Chocolate candy packaging machine design
First, the design topic Design a chocolate candy automatic packaging machine. The packaging object is a round table chocolate candy, and the packaging material is a golden aluminum foil paper with a thickness of 0.008 mm. The shape after packaging should be beautiful and straight, and the aluminum foil paper has no obvious damage, tear and wrinkles. Second, the basic analysis of chocolate candy packaging machine 1. The basic components of the chocolate candy packaging machine The chocolate candy packaging machine basically consists of a intermittent cutting paper feeding mechanism, an aluminum foil cone forming mechanism, a papermaking mechanism, and a chocolate candy feeding mechanism. 2. Determination of parameters Chocolate candy upper end diameter 17mm, lower end diameter 24mm, height 12mm Motor speed: 960 rev / min Packing rate: 120 capsules / min Appearance size: 800min*1000min (width*height) 3. Institutional selection (1) Paper feed action roller mechanism (2) Sugar tray transfer groove wheel mechanism, gear wheel train mechanism (3) Manipulator indexing sheave mechanism, gear wheel train mechanism, plane link mechanism, bevel gear mechanism (4) Paper-cutting action plane cam mechanism, plane link mechanism (5) Paper-making action cylindrical cam mechanism, plane link mechanism (6) top sugar action plane cam mechanism, plane link mechanism (7) Drip sugar action plane cam mechanism, plane link mechanism Third, exercise analysis The motor is decelerated to 24r/min through the sprocket to drive the drive shaft. The drive shaft passes through the bevel gear, and the sheave mechanism drives the sprocket to rotate, thus making the work go smoothly. The processing speed selected this time was 120 grains/min, which required the rotation speed of the robot and the sugar supply tray to be 20 r/min. Transmission ratio = 240/20 = 1.2 The selected pusher roller has a radius of 5mm. Secondly, the motion law of the putter should be selected. Because the motion is medium-high speed and light load, the push motion selects the sinusoidal acceleration motion law, and the return motion selects the fifth-order polynomial motion law. The requirements of the push rod: the cam rotates 90°, the push rod rises h, the cam continues to rotate through the 90° push rod to stop moving; the cam continues to rotate 60°, the push rod drops h, turns the rest angle, the push rod again Do not move. For a straight-acting roller pusher disc cam mechanism, the coordinates of the theoretical profile of the cam are Take the calculation interval as 5°, and substitute the above corresponding values ​​into equation (a) to calculate the coordinate values ​​of each point on the theoretical Contour line. It should be noted during the calculation that it should be taken during the push phase, taken during the far-off phase, and taken during the return phase, in the near-rest phase. Paper-cutting mechanism: the thickness of the paper is about 0.008 mm, taking h=0.1 mm; the paper-making mechanism h=15.00 mm; the top sugar mechanism h=30.00 mm; the sugar-drawing mechanism h=15.00 mm; Fourth, the parameters of chocolate candy packaging machine The radius of the primary circle is 50 mm. Get the corresponding results as follows: Paper cutting mechanism Maximum pressure angle of lift: 3.97°, maximum pressure angle of return stroke: 1.38°, minimum radius of curvature of theoretical profile: 46.80mm. 2. Top sugar institution Maximum pressure angle of lift: 7.60°, maximum pressure angle of return: 18.54°, minimum radius of curvature of theoretical profile: 24.78mm. 3. Sugar extraction mechanism Maximum pressure angle of lift: 13.54°, maximum pressure angle of return stroke: 35.69°, minimum radius of curvature of theoretical profile: 17.04mm. 4. Outer sheave z=6, the radius of the six-groove wheel is 45mm.
