Description

Technical Field

[0001] The utility model relates to the field of food processing, in particular to a tea stripping machine. Background Art

[0002] An existing tea leaf straightening machine includes a frame, a heating assembly, and a movable mechanism disposed on the frame for transverse reciprocation. The movable mechanism includes a base and a wok, and the base drives the wok to move synchronously, thereby enabling the movable mechanism to perform transverse reciprocating movement relative to the frame. The front edge of the wok is swingably connected to the front portion of the base via a rotating shaft. A retractable cylinder is disposed between the rear edge of the wok and the rear edge of the base. The cylinder retracts and contracts to drive the rear edge of the wok to swing upward about the rotating shaft. At this time, the cylinder is exposed in an opening formed between the rear edge of the wok and the front edge of the base. As the rear edge of the wok swings forward, a portion of the cylinder is exposed above the heating assembly. This causes the cylinder to deform due to thermal expansion and contraction, affecting the smoothness of its expansion and contraction. Excessive cylinder temperature can also affect its airtightness, resulting in the cylinder being unable to stably retract and retract, shortening its service life and affecting the user experience. Utility Model Content

[0003] In order to solve the shortcomings of the existing technology, the utility model provides a tea strip sorting machine, in which the telescopic component is arranged between the corresponding side edges of the frying pan and the base and vertically avoids the heating component, ensuring the reliable operation of the telescopic component, extending the service life and improving the user experience.

[0004] The utility model is realized in the following manner: a tea stripping machine, comprising a frame, a heating component, and a movable mechanism that can be reciprocated laterally on the frame, the movable mechanism comprising a base and a wok, the front edge of the wok being swingably connected to the front portion of the base via a rotating shaft, a telescopic component being provided between the corresponding side edges of the base and the wok, the first end of the telescopic component being connected to the front portion of the side edge of the base, and the second end being connected to the middle and rear portion of the side edge of the wok, so that the vertical projections of the telescopic component and the heating component are mutually offset. The first end of the telescopic component is connected to the front portion of the side edge of the base, and the second end is connected to the middle and rear portion of the side edge of the wok, ensuring that the vertical projections of the telescopic component and the heating component are mutually offset, effectively preventing the heat generated by the heating component from being transferred to the telescopic component, effectively reducing the deformation of the telescopic component due to thermal expansion and contraction, ensuring the normal telescopic operation of the telescopic component, and ensuring the internal airtightness of the telescopic component, ensuring that the telescopic accuracy meets the use requirements, reducing the maintenance cost by reducing the failure rate, and improving the reliability of use.

[0005] Preferably, the telescopic assembly is a linearly retractable cylinder. By telescoping, the distance between its first and second ends is adjusted, allowing the wok to swing about the rotating shaft between a horizontal frying position and an inclined discharge position. The cylinder not only allows the wok to swing between the horizontal and inclined discharge positions by telescoping, but also provides convenient access to an air source for driving, thereby facilitating precise control of the wok's movements. When the wok is in the horizontal frying position, the tea leaves are evenly spread across the wok, ensuring they remain in their designated area and are fully fryable. When the wok is in the inclined discharge position, the tea leaves slide forward along the sorting groove, clearing the space for subsequent processing and enabling continuous batch processing. Furthermore, when the wok is switched to the inclined discharge position, the rear edge of the wok separates from the base, creating an opening. Heat is then collected upward and released through the opening. The telescopic assembly is positioned at the front of the base, away from the opening, to prevent a significant temperature rise from excessive heat exposure and ensure reliable operation within a preset temperature range.

[0006] Preferably, the vertical projections of the first and second ends are offset so that when the wok is switched to the horizontal frying position, it abuts the top surface of the base, leaving space for accommodating the telescopic assembly. When the wok is in the horizontal frying position, it abuts the top surface of the base, and the vertical height difference between the first and second ends of the telescopic assembly is small. By staggering the first and second ends, space is provided for the telescopic assembly, ensuring that the telescopic assembly can be retracted to bridge the gap between the wok and the base.

[0007] Preferably, a lower connecting ear is provided at the front side edge of the top surface of the base, and the first end of the telescopic assembly is rotatably connected to the lower connecting ear. The first end of the telescopic assembly is rotatably connected to the lower connecting ear via a connecting shaft. This not only ensures that the telescopic assembly can transmit force to the base through telescopic changes, thereby ensuring that the relative position between the wok and the base can be adjusted, but also enables the rotatable connection between the telescopic assembly and the base via the connecting shaft, thereby allowing the angle between the telescopic assembly and the base to be adjusted, thereby offsetting deviation caused by non-concentric rotation of the wok and the telescopic assembly.

[0008] Preferably, the side edge of the wok extends obliquely outward to form an extended edge, with an upper connecting ear positioned in the middle of the extended edge. The second end of the telescopic assembly is rotatably connected to the upper connecting ear. The upwardly angled extension not only serves to receive tea leaves and guide them into the sorting trough, but also increases the horizontal distance between the telescopic assembly and the sorting trough, thereby increasing the distance between the telescopic assembly and the heating assembly, preventing the heating assembly from affecting the normal operation of the telescopic assembly.

[0009] Preferably, the heating assembly is positioned at the top of the frame. When the wok is switched to the horizontal stir-frying position, it completely covers the heating assembly, ensuring uniform heating of all areas of the wok's bottom surface. Positioning the heating assembly at the top of the frame facilitates heating the wok without adding weight, thereby reducing the load requirements on the telescopic assembly. The heating assembly is located below the wok and applies uniform heat to each tea trough, ensuring a uniform temperature within each trough and consistent tea quality.

[0010] Preferably, the heating assembly is a plurality of electric heating tubes arranged transversely and closely spaced in a front-to-back direction. When the heating tubes are energized, heat is generated, and the heat is transferred upward to heat the tea leaves in the wok.

[0011] The wok's top surface preferably includes several tea-leaf sorting grooves arranged in a front-to-back direction and closely spaced laterally. The front ends of these tea-leaf sorting grooves are equipped with discharge openings with door panels. These door panels can be opened when the wok is switched to the tilted discharge position to allow the roasted tea leaves to be discharged through the discharge openings. The tea-leaf sorting grooves receive and roast the tea leaves into tea strips. When the wok is switched to the tilted discharge position, the roasted tea leaves slide forward along the tea-leaf sorting grooves and are collected and transferred before passing through the opened discharge openings.

[0012] Preferably, the telescopic components are in two groups and are separately arranged on both sides of the base. The telescopic components are separately arranged on both sides of the wok to ensure that the wok swings smoothly and switches between different working positions.

[0013] Preferably, a guide assembly is provided between the base and the frame to guide the lateral reciprocating movement thereof, and the wok reciprocates laterally synchronously with the base. The frame is provided with a drive mechanism for driving the lateral reciprocating movement of the base. The guide assembly guides the base for lateral reciprocating movement along a predetermined path to prevent the base from deflecting. The drive mechanism is configured to drive the base for lateral reciprocating movement to ensure that the tea leaves can be rolled and curled into strips within the front-to-back striping grooves.

[0014] The beneficial effects of the present invention are as follows: the first end of the telescopic component is connected to the front side edge of the base, and the second end is connected to the middle and rear side edge of the wok, ensuring that the vertical projections of the telescopic component and the heating component are staggered with each other, effectively preventing the heat generated by the heating component from being transferred to the telescopic component, effectively reducing the deformation of the telescopic component due to thermal expansion and contraction, ensuring the normal telescopic operation of the telescopic component, and ensuring the internal airtightness of the telescopic component, ensuring that the telescopic accuracy meets the use requirements, reducing maintenance costs by reducing the failure rate, and improving the reliability of use.

[0018] The essential features of the present invention will be further described below with reference to the accompanying drawings and specific implementation methods.

[0019] like Figure 1 The tea leaf straightening machine shown in the figure comprises a frame 1, a heating assembly 4, and a movable mechanism disposed on the frame 1 for transverse reciprocation. The movable mechanism includes a base 2 and a wok 3. The front edge of the wok 3 is swingably connected to the front portion of the base 2 via a rotating shaft 5. A telescopic assembly 6 is disposed between the corresponding side edges of the base 2 and the wok 3. The first end 7 of the telescopic assembly 6 is connected to the front side edge of the base 2, and the second end 8 is connected to the middle and rear side edge of the wok 3, so that the vertical projections of the telescopic assembly 6 and the heating assembly 4 are offset from each other. The first end 7 of the telescopic assembly 6 is connected to the front side edge of the base 2, and the second end 8 is connected to the middle and rear side edge of the wok 3, ensuring that the vertical projections of the telescopic assembly 6 and the heating assembly 4 are offset from each other. This effectively prevents heat generated by the heating assembly 4 from being transferred to the telescopic assembly 6, effectively reducing deformation of the telescopic assembly 6 due to thermal expansion and contraction, ensuring normal telescopic operation of the telescopic assembly 6, and ensuring that the internal airtightness of the telescopic assembly 6 meets the required telescopic accuracy. By reducing the failure rate, maintenance costs are reduced and reliability is improved.

[0020] In actual operation, the telescopic assembly 6 adjusts the distance between the first end 7 and the second end 8 by telescoping, so that the wok 3 can swing between the horizontal frying position and the inclined discharge position about the rotating shaft 5. Specifically, the first end 7 of the telescopic assembly 6 is connected to the lower connecting ear on the base 2, and the second end 8 is connected to the upper connecting ear on the wok 3. The lower connecting seat is fixed relative to the base 2, and the upper connecting seat swings about the rotating shaft 5. The distance between the upper and lower connecting seats changes in conjunction with the swing angle of the wok 3, so that the angle of the wok 3 can be controlled by adjusting the distance between the upper and lower connecting seats by the telescopic assembly 6.

[0021] In actual operation, the vertical projections of the first end 7 and the second end 8 are offset so that when the wok 3 is switched to the horizontal frying position, it abuts against the top surface of the base 2, leaving space for accommodating the telescopic assembly 6. When the wok 3 is in the horizontal frying position, it is horizontal, ensuring that the tea leaves are evenly distributed within the tea-strip sorting groove 11. At this time, the distance between the upper and lower connecting ears is small, and the telescopic assembly 6 is in a retracted state. The upper and lower connecting ears are respectively located in the middle of the side edge of the wok 3 and the front of the side edge of the base 2 near the rotating shaft 5, providing space for the installation of the telescopic assembly 6.

[0022] In actual operation, when the wok 3 is in the inclined discharging position, the rear edge of the wok 3 is lifted upward and swung and adjusted as the center of the rotating shaft 5, so that the tea leaves can slide along the sorting groove 11 and be discharged out through the discharge port. At this time, the distance between the upper connecting ear and the lower connecting ear increases, and the telescopic component 6 is in an extended state, ensuring that the wok 3 can be pushed to the inclined discharging position. The angle between the wok 3 and the base 2 is preferably 40°-60°. By reducing the change range of the distance between the upper connecting ear and the lower connecting ear, the telescopic parameter requirements of the telescopic component 6 are reduced, thereby reducing the component cost, and ensuring that the tea leaves can be combed and slid along the sorting groove 11, which is convenient for discharging and ensures normal production.

[0023] In actual operation, since the heat generated by the heating component 4 will carry the air and diffuse upward, when the wok 3 is in the inclined discharge position, the rear edge of the wok 3 is lifted and forms an exposed opening with the rear edge of the base 2. The heat generated by the heating component 4 will diffuse from front to back along the inclined bottom surface of the wok 3, ensuring that the heat is away from the telescopic component 6 and ensuring that the telescopic component 6 maintains normal operation within the preset temperature range.

[0024] In actual operation, the telescopic assembly 6 is a linearly retractable cylinder, which is convenient to use and easy to disassemble and maintain. In addition, the telescopic assembly 6 can be an electrically driven mechanical structure, which should also be regarded as a specific embodiment of the present invention.

[0025] In actual operation, a lower connecting ear is provided at the front edge of the top side of the base 2, and the first end 7 of the telescopic assembly 6 is rotatably connected to the lower connecting ear. The lower connecting ear and the first end 7 are both provided with corresponding connecting holes. The connecting holes are aligned and rotatably connected via a connecting shaft, ensuring that the angle between the first end 7 and the lower connecting ear is adjustable and maintains an effective connection at all times.

[0026] In actual operation, the side edge of the wok 3 extends obliquely outward to form an extended edge 9, and an upper connecting ear is provided in the middle of the extended edge 9, and the second end 8 of the telescopic assembly 6 is rotatably connected to the upper connecting ear. The upper connecting ear and the second end 8 are both provided with corresponding connecting holes, which are aligned and rotatably connected by a connecting shaft to ensure that the angle between the second end 8 and the upper connecting ear is adjustable and always maintains an effective connection. The extended edge 9 is formed by the oblique upward extension of the side edge of the wok 3. It is used to connect the wok 3 and the telescopic assembly 6, and to increase the horizontal distance between the telescopic assembly 6 and the wok 3 to move away from the heating assembly 4, thereby reducing the influence of the heating assembly 4 on the telescopic assembly 6. It also plays a guiding role for the tea leaves, ensuring that the tea leaves can smoothly fall into the strip sorting groove 11, and preventing the tea leaves from falling outside the wok 3.

[0027] In actual operation, the heating assembly 4 is positioned atop the frame 1. The wok 3 is switched to the horizontal frying position and completely covers the heating assembly 4, ensuring uniform heating of all areas of the wok 3's bottom surface. The heating assembly 4 comprises a plurality of horizontally arranged electric heating tubes 10, closely spaced front-to-back. When energized, the heat generated by the heating tubes 10 is transferred upward and uniformly heats all areas of the wok 3 before passing through the base 2. This ensures uniform heating of the wok 3 during its horizontal reciprocating motion, effectively reducing the weight of the movable mechanism and thereby minimizing the requirements for the guide assembly and drive mechanism. Furthermore, the heating assembly 4 can also be positioned on the base 2 or on the bottom of the wok 3, both of which should be considered specific embodiments of the present invention.

[0028] In actual operation, the top surface of the wok 3 is provided with a plurality of strip sorting grooves 11 arranged in a front-to-back direction and closely arranged laterally. The front end of the strip sorting groove 11 is provided with a discharge port with a door panel. The door panel can be opened when the wok 3 is switched to the inclined discharge position so that the fried tea leaves can be discharged through the discharge port. It ensures that the door panel can be closed when the wok 3 is in the horizontal frying position to prevent the tea leaves from escaping from the strip sorting groove 11, and also ensures that the door panel can be opened when the wok 3 is in the inclined discharge position to facilitate the tea leaves to slide out of the strip sorting groove 11.

[0029] In actual operation, the telescopic components 6 are divided into two groups and are placed on both sides of the base 2 (such as Figure 2 As shown), and they operate synchronously, which is convenient for control and ensures that the wok 3 can swing smoothly.

[0030] In actual operation, a guide assembly is provided between the base 2 and the frame 1 to guide their lateral reciprocating movement. The wok 3 reciprocates laterally in tandem with the base 2, and the frame 1 is provided with a drive mechanism to drive the base 2's lateral reciprocating movement. The guide assembly guides the movable mechanism, while the drive mechanism provides driving force, ensuring that the movable mechanism can reciprocate along a predetermined path, thereby tumbling and curling the tea leaves using the U-shaped tea-strip trough 11.
