Description

Cutting assembly of shading sticky tape

Technical Field

The utility model relates to a sticky tape cutting correlation technique field, more accurate saying so relates to a cutting assembly of shading sticky tape.

Background

The shading sticky tape is a black double faced adhesive tape, and the shading sticky tape is attached between screen and backlight, can realize through the shading sticky tape that the connection between screen and the backlight is fixed, and the shading is glued simultaneously and still is played the effect of shading, guarantees the phenomenon of the peripheral disappearance light leak of screen when the backlight is lighted. The shading adhesive tape is attached to the edge of the screen to form a 'hui' shape, so that the middle of the screen is illuminated, and the periphery of the screen is shielded. The shading adhesive tape can be divided into an integral type shading adhesive tape and a sectional type shading adhesive tape according to the structure, wherein four edges of the integral type shading adhesive tape are of an integral structure, and at least one edge of the sectional type shading adhesive tape is independent. The processing of the sectional type light-shielding tape is difficult compared to the integral type light-shielding tape. Gaps exist between each edge of the sectional type shading adhesive tape, so that each single edge of the shading adhesive tape needs to be attached to the carrier film, and the shading adhesive tape can be processed after the attachment is completed. Because every limit of sectional type shading sticky tape all can be produced alone, the limit of sectional type shading sticky tape can adopt different materials to make to can satisfy different requirements that relate to, the suitability is better. When processing a sectional type shading tape, especially a shading tape with four independently spliced sides, in the prior art, an upper side and a lower side are generally processed on a carrier film, and then a whole shading tape raw material is attached on the carrier film to process a left side and a right side. After the whole shading adhesive tape raw material is attached and processed, only the left side and the right side are left, the left side and the right side are narrow, the large raw material in the middle is removed as a waste, the raw material loss is very large, the material utilization rate is low, and the manufacturing cost is high.

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.

As shown in fig. 1 and 2, the cutting assembly of the light-shielding tape of the present application includes a label cutter 10, a base roller 20, and a carrying shaft 30, wherein the label cutter 10, the base roller 20, and the carrying shaft 30 are arranged in an order from top to bottom, the label cutter 10, the base roller 20, and the carrying shaft 30 are arranged in parallel, the label cutter 10 is arranged adjacent to the base roller 20, and a gap 301 exists between the carrying shaft 30 and the base roller 20. The label cutter 10 is a circular cutter mold, the long blade 11 is uniformly distributed on the shaft body of the label cutter 10, and the long blade 11 extends along the axial direction of the label cutter 10. The masking tape stock material passes between the label cutter 10 and the base roller 20. Referring to fig. 4, the label cutter 10 and the bottom roller 20 rotate to cut the light-shielding tape material into a plurality of strips 100 having the same width, the carrier film 300 passes through the gap 301, and the bottom roller 20 rotates to attach the strips 100 to the carrier film 300.

Specifically, referring to fig. 3, the shaft circumference of the label cutter 10 is equally divided by a plurality of long blades 11. For example, 8 long blades 11 are uniformly distributed on the shaft body of the label cutter 10, the circumference of the shaft body of the label cutter 10 is 200mm, the 8 long blades 11 divide the circumference of the shaft body of the label cutter 10 into 8 parts, and each part has a length of 25mm along the circumference. During the rotation of the label cutter 10, the light-shielding tape raw material between the label cutter 10 and the base roller 20 is cut into a plurality of 25 mm-wide strips.

Referring to fig. 2, the carrier shaft 30 is a grooved shaft, the carrier shaft 30 has a middle portion 31 and butting portions 32 at both ends of the middle portion 31, the middle portion 31 has a smaller shaft diameter than the butting portions 32, and both butting portions 32 are in contact with the bottom roll 20 such that a gap 301 is formed between the middle portion 31 and the bottom roll 20. The carrier film 300 passes between the intermediate portion 31 and the base roller 20, and the carrier film 300 can be driven through the gap 301 by other means without rotation of the label cutter 10, the base roller 20, and the carrier shaft 30.

Referring to fig. 5, the cutting assembly of the masking tape is independent of other devices that process the masking tape, and the duty cycle of the cutting assembly of the masking tape is determined by the width of the masking tape product 200 being processed. That is, each time the carrier film 300 moves by the width distance of one light-shielding tape product 200, the cutting assembly of the light-shielding tape works to attach one strip 100 to the carrier film 300, so that the strips 100 are all located at the edge of the light-shielding tape product 200. For example, the width of the light-shielding tape product 200 is set to 150mm, and each time the carrier film 300 moves 150mm, the label cutter 10 rotates one frame to cut out one strip 100 with a width of 25mm, and the strip 100 is attached to the carrier film 300, so that the strip 100 is attached to the left and right sides of the light-shielding tape product 200, and continuous operation is possible.

Through the cutting assembly of shading sticky tape can effectively save the raw and other materials of shading sticky tape. For example, when a shading tape product with the width of 150mm is produced by adopting the prior art, the raw material of the shading tape with the width of 150mm needs to be used, only the raw material of the shading tape with the width of 25mm is needed through the cutting assembly of the shading tape, the raw material of the shading tape with the width of 125mm can be saved, and the material saving ratio reaches 83%. Therefore, the production cost can be effectively reduced by using the cutting assembly of the shading adhesive tape.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
