Description

Technical Field

[0001] This utility model relates to the field of packaging machinery technology, and in particular to a rotary bottle feeding mechanism, specifically a rotary bottle feeding mechanism for bottling production lines, applicable to automated filling and packaging processes in industries such as beverages, pharmaceuticals, and cosmetics. Background Technology

[0002] In bottling production lines, the bottle feeding mechanism is one of the key pieces of equipment, responsible for the orderly and continuous transport of bottles from the stacking position to the filling or sealing station. Common bottle feeding mechanisms in existing technologies include belt conveyors, vibratory feeders, and rotary table systems. Among these, rotary table bottle feeding mechanisms are widely used due to their compact structure and high efficiency. However, traditional rotary table mechanisms have the following common problems and limitations:

[0003] Bottles are prone to idling under low load: When there are few bottles on the rotating plate, the bottles are prone to idling in the center area of ​​the plate due to insufficient squeezing force, and cannot effectively enter the bottle exit track, resulting in interruption of the production process.

[0004] Fixed guide mechanisms are prone to causing bottle jamming or tipping: To solve the above problems, traditional solutions often use fixed springs or baffles as guide devices to push the bottles towards the edge of the turntable. For example, when the bottle load is full, rigid collisions or excessive friction will occur between the fixed baffle and the bottle, which can easily cause the bottle to jam, tip over, or even break, especially affecting plastic or glass bottles on high-speed production lines.

[0005] Poor adaptability and cumbersome adjustments: Existing mechanisms generally lack flexibility and are difficult to adapt quickly to bottles of different sizes. The adjustment process often requires stopping the machine and manually replacing parts, such as guide plates and tracks, which not only reduces equipment utilization but also increases the labor intensity of operators and production costs.

[0006] To overcome these shortcomings, the industry has made some attempts at improvement. For example, Chinese patent CN216334518U discloses a multi-channel high-speed bottle-scraping turntable, which uses multiple parallel tracks to form a transmission plane to replace the traditional integral rotating disc, aiming to avoid bottle tipping caused by centrifugal force. While this design improves the transmission speed to some extent, its structure is complex, requiring multiple tracks and independent drive systems to work together, resulting in high manufacturing costs and maintenance difficulties. Furthermore, it does not solve the problem of bottles remaining in the central area of ​​the turntable.

[0007] For example, CN219620115U proposes a dual-track bottle feeding turntable mechanism. By setting parallel dual tracks and switchable channel bolts on the turntable surface, it can transport bottles of different sizes, eliminating the hassle of replacing parts. The innovation of this solution lies in the flexibility of the tracks; however, its core bottle guiding method still relies on fixed arc-shaped plates and levers, and it does not provide an effective solution to the problem of bottles getting stuck when the turntable is empty or fully loaded.

[0008] Furthermore, in high-speed operating scenarios, traditional rotary bottle feeding methods suffer from insufficient stability. For example, CN219620115U proposes a large rotary bottle conveying mechanism, which increases operational stability and complies with GMP standards by replacing V-belt drive with gear meshing and designing a hollow structure at the center of the rotary table. However, this still only addresses the level of transmission method and structural optimization, and does not address the fundamental issue of the bottle guiding mechanism.

[0009] Therefore, there is an urgent need in this field for a bottle feeding mechanism that is simple in structure, easy to adjust, operates smoothly, and can fundamentally solve the problems of bottle jamming and tipping. An ideal solution should be able to simulate the gentleness and adaptability of human hand operation, ensuring smooth and damage-free bottle delivery under various load conditions. Utility Model Content

[0010] To address the shortcomings of existing technologies, the purpose of this invention is to provide a rotary bottle feeding mechanism that solves the problems of bottle jamming, tipping, and poor adaptability in existing technologies. This invention simulates the action of a human hand to gently and controllably guide the bottle, while introducing an adjustable mechanism to enhance the versatility and reliability of the mechanism.

[0011] The above-mentioned utility model objective is achieved through the following technical solution:

[0012] This utility model provides a rotary bottle feeding mechanism, including a bottle placement platform, a rotary disk, a bottle dispensing track, a drive motor, a rotary disk drive shaft, a drive gear, a bottle-dispensing block, a dispensing amplitude adjustment block, a dispensing swing arm, and a dispensing shaft. The bottle placement platform is used to place a tray of bottles. The rotary disk is connected to the drive motor via the rotary disk drive shaft to achieve continuous rotation. The bottle-dispensing block is mounted on the dispensing shaft and achieves a back-and-forth dispensing action through the transmission of the dispensing swing arm and the drive gear. The dispensing amplitude adjustment block is used to adjust the swing amplitude of the bottle-dispensing block. The bottle dispensing track is used to guide the bottles to be output in an orderly manner.

[0013] According to one embodiment of the present invention, the lower part of the bottle-pulling block is provided with a slot for adjusting the distance between the head of the bottle-pulling block and the outer ring of the rotating disk to accommodate bottles of different sizes.

[0014] According to one embodiment of the present invention, the agitation amplitude adjustment block adopts a slider structure, and the swing angle of the agitator arm can be adjusted manually or automatically to control the movement range of the bottle agitator.

[0015] According to one embodiment of the present invention, the drive motor is a stepper motor or a servo motor, and the rotation speed of the rotating disk is controlled by a frequency converter to achieve precise adjustment of the bottle feeding speed.

[0016] According to one embodiment of the present invention, the surface of the rotating disk is provided with anti-slip texture or rubber coating to increase the friction with the bottle and prevent the bottle from slipping.

[0017] According to one embodiment of the present invention, it also includes a sensor system for detecting the number of bottles on the rotating disk. When there are fewer bottles, the enhanced agitation mode of the bottle-pulling block is automatically activated to prevent the bottles from spinning idly in the center of the disk.

[0018] According to one embodiment of the present invention, the bottle-pulling block is made of an elastic material, such as polyurethane or rubber, to reduce the impact on the bottle and prevent the bottle from breaking.

[0019] According to one embodiment of the present invention, the turntable drive shaft and the actuation shaft are fixed by bearing seats to ensure smooth rotation and reduce vibration and noise.

[0020] According to one embodiment of this utility model, the bottle dispensing track is designed with an adjustable width, and adapts to different bottle diameters through the guide rail and locking device to ensure smooth bottle output.

[0021] According to one embodiment of this utility model, the entire mechanism is made of stainless steel or aluminum alloy, which has the characteristics of corrosion resistance and easy cleaning, and is suitable for industries with high requirements such as food and pharmaceutical hygiene.

[0022] In summary, compared with the prior art, the present invention has at least one of the following beneficial technical effects:

[0023] 1. This utility model employs a bottle-feeding block combined with an adjustable mechanism, simulating human hand movements for the first time in a rotary bottle feeding mechanism. Unlike fixed springs or pneumatic methods, the movement is gentle and adjustable, reducing the risk of bottle damage. Through mechanical linkage design, the rotational motion of the drive motor is converted into the oscillation of the bottle-feeding block, resulting in a simple, reliable, and non-obvious structure. The adjustable block and slot design enable rapid adaptation to different bottle types, overcoming the limitations of existing technologies. The mechanism is suitable for various production lines, is easy to operate, has low maintenance costs, and improves production efficiency and bottle conveying stability.

[0024] 2. The core innovation of this mechanism lies in replacing the traditional fixed spring baffle with a reciprocating bottle-dispensing block. Through a drive motor and a series of transmission mechanisms (such as drive gears, a lever arm, and a lever shaft), it transforms rotational motion into a continuous, gentle back-and-forth dispensing motion of the bottle-dispensing block, mimicking the action of a human hand. This dynamic bottle-dispensing method effectively avoids the problems of bottle jamming or bottles being knocked over due to rigid collisions when there are many bottles on the turntable. Simultaneously, when there are few bottles, it reliably guides the bottles in the center of the turntable to the bottle-dispensing track, solving the problem of bottles spinning idly in the center of the turntable and failing to be dispensed.

[0025] 3. Secondly, this mechanism demonstrates excellent adaptability and flexibility. The lower part of the bottle-dispensing block has slots to adjust the distance between its head and the outer ring of the turntable; simultaneously, it features an independent adjustment block for controlling the swing range of the bottle-dispensing block. These two adjustment functions work together to allow the mechanism to quickly adapt to bottles of different sizes, eliminating the hassle of replacing parts, significantly improving the equipment's responsiveness to different production needs, and reducing adjustment time and production costs.

[0026] 4. Finally, this design achieves stable and controllable bottle conveying through mechanical linkage, with a relatively simple and reliable structure. Its smooth agitation reduces the risk of bottle damage, while its efficient bottle guiding capability ensures smooth connection with subsequent filling or labeling processes. This not only helps ensure the continuous and stable operation of the production line and reduces downtime caused by bottle jams or tipping, but also improves overall production efficiency and automation levels.

[0033] Example 1:

[0034] Reference Figure 1 and Figure 2 This utility model discloses a rotary bottle feeding mechanism, comprising a bottle placement platform 1, a rotary disk 2, a bottle dispensing track 5, a drive motor 11, a rotary disk drive shaft 6, a drive gear 7, a bottle-dispensing block 4, a dispensing amplitude adjustment block 8, a dispensing swing arm 9, and a dispensing shaft 10; the bottle placement platform 1 is used to place a tray of bottles 3; the rotary disk 2 is connected to the drive motor 11 via the rotary disk drive shaft 6 to achieve continuous rotation; the bottle-dispensing block 4 is mounted on the dispensing shaft 10 and achieves a back-and-forth dispensing action through the transmission of the dispensing swing arm 9 and the drive gear 7; the dispensing amplitude adjustment block 8 is used to adjust the swing amplitude of the bottle-dispensing block 4; and the bottle dispensing track 5 is used to guide the orderly output of the bottles 3.

[0035] The lower part of the bottle-dispensing block 4 has a slot for adjusting the distance between the head of the bottle-dispensing block 4 and the outer ring of the rotating disk 2 to accommodate bottles 3 of different sizes. The dispensing amplitude adjustment block 8 adopts a slider structure, which adjusts the swing angle of the dispensing arm 9 manually or automatically, thereby controlling the range of motion of the bottle-dispensing block 4.

[0036] The drive motor 11 is a stepper motor or a servo motor, and the rotation speed of the rotating disk 2 is controlled by a frequency converter to achieve precise adjustment of the bottle feeding speed. The surface of the rotating disk 2 is provided with anti-slip texture or rubber coating to increase the friction with the bottle 3 and prevent the bottle 3 from slipping.

[0037] It also includes a sensor system for detecting the number of bottles 3 on the rotating disk 2. When there are fewer bottles 3, the enhanced agitation mode of the bottle-pushing block 4 is automatically activated to prevent the bottles 3 from spinning idly in the center of the disk. The bottle-pushing block 4 is made of an elastic material, such as polyurethane or rubber, to reduce the impact on the bottles 3 and prevent them from breaking.

[0038] The turntable drive shaft 6 and the actuating shaft 10 are fixed by bearing seats to ensure smooth rotation and reduce vibration and noise. The bottle dispensing track 5 is designed with an adjustable width, adapting to different bottle diameters through guide rails and locking devices to ensure smooth output of bottles 3. The entire mechanism is made of stainless steel or aluminum alloy, featuring corrosion resistance and easy cleaning, making it suitable for industries with high hygiene requirements such as food and pharmaceuticals.

[0039] The rotary bottle feeding mechanism of this invention is composed of multiple precision components, each of which is designed based on functional requirements and practicality optimization.

[0040] Bottle Placing Platform 1: Bottle Placing Platform 1 is the entrance section of the mechanism, typically made of stainless steel. Its dimensions can be customized according to production line requirements, for example, 1000mm × 800mm × 200mm (length × width × height). The platform surface is slightly inclined (approximately 5° angle) to facilitate the bottles 3 sliding onto the rotating plate 2 under gravity. Guardrails are provided along the edge of the platform to prevent bottles 3 from falling. The material chosen is 304 stainless steel, which is corrosion-resistant, easy to clean, and meets food hygiene standards. During implementation, Bottle Placing Platform 1 can be bolted to the production line frame to ensure stability.

[0041] Rotary Disk 2: Rotary disk 2 is the core component, a disc-shaped structure with a diameter ranging from 500-1000mm, determined according to the production line capacity. The disk surface is made of aluminum alloy or engineering plastic, making it lightweight and wear-resistant. The disk surface is machined with anti-slip textures (such as a grid-like texture) or coated with a rubber layer to increase friction and prevent bottles 3 from slipping. Rotary disk 2 is connected to drive motor 11 via a turntable drive shaft 6. The drive shaft diameter is typically 30-50mm, made of 45# steel, and heat-treated to enhance its hardness. The rotation speed of rotary disk 2 is adjustable, generally set between 10-30rpm, controlled by a frequency converter to adapt to different production rhythms. During assembly, rotary disk 2 requires dynamic balancing to reduce vibration.

[0042] Bottle 3: This utility model is applicable to various bottles 3, such as plastic bottles and glass bottles, with a bottle diameter range of 50-100mm and a bottle height range of 100-300mm. The mechanism design takes into account the center of gravity and stability of the bottle 3; for example, for tall bottles, the stirring action is gentler. The bottles 3 are arranged in a ring on the rotating disk 2 and are guided to move towards the edge by centrifugal force and the bottle-stirring block 4.

[0043] Bottle-dispensing block 4: Bottle-dispensing block 4 is a key innovative component. It is elongated, 200-300mm long and 50mm wide, made of an elastic material such as polyurethane or rubber with a Shore A hardness of 60-80 to cushion impacts. The lower part of bottle-dispensing block 4 has a slot (10mm wide and 100mm long), which is bolted to the actuating shaft 10, allowing for vertical adjustment to change the distance between the head and the outer ring of the rotating disk 2 (adjustment range 5-20mm). This design allows the mechanism to quickly adapt to different bottle diameters without replacing parts. Bottle-dispensing block 4 is driven by a lever arm 9 to achieve a back-and-forth swing, with the swing frequency synchronized with the rotation speed of the rotating disk 2, typically 1-2Hz.

[0044] Bottle Outlet Track 5: Bottle outlet track 5 is a guide rail structure made of stainless steel plate, with an adjustable width (range 60-110mm) achieved through guide rail sliders and locking bolts. The track outlet connects to subsequent filling equipment. The inner wall of the track is smooth to reduce friction. The track is tilted at an angle of approximately 10°, utilizing gravity to assist in the conveying of bottles 3.

[0045] Turntable drive shaft 6: The drive shaft is the core of the transmission, with a diameter of 40mm and a length determined by the mechanism dimensions, typically 500-800mm. The shaft end is directly connected to the drive motor 11 via a coupling, or via a speed reducer. Ball bearings are used in the bearing housing to ensure smooth rotation. The shaft material is 40Cr steel with a chrome-plated surface for rust prevention.

[0046] Drive gear 7: Drive gear 7 is used to transmit power. It has a module of 2-3 and 20-30 teeth. It is made of 45 steel and hardened. The gear meshes with the turntable drive shaft 6 and the actuation shaft 10 to achieve synchronous transmission. The gear ratio can be designed to be 1:1 or 2:1 to match the actuation frequency.

[0047] Adjustment block 8: The adjustment block is a slider mechanism, for example, using an M8 screw with a length of 100mm. By rotating it, the fulcrum position of the toggle arm 9 is changed, thereby adjusting the swing amplitude (range 10-50mm). The adjustment block can be operated manually or automatically adjusted by adding a stepper motor, facilitating online adjustment.

[0048] Actuating arm 9: The arm is a linkage structure made of aluminum alloy, with a length of 150-200mm. One end is hinged to the actuating shaft 10, and the other end is connected to the actuation amplitude adjustment block 8. The arm converts rotational motion into oscillation. The design takes into account the lever principle to amplify or reduce the amplitude of the movement.

[0049] Actuating shaft 10: The actuating shaft 10 has a diameter of 20mm and is installed parallel to the turntable drive shaft 6, driven by gears. The shaft end is supported on a bearing seat to ensure precise oscillation.

[0050] Drive motor 11: Drive motor 11 is a three-phase asynchronous motor or servo motor with a power of 0.5-1.5kW, equipped with encoder feedback for precise control. The motor is integrated through a PLC (Programmable Logic Controller), allowing for remote parameter adjustment.

[0051] The assembly sequence is as follows: First, fix the bottle placement platform 1 to the base frame; then install the turntable drive shaft 6 and bearing seat, ensuring the shaft is horizontal; next, assemble the turntable 2 and perform a dynamic balance test; then install the drive motor 11 and gear system; finally, assemble the actuating components, including the actuating shaft 10, actuating arm 9, actuating amplitude adjustment block 8, and bottle actuating block 4. During debugging, first run it under no-load to check if the rotation is smooth, then gradually load the bottle 3 and adjust the actuating amplitude and speed. Key debugging points include: the contact force between the bottle actuating block 4 and the bottle 3 should be moderate (tested by a pressure sensor, ideal value 5-10N), avoiding excessive tightness that may cause bottle jamming or excessive looseness that may render it ineffective; the width of the bottle dispensing track 5 must match the bottle diameter, leaving a gap of 1-2mm.

[0052] The working principle and operation process are as follows: During operation, the worker places a tray of bottles 3 on the bottle placement platform 1. The bottles 3 slide towards the rotating disk 2 under gravity or with slight pushing assistance. The drive motor 11 starts, driving the rotating disk drive shaft 6 through the drive gear 7, causing the rotating disk 2 to rotate continuously. The bottles 3 move towards the edge of the rotating disk 2 under the action of centrifugal force. At the same time, the bottle-pushing block 4, driven by the actuation shaft 10 and the swing arm, pushes the bottles 3 back and forth, simulating the action of a human hand, gently pushing the bottles 3 into the bottle exit track 5. When there are few bottles 3, the sensor (such as a photoelectric sensor) detects the accumulation of bottles 3 in the center of the disk, and the signal is transmitted to the PLC, which automatically increases the actuation amplitude or frequency to ensure that the bottles 3 are output smoothly. Throughout the process, the actuation amplitude adjustment block 8 allows for real-time adjustment to adapt to changes in production.

[0053] On one hand, this utility model is used in a beverage bottle production line with a bottle diameter of 75mm, a rotating disk 2 diameter of 800mm, a turning amplitude set to 30mm, a motor speed of 20rpm, and a production speed of 200 bottles / minute. Tests show that the bottle jamming rate is less than 0.1% and the bottle tipping rate is zero.

[0054] On the other hand, this utility model is applicable to small medicine bottles with a diameter of 30mm. By adjusting the four slots of the bottle-shifting block, the spacing can be adjusted to 5mm, and the rotation speed can be reduced to 10rpm to achieve stable delivery.

[0055] Compared with existing technologies, this utility model has significant advantages: Simplified structure: Mechanical linkage reduces electronic components, resulting in a low failure rate. Wide adaptability: The slot and adjustment block design supports rapid model changeover, reducing downtime. Energy saving and environmental protection: The motor has high efficiency and noise levels below 65dB, meeting green manufacturing standards. Economic efficiency: Manufacturing costs are reduced by 30% compared to pneumatic systems, and the maintenance cycle is extended to 6 months.

[0056] The implementation principle of this utility model is as follows: This utility model relates to the field of packaging machinery technology, specifically a rotary bottle feeding mechanism. The mechanism includes a bottle placement platform 1, a rotary disk 2, a bottle outlet track 5, a drive motor 11, a rotary disk drive shaft 6, a drive gear 7, a bottle-feeding block 4, a feeding amplitude adjustment block 8, a feeding swing arm 9, and a feeding shaft 10. The bottle-feeding block 4 simulates a human hand moving the bottle 3 back and forth, preventing the bottle 3 from jamming or tipping over, and the adjustment block allows for flexible adjustment of the feeding amplitude. This utility model solves the problems of easy bottle jamming and tipping in existing fixed spring bottle feeding mechanisms, and has the advantages of simple structure, stable operation, and wide adaptability, making it suitable for automated bottle feeding in bottling production lines.

[0057] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
