In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0032] As shown in Figures 1 to 10 The chain transmission device 100 of the present application comprises a connecting track 2, a conveying chain 3 conveyed in the connecting track 2, and a track cleaning device 1.

[0033] The number of the connecting track 2 is multiple, and they are connected with each other to form multiple tracks. In this embodiment, the cross section of the connecting track 2 is in the shape of U with the opening upward.

[0034] In this embodiment, the conveying chain 3 is composed of multiple chains connected with each other, and each chain comprises a connecting plate 31 extending in the moving direction, a guide bearing, a moving roller and the like to realize the high-speed movement of the conveying chain 3 in the connecting track 2.

[0035] The track cleaning device 1 is used to clean the connecting track 2 of the chain transmission device 100 to avoid the accumulation of oil stains, dust and the like in the connecting track 2.

[0036] As shown in Figures 2 to 7As shown, the track cleaning device 1 comprises a cleaning track 11, a cleaning piece 12 and an oil receiving tray 13, a fixing piece 14.

[0037] The cleaning piece 12 comprises a limiting baffle 121 fixed on the conveying chain 3, an oil scraping ring block 122.

[0038] In the embodiment, the limiting baffle 121 is fixed on the connecting plate 31, and the limiting baffle 121 is used to block the oil scraping ring block 122 to avoid the oil scraping ring block 122 from moving relative to the conveying chain 3 under the friction force. The limiting baffle 121 can be fixed on the connecting plate 31 by welding, interference fit or one-piece forming, and the position corresponding to the limiting baffle 121 of the conveying chain 3 can be provided with distinguishing marks to facilitate the user to identify the position of the limiting baffle 121. For example, different colors are applied at the position corresponding to the limiting baffle 121.

[0039] The limiting baffle 121 is preferably made of a material with good rigidity, such as metal, and its size is smaller than that of the connecting track 2 to avoid scratching the connecting track 2. When the connecting track 2 does not need to be cleaned, the limiting baffle 121 can be retained without interfering with the connecting track 2 to affect the normal operation of the conveying chain 3.

[0040] The oil scraping ring block 122 is used to be sleeved on the conveying chain 3 and is detachably arranged with the conveying chain 3, and the limiting baffle 121 abuts against the oil scraping ring block 122 along the advancing direction of the conveying chain 3. In the embodiment, when the conveying chain 3 advances, the limiting baffle 121 is located behind the oil scraping ring block 122.

[0041] The oil scraping ring block 122 is made of a flexible material, which can be made of rubber material or plastic material in the embodiment. Of course, in other embodiments, a non-flexible material can also be used as long as it has low strength and will not scratch the connecting track 2.

[0042] 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 scraping ring block 122 is sleeved on the conveying chain 3 and abuts against the bottom and side wall of the connecting track 2, and when the track cleaning device 1 is in the normal state, the oil scraping ring block 122 is separated from the conveying chain 3.

[0043] The oil scraping ring block 122 is provided with a through hole 1221 for the connecting plate 31 to pass through in the middle, and the edge of the oil scraping ring block 122 is provided with a gap 1222 communicating with the through hole 1221 to allow the oil scraping ring block 122 to be clamped on the connecting plate 31.

[0044] In this embodiment, the oil scraper ring 122 is a consumable part. After wear occurs during one or more cleaning cycles, the oil scraper ring 122 needs to be replaced. The oil scraper ring 122 is designed with a clearance notch 1222 to facilitate replacement. Furthermore, this design can be applied to the existing connecting track 2 without the need for a separately designed chain.

[0045] When the track cleaning device 1 is in a clean state, the conveyor chain 3 moves, and the oil scraper ring 122 scrapes off the oil on the bottom and side wall of the connecting track 2 and pushes the oil to move inside the connecting track 2 until it is discharged to the clean track 11, thereby ensuring the cleanliness and hygiene of the inside of the connecting track 2.

[0046] In this embodiment, the cleaning track 11 can be one or more sections, and both sides of the cleaning track 11 are 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 set to multiple sections, it is installed at multiple locations on the chain drive device 100 to avoid the problem of excessive oil spillage after scraping. Setting multiple sections of the cleaning track 11 allows the oil to be scraped off a section of the track by the oil scraping ring block 122 and discharged as quickly as possible.

[0047] Correspondingly, the number of the limiting baffle 121 and the oil scraping ring block 122 can also be set to multiple, thereby improving the cleaning effect, reducing the number of repeated runs, and improving the cleaning efficiency.

[0048] like Figures 8 to 10 As shown, in one embodiment, the oil scraping ring block 122 includes a first oil scraping portion 1223 that abuts against the limiting baffle 121, a second oil scraping portion 1224 located on the side of the first oil scraping portion 1223 away from the limiting baffle 121, and a connecting portion 1225 connecting the first oil scraping portion 1223 and the second oil scraping portion 1224. The first oil scraping portion 1223 abuts against the side wall of the connecting track 2 along the width direction, and the width of the second oil scraping portion 1224 is smaller than the width of the first oil scraping portion 1223.

[0049] In this embodiment, the second oil scraping part 1224 is located on the front side during cleaning. The width of the second oil scraping part 1224 is smaller than and close to the inner width of the connecting track 2. The second oil scraping part 1224 can initially scrape away the oil stains.

[0050] The width of the first oil-scraping part 1223 is equal to the width of the inner side of the connecting track 2, and the first oil-scraping part 1223 can scrape off the oil stains on the connecting track 2 twice. The two scrapings can achieve a better oil-scraping and cleaning effect.

[0051] In the embodiment, the first oil scraping part 1223 is provided with first oil scraping protrusions 1226 protruding outward in the width direction at both ends of the side of the first oil scraping part 1223 facing the second oil scraping part 1224. The interval between the first oil scraping protrusions 1226 on both sides is slightly greater than the width of the inner side of the connecting track 2, and the first oil scraping protrusions 1226 form a flared shape, achieving a better cleaning effect on the inner wall of the connecting track 2.

[0052] The bottom of the first oil scraping part 1223 is provided with second oil scraping protrusions 1227 protruding downward. The second oil scraping protrusions 1227 are used to scrape oil from the bottom of the connecting track 2.

[0053] In the embodiment, the first oil scraping protrusions 1226 and the second oil scraping protrusions 1227 become thinner and thinner from the first oil scraping part 1223 to the outside, and the fit between the first oil scraping part 1223 and the connecting track 2 is enhanced, so that the cleaning strength is increased, and a better scraping effect is achieved.

[0054] As shown in Figure 5 The cleaning track 11 includes a bottom plate 111, connecting pieces 112 provided at both ends of the bottom plate 111, and side plates 113 provided on both sides of the bottom plate 111.

In the embodiment, the oil discharge ports 1111 are provided on the bottom plate 111, and the number of oil discharge ports 1111 is multiple. The multiple oil discharge ports 1111 are arranged at intervals in the moving direction of the conveying chain 3, and oil stains can be discharged from the oil discharge ports 1111. Thus, continuous cleaning is achieved, repeated shutdown for cleaning is avoided, and cleaning time is shortened.

[0056] The connecting pieces 112 are used to connect with the connecting track 2. In the embodiment, the connecting pieces 112 are detachably connected with the connecting track 2, and the cleaning track 11 can replace a section of the connecting track 2. Thus, the track cleaning device 1 of the embodiment can be applied to an existing ordinary track cleaning device 1.

[0057] In the embodiment, the side plates 113 are detachably provided with the bottom plate 111. When the oil scraping ring block 122 needs to be removed or installed, the side plates 113 can be removed, and the side plates 113 are installed before the track cleaning device 1 is cleaned.

[0058] By providing detachable side plates 113, the connecting plate 31 is exposed, and the oil scraping ring block 122 is facilitated to be installed.

[0059] The fixing piece 14 is fixedly connected with the bottom plate 111, the fixing piece 14 extends downward from the bottom plate 111, the fixing piece 14 is provided with a connecting hole, and the side plate 113 is detachably connected with the fixing piece 14.

[0060] The side plate 113 comprises a blocking plate 1131 and a connecting blocking plate 1132, the blocking plate 1131 is used to block on both sides of the cleaning track 11 to avoid oil leakage, and the connecting blocking plate 1132 is used to be fixedly connected with the fixing piece 14 to realize the fixation of the side plate 113.

[0061] In the embodiment, the number of the fixing pieces 14 is at least two, and the fixing pieces 14 are arranged at both ends of the bottom plate 111.

[0062] The oil receiving disc 13 is located below the cleaning track 11. The oil in the cleaning track 11 falls into the oil receiving disc 13 through the oil discharge port 1111.
