Description
Technical Field
[0001] This utility model relates to the field of auxiliary tools for printed product quality inspection machines, specifically a dust removal device for printed product quality inspection machines. Background Technology
[0002] Printed materials refer to finished products formed by transferring information such as text, patterns, images, or logos onto carriers such as paper, plastic film, metal foil, and fabric through printing technology. They are widely used in packaging, books, posters, labels, tickets, and other scenarios. Their types vary depending on the carrier and purpose. For example, plastic color-printed bags for food packaging, paper inner pages of books and magazines, and labels and stickers on the surface of goods are all printed materials, which are important carriers of product packaging and cultural dissemination.
[0003] An inspection machine is a device that uses optical imaging, machine vision, and automation technology to automatically detect quality defects in printed products. During operation, the printed products pass through the inspection area at a constant speed with the conveyor belt. The camera captures images of the printed product surface, and the system compares the real-time images with preset standard images to quickly determine whether defects exist. It is a key device in the printing industry to ensure product consistency and reduce the outflow of defective products.
[0004] Existing paper generates a lot of debris during processing and cutting. This debris stays on the paper surface and covers the printed image, interfering with the detection device's ability to inspect print quality. Therefore, a dust removal device for a print quality inspection machine is proposed to address this problem. Utility Model Content

This allows the detection module to identify the true state of the printed image and reduces the possibility of contaminants being misjudged as printing defects when the detection module detects the printed image due to easily adhered dust and other contaminants. The detection platform can perform double-sided cleaning and detection, and can switch between single-sided and double-sided detection, increasing the overall applicability of the detection platform.

[0008] Preferably, a fixed seat is fixedly connected to the side wall of the second support frame; a pair of AC ion bars are fixedly connected to the middle of the fixed seat; the AC ion bars are positioned near the side of the detection table; by removing static electricity from the surface of the printed material through the AC ion bars, the electrostatic attraction is eliminated, making it easier for contaminants to be swept by the flexible brush and absorbed by the dust suction head, further increasing the quality of contaminant removal and reducing dust residue caused by static electricity.

[0010] Preferably, a pair of second support rods are fixedly connected to the side wall of the first support frame; a pair of rotating seats are fixedly connected to the bottom end of the second support rods; a spotlight is rotatably connected to the top of the rotating seat; by rotating the spotlight to adjust the illumination angle, the light is focused on the detection position of the detection module, supplementing local brightness, eliminating shadows, providing sufficient visual recognition conditions for the detection module, and reducing missed detections caused by lighting problems.
[0011] Preferably, a buckle is fixedly connected to the bottom end of the vacuum pump; a flexible sleeve is fixedly connected to the middle of the buckle; the buckle can restrict the pipe to a fixed area in the middle, reducing the large shaking of the pipe connecting the vacuum pump and the vacuum head, which would cause the pipe to bend; and the flexible sleeve helps to reduce friction loss and protect the integrity of the pipe.

[0022] 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 scope of protection of the present utility model.
[0023] Specific implementation examples are given below.
[0024] like Figures 1 to 5As shown in the embodiment of this utility model, a dust removal device for a printed product quality inspection machine includes an inspection table 1; a first support frame 11 is fixedly connected to the top of the inspection table 1; a pair of inspection modules 12 are fixedly connected to the side wall of the first support frame 11; a second support frame 13 is fixedly connected to the top of the inspection table 1; a pair of linear motors 14 are slidably connected to the top of the second support frame 13; a fixing frame 15 is fixedly connected to the bottom of the linear motors 14; a pair of support plates 16 are arranged in the middle of the fixing frame 15; the support plates 16 are symmetrically arranged in the middle of the fixing frame 15; and a flexible... A brush 17 is used; a dust pump 18 is fixedly connected to the side wall of the second support frame 13; a dust pump 18 is fixedly connected to the bottom end of the detection table 1; a dust suction head 19 is fixedly connected to the side wall of the support plate 16; the dust pump 18 is connected to the dust suction head 19 through a pipe; during operation, the printed product to be tested can be pulled to the top of the detection table 1, then passed through the middle of the pair of support plates 16, and continued to be pulled through the middle of the first support frame 11, connecting the top of the printed product to the winding device, and then the winding device is started, and the printed product can move in the middle of the first support frame 11. At this time, the detection module 12 can inspect the printed images on the top and bottom sides of the printed product. During the detection process, when contaminants adhere to the paper surface, a pair of linear motors 14 are activated to reciprocate on the top of the second support frame 13, driving the fixed frame 15 to move. The flexible brush 17 at the bottom of the support plate 16, due to the reciprocating motion of the linear motors 14, sweeps the contaminants on both sides of the moving paper. Subsequently, a pair of vacuum pumps 18 are activated, and the vacuum head 19 adsorbs the contaminants swept by the flexible brushes 17, ensuring that the contaminants on both sides of the paper are absorbed. As the paper passes through the middle of the first support frame 11, the detection module 12 maintains cleanliness during the paper detection process. This is achieved through the linear motors 14... 4 drives the flexible brush 17 to sweep back and forth, which can first sweep away the contaminants on the top and bottom surfaces of the printed product. Then, the dust pump 18 simultaneously absorbs the swept contaminants through the dust suction head 19, which can reduce the secondary adhesion of contaminants and ensure the cleanliness of the surface of the printed product when it enters the detection area of the first support frame 11. This allows the detection module 12 to identify the true state of the printed image and reduce the possibility of contaminants being misjudged as printing defects when the detection module 12 detects the printed image due to easily adhered dust and other contaminants. The detection table 1 can perform double-sided cleaning and detection, and can switch between single-sided and double-sided detection, increasing the overall applicability of the detection table 1.
[0025] like Figure 3As shown, the top of the fixed frame 15 is threaded with a screw 2; the bottom of the screw 2 is rotatably connected to a support plate 16; a square hole 21 is opened on the side wall of the fixed frame 15; the support plate 16 is slidably connected to the square hole 21; during operation, when the paper thickness changes, the pressure of the flexible brush 17 sweeping the paper will change. At this time, a pair of screws 2 can be rotated to drive the support plate 16 to adjust the spacing. The support plate 16 can slide in the middle of the square hole 21, so that the support plate 16 always maintains a straight upward and downward movement; by rotating the screws 2 to drive the support plate 16 to adjust the spacing between the upper and lower support plates 16, it is ensured that the flexible brush 17 is closely attached to the paper surface, which can effectively remove dust for printed products of different thicknesses and improve the overall compatibility of the inspection station 1 with printed products of various specifications.
[0026] like Figures 1 to 2 As shown, a fixed seat 3 is fixedly connected to the side wall of the second support frame 13; a pair of AC ion bars 31 are fixedly connected to the middle of the fixed seat 3; the AC ion bars 31 are located near the side of the detection table 1; during operation, when the paper moves to the middle of the pair of flexible brushes 17 for sweeping, the dust on the paper surface will adhere more tightly due to static electricity. At this time, the pair of AC ion bars 31 can be activated. When the paper passes through the middle of the AC ion bars 31, the AC ion bars 31 can eliminate the static electricity on the paper surface; by removing the static electricity on the surface of the printed matter through the AC ion bars 31, the static attraction is eliminated, making the contaminants more smoothly swept by the flexible brushes 17 and absorbed by the dust suction head 19, further increasing the quality of contaminant removal and reducing dust residue caused by static electricity.
[0027] like Figure 1 As shown, a pair of first support rods 4 are fixedly connected to the top of the detection platform 1; a pair of support seats 41 are fixedly connected to the top of the first support rods 4; a rotating shaft 42 is rotatably connected to the top of the support seat 41; the rotating shaft 42 is located on both sides of the detection platform 1; during operation, when the paper moves and is detected in the middle of the detection platform 1, the rotating shaft 42 on both sides of the detection platform 1 can rotate and support the paper, so that the paper will not fall due to gravity and rub against the components; by setting the rotating shaft 42 on both sides of the detection platform 1 to form a rotating support to lift the printed product, it can reduce the scratches on the printed image caused by the friction between the printed product and the edge of the detection platform 1 when the printed product is detected by the detection module 12.
[0028] like Figure 5As shown, a pair of second support rods 5 are fixedly connected to the side wall of the first support frame 11; a pair of rotating seats 51 are fixedly connected to the bottom end of the second support rods 5; spotlights 52 are rotatably connected to the top of the rotating seats 51; during operation, when the detection module 12 detects the printed matter, it can activate multiple sets of spotlights 52 at the bottom of the second support rods 5, and then apply rotational force to the spotlights 52 to adjust the illumination angle of the spotlights 52 to the illumination position of the detection module 12, so that the surrounding brightness is sufficient when the detection module 12 detects; by rotating the spotlights 52 to adjust the illumination angle, the light is focused on the detection position of the detection module 12, supplementing the local brightness, eliminating shadows, providing sufficient visual recognition conditions for the detection module 12, and reducing missed detections caused by lighting problems.
[0029] like Figure 4 As shown, a buckle 6 is fixedly connected to the bottom end of the vacuum pump 18; a flexible sleeve 61 is fixedly connected to the middle of the buckle 6; during operation, when the linear motor 14 drives the fixed frame 15 to reciprocate, the pipe connecting the vacuum pump 18 and the vacuum head 19 will produce a large amount of shaking. At this time, the buckle 6 can restrict the pipe in the middle, and the flexible sleeve 61 can protect the pipe from being scratched; by restricting the pipe in the middle fixed area through the buckle 6, the large shaking of the pipe connecting the vacuum pump 18 and the vacuum head 19 is reduced, which may cause the pipe to bend. The flexible sleeve 61 works together to reduce friction loss and protect the integrity of the pipe.
[0030] Working principle: The printed material to be inspected can be pulled to the top of the inspection table 1, then passed through the middle of a pair of support plates 16, and continued to be pulled through the middle of the first support frame 11, connecting the top of the printed material to the winding device. Then, the winding device is started, and the printed material can move in the middle of the first support frame 11. At this time, the inspection module 12 can inspect the printed images on both the top and bottom sides of the printed material. When contaminants are attached to the paper surface, a pair of linear motors 14 can be started to reciprocate on the top of the second support frame 13, driving the fixed frame 15 to move. The bottom of the support plate 16 The flexible brush 17, due to the reciprocating motion of the linear motor 14, sweeps away contaminants on both sides of the paper as it moves through the center. Then, a pair of vacuum pumps 18 are activated, and the vacuum head 19 adsorbs the contaminants swept by the flexible brush 17, ensuring that the contaminants on both sides of the paper are absorbed. As the paper passes through the center of the first support frame 11, the detection module 12 maintains cleanliness during paper inspection. When the paper thickness changes, the pressure of the flexible brush 17 during sweeping changes; at this time, a pair of screws 2 can be rotated to adjust the support plate 16. The support plate 16 can slide in the middle of the square hole 21, ensuring that the support plate 16 always rises and falls in a straight line. When the paper moves to the middle of the pair of flexible brushes 17 for sweeping, the dust on the paper surface will adhere more tightly due to static electricity. At this time, a pair of AC ion bars 31 can be activated. When the paper passes through the middle of the AC ion bars 31, the AC ion bars 31 can eliminate the static electricity on the paper surface. When the paper moves and is detected in the middle of the detection table 1, the rotating shafts 42 on both sides of the detection table 1 can rotate and support the paper, so that the paper will not be affected by the weight. When the force causes the component to fall and rub against it, the detection module 12 can activate multiple sets of spotlights 52 at the bottom of the second support rod 5 when it detects the printed matter. Then, a rotational force is applied to the spotlights 52 to adjust the illumination angle of the spotlights 52 to the illumination position of the detection module 12, so that the surrounding brightness is sufficient when the detection module 12 detects the matter. When the linear motor 14 drives the fixing frame 15 to reciprocate, the pipe connected to the dust pump 18 and the dust head 19 will shake a lot. At this time, the buckle 6 can restrict the pipe in the middle, and the flexible sleeve 61 can protect the pipe from being scratched.
[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
