Description

Technical Field

[0001] This utility model relates to the field of sprocket device technology, and in particular to a sprocket device for a roller mill. Background Technology

[0002] A double-roll crusher is a device that uses two rotating rollers to crush materials. The rollers are equipped with toothed structures that clamp the material between them through relative rotation. Double-roll crushers are widely used in sand and gravel plants, primarily for crushing materials with high hardness, such as limestone, coal, and ore.

[0003] Roller mills typically use drive belts for power transmission. However, when these mills crush sand and gravel during operation, they generate vibrations. Since the drive belt operates through friction, the load between the rotating wheel and the drive belt is relatively high. Under the influence of vibration, the tension load on the drive wheel can easily increase further, thus affecting its service life. To address this issue, we propose a sprocket device for roller mills. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies mentioned in the background section by proposing a sprocket device for a roller mill.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sprocket device for a roller mill includes a roller mill body. A first roller is provided on one side of the top end of the roller mill body, and a second roller is provided on the other side of the top end of the roller mill body. An air inlet is provided between the first roller and the second roller. A first multi-stage gear machine is provided at one end of the roller mill body, and a second multi-stage gear machine is provided at the other end of the roller mill body. The first multi-stage gear machine is adapted to the second roller, and the second multi-stage gear machine is adapted to the first roller. A sprocket body is inserted into the ends of both the first roller and the second multi-stage gear machine. The two sets of sprocket bodies are fitted together, and a chain drive is sleeved on the outside of the sprocket body.

[0007] It can be modified to use chain drive, with the two sets of chains working together to provide a certain buffer space, thereby reducing the load on the sprocket and increasing its service life.

[0008] Preferably, a limit slot is provided at the same position on the inner wall of the first roller output shaft and the sprocket body, and a limit pin is inserted into the inside of the limit slot;

[0009] The limit pin can be inserted into the limit slot, thereby improving the stability between the sprocket body and the output shaft of the first roller.

[0010] Preferably, the side wall of the limiting pin is provided with a movable slot, the inside of the movable slot is provided with a limiting top rod, and the inner wall of the upper limiting slot of the sprocket body is provided with a hole that matches the limiting top rod.

[0011] This can prevent the limit pin from disengaging during rotation, thus improving the transmission effect of the sprocket body.

[0012] Preferably, both ends of the limiting top rod are provided with limiting sliders, and both sides of the inner wall of the movable slot are provided with limiting grooves, and the limiting sliders extend into the interior of the limiting grooves.

[0013] This can improve the stability of the sliding of the limit rod and prevent it from coming off track.

[0014] Preferably, a threaded rod is inserted into the end of the limiting top rod, the threaded rod is threadedly connected to the limiting top rod, and a transmission gear is provided at the end of the threaded rod, the other end of the transmission gear being movably connected to the interior of the movable slot;

[0015] The rotation of the threaded rod can drive the movement of the limiting rod, making the movement of the limiting rod more convenient.

[0016] Preferably, a transmission rack is inserted into the end of the limiting pin. The transmission rack is L-shaped and located directly above the transmission gear. The transmission rack meshes with the transmission gear.

[0017] It can make the transmission rack move and drive the transmission gear to rotate, making the rotation of the transmission gear more convenient.

[0018] Preferably, a tension spring is provided at one end of the transmission rack, and the other end of the tension spring is fixedly connected to the inner wall of the limiting pin;

[0019] This allows the transmission rack to be pulled, causing the tension spring to unfold. When the transmission rack is released, the tension spring causes the transmission rack to return to its original position, thus facilitating subsequent reuse.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] 1. This utility model allows two sets of tension springs to be brought close together and then connected by two sets of chains, thereby improving the rotation effect of the chains. At the same time, the first roller or the second multi-stage gear will not affect the transmission effect when vibrating, thus reducing the load on the sprocket body transmission and increasing the service life of the device.

[0022] 2. This utility model allows the limiting pin to be embedded inside the limiting slot to increase stability. When it is necessary to remove the limiting pin, the transmission rack can be pulled, which will cause the transmission rack to drive the transmission gear to rotate, and then the transmission gear will drive the limiting push rod to move, so that the limiting push rod will disengage from the insertion hole inside the limiting slot, thereby allowing the limiting pin to disengage from the limiting slot and completing the disassembly and replacement of the sprocket body.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Reference Figure 1-4The illustrated sprocket device for a roller mill has a first roller 2 on one side of the top of the roller mill body 1, and a second roller 3 on the other side of the top of the roller mill body 1. An air inlet 4 is provided between the first roller 2 and the second roller 3. A first multi-stage gear machine 5 is provided at one end of the roller mill body 1, and a second multi-stage gear machine 6 is provided at the other end of the roller mill body 1. The first multi-stage gear machine 5 and the second roller 3 are adapted to each other, so that the second multi-stage gear machine 6 and the first roller 2 are also adapted to each other. Subsequently, the sprocket device for the first roller 2 and the second roller 3... The ends of the second multi-stage gear machine 6 are all fitted with sprocket bodies 7, and the two sets of sprocket bodies 7 are in close contact with each other. At the same time, a chain drive is sleeved on the outside of the sprocket body 7. The output shaft of the first roller 2 and the inner wall of the sprocket body 7 are both provided with limit slots 8, so that limit pins 9 are inserted into the limit slots 8. The side wall of the limit pins 9 is provided with a movable slot 10, so that a limit rod 11 is inserted into the movable slot 10. Then, the inner wall of the limit slot 8 of the sprocket body 7 is provided with a hole that matches the limit rod 11.

[0030] For a detailed explanation of the limiting pin 9 in this embodiment, please refer to [link / reference]. Figure 3 and Figure 4 Limiting sliders 12 are provided at both ends of the limiting top rod 11. Then, limiting grooves 13 are provided on both sides of the inner wall of the movable slot 10. The limiting sliders 12 extend into the interior of the limiting grooves 13. At the same time, a threaded rod 14 is inserted into the end of the limiting top rod 11, so that the threaded rod 14 is threadedly connected to the limiting top rod 11. The end of the threaded rod 14 is provided with a transmission gear 15. The other end of the transmission gear 15 is movably connected to the interior of the movable slot 10, so that a transmission rack 16 is inserted into the end of the limiting pin 9. The transmission rack 16 is L-shaped and located directly above the transmission gear 15, so that the transmission rack 16 and the transmission gear 15 mesh with each other. The end of the transmission rack 16 is provided with a tension spring 17, so that the other end of the tension spring 17 is fixedly connected to the inner wall of the limiting pin 9.

[0031] Working principle: In use, the chain is sleeved on the outside of the sprocket body 7, so that the first roller 2 and the second roller 3 can transmit power. This allows for a certain buffer space between the second multi-stage gear machine 6 and the first roller 2, thereby improving the service life of the sprocket body 7. At the same time, during installation, the sprocket body 7 can be inserted into the limiting groove 8, so that the limiting top rod 11 is inserted into the insertion hole for limiting, thereby preventing the sprocket body 7 from shaking or falling off, resulting in better performance of the sprocket body 7.

[0032] When it is necessary to disassemble and replace the sprocket body 7, the transmission rack 16 can be pulled, causing the transmission rack 16 to drive the transmission gear 15 to rotate, thereby causing the transmission gear 15 to drive the threaded rod 14 to rotate. The threaded rod 14 drives the limiting rod 11 to move, thereby causing the limiting rod 11 to disengage from the inner hole of the sprocket body 7, so that the limiting pin 9 can disengage from the inner hole of the limiting groove 8. Then the sprocket body 7 can be disassembled and replaced, resulting in better performance of the sprocket body 7.
