Detailed Description

In order to clearly understand the technical solution of the present invention, the present invention is further illustrated by the following embodiments in combination with the accompanying drawings.

Example 1:

the screw rod with the replaceable cutter provided by the embodiment comprises a screw rod body 1 and a cutter 2, as shown in fig. 1, the upper portion of the screw rod body 1 is a cutter shaft 3, the lower portion of the screw rod body is a spiral groove 4, the upper end of a bulge 5 forming the spiral groove 4 is a plane 6, as shown in fig. 3, the cutter 2 comprises a shaft sleeve 7 and a certain number of blades 8, the shaft sleeve 7 is sleeved on the cutter shaft 3, and the blades 8 are arranged on the shaft sleeve 7. In this embodiment, three blades 8 are arranged on the shaft sleeve 7 in a central symmetry manner.

Through the design, when the three-cutter-head cutter is installed, as shown in fig. 4, the screw body 1 is installed in the juice extractor, and then the three-cutter-head cutter 2 is installed on the cutter shaft 3. When the food squeezing machine works, food materials are firstly cut by the three-cutter-head cutter 2, and the cut food materials fall into the spiral groove 4 to be squeezed and juiced.

After the blade 8 of the device is damaged, only the cutter 2 needs to be detached for replacement.

Example 2:

as shown in fig. 5 and 6, in the present embodiment, in addition to the features described in embodiment 1, two blades 8 are arranged on the shaft sleeve 7 in a central symmetry manner.

For strength, the tool shaft 3 may be made of stainless steel.

Through the design, when the juicer is installed, as shown in fig. 7, the screw body 1 is installed in the juicer, and then the two-bit cutter 2 is installed on the cutter shaft 3. When the food squeezing machine works, food materials are firstly cut by the two-cutter-head cutter 2, and the cut food materials fall into the spiral groove 4 to be squeezed and juiced.

This device can change cutter 2 that has definite quantity blade 8 according to eating the material for eat the material cutting more abundant, the edible material after the abundant cutting gets into spiral groove 4's volume more, makes the extrusion force that the edible material received screw rod body 1 bigger, and the juice rate is higher.

Example 3:

as shown in fig. 8, in the present embodiment, a replaceable cutter screw is provided, in order to achieve better cutting effect, the blade 8 is obliquely arranged on the shaft sleeve 7, and the oblique direction is consistent with the rotation direction of the spiral groove 4.

Through the design, the blade 8 has inclination arrangement, so that the food material can be cut into more easily in rotation, jamming is reduced, and the cutting effect is better.

Example 4:

as shown in fig. 3 and 9, in the screw with replaceable tool according to this embodiment, a flat groove 10 is provided in the tool shaft 3 so that the tool 2 can rotate in synchronization with the spiral groove 4.

Through the design, the cutter shaft 3 and the shaft sleeve 7 are connected in a sleeved mode and do not slide, so that the screw body 1 can drive the cutter 2 to rotate synchronously.

Example 5:

as shown in fig. 2 and 10, in order to prevent the tool 2 from jumping up and down during use, the tool shaft 3 of the replaceable tool screw according to this embodiment is higher than the tool 2, and a fastening member 11 is disposed at the upper end of the tool shaft 3.

Through the design, the cutter 2 is fixed in the vertical direction, cannot jump up and down when in use, and runs more stably.

Example 6:

as shown in fig. 11, in the replaceable cutter screw provided by this embodiment, in order to facilitate adjustment of the number of the blades 8 on the cutter 2 and reduction of replacement cost after abrasion of the blades 8, the shaft sleeve 7 and the blades 8 are in a split structure, the shaft sleeve 7 is provided with a certain number of grooves 12, the blades 8 are provided with protrusions 13 matched with the grooves 12, the shaft sleeve 7 and the blades 8 are connected with the protrusions 13 through the grooves 12 in an insertion manner, and the grooves 12 and the protrusions 13 in the insertion manner may be in a dovetail groove structure, so that the blades 8 are kept relatively fixed with respect to the shaft sleeve 7 during operation.

Through the design, the number of the blades 8 on the cutter 2 can be adjusted by inserting the blades 8 into the groove 12, and the blades 8 are only required to be pulled out from the groove 12 for replacement after being worn, so that the cutter does not need to be replaced integrally, and the cost is saved.
