Description

Technical Field

[0001] The utility model relates to the field of printing vision detection, and more specifically, to a printing overprint detection device for object packaging bags. Background Art

[0002] Object packaging bags are bags used to package various items and are usually made of materials such as plastics. In modern commerce, object packaging bags not only need to protect the items but also need to have a certain degree of aesthetics and publicity effect. To achieve these purposes, overprinting is often carried out on object packaging bags. However, during the overprinting process, due to the influence of various factors, inaccurate overprinting may occur. This requires the detection of the overprinting on object packaging bags.

[0003] Existing overprint detection usually relies on manual inspection one by one or visual cameras for image acquisition and then judgment and matching. Manual inspection one by one has a high labor cost, and vision is prone to deviation. When using visual cameras for acquisition, there may be significant differences in dimensions, shapes, etc. for different models of packaging bags, resulting in the deviation of the judgment of the printing position by the visual cameras, which will bring difficulties to subsequent judgment and matching. Content of the Utility Model

The technical problem to be solved by the utility model is that the manual detection cost is high, and for different models of packaging bags, there may be significant differences in dimensions, shapes, etc. when using visual cameras for acquisition, resulting in the deviation of the judgment of the printing position by the visual cameras, which will bring difficulties to subsequent judgment and matching.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

A first electric telescopic rod is fixedly installed on the bottom surface of the first bracket. An installation seat is fixedly installed on the bottom surface of the first electric telescopic rod. A detection head is fixedly installed on the bottom surface of the installation seat by screws. A waste product pushing mechanism is arranged on the top surface of the base. A waste product box is fixedly installed on the outside of the base. A drawer is slidably connected inside the waste product box.

[0007] As Figures 1-5As shown, the specific implementation mode is as follows: By setting a linear laser emitter, two linear lasers are printed on the conveyor belt as the boundaries for overprint judgment. Through the double-headed screw and the sliding seat, the two linear laser emitters can slide towards or away from each other, so that the boundaries can be changed according to the overprint width on different packaging bags. The detection head is used to take pictures of the overprint images of the laser boundaries and transmit them to the computer.

[0008] In a preferred implementation mode, the waste pushing mechanism includes a second bracket, and the second bracket is fixedly installed on the top surface of the base. A second electric telescopic rod is fixedly installed on the bottom surface of the second bracket. A Z-shaped threaded sleeve is slidably connected inside the second electric telescopic rod. A rubber pad is installed on the bottom surface of the Z-shaped threaded sleeve. The second electric telescopic rod drives the Z-shaped threaded sleeve to slide through a driving mechanism.

[0009] In a preferred implementation mode, the driving mechanism includes a threaded rod.

[0011] In a preferred implementation mode, a chute is opened inside the slide rail, and the Z-shaped threaded sleeve is slidably connected to the chute.

[0012] In a preferred implementation mode, a first motor is fixedly installed on the outer side of the first bracket, and the output shaft of the first motor penetrates through the first bracket and is connected to the double-headed screw.

[0013] In a preferred implementation mode, a display screen is fixedly installed on the outer side of the first bracket, and a baffle is fixedly installed on the top surface of the waste bin.

[0014] In a preferred implementation mode, the thread directions at both ends of the double-headed screw are opposite, and the connection point of the threads at both ends is the midpoint of the double-headed screw.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] 3.

Detailed implementation mode

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Refer to Figures 1-5 , a printing overprint detection device for material packaging bags, including a base 1. A conveyor belt 2 is arranged inside the base 1. A first bracket 6 is fixedly installed on the top surface of the base 1. A double-headed screw rod 14 is rotatably connected inside the first bracket 6. Two sliding seats 10 are symmetrically threadedly connected to the double-headed screw rod 14. A linear laser emitter 11 is installed on the bottom surface of each sliding seat 10. A first electric telescopic rod 13 is fixedly installed on the bottom surface of the first bracket 6. An installation seat 16 is fixedly installed on the bottom surface of the first electric telescopic rod 13. A detection head 12 is fixedly installed on the bottom surface of the installation seat 16 through screws. A waste product pushing mechanism is arranged on the top surface of the base 1. A waste product box 3 is fixedly installed outside the base 1. A drawer 5 is slidably connected inside the waste product box 3.

[0028] As Figures 1-5 shown, the specific implementation method is as follows: By setting the linear laser emitter 11, two linear lasers are printed on the conveyor belt 2 as the boundaries for overprint judgment. Through the double-headed screw rod 14 and the sliding seats 10, the two linear laser emitters 11 can slide towards or away from each other, so that the boundaries can be changed according to the overprint width on different packaging bags. The detection head 12 is used to photograph the overprint image of the laser boundary and transmit it to the computer, and the conveyor belt 2 is driven by an external driving device.

[0029] The waste product pushing mechanism includes a second bracket 7, and the second bracket 7 is fixedly installed on the top surface of the base 1. A second electric telescopic rod 17 is fixedly installed on the bottom surface of the second bracket 7. A Z-shaped threaded sleeve 20 is slidably connected inside the second electric telescopic rod 17. A rubber pad 21 is installed on the bottom surface of the Z-shaped threaded sleeve 20. The second electric telescopic rod 17 drives the Z-shaped threaded sleeve 20 to slide through a driving mechanism.

[0030] The second electric telescopic rod 17 can be used to adjust the height of the Z-shaped threaded sleeve 20. Thus, when not in use, the Z-shaped threaded sleeve 20 is raised to avoid affecting the normal movement of the packaging bag. At the same time, while increasing the friction force through the rubber pad 21, the packaging bag is prevented from being damaged.

[0031] The driving mechanism includes a threaded rod 23, and the Z-shaped threaded sleeve 20 is rotatably connected in the slide rail 18. The threaded rod 23 is threadedly connected to the Z-shaped threaded sleeve 20. A second motor 19 is fixedly installed on the outer side of the threaded rod 23, and the output shaft of the second motor 19 penetrates through the slide rail 18 and is connected to the threaded rod 23.

[0032] By rotating the threaded rod 23, the Z-shaped threaded sleeve 20 can be driven to move, thereby pushing the defective packaging bags into the waste bin 3.

[0033] A T-shaped groove 15 is formed in the first bracket 6, and each sliding seat 10 is slidably connected in the T-shaped groove 15.

[0034] A chute 22 is formed in the slide rail 18, and the Z-shaped threaded sleeve 20 is slidably connected to the chute 22.

[0035] The sliding seat 10 and the Z-shaped threaded sleeve 20 are limited by the T-shaped groove 15 and the chute 22 respectively, so that they cannot rotate and can move linearly.

[0036] A first motor 8 is fixedly installed on the outer side of the first bracket 6, and the output shaft of the first motor 8 penetrates through the first bracket 6 and is connected to the double-headed screw rod 14.

[0037] The first motor 8 provides a driving source for the rotation of the double-headed screw rod 14.

[0038] A display screen 9 is fixedly installed on the outer side of the first bracket 6, and a baffle 4 is fixedly installed on the top surface of the waste bin 3.

[0039] The baffle 4 prevents the packaging bags from sliding outside the waste bin 3. The number of waste products and the total number of detections can be displayed on the display screen 9, which is convenient for subsequent analysis and detection.

[0040] The thread directions at both ends of the double-headed screw rod 14 are opposite, and the connection point of the threads at both ends is the midpoint of the double-headed screw rod 14.

[0041] Furthermore, the two sliding seats 10 slide towards or away from each other.

[0042] When the utility model is in use, first place the packaging bag at the central part of the conveyor belt 2, then start the conveyor belt 2 to drive the packaging bag to move. At the same time, the first motor 8 can be started to drive the double-headed screw 14 to rotate. Through the two sliding seats 10 threadedly connected to the double-headed screw 14, the positions of the two linear laser emitters 11 are adjusted, so that the two linear laser emitters 11 are consistent with the overprint width on the packaging bag. Then start the two linear laser emitters 11 to emit laser onto the surface of the conveyor belt 2 as the boundary for judging whether the overprint is offset. Then the packaging bag moves to the bottom surface of the first bracket 6, and the detection head 12 takes an image and uploads it to the computer for analysis and judgment. If the overprint exceeds one of the laser boundaries, it is regarded as offset. At the same time, when adjusting the linear laser emitter 11, the height of the detection head 12 can be adjusted by the first electric telescopic rod 13, so as to facilitate the focusing of the detection head 12 and make the image taking clearer;

[0043] When the overprint is detected to be offset, the second electric telescopic rod 17 is started to lower the slide rail 18, so that the rubber pad 21 on the bottom surface of the Z-shaped threaded sleeve 20 contacts the packaging bag, and the second motor 19 is started to drive the threaded rod 23 to rotate, so that the Z-shaped threaded sleeve 20 moves in the direction of the waste bin 3, and then pushes the packaging bag into the waste bin 3. When there are more packaging bags in the waste bin 3, they can be taken out through the extraction box 5.

[0044] Only some exemplary embodiments of the present utility model are described by way of illustration. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present utility model.
