[0052] As Figure 1As shown, in an embodiment, a conveying mechanism 1000 is provided, which can be used to convey products. Among them, the products can be, but are not limited to, items such as bottled beverages, canned beverages, bottled seasonings, or boxed masks.

[0053] As Figure 1 shown, the conveying mechanism 1000 includes at least two groups of conveyor belt units 100, several transition roller units 200, and several control switches 300. Among them, a group of transition roller units 200 is arranged between any two adjacent groups of conveyor belt units 100.

[0054] In some embodiments, the conveyor belt unit 100 is configured with a conveying direction M. The conveyor belt unit 100 may include a first end 101 and a second end 102 arranged in sequence along the conveying direction M. Among them, the second end 102 is located downstream of the first end 101. In the embodiment, the conveying direction M of each conveyor belt unit 100 can be set to be the same, or arranged in sequence along the counterclockwise or clockwise direction. A first gap 401 is configured between the second end 102 of the conveyor belt unit 100 and the adjacent transition roller unit 200.

[0055] In the embodiment, the control switch 300 has an emergency stop function. The number of control switches 300 can be the same as the number of transition roller units 200. The control switches 300 can be correspondingly arranged on one side of a plurality of first gaps 401 one by one. And the control switch 300 can be electrically connected to the conveyor belt unit 100 upstream of its own first gap 401.

[0056] Thus, when an operator's finger is about to be caught in the first gap 401 between the conveyor belt unit 100 and the adjacent transition roller unit 200 due to operation errors or other reasons, the operator can promptly press the control switch 300 on one side of the first gap 401 to control the corresponding conveyor belt unit 100 to stop running. Thus, it can avoid the safety accident of the operator's finger being caught in the first gap 401 and ensure the safety of the operator.

[0057] As Figure 1 and Figure 7 shown, in some embodiments, the conveying mechanism 1000 may include five groups, six groups, eight groups or other numbers of conveyor belt units 100. Multiple groups of conveyor belt units 100 can be linearly distributed as needed, or distributed in a clockwise or counterclockwise direction or the like.

[0058] In the embodiment, the structures of each conveyor belt unit 100 can be set to be similar, and the connection methods between two adjacent conveyor belt units 100 can also be set to be similar. In the embodiment, the first conveyor belt unit 110 and the second conveyor belt unit 120 are taken as examples for detailed description.

[0059] In an embodiment, a transition roller unit 200 is provided between the first conveyor belt unit 110 and the second conveyor belt unit 120.

[0060] As Figures 1 to 4 shown, in some embodiments, the first conveyor belt unit 110 may include a first mounting frame 112, conveyor rollers 114, a driving assembly 113, and a conveyor belt 111.

[0061] Among them, the first mounting frame 112 may include a first support leg structure 1121 and two bearing beams 1122. Among them, the bearing beams 1122 may be of a hollow structure. The two bearing beams 1122 are arranged opposite to each other at intervals and may be fixedly installed on the first support leg structure 1121 by means of screw connection or welding. In the embodiment, the two bearing beams 1122 are both parallel to the conveying direction M of the first conveyor belt unit 110.

[0062] The first conveyor belt unit 110 includes a plurality of conveyor rollers 114. The plurality of conveyor rollers 114 are all rotatably installed between the two bearing beams 1122, and the plurality of conveyor rollers 114 may be arranged at intervals in sequence along the conveying direction M. In the embodiment, the rotation axis of the conveyor roller 114 may be perpendicular to the bearing beam 1122. In addition, one side of the bearing beam 1122 facing the conveyor roller 114 may be configured to be open. The two ends of the conveyor roller 114 may be inserted into the two bearing beams 1122 one by one and rotatably connected to the bearing beam 1122.

[0063] The conveyor belt 111 may be sleeved on the plurality of conveyor rollers 114. The driving assembly 113 may be in transmission connection with the plurality of conveyor rollers 114. During use, the driving assembly 113 may drive each conveyor roller 114 to rotate, and then the plurality of conveyor rollers 114 may drive the conveyor belt 111 to run along the conveying direction M to realize the conveying of products.

[0064] In some embodiments, the driving assembly 113 may include a driving member 1131, a first transmission chain 1132, and a first sprocket 1133. In the embodiment, two first sprockets 1133 are fixedly installed on each conveyor roller 114. The two first sprockets 1133 are respectively arranged at both ends of the conveyor roller 114, and the first sprocket 1133 may be arranged inside the corresponding end bearing beam 1122. Two first transmission chains 1132 may be provided. One of the first transmission chains 1132 is sleeved on the first sprockets 1133 at the same end of the plurality of conveyor rollers 114 and meshed with each first sprocket 1133. The other first transmission chain 1132 may be sleeved on the first sprockets 1133 at the other end of the plurality of conveyor rollers 114 and meshed with the first sprockets 1133 at this end.

[0065] In some other embodiments, only one first sprocket 1133 may be provided on each conveying roller 114. Each first sprocket 1133 is disposed at the end of the conveying roller 114 where it is located, and each first sprocket 1133 is disposed close to the same bearing beam 1122. The driving assembly 113 may include a first transmission chain 1132. The first transmission chain 1132 may be sleeved on each first sprocket 1133 and meshed with each first sprocket 1133.

[0066] In some embodiments, the driving member 1131 may be selected as a motor. The driving member 1131 may be fixedly installed on the first mounting frame 112. The driving member 1131 may be in transmission connection with one of the conveying rollers 114. Thus, the driving member 1131 can drive the conveying roller 114 to rotate, and then through the cooperation of the first transmission chain 1132 and each first sprocket 1133, the other conveying rollers 114 can be driven to rotate, and then the conveyor belt 111 can be driven to run along the conveying direction M.

[0067] In some embodiments, the driving assembly 113 further includes a second transmission chain 1134 and two second sprockets 1135. One of the second sprockets 1135 is fixedly connected to the output shaft of the driving member 1131. The other second sprocket 1135 may be fixedly connected to a conveying roller 114. The second transmission chain 1134 may be sleeved on the two second sprockets 1135 and meshed with the two second sprockets 1135. During the working process, the driving member 1131 can drive the conveying roller 114 provided with the second sprocket 1135 to rotate through the second transmission chain 1134 and the second sprocket 1135, and then the conveying roller 114 can drive the first transmission chain 1132 to rotate.

[0068] In some embodiments, the first conveyor belt unit 110 further includes a first protective member 1151 and a second protective member 1152.

[0069] Among them, two first protective members 1151 may be provided. The two first protective members 1151 are respectively disposed at the positions of the two bearing beams 1122. Taking one of the first protective members 1151 as an example for detailed description.

[0070] In the embodiment, the first protective member 1151 may be in a plate-like structure or a housing-like structure. The first protective member 1151 may be relatively fixed on the first mounting frame 112 and located on the side of the bearing beam 1122 where it is located towards the axial center of the conveying roller 114. The projection of the meshing point of the first transmission chain 1132 and the first sprocket 1133 in the bearing beam 1122 along the axis of the conveying roller 114 falls on the first protective member 1151. Correspondingly, the first protective member 1151 can shield and protect the meshing point of the first transmission chain 1132 and the first sprocket 1133 to prevent the operator from touching and causing a safety accident.

[0071] In addition, the first protection member 1151 is provided with a plurality of avoidance holes 11511 for the conveying rollers 114 to pass through, and the plurality of conveying rollers 114 can pass through the plurality of avoidance holes 11511 one by one. Moreover, a gap is arranged between the inner wall of the avoidance hole 11511 and the conveying roller 114 to prevent the first protection member 1151 from interfering with the rotation of the conveying roller 114, thereby ensuring that the conveying roller 114 can rotate smoothly.

[0072] In some embodiments, the second protective member 1152 may also be a plate-like structure or a cover-like structure. Two second protective members 1152 may be provided, and the two second protective members 1152 are arranged on both sides of the second transmission chain 1134 facing away from each other. And the second protective member 1152 may extend from one end of the second transmission chain 1134 close to the driving member 1131 to one end close to the conveying roller 114 connected to the second transmission chain 1134. In the embodiment, the meshing point of the second transmission chain 1134 and any second sprocket 1135, the projection along the axial direction of the conveying roller 114 is located on the second protective member 1152 on the corresponding side. Therefore, the meshing point of the second transmission chain 1134 and the second sprocket 1135 can be shielded and protected by the second protective member 1152 to prevent the operator from touching it and causing safety hazards.

[0073] In some embodiments, the end of the load-bearing beam 1122 is configured as an open structure. The conveyor belt unit 100 further includes a protective net 1153, which can be connected to the load-bearing beam 1122 by screw connection or clamping and can cover the open structure at the end of the load-bearing beam 1122, thereby preventing the operator from touching the running first transmission chain 1132 due to misoperation and other reasons, and avoiding being involved in the meshing position of the first transmission chain 1132 and the first sprocket 1133 to cause a safety accident.

[0074] In the embodiment, the structure of the second conveying roller 114 unit may be similar to the structure of the first conveying roller 114 unit, and will not be described in detail herein.

[0075] like Figure 1 , Figures 3 to 5 As shown, in some embodiments, the transition roller unit 200 may include a first sub-transition roller unit 210 and a second sub-transition roller unit 220 , wherein the first sub-transition roller unit 210 may be disposed close to the first conveyor belt unit 110 .

[0076] In some embodiments, the first sub-transition roller unit 210 includes a second mounting frame 211 and a plurality of transition rollers 212 .

[0077] Among them, the second mounting bracket 211 can be fixedly connected to the first mounting bracket 112 in the first conveyor belt unit 110 by means of screw connection or the like. In the embodiment, a first gap 401 is arranged between the first conveyor belt unit 110 and the first sub-transition roller unit 210. In some embodiments, the first gap 401 can be formed between the conveyor belt 111 in the first conveyor belt unit 110 and the second mounting bracket 211 in the first sub-transition roller unit 210. The width n1 of the first gap 401 can be set such that 3 mm ≤ n1 ≤ 5 mm. Thus, while ensuring the smooth operation of the conveyor belt 111, the gap between the first conveyor belt unit 110 and the first transition roller unit 200 can be minimized, and the risk that the operator's finger is caught in the first gap 401 can be reduced. Exemplarily, in some embodiments, the width n1 of the first gap 401 can be set to 3 mm, 3.2 mm, 3.5 mm, 3.8 mm, 4.1 mm, 4.3 mm, 4.5 mm, 4.7 mm, 5 mm or any other value between 3 mm and 5 mm.

[0078] In the embodiment, the control switch 300 between the first sub-transition roller unit 210 and the first conveyor belt unit 110 can be fixedly installed on one side of the second mounting bracket 211 in the first sub-transition roller unit 210 or on one side of the first mounting bracket 112 in the first conveyor belt unit 110 through structures such as a connecting plate. When an emergency occurs, the operator can press the control switch 300 to control the corresponding first conveyor belt unit 110 to stop urgently. In some embodiments, the control switch 300 also has a reset switch function. After the emergency is cancelled, the operator can press the control switch 300 again to control the first conveyor belt unit 110 to restart.

[0079] The second mounting bracket 211 can include a second support leg structure (not shown in the figure) and a carrier 2111. The carrier 2111 can be fixedly installed on the second support leg structure. In some embodiments, the carrier 2111 can be in an E shape, and a plurality of transition rollers 212 can be evenly distributed at two cavity positions of the carrier 2111 and rotatably connected to the carrier 2111. In the embodiment, a gap can be arranged between adjacent two transition rollers 212, which can ensure the smooth rotation of the transition rollers 212. In addition, the rotation axis of the transition roller 212 can be parallel to the rotation axis of the conveying roller 114. When the product passes through the first sub-transition roller unit 210, the transition roller 212 can be driven to rotate, so that the resistance during the movement of the product can be reduced, and the smooth transportation of the product can be realized.

[0080] In some other embodiments, the carrier 2111 can also be in a shape such as a Chinese character 'Ri'.

[0081] In some embodiments, the second sub-transition roller unit 220 may be symmetrically arranged with respect to the first sub-transition roller unit 210. The second mounting bracket 211 in the second sub-transition roller unit 220 may be fixedly connected to the second mounting bracket 211 in the first sub-transition roller unit 210 by means of screw connection or the like. A third gap 403 is provided between the transition roller 212 in the second sub-transition roller unit 220 and the transition roller 212 in the first sub-transition roller unit 210. The width n3 of the third gap 403 is set such that 3 mm ≤ n3 ≤ 5 mm. On the one hand, it can ensure that the transition rollers 212 close to each other in the first sub-transition roller unit 210 and the second sub-transition roller unit 220 can rotate smoothly. On the other hand, it can also reduce the possibility that an operator's finger or the like is caught in the third gap 403 due to misoperation, thereby enhancing the operation safety. Exemplarily, in some embodiments, the width n3 of the third gap 403 may be set to 3 mm, 3.2 mm, 3.5 mm, 3.8 mm, 4.1 mm, 4.3 mm, 4.5 mm, 4.7 mm, 5 mm or any other value within the range of 3 mm to 5 mm.

[0082] In some embodiments, the second mounting bracket 211 in the second sub-transition roller unit 220 and the first mounting bracket 112 in the second conveyor belt unit 120 may be fixedly connected by means of screw connection or the like. A second gap 402 is provided between the second conveyor belt unit 120 and the second sub-transition roller unit 220. In some embodiments, the second gap 402 may be formed between the second mounting bracket 211 in the second sub-transition roller unit 220 and the conveyor belt 111 in the second conveyor belt unit 120. The width n2 of the second gap 402 is set such that 3 mm ≤ n2 ≤ 5 mm. On the one hand, it can ensure the smooth operation of the conveyor belt 111 in the second conveyor belt unit 120. On the other hand, the second gap 402 between the second sub-transition roller unit 220 and the second conveyor belt unit 120 can be reduced, thereby reducing the possibility that an operator's finger or the like is caught in the second gap 402 due to misoperation and enhancing the operation safety. Exemplarily, in some embodiments, the width n2 of the second gap 402 may be set to 3 mm, 3.2 mm, 3.5 mm, 3.8 mm, 4.1 mm, 4.3 mm, 4.5 mm, 4.7 mm, 5 mm or any other value within the range of 3 mm to 5 mm.

[0083] As Figure 1 and Figure 6As shown, in some embodiments, the transition roller unit 200 may include a second sub-transition roller unit 220 and a connecting roller 213. Among them, the connecting roller 213 may be rotatably disposed between the second sub-transition roller unit 220 and the first conveyor belt unit 110. Accordingly, a first gap 401 may be formed between the connecting roller 213 and the conveyor belt 111 in the first conveyor belt unit 110. A fourth gap 404 is configured between the connecting roller 213 and the transition roller 212 in the second sub-transition roller unit 220, and the width n4 of the fourth gap 404 may be set such that 3 mm ≤ n4 ≤ 5 mm. On the one hand, the smooth rotation of the connecting roller 213 and the transition roller 212 in the second sub-transition roller unit 220 can be ensured, and on the other hand, the possibility that an operator's finger or the like is caught in the fourth gap 404 due to misoperation can be reduced. Exemplarily, in some embodiments, the width n4 of the fourth gap 404 may be set to 3 mm, 3.2 mm, 3.5 mm, 3.8 mm, 4.1 mm, 4.3 mm, 4.5 mm, 4.7 mm, 5 mm or any other value between 3 mm and 5 mm.

[0084] As Figure 1 and Figure 7 As shown, the conveying mechanism 1000 further includes a first terminal structure 510. In some embodiments, the first terminal structure 510 may be formed at one end of the conveyor belt unit 100. Additionally, the conveying mechanism 1000 further includes a third protective member 610, and the third protective member 610 may be a structure such as a protective plate or a protective rod. The third protective member 610 is disposed on a side of the first terminal structure 510 away from the other end of the conveyor belt unit 100 where it is located, and the third protective member 610 may be spaced apart from the first terminal structure 510 and form a fifth gap 405. In some embodiments, the width n5 of the fifth gap 405 between the third protective member 610 and the first terminal structure 510 may be set such that 120 mm ≤ n5 ≤ 200 mm, which can avoid forming a meshing point and causing potential safety hazards. In some embodiments, the width n5 of the fifth gap 405 between the third protective member 610 and the first terminal structure 510 may be set to 120 mm, 135 mm, 150 mm, 165 mm, 170 mm, 182 mm, 190 mm, 198 mm, 200 mm or any other value between 120 mm and 200 mm, etc.

[0085] In some embodiments, the conveying mechanism 1000 further includes a second terminal structure 520. In some embodiments, the second terminal structure 520 can be formed at one end of a conveyor belt unit 100 and is different from the installation position of the first terminal structure 510. The conveying mechanism 1000 further includes a housing structure 620, and the housing structure 620 can be fixedly installed at the end of the first mounting bracket 112 in the conveyor belt unit 100 by means of screw connection or the like. In the embodiment, a sixth gap 406 is provided between the housing structure 620 and the conveyor belt 111 in the conveyor belt unit 100, and the width n6 of the sixth gap 406 can be set such that 3 mm ≤ n6 ≤ 5 mm. Thus, while ensuring the smooth operation of the conveyor belt 111 in the conveyor belt unit 100, the gap between the conveyor belt unit 100 and the housing structure 620 can be minimized, and the risk of an operator's finger being caught in the sixth gap 406 can be reduced. Exemplarily, in some embodiments, the width n6 of the sixth gap 406 can be set to 3 mm, 3.2 mm, 3.5 mm, 3.8 mm, 4.1 mm, 4.3 mm, 4.5 mm, 4.7 mm, 5 mm, or any other value between 3 mm and 5 mm.

[0086] In the implementation of this application, the connection gap between the conveyor belt unit 100 and the transition roller unit 200, as well as the meshing points between the drive chain and the sprocket, can be blocked and eliminated, which can reduce the probability that an operator's finger or the like is caught in the connection gap and the meshing points due to misoperation or other reasons, thereby reducing the probability of potential safety hazards, improving the operational safety during product conveying, and ensuring the personal safety of the operator.
