Description

Technical Field

[0001] This utility model belongs to the field of curve machine technology, specifically relating to a folding plate guardrail for curve machines. Background Technology

[0002] A curved roller conveyor is a piece of equipment used in the industrial field. It uses conical rollers as a carrier and can smoothly transport items along a curved track.

[0003] Domestic utility model patent application number 202021555234.X discloses a packaging box conveyor curve and its guardrail device, belonging to the technical field of tobacco production equipment. It mainly includes a frame, an inlet conveyor belt, a middle conveyor belt, an outlet conveyor belt, a left guardrail, and a right guardrail. The inlet, middle, and outlet conveyor belts are sequentially connected and installed on the frame. Each conveyor belt is driven by its own independent conveyor motor. The left and right guardrails are matched and installed on the frame, forming a conveying channel. This utility model ensures smooth conveying of packaged boxes in the curve channel, preventing boxes from falling out. The width of the conveying channel is adjustable, making operation convenient and preventing box blockage, thus ensuring smooth conveying. The above utility model protects the packaging boxes, preventing them from falling out and ensuring stable conveying. When large cargo containers turn, the turning itself has a certain centrifugal force on the cargo. When multiple cargoes are transported together, they are easily squeezed and jammed at the curved guardrail, affecting the transport of cargo. Furthermore, during the output, since the straight conveyor track has no guardrail, cargo is prone to being thrown out and falling. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a bending machine folding plate guardrail, including a base frame, two sets of side frames welded and installed on the top of the base frame, multiple sets of conveying rollers fixedly installed between the side frames by bearings, guardrail frames fixedly installed on the top of the side frames by fixing bolts, and a positioning frame fixedly installed on the outer set of guardrail frames.

[0005] The bending machine is connected to the straight conveyor line and the goods are placed on the conveyor rollers for transportation. During the transportation process, the goods are protected by guardrails.

[0006] As a further preferred technical solution of this utility model, a grid frame is welded and installed between the side frames at the bottom of the conveying roller, and an electrical control structure is fixedly installed on the side of the side frame.

[0007] By setting up a grid frame, items that fall during the transport of goods over the top of the conveyor rollers are collected, preventing them from falling to the ground and being lost.

[0008] As a further preferred technical solution of this utility model, a drive motor is fixedly installed on one end of a set of conveying rollers on the side frame, and the output end of the drive motor passes through the side frame and is fixedly installed to one end of the conveying rollers. The outer end cross-sectional diameter of the conveying roller is larger than the inner end cross-sectional diameter. A transmission wheel is fixedly installed on the inner end of the conveying roller, and the transmission wheel has two sets of transmission grooves. The transmission wheels are connected and driven by a transmission belt.

[0009] A set of conveyor rollers is driven by a drive motor to rotate, which in turn works with multiple sets of drive wheels and drive belts to achieve the transmission effect of multiple sets of conveyor rollers.

[0010] As a further preferred technical solution of this utility model, the guardrail frame includes multiple sets of folded plates and a connecting frame for fixing the top and bottom of the folded plates. Folded plate recesses are provided between the folded plates. A connecting plate and an auxiliary plate are fixedly installed at both ends of the connecting frame, and mounting holes are provided on both the connecting plate and the auxiliary plate. The folded plates are fixedly installed by fixing bolts passing through the two sets of mounting holes.

[0011] By installing folded plates together, the overall length of the guardrail is increased to meet the required specifications. The recesses between the folded plates increase the clearance area compared to curved guardrails, thereby reducing the risk of items getting stuck or squeezed during transport.

[0012] As a further preferred technical solution of this utility model, the bottom of the positioning frame is provided with a base plate fixedly installed on the side frame. Multiple sets of positioning holes and sliding holes are respectively formed on the positioning frame and the base plate. The positioning holes and the sliding holes are the same size but different angles. A connecting ring is installed between the positioning frame and the base plate. Auxiliary holes are formed at both ends of the connecting ring. The connecting ring, the positioning frame, and the base plate are connected by sliding bolts passing through the positioning holes, the auxiliary holes, and the sliding holes. The connecting ring and the base plate are connected by positioning bolts passing through the auxiliary holes and the sliding holes.

[0013] The positioning frame, base plate, and connecting ring are installed together. When the goods are conveyed on the conveyor rollers, if the goods are large and squeeze the side of the positioning frame, the positioning frame will move inside the sliding hole by the sliding bolt, thus ensuring the protection of the goods while the positioning frame outputs stably.

[0014] As a further preferred technical solution of this utility model, an auxiliary roller is installed at one end of the positioning frame.

[0015] The driving force provided by the drive motor to the conveyor rollers transports the goods, and the auxiliary rollers slide the goods to output them.

[0016] Beneficial effects

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. By installing folded plates together, the overall length of the guardrail is increased to meet the required specifications. While providing some protection for goods during transportation, the recesses between the folded plates increase the clearance area compared to curved guardrails, thereby reducing the possibility of items getting stuck or squeezed during transport.

[0019] 2. The drive motor provides driving force to the conveyor rollers to transport the goods, and the auxiliary rollers slide the goods to output them. Through the interconnection of the positioning frame, base plate, and connecting ring, when the goods are being transported on the conveyor rollers, if the goods are large and cause pressure on the side of the positioning frame, the positioning frame will move within the sliding holes using sliding bolts. This ensures the protection of the goods while providing stable output, and also prevents the goods from being thrown out and falling due to the lack of guardrails on the linear conveyor track during output.

[0025] This specific embodiment is a bending plate guardrail for a curve machine.

[0026] The aforementioned utility model protects the packaging box, preventing it from falling out and ensuring stable transport. However, when large cargo boxes turn, the turn itself exerts a centrifugal force on the goods. When multiple cargo boxes are transported together, they are prone to being squeezed and jammed at the curved guardrail, affecting the transport of goods. Furthermore, during output, since the straight conveyor track has no guardrails, goods are prone to being thrown out and falling.

[0027] Its structural diagram is as follows Figures 1-4As shown. A bending machine guardrail includes a base frame 1 and two sets of side frames 11 welded to the top of the base frame 1. A grid frame 12 is welded and installed between the side frames 11 at the bottom of the conveyor rollers 2, and an electrical control structure 13 is fixedly installed on the side of the side frames 11. The grid frame 12 is used to collect objects that fall during the transport of goods over the top of the conveyor rollers 2, preventing them from falling to the ground and being lost. It also includes multiple sets of conveyor rollers 2 fixedly installed between the side frames 11 by bearings. A drive motor 24 is fixedly installed on one end of a set of conveyor rollers 2 on the side frame 11, and the output end of the drive motor 24 passes through the side frame 11 and is fixedly installed at one end of the conveyor roller 2. The outer cross-sectional diameter of the conveyor roller 2 is larger than the inner cross-sectional diameter. A transmission wheel 21 is fixedly installed on the inner end of the conveyor roller 2, and two sets of transmission grooves 23 are opened on the transmission wheel 21. The transmission wheels 21 are connected and driven by a transmission belt 22. A set of conveyor rollers 2 are driven by a drive motor 24 to rotate, thereby cooperating with multiple sets of transmission wheels 21 and transmission belts 22 to achieve a transmission effect. It also includes a guardrail frame 3 fixedly installed on the top of the side frame 11 by fixing bolts. The guardrail frame 3 includes multiple sets of folded plates 31 and connecting frames 32 for fixing the top and bottom of the folded plates 31. Folded plate notches 33 are provided between the folded plates 31. Connecting plates 34 and auxiliary plates 35 are fixedly installed at both ends of the connecting frame 32, and both connecting plates 34 and auxiliary plates 35 have mounting holes 36. The folded plates 31 are fixedly installed through the two sets of mounting holes 36 by fixing bolts. The installation of the folded plates 31 increases the overall length of the guardrail to meet the required requirements. While providing a certain degree of protection for goods during transportation, the folded plate notches 33 between the folded plates 31 increase the gap area compared to curved guardrails, thereby reducing the possibility of items being blocked or squeezed during transportation. It also includes a positioning frame 4 fixedly installed on the outer set of guardrail frames 3. The positioning frame 4 has a base plate 5 fixedly mounted on the side frame 11 at its bottom. Multiple sets of positioning holes 41 and sliding holes 51 are respectively opened on the positioning frame 4 and the base plate 5. The positioning holes 41 and sliding holes 51 are the same size but different angles. A connecting ring 6 is installed between the positioning frame 4 and the base plate 5. Auxiliary holes 61 are opened at both ends of the connecting ring 6. The connecting ring 6, the positioning frame 4, and the base plate 5 are connected by sliding bolts 43 passing through the positioning holes 41, auxiliary holes 61, and sliding holes 51. The connecting ring 6 and the base plate 5 are connected by positioning bolts 62 passing through the auxiliary holes 61 and sliding holes 51. Through the mutual installation of the positioning frame 4, the base plate 5, and the connecting ring 6, when goods are conveyed on the conveyor roller 2, if the goods are large and cause pressure on the side of the positioning frame 4, the positioning frame 4 will move within the sliding holes 51 by the sliding bolts 43. This ensures protection of the goods while providing stable output, and also prevents goods from being thrown out and falling due to the lack of guardrails on the linear conveyor track during output. An auxiliary roller 42 is installed at one end of the positioning frame 4.The driving force provided by the drive motor 24 to the conveying roller 2 is used to transport the goods, and the auxiliary roller 42 slides the goods to output them.

[0028] The bending machine is connected to the linear conveyor. Goods are placed on the conveyor rollers 2, and a set of conveyor rollers 2 is driven to rotate by the drive motor 24. This, in conjunction with multiple sets of transmission wheels 21 and transmission belts 22, enables the multiple sets of conveyor rollers 2 to achieve a transmission effect, allowing the goods to be conveyed on top of the conveyor rollers 2. The folding plates 31 are installed together to increase the overall length of the guardrail to meet the required requirements and to guide the goods. The folding plate recesses 33 provided between the folding plates 31 increase the gap area compared to curved guardrails, thereby reducing the possibility of items getting stuck or squeezed during conveying. The positioning frame 4, the base plate 5, and the connecting ring 6 are installed together. When the goods are conveyed on the conveyor rollers 2, if the goods are large and squeeze the side of the positioning frame 4, the positioning frame 4 will move inside the sliding hole 51 by the sliding bolt 43, thus ensuring the protection of the goods while the positioning frame 4 provides stable output.

[0029] All technical features in this embodiment can be freely combined according to actual needs.

[0030] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
