Description

A plastic bottle blow molding production equipment

Technical Field

The invention relates to the technical field related to blow molding equipment processing, and specifically provides a plastic bottle blow molding production equipment.

Background Art

Blow molding mainly refers to a common method for manufacturing hollow products. It is also the most commonly used method for processing plastic products. First, a semi-molten tubular parison is obtained by extrusion or injection molding of thermoplastic resin. Then, the parison is placed in molds of various shapes in a blow molding machine while it is hot or heated to a softened state. The vertical tubular parison is clamped by two molds and the top end is cut off. An inflation tube is inserted into the top end for inflation. With the help of gas pressure, the rubber-like parison closed in the mold cavity is inflated to make it close to the inner wall of the cavity to form a hollow product.

When blow-molding plastic bottles, there will be extra plastic on the top of the bottle mouth after the plastic bottles are formed. Generally, workers will cut it off manually when removing the plastic bottles from the mold. However, when plastic bottles are produced in large quantities, this method will lead to lower blow-molding efficiency and greatly increase labor intensity. Therefore, we need to improve the above problems.

The forming assembly includes guide rods 20 respectively installed at the outer corners of one group of mounting seats 3, sleeve rods 24 are slidably installed on the outer sides of the four guide rods 20, a second mold base 19 is commonly installed on the outer sides of one end of the four guide rods 20 away from the sleeve rods 24, a first mold base 18 is commonly installed on the outer sides of one end of the four sleeve rods 24, a first hydraulic cylinder 4 is arranged on the outer wall of the first mold base 18 away from the second mold base 19, the first hydraulic cylinder 4 is arranged on the inner side of the mounting seat 3 away from the end of the guide rod 20, rollers 16 are installed on the inner sides of both ends of the two mounting seats 3, and the two groups of rollers 16 on the same side roll on the outer side of the rail frame 15 on the corresponding side.

Please refer to Figure 3 of the specification.

The corresponding sleeve rod 24 is slidably sleeved on the outer side of the guide rod 20, and the first mold base 18 and the second mold base 19 are provided with a mold cavity of a plastic bottle body. Later, the main driving cylinder 11 can be driven to cause the overall structure of the first mold base 18 and the second mold base 19 to move synchronously.

Please refer to Figure 4 of the specification. The display box 13 is used to store plastic bottles that fall naturally after being formed. A movable clamp is set at one end of the grasping robot 42. The plastic bottle can be clamped by the set movable clamp and then flipped and inserted into the ring shell 25 inside the display box 13. The grasping dynamics of the grasping robot 42 are controlled by an external control system.

Multiple groups of positioning components include an annular shell 25 that are all installed on the inner side of the moving frame 22. A connecting seat 26 is installed on the outer side of the annular shell 25 at equal distances along the circumferential direction. A third cylinder 41 is fixedly mounted on the inner side of the connecting seat 26. The telescopic end of the third cylinder 41 slides through the inner side of the annular shell 25 and is connected to a stop block 33 at the end. An annular rod 34 is fixedly installed on the lower edge of the annular shell 25. Four sliding pads 35 are installed on the inner wall of the annular rod 34. The four sliding pads 35 are respectively arranged in a fan shape and form a circular opening in the middle.

Please refer to Figures 6 and 7 of the specification. When the grabbing manipulator 42 inserts the plastic bottle into the ring shell 25, the third cylinder 41 on one side of the ring shell 25 can be automatically driven by the externally arranged infrared sensor to press against the outside of the plastic bottle, which is helpful for cutting off the excess plastic at the bottle mouth later.

The circular opening formed in the middle of the inner side of the four arc-shaped sliding pads 35 can cooperate with the later falling of materials, and will not allow the plastic bottle to fall directly when it is fixed and pressed in the early stage.

The ring rod 34 arranged at the lower edge of the ring shell 25 can cooperate with the sliding pad 35 to move. When the plastic bottle presses the surface of the sliding pad 35, the sliding pad 35 can cooperate more flexibly.

Baffles 21 are installed on the outer wall of one side of the display box 13 and near the top, and a slide 30 is slidably fitted between the two baffles 21. A second cylinder 27 is provided on the upper end surface of the slide 30. A top seat 28 is fixedly installed on the upper surface of the second cylinder 27, and the lower surface of one end of the top seat 28 is fixedly connected to the display box 13 through a fixedly installed connecting rod 29. A motor 31 is fixedly installed on the lower surface of the slide 30, and a cutter 32 is fixedly installed on the output end of the motor 31.

Please refer to Figures 5 and 8 of the specification. The second cylinder 27 is arranged above one side of the display box 13 by means of a top seat 28 and a connecting rod 29. The second cylinder 27 can drive the slide seat 30, the motor 31 and the cutter 32 at the lower end to gradually move downward, and cooperate with the cutter 32 to cut off the excess plastic heads. The cutter 32 has cutting edges on the lower outer side and one side edge, which can quickly cut off the excess plastic heads.

A bracket 36 is fixedly installed on the outer wall of one side of the placement box 13 and close to the bottom of the moving rack 22. A negative pressure pump 40 is fixedly installed on the inner side of one end of the bracket 36. A suction cup 38 is connected to the inner side of one end of the negative pressure pump 40 through a negative pressure pipe 39 that is connected and installed. A slide 37 is fixedly installed on the lower end of the suction cup 38. A first cylinder 14 is fixedly provided on the lower end surface of the slide 37. The slide 37 and the bracket 36 are slidably matched.

Please refer to Figure 8 of the specification. The first cylinder 14 can drive the suction cup 38 to move up and down, so that the suction cup 38 can absorb the bottom of the plastic bottle corresponding to the round mouth, thereby automatically moving the plastic bottle away from under the ring shell 25.

Working principle: When in use, after the first mold base 18 and the second mold base 19 are molded together, the extrusion conveying mechanism 7 will convey the material to the space between the first mold base 18 and the second mold base 19. After filling, the mounting seat 3 at the corresponding telescopic end is moved to the bottom of the blow molding mechanism 10 under the drive of the main driving cylinder 11, and then the blow molding head of the blow molding mechanism 10 is extended to the inside of the mold under the drive of the second hydraulic cylinder 8. After the blow molding is completed and cooled, the first mold base 18 and the second mold base 19 are separated, so that the molded plastic bottle falls into the inside of the discharge port 12 and falls into the inside of the display box 13, and then the grabbing robot 42 clamps the plastic bottle through the movable clamp at the telescopic end, and then flips it into the inside of the ring shell 25 inside the display box 13, and the multiple groups of positioning components inside the ring shell 25 are positioned on the outside of the plastic bottle. The plastic bottle is clamped, and then driven by the third hydraulic cylinder 23, the moving rack 22 is pushed forward from one end of the display box 13, and the corresponding second cylinder 27 drives the slide seat 30, the motor 31, the cutter 32 and other components at the lower end to rotate above the plastic bottle, thereby cutting off the excess plastic head of the plastic bottle, and then the first cylinder 14 below drives the suction cup 38 to rise, and the suction cup 38 passes through the openings on the inner side of each slide pad 35 to adsorb the plastic bottle, and then the plastic bottle can be automatically pulled out from under the moving rack 22. In the above manner, the plastic head at the excess bottle mouth can be cut off, eliminating the subsequent manual cutting operation of the workers, and can meet the needs of large quantities of plastic bottles for blow molding, further improving the product quality of plastic bottle production, and also improving the efficiency of plastic bottle processing.
