Description
Technical Field
[0001] This utility model relates to the field of wet wipe production technology, specifically a wet wipe packaging bag cap position detection device. Background Technology
[0002] In the production process of wet wipes, the packaging bag serves as a crucial carrier for product storage, protection, and display. The positional accuracy of its cap directly impacts the user experience and market competitiveness. Wet wipe packaging bags typically rely on the cap for sealing. If the cap shifts or misaligns after production and assembly, it not only causes inconvenience for consumers and reduces sealing performance (e.g., leading to moisture loss and bacterial growth in the wet wipes), but it may also result in the product being deemed defective due to aesthetic flaws, increasing rework costs and material waste for the company.
[0003] Currently, wet wipe production mostly adopts an assembly line operation mode, with conveyor belts as the core conveying equipment, which need to achieve continuous and efficient transfer of packaging bags. However, in the actual production process, due to the influence of multiple factors, the packaging bags are prone to positioning deviations, resulting in insufficient accuracy in detecting the position of the bag cap. Therefore, a wet wipe packaging bag cap position detection device is proposed to solve the above-mentioned problems. Utility Model Content
[0004] The purpose of this invention is to provide a wet wipe packaging bag cap position detection device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a wet wipe packaging bag cap position detection device, including two side plates, a conveyor belt between the two side plates, a frame on the side plates, a detection mechanism on the frame, the detection mechanism including a positioning component and a photoelectric sensor, the photoelectric sensor being slidably connected to the frame.
[0006] Preferably, the positioning component includes a motor, which is mounted on the frame. The output end of the motor is connected to a bidirectional threaded rod, which passes through the frame and is rotatably connected to the inner wall of the frame. A guide plate is threaded onto the bidirectional threaded rod.
[0007] Preferably, there are two guide plates, which are symmetrically arranged on the bidirectional threaded rod. A limiting groove is provided at the top of the frame, and a limiting block is provided at the top of the guide plate. The limiting block is slidably connected to the inner wall of the limiting groove, and a guide wheel is rotatably connected to the guide plate.
[0008] Preferably, a cylinder is installed on the top of the frame, a connecting rod is hinged to the output end of the cylinder, and the other end of the connecting rod is hinged to a photoelectric sensor. A slider is provided on the top of the photoelectric sensor, and a horizontal groove is opened on the top of the frame, with the slider slidingly connected to the inner wall of the horizontal groove.
[0009] Preferably, the frame is provided with a leveling mechanism, which includes an electric push rod. The electric push rod is installed on the top of the frame, and the output end of the electric push rod passes through the top of the frame and is equipped with a lifting frame. The inner wall of the lifting frame is slidably connected to a lifting plate.
[0010] Preferably, a telescopic rod is connected to the bottom of the lifting plate, a flat plate is connected to the bottom of the telescopic rod, a spring is sleeved on the outside of the telescopic rod, and the two ends of the spring are respectively connected to the bottom of the lifting plate and the top of the flat plate.
[0011] Preferably, a limiting plate is fixedly connected to the guide plate, and the inner wall of the limiting plate is slidably connected to the lifting plate.
[0012] The present invention adopts the above technical solution, which can bring the following beneficial effects: 1. This wet wipe packaging bag cap position detection device effectively solves the problem of poor positioning stability during packaging bag conveying through the synergistic effect of positioning components and photoelectric sensors. A motor-driven bidirectional threaded rod adjusts two guide plates symmetrically, enabling precise centering according to different packaging bag sizes and preventing lateral offset and tilting during conveying. Simultaneously, a cylinder drives a photoelectric sensor to slide along a transverse groove via a connecting rod, flexibly adapting to different bag caps. Combined with simultaneous detection of both sides of the bag cap by dual photoelectric sensors, it accurately identifies left-right offsets and misalignments, reducing the defect rate caused by cap position defects and minimizing rework costs and material waste for enterprises.
[0013] 2. This wet wipe packaging bag cap position detection device uses an electric push rod to drive a lifting frame to raise and lower a flat plate, which can be adjusted according to the height of the packaging bag. The combination design of the telescopic rod and spring allows the flat plate to form a flexible press when it contacts the top of the packaging bag, smoothing out the top wrinkles and protrusions, avoiding wrinkles from blocking the detection light path or being misidentified as the edge of the bag cap, ensuring that the photoelectric sensor always detects the flat bag cap area, and further improving the accuracy and stability of the detection results.
[0014] 3. This wet wipe packaging bag cap position detection device, through a signal connection between a photoelectric sensor and an electric push rod, can automatically trigger the electric push rod to drive a push plate to push the cap onto a slide rail for rejection when a defective product is detected, eliminating the need for manual screening. This avoids the problems of low efficiency and easy omissions in manual inspection, reduces labor costs, and achieves automated integration of cap detection and defective product handling in wet wipe production, meeting the high-efficiency production needs of modern assembly lines.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0018] Please see Figure 1-4 One embodiment of this utility model is: a wet wipe packaging bag cap position detection device, including two side plates 1, a conveyor belt between the two side plates 1, a frame 2 on the side plates 1, and a detection mechanism 3 on the frame 2.
[0019] The detection mechanism 3 includes a positioning component and two photoelectric sensors 37. These two sensors detect the left and right sides of the packaging bag cap. The two sensors 37 are symmetrically arranged on the frame 2. The positioning component includes a motor 31 mounted on the frame 2. The output end of the motor 31 is connected to a bidirectional threaded rod 32, which penetrates the frame 2 and is rotatably connected to the inner wall of the frame 2. Two guide plates 33 are threaded onto the bidirectional threaded rod 32, symmetrically arranged on it. A limit groove is formed at the top of the frame 2. A limiting block is provided at the top, and the limiting block is slidably connected to the inner wall of the limiting groove. A guide wheel 34 is rotatably connected to the guide plate 33. The design of the guide wheel 34 can reduce the contact resistance with the packaging bag, so that the packaging bag can move stably and will not get stuck due to excessive resistance. The front ends of the two guide plates 33 are tilted outward to facilitate better positioning of the packaging bag. A cylinder 35 is installed at the top of the frame 2. A connecting rod 36 is hinged to the output end of the cylinder 35, and the other end of the connecting rod 36 is hinged to the photoelectric sensor 37. A slider 39 is provided at the top of the photoelectric sensor 37. A transverse groove 38 is opened at the top of the frame 2, and the slider 39 is slidably connected to the inner wall of the transverse groove 38.
[0020] An electric push rod is provided on the side plate 1. The output end of the electric push rod is fixedly connected to the push plate 5. The electric push rod is connected to the photoelectric sensor 37. A slide rail 6 is provided on one side of the side plate 1. The electric push rod, push plate 5 and slide rail 6 are provided to facilitate the removal of unqualified packaging bags from the conveyor belt.
[0021] Working principle: The starting motor 31 drives the bidirectional threaded rod 32 to rotate. The rotation of the bidirectional threaded rod 32 will drive the two guide plates 33 to move relative to each other. Adjustment is made according to the size of the wet wipe packaging bag. At the same time, the cylinder 35 is started. The cylinder 35 drives one end of the connecting rod 36 to move. Under the action of the transverse groove 38 and the slider 39, the photoelectric sensor 37 is moved. Adjustment is made according to the size of the bag cap so that the two photoelectric sensors 37 are positioned on both sides above the bag cap.
[0022] The wet wipe packaging bags are conveyed by a conveyor belt. When the wet wipe packaging bag moves to the guide plate 33, the inclined surface of the guide plate 33 moves the packaging bag towards the center, thereby achieving the positioning of the packaging bag. Then, the photoelectric sensor 37 detects the bag cap. When the bag cap shifts to the left, the left photoelectric sensor 37 detects the bag cap first, and the right photoelectric sensor 37 detects it later. When the bag cap shifts to the right, the right photoelectric sensor 37 detects the bag cap first, and the left photoelectric sensor 37 detects it later. At this time, the signal is transmitted to the electric push rod, which drives the push plate 5 to push the packaging bag onto the slide 6, thereby rejecting the unqualified packaging bag on the conveyor belt. When both photoelectric sensors 37 detect the bag cap at the same time, the push plate 5 at the rear does not move, so that the qualified packaging bag continues to be conveyed on the conveyor belt.
[0023] Please see Figure 1-4 Based on the above embodiments, in another embodiment of the present invention, a leveling mechanism 4 is provided on the frame 2. The leveling mechanism 4 includes an electric push rod 41, which is installed on the top of the frame 2. The output end of the electric push rod 41 passes through the top of the frame 2 and is fitted with a lifting frame 42. A lifting plate 43 is slidably connected to the inner wall of the lifting frame 42. A telescopic rod 44 is connected to the bottom of the lifting plate 43. A leveling plate 45 is connected to the bottom of the telescopic rod 44. A spring 46 is sleeved on the outside of the telescopic rod 44. The two ends of the spring 46 are respectively connected to the bottom of the lifting plate 43 and the top of the leveling plate 45. A limiting plate 47 is fixedly connected to the guide plate 33. The inner wall of the limiting plate 47 is slidably connected to the lifting plate 43.
[0024] Working principle: By activating the electric push rod 41, the electric push rod 41 drives the lifting frame 42 to rise and fall. The rise and fall of the lifting frame 42 drives the lifting plate 43 to rise and fall, which in turn drives the flat plate 45 to rise and fall through the telescopic rod 44. The height of the flat plate 45 is adjusted according to the height of the packaging bag so that the height of the packaging bag is slightly lower than the height of the packaging bag. When the packaging bag moves below the photoelectric sensor 37, the top of the packaging bag is smoothed by the flat plate 45, so that the top of the packaging bag passes through the flat plate 45 flat, thereby avoiding unevenness of the top of the packaging bag, which would affect the detection results.
[0025] This utility model provides a wet wipe packaging bag cap position detection device. There are many methods and approaches to implement this technical solution. The above description is only a 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. All components not explicitly stated in this embodiment can be implemented using existing technology.
