Description

Technical Field

[0001] This utility model relates to the technical field of tea drying machines, specifically to an anti-caking and turning mechanism for tea drying machines. Background Technology

[0002] Generally speaking, tea refers to a beverage made from the leaves of the tea tree that can be brewed directly with boiling water. Tea drying is a step in the tea-making process. The purpose of drying is to use high temperatures to destroy enzymes, stop enzymatic oxidation, evaporate moisture, and compress the tea leaves, so that the raw tea is fully dried, preventing non-enzymatic oxidation and helping to maintain its quality.

[0003] Existing equipment typically uses horizontal dryers to dry large quantities of tea leaves. Since tea leaves contain a lot of moisture before drying, in order to ensure that the tea leaves do not clump together during the drying process, a motor is usually used to drive the turning teeth to turn the tea leaves, so that the tea leaves can be dried evenly.

[0004] However, since different shapes of tea require different degrees of turning, and the position of the turning teeth in existing devices is usually fixed, smaller tea leaves may not be turned at all when turning different shapes of tea leaves, while larger tea leaves may break. This not only causes the tea leaves to break, but also affects the drying efficiency of the tea leaves. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an anti-caking turning mechanism for tea drying machines, which can solve the existing problems.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A tea drying machine uses an anti-caking turning mechanism, comprising: a drying cylinder with a cover hinged to it; a motor mounted on one side of the drying cylinder; a main shaft at the motor's output end; a turning assembly mounted on the main shaft; the turning assembly including a T-slot on the main shaft; a T-strip on the T-slot; turning teeth on one side of the T-strip; a pull plate on the T-strip; and a locking component on the pull plate; and a bottom scraping assembly mounted on the turning teeth; the bottom scraping assembly including a spring on the turning teeth; a sliding sleeve on the spring; and an arc-shaped plate on the sliding sleeve.

[0008] Furthermore, the material turning assembly also includes four sets of T-shaped grooves evenly distributed around the circumference of the main shaft, with the T-shaped strips movably set inside the T-shaped grooves.

[0009] Furthermore, a pull plate is provided on one side of the T-shaped strip, and a through groove is provided on the T-shaped groove, and the through groove communicates with the T-shaped groove. The pull plate is movably disposed in the through groove.

[0010] Furthermore, the locking component includes a rotating column rotatably mounted on the top of the pull plate away from the main shaft, a connecting plate on the outside of the rotating column, and a torsion spring between the connecting plate and the pull plate, with the torsion spring located on the outside of the rotating column.

[0011] Furthermore, a threaded post is provided on one side of the connecting plate, and the threaded post is threaded on the connecting plate. A threaded hole is provided on the main shaft corresponding to the threaded post, and the threaded hole matches the threaded post.

[0012] Furthermore, the bottom scraping assembly also includes two sets of springs evenly arranged inside the placement groove.

[0013] Furthermore, a telescopic rod is provided between the sliding sleeve and the placement groove, and the telescopic rod is located inside the spring.

[0014] Furthermore, a conical block is provided on one side of the sliding sleeve, and an arc-shaped plate is provided on the end of the turning tooth away from the main shaft, and the arc-shaped plate is in contact with the drying cylinder.

[0015] Compared with the prior art, the beneficial effects of this utility model include:

[0016] 1. By controlling the T-shaped strip to slide in the T-groove, the position of the four sets of turning teeth installed on the main shaft can be adjusted, so that the four sets of turning teeth can be staggered and the spacing of the turning teeth can be adjusted to evenly turn the tea leaves of different shapes, so that the tea leaves can be dried more thoroughly and thus avoid the phenomenon of tea leaves clumping during drying.

[0017] 2. To prevent the tea leaves at the bottom of the drying cylinder from not being turned over when the turning teeth are turning the tea leaves, the spring force keeps the arc plate in contact with the inner wall of the drying cylinder, so that the tea leaves can be turned over more thoroughly. The inclined surface on the conical block prevents the tea leaves from piling up on the turning teeth after turning. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] like Figure 1 - Figure 7 As shown, this utility model provides an anti-caking turning mechanism for a tea drying machine, including: a drying cylinder 1, a cover 3 hinged to the drying cylinder 1, a motor 2 provided on one side of the drying cylinder 1, a main shaft 4 provided at the output end of the motor 2, and also including: a turning component provided on the main shaft 4, the turning component including a T-shaped groove 9 provided on the main shaft 4, a T-shaped strip 6 provided on the T-shaped groove 9, a turning tooth 5 provided on one side of the T-shaped strip 6, a pull plate 7 provided on the T-shaped strip 6, and a locking component provided on the pull plate 7;

[0029] The turning tooth 5 is equipped with a bottom scraping component, which includes a spring 20 on the turning tooth 5, a sliding sleeve 17 on the spring 20, and an arc plate 16 on the sliding sleeve 17.

[0030] In the above scheme:

[0031] 1. By sliding the T-shaped strip 6 within the T-shaped groove 9, it is convenient for staff to arrange the turning teeth 5 in a staggered manner according to the shape of the tea leaves, so as to evenly turn the tea leaves of different shapes.

[0032] 2. When fixing the position of the flipping tooth 5, the position of the flipping tooth 5 can be quickly fixed by the engagement of the threaded post 11 and the threaded hole 10 in the locking component.

[0033] 3. When turning the tea leaves, the elastic force of the spring 20 can drive the sliding sleeve 17 to contact the inner wall of the drying cylinder 1, so that the turning teeth 5 can turn the tea leaves at the bottom of the drying cylinder 1 completely.

[0034] In this embodiment, the cover 3 is semi-circular, one end of the cover is rotatably connected to the drying cylinder 1, the other end of the cover is provided with an assembly block 31, both ends of the cover are provided with rubber sealing strips 32, one side of the drying cylinder is provided with a support strip, the surface of the support strip 33 is provided with an assembly groove 331, the assembly block is inserted into the assembly groove and the two are positioned by bolts.

[0035] In this embodiment, the material turning assembly also includes four sets of T-shaped grooves 9 evenly distributed around the circumference of the main shaft 4, and T-shaped strips 6 are movably disposed in the T-shaped grooves 9.

[0036] In the above scheme, the position of the turning tooth 5 can be adjusted by sliding the T-shaped strip 6 within the T-shaped groove 9.

[0037] In this embodiment, a pull plate 7 is provided on one side of the T-shaped strip 6, and a through groove 8 is provided on the T-shaped groove 9, and the through groove 8 communicates with the T-shaped groove 9. The pull plate 7 is movably disposed in the through groove 8.

[0038] In the above scheme: the setting of the pull plate 7 makes it easy for the staff to control the movement of the T-shaped strip 6, and the setting of the through groove 8 makes it easy for the pull plate 7 to move.

[0039] In this embodiment, the locking component includes a rotating column 13 rotatably disposed on the top of the pull plate 7 away from the main shaft 4, a connecting plate 12 disposed on the outside of the rotating column 13, and a torsion spring 14 disposed between the connecting plate 12 and the pull plate 7. The torsion spring 14 is disposed on the outside of the rotating column 13.

[0040] In the above scheme, the elastic force of the torsion spring 14 can drive the connecting plate 12 to rotate a certain angle when the threaded post 11 disengages from the threaded hole 10 when the position of the flipping tooth 5 needs to be adjusted. This makes it easier for the staff to observe the position of the threaded post 11, thereby making it easier for the staff to quickly adjust the position of the flipping tooth 5.

[0041] In this embodiment, a threaded post 11 is threaded on one side of the connecting plate 12. The threaded post 11 is threaded on the connecting plate 12, and a threaded hole 10 is provided on the spindle 4 corresponding to the threaded post 11. The threaded hole 10 matches the threaded post 11.

[0042] In the above scheme, the fit between the threaded post 11 and the threaded hole 10 facilitates the fixing of the position of the turning tooth 5.

[0043] In this embodiment, the bottom scraping assembly also includes two sets of springs 20 evenly arranged inside the placement groove 18.

[0044] In the above scheme, the placement groove 18 can facilitate the protection of the spring 20.

[0045] In this embodiment, a telescopic rod 19 is provided between the sliding sleeve 17 and the placement groove 18, and the telescopic rod 19 is located inside the spring 20.

[0046] In the above scheme, the telescopic rod 19 is designed to prevent the spring 20 from deforming during operation.

[0047] In this embodiment, a conical block 15 is provided on one side of the sliding sleeve 17, and an arc plate 16 is provided on the end of the turning tooth 5 away from the main shaft 4, and the arc plate 16 is in contact with the drying cylinder 1.

[0048] In the above scheme: the inclination of the conical block 15 can prevent the tea leaves from getting stuck on the sliding sleeve 17 when the sliding sleeve 17 is turning the tea leaves. Through the arc surface of the arc plate 16, the sliding sleeve 17 can be kept in close contact with the inner wall of the drying cylinder 1, thereby achieving full turning of the tea leaves.

[0049] In this embodiment, during the drying of tea leaves, the buckles on the cover 3 are first aligned with the slots on the drying cylinder 1 to secure them, thus connecting the cover 3 and the drying cylinder 1 into a single unit. Then, the heating element inside the drying cylinder 1 is activated, allowing the heat emitted by the heating element to dry the tea leaves. To prevent clumping during drying, the tea leaves need to be turned over to break them up and ensure more even drying. The operator starts the motor 2, which drives the turning teeth 5 to rotate via the main shaft 4. Since different types of tea have different shapes, the operator adjusts the position of the turning teeth 5 according to the specifications of the tea leaves, ensuring that the four sets of turning teeth 5 are arranged in a staggered pattern on the main shaft 4. This ensures that the turning teeth 5 can turn over different types of tea leaves without... Excessive damage to the tea leaves can be caused by improper handling. To prevent this, the operator controls the sliding of the pull plate 7 within the through groove 8, which in turn causes the T-shaped strip 6 to slide within the T-groove 9. This allows the turning teeth 5 to move to a designated position. Then, by controlling the rotation of the connecting plate 12, the operator aligns the threaded column 11 with the threaded hole 10. Next, the operator screws the threaded column 11 into the threaded hole 10, thus locking the position of the turning teeth 5. This ensures the stability of the turning teeth 5 during use. To ensure that the tea leaves at the bottom of the drying cylinder 1 can be turned, the spring force of the spring 20 causes the arc-shaped plate 16 on the sliding sleeve 17 to press tightly against the inner wall of the drying cylinder 1. The conical block 15 prevents the tea leaves from getting stuck on the turning teeth 5 when turning the tea leaves, thus allowing the tea leaves to be turned over completely and improving the turning effect of the turning teeth 5.
