Description

Technical Field

[0001] This utility model belongs to the field of tea processing technology, and in particular relates to a rapid cooling and spreading device for tea. Background Technology

[0002] Tea leaves refer to the leaves and buds of the tea tree, generally referring to the leaves of the evergreen shrub tea tree that can be used to make tea, as well as the beverage made from these leaves. Tea processing is a complex and delicate process of transforming fresh tea leaves into drinkable tea. The main steps include withering, fixing, rolling, fermentation, and drying. After the tea leaves are dried, they generally need to be cooled using a cooling device to accelerate the cooling down of the hot tea leaves.

[0003] A search revealed CN222264255U, filed on May 21, 2024, which discloses a tea cooling device for easily separating tea dust, relating to the field of tea processing technology. The device includes a tea-spreading sieve with a mechanism for rapid heat dissipation of the tea leaves connected in the middle. This tea cooling device for easily separating tea dust utilizes a central support penetrating the interior of the sieve, with a motor fixedly installed above it. The motor drives a fan and a rotating rod to rotate. Connecting rods and rings are irregularly installed below the rotating rod. When the fan and rotating rod rotate, the fan circulates air above the sieve, promoting rapid heat dissipation of the tea leaves. This heat dissipation method helps maintain the tea's flavor. Furthermore, the rotation of the connecting rod and rings spreads the tea leaves inside the sieve, breaking up any accumulated tea leaves and dissipating internal heat, achieving a cooling effect while maintaining the tea's flavor and color.

[0004] However, it still has the following drawbacks in practical use:

[0005] 1. Existing rapid cooling and spreading devices for tea use a rotating ring to disperse the tea leaves. However, this method causes the tea leaves to come into direct contact with the ring, which can easily damage the tea leaves and affect product quality.

[0006] 2. Existing rapid tea cooling devices use a tea-spreading sieve mounted on the outer wall of a central support. However, this method hinders the rapid removal and processing of tea leaves from the sieve, impacting work efficiency. Therefore, we provide a rapid tea cooling device to address these issues. Summary of the Invention

[0007] The purpose of this invention is to provide a rapid cooling and spreading device for tea leaves. By setting up a buffer component and a striking component, the striking rod can continuously strike the tea spreading sieve, causing the tea leaves to spread out. The large vibration amplitude of the tea spreading sieve can accelerate the cooling and heat dissipation efficiency of the tea leaves without causing damage to the tea leaves or affecting product quality. In addition, the spring uses a buffer protection function for the lifting frame, increasing the service life of the lifting frame. Furthermore, the use of a limiting component facilitates quick assembly and disassembly of the tea spreading sieve, which is beneficial for processing tea leaves, saving time and effort, and increasing work efficiency.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0009] This utility model is a tea rapid cooling and spreading device, including a support frame and a vertical frame installed on its upper surface. A lifting frame is provided directly above the support frame. Fixed plates are fixed at both ends of the front end face of the vertical frame. Slide grooves are provided at the front and rear ends of the inner wall of the fixed plates. Buffer components are provided inside the slide grooves. A striking component is provided below the front end face of the vertical frame. A limit component is provided at the bottom rear end of the lifting frame.

[0010] The buffer assembly includes a guide rod fixed to the inner wall of the chute, and springs sleeved above and below the outer wall of the guide rod;

[0011] The striking assembly includes a motor mounted on the rear end face of the vertical frame, and a drive sprocket mounted on the output shaft of the motor, with driven sprockets at both ends of the drive sprocket;

[0012] The limiting assembly includes an L-shaped locking plate located at the lower rear end of the lifting frame, and a rotating rod fixed above the L-shaped locking plate by a connecting block.

[0013] The present invention is further configured such that a heat dissipation component is provided above the front end face of the vertical frame, and sliders are fixedly provided at the front and rear ends of both sides of the lifting frame, and the sliders are slidably sleeved on the middle of the outer wall of the guide rod.

[0014] The present invention is further configured such that a tea-spreading sieve is slidably inserted into the inside of the lifting frame, and a triangular block is fixedly provided at the bottom rear end of the tea-spreading sieve.

[0015] The present invention is further configured such that chains are fitted on the outer walls of the driving sprocket and the two driven sprockets, and a rotating shaft is fixed at the center of the front end face of the driven sprocket.

[0016] The present invention is further configured such that the front end of the rotating shaft passes through the bearing on the vertical frame and is connected to the disc, and a connecting rod is rotatably installed on the outer side of the front end face of the disc, and the other end of the connecting rod is movably connected to the striking rod through a hinge.

[0017] The present invention is further configured such that the outer wall of the striking rod is slidably sleeved on the inner wall of the sliding sleeve, and a T-shaped rod is fixed between two adjacent sliding sleeves on the left and right sides, with the rear end of the T-shaped rod fixed on the front end face of the vertical frame.

[0018] The present invention is further configured such that a torsion spring is sleeved on the outer wall of the rotating rod, and the two ends of the rotating rod are rotatably installed in bearings on adjacent side plates, and the top of the side plates is fixed to the bottom of the lifting frame.

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model, by setting up a buffer component and a striking component, allows the motor to drive the striking rod to continuously reciprocate up and down, thereby continuously impacting the tea spreading sieve, causing the tea leaves to spread out. The large vibration amplitude of the tea spreading sieve can accelerate the cooling and heat dissipation of the tea leaves without causing damage to the tea leaves or affecting product quality. In addition, the elasticity of the spring can also buffer and protect the lifting frame, increasing the service life of the lifting frame. This solves the problem that existing tea rapid cooling and spreading devices use a rotating ring to disperse the tea leaves, which directly contacts the ring and easily causes damage to the tea leaves, affecting product quality.

[0021] This invention, by setting a limiting component, allows the L-shaped card plate to rotate around the rotating rod under the elastic action of the torsion spring, thereby achieving or releasing the limiting effect between the L-shaped card plate and the triangular block. This facilitates quick assembly and disassembly of the tea spreading sieve, which is beneficial for processing tea leaves and has high work efficiency. It solves the problem that in existing rapid tea cooling devices, the tea spreading sieve is fitted onto the outer wall of the central support, which makes it difficult to quickly remove and process the tea leaves inside the sieve, thus affecting work efficiency.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1

[0033] Please see Figures 1 to 5 This utility model is a tea rapid cooling and spreading device, including a support frame 100 and a vertical frame 101 installed on its upper surface. A lifting frame 103 is provided directly above the support frame 100. Fixed plates 105 are fixed at both ends of the front end face of the vertical frame 101. Slide grooves 105a are provided at both the front and rear ends of the inner wall of the fixed plate 105. A buffer component 200 is provided inside the slide groove 105a. A striking component 300 is provided below the front end face of the vertical frame 101. The buffer component 200 includes a guide rod 201 fixed on the inner wall of the slide groove 105a and springs 202 sleeved on the upper and lower outer walls of the guide rod 201. The striking component 300 includes a motor 301 installed on the rear end face of the vertical frame 101 and a drive sprocket 302 installed on the output shaft of the motor 301. Driven sprockets 304a are provided at both ends of the drive sprocket 302.

[0034] Specifically, a heat dissipation component 102 is provided above the front end face of the vertical frame 101; sliders 103a are fixedly provided at the front and rear ends of both side walls of the lifting frame 103, and the sliders 103a are slidably sleeved on the middle of the outer wall of the guide rod 201; a tea spreading sieve 104 is slidably inserted into the inside of the lifting frame 103, and a triangular block 104a is fixedly provided at the bottom rear end of the tea spreading sieve 104; a chain 303 is sleeved on the outer wall of the driving sprocket 302 and the two driven sprockets 304a, and the front end face of the driven sprockets 304a is... A rotating shaft 304 is fixed at the center position; the front end of the rotating shaft 304 passes through the bearing on the vertical frame 101 and is connected to the disc 305. A connecting rod 306 is rotatably installed on the outer side of the front end face of the disc 305. The other end of the connecting rod 306 is movably connected to the striking rod 307 through a hinge. The outer wall of the striking rod 307 is slidably sleeved on the inner wall of the sliding sleeve 308. A T-shaped rod 308a is fixed between two adjacent sliding sleeves 308 on the left and right sides. The rear end of the T-shaped rod 308a is fixed on the front end face of the vertical frame 101.

[0035] Furthermore, the heat dissipation component 102 is existing technology and will not be described in detail here. The tea spreading sieve 104 is slidably inserted into the lifting frame 103. The guide rod 201 plays a role in limiting and guiding the spring 202. The driving sprocket 302 and the two driven sprockets 304a are connected by the chain 303 to achieve synchronous movement. The slider 103a is slidably installed on the outer wall of the guide rod 201 and, during the up and down movement, squeezes the upper or lower spring 202 to play a buffering role. One end of the connecting rod 306 is rotatably installed on the outer end of the surface of the disc 305, and the other end is movably connected to the striking rod 307 to play a role in connecting and transmitting. The T-shaped rod 308a plays a supporting role for the two sliding sleeves 308.

[0036] The operation process of this embodiment is as follows: After the tea-spreading sieve 104 containing tea leaves is slidably inserted into the lifting frame 103, the heat dissipation component 102 is used to quickly dissipate heat and cool the tea leaves. Then, the motor 301 is started. The output shaft of the motor 301 rotates, driving the drive sprocket 302 to rotate. The drive sprocket 302 and the driven sprockets 304a on both sides are connected and driven by the chain 303. Therefore, when the drive sprocket 302 rotates, it will drive the two driven sprockets 304a to rotate synchronously under the action of the chain 303. The rotation of the driven sprockets 304a will drive the rotating shaft 304 and the disc 305 at its end to rotate. A connecting rod 306 is movably connected to the outer surface of the disc 305. The end of the connecting rod 306 is connected to the hinge. The striking rod 307 is movably connected and slidably installed inside the sliding sleeve 308. As the connecting rod 306 moves in a circular motion with the disc 305, it drives the striking rod 307 to continuously move up and down, which in turn continuously impacts the lifting frame 103 above it. This causes the tea leaves in the tea spreading sieve 104 to vibrate and spread out. The large vibration amplitude of the tea spreading sieve can accelerate the cooling and heat dissipation of the tea leaves without causing damage to the tea leaves and affecting product quality. When the lifting frame 103 is subjected to force, it will drive the slider 103a to move along the guide rod 201 and compress the spring 202. Under the elastic action of the spring 202, the lifting frame 103 can play a buffering and protective role, increasing the service life of the lifting frame 103.

[0037] Example 2

[0038] Please see Figure 3 and Figure 6 Based on Embodiment 1, the difference from the first embodiment is that a limiting component 400 is provided. The limiting component 400 includes an L-shaped card plate 401 located at the rear end below the lifting frame 103, and a rotating rod 402 fixed above the L-shaped card plate 401 by a connecting block. This solves the problem that in the existing tea rapid cooling and spreading device, the tea spreading sieve is sleeved on the outer wall of the central support, which makes it impossible to quickly remove and process the tea in the tea spreading sieve, thus affecting work efficiency.

[0039] Specifically, a torsion spring 403 is sleeved on the outer wall of the rotating rod 402, and the two ends of the rotating rod 402 are rotatably installed in the bearings on the adjacent side plate 404. The top of the side plate 404 is fixed to the bottom of the lifting frame 103.

[0040] Furthermore, the L-shaped clamping plate 401 can rotate around the rotating rod 402 under the elastic action of the torsion spring 403. The L-shaped clamping plate 401 and the triangular block 104a can be used to disassemble and assemble the tea sieve 104.

[0041] The operation process of this embodiment is as follows: After the tea leaves in the tea-spreading sieve 104 have cooled, push the L-shaped clamping plate 401 upward. The rear end of the L-shaped clamping plate 401 moves upward under force. At this time, the L-shaped clamping plate 401 rotates around the rotating rod 402 and squeezes the torsion spring 403. Therefore, the L-shaped clamping plate 401 can contact the limiting effect of the triangular block 104a at the bottom of the tea-spreading sieve 104. Then, the tea-spreading sieve 104 in the lifting frame 103 can be pulled out and the tea leaves inside can be processed. When installing a new tea-spreading sieve 104, simply slide the tea-spreading sieve 104 into the lifting frame 103. During this process, the L-shaped clamping plate 401 will directly clamp on the outside of the triangular block 104a, playing a limiting role and completing the installation. This makes it easier for workers to quickly disassemble and assemble the tea-spreading sieve 104, which is beneficial for processing tea leaves, saving time and effort, and increasing work efficiency.
