Abstract

The utility model discloses a sieving machine, which comprises a stand, wherein the stand is provided with a feed box; the feed box is fixed on a feed box support frame; the two sides of the feed box support frame are provided with slider installation racks; sliders are arranged on the slider installation racks; two guide rails are symmetrically arranged upon the two sides of the stand; the sliders are in slip connection with the guide rails; the feed box is internally provided with a sieving plate; the sieving plate is distributed with a plurality of small holes for the qualified capsules to pass through; the bottom of the feed box is provided with a receiving box; both the bottom of the feed box and the upper part of the receiving box are open; and the feed box support frame is connected with an actuating unit for driving the support frame to do reciprocating motion on the guide rail. With the machine, the capsule with defects such as bur, slight deformation and the like which are invisible to the naked eye can be sieved, so the labor intensity is greatly reduced for workers, and the quality assurance is greatly improved compared with the manual sorting.

Description

A kind of screening machine

Technical field

The utility model belongs to the capsule screening plant, particularly a kind of screening machine that is used for rejecting the indiscoverable defective capsule of finished capsule product part naked eyes.

Background technology

Among the capsule manufacture process, can produce some defective substandard products capsules unavoidably, according to incompletely statistics, the defect kind of substandard products capsule is about 35 kinds, and these defectives must be rejected before dispatching from the factory, otherwise can produce customer complaint.The way of general capsule factory is: the cost lot of manpower and material resources, production capsule is carried out artificial separation by naked eyes, reject defective capsule, but in some defective capsules, some naked eyes is difficult to the little burr of resolution, defectives such as slight deformation, difficult discovery the when normal inspection, can flow to client inevitably, thereby produce customer complaint, influence our company's quality image.

Summary of the invention

The utility model provides a kind of screening machine that filters out defective capsules such as band burr, distortion at above-mentioned the deficiencies in the prior art, has realized the mechanization screening, has saved manpower and materials, has improved production efficiency.

The technical solution of the utility model is achieved in that

A kind of screening machine, comprise frame, on frame, be provided with charging box, charging box is fixed on the charging box bracing frame, be provided with the slide block installing rack in the both sides of charging box bracing frame, on the slide block installing rack, slide block is installed, in frame, be arranged with two guide rails above the both sides, described slide block and guide rail are slidingly connected, in charging box, be provided with sieve plate, on sieve plate, be distributed with the aperture that the qualified capsule of a plurality of confessions passes, be provided with the case that connects material in the charging box bottom, the bottom of charging box and the equal opening in top of case of connecting material, charging box bracing frame are connected with and drive himself reciprocating actuating unit on guide rail.

As preferably, be a bell on the described aperture, the bore of described bell reduces gradually along the landing direction of capsule.Bell plays the effect of guiding, slides down aperture to make things convenient for capsule to import.

As preferably, described actuating unit is a toggle, it includes disc crank, connecting rod and motor, the center of disc crank has axis hole, the output shaft of motor is connected with the axis hole close-fitting of disc crank, and an end of connecting rod and the limit portion of disc crank 21 are hinged, and the middle part of the other end and charging box bracing frame is hinged.

As preferably, motor is connected with frequency converter.Thereby can control the rotational frequency of motor output shaft, and then the round frequency of control charging box, satisfy the screening needs.

Adopted the advantage that the utlity model has of technique scheme to be:

The utility model is poured capsule to be screened in charging box, charging box is made back and forth movement on guide rail under the effect of toggle, qualified capsule can be slid down aperture and drop in the case that connects material, defective capsules such as burr capsule and slight deformation just can not be slid down sieve plate, be stuck in the aperture, regularly the defective capsule that can't pass sieve plate is absorbed with dust catcher, can be reached the purpose of rejecting this type of defective capsule; By this equipment, can remove effectively that many naked eyes can not see as defective capsules such as burr, slight deformation, greatly reduce working strength of workers, and quality assurance is greatly improved than artificial separation.

The specific embodiment

The specific embodiment of the present utility model is as follows:

Embodiment: a kind of screening machine, as Fig. 1, shown in Figure 5, comprise frame 1, on frame 1, be provided with charging box 2, charging box 2 is by being bolted on the charging box bracing frame 3, bilateral symmetry at charging box bracing frame 3 is provided with slide block installing rack 4, on each slide block installing rack 4, slide block 5 is installed, in frame 1, be arranged with two guide rails 6 above the both sides, described slide block 5 is slidingly connected with guide rail 6, in charging box 2, be provided with sieve plate 7, as shown in Figure 2, each side plate 22 bottom of forming charging box 2 internally extend supporting plate 23 to charging box, and sieve plate 7 is placed on the supporting plate 23, the size of sieve plate 7 is identical with charging box 2 interior size, so can not clash into the charging box 2 inboard sounds that produce when reciprocating.

As shown in Figure 3, Figure 4, be distributed with the circular aperture 9 that the qualified capsule of a plurality of confessions passes on the sieve plate 7, described aperture 9 upper ends are a bell 31, and the bore of described bell 31 reduces until identical with aperture bottom internal diameter gradually along the landing direction of capsule.Can process corresponding sieve plate according to the capsule of different model, each sieve plate hole diameter adds appropriate gap processing in strict accordance with the capsule external diameter, and above-mentioned gap is between 0.1～0.3mm.During screening different model capsule, change corresponding sieve plate and get final product.

Be provided with the case 8 that connects material in charging box 2 bottoms, the bottom of charging box 2 and the equal opening in top of case 8 of connecting material are so that after qualified capsule falls in the charging box 2 after the sieve plate screening, can drop in the case 8 that connects material.Charging box bracing frame 3 is connected with and drives himself reciprocating actuating unit on guide rail 6.Described actuating unit is a toggle, it includes disc crank 10, connecting rod 11 and motor 12, motor 12 is by being bolted on the frame 1, the center of disc crank 10 has axis hole, the output shaft 13 of motor 12 is connected with the axis hole close-fitting of disc crank 10, and an end of connecting rod 11 and the limit portion of disc crank 10 are hinged, and the middle part of the other end and charging box bracing frame 3 is hinged.

When work, in charging box 2, pour earlier capsule to be screened into, open motor 12, disc crank 10 is done circumferentially to rotate, and drivening rod 11 pulling charging box bracing frames 3 are reciprocating, and sieve plate screens capsule in the charging box 2; In order to control the round frequency of sieve plate, motor 12 is connected with frequency converter, by frequency converter is carried out program setting, can control the velocity of rotation of motor, and then the round frequency of control sieve plate screening.In the utility model, it is best at 70 times/minute that sieve plate comes and goes FREQUENCY CONTROL, otherwise qualified capsule just can not very smooth and easyly be slid down.
