Description

Technical Field

[0001] This utility model relates to the field of logistics conveying equipment technology, specifically to a rotary pallet cleaning device. Background Technology

[0002] In the core-making department of the foundry, sand cores need to be coated with a layer of paint on their surface and then placed on a tray for drying in a surface drying oven. When the coated sand cores are placed on the tray, the paint will adhere to the tray. After drying in the surface drying oven, the paint will be firmly bonded to the tray. After a long period of production, the paint layer on the tray will become thicker and thicker, which will directly affect the relative position of the sand core and the tray.

[0003] In traditional manual operation, as long as the sand core can be placed stably, the coating layer has little impact. However, more and more factories are now using robots or automated equipment for dip coating, core placement, and core removal after drying. This process requires high positional accuracy of the sand core. The coating adhering to the tray can raise the height of the sand core, and uneven coating layer distribution may also cause changes in the position and orientation of the sand core. All of these will affect the work of robots or automated equipment for core placement and removal. Therefore, it is necessary to clean the coating on the surface of the tray.

[0004] Manual cleaning wastes human resources, and most factories use a double-layer conveyor system to save floor space. The upper conveyor belt carries full-load pallets with sand cores, while empty pallets return from the lower conveyor, which makes it very inconvenient for personnel to clean the pallets.

[0005] The shortcomings and technical problems of existing technologies include:

[0006] Because the paint adheres firmly to the tray, it cannot be cleaned directly by blowing with compressed air or brushing with a brush.

[0007] Existing automated pallet cleaning methods mainly include scraper type and roller type. Due to the difficulty in ensuring the flatness of the conveyor line and pallet, the scraper must leave a certain safety gap with the pallet surface to avoid collision. As a result, the coating on the pallet surface cannot be completely scraped off, and only coatings exceeding a certain thickness can be scraped off. The contact area between the roller wire brush of the roller pallet cleaning device and the pallet surface is small, and the cleaning time for various parts of the surface is short when the pallet passes by, making it difficult to clean thoroughly. Utility Model Content

[0008] To address these issues, this invention provides a rotary pallet cleaning device to solve the problems of scraper-type pallet cleaning devices being unable to clean pallets in a close-fitting manner, and roller-type cleaning devices having too small a contact area with the pallet and too short a cleaning time, thus failing to achieve thorough cleaning.

[0015] Preferably, at least two adjusting screws are provided, and the two adjusting screws are arranged symmetrically between each other.

[0016] Preferably, the crossbeam is provided with fixing holes, and the number of fixing holes is the same as the number of rotating shafts.

[0017] Preferably, the wire brush is detachably connected to the rotating shaft, and the number of wire brushes is the same as the number of rotating shafts.

[0018] Preferably, at least three rotating shafts and wire brushes are provided, including a first rotating shaft, a second rotating shaft, and a third rotating shaft, a first wire brush, a second wire brush, and a third wire brush. The first rotating shaft is connected to the first wire brush, the second rotating shaft is connected to the second wire brush, and the third rotating shaft is connected to the third wire brush. The first rotating shaft, the second rotating shaft, and the third rotating shaft are arranged sequentially, and the first rotating shaft, the second rotating shaft, and the third rotating shaft are arranged along the axial direction of the crossbeam.

[0019] Preferably, the wire brush is a disc wire brush.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] A specific embodiment of this utility model provides a rotary tray cleaning device, combined with an attached... Figure 1 As shown, the device in this embodiment is installed above the roller conveyor, which is used to transport pallets. In this embodiment, the pallet is shaped like a mountain, and the surface of the pallet is cleaned by the wire brush 6 of the device in this embodiment.

[0035] Specifically, it includes a crossbeam 1, with lifting and adjusting mechanisms at both ends of the crossbeam 1 and a driving mechanism on one side of the crossbeam 1;

[0036] The drive mechanism includes a drive motor 2, a coupling 3, and a transmission shaft 4. The drive motor 2 is connected to the coupling 3, and the transmission shaft 4 is rotatably connected to the coupling 3.

[0037] The cleaning mechanism includes a rotating shaft 5 and a wire brush 6. The wire brush 6 is connected to the output end of the rotating shaft 5, and the rotating shaft 5 is fixed in the crossbeam 1.

[0038] The transmission mechanism is equipped with a transmission belt 7, which connects the transmission shaft 4 and the rotating shaft 5.

[0039] Specifically, the lifting and adjusting mechanism is provided with a connecting seat 8 and an adjusting screw 9, such as Figure 1 , 2 As shown, the connecting seat 8 is threadedly connected to the adjusting screw 9, and the adjusting screw 9 is perpendicular to the top surface of the connecting seat 8. There are at least two adjusting screws 9. In this embodiment, two adjusting screws 9 are symmetrically arranged at both ends of the connecting seat 8. The connecting seat 8 is located above the crossbeam 1 and fits against the crossbeam 1. The adjusting screw 9 passes through the connecting seat 8 and is fixed to the crossbeam 1. By adjusting the relative position of the adjusting screw 9 with respect to the connecting seat 8, the lifting and lowering adjustment of the crossbeam 1 can be achieved.

[0040] Specifically, the crossbeam 1 is provided with fixing holes 10. In this embodiment, there are three fixing holes 10, which are arranged in a straight line along the axial direction of the crossbeam 1. The fixing holes 10 are symmetrically arranged and are also arranged in the direction of the center line of the tray. The fixing holes 10 are used to place and fix the rotating shaft 5.

[0041] Specifically, the rotating shaft 5 includes a first rotating shaft, a second rotating shaft, and a third rotating shaft. The output end of the rotating shaft 5 is provided with a wire brush. In this embodiment, the wire brush is a disc wire brush, and the maximum diameter of the disc wire brush is equal to or greater than its corresponding tray. The wire brush includes a first wire brush, a second wire brush, and a third wire brush. The output end of the first rotating shaft is provided with a first wire brush, the output end of the second rotating shaft is provided with a second wire brush, and the output end of the third rotating shaft is provided with a third wire brush. The first rotating shaft is located close to the transmission shaft 4. Since the tray is set in a mountain shape in this embodiment, the length of the output end of the second rotating shaft is shorter than the length of the output ends of the first and third rotating shafts.

[0042] Specifically, the drive motor 2 is located on the side of the crossbeam, and the output end of the drive motor 2 is set perpendicular to the crossbeam 1. The output end of the drive motor 2 is connected to the coupling 3, the coupling 3 is connected to the transmission shaft 3, the transmission shaft 3 is connected to the first rotating shaft through the transmission belt 7, the first rotating shaft is connected to the second rotating shaft through the transmission belt 7, and the second rotating shaft is connected to the third rotating shaft through the transmission belt 7. The drive motor 2 provides rotational power, drives the transmission shaft 4 to rotate, and drives the first rotating shaft, the second rotating shaft and the third rotating shaft to rotate through the transmission belt 7.

[0043] Specifically, in this embodiment, the transmission mechanism is also provided with a tensioning wheel 11, such as... Figure 3 As shown, tensioning wheels 11 are located on the side of the crossbeam 1. There are three tensioning wheels 11, matching the number of rotating shafts 5, wire brushes 6, and fixing holes 10. Three tensioning wheels are positioned between the drive shaft 4 and the first rotating shaft to adjust the tension of the drive belt 7; three are positioned between the first and second rotating shafts to adjust the tension of the drive belt 7; and three are positioned between the second and third rotating shafts to adjust the tension of the drive belt 7. Figure 4 As shown, the tensioning wheel 11 is equipped with a connecting plate, which is connected to the crossbeam 1. A sliding track is provided at the connecting plate, and a movable plate is provided between the sliding tracks to drive the tensioning wheel body to move and adjust the tension of the transmission belt 7. The rotating shaft of the tensioning wheel body is vertically connected and fixed above the movable plate. An adjusting rod is provided on the outer side of the rotating shaft along the axial direction of the sliding track. By pulling the rotating shaft with the adjusting rod, the movable plate is moved along the sliding track. Moving outward can increase the tension of the transmission belt 7, and moving inward can decrease the tension of the transmission belt 7. After moving to a suitable position, the movable plate can be fixed with bolts.

[0044] The working principle of this embodiment is as follows: Figure 2 As shown, before the tray arrives at the device of this embodiment, the brush surface (lowest plane) of the disc wire brush should be slightly lower than the corresponding surface on the tray; when the brush surface of the disc wire brush is worn to a certain extent after a period of use, a certain degree of height compensation can be achieved by adjusting the screw of the adjusting component 11 to avoid replacing the wire disc brush too early.

[0045] Example 2:

[0046] like Figure 5 As shown, depending on the specific pallet structure, the disc wire brush in this embodiment can be one or more: when the pallet width is narrow (the pallet runs along its length), and one disc brush can cover the width of the pallet, only one disc brush can be used; when the pallet is wide, multiple disc brushes with parallel axes and all perpendicular to the pallet surface can be used in combination; when there are multiple surfaces of different heights (step-like) on the pallet surface, multiple disc brushes of different heights are needed to clean each surface separately; when there is enough space above the pallet (such as when the conveyor line is a single-layer roller conveyor), the drive motor can be arranged above the pallet to drive the disc wire brush directly or indirectly.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
