Abstract
Description
Technical Field
[0001] This application belongs to the field of coating hot melt processing technology, specifically relating to hot melt equipment. Background Technology
[0002] For coatings with poor fluidity at room temperature, such as modified bitumen waterproof coatings commonly used in building waterproofing, heating is required to melt them and improve their fluidity for easier application. Currently, most commercially available rapid heating devices are heaters with disc-type electric heating elements. During use, the contact area between the heating element and the coating is relatively large, resulting in a slow sinking speed, low heating efficiency, and an inability to achieve uniform heating, easily causing localized overheating or undercooling. Utility Model Content
[0003] In view of at least one of the above-mentioned defects or deficiencies in the prior art, this application provides a hot-melt device that can achieve dispersed and uniform heating of the coating and enable the heating device to quickly sink to the bottom of the coating, which is beneficial to improving the hot-melt efficiency.
[0004] To achieve the above objectives, this application provides a hot-melt apparatus, comprising:
[0005] The heating device includes multiple heating rods and a fixed flange. The fixed flange has multiple flange connection holes arranged in a circumferential array. The multiple heating rods are all arranged vertically and are respectively inserted into the multiple flange connection holes.
[0006] A lifting and adjusting mechanism is used to adjust the heating device in height so that the plurality of heating rods can be vertically inserted into the coating to be heated.
[0007] In some embodiments, the bottom end of the heating rod is formed into a tapered tip.
[0008] In some embodiments, the lifting adjustment mechanism includes a guide rod arranged vertically and a sliding member that slides with the guide rod. The fixed flange is connected to the sliding member, so that the heating device can be displaced downward under its own gravity.
[0009] In some embodiments, the sliding element is a linear bearing.
[0010] In some embodiments, the lifting and adjusting mechanism further includes a support arm arranged laterally, and the fixed flange is fixedly connected to the sliding member through the support arm.
[0011] In some embodiments, the heating rod includes a heating rod core and a hollow sleeve sleeved outside the heating rod core, the hollow sleeve being inserted into the flange connection hole.
[0012] In some embodiments, the heating rod is detachably inserted into the flange connection hole.
[0013] In some embodiments, the fixed flange is further provided with a probe connection hole, and the heating device further includes a temperature probe, which is inserted into the probe connection hole.
[0014] In some embodiments, the hot-melt equipment includes a movable base, and the lifting adjustment mechanism is disposed on the base.
[0015] In some embodiments, the hot-melting equipment further includes a control box, which is equipped with a controller for controlling the start and stop of the heating device, and both the control box and the heating device are mounted on the lifting and adjusting mechanism for synchronous lifting and lowering.
[0016] Through the above technical solution, multiple heating rods in the hot-melt equipment can be distributed in a dispersed manner on the fixed flange. When the coating to be heated is inserted, it can achieve an all-round heating effect, avoiding local overheating or undercooling. At the same time, multiple heating rods can be inserted vertically into the coating to be heated, thereby accelerating the sinking speed of the multiple heating rods. Therefore, during coating application, using the hot-melt equipment of this application to hot-melt the coating can improve the overall heating efficiency and hot-melt effect, resulting in a coating with better flowability.

[0026] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.
[0027] The present application will now be described in detail with reference to the accompanying drawings and exemplary embodiments.
[0028] Modified bitumen waterproof coatings are made from materials such as bitumen and rubber powder through high-temperature modification. After cooling, they are solid or paste-like at room temperature with very poor fluidity. During the coating application process, they need to be melted by heating to give them good fluidity, making them easy to apply.
[0029] Most existing paint heating devices use disc-shaped electric heating tubes as heating elements. In other words, straight tubular heating tubes are bent into spiral, disc, or planar spiral shapes to increase the contact area with the paint. During use, the disc-shaped heating tube needs to be lowered to the bottom of the paint to be heated, transferring heat through conduction and convection. However, due to the curvature of the coiled portion, uneven power density can occur, leading to localized overheating and carbonization of the paint. This usually requires the use of a stirring device to address the overheating problem. Furthermore, the large contact area with the paint during lowering results in a slow descent speed, making it difficult to quickly reach the bottom of the paint for heating.
[0030] In view of this, an exemplary embodiment of this application provides a hot-melting device that can avoid overheating and carbonization and effectively improve heating and melting efficiency.
[0031] like Figure 1 As shown, the hot-melt equipment mainly includes a heating device and a lifting and adjusting mechanism. The heating device includes multiple heating rods 1 and a fixed flange 2. The fixed flange 2 has multiple flange connection holes 201 arranged in a circumferential array. The multiple heating rods 1 are all arranged vertically and inserted into the multiple flange connection holes 201 respectively. The heating device can be installed as a whole on the lifting and adjusting mechanism. The height of the heating device can be adjusted by raising and lowering the lifting and adjusting mechanism, so that the multiple heating rods 1 can be vertically inserted into the coating to be heated.
[0032] Therefore, the hot-melt equipment of this exemplary embodiment can heat the coating material from all directions by uniformly arranging multiple heating rods 1 on the fixed flange 2, thus effectively avoiding localized overheating and carbonization or undercooling and low fluidity of the coating material. Simultaneously, under the adjustment of the lifting mechanism, the multiple heating rods 1 can be inserted vertically into the coating material. Due to the small end face area of the heating rods 1, the resistance of the coating material to the heating rods 1 is reduced, thereby accelerating the sinking speed of the multiple heating rods 1, improving the overall heating efficiency and hot-melt effect, and contributing to the preparation of coatings with better fluidity.
[0033] It is understandable that when using a container of a certain capacity to hold the coating to be heated, in order to heat the coating from all directions, multiple heating rods 1 can be evenly distributed inside the container when inserted. Therefore, the number and arrangement of the multiple heating rods 1 can be set according to the actual size of the container, and this application does not limit this. Optionally, each heating rod 1 is configured to be detachably inserted into any flange connection hole, thereby enabling various arrangement methods for different numbers of heating rods 1 in different positions.
[0034] In an optional or preferred embodiment, the bottom end of the heating rod 1 can be designed as a tapered tip, which can further reduce the end face area of the heating rod 1, reduce the resistance of the coating to the heating rod 1, further accelerate the sinking speed of the heating rod 1, and achieve the effect of rapid heat melting of the coating.
[0035] In an optional or preferred embodiment, the heating rod 1 includes a heating rod core and a hollow sleeve fitted over the heating rod core, the hollow sleeve being inserted into the flange connection hole 201. The heating rod core can be a resistance wire; current passing through the resistance wire generates Joule heat. The hollow sleeve can directly contact the coating, and the heat generated by the heating rod core can be conducted to the coating to be heated through the hollow sleeve, effectively preventing the high-temperature heating rod core from directly contacting the coating and causing carbonization and deterioration. Furthermore, after heating is complete, the heating rod 1 can be removed from the coating; only the hollow sleeve needs to be cleaned, effectively protecting the heating rod core.
[0036] To facilitate disassembly and assembly, the hollow sleeve can form a detachable connection with the flange connection hole 201, for example, through threaded connection, snap-fit connection, modular interface docking, magnetic connection, pin connection, etc., which are not limited in this application.
[0037] In an optional or preferred embodiment, refer to Figure 1The lifting and adjusting mechanism includes a guide rod 3 arranged vertically and a sliding member 4 that slides with the guide rod 3. The fixed flange 2 is connected to the sliding member 4. Thus, when the sliding member 4 is at the high point of the guide rod 3, the sliding member 4 is released, and the heating device can move downward under its own weight. In other words, when there is paint to be heated below the heating device, multiple heating rods 1 can quickly insert into the paint under their own weight, without the need for manual intervention or additional drive devices to apply downward pressure to the heating device, thereby achieving the descent of multiple heating rods 1.
[0038] In this embodiment, a linear bearing can be used as the sliding element 4. The linear bearing has low damping and high smoothness, which can improve the rapid sinking speed of the heating rod 1. The linear bearing is a sliding component well known to those skilled in the art and is not part of the core improvement of this application. Therefore, its specific structure and working principle will not be described in detail here.
[0039] In an optional or preferred embodiment, refer to Figure 1 The lifting and adjusting mechanism also includes a support arm 5 arranged laterally, and the fixed flange 2 is fixedly connected to the sliding member 4 through the support arm 5. Specifically, as shown in the figure... Figure 1 As shown, the top of the fixed flange 2 is also provided with an intermediate flange, and the fixed flange 2 is fixedly connected to the support arm 5 through the intermediate flange. The support arm 5 is arranged laterally, with one end connected to the fixed flange 2 and the other end connected to the sliding member 4, so that the heating device can be freely raised and lowered along the guide rod 3, and each heating rod 1 maintains a certain distance from the guide rod 3, so that they will not interfere with each other. At the same time, under the support of the support arm 5, it can be ensured that all heating rods 1 can be inserted into the container containing the coating to be heated, without interfering with the container wall.
[0040] In an optional or preferred embodiment, refer to Figure 1 The fixed flange 2 is also provided with a probe connection hole. The heating device also includes a temperature probe 6, which is inserted into the probe connection hole. The temperature probe 6 can move up and down synchronously with the heating rod 1. When inserted into the paint, it can accurately measure the real-time temperature of the paint, which is convenient for controlling the heating temperature and constant temperature control, so that the paint can maintain the preset temperature.
[0041] Optionally, the temperature probe 6 is inserted into the center of the fixed flange 2, thereby measuring the real-time temperature at the center of the coating and ensuring the accuracy of the temperature measurement.
[0042] In an optional or preferred embodiment, the hot-melt equipment includes a movable base 7, on which a lifting and adjusting mechanism is disposed. Specifically, the bottom of the base 7 is provided with omnidirectional casters 701 to facilitate the relocation of the hot-melt equipment during construction and use. In addition, the top of the base 7 can form a platform for placing containers containing the coating to be heated.
[0043] In an optional or preferred embodiment, the hot-melt equipment further includes a control box 8, which is equipped with a controller for controlling the start and stop of the heating device. Both the control box 8 and the heating device are mounted on a lifting and adjusting mechanism to achieve synchronous lifting. Furthermore, the controller can also be connected to a temperature probe 6 for constant temperature control.
