The specific embodiment is as follows:
For the purpose of illustrating the technical solution of the present invention, the present invention is described below with reference to the accompanying drawings used in the embodiments:
the technical proposal of the invention is that in the prior patent (the issued bulletin number is CN 210054480U)
As can be seen from the description of the prior patent (publication No. CN 210054480U) and fig. 1, the two ends of the tea tray of the prior patent are provided with a pivot sleeve hole symmetrically at the center, the pivot sleeve holes are inserted into the long pin shafts of the conveying chains, so that the synchronous movement of the conveying chains at two sides of the device brings the mesh tea tray to travel and can be transferred from the previous layer to the next layer. However, through operation, the problem that the swing amplitude is too large when the tray is from the upper layer to the lower layer due to the reasons of manufacturing errors, chain tension, long pin shaft strength and the like is found, when the mesh tea tray is in a turning state when the row of 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 swing amplitude is too large when the tray is from the upper layer to the lower layer, and the tea tray is in an unstable state. The inventor finds a solution through repeated research and repeated experiments that a sprocket wheel (layer wheel for short) is respectively added on each layer on the short side of the dislocation of the conveying chain, the layer wheels and the conveying sprocket wheel are same in mode and same in teeth, the horizontal distance between the layer wheels and the conveying sprocket wheel on the original short side of the device is equal to the distance between a fulcrum sleeve hole of a tray and an idler wheel (12 pitches), the layer wheels and the conveying sprocket wheel synchronously run through the layer wheel transmission chain, and when the tray idler wheel runs to the layer wheels, the tray just falls into tooth grooves of the layer wheels and synchronously runs along with the layer wheels, so that the tray cannot swing. The idler wheel of the next tray is then caught again by the layer wheel, and so on.
The novel mesh tea tray 1 has the technical scheme that the supporting point sleeve holes (2-1, 2-2) at two ends of the novel mesh tea tray 1 are axially symmetrically provided with idler wheels (4-1, 4-2), the supporting point sleeve holes at two ends of the tray and the idler wheels are respectively provided with a groove crossing wheel (3-1, 3-2), the novel mesh tea tray is provided with 4 wheels, two idler wheels are used for transferring the tray from an upper layer to a lower layer, the middle two groove crossing wheels are used for crossing a groove, the diameters of the idler wheels and the groove crossing wheels are the same as the diameter of rollers of a conveying chain, and the distance between the idler wheels and the groove crossing wheels is larger than the width of the groove of the guide groove.
As can be seen from fig. 2, the fulcrum sleeve holes at the two ends of the new mesh tea tray are also connected together by being inserted on the long pin shafts of the conveying chains 7 at the two sides of the device, and the conveying chains 7 at the two sides move to drive the new mesh tea tray to move in parallel. The new mesh tea tray of the improved tea drying compound withering device is characterized in that when the new mesh tea tray is transferred from the previous layer to the next layer, the pivot sleeve hole 2-1 and the long pin shaft of the conveying chain 7 are connected together and positioned on the conveying guide groove 6, the idler wheel 4-1 and the crossing groove wheel 3-1 of the tray pass through two guide grooves, one is the conveying guide groove 6 and the other is the idler wheel guide groove 8, a gap (commonly called a groove) is reserved between the conveying guide groove 6 and the idler wheel guide groove 8, and the gap is used for passing through the conveying chain 7, and the distance between the idler wheel 4-1 and the crossing groove wheel 3-1 of the tray is slightly larger than the gap distance (groove width). The idler wheel 4-1 is on the conveying guide groove 6 when the idler wheel 4-1 is in the middle of the groove, the idler wheel 3-1 is also on the conveying guide groove 6 when the idler wheel 4-1 reaches the idler wheel guide groove 8, the idler wheel 4-1 is on the idler wheel guide groove 8 when the idler wheel 3-1 is in the middle of the groove, at least two points of the end of the tray are on the guide groove, and therefore the idler wheel 4-1 and the idler wheel 3-1 can span the gap between the conveying guide groove 6 and the idler wheel guide groove 8, and neither wheel falls under the groove. The fulcrum sleeve hole 2-2, the cross-grooved wheel 3-2 and the idler 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 new-mesh tea tray 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 guard plate 5, the arc guard plate 5 is used for guiding the idler wheel 4-1 arranged on the new mesh tea tray, and when the new mesh tea tray idler wheel 4-1 runs to the layer wheel 11, the idler wheel is just clamped in the tooth groove of the layer wheel 11 so that the tray 1 can not swing and synchronously runs along with the layer wheel 11. As can be seen from fig. 3, as the row of new mesh tea trays is transferred from the upper layer to the lower layer, when the fulcrum sleeve holes 2-1 connected with the conveying chain 7 enter the lower layer along with the conveying chain wheel 10, the cross-grooved wheels 3-1 and the idler wheels 4-1 arranged on the new tea trays also enter the lower layer along with the layer wheels 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 mesh 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 dislocation of the conveying chains at the two sides of the improved device are all designed identically.
Similarly, the swing amplitude of the mesh tea tray is too large when the tail of the whole machine rises due to manufacturing errors, chain tension, long pin shaft strength and the like, and the inventor finds a solution by repeatedly researching and repeatedly testing that an independent circulating chain (called a tail chain for short) is added on the short side of the tail of the whole machine, the tail chain is of the same type as a conveying chain, the length of the tail chain is an integral multiple of the spacing (25 pitches) of the new mesh tea tray, a duckbill structure is arranged on each 25 pitches of the tail chain, the width of the duckbill is slightly larger than the diameter of an idler wheel of the tray, the duckbill is perpendicular to the tail chain, and the duckbill is outwards. The tail chain runs synchronously with the conveying chain through the duckbill transmission chain, the horizontal distance between the tail wheel and the conveying chain wheel at the tail part of the device is equal to the distance (12 pitches) between the fulcrum sleeve hole of the tray and the idler wheel, the tail wheel and the conveying chain wheel are same in mode and teeth, when the new-mesh tea tray idler wheel runs to the lower tail wheel tangentially, the new-mesh tea tray idler wheel is just clamped by the duckbill and runs synchronously with the duckbill, so that the tray cannot swing, and when the new-mesh tea tray idler wheel runs to the upper tail wheel tangentially, the new-mesh tea tray idler wheel breaks away from the duckbill to run respectively. The duckbill is then rotated to the original point of tangency to catch the next new mesh tea tray idler, and so on. As can be seen from fig. 4, the inventors add a tail chain 12 on the short side of the tail of the machine, the tail chain length being an integer multiple of 25 pitches (new mesh tea tray spacing), each 25 pitches being fitted with a duckbill structure 13, the duckbill width being slightly larger than the diameter of tray idler 4-2, the duckbill being perpendicular to the tail chain 12, the duckbill facing outwards. The tail chain 12 moves synchronously with a conveying chain 17 for conveying the new-mesh tea trays through a duckbill drive chain 16, and the duckbill drive 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 trays. The new mesh tea tray idler wheel 4-2 is just caught by the duckbill 13 when running tangent to the tail chain 12 and runs synchronously with the duckbill, so that the new mesh tea tray does not swing when ascending, and is separated from the duckbill when running tangent to the upper tail wheel 18 of the tail chain 12. The duckbill is then rotated to the home point to catch the following mesh tea tray idler 4-2, and so on.
Taking the design of the embodiment as an example, a conveying chain uses C216AH with a pitch of 50.8mm, new mesh tea trays with a length of 3000mm and a width of 1200mm, tea tray intervals (gaps between trays) of 70mm, and a distance between the new mesh tea trays of 25 pitch (1270 mm); the fulcrum sleeve holes are 12 pitches (609.6 mm) from the idler pulley, the span pulley is 130mm from the idler pulley, and the gap width between the conveying guide groove and the idler pulley guide groove is 110mm.
The foregoing is only illustrative of the present invention and is not to be construed as limiting the scope of the invention except as may be modified or practiced in light of the above-described teaching.
