Description

Technical Field

[0001] This utility model relates to the field of paper testing technology, specifically to a device for inspecting scratches and surface dirt on paperboard used for assembling paper boxes. Background Technology

[0002] During the production of packaging boxes, scratches on the surface of the face paper are prone to occur. In the DPO (Digital Printing and Coating) process, foreign matter such as oil stains, dust, glue residue or chemical stains, hot stamping deviation, pinholes, and rough edges can adhere to the material surface, resulting in more than ten types of quality defects. Currently, quality inspection mainly relies on manual visual inspection. When quality inspectors use the naked eye to inspect scratches on the face paper and dirt in the DPO, it is not easy to find individual small scratches. This results in disadvantages such as low inspection pass rate, high missed inspection rate, difficulty in identifying minor defects, and poor standard consistency.

[0003] Therefore, it is necessary to propose an inspection device with a high pass rate. Utility Model Content

[0004] The purpose of this invention is to provide a device for inspecting scratches on paperboard and dirt on the surface of DPO (distilled plastic packaging) for paperboard assembly. By setting movable plates and fixed plates on both sides above the platform, the position and height of the light strip can be adjusted to provide supplementary lighting, thereby improving the pass rate of manual visual inspection and reducing the missed inspection rate.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following solution:

[0006] A device for inspecting scratches on paperboard and surface dirt on DPO for cardboard box assembly is characterized by comprising a platform and a fixed plate and a movable plate located on both sides above the platform. Guide rods penetrating an L-shaped plate are respectively provided above the fixed plate and the movable plate. A light strip is provided on the vertical part of the L-shaped plate, and a threaded rod for height adjustment is passed through the horizontal part of the L-shaped plate.

[0007] Furthermore, multiple sliding grooves are provided on one side of the platform adjacent to the moving plate. A limiting plate is provided inside the sliding groove located in the center, and sliding rollers are provided in the other sliding grooves. The sliding rollers are adapted to the sliding blocks provided at the bottom of the moving plate.

[0008] Furthermore, a mounting plate for assembling bearings is provided at the center of the movable plate and the fixed plate, and the bottom end of the threaded rod is located inside the bearing.

[0009] Furthermore, the outer periphery of the guide rod passes through the second limiting plate and the sleeve respectively, and the second limiting plate and the sleeve are located at the bottom above the horizontal part of the L-shaped plate and are threaded together.

[0010] Furthermore, the surface of the limiting plate is provided with multiple screw holes, and the movable plate is provided with locking screws that are compatible with the screw holes.

[0011] Furthermore, the outer periphery of the light strip is provided with a housing that is detachably connected to the L-shaped plate.

[0012] Furthermore, the two light strips are positioned opposite each other.

[0013] Furthermore, it also includes a controller located above the platform, which is electrically connected to each lamp.

[0014] Furthermore, a protective goggle is fitted around the outer periphery of the platform, and the protective goggle is made of amber transparent acrylic sheet.

[0015] The beneficial effects of this utility model are:

[0016] This invention utilizes a fixed plate and a movable plate above a platform, with guide rods and threaded rods positioned above the two plates. The movable plate moves left and right to adjust the distance between the two light strips, while the threaded rod drives an L-shaped rod to move up and down to adjust the height of the light strips. This allows the position of the light strips to adapt to the sample being tested, thereby improving the pass rate. It can magnify even minor defects, thus identifying the type of defect and reducing the false negative rate. Protective eye protection is also included to reduce eye fatigue and injury for workers.

[0024] Example 1

[0025] Embodiment 1 of this utility model is a device for inspecting scratches on paperboard and surface dirt on DPO for paperboard assembly. It includes a platform 1 and a fixed plate 2 and a movable plate 3 located on both sides above the platform 1. Guide rods 4 that pass through an L-shaped plate 5 are respectively provided above the fixed plate 2 and the movable plate 3. A light strip 7 is provided on the vertical part of the L-shaped plate 5, and a threaded rod 6 for height adjustment passes through the horizontal part of the L-shaped plate 5.

[0026] Reference Figure 1 This application mainly sets a fixed plate 2 and a movable plate 3 above the platform 1, and fixes guide rods 4 and threaded rods 6 above the two plates respectively, which pass through L-shaped plates 5. L-shaped plates 5 are used to assemble light strips 7. Movable plate 3 will adjust the position between the two light strips 7, and threaded rods 6 will adjust the height of light strips 7, so that the position of light strips 7 is adapted to the sample to be tested, thereby improving the pass rate. Due to the adjustment of the light, minor defects can be magnified, thereby identifying the type of defects and reducing the missed detection rate.

[0027] The horizontal part of the L-shaped plate 5 primarily provides conditions for the installation of the guide rod 4 and the lifting and lowering movement of the threaded rod 6, while its vertical part primarily provides conditions for the installation of the light strip 7. There are two guide rods 4 here, but they can be set according to actual conditions; they will not be listed here individually.

[0028] It should be noted that multiple sliding grooves 10 are provided on one side of the platform 1 adjacent to the movable plate 3. A limiting plate 12 is provided inside the sliding groove 10 located in the center, and sliding rollers 11 are provided in the remaining sliding grooves 10. The sliding rollers 11 are adapted to the sliding blocks 30 provided at the bottom of the movable plate 3. By providing sliding rollers 11 inside the sliding grooves 10, the sliding blocks 30 at the bottom of the movable rod can move left and right on the sliding rollers 11, thereby allowing the light strip 7 above the movable plate 3 to move closer to or further away from the light strip 7 above the fixed plate 2, improving the utilization rate of the device. The assembly of the sliding block 30 and the sliding roller 11 is as follows: Figure 3 .

[0029] To enable the threaded rod 6 to drive the L-shaped rod and the overall light strip 7 to adjust their height, a mounting plate 60 for assembling a bearing 61 is provided at the center of the moving plate 3 and the fixed plate 2. The bottom end of the threaded rod 6 is located inside the bearing 61. The mounting plate 60 fixes the threaded rod 6 above the moving plate 3, and the mounted bearing 61 provides rotational space for the threaded rod 6. Thus, when the hand holds the end of the threaded rod 6 and rotates it, the L-shaped plate 5 moves during rotation. This allows both ends of the L-shaped plate 5 to move up or down along a straight line under the action of the guide rod 4, preventing deviation during movement.

[0030] It should be noted that after the height adjustment is completed, the L-shaped rod will not move because the threaded rod 6 is threadedly connected to the L-shaped rod and its height within the threaded rod 6 is not affected.

[0031] In some preferred embodiments, the outer periphery of the guide rod 4 passes through the second limiting plate 40 and the sleeve 41, respectively. The second limiting plate 40 and the sleeve 41 are located at the bottom above the horizontal part of the L-shaped plate 5 and are threaded together. The second limiting plate 40 and the sleeve 41 mainly provide a limiting function for the installation of the horizontal part of the L-shaped plate 5. At the same time, screws are used to sequentially pass through the second limiting plate 40, the L-shaped plate 5 and the sleeve 41 to firmly install the L-shaped rod between the second limiting plate 40 and the sleeve 41.

[0032] Reference Figure 2 The limiting plate 12 has multiple screw holes 120 on its surface, and the movable plate 3 has locking screws 31 that are adapted to the screw holes 120. When the movable plate 3 moves to the appropriate position, the locking screws 31 on the movable plate 3 are rotated to pass through the screw holes 120, thereby limiting the position of the entire movable plate 3 and facilitating disassembly and adjustment to the next position. The number of screw holes 120 can be set according to the actual situation, and they are not listed here.

[0033] Example 2

[0034] This embodiment 2 is implemented based on embodiment 1, wherein the outer periphery of the light strip 7 is provided with a housing 70 that is detachably connected to the L-shaped plate 5. The two light strips 7 are also arranged opposite to each other. The detachable assembly of the housing 70 facilitates the replacement of light strips 7 with different wattages to meet the testing requirements of different samples.

[0035] Furthermore, the device includes a controller 8 located above the platform 1, which is electrically connected to each of the light strips 7. The controller 8 not only drives the switching of the two light strips 7, but also adjusts the brightness of the light strips 7 at this power level, so that different brightness levels meet different needs and improve the utilization rate of the device.

[0036] In some preferred embodiments, a protective goggle 9 is fitted around the outer periphery of the platform 1. The protective goggle 9 is made of amber-colored transparent acrylic sheet. The protective goggle 9 is mainly used to prevent eye fatigue caused by prolonged focusing on light by workers. At the same time, the amber-colored transparent acrylic sheet also blocks light, reducing eye fatigue.

[0037] The working principle of this application is as follows: When in use, the sample to be tested is placed on the platform 1 near the fixed plate 2. The moving plate 3 is pushed close to the sample by hand. The locking screw 31 is rotated so that its bottom end enters the screw hole 120 of the limiting plate 12 to limit the position of the moving plate 3. The threaded rod 6 is manually rotated to drive the L-shaped plate 5 to move up or down in a straight line under the action of the guide rod 4. The height of the light strip 7 is adjusted, and the goggles 9 are put on the platform 1. The light strip 7 is turned on and the brightness is adjusted by the controller 8 to perform defect detection of the sample to be tested, thereby improving the inspection pass rate and reducing the missed detection rate during manual visual inspection.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent substitutions, and improvements made to the above embodiments based on the technical essence of the present utility model and within the spirit and principles of the present utility model shall still fall within the protection scope of the present utility model.
