Description

Technical Field

[0001] This utility model belongs to the technical field of gang saws, specifically relating to a gang saw drive mechanism. Background Technology

[0002] Stone gang saws are specialized equipment used to cut large blocks of stone into thin stone slabs. After subsequent grinding and cutting processes, the stone slabs are used to make building materials such as flooring, feature walls, and countertops. In most existing stone gang saws, the drive mechanism and the gang saw frame are connected on one side for rotation. Long-term use can easily cause uneven stress on the drive mechanism, thus affecting the normal operation of the gang saw. Therefore, a gang saw drive mechanism is needed to solve the above problems. Utility Model Content

[0003] The purpose of this utility model is to provide a gang saw drive mechanism in which a motor drives a round shaft to rotate via a first pulley, a belt, and a second pulley. The round shaft synchronously drives the elliptical rods on both sides to rotate. The elliptical rods on both sides drive the square frame to move via connecting rods. When the first pulley rotates, it drives the square frame to move in a straight line repeatedly, thereby cutting the raw material through the gang saw blade. This ensures the smooth operation of the device and improves the stability of the device during operation.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0005] A gang saw drive mechanism includes a base, on which a plurality of linearly distributed support columns are fixedly mounted on the upper side. A top plate is fixedly mounted on the upper side of the plurality of support columns. Two lifting platforms symmetrically distributed front and rear are slidably mounted on the upper side of the base. A plurality of linearly distributed electric telescopic rods are fixedly mounted on the upper side of the top plate. The output ends of the plurality of electric telescopic rods located on the same side are fixedly connected to the lifting platforms. A square frame is slidably mounted between the two lifting platforms. A plurality of gang saw blades linearly distributed are installed in the square frame. A circular shaft is rotatably mounted on the upper side of the base. A first pulley is concentrically fixed on the circular shaft. A second pulley is rotatably mounted on the upper side of the base. A belt is installed between the first pulley and the second pulley. A motor is mounted on the upper side of the base. The output shaft of the motor is drivenly connected to the second pulley. Elliptical rods are fixedly mounted on the front and rear sides of the circular shaft. A connecting rod is hinged between the two elliptical rods and the side wall of the square frame.

[0006] Both of the lifting platforms have an internal elongated cavity, and both of the lifting platforms have an elongated opening on their upper sides that communicates with the elongated cavity. Several U-shaped rods are fixedly arranged linearly on the upper side of the frame. The U-shaped rods are arranged symmetrically front to back, and several rollers that match the elongated cavity are rotatably mounted on the opposite sides of the U-shaped rods.

[0007] The upper side of the frame has several mounting slots symmetrically distributed from left to right. Each of the gang saw blades has a mounting block fixed to its left and right sides, matching the mounting slot. Each of the mounting slots has a long groove on its sidewall, and a limit block is slidably fitted into each of the long grooves. A spring is fixed between the sidewall of each limit block and the corresponding sidewall of the long groove.

[0008] A square groove is provided on the lower side wall of the top plate, and several nozzles are installed in the square groove in a linear distribution.

[0009] Each of the aforementioned support columns is fixedly provided with a slide rail that matches the lifting platform on one side.

[0010] In this invention, the motor drives the round shaft to rotate via the first pulley, the belt, and the second pulley. The round shaft synchronously drives the elliptical rods on both sides to rotate. The elliptical rods on both sides drive the square frame to move via the connecting rod. When the first pulley rotates, it drives the square frame to move in a straight line repeatedly, thereby cutting the raw material through the gang saw blade. This ensures the smooth operation of the device and improves the stability of the device during operation. Attached Figure Description

Detailed Implementation

[0020] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1-6 As shown, a gang saw drive mechanism of this utility model includes a base 1. A plurality of linearly distributed support columns 10 are fixedly mounted on the upper side of the base 1. A top plate 11 is fixedly mounted on the upper side of the plurality of support columns 10. Two symmetrically distributed lifting platforms 12 are slidably mounted on the upper side of the base 1. A plurality of linearly distributed electric telescopic rods 13 are fixedly mounted on the upper side of the top plate 11. The output ends of the electric telescopic rods 13 located on the same side are all fixedly connected to the lifting platforms 12. A square frame 14 is slidably mounted between the two lifting platforms 12. Several linearly distributed gang saw blades 15 are installed inside the frame 14. A round shaft is rotatably mounted on the upper side of the base 1. A first pulley 16 is concentrically fixed on the round shaft. A second pulley 17 is rotatably mounted on the upper side of the base 1. A belt 18 is installed between the first pulley 16 and the second pulley 17. A motor 19 is installed on the upper side of the base 1. The output shaft of the motor 19 is connected to the second pulley 17 for transmission. Elliptical rods 20 are fixed on both the front and rear sides of the round shaft. A connecting rod 21 is hinged between the two elliptical rods 20 and the side wall of the square frame 14.

[0022] When using this utility model, the user places the raw material on the upper side of the base 1, starts the motor 19, and the output shaft of the motor 9 drives the second pulley 17 to rotate. The second pulley 17 drives the first pulley 16 to rotate through the belt 18. The first pulley 16 drives the round shaft to rotate synchronously. The round shaft drives the elliptical rods 20 on both sides to rotate synchronously. The elliptical rods 20 on both sides drive the two connecting rods 21 to move synchronously. The two connecting rods 21 drive the square frame 14 to slide between the two lifting platforms 12. When the two elliptical rods 20 rotate, they drive the square frame 14 to reciprocate linearly through the connecting rods 21. The output end of the electric telescopic rod 13 extends synchronously, driving the lifting platforms 12 on both sides to descend synchronously, so that the gang saw blade 15 in the square frame 14 cuts the raw material. The structure is simple and easy to use.

[0023] Furthermore, by using several electric telescopic rods 13 to drive the lifting platform 12 to move up and down, thereby driving the square frame 14 to move up and down, the contact strength between the gang saw blade 15 and the raw material is increased, and the cutting efficiency is improved.

[0024] In this invention, the motor drives the round shaft to rotate via the first pulley, the belt, and the second pulley. The round shaft synchronously drives the elliptical rods on both sides to rotate. The elliptical rods on both sides drive the square frame to move via the connecting rod. When the first pulley rotates, it drives the square frame to move in a straight line repeatedly, thereby cutting the raw material through the gang saw blade. This ensures the smooth operation of the device and improves the stability of the device during operation.

[0025] Both lifting platforms 12 have an internal long cavity 25. Both lifting platforms 12 have an upper opening that communicates with the long cavity 25. Several U-shaped rods 26 are fixed on the upper side of the frame 14 in a linear distribution. Several U-shaped rods 26 are arranged symmetrically in front and behind. Several rollers 27 that match the long cavity 25 are rotatably mounted on the opposite side of the several U-shaped rods 26.

[0026] During the use of this utility model, when the first pulley 16 drives the square frame 14 to move through the elliptical rod 20 and the connecting rod 21, the square frame 14 moves through the U-shaped rod 26 and the roller 27. The roller 27 abuts against the upper and lower side walls of the long cavity 25, so that the square frame 14 moves up and down with the lifting platform 12, thereby limiting the square frame 14 and ensuring the normal use of the square frame 14.

[0027] Furthermore, the U-shaped rod 26 is installed on the upper side of the frame 15, so that the frame 15 is located under the two lifting platforms 12. When processing raw materials, it prevents residues and waste from entering the long cavity 25, thereby ensuring the normal rotation of the roller 27.

[0028] The upper side of the frame 14 has several symmetrically distributed mounting slots 30. Each of the several gang saw blades 15 has a mounting block fixed to its left and right sides, matching the mounting slot 30. Each side wall of the mounting slots 30 has a long groove 31. Each long groove 31 has a slidable limit block 32. A spring 33 is fixed between the side wall of each limit block 31 and the corresponding side wall of the long groove 31.

[0029] During the use of this utility model, the limiting block 31 extends out of the long groove 31 under the elastic action of the spring 33, and the limiting block 31 abuts against the mounting blocks on both sides of the gang saw blade 15 to limit the gang saw blade 15 and ensure the normal usability of the gang saw blade 15.

[0030] When the hacksaw blade 15 needs to be replaced during the use of this utility model, the user only needs to press the limiting blocks 32 on both sides into the long groove 31 at the same time, and then slide the hacksaw blade 15 upward to take it out, which facilitates the quick replacement of the hacksaw blade 15 and improves the ease of use of this device.

[0031] Furthermore, the upper side of several limiting blocks 31 is machined into a bevel, so when installing the gang saw blade 15, there is no need to operate the limiting blocks 31, and the gang saw blade 15 can be installed directly, saving the installation time of the gang saw blade 15.

[0032] A square groove 35 is provided on the lower side wall of the top plate 11, and several linearly distributed spray nozzles 36 are installed in the square groove 35 to spray water on the running gang saw blade 15 and raw materials, reduce the temperature of the gang saw blade 15, and ensure the smooth use of the device.

[0033] Several support columns 10 are fixedly provided with slide rails 40 on opposite sides to match the lifting platform 12; the sliding of the lifting platform 12 is limited to ensure the temperature movement of the lifting platform 12.

[0034] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
