Description

Technical Field

[0001] The invention belongs to the technical field of tea processing, in particular to a tea processing and conveying device. Background Art

[0002] Tea has a long history in my country. As one of the three major non-alcoholic beverages, tea is suitable for all ages. With the increasing demand for tea, traditional tea production technology can no longer meet the demand. In order to improve the processing efficiency of tea, people have invented various food industrial processing and intelligent manufacturing equipment to assist in tea making, such as spreading machines, withering machines, rolling machines and packaging machines. Conveying devices are required between each device for transportation and delivery to improve the efficiency of tea making.

[0003] A Chinese patent with publication number CN104340601A discloses a tea conveyor, including a first horizontal section frame, a second horizontal section frame, an inclined section frame, a rubber conveyor belt, an active roller and a driving motor. The top of the inclined section frame is fixedly connected to the first horizontal section frame, and the bottom is fixedly connected to the second horizontal section frame. The active roller is installed on the first horizontal section frame, and the driven roller is installed on the second horizontal section frame. A first limiting roller group is provided at the connection between the first horizontal section frame and the inclined section frame, and a second limiting roller group is provided at the connection between the second horizontal section frame and the inclined section frame. The rubber conveyor belt is wound around the active roller, the first limiting roller group, the second limiting roller group and the driven roller. The driving motor is installed on the top of the first horizontal section frame, and the driving motor is connected to the active roller through a transmission belt; a tea baffle is installed on the rubber conveyor belt; by adopting an integrated structure, the problem of tea scattering is effectively solved, and the equipment has the advantages of simple structure and low manufacturing and maintenance costs.

[0033] Tea has a long history in my country. As one of the three major non-alcoholic beverages, tea is suitable for people of all ages. With the increase in people's demand for tea, traditional tea production technology can no longer meet the demand. In order to improve the processing efficiency of tea, people have invented various food industrial processing and intelligent manufacturing equipment to assist in tea making. The problem of tea scattering can be solved by setting a tea baffle 11, but the tea cannot be flattened on the transmission belt 175. During the drying process, setting the same drying conditions will not have a good drying effect on thicker tea leaves, which contain more water. Thinner tea leaves may be over-dried, resulting in brittle tea leaves. Under external force conditions, they are easily broken, resulting in poor tea shape, affecting the sales quality of tea leaves. When the flattening mechanism provided by the present invention is used, the sieved tea leaves are moved by the turning rake teeth 17 during transportation. First, the height of the turning rake teeth 17 is adjusted according to the thickness of the tea leaves that need to be spread out, and the second electric push rod 171 is turned on, and the moving block 172 is driven to move by the output end of the second electric push rod 171, and the turning rake teeth 17 are driven to move by the moving block 172, and the turning rake teeth 17 are adjusted to a suitable height, and then the position of the driving mechanism is adjusted so that the driving mechanism can rotate as the first motor 13 is turned on; the turning rake teeth 17 are driven to rotate by the driving mechanism, and the turning rake teeth 17 will push the excess tea leaves down during the rotation, thereby pushing the tea leaves on the conveyor belt 12 to the set thickness, so as to achieve the flattening of the tea leaves to a suitable height; and then, driven by the conveyor belt 12, the tea leaves are transported upward to the drying box 16. During the drying process, the tea leaves need to be turned and stirred by the toggling mechanism to ensure uniform heating and rapid drying.

[0034] like Figure 1 and Figure 7 As shown, the shaking mechanism includes two connecting rods 151 that are rotatably connected to the side walls of the partition plate 15 through a pin shaft; a plurality of slide grooves 155 are provided on the surface of the conveyor belt 12, and a slide rod 153 is fixed in each of the slide grooves 155; a slider 152 is slidably connected to each of the slide rods 153; the end of the connecting rod 151 away from the partition plate 15 is rotatably connected to the slider 152 through a pin shaft, and a return spring 154 is sleeved on the outer side of the connecting rod 151, and the two ends of the return spring 154 are respectively fixed to the slider 152 and the inner wall of the slide groove 155.

[0035] When the shaking mechanism provided by the present invention is in use, the shaking plate 162 and the turning rake teeth 17 will collide with the partition plate 15 during the shaking or flattening process, which may cause damage to the shaking plate 162 and the turning rake teeth 17. By setting the return spring 154, when passing through the partition plate 15, the partition plate 15 is squeezed and tilted, and the partition plate 15 drives one end of the connecting rod 151 to rotate, and the slider 152 is driven to slide by one end of the connecting rod 151, and the return spring 154 is compressed; when passing through the partition plate 15, under the action of the return spring 154, the slider 152 slides quickly on the slide rod 153, and the connecting rod 151 is driven to rotate by the slider 152, and the partition plate 15 is driven to rotate by the connecting rod 151 until the partition plate 15 is perpendicular to the moving surface of the conveyor belt 12; in addition, by setting the shaking mechanism, during the unloading process, the partition plate 15 is shaken, which makes it easy to shake off the tea leaves on the partition plate 15 and prevent the tea leaves from sticking to the partition plate 15.

[0036] like Figures 1 to 2 As shown, a drying box 16 is fixed to the top of the two baffles 11 , two drying fans 161 are installed in the drying box 16 , and a plurality of heating wires are installed at the bottom of the drying box 16 ; the toggle mechanism is provided below the drying fan 161 .

[0037] When the drying fan 161 provided by the present invention is in use, by turning on the drying fan 161 and the heating wire, the heating wire generates heat, and the drying fan 161 blows the heat toward the tea leaves, thereby accelerating the drying of the tea leaves.

[0038] like Figure 2 and Figure 6 As shown, the toggle mechanism includes a toggle plate 162 rotatably connected to the bottom end of the drying box 16 via a connecting shaft, one end of the connecting shaft extends to the outside of the drying box 16 and is fixedly connected to a gear 163; a rack 164 is provided on one side of the gear 163, and the two racks 164 are connected by a connecting plate 165; a first electric push rod 168 is fixed to the outer wall of the drying box 16, and the output end of the first electric push rod 168 is fixedly connected to one end of an adjacent rack 164.

[0039] When the toggle mechanism provided by the present invention is in use, during the drying process, the tea leaves need to be toggled and turned over, so that the tea leaves are heated evenly and the drying efficiency is improved; by turning on the first electric push rod 168, the output end of the first electric push rod 168 drives the rack 164 to move, and the rack 164 drives the other rack 164 to move through the connecting plate 165, and the synchronous movement of the two racks 164 drives the gear 163 to rotate, and the connecting shaft is driven to rotate by the gear 163, and the toggle plate 162 is driven to rotate back and forth by the connecting shaft, and the tea leaves are toggled and turned over by the toggle plate 162; when the toggle plate 162 contacts the partition plate 15, the first electric push rod 168 is controlled to retract rapidly through the system program, so that the rack 164 moves rapidly toward the first electric push rod 168, and the gear 163 rotates rapidly clockwise to a horizontal position until the partition plate 15 moves through the toggle plate 162, so as to prevent the toggle plate 162 and the partition plate 15 from being stuck.

[0040] like Figure 6 As shown, the connecting plates 165 are each provided with a sliding opening 166 ; two limiting blocks 167 are fixedly connected to the outer wall of the drying box 16 , and the limiting blocks 167 are slidably connected in the sliding opening 166 .

[0041] When the limit block 167 provided by the present invention is in use, the rack 164 drives the connecting plate 165 to move during the movement. During the movement of the connecting plate 165, the limit block 167 slides in the sliding opening 166, and the rack 164 is limited to move in the horizontal direction by the limit block 167.

[0042] like Figure 3 and Figure 5 As shown, the driving mechanism includes a first rotating wheel 174, a second rotating wheel 176, a tensioning wheel 177 and a belt 175; the first rotating wheel 174 is fixedly connected to one end of the rotating shaft of the material turning rake 17; the second rotating wheel 176 is fixedly connected to one end of the roller shaft at the bottom end of the conveyor belt 12; the tensioning wheel 177 is provided with a pressure sensor; the tensioning wheel 177 is arranged on the outside of the baffle 11 through an adjusting mechanism; the belt 175 is sleeved on the outside of the first rotating wheel 174, the second rotating wheel 176 and the tensioning wheel 177.

[0043] The driving mechanism provided by the present invention is used to drive the turning rake teeth 17 to rotate when in use. By turning on the first motor 13, the connected roller shaft is driven to rotate by the first motor 13, and the roller shaft cooperates with the conveyor belt 12, so that the roller shaft below also rotates. The second rotating wheel 176 is driven to rotate by the second rotating wheel 176, and the belt 175 is driven to rotate by the belt 175. The first rotating wheel 174 and the tensioning wheel 177 are driven to rotate by the belt 175, and the rotating shaft is driven to rotate by the first rotating wheel 174, and the turning rake teeth 17 are driven to rotate by the rotating shaft. The tea leaves are turned and flattened by the turning rake teeth 17; the sizes of the first rotating wheel 174 and the second rotating wheel 176 can be set to be the same or different. The sizes of the first rotating wheel 174 and the second rotating wheel 176 are adjusted according to the speed requirements.

[0044] like Figure 5 As shown, the adjustment mechanism includes two fixed plates 18 fixed to the outer wall of the baffle 11, and a reciprocating screw 183 is rotatably connected between the two fixed plates 18 through a bearing, and a movable plate 181 is threadedly connected to the reciprocating screw 183, and the top of the movable plate 181 is fixed with a mounting seat 178, and the tensioning wheel 177 is rotatably connected in the mounting seat 178; two guide rods 184 are fixed between the two fixed plates 18, and the movable plate 181 is slidably connected to the two guide rods 184; a second motor 182 is fixed to one of the fixed plates 18, and the output shaft of the second motor 182 is fixed to one end of the reciprocating screw 183.

[0045] When the adjustment mechanism provided by the present invention is in use, the turning rake teeth 17 are adjusted to different heights, and the tightness of the belt 175 is different. When the moving block 172 is moving, the tension of the belt 175 changes, and the pressure between the belt 175 and the tensioning pulley 177 changes. The signal is transmitted to the system through the pressure sensor, and the second motor 182 is controlled by the system. The reciprocating screw 183 is driven to rotate by the output shaft of the second motor 182, and the moving plate 181 is driven to move by the reciprocating screw 183, and the mounting seat 178 is driven to move by the moving plate 181, and the tensioning pulley 177 is driven to move by the mounting seat 178 until it moves to a suitable position, ensuring that the belt 175 can drive the rotation of the first rotating wheel 174, the second rotating wheel 176 and the tensioning pulley 177.

[0046] like Figure 2 As shown, an annular bottom plate 14 is fixedly connected between the inner walls of the bottom ends of the two baffles 11 ; the inner side wall of the annular bottom plate 14 contacts the end surface of the partition plate 15 away from the conveyor belt 12 .

[0047] When the annular bottom plate 14 provided by the present invention is in use, after the turning rake teeth 17 push out the excess tea leaves, the tea leaves may accumulate at the end of the conveyor belt 12, and the tea leaves may overflow from the end of the conveyor belt 12. The annular bottom plate 14 is provided to facilitate the collection of the tea leaves, and then during the rotation of the partition plate 15, the tea leaves are transported again to the top of the conveyor belt 12, thereby reducing the waste of raw materials.

[0048] like Figure 1 and Figure 8 As shown, a support frame 2 is provided on one side of the conveyor belt 12; a dust hopper 21 is fixedly connected to the top of the support frame 2; two side plates 27 are symmetrically fixed to the side walls of the dust hopper 21; vertical rods 26 are fixed to the tops of the side plates 27; a first screen basket 22 is provided above the dust hopper 21; a second screen basket 23 is provided above the first screen basket 22; the outer wall of the first screen basket 22 is slidably connected to the vertical rod 26 by four first slides; the outer wall of the second screen basket 23 is slidably connected to the vertical rod 26 by four second slides; vibrators are installed at the bottoms of the first screen basket 22 and the second screen basket 23; the outer sides of the vertical rods 26 are respectively provided with a first spring 28 and a second spring 29; the two ends of the first spring 28 are respectively fixed to the side plate 27 and the first slide; the two ends of the second spring 29 are respectively fixed to the second slide and the first slide; the first screen basket 22 is provided with a first filter hole, and the second screen basket 23 is provided with a second filter hole, and the first filter hole is smaller than the aperture of the second filter hole.

[0049] When the first sieve basket 22 and the second sieve basket 23 provided by the present invention are in use, the vibrator is turned on to facilitate the vibration of the first sieve basket 22 and the second sieve basket 23, and the vibration of the first sieve basket 22 and the second sieve basket 23 is intensified under the action of the first spring 28 and the second spring 29. Large particles of tea leaves are filtered through the second sieve basket 23, and small particles of tea leaves are filtered through the first sieve basket 22. Finally, impurities such as dust and sand are filtered into the ash hopper 21 through the first sieve basket 22, thereby realizing the grading and screening of tea leaves and the cleaning of impurities.

[0050] like Figure 8 As shown, the first screen basket 22 is fixedly connected to a first discharge plate 24 at one end close to the conveyor belt 12; the first discharge plate 24 is directly above the conveyor belt 12; the second screen basket 23 is fixedly connected to a second discharge plate 25 at one end close to the conveyor belt 12; the discharge end of the second discharge plate 25 extends to one side of the conveyor belt 12.

[0051] When the first discharge plate 24 and the second discharge plate 25 provided by the present invention are in use, the small-particle tea leaves filtered by the first screen basket 22 slide through the first discharge plate 24 and are transported onto the conveyor belt 12 below; the large-particle tea leaves filtered by the second screen basket 23 slide through the second discharge plate 25 and are transported onto the conveyor belt 12 on one side, thereby realizing the transportation and processing of tea leaves of different particle sizes.

[0052] Working principle:

[0053] When screening materials, the vibrator is turned on to facilitate the vibration of the first screen basket 22 and the second screen basket 23, and the vibration of the first screen basket 22 and the second screen basket 23 is intensified under the action of the first spring 28 and the second spring 29. Large particles of tea leaves are filtered through the second screen basket 23, and small particles of tea leaves are filtered through the first screen basket 22. Finally, impurities such as dust and sand are filtered into the ash hopper 21 through the first screen basket 22, thereby realizing the grading and screening of tea leaves and the cleaning of impurities; the small particles of tea leaves filtered through the first screen basket 22 slide through the first discharging plate 24 and are transported onto the conveyor belt 12 below; the large particles of tea leaves filtered through the second screen basket 23 slide through the second discharging plate 25 and are transported onto the conveyor belt 12 on one side, thereby realizing the transportation and processing of tea leaves of different particle sizes.

[0054] When the tea leaves are spread out and the sieved tea leaves are transported, the turning rake teeth 17 are moved. First, the height of the turning rake teeth 17 is adjusted according to the thickness of the tea leaves to be spread out. By turning on the second electric push rod 171, the moving block 172 is driven to move by the output end of the second electric push rod 171, and the turning rake teeth 17 are driven to move by the moving block 172, and the turning rake teeth 17 are adjusted to a suitable height. Then, by adjusting the position of the driving mechanism, the driving mechanism can rotate as the first motor 13 is turned on; by turning on the first motor 13, the connected roller is driven to rotate by the first motor 13, and the roller below is also rotated through the cooperation of the roller and the conveyor belt 12, and the second roller 176 is driven to rotate by the roller, and the belt 175 is driven to rotate by the second roller 176, and the first roller 174 and the tensioning pulley 177 are driven to rotate by the belt 175, and the rotating shaft is driven to rotate by the first roller 174, and the turning rake teeth 17 are driven to rotate by the rotating shaft. During the rotation process, the turning rake teeth 17 will remove excess tea leaves. The tea leaves are then moved upwards to the drying box 16 driven by the conveyor belt 12. During the drying process, the tea leaves need to be moved and turned over by the toggling mechanism so that they are evenly heated and dried quickly. The turning rake teeth 17 are adjusted to different heights, and the tightness of the belt 175 is different. When the moving block 172 is moving, the tension of the belt 175 changes, and the pressure between the belt 175 and the tensioning wheel 177 changes. The signal is transmitted to the system through the pressure sensor, and the second motor 182 is controlled by the system. The reciprocating screw 183 is driven to rotate by the output shaft of the second motor 182, and the moving plate 181 is driven to move by the reciprocating screw 183. The mounting seat 178 is driven to move by the moving plate 181, and the tensioning wheel 177 is driven to move by the mounting seat 178 until it moves to the appropriate position to ensure that the belt 175 can drive the rotation of the first rotating wheel 174, the second rotating wheel 176 and the tensioning wheel 177.

[0055] When toggling, during the drying process, the tea leaves need to be toggled and turned over so that the tea leaves are heated evenly and the drying efficiency is improved; by turning on the first electric push rod 168, the output end of the first electric push rod 168 drives the rack 164 to move, and the rack 164 drives the other rack 164 to move through the connecting plate 165, and the synchronous movement of the two racks 164 drives the gear 163 to rotate, and the connecting shaft is driven to rotate by the gear 163, and the toggle plate 162 is driven to rotate back and forth by the connecting shaft, and the tea leaves are toggled and turned over by the toggle plate 162; when the toggle plate 162 contacts the partition plate 15, the first electric push rod 168 is controlled by the system program to retract rapidly, so that the rack 164 moves rapidly toward the first electric push rod 168, and the gear 163 rotates rapidly clockwise to a horizontal position until the partition plate 15 moves through the toggle plate 162 to prevent the toggle plate 162 and the partition plate 15 from getting stuck.

[0056] During the shifting or flattening process, the shifting plate 162 and the turning rake teeth 17 will collide with the partition plate 15, which may cause damage to the shifting plate 162 and the turning rake teeth 17. By setting the return spring 154, when passing through the partition plate 15, the partition plate 15 is squeezed and tilted, and the partition plate 15 drives one end of the connecting rod 151 to rotate, and drives the slider 152 to slide through one end of the connecting rod 151, and the return spring 154 is compressed; when passing through the partition plate 15, under the action of the return spring 154, the slider 152 slides quickly on the slide bar 153, and drives the connecting rod 151 to rotate through the slider 152, and drives the partition plate 15 to rotate through the connecting rod 151 until the partition plate 15 is perpendicular to the moving surface of the conveyor belt 12; in addition, by setting the shaking mechanism, during the unloading process, the partition plate 15 is shaken to facilitate shaking off the tea leaves on the partition plate 15, and prevent the tea leaves from sticking to the partition plate 15.
