Abstract
Description
Technical Field
[0001] This utility model relates to the field of material conveying technology, and in particular to a segmented bundle-type conveying mechanism. Background Technology
[0002] The electron beam irradiation material conveying device is an important component of the entire equipment. The beam conveying mechanism is used to transport irradiated materials through electron beam irradiation.
[0003] However, traditional transport mechanisms have significant shortcomings in electron beam scanning detection environments. First, when operating directly below the scanning window, the harsh high-energy electron beam environment exposes the equipment to strong radiation, significantly shortening its lifespan. Second, the continuous movement of the chain interferes with electron beam energy detection, affecting accuracy. This interference can lead to substantial errors, especially in applications requiring high-precision detection. Furthermore, most existing transport mechanisms are complex, making flexible adjustment in electron beam scanning environments difficult and unable to meet the needs of transporting materials of different specifications.
[0004] Therefore, there is an urgent need for a transmission mechanism that can adapt to the electron beam scanning environment, reduce electron beam interference, has a simple structure, and is easy to adjust, so as to improve the accuracy of electron beam scanning detection and the service life of the equipment. Utility Model Content
[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a segmented beam-down transmission mechanism to solve the problems of shortened equipment life and interference of continuous chain movement on electron beam energy detection in traditional transmission equipment when working in a high-energy electron beam environment.
[0006] To achieve the above and other related objectives, this utility model provides a segmented beam-down conveying mechanism, including an electric lifting platform and a rod-through conveyor. The rod-through conveyor is installed at the lifting end of the electric lifting platform. The rod-through conveyor includes a frame, two sets of sprocket conveying assemblies, and a power motor. Each set of sprocket conveying assemblies includes a drive shaft, a driven shaft, and a rod-through chain assembly. The two ends of the drive shaft are respectively provided with drive sprockets, and the two ends of the driven shaft are respectively provided with driven sprockets. The rod-through chain assembly is sleeved between the corresponding drive shaft and driven shaft, and the drive sprocket and driven sprocket are connected by a transmission through the rod-through chain assembly.
[0007] In one embodiment of the present invention, the rod conveyor further includes a rotatably configured transition shaft. The power motor is connected to the transition shaft via a first transmission assembly. The power motor is also connected to one of the drive shafts via a second transmission assembly. The transition shaft is connected to the other drive shaft via a third transmission assembly.
[0008] In one embodiment of the present invention, two drive shafts are rotatably disposed at both ends of the frame, two driven shafts are rotatably disposed at the middle position of the frame, and the power motor and the transition shaft are respectively installed at the lower ends of the frame.
[0009] In one embodiment of the present invention, the frame includes two side plates and a roller rotatably connected between the two side plates.
[0010] In one embodiment of the present invention, a gap adjustment device is provided between the two sets of sprocket conveying assemblies for adjusting the gap between them.
[0011] In one embodiment of the present invention, the frame is provided with a first sliding groove for the driven shaft to slide on both sides, and a second sliding groove for the drive shaft to slide on both sides. The gap adjustment device is respectively provided in the middle of both sides of the frame and is used to adjust the distance between the two driven shafts.
[0012] In one embodiment of this utility model, the gap adjustment device includes a bearing sliding seat, a slide rail, a fixed seat, and a bolt. The driven shaft passes through the first sliding groove and is rotatably connected to the bearing sliding seat. The frame has slide rails parallel to the first sliding groove on its upper and lower sides, respectively. The upper and lower ends of the bearing sliding seat are slidably engaged with the slide rails. The fixed seat is fixed to the outside of the first sliding groove. One end of the bolt is threaded to the fixed seat, and the other end of the bolt is connected to the bearing sliding seat. By rotating the bolt, the position of the bearing sliding seat relative to the fixed seat can be adjusted, thereby adjusting the horizontal position of the driven shaft and thus adjusting the distance between the two driven shafts.
[0013] In one embodiment of this utility model, the electric lifting platform is a scissor lift platform, which includes a base, a lifting platform, a scissor assembly, and a lifting motor. The scissor assembly is located between the base and the lifting platform, and the lifting motor is installed on the base to control the opening and closing angle of the scissor assembly.
[0014] In one embodiment of the present invention, the scissor lift assembly comprises at least two sets of scissor arms that are hinged together at their midpoints to form an X-shaped structure.

[0016] As described above, the segmented beam-down conveying mechanism of this utility model has the following beneficial effects:
[0017] 1. By adopting a segmented beam delivery mechanism design, the equipment avoids the direct irradiation area of the high-energy electron beam, effectively extending its service life. Traditional equipment operates directly below the scanning window and is exposed to the high-energy electron beam environment for extended periods. However, the segmented design of this invention keeps key components away from the high-energy radiation zone, significantly improving the equipment's durability.
[0018] 2. By incorporating a gap adjustment device, the gap between the two sets of sprocket conveyor assemblies can be adjusted according to actual needs, reducing the interference of continuous chain movement on electron beam energy detection and improving detection accuracy. In practical applications, precise gap adjustment allows the electron beam energy detection device to avoid the interference zone caused by chain movement, resulting in more stable and reliable detection results.
[0019] 3. By combining the height adjustment function of the electric lifting platform with the speed control of the power motor, precise control of the irradiation dose is achieved. By adjusting the distance between the material and the scanning window and the running speed of the conveyor belt, the irradiation dose can be precisely controlled according to the needs of different materials, meeting diverse irradiation treatment requirements.
[0020] 4. The modular, segmented conveyor belt design supports flexible expansion, ensuring smooth material transport while avoiding interference from high-energy electron beams on the detection device. This design gives the system excellent adaptability, allowing for adjustments and expansion based on actual production needs, thus improving the equipment's versatility and practical value.

The transition shaft 150 is connected to the drive shaft 121 that is close to it through the third transmission assembly 180.
[0031] The first transmission assembly 160 includes a first driving gear mounted on the output shaft of the power motor 130 and a first driven gear mounted on the transition shaft 150, with the first driving gear and the first driven gear being connected by a first chain. The second transmission assembly 170 includes a second driving gear mounted on the output shaft of the power motor 130 and a second driven gear mounted on the drive shaft 121 near the power motor 130, with the second driving gear and the second driven gear being connected by a second chain. The third transmission assembly 180 includes a third driving gear mounted on the transition shaft 150 and a third driven gear mounted on the drive shaft 121 near the transition shaft 150, with the third driving gear and the third driven gear being connected by a third chain.
[0032] A gap adjusting device 140 is provided between the two sets of sprocket conveying assemblies 120 to adjust the gap between them.

The gap adjusting device 140 is respectively located in the middle of the side plates 111 and is used to adjust the distance between the two driven shafts 122.
[0033] The clearance adjustment device 140 includes a bearing sliding seat 141, a slide rail 142, a fixed seat 143, and a bolt 144. The driven shaft 122 passes through the first sliding groove 113 and is rotatably connected to the bearing sliding seat 141. The frame 110 has slide rails 142 parallel to the first sliding groove 113 on its upper and lower sides. The upper and lower ends of the bearing sliding seat 141 are slidably engaged with the slide rails 142. The fixed seat 143 is fixed to the outside of the first sliding groove 113.

One side of each scissor arm is rotatably connected to an adjusting screw 231, and the other side is threadedly connected to the adjusting screw 231. The lifting motor 240 controls the rotation of the adjusting screw 231. Several buffer adjustment components are also provided between the base 210 and the lifting platform 220. These buffer adjustment components are hydraulic dampers used to reduce the impact force during the lifting platform 220's ascent or descent, protecting the equipment and materials.
[0036] In this embodiment, the segmented bundle conveying mechanism first adjusts the height of the rod conveyor via an electric lifting platform to match the height of the upstream and downstream equipment. Then, the power motor is started, driving the drive shafts of the two sets of sprocket conveying assemblies to rotate through the first, second, and third transmission components. The drive shafts drive the drive sprockets to rotate, which in turn drive the rod chain assemblies on them to rotate, thus realizing the material conveying. If the gap between the two sets of sprocket conveying assemblies needs to be adjusted, the distance between the two driven shafts can be adjusted through a gap adjustment device to adapt to the conveying requirements of materials of different specifications.
[0037] In summary, the segmented design of this invention keeps key components away from high-energy radiation areas, significantly improving equipment durability and effectively extending its service life. Furthermore, by incorporating a gap adjustment device, the gap between the two sets of sprocket conveyor assemblies can be adjusted according to actual needs, reducing interference from the continuous movement of the chain rod on electron beam energy detection and improving detection accuracy. Therefore, this invention effectively overcomes the various shortcomings of existing technologies and possesses high industrial applicability.
