Description

Design method and structure of ampoule neck wheel
Technical Field
The invention relates to the field of bottle making, in particular to a design method and a structure of an ampoule neck making wheel.
Background
In the industrial production of objects which need to be easily broken, for example, chocolate blocks need to be easily broken along a folding line and the end faces need to be kept flat, in the production line, when various tubular products are produced, the tubular products need to be cut by a specified length, and the process skill for cutting needs to be adopted to keep the end faces flat and smooth.
Particularly, in the production process of the ampoule bottle, the ampoule bottle is easy to break and the end face is flat. The specific reasons are as follows, the requirements of the YBB00332002-2015 low borosilicate glass ampoules and the YBB00332005-2-2015 borosilicate glass ampoules in 2015 national drug package standards are met: the ampoule is easy to break, and the broken section is flat (the section can not have sharp bulge, gap and crack whose length exceeds the shoulder). No matter the point mark or the color ring is easy to break, the mark or the color ring must be accurately scored or colored to the root of the ampoule curved neck, so that the ampoule is easy to break, the shoulder, the neck and the bulb at the ampoule curved neck part must be ensured to have good consistency in shape and size, and the shoulder can be accurately positioned. In order to have a flat cross-section after fracture (without sharp protrusions, notches and cracks with a length exceeding that of the shoulder), the wall thickness of the shoulder and the neck must be increased so that the shoulder and the neck can bear breaking force without breaking when being fractured (without sharp protrusions, notches and cracks with a length exceeding that of the shoulder occurring on the cross-section).
A horizontal ampoule machine is generally used for producing ampoules in China, and is popular due to the characteristics of simplicity and convenience in operation, high production efficiency, stable product quality, high cost performance and the like. When the ampoule bending neck is manufactured by the horizontal ampoule machine forming machine, the glass tube is supported by the roller in the horizontal direction, the glass tube is melted by fire heat vertically below the glass tube, and the neck manufacturing wheel uniformly presses dozens of ampoule bending necks down and simultaneously presses the ampoule bending neck for forming by a cam vertically above the glass tube. At the moment, dozens of ampoule bent necks are in a hot melting state (molten glass naturally droops), when the neck is vertically downwards pressed and formed in a small-size mode, redundant glass liquid is naturally accumulated downwards to the neck, so that the wall thicknesses of ampoule shoulders, necks and bubbles are increased (molten glass liquid resistance flows), and the molten glass liquid resistance flows and is unevenly stressed when the neck wheel is vertically upwards pressed and formed in a small-size mode under the influence of factors such as the outer diameter of a glass tube, the tolerance fluctuation of the wall thickness, the fluctuation of fire position, air disturbance and the like, so that the consistency of the shapes and the sizes of the ampoule shoulders, the necks and the bubbles and the increase deviation of the wall thickness are affected, the accuracy of shoulder positioning is further affected, when nicking or coloring rings cannot be manufactured at the roots of the ampoule bent necks, sharp bulges, gaps and cracks with the lengths exceeding the shoulders are easily generated on uneven sections when the ampoules are broken, and the deviation of breaking force is uncontrollable. Seriously influence ampoule breaking force standard (especially 5ml above ampoule), because ampoule is difficult to roll over and the section unevenness produces more glass bits on the one hand and seriously influences medicine safety in utilization, on the other hand causes nurse to operate the injury easily, so easy ampoule is difficult to roll over and the section unevenness seriously influences the security that ampoule used.
Therefore, the invention provides an ampoule neck bending and neck making wheel, which aims to solve the problems that an ampoule is not easy to break and the section is not flat in actual production and use and potential safety hazards.

establishing a second axis perpendicular to the first axis by means of the O point, the first axis and the second axis forming a first quadrant and a second quadrant such that OB is located in the first quadrant and OA is located in the second quadrant, taking the D point on the second axis such that LDOH is 4, which is the neck depth of the ampoule, and L isDON is equally divided, and corresponding coordinate points C are respectively obtained on a second axis1，C2，C3，……Cn-1，Ci＝iC1；
Determining the radius of the first arc as R, point (0, L)DO-R) as a center of a circle, with a point (0, C)n-1) Making the horizontal line intersect with the circular arc to form a line Bn-1Dot to obtain the length LBn-1Cn-1Passing point (0, L) EDO) And coordinate point (L)Bn-1Cn-1，Cn-1) Making a first arc line;
the radius of the second arc is determined to be 1.618 x η x R, in combination with coordinate point (0, L)DO) And coordinate point (-1.618 × η × L)Bn-1Cn-1，Cn-1) Making a second arc line;
sequentially obtaining coordinate points B in the first quadranti＝[LBn-1Cn-1+(n-1-i)S，iC1]Point B to coordinate point (L)Bn-1Cn-1，Cn-1) The coordinate points are connected in sequence to form a first curve;
sequentially obtaining coordinate points A in the second quadranti＝[-1.618×η×[LBn-1Cn-1+(n-1-i)S]，iC1]，
Point A to coordinate point (-1.618 × η × L)Bn-1Cn-1，Cn-1) Coordinates of (2) betweenThe points are connected in sequence to obtain a second curve.
Above, LABIs the length between AB, LAOIs the length between AO, LBOIs the length between BOs, eta is viscosity correction coefficient, eta is 0.7095, n is positive integer, i is more than or equal to 1 and less than or equal to n-1, C1＝LDO/n，S＝(LDO-LBn-1Cn-1)/(n-1)。
