Description

Technical Field

[0001] The utility model relates to the technical field of self-adhesive label cutting, in particular to a local self-adhesive label cutting device. Background Art

[0002] With the development of the packaging industry and the demand for product diversification, self-adhesive labels have gained widespread application in areas such as product identification and advertising due to their ease of application, low cost, and aesthetic appeal. Self-adhesive labels typically consist of two parts: a silicone-coated backing paper (also known as release paper), which prevents the label from sticking; and an adhesive label with an adhesive that allows it to be directly adhered to various surfaces. In certain specific applications, such as internal labeling or special decoration of electronic products, ring-shaped self-adhesive labels are often used. These labels require cutting out the central circular portion of the label to achieve specific adhesion requirements.

[0003] When traditional equipment performs partial cutting, the label support is not stable enough, which can easily cause uneven cutting edges and affect the final quality of the product. This is especially true for cutting the circular area in the middle of a ring-shaped self-adhesive label. The traditional method is usually to use a semi-automatic cutting machine, that is, the label is placed on the cutting board and the cutter presses down to complete the cutting. This method is not only inefficient, but also because the blade gradually becomes blunt after multiple cuts, resulting in burrs on the cut edges of subsequent labels, seriously affecting the quality of the label.

[0004] Therefore, it is imperative to redesign a local self-adhesive label cutting device. Utility Model Content

[0005] In view of the above-mentioned defects of the prior art, the present invention provides a partial self-adhesive label cutting device, which aims to solve the problems of low cutting accuracy, low efficiency and burrs on the cutting edges in the partial cutting process of self-adhesive labels in the prior art.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a local self-adhesive label cutting device, including a frame, on which a conveying component, a cutter component, a support component and a control component are arranged, the cutter component is arranged above the conveying component, and the support component is arranged below the conveying component, the cutter component includes a pre-cutting module, a half-cutting module and a full-cutting module arranged in sequence along the conveying direction of the conveying component, the support component includes two label support modules corresponding to the pre-cutting module and the half-cutting module respectively, and a slotted support module corresponding to the full-cutting module below, the conveying component is used to convey the self-adhesive label, and the pre-cutting module, the half-cutting module and the full-cutting module are all controlled by the electrical signal of the control component to control the degree of downward pressure, and cooperate with the two label support modules and the slotted support module in the conveying component to complete the local cutting of the self-adhesive label.

[0007] Based on the above, the beneficial effect of a partial self-adhesive label cutting device is to solve the problems of low cutting accuracy, low efficiency and easy burrs on the cutting edge in the partial cutting process of self-adhesive labels in the prior art; it is mainly reflected in: the utility model sets a pre-cutting module, a half-cutting module and a full-cutting module, and these modules can be accurately controlled by electrical signals according to the preset downward pressure height of the control component. Specifically, in the pre-cutting stage, the rotary cutter of the pre-cutting module contacts the surface of the self-adhesive label with a lower pressure according to the preset pressure of the control component. The main purpose of this stage is to form a preliminary cutting mark on the surface of the self-adhesive label instead of completely cutting the material. In the half-cutting stage, the rotary cutter of the half-cutting module contacts the surface of the self-adhesive label according to the preset pressure of the control component. The self-adhesive label is cut at a set pressure and only reaches about half of the thickness of the self-adhesive label. The purpose of this stage is to further deepen the cutting marks, break some fibers of the self-adhesive label, but still maintain a certain connection. In the full-cutting stage, the rotary cutter of the full-cutting module completely cuts off the self-adhesive label according to the preset pressure of the control component. Since the connection of the materials has been weakened in the first two stages, the materials can be separated more cleanly at this stage without producing too much burrs, thereby ensuring the accuracy of the cutting process. In addition, during operation, the pre-cutting stage, half-cutting stage and full-cutting stage are carried out simultaneously according to the process of transmitting the self-adhesive label by the transmission component, which greatly improves the efficiency of local cutting of self-adhesive labels in the next batch.

The upper end surface of the second support block 322 is provided with an annular groove 3221, and the annular groove 3221 is adapted to the rotation path of the rotary cutter 213 of the full-cutting module 23.

[0028] The conveying assembly 1 includes an upper driving rod wheel group 11, a lower driving rod wheel group 12, an upper driving motor and a lower driving motor. The upper driving motor drives the upper driving rod wheel group 11 to rotate through belt engagement, and the lower driving motor drives the lower driving rod wheel group 12 to rotate through belt engagement. The upper driving rod wheel group 11 and the lower driving rod wheel group 12 rotate in opposite directions, so as to clamp and convey the self-adhesive label between the two.

The ejection cylinder 4 is used to push the partial cut portion of the self-adhesive label from the ejection portion 13 into the partial label recovery bucket 5.

[0031] In summary, the specific implementation of the present invention is as follows: first, the self-adhesive label enters the cutting area through the conveying assembly 1. The conveying assembly 1 is composed of an upper driving rod wheel group 11 and a lower driving rod wheel group 12. The upper driving rod wheel group 11 and the lower driving rod wheel group 12 are driven by their own driving motors, and the rotation directions of the upper driving rod wheel group 12 are opposite. This can effectively clamp the label for conveyance to prevent it from moving during cutting. From the input end to the output end of the conveying assembly 1, the upper driving rod wheel group 11 is sequentially provided with a label pre-cutting portion 111, a label half-cutting portion 112 and a label full-cutting portion 113. The distance between the three is equal to the distance of each self-adhesive label to be processed, ensuring that each rotary cutter 213 can cut at the correct position.

[0032] During cutting, the self-adhesive label needs to pass through the pre-cutting module 21, the half-cutting module 22 and the full-cutting module 23 in sequence. Each module is composed of a hydraulic cylinder 211, a rotary motor 212 and a rotary cutter 213. The control component controls the hydraulic cylinder 211 of each module to drive the rotary cutter 213 to different downward pressures through electrical signals to ensure that each module completes its own cutting function. The rotary motor 212 drives the rotary cutter 213 to perform the cutting operation. The specific work flow is as follows: each self-adhesive label The label is first driven by the hydraulic cylinder 211 of the pre-cutting module 21 to drive the rotary cutter 213 into the label pre-cutting part 111, and the first support cylinder 311 of the corresponding label support module 31 drives the first support block 312 to enter the pre-cutting support part 121, and then reaches the bottom end surface of the self-adhesive label. The rotary motor 212 drives the rotary cutter 213 to form a preliminary cutting mark on the surface of the self-adhesive label. The self-adhesive label that has completed the pre-cutting process is conveyed by the conveying component 1 to the half-cutting module 22, and the half-cutting module 2 2 drives the rotary cutter 213 into the half-cutting portion 112 of the label. The first supporting cylinder 311 of the corresponding label supporting module 31 drives the first supporting block 312 to enter the half-cutting supporting portion 122 and reaches the bottom end surface of the self-adhesive label. The rotating motor 212 drives the rotary cutter 213 to further deepen the cutting mark, so that some fibers of the self-adhesive label are broken but still remain connected. The self-adhesive label that has completed the pre-cutting process is conveyed by the conveying component 1 to the full-cutting module 23, and the full-cut The hydraulic cylinder 211 of the module 23 drives the rotary cutter 213 to enter the full-cutting portion 113 of the label. The corresponding second support cylinder 321 of the grooved support module 32 drives the second support block 322 to enter the full-cutting support portion 123 and reach the bottom end surface of the self-adhesive label. The rotating motor 212 drives the rotary cutter 213 to cooperate with the annular groove 3221 of the second support block 322, and finally completes the complete cutting of the self-adhesive label, which can ensure that the cutting edge is smoother and the burr phenomenon is reduced.

[0033] Finally, after cutting is completed, the self-adhesive label is conveyed by the conveying assembly 1 to the ejection portion 13, and the ejection cylinder 4 pushes the cut partial label downward from the ejection portion 13 into the partial label recovery barrel 5 for subsequent processing and recycling.

[0034] The above description is only the optimal solution embodiment of the present invention and is not intended to limit the present invention. Various modifications or replacements of the present invention made by those skilled in the art without departing from the essence and protection scope of the present invention should also be within the protection scope of the present invention.
