Description

Technical Field

[0001] This utility model relates to the field of flat chain conveyor technology, specifically a flat chain conveyor mechanism. Background Technology

[0002] With the rapid development of industrial automation, flat chain conveyors are being used more and more widely in various industries. Flat chain conveyors are mechanical conveying equipment suitable for conveying items of various shapes and sizes. They can transport not only small items, such as parts, food packaging and medicine bottles, but also heavy goods, such as steel and automobile parts. They have become an indispensable part of modern industry.

[0003] Currently, common flat chain conveyor systems often lack effective protection and limiting structures on both sides when transporting items. Therefore, during high-speed transport or turning sections, items are prone to displacement or collision due to inertia, leading to disordered arrangement or even falling. Secondly, for the transport of precision parts or fragile items, the lack of lateral protection may cause product damage. Furthermore, in automated production lines, deviations in the position of items will affect the accuracy of subsequent robotic gripping or assembly, which not only increases the labor intensity of operators but also reduces transport efficiency and is inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to provide a flat chain conveyor mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flat chain conveyor mechanism, including a positioning frame, and further comprising:

[0006] The flat chain conveyor body is installed inside the positioning frame. A transmission device body that works with the flat chain conveyor body is fixedly connected to one side of the positioning frame. Connecting plates are provided on both the front and rear sides of the top of the positioning frame.

[0007] The fixing frame is fixed to the front and rear sides of the positioning frame. The top of the fixing frame is provided with an adjustment component, which includes a fixing seat, a limiting rod and an extension frame. The connecting plate is equipped with a guardrail.

[0008] Preferably, a support frame is fixed in an array between the bottoms of the two positioning frames, and universal self-locking wheels are installed on the front and rear sides of the bottom of the support frame.

[0009] Preferably, adjustable support legs are provided on both the front and rear sides of the bottom of the support frame, and partitions are fixedly connected to both ends of the guardrail.

[0010] Preferably, the fixing seat is fixed to the top of the fixing frame, the limiting rod is fixed to one side of the connecting plate and its surface is movably connected to the interior of the fixing seat, the extension frame is fixed to the top of the fixing seat, the inner cavity of the extension frame is rotatably connected to a screw, the bottom of the screw is rotatably connected to a toothed plate, and the top of the screw is fixedly connected to a torsion block.

[0011] Preferably, the fixed base has sliding grooves on both sides, and the toothed plate has sliders fixedly connected to both sides of the sliding grooves.

[0012] Preferably, a sliding rod is fixedly connected to one side of the connecting plate, and a limiting plate fixed to the positioning frame is slidably connected to the surface of the sliding rod.

[0013] Preferably, a positioning rod is fixedly connected between the two guardrails, and a guide roller is rotatably connected to the surface of the positioning rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] When the user needs to adjust the two connecting plates and the guardrail to keep the items conveyed on the flat chain conveyor in a straight line, the two torsion blocks can be rotated to raise the toothed plate inside the fixed seat, so that it is disengaged from the inside of the limiting rod. Then, the connecting plates on both sides can be pushed to drive the guardrail and guide roller to move relative to each other, thereby controlling the conveying distance to prevent the conveyed goods from falling and to ensure that subsequent items are picked up smoothly.

[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] Please see Figure 1-4 As shown, a flatbed chain conveyor mechanism includes a positioning frame 1, and further includes:

[0023] The flat chain conveyor body 2 is installed inside the positioning frame 1. A transmission device body 3 that works with the flat chain conveyor body 2 is fixedly connected to one side of the positioning frame 1. Connecting plates 4 are provided on both the front and rear sides of the top of the positioning frame 1.

[0024] Fixed frames 5 are fixed to the front and rear sides of the positioning frame 1. An adjusting component 6 is provided on the top of the fixed frame 5. The adjusting component 6 includes a fixed base 601, a limiting rod 602, and an extension frame 603. A protective railing 7 is installed inside the connecting plate 4. The positioning frame 1 facilitates the positioning and installation of the flat chain conveyor body 2. The transmission device body 3 contains components such as a motor drive belt, which work in conjunction with the flat chain conveyor body 2 for transmission drive. The principle is as follows: Motor start-up: The motor is typically a three-phase asynchronous motor or a servo motor providing power. A reducer is connected via a coupling. Speed ​​reduction and torque increase: The reducer reduces the speed and increases the output torque. The torque is adapted to the driving force required by the chain. The sprocket drive: the output shaft of the reducer drives the active sprocket to rotate. Through the meshing of the sprocket teeth with the chain, the flat chain is pulled to move. The driven wheel guide: the driven sprocket or roller group at the other end of the chain provides tension and direction, forming a closed loop. This is the prior art, which can be clearly understood by those skilled in the art, and will not be described in detail here. The fixing frame 5 facilitates the support and fixing of the adjusting component 6, and the adjusting component 6 facilitates the adjustment of the spacing of the conveyed items. The guardrail 7 and the connecting plate 4 can prevent items from falling from both sides of the flat chain conveyor body 2 during high-speed conveying.

[0025] A support frame 8 is fixedly arranged between the bottoms of two positioning frames 1. Universal self-locking wheels 9 are installed on the front and rear sides of the bottom of the support frame 8. Adjustable support legs 10 are provided on the front and rear sides of the bottom of the support frame 8. Partition plates 11 are fixedly connected to both ends of the guardrail 7. A positioning rod 12 is fixedly connected between the two guardrails 7. A guide roller 13 is rotatably connected to the surface of the positioning rod 12. A sliding rod 14 is fixedly connected to one side of the connecting plate 4. A limiting plate 15, fixed to the positioning frame 1, is slidably connected to the surface of the sliding rod 14. The support frame 8 facilitates the support of the positioning frame 1, while the universal self-locking wheels 9 facilitate the movement of the support frame 8 to the required position. Adjustable support legs 10... The height between the support frame 8 and the ground can be adjusted by rotating the internal threads and threaded rods of the support leg 10. This is existing technology and is clearly known to those skilled in the art, so it will not be described in detail here. The partition 11 can limit the two ends of the flat chain conveyor body 2, while ensuring the strength of the installation between the two guardrails 7. The positioning rod 12 facilitates the installation of the guide roller 13, which can assist in limiting and guiding the conveying of items. The slide rod 14 is fixed to the connecting plate 4. When the connecting plate 4 moves, it will drive the slide rod 14 to move within the limiting plate 15, thereby improving the stability of the connecting plate 4 when it moves.

[0026] The fixed base 601 is fixed to the top of the fixed frame 5. The limiting rod 602 is fixed to one side of the connecting plate 4, and its surface is movably connected to the interior of the fixed base 601. The extension frame 603 is fixed to the top of the fixed base 601. A screw 604 is rotatably connected to the inner cavity of the extension frame 603. A toothed plate 605 is rotatably connected to the bottom of the screw 604. A torsion block 606 is fixedly connected to the top of the screw 604. Slide grooves 607 are provided on both sides of the interior of the fixed base 601. Sliding blocks 608 that slide in the slide grooves 607 are fixedly connected to both sides of the toothed plate 605. First, when the user needs to adjust the two connecting plates 4 to... When adjusting the movable spacing of the conveyor at the top of the flat chain conveyor body 2, the torsion block 606 is rotated to make the screw 604 rotate. At this time, the screw 604 rotates and drives the toothed plate 605 to rise. When the toothed plate 605 moves, it drives the slider 608 to move within the slide groove 607. Then, the user can push the limit rod 602 to move the connecting plate 4 to one side, and then rotate the torsion block 606 in the opposite direction to finally make the toothed plate 605 lock into the top of the limit rod 602 again, thereby limiting the adjusted position. The same operation is performed on the other side to complete the adjustment.

[0027] Working principle: First, place the transported items on the flat chain conveyor body 2. Then, when the user needs to adjust the two connecting plates 4 and the guardrail 7 to adjust the movable spacing of the conveyor at the top of the flat chain conveyor body 2, rotate the torsion block 606 to rotate the screw 604. At this time, the screw 604 will rotate and drive the toothed plate 605 to rise. When the toothed plate 605 moves, it will drive the slider 608 to move within the slide groove 607. Then, the user can push the limit rod 602 to drive the connecting plate 4 to move to one side. When the connecting plate 4 moves, it will drive the guardrail 7 and the partition 11 to move. When the connecting plate 4 moves, it will also drive the slide rod 14 to move within the limit plate 15, thereby improving the stability during movement. Then, rotate the torsion block 606 in the opposite direction to finally make the toothed plate 605 lock onto the top of the limit rod 602 again, thereby limiting the adjusted position. The same operation is performed on the other side to complete the adjustment.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
