Description

Technical Field

[0001] This utility model relates to the field of plastic bottle production equipment technology, and in particular to an installation device for a plastic bottle lifting ring. Background Technology

[0002] PET bottles have become the mainstream packaging material for beverages due to their advantages such as light weight, good shelf life, heat resistance, and pressure resistance. Many beverages that require high-temperature sterilization before filling, such as soft drinks, juices, dairy products, and sports drinks, are also increasingly using PET bottles for packaging. Because of their low environmental pollution and energy consumption, PET bottles are gradually replacing traditional packaging materials in today's increasingly environmentally conscious world.

[0003] PET bottles, used for soy sauce bottles, large-capacity mineral water bottles, etc., require a lifting ring installation process. Chinese patent document CN208305835U discloses a lifting ring installation device for PET bottles. This device uses a positioning mechanism with a baffle to clamp the PET bottle, placing the lifting ring between the bottle mouth and the pressure block. The lifting ring is then pressed down by a telescopic component, fitting from top to bottom into the retaining ring of the PET bottle, thus achieving lifting ring installation. However, when using this lifting ring installation device, the plastic bottle needs to be manually transferred off the conveyor belt first, and after installation, the bottle needs to be transferred to the plastic bottle stacking and packaging area. Therefore, the installation efficiency and packaging efficiency of the plastic bottle still need improvement. Utility Model Content

[0028] Please see Figures 1 to 6 This utility model provides an installation device for a plastic bottle lifting ring, including a conveying mechanism 3, a telescopic component 1, a pressure block 2, two telescopic cylinders 4, two baffles 5, an installation platform 6, a first probe 7, and a controller. The telescopic cylinders 4 and the first probe 7 are electrically connected to the controller.

[0029] Specifically, the conveying mechanism 3 is used to convey plastic bottles. In actual production, blow-molded plastic bottles can be conveyed to the conveying mechanism 3 via other conveyor lines. The mounting platform 6 is horizontally fixed above the conveying mechanism 3; the telescopic component 1 is mounted on the mounting platform 6, and the pressure block 2 is located below the telescopic component 1, and the pressure block 2 is drively connected to the telescopic component 1. The telescopic component 1 and the pressure block 2 are existing technologies, and their specific working principles and usage methods can be found in Chinese patent document CN208305835U.

[0030] Specifically, the two telescopic cylinders 4 can be mirror-fixed to the left and right sides of the conveying mechanism 3 using brackets. The two baffles 5 are respectively connected to the piston rods of the two telescopic cylinders 4, and each baffle 5 includes a first stop 501 and a second stop 502 that are perpendicular to each other. The first stop 501 is parallel to the conveying direction of the conveying mechanism 3, and the second stop 502 is parallel to the width direction of the conveying mechanism 3. When the pressure block 2 moves up and down, it is located between the two baffles 5; the second stop 502 is located in front of the pressure block 2; the first probe 7 is located below the mounting platform 6 and is used to detect plastic bottles. When the first probe 7 detects a plastic bottle, the controller receives the signal from the first probe 7, thereby controlling the telescopic cylinders 4 to work, causing the two baffles 5 to close under the action of the cylinder piston rods, thus clamping the plastic bottle to be pressed and lifted. Simultaneously, the second stop 502 prevents the plastic bottle from continuing to be conveyed forward when the lifting ring is pressed. After the lifting ring is installed on the plastic bottle by the pressure block 2, the two baffles 5 are separated by the action of the cylinder piston rod, so that the plastic bottle with the lifting ring is sent into the subsequent stacking and packaging stage by the conveying mechanism 3.

[0031] Compared with existing plastic bottle lifting ring installation devices, this utility model sets up a telescopic component 1 and a pressure block 2 above the conveying mechanism 3, and sets up baffles 5 that can be closed and opened on the left and right sides of the conveying mechanism 3. Combined with the detection function of the first probe 7 on the plastic bottle, the lifting ring can be installed on the plastic bottle online on the conveying mechanism 3. After the lifting ring is installed, the plastic bottle can be directly sent to the subsequent stacking and packaging stage. Therefore, the circulation and installation time of the plastic bottle is shortened, and the installation efficiency of the lifting ring and the packaging efficiency of the plastic bottle are significantly improved.

[0032] It should be noted that before the lifting ring is installed via the pressure block 2, the lifting ring is placed at the mouth of the plastic bottle by a production worker located next to the conveying mechanism 3. The controller can preset the time for the pressure block 2 to press down and the baffle 5 to separate. This ensures that after the lifting ring is installed on the plastic bottle via the pressure block 2, the two baffles 5 can separate within the preset time, guaranteeing that the plastic bottle with the lifting ring installed will not affect the subsequent stacking and packaging process when conveyed by the conveying mechanism 3.

[0033] like Figure 1 and Figure 2 As shown, in an optional embodiment, the mounting platform 6 is provided with an opening 601 for the pressure block 2 to pass through vertically, thereby providing a stable vertical movement channel for the pressure block 2 and assisting in positioning the pressure block 2, ensuring that the pressure block 2 can be aligned with the lifting ring at the mouth of the plastic bottle each time it is pressed down, thus improving the accuracy of the lifting ring installation.

[0034] like Figure 4As shown, in an optional embodiment, the plastic bottle lifting ring mounting device further includes a second probe 9 electrically connected to the controller; the second probe 9 is disposed downwards on the mounting platform 6 and is located above the second stop 502, and is used to detect whether the plastic bottle is conveyed to the second stop 502. When the second probe 9 detects the plastic bottle, the controller, based on the detection signal of the second probe 9, controls the telescopic assembly 1 to drive the pressure block 2 to move downwards, thereby installing the lifting ring.

[0035] For example, the second probe 9 can be a photoelectric probe, but is not limited to this type.

[0036] like Figure 1 , Figure 3 as well as Figure 5 As shown, in an optional embodiment, two sets of support screws 10 are fixedly provided on the left and right sides of the conveying mechanism 3; the mounting platform 6 is sleeved on the support screws 10; and limiting nuts 11 are provided on the upper and lower sides of the mounting platform 6 on the support screws 10. In this embodiment, the support screws 10 can provide stable support for the mounting platform 6, ensuring that the mounting platform 6 remains horizontal when carrying the telescopic component 1. Moreover, the mounting platform 6 can move up and down along the support screws 10, and with the help of the limiting nuts 11 on the upper and lower sides of the mounting platform 6, the height of the mounting platform 6 can be flexibly adjusted, thereby adapting to the installation requirements of plastic bottle lifting rings of different heights and improving the versatility of the lifting ring installation device.

[0037] like Figure 1 As shown, in an optional embodiment, the conveying mechanism 3 includes a conveyor frame 301, a drive roller rotatably mounted on the conveyor frame 301, a driven roller rotatably mounted on the conveyor frame 301, a conveyor belt 302 simultaneously wound around the drive roller and the driven roller, and a drive motor connected to the drive roller. Two guide bars 12 are provided above the conveyor belt 302 along its length. Both guide bars 12 are perpendicular to the horizontal plane. In this embodiment, the two guide bars 12 can laterally limit and guide the plastic bottles on the conveyor belt, ensuring that the plastic bottles are always stably conveyed along the preset path of the conveyor belt 302, thereby accurately reaching the lifting ring installation position, so that the plastic bottles can accurately cooperate with the pressure block 2 and the baffle 5.

[0038] In an optional embodiment, the guide strip 12 is a rubber guide strip 12. When the plastic bottle comes into lateral contact or slightly collides with the guide strip 12 during transportation, the rubber guide strip 12 can buffer the impact force and prevent the plastic bottle from being scratched, deformed or even broken due to rigid friction or collision.

[0039] like Figure 4 and Figure 6As shown, in an optional embodiment, a strip profile 13 is fixed (e.g., glued) to one side of the guide strip 12 facing the outside of the conveying mechanism 3; a groove 131 is provided on the strip profile 13 along its length; a first support tube 14 extending into the groove 131 is fixedly connected to the outside of the conveying frame 301. In this embodiment, the strip profile 13 provides structural support for the rubber guide strip 12, preventing deformation and bending during long-term use, ensuring the stability of the guide strip 12's vertical and horizontal shape, and ensuring the guiding and limiting effect on the plastic bottle. Furthermore, the cooperation between the groove 131 and the first support tube 14 allows for quick assembly, disassembly, or adjustment of the guide strip 12.

[0040] like Figure 6 As shown, in an optional embodiment, a support plate 15 is horizontally connected to the outer side of the conveyor frame 301; a second support tube 16 is vertically provided on the support plate 15; the first support tube 14 is horizontally inserted through the second support tube 16; a limiting rod 8 is inserted into the second support tube 16; the lower part of the limiting rod 8 penetrates downward through the first support tube 14. In this embodiment, the support plate 15 and the second support tube 16 can provide stable support for the first support tube 14; at the same time, the first support tube 14 can move horizontally along the second support tube 16, which facilitates the adjustment of the spacing between the two guide strips 12 according to the specifications of the plastic bottle; and by vertically inserting the limiting rod 8 into the second support tube 16 and penetrating the first support tube 14, the horizontal position of the first support tube 14 can be quickly locked, preventing the guide strips 12 with the adjusted spacing from shifting due to force during use.

[0041] like Figure 6 As shown, in an optional embodiment, the first support tube 14 has a plurality of through holes 141 spaced apart for the limiting rod 8 to pass through, so that the limiting rod 8 can select the corresponding through hole 141 to insert according to the position requirements of the guide bar 12, thereby enabling the two guide bars 12 to adapt to the guiding requirements of plastic bottles of different diameters.

[0042] In an optional embodiment, the limiting rod 8 is a limiting screw, and correspondingly, the inner wall of the second support tube 16 has threads that mate with the limiting screw. Compared to a regular limiting rod 8, the limiting screw can be threadedly connected to the inner wall of the second support tube 16. When the lower part of the limiting screw penetrates the first support tube 14 downwards, it can further improve the locking effect on the first support tube 14.

[0043] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
