[0002] A blow molding machine is a plastic processing machine, mainly used to produce hollow plastic products such as bottles, barrels, cans, etc. The working principle of a blow molding machine is to place a tubular plastic preform obtained by extrusion or injection molding of a thermoplastic resin in a split mold while it is still hot (or heated to a softened state). After closing the mold, compressed air is immediately introduced into the preform to inflate the plastic preform and cling to the inner wall of the mold. After cooling and demoulding, various hollow products are obtained. It is suitable for the production of hollow products of various sizes and shapes, and has the advantages of high production efficiency and easy operation.

[0003] In the prior art, the blank is usually in a tubular shape. After being ejected, the blank needs to be under-encapsulated and then placed into the mold. However, during the operation of the blow molding machine, improper operation by the operator may cause the blank to be positioned inaccurately after being ejected, making it impossible for the blank to enter the mold correctly. At this time, manual adjustment of the blank's position is usually required. Due to manual intervention, on the one hand, the production cycle of the product is lengthened, and on the other hand, it may pose a threat to the personal safety of the operator.

[0004] Therefore, the utility model provides a material guiding device for a blow molding machine to solve the above problems. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The utility model provides a material guiding device for a blow molding machine, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the material guiding device includes a fixed plate 1, a mounting frame 2 fixedly mounted on the fixed plate 1, a cylinder 3 movably mounted on the mounting frame 2, a rotating shaft 5 fixedly mounted on the fixed plate 1, a gear 6 rotatably mounted on the side surface of the rotating shaft 5, a rotating plate 8 rotatably mounted on the side surface of the rotating shaft 5, a traction plate 4 fixedly mounted on the rotating plate 8, a connecting plate 10 movably mounted on one side of the rotating plate 8, and a guide rod 12 arranged on the connecting plate 10, and the movable end of the cylinder 3 is movably connected to the traction plate 4.

[0025] One side of the gear 6 is fixedly connected to a plug post 7 , and a first socket 9 adapted to the plug post 7 is provided on the rotating plate 8 . One side of the gear 6 and one side of the rotating plate 8 fit together, and the plug post 7 is inserted into the inside of the first socket 9 .

[0026] The gear 6, rotating plate 8, connecting plate 10 and related parts of the material guiding device are provided with two groups, among which only one rotating plate 8 is provided with a traction plate 4. When the material guiding device is in use, it needs to be installed between the blank discharge port and the mold. After the blank is ejected, it can pass between the two guide rods 12. The guide rods 12 can limit the blank, reduce the possibility of the blank being offset, and enable the blank to accurately enter the mold, thereby effectively reducing manual intervention, shortening the product cycle, and improving production safety.

[0027] The two rotating plates 8 are connected to the two gears 6 through the plug column 7, and the two gears 6 are meshed with each other. When the cylinder 3 is working, it can drive one of the rotating plates 8 to swing through the traction plate 4. When one of the rotating plates 8 swings, the gear 6 connected to it will also rotate on the rotating shaft 5. Since the two gears 6 are meshed with each other, the currently rotating gear 6 can drive the other gear 6 to rotate, so that the two rotating plates 8 swing in opposite directions. The guide rod 12 is installed on the connecting plate 10, and the connecting plate 10 is installed on the rotating plate 8. Therefore, the rotating plate 8 can drive the guide rod 12 to swing together, thereby changing the spacing between the two guide rods 12. In actual use, the staff can adjust it by themselves according to the width of the blank, which has high flexibility.

[0028] Furthermore, in order to improve the stability of the connecting plate 10 when it moves, as shown in FIG. Figure 1 、 Figure 2 and Figure 3 As shown, both sides of the rotating plate 8 are fixedly connected with slide rails 16 , and both sides of the connecting plate 10 are fixedly connected with slide bars 17 , which are inserted into the interior of the slide rails 16 .

[0029] The connecting plate 10 can slide on the rotating plate 8, and the guide rod 12 will also move with it when the connecting plate 10 moves. This setting is also used to change the distance between the two guide rods 12 to improve the flexibility of the device. When the connecting plate 10 slides on the rotating plate 8, the slide bars 17 on both sides of the connecting plate 10 will also slide inside the slide rail 16. The setting of the slide bar 17 and the slide rail 16 provides a limiting function for the connecting plate 10, thereby improving the stability of the connecting plate 10 when it moves.

[0030] It should be noted that in order to improve the stability of the connecting plate 10 when it is installed on the rotating plate 8, Figure 2 、 Figure 3 and Figure 5 As shown, the side of the rotating plate 8 away from the connecting plate 10 is fixedly connected to the limiting shell 20, and the end of the limiting shell 20 away from the rotating plate 8 is fixedly connected to the limiting plate 24. The interior of the limiting shell 20 is slidably connected to a pressure plate 21, and one side of the pressure plate 21 is fixedly connected to a pull rod 25, which passes through the limiting plate 24, and the other side of the pressure plate 21 is fixedly connected to an insertion rod 22. Evenly distributed second insertion holes 18 are provided on the connecting plate 10, and a through hole 19 is provided on the rotating plate 8. The insertion rod 22 is inserted into the interior of the second insertion hole 18 through the through hole 19.

[0031] A spring 23 is fixedly connected to one side of the pressing plate 21 away from the insertion rod 22 , and one end of the spring 23 away from the pressing plate 21 is fixedly connected to one side of the limiting plate 24 .

[0032] The insertion rod 22 is fixed to the connecting plate 10 by being inserted into the second insertion hole 18 on the connecting plate 10. There are multiple second insertion holes 18. This arrangement enables the connecting plate 10 to be adjusted in multiple levels on the rotating plate 8. Before adjusting the connecting plate 10, it is necessary to pull the pull rod 25. The pull rod 25 is connected to the insertion rod 22 through the pressure plate 21. When the pull rod 25 is pulled, the insertion rod 22 can be moved out of the second insertion hole 18 on the connecting plate 10, and the spring 23 will also be compressed. At this time, the connecting plate 10 that has lost its fixation can slide on the rotating plate 8. After the other second insertion holes 18 on the connecting plate 10 are aligned with the through hole 19, the pull rod 25 can be released, the spring 23 will release the pressure instantly, and push the insertion rod 22 through the pressure plate 21 to make it inserted into the second insertion hole 18. At this time, the adjustment of the connecting plate 10 is completed, and the connecting plate 10 is also stably fixed on the rotating plate 8.

[0033] Furthermore, in order to improve the stability of the guide rod 12 during operation, Figure 1 、 Figure 2 and Figure 3 As shown, a mounting hole 11 is provided on the connecting plate 10, and the side surface of the guide rod 12 fits with the inner wall of the mounting hole 11. The side surface of the guide rod 12 is fixedly connected to a limiting ring 13, and one side of the limiting ring 13 fits with one side of the connecting plate 10. The side surface of the guide rod 12 is provided with a threaded section, and a threaded barrel 15 is screwed on the threaded section. The side surface of the guide rod 12 is sleeved with a washer 14, and one side of the washer 14 fits with the other side of the connecting plate 10, and the other side of the washer 14 fits with one side of the threaded barrel 15.

[0034] After the guide rod 12 is inserted into the connecting plate 10 through the mounting hole 11, it is necessary to put a washer 14 on the side surface of the guide rod 12, and then screw the threaded barrel 15 on the threaded section to fix the guide rod 12 on the connecting plate 10. The setting of the limiting ring 13 and the threaded barrel 15 provides stability for the guide rod 12 during operation. The washer 14 is located between the threaded barrel 15 and the connecting plate 10, which plays a good buffering role, avoids hard contact between the two, reduces the possibility of damage, and helps to improve its service life.

[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
