Description

Method and apparatus for supplying rubber material to injection molding machine

Technical Field

The present invention relates to polymer processing technology, and more particularly, to a method and apparatus for supplying rubber material to an injection molding machine.

Background

In the rubber injection molding technology, compared with general high molecular monomer, natural or artificial rubber raw material has a larger specific gravity and an increased weight, and is not suitable for feeding the rubber raw material into an extrusion cylinder of an injection machine by using a feeding groove such as a hopper as a container.

However, in the feeding process, because the rubber material belt has a heavy weight, when the rubber material belt is rolled and pulled, the rubber material belt is often broken due to improper pulling or excessive load, which causes the interruption of the supply of the raw material, if the rubber material belt is not found and processed in time, the manufacturing quality and efficiency will be poor, therefore, in order to reduce the occurrence rate of the belt breakage, in the new patent antecedents of TW083206726 and TW089209854, a proper guiding device is provided around the material inlet of the extruding cylinder to guide and assist the rubber material belt, so as to make the movement of the rubber material belt entering the extruding cylinder smooth, and avoid the occurrence of the breakage caused by pulling due to entanglement of the material belt.

It is obvious that the above patent documents can make the movement of the material belt near the feeding port obtain proper guidance, but lack the corresponding technology for other parts of the material belt to be rolled, so that the material belt still needs to be added with proper anti-sticking agent when being placed in a roll to avoid the sticking of the unvulcanized rubber material belt, and the added anti-sticking agent can not be removed before the material belt enters the extruding cylinder, which affects the quality of the finished product.

Disclosure of Invention

The main object of the present invention is to provide a method for supplying rubber material to an injection molding machine, which can properly disperse and support the weight of a rubber material strip, thereby reducing the occurrence of material breakage of the rubber material strip.

In order to achieve the above object, the present invention provides a method for supplying rubber material to an injection molding machine, wherein a rubber material strip is suspended in the air in a zigzag manner before being fed to a feeding port of an injection extrusion cylinder of the injection molding machine, and the downward meandering portions of the rubber material strip are supported respectively, so as to disperse the overall weight of the rubber material strip.

The rubber material belt is hung on a first hanging piece before being fed into the injection extrusion cylinder, and the first hanging piece supports and disperses the weight of the rubber material belt.

Furthermore, the method for dispersing the weight of the rubber raw material belt provided by the invention can lead the rubber raw material belt to move along with the displacement of the rubber injection machine, thereby realizing the configuration of arranging a plurality of mold workstations by a single or a small number of injection machines, greatly improving the manufacturing efficiency of the rubber injection molding technology and reducing the cost of equipment.

To this end, the present invention provides a method for supplying rubber material to an injection molding machine, which allows the injection molding barrel to reciprocate between a start position and an end position, and allows the rubber material belt and the injection molding barrel to synchronously move.

Furthermore, in order to achieve the effect of automatic and continuous feeding, in the method for supplying rubber material to the injection molding machine provided by the invention, the material of the rubber material strip is prepared at a supplement position, and the supplement position is adjacent to the initial position or the final position.

In addition, in order to facilitate the implementation of the method, the invention further provides a device for supplying rubber raw material to the injection molding machine, which comprises a hanging piece, a body, a plurality of hanging bodies which are separated from each other and are suspended in the air, and a plurality of accommodating spaces which are respectively arranged on the body and are respectively arranged between the adjacent hanging bodies, so that the strip-shaped rubber raw material strip can be hung on each hanging body in a winding way and penetrates through the corresponding accommodating space to be hung on the hanging piece.

Wherein, in order to suspend the rubber material belt in the air, a carrying piece is further used for arranging the hanging piece, so that the hanging piece is suspended in the air.

The hanging piece is arranged on the carrying piece and rotates around a rotating shaft to change the position of the hanging piece.

The rotation of the pendant provides a rotating shaft and power required by the rotation of the pendant so as to change the position of the pendant.

In addition, in order to achieve the effect of continuous feeding, the number of the carrying pieces and the number of the rotating mechanism are respectively two, the number of the hanging pieces is three, each carrying piece is provided with one hanging piece, and the other hanging piece can move in the corresponding carrying piece and among the carrying pieces in a switching way.

The movement of the exchange-purpose pendant in the corresponding carrier is powered by the corresponding rotating mechanism and the rotating shaft.

Furthermore, the exchange-purpose hanger is pushed out and pulled back by a pushing-out mechanism, when pulled back, the exchange-purpose hanger is located in the corresponding carrier and can be driven by a rotating mechanism in the carrier to rotate, and when pushed out, the exchange-purpose hanger extends out of the corresponding carrier and can be driven by a rotating mechanism on the other carrier to rotate.

Since the rubber material belts 50 hung on the hangers 20 have their limitations, the rubber material belts 10 for supplying rubber material to the injection machine can be used to replace the hangers with used material and the hangers with suspended material by exchanging the hangers with each other.

In the device 10 for supplying rubber material to the injection machine, in use, the hangers 20 suspended with material are respectively hung on the first end seats 313314 and between the second end seats 412, wherein the rubber material belt 50 on the hanger 20 carried on the first end seat 313 on the left side is used as the material for use of the injection machine, and the materials suspended on other hangers are used as the spare material, so that when the material for use is replaced by a chime or by a process change, the hanger 20 carried on the first end seat 314 on the right side is exchanged with the chime, and then the hanger between the second end seats 412 is exchanged with the hanger after the material carried on the first end seat 314 to continuously supply the material to the injection machine for use, and when the hanger after the chime is exchanged between the second end seats 412, the operator can suspend the material again, the operation of replenishing the raw material is performed.

Specifically, as shown in fig. 5 and 6, the first rotating member 32 is powered by the first lifting power portion 323 to lower the first lifting seat 324 and drive the first telescopic frame 325 to move to the side of the hanging hole 26 corresponding to the hanging member to be connected, and as shown in fig. 6 and 7, the first telescopic frame 325 is inserted into the corresponding hanging hole 26 by the power provided by the first telescopic power portion 326 to simultaneously couple the two hanging members suspended on the first bearing mechanism 30 to the first telescopic frame 325, and as shown in fig. 8, the first lifting seat 325 is lifted by the first lifting power portion 323 to enable each hanging member 20 to be separated from the constraint of each first positioning column 314.

Then, the first rotary power unit 322 is used to provide power to rotate the first rotary plate 321, so that as shown in fig. 9 to 11, the hangers 20 originally carried on the

first end seats

313 and 314 can be exchanged between their positions, and the hanger with the raw material stone and the hanger with the raw material suspended thereon can be exchanged to replenish the raw material.

With the above components, the apparatus 10 for supplying rubber material to an injection molding machine can be applied as shown in fig. 14, and in combination, the first carrying mechanism 30 is located at one side of an injection molding machine 60 and feeds the used material into the injection extrusion barrel of the injection molding machine 60 to supply the material, wherein the injection molding machine 60 can reciprocate between a plurality of mold stations 61 along a linear track between a start position and an end position, and the first carrying mechanism 30 synchronously moves along the linear track along the displacement of the injection molding machine 60, so as to satisfy the material requirement of each mold station 61 by the large amount of rubber material carried by the first carrying mechanism 30, wherein the sliding of the first carrying mechanism 30 on the track is a well-known technology, the applicant does not have any further remark about this.

Accordingly, when the first carrying mechanism 30 is shifted from the initial position to the final position along with the injection machine 60, and the material is required to be used, the hanger exchange in the first carriage 30 is performed to replace the hanger of the chime for raw material, and for the re-exchange operation of the hanger of the chime for raw material, in consideration of safety, the injection machine 60 is shifted to a supplementary position and then a replacement operation is performed, the replenishing position may be the initial position or the final position, but for the convenience of replenishing the raw materials, it is appropriate to use the initial position as a supplementary position, whereby the second carrying mechanism 40 is located at a fixed point adjacent to the initial position, therefore, on-site operators can hang the rubber raw material belt on the hanging piece borne on the second bearing mechanism 40 under a safe environment to complete the raw material preparation procedure.

When the first carrying mechanism 30 is reset to the initial position, i.e., the supplement position, the hanging member exchange between the first carrying mechanism 30 and the second carrying mechanism 40 is performed, so that the device 10 for supplying rubber raw materials to the injection machine can be applied to a multi-station rubber injection molding machine to greatly improve the application range of the multi-station rubber injection molding machine and achieve the effect of automatic continuous feeding, and meanwhile, an operator can perform a raw material preparation procedure far away from the injection molding working range, thereby reducing the requirement of manpower and being beneficial to the maintenance of industrial safety.
