[0001] This utility model relates to the field of blow molding machine technology, specifically a fully automatic blow molding machine with a structure to prevent raw material spillage. Background Technology

[0002] A blow molding machine is a machine that blows bottles into shape from softened preforms. Blow molding machines are convenient, fast, and have a high production capacity, and since their emergence, they have replaced most manual blow molding processes and are widely adopted by beverage companies. The preforms are transported by a heated conveyor line (i.e., a rotary conveyor line), which primarily heats the preforms to a softened state for smooth shaping during the blowing process. Existing blow molding machines still involve distributed operations; preform feeding, heating, and blowing must be completed separately. This process is not only cumbersome but also prone to dropping and tilting during handling, leading to increased defective products. Therefore, we propose a fully automatic blow molding machine with an anti-spillage structure. Utility Model Content

[0022] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figures 1 to 7 This utility model provides a technical solution: a fully automatic blow molding machine with an anti-spilling structure, including a preform feeding mechanism 10 and a rotary conveyor line 14. The rotary conveyor line 14 is located on one side of the preform feeding mechanism 10. Preforms 13 for bottle production are poured into the preform feeding mechanism 10 and then conveyed to the rotary conveyor line 14 via the preform feeding mechanism 10. Figure 1 As shown, the preforms 13 are placed at equal intervals on the rotary conveyor line 14.

[0024] A heating device, a forming mechanism, and a unloading robot are sequentially arranged on the side of the rotary conveyor line 14 away from the preform feeding mechanism 10. The preform feeding mechanism 10, the rotary conveyor line 14, the heating device, the forming mechanism, and the unloading robot are all mounted on the base 1. The heating device, the forming mechanism, and the unloading robot will be described one by one below:

[0025] First, a heating device is installed on the other side of the rotary conveyor line 14, such as... Figure 1 and Figure 3 As shown, the heating device includes a baking oven 15 with an open bottom. The bottom of the baking oven 15 is provided with multiple support legs 17, which are mounted on the base 1.

[0026] Heaters 16 are provided on both sides of the inner wall of the baking oven 15. After the heaters 16 heat up, a channel for heating the preform 13 is formed inside the baking oven 15. The preform 13 passes through this channel. The baking oven 15 has a long and narrow structure, which allows the preform 13 sufficient heating time as it passes through the interior of the baking oven 15. It should be noted that the bottle mouth of the preform 13 faces downwards and is exposed below the rotary conveyor 14. Specifically, the bottle body of the preform 13 passes through the baking oven 15, so that the preform 13 transported on the rotary conveyor 14 passes through the heating device and is baked and softened.

[0027] Secondly, a forming mechanism is provided on one side of the heating device. The forming mechanism includes two molds 21 symmetrically arranged on both sides of the rotary conveyor line 14, and both molds 21 are mounted on the telescopic drive device. Figure 1 and Figure 6 As shown, the telescopic drive device includes guide posts 11 vertically mounted at the four corners of the mold 21, with the guide posts 11 extending towards both sides of the rotary conveyor line 14. Figure 2 As shown, the guide columns 11 are movably arranged in the frame 2, which is set on the base 1. The ends of the guide columns 11 away from the mold 21 are all installed on the connecting frame 22. The frame 2 is also provided with a third telescopic mechanism 28 connected to the connecting frame 22. The third telescopic mechanism 28 is parallel to the guide columns 11. When the third telescopic mechanism 28 extends or retracts, it can drive the guide columns 11 in the frame 2. Under the drive of the telescopic drive device, the two molds 21 are closed or opened.

[0028] It should be noted that, specifically as follows Figure 7 As shown, the rotary conveyor line 14 is located below the middle of the two molds 21, and the position of the preform 13 corresponds to the two molds 21. Specifically, when the two molds 21 are closed, multiple heated preforms 13 are clamped in the cavity of the mold 21.

[0029] Below the two molds 21, there is also a blow molding mechanism, for example... Figure 7 As shown, the blow molding mechanism is located below the rotary conveyor line 14 and corresponds to the position of the preform 13. The blow molding mechanism includes a support frame 23 disposed between two frames 2. A fourth telescopic mechanism 27 is vertically disposed in the middle of the support frame 23. A second strip frame 25 parallel to the rotary conveyor line 14 is installed on the top of the fourth telescopic mechanism 27. The second strip frame 25 is provided with multiple air nozzles 24 corresponding to the cavities of the mold 21. The air nozzles 24 are connected to the air blowing device through pipes. When the two molds 21 are closed, the air nozzles 24 rise under the drive of the fourth telescopic mechanism 27, so that the air nozzles 24 align with the bottle mouth of the preform 13, and then blow air into the preform 13, so that the preform 13 is formed in the mold 21.

[0030] To make the up-and-down movement of the second strip frame 25 more stable, at least one second guide rod 26 is vertically provided at the bottom of the second strip frame 25. The second guide rod 26 is movably placed on the support frame 23. The second guide rod 26 can enhance the strength and movement stability of the second strip frame 25.

[0031] Finally, this application also includes a feeding robot located on one side of the molding mechanism, such as... Figure 4 As shown, the unloading robot includes a support truss 6, which is mounted on the base 1, and the rotary conveyor line 14 passes through the support truss 6.

[0032] The top of the support truss 6 is provided with an installation beam 8 parallel to the rotary conveyor line 14. The top two sides of the support truss 6 are respectively provided with guide rails 7 perpendicular to the rotary conveyor line 14. The two ends of the installation beam 8 are connected to the guide rails 7 by sliders. The top of the installation beam 8 is connected to the first telescopic mechanism 9. The first telescopic mechanism 9 is parallel to the guide rails 7 and is installed on the support truss 6. When the first telescopic mechanism 9 extends and retracts, it can drive the installation beam 8 to reciprocate along the guide rails 7.

[0033] like Figure 4 and Figure 5 As shown, a downwardly extending mounting frame 5 is installed in the middle of the mounting beam 8. The bottom of the mounting frame 5 is horizontally provided with a mounting seat 29. Below the mounting seat 29 is a first strip frame 4 parallel to the rotary conveyor line 14. The top of the first strip frame 4 is vertically provided with a second telescopic mechanism 20 and a first guide rod 19. The first guide rod 19 is movably arranged in the mounting seat 29, and the second telescopic mechanism 20 is installed on the mounting seat 29.

[0034] Below the first strip frame 4, there are multiple suction cup manipulators 18 that correspond to the preforms 13 after molding. The suction cup manipulators 18 are connected to the negative pressure device through pipes. One side of the first strip frame 4 is provided with a downward inclined guide trough 3, which is located inside the support truss 6.

[0035] When the first telescopic mechanism 9 drives the mounting beam 8 to reciprocate, the suction cup robot 18 can move in the direction of the suction cup robot 18 or move away from the suction cup robot 18. First, the suction cup robot 18 stops above the rotary conveyor line 14. Then, the suction cup robot 18 descends to pick up each blown bottle. Then, the suction cup robot 18 rises and moves above the guide trough 3 under the drive of the first telescopic mechanism 9. The suction cup robot 18 releases the bottle and lets the bottle fall along the guide trough 3. The container waiting to pick up the bottle is placed at the bottom of the guide trough 3.

[0036] Based on the above embodiments, the preforms 13 are placed at intervals on the rotary conveyor line 14. As the rotary conveyor line 14 rotates, the preforms 13 are heated by the baking oven 15, which softens the preforms 13. Then, the preforms 13 are driven by the rotary conveyor line 14 to travel between the molds 21. The molds 21 are closed by the third telescopic mechanism 28 to clamp the preforms 13. Then, the fourth telescopic mechanism 27 is controlled to lift and drive the air nozzle 24 to connect with the bottom mouth of the preforms 13, so that the preforms 13 are blown into shape by the air nozzle 24.

[0037] In use, this application connects to components such as the first telescopic mechanism 9, the preform feeding mechanism 10, the rotary conveyor line 14, the heater 16, the second telescopic mechanism 20, the mold 21, the fourth telescopic mechanism 27, the third telescopic mechanism 28, the negative pressure device, and the blowing device through a PLC intelligent control system, thereby automating the entire process. The preform 13 can travel stably under the conveying of the rotary conveyor line 14 without falling off. Moreover, the mold 21's mold closing and opening process is stable, enabling rapid molding of the preform. The molded bottles are then picked up by the unloading robot. The entire process operates stably without any falling off.

[0038] Based on the above embodiments, further optimizations can be made. The top of the baking oven 15 is detachably equipped with a protective cover 12, which is connected to the baking oven 15 by a latch or bolt. When the protective cover is opened, it is convenient to maintain the inside of the baking oven 15.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
