For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be internal communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0022] like Figures 1 to 10 As shown, the chain transmission device 100 of the present invention includes a connecting track 2 , a conveying chain 3 transmitted in the connecting track 2 , and a track cleaning device 1 .

[0023] There are multiple connecting rails 2, which are connected to each other to form multiple tracks. In this embodiment, the cross section of the connecting rails 2 is U-shaped with an opening facing upward.

[0024] In this embodiment, the conveying chain 3 is composed of multiple interconnected chain sections, and each section of the chain includes a connecting plate 31 extending along the moving direction, a guide bearing, a moving roller and other structures to achieve high-speed movement of the conveying chain 3 in the connecting track 2.

[0025] The track cleaning device 1 is used to clean the connecting track 2 of the chain transmission device 100 to prevent oil, dust, etc. from accumulating in the connecting track 2.

[0026] like Figures 2 to 7 As shown, the track cleaning device 1 includes a cleaning track 11 , a cleaning member 12 , an oil receiving pan 13 , and a fixing member 14 .

[0027] The cleaning member 12 includes a limiting baffle 121 and an oil scraper ring block 122 fixed on the conveying chain 3 .

[0028] In this embodiment, the stopper plate 121 is fixed to the connecting plate 31. It blocks the oil scraper ring 122, preventing it from moving relative to the conveyor chain 3 due to friction. The stopper plate 121 can be secured to the connecting plate 31 by welding, interference fit, or integral molding. The location on the conveyor chain 3 corresponding to the stopper plate 121 can be marked to facilitate user identification of the location of the stopper plate 121. For example, the location corresponding to the stopper plate 121 can be painted a different color.

[0029] The limit baffle 121 is preferably made of a material with good rigidity, such as metal, and its size is smaller than the connecting track 2 to avoid scratches with the connecting track 2. When the connecting track 2 does not need to be cleaned, the limit baffle 121 can be retained without interfering with the connecting track 2 and affecting the normal operation of the conveying chain 3.

[0030] The oil scraper ring block 122 is used to be sleeved on the conveying chain 3 and is detachably arranged with the conveying chain 3. The limit baffle 121 abuts against the oil scraper ring block 122 along the forward direction of the conveying chain 3. In this embodiment, when the conveying chain 3 moves forward, the limit baffle 121 is located behind the oil scraper ring block 122.

[0031] The oil scraper ring block 122 is made of a flexible material, and in this embodiment, can be made of a rubber material or a plastic material. Of course, in other embodiments, non-flexible materials can also be used, as long as the strength is low and the connecting rail 2 is not scratched.

[0032] The track cleaning device 1 has a cleaning state and a standby state. When the track cleaning device 1 is in the cleaning state, the oil scraper ring block 122 is sleeved on the conveying chain 3 and abuts against the bottom and side wall of the connecting track 2. When the track cleaning device 1 is in the normal state, the oil scraper ring block 122 is detached from the conveying chain 3.

[0033] A through hole 1221 is provided in the middle of the oil scraper ring block 122 for the connecting plate 31 to pass through, and a notch 1222 is provided on the edge of the oil scraper ring block 122 to communicate with the through hole 1221 so that the oil scraper ring block 122 can be clamped on the connecting plate 31.

[0034] In this embodiment, the oil scraper ring 122 is a consumable part. After one or more cleaning operations and wear, the oil scraper ring 122 needs to be replaced. The provision of the clearance notch 1222 facilitates replacement of the oil scraper ring 122. This arrangement can be applied to the existing connecting rail 2, eliminating the need for a separate chain.

[0035] When the track cleaning device 1 is in the cleaning state, the conveying chain 3 moves, and the oil scraper ring block 122 scrapes the oil on the bottom and side walls of the connecting track 2, and pushes the oil to move in the connecting track 2 until it is discharged to the cleaning track 11 for oil discharge, thereby ensuring the cleanliness and hygiene of the inside of the connecting track 2.

[0036] In this embodiment, the cleaning track 11 can be single or multi-section, with both sides of the cleaning track 11 connected to the connecting track 2. The cleaning track 11 can serve as part of the connecting track 2, allowing the conveyor chain 3 to move normally. When the cleaning track 11 is configured with multiple sections, it can be installed at multiple locations on the chain transmission device 100 to avoid excessive oil spillage after scraping. The multi-section cleaning track 11 allows the oil scraper ring block 122 to quickly remove the oil from a section of the track after scraping.

[0037] Correspondingly, the number of the limiting baffle 121 and the oil scraper ring block 122 can also be set to multiple, so as to improve the cleaning effect, reduce the number of repeated operations, and improve the cleaning efficiency.

[0038] like Figures 8 to 10 As shown, in one embodiment, the oil scraper ring block 122 includes a first oil scraper portion 1223 that is abutted against the limiting baffle 121, a second oil scraper portion 1224 located on the side of the first oil scraper portion 1223 away from the limiting baffle 121, and a connecting portion 1225 connecting the first oil scraper portion 1223 and the second oil scraper portion 1224. The first oil scraper portion 1223 is abutted against the side wall of the connecting rail 2 along the width direction, and the width of the second oil scraper portion 1224 is smaller than the width of the first oil scraper portion 1223.

[0039] In this embodiment, the second oil scraping portion 1224 is located at the front side during cleaning. The width of the second oil scraping portion 1224 is smaller than and close to the inner width of the connecting rail 2. The second oil scraping portion 1224 can preliminarily scrape off oil stains.

[0040] The width of the first oil scraping portion 1223 is equal to the width of the inner side of the connecting track 2, and the first oil scraping portion 1223 can scrape the oil stains on the connecting track 2 twice. Scraping twice can achieve a better oil scraping and cleaning effect.

[0041] In this embodiment, first oil scraping protrusions 1226 are provided on both ends of the first oil scraping portion 1223 on one side facing the second oil scraping portion 1224, extending outward along the width direction. The spacing between the first oil scraping protrusions 1226 is slightly larger than the width of the inner side of the connecting rail 2. The first oil scraping protrusions 1226 are formed into a bell-mouth shape, achieving a better cleaning effect on the inner wall of the connecting rail 2.

[0042] The bottom of the first oil scraping portion 1223 is protruded downward to form a second oil scraping protrusion 1227. The second oil scraping protrusion 1227 is used to scrape off the oil on the bottom of the connecting track 2.

[0043] In this embodiment, the first oil scraping protrusion 1226 and the second oil scraping protrusion 1227 become thinner from the first oil scraping portion 1223 toward the outside, and the fit between the first oil scraping protrusion 1226 and the connecting rail 2 can be strengthened, so that the cleaning intensity is increased to further achieve a better scraping effect.

[0044] like Figure 5 As shown, the cleaning track 11 includes a bottom plate 111 , connectors 112 disposed at both ends of the bottom plate 111 , and side plates 113 disposed at both sides of the bottom plate 111 .

[0045] An oil drain port 1111 is provided at the bottom of the cleaning track 11. In this embodiment, the oil drain port 1111 is arranged on the bottom plate 111, and there are multiple oil drain ports 1111. The multiple oil drain ports 1111 are arranged at intervals along the moving direction of the conveying chain 3. Oil stains can be discharged from the oil drain port 1111, thereby achieving continuous cleaning, avoiding repeated shutdowns for cleaning, and shortening cleaning time.

[0046] The connecting member 112 is used to connect with the connecting rail 2. In this embodiment, the connecting member 112 is detachably connected to the connecting rail 2, and the cleaning rail 11 can replace a section of the connecting rail 2, so that the rail cleaning device 1 of this embodiment can be applied to existing common rail cleaning devices 1.

[0047] In this embodiment, the side plates 113 and the bottom plate 111 are detachably arranged. When the oil scraper ring block 122 needs to be removed or installed, the side plates 113 can be removed, and the side plates 113 can be installed before the track cleaning device 1 is cleaned.

[0048] The connection plate 31 is exposed by providing a detachable side plate 113 , which facilitates the installation of the oil scraper ring block 122 .

[0049] The fixing member 14 is fixedly connected to the bottom plate 111. The fixing member 14 extends downward from the bottom plate 111 and is provided with a connection hole. The side panels 113 are detachably connected to the fixing member 14. In this embodiment, the side panels 113 and the fixing member 14 can be connected by bolts and nuts, or the connection holes can be set as threaded holes and directly connected by bolts or screws.

[0050] The side plate 113 includes a blocking plate 1131 and a connecting baffle 1132 . The blocking plate 1131 is used to block both sides of the cleaning track 11 to prevent oil leakage. The connecting baffle 1132 is used to be fixedly connected to the fixing member 14 to fix the side plate 113 .

[0051] In this embodiment, there are at least two fixing members 14 , which are disposed at both ends of the bottom plate 111 .

[0052] The oil receiving pan 13 is located below the cleaning track 11. The oil in the cleaning track 11 falls into the oil receiving pan 13 through the oil drain port 1111.

[0053] The oil pan 13 is provided with retaining members at both ends, and the fixing member 14 is provided with retaining grooves. The retaining members engage with the retaining grooves through which the oil pan 13 is secured. When the oil pan 13 is contaminated with oil, the pan 13 can be removed for cleaning. The engagement of the retaining members and retaining grooves makes the oil pan 13 easy to assemble and disassemble.

[0054] When the chain transmission device 100 needs to be cleaned, first find the position of the limit baffle 121, drive the conveying chain 3 to drive, so that the limit baffle 121 moves to the cleaning track 11, remove the side plate 113, install the oil scraper ring block 122, and then install the side plate 113; start the conveying chain 3, scrape the oil to the cleaning track 11 and discharge it to the oil receiving pan 13 until the connecting track 2 is clean enough; move the limit baffle 121 to the cleaning track 11, remove the side plate 113, remove the oil scraper ring block 122, and then install the side plate 113, remove the oil receiving pan 13, and pour out the oil.

[0055] The track cleaning device 1 and the chain conveying equipment of the present invention are provided with a detachable oil scraper ring block 122, so that the cleaning of the connecting track 2 can be achieved without making a special cleaning chain. The structure is simple and the cleaning efficiency is high. The bottom of the cleaning track 11 is provided with evenly distributed oil drain ports 1111, which can be used to discharge excess lubricating oil during normal operation to reduce the accumulation of oil stains. During cleaning, there is no need to repeatedly stop the machine to clean the oil stains accumulated in front of the oil scraper ring block 122, which is more convenient and shortens the time required for the entire cleaning cycle.

[0056] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
