Description

Technical Field

[0001] This utility model relates to the field of conveyor belt technology, specifically a folding extension mechanism for conveyor belts. Background Technology

[0002] A transmission belt, also known as a conveyor belt, is the transmission medium in a transmission belt system. A transmission belt system is a type of transmission system that includes two or more pulleys with a transmission belt on them. The pulleys can rotate without restriction to move the transmission belt. One or more of the pulleys are powered to move the transmission belt and carry the material on it. By setting extension structures on the transmission belt, the length of the transmission belt can be extended to meet the needs of conveying different lengths.

[0003] Existing conveyor belt extension structures typically consist of left and right side plates, a synchronous belt, synchronous pulleys, and shafts. They can be made into conveyor belt mechanisms with two or more ends. Each segment of the conveyor belt is an independent loop, and the front and rear segments are connected by shaft collars. The first and last shafts are used independently for the first and last segments of the synchronous belt, while the remaining intermediate shafts serve as common shafts for their corresponding front and rear segments of the synchronous belt. That is, the first segment of the synchronous belt is fitted onto the first and second shafts, the second segment of the synchronous belt is fitted onto the second and third shafts, and so on. The disadvantage is that since the front and rear segments of the conveyor belt are connected in a loop, during assembly or maintenance, it is necessary to assemble and disassemble both the current segment and the adjacent segments simultaneously, which is inconvenient, time-consuming, and labor-intensive. Based on this, a folding extension mechanism for the conveyor belt is proposed to solve the above problems. Utility Model Content

The bottom of the right end of the front right side plate is fixed with a drive wheel shaft, and the outer surface of the drive wheel shaft is fixed with a drive gear.

[0007] Furthermore, the upper surfaces of the left and rear left sides of the side plate, as well as the lower surfaces of the right and rear right sides of the side plate, are all rotatably connected to the same swing block.

[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 The conveyor belt folding extension mechanism in this embodiment includes a front left side plate 1 and a front right side plate 11, and a middle left side plate 5 and a middle right side plate 10 are provided on the right side of the front left side plate 1 and the front right side plate 11.

[0023] In this embodiment, the upper surfaces of the left side 5 and the rear left side 6 of the side plate, as well as the lower surfaces of the right side 10 and the rear right side 8 of the side plate, are all rotatably connected to the same swing block 9.

[0024] The top of the right side of the front left 1 and the front right 11 of the side plate are both provided with grooves, and the top of the left side of the middle left 5 and the middle right 10 of the side plate are both fixed with protrusions. The upper surface of the grooves is provided with threaded grooves, and the upper surface of the protrusions is threaded with a bolt 15 that passes through and extends into the inner cavity of the threaded groove. The bolt 15 is threadedly connected to the threaded groove. When the device needs to be folded, the user first unscrews the bolt 15 out of the inner cavity of the threaded groove, so that the middle left 5 of the side plate is separated from the front left 1 of the side plate and the front right 11 of the side plate and the middle right 10 of the side plate. Then, the rear conveyor belt mechanism is flipped and folded clockwise to achieve the desired result. This can save space required for mechanical transportation to a certain extent, and is highly flexible and easy to disassemble and transport.

[0025] Please see Figures 2 to 4 To avoid complicated disassembly, in this embodiment, the left and right ends of the opposite sides of the front left 1 and front right 11 of the side plate, as well as the middle left 5 and middle right 10 of the side plate, are respectively connected by driven shafts 2 and drive shafts 4 via bearings. The outer surfaces of adjacent driven shafts 2 and drive shafts 4 are provided with the same synchronous belt 3. The right sides of the middle left 5 and middle right 10 of the side plate are provided with the rear left 6 and rear right 8 of the side plate. Multiple conveying shafts 7 are connected by bearings between the opposite sides of the rear left 6 and rear right 8 of the side plate. The left end drive shaft 4 The driven shaft 2 extends through and to the lower side of the front right side plate 11 and the middle right side plate 10 respectively, and the outer surface of both is fixed with driven gears 13. The bottom of the right end of the front right side plate 11 is fixed with a drive wheel shaft 12, and the outer surface of the drive wheel shaft 12 is fixed with a drive gear 14. The drive gear 14 rotates continuously, and the product above the synchronous belt 3 pushes the front product. The product is transported by the front conveyor belt mechanism and the middle conveyor mechanism to the rear conveyor belt mechanism connected by the swing block 9. The conveyor shaft 7 assists in completing the product process and completes the process.

[0026] In this embodiment, multiple pulleys are fixed on the outer surfaces of the driven shaft 2 and the driving shaft 4. The multiple pulleys are evenly distributed on the outer surfaces of the driven shaft 2 and the driving shaft 4. The synchronous belt 3 is connected to the outer surfaces of the two pulleys. Multiple conveying shafts 7 are evenly distributed between the opposite sides of the rear left 6 and the rear right 8 of the side plate. One of the conveying shafts 7 is rotatably connected to the right end between the opposite sides of the middle left 5 and the middle right 10 of the side plate through a bearing.

[0027] It is understandable that when the motor rotates, the motor drives the drive gear 14 to rotate, the rotation of the drive gear 14 drives the driven gear 13 to rotate simultaneously, and the rotation of the driven gear 13 causes the drive shaft 4 fixed in its inner cavity to rotate, thereby causing the pulley on its surface to rotate. The rotation of the pulley further causes the synchronous belt 3 to move, driving the pulley on the surface of the driven shaft 2 and the driven shaft 2 to rotate.

[0028] In addition, the driving gear 14 is meshed with the two driven gears 13.

[0029] It should be noted that a motor is added to the front of the drive wheel shaft 12, which can be used to drive the rotation of the drive wheel shaft 12. The folding effect can be achieved simply by flipping and folding the middle section of the conveyor belt mechanism clockwise, without the need for complicated disassembly.

[0030] It should be noted that in certain specific situations, if the machinery needs to be moved, the middle section of the conveyor belt mechanism can be flipped and folded clockwise. At this time, the front section of the conveyor mechanism will be separated from the middle and rear sections of the conveyor belt mechanism. The middle and rear sections are folded, reducing the space occupied, saving space, and facilitating movement. If a malfunction occurs, flipping and folding the middle section of the conveyor belt mechanism clockwise can shorten the overall length of the machine, making it easier for staff to carry out maintenance, and also facilitating the disassembly and replacement of the synchronous belt 3. During assembly and maintenance, only this section needs to be assembled and disassembled, which greatly simplifies the work.

[0031] The working principle of the above embodiments is as follows:

[0032] In use, when the motor rotates, it drives the drive gear 14 to rotate. The rotation of the drive gear 14 drives the driven gear 13 to rotate simultaneously. In turn, the rotation of the driven gear 13 causes the drive shaft 4, which is fixed in its inner cavity, to rotate. This causes the pulley on its surface to rotate. The rotation of the pulley further causes the synchronous belt 3 to move, driving the pulley on the surface of the driven shaft 2 and the driven shaft 2 to rotate. When the device needs to be folded, the user first unscrews the bolt 15 out of the inner cavity of the threaded groove, so that the left side 5 of the side plate is separated from the front left side 1 and the front right side 11 and the right side 10 of the side plate. Then, the rear conveyor belt mechanism is flipped and folded clockwise to achieve the desired result. To a certain extent, this can save space required for mechanical transportation. It is highly flexible and easy to disassemble and transport. The drive gear 14 rotates continuously, and the product above the synchronous belt 3 pushes the front product. The product is transported through the front conveyor belt mechanism and the middle conveyor mechanism to the rear conveyor belt mechanism connected by the swing block 9. The conveyor shaft 7 assists in completing the product process and the process described above.
