Description

Technical Field

[0001] The utility model relates to the technical field of storage cabinets, in particular to a lubricating device for a bottom belt chain of a storage cabinet. Background Art

[0002] Tobacco leaf storage cabinets, also known as storage cabinets, are widely used in tobacco industry silk-making workshops. They primarily serve to buffer upstream and downstream equipment and balance various process parameters. Due to their large size and heavy loads, adequate lubrication of the storage cabinet's bottom chain is crucial to minimizing problems such as chain jams, kinks, wear on the chain plates and sprockets, abnormal noise, and breakage of the bottom drive shaft and chain.

[0003] Traditional lubrication methods often use press-can aerosol lubricants for manual spray lubrication, but there are prominent problems such as many lubrication points, high labor intensity, long time consumption, uneven lubrication, poor lubrication effect, and high lubricant loss.

[0004] There are some mechanical lubrication devices available in the prior art, but these are often unable to adjust to the actual operating conditions of the bottom chain. This can lead to insufficient lubrication due to insufficient oil dripping, or excessive oil dripping resulting in oil waste. Furthermore, impurities such as smoke and dust accumulated during operation of the cabinet bottom chain can mix into the lubricated area, compromising lubrication effectiveness. Utility Model Content

[0005] In view of this, the purpose of the present invention is to provide a cabinet bottom belt chain lubrication device to solve the problems of poor manual lubrication effect in the prior art, insufficient oil dripping resulting in insufficient lubrication of the existing mechanical lubrication device, or excessive oil dripping resulting in oil waste.

[0006] The utility model solves the above technical problems through the following technical means: a storage cabinet bottom belt chain lubricating device, comprising an oil cup and an atomizing nozzle, the oil cup and the atomizing nozzle are both arranged above the storage cabinet bottom belt chain, the atomizing nozzle is provided with a through inlet end, a gas-liquid mixing chamber and an outlet end, the inlet end of the atomizing nozzle is used to communicate with an external workshop compressed air pipeline, the atomizing nozzle is further provided with a liquid inlet passage, the liquid inlet passage is used to communicate with the oil cup and the gas-liquid mixing chamber, the outlet end of the atomizing nozzle is aligned directly above the storage cabinet bottom belt chain, and the spray width range of the outlet end is greater than or equal to the width of the storage cabinet bottom belt chain;

[0007] An air blowing passage communicating with the inlet end is provided in the atomizing nozzle, and an outlet direction of the air blowing passage is arranged at an angle to the vertical direction, so as to be used for blowing the bottom belt chain of the storage cabinet in advance.

[0008] Optionally, a first solenoid valve is provided between the inlet of the atomizing nozzle and the workshop compressed air pipeline, and a second solenoid valve is provided between the liquid inlet of the atomizing nozzle and the oil cup. The solenoid valves facilitate control of the flow rate and velocity of the lubricating oil and compressed air, thereby indirectly controlling the size and particle size of the spray.

[0009] Optionally, the switching frequencies of solenoid valves 1 and 2 are synchronized, and the switching frequencies are adapted to the frequency with which each link of the cabinet's bottom belt chain passes beneath the outlet port. By adjusting the frequency settings to the speed of the bottom belt chain, the links' connections are periodically lubricated, achieving precise lubrication while conserving lubricant.

[0010] Optionally, a peristaltic pump is provided between the liquid inlet passage of the atomizing nozzle and the oil cup. The oil supply speed can be controlled by providing the peristaltic pump.

[0011] Optionally, the outlet end of the atomizing nozzle includes two outlets, the spray directions of the two outlets are set at an angle and aligned with the lubrication points on both sides of the storage cabinet bottom belt chain. This further achieves precise lubrication based on the structural characteristics and actual lubrication requirements of the storage cabinet bottom belt chain.

[0012] Optionally, an air hole is provided on the top of the oil cup to balance the atmospheric pressure inside and outside the oil cup.

[0013] Optionally, the bottom of the atomizing nozzle is provided with an oblique surface, and the outlet of the air blowing passage is opened on the oblique surface.

[0014] Beneficial effects of the utility model:

[0015] 1. The utility model provides an oil cup and an atomizing nozzle, and the lubricating oil in the oil cup and the compressed air in the existing compressed air pipeline in the workshop enter the gas-liquid mixing chamber through the liquid inlet passage and the inlet end respectively for mixing. The high-pressure compressed air flow serves as the main power source and carrier to mix with the lubricating oil. The spray width range at the outlet end is greater than or equal to the width of the storage cabinet bottom belt chain, thereby achieving lubrication of the storage cabinet bottom belt chain, with good lubrication effect and low oil consumption. At the same time, the blowing passage is provided on the bevel surface. Before the outlet of the atomizing nozzle sprays lubrication, the blowing passage is used to blow away the dust on the chain in advance, thereby ensuring the cleanliness of the part to be lubricated, avoiding the mixing of impurities, and improving the service life of the chain.

[0022] The following describes the implementation of the present invention through specific embodiments. Those skilled in the art can understand the advantages and effects of the present invention from the content disclosed in this specification. It should be noted that the illustrations provided in the following embodiments are for illustrative purposes only and are only schematic diagrams, not actual drawings.

In order to better illustrate the embodiments of the present invention, some parts in the figures may be omitted, enlarged or reduced, and do not represent the dimensions of the actual product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the figures.

[0023] The same or similar numbers in the figures of the embodiments of the present invention correspond to the same or similar parts. In the description of the present invention, it should be understood that if the terms "up", "down", "left", "right", "front", "back", etc. indicate directions or positional relationships, they are based on the directions or positional relationships shown in the figures. This is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, the terms describing the positional relationship in the figures are only used for illustrative purposes and cannot be understood as limitations on the present invention. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0024] like Figures 1-4 The figure shows a cabinet bottom belt chain lubrication device according to the present invention, comprising an oil cup 1 and an atomizing nozzle 2. Both the oil cup 1 and the atomizing nozzle 2 are positioned above the cabinet bottom belt chain 3. The oil cup 1 is positioned higher than the atomizing nozzle 2 and is removably connected to the side of the cabinet body via a base or bracket. The atomizing nozzle 2 has a through-hole inlet 21, a gas-liquid mixing chamber 22, and an outlet 23. The inlet 21 of the atomizing nozzle 2 is connected to the external workshop compressed air pipeline. The atomizing nozzle 2 also has a liquid inlet passage 24. Lubricating oil enters the atomizing nozzle 2 through the liquid inlet passage 24 and then passes through a cavity surrounding the inlet to connect to the gas-liquid mixing chamber 22, ensuring effective mixing of the lubricating oil and compressed air.

[0025] In this embodiment, the liquid inlet passage 24 is used to connect the oil cup 1 and the gas-liquid mixing chamber 22. The lubricating oil in the oil cup 1 and the compressed air in the workshop compressed air pipeline enter the gas-liquid mixing chamber 22 through the liquid inlet passage 24 and the inlet end 21 respectively to be mixed. The compressed air serves as the power source for the formation of the spray. After the lubricating oil is mixed and atomized, it is sprayed out from the outlet end 23 of the atomizing nozzle 2. The outlet end 23 of the atomizing nozzle 2 is aligned with the top of the cabinet bottom belt chain 3. The spray width range of the outlet end 23 is greater than or equal to the width of the cabinet bottom belt chain 3, thereby achieving lubrication of the cabinet bottom belt chain 3.

[0026] In this embodiment, a beveled surface 26 is provided at the bottom of the atomizing nozzle 2, and an air blowing passage 25 connected to the inlet end is provided in the atomizing nozzle 2. The outlet direction of the air blowing passage 25 is set at an angle to the vertical direction. The outlet of the air blowing passage 25 is opened on the beveled surface 26, which is used to blow the chain 3 at the bottom of the storage cabinet in advance. The air blowing passage 25 is set on the beveled surface 26. Before the outlet of the atomizing nozzle 2 sprays lubrication, the dust on the chain is blown away in advance through the air blowing passage 25, thereby ensuring the cleanliness of the part to be lubricated, avoiding the mixing of impurities, and improving the service life of the chain.

[0027] In this embodiment, a solenoid valve 1 is installed between the inlet end 21 of the atomizing nozzle 2 and the workshop compressed air pipeline, and a solenoid valve 2 is installed between the liquid inlet passage 24 of the atomizing nozzle 2 and the oil cup 1. The solenoid valves facilitate control of the flow rate and velocity of the lubricating oil and compressed air, indirectly controlling the size and particle size of the spray.

[0028] In this embodiment, the switching frequencies of solenoid valves 1 and 2 are synchronized, and the switching frequencies are adapted to the frequency with which each link of the cabinet bottom belt chain 3 passes beneath the outlet port 23. Specifically, by adjusting the frequency settings to the speed of the cabinet bottom belt chain 3, the connecting parts of the links are periodically lubricated, achieving precise lubrication while conserving lubricating oil.

[0029] In this embodiment, a peristaltic pump 11 can also be installed between the liquid inlet passage 24 of the atomizing nozzle 2 and the oil cup 1. By installing a peristaltic pump and controlling the oil supply speed, the oil cup 1 can be placed in any convenient location. The peristaltic pump 11 actively supplies oil, ensuring a more effective misting effect. It should be understood that the lubrication device of the present invention can also operate even when the peristaltic pump 11 is not installed. In this case, the negative pressure generated by the compressed air passing through the gas-liquid mixing chamber 22 at high speed draws the lubricating oil from the liquid inlet passage 24, thereby performing spray lubrication.

[0030] In this embodiment, Figure 2 The outlet end of the atomizing nozzle 2 shown may include only one large outlet, which directly covers the lubrication points on both sides and is suitable for scenes with strong lubrication requirements; Figure 3 As shown, two outlets may also be included, and the spray directions of the two outlets are set at an angle and are aligned with the lubrication points on both sides of the chain 3 at the bottom of the storage cabinet.

[0031] Compared with ordinary transmission chains, the cabinet bottom belt chain 3 is usually composed of an inner link plate, an outer link plate, a chain pin, a roller, a roller shaft, etc. to form a chain link, which is then formed by multiple chain links connected in series. The parts that need to be lubricated are mainly the contact surface between the roller and the roller shaft, the contact surface between the inner chain plate and the roller, the contact surface between the two chain plates, and the pin shaft part in the middle.

[0032] Specifically, since the contact surface between the roller and the roller shaft and the middle pin shaft part are lubricated by lubricating oil, the core lubrication points are the gaps on both sides of the roller and the gap between the two chain plates. These two groups of gaps are symmetrically distributed on both sides of the chain, that is, the lubrication points on both sides of the cabinet bottom belt chain 3. The lubricating oil will penetrate into the remaining lubrication parts through the lubrication points on both sides.

[0033] In this embodiment, an air hole 12 is provided on the top of the oil cup 1 to balance the atmospheric pressure inside and outside the oil cup 1 and prevent the formation of a closed negative pressure cavity in the oil cup 1 that interferes with the outflow of lubricating oil.

[0034] The working principle of this utility model is as follows:

[0035] When using the lubricating device of the present invention, the oil cup 1 is filled with liquid chain oil, and the inlet end 21 of the atomizing nozzle 2 is connected to the external workshop compressed air pipeline. It should be noted that the side of the beveled surface 26 of the atomizing nozzle 2 must be in the front, that is, in the direction from which the chain 3 at the bottom of the storage cabinet runs. Figure 1 As shown, if the chain moves to the left, the beveled surface 26 faces right, so that compressed air is ejected through the blowing passage 25 to blow away the dust on the chain in advance.

[0036] Under the control of solenoid valves 1 and 2, the lubricating oil and compressed air in oil cup 1 enter gas-liquid mixing chamber 22 through liquid inlet passage 24 and inlet port 21, respectively, where they mix. The compressed air flowing through gas-liquid mixing chamber 22 at high speed acts as the power source for the spray, creating a high-speed turbulence in the chamber. This causes the compressed air and lubricating oil to mix and atomize, before being sprayed out of outlet port 23 of atomizing nozzle 2, thereby lubricating the cabinet bottom belt chain 3. Before the lubricating spray is applied at the outlet of atomizing nozzle 2, air passage 25 is used to preemptively purge any dust from the chain, ensuring the cleanliness of the lubricated area, preventing the intrusion of impurities, and thus extending the service life of the cabinet bottom belt chain 3.

[0037] During this process, the solenoid valve's switching frequency, coordinated with the operating speed of the cabinet's bottom belt chain 3, allows the outlet end 23 of the atomizing nozzle 2 to intermittently and precisely lubricate the lubrication points on both sides, saving lubricating oil and compressed air. In emergency situations, solenoid valves 1 and 2 can be kept open to provide high-intensity, full lubrication of the cabinet's bottom belt chain 3 to ensure effective lubrication.

[0038] The above embodiments are intended only to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art will appreciate that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and such modifications or equivalent substitutions shall be encompassed by the claims of the present invention. The techniques, shapes, and structural portions not described in detail in the present invention are well known.
