Description

Technical Field

[0001] This utility model relates to the field of concrete product processing technology, specifically to a surface grinding device for concrete products that can prevent dust generation. Background Technology

[0002] Concrete products are industrial products made from concrete or mortar as basic materials. Blocks, such as aerated concrete blocks, use sand, cement, and foaming agents as raw materials. They are lightweight, heat-insulating, and sound-insulating, and are often used in building walls. There are also solid concrete bricks and porous concrete bricks, which can be used for wall construction. The production process generally includes raw material preparation, mixing, molding, and curing. The quality of raw materials must be strictly controlled. During mixing, the water-cement ratio, mixing time, and speed must be controlled. Molding methods include vibration molding, pressing molding, and centrifugal molding. Curing methods include natural curing, steam curing, and autoclaving to ensure the strength and durability of concrete products.

[0003] After the concrete products are formed, the surface is relatively rough and needs to be polished. In the existing method of polishing concrete products, the sides of the product are usually fixed by clamps. However, when the sides of the product are curved, ordinary clamps cannot effectively limit the curved surface, which causes the product to shift and slide during polishing, affecting the processing quality of the product. Utility Model Content

[0004] The purpose of this utility model is to provide a surface grinding device for concrete products that can prevent dust generation, in order to solve the problem mentioned in the background art that when the side of the product is curved, ordinary clamps cannot effectively limit the curved surface, which causes the product to shift and slide during grinding, affecting the processing quality of the product.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust-proof surface grinding device for concrete products, comprising a working shell, a maintenance door panel installed on its front surface, a dust removal box fixedly connected to the lower end of the working shell, and a collection box fixedly connected to the lower end of the dust removal box, a grinding machine body installed on the top surface of the cavity of the working shell, a support worktable fixedly connected to the bottom surface of the cavity of the working shell, a guide groove opened on the upper surface of the dust removal box, and an air pump fixedly connected to the lower rear surface of the dust removal box. The machine has air intake mounting blocks installed through both sides of the working shell. An air intake pipe is fixedly connected to the outer surface of the air intake mounting block, and a dust suppression nozzle is fixedly connected to the inner surface of the air intake mounting block. An electric push rod is fixedly connected to both sides of the working shell. The output end of the electric push rod penetrates through the surface of the working shell and is fixedly connected to a support slider. Two positioning slide rods are provided on the surface of the support slider, and one end of each positioning slide rod is fixedly connected to a main limiting plate. A linkage mechanism is provided on the surface of the main limiting plate.

[0006] Preferably, the working housing and the maintenance door panel are rotatably connected, and the bottom surfaces on both sides of the working housing are provided with openings, and the openings of the working housing are connected to the guide slots.

[0007] The above technical solution, with its rotating connection design, allows the maintenance door panel to open and close flexibly. Workers can easily access the internal space of the equipment without disassembling the door panel, facilitating routine inspection, cleaning, or repair of core components such as the grinding machine body and support worktable inside the working shell. This reduces equipment downtime for maintenance and improves overall processing efficiency.

[0008] Preferably, the guide slot is Y-shaped and connected to the air pump, and a filter screen is provided between the guide slot and the air pump. The guide slot is also connected to the collection box.

[0009] Using the above technical solution, the Y-shaped guide slot can simultaneously collect dust from the openings on both sides of the working shell, expanding the dust collection range and avoiding the problem of incomplete collection from a single channel. Combined with the negative pressure adsorption effect of the air pump, it can quickly suck the dust generated during grinding into the slot, improving the dust collection efficiency.

[0010] Preferably, the air intake pipe is connected to the dust suppression nozzle, and the dust suppression nozzle is inclined downward. The support slider is slidably connected to the working housing, and the support slider is slidably connected to the positioning slider. A spring is connected between the support slider and the positioning slider.

[0011] Using the above technical solution, the air intake pipe delivers high-pressure gas or water mist to the dust suppression nozzle. The downward-sloping nozzle design allows the airflow to act precisely on the grinding area, directly suppressing the newly generated dust and preventing the dust from spreading to the upper space of the working shell. This, together with the adsorption effect of the air pump, forms a dual dust suppression mechanism of "pressure and suction", further improving the dust prevention effect.

[0012] Preferably, the linkage mechanism includes side fixing frames, two side fixing frames are fixed on both sides of the support slider, a linkage rotating arm is installed on the surface of the side fixing frame, and side limiting plates are provided on both sides of the main limiting plate.

[0013] By adopting the above technical solution, a side limiting plate is added on the basis of the main limiting plate to form a multi-directional fixing mode of "main limiting + side limiting". It can not only limit the front of the workpiece, but also restrict the lateral displacement of the workpiece from both sides. This solves the problem that the traditional single clamping plate can only fix flat workpieces and cannot constrain curved or irregular workpieces, thus improving the adaptability of the equipment to concrete products of different shapes.

[0014] Preferably, the side fixing frame is slidably connected to one end of the linkage rotating arm, and a spring is connected between the side fixing frame and the linkage rotating arm, while the other end of the linkage rotating arm is rotatably connected to the side limiting plate.

[0015] By adopting the above technical solution, the elastic properties of the spring can play a buffering role when the side limiting plate contacts the workpiece, avoiding rigid collisions that could damage the workpiece surface or deform the linkage mechanism. When there are slight deviations in the workpiece size, the spring's extension and contraction can compensate for the deviation, ensuring that the limiting effect is not affected and improving the equipment's compatibility with workpiece size tolerances.

[0016] Preferably, the side limiting plate and the main limiting plate are rotatably connected, and the surfaces of the side limiting plate and the main limiting plate are provided with anti-slip rubber strips, and the surface of the side limiting plate is provided with an arc-shaped groove.

[0017] By adopting the above technical solution, the anti-slip rubber strip increases the friction between the limiting plate and the workpiece surface, further preventing the workpiece from shifting due to vibration during the grinding process. The rubber strip is made of soft material, which can prevent the metal limiting plate from directly contacting the workpiece surface and causing scratches or indentations. While ensuring the fixing effect, it protects the integrity of the workpiece's appearance.

[0018] Compared with the prior art, the beneficial effects of this utility model are: This surface grinding equipment for dust-proof concrete products: 1. By spraying air downwards at an angle through the dust suppression nozzle, the dust generated in the grinding area can be directly suppressed, preventing the dust from spreading. In conjunction with the air pump, the dust is adsorbed through the Y-shaped guide groove, and then collected into the collection box after being filtered by the filter screen. This forms a complete dust prevention process of "suppression-adsorption-filtration-collection", which reduces environmental pollution and avoids dust wear on the internal components of the equipment. 2. The main limiting plate works in conjunction with the two rotatable side limiting plates, and the side limiting plates have arc-shaped grooves on their surfaces. They can automatically fit the shape of concrete products, especially those with arc-shaped sides. At the same time, the springs between the supporting slider and the positioning slider, and the springs between the side fixing frame and the linkage rotating arm provide buffering and elastic force, ensuring that the workpiece is firmly fixed and not squeezed or damaged, thus solving the problem that traditional clamps cannot effectively limit arc-shaped workpieces. 3. The working shell and maintenance door are rotatably connected, which makes it easy for staff to quickly open the equipment for component inspection, cleaning and maintenance. The support slider is slidably connected to the working shell, and the position of the limit structure can be adjusted by electric push rod to adapt to workpieces of different widths, reduce equipment adjustment time and improve overall processing efficiency.

[0022] Please see Figure 1-6This utility model provides a technical solution: a surface grinding device for concrete products that can prevent dust generation, including a working shell 1, a maintenance door panel 2, a dust removal box 3, a collection box 4, a grinding machine body 5, a support workbench 6, a guide slot 7, an air pump 8, an air inlet mounting block 9, an air inlet pipe 10, a dust suppression nozzle 11, an electric push rod 12, a support slider 13, a positioning slider 14, a main limiting plate 15, a side fixing frame 16, a linkage rotating arm 17, and a side limiting plate 18. The working shell 1 has a maintenance door panel 2 installed on its front surface. The lower end of the working shell 1 is fixedly connected to the dust removal box 3, and the lower end of the dust removal box 3 is fixed to the collection box 4. The top of the cavity of the working shell 1... The surface is equipped with a grinding machine body 5. A support worktable 6 is fixedly connected to the bottom surface of the cavity of the working shell 1. A guide groove 7 is opened on the upper surface of the impurity removal box 3.

Openings are provided on the bottom surfaces of both sides of the working shell 1, and the openings of the working shell 1 are connected to the guide groove 7. When the electric push rod 12 is activated, its output end pushes the support slider 13 to slide along the inner wall of the working shell 1, adjusting the distance between the main limiting plate 15 and the workpiece. The support slider 13 and the positioning slide rod 14 slide in cooperation, and the spring between the two provides buffer. When the main limiting plate 15 contacts the workpiece, the spring is compressed to generate elastic force, so that the main limiting plate 15 is tightly attached to the front of the workpiece.

[0023] An air pump 8 is fixedly connected to the lower rear surface of the dust removal box 3. Air inlet mounting blocks 9 are installed through both sides of the working outer shell 1. An air inlet pipe 10 is fixedly connected to the outer surface of the air inlet mounting block 9, and a dust suppression nozzle 11 is fixedly connected to the inner surface of the air inlet mounting block 9. The guide slot 7 is Y-shaped and connected to the air pump 8. A filter screen is installed between the guide slot 7 and the air pump 8. The guide slot 7 is connected to the collection box 4. The air inlet pipe 10 is connected to the dust suppression nozzle 11, which is inclined downwards. The support slider 13 is connected to the working... The outer shell 1 forms a sliding connection, the support slider 13 and the positioning slider 14 form a sliding connection, and a spring connects the support slider 13 and the positioning slider 14. When the main limiting plate 15 contacts the workpiece, the linkage rotating arm 17 on the side fixing frame 16 rotates due to the movement of the support slider 13. The other end of the linkage rotating arm 17 drives the side limiting plate 18 to rotate around the main limiting plate 15. The arc-shaped groove on the surface of the side limiting plate 18 fits against the side of the workpiece, and the spring between the side fixing frame 16 and the linkage rotating arm 17 provides tension to ensure that the side limiting plate 18 stably fits against both sides of the workpiece, thus completing the all-round fixation of the workpiece.

[0024] Electric push rods 12 are fixedly connected to both sides of the working shell 1. The output end of the electric push rod 12 penetrates the surface of the working shell 1 and is fixedly connected to the output end of the electric push rod 12. A support slider 13 is fixedly connected to the output end of the electric push rod 12. Two positioning sliders 14 are provided on the surface of the support slider 13, and a main limiting plate 15 is fixedly connected to one end of the two positioning sliders 14. The linkage mechanism includes side fixing frames 16. Two side fixing frames 16 are fixed on both sides of the support slider 13. A linkage rotating arm 17 is installed on the surface of the side fixing frames 16. Side limiting plates 18 are provided on both sides of the main limiting plate 15. The grinding machine body 5 is started to grind the surface of the concrete product fixed on the support worktable 6. At the same time, gas is delivered to the air inlet mounting block 9 through the air inlet pipe 10 and sprayed downward at an angle through the dust suppression nozzle 11 to the grinding area to suppress the dust that has just been generated and prevent the dust from spreading.

[0025] The main limiting plate 15 is provided with a linkage mechanism. The side fixing frame 16 and one end of the linkage rotating arm 17 are slidably connected, and a spring is connected between the side fixing frame 16 and the linkage rotating arm 17.

The surfaces of the side limiting plate 18 and the main limiting plate 15 are provided with anti-slip rubber strips. The surface of the side limiting plate 18 is provided with an arc-shaped groove. When the vacuum pump 8 is started, a negative pressure is formed in the impurity removal box 3. The dust generated by grinding enters the guide slot 7 through the openings on both sides of the bottom surface of the working shell 1. The Y-shaped guide slot 7 collects the dust and transports it to the filter screen. The filter screen intercepts the dust and prevents the dust from entering the vacuum pump 8. The intercepted dust falls into the collection box 4, realizing the centralized collection of dust.

[0026] Working principle: When using this dust-proof surface grinding equipment for concrete products, the electric push rod 12 pushes the support slider 13 to move. The main limiting plate 15 fits against the front of the workpiece under the cooperation of the positioning slide rod 14 and the spring. The linkage rotating arm 17 drives the side limiting plate 18 to rotate around the main limiting plate 15. The arc-shaped groove automatically fits the side of the workpiece. When the grinding machine body 5 is grinding, the dust suppression nozzle 11 sprays air to suppress dust. The air pump 8 adsorbs dust through the guide slot 7. After being filtered by the filter screen, the dust falls into the collection box 4, which increases the overall practicality.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
