Description
Technical Field
[0001] The utility model relates to a lubricating device, in particular to an automatic lubricating device for a storage cabinet conveying chain track. Background Art
[0002] At present, the material conveying methods of various storage cabinets for silk thread in the field of cigarettes all rely on the conveyor chain running on the track to achieve the purpose of conveying materials. The function of the silk thread storage cabinet is to improve the uniformity of tobacco leaves and tobacco shreds absorbing liquid and moisture, and balance the production connection of each process. Therefore, the storage cabinet has a large daily load and is used frequently. Long-term operation and the influence of the humid environment of the storage room will cause the roller shaft and the inner sleeve of the roller to rust, resulting in some rollers not rotating. During operation, the roller will generate friction with the track, causing dragging problems on the track, abnormal noises will occur, aggravating the wear of the conveyor chain, and then the roller chain plate will fall off, the conveyor chain will be disjointed, and other problems will occur. Once the conveying system fails, it will cause shutdown and material interruption, and manual loading and dumping of tobacco shreds will be required, causing tobacco shreds to be broken, seriously affecting product quality. Moreover, the installation and maintenance process in the humid and hot storage room is time-consuming and labor-intensive, increasing labor intensity, and there is a risk of heatstroke for maintenance personnel.
[0003] The existing mode of lubricating the conveyor chain is to use liquid spray (containing oily substances) to spray in a mist form, which needs to be done manually each time. If you are not careful, it will be sprayed onto the bottom belt of the storage cabinet or the material, causing pollution to the tobacco leaves (shreds) and easily generating oil smoke and yellow spot smoke. Moreover, the liquid spray will dry up after a short time of lubrication. The amount of lubricant for one circle of the chain is also very large, which is time-consuming and laborious. Moreover, the spraying requirements for the staff are also very strict. Utility Model Content

DETAILED DESCRIPTION
[0015] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.
[0016] Embodiments of the present utility model: Figure 1 and Figure 2 As shown, an automatic lubrication device for a storage cabinet conveyor chain track includes a bracket 10, which serves to support a horizontal material leveling device. The lower end of the bracket 10 is fixedly connected to the chain plates 14 on both sides of the storage cabinet conveyor chain track 13. A horizontal material leveling device is fixedly arranged on the top of the bracket 10. A discharge port 15 is arranged at the bottom of one end of the horizontal material leveling device, and a silo 4 is fixedly arranged on the top of the other end of the horizontal material leveling device. The silo 4 is connected to the inside of the horizontal material leveling device. A plurality of rollers 12 are rotatably installed between the chain plates 14, and the rollers 12 are rollingly connected to the top surface of the storage cabinet conveyor chain track 13.
[0017] In this embodiment, the bracket 10 is specifically composed of four support plates, two support plates are respectively arranged on both sides of the horizontal material scrambling device, the upper end of the support plate is fixedly connected to the horizontal material scrambling device, and a threaded hole is provided at the lower end of the support plate. The lower end of the support plate is fixed to the chain plate 14 using a fixing screw 11. Of course, a threaded hole is also required on the chain plate 14 for installing the screw 11. The chain plate 14 and the roller 12 are both prior arts, and chain plates 14 are arranged on both sides of the storage cabinet conveying chain track 13, wherein two support plates are fixed to the chain plate 14 on one side of the storage cabinet conveying chain track 13, and the other two support plates are fixed to the chain plate 14 on the other side of the storage cabinet conveying chain track 13.
[0018] The silo 4 is filled with graphite powder, which leaks into the horizontal material mixing device through the silo 4, is evenly spread and transported by the horizontal material mixing device, and evenly falls onto the storage cabinet conveyor chain track 13 through the discharge port 15. The discharge port 15 is specifically a funnel-shaped structure, and the discharge end of the discharge port 15 is aligned with the middle of the top surface of the storage cabinet conveyor chain track 13. When the roller 12 rolls on the storage cabinet conveyor chain track 13, it rolls the graphite powder to form an oil film to achieve a lubricating effect.
[0019] In a specific embodiment, the horizontal material leveling device includes a cylinder 1, a rotating shaft 3 and a variable frequency motor 9. The rotating shaft 3 is rotatably installed in the cylinder 1, and a screw 2 is welded and fixed on the rotating shaft 3. The variable frequency motor 9 is fixedly installed on the outer wall of one end of the cylinder 1, and the rotating shaft of the variable frequency motor 9 is fixedly connected to one end of the rotating shaft 3 through a coupling.
[0020] The coupling is a common component in the art, which is not shown in the figure. When the frequency conversion motor 9 is working, it drives the rotating shaft 3 to rotate. The auger 2 on the rotating shaft 3 is used to spread the graphite powder evenly and transport it in the direction of the discharge port 15. In order to ensure the smooth rotation of the rotating shaft 3, it is preferred that a second bearing seat 16 is provided at both ends of the cylinder 1, and the two ends of the rotating shaft 3 are rotatably connected to the cylinder 1 through the second bearing seat 16.
[0021] Furthermore, the silo 4 is communicated with the top of one end of the cylinder 1, the discharge port 15 is communicated with the bottom of the other end of the cylinder 1, a roller 5 is rotatably installed at the bottom of the silo 4, a servo motor 6 is fixedly provided on the outer wall of one end of the silo 4, and the output shaft of the servo motor 6 is fixedly connected to one end of the rotating shaft of the roller 5 through a coupling (not shown in the figure).
[0022] When the servo motor 6 is working, it drives the roller 5 to rotate, and the rotation of the roller 5 can play the role of turning the graphite powder to prevent the graphite powder from accumulating in the silo 4 and being unable to fall. Similarly, in order to ensure that the roller 5 can rotate smoothly, a first bearing seat 8 is fixed on the side wall of the silo 4, and the rotating shaft of the roller 5 is rotatably connected to the silo 4 through the first bearing seat 8.
[0023] Preferably, the longitudinal section of the silo 4 is a right-angled trapezoid with a larger upper portion and a smaller lower portion, and a vibration motor 7 is installed on the inclined side of the silo 4. Designing the silo 4 as a right-angled trapezoidal structure with a larger upper portion and a smaller lower portion in longitudinal section is conducive to the falling of graphite powder, and through the cooperation of this structure and the vibration motor 7, the graphite powder can slide down the inclined surface to prevent retention.
[0024] The working principle of the utility model is as follows: when the storage cabinet is in an empty state and the storage cabinet conveying chain track 13 needs lubrication, the staff controls the storage cabinet to work and moves the chain plate 14. When the four chain plates 14 with threaded holes move to one end of the storage cabinet conveying chain track 13, the equipment is stopped, and the automatic lubrication device of the storage cabinet conveying chain track is installed on the four chain plates 14 with threaded holes through four fixing screws 11. Graphite powder is poured into the silo 4, and then the storage cabinet is started, and the servo motor 6, the vibration motor 7 and the frequency conversion motor 9 are turned on at the same time. The chain plate 14 moves synchronously with the automatic lubrication device of the storage cabinet conveying chain track. At the same time, the servo motor 6 drives the roller 5 to rotate. The speed is adjusted according to the looseness of the graphite powder in the silo 4 and the principle of not blocking the cylinder 1. The manual program intervention adjustment is performed. Once it is set, no adjustment is required. At the same time, the vibration motor 7 generates a vibration frequency to effectively loosen the graphite powder on the inclined wall of the silo 4 to prevent the graphite powder from being retained and sliding onto the roller 5. The loose graphite powder in the silo 4 enters the closed cylinder 1 and falls on the rotating shaft 3 and the auger 2 driven by the variable frequency motor 9. As the auger 2 rotates, the graphite powder is transferred to the discharge port 15 and falls to the upper part of the storage cabinet conveyor chain track 13. The speed and amount of graphite powder falling to the upper part of the storage cabinet conveyor chain track 13 are achieved by manually intervening in the program to adjust the number of revolutions of the variable frequency motor 9. Once adjusted, no adjustment is required. The cylinder 1 moves forward along the chain plate 14, and the graphite powder in the cylinder 1 pours to the upper part of the storage cabinet conveyor chain track 13 along the length direction. As the roller 12 on the chain plate 14 rolls on the storage cabinet conveyor chain track 13, an oil film is formed to lubricate the storage cabinet conveyor chain track 13. When the storage cabinet conveyor chain track 13 is fully lubricated, the storage cabinet is controlled to stop, and the servo motor 6, the vibration motor 7 and the variable frequency motor 9 are turned off at the same time, and the automatic lubrication device of the storage cabinet conveyor chain track is removed from the chain plate 14. It should be noted that the automatic lubrication device for the storage cabinet conveyor chain track can be powered by an external power supply for the servo motor 6, the vibration motor 7 and the variable frequency motor 9, or a battery can be set to power the servo motor 6, the vibration motor 7 and the variable frequency motor 9, and the battery is not shown in the figure.
[0025] The above describes in detail the structure, features and effects of the utility model based on the embodiments shown in the drawings. The above is only a preferred embodiment of the utility model, but the utility model is not limited to the scope of implementation shown in the drawings. Any changes made in accordance with the concept of the utility model, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and the drawings, should be within the protection scope of the utility model.
