Description

TECHNICAL FIELD

[0001] The utility model relates to the field of bulking equipment, especially to an easy-to-clean anti-blocking bulking machine. BACKGROUND

[0002] The bulking machine belongs to a kind of equipment for processing bulking food, such as processing rice, corn, soybean, wheat and the like in daily life. Its main working principle is to convert mechanical energy into heat energy, and the heat generated when the machine rotates is used to extrude the food. The most obvious feature of the bulking food is that the volume is increased.

[0003] The existing small bulking machine structure is shown in Figure 1 and Figure 2 , which includes a machine body assembly, a machine barrel assembly and a machine head assembly, as well as a driving assembly and a cutting assembly, etc. The machine body assembly includes a machine box 11, a belt pulley 12 and a feeding hopper 13. The machine barrel assembly includes a machine barrel 21 and a screw 22 and a screw sleeve 23 inside it. The outer wall of the end of the machine barrel 21 is provided with a threaded section 24. The machine head assembly includes an extruder head 31. The rear end of the extruder head 31 is provided with a nut section 32 matched with the threaded section 24. At least one pair of flat surfaces 33 is provided on the side wall. The existing problems of this bulking machine are:

[0004] 1. The machine head and the machine barrel are directly connected and fixed through a threaded structure. During the working process of the bulking machine, the food is easily extruded into the gap between the threads, making it very difficult to disassemble when cleaning or replacing the machine head. It needs to be removed with a wrench or after calcination, which is time-consuming and laborious and causes damage to the structure.

[0005] 2. The threaded structure of the machine head and the machine barrel is easily damaged under high temperature and high pressure working environment and difficult disassembly, with short service life.

[0006] 3. The screw needs to exceed the length of the screw sleeve and extend into the machine head, so the concentricity of the screw and the machine head has high requirements. However, the concentricity of the screw of this structure is easily changed, which may cause food leakage and reduce the bulking rate.

[0007] 4. The above problems cause the machine head structure to be easily blocked, which easily damages the equipment and makes it very difficult to disassemble and clean. UTILITY MODEL CONTENTS

[0008] The utility model aims to solve the above-mentioned problems of the prior art and provide an easy-to-clean anti-blocking bulking machine.
