Description

[0001] This utility model belongs to the technical field of double-speed chain conveyor equipment, specifically relating to a pallet limiting mechanism for pallet conveying in a double-speed chain conveyor. Background Technology

[0002] With the continuous improvement of industrial automation, the application scenarios of high-speed chain conveyor lines are becoming increasingly complex, and the requirements for the accuracy and stability of pallet conveying are also increasing. Currently, most pallet conveyor devices on the market use fixed limiting structures, which cannot be flexibly adjusted according to the size, weight, and characteristics of the pallets being conveyed. For example, when conveying pallets of different specifications, fixed limiting structures are difficult to adapt, requiring the replacement of the entire limiting assembly, which is cumbersome and increases production costs. Furthermore, some limiting mechanisms can only limit the sides of the pallet, lacking support and limiting at the bottom, causing the pallet to sway up and down during high-speed conveying, affecting the stable placement of products. Furthermore, some existing limiting mechanisms use rigid limiting methods, which easily generate large impact forces when the pallet contacts the limiting components. This not only causes wear and tear on the pallet and limiting components, shortening the equipment's lifespan, but may also cause vibration affecting the products on the pallet, leading to positional displacement or damage. Additionally, the power transmission components of traditional limiting mechanisms are poorly designed, prone to insufficient power or unstable transmission when driving the pallet, further affecting the stability of pallet conveying. In summary, existing pallet limiting mechanisms for double-speed chain conveyor lines suffer from problems such as inconvenient adjustment, poor limiting effect, susceptibility to impact damage, and unstable power transmission, failing to meet the demands of modern industrial production for efficient, stable, and flexible pallet conveying. Therefore, we propose a pallet limiting mechanism for double-speed chain conveyor lines to solve these problems. Summary of the Invention

[0003] The purpose of this utility model is to provide a pallet limiting mechanism for pallet conveying in a high-speed chain production line, so as to solve the problems mentioned in the background art, such as inconvenient adjustment, poor limiting effect, easy impact damage and unstable power transmission of existing pallet limiting mechanisms.

[0004] The specific technical solution adopted by this utility model is as follows: A pallet limiting mechanism for pallet conveying in a high-speed chain conveyor includes two symmetrically arranged first limiting rods, a plurality of second limiting rods between the two first limiting rods, and the two ends of the plurality of second limiting rods are respectively fixedly connected to the side walls of the two first limiting rods. The two first limiting rods and the plurality of second limiting rods are arranged perpendicularly. A plurality of power components are provided on the opposite side wall of the two first limiting rods. A mounting plate is fixedly connected to each of the two first limiting rods. A plurality of adjustable limiting components are provided on each of the two mounting plates, and a third limiting rod is provided at the end of each of the plurality of adjustable limiting components away from the first limiting rod.

[0005] In a preferred embodiment, the power assembly includes a mounting base on which an electric rotary rod is fixedly mounted, and the output end of the electric rotary rod is connected to a guide wheel.

[0006] In a preferred embodiment, the adjustable limiting component includes a first assembly block, a plurality of second assembly blocks, and a third assembly block. The bottom of the first assembly block and the plurality of second assembly blocks are fixedly connected to a connecting block, and the plurality of second assembly blocks and the third assembly blocks are provided with a first slot that matches the connecting block. The plurality of second assembly blocks and the third assembly blocks are each inserted with a first fixing rod that matches the connecting block. The side walls of the plurality of second assembly blocks and the third assembly blocks are each provided with a first buckle that matches the first fixing rod.

[0007] In a preferred embodiment, the first assembly block is provided with a second slot, and a first adjusting rod is inserted into the second slot. The first adjusting rod has a hollow structure, and a second adjusting rod is inserted into the first adjusting rod. A manual rotating rod is inserted into the first adjusting rod, and a gear is sleeved on the manual rotating rod. The side wall of the second adjusting rod is provided with a toothed groove that meshes with the gear. A slider is fixedly connected to the bottom wall of the second adjusting rod, and the slider is connected to the bottom wall of the first adjusting rod through a buffer spring. A second buckle that matches the manual rotating rod is provided on the side wall of the first adjusting rod.

[0008] In a preferred embodiment, a horizontally positioned limiting plate is fixedly connected to the second adjusting rod, and two symmetrically positioned mounting rods are inserted into the limiting plate. Each of the two mounting rods is engaged with a horizontally positioned second fixing rod, and the second fixing rod is matched with the third limiting rod.

[0009] In a preferred embodiment, a bottom support rod is engaged with each of the multiple second limiting rods, and all the bottom support rods are vertically arranged.

[0010] The technical effects achieved by this utility model are as follows: By incorporating an adjustable limiting component and employing an assembly structure consisting of a first, second, and third assembly block, the height of the limiting mechanism can be flexibly adjusted. Simultaneously, utilizing the gear meshing transmission structure of the first and second adjusting rods, the horizontal length of the limiting mechanism can be precisely adjusted, enabling adaptation to pallets of different specifications. This solves the problem of inconvenient adjustment in existing limiting mechanisms and greatly improves the mechanism's versatility. The mechanism also features a third limiting rod for side limiting and a bottom supporting rod. The third limiting rod, through the adjustable limiting component, can precisely contact the side of the pallet, while the bottom supporting rod supports the bottom of the pallet, forming a comprehensive limiting structure. This effectively prevents pallet shifting or swaying during transport, significantly improving pallet transport stability and ensuring safe product delivery. A buffer spring is incorporated into the adjustable limit assembly, which acts as a buffer when the second adjusting rod moves and when the tray contacts the third limit rod, reducing the impact force on the tray and limit components, extending the service life of the equipment, and preventing damage or displacement of products on the tray due to vibration. The power unit adopts an electric rotary rod to drive the guide wheel. The guide wheel makes rolling contact with the pallet, which not only provides stable power for pallet transportation, but also reduces friction and wear between components, ensuring smooth pallet transportation and solving the problems of insufficient power or unstable transmission in traditional power transmission components. The mechanism employs detachable connection methods such as snap-fit ​​and plug-in for multiple components, such as the snap-fit ​​between the bottom support rod and the second limit rod, and the snap-fit ​​between the third limit rod and the second fixing rod. This facilitates the disassembly, replacement, and maintenance of components, reduces the maintenance cost and difficulty of the equipment, and improves the ease of use of the equipment.

Detailed Implementation

[0013] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0014] Please see Figure 1-4 As shown, this utility model provides a pallet limiting mechanism for pallet conveying in a high-speed chain conveyor system. It includes two symmetrically arranged first limiting rods 1, and a plurality of second limiting rods 2 are provided between the two first limiting rods 1. The two ends of the plurality of second limiting rods 2 are respectively fixedly connected to the side walls of the two first limiting rods 1. The two first limiting rods 1 and the plurality of second limiting rods 2 are arranged perpendicularly. A plurality of power components are provided on the opposite side walls of the two first limiting rods 1. A mounting plate 3 is fixedly connected to each of the two first limiting rods 1. A plurality of adjustable limiting components are provided on each of the two mounting plates 3. A third limiting rod 4 is provided at the end of the plurality of adjustable limiting components away from the first limiting rods 1. The power assembly includes a mounting base 5, on which an electric rotating rod 6 is fixedly mounted. The output end of the electric rotating rod 6 is connected to a guide wheel 7. The electric rotating rod 6 is stably mounted on the first limit rod 1 via the mounting base 5. When the electric rotating rod 6 is working, it can drive the guide wheel 7 to rotate. After the guide wheel 7 contacts the pallet, it can provide stable power for pallet conveying. At the same time, the rolling contact method of the guide wheel 7 can reduce friction between it and the pallet, reduce component wear, and ensure smooth pallet conveying. The adjustable limiting component includes a first assembly block 8, multiple second assembly blocks 9, and a third assembly block 10. The bottom of the first assembly block 8 and the multiple second assembly blocks 9 are all fixedly connected to a connecting block 11, and the multiple second assembly blocks 9 and the third assembly blocks 10 are all provided with a first slot that matches the connecting block 11. The multiple second assembly blocks 9 and the third assembly blocks 10 are all provided with a first fixing rod 12, and the first fixing rod 12 matches the connecting block 11. The side walls of the multiple second assembly blocks 9 and the third assembly blocks 10 are all provided with a first buckle 13 that matches the first fixing rod 12. The first assembly block 8 is initially connected to the second assembly block 9 through the first slot of the connecting block 11. The number of second assembly blocks 9 can be increased or decreased according to the actual limiting height requirements. Then, the assembly is completed by the third assembly block 10. After the first fixing rod 12 is inserted, it can fix the connecting block 11 to prevent the assembled components from loosening. The first buckle 13 can limit the first fixing rod 12 to prevent it from falling off during use. Through this assembly structure, the overall height of the adjustable limiting component can be flexibly adjusted to adapt to pallets of different height specifications. The first assembly block 8 has a second slot, and a first adjusting rod 14 is inserted into the second slot. The first adjusting rod 14 is hollow, and a second adjusting rod 15 is inserted into the first adjusting rod 14. A manual rotating rod 16 is inserted into the first adjusting rod 14, and a gear 17 is fitted onto the manual rotating rod 16. The side wall of the second adjusting rod 15 has a toothed groove that meshes with the gear 17. A slider 18 is fixedly connected to the bottom wall of the second adjusting rod 15, and the slider 18 is connected to the bottom wall of the first adjusting rod 14 through a buffer spring 19. The side wall of the first adjusting rod 14 has a second buckle 20 that matches the manual rotating rod 16. The first adjusting rod 14 is connected to the first assembly block 8 through the second slot. When the manual rotating rod 16 is rotated, the gear 17 rotates accordingly. Since the gear 17 meshes with the toothed groove on the second adjusting rod 15, it can drive the second adjusting rod 15 to move up and down within the first adjusting rod 14, thereby adjusting the horizontal length of the adjustable limiting component to adapt to pallets of different widths. The slider 18 and the buffer spring 19 can buffer the movement of the second adjusting rod 15, reducing the impact force during adjustment. At the same time, when the tray contacts the third limiting rod 4, it can buffer the pressure brought by the tray and avoid damage caused by rigid collision. The second buckle 20 can fix the manual rotating rod 16 to prevent it from rotating on its own during use and ensure the stability of the adjusted length. A horizontally positioned limiting plate 21 is fixedly connected to the second adjusting rod 15. Two symmetrically arranged mounting rods 22 are inserted into the limiting plate 21, and each mounting rod 22 is engaged with a horizontally positioned second fixing rod 23. The second fixing rod 23 is matched with the third limiting rod 4. The limiting plate 21 provides the mounting base for the mounting rods 22. By adjusting the insertion position of the mounting rods 22 on the limiting plate 21, the installation position of the second fixing rod 23 can be changed, thereby adjusting the installation angle and position of the third limiting rod 4. This allows the third limiting rod 4 to make more precise contact with the pallet, achieving effective limiting of the pallet. The engaging fit between the second fixing rod 23 and the third limiting rod 4 facilitates the disassembly and replacement of the third limiting rod 4. When the third limiting rod 4 becomes worn, it can be quickly replaced, reducing maintenance costs. Each of the multiple second limiting rods 2 is engaged with a bottom support rod 24, and all the bottom support rods 24 are vertically arranged. The bottom support rods 24 can support and limit the bottom of the pallet, preventing the pallet from swaying up and down during transportation, and further improving the stability of pallet transportation; the engagement method between the bottom support rods 24 and the second limiting rods 2 makes it easy to adjust the installation position and number of the bottom support rods 24 according to the bottom structure and size of the pallet, thus improving the adaptability of the mechanism.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
