Description

Technical Field

[0001] This utility model relates to the field of waterproof membrane processing technology, specifically a hot pressing device for self-adhesive waterproof membrane. Background Technology

[0002] Self-adhesive waterproof membranes are widely used in building waterproofing construction, underground engineering, and roof waterproofing. During construction, the membrane is usually bonded to the substrate by hot pressing or rolling to ensure the overall sealing and durability of the waterproof layer.

[0003] In existing technologies, the hot-pressing construction of roll materials mainly adopts the following two methods: This method typically involves heating the surface of the rolled material using a hot air gun or open flame, followed by rolling with a manual roller. While the equipment is simple, it suffers from low construction efficiency, uneven heating, and unstable compaction, easily leading to localized poor adhesion or air bubble defects.

[0004] Some mechanical hot pressing devices use a single-axis linear pressure roller structure, which heats the rolled material through parallel heating plates or infrared heating elements, and then the pressure roller completes the compaction. This type of device improves efficiency to a certain extent, but it has the following drawbacks: the contact area between the pressure roller and the rolled material is limited, making it impossible to achieve multi-point rolling in continuous motion, resulting in insufficient compaction strength and bonding quality; The heating method is localized and concentrated, and the heat is not evenly distributed in the width of the roll material, which can easily lead to local overheating or poor adhesion. Without trajectory optimization design, the pressure rollers usually move along a straight line or fixed path, which cannot simulate the continuous meshing trajectory of a rotor engine, thus limiting the compaction effect.

[0005] In addition, most existing hot pressing equipment has not optimized the heat transfer method. In some devices, the heating plate does not make sufficient contact with the roller surface or the heat transfer is delayed, which makes the temperature of the roll material uneven during the hot pressing process. This can easily cause local curling, bubbles or delamination, affecting the construction quality and durability.

[0006] In view of this, this paper studies and improves upon the existing problems, and provides a self-adhesive waterproof membrane hot pressing device to solve the current problems. The aim is to solve the problems and improve the practical value through this technology. Utility Model Content

[0007] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0008] Therefore, the technical solution adopted by this utility model is as follows: a self-adhesive waterproof membrane hot pressing device, comprising: a fixed base, a rotating shaft, a press bed, and several roller pressing assemblies. The fixed base is disposed on both sides of the press bed, and a shaft frame is fixedly installed on its surface. The rotating shaft is rotatably mounted on the surface of the shaft frame. Several eccentric shaft portions are arranged on the surface of the rotating shaft, and a corresponding press bed is sleeved on each eccentric shaft portion, forming a structure that can realize eccentric revolution. The roller pressing assembly consists of rolling blocks and pressure rollers arranged at each corner, and continuous rolling is achieved on the surface of the press bed through the eccentric drive of the rotating shaft. The surface of the press bed is provided with a roller pressing curved surface, and an electric heating rod and a liquid guiding cavity are provided inside for heating the membrane and uniform heat conduction, so as to realize the hot pressing bonding function.

[0009] In a preferred embodiment, this invention can be further configured as follows: a fixed base supports the rotating shaft via a shaft bracket, enabling the shaft to rotate stably. Several eccentric portions on the surface of the rotating shaft are connected to a press to form an eccentric drive mechanism. The roller pressing assembly includes rolling blocks and pressure rollers arranged at each corner. The pressure rollers can continuously roll and compact along the roller pressing surface of the press under the eccentric revolution drive of the rotating shaft. An electric heating rod and a liquid guiding cavity are provided inside the press, enabling the heating and softening of the roll material during the compaction process, achieving the functions of hot pressing and imprinting of the roll material.

[0010] Specifically, this structure can simultaneously achieve hot pressing and rolling compaction during the roll material laying process, improving the adhesion of the roll material and construction efficiency.

[0011] In a preferred example, the two ends of the rotating shaft pass through the two side shaft brackets and are connected to an external drive assembly. The shaft is driven by a motor or gear to achieve continuous self-rotation, thereby driving the roller pressing assembly to perform eccentric revolution.

[0012] Specifically, this structure enables continuous and stable driving, allowing the pressure roller to roll smoothly along the surface of the roll material, ensuring uniform hot pressing.

[0013] In a preferred example, the cross section of the rolling block adopts a Reuleaux triangle design, and the roller pressing surface of the press is an internal meshing annular cavity surface structure that matches the rolling trajectory of the Reuleaux triangle, so that the pressure roller is always in close contact with the roller pressing surface during the revolution.

[0014] Specifically, this design can create three continuous contact points, improving the compaction strength and uniformity of the roll material during hot pressing.

[0015] In a preferred example, the surface of the rotating shaft is provided with four off-axis portions, which are evenly arranged along the axial line, and the included angle between the eccentric directions of adjacent off-axis portions is 90 degrees.

[0016] Specifically, by using multiple sets of roller pressing components in sequence, continuous multi-point hot pressing of the roll material can be achieved, significantly improving processing efficiency.

[0017] In a preferred example, the fixed base surface is provided with a fixed guide tooth coaxial with the rotating shaft, and the two sides of the rolling block are provided with ring gears. The fixed guide tooth and the ring gear mesh with each other to guide the eccentric revolution of the rolling block.

[0018] Specifically, it can ensure the stability of the eccentric rolling trajectory, prevent the pressure roller from jumping during operation, and improve the compaction quality and equipment life.

[0019] In a preferred example, the end of the electric heating rod is electrically connected to a constant temperature control module, and a heat conduction fluid is added to the liquid guiding cavity to uniformly conduct the heat of the electric heating rod to the surface of the rolled curved surface.

[0020] Specifically, the structure enables constant temperature control and uniform heat distribution, preventing localized overheating or uneven compaction of the roll material.

[0021] In a preferred example, the pressure roller is a hard rubber roller structure with an embossing layer on its surface, which can be used to form text or patterns.

[0022] Specifically, marking and imprinting can be completed simultaneously during the hot pressing process of the roll material, improving the product's functionality and decorative effect.

[0023] In summary, this utility model achieves efficient hot pressing and compaction of the roll material by continuously rolling the roll material through the eccentric drive of the rotating shaft and the combination of internal heating and heat transfer fluid circulation in the press. The Reuleaux triangle rolling block and the annular cavity curved surface design improve contact stability and compaction strength. Equipped with guiding engagement and imprinting functions, it achieves high efficiency and functionality in the construction process.

[0024] The beneficial effects achieved by this utility model are as follows: 1. In this utility model, the roller pressing assembly is driven to rotate eccentrically by the off-axis part on the rotating shaft, and the meshing trajectory of the Reuleaux triangular rotor and the chamber in the rotor engine is simulated by the rolling block and the roller pressing surface, so as to realize the continuous high-strength rolling of the self-adhesive waterproof membrane by the pressure roller, effectively improving the hot pressing bonding efficiency and compaction quality.

[0025] 2. In this utility model, an electric heating rod and a liquid guiding cavity are arranged inside the press, which can achieve uniform heat diffusion to the roller surface through the heat conduction liquid, and maintain a stable working temperature with the constant temperature control module to ensure that the roll material is heated evenly during the hot pressing process and avoid local overheating or poor compaction.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0029] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0030] The following describes, with reference to the accompanying drawings, some embodiments of a self-adhesive waterproof membrane hot-pressing device provided by this utility model.

[0031] Combination Figures 1-5 As shown, the present invention provides a self-adhesive waterproof membrane hot pressing device, which includes a fixed base 100, a rotating shaft 200, a press 300 and several roller pressing components 400.

[0032] The fixed base 100 is fixedly installed on both sides of the press 300 to provide stable support for the entire device. The fixed base 100 has a shaft bracket 110 fixedly installed on its surface. The rotating shaft 200 is rotatably installed through the shaft brackets 110 on both sides, thereby achieving stable rotation under the action of the drive assembly.

[0033] The surface of the rotating shaft 200 is provided with several off-axis portions 210 along its axial direction. Each press 300 is sleeved on the surface of the corresponding off-axis portion 210 through a central hole or a sleeve structure to realize the eccentric drive function.

[0034] The roll forming assembly 400 consists of a rolling block 410 and pressure rollers 420. The rolling block 410 has a Reuleaux triangle cross-section, and pressure rollers 420 are fixedly installed at each vertex of the triangle. When the rotating shaft 200 rotates and drives the rolling block 410 to revolve through the off-axis part 210, each pressure roller 420 will roll along the rolling surface 301 on the surface of the press 300 to achieve continuous hot pressing of the roll material.

[0035] The press 300 has a roller pressing surface 301 on its surface. Its shape is an inner meshing annular cavity surface that matches the rolling trajectory of the Reuleaux triangle. It can simulate the meshing motion of the rotor and the chamber of a rotary engine, ensuring that the press roller 420 is always in contact with the roller pressing surface 301 during the entire revolution, thereby improving the hot pressing effect.

[0036] The press 300 is equipped with an electric heating rod 310 and a liquid guiding cavity 320. The electric heating rod 310 is used to provide a heat source, and the liquid guiding cavity 320 is filled with heat transfer fluid to evenly conduct the heat generated by the electric heating rod 310 to the surface of the roll-pressed curved surface 301, thereby realizing the continuous heating and softening of the roll material.

[0037] When the device is working, the external drive assembly drives the rotating shaft 200 to rotate via a coupling or gear drive device connected to both ends of the rotating shaft 200. The off-axis portion 210 on the surface of the rotating shaft 200 drives the roller pressing assembly 400 to achieve eccentric revolution, the rolling block 410 rolls on the trajectory within the roller pressing surface 301, and the pressure roller 420 continuously rolls on the surface of the roll material.

[0038] To achieve stable eccentric rolling, a fixed guide tooth 120 is coaxially mounted on the surface of the fixed seat 100, and ring gears 411 are provided on both sides of the rolling block 410. Through the meshing action of the fixed guide tooth 120 and the ring gears 411, the controlled eccentric movement of the rolling block 410 is realized, so that the trajectory of the pressure roller 420 is stable and it fits precisely with the roller pressing surface 301.

[0039] In this embodiment, the electric heating rod 310 inside the press 300 is energized and its temperature is controlled by a constant temperature control module. The heat is conducted to the roller pressing surface 301 through the liquid guiding cavity 320, achieving uniform heating of the roll material. During the eccentric rolling process, the pressure roller 420 can compact and bond the heated and softened self-adhesive waterproof roll material, completing the hot pressing molding.

[0040] In this embodiment, the cross-section of the rolling block 410 is designed as a Reuleaux triangle, with pressure rollers 420 arranged at each vertex of the triangle, enabling continuous contact at three points during the revolution and improving the compaction effect of the roll material. The roller pressing surface 301 of the press 300 is an internally meshing annular cavity curved surface structure that matches the rolling trajectory of the Reuleaux triangle, ensuring that the pressure rollers 420 remain in contact with the roll material surface throughout the revolution of the rolling block 410.

[0041] The surface of the rotating shaft 200 is provided with four eccentric portions 210 evenly arranged along the axial direction. The included angle between the eccentric directions of adjacent eccentric portions 210 is 90 degrees, which can realize the continuous hot pressing of the roll material by multiple sets of roller pressing components 400 in sequence, thereby improving processing efficiency.

[0042] The fixed guide tooth 120 works in conjunction with the ring gear 411 to ensure the stability of the eccentric rolling trajectory of the rolling block 410 and avoid uneven compaction of the roll material due to unstable eccentric movement.

[0043] In this embodiment, the two ends of the electric heating rod 310 are electrically connected to the constant temperature control module, and different temperature curves can be set according to the characteristics of the roll material to achieve stable constant temperature heating; a highly thermally conductive liquid is injected into the liquid guiding cavity 320 to improve the heat conduction efficiency and ensure that the temperature distribution of the roll-pressed curved surface 301 is uniform.

[0044] In this embodiment, the pressure roller 420 adopts a hard rubber roller structure with an embossing layer on its surface, which can emboss text, patterns or anti-counterfeiting marks while the roll material is being hot-pressed, thereby increasing the functionality of the roll material.

[0045] Working principle and usage process of this utility model: During the conveying motion of the rolled material through the roller pressing surface 301, when the external drive assembly is activated, the drive shaft 200 rotates along its axis; several eccentric portions 210 arranged on the surface of the shaft 200 drive the sleeved roller pressing assembly 400 to perform eccentric revolution; the roller pressing assembly 400 includes a rolling block 410 and pressure rollers 420 arranged at each corner thereon, the rolling block 410 moves along the roller pressing surface 301 of the press 300 along a trajectory similar to the rolling of a rotor engine under the eccentric drive of the shaft 200; the pressure rollers 420 move along the rolling block 410... During the revolution, the roller continuously slides in contact with the roller pressing surface 301, achieving continuous rolling of the roll material surface. At the same time, the electric heating rod 310 inside the press 300 is energized and heated, and the heat is evenly transferred to the surface of the roller pressing surface 301 through the heat conduction liquid in the liquid guiding cavity 320, so as to perform constant temperature softening or heat melting treatment on the roll material. The meshing action of the fixed guide tooth 120 and the ring gear 411 can guide the rolling block 410 to achieve controlled eccentric rolling, ensuring the fit between the pressure roller 420 and the roller pressing surface 301, and improving the hot pressing efficiency and stability.
