Description

Rotary slotting mechanism for plastic ampoules

technical field

The invention relates to a plastic ampoule rotary slotting mechanism, which belongs to the technical field of ampoule production equipment.

Background technique

The Blow/Fill/Seal technology (Blow/Fill/Seal) applied in the pharmaceutical industry is a kind of aseptic packaging technology. The machine completes the entire blow molding and filling of the container in a single process in an aseptic state. , Sealing process, the main working process of this equipment is: the spherical pellets enter the screw extruder from the hopper through the vacuum pump, and the molten pellets pass through the parison extrusion head to form single or multiple tube embryos. At this time, the main mold is closed. , the bottom is sealed, and the tube embryo is made into a container by compressed air or vacuum. After that, the mold moves to the filling station, the special mandrel goes deep into the preform, injects the liquid medicine, and the filling is completed. Then, the mandrel is withdrawn, and the head The molds are closed, the seal is formed by vacuum, the product is made, and the waste edge is cut to obtain the final product. The plastic ampoules produced by this equipment are all connected together, which is a separate plate-like structure, and each board is connected by 3-6 plastic ampoules. The product needs to be slit and torn when used. The slitting process needs to be carried out by operators, which has high labor intensity and low work efficiency, and it is difficult to guarantee subsequent continuous production.

Contents of the invention

According to the deficiencies in the prior art above, the technical problem to be solved by the present invention is: to provide a plastic ampoule rotary slotting mechanism, which has a compact structure, is convenient to use, and has high efficiency, and can meet the production speed requirements of batch products.

The plastic ampoule rotary slitting mechanism of the present invention comprises a pair of swing cylinders located at two ends, the swing cylinders are installed on the cylinder fixing plate, the two swing cylinders are connected to the swing shaft, and several cutter fixing seats are arranged on the swing shaft, Cutters are installed on the knife holder, and the cutters on the two swing shafts are symmetrically arranged, and a product placement component is correspondingly arranged below the cutters.

When in use, the plastic ampoule is placed in the product placement component, and the two swinging cylinders drive the two swinging shafts to rotate at the same time. The cutter follows the swinging shaft to rotate at a specific angle, and the two ends of the product are cut, and the middle is reserved, which is convenient for people to follow up on the cut product. Tear open and use.

Preferably, one end of the oscillating shaft is connected to the oscillating cylinder, and the other end is installed on the cylinder fixing plate at the corresponding end, so as to ensure the stability and accuracy of the movement of the cutter.

Preferably, a product pressure plate is provided between the two cylinder fixing plates, and the product pressure plate is correspondingly located above the product placement assembly, so as to prevent the plastic ampoule from being lifted up when the cutter is retracted.

Preferably, the swing cylinder is connected to the swing shaft through a coupling flange, and the connection is stable and firm.

Preferably, the product placement component is a product conveying slide rail component, including a device box for containing the product. The device box moves to a designated position through the slide rail, and the positioning is accurate, ensuring that the slotting position is accurate and easy to operate.

The beneficial effect that the present invention has compared with prior art is:

The ampoule rotary slitting mechanism has compact structure, simple operation and high efficiency, which meets the production speed requirements of batch products, and realizes partial slits of plastic ampoules, which is convenient for subsequent use, and the equipment cost is low, which is convenient for subsequent sterilization and labeling operations of products , which provides a guarantee for the continuous production of plastic ampoules.

Detailed ways

Embodiments of the present invention are further described below in conjunction with accompanying drawings:

As shown in Figures 1-4, the plastic ampoule rotary slit mechanism includes a pair of swing cylinders 1 located at both ends. The swing cylinder 1 is mounted on the cylinder fixing plate 2. Both swing cylinders 1 are connected to the swing shaft 4. 4 groups of cutter holders 5 are housed on the cutter holder 5, cutter 6 is installed on the cutter holder 5, the cutter 6 on the two swing shafts 4 is symmetrically arranged, and the cutter 6 below is correspondingly provided with product placement components.

One end of the swing shaft 4 is connected to the swing cylinder 1, and the other end is mounted on the cylinder fixing plate 2 at the corresponding end.

A product pressing plate 7 is arranged between the two cylinder fixing plates 2, and the product pressing plate 7 is correspondingly located above the product placement assembly.

The oscillating cylinder 1 is connected to the oscillating shaft 4 via a coupling flange 3 .

The product placement component is a product conveying slide rail assembly 9, which includes a device box for containing products, and the device box moves to a designated position through the slide rail.

Figure 5 is a plastic ampoule to be slitted, wherein the slit area 10 requires a cutter 6 to slit both ends of it, and the non-slit area 11 is a reserved part, which is convenient for hand tearing during subsequent use. The specific operation steps are as follows:

The first step: the plastic ampoule 8 is transported to the position to be cut through the product delivery slide rail assembly 9, and at this time, the two swing cylinders 1 are in the initial position, that is, the swing angle is 0°.

Step 2: supply air through the valve guide, the swing piston rod of the swing cylinder 1 rotates clockwise, and supply air through the valve guide, and the swing piston rod of the other swing cylinder 1 rotates counterclockwise, both of which rotate 90°. At this time, the two sets of swing cylinders 1 rotate clockwise and counterclockwise under the action of the piston rod of the swing cylinder, that is, they rotate inward at the same time, so that the cutter 6 rotates 90°, and the plastic ampoule 8 product is cut into the head and tail. Slit both ends. According to the design size, after the cutting knives 6 (2 sets of left and right sides) swing 90° respectively to complete the slit of the plastic ampoule 8, there will be no phenomenon of mutual interference.

Step 3: The plastic ampoule 8 completes the slotting operation, supplies air through the valve guide, and the two sets of swing cylinders 1 rotate in reverse 90°, and the plastic ampoule 8 that has been slotted is transported to the next station through the product delivery slide rail assembly 9 .
