AI Technical Summary
Traditional blow molding equipment has a slow pushing speed of the blank pusher, which affects the efficiency of subsequent blow molding processes.
An automatic blow molding machine employs a preform pushing structure, including a rotating device, a heating device, and a cylinder-driven preform pushing device. The preform is heated and quickly fed to the forming tank by a servo motor-driven conveyor belt and heating block. The rapid pushing of the preform is achieved by the cooperation of the cylinder and the mounting rod.
This improves the heating efficiency and pushing speed of the preform, ensuring that the preform does not cool down during subsequent blow molding, thus meeting production requirements.

Technical Field
[0001] This utility model relates to the field of blow molding machines, specifically a pusher structure for an automatic blow molding machine. Background Technology
[0002] A blow molding machine is a machine that blows bottles. In its simplest sense, it is a machine that can blow plastic granules (softened into liquid) or pre-made bottle preforms into bottles through certain processes. Blow molding machines are convenient, fast, and have a large production capacity. After their emergence, they replaced most manual blow molding and were adopted by most beverage companies.
[0003] In actual use, blow molding machines need to feed preforms into the molding equipment. Before feeding, they need to be heated to soften them for subsequent blow molding. The pusher of traditional blow molding equipment has a slow pushing speed, which affects subsequent blow molding and cannot meet the actual use needs. Therefore, those skilled in the art provide a pusher structure for an automatic blow molding machine to solve the problems mentioned in the background art. Utility Model Content

Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0025] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.
[0026] This application discloses a preform pushing structure for an automatic blow molding machine. (Refer to...) Figure 1 , Figure 2 , Figure 6 and Figure 7 An automatic blow molding machine has a preform pushing structure, including a mounting table 1, a rotating device 5 on the mounting table 1, a mounting cover 2 on the outside of the rotating device 5, a preform pushing device 6 on the top of the mounting table 1 and in front of the rotating device 5, a fixed mold 3 on the top of the mounting table 1 and behind the rotating device 5, a moving groove 13 on the rear side of the fixed mold 3, and two forming grooves 12 inside the moving groove 13 and the fixed mold 3. The preform is limited and formed by the cooperation between the fixed mold 3, the forming grooves 12 and the moving groove 13.
[0027] The pushing device 6 includes a second arched mounting frame 601, which is fixedly mounted on the top of the mounting table 1. A third cylinder 602 is fixedly mounted on the inner side of the second arched mounting frame 601. The output end of the third cylinder 602 passes through the second arched mounting frame 601 and is fixedly mounted on a mounting base 603. A fourth cylinder 604 is fixedly mounted on the front side of the mounting base 603. The output end of the fourth cylinder 604 passes through the mounting base 603 and is fixedly mounted on a mounting rod 605. Two second placement frames 606 are fixedly mounted on the rear side of the mounting rod 605.
[0028] Reference Figure 1 and Figure 3 The rotating device 5 includes two rotating wheels 501, which are rotatably connected to the top of the mounting table 1. A conveyor belt 502 is connected to the surface of the rotating wheels 501. A first placement rack 503 is fixedly installed on the top of the conveyor belt 502. The preforms are transported to the inside of the mounting cover 2 through the cooperation between the rotating wheels 501, the conveyor belt 502 and the first placement rack 503, thereby heating the preforms.
[0029] Reference Figure 1 and Figure 3 A servo motor 504 is fixedly installed on the right side of the bottom of the mounting table 1. The output end of the servo motor 504 passes through the mounting table 1 and is fixedly connected to the bottom of the rotating wheel 501. The servo motor 504 is used to drive the conveyor belt 502 to drive the first placement rack 503 and the preform to rotate slowly, so that the preform enters the interior of the mounting cover 2 for heating and softening.
[0030] Reference Figure 2 and Figure 3 The installation table 1 has a discharge channel 16 inside. The discharge channel 16 is located between the fixed mold 3 and the moving channel 13. The discharge is discharged after the preform is blow-molded through the discharge channel 16.
[0031] Reference Figure 1 and Figure 4 The mounting cover 2 has a second groove 8 inside, and heating blocks 9 are evenly distributed inside the second groove 8. The front right side of the mounting cover 2 has a first groove 7. The second groove 8 is used to install the heating blocks 9. The heating blocks 9 are used to heat and soften the preform to facilitate subsequent blow molding.
[0032] Reference Figure 1 and Figure 5A first arched mounting bracket 4 is fixedly installed on the top of the mounting table 1 and outside the fixed mold 3 and the moving groove 13. A second cylinder 17 is fixedly installed on the top of the first arched mounting bracket 4. The output end of the second cylinder 17 passes through the first arched mounting bracket 4 and is fixedly installed with a connecting pipe 10. A connector 11 is fixedly installed on the front side of the connecting pipe 10. The second cylinder 17 is used to push the connecting pipe 10, so that the connecting pipe 10 passes through to the top of the preform for blow molding. The connector 11 is used to connect the connecting pipe 10 to an external air supply device.
[0033] Reference Figure 1 and Figure 6 Two mounting cavities 15 are opened on the rear side of the moving groove 13. A first cylinder 14 is fixedly installed inside the mounting cavity 15. The output end of the first cylinder 14 passes through the moving groove 13 and is fixedly connected to the rear side of the fixed mold 3. The moving groove 13 is pushed away from the fixed mold 3 by the arrangement of the first cylinder 14 and the mounting cavity 15, thereby discharging the formed bottle inside the forming groove 12.
[0034] Working principle: The servo motor 504 is activated, driving the rotating wheel 501 to rotate the conveyor belt 502 and the first placement rack 503. The preform is placed inside the first placement rack 503 through the first groove 7 on the left side of the mounting cover 2. Simultaneously, the heating block 9 is activated, heating the preform inside the mounting cover 2. After heating, the fourth cylinder 604 pushes the mounting rod 605 and the second placement rack 606 to move rearward, lifting the heated preform inside the first placement rack 503. After lifting, the third... Cylinder 602 pushes the mounting base 603 upward, and the fourth cylinder 604 continues to push the mounting rod 605 and the second placement rack 606 to move backward, so that the heated bottle preform is sent into the molding groove 12 inside the fixed mold 3 and the moving groove 13. After placement, the fourth cylinder 604 pulls back the mounting rod 605 and the second placement rack 606. At the same time, the second cylinder 17 pushes the connecting pipe 10 down and penetrates into the bottle preform for blow molding. After blow molding is completed, the first cylinder 14 pulls the moving groove 13 to separate from the fixed mold 3, and the molded bottle is discharged through the discharge channel 16.
[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
