Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of heat transfer machines, and particularly relates to a new type of double-round silent guide rail applied to a heat transfer machine. Background Art
[0002] Heat transfer printers usually use guide rails to install the X-axis print head for moving printing. The existing X-axis guide rails of heat transfer printers generally use ball linear guide rails. Although this kind of linear guide rail has high moving accuracy, it needs to be lubricated regularly, and the moving friction sound is relatively large. The guide rail of the new type of double-round silent guide rail is a double-round shaft integrally formed by aluminum, and its surface is hardened by anodic treatment, which is relatively wear-resistant. At the same time, the slider is made of a special engineering plastic with self-lubrication, which not only ensures the wear resistance of the slider, but also moves smoothly and very quietly without adding lubricating oil. Therefore, we propose a new type of double-round silent guide rail applied to a heat transfer machine to facilitate smooth movement and very quiet operation during heat transfer. Content of the Utility Model
[0003] Aiming at the problems in the prior art, the utility model provides a new type of double-round silent guide rail applied to a heat transfer machine.
[0004] The technical solution adopted by the utility model to solve its technical problems is a new type of double-round silent guide rail applied to a heat transfer machine, which includes an X-axis bracket. The top of the X-shaped axis bracket is installed with an X-axis cross beam through bolts. A double-round guide rail is installed on the beam wall of the X-axis cross beam through bolts. A plastic slider is slidably connected to the upper guide rail of the double-round guide rail, and two plastic sliders are installed and slidably connected to the lower guide rail of the double-round guide rail. A servo motor is installed on the frame wall of the X-axis bracket, and a transmission wheel A is installed at the output end of the servo motor. A transmission wheel B is rotatably connected to the frame wall of the X-axis bracket, and the rail walls between the transmission wheel B and the transmission wheel A are connected by a belt.
[0005] By adopting the above technical solution, the double circular guide rails are installed on the X-axis cross beam. A plastic slider is slidably connected to the upper guide rail of the double circular guide rails, and two plastic sliders are slidably connected to the lower guide rail of the double circular guide rails. Then, the three plastic sliders are fixed to the carriage by bolts to complete the connection. The movement accuracy of the carriage is determined by three dimensions of X, Y, and Z. The X direction is the movement direction, and the accuracy in the Y direction is the front and rear clearances between the three sliders and the double circular guide rails. The accuracy in the Z direction is the upper and lower clearances between the upper and lower guide rails of the double circular guide rails and the plastic sliders. In theory, it can shake in the up, down, left, and right ZY directions. However, in practice, due to the gravity eccentricity of the carriage itself, with the lower guide rail of the double circular guide rails in the X direction as the rotation axis, the upper guide rail slider of the double circular guide rails rotates clockwise and is limited, forming a stable YZ space limit, thus achieving a very high installation accuracy. When the heat transfer printer is printing, the servo motor drives belt A. Since the rail walls between the transmission wheels A and the transmission wheels B at the X-axis bracket are connected by the belt, after the servo motor drives the transmission wheel A, the belt rotates. Since the belt is connected to the wall of the carriage, and then through the servo motor, the movement feedback is carried out through the grating scale and the grating decoder, so the belt pulls the carriage to move back and forth. During the movement, the nozzle sprays ink on the printing medium to ensure the movement accuracy of the carriage in the X axis. Since the top of the X-axis cross beam and the top of the carriage are connected by a drag chain, the ink pipe and the cable pass through the drag chain, and the drag chain ensures that the ink pipe and the cable during the movement will not be worn and pulled. Therefore, when the nozzle is moved, it moves smoothly and very quietly without adding lubricating oil.
[0006] Specifically, the plastic slider at the upper guide rail of the double circular guide rails and the plastic slider at the lower guide rail of the double circular guide rails are both connected to the carriage by bolts.
[0007] By adopting the above technical solution, the carriage can be limited and moved through the slider.
[0008] Specifically, an inkjet hot stamping nozzle is installed at the wall of the carriage.
[0009] By adopting the above technical solution, the nozzle can be connected to an external ink pipe for inkjet hot stamping.
[0010] Specifically, a grating decoder is installed at the wall of the carriage by bolts, and the grating decoder is located on one side of the grating scale. The grating scale is installed at the outer wall of the X-axis cross beam by bolts.
[0011] By adopting the above technical solution, through the movement feedback by the grating scale and the grating decoder, the stepping direction and distance of the servo motor can be adjusted.
[0012] Specifically, the belt is connected to the wall of the carriage.
[0013] By adopting the above technical solution, the rotation of the belt can drive the movement of the carriage.
[0014] Specifically, the top of the X-axis crossbeam is connected to the top of the carriage through a drag chain.
[0015] By adopting the above technical solution, the ink pipe and the cable pass through the drag chain, and the drag chain ensures that the ink pipe and the cable during movement will not be worn and pulled.
[0016] Advantages of the present utility model:
[0017] (1) A new type of double-round silent guide rail described in the present utility model is applied to a heat transfer printing machine. The double-round guide rail is installed on the X-axis crossbeam. A plastic slider is slidably connected to the upper guide rail of the double-round guide rail, and two plastic sliders are slidably connected to the lower guide rail of the double-round guide rail. Then, the three plastic sliders are fixed to the carriage through bolts to complete the connection. The movement accuracy of the carriage is determined by three dimensions of X, Y, and Z. The X direction is the movement direction, and the Y direction accuracy is the front and rear clearances between the three sliders and the double-round guide rail. The Z direction accuracy is the upper and lower clearances between the upper and lower guide rails of the double-round guide rail and the plastic sliders. In theory, it can shake in the up, down, left, and right ZY directions. However, in fact, due to the gravity eccentricity of the carriage itself, with the lower guide rail of the double-round guide rail on the X axis as the rotation axis, the slider on the upper guide rail of the double-round guide rail rotates clockwise and is limited, forming a stable YZ space limit, thereby achieving a very high installation accuracy. When the heat transfer printing machine is printing, the servo motor drives belt A. Since the rail walls between the transmission wheels A and the rail walls of the transmission wheel B at the X-axis bracket are connected by a belt, after the servo motor drives the transmission wheel A, the belt rotates. Since the belt is connected to the wall of the carriage, and then through the servo motor for motion feedback through the grating ruler and the grating decoder, the belt pulls the carriage back and forth. During the movement, the nozzle sprays ink on the printing medium to ensure the X-axis movement accuracy of the carriage. Since the top of the X-axis crossbeam is connected to the top of the carriage through a drag chain, the ink pipe and the cable pass through the drag chain, and the drag chain ensures that the ink pipe and the cable during movement will not be worn and pulled. Therefore, when the nozzle moves, it moves smoothly and very quietly without adding lubricating oil. Description of the drawings

[0024] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0025] As an embodiment of the present utility model, as Figure 1 , Figure 2 and Figure 3 shown, a new type of double circular silent guide rail described in the present utility model is applied to a heat transfer machine, including an X-axis support 13. The top of the X-axis support is installed with an X-axis cross beam 10 through bolts. A double circular guide rail 1 is installed on the beam wall of the X-axis cross beam 10 through bolts. A plastic slider 2 is slidably connected to the upper guide rail of the double circular guide rail 1. Two plastic sliders 2 are slidably connected and installed on the lower guide rail of the double circular guide rail 1. A servo motor 9 is installed on the frame wall of the X-axis support 13. The output end of the servo motor 9 is installed with a transmission wheel A 11. A transmission wheel B 12 is rotatably connected to the frame wall of the X-axis support 13. The space between the track walls of the transmission wheel B 12 and the space between the track walls of the transmission wheel A 11 are connected by a belt 3.
[0026] In use, the double circular guide rail 1 is installed on the X-axis cross beam 10. A plastic slider 2 is slidably connected to the upper guide rail of the double circular guide rail 1, and two plastic sliders 2 are slidably connected to the lower guide rail of the double circular guide rail 1. Then, the three plastic sliders 2 are fixed to the carriage 7 by bolts to complete the connection. The movement accuracy of the carriage 7 is determined by three dimensions of X, Y, and Z. The X direction is the movement direction, the Y direction accuracy is the front and rear clearances between the three sliders and the double circular guide rail 1, and the Z direction accuracy is the upper and lower clearances between the upper and lower guide rails of the double circular guide rail 1 and the plastic slider 2. In theory, it can wobble in the up, down, left, and right ZY directions. However, in reality, due to the gravity eccentricity of the carriage 7 itself, with the lower guide rail of the double circular guide rail 1 on the X direction as the rotation axis, the upper guide rail slider of the double circular guide rail 1 rotates clockwise and is limited, forming a stable YZ space limit, thus achieving a very high installation accuracy. When the heat transfer printer prints, the servo motor 9 drives the belt 3A. Since the rail walls between the transmission wheels A11 and the rail walls of the transmission wheel B12 at the X-axis bracket 13 are connected by the belt 3, after the servo motor 9 drives the transmission wheel A11, the belt 3 rotates. Since the belt 3 is connected to the wall of the carriage 7, and then through the servo motor 9 for motion feedback through the grating scale 4 and the grating decoder 8, the belt 3 pulls the carriage 7 to move back and forth. During the movement, the nozzle 6 sprays ink on the printing medium to ensure the X-axis movement accuracy of the carriage 7. Since the top of the X-axis cross beam 10 and the top of the carriage 7 are connected by a cable carrier 5, the ink pipe and the cable pass through the cable carrier 5, and the cable carrier 5 ensures that the ink pipe and the cable during the movement will not be worn and pulled. Therefore, when the nozzle 6 moves, it moves smoothly and very quietly without adding lubricating oil.
[0027] As Figure 2 and Figure 4 shown, the plastic sliders 2 at the upper guide rail of the double circular guide rail 1 and the plastic sliders 2 at the lower guide rail of the double circular guide rail 1 are both connected to the carriage 7 by bolts.
[0028] In use, the carriage 7 can be limited and moved through the slider.
[0029] As Figure 1 shown, an inkjet hot stamping nozzle 6 is installed at the wall of the carriage 7.
[0030] In use, the nozzle 6 can be connected to an external ink pipe for inkjet hot stamping.
[0031] As Figure 3 shown, a grating decoder 8 is installed at the wall of the carriage 7 by bolts, and the grating decoder 8 is located on one side of the grating scale 4. The grating scale 4 is installed at the outer wall of the X-axis cross beam 10 by bolts.
[0032] In use, through the motion feedback of the grating scale 4 and the grating decoder 8, the stepping direction and distance of the servo motor 9 can be adjusted.
[0033] As Figure 3 shown, the belt 3 is connected to the wall of the trolley frame 7.
[0034] During use, the rotation of the belt 3 can drive the movement of the trolley frame 7.
[0035] As Figure 1 shown, the top of the X-axis crossbeam 10 is connected to the top of the trolley frame 7 by a drag chain 5.
[0036] During use, the ink pipe and cable pass through the drag chain 5, and the drag chain 5 ensures that the ink pipe and cable during movement will not be worn or pulled.
[0037] When the present utility model is in use, the double circular guide rail 1 is installed on the X-axis crossbeam 10. A plastic slider 2 is slidably connected to the upper guide rail of the double circular guide rail 1, and two plastic sliders 2 are slidably connected to the lower guide rail of the double circular guide rail 1. Then the three plastic sliders 2 are fixed to the trolley frame 7 by bolts to complete the connection. The movement accuracy of the trolley frame 7 is determined by three dimensions of X, Y, and Z. The X direction is the movement direction, and the Y direction accuracy is the front and rear clearance between the three sliders and the double circular guide rail 1. The Z direction accuracy is the upper and lower clearance between the upper and lower guide rails of the double circular guide rail 1 and the plastic slider 2. In theory, it can shake in the up, down, left, and right ZY directions. But in fact, due to the gravity eccentricity of the trolley frame 7 itself, with the lower guide rail of the double circular guide rail 1 in the X direction as the rotation axis, the upper guide rail slider of the double circular guide rail 1 rotates clockwise and is limited, forming a stable YZ space limit, so as to achieve a very high installation accuracy. When the heat transfer printer is printing, the servo motor 9 drives the belt 3A. Since the wall between the track walls of the transmission wheel A11 and the wall of the transmission wheel B12 at the X-axis bracket 13 are connected by the belt 3, after the servo motor 9 drives the transmission wheel A11, the belt 3 rotates. Since the belt 3 is connected to the wall of the trolley frame 7, and then through the servo motor 9 for motion feedback through the grating scale 4 and the grating decoder 8, the belt 3 pulls the trolley frame 7 to move back and forth. During the movement, the nozzle 6 sprays ink on the printing medium to ensure the X-axis movement accuracy of the trolley frame 7. Since the top of the X-axis crossbeam 10 is connected to the top of the trolley frame 7 by the drag chain 5, the ink pipe and cable pass through the drag chain 5, and the drag chain 5 ensures that the ink pipe and cable during movement will not be worn or pulled. Thus, when the nozzle 6 moves, it moves smoothly and very quietly without adding lubricating oil.
