Background
The bottle cap gasket is a machine for installing a gasket into a bottle cap, the gasket is made of various materials, the gasket is commonly made of rubber sheets, copper sheets or paper and is placed between two planes to be used for reinforcing sealing materials, the air tightness of the bottle cap gasket can be enhanced, the bottle cap and a bottle mouth are tightly attached, the gasket is generally made of soft materials and good in toughness, the gasket can be tightly attached to a circle of a bottle mouth after the bottle cap is covered, and the leakage-proof sealing effect is achieved. According to market research, the products in the bottle cap gasket market in China are hundreds of products, and the bottle cap gaskets of various types, specifications and types are full of the food packaging container market.
At present, with the rapid development of the packaging industry in China, the bottle cap gasket industry rises gradually. During production, the bottle cap gasket plugging device can plug the gasket into the inner bottom surface of the bottle cap completely, namely the gasket is in close contact with the inner bottom surface of the bottle cap. Generally, the gasket is manually pre-placed into the bottle cap, the gasket is not completely pressed into the inner bottom surface of the bottle cap at the moment, the gasket is horizontally placed on the conveying belt, then the gasket is conveyed to a gasket pressing point through the conveying belt, and then the gasket is completely pressed into the inner bottom surface of the bottle cap through a lower pressing head of the pressing device, so that the gasket can be tightly attached to the inner bottom surface of the bottle cap.
However, the manual pressing-in method has low production efficiency and high labor intensity, and because the speed on the production line is high, the gasket is often tilted when being put in, and the whole plane of the pressing head is in contact with the gasket and the pressing-in speed is high, so that the edge of the gasket is easily clamped on the edge of the outer side wall of the bottle cap in the pressing-in process, the gasket cannot be completely pressed in and damaged, and the defective rate of products is increased.
Disclosure of Invention
In order to make up for the defects of the prior art, the invention provides a bottle cap gasket adding machine which is mainly used for solving the problems of low production efficiency and high labor intensity caused by the fact that the existing bottle cap gasket industry mostly adopts a manual pressing method to realize pressing in of a gasket.
The technical scheme adopted by the invention for solving the technical problems is as follows: the invention relates to a bottle cap gasket adding machine which comprises a feeding slideway, a bottle cap transferring device, a discharging conveyor belt and a gasket pressing-in device, wherein the feeding slideway is arranged on the bottle cap transferring device;

through the arrangement of the blocking edge 11, the bottle cap 4 is prevented from sliding off from the feeding slideway 1 to cause damage; by arranging the inner side face of the second arc-shaped bulge 22 and the outer side face of the disc in an eccentric manner, the bottle cap 4 can move in a larger space at the feed inlet 23 and the discharge outlet 24, so that the bottle cap 4 can be fed or discharged smoothly, the bottle cap 4 can be pressed in at a pressing-in station, accurate positioning is realized, the situation that the standby gasket 81 and the bottle cap 4 are staggered due to the inclination of the bottle cap 4 is avoided, the problem that the standby gasket 81 cannot be pressed in completely to be damaged is avoided, and the defective rate is further reduced; through the arrangement of the piston cavity, the vent hole 33 and the spring 38, before the pressure head 95 moves downwards to the contact of the bottle cap 4, the buffer head 36 is extruded through the pressure plate 93, and then the buffer head 36 moves downwards by overcoming the elastic force of the spring 38 and the damping force at the vent hole 33, so that the buffer of the downward pressing of the pressure head 95 is realized, the damage of the bottle cap 4 caused by the over-quick downward pressing of the pressure head 95 is avoided, meanwhile, the gas exhausted by the vent hole 33 can be upwards sprayed out along the periphery of the bottle cap 4, and a standby gasket 81 which is not in time fallen into the bottle cap 4 and is lapped on the bottle cap 4 can be blown to be smoothly fallen into the bottle cap 4, so that the defective rate is further reduced; in addition, when the pressure head 95 moves up quickly after the standby gasket 81 is pressed in, the situation that the bottle cap 4 is turned over or separated from the semicircular carrying notch 32 is often caused due to instantaneous negative pressure in the bottle cap 4, and due to the arrangement of the vent hole 33, when the pressure head 95 moves up, the spring 38 resets the undetermined piston to move up, so that the vent hole 33 sucks air, the bottle cap 4 can be tightly sucked in the semicircular carrying notch 32, the situation that the bottle cap 4 is turned over or separated from the semicircular carrying notch 32 is avoided, and the bottle cap 4 pressed in the standby gasket 81 can be discharged smoothly; through the arrangement of the inclined plate 71, the buffer head 36 passing through the discharge port 24 can be extruded and moved downwards, and then the exhaust gas is exhausted through the exhaust hole 33 to push the bottle cap 4 to be separated from the semicircular carrying notch 32 as soon as possible, so that the bottle cap can be smoothly discharged, the situation that the bottle cap 4 clamped in the semicircular carrying notch 32 is damaged due to the collision between the bottle cap and the first arc-shaped bulge 21 is avoided, and the defective rate is reduced; meanwhile, the buffering head 36 passing through the feeding hole 23 is moved downwards in advance, when the buffering head 36 is separated from the inclined plate 71 and reset, a large suction force can be generated at the exhaust hole 33, so that the bottle cap 4 at the feeding hole 23 can smoothly enter the semicircular carrying notch 32, the problem that the subsequent gasket 81 for standby continues to be added and is wasted due to the fact that the bottle cap 4 cannot smoothly enter the semicircular carrying notch 32 is solved, the cost is saved, and meanwhile, the production efficiency is guaranteed.
