Description

Technical Field

[0001] The present application relates to the technical field of printing equipment, and in particular to an error detection device for printing equipment. Background Art

[0002] When printing equipment is printing papers in batches, some papers need to be printed with corresponding numbers, such as the numbers on invoices. Therefore, during the printing process, the printed numbers need to be checked for errors.

[0003] In the prior art, the error detection device is arranged at the paper output unit of the frame, specifically including a bracket mounted on the frame and a detection probe arranged on the bracket, that is, above the paper, to collect information about the code on the printed paper. The detection probe is electrically connected to a central control platform for processing the data collected by the detection probe, and the central control platform is electrically connected to a controller for executing the instructions sent by the central control platform after processing the scanned data. The controller is electrically connected to the driving parts at each unit in the printing device. In case of printing error, the printing device is stopped from operating, or reprinting is performed at the printing unit of the frame, and detection is performed again at the subsequent detection probe to complete the error detection work of the number.

[0004] However, the detection probe in the prior art is usually fixed to the bracket by bolts, and the detection range is relatively fixed. For printed papers of different sizes or formats, the corresponding information transmitted to the detection probe for detection is at different positions, and the applicability is poor, so further improvement is needed. Utility Model Content

[0005] In order to improve the applicability of the error detection device, the present application provides a printing equipment error detection device.

[0006] The present application provides a printing equipment error detection device, which adopts the following technical solution:

[0007] A printing equipment error detection device comprises a frame, a detection probe arranged on the frame, and an adjustment mechanism arranged on the frame for adjusting the position of the detection probe, wherein the detection probe is used to scan the printed serial numbers on the paper conveyed along the length direction of the frame; the adjustment mechanism comprises a first support rod for the detection probe to slide along the width direction of the frame and a first limiter for limiting the sliding of the detection probe, and the upper surface of the frame is vertically provided with support columns for mounting the two ends of the first support rod.

[0008] By adopting the above technical solution, since the positions of the numbers on different batches of paper are different, the corresponding positions on the same width direction of the frame are different. When detecting the numbers on the next batch of paper, it is necessary to first slide the detection probe to the corresponding position, and then use the first limiter to limit the sliding of the detection probe on the first support rod, so as to detect the numbers on the paper. Therefore, the detection probe is slidably connected to the first support rod and can slide along the width direction of the frame, so that the detection probe can adapt to the number positions at different positions on the same width direction of the frame, thereby increasing the error detection range of the error detection device for the number positions that can be printed, so as to improve the applicability of the error detection device.

[0009] The support column is provided for the installation of the first support rod so as to raise the first support rod and the detection probe.

[0010] Preferably, the length direction of the first support rod is parallel to the width direction of the frame, the end surface of the first support rod is provided with a first slide groove along its own length direction, the first slide groove extends to the outer surface of the first support rod, the detection probe is provided with a first slide plate slidably connected to the first slide groove, and the first limit member is arranged on the first slide plate to limit the sliding of the first slide plate.

[0011] By adopting the above technical solution, the detection probe can be installed on the first slide plate, thereby reducing the difficulty of installation.

[0012] Preferably, the first sliding groove extends to the upper surface of the first support rod, the first sliding plate is protrudingly provided with a mounting plate abutting against the side wall of the first support rod, and the detection probe is fixedly connected to the mounting plate.

[0013] By adopting the above technical solution, the first slide groove is extended to the upper end surface of the first support rod, which is relatively simple to operate compared to extending the first slide groove to the lower surface of the first support rod, so as to observe the restriction of the first limit member on the first slider. In this regard, a mounting plate is provided for the detection probe to be installed, thereby reducing the impact on the scanning path of the detection probe.

[0014] Preferably, the first support rod is detachably connected to the support column, and a plurality of detection probes are arranged at intervals along the length direction of the first support rod.

[0015] By adopting the above technical solution, corresponding to papers of different sizes, for papers of smaller sizes, there will be multiple papers in the width direction of the frame, thereby corresponding to multiple numbers, or corresponding to the same paper in the same width direction, there will be multiple numbers, so it is necessary to set a corresponding number of detection probes, and the first support rod is detachably connected to the support column to disassemble the first support rod. Moreover, since the first sliding groove provided on the first support rod extends to the two ends and the upper surface of the first support rod, it is convenient to slide a corresponding number of first slide plates corresponding to multiple numbers on the same width of the frame, so that a corresponding number of detection probes are set, so as to further improve the applicability of the detection probe.

[0016] Preferably, the first support rod slides along the height direction of the support column, and the support column is also provided with a first limiting member for limiting the sliding of the first support rod.

[0017] By adopting the above technical solution, for numbers of different sizes, for the detection probe of the same height, when the size of the number to be scanned is small, the scanning clarity may be poor, and for the number of larger size, the scanning may be relatively incomplete, affecting the accuracy of the number detection. Therefore, by sliding the first support rod along the height direction of the support column, the position of the first support rod in the height direction can be changed, that is, the position of the detection probe in the height direction can be changed, so as to adjust the position according to the numbers of different sizes, so as to further improve the applicability of the error detection device.

[0018] Preferably, the adjustment mechanism further comprises a second support rod for the first support rod to slide along the length direction of the frame, and the second support rod is also provided with a first limiting member to limit the sliding of the first support rod.

[0019] By adopting the above technical solution, since the spacing between two numbers in the length direction is different for papers of different sizes, the position transmitted to the detection probe will be different. Therefore, a second support rod is provided for the first support rod to slide, so that the detection probe can adapt to the numbering positions at different positions along the same length direction of the frame, thereby increasing the error detection range of the error detection device for the numbering positions that can be printed, thereby improving the applicability of the error detection device.

[0020] Preferably, the second support rod is provided with two support columns respectively installed on both sides and located below the first support rod, the length direction of the second support rod is parallel to the length direction of the frame, the upper surface of the second support rod is provided with a second slide groove along its own length direction, the side wall of the first support rod is protrudingly provided with a second slide plate, and the first limiting member is provided on the second slide plate.

[0021] By adopting the above technical solution, the second support rod is arranged below the first support rod, so as to adjust the length direction position of the first support rod in the frame, thereby adjusting the position of the corresponding detection probe, thereby adjusting the position of the detection probe in the horizontal direction.

[0022] Preferably, the second sliding groove extends to both end surfaces of the second support rod.

[0023] By adopting the above technical solution, the second slide groove is extended to both end surfaces of the second support rod, so that after the first support rod is slid away from the second support rod, the detection probe can be inspected and repaired.

[0024] Preferably, the frame is provided with a sliding seat for the support column to slide along the length direction of the frame, the length direction of the sliding seat is parallel to the length direction of the second support rod, and the sliding seat is also provided with a first limit piece for limiting the sliding of the support column.

[0025] By adopting the above technical solution and providing a sliding seat, since the first support rod is slidingly connected to the second support rod, and the second support rod is installed on the support seat, the position adjustment range of the first support rod in the length direction of the frame can be increased, thereby further improving the applicability of the error detection device.

[0026] In summary, the utility model has the following beneficial effects:

[0027] 1. By connecting the detection probe to the first support rod in a sliding manner and enabling it to slide along the width direction of the frame, the detection probe can be adapted to the numbering positions at different positions in the same width direction of the frame, thereby increasing the error detection range of the error detection device for the numbering positions that can be printed, thereby improving the applicability of the error detection device.

[0028] 2. By sliding the first support rod along the height direction of the support column, the position of the first support rod in the height direction can be changed, that is, the position of the detection probe in the height direction can be changed, so as to adjust the position according to the size number, so as to further improve the applicability of the error detection device.

[0029] 3. By providing a second support rod for the first support rod to slide, the detection probe can be adapted to the numbering positions at different positions along the same length direction of the frame, thereby increasing the error detection range of the error detection device for the numbering positions that can be printed, thereby improving the applicability of the error detection device.

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-3 , further details of this application are given.

[0035] The embodiment of the present application discloses an error detection device for printing equipment.

[0036] Example:

[0037] A printing equipment error detection device, referring to Figure 1 , Figure 2 , comprising a frame 1, a detection probe 2 disposed on the frame 1, and an adjustment mechanism 3 disposed on the frame 1 for adjusting the position of the detection probe 2. In this embodiment, the detection probe 2 is used to scan the printed serial numbers on the paper conveyed along the length direction of the frame 1. Among them, a support column 11 for mounting the adjustment mechanism 3 is vertically disposed on the upper surface of the frame 1, and two support columns 11 are provided and respectively disposed on both sides of the frame 1, and the support columns 11 are disposed perpendicular to the upper surface of the frame 1.

[0038] Among them, the adjustment mechanism 3 specifically includes a first support rod 31 for the detection probe 2 to slide along the width direction of the frame 1, a second support rod 32 for the first support rod 31 to slide along the length direction of the frame 1, and a first limiter 33 for limiting the sliding of the detection probe 2 and the first support rod 31. In this embodiment, a plurality of detection probes 2 are arranged at intervals along the length direction of the first support rod 31. In this embodiment, two detection probes 2 are specifically arranged on the first support rod 31.

[0039] In this embodiment, the length direction of the first support rod 31 is parallel to the width direction of the frame 1, and the end surface of the first support rod 31 is provided with a first slide groove 311 along its own length direction, and the first slide groove 311 extends to the upper surface of the first support rod 31. In this embodiment, the cross section of the first slide groove 311 along its radial direction is convex-shaped, and two first slide grooves 311 are arranged at intervals along the width direction of the first support rod 31. The detection probe 2 is provided with a first slide plate 21 that is slidably connected to the first slide groove 311. At this time, the first limiter 33 is provided on the first slide plate 21 to limit the sliding of the first slide plate 21.

[0040] Reference Figure 2 , Figure 3 The first limit member 33 specifically includes a limit bolt 331 and a limit plate 332 fixedly connected to the limit bolt 331. For the first limit member 33 in the first slide plate 21, the limit bolt 331 is threadedly penetrated into the first slide plate 21, and the limit plate 332 is located below the first slide plate 21. In this embodiment, the length of the limit plate 332 is longer than the slot width of the first slide groove 311. By rotating the limit bolt 331, when a gap is left between the limit plate 332 and the inner wall of the first slide groove 311, the limit plate 332 can be slidably connected to the first slide groove 311, and the first slide plate 21 is pushed to slide along the first support rod 31 to the corresponding position. When in place, the limit bolt 331 is rotated, and when the limit plate 332 is tightly against the bottom inner wall and bottom wall of the first slide groove 311, the first slide plate 21 is pressed tightly against the first support rod 31 to limit the sliding of the detection probe 2.

[0041] It should be noted that the width of the limit plate 332 can be set smaller than the slot width of the first slide groove 311, so that it can be directly slidably inserted into the first slide groove 311 from the upper surface of the first slide groove 311, which is more convenient for rotation. The width of the limit plate 332 can also be set larger than the slot width of the first slot, but smaller than the maximum width of the first slide groove 311, so as to reduce the possibility of slipping and falling due to the gravity of the detection probe 2 when the limit bolt 331 is loosened. The specific setting is based on the needs.
