[0003] In the prior art, after the driving device of some heavy-duty reciprocating synchronous belt automatic loading and unloading conveying mechanisms is started, the load table makes reciprocating movements in the horizontal direction to achieve horizontal conveying of materials.

However, in the specific use process, under heavy-duty conditions, the synchronous belt conveying mechanism may cause vibration and deviation during the transmission due to uneven load distribution or insufficient synchronous belt tension, affecting the transmission accuracy. Therefore, in response to the above problems, a heavy-duty reciprocating synchronous belt automatic loading and unloading conveying mechanism is proposed. Summary of the Utility Model

The bench main body 1 is made of high-strength steel and has sufficient rigidity and stability to support the operation of the entire conveying mechanism. On the left side inside the bench main body 1, there is a fixed connection with a driving component for providing rotational force. The driving component includes a reduction motor 2. The reduction motor 2 is fixed to the left side inside the bench main body 1 by bolts to ensure that it stably and reliably provides rotational force. The outside of the driving wheel 3 is fixedly connected to the driving end of the reduction motor 2. The outside of the reduction motor 2 is fixedly connected inside the bench main body 1. The outside of the driving component is rotatably connected with a driving wheel 3.

The synchronous belt 4 is made of wear-resistant rubber material and has good wear resistance and tensile strength;

[0033] On the left side outside the bench main body 1, there is a rotatable connection with a driven wheel 5. The driven wheel 5 is installed on the left side outside the bench main body 1 through a bearing and jointly supports the movement of the synchronous belt 4 with the driving wheel 3. On the front and rear sides of the top of the bench main body 1, there are fixed connections with slide rails 6. The slide rails 6 adopt a linear guide rail structure and are installed on the front and rear sides of the top of the bench main body 1 to provide a smooth sliding path for the slider 7. The outside of the slide rail 6 is slidably connected with a slider 7. The slider 7 is connected to the bench main body 1 through the slide rail 6 and can slide freely on the slide rail 6. On the top of the slider 7, there is a fixed connection with a moving carrier plate 8. The moving carrier plate 8 is fixed to the top of the slider 7 by bolts and forms an integral movement with the slider 7. On the front and rear sides of the top of the moving carrier plate 8, there are fixed connections with positioning columns 9. The positioning columns 9 are used to position the moving carrier plate 8 to ensure its stable position during movement. At the four corners outside the moving carrier plate 8, there are fixed connections with fastening plates 10. The fastening plates 10 are fixed to the four corners outside the moving carrier plate 8 by bolts to increase the stability and load-bearing capacity of the moving carrier plate 8;

[0034] Refer to Figures 3 to 5 , on the right side outside the bench main body 1, there is a fixed connection with a button box 11. The button box 11 is made of waterproof plastic material and has multiple control buttons inside, which is convenient for operators to control the equipment. On the front side outside the bench main body 1, there is a fixed connection with a wire distribution box 12. The wire distribution box 12 is used for centralized management and protection of electrical circuits to ensure the normal operation of the equipment. At the four corners outside the bench main body 1, there are fixed connections with support frames 13. The support frames 13 are made of high-strength steel and have sufficient rigidity and stability to support the installation of the photoelectric sensor 14. On the top of the support frame 13, there is a fixed connection with a photoelectric sensor 14. The photoelectric sensor 14 is used to detect the position of the moving carrier plate 8 to achieve the automatic loading and unloading function. On the left side outside the bench main body 1, there is a fixed connection with a proximity switch 15. The proximity switch 15 is used to detect whether the moving carrier plate 8 reaches the specified position and provide a signal to the control system;

[0035] On both inner sides of the bench main body 1, cylinders 16 are fixedly connected. The cylinders 16 are made of aluminum alloy material, featuring light weight, high strength, and corrosion resistance. An ejecting device 17 is fixedly connected to the outside of the cylinder 16. The ejecting device 17 is used to push materials or workpieces out of the moving carrier plate 8 to achieve the function of automatic blanking. The driving end of the cylinder 16 is fixedly connected with an ejecting connecting rod 18. The ejecting connecting rod 18 is connected to the cylinder 16 through threads to achieve reliable transmission. A plurality of bench shields 19 are fixedly connected to the top of the bench main body 1. The bench shields 19 are made of transparent acrylic plates, playing a role in protection and aesthetics. Limit blocks 20 are fixedly connected to the four corners of the outside of the bench main body 1. The limit blocks 20 are made of wear-resistant rubber material and are used to limit the movement range of the slide rail 6 to ensure the safe operation of the equipment. The outside of the limit block 20 is fixedly connected to the left and right sides of the outside of the slide rail 6. The outside of the moving carrier plate 8 is slidably connected to the outside of the bench main body 1 and can freely slide on the slide rail 6. The outside of the driving wheel 3 and the outside of the driven wheel 5 are coupled and connected, and stable transmission is achieved through the synchronous belt 4. The outside of the driving wheel 3 and the outside of the driven wheel 5 are coupled and connected.

[0036] Working principle: When starting, the reduction motor 2 provides rotational power and drives the movement of the synchronous belt 4 through the driving wheel 3. The synchronous belt 4 connects the driving wheel 3 and the driven wheel 5 to form a stable power transmission system. As the driving wheel 3 rotates, the driven wheel 5 also rotates, driving the synchronous belt 4 to move forward. The moving carrier plate 8 is fixed to the top of the slider 7. The slider 7 freely slides on the top of the bench main body 1 through the slide rail 6. As the synchronous belt 4 moves, the slider 7 moves smoothly on the slide rail 6, thereby causing the moving carrier plate 8 to move accordingly. The positioning column 9 ensures that the moving carrier plate 8 maintains a stable position during movement, and the fastening plate 10 further enhances the stability and load-bearing capacity of the moving carrier plate 8.

[0037] Place the workpiece on the moving chassis and fix it with the positioning column 9. When the photoelectric sensor 14 detects that a workpiece is placed on the moving carrier plate 8, the ejecting device 17 retracts. The moving carrier plate 8 is connected to the bench main body 1 through the slide rail 6 and the slider 7. The slide rail 6 and the slider 7 serve as a guiding device. The reduction motor 2 starts and drives the driving wheel 3 to rotate through the synchronous belt 4. As a result, the synchronous belt 4 between the driving wheel 3 and the driven wheel 5 also moves linearly. Since the moving carrier plate 8 is fixed to the synchronous belt 4 through the connecting plate, when the synchronous belt 4 moves linearly, it will drive the moving carrier plate 8 to move together. When the bottom plate moves to the other end, the proximity switch 15 conducts in-place detection and decelerates the bottom plate. The limit block 20 buffers the speed of the moving carrier plate 8. At this time, the ejecting device 17 presses the moving carrier plate 8 against the limit block 20 and waits for the workpiece to be blanked. After the workpiece blanking is completed, the ejecting device 17 retracts, the reduction motor 2 rotates in the reverse direction, and the synchronous belt 4 runs in the reverse direction to perform the next loading. The base reciprocates with a positioning accuracy of ±0.05 mm.

[0038] During the movement, the photoelectric sensor 14 detects the position of the moving carrier plate 8 to ensure that it can accurately reach the specified position during the loading and unloading process. At the same time, the proximity switch 15 monitors whether the moving carrier plate 8 reaches the preset loading and unloading positions, providing signals to the control system to achieve automatic control. When the moving carrier plate 8 reaches the unloading position, the cylinder 16 is activated, and the pushing device 17 pushes the material or workpiece off the moving carrier plate 8 through the pushing link 18, realizing the automatic unloading function. The lightweight and high-strength characteristics of the cylinder 16 ensure the effectiveness and reliability of the pushing device 17.

[0039] During the whole process, the gantry shield 19 provides protection to ensure operation safety. At the same time, the limit block 20 restricts the movement range of the slide rail 6, further ensuring the safe operation of the equipment. Through this series of coordinated actions, the heavy-duty reciprocating synchronous belt 4 automatic loading and unloading conveying mechanism efficiently completes the automatic loading and unloading tasks of materials.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
