Description

Technical Field

[0001] The invention belongs to the technical field of inkjet printing, and in particular relates to an ink cartridge suspension-type shock-absorbing structure with multi-directional buffering support. Background Art

[0002] Ink cartridges are the core consumables used in printers to store and release ink. Their function is to form text or images by precisely controlling the spraying of ink onto paper. When assembled in a printer, ink cartridges are usually installed on a support structure and follow the movement to perform inkjet printing.

[0003] The prior art ink cartridge suspension-type shock-absorbing structure used for support usually adopts a connection combination of elastic materials after the ink cartridge is assembled to achieve a certain degree of buffering and shock absorption. However, in actual use, due to the instantaneous start and stop of the support structure, there is inertia during the instantaneous start and stop stage, which causes the elastic mechanism to vibrate repeatedly in the support structure when the support structure starts and stops. Although the prior art has performed elastic buffering treatment to deal with inertia, the elastic buffering causes the ink cartridge to vibrate elastically within a certain range, causing the internal ink to be agitated and easily generate bubbles inside the ink cartridge. The bubbles will burst again due to the vibration and become more small bubbles, thereby hindering the normal ejection of ink, affecting the continuity of the print head printing, causing uneven printing and missing printing, reducing printing accuracy, and poor printing effect.

[0014] The beneficial effects of the present invention are as follows: 1. The present invention utilizes a multi-directional elastic mechanism arranged on the outside of the inner frame, combined with a magnetic buffer mechanism arranged on the inner frame and the main frame. When the shock-absorbing structure drives the ink cartridge fixed inside to start and stop instantaneously, on the one hand, the multi-directional elastic mechanism is used to absorb and buffer the inertial force. On the other hand, combined with the inertial action, the magnetic repulsive force in the direction of inertial displacement is automatically enhanced. While elastically buffering, the inner frame and the ink cartridge fixed inside are pushed in the reverse direction to overcome the inertial trend and maintain reset stability, thereby realizing inertial buffering and inertial resistance in the instantaneous movement start and stop stage of the ink cartridge, reducing the disturbance of the ink cartridge under the action of inertia, maintaining the stability of the internal ink, avoiding the generation of a large number of bubbles due to inertial agitation and affecting printing continuity, and ensuring the printing quality and achieving rapid stabilization after inertial buffering.

[0015] 2. The present invention utilizes a buffer compensation component on the outside of the main frame. On the one hand, the buffer compensation component is used to achieve collision buffering on the outside to reduce collision damage. On the other hand, when the ink cartridge follows the main frame to move to the set boundary and drifts beyond the set position, the collision and extrusion between the buffer compensation component and the rigid structure of the set boundary is utilized to quickly and automatically release the aforementioned magnetic buffer mechanism on the outside of the inner frame, and the actual drift amount is reflected according to the collision buffer extrusion amount. The collision buffer extrusion effect causes the inner frame to move in a specified direction, and the displacement amount is consistent with the drift amount. Therefore, when the main frame drifts beyond the set boundary, the internal frame drives the ink cartridge to compensate for the displacement, ensuring that the ink cartridge position is maintained at the set boundary position, and completing precise inkjet printing at the set boundary position, avoiding inkjet printing deviation caused by the ink cartridge following drift during boundary drift, and ensuring printing quality.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] like Figures 1 to 8 As shown, an embodiment of the present invention provides a cartridge suspension shock-absorbing structure with multi-directional buffer support, comprising a main frame 1, an inner frame 2 is provided inside the main frame 1, the inner frame 2 is elastically connected to the main frame 1 through a multi-directional elastic mechanism, a magnetic buffer mechanism is provided between the main frame 1 and the inner frame 2, the internal array of the inner frame 2 is provided with an elastic assembly ring 6, the outer side of the inner frame 2 is provided with an adsorption fixing mechanism 7, the adsorption fixing mechanism 7 is connected to the elastic assembly ring 6, and buffer compensation components 14 are also provided on both sides of the main frame 1, and a magnetic plate 8 is fixed on the outer side of the adsorption fixing mechanism 7, the magnetic buffer mechanism comprises a main touch plate 9, a sensing part 10 and an electromagnet 13, the main touch plate 9 is symmetrically arranged on both sides of the inner frame 2, the sensing part 10 is nested on the inner wall of the main frame 1, the electromagnet 13 array is distributed on the outer side of the magnetic plate 8, the sensing part 10 senses the main touch plate 9 that slides on the outer side, and controls the starting number of the electromagnet 13 according to the contact area between the main touch plate 9 and the sensing part 10, thereby changing the repulsive force of the electromagnet 13 on the magnetic plate 8.

[0020] Example 1: During use, the ink cartridge is sleeved in the inner ring body 61 of the elastic assembly ring 6, and the elastic inner ring body 61 is used to complete the damping stabilization after sleeve installation, and the electric push rod 72 in the adsorption and fixing mechanism 7 is started to drive the movable plug 73 to move along the side frame 71, and suck the air in the internal communication cavity 74 in the connected inner frame 2, so that a low-pressure space is formed inside the internal communication cavity 74, and the elastic assembly ring 6 is used to connect. When the vent 62 is blocked by the ink cartridge, the ink cartridge is adsorbed and fixed by the negative pressure effect, and the ink cartridge is stably adsorbed and fixed inside the elastic assembly ring 6 to complete the fixing process. Because the printer itself is equipped with a fan for forming a negative pressure state on the cardboard conveying surface, it just uses the fan to perform negative pressure adsorption and fixation on the ink cartridge. When the shock-absorbing structure drives the internal ink cartridge to move quickly, the ink cartridge is delayed by the inertia of the inner frame 2 under the action of inertia, causing a position offset between the inner frame 2 and the main frame 1, and as the relative offset action occurs, the main touch plates 9 on both sides of the inner frame 2 slide relatively in the main frame 1, and the main touch plate 9 on one side slides along the surface of the contact sensing part 10 and gradually increases the contact area, and compresses the spring 3 on the corresponding side, while the main touch plate 9 on the other side displaces along the contact sensing part 10 and reduces the contact area, and at the same time stretches the spring 3 on the corresponding side to achieve inertial buffering, and as the main touch plate 9 moves relative to the corresponding sensing part 10, when the contact area changes, the capacitive sensing part 10 senses the capacitance change, and receives the circuit change signal through the external control terminal and controls the activation number of the electromagnet 13, so that the activation number of the electromagnet 13 on the side with increased contact area increases, and the contact area decreases. The number of electromagnets 13 started on the smaller side is reduced, so the total magnetic force generated by the electromagnets 13 on the side with more started numbers is increased, and an enhanced repulsive force is generated on the magnetic plate 8 on the corresponding side of the inner frame 2 that is gradually approaching, and the inner frame 2 with inertial displacement is pushed in the opposite direction, and reset in the direction of following the movement of the main frame 1, so that when the main frame 1 actively displaces and causes the inner frame 2 and the ink cartridge to inertially deviate, the springs 13 on both sides are used for elastic buffering, while increasing the magnetic repulsive force in the relative displacement direction, and pushing the elastic buffered inner frame 2 and the ink cartridge to reset quickly at the same time, and the ink cartridge completes the elastic buffering and magnetic power reset at the same time during the sudden start and stop stage, the inertial effect is weakened, and the ink agitation phenomenon inside the ink cartridge is reduced; when the shock-absorbing structure vibrates up and down, the inner frame 2 and the fixed ink cartridge absorb the vibration potential energy and maintain stability under the combined action of the elastic action of the upper and lower springs 24 and the damping of the end damping layer 11.

[0021] First, by utilizing a multi-directional elastic mechanism arranged on the outside of the inner frame 2, combined with a magnetic buffer mechanism arranged on the inner frame 2 and the main frame 1, when the shock-absorbing structure drives the internally installed fixed ink cartridge to start and stop instantaneously, on the one hand, the multi-directional elastic mechanism is utilized to absorb and buffer the inertial force, and on the other hand, combined with the inertial action, by automatically enhancing the magnetic repulsive force in the inertial displacement direction, while elastically buffering, the inner frame 2 together with the internally fixed ink cartridge is pushed in reverse to overcome the inertial trend and maintain reset stability, thereby realizing inertial buffering and inertial resistance in the instantaneous movement start and stop stage of the ink cartridge, reducing the disturbance of the ink cartridge under the action of inertia, maintaining the stability of the internal ink, avoiding inertial agitation, and realizing rapid stabilization after inertial buffering.

[0022] Example 2: When the position of the moving shock-absorbing frame drifts out of the set moving boundary and collides with the boundary rigid structure, the buffer compensation component 14 on the outside of the main frame 1 first contacts the collision part, compressing the buffer pad 141 in the buffer compensation component 14 while squeezing and pushing the middle connecting rod 143, so that the buffer pad 141 is squeezed and deformed, while driving the electromagnet 2 142 and the trigger plate 144 on both sides to move synchronously, and the displacement of the electromagnet 2 142 is synchronized with the compression of the buffer pad 141, and the electromagnet 2 142 gradually approaches the magnetic plate 8 on one side of the inner frame 2, and at the same time the trigger plate 144 moves and switches from a non-contact state to a contact state with the induction part 2 15, and the contact is energized, corresponding to the external control The controller receives the power-on signal and controls to turn off all electromagnets 13, so that the two sides of the inner frame 2 are no longer disturbed by the magnetic repulsion force of electromagnet 13. The inner frame 2 generates an enhanced magnetic repulsion force through the magnetic plate 8 on one side and the electromagnet 2 142 that is approaching by collision and extrusion, thereby pushing the inner frame 2 to elastically displace during collision and extrusion through the synchronous magnetic repulsion force in a single direction, and the displacement amount compensates for the compression amount of the buffer pad 141, that is, the drift amount of the main frame 1 during collision and elastic extrusion. While the main frame 1 completes elastic buffering through the buffer compensation component 14 to weaken the vibration damage, it controls the ink cartridge position after the drift of the main frame 1 to retreat and supplement the excess displacement of the drift. After supplementation, the ink cartridge maintains the actual boundary position for inkjet printing.

[0023] First, by utilizing the buffer compensation component 14 on the outside of the main frame 1, on the one hand, the buffer compensation component 14 is used to achieve collision buffering on the outside to reduce collision damage. On the other hand, when the ink cartridge follows the main frame 1 to move to the set boundary and drifts beyond the set position, the collision and extrusion of the buffer compensation component 14 and the rigid structure of the set boundary are used to quickly and automatically release the aforementioned magnetic buffer mechanism on the outside of the inner frame 2, and the actual drift amount is reflected according to the collision buffer extrusion amount. The collision buffer extrusion effect causes the inner frame 2 to move in the specified direction, and the displacement amount is consistent with the drift amount. Therefore, when the main frame 1 drifts beyond the set boundary, the internal frame 2 drives the ink cartridge to compensate for the displacement, ensuring that the ink cartridge position is maintained at the set boundary position, and completing precise inkjet printing at the set boundary position, avoiding the ink cartridge following the drift when the boundary drifts, causing large-scale oscillation of the ink inside the ink cartridge, thereby forming a large number of bubbles inside the ink cartridge, avoiding inkjet printing deviation and omission caused by bubbles, and ensuring printing quality.

[0024] Among them, the multi-directional elastic mechanism includes spring 1 3, spring 2 4, a fixed plate 5 and a damping layer 11. Spring 1 3 is horizontally arranged on the outside of the inner frame 2, one end of spring 1 3 is fixedly connected to the inner frame 2, and the other end of spring 1 3 is fixed to the inner wall of the main frame 1. Spring 2 4 is symmetrically distributed on the upper and lower surfaces of the inner frame 2. The fixed plate 5 is fixed on the inner wall of the main frame 1. The fixed plate 5 is fixedly connected to the free end of spring 2 4. The damping layer 11 is embedded in the inner wall of the main frame 1, and the damping layer 11 contacts the end of the inner frame 2. The inner wall of the main frame 1 is provided with an adaptation groove 12, and the electromagnet 13 array is distributed in the adaptation groove 12.

[0025] The multi-directional elastic mechanism realizes basic multi-directional elastic buffering through the spring 1 3 on the side and the spring 2 4 at the upper and lower parts to avoid the influence of rigid vibration. The damping layer 11 reduces the elastic vibration in the vertical direction through the damping effect, and performs shock absorption treatment in the horizontal direction through the magnetic buffer mechanism to reduce the inertial influence and elastic buffering agitation.

[0026] Among them, the elastic assembly ring 6 is used for inserting the ink cartridge, and the adsorption and fixing mechanism 7 fixes the inserted ink cartridge through the negative pressure adsorption of the elastic assembly ring 6. A bottom sleeve frame 18 is fixed to the bottom of the inner wall of the main frame 1, and the bottom sleeve frame 18 is adapted to the bottom of the inserted ink cartridge. The elastic assembly ring 6 includes an inner ring body 61 and a vent 62. The vent 62 is opened on the inner wall of the inner ring body 61, and the vent 62 passes through the inner ring body 61 and is connected to the interior of the inner frame 2. The adsorption and fixing mechanism 7 includes a side frame 71, an electric push rod 72, a movable plug 73 and an internal communicating chamber 74. The side frame 71 is fixed on both sides of the inner frame 2, the electric push rod 72 is arranged in the side frame 71, the internal communicating chamber 74 is opened inside the inner frame 2, and the side frame 71 is connected to the internal communicating chamber 74. The movable plug 73 is movably sleeved inside the side frame 71, and the movable plug 73 is fixedly connected to the movable end of the electric push rod 72. One end of the side frame 71 is provided with a bypass hole to bypass the closed chamber of the side frame 71.

[0027] The elastic assembly ring 6 and the adsorption fixing mechanism 7 are used to realize the fixing processing of the ink cartridge by elastic sleeve, avoiding the damage of rigid fixation, and realizing synchronous and effective fixation of multiple groups of ink cartridges. The bypass hole ensures that the air pressure in the chamber on the other side is stable when the movable plug 73 moves, avoiding restricted movement. A sealing ring is provided on the outside of the movable plug 73 to maintain dynamic sealing.

[0028] The main frame 1 has a second sensing portion 15 fixedly disposed therein. When the buffer compensation component 14 is squeezed, it contacts the second sensing portion 15 and controls the first electromagnet 13 to be closed.

[0029] By the self-compression displacement of the buffer compensation component 14 during collision and extrusion, in cooperation with the induction part 2 15 , the electromagnet 1 13 is electrically controlled to be closed, thereby avoiding magnetic interference of the electromagnets 13 on both sides during drift compensation.

[0030] Among them, there are outer cavities 16 on both sides of the main frame 1, the sensing part 15 is nested on the inner wall of the outer cavity 16, the inner wall of the main frame 1 is opened with a sleeve hole 17, and the sleeve hole 17 is connected to the outer cavity 16, and the buffer compensation component 14 is nested in the outer cavity 16.

[0031] The sleeve hole 17 allows the sleeved electromagnet 2 142 to move flexibly, and the outer cavity 16 ensures the compression displacement of the sleeved buffer block 141 , and the outer side surface of the sleeved buffer block 141 contacts the inner wall of the outer cavity 16 .

[0032] Among them, the buffer compensation component 14 includes a buffer pad 141, an electromagnet 2 142, an intermediate connecting rod 143, a trigger plate 144 and a reserved groove 145. The buffer pad 141 is fixedly connected to the outer cavity 16, the electromagnet 2 142 is symmetrically nested in the buffer pad 141, and one end of the electromagnet 2 142 is movable through the sleeve hole 17. The intermediate connecting rod 143 is fixedly nested in the front of the buffer pad 141 and fixed between the two groups of electromagnets 2 142. The reserved groove 145 is opened on both sides of the buffer pad 141. The trigger plate 144 is fixed on the side of the electromagnet 2 142 and is located in the reserved groove 145. The sensing part 2 15 is located on the moving path of the trigger plate 144. When the trigger plate 144 contacts the sensing part 2 15, the external controller is started and the electromagnet 13 is controlled to be completely closed.

[0033] The reserved groove 145 reserves the displacement of the second electromagnet 142, and the second compression state sensing part 15 does not contact the object through the reserved groove 145. The middle connecting rod 143 ensures that the second electromagnet 142 is driven to move during collision and extrusion, and maintains the same displacement as the compression amount.

[0034] The trigger plate 144 and the main touch plate 9 are both conductive foils, and the sensing part 10 and the sensing part 2 15 are AD7147 capacitive sensors.

[0035] The working principle and use process of the present invention are as follows: during use, the ink cartridge is sleeved in the inner ring body 61 of the elastic assembly ring 6, and the elastic inner ring body 61 is used to complete the damping stability after the sleeve is set, and the electric push rod 72 in the adsorption and fixing mechanism 7 is started to drive the movable plug 73 to move along the side frame 71, and suck the air in the internal communication cavity 74 in the connected inner frame 2, so that a low-pressure space is formed inside the internal communication cavity 74. In conjunction with the connected elastic assembly ring 6, when the vent 62 is blocked by the ink cartridge, the ink cartridge is adsorbed and fixed by the negative pressure effect, and the ink cartridge is stably adsorbed and fixed in the inner of the elastic assembly ring 6. When the shock absorbing structure drives the ink cartridge inside to move quickly, the ink cartridge is delayed by the inertia of the inner frame 2 under the action of inertia, causing a position offset between the inner frame 2 and the main frame 1, and as the relative offset action occurs, the main touch plates 9 on both sides of the inner frame 2 slide relatively in the main frame 1, and the main touch plate 9 on one side slides along the surface of the contacted sensing part 10 and gradually increases the contact area, and compresses the spring 3 on the corresponding side, while the main touch plate 9 on the other side moves along the contacted sensing part 10 and reduces the contact area, and at the same time stretches the spring 3 on the corresponding side to achieve inertial buffering, and as the main touch plate 9 The displacement effect of the corresponding sensing part 10 causes the capacitive sensing part 10 to sense the capacitance change when the contact area changes, and receives the circuit change signal through the external control terminal and controls the starting number of the electromagnet 13, so that the starting number of the electromagnet 13 on the side with increased contact area increases, and the starting number of the electromagnet 13 on the side with decreased contact area decreases, thereby increasing the total magnetic force generated by the electromagnet 13 on the side with increased starting number, and generating an enhanced repulsive force on the magnetic plate 8 on the corresponding side of the gradually approaching inner frame 2, pushing the inner frame 2 with inertial displacement in the opposite direction, and moving toward the side that follows the main frame 1. The main frame 1 is reset in the direction of the inertial displacement, so that when the main frame 1 actively displaces and the inner frame 2 and the ink cartridge deflect due to inertia, the springs 1 and 3 on both sides are used for elastic buffering, while increasing the magnetic repulsive force in the relative displacement direction, pushing the elastic buffered inner frame 2 and the ink cartridge to reset quickly in the opposite direction. The ink cartridge completes the elastic buffering and magnetic power reset at the same time during the sudden start and stop phase, the inertial effect is weakened, and the ink agitation phenomenon inside the ink cartridge is reduced. When the shock absorbing structure vibrates up and down, the inner frame 2 and the fixed ink cartridge absorb the vibration potential energy and maintain stability under the combined action of the elastic action of the upper and lower springs 4 and the damping of the end damping layer 11. When the moving shock-absorbing frame drifts out of the set moving boundary and collides with the boundary rigid structure, the buffer compensation component 14 on the outside of the main frame 1 is the first to contact the collision part, compressing the buffer pad 141 in the buffer compensation component 14 while squeezing and pushing the middle connecting rod 143, so that the buffer pad 141 is squeezed and deformed, and the electromagnet 2 142 and the trigger plate 144 on both sides are synchronously displaced, and the displacement of the electromagnet 2 142 is synchronized with the compression of the buffer pad 141, and the electromagnet 2 142 gradually approaches the magnetic plate 8 on one side of the inner frame 2, and at the same time the trigger plate 144 is displaced and switches from a non-contact state to a contact state with the induction part 2 15, and the contact is energized, corresponding to the control of the external controller After receiving the power-on signal and controlling to close all electromagnets 13, the inner frame 2 is no longer disturbed by the magnetic repulsion force of electromagnet 13 on both sides. The inner frame 2 generates an enhanced magnetic repulsion force through the magnetic plate 8 on one side and the electromagnet 2 142 that is approaching by collision and extrusion, thereby pushing the inner frame 2 to elastically displace during collision and extrusion through the synchronous magnetic repulsion force in a single direction, and the displacement compensates for the compression amount of the buffer pad 141, that is, the drift amount of the main frame 1 during collision and elastic extrusion. While the main frame 1 completes elastic buffering through the buffer compensation component 14 to weaken the vibration damage, it controls the ink cartridge position after the drift of the main frame 1 to retreat and supplement the excess displacement of the drift. After supplementation, the ink cartridge maintains the actual boundary position for inkjet printing.
