A label production detection device convenient for positioning

Abstract

This utility model relates to the technical field of testing devices for label production, and discloses a label production testing device that is easy to position. It includes a control console, a bidirectional screw rotatably connected between two side plates, two sliders threadedly connected to the outer surface of the bidirectional screw, a vertical plate on the upper surface of the sliders, and two positioning blocks slidably connected to the outer surface of the unwinding roller. This utility model works by first placing the label roll onto the unwinding roller, then having one end abut against one of the positioning blocks, and then moving the other positioning block to fit against the other end of the label roll. The unwinding roller is then mounted on the vertical plate. A motor is started to drive the bidirectional screw to rotate, causing the sliders on both sides to slide synchronously towards the center along the slide rail. At this time, the protrusions of the vertical plate precisely embed into the grooves of the sliders, restricting the two positioning blocks at both ends of the label roll. During subsequent unwinding, the vertical plate continuously suppresses the axial displacement of the positioning blocks through the constraint of the protrusions, achieving the effect of preventing label roll offset.

Description

Technical Field

[0001] This utility model relates to the technical field of testing devices for label production, specifically a testing device for label production that is easy to position. Background Technology

[0002] Label production inspection equipment is a device that performs real-time and automatic quality checks on the printed patterns on the label surface during the label winding process. The inspection equipment generally consists of a control console, an unwinding structure, guide rollers, and an inspection camera.

[0003] In existing label production inspection devices, the label roll is placed on the unwinding roller of the unwinding structure. The label strip released from the unwinding structure passes through a series of guide rollers and is finally wound onto an external winding device. As the label strip passes through the inspection area of ​​the inspection camera at a uniform speed and continuously under the traction of the external winding device, the camera continuously and at high speed captures images of the moving label surface. The inspection camera can capture each frame of the label pattern it passes through. Its internal image processing system analyzes the captured images in real time and compares them with preset standard patterns, thereby automatically identifying quality problems such as printing defects, content errors, and color deviations.

[0004] However, existing label rolls are simply fitted onto the unwinding roller, which itself lacks a reliable axial positioning structure. This design flaw causes the label roll to easily shift axially on the unwinding roller during equipment operation, especially during start-up, stopping, or speed changes. This offset directly disrupts the stability of the label tape's running path, preventing it from accurately and smoothly passing through the guide roller system and entering the detection area. This path deviation can not only cause the label tape to run off-track, wrinkle, or even break, but more importantly, it can cause positional shifts, distortions, or blurring in the images captured by the detection camera. This severely interferes with the recognition accuracy of the image processing system, ultimately leading to missed defects, false detections, or invalid detection results, directly affecting the quality control effect and reliability of the entire detection device. Utility Model Content

[0005] The purpose of this invention is to provide a label production detection device that is easy to position, and to solve the problem that during equipment operation, especially when starting, stopping or changing speed, the label roll is prone to axial movement on the unwinding roller, and the offset of the label roll will directly destroy the stability of the label tape running path.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a label production inspection device with easy positioning, comprising a control console. The upper surface of the control console is provided with an unwinding structure and a guide roller. A support frame is installed on one side of the control console, and an inspection camera is installed on the lower surface of the support frame. The unwinding structure includes a base plate, and the upper surface of the base plate is provided with two side plates. An unwinding roller is installed between the two side plates. A positioning component is provided on the outer surface of the unwinding roller. The positioning component includes a bidirectional screw, which is rotatably connected between the two side plates. Two sliders are threadedly connected to the outer surface of the bidirectional screw. The upper surface of the sliders is provided with a vertical plate. Two positioning blocks are slidably connected to the outer surface of the unwinding roller.

[0008] Furthermore, a protrusion is provided on one side of the vertical plate, and a groove is provided on the outer surface of the slider, with the protrusion fitted inside the groove.

[0009] Furthermore, a slide rail is installed on the upper surface of the base plate, and the slider is slidably connected to the outer surface of the slide rail. One of the side plates has a mounting seat on its outer surface, and a motor is installed on the upper surface of the mounting seat. The output end of the motor is installed to one end of a double-acting screw through a coupling.

[0010] Furthermore, a fixing block is provided at the upper end of the side plate, an installation groove is provided on the upper surface of the side plate, a connecting block is provided on the lower surface of the fixing block, the connecting block is fitted into the installation groove, and a limit groove is provided on one side of the connecting block.

[0011] Furthermore, a connecting frame is installed on the outer surface of the side plate, and an installation hole is formed on the outer surface of the connecting frame. A slide rod is slidably connected inside the installation hole. A baffle is installed at one end of the slide rod, and a pull block is installed at the other end of the slide rod. A limit block is installed on the outer surface of the baffle. One end of the limit block penetrates the side plate and is fitted inside the limit groove. A spring is sleeved on the outer surface of the slide rod. One end of the spring is installed on the outer surface of the baffle, and the other end of the spring is installed on the outer surface of the connecting frame.

[0012] Furthermore, an auxiliary groove is provided on the upper surface of the side plate, and an auxiliary block is provided on the lower surface of the fixing block. The auxiliary block is installed inside the auxiliary groove.

[0013] This utility model has the following beneficial effects:

[0014] (1) This utility model involves first placing the label roll into the unwinding roller, then having one end of it abut against one of the positioning blocks, and then moving the positioning block on the other side to fit against the other end of the label roll. The unwinding roller is then mounted on a vertical plate, and the motor is started to drive the bidirectional screw to rotate, causing the sliders on both sides to slide synchronously towards the center along the slide rail. At this time, the protrusions of the vertical plate are precisely embedded in the grooves of the sliders, restricting the two positioning blocks at both ends of the label roll. During the subsequent unwinding process, the vertical plate continuously suppresses the axial displacement of the positioning blocks through the constraint of the protrusions, thereby achieving the effect of preventing the label roll from shifting.

[0015] (2) When installing the fixing block of this utility model, align the connecting block with the mounting groove of the side plate and press it down vertically. When the tapered surface at the lower end of the connecting block contacts the limiting block, it generates a radial component force, which pushes the limiting block to move outward. Then, the sliding rod is driven by the baffle to slide to the outside of the connecting frame, which forces the spring to compress and store energy. When the connecting block is fully embedded in the mounting groove, the limiting block moves to the corresponding position of the limiting groove. At this time, the spring releases its elastic force to push the sliding rod to reset in the opposite direction, driving the limiting block to accurately lock into the limiting groove, forming a rigid mechanical lock, and realizing the quick fixing of the fixing block. By setting the fixing block, the unwinding roller can be fixed on the upper surface of the side plate, avoiding the phenomenon of the unwinding roller falling off the side plate during use.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0026] Please see Figures 1-5 As shown, this utility model is a label production detection device that is easy to position. It includes a control console 1. The upper surface of the control console 1 is provided with an unwinding structure 2 and a guide roller 3. A support frame 4 is installed on one side of the control console 1. A detection camera 5 is installed on the lower surface of the support frame 4. The unwinding structure 2 includes a base plate 201. The upper surface of the base plate 201 is provided with two side plates 202. An unwinding roller 203 is installed between the two side plates 202. The outer surface of the unwinding roller 203 is provided with a positioning component 6. The positioning component 6 includes a bidirectional screw 601. The bidirectional screw 601 is rotatably connected between the two side plates 202. The outer surface of the bidirectional screw 601 is threadedly connected with two sliders 602. The upper surface of the sliders 602 is provided with a vertical plate 603. The outer surface of the unwinding roller 203 is slidably connected with two positioning blocks 604.

[0027] The positioning component 6 can be set to quickly position the label roll in the middle of the unwinding roller 203. During the subsequent unwinding process, the axial displacement of the label roll is continuously suppressed by the constraint of the positioning component 6, so as to achieve the effect of preventing the label roll from shifting.

[0028] A protrusion 605 is provided on one side of the vertical plate 603, and a groove is provided on the outer surface of the slider 602, with the protrusion 605 fitted inside the groove.

[0029] A slide rail 606 is mounted on the upper surface of the base plate 201, and a slider 602 is slidably connected to the outer surface of the slide rail 606. A mounting base 204 is provided on the outer surface of one of the side plates 202, and a motor 607 is mounted on the upper surface of the mounting base 204. The output end of the motor 607 is mounted to one end of the bidirectional screw 601 through a coupling.

[0030] A fixing block 7 is provided at the upper end of the side plate 202. An installation groove 205 is provided on the upper surface of the side plate 202. A connecting block 701 is provided on the lower surface of the fixing block 7. The connecting block 701 is installed in the installation groove 205. A limit groove 702 is provided on one side of the connecting block 701. A tapered surface is provided at the lower end of the connecting block 701.

[0031] A connecting frame 8 is installed on the outer surface of the side plate 202. The outer surface of the connecting frame 8 has a mounting hole. A slide rod 9 is slidably connected inside the mounting hole. A baffle 10 is installed at one end of the slide rod 9, and a pull block 11 is installed at the other end of the slide rod 9. A limit block 12 is installed on the outer surface of the baffle 10. One end of the limit block 12 passes through the side plate 202 and is fitted inside the limit groove 702. A spring 13 is sleeved on the outer surface of the slide rod 9. One end of the spring 13 is installed on the outer surface of the baffle 10, and the other end of the spring 13 is installed on the outer surface of the connecting frame 8.

[0032] When installing the fixing block 7, align its connecting block 701 with the mounting groove 205 of the side plate 202 and press it down vertically. The conical surface at the lower end of the connecting block 701 generates a radial force when it contacts the limiting block 12, pushing the limiting block 12 to move outward. Then, through the baffle 10, the sliding rod 9 is driven to slide outward to the connecting frame 8, forcing the spring 13 to compress and store energy. When the connecting block 701 is fully embedded in the mounting groove 205, the limiting block 12 moves to the corresponding position of the limiting groove 702. At this time, the spring 13 releases its elastic force to push the sliding rod 9 to reset in the opposite direction, driving the limiting block 12 to accurately engage inside the limiting groove 702, forming a rigid mechanical lock, and realizing the rapid fixing of the fixing block 7. Through the fixed block 7, the unwinding roller 203 can be fixed on the upper surface of the side plate 202, preventing the unwinding roller 203 from falling off the side plate 202 during use.

[0033] The upper surface of the side plate 202 is also provided with an auxiliary groove, and the lower surface of the fixing block 7 is provided with an auxiliary block 703, which is installed inside the auxiliary groove.

[0034] In use, first, the label roll is placed onto the unwinding roller 203, and one end is placed against one of the positioning blocks 604. Then, the positioning block 604 on the other side is moved to fit the other end of the label roll. The unwinding roller 203 is then installed on the side plate 202. Next, the fixing block 7 is removed, and its connecting block 701 is aligned with the mounting groove 205 of the side plate 202 and pressed down vertically. When the tapered surface at the lower end of the connecting block 701 contacts the limiting block 12, it generates a radial force, pushing the limiting block 12 outward. This, in turn, drives the slide rod 9 to slide outward through the baffle 10, forcing the spring 13 to compress and store energy. When the connecting block 701 is fully embedded in the mounting groove 205, the limiting block 12 moves to the corresponding position in the limiting groove 702. At this time, the spring 13 releases its elastic force, pushing the slide rod 9 to reset in the opposite direction, driving the limiting block 12 to precisely engage inside the limiting groove 702, forming a rigid mechanical lock, thus achieving a quick and easy locking of the fixing block 7. After the unwinding roller 203 is fixed, the motor 607 is started to drive the bidirectional screw 601 to rotate, which drives the sliders 602 on both sides to slide synchronously towards the center along the slide rail 606. At this time, the protrusions 605 of the vertical plate 603 are precisely embedded in the grooves of the sliders 602, which restricts the two positioning blocks 604 at both ends of the label roll. Then, the label tape released from the unwinding structure 2 passes through a series of guide rollers 3 and is finally wound onto the external winding equipment. When the label tape passes through the detection area of ​​the detection camera 5 at a uniform speed and continuously under the traction of the external winding equipment, the camera will continuously and at high speed capture images of the moving label surface. The detection camera 5 can take pictures of each frame of the label pattern that passes by. Its internal image processing system will analyze the captured images in real time and compare them with the preset standard pattern, thereby automatically identifying quality problems such as printing defects, content errors, and color deviations.

[0035] When the label roll needs to be replaced, first start the motor 607 to drive the bidirectional screw 601 to rotate in the opposite direction, causing the sliders 602 on both sides to move outward synchronously along the slide rail 606. This causes the protrusion 605 of the vertical plate 603 to disengage from the groove of the slider 602. Then, pull the pull block 11 outward, which drives the baffle 10 to compress the spring 13 through the slide rod 9, forcing the limit block 12 to completely exit the limit groove 702. At this time, pull the fixing block 7 upward, and the connecting block 701 will then disengage from the mounting groove 205, releasing the constraint on the unwinding roller 203. Finally, vertically remove the unwinding roller 203, install the new label roll, and reset all components according to the reverse process to proceed to the next round of inspection.
