Description

Technical Field

[0001] This utility model relates to the field of ranging equipment technology, specifically to a visual ranging device for a small rewinding machine. Background Technology

[0002] Packaging bags are bags used to package various daily necessities, making it easy to transport and store goods during the production and distribution process. A rewinding machine is a mechanical device that can rewind long, thin materials such as films, packaging bags, or toilet paper that are wound on large rolls onto small rolls. Rewinding machines can be used for rewinding toilet paper, adhesive tape, and plastic film, etc.

[0003] If the original roll of the thin-film plastic packaging bag is loose after production, it is not suitable for direct sale. Therefore, it is necessary for staff to stand next to the equipment to check the roll effect. However, due to visual fatigue or difficulty in maintaining concentration, the roll may become loose or the pattern on the packaging bag may shift, affecting the quality of the packaging bag. In severe cases, it may even cause the packaging bag to be scrapped, reducing production efficiency and causing unnecessary economic losses. Utility Model Content

[0004] In view of this, the present invention provides a small visual ranging device for rewinding machines, which can collect and compare the patterns on the packaging bags being wound by the rewinding machine through the acquisition module, greatly improving the accuracy and efficiency of the detection and increasing production efficiency.

[0005] To address the aforementioned technical problems, this utility model provides a small visual ranging device for a rewinding machine. It includes a mounting frame on the frame of the rewinding machine, a visual ranging mechanism mounted on the mounting frame, a vertical frame on the frame, and a horizontal frame on the vertical frame. The visual ranging mechanism includes dustproof boxes at both ends of the horizontal frame. Each dustproof box contains an adjustment component, and each adjustment component contains a data acquisition module. The adjustment component can adjust the height and angle of the data acquisition module. This utility model allows the rewinding machine to collect and compare patterns on the rewound packaging bags by adjusting the position of the data acquisition module. This enables timely detection of patterns on the packaging bags that may shift, significantly reducing the impact on packaging bag quality caused by visual fatigue or difficulty maintaining focus during traditional manual inspection. In severe cases, this can even lead to production waste, reduced production efficiency, and unnecessary economic losses.

[0006] The adjustment assembly includes a telescopic push rod installed inside the mounting box. A fixed plate is installed at the end of the output rod of the telescopic push rod. A rotating shaft is installed on the fixed plate. A fixing component is rotatably installed on the outside of the rotating shaft. The acquisition module is installed at the lower part of the fixed frame.

[0007] The inner wall of the mounting box is provided with a guide rail. The guide rail and the telescopic push rod are respectively located on two adjacent side walls inside the mounting box. A driving component is slidably arranged inside the guide rail. The output shaft of the driving component is connected to the housing of the acquisition module.

[0008] Sealing baffles are installed on the bottom two side walls of the mounting box by means of torsion springs. When the two sealing baffles are horizontal, they can block and close the bottom of the mounting box.

[0009] The acquisition module is a surveillance camera with video recording function.

[0010] The telescopic push rod can be an electric telescopic rod or a hydraulic telescopic rod.

[0011] The driving component is a servo motor.

[0012] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0013] 1. This utility model can replace traditional manual visual inspection with a visual ranging mechanism, which is more efficient and greatly improves the accuracy and efficiency of detection.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0023] like Figure 1-4 As shown: This embodiment provides a small rewinding machine visual ranging device, including a mounting frame 200 mounted on the frame 100 of the rewinding machine, a visual ranging mechanism 300 mounted on the mounting frame 200, and a controller electrically connected to the visual ranging mechanism 300. The controller is a Siemens brand. The mounting frame 200 includes a vertical frame 201 mounted on the frame 100 and a horizontal frame 202 mounted on the vertical frame 201. The visual ranging mechanism 300 includes dustproof boxes 310 mounted at both ends of the horizontal frame 202. Figure 1 As shown, there are two dust boxes 310, each equipped with an adjustment component 320. Each adjustment component 320 is equipped with a data acquisition module 400. The adjustment component 320 can adjust the height and angle of the data acquisition module 400. This invention can adjust the position of the data acquisition module 400 by adjusting the adjustment component 320 to collect and compare the pattern on the packaging bag being wound by the rewinding machine. This allows for timely detection of issues such as pattern deviation on the packaging bag, greatly reducing the problems associated with traditional manual inspection relying on the naked eye. These issues can lead to problems such as loose winding of the roll or pattern deviation on the packaging bag, which can affect the quality of the packaging bag and, in severe cases, even cause the packaging bag production to be scrapped, reducing production efficiency and causing unnecessary economic losses.

[0024] According to one embodiment of the present invention, such as Figure 1-2 As shown, the adjustment component 320 includes a telescopic push rod 321 installed inside the mounting box. A fixing plate 322 is provided at the output rod end of the telescopic push rod 321. A rotating shaft 323 is provided on the fixing plate 322. A fixing member 324 is rotatably provided on the outer side of the rotating shaft 323. The acquisition module 400 is located at the lower part of the fixed frame. The acquisition module 400 is a surveillance camera with video recording function, and its brand is Xiaomi. This utility model can adjust the height of the acquisition module 400 by extending and retracting the output rod of the telescopic push rod 321, thereby realizing convenient and quick adjustment of the acquisition range of the acquisition module 400, making the operation more convenient.

[0025] According to another embodiment of the present invention, such as Figure 1 and Figure 3 As shown, a guide rail 500 is provided on the inner side wall of the mounting box. The guide rail 500 and the telescopic push rod 321 are respectively located on two adjacent side walls inside the mounting box. A drive component 600 is slidably arranged inside the guide rail 500. The output shaft of the drive component 600 is connected to the housing of the acquisition module 400. This utility model can adjust the angle of the acquisition module 400 by rotating the output shaft of the drive component 600, and cooperate with the mounting box to achieve protective operation of the acquisition module 400.

[0026] Sealing baffles 700 are respectively installed on the bottom two side walls of the mounting box by means of torsion springs. When the two sealing baffles 700 are horizontal, they can block and close the bottom of the mounting box. This utility model can achieve the sealing and blocking of the bottom of the mounting box by means of torsion springs, so as to prevent dust from entering the sealed box and adhering to the acquisition module 400, which would affect the normal acquisition work of the acquisition module 400.

[0027] According to another embodiment of the present invention, such as Figure 1 and Figure 4 As shown, the telescopic push rod 321 is an electric telescopic rod or a hydraulic telescopic rod. This utility model can push the monitoring camera downward by extending the output rod of the telescopic push rod 321, while simultaneously pushing the sealing baffle 700 downward under the action of the torsion spring, so that the monitoring camera is exposed, thus enabling the monitoring of the rewinding machine.

[0028] The drive unit 600 is a servo motor. This utility model can rotate the monitoring camera to a certain angle by rotating the output shaft of the servo motor, thereby rotating the camera into the protective cover set on the inner wall of the protective box, thus achieving effective protection of the monitoring camera.

[0029] How to use this utility model:

[0030] First, it needs to be clarified that the visual ranging device involved in this utility model is mainly used for real-time detection, analysis and comparison of patterns on packaging bags and the winding status of packaging bags during the rewinding process. This utility model takes the real-time detection of pattern position gauges on traditional Chinese medicine packaging bags as an example to describe its usage method in detail. When it is necessary to detect the pattern on the packaging bag, the output rod of the telescopic push rod 321 is extended. The extension of the output rod of the telescopic push rod 321 pushes the monitoring camera downward and simultaneously pushes the sealing baffle 700 to rotate downward under the action of the torsion spring until the monitoring camera is exposed, so that the status of the rewinding machine can be monitored. When the patterns detected by the two monitoring cameras are significantly different or the pattern spacing is obviously inconsistent, the controller will control the rewinding machine to stop working, and maintenance personnel can then resume the rewinding operation after inspection and maintenance. This utility model can realize the acquisition and comparison of patterns on the winding packaging bags by the rewinding machine through the acquisition module 400, which greatly improves the accuracy and efficiency of detection and improves production efficiency.

[0031] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
