[0035] like Figures 1 to 6The inner liner automatic microchannel winding device shown is used to wind the microchannel on the side wall of the inner liner 1. The device includes a translation mechanism, a lifting mechanism, a pressing and rotating mechanism and a tightening mechanism, wherein:

[0036] The translation mechanism is used to place the inner liner 1 and move the inner liner 1 to the top of the lifting mechanism and the bottom of the pressing and rotating mechanism;

[0037] A lifting mechanism, used for lifting the inner liner 1 so that the lower end of the inner liner 1 is higher than the upper end of the translation mechanism;

[0038] A tightening mechanism moves relative to the inner container 1 and tightens one side of the microchannel against the side wall of the inner container 1;

[0039] The pressing and rotating mechanism moves relative to the inner liner 1, pressing and rotating the inner liner 1 to drive the microchannel hung on the inner liner 1 to rotate relative to the pressing mechanism. The microchannel is squeezed on the side wall of the inner liner 1 when passing through the pressing mechanism along the side wall of the inner liner 1.

[0040] In the above technical solution, the translation mechanism is used to move the inner liner in and out; the lifting mechanism is used to lift the inner liner to facilitate the extrusion of the microchannel; the pressing and rotating mechanism is used to press the inner liner from above and rotate it. When rotating, the pressing mechanism simultaneously presses the microchannel. Therefore, when the microchannel passes through the pressing mechanism along the side wall of the inner liner 1, it is squeezed on the side wall of the inner liner 1 and firmly fits the side wall of the inner liner. Through this device, the assembly efficiency of the inner liner and the microchannel is greatly improved, the product quality is significantly improved, and the energy consumption is reduced (the heat transfer effect is good when the two sides are tightly fitted).

[0041] Furthermore, the translation mechanism includes a conveyor belt 2 arranged on both sides, a driving motor 3 for driving the conveyor belt 2 to move, and a tooling plate 4 mounted on the conveyor belt 2 on both sides. The inner liner 1 is placed on the tooling plate 4. The driving motor 3 can drive the conveyor belt 2 to move, thereby driving the tooling plate 4 and the inner liner 1 to move above the lifting mechanism.

[0042] Furthermore, a lifting circular hole 5 is provided in the middle of the tooling plate 4, and a circular cover plate 6 is provided on the lifting circular hole 5. A protruding block 8 is formed at the lower end of the circular cover plate 6 and extends into the lifting circular hole 5. The outer diameter of the circular cover plate 6 is larger than the inner diameter of the lifting circular hole 5, and the inner liner 1 is placed on the circular cover plate 6. In this technical solution, the provision of the lifting circular hole 5 facilitates lifting the inner liner and the circular cover plate, facilitates the winding of the microchannel, reduces interference, and at the same time, since the tooling plate is heavy, the pressure on the equipment can be reduced.

[0043] Furthermore, the lifting mechanism includes a lifting cylinder 7 and a lifting circular plate 9 arranged on the output end of the lifting cylinder 7, the lifting circular plate 9 is adapted to the lifting circular hole 5, and the lifting cylinder 7 can lift the lifting circular plate 9 out of the lifting circular hole 5 to lift the circular cover 6 and the inner tank 1.

[0044] Further, the clamping and rotating mechanism includes a frame 10, a lifting cylinder 11 disposed on the upper part of the frame 10, and a lifting frame 12 disposed on the output end of the lifting cylinder 11. The lifting frame 12 is provided with first sliders 13 on both sides of the back, and the frame 10 is provided with a first guide rail 14 adapted to the first slider 13. A connecting flange 15 is fixedly disposed below the lifting frame 12, and a rotating plate 16 is fixedly disposed at the lower end of the connecting flange 15. A plurality of clamping blocks 17 are fixedly disposed circumferentially at the lower end of the rotating plate 16. The rotating plate 16 is longitudinally arranged corresponding to the lifting circular plate 9. The lifting cylinder 11 can drive the lifting frame 12 to move longitudinally along the frame 10 so that the plurality of clamping blocks 17 move downward to clamp the upper part of the inner liner 1 or move upward away from the upper part of the inner liner 1. In this technical solution, the clamping part of the clamping and rotating mechanism, that is, the lifting cylinder 11, can drive the lifting frame 12 to move longitudinally along the frame 10 to clamp, and the longitudinal movement range is large, and it can adapt to inner liner of various sizes.

[0045] Furthermore, the pressing and rotating mechanism also includes a rotating motor 18 disposed on the lifting frame 12, and a driving gear 19 and an external gear slewing bearing 20 meshingly disposed in the lifting frame 12, wherein the driving gear 19 is disposed on the output end of the rotating motor 18, and the external gear slewing bearing 20 is fixedly connected to the upper part of the connecting flange 15, and the rotating motor 18 can drive the driving gear 19 to rotate and drive the external gear slewing bearing 20 to rotate so that the connecting flange 15, the rotating plate 16 and the plurality of clamping blocks 17 rotate circumferentially to drive the inner liner 1 to rotate. In this technical solution, the rotating motor drives the plurality of clamping blocks that have pressed the upper part of the inner liner to rotate circumferentially, thereby driving the inner liner to rotate, and then driving the microchannel hung on the inner liner to rotate.

[0046] Furthermore, the lower end surface of the clamping block 17 is an inclined surface or an arc surface that tilts downward from the inside to the outside. In this technical solution, the lower end surface of the clamping block is an inclined surface or an arc surface, which can make the clamping block have a good clamping effect and prevent radial movement within a certain range when the inner shell rotates.

[0047] Furthermore, a U-shaped fixing frame 21 is mounted on the upper portion of the clamping block 17, the two sides of the U-shaped fixing frame 21 are fixed to the two sides of the clamping block 17, and the upper end of the U-shaped fixing frame 21 is fixedly connected to the rotating plate 16. In this technical solution, the U-shaped fixing frame improves the structural connection strength between the rotating plate and the clamping block.

[0048] Furthermore, an L-shaped handle 22 is screwed on the upper part of the U-shaped fixing frame 21 and the rotating plate 16 above the rotating plate 16, and a gasket 23 is provided between the L-shaped handle 22 and the rotating plate 16. In this technical solution, the setting of the L-shaped handle facilitates the disassembly and assembly adjustment between the rotating plate and the clamping block.

[0049] Further, the tightening mechanism comprises a mounting frame 24, a mobile frame 25 arranged on the mounting frame 24, a roller 26 arranged at the front end of the mounting frame 24, and a push cylinder 27 installed on the mounting frame 24, wherein the mobile frame 25 is installed on the output end of the push cylinder 27, the mounting frame 24 is provided with a second guide rail 28, the mobile frame 25 is provided with a second slider 29 matched with the second guide rail 28, and the push cylinder 27 can push the mobile frame 25 so that the roller 26 tightens one side of the microchannel against the side wall of the liner 1 or retracts the mobile frame 25 so that the roller 26 releases the microchannel. In this technical solution, the roller tightens the microchannel, and when the microchannel rotates along the side wall of the liner, the roller contacts the roller, which also reduces friction and reduces wear on the microchannel. In addition, the roller is slightly backward and obliquely pressed on one side of the microchannel, and the extrusion effect is good. The push cylinder drives the mobile frame and the roller to move back and forth to cooperate with the guide rail and the slider, and the mobile structure is stable.

[0050] In this specific embodiment, the assembly of the inner tank and the microchannel in the existing heat pump water heater is manually assembled, which has low efficiency and cannot ensure that the microchannel heat exchanger as a whole is tightly fitted with the inner tank surface. The above scheme automates the step of winding the microchannel on the inner tank so that the microchannel is automatically wound on the side wall of the inner tank. Specifically, the translation mechanism is used to move the inner tank in and out; a lifting mechanism is provided to lift the inner tank to facilitate the extrusion of the microchannel; a pressing and rotating mechanism is provided to press the inner tank from above and rotate it. During rotation, a tightening mechanism is also provided to tighten the microchannel synchronously. Therefore, when the microchannel passes through the tightening mechanism along the side wall of the inner tank 1, it is squeezed on the side wall of the inner tank 1 and firmly fits with the side wall of the inner tank. Through this device, the assembly efficiency of the microchannel and the inner tank is improved by more than 50%. At the same time, the microchannel and the inner tank are tightly fitted, the product quality is improved, and the energy consumption is reduced (good heat transfer effect).

[0051] The specific operation of this program is as follows:

[0052] Place the liner on the circular cover of the tooling plate and automatically send it to the top of the lifting mechanism. The lifting mechanism automatically lifts the liner and the circular cover on the tooling plate. Click the clamping button, and the upper clamping block presses down to clamp the liner. Long press the rotation button, and the rollers automatically press the microchannel and synchronize the rotation of the liner. Stop when it is in place and press the rotation button. Click the release button, and the rollers, clamping blocks and lifting mechanism will all automatically reset, and the liner will be removed.

[0053] It should be noted here that after the inner liner is compressed, one side of the microchannel needs to be manually hung on several nail holes 100 longitudinally arranged on the inner liner. After the microchannel is rolled and extruded, the two sides of the microchannel are on both sides of the pipe connector 200 of the inner liner, and multiple tension springs are used manually to further pull the two sides to prevent loosening.

[0054] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model.
