Description

Technical Field

[0001] This utility model relates to the field of expanded perlite insulation board processing technology, and in particular to a grooving device for the surface of expanded perlite insulation board. Background Technology

[0002] Expanded perlite insulation board, as an inorganic insulation material widely used in the field of building energy conservation, uses expanded perlite as the core aggregate, combined with inorganic cementitious materials such as cement and gypsum, as well as additives such as waterproofing agents and reinforcing agents. It is made through processes such as mixing, molding, and curing. With its excellent properties such as light weight (porosity can reach 70%~90%), low thermal conductivity, high temperature resistance, and non-combustibility, it is widely used in thermal insulation projects for building walls and roofs, and is one of the key materials for achieving energy conservation and consumption reduction in buildings.

[0003] However, the existing production process of expanded perlite insulation boards often results in a smooth or unevenly rough surface. This structural defect exposes significant problems in actual construction applications: On the one hand, when the insulation board is directly bonded to the building substrate with adhesive mortar, the smooth or irregularly rough surface limits the effective contact area between the mortar and the board, easily forming a closed air layer at the bonding interface. This leads to insufficient bonding strength and makes it difficult to meet the building structure's requirements for the bonding reliability of the insulation system. After long-term use, under the influence of external factors such as temperature changes and vibration, safety hazards such as hollowing and detachment are likely to occur, seriously affecting the stability and service life of the insulation project. On the other hand, building walls will undergo thermal expansion and contraction deformation due to changes in ambient temperature during service. This deformation will be transmitted to the bonding layer between the insulation board and the wall. The lack of an effective stress dispersion structure between the smooth surface of the insulation board and the mortar bonding layer leads to uneven stress distribution and stress concentration in local areas, which in turn causes cracking of the bonding layer, damages the integrity of the insulation system, reduces the thermal insulation effect, and may even cause a chain of structural safety problems.

[0004] To address the aforementioned technical challenges, a specialized device was developed capable of precisely grooving the surface of expanded perlite insulation boards. By forming regular grooves on the board surface, the bonding interface structure is optimized, improving bonding reliability and stress dispersion capabilities, thereby ensuring the construction quality and long-term service performance of building insulation projects. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a grooving device for the surface of expanded perlite insulation board.

[0006] This utility model is achieved through the following technical solution: A grooving device for expanded perlite insulation board includes a base on which a grooving assembly is mounted. The grooving assembly includes an angle-adjustable deflector seat on one side of the base. A first slide is slidably connected to the deflector seat, a second slide is slidably connected to the first slide, and a motor is slidably connected to the second slide. The output end of the motor is provided with a locking sleeve for mounting a milling cutter. The angle of the motor and the locking sleeve is adjusted by deflecting the deflector seat. Simultaneously, the first slide slides on the deflector seat, and the height of the second slide is adjusted on the first slide to adjust the grooving angle and position.

[0007] Optionally, in one possible implementation, support rods are respectively provided on the top two sides of the base, and a slide is provided at one end of each support rod. Two first electric push rods are slidably connected on the slide, and a pressure plate for positioning the insulation board is provided at the output end of each first electric push rod. A pad is provided at the bottom of the pressure plate, and a second electric push rod for driving the second slide to move up and down is provided at the bottom of the first slide.

[0008] Optionally, in one possible implementation, a third electric push rod is hinged to the bottom of the inner wall of the base. The output end of the third electric push rod is hinged to a first hinge rod. One end of the first hinge rod is hinged to the base, and the other end of the first hinge rod is hinged to a second hinge rod. One end of the second hinge rod extends to the bottom of the deflection seat and is hinged to the deflection seat. The third electric push rod drives the first hinge rod to adjust the angle, which in turn drives the second hinge rod to pull the deflection seat to deflect. A knob is provided at the end of the slide and on the outside of the first electric push rod, respectively, for rotating the knob to make the knob abut against the outside of the slide and the support rod to position the slide and the first electric push rod.

[0009] The technical effects and advantages of this utility model are as follows: This invention uses a grooving component to create regular grooves on the surface of expanded perlite insulation board. Compared to existing smooth or rough and uneven board surfaces, this effectively increases the contact area between the bonding mortar and the board. At the same time, it breaks the conditions for the formation of a closed air layer, allowing the mortar to fully fill the grooves and form a mechanical interlocking structure with the board. This significantly improves the bonding strength and interfacial bonding stability, fundamentally solving the technical problems of insufficient bonding strength and easy hollowing and detachment of traditional insulation boards after long-term use, and ensuring the long-term reliability of building insulation systems.

[0010] Meanwhile, the deflection seat can be deflected by the hinge rod mechanism driven by the third electric push rod, which can realize the precise and automatic adjustment of the grooving angle; the first slide slides horizontally along the deflection seat, the second electric push rod drives the second slide to move up and down, and the motor makes fine adjustments on the second slide, which can flexibly adjust the horizontal position, depth and accuracy of the grooving, and can adapt to the grooving needs of different specifications of insulation boards and different construction scenarios, such as grooves with different inclination angles and different depths. It has strong versatility and wide applicability.

[0011] In addition, the support rod, slide, first electric push rod, pressure plate, and pad at the top of the base form a coordinated positioning mechanism. The positioning distance can be flexibly adjusted according to the size of the insulation board. The elastic pad ensures the insulation board is firmly pressed and avoids damage to the board surface. At the same time, the knob positioning structure ensures the positional stability of the slide and the first electric push rod during operation, effectively preventing component displacement caused by vibration, ensuring the straightness, depth uniformity, and angle accuracy of the grooving channel, and improving the grooving processing quality.

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and preferred embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] In the description of the utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0020] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0021] Example 1: This example discloses a grooving device for the surface of expanded perlite insulation board, which aims to solve the technical problems of existing expanded perlite insulation boards having smooth or uneven surfaces, resulting in limited contact area with the bonding mortar, easy formation of closed air layers, and thus insufficient bonding strength, potential for hollowing and falling off after long-term use, and uneven stress distribution between the insulation board and the mortar bonding layer, which easily leads to cracking.

[0022] Specifically, the expanded perlite insulation board surface grooving device includes a base 1, which serves as the installation foundation for the entire device, providing a stable support platform for all components. A grooving assembly for grooving the insulation board is mounted on the base 1. This grooving assembly includes a deflector seat 2 located on one side of the base 1. The deflector seat 2 is angularly adjustable to the base 1; adjusting the angle of the deflector seat 2 allows subsequent related components to adjust the grooving angle.

[0023] A first slide block 3 is slidably connected to the deflector seat 2. The first slide block 3 can slide horizontally along the length of the deflector seat 2, thereby adjusting the horizontal position of the slot. A second slide block 4 is slidably connected to the first slide block 3. The sliding direction of the second slide block 4 is perpendicular to the sliding direction of the first slide block 3, used to achieve vertical position adjustment. A motor 5 is slidably connected to the second slide block 4. The motor 5 can be finely adjusted along the second slide block 4 to ensure the precise installation position of the milling cutter. A locking sleeve 6 is provided at the output end of the motor 5. The locking sleeve 6 is used to securely install the milling cutter. When the motor 5 is started, it can drive the milling cutter to rotate at high speed to achieve the slotting operation. By adjusting the deflection of the deflector seat 2, the angle of the motor 5 and the locking sleeve 6 can be precisely adjusted to meet the slotting requirements of different tilt angles. At the same time, the sliding of the first slide block 3 on the deflector seat 2 can adjust the horizontal position of the slot, and the height adjustment of the second slide block 4 on the first slide block 3 can adapt to the slotting depth requirements of insulation boards of different thicknesses, ultimately achieving flexible and precise control of the slotting angle and position.

[0024] like Figure 1-3 As shown, support rods 7 are fixedly installed on both sides of the top of the base 1. The support rods 7 are perpendicular to the top surface of the base 1 and are symmetrically distributed. A slide 8 is provided at one end of each support rod 7. Two first electric push rods 9 are slidably connected to the slide 8. The first electric push rods 9 can slide along the length of the slide 8 to adjust the distance between the two first electric push rods 9 according to the size of the insulation board. A pressure plate 10 is fixedly installed at the output end of each first electric push rod 9. The pressure plate 10 has a circular structure and is used to press and position the insulation board. A pad 11 is provided at the bottom of the pressure plate 10. The pad 11 is made of elastic rubber material, which enhances the friction with the surface of the insulation board and improves positioning stability when pressing the insulation board, while also preventing the pressure plate 10 from damaging the surface of the insulation board.

[0025] Example 2: Based on Example 1, this example... Figure 1 , Figure 2 and Figure 4 As shown, a second electric push rod 12 is fixedly installed at the bottom of the first slide block 3. The output end of the second electric push rod 12 is fixedly connected to the second slide block 4. Through the extension and retraction of the second electric push rod 12, the second slide block 4 can be driven to move up and down along the first slide block 3, so as to achieve precise control of the slotting depth. This is more efficient and precise than manual adjustment.

[0026] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, a third electric push rod 13 is hinged to the bottom of the inner wall of the base 1, and a first hinge rod 14 is hinged to the output end of the third electric push rod 13. One end of the first hinge rod 14 is hinged to the inner wall of the base 1, and the other end of the first hinge rod 14 is hinged to a second hinge rod 15. One end of the second hinge rod 15 extends to the bottom of the deflection seat 2 and is hinged to the deflection seat 2. When it is necessary to adjust the angle of the deflection seat 2, the third electric push rod 13 is activated. The extension and retraction movement of the third electric push rod 13 drives the first hinge rod 14 to adjust its angle around its hinge point with the base 1. The change in the angle of the first hinge rod 14 will cause the second hinge rod 15 to move, thereby pulling the deflection seat 2 to deflect around its connection point with the base 1, realizing the automatic adjustment of the slotting angle. The adjustment process is smooth and the angle control is precise.

[0027] like Figure 1 and Figure 3 As shown, knobs are respectively provided at the end of the slide 8 and on the outside of the first electric push rod 9. When the slide 8 is adjusted to a suitable position on the support rod 7 and the first electric push rod 9 is adjusted to the corresponding distance on the slide 8, the knobs are rotated so that the knobs abut against the outside of the slide 8 and the support rod 7. The slide 8 and the first electric push rod 9 are positioned by friction, ensuring that the position of each component remains stable during the grooving operation and avoiding positional displacement due to vibration that affects the grooving quality.

[0028] The specific working principle is as follows: First, based on the dimensions of the expanded perlite insulation board to be grooved, loosen the knob at the end of the slide 8 and adjust the position of the slide 8 on the support rod 7. Then, loosen the knob on the outside of the first electric push rod 9 and adjust the distance between the two first electric push rods 9 on the slide 8 to match the width of the insulation board. After adjustment, tighten the knob to achieve positioning. Place the insulation board to be grooved on the top surface of the base 1, directly below the two pressure plates 10.

[0029] Start the first electric push rod 9. The output end of the first electric push rod 9 extends downward, driving the pressure plate 10 and the pad 11 to move down synchronously until the pad 11 is tightly attached to the surface of the insulation board. Through the coordinated action of the four pressure plates 10, the insulation board is firmly pressed onto the base 1, completing the positioning and fixing of the insulation board and preventing the insulation board from shifting during the grooving process.

[0030] According to the preset grooving angle requirement, the third electric push rod 13 is activated, which drives the first hinge rod 14 to swing. The first hinge rod 14 drives the second hinge rod 15 to pull the deflection seat 2 to the target angle, as shown in Figure 5. The deflection angle is precisely controlled by the extension and retraction of the third electric push rod 13. Subsequently, according to the horizontal position requirement of the grooving, the first slide 3 is pushed to slide along the deflection seat 2 to the corresponding position; the second electric push rod 12 is activated, driving the second slide 4 to move up and down along the first slide 3, adjusting the height of the milling cutter to the preset grooving depth position; finally, the position of the motor 5 on the second slide 4 is finely adjusted to ensure that the mounting center of the milling cutter is aligned with the grooving baseline.

[0031] The appropriate milling cutter is securely installed on the output end of the motor 5 using the locking sleeve 6. The motor 5 is then started, causing the milling cutter to rotate at high speed. At this time, external force pushes the first slide 3 to slide uniformly along the deflection seat 2. During high-speed rotation, the milling cutter contacts the surface of the insulation board, achieving the grooving operation. During the grooving process, the height of the second slide 4 remains constant to ensure a uniform grooving depth; the angle of the deflection seat 2 remains fixed to ensure the grooving angle meets the preset requirements.

[0032] After the grooving operation is completed, turn off motor 5, and the milling cutter stops rotating. Control the output end of the first electric push rod 9 to retract upwards, causing the pressure plate 10 and the pad 11 to detach from the surface of the insulation board, releasing the clamping and positioning of the insulation board. Remove the grooved insulation board from the base 1, completing the entire grooving process.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
