Description

Continuous cutting mechanism for food processing

Technical field

The utility model relates to a food processing mechanism, and more particularly to a food processing mechanism used as a three-dimensional spiral continuous shredding slice.

Background technique

At present, the food processor on the market has the functions of common shredding, slicing, cutting, dicing, grinding, etc., continuous shredding, and sliced products are also found in many markets. In summary, these continuous shreds and slices are The product has the following defects:

1. There is no clear distinction between continuous shredded slices and ordinary shreds, cut strips, and slicing speeds. For example, the Food Processor with Spiralizer Feature disclosed in the patent US20160101533, although the feed port is eccentric to the center by simple switching, The central rotating shaft drives the cutter head for continuous cutting, but since the central rotating shaft is on the central axis, it occupies the cutting area of the cutter head, and the common cutting, slitting, slicing speed range (800-1200 rpm) and continuous cutting Compared with the speed range required by wire slicing (180-350 rpm), there is a significant difference in speed. Therefore, such a simple replacement does not solve the problem of the speed requirement of continuous shredded slices. The requirement of continuous cutting slice for output speed belongs to the low speed range. The speed of the series motor is generally at least 10,000 rpm. To achieve low speed, deceleration is essential.

2. Products developed as accessories, such as Kitchenaid's spiralizer, although automatic cutting can be achieved, but continuous processing requires frequent loading and unloading of the clamping mechanism, the operation is cumbersome, and the food pretreatment requirements are high, the food should be cut flat at the beginning and end. The reason is that the product structure is open space.

3. Existing continuous cutting equipment, such as the cutter head is designed to be conical, and the blade is set on the tapered busbar, which inevitably produces a long food "tail" due to the tapered tip area. The blade is difficult to cover just enough, and the blade breaks the sharp point and breaks the food, which affects both the appearance of the product and the waste of food, such as the cutter of the planer blade device disclosed in the patent CN201620044172.3.

When the main engine is driven, the motor drives the sun gear link 2 to rotate, and the pinion gear 21 on the center gear link 2 meshes with the cutter wheel gear 33, thereby rotating the cutter gear 33 that is locked on the cutter holder 34, and the cutter gear 33 is rotated. The rotation simultaneously drives the cutter disk 31 fixed to the inner side thereof to rotate in the horizontal direction.

Specifically, as shown in FIG. 3 and FIG. 4, the cutter gear 33 is provided with a downward annular groove, and the lower end of the outer side wall of the inner circumference of the cutter gear 33 is provided with an outwardly protruding buckle 331, and the buckle 331 is the most Preferably, two or more are symmetrically distributed along the cutter wheel gear 33. The cutter holder 34 is provided with a circular boss 341 which cooperates with the annular groove, and the outer side wall of the inner circumference of the cutter wheel gear 33 and the circular boss 341 The inner side wall has a clearance fit, and the buckle 331 is fastened to the lower edge of the inner side wall of the circular boss 341. When the cutter wheel gear 33 is buckled into the cutter holder 34, the buckle position 331 is elastically deformed and worn. After the lower edge of the inner side wall of the circular boss 341, the buckle position 331 returns to the deformed size and then buckles the lower edge of the inner side wall of the circular boss 341, since the contact faces of the cutter wheel gear 33 and the circular boss 341 are both It is a clearance fit, so the pinion gear 21 on the sun gear link 2 is not affected to drive the cutter wheel gear 33 and the cutter disc 31 to rotate horizontally on the cutter holder 34, and the buckle 331 on the cutter head gear 33 realizes both the cutter The axial positioning of the disk gear 33 can be easily and quickly disassembled and cleaned to remove food residues in the gear gap.

Further, as shown in FIG. 5 and FIG. 6 , the wall of the circular boss 341 and the cutter wheel gear 33 can be sleeved with a bushing 35. The bushing 35 is preferably made of a metal material and is a rigid body. The cutter wheel gear 33 is available. Plastics such as POM are injection molded and are elastomers, and POM has self-lubricating effect, so it can achieve a more economical dynamic friction fit.

As shown in FIG. 1 , the feeding cylinder 41 is generally arranged in an elliptical shape. To prevent the food from rotating in the feeding cylinder 41 during processing, a guiding cylinder 5 can be sleeved on the feeding cylinder, and the inner wall of the feeding cylinder 41 can be The limiting groove is disposed, and the outer wall of the guiding cylinder 5 is provided with a cam that cooperates with the limiting groove to make the feeding cylinder 4 more stable, and the guiding cylinder 5 is sleeved with the pushing cylinder 6 when the food is When placed in the guide cylinder 5, the push cylinder 6 is pressed downward by an external force, so that the cutter disc 31 cuts the food, thereby achieving the purpose of continuous cutting.

As shown in FIG. 2 and FIG. 3, the cutter holder 34 is placed on the inner flange of the cooking cup 1 through its edge, and the edge of the cutter holder 34 is further provided with a slot 342, and the inner wall of the cup 1 is correspondingly disposed. The convex portion of the engaging groove 342 is engaged to prevent the disk holder 34 from being radially displaced, and the cup cover 4 is axially positioned when the cup body 1 is properly pressed against the upper portion of the holder base 34.

Optionally, as shown in FIG. 2, the cutter holder 34 can also be provided with a spare cutter disc 32 for different purposes, such as a thin cutting disc, a middle cutting disc, a coarse cutting disc or a sheet cutting disc, and the like. The alternate cutter disk 32 can be easily and flexibly interchanged with the cutter disk 31 to meet different cutting needs.

As shown in FIG. 4, the pusher cylinder 6 is further provided with a sharp needle 61, which can be used for fixing and preventing the food from being turned over during work, and can also be used for directly taking out the pusher cylinder 6 after the food is processed. The sharp needle 61 At the same time, the remaining food at the end is taken out to facilitate the continued operation of the next piece of food; for safety reasons, the tip of the sharp needle 61 should not be set too sharp, the tip is not more than 2 mm in diameter, the tip is set to be flat or curved, and the sharp needle 61 The height is not shorter than 5mm, and not longer than 10mm is the best. If it is too short, it is difficult to effectively extract the ingredients. It is difficult to ensure that the ingredients are not rotated during the cutting process. It is difficult to grasp and take out the ingredients after the operation; if it is too long, the ingredients are wasted.

The existing conical cutter head is easy to produce a food "tail", and the cutter cutter 31 can be a flat cutter disc, that is, the cutting edge is parallel or perpendicular to the bottom surface of the cut food, as shown in FIG. 4, at the central axis position of the cutter cutter 31. A conical tip 311 for fixing the food may be provided, the conical tip 311 fixing the food around the central axis of rotation, the food in the central region being pressed down along the conical surface, and a triangular knife at the large end of the conical surface may be provided The combination of the blade and the blade makes the food have no space to escape the tool, so that the food can be fully utilized, and the edge of the cutter 31 can be provided with a circle of outer arc or ring for easy grasping.
