Description

Technical Field

[0001] This invention relates to the field of automatic sleeve technology, and in particular to an automatic sleeve device. Background Technology

[0002] Currently, before the coil is packaged, a certain length of insulation pipe is fitted onto the copper pipe connecting the outdoor and indoor units of the air conditioner. Fitting the insulation pipe requires manual insertion of the end of the coiled insulation pipe onto the copper pipe.

[0085] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0086] Reference Figure 1-14 The diagram shows a structural schematic of an embodiment of the automatic sleeve device of the present invention, which may specifically include: a base material conveying device 1, a heat insulation pipe circulation and threading mechanism 3, a docking mechanism 6, and a cutting mechanism 8;

[0087] The base material conveying device 1 includes: an insulated pipe output end and a copper pipe output end;

[0088] The insulation pipe circulation threading mechanism 3 includes a circulation clamping device 56; the circulation clamping device 56 is provided with a reset switching device 57, a circulation clamp and at least two placement layers; the reset switching device 57 is used to switch the position between the placement layers; the placement layers are provided with insulation pipe placement positions;

[0089] A cutting mechanism 8 is provided on one side of the output end of the insulation pipe, and the circulating clamp is used to transfer the insulation pipe cut by the cutting mechanism 8 to the insulation pipe placement position.

[0090] One end of the docking mechanism 6 is aligned with the output end of the copper tube, and the other end is aligned with the placement position of the insulation tube in any placement layer.

[0091] This embodiment will provide a more detailed description of the automatic sleeve device:

[0092] The automatic sleeve device includes a base material conveying device 1, an insulation pipe straightening mechanism 2, an insulation pipe circulating threading mechanism 3, a frame 4, a docking mechanism 6, a conveying mechanism 7, and a cutting mechanism 8;

[0093] The frame 4 is located on the rear side of the base material conveying device 1;

[0094] The upper part of the frame 4 is provided with the insulation pipe straightening mechanism 2;

[0095] The frame 4 is provided with a cutting mechanism 8 and a straightening mechanism 2 on the side near the output end of the insulation pipe of the base material conveying device 1. The output end of the cutting mechanism 8 is adapted to the straightening mechanism 2.

[0096] The insulation pipe circulation threading mechanism 3 is located below the insulation pipe straightening mechanism 2;

[0097] The frame 4 is provided with a docking mechanism 6 on the side near the copper tube output end of the base material conveying device 1. The output end of the docking mechanism 6 is adapted to the heat insulation pipe circulation threading mechanism 3.

[0098] The conveying mechanism 7 is located below the insulation pipe circulation threading mechanism 3. The frame 4 is equipped with an insulation pipe straightening mechanism 2, an insulation pipe circulation threading mechanism 3, a docking mechanism 6, a conveying mechanism 7, and a cutting mechanism 8. The base material conveying device 1 mainly implements the feeding process of insulation pipes and copper pipes. In this embodiment, the insulation pipe is conveyed to the upper part of the frame 4 by the base material conveying device 1, and its output end is aligned with the cutting mechanism 8. After passing through the cutting mechanism, the insulation pipe is gripped by the insulation pipe straightening mechanism 2. After the insulation pipe straightening mechanism 2 pulls the insulation pipe to a preset distance, the insulation pipe is cut by the cutting mechanism 8. The cut insulation pipe is then transferred by the insulation pipe circulation threading mechanism 3 to the docking mechanism 6. It should be clarified that one end of the docking mechanism 6 is aligned with the copper tube output end on the base material conveying device 1, and the other end is adapted and aligned with the position where the insulation pipe circulation threading mechanism 3 grips the insulation pipe. After the insulation pipe to be cut is placed in the aligned position of the docking mechanism 6, the base material conveying device 1 will insert the copper tube into the insulation pipe through the docking mechanism 6. After the sleeve operation is completed, the insulation pipe circulation threading mechanism 3 places the sleeved copper tube onto the bottom conveying mechanism 7. It should be noted that this embodiment also includes an operation panel control box 5, which is connected to the base material conveying device 1, the insulation pipe straightening mechanism 2, the insulation pipe circulation threading mechanism 3, the docking mechanism 6, the conveying mechanism 7, and the cutting mechanism 8 to control their operation.

[0099] In the embodiments of this application, the coordinated operation of multiple workpieces simultaneously, through the coordination of the base material conveying device 1, the insulation pipe straightening mechanism 2, the insulation pipe circulating threading mechanism 3, the docking mechanism 6, the conveying mechanism 7, and the cutting mechanism 8, improves production efficiency. Specifically, the base material conveying device 1 enables automatic feeding of insulation pipes and copper pipes; the coordination between the insulation pipe straightening mechanism 2, the insulation pipe circulating threading mechanism 3, the docking mechanism 6, the conveying mechanism 7, and the cutting mechanism automates the process from insulation pipe cutting and copper pipe fitting to the conveying of the sleeved product. More specifically, in practical applications, the fitting of insulation pipes includes at least three steps: cutting, alignment, and fitting. The automatic sleeve device designed in this application includes: a base material conveying device 1, an insulation pipe circulation and threading mechanism 3, a docking mechanism 6, and a cutting mechanism 8; wherein, the base material conveying device 1 includes an insulation pipe output end and a copper pipe output end. The insulation pipe output from the base material conveying device 1 is first cut in the cutting mechanism 8, and then the circulating clamp of the insulation pipe circulation and threading mechanism 3 transfers the cut insulation pipe to the insulation pipe placement position of the current placement layer (at this time, the cut insulation pipe is the insulation pipe to be threaded). Then, the reset switching device 57 of the insulation pipe circulation and threading mechanism 3 switches the position between the placement layers, so that the insulation pipe placement position of the placement layer with the insulation pipe to be threaded is aligned with one end of the docking mechanism. At this time, the copper pipe output end of the base material conveying device 1 outputs the copper pipe to the other end of the docking mechanism 6, and then the docking mechanism 6 completes the sleeve operation between the copper pipe and the insulation pipe. This application utilizes the fixed position switching of two placement layers in the insulation pipe circulation threading mechanism 3 to achieve accurate alignment of the insulation pipe to be threaded with the copper pipe. Furthermore, while the docking mechanism 6 performs the sleeve operation on one placement layer, the other empty placement layer can connect to the cutting and placement process of the next insulation pipe in parallel, enabling the automatic sleeve device of this application to continuously perform the sleeve operation and improve the working efficiency of insulation pipe sleeve.

[0100] The following will further describe an automatic sleeve device in this exemplary embodiment.

[0101] As an example, the insulation pipe straightening mechanism 2 includes: a straightening guide rail 9, a straightening rack 10, and a straightening assembly 11;

[0102] The straightening rack 10 is movably connected to the frame 4, and the straightening guide rail 9 is connected to the straightening rack 10;

[0103] The straightening assembly 11 is slidably connected to the straightening guide rail 9 via the straightening rack 10.

[0104] As an example, the straightening assembly 11 further includes: a straightening power motor 12, a gripper opening and closing cylinder 13, a telescopic guide rod 14, a linear flange bearing 15, a straightening mechanism mounting plate 16, a telescopic cylinder mounting seat 17, a telescopic cylinder 18, a gripper opening and closing cylinder fixing plate 19, a gripper opening and closing tooling rod 20, a gripper opening and closing connector 21, a gripper 22, a gripper opening and closing guide rod 23, a side plate 24, a toothed guide wheel 25, a straightening slider 26, and a gripper mounting plate 68;

[0105] The straightening mechanism mounting plate 16 has a straightening slider 26 on its side, and the straightening slider 26 is slidably connected to the straightening guide rail 9;

[0106] The straightening power motor 12 is mounted on the straightening mechanism mounting plate 16, and the toothed guide wheel 25 is provided on the output shaft of the straightening power motor 12; the toothed guide wheel 25 is meshed with the straightening rack 10 and is used to drive the straightening assembly 11 to slide along the straightening guide rail 9.

[0107] The telescopic guide rod 14 is connected to the straightening mechanism mounting plate 16 via the linear flange bearing 15, and one end of the telescopic guide rod 14 passes through the straightening mechanism mounting plate 16 and is connected to the gripper mounting plate 68.

[0108] One end of the telescopic cylinder 18 is mounted on the straightening mechanism mounting plate 16 via the telescopic cylinder mounting base 17, and the other end is connected to the gripper mounting plate 68; the telescopic cylinder 18 drives the gripper mounting plate 68 to move up and down along the telescopic guide rod 14;

[0109] The gripper mounting plate 68 has side plates 24 at both ends, and the gripper mounting plate 68 has a gripper opening and closing guide rod 23 on the side away from the straightening mechanism mounting plate 16. The two ends of the gripper opening and closing guide rod 23 are respectively connected to the side plate 24.

[0110] The gripper mounting plate 68 has a gripper opening and closing fixture rod 20 on the side near the straightening mechanism mounting plate 16; one end of the gripper opening and closing fixture rod 20 passes through the gripper mounting plate 68 and is connected to the gripper opening and closing connector 21, and the other end is connected to the gripper opening and closing cylinder fixing plate 19.

[0111] The gripper 22 passes through the gripper opening and closing guide rod 23 and is connected to the gripper opening and closing connector 21. The gripper opening and closing connector 21 drives the gripper 22 to perform a gripping movement.

[0112] The clamping cylinder fixing plate 19 is connected to the clamping cylinder 13. The straightening mechanism mounting plate 16 has a through hole for the clamping cylinder 13 to pass through. The clamping cylinder 13 drives the clamping jaw 22 to perform clamping motion through the clamping tooling rod 20. More specifically, the straightening power motor 12 is used to drive the straightening assembly 11 to slide along the straightening guide rail 9. That is, the toothed guide wheel 25 on the straightening power motor 12 is engaged with the straightening rack 10. When the toothed guide wheel 25 rotates on the straightening rack 10, the straightening assembly 11 will slide along the straightening guide rail 9 on the straightening rack 10. Under the drive of the telescopic cylinder 18, the clamping mounting plate 68 can move up and down, facilitating the gripping and displacement of the insulation pipe. The gripper opening / closing cylinder 13 drives the gripper opening / closing cylinder fixing plate 19 to move up and down, which in turn drives the gripper opening / closing fixture rod 20 to move up and down. Simultaneously, because the gripper opening / closing fixture rod 20 is connected to the gripper opening / closing connector 21, when the gripper opening / closing fixture rod 20 moves upward, the gripper opening / closing connector 21 retracts, causing the gripper 22 to perform a gripping action; when the gripper opening / closing fixture rod 20 moves downward, the gripper opening / closing connector 21 unfolds, causing the gripper 22 to perform a releasing action. It should be noted that in this embodiment, the gripper opening / closing connector 21 consists of two movable arms, with a connection point between the movable arms, around which the movable arms move. The gripper 22 is connected to the end of the movable arm furthest from the connection point, and the gripper 22 also moves through the gripper opening / closing guide rod 23 and is connected to the gripper opening / closing guide rod 23. Therefore, when the jaw opening and closing connector 21 is pressed down, the movable arm on the jaw opening and closing connector 21 will unfold under the cooperation of the connection point and the jaw opening and closing guide rod 23, and the jaw 22 will also unfold at this time; similarly, when the jaw opening and closing connector 21 is lifted up, the movable arm on the jaw opening and closing connector 21 will retract, and the jaw 22 will also retract and clamp.

[0113] As an example, the cutting mechanism 8 includes: a cutting device lifting cylinder fixing seat 27, a cutting device lifting cylinder 28, a cutting device lifting cylinder connecting block 29, a cutting device 30, and a cutting guide rail 36;

[0114] The cutting guide rail 36 is connected to the frame 4, and the cutting guide rail 36 is slidably connected to the cutting device 30;

[0116] The lifting cylinder connecting block 29 of the cutting device is connected to the cutting device 30;

[0117] The output shaft of the lifting cylinder 28 of the cutting device is connected to the cutting device 30 through the lifting cylinder connecting block 29. The lifting cylinder 28 is used to drive the cutting device 30 to slide along the cutting guide rail 36. More specifically, after the insulation pipe is output through the base material conveying device 1, it enters the cutting mechanism. In this embodiment, through the cooperation of the cutting guide rail 36 and the lifting cylinder 28, the cutting device 30 can move up and down along the cutting guide rail 36, which facilitates the subsequent clamping action of the insulation pipe.

[0118] As an example, the cutting device 30 includes: a rear sliding plate with a cutting slider 37, a positioning assembly 31, a first cutting telescopic guide rod 32, a cutting assembly 33, a positioning assembly telescopic cylinder 34, and a positioning assembly telescopic cylinder mounting plate 35;

[0119] One end of the first cutting telescopic guide rod 32 is connected to the positioning component 31, and the other end passes through the cutting component 33 and is connected to the rear sliding plate;

[0120] The cutting assembly 33 is connected to the positioning assembly telescopic cylinder mounting plate 35, and the positioning assembly telescopic cylinder 34 is connected to the cutting assembly 33 through the positioning assembly telescopic cylinder mounting plate 35; the output shaft of the positioning assembly telescopic cylinder 34 is connected to the positioning assembly 31.

[0121] The cutting slider 37 is slidably connected to the cutting guide rail 36.

[0122] As an example, the positioning assembly 31 includes: a pipe-pressing cylinder 38, an upper pressure plate 39, a pin 40, a lower pressure plate 41, and a pipe-pressing cylinder mounting plate 42;

[0123] The lower pressure plate 41 is provided with the pin 40 on the side facing the upper pressure plate 39, and the upper pressure plate 39 is movably connected to the lower pressure plate 41 through the pin 40;

[0124] The pipe-pressing cylinder 38 is mounted on the lower pressure plate 41 via the pipe-pressing cylinder mounting plate 42, and the output shaft of the pipe-pressing cylinder 38 is connected to the upper pressure plate 39. More specifically, the upper pressure plate 39 and the lower pressure plate 41 are provided with recessed areas at corresponding positions. After the upper pressure plate 39 and the lower pressure plate 41 are fitted together, the recessed areas form clamping through holes for holding the insulation pipe. After the insulation pipe is output by the base material conveying device 1, it will first be clamped by this clamping through hole on the positioning component 31. That is, through the operation of the pipe-pressing cylinder mounting plate 42, the upper pressure plate 39 will move along the pin 40 to the lower pressure plate 41, thereby clamping the insulation pipe that passes through.

[0125] As an example, the cutting assembly 33 includes: a cutting assembly mounting plate 43, a guide cylinder 44, a cutting blade 45, a cutting blade connecting block 46, a cutting blade positioning plate 47, a cutting blade mounting plate 48, a second cutting telescopic guide rod 49, a cutting power cylinder connecting plate 50, a cutting power cylinder 51, and a cutting power cylinder connecting rod 52;

[0126] The bottom side of the cutting component mounting plate 43 is provided with a guide rod through hole, and the first cutting telescopic guide rod 32 passes through the guide rod through hole to connect the cutting component 33 between the rear sliding plate and the positioning component 31;

[0127] The bottom center of the cutting component mounting plate 43 is provided with a telescopic cylinder through hole, and the positioning component telescopic cylinder 34 passes through the telescopic cylinder through hole and is connected to the positioning component telescopic cylinder mounting plate 35.

[0128] The bottom of the cutting component mounting plate 43 is provided with the cutting blade mounting plate 48, the cutting blade mounting plate 48 is connected to the cutting blade connecting block 46, and the cutting blade 45 is slidably connected to the cutting blade connecting block 46.

[0129] The guide tube 44 is provided on the cutting assembly mounting plate 43, and the guide tube 44 is close to the cutting area of ​​the cutting blade 45; the bottom of the cutting blade 45 is connected to the cutting blade positioning plate 47.

[0130] One end of the cutting power cylinder connecting rod 52 is connected to the cutting assembly mounting plate 43, and the other end is connected to the cutting power cylinder 51. The output shaft of the cutting power cylinder 51 is connected to the cutting power cylinder connecting plate 50.

[0131] The second cutting telescopic guide rod 49 is connected to the side of the cutting power cylinder connecting plate 50 facing the cutting blade mounting plate 48. One end of the second cutting telescopic guide rod 49 passes through the cutting blade mounting plate 48 and is connected to the cutting blade positioning plate 47.

[0132] The cutting power cylinder 51 drives the cutting blade 45 to perform cutting motion by moving the cutting blade positioning plate 47 up and down. More specifically, to ensure that the insulation tube can enter the guide cylinder 44 more accurately, this embodiment also provides a cutting clamp and a cutting clamp pneumatic device for controlling the clamping action. Both the cutting clamp and the cutting clamp pneumatic device are mounted on the cutting assembly mounting plate 43. The position of the cutting clamp is opposite to the position of the guide cylinder 44, and the channel of the cutting clamp corresponds to the through hole on the guide cylinder 44. The cutting clamp is located on the side close to the positioning assembly 31. That is, after the insulation tube is clamped by the positioning assembly 31, it enters the guide cylinder 44 through the cutting clamp. After the insulation pipe is clamped by the positioning component 31, the cutting component 33, in cooperation with the positioning component telescopic cylinder 34 and the first cutting telescopic guide rod 32, approaches the positioning component 31. At this time, the insulation pipe will be clamped by the cutting fixture. When the cutting fixture clamps the insulation pipe, the positioning component 31 releases the insulation pipe under the action of the pipe pressing cylinder mounting plate 42. At this time, the cutting fixture moves away from the positioning component 31 under the action of the first cutting telescopic guide rod 32 and the positioning component telescopic cylinder mounting plate 35. After the cutting fixture moves away a certain distance, the cutting fixture releases the insulation pipe, and then approaches the positioning component 31 and clamps the insulation pipe again under the action of the first cutting telescopic guide rod 32 and the positioning component telescopic cylinder mounting plate 35. After that, the cutting fixture moves away from the positioning component 31 again under the action of the first cutting telescopic guide rod 32 and the positioning component telescopic cylinder mounting plate 35. These actions are repeated until the end of the insulation pipe is extended to a preset distance, so that the insulation pipe can be clamped by the insulation pipe straightening mechanism 2.

[0133] It should be noted that the cutting blade 45 in this embodiment consists of two movable blades on both sides, and a connection point is provided between the movable blades. This connection point is located in the middle of the movable blades, and the movable blades move around this connection point. The cutting blade positioning plate 47 is connected to the end of the movable blade away from the connection point in the non-cutting section, and the cutting blade positioning plate 47 moves up and down through the cooperation between the cutting power cylinder connecting plate 50 and the second cutting telescopic guide rod 49. Therefore, when the cutting blade positioning plate 47 is pushed up, the movable blade will unfold under the action of the connection point; similarly, when the cutting blade 45 is pulled down, the movable blade will move closer, forming a cutting section. Within this cutting section, the cutting blade 45 can cut the insulation pipe.

[0134] As an example, the insulation pipe circulation threading mechanism 3 further includes:

[0135] Circulating tube-threading motor assembly 53 and tube-threading circulating power unit 58;

[0136] The tube-passing circulation power device 58 is provided with a transmission rod 55, and gears 54 are provided at both ends of the transmission rod 55; the circulating tube-passing motor assembly 53 is connected to the gears 54 and drives the gears 54 to rotate.

[0137] The circulating clamping device 56 is connected to the tube-passing circulating power device 58, and the tube-passing circulating power device 58 drives the circulating clamping device 56 to move. More specifically, the circulating clamping device 56 is inserted into the tube-passing circulating power device 58.

[0138] As an example, the placement layer includes: a placement layer for connecting rods;

[0139] The reset switching device 57 is equipped with a circulating gear 59, a circulating chain 60, a first connecting plate 61, and a circulating sprocket mounting plate 62.

[0140] The circulating sprocket mounting plate 62 is provided with the circulating gear 59 at its left and right ends respectively, and the circulating gear 59 is connected to the circulating chain 60 through transmission.

[0141] The first connecting plate 61 is provided on the circulating chain 60;

[0142] The pipe-through circulation power device 58 is provided with a fixing rod, which is located between the transmission rods 55;

[0143] The circulating gear 59 has a transmission rod through hole in the middle, and the circulating sprocket mounting plate 62 has a fixing rod through hole; the transmission rod 55 and the fixing rod pass through the transmission rod through hole and the fixing rod through hole respectively, and the transmission rod 55 drives the circulating gear 59 to rotate;

[0144] The fixing rod is connected to a heat-insulating pipe clamping bottom assembly;

[0145] The bottom of the insulation pipe clamping bottom assembly is connected to the fixing rod, and the top of the insulation pipe clamping bottom assembly faces the bottom of the circulating clamp;

[0146] The bottom of the circulating clamp is provided with a connecting rod through hole, through which the placing connecting rod passes and is connected to the first connecting plate 61 and the circulating clamp respectively;

[0147] The placement connecting rod is connected to the first connecting plate 61 to form the placement layer. More specifically, the circulating clamp is connected to the placement layer, and the position of the circulating gripper 76 on the circulating clamp is at the insulation pipe placement position; and due to the positional relationship between the cutting mechanism 8 and the docking mechanism 6, there are at least two insulation pipe placement positions on the circulating clamping device 56. Through the rotational relationship between the circulating chain 60 and the first connecting plate 61, the cut insulation pipe is transferred between these two insulation pipe placement positions.

[0148] That is, when the circulating clamp transfers the insulation pipe cut by the cutting mechanism 8 to the insulation pipe placement position...

[0149] As an example, the insulation pipe clamping bottom assembly includes: a dual-axis cylinder 63, a second connecting plate 64, and a gripper opening and closing push rod 65;

[0150] The bottom of the dual-axis cylinder 63 is connected to the fixed rod, and the top of the dual-axis cylinder 63 is connected to the second connecting plate 64.

[0151] The second connecting plate 64 is connected to the gripper opening and closing push rod 65 on the side away from the dual-axis cylinder 63, and the end of the gripper opening and closing push rod 65 away from the second connecting plate 64 is close to the circulating clamp.

[0152] As an example, the circulating clamp includes: a first circulating clamp connecting plate 69, a second circulating clamp connecting plate 70, a circulating clamp connecting side plate 71, a circulating clamp elastic element 72, a circulating clamp connecting rod 73, a circulating clamp horizontal guide rod 74, a circulating clamp opening and closing connector 75, and a circulating gripper 76;

[0153] The gripper opening and closing push rod 65 is located at the bottom of the first circulating clamp connecting plate 69 and is used to push the first circulating clamp connecting plate 69; the circulating clamp connecting rods 73 are respectively connected to both sides of the first circulating clamp connecting plate 69.

[0154] The circulating clamp connecting rod 73 passes through the second circulating clamp connecting plate 70 and is connected to the circulating clamp opening and closing connector 75;

[0155] The second circulating clamp connecting plate 70 is connected to the circulating clamp connecting side plate 71 at its side ends, and the two ends of the circulating clamp horizontal guide rod 74 are connected to the circulating clamp connecting side plate 71 respectively.

[0156] The circulating gripper 76 passes through the circulating clamp horizontal guide rod 74 and is respectively connected to both sides of the circulating clamp opening and closing connector 75;

[0157] The circulating clamp connecting rod 73 is provided with the circulating clamp elastic element 72, and the circulating clamp elastic element 72 is disposed between the first circulating clamp connecting plate 69 and the second circulating clamp connecting plate 70;

[0158] The first circulating clamp connecting plate 69 and the second circulating clamp connecting plate 70 form the connecting rod through hole through the circulating clamp connecting rod 73;

[0159] The placement connecting rod is connected to the second circulating clamp connecting plate 70. More specifically, driven by the circulating tube-threading motor assembly 53 and gear 54, the transmission rod 55 rotates, thereby driving the circulating gear 59 to rotate. When the circulating gear 59 rotates, the circulating chain 60 also rotates, thereby driving the connecting plate 61 to move along the rotation path of the circulating chain 60 on the upper and lower sides of the circulating sprocket mounting plate 62. Since the placement connecting rod is connected to the connecting plate 61, the circulating clamp connected to the placement connecting rod also rotates accordingly. It should be noted that the insulation pipe clamping bottom assembly connected to the fixed rod is not connected to the circulating clamp. The insulation pipe clamping bottom assembly is used to push the first circulating clamp connecting plate 69 on the circulating clamp. That is, when the dual-axis cylinder 63 operates, it will drive the gripper opening and closing push rod 65 to move upward, thereby pushing the first circulating clamp connecting plate 69 to the second circulating clamp connecting plate 70. Since the second circulating clamp connecting plate 70 is fixedly connected to the placement connecting rod, and an elastic element is provided between the second circulating clamp connecting plate 70 and the first circulating clamp connecting plate 69, when the jaw opening and closing push rod 65 moves upward, the first circulating clamp connecting plate 69 will drive the circulating clamp connecting rod 73 to move upward, and then the circulating clamp connecting rod 73 will drive the circulating clamp opening and closing connecting piece 75 to unfold, at which time the circulating jaw 76 opens; when the jaw opening and closing push rod 65 moves downward, the first circulating clamp connecting plate 69 moves downward under the pushing force of the circulating clamp elastic element 72, at which time the circulating clamp connecting rod 73 will drive the circulating clamp opening and closing connecting piece 75 to retract, at which time the circulating jaw 76 clamps. It should be noted that the circulating clamp elastic element 72 in this embodiment is a spring, which is sleeved on the circulating clamp connecting rod 73.

[0160] It should also be noted that the circulating clamp opening and closing connector 75 in this embodiment consists of two movable arms, with a connection point between the movable arms, around which the movable arms move. The circulating gripper 76 is connected to the end of the movable arm away from the connection point, and the circulating gripper 76 also moves through the gripper opening and closing guide rod 23 and is connected to the circulating clamp horizontal guide rod 74. Therefore, when the circulating clamp opening and closing connector 75 is pressed down, the movable arm on the circulating clamp opening and closing connector 75 will unfold under the cooperation of the connection point and the circulating clamp horizontal guide rod 74, and the circulating gripper 76 will also unfold; similarly, when the circulating clamp opening and closing connector 75 is lifted, the movable arm on the circulating clamp opening and closing connector 75 will retract, and the circulating gripper 76 will also retract and clamp.

[0161] As an example, the docking mechanism 6 includes: a docking component mounting plate 66 and a docking component 67;

[0162] The docking component 67 is provided on the docking component mounting plate 66, and the docking component mounting plate 66 is connected to the frame 4;

[0163] The input end of the docking component 67 is adapted and aligned with the copper tube output end of the base material conveying device 1.

[0164] The input and output ends of the docking component 67 are both flared. More specifically, to facilitate the docking and fitting of the copper tube and the cut insulation tube, the frame 4 is also equipped with a docking component 67. The cut insulation tube is moved to the output end of the docking component 67, and the output end of the copper tube of the base material conveying device 1 is aligned with the input end of the docking component 67. To facilitate the input of the copper tube and the docking of the insulation tube, both the input and output ends of the docking component 67 are flared. It should be noted that a copper tube cutting device is also provided at the docking component 67. When the copper tube is fitted into the preset position inside the insulation tube, the copper tube cutting device will cut the copper tube. At this time, the base material conveying device 1 will push the copper tube one end further to ensure that the cut copper tube still inside the docking component 67 can be completely fitted into the insulation tube.

[0165] For ease of understanding, the specific operation process of this embodiment is as follows:

[0166] Before starting the machine, manually pull one end of the insulation pipe on the copper pipe and insulation pipe conveying device through the clamping through hole, shearing fixture and guide tube 44 formed between the upper pressure plate 39 and the lower pressure plate 41 on the positioning component 31, until the end of the insulation pipe is flush with the end of the guide tube 44. After that, turn on the equipment, select the corresponding model program on the operation panel control box 5, and start the equipment after selection.

[0167] After the equipment is started, the pipe-pressing cylinder 38 moves the upper pressure plate 39 to the lower pressure plate 41, pressing down on the insulation pipe. After the action is completed, the positioning component telescopic cylinder 34 moves the cutting component 33 towards the positioning component 31. After it moves into place, the pneumatic device of the shearing clamp on the cutting component 33 closes the shearing clamp to clamp the insulation pipe. After the clamping action is completed, the pipe-pressing cylinder 38 releases the upper pressure plate 39. After the release is completed, the positioning component telescopic cylinder 34 moves the cutting component 33 in the opposite direction relative to the positioning component 31. The purpose of the back-and-forth movement of the cutting component 33 here is to make the end of the insulation pipe extend a certain length relative to the end of the guide cylinder 44, so as to facilitate the gripping of the insulation pipe straightening mechanism 2. After the movement is completed, the pneumatic device of the shearing clamp on the cutting component 33 is activated. After the shearing clamp is opened, the straightening power motor 12 of the insulation pipe straightening mechanism 2 is activated to move the gripper 22 to the guide cylinder 44. After it is moved into place, the gripper opening and closing cylinder 13 is activated to close the gripper 22 and clamp the insulation pipe. After clamping, the straightening power motor 12 is activated again to drive the gripper 22 to move in the opposite direction to the guide cylinder 44, thereby pulling the insulation pipe to the set length and then stopping. The pressing cylinder 38 is activated to move the upper pressing plate 39 to the lower pressing plate 41 and press the insulation pipe again. After pressing the pipe, the telescopic cylinder 18 and the cutting device lifting cylinder 28 are activated at the same time to move the gripper 22 and the cutting device 30 downward, thereby placing the straightened insulation pipe into the multiple circulating clamps on the circulating clamping device 56. The circulating clamps and the gripper 22 are misaligned.After the material is inserted, the dual-axis cylinder 63 closes the circulating clamp on the circulating clamping device 56, clamping the insulation tube. After clamping, the cutting power cylinder 51 extends, thereby driving the second cutting telescopic guide rod 49 to move downward, allowing the cutting blade 45 to cut the insulation tube. After cutting, the cutting power cylinder 51 retracts, resetting the cutting blade 45. After the cutting action is completed, the clamp opening and closing cylinder 13 of the insulation tube straightening mechanism 2 and the cutting mechanism 8 simultaneously actuates to open the clamp 22 of the insulation tube straightening mechanism 2 and the cutting mechanism 8. After opening, the... Simultaneously, the compression cylinder 18 and the lifting cylinder 28 of the cutting device move the gripper 22 and the cutting device 30 upwards. After the insulation pipe straightening mechanism 2 and the cutting mechanism 8 complete the first cycle, they will continue to complete the second cycle of straightening, feeding, and cutting the insulation pipe. Once in position, the circulating pipe threading mechanism's motor drives the gear 54 and the transmission shaft to rotate, thus rotating the circulating clamp above the circulating clamping device 56 to the lower position. At this time, the circulating clamp below that has not yet gripped the insulation pipe will rotate upwards to complete the next cycle. The cyclic clamping action of the insulation pipe, after rotating to the correct position, will align the end of the insulation pipe with the docking end of the docking component 67 of the docking mechanism 6. After docking, the copper pipe and insulation pipe conveying device will push the copper pipe from the device through the hole at the copper pipe docking end of the docking component 67, thus inserting the copper pipe into the insulation pipe. After insertion, the copper pipe cutting device will cut the copper pipe at the copper pipe docking end of the docking component 67. After cutting, the insulation pipe conveying device will convey a further distance of copper pipe, thereby aligning the docking component 67 with the insulation pipe. After the copper tube in section 7 is fully pushed into the insulation pipe and the tube insertion is completed, the dual-shaft cylinder 63 actuates to open the circulating clamp on the circulating clamping device 56, thus placing the copper tube assembly with the insulation pipe inserted onto the conveying mechanism 7. After the material is released, the conveying mechanism 7 transports the copper tube assembly with the sleeve completed to the next process. Then, the power motor of the circulating tube insertion mechanism actuates again, driving the gear 54 and the transmission shaft to rotate, rotating the circulating clamp above the circulating clamping device 56 that has completed the clamping action to the lower position, completing the tube insertion action again, and so on.
