Usually, it is necessary to add a corresponding number of motors to meet the driving requirements, but this will increase the processing cost. Utility Model Content

[0028] Example 1

[0029] like Figures 1-8 As shown in the figure, the carbide saw blade grinding machine proposed in this embodiment includes a machine housing 1, a grinding mechanism, a saw blade driving mechanism, and a saw blade limiting device.

[0030] A slide table 2 is slidably mounted on the chassis 1, and a first reciprocating cylinder 6 is mounted on the chassis 1 to drive the slide table 2 to reciprocate.

[0031] The grinding mechanism includes a motor 4 and multiple grinding discs 19. The multiple grinding discs 19 are arranged side by side above the slide table 2. A mounting shaft 191 is mounted on the grinding disc 19. Multiple mounting brackets 20 are arranged side by side on the slide table 2. The multiple mounting shafts 191 are rotatably mounted on the multiple mounting brackets 20 respectively. A transmission assembly is connected between two adjacent mounting shafts 191. The transmission assembly includes a synchronous belt 21 and two synchronous pulleys 22. The two synchronous pulleys 22 are respectively mounted on two corresponding mounting shafts 191. The two synchronous pulleys 22 are connected by the synchronous belt 21. The motor 4 is mounted on the slide table 2 and its output shaft is connected to the mounting shaft 191 at the end.

[0032] The saw blade drive mechanism is mounted on the housing 1. The saw blade drive mechanism includes a second reciprocating cylinder 9, a slide 15, a pawl 16, a third limiting block 17, and a third spring 18. The second reciprocating cylinder 9 is mounted on the housing 1, the slide 15 is mounted on the output shaft of the second reciprocating cylinder 9, the pawl 16 is rotatably mounted on the slide 15, the third limiting block 17 is set on the slide 15, one end of the third spring 18 is connected to the pawl 16, and the other end is connected to the side of the slide 15.

[0033] A saw blade limiting device is installed on the machine housing 1. The saw blade limiting device includes a first limiting mechanism, a second limiting mechanism, and a limiting plate 23. The first limiting mechanism includes a lifting frame 11 and two third pressure rollers 10. The lifting frame 11 is slidably installed on the machine housing 1. A first elastic connecting assembly connects the lifting frame 11 and the machine housing 1. The first elastic connecting assembly includes a first guide rod 121, a first spring 122, a first limiting block 123, and a second limiting block 124. The first guide rod 121 movably passes through the lifting frame 11. The first spring 122 is sleeved on the first guide rod 121. The first limiting block 123 and the second limiting block 124 are respectively connected to the two ends of the first guide rod 121, and the first limiting block 123 is fixed on the machine housing 1. The two third pressure rollers 10 are rotatably mounted on the machine housing 1. The second limiting mechanism includes a column 7, a first pressure roller 81, and a second pressure roller 82, which are installed at both ends of the lifting frame 11. The column 7 is vertically mounted on the housing 1, and the first pressure roller 81 is rotatably mounted on the column 7. A sliding hole 701 is provided on the column 7, and a mounting slider 13 is slidably mounted on the inner side of the sliding hole 701. A second elastic connecting assembly is connected between the mounting slider 13 and the column 7. The second elastic connecting assembly includes a second guide rod 141 and a second spring 142. The second guide rod 141 is vertically mounted on the inner side of the sliding hole 701, the mounting slider 13 is slidably mounted on the second guide rod 141, and the second spring 142 is sleeved on the second guide rod 141. The second pressure roller 82 is rotatably mounted on the mounting slider 13. Two limiting plates 23 are provided at both ends of the housing 1.

[0034] Specifically, before grinding the saw blade, it is necessary to install a limiting device. The upper part of the saw blade is placed between the first pressure roller 81 and the second pressure roller 82. The saw blade is clamped between the first pressure roller 81 and the second pressure roller 82 by the setting of the second elastic connecting component. Then, the lifting frame 11 is pulled upward to drive the third pressure roller 10 to move, and the lower part of the saw blade is placed on the machine housing 1. The two limiting plates 23 limit the toothed side of the saw blade. It should be added that a limiting rod is installed on the machine housing 1. The limiting rod is used to limit the side of the saw blade away from the teeth. After the lifting frame 11 is released, the third pressure roller 10 is pressed on the surface of the saw blade under the elastic force of the first elastic connecting component.

[0035] When motor 4 is started, it can synchronously drive multiple grinding discs 19 through the coordinated operation of multiple transmission components. The technical solution does not specify the exact number of grinding discs 19 installed; assuming three grinding discs 19 are installed, designated as discs A, B, and C, please refer to [reference needed]. Figure 8 As shown, three adjacent saw teeth on the saw blade form a group, and a group of saw teeth includes teeth A, B, and C. This ensures that discs A, B, and C always correspond to teeth A, B, and C, respectively. Furthermore, the single drive distance of the saw blade drive mechanism is the sum of the lengths of teeth A, B, and C. This achieves intermittent movement of multiple groups of saw teeth, enabling the equipment to grind multiple saw teeth at once, thereby improving work efficiency.

[0036] Example 2

[0037] like Figure 1 and Figure 2 As shown in this embodiment, a carbide saw blade grinding machine is proposed. Compared with the first embodiment, in this embodiment, a dust cover 3 is installed on the slide table 2. The dust cover 3 has a notch for the saw blade to pass through, and multiple grinding discs 19 are located inside the dust cover 3. The dust cover 3 can prevent the debris generated during the grinding process from splashing outwards. It should be added that, in order to improve the sound insulation effect, sound insulation cotton can be installed on the inner wall of the dust cover 3. A vacuum head and a vacuum cleaner 5 are installed on the inner and outer sides of the dust cover 3, respectively. A vacuum pipe is connected between the vacuum cleaner 5 and the vacuum head. During the grinding process, the vacuum cleaner 5 can be started to work, and the debris inside the dust cover 3 is sucked into the vacuum cleaner 5 through the vacuum head and the vacuum pipe.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
