DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] Reference Figure 1-2 An embodiment of the present invention discloses a tea processing and drying device, which is used to solve the problem that tea leaves are piled up in a material frame and it is difficult to achieve a comprehensive drying effect during the current tea drying process. Preferably, the drying device described in this embodiment includes a frame 1 and a drying box 2 fixed on the frame 1, the drying box 2 is sleeved on the top of the frame 1, and a hot air component 3 is arranged above the drying box 2. Specifically, the hot air component 3 described in this embodiment includes a heating box fixed and connected to the top of the drying box 2, a fan is fixedly installed on the top of the heating box, and a heating wire is arranged inside, and the heat of the heating wire is blown into the interior of the drying box 2 by the fan to achieve drying of the tea leaves. This means is a prior art and is not described in detail in this section.

[0032] Among them, an outer frame 4 is also fixedly installed on the side of the frame 1, a sliding assembly 5 is arranged between the outer frame 4 and the drying box 2, a material frame assembly 6 for storing tea leaves is installed on the sliding assembly 5, and a channel 21 for the material frame assembly 6 to enter and exit is arranged on the end surface of the drying box 2, and the material frame assembly 6 includes a material frame 61 and a peristaltic mechanism arranged in the material frame 61.

[0033] Reference Figure 3 In some embodiments, the sliding assembly 5 in the present invention includes two guide rods 51 fixedly installed between the frame 1 and the upper end of the outer frame 4, and at least one support frame 52 is slidably connected between the two guide rods 51. The material frame assembly 6 is connected to at least one of the support frames 52. Specifically, two support frames 52 are provided in this embodiment, and the two support frames 52 slide with the guide rods 51 through sliders, so that the position of the material frame assembly 6 can be moved so that it can slide from the outer frame 4 along the channel 21 to the inside of the drying box 2.

[0034] Reference Figure 5 , 6Furthermore, the peristaltic mechanism in this embodiment includes a rotating shaft 62 rotatably connected to the inner side of the material frame 61, and a swing arm 63 is fixedly installed at the end of the rotating shaft 62, wherein the inner side of the material frame 61 is also slidably connected to a push frame 64, and the end of the swing arm 63 is fixedly installed with a driving shaft 65 located inside the push frame 64, and an elastic membrane 68 covering the top of the push frame 64 is fixed to the inner side of the material frame 61, and the elastic membrane 68 can be provided with a high temperature resistant silicone membrane, and with the help of the elasticity of the silicone membrane, when the rotating shaft 62 rotates, the rotating shaft 6 The push frame 64 is driven to reciprocate inside the material frame 61 by means of the swing arm and the driving shaft 65, so that the tea leaves placed on the elastic membrane 68 can be lifted up in a reciprocating manner, achieving a peristaltic turning effect on the tea leaves, so that the tea leaves at the bottom can be fully exposed to the hot air, thereby achieving a comprehensive drying effect on the tea leaves. At the same time, the peristaltic turning design will not damage the tea leaves compared to the stirring method of the stirring rod in the prior art, so it can achieve the maximum protection of the integrity of the tea leaves during the drying process. In addition, the driving method of the rotating shaft 62 will be described in detail later and will not be described here.

[0035] Reference Figure 6 On the basis of the above embodiment, in this embodiment, at least one plug rod 66 is fixedly installed at the bottom of the material frame 61, and the plug rod 66 is plugged into the support frame 52, wherein a positioning glass bead 67 is embedded on the outer side of the plug rod 66. Preferably, the plug rods 66 described in this embodiment can be distributed in a matrix with four, and positioning glass beads 67 are embedded on both sides of each of the plug rods 66. Of course, a plug hole should be opened on the end surface of the support frame 52. When installing the material frame 61, it is only necessary to plug the plug rod 66 into the plug hole until the telescopic end of the positioning glass bead 67 pops out and snaps into the bottom of the support frame 52 to complete the installation of the material frame 61.

[0036] Reference Figure 3 , 7 8. In a preferred embodiment, considering that the positioning glass bead 67 in the above scheme is not convenient for subsequent disassembly after the clamping action is completed, two abutment blocks 41 are fixedly installed on the top of the outer frame 4 in the present invention, and the insertion rod 66 slides between the two abutment blocks 41. The abutment blocks 41 abut the positioning glass bead 67 to retract. It should be noted that the distance between the top of the abutment block 41 and the bottom of the support frame 52 should not be too large to avoid the telescopic end of the positioning glass bead 67 being clamped in the gap between the two.

[0037] Reference Figure 6Specifically, the friction blocks 41 described in the present invention are provided with four, and each two form a group. During installation, when the insertion rod 66 is inserted into the support frame 52, the positioning glass bead 67 receives the bottom of the friction block 41 and cannot pop out. Therefore, when the material frame 61 is on the outer frame 4, it can be freely disassembled and installed, so that the tea leaves can be conveniently loaded and subsequently exported after drying. When the material frame 61 moves toward the inside of the drying box 2, the positioning glass bead 67 pops out after being separated from the friction of the friction block 41, so that it can be stopped at the bottom of the support frame 52, completing the limitation of the material frame 61, so as to ensure the stability of the position of the material frame 61 during the subsequent drying process.

[0038] Reference Figure 3 , 7 -9, it should be noted that, in order to realize the position driving of the material frame 61 in the present invention, the present invention also includes a driving mechanism 7, and the driving mechanism 7 is used to drive the material frame 61 along the upper side of the outer frame 4 through the channel 21 into the drying box 2.

[0039] Specifically, the driving mechanism 7 in the present invention includes a screw 71 rotatably connected between the outer frame 4 and the drying box 2, the screw 71 is threadedly connected to the support frame 52, and a driving motor 72 is fixedly installed on the lower side of the outer frame 4. The driving motor 72 is driven by the screw 71 through a belt and a pulley, and an avoidance groove for the belt to pass through is opened on the end surface of the outer frame 4.

[0040] That is, during actual operation, the driving motor 72 drives the screw 71 to rotate. Since the screw 71 is threadedly connected to the support frame 52, the support frame 52 is driven to move in a linear position to coordinate the movement of the material frame 61, so that the material frame 61 can be driven to the inside of the drying box 2 for drying. After drying, the driving motor 72 is reversed to push the material frame 61 back to the outer frame 4 for subsequent unloading processing.

[0041] Reference Figure 4 , 6, 7, 8. In some embodiments, the bottom end of the rotating shaft 62 in the present invention passes through the bottom of the material frame 61 and is fixedly installed with a first gear 621. A motor 22 is provided at the bottom of the drying box 2. A second gear 23 is fixed to the shaft end of the motor 22. The second gear 23 is meshed with the first gear 621. It should be noted that the first gear 621 described in this embodiment is located above the screw 71 to avoid interference in movement. Of course, the second gear 23 is arranged at the upper end of the frame 1 and is located on one side of the screw 71. The first gear 621 is engaged with the second gear 23 at the side to realize that the motor 22 drives the second gear 23 to rotate. By cooperating with the first gear 621, the pushing frame 64 is driven to reciprocate inside the material frame 61, thereby realizing the peristaltic flipping of the tea leaves in the material frame 61 to improve the drying effect.

[0042] Reference Fig. 9 On the basis of the above embodiment, in the present invention, two slide bars 11 are fixedly installed at the bottom of the frame 1, a slide seat 12 is slidably connected between the two slide bars 11, the motor 22 is fixed on the slide seat 12, a spring 13 is fixed between the slide seat 12 and the frame 1, and a straight groove 24 is opened on the inner side of the drying box 2 to avoid the shaft end of the motor 22.

[0043] Specifically, in order to protect the meshing process of the first gear 621 and the second gear 23 and avoid tooth hitting when the first gear 621 and the second gear 23 are meshed, a slidable slide 12 is used to support the motor 22. When the material frame 61 enters, if tooth hitting occurs when the first gear 621 contacts the second gear 23, the slide 12 will resist the spring 13 and contract. Since the first gear 621 receives a reverse thrust, when the first gear 621 continues to move forward, the second gear 23 will push the first gear 621 to rotate and adjust the angle, thereby achieving complete meshing of the first gear 621 and the second gear 23. At this time, the slide 12 drives the motor 22 to move and reset.

[0044] Reference Figure 3 , 4On the basis of the above-mentioned embodiment, in consideration of locking the position of the motor 22 when it is working, in order to avoid the situation of slipping teeth and the like in the subsequent driving due to its movable position, the upper end of the frame 1 described in the present invention is slidably connected with a contact frame 8, and a compression spring 81 is fixedly installed between the contact frame 8 and the upper end of the frame 1. Preferably, in this embodiment, a positioning block is fixedly installed on the top of the frame 1, and the contact frame 8 is inserted and slid with the positioning block through a guide rod, and the compression spring 81 is sleeved on the outer side of the guide rod, wherein a limiting portion 82 for stopping the shaft end of the second gear 23 is fixed on one side of the contact frame 8, and an arc-shaped opening 83 is opened at one end of the contact frame 8 toward the insertion rod 66, and an avoidance opening 84 for avoiding the positioning glass bead 67 is arranged on the end surface of the contact frame 8, and the avoidance opening 84 is connected with the arc-shaped opening 83, and the avoidance opening 84 is designed to avoid the positioning glass bead 67, so as to protect the clamping ability of the positioning glass bead 67.

[0045] Specifically, that is to say, in the present invention, when the material frame 61 enters the interior of the drying box 2, the insertion rod 66 at the bottom of the material frame 61 abuts against the abutment frame 8 to move it to one side, and when the first gear 621 is meshed with the second gear 23, the limiting portion 82 of the abutment frame 8 stops on the outside of the shaft end of the second gear 23. Of course, in order to adapt to the situation that the second gear 23 may move during the initial contact, the stopping action of the limiting portion 82 in the present invention should be after the contact action of the first gear 621 and the second gear 23, so that when the first gear 621 is fully meshed with the second gear 23, the limiting portion 82 stops on the outside of the shaft of the second gear 23 to lock its position and improve the stability of subsequent driving.

[0046] In summary, the design of the outer frame 4 adopted in the present invention can realize the convenient installation and disassembly of the material frame 61, thereby improving the convenience of loading and unloading the tea leaves. Secondly, the interior of the material frame 61 of the present invention realizes the reciprocating lifting and peristalsis of the elastic membrane 68 through the reciprocating movement of the push frame 64. This structural design realizes the peristaltic flipping effect on the tea leaves, which can make the tea leaves at the bottom fully contact with the hot air, thereby achieving a comprehensive drying effect on the tea leaves. At the same time, the peristaltic flipping design will not damage the tea leaves compared to the stirring method of the stirring rod in the prior art. Therefore, it can achieve maximum protection of the integrity of the tea leaves during the drying process.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
