Description

Technical Field

[0001] This utility model belongs to the technical field of medical solid waste disposal equipment, specifically relating to a power transmission mechanism for medical solid waste disposal equipment. Background Technology

[0002] Medical waste is a special type of hazardous waste that poses a great threat to the environment and human health. Unlike household waste, medical waste contains a large number of bacteria, viruses and chemical agents, and has extremely high infectivity, biotoxicity and corrosiveness. If untreated or incompletely treated medical waste is dumped at will, it will easily cause pollution to water bodies, soil and air, and cause direct or indirect harm to human health.

[0003] Currently, medical waste disposal equipment on the market typically uses a motor to drive a main shaft via a belt to grind and heat the medical waste. The motor is usually a high-power variable frequency motor, which typically weighs as much as 600 to 700 kilograms. The traditional belt tensioning method mainly involves adjusting the distance between the motor and the main shaft to tighten the belt. This method requires the motor to be hoisted for movement, which is especially inconvenient when replacing the belt at the customer's site (usually a hospital) due to the lack of hoisting equipment. This makes equipment maintenance and operation very inconvenient and urgently needs improvement. Utility Model Content

[0017] The present invention will be further described below through specific embodiments.

[0018] Reference Figures 1 to 5 As shown, a power transmission mechanism for medical solid waste disposal equipment includes a drive motor 1, a drive pulley 2 disposed at the output end of the drive motor 1, a driven pulley 3 disposed opposite to the drive pulley 2, a transmission shaft 4 connected to the driven pulley 3, a transmission belt assembly disposed between the drive pulley 2 and the driven pulley 3, an adjustment mechanism 6 for adjusting the tension of the transmission belt assembly, and a mounting base 7 for mounting the drive motor 1.

[0019] The drive motor 1 is mounted on the mounting base 7 and includes a connecting edge 11 connected to the mounting base 7 at the output end and an output shaft 12 connected to the drive pulley 2 at the output end. The mounting base 7 is provided with a through hole 71 for the output shaft 12 to pass through. Specifically, the connecting edge 11 is fixed to the mounting base 7 by a connector 8. The connector 8 includes a plurality of first connecting holes 81 circumferentially distributed on the mounting base 7, a plurality of second connecting holes 82 circumferentially distributed on the connecting edge 11 opposite to the plurality of first connecting holes 81, and a plurality of connecting bolts 83 that pass through the plurality of second connecting holes 82 and are threadedly connected to the opposite first connecting holes 81.

[0020] The transmission belt assembly includes multiple transmission belts 5 arranged at intervals along the vertical direction, with each transmission belt 5 tensioned between a driving pulley 2 and a driven pulley 3. The driving pulley 2 has multiple first positioning grooves 21 arranged vertically on its outer periphery, and the driven pulley 3 has multiple second positioning grooves 31 arranged vertically on its outer periphery. The multiple first positioning grooves 21 and the multiple second positioning grooves 31 are opposite each other. The multiple transmission belts 5 are respectively tensioned in the multiple first positioning grooves 21 and the opposite second positioning grooves 31. By defining the structural composition of the transmission belt assembly, the transmission between the driving pulley 2 and the driven pulley 3 is achieved through the cooperation of multiple transmission belts 5. This results in a larger contact area between the transmission belt assembly and the driving pulley 2 or the driven pulley 3, more uniform load distribution, and greater transmission capacity, thereby increasing the stability and reliability of the transmission, improving transmission efficiency, and reducing energy loss.

[0021] The adjustment mechanism 6 includes an adjustment frame 61, multiple adjustment components 62 disposed on the adjustment frame 61 and opposite to multiple transmission belts 5, and a limiting component 63 disposed on the adjustment frame 61 to limit the multiple adjustment components 62. Specifically, the adjustment component 62 includes an adjustment seat 64 that can move back and forth relative to the adjustment frame 61, a connecting rod 65 that is movably disposed on the adjustment frame 61 and connected at one end to the adjustment seat 64, an adjustment wheel 66 disposed on the adjustment seat 64 and abutting against the relative transmission belts 5, an adjustment compression spring 67 sleeved on the connecting rod 65 and connected between the adjustment seat 64 and the adjustment frame 61, and a guide member 68 disposed between the adjustment seat 64 and the adjustment frame 61.

[0022] The adjusting seat 64 includes an adjusting seat body 641, two mounting plates 642 arranged opposite to each other on the outside of the adjusting seat body 641 and opposite to the relative transmission belt 5, and a mounting rod 643 rotatably arranged between the two mounting plates 642, wherein the adjusting wheel 66 is movably arranged on the mounting rod 643 and abuts against the relative transmission belt 5.

[0023] The guide member 68 includes two guide rods 681 disposed opposite to each other on the adjusting seat 64 and two guide bearings 682 disposed at intervals on the adjusting frame 61 for the opposite guide rods 681 to pass through. The first end of the guide rod 681 is connected to the adjusting seat 64, and the second end extends along the direction close to the adjusting frame 61 and passes through the opposite guide bearing 682. By defining the structural composition of the guide member 68, it is ensured that the adjusting spring 67 maintains the correct direction of movement during operation, preventing deviation or tilting, thereby ensuring the stability and reliability of the tension adjustment of the relative transmission belt 5 by the adjusting wheel 66.

[0024] The limiting component 63 includes a limiting frame 631 disposed on the side of the adjusting frame 61 away from the adjusting component 62 and a plurality of limiting screws 632 arranged at intervals in the vertical direction. The limiting frame 631 is provided with limiting screw holes 633 that mate with the limiting screws 632. The first end of the connecting rod 65 is connected to the adjusting seat 64, and the second end passes through the adjusting frame 61 and abuts against the corresponding limiting screw 632. Specifically, the limiting frame 631 includes two horizontal rods 634 disposed vertically opposite each other on the side of the adjusting frame 61 away from the adjusting component 62, and a connection between the two horizontal rods 634. A vertical rod 635 is provided, and a limiting screw hole 633 is provided on the vertical rod 635, so that a certain distance is formed between the limiting screw 632 and the adjusting frame 61, which facilitates the adjustment of the position of the limiting screw 632 according to the tension requirements of the transmission belt 5; furthermore, the limiting frame 631 and the adjusting frame 61 are integrally formed; specifically limiting the setting of the limiting component 63, the limiting screw 632 is provided at the rear end of the connecting rod 65. During adjustment, the position of the limiting screw 632 can be adjusted to fine-tune the compression distance of the adjusting spring 67, so that the transmission belt 5 can obtain more precise tension.

[0025] During operation, different adjusting springs 67 with different wire diameters and pitches can be used for different positions of the transmission belts 5 to obtain different tensions. The two sets of adjusting mechanisms 6 on the left and right can simultaneously adjust the tension of the same transmission belt 5. Finally, by fine-tuning the position of the limit screw 632, multiple transmission belts 5 can obtain the same tension. When maintaining the belts, the limit screw 632 is first fine-tuned according to the different wear conditions of the transmission belts 5. If the fine-tuning cannot obtain the corresponding tension, the adjusting spring 67 is replaced. The operation is simple and convenient.

[0026] This application specifically defines the structural composition of the transmission belt assembly, which uses multiple transmission belts 5 to achieve transmission between the driving pulley 2 and the driven pulley 3. This results in a larger contact area between the transmission belt assembly and the driving pulley 2 or driven pulley 3, more uniform load distribution, and greater transmission capacity, thereby increasing the stability and reliability of the transmission. Furthermore, it defines the structural composition of the adjustment mechanism 6, providing separate adjustment components 62 for different transmission belts 5 to adjust the tension of the relative transmission belt 5 individually. This is because even belts from the same batch may have different incoming lengths; therefore, the separately provided adjustment components 62 can... This ensures that multiple drive belts 5 achieve the same tension. During equipment maintenance, only the structure of the adjusting component 62 needs to be adjusted, different adjusting springs 67 need to be replaced, or the drive belts 5 need to be replaced. No large hoisting equipment is required, making the operation simple and convenient. The adjusting component 62 is equipped with adjusting springs 67, and different tensioning effects can be obtained by replacing adjusting springs 67 with different clamping forces. Specifically, the structure of the limiting component 63 is limited, and a limiting screw 632 is set at the rear end of the connecting rod 65 to fine-tune the compression distance of the adjusting springs 67, so that the drive belts 5 can achieve more precise tension.

[0027] The above description is merely a preferred embodiment of the present utility model, and therefore cannot be used to limit the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the patent application and the contents of the specification of the present utility model should still fall within the scope of the patent of the present utility model.
