[0024] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0025] In related technologies, tobacco storage cabinets are specialized equipment used in tobacco processing to store tobacco leaves, shredded tobacco, and other materials. This ensures the materials are evenly mixed and fully absorb flavoring during storage, while also balancing process parameters such as moisture content and temperature. The conveyor chains in tobacco storage cabinets are prone to jamming, knots, wear, and abnormal noise, requiring lubrication. Currently, chain lubrication relies primarily on manual periodic application or spraying of lubricating oil, which has the following drawbacks: manual operation makes it difficult to precisely control the amount and coverage of lubricating oil, easily leading to insufficient or excessive lubrication in certain areas, exacerbating wear and even causing jamming and abnormal noise; manual lubrication requires frequent equipment start-ups and shutdowns, affecting production line continuity and increasing the safety risks for operators contacting mechanical transmission parts; due to the large size and numerous lubrication points in tobacco storage cabinets, manual lubrication is labor-intensive and time-consuming. Currently, it is difficult to precisely control the coverage of lubricating oil on the conveyor chains of tobacco storage cabinets during lubrication, resulting in localized over- or under-lubrication, affecting the lubrication effect.
[0026] refer to Figure 1 As shown, an embodiment of this application provides a chain lubrication device 100, which includes a frame 110, a support assembly 120, and a lubrication assembly 130.
[0027] Specifically, in combination Figure 2 and Figure 3 As shown, the frame 110 is equipped with a transmission chain 111, and the support assembly 120 is connected to the side of the frame 110 near the transmission chain 111. The lubrication assembly 130 includes a lubricating element 132 and a lubrication pump 131. The output end of the lubrication pump 131 is connected to the oil inlet end of the lubricating element 132. The lubricating element 132 is connected to the support assembly 120, and the oil outlet end of the lubricating element 132 is provided with a first limiting edge 1321 and a second limiting edge 1322. The oil outlet end of the lubricating element 132 is capable of abutting against the transmission chain 111, and the transmission chain 111 is located at the first limiting edge 1321. Between 21 and the second limiting edge 1322, correspondingly, the transmission chain 111 is mounted on the frame 110. The transmission chain 111 is used for material transmission. The lubrication pump 131 is connected to the lubricating element 132 and delivers lubricating oil to the lubricating element 132. During the transmission process of the transmission chain 111, the oil outlet end of the lubricating element 132 can apply lubricating oil to the transmission chain 111, so that the lubricating element 132 lubricates the transmission chain 111. The first limiting edge 1321 and the second limiting edge 1322 are used to limit the transmission chain 111 to avoid the lubrication position of the lubricating element 132 from shifting or misaligning, thereby improving the lubrication effect of the chain lubrication device 100.
[0028] The brush head of the lubricating component 132 has a notched structure and is a sponge brush adapted to the shape of the transmission chain 111. The brush head has high bundle tension and oil wetting rate, and the first limiting edge 1321 and the second limiting edge 1322 can fully wrap the transmission chain 111, so that the brush head can fully contact the transmission chain 111 to ensure a large coverage of the oiling surface.
[0029] For example, the lubrication pump 131 is used to pump lubricating oil. The bottom of the lubrication pump 131 is connected to the oil inlet of the lubricating component 132 through an oil delivery pipe. The lubrication pump 131 has an oil storage space inside and can use a screw structure to realize the pumping of lubricating oil. The lubrication pump 131 combines an oil pump and an oil storage tank to ensure the simplification and integration of the delivery and storage methods of the lubrication pump 131.
[0030] refer to Figure 1 and Figure 2 As shown, the chain lubrication device 100 has a first direction X, a second direction Y, and a third direction Z, wherein the first direction X, the second direction Y, and the third direction Z are arranged perpendicularly to each other. For example, the first direction X refers to the length direction of the chain lubrication device 100, the second direction Y refers to the width direction of the chain lubrication device 100, and the third direction Z refers to the height direction of the chain lubrication device 100. It is understood that the above definitions are only for ease of understanding the relative positional relationships of the various parts in the chain lubrication device 100 and should not be construed as limitations on this application.
[0031] In one embodiment, alternatively, referencing Figure 3 As shown, the line connecting the first limiting edge 1321 and the second limiting edge 1322 is perpendicular to the transmission direction of the transmission chain 111. The first limiting edge 1321 and the second limiting edge 1322 can regulate and limit the application of lubricating oil to the lubricating element 132. The arrangement of the first limiting edge 1321 and the second limiting edge 1322 will not affect or obstruct the transmission of the transmission chain 111. For example, the first limiting edge 1321 and the second limiting edge 1322 are arranged along the first direction X, and the transmission direction of the transmission chain 111 is the second direction Y.
[0032] Optionally, such as Figure 1 As shown, there are two transmission chains 111, which are respectively located at opposite ends of the frame 110. That is, the two transmission chains 111 are respectively located at opposite ends of the frame 110 along the first direction X. Each transmission chain 111 transmits materials along the second direction Y. Each transmission chain 111 corresponds to a lubrication component 130.
[0033] In one embodiment, optionally, the frame 110 is provided with a connecting beam 112, and each of the transmission chains 111 is provided with a plurality of chain links 1111 at intervals. The opposite ends of the connecting beam 112 are respectively connected to two oppositely provided chain links 1111. The connecting beam 112 is used to support and connect the chain links 1111 so that the transmission chain 111 can be driven through the chain links 1111.
[0034] Furthermore, such as Figure 3 As shown, the first plate 1221 and the second plate 1222 are arranged perpendicularly. The first plate 1221 is used to connect and install the lubricating component 132, and the second plate 1222 is attached to the bracket body 121 and fixed by bolts.
[0035] In summary, the transmission chain 111 of the chain lubrication device 100 is mounted on the frame 110. The transmission chain 111 is used for material transmission. The lubrication pump 131 is connected to the lubricating component 132 and delivers lubricating oil to the lubricating component 132. During the transmission process of the transmission chain 111, the oil outlet end of the lubricating component 132 can apply lubricating oil to the transmission chain 111, so that the lubricating component 132 lubricates the transmission chain 111. The first limiting edge 1321 and the second limiting edge 1322 are used to limit the transmission chain 111 to prevent the lubrication position of the lubricating component 132 from shifting or misaligning, thereby improving the lubrication effect of the chain lubrication device 100.
[0036] refer to Figure 1 As shown, an embodiment of this application provides another chain lubrication device 100, which includes a frame 110, a support assembly 120, and a lubrication assembly 130.
[0037] Specifically, in combination Figure 2 and Figure 3 As shown, the frame 110 is provided with a transmission chain 111, and the support assembly 120 is connected to the side of the frame 110 near the transmission chain 111. The transmission chain 111 is mounted on the frame 110 and is used for material transmission.
[0038] In this embodiment, the lubrication assembly 130 includes a lubricating element 132 and a lubrication pump 131. The output end of the lubrication pump 131 is connected to the oil inlet end of the lubricating element 132. The lubricating element 132 is connected to the support assembly 120, and the oil outlet end of the lubricating element 132 is provided with a first limiting edge 1321 and a second limiting edge 1322 opposite to each other. The oil outlet end of the lubricating element 132 is capable of abutting against the transmission chain 111, and the transmission chain 111 is located between the first limiting edge 1321 and the second limiting edge. Between 1322, correspondingly, the lubrication pump 131 connects to the lubrication component 132 and delivers lubricating oil to the lubrication component 132. During the transmission process of the transmission chain 111, the oil outlet end of the lubrication component 132 can apply lubricating oil to the transmission chain 111, so that the lubrication component 132 lubricates the transmission chain 111. The first limiting edge 1321 and the second limiting edge 1322 are used to limit the transmission chain 111 to avoid the lubrication position of the lubrication component 132 from shifting or misaligning, thereby improving the lubrication effect of the chain lubrication device 100.
[0039] In one embodiment, alternatively, referencing Figure 3 As shown, the line connecting the first limiting edge 1321 and the second limiting edge 1322 is perpendicular to the transmission direction of the transmission chain 111. The first limiting edge 1321 and the second limiting edge 1322 can regulate and limit the application of lubricating oil to the lubricating component 132. The setting of the first limiting edge 1321 and the second limiting edge 1322 will not affect or hinder the transmission of the transmission chain 111.
[0040] Optionally, such as Figure 1 As shown, there are two transmission chains 111, which are respectively located at opposite ends of the frame 110. That is, the two transmission chains 111 are respectively located at opposite ends of the frame 110 along the first direction X, and each transmission chain 111 transmits materials along the second direction Y.
[0041] In one embodiment, optionally, the frame 110 is provided with a connecting beam 112, and each transmission chain 111 is provided with a plurality of chain links 1111 at intervals. The opposite ends of the connecting beam 112 are respectively connected to two chain links 1111 arranged opposite to each other. The connecting beam 112 is used to support and connect the chain links 1111 so that the transmission chain 111 can be driven through the chain links 1111.
[0042] For example, the chain link 1111 has a circular structure, and the chain is arranged around multiple chain links 1111 to form an annular chain, which can be driven to move by a speed reducer.
[0043] In one embodiment, optionally, combining Figure 2 and Figure 3As shown, the bracket assembly 120 includes a bracket body 121 and a first connector 122. The first connector 122 is provided with a first plate 1221 and a second plate 1222. The first plate 1221 has a through hole 1221a. One side of the first plate 1221 is detachably connected to the lubricant 132. The lubricant 132 is connected to the lubrication pump 131 through an oil supply pipe. The oil supply pipe passes through the through hole 1221a. The second plate 1222 is connected to the bracket body 121. The lubricant 132 is installed on the bracket body 121 through the first connector 122, and the lubricant 132 can be detached from the first plate 1221 of the first connector 122 by bolts. The oil supply pipe of the lubricant 132 passes through the through hole 1221a and is connected to the lubrication pump 131.
[0044] Furthermore, such as Figure 3 and Figure 4 As shown, the first plate 1221 and the second plate 1222 are arranged perpendicularly. The first plate 1221 is used to connect and install the lubricating component 132, and the second plate 1222 is attached to the bracket body 121 and fixed by bolts.
[0045] Optionally, such as Figure 4 As shown, the two ends of the support body 121 are respectively connected to the frame 110. A gap 140 is formed between the support body 121 and the frame 110, which allows the transmission chain 111 to pass through. That is, the transmission chain 111 is located between the support body 121 and the frame 110. The support body 121 will not affect or hinder the normal transmission of the transmission chain 111, while ensuring that the overall structure is relatively compact and has a high space utilization rate.
[0046] In one embodiment, alternatively, referencing Figure 2 As shown, the chain lubrication device 100 further includes a detection element 150, and the support assembly 120 further includes a second connector 123. The detection element 150 is connected to the support body 121 through the second connector 123. The detection element 150 is positioned facing the frame 110. The detection element 150 can detect and identify the relative position of the lubricating element 132 and the transmission chain 111. The detection element 150 can be a vision camera or an industrial camera. Of course, the detection element 150 can also be a detection sensor to determine the lubrication position of the lubricating element 132. The transmission chain 111 periodically triggers the detection signal of the detection element 150. For example, when the transmission chain 111 is driven to the lubrication position of the lubricating element 132, the detection element 150 sends a signal to the control element 160 to start the lubrication pump 131 and control the opening or closing of the lubricating element 132 to achieve precise lubrication.
[0047] In one embodiment, alternatively, such as Figure 1As shown, the chain lubrication device 100 also includes a control component 160, which is electrically connected to the lubrication assembly 130. It can automatically complete the entire lubrication process, effectively ensuring the effectiveness and timeliness of lubrication of the transmission chain 111 of the tobacco storage cabinet. The structure is relatively compact and easy to maintain. The control can be a PLC controller, which executes low-level control commands to ensure real-time performance. The control component 160 is used to control the opening or closing of the lubrication pump 131 and the lubrication component 132, realizing dynamic lubrication cycle optimization and improving lubrication timeliness and accuracy.
[0048] An embodiment of this utility model also provides a tobacco storage cabinet, including the chain lubrication device 100 described in any of the above embodiments. The tobacco storage cabinet uses the chain lubrication device 100 to facilitate the lubrication of the transmission chain 111. The tobacco storage cabinet including the chain lubrication device 100 has all the beneficial effects of the chain lubrication device 100, which will not be described in detail here.
[0049] In all examples shown and described herein, any specific values should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.
[0050] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
