[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] like Figures 1 to 5As shown, a coding device for rice noodle packaging bags according to an embodiment of the present invention comprises a conveyor belt 1; a support frame 2 is provided on one side of the conveyor belt 1; a storage box 3 is fixedly connected to the bottom surface of the support frame 2; a pair of closed doors 4 are rotatably connected to the box opening of the storage box 3; a turntable 5 is rotatably connected to the bottom surface inside the storage box 3, and the turntable 5 is driven by a driving assembly; a plurality of uniformly arranged ink tanks 6 are installed on the top surface of the turntable 5; a cover plate 7 is provided on the top surface of the ink tank 6; a clearance groove 8 is provided on the side of the top surface of the cover plate 7 away from the box opening of the storage box 3, and the clearance groove 8 passes through the cover plate 7; a pair of electric push rods 9 are fixedly connected to the top surface inside the storage box 3; the telescopic ends of the electric push rods 9 A cannula 10 is fixedly connected; a nozzle 11 is fixedly connected to the support frame 2 at a position corresponding to the conveyor belt 1, and the nozzle 11 faces the conveyor belt 1; an ink cartridge 12 is fixedly connected to the top of the nozzle 11, and a liquid level sensor is installed in the ink cartridge 12; a conduit 13 is fixedly connected between the ink cartridge 12 and the cannula 10, and the liquid inside the conduit 13 is driven by the pump body; during operation, when continuous coding of packaging bags is required, the embodiment of the present invention can be used. First, the user needs to fill the ink into each ink tank 6, and then the electric push rod 9 pushes the cannula 10 to the give way slot 8, and finally allows the cannula 10 to pass through the give way slot 8 and be inserted into the ink tank 6, and then the pump body pumps the ink in the ink tank 6 through the cannula 10 and the conduit 13 The ink cartridge 12 is then loaded with ink, and the user places the packaging bag to be coded on the conveyor belt 1. When the conveyor belt 1 transports the packaging bag to the support frame 2, the nozzle 11 will spray the pattern required by the user on the surface of the packaging bag. During this period, the ink cartridge 12 draws ink from the ink tank 6 through the conduit 13 to keep the ink in the ink cartridge 12 full. When the liquid level in the ink cartridge 12 drops, it means that the ink in the ink tank 6 has been used up. At this time, the electric push rod 9 will drive the cannula 10 away from the ink tank 6 at the make way slot 8, and then the driving component drives the turntable 5 to rotate, so that the unused ink tank 6 rotates to the bottom of the make way slot 8, and then the electric push rod 9 drives the cannula 10 to be inserted into the ink tank 6, thereby completing the ink printing process. The ink tank 6 can be replaced, and during the replacement process of the ink tank 6, the nozzle 11 always uses the ink in the ink cartridge 12, thereby ensuring that the nozzle 11 can normally complete the coding of the packaging bag. The ink tank 6 is driven to rotate by the turntable 5, and the ink tank 6 at the bottom of the make way slot 8 can be continuously replaced, so that the ink cartridge 12 can always keep ink available. When the ink tank 6 that has run out of ink rotates to the box mouth of the storage box 3, the user can remove it from the turntable 5 and replace it with the ink tank 6 filled with ink, thereby ensuring that the top surface of the rotating disk can always contain the ink tank 6 with ink, and then ensuring that the nozzle 11 can complete the continuous coding of the packaging bag, so as to avoid the problem of reduced production efficiency due to the addition of ink.

[0034] like Figure 5As shown, a sealing plate 14 is fixedly connected to the surface of the insert tube 10; the sealing plate 14 is arranged in an annular structure; a sealing gasket 15 is fixedly connected to the bottom surface of the sealing plate 14, and the sealing gasket 15 is arranged in an annular shape; an annular plate 16 is fixedly connected to the bottom surface of the sealing plate 14 and the inner side of the sealing gasket 15; the diameter of the bottom of the sealing gasket 15 is smaller than the diameter of its top; during operation, when the electric push rod 9 drives the insert tube 10 to be inserted into the ink tank 6, the sealing plate 14 will also follow the insert tube 10 to be inserted into the ink tank 6, and finally cover the tank mouth of the ink tank 6, at this time, the sealing gasket 15 at the bottom of the sealing plate 14 will be inserted into the interior of the ink tank 6, and the annular plate 16 cooperates with the tank mouth of the ink tank 6 to clamp the sealing gasket 15 between the annular plate 16 and the tank mouth of the ink tank 6, thereby ensuring the sealing of the ink tank 6 during use, and preventing the ink in the ink tank 6 from being exposed to the outside air for a long time, which causes the ink to dry up and affects the subsequent normal use.

[0035] like Figure 2 , Figure 4 , Figure 6 and Figure 7As shown, the driving assembly includes a rotating column 17; the rotating column 17 is rotatably connected to the bottom surface of the storage box 3 and is driven by a servo motor; the bottom surface of the turntable 5 is rotatably connected to a sleeve 18; the sleeve 18 is rotatably connected to the inner wall of the storage box, and the rotating column 17 is fixedly connected to the inner wall of the sleeve 18; the bottom surface of the turntable 5 is fixedly connected to a baffle 19; the surface of the rotating column 17 is fixedly connected to a paddle 20; the side surface of the sleeve 18 is fixedly connected to a main gear 21; the bottom surface of the storage box 3 is rotatably connected to rotating rods 22 on both sides of the turntable 5; the surface of the rotating rod 22 is fixedly connected to the inner wall of the sleeve 18 A one-way bearing 23 is connected, and the two one-way bearings 23 are rotatable in opposite directions; the surfaces of the two one-way bearings 23 are respectively fixedly connected with a gear 1 24 and a gear 2 25; the gear 1 24 and the gear 2 25 are respectively meshed and connected with the main gear 21, and the gear ratio of the gear 1 24 to the gear 2 25 is 1:2; the top surfaces of the two rotating rods 22 are both fixedly connected with a threaded rod 26, and the two threaded rods 26 are driven by a top chain; the two sides of the cover plate 7 are fixedly connected with a connecting plate 27 at the corresponding positions of the threaded rod 26; the connecting plate 27 is threadedly connected with the threaded rod 26;During operation, before the driving assembly drives the turntable 5 to rotate, a certain distance is left between the paddle 20 on the surface of the rotating column 17 and the baffle 19, and the angle formed by the line from the baffle 19 to the center of the rotating column 17 and then to the paddle 20 is the same as the angle formed by the line from the adjacent ink tank 6 to the center of the rotating column 17. The angle here is recorded as α. Then the servo motor drives the paddle 20 to rotate α degrees. At this time, the paddle 20 is just in contact with the surface of the baffle 19. When the rotating column 17 drives the paddle 20 to rotate α degrees, it also drives the sleeve 18 and the main gear 21 on its surface to rotate. Then the main gear 21 drives the gear 1 24 and the gear 2 25 to rotate. At this time, the one-way bearing 23 at the gear 2 25 can rotate in the opposite direction to the current rotation direction of the gear 2 25. , so gear 25 can drive the rotating rod 22 to rotate, and the one-way bearing 23 at gear 1 24 has the same rotation direction as the current rotation direction of gear 1 24, so gear 1 24 will rotate relative to the rotating rod 22, that is, gear 1 24 will not drive the rotating rod 22 located on its own side to rotate, and because the threaded rod 26 on the top surface of the rotating rod 22 is connected by a chain, at this time, gear 25 drives the two threaded rods 26 to rotate synchronously through the rotating rod 22 and the chain, and then the rotation of the threaded rod 26 drives the connecting plate 27 and the cover plate 7 to rise, so that the cover plate 7 is separated from the top surface of the ink tank 6, and then the servo motor continues to drive the dial plate 20 to rotate α degrees according to the previous rotation direction. At this time, the dial plate 20 will drive the baffle 19, the turntable 5 and the sleeve 18 rotates synchronously by α degrees, so that the ink tank 6 adjacent to the make way slot 8 can be rotated to the bottom of the make way slot 8 to complete the replacement of the empty ink tank 6, and then the servo motor drives the rotating column 17 to rotate α degrees in the opposite direction as before. During this process, the paddle 20 will be away from the baffle 19, so the turntable 5 will no longer rotate, but the sleeve 18 can normally follow the rotating column 17 to rotate, thereby the sleeve 18 will drive the main gear 21 to rotate α degrees in the opposite direction as before, and then the main gear 21 drives the gear 1 24 and the gear 2 25 to rotate, but the rotation direction at this time is opposite to the previous rotation direction, so the gear 2 25 can no longer drive the rotating rod 22 to rotate, while the gear 1 24 can drive the rotating rod 22 to rotate, thereby causing the threaded rod 26 to rotate in the opposite direction as before, As a result, the cover plate 7 is lowered. Since the gear ratio of gear 1 24 and gear 2 25 is 1:2, the number of turns of gear 2 25 when the main gear 21 rotates 2α degrees is consistent with the number of turns of gear 1 24 when the main gear 21 rotates α degrees, thereby ensuring that the height of the cover plate 7 driven by the threaded rod 26 is consistent, thereby ensuring that the cover plate 7 can be covered back on the top surface of the ink tank 6. Through the cooperation of the rotating column 17, the paddle 20, the baffle 19, the main gear 21, the gear 1 24, the gear 25, the one-way bearing 23, the rotating column 17 and the threaded rod 26, the cover plate 7 can first rise and move away from the ink tank 6 before the turntable 5 drives the ink tank 6 to rotate, thereby avoiding friction between the cover plate 7 and the ink tank 6, thereby causing wear and rotation obstruction of the ink tank 6. ;

[0036] like Figure 3 and Figure 8 As shown, a pair of arc plates 28 are fixedly connected to the bottom surface of the cover plate 7, and the two arc plates 28 are symmetrical about the clearance groove 8; the ink tank 6 is located between the two arc plates 28; the surface of the arc plate 28 is rotatably connected with a plurality of evenly arranged rollers 29; during operation, when the turntable 5 drives the ink tank 6 to rotate, the surface of the ink tank 6 can contact the rollers 29 on the surface of the arc plate 28, so that the ink tank 6 can be limited by the rollers 29, thereby preventing the ink tank 6 from deviating from its original position due to centrifugal action when rotating. At the same time, when the ink tank 6 moves relatively between the rollers 29, the rollers 29 will also rotate, thereby reducing the friction force of the ink tank 6 when moving, thereby reducing the wear on the ink tank 6 and increasing its service life.

[0037] like Figure 8 As shown, the bottom surface of the cover plate 7 is fixedly connected with a rubber plug 30 at the corresponding position of the ink tank 6; the rubber plug 30 is arranged in an arc shape, and the diameter of the end of the rubber plug 30 close to the cover plate 7 is larger than the diameter of the mouth of the ink tank 6; when working, when the cover plate 7 covers the top surface of the ink tank 6, the rubber plug 30 on the bottom surface of the cover plate 7 will be inserted into the mouth of the ink tank 6, thereby further improving the sealing performance of the ink tank 6, and preventing the ink in the ink tank 6 from being solidified due to long-term contact with the air. At the same time, when the threaded rod 26 drives the cover plate 7 to rise, the rubber plug 30 will also be pulled out of the ink tank 6, thereby preventing the rubber plug 30 from interfering with the rotation of the ink tank 6.

[0038] like Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, the surface of the turntable 5 is provided with a receiving groove 31 at the corresponding position of the ink tank 6; a fixing seat 32 is arranged in the receiving groove 31; the top surface of the fixing seat 32 is fixedly connected to a limiting plate 33; the limiting plate 33 is arranged in an arc shape and is adapted to the bottom of the ink tank 6; the end of the fixing seat 32 away from the center of the turntable 5 is fixedly connected with a screw rod 34; the screw rod 34 passes through the fixing seat 32 and is threadedly connected to the groove wall of the receiving groove 31; the two ends of the limiting plate 33 are commonly fixedly connected with an elastic band 35; during operation, when the user replaces the empty ink tank 6, the user needs to screw the screw rod 34 at the end of the fixing seat 32, so that the fixing seat The fixing between the fixing seat 32 and the inner wall of the receiving groove 31 is released, and then the fixing seat 32 is placed on the bottom of the receiving groove 31 so that the top of the ink tank 6 is separated from the rubber plug 30. In this way, the user can pull the fixing seat 32 and the ink tank 6 out of the receiving groove 31, and then pull the ink tank 6 out from between the limiting plate 33 and the elastic band 35, and replace the ink tank 6 filled with ink, and then reinsert it into the receiving groove 31 and fix it with the screw 34, thereby facilitating the user to replace the ink tank 6. At the same time, the cooperation of the limiting plate 33 and the elastic band 35 can also fix the ink tank 6 to prevent the ink tank 6 from detaching from the surface of the fixing seat 32 during the replacement process.

[0039] like Figure 3 , Figure 4 and Fig. 9 As shown, a base 36 is fixedly connected to the bottom surface of the storage box 3 and one side close to the box opening of the storage box 3; an extension plate 37 is slidably connected to the top surface of the base 36; a receiving box 38 is slidably connected to the top surface of the extension plate 37, and the receiving box 38 is adapted to the fixed seat 32; during operation, after the user releases the fixation between the fixed seat 32 and the accommodating groove 31, the user can also place the fixed seat 32 on the receiving box 38, and then pull the receiving box 38 to make the receiving box 38 slide on the extension plate 37, driving the ink tank 6 to move toward the box opening of the storage box 3, and when the receiving box 38 moves to the end of the extension plate 37, the receiving box 38 will drive the extension plate 37 to slide on the base 36, so that the receiving box 38 and the ink tank 6 are completely moved to the outside of the storage box 3, thereby the ink tank 6 can be replaced outside the storage box 3 while having the receiving box 38 as a support, thereby obtaining a larger operating space and better lighting conditions, reducing the difficulty of replacement for the user.

[0040] like Fig. 9As shown, the side of the receiving box 38 away from the turntable 5 is fixedly connected with a traction rod 39 that is slidably connected; the side of the traction rod 39 close to the screw 34 is fixedly connected with a magnet block 40; the screw 34 is made of a magnetizable metal material; during operation, when it is necessary to move the fixed seat 32 to the top surface of the receiving box 38, the user can move the traction rod 39 so that the magnet block 40 at the end of the traction rod 39 adsorbs the end of the threaded rod 26, and then the user can pull the traction rod 39 to pull the screw 34 and the fixed seat 32 to the top surface of the receiving box 38, and the traction rod 39 can also be used as a handle for the user to pull the receiving box 38, thereby further facilitating the use of the user.

[0041] like Figures 9 and 10 As shown, the top surface of the base 36 is provided with a strip groove 41; the bottom surface of the extension plate 37 is fixedly connected with a tooth plate 42 in the strip groove 41, and teeth are provided on both sides of the tooth plate 42; a pair of gears 43 are rotatably connected at the box opening of the storage box 3; the two gears 43 are symmetrical about the tooth plate 42, and the gears 43 can mesh with the tooth plate 42; the two gears 43 are meshed and connected with gears 44 on the sides away from each other, and the gears 44 are rotatably connected to the outer wall of the storage box 3; the bottom surface of the gear 44 is fixedly connected with a support plate 45; when working, when When the extension plate 37 slides toward the box opening of the storage box 3, the two sides of the tooth plate 42 will mesh with the two gear threes 43, and then the gear three 43 will drive the gear four 44 to rotate, and the gear four 44 will drive the support plate 45 to rotate, eventually making the two support plates 45 rotate towards each other and perpendicular to the outer wall of the storage box 3, so that the support plate 45 can support the receiving box 38, preventing the ink tank 6 and the receiving box 38 from extending out of the storage box 3, causing the extension plate 37 to be deformed due to the force on one end, thereby causing the extension plate 37 to be unable to slide normally on the base 36.

[0042] like Fig. 9 As shown, the outer wall of the storage box 3 is fixedly connected to a limit seat 46 at a corresponding position of the support plate 45; the limit seat 46 is L-shaped and made of a magnet; the support plate 45 is made of a magnetizable metal; during operation, when the extension plate 37 is retracted to the interior of the storage box 3, the tooth plate 42 will drive the support plate 45 to rotate toward the limit seat 46, so that the bottom of the support arm is placed on the horizontal part of the limit seat 46, and since the limit seat 46 is made of a magnet and the support plate 45 is made of a magnetizable metal, the limit seat 46 will absorb the support plate 45 to prevent the support plate 45 from rotating at will, thereby ensuring that when the tooth plate 42 extends out of the storage box 3, the tooth plate 42 can engage with the gear three 43 normally.

[0043] During operation, when it is necessary to continuously inkjet the packaging bag, the embodiment of the present invention can be used. First, the user needs to fill the ink into each ink tank 6, and then the electric push rod 9 pushes the cannula 10 to the give way slot 8, and finally allows the cannula 10 to pass through the give way slot 8 and be inserted into the ink tank 6. Then the pump body draws the ink in the ink tank 6 into the ink cartridge 12 through the cannula 10 and the conduit 13. Then the user places the packaging bag to be coded on the conveyor belt 1. When the conveyor belt 1 transports the packaging bag to the support frame 2, the nozzle 11 will spray the pattern required by the user on the surface of the packaging bag. During this period, the ink cartridge 12 sucks the ink in the ink tank 6 through the conduit 13 to keep the ink in the ink cartridge 12 full. When the liquid level in the ink cartridge 12 drops, it means that the ink in the ink tank 6 has been used up. At this time, the electric push rod 9 will drive the cannula 10 away from the ink tank 6 at the give way slot 8, and then drive The movable assembly drives the turntable 5 to rotate, so that the unused ink tank 6 rotates to the bottom of the make way slot 8, and then the electric push rod 9 drives the cannula 10 to be inserted into the ink tank 6, thereby completing the replacement of the ink tank 6. During the replacement of the ink tank 6, the nozzle 11 always uses the ink in the ink cartridge 12, thereby ensuring that the nozzle 11 can normally complete the coding of the packaging bag. By driving the ink tank 6 to rotate by the turntable 5, the ink tank 6 at the bottom of the make way slot 8 can be continuously replaced, so that the ink cartridge 12 can always keep ink available. When the ink tank 6 that has run out of ink rotates to the box mouth of the storage box 3, the user can remove it from the turntable 5 and replace it with the ink tank 6 filled with ink, thereby ensuring that the top surface of the rotating disk can always contain the ink tank 6 with ink, and then ensuring that the nozzle 11 can complete the continuous coding of the packaging bag, so as to avoid the problem of reduced production efficiency due to the addition of ink.

[0044] When the electric push rod 9 drives the insertion tube 10 to be inserted into the ink tank 6, the sealing plate 14 will also follow the insertion tube 10 to be inserted into the ink tank 6, and finally cover the tank mouth of the ink tank 6. At this time, the sealing gasket 15 at the bottom of the sealing plate 14 will be inserted into the ink tank 6, and the sealing gasket 15 will be clamped between the annular plate 16 and the tank mouth of the ink tank 6 through the cooperation of the annular plate 16 and the tank mouth of the ink tank 6, so as to ensure the sealing of the ink tank 6 when in use, and prevent the ink in the ink tank 6 from being exposed to the outside air for a long time, which will cause the ink to dry up and affect the subsequent normal use.

[0045] Before the driving assembly drives the turntable 5 to rotate, a certain distance is left between the paddle 20 on the surface of the rotating column 17 and the baffle 19, and the angle formed by the line from the baffle 19 to the center of the rotating column 17 and then to the paddle 20 is the same as the angle formed by the line from the adjacent ink tank 6 to the center of the rotating column 17. The angle here is recorded as α. Then the servo motor drives the paddle 20 to rotate α degrees. At this time, the paddle 20 is just in contact with the surface of the baffle 19. When the rotating column 17 drives the paddle 20 to rotate α degrees, it also drives the sleeve 18 and the main gear 21 on its surface to rotate. Then the main gear 21 drives the gear 1 24 and the gear 2 25 to rotate. At this time, the one-way bearing 23 at the gear 2 25 can rotate in the opposite direction to the current rotation direction of the gear 2 25. Therefore, Gear 2 25 can drive the rotating rod 22 to rotate, and the one-way bearing 23 at gear 1 24 has the same rotation direction as the current gear 1 24, so gear 1 24 will rotate relative to the rotating rod 22, that is, gear 1 24 will not drive the rotating rod 22 located on its own side to rotate, and because the threaded rod 26 on the top surface of the rotating rod 22 is connected by a chain, at this time, gear 25 drives the two threaded rods 26 to rotate synchronously through the rotating rod 22 and the chain, and then the rotation of the threaded rod 26 drives the connecting plate 27 and the cover plate 7 to rise, so that the cover plate 7 is separated from the top surface of the ink tank 6, and then the servo motor continues to drive the dial plate 20 to rotate α degrees according to the previous rotation direction. At this time, the dial plate 20 will drive the baffle 19, the turntable 5 and the sleeve 18 The ink tank 6 adjacent to the make way slot 8 is rotated synchronously by α degrees, so that the ink tank 6 can be rotated to the bottom of the make way slot 8 to complete the replacement of the empty ink tank 6, and then the servo motor drives the rotating column 17 to rotate α degrees in the opposite direction as before. During this process, the paddle 20 will be away from the baffle 19, so the turntable 5 will no longer rotate, but the sleeve 18 can normally follow the rotating column 17 to rotate, thereby the sleeve 18 will drive the main gear 21 to rotate α degrees in the opposite direction as before, and then the main gear 21 drives the gear 1 24 and the gear 2 25 to rotate, but the rotation direction at this time is opposite to the previous rotation direction, so the gear 2 25 can no longer drive the rotating rod 22 to rotate, while the gear 1 24 can drive the rotating rod 22 to rotate, thereby causing the threaded rod 26 to rotate in the opposite direction as before, The cover plate 7 is lowered. Since the gear ratio of gear 1 24 and gear 2 25 is 1:2, the number of turns of gear 2 25 when the main gear 21 rotates 2α degrees is consistent with the number of turns of gear 1 24 when the main gear 21 rotates α degrees, thereby ensuring that the height of the cover plate 7 driven by the threaded rod 26 to rise and fall is consistent, thereby ensuring that the cover plate 7 can be returned to the top surface of the ink tank 6. Through the cooperation of the rotating column 17, the paddle 20, the baffle 19, the main gear 21, gear 1 24, the gear 25, the one-way bearing 23, the rotating column 17 and the threaded rod 26, the cover plate 7 can first rise and move away from the ink tank 6 before the turntable 5 drives the ink tank 6 to rotate, thereby avoiding friction between the cover plate 7 and the ink tank 6, thereby causing wear and rotation obstruction of the ink tank 6.

[0046] When the turntable 5 drives the ink tank 6 to rotate, the surface of the ink tank 6 can contact the roller 29 on the surface of the arc plate 28, so that the ink tank 6 can be limited by the roller 29, thereby preventing the ink tank 6 from deviating from its original position due to the centrifugal effect when rotating. At the same time, when the ink tank 6 moves relatively between the rollers 29, the rollers 29 will also rotate, thereby reducing the friction force of the ink tank 6 when moving, thereby reducing the wear on the ink tank 6 and increasing its service life.

[0047] When the cover plate 7 is covered on the top surface of the ink tank 6, the rubber plug 30 on the bottom surface of the cover plate 7 will be inserted into the mouth of the ink tank 6, thereby further improving the sealing of the ink tank 6 and preventing the ink in the ink tank 6 from solidifying due to long-term contact with air. At the same time, when the threaded rod 26 drives the cover plate 7 to rise, the rubber plug 30 will also be pulled out of the ink tank 6, thereby preventing the rubber plug 30 from interfering with the rotation of the ink tank 6.

[0048] When the user replaces the empty ink tank 6, the user needs to screw the screw 34 at the end of the fixing seat 32 to release the fixing between the fixing seat 32 and the inner wall of the receiving groove 31, and then place the fixing seat 32 on the bottom of the receiving groove 31 to make the top of the ink tank 6 separate from the rubber plug 30. In this way, the user can pull the fixing seat 32 and the ink tank 6 out of the receiving groove 31, and then pull the ink tank 6 out from between the limiting plate 33 and the elastic band 35, and replace it with the ink tank 6 filled with ink, and then reinsert it into the receiving groove 31 and fix it with the screw 34, thereby facilitating the user to replace the ink tank 6. At the same time, the cooperation of the limiting plate 33 and the elastic band 35 can also fix the ink tank 6 to prevent the ink tank 6 from detaching from the surface of the fixing seat 32 during the replacement process.

[0049] When the user releases the fixation between the fixing seat 32 and the accommodating groove 31, the user can also place the fixing seat 32 on the receiving box 38, and then pull the receiving box 38 to make the receiving box 38 slide on the extension plate 37, driving the ink tank 6 to move toward the box opening of the storage box 3. When the receiving box 38 moves to the end of the extension plate 37, the receiving box 38 will drive the extension plate 37 to slide on the base 36, so that the receiving box 38 and the ink tank 6 are completely moved to the outside of the storage box 3. In this way, the ink tank 6 can be replaced outside the storage box 3 while having the receiving box 38 as a support, thereby obtaining a larger operating space and better lighting conditions, reducing the difficulty of replacement for the user.

[0050] When it is necessary to move the fixing seat 32 to the top surface of the receiving box 38, the user can move the traction rod 39 so that the magnet block 40 at the end of the traction rod 39 adsorbs the end of the threaded rod 26. At this time, the user can pull the traction rod 39 to pull the screw rod 34 and the fixing seat 32 to the top surface of the receiving box 38, and the traction rod 39 can also serve as a handle for the user to pull the receiving box 38, thereby further facilitating the user's use.

[0051] When the extension plate 37 slides toward the box opening of the storage box 3, the two sides of the tooth plate 42 will mesh with the two gear threes 43, and then the gear three 43 will drive the gear four 44 to rotate, and the gear four 44 will drive the support plate 45 to rotate, eventually making the two support plates 45 rotate towards each other and perpendicular to the outer wall of the storage box 3, so that the support plate 45 can support the receiving box 38, preventing the ink tank 6 and the receiving box 38 from extending out of the storage box 3, causing the extension plate 37 to be deformed due to the force on one end, thereby causing the extension plate 37 to be unable to slide normally on the base 36.

[0052] When the extension plate 37 is retracted into the storage box 3, the tooth plate 42 will drive the support plate 45 to rotate toward the limit seat 46, so that the bottom of the support arm is placed on the horizontal part of the limit seat 46. Since the limit seat 46 is made of a magnet and the support plate 45 is made of a magnetizable metal, the limit seat 46 will absorb the support plate 45 to prevent the support plate 45 from rotating at will, thereby ensuring that the tooth plate 42 can engage with the gear three 43 normally when the tooth plate 42 extends out of the storage box 3.
