Description

Technical Field

[0001] The invention relates to a plate processing technology, in particular to a grinding device for producing a combined steel-wood bookshelf. Background Art

[0002] The combined steel-wood bookshelf is a common piece of furniture. It is made of wood as the board base material and steel as the frame base material. It is an organic combination of common artificial boards and steel structures. It not only has a novel style, but also significantly improves the supporting strength and stability of the bookshelf, which can better meet the needs of daily use.

[0003] During the production process of the combined steel-wood bookshelf, the wood board as the base material of the board surface will have a large number of burrs on its surface after undergoing multiple processing steps. Therefore, it needs to be polished by a polishing device. However, in the process of polishing the wood board with existing equipment, the commonly used mainstream polishing equipment can only realize single-sided polishing of the wood board, while some polishing equipment can realize double-sided synchronous polishing. However, since the side of the wood board is also prone to burrs, after one polishing, it may be necessary to manually assist in polishing or use a special side polishing device to perform secondary processing, which makes the processing of the board more inconvenient. For example, the Chinese invention patent with the authorization announcement number CN118528159B discloses an automatic template four-sided polishing device, which can polish the upper and lower and left and right four side surfaces of the wood board in sequence during operation. However, since the wood board is always in a moving state during operation, it is more inconvenient to polish its front and rear ends, so the wood board polishing equipment still has certain limitations and needs to be improved.

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] See also Figures 1-4 , a grinding device for producing a combined steel-wood bookshelf, comprising a front conveying platform 1, a transfer platform 2 and a rear conveying platform 3 which are arranged in sequence;

[0030] A loading conveyor belt 11 is provided on the front conveyor platform 1, on which bookshelf boards are placed. A first working groove is provided on the front conveyor platform 1, inside which two side grinding rollers 12 and two surface grinding rollers 13 corresponding to the bookshelf boards are sequentially provided along the conveying direction of the bookshelf boards. A first feeding roller 14 and a second feeding roller 15 are provided on both sides of the first working groove.

[0031] A rotating table 21 is provided on the top of the turntable 2, and a first accommodating groove 22 is opened in the middle of the top of the rotating table 21. The inner side surface of the first accommodating groove 22 is slidably connected to the first integrated box 23, and multiple groups of first conveying rollers 24 are provided on the first integrated box 23. Second accommodating grooves 25 are symmetrically opened on both sides of the top of the rotating table 21, and the inner side surface of the second accommodating groove 25 is slidably connected to the second integrated box 26. Multiple groups of second conveying rollers 27 are provided on the second integrated box 26. The first conveying roller 24 and the second conveying roller 27 are arranged vertically, and a lifting cylinder 28 is installed inside the first accommodating groove 22 and the second accommodating groove 25.

[0032] In this embodiment, two end grinding rollers 31 corresponding to the bookshelf boards are provided on the rear conveyor platform 3, a unloading conveyor belt 32 is provided on the rear conveyor platform 3, a second working groove is opened on the rear conveyor platform 3, the end grinding rollers 31 are arranged in the second working groove, and the rear conveyor platform 3 is provided with a third feeding roller 33 and a fourth feeding roller 34 located on both sides of the second working groove.

[0033] It should be noted that the loading conveyor belt 11, the side grinding roller 12, the surface grinding roller 13, the first feeding roller 14, the second feeding roller 15, the end grinding roller 31 and the unloading conveyor belt 32 are all driven by motors to ensure that the above components can work normally to transport or grind the bookshelf boards.

[0034] In addition, the distance between the two sets of second conveying rollers 27 is adapted to the length of the bookshelf board. The rotating platform 21 is driven by a motor, and the motor drives the rotating platform 21 to rotate intermittently, and the single rotation angle is 90°.

[0035] In addition, the first integrated box 23 and the second integrated box 26 are respectively fixedly connected to the top of the telescopic end of the corresponding lifting cylinder 28, and the depth value of the first accommodating groove 22 is greater than the combined height value of the first integrated box 23 and the first conveying roller 24, and the depth value of the second accommodating groove 25 is greater than the combined height value of the second integrated box 26 and the second conveying roller 27.

[0036] At the same time, the distance between the first feed roller 14 and the second feed roller 15, as well as the distance between the second feed roller 15 and the first conveyor roller 24 are both smaller than the length of the bookshelf board, and the distance between the second conveyor roller 27 and the third feed roller 33, as well as the distance between the third feed roller 33 and the fourth feed roller 34 are both smaller than the width of the bookshelf board, so that when the bookshelf board after being polished on all four sides is conveyed to the turntable 21, the height of the first conveyor roller 24 is slightly higher than the surface of the turntable 21, and the height of the second conveyor roller 27 is lower than the surface of the turntable 21 and is received in the second accommodating groove 25. When the bookshelf board is conveyed to contact with the first conveyor roller 24, it is conveyed by the first conveyor roller 24. The bookshelf board is symmetrically carried on the first conveying roller 24, and then the rotating table 21 is driven by the motor to rotate 90 degrees, so that the bookshelf board rotates accordingly, so that the side surfaces that are always at the front and rear ends of the conveying are adjusted to both sides of the forward direction, and then the second integrated box 26 and the second conveying roller 27 are driven to move upward by the lifting cylinder 28 corresponding to the second conveying roller 27, so that the second conveying roller 27 contacts and supports the bottom of the bookshelf board, and the lifting cylinder 28 corresponding to the first conveying roller 24 drives the first integrated box 23 and the first conveying roller 24 to move downward into the first accommodating groove 22. At this time, the second conveying roller 27 rotates to continue conveying the bookshelf board.

[0037] During operation, the bookshelf board placed on its surface is conveyed forward by the loading conveyor belt 11 and moved to the first feeding roller 14. Under the cooperation of the first feeding roller 14, the bookshelf board passes through the side grinding roller 12 and the surface grinding roller 13 in turn, and in this process, the two side grinding rollers 12 and the two surface grinding rollers 13 can cooperate to perform synchronous grinding on both sides and the upper and lower surfaces of the bookshelf board in the forward direction. Under the transportation of the first feeding roller 14, the end of the polished bookshelf board moves to the second feeding roller 15, and the polished bookshelf board continues to be conveyed forward by the second feeding roller 15, so that the bookshelf board polished on four sides is smooth. The board can be moved onto the rotating table 21, and the first conveyor roller 24 drives the bookshelf board to move to the middle part of the rotating table 21. Then the rotating table 21 rotates and drives it to rotate synchronously 90°, so that the front and rear ends in the initial state are transformed into the two sides of the current forward direction. Then, the second conveyor roller 27 continues to convey the bookshelf board forward, so that the bookshelf board moves to contact with the third feed roller 33, so that the third feed roller 33 continues to convey the bookshelf board forward, and during the conveying process, it passes through the two end grinding rollers 31, so that the end grinding rollers 31 can supplement the ungrinded surface on the bookshelf board, thereby making the one-time grinding of the bookshelf board more sufficient.

[0038] On the basis of the above embodiment, another technical solution is provided: a supporting seat 4 is provided on the side of the front conveying platform 1, a guide groove 41 is provided on the top of the supporting seat 4, a translation seat 42 is slidably connected inside the guide groove 41, two surface grinding rollers 13 are rotatably connected to the translation seat 42, a lifting seat 43 is provided at the bottom of the first working groove, two side grinding rollers 12 are rotatably connected to the surface of the lifting seat 43, a driving wheel 44 is rotatably connected to the top of the supporting seat 4, a driving column 45 is fixedly connected to the surface of the driving wheel 44, a synchronization rod 46 is fixedly connected to the side of the translation seat 42, the synchronization rod 46 is perpendicular to the guide groove 41, and a synchronization rod 46 is provided at the bottom Slot 47, the driving column 45 is slidably connected to the inner side of the synchronous groove 47, a moving groove 48 is opened inside the front conveyor platform 1, and a vertical groove connected to the moving groove 48 is opened at the bottom of the first working groove. The bottom of the lifting seat 43 is fixedly connected with a lifting column 49 corresponding to the vertical groove, and the inner side of the moving groove 48 is slidably connected with a lifting block 410 corresponding to the lifting column 49. The lifting block 410 is provided with a lifting inclined surface 411 on the side close to the lifting column 49. An installation groove is opened inside the bearing seat 4, and a driving disk 412 coaxially arranged with the driving wheel 44 is rotatably connected inside the installation groove, and a linkage rod 413 is rotatably connected between the driving disk 412 and the lifting block 410.

[0039] It should be noted that the length value of the surface grinding roller 13 is adapted to the width value of the bookshelf board, so that when the surface grinding roller 13 is driven to reciprocate along its axial direction, the surface grinding roller 13 can still fully grind the surface of the bookshelf board without any grinding dead corners.

[0040] During the grinding process, the motor drives the driving wheel 44 and the driving disc 412 to rotate synchronously. During the rotation of the driving wheel 44, the driving column 45 is driven to rotate synchronously. During the rotation of the driving column 45, a thrust is applied to the synchronization rod 46, so that the synchronization rod 46 and the translation seat 42 can reciprocate along the inner wall of the guide groove 41. During this process, the driving column 45 slides back and forth along the inner wall of the synchronization groove 47. During the reciprocating movement of the translation seat 42, it drives the surface grinding roller 13 to reciprocate along the axial direction.

[0041] When the driving disc 412 rotates, the lifting block 410 performs a linear reciprocating motion along the inner wall of the movable groove 48 under the transmission of the linkage rod 413. When it moves toward the lifting column 49, the lifting column 49 moves upward under the cooperation and push of the lifting inclined surface 411, and drives the lifting seat 43 and the side grinding roller 12 to move upward. When the lifting block 410 moves in the direction away from the lifting column 49, the lifting column 49 moves downward along the surface of the lifting inclined surface 411. Therefore, during the reciprocating movement of the lifting block 410, the side grinding roller 12 performs a synchronous reciprocating motion up and down.

[0042] An installation box 414 is provided on the rear conveyor platform 3, and the inner side surface of the installation box 414 is slidingly connected to the installation seat 415. A lifting cylinder 416 is installed on the top of the installation box 414. The bottom of the telescopic end of the lifting cylinder 416 passes through the surface of the installation box 414 and is fixedly connected to the top of the installation seat 415. In addition, the two end grinding rollers 31 are rotatably connected to the bottom of the installation seat 415.

[0043] During the grinding process, the reciprocating extension and retraction of the telescopic end of the lifting cylinder 416 can drive the mounting seat 415 to reciprocate up and down along the inner wall of the mounting box 414, and drive the end grinding roller 31 at its bottom to reciprocate up and down.

[0044] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
