Abstract

The invention discloses a butyl rubber plug static electricity removal and vibration screening machine, which relates to the field of screening machines. A static eliminator is arranged above a vibrating screen to eliminate the static electricity on products, so that foreign substances absorbed on the products can loose, and the foreign substances and the products can be separated through the vibrating screen; a natural vibration frequency is obtained through a formula; when the frequency is equal to the rotation frequency of a vibrating motor, the best screening effect can be achieved; a 1-3 cm gap exists between an obliquely arranged screen mesh and a striker plate, so that only a small quantity of products can pass through the gap each time; and under the actions of gravity and vibration, the products move from the high end of the screen mesh to the low end, thereby improving the screening efficiency. The purpose for removing the foreign substances on the surfaces of the products is realized under the actions of static electricity removal and vibration, and the butyl rubber plug static electricity removal and vibration screening machine has simple operation and satisfied effect proved by trials.

Description

Butyl rubber plug static electricity removal and vibration screening machine

Technical field

The present invention relates to screening machine field, particularly a kind of for remove the butyl rubber plug static electricity removal and vibration screening machine of butyl rubber plug product surface absorption foreign matter in the butyl rubber plug production process.

Background technology

Medicinal butyl rubber stopper is the seal for drug encapsulation, because it directly contacts with medicine, therefore require high to the product cleanliness factor, because butyl rubber Electrostatic Absorption ability is strong, and its production process is more more complicated, therefore its product surface often adsorbs the foreign matters such as the hair that exists in buffings that the product flash trimming is arranged, environment, fiber in process of production, also is difficult to remove fully by cleaning, and often has the pharmaceutical factory to be subject to complaint about plug foreign matter in product.On market, butyl rubber plug manufacturer also uses the screening machine, want by effect of vibration by product spring repeatedly on the steel mesh track, the little foreign material machinery that invests between product surface or holes of products seam is broken away from, but verify through a large amount of the use, can only remove the larger foreign matter in butyl rubber plug surface, and less, the thinner foreign matter of part is removed difficulty, and the effect of screening is not ideal, and this light, thin, little foreign matter existence is the maximum hidden danger that use in the pharmaceutical factory all the time.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of butyl rubber plug static electricity removal and vibration screening machine, can effectively remove the foreign matter of butyl rubber plug product surface absorption.

For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of butyl rubber plug static electricity removal and vibration screening machine, vibratory sieve are arranged on frame, are provided with Xelminator above vibratory sieve;

In described vibratory sieve, vibrate the pond and tilt to be arranged on frame by vibrating spring, screen cloth is arranged on and vibrates in the pond, vibration pond low side is provided with the refuse collecting outlet, the screen cloth low side is provided with discharging opening, and screen cloth high-end top is provided with striker plate, and the vibration pond has vibrating motor;

Xelminator is connected with pressure-air with power supply, and high voltage direct current imports the ion pin in Xelminator 5, in its point discharge, part is charged ion from the pressure-air ionization that Xelminator 5 nozzles blow out.

The eigentone of described vibratory sieve is obtained by following formula approximate calculation:

$v=\frac{1}{2\mathrm{\π}}\sqrt{\frac{\mathrm{nk}}{m}}.$

The 1-3cm gap is arranged between described striker plate and screen cloth.

A kind of butyl rubber plug static electricity removal and vibration screening machine provided by the invention by Xelminator is set, is eliminated the static on product above vibratory sieve, make the foreign matter that adsorbs on product loosening, then make foreign matter and separation of products by vibratory sieve; By the eigentone that formula obtains, when its frequency equates with the rotational frequency of vibrating motor, can reach best screening effect, in formula, v is the eigentone of machine; N is the number of this mechanism's medi-spring; K is the coefficient of elasticity of each spring; M is the quality of oscillating component in mechanism.The 1-3cm gap is arranged between the screen cloth that is obliquely installed and striker plate, can make and only have a small amount of product to pass through from the gap at every turn, under the effect of gravity and vibration, product is high-end to low end motion from screen cloth, thereby reaches screening effect.

The present invention is by the purpose that realize to remove the product surface foreign matter with effect of vibration that destatics to product, and easy and simple to handle, through on probation, and good results.

Description of drawings

Fig. 1 is that the master of structure of the present invention looks schematic diagram;

Fig. 2 is the schematic top plan view of structure of the present invention;

Fig. 3 is the operation principle schematic diagram of Xelminator in the present invention.

The specific embodiment

In Fig. 1, Fig. 2, frame 1 is the carrier of complete equipment, and frame has six columns, and wherein four tops connect vibrating spring 2, and another two upper ends are Xelminator 5 fixedly, and these parts do not move at work in complete equipment.During work, vibrating motor 7 rotates, thereby makes the parts of vibrating spring 2 or more, and the vibratory sieve of involving vibrations pond 3, striker plate 4, screen cloth 6, vibrating motor 7, refuse collecting outlet 8 and discharging opening 9 compositions vibrates together.Screen cloth 6 is arranged in vibration pond 3, and vibration pond 3 tilts to be arranged on vibrating spring 2, and an end at discharging opening 9 places is slightly low, and product can bound forward from infeed end in vibration processes, until discharging opening 9.Vibrations pond housing 3, striker plate 4 and screen cloth 6 are limited in the high-end feed zone of screen cloth 6 with product to be sieved, and between striker plate 4 and screen cloth 6,1 to 3cm gap are arranged, and pass through for product to be sieved.In the process that bounds forward, part due to Electrostatic Absorption with product adhesion chip more closely, in the time of below by Xelminator 5, static will be neutralized.Can leave product with the untight chip of product adhesion in jump process and fall into vibration pond 3 below screen cloth 6, collect post processings from the refuse collecting outlet 8 of vibration pond 3 low sides at last.

Vibratory sieve and spring 2 consist of a spring oscillator, and its eigentone is arranged, and when its frequency equated with the rotational frequency of vibrating motor 7, this equipment can reach best effect.In design, the equipment eigentone can be by following formula approximate calculation:

$v=\frac{1}{2\mathrm{\π}}\sqrt{\frac{\mathrm{nk}}{m}}$

Wherein: v is the eigentone of machine; N is the number of this mechanism's medi-spring; K is the coefficient of elasticity of each spring; M is the quality of oscillating component in mechanism.

in Fig. 3, Xelminator 5 need of work power supply and pressure-airs, working power is 220 volt of 50 hz AC electricity, the HVDC electric generator changes it into high voltage direct current, high voltage direct current imports the ion pin in Xelminator 5, in its point discharge, part is charged ion from the pressure-air ionization that Xelminator 5 nozzles blow out, then the air with positive and negative charge contacts with product, with the ion of product tape like charges due to the Coulomb repulsion meeting away from product, with the ion of product tape xenogenesis electric charge due to the motion of macroscopical air-flow and electrostatic attraction and near product, last and electrically charged neutralization of product.
