Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

It should be noted that, in the description of the present invention, the terms "first", "second", and the like are used for descriptive purposes only and for distinguishing similar objects, and no order is shown between the two, and no indication or suggestion of relative importance is understood. In addition, in the description of the present invention, "a plurality" means two or more unless otherwise specified.

Referring to fig. 1, the present embodiment discloses a cutting mechanism for screen printing, which includes a positioning assembly (not shown in the drawings) in signal connection with an external controller, a cutter assembly for shaping a product 100, and a base assembly as an auxiliary base of the cutting machine. The product 100 in this mode mainly is cardboard many, and original process flow is: firstly, printing a required pattern on a paper board through screen printing, externally expanding lines at the peripheral printing position of the pattern, and cutting the paper board through a cutter after the externally expanding lines are identified through a positioning piece of a subsequent cutting mechanism. The biggest drawback of the original process flow is that the cutting piece directly acts on the external expansion line, so that trace external expansion lines still remain, the difficulty of machine inspection or manual inspection is high, and the risk of complaint by customers exists.

In this embodiment, one of the preset pattern outlines on the product 100 is selected as the positioning portion, and the positioning assembly includes a cursor sensing element capable of identifying the position information of the positioning portion on the product 100. The positioning mode omits the introduction of an external expansion wire, and the phenomenon that the cutter directly acts on the external expansion wire can not occur. And the positioning part on the product 100 is used as a cutting reference point, and after the product 100 is cut, the product 100 can be known whether to be qualified or not by manually checking the comparison between the position of the actual positioning part and the position of the theoretical positioning part.

The expression form of the above-mentioned cutter is the cutter component in this application, wherein the cutter component includes the first cutter 1 that sets up with location portion corresponds on the product 100, the second cutter 2 that sets up with the product 100 outline correspondence. Preferably, in the first embodiment, the cross section of the knife in the horizontal plane is circular, and the positioning portion on the corresponding product 100 is a circular pattern. Because above-mentioned cursor location can produce less error when the cross cutting, this error probably is in each direction in the horizontal plane, chooses for use the location portion to be circular form, then can follow all directions homoenergetic and compare, and through artifical direct actual round hole position after being cut with predetermine the round hole position and directly compare, then can know whether qualified product 100. The cross-sectional shape of the positioning portion in the horizontal plane may also be a polygon, and may be modified adaptively according to the customer requirements, which will not be described herein again.

In the above embodiment, the first cutter element 1 and the second cutter element 2 are both located above the product 100 and extend toward the product 100. Preferably, the lower end of the first cutting insert 1 is located in the same horizontal plane as the lower end of the second cutting insert 2. Wherein the first cutter element 1 and the second cutter element 2 are each capable of cutting the product 100 such that the cut product 100 obtains a desired shape. The first cutter piece 1 and the second cutter piece 2 are both made of steel, wherein the performance requirements of the first cutter piece and the second cutter piece are that the steel is uniform in texture, the hardness combination of the cutter body and the cutter point is proper, the cutter point is subjected to quenching treatment and the like.

In the present embodiment, the base assembly includes an upper base 3 for fixing the cutter assembly and a lower base 4 for supporting the product 100, and preferably, the upper base 3 and the lower base 4 are stacked in the vertical direction, and the upper base 3 can be displaced relative to the lower base 4 in the horizontal plane. The first cutter element 1 and the second cutter element 2 are both fixedly arranged on the lower end face of the upper base 3, the upper base 3 is connected with a driving element, the driving element can be in signal connection with the cursor sensing element, so that the first cutter element 1 is indirectly in signal connection with the cursor sensing element, and the first cutter element 1 can be arranged right opposite to the positioning part on the product 100.

It should be noted that in the prior art, when the cutter assembly directly acts on the flaring line (i.e., the maximum allowable offset value), the cut product 100 is regarded as a defective product. In this application, if the cutter assembly directly acts on the profile of the allowed offset value, the cut product 100 is considered as a good product because no flaring line is introduced. Because the offset is basically smaller and basically controlled to be about 1 mm, the cutter assembly is very easy to directly act on the outward expansion line, and the design mode of the application can change waste products into qualified products and greatly improve the qualification rate.

In the embodiment, the buffer layer 5 made of the PET material is arranged between the lower base 4 and the product 100, the punching force is large in the cutting process, the cutting mode is adopted in the embodiment, and the cutter assembly can be in contact with the buffer layer 5 after being cut through the arrangement of the buffer layer 5, so that the cutter assembly is effectively protected.

In this embodiment, the cutting mechanism further includes a first dust removing member 6 located at the front end of the base assembly, and a second dust removing member 7 located between the first dust removing member 6 and the base. Specifically, the first dust removing part 6 includes two dust-binding rollers disposed correspondingly in the up-down direction, a gap for the product 100 to pass through is formed between the two dust-binding rollers, and both the two dust-binding rollers can abut against the surface of the product 100; the second dust-removing member 7 comprises an electrostatic dust-removing roller which can abut against the upper surface of the product 100. The first dust removing part 6 and the second dust removing part 7 are arranged, so that the surface of the product 100 has better cleanliness before the product 100 is cut, and external impurities can not damage the cutter assembly.

In this embodiment, a plurality of stopper posts 8 that extend in the vertical direction and can abut against the upper base 3 are provided at the edge of the lower base 4. The mode of mechanical limiting can ensure that the cutter assembly can not contact the lower base 4 all the time in the cutting process, and the action safety of the cutter assembly is effectively ensured. In addition, one or more of the upper end portions of the limiting columns 8 are provided with pressure sensing pieces used for detecting the pressure values of the punching of the cutter component. The cutter assembly is protected in a dual mode by adopting an electrical limiting mode and matching with a mechanical limiting mode.

The present invention has been explained by using specific embodiments, and the explanation of the above embodiments is only used to help understand the method and the core idea of the present invention; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the specific implementation and application scope, to sum up, the content of the present specification should not be understood as the limitation of the present invention.
