Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, and more specifically, to a vacuum conveying device for die-cutting detection. Background Technology

[0002] Die-cutting, a core processing step in packaging, electronics, and printing, essentially involves using die-cutting blades to precisely cut rolls or sheets of material (such as paper packaging materials, films for electronic components, metal foil, and self-adhesive stickers) into predetermined shapes and sizes, ultimately forming specific structural components that meet the needs of downstream processes. "Die-cutting inspection" is a crucial step in ensuring the quality of die-cut products. It requires inspecting the cut materials for dimensional accuracy (such as the perpendicularity of the cut edges and hole diameter deviation) and appearance defects (such as burrs, damage, and indentations) to eliminate defective products.

[0003] Existing devices mostly rely solely on vacuum suction to fix materials on the conveyor belt, without a dedicated positioning and guiding structure. When materials (especially wide rolls or soft films) are affected by airflow disturbances or slight conveyor belt deviation during transport, they are prone to lateral shifts or longitudinal tilts. This causes the material's position at the inspection station to mismatch with the preset recognition area of ​​the inspection equipment. This not only requires manual shutdown to adjust the material position, reducing the production line cycle time, but may also lead to the invalidation of batch inspection data due to untimely adjustments. Therefore, a vacuum conveying device for die-cutting inspection is provided. Utility Model Content

[0005] This utility model provides the following technical solution: a vacuum conveying device for die-cutting detection, including a support frame, on which a conveying component is provided; The conveying assembly includes a conveyor belt mounted on a support frame, an exhaust hole extending through the conveyor belt, a pad at the top of the inner cavity of the conveyor belt, an air extraction hole extending through the pad, an air extraction box at the bottom of the air extraction hole, and two pipe joints on the air extraction box, with a conduit at one end of each pipe joint.

[0006] Optionally, in one possible implementation, several mounting plates are respectively provided on both sides of the support frame, and each mounting plate is provided with a through groove.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] This embodiment discloses a vacuum conveying device for die-cutting detection, which aims to solve the problem that existing vacuum conveying devices are not easy to position materials during the die-cutting process, resulting in low conveying accuracy, and subsequent die-cutting requires additional position adjustment and is inconvenient to use.

[0015] like Figure 1 As shown, the core supporting component of the vacuum conveying device is the support frame 1, which is made of high-strength aluminum alloy and has an overall "rectangular frame" structure.

[0016] The conveying assembly is the core component for realizing material conveying and vacuum adsorption, and its specific structure is as follows: like Figure 1 , Figure 2 , Figure 3 As shown, the conveyor belt 2 is made of food-grade polyurethane, which is wear-resistant and highly flexible, preventing scratches on die-cut materials such as paper, film, and metal foil. The conveyor belt 2 is mounted on the drive rollers at both ends of the support frame 1, forming a drive connection with the support frame 1. The running speed of the conveyor belt 2 can be adjusted by the subsequent motor 14 to adapt to the cycle time requirements of different die-cutting processes.

[0017] like Figure 3 As shown, exhaust holes 3 are evenly distributed in a matrix on the surface of the conveyor belt 2. The function of the exhaust holes 3 is to allow air between the material and the conveyor belt 2 to enter the air extraction holes 5 of the pad 4 through the exhaust holes 3 when the conveyor belt 2 covers the pad 4, thus providing an airflow channel for vacuum adsorption.

[0018] like Figure 4 As shown, a pad 4 is fixedly installed in the space between the top of the inner cavity of the conveyor belt 2 and the support frame 1. The pad 4 is made of rigid plastic, and its length is the same as the effective conveying length of the conveyor belt 2, and its width is the same as the width of the conveyor belt 2. The upper surface of the pad 4 is tightly fitted to the inner surface of the conveyor belt 2 to ensure that airflow does not leak from the gap. Air extraction holes 5 are drilled through the pad 4, and their positions correspond one-to-one with the exhaust holes 3 on the conveyor belt 2. The number of air extraction holes 5 is the same as the number of exhaust holes 3, forming a vertically connected airflow channel.

[0019] like Figure 4As shown, a vacuum box 6 is fixedly connected to the bottom of the pad 4. The vacuum box 6 is a sealed rectangular box structure. A pipe connector 7 is welded to the side wall of the vacuum box 6. The pipe connector 7 adopts a standard quick-connect structure, which facilitates quick connection and disassembly with the conduit 8. The conduit 8 is made of transparent PU hose, and its inner diameter matches the outer diameter of the pipe connector 7. The other end of the conduit 8 can be connected to an external vacuum pump. When the vacuum pump is started, a negative pressure is formed in the vacuum box 6. The material on the conveyor belt 2 is firmly adsorbed through the suction port 5 and the exhaust port 3, realizing stable material conveying and avoiding material deviation or wrinkling during the conveying process.

[0020] To solve the material positioning problem, adjustable positioning mechanisms were added to both sides of support frame 1, with the specific structure as follows: like Figure 1 , Figure 2 , Figure 3 As shown, several mounting plates 9 are evenly arranged on the frames on both sides of the support frame 1 along the length of the conveyor belt 2. The mounting plates 9 are detachably connected to the support frame 1 by bolts, which facilitates subsequent maintenance or replacement. Each mounting plate 9 has a through groove 10, which is elongated and provides guidance for the sliding of the slider 11.

[0021] like Figure 3 As shown, each chute 10 has a sliding block 11 slidably connected within it. The cross-section of the sliding block 11 is "T"-shaped to prevent it from falling out of the chute 10. An adjusting rod 12 is threaded onto the sliding block 11 in a direction perpendicular to the surface of the conveyor belt 2. The outer surface of the adjusting rod 12 is provided with anti-slip textures for easy manual rotation and adjustment by the operator. The length of the adjusting rod 12 extending beyond the sliding block 11 can be changed, thereby adjusting the position of the stop rod 13.

[0022] like Figure 1 , Figure 2 , Figure 3 As shown, a stop rod 13 is movably connected to the top of each pair of adjacent adjusting rods 12 via a bearing. The stop rod 13 is made of wear-resistant nylon, and its length is the same as that of the conveyor belt 2. The stop rod 13 is located at the two side edges of the conveyor belt 2. The distance between the two stop rods 13 can be adjusted by sliding the slider 11 within the chute 10 to accommodate die-cut materials of different widths. The height of the stop rod 13 can be adjusted by rotating the adjusting rod 12 to ensure that the stop rod 13 can both provide positioning and prevent excessive friction with the material surface.

[0023] like Figure 1As shown, a motor 14 is fixedly installed on one side of the bottom of the support frame 1. The motor 14 is a servo motor, which can achieve stepless speed regulation through a frequency converter to ensure the stable running speed of the conveyor belt 2. The output shaft of the motor 14 is connected to the drive roller at one end of the conveyor belt 2 through a belt 15. The belt 15 is a synchronous belt, which has the characteristics of high transmission accuracy and no slippage, ensuring that the power of the motor 14 is stably transmitted to the conveyor belt 2, so that the conveyor belt 2 runs at a uniform speed.

[0024] The specific working principle is as follows: First, according to the width of the die-cut material to be conveyed, the sliders 11 on the mounting plates 9 on both sides of the sliding support frame 1 are adjusted to adjust the position of the two side baffles 13 so that one end of them forms a longer feeding cavity; then, the adjusting rod 12 is rotated to adjust the position of the baffles 13. At the same time, the top of the baffles 13 is slightly higher than the surface of the material to avoid scratching the material and to play a positioning role.

[0025] Connect the conduit 8 to an external vacuum pump and start the pump to create a stable negative pressure inside the vacuum box 6. The negative pressure is then transmitted to the surface of the conveyor belt 2 through the vacuum hole 5 of the pad 4 and the exhaust hole 3 of the conveyor belt 2.

[0026] Start motor 14, which drives conveyor belt 2 to run at a constant speed via belt 15; place the die-cutting material at the feed end of conveyor belt 2, and the material adheres firmly to the surface of conveyor belt 2 under the action of vacuum adsorption force, and is conveyed to the discharge end with conveyor belt 2; during the conveying process, the material contacts the baffle rod 13 on both sides, and the baffle rod 13 plays a guiding and positioning role for the material to prevent the material from deviating; when the material is conveyed to the discharge end, it can directly enter the subsequent die-cutting and inspection process without additional position adjustment.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
