Description

Technical Field

[0001] This invention relates to the field of tea sieving technology, specifically to a tea packaging sieving device. Background Technology

[0002] Tea packaging sieving devices are equipment used to sieve and clean tea leaves during the tea processing process. Their main uses include: 1. Grading tea leaves according to their size, shape, or quality for subsequent packaging and sales; 2. Removing impurities such as tea stems, broken leaves, and dust from the tea leaves, thereby improving the purity and quality of the tea.

[0003] During tea processing, due to the effects of picking, transportation, and storage, clay, dust, or other impurities may indeed adhere to the tea leaves. These adhering substances are usually tightly attached to the surface of the tea leaves, and ordinary sieving and shaking methods are often difficult to remove them effectively, which is not conducive to improving the quality of the sieved tea.

[0004] Based on this, a tea packaging screening device is now provided, which can eliminate the drawbacks of existing devices. Summary of the Invention

[0005] To address the aforementioned problems, a tea packaging sieving device is provided, which solves the problem of removing adhering impurities that is difficult to achieve with conventional sieving methods by using a shaking mechanism.

[0006] To address the problems of existing technologies, the present invention provides a tea packaging screening device, including a shaking box, a debris removal box below the shaking box, a feeding trough at the upper end of the shaking box, and a transport device below the debris removal box; The shaking box is equipped with a shaking mechanism for shaking off debris adhering to the tea leaves; The debris removal box is equipped with a slag removal mechanism for screening particles; Below the slag removal mechanism is a collection mechanism for collecting the debris that has been removed; Above the slag removal mechanism is a heating mechanism for heating and a conveying and drying mechanism for conveying heat.

[0007] Preferably, the shaking mechanism includes a fixed plate fixedly installed on the inner wall of the debris removal box, a drive motor installed on the fixed plate, a connecting shaft connected to the output end of the drive motor, a lead screw connected to the other end of the connecting shaft, and a lead screw rotatably engaged with the inner wall of the shaking box. Guide rods are symmetrically arranged in the shaking box and the discharge port, and sliding seats are slidably provided on both the guide rods and the lead screw. An installation block is provided at one end of the sliding seat near the inner wall of the shaking box, and a roller that slidably engages with the inner wall of the shaking box is rolled on the installation block. A spiral screen cylinder sidewall is fixedly installed between the sliding seats. Sliding cylinders are provided at both the upper and lower ends of the spiral screen cylinder, and the inner wall of the upper sliding cylinder slidably engages with the outer wall of the feed trough.

[0008] Preferably, the slag removal mechanism includes a slag removal cylinder, the outer wall of the sliding cylinder at the lower end is slidably fitted with the inner wall of the upper end of the slag removal cylinder, the slag removal cylinder is rotatably disposed inside the slag collection cylinder, the slag collection cylinder is fixedly mounted on a support frame, the support frame is fixedly disposed on the inner wall of the discharge port, the surface of the slag removal cylinder in contact with the slag collection cylinder is provided with a plurality of filter holes, and pulleys are provided on both the lead screw and the outer wall of the upper end of the slag removal cylinder, and a synchronous belt is sleeved between the pulleys.

[0009] Preferably, the collecting mechanism includes a guide port and a collecting frame, a gap is provided between the slag collecting cylinder and the bottom wall of the slag removing cylinder, a guide port is provided around the gap, and a collecting frame is provided on the inner wall of the discharge port below the guide port.

[0010] Preferably, the inner wall of the collection frame is provided with a through suction pipe, and the other end of the suction pipe is connected to the input end of the air pump.

[0011] Preferably, the heating mechanism includes a mounting ring and an arc-shaped heating plate. The mounting ring is fixedly mounted on the outer wall of the guide rod, and the arc-shaped heating plate is provided on the side wall of the mounting ring.

[0012] Preferably, the conveying and drying mechanism includes a mounting plate located below the mounting ring on the outer wall of the guide rod, an arc-shaped bracket fixedly mounted on the side wall of the mounting plate, a rotating shaft symmetrically rotatable on the arc-shaped bracket, a second gear sleeved on the outer wall of each rotating shaft, a first gear sleeved on the upper end of the slag removal cylinder, the first gear meshing with the second gear, and a fan cooperating with the arc-shaped heating plate on the upper end of the rotating shaft.

[0013] Preferably, the lower end of the slag removal cylinder is provided with a discharge port, which is matched with the packaging box above the transport device.

[0014] The advantages of this invention compared to the prior art are: 1. By setting up a shaking mechanism, the tea leaves pass through the feed trough and the spiral screen in sequence. Since the movement trajectory of the spiral screen is in the up and down direction, the tea leaves are not only moved in the horizontal direction during the sieving process, but also tumbled and shaken in the vertical direction. This movement mode greatly increases the contact frequency and force between the tea leaves and the screen. For clay or impurities that are tightly attached to the tea leaves, this enhanced shaking and tumbling effect helps to break the adhesion between them and the tea leaves, making it easier for the impurities to fall off the tea leaves.

[0015] 2. By setting up a slag removal mechanism, the tea leaves will be subjected to centrifugal force as they pass through the slag removal cylinder, and impurities will fly outward and enter the slag collection cylinder, which facilitates the treatment of waste residue.

[0016] 3. This invention, by setting up a collection mechanism, can collect and centrally process the waste residue collected by centrifugation, as well as the fine fragments shaken off by the spiral screen and the tea leaves that are too small. Attached Figure Description

[0026] Reference Figures 1-5The shaking mechanism 200 includes a fixed plate 210 fixedly installed on the inner wall of the debris removal box 106. A drive motor 201 is mounted on the fixed plate 210. The output end of the drive motor 201 is connected to a connecting shaft 207. The other end of the connecting shaft 207 is connected to a lead screw 202. The other end of the lead screw 202 is rotatably engaged with the inner wall of the shaking box 101.

The outer wall of the spiral screen cylinder 208 is provided with several small holes, which can screen out small fragments and oversized tea leaves and collect them centrally through the collection mechanism 400.

[0028] Reference Figures 1-4 The slag removal mechanism 300 includes a slag removal cylinder 303.

The slag removal cylinder 303 is rotatably disposed inside the slag collection cylinder 304. The slag collection cylinder 304 is fixedly mounted on a support frame 305. The support frame 305 is fixedly disposed on the inner wall of the discharge port 105. The surface of the slag removal cylinder 303 in contact with the slag collection cylinder 304 is provided with a plurality of filter holes. Both the lead screw 202 and the upper outer wall of the slag removal cylinder 303 are provided with pulleys 301. A synchronous belt 302 is sleeved between the pulleys 301.

[0029] The lead screw 202 drives the pulley 301 to rotate, the pulley 301 drives the synchronous belt 302 to rotate, and the synchronous belt 302 drives the slag removal cylinder 303 to rotate on the slag collection cylinder 304. The filter holes on the outer wall of the slag removal cylinder 303 can screen large particles of debris into the slag collection cylinder 304 through centrifugal action, and collect them through the collection mechanism 400.

[0031] The collection frame 402 is used to collect the waste residue collected by centrifugation, as well as the small fragments and oversized tea leaves shaken off by the spiral screen cylinder 208, and to process them centrally. The guide port 401 is used to guide the sieved particles.

[0032] Reference Figures 1-4 The inner wall of the collection frame 402 is provided with a through suction pipe 104, and the other end of the suction pipe 104 is connected to the input end of the air pump.

[0033] Activating the air pump in this way can suck out the impurities in the collection box 402 and process them centrally. This is existing technology and will not be elaborated here.

The first gear 501 meshes with the second gear 502. A fan 504 that cooperates with the arc-shaped heating plate 602 is provided on the upper end of the rotating shaft 503.

[0037] The rotation of the slag removal cylinder 303 drives the first gear 501 to rotate, which in turn drives the second gear 502 to rotate on the arc-shaped support 506. The second gear 502 then drives the fan 504 to rotate, thereby transferring the heat generated by the arc-shaped heating plate 602 to the tea leaves inside the spiral screen cylinder 208 for drying. At this time, the tea leaves are in a tumbling state, which ensures uniform drying and improves the quality of the tea.

[0038] Reference Figures 1-4 The slag removal cylinder 303 is provided with a discharge port 105 at its lower end, and the discharge port 105 cooperates with the packaging box above the transport device 102.

The transport device 102 transports the packaging box filled with tea to the designated location and seals it to complete the packaging work.

[0040] Working principle: S1. Tea leaves pass through the feed trough 103 and the spiral screen cylinder 208. The drive motor 201 is started to drive the connecting shaft 207 and the lead screw 202 to rotate. The lead screw 202 cooperates with the sliding seat 204 to make the sliding seat 204 slide up and down. The sliding seat 204 can drive the spiral screen cylinder 208 to move up and down. The roller 206 is used to reduce the friction between the sliding seat 204 and the inner wall of the shaking box 101. The outer wall of the spiral screen cylinder 208 is provided with several small holes, which can screen out small fragments and oversized tea leaves and collect them through the collection mechanism 400 for centralized processing. S2. The lead screw 202 drives the pulley 301 to rotate, the pulley 301 drives the synchronous belt 302 to rotate, and the synchronous belt 302 drives the slag removal cylinder 303 to rotate on the slag collection cylinder 304. The filter holes on the outer wall of the slag removal cylinder 303 can screen large particles of debris into the slag collection cylinder 304 through centrifugal action, and collect them through the collection mechanism 400. S3. The collection frame 402 is used to collect the waste residue collected by centrifugation, as well as the small fragments and tea leaves that are shaken off by the spiral screen cylinder 208, and to process them centrally. The guide port 401 is used to guide the sieved particles. Starting the air pump can suck out the impurities in the collection frame 402 and process them centrally. S4. The rotation of the slag removal cylinder 303 drives the first gear 501 to rotate. The first gear 501 drives the second gear 502 to rotate on the arc-shaped support 506. The second gear 502 drives the fan 504 to rotate, thereby transferring the heat generated by the arc-shaped heating plate 602 to the tea leaves in the spiral screen cylinder 208 and drying the tea leaves. At this time, the tea leaves are in a tumbling state, which can dry them evenly, thereby improving the quality of the tea leaves. S5. The discharge port 105 is used to quantitatively discharge the material into the packaging box on the transport device 102. The discharge port 105 is equipped with a valve, which is existing technology and will not be described in detail here. The transport device 102 transports the packaging box so that it can be collected again. The transport device 102 transports the packaging box filled with tea to the designated location and seals it to complete the packaging work.
