Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, and in particular to a tea processing cooling and conveying mechanism. Background Technology

[0002] In the traditional tea production and processing industry, the general production process for tea varieties that require rolling is as follows: withering → fixation → rolling → drying → packaging. The roasted tea leaves (fixation process) are transported to the rolling process by a transport device. At this time, the tea temperature is relatively high, and a mesh belt is needed to transfer the tea leaves.

[0003] For example, the utility model disclosed in announcement number CN206534040U is a tea mesh belt conveyor cooling machine. The tea leaves are vibrated and fall onto the second mesh conveyor belt. During the falling process, they come into contact with the cold air inside the shell, completing the heat exchange and heat dissipation process, and then fall onto the second mesh conveyor belt and are sent out of the outlet. This reduces the temperature of the tea leaves. In addition, the heat dissipation effect of the mesh of the first and second mesh conveyor belts can maximize the reduction of the temperature of the tea leaves after fixation, which is beneficial to the subsequent processes such as rolling.

[0004] However, when the conveying equipment in the above application is used to transport tea, the tea leaves tend to pile up on the conveyor belt, making it difficult to spread the tea leaves out and affecting the cooling effect. Manually spreading the tea leaves out is time-consuming and labor-intensive, affecting processing efficiency. Therefore, a tea processing cooling conveying mechanism is proposed to solve the above problems. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] like Figure 1-3 As shown, the present invention proposes a tea processing cooling and conveying mechanism, which includes a support frame 1 and a conveying component 2 disposed on the support frame 1. A support leg 3 is fixedly connected to the lower surface of the support frame 1, and a cooling component 5 is disposed on the support frame 1.

[0028] In this utility model, a control panel 4 is provided on the front of the support frame 1. The control panel 4 controls the opening and closing of electrical components, while the cooling component 5 located on the support frame 1 vibrates and flattens the conveyed tea leaves while blowing air to cool them.

[0029] In an optional embodiment, the cooling component 5 includes a mounting bracket 51 fixedly connected to the support frame 1. Air guide chambers 52 are fixedly connected to both the front and rear sides of the mounting bracket 51. A set of blowers 53 is fixedly mounted on each of the two air guide chambers 52. A set of exhaust fans 54 is fixedly mounted on the upper surface of the mounting bracket 51. A set of support plates 56 is fixedly connected to the upper surface of the mounting bracket 51. A servo motor 55 is fixedly connected to the front support plate 56. A threaded rod 57 is fixedly connected to the output shaft of the servo motor 55. The outer side of 57 is threaded with a drive block 58 that passes through the mounting bracket 51. The lower end of the drive block 58 is fixedly connected to a long strip 510. The lower end of the long strip 510 is fixedly connected to a number of scraper rods 59. The inner side of the support frame 1 is fixedly connected to a base plate 512. A telescopic rod 514 is fixedly connected to the base plate 512. A vibrating plate 515 is fixedly connected to the upper end of the telescopic rod 514. A rotating shaft 516 is rotatably connected to the support frame 1. A set of cams 513 is fixedly connected to the rotating shaft 516.

[0030] In this embodiment, when the tea leaves are conveyed by the conveyor belt 23, the started drive motor 21 can also drive the rotating shaft 516 to rotate synchronously through the transmission component 22, so that the cam 513 on the rotating shaft 516 repeatedly pushes up the vibrating plate 515 to shake and flatten the tea leaves that have passed through the vibrating plate 515. Meanwhile, the scraper rod 59 driven by the threaded rod 57 moves back and forth to scrape the flattened tea leaves, leaving gaps between the tea leaves to improve the heat dissipation of the tea leaves, thereby improving the cooling effect of the tea leaves and improving the tea processing efficiency.

[0031] It should be noted that the end of the threaded rod 57 away from the servo motor 55 passes through the front support plate 56 and is rotatably connected to the rear support plate 56. The middle part of the drive block 58 is provided with a threaded hole located on the outside of the threaded rod 57. The threaded hole and the thread on the outside of the threaded rod 57 cooperate with each other, so that the rotating threaded rod 57 can drive the drive block 58 and the long strip block 510 to move back and forth along the vertical horizontal plane.

[0032] The inner wall of the mounting bracket 51 has a ventilation hole 511 that communicates with the air guide chamber 52, so that the activated blower 53 can blow natural air to the inside of the mounting bracket 51 through the air guide chamber 52 and the ventilation hole 511. The inner top wall of the mounting bracket 51 has a rectangular groove for the long strip block 510 to move, so that the long strip block 510 has room to move when it moves with the drive block 58.

[0033] In addition, the inner top wall of the mounting bracket 51 is provided with an air outlet that is connected to the rectangular groove and the air inlet of the exhaust fan 54, so that the activated exhaust fan 54 can extract the hot air blown out of the mounting bracket 51 through the air outlet. The inner top wall of the mounting bracket 51 is provided with a rectangular hole that allows the drive block 58 to move and is connected to the rectangular groove, so that the drive block 58 passing through the mounting bracket 51 has space to move.

[0034] Secondly, the scraper rod 59 consists of a sleeve rod 591, a connecting spring 592, and a scraper rod 593. The sleeve rod 591 is fixedly connected to the long strip block 510, and the scraper rod 593 is slidably connected to the inner side of the sleeve rod 591. The connecting spring 592 is fixedly connected between the upper end of the scraper rod 593 and the inner side of the sleeve rod 591, so that when the lower end of the scraper rod 59 is squeezed by the vibrating plate 515, it can extend and retract without affecting the vibration of the vibrating plate 515. At the same time, after moving back and forth with the long strip block 510, it can scrape the conveyed tea leaves, leaving gaps between the tea leaves.

[0035] Then, the telescopic rod 514 is composed of a sleeve, a vertical rod and a support spring. The sleeve is fixedly connected to the base plate 512, the vertical rod is slidably connected to the inside of the sleeve, the support spring is fixedly connected between the lower end of the vertical rod and the inside of the sleeve, and the upper end of the vertical rod is fixedly connected to the vibrating plate 515, so that the telescopic rod 514 can elastically support the vibrating plate 515.

[0036] In an optional embodiment, the conveyor 2 includes a drive motor 21 fixedly installed on the front side of the support frame 1. A set of belt rollers 24 are rotatably connected to the inner side of the support frame 1, and one end of the left belt roller 24 is fixedly connected to the output shaft of the drive motor 21. A conveyor belt 23 is sleeved on the belt roller 24, and a transmission component 22 is provided at one end of the front belt roller 24 and the rotating shaft 516.

[0037] In this embodiment, after the left belt roller 24 is driven to rotate by the drive motor 21, the conveyor belt 23 supported by the belt roller 24 can be driven to rotate, and the tea leaves that need to be cooled can be conveyed. The rotating left belt roller 24 can also drive the rotating shaft 516 to rotate synchronously through the transmission component 22.

[0038] It should be noted that the transmission assembly 22 includes two pulleys that are fixedly connected to the front belt roller 24 and the end of the rotating shaft 516 respectively. A transmission belt is sleeved on the outside of the pulleys so that the rotating left belt roller 24 can drive the rotating shaft 516 to rotate synchronously through the pulleys and the transmission belt.

[0039] Furthermore, an arc-shaped groove is provided on the upper surface of the vibrating plate 515, and a guide roller is rotatably connected in the arc-shaped groove through a rotating shaft to reduce the friction force after the vibrating plate 515 comes into contact with the conveyor belt 23.

[0040] The control panel 4 on the support frame 1 is electrically connected to the drive motor 21, the blower 53, the exhaust fan 54, and the servo motor 55. The control panel 4 controls the opening and closing of the drive motor 21, the blower 53, the exhaust fan 54, and the servo motor 55. The control panel 4, the drive motor 21, the blower 53, the exhaust fan 54, and the servo motor 55 are all powered by conventional mains power. Since the above control and power supply methods are all conventional technical means, they will not be described in detail in this article.

[0041] The working principle in the above embodiments is as follows:

[0042] After the drive motor 21 drives the conveyor belt 23 to rotate, it can transport the tea leaves that need to be cooled on the conveyor belt 23. The left belt roller 24, which starts to rotate, can also drive the rotating shaft 516 to rotate synchronously through the transmission component 22. This causes the cam 513 on the rotating shaft 516 to repeatedly push up the vibrating plate 515, shaking and flattening the tea leaves that have passed the vibrating plate 515 on the conveyor belt 23. At the same time, the servo motor 55, which starts to operate, drives the threaded rod 57 to drive the drive block 58 and the scraper rod 59 on the long strip block 510 to move back and forth. This scrapes the flattened tea leaves, leaving gaps between the tea leaves and improving the heat dissipation of the tea leaves, thereby improving the cooling effect and cooling rate of the tea leaves. While the two sets of blowers 53 on the mounting frame 51 blow air to cool the tea leaves, a set of exhaust fans 54 above the mounting frame 51 can exhaust the hot air blown by the mounting frame 51 and the hot air with condensed water vapor when it encounters cold.

[0043] 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.
