Description

Technical Field

[0001] This utility model relates to the field of sprocket technology, and in particular to a high-efficiency disassembly and cleaning device for large pitch sprockets. Background Technology

[0002] In industrial production, large-pitch sprockets are critical transmission components, and their cleaning and maintenance are essential. Traditional methods for cleaning large-pitch sprockets have many drawbacks. Early methods relied heavily on manual cleaning, requiring workers to use brushes and cleaning agents to scrub each sprocket individually. This method was not only labor-intensive but also extremely inefficient; a skilled worker could only clean a limited number of sprockets per day. With technological advancements, simple mechanical cleaning equipment emerged, such as single-station fixed cleaning devices that fix the sprockets in a single position and clean them by spraying cleaning agents. However, these devices can only clean one sprocket at a time, and the loading and unloading process is cumbersome and time-consuming. This is especially problematic for large-pitch sprockets, which are large and heavy, making manual handling difficult and requiring extended drying times after cleaning, significantly impacting production schedules. In mass production scenarios, the cleaning efficiency requirements for large-pitch sprockets are even higher. Existing equipment struggles to meet the demands of enterprises for efficient cleaning, failing to enable rapid loading and unloading of sprockets for batch cleaning operations, thus severely limiting production efficiency and capacity expansion. Therefore, developing a device that can quickly load and unload large-pitch sprockets and achieve batch cleaning to reduce loading and unloading time and improve cleaning efficiency has become an urgent problem to be solved in the industry. Utility Model Content

[0003] The present invention aims to solve the above-mentioned defects and provide a high-efficiency disassembly and cleaning device for large pitch sprockets.

[0004] In order to overcome the defects in the background technology, the technical solution adopted by this utility model to solve its technical problem is: a high-efficiency disassembly and cleaning device for large pitch sprockets, including a main box with an open structure at the top. Four lifting mechanisms are vertically installed inside the box, and the lifting mechanisms are arranged in pairs opposite each other. A lifting plate is connected between the two lifting mechanisms in each pair, so that the lifting plate can be smoothly moved up and down by driving the lifting mechanism. Two bearing turntables are arranged parallel to each other and rotating relative to each other on the lifting plate.

[0005] The bearing shaft has at least one sprocket mounted on it, and its two ends are stably supported by two bearing turntables.

[0006] A rotary drive mechanism is used to drive the bearing shaft to rotate, and it is connected to a slide rail locking device on the main housing, so that the rotary drive mechanism can move and adjust its position freely up and down through the slide rail locking device.

[0007] Further improvements include binding the bearing shaft and the two bearing turntables together with a binding strap around the outermost edge of the bearing shaft and the two bearing turntables, and the binding strap moves with the rotation of the bearing shaft and the two bearing turntables, and the binding strap is embedded in a positioning groove circumferentially opened on the outer edge of the bearing turntable.

[0008] Further improvements include the rotary drive mechanism comprising a lifting bracket and a transmission motor mounted on the lifting bracket. A connecting shaft is rotatably mounted on the lifting bracket, with one end of the connecting shaft connected to a driven gear and the other end connected to a main drive gear. The output end of the transmission motor is connected to a driving gear. The driving gear and the driven gear are connected by a chain, thereby enabling the driving gear and the driven gear to rotate synchronously. When the lifting bracket moves down to a predetermined position, the main drive gear meshes with a driven gear ring mounted on the bearing shaft.

[0009] Further improvements include the installation of an ultrasonic vibration generator inside the main housing.

[0010] The beneficial effects of this utility model are as follows: In this design, the bearing shaft can be loaded with multiple large-pitch sprockets. With the help of the quick installation design, the material can be loaded quickly. With the help of the lifting mechanism and the rotary drive mechanism, multiple sprockets can be cleaned simultaneously, and the loading and unloading time is greatly shortened, which meets the needs of large-scale production and effectively improves the enterprise's production capacity. The bearing shaft and the bearing turntable are bound by the binding strap. The binding strap is embedded in the positioning groove to avoid axial displacement, ensure the stable rotation of the sprocket during cleaning, and improve the consistency of the cleaning effect.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art without creative effort in accordance with the embodiments of the basic utility model are within the scope of protection of this utility model.

[0019] refer to Figure 1 and Figure 2 A high-efficiency disassembly and cleaning device for large pitch sprockets includes a main housing 1 with an open structure at the top. Four lifting mechanisms 4 are vertically installed inside the housing, and the lifting mechanisms 4 are arranged in pairs opposite each other. A lifting plate 7 is connected between the two lifting mechanisms 4 in each pair, so that the lifting plate 7 can be moved up and down smoothly by driving the lifting mechanism 4. Two load-bearing turntables 8 are arranged parallel to each other and rotate relative to each other on the lifting plate 7.

[0020] The bearing shaft 5 has at least one sprocket mounted on it, and its two ends are stably supported by two bearing turntables 8.

[0021] The rotary drive mechanism 3 is used to drive the bearing shaft 5 to rotate, and it is connected to the slide rail locking device 2 provided on the main housing 1 so that the rotary drive mechanism 3 can move and adjust its position freely up and down through the slide rail locking device 2.

[0022] This design loads multiple large-pitch sprockets on the bearing shaft 5, and the bearing shaft 5 can be quickly placed on the bearing turntable 8. In conjunction with the lifting mechanism 4 and the rotary drive mechanism 3, the bearing shaft 5 is rotated to achieve batch cleaning, thereby reducing loading and unloading time and improving cleaning efficiency.

[0023] In this embodiment, reference Figure 2 and Figure 3 The bearing shaft 5 and the two bearing turntables 8 are bound together by a binding strap 9 around their outermost edges. The binding strap 9 moves with the rotation of the bearing shaft 5 and the two bearing turntables 8, and is embedded in the positioning groove 10 circumferentially opened on the outer edge of the bearing turntable 8. This ingenious design effectively restricts the binding strap 9 from axial displacement along the bearing shaft 5 during rotation, ensuring the stability of the connection.

[0024] In this embodiment, reference Figure 4The rotary drive mechanism 3 includes a lifting bracket 301 and a transmission motor 303 mounted on the lifting bracket 301. A connecting shaft 306 is rotatably mounted on the lifting bracket 301, with one end of the connecting shaft 306 connected to a driven gear 302 and the other end connected to a main drive gear 307. The output end of the transmission motor 303 is connected to a driving gear 304, which drives the driving gear 304 to rotate. The driving gear 304 and the driven gear 302 are connected by a chain 305. This allows the driving gear 304 and the driven gear 302 to rotate synchronously. When the lifting bracket 301 moves down to a predetermined position, the main drive gear 307 meshes with the driven gear ring 6 mounted on the bearing shaft 5, thereby efficiently driving the bearing shaft 5 to rotate through the transmission motor 303.

[0025] In this embodiment, an ultrasonic vibration generator 11 is provided inside the main housing 1. The ultrasonic vibration generator 11 can greatly improve the cleaning effect of the sprocket.

[0026] Working principle: Multiple sprockets are loaded on the bearing shaft 5. After completion, the two ends of the bearing shaft 5 are placed above the two bearing turntables 8 by the overhead crane. The rotary drive mechanism 3 is moved down by the control slide rail locking device 2, so that the main drive gear 307 meshes with the driven gear ring 6, thereby driving the bearing shaft 5 to rotate through the transmission motor 303, thus improving the cleaning effect.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
