Description

Technical Field

[0001] This application relates to the field of tea production equipment, and more particularly to a tea bag sorting machine. Background Technology

[0002] Tea refers to the dried beverage raw material made from the leaves and buds of the tea plant after processing. It has rich cultural connotations and health benefits.

[0003] Freshly picked tea leaves undergo a series of processes, including fixation, rolling, and drying, to produce refined tea. Loose tea leaves are then packaged into tea bags, which are then arranged and packaged to create finished tea gift boxes that can be sold.

[0004] During the packaging and conveying process of tea bags, a large number of tea bags enter the conveyor mechanism at once and are transported to the subsequent packaging station. Due to the stacking or piling of materials, tea bags are prone to getting stuck. Therefore, during operation, it is often necessary to arrange an operator at the conveyor mechanism to move the stuck tea bags to resolve the problem and facilitate the smooth progress of production. This method incurs additional labor costs and needs to be improved. Utility Model Content

[0005] Based on this, this application provides a tea bag feeding machine that can greatly improve the problem of material jamming when tea bags are conveyed to the packaging station. It has a high degree of automation and saves additional labor costs.

[0006] The tea bag sorting machine provided in this application adopts the following technical solution:

[0007] A tea bag sorting machine, comprising:

[0008] Equipment assembly;

[0009] The main conveyor line includes multiple sets of conveyor rollers rotatably mounted on the equipment assembly. Several anti-stacking mechanisms are provided above the conveyor roller sets. There is a material passage area between the anti-stacking mechanisms and the conveyor roller sets for a single tea bag to pass through.

[0010] The pushing mechanism includes a brush roller fixedly mounted on the equipment assembly and a first motor for driving the brush roller to rotate. The brush roller is located outside one of the conveying roller groups, and a dispensing area for tea bags to pass through is formed between the brush roller and the equipment assembly.

[0011] The receiving box is located below the main conveyor line and is used to receive tea bags falling from the main conveyor line.

[0012] The return conveyor line is located between the receiving box and the main conveyor line, and is used to re-transport tea bags back to the main conveyor line.

[0013] Optionally, the anti-stacking mechanism includes a brush plate and a first adjusting component for fixing the brush plate. The brush plate is fixed to the equipment assembly by the first adjusting component, and the material conveying area is located between the brush plate and the conveyor roller group.

[0014] Optionally, the first adjustment component includes a first connecting rod fixedly connected to the equipment assembly, a first adjusting block rotatably sleeved on the first connecting rod, a second connecting rod rotatably inserted into the first adjusting block, and a second adjusting block rotatably sleeved on the second connecting rod. The first adjusting block and the first connecting rod, the second connecting rod and the first adjusting block, and the second adjusting block and the second connecting rod are all fixed by locking members; the brush plate is fixed to the free end of the second adjusting block.

[0015] Optionally, the conveyor roller assembly includes a roller shaft rotatably mounted on the equipment assembly and a drive assembly for driving the roller shaft to rotate synchronously, with the end of the roller shaft away from the equipment assembly being higher than the end of the roller shaft near the equipment assembly.

[0016] Optionally, the roller shaft located at the front end of the brush roller in the tea bag conveying direction is designated as the first roller shaft, and the roller shaft located at the front end of the brush roller in the tea bag conveying direction is designated as the second roller shaft, wherein the axial length of the first roller shaft is greater than the axial length of the second roller shaft.

[0017] Optionally, the conveying front end of the main conveyor line is equipped with an anti-jamming mechanism; wherein, the anti-jamming mechanism includes a fixedly installed material support plate, the material support plate is provided with multiple strip holes, each strip hole is for a roller shaft to pass through partially.

[0018] Optionally, the rotational speed of the rollers located at the front end of the main conveyor line in each set of conveyor rollers is always less than the rotational speed of the rollers located at the rear end of the main conveyor line.

[0019] Optionally, a material distribution mechanism is provided at the rear end of the conveying main line. The material distribution mechanism includes a roller mounted on the equipment assembly and a second motor for driving the roller to rotate. The roller is located above the conveying main line, and the rotational speed of the roller is always greater than the rotational speed of the conveying roller group directly opposite it.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. When the tea bag sorting machine of this application is in use, a large number of tea bags can be blocked by the pushing mechanism at the front end of the main conveyor line. The brush roller rotates in the opposite direction to the tea bag conveying direction under the drive of the first motor, which can push the accumulated tea bags away from the main conveyor line and make them fall into the receiving box, which can effectively improve the situation of tea bag accumulation. The tea bags that fall into the receiving box can be orderly returned to the main conveyor line under the conveying of the return conveyor line, so that each tea bag can smoothly enter the packaging station.

[0022] 2. After the tea bags pass through the material distribution area between the pushing mechanism and the equipment assembly, their stacking situation is greatly improved. However, there may be some tea bags partially stacked. The stacked tea bags are conveyed forward to the anti-stacking mechanism and can be blocked by the brush plate. Under the friction and resistance of the brush plate, the stacked tea bags are separated from each other. After separation, the individual tea bags can pass through the material handling area smoothly, which greatly improves the jamming situation when conveying tea bags, realizes the automatic material handling operation of tea bags, and saves additional labor costs.

[0023] 3. By adjusting the positions of the first adjusting block, the second connecting rod, and the second adjusting block, the distance between the brush plate and the conveyor roller group can be smoothly adjusted, thereby controlling the distance between the brush roller and the conveyor roller group within the thickness range of a single tea bag. This facilitates the separation of stacked tea bags and the smooth transport of a single tea bag to the packaging station.

[0024] 4. The material support plate is designed to block the gap between adjacent rollers, which can reduce the chance of tea bags getting stuck between adjacent rollers when a large number of tea bags enter the front end of the conveyor line, thus reducing the probability of failure.

[0025] 5. By making the roller speed at the rear end of the conveyor greater than that at the front end, the problem of tea bags piling up at the rear end due to excessively fast material speed at the front end of the conveyor can be improved. This also helps reduce the possibility of tea bags getting stuck, so that the tea bag sorting machine can automatically complete the tea bag sorting operation.

[0026] 6. By setting up a material distribution mechanism, the rollers rotate at high speed under the drive of the second motor. When the tea bags enter the area between the rollers and the conveyor roller group, they can be carried forward quickly by the rollers, thereby performing a final separation of the tea bags, so that the tea bags entering the packaging station are strictly counted as single pieces.

[0033] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail.

[0034] This application discloses a tea bag sorting machine.

[0035] Reference Figure 1 A tea bag sorting machine includes an equipment assembly 1. The equipment assembly 1 has a main conveyor line 2, a receiving box 3, and a return conveyor line 4 on its side. The main conveyor line 2 is used to transport tea bags and allow them to smoothly enter the subsequent packaging station. The receiving box 3 is located below the main conveyor line 2 and can receive tea bags falling from the main conveyor line 2. The return conveyor line 4 is set between the receiving box 3 and the main conveyor line 2 and can transport the tea bags that have fallen into the receiving box 3 back to the main conveyor line 2.

[0036] Specifically, the receiving box 3 is fixedly mounted on the equipment assembly 1 and located below the main conveyor line 2. The width of the receiving box 3 gradually decreases from top to bottom, and the bottom of the receiving box 3 is open. The return conveyor line 4 includes a first conveyor line 41 and a second conveyor line 42. The first conveyor line 41 is partially located at the bottom of the receiving box 3, and its upper end extends above the front end of the conveyor line 2. The second conveyor line 42 is located below the first conveyor line 41 and between the first conveyor line 41 and the main conveyor line 2. It can be understood that when a tea bag falls from the main conveyor line 2 into the receiving box 3, it can pass through the open bottom of the receiving box 3 and fall onto the first conveyor line 41. The tea bag gradually moves upward with the first conveyor line 41 and eventually falls onto the second conveyor line 42, and is then conveyed back to the main conveyor line 2 by the second conveyor line 42, realizing the cyclical conveying of the tea bag.

[0037] The main conveyor line 2 includes multiple sets of conveyor rollers arranged sequentially in the horizontal direction. Each conveyor roller set includes multiple roller shafts 21 rotatably mounted on the equipment assembly 1 and a drive assembly for driving the multiple roller shafts 21 to rotate synchronously. In this embodiment, all roller shafts 21 are closely arranged in the horizontal direction. The roller shafts 21 are rubber-coated rollers, which have good frictional resistance and can better drive the tea bags to move. Each roller shaft 21 is inclined, and the end of the roller shaft 21 away from the equipment assembly 1 is higher than the end of the roller shaft 21 close to the equipment assembly 1. Based on this, when the tea bags move on the roller shafts 21, they can gradually move closer to the side of the equipment assembly 1, which can reduce the occurrence of tea bags falling into the receiving box 3 during normal conveying.

[0038] Reference Figure 2 The drive assembly is located inside the equipment assembly 1 and specifically includes a servo motor 22, a pulley (not shown in the figure), driven pulleys 23, and a transmission belt 24. The number of driven pulleys 23 is equal to the number of roller shafts 21 in a set of conveyor rollers, and each driven pulley 23 is fixedly installed at the end of a roller shaft 21. The servo motor 22 is fixedly mounted inside the equipment assembly 1, and the pulley is fixedly connected to the output end of the servo motor 22. The transmission belt 24 is wrapped around the outer periphery of the pulley and each driven pulley 23. Based on this, when the servo motor 22 operates to drive the pulley to rotate, the transmission belt 24 enables each driven pulley 23 to rotate synchronously and in the same direction, thereby enabling each roller shaft 21 in a set of conveyor rollers to rotate synchronously.

[0039] Furthermore, in this embodiment, by setting the rotational speed of the servo motor 22 in each group of drive components, the rotational speed of the servo motor 22 located at the front end of the main conveyor line 2 is lower than the rotational speed of the servo motor 22 located at the rear end of the main conveyor line 2. Based on this, the rotational speed of the roller 21 located at the front end of the main conveyor line 2 can always be lower than the rotational speed of the roller 21 located at the rear end of the main conveyor line 2. This is beneficial for the tea bags to gradually increase in speed when being conveyed on the main conveyor line 2, and can reduce the situation where the tea bags gradually accumulate at the rear end of the conveyor during the conveying process, resulting in stacking of materials.

[0040] Back Figure 1 The conveying front end of the main conveyor line 2 is equipped with an anti-jamming mechanism 5; refer to Figure 3 In this embodiment, the anti-jamming mechanism 5 is set as a material support plate 51, and the material support plate 51 is fixedly installed on the second conveyor line 42. The surface of the material support plate 51 is provided with multiple strip holes 52, and each roller shaft 21 passes through the corresponding strip hole 52 in a partial manner, so that the gap between adjacent roller shafts 21 can be blocked by the material support plate 51, thereby reducing the possibility of tea bags getting stuck in the gap between adjacent roller shafts 21 when the tea bags enter the main conveyor line 2.

[0041] Back Figure 1The equipment assembly 1 is equipped with a pushing mechanism 6, an anti-stacking mechanism 7, and a distributing mechanism 8 on one side. These mechanisms are arranged sequentially along the conveying direction of the tea bags. (Refer to...) Figure 4 The pushing mechanism 6 includes a brush roller 61, a first motor 62, and a second adjusting component 63. The brush roller 61 is fixedly mounted on the equipment assembly 1 via the second adjusting component 63. The second adjusting component 63 can be used to adjust the angle and installation position of the brush roller 61 so that the brush roller 61 is located outside one of the conveyor roller shafts 21. The first motor 62 is fixed to the second adjusting component 63, and the output end of the first motor 62 is coaxially connected to the brush roller 61. In use, by operating the first motor 62 to drive the brush roller 61 to rotate, the rotation direction of the brush roller 61 is opposite to the conveying direction of the main conveyor line 2. The brush roller 61 can push the tea bags accumulated at the front end of the conveyor to the outside of the main conveyor line 2, so that the tea bags fall into the receiving box 3 below.

[0042] It should be noted that, in this embodiment, the brush roller 61 is adjusted to a vertically inclined state during use. At this time, a material distribution area 64 for tea bags to pass through is formed between the brush roller 61 and the equipment assembly 1. The width of the material distribution area 64 is preferably equal to the width of the tea bag, or slightly larger than the width of the tea bag within a certain error range, so that the tea bags can pass smoothly through the material distribution area 64 for preliminary sorting. Furthermore, in this embodiment, using the brush roller 61 as a boundary, the roller shaft 21 located at the front end of the brush roller 61 along the tea bag conveying direction is designated as the first roller shaft 211, and the roller shaft 21 located at the front end of the brush roller 61 along the tea bag conveying direction is designated as the second roller shaft 212. The axial length of the first roller shaft 211 is greater than the axial length of the second roller shaft 212. The longer first roller shaft 211 can handle a larger number of tea bags at once, facilitating automated production of large quantities of tea bags.

[0043] Reference Figure 5 Multiple sets of anti-stacking mechanisms 7 are provided, and all anti-stacking mechanisms 7 are equidistantly arranged along the conveying direction of the main conveyor line 2. Specifically, the anti-stacking mechanism 7 includes a brush plate 71 and a first adjusting component 72. The brush plate 71 is fixedly mounted on the equipment assembly 1 by the first adjusting component 72, and the angle and installation position of the brush plate 71 can be adjusted by the first adjusting component 72. The brush plate 71 is always located above the roller 21, and can form a material passage area 73 with the roller 21 at intervals.

[0044] In use, the height of the material conveying area 73 is preferably equal to the thickness of a single tea bag, or slightly greater than the thickness of a single tea bag within a certain error range. When stacked tea bags pass through the material conveying area 73, the tea bags stacked on top can be separated from the tea bags below by the frictional resistance of the brush roller 61, thus allowing individual tea bags to pass through the material conveying area 73 in sequence. It can be understood that, due to the preliminary screening by the front-end anti-stacking mechanism 7, the number of tea bags located between the material distribution area 64 and the material conveying area 73 is controlled and relatively evenly distributed, which can greatly reduce the possibility of tea bags stacking and getting stuck in the material conveying area 73.

[0045] Simultaneously refer to Figure 4 The first adjustment component 72 and the second adjustment component 63 have basically the same structure and design principle, with the only difference being the change in installation position. Therefore, in this embodiment, the first adjustment component 72 is used as an example for explanation, while the second adjustment component 63 will not be described in detail.

[0046] Reference Figure 5 Specifically, the first adjustment assembly 72 includes a first connecting rod 721, a first adjusting block 722, a second connecting rod 723, and a second adjusting block 724. The first connecting rod 721 is vertically fixed to the side of the equipment assembly 1. The first adjusting block 722 is rotatably sleeved on the first connecting rod 721 and can rotate circumferentially around the central axis of the first connecting rod 721. The first adjusting block 722 has an insertion hole, and the second connecting rod 723 is matched and inserted into the inner side of the insertion hole. The second adjusting block 724 is rotatably sleeved on the second connecting rod 723, and the brush plate 71 is fixedly connected to the free end of the second adjusting block 724. In addition, the first adjusting block 722 and the first connecting rod 721, the second connecting rod 723 and the first adjusting block 722, and the second adjusting block 724 and the second connecting rod 723 are all fixed by locking members. Based on this, by adjusting the positions of the first adjusting block 722, the second connecting rod 723, and the second adjusting block 724, the specific position of the brush plate 71 in three-dimensional space can be changed.

[0047] The material separating mechanism 8 includes a fixed bracket 83, a roller 81, and a second motor 82. The fixed bracket 83 is fixed to the equipment assembly 1, while the roller 81 is rotatably mounted on the fixed bracket 83, with its axis perpendicular to the side of the equipment assembly 1. The second motor 82 is fixed to the fixed bracket 83, and its output end is coaxially connected to the roller 81. By controlling the operation of the second motor 82, the roller 81 can be rotated. In this embodiment, the roller 81 is located above the roller shaft 21, and the rotational speed of the roller 81 is always greater than that of the roller shaft 21 directly opposite it. Based on this, when the tea bag enters the area between the roller 81 and the conveyor roller group, it can be carried forward quickly by the roller 81, thereby performing a final separation of the tea bag and ensuring that the tea bags entering the packaging end are strictly counted as single items.

[0048] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
