end of the long spring 32221 is abutted against the nut, and by rotating the nut, the compression length of the long spring 32221 can be changed, thereby adjusting the preload force of the long spring 32221, and further adjusting the pressing force of the pressing groove 3221 on the bottle cap 5.

[0029] Working process: First, when the bottle body 4 contacts the bottle cap 5, the impact force generated during the transmission of the bottle body 4 can drive the bottle cap 5 to move accordingly, so that the bottle cap 5 opens the two claws 321, and the bottle cap 5 falls from the inclined portion 32 to the bottle mouth of the bottle body 4. At this time, the top of the bottle cap 5 also moves into the pressing groove 3221, and the bottle cap 5 can be prevented from falling under the action of the limiting guide of the pressing groove 3221.

[0030] Secondly, the bottle body 4 drives the bottle cap 5 to continue to be transported along the direction of the pressing groove 3221. When the bottle body 4 contacts the wedge-shaped beveled edge of the blocking bar 21, the two blocking bars 21 can be pushed apart and continue to move. At the same time, due to the inclined setting of the pressing groove 3221, the squeezing pressure of the pressing groove 3221 on the bottle cap 5 will gradually increase until the bottle body 4 drives the bottle cap 5 to move out of the pressing groove 3221.

[0031] Finally, the bottle cap 5 and the bottle body 4 that have been moved out of the pressing groove 3221 are securely fastened together and continue to move toward the capping machine.

[0032] In summary, the utility model can limit the movement of the bottle cap 5 after the bottle body 4 impacts the bottle cap 5 from the cap feeding path by setting the pressing groove 3221, so as to prevent the bottle cap 5 from shaking and detaching from the bottle body 4 due to the impact force, and further prevent the bottle cap 5 from falling off the bottle body 4 during the capping process. By setting the pressing groove 3221 obliquely, the bottle cap 5 can be pressed tightly, and further, the bottle cap 5 can be buckled more firmly with the bottle body 4, so as to prevent the bottle cap 5 from falling during the transportation to the capping machine.
