Description

Technical Field

[0001] The utility model relates to the technical field of tea drying equipment, in particular to a right-angle turning mechanism of a tea drying tray. Background Art

[0002] The tea drying tray is generally a square tray with a large projection area when viewed from above. In the automatic tea drying equipment, if the tea drying tray is turned by rounding the corners, a larger space is required to achieve the turning. If the tea drying tray is turned at a right angle, the space required for the turning is smaller.

[0003] The Chinese utility model patent with announcement number CN204384401U discloses a right-angle turning mechanism for a conveyor belt, which discloses that the product flows in from the first conveyor belt, and when the first photoelectric sensing probe detects the product, the roller group runs, and it stops after running for a set time. When the first photoelectric sensing probe detects the next product and starts the roller group again, until the set number of products enter the roller group, the V-belt pulley group runs, and the cylinder drives the roller group to descend at the same time. The product is on the conveyor belt and is conveyed to the second conveyor belt along the conveyor belt. When the second photoelectric sensing probe detects that the same number of products enter the second conveyor belt, the V-belt pulley group stops running, and the cylinder drives the roller group to rise and return to its original position, completing the right-angle turn of the product. The right-angle turning structure disclosed in this patent is relatively complex, and the operation process is also relatively complex. Utility Model Content

[0031] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0032] Please refer to Figures 1 to 7 , the embodiments provided by the utility model are:

[0033] A right-angle turning mechanism for a tea drying tray comprises a first conveying mechanism 1, an end stopper and a right-angle turning mechanism 2. The first conveying mechanism 1 is used to convey the tea drying tray to its end. The end stopper is installed at the end of the first conveying mechanism 1. The end stopper is used to limit the position of the tea drying tray at the end of the first conveying mechanism 1. The right-angle turning mechanism 2 is located at the conveying end position of the first conveying mechanism 1 and is located in front of the end stopper, that is, when the tea drying tray contacts the end stopper, it is just above the right-angle turning mechanism 2. When the tea drying tray is conveyed by the first conveying mechanism 1 until it contacts the end stopper, the right-angle turning mechanism 2 performs a right-angle turning conveyance at the original location.

[0034] The right-angle turning mechanism 2 includes a right-angle turning frame 21, an eccentric lifting mechanism 22 and a direction-changing conveying mechanism 23. The eccentric lifting mechanism 22 includes a lifting motor 221, a lifting shaft 222, two eccentric wheels 223, at least two bare rods 224, at least two sliders 225 and two sliding plates 226. The lifting motor 221 is fixed on the right-angle turning frame 21, and the output shaft of the lifting motor 221 is coaxially fixedly connected with the lifting shaft 222. The two eccentric wheels 223 are symmetrically and eccentrically mounted on the lifting shaft 222. On the rotating shaft 222, the light rods 224 are vertically fixed on the right-angle turn frame 21, each of the light rods 224 is provided with at least one slider 225 that slides up and down, each of the sliding plates 226 is fixedly installed with at least one slider 225, the bottom of one sliding plate 226 rests on one eccentric wheel 223, the direction-changing conveying mechanism 23 is installed on the top of the two sliding plates 226, and the conveying direction of the direction-changing conveying mechanism 23 is perpendicular to the conveying direction of the first conveying mechanism 1. The modular design is adopted, and the direction-changing conveying mechanism 23 is fixed on two vertically placed sliding plates 226. In order to make the sliding plates 226 move up and down, the two eccentric wheels 223 located at the bottom of the sliding plates 226 and in contact with the sliding plates 226 drive the sliding plates 226 to move up and down. The light rod 224 and the slider 225 guide the up and down movement of the sliding plates 226, which is easy to assemble and occupies a small space. In addition, the right-angle turning mechanism 2 is provided with an independent right-angle turning frame 21, so that the right-angle turning mechanism 2 can be assembled independently and is convenient to add at the required place on the assembly line.

[0035] Furthermore, in order to ensure reliable movement between the eccentric wheel 223 and the sliding plate 226, the eccentric lifting mechanism 22 also includes two wear-resistant rings 227, each of which is fixedly sleeved with a wear-resistant ring 227, and the bottom of the sliding plate 226 rests on the wear-resistant ring 227 to enhance the wear resistance between the sliding plate 226 and the eccentric wheel 223.

[0036] Furthermore, each of the eccentric wheels 223 has a limiting flange 2231 extending outward in a circumferential manner on the end face opposite to the other eccentric wheel 223, and the outer side surface of the wear-resistant ring 227 contacts the inner side surface of the limiting flange 2231. The contact position of the sliding plate 226 and the eccentric wheel 223 is limited by the positions of the light rod 224 and the slider 225, and the contact position of the sliding plate 226 and the eccentric wheel 223 is further limited by the limiting flange 2231, thereby ensuring the stability of equipment operation.

[0037] Furthermore, the number of the light rods 224 is 4, the number of the sliders 225 is 8, and four sliders 225 are fixedly mounted on each sliding plate 226. Every two sliders 225 are slidably arranged on the same light rod 224. Then, the number of sliders 225 matched with each sliding plate 226 is 4, and the number of light rods 224 is 2, so that the sliding up and down sliding of the sliding plate 226 is more accurate and stable, and will not be skewed.

[0038] Furthermore, the end stopper is a baffle or a roller. The baffle is easy to install, and the roller can reduce the friction between the tea drying tray and the equipment.

The first belt conveying mechanism 12 is installed on the first frame 11 by adopting a modular design, wherein the first frame 11 is formed by splicing and fixing profile rods in three directions of X, Y and Z.

[0040] Furthermore, the direction-changing conveying mechanism 23 includes a second frame 231 and a second belt conveying mechanism 232, wherein the second belt conveying mechanism 232 is fixed on the second frame 231, and the second belt conveying mechanism 232 includes a second motor 2321, a second rotating shaft 2322, two second belt driving wheels, two second belts 2323 and two second belt driven wheels, wherein the output shaft of the second motor 2321 is fixedly connected to the second rotating shaft 2322, and the two second belt driving wheels are coaxially fixed on the second rotating shaft 2322, and each second belt 2323 has one end sleeved on the second belt driving wheel and the other end sleeved on the second belt driven wheel. The second belt conveying mechanism 232 is installed on the second frame 231 by adopting a modular design, wherein the second frame 231 is formed by splicing and fixing profile rods in the X and Y directions.

[0041] Furthermore, in order to take away the tea drying tray output from the right-angle turning mechanism 2 for further transportation, a third conveying mechanism 3 is also included, the third conveying mechanism 3 is located at the output side of the direction-changing conveying mechanism 23, and the conveying direction of the third conveying mechanism 3 is the same as the conveying direction of the direction-changing conveying mechanism 23. The third conveying mechanism 3 includes a third frame 31 and a third belt conveying mechanism 32, the third belt conveying mechanism 32 is fixed on the third frame 31, the third belt conveying mechanism 32 includes a third motor 321, a third rotating shaft 322, two third belt driving wheels, two third belts 323 and two third belt driven wheels, the output shaft of the third motor 321 is fixedly connected to the third rotating shaft 322, the two third belt driving wheels are coaxially fixed on the third rotating shaft 322, and one end of each of the third belts 323 is sleeved on the third belt driving wheel, and the other end is sleeved on the third belt driven wheel. The third belt conveyor mechanism 32 is installed on the third frame 31 by adopting a modular design, wherein the third frame 31 is formed by splicing and fixing profile rods in three directions of X, Y and Z.

[0042] Preferably, the first conveying mechanism 1 and the third conveying mechanism 3 have exactly the same structure, so that after the equipment is modularly designed, each module has stronger versatility and is easier to install and debug.

[0043] Furthermore, it also includes a side limiter 4, and the first conveying mechanism 1, the direction-changing conveying mechanism 23, and the third conveying mechanism 3 are all equipped with the side limiter 4 on the side parallel to their own conveying direction.

[0044] Furthermore, the side limiter 4 is a baffle or a roller. The baffle is easy to install, and the roller can reduce the friction between the tea drying tray and the equipment. The roller method is preferably used.

[0045] Furthermore, in order to ensure that the first belt 123, the second belt 2323 and the third belt 323 have better performance in conveying the tea drying tray at each position, a plurality of supporting rollers are arranged in the middle of the first belt 123, the second belt 2323 and the third belt 323 to make the conveying more stable and reliable.

[0046] In conjunction with the instruction manual Figure 1 To Attachment Figure 7 The working process of the right-angle turning mechanism of the tea drying tray is as follows: in the first conveying mechanism 1, the first belt conveying mechanism 12 delivers the tea drying tray and when it reaches its own end position, when the tea drying tray contacts the end limit piece, it stops moving forward. At this time, the tea drying tray is just above the right-angle turning mechanism 2; initially, the second belt conveying mechanism 232 of the right-angle turning mechanism 2 is at the lowest position. At this time, the second belt conveying mechanism 232 cannot contact the tea drying tray. When it is detected that the tea drying tray is above the right-angle turning mechanism 2, the lifting motor 221 drives the eccentric wheel 223 to rotate half a circle. At this time, the second belt conveying mechanism 232 is at the highest position and contacts the tea drying tray. The second belt conveying mechanism 232 is started to output the tea drying tray in a direction perpendicular to the first conveying mechanism 1, and docks with the third belt conveying mechanism 32, and is taken away by the third belt conveying mechanism 32 to continue to be transported downward.

[0047] In summary, the right-angle turning mechanism of the tea drying tray provided by the utility model has the following advantages:

[0048] 1. The eccentric wheel 223 cooperates with the slider 225, the polished rod 224 and the sliding plate 226, so that the right-angle turning mechanism 2 can lift the tea drying tray in situ and turn it at a right angle, which occupies a small space, has a clever structure, and is easy to process and install;

[0049] 2. A modular design is adopted to design the first conveying mechanism 1, the right-angle turning mechanism 2, and the third conveying mechanism 3, so as to facilitate batch processing and assembly.
