Description

Technical Field

[0001] This application relates to the field of heat shrink tubing drying equipment, and in particular to an automatic heat shrink tubing positioning drying machine. Background Technology

[0002] In the wire and cable processing industry, heat shrink tubing, as an important insulating material, is widely used at the joints of various wires and cables to provide waterproofing, dustproofing, and electrical insulation protection. Traditional methods of heating heat shrink tubing often involve manual operation, such as using a heat gun or torch to locally heat the tubing, causing it to shrink and tightly wrap around the wire. However, this method has several shortcomings:

[0003] Uneven heating: Manual heating makes it difficult to ensure that the heat shrink tubing is heated evenly, which can easily lead to local overheating or insufficient shrinkage, affecting the insulation effect and appearance.

[0004] Inefficiency: Manual operation requires processing the heat shrink tubing on each wire one by one, which is time-consuming and labor-intensive. Especially in mass production, inefficiency becomes a key factor restricting production capacity.

[0005] Safety hazards: Using open flames or high-temperature hot air guns for heating poses a risk of fire and burns, and threatens the safety of operators.

[0006] Inaccurate positioning: Without a precise positioning device, the heat shrink tubing is prone to shifting during the heating process, resulting in inaccurate heating position and further affecting the insulation effect. Utility Model Content

[0007] The purpose of this application is to provide an automatic heat shrink tubing positioning and drying machine that can automatically, efficiently, safely and accurately heat shrink tubing.

[0008] To achieve the above objectives, this application provides the following technical solution:

[0009] An automatic heat shrink tubing positioning and drying machine includes an upper drying mechanism, a lower drying mechanism, a transverse drive device, and a wire positioning device. The upper and lower drying mechanisms are arranged vertically opposite each other. The wire positioning device is located on one side of the upper and lower drying mechanisms. The transverse drive device is used to drive the upper and lower drying mechanisms to the wire positioning device to heat shrink the heat shrink tubing on the wire.

[0010] In one embodiment, a hot-drying cover-closing device is also included. The hot-drying cover-closing device is disposed on the upper hot-drying mechanism or the lower hot-drying mechanism. The hot-drying cover-closing device includes a hot-drying cover and a hot-drying cover-closing driving device. The hot-drying cover-closing driving device is used to drive the hot-drying cover to cover the hot-drying area between the upper hot-drying mechanism and the lower hot-drying mechanism.

[0011] In one embodiment, the upper heating mechanism includes an upper hot air generating device and an upper air outlet. The upper hot air generating device is connected to the upper air outlet. The upper hot air generating device generates hot air that enters the upper air outlet. The bottom of the upper air outlet is provided with an upper air outlet hole for guiding the hot air to the heat shrink tubing on the wire.

[0012] In one embodiment, the upper air outlet is provided with an upper air outlet limiting part, which is configured to restrict the flow path of hot air in order to reduce the air outlet area of ​​the upper air outlet in non-target areas.

[0013] In one embodiment, an upper air outlet baffle is provided at the bottom of the upper air outlet, and an upper air outlet clearance groove is provided on the upper air outlet baffle. The upper air outlet clearance groove cooperates with the upper air outlet hole to restrict the flow path of hot air and reduce the air outlet area of ​​non-target areas.

[0014] In one embodiment, a height adjustment device is also included, which is used to adjust the distance between the upper heating mechanism and the lower heating mechanism.

[0015] In one embodiment, a housing is also included, which is configured to cover the exterior of the upper and lower heating mechanisms and partially cover the bottom of the wire positioning device to form a relatively enclosed space.

[0016] In one embodiment, a cooling fan is provided on the front side of the housing, located below the wire positioning device; a heat dissipation vent is provided on the rear side of the housing, and the cooling fan is used to exhaust the heat generated by the upper heating mechanism, the lower heating mechanism, the wire positioning device and the wire inside the housing from front to back.

[0017] In one embodiment, a control box is also included, which is used to control the operation of the upper heating mechanism and the lower heating mechanism. A heat insulation layer is provided between the control box and the upper heating mechanism and the lower heating mechanism. The control box and the upper heating mechanism and the lower heating mechanism are either separate or integrated.

[0018] In one embodiment, temperature sensing devices are respectively installed in the upper and lower heating mechanisms to monitor the temperature during the heating process in real time.

[0019] The beneficial effects of this application are:

[0020] (1) By setting the upper and lower heating mechanisms in opposite directions, this application can ensure that the heat shrink tubing is heated evenly during the heat shrinking process, effectively avoiding the problems of local overheating or insufficient shrinkage. This not only improves the insulation performance of the heat shrink tubing, but also greatly enhances its aesthetics and durability.

[0021] (2) The introduction of the transverse drive device in this application enables the upper and lower heating mechanisms to automatically move to the wire positioning device to quickly and accurately heat the heat shrink tubing on the wire. This automated design greatly improves production efficiency, especially in large-scale production environments, where it can significantly reduce manual intervention, lower labor intensity, and increase overall production capacity.

[0022] (3) The design of the wire positioning device in this application ensures that the heat shrink tubing remains stable and does not shift during the heat shrinking process, thus ensuring the accuracy of the heating position. This not only improves the processing quality of the heat shrink tubing but also reduces the scrap rate caused by inaccurate positioning, thereby lowering production costs.

[0045] The terminology used in the implementation section of this application is only for explaining specific embodiments of this application and is not intended to limit this application. The implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0046] like Figure 1 As shown, an automatic heat shrink tubing positioning and drying machine includes a housing 1, a wire positioning device 2, a control box 3, an upper drying mechanism 4, a lower drying mechanism 5, and a transverse drive device 6 disposed within the housing 1.

[0047] like Figure 2As shown, the upper heating mechanism 4 and the lower heating mechanism 5 are arranged opposite each other, the wire positioning device 2 is located on one side of the upper heating mechanism 4 and the lower heating mechanism 5, and the transverse drive device 6 is used to drive the upper heating mechanism 4 and the lower heating mechanism 5 to the wire positioning device 2 to heat-dry and heat-shrink the heat shrink tube on the wire 7.

[0048] During operation, the wire to be heated is first precisely positioned at its predetermined location using the wire positioning device 2. Next, the lateral drive device 6 is activated, driving the upper heating mechanism 4 and the lower heating mechanism 5 to move simultaneously towards the wire positioning device 2. Subsequently, the heating elements inside the two heating mechanisms begin to operate, evenly transferring heat to the heat shrink tubing, causing it to gradually shrink and tightly wrap around the wire.

[0049] The specific implementation of the transverse drive device 6 is not limited to a specific technology, but can be achieved by using a variety of different technologies according to actual needs, including but not limited to pneumatic drive, electric drive or hydraulic drive.

[0050] like Figure 3 As shown, the wire positioning device 2 mainly includes a positioning base plate 21, which is made of a high-temperature resistant and high-strength material to ensure that it will not deform or be damaged during the heating process. The positioning base plate 21 is provided with multiple positioning grooves 22 for positioning the wire. These positioning grooves 22 are carefully designed according to the diameter and arrangement of the wire to ensure that the wire can be accurately and stably placed in the predetermined position. Furthermore, the positioning base plate 21 is also provided with a hot air passage 23, which is located below the positioning grooves 22 and corresponds to the hot air outlet of the lower hot air drying mechanism 5. The design of the hot air passage 23 allows the hot air generated by the lower hot air drying mechanism 5 to pass smoothly upwards, directly heating the lower part of the wire to be heated, thereby improving heating efficiency and uniformity. In use, firstly, a suitable positioning groove 22 is selected according to the specifications and arrangement of the wire, and the wire is placed into the groove in sequence. Then, the lower hot air drying mechanism 5 is activated, and hot air is blown upwards through the hot air passage 23, directly heating the lower part of the wire. Simultaneously, the upper heating mechanism 4 can also be activated to heat the upper part of the wire, thereby achieving comprehensive and uniform heating of the wire. During the heating process, the positioning device can ensure the stable positioning of the wire, avoiding quality problems caused by displacement of the heat shrink tubing.

[0051] like Figure 4 As shown, in one embodiment, a hot drying cover closing device 8 is also included. The hot drying cover closing device 8 is disposed on the upper hot drying mechanism 4 or the lower hot drying mechanism 5. The hot drying cover closing device 8 includes a hot drying cover 81 and a hot drying cover closing drive device 82. The hot drying cover closing drive device 82 is used to drive the hot drying cover to cover the hot drying area between the upper hot drying mechanism 4 and the lower hot drying mechanism 5.

[0052] Taking the example of the heat-drying cover closing device 8 being installed on the lower heat-drying mechanism 5, the heat-drying cover closing drive device 82 can be pneumatic, electric, or hydraulic, depending on the overall design and usage requirements of the equipment. The drive device should be able to precisely control the opening and closing speed of the heat-drying cover, as well as the pressure during closing, to ensure that the heat-drying cover fits tightly between the upper heat-drying mechanism 4 and the lower heat-drying mechanism 5, forming a closed heat-drying environment. In use, first, the wire is placed into the positioning groove 22 according to its specifications and arrangement. Then, the lower heat-drying mechanism 5 and the upper heat-drying mechanism 4 are activated, and simultaneously, the heat-drying cover closing drive device 82 drives the heat-drying cover upwards until it covers the heat-drying area. During the heating process, the heat-drying cover effectively reduces heat loss, allowing the heat to be more concentrated on the heat-shrink tubing, improving heating efficiency and uniformity. After heating is complete, the hot drying hood closing drive device 82 drives the hot drying hood downwards, and the lateral movement drive device 6 immediately drives the upper hot drying mechanism 4 and the lower hot drying mechanism 5 to the wire heating area for heating. This application enables the upper hot drying mechanism 4 and the lower hot drying mechanism 5 to quickly heat the hot drying area during the preheating stage, shortening the heating time and improving production efficiency. The timely closing of the hot drying hood effectively reduces heat loss and improves heating efficiency and uniformity.

[0053] like Figure 6 As shown, in one embodiment, the upper heating mechanism 4 includes an upper hot air generating device 41 and an upper air outlet 42. The upper hot air generating device 41 is connected to the upper air outlet 42. The upper hot air generating device 41 generates hot air that enters the upper air outlet 42. The bottom of the upper air outlet 42 is provided with an upper air outlet hole 43 for guiding the hot air to the heat shrink tubing on the wire.

[0054] like Figure 5 As shown, the upper hot air generating device 41 includes an upper fan 411, an upper heating element 412, an upper air supply duct 413, and an upper buffer box 414. The upper fan 411 is connected to one side of the upper buffer box 414, and the other side of the upper buffer box 414 is connected to the upper heating element 412. The upper air supply duct 413 is sleeved on the upper heating element 412 and connected to the upper air outlet 42. The upper fan 411, upper buffer box 414, upper heating element 412, upper air supply duct 413, and upper air outlet 42 are kept on the same horizontal line, which helps to maintain the stability and smoothness of airflow.

[0055] like Figure 7As shown, in one embodiment, an upper air outlet 42 is provided with an upper air outlet limiting part 44, configured to restrict the flow path of hot air to reduce the air outlet area of ​​the upper air outlet 42 in non-target areas. The upper air outlet limiting part 44 is configured as a series of guide plates or baffles that form narrow air outlet channels inside the upper air outlet 42. These channels restrict the flow path of hot air, ensuring that hot air can be blown more concentratedly onto the heat shrink tubing on the wire, rather than being dispersed into non-target areas.

[0056] like Figure 8 As shown, in one embodiment, an upper air outlet baffle 45 is provided at the bottom of the upper air outlet 42, and an upper air outlet clearance groove 46 is provided on the upper air outlet baffle 45. The upper air outlet clearance groove 46 cooperates with the upper air outlet hole 43 to form a specific hot air flow channel. These channels not only restrict the flow path of hot air, but also reduce the air outlet area of ​​non-target areas, so that the hot air can act more accurately on the heat shrink tubing.

[0057] The lower heating mechanism 5 has the same structure as the upper heating mechanism 4, so it will not be described again.

[0058] like Figure 9 As shown, in one embodiment, a height adjustment device 9 is also included, which is used to adjust the distance between the upper heating mechanism 4 and the lower heating mechanism 5.

[0059] The height adjustment device 9 can be manual or automatic, and the specific design is as follows:

[0060] Manual adjustment: The upper heating mechanism 4 is mounted on an adjusting plate 91, which has an adjusting groove 92. By loosening the bolts, the upper heating mechanism 4 can be moved along the adjusting groove 92, thereby changing the distance between it and the lower heating mechanism 5. Once the distance is adjusted to the correct position, the bolts are tightened to lock the position. The manual adjustment method is simple and intuitive, allowing operators to easily adjust the height according to actual needs without complicated operations.

[0061] like Figure 11 As shown, another method is to install the upper heating mechanism 4 on the adjusting plate 91. The adjusting plate 91 is provided with an adjusting groove 92. In addition, an adjusting screw 93 is set on the upper heating mechanism. By rotating the adjusting screw 93, the upper heating mechanism 4 is lifted. After the distance is adjusted to the correct position, the bolt is tightened to lock the position. This method is more convenient for adjustment.

[0062] Automatic Adjustment Method: The height adjustment device 9 uses drive components such as cylinders, electric push rods, or hydraulic cylinders. These components are connected to the upper heating mechanism 4, and the height of the upper heating mechanism 4 can be precisely adjusted by controlling the extension and retraction of the drive components. The automatic adjustment method can be integrated with the equipment's control system to achieve automated and intelligent height adjustment. The operator only needs to input the target height or select a preset mode on the control panel, and the equipment can automatically complete the height adjustment.

[0063] By introducing the height adjustment device 9, this embodiment achieves the following beneficial effects: the height adjustment device 9 allows the equipment to flexibly adapt to the processing requirements of wires of different specifications and thicknesses. By precisely adjusting the distance between the upper heating mechanism 4 and the lower heating mechanism 5, it can be ensured that hot air acts more evenly on the heat shrink tubing, improving heating efficiency and processing quality.

[0064] like Figure 10 As shown, in one embodiment, the housing 1 is configured to cover the exterior of the upper heating mechanism 4 and the lower heating mechanism 5, and also partially cover the bottom of the wire positioning device 2, forming a relatively enclosed space. This design not only protects the internal components of the equipment from external interference but also reduces heat loss to the outside, improving heating efficiency.

[0065] like Figure 10 As shown, in one embodiment, a cooling fan 11 is provided on the front side of the housing 1. In this embodiment, two fans are provided, located below the wire positioning device 2. A heat dissipation vent is provided on the rear side of the housing 1. The cooling fans 11 are used to exhaust the heat generated by the upper heating mechanism 4, the lower heating mechanism 5, the wire positioning device 2, and the wire inside the housing 1 from front to back. The cooling fans 11 are located on the front side of the housing 1, below the wire positioning device 2. The cooling fans 11 help reduce the operating temperature of the equipment by drawing in external cool air and blowing it into the equipment.

[0066] like Figure 12 As shown, in this embodiment, cooling fans 11 and heat dissipation slots are respectively provided on the left and right sides, rear side, and top of the housing 1. The height of the cooling fans on the left and right sides and rear side of the housing 1 is higher than the height of the cooling fan on the front side of the housing. In this embodiment, heat dissipation slots are provided on the left and right sides of the housing 1, and a taller cooling fan 11 is provided on the rear side. Since the hot air dryer is used in high-temperature fields, a specific airflow path is designed: cold air enters from the front side of the housing, passes through the interior of the housing, and is passively dissipated by the cooling fans and heat dissipation slots on the left and right sides and rear side, forming effective convection cooling.

[0067] In one embodiment, the control box 3 controls the operation of the upper heating mechanism 4 and the lower heating mechanism 5. It integrates key components such as control circuits, power modules, and user interfaces. A heat insulation layer 12 is provided between the control box 3 and the upper and lower heating mechanisms 4 and 5 to prevent high temperatures from damaging the electronic components inside the control box 3 and to ensure the stable operation of the control box 3. The control box 3 has intelligent control functions and can automatically adjust the heating power and working time of the heating mechanisms according to preset processing parameters and temperature curves, achieving precise temperature control and automation of the processing.

[0068] The control box can be either separate from or integrated with the upper and lower heating mechanisms. In an integrated design, the control box is combined with the upper and lower heating mechanisms to form an inseparable whole. In a separate design, the control box is separate from the upper and lower heating mechanisms, and they can be installed and connected independently.

[0069] In one embodiment, temperature sensors are installed in both the upper heating mechanism 4 and the lower heating mechanism 5 to monitor the temperature during the heating process in real time. These temperature sensors accurately reflect the temperature of the heating area, providing real-time temperature data to the control box 3. The temperature sensors are connected to the control box 3 to form a closed-loop control system. When the temperature deviates from the preset range, the control box 3 will adjust the heating power of the heating mechanism or shut down the heating element in a timely manner based on the feedback signal from the temperature sensors to ensure that the temperature remains stable within the set range. The temperature sensors also have an over-temperature protection function. When the temperature reaches or exceeds the set safety limit, the control box 3 will immediately cut off the heating power to prevent the equipment from overheating and causing damage or safety accidents.
