Description

Technical Field

[0001] This utility model relates to the field of tabletop processing technology, and more specifically, to a grinding device for pre-treatment of tabletop membrane pressing. Background Technology

[0002] In the membrane pressing process, the pretreatment of the membrane plate surface is crucial. The flatness and roughness of the membrane plate surface directly affect the quality and appearance of the pressed product. Currently, traditional grinding methods in the membrane pressing pretreatment grinding stage have many drawbacks.

[0003] On the one hand, many existing grinding equipment have a low degree of automation. For example, some small processing plants still use manual hand-held grinding tools, which is not only inefficient but also makes it difficult to guarantee the uniformity of grinding, resulting in inconsistent quality of the plates ground by different workers. Even if some factories have adopted automated grinding equipment, the movement and positioning of the equipment are not precise enough, leading to poor grinding results that cannot meet the production requirements of high-precision membrane pressing products.

[0004] On the other hand, the problem of handling debris generated during the grinding process is also quite prominent. If the debris is not cleaned up in time, it will repeatedly rub against the surface of the grinding table, which not only affects the grinding quality but may also cause wear and tear on the grinding equipment, shortening its service life. Some existing debris cleaning methods, such as simple air blowing or manual sweeping, are not ideal. Air blowing may cause debris to scatter and pollute the working environment, while manual sweeping is inefficient and difficult to clean thoroughly.

[0005] Furthermore, traditional sanding equipment has poor adaptability to workbenches of different thicknesses or materials. When sanding workbenches of different sizes, complex adjustments to the equipment are often required, and sometimes parts may even need to be replaced, which greatly increases production costs and production cycles.

[0006] In summary, existing countertop membrane pretreatment and polishing methods and equipment have shortcomings in polishing efficiency, polishing quality, debris handling, and equipment adaptability. There is an urgent need for a new polishing device that can solve the above problems. Utility Model Content

Detailed Implementation

[0029] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0030] like Figures 1-5 The tabletop pretreatment grinding device shown consists of a grinding table 1 assembly, a surface grinding assembly, and a drive assembly 6.

[0031] Grinding Table 1 Assembly: The grinding table 1 assembly is the basic support structure of the entire grinding device. It includes the grinding table 1 and multiple support legs 2 located on the underside of the grinding table 1. These support legs 2 support the grinding table 1 upwards, ensuring its stability. The grinding table 1 is designed as a hollow structure and is connected to a negative pressure device. An array of negative pressure holes 3 are provided on the upper surface of the grinding table 1. When the grinding table plate is placed on the grinding table 1, the negative pressure device generates suction through the negative pressure holes 3, firmly adhering the table plate to the grinding table 1. This design ensures the stability of the table plate during the grinding process, preventing displacement due to grinding vibration, thereby ensuring grinding accuracy. On the other hand, the negative pressure adsorption method can accommodate table plates of different sizes and shapes, improving the equipment's adaptability to table plates.

[0032] Surface Grinding Assembly: The surface grinding assembly is movably mounted on the grinding table 1 and is a key component for grinding the table surface. It contains a laterally movable grinding wheel 5, which is driven to rotate by a power source. When the grinding wheel 5 rotates, its surface contacts the table surface, grinding the surface through friction to remove uneven parts and achieve the flatness and roughness requirements for membrane pressing. The surface grinding assembly includes a main crossbeam 4, within which a movable transverse support is installed. The transverse support is located on the main crossbeam 1. The main body frame 4 is equipped with a commonly used drive mechanism, and the transverse shifter is equipped with an independent power source. This allows the transverse shifter to move along the main body frame 4, thereby driving the grinding wheel 5 to adjust its position in the lateral direction. This design enables precise grinding of different positions on the table, improving the uniformity and comprehensiveness of grinding. A motor is installed on the transverse shifter, and the output shaft of the motor is connected to the grinding wheel 5. The rotation of the motor provides rotational power to the grinding wheel 5, ensuring that the grinding wheel 5 can work efficiently and stably.

[0033] Drive assembly 6: Drive assembly 6 is located on both sides of the grinding table 1 and can move synchronously and in a controlled manner along both sides of the grinding table 1. The two ends of the surface grinding component are respectively connected to the two drive assemblies 6. By moving the drive assembly 6, the surface grinding component is driven to move longitudinally above the grinding table 1, thereby realizing the grinding of the entire table surface. The drive assembly 6 is equipped with a lifting mechanism, which is used to control the lifting of the surface grinding component. Through the lifting mechanism, the distance between the grinding wheel 5 and the table surface can be precisely adjusted according to the thickness of the table and the requirements of the grinding process, ensuring that the grinding wheel 5 and the table surface maintain a suitable contact pressure, which can not only ensure the grinding effect, but also avoid the problem of damaging the table due to excessive pressure or insufficient grinding due to insufficient pressure.

[0034] In this embodiment, the drive assembly 6 uses a mature drive mechanism, which includes a slide groove provided along both sides of the grinding table 1 and a slide groove 7 provided at the slide groove. The slide groove 7 is connected to the end of the main cross frame 4. The lifting mechanism (included in the slide groove 7, not shown in the figure) includes a lead screw and a lead screw nut. The lead screw is driven to rotate by a motor. The lead screw nut is connected to the end of the main cross frame 4. The rotation of the lead screw drives the lead screw nut and the main cross frame 4 to rise and fall.

[0035] The grinding table 1 assembly also includes a debris collection structure 8 located on one side of the grinding table 1. The debris collection structure 8 is a collection tank. During the grinding process, a large amount of debris is generated. The collection tank can effectively collect these debris. The collection tank has a slag discharge port 9 in the middle. The slag discharge port 9 is connected to a slag discharge pipe 10 on its lower side. The debris generated during grinding enters the slag discharge pipe 10 through the slag discharge port 9 and is finally transported to the designated collection position. This effectively prevents debris from scattering in the working area, keeps the working environment clean, and also prevents debris from causing wear to other parts of the grinding device, thus extending the service life of the equipment.

[0036] In addition, slidable pushing components 11 are provided at both ends of the debris collection structure 8. During the debris collection process, the slidable pushing components 11 can push the debris located at both ends of the debris collection structure 8 toward the slag discharge port 9 in the middle, improve the efficiency of debris collection, ensure that the debris can pass through the slag discharge port 9 more smoothly into the slag discharge pipe 10, avoid debris accumulation in the collection structure, and further improve the effect of debris cleaning.

[0037] The surface polishing assembly also includes a debris removal device located on its side, which is used to remove the debris generated during polishing from the table, as a supplement to the debris collection structure 8, to further enhance the debris removal effect.

[0038] like Figures 2-3 As shown, the debris removal device has two different structural forms. One is a negative pressure box 12 structure. The negative pressure box 12 is connected to the negative pressure machine through a negative pressure pipe 13. A negative pressure suction port is set on the side of the negative pressure box 12 facing the grinding table 1. During the grinding process, the negative pressure machine creates a negative pressure inside the negative pressure box 12 through the negative pressure pipe 13. The negative pressure suction port can promptly suck away debris from the surface of the table, effectively preventing debris from remaining on the surface of the table and affecting the grinding quality. Figures 4-5As shown, another type is the cleaning box 14 structure. The cleaning box 14 is equipped with a circulating conveyor belt 16 driven by a power wheel 15. The power wheel 15 is driven to rotate by a power motor 17. The outer surface of the conveyor belt 16 is equipped with brushes 18. The power wheel 15 can be a smooth wheel or a gear. Correspondingly, the conveyor belt 16 can be a rubber belt or a chain plate structure. When the cleaning box 14 is working, the power motor 17 drives the power wheel 15 to rotate, which drives the circulating conveyor belt 16 to run. The brushes 18 on the outer surface of the conveyor belt 16 move accordingly, sweeping the debris off the grinding table 1. Through this mechanical cleaning method, the debris on the surface of the table can also be cleaned efficiently.

[0039] In addition, a soft baffle 19 is installed on the lower edge of the debris cleaning device's housing. The soft baffle 19 is made of a relatively soft plastic strip or cloth strip and contacts the table. When the negative pressure box-type debris cleaning device is working, although the negative pressure suction port can adsorb most of the debris, some debris may escape to the surrounding area due to airflow disturbance. The soft baffle 19 forms a physical barrier, which, in contact with the table surface, can effectively block these debris that are trying to escape, making it easier for them to be sucked into the negative pressure suction port, thereby improving the debris cleaning efficiency and ensuring a higher level of cleanliness on the table surface. For the cleaning box-type debris cleaning device, during the process of brush cleaning debris, the soft baffle 19 can guide the debris to move in a predetermined direction, preventing debris from splashing everywhere, so that the debris is cleaned and collected more concentratedly, improving the overall cleaning effect.

[0040] Regarding the settings of brush 18, brush 18 can be set with alternating hard and soft bristles, such as 10cm soft bristles - 10cm hard bristles - 10cm soft bristles. This setting can effectively remove debris from grooved countertops. The hard bristles will carry most of the debris out of the grooves, while the soft bristles can sweep up the remaining debris.

[0041] It should be noted that, in order to avoid excessive damage to the surface of the table from the stiff bristles, the hardness of the bristles must be strictly controlled to keep the damage to the table within the requirements of quality inspection.

[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
