The Cross Conveyor is used for cross conveying glass tableware to an annealing lehr. The machine adopts the balance point-wheel step-less reducer and the tooth chain. It has the advantages of wide speed range, smooth production through no skidding, long life span, a stable structure and ease of maintenance and repair.

• Belt speed: 1.5~5m/min

• Stepless inverter speed control

• 4 pcs of belt fire heat-gun

• Power: 1KW

With more than 30 Years experience in manufacturing conveyor belts, we are able to design belts to reduce friction and spiral "locking".

Our belts are manufactured with precision and accuracy to ensure smooth and stable feeding of glassware. High Quality Stainless Steels were used to prevent marking and staining.

Lehr Belt material available: AISI 321, 302, 304, 304L, 316, 316L, 310, 310S, 314, 410 & 2080

Conveyor Belt

The Push Stacker is used for pushing glass wares into the annealing lehr. The machine features a curve-type pushing mechanism with speed regulation by an invertor. The number of glasswares being pushed per cycle can be controlled by a digital counter.

Our annealing and decorating lehrs are suitable for the heat treatment of glass containers and tableware after forming. The purpose of the annealing lehr is to relieve the stress in the glass containers after forming. The purpose of the decorating lehr is to allow chemical bonding of the print onto the glass containers, after printing.

​

In order to achieve temperature homogeneity in the lehrs, they are designed with the following specifications:

• Fans: All heating and cooling zones are equipped with air circulating fans.

• Burners: Venturi-type On/Offf burners are used to ensure even heating and temperature control.

• Inner Wall: Heat resistant stainless steel (AISI 409L or AISI 304) is used for all inner walls of each zone.

• Belt Material: 1Cr13 or AISI 304 stainless steel

• Thermocouple: Stainless Steel Sheathed Ni Cr type K thermocouple is installed in each zone

• All the temperature control meters on the control panel are imported from Japan, model TM225 and Belt speed is controlled by invertor from Fuji, Japan. 

Annealing/Decorating Lehr

Our Belt-Type tempering lehr is suitable for the tempering of glass plate and bowl. The design of
preheating zone and heating zone are similar to that of annealing lehr with circulating fan. After the
heating zone, all the glass articles require immediate and even cooling-down in order to toughen the
glass plate. The cooling ducts with adjustable pressure cooling air are provided. Each cooling duct is
connected through air pipes to a rectangle box which has many small air tubes. The rectangle air tubes
are positioned above and below the glass article in order to cool down both sides of the glass article
evenly.

Tempering Lehr

Our tempering lehrs are used for the heat treatement of glass tableware in order to increase their mechanical resistance towards impact and thermal resistance from high temperature change. This helps to prevent cracking or shattering of glass tableware if they are dropped onto the ground, or from shattering if they are put in high temperature, e.g. microwave oven  

Belt-Type Tempering Lehr

Our Spindle-Type tempering lehr is suitable for the tempering of glass tumbler
and bowl. This lehr consists of 3 zones as follow:
1. Preheating Zone. With 4m conveyor and 5 sets of burner firing, where the rotating glassware are preheated to high temperature.
2. Heating Zone. Through 15m heating tunnel constructed with refractory and 16 burners, the glassware is heated up to about 680°C evenly.

3. Tempering Zone. 5 Sets of high pressure air cooling chamber are designed to quench the
glassware from the top, bottom and both sides evenly.

Spindle-Type Tempering Lehr

The Mould Pre-heating Oven is used for heating up the moulds before they can be put onto the machine for glass production. Moulds can be pre-heated by natural gas firing or by electrical-heating.

Mould Pre-heating Oven

Various types of blowers were used in the glass plants.

JCL Blowers includes:

• Furnace cooling blowers

• Furnace throat cooling blower

• Furnace combustion air blower

• IS machine mould cooling blower

• IS machine air blower

Blowers

Air Reversal System is used for reversing air-flow through the regenerator of the glass furnace. In addition to double deck air reversal unit, JCL also manufactures butterfly valve and pressure transmitter as part of the air reversal system.

Air Reversal System

The glass cullet scraper conveyor is used for returning the glass cullet to the batch plant for glass production.

Glass Cullet Scraper Conveyor

The glass cullet Crusher is used for crushing glass into cullet, which is then re-used as a raw material in glass melting. We provides two types of glass cullet: hammer-type and jaw-type crushers.
