The specific implementation mode is as follows:
for the purpose of illustrating the technical solutions of the present invention, the present invention will be described below with reference to the accompanying drawings used in the examples:
the technical scheme of the invention is that the prior patent (with the grant publication number of CN 210054480U)
As can be seen from the description of the prior patent (with the publication number of CN 210054480U) and the attached drawing 1, the tea tray of the prior patent is centrally and symmetrically provided with a fulcrum trepanning at each end, and the fulcrum trepanning is inserted into the long pin shaft of the conveying chain, so that the conveying chains at both sides of the device synchronously move to drive the meshed tea tray to move, and the meshed tea tray can be transferred from the upper layer to the lower layer. However, through operation, the swinging amplitude of the tray from the upper layer to the lower layer is too large due to manufacturing errors, chain tension, long pin shaft strength and the like, and when the mesh tea tray is in a turning state in which the mesh tea tray is transferred from the upper layer to the lower layer, the mesh tea tray is easy to incline, so that the swinging amplitude of the tray from the upper layer to the lower layer is too large, and the unstable state of the tea tray is caused. Through repeated research and repeated tests, the inventor finds a solution that a chain wheel (layer wheel for short) is added on each layer of the short side with the dislocation of the conveying chain, the layer wheel and the conveying chain wheel have the same mold and the same tooth, the horizontal distance with the original short side conveying chain wheel of the device is equal to the distance (12 pitches) between a fulcrum trepanning hole of the tray and the idle wheel, the layer wheel and the conveying chain wheel run synchronously through a layer wheel transmission chain, and when the idle wheel of the tray runs to the layer wheel, the layer wheel just falls into a tooth groove of the layer wheel and runs synchronously along with the layer wheel, so that the tray cannot swing. Then the layer wheel locks the idle wheel of the next pallet, and the process is repeated.
The technical scheme for overcoming the technical problem is that an idle wheel (4-1,4-2) is added in an axisymmetric mode on fulcrum sleeve holes (2-1,2-2) at two ends of a new tea hole tray 1, and a ditch-crossing wheel (3-1,3-2) is added between the fulcrum sleeve holes at two ends of the tray and the idle wheel respectively, 4 wheels are additionally arranged on the new tea hole tray, the two idle wheels are used for transferring the tray from an upper layer to a lower layer, the two ditch-crossing wheels in the middle are used for crossing a guide groove, the diameters of the idle wheel and the ditch-crossing wheel are the same as the diameter of a roller of a conveying chain, and the distance between the idle wheel and the ditch-crossing wheel is larger than the width of the guide groove.
As can be seen from fig. 2, the fulcrum trepanning at the two ends of the new mesh tea tray is also inserted into the long pin shafts of the conveying chains 7 at the two sides of the device to be connected together, and the conveying chains 7 at the two sides move to drive the new mesh tea tray to move in parallel. The new hole tea tray of the improved tea drying compound withering device is connected with the long pin shaft of the conveying chain 7 on the conveying guide groove 6 when the new hole tea tray is transferred from the upper layer to the lower layer, the idle wheel 4-1 and the channel spanning wheel 3-1 of the tray pass through two guide grooves, namely the conveying guide groove 6 and the idle wheel guide groove 8, a gap (also called a ditch) is arranged between the conveying guide groove 6 and the idle wheel guide groove 8, the gap is used for passing through the conveying chain 7, and the distance between the idle wheel 4-1 of the tray and the channel spanning wheel 3-1 is slightly larger than the gap distance (the ditch width). The wheel 3-1 is on the conveying channel 6 when the wheel 4-1 is in the middle of the groove, the wheel 3-1 is on the conveying channel 6 when the wheel 4-1 reaches the wheel channel 8, the wheel 4-1 is on the wheel channel 8 when the wheel 3-1 is in the middle of the groove, and the end of the tray is at least two points on the channel, so that the wheel 3-1 and the wheel 4-1 can cross the gap between the conveying channel 6 and the wheel channel 8, and the wheels can not fall under the groove. And the pivot trepanning 2-2, the ditch-spanning wheel 3-2 and the idle wheel 4-2 at the other end of the tray are all arranged on the conveying guide groove at the other side of the device, and the tea tray in the new net hole synchronously and stably moves on the guide groove along with the conveying chains at the two sides.
The idler wheel guide groove 8 is provided with an arc-shaped guard plate 5, the arc-shaped guard plate 5 is used for guiding the idler wheel 4-1 arranged on the new mesh tea tray, when the idler wheel 4-1 of the new mesh tea tray runs to the layer wheel 11, the idler wheel is just clamped in the tooth grooves of the layer wheel 11, so that the tray 1 cannot swing and runs synchronously with the layer wheel 11. As can be seen from figure 3, when the new tea tray row is transferred from the upper layer to the next layer, when the pivot trepanning 2-1 connected with the conveying chain 7 enters the next layer along with the conveying chain wheel 10, the gutter-crossing wheel 3-1 and the idle wheel 4-1 arranged on the new tea tray also enter the next layer along with the layer wheel 11. The layer wheel 11 is synchronous with the conveying chain wheel 10 through the connection of the layer wheel transmission chain 9, so that the meshed tea tray cannot incline to cause instability of the tea tray when being transferred from the upper layer to the lower layer. The short sides of the improved device with the staggered conveying chains at the two sides are designed identically for each layer.
Similarly, due to manufacturing errors, chain tension, long pin shaft strength and the like, the swinging amplitude of the meshed tea tray is overlarge when the tail part of the whole machine rises, and through repeated research and repeated tests, the inventor finds a solution that an independent circulating chain (called a tail chain for short) is additionally arranged on the short side of the tail part of the whole machine, the tail chain and a conveying chain are of the same type, the length of the tail chain is an integral multiple of the distance (25 pitches) between the new meshed tea tray, a duckbill structure is arranged on each 25 pitches of the tail chain, the duckbill width is slightly larger than the diameter of an idler wheel of the tray, the duckbill is perpendicular to the tail chain, and the duckbill mouth faces outwards. The tail chain passes through duckbilled driving chain and carries chain synchronous operation, the horizontal distance that the tailwheel equals the fulcrum trepanning of tray and the distance (12 pitches) of idler with device afterbody conveying sprocket, the tailwheel is with the mould with the tooth with conveying sprocket, just blocked by the duckbill when the tail wheel is tangent down in operation of new mesh tealeaves tray idler to along with duckbill synchronous operation, the tray just can not waved like this, break away from the duckbill and move separately when new mesh tealeaves tray idler moves last tail wheel and is tangent. The duckbill is then rotated to the original tangent point to jam the next new mesh tea tray idler pulley and so on. As can be seen from figure 4, the inventor adds the tail chain 12 on the short side of the tail part of the whole machine, the length of the tail chain is integral multiple of 25 pitches (the distance between the new mesh tea trays), every 25 pitches is provided with a duckbill structure 13, the duckbill width is slightly larger than the diameter of the tray idler wheel 4-2, the duckbill is vertical to the tail chain 12, and the duckbill faces outwards. The tail chain 12 moves synchronously with a conveying chain 17 for conveying the new mesh tea tray through a duckbill driving chain 16, and the duckbill driving chain 16 connects a lower tail wheel 15 of the tail chain 12 with a conveying chain wheel 14 of the conveying chain 17 for conveying the new mesh tea tray. When the new mesh tea tray idler pulley 4-2 runs tangential to the tail chain 12, it is just caught by the duckbill 13 and runs synchronously with the duckbill, so that the new mesh tea tray does not swing when ascending, and when the new mesh tea tray idler pulley 4-2 runs tangential to the tail pulley 18 of the tail chain 12, it runs separately from the duckbill. The duckbill is then turned to the point of origin to jam the rear mesh tea tray idler pulley 4-2 and so on.
Taking the design of the embodiment as an example, the conveying chain uses C216AH, the pitch is 50.8mm, the new tea hole trays are 3000mm long and 1200mm wide, the tea hole trays are 70mm apart (the gap between the trays), and the distance between the new tea hole trays is 25 mm (1270 mm); the fulcrum trepan was spaced 12 pitches (609.6 mm) from the idler, the geneva wheel was spaced 130mm from the idler, and the width of the channel between the delivery and idler channels was 110 mm.
