CS240779B1 - Device for drying cup cups after painting - Google Patents

Abstract

The device is in the form of a closed cabinet with a central supply and exhaust of warm air and with openings for inserting worktops from the factory. The internal space is divided by a system of chambers into a supply chamber, chambers with distribution plates, chambers for individual worktops and an outlet chamber with a drainage trough. Each chamber consists of side walls, the bases of which provide guidance for individual worktops, a distribution plate with attached nozzles, which forms the upper wall and base walls with stops, which form the lower wall.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for drying paint after painting the interior of articles, in particular match cups and complete matches for pistol and rifle cartridges.

Until now, a shelf cabinet that is heated by warm air is used to dry after painting the interior of the match cup or complete match. The matches or match cups are arranged in the worktops in a bottom-down position and at a distance from each other. The worktops are placed in a cabinet through which warm air flows. This gradually heats the worktops so that their contents are also heated, thereby drying the lacquer in the interior of the cups or complete matches. It is also known to use warm-heated shelves on which the filled worktops are gradually heated, thereby also drying the lacquer or similar substances applied to the interior of the products.

A disadvantage of said devices is the low drying intensity, which is slow. This affects work safety, as worktops accumulate on the drying operation and can be ignited and exploded if they are filled with complete matches. The low efficiency of these devices also results in higher thermal energy consumption, as the entire space and shelf are heated , including worktop. In both cases, the vapors contaminate the environment ·

The above-mentioned disadvantages are eliminated by the paint drying device after painting the interior of the products, in particular the match cups and the complete matches according to the invention.

The device consists of a closed box having several openings for inserting workbenches with products, a central inlet and outlet of hot air and a set of chambers in the interior. This inner space is divided into the inlet chamber, the chambers above the distribution plates, the chambers for individual worktops and the outlet chamber. The bottom wall of the outlet chamber passes into the downstream trough of the cups dropped from the worktops into the inner space of the cabinet. Each chamber for the individual worktops is formed in the lower wall by base plates which are provided with stops, side walls whose bases form the guiding of the individual worktop and the upper walls which are the distribution plates on which the nozzles are fixed.

With the device according to the invention, it is possible to intensively dry the applied lacquer layers, since the warm air is injected directly through the nozzles into the interior of the cups or other products. Unnecessarily heat the environment and worktop · The device works with great efficiency, which results in lower heat consumption, short drying time and increased work safety.

In the accompanying drawings, an exemplary embodiment of the device according to the invention is shown. FIG. 1 shows the device in front view, in partial section, FIG. 2 shows a partial section in side view with an inserted worktop with cups.

The device for drying the lacquer after painting the interior of the match cup has the shape of a housing 8 by a central hot air inlet 2a with a central hot air outlet 3. The openings 4 serve to insert worktops 6 filled with cups 6. The interior of the housing 1 is divided into a chamber inlet 7, on chambers 8 above the distribution plates 15 »on chambers 9 for individual worktops 5 and on the outlet chamber 10 with down-flow trough 11« Each chamber 9 consists of side walls 14, whose bases ensure guiding of individual worktops 5, plates 15 with fixed nozzles 16 forming the upper wall and base walls 12 with stops 13 forming the bottom wall;

The spray cup drying apparatus according to the invention operates in such a way that warm air is blown through the central inlet 2 into the inlet chamber 7, then into the chambers 8 from where it passes through the nozzles 16 directly into the interior of the cups. There are counterstops 18 and side wall bases 14 at the openings 4 through the openings 4. There are counterstops 18 and side wall bases 14 so that the nozzles 16 face directly against the individual cups 6 The warm air reflected from the interior of the cups 6 flows further through the space of the outlet chamber 10 and through the central outlet 3 goes into the outlet pipe.

This equipment can be used where it is necessary to quickly dry paint or other substances in small spaces, for products placed at a minimum distance from each other, eg * in the chemical or pharmaceutical industry ·
