Description

Technical Field

[0001] The utility model relates to the technical field of wood grinding machines, in particular to a grinding head disassembly component of a wood grinding machine. Background Art

[0002] The wood processing industry has become one of the manufacturing industries with relatively fast development speed and good prospects in China. Its growth rate far exceeds the average level of the entire manufacturing industry. Wood grinding is a part of wood processing. During the processing of wooden boards, it is necessary to appropriately grind the surface of the wooden boards to remove burrs on the wood surface, etc.

[0003] The grinding wheel on the wood grinding machine will wear during long-term use, and users need to replace the grinding wheel. Most grinding wheels are fixed on the rotating shaft by bolts. When the rotating shaft rotates and vibrates, the bolts have the risk of displacement and loosening. When the bolts are tightened too tightly, it is more inconvenient to disassemble and assemble. This makes it difficult for workers to replace the grinding wheel by hand, and supporting tools are required for disassembly and assembly, which is time-consuming and laborious. Therefore, a grinding head disassembly component of a wood grinding machine is needed to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems put forward in the above background art.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A grinding head disassembly component of a wood grinding machine, including a vertical frame, a disassembly and assembly component is installed at the top of the vertical frame. The disassembly and assembly component includes a driving motor installed inside the vertical frame. The left and right sides of the output end of the driving motor are connected with rotating shafts, and fixed disks are fixedly connected to the surfaces of the rotating shafts. A grinding wheel is sleeved outside the rotating shafts, and a movable disk abuts against the right side of the grinding wheel. A threaded sleeve is threadedly sleeved at a position close to the movable disk on the outer side of the rotating shaft, and limiting components are symmetrically and movably installed on the outer surface of the rotating shaft.

[0007] Preferably, column ends are arranged inside the fixed disk and the movable disk, and the column ends are inserted into the grinding wheel through positioning grooves. The column ends of the fixed disk and the movable disk can be inserted into the positioning grooves of the grinding wheel, and then the grinding wheel can be locked and fixed.

[0008] Preferably, a limiting ring is connected to the outer side of the movable disk, and the right side of the limiting ring is inserted into the threaded sleeve through an annular groove. The annular groove of the threaded sleeve can limit the limiting ring, so that the limiting ring can rotate inside the annular groove of the threaded sleeve.

[0009] Preferably, the limiting component includes a clamping plate rotatably mounted on the surface of the rotating shaft. The clamping plate is inclined. A return spring is connected to the inner wall of the clamping plate, and the bottom end of the return spring is fixedly connected to the inner wall of the rotating shaft. The return spring's resilience supports the clamping plate, causing the left side of the clamping plate to abut against the outside of the threaded sleeve, preventing the threaded sleeve from loosening and displacing during vibration.

[0010] Preferably, a nut is threadedly sleeved on the end of the rotating shaft. Two support rods are movably mounted on the left side of the nut through an annular groove, and the left sides of the support rods abut against the outside of the threaded sleeve. By the support rods abutting against the outside of the threaded sleeve, the stability of the threaded sleeve is further improved.

[0011] Preferably, two bracket components are symmetrically mounted on the left and right sides of the vertical frame. The bracket component includes a slider. A hydraulic cylinder is connected to the bottom end of the slider, and the hydraulic cylinder is mounted on the inner wall of the vertical frame through a groove. The slider is embedded in the vertical frame through a guide groove. A support plate is connected to the outside of the slider. By the telescopic movement of the output end of the hydraulic cylinder, the movement of the slider can be controlled, causing the slider to drive the support plate to move, and then the height of the support plate can be adjusted.

[0012] Preferably, support plates are symmetrically connected to the bottom end of the support plate, and guide wheels are rotatably mounted at the bottom ends of the support plates. The guide wheels are in contact with the surface of the vertical frame. By the guide wheels abutting against the side of the vertical frame, the support plate is prevented from sagging and deforming under force.

[0013] The utility model has at least the following beneficial effects:

[0014] 1. By setting the disassembly and assembly component and the limiting component, the restraint and positioning of the grinding wheel are realized. Compared with the traditional structure, in this device, the grinding wheel and the threaded sleeve are sequentially sleeved on the surface of the rotating shaft, the threaded sleeve is threadedly sleeved on the surface of the rotating shaft, and the shaft ends of the fixed plate and the movable plate are inserted on the side of the grinding wheel, and then the grinding wheel can be quickly installed. At the same time, the resilience of the return spring can push the clamping plate, and after the clamping plate rotates, it can abut against the outside of the threaded sleeve to prevent the threaded sleeve from loosening, which is convenient for the staff to quickly disassemble and assemble the grinding wheel.

[0015] 2. By setting the bracket component, the height adaptation adjustment of the support plate is realized. In this device, through the telescopic movement of the output end of the hydraulic cylinder, the slider can be pushed to move. During the movement of the slider, the support plate can be pushed, and then the position of the support plate is changed, so that the distance between the support plate and the grinding wheel can be adjusted, which is convenient for adaptively grinding the plate.

Detailed implementation manners

[0022] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0023] Refer to Figures 1-4 , a grinding head disassembly component of a wood grinding machine, including a vertical frame 1, a disassembly and assembly component 2 is installed at the top of the vertical frame 1. The disassembly and assembly component 2 includes a drive motor 21 installed inside the vertical frame 1. The left and right sides of the output end of the drive motor 21 are connected with rotating shafts 22, and a fixed disk 23 is fixedly connected to the surface of the rotating shaft 22. A grinding wheel 24 is sleeved outside the rotating shaft 22, and the right side of the grinding wheel 24 abuts against a movable disk 25. A threaded sleeve 27 is threadedly sleeved outside the rotating shaft 22 near the movable disk 25, and limiting components 3 are symmetrically and movably installed on the outer surface of the rotating shaft 22.

[0024] The inner sides of the fixed disk 23 and the movable disk 25 are provided with column ends, and the column ends are inserted into the grinding wheel 24 through the positioning grooves.

[0025] The outer side of the movable disk 25 is connected with a limiting ring 26, and the right side of the limiting ring 26 is inserted into the internal thread sleeve 27 through the annular groove.

[0026] The limiting component 3 includes a clamping plate 31 rotatably installed on the surface of the rotating shaft 22. The clamping plate 31 is designed to be inclined. The inner wall of the clamping plate 31 is connected with a return spring 32, and the bottom end of the return spring 32 is fixedly connected with the inner wall of the rotating shaft 22.

[0027] The end of the rotating shaft 22 is sleeved with a nut 29 in a threaded manner. The left side of the nut 29 is movably installed with two support rods 28 through an annular groove, and the left sides of the support rods 28 abut against the outer side of the threaded sleeve 27.

[0028] Two bracket components 4 are symmetrically installed on the left and right sides of the vertical frame 1. The bracket component 4 includes a slider 41. The bottom end of the slider 41 is connected with a hydraulic cylinder 42, and the hydraulic cylinder 42 is installed in the inner wall of the vertical frame 1 through a groove. The slider 41 is embedded in the vertical frame 1 through a guide groove, and the outer side of the slider 41 is connected with a support plate 43.

[0029] The bottom end of the support plate 43 is symmetrically connected with support plates 44, and the bottom ends of the support plates 44 are rotatably installed with guide wheels 45, and the guide wheels 45 are attached to the surface of the vertical frame 1.

[0030] When the grinding wheel 24 is sleeved on the surface of the rotating shaft 22, the column ends of the fixed disk 23 and the movable disk 25 can be inserted into the positioning groove of the grinding wheel 24, and then the grinding wheel 24 can be locked and fixed to ensure the stability of the installation of the grinding wheel 24 and prevent the grinding wheel 24 from loosening easily. The limiting ring 26 can be limited through the annular groove of the threaded sleeve 27, so that the limiting ring 26 can rotate inside the annular groove of the threaded sleeve 27, and then it is convenient for the threaded sleeve 27 to rotate independently, avoiding affecting the docking state between the column end of the movable disk 25 and the grinding wheel 24 when the threaded sleeve 27 rotates. When the threaded sleeve 27 is rotated and adjusted to a specified position, the clamping plate 31 can be supported by the resilience of the return spring 32, and then the left side of the clamping plate 31 abuts against the outside of the threaded sleeve 27, which can prevent the threaded sleeve 27 from loosening and displacing during vibration. By sleeving a nut 29 on the thread at the end of the rotating shaft 22, the nut 29 is rotated and moved to push the support rod 28 to move, and then the support rod 28 can abut against the outside of the threaded sleeve 27 to further improve the stability of the threaded sleeve 27. By the telescopic movement of the output end of the hydraulic cylinder 42, the movement of the slider 41 can be controlled, and the slider 41 drives the support plate 43 to move, and then the height of the support plate 43 can be adjusted so that the distance between the support plate 43 and the grinding wheel 24 can adapt to the size of the grinding wheel 24. The slider 41 can be guided through the guide groove of the vertical frame 1 to ensure the stability of the movement of the slider 41. The guide wheel 45 can be suspended by the support plate 44, and the guide wheel 45 abuts against the side of the vertical frame 1 to prevent the support plate 43 from sagging and deforming under force.

[0031] Working principle: According to the attached Figure 2 And the attached Figure 3 As shown, when disassembling and assembling the grinding wheel 24, the grinding wheel 24 and the movable disk 25 can be sleeved on the surface of the rotating shaft 22 in sequence. At this time, the side of the grinding wheel 24 can be engaged with the column end of the fixed disk 23. At the same time, when the threaded sleeve 27 is twisted, the threaded sleeve 27 can be pushed to move the movable disk 25, and then the column end inside the movable disk 25 is separated from the grinding wheel 24. After the movement adjustment of the threaded sleeve 27 is completed, the clamping plate 31 is supported by the resilience of the return spring 32, and the left side of the clamping plate 31 abuts against the outside of the threaded sleeve 27, which is convenient for positioning the threaded sleeve 27 and preventing the grinding wheel 24 from loosening easily;

[0032] Secondly, according to the attached Figure 4 As shown, the staff can start the hydraulic cylinder 42, so that the telescopic movement of the output end of the hydraulic cylinder 42 pushes the slider 41 to move. The movement of the slider 41 drives the support plate 43 to move, and the movement of the support plate 43 can push the plate material, and then the distance between the support plate 43 and the grinding wheel 24 is adjusted, so as to facilitate the staff to grind the wooden board.
