Detailed Description

Referring to fig. 1 to 7, fig. 1 to 7 disclose an embodiment of a cutter head structure of a label paper half-cutting digital display cutter assembly, which includes a mandrel 1, a slider 2 disposed above the mandrel 1 and abutting against the mandrel 1, a fixing frame 3 disposed at one side of the slider 2, a cutter holder 4 fixed above the slider 2, and a cutter 5, wherein the slider 2 is slidably disposed at one side of the fixing frame 3, the cutter holder 4 includes a first half holder body 41, a second half holder body 42, and a first connecting member 43 integrally connecting the first half holder body 41 and the second half holder body 42, the first half accommodating portion 411 is disposed at a side of the first half holder body 41 close to the second half holder body 42 by adjusting the first connecting member 43, be equipped with on the half support body 42 of second with half first holding portion 411 corresponds half holding portion 421 of second that matches, works as when half first support body 41 and half support body 42 of second are close to, half first holding portion 411 and half holding portion 421 of second are involutive to form fixed chamber 50 that is used for fixed cutting knife 5, the utility model discloses in, preferably, the side of fixed chamber 50 is the water droplet form. When the utility model is used, the first connecting piece 43 is adjusted, so as to pull open the space between the first half frame body 41 and the second half frame body 42 (as shown in fig. 6), then the cutting knife 5 is placed between the first half frame body 41 and the second half frame body 42, then the first connecting piece 43 is adjusted, the first half frame body 41 and the second half frame body 42 move relatively and approach until the cutting knife 5 in the fixed cavity 50 is fixed (as shown in fig. 7), so as to limit the cutting knife 5 in the fixed cavity 50, thus cutting can be carried out, when the cutting knife needs to be replaced, the first connecting piece 43 is directly adjusted, so as to pull open the space between the first half frame body 41 and the second half frame body 42, then the cutting knife 5 in the fixed cavity 50 is taken out, and a new cutting knife 5 is replaced, the utility model has very convenient operation of replacing the cutting knife 5, the blade can be replaced at will.

In the utility model discloses, preferred, the shape of cutting knife 5 is the rectangle. For circular knife among the prior art, the utility model provides a rectangular sword has avoided because of the poor cutting that leads to of concentricity of circular knife is inhomogeneous, and the consequence that the depth differs cuts more evenly. In addition, rectangular sword all uses a little part that all is the cutting edge to go the cutting at every turn, consequently uses the blunting back when the front end of cutting knife 5, loosens the knife rest, impels cutting knife 5 forward, and the unused cutting edge part at the back is used for the cutting again, like this for circular sword, rectangular cutting knife 5 can be used very long time, improves cutting knife 5's utilization ratio, reduces use cost.

The utility model discloses in, it is preferred, still include second connecting piece 21, be equipped with the guide way on the slider 2, the one end of second connecting piece 21 pass the guide way with mount 3 is connected, works as slider 2 for when mount 3 reciprocates, second connecting piece 21 is in relative slider 2 removes in the guide way. The connecting piece 21 can ensure that the sliding block 2 is connected with the fixed frame 3 and can ensure that the sliding block 2 can slide relative to the fixed frame 3.

The utility model discloses in, it is preferred slider 2 one side that is close to mount 3 is equipped with guide rail or spout, be equipped with on mount 3 with guide rail or spout correspond complex spout or guide rail, through the cooperation of guide rail and spout makes slider 2 slides and sets up one side of mount 3.

In the utility model, preferably, the cutting device further comprises a first spring 71 arranged on the front surface of the cutter assembly and a second spring arranged on the back surface of the cutter assembly, the upper end of the first spring 71 is fixed on the slider 2, the lower end of the first spring 71 is fixed on the fixed frame 3, and the first spring 71 is in an inclined state; the upper end of the second spring is fixed on the sliding block 2, the lower end of the second spring is fixed on the fixed frame 3, and the second spring is in an inclined state. In the utility model, the slide block 2 is in contact connection with the ejector rod 1, when the ejector rod 1 moves upwards, the slide block 2 is pushed to move upwards, so that the cutting knife 5 is driven to move upwards to cut the label; after cutting, the ejector rod 1 moves downwards, and when the gravity of the sliding block 2 is too small or the sensitivity of the cutter assembly is poor, the sliding block 2 cannot effectively and quickly move downwards along with the ejector rod 1, so that the sliding block 2 cannot reset, and the subsequent use is influenced. In the utility model, the first spring 71 and the second spring are arranged, the slide block 2 is connected with the fixed frame 3 through the first spring 71 and the second spring, when cutting, the ejector rod 1 pushes the slide block 2 to move upwards, the first spring 71 and the second spring in an inclined state have a downward inclined pulling force F, the pulling force F decomposes a horizontal component F1 and a vertical component F2, after cutting, the ejector rod 1 moves downwards, and the slide block 2 also moves downwards due to the action of the vertical component F2 of the first spring 71 and the second spring, thereby resetting; therefore, even if the gravity of the sliding block 2 is too small or the sensitivity of the cutter assembly is poor, the sliding block 2 can effectively and rapidly move downwards along with the ejector rod 1 and can be automatically reset quickly, the cutter assembly can still be used continuously when being cut next time, and the cutter assembly is more convenient to use.
