When working, the transverse sliding block 12 can be driven to slide back and forth laterally by rotating the adjusting screw rod 16 through the adjusting hand wheel 17, so as to adjust the distance between the corresponding two groups of guide rollers 14.

[0045] A plurality of guide ring grooves 15 are arranged on the circumferential surface of the guide roller 14 at intervals (see the drawing Figure 5 ); when working, the position of the guide roller 14 can be adjusted through the adjusting hand wheel 17 and the adjusting screw rod 16; in this way, the aluminum tape can pass between the guide ring grooves 15 of the guide roller 14 when working, so that the guide roller 14 can support and guide the aluminum tape through the guide ring grooves 15, thereby achieving the purpose of guiding the aluminum tape to move along the track.

The left lap joint mechanism 33 comprises a left sliding plate 43, an assembly screw rod 39 and a left lap joint block 44 (see the accompanying drawings of the specification Figure 14 and 16 ).

[0054] The positioning plate 27 on one side of the positioning sliding groove 31 is slidably provided with the left sliding plate 43 through a transverse sliding groove 36 (see the accompanying drawings of the specification Figure 15 and 16 ).

In working, the left lap joint block 44 can be moved in the transverse sliding groove 36 by rotating the limiting screw rod 41, so as to control the limit position of the left lap joint block 44.

[0058] The inner side of the left lap joint block 44 is provided with a limiting arc surface 42 (see the accompanying drawings of the specificationFigure 14 When working in this way, the position of the left lap block 44 can be limited by the limiting screw 41, so that the left lap block 44 can extrude the aluminum strip through the limiting arc surface 42 when working, so as to achieve the purpose of deforming the aluminum strip to adhere to the surface of the inner tube 69.

[0059] The hole diameter of the stepped through hole 38 is greater than the diameter of the assembly screw 39, and the purpose of such arrangement is to make the left lap block 44 have a certain buffer space relative to the assembly screw 39, so that the left lap block 44 can deform when subjected to force after overcoming the elastic force of the buffer spring 40, thereby achieving the purpose of making the left lap block 44 always extrude the aluminum strip with a certain elastic force, so that it deforms and adheres to the surface of the inner tube 69 (see the attached drawings of the specification Figure 16 )。

[0063] The hole diameter of the stepped through hole 38 is greater than the diameter of the assembly screw 39, and the purpose of such arrangement is to make the right lap block 37 have a certain buffer space relative to the assembly screw 39, so that the right lap block 37 can deform when subjected to force after overcoming the elastic force of the buffer spring 40, thereby achieving the purpose of making the right lap block 37 always extrude the aluminum strip with a certain elastic force, so that it deforms and adheres to the surface of the inner tube 69 (see the attached drawings of the specification Figure 16 ).

[0064] The left lap mechanism 33 and the right lap mechanism 34 are arranged in a staggered manner (see the attached drawings of the specification Figure 12). The purpose of such an arrangement is to make the right lap joint mechanism 34 act first to press one end of the aluminum strip to adhere to the surface of the inner tube 69, and then the left lap joint mechanism 33 acts to press the other end of the aluminum strip to lap the end of the aluminum strip (see the accompanying drawings Figure 15 ), so as to limit the form of the aluminum strip lap, prevent the problem of high scrap rate caused by uneven lap of the aluminum strip.

[0065] The lap jointer 6 is provided with a former 7 on one side (see the accompanying drawings Figure 2 ); the former 7 includes an assembly frame 45, a pressure joint mechanism 46, and a forming mechanism 47 (see the accompanying drawings Figure 18 ).

[0066] The assembly frame 45 is mounted on the machine table 2; the assembly frame 45 is symmetrically provided with the forming mechanism 47 (see the accompanying drawings Figure 18 and 19 ). The forming mechanism 47 includes a support arm 48, a fine adjustment screw 49, a support vertical rod 52, and a forming groove wheel 53 (see the accompanying drawings Figure 19 and 20 ).

[0068] The other end of the support arm 48 is provided with a mounting sleeve 51 through a stepped hole 50; the side of the mounting sleeve 51 is provided with a positioning counterbore 54 on the circumferential surface (see the accompanying drawings Figure 22 ); one end of the support arm 48 is threadedly connected with a limiting screw 55; the limiting screw 55 is connected with the positioning counterbore 54. The diameter of the stepped hole 50 is larger than the diameter of the mounting sleeve 51, and the positioning counterbore 54 is movably connected with the limiting screw 55; the purpose of such an arrangement of the stepped hole 50 and the limiting screw 55 is to enable the mounting sleeve 51 to move relative to the support arm 48 when it is subjected to force, and to avoid the disconnection between the mounting sleeve 51 and the stepped hole 50.

[0069] The support vertical rod 52 is fixed between the mounting sleeves 51; the forming groove wheel 53 is movably mounted on the support vertical rod 52 through the bearing (see the accompanying drawings Figure 19 and 20The purpose of setting the forming mechanism 47 in this way is to allow the aluminum strip and the inner tube 69 to pass synchronously through the forming mechanism 47 during operation. By rotating the fine-tuning screw 49 to adjust the position of the support arm 48, the position of the forming groove wheel 53 can be adjusted so that it can be squeezed through the arc-shaped groove by rolling and pressing to make it fit against the surface of the inner tube 69.

[0070] A pressing mechanism 46 is mounted on the assembly frame 45 above the molding mechanism 47 (see the instruction manual appendix). Figure 18 The pressing mechanism 46 includes a reference block 56, an adjusting plate 57, a pressure rod 58, and a clamping screw 59 (see the instruction manual appendix). Figure 23 ).

[0071] A reference block 56 is fixedly mounted in the middle of the assembly frame 45; an adjusting plate 57 is fixedly mounted on the reference block 56 by bolts (see the instruction manual appendix). Figure 22 The lower end of the adjusting plate 57 is hinged to a pressure rod 58; a clamping screw 59 is threaded onto the reference block 56 above the pressure rod 58; the lower end of the clamping screw 59 is in contact with the pressure rod 58. During operation, the vertical position of the adjusting plate 57 and the position of the clamping screw 59 can be adjusted by bolts to allow the lower end of the pressure rod 58 to press against the overlapping position of the aluminum strip, thus making the overlap tighter.

[0072] The molding machine 7 is provided with a laminating device A8 and a laminating device B9 on one side (see the instruction manual). Figure 2 );

[0073] Both composite units A8 and B9 include a support 60, an assembly panel 61, and a composite unit 62 (see the attached instruction manual). Figure 25 ).

[0074] A support 60 is fixedly mounted on the machine base 2; an assembly panel 61 is fixedly mounted on one side of the support 60 (see the instruction manual appendix). Figure 24 The assembly panel 61 is provided with a V-shaped clearance through hole 63 (see the instruction manual appendix). Figure 26 During operation, the inner tube 69 passes through the center of the clearance through hole 63.

[0075] Three sets of composite units 62 are arranged in a radiating pattern on the mounting panel 61 on the side of the bypass through hole 63 (see the instruction manual appendix). Figure 25 During operation, the three composite units 62 can extrude the aluminum strip from three directions by rolling and pressing, thus achieving the purpose of pressing and adhering the aluminum strip to the surface of the inner tube 69.

[0076] Composite unit 62 includes composite grooved wheel 67, locking block 66, and locking bolt 65 (see attached instruction manual). Figure 27 and 28) ; two sets of adjusting sliding holes 64 are symmetrically arranged on the assembly panel 61 (see the attached drawing 4 in the description Figure 27 and 28 ) ; locking blocks 66 are fixed on the adjusting sliding holes 64 through locking bolts 65 (see the attached drawing 4 in the description Figure 28 ) ; when the locking bolts 65 are tightened, the locking blocks 66 can be fixed on the assembly panel 61, and when the locking bolts 65 are loosened, the assembly position of the locking blocks 66 can be adjusted along the adjusting sliding holes 64.

[0077] A composite groove wheel 67 is arranged between the locking blocks 66; the arc-shaped slot of the composite groove wheel 67 is consistent with the arc of the circumferential surface of the inner tube 69, so that the composite groove wheel 67 can extrude the aluminum strip along the circumferential surface of the inner tube 69 through the arc-shaped slot, so that the aluminum strip can be kept in close contact with the surface of the inner tube 69.

[0078] Positioning screws 32 are threadedly connected to the assembly panel 61 outside the locking blocks 66; the positioning screws 32 are in abutting connection with the locking blocks 66 (see the attached drawing 4 in the description Figure 27 and 28 ). The purpose of such arrangement is that during assembly, the position of the bottom end of the positioning screw 32 can be adjusted by rotating the positioning screw 32, so as to achieve the purpose of positioning the assembly position of the locking block 66, and further make the slot of the composite groove wheel 67 assembled on the locking block 66 extrude the aluminum strip as much as possible to keep it in close contact with the surface of the inner tube 69. During the movement of the aluminum strip and the inner tube 69, the composite groove wheel 67 can be driven to roll, so that it can extrude the aluminum strip to keep it in close contact with the inner tube 69 during rolling, thereby avoiding the problem that the existing forming die often causes the aluminum strip to be broken due to large frictional resistance when extruding the aluminum strip.

[0079] A heating ring 10 is arranged between the laminator A8 and the laminator B9 (see the attached drawing 4 in the description Figure 2 ). The heating ring 10 is a purchased equipment, which can heat the inner tube 69 and the aluminum strip passing through the inside during work, so that the glue coated on the inner layer of the aluminum strip is melted, so that the aluminum strip is bonded to the surface of the inner tube 69 through the melted glue. The heating temperature can be controlled during the work of the heating ring 10, so that the heating temperature can be controlled within a reasonable range, thereby avoiding the problem of excessively high or low heating temperature.

[0080] The machine table 2 is sequentially provided with an outer plastic tube forming machine 72 and a cooling and shaping water tank B73; the cooling and shaping water tank B73 is sequentially provided with a traction machine 74 and a pipe winding machine 75 (see the attached drawing 4 in the description Figure 1 ). The outer plastic tube forming machine 72, the cooling and shaping water tank B73, the traction machine 74 and the pipe winding machine 75 are all purchased equipments.

[0081] The production device of the aluminum plastic cluster tube, when working, the inner layer plastic tube forming machine 70 first acts to inject and form an inner tube, which is cooled and shaped by the cooling and shaping water tank A71, and then outputted as the inner tube 29. After the inner tube is outputted, it will pass through the guide 3, the pre-variation mold 4, the presser 5, the lapper 6, the former 7, the laminator A8, the heating ring 10 and the laminator B9 in sequence, and then enter the outer layer plastic tube forming machine 72. Then, the outer layer plastic tube forming machine 72 acts to coat an outer tube on the surface of the inner tube 69, which is cooled and shaped by the cooling and shaping water tank B73 and then outputted. Finally, under the traction of the traction machine 74, the pipe winding machine 75 completes the pipe winding work (see the attached drawings of the specification Figure 1 ).

[0082] In the above process, the aluminum strip feeding machine 1 acts synchronously to output the aluminum strip continuously and orderly through the guide 3. In this process, the aluminum strip can pass between the guide ring grooves 15 of the guide rollers 14, so that the guide rollers 14 can support and guide the aluminum strip through the guide ring grooves 15, and then the aluminum strip can move below the inner tube 69 in an unfolded posture.

[0083] Then, when the unfolded aluminum strip output from the guide 3 enters the pre-variation mold 4, the aluminum strip is input between the entering half ring 19 and the arc-shaped bottom plate 18, and then output between the arc-shaped bottom plate 18 and the outputting half ring 20 (see the attached drawings of the specification Figure 6 and 7 ). In this process, the aluminum strip will be gradually bent to a "U" shape under the guidance of the arc-shaped bottom plate 18, and at the same time, the inner tube 69 will be outputted in close contact with the inner surface of the outputting half ring 20. In this way, after the aluminum strip is output from the pre-variation mold 4, it can be output together with the inner tube 69 in a "U" shape.

[0084] When the aluminum strip is output together with the inner tube 69 from the pre-variation mold 4 in a "U" shape and enters the presser 5, the extrusion groove wheel 24 of the presser 5 will extrude and deform the aluminum strip in a rolling extrusion manner from both sides through the arc-shaped slot, so that the aluminum strip is deformed and wrapped on the surface of the inner tube 69.

[0085] When the inner tube 69 and the deformed aluminum strip output from the presser 5 pass through the lapper 6, the inner tube 69 and the aluminum strip will pass through the presser 5 from the positioning sliding groove 31 on the positioning plate 27. In this process, the left lapping block 44 of the right lapping mechanism 34 first extrudes the aluminum strip through the limiting arc surface 42, so as to make the aluminum strip deform and be in close contact with the surface of the inner tube 69 (see the attached drawings of the specification Figure 17 ). Then, the left lapping mechanism 33 acts to extrude the other end of the aluminum strip through the limiting arc surface 42 of the right lapping block 37, so as to lap the other end of the aluminum strip (see the attached drawings of the specification Figure 16 ). In this way, the lapping form of the aluminum strip can be limited, and the problem of high scrap rate caused by uneven lapping of the aluminum strip can be prevented.

[0086] When the inner tube 69 with the overlapped aluminum band is output from the compactor 5 and enters the former 7, the inner tube 69 with the overlapped aluminum band will pass between the forming grooves 47, and in this process, the forming groove wheels 53 will press the aluminum band in a rolling extrusion manner through the arc-shaped slots to make the aluminum band further adhere to the surface of the inner tube 69. In this process, the crimping mechanism 46 can press the overlapped position of the aluminum band through the lower end of the pressing rod 58, so as to make the aluminum band more closely overlapped, and thus the aluminum band forming and wrapping work is completed.

[0087] When the inner tube 69 with the formed and wrapped aluminum band is output from the former 7 and enters the laminator A 8, the laminator A 8 will press the aluminum band through the laminating groove wheel 67 to make the aluminum band adhere to the surface of the inner tube 69. Then the aluminum band will enter the heating ring 10 synchronously with the inner tube 69, and when heated, the glue coated on the inner layer of the aluminum band will be melted, so that the aluminum band is bonded to the surface of the inner tube 69 through the melted glue.

[0088] Then, when the aluminum band and the inner tube 69 are output from the heating ring 10 and enter the laminator B 9, the laminator B 9 will press the aluminum band through the laminating groove wheel 67 to make the aluminum band adhere to the surface of the inner tube 69 and then output.

[0089] After the aluminum band and the inner tube 69 are output and enter the outer plastic tube forming machine 72, the outer plastic tube forming machine 72 acts to coat an outer tube on the surface of the aluminum band 68, and then the aluminum plastic cluster tube is output after being cooled and shaped in the cooling and shaping tank B 73. Finally, the aluminum plastic cluster tube is completed by the winding machine 75 under the traction of the traction machine 74 (see the drawings in the specification). Figure 1 Thus, the aluminum plastic cluster tube production device completes the production of the aluminum plastic cluster tube.

[0090] The aluminum plastic cluster tube production device has compact structure and ingenious design. The overlapper and the former can limit the overlapped form of the aluminum band, and the laminating process of the aluminum band is completed in a rolling extrusion manner, thereby solving the problems of easy breakage of the aluminum band and uneven overlapped aluminum band in the existing cluster tube aluminum band wrapping method, and reducing the waste rate. The device is particularly suitable for the production of aluminum plastic cluster tubes.
