Description

Technical Field

[0001] The invention relates to the technical field of conveying and pulling chains, in particular to a conveying and pulling chain device. Background Art

[0002] The chain conveyor can meet the single-row conveying requirements of beverage labeling, filling, cleaning and other equipment. It can also convert a single row into multiple rows and move slowly, thereby generating storage capacity to meet the large-scale feeding requirements of sterilizers, bottle storage tables, and bottle coolers. We can make the head and tail of the two chain conveyors into overlapping mixed chains, so that the bottle body is in a dynamic transition state, so that no bottles are retained on the conveyor line, which can meet the pressure and pressure-free conveying of empty and full bottles.

[0003] In the prior art, the conveying traction chain mainly uses the chain as a traction and carrier. The power provided by the driving device makes the chain rotate, thereby driving the material to move along the specified path. The conveying traction chain is mainly composed of a driving device, a chain, a carrying device, and a guide device. The driving device is usually an electric motor, which provides power to the chain to start continuous or intermittent transmission. The chain, as the main transmission mechanism, starts to move under the action of the driving device. The carrying device is responsible for carrying and conveying materials. The materials are placed on the carrying device. With the movement of the chain, the materials are continuously transported from one position to another. The guide device ensures that the material maintains the correct direction during the conveying process to prevent it from deviating from the track.

[0004] The publication number of the comparative patent document is: "CN202210356777.6 A traction chain, comprising a traction segment and a connecting segment, wherein the traction segments are evenly distributed between the connecting segments, and the connecting segments and the traction segments are connected to each other through inner chain plates, and a traction portion protrudes downward from the bottom of the traction segment, and a traction hook is hinged on the traction portion, and the surface on which the traction hook rotates is a vertical plane. One purpose of the invention is to use a movable traction hook to replace the original push head, so that the traction hook and the trolley are relatively flexibly connected to avoid direct collision and extrusion, greatly reduce wear during use, and help to increase the service life of the chain and the trolley; and the traction hook is convenient for replacement and maintenance, and the replacement of the traction hook can be completed without disassembling the entire traction chain." The above patent document mainly solves the problem of convenient replacement of the traction hook, but fails to solve the problem of adjusting the chain tension and facilitating the maintenance of the chain. Therefore, this application proposes a conveying traction chain device to solve the problem of adjusting the chain tension and facilitating the maintenance of the chain.

[0005] At present, for the conveying and traction chain device, during long-term operation, it is necessary to regularly adjust the tension of the chain, and maintenance is crucial. The existing conveying and traction chains are difficult to control the chain tension, which affects the service life and usage effect of the chain. Maintaining the surface of the chain not only wastes working time but also is not ideal for the cleaning and maintenance effect of the chain. Therefore, we propose a conveying and traction chain device. Summary of the Invention

DETAILED DESCRIPTION OF THE INVENTION

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] Embodiment 1: Please refer to Figures 1-9 , a conveying and traction chain device shown in the figure, including a frame 1 made of a rigid metal material, which can then bear the pressure value generated during the conveying operation. Two drive shafts 2 are rotatably connected to one side of the frame 1. A chain a4 is meshed and connected to the outside of the two drive shafts 2 through a sprocket a3. A guide groove 16 is fixed to one side of the frame 1. The chain a4 is in contact with the inner side of the guide groove 16. The guide groove 16 forms a guiding and traction effect on the chain a4, which can then reduce the slack caused by excessive sagging during the operation of the chain a4. A baffle 17 is fixed to the outside of the frame 1. The baffle 17 is located on one side of the chain a4. The baffle 17 is arranged in a concave shape, which then forms a blocking effect on the conveying area to prevent the goods from falling and being damaged during the conveying operation. The chain a4 is driven to operate through the meshing transmission of the sprocket a3 and the chain a4; it further includes a driving unit 5 arranged on one side of the frame 1, and the driving unit 5 is used to drive the chain a4 to work; a tensioning unit 6 arranged on one side of the frame 1, and the tensioning unit 6 is adapted to the chain a4, and the tensioning unit 6 is used to adjust the tension of the chain a4.

[0043] It should be noted that a threaded sleeve 10 is fixed to the outside of the frame 1. A screw rod 11 is threadedly connected to the threaded sleeve 10. One end of the screw rod 11 is rotatably connected to a support base 12, and the other end of the screw rod 11 is fixed with a rotating wheel 13. By rotating the corresponding rotating wheel 13, the height position of the frame 1 can be adjusted, so that the frame 1 can be applied to different site application scenarios.

[0044] In this solution, one of the drive shafts 2 is driven to rotate through the driving unit 5, and then the sprocket a3 is driven to rotate synchronously. By using the meshing transmission effect between the sprocket a3 and the chain a4, the chain a4 is then driven to move at a constant speed after being stressed, for the conveying operation of the goods.

[0045] Among them, the driving unit 5 includes a reduction motor 51. The reduction motor 51 is arranged on one side of the frame 1. By setting the reduction motor 51, due to the high overload capacity of the reduction motor 51, it has a wide range of adaptability, can also improve the transmission efficiency of the chain a4, effectively reduce energy consumption. A sprocket b52 is arranged between the output shaft of the reduction motor 51 and the driving shaft 2. The two sprockets b52 are meshed and driven by a chain b53. The transmission of the sprocket b52 and the chain b53 can be applied to a heavy-duty transmission environment. While transmitting a large power, it has a strong overload capacity and is suitable for occasions that need to bear a large load.

[0046] The working principle of the driving unit 5: As Figure 1 、 Figure 2 、and Figure 8 shown, through the drive of the reduction motor 51, the sprocket b52 rotates synchronously. By using the meshing and driving effect between the sprocket b52 and the chain b53, the driving shaft 2 is driven to rotate synchronously, so that the sprocket a3 rotates synchronously. By using the meshing and driving effect between the sprocket a3 and the chain a4, the chain a4 runs smoothly to convey the goods smoothly.

[0047] Embodiment 2: Please refer to Figure 3 、 Figure 4 、 Figure 5 and Figure 9 , this embodiment further illustrates Embodiment 1. The difference lies in optimizing the frame 1 and adding a tensioning unit 6 for adjusting the tension of the chain a4;

[0048] Specifically, the tensioning unit 6 includes a support plate 61. The material of the support plate 61 is set as a hard metal material. The support plate 61 is fixed on one side of the frame 1, and the included angle between the support plate 61 and the frame 1 is set at a right angle. A cylinder 62 is fixed at the top of the support plate 61. The most preferred number value of the cylinder 62 is two. Similarly, one cylinder 62 can also achieve the purpose of adjusting the tension of the chain a4. However, when the number of cylinders 62 is set to two, the connecting plate a63 can be pushed smoothly. The output end of the cylinder 62 is fixed with a double-sided rack plate 64 through the connecting plate a63;

[0049] A bracket 65 is fixed on one side of the double-sided rack plate 64. A guide frame a9 is fixed on one side of the frame 1. The bracket 65 is slidably penetrated through the guide frame a9. The guide frame a9 is used for guiding the bracket 65. The guide frame a9 is composed of two guide rods, and the bracket 65 is slidably penetrated through the guide rods of the guide frame a9, so as to be able to play a guiding role for the bracket 65 and improve the stability of the bracket 65 when moving under force. A guide roller 66 is rotatably connected to one side of the bracket 65, and the guide roller 66 is in contact with the sprocket a3. The guide roller 66 is used for adjusting the tension of the chain a4.

[0050] It should be noted that the material of the guide roller 66 is a hard rubber roller. When the tension of the chain a4 does not need to be adjusted, the guide roller 66 can support the chain a4, and then realize the guiding of the chain a4, which can effectively improve the stability of the chain a4 during operation. When the tension of the chain a4 needs to be adjusted, by squeezing the guide roller 66 and the chain a4, the tension adjustment work of the chain a4 can be quickly completed.

[0051] In this solution, when the tension of the chain a4 needs to be adjusted, the tension adjustment principle of the tensioning unit 6 for the chain a4 is as follows: Figure 3 、 Figure 4 、 Figure 5 and Figure 9 As shown, through the drive of the air cylinder 62, the connecting plate a63 moves synchronously, and then drives the two double-sided rack plates 64 to move, so that the bracket 65 moves synchronously with the double-sided rack plate 64, causing the guide roller 66 to move synchronously. By using the contact between the guide roller 66 and the chain a4, and the extrusion effect between the guide roller 66 and the chain a4, the purpose of adjusting the tension of the chain a4 is achieved.

[0052] Embodiment Three: Please refer to Figure 4 、 Figure 6 and Figure 8 This embodiment further illustrates Embodiment One. The difference lies in optimizing the drive unit 5 and the adjustment unit 7 adjusting the tension of the chain b53;

[0053] Specifically, an adjustment unit 7 adapted to the drive unit 5 is provided on one side of the frame 1. The adjustment unit 7 includes a guide rail 71, and the guide rail 71 is fixed on one side of the frame 1. The shape of the guide rail 71 is set in an L shape, which can provide good support for the reduction motor 51 and effectively improve the stability of the reduction motor 51 during translation. The reduction motor 51 slides in the guide rail 71 through the base plate 72, and the sliding of the base plate 72 in the guide rail 71 provides a guiding function for the reduction motor 51;

[0054] A bearing seat 73, the bearing seat 73 is fixed on one side of the frame 1. The most preferred number of the bearing seats 73 is two, with lower cost and better effect. A lead screw 74 rotates in the bearing seat 73. A support frame 75 is fixed on one side of the frame 1, and a servo motor 76 is fixed on one side of the support frame 75. The cross-sectional shape of the support frame 75 is set in an L shape, which can effectively support the servo motor 76 and then greatly improve the stability of the servo motor 76 during driving. One end of the output shaft of the servo motor 76 is fixed to the lead screw 74, and the lead screw 74 is fixed to the base plate 72 through a lead screw sleeve 77, and the lead screw 74 is in threaded transmission with the lead screw sleeve 77.

[0055] It should be noted that by adopting the setting of the servo motor 76, a very precise motion control effect can be achieved, with high-precision closed-loop control, so as to effectively and accurately adjust the tension of the chain b53, and then prevent the transmission failure caused by the chain b53 being too loose.

[0056] Embodiment 4: Please refer to Figure 3 、 Figure 7 and Figure 8 , this embodiment further describes Embodiment 1. The difference lies in optimizing the tensioning unit 6 and cleaning and maintaining the chain a4 through the cleaning unit 8;

[0057] Specifically, a cleaning unit 8 adapted to the tensioning unit 6 is provided on one side of the frame 1. The cleaning unit 8 includes a rotating seat 81 fixed to one side of the frame 1. The number of the rotating seats 81 is most preferably four, which can carry two rotating shafts 82 with the least number of selections. A rotating shaft 82 is rotatably connected in the rotating seat 81. The rotating shaft 82 is meshed with the double-sided rack plate 64 through a spur gear 83. Through the power conversion of the rotating shaft 82, when the double-sided rack plate 64 moves upward, the single-sided rack plate 84 moves downward;

[0058] The single-sided rack plate 84 is meshed with the spur gear 83. The two single-sided rack plates 84 are fixed by a connecting plate b85. The included angle between the connecting plate b85 and the single-sided rack plate 84 is a right angle, which can ensure the synchronous movement of the two opposite single-sided rack plates 84. A mounting frame 86 is fixed on one side of the connecting plate b85. A roller 87 is rotatably connected in the mounting frame 86. A brush belt 88 is sleeved outside the roller 87, and the brush belt 88 is used for cleaning and maintaining the chain a4.

[0059] It should be noted that a guide frame b14 is fixed on one side of the frame 1. The mounting frame 86 is slidably penetrated through the guide frame b14. The guide frame a9 is located between the guide frames b14. Through the sliding penetration between the mounting frame 86 and the guide frame b14, the guiding effect on the mounting frame 86 is achieved, and the stability of the mounting frame 86 when moving under force can be effectively improved, preventing the mounting frame 86 from shaking and shifting when moving.

[0060] Among them, limit rings 15 are fixed at one ends of the guide frame a9 and the guide frame b14. The limit rings 15 are in a hexagonal shape. The diameter value of the limit rings 15 is greater than the diameter value of the guide rod at the guide frame b14, effectively forming a limit on the guide frame a9 and the guide frame b14, preventing the situation of falling off due to the excessive movement of the mounting frame 86 and the bracket 65.

[0061] In this solution, when the chain a4 is required to convey items;

[0062] First, driven by the reduction motor 51, the sprocket b52 rotates. By the meshing drive between the sprocket b52 and the chain b53, one of the drive shafts 2 rotates synchronously, driving the sprocket a3 to operate. Through the meshing drive between the sprocket a3 and the chain a4, the chain a4 is then driven to operate;

[0063] Secondly, when the tension of the chain b53 needs to be adjusted, driven by the servo motor 76, the lead screw 74 rotates synchronously. By the screw drive between the lead screw 74 and the nut sleeve 77, the substrate 72 is forced to slide within the guide rail 71, and then drives the substrate 72 and the servo motor 76 to move synchronously, causing the sprocket b52 fixed to the servo motor 76 to move synchronously, achieving the purpose of adjusting the tension of the chain b53;

[0064] Then, after long-term use, when the tension of the chain a4 needs to be adjusted, driven by the cylinder 62, the connecting plate a63 is forced to rise, driving the double-sided rack plate 64 to move synchronously, and then driving the bracket 65 to move synchronously, causing the guide roller 66 to move synchronously. By the extrusion of the guide roller 66 and the chain a4, the tension adjustment of the chain a4 is completed;

[0065] Finally, through the meshing drive between the double-sided rack plate 64 and the spur gear 83, and the meshing drive between the spur gear 83 and the single-sided rack plate 84, when the double-sided rack plate 64 moves upward, the single-sided rack plate 84 moves downward, and then drives the mounting frame 86 to move synchronously, causing the brush belt 88 to move synchronously. The brush belt 88 contacts the chain a4, and driven by the chain a4, the cleaning and maintenance of the chain a4 are completed. Lubricating oil can be applied to one of the brush belts 88. After lubricating the chain a4, the excess oil is wiped off by the other brush belt 88.

[0066] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0067] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
