Description

Technical Field

[0001] This utility model relates to the field of cosmetic bottle conveying technology, specifically a cosmetic bottle conveying device with a protective device. Background Technology

[0002] In the production process of cosmetic glass bottles, multiple steps are required from raw molten glass to finished glass bottles, such as inspection and filling. In these steps, clamping conveyor belts are often used to ensure stable transport, precise positioning, and coordinated operation with other equipment. For example, in the glass bottle inspection process, the glass bottles need to be accurately transported to the front of the testing equipment. Clamping them with vertical conveyor belts on both sides can ensure that the glass bottles do not shake or tip over during transport, thereby improving the accuracy and efficiency of the inspection. In the packaging process, the glass bottles also need to be transported neatly and stably to the packaging position. Clamping conveyor belts can better control the position and spacing of the glass bottles, facilitating subsequent packaging operations.

[0003] However, existing glass bottle clamping conveyor belt drive systems typically use two sets of motors to drive the conveyor belts on both sides to achieve synchronous clamping and transmission. However, even if the same speed is set through the control algorithm, the two sets of motors may still be out of sync in actual operation. This can lead to asynchrony between the two motors, even if the same speed is set, due to differences in actual operation. This can cause the clamped bottles to shift laterally during transmission, affecting the positioning accuracy of subsequent processes (such as labeling misalignment and filling misalignment). In addition, the dual-motor drive structure significantly increases the equipment manufacturing cost and maintenance difficulty. Furthermore, existing solutions often rely on a bidirectional screw drive mechanism located in the middle of the conveyor belt to dynamically adjust the clamping distance on both sides. However, when the clamping conveyor belt is long, this structure has inherent defects: the long-distance torque transmission of the bidirectional screw will produce a small angular deviation due to the "lever arm effect," and this deviation will accumulate with the transmission distance, causing the conveyor belts on both sides to skew, resulting in inconsistent actual adjustment distances and uneven clamping force. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a cosmetic bottle conveying device with a protective device to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cosmetic bottle conveying device with a protective device, comprising a support frame, a fixed frame and two sets of mounting frames on the top of the support frame, a synchronous pulley mounted on the inner side of the mounting frame via a rotating shaft, a synchronous transmission belt meshing with the outer surface of the synchronous pulley, a driven bevel gear fixed at the top end of the rotating shaft, a connecting member mounted on one side of the top of the mounting frame, and a spline tube connected to one side of the connecting member via a bearing, a spline shaft mounted on the inner side of the fixed frame, and the spline tube... The outer surface of the device is equipped with active bevel teeth. A motor is installed inside the upper part of the fixed frame. A bidirectional screw and a support plate are installed on the inner side of the support frame. A threaded block is threadedly connected to the outer surface of the bidirectional screw. A rocker arm is connected to the inner side of the support plate through a connecting shaft. A movable opening is provided at the top of the rocker arm. Movable shafts are connected to both sides of the threaded block through connecting plates, and the movable shafts are located inside the movable opening. An actuating shaft is installed on one side of the top of the rocker arm. Actuating grooves are fixed on both sides of the bottom of the mounting frame, and the actuating shaft is located inside the actuating grooves.

[0006] Furthermore, the spline tube is sleeved on the outer surface of the spline shaft, and the spline tube and the spline shaft are slidably connected and engaged.

[0007] By adopting the above technical solution, the spline tube and spline shaft slide and mesh to achieve synchronous power transmission and axial dynamic adjustment. The torque transmission capability is improved by multi-tooth bearing, while ensuring the coaxiality error of the transmission, thus meeting the requirements of stable transmission and flexible torque adjustment in precision scenarios.

[0008] Furthermore, the output end of the motor is connected to a drive gear, and a driven gear is fixed in the middle of the outer surface of the spline shaft, with the diameter of the drive gear being larger than that of the driven gear.

[0009] By adopting the above technical solution, the rotation of the motor causes the drive gear to rotate, and the rotation of the drive gear causes the driven gear to drive the spline shaft to rotate. By adopting a reduction design in which the diameter of the drive gear is larger than that of the driven gear, the speed ratio is amplified to achieve a doubling of the motor torque and speed matching, thereby enhancing the system load capacity and optimizing energy consumption in a compact space.

[0010] Furthermore, a gearbox is fixed inside the upper part of the fixed frame, and both the driving gear and the driven gear are located inside the gearbox.

[0011] By adopting the above technical solution, the gearbox can protect the driving gear and the driven gear, and prevent workers from being accidentally injured by the gears.

[0012] Furthermore, the outer surface of the synchronous transmission belt is provided with an elastic layer, and a support strip is fixed to the bottom of the outer side of the synchronous transmission belt, and the elastic layer is made of silicone material.

[0013] By adopting the above technical solution, the elastic layer increases the contact friction with the glass bottle, and the support strip can support the glass bottle, ensuring stability during transportation.

[0014] Furthermore, a rudder is fixed to one end of the bidirectional screw.

[0015] By adopting the above technical solution, the steering wheel makes it more convenient for staff to operate the bidirectional screw.

[0016] Furthermore, the top of the support frame has sliding grooves on both sides along the length direction, and the bottom of the mounting frame has sliders fixed on both sides, with the sliders slidingly engaging with the sliding grooves.

[0017] By adopting the above technical solution, the displacement of the two sets of support frames is more stable, while ensuring the coaxiality accuracy of transmission components (such as spline shafts and gears) and avoiding abnormal wear caused by misalignment.

[0018] Furthermore, a control panel is mounted on the back of the mounting bracket, and the control panel is electrically connected to the motor.

[0019] By adopting the above technical solution, staff can adjust the motor through the control panel to control its start-stop and speed.

[0020] Furthermore, the outer surfaces of the driving gear, driven gear, spline shaft, spline tube, driving bevel gear, driven bevel gear, and bidirectional screw are all coated with lubricating oil.

[0021] By adopting the above technical solutions, the friction coefficient of each transmission component is reduced, transmission efficiency is improved, wear is reduced, and the service life of the transmission components is increased.

[0022] In summary, the present invention has the following main advantages:

[0023] 1. This utility model constructs a highly efficient synchronous transmission system for a single motor driving two conveyor belts through the coordinated design of a motor, a driving gear, a driven gear, a splined shaft, a splined tube, a driving bevel gear, and a driven bevel gear. During operation, the motor drives the driving gear to rotate, and the power is transmitted to the splined shaft through the driven gear pair. The precise cooperation between the splined shaft and two sets of splined tubes achieves symmetrical power distribution. Through the meshing transmission of the driving bevel gear and the driven bevel gear, the rotational motion is synchronously transmitted to the rotating shaft. Finally, the two sets of synchronous pulleys drive the two sets of synchronous conveyor belts to move at the same speed. This design breaks through the limitations of traditional dual-motor drives, and uses mechanical rigid transmission to ensure that the movement of the conveyor belts on both sides is strictly synchronized, fundamentally avoiding the clamping offset problem caused by motor differences. At the same time, the single-motor configuration reduces the number of drive components, significantly reducing equipment manufacturing costs and maintenance complexity.

[0024] 2. This utility model constructs a highly efficient and stable spacing adjustment mechanism through the linkage design of a bidirectional screw, threaded blocks, movable shafts, movable openings, rocker arms, actuating shafts, actuating grooves, support plates, and connecting shafts. When it is necessary to adjust the clamping spacing according to the specifications of cosmetic glass bottles, the operator rotates the bidirectional screw, driving two sets of threaded blocks to move in opposite or opposite directions along the screw axis. The linear motion of the threaded blocks is transmitted to the movable opening of the rocker arm through the movable shafts on both sides. By utilizing the sliding compression of the movable shaft in the groove, the rotational motion of the screw is converted into the lever-like oscillation of the rocker arm around the connecting shaft; the rocker arm is supported by the support plate. Under the rigid support, its end actuating shaft moves precisely along the actuating groove, synchronously pushing the two sets of mounting brackets to move symmetrically, thereby achieving the purpose of adjusting the spacing. This structure uses the lever force amplification and balance characteristics of the rocker arm to evenly distribute the screw driving force to both sides of the mounting bracket. Compared with the traditional direct drive method, it reduces the risk of lateral offset and improves displacement stability. At the same time, combined with the power synchronization technology of spline shaft and spline tube, the spacing can be dynamically adjusted in real time during equipment operation without stopping the transmission, which significantly improves production efficiency. It is especially suitable for the rapid switching and conveying of multi-specification glass bottles.

[0025] 3. This utility model constructs a stable and reliable glass bottle clamping and conveying structure through the innovative design of the elastic layer and the support strip. When the two sets of synchronous conveyor belts operate in opposite directions, the operator places the glass bottle on top of the support strip. The elastic layer and the support strip move synchronously with the synchronous conveyor belt. The flexible material of the elastic layer can adaptively conform to the curved surface of the glass bottle, increasing the contact friction while providing uniform clamping force, effectively preventing the glass bottle from shifting due to slippage or uneven clamping, and also preventing wear on the surface of the glass bottle. The support strip lifts the bottom edge of the glass bottle, preventing the glass bottle from falling between the two sets of synchronous conveyor belts due to excessive weight (after filling), thus achieving the purpose of protecting the glass bottle. This design, through the combination of the adaptive clamping of the elastic layer and the rigid lifting of the support strip, provides a reliable conveying guarantee for cosmetic glass bottles.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0036] The embodiments of this utility model will be described below based on its overall structure.

[0037] Example 1: A cosmetic bottle conveying device with a protective mechanism, such as... Figures 1-8As shown, the device includes a support frame 1, with a fixed frame 2 and two sets of mounting frames 3 on its top. A synchronous pulley 10 is mounted on the inner side of each mounting frame 3 via a rotating shaft 4. A synchronous transmission belt 9 meshes with the outer surface of the synchronous pulley 10. A driven bevel gear 24 is fixed to the top of the rotating shaft 4. A connector 7 is mounted on one side of the top of each mounting frame 3, and a spline tube 11 is connected to one side of the connector 7 via a bearing. The spline tube 11 is sleeved on the outer surface of a spline shaft 8, and the spline tube 11 and the spline shaft 8 are slidably connected and meshed. Sliding meshing enables synchronous power transmission and dynamic axial adjustment. Multi-tooth bearing enhances torque transmission capability while ensuring coaxiality error, meeting the stable transmission and flexible torque adjustment requirements in precision applications. A splined shaft 8 is mounted on the inner side of the fixed frame 2, and an active bevel gear 25 is mounted on the outer surface of the splined tube 11. A motor 5 (preferably an AC servo motor, characterized by high precision, wide speed range, and high torque output, suitable for precision transmission applications) is mounted above the interior of the fixed frame 2. The output end of the motor 5 is connected to an active gear 26. The splined shaft 8... A driven gear 27 is fixed in the middle of the outer surface of the drive gear 26, and the diameter of the drive gear 26 is larger than the diameter of the driven gear 27. The rotation of the motor 5 causes the drive gear 26 to rotate, and the rotation of the drive gear 26 causes the driven gear 27 to drive the spline shaft 8 to rotate. The reduction design of the drive gear 26 having a larger diameter than the driven gear 27 is adopted. Through speed ratio amplification, the torque of the motor 5 is multiplied and the speed is adapted, which enhances the system load capacity and optimizes energy consumption in a compact space. A bidirectional screw 14 and a support plate 17 are installed on the inner side of the support frame 1. The outer surface of the bidirectional screw 14 is threaded with a threaded block 1. 5. One end of the bidirectional screw 14 is fixed with a rudder 13, which makes it more convenient for the operator to operate the bidirectional screw 14. The inner side of the support plate 17 is connected to a rocker arm 19 through a connecting shaft 18. The top of the rocker arm 19 is provided with a movable opening 29. The two sides of the threaded block 15 are connected to movable shafts 28 through a connecting plate 16, and the movable shafts 28 are located inside the movable opening 29. A toggle shaft 21 is installed on one side of the top of the rocker arm 19. The bottom two sides of the mounting bracket 3 are fixed with toggle grooves 20, and the toggle shaft 21 is located inside the toggle grooves 20.

[0038] See Figures 1-2 In the above embodiment, a gearbox 6 is fixed inside the upper part of the fixed frame 2, and the driving gear 26 and the driven gear 27 are both located inside the gearbox 6. The gearbox 6 can protect the driving gear 26 and the driven gear 27 and prevent workers from being accidentally injured by the gears.

[0039] See Figure 1 , Figure 2 and Figure 4In the above embodiment, the top of the support frame 1 has sliding grooves 12 on both sides along the length direction, and the bottom sides of the mounting frame 3 are fixed with sliders 22, and the sliders 22 slide with the sliding grooves 12, so that the displacement of the two sets of support frames 1 is more stable, while ensuring the coaxiality accuracy of the transmission components (such as spline shaft 8, gears) and avoiding abnormal wear caused by offset.

[0040] See Figure 2 In the above embodiment, a control panel 23 is installed on the back of the fixing frame 2, and the control panel 23 is electrically connected to the motor 5. The operator can adjust the motor 5 through the control panel 23 to control its start, stop and speed.

[0041] See Figures 1-7 In the above embodiments, the outer surfaces of the driving gear 26, driven gear 27, spline shaft 8, spline tube 11, driving bevel gear 25, driven bevel gear 24, and bidirectional screw 14 are all coated with lubricating oil, which reduces the friction coefficient of each transmission component and improves transmission efficiency.

[0042] Example 2: To improve the clamping force on the glass bottle and ensure stable transportation, Example 2 is an improvement on Example 1. (See attached document for details.) Figure 8 The outer surface of the synchronous conveyor belt 9 is provided with an elastic layer 30, and a support strip 31 is fixed to the bottom of the outer side of the synchronous conveyor belt 9. The elastic layer 30 is made of silicone material. The elastic layer 30 increases the contact friction with the glass bottle, and the support strip 31 can support the glass bottle and ensure the stability during transmission.

[0043] The implementation principle of this utility model is as follows: First, the operator adjusts the spacing between the two sets of synchronous conveyor belts 9 according to the specifications of the cosmetic glass bottle. When it is necessary to adjust the clamping spacing according to the specifications of the cosmetic glass bottle, the operator rotates the bidirectional screw 14, driving the two sets of threaded blocks 15 to move in opposite or opposite directions along the screw axis. The linear motion of the threaded blocks 15 is transmitted to the movable opening 29 of the rocker arm 19 through the movable shafts 28 on both sides. By utilizing the sliding compression of the movable shafts 28 in the groove, the rotational motion of the screw is converted into the lever-like swing of the rocker arm 19 around the connecting shaft 18. Under the rigid support of the support plate 17, the rocker arm 19's end actuating shaft 21 moves precisely along the actuating groove 20, synchronously pushing the two sets of mounting brackets 3 to move symmetrically, thereby achieving the purpose of adjusting the spacing. During operation, the motor 5 drives the active gear 26 to rotate, and the power is transmitted through the driven gear 27 pair. The power is transferred to the spline shaft 8, and the precise fit between the spline shaft 8 and the two sets of spline tubes 11 achieves symmetrical power distribution. Through the meshing transmission of the active bevel gear 25 and the driven bevel gear 24, the rotational motion is synchronously transmitted to the rotating shaft 4. Finally, the two sets of synchronous pulleys 10 drive the two sets of synchronous transmission belts 9 to move at the same speed. When the two sets of synchronous transmission belts 9 are running in opposite directions, the operator places the glass bottle on the support strip 31. The elastic layer 30 and the support strip 31 move synchronously with the synchronous transmission belts 9. The flexible material of the elastic layer 30 can adaptively conform to the curved surface of the glass bottle, increasing the contact friction while providing uniform clamping force, effectively preventing the glass bottle from shifting due to slippage or uneven clamping, and also preventing wear on the surface of the glass bottle. The support strip 31 lifts the bottom edge of the glass bottle to prevent the glass bottle from falling between the two sets of synchronous transmission belts 9 due to excessive weight (after filling).

[0044] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
