Description

Technical Field

[0001] This invention relates to the field of industrial cleaning machines, and in particular to a cleaning machine for turnover boxes. Background Technology

[0002] To facilitate the placement and turnover of items, multiple isolated storage slots are designed in the turnover box, allowing items to be placed individually in each slot, avoiding collisions and making it safer to use.

[0003] The numerous storage slots on the front of the turnover boxes increase the difficulty of cleaning them. Furthermore, since most turnover boxes are made of plastic, reinforcing ribs are added to the edges or center of the back to improve structural strength. These ribs form grooves, further increasing the difficulty of cleaning and requiring the boxes to be flipped during the cleaning process. A utility model patent with application number 202221031545.5 discloses a flipping and conveying mechanism for cleaning turnover boxes, which uses an arc-shaped guide rail to flip the boxes. However, it can only achieve a 180° flip, and its bulky structure makes it unsuitable for repeated use, resulting in an excessively large cleaning machine. Improvements are needed.

The first wind-cutting mechanism is located above the second 360-degree tilting mechanism, and the second wind-cutting mechanism is located on both sides and above the second conveyor frame.

[0006] In a preferred embodiment of the present invention, the frame is provided with rollers at horizontal intervals corresponding to the 180-degree flipping mechanism, the spray cleaning mechanism, the top brushing mechanism, the first spray rinsing mechanism, the side brushing mechanism, and the second spray rinsing mechanism.

[0007] In a preferred embodiment of the present invention, the frame is provided with a push rod conveying mechanism located on one or both sides of the 180-degree flipping mechanism, the spray cleaning mechanism, the top surface brushing mechanism, the first 360-degree flipping mechanism, the first spray rinsing mechanism, the side brushing mechanism, the second spray rinsing mechanism, and the second 360-degree flipping mechanism.

[0008] In a preferred embodiment of the present invention, the push rod conveying mechanism includes a chain and push rods spaced apart on the chain. The push rods extend horizontally along the width of the frame, and the interval between two adjacent push rods on the chain is greater than the length of the turnover box.

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-4 The embodiments of the present invention include:

[0023] like Figure 1 The turnover box cleaning machine shown is used for automatic cleaning of turnover boxes. It includes: a frame 1, a first conveyor frame 2, a 180-degree flipping mechanism 3, a spray cleaning mechanism 4, a top surface brushing mechanism 5, a first 360-degree flipping mechanism 6, a first spray rinsing mechanism 8, a side brushing mechanism 9, a second spray rinsing mechanism 10, a second 360-degree flipping mechanism 7, a first air cutting mechanism 15, a second conveyor frame 14, and a second air cutting mechanism 16. The first conveyor frame 2 is located at the front end of the frame 1 and sends the turnover box 13 into the frame 1.

[0024] The 180-degree flipping mechanism 3, the spray cleaning mechanism 4, the top surface brushing mechanism 5, the first 360-degree flipping mechanism 6, the first spray rinsing mechanism 8, the side brushing mechanism 9, the second spray rinsing mechanism 10, the second 360-degree flipping mechanism 7, and the second conveyor frame 14 are arranged sequentially and alternately in the frame 1. In this embodiment, the frame 1 is horizontally spaced with rollers corresponding to the 180-degree flipping mechanism 3, the spray cleaning mechanism 4, the top surface brushing mechanism 5, the first spray rinsing mechanism 8, the side brushing mechanism 9, and the second spray rinsing mechanism 10, which roll to support the transfer of the turnover box 13, resulting in high stability.

[0025] The frame 1 is equipped with a push rod conveying mechanism located on one or both sides of the 180-degree flipping mechanism 3, the spray cleaning mechanism 4, the top brushing mechanism 5, the first 360-degree flipping mechanism 6, the first spray rinsing mechanism 8, the side brushing mechanism 9, the second spray rinsing mechanism 10, and the second 360-degree flipping mechanism 7, to push and transfer the turnover box 13.

[0026] In this embodiment, the push rod conveying mechanism includes a chain 11 and push rods 12 spaced apart on the chain 11. The push rods 12 extend horizontally along the width direction of the frame 1, and the interval between two adjacent push rods 12 on the chain 11 is greater than the length of the turnover box 13. A sprocket that drives the chain 11 to rotate and a servo motor that drives the sprocket to rotate can be installed in the frame 1 to realize the intermittent movement of the chain 11. The push rods 12 extend to the tail of the turnover box 13 to push it forward, resulting in high displacement accuracy.

[0027] like Figure 1 and Figure 2 As shown, the 180-degree flipping mechanism includes a lifting platform 31, a first telescopic cylinder 33, a rotary cylinder 34, and a turnover box clamp 35. The first telescopic cylinder 33 is symmetrically arranged on both sides above the lifting platform 31. In this embodiment, the frame 1 is provided with a second telescopic cylinder 32 to drive the lifting platform 31 to move up and down, thereby driving the lifting platform 31 to move up and down and causing the turnover box 13 above the lifting platform 31 to move up and down, which is beneficial for raising the position of the turnover box 13 before flipping it.

[0028] A rotary cylinder 34 is horizontally positioned at the front end of the first telescopic cylinder 33, and a turnover box clamp 35 is positioned at the front end of the rotary cylinder 34. After the turnover box 13 rises, the first telescopic cylinder 33 drives the rotary cylinder 34 and the turnover box clamp 35 to move forward, clamping the turnover box 13. In this embodiment, a slot is provided on the side of the turnover box 13, and a corresponding locking block is provided on the turnover box clamp 35 to improve clamping stability. After the turnover box 13 is clamped, the rotary cylinder 34 rotates 180 degrees to empty the dust and other debris from the turnover box 13. Then, the turnover box 13 is sent face down to the spray cleaning mechanism 4 for internal and external spray cleaning, and the back of the turnover box facing upwards is brushed after cleaning.

[0029] In this embodiment, the top surface washing mechanism 5 includes a lifting platform 51 and a horizontal brush roller 52. The horizontal brush roller 52 is rotatably and horizontally mounted on the lifting platform 51. The lifting platform 51 is used to raise and lower the horizontal brush roller 52 to adapt to the height of different batches of turnover boxes, so that the bottom of the horizontal brush roller 52 contacts the upward-facing back of the turnover box. The horizontal brush roller 52 is driven to rotate by a motor to achieve the washing of the back of the turnover box.

[0030] After the top-facing back of the turnover box is washed, it needs to be fed into the first 360-degree flipping mechanism 6 to shake out the residual water inside and outside the turnover box. In this embodiment, the first 360-degree flipping mechanism 6 and the second 360-degree flipping mechanism 7 respectively include a first rotating shaft 61, a second rotating shaft 62, a flipping frame 67, a guide rail 72, and a locking rod 68. The first rotating shaft 61 is horizontally distributed along the width direction of the frame, and the two flipping frames 67 are spaced apart along the length direction of the first rotating shaft 61. The guide rail 72 is set on the flipping frame 67, and the spacing of the guide rail 72 on the two flipping frames 67 corresponds to the width of the turnover box 13, so that the turnover box 13 can stay on the guide rail 72 of the two flipping frames 67. The guide rail 72 can be made of L-shaped angle steel, which has a good limiting effect on both sides of the turnover box 13.

[0031] like Figure 3 and Figure 4 As shown, two pin seats 69 are spaced apart on the outer side of the guide rail 72. The locking rod 68 is vertically positioned within the pin seats 69, allowing for flexible inward and outward rotation. A spring 71 is provided in the pin seat 69 or the flipping frame 67 to drive the lower part of the locking rod 68 outward. A locking tongue 70, bent and extended inward from the top of the locking rod 68, is provided. After the turnover box 13 enters the guide rails 72 on both sides, it is locked by inserting the locking tongue 70 into the corresponding locking hole structure on both sides of the turnover box 13. After the turnover box 13 is fed onto the guide rails 72 on both sides by the push rod conveying mechanism, the push rod conveying mechanism rotates in the opposite direction a certain distance without affecting the rotation of the turnover box 13.

[0032] In this embodiment, a reduction motor 73 is provided in the frame 1 to drive the first rotating shaft 61 to rotate, thereby enabling the turnover box 13 to rotate 360 ​​degrees in a single or multiple rotations and shake off the residual water inside and outside the turnover box 13.

[0033] To unlock, the second rotating shaft 62 is arranged parallel to one side of the first rotating shaft 61. In this embodiment, a connecting rod 63 is provided at one end of the second rotating shaft 62, and a third telescopic cylinder 64 is provided in the frame 1 to drive the connecting rod 63 to swing, so as to realize the fixed angle rotation of the second rotating shaft 62.

[0034] A swing arm 66 is provided on the second rotating shaft 62, corresponding one-to-one with the guide rail 72 and extending below the guide rail 72. The swing arm 66 is provided with an unlocking block 65 corresponding one-to-one with the locking rod 68. The outer bottom of the locking rod 68 is provided with a chamfered surface 74 corresponding to the unlocking block 65. The rotation of the second rotating shaft 62 drives the swing arm 66 to swing upwards. The contact between the unlocking block 65 and the chamfered surface 74 drives the outer bottom of the locking rod 68 to move inwards, forcing the locking tongue 70 to move outwards, thereby unlocking the turnover box 13. Figure 4 As shown, the turnover box 13 can be continuously pushed by the push rod conveying mechanism.

[0035] After the turnover box 13 undergoes its first 360° flip, it is followed by a first rinse and side brushing. In this embodiment, the side brushing mechanism 9 includes two vertical brush rollers 91 spaced apart along the width of the frame 1. The vertical brush rollers 91 are driven to rotate by a motor to brush both sides of the turnover box 13. Then, a second spray rinse is performed. After rinsing, a second 360° flip is performed to remove accumulated water from the inside and outside, reducing residue problems. In this embodiment, the first air-cutting mechanism 15 is located above the second 360° flipping mechanism 7, allowing the first air-cutting mechanism 15 to perform air-cutting drying during and after the turnover box 13 is flipped.

[0036] After air-cutting and drying, the turnover box 13 is conveyed via the second conveyor frame 14. In this embodiment, the second air-cutting mechanism 16 is located on both sides and above the second conveyor frame 14, and continues air-cutting and drying during the conveying process without affecting the conveying of the turnover box 13, thus improving production efficiency.

[0037] like Figure 1 As shown, an arc-shaped guide hood 17 is provided on the frame 1 behind the second conveyor frame 14. The upper part of the arc-shaped guide hood 17 is connected to the second conveyor frame 14, and the lower part of the arc-shaped guide hood 17 bends and extends to the bottom of the second conveyor frame 14. A third conveyor frame 18 is provided in the frame 1 below the second conveyor frame 14 and connected to the lower part of the arc-shaped guide hood 17. The turnover box 13 is fed into the arc-shaped guide hood 17 through the second conveyor frame 14, slides down the arc-shaped guide hood 17, flips 180° and falls into the third conveyor frame 18, and continues to be conveyed with its front facing upward.

[0038] A third air-cutting mechanism 19, corresponding to the third conveyor frame 18, is installed on the frame 1 for continued air-cutting drying, resulting in a compact structure. The third air-cutting mechanism 19 can use hot air for air-cutting drying, improving the drying effect of the turnover box 13.

[0039] like Figure 2As shown, a fourth conveyor 20 is provided on one side of the frame 1, which is perpendicular to the third conveyor 18, to realize the output of the turnover box 13 after cleaning and drying. The design of the third conveyor 18 and the fourth conveyor 20 reduces the overall length of the equipment and improves the space utilization.

[0040] In summary, the turnover box cleaning machine disclosed in this invention can perform multiple turnover boxes for washing and drying, improving cleaning efficiency and effect. Moreover, its compact structure helps to reduce the requirements for factory length and lower costs.

[0041] The above are merely embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
