Detailed Implementation

[0028] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0029] This utility model provides a flexible double-belt flipping device for flipping workpieces during the conveying process, thereby enabling continuous flipping and conveying, and reducing the efficiency of workpiece feeding or conveying due to the need to flip workpieces.

[0030] Specifically, such as Figures 1-6 As shown, this utility model embodiment provides a flexible double-belt flipping device, including two opposing frames 100. A flipping assembly 200 for conveying and flipping workpieces is rotatably mounted on the frames 100. The flipping assembly 200 has a flipping channel 201 for conveying workpieces along the axial direction, and the flipping channel 201 is twisted 180 degrees along the axial direction. The flipping assembly 200 includes a first belt unit 210 and a second belt unit 220 that are arranged side by side and stacked in the vertical direction. The first belt unit 210 and the second belt unit 220 define the flipping channel 201 and clamp the workpiece within the flipping channel 201. An elastic deformation layer 202 is provided on the surface of the first belt unit 210 and the second belt unit 220 facing the flipping channel 201. During the process of clamping the workpiece and conveying it along the flipping channel 201, the elastic deformation layer 202 undergoes conformal elastic deformation along the contour of the workpiece surface when clamping the workpiece.

[0031] In the process of turning over the workpiece, the workpiece is placed in the turnover channel 201, wherein the turnover channel 201 is defined by the two first and second belt units 210 and 220 stacked in the up-down direction, so that after the workpiece is placed in the turnover channel 201, the workpiece is placed on one of the belt units and clamped by the other belt unit on the upper side, so that the workpiece is conveyed during the transmission of the belt units. At this time, since the turnover channel 201 is twisted by one hundred and eighty degrees along the axis direction, the workpiece is gradually turned over during the conveying process to follow the twisting of the turnover channel 201, so as to realize the turning over of the workpiece by one hundred and eighty degrees. The elastic deformation layer 202 is arranged on both the belt units, so that after the workpiece is placed in the turnover channel 201, the two belt units clamp the workpiece, so that the elastic deformation layer 202 elastically deforms to follow the surface profile of the workpiece, and the elastic deformation shape is similar to the surface profile shape of the workpiece, so as to ensure that the workpiece does not fall in the turnover channel 201 during the turning over process following the turnover channel 201, and the stability of the workpiece turning over and conveying is ensured.

[0032] In the embodiment, as shown in Figures 4-5 The first belt unit 210 includes a first driving shaft 211, a first driven shaft 212 and a first conveying belt 213. The first driving shaft 211 and the first driven shaft 212 are rotatably connected to the rack 100. The first conveying belt 213 is twisted by one hundred and eighty degrees along the axis, and the two ends of the first conveying belt 213 are respectively sleeved on the first driving shaft 211 and the first driven shaft 212. The first conveying belt 213 is gradually inclined from the two ends to the middle position, and the middle part defines a first turnover part 214 arranged in the vertical direction. The second belt unit 220 includes a second driving shaft 221, a second driven shaft 222 and a second conveying belt 223. The second driving shaft 221 and the second driven shaft 222 are rotatably connected to the rack 100. The second conveying belt 223 is twisted by one hundred and eighty degrees along the same twisting direction as the first conveying belt 213, and the two ends of the second conveying belt 223 are respectively sleeved on the second driving shaft 221 and the second driven shaft 222. The first conveying belt 213 is gradually inclined from the two ends to the middle position, and the middle part defines a second turnover part 224 arranged in the vertical direction and corresponding to the first turnover part 214.

[0033] In the embodiment, the first conveying belt 213 and the second conveying belt 223 are arranged in parallel and close to each other, so as to define a turnover channel 201 for conveying and overturning the workpiece. During the transmission of the two conveying belts, the conveying action of the workpiece is realized, and at the same time, the two conveying belts are twisted in the same direction, so as to realize the twisting of the conveying channel, and the first turnover part 214 and the second turnover part 224 are in a vertical state at a position corresponding to the position, which is also the critical point of the workpiece during the conveying process in the turnover channel 201. After passing through the turnover part, the workpiece is gradually overturned to another surface facing upward (that is, the surface previously facing downward is overturned to face upward).

[0034] More specifically, the first driving shaft 211 is located on the upper side of the second driving shaft 221, and the first driven shaft is located on the lower side of the second driven shaft 222. Thus, the normal transmission of the first conveying belt 213 and the second conveying belt 223 after overturning can be realized.

[0035] In the embodiment, the first conveying belt 213 and the second conveying belt 223 have the same structure, that is, the first conveying belt 213 and the second conveying belt 223 each include a belt body layer 215 and an elastic deformation layer 202. The elastic deformation layer 202 is attached to the belt body layer 215, and is composed of one of foam material, fiber cotton material, and cotton and hemp material. During the conveying of the workpiece, when the workpiece is placed in the turnover channel 201, the elastic deformation layer 202 is elastically deformed to follow the contour of the surface of the workpiece due to the clamping and compression of the first conveying belt 213 and the second conveying belt 223 on the workpiece. After deformation, the shape is shaped according to the contour of the workpiece, that is, the workpiece is embedded in the elastic deformation layer 202. Thus, during the conveying and overturning of the workpiece, the workpiece can be kept stable under the limitation of the elastic deformation layer 202, avoiding the situation of falling in the turnover channel 201. In the embodiment, the belt body layer can be composed of the conveying belt in the prior art, and the elastic deformation layer composed of foam is attached to the belt body layer.

[0036] In the embodiment, in order to adjust the gap between the turnover channels 201, so as to adapt to workpieces of different thicknesses and keep sufficient clamping force, an adjusting unit 300 is further arranged on the rack 100 to adjust the distance between the turnover channels 201. The adjusting unit 300 is arranged between the first belt unit 210 and the second belt unit 220, and includes four clamping rollers 301. Each two clamping rollers 301 are oppositely arranged on the upper side and the lower side of the turnover assembly 200, and are respectively arranged in the first conveying belt 213 and the second conveying belt 223.

[0037] That is to say, a clamping roller 301 is arranged at the driving end and the driven end of the first conveying belt 213, and a clamping roller 301 is arranged at the driving end and the driven end of the second conveying belt 223 as well. The two clamping rollers 301 which are not located at the same end are arranged corresponding to each other in the up-down direction, so that the corresponding parts of the first conveying belt 213 and the second conveying belt 223 can be interfered, and the gap of the turnover channel 201 can be adjusted by separating or approaching under the interference of the up-down opposite clamping rollers 301.

[0038] In order to better adjust, a sliding groove in the vertical direction is arranged at the corresponding position of the clamping roller 301 on the rack 100. The two ends of the clamping roller 301 are connected to the sliding groove 101 in the vertical direction, and the two ends of the clamping roller 301 are respectively provided with fasteners for locking in the sliding groove 101. In this embodiment, the clamping roller 301 slides along the sliding groove 101, so that the gap between the two clamping rollers 301 can be changed, and the gap of the turnover channel 201 can be adjusted. The fastener can be a bolt screwed on the end of the clamping roller 301, so that after the bolt is screwed, the nut is fastened with the rack 100, so that the clamping roller 301 can be fixed in the sliding groove 101.

[0039] In this embodiment, in order to drive the two conveying belts, a driving motor 110 is arranged on the rack 100, and the end of the first driving shaft 211 and the second driving shaft 221 is fixedly provided with a synchronous wheel 111. The driving motor 110 drives the first driving shaft 211 and the second driving shaft 221 to rotate in opposite directions through the synchronous wheel 111. By driving the two conveying belts with the same driving motor 110, the surface transmission direction and speed of the two conveying belts defining the turnover channel 201 are the same, so as to ensure the stability of the transmission and turnover of the workpiece in the turnover channel 201.

[0040] In order to adjust the tensioning of the two conveying belts and adjust in the process of running off, Figures 2-3As shown, the first driven shaft 212 and the second driven shaft 222 each include a shaft body 2121 and a sleeve 2122 rotatably connected to the shaft body 2121; meanwhile, the rack 100 is further provided with two tensioning structures corresponding to the first driven shaft 212 and the second driven shaft 222 respectively, the tensioning structure includes a fixed seat and a pulling member, wherein the seat body 121 is provided with a tensioning groove 122 facing the direction of the other end of the rack 100, the shaft body 2121 is slidably connected to the tensioning groove 122 at both ends, the seat body 121 is provided with a through hole 123 on the side wall away from the turnover assembly 200, one end of the pulling member passes through the through hole 123 and is threadedly connected with the end of the shaft body 2121, and the other end constitutes a rotating end for rotating the pulling member. In the embodiment, the pulling member is also a bolt, by rotating the rotating end of the bolt, the shaft body 2121 can be pulled to move in the length direction of the tensioning groove 122, thereby adjusting the position of the shaft body 2121, adjusting the deviation or loosening of the conveying belt, and ensuring the reliability of the conveying.

Although the present application is disclosed in the preferred embodiment, it is not intended to limit the present application.
