Description

Technical Field

[0001] The utility model relates to the technical field of cutting machines, in particular to a cutting machine with a protective structure for processing desk table tops. Background Art

[0002] The main function of the desk top is to provide a spacious platform for placing textbooks, exercise books, stationery and other learning supplies. It also has the function of adjusting height and angle to adapt to students of different ages and ensure learning comfort and correct posture.

[0003] When processing desk tops, a cutting machine is generally used to cut the desk boards. However, when cutting smaller boards, the operator will use his hands to push the boards into the cutting disc. Because the distance between the hand and the cutting disc is relatively close when pushing, this may cause the hand pushing the board to be cut by the cutting disc. Utility Model Content

[0004] The purpose of the present utility model is to provide a cutting machine with a protective structure for processing a desk table top, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a cutting machine with a protective structure for processing desk table tops, comprising a cutting table, a motor fixedly mounted on the bottom of the cutting table, a rotating shaft fixedly mounted on the output end of the motor, a cutting disc fixedly mounted on the outer wall of the rotating shaft, a pushing mechanism provided on the top of the cutting table, a protective mechanism provided on the top of the cutting table, and the pushing mechanism comprising:

[0006] A push groove is provided on the top of the cutting table, a U-shaped rod is slidably mounted inside the cutting table, and a rotating column is rotatably mounted at the through hole of the U-shaped rod;

[0007] The notch groove is opened on the front of the cutting table, the inner wall of the push groove is slidably installed with a slider, and the left side of the U-shaped rod is fixedly installed on the right side of the slider.

[0008] Preferably, a spring is fixedly installed on the right side of the inner wall of the push groove, which can reset the slider when the rotating column is not clamped in the notch groove. The end of the spring away from the push groove is fixedly installed on the right side of the slider, and a rotating rod is rotatably installed on the inner wall of the slider.

[0009] Preferably, a first torsion spring is fixedly installed on the left side of the inner wall of the slider, which can reset the rotating rod and make the L-shaped plate stand upright when the L-shaped plate is not squeezed. The end of the first torsion spring away from the slider is fixedly installed on the outer wall of the rotating rod, and the L-shaped plate is fixedly installed on the outer wall of the rotating rod.

[0010] Preferably, a bolt is threadedly connected to the through hole at the top of the L-shaped plate, a rubber disc is rotatably mounted on the bottom of the bolt, and a pushing block is fixedly mounted on the left side of the inner wall of the pushing groove.

[0011] Preferably, the protective mechanism includes: a hidden groove, which is opened on the side wall of the pushing groove to facilitate hiding the second torsion spring to prevent wood chips from splashing onto the second torsion spring when the cutting machine is working. A rotating rod is rotatably installed on the left side of the hidden groove, and a second torsion spring is fixedly installed on the left side of the hidden groove, which can make the protective plate stand upright when the squeezing rod is not squeezed, thereby facilitating the rotation and reset of the L-shaped plate.

[0012] Preferably, the end of the second torsion spring away from the hidden groove is fixedly installed on the outer wall of the rotating rod, and a protective plate is fixedly installed on the outer wall of the rotating rod. The outer wall of the rotating rod is fixedly installed with an extrusion rod, which can be squeezed by the L-shaped plate to rotate the rotating rod, and the bolt will not contact the protective plate.

[0013] Compared with the prior art, the present invention provides a cutting machine with a protective structure for processing desk tops, which has the following beneficial effects:

[0014] 1. The desk table top processing is equipped with a cutting machine with a protective structure. When it is necessary to cut smaller plates, the rotating column is rotated to move it out of the notch. At this time, the spring will reset the U-shaped rod and the slider. Because the L-shaped plate is separated from the pushing block, the first torsion spring will reset the rotating rod to make the L-shaped plate stand upright. The smaller plate is placed between the slider and the L-shaped plate, and it is fixed by tightening the bolts. Then the motor is started to rotate the cutting disk. By pushing the U-shaped rod, the slider can drive the plate to move, thereby cutting the plate. This can prevent the plate from being too small and causing the cutting disk to cut the operator's hand.

[0015] 2. The desk table top processing uses a cutting machine with a protective structure. When the U-shaped rod is pushed to the end, the pushing block will push the L-shaped plate to flip over. When flipping, the L-shaped plate will squeeze the squeezing rod, causing the rotating rod to drive the protective plate to rotate, so that the protective plate and the cutting table are in a horizontal position. This can prevent wood chips from entering the pushing mechanism when cutting large plates, causing the pushing mechanism to get stuck. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] like Figures 1-6 As shown, the utility model provides a technical solution: a cutting machine with a protective structure for processing desk table tops, comprising a cutting table 1, a motor 2 is fixedly mounted on the bottom of the cutting table 1, a rotating shaft 3 is fixedly mounted on the output end of the motor 2, a cutting disc 4 is fixedly mounted on the outer wall of the rotating shaft 3, a pushing mechanism 5 is provided on the top of the cutting table 1, and a protective mechanism 6 is provided on the top of the cutting table 1.

[0024] Specifically, the pushing mechanism 5 includes: a pushing groove 51, a U-shaped rod 52, a rotating column 53, a notched groove 54, a slider 55, a spring 56, a rotating rod 57, a first torsion spring 58, an L-shaped plate 59, a bolt 510, a rubber disc 511, and a pushing block 512. The pushing groove 51 is opened on the top of the cutting table 1, and the U-shaped rod 52 is slidably installed inside the cutting table 1. The rotating column 53 and the notched groove 54 are rotatably installed at the through hole of the U-shaped rod 52. The notched groove 54 is opened on the front of the cutting table 1, and the inner wall of the pushing groove 51 is slidably installed. The left side of the U-shaped rod 52 is fixedly mounted on the right side of the slider 55, and a spring 56 is fixedly mounted on the right side of the inner wall of the push groove 51. When it is necessary to cut a smaller plate, the rotating column 53 is rotated to align the protrusion of the rotating column 53 with the notch of the notch groove 54. At this time, the spring 56 will reset the slider 55, and the slider 55 will push the U-shaped rod 52 to reset. The end of the spring 56 away from the push groove 51 is fixedly mounted on the right side of the slider 55. A rotating rod 57 is rotatably mounted on the inner wall of the slider 55. The left side of the inner wall of the slider 55 is fixed. A first torsion spring 58 is fixedly installed. One end of the first torsion spring 58 away from the slider 55 is fixedly installed on the outer wall of the rotating rod 57. An L-shaped plate 59 is fixedly installed on the outer wall of the rotating rod 57. Because the L-shaped plate 59 will be separated from the pushing block 512 after the slider 55 is moved out, the first torsion spring 58 will reset the rotating rod 57 to make the L-shaped plate 59 stand upright. A bolt 510 is threadedly connected to the through hole at the top of the L-shaped plate 59. A rubber disc 511 is rotatably installed at the bottom of the bolt 510. A pushing block 512 is fixedly installed on the left side of the inner wall of the pushing groove 51. Place a smaller plate between the slider 55 and the L-shaped plate 59, and move the rubber disc 511 downward by tightening the bolt 510. When the rubber disc 511 contacts the plate, continue to tighten the bolt 510. The bolt 510 will rotate on the top of the rubber disc 511 until the plate is fixed. Then start the motor 2 to make the shaft 3 drive the cutting disc 4 to rotate. By pushing the U-shaped rod 52, the slider 55 can drive the plate to move, thereby cutting the plate. This can prevent the plate from being too small and causing the cutting disc 4 to cut the operator's hand.

[0025] The second torsion spring 63 is fixedly installed on the left side of the hidden groove 61, and the second torsion spring 63 is fixedly installed on the outer wall of the rotating rod 62. The outer wall of the rotating rod 62 is fixedly installed with a protective plate 64. When the rotating rod 62 rotates, it drives the protective plate 64 to rotate so that the protective plate 64 and the cutting table 1 are in a horizontal position. This can prevent wood chips from entering the pushing mechanism 5 when cutting large plates, causing the pushing mechanism 5 to get stuck. The outer wall of the rotating rod 62 is fixedly installed with an extrusion rod 65. When the U-shaped rod 52 is pushed to the end, the pushing block 512 will push the L-shaped plate 59 to flip. When flipping, the L-shaped plate 59 will squeeze the extrusion rod 65, causing the rotating rod 62 to rotate, and the second torsion spring 63 twists.

[0026] Working principle: When it is necessary to cut a smaller plate, the rotating column 53 is rotated to align the protrusion of the rotating column 53 with the notch of the notch groove 54. At this time, the spring 56 will reset the slider 55, and the slider 55 will push the U-shaped rod 52 to reset. Because the L-shaped plate 59 will be disengaged from the pushing block 512 after the slider 55 is moved out, the first torsion spring 58 will reset the rotating rod 57 to make the L-shaped plate 59 stand upright, and then put the smaller plate into the middle of the slider 55 and the L-shaped plate 59, and move the rubber plate 511 downward by tightening the bolt 510. When the rubber plate 511 contacts the plate, continue to tighten the bolt 510, and the bolt 510 will rotate on the top of the rubber plate 511 until the plate is fixed. The first torsion spring 58 twists until the L-shaped plate 59 turns 90 degrees and retracts it into the pushing groove 51. The convex block of the rotating column 53 is aligned with the notch groove 54 and inserted and rotated again. In this way, the spring 56 will not reset the slider 55, which can prevent the plate from being too small, causing the cutting disc 4 to cut the operator's hand, and will not affect the cutting of large plates.

[0027] When the U-shaped rod 52 is pushed to the end, the pushing block 512 will push the L-shaped plate 59 to flip over. When flipping, the L-shaped plate 59 will squeeze the squeezing rod 65, causing the rotating rod 62 to rotate. At this time, the second torsion spring 63 twists, and when the rotating rod 62 rotates, it will drive the protective plate 64 to rotate, so that the protective plate 64 and the cutting table 1 are in a horizontal position. This can prevent wood chips from entering the pushing mechanism 5 when cutting large plates, causing the pushing mechanism 5 to get stuck.

[0028] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
