Description

Technical Field

[0001] This utility model relates to the field of irradiation processing equipment technology, and in particular to an irradiator with an adjustable speed ratio rotation-revolution coupling mechanism. Background Technology

[0002] Irradiation technology is widely used in food sterilization and material modification. To ensure the consistency of irradiation dose and the uniformity of treatment effect, the object to be irradiated needs to revolve around the irradiation source while maintaining its own rotation. Most existing irradiators use a fixed gear transmission chain to achieve this composite motion. Although this rigid connection method is structurally stable, the ratio of the rotation speed to the revolution speed is constant. It cannot be flexibly adjusted according to the material characteristics of different objects and the specific irradiation process requirements, which makes it difficult to achieve the optimal irradiation uniformity and limits the applicability and processing efficiency of the equipment.

[0003] Although some equipment attempts to introduce friction drive structures to achieve stepless speed regulation, conventional friction drive mechanisms lack dynamic pressure compensation mechanisms. After long-term operation, wear occurs on the surface of the friction wheel or fatigue relaxation of the elastic elements, resulting in a decrease in the normal pressure between the friction contact surfaces, which in turn causes transmission slippage. Slippage not only causes speed fluctuations and reduced transmission efficiency, but also leads to uneven distribution of irradiation dose, seriously affecting the final quality of the product. Moreover, existing adjustment methods often require shutdown and disassembly operations, making it impossible to achieve continuous linear and precise speed regulation during operation.

[0004] Therefore, this invention proposes an irradiator with an adjustable speed ratio rotation-revolution coupling mechanism to address the shortcomings of the prior art. Utility Model Content

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 based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0021] Example: Please refer to Figures 1 to 6 This utility model provides an irradiator with an adjustable speed ratio rotation-revolution coupling mechanism. The irradiator with the adjustable speed ratio rotation-revolution coupling mechanism aims to solve the problems of fixed or complicated adjustment methods for the rotation and revolution speed ratio of existing irradiators, which are difficult to accurately adapt to different irradiation process requirements, as well as the problem of easy slippage in friction transmission.

[0022] Please refer to Figures 1 to 6 The irradiator with an adjustable speed ratio rotation-revolution coupling mechanism includes a gear disk 1 and a mounting plate 4 disposed at the bottom of the gear disk 1. The mounting plate 4 is used to carry the object to be irradiated and moves with the gear disk 1. The irradiator with the adjustable speed ratio rotation-revolution coupling mechanism also includes a transmission mechanism 2 disposed at the rear side of the gear disk 1. The transmission mechanism 2 is a core component for power output and speed change, used to drive the gear disk 1 to rotate and adjust the speed. The transmission mechanism 2 includes a transmission box 201, which is fixedly installed at the rear bottom of the gear disk 1. A transmission gear is rotatably mounted on the front side of the top wall of the transmission box 201. 202. The transmission gear 202 meshes with the rear side of the gear disk 1. The rotation of the transmission gear 202 drives the gear disk 1 to rotate synchronously. The rear side of the top wall of the transmission box 201 is fixedly connected to the mounting shell 203. The drive motor 204 is fixedly installed inside the mounting shell 203. The output end of the drive motor 204 is fixedly connected to the friction wheel 1 205. The friction wheel 1 205 rotates with the drive motor 204 and serves as the driving wheel to input power. The bottom end of the central shaft of the transmission gear 202 is fixedly connected to the friction wheel 207. The friction wheel 207 serves as the driven wheel to receive power and drive the transmission gear 202 to rotate.

[0023] Please refer to Figure 4 and Figure 5 The transmission wheel 206 is disposed between the first friction wheel 205 and the second friction wheel 207. The outer wall of the transmission wheel 206 maintains frictional transmission contact with the outer walls of the first friction wheel 205 and the second friction wheel 207, respectively. The top and bottom ends of the transmission wheel 206 are rotatably connected to bearings 211. The left and right sides of the two bearings 211 are fixedly connected to connecting frames 210, which are used to support the transmission wheel 206 and the bearings 211. Mounting plates 209 are fixedly connected to the bottom of both the left and right sides of the outer wall of the transmission box 201. The mounting plates 209 are L-shaped. The vertical side of the mounting plate 209 is fixedly connected to the outer wall of the transmission box 201. The horizontal side of the mounting plate 209 is used to support and fix the electric push rod 208. There are two electric push rods 208, which are symmetrically distributed on the left and right sides of the transmission box 201. The electric push rod 208 is fixedly connected to the top wall of the mounting plate 209. The telescopic end of the electric push rod 208 is fixedly connected to the connecting frame 210. The electric push rod 208 is used to drive the connecting frame 210, thereby driving the transmission wheel 206 to move back and forth. Both friction wheel 1 205 and friction wheel 2 207 are conical structures, and the conical surface of friction wheel 1 205 is set opposite to the conical surface of friction wheel 2 207. This structure ensures that when the electric push rod 208 drives the transmission wheel 206 to move, the rotation radius of the contact point between the transmission wheel 206 and friction wheel 1 205 and friction wheel 2 207 changes, thereby achieving linear adjustment of the transmission ratio.

[0024] Please refer to Figure 6 The preferred structure of the extrusion mechanism 3 is described in detail below. The extrusion mechanism 3 also includes an adjusting rod 303, which is fixedly connected to the inner wall of the transmission box 201. The pressure head 301 is slidably connected to the outer wall of the adjusting rod 303. An adjusting nut 304 is threadedly connected to the outer wall of the adjusting rod 303. A moving ring 305 is also slidably connected to the outer wall of the adjusting rod 303. The moving ring 305 is located between the adjusting nut 304 and the pressure head 301. The extrusion mechanism 3 also includes a disc spring 306, which is sleeved on the outer wall of the adjusting rod 303. The two ends of the disc spring 306 abut against the side of the moving ring 305 facing the pressure head 301 and the side of the pressure head 301 facing the moving ring 305, respectively.

[0025] Working principle: When irradiation is required, the object to be irradiated is placed in the mounting plate 4, and the drive motor 204 is started. The drive motor 204 drives the friction wheel 205 to rotate. Since the outer wall of the friction wheel 205 is in frictional contact with the outer wall of the transmission wheel 206, the friction wheel 205 drives the transmission wheel 206 to rotate. The transmission wheel 206 further drives the friction wheel 207 to rotate. The friction wheel 207 drives the transmission gear 202 to rotate. The transmission gear 202 drives the gear disk 1 to rotate, thereby driving the object in the mounting plate 4 to rotate and revolve. When the rotational speed needs to be adjusted to adapt to different irradiation requirements, the electric push rod 208 is activated. The electric push rod 208 drives the connecting frame 210 to move the transmission wheel 206 vertically between friction wheel 1 205 and friction wheel 207. Since friction wheel 1 205 and friction wheel 207 have a conical structure, the movement of the transmission wheel 206 changes the rotation radius of the contact point between the transmission wheel 206 and friction wheel 1 205 and friction wheel 207, thereby changing the transmission ratio and realizing linear adjustment of the rotational speed of the gear disk 1. To ensure the stability of the friction drive and prevent slippage, the adjusting nut 304 is rotated. The adjusting nut 304 moves on the adjusting rod 303 and pushes the moving ring 305. The moving ring 305 compresses the disc spring 306. The disc spring 306 transmits pressure to the ball 302 through the pressure head 301. The ball 302 applies lateral compressive force to the first friction wheel 205 and the second friction wheel 207, so that the first friction wheel 205, the transmission wheel 206 and the second friction wheel 207 are kept in close contact. The rolling contact of the ball 302 reduces the frictional resistance while applying pressure.
