Description

A kind of transverse cuts cutter

Technical field

The utility model relates to the cutting tool that a kind of the food enterprises is used.

Background technology

Transverse cuts cutter on streamline generally adopts driving wheel to drive rocking arm to press down the form of cutting knife at present, and it is long that its major defect is that cutting knife pressed down with resetting time, and when line speed is very fast, otch out-of-flatness, affects cut quality.Also utilize at present monolithic processor controlled cutting knife, can control by air pump, but its cost is higher, and be not easy to safeguard.

Utility model content

The purpose of this utility model is: overcome the defect of above-mentioned prior art, propose a kind of transverse cuts cutter.

In order to achieve the above object, the transverse cuts cutter the utility model proposes, comprise knife rest, the cutting knife that can slide up and down along knife rest, it is characterized in that: described cutting knife both sides are fixed with slide block, between slide block and knife rest, reseting pressuring spring is installed, the back middle position of described cutting knife is fixed with depression bar, on knife rest, by bearing, be provided with and be positioned at depression bar oblique upper for pressing down the cam of described depression bar, the head of described cam has outer convex globoidal, and the first half of described depression bar head has the inner concave arc surface matching with the outer convex globoidal of described cam.

The utility model further improves and is:

1, the inner concave arc surface of described depression bar is positioned at the side away from cam, and described depression bar head also has outer convex arc surface near a side of cam, and the outer convex arc surface of described depression bar is positioned at the Lower Half of depression bar head.

2, the interior concaved circular cambered surface of described depression bar head and the outer convex arc surface of depression bar head are tangent at joining part.

3, described slide block offers vertical through holes, and described knife rest is provided with the guiding pin passing from described vertical through holes, and the top of guiding pin is fixed with limited block, and described reseting pressuring spring is sleeved on guiding pin, and two ends prop up respectively knife rest and slide block lower surface.

4, fixing stop collar also on described knife rest, described depression bar is inserted in this stop collar and slides.

5, described stop collar lower surface flushes with limited block lower surface.

The utility model cutting tool is realized respectively pressing down of cutting knife and is resetted by cam and reseting pressuring spring.Wherein, the head of cam matches with depression bar head, and in cam contact depression bar head, both are face contacts, and when being about to depart from, both contact for line, the advantage of this design be can be more stable suppressing action power is provided, be applied to fast on cutting knife; After turning an angle, cutting knife drops to extreme lower position, and now cam head and depression bar head are line and contact and start and depart from, and depression bar head loses downforce at short notice, under the effect of reseting pressuring spring, lifts fast; Owing to having adopted the form of cam and depression bar, guarantee, under the prerequisite of cutting knife stroke, greatly to have shortened the used time that cutting knife presses down and lifts, realize to product fast, precisely cutting, and otch is smooth, defect rate is extremely low.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the utility model is further described.

Fig. 1 is transverse cuts cutter original state schematic diagram.

Fig. 2 is transverse cuts cutter pressed status schematic diagram.

Number in the figure is schematically as follows:

1-knife rest, 2-cutting knife, 3-limited block, 4-slide block, the 5-pin that leads, 6-reseting pressuring spring, 7-depression bar, 8-stop collar, 9-cam.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described further.

As shown in Figure 1 and Figure 2, the present embodiment transverse cuts cutter, comprise knife rest 1, the cutting knife 2 that can slide up and down along knife rest 1, cutting knife 2 both sides are fixed with slide block 4, between slide block 4 and knife rest 2, reseting pressuring spring 6 are installed, in this example, slide block 4 offers vertical through holes, and knife rest 1 is provided with the guiding pin 5 passing from vertical through holes, and the top of guiding pin 5 is fixed with limited block 3, reseting pressuring spring 6 is sleeved on guiding pin 5, and two ends prop up respectively the lower surface of knife rest 1 and slide block 4.The back middle position of cutting knife 2 is fixed with depression bar 7, on knife rest 1, by bearing, be provided with and be positioned at depression bar 7 oblique uppers for pressing down the cam 9 of described depression bar 7, the head of cam 9 has outer convex globoidal, the first half of depression bar 7 heads has the inner concave arc surface matching with the outer convex globoidal of cam 9, the inner concave arc surface of depression bar 7 is positioned at the side away from cam, depression bar 7 heads also have outer convex arc surface near a side of cam 9, the outer convex arc surface of depression bar is positioned at the Lower Half of depression bar head, wherein, the outer convex arc surface of the interior concaved circular cambered surface of depression bar 7 heads and depression bar 7 heads is tangent at joining part.

More stable with contacting of depression bar in order to guarantee cam, in this example on knife rest 1 fixing stop collar 8, depression bar 7 is inserted in the interior slip of this stop collar 8.In this example, stop collar lower surface flushes with limited block lower surface, realizes spacing to what jump on cutting knife simultaneously.

As can be known from Fig. 1, when cutter during in original state cam not yet contact with depression bar, now cutting knife is positioned at apical position; After cam rotates to an angle, its head contacts with depression bar, and cutting knife starts to be pressed down; Cam is rotated further after certain angle, and cutting knife is pressed down to lowermost end (as shown in Figure 2), and now, depression bar head and cam start to depart from, and cutting knife is upspring fast under the effect of reseting pressuring spring.

In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
