Description

Technical Field

[0001] This utility model relates to the field of turnover box cleaning technology, and in particular to a turnover box cleaning mechanism. Background Technology

[0002] Turnover boxes, also known as turnover baskets, are common containers used for logistics transfer and temporary storage in warehousing and logistics production processes. Plastic turnover boxes are widely used due to their lightweight, durability, and low cost. However, these boxes face the problem of being difficult to clean after becoming dirty. Especially for plastic turnover boxes with perforated structures, dirt easily accumulates in the perforated areas when used in food processing and storage, and the special structure significantly increases the difficulty of cleaning. Furthermore, after food is placed inside the turnover boxes, residual food scraps, oil stains, and dust are difficult to completely remove. Manual cleaning requires first manually emptying the residue, and then using tools such as cloths, brushes, and spray guns to clean the turnover boxes, a cumbersome, time-consuming, and labor-intensive process.

[0003] In the prior art, Chinese patent CN118106311A discloses a cleaning machine for turnover boxes. This solution involves feeding the turnover box face up into the machine frame via a first conveyor, flipping it over by a 180-degree flipping mechanism to empty dust and other debris; then, face down, it enters a spray cleaning mechanism to complete internal and external spray cleaning; next, the face-up back is brushed, and then the water on the back is emptied by a first 360-degree flipping mechanism, continuing to face down for a first spray rinsing, side brushing, and a second spray rinsing; finally, the second 360-degree flipping mechanism flips it once or multiple times to shake off the accumulated water, and then the box is dried by air cutting to complete the cleaning process.

[0004] Regarding the aforementioned technology, this solution mainly targets the external cleaning of turnover boxes, and is not very effective at cleaning stubborn dirt inside some turnover boxes. In addition, the supply speed of turnover boxes on the conveyor line exceeds the processing capacity of the box cleaning machine. The number of turnover boxes arriving at the box cleaning machine per unit time is too large, and the box cleaning machine cannot complete the cleaning in time, which easily causes turnover boxes to accumulate on the conveyor belt. Utility Model Content

[0005] To address the problems of poor internal cleaning effect and easy accumulation of turnover boxes during the conveying process in existing turnover box cleaning equipment, this utility model provides a turnover box cleaning mechanism that can clean the inside of the turnover boxes, improve the cleanliness of the turnover boxes, and prevent turnover boxes from accumulating on the conveying line.

[0006] To achieve the above objectives, the following technical solution is provided:

[0007] A turnover box cleaning mechanism includes a first conveying platform, a first scrubbing platform located above the first conveying platform, and a controller. The first scrubbing platform includes a first frame, a first rotary motor, and a lifting mechanism for controlling the up and down movement of the first rotary motor. A first roller brush is driven and connected below the first rotary motor. A first sensor, a second sensor, and a third sensor are sequentially arranged along the conveying direction on the first conveying platform below the first scrubbing platform. The distance between the first sensor and the third sensor is greater than the horizontal length of the turnover box to be scrubbed, and the distance between the second sensor and the third sensor is less than the horizontal length of the turnover box to be scrubbed. The displacement sensor, the lifting mechanism, the first sensor, the second sensor, and the third sensor are all electrically connected to the controller.

[0008] Furthermore, the first scrubbing platform also includes a first spray device.

[0009] Furthermore, the first conveying platform is equipped with a displacement sensor for detecting the conveying distance, and the displacement sensor is electrically connected to the controller.

[0010] Furthermore, on the first conveying platform, a flipping mechanism is provided at both the front and rear ends of the first frame. The flipping mechanism includes a flipping bracket and a flipping motor for controlling the rotation of the flipping bracket. A fourth sensor for detecting the position of the flipping bracket is provided on the front side of the flipping motor.

[0011] Furthermore, a fifth sensor is provided on the front side of the flipping motor to detect that the turnover box to be washed is located on the flipping mechanism.

[0012] Furthermore, a second conveyor platform and a third conveyor platform are respectively provided at the front end and the rear end of the first conveyor platform, and an outer frame cleaning device and a cleaning and drying device are respectively provided on the second conveyor platform and the third conveyor platform.

[0013] Furthermore, the outer frame cleaning device includes a second frame and a second spray device. The second mechanism has a second roller brush on both sides and a second motor for controlling the rotation of the second roller brush. A third roller brush is arranged horizontally above the second mechanism. The distance between the two second roller brushes matches the width of the turnover box to be cleaned, and the height of the third roller brush matches the height of the turnover box to be cleaned.

[0014] Furthermore, the cleaning and drying device includes a third frame, inside which a third spraying device and drying equipment are installed.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This solution adds a cleaning process for the inside of the turnover box. The first roller brush can be inserted into the turnover box by lifting and lowering to scrub the dirt inside the turnover box, which helps to improve cleaning efficiency and effect.

[0017] 2. Through the coordination of the first sensor, the second sensor, the third sensor, and the sprocket displacement on the first conveying platform with the controller, it can ensure that the conveyed turnover boxes are cleaned by the first roller brush in sequence, avoiding the accumulation of turnover boxes during the conveying process; it has the characteristics of high automation and high production efficiency.

[0018] 3. In this solution, an outer frame cleaning device and a cleaning and drying mechanism are respectively installed at both ends of the first conveyor platform. The second roller brush on the second conveyor platform is used to brush the sides of the turnover box, and the third roller brush is used to brush the bottom of the turnover box. After the turnover box is turned upward by the flipping mechanism, the inside of the turnover box is brushed. Finally, it is conveyed to the cleaning and drying mechanism to clean and dry the turnover box. Attached Figure Description

[0026] The following detailed description of a turnover box cleaning mechanism of this utility model is provided with reference to specific embodiments.

[0027] It should be noted that, with the outer frame cleaning device located in the front and the cleaning and drying device located in the back, the conveyor platform moves backward.

[0028] A turnover box cleaning mechanism includes a first conveying platform 1, a first scrubbing platform located above the first conveying platform 1, and a controller. The first conveying platform 1 is equipped with a displacement sensor 2 for detecting the conveying distance. The first scrubbing platform includes a first frame 3, a first spraying device 4, a first rotary motor 5, and a lifting mechanism 6 for controlling the up and down movement of the first rotary motor 5. A first roller brush 7 is driven and connected below the first rotary motor 5. A first sensor 8, a second sensor 9, and a third sensor 10 are sequentially arranged on the first conveying platform 1 below the first scrubbing platform along the conveying direction. The distance between the first sensor 8 and the third sensor 10 is greater than the horizontal length of the turnover box 25 to be scrubbed, and the distance between the second sensor 9 and the third sensor 10 is less than the horizontal length of the turnover box 25 to be scrubbed. The displacement sensor 2, the lifting mechanism 6, the first sensor 8, the second sensor 9, and the third sensor 10 are all electrically connected to the controller.

[0029] In this embodiment, the first conveying platform 1 is a chain conveyor belt, which is connected to the conveyor motor 27 via a chain 26 to generate driving force. A displacement sensor 2 is installed on the transmission path of the chain 26 to ensure that the sensor can accurately detect the movement of the chain 26. Alternatively, the sensor can be installed near the sprocket of the chain 26 to indirectly measure the conveying distance of the chain 26 by detecting the rotation angle of the sprocket. For example, an angular displacement sensor 2 can be connected to the shaft of the sprocket; when the sprocket rotates, the sensor can monitor the rotation angle of the shaft in real time and convert it into an electrical signal output.

[0030] Before cleaning the inside of the turnover box 25, the turnover box 25 is flipped by the flipping mechanism so that the opening faces upward. The specific cleaning process is as follows:

[0031] In the initial state, such as Figure 1 As shown, the first roller brush 7 is positioned above the height of the turnover box 25. When the first turnover box 25 moves with the first conveyor platform 1, as... Figure 2As shown, when the rear end of the first turnover box 25 reaches the third sensor 10, because the distance between the second sensor 9 and the third sensor 10 is less than the horizontal length of the turnover box 25 to be cleaned, the first turnover box 25 blocks the signals of the second sensor 9 and the third sensor 10. Based on the signal feedback from the second sensor 9 and the third sensor 10, the controller controls the lifting motor, the first rotary motor 5, and the first spray device 4 (the first spray device 4 can also be normally open) to start, and the first conveying platform 1 stops conveying. The lifting motor drives the first roller brush 7 to move downwards along the lifting guide rail 30, extending the first roller brush 7 into the interior of the turnover box 25, and using the action of the bristles to clean the dirt inside the turnover box 25. That is, during this process, the third sensor 10 is installed at the brushing start position, which can control the descent of the first brush.

[0032] When the second turnover box 25 enters the first conveyor platform 1, its rear end reaches the position of the first sensor 8, blocking the signal from the first sensor 8. The controller then stops the first roller brush 7, and the first conveyor platform 1 continues to move forward. When the front end of the first turnover box 25 leaves the position of the second sensor 9, the second sensor 9 is no longer blocked. The controller then raises the first roller brush 7 to its original position to prevent it from obstructing the second turnover box 25 from entering the washing position. Next, the second turnover box 25 reaches the position of the third sensor 10, blocking the signals from both the second and third sensors 9. The first brush descends, repeating the washing action.

[0033] In this embodiment, as Figure 4 As shown, there are two sets of first roller brushes 7 arranged vertically, capable of simultaneously brushing the inner wall of the turnover box 25. A guide rod 29 is installed between the two sets of first roller brushes 7. The front end of the guide rod 29 is raised to limit the turnover box 25 as it enters the brushing position, preventing it from swaying up and down with the first roller brushes during the brushing process. Specifically, the first roller brush 7 uses nylon bristles with a diameter of 200mm and a rotation speed of 200rpm. The frictional force generated by the first roller brush 7 on the turnover box is less than the conveying force of the conveyor platform. After the first roller brush 7 descends, it contacts the bottom of the turnover box. The two sets of first roller brushes 7 rotate in opposite directions, both in the conveying direction; the distance between the outer edges of the two sets of first roller brushes 7 matches the inner wall of the turnover box.

[0034] In this embodiment, as Figure 1 , Figure 2 , Figure 3As shown, on the first conveyor platform 1, both the front and rear ends of the first frame 3 are equipped with flipping mechanisms. Each flipping mechanism includes a flipping bracket 11 and a flipping motor 12 that controls the rotation of the flipping bracket 11. A fourth sensor 13 for detecting the position of the flipping bracket 11 is located on the front side of the flipping motor 12. There are three sets of flipping brackets 11 arranged in a windmill shape. Each set of flipping brackets 11 has two flipping trays located on both sides of the first conveyor platform 1. Limit plates are provided on the flipping trays. When a turnover box 25 enters a flipping tray, it is blocked by the limit plate. Then, the flipping motor 12 drives the flipping bracket 11 to rotate, flipping the turnover box 25 so that it can be cleaned in the next process. The fourth sensor 13 is connected to a controller and is used to detect the position of the flipping bracket 11, such as whether the two flipping trays have reached the flipping position, in order to achieve precise process control.

[0035] Preferably, the front side of the flipping motor 12 is also provided with a fifth sensor 14 for detecting that the turnover box 25 to be washed is located on the flipping mechanism. The fifth sensor 14 is a proximity switch for detecting whether the flipping mechanism can be flipped. After the turnover box 25 to be washed enters the flipping tray, the fifth sensor 14 is triggered, and the controller controls the flipping motor 12 to start, flipping the turnover box 25.

[0036] The first frame 3 has a front-end flipping mechanism that flips the turnover box 25 so that the opening faces upward, facilitating the first roller brush 7 to clean the inside of the turnover box 25. The rear-end flipping mechanism of the first frame 3 performs a secondary flip, turning the turnover box 25 so that the opening faces downward, allowing the washed water and dirt to be poured out, and preparing for subsequent cleaning and drying. The fourth sensor 13 and fifth sensor 14 corresponding to the rear-end flipping mechanism of the first frame 3 function the same as those corresponding to the front-end flipping mechanism.

[0037] Better, such as Figure 5 As shown, a second transmission platform 15 and a third transmission platform 16 are respectively provided at the front end and rear end of the first transmission platform 1, and the second transmission platform 15 and the third transmission platform 16 are connected to the first transmission platform 1.

[0038] The second conveyor platform 15 and the third conveyor platform 16 are respectively equipped with an outer frame cleaning device and a cleaning and drying device. The outer frame cleaning device includes a second frame 17 and a second spray device 18, the second spray device 18 being a spray pipe installed inside the second frame 17. The second mechanism has second roller brushes 19 on both sides and a second motor 20 for controlling the rotation of the second roller brushes 19; a third roller brush 21 is horizontally arranged at the top inside the second mechanism; the distance between the two second roller brushes 19 matches the width of the turnover box 25 to be cleaned, and the height of the third roller brush 21 matches the height of the turnover box 25 to be cleaned.

[0039] The cleaning and drying device includes a third frame 22, inside which is a third spray device 23 and a drying device 24. The third spray device 23 is a spray pipe installed inside the third frame 22, which is connected to an external high-pressure water pipe. The drying device 24 is a hot air blower used to dry the cleaned turnover box 25.

[0040] A housing 28 is also provided on the outside of the first frame 3, the second frame 17 and the third frame 22, so that the cleaning work is carried out in a closed space.
