Description

Technical Field

[0001] This utility model belongs to the technical field of plastic bottle processing equipment, specifically a bottle mouth shaping device for plastic bottle processing. Background Technology

[0002] Plastic bottles are mainly made of plastic materials and are lightweight, durable, and not easily broken. Plastic bottles widely use polyester (PET), polyethylene (PE), and polypropylene (PP) as raw materials. After adding appropriate organic solvents, they are heated at high temperatures and formed by blow molding, extrusion blow molding, or injection molding through plastic molds.

[0003] In the process of plastic bottle processing, a corresponding molding device is needed to shape the bottle mouth. However, the existing molding device still has shortcomings in actual use. When the plastic bottle is conveyed to the bottom of the molding frame by the conveyor belt, the position of the plastic bottle is prone to shift due to its own weight and inertia. This causes the bottle mouth to be unable to align with the molding area of ​​the molding frame, which will affect the molding quality of the bottle mouth. Therefore, this needs to be improved. Utility Model Content

[0006] As a preferred embodiment of this utility model, a long plate is fixedly installed in the middle of the bottom of the fixed box. The bottom end of the long plate passes through the operating table and extends to the outside of the operating table. A diagonal rod is hinged to the bottom end of the middle of the front end of the long plate. A rectangular block is hinged to the other end of the diagonal rod. The top end of the rectangular block is movably connected to the bottom end of the operating table.

[0007] As a preferred embodiment of this utility model, a second motor is fixedly installed on the front part of the right side of the bottom of the operating table, and a lead screw is fixedly sleeved on the other end of the output shaft of the second motor. The left side of the outer surface of the lead screw and the inner surface of the rectangular block are threaded together.

[0008] As a preferred embodiment of this utility model, a drive motor is fixedly installed on the left side of the bottom end of the operating table, and a drive shaft is fixedly sleeved on the other end of the output shaft of the drive motor. The top end of the drive shaft passes through the operating table and extends to the top of the operating table. An active roller is fixedly sleeved on the outer surface of the drive shaft, and the outer surface of the active roller is movably sleeved with the inner surface of the operating table.

[0009] As a preferred embodiment of this utility model, a movable shaft is movably sleeved at the right end inside the operating table, and a driven roller is fixedly sleeved on the outer surface of the movable shaft. The outer surface of the driven roller is movably sleeved with the inner surface of the operating table, and the driven roller is connected to the driving roller via a conveyor belt.

[0010] In a preferred embodiment of this invention, a double-threaded rod is movably sleeved on the right end of the operating table. Handles are fixedly sleeved on the upper and lower ends of the outer surface of the double-threaded rod, and the outer surfaces of the handles are movably connected to the outer surface of the operating table.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model is constructed by setting a first clamping rod, a first gear, a first motor, a second clamping rod, and a second gear. When the first motor is started, the rotating shaft will drive the second clamping rod and the second gear to rotate. Since the outer surface of the second gear and the outer surface of the first gear mesh with each other, the first clamping rod and the second clamping rod will rotate in opposite directions under the interaction of the second gear and the first gear. In this way, the plastic bottle can be clamped and positioned by the cooperation of the first clamping rod and the second clamping rod, thereby preventing the position of the bottle mouth from shifting due to inertia and other factors.

[0014] 2. This utility model incorporates a long plate, a diagonal rod, a rectangular block, a second motor, and a lead screw. When the second motor is started, the lead screw rotates. Since the outer surface of the lead screw and the inner surface of the rectangular block are threaded together, the rectangular block moves along with the diagonal rod under the action of the lead screw. This causes the other end of the diagonal rod to exert a pulling force on the long plate, pulling the long plate and the fixed box along the inner surface of the operating table. In this way, the clamping positions of the first and second clamping rods can be adjusted by adjusting the height of the fixed box, preventing the first and second clamping rods from clamping on the softer parts of the plastic bottle and causing deformation.

Detailed Implementation

[0021] 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 protection scope of the present utility model.

[0022] like Figures 1 to 5 As shown, this utility model provides a bottle neck molding device for processing plastic bottles, including an operating table 1. Support legs 2 are fixedly installed at the four corners of the bottom of the operating table 1. A fixed box 3 is movably sleeved at the top center of the front end of the operating table 1. A round shaft 4 is movably sleeved on the left side of the top of the fixed box 3. The top of the round shaft 4 passes through the fixed box 3 and extends to the outside of the fixed box 3, and a stop block 5 is fixedly sleeved thereon. A first clamping rod 6 is fixedly sleeved on the top of the outer surface of the round shaft 4. The top of the first clamping rod 6 and the bottom of the stop block 5 are movably connected. A first gear 7 is fixedly sleeved on the bottom of the outer surface of the round shaft 4. The top end of the first gear 7 is movably connected to the top end of the fixed box 3, the top end of the first gear 7 is movably connected to the bottom end of the first clamping rod 6, the right side of the bottom end of the fixed box 3 is fixedly installed with the first motor 8, the other end of the output shaft of the first motor 8 is fixedly sleeved with the rotating shaft 9, the top end of the rotating shaft 9 passes through the fixed box 3 and extends to the outside of the fixed box 3, the top of the outer surface of the rotating shaft 9 is fixedly sleeved with the second clamping rod 10, the bottom of the outer surface of the rotating shaft 9 is fixedly sleeved with the second gear 11, the top end of the second gear 11 is movably connected to the bottom end of the second clamping rod 10, and the outer surface of the second gear 11 is meshed with the outer surface of the first gear 7.

[0023] When the first motor 8 starts, the rotating shaft 9 will drive the second clamping rod 10 and the second gear 11 to rotate. Since the second gear 11 and the first gear 7 are meshed, the round shaft 4 will drive the first clamping rod 6 to rotate with the first gear 7 under the drive of the first gear 7. This will cause the first clamping rod 6 and the second clamping rod 10 to rotate in opposite directions. The plastic bottle is clamped and positioned by the cooperation of the first clamping rod 6 and the second clamping rod 10, preventing the position of the bottle mouth from shifting due to inertia and other factors, which would affect the shaping of the bottle mouth.

[0024] Among them, a long plate 12 is fixedly installed in the middle of the bottom of the fixed box 3. The bottom end of the long plate 12 passes through the operating table 1 and extends to the outside of the operating table 1. A diagonal rod 13 is hinged to the bottom end of the front middle of the long plate 12. A rectangular block 14 is hinged to the other end of the diagonal rod 13. The top end of the rectangular block 14 is movably connected to the bottom end of the operating table 1.

[0025] When the rectangular block 14 moves along with the diagonal rod 13, the other end of the diagonal rod 13 will exert a pulling force on the long plate 12, causing the long plate 12 to move along with the fixed box 3.

[0026] The second motor 15 is fixedly installed on the front part of the right side of the bottom of the operating table 1. The other end of the output shaft of the second motor 15 is fixedly sleeved with a lead screw 16. The left side of the outer surface of the lead screw 16 is threadedly sleeved with the inner surface of the rectangular block 14.

[0027] When the second motor 15 starts, it will cause the lead screw 16 to rotate, thereby causing the rectangular block 14, which is threadedly connected to the lead screw 16, to move.

[0028] Among them, a drive motor 17 is fixedly installed on the left side of the bottom end of the operating table 1, and a drive shaft 18 is fixedly sleeved on the other end of the output shaft of the drive motor 17. The top end of the drive shaft 18 passes through the operating table 1 and extends to the top of the operating table 1. An active roller 19 is fixedly sleeved on the outer surface of the drive shaft 18, and the outer surface of the active roller 19 and the inner surface of the operating table 1 are movably sleeved.

[0029] When the drive motor 17 starts, it will cause the drive shaft 18 to drive the drive roller 19 to rotate.

[0030] The right end of the operating table 1 is movably sleeved with a movable shaft 20. The outer surface of the movable shaft 20 is fixedly sleeved with a driven roller 21. The outer surface of the driven roller 21 is movably sleeved with the inner surface of the operating table 1. The driven roller 21 is connected to the driving roller 19 through the conveyor belt 22.

[0031] When the drive roller 19 rotates, the driven roller 21 is connected to the drive roller 19 via the conveyor belt 22. Therefore, under the combined action of the drive roller 19 and the driven roller 21, the conveyor belt 22 will rotate. At the same time, the support plate inside the conveyor belt 22 can prevent the conveyor belt 22 from collapsing.

[0032] The right end of the operating table 1 is movably fitted with a double threaded rod 23. The upper and lower ends of the outer surface of the double threaded rod 23 are respectively fixedly fitted with handles 24. The outer surface of the handles 24 is movably connected to the outer surface of the operating table 1. The upper and lower sides of the outer surface of the double threaded rod 23 are respectively threaded with guide rods 25. There are two guide rods 25. The rear ends of the two guide rods 25 are movably connected to the front end of the conveyor belt 22. The right end of the two guide rods 25 is movably fitted with a limit rod 26. The outer surface of the limit rod 26 is fixedly connected to the outer surface of the operating table 1.

[0033] When the handle 24 is turned, the double threaded rod 23 will rotate, causing the two guide rods 25, which are threadedly connected to the double threaded rod 23, to move towards each other along the outer surface of the limit rod 26.

[0034] Among them, a fixed frame 27 is fixedly installed on the rear side of the top center of the operating table 1. A pneumatic cylinder 28 is fixedly installed on the middle of the top of the fixed frame 27. The bottom end of the pneumatic cylinder 28 passes through the fixed frame 27 and extends to the bottom of the fixed frame 27, and a molding frame 29 is fixedly installed thereon. The top end of the molding frame 29 and the bottom end of the fixed frame 27 are movably connected.

[0035] When the pneumatic cylinder 28 is activated, it will cause the molding frame 29 to move, thereby molding the mouth of the plastic bottle.

[0036] Working principle and usage process of this utility model:

[0037] During processing, the operator first starts the second motor 15 according to the hardness of the plastic bottle, causing the lead screw 16 to rotate. This causes the rectangular block 14, which is threaded onto the outer surface of the lead screw 16, to move one end of the inclined rod 13. This causes the other end of the inclined rod 13 to exert a pulling force on the long plate 12, pulling the long plate 12 and the fixed box 3 to move along the inner surface of the operating table 1 until the first clamping rod 6 and the second clamping rod 10 can clamp the harder part of the plastic bottle. This prevents the first clamping rod 6 and the second clamping rod 10 from clamping the softer part of the plastic bottle and causing deformation.

[0038] The operator then starts the drive motor 17, causing the drive shaft 18 to rotate the drive roller 19. This causes the conveyor belt 22 to rotate under the combined action of the drive roller 19 and the driven roller 21. The operator then rotates the handle 24 according to the size of the plastic bottle, causing the double-threaded rod 23 to rotate. This causes the two guide rods 25, which are threaded onto the double-threaded rod 23, to move towards each other along the outer surface of the limiting rod 26 until the distance between the two guide rods 25 matches the size of the plastic bottle. The operator can then place the plastic bottle on the top of the conveyor belt 22, allowing it to be guided by the guide rods 25. When the plastic bottle moves to the bottom of the molding frame 29, the operator stops the drive motor 17 and starts the first motor 8, causing the rotating shaft 9 to drive the second clamping rod 10 and the second gear 11 to rotate. This causes the first gear 7, which meshes with the second gear 11, to rotate along with the round shaft 4 and the first clamping rod 6. As the first clamping rod 6 and the second clamping rod 10 rotate in opposite directions, the plastic bottle will be clamped and positioned. Finally, the operator starts the pneumatic cylinder 28, which causes the molding frame 29 to move down and begin molding the bottle mouth. This prevents the bottle mouth from shifting due to inertia or other factors.
