Example two
As shown in fig. 8, in comparative example one, another embodiment of the present invention is: the sealing part 6 further comprises a plurality of sealing gaskets 616 fixedly connected to one ends of the sealing block 62 and the sliding rod 67.
Specifically, by providing the gasket 616, the sealing effect of the sealing block 62 is improved.
The working steps are as follows:
Step one, in the process that the preform approaches the clamping jaw 42, the preform contacts with the pressing rod 712 and pushes the pressing rod 712 to move towards the direction approaching the long plate 711, the pressing rod 712 moves to drive the second pull rod 713 to move and rotate, the second pull rod 713 moves to drive the long rod to move downwards, the concave plate 72 and the return plate 73 move downwards, and the shell 61 and the sealing plate move downwards until the top end of the shell 61 is attached to the top end of the preform;
Fixing the bottom of the preform by using a clamping plate 3, sliding a clamping jaw 42 on a T-shaped plate 41 to fix the body of the preform, and fixing the preform on the frame body 1 at the moment;
step three, the swivel 63 is controlled to rotate, a strip block 64 on the swivel 63 moves along with the swivel 63 and rotates, the strip block 64 rotates to push the sealing block 62 to move towards the direction close to the center of the shell 61, when the sealing block 62 completely clings to the rod body at the end part of the preform, the rotation is stopped, and at the moment, the vacuum tube 51 is in a sealing state with the center hole, and compared with the direct connection of the vacuum tube 51 and the preform, the connection mode is better clings to the rod body of the preform by arranging the shell 61 and the sealing block 62 to connect with the preform;
Step three, in the process that the sealing block 62 approaches to the prefabricated rod, the sliding rod 67 is contacted with the prefabricated rod at first, the sliding rod 67 is pressed to slide in the first cavity 66, the sliding rod 67 moves to drive the third pull rod 69 to move and rotate, the third pull rod 69 moves to push the sliding block 68 to move upwards, the sliding block 68 moves upwards to push the special-shaped ring 611 to move upwards until the sealing block 62 is attached to the prefabricated rod, at the moment, the sliding rod 67 completely enters the first cavity 66, and by arranging the special-shaped ring 611, in the process of sealing a central hole, if the special-shaped ring 611 does not move upwards any more, the movement of the clamping jaw 42 can be stopped, and the problems of excessive clamping and excessive pressure between the sealing block 62 and the prefabricated rod and damage to the prefabricated rod are avoided;
fourth, when the special-shaped ring 611 moves upwards, the special-shaped ring 611 pushes the Z-shaped rod 75 to move upwards, so that the first push plate 74 is driven to move upwards until the first push plate 74 is tightly attached to the return plate 73, so that the return plate 73 is not movable, the position of the return plate 73 is fixed, the special-shaped ring 611 pushes the support rod 78 to move upwards, the folding plate 77 is driven to move and fold, the folding plate 77 moves to push the second push plate 79 to be tightly attached to the shell 61, so that the position of the shell 61 is fixed, the position of the return plate 73 is fixed, and the problem that in the moving process of the frame body 1, the shell 61 moves, and a gap is formed between a prefabricated rod and the sealing block 62 is avoided;
Step five, starting the vacuum machine 5, then pushing and pulling the frame body 1 to the wire drawing tower, sliding the sliding plate 2 until the top end of the preform is consistent with the height of a clamp of the wire drawing tower, and unloading the rod lifting frame and the vacuum tube 51 after the clamp of the wire drawing tower clamps the preform.
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims. The scope of the invention is defined by the appended claims and equivalents thereof.
