PVC pipe joint bale splitter constructs

Technical Field

The utility model relates to the technical field of mechanical glue cutting equipment, in particular to a glue cutting mechanism for a PVC pipe joint.

Background

At present, when a PVC pipe joint is produced by using a mould for batch injection molding, in order to ensure that injection molding materials completely fill a cavity in the injection mould, the injection molding materials injected by a glue inlet on the injection mould are slightly more than the actual volume of the cavity, and a product piece after injection molding and redundant plastics (simply called waste materials) in a plastic flow channel are connected together, so that the product and the waste materials must be cut off by means of a manual cooperation cutter.

At least two rows of cavities are arranged regularly on the existing die for producing the PVC pipe joint, waste is usually arranged between the pipe joints formed by injection molding in two adjacent rows of cavities, and the waste connects the two adjacent rows of pipe joints together, so that the waste between the two adjacent rows of pipe joints is required to be cut off, the pipe joints can be independently arranged singly, and further processing or packaging and selling are facilitated.

However, in the prior art, the waste is cut off by manually matching with the cutter, so that the working efficiency is low, and the labor cost is high.

Disclosure of Invention

The utility model aims to provide a PVC pipe joint rubber cutting mechanism, so that waste materials can be automatically cut off, and the working efficiency is improved.

In order to achieve the above purpose, the utility model adopts the following technical scheme: PVC coupling bale splitter constructs, including at least a set of cutting unit, the cutting unit includes the frame, sliding fit has the slide in the frame, fixedly connected with cutter on the slide, be equipped with in the frame and be used for driving the reciprocal gliding driving piece of cutter, the cutter can slide to between two adjacent calandria joints and excision is carried out the waste material.

The principle and the advantages of the scheme are as follows: during practical application, the cutting unit in the scheme is arranged on one side of the die, the cutter faces to the position between two adjacent calandria joints, the cutter on the sliding plate can be pushed to be inserted between the two calandria joints through the driving piece and slide along the plurality of pipe joints, and the cutting edges on two sides of the cutter cut off waste materials between the two calandria joints in the sliding process, so that the waste materials are separated from the pipe joints, the pipe joints are mutually independent, and the next procedure is conveniently entered.

The waste material that connects between can realizing automatic excision coupling in this scheme no longer need manual cutting, the effectual work efficiency that has improved has saved artifical labour cost.

Preferably, as a modification, a mounting block is connected to a side of the slide plate facing the mold, and the cutter is fixed to the mounting block.

Preferably, as an improvement, the cutter comprises two blades, and the two blades are respectively positioned at two sides of the mounting block and connected with the mounting block.

So set up, the cutter comprises two blades, compares to set up the cutter into an holistic blade, and two blades can cut off the waste material on two rows of pipe joints respectively in this scheme, and the cutting edge width of single blade can be reduced in the setting of two blades, and is more sharp, and the waste material that cuts off that can relax, and single blade width is narrower, is convenient for stretch to between coupling and the waste material, makes separation effect better between waste material and the coupling.

Preferably, as a modification, the cutting units are provided with two groups, and the two groups of cutting units are respectively positioned at two sides of the die.

So set up, two sets of cutting unit are located the both sides of mould respectively in this scheme, can reduce single slide gliding travel distance like this to the travel requirement to the driving piece is little, more practical.

And this scheme can avoid having set up a set of cutting unit because of only, and cause the stroke distance of required driving piece big, lead to the volume also great to avoid leading to the whole area occupied of cutting unit big, waste space.

Preferably, as a modification, a guide rail is connected between the two frames, and the sliding plates are in sliding fit with the guide rail.

So set up, the setting of guide rail can play the effect of direction to the slip of slide, makes the sliding motion of slide more steady.

Preferably, as a modification, two guide rails are provided, and the two guide rails are respectively positioned at two ends of the die.

So set up, the setting of two guide rails in this scheme can further improve the guide effect to the slide, makes the slide more steady in the slip in-process.

Preferably, as an improvement, a limiting block is arranged on the guide rail, and the limiting block is positioned on the symmetry center line of the die.

The setting of stopper can play the effect of restriction slide sliding distance in this scheme, prevents that cutter on two slides from producing the collision and damaging.
