Description

Technical Field

[0001] The utility model belongs to the technical field of printers, and particularly relates to a lifting ink stack structure. Background Art

[0002] The ink stack is a mechanism used to hold the nozzle on the inkjet printer. When the inkjet printer stops working, the nozzle will be placed on the ink stack. On the one hand, the ink stack can keep the nozzle moist to prevent the nozzle from being blocked. On the other hand, it can absorb and clean the residual ink on the inkjet head to prevent the ink from polluting the environment. In order to achieve the docking between the ink stack and the nozzle, the existing ink stack structure generally has a lifting function, and the traditional lifting ink stack structure mainly adopts cylinder-driven lifting, that is, the ink stack bearing platform is directly lifted by the output shaft of the cylinder. This lifting ink stack structure has low lifting accuracy and poor stability. The ink stack bearing platform is prone to shaking or tilting, resulting in the inability of the ink stack and the nozzle to fully contact and seal, affecting the moisturizing and cleaning effects.

[0043] Embodiment

[0044] Referring to Figures 1-3 , a lifting ink stack structure for being installed on an inkjet printer table, comprising two fixing plates 1, a lead screw motor 2 and a lifting assembly 3;

[0045] The two fixing plates 1 are fixed on the table; the lead screw motor 2 is fixed on the table and is located between the two fixing plates 1; the lifting assembly 3 is arranged between the two fixing plates 1;

[0046] The lifting assembly 3 includes two connecting plates 31, a bearing platform 32, a plurality of ink stack caps 33, a support plate 34 and two support rods 35;

[0047] The two connecting plates 31 are respectively connected to the fixing plates 1 on both sides through slide rails 36; the bearing platform 32 is fixed on the tops of the two connecting plates 31; a plurality of ink stack caps 33 are fixed on the top of the bearing platform 32; the support plate 34 is fixed between the upper parts of the two connecting plates 31 and is connected to the lead screw motor 2 at the bottom and is driven to lift by the lead screw motor 2; the two support rods 35 are fixed between the lower parts of the two connecting plates 31.

[0048] When this lifting ink stack structure is specifically applied, after the inkjet printer pauses printing, the printhead carriage 100 automatically moves to the corresponding position directly above this lifting ink stack structure, and the lead screw motor 2 is started. The lead screw motor 2 drives the support plate 34 to rise, thereby driving the entire lifting assembly 3 to rise along the slide rail 36 until the ink stack cap 33 is in full contact with the printhead of the inkjet printer for sealing, and the printhead can be moisturized and cleaned.

[0049] The lifting assembly 3 of this lifting ink stack structure is driven to lift by the lead screw motor 2. Compared with the traditional cylinder drive, the lifting precision is higher. The two connecting plates 31 are respectively connected to the fixed plates 1 on both sides through the slide rails 36. Through the slide rails 36, the overall stability of the lifting assembly 3 can be ensured, and the lifting assembly 3 can be effectively prevented from shaking or tilting, ensuring that the ink stack cap 33 and the printhead can be in full contact for sealing, thereby improving the moisturizing and cleaning effects. The support plate 34 is fixed between the upper parts of the two connecting plates 31, and the two support rods 35 are fixed between the lower parts of the two connecting plates 31. The two connecting plates 31 are supported by the support plate 34 and the two support rods 35, and the two connecting plates 31 can be effectively prevented from deforming, further ensuring the overall stability of the lifting assembly 3.

[0050] In a specific implementation, the lead screw motor 2 includes a motor body 21, a lead screw 22, and a nut 23;

[0051] The motor body 21 is fixed to the machine table through a bracket 24, and the two support rods 35 are located on both sides of the bracket 24, one in front and the other behind; the lead screw 22 is fixedly connected to the output shaft of the motor body 21 through a coupling 25; the nut 23 is threadedly sleeved on the lead screw 22 and is fixedly connected to the support plate 34.

[0052] When the motor body 21 rotates, its output shaft drives the lead screw 22 to rotate through the coupling 25. After the lead screw 22 rotates, the nut 23 can reciprocate up and down on the lead screw 22, thereby driving the lifting assembly 3 to perform a lifting motion.

[0053] In a specific implementation, the slide rail 36 is a common connecting component. The slide rail 36 includes a guide rail 361 and a slider 362 that are slidably engaged with each other. The guide rail 361 is fixedly connected to the fixed plate 1, and the slider 362 is fixedly connected to the connecting plate 31.

[0054] In a specific implementation, the carrying platform 32 includes a receiving box 321 and a carrying plate 322;

[0055] The accommodation box 321 is fixed on the tops of the two connecting plates 31, and a pipe joint 3211 is provided at its bottom; the bearing plate 322 is fixed in the accommodation box 321 through a support column. A plurality of fine holes are provided on the bearing plate 322, and a plurality of ink stack caps 33 are fixed on the top of the bearing plate 322.

[0056] During operation, the waste ink overflowing from the ink stack cap 33 can flow into the accommodation box 321 through the fine holes. The accommodation box 321 accumulates the waste ink and can discharge the waste ink through the pipe joint 3211 connecting to an ink pipe, so that the inside of the machine can be kept clean.

[0057] In a specific embodiment, a first upper limit component is further included. The first upper limit component includes a first upper limit switch 41, a T-shaped guide rod 42, and a compression spring 43.

[0058] The first upper limit switch 41 is fixed on the front side of the support plate 34; the T-shaped guide rod 42 is movably inserted through the bearing platform 32; the compression spring 43 is sleeved on the T-shaped guide rod and is located between the top of the T-shaped guide rod 42 and the bearing platform 32.

[0059] During the process of the screw motor 2 driving the lifting component 3 to rise, after the top of the T-shaped guide rod 42 contacts the nozzle carriage 100, the nozzle carriage squeezes the T-shaped guide rod 42 to move downward. When the T-shaped guide rod 42 contacts the first upper limit switch 41, the docking of the ink stack cap 33 with the nozzle is completed, and a signal is sent to stop the screw motor 2 from moving.

[0060] In a specific embodiment, a second upper limit component is further included. The second upper limit component includes a second upper limit switch 51 and an upper limit probe 52.

[0061] The second upper limit switch 51 is fixed on the front side of the fixed plate 1; the upper limit probe 52 is fixed on the front side of the connecting plate 31.

[0062] In the present utility model, the first upper limit component serves as the main limit, and the second upper limit component serves as the secondary limit. When the first upper limit component fails and the screw motor 2 cannot be stopped after the T-shaped guide rod 42 contacts the first upper limit switch 41, the lifting component 3 continues to rise until the upper limit probe 52 contacts the second upper limit switch 51, and a signal is sent to stop the screw motor 2 from moving. In this way, the lifting component 3 can be prevented from colliding with the nozzle carriage, protecting the safety of the equipment.

[0063] In a specific embodiment, a lower limit switch 6 is further included, and the lower limit switch 6 is fixed on the front side of the fixed plate 1.

[0064] When the inkjet printer resumes printing work, the lead screw motor 2 drives the lifting assembly 3 to descend. When the bearing platform 32 contacts the lower limit switch 6, it indicates that the original position has been reached, and the lead screw motor 2 stops moving.

[0065] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
