Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a heat exchanger plate installation and flipping device. Background Art

[0002] A detachable plate heat exchanger is composed of many thin plates stamped with corrugated shapes at certain intervals, sealed around by gaskets, and overlapped and pressed by a frame and a pressing member during installation. When installing the plate heat exchanger, the heat exchanger plates need to be stacked with the front and back sides facing each other to achieve heat exchange work. During the installation of the existing heat exchanger plates, it is often necessary for workers to observe the position of the sealing strips on the plates manually, resulting in too low installation efficiency. Moreover, when workers work for a long time or are inattentive, it is possible to install two adjacent heat exchanger plates in the same direction. If this situation occurs, it is difficult to detect in time and can only be found during subsequent sealing detection, and then rework is required. Content of the Utility Model

[0003] In order to overcome the deficiencies of the above-mentioned existing problems, the utility model provides a heat exchanger plate installation and flipping device.

[0014] All features disclosed in this specification, or all steps in any method or process disclosed, except mutually exclusive features and / or steps, may be combined in any manner.

[0015] Any feature disclosed in this specification (including any additional claims, abstract, and drawings) can be replaced by other equivalent or alternative features with a similar purpose, unless specifically stated. That is, unless specifically stated, each feature is only an example of a series of equivalent or similar features.

[0016] As Figures 1-3 shown, a heat exchanger plate installation and flipping device includes a first conveying device 1 and a second conveying device 2. A counting and detecting device 18 is fixedly connected to one side of the first conveying device 1. A flipping device is arranged between the first conveying device 1 and the second conveying device 2. The flipping device includes a fixed platform 3. On the top surface of the fixed platform 3, there is a flipping bracket 4. Inside the flipping bracket 4, there are several driven rollers 5. Clamping devices 19 are arranged on both sides of the driven rollers 5. On both sides of one side of the flipping bracket 4, there are fixedly connected rotating shafts 6. One end of each rotating shaft 6 is rotatably connected to a bearing seat 7. The bottom of the bearing seat 7 is fixedly connected to a slider 8. A chute 9 that cooperates with the slider 8 is opened on the fixed platform 3. The bottom of the slider 8 extends out of the fixed platform 3 and is fixedly connected through a connecting member 11. Below the connecting member 11, there is a moving sleeve 17 integrally formed with the connecting member 11. A linear driving device 12 is connected inside the moving sleeve 17. One side of the connecting member 11 is fixedly connected to a motor platform 13. A first motor 10 is installed on the motor platform 13. The moving end of the first motor 10 penetrates upward through the fixed platform 3 and is drivingly connected to the rotating shaft 6 through gears. A slot 14 for the linear movement of the moving end of the first motor 10 is opened on the fixed platform 3.

[0017] The linear driving device 12 includes a lead screw 15, which is driven by a second motor 16. The lead screw 15 extends into the moving sleeve 17. A thread that cooperates with the lead screw 15 is opened inside the moving sleeve 17.

[0018] The clamping device 19 includes a bottom plate 20. The top surface of the bottom plate 20 is flush with the top surface of the driven roller 5. A fixed plate 24 is fixedly connected to the inner top of the flipping bracket 4. A pressing plate 22 driven by a cylinder 21 is arranged between the bottom plate 20 and the fixed plate 24. The cylinder 21 is fixedly connected to the middle lower part of the fixed plate 24. Cushion layers 23 are arranged on the top surface of the bottom plate 20 and the bottom surface of the pressing plate 22. Guide rods 25 are fixedly connected to both sides between the bottom plate 20 and the fixed plate 24. The guide rods 25 penetrate through the pressing plate 22. When the heat exchanger plate needs to be flipped, the cylinder 21 drives the pressing plate 22 to press down to prevent the heat exchanger plate from displacing during flipping.

[0019] One side outside of the flipping bracket 4 as the axis is arc-shaped. An arc groove is opened at the corresponding position of the flipping part of the fixed plate 24 and the flipping bracket 4. Specific embodiments

[0020] When the heat exchanger plates at even positions are on the flipping device, the first conveyor belt 1 and the second conveyor belt 2 stop working. The air cylinder 21 drives the pressing plate 22 to press the heat exchanger plates. The first motor 10 drives the rotating shaft 6 to drive the flipping bracket 4 to rotate 180° upward around the rotating shaft 6 as the axis. After the flipping work is completed, the second motor 16 drives the lead screw 15 to drive the moving sleeve 17 and the flipping bracket 4 to move downward to return to the middle position of the fixed platform 3. The first conveyor belt 1 and the second conveyor belt 2 continue to work. When the next heat exchanger plate at an even position is on the flipping device, the first conveyor belt 1 and the second conveyor belt 2 stop working. The air cylinder 21 drives the pressing plate 22 to press the heat exchanger plates. The first motor 10 drives the rotating shaft 6 to drive the flipping bracket 4 to rotate 180° downward around the rotating shaft 6 as the axis. The second motor 6 drives the lead screw 15 to drive the moving sleeve 17 and the flipping bracket 4 to move upward to return to the middle position of the fixed platform 3, and so on in a cycle.

[0021] The design of this solution is ingenious. When the counting and detecting device is odd, the heat exchanger plates directly pass through the flipping device. When the counting and detecting device is even, the flipping device works to ensure that the heat exchanger plates are arranged in a positive and negative order after passing through the flipping device. When the subsequent installers carry out the installation, the steps of observing the front and back of the heat exchanger plates before installation can be reduced, the installation efficiency can be improved, and the possibility that the adjacent two heat exchanger plates may be installed in the same direction by the assembly workers during high-intensity work can be effectively reduced.

[0022] The present utility model is not limited to the foregoing specific embodiments. The present utility model extends to any new feature or any new combination disclosed in this specification, and any new method or process step or any new combination disclosed.
