Abstract
Description
Technical Field
[0001] This utility model relates to the field of blow molding machine technology, specifically a fully automatic blow molding machine with heat preservation function. 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. Since their emergence, they have replaced most manual blow molding and are widely used by beverage companies.
[0003] The preforms are conveyed by a heated conveyor line, which is mainly used to heat the preforms to a softened state so that they can be smoothly formed during the blowing process. Specifically, the heated conveyor line carries the preforms through a heating chamber to heat them to a suitable softening temperature. Then, a robot picks up the preforms and puts them into the mold for blowing. However, there is a certain distance between the heated conveyor line and the mold. During this distance, the temperature of the preforms drops, thus reducing their ductility. To address this, we propose a fully automatic blowing machine with a heat preservation function.

The base is equipped with a blow molding mechanism. This utility model also includes a material handling robot, which includes a strip support beam. A linear drive module is provided on the top of the strip support beam. A support is provided on the top of the linear drive module.

Multiple L-shaped support arms are provided at the bottom of the strip plate. Each L-shaped support arm is equipped with a U-shaped gripper at its bottom. Two parallel strip baffles are provided on one side of the strip support beam. A heating element is provided on the opposite surface of the two strip baffles, so that the space between the two strip baffles is heated. The U-shaped gripper moves between the two strip baffles under the drive of the linear drive module.

[0025] 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.
[0026] Reference Figures 1 to 6This utility model provides a technical solution: a fully automatic blow molding machine with heat preservation function, including a base 1, on which a blow molding mechanism is provided. Figure 1 and Figure 2 As shown, the blow molding mechanism includes a frame 6 mounted on a base 1. Two parallel blow molding dies 3 are housed within the frame 6. One die 3 is fixed to the frame 6 and is a fixed die, while the other die 3 is vertically connected to guide rods 17 at its four corners, making it a movable die. The guide rods 17 are movably mounted within the frame 6. The ends of the guide rods 17 furthest from the blow molding die 3 are mounted on a connecting frame 18. The frame 6 also has a fourth telescopic mechanism 24 connected to the connecting frame 18. This fourth telescopic mechanism 24 must be parallel to the guide rods 17. Driven by the fourth telescopic mechanism 24, the guide rods 17 extend and retract within the frame 6, thereby allowing the two blow molding dies 3 to close or open.
[0027] The top of frame 6 is also equipped with an air blowing device, such as... Figure 1 and Figure 3 As shown, the blowing device includes a top frame 10 mounted on top of the frame 6. A first telescopic mechanism 11 is vertically mounted inside the top surface of the top frame 10, and the bottom of the first telescopic mechanism 11 is connected to a horizontal mounting frame 19. When the two blow molding dies 3 are closed, the horizontal mounting frame 19 is located directly above them, and multiple blowing heads 7 corresponding to the blow nozzles at the top of the blow molding dies 3 are mounted on the bottom of the horizontal mounting frame 19. When the first telescopic mechanism 11 extends, it drives the blowing heads 7 to descend and connect with the blow nozzles. To make the vertical movement of the horizontal mounting frame 19 more stable, as shown in the figure... Figure 1 As shown, at least one first guide shaft 12 parallel to the first telescopic mechanism 11 is vertically installed on the top of the horizontal mounting frame 19. The first guide shaft 12 is movably arranged in the top frame 10 and serves as a guide and support.
[0028] Among them, the blowing head 7 is connected to the high-pressure blowing equipment through the pipeline. The high-pressure blowing equipment is a high-pressure air pump. The high-pressure blowing equipment sends high-pressure gas into each blowing head 7 and blows it into each blow molding die 3.
[0029] Furthermore, a material handling robot is also installed within the blow molding mechanism. This robot includes a strip support beam 8, such as... Figure 2 As shown, one end of the strip support beam 8 is fixed inside the frame 6, while the other end is located outside the frame 6. The strip support beam 8 is connected to the base 1 through the bracket 13, and the strip support beam 8 is located above the blow molding die 3.
[0030] The top of the strip support beam 8 is equipped with a linear drive module 9, such as... Figure 5 and Figure 6As shown, a support 25 is provided on the top of the linear drive module 9. A second telescopic mechanism 23 perpendicular to the strip support beam 8 is installed on the support 25. The end of the second telescopic mechanism 23 is connected to a horizontal strip seat 22. The strip seat 22 is located outside the strip support beam 8. At least one second guide shaft 27 parallel to the second telescopic mechanism 23 is provided on the strip seat 22. The second guide shaft 27 is movably disposed in the guide seat. The guide seat is disposed on the support 25. The second guide shaft 27 can make the movement of the strip seat 22 more stable.
[0031] Next, a third telescopic mechanism 2 is vertically installed in the center of the top surface of the strip base 22. The bottom of the third telescopic mechanism 2 is connected to the horizontal strip plate 21. At least one third guide shaft 26 parallel to the third telescopic mechanism 2 is installed on the top of the strip plate 21. The third guide shaft 26 is movably disposed within the strip base 22. The third guide shaft 26 enables the strip plate 21 to be more stable. Figure 5 As shown, the strip plate 21 is located below the strip base 22. Multiple L-shaped support arms 20 are provided at the bottom of the strip plate 21. Each L-shaped support arm 20 is provided with a U-shaped gripper 28 at the bottom. The U-shaped gripper 28 is a pneumatic gripper.
[0032] The following will introduce the specific working process of the material handling robot. 1. In practical applications, such as... Figure 3 As shown, the heated conveyor line 5 for transporting bottle preforms is located below the end of the strip support beam 8 away from the blow molding die 3, allowing the heated conveyor line 5 to transport the heated bottle preforms below the strip support beam 8.
[0033] 2. The linear drive module 9 can drive the picking robot to reciprocate above the blow molding die 3 and above the heating conveyor line 5. When the picking robot is located at the heating conveyor line 5, the third telescopic mechanism 2 drives the strip plate 21 to descend, so that the U-shaped gripper 28 is placed at the bottle mouth of the heated preform. Then the second telescopic mechanism 23 extends to drive the U-shaped gripper 28 to grab the bottle mouth.
[0034] 3. The U-shaped gripper 28 has the following characteristics: Figure 5 The vertical movement capability indicated by arrow C also has the following characteristics: Figure 5 Arrow B indicates the ability to move left and right, and also has the following... Figure 5 Arrow A indicates the forward and backward movement capability. Therefore, after the U-shaped gripper 28 grasps the bottle preform's neck, it can lift the preform to a certain height and then move it towards the blow molding die 3. When the preform reaches above the blow molding die 3, the specific state is as follows: Figure 4 As shown, the U-shaped gripper 28 grasps the bottle neck and places the preform into the inner cavity of the blow molding die 3, leaving the bottle neck above the blow molding die 3;
[0035] 4. Control the first telescopic mechanism 11 to descend, so that each air blowing head 7 is positioned above the bottle mouth, and then the air blowing head 7 blows air into the bottle mouth, causing each bottle preform to be formed in the blow molding mold 3.
[0036] 5. After the disposable bottle blowing process is completed, such as Figure 4 As shown, the second telescopic mechanism 23 retracts, causing the L-shaped support arm 20 to move towards the strip support beam 8 (as shown). Figure 4 (Center arrow D) allows the blown bottle to slide off the U-shaped gripper within 28 years, thus causing the bottle to fall out of the blown mold 3.
[0037] In order to collect the fallen bottles, such as Figure 1 and Figure 3 As shown, a material trough 4 is inclined below the blow molding die 3. The bottom of the material trough 4 is connected to the base 1 through a bracket. The falling bottle can fall along the material trough 4. An easy-to-catch bottle can be placed at the bottom of the material trough 4.
[0038] Furthermore, it should be noted that when the bottle is transported from the heating conveyor line 5 to the blow molding mold 3, it takes a certain amount of time. During this time, the heated preform will be cooled. Therefore, in order to prevent the preform from cooling, two parallel strip baffles 15 are provided on one side of the strip support beam 8. Each strip baffle 15 is connected to the base 1 through a fixing frame 16.
[0039] Heating elements 14 are provided on the opposing surfaces of the two strip baffles 15. The heating elements 14 are bent heating wires or heating rods, so that the space between the two strip baffles 15 can be heated. The U-shaped gripper 28 moves between the two strip baffles 15 under the drive of the linear drive module 9. Specifically, after the U-shaped gripper 28 grabs the preform, it moves along the middle of the strip baffles 15 to the blow molding die 3. Then the picking robot directly places the preform into the blow molding die 3 to avoid the preform temperature from dropping and losing its extensibility.
[0040] Based on the above embodiments, further optimization is possible. The control module is a PLC control system, which is connected to the third telescopic mechanism 2, the blow molding die 3, the high-pressure blowing equipment, the linear drive module 9, the first telescopic mechanism 11, the heating element 14, the second telescopic mechanism 23, the heating conveyor line 5, and the fourth telescopic mechanism 24, respectively, so that the PLC control system controls each component to travel according to the set route.
[0041] Based on the above embodiments, it should be further noted that the third telescopic mechanism 2, the first telescopic mechanism 11, the second telescopic mechanism 23, and the fourth telescopic mechanism 24 are pneumatic cylinders, electric cylinders, or hydraulic cylinders. However, the fourth telescopic mechanism 24 must have a large force and stable movement to drive the opening and closing of the blow molding die 3, so the fourth telescopic mechanism 24 is preferably a hydraulic cylinder; while the linear drive module 9 is a linear motor, a belt linear drive module, or a lead screw linear drive module, etc.
[0042] Based on the above embodiments, further optimization is possible. The bottom of the strip baffle 15 is sealed by a sealing plate, and a heat insulation layer, such as an aerogel plate or a heat insulation plate, is provided on the opposing surfaces of the two strip baffles 15 to further reduce heat loss. A temperature controller connected to the heating element is provided on the surface of the strip baffle 15.
[0043] 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.
