Description

Technical Field

[0001] The invention relates to the field of air conditioning filtration, and in particular to a filter screen winding and pressing device for an air conditioning filter. Background Art

[0002] The air conditioning capillary filter is an important component used to filter impurities in the air conditioning system. Its core function is to effectively filter impurities in the refrigerant through the combined structure of the capillary and the filter to ensure the normal operation of the refrigeration system. The capillary filter is usually composed of capillaries, grids, filter nets and external brass mesh shells. The capillary is used to adjust the flow of the refrigerant, while the filter is responsible for removing tiny impurities to ensure the cleanliness of the refrigerant. The reliability and processing accuracy of the filter directly affect the service life and performance stability of the air conditioning system.

[0003] The preparation process of capillary filters usually includes multiple steps, the main process is as follows:

[0004] First, the flat mesh is wound on the winding rod to form a ring structure. In the traditional winding process, skilled manual operation is required to ensure that the mesh is tightly wound against the winding rod; if mechanical winding is used, a fitting and pressing mechanism needs to be added to keep the mesh in a certain tension during the winding process to prevent it from loosening or dislocation;

[0005] After the mesh is wound, it is moved to the mesh pressing station, where the wound mesh is pressed into the mesh frame by a pressing device to ensure that the mesh fits tightly to the mesh frame.

[0006] After the pressing is completed, the mesh frame with mesh wire needs to be further fixed into the brass mesh shell. This step enhances the overall strength of the filter through the protection of the brass mesh shell, while ensuring that the filter can withstand the high pressure environment in the air conditioning system;

[0007] After the brass lattice shell is fixed, it is necessary to use a positioning device to process positioning holes at specific positions. The precise processing of the positioning holes will help to achieve precise matching of the brass lattice shell with other components in subsequent assembly.

[0008] The above process needs to be divided into multiple processes and multiple processing stations, and there will be very complex mechanical equipment. Therefore, the prior art requires an improved equipment and process flow to simplify the process, improve processing accuracy, and reduce the demand for manpower and equipment. Summary of the invention

[0009] In order to solve the above problems, the present invention provides an air-conditioning filter screen winding and pressing device, which utilizes a brass mesh shell that needs to be processed itself as a limiting wrapping piece when the mesh is wound, thereby simplifying the structure.

[0043] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0044] like Figure 1-Figure 4 As shown, an air conditioner filter screen winding and pressing device of the present invention comprises a bottom plate 2, on which at least three movable support seats 9 are arranged in a surrounding manner. In this embodiment, there are three movable support seats 9, which are arranged in a C shape, and the angles between adjacent movable support seats 9 in the circumferential direction are 90 degrees. A feed trough 4 is also arranged on the base, and the mesh frame 12 enters from the feed trough 4;

[0045] The feed trough 4 is arranged opposite to three surrounding movable support seats 9. A feed push plate 3 can be arranged at the feed inlet of the feed trough 4, and the auxiliary grid 12 is pushed into the screen pressing position. Of course, other feeding methods can also be used, such as Figure 1 and Figure 3 As shown;

[0046] It also includes a gantry bracket 1, which is installed on the bottom plate 2, a fixed guide tube 13 is installed at the middle bottom position of the gantry bracket 1, and a lifting drive mechanism is installed on the gantry bracket 1 corresponding to the top of the fixed guide tube 13;

[0047] It also includes a movable pressing plate 10, which is guided and installed outside the fixed guide tube 13. The movable pressing plate 10 is driven to move up and down by two lifting and pressing mechanisms fixedly installed at the bottom of the gantry bracket 1. The movable pressing plate 10 can be driven to move up and down along the fixed guide tube 13 by the lifting and pressing mechanisms. When the brass mesh shell 15 needs to be taken out, the movable pressing plate 10 is lifted upward. When the brass mesh shell 15 needs to be positioned and pressed, the lifting and pressing mechanisms are pushed out to position and press the brass mesh shell 15.

[0048] like Figure 1-Figure 4 As shown, it also includes a movable rotation positioning mechanism 5, which is movably installed on the movable pressure plate 10, each movable support seat 9 corresponds to a movable rotation positioning mechanism 5, and a positioning space is formed between the movable support seat 9 and the movable rotation positioning mechanism 5 correspondingly arranged at the upper and lower ends, and the brass mesh shell 15 is positioned and installed in the positioning space and is pressed and positioned by the movable pressure plate 10. The movable rotation positioning mechanism 5 is combined with the movable support seat 9, and can move and retreat with the brass mesh shell 15, and can also drive the bottom brass mesh shell 15 to rotate in a circle at a set angle value through the rotation mechanism arranged thereon;

[0049] In order to realize the winding of the mesh wire 6, the present embodiment further includes a winding rod 7, which is movably installed in a telescopic pressure tube 16, and the telescopic pressure tube 16 is movably arranged in the fixed guide tube 13, and the top of the winding rod 7 is connected to the lifting drive mechanism, and the telescopic pressure tube 16 is driven by the lifting drive mechanism to move up and down along the fixed guide tube 13. A winding motor 20 is connected to the top of the winding rod 7, and the winding motor 20 is movably guided and installed in the telescopic pressure tube 16. The mesh wire 6 is flat when not wound, and can be wound into a ring shape and located outside the winding rod 7 after winding. The telescopic pressure tube 16 is pushed out by the lifting drive mechanism, and the telescopic pressure tube 16 can be used to push the mesh wire 6 wound on the winding rod 7 into the mesh frame 12 at the bottom, so that the mesh wire 6 can be pressed in the mesh frame 12;

[0050] In this embodiment, the mesh frame 12 to be pressed is positioned and installed in the middle of the three movable support seats 9, and the top opening of the mesh frame 12 corresponds to the winding rod 7 and the telescopic pressing tube 16. When the telescopic pressing tube 16 pushes out the mesh wire 6 after winding, the mesh wire 6 can be squeezed and positioned in the mesh frame 12 to complete the mesh pressing action;

[0051] During processing, the mesh wire 6 to be wound is wound through the winding rod 7 and is wrapped by at least three brass mesh shells 15 and installed on the outside of the winding rod 7. The three brass mesh shells 15 surround an arc-shaped wrapping cavity, and the mesh wire 6 to be wound is tightly wound on the outside of the winding rod 7. After the winding is completed, the mesh wire 6 is pressed into the grid frame 12 through the telescopic pressing tube 16.

[0052] like Figure 5 and Figure 7 As shown, it also includes a processing positioning mechanism, which is fixedly installed on the base plate 2. When the telescopic pressing tube 16 is pushed downward by the lifting drive mechanism, the telescopic pressing tube 16 presses the mesh wire 6 wound on the winding rod 7 into the grid frame 12, and uses the telescopic pressing tube 16 to push the three brass mesh shells 15 open and move toward the processing positioning mechanism. The processing positioning mechanism is used to process the positioning holes of the movable mesh shell. The mesh pressing action of the telescopic pressing tube 16 can not only realize the mesh pressing, but also realize the extrusion and push of the brass mesh shell 15, so that the brass mesh shell 15 can contact the processing positioning mechanism to complete the processing of the positioning holes.

[0053] Among them, Figure 2As shown, the movable rotation positioning mechanism 5 includes a movable mounting block 51, and the movable mounting block 51 is slidably mounted in a first movable slide groove 53 provided on the movable pressure plate 10, and first guide grooves 21 are provided on both sides of the inner wall of the first movable slide groove 53, and the movable mounting block 51 is movably mounted in the first movable slide groove 53, and first guide sliders are provided at positions corresponding to the first guide grooves 21 on both sides of the movable mounting block 51, and the first guide slider is slidably mounted in the first guide groove 21;

[0054] A motor bracket 54 is fixedly mounted on the top of the movable mounting block 51, and a driving motor 55 is mounted on the motor bracket 54. The motor shaft of the driving motor 55 passes through the movable mounting block 51 and is connected to a first positioning block 56 located at the bottom of the movable mounting block 51. A compression spring 52 is arranged on one side of the movable mounting block 51, and the movable mounting block 51 is pushed out by the compression spring 52 so that the brass mesh shell 15 is always in close contact with the winding rod 7. Since it is always in close contact with the winding rod 7, when the mesh wire 6 is wound, the mesh wire 6 can be well wound on the winding rod 7 to prevent it from loosening.

[0055] A second positioning block 91 is provided on the top of the movable support seat 9, and the upper and lower ends of the brass mesh shell 15 are positioned and installed between the first positioning block 56 and the second positioning block 91. The brass mesh shell 15 is positioned and pressed between the first positioning block 56 and the second positioning block 91 by the movable pressing plate 10 to limit the circumferential rotation of the brass mesh shell 15.

[0056] The first positioning block 56 and the second positioning block 91 are both conical in shape, and can be well pressed and assembled with the brass mesh shell 15. The first positioning block 56 and the second positioning block 91 can both be made of rubber material. A bearing can be added between the second positioning block 91 and the movable support seat 9 to achieve rotational assembly. When it is necessary to perform positioning processing on multiple circumferential surfaces of the brass mesh shell 15, it can be driven by the drive motor 55 to drive the first positioning block 56, the second positioning block 91 and the middle brass mesh shell 15 to rotate in a circle. For example, when positioning processing is required at three positions in the circumferential direction, the brass mesh shell 15 can rotate 120 degrees each time. The drive motor 55 can be a brake motor. When the power is off, the circumferential rotation of the brass mesh shell 15 can be fixed to prevent rotation in the circumferential direction.

[0057] Among them, the lifting and clamping mechanisms include a first driving cylinder 11, the top of the first driving cylinder 11 is fixedly connected to the gantry bracket 1, and the output end of the first driving cylinder 11 is connected to the movable pressing plate 10. When the brass mesh shell 15 is replaced, the movable pressing plate 10 can be lifted by the first driving cylinder 11, so that the first positioning block 56 is separated from the brass mesh shell 15. When the brass mesh shell 15 needs to be positioned, the first driving cylinder 11 is used to push out the movable pressing plate 10, and the first positioning block 56 and the second positioning block 91 are used to position the brass mesh shell 15.

[0058] Among them, the lifting drive mechanism includes a second driving cylinder 14, the output end of the second driving cylinder 14 is connected to the telescopic pressing tube 16, and the telescopic pressing tube 16 is driven by the second driving cylinder 14 to perform up and down lifting actions along the fixed guide tube 13. When it is necessary to press the wound mesh 6, the second driving cylinder 14 is used to push out the telescopic pressing tube 16. At this time, the winding rod 7 is retracted into the telescopic pressing tube 16 until the telescopic pressing tube 16 contacts the upper end surface of the wound mesh 6, and finally the telescopic pressing tube 16 is used to squeeze the mesh 6 into the grid 12.

[0059] In order to facilitate the winding of the unwound mesh 6, a buckling groove 71 can be provided on the winding rod 7, and the bottom of the buckling groove 71 is open. When the mesh 6 is wound, it is buckled into the buckling groove 71 and then wound. When the telescopic pressing tube 16 is pushed out, the mesh 6 is pushed out. The mesh 6 is finally separated from the winding rod 7 from the bottom opening of the buckling groove 71 and falls completely into the grid 12.

[0060] like Figure 7 As shown, in order to realize the rotation and winding of the winding rod 7 driven by the winding motor 20, in this embodiment, a motor slider is installed on one side of the winding motor 20, and a motor limiting slide groove 19 is provided on the inner wall of the telescopic pressing tube 16 along the length direction of the telescopic pressing tube 16. The winding motor 20 is slidably installed in the motor limiting slide groove 19 through the motor slider, and the winding motor 20 can be lifted up and down, but cannot rotate in a circle.

[0061] Among them, Figure 5 and Figure 6 As shown, a pressing portion 17 is formed at the top of the telescopic pressing tube 16, and a contact ball 22 is provided on the pressing portion 17 corresponding to the contact end of each brass mesh shell 15. When the telescopic pressing tube 16 moves from top to bottom, the contact ball 22 contacts the brass mesh shell 15 and squeezes the brass mesh shell 15. The maximum outer diameter of the pressing portion 17 is smaller than the maximum inner diameter of the mesh frame 12, and the mesh wire 6 can be squeezed into the mesh frame 12, as shown in FIG. Figure 5As shown, the brass mesh shell 15 includes a mesh shell main section 151, a mesh shell inclined section 152, and a mesh shell shrinkage section 153. The mesh shell shrinkage section 153 is located at the top when clamped, and is positioned with the first positioning block 56. The mesh shell inclined section 152 is located between the mesh shell main section 151 and the mesh shell shrinkage section 153. When the telescopic pressing tube 16 is pushed out by the cylinder, since the mesh shell main section 151 is always in contact with the winding rod 7 and the mesh wire 6, the pressing part 17 will use the contact ball 22 to contact the mesh shell inclined section 152 first after descending, and use the contact ball 22 to squeeze and push the brass mesh shell 15. The brass mesh shell 15 is pushed out by the inclined guidance of the mesh shell inclined section 152, and then approaches the processing positioning mechanism. The present invention fully utilizes the special structure of the brass mesh shell 15, and can drive the brass mesh shell 15 while completing the mesh pressing, thereby achieving processing positioning during the mesh pressing process, such as Figure 8 As shown by the middle arrow, the brass mesh shell 15 approaches the processing positioning mechanism to complete the positioning processing.

[0062] like Figure 5 and Figure 7 As shown, the processing positioning mechanism includes a U-shaped cover 8, and the U-shaped cover 8 is provided with an extrusion positioning column 18 corresponding to the positioning point position of each brass mesh shell 15. When the brass mesh shell 15 moves toward the U-shaped mesh cover, the brass mesh shell 15 and the extrusion positioning column 18 are squeezed to produce a positioning notch, and the positioning notch is used for the installation of the later filter. Traditionally, a specific positioning mechanism is required for processing and positioning. The present invention utilizes the downward pressing action of the telescopic pressure tube 16 to drive the brass mesh shell 15 to move toward the extrusion positioning column 18, and then completes the extrusion processing of the product after touching. In order to allow the extrusion positioning column 18 to better form a positioning notch on the brass mesh shell 15, in this embodiment, the head of the extrusion positioning column 18 can be conical to increase the pressure and make the positioning notch easier to form.

[0063] Among them, second guide sliders are provided on both sides of the movable support seat 9, a second movable slide groove is provided on the bottom plate 2, second guide grooves are provided on both sides of the inner wall of the second movable slide groove, and the movable support seat 9 is slidably installed in the second guide groove through the second guide slider.

[0064] In order to allow the movable support seat 9 to reciprocate, in this embodiment, the U-shaped cover 8 is provided with a retreat opening groove 81 at a position corresponding to the movable support seat 9. When the telescopic pressure tube 16 is driven downward to squeeze the inclined section 152 of the mesh shell, the brass mesh shell 15 can be pushed to move toward the extrusion positioning column 18, and the movable support seat 9 can move in the second movable slide groove, and the movable mounting block 51 can move in the first movable slide groove 53.

[0065] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope defined in the claims.
