Abstract
Description
Technical Field
[0001] This utility model relates to the field of diffusion sheet die-cutting technology, specifically, to a multi-layer diffusion sheet die-cutting device. Background Technology
[0002] The feeding device for diffusion sheet processing is generally used to unwind and feed the diffusion roll, and transport the diffusion film to the die-cutting mechanism to be die-cut into several diffusion sheets. It is divided into single-layer die-cutting and multi-layer die-cutting. Multi-layer die-cutting is to place multiple unwinding rollers at the same time to draw out the diffusion sheet strips and neatly stack them into the die-cutting machine for multi-layer die-cutting.
[0003] However, due to the large thickness of the material strips during multi-layer die cutting, the cut diffuser sheets are not easy to fall off in sheets, and manual unloading is still required. Then the bottom edge of the material is rolled up, but manual operation is inefficient. At the same time, due to poor control of force, the bottom edge of the material is easy to break, which affects the rolling and the processing efficiency of the equipment. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;
[0021] Please see Figures 1-4In this utility model, a multi-layer die-cutting device for diffusion sheets includes a frame 1. From left to right, a combined support 2, a machine base 3, and a positioning frame 4 are fixedly installed on the top of the frame 1. Multiple matrix-distributed unwinding rollers 5 are installed on the combined support 2. A support frame 6 is installed on the top of the machine base 3. The right side of the support frame 6 is fixedly connected to the top of the positioning frame 4. A reciprocating cylinder 7 is installed on the support frame 6. A module 8 is installed at the bottom of the reciprocating cylinder 7. A die cutter 9 is installed at the bottom of the module 8. An active groove 10 is opened inside the module 8. A material ejection mechanism 11 is installed inside the active groove 10. A guide roller group 12 arranged at equal intervals is installed on the machine base 3. An edge roller 13 and a take-up roller 14 are installed on the positioning frame 4. A separating roller 15, which is horizontally aligned with the guide roller group 12, is installed on the left side of the positioning frame 4. A retraction roller 16 is installed at the bottom of the positioning frame 4.
[0022] In this invention, the frame 1 serves as the main body of the device. During use, the diffuser sheet rolls are first placed one by one on the combined support 2. Then, the ends of the rolls are all drawn out to form multi-layer strips. The ends are then introduced into the interior of each guide roller group 12, passing through the bottom of the unloading roller 16, and then through the dividing roller 15, where they are split in two and wound up by the edge roller 13 and the take-up roller 14 respectively. As the strips advance, the reciprocating cylinder 7 is simultaneously activated, driving the module 8 to move vertically back and forth, which in turn drives the die cutter 9 to cut the strips. Simultaneously, the ejector mechanism 11 ejects the cut portion along with the die cutter 9, preventing the diffuser sheet from getting stuck. Inside the die cutter 9, smooth and stable cutting is ensured. After cutting, the strip runs to the unloading roller 16, where the cut diffuser sheet is squeezed off by the unloading roller 16, realizing automatic feeding. This achieves the advantages of automated feeding, reduced manual operation, stable equipment operation, and improved equipment output efficiency. It solves the problems in the existing technology where the strip is thick and the cut diffuser sheet is not easy to fall off in pieces, requiring manual feeding. Then the bottom edge of the material is rolled up, which is inefficient due to low manual operation. At the same time, due to poor force control, the bottom edge of the material is easy to break, affecting the rolling and the processing efficiency of the equipment.
[0023] Please see Figure 2 The ejector mechanism 11 includes a sliding block 111 and two springs 112. The top of the sliding block 111 is slidably connected to the inside of the movable groove 10. The top of the sliding block 111 is elastically connected to the inside of the movable groove 10 through the springs 112. The outer side of the sliding block 111 is slidably attached to the inner side of the die cutter 9.
[0024] In this invention, the sliding block 111 moves synchronously with the die cutter 9 to contact the raw material strip. At this time, the sliding block 111 is held up by the material strip, and the die cutter 9 continues to descend and cut. After cutting, the sliding block 111 presses down the cut material piece to prevent it from rising with the die cutter 9. Meanwhile, the spring 112 pushes the sliding block 111 to make its material ejection effect on the diffuser sheet more stable.
[0025] Please see Figure 2 The top of the sliding block 111 is fixedly connected to two guide rods 113, and the top ends of the two guide rods 113 pass through and slide to the inside of the module 8.
[0026] In this invention, the guide rod 113 makes the vertical sliding of the sliding block 111 more stable.
[0027] Please see Figure 1 and Figure 3 The outer side of the ejector roller 16 is fixedly connected with four equally spaced protrusions 161, the spacing of which corresponds to the spacing of the die-cutting blocks.
[0028] In this invention, four equally spaced protrusions 161 on the outer side of the unloading roller 16 contact and squeeze each set of cut diffuser sheets, causing them to fall off, thus achieving automated material discharge.
[0029] Please see Figure 1 The receiving box 17 is placed on the top of the machine base 3, and the receiving box 17 is located directly below the unloading roller 16.
[0030] In this invention, the dropped diffuser sheets are collected by the receiving box 17, which has the advantage of being easy to collect.
[0031] Please see Figure 2 Among them, the bottom of the sliding block 111 is provided with equally spaced strip grooves 18.
[0032] In this invention, the strip groove 18 prevents the sliding block 111 from adsorbing with the bottom diffuser sheet, facilitating separation and not affecting the normal conveying and movement of the diffuser sheet strip.
[0033] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
