Description

Technical Field

[0001] This utility model relates to the field of hot-melt edge-locking technology for steel plates, specifically to a hot-melt locking machine for edge-locking of profiled steel plates. Background Technology

[0002] Currently, the combined application of profiled steel sheets and flexible waterproof membranes (such as TPO, PVC, etc.) is becoming increasingly widespread, but the existing technologies for combining profiled steel sheets and flexible waterproof membranes still have the following problems:

[0003] In the existing technology, when combining profiled steel sheets with flexible waterproof membranes, the profiled steel sheets must first be fixed by a seam-locking machine, and then the waterproof membrane at the joint of the steel sheets must be manually hot-melted. That is, two processes are used to combine them. However, the separation of these two processes will lead to a long construction period, high labor costs, and the hot-melt quality depends on the worker's experience, which can easily result in missed welds or weak welds.

[0004] In addition, when combining profiled steel sheets with flexible waterproof membranes in existing technologies, exposed nails are used for fixing. However, with this fixing method, the nail holes are prone to deformation due to thermal expansion and contraction, which can lead to cracking of the waterproof layer and a decrease in wind resistance. As a result, it is necessary to clamp the waterproof membrane at the locking edge. However, due to changes in the elasticity of the waterproof membrane, it is prone to locking failure and leakage risk after long-term use, making construction difficult and quality control challenging. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of the existing technology by providing a hot-melt sealing machine for profiled steel sheet edge sealing, so as to simplify the operation steps when combining steel sheet with flexible waterproof membrane.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a hot-melting machine for locking the edge of profiled steel sheets, comprising: a hot-melting machine body, a heating mechanism, and a pressing mechanism;

[0008] The forming mechanism is rotatably mounted at the bottom of the fusion machine body, and the heating mechanism is located inside the fusion machine body and partially extends to the bottom of the fusion machine body;

[0009] The forming mechanism includes at least one set of symmetrically spaced active forming rollers and passive forming rollers, wherein a forming groove for forming steel sheets is formed between each set of active forming rollers and passive forming rollers, and the forming grooves between each pair of adjacent sets are on the same straight line. The heating mechanism is disposed on the body of the hot-melting machine and located between two adjacent sets of active forming rollers. The heating mechanism has a heating position and a non-heating position. When the heating mechanism is in the heating position, the heating mechanism contacts the steel sheet in the forming groove and is used to heat-melt the waterproof membrane on the steel sheet. When the heating mechanism is in the non-heating position, the heating mechanism does not contact the steel sheet in the forming groove.

[0010] In some embodiments, a transmission mechanism is further included, comprising a motor, a main transmission gear, a secondary transmission gear, a worm gear, a turbine gear, and a transmission shaft. The motor is disposed on the body of the fusion machine, and its motor shaft is fixedly connected to the main transmission gear. The main transmission gear meshes with the secondary transmission gear. The secondary transmission gear is disposed on the worm gear and is used to rotate together with the motor shaft of the motor. The transmission shaft is disposed on the body of the fusion machine, one end of which is fixedly connected to the turbine gear, and the other end is fixedly connected to the active forming roller. Each active forming roller is provided with a corresponding turbine gear and transmission shaft. The turbine gear meshes with the worm gear and rotates with the worm gear to drive the active forming roller to rotate.

[0011] In some embodiments, the transmission mechanism further includes a bearing, which is sleeved on the transmission shaft, wherein the outer ring of the bearing is fixedly connected to the body of the fusion machine, and the inner ring of the bearing is interference-fitted with the transmission shaft.

[0012] In some embodiments, a support wheel is also included, which is rotatably disposed at the bottom of the fusion machine body.

[0013] In some embodiments, the heating mechanism includes an electromagnetic push rod, a connecting rod, and a heating part. The electromagnetic push rod is disposed on the body of the fusion machine. The connecting rod is rotatably connected to the drive rod of the electromagnetic push rod. The heating part is disposed at the end of the connecting rod away from the electromagnetic push rod. The electromagnetic push rod is used for switching between the heating position and the non-heating position of the heating mechanism.

[0014] In some embodiments, a clamping lever is further included, which is driven on one side of the fusion machine body.

[0015] In some embodiments, the active forming roller has a groove that matches the edge locking of the steel plate.

[0016] In some embodiments, a power supply component is further included, which is electrically connected to the heating mechanism and the transmission mechanism respectively, and is used to provide power support to the heating mechanism and the transmission mechanism.

[0017] In some embodiments, a temperature control component is further included, which is connected to the heating mechanism and is used to regulate the temperature of the heating element in the heating mechanism.

[0018] Furthermore, the beneficial effects of this utility model are as follows:

[0019] This invention integrates pressing and heating into a single unit by setting up a locking and fusion machine body with both pressing and heating mechanisms. This allows for simultaneous edge locking and hot-melt welding, reducing process changeover time. Specifically, this invention uses symmetrically distributed active and passive pressing rollers to form continuous pressing grooves, ensuring the straightness and accuracy of the steel plate edge locking. Simultaneously, the heating mechanism, driven by an electromagnetic pusher, precisely contacts the waterproof membrane at the steel plate joint, achieving instantaneous hot-melt welding. This avoids manual intervention and process changeover time in traditional step-by-step operations. Furthermore, the high torque output characteristics of the worm gear transmission system ensure a tight fit between the steel plates during edge locking, effectively resisting deformation caused by wind force and thermal expansion and contraction. The heating mechanism also uses an electromagnetic pusher to control station switching, precisely contacting the steel plate and the hot-melt waterproof membrane, avoiding energy loss in non-heated states and ensuring consistent welding quality. This further makes the connection between the steel plate and the flexible waterproof membrane more efficient and reliable. Attached Figure Description

Therefore, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of this utility model, unless otherwise stated, "multiple" means two or more.

[0025] like Figures 1-3 As shown, this utility model embodiment provides a hot-melting machine for locking the edge of profiled steel sheets, including: a hot-melting machine body 1, a heating mechanism, and a pressing mechanism;

[0026] The forming mechanism is rotatably located at the bottom of the fusion machine body 1, and the heating mechanism is located inside the fusion machine body 1 and partially protrudes to the bottom of the fusion machine body 1;

[0027] The forming mechanism includes at least one set of symmetrically spaced active forming rollers 2 and passive forming rollers 16. Each set of active forming rollers 2 and passive forming rollers 16 forms a forming groove for forming the steel sheet 4, and the forming grooves between any two adjacent sets are on the same straight line. A heating mechanism is located on the fusion machine body 1 between two adjacent sets of active forming rollers 2. The heating mechanism has a heating position and a non-heating position. When the heating mechanism is in the heating position, it contacts the steel sheet 4 in the forming groove and is used to heat-melt the waterproof membrane on the steel sheet 4. When the heating mechanism is in the non-heating position... During this process, the heating mechanism does not contact the steel plate 4 in the forming groove. In the above structure, multiple sets of active forming rollers 2 and passive forming rollers 16 are symmetrically arranged at the bottom of the locking and melting machine body 1. A forming groove is formed between each set of active forming rollers 2 and passive forming rollers 16, and multiple sets of active forming rollers 2 and passive forming rollers 16 form a continuous forming groove to ensure the straightness of the steel plate 4 locking edge. In the above process, the active forming rollers 2 are used to press the flexible waterproof membrane and the steel plate 4 together, while the passive forming rollers 16 are used to guide the forming of the steel plate 4 and prevent the steel plate 4 from shifting.

[0028] It is worth noting that the passive forming roller 16 in this utility model is directly rotatably mounted on the body 1 of the fusion machine and does not have an active rotation function; it only serves as an auxiliary guide.

[0029] Furthermore, specifically, this embodiment also includes a transmission mechanism, which comprises a motor 9, a main transmission gear 10, a secondary transmission gear 11, a worm gear 12, a turbine gear 13, and a transmission shaft 6. The motor 9 is mounted on the body 1 of the fusion machine, and its shaft is fixedly connected to the main transmission gear 10. The main transmission gear 10 meshes with the secondary transmission gear 11. The secondary transmission gear 11 is mounted on the worm gear 12 and is used to rotate together with the shaft of the motor 9. The transmission shaft 6 is mounted on the body 1 of the fusion machine, with one end fixedly connected to the turbine gear 13 and the other end fixedly connected to the active forming roller 2. Each active forming roller 2 is correspondingly provided with a turbine gear 13. The transmission worm gear 13 meshes with the transmission worm 12 and follows the rotation of the transmission worm 12 to drive the active forming roller 2 to rotate. In the above structure, a worm gear transmission system is adopted. The motor 9 drives the transmission secondary gear 11 to rotate through the transmission main gear 10. The transmission secondary gear 11 then drives the transmission worm 12 to rotate. The transmission worm 12 is rotatably mounted on the body 1 of the sealing machine. While the transmission worm 12 is rotating, it drives the transmission shaft 6 to rotate through the transmission worm gear 13, thereby driving the active forming roller 2 to rotate. In addition, the worm gear transmission system can provide high torque and low speed drive to ensure that the active forming roller 2 rotates smoothly and avoids misalignment of the steel plate 4 edge locking.

[0030] In one possible implementation, the transmission mechanism further includes a bearing 15, which is sleeved on the transmission shaft 6. The outer ring of the bearing 15 is fixedly connected to the body 1 of the fusion machine, and the inner ring of the bearing 15 is interference-fitted with the transmission shaft 6. In the above structure, the bearing 15 is sleeved on the transmission shaft 6, the inner ring is interference-fitted to reduce friction loss, and the outer ring is fixed to the body 1 of the fusion machine to ensure transmission stability.

[0031] One possible implementation method also includes a support wheel 5, which is rotatably mounted on the bottom of the locking and fusion machine body 1. During construction, the equipment moves along the joint of the steel plate 4 via the support wheel 5. While completing the locking, the heating part 3 heats the membrane at the contact station to form a continuous seamless waterproof layer. This also enhances the stability of the equipment movement and adapts to complex construction environments.

[0032] In one possible implementation, the heating mechanism includes an electromagnetic push rod 7, a connecting rod 8, and a heating part 3. The electromagnetic push rod 7 is disposed on the body 1 of the melting machine, and the connecting rod 8 is rotatably connected to the drive rod of the electromagnetic push rod 7. The heating part 3 is disposed at the end of the connecting rod 8 away from the electromagnetic push rod 7. The electromagnetic push rod 7 is used to switch between the heating position and the non-heating position of the heating mechanism. In the above structure, the heating part 3 in the heating mechanism of this utility model is located between adjacent active forming rollers 2. The electromagnetic push rod 7 drives the heating part 3 to switch between the heating position and the non-heating position through the connecting rod 8. In the heating position, the heating part 3 contacts the steel plate 4, and in the non-heating position, the heating part 3 is detached from the steel plate 4. The purpose of this design is to ensure uniform melting while saving energy.

[0033] It is worth noting that the heating part 3 in this utility model is one of ceramic heating elements, induction heating coils, hot air nozzles, etc. This application does not make specific limitations on it, and those skilled in the art can flexibly select and match according to construction needs. This utility model also intends to include these modifications and variations.

[0034] One possible implementation includes a clamping lever 14, which is driven on one side of the locking and fusion machine body 1 to facilitate manual operation of the device in this utility model.

[0035] In one possible implementation, the active forming roller 2 has a groove that matches the locking edge of the steel plate 4 to enhance the locking force and wind resistance.

[0036] One possible implementation also includes a power supply component and a temperature control component. The power supply component is electrically connected to the heating mechanism and the transmission mechanism respectively, and is used to provide power support to the heating mechanism and the transmission mechanism. The temperature control component is connected to the heating mechanism and is used to regulate the temperature of the heating part 3 in the heating mechanism. The power supply component provides integrated power supply, simplifies equipment wiring, and improves safety. At the same time, the temperature control component realizes dynamic temperature adjustment to avoid overheating or insufficient melting of the roll material.

[0037] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
