JPS5835469Y2 - Continuous manufacturing equipment for foamed latex products - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a simple and effective apparatus for quickly and accurately producing small foam products such as simple small foam latex having smooth sections.

In the manufacturing process of foamed latex products using the Dunlop method, the work must be carried out quickly and accurately within an extremely short period of time until the foamed compound gels, and it is necessary to prepare molds for continuous mass production. , casting and finishing operations require precision and efficiency.

The present invention has been devised to achieve this purpose, and a series of equipment for preparing molds, pouring, scraping, etc. is placed on the conveyor in a precise manner, and the work can be carried out extremely quickly and accurately. Furthermore, we propose an apparatus that can minimize raw material loss and prevent uneven quality.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

In Fig. 1, 1 is an endless belt conveyor whose speed is adjustable and has a feed pawl 2, 3 is a metal mold, and 4 is a built-in stack of many molds 3, which are moved up by gravity or a spring device from the bottom. This cartridge is designed to send one mold 3 onto a belt conveyor 1, and the mold 3 at the lower end of the cartridge is hooked on a feeding claw 2 and sequentially sent out in the advancing direction of the belt conveyor 1.

5 is a rubber roll, and 6 is an air nozzle that cleans the upper surface of the mold that has been sent out to clean rubber crumbs, dirt, and the like.

7 is an infrared heating tunnel for preheating, 8 is a casting tank,
9 is a foamed latex container, 10 is a flow rate adjustment balloon, 1
Reference numeral 1 denotes a scraper, which casts foamed latex into a mold 3 that has been cleaned and preheated in a heating tunnel 7 through a casting tank 8, and is cut into exaggerated shapes using a scraper 11.

That is, the foamed latex mixed in the foamed latex container 9 passes through the flow rate regulating valve 10, falls into the casting tank 8, is buffered, and is poured into the mold 3 under an appropriate pressure.
The mold recess is filled, and the exaggerated portion is cut and removed by passing through the scraper 11.

The tip of the scraper 11 has a moderate elasticity and smooths the upper surface of the mold, and also cuts off any thin exaggerations that flow at the edges of the mold.

Exaggerated cutting can be made more securely by using a mold that is made by press-working a metal plate and has a protruding edge 13 around the periphery of the mold recess 12, as shown in FIG.

FIG. 3A is a perspective view of the casting tank and scraper seen from the bottom, and the opening in FIG. 3 is a sectional view of the same.

The present invention has the above-mentioned configuration functions, and the molds are sent out one after another from the mold cartridge, cleaned and preheated, and the pre-casting preparation process is performed quickly, and the casting operation before gelation is performed quickly and accurately. It has great practical value in that it can reduce raw material loss, eliminate uneven quality, and mass-produce products with uniform quality while saving labor.
