DETAILED DESCRIPTION

[0023] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0024] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0025] Please refer to Figure 1 A winding device for processing porous micro-channel aluminum flat tube, consistent with the prior art device, the device comprises a winding roller 1. Not shown in the figure is that the winding roller 1 is composed of an upper pressing plate and a winding roller located below the pressing plate and fixedly connected thereto, and the outer diameter size of the winding roller is smaller than that of the pressing plate. In actual application, the aluminum flat tube is wound on the outside of the winding roller 1, that is, the aluminum flat tube is wound on the outside of the winding roller, at this time, the height of the aluminum flat tube winding is limited by the pressing plate.

[0026] It must be pointed out that in actual operation, the winding roller should be provided with a corresponding notch or equipped with an automatic winding and unwinding device, which is mainly to adapt to the demand of automation in the production process, to realize the automatic fixing of the end of the winding roller 1 and reduce manual intervention.

[0027] Please refer to Figure 1 and Figure 5 Compared with the prior art device, the present device is particularly provided with an up-down driving mechanism 2, the movable end of the up-down driving mechanism 2 is fixedly connected with the winding roller 1, so that the present device can drive the winding roller 1 to move linearly in the vertical direction through the up-down driving mechanism 2. This design makes the use of the winding roller 1 more flexible. Specifically, in actual operation, when the winding roller 1 is lowered to the same horizontal plane as the aluminum flat tube, the winding roller 1 can be used to wind and roll the aluminum flat tube. After winding is completed, the winding roller 1 can be moved upward to realize separation from the rolled aluminum flat tube. At this time, the cylindrical structure formed by winding the aluminum flat tube can move freely left and right, facilitating subsequent bundling and packaging work.

[0028] It is worth noting that in actual application, the fixed end of the up-down driving mechanism 2 should remain stable in height. Therefore, it can be fixedly connected with the rack shell (not shown in the figure) (such as Figure 1 andFigure 5 As shown, the up-down driving mechanism 2 is fixed to the frame through the bolts on its upper side.

[0029] In addition, it must be pointed out that in actual application, the fixed end of the up-down driving mechanism 2 should also be used in cooperation with the corresponding rotary driving mechanism. This cooperation enables the up-down driving mechanism 2 to drive the winding roller 1 to rotate, so as to realize the winding of the aluminum flat tube during the rotation of the winding roller 1.

[0030] At the same time, as shown in Figure 1 , Figure 2 In order to ensure the stability of the winding process, the lower side of the winding roller 1 is provided with a support plate 6. The upper end of the support plate 6 is in close contact with the winding roller 1, which not only provides support for the aluminum flat tube, but also enables accurate control of the height of the lowermost aluminum flat tube, ensuring that the entire aluminum flat tube winding roll after winding remains flat, facilitating subsequent processing and avoiding damage in actual operation.

[0031] In addition, the upper end of the support plate 6 is designed to be rotatably connected to the corresponding rotary disc (as shown in Figure 2 , a disc-shaped structure located in the middle of the upper side of the support plate 6) to cooperate with the corresponding rotary driving mechanism, thereby minimizing the resistance during the rotation of the winding roller 1.

[0032] In actual operation, once the winding work is completed, the up-down driving mechanism 2 moves the winding roller 1 upward to separate it from the aluminum flat tube. At this time, in order to control the movement of the aluminum flat tube winding roll to the right for subsequent bundling and packaging processes, the device is equipped with left-right driving mechanisms 7 on the left and right sides of the support plate 6. The active end of these driving mechanisms is fixedly connected to the support plate 6, and in this way, the left-right driving mechanisms 7 can drive the support plate 6 to realize the left-right linear motion of the aluminum flat tube winding roll.

[0033] As shown in Figure 2 , the left-right driving mechanisms 7 include corresponding lead screws and internal threaded holes below the support plate 6 that cooperate with the lead screws. Through the cooperation of the two lead screws arranged in front and back, the left-right linear motion of the support plate 6 can be realized during synchronous rotation.

[0034] In actual application, the axial end of the lead screw should also be equipped with a corresponding driving motor or transmission mechanism to realize the rotation of the lead screw through the driving motor or transmission mechanism.

[0035] Further, to ensure that the aluminum flat tube winding roll and the support plate 6 remain stable connection during the left and right linear motion of the aluminum flat tube winding roll, and the position of the aluminum flat tube winding roll always meets the predetermined requirements, the device is configured with front and rear driving mechanisms 5 on the upper side of the support plate 6. The fixed end of these driving mechanisms is fixedly connected with the support plate 6, and the movable end is respectively provided with a limiting mechanism 4. Through the direct contact between the limiting mechanism 4 and the aluminum flat tube winding on the outer side of the winding roller 1, it is ensured that the aluminum flat tube remains in the predetermined position during winding, avoiding deviation. At the same time, the front and rear driving mechanisms 5 ensure that the limiting mechanism 4 and the aluminum flat tube winding roll do not have position conflicts during the winding process of the aluminum flat tube. After winding is completed, the limiting mechanism 4 can apply appropriate fastening effect to the aluminum flat tube winding roll, ensuring the integrity of the limiting effect.

[0036] As shown in Figure 1 , Figure 2 The corresponding front and rear driving mechanisms 5 include a cylinder device, wherein the fixed end of the cylinder is fixedly connected with the support plate 6, and the movable end of the cylinder is fixedly connected with the limiting mechanism 4.

[0037] Specifically, as shown in Figure 2 , Figure 3 The limiting mechanism 4 includes a top rod 405, and the top rod 405 is fixedly connected with a contact member 11 near one end close to the winding roller 1. The contact member 11 directly abuts against the aluminum flat tube winding on the outer side of the winding roller 1.

[0038] In practice, to ensure that there is enough pressure between the contact member 11 and the winding roller 1, and to ensure that there is no stroke conflict between the top rod 405 and the movable end of the front and rear driving mechanisms 5, the device is provided with a compression spring I outside the end of the top rod 405 away from the winding roller 1. One axial end of the compression spring I abuts against the top rod 405, and the other axial end of the compression spring I abuts against the movable end of the driving mechanism. This makes the top rod 405 and the movable end of the front and rear driving mechanisms 5 movably connected, and the necessary elastic force is provided by the compression spring I to ensure the stability of the aluminum flat tube during winding.

[0039] Further, the limiting mechanism 4 includes a slide rail I 10 stably connected with the movable end of the driving mechanism, and the inner side of the slide rail I 10 is provided with a positioning rod 401 which can slide linearly in the left and right directions.

[0040] The limiting mechanism 4 also comprises a constraint rod 403, one end of which is fixedly connected with the contact member 11 near the winding roller 1, and the other end is rotatably connected with a driven rod 404 through a pivot I 402 away from the winding roller 1. The driven rod 404 is also rotatably connected with a top rod 405, and the pivot I 402 is rotatably connected with the positioning rod 401. The position of the pivot I 402 is constrained by the positioning rod 401, so that when the corresponding contact member 11 of the top rod 405 contacts the aluminum flat tube winding roll, the movable end of the front and rear driving mechanism 5 continues to move towards the aluminum flat tube winding roll, and the compression spring I is compressed under stress. At this time, the constraint rod 403 can synchronously shorten the distance between itself and the aluminum flat tube winding roll, and the angle of the constraint rod 403 is used to realize accurate limiting of the aluminum flat tube winding roll, so that the aluminum flat tube winding roll cannot move linearly in the left and right directions on the support plate 6 under the cooperative action of the constraint rod 403.

[0041] In addition, in order to ensure that the aluminum flat tube can be actively disconnected from the subsequent aluminum flat tube after winding to form an independent aluminum flat tube winding roll, the device is provided with a shearing mechanism 3 on one side of the support plate 6. The shearing mechanism 3 is located in the same vertical plane as the aluminum flat tube that is not wound outside the winding roller 1, so as to realize accurate shearing of the aluminum flat tube.

[0042] In detail, the shearing mechanism 3 is composed of two shearing blocks 301 arranged symmetrically front and back, as shown in Figure 5 When the two shearing blocks 301 move relative to each other to be in the same vertical plane, they can cooperate to complete the cutting of the aluminum flat tube.

[0043] The distal end of each shearing block 301 is fixedly connected with a follower rod 302; a slide rail II 8 is mounted on the outer side of each follower rod 302, so that the follower rod 302 can move linearly in the slide rail II 8. In addition, the lower ends of the two slide rails II 8 are fixedly connected with a positioning member I 9.

[0044] It is worth noting that the positioning member I 9 is fixed to the rack through bolts arranged below, ensuring the stability of its position in actual operation.

[0045] The distal end of each follower rod 302 is provided with a connecting rod member, which is composed of two hinged drive rods 303. One end of the connecting rod member is rotatably connected with the corresponding follower rod 302, and the other end is rotatably connected with a pivot II 306.

[0046] In addition, the shearing mechanism 3 also comprises two positioning members II 305 arranged front and back, and the distal end of each positioning member II 305 is rotatably connected with the pivot II 306. In actual application, the positioning member II 305 is also fixed to the rack through bolts arranged below, ensuring the stability of its position.

[0047] In this design, by the position restriction of the positioning member Ⅱ 305 on the pivot Ⅱ 306 and the trajectory restriction of the slide rail Ⅱ 8 on the movement of the follower rod 302, the device can adjust the relative distance between the two shearing blocks 301 while the angle of the connecting rod member changes.

[0048] Further, in order to control the angle of the connecting rod member, the device is fixedly connected with a left-right axial compression spring Ⅱ 304 near one end of the connecting rod member, and the other end of the compression spring Ⅱ 304 is in contact with the connecting rod member. The end of the connecting rod member away from the compression spring Ⅱ 304 is in contact with the positioning rod 401. Therefore, when the compression spring Ⅰ is compressed under force, the distance between the constraint rod 403 and the winding roll of the aluminum flat tube is shortened synchronously, and the two shearing blocks 301 can also shorten the distance synchronously to realize the cutting of the aluminum flat tube. At this time, the compression spring Ⅱ 304 is compressed under force, and when the elastic potential energy accumulated by the compression spring Ⅰ is released, the pressing force of the positioning rod 401 on the connecting rod member is also released, and the compression spring Ⅱ 304 synchronously releases its elastic potential energy.

[0049] Specifically, as shown in Figure 3 When the compression spring Ⅰ and the compression spring Ⅱ 304 are not under force, the included angle of the two drive rods 303 away from the positioning rod 401 is less than 180°. This design makes the included angle of the two drive rods 303 away from the positioning rod 401 increase when the positioning rod 401 moves towards the positioning member Ⅱ 305.

[0050] At the same time, the device stipulates that when the compression spring Ⅰ and the compression spring Ⅱ 304 are not under force, the included angle of the two drive rods 303 away from the positioning rod 401 is less than 180°. In combination with the characteristics that the compression spring Ⅰ and the compression spring Ⅱ 304 are compressed under force during the movement of the front and rear drive mechanisms 5 towards the winding roll of the aluminum flat tube, the movement rate of the two shearing blocks 301 can be gradually reduced, thereby increasing the shearing force and ensuring that the shearing blocks 301 can effectively cut off the aluminum flat tube.

[0051] Specifically, the contact member 11 is composed of a mounting frame 1101 fixedly connected with the top rod 405 and the constraint rod 403. One end of the mounting frame 1101 is close to the winding roller 1 and is connected with a plurality of contact wheels 1102 arranged in an upper and lower axial direction through a rotary connection device. The contact wheels 1102 are equidistantly distributed, which ensures that the contact wheels 1102 can be in direct contact with the aluminum flat tube winding roll in actual operation. By utilizing the inherent characteristics of the contact wheels 1102, it can be ensured that the contact member 11 corresponding to the constraint rod 403 can maintain the close contact between the contact wheels 1102 and the aluminum flat tube winding roll, thereby avoiding the collision between the mounting frame 1101 and the aluminum flat tube in the stroke. In addition, the rotary connection design of the contact wheels 1102 and the mounting frame 1101 enables the contact wheels 1102 to push the edge aluminum flat tube flat when the aluminum flat tube winding roll continues to rotate after being cut off by the shearing mechanism 3 in actual application, thereby ensuring that the side end of the aluminum flat tube winding roll is flat without protrusion and guaranteeing the uniformity of the aluminum flat tube in the winding process.

[0052] In the actual application process of the utility model,

[0053] Firstly, the operator controls the up and down driving mechanism 2 to ensure that the movable end of the up and down driving mechanism 2 moves downward to the position in contact with the supporting plate 6:

[0054] Then, the operator starts the equipment, and the aluminum flat tube continuously moves from left to right. When the aluminum flat tube contacts the winding roller 1, the end of the aluminum flat tube is embedded into the notch on the winding roller or cooperates with the automatic winding and unwinding device on the winding roller;

[0055] Subsequently, the operator starts the corresponding rotary driving mechanism, and the winding roller 1 starts to rotate. The aluminum flat tube continuously winds outside the winding roller 1;

[0056] After that, when the diameter of the aluminum flat tube winding roll outside the winding roller 1 reaches the expected value, the operator starts the corresponding front and rear driving mechanism 5. The contact member 11 corresponding to the top rod 405 contacts the aluminum flat tube winding roll, and at the same time, as the movable end of the front and rear driving mechanism 5 continuously moves, the compression spring I and the compression spring II 304 are compressed under stress. The contact member 11 corresponding to the constraint rod 403 contacts the aluminum flat tube winding roll, and the two shearing blocks 301 move towards each other until the right side aluminum flat tube is cut off;

[0057] Then, the rotary driving mechanism continues to operate, and the aluminum flat tube adjacent to the aluminum flat tube winding roll but not wound contacts the contact wheel 1102. The aluminum flat tube winding roll forms a whole without protrusion at the side end;

[0058] Finally, the operator starts the left and right driving mechanism 7, and the supporting plate 6 drives the aluminum flat tube winding roll to move rightward to complete bundling and winding in cooperation with the limiting mechanism 4. In this process, the positioning rod 401 is separated from the connecting rod member, and the two shearing blocks 301 move away from each other.

[0059] While the embodiments of the present application have been illustrated and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the spirit and scope of the application, which is defined by the appended claims and their equivalents.
