Description

Technical Field

[0001] This application relates to the field of transmission device technology, and in particular to a non-powered connection suitable for the transition section of a line. Background Technology

[0002] With the optimization of various technologies in the production line, the factory's ground transportation line has gradually been optimized into a plate chain conveyor line. Plate chain conveyors have a large load capacity, run smoothly, and are durable, making them ideal conveying equipment for large materials, and they are widely used.

[0003] Common plate chain conveyor lines are mainly formed by connecting multiple plate chain conveyor belts end to end. During the conveying process, due to the large turning radius of the plate chains, materials cannot pass through normally because there is no support at the joint. In existing technology, to avoid this situation where materials cannot pass normally due to the excessive turning path of the plate chains, a non-powered plate chain is often installed between the two conveyor belts to achieve the connection. The underside of the plate chain is supported by a support plate.

[0004] However, due to the high friction between the non-powered plate chain and the supporting plate, the material is propelled by the powered plate chain, while the non-powered plate chain is forced to move forward. When the friction coefficient between the material and the plate chain is less than that between the non-powered plate chain and the supporting plate, the material will have difficulty moving forward. In addition, the need for the powered and non-powered plate chains to maintain the same height is also a key factor affecting the material's movement. Therefore, in order to ensure that the material can transition smoothly, it is necessary to reduce the friction of the non-powered section as much as possible. Utility Model Content

[0005] In order to reduce friction in the unpowered section and ensure smooth material transfer, this application provides an unpowered connection suitable for the transition section of the production line.

[0006] The technical solution provided in this application for a non-powered connection suitable for the transition section of a production line adopts the following:

[0007] A non-powered connection suitable for the transition section of a production line includes a front power plate chain and a rear power plate chain. The front power plate chain includes a plurality of front plate chain units arranged along the conveying direction of the conveyor line, and the plurality of front plate chain units are arranged in parallel. The rear power plate chain includes a plurality of rear plate chain units arranged along the conveying direction of the conveyor line, and the plurality of rear plate chain units are arranged in parallel.

[0008] Several support frames are fixedly installed between the front power plate chain and the rear power plate chain. One end of the support frame is located between two adjacent front plate chain units, and the other end of the non-powered connection is located between two adjacent rear plate chain units.

[0009] A support plate is fixedly connected to the top of the support frame, and a roller chain is rotatably mounted on the support plate, with the top surface of the roller chain flush with the top surfaces of the front plate chain unit and the rear plate chain unit.

[0010] The bottom of the support frame is equipped with a support structure for supporting the roller chain.

[0011] By adopting the above technical solution, when the material is conveyed to its tail end along the front power plate chain, the material is connected by the roller chain at the top of the support frame. Since the material part is still in contact with the front power plate chain, the roller chain can be driven by the friction between the material and the roller chain. Since the roller chain is rolled on the support plate, there is rolling friction between the roller chain and the support plate. The friction force that the roller chain needs to overcome between itself and the support plate is small, which is smaller than the sliding friction force that the traditional non-powered plate chain needs to overcome between itself and the support plate. This ensures that the material is conveyed more smoothly from the front power plate chain to the rear power plate chain.

[0012] Preferably, the support frame has two limiting holes through which the roller chain passes, and the two limiting holes are located at the front and rear ends of the support plate.

[0013] By adopting the above technical solution, the left and right sides of the roller chain can be limited by the two limiting holes, reducing the occurrence of roller chain displacement and detachment.

[0014] Preferably, the support plate is integrally formed with a plurality of support rails arranged along the length direction of the support plate, the plurality of support rails are evenly arranged along the width direction of the support plate, the rollers of the roller chain roll in coordination with the rolling of the support rails, and the chain plates of the roller chain are all located on both sides of the support rails.

[0015] By adopting the above technical solution, the rollers on the roller chain are in direct contact with the support rails on the support plate, which facilitates the rollers of the roller chain to roll over the support plate and realize the conveying of materials.

[0016] Preferably, the top corners of the front and rear ends of the support plate and the plurality of support rails are rounded.

[0017] By adopting the above technical solution, the rounded corners at the top edges of the support plate and the front and rear ends of the support rail can improve the smoothness of the roller conveying of the roller chain.

[0018] Preferably, the support structure includes a first support rod and a second support rod, an idler wheel is fixedly installed on the first support rod, and a support wheel is fixedly installed on the second support rod. The idler wheel and the support wheel are parallel to each other, and both the idler wheel and the support wheel are arranged along the width direction of the roller chain.

[0019] Both the idler wheel and the support wheel have a plurality of convex rings integrally formed on their surfaces to match the rollers of the roller chain. The rollers of the roller chain roll in cooperation with the convex rings, and the chain plates of the roller chain are located on both sides of the convex rings.

[0020] By adopting the above technical solution, the idler wheel installed on the first support rod and the support wheel installed on the second support rod can give the roller chain a certain tension, thereby improving the stability of the roller chain transmission.

[0021] In summary, the non-powered connection method applicable to the transition section of the production line proposed in this application has at least one of the following beneficial technical effects:

[0022] 1. When the material is conveyed to its tail end along the front power plate chain, the material is connected by the roller chain at the top of the support frame. Since the material part is still in contact with the front power plate chain, the roller chain can be driven by the friction between the material and the roller chain. Since the roller chain is rolled on the support plate, there is rolling friction between the roller chain and the support plate. The friction between the roller chain and the support plate that the roller chain needs to overcome is smaller. Compared with the sliding friction between the roller chain and the support plate that the traditional non-powered plate chain needs to overcome, it is smaller, which can ensure that the material is conveyed more smoothly from the front power plate chain to the rear power plate chain.

[0023] 2. The roller chain can be limited on both sides by two limiting holes, reducing the occurrence of roller chain displacement or detachment;

[0024] 3. By using the idler wheel installed on the first support rod and the support wheel installed on the second support rod, the roller chain can be given a certain tension, which improves the stability of the roller chain drive. Attached Figure Description

[0031] The following combination Figures 1-5 This application will be described in further detail.

[0032] Example

[0033] This application discloses a non-powered connection suitable for line transition sections. (Refer to...) Figures 1-4 It mainly includes a front power plate chain and a rear power plate chain. The front power plate chain includes several front plate chain units 1 arranged along the conveying direction of the conveyor line, and the several front plate chain units 1 are arranged in parallel. The rear power plate chain includes several rear plate chain units 2 arranged along the conveying direction of the conveyor line, and the several rear plate chain units 2 are arranged in parallel.

[0034] Several support frames 3 are fixedly installed between the front power plate chain and the rear power plate chain. One end of the support frame 3 is located between two adjacent front plate chain units 1, and the other end without power connection is located between two adjacent rear plate chain units 2.

[0035] A support plate 4 is fixedly connected to the top of the support frame 3. A roller chain 5 is rolled on the support plate 4, and the top surface of the roller chain 5 is flush with the top surfaces of the front plate chain unit 1 and the rear plate chain unit 2.

[0036] In order to maintain a certain tension on the roller chain 5, in this embodiment, a support structure for supporting the roller chain 5 is installed at the bottom of the support frame 3.

[0037] When the material is conveyed to its tail end along the front power plate chain, it is connected by the roller chain 5 at the top of the support frame 3. Since the material part is still in contact with the front power plate chain, the roller chain 5 can be driven by the friction between the material and the roller chain 5. Since the roller chain 5 is rolled on the support plate 4, there is rolling friction between the roller chain 5 and the support plate 4. The friction force that the roller chain 5 needs to overcome with the support plate 4 is small, which is smaller than the sliding friction force that the traditional unpowered plate chain needs to overcome with the support plate 4. This ensures that the material is conveyed more smoothly from the front power plate chain to the rear power plate chain.

[0038] It should be noted that in this embodiment, there are three front plate chain units 1 and three rear plate chain units 2, and two non-powered connections. One end of the non-powered connection is located between two adjacent front plate chain units 1, and the other end is located between two adjacent rear plate chain units 2. In some other embodiments, the number of non-powered connections can be increased or decreased depending on the number of front plate chain units 1 and rear plate chain units 2, which will not be limited or elaborated here.

[0039] Reference Figure 3 Two limiting holes 31 are provided through the support frame 3 for the roller chain 5 to pass through. The two limiting holes 31 are located at the front and rear ends of the support plate 4. The two limiting holes 31 can limit the left and right sides of the roller chain 5, reducing the occurrence of displacement or detachment of the roller chain 5.

[0040] Reference Figure 5 The support plate 4 has a plurality of support rails 41 integrally formed on it along the length of the support plate 4. The plurality of support rails 41 are evenly arranged along the width of the support plate 4. The rollers of the roller chain 5 roll in coordination with the rollers of the support rails 41. The chain plates of the roller chain 5 are all located on both sides of the support rails 41.

[0041] The rollers on the roller chain 5 are in direct contact with the support rail 41 on the support plate 4, which facilitates the rollers of the roller chain 5 to roll through the support plate 4 and realize the conveying of materials.

[0042] Reference Figure 4 The top corners of the front and rear ends of the support plate 4 and several support rails 41 are all rounded.

[0043] The rounded corners at the top edges of the support plate 4 and the support rail 41 at both ends can improve the smoothness of the roller conveying of the roller chain 5.

[0044] Reference Figures 3-5 The support structure includes a first support rod 32 and a second support rod 33. An idler wheel 34 is fixedly installed on the first support rod 32, and a support wheel 35 is fixedly installed on the second support rod 33. The idler wheel 34 and the support wheel 35 are parallel to each other, and both the idler wheel 34 and the support wheel 35 are arranged along the width direction of the roller chain 5.

[0045] Both the idler wheel 34 and the support wheel 35 have a number of convex rings 341 integrally formed on their surfaces, which are adapted to the rollers of the roller chain 5. The rollers of the roller chain 5 roll in cooperation with the convex rings 341, and the chain plates of the roller chain 5 are located on both sides of the convex rings 341.

[0046] By using the idler wheel 34 mounted on the first support rod 32 and the support wheel 35 mounted on the second support rod 33, the roller chain 5 can have a certain tension, thereby improving the stability of the roller chain 5 transmission.

[0047] The first support rod 32 and the second support rod 33 are integrally formed with two connecting arms. The idler wheel 34 and the support wheel 35 are both mounted on the connecting arms by pins. Both ends of the idler wheel 34 and the support wheel 35 are provided with slots that are adapted to the connecting arms, and the idler wheel 34 and the support wheel 35 are limited by the slots.

[0048] The implementation principle of a non-powered connection applicable to the transition section of the production line in this application embodiment is as follows: When the material is conveyed to its tail end along the front power plate chain, the material is connected by the roller chain 5 at the top of the support frame 3. Since the material part is still in contact with the front power plate chain, the roller chain 5 can be driven by the friction between the material and the roller chain 5. Since the roller chain 5 is rolled on the support plate 4, the roller chain 5 and the support plate 4 have rolling friction. The friction force that the roller chain 5 needs to overcome with the support plate 4 is small, which is smaller than the sliding friction force that the traditional non-powered plate chain needs to overcome with the support plate 4. This can ensure that the material is conveyed more smoothly from the front power plate chain to the rear power plate chain.

[0049] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
