[0028] Example 1

[0029] Reference Figure 1-3 A heating device for batch heating of heat shrinkable tubes includes a heater 10 and a carrier 20. One side of the heater 10 has a material port 12. A cover plate 11 sealed to the material port 12 is hingedly provided on the side of the material port 12 of the heater 10. The carrier 20 is configured to move back and forth inside and outside the heater 10 so as to load or unload materials on the carrier 20. A plurality of support brackets 21 arranged up and down are provided on both sides of the top of the carrier 20. The left and right adjacent support brackets 21 support the two ends of a plurality of rod-shaped members covered with heat shrinkable tubes.

[0030] The heater 10 is the core component of the device. The heater 10 is provided with heating tubes on the upper and lower sides for heating the heat shrink tube. A material port 12 is provided on one side for placing or removing the heat shrink tube. A cover plate 11 is hinged on the side of the material port 12. This cover plate can seal the material port when not in use, keep the temperature inside the heater stable, and prevent heat loss. The carrier 20 is designed to be able to move back and forth inside and outside the heater 10. This mobility allows the operator to conveniently load and unload materials, that is, place the heat shrink tube to be heated or remove the heat shrink tube that has been heated. A plurality of support brackets 21 arranged up and down are provided on both sides of the top of the carrier 20. These support brackets 21 are used to support and fix the heat shrink tube to ensure that the heat shrink tube remains stable during the heating process and avoid displacement due to thermal expansion and contraction or gravity. The two ends of a plurality of rod-shaped members with heat shrink tubes are supported between the adjacent support brackets 21 on the left and right. This design allows multiple heat shrink tubes to be fixed and heated at the same time, improving the heating efficiency.

[0031] When the heat shrink tube needs to be heated, the operator puts the heat shrink tube to be heated on the rod-shaped member and places it on the support 21 of the support frame 20. The support frame 20 is then pushed into the heater 10, and the cover plate 11 seals the material port to keep the heat. The heat inside the heater is evenly transferred to the heat shrink tube, causing it to shrink and fit tightly on the rod-shaped member. After the heating is completed, the support frame 20 is pulled out of the heater, and the operator can take out the heated heat shrink tube. This design not only improves the heating efficiency, but also ensures the quality and consistency of the heat shrink tube heating through uniform heating and automated operation.

[0032] like Figure 2 or Figure 3 As shown, the top of the support 21 is provided with a notch 22 adapted to the end of the rod-shaped member.

[0033] The top of the support 21 is specially designed with notches 22, which are adapted to the shape and size of the ends of the rod-shaped member. The notches 22 can tightly fix the ends of the rod-shaped member, providing additional stability. With the design of the notches 22, the ends of the rod-shaped member can be more accurately positioned and fixed. This design helps to ensure that the heat shrink tube will not be offset due to the movement or rotation of the rod-shaped member during the heating process.

[0034] In addition, the notches include but are not limited to U-shaped, V-shaped and square, and notches of different shapes can provide different fixing effects. For example, a U-shaped notch may provide a wider contact surface, which helps to stabilize the rod-shaped member; a V-shaped notch may be more suitable for slender rod-shaped members and provide a tighter clamping; a square notch may be suitable for situations where right-angle fixing is required.

[0035] During the heating process, the two ends of the rod-shaped member are placed in the notches 22 on the top of the support 21. The shape and size of the notches 22 match the ends of the rod-shaped member, thereby ensuring that the rod-shaped member does not slide or rotate during the heating process.

[0036] like Figure 3 As shown, guide rods 23 are respectively provided through both ends of the support 21 , and the support 21 is configured to move on the guide rods 23 .

[0037] Guide rods 23 are provided at both ends of the support 21, and these guide rods provide accurate movement paths and positioning for the support. The support 21 is configured to be movable on the guide rods 23, which means that the support can move horizontally along the guide rods or stop after the guide rods move to meet different operation requirements.

[0038] During the heating process, the support 21 is positioned and moved by the guide rods 23 at both ends. The guide rods provide a precise path so that the support can be adjusted to different positions of the guide rods 23 by movement to expand or reduce the distance between adjacent support 21 and meet the heating requirements of heat shrink tubes of different lengths.

[0039] like Figure 3 As shown, the adjacent bearing brackets 21 and the guide rods 23 on the same side are integrally arranged, and both ends of the guide rods 23 are fixedly connected to the side frames 24 arranged on both sides of the top of the bearing frame 20.

[0040] The guide rods 23 on the same side of adjacent support brackets 21 are integrally arranged, which means that these guide rods are manufactured and installed as a continuous component rather than independent, separate components. This design can reduce the complexity of assembly and may improve the stability of the overall structure. The two ends of the guide rods 23 are fixedly connected to the side frames 24 on both sides of the top of the support frame 20. This connection method ensures the stability of the guide rods and the accuracy of the support bracket 21 when moving. The side frames 24 not only provide fixing points for the guide rods 23, but also enhance the structural strength of the support frame 20. The setting of the side frames helps the support frame to remain stable when moving inside or outside the heater 10.

[0041] The guide rods 23 on the same side of adjacent support brackets 21 are integrally arranged, and this design enables the support bracket to move along a continuous path, reducing possible friction and vibration. The two ends of the guide rod 23 are fixedly connected to the side frame 24, ensuring the stability and accuracy of the support bracket when moving inside or outside the heater 10.

[0042] During the heating process, the support 21 moves along the guide rod 23 on the side frame 24 to achieve the loading and unloading operations of the heat shrink tube. Due to the integrity and fixity of the guide rod and the side frame, the support will not deviate during movement, ensuring accurate positioning and uniform heating of the heat shrink tube during heating. This design improves the reliability of the equipment and the convenience of operation, while also ensuring the quality and efficiency of the heat shrink tube heating process.

[0043] Example 2

[0044] like Figure 4 As shown, different from Example 1, the guide rods 23 on the same side of adjacent bearing brackets 21 are two disconnected guide rods 23, and both ends of the guide rods 23 are fixedly connected to the side frame 24 and the center column 25 of the bearing frame 20.

[0045] The guide rods 23 on the same side of adjacent bearing brackets 21 are arranged in a disconnected manner. Therefore, there are two independent guide rods 23 on the same side of each bearing bracket 21, rather than a continuous guide rod. The two ends of each guide rod 23 are respectively fixedly connected to the side frame 24 and the middle column 25 of the bearing frame 20. The middle column 25 is a newly added component used to enhance the stability of the guide rods and the overall structure of the bearing frame. The middle column 25 not only provides an additional fixing point for the guide rods 23, but also helps to enhance the rigidity and stability of the bearing frame 20, especially when the bearing frame needs to carry a heavier heat shrink tube.

[0046] In Embodiment 2, the guide rods 23 on the same side of adjacent bearing brackets 21 are disconnected, and the two ends of each guide rod are respectively fixedly connected to the side frame 24 and the center column 25. This design allows the bearing brackets 21 to move or limit along the independent guide rods.

[0047] When loading or unloading operations are required, the support bracket 21 can move along these guide rods, and the middle column 25 provides additional support to ensure the stability of the support bracket during movement. Since the guide rods 23 are disconnected, each support bracket 21 can move independently, which may help to more flexibly adjust the position of the support bracket to accommodate heat shrink tubes of different sizes and shapes. At the same time, the presence of the middle column 25 provides additional rigidity and stability for the entire support frame, ensuring accurate positioning and uniform heating of the support bracket during heating. This design further improves the reliability of the equipment and the convenience of operation.

[0048] Example 3

[0049] It also includes a lower supporting platform 30 , the top of which is flush with the bottom of the inner cavity of the heater 10 , and the movement of the carrier 20 allows the carrier 20 to move back and forth between the heater 10 and the lower supporting platform 30 .

[0050] In Example 3, a lower support platform 30 is newly added, and its top is arranged flush with the bottom of the inner cavity of the heater 10. This design allows the lower support platform 30 to serve as an extension of the inner cavity of the heater 10, providing additional support and movement space for the carrier 20. The movement of the carrier 20 allows it to move back and forth between the heater 10 and the lower support platform 30. The carrier can not only move inside the heater, but also extend to the lower support platform outside the heater, which increases the flexibility of operation and the efficiency of space utilization. By arranging the lower support platform outside the heater, the operator can more conveniently perform loading and unloading operations.

[0051] In Embodiment 3, the top of the lower support platform 30 is flush with the bottom of the inner cavity of the heater 10, forming a continuous operating platform. The support frame 20 can move freely between the lower support platform 30 inside and outside the heater 10, thereby expanding the operating space.

[0052] When the heat shrink tube needs to be placed in the heater 10 for heating, the carrier 20 can be moved into the heater and moved to a suitable position in the inner cavity of the heater. After the heating is completed, the carrier can be moved to the lower support 30, so that the operator can take out the heated heat shrink tube. This design not only improves the convenience of operation, but also enhances the flexibility and adaptability of the equipment.

[0053] In addition, the presence of the lower support platform 30 also helps to protect the safety of the operator, because it can serve as a buffer area for the heater 10, reducing the risk of direct contact with the high temperature area. At the same time, the lower support platform 30 can also be used as a temporary storage place for the heated heat shrink tubes until they are further processed or packaged. This design further improves the practicality and safety of the entire heating device.

[0054] like Figure 5 As shown, a plurality of rollers 26 are disposed at the bottom of the carrier 20 , and tracks A13 and tracks B31 corresponding to the rollers 26 are respectively disposed on the heater 10 and the lower support platform 30 .

[0055] A plurality of rollers 26 are provided at the bottom of the carrier 20. These rollers are key components for the movement of the carrier, allowing the carrier to move smoothly between the heater 10 and the lower support platform 30. The heater 10 and the lower support platform 30 are respectively provided with a track A13 and a track B31 corresponding to the rollers 26. Track A and track B are guide rails designed for the rollers 26 to ensure that the carrier moves stably along a predetermined path when moving.

[0056] In Embodiment 3, a plurality of rollers 26 are installed at the bottom of the carrier 20, and these rollers match the track A13 and track B31 on the heater 10 and the lower support platform 30. When the carrier needs to move inside or outside the heater, the rollers roll along the track A and track B to guide the carrier to move smoothly.

[0057] Example 4

[0058] like Figure 6 As shown, different from the third embodiment, a plurality of rollers 26 are provided at the bottom of the carrier 20, and guide grooves A14 and guide grooves B32 corresponding to the rollers 26 are respectively provided on the heater 10 and the lower support platform 30.

[0059] The bottom of the carrier 20 is provided with a plurality of rollers 26, which are key components for the movement of the carrier, allowing the carrier to move smoothly between the heater 10 and the lower support platform 30. Different from Example 3, the heater 10 and the lower support platform 30 are respectively provided with guide grooves A14 and guide grooves B32 corresponding to the rollers 26. The guide grooves are guiding structures designed for the rollers to ensure that the carrier moves stably along a predetermined path when moving. The use of the guide grooves improves the stability and guidance of the movement of the carrier, reduces errors caused by friction or offset, and provides a clearer movement path.

[0060] When the carrier needs to move inside or outside the heater, the rollers roll along guide grooves A and B to guide the carrier to move smoothly. The design of the guide grooves not only improves the stability of the carrier movement, but also reduces the friction and noise that may be generated by the rollers during movement, thereby improving the operating efficiency of the entire system.

[0061] It should be noted that both ends of the guide groove A14 and the guide groove B32 are respectively provided with a limit block with a slope (not marked in the figure), and the limit block on the guide groove A14 or the guide groove B32 is used to limit the two adjacent rollers on the same side of the bottom of the carrier 20 to prevent excessive rolling. In addition, in Example 3, both ends of the track A13 or the track B31 are also provided with a limit block with a slope to limit the two adjacent rollers on the same side of the bottom of the carrier 20 to prevent excessive rolling.

[0062] In addition, the movement mechanisms in Embodiment 3 and Embodiment 4 can be cited in Embodiment 1 and Embodiment 2.

[0063] In addition, the guide rod 23 is not only used to guide the movement of the support 21, but also has a limiting function to prevent the support from exceeding a predetermined range when moving inside the heater. In order to achieve the limiting function, at least one of the guide rods 23 is designed as a screw, and its thread is adapted to the nut 27 that rotates at the end of the support 21. This design allows the movement and position of the support to be controlled by rotating the nut. The use of the screw and the nut provides a method for accurately controlling the position of the support. By rotating the nut, the position of the support in the heater can be accurately adjusted to ensure that it does not exceed the predetermined working range.

[0064] In the embodiment, the guide rod 23 is given a limiting function to ensure that the support bracket 21 does not exceed a predetermined range when moving inside the heater 10. This limiting function is achieved by designing at least one guide rod as a screw rod, and the thread of the screw rod is adapted to the nut 27 at the end of the support bracket.

[0065] When the position of the support needs to be adjusted, the operator can push the support 21 to make the nut 27 bear force on the screw rod. Since the nut 27 and the support 21 are rotatably arranged and the screw rod is fixedly connected to the side frame 24, the rotation of the nut will move along the screw thread, thereby pushing the support to move to the desired position along the guide rod. Since the cooperation of the screw rod and the nut provides precise control, the operator can ensure that the movement of the support inside the heater is controllable and will not exceed the predetermined working range.

[0066] Furthermore, the guide rods 23 at both ends of the support 21 are screw rods, and nuts 27 adapted for threaded connection with the screw rods are rotatably provided at the ends of the support 21 .

[0067] In this design, the guide rods 23 at both ends of the support 21 are screw rods, and the threads on the screw rods are adapted to the nuts 27 at the ends of the support. This design allows the support to move more stably along the guide rods.

[0068] When the position of the support needs to be adjusted, the operator can do so by rotating the nut 27. The rotation of the nut moves along the thread of the screw rod, pushing the support to move to the desired position along the guide rod. Since the guide rods at both ends are screw rods, both ends of the support can move in a balanced manner, thereby providing more flexible movement and positioning capabilities.

[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
