[0039] refer to Figure 1 and Figure 2An auxiliary shell 21 is sleeved on the connecting tube 2, and the auxiliary shell 21 is fixedly connected to the connecting tube 2. The end of the auxiliary shell 21 away from the body 1 is open, and the end of the auxiliary shell 21 away from the body 1 is provided with a first sleeve 3. The connecting tube 2 and the first sleeve 3 are plugged and adapted, and the first sleeve 3 and the auxiliary shell 21 are plugged and adapted.

The auxiliary shell 21 is provided with a clamping component 4 for clamping and fixing with the first sleeve 3 at the first movable groove 211.

[0040] The card assembly 4 includes a card block 41 and a slide rod 42. The card block 41 is arranged in the first movable groove 211. The card block 41 and the card groove 32 are card-fitted. The slide rod 42 and the card block 41 are fixedly connected on the side of the bottom wall of the first movable groove 211. The end of the slide rod 42 away from the card block 41 passes through the auxiliary shell 21 and is slidably connected to the auxiliary shell 21. The side of the card block 41 away from the slide rod 42 is set as an inclined surface. A pull plate 22 is fixedly provided on the end of the slide rod 42 away from the card block 41.

[0041] When the first sleeve 3 is connected to the connecting tube 2, the first sleeve 3 is moved toward the body 1, and one end of the first sleeve 3 is sleeved outside the connecting tube 2. As the first sleeve 3 moves, the end of the first sleeve 3 gradually enters the auxiliary shell 21. During the movement of the end of the first sleeve 3 in the auxiliary shell 21, the end of the first sleeve 3 first contacts the inclined surface of the block 41 and pushes the block 41 toward the first moving groove 211. The block 41 drives the slide bar 42 to move, and the slide bar 42 drives the pull plate 22 to move. A spring 23 is stretched, and after the end of the first sleeve 3 and the inner wall of the auxiliary shell 21 facing the side wall of the body 1 are abutted, the block 41 and the slot 32 are aligned, and the first spring 23 contracts and drives the pull plate 22 to move toward the auxiliary shell 21, the pull plate 22 drives the slide bar 42 to move, and the slide bar 42 drives the block 41 to move, and one end of the block 41 is snapped into the slot 32, thereby realizing the snap-fit ​​fixation of the connecting tube 2 and the first sleeve 3, and at the same time, the raw material in the connecting tube 2 can enter the first sleeve 3.

[0042] refer to Figure 1 , Figure 3 and Figure 4A first extrusion shell 31 is fixedly disposed at one end of the first sleeve 3 away from the auxiliary shell 21, the first extrusion shell 31 and the first sleeve 3 are connected at the connection, an extrusion hole 311 is penetrated through one side wall of the first extrusion shell 31, a second extrusion shell 5 is disposed outside the first extrusion shell 31, the second extrusion shell 5 is rotatably connected to the first extrusion shell 31, a plurality of guide holes 51 are disposed on the inner wall of the second extrusion shell 5, the other end of the guide hole 51 penetrates through one side wall of the second extrusion shell 5 away from the machine body 1, and the second extrusion shell 5 is away from the side wall of the machine body 1. A plurality of extrusion tubes 52 are fixedly provided, and the plurality of extrusion tubes 52 correspond to and are connected with the plurality of guide holes 51 one by one, and the inner diameters of the plurality of extrusion tubes 52 are all different. A second sleeve 33 is fixedly provided on the side of the second extrusion shell 5 facing the body 1, and the second sleeve 33 is sleeved outside the first sleeve 3, and the second sleeve 33 is rotatably connected to the first sleeve 3. A support plate 13 is fixedly provided on the side of the body 1 facing the connecting tube 2, and an electric cylinder 14 is fixedly provided on the support plate 13, and a rotating component 6 capable of driving the second sleeve 33 to rotate is provided at the electric cylinder 14.

[0043] The rotating assembly 6 includes a rack 62 and a gear 61. One end of the rack 62 is fixedly connected to the output shaft of the electric cylinder 14. The gear 61 is arranged on the second sleeve 33. The second sleeve 33 passes through the gear 61. The second sleeve 33 and the gear 61 are fixedly connected. The rack 62 and the gear 61 are meshed and matched.

[0044] The raw material enters the first sleeve 3 and is then introduced into the first extrusion shell 31. Inside the first extrusion shell 31, the raw material flows into the guide hole 51 aligned with it through the specific extrusion hole 311, and then smoothly transfers to the extrusion tube 52. Finally, after this series of processes, the raw material is extruded in the extrusion tube 52 to form a sealing strip that meets the set specifications. When it is necessary to produce sealing strips of different specifications, the electric cylinder 14 is started, and the electric cylinder 14 drives the rack 62 to move. The rack 62 meshes with the gear 61, thereby driving the gear 61 to rotate. The rotation of the gear 61 causes the second sleeve 33 to rotate accordingly, and the second sleeve 33 drives the second extrusion shell 5 to rotate, and finally the movement of the second extrusion shell 5 causes the extrusion tube 52 to move. When the guide hole 51 connected to the extrusion tube 52 corresponding to the required specifications is aligned with the extrusion hole 311, the rack 62 stops moving, so that the raw material in the first extrusion shell 31 can be extruded from the extrusion tube 52 of the selected specifications.

[0045] refer to Figure 1 , Figure 3 and Figure 4A fixing block 24 is fixedly provided on the upper surface of the auxiliary shell 21, and the length direction of the fixing block 24 is parallel to the length direction of the connecting tube 2. A second movable groove 241 is provided on the side of the fixing block 24 away from the body 1 along its own length direction. The fixing block 24 is slidably connected with a positioning rod 242 at the second movable groove 241, and a second spring 243 is fixedly provided between the positioning rod 242 and the inner bottom wall of the second movable groove 241. The extension direction of the second spring 243 is parallel to the moving direction of the positioning rod 242.

A plurality of positioning holes 331 are provided on the side of the second sleeve 33 facing the fixing block 24, and the positioning holes 331 correspond to the extrusion tube 52 one by one.

[0046] When the extrusion hole 311 is aligned with the guide hole 51, the end of the positioning rod 242 away from the second spring 243 will extend into the corresponding positioning hole 331. In order to produce sealing strips of different specifications, the second sleeve 33 rotates, and the positioning rod 242 will move into the second movable groove 241 under the guidance of the side wall of the positioning hole 331, and the second spring 243 will be compressed. Once the positioning hole 331 corresponding to the extrusion tube 52 of the required specifications is aligned with the positioning rod 242, the second spring 243 will release its stored elastic force, push one end of the positioning rod 242 into the positioning hole 331, lock the movement of the rack 62, and the extrusion tube 52 of the required specifications is smoothly connected with the extrusion hole 311. The design of the positioning rod 242 and the positioning hole 331 simplifies the control process of the rotation angle of the second extrusion shell 5 by the staff, and also promotes the rapid alignment of the guide hole 51 and the extrusion hole 311.

[0047] refer to Figure 1 , Figure 2 and Figure 3 Two positioning plates 34 are fixedly provided on one side wall of the first sleeve 3 . The two positioning plates 34 are parallel to each other. The positioning rod 242 is located between the two positioning plates 34 . The two side walls of the positioning rod 242 are respectively in contact with the two positioning plates 34 .

[0048] When connecting the first sleeve 3 and the connecting pipe 2, the positioning rod 242 is first placed between the two positioning plates 34. Then, the first sleeve 3 is moved until its end is tightly fitted to the inner wall of the auxiliary shell 21 close to the body 1. In this process, the combination of the positioning rod 242 and the positioning plate 34 creates conditions for the smooth alignment of the clamping block 41 and the clamping groove 32. The positioning rod 242 also constrains the positioning plate 34, so that the first sleeve 3 is not easy to rotate when the second sleeve 33 rotates, thereby improving the stability and accuracy of the operation.

[0049] refer to Figure 1 , Figure 3 and Figure 4A plug-in tube 53 is slidably connected to the guide hole 51 of the second extrusion shell 5.

[0050] The moving assembly 7 includes a slider 71 and a third spring 72. The slider 71 is arranged in the slide groove 54. The slider 71 is slidably connected to the second extrusion shell 5. The slider 71 is fixedly connected to the plug tube 53 on one side facing the guide hole 51. The third spring 72 is fixedly arranged between the slider 71 and a side wall of the slide groove 54. The extension direction of the third spring 72 is parallel to the length direction of the plug tube 53.

[0051] When the guide hole 51 and the extrusion hole 311 are aligned, one end of the plug-in tube 53 is plugged into the extrusion hole 311, and the raw material enters the plug-in tube 53 from the extrusion hole 311, and then enters the guide hole 51 from the plug-in tube 53, so that the raw material is not easily squeezed into the gap between the first extrusion shell 31 and the second extrusion shell 5. When replacing the extrusion tube 52 of different specifications, the second extrusion shell 5 drives the plug-in tube 53 to move, and the plug-in tube 53 with one end in the extrusion hole 311 moves toward the guide hole 51 under the guidance of the side wall of the extrusion hole 311. The plug-in tube 53 drives the slider 71 to move, and the third spring 72 is compressed. At the same time, after the extrusion tube 52 of the required specifications is connected to the extrusion hole 311, the third spring 72 releases its elastic force to push the slider 71 to move, and the slider 71 drives the plug-in tube 53 to move, so that one end of the plug-in tube 53 is plugged into the extrusion hole 311.

The end of the first connecting rod 81 close to the body 1 is rotatably connected to the roller 59. The end of the first connecting rod 81 away from the roller 59 is fixed with an auxiliary plate 57. The auxiliary plate 57 and the first connecting rod 81 are perpendicular. The fourth spring 82 is fixed between the auxiliary plate 57 and the second extrusion shell 5. The fourth spring 82 is sleeved outside the first connecting rod 81. The lower surface of the auxiliary plate 57 is hinged with the second connecting rod 58. The end of the second connecting rod 58 away from the auxiliary plate 57 is hinged to the end of the sealing plate 56 away from the connecting plate 55. A support rod 9 is fixed on the side of the body 1 facing the second extrusion shell 5. The end of the support rod 9 away from the body 1 is fixedly connected to a guide plate 91. The guide plate 91 is arc-shaped, and the opposite sides of the guide plate 91 are set as inclined surfaces.

[0054] During the rotation of the second extrusion shell 5, the second extrusion shell 5 drives the connecting plate 55 and the first connecting rod 81 to move synchronously, and the connecting plate 55 then pushes the sealing plate 56 to move, while the first connecting rod 81 pulls the auxiliary plate 57 and the roller 59 to move. As the roller 59 moves, it gradually contacts the inclined surface of the guide plate 91, and moves toward the second extrusion shell 5 under the guidance of the inclined surface. This movement, through the chain reaction of the roller 59, the first connecting rod 81, and the second connecting rod 58, eventually prompts the sealing plate 56 to complete the flipping action, thereby releasing the blockage of the end of the extrusion tube 52. At the same time, for the extrusion tube 52 that is not connected to the extrusion hole 311, the corresponding sealing plate 56 maintains the blocking state of its end.

[0055] The implementation principle of the energy-saving sealing strip extrusion molding equipment of the embodiment of the present application is as follows: the raw material enters from the feed port 11 on the machine body 1, flows to the discharge port 12 after mechanical extrusion in the machine body 1, passes through the connecting pipe 2 and enters the first sleeve 3, then flows into the first extrusion shell 31, and then enters the guide hole 51 in the second extrusion shell 5 through the extrusion hole 311 on the side wall. Finally, the raw material is extruded and molded from the extrusion tube 52 connected to the guide hole 51. When sealing strips of different specifications need to be produced, the rotating component 6 is started to drive the second extrusion shell 5 to rotate, thereby driving the extrusion tube 52 of the required specifications to move to the set position. At this time, the extrusion tube 52 is connected to the extrusion hole 311 to continue the production operation. The entire process does not require manual replacement of the extrusion mold, which saves time and improves the production efficiency of the sealing strip.

[0056] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
