Feed and discharge mechanism for plastic bottle cap extruding machine

Abstract

The invention discloses a feed and discharge mechanism for plastic bottle cap extruding machine, which comprises a spindle mounted in a spindle seat, a rotating wheel mounted outside the spindle, a gas circuit distributor mounted below the spindle as well as a feed disc and a discharge flying disc mounted on the spindle. The feed and discharge mechanism for plastic bottle cap extruding machine ischaracterized in that: the gas circuit distributor comprises an intake disc and an exhaust disc; an intake hole is arranged in the intake disc and is connected with the gas source of a gas compressorby an intake pipe; an exhaust hole is arranged in the exhaust disc and is connected with a gas pipe; a hollow cavity of the gas pipe in which the spindle is inserted is connected with a gas conveyingchannel of the feed disc; the gas conveying channel of the feed disc is provided with a pneumatic port; a material cutter holder and a material cutter are mounted below the feed disc aiming at the pneumatic port; a plunger is mounted in the pneumatic port; the plunger is provided with a return spring; a suction disc is arranged below the discharge flying disc; a division plate is arranged betweenthe suction disc and the feed disc; a vacuum hood is arranged on the suction disc; a vacuum joint is mounted on the vacuum hood; a vacuum pipe is connected with a vacuum pump by the vacuum joint; thesuction disc is provided with a vacuum channel and a vacuum suction hole; a vacuum gas chamber in the vacuum hood is communicated with the vacuum channel; and the edge of the discharge flying disc isprovided with a poking tooth and a bottle cap console.

Description

technical field [0001] The invention relates to a plastic bottle cap extruder feeding and forming bottle cap sending mechanism, belonging to the field of plastic machinery. Background technique [0002] Multi-station processing equipment for bottle caps such as mineral water bottles, oil bottles and medicine bottles, including plastic extruder and capping machine. It is sent to the capping machine mold, and when the capping machine presses the hot-melted plastic into bottle caps, an intermediate discharge mechanism is required to take out the formed bottle caps. Therefore, the plastic bottle cap extrusion equipment needs to be equipped with feeding and discharging mechanisms. , or the middle manipulator, which feeds the material on the one hand and takes out the cap on the other hand. In the prior art, plastic bottle cap extruders have many types of mechanisms for feeding and discharging materials. The rotating disc system can be used, one of which is a feeding disc. The fe...

AI Technical Summary

Problems solved by technology

In the prior art, there are many types of mechanisms for plastic bottle cap extruders to complete the feeding and discharging of materials, which can be achieved through a rotating disc system, one of which is a feeding disc, which drives the knife, and the knife extrudes the extruder. The hot-melt plastic is sent to the mold cavity of the capping machine; the other is the discharging disc, which has teeth on the edge of the discharging disc, which take the formed caps out of the mold of the capping machine and send them to the collection system, such as a collection box Or conveyor belts, but this type of existing technology has the following disadvantages: because the speed of the capping machine is very fast, hundreds of bottle caps must be processed per minute, and the feeding plate is only sent to the mold cavity with the hot melt plastic by the knife The blanking (feeding) is incomplete, the position is not accurate, the speed is not fast enough, the reliability is poor, and the scrap rate is high, which affects the production efficiency and processing quality of plastic bottle caps.

On the other hand, due to the fast speed of the capping machine, the speed of the flying disc must also rotate rapidly, so the centrifugal force of the flying disc is very large. Flying and jumping, almost like an object exploding, resulting in damage to the bottle cap collision, and difficult collection, which affects the quality of the molded product
