Description

Technical Field

[0001] This utility model relates to the technical field of unloading devices, specifically an unloading mechanism for a blow molding machine. Background Technology

[0002] A blow molding machine is a device that uses a blow molding process to make plastic granules into hollow containers. Common types of machines include blow molding machines that use PP and PE for one-step molding, injection stretch blow molding machines that use PET, PC, or PP for two-step molding, and newly developed machines that use multi-layer blow molding and stretch blow molding. Most blow molding machines are still two-step blow molding machines, meaning that the plastic raw material must first be made into a preform and then blown.

[0003] Currently, after the blowing process is completed, the molded bottles need to be unloaded from the conveyor belt or transferred to another conveyor belt, a process that is usually done manually. To solve the above-mentioned technical problem, we propose a bottle unloading mechanism for blow molding machines. Utility Model Content

[0004] The purpose of this invention is to provide a bottle unloading mechanism for a blow molding machine to solve the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bottle unloading mechanism for a blow molding machine, comprising a frame, the frame having an "I"-shaped structure, a swing arm fixed at each end of the frame, a double-headed motor installed in the middle of the frame, the two swing arms being fixedly connected to one output shaft of the double-headed motor respectively, a top beam being provided at the top of the frame, a swing arm connecting seat being provided at each end of the top beam, the swing arm connecting seat being rotatably connected to the swing arm, a vertically arranged electric lead screw guide rail being installed in the middle of the top beam, a horizontally arranged support plate being fixed on the slide of the electric lead screw guide rail, the support plate being parallel to the top beam, a plurality of bottle neck connecting sleeves being fixed at equal intervals on the bottom surface of the support plate, an electric telescopic rod being fixed on the side of the bottle neck connecting sleeve, a PLC controller being fixedly installed on the top beam, the PLC controller being electrically connected to the electric telescopic rod, the double-headed motor, and the electric lead screw guide rail.

[0006] Preferably, a vertically arranged air injection pipe is fixed at the center of the bottle neck connecting sleeve, an air pump is fixed at the top of the top beam, the air pump is electrically connected to the PLC controller, a connecting pipe is connected to the air outlet of the air pump, the connecting pipe is provided with a number of connectors equal to the number of air injection pipes, the connectors are connected to the air injection pipes, and a pressure sensor is inserted and installed on the side of the bottle neck connecting sleeve, the pressure sensor is electrically connected to the PLC controller through a connecting wire.

[0007] Preferably, the connector is equipped with a fixing claw, which clamps and fixes the connector to the support plate.

[0008] Preferably, the swing arm consists of an active swing arm and a driven swing arm, and the length of the active swing arm is equal to the length of the driven swing arm.

[0009] Compared with the prior art, the beneficial effects of this utility model are: when this utility model is running, the double-head motor drives the swing arms at both ends of the frame to swing, thereby realizing the unloading or transfer of bottles. The support plate is driven by the electric screw guide rail to move up and down. When grabbing the bottle, the support plate descends so that the bottle mouth connecting sleeve at the bottom of the bottle covers the bottle mouth. Then the bottle is held by the extension end of the electric telescopic rod.

[0010] This invention can simultaneously grasp bottles and test their airtightness. When the bottle neck connector covers the bottle neck, the air injection tube is inserted into the bottle. The air pump runs and injects air into the bottle through the air injection tube, causing the internal air pressure to rise and then stop. The air pressure sensor can detect the air pressure in the air injection tube. When the value measured by the air pressure sensor reaches its maximum, it needs to remain unchanged for a period of time. If the value drops, it indicates that the bottle is not airtight enough.

[0017] Please see Figure 1-3 In this embodiment of the present invention, a bottle unloading mechanism for a blow molding machine includes a frame 1, which has an "I"-shaped structure. A swing arm 2 is fixed at each end of the frame 1. Each swing arm 2 consists of an active swing arm 3 and a driven swing arm 4, with the length of the active swing arm 3 equal to the length of the driven swing arm 4. A double-headed motor 14 is installed in the middle of the frame 1, and the two swing arms 2 are respectively fixedly connected to one output shaft of the double-headed motor 14. A top beam 6 is provided at the top of the frame 1, and a swing arm connecting seat 5 is provided at each end of the top beam 6. The connecting seat 5 is rotatably connected to the swing arm 2. A vertically set electric screw guide rail 7 is installed in the middle of the top beam 6. A horizontally set support plate 12 is fixed on the slide table of the electric screw guide rail 7. The support plate 12 is parallel to the top beam 6. Multiple bottle neck connecting sleeves 16 are fixed at equal intervals on the bottom surface of the support plate 12. An electric telescopic rod 15 is fixed on the side of the bottle neck connecting sleeve 16. A PLC controller 19 is fixedly installed on the top beam 6. The PLC controller 19 is electrically connected to the electric telescopic rod 15, the double-head motor 14, and the electric screw guide rail 7.

[0018] A vertically arranged air injection pipe 13 is fixed at the center of the bottle neck connecting sleeve 16. An air pump 8 is fixed at the top of the top beam 6. The air pump 8 is electrically connected to the PLC controller 19. A connecting pipe 9 is connected to the air outlet of the air pump 8. The connecting pipe 9 is provided with a number of connectors 10 equal to the number of air injection pipes 13. The connectors 10 are connected to the air injection pipes 13. A pressure sensor 18 is inserted and installed on the side of the bottle neck connecting sleeve 16. The detection end of the pressure sensor 18 is inserted into the air injection pipe 13.

[0019] A fixing claw 11 is installed on the connector 10, and the fixing claw 11 is clamped and fixed on the support plate 12.

[0020] The working principle of this utility model is as follows: When this utility model is running, the double-head motor 14 drives the swing arms 2 at both ends of the frame 1 to swing, thereby realizing the unloading or transfer of the bottle. The support plate 12 is driven by the electric screw guide rail 7 to move up and down. When grabbing the bottle, the support plate 12 descends so that the bottle mouth connecting sleeve 16 at the bottom of the bottle covers the bottle mouth. Then the bottle is held by the telescopic end of the electric telescopic rod 15.

[0021] This invention can detect the airtightness of a bottle while gripping it. When the bottle neck connecting sleeve 16 is fitted over the bottle neck, the air injection tube 13 is inserted into the bottle. The air pump 8 runs and injects air into the bottle through the air injection tube 13, causing the air pressure inside the bottle to rise and then stop. The air pressure sensor 18 can detect the air pressure in the air injection tube 13. When the value measured by the air pressure sensor 18 reaches its maximum, it needs to remain unchanged for a period of time. If the value drops, it indicates that the bottle is not airtight enough.
