Description

Technical Field

[0001] This utility model belongs to the field of mixing equipment for coatings, paints and the like, and particularly relates to an automatic lubrication structure that can periodically apply oil to the bevel gears on the internal support of a rotary mixer. Background Technology

[0002] Currently, the mixing machines used in the coatings industry are divided into vibratory mixers and rotary mixers.

[0003] A double rotary mixer is a device for mixing or homogenizing paints, varnishes, and similar substances. It enables a container containing paints, varnishes, and similar substances—referred to as a paint container—to rotate around its geometric center line while simultaneously rotating around a rotation axis perpendicular to the geometric center line of the container. This simultaneous rotation and revolution achieves the purpose of double-rotation homogenization of the paint. For example, patent CN201510122899.9 describes an unbalanced double-rotary paint mixer. A rotary spindle support is fixed to the frame, and the rotary spindle is fitted into the shaft hole of the support. An upper bearing seat and a lower bearing seat are fixed to the right end of the rotary spindle. Guide rails are fixed to both sides of the upper and lower bearing seats. The upper and lower ends of the two guide rails are fixedly connected by an upper frame plate and a lower frame plate, respectively. Thus, the upper and lower ends of the two guide rails are fixedly connected by the upper and lower frame plates, and the middle of the two guide rails is fixedly connected by the upper and lower bearing seats, forming a guide rail frame. The guide rail frame is divided into an upper guide rail frame and a lower guide rail frame by the rotary spindle. Parallel to the guide rail frame... A rotatable, two-section, reverse-threaded clamping screw is provided. The upper and lower support arms respectively engage with the guide rail pair of the guide frame and with the screw pair of the clamping screw, forming an upper support arm on the upper guide frame that can move up and down along it, and a lower support arm on the lower guide frame that can also move up and down along it. Moving the upper and lower support arms towards each other causes the upper pressure plate mounted on the upper support arm and the lower pressure plate mounted on the lower support arm to press or release the barrel body. The upper pressure plate is mounted on the upper support arm via an upper pressure plate shaft, and the lower pressure plate is mounted on the lower support arm via a lower pressure plate shaft. The upper and lower pressure plate shafts are coaxial, ensuring that the upper and lower pressure plates can rotate coaxially. The upper guide frame is equipped with a rotatable spline. A small bevel gear is fixed at the lower end of the guide shaft 7, which meshes with a large bevel gear on a support fixed to the frame. A drive pulley, slidably sleeved on the splined guide shaft, drives a driven pulley fixed to the upper pressure plate shaft to rotate via a belt. This, in turn, drives the upper pressure plate to rotate via the upper pressure plate shaft. When the upper and lower pressure plates press the barrel together, the barrel's axis coincides with the upper pressure plate's axis. The upper pressure plate's axis is defined as follows: when the upper pressure plate is circular, the axis perpendicular to the center of the circular plate is the upper pressure plate axis; the lower pressure plate's axis is defined the same way. When the upper pressure plate is not circular, during operation, the paint barrel is placed in the grooves of the upper and lower pressure plates, with the barrel's axis passing through the upper and lower pressure plates. The pressure plate is the axis of the upper pressure plate. Of course, the axis of the barrel is also the axis of the lower pressure plate. In short, when the upper pressure plate is not disc-shaped, the axis of the barrel is the axis of both the upper and lower pressure plates. The lower pressure plate rotates around the axis of the upper pressure plate with the upper pressure plate. During operation, the aforementioned rotary spindle can drive the entire guide rail frame and the accessories mounted on it to rotate along the axis of the rotary spindle, which is called the first-dimensional rotation. During operation, the upper pressure plate is driven to rotate around the axis of the upper pressure plate through the spline guide shaft, and the lower pressure plate is driven to rotate around the axis of the lower pressure plate through the compressed paint barrel, which is called the second-dimensional rotation. The first-dimensional rotation and the second-dimensional rotation are superimposed to form a double rotation. The double rotation formed by the superposition of the first-dimensional rotation and the second-dimensional rotation is unbalanced.The paint bucket generates two mutually perpendicular rotations: rotation on its own axis and revolution around the sun. The paint inside the bucket is driven by these rotations, resulting in an effective mixing motion and thus achieving the desired mixing effect.

[0004] In the above structure, the small bevel gear meshes with the large bevel gear of the support fixed on the frame for transmission. This high-speed transmission requires lubrication and heat dissipation of the bearing supporting the large bevel gear. It is necessary to apply grease or lithium-based grease to this area regularly. However, since this structure is located inside the protective housing, it is relatively difficult to add lubricant. Moreover, the impact of not adding lubricant on the device at the beginning is not particularly obvious. Over time, minor structural wear will occur without being noticed. Therefore, it is necessary to avoid the above situation. Utility Model Content

[0005] The technical problem to be solved by this utility model is: how to conveniently add lubricant. Therefore, an automatic lubrication structure is provided that can periodically apply oil to the bevel gears on the internal support of a rotary mixer.

[0006] To solve the above problems, this utility model is achieved through the following technical solution: An automatic lubrication structure for the bevel gear on the internal support of a rotary mixer includes a mounting base plate. A motor is fixedly mounted on the surface of the mounting base plate. A drive synchronous pulley is fixedly connected to the motor shaft of the motor. The drive synchronous pulley and the driven synchronous pulley are connected in a transmission connection. A plunger-type grease gun is also fixed on the mounting base plate. The plunger rod of the plunger-type grease gun is located inside the driven synchronous pulley, and the outer cylindrical surface of the plunger rod of the plunger-type grease gun is connected to the inner surface of the driven synchronous pulley through a threaded pair. The grease outlet of the plunger-type grease gun is fixedly connected to the grease nipple of the small bevel gear and / or the large bevel gear through a pipeline.

[0007] The driven synchronous pulley is mounted in a bearing housing via a bearing, and the bearing housing is mounted on the surface of the mounting base plate.

[0008] A limiting groove parallel to the plunger rod of the plunger-type grease gun is formed on the mounting base plate. A piston rod holder is fixedly installed on the plunger rod of the plunger-type grease gun, and a part of the piston rod holder is located in the limiting groove.

[0009] A retaining rod is provided on the mounting base plate. The retaining rod is parallel to the axis of the plunger rod of the plunger-type grease gun. A through hole is opened on the piston rod holder, and the through hole is fitted onto the outer circular surface of the retaining rod.

[0010] An upper position sensor and a lower position sensor are respectively installed on the mounting base plate. When the grease gun is full, the plunger rod of the plunger grease gun approaches the upper position sensor. When the grease gun is almost empty, the plunger rod of the plunger grease gun approaches the lower position sensor. The lower position sensor is connected to the controller.

[0011] A counting sensor is also installed on the surface of the mounting base plate, and a magnet is installed on the active synchronous pulley.

[0012] Compared with the prior art, the present invention has the following advantages: by driving the driven synchronous pulley to rotate by the motor, the plunger rod of the plunger-type grease gun moves linearly, so that the plunger-type grease gun continuously adds lubricant to the small bevel gear and / or the large bevel gear, thereby avoiding the wear and tear of the parts and extending the service life of the equipment.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0016] like Figure 3 , Figure 4As shown, the automatic lubrication structure 100 of the bevel gear on the internal support of the rotary mixer includes a mounting base plate 1. A motor 2 is fixedly mounted on the surface of the mounting base plate 1. A driving synchronous pulley 3 is fixedly connected to the motor shaft of the motor 2. The driving synchronous pulley 3 is connected to the driven synchronous pulley 7 through a synchronous belt 8. The driven synchronous pulley 7 is disposed in a bearing seat 5 through a bearing 6. The bearing seat 5 is mounted on the surface of the mounting base plate 1. It should be noted that the upper section of the driven synchronous pulley 7 protrudes above the inner ring of the bearing 6.

[0017] A plunger-type grease gun 9 is also fixed on the mounting base plate 1. The plunger rod of the plunger-type grease gun 9 is located inside the driven synchronous pulley 7, and the outer cylindrical surface of the plunger rod of the plunger-type grease gun 9 is connected to the inner surface of the driven synchronous pulley 7 through a threaded pair. The rotational movement of the driven synchronous pulley 7 drives the plunger rod of the plunger-type grease gun 9 to move linearly. The grease outlet of the plunger-type grease gun 9 is fixedly connected to the grease nozzle 14 of the small bevel gear and / or large bevel gear 13 through a pipeline. Here, the small bevel gear and / or large bevel gear 13 and the grease nozzle 14 are all components of the original equipment.

[0018] To limit the rotation of the plunger rod of the plunger-type grease gun 9, a limiting groove 1-1 parallel to the plunger rod of the plunger-type grease gun 9 is formed on the mounting base 1. A piston rod holder 10 is fixedly mounted on the plunger rod of the plunger-type grease gun 9, with a portion of the piston rod holder 10 located within the limiting groove 1-1. As the plunger rod of the plunger-type grease gun 9 moves axially, the piston rod holder 10 slides within the limiting groove 1-1. Thus, the cooperation between the piston rod holder 10 and the limiting groove 1-1 provides the limiting effect of the sliding block groove, allowing for equivalent substitution. In some structures, the limiting groove 1-1 is replaced by a retaining rod set on the mounting base 1. The retaining rod is parallel to the axis of the plunger rod of the plunger-type grease gun 9, and a through hole is formed on the piston rod holder 10, which fits onto the outer circumference of the retaining rod. This structure also achieves limiting.

[0019] To test whether the grease gun 9 needs to be filled, an upper position sensor 11 and a lower position sensor 12 are respectively installed on the mounting base plate 1. When the grease gun 9 is full, the plunger rod of the grease gun 9 approaches the upper position sensor 11; when the grease gun 9 is almost empty, the plunger rod of the grease gun 9 approaches the lower position sensor 12. The lower position sensor 12 sends a signal to the controller, and the controller sends relevant prompts to the operator through other components, reminding the operator to add grease to the grease gun 9. The controller adds grease to the bevel gear at timed and quantitative intervals to maintain the stable operation of the device.

[0020] Even better, a counting sensor 4 is also provided on the surface of the mounting base plate 1, and a magnet 3-1 is mounted on the drive synchronous pulley 3. The counting sensor 4 detects the number of rotations of the drive synchronous pulley 3 by detecting the magnet 3-1 on the drive synchronous pulley 3. When the magnet 3-1 rotates with the drive synchronous pulley 3, and when the magnet 3-1 is opposite to the counting sensor 4, the counting sensor 4 senses the magnet 3-1. At this time, the counting sensor 4 sends the number of rotations to the controller to calculate whether the single refueling is completed, so as to control the start and stop of the motor 2.

[0021] The working principle of this utility model is as follows: Motor 2 activates, driving the active synchronous pulley 3 to rotate, which in turn drives the driven synchronous pulley 7 to rotate. The rotation of the driven synchronous pulley 7 causes the plunger rod of the plunger-type grease gun 9 to move linearly, thus dispensing grease. The entire process is controlled by a controller, which can be programmed with a timer (existing technology). This invention significantly reduces the need for manual opening of the casing to add grease or lithium-based grease while ensuring regular automatic application of grease or lithium-based grease to the large bevel gear.

[0022] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
