Technical Field

The invention relates to the technical field of food processing machinery, in particular to equipment for stretching soft dough or sugar balls in the processing and manufacturing processes of wheaten food, sesame sugar and the like.

Background

Traditional sesame candy, stewed noodles and stretched noodles are made by pulling a sugar mass or a dough manually by a worker, the workload is large, the efficiency is low, the labor cost is high, some manufacturers develop extrusion equipment with a simple process to try to replace the manual work, but the mouth feel of the extruded cooked wheaten noodles is far from that of the stretched cooked wheaten noodles, especially the traditional sesame candy is made by repeatedly pulling the traditional sesame candy by the worker, so that a large amount of air enters the sugar mass to form a plurality of cavities, the crisp mouth feel of the produced sesame candy is good, the material cost is low, but the mechanical extrusion mode is used for replacing the manual pulling, the produced sesame candy cannot form a plurality of cavities, the mouth feel is hard, and the material cost is greatly increased. Therefore, the device for stretching the dough or the sugar mass, which has a simple structure, low cost and high efficiency, is designed for manufacturing stewed noodles, stretched noodles and sesame sugar.

Detailed Description

The invention will be further described with reference to the drawings and specific embodiments, which are illustrative of the invention and are not to be construed as limiting the invention.

The soft material stretching equipment comprises a main body mounting frame 1, a feeding conveyor belt 2 and a discharging conveyor belt 3, and the rest part consists of an upper mechanical module and a lower mechanical module which are the same, wherein the left driving wheel group 7 and the right driving wheel group 8 are formed by synchronous belt wheels with the same modulus and the gradually increased tooth number, a stretching roller component 9, a synchronous belt 10 connecting the left driving wheel group and the right driving wheel group and an upper stretching mechanical module 11. The stretching roller assembly 9 is a core component of the equipment, and comprises 2 xn small synchronous belt wheels 9-1 which are matched with a driving wheel set and have the same outer diameter and the same number of teeth, a transmission gear 9-2 which is coaxial with the small synchronous belt wheels 9-1 and has the same number of 2 xn teeth, a pinion gear 9-3 which is matched with the transmission gear 9-2 and has the same number of 2 xn teeth, and (2 xn) -2 stretching rollers 9-4 which are fixed with the pinion gear 9-3 and rotate synchronously, a feeding conveyor belt driving roller 9-5 and a discharging conveyor belt driving roller 9-6. As shown in the figure: the surface of each stretching roller 9-4 is provided with two sections of spiral point-shaped bulges with opposite directions, so that on one hand, the friction between the rollers and the stretched material is increased, and simultaneously, the material can move forward and also move towards the middle of the roller group.

The driving motor 4 is started, the left driving wheel set 7 and the right driving wheel set 8 are driven to rotate through the motor belt 5 and the transmission shaft 6, the small synchronous belt wheel 9-1 is driven to rotate through the synchronous belt 10 which is connected with the left driving wheel set, the right driving wheel set and the rotating roller component, the small synchronous belt wheel 9-1 drives the small gear 9-3 which is fixed with the rotating roller to rotate through the transmission gear 9-2 which is coaxial with the small synchronous belt wheel 9-1, and therefore all the rotating rollers 9-4 in the stretching rotating roller component 9, the feeding conveying belt driving roller 9-5 and the discharging conveying belt driving roller 9-6 are driven to. Because the n synchronous belt pulleys forming the left and right driving wheel sets have the same module and gradually increased tooth number one by one, and the corresponding stretching rotary rollers comprise the same gears, transmission gears and small synchronous belt pulleys of the conveying belt driving roller, the rotating speeds of all the rollers are gradually increased from the feeding conveying belt driving roller to each stretching rotary roller to the discharging conveying belt driving roller in sequence. Placing the soft material on a feeding conveyor belt and feeding the soft material into a stretching roller group, when most of the material does not pass through a first roller and a small part of the material contacts or passes over a second roller, generating a pulling force on a material contact surface due to the fact that the second roller has higher rotating speed than the first roller, and repeating the steps, wherein every two adjacent rollers generate a pulling force on the material, and further gradually stretching the material; in order to prevent the phenomenon of upward rolling due to the fact that a contact surface is elongated but a non-contact surface is not elongated in the stretching process of the material, the upper mechanical module and the lower mechanical module are designed to be the same, when one surface of the material is elongated and starts to roll upwards, the material contacts a stretching roller set of the upper mechanical module, and the upper surface and the lower surface of the material are ensured to be elongated simultaneously; in addition, the surface of each stretching roller is provided with two sections of spiral point-shaped bulges with opposite directions, so that on one hand, the friction between the roller and the stretched material is increased, and simultaneously, the material can move towards the middle of the roller group while moving forwards, and the uniform stretching of the material is ensured.

The technical solution of the present invention is not limited to the limitations of the above specific embodiments, and all technical modifications made according to the technical solution of the present invention fall within the protection scope of the present invention.
