  • Externally-mounted Motorized PulleyExternally-mounted Motorized Pulley

      For externally-mounted motorized pulley, electric motor is removed out of the ordinary motorized pulley. And the pulley still with a retarding mechanism is often referred as a retarding drum. The motor is externally connected with the retarding drum to constitute an externally-mounted motorized pulley.
      The externally-mounted motorized pulley is a kind of conveyor driving device between the traditional open-type drive mode from motor to reducer then to the drive pulley and the common motorized pulley driving mode. Because of the external motor, it enjoys good heat dissipation performance and easy repair and replacement. It takes about one-third less than the open-type drive in occupying space and manufacturing materials.
      The externally-mounted motorized pulley is the product of the current industrial requirements. From the logic diagram, the main components are still connected in series, and at least one more drive shaft is needed. From the reliability, there is no increase in reliability. However, due to its good heat dissipation in the motor, convenience installation, maintenance and inspection of the motor, as well as its superiority in occupying space and manufacturing materials to the old open-type drive, the externally-mounted motorized pulley is usually used in high-power externally-mounted motorized pulley, and it is a suitable driving device in some high-power applications.

              Shenyang Juli Mechanical Design Co., Ltd. adopts advanced technology, such as non-equal-pitch helix axis blades and the gradual transition from the beginning to the end of the blade. The blade is made from high wear-resistant, corrosion-resistant materials, with features of smooth feeding, high strength, good anti-abrasion, etc. The thickness of the spiral blade can be increased to enhance blade strength and extend the service life. Adding knockout angle steel in the center of the outlet makes the material flowing more fluid and improves the stress state of the blade to prevent the blade from open welding or bending on the tip, to avoid the opposite blade’s breakage due to fatigue failure and make sure the coal column level is basically uniform decline without blocking.
              Shenyang Juli Mechanical Design Co., Ltd. has the supply of 6m coke oven supporting spiral feeder, 7m coke oven supporting spiral feeder and 7.63 m coke oven supporting spiral feeder, as well as offering customized services.

            • Intelligent system for detecting tooth decay using piezo vibration and 100 accuracyIntelligent system for detecting tooth decay...

                Always Special attention has been paid to the accurate diagnosis of dental caries in dentistry.
                To detect dental caries At the occlusal levels via The perfect mirror And at interdental levels The use of radiographs of Bytewing .
                addition to the cost of Preparing radiographs , It expands the patient to x-rays, which itself has multiple complications.
                Different radiographic systems are one of the main diagnostic tools in dentistry.
                As a result of an increase in the number of illnesses resulting from laser imaging that is the result of this radiation , And the increase in radiation damage to humans.
                The best way to detect with 100% accuracy And without zero percentages, To improve the quality of decay detection and Renounce all the problems listed , Decided to design got this device.

                The complications and problems of radiographic systems:

                **Diseases of the skin and cancer caused by x-rays for dentists and patients
                **Physical complications for pregnant women in embryos
                **High cost in the preparation and maintenance of radiographic equipment
                **Lack of accurate diagnosis of decay (detection of up to 60%) Or the separation of amalgam from the tooth (detecting up to 25%) in the restorative tooth By radiography devices
                **Detection of decay (detection 0%) or separation of amalgam substance from the tooth in restorative tooth by oral sensors

                ** Specific objectives of the project

                1. Record the waves from healthy teeth
                2. Record the waves from the teeth with 0.5 mm cavities
                3. Record waves from teeth with 1 mm cavities
                4. Record waves from 1.5 mm cavities
                5. Record waves from teeth with 2 mm cavities
                6. Compare the two primitive groups together
                7. Record radiographs of sample teeth
                8. Review the synchronization of radiographic images with the designed model

                ** Applied Schemes

                • Possibility of examining tooth decay in pregnant women and the elderly
                • Facilitating the examination of dental caries and studying the separation of amalgam from the tooth in restored teeth ,dont need to go to radiographic centers And exposure to laser radiation (Notably, the most advanced X-ray devices are not able to do it)
                • High accuracy of detection than radiography devices up to 100% accuracy of detection
                • Cheaper prices, so all dentists will be able to buy this device
                • Because of its low cost of service, it does not cost much, and it's a welfare for patients
                • Avoiding time to go to the radiography clinic and returning to the dentist's office.

                Teeth are randomly divided into 5 groups of 20 teeth. In groups 1-4, cavities at 0.5, 1, 1.5 and 2 depths in the teeth will be created as a decay model. In the fifth group, no cavity will be created. By contacting the ultrasonic probe with the teeth, the waves received by the detector will be recorded.

                The next steps are as follows:
                1- 3D modeling of the device in Solidworkes 2016 Software
                2. Load dynamic forces and dynamic analysis with MC Adams software
                3. The loading forces of motion and vibration analysis software ANSYS 17.1
                4. Vibration testing of teeth with ME Scope software for comparison with modeling analysis
                Next step The teeth are parallel radiographs and the result will be compared with the model. Statistical analysis of data By one-agent variance analysis and The appropriate follow-up is used to compare two-dimensional groups in groups.

                At this point, our data will be ready for the device library And the device becomes the program.

                The cost of the Intelligent system for detecting tooth decay using piezo vibration and 100% accuracy:

                **Making the original model Body with a beautiful look:2500$
                **Modal and harmonic vibration testing on 200 human tooth samples ( We will receive from the bank of dentistry of medicin university):19000$
                **Build a humanoid robot to move and sit on a dental unit To view system performance :4000$
