DETAILED DESCRIPTION

[0027] The present invention will be described in further detail below with reference to the accompanying drawings.

[0028] Example:

[0029] Reference Figures 1-6 The utility model discloses a baffle mechanism for a circular saw machine, comprising a base 1 and a circular saw blade 2. The circular saw blade 2 is arranged in the middle of the base 1. A positioning plate 3 is arranged on the top side of the base 1. A guard mechanism 4 is arranged on the side of the positioning plate 3. A baffle member 5 is arranged on the side of the guard mechanism 4.

[0030] The guard mechanism 4 includes a protective strip 6, a top cover 7 and a limiting slider 8. The protective strip 6 is slidably installed in the middle of the top side of the base 1, and the circular saw blade 2 is located in the protective strip 6. The number of the protective strips 6 is several, and several protective strips 6 are stacked. Two adjacent protective strips 6 are slidably connected. The number of limiting sliders 8 corresponds to the number of the protective strips 6, and the limiting slider 8 is fixedly installed on the side of the positioning plate 3 close to the protective strip 6. Each protective strip 6 is provided with a sliding groove 9 on the side close to the positioning plate 3. Each limiting slider 8 is slidably connected to the corresponding sliding groove 9. The top cover 7 is fixedly installed on the side of the positioning plate 3, and the top cover 7 is slidably connected to the protective strip 6 located at the top.

[0031] In this embodiment, when in use, the workpiece is first pressed against the baffle member 5, and then the circular saw is started. The workpiece then moves in the direction of the protective strip 6, which drives the protective strips 6 corresponding to the thickness of the workpiece to slide through the cooperation of the slider and the slide groove 9. At this time, the cutting point of the workpiece is always in the top cover 7, so as to avoid the cutting point being exposed to the outside when the workpiece is cut, and then causing the waste chips generated during cutting to be scattered to the outside, causing the waste chips to fly to the staff, thereby affecting the staff's cutting of the workpiece. The number of protective strips 6 set is several, and the specific number can be adjusted according to the actual thickness range of the workpiece used to ensure that the protective strip 6 cooperates with the protective cover of the top cover 7 to be suitable for cutting workpieces of various sizes and to avoid the effect of waste chips flying out.

[0032] In a further preferred embodiment of the present invention, Figure 3 As shown, the side of the positioning plate 3 is fixedly connected with a limiting spring piece 10, the number of the limiting spring pieces 10 corresponds to the number of the protective card strips 6, and the limiting spring pieces 10 are arranged at an angle, and the side of each limiting spring piece 10 is fitted with the side corner of the corresponding protective card strip 6.

[0033] In this embodiment, the limiting spring piece 10 provided therein can limit the corresponding protective card strip 6, so that the corresponding protective card strip 6 can break through the limiting spring piece 10 when sliding and can move smoothly, and the protective card strip 6 that is not pushed by the workpiece is limited by the limiting spring piece 10, avoiding friction with the moving protective card strip 6 and causing movement, thereby reducing the protection range of the protective cover, which can easily cause the cutting point of the workpiece to be exposed, thereby affecting the cutting of the workpiece by the staff.

[0034] In a further preferred embodiment of the present invention, Figure 1-6 As shown, the baffle member 5 includes two sliding grooves 11, the sliding groove 11 is opened on the top side of the base 1, a support rod 12 is fixedly connected in the sliding groove 11, a positioning rod 13 is slidably connected to the circumferential side of the support rod 12, a calibration plate 14 is connected between the sides of the two positioning rods 13, and a guide baffle 15 is slidably connected to the side of the calibration plate 14.

[0035] In this embodiment, the concave slide groove 9 is used to install the support rod 12, and the positioning rod 13 on the support rod 12 can slide on the support rod 12. When the workpiece moves, the two corresponding sides of the workpiece are respectively in contact with the guide baffle 15 and the calibration plate 14. Then, when the workpiece is cut and moved, the calibration plate 14 will be pushed to move, thereby driving the movement of the guide baffle 15, so that the workpiece is always in contact with the calibration plate 14 and the guide baffle 15 when cutting, thereby ensuring the stability and accuracy of the workpiece when cutting.

[0036] In a further preferred embodiment of the present invention, Figure 3-5 As shown, an adjustment groove 16 is provided on one side of the calibration plate 14 close to the guide baffle 15, and an adjustment block 17 is slidably connected in the adjustment groove 16. The adjustment block 17 is fixedly connected to the end side of the guide baffle 15, and an adjustment screw 18 is inserted into the end of the calibration plate 14. The end of the adjustment screw 18 passes through the adjustment block 17 and is threadedly connected to the adjustment block 17.

[0037] In this embodiment, when the cutting position of the workpiece needs to be changed, the adjusting screw 18 is rotated. The rotation of the adjusting screw 18 drives the movement of the adjusting block 17, and then drives the movement of the guide baffle 15, so that the distance between the guide baffle 15 and the circular saw blade 2 can be adjusted, and the cutting point of the workpiece can be adjusted when the workpiece is in contact with the guide baffle 15.

[0038] In a further preferred embodiment of the present invention, Figure 4-5 As shown, each of the protective clips 6 is fixedly connected to a push block 19 at one end close to the calibration plate 14 , and the calibration plate 14 is fixedly connected to a push bar 20 at one side close to the protective clip 6 , and the side of the push bar 20 is in contact with the push block 19 .

[0039] In this embodiment, the push block 19 is set so that when the workpiece moves and pushes a corresponding number of protective strips 6, the protective strips 6 can drive the push strips 20 to move through the corresponding number of push blocks 19, thereby driving the movement of the calibration plate 14 and the guide baffle 15 to ensure that the workpiece can continue to fit the calibration plate 14 and the guide baffle 15, thereby ensuring the stability of the workpiece during cutting.

[0040] In a further preferred embodiment of the present invention, Figure 1-2 As shown, a return spring 21 is provided on the outer peripheral side of the support rod 12 , and the ends of the return spring 21 are fixedly connected to the end side wall of the sliding groove 11 and the side wall of the positioning rod 13 respectively.

[0041] In this embodiment, the reset spring 21 provided therein will squeeze the reset spring 21 through the positioning rod 13 when the workpiece pushes a corresponding number of protective strips 6 and pushes the calibration plate 14. When the workpiece is taken out after cutting, the squeezed spring loses the squeezing force and the limit and will return to its original state, thereby pushing the movement of the positioning rod 13 and the calibration plate 14, so that the push block 19 can be pushed to move through the push strip 20, and at the same time, the corresponding number of protective strips 6 can be pushed to move, so that the calibration plate 14, the guide baffle 15 and the corresponding number of protective strips 6 are restored to their original positions.

[0042] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
