[0001] This application relates to the field of profile conveying technology, and more specifically, to a flexible conveying component and conveying device. Background Technology

[0002] In the existing technology, the profiles extruded by the extrusion equipment are tens of meters long. The extruded profiles need to be received and transported to a designated location by the conveyor line under high temperature and high pressure. Usually, the conveyor line at the outlet of the main extrusion equipment adopts a fixed roller, which has a simple structure and reliable operation.

[0003] However, when extruding thin-walled, large-diameter, and high-precision cylinder materials, the profile's own weight and thin walls, as well as the hard contact with the fixed roller, may cause the profile to deform when in contact with some of the rollers, resulting in non-compliance with roundness and inner diameter dimensions, making it impossible to produce stable qualified products.

[0004] Therefore, a flexible transfer component and conveying device are needed to solve the above problems. Utility Model Content

[0033] Figure 1 This is a schematic diagram of the flexible transfer component used in the first embodiment of this application. Figure 2 for Figure 1 A schematic diagram of the idler rollers of the flexible transfer assembly is shown. Figure 1 and Figure 2 As shown, the flexible transmission assembly 1000 includes a support 5, a flexible transmission unit 10, and a primary elastic structure 3.

[0034] The flexible transfer assembly 1000 includes at least one pair of opposing supports 5; each pair of supports 5 includes two opposing supports 5, and the flexible transfer unit 10 is located between the two supports 5.

Each flexible transmission unit 10 includes a primary rotating shaft 2, two primary connecting plates 1, and at least one pair of idler rollers 4. The opposite ends of the primary rotating shaft 2 are rotatably connected to two supports 5 or mating parts (if a multi-stage structure exists, the mating part is a secondary connecting plate 11). The two primary connecting plates 1 are arranged opposite to and spaced apart on the primary rotating shaft 2, and the primary rotating shaft 2 is rotatably connected to the primary connecting plates 1. The surface of the idler rollers 4 can be configured as a soft contact surface. At least one pair of idler rollers 4 are respectively arranged on opposite sides of the primary rotating shaft 2, and the opposite ends of each idler roller 4 are rotatably connected to the primary connecting plates 1. The primary rotating shaft 2 can be a single shaft, with both ends passing through the two primary connecting plates 1; or it can be two shafts, with one shaft connected to each primary connecting plate 1. To achieve precise control, each flexible transmission unit 10 has a symmetrical structure, with one idler roller 4 arranged on each side of the primary rotating shaft 2, and the idler rollers 4 are capable of reciprocating rotation. Multiple flexible transmission units 10 are typically set to extend the length of flexible transmission, ensuring that the force is balanced when the profiles first come into contact, thus avoiding deformation.

[0036] The idler roller 4 includes a roller 41, a roller cover 42, an idler roller shaft 43, a fixed cover plate 44, a bearing 45, and a set screw 46.

Both ends of the idler roller shaft 43 are provided with bearings 45 and are fixed by set screws 46. The idler roller shaft 43 is rotatably connected to the primary connecting plate 1 through the bearings 45.

[0037] The flexible transfer assembly 1000 includes a primary elastic structure 3, which is used to maintain the relative balance of adjacent flexible transfer units 10 in a static state.

[0038] The flexible transfer assembly 1000 described above, with its rotatable connection between the primary rotating shaft 2 and the support 5, provides the flexible transfer unit 10 with a certain degree of flexibility in the height direction. During use, it can slightly float up and down according to the shape of the profile, providing both support and preventing deformation of the profile. A primary elastic structure 3 is incorporated to maintain the relative balance of adjacent flexible transfer units 10 in a static state, preventing excessive tilting. The flexible transfer unit 10 transforms hard contact into flexible contact, preventing deformation of the extruded profile during transportation, balancing the force on the profile, improving the roundness of large-diameter thin-walled profiles, and increasing the yield rate.

By adopting the above structure, a balancing effect is effectively achieved, while ensuring flexible support for the profile.

The secondary elastic structure 13 is used to maintain the relative balance of the secondary connecting plate 11 and adjacent connecting plates (such as primary connecting plate 1 or tertiary connecting plate 111) in a static state. By setting up a multi-stage structure, the relative balance of the flexible transmission component 1000 in a static state can be guaranteed, as well as effective support for the profile, avoiding any impact on the shape of the profile.

Figure 9 As shown, the flexible transmission assembly 1000 has a three-stage structure. The two opposite ends of the three-stage rotating shaft 112 are rotatably connected to two supports 5. Two three-stage connecting plates 111 are arranged opposite to and spaced apart on the three-stage rotating shaft 112, and the three-stage rotating shaft 112 is rotatably connected to the three-stage connecting plates 111. Within the three-stage structure, two secondary structures are symmetrically distributed on opposite sides of the three-stage rotating shaft 112, each secondary structure being a flexible transmission element 100.

The conveying device can include conventional drive rollers or a flexible transfer assembly 1000 consisting of two, four, or eight balancing rollers, typically eight balancing rollers, with each eight balancing rollers equipped with a pair of supports 5. The flexible transfer assembly 1000 is positioned near the extruder outlet; for example, the conveyor line within 6 meters uses the flexible transfer assembly 1000, while the rest uses conventional drive rollers.

[0059] As can be seen from the above description and practice, the flexible transfer assembly and conveying device provided in this application have the following advantages compared with the prior art: Using the aforementioned flexible transfer assembly, because the primary rotating shaft and the support are rotatably connected, the flexible transfer unit has a certain degree of flexibility in the height direction. During use, it can float slightly up and down according to the shape of the profile, allowing the flexible transfer unit to provide close support while preventing deformation of the profile. By setting a primary elastic structure, the relative balance of adjacent flexible transfer units in static conditions is maintained, preventing excessive tilting of the flexible transfer units. The flexible transfer unit transforms hard contact into flexible contact, preventing deformation of the profile extruded by the extrusion equipment during transportation, balancing the force on the profile, improving the roundness forming of large-diameter thin-walled materials, and increasing the yield rate.
