Description

Technical Field

[0001] The utility model relates to the field of mold sandblasting, in particular to a buffer guide device for a turning conveyor belt. Background Art

[0002] Sandblasting machines are widely used in the surface treatment of molds because the impact and cutting effect of abrasives on the surface of the workpiece can make the surface of the workpiece obtain a certain degree of cleanliness and different roughness, and improve the mechanical properties of the workpiece surface. After the mold is sandblasted, it will be transported by a conveyor. Due to the size limitation of the site, the conveyor includes a turning conveyor belt and a straight conveyor belt connected to the turning conveyor belt. Since the mold will generate inertia when it is transported to the turning conveyor belt, the mold will be subjected to a lateral force. This force will push the mold to the connection between the turning conveyor belt and the straight conveyor belt. Since the turning conveyor belt and the straight conveyor belt have different sizes at the connection, the mold is easily stuck at the connection between the turning conveyor belt and the straight conveyor belt.

[0003] In order to avoid the situation where the mold is stuck, the existing technology will set a guide part at the discharge end of the curved conveyor belt to guide the mold to the straight conveyor belt. Due to the inertia of the mold, when it contacts the guide part, it will generate a relatively large impact force, causing the guide part to be easily damaged. Damage to the guide part will make it unable to effectively guide the mold, causing the mold to deviate from the correct path during transportation, and even cause blockage or shutdown of the conveying device. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, the present invention provides a buffering guide device for a turning conveyor belt, which aims to solve the technical problem that due to the inertia of the mold, when it contacts the guide part, a relatively large impact force will be generated, causing the guide part to be easily damaged.

[0032] Reference Figures 1-6 In some specific embodiments, a buffer guide device for a turning conveyor belt includes a conveyor frame 1, a conveyor belt 2 is provided on the top of the conveyor frame 1, a guide portion 3 is provided on the top of the conveyor frame 1, a discharge end 36 is provided at one end of the conveyor belt 2, and the guide portion 3 is close to the discharge end 36 of the conveyor belt 2. A mounting seat 15 is provided on the top of the conveyor frame 1, one side of the mounting seat 15 extends to above the discharge end 36, a movable cavity 16 is opened on one side of the mounting seat 15, a buffer spring 18 is provided inside the movable cavity 16, and a connecting seat 26 is provided at one end of the buffer spring 18. The connecting seat 26 slides with the inside of the movable cavity 16 so that one side of the connecting seat 26 protrudes from the outside of the movable cavity 16, and the guide portion 3 is installed on one side of the connecting seat 26.

[0033] Through the above technical solution, when the mold collides with the guide part 3, the connecting seat 26 can slide in the movable cavity 16, and the force is transmitted to the buffer spring 18 through the connecting seat 26. The buffer spring 18 is compressed and absorbs most of the impact force, which not only protects the guide part 3, but also reduces the damage to the mold surface.

[0034] Reference Figure 4-Figure 6 In some specific embodiments, a movable seat 17 is provided at one end of the buffer spring 18, and a mounting slot 19 is provided at one end of the movable seat 17. A mounting plug 28 is provided on the other side of the connecting seat 26. The mounting plug 28 is plugged into the mounting slot 19. A first fixing hole 24 is provided on the outside of the movable seat 17. The first fixing hole 24 is connected to the mounting slot 19. A second fixing hole 29 is provided on the outside of the mounting plug 28. A fixing bolt 25 is passed through the first fixing hole 24, and the inserted end of the fixing bolt 25 is threadedly engaged with the second fixing hole 29.

[0035] Through the above technical solution, the stability of the connection is further enhanced by the fixing bolt 25 passing through the first fixing hole 24 and threadedly engaging with the second fixing hole 29. When it is necessary to replace or repair the guide part 3 and other components, it is only necessary to remove the fixing bolt 25 to easily separate the connecting seat 26 and the movable seat 17, so that the connection between the connecting seat 26 and the movable seat 17 is both firm and detachable.

[0036] In addition, the mounting slot 19 of the movable seat 17 can be designed to be circular, rectangular or other polygonal cross-sections to accommodate mounting plugs 28 of different shapes. The depth of the mounting slot 19 can be designed according to actual needs, usually 20-50 mm. The shape of the mounting plug 28 on the connecting seat 26 matches the mounting slot 19, and an interference fit or a clearance fit can be used, depending on the required connection strength and ease of disassembly.

[0037] Reference Figure 4-Figure 6 In some specific embodiments, guide grooves 33 are provided on both sides of the movable cavity 16, and first guide blocks 34 are provided on both sides of the movable seat 17. The first guide blocks 34 on both sides of the movable seat 17 slide with the guide grooves 33 on both sides of the movable cavity 16 respectively, and second guide blocks 35 are provided on both sides of the connecting seat 26. The second guide blocks 35 on both sides of the connecting seat 26 slide with the guide grooves 33 on both sides of the movable cavity 16 respectively.

[0038] Through the above technical solution, by arranging guide grooves 33 on both sides of the movable cavity 16, and arranging first guide blocks 34 and second guide blocks 35 that slide with the movable seat 17 and the connecting seat 26 on both sides thereof, precise guidance of the movement of the movable seat 17 and the connecting seat 26 can be achieved. This design not only ensures that the movable seat 17 and the connecting seat 26 move along a predetermined track when compressing and releasing the buffer spring 18, but also reduces friction and wear, thereby extending the service life of the device.

[0039] The guide slot 33 can be designed in a variety of shapes, such as rectangular, dovetail, or T-shaped. These shapes can be selected based on specific application requirements and load capacity. Rectangular slots are simple and easy to manufacture; dovetail slots offer enhanced self-locking properties, preventing the guide block from disengaging; and T-shaped slots offer both good guidance and load capacity. The guide slot 33 is typically designed to be 5-20mm deep and 10-30mm wide. This range ensures smooth sliding of the first and second guide blocks 34, 35 while providing sufficient support.

[0040] Reference Figures 1-6 In some specific embodiments, a first mounting post 20 is provided inside the movable cavity 16, and the first mounting post 20 is plugged into the other end of the buffer spring 18. A second mounting post 22 is provided at the other end of the movable seat 17, and the second mounting post 22 is plugged into one end of the buffer spring 18.

[0041] Through the above technical solution, a first mounting column 20 is set inside the movable cavity 16 and is plugged into one end of the buffer spring 18. At the same time, a second mounting column 22 is set at the other end of the movable seat 17 and is plugged into the other end of the buffer spring 18, thereby fixing the two ends of the buffer spring 18. This design can effectively prevent the buffer spring 18 from being displaced or falling off during operation, thereby improving the stability and reliability of the device.

[0042] Reference Figures 1-6 In some specific embodiments, first mounting protrusions 21 are provided on both sides of the first mounting column 20, and the first mounting protrusions 21 on both sides of the first mounting column 20 are internally engaged with the other end of the buffer spring 18, and second mounting protrusions 23 are provided on both sides of the second mounting column 22, and the second mounting protrusions 23 on both sides of the second mounting column 22 are internally engaged with one end of the buffer spring 18.

[0043] Through the above technical solution, the first mounting protrusion 21 and the second mounting protrusion 23 are respectively engaged with the internal ends of the buffer spring 18, which increases the contact area and friction force, and improves the stability of the connection; the engaging structure can prevent the buffer spring 18 from axial movement or falling off during compression and release, ensuring the stable position of the buffer spring 18; and the first mounting protrusion 21 and the second mounting protrusion 23 can prevent the buffer spring 18 from rotating, further enhancing the reliability of the connection.

[0044] Reference Figure 2-Figure 6 In some specific embodiments, the guide portion 3 includes multiple guide shafts 32 and multiple guide rollers 31. A rotating cavity 27 is opened on one side of the connecting seat 26. The two ends of the multiple guide shafts 32 are rotatably connected to the two sides of the rotating cavity 27. The multiple guide rollers 31 are respectively mounted outside the multiple guide shafts 32.

[0045] Through the above technical solution, when the mold is output from the discharge end 36 of the turning conveyor belt 2, it will first contact the guide roller 31. Since the guide roller 31 can rotate freely, they will rotate with the movement of the mold, greatly reducing the friction between the mold and the guide part 3. This not only reduces the risk of the mold surface being scratched or damaged, but also effectively reduces the movement resistance of the mold, allowing the mold to pass through the turn more smoothly.

[0046] Reference Figure 1-Figure 3In some specific embodiments, a support rod 4 is provided on the top of the conveying frame 1, and a lifting frame 6 is provided on the outside of the support rod 4. A lifting cavity 7 is opened inside the lifting frame 6, and the lifting cavity 7 is sleeved on the outside of the support rod 4. The lifting cavity 7 and the support rod 4 are slidably matched. The mounting seat 15 is installed on one side of the lifting frame 6, and a first adjustment hole 9 is opened on the other side of the lifting frame 6. The first adjustment hole 9 is connected to the lifting cavity 7. The first adjustment hole 9 is internally threaded with a first adjusting bolt 8, and the first adjusting bolt 8 conflicts with the support rod 4.

[0047] Through the above technical solution, the lifting cavity 7 inside the lifting frame 6 slides with the support rod 4, so that the lifting frame 6 can move up and down on the support rod 4, and the mounting seat 15 is installed on one side of the lifting frame 6, so that the height of the guide part 3 can change with the movement of the lifting frame 6. By rotating the first adjusting bolt 8, it can be made to contact with the support rod 4, thereby fixing the lifting frame 6 at the desired height to adapt to molds of different models and sizes.

[0048] Reference Figure 1-Figure 3 In some specific embodiments, a limiting plate 5 is provided on the top of the support rod 4 , and the limiting plate 5 is located above the lifting frame 6 .

[0049] Through the above technical solution, when the lifting frame 6 moves upward along the support rod 4, the limit plate 5 will block the lifting frame 6 from continuing to rise, thereby preventing the lifting frame 6 from completely separating from the support rod 4, thereby improving the safety and reliability of the device.

[0050] Reference Figure 1-Figure 3 In some specific embodiments, an adjustment seat 10 is provided on one side of the lifting frame 6 , the top of the adjustment seat 10 is rotatably connected to a movable arm 12 , and the mounting seat 15 is connected to the movable arm 12 .

[0051] Through the above technical solution, the adjustment seat 10 serves as a fixed base, providing a stable support point for the movable arm 12. The rotational connection between the movable arm 12 and the adjustment seat 10 enables the movable arm 12 to rotate freely within a certain angle range. The connection between the mounting seat 15 and the movable arm 12 enables the entire guide part 3 to change its angle as the movable arm 12 rotates, so as to facilitate adjusting the direction of the guide part 3.

[0052] Reference Figure 1-Figure 3 In some specific embodiments, a plurality of second adjustment holes 11 are provided on the top of the adjustment seat 10, a third adjustment hole 13 is opened inside the movable arm 12, a second adjustment bolt 14 is passed through the third adjustment hole 13, and the second adjustment bolt 14 is threadedly engaged with any second adjustment hole 11.

[0053] Through the above technical solution, when the angle of the guide part 3 needs to be adjusted, the operator can first loosen the second adjusting bolt 14, and then rotate the movable arm 12 to a suitable angle as needed. Then, the second adjusting bolt 14 is passed through the third adjusting hole 13, and a suitable second adjusting hole 11 is selected for threaded connection. Finally, the second adjusting bolt 14 is tightened to fix the angle of the movable arm 12. This adjustment method is simple and intuitive, and greatly improves the efficiency of adjustment.
