Description

Technical Field

[0001] This utility model relates to the field of cement product processing technology, specifically to a cement product edge grinding device. Background Technology

[0002] Cement, a powdered hydraulic inorganic binder, forms a paste when mixed with water. It hardens in air or, even better, in water, and can firmly bind materials such as sand and stone together. Concrete made by binding crushed stone with cement not only has high strength after hardening but also resists erosion from fresh or salt water. For a long time, it has been widely used as an important binder in civil engineering, water conservancy, national defense and other projects. Cement products often have burrs on their edges, which need to be polished. Cement product edge polishing devices can remove these burrs.

[0003] For example, a grinding device for the edges and corners of cement products, as disclosed in announcement number CN220881716U, includes a processing table and a base box. An adjustment box is fixedly connected to the upper surface of the processing table. A rotating shaft is rotatably connected inside the base box. A rotating table is fixedly connected to the upper end of the rotating shaft. A limit groove is formed inside the rotating shaft. A first gear is fixedly connected to the outer surface of the rotating shaft. A second gear is rotatably connected inside the base box. A damping rod and a spring are fixedly connected inside the base box. A limit block is engaged inside the limit groove to limit the rotation shaft and prevent the rotating table from rotating during grinding. After one side of the cement product is ground, the base box moves to the right, and then the adjustment box pushes the push rod inward to move the sleeve rod, the first fixed plate, the second fixed plate, and the limit block to the left, thereby achieving the function of rotating the rotating shaft to grind the other side of the cement product.

[0004] The aforementioned patent can prevent the rotating table from rotating during grinding, but its clamping and fixing effect on cement products is poor. After the cement products are processed, it is necessary to remove the fixing. The preparatory work for grinding is cumbersome and affects the actual work efficiency of grinding.

[0005] Therefore, we propose a grinding device for the edges and corners of cement products to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a cement product edge grinding device to solve the problems mentioned in the background art, such as poor clamping and fixing effect of cement products, the need to release the fixing after processing cement products, and the cumbersome pre-grinding work, which affects the actual grinding efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cement product edge grinding device, comprising an outer shell and movable doors rotatably installed on both sides of the outer shell, a base plate installed inside the outer shell, support legs fixedly installed between the four lower corners of the base plate and the inner wall of the outer shell, a grinding wheel rotatably installed on both sides of the base plate, an electric push rod fixedly installed at the lower end of the upper inner wall of the outer shell, and a clamping assembly installed at the lower end of the electric push rod.

[0008] Preferably, the clamping assembly includes an upper clamping plate fixedly installed at the lower end of the electric actuator, and connecting grooves are provided on both sides of the upper clamping plate, with L-shaped rods slidably installed in each connecting groove.

[0009] Preferably, the lower ends of the L-shaped rods on the same side are fixedly installed with side clamping blocks, and fixing plates are fixedly installed on both sides of the inner wall of the outer shell, with the side clamping blocks slidably connected to the fixing plates.

[0010] Preferably, the fixing plate is provided with equidistant sliding grooves, and the side walls of the side clamping blocks are all fixedly installed with multiple connecting blocks at equal intervals, and the connecting blocks are slidably connected in the sliding grooves.

[0011] Preferably, a rotating wheel is rotatably mounted on each of the two side walls of the connecting block, and the rotating wheel is slidably connected to the side wall of the fixing plate.

[0012] Preferably, a second grinding wheel is rotatably mounted on the side wall of each side clamping block, and the second grinding wheel is disposed on the inner side of the side clamping block.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. When using this device to grind the edges and corners of cement products, first place the cement product on the bottom plate. Then, start the electric actuator. The start of the electric actuator will drive the clamping component at its output end to move downward. The clamping component will clamp and fix the cement product on the bottom plate. After the cement product is clamped and fixed, the grinding wheel can be used to grind both sides of the cement product. This cement product edge and corner grinding device can grind cement products of different widths through the clamping component. It is suitable for processing cement products of various thicknesses and widths.

[0015] 2. With the cooperation of the fixed plate, the upper clamping plate of the slide groove, the connecting groove, the L-shaped rod, the side clamping block, the connecting block, the rotating wheel and the grinding wheel, when the device is in use, the side clamping blocks on both sides can be moved towards the middle by pushing the upper clamping plate downward with the electric push rod, so as to automatically clamp and fix the cement products. The clamping and fixing effect of the cement products is good. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: Please refer to Figure 1 - Figure 3 A cement product edge grinding device includes an outer shell 1 and movable doors 2 rotatably installed on both sides of the outer shell 1. A base plate 3 is installed inside the outer shell 1. Support legs 31 are fixedly installed between the four lower corners of the base plate 3 and the inner wall of the outer shell 1. Grinding wheels 32 are rotatably installed on both sides of the base plate 3. An electric push rod 4 is fixedly installed at the lower end of the upper inner wall of the outer shell 1. A clamping assembly 5 is installed at the lower end of the electric push rod 4.

[0023] In this embodiment: when using the device to grind the edges and corners of cement products, the cement product can be placed on the base plate 3 first. At this time, the electric actuator 4 can be started. The start of the electric actuator 4 drives the clamping component 5 at its output end to move downward. The clamping component 5 clamps and fixes the cement product on the lower base plate 3. After the cement product is clamped and fixed, the grinding wheel 32 can be used to grind both sides of the cement product. This cement product edge and corner grinding device can grind cement products of different widths through the clamping component 5, and is suitable for processing cement products of various thicknesses and widths.

[0024] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 2 - Figure 4 The clamping assembly 5 includes an upper clamping plate 51 fixedly installed at the lower end of the electric push rod 4. Both sides of the upper clamping plate 51 are provided with connecting grooves 511, and L-shaped rods 52 are slidably installed in the connecting grooves 511. The L-shaped rods 52 slide on the side walls of the upper clamping plate 51.

[0025] A side clamping block 53 is fixedly installed at the lower end of the L-shaped rod 52 on the same side. Fixing plates 11 are fixedly installed on both sides of the inner wall of the outer shell 1. The side clamping block 53 is slidably connected to the fixing plate 11. When the L-shaped rod 52 is pushed down, it will retract into the connecting groove 511 and slide obliquely downward along the side wall of the fixing plate 11 of the side clamping block 53.

[0026] The fixed plate 11 has equidistant grooves 12. Multiple connecting blocks 54 are fixedly installed at equal intervals on the side walls of the side clamping blocks 53. The connecting blocks 54 are slidably connected in the grooves 12. The connecting blocks 54 and the grooves 12 cooperate to limit the side clamping blocks 53, so that they slide against the surface of the fixed plate 11.

[0027] Rotary wheels 55 are rotatably mounted on both sides of the connecting block 54. The rotating wheels 55 are slidably connected to the side wall of the fixing plate 11. The setting of the rotating wheels 55 can reduce the friction between the connecting block 54 and the fixing plate 11.

[0028] The side walls of the side clamping block 53 are rotatably equipped with a second grinding wheel 56. The second grinding wheel 56 is located on the inner side of the side clamping block 53, and the side clamping block 53 can grind the upper side when clamping the cement product on both sides.

[0029] In this embodiment: When using this device to grind cement products, the cement products can first be placed on the base plate 3. Then, the electric actuator 4 can be activated. The lower end of the electric actuator 4 pushes the upper clamping plate 51 downwards. At this time, the L-shaped rods 52 on both sides of the upper clamping plate 51 drive the side clamping blocks 53 to slide along the surface of the fixing plate 11. As the side clamping blocks 53 slide along the surface of the fixing plate 11, they move towards the center. At this time, the side clamping blocks 53 drive the L-shaped rods 52 to slide into the connecting groove 511 of the upper clamping plate 51. The side clamping blocks 53 then slide along the surface of the fixing plate 11. When the connecting block 54 slides along the slide groove 12, the rotating wheel 55 set on its side wall rotates and connects with the fixing plate 11, which makes it easier for the side clamping block 53 to slide. After clamping and fixing the cement product on both sides, the grinding wheel 32 and the grinding wheel 56 can be started to grind the upper and lower sides of the cement product. When using this device, the upper clamping plate 5 is pushed down by the electric push rod 4 to bring the side clamping blocks 53 on both sides closer to the middle, automatically achieving the clamping and fixing of the cement product. The clamping and fixing effect of the cement product is good.
