[0034] The end of the lead screw 4 away from the sliding block 5 is fixedly connected with a rotating handle one 8, the rotating handle one 8 is convenient for the operator to hold and apply a rotating torque, so that the whole operation of adjusting the tension is simple and easy to operate, and the operator can complete it without the help of complex tools, which effectively improves the adjusting efficiency, the pulley 9 as a key component in the belt transmission assembly, the outside of the pulley 9 is coupled with a transmission belt 19, the rotation of the pulley 9 drives the transmission belt 19 to move, thereby realizing the transmission of power and ensuring the normal development of the related work such as feeding. The inside of the pulley 9 is provided with a replacement assembly for quick disassembly and assembly, which greatly improves the maintenance and replacement efficiency when the pulley 9 fails, reduces the downtime of the equipment, and ensures that the production can be resumed as soon as possible. The outside of the pulley 9 is provided with a driving assembly for feeding, which provides a power source for the whole feeding work, so that the materials can be conveyed according to the predetermined process, meeting the production and processing requirements.

[0035] Referring to Figure 1 , Figure 3 and Figure 4The replacement assembly comprises a fixed tooth 10, which plays a key role in positioning and fixing during the mounting and dismounting of the belt wheel 9. The cooperation of the fixed tooth 10 with the inside of the belt wheel 9 and the rotating column 6 can ensure that the belt wheel 9 is stably mounted on the rotating column 6 and accurately separated when dismounting is needed, ensuring the smooth operation of the mounting and dismounting. The outside of the fixed tooth 10 is slidingly connected to the inside of the belt wheel 9, so that the belt wheel 9 can be reliably connected to the rotating column 6 through the fixed tooth 10, ensuring that the belt wheel 9 will not be loose or have other abnormal conditions during normal operation, and ensuring the stability of the transmission. The rear end of the fixed tooth 10 is fixedly connected to a sliding column 11, which is a component connecting the fixed tooth 10 and the transmission rod 13, and transmits the movement of the transmission rod 13 to the fixed tooth 10. The end of the sliding column 11 away from the fixed tooth 10 is rotatably connected to the transmission rod 13, so that the fixed tooth 10 can slide in the corresponding track to realize the mounting and dismounting of the belt wheel 9. The outside of the sliding column 11 is slidingly connected to a fixed ring 12, which provides guidance and limiting action for the sliding of the sliding column 11, ensuring that the sliding column 11 can only move linearly in the predetermined direction, avoiding the occurrence of deviation and other conditions affecting the mounting and dismounting operation of the belt wheel 9.

[0036] The outer part of the transmission rod 13 is provided with a transmission assembly for driving, which realizes the effective connection between the manual operation of the operator and the movement of the transmission rod 13, so that the operator can conveniently and accurately control the disassembly and assembly of the belt pulley 9. The transmission assembly includes a sliding ring 14, which is fixedly connected with the transmission rod 13 and moves together with the transmission rod 13. The sliding ring 14 converts the rotary motion of the threaded column 17 into the linear motion of itself and the transmission rod 13 by cooperating with the threaded column 17 and other components. The threaded column 17 is slidably connected inside the sliding ring 14 and plays a key role in the intermediate conversion during the disassembly and assembly of the belt pulley 9. The outer part of the sliding ring 14 is fixedly connected to the outer part of the transmission rod 13, which ensures the synchronous movement between the two, making the power transmission more stable and reliable, and avoiding the problems of power interruption or low transmission efficiency. The threaded column 17, as a component for receiving the manual rotating torque of the operator, can drive the sliding ring 14 to move linearly, and then drive the entire disassembly and assembly process of the belt pulley 9. The operator can easily control this process by rotating the rotating handle 18 at the top of the threaded column 17. The inner side of the sliding ring 14 is fixedly connected with a plurality of sliding blocks 15, and the outer part of the threaded column 17 is provided with a sliding groove 16. The sliding blocks 15 cooperate with the sliding groove 16 on the threaded column 17, which not only guides the movement of the sliding ring 14 to ensure its linear movement along the axial direction of the threaded column 17, but also makes the connection between the sliding ring 14 and the threaded column 17 more stable, avoiding abnormal situations such as disconnection. The top of the threaded column 17 is fixedly connected with the rotating handle 18, which is convenient for the operator to manually apply a rotating torque. Its ergonomic design makes the operator operate more easily and comfortably, and the disassembly and assembly of the belt pulley 9 can be completed without much effort, improving the convenience of maintenance and replacement.

[0037] The sliding groove 16 cooperates with the sliding block 15 to provide a precise track for the sliding of the sliding ring 14, ensuring the accuracy and stability of the movement of the entire transmission assembly, so that the disassembly and assembly of the belt pulley 9 can be smoothly completed according to the predetermined process. The outer part of the plurality of sliding blocks 15 is slidably connected inside the sliding groove 16, which further ensures the standardization and stability of the movement of the sliding ring 14, so that the transmission rod 13 can drive the fixed teeth 10 to move accordingly under accurate driving, ensuring the efficiency and accuracy of the disassembly and assembly of the belt pulley 9. The outer part of the fixed teeth 10 is slidably connected inside the rotating column 6, and such connection makes the belt pulley 9 closely connected with the rotating column 6 through the fixed teeth 10. The belt pulley 9 can stably rotate with the rotating column 6 during normal operation to transmit power, and can smoothly separate when disassembled for easy replacement. The outer part of the fixed ring 12 is fixedly connected to the outer part of the rotating column 6, which ensures the position of the fixed ring 12 to be fixed, thereby providing stable sliding guide for the sliding column 11, so that the entire disassembly and assembly process of the belt pulley 9 can be orderly carried out on the basis of reliable structure.

[0038] The driving assembly comprises a transmission belt 19, which converts the rotation of the belt wheel 9 into its own circulation movement through the coupling connection with the belt wheel 9, thereby conveying the material to realize the feeding function. The transmission belt 19 is the key medium for power transmission in the whole feeding process, and factors such as its tension directly affect the efficiency and stability of feeding. The bottom end of the other two belt wheels 9 is fixedly connected with a motor 21, which serves as a power source to provide strong power support for the rotation of the belt wheel 9, so that the whole feeding assembly can stably operate, ensuring that the material can be continuously conveyed to meet the rhythm demand of production and processing. The motor 21 is fixedly connected to the top end of the frame 1, so that the motor 21 is stably installed and will not shake during operation to affect its power output and service life, and it is also convenient for line connection and other operations with other components to ensure the normal work of the electrical components of the whole equipment. The top end of the supporting plate 2 is fixedly connected with a spring pressure wheel 22, which can play a certain auxiliary tensioning role on the transmission belt 19 and can be self-adaptively adjusted according to the actual operation of the transmission belt 19 to avoid the phenomenon of excessive relaxation or excessive tension of the transmission belt 19, further optimizing the transmission performance of the transmission belt 19 and ensuring the smooth and efficient feeding work.

[0039] Working principle: when conveying a batch of materials, the motor 21 is started to drive the belt wheel 9 to rotate, thereby driving the transmission belt 19 to rotate, so that the whole feeding process runs. In the processing process, the tension may be abnormal. At this time, the rotating handle 8 can be manually rotated to drive the screw rod 4 to rotate in the fixed block 3, the fixed block 3 is rotated to drive the sliding block 5 to slide in the sliding groove 7, and the sliding groove 7 is slid to drive the belt wheel 9 to adjust the tension of the transmission belt 19, thereby avoiding the influence of abnormal tension on the transmission process and delaying the processing efficiency or affecting the processing quality.

[0040] When the belt wheel 9 fails, such as abnormal wear, abnormal noise or jamming, the rotating handle 18 can be rotated to drive the threaded column 17 to rotate in the rotating column 6, the threaded column 17 is rotated to drive the sliding ring 14 to rotate the transmission rod 13, thereby driving the transmission rod 13 to slide the sliding column 11 in the fixed ring 12, and finally the fixed teeth 10 are slid out of the inside of the belt wheel 9 to complete the disassembly of the belt wheel 9. At this time, a new belt wheel 9 can be replaced, and the new belt wheel 9 is slid outside the rotating column 6. After adjusting the position, the rotating handle 18 is reversely rotated to slide the fixed teeth 10 into the inside of the new belt wheel 9, thereby completing the quick installation of the new belt wheel 9. Through quick disassembly, the bearing can be immediately checked and replaced, greatly shortening the fault diagnosis and maintenance time and minimizing the impact on production progress, thereby improving the production efficiency as a whole.

[0041] It should be pointed out finally that: the above only for the preferred embodiments of the present application have, and not for limiting the present application, although the present application is described in detail with reference to the foregoing embodiments, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included in the scope of protection of the present application.
