Description

Technical Field

[0001] This utility model belongs to the field of feeding devices, specifically relating to a feeding device for a granite grinding machine. Background Technology

[0002] Granite is a type of stone with high hardness and wear resistance, mainly composed of minerals with high hardness such as quartz, feldspar, and mica. These properties make granite widely used in architectural decoration, outdoor landscaping, and other fields. Grinding granite is the main method to improve its aesthetics and extend its service life. Grinding is generally done using a grinding machine. Before the granite slab is fed into the grinding machine, it is usually hoisted onto the grinding machine platform by an overhead crane. However, this method is only suitable for thicker granite slabs. For 30mm thick granite slabs, they are usually stacked together and transported by forklift. Finally, they are manually pushed onto the grinding machine for grinding, which results in high labor intensity for employees. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a feeding device for a granite grinding machine. It has a simple structure and is convenient and practical. By adjusting the angle of the granite plate by adjusting the car, the granite can be adjusted according to the mechanism of the grinding machine and the continuous feeding to adjust the feeding height, so as to achieve the purpose of intelligent feeding.

[0004] A feeding device for a granite grinding machine includes an adjusting trolley, a support frame, positioning platforms, support rods, fixed frames, a lifting frame, a feeding device, lead screws, and an electric hoist. The support frame has adjusting trolleys connected to both ends. Several positioning platforms are arranged opposite each other on the support frame. At least two support rods are positioned on the support frame by the opposing positioning platforms. Two fixed frames are connected to the support frame. The lifting frame is connected to corresponding fixed frames by two lead screws. The electric hoist is mounted on the lifting frame and connected to the feeding device. The adjusting trolley includes a railcar, a lifting adjusting frame, and lifting cylinders. The lifting adjusting frame is connected to the railcar by several lifting cylinders. The support frame is hinged to the lifting adjusting frame.

[0005] Preferably, a baffle is connected to the side of the railcar away from the support frame.

[0006] Preferably, the feeding device includes a movable plate, pulleys, an adjusting seat, a material hook, and a limit switch. Several pulleys are installed on the lower side of the movable plate, the adjusting seat is connected to the movable plate, one end of the material hook is hinged to the adjusting seat, and the limit switch is installed on the material hook and cooperates with the movable plate.

[0007] Preferably, the feeding device further includes an adjusting bolt, and the adjusting seat is connected to the moving plate through the adjusting bolt.

[0008] Preferably, the end of the material hook furthest from the adjusting seat is arc-shaped.

[0009] Preferably, the movable plate is connected to at least two adjustment seats.

[0010] Beneficial effects:

[0011] (1) The present invention provides a feeding device for a granite grinding machine. It has a simple structure and is convenient and practical. By adjusting the angle of the granite plate by adjusting the car, the granite can adjust the feeding height according to the mechanism of the grinding machine and the continuous feeding, so as to achieve the purpose of intelligent feeding.

[0012] (2) The feeding device for a granite grinding machine of this utility model releases the feeding device through an electric hoist, so that the feeding device moves along the granite, and then hooks the granite slab with a material hook.

Detailed Implementation

[0017] The embodiments of this utility model are further described below with reference to the accompanying drawings.

[0018] Example 1

[0019] like Figures 1 to 3As shown; a feeding device for a granite grinding machine includes an adjusting carriage 1, a support frame 2, positioning platforms 3, support rods 4, fixed frames 5, a lifting frame 6, a feeding device 7, lead screws, and an electric hoist. The support frame 2 is connected to the adjusting carriage 1 at both ends. Several positioning platforms 3 are arranged in pairs on the support frame 2. At least two support rods 4 are positioned on the support frame 2 by the two pairs of opposing positioning platforms 3. Two fixed frames 5 are connected to the support frame 2. The lifting frame 6 is connected to the corresponding fixed frames 5 by two lead screws. The electric hoist is mounted on the lifting frame 6 and connected to the feeding device 7. The adjusting carriage 1 includes a railcar 11, a lifting adjusting frame 12, and lifting cylinders 13. The lifting adjusting frame 12 is connected to several lifting cylinders 13. 3 is connected to the railcar 11, and the support frame 2 is hinged to the lifting adjustment frame 12; a baffle 14 is connected to the side of the railcar 11 away from the support frame 2; the feeding device 7 includes a moving plate 71, pulleys 72, adjusting seats 73, material hooks 75 and limit switches, several pulleys 72 are installed on the lower side of the moving plate 71, the adjusting seats 73 are connected to the moving plate 71, one end of the material hook 75 is hinged to the adjusting seats 73, and the limit switch is installed on the material hook 75 and cooperates with the moving plate 71; the feeding device 7 also includes adjusting bolts 74, and the adjusting seats 73 are connected to the moving plate 71 through the adjusting bolts 74; the end of the material hook 75 away from the adjusting seats 73 is arc-shaped; the moving plate 71 is connected to at least two adjusting seats 73.

[0020] Beforehand, a forklift is used to place the pallet and the stacked granite slabs on it onto several support rods 4. The lifting cylinder 13 then drives the lifting adjustment frame 12 to rise and fall, causing the support frame 2 to tilt. Controlling the tilt angle of the granite slabs provides the power for the feeding device 7 to move. Simultaneously, the electric hoist releases a steel cable. When the feeding device 7 moves to one end of the granite slab, the end of the material hook 75 that is in contact with the granite falls off the granite end, causing the limit switch on the material hook 75 to move away from the support frame 2. At this point, the electric hoist starts winding up the steel cable, which pulls the feeding device 7, causing the material hook 75 to pull the granite slab towards the grinding machine. To prevent the stacked granite slabs from moving synchronously, baffles 14 are used to limit the position of the granite slabs. The baffles 14 near the grinder restrict the position of the granite slabs below the topmost granite slab in the stack. The topmost granite slab is conveyed to the grinder by the feeding device 7 to prevent the granite slabs below from being discharged synchronously. Subsequent granite slabs are lifted by the lifting adjustment frame 12 to control the discharge of individual granite slabs one by one. The end of the material hook 75 away from the adjustment seat 73 is rounded to prevent the end of the material hook 75 that is in contact with the granite from rubbing against each other and affecting the movement of the feeding device 7 when it moves.

[0021] The specific embodiments of this utility model have been described in detail above, but they are merely examples, and this utility model is not limited to the specific embodiments described above. For those skilled in the art, any equivalent modifications and substitutions to this utility model are also within the scope of this utility model. Therefore, all equivalent changes and modifications made without departing from the spirit and scope of this utility model are covered within the scope of this utility model.
