Daily Maintenance for Better Use of Walnut Shortbread Machine

Feb. 10, 2026

To make better use of the multi-functional walnut shortbread machine, daily maintenance is very important!

The multi-functional walnut shortbread machine is composed of two major parts: the mold forming system and the tray chain conveying system, which are driven by speed-regulating motors respectively, and the production speed can be adjusted. The forming system is equipped with a feeding roller, a mold roller and a rubber roller. The prepared dough is put into the hopper, and is formed into walnut shortbread blanks through the feeding and extrusion of the feeding roller and the mold roller. Then, the blanks are conveyed to the baking tray by the canvas belt dragged by the rubber roller. The tray chain is driven by a speed-regulating motor, and the spacing of the walnut shortbread blanks on the flat tray can be determined according to production needs. In addition, the machine is also equipped with several adjustment mechanisms in its structure: the canvas tension and deviation adjustment mechanism, the left-right and up-down adjustment mechanism of the dough dividing knife, the canvas material sticking cleaning and scraping mechanism, the feeding gap adjustment mechanism, etc.

We need to carry out maintenance and upkeep according to the operating characteristics of this equipment. After use, cleaning may be necessary to avoid wear and tear on the walnut shortbread forming machine caused by food residues, which could lead to equipment shutdown.

The following are the methods to extend the lifespan of the multi-functional walnut shortbread machine:

Electrical control part

Traditional injection machines use contact relays to switch various actions. They often malfunction due to loose contact screws and contact aging. Usually, new products should be replaced after one million uses to ensure the stability of the electrical control. In particular, environmental factors such as dust adhesion and humid air can also affect the machine's operation. Modern walnut shortbread forming machines adopt contactless integrated circuits, greatly reducing the connection of wires, significantly improving the problems caused by wires, and enhancing stability. It should be noted that before use, all parts must be returned to their original positions. If not, they need to be adjusted to the origin.

Mechanical part

The mechanical part should be regularly maintained and lubricated to reduce the friction coefficient and wear. The nuts and locking screws on the head plate should be regularly inspected to prevent the gooseneck from breaking due to uneven stress. The mold thickness adjustment mechanism should be regularly inspected for any deviation or looseness of the large gear or chain on the drive shaft. Check whether the pressure plate screws on the gear are loose and whether there is sufficient lubricating grease.

Hydraulic part

In terms of the hydraulic system, attention should be paid to the cleanliness of the hydraulic oil to maintain its quality. Hydraulic oil with good stability and high quality should be used. In addition to regular replacement, the working temperature should be properly controlled below 50°C to avoid affecting the stability of the hydraulic action due to deterioration.

Maintenance work

Try to stand on the plastic blanket when performing maintenance work. Never perform maintenance on the walnut shortbread forming machine on a flooded floor or in a very humid environment. When maintaining the walnut shortbread forming machine, safety gloves, goggles, and long - sleeved work clothes must be worn to prevent parts of the body from being injured by high temperatures or burned by the surface of high - temperature components.
