Description

Material feeding unit and sealing strip groover thereof

Technical Field

The utility model relates to a feeding device and a sealing strip grooving machine thereof.

Background

The sealing strip is a rubber product widely used for sealing and leakage prevention isolation. Traditional sealing strip needs manual cutting notch so that install the junction at mechanical equipment, and this kind of manual cutting mode inefficiency is difficult to guarantee the grooving precision, and fragile sealing strip.

In the 70 s of the 20 th century, mechanized sealing strip grooving machines began to appear and gradually replaced manual grooving. Early sealing strip grooving machines mainly adopt saw blades or cutters to carry out grooving, and drive sealing strips to move and intermittently cut through a mechanical transmission mechanism. The grooving machine improves grooving efficiency and accuracy. But the grooving quality is difficult to ensure, burrs are easily generated at the grooving edge, and the tightness is affected. In order to solve the grooving quality problem, the sealing strip grooving machine of the mechanical cutting mode is improved. An improvement is to optimize the cutter structure, employ a finer-grained saw blade or cutter, and maintain a lower cutting speed to reduce the occurrence of kerf burrs. The other mode is that after cutting, the edge of the cutting groove is subjected to subsequent treatment by adopting a dehairing or polishing process, so that the flatness and the smoothness of the cutting groove are improved.

Mechanical cutting has become the primary cutting mode of early seal strip cutting machines through the technological improvements of the 80-90 th century of the 20 th century. The sealing strip grooving machine in a mechanical cutting mode adopts electromechanical integrated control, and a mechanical transmission and movement system drives a saw blade or a cutter which runs at high speed to automatically finish grooving operation of the sealing strip. The grooving machine has the advantages of high grooving speed and high efficiency, and grooving quality is superior to that of manual cutting, so that the requirement of industrial production is well met.

However, the existing feeding mode for conveying the sealing strips still adopts manual feeding, namely the sealing strips are placed below a cutter to be subjected to grooving treatment, or the sealing strips are automatically conveyed by using elements such as a sensor in a numerical control mode, and certain potential safety hazards exist in the manual feeding mode. And the manufacturing cost is increased by adopting a sensor numerical control mode.

The present utility model will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1, a sealing strip grooving machine comprises a frame 1. The frame 1 is provided with a feeding device 2 for conveying the sealing strips, and a grooving device 3 for moving the sealing strips to the lower part of the cutter 20 and grooving the sealing strips.

1. Feeding device 2

As shown in fig. 2 and 3, the feeding device 2 includes a conveyor belt 4 disposed at one side of the frame 1. One side of the conveyor belt 4 is provided with a driving motor 5 for driving the conveyor belt 4 to run. One side of the conveyor belt 4 is provided with a stop 6. The stopper 6 is swingably connected to the frame 1, and specifically, the stopper 6 is connected to a rotation shaft 7. The bottom of the rotating shaft 7 is connected with a ball (not shown in the figure). The ball is provided with a base 8 in a matched manner. The ball is rotatable in the base 8, and when the stop 6 is stressed, the stop 6 can swing in the horizontal direction, so that the stop 6 leaves the conveyor belt 4. Wherein a return spring (not shown) is also provided between the rotation shaft 7 and the base 8.

And a sealing strip is placed on the conveying belt 4 and moves to be abutted with the stop block 6 under the running of the conveying belt 4, so that the sealing strip is prevented from moving out of the conveying belt 4. When the stop 6 is swung away from the conveyor belt 4 by an external force, the stop 6 is made to no longer block the movement of the sealing strip, so that the sealing strip is separated from the conveyor belt 4.

A conveying track 9 is arranged on one side of the conveying belt 4. The conveying track 9 is used for entering and conveying the sealing strips for movement. A push rod 10 is slidably arranged on the conveying track 9. A plurality of tooth blocks 11 are arranged on one side of the push rod 10. The tooth block 11 is meshed with a gear 12. The gear 12 is connected with a driving shaft 13, and the top of the driving shaft 13 is connected with a turntable 14. A single push plate 15 is provided on the turntable 14. One end of the push plate 15 is connected with a rotating rod. A torsion spring 17 is arranged between the rotating rod and the push plate 15, and the rotating rod is connected with the turntable 14. Wherein, a limit plate 18 is connected to one side of the push plate 15. The limiting plate 18 is used to limit the rotatable direction of the push plate 15 to clockwise rotation. When the push plate 15 rotates to be abutted against the stop block 6, the stop block 6 is driven to swing, so that the sealing strip is not limited by the stop block 6 any more and enters the conveying track 9.

When the push rod 10 moves to the right side in the drawing, the turntable 14 rotates clockwise, so that the push plate 15 rotates, at this time, the sealing strip abutting against the stop block 6 is placed on the conveyor belt 4, and when the push plate 15 rotates to push the stop block 6 to swing, the sealing strip enters into the conveying track 9 under the action of the conveyor belt 4. After that, the push plate 15 is separated from the stop block 6, and the stop block 6 is reset. When the push rod 10 moves to the left in the drawing, the push plate 15 reversely rotates to contact with the stop block 6, and at this time, the stop plate 18 does not stop the push plate 15 any more, so that the push plate 15 rotates clockwise and cannot play a role in pushing the stop block 6. At the same time, the pusher 10 pushes the sealing strip entered into the conveying rail 9 to make a groove.

2. Grooving device 3

As shown in fig. 1, the grooving apparatus 3 includes a bracket 19 provided on one side of the conveying rail 9. The support 19 is connected with a cutter 20, and the support 19 is connected with a driving cylinder 21. The driving cylinder 21 can drive the support 19 to move up and down, so that the sealing strip below the cutter 20 is subjected to grooving treatment.

A rack gear 22 is provided on one side of the bracket 19. The pinion 22 is engaged with a driving wheel 23. The bottom of the driving wheel 23 is engaged with a sliding rod 24. Wherein, the sliding rod 24 and the gear tooth rod 22 are mutually staggered, so that the sliding rod 24 and the gear tooth rod 22 cannot interfere with each other. Wherein the thickness of the driving wheel 23 is larger than the thickness of the sliding rod 24 and the gear tooth rod 22. The driving wheel 23 is in bearing connection with the frame 1. In addition, the method comprises the following steps. The slide bar 24 is connected to the push bar 10.

When the cutter 20 moves down by the driving cylinder 21, the gear tooth bar 22 moves down, so that the driving wheel 23 rotates counterclockwise, the sliding bar 24 moves outward, and at this time, the cutter 20 performs a grooving process on the sealing strip. When the cutter 20 moves up, the sliding rod 24 moves inwards, so that the sealing strip placed in the conveying track 9 is pushed to enter below the cutter 20, at this time, the sealing strip completed by the last cutting groove is pushed to leave the cutter 20, and the process of automatic material collection and feeding is completed.

The present embodiment is only for explanation of the present utility model and is not to be construed as limiting the present utility model, and modifications to the present embodiment, which may not creatively contribute to the present utility model as required by those skilled in the art after reading the present specification, are all protected by patent laws within the scope of claims of the present utility model.
