Description

Technical Field

[0001] The utility model relates to the technical field of band saw blades, in particular to a guiding device for band saw blades. Background Technique

[0002] The existing saw blade guiding structure has a single function and is only used to guide the use direction of the band saw blade. As is well known, iron filings will adhere to the side surface of the saw blade during sawing. The presence of iron filings will affect the sawing effect of the saw blade. Moreover, due to the high-speed cutting of the workpiece by the saw blade, a large amount of heat will be generated. When the temperature of the saw blade reaches a certain level, it is easy to grind the teeth of the saw blade flat. In addition, when the saw blade works at a high temperature for a long time, it will gradually become brittle and easily break and hurt the worker.

[0003] The existing Chinese patent CN218487360U discloses a guiding device for a band saw blade. In the working process of this guiding device for a band saw blade, after the liquid application block contacts the saw blade, it can brush off the iron filings on both sides of the saw blade, thereby avoiding the influence of iron filings on the sawing effect. At the same time, the peristaltic pump inputs the coolant in the liquid storage tank into the temporary storage tank, and the coolant enters the liquid application block through the penetration holes. The liquid application block can apply the coolant on the saw blade, the fan blows air upwards, and the air guide plate guides the air towards the saw blade direction, so that the coolant can be quickly evaporated, and the heat on the saw blade can be effectively taken away, thereby effectively cooling the saw blade and increasing the service life of the band saw blade.

[0004] However, in order to add the coolant into the liquid application block, the above-mentioned guiding device for a band saw blade uses a peristaltic pump to pump the coolant in the liquid storage tank into the temporary storage tank. Although this method can achieve the purpose of transporting the coolant, it only transports the coolant, and using equipment such as a peristaltic pump consumes a large amount of energy and equipment and cannot achieve the purpose of energy saving.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0023] Please refer to Figures 1-5, the present utility model provides a technical solution: a band saw blade guiding device, which includes a base 1. A chute 3 is opened at the top of the base 1. A motor 2 is fixedly installed on the right outer wall of the base 1. The output end of the motor 2 is fixedly installed with a bidirectional lead screw 4. A slider 5 is sleeved on the outer wall of the bidirectional lead screw 4 in a threaded manner. The slider 5 is slidably arranged in the chute 3. The top of the slider 5 is rotatably connected with a first rotating shaft 7 through a bearing. A side guiding wheel 6 is fixedly installed on the outer wall of the first rotating shaft 7. A temperature reduction mechanism 8 is fixedly installed on the outer wall of the slider 5;

[0024] The cooling mechanism 8 includes a shell 801, which is fixedly mounted on the outer wall of the slider 5. The top inner wall of the shell 801 is rotatably connected to a second shaft 803 through a bearing. A second friction disc 804 is fixedly mounted on the outer wall of the second shaft 803. The outer wall of the second friction disc 804 is contacted with a friction disc 1 802. The friction disc 1 802 is fixedly mounted on the outer wall of the first shaft 7. The second shaft 803 is connected to a one-way screw 1 805 through a pulley group. The top of the one-way screw 1 805 is rotatably connected to the top inner wall of the shell 801 through a bearing. A storage tank 808 is fixedly mounted on the bottom inner wall of the shell 801. A piston 809 is slidably mounted on the inner wall of the storage tank 808. A spring 8010 is fixedly mounted on the top of the piston 809. The spring 8010 The top of the housing 801 is fixedly installed with a mounting plate 8011, the outer wall thread sleeve of the one-way screw rod 805 is provided with a rectangular column 806, the bottom end of the rectangular column 806 is fixedly connected to the top of the mounting plate 8011, the interior of the storage tank 808 is connected through a pipeline and is provided with a cleaning structure 807, the cleaning structure 807 includes a mounting seat 8071, the mounting seat 8071 is fixedly installed on the back outer wall of the housing 801, the inner wall of the mounting seat 8071 is rotatably connected with a rotating shaft 3 8073 through a bearing, the outer wall fixed sleeve of the rotating shaft 3 8073 is provided with a sponge brush 8074, the inner wall of the mounting seat 8071 is fixedly installed with a spray head 8072, the interior of the spray head 8072 is connected to the interior of the storage tank 808, and the housing 801 is fixedly connected to the slider 5, so that when adjusting The position of the side guide wheel 6 can be adjusted synchronously with the position of the housing 801, and then the position of the sponge brush 8074 in the cleaning structure 807 can be adjusted, so that the sponge brush 8074 can contact the outer wall of the band saw blade, and a spring 8010 is set in the storage tank 808 to push the piston 809 to move downward, so that the coolant in the storage tank 808 is squeezed into the spray head 8072, and then sprayed from the spray head 8072 to the sponge brush 8074, so that the sponge brush 8074 can clean the band saw blade while applying the coolant on the band saw blade to cool the band saw blade, and the friction disk 1 802 and the friction disk 2 804 are in contact, so that when the side guide wheel 6 is driven to rotate during the movement of the band saw blade, the side guide wheel 6 drives the rotating shaft 1 7 to rotate, and then drives the friction disk When the second friction plate 804 rotates, the friction plate 804 drives the second rotating shaft 803 to rotate, and then drives the one-way screw rod 1 805 to rotate. The rotation of the one-way screw rod 1 805 drives the rectangular column 806 to move downward, and then drives the mounting plate 8011 to move downward. The mounting plate 8011 moves downward to squeeze the spring 8010, so that the spring 8010 further pushes the piston 809 to move downward, so as to prevent the thrust of the spring 8010 on the piston 809 from gradually decreasing during the gradual extension of the spring 8010. Because the friction plate 1 802 and the second friction plate 804 are transmitted by friction force, when the friction plate 804 is subjected to too much resistance from the rotating shaft 2 803, the friction plate 1 802 and the friction plate 2 804 can slide, so as to prevent the resistance on the friction plate 2 804 from being transmitted to the friction plate 1 802.Furthermore, it is transmitted to the first rotating shaft 7, making it difficult for the first rotating shaft 7 to rotate, and then causing the side guide wheel 6 to be unable to rotate, resulting in an increase in the frictional force between the side guide wheel 6 and the band saw blade.

[0025] A liquid inlet pipe 15 is connected and arranged on the front inner wall of the storage tank 808. A valve 16 is fixedly installed at the front end of the liquid inlet pipe 15. The coolant is replenished into the storage tank 808 through the liquid inlet pipe 15. The connection part between the liquid inlet pipe 15 and the storage tank 808 is close to the bottom inner wall of the storage tank 808, so that the coolant replenished into the storage tank 808 by the liquid inlet pipe 15 enters below the piston 809. The lower surface of the spray head 8072 is higher than the upper surface of the storage tank 808. A scraping plate 13 is fixedly installed on the inner wall of the mounting seat 8071. The outer wall of the scraping plate 13 is in contact with the outer wall of the sponge brush 8074. An avoidance groove 14 is formed at the bottom of the mounting seat 8071, and the avoidance groove 14 is located directly below the scraping plate 13. Since the sponge brush 8074 is made of elastic material, during the process of the band saw blade deflecting under force, the band saw blade can push the sponge brush 8074 to deform, and during the process of the band saw blade pushing the sponge brush 8074 to deform, the band saw blade is still in the working state, that is, the band saw blade can drive the sponge brush 8074 to rotate. During the rotation of the sponge brush 8074, the scraping plate 13 scrapes off the iron filings remaining on the sponge brush 8074, and the scraped iron filings fall from the avoidance groove 14.

[0026] A groove 12 is formed at the top of the base 1. An installation frame 10 is slidably arranged on the inner wall of the groove 12. A rear guide wheel 11 is fixedly installed at the top of the installation frame 10. The bottom of the installation frame 10 is rotatably connected to a second guide screw rod 9 through a bearing. The outer wall of the second guide screw rod 9 is threadedly connected to the inner wall of the base 1. By rotating the second guide screw rod 9, the installation frame 10 moves upward, thereby driving the rear guide wheel 11 to move upward, so that the rear guide wheel 11 contacts the bottom of the band saw blade and jacks up the band saw blade, avoiding contact between the band saw blade and the base 1 and reducing the friction between the band saw blade and the base 1.

[0027] Working principle: When in use,

[0028] Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
