AI Technical Summary
During the feeding process, existing rubber injection molding machines are prone to deflection of the material head, disengagement of the rubber material and pullback, and are poorly adaptable to rubber material of different thicknesses and cannot be adjusted in real time.
A belt-shaped rubber jaw is designed, including a gripping jaw seat, a gripping block, a gripping roller, an adjustment screw, a compression spring and a telescopic cylinder. Through the combination of these components, the belt-shaped rubber material can be effectively clamped to prevent the retraction due to its own gravity, and the adjustment device can be used to adapt to various sizes of rubber material.
It effectively avoids the deflection of the material head, the dismantling of the rubber material, and pulling back when loading the feeding mechanism. It is suitable for various sizes of rubber material, and is easy to adjust in real time, and the operator has low labor intensity and high production efficiency.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rubber injection molding machines, in particular to a belt-shaped rubber material clamping claw used for a feeding mechanism of a rubber injection molding machine. Background Art
[0002] At present, rubber injection molding equipment with large injection volume is large in size, and the feeding port is generally located in the top platform area of the equipment. The height of this area is relatively high, generally more than 2 meters. It is necessary to use the stair handrail to enter the platform before the long strip of rubber raw materials can be fed into the feeding port manually or through mechanical lifting and clamping devices. After starting the injection molding machine, the receiving mechanism is operated to continuously pull the rubber raw materials entering the feeding port into the injection molding machine before production can begin.
[0003] When feeding the strip rubber raw material, the head of the rubber raw material is easily deflected and deviates from the inlet of the injection molding machine due to its own material deformation. At the same time, due to the weight of the rubber raw material itself, during the lifting process, a pulling force will be applied to the clamping device due to its own weight, which may cause the rubber to fall out or be pulled back. When feeding, the adaptability to rubbers of different thicknesses is also poor and cannot be adjusted in real time. Summary of the invention
[0004] The utility model provides a belt-shaped rubber material clamp for a feeding mechanism of a rubber injection molding machine, which avoids the phenomena of material head deflection, rubber material falling out, and pulling back when the feeding mechanism is feeding, and is adaptable to rubber materials of various sizes and convenient for real-time adjustment.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A strip rubber material clamp for a feeding mechanism of a rubber injection molding machine, characterized in that it includes a clamping jaw seat, a clamping block, a clamping roller, an adjusting screw, a compression spring and a telescopic cylinder, wherein the front end of the clamping jaw seat is provided with a notch, and the rear end is fixedly connected to the clamping jaw mounting rod of the feeding mechanism, and the upper surface of one side of the notch of the clamping jaw seat is provided with two convex columns, and the side surfaces of the convex columns are respectively provided with transverse screw holes, and a clamping block is provided in the notch of the clamping jaw seat, and the clamping block is in the shape of a long column with an inverted L-shaped cross section, a handle at the upper end, and a clamping portion at the lower end, and three clamping rollers are provided on the lower end surface of the clamping portion of the clamping block to rotate unidirectionally in the counterclockwise direction, and the lower end surface of the other side of the notch of the clamping jaw seat is connected to the clamping jaw of the feeding mechanism. The clamping roller at the lower end of the clamping block is also provided with three corresponding clamping rollers that rotate unidirectionally in the clockwise direction, which are used to clamp the strip rubber material and prevent the rubber material from retreating due to its own gravity. The adjusting screw is a T-shaped adjusting screw. One end of the adjusting screw passes through the screw hole on the convex column and is fixed with an adjusting nut, and the other end passes through the clamping spring and is pressed on one side of the upper end handle of the clamping block. A telescopic cylinder is provided on the other side of the upper end handle of the clamping block. The telescopic cylinder and the adjusting screw are used to apply force on both sides of the clamping block handle to clamp the clamping block, and then the clamping force and gap of the clamping roller are controlled by controlling the extension and contraction of the telescopic cylinder and the tightness of the clamping spring.
[0007] A further solution is: two guide plates are also provided, and the two guide plates are respectively arranged at the front end of the clamping block and the front end of the clamping claw seat on the opposite side of the clamping block. The guide plates are two L-shaped plates extending forward, and the tail ends of the guide plates are respectively fixed to the front end of the clamping block and the front end of the clamping claw seat, and the head of the guide plates extends forward. The head of the strip rubber material can pass through between the two guide plates. During use, when the operator loads the material, the head of the strip rubber material slightly exceeds the front end of the guide plate, and only a part of the bite part of the feed port is exposed. During the feeding process, before the head of the strip rubber material enters the feed port of the rubber injection molding machine, the two guide plates can always press the head straight from both sides to prevent the head from curling, deformation, and deflection before entering the feed port, resulting in feeding failure.
[0008] The beneficial effects of the utility model are as follows: when in use, it can effectively avoid the phenomena of material head deflection, rubber material falling out, and pulling back when the feeding mechanism is feeding, and at the same time it can adapt to rubber materials of various sizes, and it is convenient to adjust in real time, the labor intensity of operators is small, and the production efficiency is high.

The adjusting screw 4 is a T-shaped adjusting screw, one end of the adjusting screw 4 passes through the screw hole on the boss 11 and is fixed with an adjusting nut, and the other end passes through the clamping spring 5 and is pressed on one side of the upper end handle of the clamping block 2. A telescopic cylinder 6 is provided on the other side of the upper end handle of the clamping block 2. The clamping block 2 is clamped by applying force on both sides of the handle of the clamping block 2 through the telescopic cylinder 6 and the adjusting screw 4, and then the clamping force and gap of the clamping roller 3 are controlled by controlling the telescopic cylinder 6 and the tightness of the clamping spring 5.
