Description

Technical Field

[0001] This utility model relates to the technical field of tea processing equipment, specifically to a stir-frying structure for a tea frying machine. Background Technology

[0002] Tea frying machines are common equipment in tea production. Their main function is to fix the tea leaves and perform preliminary shaping.

[0003] The stirring structure of a tea frying machine directly affects the uniformity of heating and the quality of the tea leaves. In existing tea frying machines, the stirring plate is usually rigidly connected to the drive component, resulting in poor adhesion between the stirring plate and the inner wall of the pot. This easily leads to localized missed stirring, resulting in uneven color and taste of the tea leaves and affecting their quality. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a stir-frying structure for a tea frying machine that can adaptively conform to the pot body, thus solving the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a stir-frying structure for a tea frying machine, including a stir-frying plate and a connecting arm connected to the rotating shaft of the tea frying machine. A connecting rod assembly and a spring are connected between the stir-frying plate and the connecting arm. The connecting rod assembly is used to assist in the stable support of the stir-frying plate. Under the elastic tension of the spring, the stir-frying plate adaptively fits against the inner wall of the pot of the tea frying machine.

[0006] Preferably, the linkage assembly includes a first link, a second link, and a third link, with one end of the first link and the second link respectively rotatably connected to different positions of the connecting arm, and the other end of the first link and the second link rotatably connected to both ends of the third link.

[0007] Preferably, the end of the second connecting rod away from the connecting arm is fixedly connected to the first extension, and the stir-fry plate is fixedly connected to the first extension. The end of the second connecting rod near the connecting arm is fixedly connected to the second extension. One end of the spring is fixedly connected to the connecting arm, and the other end of the spring is fixedly connected to the second extension. The spring pulls the second connecting rod so that the stir-fry plate is always in contact with the inner wall of the pot.

[0008] Preferably, the rotatable connections between the first link and the connecting arm, the second link and the connecting arm, the first link and the third link, and the second link and the third link are all achieved by bolts, nuts, and self-lubricating washers.

[0009] Preferably, a plate-shaped connector is fixedly connected to the second extension of the second connecting rod. The connector has a circular through hole, and the hook at one end of the spring passes through the through hole and is fixed to the second connecting rod. The hook at the other end of the spring is connected to the connecting arm rotatably via a bolt on the first connecting rod.

[0010] Preferably, a stirring rod is fixedly connected to the third connecting rod, and when the frying plate is in contact with the pot body, the stirring rod is located behind the frying plate in the direction of rotation of the frying plate, which can disperse the tea leaves scooped up by the frying plate backward.

[0011] Preferably, the number of stirring rods is set to two, and the rods of the two stirring rods are parallel to each other and fit together.

[0012] This utility model provides a stirring structure for a tea frying machine. It has the following beneficial effects: 1. The frying structure of this tea frying machine, through the elastic tension of the spring on the second connecting rod, combined with the supporting effect of the connecting rod assembly, allows the frying plate to adaptively adjust its angle according to the curvature of the inner wall of the pot, always maintaining a tight fit, avoiding missed frying, and improving the quality of the tea.

[0013] 2. The frying structure of this tea frying machine adopts a multi-bar rotating connection structure of the first link, the second link and the third link through the linkage assembly, which ensures the flexible adjustment space of the frying plate.

[0014] 3. The tea-frying machine's stirring structure, with the stirring rod on the third connecting rod located behind the frying plate, can promptly disperse the tea leaves scooped up by the frying plate, preventing them from piling up and further improving the uniformity of heating; the parallel and close arrangement of the two stirring rods enhances the dispersion effect.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] This utility model embodiment provides a stirring structure for a tea frying machine, such as... Figures 1 to 3 As shown, it includes a stir plate 1, a stirring rod 2, a connecting arm 3, a spring 4, a first connecting rod 5, a second connecting rod 6, a third connecting rod 7, and a connecting piece 8.

[0019] Connecting arm 3: One end is fixedly connected to the rotating shaft of the tea frying machine and rotates synchronously with the rotating shaft to provide driving force for the entire frying structure; Linkage assembly: Composed of first link 5, second link 6, and third link 7. One end of the first link 5 is rotatably connected to the upper part of the connecting arm 3 via bolts, nuts, and self-lubricating washers, and the other end is rotatably connected to the left end of the third link 7 in the same manner; one end of the second link 6 is rotatably connected to the lower part of the connecting arm 3 via bolts, nuts, and self-lubricating washers, and the other end is rotatably connected to the right end of the third link 7 in the same manner, forming a four-bar linkage structure to ensure the stability of the stir-fry plate 1 during adjustment. Stirring plate 1 and extension: The end of the second connecting rod 6 away from the connecting arm 3, that is, the end connected to the third connecting rod 7, is integrally formed with a first extension. The stirring plate 1 is fixed to the first extension by welding or bolting, and the angle of contact with the pot body is adjusted with the swing of the second connecting rod 6. The end of the second connecting rod 6 near the connecting arm 3 is integrally formed with a second extension, which is used to connect the spring 4. Spring 4: Spring 4 is a tension spring. One end of the hook passes through the circular through hole of the connector 8 on the second extension and locks in place. The other end of the hook is hooked onto the bolt that rotatably connects the first connecting rod 5 and the connecting arm 3. The bolt end is equipped with a limiting structure to prevent it from falling off. The tension of spring 4 continuously pulls the second extension, causing the second connecting rod 6 to drive the stir-fry plate 1 to always keep it in contact with the inner wall of the pot. Stirring rod 2: Two stirring rods 2 are welded parallel and close together on the third connecting rod 7. Their positions correspond to the rear of the frying plate 1 along the rotation axis. That is, when the frying plate 1 scoops up the tea leaves forward, the stirring rod 2 moves synchronously with the third connecting rod 7 to the tea leaf accumulation area. The rod body disperses the accumulated tea leaves backward to ensure uniform heating.

[0020] Working principle: During operation, the rotating shaft drives the connecting arm 3 to rotate, and the connecting rod assembly moves synchronously with the connecting arm 3. Under the tension of the spring 4 and the support of the connecting rod assembly, the frying plate 1 adheres to the inner wall of the pot to stir-fry the tea leaves. At the same time, the stirring rod 2 moves with the third connecting rod 7 to disperse the tea leaves scooped up by the frying plate 1, thereby achieving efficient and uniform tea frying.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
