Description

Technical Field

[0001] The invention belongs to the technical field of heat drying equipment, in particular to a double-wound single-through heat shrink tube heating and drying integrated device. Background Art

[0002] In wire processing and production equipment, the use of heat shrink tubing is very common. It can provide good insulation protection while enhancing the mechanical strength and environmental resistance of the wire.

[0003] When heat shrink tubing is used to combine wires, it is usually necessary to put the heat shrink tubing on the wire to be processed, and then use heating equipment to shrink the heat shrink tubing evenly and fit tightly to the surface of the wire. During assembly line operation, the combination of heat shrink tubing and wires is mostly done manually or in a baking channel. During manual operation, workers are required to manually combine the heat shrink tubing with the wires, and then use heating equipment such as a hot air gun to heat-bake the heat shrink tubing. During the operation, not only is the degree of automation low and the labor intensity of workers high, but there are also safety hazards such as burns. When using a baking channel for heating, transportation equipment is required to transport the combined heat shrink tubing and wires to the oven. On the one hand, the heating not only acts on the heat shrink tubing, but also on the wires, which can easily have a negative impact on the wires themselves. On the other hand, the oven is too open and the heating area is too large, resulting in low heating efficiency and excessive heating energy consumption, which is not in line with the production concept of energy conservation and emission reduction.

DETAILED DESCRIPTION

[0040] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0041] like Figures 1 to 9As shown, the double-punch single-thread heat shrink tube heating integrated device of the present invention comprises a workbench 1 and a fixed-point heating mechanism installed on the workbench 1;

[0042] The fixed-point heating mechanism is used to heat the heat shrinkable sleeve at a fixed point, and the fixed-point heating mechanism includes a bite plate 2, a circulation pump 22 and an electric heater 25;

[0043] The bite disks 2 are symmetrically mounted on the workbench 1. The circumferential surfaces of the bite disks 2 are provided with heating grooves 21, and the heating grooves 21 on the two bite disks 2 correspond to each other. The bite disks 2 are made of heat-resistant material.

[0044] The occlusal disc 2 is provided with ventilation slots 23, and the ventilation slots 23 correspond to the heating slots 21 one by one;

[0045] The bite disk 2 is rotatably mounted with a distribution pipe 24, which is coaxial with the bite disk 2. The opening of the distribution pipe 24 is arranged corresponding to the ventilation slots 23. During the rotation of the bite disk 2, the ventilation slots 23 are connected to the opening of the distribution pipe 24 one by one.

[0046] The circulation pump 22 is installed on the workbench 1, and the distribution pipe 24 is connected to the output end and the output end of the circulation pump 22 respectively, and an electric heater 25 is installed in the distribution pipe 24 connected to the output end of the circulation pump 22, and the electric heater 25 is used to heat the airflow.

[0047] When combining the heat shrink tubing with the wire, since the heat shrink tubing is mostly only located at the end of the wire, a fixed-point heating mechanism is provided in the present invention. By performing fixed-point heating on the assembled wire and the heat shrink tubing, while ensuring the heating effect, it can not only avoid irrelevant parts from being heated, but also enhance the energy-saving effect of the equipment, which is in line with the production concept of energy conservation and emission reduction.

[0048] Specifically, when heating and shrinking the wire and the heat shrink tubing, in order to achieve fixed-point heating of the wire and the heat shrink tubing, in actual use, the heat shrink tubing is first sleeved on the wire, and then the combined wire and the heat shrink tubing are placed between the two bite disks 2. During the rotation of the bite disks 2, the wire and the heat shrink tubing move to the gap between the two bite disks 2, and by controlling the position of the wire and the heat shrink tubing entering the gap between the bite disks 2, the wire and the heat shrink tubing can be moved to the heating groove 21 at the position to be heated. After the equipment is started, the circulation pump 22 fixed on the workbench 1 continuously extracts air from the input end and pumps it to the output end. Since the output end and the output end of the circulation pump 22 are directly connected to the distribution pipe 24, and the two distribution pipes 24 are located in the two bite plates 2, the distribution pipe 24 connected to the input end of the circulation pump 22 is negatively pressurized, while the distribution pipe 24 connected to the output end of the circulation pump 22 is positively pressurized. In this embodiment, the distribution pipe 24 connected to the output end of the circulation pump 22 is located on the upper The upper bite plate 2 is located in the upper bite plate 2, and the distribution pipe 24 connected to the input end of the circulation pump 22 is located in the lower bite plate 2. Because the distribution pipe 24 connected to the output end of the circulation pump 22 is installed with an electric heater 25, the electric heater 25 heats the air after it is started, so that the high-temperature airflow gushes out of the upper distribution pipe 24, and the distribution pipe 24 rotates relative to the bite plate 2 during the rotation process, so that the distribution pipe 24 is only connected to one of the ventilation slots 23 at the same time, and because the two distribution pipes 24 The openings are opposite to each other, so the corresponding ventilation grooves 23 and heating grooves 21 on the two bite disks 2 are connected. At this time, the hot air flow flows from the ventilation grooves 23 in the upper bite disk 2 into the heating grooves 21, heats the wires and heat shrink tubing clamped by the upper and lower heating grooves 21, and then flows into the heating grooves 21 and ventilation grooves 23 opened on the lower bite disk 2, and finally is extracted by the circulation pump 22 and input into the distribution pipe 24 above again. During this process, the bite disk 2 continues to rotate, and then continues the heating operation.

[0049] The present invention sets a fixed-point heating mechanism. When heating the wire and the heat shrink tubing, on the one hand, the heated part is covered and isolated, thereby preventing the hot air flow from heating the part that does not need to be heated, thereby reducing the probability of high temperature damage to the wire while reducing the heating space and reducing heating energy consumption. On the other hand, through the rotation of the bite plate 2 and the switching of the heating groove 21 and the ventilation groove 23, the dynamic closure of the heated part of the wire and the heat shrink tubing is achieved, which can not only reduce the interaction between the hot air flow and the outside air, but also facilitate the loading and unloading of the wire and the heat shrink tubing, thereby effectively enhancing the convenience of the heating process.

[0050] As a preferred embodiment of the present invention, a sealing ring 26 is fixedly installed on the bite disk 2, the heating groove 21 passes through the sealing ring 26, the sealing ring 26 is made of elastic material, and the axial distance between the two bite disks 2 is smaller than the outer diameter of the sealing ring 26 and larger than the inner diameter of the sealing ring 26.

[0051] In actual application, in order to further enhance the covering and isolation effect of the heating space, a sealing ring 26 is provided on the bite disk 2 in the present invention, and the axial distance between the two bite disks 2 is smaller than the outer diameter of the sealing ring 26 and larger than the inner diameter of the sealing ring 26. Therefore, during the rotation of the bite disk 2, the gap width between the two bite disks 2 is smaller than the thickness of the two sealing rings 26. Therefore, during the alignment of the two corresponding heating grooves 21, the sealing ring 26 is compressed, and then the deformation of the sealing ring 26 is utilized to enhance the isolation effect from the outside world after the two heating grooves 21 are aligned. At the same time, since the length of the wire is greater than the length of the heating groove 21, the sealing ring 26 elastically clamps the wire beyond the two ends of the heating groove 21, which on the one hand enhances the fixing effect of the wire, and on the other hand reduces the damage to the wire.

[0052] As a preferred embodiment of the present invention, the sealing ring 26 is inlaid with evenly distributed clamping pieces 27 , and the clamping pieces 27 extend into the heating groove 21 . The clamping pieces 27 are made of high temperature resistant elastic material.

[0053] The clamping sheet 27 is provided with uniformly distributed micro-holes, and the clamping sheets 27 correspond to each other in the two corresponding heating slots 21 .

[0054] Since the heat shrinkable tube can move axially on the wire before it is heat-shrunk, during the heat-drying process, when the combined wire and the heat shrinkable tube move to the gap between the two heating grooves 21, the wire first contacts the sealing ring 26 and the clamping piece 27, and the sealing ring 26 clamps both ends of the wire, and multiple clamping pieces 27 clamp part of the wire and the heat shrinkable tube located in the heating groove 21, so that when the hot air flow blows, the probability of the heat shrinkable tube moving axially on the wire is effectively avoided, so that the position of the shrunken heat shrinkable tube on the wire meets the requirements. At the same time, in order to reduce the influence of the clamping piece 27 on the heating effect of the heat shrinkable tube, the present invention provides evenly distributed micropores on the clamping piece 27 to facilitate the contact between the hot air flow and the heat shrinkable tube.

[0055] As a preferred embodiment of the present invention, a heat-insulating shell 3 is fixedly installed on the workbench 1, and the heat-insulating shell 3 is sleeved on the outside of the bite disk 2 and the sealing ring 26. The heat-insulating shell 3 is rotationally sealed with the sealing ring 26, and a through groove 31 is opened on the heat-insulating shell 3, and the through groove 31 is aligned with the gap of the bite disk 2.

[0056] A windshield curtain 32 is fixedly installed in the through groove 31 , and the windshield curtain 32 is used to block the air circulation inside and outside the heat insulation shell 3 .

[0057] During the rotation of the bite disk 2, the heating grooves 21 gradually overlap and then separate after heating. At this time, the temperature in the heating grooves 21 is relatively high. In order to avoid heat exchange between the heating grooves 21 and the outside air and to avoid safety hazards to the staff caused by the high-temperature heating grooves 21, the present invention provides an insulating shell 3 outside the bite disk 2 and the sealing ring 26. The bite disk 2 rotates in the insulating shell 3, and the wire passes through the through grooves 31 provided on the insulating shell 3. In conjunction with the windshield 32 installed in the through grooves 31, the interaction between the internal hot air and the outside air is effectively isolated, thereby reducing heat leakage. Under the action of the circulating pump 22, the airflow inside the insulating shell 3 is continuously circulated and heated, thereby reducing the heating burden of the electric heater 25 and effectively enhancing the energy-saving effect of the equipment.

[0058] As a preferred embodiment of the present invention, a partition 4 is slidably installed in the bite disk 2, and the partition 4 is sleeved on the outside of the distribution pipe 24. The partition 4 extends into the heating groove 21. The partition 4 is a T-shaped structure, and the smallest end of the partition 4 extends to the outside of the insulation shell 3. The partition 4 is used to adjust the opening length of the heating groove 21.

[0059] Since the lengths of the heat shrink tubing used on wires of different specifications are different, the lengths of the areas to be heated are different. In order to further reduce the size of the heating space, a partition 4 is slidably installed in the bite disk 2 in the present invention. The partition 4 extends into the heating groove 21, and the partition 4 slides laterally in the heating groove 21. By pushing the partition 4 to move axially in the bite disk 2, the opening of the distribution pipe 24 can be partially blocked, and the ventilation groove 23 and the heating groove 21 can be separated at the same time. Then, according to the heating process of the wire to be processed, the size of the opening of the distribution pipe 24 and the size of the hot air flow space can be flexibly adjusted to further enhance the energy-saving effect of the equipment.

[0060] As a preferred embodiment of the present invention, it also includes a synchronous delivery mechanism, which is installed on the workbench 1 and is used to deliver wires and heat shrinkable sleeves to the fixed-point heating mechanism;

[0061] The synchronous delivery mechanism includes a first conveyor belt 5, a second conveyor belt 51, an assembly plate 53 and a driving motor 54;

[0062] The first conveyor belt 5 and the second conveyor belt 51 can be installed on the workbench 1 in a liftable manner. The first conveyor belt 5 and the second conveyor belt 51 are both provided with evenly distributed placement grooves 52. The placement grooves 52 on the first conveyor belt 5 and the second conveyor belt 51 correspond to each other one by one. The first conveyor belt 5 and the second conveyor belt 51 respectively transport the wire and the heat shrink tubing through the placement grooves 52.

[0063] An assembly plate 53 is also installed on the workbench 1. The assembly plate 53 extends above the second conveyor belt 51. The assembly plate 53 is tilted and is used to push the heat shrink tubing to move toward the wire.

[0064] A driving motor 54 is installed on the workbench 1. The driving motor 54 and the first conveyor belt 5, the second conveyor belt 51, and the separator 4 are all belt-driven to drive the first conveyor belt 5, the second conveyor belt 51, and the bite plate 2 to move synchronously.

[0065] Specifically, the first conveyor belt 5 and the second conveyor belt 51 have multiple rotating rollers in their internal structures, one of which is directly connected to the output shaft of the driving motor 54, and a rotating roller close to the partition 4 is sleeved with a belt, and a pulley is slidably installed on the partition 4, and the belt is sleeved on the pulley, so that the driving motor 54, the first conveyor belt 5, the second conveyor belt 51, and the partition 4 form a transmission system.

[0066] The synchronous delivery mechanism also includes a wire box 55 and a sleeve disc 56, which are respectively located above the first conveyor belt 5 and the second conveyor belt 51. The bottoms of the wire box 55 and the sleeve disc 56 are both opened, and the opening width matches the diameter of the wire and the heat shrink tubing. The gap between the wire box 55 and the first conveyor belt 5 is smaller than the diameter of the wire, and the gap between the sleeve disc 56 and the second conveyor belt 51 is smaller than the diameter of the heat shrink tubing.

[0067] A translation platform 57 is fixedly installed on the workbench 1 . The translation platform 57 is located above the first conveyor belt 5 and the second conveyor belt 51 . The wire box 55 and the sleeve disc 56 are both slidably installed on the translation platform 57 .

[0068] In order to further enhance the convenience of the wire and heat shrink tubing drying process, a synchronous delivery mechanism is provided in the present invention. Under the action of the driving motor 54, the first conveyor belt 5, the second conveyor belt 51 and the partition 4 and the bite plate 2 rotate synchronously. During this process, the wires and heat shrink tubing in the wire box 55 and the tubing plate 56 fall one by one into the placement grooves 52 on the first conveyor belt 5 and the second conveyor belt 51 under the action of gravity. The placement spacing of the wires and the heat shrink tubing is controlled by the opening spacing of the placement grooves 52, and the wires and the heat shrink tubing are made to correspond one to one. Then, in the process of the second conveyor belt 51 carrying the heat shrink tubing, the heat shrink tubing and the assembly plate 53 produce relative movement, and under the limiting action of the assembly plate 53, the heat shrink tubing produces axial movement, and then the heat shrink tubing is moved. In order to push the heat shrink tube onto the wire, it should be noted that since the initial diameter of the heat shrink tube must be larger than the diameter of the wire, the diameter of the placement slot 52 on the first conveyor belt 5 is smaller than the placement slot 52 on the second conveyor belt 51. In the initial preparation work of production, the staff adjusts the position of the wire box 55 and the sleeve disk 56 on the translation table 57, and then adjusts the initial position of the wire and the heat shrink tube on the first conveyor belt 5 and the second conveyor belt 51, so as to facilitate the installation of the heat shrink tube on the wire. At the same time, because the opening spacing of the placement slot 52 matches the spacing of the heating slot 21 on the bite disk 2, during the transportation process, the position of the combination of the wire and the heat shrink tube enters the heating slot 21 one by one for heating, thereby making the heating process of the wire and the heat shrink tube more convenient.

[0069] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
