Description

Technical Field

[0001] This utility model relates to the field of tubular chain conveyor technology, and in particular to a tubular chain tensioning and buffering mechanism for a tubular chain conveyor. Background Technology

[0002] Tubular chain conveyors, also known as plate chain conveyors, are continuous conveying equipment for powders, small particles, and small-volume materials. They can achieve three-dimensional conveying in combination with horizontal, inclined, and vertical configurations. The working principle of a tubular chain conveyor is to use a chain as the transmission element to transport materials along a closed pipe. In conveying systems, they feature stable performance, energy saving, environmental friendliness, and sealing.

[0003] Patent application CN221776794U discloses a tensioning and buffering mechanism for a tubular chain conveyor. The mechanism includes a material plate with limiting chambers on both sides. A fixed plate is located in the center of each limiting chamber. A buffer spring is positioned between the fixed plate and the material plate. A connecting block is fixed to the outer side of the fixed plate, and a sponge gasket is fitted inside the connecting block. The connecting block extends beyond the limiting chambers, and a chain is threaded onto its outer end. This invention, through the combination of limiting chambers, fixed plates, buffer springs, and sponge gaskets, forms a tensioning and buffering mechanism. This provides both tension and buffering between the material plate and the chain, reducing the risk of damage or breakage during prolonged use and extending the service life of both the material plate and the chain in the tubular chain conveyor.

[0004] However, the tubular chain tensioning and buffering mechanism of this tubular chain conveyor has a buffer structure set in the material plate. During long-term use, the internal spring will gradually lose its elasticity due to repeated compression and stretching, and needs to be replaced in time. Since the material plate is not easy to disassemble, when it is necessary to replace the spring or repair the buffer structure, it will increase the maintenance difficulty and time cost. In order to address the above problems, we have introduced a tubular chain tensioning and buffering mechanism for tubular chain conveyors. Utility Model Content

[0005] This utility model discloses a tubular chain tensioning and buffering mechanism for a tubular chain conveyor. It studies and improves upon the existing structure and its shortcomings, providing a tubular chain tensioning and buffering mechanism for a tubular chain conveyor to achieve better practical value.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A tubular chain conveyor tensioning and buffering mechanism includes a material plate, with a first sleeve and a second sleeve slidably connected inside the material plate. Limiting rings are fixedly connected to the outer sides of both the first sleeve and the second sleeve, with one end of the limiting ring abutting against one side of the material plate. An installation groove is provided on one side of both the first sleeve and the second sleeve, and a connecting component and a buffer component are respectively provided inside the installation groove. A chain is provided on one side of the material plate.

[0008] The connecting assembly includes a fixing plate that is slidably connected inside the mounting groove. Mounting cylinders are fixedly connected at equal intervals to one side of the fixing plate, and screws are threaded into the interior of the mounting cylinders.

[0009] In a preferred embodiment, the buffer assembly includes a movable plate disposed inside the first sleeve and the second sleeve respectively. The interior of the movable plate is slidably connected to the exterior of the mounting cylinder, and a buffer spring is disposed on the exterior of the mounting cylinder.

[0010] In a preferred embodiment, a fixed cylinder is fixedly connected to one end of the movable plate, the outer side of the fixed cylinder is slidably connected to the inside of the fixed plate, and a threaded block is provided at one end of the chain, the outer side of the threaded block is threadedly connected to the inside of the fixed cylinder.

[0011] In a preferred embodiment, a positioning block is fixedly connected at equal intervals to one side of the first sleeve, and a positioning groove is provided at equal intervals on one side of the second sleeve, with the outer side of the positioning block slidingly connected to the inside of the positioning groove.

[0012] In a preferred embodiment, the first sleeve, the second sleeve, the limiting ring, the fixing plate, the mounting cylinder, the movable plate, and the fixing cylinder all have identical left and right structures.

[0013] The tubular chain tensioning and buffering mechanism for a tubular chain conveyor provided by this utility model has the following advantages:

[0014] Firstly, the detachable sleeve structure allows for quick disassembly and assembly of the structure within the material plate, enabling rapid replacement of the buffer spring. It also allows for replacement of the material plate as needed, increasing the equipment's maintenance flexibility.

[0015] Secondly, by using the mounting sleeve to restrict the movable plate, the chain rotation during use can be prevented from driving the movable plate to rotate inside the sleeve. This reduces the frictional resistance during the buffering process and also reduces the noise generated. Attached Figure Description

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0024] The tubular chain tensioning and buffering mechanism disclosed in this utility model is mainly used in tubular chain conveyor scenarios.

[0025] Reference Figures 1 to 6 A tubular chain conveyor tensioning and buffering mechanism includes: a material plate 1, a first sleeve 2 and a second sleeve 3 slidably connected inside the material plate 1, a limit ring 4 fixedly connected to the outer side of the first sleeve 2 and the second sleeve 3, one end of the limit ring 4 abutting against one side of the material plate 1, an installation groove 5 is provided on one side of the first sleeve 2 and the second sleeve 3, a connecting component and a buffer component are respectively provided inside the installation groove 5, and a chain 12 is provided on one side of the material plate 1;

[0026] The connecting assembly includes a fixing plate 6, which is slidably connected inside the mounting groove 5. Mounting cylinders 7 are fixedly connected at equal intervals on one side of the fixing plate 6, and screws 8 are threadedly connected inside the mounting cylinders 7.

[0027] The buffer assembly includes a movable plate 9, which is respectively disposed inside the first sleeve 2 and the second sleeve 3. The interior of the movable plate 9 is slidably connected to the outside of the mounting cylinder 7, and a buffer spring 11 is disposed on the outside of the mounting cylinder 7.

[0028] One end of the movable plate 9 is fixedly connected to a fixed cylinder 10, the outer side of the fixed cylinder 10 is slidably connected to the inside of the fixed plate 6, and one end of the chain 12 is provided with a threaded block 13, the outer side of the threaded block 13 is threadedly connected to the inside of the fixed cylinder 10.

[0029] The first sleeve 2 is fixedly connected to a positioning block 14 at equal intervals on one side, and the second sleeve 3 is provided with a positioning groove 15 at equal intervals on one side. The outer side of the positioning block 14 is slidably connected to the inside of the positioning groove 15.

[0030] In the above technical solution, considering that the tubular chain tensioning and buffering mechanism of the tubular chain conveyor has a buffer structure in the material plate, the internal spring will gradually lose its elasticity due to repeated compression and stretching during long-term use and needs to be replaced in time. Since the material plate is not easy to disassemble, when it is necessary to replace the spring or repair the buffer structure, it will increase the difficulty of maintenance and time cost. In order to solve this problem, the specific operation is as follows: By setting up a connecting component and a buffer component, when the buffer spring 11 gradually loses its elasticity due to repeated compression and stretching after the material plate 1 has been used for a long time and needs to be replaced in time, first rotate the material plate 1 to let the threaded block 13 exit from the fixed cylinder 10, place the material plate 1 horizontally, and use a tool to remove the multiple screws 8 from the mounting cylinder 7. Remove the first sleeve 2 and the second sleeve 3 simultaneously to separate them from both sides of the material plate 1. The buffer spring 11 can then be removed directly. Place the new spring in the mounting cylinder 7 at the bottom, and then put the first sleeve 2 and the second sleeve 3 on the material plate 1. Let the positioning block 14 enter the positioning groove 15. In this way, the two sets of mounting cylinders 7 are connected to form a whole, and the buffer spring 11 is sleeved on the outside of the mounting cylinder 7 and located between the two sets of movable plates 9. Tighten the screw 8 again to fix the first sleeve 2, the material plate 1 and the second sleeve 3. The new spring will push the movable plate 9 to one side, allowing the fixed cylinder 10 to extend out from the fixed plate 6. Tighten the threaded block 13 of the chain 12 into the fixed cylinder 10 to complete the replacement of the buffer spring 11. The detachable sleeve structure allows for quick disassembly and assembly of the structure in the material plate 1, enabling rapid replacement of the buffer spring 11. The material plate 1 can also be replaced as needed, increasing the equipment's maintenance flexibility. At the same time, the installation sleeve 7 restricts the movable plate 9, preventing the chain 12 from rotating during use and driving the movable plate 9 to rotate inside the sleeve. This reduces frictional resistance during buffering and also reduces noise.

[0031] Reference Figures 1 to 6In a preferred embodiment, the first sleeve 2, the second sleeve 3, the limiting ring 4, the fixing plate 6, the mounting cylinder 7, the movable plate 9, and the fixing cylinder 10 all have the same left and right structure;

[0032] Working principle: During use, after prolonged use, the buffer spring 11 gradually loses its elasticity due to repeated compression and stretching, requiring timely replacement. First, rotate the material plate 1 to remove the threaded block 13 from the fixing cylinder 10. Place the material plate 1 horizontally and use tools to remove the multiple screws 8 from inside the mounting cylinder 7. Then, simultaneously pull the first sleeve 2 and the second sleeve 3 to separate them from both sides of the material plate 1, allowing the buffer spring 11 to be removed directly. Place the new spring in the bottom mounting cylinder 7, and then put the first sleeve 2 and the second sleeve 3 onto the material plate 1, allowing the positioning block 1 to... 4. Enter the positioning groove 15, so that the two sets of mounting cylinders 7 are connected to form a whole, and the buffer spring 11 is sleeved on the outside of the mounting cylinder 7 and located between the two sets of movable plates 9. Tighten the screw 8 again to fix the first sleeve 2, the material plate 1 and the second sleeve 3. The new spring will push the movable plate 9 to one side, allowing the fixed cylinder 10 to extend out from the fixed plate 6. Tighten the threaded block 13 of the chain 12 into the fixed cylinder 10 to complete the replacement of the buffer spring 11. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0033] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
